Power of Suggestion (The Chronicle of Higher Education)

January 30, 2013

The amazing influence of unconscious cues is among the most fascinating discoveries of our time­—that is, if it’s true

By Tom Bartlett

New Haven, Conn.

Power of SuggestionMark Abramson for The Chronicle Review. John Bargh rocked the world of social psychology with experiments that showed the power of unconscious cues over our behavior.

Aframed print of “The Garden of Earthly Delights” hangs above the moss-green, L-shaped sectional in John Bargh’s office on the third floor of Yale University’s Kirtland Hall. Hieronymus Bosch’s famous triptych imagines a natural environment that is like ours (water, flowers) yet not (enormous spiked and translucent orbs). What precisely the 15th-century Dutch master had in mind is still a mystery, though theories abound. On the left is presumably paradise, in the middle is the world, and on the right is hell, complete with knife-faced monster and human-devouring bird devil.

By Bosch’s standard, it’s too much to say the past year has been hellish for Bargh, but it hasn’t been paradise either. Along with personal upheaval, including a lengthy child-custody battle, he has coped with what amounts to an assault on his life’s work, the research that pushed him into prominence, the studies that Malcolm Gladwell called “fascinating” and Daniel Kahneman deemed “classic.” What was once widely praised is now being pilloried in some quarters as emblematic of the shoddiness and shallowness of social psychology. When Bargh responded to one such salvo with a couple of sarcastic blog posts, he was ridiculed as going on a “one-man rampage.” He took the posts down and regrets writing them, but his frustration and sadness at how he’s been treated remain.

Psychology may be simultaneously at the highest and lowest point in its history. Right now its niftiest findings are routinely simplified and repackaged for a mass audience; if you wish to publish a best seller sans bloodsucking or light bondage, you would be well advised to match a few dozen psychological papers with relatable anecdotes and a grabby, one-word title. That isn’t true across the board. Researchers engaged in more technical work on, say, the role of grapheme units in word recognition must comfort themselves with the knowledge that science is, by its nature, incremental. But a social psychologist with a sexy theory has star potential. In the last decade or so, researchers have made astonishing discoveries about the role of consciousness, the reasons for human behavior, the motivations for why we do what we do. This stuff is anything but incremental.

At the same time, psychology has been beset with scandal and doubt. Formerly high-flying researchers like Diederik Stapel, Marc Hauser, and Dirk Smeesters saw their careers implode after allegations that they had cooked their results and managed to slip them past the supposedly watchful eyes of peer reviewers. Psychology isn’t the only field with fakers, but it has its share. Plus there’s the so-called file-drawer problem, that is, the tendency for researchers to publish their singular successes and ignore their multiple failures, making a fluke look like a breakthrough. Fairly or not, social psychologists are perceived to be less rigorous in their methods, generally not replicating their own or one another’s work, instead pressing on toward the next headline-making outcome.

Much of the criticism has been directed at priming. The definitions get dicey here because the term can refer to a range of phenomena, some of which are grounded in decades of solid evidence—like the “anchoring effect,” which happens, for instance, when a store lists a competitor’s inflated price next to its own to make you think you’re getting a bargain. That works. The studies that raise eyebrows are mostly in an area known as behavioral or goal priming, research that demonstrates how subliminal prompts can make you do all manner of crazy things. A warm mug makes you friendlier. The American flag makes you vote Republican. Fast-food logos make you impatient. A small group of skeptical psychologists—let’s call them the Replicators—have been trying to reproduce some of the most popular priming effects in their own labs.

What have they found? Mostly that they can’t get those results. The studies don’t check out. Something is wrong. And because he is undoubtedly the biggest name in the field, the Replicators have paid special attention to John Bargh and the study that started it all.

As in so many other famous psychological experiments, the researcher lies to the subject. After rearranging lists of words into sensible sentences, the subject—a New York University undergraduate—is told that the experiment is about language ability. It is not. In fact, the real test doesn’t begin until the subject exits the room. In the hallway is a graduate student with a stopwatch hidden beneath her coat. She’s pretending to wait for a meeting but really she’s working with the researchers. She times how long it takes the subject to walk from the doorway to a strip of silver tape a little more than 30 feet down the corridor. The experiment hinges on that stopwatch.

The words the subject was asked to rearrange were not random, though they seemed that way (this was confirmed in postexperiment interviews with each subject). They were words like “bingo” and “Florida,” “knits” and “wrinkles,” “bitter” and “alone.” Reading the list, you can almost picture a stooped senior padding around a condo, complaining at the television. A control group unscrambled words that evoked no theme. When the walking times of the two groups were compared, the Florida-knits-alone subjects walked, on average, more slowly than the control group. Words on a page made them act old.

It’s a cute finding. But the more you think about it, the more serious it starts to seem. What if we are constantly being influenced by subtle, unnoticed cues? If “Florida” makes you sluggish, could “cheetah” make you fleet of foot? Forget walking speeds. Is our environment making us meaner or more creative or stupider without our realizing it? We like to think we’re steering the ship of self, but what if we’re actually getting blown about by ghostly gusts?

John Bargh and his co-authors, Mark Chen and Lara Burrows, performed that experiment in 1990 or 1991. They didn’t publish it until 1996. Why sit on such a fascinating result? For starters, they wanted to do it again, which they did. They also wanted to perform similar experiments with different cues. One of those other experiments tested subjects to see if they were more hostile when primed with an African-American face. They were. (The subjects were not African-American.) In the other experiment, the subjects were primed with rude words to see if that would make them more likely to interrupt a conversation. It did.

The researchers waited to publish until other labs had found the same type of results. They knew their finding would be controversial. They knew many people wouldn’t believe it. They were willing to stick their necks out, but they didn’t want to be the only ones.

Since that study was published in the Journal of Personality and Social Psychology,it has been cited more than 2,000 times. Though other researchers did similar work at around the same time, and even before, it was that paper that sparked the priming era. Its authors knew, even before it was published, that the paper was likely to catch fire. They wrote: “The implications for many social psychological phenomena … would appear to be considerable.” Translation: This is a huge deal.

When he was 9 or 10, Bargh decided to become a psychologist. He was in the kitchen of his family’s house in Champaign, Ill., when this revelation came to him. He didn’t know everything that would entail, of course, or what exactly a psychologist did, but he wanted to understand more about human emotion because it was this “mysterious powerful influence on everything.” His dad was an administrator at the University of Illinois, and so he was familiar with university campuses. He liked them. He still does. When he was in high school, he remembers arguing about B.F. Skinner. Everyone else in the class thought Skinner’s ideas were ridiculous. Bargh took the other side, not so much because he embraced the philosophy of radical behaviorism or enjoyed Skinner’s popular writings. It was more because he reveled in contrarianism. “This guy is thinking something nobody else agrees with,” he says now. “Let’s consider that he might be right.”

I met Bargh on a Thursday morning a couple of weeks before Christmas. He was dressed in cable-knit and worn jeans with hiking boots. At 58 he still has a full head of dark, appropriately mussed-up hair. Bargh was reclining on the previously mentioned moss-green sectional while downing coffee to stay alert as he whittled away at a thick stack of finals papers. He rose to greet me, sat back down, and sighed.

The last year has been tough for Bargh. Professionally, the nadir probably came in January, when a failed replication of the famous elderly-walking study was published in the journal PLoS ONE. It was not the first failed replication, but this one stung. In the experiment, the researchers had tried to mirror Bargh’s methods with an important exception: Rather than stopwatches, they used automatic timing devices with infrared sensors to eliminate any potential bias. The words didn’t make subjects act old. They tried the experiment again with stopwatches and added a twist: They told those operating the stopwatches which subjects were expected to walk slowly. Then it worked. The title of their paper tells the story: “Behavioral Priming: It’s All in the Mind, but Whose Mind?”

The paper annoyed Bargh. He thought the researchers didn’t faithfully follow his methods section, despite their claims that they did. But what really set him off was a blog post that explained the results. The post, on the blog Not Exactly Rocket Science, compared what happened in the experiment to the notorious case of Clever Hans, the horse that could supposedly count. It was thought that Hans was a whiz with figures, stomping a hoof in response to mathematical queries. In reality, the horse was picking up on body language from its handler. Bargh was the deluded horse handler in this scenario. That didn’t sit well with him. If the PLoS ONE paper is correct, the significance of his experiment largely dissipates. What’s more, he looks like a fool, tricked by a fairly obvious flaw in the setup.

Bargh responded in two long, detailed posts on his rarely updated Psychology Todayblog. He spelled out the errors he believed were made in the PLoS ONE paper. Most crucially, he wrote, in the original experiment there was no way for the graduate student with the stopwatch to know who was supposed to walk slowly and who wasn’t. The posts were less temperate than most public discourse in science, but they were hardly mouth-foaming rants. He referred to “incompetent or ill-informed researchers,” clearly a shot at the paper’s authors. He mocked the journal where the replication was published as “pay to play” and lacking the oversight of traditional journals. The title of the post, “Nothing in Their Heads,” while perhaps a reference to unconscious behavior, seemed less than collegial.

He also expressed concern for readers who count on “supposedly reputable online media sources for accurate information on psychological science.” This was a dig at the blog post’s author, Ed Yong, who Bargh believes had written an unfair piece. “I was hurt by the things that were said, not just in the article, but in Ed Yong’s coverage of it,” Bargh says now. Yong’s post was more, though, than a credulous summary of the study. He interviewed researchers and provided context. The headline, “Why a classic psychology experiment isn’t what it seemed,” might benefit from softening, but if you’re looking for an example of sloppy journalism, this ain’t it.

While Bargh was dismayed by the paper and the publicity, the authors of the replication were equally taken aback by the severity of Bargh’s reaction. “That really threw us off, that response,” says Axel Cleeremans, a professor of cognitive science at the Université Libre de Bruxelles. “It was obvious that he was so dismissive, it was close to frankly insulting. He described us as amateur experimentalists, which everyone knows we are not.” Nor did they feel that his critique of their methods was valid. Even so, they tried the experiment again, taking into account Bargh’s concerns. It still didn’t work.

Bargh took his blog posts down after they were criticized. Though his views haven’t changed, he feels bad about his tone. In our conversations over the last month or so, Bargh has at times vigorously defended his work, pointing to a review he published recently in Trends in Cognitive Sciences that marshals recent priming studies into a kind of state-of-the-field address. Short version: Science marches on, priming’s doing great.

He complains that he has been a victim of scientific bullying (and some sympathetic toward Bargh use that phrase, too). There are other times, though, when he just seems crushed. “You invest your whole career and life in something, and to have this happen near the end of it—it’s very hard to take,” he says. Priming is what Bargh is known for. When he says “my name is a symbol that stands for these kinds of effects,” he’s not being arrogant. That’s a fact. Before the 1996 paper, he had already published respected and much-cited work on unconscious, automatic mental processes, but priming has defined him. In an interview on the Web site Edge a few years ago, back before the onslaught, he explained his research goals: “We have a trajectory downward, always downward, trying to find simple, basic causes and with big effects. We’re looking for simple things—not anything complicated—simple processes or concepts that then have profound effects.” The article labeled him “the simplifier.”

When I ask if he still believes in these effects, he says yes. They have been replicated in multiple labs. Some of those replications have been exact: stopwatch, the same set of words, and so on. Others have been conceptual. While they explore the same idea, maybe the study is about handwriting rather than walking. Maybe it’s about obesity rather than elderly stereotypes. But the gist is the same. “It’s not just my work that’s under attack here,” Bargh says. “It’s lots of people’s research being attacked and dismissed.” He has moments of doubt. How could he not? It’s deeply unsettling to have someone scrutinizing your old papers, looking for inconsistencies, even if you’re fairly confident about what you’ve accomplished. “Maybe there’s something we were doing that I didn’t realize,” he says, explaining the thoughts that have gone through his head. “You start doing that examination.”

So why not do an actual examination? Set up the same experiments again, with additional safeguards. It wouldn’t be terribly costly. No need for a grant to get undergraduates to unscramble sentences and stroll down a hallway. Bargh says he wouldn’t want to force his graduate students, already worried about their job prospects, to spend time on research that carries a stigma. Also, he is aware that some critics believe he’s been pulling tricks, that he has a “special touch” when it comes to priming, a comment that sounds like a compliment but isn’t. “I don’t think anyone would believe me,” he says.

Harold Pashler wouldn’t. Pashler, a professor of psychology at the University of California at San Diego, is the most prolific of the Replicators. He started trying priming experiments about four years ago because, he says, “I wanted to see these effects for myself.” That’s a diplomatic way of saying he thought they were fishy. He’s tried more than a dozen so far, including the elderly-walking study. He’s never been able to achieve the same results. Not once.

This fall, Daniel Kahneman, the Nobel Prize-winning psychologist, sent an e-mail to a small group of psychologists, including Bargh, warning of a “train wreck looming” in the field because of doubts surrounding priming research. He was blunt: “I believe that you should collectively do something about this mess. To deal effectively with the doubts you should acknowledge their existence and confront them straight on, because a posture of defiant denial is self-defeating,” he wrote.

Strongly worded e-mails from Nobel laureates tend to get noticed, and this one did. He sent it after conversations with Bargh about the relentless attacks on priming research. Kahneman cast himself as a mediator, a sort of senior statesman, endeavoring to bring together believers and skeptics. He does have a dog in the fight, though: Kahneman believes in these effects and has written admiringly of Bargh, including in his best seller Thinking, Fast and Slow.

On the heels of that message from on high, an e-mail dialogue began between the two camps. The vibe was more conciliatory than what you hear when researchers are speaking off the cuff and off the record. There was talk of the type of collaboration that Kahneman had floated, researchers from opposing sides combining their efforts in the name of truth. It was very civil, and it didn’t lead anywhere.

In one of those e-mails, Pashler issued a challenge masquerading as a gentle query: “Would you be able to suggest one or two goal priming effects that you think are especially strong and robust, even if they are not particularly well-known?” In other words, put up or shut up. Point me to the stuff you’re certain of and I’ll try to replicate it. This was intended to counter the charge that he and others were cherry-picking the weakest work and then doing a victory dance after demolishing it. He didn’t get the straightforward answer he wanted. “Some suggestions emerged but none were pointing to a concrete example,” he says.

One possible explanation for why these studies continually and bewilderingly fail to replicate is that they have hidden moderators, sensitive conditions that make them a challenge to pull off. Pashler argues that the studies never suggest that. He wrote in that same e-mail: “So from our reading of the literature, it is not clear why the results should be subtle or fragile.”

Bargh contends that we know more about these effects than we did in the 1990s, that they’re more complicated than researchers had originally assumed. That’s not a problem, it’s progress. And if you aren’t familiar with the literature in social psychology, with the numerous experiments that have modified and sharpened those early conclusions, you’re unlikely to successfully replicate them. Then you will trot out your failure as evidence that the study is bogus when really what you’ve proved is that you’re no good at social psychology.

Pashler can’t quite disguise his disdain for such a defense. “That doesn’t make sense to me,” he says. “You published it. That must mean you think it is a repeatable piece of work. Why can’t we do it just the way you did it?”

That’s how David Shanks sees things. He, too, has been trying to replicate well-known priming studies, and he, too, has been unable to do so. In a forthcoming paper, Shanks, a professor of psychology at University College London, recounts his and his several co-authors’ attempts to replicate one of the most intriguing effects, the so-called professor prime. In the study, one group was told to imagine a professor’s life and then list the traits that brought to mind. Another group was told to do the same except with a soccer hooligan rather than a professor.

The groups were then asked questions selected from the board game Trivial Pursuit, questions like “Who painted ‘Guernica’?” and “What is the capital of Bangladesh?” (Picasso and Dhaka, for those playing at home.) Their scores were then tallied. The subjects who imagined the professor scored above a control group that wasn’t primed. The subjects who imagined soccer hooligans scored below the professor group and below the control. Thinking about a professor makes you smart while thinking about a hooligan makes you dumb. The study has been replicated a number of times, including once on Dutch television.

Shanks can’t get the result. And, boy, has he tried. Not once or twice, but nine times.

The skepticism about priming, says Shanks, isn’t limited to those who have committed themselves to reperforming these experiments. It’s not only the Replicators. “I think more people in academic psychology than you would imagine appreciate the historical implausibility of these findings, and it’s just that those are the opinions that they have over the water fountain,” he says. “They’re not the opinions that get into the journalism.”

Like all the skeptics I spoke with, Shanks believes the worst is yet to come for priming, predicting that “over the next two or three years you’re going to see an avalanche of failed replications published.” The avalanche may come sooner than that. There are failed replications in press at the moment and many more that have been completed (Shanks’s paper on the professor prime is in press at PLoS ONE). A couple of researchers I spoke with didn’t want to talk about their results until they had been peer reviewed, but their preliminary results are not encouraging.

Ap Dijksterhuis is the author of the professor-prime paper. At first, Dijksterhuis, a professor of psychology at Radboud University Nij­megen, in the Netherlands, wasn’t sure he wanted to be interviewed for this article. That study is ancient news—it was published in 1998, and he’s moved away from studying unconscious processes in the last couple of years, in part because he wanted to move on to new research on happiness and in part because of the rancor and suspicion that now accompany such work. He’s tired of it.

The outing of Diederik Stapel made the atmosphere worse. Stapel was a social psychologist at Tilburg University, also in the Netherlands, who was found to have committed scientific misconduct in scores of papers. The scope and the depth of the fraud were jaw-dropping, and it changed the conversation. “It wasn’t about research practices that could have been better. It was about fraud,” Dijksterhuis says of the Stapel scandal. “I think that’s playing in the background. It now almost feels as if people who do find significant data are making mistakes, are doing bad research, and maybe even doing fraudulent things.”

In the e-mail discussion spurred by Kahneman’s call to action, Dijk­sterhuis laid out a number of possible explanations for why skeptics were coming up empty when they attempted priming studies. Cultural differences, for example. Studying prejudice in the Netherlands is different from studying it in the United States. Certain subjects are not susceptible to certain primes, particularly a subject who is unusually self-aware. In an interview, he offered another, less charitable possibility. “It could be that they are bad experimenters,” he says. “They may turn out failures to replicate that have been shown by 15 or 20 people already. It basically shows that it’s something with them, and it’s something going on in their labs.”

Joseph Cesario is somewhere between a believer and a skeptic, though these days he’s leaning more skeptic. Cesario is a social psychologist at Michigan State University, and he’s successfully replicated Bargh’s elderly-walking study, discovering in the course of the experiment that the attitude of a subject toward the elderly determined whether the effect worked or not. If you hate old people, you won’t slow down. He is sympathetic to the argument that moderators exist that make these studies hard to replicate, lots of little monkey wrenches ready to ruin the works. But that argument only goes so far. “At some point, it becomes excuse-making,” he says. “We have to have some threshold where we say that it doesn’t exist. It can’t be the case that some small group of people keep hitting on the right moderators over and over again.”

Cesario has been trying to replicate a recent finding of Bargh’s. In that study, published last year in the journal Emotion, Bargh and his co-author, Idit Shalev, asked subjects about their personal hygiene habits—how often they showered and bathed, for how long, how warm they liked the water. They also had subjects take a standard test to determine their degree of social isolation, whether they were lonely or not. What they found is that lonely people took longer and warmer baths and showers, perhaps substituting the warmth of the water for the warmth of regular human interaction.

That isn’t priming, exactly, though it is a related unconscious phenomenon often called embodied cognition. As in the elderly-walking study, the subjects didn’t realize what they were doing, didn’t know they were bathing longer because they were lonely. Can warm water alleviate feelings of isolation? This was a result with real-world applications, and reporters jumped on it. “Wash the loneliness away with a long, hot bath,” read an NBC News headline.

Bargh’s study had 92 subjects. So far Cesario has run more than 2,500 through the same experiment. He’s found absolutely no relationship between bathing and loneliness. Zero. “It’s very worrisome if you have people thinking they can take a shower and they can cure their depression,” he says. And he says Bargh’s data are troublesome. “Extremely small samples, extremely large effects—that’s a red flag,” he says. “It’s not a red flag for people publishing those studies, but it should be.”

Even though he is, in a sense, taking aim at Bargh, Cesario thinks it’s a shame that the debate over priming has become so personal, as if it’s a referendum on one man. “He has the most eye-catching findings. He always has,” Cesario says. “To the extent that some of his effects don’t replicate, because he’s identified as priming, it casts doubt on the entire body of research. He is priming.”

That has been the narrative. Bargh’s research is crumbling under scrutiny and, along with it, perhaps priming as a whole. Maybe the most exciting aspect of social psychology over the last couple of decades, these almost magical experiments in which people are prompted to be smarter or slower without them even knowing it, will end up as an embarrassing footnote rather than a landmark achievement.

Then along comes Gary Latham.

Latham, an organizational psychologist in the management school at the University of Toronto, thought the research Bargh and others did was crap. That’s the word he used. He told one of his graduate students, Amanda Shantz, that if she tried to apply Bargh’s principles it would be a win-win. If it failed, they could publish a useful takedown. If it succeeded … well, that would be interesting.

They performed a pilot study, which involved showing subjects a photo of a woman winning a race before the subjects took part in a brainstorming task. As Bargh’s research would predict, the photo made them perform better at the brainstorming task. Or seemed to. Latham performed the experiment again in cooperation with another lab. This time the study involved employees in a university fund-raising call center. They were divided into three groups. Each group was given a fact sheet that would be visible while they made phone calls. In the upper left-hand corner of the fact sheet was either a photo of a woman winning a race, a generic photo of employees at a call center, or no photo. Again, consistent with Bargh, the subjects who were primed raised more money. Those with the photo of call-center employees raised the most, while those with the race-winner photo came in second, both outpacing the photo-less control. This was true even though, when questioned afterward, the subjects said they had been too busy to notice the photos.

Latham didn’t want Bargh to be right. “I couldn’t have been more skeptical or more disbelieving when I started the research,” he says. “I nearly fell off my chair when my data” supported Bargh’s findings.

That experiment has changed Latham’s opinion of priming and has him wondering now about the applications for unconscious primes in our daily lives. Are there photos that would make people be safer at work? Are there photos that undermine performance? How should we be fine-tuning the images that surround us? “It’s almost scary in lots of ways that these primes in these environments can affect us without us being aware,” he says. Latham hasn’t stopped there. He’s continued to try experiments using Bargh’s ideas, and those results have only strengthened his confidence in priming. “I’ve got two more that are just mind-blowing,” he says. “And I know John Bargh doesn’t know about them, but he’ll be a happy guy when he sees them.”

Latham doesn’t know why others have had trouble. He only knows what he’s found, and he’s certain about his own data. In the end, Latham thinks Bargh will be vindicated as a pioneer in understanding unconscious motivations. “I’m like a converted Christian,” he says. “I started out as a devout atheist, and now I’m a believer.”

Following his come-to-Jesus transformation, Latham sent an e-mail to Bargh to let him know about the call-center experiment. When I brought this up with Bargh, his face brightened slightly for the first time in our conversation. “You can imagine how that helped me,” he says. He had been feeling isolated, under siege, worried that his legacy was becoming a cautionary tale. “You feel like you’re on an island,” he says.

Though Latham is now a believer, he remains the exception. With more failed replications in the pipeline, Dijksterhuis believes that Kahneman’s looming-train-wreck letter, though well meaning, may become a self-fulfilling prophecy, helping to sink the field rather than save it. Perhaps the perception has already become so negative that further replications, regardless of what they find, won’t matter much. For his part, Bargh is trying to take the long view. “We have to think about 50 or 100 years from now—are people going to believe the same theories?” he says. “Maybe it’s not true. Let’s see if it is or isn’t.”

O recorde de Dilma (Brasileiros)

3 de fevereiro de 2013 – 10:37

Metade dos impostos arrecadados pelo governo são destinados a programas sociais

50,4%. Essa é a porcentagem do que o governo federal gasta de sua arrecadação com programas sociais e verbas destinadas diretamente a famílias registradas em políticas de auxílio. As informações são da Folha de S. Paulo.

O número, um recorde nacional, mostra que entre regime geral de previdência, amparo ao trabalhador e assistência, o governo da presidenta Dilma Rousseff distribuí R$ 405,2 bilhões. O valor representa 9,2% do Produto Interno Bruto (PIB) brasileiro.

O aumento das despesas do governo com medidas sociais podem ser creditados ao aumento do salário mínimo, que subiu 7,5% acima da inflação, maior guinada desde o ano de 2006. Assim como as aposentadorias, pensões e benefícios trabalhistas, os programas assistências seguem o salário mínimo como referência.

A política social explica a carga de impostos nacional, que hoje representa 35% da arrecadação do governo. Em outros países emergentes da América Latina e da Ásia, a carga tributária representa entre 20% e 25% da arrecadação. Recentemente, a Argentina subiu seus impostos e se aproximou dos valores tributados arrecadados pelo Brasil.

Queda da taxa de desemprego

Os valores investidos pelo governo federal parecem estar surtindo efeito junto à população. Na última quinta-feira, dia 31, o Instituto Brasileiro de Geografia e Estatística (IBGE) divulgou que a taxa de desemprego no país em 2012 foi de 5,5%, a menor da série histórica iniciada no ano de 2003.

Em relação ao seguro-desemprego, um novo decreto editado recentemente apresenta mudanças para quem deseja usufruir do benefício. Agora, trabalhadores que ingressarem no programa pela terceira vez terão que participar de curso profissionalizante para garantir o direito.

Programa símbolo do governo de Lula, o Bolsa Família representa a maior despesa entre os programas sociais mantidos pelo governo federal. Criado há quase dez anos, o programa passou por significativa reformulação sob a tutela de Dilma Rousseff.

A linha de ação da presidenta busca beneficiar famílias que estão abaixo da linha da miséria. Enquadram-se nessa categoria famílias cujo rendimento é inferior ao valor de R$ 70 por pessoa. Em virtude dessa meta, a despesa com o programa saltou de R$ 13,6 bilhões no fim do governo Lula para R$ 20,5 bilhões em 2012. O Bolsa Família beneficia 13,9 milhões de famílias em todo o Brasil.

Dez anos de Fome Zero ajuda Guaribas (PI) a elevar IDH (Agência Brasil)

Da Agência Brasil – 03/02/2013

Lucas Rodrigues
Enviado Especial da EBC

Guaribas (PI) – Lançado no dia 3 de fevereiro de 2003, no município com o menor Índice de Desenvolvimento Humano (IDH) do país, o Programa Fome Zero foi criado com o objetivo de erradicar a miséria, com a transferência de renda e garantindo o alimento para as famílias que viviam na extrema pobreza. Hoje, o Brasil ainda tem pelo menos 5,3 milhões de pessoas sobrevivendo com menos de R$ 70 por mês, diferentemente do início dos anos 2000, quando eram 28 milhões de pessoas abaixo da linha da pobreza.

Nos último dez anos, esse número vem diminuindo. Em parte, por causa de políticas públicas de ampliação do trabalho formal, do apoio à agricultura e da transferência de renda. Hoje, a iniciativa, que ganhou o nome de Bolsa Família, chega a quase 14 milhões de lares. Ela nasceu do Programa Fome Zero, criado para garantir no mínimo três refeições por dia a todos os brasileiros. E foi do interior do Nordeste que essa iniciativa partiu para o restante do país.

Depois de dez anos, a Agência Brasil voltou a Guaribas, no sul do Piauí, escolhida como a primeira beneficiária do programa de transferência de renda. Localizada a 600 quilômetros ao sul da capital, Teresina, Guaribas não oferecia condições básicas para uma vida digna de sua população: faltava comida no prato das famílias, que, na maioria das vezes, só tinham feijão para comer. Não havia rede elétrica e poucas casas tinham fogão a gás.

Mulheres e crianças andavam quilômetros para conseguir um pouco de água e essa busca, às vezes, durava o dia inteiro. A dona de casa Gilsa Alves lembra que, naquela época, “era difícil encontrar água para lavar roupa”, no período de seca. “Às vezes, até para tomar banho era com dificuldade”.

O aposentado Eurípedes Correa da Silva não se esquece daquele tempo, quando chegou a trabalhar até de vigia das poucas fontes que eram verdadeiros tesouros durante os longos períodos de seca, com água racionada. Hoje, a água chega, encanada, à casa dele.

Pai de sete filhos, Eurípedes tem televisão e geladeira. Além do dinheiro da lavoura e da aposentadoria, ele recebia o benefício do Fome Zero e agora conta com o Bolsa Família. O benefício chega a 1,5 mil lares e a meta é alcançar 2 mil neste ano, o que representa oito em cada dez moradores da cidade. A coordenadora do programa em Guaribas, Raimunda Correia Maia, diz que “o dinheiro que gira no município, das compras, da sustentação dos filhos, gera desenvolvimento”.

A energia elétrica também chegou a Guaribas e trouxe com ela internet e os telefones celulares. No centro da cidade, há uma praça com ruas calçadas e uma delegacia, além de agências bancárias, dos Correios e escolas. A frota de veículos cresceu e, hoje, o que se vê são motos, em vez de jegues.

O município conquistou o principal objetivo: acabar com a miséria. Mesmo assim, ainda está entre os mais pobres do país e enfrenta o êxodo dos jovens em busca de emprego em grandes cidades. Segundo o IBGE, entre 2000 e 2007, quase 10% dos moradores deixaram Guaribas.

Alan e Rosângela podem ser os próximos. O Bolsa Família e as melhorias na cidade não foram suficientes para manter o casal no município, já que ali os dois não encontram trabalho. Os irmãos já foram para São Paulo e é impossível sustentar a família de oito pessoas com um cartão (do Bolsa Família) de R$ 130.

Quem escolheu ficar na cidade sabe que muita coisa tem que melhorar. O esgoto ainda não é tratado; algumas obras não saíram do lugar, como a do mercado municipal. Até o memorial erguido em homenagem ao Fome Zero está abandonado há anos. Longe de Teresina, os moradores se sentem isolados, principalmente por causa da dificuldade de chegar à cidade mais próxima: são 54 quilômetros de estrada de terra, em péssimo estado, até Caracol.

Isso torna difícil escoar a produção de feijão e milho e faz com que todos os produtos cheguem mais caros. A dificuldade de acesso também prejudica uma das conquistas da região: a unidade de saúde. A doméstica Betânia Andrade Dias Silva levou o filho de 5 anos para uma consulta e não encontrou médicos.

Há mais de um mês, o atendimento é feito apenas por enfermeiras e por um dentista. Mesmo oferecendo um salário que chega a R$ 20 mil, a prefeitura diz que não consegue contratar médicos. O jeito é mandar os pacientes mais graves para as cidades vizinhas.co. Ela desabafa: “É ruim né?! Principalmente numa cidade pequena, na qual você precisa de um atendimento melhor, tem que sair para ir para outra cidade, Caracol, São Raimundo, que fica longe daqui. Por exemplo, caso de urgência, se você estiver à beira da morte, acaba morrendo na estrada… Então, é difícil”.

Mas essa situação pode começar a mudar ainda neste ano. Segundo informou a Secretaria de Transportes do Piauí, o trecho da BR-235 que liga Guaribas a Caracol deve começar a ser asfaltado em outubro. Por enquanto, está sendo asfaltado outro trecho da rodovia, entre Gilbués e Santa Filomena.

O casal Irineu e Eldiene saiu de Guaribas para procurar trabalho em outras cidades, mas voltou. Agora eles levantam, pouco a pouco, uma pousada no centro da cidade. Irineu diz que a obra que está fazendo não é “nem tanto pensando no agora”, é para o futuro. “Estou vendo que a cada ano que está passando, Guaribas está desenvolvendo mais”.

A expectativa de Irineu e Edilene é resultado da mudança dessa que já foi a cidade mais pobre do país. Mesmo com dificuldades, os moradores de Guaribas, agora, olham para o futuro com mais esperança e otimismo. Eldiene garante que vai ficar e ver a pousada cheia de clientes.

Flap Over Study Linking Poverty to Biology Exposes Gulfs Among Disciplines (Chronicle of Higher Education)

Flap Over Study Linking Poverty to Biology Exposes Gulfs Among Disciplines 1

A study by two economists that used genetic diversity as a proxy for ethnic and cultural diversity has drawn fierce rebuttals from anthropologists and geneticists.

By Paul Voosen

Oded Galor and Quamrul Ashraf once thought their research into the causes of societal wealth would be seen as a celebration of diversity. However it has been described, though, it has certainly not been celebrated. Instead, it has sparked a dispute among scholars in several disciplines, many of whom are dubious of any work linking societal behavior to genetics. In the latest installment of the debate, 18 Harvard University scientists have called their work “seriously flawed on both factual and methodological grounds.”

Mr. Galor and Mr. Ashraf, economists at Brown University and Williams College, respectively, have long been fascinated by the historical roots of poverty. Six years ago, they began to wonder if a society’s diversity, in any way, could explain its wealth. They probed tracts of interdisciplinary data and decided they could use records of genetic diversity as a proxy for ethnic and cultural diversity. And after doing so, they found that, yes, a bit of genetic diversity did seem to help a society’s economic growth.

Since last fall, when the pair’s work began to filter out into the broader scientific world, their study has exposed deep rifts in how economists, anthropologists, and geneticists talk—and think. It has provoked calls for caution in how economists use genetic data, and calls of persecution in response. And all of this happened before the study was finally published, in the American Economic Review this month.

“Through this analysis, we’re getting a better understanding of how the world operates in order to alleviate poverty,” Mr. Ashraf said. Any other characterization, he added, is a “gross misunderstanding.”

‘Ethical Quagmires’

A barrage of criticism has been aimed at the study since last fall by a team of anthropologists and geneticists at Harvard. The critique began with a short, stern letter, followed by a rejoinder from the economists; now an expanded version of the Harvard critique will appear in February inCurrent Anthropology.

Fundamentally, the dispute comes down to issues of data selection and statistical power. The paper is a case of “garbage in, garbage out,” the Harvard group says. The indicators of genetic diversity that the economists use stem from only four or five independent points. All the regression analysis in the world can’t change that, said Nick Patterson, a computational biologist at Harvard and MIT’s Broad Institute.

“The data just won’t stand for what you’re claiming,” Mr. Patterson said. “Technical statistical analysis can only do so much for you. … I will bet you that they can’t find a single geneticist in the world who will tell them what they did was right.”

In some respects, the study has become an exemplar for how the nascent field of “genoeconomics,” a discipline that seeks to twin the power of gene sequencing and economics, can go awry. Connections between behavior and genetics rightly need to clear high bars of evidence, said Daniel Benjamin, an economist at Cornell University and a leader in the field who has frequently called for improved rigor.

“It’s an area that’s fraught with an unfortunate history and ethical quagmires,” he said. Mr. Galor and Mr. Ashraf had a creative idea, he added, even if all their analysis doesn’t pass muster.

“I’d like to see more data before I’m convinced that their [theory] is true,” said Mr. Benjamin, who was not affiliated with the study or the critique. The Harvard critics make all sorts of complaints, many of which are valid, he said. “But fundamentally the issue is that there’s just not that much independent data.”

Claims of ‘Outsiders’

The dispute also exposes issues inside anthropology, added Carl Lipo, an anthropologist at California State University at Long Beach who is known for his study of Easter Island. “Anthropologists have long tried to walk the line whereby we argue that there are biological origins to much of what makes us human, without putting much weight that any particular attribute has its origins in genetics [or] biology,” he said.

The debate often erupts in lower-profile ways and ends with a flurry of anthropologists’ putting down claims by “outsiders,” Mr. Lipo said. (Mr. Ashraf and Mr. Galor are “out on a limb” with their conclusions, he added.) The angry reaction speaks to the limits of anthropology, which has been unable to delineate how genetics reaches up through the idiosyncratic circumstances of culture and history to influence human behavior, he said.

Certainly, that reaction has been painful for the newest pair of outsiders.

Mr. Galor is well known for studying the connections between history and economic development. And like much scientific work, his recent research began in reaction to claims made by Jared Diamond, the famed geographer at the University of California at Los Angeles, that the development of agriculture gave some societies a head start. What other factors could help explain that distribution of wealth? Mr. Galor wondered.

Since records of ethnic or cultural diversity do not exist for the distant past, they chose to use genetic diversity as a proxy. (There is little evidence that it can, or can’t, serve as such a proxy, however.) Teasing out the connection to economics was difficult—diversity could follow growth, or vice versa—but they gave it a shot, Mr. Galor said.

“We had to find some root causes of the [economic] diversity we see across the globe,” he said.

They were acquainted with the “Out of Africa” hypothesis, which explains how modern human beings migrated from Africa in several waves to Asia and, eventually, the Americas. Due to simple genetic laws, those serial waves meant that people in Africa have a higher genetic diversity than those in the Americas. It’s an idea that found support in genetic sequencing of native populations, if only at the continental scale.

Combining the genetics with population-density estimates—data the Harvard group says are outdated—along with deep statistical analysis, the economists found that the low and high diversity found among Native Americans and Africans, respectively, was detrimental to development. Meanwhile, they found a sweet spot of diversity in Europe and Asia. And they stated the link in sometimes strong, causal language, prompting another bitter discussion with the Harvard group over correlation and causation.

An ‘Artifact’ of the Data?

The list of flaws found by the Harvard group is long, but it boils down to the fact that no one has ever made a solid connection between genes and poverty before, even if genetics are used only as a proxy, said Jade d’Alpoim Guedes, a graduate student in anthropology at Harvard and the critique’s lead author.

“If my research comes up with findings that change everything we know,” Ms. d’Alpoim Guedes said, “I’d really check all of my input sources. … Can I honestly say that this pattern that I see is true and not an artifact of the input data?”

Mr. Ashraf and Mr. Galor found the response to their study, which they had previewed many times over the years to other economists, to be puzzling and emotionally charged. Their critics refused to engage, they said. They would have loved to present their work to a lecture hall full of anthropologists at Harvard. (Mr. Ashraf, who’s married to an anthropologist, is a visiting scholar this year at Harvard’s Kennedy School.) Their gestures were spurned, they said.

“We really felt like it was an inquisition,” Mr. Galor said. “The tone and level of these arguments were really so unscientific.”

Mr. Patterson, the computational biologist, doesn’t quite agree. The conflict has many roots but derives in large part from differing standards for publication. Submit the same paper to a leading genetics journal, he said, and it would not have even reached review.

“They’d laugh at you,” Mr. Patterson said. “This doesn’t even remotely meet the cut.”

In the end, it’s unfortunate the economists chose genetic diversity as their proxy for ethnic diversity, added Mr. Benjamin, the Cornell economist. They’re trying to get at an interesting point. “The genetics is really secondary, and not really that important,” he said. “It’s just something that they’re using as a measure of the amount of ethnic diversity.”

Mr. Benjamin also wishes they had used more care in their language and presentation.

“It’s not enough to be careful in the way we use genetic data,” he said. “We need to bend over backwards being careful in the way we talk about what the data means; how we interpret findings that relate to genetic data; and how we communicate those findings to readers and the public.”

Mr. Ashraf and Mr. Galor have not decided whether to respond to the Harvard critique. They say they can, point by point, but that ultimately, the American Economic Review’s decision to publish the paper as its lead study validates their work. They want to push forward on their research. They’ve just released a draft study that probes deeper into the connections between genetic diversity and cultural fragmentation, Mr. Ashraf said.

“There is much more to learn from this data,” he said. “It is certainly not the final word.”

Juridiquês (Sopro 83)


Juridiquês
 Alexandre Nodari


Se tivesse sido possível construir a torre de Babel sem escalá-la até o topo, ela teria sido permitida
(Kafka)

1. Tramita no Congresso Nacional um projeto de lei, de autoria de Maria do Rosário, que pretende acrescer ao artigo 458 do Código de Processo Civil, que diz respeito aos “requisitos essenciais da sentença”, um quarto inciso, tornando obrigatória “a reprodução do dispositivo da sentença em linguagem coloquial, sem a utilização de termos exclusivos da Linguagem técnico-jurídica e acrescida das considerações que a autoridade Judicial entender necessárias, de modo que a prestação jurisdicional possa ser plenamente compreendida por qualquer pessoa do povo”. É evidente que a proposta visa ampliar o acesso à Justiça e tem intenção democratizadora. Todavia, se, por si só, o projeto parece ser razoável, confrontado com a torrente de leis ou projetos de lei que visam regular cada aspecto da vida humana, do cigarro à linguagem (há poucos anos, o comunista-ruralista Aldo Rebelo tentou banir os estrangeirismos do português), não há como não termos uma postura ao menos cética diante dele. Se o projeto em si pode ser bom, contextualizado com a inflação normativa que visa purificar cada aspecto da vida humana, não há como não termos ressalvas. O desejo de limpeza, de higienização, de clareza, atravessa a sociedade como um todo – e tal desejo atende a anseios do poder, ou, pelo menos, é canalizado por ele. Dominique Laporte, em sua História da merda, lembra que foi no mesmo ano de 1539 que a França: 1) primeiro obrigou que as leis, os atos administrativos, os processos judiciais e os documentos notariais, fossem redigidos em vernáculo, eliminando as ambigüidades e incertezas do latim, e possibilitando a “clareza”; 2) e, logo a seguir, proibiu que os cidadãos jogassem na rua seus excrementos – suas fezes e suas urinas. Limpar a linguagem e limpar a cidade: a centralização do poder que daria naquilo que chamamos vulgarmente de absolutismo tem suas raízes nessa vontade de pureza e limpeza, nesse ideal cristalino. Todavia, para além desse “desejo de clareza”, é interessante atentarmos para uma espécie de ato falho contido na “Justificação” do projeto de lei; talvez não seja, de fato, um ato falho, mas algo intencional, o que pouco importa. O parágrafo final da justificativa fala em “tradução para o vernáculo comum do texto técnico da sentença judicial”, como se as sentenças não fossem escritas em português. Há aí uma verdade essencial sobre o Direito: ele é uma linguagem diferente do “vernáculo comum”. Na famosa Apologia de Sócrates, o velho sábio, ao falar diante do tribunal que o acusava de impiedade, diz ser “um estrangeiro à língua” que ali se fala, e pede pra ser tratado como se fosse um estrangeiro que não sabe o grego. O Direito não é uma língua estrangeira como o inglês ou o latim são em relação ao português ou ao grego: o Direito é a língua portuguesa ou grega em outro regime de funcionamento. Diante do Direito pátrio, somos como estrangeiros que não conhecem a própria língua. Mas qual é o regime de funcionamento daquela linguagem que atende, no “vernáculo comum”, pelo nome de “juridiquês”?

2. Em um belíssimo texto sobre a figura do notário, Salvatore Satta, um dos juristas mais brilhantes do século XX, resumiu o “drama” do escrivão ou escrevente, esses mediadores entre os plebeus e os juristas, do seguinte modo: “Conhecer o querer que aquele que quer não conhece”. Não é que “aquele que quer” não conheça o seu querer; “aquele que quer” não sabe traduzi-lo juridicamente. Ou seja, continua Satta, o que o notário faz, de fato, é “reduzir a vontade da parte enquanto vontade do ordenamento”. Eis o sentido do brocardo latino Da mihi factum, dabo tibi jus (“Exponha o fato e te direi o direito”): reduzir a “volição em vista de um escopo prático que a parte se propõe a atingir enquanto vontade jurídica e juridicamente tipificada”, ou seja, traduzir uma vontade, um fato, um ato da vida, em tipos jurídicos. O Direito não lida propriamente com fatos ou atos, mas com fatos ou atos jurídicos, que correspondam a certos tipos previstos. Passar um ato ou fato da vida ao Direito é tipificá-lo. Nesse sentido, o tipo talvez seja o elemento gramatical básico da linguagem jurídica. Mas o que exatamente é um tipo? Quem melhor refletiu sobre a noção de “tipo” não foi um jurista, mas um sociólogo, Max Weber, sedimentando, com os chamados “tipo ideais”, seu método em oposição ao método empírico-comparatista de Durkheim. Para Weber, os tipos puros ou ideais não poderiam ser encontrados “na realidade”; o que existia “de fato” era sempre um compósito, mais ou menos híbrido, de tipos que – e daí a sua natureza circular – se construíam a partir de elementos dispersos nesta mesma “realidade” em que eram aplicados. A própria etimologia de tipo já indica este seu caráter ambíguo, entre a empiria e a abstração: o gregotypos significa imagem, vestígio, rastro, ou seja, ausência, índice de uma presença imemorial. Para usar um exemplo de Vilém Flusser: os “typoi são como vestígios que os pés de um pássaro deixam na área da praia. Então, a palavra significa que esses vestígios podem ser utilizados como modelos para classificação do pássaro mencionado”. As duas formas de Direito que o Ocidente conhece são as duas facetas do tipo: a de matriz romano-gerâmica baseia-se nas leis, na abstração, no tipo, para chegar ao caso empírico; e a Common Law, ao contrário, parte dos casos empíricos para convertê-los em típicos, em abstratos. Mas, como diz Satta, na tipificação, há uma redução, algo se perde – inclusive a linguagem comum.

3. O tipo atende a uma necessidade básica do funcionamento do Direito, e domodus operandi de sua linguagem específica (ou típica): a prescrição. “Se” acontece ou está presente o tipo X, “então” a conseqüência, a sanção, é Y. O problema de todo processo reside em saber se o acontecimento A da vida corresponde ou não ao tipo X para que a conseqüência Y se dê. Como as normas se fundamentam em tipos, que não passam de linguagem sem relação necessária com as coisas e os fatos da vida, é preciso uma construção discursiva que conecte o acontecimento da vida ao tipo jurídico – se o Direito fosse pura subsunção, lembra Giorgio Agamben, poderíamos abdicar desse imenso aparato judicial chamado processo, e que envolve não só o juiz, o advogado e o promotor, mas inúmeros outros mediadores entre a linguagem comum e a linguagem jurídica (o notário, o taquígrafo, etc.). Por isso, para que se dê essa tipificação, não só o fato relevante juridicamente precisa passar à forma de tipo, como também tudo aquilo que o cerca, para que haja a redução da singularidade à tipificação, ou seja, à reprodução daquele caso típico (na forma de jurisprudência). Sabemos bem como isso funciona: dos boletins de ocorrência até as sentenças, os fatos da vida são narrados em uma linguagem que os torna típicos, abstratos – e reprodutíveis. Ítalo Calvino sintetizou de forma magistral esse “inquietante” processo de tradução:


O escrivão está diante da máquina de escrever. O interrogado, sentado em frente a ele, responde às perguntas gaguejando ligeiramente, mas preocupado em dizer, com a maior exatidão possível, tudo o que tem de dizer e nem uma palavra a mais: “De manhã cedo, estava indo ao porão para ligar o aquecedor quando encontrei todos aqueles frascos de vinho atrás da caixa de carvão. Peguei um para tomar no jantar. Não estava sabendo que a casa de bebidas lá em cima havia sido arrombada”. Impassível, o escrivão bate rápido nas teclas sua fiel transcrição: “O abaixo assinado, tendo se dirigido ao porão nas primeiras horas da manhã para dar início ao funcionamento da instalação térmica, declara ter casualmente deparado com boa quantidade de produtos vinícolas, localizados na parte posterior do recepiente destinado ao armazenamento do combustível, e ter efetuado a retirada de um dos referidos artigos com a intenção de consumi-lo durante a refeição vespertina, não estando a par do acontecido arrombamento do estabelecimento comercial sobranceiro.”

Calvino chamou a isso de “terror semântico”, ou “antilíngua”: “a fuga diante de cada vocábulo que tenha por si só um significado” – o perigo, a seu ver, era que essa “antilíngua” invadisse a vida comum. Mas nessa fuga diante do vocábulo que tenha por si só um significado, há um avanço para os vocábulos que abranjam mais de um significado, que podem, portanto, ser reproduzidos em várias situações. Essa reprodutibilidade é, como já sublinhamos, essencial à linguagem baseada em tipos – é ela que diferencia, segundo Flusser, a noção de tipo da noção de caractere, que privilegia aquilo que é característico, isto é, próprio.

4. Portanto, o tipo, como elemento básico da gramática jurídica, serve para tornar reprodutíveis as normas diante da singularidade dos acontecimentos da vida; mas, para tanto, ele abstrai (d)esses acontecimentos. Os processos e as normas, compostos de inúmeros tipos, correm, desse modo, ao largo da vida, como se fossem uma narrativa ficcional. O grande romanista Yan Thomas argumenta que “a ficção é um procedimento que (…) pertence à pragmática do direito”. Os antigos romanos, continua Thomas, não tinham pudor em, diante de uma situação excepcional na qual não queriam fazer uma determinada regra, optar por mudar juridicamente a situação no lugar de alterar a regra. Um exemplo, dentre muitos: buscando tornar válidos os testamentos de alguns cidadãos que haviam morrido quando se encontravam sob custódia dos inimigos, o que, por lei, invalidava tais testamentos, a Lex Cornelia, de 81 a.C., optou por criar uma ficção, da qual conhecemos duas versões: 1) a primeira, uma ficção positiva, era considerar os testamentos como se os cidadãos haveriam morrido sob o estatuto normal da cidadania; 2) e a segunda, uma ficção negativa, pela qual os testamentos eram válidos como se os cidadãos não tivessem morrido sob o poder do inimigo. Por que esse afastamento discursivo da “realidade”, da vida? Por que, na narrativa, ou na sua forma, o Direito se afasta do relato comum, cria uma outra realidade, quase uma dimensão paralela? Aqui entra o segundo elemento da linguagem prescricional que caracteriza o Direito, a sanção, o “então Y”. A função do Direito, como sabemos, é alterar, pela linguagem, pela palavra, a realidade, a vida, ou seja, criar palavras eficazes – nem que para garantir a eficácia de uma lei ou de uma sentença seja preciso usar da força pública. (Aliás, não há vernáculo comum o suficiente capaz de explicar a “qualquer pessoa do povo” que aquela sentença que lhe dá ganho de causa ainda precisa ser executada, em um procedimento que demorará mais alguns anos). É dessa função do Direito de alterar a realidade pela linguagem que nasce a ilusão retrospectiva de que haveria um estágio pré-jurídico em que religião, magia e direito coincidiriam. Na verdade, o que o Direito e a Magia partilham é do mesmomodus operandi da linguagem, o performativo (“eu juro”, “eu te condeno”, “eu prometo”), em que, nas palavras de Agamben, “o significado de uma enunciação (…) coincide com a realidade que é ela mesma produzida pelo ato da enunciação”. Nesse sentido, o Direito é, ainda hoje, mágico. O gosto dos juristas pela linguagem ornamental, pelos brocardos, pela linguagem ritual e pelo eufemismo, provem dessa ligação: a realidade pode ser criada a partir de uma linguagem vazia (ou esvaziada, afastada da realidade). Poderíamos, portanto, dizer que o Direito é, ao mesmo tempo, o saber quase mágico deste modus operandi, e aquilo que garante que tal linguagem performativa se transforme em ato – que os contratos sejam cumpridos, que as leis sejam aplicadas, etc. Todavia, para que o Direito opere magicamente sobre a realidade, ele precisa se afastar dela; para que sua linguagem produza efeitos sobre a vida, ela deve se afastar da linguagem que comunica ou que expressa, o “vernáculo comum”.

5. Portanto, talvez o “juridiquês” não seja (apenas) uma prática judiciária que remonta ao bacharelismo e à pseudo-erudição, um resquício antigo que pode ser removido. Antes, talvez ele seja uma prática judiciária constitutiva daquilo que conhecemos por Direito. Emile Benveniste, ao se deter no fato de que o verbo latino iurare (jurar) é o correspondente ao substantivo ius, que estamos habituados a traduzir por “direito”, argumenta que ius deveria, na verdade, significar “a fórmula da conformidade”: “ius, em geral, é realmente uma fórmula, e não um conceito abstrato”. É interessante notar que Benveniste aponta no ius do direito romano este caráter “mágico” que viemos assinalando, em que há separação da linguagem comum e produção de efeitos sobre a realidade – e mostra ainda que tal caráter estaria presente naquele documento que os juristas costumam considerar uma das pedras basilares do direito ocidental, a Lei das XII Tábuas. Diz Benveniste: “iura é a coleção das sentenças de direito. (…) Essesiura (…) são fórmulas que enunciam uma decisão de autoridade; e sempre que esses termos [ius iura] são tomados em seu sentido estrito, encontramos (…) a noção de textos fixados, de fórmulas estabelecidas, cuja posse é o privilégio de certos indivíduos, certas famílias, certas corporações. O tipo exemplar dessesiura é representado pelo código mais antigo de Roma, a Lei das XII Tábuas, originalmente composta por sentenças formulando o estado de ius e pronunciando: ita ius esto. Aqui é o império da palavra, manifestado por termos de sentido concordante; em latim iu-dex. (…) Não é o fazer, e sim, sempre, opronunciar que é constitutivo do ‘direito’: ius dicereiu-dex nos reconduzem a essa ligação constante. (…) É por intermédio deste ato de fala ius dicere que se desenvolve toda a terminologia da via judiciária: iudex, iudicare, iudicium, iuris-dictio, etc.” Assim, o tipo, a tipificação, é um dos modos pelos quais a linguagem se converte em fórmula. O funcionamento formulário da linguagem no Direito, o afastamento total com a linguagem ordinária, pode ser melhor vista naqueles crimes relacionados justamente à linguagem. Dois exemplos, um da antiguidade e um muito recente podem demonstrar como isso diz respeito à própria lógica do Direito. O primeiro é do famoso orador grego Lísias, que viveu na passagem entre os séculos V e IV a.C. Em seu discurso Contra Theomnestus, Lísias argumenta que a lei contra a calúnia era inócua, na medida em que proibia que se chamasse alguém de “assassino” (androfonon), mas era incapaz de punir aquele que, como Theomnestus, acusava outrem de “matar” (apektonenai) seu pai. O outro caso ocorreu em março de 2010, no Supremo Tribunal Federal. Argumentando contra as cotas, o ex-senador Demóstenes Torres disse que as “negras (escravas) mantinham ‘relações consensuais’ com os brancos (seus patrões)”. Que consensualidade, podemos perguntar, é possível haver entre sujeitos que estão numa relação de senhor e escravo?  Porém, é evidente que nenhum dos 11 magistrados de “reputação ilibada” e “notável saber jurídico” viu racismo aí. Se o argumento tivesse sido enunciado de outra forma (com referência a uma “natural concupiscência” das negras, para dar um exemplo da nefasta tradição racista do Judiciário brasileiro), talvez acarretasse em uma ocorrência jurídica de racismo. Para que algo se inscreva na esfera do Direito, ele precisa se formalizar, ou melhor, se formularizar, se tornar fórmula. Não se trata aqui apenas de inscrição na legislação, em uma lei elaborada pelo Poder Legislativo. O Direito pode existir – e continuar calcado no formalismo – mesmo ali onde não há lei em sentido estrito, o que é provado pelo Direito costumeiro. A formalização é um processo maior do que a lei, e engloba  toda a máquina judiciária, o que inclui juízes, decisões judiciais, advogados, juristas, a chamada “doutrina”, chegando até à sociedade. Trata-se da fixação de conteúdos permitidos ou proibidos em fórmulas, procedimento que, como vimos com os tipos, permite sua reprodução. Esse é o paradoxo do que se costuma chamar, em geral pejorativamente, de “politicamente correto”: ao mesmo tempo que produz avanços materiais inegáveis, está limitado à própria formalidade. Ou seja, as fórmulas – aquilo que (não) se pode fazer ou dizer – repercutem sobre o mundo, modificam o mundo, mas elas não perdem a sua dimensão de fórmulas. Aqueles que defendem o Direito como um mecanismo de transformação social (ou mesmo só como uma ferramenta progressista), mais cedo ou mais tarde esbarram nesse paradoxo: o Direito só garante aquilo que está consubstanciado em fórmulas (e são justamente fórmulas que, por vezes, impedem a transformação social). A partir do momento que se defende o reconhecimento jurídico de certos direitos que o Direito não reconhece, se está defendendo a formalização desses direitos. De fato, a oposição entre direito material e direito formal é inócua: na medida em que a formalização dos direitos é um processo histórico, todo direito formal já foi apenas um direito material, e pode voltar a sê-lo. Ninguém é condenado por emitir discursos de conteúdos racistas (matéria) – só existe o crime de racismo quando este é enunciado de uma certa forma, por uma certa fórmula.

6. Todo jurista conhece a “pirâmide” normativa de Hans Kelsen, em que as normas são ordenadas hierarquicamente (os estratos mais baixos retiram sua validade dos mais altos), e no topo da qual está a “norma fundamental”. O problema, como se sabe, é que essa norma fundamental seria vazia de conteúdo, isto é, pressuposta, imaginária, ficcional (para postular o estatuto da norma fundamental, Kelsen se baseou na Filosofia do como se, de Vaihinger, para o qual até mesmos o discurso científico residia, em última instância, sobre alguma ficção). Ou seja, uma maneira de dar validade ao sistema, de remetê-lo ao Um (ainda que alguns queiram ligá-la ao princípio de que os pactos devem ser cumpridos – pacta sunt servanda –, e outros, muito mais tacanhos, à Constituição). Teríamos, assim, um sistema de normas com conteúdo baseadas numa norma sem conteúdo e fictícia. Talvez, porém, fosse mais produtivo entender o Direito de maneira invertida: um sistema de normas vazias, baseadas numa única norma com conteúdo: o de que a ficção que conhecemos como Direito é verdadeira. No momento histórico atual, poderíamos dizer que tal norma fundamental se cristalizaria em dois princípios: o de que não se pode alegar desconhecimento da lei (fechamento), e o de que o juiz não pode se furtar de decidir uma causa (abertura). Ou seja, o conteúdo da norma fundamental seria o de que o Direito é um sistema, ao mesmo tempo (mas não paradoxalmente), aberto e fechado – o que quer dizer: potencialmente Total. Fechamento e disseminação são conexos no Direito. Para que seja “verdadeiro”, ele não pode assumir seu estatuto de pura linguagem, ou melhor, tem que anulá-lo, dotando toda linguagem de uma potencial “eficácia”. Como as normas e os processos não passam de linguagem sem relação necessária com as coisas, é preciso este princípio que estabelece que alguma relação entre as palavras (normas) e as coisas (fatos) tem que se dar. É desse caráter vazio das normas e dos processos, do seu embasamento na linguagem (e não nas coisas) que deriva a inflação normativa, processo inerente ao Direito. As normas e os processos não passam, no fundo, de fórmulas que se invocam para tentar estabelecer este ou aquele nexo entre as palavras e as coisas – mas todas invocam, como pressuposto, o próprio nome do Direito, isto é, a norma fundamental: a de que a ficção é verdadeira. Portanto, as fórmulas, os tipos, os brocardos, em suma, o juridiquês, são o modo pelo qual se mantém a ficção, e pelo qual a vida, a linguagem comum, é capturada na esfera do Direito, ao mesmo tempo em que é afastada dela.  Nas ficções de Kafka, é comum o confronto, e mesmo o entrelaçamento, entre ficção e direito. O inacabado romance O processo encena bem este confronto e entrelaçamento. Ao início do romance, quando os oficiais da lei vão deter o protagonista K., este imagina se tratar apenas de uma trupe teatral aplicando um trote de aniversário a pedido de amigos. Ao final, quando seus executores chegam para buscá-lo, K. novamente quer acreditar que são apenas de atores encenando e pregando-lhe uma peça. E, de fato, todo o aparato judicial narrado no romance parece ser uma grande ficção: porões obscuros, audiências em cortiços, advogados moribundos. Em nenhum momento aparece a Lei, K. não consegue adentrar a Lei. Em nenhum momento, K. sabe do que está sendo acusado. O romance inteiro é construído sobre a figura dos mediadores – cartorários, advogados, oficiais – que encenam um grandiloqüente e patético processo, uma ficção da qual K. pode a qualquer momento sair. O Direito e o processo são apenas grandes narrativas ficcionais – mas estas encenações, ao contrário das teatrais, tomam vidas. O juridiquês é e não é apenas uma encenação de alguns juristas. É apenas o modo de narrar uma ficção; mas essa ficção atende pelo nome de Direito, que captura e reduz a vida, retirando a sua singularidade e reproduzindo-a como um tipo. Ao “se” da prescrição jurídica, corresponde um “então”. Um “então” que está ausente na verdadeira ficção, que é sempre e apenas um “como se”.

Some Plants Are Altruistic, Too, New Study Suggests (Science Daily)

Feb. 1, 2013 — We’ve all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a study led by the University of Colorado Boulder suggests some plants are altruistic too.

A new study led by CU-Boulder involving graduate student Chi-Chih Wu, shown here, indicates corn plants may have an altruistic side. (Credit: Photo courtesy CU-Boulder)

The researchers looked at corn, in which each fertilized seed contained two “siblings” — an embryo and a corresponding bit of tissue known as endosperm that feeds the embryo as the seed grows, said CU-Boulder Professor Pamela Diggle. They compared the growth and behavior of the embryos and endosperm in seeds sharing the same mother and father with the growth and behavior of embryos and endosperm that had genetically different parents.

“The results indicated embryos with the same mother and father as the endosperm in their seed weighed significantly more than embryos with the same mother but a different father,” said Diggle, a faculty member in CU-Boulder’s ecology and evolutionary biology department. “We found that endosperm that does not share the same father as the embryo does not hand over as much food — it appears to be acting less cooperatively.”

A paper on the subject was published during the week of Jan. 21 in the Proceedings of the National Academy of Sciences. Co-authors on the study included Chi-Chih Wu, a CU-Boulder doctoral student in the ecology and evolutionary biology department and Professor William “Ned” Friedman, a professor at Harvard University who helped conduct research on the project while a faculty member at CU-Boulder.

Diggle said it is fairly clear from previous research that plants can preferentially withhold nutrients from inferior offspring when resources are limited. “Our study is the first to specifically test the idea of cooperation among siblings in plants.”

“One of the most fundamental laws of nature is that if you are going to be an altruist, give it up to your closest relatives,” said Friedman. “Altruism only evolves if the benefactor is a close relative of the beneficiary. When the endosperm gives all of its food to the embryo and then dies, it doesn’t get more altruistic than that.”

In corn reproduction, male flowers at the top of the plants distribute pollen grains two at a time through individual tubes to tiny cobs on the stalks covered by strands known as silks in a process known as double fertilization. When the two pollen grains come in contact with an individual silk, they produce a seed containing an embryo and endosperm. Each embryo results in just a single kernel of corn, said Diggle.

The team took advantage of an extremely rare phenomenon in plants called “hetero-fertilization,” in which two different fathers sire individual corn kernels, said Diggle, currently a visiting professor at Harvard. The manipulation of corn plant genes that has been going on for millennia — resulting in the production of multicolored “Indian corn” cobs of various colors like red, purple, blue and yellow — helped the researchers in assessing the parentage of the kernels, she said.

Wu, who cultivated the corn and harvested more than 100 ears over a three-year period, removed, mapped and weighed every individual kernel out of each cob from the harvests. While the majority of kernels had an endosperm and embryo of the same color — an indication they shared the same mother and father — some had different colors for each, such as a purple outer kernel with yellow embryo.

Wu was searching for such rare kernels — far less than one in 100 — that had two different fathers as a way to assess cooperation between the embryo and endosperm. “It was very challenging and time-consuming research,” said Friedman. “It was like looking for a needle in a haystack, or in this case, a kernel in a silo.”

Endosperm — in the form of corn, rice, wheat and other crops — is critical to humans, providing about 70 percent of calories we consume annually worldwide. “The tissue in the seeds of flowering plants is what feeds the world,” said Friedman, who also directs the Arnold Arboretum at Harvard. “If flowering plants weren’t here, humans wouldn’t be here.”

Brazil’s ‘Poor’ Middle Class, And The Poor That No Longer Serve Them (Forbes)

By Kenneth Rapoza – 1/22/2013 @ 11:41AM |8.546 views

Let me preface this by saying that this is not a jab at Brazil. This is actually a story that shows how Brazil’s rising tide is lifting all boats. The poor have more opportunities than ever before. They are earning more money (for some, how’s 56 percent sound?). And for the middle class that used to depend on them to wash their dishes and make their lunch, those days of luxury are over.

Bemvindo a vida Americana, meu bem!

*       *       *

My “house.” Edificio Bretagne. How I miss it. Right in the fold, top floor, all three windows were mine all mine. And a maid cleaned them for me.

Ask an expat what they love most about living overseas and they will inevitably tell you this: the taxes and the maid service. That’s right. Maids. And not for the rich, mind you, but for middle-of-the-road, beer-from-a-can drinking, 2.5 GPA achieving riff-raff professionals. Whether they’re living in Dubai, Mumbai or Brazil, they all love their maids. It’s a luxury they cannot afford back home.

I lived in Brazil for 10 years. I left in March 2010. Maids cooked my lunch, always a three courser. Rice. Beans, sometimes black, sometimes Carioca-style, which meant brown. Meat. Salad. Desert. Fresh squeezed orange juice or Swiss lemonade. Passion fruit. Guarana. Then, she did my dishes. Afterwards, she washed my clothes and pressed them.

As time went on, maintaining a daily maid became too costly. I cut back. I had a maid just twice a week. She cleaned. She did laundry. I cooked. I paid her R$80 a day, or R$140 a week, which was around $78 for two full days of work. Her name was Hélia. Me and my girls loved Hélia. I hope she is doing well. Anyway…

We lived in this beautiful building pictured here in São Paulo, in the Higienopolis neighborhood. A colleague of mine from one of the big U.S. newswires lived there, too. Our children hung out together a lot, especially in the swimming pool, which was surrounded by palm trees that housed these small green parrots that blended in with the palm leaves. He too had a maid, only his maid was there every day and sometimes on the weekends. A female columnist from Folha de São Paulo newspaper lived in the building, too. She also had a daughter. Only her daughter had a maid and a nanny, seven days a week. This was an early 40-something year old newspaper columnist, not a rock star.

Like me, my colleague was an American living a life we could never afford in the States. Ever. We were both scum sucking reporters waiting for the ax to fall on our necks. He, a little richer and hopeful; me, a little younger and angrier. One thing we all appreciated was being able to afford the extra help.

My swimming pool. We even had a barman. Though he was a grump. Me, my daughter and the daughter of an American reporter colleague called him Mr. Grumpy Pumpkin Man during our Halloween parties. Ahhh, the life…

Over the last 8 years, the income of Brazil’s domestic workers has risen by an estimated 56 percent, according to the Brazilian Institute for Geography and Statistics, IBGE. It’s a hard number to quantify because every single maid in Brazil is paid under the table in cash. By comparison, the average income in general rose by 29 percent. Nationwide, the average salary paid to domestic servants runs around R$721 a month, or around $360. However, that figure is double or triple in big cities like São Paulo and Rio de Janeiro. The income of Brazilian maids has risen by an average of 6.7 percent in just one year in real terms. Adding to the price tag is a steady decline in the number of domestic workers in the market.

Quite frankly, Brazil’s economy is getting richer. The poor have better things to do than clean up after middle class teenagers who still haven’t learned to fold and put away their own  T-shirts.

Short supply, high prices. Many Brazilians cannot afford the help. Welcome to your American Dream, Brazil!

Carol Campos is an administrator at Banco do Brasil in São Paulo. It’s a nice, full-time middle class gig. She lives in Higienopolis. I’ve been to her house many times. Our kids are friends. They went to school together. She used to have a maid every day when her first child was born, then down to a couple days a week and now — because of the rising cost of living — she tells me, “We are now down to just one day per week. It’s too expensive.” She pays her maid R$90 ($45) a day.

A host of new labor laws designed to protect informal workers drove up costs. The government wanted the working poor, most of them women, to have enough money to save for retirement and, of course, healthcare. That started driving up prices around the year 2000.

“About four years ago, when me and my sister were in college and working, my family all decided to just hire a ‘diarista’,” says , Leoberto José Preuss, a systems analyst at Brazilian IT firm TOTVS in Joinville, Santa Catarina, one of the more middle class states in the country.  Back then he says, a diarista, a maid that just comes once in a while and charges a flat day rate, charged just R$60 a day to cook and clean a house. “You’re lucky if you find anyone for less than 90,” he says. “We have someone come three days a week. It’s difficult to find anyone available these days.”

It will get harder. And as time goes on, it will definitely get more costly. So costly, in fact, that the majority of middle class Brazilians will no longer have a maid.

The government recently required full time domestic workers to receive the coveted “thirteenth salary”, a whole month’s work of pay in December, plus workman’s comp through the FGTS tax.  Brazilian maid service is becoming professionalized, and that has pulled the rug out from the middle class that has come to depend on them to keep their house in order.

A poll from Folha de São Paulo this month asked respondents if they would be able to afford a maid given the new labor laws. Out of the 1,177 on line respondents, 44 percent said no, 26 percent said they’d have to cut back on hours. So a total 70 percent are starting to get used to the fact that the good ole “Banana Republic” days are gone.

Sarah Castro, 28, is also from Santa Catarina. She is one of the Brazilian middle class that grew up with a live-in maid, her very own Mary Poppins. For Americans, this is an imperial wet dream.  All that’s missing is Tinkerbell. In the dream, you’re from the rich nation before the days of labor rights, and your family can afford to hire your neighbors wife to clean the house, while he cleans your chimney.  Those days are gone in London. They are ending in Florianopolis, Santa Catarina, where Sarah was raised and now works as a reporter.

“Our maid was named Nice. She lived with us and was part of our family. I miss her. There was no one like her,” she says. “Nowadays, we only have a maid once a week.  A good maid is hard to find.”

Let’s rephrase that. Barring a dystopian future, by the time Sarah is in her 40s, an affordable maid will be impossible to find.

I was in my early 20s when I first came to Brazil in 1995, I lived with a family in a city called Londrina, population around 500,000.  It’s in the center of Parana state, an agribusiness boom town.  The father was a professor at the local university.  The mother owned a small business, operating a clothing company out of what was once their garage. They had one weaving machine that made fabric 24 hours a day, 7 days a week. I can still hear that thing moving back and force, swish-swoosh; swish-swoosh, swish-swoosh. They were Brazil’s middle class. By my standards, they were rich because six days a week they had a maid who cooked and cleaned for them so both parents could work. The maid served them. She picked up after the four children. She cleaned up the dog’s mess in the yard.

Here’s the rub, I was raised by a maid. My mother didn’t graduate from high school. But she grew up in America. A maid that didn’t go to school in Brazil doesn’t live like one that grew up in the U.S.  The Brazilians couldn’t believe that a maid’s son had a basketball pole in his yard, an above ground pool and that my family had three cars. Their car ran on ethanol, and that thing was a piece of junk; a jalopy is more like it. Damn, meu filho; I had aCamaro Berlinetta!

Inequality in Brazil allowed the middle class to enjoy a life of luxury their American peers envied.

I never saw a messy Brazilian house in the decade I lived there. Everything was in its place.  Two-income households in São Paulo, as busy as a two-income household in New York, never had a dish in the sink, an unmade bed, or a laundry basket overflowing onto the bathroom floor.

Embrace the mess, Brazil. (And pick up those socks!)

“I have a maid come once every 15 days and that’s it,” says Keli Bergamo, a lawyer in Parana state. “The cooking, the clothes washing, I have to do myself. But I live alone. I know a lot of people who are cutting back. Brazilians will get crafty with the labor laws, though,” she says, adding that many wealthy Brazilians will avoid the full time labor rules by getting rid of full time maids and hiring part-timers in their place.

“These new laws make it more costly to maintain domestic help in Brazil,” she says. “A lot of people are going to give up this comfort and will have to divide the labor between the members of their household from now on.”

Criminalizing Dissent and Punishing Occupy Protesters: Introduction to Henry Giroux’s “Youth in Revolt” (Truth Out)

Thursday, 31 January 2013 06:22By Henry A GirouxTruthout | Book Excerpt

Military-style command and control systems are now be­ing established to support “zero tolerance” policing and urban surveillance practices designed to exclude failed consumers or undesirable persons from the new enclaves of urban consumption and leisure.

—Stephen Graham

Youth in Revolt.(Image: Paradigm Publishers)

Young people are demonstrating all over the world against a variety of issues ranging from economic injustice and massive inequality to drastic cuts in education and public services.1 In the fall of 2011, on the tenth anniversary of September 11, as the United States revisited the tragic loss and celebrated the courage displayed on that torturous day, another kind of commemoration took place. The Occupy movement shone out like flame in the darkness—a beacon of the irrepressible spirit of democracy and a humane desire for justice. Unfortunately, the peacefully organized protests across America have often been met with derogatory commentaries in the mainstream media and, increasingly, state-sanctioned violence. The war against society has become a war against youthful protesters and in­creasingly bears a striking resemblance to the violence waged against Occupy movement protesters and the violence associ­ated with the contemporary war zone.2 Missing from both the dominant media and state and national politics is an attempt to critically engage the issues the protesters are raising, not to mention any attempt to dialogue with them over their strate­gies, tactics, and political concerns. That many young people have become “a new class of stateless individuals … cast into a threatening and faceless mass whose identities collapse into the language of debt, survival, and disposability” appears to have escaped the attention of the mainstream media.3 Matters of justice, human dignity, and social responsibility have given way to a double gesture that seeks to undercut democratic public spheres through the criminalization of dissent while also resorting to crude and violent forms of punishment as the only mediating tools to use with young people who are at­tempting to open a new conversation about politics, inequality, and social justice.

In the United States, the state monopoly on the use of violence has intensified since the 1980s and in the process has been di­rected disproportionately against young people, poor minorities, immigrants, women, and the elderly. Guided by the notion that unregulated, market-driven values and relations should shape every domain of human life, a business model of governance has eviscerated any viable notion of social responsibility and conscience, thereby furthering the dismissal of social problems and expanding cutbacks in basic social services.4 The examples are endless, but one in particular stands out. In March 2012, Texas governor Rick Perry7joined eight other states in passing legislation to ban funding for clinics, including Planned Parent­hood facilities, affiliated with abortion services for women.5 As a result, the federal government has stopped funding the Texas Women’s Health Program. Unfortunately, this attempt by Perry to punish all women because of his antiabortion stance means that more than 130,000 women in Texas will not have access to vital services ranging from mammograms to health care for their children. There is more at work here than a resurgent war on women and their children or “an insane bout of mass misogyny.”8 There is also a deep-seated religious and political authoritarianism that has become one of the fundamental pil­lars of what I call a neoliberal culture of cruelty. As the welfare state is hollowed out. a culture of compassion is replaced by a culture of violence, cruelty, waste, and disposability.7Banks, hedge funds, and finance capital as the contemporary registers of class power have a new visibility, and their spokespersons are unabashedly blunt in supporting a corporate culture in which “ruthlessness is prized and money is the ultimate measure.”Collective insurance policies and social protections have given way to the forces of economic deregulation, the transformation of the welfare state into punitive workfare programs, the privatiza­tion of public goods, and an appeal to individual culpability as a substitute for civic responsibility. At the same time, violence—or what Anne-Marie Cusac calls “American punishment”—travels from our prisons and schools to various aspects of our daily lives, “becoming omnipresent … [from] the shows we watch on television, [to] the way many of us treat children [to] some influential religious practices.”9

David Harvey has argued that neoliberalism is “a political proj­ect to re-establish the conditions for capital accumulation and to restore the power of economic elites” through the implementation of “an institutional framework characterized by strong private property rights, free markets, and free trade.”10 Neoliberalism is also a pedagogical project designed to create particular subjects, desires, and values defined largely by market considerations. National destiny becomes linked to a market-driven logic in which freedom is stripped down to freedom from government regulation, freedom to consume, and freedom to say anything one wants, regardless of how racist or toxic the consequences might be. This neoliberal notion of freedom is abstracted from any sense of civic responsibility or social cost. In fact, “neoliberalism is grounded in the idea of the ‘free, possessive individual,'” with the state cast “as tyrannical and oppressive.”11 The welfare state, in particular, becomes the archenemy of freedom. As Stuart Hall points out, according to apostles of free-market fundamentalism, ‘The state must never govern society, dictate to free individuals how to dispose of their private property, regulate a free-market economy or interfere with the God-given right to make profits and amass personal wealth.”12

Paradoxically, neoliberalism severely proscribes any vestige of social and civic agency through the figure of the isolated automaton for whom choice is reduced to the practice of end­less shopping, fleeing from any sense of civic obligation, and safeguarding a radically individualized existence. Neoliberal governance translates into a state that attempts to substitute individual security for social welfare but in doing so offers only the protection of gated communities for the privileged and incarceration for those considered flawed consumers or threats to the mythic ideal of a white Christian nation. Neoliberalism refuses to recognize how private troubles are connected to broader systemic issues, legitimating instead an ode to self-reliance in which the experience of personal misfortune becomes merely the just desserts delivered by the righteous hand of the free market—not a pernicious outcome of the social order being hijacked by an antisocial ruling elite and forced to serve a narrow set of interests. Critical thought and human agency are rendered impotent as neoliberal rationality “substitutes emotional and personal vocabularies for political ones in formulating solutions to political problems.”13 Within such a depoliticized discourse, youths are told that there is no dream of the collective, no viable social bonds, only the ac­tions of autonomous individuals who must rely on their own resources and who bear sole responsibility for the effects of larger systemic political and economic problems.

Under the regime of neoliberalism, no claims are recognized that call for compassion, justice, and social responsibility. No claims are recognized that demand youths have a future better than the present, and no claims are recognized in which young people assert the need to narrate themselves as part of a broader struggle for global justice and radical democracy. Parading as a species of democracy, neoliberal economics and ideology cancel out democracy “as the incommensurable sharing of existence that makes the political possible.”14 Symptoms of ethical, politi­cal, and economic impoverishment are all around us. And, as if that were not enough, at the current moment in history we are witnessing the merging of violence and governance along with a systemic disinvestment in and breakdown of institutions and public spheres that have provided the minimal conditions for democracy and the principles of communal responsibil­ity. Young people are particularly vulnerable. As Jean-Marie Durand points out, “Youth is no longer considered the world’s future, but as a threat to its present. [For] youth, there is no longer any political discourse except for a disciplinary one.”13

As young people make diverse claims on the promise of a radical democracy in the streets, on campuses, and at other occupied sites, articulating what a fair and just world might be, they are treated as criminal populations—rogue groups incapable of toeing the line, “prone to irrational, intemperate and unpredictable” behavior.16Moreover, they are increasingly subjected to orchestrated modes of control and containment, if not police violence. Such youths are now viewed as the enemy by the political and corporate establishment because they make visible the repressed images of the common good and the impor­tance of democratic public spheres, public services, the social state, and a society shaped by democratic values rather than market values. Youthful protesters and others are reclaiming the repressed memories of the Good Society and a social state that once, as Zygmunt Bauman has pointed out, “endorsed collective insurance against individual misfortune and its consequences.”17 Bauman explains that such a state “lifts members of society to the status of citizens—that is, makes them stake-holders in addition to being stock-holders, beneficiaries but also actors responsible for the benefits’ creation and availability, individuals with acute interest in the common good understood as the shared institutions that can be trusted to assure solidity and reliability of the state-issued ‘collective insurance policy.'”18 In an attempt to excavate the repressed memories of the welfare state, David Theo Goldberg spells out in detail the specific mechanisms and policies it produced in the name of the general welfare between the 1930s and 1970s in the United States. He writes,

From the 1930s through the 1970s, the liberal democratic state had offered a more or less robust set of institutional appara­tuses concerned in principle at least to advance the welfare of its citizens. This was the period of advancing social security, welfare safety nets, various forms of national health system, the expansion of and investment in public education, including higher education, in some states to the exclusion of private and religiously sponsored educational institutions. It saw the emer­gence of state bureaucracies as major employers especially in later years of historically excluded groups. And all this, in turn, offered optimism among a growing proportion of the populace for access to middle-class amenities, including those previously racially excluded within the state and new immigrants from the global south.19

Young people today are protesting against a strengthening global capitalist project that erases the benefits of the welfare state and the possibility of a radical notion of democracy. They are protesting against a neoliberal project of accumulation, dispossession, deregulation, privatization, and commodification that leaves them out of any viable notion of the future. They are rejecting and resisting a form of casino capitalism that has ushered in a permanent revolution marked by a massive project of depoliticization, on the one hand, and an aggressive, if not savage, practice of distributing upward wealth, income, and op­portunity for the 1 percent on the other. Under neoliberalism, every moment, space, practice, and social relation offers the possibility of financial investment, or what Ernst Bloch once called the “swindle of fulfillment.”20 Goods, services, and targeted human beings are ingested into its waste machine and dismissed and disposed of as excess. Flawed consumers are now assigned the status of damaged and defective human beings. Resistance to such oppressive policies and practices does not come easily, and many young people are paying a price for such resistance. According to OccupyArrests.com, “there have been at least 6705 arrests in over 112 different cities as of March 6, 2012.”21

Occupy movement protests and state-sponsored violence “have become a mirror”—and I would add a defining feature—”of the contemporary state.”22 Abandoned by the existing political system, young people in Oakland, California, New York City, and numerous other cities have placed their bodies on the line, protesting peacefully while trying to produce a new language, politics, and “community that manifests the values of equality and mutual respect that they see missing in a world that is structured by neoliberal principles.”23 Well aware that the spaces, sites, and spheres for the representation of their voices, desires, and concerns have collapsed, they have occupied a number of spaces ranging from public parks to college campuses in an effort to create a public forum where they can narrate themselves and their visions of the future while representing the misfortunes, suffering, and hopes of the unemployed, poor, incarcerated, and marginalized. This movement is not simply about reclaiming space but also about producing new ideas, generating a new conversation, and introducing a new political language.

Rejecting the notion that democracy and markets are the same, young people are calling for the termination of corporate control over the commanding institutions of politics, culture, and economics, an end to the suppression of dissent, and a shutting down of the permanent warfare state. Richard Lichtman is right to insist that the Occupy movement should be praised for its embrace of communal democracy as well as an emerging set of shared concerns, principles, and values articulated “by a demand for equality, or, at the very least, for a significant lessening of the horrid extent of inequality; for a working democracy; for the elimination of the moneyed foun­dation of politics; for the abolition of political domination by a dehumanized plutocracy; for the replacement of ubiquitous commodification by the reciprocal recognition of humanity in the actions of its agents.”24 As Arundhati Roy points out, what connects the protests in the United States to resistance move­ments all over the globe is that young people “know that their being excluded from the obscene amassing of wealth of U.S. corporations is part of the same system of the exclusion and war that is being waged by these corporations in places like India, Africa, and the Middle East.”25 Of course, Lichtman, Roy, and others believe that this is just the beginning of a movement and that much needs to be done, as Staughton Lynd argues, to build new strategies, a vast network of new institutions and public spheres, a community of trust, and political organiza­tion that invites poor people into its ranks.26 Stanley Aronowitz goes further and insists that the Occupy movement needs to bring together the fight for economic equality and security with the task of reshaping American institutions along genuinely democratic lines.27

All of these issues are important, but what must be addressed in the most immediate sense is the danger the emerging police state in the United States poses not just to the young protesters occupying a number of American cities but to democracy itself. This threat is particularly evident in the results of a merging of neoliberal modes of discipline and education with a warlike mentality in which it becomes nearly impossible to reclaim the language of obligation, compassion, community, social re­sponsibility, and civic engagement. And unless the actions of young protesters, however diverse they may be, are understood alongside a robust notion of the social, civic courage, com­munal bonds, and the imperatives of a vital democracy, it will be difficult for the American public to challenge state violence and the framing of protest, dissent, and civic engagement as un-American or, worse, as a species of criminal behavior.

Although considerable coverage has been given in the pro­gressive media to the violence being waged against the Occupy protesters, these analyses rarely go far enough. I want to build on these critiques by arguing that it is important to situate the growing police violence within a broader set of categories that both enables a critical understanding of the underlying social, economic, and political forces at work in such assaults and al­lows us to reflect critically on the distinctiveness of the current historical period in which they are taking place. For example, it is difficult to address such state-sponsored violence against young people and the Occupy movement without analyzing the devolution of the social state and the corresponding rise of the warfare and punishing state.’2b The notion of historical conjunc­ture is important here because it both provides an opening into the diverse forces shaping a particular moment and allows for a productive balance of theory and strategy to inform future interventions. That is. it helps us to address theoretically how youth protests are largely related to and might resist a histori­cally specific neoliberal project that promotes vast inequalities in income and wealth, creates the student-loan debt bomb, eliminates much-needed social programs, privileges profits and commodities over people, and eviscerates the social wage.

Within the United States, the often violent response to non­violent forms of youth protest must also be analyzed within the framework of a mammoth military-industrial state and its commitment to war and the militarization of the entire society. The merging of the military-industrial complex and unchecked finance capital points to the need for strategies that address what is specific about the current warfare state and the neo­liberal project that legitimates it. That is, what are the diverse practices, interests, modes of power, social relations, public pedagogies, and economic configurations that shape the poli­tics of the punishing state? Focusing on the specifics of the current historical conjuncture is invaluable politically in that such an approach makes visible the ideologies, policies, and modes of governance produced by the neoliberal warfare state. When neoliberal mechanisms of power and ideology are made visible, it becomes easier for the American public to challenge the common assumptions that legitimate these apparatuses of power. This type of interrogative strategy also reclaims the necessity of critical thought, civic engagement, and democratic politics by invoking the pedagogical imperative that humans not only make history but can alter its course and future direction.

For many young people today, human agency is denned as a mode of self-reflection and critical social engagement rather than a surrender to a paralyzing and unchallengeable fate. Likewise, democratic expression has become fundamental to their existence. Many young people are embracing democracy not merely as a mode of governance, but more importantly, as Bill Moyers points out, as a means of dignifying people “so they become fully free to claim their moral and political agency.”29 Human agency has become a vital force to struggle over as part of an ongoing project in which the future remains an open horizon that cannot be dismissed through appeals to the end of history or end of ideology.30 But to understand how politics refuses any guarantees and resistance becomes possible, we must first understand the present. Following Stuart Hall. I want to argue that the current historical moment, or what he calls the “long march of the Neoliberal Revolution,”31 has to be understood not only through the emergent power of finance capital and its institutions but also in terms of the growing forms of authoritarian violence that it deploys and reinforces. I want to address these antidemocratic pressures and their relationship to the rising protests of young people in the United States and abroad through the lens of two interrelated crises: the crisis of governing through violence and the crisis of what Alex Honneth has called “a failed sociality”32—which currently conjoin as a driving force to dismantle any viable notion of public pedagogy and civic education. If we are not to fall prey to a third crisis—”the crisis of negation”33—then it is imperative that we recognize the hope symbolized and embodied by young people across America and their attempt to remake society in order to ensure a better, more democratic future for us all.

The Crisis of Governing through Violence

The United States is addicted to violence, and this dependency is fueled increasingly by its willingness to wage war at home and abroad.34 As Andrew Bacevich rightly argues, “war has be­come a normal condition [matched by] Washington’s seemingly irrevocable abandonment of any semblance of self-restraint regarding the use of violence as an instrument of statecraft.”35 But war in this instance is not merely the outgrowth of policies designed ‘to protect the security- and well-being of the United States. It is also, as C. Wright Mills pointed out. part of a “mili­tary metaphysics”36—a complex of forces that includes corpora­tions, defense industries, politicians, financial institutions, and universities. The culture of war provides jobs, profits, political payoffs, research funds, and forms of political and economic power that reach into every aspect of society. War is also one of the nation’s most honored virtues. Its militaristic values now bear down on almost every aspect of American life.37 Similarly, as the governing-through-violence complex becomes normalized in the broader society, it continually works in a variety of ways to erode any distinction between war and peace.

Increasingly stoked by a moral arnd political hysteria, war­like values produce and endorse shared fears and organized violence as the primary registers of social relations. The con­ceptual merging of war and violence is evident in the ways in which the language of militarization is now used by politicians to address a range of policies as if they are operating on a battlefield or in a war zone. War becomes the adjective of choice as policymakers talk about waging war on drugs, poverty, and the underclass. There is more at work here than the prevalence of armed knowledge and a militarized discourse; there is also the emergence of a militarized society in which “the range of acceptable opinion inevitably shrinks.”38 And this choice of vocabulary and slow narrowing of democratic vision further enable the use of violence as an instrument of domestic policy.

How else to explain that the United States has become the punishing state par excellence, as indicated by the hideous fact that while it contains “5 percent of the Earth’s population, it is home to nearly a quarter of its prisoners”?39 Senator Lindsay Graham made this very clear in his rhetorical justification of the 2012 National Defense Authorization Act by stating “that under this Act the U.S. homeland is considered a ‘battlefield.'”40 The ominous implications behind this statement, especially for Oc­cupy movement protesters, became obvious in light of the fact that the act gives the US government the right to detain “U.S. citizens indefinitely without charge or trial if deemed necessary by the president…. Detentions can follow mere membership, past or present, in ‘suspect organizations.'”41

Since 9/11, the war on terror and the campaign for home­land security have increasingly mimicked the tactics of the enemies they sought to crush and as such have become a war on democracy. A new military urbanism has taken root the United States as state surveillance projects proliferate, signaling what Stephen Graham calls “the startling militariza­tion of civil society—the extension of military ideas of tracking, identification, and targeting into the quotidian spaces and circulations of everyday life.”42 This is partly evident in the ongoing militarization of police departments throughout the United States. Baton-wielding cops are now being supplied with the latest military equipment imported straight from the war zones of Iraq and Afghanistan. Military technologies once used exclusively on the battlefield are now being supplied to police units across the nation: drones, machine-gun-equipped armored trucks, SWAT-type vehicles, “digital communications equipment, and Kevlar helmets, like those used by soldiers used in foreign wars.”43The domestic war against “terrorists” (code for young protesters) provides new opportunities for major defense contractors and corporations to become “more a part of our domestic lives.”44 As Glenn Greenwald points out, the United States since 9/11

has aggressively paramilitarized the nation’s domestic police forces by lavishing them with countless military-style weapons and other war-like technologies, training them in war-zone mili­tary tactics, and generally imposing a war mentality on them. Arming domestic police forces with paramilitary weaponry will ensure their systematic use even in the absence of a terrorist attack on U.S. soil; they will simply find other, increasingly permissive uses for those weapons.45

These domestic paramilitary forces also undermine free speech and dissent through the sheer threat of violence while often wielding power that runs roughshod over civil liberties, human rights, and civic responsibilities.46 Given that “by age 23, almost a third of Americans are arrested for a crime,” it is not unreason­able to assume that in the new militarized state the perception of young people as predators, threats to corporate governance, and disposable objects will intensify, as will the growth of a punish­ing state that acts out against young protesters in increasingly unrestrained and savage ways.47 Young people, particularly poor minorities of color, have already become the targets of what David Theo Goldberg calls “extraordinary power in the name of securitization … [viewed as] unruly populations … [who] are to be subjected to necropolitical discipline through the threat of imprisonment or death, physical or social.”4

Shared fears and the media hysteria that promotes them pro­duce more than a culture of suspects and unbridled intimidation. Fear on a broad public scale serves the interests of policymakers who support a growing militarization of the police along with the corporations that supply high-tech scanners, surveillance cameras, riot extinguishers, and toxic chemicals—all of which are increasingly used with impunity on anyone who engages in peaceful protests against the warfare and corporate state.49 Im­ages abound in the mainstream media of such abuses. There is the now famous image of an eighty-four-year-old woman looking straight into a camera, her face drenched in a liquid spray used by the police after attending a protest rally. There is the image of a woman who is two months pregnant being carried to safety after being pepper-sprayed by the police. By now, the images of young people being dragged by their hair across a street to a waiting police van have become all too familiar.50 Some protesters have been seriously hurt, as in the case of Scott Olsen. an Iraq War veteran who was critically injured in a protest in Oakland in October 2011. Too much of this violence is reminiscent of the violence used against civil rights demonstrators by the enforcers of Jim Crow in the 1950s and 1960s.51

No longer restricted to a particular military ideology, the celebration and permeation of warlike values throughout the culture have hastened the militarization of the entire society. As Michael Geyer points out, militarization can be defined as “the contradictory and tense social process in which civil society organizes itself for the production of violence.”52 As the late Tony Judt put it, “The United States is becoming not just a militarized state but a military society: a country where armed power is the measure of national greatness, and war, or planning for war, is the exemplary (and only) common project.”55 But the prevailing intensification of American society’s permanent war status does more than embrace a set of unifying symbols that promote a survival-of-the-fittest ethic, conformity over dissent, the strong over the weak, and fear over responsibility. Such a move also gives rise to a “failed sociality” in which violence becomes the most important tool of power and the mediating force in shaping social relationships.

A state that embraces a policy of permanent war needs willing subjects to abide by its values, ideology, and narratives of fear and violence. Such legitimation is largely provided through people’s immersion in a market-driven society that appears increasingly addicted to consumerism, militarism, and the spectacles of violence endlessly circulated through popular culture.54 Examples of the violent fare on offer extend from the realm of high fashion and Hollywood movies to extreme sports, video games, and music concerts sponsored by the Pentagon.55 The market-driven celebration of a militaristic mind-set de­mands a culture of conformity, quiet intellectuals, and a largely passive republic of consumers. It also needs subjects who find intense pleasure in spectacles of violence.56

In a society saturated with hyperviolence and spectacular representations of cruelty, it becomes more difficult for the American public to respond politically and ethically to the violence as it is actually happening on the ground. In this in­stance, previously unfamiliar violence such as extreme images of torture and death become banally familiar, while familiar violence that occurs daily is barely recognized, relegated to the realm of the unnoticed and unnoticeable. How else to explain the public indifference to the violence inflicted on nonviolent youth protesters who are raising their voices against a state in which they have been excluded from any claim on hope, pros­perity, and democracy? While an increasing volume of brutal­ity is pumped into the culture, yesterday’s spine-chilling and nerve-wrenching displays of violence lose their shock value. As the demand for more intense images of violence accumulates, the moral indifference and desensitization to violence grow, while matters of savage cruelty and suffering are offered up as fodder for sports, entertainment, news media, and other pleasure-seeking outlets.

As American culture is more and more marked by exag­gerated aggression and a virulent notion of hard masculinity, state violence—particularly the use of torture, abductions, and targeted assassinations—wins public support and requires little or no justification as US exceptionalism becomes accepted by many Americans as a matter of common sense.57 The social impacts of a “political culture of hyper punitiveness”58 can be seen in how structures of discipline and punishment have in­filtrated the social order like a highly charged electric current. For example, the growing taste for violence can be seen in the criminalization of behaviors such as homelessness that once elicited compassion and social protection. We throw the home­less in jail instead of building houses, just as we increasingly send poor, semiliterate students to jail instead of providing them with a decent education. Similarly, instead of creating jobs for the unemployed, we allow banks to foreclose on their mortgages and in some cases put jobless people in debtors’ prisons. The prison in the twenty-first century7 becomes a way of making the effects of ruthless power invisible by making the victims of such power disappear. As Angela Davis points out, “According to this logic the prison becomes a way of disappearing people in the false hope of disappearing the underlying social problems they represent.”39 As the notion of the social is emptied out. criminality is now defined as an essential part of a person’s identity. As a rhetoric of punishment gains ground in American society, social problems are reduced to character flaws, insuf­ficient morality, or a eugenicist notion of being “born evil.”60

Another symptomatic example of the way in which violence has saturated everyday life and produced a “failed sociality” can be seen in the growing acceptance by the American pub­lic of modeling public schools after prisons and criminalizing the behavior of young people in public schools. Incidents that were traditionally handled by teachers, guidance counselors, and school administrators are now dealt with by the police and the criminal justice system. The consequences have been disastrous for young people. Not only do schools increasingly resemble the culture of prisons, but young children are being arrested and subjected to court appearances for behaviors that can only be called trivial. How else to explain the case of the five-year-old student in Florida who was put in handcuffs and taken to the local jail because she had a temper tantrum, or the case of Alexa Gonzales in New York, who was arrested for doodling on her desk? Or twelve-year-old Sarah Bustamatenes, who was pulled from a Texas classroom, charged with a crimi­nal misdemeanor, and hauled into court because she sprayed perfume on herself?61 How do we explain the arrest of a thirteen-year-old student in a Maryland school for refusing to say the pledge of allegiance?62 Or the case of a sixteen-year-old student with an IQ below 70 being pepper-sprayed because he did not understand a question asked by the police officer in his school? After being pepper-sprayed, the startled youth started swinging his arms and for that was charged with two counts of assault on a public servant and faces a possible prison sentence .63 In

The most extreme cases, children have been beaten, Tasered, and killed by the police.

These examples may still be unusual enough to shock, though they are becoming more commonplace. What must be recognized is that too many schools have become combat zones in which students are routinely subjected to metal detectors, surveillance cameras, uniformed security guards, weapons searches, and in some cases SWAT raids and police dogs sniffing for drugs.64 Under such circumstances, the purpose of school­ing becomes to contain and punish young people, especially those marginalized by race and class, rather than educate them. “Arrests and police interactions … disproportionately affect low-income schools with large African-American and Latino populations.”65 For the many disadvantaged students being funnelled into the “school-to-prison pipeline,” schools ensure that their futures look grim indeed as their educational experiences acclimatize them to forms of carceral treatment.66 There is more at work here than a flight from responsibility on the part of educators, parents, and politicians who support and maintain policies that fuel this expanding edifice of law enforce­ment against youth. Underlying the repeated decisions to turn away from helping young people is the growing sentiment that youths, particularly minorities of color and class, constitute a threat to adults and the only effective way to deal with them is to subject them to mind-crushing punishment. Students being miseducated, criminalized, and arrested through a form of pe­nal pedagogy in prison-type schools provides a grave reminder of the degree to which the ethos of containment and punishment now creeps into spheres of everyday life that were largely im­mune in the past to this type of state and institutional violence.

The era of failed sociality that Americans now inhabit reminds us that we live in a time that breaks young people, devalues justice, and saturates the minute details of everyday life with the constant threat, if not reality, of violence. The medieval turn to embracing forms of punishment that inflict pain on the psyches and bodies of young people is part of a larger immersion of society in public spectacles of violence. The control society67 is now the ultimate form of entertainment in America, as the pain of others, especially those considered disposable and pow­erless, is no longer a subject of compassion but one of ridicule and amusement. High-octane violence and human suffering are now considered consumer entertainment products designed to raise the collective pleasure quotient. Brute force and savage killing replayed over and over in the culture function as part of an anti-immune system that turns the economy of genuine pleasure into a mode of sadism that saps democracy of any political substance and moral vitality, even as the body politic appears engaged in a process of cannibalizing its own young. It is perhaps not far-fetched to imagine a reality TV show in which millions tune in to watch young kids being handcuffed, arrested, tried in the courts, and sent to juvenile detention centers. No society can make a claim to being a democracy as long as it defines itself through shared hatred and fears rather than shared responsibilities.

In the United States, society has been reconfigured to eliminate many young people’s access to the minimal condi­tions required for living a full, dignified, and productive life as well as the conditions necessary for sustaining and nurturing democratic structures and ideologies. The cruelty and violence infecting the culture are both a symptom and a cause of our collective failure to mobilize large-scale collective resistance against a growing police state and the massive suffering caused by the savagery of neoliberal capitalism. Unfortunately, even as expressions of authentic rage against Wall Street continue in the Occupy movement, the widespread hardship that young people and other marginalized populations face today “has not found resonance in the public space of articulation. “fs With the collapse of a market economy into a market society, democracy no longer makes a claim on the importance of the common good. As a mode of diseased sociality, the current version of market fundamentalism has turned the principle of freedom against itself, deforming a collective vision of democracy and social justice that once made equality a viable economic idea and political goal in the pursuit of one’s own freedom and civil liberties. As Zygmunt Bauman insists, one of the consequences of this market-driven sovereignty is “the progressive decomposi­tion and crumbling of social bonds and communal cohesion.”6

Neoliberalism creates a language of social magic in which the social either vaporizes into thin air or is utterly pathologized. Shared realities and effects of poverty, racism, inequality, and financial corruption disappear, but not the ideological and institutional mechanisms that make such scourges possible.70 And when the social is invoked favorably, the invocation is only ever used to recognize the claims and values of corporations, the ultrarich, banks, hedgefund managers, and other privileged groups comprising the 1 percent. Self-reliance and the image of the self-made man cancel out any viable notion of social relations, the common good, public values, and collective struggle.

The Occupy movements have recognized that what erodes under such conditions is not only an acknowledgment of the historical contexts, social and economic formations, relations of power, and systemic forms of discrimination that have pro­duced massive inequalities in wealth, income, and opportunity but also any claim to the promise of a substantive democracy. Increasingly, as both the public pedagogy and economic dic­tates of neoliberalism are contested by the Occupiers, the state responds with violence. But the challenges to militarism, in­equality, and political corruption with which young people have confronted American society are being met with a violence that encompasses more than isolated incidents of police brutality. It is a violence emanating from an ongoing wholesale transfor­mation of the United States into a warfare state, from a state that once embraced the social contract—at least minimally—to one that no longer has even a language for community, a state in which the bonds of fear and commodification have replaced the bonds of civic responsibility and democratic commitment. As a result, violence on the part of the state and corporations is not aimed just at youthful protesters. Through a range of visible and invisible mechanisms, an ever-expanding multitude of individuals and populations has been caught in a web of cruelty, dispossession, exclusion, and exploitation.

The predominance of violence in all aspects of social life suggests that young people and others marginalized by class, race, and ethnicity have been abandoned as American soci­ety’s claim on democracy gives way to the forces of militarism, market fundamentalism, and state terrorism. We must ad­dress how a metaphysics of war and violence has taken hold of American society, and the savage social costs it has entailed.

It is these very forms of social, political, and economic violence that young people have recognized and endured against their own minds and bodies, but they are using their indignation to inspire action rather than despair. The spreading imprint of violence throughout society suggests the need for a politics that riot only critiques the established order but imagines a new one—one informed by a radical vision in which the future does not imitate the present. Critique must emerge alongside a sense of realistic hope, and individual struggles must merge into larger social movements.

Occupy Wall Street surfaced in the wake of the 9/11 memori­als and global economic devastation rooted in market deregu­lation and financial corruption. It also developed in response to atrocities committed by the US military in the name of the war on terror, violent and racist extremism spreading through US politics and popular culture, a growing regime of discipline and punishment aimed at marginalized youth, retrograde edu­cation policies destructive of knowledge and critical learning, and the enactment of ruthless austerity policies that serve only to increase human suffering. With the democratic horizon in the United States increasingly darkened by the shadows of a looming authoritarianism and unprecedented levels of social and economic inequality, the Occupy movement and other global movements signify hope and renewal. The power of these movements to educate and act for change should not be under­estimated, particularly among youths, even as we collectively bear witness to the violent retaliation of official power against democratic protesters and the growing fury of the punishing state. In the book that follows, I present chapters that move from negation to hope, from critique to imagining otherwise in order to act otherwise.

The first chapter provides a retrospective on 9/11 that ac­knowledges the way in which the tragic events of 2001 were used to unleash brutal violence on a global scale and legitimate the expansion of the warfare state and unthinkable forms of torture against populations increasingly deemed disposable. In particular, the traumatic aftermath of 9/11 in the United States was distorted into a culture of fear: heightened domes­tic security; and accelerated disciplinary forces that targeted youth, particularly the most vulnerable marginalized by race and class, as potential threats to the social order. This chapter exposes some of the widespread impacts of an unchecked pun­ishing state and its apparatuses—most notably the escalating war on youth, the attack on the social state, and the growth of a “governing through crime” complex—while also paying tribute to the resilience and humanity of the victims of the 9/11 at­tacks and their families. It asserts that public recollection in the aftermath of those traumatic events—particularly the sense of common purpose and civic commitment that ensued—should serve as a source of collective hope for a different future than the one we have seen on display since September 2001.71

Chapter 2 discusses in further detail the cultural shift in the United States that has led to the inscription and normalization of cruelty and violence. In spring 2011, the role of the domi­nant media in sanctioning this culture of cruelty extended to its failure to provide a critical response when the “Kill Team” photographs were released. Even as young people around the world demonstrated against military power and authoritarian regimes, soldiers in the US military fighting in the “war on ter­ror” gleefully participated in horrifying injustices inflicted upon helpless others. The “Kill Team” photos—images of US soldiers smiling and posing with dead Afghan civilians and their des­ecrated bodies—serve as but one example signaling a broader shift in American culture away from compassion for the suffer­ing of other human beings toward a militarization of the culture and a sadistic pleasure in violent spectacles of pain and torture. Further discussion of American popular culture demonstrates how US society increasingly manifests a “depravity of aesthetics” through eagerly consuming displays of aggression, brutality, and death. Connecting this culture of cruelty to the growing influence of neoliberal policies across all sectors, I suggest that this disturbing new enjoyment of the humiliation of others—far from representing an individualized pathology—now infects US society as a whole in a way that portends the demise of the social state, if not any vestige of a real and substantive democ­racy. Recognizing the power of dominant culture to shape our thoughts, identities, and desires, we must struggle to uncover “instants of truth” that draw upon our compassion for others and rupture the hardened order of reality constructed by the media and other dominant cultural forces.

The third chapter suggests that even as US popular culture increasingly circulates images of mind-crushing brutality, American political culture in a similar fashion now functions like a theater of cruelty in which spectacles and public policies display gratuitous and unthinking violence toward the most vulnerable groups in the country, especially children. Despite persistent characterizations of terrorists as “other,” the greatest threat to US security lies in homegrown, right-wing extremism of a kind similar to that espoused by Anders Behring Breivik who in July 2011 bombed government buildings in Oslo, kill­ing eight people, and then went on a murderous shooting rampage in Norway, killing sixty-nine youths attending a Labor Party camp. The eruption of violent speech and racist rhetoric within US political discourse indicates a growing tolerance at the highest levels of government of extremist elements and the authoritarian views and racist hatred they deploy to advance their agenda—which includes dismantling the social state, legitimating a governing apparatus based on fear and punish­ment, undermining critical thought and education through ap­peals to conformity and authoritarian populism, and disposing of all populations deemed dangerous and threatening to the dominance of a white conservative nationalism. Bespeaking far more than a disturbing turn in US politics and the broader cul­ture, right-wing policymakers abetted by the dominant media are waging a campaign of domestic terrorism against children, the poor, and other vulnerable groups as part of a larger war against democracy and the democratic formative culture on which it depends for survival.

Continuing an exploration of the neoliberal mode of authori­tarianism that has infiltrated US politics, Chapter 4 discusses how anti-immigrant and racist political ideology couched in a discourse of patriotism is being translated into regressive educational policies and an attack on critical education. Remi­niscent of the book burnings conducted in Nazi Germany, the Arizona state legislature and school board in Tucson have systematically eliminated ethnic studies from elementary schools and banned books that: discuss racism and oppres­sion, including several books by Mexican American authors in a school district where more than 60 percent of the students are from a Mexican American background. Within a neoliberal regime that supports corporate hegemony, social and economic inequality, and antidemocratic forms of governance, racism is either privatized by encouraging individual solutions to socially produced problems or disavowed, appearing instead in the guise of a language of punishment that persecutes anyone who even raises the specter of ongoing racism. The censorship of ethnic studies in Arizona and of forms of pedagogy that give voice to oppression points to how ideas that engage people in a struggle for equality and democracy pose a threat to fundamentalist ideologues and their war against the bodies, histories, and modes of knowledge that could produce the critical conscious­ness and civic courage necessary for a just society.

Chapter 5 examines the politics of austerity in terms of how it releases corporations and the rich from responsibility for the global economic recession and instead inflicts vast amounts of pain and suffering upon the most vulnerable in society. As an extension of the culture of cruelty, austerity measures encode a fear and contempt for social and economic equality, leading not only to the weakening of social protections and tax breaks for the wealthy but also to the criminalization of social prob­lems. Austerity as a form of “trickle-down cruelty” symbolizes much more than neglect—it suggests a new mode of violence mobilized to address pervasive social ills that will only serve to hasten the emergence of punishing states and networks of global violence. Hope for preventing the escalation of human suffering must be situated in a concerted effort both to raise awareness about the damage wreaked by unchecked casino capitalism and to rethink the very nature of what democracy means and might look like in the United States. A capacity for critical thought, compassion, and informed judgment needs to be nurtured against the forms of bigotry, omission, and social irresponsibility that appear increasingly not only to sanction but also to revel in horror stories of inhumanity and destruc­tion.

Tracing the trajectory of class struggle and inequality in America up to the present day, Chapter 6 argues that a grow­ing concentration of wealth in the hands of the ruling elite means that the political system and mode of governance in the United States are no longer democratic, even as state power is subordinated to the interests of corporate sovereignty. In this chapter, an account of the political, social, and economic injus­tices confronting the vast majority of Americans—the result of a decades-long unchecked supremacy of corporate power, the reign of corrupt financiers, and a ruthless attack on the social state and social protections—sets the stage for what emerged as the Occupy Wall Street movement in September 2011. While making visible the ongoing significance of class as a political category, the Occupiers did much more than rehash the tired rhetoric of “class warfare” (marshaled by their opponents in an effort to position the ruling elites as victims of class resentment) Quite to the contrary, the Occupiers revealed the potential for a broad collective movement both to expose the material realities of inequality and injustice and to counter prevailing antidemocratic narratives while also fundamentally changing the terms of engagement by producing new images, stories, and memories that challenged the complacency of the public and the impoverished imagination of political and corporate leadership in America.

Chapter 7 concludes the book by reviewing the impact and legacy of the Occupy movement, particularly how it exposed the many ways in which US society has mortgaged the future of youth. The Occupiers have become the new public intellectu­als, and they are creating a newpedagogy and politics firmly rooted in democracy, social justice, and human dignity that increasingly occupies the terrain of public discourse and poses a fundamental challenge to the control of the public sphere by corporate elites and their teaching machines. At risk of losing ideological dominance, the authorities retaliated against Oc­cupy protesters by resorting to brutal forms of punishment. This police violence at once made visible the modes of au­thoritarianism and culture of cruelty that permeate American society—as was seen even at universities and colleges across the United States, institutions charged with contributing to the intellectual, social, and moral growth of society’s youth.

As I complete the writing of this introduction, the Occupy struggle for social and economic justice continues on American university campuses—where the influence of austerity mea­sures is increasingly being felt, although the working conditions for faculty and the quality of education for students began to deteriorate under the neoliberal ascendancy decades ago. The issues impacting higher education are undoubtedly symptom­atic of the accelerated pace with which the withering away of the public realm is happening. The book finishes, however, by suggesting that the Occupy movement is far from over— despite the shrinking of physical space in which it can protest. As it expands and spreads across the globe, the movement is producing a new public realm of ideas and making important connections between the deteriorating state of education, an­tidemocratic forces, and the savage inequalities produced by a market society. The response of young people as the new generation of public intellectuals offers us both critique and hope. It is a call to work collectively to foster new modes of thought and action—one that should be actively supported by higher education and other remaining public spheres in the United States, if American democracy is to have a future at all.

Neuroscientists Pinpoint Location of Fear Memory in Amygdala (Science Daily)

Jan. 27, 2013 — A rustle of undergrowth in the outback: it’s a sound that might make an animal or person stop sharply and be still, in the anticipation of a predator. That “freezing” is part of the fear response, a reaction to a stimulus in the environment and part of the brain’s determination of whether to be afraid of it.

A neuroscience group at Cold Spring Harbor Laboratory (CSHL) led by Assistant Professor Bo Li Ph.D., together with collaborator Professor Z. Josh Huang Ph.D., have just released the results of a new study that examines the how fear responses are learned, controlled, and memorized. They show that a particular class of neurons in a subdivision of the amygdala plays an active role in these processes.

Locating fear memory in the amygdala

Previous research had indicated that structures inside the amygdalae, a pair of almond-shaped formations that sit deep within the brain and are known to be involved in emotion and reward-based behavior, may be part of the circuit that controls fear learning and memory. In particular, a region called the central amygdala, or CeA, was thought to be a passive relay for the signals relayed within this circuit.

Li’s lab became interested when they observed that neurons in a region of the central amygdala called the lateral subdivision, or CeL, “lit up” in a particular strain of mice while studying this circuit.

“Neuroscientists believed that changes in the strength of the connections onto neurons in the central amygdala must occur for fear memory to be encoded,” Li says, “but nobody had been able to actually show this.”

This led the team to further probe into the role of these neurons in fear responses and furthermore to ask the question: If the central amygdala stores fear memory, how is that memory trace read out and translated into fear responses?

To examine the behavior of mice undergoing a fear test the team first trained them to respond in a Pavlovian manner to an auditory cue. The mice began to “freeze,” a very common fear response, whenever they heard one of the sounds they had been trained to fear.

To study the particular neurons involved, and to understand them in relation to the fear-inducing auditory cue, the CSHL team used a variety of methods. One of these involved delivering a gene that encodes for a light-sensitive protein into the particular neurons Li’s group wanted to look at.

By implanting a very thin fiber-optic cable directly into the area containing the photosensitive neurons, the team was able to shine colored laser light with pinpoint accuracy onto the cells, and in this manner activate them. This is a technique known as optogenetics. Any changes in the behavior of the mice in response to the laser were then monitored.

A subset of neurons in the central amygdala controls fear expression

The ability to probe genetically defined groups of neurons was vital because there are two sets of neurons important in fear-learning and memory processes. The difference between them, the team learned, was in their release of message-carrying neurotransmitters into the spaces called synapses between neurons. In one subset of neurons, neurotransmitter release was enhanced; in another it was diminished. If measurements had been taken across the total cell population in the central amygdala, neurotransmitter levels from these two distinct sets of neurons would have been averaged out, and thus would not have been detected.

Li’s group found that fear conditioning induced experience-dependent changes in the release of neurotransmitters in excitatory synapses that connect with inhibitory neurons — neurons that suppress the activity of other neurons — in the central amygdala. These changes in the strength of neuronal connections are known as synaptic plasticity.

Particularly important in this process, the team discovered, were somatostatin-positive (SOM+) neurons. Somatostatin is a hormone that affects neurotransmitter release. Li and colleagues found that fear-memory formation was impaired when they prevent the activation of SOM+ neurons.

SOM+ neurons are necessary for recall of fear memories, the team also found. Indeed, the activity of these neurons alone proved sufficient to drive fear responses. Thus, instead of being a passive relay for the signals driving fear learning and responses in mice, the team’s work demonstrates that the central amygdala is an active component, and is driven by input from the lateral amygdala, to which it is connected.

“We find that the fear memory in the central amygdala can modify the circuit in a way that translates into action — or what we call the fear response,” explains Li.

In the future Li’s group will try to obtain a better understanding of how these processes may be altered in post-traumatic stress disorder (PTSD) and other disorders involving abnormal fear learning. One important goal is to develop pharmacological interventions for such disorders.

Li says more research is needed, but is hopeful that with the discovery of specific cellular markers and techniques such as optogenetics, a breakthrough can be made.

Primates, Too, Can Move in Unison (Science Daily)

Jan. 28, 2013 — Japanese researchers show for the first time that primates modify their body movements to be in tune with others, just like humans do. Humans unconsciously modify their movements to be in synchrony with their peers. For example, we adapt our pace to walk in step or clap in unison at the end of a concert. This phenomenon is thought to reflect bonding and facilitate human interaction. Researchers from the RIKEN Brain Science Institute report that pairs of macaque monkeys also spontaneously coordinate their movements to reach synchrony.

This research opens the door to much-needed neurophysiological studies of spontaneous synchronization in monkeys, which could shed light into human behavioral dysfunctions such as those observed in patients with autism spectrum disorders, echopraxia and echolalia — where patients uncontrollably imitate others.

In the research, recently published in the journal Scientific Reports, the team led by Naotaka Fujii developed an experimental set-up to test whether pairs of Japanese macaque monkeys synchronize a simple push-button movement.

Before the experiment, the monkeys were trained to push a button with one hand. In a first experiment the monkeys were paired and placed facing each other and the timing of their push-button movements was recorded. The same experiment was repeated but this time each monkey was shown videos of another monkey pushing a button at varying speeds. And in a last experiment the macaques were not allowed to either see or hear their video-partner.

The results show that the monkeys modified their movements — increased or decreased the speed of their push-button movement — to be in synchrony with their partner, both when the partner was real and on video. The speed of the button pressing movement changed to be in harmonic or sub-harmonic synchrony with the partners’ speed. However, different pairs of monkeys synchronized differently and reached different speeds, and the monkeys synchronized their movements the most when they could both see and hear their partner.

The researchers note that this behavior cannot have been learnt by the monkeys during the experiment, as previous research has shown that it is extremely difficult for monkeys to learn intentional synchronization.

They add: “The reasons why the monkeys showed behavioral synchronization are not clear. It may be a vital aspect of other socially adaptive behavior, important for survival in the wild.”

The study was partly supported by Grant-in-Aid for Scientific Research on Innovative Areas ‘Neural creativity for communication’ (22120522 and 24120720) of MEXT, Japan.

New Research Shows Complexity of Global Warming (Science Daily)

Jan. 30, 2013 — Global warming from greenhouse gases affects rainfall patterns in the world differently than that from solar heating, according to a study by an international team of scientists in the January 31 issue of Nature. Using computer model simulations, the scientists, led by Jian Liu (Chinese Academy of Sciences) and Bin Wang (International Pacific Research Center, University of Hawaii at Manoa), showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period, even though temperatures are higher today than they were then.

The team examined global precipitation changes over the last millennium and future projection to the end of 21st century, comparing natural changes from solar heating and volcanism with changes from human-made greenhouse gas emissions. Using an atmosphere-ocean coupled climate model that simulates realistically both past and present-day climate conditions, the scientists found that for every degree rise in global temperature, the global rainfall rate since the Industrial Revolution has increased less by about 40% than during past warming phases of Earth.

Why does warming from solar heating and from greenhouse gases have such different effects on global precipitation?

“Our climate model simulations show that this difference results from different sea surface temperature patterns. When warming is due to increased greenhouse gases, the gradient of sea surface temperature (SST) across the tropical Pacific weakens, but when it is due to increased solar radiation, the gradient increases. For the same average global surface temperature increase, the weaker SST gradient produces less rainfall, especially over tropical land,” says co-author Bin Wang, professor of meteorology.

But why does warming from greenhouse gases and from solar heating affect the tropical Pacific SST gradient differently?

“Adding long-wave absorbers, that is heat-trapping greenhouse gases, to the atmosphere decreases the usual temperature difference between the surface and the top of the atmosphere, making the atmosphere more stable,” explains lead-author Jian Liu. “The increased atmospheric stability weakens the trade winds, resulting in stronger warming in the eastern than the western Pacific, thus reducing the usual SST gradient — a situation similar to El Niño.”

Solar radiation, on the other hand, heats Earth’s surface, increasing the usual temperature difference between the surface and the top of the atmosphere without weakening the trade winds. The result is that heating warms the western Pacific, while the eastern Pacific remains cool from the usual ocean upwelling.

“While during past global warming from solar heating the steeper tropical east-west SST pattern has won out, we suggest that with future warming from greenhouse gases, the weaker gradient and smaller increase in yearly rainfall rate will win out,” concludes Wang.

Understanding the Historical Probability of Drought (Science Daily)

Jan. 30, 2013 — Droughts can severely limit crop growth, causing yearly losses of around $8 billion in the United States. But it may be possible to minimize those losses if farmers can synchronize the growth of crops with periods of time when drought is less likely to occur. Researchers from Oklahoma State University are working to create a reliable “calendar” of seasonal drought patterns that could help farmers optimize crop production by avoiding days prone to drought.

Historical probabilities of drought, which can point to days on which crop water stress is likely, are often calculated using atmospheric data such as rainfall and temperatures. However, those measurements do not consider the soil properties of individual fields or sites.

“Atmospheric variables do not take into account soil moisture,” explains Tyson Ochsner, lead author of the study. “And soil moisture can provide an important buffer against short-term precipitation deficits.”

In an attempt to more accurately assess drought probabilities, Ochsner and co-authors, Guilherme Torres and Romulo Lollato, used 15 years of soil moisture measurements from eight locations across Oklahoma to calculate soil water deficits and determine the days on which dry conditions would be likely. Results of the study, which began as a student-led class research project, were published online Jan. 29 inAgronomy Journal. The researchers found that soil water deficits more successfully identified periods during which plants were likely to be water stressed than did traditional atmospheric measurements when used as proposed by previous research.

Soil water deficit is defined in the study as the difference between the capacity of the soil to hold water and the actual water content calculated from long-term soil moisture measurements. Researchers then compared that soil water deficit to a threshold at which plants would experience water stress and, therefore, drought conditions. The threshold was determined for each study site since available water, a factor used to calculate threshold, is affected by specific soil characteristics.

“The soil water contents differ across sites and depths depending on the sand, silt, and clay contents,” says Ochsner. “Readily available water is a site- and depth-specific parameter.”

Upon calculating soil water deficits and stress thresholds for the study sites, the research team compared their assessment of drought probability to assessments made using atmospheric data. They found that a previously developed method using atmospheric data often underestimated drought conditions, while soil water deficits measurements more accurately and consistently assessed drought probabilities. Therefore, the researchers suggest that soil water data be used whenever it is available to create a picture of the days on which drought conditions are likely.

If soil measurements are not available, however, the researchers recommend that the calculations used for atmospheric assessments be reconfigured to be more accurate. The authors made two such changes in their study. First, they decreased the threshold at which plants were deemed stressed, thus allowing a smaller deficit to be considered a drought condition. They also increased the number of days over which atmospheric deficits were summed. Those two changes provided estimates that better agreed with soil water deficit probabilities.

Further research is needed, says Ochsner, to optimize atmospheric calculations and provide accurate estimations for those without soil water data. “We are in a time of rapid increase in the availability of soil moisture data, but many users will still have to rely on the atmospheric water deficit method for locations where soil moisture data are insufficient.”

Regardless of the method used, Ochsner and his team hope that their research will help farmers better plan the cultivation of their crops and avoid costly losses to drought conditions.

U.S. Water Supply Not as Threatened as Believed, Study Finds (Science Daily)

Jan. 30, 2013 — Although reports of drought conditions, water wars and restrictions have often painted a bleak picture of the nation’s water availability, a new University of Florida survey finds that conditions aren’t quite so bad as believed.

Jim Jawitz, a UF soil and water science professor, and Julie Padowski, who earned her doctoral degree from UF and is now a postdoctoral researcher at Stanford University, knew that previous assessments of urban water supplies typically used what is known as a “runoff-based approach,” which takes into account factors such as river flows and rainfall amounts.

Jawitz and Padowski knew that those assessments did not consider the infrastructure used to maintain urban water supplies, such as water stored in aquifers, lakes, reservoirs or water that’s pumped in to an area and stored. So for 225 U.S. metropolitan areas with populations of more than 100,000, that’s what they did, and their findings have been published online by the journal Water Resources Research.

When assessing cities using the runoff-based approach, the UF study found that 47 percent of the total U.S. population is vulnerable to water scarcity issues, however, when infrastructure was accounted for, the number dropped to just 17 percent of the population. Residents in the top 225 metropolitan areas make up the bulk of the U.S. population.

Jawitz, a faculty member with UF’s Institute of Food and Agricultural Sciences, said they expected to find fewer areas vulnerable to water shortages than past studies had because of the different methodology, but some of their findings surprised them.

“We have people who live in the desert and they have water and it’s because of their infrastructure. If you live in a city that has a large of reservoir of water stored and there’s a drought, it doesn’t have the same effect on you as if you live in a city where there’s a drought and you don’t have a large reservoir,” he said.

They didn’t expect Atlanta — where legal battles over water rights with neighboring states initially prompted the researchers to tackle the survey — to fall near the middle among the 225 cities they studied for water access and vulnerability.

Another unusual finding: Miami, with its lush, tropical landscape, landing in the top 10 most vulnerable cities. Jawitz, a South Florida native, said although the Miami area generally enjoys an abundance of rain, it’s not stored anywhere. That means during periods of drought, the area becomes vulnerable.

A website that ranks the 225 largest U.S. urban areas based on water availability and vulnerability can be found at soils.ifas.ufl.edu/hydrology/cities. The list is a combination of results of where each city falls on a 0-to-100 water-accessibility scale as well as a water-vulnerability rating of low, medium or high.

The researchers also had a modern twist to their study. Padowski created a media-text analysis to search online news archives for reports for each city, looking for stories about water restrictions or drought conditions.

They found that the media reports backed up their method of analysis but did not correlate significantly with estimates made using the runoff-based approach.

Padowski said despite the good news about water, she fully expects water conservation should and will be a front-and-center topic for many years to come.

“As population growth increases, we don’t have more resources to tap — we can’t just find another lake or another river to dam,” she said. “It’s going to come down to sharing, conservation and efficiency.”

Rob McDonald, senior scientist for sustainable land use with The Nature Conservancy, said the study adds to what scientists know about urban water use in the U.S. and raises intriguing questions about whether large cities’ infrastructure will be ready for conditions brought on by climate change.

“To me, it shows that infrastructure matters,” he said. “Do cities go out even further for water? If a city is dependent on snow melts from the mountains for its water, what happens if it gets warm enough that there isn’t a snowpack?”

The study was funded by the Florida Agricultural Experiment Station and the Adaptive Management of Water, Wetlands, and Watersheds IGERT program.

Revolução nas universidades (OESP)

JC e-mail 4656, de 30 de Janeiro de 2013.

Artigo de Thomas Friedman* no The New York Times, publicado no O Estado de São Paulo

Avanço do ensino superior online nas melhores escolas tornará o conceito de diploma algo arcaico; e isso é bom
Deus sabe que há muitas más notícias no mundo atual que nos derrubam, mas está ocorrendo alguma coisa formidável que me deixa esperançoso com relação ao futuro. Trata-se da revolução, incipiente, no ensino superior online.

Nada tem mais potencial para tirar as pessoas da pobreza – oferecendo a elas um ensino acessível que vai ajudá-las a conseguir trabalho ou ter melhores condições no seu emprego.
Nada tem mais potencial para libertar um bilhão de cérebros para solucionar os grandes problemas do mundo.

E nada tem mais potencial para recriar o ensino superior do que as MOOC (Massive Open Online Course), plataformas desenvolvidas por especialistas de Stanford, por colegas do MIT (Massachusetts Institute of Technology) e por empresas como Goursera e Udacity.

Em maio, escrevi um artigo sobre a Goursera – fundada por dois cientistas da computação de Stanford, Daphne Koller e Andrew Ng. Há duas semanas, retornei a Paio Alto para saber do seu progresso. Quando visitei a Goursera, em 2012, cerca de 300 mil pessoas participavam de 38 cursos proferidos por professores de Stanford e de outras universidades de elite.

Hoje, são 2,4 milhões de alunos e 214 cursos de 33 universidades, incluindo 8 internacionais. AnantAgarwal, ex-diretor do laboratório de inteligência artificial do MIT, hoje é presidente da edX, uma plataforma sem fins lucrativos criada em conjunto pelo MIT e pela Univer-sidade Harvard. Anant disse que, desde maio, cerca de 155 mil alunos do mundo todo participam do primeiro curso da edX: um curso introdutório sobre circuitos do MIT.

“E um número superior ao total dos alunos do MIT em sua história de 150 anos”, afirmou.
Claro que somente uma pequena porcentagem desses alunos completa o curso, mas estou convencido de que, dentro de cinco anos, essas plataformas alcançarão um público mais amplo. Imagine como isso poderá mudar a ajuda externa dos EUA.

Gastando relativamente pouco, o país poderia arrendar um espaço num vilarejo egípcio, instalar duas dezenas de computadores e dispositivos de acesso à internet de alta velocidade via satélite, contratar um professor local como coordenador e convidar todos os egípcios que desejarem ter aulas online com os melhores professores do mundo e legendas em árabe.

É preciso ouvir as histórias narradas pelos pioneiros dessa iniciativa para compreender seu potencial revolucionário. Uma das favoritas de Daphne Koller é sobre Daniel, um jovem de 17 anos com autismo que se comunica por meio do computador. Ele fez um curso online de poesia moderna oferecido pela Universidade da Pensilvânia.

Segundo Daniel e seus pais, a combinação de um currículo acadêmico rigoroso, que exige que ele se concentre na sua tarefa, e do sistema de aprendizado online, que não força sua capacidade de se relacionar, permite que ele administre melhor o autismo.

Daphne mostrou uma carta de Daniel em que ele escreveu: “Por favor, relateà Goursera e à Universidade da Pensilvânia a minhahistória. Souumjovem saindo do autismo. Ainda não consigo sentar-me numa sala de aula, de modo que esse foi meu primeiro curso de verdade.

Agora, sei que posso me beneficiar de um trabalho que exige muito de mim e ter o prazer de me sintonizar com o mundo.” Um membro da equipe do Goursera, que fez um curso sobre sustentabilida-de, me disse que foi muito mais interessante do que um estudo similar que ele fez na faculdade. Do curso online participaram estudantes do mundo todo e, assim, “as discussões que surgiram foram muito mais valiosas e interessantes do que os debates com pessoas iguais de uma típica faculdade americana. Mitch Duneier, professor de sociologia de Princeton, escreveu um ensaio sobre sua experiência ao dar aula num curso da Coursera.

“Há alguns meses, quando o campus de Princeton ficou quase em silêncio depois das cerimônias de graduação, 40 mil estudantes de 113 países chegaram aqui via internet para um curso grátis de introdução à sociologia. Minha aula de abertura, sobre o clássico de C. Wright Mills, de 1959, The Sociological Imagination, foi concentrada na leitura minuciosa do texto de um capítulo-chave. Pedi aos alunos para seguirem a análise em suas cópias, como faço em sala de aula. Quando dou essa aula em Princeton, normalmente, são feitas algumas perguntas perspicazes. Nesse caso, algumas horas depois de postar a versão online, os fóruns pegaram fogo, com centenas de comentários e perguntas. Alguns dias depois, eram milhares. Num espaço de três semanas, recebi mais feed-back sobre minhas ideias 11a área de sociologia do que em toda a minha carreira de professor, o que influenciou consideravelmente cada uma das minhas aulas e seminários seguintes.”

Anant Agarwal, da edX, fala sobre um estudante no Cairo que teve dificuldades e postou uma mensagem dizendo que pretendia abandonar o curso online. Em resposta, outros alunos no Cairo, da mesma classe, o convidaram para um encontro numa casa de chá, onde se ofereceram para ajudá-lo. Um estudante da Mongólia, de 15 anos, que estava na mesma classe, participando de um curso semipre-sencial, hoje está se candidatando a uma vaga no MIT e na Universidade da Califórnia, em Berkeley.

À medida que pensamos no futuro do ensino superior, segundo o presidente do MIT, Rafael Reif, algo que hoje chamamos “diploma” será um conceito relacionado com “tijolos e argamassa” – e as tradicionais experiências 110 campus, que influenciarão cada vez mais a tecnologia e a internet para melhorar o trabalho em sala de aula e no laboratório.

Ao lado disso, contudo, muitas universidades oferecerão cursos online para estudantes de qualquer parte do mundo, em que eles conseguirão “credenciais” – ou seja, certificados atestando que realizaram o trabalho e passaram, em todos os exames.

O processo de criação de credenciais fidedignas certificando que o aluno domina adequadamente o assunto – e no qual um empregador pode confiar ainda está sendo aperfeiçoado por todos os MOOCs. No entanto, uma vez resolvida a questão, esse fenômeno realmente se propagará muito.

Posso ver o dia em que você criará o seu diploma universitário participando dos melhores cursos online com os mais capacitados professores do mundo todo – de computação de Stanford, de empreendedorismo da Wharton, de ética da Brandeis, de literatura da Universidade de Edimburgo – pagando apenas uma taxa pelo certificado de conclusão do curso. Isso mudará o ensino, o aprendizado e o caminho para o emprego.

“Um novo mundo está se revelando”, disse Reif. “E todos terão de se adaptar”.

Digestão bloqueada, praga controlada (Revista Fapesp)

[Curioso que tanto receio exista com relação à geoengenharia, e tão pouco direcionado a esse tipo de zooengenharia.]
Pesquisa da função intestinal de insetos aumenta o conhecimento da fisiologia desses animais e pode ajudar a criar métodos inovadores de combater doenças e controlar pragas da lavoura (estrutura 3D da catepsina L2)

30/01/2013

Por Fábio Reynol

Agência FAPESP – Diversas enfermidades humanas, como dengue, doença de chagas e leishmaniose, e pragas que destroem lavouras de algodão, cana-de-açúcar e bananeira são problemas que têm como ponto comum o fato de serem provocadas por insetos.

Uma extensa pesquisa feita no Instituto de Química (IQ) da Universidade de São Paulo (USP) ampliou o conhecimento sobre diferentes insetos por meio de uma abordagem peculiar: a investigação da função intestinal. Com isso, abriu espaço para métodos inovadores de controle.

O trabalho compôs o projeto “A digestão dos insetos: uma abordagem molecular, celular, fisiológica e evolutiva”, conduzido de 2008 a 2012 e apoiado pela FAPESP por meio da modalidade Auxílio à Pesquisa – Projeto Temático.

O projeto, coordenado por Walter Ribeiro Terra, professor titular do IQ-USP – com a professora Clelia Ferreira como investigadora principal e vice-coordenadora –, é uma continuação de Temáticos sobre o mesmo tema desenvolvidos desde 1991. O novo projeto teve início em 2012 com conclusão prevista para 2017.

Entre as principais descobertas do projeto concluído este ano foi a de que mosquitos hematófagos da ordem Díptera têm em comum tripsinas especiais, fundamentais para a digestão de proteínas. “Essa informação torna esse tipo de tripsina um possível alvo de controle para todos os mosquitos desse grupo”, disse Terra.

Trata-se de um alvo bastante relevante, uma vez que a ordem Díptera engloba os gênerosAnophelesAedes e Culex, os quais agrupam insetos vetores de importantes doenças como malária, febre amarela, dengue e filariose.

Segundo Terra, inibir a tripsina poderia ser um método eficaz de controle dessas doenças, uma vez que bloquearia o processo de digestão dos insetos. Para isso, o trabalho também envolveu a busca por inibidores químicos das enzimas encontradas.

O método utilizado foi o da modelagem computacional a partir de imagens tridimensionais dessas moléculas. Em um modelo digital em 3D da enzima a ser inibida são testadas virtualmente moléculas inibidoras que se encaixam no maior número possível de reentrâncias, ou sítios funcionais.

“Em quanto mais sítios funcionais o reagente atracar, mais forte será a ligação e mais eficiente será o inibidor”, disse Terra à Agência FAPESP, explicando que a modelagem molecular 3D é amplamente usada na indústria farmacêutica.

A enzima bloqueada não consegue se recombinar e cumprir sua função no processo de digestão, o de quebrar outras moléculas. Sem conseguir absorver os nutrientes de que precisam, os mosquitos morrem.

O estudo da fisiologia do barbeiro Rhodnius prolixus, vetor da doença de chagas, sempre foi difícil e a observação de sua função intestinal um obstáculo para os pesquisadores.

A equipe de Terra contornou o problema encontrando um inseto similar, o Dysdercus peruvianus, percevejo que ataca o algodão. Transcriptomas (partes do genoma que codificam proteínas) desse inseto mostraram detalhes que podem ser válidos também para o barbeiro, podendo gerar alvos de controle naquele inseto.

O agronegócio da cana-de-açúcar também poderá se beneficiar do estudo. A catepsina L, enzima digestiva típica de muitos besouros, foi isolada no Sphenophorus levis, besouro cuja fase larval ataca o sistema radicular da cana. Essa enzima foi clonada, expressa e caracterizada com substratos sintéticos e inibidores. A mesma enzima encontrada no Tenebrio molitor, besouro conhecido como bicho-da-farinha, teve sua estrutura tridimensional resolvida.

“O maior desafio em identificar a estrutura tridimensional é a cristalização da proteína, porque se ela não cristaliza não conseguimos obter o modelo”, disse Terra, esclarecendo que várias proteínas não conseguem formar cristais, inviabilizando a sua visualização tridimensional.

Estrutura do desenvolvimento

Uma estrutura particular do sistema intestinal dos insetos recebeu atenção especial no Projeto Temático conduzido no IQ-USP: a membrana peritrófica.

Em formato de um minúsculo tubo, sabe-se que seu papel está ligado à eficiência digestiva, porém suas funções ainda não são totalmente conhecidas pela ciência. Algumas dessas funções hipotéticas foram testadas em insetos modelos e descobriu-se que ela possui participação preponderante no desenvolvimento dos insetos.

Insetos cujas membranas peritróficas foram inibidas tiveram o seu desenvolvimento prejudicado. Ao mesmo tempo, algumas plantas possuem reagentes naturais que atacam essa membrana, o que as protege de serem devoradas por insetos. “Essas informações tornam essa estrutura um importante alvo para processos inovadores de controle”, observou Terra.

O Projeto Temático também promoveu avanços consideráveis no conhecimento da evolução das espécies. Além de possível alvo de controle das moscas domésticas, a enzima catepsina D também está presente em humanos e em outros animais que possuem sistemas digestivos muito ácidos voltados a processar alimentos ricos em bactérias.

“O interessante dessa descoberta foi constatar que a mesma adaptação evolutiva ocorreu duas vezes e de maneira independente na mosca e na espécie humana”, disse Terra.

Outro avanço importante foi sobre a morfofisiologia dos insetos. Um estudo com o percevejoPodisus nigrispinus, predador de outros insetos, mostrou que a então chamada digestão extraoral daquele inseto é uma dispersão dos tecidos da presa por ação de uma substância salivar. A digestão propriamente dita ocorre no interior do intestino do inseto.

A descoberta, publicada no Journal of Insect Physiology, provocou uma menção especial de um parecerista da revista. “Ele escreveu que a partir desse trabalho deve-se repensar os conceitos de digestão fora do corpo”, disse Terra, salientando que a equipe recebeu com muito orgulho esse reconhecimento.

O projeto ainda identificou a lisozima como uma enzima crítica na digestão de moscas que atacam frutas, a trealase é crucial para lagartas pragas de lavouras e as beta-glucanases, ausentes nos mamíferos, estão relacionadas à digestão e ao sistema imunológico de insetos. Todas elas são potenciais alvos de controle dos insetos envolvidos.

Mais de 1,3 mil citações

Os resultados dos quatro anos de estudos estão registrados em 20 publicações e quatro capítulos de livros e os trabalhos de laboratório do projeto foram citados 1.357 vezes na literatura científica mundial nesse período.

No âmbito do Projeto Temático foram desenvolvidas três dissertações de mestrado, seis teses de doutorado e duas de pós-doutorado. O projeto contou com cinco Bolsas FAPESP de Iniciação Científica, uma de Doutorado e as duas de Pós-Doutorado.

O Temático ainda promoveu trabalhos em parcerias com diversas instituições nacionais como a Universidade Federal de Santa Catarina (UFSC), a Universidade Federal de Lavras (UFL), a Universidade Federal de São Carlos (UFSCar), o Instituto Nacional de Ciência e Tecnologia (INCT) de Entomologia Molecular do qual o IQ-USP faz parte e a Escola Superior de Agricultura Luiz de Queiroz (Esalq) também da USP.

O grupo ainda participa de um consórcio internacional para o sequenciamento do genoma do barbeiro Rhodnius prolixus cujos resultados ainda estão em análise e, de acordo com Terra, ainda devem gerar diversas aplicações práticas.

Cultural Evolution Changes Bird Song (Science Daily)

Jan. 29, 2013 — Thanks to cultural evolution, male Savannah sparrows are changing their tune, partly to attract “the ladies.”

According to a study of more than 30 years of Savannah sparrows recordings, the birds are singing distinctly different songs today than their ancestors did 30 years ago — changes passed along generation to generation, according to a new study by University of Guelph researchers.

Integrative biology professors Ryan Norris and Amy Newman, in collaboration with researchers at Bowdoin College and Williams College in the U.S., analyzed the songs of male Savannah sparrows (Passerculus sandwichiensis) recorded over three decades, and found that the songs had changed distinctly from 1980 to 2011.

“The change is the result of cultural transmission of different song elements through many generations,” said Norris.

Norris added that the change in tune resembles changes in word choice and language among humans.

“If you listen to how people used to talk in the 1890s and how we talk today, you would notice major differences, and this is the result of shifts in culture or the popularity of certain forms,” he said. “The change in sparrow songs over time has occurred much the same way”

The sparrows, which live on Kent Island, N.B., in the Bay of Fundy, can generally sing only one song type that consists of several parts. Male sparrows learn that song early in their first year and continue to sing the same tune for the rest of their lives.

“Young male sparrows learn their songs from the birds around them,” said Norris. “It may be their fathers, or it could be other older male birds that live nearby.”

Each male sparrow has his own unique sound, added Newman.

“While the island’s sparrows all sing a characteristic ‘savannah sparrow song,’ with the same verses and sound similar, there are distinct differences between each bird,” she said. “Essentially, it is like karaoke versions of popular songs. It is the rise and fall in popular cover versions that has changed over time.”

The research team found that, in general, each song has three primary elements. The first identifies the bird as a Savannah sparrow, the second identifies which individual is singing, and the third component is used by females to assess males.

Using sonograms recorded from singing males each breeding season, the researchers determined that, while the introductory notes had stayed generally consistent for the last 30 years, the sparrows had added a series of clicks to the middle of their songs. The birds had also changed the ending trill: once long and high-frequency, it is now shorter and low-frequency.

“We found that the ending trill of the song has become shorter, likely because female sparrows preferred this, because males with shorter trills had higher reproductive success,” Norris said.

Kent Island has been home to the Bowdoin Scientific Station since it was donated by J. Sterling Rockefeller in 1932, and the birds have been recorded since the 1980s. Individual birds are also monitored throughout their lifetime.

“We know the identity and history of every single sparrow in the study population” said Norris, who has led the project with Newman since 2009. “To have 30 years of recordings is very rare, and it was definitely surprising to see such drastic changes.”

Make climate change a priority (Washington Post)

Graphic: A new report prepared for the World Bank finds that the planet is on a path to warming 4 degrees by the end of the century, with devastating consequences. Click on the infographic to go to the World Bank for more information.

By Jim Yong Kim, Published: January 24

Jim Yong Kim is president of the World Bank.

The weather in Washington has been like a roller coaster this January. Yes, there has been a deep freeze this week, but it was the sudden warmth earlier in the month that was truly alarming. Flocks of birds — robins, wrens, cardinals and even blue jays – swarmed bushes with berries, eating as much as they could. Runners and bikers wore shorts and T-shirts. People worked in their gardens as if it were spring.

The signs of global warming are becoming more obvious and more frequent. A glut of extreme weather conditions is appearing globally. And the average temperature in the United States last year was the highest ever recorded.

As economic leaders gathered in Davos this week for the World Economic Forum, much of the conversation was about finances. But climate change should also be at the top of our agendas, because global warming imperils all of the development gains we have made.If there is no action soon, the future will become bleak. The World Bank Groupreleased a reportin November that concluded that the world could warm by 7.2 degrees Fahrenheit (4 degrees Celsius) by the end of this century if concerted action is not taken now.

A world that warm means seas would rise 1.5 to 3 feet, putting at risk hundreds of millions of city dwellers globally. It would mean that storms once dubbed “once in a century” would become common, perhaps occurring every year. And it would mean that much of the United States, from Los Angeles to Kansas to the nation’s capital, would feel like an unbearable oven in the summer.

My wife and I have two sons, ages 12 and 3. When they grow old, this could be the world they inherit. That thought alone makes me want to be part of a global movement that acts now.

Even as global climate negotiations continue, there is a need for urgent action outside the conventions. People everywhere must focus on where we will get the most impact to reduce emissions and build resilience in cities, communities and countries.

Strong leadership must come from the six big economies that account for two-thirds of the energy sector’s global carbon dioxide emissions. President Obama’s reference in his inaugural address this week to addressing climate and energy could help reignite this critical conversation domestically and abroad.

The world’s top priority must be to get finance flowing and get prices right on all aspects of energy costs to support low-carbon growth. Achieving a predictable price on carbon that accurately reflects real environmental costs is key to delivering emission reductions at scale. Correct energy pricing can also provide incentives for investments in energy efficiency and cleaner energy technologies.

A second immediate step is to end harmful fuel subsidies globally, which could lead to a 5 percent fall in emissions by 2020. Countries spend more than $500 billion annually in fossil-fuel subsidies and an additional $500 billion in other subsidies, often related to agriculture and water, that are, ultimately, environmentally harmful. That trillion dollars could be put to better use for the jobs of the future, social safety nets or vaccines.

A third focus is on cities. The largest 100 cities that contribute 67 percent of energy-related emissions are both the center of innovation for green growth and the most vulnerable to climate change. We have seen great leadership, for example, in New York and Rio de Janeiro on low-carbon growth and tackling practices that fuel climate change.

At the World Bank Group, through the $7 billion-plus Climate Investment Funds, we are managing forests, spreading solar energy and promoting green expansion for cities, all with a goal of stopping global warming. We also are in the midst of a major reexamination of our own practices and policies.

Just as the Bretton Woods institutions were created to prevent a third world war, the world needs a bold global approach to help avoid the climate catastrophe it faces today. The World Bank Group is ready to work with others to meet this challenge. With every investment we make and every action we take, we should have in mind the threat of an even warmer world and the opportunity of inclusive green growth.

After the hottest year on record in the United States, a year in which Hurricane Sandycaused billions of dollars in damagerecord droughts scorched farmland in the Midwest and our organization reported that the planet could become more than 7 degrees warmer, what are we waiting for? We need to get serious fast. The planet, our home, can’t wait.

Scientists discover how epigenetic information could be inherited (University of Cambridge)

Public release date: 24-Jan-2013

Research reveals the mechanism of epigenetic reprogramming

New research reveals a potential way for how parents’ experiences could be passed to their offspring’s genes. The research was published today, 25 January, in the journal Science.

Epigenetics is a system that turns our genes on and off. The process works by chemical tags, known as epigenetic marks, attaching to DNA and telling a cell to either use or ignore a particular gene.

The most common epigenetic mark is a methyl group. When these groups fasten to DNA through a process called methylation they block the attachment of proteins which normally turn the genes on. As a result, the gene is turned off.

Scientists have witnessed epigenetic inheritance, the observation that offspring may inherit altered traits due to their parents’ past experiences. For example, historical incidences of famine have resulted in health effects on the children and grandchildren of individuals who had restricted diets, possibly because of inheritance of altered epigenetic marks caused by a restricted diet.

However, it is thought that between each generation the epigenetic marks are erased in cells called primordial gene cells (PGC), the precursors to sperm and eggs. This ‘reprogramming’ allows all genes to be read afresh for each new person – leaving scientists to question how epigenetic inheritance could occur.

The new Cambridge study initially discovered how the DNA methylation marks are erased in PGCs, a question that has been under intense investigation over the past 10 years. The methylation marks are converted to hydroxymethylation which is then progressively diluted out as the cells divide. This process turns out to be remarkably efficient and seems to reset the genes for each new generation. Understanding the mechanism of epigenetic resetting could be exploited to deal with adult diseases linked with an accumulation of aberrant epigenetic marks, such as cancers, or in ‘rejuvenating’ aged cells.

However, the researchers, who were funded by the Wellcome Trust, also found that some rare methylation can ‘escape’ the reprogramming process and can thus be passed on to offspring – revealing how epigenetic inheritance could occur. This is important because aberrant methylation could accumulate at genes during a lifetime in response to environmental factors, such as chemical exposure or nutrition, and can cause abnormal use of genes, leading to disease. If these marks are then inherited by offspring, their genes could also be affected.

Dr Jamie Hackett from the University of Cambridge, who led the research, said: “Our research demonstrates how genes could retain some memory of their past experiences, revealing that one of the big barriers to the theory of epigenetic inheritance – that epigenetic information is erased between generations – should be reassessed.”

“It seems that while the precursors to sperm and eggs are very effective in erasing most methylation marks, they are fallible and at a low frequency may allow some epigenetic information to be transmitted to subsequent generations. The inheritance of differential epigenetic information could potentially contribute to altered traits or disease susceptibility in offspring and future descendants.”

“However, it is not yet clear what consequences, if any, epigenetic inheritance might have in humans. Further studies should give us a clearer understanding of the extent to which heritable traits can be derived from epigenetic inheritance, and not just from genes. That could have profound consequences for future generations.”

Professor Azim Surani from the University of Cambridge, principal investigator of the research, said: “The new study has the potential to be exploited in two distinct ways. First, the work could provide information on how to erase aberrant epigenetic marks that may underlie some diseases in adults. Second, the study provides opportunities to address whether germ cells can acquire new epigenetic marks through environmental or dietary influences on parents that may evade erasure and be transmitted to subsequent generations, with potentially undesirable consequences.”

Sociologists Find Similarities in Meanings Behind Protestant Work Ethic, Religious Tattoos (Science Daily)

Jan. 23, 2013 — When it comes to religious tattoos, two Texas Tech University sociologists say the reasoning and spirit behind them is strikingly similar to a 100-year-old theory about how the Protestant work ethic powered the Industrial Revolution.

Professors Jerry Koch and Alden Roberts recently published their findings in the peer-reviewed The Social Science Journal.

Both sociologists said the sentiment behind the tattoos is reminiscent of Max Weber’s famous 1905 sociological work “The Protestant Ethic and the Spirit of Capitalism.” Koch and Roberts’ research is part of a larger study called Religion and Deviance at Four American Universities, which expands their research from the previous five years to give more national context.

“This particular article came out of some data we gathered and started as an afterthought to a pilot study,” Koch said. “At the end of the questionnaire, we appended an essay question and gave respondents a chance to tell us, if they had one, the story of their religious tattoo. As we started reading through the essays they wrote for us, we started to hear what we knew Max Weber would have appreciated. That, in a sense, these respondents were telling us ‘I want everyone to know that I believe I’m one of God’s people; and here is the evidence of that.'”

Go back nearly 100 years ago, and Weber described in this founding text of economic sociology how Calvinist views on their purpose on the planet helped to drive the Industrial Revolution, Koch said. A person’s profession, no matter how grand or lowly, was seen as an addition to the greater common good, and thereby blessed by God as a sacred calling. Work, for these Protestants, became a visible expression of their faith, and consequently helped to drive the machinery of the unplanned Industrial Revolution of the 19th century.

“Weber argued that the diligence and integrity that we often associate with Protestant work ethic was in one sense a way for individuals to demonstrate to themselves and others that they must be one of God’s elect, otherwise why would they be doing so well,” Koch said. “We are making the parallel saying that the rationale behind and the energy it takes to get a religious tattoo is perhaps to show the same thing.”

In Koch and Roberts’ study, the two gathered tattoo survey data from about 70 undergraduates at four American universities. Two were large, state-supported public institutions, and the other two were highly selective, private religious universities.

Koch and Roberts both noted this same Weberian spirit of public expression as respondents to their last-minute questions repeatedly indicated that their religious tattoos were, for them, evidence of the permanence of their faith, outward signs of religious commitment, or memorials to those they’ve loved and lost and presumably who they hoped went to heaven when they died.

About 65 percent of the respondents with religious tattoos came from secular state schools, the two found. However, 44 percent of the Southern Baptist students that reported having tattoos indicated that at least one was religious.

“The reasons for the religious tattoos were some people wanted a permanent reminder, or permanent advertisement to others,” Roberts said. “There were some that were troubled by the idea the body being a temple, others were not as troubled by that. Those who got religious tattoos were more likely to overtly express religiosity.”

The permanence of a tattoo drew many to get one as a permanent insignia of their faith. Several indicated they got it in memory of someone that they loved, Koch said, while others got it as a way of telling themselves and others that their life had changed.

“One respondent explicitly said ‘I got this tattoo after I lost my virginity as a recommitment to purity,'” Koch said. “It was surprising and a happy accident that the information mirrored where Weber was coming from. I hadn’t anticipated that at the end of the day we would have what I think is a useful teaching tool for showing students what Weber was about using this new imagery.”

Scientists Underestimated Potential for Tohoku Earthquake: Now What? (Science Daily)

Jan. 23, 2013 — The massive Tohoku, Japan, earthquake in 2011 and Sumatra-Andaman superquake in 2004 stunned scientists because neither region was thought to be capable of producing a megathrust earthquake with a magnitude exceeding 8.4.

Now earthquake scientists are going back to the proverbial drawing board and admitting that existing predictive models looking at maximum earthquake size are no longer valid.

In a new analysis published in the journal Seismological Research Letters, a team of scientists led by Oregon State University’s Chris Goldfinger describes how past global estimates of earthquake potential were constrained by short historical records and even shorter instrumental records. To gain a better appreciation for earthquake potential, he says, scientists need to investigate longer paleoseismic records.

“Once you start examining the paleoseismic and geodetic records, it becomes apparent that there had been the kind of long-term plate deformation required by a giant earthquake such as the one that struck Japan in 2011,” Goldfinger said. “Paleoseismic work has confirmed several likely predecessors to Tohoku, at about 1,000-year intervals.”

The researchers also identified long-term “supercycles” of energy within plate boundary faults, which appear to store this energy like a battery for many thousands of years before yielding a giant earthquake and releasing the pressure. At the same time, smaller earthquakes occur that do not to any great extent dissipate the energy stored within the plates.

The newly published analysis acknowledges that scientists historically may have underestimated the number of regions capable of producing major earthquakes on a scale of Tohoku.

“Since the 1970s, scientists have divided the world into plate boundaries that can generate 9.0 earthquakes versus those that cannot,” said Goldfinger, a professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences. “Those models were already being called into question when Sumatra drove one stake through their heart, and Tohoku drove the second one.

“Now we have no models that work,” he added, “and we may not have for decades. We have to assume, however, that the potential for 9.0 subduction zone earthquakes is much more widespread than originally thought.”

Both Tohoku and Sumatra were written off in the textbooks as not having the potential for a major earthquake, Goldfinger pointed out.

“Their plate age was too old, and they didn’t have a really large earthquake in their recent history,” Goldfinger said. “In fact, if you look at a northern Japan seismic risk map from several years ago, it looks quite benign — but this was an artifact of recent statistics.”

Paleoseismic evidence of subduction zone earthquakes is not yet plentiful in most cases, so little is known about the long-term earthquake potential of most major faults. Scientists can determine whether a fault has ruptured in the past — when and to what extent — but they cannot easily estimate how big a specific earthquake might have been. Most, Goldfinger says, fall into ranges — say, 8.4 to 8.7.

Nevertheless, that type of evidence can be more telling than historical records because it may take many thousands of years to capture the full range of earthquake behavior.

In their analysis, the researchers point to several subduction zone areas that previously had been discounted as potential 9.0 earthquake producers — but may be due for reconsideration. These include central Chile, Peru, New Zealand, the Kuriles fault between Japan and Russia, the western Aleutian Islands, the Philippines, Java, the Antilles Islands and Makran, Pakistan/Iran.

Onshore faults such as the Himalayan Front may also be hiding outsized earthquakes, the researchers add. Their work was supported by the National Science Foundation.

Goldfinger, who directs the Active Tectonics and Seafloor Mapping Laboratory at Oregon State, is a leading expert on the Cascadia Subduction Zone off the Pacific Northwest coast of North America. His comparative studies have taken him to the Indian Ocean, Japan and Chile, and in 2007, he led the first American research ship into Sumatra waters in nearly 30 years to study similarities between the Indian Ocean subduction zone and Cascadia.

Paleoseismic evidence abounds in the Cascadia Subduction Zone, Goldfinger pointed out. When a major offshore earthquake occurs, the disturbance causes mud and sand to begin streaming down the continental margins and into the undersea canyons. Coarse sediments called turbidites run out onto the abyssal plain; these sediments stand out distinctly from the fine particulate matter that accumulates on a regular basis between major tectonic events.

By dating the fine particles through carbon-14 analysis and other methods, Goldfinger and colleagues can estimate with a great deal of accuracy when major earthquakes have occurred. Over the past 10,000 years, there have been 19 earthquakes that extended along most of the Cascadia Subduction Zone margin, stretching from southern Vancouver Island to the Oregon-California border.

“These would typically be of a magnitude from about 8.7 to 9.2 — really huge earthquakes,” Goldfinger said. “We’ve also determined that there have been 22 additional earthquakes that involved just the southern end of the fault. We are assuming that these are slightly smaller — more like 8.0 — but not necessarily. They were still very large earthquakes that if they happened today could have a devastating impact.”

Other researchers on the analysis include Yasutaka Ikeda of University of Tokyo, Robert S. Yeats of Oregon State University, and Junjie Ren, of the Chinese Seismological Bureau.

Climate Change Beliefs of Independent Voters Shift With the Weather (Science Daily)

Jan. 24, 2013 — There’s a well-known saying in New England that if you don’t like the weather here, wait a minute. When it comes to independent voters, those weather changes can just as quickly shift beliefs about climate change.

New research from the University of New Hampshire finds that the climate change beliefs of independent voters are dramatically swayed by short-term weather conditions. The research was conducted by Lawrence Hamilton, professor of sociology and senior fellow at the Carsey Institute, and Mary Stampone, assistant professor of geography and the New Hampshire state climatologist.

“We find that over 10 surveys, Republicans and Democrats remain far apart and firm in their beliefs about climate change. Independents fall in between these extremes, but their beliefs appear weakly held — literally blowing in the wind. Interviewed on unseasonably warm days, independents tend to agree with the scientific consensus on human-caused climate change. On unseasonably cool days, they tend not to,” Hamilton and Stampone say.

Hamilton and Stampone used statewide data from about 5,000 random-sample telephone interviews conducted on 99 days over two and a half years (2010 to 2012) by the Granite State Poll. They combined the survey data with temperature and precipitation indicators derived from New Hampshire’s U.S. Historical Climatology Network (USHCN) station records. Survey respondents were asked whether they thought climate change is happening now, caused mainly by human activities. Alternatively, respondents could state that climate change is not happening, or that it is happening but mainly for natural reasons.

Unseasonably warm or cool temperatures on the interview day and previous day seemed to shift the odds of respondents believing that humans are changing the climate. However, when researchers broke these responses down by political affiliation (Democrat, Republican or independent), they found that temperature had a substantial effect on climate change views mainly among independent voters.

“Independent voters were less likely to believe that climate change was caused by humans on unseasonably cool days and more likely to believe that climate change was caused by humans on unseasonably warm days. The shift was dramatic. On the coolest days, belief in human-caused climate change dropped below 40 percent among independents. On the hottest days, it increased above 70 percent,” Hamilton says.

New Hampshire’s self-identified independents generally resemble their counterparts on a nationwide survey that asked the same questions, according to the researchers. Independents comprise 18 percent of the New Hampshire estimation sample, compared with 17 percent nationally. They are similar with respect to education, but slightly older, and more balanced with respect to gender.

In conducting their analysis, the researchers took into account other factors such as education, age, and sex. They also made adjustments for the seasons, and for random variation between surveys that might be caused by nontemperature events.

The Storm That Never Was: Why Meteorologists Are Often Wrong (Science Daily)

Jan. 24, 2013 — Have you ever woken up to a sunny forecast only to get soaked on your way to the office? On days like that it’s easy to blame the weatherman.

But BYU mechanical engineering professor Julie Crockett doesn’t get mad at meteorologists. She understands something that very few people know: it’s not the weatherman’s fault he’s wrong so often.

According to Crockett, forecasters make mistakes because the models they use for predicting weather can’t accurately track highly influential elements called internal waves.

Atmospheric internal waves are waves that propagate between layers of low-density and high-density air. Although hard to describe, almost everyone has seen or felt these waves. Cloud patterns made up of repeating lines are the result of internal waves, and airplane turbulence happens when internal waves run into each other and break.

“Internal waves are difficult to capture and quantify as they propagate, deposit energy and move energy around,” Crockett said. “When forecasters don’t account for them on a small scale, then the large scale picture becomes a little bit off, and sometimes being just a bit off is enough to be completely wrong about the weather.”

One such example may have happened in 2011, when Utah meteorologists predicted an enormous winter storm prior to Thanksgiving. Schools across the state cancelled classes and sent people home early to avoid the storm. Though it’s impossible to say for sure, internal waves may have been driving stronger circulations, breaking up the storm and causing it to never materialize.

“When internal waves deposit their energy it can force the wind faster or slow the wind down such that it can enhance large scale weather patterns or extreme kinds of events,” Crockett said. “We are trying to get a better feel for where that wave energy is going.”

Internal waves also exist in oceans between layers of low-density and high-density water. These waves, often visible from space, affect the general circulation of the ocean and phenomena like the Gulf Stream and Jet Stream.

Both oceanic and atmospheric internal waves carry a significant amount of energy that can alter climates.

Crockett’s latest wave research, which appears in a recent issue of the International Journal of Geophysics, details how the relationship between large-scale and small-scale internal waves influences the altitude where wave energy is ultimately deposited.

To track wave energy, Crockett and her students generate waves in a tank in her lab and study every aspect of their behavior. She and her colleagues are trying to pinpoint exactly how climate changes affect waves and how those waves then affect weather.

Based on this, Crockett can then develop a better linear wave model with both 3D and 2D modeling that will allow forecasters to improve their weather forecasting.

“Understanding how waves move energy around is very important to large scale climate events,” Crockett said. “Our research is very important to this problem, but it hasn’t solved it completely.”

PM dá ordem para abordar ‘negros e pardos’ (Diário de São Paulo)

23/01/2013 14:00

Instrução de comandante de batalhão se baseou na descrição de vítima de assalto em bairro luxuoso

Por THAÍS NUNES 

Desde o dia 21 de dezembro do ano passado, policiais militares do bairro Taquaral, um dos mais nobres de Campinas, cumprem a ordem de abordar “indivíduos em atitude suspeita, em especial os de cor parda e negra”. A orientação foi dada pelo oficial que chefia a companhia responsável pela região, mas o Comando da PM nega teor racista na determinação.

O documento assinado pelo capitão Ubiratan de Carvalho Góes Beneducci orienta a tropa a agir com rigor, caso se depare com jovens de 18 a 25 anos, que estejam em grupos de três a cinco pessoas e tenham a pele escura. Essas seriam as características de um suposto grupo que comete assaltos a residências no bairro.

A ordem do oficial foi motivada por uma carta de dois moradores. Um deles foi vítima de um roubo e descreveu os criminosos dessa maneira. Nenhum deles, entretanto, foi identificado pela Polícia Militar para que as abordagens fossem direcionadas nesse sentido.

Para o frei Galvão, da Educafro, a ordem de serviço dá a entender que, caso os policiais cruzem com um grupo de brancos, não há perigo. Na manhã de hoje, ele pretende enviar um pedido de explicações ao governador Geraldo Alckmin e ao secretário da Segurança Pública, Fernando Grella.

O DIÁRIO solicitou entrevista com o capitão Beneducci, sem sucesso. A reportagem também  pediu outro ofício semelhante, em que o alvo das abordagens fosse um grupo de jovens brancos, mas não obteve resposta até o fim desta edição.

Confira a íntegra da nota de esclarecimento enviada pelo Comando da Polícia Militar:

A Polícia Militar lamenta que um grupo historicamente discriminado pela sociedade, que são os negros, seja usado para fazer sensacionalismo.

O caso concreto trata de ordem escrita de uma autoridade policial militar, atendendo aos pedidos da comunidade local, no sentido de reforçar o policiamento com vistas a um grupo de criminosos, com características específicas, que por acaso era formado por negros e pardos. A ordem é clara quanto à referência a esse grupo: “focando abordagens a transeuntes e em veículos em atitude suspeita, especialmente indivíduos de cor parda e negra com idade aparentemente de 18 a 25 anos, os quais sempre estão em grupo de 3 a 5 indivíduos na prática de roubo a residência naquela localidade”.

A ordem descreve ainda os locais (quatro ruas) e horário em que os crimes ocorrem. Logo, não há o que se falar em discriminação ou em atitude racista, tendo o capitão responsável emitido a ordem com base em indicadores concretos e reais. Discriminação e racismo é o fato de explorar essa situação de maneira irresponsável e fora de contextualização.

Belo Monte é um absurdo e termelétricas são desnecessárias [((o))eco]

Daniele Bragança

22 de Janeiro de 2013

Para Célio Bermann, eletricidade produzida com excedente de bagaço de cana equivaleria a duas Belo Montes.

O setor de energia ganhou as primeiras páginas dos jornais no início de 2013 com o baixo nível dos reservatórios e a possibilidade de manter as termelétricas ligadas ao longo de todo o ano para compensar a falta de chuvas. Célio Bermann, professor do Instituto de Eletrotécnica e Energia da USP, é um crítico severo dessa solução. Um dos mais respeitados especialistas na área energética do país, trabalhou como assessor da então Ministra Dilma Rousseff no Ministério de Minas e Energia, entre 2003 e 2004. “Saí quando verifiquei que o Ministério de Minas e Energia estava fazendo o contrário do que eu pensava que seria possível”, diz ele. Severo crítico da hidrelétrica de Belo Monte, fez parte do painel de especialistasque concluíram que o projeto da usina não deveria ter seguimento.

Bermann conversou com ((o))eco sobre os caminhos do setor energético e possíveis soluções para evitar o uso intensivo das termoelétricas como complementação das hidrelétricas.

((o))eco: O Ministério de Minas e Energia estuda usar as termelétricas de forma permanente, para poupar os reservatórios. O que o senhor acha disso?
Utilizar termelétricas para complementar o sistema hidrelétrico é uma solução equivocada. Em primeiro lugar, estamos falando de um sistema elétrico que prioriza a geração de energia a partir da água, o que o torna dependente do regime hidrológico. É preciso com urgência diversificar a matriz de eletricidade do Brasil, utilizando fontes que, ao mesmo tempo, possam complementar o regime da falta de água e que sejam viáveis do ponto de vista econômico e ambiental.

((o))eco: Por quê?
Primeiro, porque a termoeletricidade pode custar 4 vezes mais do que a hidroeletricidade. Além disso, utiliza três fontes fósseis derivados de petróleo: óleo combustível, carvão mineral e gás natural. O principal problema na utilização das fontes fósseis, ao meu entender, não são as emissões de gases de efeito estufa. No caso brasileiro, o problema maior das termoelétricas é serem emissoras de hidrocarbonetos, de dióxido de nitrogênio, de dióxido de enxofre, de material particulado e de fumaça.

((o))eco: Quais são as consequências?
O impacto ambiental dessas fontes é sobre a saúde pública. A vizinhança dessas usinas fica suscetível a doenças crônicas causadas por esse coquetel de poluição.

((o))eco: Há termelétricas que utilizam água na sua refrigeração. Isso causa impactos negativos?
Em geral, essas usinas utilizam água dos rios próximos. Existem regiões no Brasil em que o comprometimento hídrico impede a construção de termelétricas. No estado de São Paulo, no rio Piracicaba, por exemplo, não foi possível construir usinas a gás natural porque elas demandavam um volume de água além das possibilidades da bacia deste rio.

((o)) eco: Qual é o custo das termelétricas?

A partir do bagaço da cana de açúcar, resíduo da produção sucroalcooleira, pode-se produzir 10 mil megawatts excedentes, o que equivale a mais de 2 vezes a energia média produzida por Belo Monte.

A energia das termelétricas pode custar até 4 vezes mais do que a hidroeletricidade. Ao mesmo tempo, com a Medida Provisória 579, o governo quer reduzir a tarifa de energia usando recursos do Tesouro Nacional. É um absurdo, pois esta medida afeta indiretamente o bolso dos consumidores. Somos nós que vamos pagar por essa redução da tarifa. É uma forma fictícia de fazer algo desejável: reduzir a tarifa. Temos uma das tarifas de energia elétrica mais cara do mundo, algo absurdo porque nossa matriz com ênfase em hidrelétricas produz energia que deveria ser barata.

((o))eco: E quais seriam essas alternativas?
São três: a conservação da energia, o uso da biomassa e da energia eólica. A primeira alternativa é pensar na conservação e no uso eficiente da energia. É preciso uma ampla campanha nas mídias para ensinar à população a reduzir o desperdício. O governo está fazendo o contrário, quando diz que não há risco de racionamento.

Quando o governo prefere a termoeletricidade como base, está dizendo: vamos usar a termoeletricidade de forma que não se tenha riscos durante o período em que a hidrologia é desfavorável, que é o período entre junho e outubro. Essa solução, como já pontuei antes, é completamente inadequada.

A campanha por redução do consumo de energia deve abranger também grandes consumidores industriais. Estou falando de 6 setores: cimento, siderurgia, alumínio, química, ferro-liga e papel/celulose. Em conjunto, eles respondem pelo consumo de 30% da energia no Brasil. Não estou falando em fechar essas fábricas, mas que um esforço desses setores na redução da sua escala de produção aumentaria a disponibilidade de energia para a economia e para a população. É uma questão de interesse público.

((o))eco: E a segunda alternativa?

No mês de outubro, por causa do regime hidrológico, a capacidade de geração ficará reduzida a 1mil megawatts, ou seja, 10 % da capacidade instalada.

A segunda alternativa é a utilização do potencial do setor sucroalcooleiro como fonte de complementação de energia. O Instituto de Eletrotécnica e Energia da USP recentemente constatou que, a partir do bagaço da cana de açúcar, resíduo da produção sucroalcooleira, pode-se produzir 10 mil megawatts excedentes, o que equivale a mais de 2 vezes a energia média produzida por Belo Monte. Essa energia pode chegar ao sistema elétrico em 3 ou 4 meses e a custo baixo.

Hoje, o bagaço é utilizado para complementar a própria necessidade de eletricidade das usinas. Mas elas também poderiam comercializar o excedente que é dessa ordem que eu falei, de 10 mil megawatts. Elas já comercializam 1.230 megawatts de energia elétrica excedente.

((o))eco: Por que essa energia não está disponível?
Uma resolução da Aneel (Agência Nacional de Energia Elétrica) determina que cabe à usina o investimento para construir as linhas de transmissão de energia que levem esse excedente da usina até uma subestação ou uma rede de distribuição de energia elétrica. Nosso levantamento, feito para algumas regiões, mostra que a distância entre as usinas e a rede varia de 10 a 30 km, percurso relativamente curto.

((o)) eco: E o que poderia ser feito para viabilizar estas pequenas linhas?
O BNDES (Banco Nacional de Desenvolvimento) poderia financiar a construção dessas linhas. Com crédito, esse excedente poderia estar disponível já na próxima safra, em abril de 2013. Com investimento na troca de equipamentos de cogeração ─ caldeiras de maior pressão ─ esses 10 mil megawatts potenciais da biomassa podem dobrar para 20 mil megawatts. De novo, em nome do interesse público, o BNDES poderia ser o financiador.

Infelizmente, o BNDES está usando 22,5 bilhões de reais para financiar a construção da usina hidrelétrica de Belo Monte. Quando ficar pronta, em 2019, ela acrescentará apenas 4.400 megawatts médios ao sistema elétrico. Veja o absurdo, a política do governo prioriza megaobras de hidrelétricas, quando existem soluções de energia complementar às hidros, que funcionam justamente na época das secas. A safra da cana de açúcar ocorre no período de menos chuvas, que vai de maio até novembro.

((o))eco: Belo Monte deveria ser descartado, então?

Conforme dados oficiais, o sistema de transmissão e distribuição nacional tem uma perda técnica (excluindo os gatos) da ordem de 15,4%.

Belo Monte deveria ser descartada. O custo é enorme: 30 bilhões de reais para uma capacidade instalada de 11.233 megawatts. Essa capacidade estará disponível durante 3 ou 4 meses por ano, no período das chuvas. No mês de outubro, por causa do regime hidrológico, a capacidade de geração ficará reduzida a 1mil megawatts, ou seja, 10 % da capacidade instalada. A média ao longo do ano é de 4400 megawatts. A contribuição do rio Xingu e da Usina de Belo Monte é uma fração do que está sendo alegado para justificar a construção da usina. Eu afirmo, Belo Monte atende ao interesse das empreiteiras e empresas ligadas à sua construção, e não à população e a economia brasileira.

((o))eco: E a terceira alternativa?
A terceira alternativa é a energia eólica. No nordeste, o regime de ventos é maior justamente na época da estiagem. Os reservatórios do rio São Francisco podem acumular água durante o período mais crítico, enquanto a energia eólica abasteceria a região nordeste. Ouve-se a alegação de que a biomassa, a eólica, são fontes intermitentes. Ora, a hidroeletricidade também é intermitente, pois depende do regime hidrológico.

((o))eco: E quanto a eficiência, qual é o percentual de perda nas linhas de transmissão?
Conforme dados oficiais, o sistema de transmissão e distribuição nacional tem uma perda técnica (excluindo os gatos) da ordem de 15,4%. É impossível eliminar todas as perdas, mas cortar 5 pontos percentuais é tecnologicamente viável e traz grandes benefícios econômicos. Basta investir na manutenção do sistema: isolar melhor os fios de transmissão e trocar transformadores que já esgotaram sua vida útil. O número crescente de apagões é uma evidência de má manutenção. Por exemplo, parafusos velhos levam à queda de torres de transmissão.

Dessa forma, a perda poderia ser reduzida para cerca de 10% e acrescentariam ao sistema elétrico o equivalente a uma usina hidrelétrica de 6.100 megawatts ─ 150% mais da média de Belo Monte ─ de acordo com cálculo recente que fiz com estudantes da Pós-Graduação em Energia do IEE. Isso poderia ser alcançado a um terço do custo de produzir um novo megawatt.

A Aneel é leniente em relação às perdas. É fundamental que ela defina, em nome do interesse público, metas de redução de perdas técnicas nas empresas de distribuição e concessionárias de distribuição de energia. O alcance dessas metas deveria ser associado à redução tarifária.

((o))eco: É caro construir novas linhas de transmissão?
Sim, principalmente para levar energia distante dos centros de consumo, como é o caso dos projetos de hidrelétricas que estão sendo construídas na Amazônia.

((o))eco: E a energia nuclear? O Brasil deve pensar em investir nesta alternativa de energia?
A energia nuclear é uma fonte cara, desnecessária e com um risco de ocorrência de acidentes severos. Além das usinas de Angra 1 e 2, estamos construindo Angra 3. Todas elas numa região que é imprópria para a implantação de usinas nucleares. Angra dos Reis é uma região suscetível a grandes chuvas no verão. Não é impensável a possibilidade que uma chuva mais severa derrube as linhas que transmitem energia elétrica do sistema até as usinas.

O resultado da interrupção de fornecimento de energia elétrica pode fazer as bombas de refrigeração de água dos reatores pararem, provocando o superaquecimento e a explosão do reator, que foi o que aconteceu, em fevereiro de 2011, nos 4 reatores de Fukushima, no Japão. Com um agravante: a única via de escoamento da população é a Rio-Santos, absolutamente incapaz de evacuar toda a população local. A empresa Eletronuclear considera, hoje, uma população da ordem de 200 mil habitantes. Essa população dobra na época das férias, que coincide com a época das chuvas.
