‘When in Rome’: Monkeys Found to Conform to Social Norms (Science Daily)

Apr. 25, 2013 — The human tendency to adopt the behaviour of others when on their home territory has been found in non-human primates.

Researchers at the University of St Andrews observed ‘striking’ fickleness in male monkeys, when it comes to copying the behaviour of others in new groups. The findings could help explain the evolution of our human desire to seek out ‘local knowledge’ when visiting a new place or culture.

The new discovery was made by Dr Erica van de Waal and Professor Andrew Whiten of the University of St Andrews, along with Christèle Borgeaud of the University of Neuchâtel.

Professor Whiten commented, “As the saying goes, ‘When in Rome, do as the Romans do’. Our findings suggest that a willingness to conform to what all those around you are doing when you visit a different culture is a disposition shared with other primates.”

The research was carried out by observing wild vervet monkeys in South Africa. The researchers originally set out to test how strongly wild vervet monkey infants are influenced by their mothers’ habits.

But more interestingly, they found that adult males migrating to new groups conformed quickly to the social norms of their new neighbours, whether it made sense to them or not.

Professor Whiten commented, “The males’ fickleness is certainly a striking discovery. At first sight their willingness to conform to local norms may seem a rather mindless response — but after all, it’s how we humans often behave when we visit different cultures.

“It may make sense in nature, where the knowledge of the locals is often the best guide to what are the optimal behaviours in their environment, so copying them may actually make a lot of sense.”

In the initial study, the researchers provided each of two groups of wild monkeys with a box of maize corn dyed pink and another dyed blue. The blue corn was made to taste repulsive and the monkeys soon learned to eat only pink corn. Two other groups were trained in this way to eat only blue corn.

A new generation of infants were later offered both colours of food — neither tasting badly — and the adult monkeys present appeared to remember which colour they had previously preferred.

Almost every infant copied the rest of the group, eating only the one preferred colour of corn.

The crucial discovery came when males began to migrate between groups during the mating season.

The researchers found that of the ten males who moved to groups eating a different coloured corn to the one they were used to, all but one switched to the new local norm immediately.

The one monkey who did not switch, was the top ranking in his new group who appeared unconcerned about adopting local behavior.

Dr van de Waal conducted the field experiments at the Inkawu Vervet Project in the Mawana private game reserve in South Africa. She became familiar with all 109 monkeys, making it possible for her to document the behaviour of the males who migrated to new groups.

She said, “The willingness of the immigrant males to adopt the local preference of their new groups surprised us all. The copying behaviour of both the new, naïve infants and the migrating males reveals the potency and importance of social learning in these wild primates, extending even to the conformity we know so well in humans.”

Commenting on the research, leading primatologist Professor Frans de Waal, of the Yerkes Primate Center of Emory University, said that the study “is one of the few successful field experiments on cultural transmission to date, and a remarkably elegant one at that.”

The study has been hailed by leading primate experts as rare experimental proof of ‘cultural transmission’ in wild primates to date. The research is published April 25 by the journalScience.

Segunda, 22 Abril 2013 18:34 Última modificação em Terça, 23 Abril 2013 13:14|

Governo federal montará força-tarefa para o cadastro de novas famílias beneficiárias do programa. Ação ocorrerá em seis regiões do Pará

SOPHIA GEBRIM

O Ministério do Meio Ambiente (MMA) pretende ampliar o número de beneficiários do Programa de Apoio à Conservação Ambiental Bolsa Verde. Nesta segunda-feira (22), representantes do Ministério, do Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio), do Ministério do Desenvolvimento Social e Combate à Fome (MDS), do Instituto Nacional de Colonização e Reforma Agrária (Incra) e da Secretaria do Patrimônio da União (SPU) participaram de oficina, em Belém (PA), para definir mutirões para cadastramento de novas famílias beneficiárias no Pará.

O Bolsa Verde é um programa do Plano Brasil sem Miséria voltado a famílias em situação de extrema pobreza que exercem atividades de conservação ambiental. O objetivo é incentivar a conservação dos ecossistemas, promover a cidadania e aumentar a renda das populações que vivem em unidades de conservação, assentamentos e povos ribeirinhos. O valor do benefício do Bolsa Verde é de R$ 300 – pagos a cada três meses para famílias inseridas no Cadastro Único (CadÚnico) dos programas sociais do governo federal.

“Com base na análise de dados potenciais para o Bolsa Verde, verificamos que 40% das famílias cadastradas pelo ICMBio e Incra, não encontradas no CadÚnico do Plano Brasil Sem Miséria, estão localizadas no Estado do Pará”, destacou a representante da Secretaria de Extrativismo e Desenvolvimento Rural Sustentável do MMA, Larisa Gaivizzo. Dessa forma, com base na análise de critérios quantitativos e logísticos para a realização de mutirões para alcançar as famílias com potencial de beneficiárias, foram selecionados seis polos para força-tarefa nas seguintes regiões: Santarém, Afuá, Porto de Moz e Gurupá, Marajó, Baixo Tocantins e Salgado Paraense.

Os mutirões ocorrerão nos próximos meses, entre maio e junho, e farão o CadÚnico para os programas Bolsa Verde e Bolsa Família, ambas ações do Plano Brasil Sem Miséria do governo federal. Nessas mesmas regiões também serão agregados outros serviços de apoio à população local, que ainda serão negociados e definidos em reunião interministerial nos próximos dias.

Além disso, os mutirões somarão força à outras atividades desenvolvidas nessas regiões pelo ICMBio, como o cadastramento de famílias em Unidades de Conservação (UCs) de uso sustentável.

Anthropologists should do a better job of promoting their field (Orlando Sentinel)

By Ty Matejowsky and Beatriz M. Reyes-Foster | Guest columnists

April 24, 2013

Anthropology has been in the news quite a bit lately.

The New York Times recently profiled Napoleon Chagnon on the eve of the publication of his memoir, “Noble Savages: My Life Among Two Dangerous Tribes — The Yanomamo and the Anthropologists.”

Last August, Kiplinger named anthropology “the worst major for your career.”

Two months later, Forbes ranked “anthropology and archaeology,” as No. 1 on its list of “worst college majors.”

This newfound public shaming of anthropology only adds insult to injury in light of Florida Gov. Rick Scott‘s dismissive 2011 statements about anthropologists. More than once Scott, whose daughter famously earned an anthropology degree, quipped that Florida does “not need any more anthropologists.”

Overall, 2012 was anthropology’s annus horribilis, as Science magazine recently stated.

Of anthropology’s major subfields, cultural anthropology has probably fared the worst in recent public discussions. Although archaeology and physical anthropology get their fair share of positive media portrayals — think Emily Deschanel’s portrayal of sexy forensic anthropologist Temperance Brennan on CBS’s Bones — it seems that journalists only acknowledge cultural anthropology when it is gripped by controversy.

Cultural anthropology suffers a public-image problem as our “brand” is now largely defined by others. Politicians, studies by business media with profit-driven measures of success, and pseudo-anthropological authorities like Jared Diamond have done much to define cultural anthropology in the popular consciousness.

In many ways, cultural anthropology lacks archaeology’s and physical anthropology’s “cool” cachet. While their practices and methodologies easily translate to National Geographic or History Channel programs, they necessarily involve some degree of commodification.

Bones, ruins, and artifacts all become objects for public consumption. Cultural anthropology is much more difficult to “sell” because it resists similarly commodifying living people. The 2013 Sports Illustrated swimsuit issue with photos of tribal peoples alongside bikini-clad models serves as a prime example of this commodification.

Many cultural anthropologists have remained aloof amid this tumult. This remoteness is surely compounded by today’s academic environment. Public engagement counts little toward promotion and tenure and may even be viewed dismissively by fellow academics.

Many anthropologists, already burdened with increased class sizes, decreased institutional support, and ever-growing pressures to publish and secure research grants simply do not have the time, resources or motivation to publicly voice their opinions.

Cultural anthropology’s branding problem is largely superficial. Anthropologists possess unique knowledge and skill sets that have real-world value. Anthropology helps us understand the world in a way that cannot be reduced to numbers or captured in surveys.

The marketing industry is increasingly recognizing the value of anthropological methodologies. A recent Atlantic article highlights the way in which ethnography and participant-observation are used in market research. Moreover, the World Bank recently elected an anthropologist, Jim Yong Kim, as president.

Anthropologists need to take better ownership of our brand. The complexity of anthropological concepts such as “culture,” “power” and the “global” should not dissuade anthropologists from engaging in meaningful public discourse.

Evidence of such newfound public engagement is emerging within the Web and blogosphere. Jason Antrosio’s Living Anthropologically blog and the “This is Anthropology” initiative, a “jargon-free” website with the purpose of informing the public about anthropology, are well ahead of the curve in this way, providing anthropological perspectives on relevant social issues that are both accessible and engaging.

Revisiting anthropology’s history may be the best way to revitalize the cultural anthropology brand. Franz Boas, considered the father of American anthropology, argued that race is not biologically determined and that no race is genetically superior. His numerous speeches and public writings underscore his commitment to public engagement.

Margaret Mead and Ruth Benedict continued Boas’ tradition by writing books read by millions. Mead’s “Coming of Age in Samoa” pushed gender and sex boundaries in the 1920s. Benedict’s book “The Chrysanthemum and the Sword” transformed many people’s’ understandings of post-war Japan.

The much-loved fictional writing of Zora Neale Hurston was greatly informed by her anthropological training. These anthropologists, perhaps imperfectly, challenged prevailing assumptions by the general public in their times.

Challenging preconceived notions and assumptions is still central to our brand. Anthropology is critically engaged, proactive, holistic and progressive. More than anything, the anthropology brand is concerned with culture, an ever-changing process that both defines our reality and is defined by our individual and societal choices.

Anthropologists at the All Scientists Meeting of the Long Term Ecological Research Network (Anthropology News)

In September 2012, we participated in the 2012 All Scientists Meeting (ASM) of the Long Term Ecological Research (LTER) Network in Estes Park, Colorado to make the case for integrating more anthropologists into the study of ecosystems. During the ASM’s initial plenary, the presence of embedded anthropologists was announced to all, and we were invited to stand and identify ourselves for the audience. From then on we spent several days immersing ourselves in the activities of the LTER network and engaging with its researchers, a group previously unknown to many of us. We worked to overcome apprehensions (“Why are anthropologists studying us?”), identify areas where our expertise might be useful (“What can anthropologists contribute to ecological research?”), and left with some experiences and ideas that we would like to share with fellow anthropologists who may be interested in pursuing the challenges and opportunities provided by the LTER network.

The LTER Network

The National Science Foundation (NSF) created the LTER Network in 1980 to support long-term research of ecosystems with the understanding that many ecosystem processes can only be studied through long-term research. Sites were selected to represent major ecosystem types or natural biomes across the US (there are now also a few international LTER sites). It is one of the most highly funded NSF programs. The LTER Network is a major component of the LTER program as it allows for integrative cross-site, and network-wide research. The ASM is another critical component of the network as it brings researchers, post-docs, graduate and undergraduate students together every three years to share results, discuss progress, and develop new collaborative research projects. The ASMconsists of an intensive six-day program with workshops, keynote speakers, poster presentations (with free beer) and field trips, which all offer plenty of opportunities to strengthen and develop new connections and opportunities within the network.

Anthropologists at the ASM

Anthropologists (eg, Ted Gragson, Laura Ogden, Charles Redman) have been involved in research at a number of the LTER sites and have written about the integration of social science in the LTER network (Redman et al, Integrating Social Science into the Long-Term Ecological Research [LTER] Network, Ecosystems, 2004), but the theme of this year’s ASM meeting—the Anthropocene—offered a unique opportunity to make the case for greater involvement of anthropologists in LTER projects. And so with support of the cultural anthropology program at NSF, Steve Lansing gave a keynote lecture about his research on complex adaptive systems in Bali, while Michael Agar and Michael Paolisso organized two workshops to identify intellectual and programmatic bridges between ecological and environmental anthropology and LTER projects to strengthen research into ecological and human dimension interactions at multiple spatiotemporal scales. The workshops showcased our research, which represented a wide range of theoretical and methodological approaches within ecological anthropology, but all underscored the relevance of anthropological approaches for study of complex social-ecological systems in the Anthropocene. In addition, we participated in workshops, visited the poster sessions, and made connections with LTER researchers. Most researchers at our session were already studying the human dimensions of ecosystems, which is indicative of some the challenges in integrating anthropology.

There is a growing recognition among ecologists that they need to grapple with the human impacts on ecosystems and that the old model of studying isolated and protected reserves to understand ecosystems is no longer valid. This is evidenced by the theme of this year’s ASM meeting and the increasing impact of climate change on ecosystems in the LTER sites. However, there are few ecological models that satisfactorily incorporate human complexity. Ecologists may study ecosystem processes at the micro-scale and then jump to the global macro-scale, eg, measuring the impact of global warming on these processes, thus skipping the local, regional, and national scales at which human activities more directly affect ecosystem processes in myriad ways. This offers opportunities for anthropologists who study complex social-ecological systems using a holistic approach and making linkages across these spatiotemporal scales. Moreover, anthropologists are no strangers to long-term research as many are involved in ethnographic research in one site over multiple decades. Thus, anthropologists can make significant conceptual contributions to LTER projects.

Opportunities

One attraction of research in LTER sites is that anthropologists living close to an LTER site could do research in their own backyard. There are currently 26 sites across the US so there are plenty of opportunities. In addition, it offers the possibility of funding sources other than the NSF Cultural Anthropology program. However, funding processes are complicated and opportunities may be more limited (than they should be). There are some funding restrictions within NSF that limit the integration of social and ecological research. There are no clear guidelines or processes for funding social science research within LTER projects. Senior anthropologists may have to find other sources of funding to support their research at LTER sites. However, we found that there may be many more opportunities for enterprising graduate students to join an LTER team. The advantage for graduate students is that LTER sites have extensive data and an established infrastructure, which relieves them of some of the challenges of finding a new field site and provides ample opportunity to collaborate with other graduate students, more effectively bridging interdisciplinary divides.

The research model of the LTER network—long-term projects, cross-site linkages, and consistent funding—also offers unique opportunities for anthropologists to rethink ways of doing research in unprecedented ways. Whereas long-term ethnographic research often depends on the commitment of individual researchers, research at LTER sites is institutionalized. We could ask, what comprehensive, long-term, high frequency data on social systems could be collected across multiple sites to advance our understanding of the dynamic processes in coupled human and natural systems? That is an exciting question to ponder.

Challenges

While there are social science activities at almost all LTER sites and the network has a long history of social science engagement, it is often on an ad hoc and inconsistent basis and contingent on funding availability. The greatest challenge in integrating anthropological research in LTER projects may be a general problem of interdisciplinary research. This is manifested in different ways, including the incongruence of conceptual models, theories, methods, scope, and units of analysis in ecology and anthropology. Anthropologists’ primary goal has been describing and explaining cross-cultural variation across all human societies and very long time periods, while LTER research is mainly conducted within the context of the US and over relatively short periods (even though it is long-term research). In addition, the iterative, recursive, abductive approaches of ethnographic research strategies, as described by Michael Agar, are not always understood by ecologists who use more standardized scientific protocols and can be seen as lacking value and validity. Of course, there are many ecologists and anthropologists that have successfully collaborated in interdisciplinary studies of complex social-ecological systems, for example the South Turkana Ecosystem Project, but the number of transdisciplinary studies in which research transcends the disciplines is less common.

Conclusion

Of course, being anthropologists, we could not help ourselves and studied the LTER participants at their ASM. If we want to make the case for integrating more anthropologists in the study of ecosystems, we should at least become familiar with what ecologists think of our research and us. The audience at our workshops consisted primarily of fellow anthropologists, ecology graduate students, and a few PIs of LTER sites, which indicates that among the higher organizational levels of the LTER network and the next generation of ecologists there is a growing interest in anthropological approaches to study anthromes in the Anthropocene. However, there still may be some resistance to the integration of social sciences in ecosystem research as well as stereotypes of anthropologists, and we overheard a senior ecologist describe anthropologists as being lousy scientists with physics envy and no quantitative skills who want a slice of the LTER cake. To be fair, Lansing’s keynote was well-received by the ecologists in the audience, who for the most part were excited to see how topics that interested them were interwoven with topics more familiar to anthropologists, including religion, social relations, economic development, and governance.

In the end, one keynote and two workshops are not sufficient to make the case for anthropology, but it is a necessary first step and we think that an ongoing engagement with LTER research is critical if we want to contribute to a discussion about Earth stewardship.

What BP Doesn’t Want You to Know About the 2010 Gulf Spill (The Daily Beast)

The 2010 Gulf of Mexico oil spill was even worse than BP wanted us to know.

by  | April 22, 2013 4:45 AM EDT

“It’s as safe as Dawn dishwashing liquid.” That’s what Jamie Griffin says the BP man told her about the smelly, rainbow-streaked gunk coating the floor of the “floating hotel” where Griffin was feeding hundreds of cleanup workers during the BP oil disaster in the Gulf of Mexico. Apparently, the workers were tracking the gunk inside on their boots. Griffin, as chief cook and maid, was trying to clean it. But even boiling water didn’t work.

“The BP representative said, ‘Jamie, just mop it like you’d mop any other dirty floor,’” Griffin recalls in her Louisiana drawl.

It was the opening weeks of what everyone, echoing President Barack Obama, was calling “the worst environmental disaster in American history.” At 9:45 p.m. local time on April 20, 2010, a fiery explosion on the Deepwater Horizon oil rig had killed 11 workers and injured 17. One mile underwater, the Macondo well had blown apart, unleashing a gusher of oil into the gulf. At risk were fishing areas that supplied one third of the seafood consumed in the U.S., beaches from Texas to Florida that drew billions of dollars’ worth of tourism to local economies, and Obama’s chances of reelection. Republicans were blaming him for mishandling the disaster, his poll numbers were falling, even his 11-year-old daughter was demanding, “Daddy, did you plug the hole yet?”

Griffin did as she was told: “I tried Pine-Sol, bleach, I even tried Dawn on those floors.” As she scrubbed, the mix of cleanser and gunk occasionally splashed onto her arms and face.

Within days, the 32-year-old single mother was coughing up blood and suffering constant headaches. She lost her voice. “My throat felt like I’d swallowed razor blades,” she says.

Then things got much worse.

Like hundreds, possibly thousands, of workers on the cleanup, Griffin soon fell ill with a cluster of excruciating, bizarre, grotesque ailments. By July, unstoppable muscle spasms were twisting her hands into immovable claws. In August, she began losing her short-term memory. After cooking professionally for 10 years, she couldn’t remember the recipe for vegetable soup; one morning, she got in the car to go to work, only to discover she hadn’t put on pants. The right side, but only the right side, of her body “started acting crazy. It felt like the nerves were coming out of my skin. It was so painful. My right leg swelled—my ankle would get as wide as my calf—and my skin got incredibly itchy.”

“These are the same symptoms experienced by soldiers who returned from the Persian Gulf War with Gulf War syndrome,” says Dr. Michael Robichaux, a Louisiana physician and former state senator, who treated Griffin and 113 other patients with similar complaints. As a general practitioner, Robichaux says he had “never seen this grouping of symptoms together: skin problems, neurological impairments, plus pulmonary problems.” Only months later, after Kaye H. Kilburn, a former professor of medicine at the University of Southern California and one of the nation’s leading environmental health experts, came to Louisiana and tested 14 of Robichaux’s patients did the two physicians make the connection with Gulf War syndrome, the malady that afflicted an estimated 250,000 veterans of that war with a mysterious combination of fatigue, skin inflammation, and cognitive problems.

Meanwhile, the well kept hemorrhaging oil. The world watched with bated breath as BP failed in one attempt after another to stop the leak. An agonizing 87 days passed before the well was finally plugged on July 15. By then, 210 million gallons of Louisiana sweet crude had escaped into the Gulf of Mexico, according to government estimates, making the BP disaster the largest accidental oil leak in world history.

In 2010, Pulitzer Prize-winning animator Mark Fiore created this humorous and poignant take on the BP oil spill.

Yet three years later, the BP disaster has been largely forgotten, both overseas and in the U.S. Popular anger has cooled. The media have moved on. Today, only the business press offers serious coverage of what the Financial Times calls “the trial of the century”—the trial now under way in New Orleans, where BP faces tens of billions of dollars in potential penalties for the disaster. As for Obama, the same president who early in the BP crisis blasted the “scandalously close relationship” between oil companies and government regulators two years later ran for reelection boasting about how much new oil and gas development his administration had approved.

Such collective amnesia may seem surprising, but there may be a good explanation for it: BP mounted a cover-up that concealed the full extent of its crimes from public view. This cover-up prevented the media and therefore the public from knowing—and above all, seeing—just how much oil was gushing into the gulf. The disaster appeared much less extensive and destructive than it actually was. BP declined to comment for this article.

That BP lied about the amount of oil it discharged into the gulf is already established. Lying to Congress about that was one of 14 felonies to which BP pleaded guilty last year in a legal settlement with the Justice Department that included a $4.5 billion fine, the largest fine ever levied against a corporation in the U.S.

What has not been revealed until now is how BP hid that massive amount of oil from TV cameras and the price that this “disappearing act” imposed on cleanup workers, coastal residents, and the ecosystem of the gulf. That story can now be told because an anonymous whistleblower has provided evidence that BP was warned in advance about the safety risks of attempting to cover up its leaking oil. Nevertheless, BP proceeded. Furthermore, BP appears to have withheld these safety warnings, as well as protective measures, both from the thousands of workers hired for the cleanup and from the millions of Gulf Coast residents who stood to be affected.

The financial implications are enormous. The trial now under way in New Orleans is wrestling with whether BP was guilty of “negligence” or “gross negligence” for the Deepwater Horizon disaster. If found guilty of “negligence,” BP would be fined, under the Clean Water Act, $1,100 for each barrel of oil that leaked. But if found guilty of “gross negligence”—which a cover-up would seem to imply—BP would be fined $4,300 per barrel, almost four times as much, for a total of $17.5 billion. That large a fine, combined with an additional $34 billion that the states of Louisiana, Alabama, Mississippi, and Florida are seeking, could have a powerful effect on BP’s economic health.

Yet the most astonishing thing about BP’s cover-up? It was carried out in plain sight, right in front of the world’s uncomprehending news media (including, I regret to say, this reporter).

The chief instrument of BP’s cover-up was the same substance that apparently sickened Jamie Griffin and countless other cleanup workers and local residents. Its brand name is Corexit, but most news reports at the time referred to it simply as a “dispersant.” Its function was to attach itself to leaked oil, break it into droplets, and disperse them into the vast reaches of the gulf, thereby keeping the oil from reaching Gulf Coast shorelines. And the Corexit did largely achieve this goal.

But the 1.84 million gallons of Corexit that BP applied during the cleanup also served a public-relations purpose: they made the oil spill all but disappear, at least from TV screens. By late July 2010, the Associated Press and The New York Times were questioning whether the spill had been such a big deal after all. Time went so far as to assert that right-wing talk-radio host Rush Limbaugh “has a point” when he accused journalists and environmentalists of exaggerating the crisis.

But BP had a problem: it had lied about how safe Corexit is, and proof of its dishonesty would eventually fall into the hands of the Government Accountability Project, the premiere whistleblower-protection group in the U.S. The proof? A technical manual BP had received from NALCO, the firm that supplied the Corexit that BP used in the gulf.

An electronic copy of that manual is included in a new report GAPhas issued, “Deadly Dispersants in the Gulf.” On the basis of interviews with dozens of cleanup workers, scientists, and Gulf Coast residents, GAP concludes that the health impacts endured by Griffin were visited upon many other locals as well. What’s more, the combination of Corexit and crude oil also caused terrible damage to gulf wildlife and ecosystems, including an unprecedented number of seafood mutations; declines of up to 80 percent in seafood catch; and massive die-offs of the microscopic life-forms at the base of the marine food chain. GAP warns that BP and the U.S. government nevertheless appear poised to repeat the exercise after the next major oil spill: “As a result of Corexit’s perceived success, Corexit … has become the dispersant of choice in the U.S. to ‘clean up’ oil spills.”

BP’s cover-up was not planned in advance but devised in the heat of the moment as the oil giant scrambled to limit the PR and other damages of the disaster. Indeed, one of the chief scandals of the disaster is just how unprepared both BP and federal and state authorities were for an oil leak of this magnitude. U.S. law required that a response plan be in place before drilling began, but the plan was embarrassingly flawed.

“We weren’t managing for actual risk; we were checking a box,” says Mark Davis, director of the Institute on Water Resources Law and Policy at Tulane University. “That’s how we ended up with a response plan that included provisions for dealing with the impacts to walruses: because [BP] copied word for word the response plans that had been developed after the Exxon-Valdez oil spill [in Alaska, in 1989] instead of a plan tailored to the conditions in the gulf.”

As days turned into weeks and it became obvious that no one knew how to plug the gushing well, BP began insisting that Corexit be used to disperse the leaking oil. This triggered alarms from scientists and from a leading environmental NGO in Louisiana, the Louisiana Environmental Action Network (LEAN).

The group’s scientific adviser, Wilma Subra, a chemist whose work on environmental pollution had won her a “genius grant” from the MacArthur Foundation, told state and federal authorities that she was especially concerned about how dangerous the mixture of crude and Corexit was: “The short-term health symptoms include acute respiratory problems, skin rashes, cardiovascular impacts, gastrointestinal impacts, and short-term loss of memory,” she told GAP investigators. “Long-term impacts include cancer, decreased lung function, liver damage, and kidney damage.”

(Nineteen months after the Deepwater Horizon explosion, a scientific study published in the peer-reviewed journal Environmental Pollution found that crude oil becomes 52 times more toxic when combined with Corexit.)

BP even rebuffed a direct request from the administrator of the Environmental Protection Agency, Lisa Jackson, who wrote BP a letter on May 19, asking the company to deploy a less toxic dispersant in the cleanup. Jackson could only ask BP to do this; she could not legally require it. Why? Because use of Corexit had been authorized years before under the federal Oil Pollution Act.

In a recent interview, Jackson explains that she and other officials “had to determine, with less-than-perfect scientific testing and data, whether use of dispersants would, despite potential side effects, improve the overall situation in the gulf and coastal ecosystems. The tradeoff, as I have said many times, was potential damage in the deep water versus the potential for larger amounts of undispersed oil in the ecologically rich coastal shallows and estuaries.” She adds that the presidential commission that later studied the BP oil disaster did not fault the decision to use dispersants.

Knowing that EPA lacked the authority to stop it, BP wrote back to Jackson on May 20, declaring that Corexit was safe. What’s more, BP wrote, there was a ready supply of Corexit, which was not the case with alternative dispersants. (A NALCO plant was located just 30 miles west of New Orleans.)

But Corexit was decidedly not safe without taking proper precautions, as the manual BP got from NALCO spelled out in black and white. The “Vessel Captains Hazard Communication” resource manual, which GAP shared with me, looks innocuous enough. A three-ring binder with a black plastic cover, the manual contained 61 sheets, each wrapped in plastic, that detailed the scientific properties of the two types of Corexit that BP was buying, as well as their health hazards and recommended measures against those hazards.

BP applied two types of Corexit in the gulf. The first, Corexit 9527, was considerably more toxic. According to the NALCO manual, Corexit 9527 is an “eye and skin irritant. Repeated or excessive exposure … may cause injury to red blood cells (hemolysis), kidney or the liver.” The manual adds: “Excessive exposure may cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects.” It advises, “Do not get in eyes, on skin, on clothing,” and “Wear suitable protective clothing.”

When available supplies of Corexit 9527 were exhausted early in the cleanup, BP switched to the second type of dispersant, Corexit 9500. In its recommendations for dealing with Corexit 9500, the NALCO manual advised, “Do not get in eyes, on skin, on clothing,” “Avoid breathing vapor,” and “Wear suitable protective clothing.”

It’s standard procedure—and required by U.S. law—for companies to distribute this kind of information to any work site where hazardous materials are present so workers can know about the dangers they face and how to protect themselves. But interviews with numerous cleanup workers suggest that this legally required precaution was rarely if ever followed during the BP cleanup. Instead, it appears that BP told NALCO to stop including the manuals with the Corexit that NALCO was delivering to cleanup work sites.

“It’s my understanding that some manuals were sent out with the shipments of Corexit in the beginning [of the cleanup],” the anonymous source tells me. “Then, BP told NALCO to stop sending them. So NALCO was left with a roomful of unused binders.”

Roman Blahoski, NALCO’s director of global communications, says: “NALCO responded to requests for its pre-approved dispersants from those charged with protecting the gulf and mitigating the environmental, health, and economic impact of this event. NALCO was never involved in decisions relating to the use, volume, and application of its dispersant.”

Misrepresenting the safety of Corexit went hand in hand with BP’s previously noted lie about how much oil was leaking from the Macondo well. As reported by John Rudolf in The Huffington Post, internal BP emails show that BP privately estimated that “the runaway well could be leaking from 62,000 barrels a day to 146,000 barrels a day.” Meanwhile, BP officials were telling the government and the media that only 5,000 barrels a day were leaking.

In short, applying Corexit enabled BP to mask the fact that a much larger amount of oil was actually leaking into the gulf. “Like any good magician, the oil industry has learned that if you can’t see something that was there, it must have ‘disappeared,’” Scott Porter, a scientist and deep-sea diver who consults for oil companies and oystermen, says in the GAP report. “Oil companies have also learned that, in the public mind, ‘out of sight equals out of mind.’ Therefore, they have chosen crude oil dispersants as the primary tool for handling large marine oil spills.”

BP also had a more direct financial interest in using Corexit, argues Clint Guidry, president of the Louisiana Shrimp Association, whose members include not only shrimpers but fishermen of all sorts. As it happens, local fishermen constituted a significant portion of BP’s cleanup force (which numbered as many as 47,000 workers at the height of the cleanup). Because the spill caused the closure of their fishing grounds, BP and state and federal authorities established the Vessels of Opportunity (VoO) program, in which BP paid fishermen to take their boats out and skim, burn, and otherwise get rid of leaked oil. Applying dispersants, Guidry points out, reduced the total volume of oil that could be traced back to BP.

“The next phase of this trial [against BP] is going to turn on how much oil was leaked,” Guidry tells me. [If found guilty, BP will be fined a certain amount for each barrel of oil judged to have leaked.] “So hiding the oil with Corexit worked not only to hide the size of the spill but also to lower the amount of oil that BP may get charged for releasing.”

Not only did BP fail to inform workers of the potential hazards of Corexit and to provide them with safety training and protective gear, according to interviews with dozens of cleanup workers, the company also allegedly threatened to fire workers who complained about the lack of respirators and protective clothing.

“I worked with probably a couple hundred different fishermen on the [cleanup],” Acy Cooper, Guidry’s second in command, tells me in Venice, the coastal town from which many VoO vessels departed. “Not one of them got any safety information or training concerning the toxic materials they encountered.” Cooper says that BP did provide workers with body suits and gloves designed for handling hazardous materials. “But when I’d talk with [the BP representative] about getting my guys respirators and air monitors, I’d never get any response.”

Roughly 58 percent of the 1.84 million gallons of Corexit used in the cleanup was sprayed onto the gulf from C-130 airplanes. The spray sometimes ended up hitting cleanup workers in the face.

“Our boat was sprayed four times,” says Jorey Danos, a 32-year-old father of three who suffered racking coughing fits, severe fatigue, and memory loss after working on the BP cleanup. “I could see the stuff coming out of the plane—like a shower of mist, a smoky color. I could see [it] coming at me, but there was nothing I could do.”

“The next day,” Danos continues, “when the BP rep came around on his speed boat, I asked, ‘Hey, what’s the deal with that stuff that was coming out of those planes yesterday?’ He told me, ‘Don’t worry about it.’ I said, ‘Man, that s–t was burning my face—it ain’t right.’ He said, ‘Don’t worry about it.’ I said, ‘Well, could we get some respirators or something, because that s–t is bad.’ He said, ‘No, that wouldn’t look good to the media. You got two choices: you can either be relieved of your duties or you can deal with it.’”

Perhaps the single most hazardous chemical compound found in Corexit 9527 is 2-Butoxyethanol, a substance that had been linked to cancers and other health impacts among cleanup workers on the 1989 Exxon-Valdez oil spill in Alaska. According to BP’s own data, 20 percent of offshore workers in the gulf had levels of 2-Butoxyethanol two times higher than the level certified as safe by the Occupational Safety and Health Administration.

Cleanup workers were not the only victims; coastal residents also suffered. “My 2-year-old grandson and I would play out in the yard,” says Shirley Tillman of the Mississippi coastal town Pass Christian. “You could smell oil and stuff in the air, but on the news they were saying it’s fine, don’t worry. Well, by October, he was one sick little fellow. All of a sudden, this very active little 2-year-old was constantly sick. He was having headaches, upper respiratory infections, earaches. The night of his birthday party, his parents had to rush him to the emergency room. He went to nine different doctors, but they treated just the symptoms; they’re not toxicologists.”

“It’s not the crime, it’s the cover-up.” Ever since the Watergate scandal of the 1970s, that’s been the mantra. Cover-ups don’t work, goes the argument. They only dig a deeper hole, because the truth eventually comes out.

But does it?

GAP investigators were hopeful that obtaining the NALCO manual might persuade BP to meet with them, and it did. On July 10, 2012, BP hosted a private meeting at its Houston offices. Presiding over the meeting, which is described here publicly for the first time, was BP’s public ombudsman, Stanley Sporkin, joining by telephone from Washington. Ironically, Sporkin had made his professional reputation during the Watergate scandal. As a lawyer with the Securities and Exchange Commission, Sporkin investigated illegal corporate payments to the slush fund that President Nixon used to buy the silence of the Watergate burglars.

Also attending the meeting were two senior BP attorneys; BP Vice President Luke Keller; other BP officials; Thomas Devine, GAP’s senior attorney on the BP case; Shanna Devine, GAP’s investigator on the case; Dr. Michael Robichaux; Dr. Wilma Subra; and Marylee Orr, the executive director of LEAN. The following account is based on my interviews with Thomas Devine, Robichaux, Subra, and Orr. BP declined to comment.

BP officials had previously confirmed the authenticity of the NALCO manual, says Thomas Devine, but now they refused to discuss it, even though this had been one of the stated purposes for the meeting. Nor would BP address the allegation, made by the whistleblower who had given the manual to GAP, that BP had ordered the manual withheld from cleanup work sites, perhaps to maintain the fiction that Corexit was safe.

“They opened the meeting with this upbeat presentation about how seriously they took their responsibilities for the spill and all the wonderful things they were doing to make things right,” says Devine. “When it was my turn to speak, I said that the manual our whistleblower had provided contradicted what they just said. I asked whether they had ordered the manual withdrawn from work sites. Their attorneys said that was a matter they would not discuss because of the pending litigation on the spill.” [Disclosure: Thomas Devine is a friend of this reporter.]

The visitors’ top priority was to get BP to agree not to use Corexit in the future. Keller said that Corexit was still authorized for use by the U.S. government and BP would indeed feel free to use it against any future oil spills.

A second priority was to get BP to provide medical treatment for Jamie Griffin and the many other apparent victims of Corexit-and-crude poisoning. This request too was refused by BP.

Robichaux doubts his patients will receive proper compensation from the $7.8 billion settlement BP reached in 2012 with the Plaintiffs’ Steering Committee, 19 court-appointed attorneys who represent the hundreds of individuals and entities that have sued BP for damages related to the gulf disaster. “Nine of the most common symptoms of my patients do not appear on the list of illnesses that settlement says can be compensated, including memory loss, fatigue, and joint and muscular pain,” says Robichaux. “So how are the attorneys going to file suits on behalf of those victims?”

At one level, BP’s cover-up of the gulf oil disaster speaks to the enormous power that giant corporations exercise in modern society, and how unable, or unwilling, governments are to limit that power. To be sure, BP has not entirely escaped censure for its actions; depending on the outcome of the trial now under way in New Orleans, the company could end up paying tens of billions of dollars in fines and damages over and above the $4.5 billion imposed by the Justice Department in the settlement last year. But BP’s reputation appears to have survived: its market value as this article went to press was a tidy $132 billion, and few, if any, BP officials appear likely to face any legal repercussions. “If I would have killed 11 people, I’d be hanging from a noose,” says Jorey Danos. “Not BP. It’s the golden rule: the man with the gold makes the rules.”

As unchastened as anyone at BP is Bob Dudley, the American who was catapulted into the CEO job a few weeks into the gulf disaster to replace Tony Hayward, whose propensity for imprudent comments—“I want my life back,” the multimillionaire had pouted while thousands of gulf workers and residents were suffering—had made him a globally derided figure. Dudley told the annual BP shareholders meeting in London last week that Corexit “is effectively … dishwashing soap,” no more toxic than that, as all scientific studies supposedly showed. What’s more, Dudley added, he himself had grown up in Mississippi and knows that the Gulf of Mexico is “an ecosystem that is used to oil.”

Nor has the BP oil disaster triggered the kind of changes in law and public priorities one might have expected. “Not much has actually changed,” says Mark Davis of Tulane. “It reflects just how wedded our country is to keeping the Gulf of Mexico producing oil and bringing it to our shores as cheaply as possible. Going forward, no one should assume that just because something really bad happened we’re going to manage oil and gas production with greater sensitivity and wisdom. That will only happen if people get involved and compel both the industry and the government to be more diligent.”

And so the worst environmental disaster in U.S. history has been whitewashed—its true dimensions obscured, its victims forgotten, its lessons ignored. Who says cover-ups never work?

Brazil worried about stadium gentrification at World Cup (Reuters)

TURIN — The Brazilian government is worried ordinary fans could be priced out of the country’s modernized stadiums in an unwanted legacy from hosting the 2014 World Cup.

Brazil is building two brand new stadiums and remodeling another 10 which will leave the country with a glut of all-seater, state-of-the-art arenas once next year’s tournament is finished.

It will be a new experience for many Brazilian fans who for years have had to put up with dilapidated arenas, dubious catering and overflowing toilets.

The worry is that many of those who provided the throbbing atmosphere at top matches will no longer be able to afford to go to games as administrators look to gentrify the soccer-going public to increase income.

“To have socially exclusive stadiums as a result of the World Cup investments is not the legacy we want,” deputy sports minister Luis Fernandes told Reuters in an interview.

“The government is very concerned with this issue and it has to be addressed very seriously. I think we could have a gentrification of the stadiums.

“Some stadium administrators are quite explicit in saying that, to be economically feasible, they would have to shift the type of attendance at games,” he added.

“It would change from one where what predominates is the so-called D and E class, to one where there will be a heavy predominance of what they call class A and B spectators who will not only buy the tickets but will also consume in the stadium.

“But if you want to shift the social origin of the spectators so you can have people that can afford to buy other merchandise and food besides tickets, that could be a negative side effect.”

Until recently, there has been almost nothing to buy inside Brazilian stadiums apart from rudimentary fast food and soft drinks. Supporters often prefer to buy counterfeit merchandise from unlicensed street vendors, known as camelos, in front of the stadium.

Nine of Brazil’s 12 World Cup stadiums are owned by the governments of the respective states and will be handed over to private administrators who will hope to make money from selling merchandise inside.

“Football had and has a very central role in building national identity in Brazil,” added Fernandes. “So we are very concerned with that aspect and will be dealing with it in terms of national and state legislation.”

A similar phenomenon has already taken place in England where stadiums have improved vastly over the past 20 years, but working-class fans have been priced out and replaced by middle-class ones.

However, while the shift in England, was built on the back of growing popularity for football, attendances at many Brazilian games are shrinking with an average of 13,000 for last year’s national championship first division.

Fans of Cruzeiro have already noticed the difference. Cheapest tickets for some of the team’s matches have cost 60 Reais ($29.87) since the re-opening of Belo Horizonte’s Mineirao stadium.

Meanwhile, cheapest tickets for the re-opening the Castelao stadium in Fortaleza cost 50 Reais for a double bill of matches in the local state championship, more than at many European first division clubs.

Fernandes pointed out that soccer had such a strong influence in Brazil that memories of the 1950 tournament, which the country hosted but the team lost to Uruguay in the deciding match, were still dragged up.

“It has deep historical, roots,” he said, explaining that Brazilians suffered from what writer Nelson Rodrigues described as “the stray dog complex”.

“Brazilians suffered an inferiority complex and when we lost that match against Uruguay, it reinforced that,” he said. “We were the stray dogs and the others were the pedigrees.

“People felt condemned to be inferior. Football was the first area which inspired national pride up, where we thought Brazil can do it.”

Playing for All Kinds of Possibilities (N.Y.Times)

Buckets of Blickets: Children and Logic: A game developed by researchers at the University of California, Berkeley hopes to show how imaginative play in children may influence development of abstract thought.

By DAVID DOBBS

Published: April 22, 2013

When it comes to play, humans don’t play around.

Alison Gopnik and the Gopnik Lab/University of California, Berkeley. Esther and Benny, both 4, play Blickets with Sophie Bridgers in a lab at the University of California, Berkeley. Children, lacking prior biases, excel in the game, based on associations, but adults flunk it.

Other species play, but none play for as much of their lives as humans do, or as imaginatively, or with as much protection from the family circle. Human children are unique in using play to explore hypothetical situations rather than to rehearse actual challenges they’ll face later. Kittens may pretend to be cats fighting, but they will not pretend to be children; children, by contrast, will readily pretend to be cats or kittens — and then to be Hannah Montana, followed by Spider-Man saving the day.

And in doing so, they develop some of humanity’s most consequential faculties. They learn the art, pleasure and power of hypothesis — of imagining new possibilities. And serious students of play believe that this helps make the species great.

The idea that play contributes to human success goes back at least a century. But in the last 25 years or so, researchers like Elizabeth S. SpelkeBrian Sutton-SmithJaak Panksepp and Alison Gopnik have developed this notion more richly and tied it more closely to both neuroscience and human evolution. They see play as essential not just to individual development, but to humanity’s unusual ability to inhabit, exploit and change the environment.

Dr. Gopnik, author of “The Scientist in the Crib” and “The Philosophical Baby,” and a professor of psychology at the University of California, Berkeley, has been studying the ways that children learn to assess their environment through play. Lately she has focused on the distinction between “exploring” new environments and “exploiting” them. When we’re quite young, we are more willing to explore, she finds; adults are more inclined to exploit.

To exploit, one leans heavily on lessons (and often unconscious rules) learned earlier — so-called prior biases. These biases are useful to adults because they save time and reduce error: By going to the restaurant you know is good, instead of the new place across town, you increase the chance that you’ll enjoy the evening.

Most adults are slow to set such biases aside; young children fling them away like bad fruit.

Dr. Gopnik shows this brilliantly with a game she invented with the psychologist David Sobel (her student, now a professor at Brown). In the game, which has the fetching name Blickets, players try to figure out what it is that makes an otherwise undistinguished clay figure a blicket. In some scenarios you can win even if you’re applying a prior bias. In others you can’t.

Last summer I joined Dr. Gopnik behind a wall of one-way glass to watch her lab manager, Sophie Bridgers, play the game with an extremely alert 4-year-old, Esther.

Seated at a child-size table, Esther leaned forward on her elbows to watch as Ms. Bridgers brought out a small bin of clay shapes and told her that some of them were blickets but most were not.

“You cannot tell which ones are blickets by looking at them. But the ones that are blickets have blicketness inside. And luckily,” Ms. Bridgers went on, holding up a box with a red plastic top, “I have my machine. Blicketness makes my machine turn on and play music.”

It’s a ruse, of course. The box responds not to the clay shapes but to a switch under the table controlled by Ms. Bridgers.

Now came the challenge. The game can be played by either of two rules, called “and” and “or.” The “or” version is easier: When a blicket is placed atop the machine, it will light the machine up whether placed there by itself or with other pieces. It is either a blicket or it isn’t; it doesn’t depend on the presence of any other object.

In the “and” trial, however, a blicket reveals its blicketness only if both it and another blicket are placed on the machine; and it will light up the box even if it and the other blicket are accompanied by a non-blicket. It can be harder than it sounds, and this is the game that Esther played.

First, Ms. Bridgers put each of three clay shapes on the box individually — rectangle, then triangle, then a bridge. None activated the machine. Then she put them on the box in three successive combinations.

1. Rectangle and triangle: No response.

2. Rectangle and bridge: Machine lighted up and played a tune!

3. Triangle and bridge: No response.

Ms. Bridgers then picked up each piece in turn and asked Esther whether it was a blicket. I had been indulging my adult (and journalistic) prior bias for recorded observation by filling several pages with notes and diagrams, and I started flipping frantically through my notebook.

I was still looking when Esther, having given maybe three seconds’ thought to the matter, correctly identified all three. The rectangle? “A blicket,” she said. Triangle? A shake of the head: No. Bridge? “A blicket.” A 4-year-old had instantly discerned a rule that I recognized only after Dr. Gopnik explained it to me.

Esther, along with most other 4- and 5-year-olds tested, bested not just me but most of 88 California undergraduates who took the “and” test. We educated grown-ups failed because our prior biases dictated that we play the game by the more common and efficient “or” rule.

“Or” rules apply far more often in actual life, when a thing’s essence seldom depends on another object’s presence. An arrow’s utility may depend on a bow, but its identity as an arrow does not. Since the “or” rule is more likely correct and simpler to use, I grabbed it and clung.

Esther, however, quickly ditched the “or” rule and hit upon the far less likely “and” rule. Such low-probability hypotheses often fail. But children, like adventurous scientists in a lab, will try these wild ideas anyway, because even if they fail, they often produce interesting results.

Esther and her twin brother, Benny (who played another version of the game), generated low-probability hypotheses as fast as I could breathe. “Maybe if you turn it over and put it on the other end!” “Let’s put all three on!” They were hypothesis machines. Their mother, Wendy Wolfson (who is a science writer), told me they’re like this all the time. “It’s like living with a pair of especially inquisitive otters.”

Alas, Dr. Gopnik said, this trait peaks around 4 or 5. After that, we gradually take less interest in seeing what happens and more in getting it right.

Yet this playlike spirit of speculation and exploration does stay with us, both as individuals and as a species. Studies suggest that free, self-directed play in safe environments enhances resilience, creativity, flexibility, social understanding, emotional and cognitive control, and resistance to stress, depression and anxiety. And we continue to explore as adults, even if not so freely. That’s how we got to the Internet, the moon, and Dr. Gopnik’s lab.

Finally, in the long game of evolution, Dr. Gopnik and some of her fellow scientists hypothesize that humans’ extended period of imaginative play, along with the traits it develops, has helped select for the big brain and rich neural networks that characterize Homo sapiens. This may strike you either as a low-probability or a high-probability hypothesis. But it certainly seems worth playing with.

Conservative Koch Brothers Turning Focus to Newspapers (N.Y.Times)

Published: April 20, 2013

Three years ago, Charles and David Koch, the billionaire industrialists and supporters of libertarian causes, held a seminar of like-minded, wealthy political donors at the St. Regis Resort in Aspen, Colo. They laid out a three-pronged, 10-year strategy to shift the country toward a smaller government with less regulation and taxes.

Kevork Djansezian/Getty Images. The Los Angeles Times is the fourth-largest paper in the country.

The first two pieces of the strategy — educating grass-roots activists and influencing politics — were not surprising, given the money they have given to policy institutes and political action groups. But the third one was: media.

Other than financing a few fringe libertarian publications, the Kochs have mostly avoided media investments. Now, Koch Industries, the sprawling private company of whichCharles G. Koch serves as chairman and chief executive, is exploring a bid to buy the Tribune Company’s eight regional newspapers, including The Los Angeles Times, The Chicago Tribune, The Baltimore Sun, The Orlando Sentinel and The Hartford Courant.

By early May, the Tribune Company is expected to send financial data to serious suitors in what will be among the largest sales of newspapers by circulation in the country. Koch Industries is among those interested, said several people with direct knowledge of the sale who spoke on the condition they not be named. Tribune emerged from bankruptcy on Dec. 31 and has hired JPMorgan Chase and Evercore Partners to sell its print properties.

The papers, valued at roughly $623 million, would be a financially diminutive deal for Koch Industries, the energy and manufacturing conglomerate based in Wichita, Kan., with annual revenue of about $115 billion.

Politically, however, the papers could serve as a broader platform for the Kochs’ laissez-faire ideas. The Los Angeles Times is the fourth-largest paper in the country, and The Tribune is No. 9, and others are in several battleground states, including two of the largest newspapers in Florida, The Orlando Sentinel and The Sun Sentinel in Fort Lauderdale. A deal could include Hoy, the second-largest Spanish-language daily newspaper, which speaks to the pivotal Hispanic demographic.

One person who attended the Aspen seminar who spoke on the condition of anonymity described the strategy as follows: “It was never ‘How do we destroy the other side?’ ”

“It was ‘How do we make sure our voice is being heard?’ ”

Guests at the Aspen seminar included Philip F. Anschutz, the Republican oil mogul who owns the companies that publish The Washington Examiner, The Oklahoman and The Weekly Standard, and the hedge fund executive Paul E. Singer, who sits on the board of the political magazine Commentary. Attendees were asked not to discuss details about the seminar with the press.

A person who has attended other Koch Industries seminars, which have taken place since 2003, says Charles and David Koch have never said they want to take over newspapers or other large media outlets, but they often say “they see the conservative voice as not being well represented.” The Kochs plan to host another conference at the end of the month, in Palm Springs, Calif.

At this early stage, the thinking inside the Tribune Company, the people close to the deal said, is that Koch Industries could prove the most appealing buyer. Others interested, including a group of wealthy Los Angeles residents led by the billionaire Eli Broad and Ronald W. Burkle, both prominent Democratic donors, and Rupert Murdoch’s News Corporation, would prefer to buy only The Los Angeles Times.

The Tribune Company has signaled it prefers to sell all eight papers and their back-office operations as a bundle. (Tribune, a $7 billion media company that also owns 23 television stations, could also decide to keep the papers if they do not attract a high enough offer.)

Koch Industries is one of the largest sponsors of libertarian causes — including the financing of policy groups like the Cato Institute in Washington and the formation of Americans for Prosperity, the political action group that helped galvanize Tea Party organizations and their causes. The company has said it has no direct link to the Tea Party.

This month a Koch representative contacted Eddy W. Hartenstein, publisher and chief executive of The Los Angeles Times, to discuss a bid, according to a person briefed on the conversation who spoke on the condition of anonymity because the conversation was private. Mr. Hartenstein declined to comment.

Koch Industries recently brought on Angela Redding, a consultant based in Salt Lake City, to analyze the media environment and assess opportunities. Ms. Redding, who previously worked at the Charles G. Koch Charitable Foundation, did not respond to requests for comment.

“As an entrepreneurial company with 60,000 employees around the world, we are constantly exploring profitable opportunities in many industries and sectors. So, it is natural that our name would come up in connection with this rumor,” Melissa Cohlmia, a spokeswoman for Koch Companies Public Sector, said in a statement last month.

“We respect the independence of the journalistic institutions referenced in the news stories,” Ms. Cohlmia continued. “But it is our longstanding policy not to comment on deals or rumors of deals we may or may not be exploring.”

One person who has previously advised Koch Industries said the Tribune Company papers were considered an investment opportunity, and were viewed as entirely separate from Charles and David Kochs’ lifelong mission to shrink the size of government.

At least in politically liberal Los Angeles, a conservative paper could be tricky. David H. Koch, who lives in New York and serves as executive vice president of Koch Industries, has said he supports gay marriage and could align with many residents on some social issues, Reed Galen, a Republican consultant in Orange County, Calif., said.

Koch Industries’ main competitor for The Los Angeles Times is a group of mostly Democratic local residents. In the 2012 political cycle, Mr. Broad gave $477,800, either directly or through his foundation, to Democratic candidates and causes, according to the Center for Responsive Politics. Mr. Burkle has long championed labor unions. President Bill Clinton served as an adviser to Mr. Burkle’s money management firm, Yucaipa Companies, which in 2012 gave $107,500 to Democrats and related causes. The group also includes Austin Beutner, a Democratic candidate for mayor of Los Angeles, and an investment banker who co-founded Evercore Partners.

“This will be a bipartisan group,” Mr. Beutner said. “It’s not about ideology, it’s about a civic interest.” (The Los Angeles consortium is expected to also include Andrew Cherng, founder of the Panda Express Chinese restaurant chain and a Republican.)

“It’s a frightening scenario when a free press is actually a bought and paid-for press and it can happen on both sides,” said Ellen Miller, executive director of the Sunlight Foundation, a nonpartisan watchdog group.

Last month, shortly after L.A. Weekly first reported on Koch Industries’ interest in the Tribune papers, the liberal Web site Daily Kos and Courage Campaign, a Los Angeles-based liberal advocacy group, collected thousands of signatures protesting such a deal. Conservatives, meanwhile, welcomed the idea of a handful of prominent papers spreading the ideas of economic “freedom” from taxes and regulation that the Kochs have championed.

Seton Motley, president of Less Government, an organization devoted to shrinking the role of the government, said the 2012 presidential election reinforced the view that conservatives needed a broader media presence.

“A running joke among conservatives as we watched the G.O.P. establishment spend $500 million on ineffectual TV ads is ‘Why don’t you just buy NBC?’ ” Mr. Motley said. “It’s good the Kochs are talking about fighting fire with a little fire.”

Koch Industries has for years felt the mainstream media unfairly covered the company and its founding family because of its political beliefs. KochFacts.com, a Web site run by the company, disputes perceived press inaccuracies. The site, which asserts liberal bias in the news media, has published private e-mail conversations between company press officers and journalists, including the Politico reporter Kenneth P. Vogel and editors at The New Yorker in response to an article about the Kochs by Jane Mayer.

“So far, they haven’t seemed to be particularly enthusiastic about the role of the free press,” Ms. Mayer said in an e-mail, “but hopefully, if they become newspaper publishers, they’ll embrace it with a bit more enthusiasm.”

A Democratic political operative who spoke on the condition of anonymity, said he admired how over decades the brothers have assembled a complex political infrastructure that supports their agenda. A media company seems like a logical next step.

This person said, “If they get some bad press that Darth Vader is buying Tribune, they don’t care.”

Hidrelétricas podem afetar sistema hidrológico do Pantanal (Fapesp)

Projeto para construção de mais 87 pequenas centrais hidrelétricas na bacia do Alto Paraguai pode afetar conectividade da área de planalto com a de planície do bioma pantaneiro e dificultar fluxo migratório de peixes e outras espécies aquáticas, alertam pesquisadores (Walfrido Tomas)

23/04/2013

Por Elton Alisson

Agência FAPESP – O projeto de construção de mais 87 Pequenas Centrais Hidrelétricas (PCHs) na Bacia do Alto Paraguai, em discussão atualmente, pode afetar a conectividade do planalto – onde nasce o Rio Paraguai e seus afluentes – e a planície inundada do Pantanal – por onde as águas desses rios escoam –, dificultando o fluxo migratório de peixes e outras espécies aquáticas e semiaquáticas pelo sistema hidrológico.

O alerta foi feito por pesquisadores durante o terceiro evento do Ciclo de Conferências 2013 do BIOTA Educação, que teve como tema o Pantanal. O evento foi realizado pelo programa BIOTA-FAPESP no dia 18 de abril, na sede da FAPESP.

De acordo com José Sabino, professor da Universidade Anhanguera-Uniderp, o impacto das PCHs já existentes na região da Bacia do Alto Paraguai não são tão grandes porque, em geral, baseiam-se em uma tecnologia denominada “a fio d’água” – que dispensa a necessidade de manter grandes reservatórios de água.

A somatória das cerca de 30 PCHs existentes com as 87 planejadas, no entanto, pode impactar a hidrologia e a conectividade das águas do planalto e da planície da Bacia do Alto Paraguai e dificultar processos migratórios de espécies de peixes do Pantanal, alertou o especialista.

“A criação dessas PCHs pode causar a quebra de conectividade hidrológica de populações e de processos migratórios reprodutivos, como a piracema, de algumas espécies de peixes”, disse Sabino.

Durante a piracema, o período de procriação que antecede as chuvas do verão, algumas espécies de peixes, como o curimbatá (Prochilodus lineatus) e o dourado (Salminus brasiliensis), sobem os rios até as nascentes para desovar.

Se o acesso às cabeceiras dos rios for interrompido por algum obstáculo, como uma PCH, a piracema pode ser dificultada. “A construção de mais PCHs na região do Pantanal pode ter uma influência sistêmica sobre o canal porque, além de mudar o funcionamento hidrológico, também deve alterar a força da carga de nutrientes carregada pelas águas das nascentes dos rios no planalto que entram na planície pantaneira”, disse Walfrido Moraes Tomas, pesquisador do Centro de Pesquisa Agropecuária do Pantanal (CPAP) da Empresa Brasileira de Pesquisa Agropecuária (Embrapa), no Mato Grosso do Sul, palestrante na conferência na FAPESP.

“Isso também poderá ter impactos nos hábitats de espécies aquáticas ou semiaquáticas”, reiterou Tomas. De acordo com o pesquisador, o Pantanal é uma das áreas úmidas mais ricas em espécies do mundo, distribuídas de forma abundante, mas não homogênea, pela planície pantaneira.

Alguns dos últimos levantamentos de espécies apontaram que o bioma possui 269 espécies de peixes, 44 de anfíbios, 127 de répteis, 582 de aves e 152 de mamíferos.

São necessários, no entanto, mais inventários de espécies para preencher lacunas críticas de conhecimento sobre outros grupos, como o dos invertebrados – sobre os quais ainda não há levantamento sobre o número de espécies –, além de crustáceos, moluscos e lepidópteros (ordem de insetos que inclui as borboletas), que ainda são pouco conhecidos.

“Uma iniciativa que vai nos dar uma grande contribuição nesse sentido será o programa Biota Mato Grosso do Sul, que começou ser implementado há três anos”, disse Tomas.

Inspirado no BIOTA-FAPESP, o programa Biota Mato Grosso do Sul pretende consolidar a infraestrutura de coleções e acervos em museus, herbários, jardins botânicos, zoológicos e bancos de germoplasma do Mato Grosso do Sul para preencher lacunas de conhecimento, taxonômicas e geográficas, sobre a diversidade biológica no estado.

Para atingir esse objetivo, pesquisadores pretendem informatizar os acervos e coleções científicas e estabelecer uma rede de informação em biodiversidade entre todas as instituições envolvidas com a pesquisa e conservação de biodiversidade do Mato Grosso do Sul.

“Começamos agora a fazer os primeiros inventários de espécies de regiões- chave do estado e estamos preparando um volume especial da revista Biota Neotropica sobre a biodiversidade de Mato Grosso do Sul, que será um passo fundamental para verificarmos as informações disponíveis sobre a biota do Pantanal e direcionar nossas ações”, disse Tomas à Agência FAPESP.

“Diferentemente do Estado de São Paulo, que tem coleções gigantescas, Mato Grosso do Sul não dispõe de grandes coleções para fazermos mapeamentos de diversidade. Por isso, precisaremos ir a campo para fazer os inventários”, explicou.

Espécies ameaçadas

Segundo Tomas, das espécies de aves ameaçadas, vulneráveis ou em perigo de extinção no Brasil, por exemplo, 188 podem ser encontradas no Pantanal. No entanto, diminuiu muito nos últimos anos a ocorrência de caça de espécies como onça-pintada, onça-parda, ariranha, arara-azul – ave símbolo do Pantanal – e jacaré.

E não há indícios de que a principal atividade econômica da região – a pecuária, que possibilitou a ocupação humana do bioma em um primeiro momento em razão de o ambiente ser uma savana inundada com pastagem renovada todo ano – tenha causado impactos na biota pantaneira.

“Pelo que sabemos até agora, nenhuma espécie da fauna do Pantanal foi levada a risco de extinção por causa da pecuária”, afirmou Tomas. Já a pesca – a segunda atividade econômica mais intensiva no Pantanal – pode ter impactos sobre algumas espécies de peixes.

Isso porque a atividade está focalizada em 20 das 270 espécies de peixes do bioma pantaneiro, em razão do tamanho, sabor da carne e pela própria cultura regional.

Entre elas, estão o dourado, o curimbatá, a piraputanga (Brycon hilarii), o pacu (Piaractus mesopotamicus) e a cachara (Pseudoplatystoma reticulatum) – um peixe arisco encontrado em rios como Prata e Olho D’água, que pode chegar a medir 1,20 metro e pesar 40 quilos.

“Há indícios de que, pelo fato de a pesca no Pantanal ser direcionada a algumas espécies, a atividade possa reduzir algumas populações de peixes”, disse Sabino.

Além de Sabino e Tomas, o professor Arnildo Pott, da Universidade Federal de Mato Grosso do Sul (UFMS), de Campo Grande, também proferiu palestra, sobre a origem, evolução e diversidade da vegetação do Bioma Pantanal.

Estratégias de conservação

Os pesquisadores também chamaram a atenção para o fato de que, atualmente, apenas cerca de 5% do Pantanal está protegido por unidades de conservação. E que muitas das espécies de animais da região, como a onça- pintada, a ariranha e a arara-azul, por exemplo, não são protegidas efetivamente, porque ficam fora dessas unidades de conservação.

“A conservação de espécies ameaçadas no Pantanal requer estratégias mais amplas do que apenas a implantação ou gestão das unidades de conservação”, destacou Tomas. “São necessárias políticas de gestão de bacias hidrográficas e de remuneração por serviços ecossistêmicos para assegurar a conservação de espécies ameaçadas.”

Organizado pelo Programa BIOTA-FAPESP, o Ciclo de Conferências 2013 tem o objetivo de contribuir para o aperfeiçoamento do ensino de ciência. A quarta etapa será no dia 16 de maio, quando o tema será “Bioma Cerrado”. Seguem-se conferências sobre os biomas Caatinga (20 de junho), Mata Atlântica (22 de agosto), Amazônia (19 de setembro), Ambientes Marinhos e Costeiros (24 de outubro) e Biodiversidade em Ambientes Antrópicos – Urbanos e Rurais (21 de novembro).

Earth’s Current Warmth Not Seen in the Last 1,400 Years or More, Says Study (Science Daily)

Apr. 21, 2013 — Fueled by industrial greenhouse gas emissions, Earth’s climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years, according to new regional temperature reconstructions covering all seven continents. This period of humanmade global warming, which continues today, reversed a natural cooling trend that lasted several hundred years, according to results published in the journalNature Geoscience by more than 80 scientists from 24 nations analyzing climate data from tree rings, pollen, cave formations, ice cores, lake and ocean sediments, and historical records from around the world.

“This paper tells us what we already knew, except in a better, more comprehensive fashion,” said study co-author Edward Cook, a tree-ring scientist at Lamont-Doherty Earth Observatory who led the Asia reconstruction.

The study also found that Europe’s 2003 heat wave and drought, which killed an estimated 70,000 people, happened during Europe’s hottest summer of the last 2,000 years. “Summer temperatures were intense that year and accompanied by a lack of rain and very dry soil conditions over much of Europe,” said study co-author Jason Smerdon, a climate scientist at Lamont-Doherty and one of the lead contributors to the Europe reconstruction. Though summer 2003 set a record for Europe, global warming was only one of the factors that contributed to the temperature conditions that summer, he said.

The study is the latest to show that the Medieval Warm Period, from about 950 to 1250, may not have been global, and may not have happened at the same time in places that did grow warmer. While parts of Europe and North America were fairly warm between 950 and 1250, South America stayed relatively cold, the study says. Some people have argued that the natural warming that occurred during the medieval ages is happening today, and that humans are not responsible for modern day global warming. Scientists are nearly unanimous in their disagreement “If we went into another Medieval Warm Period again that extra warmth would be added on top of warming from greenhouse gases,” said Cook.

Temperatures varied less between continents in the same hemisphere than between hemispheres. “Distinctive periods, such as the Medieval Warm Period or the Little Ice Age stand out, but do not show a globally uniform pattern,” said co-author Heinz Wanner, a scientist at the University of Bern. By 1500, temperatures dropped below the long-term average everywhere, though colder temperatures emerged several decades earlier in the Arctic, Europe and Asia.

The most consistent trend across all regions in the last 2,000 years was a long-term cooling, likely caused by a rise in volcanic activity, decrease in solar irradiance, changes in land-surface vegetation, and slow variations in Earth’s orbit. With the exception of Antarctica, cooling tapered off at the end of the 19th century, with the onset of industrialization. Cooler 30-year periods between 830 and 1910 were particularly pronounced during weak solar activity and strong tropical volcanic eruptions. Both phenomena often occurred simultaneously and led to a drop in the average temperature during five distinct 30- to 90-year intervals between 1251 and 1820. Warming in the 20th century was on average twice as large in the northern continents as it was in the Southern Hemisphere. During the past 2000 years, some regions experienced warmer 30-year intervals than during the late 20th century. For example, in Europe the years between 21 and 80 AD were likely warmer than the period 1971-2000.

How the hyperkinetic media is breeding a new generation of terrorists.

BY SCOTT ATRAN | APRIL 22, 2013

“Americans refuse to be terrorized,” declared President Barack Obama in the aftermath of the Boston Marathon bombings. “Ultimately, that’s what we’ll remember from this week.” Believe that, and I’ve got a bridge to sell you in Brooklyn.

The Boston bombings have provoked the most intense display of law enforcement and media coverage since the 9/11 attacks. Greater Boston was in full lockdown: “a ghost town,” “a city in terror,” “a war zone,” screamed the headlines. Public transit was stopped, a no-fly zone proclaimed, people told to stay indoors, schools and universities closed, and hundreds of FBI agents pulled from other pressing investigations to focus exclusively on the case — along with thousands upon thousands of other federal, state, and city agents equipped with heavy weapons and armored vehicles. It all came close to martial law, with all the tools of the security state mobilized to track down a pair of young immigrants with low-tech explosives and small arms who failed to reconcile their problems of identity and became suspected amateur terrorists.

Not that the events weren’t shocking and brutal. But this law enforcement and media response, of course, is part of the overall U.S. reaction to terrorism since 9/11, when perhaps never in history have so few, armed with so few means, caused so much fear in so many. Indeed, as with the anarchists a century ago, last week’s response is precisely the outsized reaction that sponsors of terrorism have always counted on in order to terrorize.

Nothing compares to the grief of parents whose child has been murdered like 8-year-old Martin Richard, except perhaps the collective grief of many parents, as for the 20 children killed in last December’s school massacre in Newtown, Conn. Yet, despite the fact that the probability of a child, or anyone else in the United States, being killed by a terrorist bomb is vastly smaller than being killed by an unregistered handgun — or even by an unregulated fertilizer plant — U.S. politicians and the public seem likely to continue to support uncritically the extravagant measures associated with an irrational policy of “zero tolerance” for terrorism, as opposed to much-more-than-zero tolerance for nearly all other threats of violence. Given the millions of dollars already spent on the Boston bombing investigation and the trillions that the national response to terrorism has cost in little more than a decade, the public deserves a more reasoned response. We can never, ever be absolutely safe, no matter how much treasure we spend or how many civil liberties we sacrifice.

While there is always the chance that investigators will find foreign connections and broader plots beyond the doings of the two men suspected in the Boston bombing, our knowledge about terrorism suggests that what we already know about the April 15 bombing does not justify the disproportionate and overwrought response, including the “global security alert” U.S. authorities issued through Interpol for 190 countries. Even if the suspected Boston bombers prove to be part of a larger network of jihadi wannabes, as were the 2005 London subway suicide bombers, or had planned more operations before dying in a blaze of glory, as did the 2004 Madrid train bombers, these would-be knights under the prophet’s banner could never alone wreak the havoc that our reaction to them does.

The brothers Tsarnaev, the suspected Boston bombers, have been described by neighbors, friends, and relatives as fairly normal young men — regular Cambridge kinds. They left the Chechen conflict years ago and immigrated to the United States as asylum seekers under the U.S. government’s refugee resettlement program. Tamerlan, the oldest, was married with a 3-year-old daughter. A former Golden Gloves heavyweight boxer who once thought of competing for the United States, he had been increasingly drawn to radical Islam in the last few years. In a photo essay about his fondness for boxing, he worried, “I don’t have a single American friend; I don’t understand them.” He complained, “There are no values anymore,” forswearing drinking because “God said no alcohol.” Tamerlan’s YouTube page posts videos of radical Islamic clerics from Chechnya and elsewhere haranguing the West as bombs explode in the background. In 2011, the FBI interviewed Tamerlan at Russia’s request about connections to Chechen extremists, but the investigation found “no derogatory information.” Although Russian forces withdrew from Chechnya in 2009, violence has persisted in neighboring Dagestan, where Tamerlan visited his father last year and perhaps linked up with jihadi instigators who motivated him to act. Like the father of 9/11 pilot bomber Mohamed Atta, Tamerlan’s father claims his boy was framed and murdered. In his last reported phone communication, on Thursday, just hours before the police shootout began, he called his mother.

The younger brother, Dzhokhar, a sophomore at the University of Massachusetts in Dartmouth, played intramural soccer. On the day after the bombing he went to the dorms, worked out at the gym, and that night went to a party attended by some of his soccer buddies. Known to his friends as Jahar, he entered the university on a scholarship but lately had been failing his classes. He hung out with other students, had an easy relationship with the other young men and women, hardly ever talked politics, and was never pegged as an Islamist activist or sympathizer or even as particularly religious. Whereas relatives, friends, and teachers consistently describe Jahar as “always smiling,” “with a heart of gold,” acquaintances say Tamerlan never smiled and was aggressive. One cousin said he warned Jahar about being susceptible to the negative influence of the older brother he loved. In the last few months, Jahar’s tweets began turning darker: “i won’t run i’ll just gun you all out #thugliving,” “Do I look like that much of a softy … little do these dogs know they’re barking at a lion,” “I killed Abe Lincoln during my two hour nap #intensedream.” But declaring this wayward killer — and a naturalized citizen, at that — an “enemy combatant” borders on Orwellian.

Under sponsorship by the Defense Department, my multidisciplinary, multinational research team has been conducting field studies and analyses of the mental and social processes involved in radicalization at home and abroad. Our findings indicate that terrorist plotters against Western civilian populations tend not to be parts of sophisticated, foreign-based command-and-control organizations. Rather, they belong to loose, homegrown networks of family and friends who die not just for a cause, but for each other. Jihadists pretty much span the population’s normal distribution: There are very few psychopaths and sociopaths, few brilliant thinkers and strategists. Jihadi wannabes today are mostly emerging adults in transitional stages of their lives — students, immigrants, in search of jobs or companions — who are especially prone to movements that promise a meaningful cause, camaraderie, adventure, and glory. Most have a secular education, becoming “born again” into the jihadi cause in their late teens or 20s. The path to radicalization can take years, months, or just days, depending on personal vulnerabilities and the influence of others. Occasionally there is a hookup with a relative, or a friend of a friend, who has some overseas connection to someone who can get them a bit of training and motivation to pack a bag of explosives or pull a trigger, but the Internet and social media are usually sufficient for radicalization and even operational preparation.

The result is not a hierarchic, centrally commanded terrorist movement but a decentralized, self-organizing, and constantly evolving complex of social networks based on contingent adaptations to changing events. These are no real “cells,” but only clusters of mostly young men who motivate one another within “brotherhoods” of real and fictive kin. Often, in fact, there is an older brother figure, a dominant personality who mobilizes others in the group. But rarely is there an overriding authority or father figure. (Notably, for these transitional youth, there’s often an absence of a real father).

Some of the most successful plots, such as the Madrid and London bombings, are so anarchic, fluid, and improbable that they succeeded in evading detection despite the fact that intelligence and law enforcement agencies had been following some of the actors for some time. Three key elements characterize the “organized anarchy” that typifies modern violent Islamic activism: Ultimate goals are vague and superficial (often no deeper than revenge against perceived injustice against Muslims around the world); modes of action are decided pragmatically on the basis of trial and error or based on the residue of learning from accidents of past experience; and those who join are not recruited but are locally linked self-seekers — often from the same family, neighborhood, or Internet chat room — whose connection to global jihad is more virtual than material. Al Qaeda and associates do not so much recruit as attract disaffected individuals who have already decided to embark on the path to violent extremism with the help of family, friends, or a few fellow travelers.

Like the young men who carried out the Madrid and London attacks, most homegrown jihadi plotters first hook up with the broad protest sentiment against “the global attack on Islam” before moving into a narrower parallel universe. They cut ties with former companions who they believe are too timid to act and cement bonds with those who are willing to strike. They emerge from their cocoon with strong commitment to strike and die if necessary, but without any clear contingency planning for what might happen after the initial attack.

For the first time in history, a massive, media-driven political awakening has been occurring — spurred by the advent of the Internet, social media, and cable television — that can, on the one hand, motivate universal respect for human rights while, on the other, enable, say, Muslims from Borneo to sacrifice themselves for Palestine, Afghanistan, or Chechnya (despite almost no contact or shared history for the last 50,000 years or so). When perceived global injustice resonates with frustrated personal aspirations, moral outrage gives universal meaning and provides the push to radicalization and violent action.

But the popular notion of a “clash of civilizations” between Islam and the West is woefully misleading. Violent extremism represents not the resurgence of traditional cultures, but their collapse, as young people unmoored from millennial traditions flail about in search of a social identity that gives personal significance. This is the dark side of globalization.

Take Faisal Shahzad, the would-be bomber of Times Square in 2010, or Maj. Nidal Hasan, who killed 13 fellow soldiers at Fort Hood in 2009. Both were apparently inspired by the online rhetoric of Anwar al-Awlaki, a former preacher at a Northern Virginia mosque who was killed by a U.S. drone in Yemen in 2011. Although many commentators leapt to the conclusion that Awlaki and his ilk deviously brainwashed and recruited Shahzad and Hassan, in fact they sought out the popular Internet preacher because they were already radicalized to the point of wanting further guidance to act. As Defense Department terrorism consultant Marc Sageman notes: “Just like you saw Major Hasan send 21 emails to al-Awlaki, who sends him two back, you have people seeking these guys and asking them for advice.” More than 80 percent of plots in both Europe and the United States were concocted from the bottom up by mostly young people just hooking up with one another.

Especially for young men, mortal combat with a “band of brothers” in the service of a great cause is both the ultimate adventure and a road to esteem in the hearts of their peers. For many disaffected souls today, jihad is a heroic cause — a promise that anyone from anywhere can make a mark against the most powerful country in the history of the world. But because would-be jihadists best thrive and act in small groups and among networks of family and friends — not in large movements or armies — their threat can only match their ambitions if fueled way beyond actual strength. And publicity is the oxygen that fires modern terrorism.

It is not by arraying “every element of our national power” against would-be jihadists and those who inspire them that violent extremism will be stopped, as Obama once declared. Although wide-ranging intelligence, good police work, and security preparedness (including by the military and law enforcement) is required to track and thwart the expansion of al Qaeda affiliates into the Arabian Peninsula, Syria (and perhaps Jordan), North Africa, and East Africa, this is insufficient. As 2012 U.S. presidential candidate Mitt Romney quipped, “We can’t kill our way out of this mess.” In the United States, there are many pockets of displaced immigrant and refugee young people with even more than the usual struggles of personal development. Young Somalis seem to be having particular difficulty, and a small few are moving to the path of violent jihad. This is a good time to think about how we relate to them, though there are probably more easy mistakes than easy solutions. But political attempts to relate these problems to the very different issue of illegal immigration only adds to the scaremongering.

We need to pay attention to what makes these young men want to die to kill, by listening to their families and friends, trying to engage them on the Internet, and seeing whom they idolize, how they organize, what bonds them, and what drives them. U.S. power won’t stop the self-seeking, and preaching “moderate” Islam (or moderate anything) is hardly likely to sway young men in search of significance and glory. And even if every airplane passenger were to be scanned naked or every American city locked down, it would not stop young men from joining the jihad or concocting new ways of killing civilians.

Terrorists are directly responsible for violent acts, but only indirectly for the reaction that follows. Objectively, terrorist acts on even a 9/11 scale could never seriously harm American society; only our reaction can. By amplifying and connecting relatively sporadic terrorist acts into a generalized “war” or “assault on freedom,” the somewhat marginal phenomenon of terrorism has become a primary preoccupation of the U.S. government and American people. In this sense, Osama bin Laden has been victorious beyond his wildest dreams — not because of anything he has done, but because of how we have reacted to the episodic successes he inspires.

There are several ways to react to the political hype and media amplification of terrorism. Doing nothing and allowing this frenzied media environment to continue will only encourage future attacks; meanwhile, reporting that rushes to judgment and complements law enforcement’s denial of Miranda rights will only erode confidence in the integrity and fairness of the American press and U.S. government institutions. Legal regulation of media, as in many other countries, may not be compatible with a free society and if tried would certainly provoke persistent opposition and deep outrage. For example, previous attempts by the British government to ban interviews with terrorists and their supporters backfired. As the 6th U.S. Circuit Court of Appeals noted in 2002, “Democracies die behind closed doors.” Even noncoercive guidelines are likely to incite widespread resistance. As former New York Times Executive Editor A.M. Rosenthal put it: “The last thing in the world I want is guidelines. I don’t want guidelines from the government … or anyone else.”

But voluntary self-restraint by the media, which is less intrusive and supported by many, is not only possible but manageable. (Venerable journalist Edward R. Murrow, informed by President Franklin D. Roosevelt on the specifics of the Pearl Harbor attack, declined the scoop and didn’t file his report until the administration could formulate a reasoned response.) Of course, “gentle censorship,” like the initially successful attempts by George W. Bush’s administration to prevent airing of bin Laden messages or talks with terrorists, can seriously hamper the flow of knowledge necessary for understanding what makes terrorists tick and how to thwart them.

The First Amendment enables the news media to watchdog the republic and help prevent government excesses and abuses so that a well-informed public can monitor and decide where government policy should go. Yet the media is increasingly less a public service devoted to this task than a competitive business that believes it best succeeds through sensation, which violence privileges. For example, the typical television news story has declined from an average of several minutes in the 1950s and 1960s to today’s repeated sound bites — often no more than a few seconds — that sensationalize the spectacular. And despite the fact that one of the suspected Boston bombers is now dead and the other in custody, it can be argued that their terrorism succeeded through the spectacular theater of last week’s events, capturing our attention and stoking our deepest fears.

We can break this real, if unplanned, alliance between terrorism and the media through better reporting for the social good, which may prove to be the best business strategy of all. When we practice restraint and show the resilience of people carrying on with their lives even in the face of atrocities like that in Boston, then terrorism fails.

Mathematical Models Out-Perform Doctors in Predicting Cancer Patients’ Responses to Treatment (Science Daily)

Apr. 19, 2013 — Mathematical prediction models are better than doctors at predicting the outcomes and responses of lung cancer patients to treatment, according to new research presented today (Saturday) at the 2nd Forum of the European Society for Radiotherapy and Oncology (ESTRO).

These differences apply even after the doctor has seen the patient, which can provide extra information, and knows what the treatment plan and radiation dose will be.

“The number of treatment options available for lung cancer patients are increasing, as well as the amount of information available to the individual patient. It is evident that this will complicate the task of the doctor in the future,” said the presenter, Dr Cary Oberije, a postdoctoral researcher at the MAASTRO Clinic, Maastricht University Medical Center, Maastricht, The Netherlands. “If models based on patient, tumour and treatment characteristics already out-perform the doctors, then it is unethical to make treatment decisions based solely on the doctors’ opinions. We believe models should be implemented in clinical practice to guide decisions.”

Dr Oberije and her colleagues in The Netherlands used mathematical prediction models that had already been tested and published. The models use information from previous patients to create a statistical formula that can be used to predict the probability of outcome and responses to treatment using radiotherapy with or without chemotherapy for future patients.

Having obtained predictions from the mathematical models, the researchers asked experienced radiation oncologists to predict the likelihood of lung cancer patients surviving for two years, or suffering from shortness of breath (dyspnea) and difficulty swallowing (dysphagia) at two points in time:

1) after they had seen the patient for the first time, and

2) after the treatment plan was made. At the first time point, the doctors predicted two-year survival for 121 patients, dyspnea for 139 and dysphagia for 146 patients.

At the second time point, predictions were only available for 35, 39 and 41 patients respectively.

For all three predictions and at both time points, the mathematical models substantially outperformed the doctors’ predictions, with the doctors’ predictions being little better than those expected by chance.

The researchers plotted the results on a special graph [1] on which the area below the plotted line is used for measuring the accuracy of predictions; 1 represents a perfect prediction, while 0.5 represents predictions that were right in 50% of cases, i.e. the same as chance. They found that the model predictions at the first time point were 0.71 for two-year survival, 0.76 for dyspnea and 0.72 for dysphagia. In contrast, the doctors’ predictions were 0.56, 0.59 and 0.52 respectively.

The models had a better positive predictive value (PPV) — a measure of the proportion of patients who were correctly assessed as being at risk of dying within two years or suffering from dyspnea and dysphagia — than the doctors. The negative predictive value (NPV) — a measure of the proportion of patients that would not die within two years or suffer from dyspnea and dysphagia — was comparable between the models and the doctors.

“This indicates that the models were better at identifying high risk patients that have a very low chance of surviving or a very high chance of developing severe dyspnea or dysphagia,” said Dr Oberije.

The researchers say that it is important that further research is carried out into how prediction models can be integrated into standard clinical care. In addition, further improvement of the models by incorporating all the latest advances in areas such as genetics, imaging and other factors, is important. This will make it possible to tailor treatment to the individual patient’s biological make-up and tumour type

“In our opinion, individualised treatment can only succeed if prediction models are used in clinical practice. We have shown that current models already outperform doctors. Therefore, this study can be used as a strong argument in favour of using prediction models and changing current clinical practice,” said Dr Oberije.

“Correct prediction of outcomes is important for several reasons,” she continued. “First, it offers the possibility to discuss treatment options with patients. If survival chances are very low, some patients might opt for a less aggressive treatment with fewer side-effects and better quality of life. Second, it could be used to assess which patients are eligible for a specific clinical trial. Third, correct predictions make it possible to improve and optimise the treatment. Currently, treatment guidelines are applied to the whole lung cancer population, but we know that some patients are cured while others are not and some patients suffer from severe side-effects while others don’t. We know that there are many factors that play a role in the prognosis of patients and prediction models can combine them all.”

At present, prediction models are not used as widely as they could be by doctors. Dr Oberije says there are a number of reasons: some models lack clinical credibility; others have not yet been tested; the models need to be available and easy to use by doctors; and many doctors still think that seeing a patient gives them information that cannot be captured in a model. “Our study shows that it is very unlikely that a doctor can outperform a model,” she concluded.

President of ESTRO, Professor Vincenzo Valentini, a radiation oncologist at the Policlinico Universitario A. Gemelli, Rome, Italy, commented: “The booming growth of biological, imaging and clinical information will challenge the decision capacity of every oncologist. The understanding of the knowledge management sciences is becoming a priority for radiation oncologists in order for them to tailor their choices to cure and care for individual patients.”

The Tangle of the Sexes (N.Y.Times)

GRAY MATTER

By BOBBI CAROTHERS and HARRY REIS

Published: April 20, 2013

MEN and women are so different they might as well be from separate planets, so says the theory of the sexes famously explicated in John Gray’s 1992 best seller, “Men Are From Mars, Women Are From Venus.”

Jonny Negron

Indeed, sex differences are a perennially popular topic in behavioral science; since 2000, scientific journals have published more than 30,000 articles on them.

That men and women differ in certain respects is unassailable. Unfortunately, the continuing belief in “categorical differences” — men are aggressive, women are caring — reinforces traditional stereotypes by treating certain behaviors as immutable. And, it turns out, this belief is based on a scientifically indefensible model of human behavior.

As the psychologist Cordelia Fine explains in her book “Delusions of Gender,” the influence of one kind of categorical thinking, neurosexism — justifying differential treatment by citing differences in neural anatomy or function — spills over to educational and employment disparities, family relations and arguments about same-sex institutions.

Consider a marital spat in which she accuses him of being emotionally withdrawn while he indicts her for being demanding. In a gender-categorical world, the argument can quickly devolve to “You’re acting like a typical (man/woman)!” Asking a partner to change, in this binary world, is expecting him or her to go against the natural tendency of his or her category — a very tall order.

The alternative, a dimensional perspective, ascribes behavior to individuals, as one of their various personal qualities. It is much easier to imagine how change might take place.

But what of all those published studies, many of which claim to find differences between the sexes? In our research, published recently in The Journal of Personality and Social Psychology, we shed an empirical light on this question by using a method called taxometric analysis.

This method asks whether data from two groups are likely to be taxonic — a classification that distinguishes one group from another in a nonarbitrary, fundamental manner, called a “taxon” — or whether they are more likely to be dimensional, with individuals’ scores dispersed along a single continuum.

The existence of a taxon implies a fundamental distinction, akin to the difference between species. As the clinical psychologist Paul Meehl famously put it, “There are gophers, there are chipmunks, but there are no gophmunks.”

A dimensional model, in contrast, indicates that men and women come from the same general pool, differing relatively, trait by trait, much as any two individuals from the same group might differ.

We applied such techniques to the data from 13 studies, conducted earlier by other researchers. In each, significant differences had been found. We then looked more closely at these differences to ask whether they were more likely to be of degree (a dimension) or kind (a taxon).

The studies looked at diverse attributes, including sexual attitudes and behavior, desired mate characteristics, interest in and ease of learning science, and intimacy, empathy, social support and caregiving in relationships.

Across analyses spanning 122 attributes from more than 13,000 individuals, one conclusion stood out: instead of dividing into two groups, men and women overlapped considerably on attributes like the frequency of science-related activities, interest in casual sex, or the allure of a potential mate’s virginity.

Even stereotypical traits, like assertiveness or valuing close friendships, fell along a continuum. In other words, we found little or no evidence of categorical distinctions based on sex.

To some, this is no surprise; the psychologist Janet Hyde has argued repeatedly that men and women are far more similar than different. Yet to many others, the idea that men and women are fundamentally different beings persists. The Mars/Venus binary aside, it is all too easy to reify observed behavioral differences by associating them with the categories of the people doing the behaving, be it their sex, race or occupation.

It is important to keep in mind what we did not study. We looked only at psychological characteristics, qualities often associated with the behavior of women and men. We did not look at abilities or skills, and we did not directly observe behavior.

Just to be safe, we repeated our analyses on several dimensions where we did expect categorical differences: physical size, athletic ability and sex-stereotyped hobbies like playing video games and scrapbooking. On these we did find evidence for categories based on sex.

The Mars/Venus view describes a world that does not exist, at least here on earth. Our work shows that sex does not define qualitatively distinct categories of psychological characteristics. We need to look at individuals as individuals.

How Science Can Predict Where You Stand on Keystone XL (Mother Jones)

Want to make sense of the feud between pipeline activists and “hippie-punching” moderates? Talk to the researchers.

On February 17, more than 40,000 climate change activists—many of them quite young—rallied in Washington, DC, to oppose the Keystone XL pipeline, which will transport dirty tar sands oil from Canada across the heartland. The scornful response from media centrists was predictable. Joe Nocera of the New York Times, for one, quickly went on the attack. In a column titled “How Not to Fix Climate Change,” he wrote that the strategy of activists “who have made the Keystone pipeline their line in the sand is utterly boneheaded.”

Nocera, who accepts the science of climate change, made a string of familiar arguments: The tar sands will be exploited anyway, the total climate contribution of the oil that would be transported by Keystone XL is minimal, and so on. Perhaps inspired by Nocera-style thinking, a group of 17 Democratic senators would later cast a symbolic vote in favor of the pipeline, signaling that opposing industrial projects is not the brand of environmentalism that they, at least, have in mind.

The Keystone activists, not surprisingly, were livid. Not only did they challenge Nocera’s facts, they utterly rejected his claims as to the efficacy of their strategy: Opponents of the pipeline have often argued that it is vital to push the limits of the possible—in particular, to put unrelenting pressure on President Obama to lead on climate change. Van Jones, the onetime Obama clean-energy adviser and a close supporter of 350.org founder and Keystone protest leader Bill McKibben, has put it like this: “I think activism works…The lesbian, gay, bisexual, and transgender movement kept pushing on the question of marriage equality, and the president came out for marriage equality, which then had a positive effect on public opinion and helped that movement win at the ballot box and in a number of states, within months.”

This article is about the emotionally charged dispute between climate activists and environmental moderates, despite their common acceptance of the science of climate change. Why does this sort of rift exist on so many issues dividing the center from the left? And what can we actually say about which side is, you know, right?

Does Joe Nocera really have a sound basis for calling the pipeline opponents’ strategy boneheaded—or is that just his gut feeling as a centrist? Does Van Jones have any basis for claiming that activism works—or is it just his gut feeling as someone favorably disposed towards activism?

This line of inquiry should prove duly humbling to both activists and moderates—and help to unite them.

It’s high time we considered the science on these questions. There is, after all, considerable scholarly work on whether activists, by pushing the boundaries of what seems acceptable, create the conditions for progress or, instead, bring about backlashes that can complicate the jobs of sympathetic policymakers.

There’s also data that may shed light on why these rifts between “moderates” and “activists” are more the rule than the exception—across the ideological spectrum. “I can’t really think of any movement where there isn’t some internal dissent about goals and tactics,” says Carleton College political scientist Devashree Gupta, who studies social movements. The recurrence of this pattern on issues from civil rights to gun control to abortion suggests that there is something here that’s well worth understanding, preferably before the next rhetorical bloodbath around Keystone.

A chief benefit of this line of inquiry: It should prove duly humbling to activists and moderates alike—and thus might help to unite them.

FROM THE OUTSET, I think we can agree on one fundamental point: Over the past several years, driven by the failure of cap and trade and a worsening climate crisis, America’s environmental movement has become considerably more activist in nature—some might even say “radical.” Exhibit A is the successful attempt by 350.org inspirer-in-chief McKibben (who has written extensively about climate for Mother Jones) to create a grassroots protest movement rather than simply to work within the corridors of power.

“What Bill is doing is actually quite impressive—he’s the first one to create a social movement around climate change, and he’s done it by creating a common enemy, the oil industry, and a salient target, which is Keystone,” says Andrew Hoffman, a professor at the University of Michigan who studies environmental politics.

There’s really little doubt that the “dark greens” are on the ascendant.

One crucial aspect of this shift is a growing reluctance by environmentalists to work hand in hand with big polluters. The latter was a central feature of the US Climate Action Partnership, the industry-environmental collaboration that led an unsuccessful cap-and-trade push a few years back. Nowadays, the environmental movement is moving toward a more oppositional relationship with industry, as evidenced by its attempts to block a major industrial project (Keystone) and to get universities and cities to drop their investments in fossil fuel companies (another of McKibben’s goals).

The rival environmental factions are sometimes described as “dark greens” (the purists who want to force radical change) and “bright greens” (those who seek compromise and accept tradeoffs). There’s really little doubt that dark greens are on the ascendant. “He’s pulling the flank out,” Hoffman says of McKibben. “I do think he has a valuable role in creating a space where others can create a more moderate role.”

Then along come the moderates, unleashing flurries of “hippie punching” under the guise of being more rational than the activists they are criticizing.

It’s also fair to say that McKibben—the charismatic journalist-turned-organizer—lies a good way to the political left. Its centrist biases notwithstanding, a recent paper by American University communications professor Matthew Nisbet does capture McKibben’s “romantic” ideology: Like most people, he’s unhappy about environmental degradation, but he also seems opposed, in a significant sense, to the economic growth engine that drives it. He believes in living smaller, in going back to nature, in consuming less—not a position many politicians would be willing to espouse. (Indeed, President Obama’s comments about climate change often contain an explicit rejection of the idea that environmental and economic progress are mutually exclusive.)

So environmentalists are moving left and becoming more activist in response to political gridlock and scary planetary rumblings. Then along come the moderates, unleashing flurries of what Grist‘s David Roberts calls “hippie punching” under the guise of being more rational and reasoned than those they are criticizing. For example, Nisbet writes: “McKibben’s line-in-the-sand opposition to the Keystone XL oil pipeline, his skepticism of technology, and his romantic vision of a future consisting of small-scale, agrarian communities reflects his own values and priorities, rather than a pragmatic set of choices designed to effectively and realistically address the problem of climate change.”

You can see how an activist might find this just a tad irritating. For what is Nisbet’s statement if not a reflection of his own values and priorities? Words like “pragmatic” and “realistic” give away the game.

Carbon bubble will plunge the world into another financial crisis – report (The Guardian)

Trillions of dollars at risk as stock markets inflate value of fossil fuels that may have to remain buried forever, experts warn

The world could be heading for a major economic crisis as stock marketsinflate an investment bubble in fossil fuels to the tune of trillions of dollars, according to leading economists.

“The financial crisis has shown what happens when risks accumulate unnoticed,” said Lord (Nicholas) Stern, a professor at the London School of Economics. He said the risk was “very big indeed” and that almost all investors and regulators were failing to address it.

The so-called “carbon bubble” is the result of an over-valuation of oil,coal and gas reserves held by fossil fuel companies. According to a report published on Friday, at least two-thirds of these reserves will have to remain underground if the world is to meet existing internationally agreed targets to avoid the threshold for “dangerous” climate changeIf the agreements hold, these reserves will be in effect unburnable and so worthless – leading to massive market losses. But the stock markets are betting on countries’ inaction on climate change.

The stark report is by Stern and the thinktank Carbon Tracker. Their warning is supported by organisations including HSBC, Citi, Standard and Poor’s and the International Energy Agency. The Bank of England has also recognised that a collapse in the value of oil, gas and coal assets as nations tackle global warming is a potential systemic risk to the economy, with London being particularly at risk owing to its huge listings of coal.

Stern said that far from reducing efforts to develop fossil fuels, the top 200 companies spent $674bn (£441bn) in 2012 to find and exploit even more new resources, a sum equivalent to 1% of global GDP, which could end up as “stranded” or valueless assets. Stern’s landmark 2006 reporton the economic impact of climate change – commissioned by the then chancellor, Gordon Brown – concluded that spending 1% of GDP would pay for a transition to a clean and sustainable economy.

The world’s governments have agreed to restrict the global temperature rise to 2C, beyond which the impacts become severe and unpredictable. But Stern said the investors clearly did not believe action to curb climate change was going to be taken. “They can’t believe that and also believe that the markets are sensibly valued now.”

“They only believe environmental regulation when they see it,” said James Leaton, from Carbon Tracker and a former PwC consultant. He said short-termism in financial markets was the other major reason for the carbon bubble. “Analysts say you should ride the train until just before it goes off the cliff. Each thinks they are smart enough to get off in time, but not everyone can get out of the door at the same time. That is why you get bubbles and crashes.”

Paul Spedding, an oil and gas analyst at HSBC, said: “The scale of ‘listed’ unburnable carbon revealed in this report is astonishing. This report makes it clear that ‘business as usual’ is not a viable option for the fossil fuel industry in the long term. [The market] is assuming it will get early warning, but my worry is that things often happen suddenly in the oil and gas sector.”

HSBC warned that 40-60% of the market capitalisation of oil and gas companies was at risk from the carbon bubble, with the top 200 fossil fuel companies alone having a current value of $4tn, along with $1.5tn debt.

Lord McFall, who chaired the Commons Treasury select committee for a decade, said: “Despite its devastating scale, the banking crisis was at its heart an avoidable crisis: the threat of significant carbon writedown has the unmistakable characteristics of the same endemic problems.”

The report calculates that the world’s currently indicated fossil fuel reserves equate to 2,860bn tonnes of carbon dioxide, but that just 31% could be burned for an 80% chance of keeping below a 2C temperature rise. For a 50% chance of 2C or less, just 38% could be burned.

Carbon capture and storage technology, which buries emissions underground, can play a role in the future, but even an optimistic scenario which sees 3,800 commercial projects worldwide would allow only an extra 4% of fossil fuel reserves to be burned. There are currently no commercial projects up and running. The normally conservativeInternational Energy Agency has also concluded that a major part of fossil fuel reserves is unburnable.

Citi bank warned investors in Australia’s vast coal industry that little could be done to avoid the future loss of value in the face of action on climate change. “If the unburnable carbon scenario does occur, it is difficult to see how the value of fossil fuel reserves can be maintained, so we see few options for risk mitigation.”

Ratings agencies have expressed concerns, with Standard and Poor’s concluding that the risk could lead to the downgrading of the credit ratings of oil companies within a few years.

Steven Oman, senior vice-president at Moody’s, said: “It behoves us as investors and as a society to know the true cost of something so that intelligent and constructive policy and investment decisions can be made. Too often the true costs are treated as unquantifiable or even ignored.”

Jens Peers, who manages €4bn (£3bn) for Mirova, part of €300bn asset managers Natixis, said: “It is shocking to see the report’s numbers, as they are worse than people realise. The risk is massive, but a lot of asset managers think they have a lot of time. I think they are wrong.” He said a key moment will come in 2015, the date when the world’s governments have pledged to strike a global deal to limit carbon emissions. But he said that fund managers need to move now. If they wait till 2015, “it will be too late for them to take action.”

Pension funds are also concerned. “Every pension fund manager needs to ask themselves have we incorporated climate change and carbon risk into our investment strategy? If the answer is no, they need to start to now,” said Howard Pearce, head of pension fund management at the Environment Agency, which holds £2bn in assets.

Stern and Leaton both point to China as evidence that carbon cuts are likely to be delivered. China’s leaders have said its coal use will peak in the next five years, said Leaton, but this has not been priced in. “I don’t know why the market does not believe China,” he said. “When it says it is going to do something, it usually does.” He said the US and Australia were banking on selling coal to China but that this “doesn’t add up”.

Jeremy Grantham, a billionaire fund manager who oversees $106bn of assets, said his company was on the verge of pulling out of all coal and unconventional fossil fuels, such as oil from tar sands. “The probability of them running into trouble is too high for me to take that risk as an investor.” He said: “If we mean to burn all the coal and any appreciable percentage of the tar sands, or other unconventional oil and gas then we’re cooked. [There are] terrible consequences that we will lay at the door of our grandchildren.”

Politicians Found to Be More Risk-Tolerant Than the General Population (Science Daily)

Apr. 16, 2013 — According to a recent study, the popularly elected members of the German Bundestag are substantially more risk-tolerant than the broader population of Germany. Researchers in the Cluster of Excellence “Languages of Emotion” at Freie Universität Berlin and at DIW Berlin (German Institute for Economic Research) conducted a survey of Bundestag representatives and analyzed data on the general population from the German Socio-Economic Panel Study (SOEP). Results show that risk tolerance is even higher among Bundestag representatives than among self-employed people, who are themselves more risk-tolerant than salaried employees or civil servants. This was true for all areas of risk that were surveyed in the study: automobile driving, financial investments, sports and leisure activities, career, and health. The authors interpret this finding as positive.

The full results of the study were published in German in the SOEPpapers series of the German Institute for Economic Research (DIW Berlin).

The authors of the study, Moritz Hess (University of Mannheim), Prof. Dr. Christian von Scheve (Freie Universität Berlin and DIW Berlin), Prof. Dr. Jürgen Schupp (DIW Berlin and Freie Universität Berlin), and Prof. Dr. Gert G. Wagner (DIW Berlin and Technische Universität Berlin) view the above-average risk tolerance found among Bundestag representatives as positive. According to sociologist and lead author of the study Moritz Hess: “Otherwise, important societal decisions often wouldn’t be made due to the almost incalculable risks involved. This would lead to stagnation and social standstill.” The authors do not interpret the higher risk-tolerance found among politicians as a threat to democracy. “The results show a successful and sensible division of labor among citizens, voters, and politicians,” says economist Gert G. Wagner. Democratic structures and parliamentary processes, he argues, act as a brake on the individual risk propensity of elected representatives and politicians.

For their study, the research team distributed written questionnaires to all 620 members of the 17th German Bundestag in late 2011. Twenty-eight percent of Bundestag members responded. Comparisons with the statistical characteristics of all current Bundestag representatives showed that the respondents comprise a representative sample of Bundestag members. SOEP data were used to obtain a figure for the risk tolerance of the general population for comparison with the figures for Bundestag members.

The questions posed to Bundestag members were formulated analogously to the questions in the standard SOEP questionnaire. Politicians were asked to rate their own risk tolerance on a scale from zero (= not at all risk-tolerant) to ten (= very risk-tolerant). They rated both their general risk tolerance as well as their specific risk tolerance in the areas of driving, making financial investments, sports and leisure activities, career, health, and trust towards strangers. They also rated their risk tolerance in regard to political decisions. No questions on party affiliation were asked in order to exclude the possibility that results could be used for partisan political purposes.

Índios isolados, trabalhadores em fuga: um encontro amazônico (Yahoo Notícias)

Por Ana Aranha | Reportagem 3 por 4 – 18.abr.2013

Os seis trabalhadores da construção civil estavam perdidos em meio à floresta amazônica, no norte de Rondônia. Algumas horas antes, eles tinham corrido mato a dentro para fugir do caos que tomara o canteiro de obras da usina hidrelétrica de Jirau, onde a Polícia Militar reprimia o movimento grevista, em 2011. Depois de andar cerca de seis quilômetros, o grupo tentava encontrar o caminho de volta à obra, ou a estrada, ou qualquer sinal de urbanidade. Sem sucesso.

Ao invés disso, foram encontrados.

Sem perceber que estavam sendo cercados, os trabalhadores uniformizados se viram rodeados por oito índios nus. Eles tinham o rosto e corpo pintados, flechas em punho e “murmuravam” palavras em uma língua que os trabalhadores não conheciam. Mas logo interpretaram o sentido: estavam rendidos.

Índios isolados no Acre, fotografados pela Funai em 2008

Hoje, excepcionalmente, esse espaço não será dedicado a um retrato, mas a um encontro. Encontro que pode servir de pista para compor o retrato dos povos indígenas que habitam o nosso país e os quais temos tanta dificuldade de entender.

Assustados, os trabalhadores da usina se comportaram como prisioneiros dos índios. Seguiram seus passos e pararam quando eles sinalizaram. O coração disparava a cada vez que os índios se reuniam em círculo. Observaram a construção de uma espécie de churrasqueira com gravetos, onde um porco do mato foi assado. Disfarçando o mal estar, comeram cada pedaço de carne que lhes foi oferecido. À noite, um dos trabalhadores foi repreendido pelos colegas por espiar os seios da índia mais nova, a regra era olhar para o chão.

A madrugada avançou, alguns índios deitaram e adormeceram. Os trabalhadores ficaram alertas. Pela manhã, caminharam até chegar a um local onde se ouvia um barulho familiar. Os índios sinalizaram em direção ao som, disseram algumas frases que ninguém entendeu e foram embora. Os trabalhadores correram na direção indicada até que, exaustos, chegaram à rodovia federal BR 364.

Esse relato foi registrado pela historiadora Ivaneide Bandeira Cardozo, da ONG indigenista Kanindé, que entrevistou um dos trabalhadores na presença de um funcionário da Funai (Fundação Nacional do Índio). Ela acredita que os homens e mulheres descritos sejam parte de um grupo que a entidade e a Funai tentam rastrear há anos. “Pela descrição, parecem ser Kawahiba isolados”.

“Isolados” são os índios que não têm contato com a nossa sociedade, ou porque nunca cruzaram com um não-índio (casos cada vez mais raros) ou porque recusam o contato.

Na região que foi alagada pela usina de Jirau, havia rastros de um grupo isolado e nômade. A empresa repassou dinheiro para que a Funai mapeasse esses rastros. Depois de identificados, eles deveriam ganhar uma área de proteção. Mas o investimento não foi suficiente para encontrar ou proteger os índios.

Ao contrário, foram eles que encontraram e salvaram os funcionários da usina. “É difícil entender o que passou na cabeça dos índios quando viram os trabalhadores perdidos”, reflete Ivaneide. “Por que decidiram ajudar? Nunca vamos saber”.

O encontro ocorrido em 2011 é o reflexo oposto do desencontro que se deu na Câmara dos Deputados essa semana. Na terça dia 16, em uma cena inédita, os deputados federais correram pelo plenário como uma manada assustada. Fugiam de homens seminus, pintados de urucum e que balançavam seus chocalhos para protestar contra a mudança da lei que define como as terras indígenas são demarcadas.

Se o comportamento dos índios isolados e dos deputados deixa alguma pista, é que continuamos longe de entender os povos que habitam a nossa terra.

Quando retornaram à usina, os trabalhadores contaram sobre o encontro, mas o supervisor deu risada, chamando-os de mentirosos. Como se fosse impossível haver índios nas proximidades da obra, cravada no meio da floresta amazônica.

Para Ivaneide, a precisão dos detalhes é a maior evidência da veracidade da história. “Os trabalhadores eram de outros estados, uma pessoa sem convivência com indígenas não poderia saber tanto. Ele descreveu a pintura no peito, os traços no rosto dos homens, diferente das mulheres, a pena do gavião real, como tratavam a ponta das flechas. Até os detalhes de como montaram o moquém, que é onde assam a carne”. Segundo ela, o relato bate com hábitos comuns a etnias que vivem ou viveram na região, algumas consideradas extintas.

Existem 82 pistas de grupos indígenas isolados no Brasil, é a maior concentração de povos isolados do mundo. Em março desse ano, os funcionários da Funai fizeram uma carta aberta com um “pedido de socorro”. Nela, escrevem que não há equipe para proteger esses grupos, cujos territórios estão sendo invadidos pelas grandes obras, madeireiros e traficantes.

Como lidar com índios isolados é um dos temas mais complexos dentro da política indigenista. Talvez a pequena mensagem deixada pelo grupo que resgatou os trabalhadores e pelos que invadiram o congresso seja justamente sobre os nossos limites. Os índios tem um modo diferente de ser, nem sempre seremos capazes de entende-los. Talvez esses encontros sejam os momentos para refletir sobre os impactos das nossas escolhas. E fazer um esforço para, a partir dessa nova realidade, respeitar as escolhas deles.

Female Anthropologists Harassed (The Scientist)

[Why the photo of Maasai people? -RT]

A new survey finds a high incidence of sexual harassment and rape among women doing anthropological field work.

More than 20 percent of female bioanthropologists who took part in a new survey are victims of “physical sexual harassment or unwanted sexual contact” in the course of their scientific research, primarily at the hand of superior professional colleagues, even their own mentors.

After talking to a friend that had been raped by a colleague, anthropologist Kathryn Clancy of the University of Illinois, Urbana-Champaign decided to look into the matter further.  “It was like a slap in the face to learn that this was happening to my friends,” Clancy told ScienceInsider.

She began posting anonymous stories of sexual harassment, shared with her by her female colleagues, on the Scientific American blog Context and Variation. The stories began to draw comments of other researchers’ harassment stories. “This is definitely not limited to just my discipline,” Clancy told ScienceInsider—nor is it limited to females, she found.

To get a better handle on the frequency with which such harassment occurs, Clancy and colleagues conducted a (still ongoing) online survey, asking scientists to report on their field-work experiences. Preliminary results, presented Saturday (April 13) at the American Association of Physical Anthropologists (AAPA) annual meeting in Knoxville, Tennessee, indicated that about 30 percent of both men and women reported the occurrence of verbal abuse “regularly” or “frequently” at field sites. And 21 percent of women reported having experienced physical sexual harassment or unwanted sexual contact; one out of 23 men also reported such abuse.

Notably, fewer than 20 percent of the reported cases of harassment involved the local community; rather, most of the abuse came from other researchers, primarily those further along in their careers. But why are such experiences so rarely reported?

“Quitting a field site, not completing and publishing research, and/or loss of letters of recommendation can have potent consequences for academic careers,” collaborator Katie Hinde of Harvard University told ScienceInsider. “Taken together, these factors result in a particularly vulnerable population of victims and witnesses powerless to intervene. As a discipline, we need to recognize and remedy that an appreciable non-zero number of our junior colleagues, particularly women, are having to endure harassment and a hostile work environment in order to be scientists.”

Brazil accused of not protecting isolated indigenous group (AP)

By Associated Press, Published: April 18

SAO PAULO — Brazil’s government has failed to comply with a court order to protect the Awa indigenous people in the Amazon jungles, a British-based Indian rights group said Thursday.

Survival International said in a statement that authorities have ignored a federal judge’s deadline “to evict all invaders from the heartland of Earth’s most threatened tribe by the end of March.” It said the deadline passed and not a single illegal logger or settler has been evicted.

On March 12, 2012, judge Jirair Aram Meguerian ordered that all the loggers and settlers should be removed within 12 months.

The organization said the Awa tribe “is at extreme risk of extinction.”

It added that Funai, Brazil’s indigenous affairs agency was “still waiting for support from the Justice Ministry, the federal police and central government to evict the invaders.”

Funai’s press office said it had no immediate comment. Calls to the Justice Ministry and federal police went unanswered.

Survival International said that more than 30 percent of Awa territory has been deforested and that loggers are “rapidly closing in on their communities and have already been marking trees for deforestation.

It quotes an Awa Indian called Haikaramoka’a, as saying: “The loggers are ruining our forest. They have built roads. We are scared; they could go after the uncontacted Indians. We are scared because the loggers could kill us, and the uncontacted Indians.”

About 100 of the 450 Awa remain uncontacted and are at particular risk of diseases brought in by the outsiders. Survival International said.

Zonas costeiras em debate (Ministério do Meio Ambiente)

Leila Swerts aponta problemas das áreas litorâneasMartim Garcia/MMA. Leila Swerts aponta problemas das áreas litorâneas

Ações do Programa Nacional de Gerenciamento Costeiro são apresentadas em seminário realizado nesta quinta-feira na Câmara dos Deputados

LUCAS TOLENTINO

A proteção dos ecossistemas marinhos e das áreas costeiras do país está em pauta no Congresso Nacional. A Câmara dos Deputados realiza, nesta quinta-feira (11), o seminário “25 Anos da Constituição Federal e a Proteção dos Ecossistemas Costeiros e Marinhos”. O encontrou tem o objetivo de promover o diálogo entre os diversos órgãos governamentais e a sociedade civil sobre os impactos e alterações que a zona litorânea do país tem sofrido, além de propor alternativas e soluções para o problema.

Muitas das ações relativas ao tema são definidas no âmbito do Grupo de Integração do Programa Nacional de Gerenciamento Costeiro (GI-Gerco), formado por representantes do governo federal, da academia, do Ministério Público Federal (MPF) e do terceiro setor. Segundo a coordenadora da Gerência Costeira da Secretaria de Extrativismo e Desenvolvimento Rural Sustentável do MMA, Leila Swerts, a participação de segmentos diferenciados garante a efetividade do processo.

Os riscos à zona costeira foram mencionados pela coordenadora durante o debate realizado na manhã desta quinta-feira. De acordo com a coordenadora, 24% da população do país vivem nessas regiões e os problemas vão desde o crescimento desordenado aos efeitos causados pelas mudanças climáticas. “Está havendo um adensamento dessas áreas e, por isso, estamos trabalhando pelo aumento de pautas relacionadas à gestão costeiras dentro do colegiado”, explicou Leila, que integra o comitê executivo do GI-Gerco.

MONITORAMENTO

Entre os projetos do MMA para a preservação da zona costeira está o Sistema de Modelagem Costeira (SMC), desenvolvido em parceria com a Espanha. Criado originalmente pelo país europeu, a iniciativa consiste em uma base de dados que permite o monitoramento das linhas de praias. O objetivo é fazer uma plataforma nos mesmos moldes em território nacional para qualificar o planejamento e a tomada de decisões destinadas ao litoral brasileiro.

O diretor do Programa Marinho da Conservação Internacional (CI), Guilherme Dutra, destacou a importância do uso da tecnologia nesse processo. “É necessário medir e estudar o que está ocorrendo com os oceanos e precisamos ter acesso a essas informações, ou seja, de pactos pela governança, pelo planejamento e pela sustentabilidade”, defendeu Dutra, que representou a sociedade civil no Painel Governamental do evento.

Ocean’s Future Not So Bleak? Resilience Found in Shelled Plants Exposed to Ocean Acidification (Science Daily)

Apr. 12, 2013 — Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems. But a group led by a UC Santa Barbara professor has found a point of resilience in a microscopic shelled plant with a massive environmental impact, which suggests the future of ocean life may not be so bleak.

As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. “As pH declines, there is this concern that marine species that have shells may start dissolving or may have more difficulty making calcium carbonate, the chalky substance that they use to build shells,” said Debora Iglesias-Rodriguez, a professor in UCSB’s Department of Ecology, Evolution and Marine Biology.

Iglesias-Rodriguez and postdoctoral researcher Bethan Jones, who is now at Rutgers University, led a large-scale study on the effects of ocean acidification on these tiny plants that can only be seen under the microscope. Their research, funded by the European Project on Ocean Acidification, is published in the journal PLoS ONE and breaks with traditional notions about the vitality of calcifiers, or creatures that make shells, in future ocean conditions.

“The story years ago was that ocean acidification was going to be bad, really bad for calcifiers,” said Iglesias-Rodriguez, whose team discovered that one species of the tiny single celled marine coccolithophore, Emiliania huxleyi, actually had bigger shells in high carbon dioxide seawater conditions. While the team acknowledges that calcification tends to decline with acidification, “we now know that there are variable responses in sea corals, in sea urchins, in all shelled organisms that we find in the sea.”

These E. huxleyi are a large army of ocean-regulating shell producers that create oxygen as they process carbon by photosynthesis and fortify the ocean food chain. As one of Earth’s main vaults for environmentally harmful carbon emissions, their survival affects organisms inside and outside the marine system. However, as increasing levels of atmospheric carbon dioxide causes seawater to slide down the pH scale toward acidic levels, this environment could become less hospitable.

The UCSB study incorporated an approach known as shotgun proteomics to uncover how E. huxleyi‘s biochemistry could change in future high carbon dioxide conditions, which were set at four times the current levels for the study. This approach casts a wider investigative net that looks at all changes and influences in the environment as opposed to looking at individual processes like photosynthesis.

Shotgun proteomics examines the type, abundance, and alterations in proteins to understand how a cell’s machinery is conditioned by ocean acidification. “There is no perfect approach,” said Iglesias-Rodriguez. “They all have their caveats, but we think that this is a way of extracting a lot of information from this system.”

To mirror natural ocean conditions, the team used over half a ton of seawater to grow the E. huxleyi and bubbled in carbon dioxide to recreate both present day and high future carbon levels. It took more than six months for the team to grow enough plants to accumulate and analyze sufficient proteins.

The team found that E. huxleyi cells exposed to higher carbon dioxide conditions were larger and contained more shell than those grown in current conditions. However, they also found that these larger cells grow slower than those under current carbon dioxide conditions. Aside from slower growth, the higher carbon dioxide levels did not seem to affect the cells even at the biochemical level, as measured by the shotgun proteomic approach.

“The E. huxleyi increased the amount of calcite they had because they kept calcifying but slowed down division rates,” said Iglesias-Rodriguez. “You get fewer cells but they look as healthy as those under current ocean conditions, so the shells are not simply dissolving away.”

The team stresses that while representatives of this species seem to have biochemical mechanisms to tolerate even very high levels of carbon dioxide, slower growth could become problematic. If other species grow faster, E. huxleyi could be outnumbered in some areas.

“The cells in this experiment seemed to tolerate future ocean conditions,” said Jones. “However, what will happen to this species in the future is still an open question. Perhaps the grow-slow outcome may end up being their downfall as other species could simply outgrow and replace them.”

Mathematics Provides a Shortcut to Timely, Cost-Effective Interventions for HIV (Science Daily)

Apr. 15, 2013 — Mathematical estimates of treatment outcomes can cut costs and provide faster delivery of preventative measures.

South Africa is home to the largest HIV epidemic in the world with a total of 5.6 million people living with HIV. Large-scale clinical trials evaluating combination methods of prevention and treatment are often prohibitively expensive and take years to complete. In the absence of such trials, mathematical models can help assess the effectiveness of different HIV intervention combinations, as demonstrated in a new study by Elisa Long and Robert Stavert from Yale University in the US. Their findings appear in the Journal of General Internal Medicine, published by Springer.

Currently 60 percent of individuals in need of treatment for HIV in South Africa do not receive it. The allocation of scant resources to fight the HIV epidemic means each strategy must be measured in terms of cost versus benefit. A number of new clinical trials have presented evidence supporting a range of biomedical interventions that reduce transmission of HIV. These include voluntary male circumcision — now recommended by the World Health Organization and Joint United Nations Programme on HIV/AIDS as a preventive strategy — as well as vaginal microbicides and oral pre-exposure prophylaxis, all of which confer only partial protection against HIV. Long and Stavert show that a combination portfolio of multiple interventions could not only prevent up to two-thirds of future HIV infections, but is also cost-effective in a resource-limited setting such as South Africa.

The authors developed a mathematical model accounting for disease progression, mortality, morbidity and the heterosexual transmission of HIV to help forecast future trends in the disease. Using data specific for South Africa, the authors estimated the health benefits and cost-effectiveness of a “combination approach” using all three of the above methods in tandem with current levels of antiretroviral therapy, screening and counseling.

For each intervention, they calculated the HIV incidence and prevalence over 10 years. At present rates of screening and treatment, the researchers predict that HIV prevalence will decline from 19 percent to 14 percent of the population in the next 10 years. However, they calculate that their combination approach including male circumcision, vaginal microbicides and oral pre-exposure prophylaxis could further reduce HIV prevalence to 10 percent over that time scale — preventing 1.5 million HIV infection over 10 years — even if screening and antiretroviral therapy are kept at current levels. Increasing antiretroviral therapy use and HIV screening frequency in addition could avert more than 2 million HIV infections over 10 years, or 60 percent of the projected total.

The researchers also determined a hierarchy of effectiveness versus cost for these intervention strategies. Where budgets are limited, they suggest money should be allocated first to increasing male circumcision, then to more frequent HIV screening, use of vaginal microbicides and increasing antiretroviral therapy. Additionally, they calculate that omitting pre-exposure prophylaxis from their combination strategy could offer 90 percent of the benefits of treatment for less than 25 percent of the costs.

The authors conclude: “In the absence of multi-intervention randomized clinical or observational trials, a mathematical HIV epidemic model provides useful insights about the aggregate benefit of implementing a portfolio of biomedical, diagnostic and treatment programs. Allocating limited available resources for HIV control in South Africa is a key priority, and our study indicates that a multi-intervention HIV portfolio could avert nearly two-thirds of projected new HIV infections, and is a cost-effective use of resources.”

Photons Run out of Loopholes: Quantum World Really Is in Conflict With Our Everyday Experience (Science Daily)

Apr. 15, 2013 — A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons in which they have closed an important loophole. The researchers have thus provided the most complete experimental proof that the quantum world is in conflict with our everyday experience.

The results of this study appear this week in the journal Nature (Advance Online Publication/AOP).

When we observe an object, we make a number of intuitive assumptions, among them that the unique properties of the object have been determined prior to the observation and that these properties are independent of the state of other, distant objects. In everyday life, these assumptions are fully justified, but things are different at the quantum level. In the past 30 years, a number of experiments have shown that the behaviour of quantum particles — such as atoms, electrons or photons — can be in conflict with our basic intuition. However, these experiments have never delivered definite answers. Each previous experiment has left open the possibility, at least in principle, that the observed particles ‘exploited’ a weakness of the experimental setup.

Quantum physics is an exquisitely precise tool for understanding the world around us at a very fundamental level. At the same time, it is a basis for modern technology: semiconductors (and therefore computers), lasers, MRI scanners, and numerous other devices are based on quantum-physical effects. However, even after more than a century of intensive research, fundamental aspects of quantum theory are not yet fully understood. On a regular basis, laboratories worldwide report results that seem at odds with our everyday intuition but that can be explained within the framework of quantum theory.

On the trail of the quantum entanglement mystery

The physicists in Vienna report not a new effect, but a deep investigation into one of the most fundamental phenomena of quantum physics, known as ‘entanglement.’ The effect of quantum entanglement is amazing: when measuring a quantum object that has an entangled partner, the state of the one particle depends on measurements performed on the partner. Quantum theory describes entanglement as independent of any physical separation between the particles. That is, entanglement should also be observed when the two particles are sufficiently far apart from each other that, even in principle, no information can be exchanged between them (the speed of communication is fundamentally limited by the speed of light). Testing such predictions regarding the correlations between entangled quantum particles is, however, a major experimental challenge.

Towards a definitive answer

The young academics in Anton Zeilinger’s group including Marissa Giustina, Alexandra Mech, Rupert Ursin, Sven Ramelow and Bernhard Wittmann, in an international collaboration with the National Institute of Standards and Technology/NIST (USA), the Physikalisch-Technische Bundesanstalt (Germany), and the Max-Planck-Institute of Quantum Optics (Germany), have now achieved an important step towards delivering definitive experimental evidence that quantum particles can indeed do things that classical physics does not allow them to do. For their experiment, the team built one of the best sources for entangled photon pairs worldwide and employed highly efficient photon detectors designed by experts at NIST. These technological advances together with a suitable measurement protocol enabled the researchers to detect entangled photons with unprecedented efficiency. In a nutshell: “Our photons can no longer duck out of being measured,” says Zeilinger.

This kind of tight monitoring is important as it closes an important loophole. In previous experiments on photons, there has always been the possibility that although the measured photons do violate the laws of classical physics, such non-classical behaviour would not have been observed if all photons involved in the experiment could have been measured. In the new experiment, this loophole is now closed. “Perhaps the greatest weakness of photons as a platform for quantum experiments is their vulnerability to loss — but we have just demonstrated that this weakness need not be prohibitive,” explains Marissa Giustina, lead author of the paper.

Now one last step

Although the new experiment makes photons the first quantum particles for which, in several separate experiments, every possible loophole has been closed, the grand finale is yet to come, namely, a single experiment in which the photons are deprived of all possibilities of displaying their counterintuitive behaviour through means of classical physics. Such an experiment would also be of fundamental significance for an important practical application: ‘quantum cryptography,’ which relies on quantum mechanical principles and is considered to be absolutely secure against eavesdropping. Eavesdropping is still theoretically possible, however, as long as there are loopholes. Only when all of these are closed is a completely secure exchange of messages possible.

An experiment without any loopholes, says Zeilinger, “is a big challenge, which attracts groups worldwide.” These experiments are not limited to photons, but also involve atoms, electrons, and other systems that display quantum mechanical behaviour. The experiment of the Austrian physicists highlights the photons’ potential. Thanks to these latest advances, the photon is running out of places to hide, and quantum physicists are closer than ever to conclusive experimental proof that quantum physics defies our intuition and everyday experience to the degree suggested by research of the past decades.
