Summary: Ground-breaking experiments have been conduced to uncover the links between language and emotions. Researchers were able to demonstrate that the articulation of vowels systematically influences our feelings and vice versa. The authors concluded that it would seem that language users learn that the articulation of ‘i’ sounds is associated with positive feelings and thus make use of corresponding words to describe positive circumstances. The opposite applies to the use of ‘o’ sounds.

A team of researchers headed by the Erfurt-based psychologist Prof. Ralf Rummer and the Cologne-based phoneticist Prof. Martine Grice has carried out some ground-breaking experiments to uncover the links between language and emotions. They were able to demonstrate that the articulation of vowels systematically influences our feelings and vice versa.

The research project looked at the question of whether and to what extent the meaning of words is linked to their sound. The specific focus of the project was on two special cases; the sound of the long ‘i’ vowel and that of the long, closed ‘o’ vowel. Rummer and Grice were particularly interested in finding out whether these vowels tend to occur in words that are positively or negatively charged in terms of emotional impact. For this purpose, they carried out two fundamental experiments, the results of which have now been published in Emotion, the journal of the American Psychological Association.

In the first experiment, the researchers exposed test subjects to film clips designed to put them in a positive or a negative mood and then asked them to make up ten artificial words themselves and to speak these out loud. They found that the artificial words contained significantly more ‘i’s than ‘o’s when the test subjects were in a positive mood. When in a negative mood, however, the test subjects formulated more ‘words’ with ‘o’s.

The second experiment was used to determine whether the different emotional quality of the two vowels can be traced back to the movements of the facial muscles associated with their articulation. Rummer and Grice were inspired by an experimental configuration developed in the 1980s by a team headed by psychologist Fritz Strack. These researchers instructed their test subjects to view cartoons while holding a pen in their mouth in such a way that either the zygomaticus major muscle (which is used when laughing and smiling) or its antagonist, the orbicularis oris muscle, was contracted. In the first case, the test subjects were required to place the pen between their teeth and in the second case between their lips. While their zygomaticus major muscle was contracted, the test subjects found the cartoons significantly more amusing. Instead of this ‘pen-in-mouth test’, the team headed by Rummer and Grice now conducted an experiment in which they required their test subjects to articulate an ‘i’ sound (contraction of the zygomaticus major muscle) or an ‘o’ sound (contraction of the orbicularis oris muscle) every second while viewing cartoons. The test subjects producing the ‘i’ sounds found the same cartoons significantly more amusing than those producing the ‘o’ sounds instead.

In view of this outcome, the authors concluded that it would seem that language users learn that the articulation of ‘i’ sounds is associated with positive feelings and thus make use of corresponding words to describe positive circumstances. The opposite applies to the use of ‘o’ sounds. And thanks to the results of their two experiments, Rummer and Grice now have an explanation for a much-discussed phenomenon. The tendency for ‘i’ sounds to occur in positively charged words (such as ‘like’) and for ‘o’ sounds to occur in negatively charged words (such as ‘alone’) in many languages appears to be linked to the corresponding use of facial muscles in the articulation of vowels on the one hand and the expression of emotion on the other.

People with tinnitus process emotions differently from their peers, researchers report (Science Daily)

Summary:Patients with persistent ringing in the ears — a condition known as tinnitus — process emotions differently in the brain from those with normal hearing, researchers report. Tinnitus afflicts 50 million people in the United States, and causes those with the condition to hear noises that aren’t really there. These phantom sounds are not speech, but rather whooshing noises, train whistles, cricket noises or whines. Their severity often varies day to day.

Patients with persistent ringing in the ears — a condition known as tinnitus — process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research.

Tinnitus afflicts 50 million people in the United States, according to the American Tinnitus Association, and causes those with the condition to hear noises that aren’t really there. These phantom sounds are not speech, but rather whooshing noises, train whistles, cricket noises or whines. Their severity often varies day to day.

University of Illinois speech and hearing science professor Fatima Husain, who led the study, said previous studies showed that tinnitus is associated with increased stress, anxiety, irritability and depression, all of which are affiliated with the brain’s emotional processing systems.

“Obviously, when you hear annoying noises constantly that you can’t control, it may affect your emotional processing systems,” Husain said. “But when I looked at experimental work done on tinnitus and emotional processing, especially brain imaging work, there hadn’t been much research published.”

She decided to use functional magnetic resonance imaging (fMRI) brain scans to better understand how tinnitus affects the brain’s ability to process emotions. These scans show the areas of the brain that are active in response to stimulation, based upon blood flow to those areas.

Three groups of participants were used in the study: people with mild-to-moderate hearing loss and mild tinnitus; people with mild-to-moderate hearing loss without tinnitus; and a control group of age-matched people without hearing loss or tinnitus. Each person was put in an fMRI machine and listened to a standardized set of 30 pleasant, 30 unpleasant and 30 emotionally neutral sounds (for example, a baby laughing, a woman screaming and a water bottle opening). The participants pressed a button to categorize each sound as pleasant, unpleasant or neutral.

The tinnitus and normal-hearing groups responded more quickly to emotion-inducing sounds than to neutral sounds, while patients with hearing loss had a similar response time to each category of sound. Over all, the tinnitus group’s reaction times were slower than the reaction times of those with normal hearing.

Activity in the amygdala, a brain region associated with emotional processing, was lower in the tinnitus and hearing-loss patients than in people with normal hearing. Tinnitus patients also showed more activity than normal-hearing people in two other brain regions associated with emotion, the parahippocampus and the insula. The findings surprised Husain.

“We thought that because people with tinnitus constantly hear a bothersome, unpleasant stimulus, they would have an even higher amount of activity in the amygdala when hearing these sounds, but it was lesser,” she said. “Because they’ve had to adjust to the sound, some plasticity in the brain has occurred. They have had to reduce this amygdala activity and reroute it to other parts of the brain because the amygdala cannot be active all the time due to this annoying sound.”

Because of the sheer number of people who suffer from tinnitus in the United States, a group that includes many combat veterans, Husain hopes her group’s future research will be able to increase tinnitus patients’ quality of life.

“It’s a communication issue and a quality-of-life issue,” she said. “We want to know how we can get better in the clinical realm. Audiologists and clinicians are aware that tinnitus affects emotional aspects, too, and we want to make them aware that these effects are occurring so they can better help their patients.”

For the next generation: Democracy ensures we don’t take it all with us (Science Daily)

Summary: Given the chance to vote, people will leave behind a legacy of resources that ensures the survival of the next generation, a series of experiments by psychologists show. However, when people are left to their own devices, the next generation isn’t so lucky.

Given the chance to vote, people will leave behind a legacy of resources that ensures the survival of the next generation, a series of experiments by Yale and Harvard psychologists show. However, when people are left to their own devices, the next generation isn’t so lucky.

“People want to do the right thing; they just need a little help from their institutions,” said David Rand, assistant professor of psychology at Yale and a co-author of the study appearing June 25 in the journalNature.

The experiments shed light on the psychology underlying issues such as Social Security funding or resource conservation, in which the interests of future generations are at stake.

The study builds upon “public goods” economics experiments that consistently show that people are willing to forego immediate reward if convinced the group as a whole will benefit. But Rand and Harvard colleagues Martin Nowak, Oliver Hauer, and Alexander Peysakhovich wanted to know if people would be willing to sacrifice resources if the benefit accrues not to individuals in a group, but to people not yet born.

In their experiments, they broke subjects into groups of five and gave them 100 units to spend. In one experiment, each individual could take out up to 20 units, but if the group as a whole used more than 50 units, all successor groups would get nothing. If a given group showed restraint, a line-up of successor groups — new generations each consisting of five new people — would be given the same choices.

The good news was that more than two out of three people were willing to take only 10 units — the sustainable “fair share” allotment — for their own use and preserve resources for the next generation. The bad news was that the minority of selfish individuals consistently destroyed the resource for future generations. Even one or two people in the group taking more than their “fair share” was enough to push the group over the 50 unit threshold, exhausting the resource. In 18 experiments in which individuals were free to extract more than 10 units, only four groups left enough resources to support a second generation, and by the fourth generation, all resources were exhausted.

The results changed dramatically when democratic principles were introduced. All five members of the group voted for a number of units to take. The median vote was then taken out for all group members. In this scenario, all groups passed on enough resources to sustain future generations. Even when researchers made the sacrifice more costly — reducing the “sustainable” level of units available to the group to 40 or even 30 — a majority of groups passed resources down through generations.

Problems arose in a third scenario when only three of five members voted on how many units to take. The results of the vote were not binding for the other two subjects. Here sustainability failed, because a selfish person not bound by the vote could over-consume and destroy the resource.

The latter results would be equivalent to Kyoto protocols, a non-binding attempt to get nations to reduce carbon emissions, the authors noted.

“You are wasting your time if voting results are not binding on everyone,” Rand said.

While voting may be potentially challenging for global-level international agreements, it is much more promising for local- or national-level sustainability policies, note the researchers. In a final analysis of real-world data, Rand and colleagues show that democratic countries of the world have made most advances toward sustainability, even when accounting for factors such as wealth, population size, economic output, and inequality.

Researchers treat incarceration as a disease epidemic, discover small changes help (Science Daily)

Date: June 25, 2014

Summary: By treating incarceration as an infectious disease, researchers show that small differences in prison sentences can lead to large differences in incarceration rates. The incarceration rate has nearly quadrupled since the U.S. declared a war on drugs, researchers say. Along with that, racial disparities abound. Incarceration rates for black Americans are more than six times higher than those for white Americans, according to the U.S. Bureau of Justice Statistics.

The incarceration rate has nearly quadrupled since the U.S. declared a war on drugs, researchers say. Along with that, racial disparities abound. Incarceration rates for black Americans are more than six times higher than those for white Americans, according to the U.S. Bureau of Justice Statistics.

To explain these growing racial disparities, researchers at Virginia Tech are using the same modeling techniques used for infectious disease outbreaks to take on the mass incarceration problem.

By treating incarceration as an infectious disease, the scientists demonstrated that small but significant differences in prison sentences can lead to large differences in incarceration rates. The research was published in June in the Journal of the Royal Society Interface.

Incarceration can be “transmitted” to others, the researchers say. For instance, incarceration can increase family members’ emotional and economic stress or expose family and friends to a network of criminals, and these factors can lead to criminal activity.

Alternatively, “official bias” leads police and the courts to pay more attention to the incarcerated person’s family and friends, thereby increasing the probability they will be caught, prosecuted and processed by the criminal justice system, researchers said.

“Regardless of the specific mechanisms involved,” said Kristian Lum, a former statistician at the Virginia Bioinformatics Institute now working for DataPad, “the incarceration of one family member increases the likelihood of other family members and friends being incarcerated.”

Building on this insight, incarceration is treated like a disease in the model and the incarcerated are infectious to their social contacts — their family members and friends most likely affected by their incarceration.

“Criminologists have long recognized that social networks play an important role in criminal behavior, the control of criminal behavior, and the re-entry of prisoners into society,” said James Hawdon, a professor of sociology in the College of Liberal Arts and Human Sciences. “We therefore thought we should test if networks also played a role in the incarceration epidemic. Our model suggests they do.”

Synthesizing publically available data from a variety of sources, the researchers generated a realistic, multi-generational synthetic population with contact networks, sentence lengths, and transmission probabilities.

The researchers’ model is comparable to real-world incarceration rates, reproducing many facets of incarceration in the United States.

Both the model and actual statistics show large discrepancies in incarceration rates between black and white Americans and, subsequently, the likelihood of becoming a repeat offender is high.

Comparisons such as these can be used to validate the assumption that incarceration is infectious.

“Research clearly shows that this epidemic has had devastating effects on individuals, families, and entire communities,” Lum said. “Since our model captures the emergent properties of the incarceration epidemic, we can use it to test policy options designed to reverse it.”

Harsher sentencing may actually result in higher levels of criminality. Examining the role of social influence is an important step in reducing the growing incarceration epidemic.

Pesquisa identifica padrões de entonação do português brasileiro (Fapesp)

Estudo integra projetos internacionais e inclui o idioma falado no Brasil em banco de dados de fala de diferentes línguas românicas (FFLCH-USP)
26/06/2014

Por Diego Freire

Agência FAPESP – Além do vocabulário próprio e de peculiaridades relacionadas aos elementos das frases, o português falado no Brasil tem importantes diferenças em relação ao de Portugal e de outros países lusófonos no ritmo e na entonação da fala.

Foi na melodia da língua falada que se concentraram os estudos da pesquisa “Fraseamento entoacional em português brasileiro”, conduzida com o apoio da FAPESP por Flaviane Romani Fernandes Svartman, do Departamento de Letras Clássicas e Vernáculas da Faculdade de Filosofia, Letras e Ciências Humanas da Universidade de São Paulo (FFLCH-USP).

Frases escritas da mesma forma em todas as variedades do português são faladas de maneiras diferentes em cada lugar. Enquanto um brasileiro lê a sentença “A libanesa maravilhosa rememorava a melodia” pronunciando de forma mais marcante, em termos melódicos, as sílabas tônicas de cada palavra, um português marca melodicamente as sílabas iniciais e finais, dando a impressão de um ritmo mais acelerado.

A sentença faz parte das gravações feitas pelos pesquisadores para os estudos. Por meio de leituras e conversações espontâneas de grupos de pessoas falantes do dialeto paulista, a pesquisa construiu uma base de dados que vai compor o Atlas Interativo da Prosódia do Português, o InAPoP, projeto ao qual a pesquisa de Svartman se vincula, coordenado pela pesquisadora Sónia Frota, da Universidade de Lisboa, com apoio da Fundação para a Ciência e Tecnologia do Ministério da Ciência e do Ensino Superior de Portugal. As gravações permitiram o estudo das estruturas de entonação e do processo de formação de padrões prosódicos de fala.

O trabalho do grupo de Svartman integra também o projeto internacional Intonational Phrasing in Romance, desenvolvido por pesquisadores da Aix Marseille Université, na França, da Euskal Herriko Unibertsitatea, no País Basco, da Universidade de Lisboa, em Portugal, e da Universitat Pompeu Fabra, na Catalunha, e incluiu o português brasileiro na construção de um banco de dados da entonação das diferentes línguas românicas, o Romance Languages Database (RLD).

Trata-se de um extenso banco de dados de fala inicialmente criado para os idiomas catalão, português e espanhol, composto por frases com sujeito, verbo e objeto nesta ordem e padronizadas em número de sílabas e em complexidade sintática e prosódica – permitindo, dessa forma, uma comparação direta entre as línguas e suas variedades. Além de Svartman, colaboram com o RLD a catalã Pilar Prieto, a portuguesa Sónia Frota e o espanhol Gorka Elordieta.

Parte da base de dados do dialeto paulista já está disponível para pesquisadores e interessados em geral no site do InAPoP. Com o auxílio de alunos de iniciação científica e de mestrado da FFLCH, foram realizadas gravações de sentenças interrogativas, exclamativas e focalizadas – aquelas em que há ênfase em alguma parte da frase, como quando se fala “João veio, mas não o Pedro, reforçando a palavra “João” em oposição a “Pedro”.

Uma das gravações foi feita durante uma tarefa de localização e indicação de direções em mapas por mulheres na faixa etária de 20 a 40 anos; outra, durante um relato oral sobre a profissão e experiências marcantes vividas por uma pessoa com mais de 65 anos. As pessoas são separadas por gênero e idade de modo a não permitir variações de fala em um mesmo grupo.

Em seguida, foram feitas descrições e análises do fraseamento entoacional de parte desses dados, comparando-os com outras variedades do português brasileiro e do português europeu. Os resultados foram divulgados na comunicação “Fatores determinantes na atribuição de acentos tonais em sentenças neutras do português”, proferida no Castilho – II Congresso Internacional de Linguística Histórica da USP.

Guiné-Bissau e Europa

Na comparação com outras línguas românicas, a pesquisa observou que no espanhol, no português do norte de Portugal e no português brasileiro há variação melódica entre o sujeito e o predicado, diferente do português europeu padrão – o dialeto lisboeta.

A pesquisa incluiu ainda a variedade falada na Guiné-Bissau como objeto das análises comparativas. A inclusão foi proporcionada pelo contato com intercambistas do país africano, vindos como alunos regulares do curso de Letras da FFLCH-USP por meio de convênio internacional com instituições de ensino superior.

A pesquisa investigou até que ponto as variedades de português se aproximam ou se distanciam quanto a aspectos prosódicos. Tanto nos dados analisados do português brasileiro como nos da Guiné-Bissau há variações melódicas associadas a praticamente cada palavra das sentenças.

No português brasileiro não há variação depois da última sílaba tônica da última palavra que compõe o sujeito em sentenças neutras, enquanto no português da Guiné-Bissau a variação melódica é percebida.

Por exemplo, na sentença “O boliviano mulherengo memorizava uma melodia”, um brasileiro pronuncia de forma mais marcante, melodicamente, as sílabas tônicas do sujeito – o “a” de “boliviano” e o “ren” de “mulherengo” – e um guineense, além disso, também marca a última sílaba da última palavra que compõe esse elemento. Em outras sentenças os falantes do português da Guiné-Bissau podem marcar elementos sintáticos diferentes, como o objeto.

Além da FAPESP, os estudos contaram com o apoio institucional do Laboratório de Apoio à Pesquisa e ao Ensino de Letras (Lapel) da FFLCH-USP na constituição de bases de dados de fala.

The Compelling Conclusion About Capitalism That Piketty Resists (Truthout)

The excesses of capitalism are not simply a question of bad management and a political unwillingness to properly regulate it by imposing the right sort of checks and balances, but symptoms of a fundamentally and irretrievably flawed system that tends toward destruction of human and other life.

The idea of capitalism as an expression of economic freedom that also secures moral and political freedom of thought, or the notion that “free-market” economies are guided by an impartial mechanism of supply and demand – an “invisible hand” to use Adam Smith’s metaphor – are both powerful indoctrinating notions. As such, they bear little resemblance to actual reality. Smith himself never used the word “capitalism,” preferring to call his economics a “system of natural liberty.” In fact, the inner logic of capitalism can be difficult to get hold of simply because there have been different configurations of capitalism throughout history. In its classic form, before the advent of corporations (when there was still an implicit sense of social responsibility, and insatiable greed was considered a vice), capitalism might have appeared less virulent. Additionally, there is reason to believe that capitalism unfolded differently in different countries with distinct political and legal frameworks.

“There is “capitalism” and then there is “really existing capitalism.” What then is ‘really existing capitalism?'”

All of these contingent factors are worthy of consideration in any assessment of capitalism. However, it is also reasonably clear that once we actually look at history, it is difficult not to conclude that pretty muchevery embodiment of capitalism – classical capitalism, oligarchic or corporate capitalism, casino capitalism, entrepreneurial capitalism – presuppose similar elements: private property, ownership of the means of production, notions of unlimited growth, the maximization of profit, using wealth to create wealth. They also all embody a form of instrumental rationality, the kind of rationality concerned with maximizing profits and minimizing costs. In its globalized corporate form, capitalism has been able to relentlessly realize this form of instrumental reasoning on a large scale – and thereby show itself as one of the most destructive and undemocratic economic system humans have ever come up with.

Unfortunately, neither propaganda nor abstract economic theory can help us to grasp this fact. The reason is primarily that the latter do not really speak to the false theories of human nature capitalism presupposes. Nor do many of them elaborate capitalism’s legitimating normative-moral or political origins. Most crucially, they are often silent regarding the devastating impact that it has had on the environment since it first emerged during the course of the eighteenth and nineteenth centuries. As Chomsky insightfully puts it, “There is “capitalism” and then there is “really existing capitalism.” What then is “really existing capitalism’?

Thomas Piketty’s Capital in the Twenty-First Century gives us a few clues, though not by any means, the whole picture. Replete with startling empirical evidence in the form of charts, graphs, informative statistics, mathematical-logical expressions and astute critical-historical analyses, Piketty’s work draws a number of sobering conclusions about the present dynamics of wealth and income distribution that exposes not merely the dark underside of capitalism but a central contradiction within it. Thus, Piketty concludes “. . . wealth accumulated in the past grows more rapidly than output and wages. This inequality expresses a fundamental logical contradiction. The entrepreneur inevitably tends to become a rentier, more and more dominant over those who own nothing but their labor. Once constituted, capital reproduces itself faster than output increases. The past devours the future.”

The past devours the future. But, what if the bizarre inverted logic of capitalism has always been its real point? What if, under the rubric of capitalism, the powerful elite are given permission to act as if it simply doesn’t matter whether their ever-expanding wealth might actually devour the future, or “wear the world out faster” to borrow a phrase from Orwell? Do they not often appear to live in an all-consuming present – get what you can for yourself right now, and don’t worry about others, or even about tomorrow? Moreover, is not such an attitude, sanctioned by capitalism, the reason why this particular economic system requires endless cycles of economic crisis?

Perhaps Piketty’s point is that if it doesn’t matter to the elite, it should at least matter to us. But if it does matter, then it is up to the rest of us – including experts like Piketty who grasp the reality of capitalism better than anyone else – to imagine real alternatives to such an economic system, to think outside of the present paradigm of endless development, profit maximization and disastrous austerity measures imposed on whole populations. Despite the apparently glaring “logical” contradiction within capitalism, Piketty still holds to the idea that it can be properly disciplined through a progressive annual tax on wealth. It is not the conclusion he should have reached given his thorough and prescient analysis.

Looking at the history of capitalism, it is difficult not to conclude that growing inequality expresses a fundamental property of and not a contradiction within capitalism.

Of course, Piketty is by no means alone in wanting to save capitalism from itself. Capitalism – no matter what its excesses, or how destructive it is for life or democracy – is invariably held as our default economic system, grudgingly acceded to even by popular left-oriented economists such as Paul Krugman, Nouriel Roubini or Joseph Stiglitz. As Chrystia Freeland unabashedly concludes in Plutocrats, The Rise of the New Global Super-Rich and the Fall of Everyone Else, despite all its faults, we continue to need capitalism because, “very much like democracy,” it is “the best system we’ve figured out so far.” [1] Thus, if capitalism appears to go wrong, this is not because it is grounded on a misreading of history, internal contradictions, false theories about nature or human nature, or misguided moral and political presuppositions. Rather, the excesses of capitalism are simply a question of “bad management’ and a political unwillingness to properly regulate it by imposing the right sort of checks and balances.

In fact, Piketty’s proposed wealth tax solution may do more to obscure than resolve the really existing contradictions of capitalism. Looking at the history of capitalism, it is difficult not to conclude that growing inequality expresses a fundamental property of  and not a contradiction within capitalism. Inequality is built into capitalism. If there is a contradiction here it is a material not a logical one. In other words, it is the contradiction between an economic system that is radically indifferent to the health and well-being of the planet as a whole versus the economic, moral and environmental obligation to preserve and sustain such health and well-being.

If I am right that the inner logic of capitalism inevitably leads to a hegemonic, macro-structural world-system of unequal human social, political and economic relations guided by elite greed that does not reflect the best interests of the majority of people, the common good or indeed the good of the planet itself, then Piketty’s assumption that we could ever regain control over an “endless inegalitarian spiral’ by imposing a progressive tax on capital seems, is at best, rather fanciful. A more fitting conclusion in the aftermath of the 2008 financial crisis and the efforts of the elite to profit from the latter would be to ask the question whether we should continue advocating for a capitalist system that glorifies profit over people or start thinking about how to reorganize our economy around common goods such as the health and well-being of our present world.

Instead, many contemporary economists repeatedly tell us that our only tenable alternative is to tame capitalist excess through regulative initiatives. This has been done before and it can be done again, the argument goes. Thus, it is claimed that we can and did rein-in or mitigate the severity of capitalist exploitation, and the massive wealth and income disparities that followed from it. However, it should now be abundantly clear that the internal and structural logic of exploitation, wealth-income disparities and the profit-oriented colonization of social and political relations can only be regulated for short periods. It can never be fundamentally altered. Indeed, as Piketty has persuasively argued, relentless exploitation, colonization and massive inequality were only temporarily pre-empted by a war economy and FDR’s regulatory initiatives. By the late 1970’s, the internal logic of capitalism had re-established its hegemonic status and all of the built-in excesses of the capitalist economic system once again became normalized and necessary.

What if . . . we are all conditioned to see the world in terms of individual economic self-interest rather than in terms of common human good or planetary limits, health and equilibrium?

What this tells us is that regulatory reform of capitalism will only be allowed for a brief period. In other words, to the extent that it can obscure or prevent us from perceiving the inner logic of a system of structured inequality, or distract us from the most deleterious effects of capitalism on the environment and on human health and well-being, minimal regulation may be deemed necessary by the elite for a short period of time. However, as Naomi Kleinhas convincingly argued, the “collective vertigo’ caused by wars, economic upheaval, environmental or political crisis, environmental disasters can also be exploited as the perfect means through which a capitalist system of greed takes over markets, amasses fabulous fortunes and bankrupts the wealth of the commons.

Perhaps the refusal to ask critical questions about the viability of capitalism might be explained by the fact that even today many economists still hold onto the mythic assumption that the “impartial” self-regulating market is no more than a theoretical expression of the “order of human nature” itself and not, after all, a product of powerful political and moneyed interests. This belief has distant origins in Thomas Hobbes fear-inspired mechanistic account of human beings who in their natural state are war-like and driven by self-interest. Not only does the latter perspective resonate in many manifestations of capitalist theory, it also underscores a desire to replicate in economic theory what nature apparently prescribes – a war-like disposition disciplined through competitive markets based on innate selfishness. But what if the incapacity to imagine alternatives is not because we are naturally selfish, but simply a function of the reality that in capitalist societies we are all conditioned to see the world in terms of individual economic self-interest rather than in terms of common human good or planetary limits, health and equilibrium?

This perfectly predictable inversion, where government becomes a handmaid to moneyed interest, is precisely the “logic of a capitalist system.”

Over time, the promotion of selfishness as a virtue not only changes the way we look at ourselves, it influences the way we relate to each other and to the planet itself. Instead of citizens who define themselves in relation to common goods, we are reduced, under the selfish orientation of capitalism, to aggregates of self-interested atomistic individuals encouraged to believe that we can continue a lifetime of limitless consumption. Those who are entirely left out of the consumer game – the increasing numbers of homeless, stateless refugees, destitute and imprisoned whose day-to-day life is taken up by the fight for mere survival – are the necessary residue of a global capitalist system.

From its inception, capitalist economic theory has pushed the idea that the market would only be able to regulate itself if it were not subject to external and coercive government interference or regulation. However, the reality is that capitalist accumulation was never actually severed from politics or government, but invariably parasitic upon it. It has always been intimately tied to publicly funded government tax-breaks and subsidies, to war, colonial-imperial expansion, and industrial ambitions. What happened is simply that massive capitalist accumulation was allowed to entirely invert the power relation between moneyed interests and government. Thus, an elite class of bankers, financiers and industrialists (eventually expressing itself through corporate ownership) have become so powerful, they are able to coerce governments and states to go along with whatever is in their minority interest. This perfectly predictable inversion, where government becomes a handmaid to moneyed interest, is precisely the “logic of a capitalist system,” which renders any suggestion of government imposed progressive taxation rather fantastical.

Related to this, faith in the promise of capitalism might also have to do with a kind of wilful blindness about the actual origins of capital. As Karl Polyanyi reminds us, many scholars and economists tenaciously hold to Adam Smith’s idea that the division of labor has always been based upon markets of some kind because our “propensity to barter, truck and exchange one thing for another” is simply ingrainedin the natural order of things. But, clearly we do not need capitalism – the privatizing of wealth and the socializing of costs – to show us how to barter, truck or trade goods. Indeed, capitalism is actually inimical to bartering or trading, precisely because it is driven by individual profit and monopolization, not by the fair exchange of goods. The FTA (Free Trade Agreements), NAFTA (North American Free Trade Agreement) and TPP (Trans-Pacific Partnership) are the awful modern exemplars here.

There is nothing impartial about early capitalism’s inextricable relation to colonialism, slavery or plunder for private gain.

Polyani quickly dispels Smith’s historical misreading of the division of labor as structured by capitalism by reminding us that up to Smith’s time such a propensity toward the individual pursuit of unfettered profit based on wage labor “had hardly shown up on a considerable scale in the life of any observed community and had remained, at best, a subordinate feature of economic life . . . “[2]. The historical and anthropological evidence clearly suggests that it was not until the industrial age that the capitalist-inspired “wealth of nations” was realized by a hegemonic economic system guided by self-interested priorities and the exploitation of material goods and human beings in a relentless pursuit of profit for the few. Before this period, our economics were oriented by social, community, tribal and familial concerns that were considered far more important than the private possession and accumulation of goods based wholly on economic self-interest.

A more precise and broad-based historical study would conclude that, in point of fact, there isn’t anything in nature, the human condition, morality or history that necessitates the adoption of capitalism. It would also disclose that there is nothingimpartial about early capitalism’s inextricable relation to colonialism, slavery or plunder for private gain. In point of fact, the historical reality is that market capitalism is intimately tied to a colonial-imperialist political agenda. This imperialist history clearly demonstrates that there is also very little that is “free” about a “free-market” that derives its freedom to accumulate wealth by way of slave labor, slave wages, debt bondage, unjust land confiscation and the expropriation of common lands and resources into private hands. In America, the so-called “free market” wedded private self-interested exploitation of labor with imperialist state interest on a scale that dramatically dwarfed the brutality of old-world Europe. It should not be in the least surprising then that the slave plantation might capture the essence of our modern global capitalist system, insofar as it is built on the premise of extracting maximum labor at minimal cost.

Of course when one looks at history, it is not immediately apparent that the “founding fathers’ of capitalism – John Locke, Adam Smith, David Ricardo – wanted to intentionally construct a system that would entrench massive inequality. The latter figures were highly articulate, systematic, future-oriented thinkers who believed that private property, free trade, competition and laissez-faire capitalism were inherently good, and had an unlimited potential to raise the general welfare of society. However, even here, those who enjoyed the fruits of a capitalist political economy were relatively few – certainly not the working class or slaves. Each of these illustrious thinkers exemplifies in his writings the material contradictions that capitalism represents.

To be fair, from the perspective of the 18th and 19th centuries, the planet did appear to have unlimited potential for growth, not to mention individual and social enrichment.

Moreover, the science of pollution and toxicity of industrial chemicals 200 years ago was nowhere near the advanced state it is now. However, the material contradictions of capitalism are starkly illustrated even in its earliest philosophical foundations. Thus, on the one hand, John Locke’s (1632-1704) political philosophy begins (as against Hobbes’) with the idea that in our “original state of nature,” we are not in a state of war, but in a state of ” ‘perfect freedom’ to order our action, and dispose of our possessions and persons, as we think fit, within the bounds of the law of nature, without asking leave, or depending upon the will of any other man.” This state of nature, Locke believed, is also a state “. . . of equality, wherein all the power and jurisdiction is reciprocal, no one having more than another.” [3]

However, on the other hand, not all people were heir to such “perfect freedom” in their “natural state” or otherwise; nor did they have possessions or reciprocal power. In fact, a good many of them were not even treated as “persons” or individuals, but as mere “savages.” There is nothing fair or equal about the fact that Locke’s tremendous wealth was directly the result of investments in the silk and slave trade. Indeed, he believed that important, moneyed land barons should form “a government of slave-owners” and suggested that children over 3 years of age who were from families on relief should attend “working schools” so they would be “from infancy . . . inured to work” [4]. Appearances notwithstanding, the “sacred and inviolable right to property” that Locke espouses is not something either slaves or the laboring classes were granted. The “perfect freedom” was indeed “perfect servitude” of those who were not white Europeans.

Behind the wonderful talk of liberal values, “increasing the common stock of man through money” and individual rights, Locke put forward an absolutist theory of property that would provide legitimacy to the imperialist ambitions of England and wealthy English landowners in America. The problem is that Locke’s morally grounded theory of the right to private property presupposes the expropriation of ancestral native lands, the existence of slavery and the impoverishment of laboring classes. As Ronald Wright has astutely noted, quoting from Senator Dawes in his Allotment Act, the problem with “Indians” is that they lacked “selfishness, which is the bottom of civilization”![5] What we are compelled to conclude here is that these historical facts are not unpredictable events or anomalies of capitalism, but perspectives and practices intrinsic to the expansion of a capitalist economy.

The unavoidable question is why Smith advocated a “capitalist economic system” that glorified unbridled competition – a practice he intuited would inevitably corrupt our “natural sentiments” and deepen a proclivity toward selfish behaviour?

The Scottish Enlightenment thinker Adam Smith (1723-1790) believed that not only did competition mitigate the ruthlessness of self-interest, but the providential “invisible hand of the market” would ensure that in promoting our self-interest we would be simultaneously promoting the interests of society, whether we intended to do so or not. But, the rational or enlightened self-interest of Smith’s economic man breaks down fairly quickly within the logic of monopolistic capitalism. Smith, like Piketty, is prescient enough to caution about the monopolistic trajectory of capitalism and the potential that industry and business had for influencing politics in their favour over the good of consumers and society as a whole. Moreover, against the logic of unfettered capitalist accumulation, he also thought laborers should be well paid and the rich and indolent taxed for the benefit of the poor.

At the same time, Smith’s “merchant” is not much different than the modern corporate CEO. A merchant he explains “. . . is not necessarily a citizen of any particular country. It is in a great measure indifferent to him from what place he carries on his trade; and a very trifling disgust will make him remove his capital, and together with it all the industry which it supports, from one country to another.” [6]It is not hard to imagine that the “trifling disgust” classical merchants or modern CEOs experience is a consequence of having unions or governments interfere with their profits by demanding workers receive a living wage.

In the end, the unavoidable question is why Smith advocated a “capitalist economic system” that glorified unbridled competition – a practice he intuited would inevitably corrupt our “natural sentiments” and deepen a proclivity toward selfish behaviour? If the answer is that it is the self-correcting, providential “invisible hand” that reconciles selfishness and the general welfare of society, then Smith’s entire economic system rests on a fiction: There just is no such thing as an “invisible hand,” nor has there ever been any such providential or moral self-correcting mechanism within capitalist economics. Given this, it is difficult not to conclude that Smith (again, like Piketty) did, in fact, fully grasp the adverse effects and inherent material contradictions of capitalism. Nevertheless, he held steadfastly to the idea that a phantasmal occult force (the invisible hand) would enable our natural sympathy with the plight of others and our natural self-interested expression of individual freedom to live peacefully together.

What is startling is not how different, but how similar the speculative capitalist mindset has always been. The early 19th century economist, broker and speculator David Ricardo “. . . made the bulk of his fortune as a result of speculation on the outcome of the Battle of Waterloo, using methods that today would result in prosecution for insider trading and market manipulation.”[7] It is not a great leap from insider trading (which Milton Friedman, much later, enthusiastically endorsed) to securities fraud, negligent subprime mortgage lending, unregulated credit default swaps and so on. But it is also evidently true that wealth is  power – power cashed out at the political level. Ricardo, who was able to use his largesse to buy a seat in the UK Parliament, would probably not have had any problem with the Supreme CourtCitizens United decision to remove limits on corporate political donations. Perhaps we have here one of the earliest exemplars of how moneyed interest, power and political ambition are easily woven together in a capitalist political economy. At any rate, it is clear that the very visible hand of the elite class inevitably renders government “by and for the people’ pretty much irrelevant – or better, invisible.

As for economic theory, Ricardo’s assumption that with social progress, the price of labor is “dear when it is scarce and cheap when it is plentiful” might explain why today the superrich have “stopped worrying and learned to love unemployment and under-employment.” As the rich have become even richer since the 2007 financial crisis, the global unemployment rate has steadily increased such that by 2015, 205 million people will be out of work – and this doesn’t even touch those who have given up looking for a job. Of course, Ricardo, like Marx after him, was clever enough to recognize that the interests of wealthy landowners were often in direct opposition to the good of society and would inevitably create tension and upheaval. This did not, however, prevent him from advocating for the abolition of the Poor Law which, he believed, encouraged people to be lazy and irresponsible – “are there no prisons? . . . are there no workhouses?”

Despite some indications to the contrary, Hobbes’ theory of human nature is unambiguously presupposed in Locke, Smith and Ricardo’s elaboration of capitalist political economy. All are essentially in agreement with the idea that we are “by nature” selfish creatures. Perhaps it is only in this sense we can be said to be “equals” – we are all equally selfish. However, such a presupposition, by any objective measure, is simply false. We know today, from abundant empirical, sociological, psychological, genetic, archaeological and anthropological evidence, that Hobbes’ theory of human nature as intrinsically “selfish” is deeply flawed. We are not “naturally” selfish – though we can, indeed, learn to be so. In other words, within a capitalist system it can become trueover over the course of time that an elite few will be chiefly oriented by greed, narcissism or selfishness – and some of the latter not so very far from the “squeezing, wrenching, grasping, scraping, clutching, covetous old sinners!” Dickens describes Mr. “Scrooge” as in A Christmas Carol. Of course, today the latter are no longer viewed as “sinners.” The real problem is that in our present world they are the “glorified masters” of our economies and governments. They are continuously praised, deferred to, considered “above the laws of the land” and allowed to live in a world of unabashed opulence entirely walled off from the rabble of mankind. Succinctly put, in capitalism, the greedy of the world have discovered their ideal legitimating cover: the promotion of a self-serving economics that turns the vice of selfishness into the highest virtue human beings can realize! [8]

History aside, from our own contemporary perspective, we can get a sense of “really existing capitalism’ by virtue of the following thought-experiment, which reveals the latter in its unadorned state. Imagine that we were able, right now, to ask the 7 or so billion people living on the planet whether they would choose an economic system that would inevitably lead to massive wealth and income inequalities, that would severely limit equal opportunity, that would force whole populations to live under perpetual economic austerity, that would erode any possibility of meaningful and democratic political participation, that would devastate the health of the planet and the human body while externalizing the costs of such destruction onto everyone, with the exception of a very privileged few.

Now . . . how many people do you think would actually opt for such an arrangement? Honest answer: Almost no one! The only people who would agree to such a set of conditions would be an infinitesimally small group whose present privileged economic status would be protected and furthered by maintaining the status quo. The fact is that though there are many manifestations of the capitalist system, the intentional logic of capitalism always was, and still is, the same: to protect and perpetuate the power, status and privilege of the few, while impoverishing everyone else.

Given this, you might think that we would seriously question anyone who asserts that capitalism best captures or reflects the essential capabilities, wants, desires or needs of human beings – or that it, in any way, helps to preserve or sustain the resources of the planet for future generations. If anything, capitalism has become the medium where what is worst in us is magnified and given legitimacy – materialism, greed, indifference to the suffering of others, deceitfulness and hubris – while diminishing the importance of justice, benevolence and environmental stewardship. Hopefully, Piketty’s book will be a wake-up call – not a call to fix capitalism, but to overcome it. The fact is that even if a tax on wealth could somehow reconcile the logical contradiction within capitalism, it will do nothing to prevent corporations from their “race to exploit what is left” [9]; it will not stop them from moving us closer to ecological disaster by extracting oil from bituminous sands or minerals from impoverished third world countries; it will not deter the Wall Street mega banks like Goldman Sachs, the “vampire squid wrapped around the face of humanity” (to borrow Matt Taibbi’s startling and vivid description) from sucking the life out of national economies; it will not impede the chemical industry from polluting the environment and using whole populations as unwitting research objects for profit; it will not avert the continuing dissolution of democracy by the superrich Koch brothers . . . and on and on.

Notwithstanding all that has been said, it is still conceivable that we could reverse our present “conditioning” by thinking and acting in different ways – by recognizing that, progressively, with the help of others, we could cultivate radically different perspectives and practices (economic and otherwise). But any such effort must assume that we are also acutely aware of the ubiquity and the powerful force of capitalist propaganda. As Henry Giroux reminds us “dominant power works relentlessly through its major cultural apparatuses to hide, mischaracterize or lampoon resistance, dissent and critically engaged social movements. This is done, in part, by sanitizing public memory and erasing critical knowledge and oppositional struggles from newspapers, radio, television, film and all those cultural institutions that engage in systemic forms of education and memory work.”[10]

Above all, the possibility of alternative economic visions, perspectives and practices have to be grounded in the reality that we share a limited world, and that we are and have always been capable of creating an economic system and public policies that preserve the health and well-being of the planet and all of the creatures that inhabit it.

Nancy Scheper-Hughes Responds to Our Profile, ‘The Organ Detective’ (Pacific Standard)

 • July 15, 2014 • 7:32 PM

The chair of the doctoral program in medical anthropology at the University of California-Berkeley was written about in the July/August issue of Pacific Standard.

In his profile of me (“The Organ Detective,” July/August), Ethan Wattersquotes sources indicating that I have a deep animus toward the medical establishment. I have always worked closely with surgeons, pathologists, psychiatrists, pediatricians, and transplant professionals. I have co-authored numerous articles with physicians and transplant surgeons. In 2007, I was offered a McKnight Presidential Endowed Chair and Professorship at the University of Minnesota, with a primary appointment in the Department of Surgery. I declined, regretfully, but I believe the offer reflected that school’s faith in my ability to play a positive role in the training of medical students (including surgeons) in medical anthropological concepts and methods bearing on ethical clinical practice.

In different ways, and from very different political, moral, and professional positions, together we were able to bring the sad story into international public discourse.

Watters also writes about the scandal surrounding the Abu Kabir Forensic Institute, the sole facility in Israel that conducts official autopsies. But he leaves out crucial details. For more than two decades, the Israeli government denied accusations that pathologists at Abu Kabir were secretly harvesting organs, bone, skin, and other tissues from the bodies of “enemy” combatants as well as Israeli citizens. Israeli officials dismissed these charges as “blood libel” against the state. In the early 1990s, a Swedish journalist named Donald Bostrom and I, independently of each other, began investigating allegations of human rights abuses at the institute, Bostrom in the West Bank and me in Israel. Neither Bostrom nor I knew that an internal whistle-blower, Chen Kugel, a young Israeli forensic pathologist and military officer at Abu Kabir, was working behind the scenes to stop the plunder of dead bodies at the institute. As Kugel observed, hearts, glands, heads, and even skin grafts of tattoos were being stockpiled and sold for poorly specified “science,” or kept in a kind of curiosity museum.

In 2009, after Bostrom sparked an international controversy with an article in the Swedish newspaper Aftonbladet, I released an audio interview with Yehuda Hiss, the longtime director of Abu Kabir, in which he acknowledged the illicit harvesting. This resulted in an unlikely and uneasy collaboration among Kugel, Bostrom, and me. In different ways, and from very different political, moral, and professional positions, together we were able to bring the sad story into international public discourse. In the end, the Israeli government admitted to the crimes committed against Jewish as well as Muslim, Christian, and immigrant dead bodies. Yehuda Hiss was removed, and the heroic whistle-blower, Dr. Kugel, was appointed Hiss’ successor. As a result, all dead bodies at Abu Kabir are safe and protected.

My discipline’s reticence toward actively engaged scholarship has sometimes turned anthropologists into bystanders when crimes against humanity are taking place.

NASA’s Orbiting Carbon Observatory-2: Data to lead scientists forward into the past

Date: July 20, 2014

Summary: NASA’s Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more than great data to figure that out.

Scientists will use measurements from the Orbiting Carbon Observatory-2 to track atmospheric carbon dioxide to sources such as these wildfires in Siberia, whose smoke plumes quickly carry the greenhouse gas worldwide. The fires were imaged on May 18 by NASA’s Moderate Resolution Imaging Spectrometer instrument on the Terra satellite. Credit: NASA/LANCE/EOSDIS Rapid Response 

NASA’s Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more than great data to figure that out.

“In a sense, you’re trying to go backward in time and space,” said David Baker, a scientist at Colorado State University in Fort Collins. “You’re reversing the flow of the winds to determine when and where the input of carbon at the Earth’s surface had to be to give you the measurements you see now.”

Harry Potter used a magical time turner to travel to the past. Atmospheric scientists use a type of computer model called a chemical transport model. It combines the atmospheric processes found in a climate model with additional information on important chemical compounds, including their reactions, their sources on Earth’s surface and the processes that remove them from the air, known as sinks.

Baker used the example of a forest fire to explain how a chemical transport model works. “Where the fire is, at that point in time, you get a pulse of carbon dioxide in the atmosphere from the burning carbon in wood. The model’s winds blow it along, and mixing processes dilute it through the atmosphere. It gradually gets mixed into a wider and wider plume that eventually gets blown around the world.”

Some models can be run backward in time — from a point in the plume back to the fire, in other words — to search for the sources of airborne carbon dioxide. The reactions and processes that must be modeled are so complex that researchers often cycle their chemical transport models backward and forward through the same time period dozens of times, adjusting the model as each set of results reveals new clues. “You basically start crawling toward a solution,” Baker said. “You may not be crawling straight toward the best answer, but you course-correct along the way.”

Lesley Ott, a climate modeler at NASA’s Goddard Space Flight Center, Greenbelt, Maryland, noted that simulating carbon dioxide’s atmospheric transport correctly is a prerequisite for improving the way global climate models simulate the carbon cycle and how it will change with our changing climate. “If you get the transport piece right, then you can understand the piece about sources and sinks,” she said. “More and better-quality data from OCO-2 are going to create better characterization of global carbon.”

Baker noted that the volume of data provided by OCO-2 will improve knowledge of carbon processes on a finer scale than is currently possible. “With all that coverage, we’ll be able to resolve what’s going on at the regional scale,” Baker said, referring to areas the size of Texas or France. “That will help us understand better how the forests and oceans take up carbon. There are various competing processes, and right now we’re not sure which ones are most important.”

Ott pointed out that improving the way global climate models represent carbon dioxide provides benefits far beyond the scientific research community. “Trying to figure out what national and international responses to climate change should be is really hard,” she said. “Politicians need answers quickly. Right now we have to trust a very small number of carbon dioxide observations. We’re going to have a lot better coverage because so much more data is coming, and we may be able to see in better detail features of the carbon cycle that were missed before.” Taking those OCO-2 data backward in time may be the next step forward on the road to understanding and adapting to climate change.

A 10-year endeavor: NASA’s Aura and climate change

Date: July 18, 2014

Source: NASA/Jet Propulsion Laboratory

Summary: Celebrating its 10th anniversary this week, NASA’s Aura satellite and its four onboard instruments measure some of the climate agents in the atmosphere, including greenhouse gases, clouds and dust particles. These global datasets provide clues that help scientists understand how Earth’s climate has varied and how it will continue to change.

Nitrogen and oxygen make up nearly 99 percent of Earth’s atmosphere. The remaining one percent comprises gases that — although present in small concentrations — can have a big impact on life on Earth. Trace gases called greenhouse gases warm the surface, making it habitable for humans, plants and animals. But these greenhouse gases, as well as clouds and tiny particles called aerosols in the atmosphere, also play vital roles in Earth’s complex climate system.

Celebrating its 10th anniversary this week, NASA’s Aura satellite and its four onboard instruments measure some of the climate agents in the atmosphere, including greenhouse gases, clouds and dust particles. These global datasets provide clues that help scientists understand how Earth’s climate has varied and how it will continue to change.

Measuring Greenhouse Gases

When the sun shines on Earth, some of the light reaches and warms the surface. The surface then radiates this heat back outward, and greenhouse gases stop some of the heat from escaping to space, keeping the surface warm. Greenhouse gases are necessary to keep Earth at a habitable temperature, but since the Industrial Revolution, greenhouse gases have increased substantially, causing an increase in temperature. Aura provides measurements of greenhouse gases such as ozone and water vapor, helping scientists understand the gases that influence climate.

People, plants and animals live in the lowest layer of the atmosphere, called the troposphere. In this layer, the temperature decreases with altitude, as mountain climbers experience. The temperature starts to increase again at the tropopause, about 8 miles (12.9 kilometers) above the surface at temperate latitudes, like those of the United States and Europe. Closer to the equator, the tropopause is about 11 miles (17.7 kilometers) from the surface.

In the middle and upper troposphere, ozone acts as a greenhouse gas, trapping heat in Earth’s atmosphere. Tropospheric ozone is one of the most important human-influenced greenhouse gases.

Aura’s Tropospheric Emission Spectrometer (TES) instrument, built and managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, delivers global maps showing annual averages of the heat absorbed by ozone, in particular in the mid troposphere. Using these maps and computer models, researchers learned that ozone trapped different amounts of heat in Earth’s atmosphere depending on its geographic location. For instance, ozone appeared to be a more effective greenhouse gas over hotter regions like the tropics and cloud-free regions like the Middle East.

“If you want to understand climate change, you need to monitor the greenhouse gases and how they change over time,” said Bryan Duncan, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Along with ozone, Aura measures other important greenhouse gases such as methane, carbon dioxide and water vapor.

Improving Climate Models

In addition to greenhouse gases, Aura measures several other constituents relevant to climate — smoke, dust and clouds including the ice particles within the clouds — that are important for testing and improving climate models.

“If you don’t have any data, then you don’t know if the models are right or not,” said Anne Douglass, Aura project scientist at Goddard. “The models can only be as good as your knowledge.”

The way clouds affect Earth’s climate depends on their altitude and latitude. Two of Aura’s instruments have provided information about tropical clouds. Like greenhouse gases, high, thin clouds in the tropics absorb some of Earth’s outgoing heat and warm the surface. Aura’s High Resolution Dynamics Limb Sounder (HIRDLS) instrument provided global maps showing cirrus clouds in the upper altitudes in the tropics. Researchers have used these data along with data records from previous satellites going back to 1985 to show that the tropical cirrus cloud distribution has been steady, giving scientists information about the interplay among water vapor, ice and the life cycle of these clouds.

Aura’s Microwave Limb Sounder (MLS) instrument, also built and managed by JPL, made the first global measurements of cloud ice content in the upper troposphere, providing new data input for climate models. MLS showed cloud ice is often present over warm oceans. Along with satellite rainfall data, MLS shows that dirty, polluted clouds rain less than clean clouds. The novel relationships obtained from HIRDLS and MLS connect ocean temperatures with clouds and ice and quantify effects of pollution on tropical rainfall — which are important assessments for climate models.

Aerosols influence climate, but their influence is challenging to decipher because they play several different roles. Aerosols reflect radiation from the sun back into space; this tends to cool Earth’s surface. Aerosols such as dust and smoke also absorb radiation and heat the atmosphere where they are concentrated. Aura’s Ozone Monitoring Instrument (OMI) is especially good at observing these absorbing aerosols above clouds and bright deserts. Both OMI and TES also provide data on gases, such as sulfur dioxide and ammonia, which are primary ingredients for other types of less-absorbing aerosols. Aura data, in conjunction with other satellite data, are helping scientists understand how aerosols interact with incoming sunlight in Earth’s atmosphere; this, in turn, helps scientists improve long-term predictions in climate models.

Learning from Long Data Sets

Researchers investigated how natural phenomena such as El Niño affect tropospheric ozone concentrations — a study made possible by Aura’s extensive data set.

El Niño is an irregularly occurring phenomenon associated with warm ocean currents near the Pacific coast of South America that changes the pattern of tropical rainfall. The occasional appearance of areas of warmer temperatures in the Pacific Ocean shifts the stormiest area from the west to the east; the region of upward motion — a hallmark of low ozone concentrations over the ocean — moves along with it.

Without a decade-long data record, researchers would not be able to conduct such a study. Using the extensive data set, researchers are able to separate the response of ozone concentrations to the changes in human activity, such as biomass burning, from its response to natural forcing such as El Niño.

“Studies like these that investigate how the composition of the troposphere responds to a natural variation are important for understanding how the Earth system will respond to other forcing, potentially including changes in climate,” said Douglass. “The Earth system is complex, and Aura’s breadth and the length of the composition data record help us to understand this important part of the system.”

Ten-year endeavor: NASA’s Aura tracks pollutants

Date: July 18, 2014

Source: NASA/Jet Propulsion Laboratory

Summary: NASA’s Aura satellite, celebrating its 10th anniversary on July 15, has provided vital data about the cause, concentrations and impact of major air pollutants. With instruments providing key measurements of various gases — including two built and managed by NASA’s Jet Propulsion Laboratory: the Tropospheric Emission Spectrometer (TES) and Microwave Limb Sounder (MLS) — Aura gives a comprehensive view of one of the most important parts of Earth — the atmosphere.

NASA’s Aura satellite, celebrating its 10th anniversary on July 15, has provided vital data about the cause, concentrations and impact of major air pollutants. With instruments providing key measurements of various gases — including two built and managed by NASA’s Jet Propulsion Laboratory: the Tropospheric Emission Spectrometer (TES) and Microwave Limb Sounder (MLS) — Aura gives a comprehensive view of one of the most important parts of Earth — the atmosphere.

Aura has improved our understanding of ozone, a versatile gas that both benefits and harms the atmosphere, depending on its location. Near the ground, ozone is a pollutant that damages plants and can decrease lung function in humans. Somewhat higher in the atmosphere, ozone affects climate as a greenhouse gas. Aura’s TES instrument provides measurements of ozone and other greenhouse gases.

The majority of ozone, about 90 percent, is even higher — in the stratosphere, 12 to 90 miles above the surface — where it shields us from the sun’s ultraviolet light and makes life possible on Earth. Over the Antarctic, cold temperatures and human-produced chlorine gases destroy ozone each spring. Scientists use Aura’s Microwave Limb Sounder (MLS) instrument to measure ozone and other trace gases in and around the ozone hole every year. In 2006 and 2011, Aura’s instruments revealed two of the largest and deepest ozone holes in the past decade, and also helped scientists understand the different causes of the two large holes.

Shortly after Aura’s launch, the Ozone Monitoring Instrument (OMI) began monitoring levels of another major pollutant — nitrogen dioxide. This brownish gas can lead to respiratory problems and is an ingredient in ground-level ozone pollution. OMI data show that nitrogen dioxide levels in the United States decreased 4 percent per year from 2005 to 2010, a time when stricter policies on power plant and vehicle emissions came into effect. As a result, concentrations of ground-level ozone also decreased. During the same period, global nitrogen dioxide levels increased a little over half a percent per year. China’s level increased about 6 percent per year.

OMI also measures sulfur dioxide, a gas that combines with other chemicals in clouds to produce acid rain or reacts to form sulfate aerosols, which affect health and climate. OMI has identified large concentrations of sulfur dioxide around power plants and volcanoes.

Aura’s decade of work has set the stage for future air quality monitoring instruments. The European Space Agency will be launching the follow-up TROPOspheric Monitoring Instrument, which will continue Aura’s OMI measurements with better ground resolution and precision. NASA plans to launch the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument, which will observe ozone, nitrogen dioxide, sulfur dioxide, formaldehyde and aerosols over the United States, Canada and Mexico.

“Pollution is a global issue because it can travel long distances in the wind,” said Anne Douglass, Aura project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “By using satellites, we can develop a valuable global inventory of pollutants and understand how air quality may be changing.”

José Mujica – 17.jul.2014

Narração de abertura [EM OFF]: José Alberto Mujica Cordano tem 79 anos. Nasceu em Montevidéu, no Uruguai.

Pepe Mujica, como é conhecido, iniciou sua militância política ainda jovem, no grupo armado Tupamaro, que pretendia chegar ao poder inspirado pela revolução cubana.

Foi preso diversas vezes na década de 70 pela ditadura uruguaia. Permaneceu encarcerado por 14 anos. Nesse período, passou 2 anos em uma solitária no fundo de um poço.

Em 1985, Pepe Mujica foi anistiado e ganhou a liberdade. Alguns anos depois, ajudou a fundar um partido de esquerda, o Movimento de Participação Popular.

Mujica elegeu-se deputado em 1994. Cinco anos depois, foi eleito senador.

Em 2005, o então presidente do Uruguai Tabaré Vázquez o nomeou ministro da Pecuária, Agricultura e Pesca. Ganhou a simpatia da população com sua capacidade de diálogo e modo franco de expressar opiniões

Pepe Mujica deixou o ministério em 2008. No ano seguinte, elegeu-se presidente do Uruguai, cargo que exerce até hoje.

Folha/UOL: Olá. Bem-vindo a mais um Poder e Política Entrevista. Este programa é uma realização do jornal Folha de São Paulo e do Portal UOL. A gravação desta edição do Poder e Política está sendo realizada, excepcionalmente, na Embaixada do Uruguai em Brasília, porque o entrevistado desta edição do Poder e Política é o presidente do Uruguai, José Mujica.

Folha/UOL: Olá, presidente. Como vai?
José Mujica: É um prazer cumprimentá-lo.

Muito obrigado. É um privilégio tê-lo aqui no Poder e Política. Como o senhor define a relação hoje entre o Brasil e o Uruguai?
Eu acho que é uma relação cordial, de muito reconhecimento, apesar da diferença notória de recursos, de tamanho. Mas o Brasil, com muita inteligência, olha para o Sul como parte componente de seu espaço geopolítico natural.

Às vezes, no Cone Sul, na América Latina, nota-se um sentimento sobre o Brasil ser um país com interesses imperialistas nessa região. Às vezes Algumas pessoas dizem isso. O senhor acha que existe esse sentimento?
Sim, algo assim pode acontecer. Eu acredito que é resultado dos inevitáveis flertes nacionalistas que existem por todas as partes. A atitude imperial do Brasil pode ter sido consequência de sua história, é um país que teve um imperador que declarou a independência, que herdou a tradição da Casa de Bragança. E teve um Estado constituído muito cedo, de forma um pouco europeia. Que teve uma longa discussão de fronteiras, muito inteligente para os interesses do Brasil. Certamente, formou uma visão cultural desse tipo. Mas o Brasil de hoje encontra-se imerso em uma época diferente. Todos chegamos atrasados, o mundo está desenvolvido. Ou, pelo menos, uma parte importante dele. E o mais inteligente do Brasil é que percebe que, embora seja grande, precisa de um todo para acompanhá-lo na tentativa de fazer algo na negociação mundial. E, aqueles que não somos o Brasil, estamos conscientes de que precisamos do Brasil para cumprir esse papel. Mas o problema está dentro do Brasil. Por quê? Porque há uma corrente de pensamento válida que diz que “o Brasil é muito grande e ainda temos de integrarmo-nos como país.” E talvez tenham razão, mas já é tarde.

*Com relação ao Uruguai, o Uruguai hoje está satisfeito com a relação geral que tem com o Brasil, sobretudo no aspecto econômico? *
Sim, sempre encontramos vontade política para superar as dificuldades em um país grande, com organização federal, onde às vezes surgem curtos-circuitos com os Estados e o governo central. Sempre com paciência, tenta diminuir o nível das contradições. Por exemplo, quando há a colheita do arroz no Uruguai, os caminhões começam a passar. Há uma parte do Rio Grande do Sul que não gosta. Naturalmente, eles querem vender o arroz em primeiro lugar, e eles estão certos. Pois bem, depois, sempre se consegue resolver.

Em que medida o Mercosul tem ajudado a melhorar essas relações todas?
O Mercosul não anda muito bem.

Por quê?
Porque existem diferentes visões. Às vezes há uma espécie de protecionismo para dentro em alguns países. E a tentativa de criar um espaço comum enfrenta dificuldade. Os organismos de arbitragem, de decisão, a institucionalidade real do Mercosul não funciona. Funcionam as chancelarias presidenciais. Como é o nosso caso com o Brasil. Resolvemos tudo tentando….

… diretamente com o Brasil.
Sim. Há visões que são diferentes. A Argentina tem outra visão. Tem o seu problema.

Como resolver esse impasse no Mercosul para melhorá-lo institucionalmente? Ou não é possível?
Vai ter que ser possível, porque tudo tem um limite e estamos, por exemplo, tentando negociar um acordo com a Europa. Todos precisamos disso. Por quê? Porque a presença da China na região está cada vez mais forte. E não podemos fugir disso porque é o principal comprador que temos. Se assim for, é bom ter a outra parte da balança para que nos ajude na compensação porque para ninguém é conveniente depender de um único polo econômico.

A impressão que se tem é que o Mercosul avançou muito pouco desde a sua criação. Os críticos do Mercosul dizem isso. O senhor concorda?
Sim, acho que está estagnado.

Foi uma ideia errada, na sua concepção, o Mercosul, talvez?
Acredito que os interesses empresariais nacionais são muito fortes e não priorizam a busca da integração. Vamos ver se consigo explicar. O que existe de mais forte economicamente é a burguesia paulista. Mas já não estamos na época de colonização. O papel da burguesia paulista deveria ser unir aliados, tentar construir um sistema de empresas transnacionais latino-americanas. Pelo seu tamanho, tem a responsabilidade de conduzir. Mas comete um erro se quiser fagocitar porque, em vez de ganhar aliados, ganha inimigos que se opõem à integração.

Mas, nesse caso, esperar que a burguesia paulista, como o senhor diz, tome a iniciativa de liderar o processo, não seria o caso de esperar que os políticos dos países, sobretudo do Brasil, que é o sócio mais rico do Mercosul, liderasse o processo?
O que acontece é que o mundo atravessa uma crise na política. Não é um problema do Brasil, é um problema global. A política não governa. O processo de globalização anda solto, sem governança. E aqui, as forças da economia e da política estão um pouco divorciadas. É hora de pensar a longo prazo, olhar mais longe. Eu entendo os empresários. Eles têm que se preocupar com todo fim de mês porque, senão… Mas há necessidade de ir construindo coisas complementares. Por exemplo, o Uruguai não precisa ter uma indústria automobilística, pelas suas dimensões. Mas é preciso se especializar em fazer alguma coisa, alguma autopeça que sirva para o mercado brasileiro. E assim, sucessivamente. O mesmo acontece na infraestrutura. Portugal fundou a colônia de Sacramento porque percebeu que o centro-sul do Brasil tinha que sair pelo Paraguai-Paraná. E já percebiam que para retirar carga o mais barato é transportar navegando águas abaixo. O Brasil tem que entender isso e deve ter uma política direcionada. A infraestrutura também tem que acompanhar. E essas coisas têm custo e levam tempo.

Por exemplo, há o Porto de Rocha no Uruguai, que será financiado, em parte, pelo Banco Nacional de Desenvolvimento Brasileiro. A oposição no Brasil faz críticas. Como o senhor responde a essas críticas?
Que olhem o mapa. E que voltem a olhar o mapa. Devem olhar o mapa, por favor. Não há transporte mais barato que navegar águas abaixo. Esse também tem que ser um porto brasileiro, mas também não se deve ter medo de que os outros portos vão funcionar. O desenvolvimento central do Brasil, da Bolívia, do Paraguai, exige muito mais de logística. Nós, na América, temos a síndrome de armazenador que somente quer estar no bairro onde não há concorrência.

O senhor acha que a presidente Dilma Rousseff pensa dessa forma que o senhor descreve a necessidade de integração?
Por exemplo, nós fizemos um acordo elétrico importante. Que permitirá que o sul do Brasil nos venda energia elétrica ou nós vendermos ao Brasil, dependendo das chuvas, onde esteja mais barato. Esse é o caminho certo. Temos que conectar as ferrovias. Temos que fazer muita coisa em comum. Também com a Argentina. Acredito que há um ponto-chave aqui.

Qual é?
A relação Argentina-Brasil. Eu acho que a Argentina se fecha demais. Se fecha para nós. E o Brasil tem paciência estratégica. Mas tudo tem o seu limite.

Estamos perto do limite? Estamos muito perto já desse limite que o senhor disse?
Eu não sei, mas teremos eleições nos dois lados. E pode ser que surja daí alguma variante. A Argentina é um país fundamental e é uma espécie de parceiro natural. Mas essa velha rivalidade histórica tem que ser transformada em uma aliança estratégica, e isso custa. Custa mais para Argentina do que para o Brasil.

A propósito da Argentina, a presidente Cristina Kirchner tem feito muitas críticas em relação aos credores internacionais da Argentina. O senhor concorda com as críticas que a presidente Kirchner tem feito a seus credores?
Sim, existe uma especulação financeira com uma dívida. Comprar papéis muito baratos em tempos de crise e depois pedir… é um absurdo. Provavelmente, essas coisas deveriam ter sido discutidas melhor há muito tempo.

Mas agora chegou numa situação
Agora…

…crítica.
Agora temos uma situação muito explosiva, muito pública.

Como resolver?
Terá que aguentar uns cinco ou seis meses. Se aguentar cinco ou seis meses, tudo vai se ajustar porque as obrigações legais vencem agora, no tempo devido.

Sim.
É um problema difícil. O que acontece é que somos obrigados a defender a Argentina. Por quê?

Mas houve um erro estratégico…
Porque se a Argentina entra em crise, todos vamos sentir. E, sobretudo, nós. Temos uma história: Quando a Argentinta vai bem, nós também. Quando a Argentina vai mal, nós…

Então, o apoio à posição da Argentina agora é mais estratégico do que propriamente por convicção sobre o que deve ser feito.
Sim, sim, sim.

Entendi…
É uma questão estratégica. Porque, além de precisarmos nos cuidar diante do mundo, a questão financeira não pode sepultar o econômico. O econômico deve estar acima do financeiro. Temos os papeis trocados neste mundo. E isso faz parte das contradições da época que nos tocou viver. Algumas coisas são inexplicáveis: a crise dos Estados Unidos, a crise em partes da Europa. Tudo vem do financeiro. E você tem que aprender. Temos que aprender com a realidade.

Qual foi o resultado prático da reunião da Unasul?
A de ontem?

Sim.
Do ponto de vista prático, o mais importante foi a decisão da criação do banco. É expressão de um certo grau de vontade que uma alternativa sobreviva no tempo. Mas, quando estamos negociando com a Europa, com forte resistência dentro da Europa, quando temos sérias dificuldades de consideração com os Estados Unidos, é bom que a outra parte do mundo se preocupe por nós. Para que fique mais claro. Temos uma melhor cotação internacional. E nós pensamos que não devemos depender 100% de um. Temos que ter a inteligência para estar abertos para o resto de mundo. Isso não significa vender a alma, nem vender a economia. E sim uma maneira inteligente de enfrentar a incerteza.

Agora o banco que foi anunciado pelos BRICs – Brasil, Rússia, Índia, China e África do Sul – tem duas mensagens. A primeira, é geopolítica, política. A outra, econômica-financeira, só terá efeitos no futuro. Agora, para a região aqui na América do Sul, pro Uruguai, pro Brasil, qual o efeito teria além dessa mensagem política? Ou essa, ou esse é o único efeito no momento?
Não, eu acho que é a construção de uma alternativa, de uma variável a mais. Nós não temos que brigar com o Banco Mundial, nem com o Fundo Monetário, mas, quanto mais disponibilidade tenhamos no horizonte, melhor será. Além disso, devemos pensar, estrategicamente, em formas de intercâmbio que nos permitam compensar moedas. Outra forma comercial. Parece-me que é uma necessidade do mundo vindouro. Porque nós estamos vinculados a uma moeda, o dólar, que é como medir com uma cinta métrica de borracha. Ampliam, reduzem e não temos nada a fazer. Devemos pensar em outras coisas, porque é muito contraditório. Mas essa é a realidade que vivemos.

Sobre a Unasul, la Unasur, há uma especulação sobre o senhor, depois que deixar a presidência do Uruguai, no ano que vem, passar a comandar a Unasur. O senhor tem interesse em fazer esse tipo de atividade
Eu pedi muitas vezes ao Lula, que devia ceder.

Ah, sim?
Sim…

E ele?
“Você tem que ceder.” E o Lula, que é muito astuto e inteligente, dizia-me, mais ou menos: “Olhe, Pepe, se eu for, eles vão dizer… o imperialismo brasileiro”. É, talvez. A Unasul é importante como organismo político. Mas devemos ter a inteligência para respeitar as nuances políticas que há na América. Eu, daqui, vou ao Paraguai. Provavelmente, eles têm uma maneira de pensar independente, mas eu tenho um enorme respeito pelo Paraguai. Pela Colômbia! Tenho tentado fazer tudo ao meu alcance para que a Colômbia tenha paz.

Lula fez uma sugestão ao senhor para que fosse pra Unasul depois de deixar a Presidência do Uruguai?
Como?

Lula fez uma sugestão para que o senhor fosse…
Sim, sim, ele fez sim. Lula é um ativista da integração, para unir. Ele faz tudo o que pode.

Mas, o senhor tem interesse em fazer isso no ano que vem?
O Senhor está no céu. Olhe, você sabe o que é envelhecer? É não querer sair de casa. Mas é possível que tente ajudar um pouco, por um tempo. Com muito respeito, mas estou com quase oitenta anos.

Eu ouvi que o senhor tem interesse em fazer um projeto social na sua fazenda no Uruguai, depois de deixar a presidência.
Sim, sim.

Como é esse projeto?
É uma ideia de fazer uma espécie de fazenda-escola, com trabalho de horticultura. E para aproveitar uma série de coisas que tenho. Eu sou um campesino frustrado. Eu amo a terra, eu gosto. E acredito que há muitas coisas para mostrar aos meninos, aos que virão. Tenho uma fazenda que está um pouco abandonada, mas tenho os meios. E, como comecei a consertar o mundo há muitos anos, quando era jovem, não tive filhos. É o que eu tenho e vou deixá-lo para os jovens que virão.

Voltando à geopolítica, esse grupo novo, BRICs, os países não tem muita afinidade entre si…
Nenhuma.

Qual a chance de dar tudo errado?
A afinidade é que eles têm problemas comuns. Trata-se de potências emergentes que estão procurando seu lugar sob o sol. Precisam disso. Essa é a parte que tem em comum. Depois, a China tornou-se a oficina do mundo. E os outros são os fornecedores de matérias-primas, de commodities. Mas, não nos esqueçamos disto: todos temos entrado aceleradamente em uma época diferente. Temos que começar a pensar a Terra por inteiro e temos culturas nacionais. Devemos que cuidar do planeta. Temos que tomar decisões para o mundo inteiro para defender o planeta. Essa responsabilidade, em primeiro lugar, é dos países maiores. Pensar dessa forma significa sacrificar parte da soberania para garantir a vida do planeta. Começam a surgir no horizonte problemas que não víamos, mas precisam de respostas globais. O mundo do futuro precisa de governança também. Isso não fará com que o Estado nacional desapareça. Isto significa que há problemas que nenhum país pode solucionar sozinho.

A propósito, o senhor, presidente, foi aos Estados Unidos, esteve com o presidente dos Estados Unidos, Barack Obama, e eu me recordo que houve uma conversa sobre o Uruguai receber, eventualmente, presos de Guantánamo. Como está essa oferta neste momento?
Nós dissemos que nos pareceu uma causa justa, porque sempre criticamos os Estados Unidos pela prisão de Guantánamo. Não se pode defender a democracia, o Estado de direito, e depois ter prisioneiros e juízes sem julgamento, sem tribunais. É uma contradição. Este presidente americano fez campanha e disse isso. Mas ele não é um monarca, não é um rei, é apenas um presidente. Portanto, não conseguiu.

Foi feita a oferta?
Sim, acho que tínhamos que ajudá-lo.

E como ele respondeu?
Ele depende de uma autorização do Congresso e teve muitas dificuldades.

E neste momento, está parado?
Está parado. Acho que haverá alguma decisão e o Congresso terá 30 ou 60 dias para fazer as objeções e depois…

E como funcionaria? O Uruguai receberia uma quantidade de presos de Guantánamo…
Não, quantidade não. Cinco ou seis.

Cinco ou seis.
E nós queremos que outros países da América entendam isso. Porque também devemos ajudar a Cuba. Não podemos falar todos os dias sobre direitos humanos e proferir lindos discursos e não ter compromisso.

Esses presos de Guantánamo, se fossem transferidos para o Uruguai, seriam julgados no Uruguai?
Não.

Seriam…
Seriam refugiados.

Refugiados.
Refugiados, ou seja, como homens livres. E, se quiserem ir embora, irão. Legalmente. Nós não seremos carcereiros dos Estados Unidos.

Entendi.
No Uruguai há cerca de 250 colombianos. Que vieram devido aos problemas na Colômbia. O Uruguai é um país de pessoas refugiadas que chegaram de todos os lados. Do Brasil.

Sim.
E fomos para outros lugares também.

O senhor mencionou Cuba. O senhor acredita que hoje Cuba pode ser descrita, considerada uma democracia?
Com as definições do Ocidente e da democracia representativa, não é. Com as definições marxistas e leninistas de democracia popular, certamente o é. Mas não me preocupa tanto. De qualquer forma, o que se possa negar de Cuba, ao lado da China, parece-me ridículo. E ninguém tem problemas com a China. Isto significa que criamos muito problema com Cuba porque é pequena. E, com a China, como precisamos dela, vendemos para ela e compramos dela, fazemo-nos de distraídos. Cuba tem o sonho de se tornar uma democracia sem classes sociais. Já paga um preço alto. Mas Cuba, e qualquer outro país, deve ser respeitado. E para conviver neste mundo há uma regra de ouro: aprender a respeitar aquele com o qual estamos em desacordo. O mundo é diferente. As culturas árabes, as culturas muçulmanas têm diferentes valores e pontos de vista divergentes aos nossos. Devemos respeitar, pois, caso contrário, as contradições são explosivas. A democracia tem uma grande virtude e muitos defeitos. A grande virtude é que nunca é perfeita e nem concluída. Sempre apostamos para melhorar. Aqueles que acreditam que tocaram o céu com a mão e não há mais evolução, pois bem, isso é absolutismo.

O senhor mencionou o fato de o Uruguai recebido muitos refugiados. A presidente Dilma Rousseff do Brasil relatou uma vez que, quando estava na guerrilha no Brasil, fez um treinamento na fronteira do Rio Grande do Sul com o Uruguai, mas já em território uruguaio. Isso quando ela era muito jovem. Ela já contou esse episódio para o senhor?
Não, não me contou, mas quando houve golpe de estado no Brasil.

Sim.
Militar.

64.
Eu era jovem. Muitas vezes, servi de correio para imigrantes brasileiros que estavam no Uruguai, para trazer correspondência do Rio Grande do Sul e levar. Em solidariedade aos refugiados brasileiros. Anos depois, muitos dos meus compatriotas estavam refugiados no Brasil. O Brasil foi e é o país ideal para pessoas clandestinas.

Por quê?
Porque é tão grande que as pessoas mudam de Estado e pronto, resolvido. E muitas pessoas não tinham documentos naquela época.

A presidente Dilma nunca compartilhou com o senhor as memórias desse período em que ela ficou lá próxima do Uruguai?
Não, não porque nunca temos tempo, sempre falamos sobre as urgências do Estado.

O Brasil está vivendo uma democracia já há algum tempo. Dos presidentes recentes brasileiros, Fernando Henrique, Lula e Dilma, que foram eleitos pelo voto direto, qual deles trabalhou mais pela integração do continente?
Lula.

Lula.
E Lula projetou o Brasil para fora.

Que avaliação senhor faz desse período, Fernando Henrique, Lula e agora Dilma?
Fernando Henrique, há dois Fernando Henrique. Um que foi governante e há um anterior, o pensador.

Sim.
Ele nos ajudou a pensar muito na economia, etc. Ele é uma figura importante no pensamento da América. Na verdade, todos os três, cada um de sua própria maneira, contribuíram muito. Mas devemos ter presente que Lula é um personagem que quebrou o molde. Ele tem algo muito difícil de definir, mas que o faz muito bem, que é a arte da negociação. De juntar as pessoas, aproximar os extremos, encontrar soluções para os problemas que não têm solução.

E Dilma?
Parece-me que Dilma é uma mulher muito trabalhadora, tenaz. Muito preocupada e, provavelmente, uma boa administradora.

Menos política.
Não tem a personalidade política do Lula. Talvez seja uma mulher de Estado, do funcionamento da máquina do Estado. Essa é a minha impressão. E por algum motivo foi eleita pelo Lula, por algo foi eleita.

O Brasil tem eleições este ano. O senhor tem acompanhado o processo?
Há eleições, sim.

O senhor tem um palpite, uma idéia, uma… sobre como será a eleição no Brasil? A presidente Dilma disputa mais um mandato, a reeleição.
Sim.

E, a oposição, representada pelo partido de Fernando Henrique, Sociais Democratas. O senhor acredita que, para a relação do continente, é melhor a reeleição da presidente Dilma ou uma troca, uma alternância de partidos?
Eu não acredito em qualquer cataclismo da política externa. Embora não haja reconhecimento, parece-me que a política exterior do Brasil, em termos gerais, é compartilhada. As diferenças estão em outras coisas. Uma mudança na direção do Brasil, não acredito que signifique jogar fora todo o processo de integração. Sempre tenho visto atrás do Lula, da Dilma e do Fernando Henrique, a figura do Itamaraty.

E no Uruguai, como está a sua sucessão?
Estamos em plena discussão eleitoral.

E como está o quadro?
Está igual, os números estão iguais a quando sai como candidato.

Sim?
Não sabemos se será definido no primeiro turno. E o segundo turno é muito exigente no Uruguai. Mas tenho confiança que será mantida no governo a força política com o equilíbrio justo.

Os candidatos principais são quais, no momento?
Tabaré Vázquez, que já foi presidente.

Que é o seu candidato.
Sim, um médico, Lacalle Pou, filho de um ex-presidente. Outro médico, Bordaberry, candidato pelo Partido Colorado. Acho que são os três candidatos principais. As pesquisas mostram nosso candidato com 43-44%, 30% para o Partido Nacional e cerca de 15% para o Partido Colorado. Mas, no segundo turno, a soma não é automática.

Por quê?
Porque as pessoas fazem de seu voto o que acharem melhor. Por exemplo, eu, no primeiro turno, tive cerca de 44% dos votos e, no segundo turno, tive 55-56%. Isto significa que houve pessoas de outros partidos que votaram em mim.

O senhor falou sobre uma eventual mudança de governo no Brasil: não acha que seria um cataclismo, não teríamos um problema. Como avaliar o desempenho das esquerdas, em geral, no mundo atual? Porque na Europa vemos um avanço de partidos de direita, não acha?
Sim, notório.

Como isso funciona na América Latina?
Na América Latina parece que acontece o contrário da Europa.

Exato. Por quê?
Primeiramente, tampouco é esquerda… ma non troppo. (risos)

Acredita que o Brasil é assim, por exemplo?
É uma esquerda moderada que procura que o sistema funcione e que luta para distribuir um pouco melhor.

Isto é aplicado a tudo por aqui.
Às vezes, os discursos são mais radicais, os discursos.

Mas a prática?
Veja bem, veja bem o Evo. Ele tem um discurso muito radical.

Evo Morales?
Sim. Veja a situação fiscal da Bolívia. Acredito que é a primeira vez, na história da Bolívia, que há superávit fiscal longo. Tem demonstrado ser um bom administrador e com Correa passa algo semelhante. É como se os latino-americanos tivéssemos aprendido como a dor.

Sim.
E aprendemos uma espécie de lição meio genérica que não é nem da esquerda, nem da direita. Há coisas com as quais não se brincam.

E isto é aplicável a quase tudo, certo?
Sim, com uma diferença, que é meio genérico.

E assim está o contexto da declaração quando o senhor disse que, se houver uma mudança no Brasil, não será um cataclismo porque está tudo… a política externa desenhada já…
Sim.

É assim que devo entender?
Sim, sim.

Vamos falar um pouco de futebol agora. O time de futebol do Uruguai estava indo muito bem na Copa do Mundo, mas um jogador, Luis Suárez, acabou sendo suspenso por morder um jogador da Itália, não? Como o senhor avalia essas coisas? O que aconteceu?
Esse menino tem algum problema aqui. Porque

O senhor conversou com ele?
Sim Eu fui recebê-lo.

Sim, eu vi.
Ele vem de um lar muito pobre e tem a inteligência nas canelas. É brilhante nas pernas.

Ele contou ao senhor por que mordeu?
Não, talvez tivesse vergonha. Eu acho que a raiva o enfurece e ele não se domina. Mas era o caso, na verdade, de levá-lo a um hospital. Para tratá-lo daqui, com psiquiatra. É um problema que não se soluciona com sanções. Mas eu não discuto a sanção desportiva, está bem. O que discuto são algumas coisas que não têm nada a ver com a sanção. Não pode entrar no campo, não pode estar com os colegas na concentração, quatro meses sem poder ir a uma campo de futebol, não pode ir sequer a uma cerimônia de apoio, a qualquer evento público desportivo com fins de beneficência. Por exemplo, ir a um colégio do bairro estamos loucos! Nenhum governo pode proibir que alguém entre em um campo de futebol se não tiver a assinatura de um juiz. E, vem a Fifa e “não pode entrar em um campo por quatro meses, nem na arquibancada”.

O senhor fez muitas críticas à Fifa
Ah, sim!

com palavras muito fortes.
Por isso! Por tudo isso que acabei de dizer. Não pela sanção.

Por que acha que a FIFA aplicou essa sanção ao Suárez?
Porque tem uma mentalidade de velhos que querem resolver as coisas castigando e, ao castigar, a única coisa que se gera é ódio e ressentimento. Esse menino precisa de uma ajuda aqui.

O senhor falou com ele sobre isto?
É um mundo de loucos! Porque agora pagam 100 milhões! O Barcelona vai comprá-lo por 100 milhões! Veja só, a Fifa aplica uma sanção duríssima! E o Barça paga quase 100 milhões, vai pagar 10 milhões por ano! Estamos todos loucos, estamos!

E o rapaz, o jogador, como reagiu quando o senhor falou com ele?
Ele tem que… comigo não, eu sou presidente. Ele tem que pedir perdão ao seu povo. Não tem que pedir perdão à Fifa, nem a ninguém, mas ao seu povo.

E por que
Ele era uma carta de esperança. É desses caras geniais que, de repente, não jogam durante todo o jogo, mas, de repente, entram e fazem dois gols. Como fez na Inglaterra. E, bem, vamos vê-lo com o Neymar e com o Messi, à frente do Barça. Não sei como vão fazer.

Sobre o tema da legalização da maconha, a comercialização foi adiada, não? O que aconteceu e por quê?
É necessário plantá-la e produzi-la e, do ponto de vista agrícola. As plantas não funcionam para o que nós queremos, têm o seu próprio ciclo e isso leva um tempo. Além disso, é necessário fazer estufas.

Mas, já estão em produção?
Estamos fazendo as mudas. Fazendo a reprodução vegetativa.

E, como não havia tempo, a venda então foi adiada para o ano que vem?
Sim, poderão começar a florescer em janeiro, fevereiro.

E o senhor não acha que, se não obtiver êxito na eleição do Tabaré Vázquez, e a oposição ganhar, podem mudar todo programa e anular a lei?
A oposição é meio trapaceira.

Por quê?
Porque a própria oposição apresentou um projeto no qual permite que se tenha em casa até seis plantas de maconha.

Então?
Então, se você autorizar que todo mundo tenha seis plantas de maconha, adeus.

Então o senhor não acha que mesmo com a oposição se
Eu acho que a oposição daria outra forma, tiraria do Estado. Tiraria do Estado, mas deixaria a porta aberta para o autocultivo. O que seria uma garantia, de saber de onde sai, mas não se sabe aonde vai terminar. Nos Estados Unidos, o uso está se massificando.

O senhor conversou com o Obama sobre este tema?
Não, não, não conversei. Falei com outras pessoas.

E se o Tabaré Vázquez ganhar, o programa seguirá tal como está?
Sempre haverá alguma modificação. Os programas mudam.

Há algum risco, comenta-se muito no Brasil, de que o Uruguai se converta em um país de turismo para os que querem consumir.
Não, não, não. Com o método que nós adotamos, nenhum estrangeiro pode consumir. Na realidade, o problema é ao contrário. Toda a droga que nos entra, entra pela fronteira. Vem em aviões pequenos. Todos nós sabemos que vem do coração da América. E é distribuída, e jogam pacotes

O que dizem é que a solução seria uma política conjunta de todo o continente.
Sim.

O senhor acha que esta é a saída? Porque um país tão grande como o Brasil diz que não tem condição. O que pensa?
Eu entendo, eu entendo. Já levamos quase oitenta anos reprimindo. E não conseguimos deter o avanço da droga. A via repressiva única demonstrou que é impotente em todos os lados. Como dizem, se você quer mudar, não pode continuar fazendo a mesma coisa. Tem que fazer outra coisa. Nós não afirmamos ter a solução ideal. O que dizemos é que, por ser um país pequeno, institucionalizado, com forte presença do Estado em todas partes, nós temos condição de fazer um experimento para encará-lo como enfermidade. Mas, não estamos aqui para difundir o avanço do uso de drogas. Pelo contrário, queremos identificar os consumidores para poder avisar a tempo: “Veja o que está acontecendo com você”. Se eu tomar um ou dois copos de uísque por dia, talvez até não me faça bem, mas é suportável. Agora, se eu tomar uma garrafa todos os dias, você tem que me levar para o hospital. Bom, com a droga acontece o mesmo. Se fumar um cigarro de maconha, é uma coisa. Se virar dependente, tenho que ter o indivíduo identificado porque é um caso hospitalar. Tenho que prestar auxílio. Mas, se eu o tiver no mundo clandestino, quando for prestar auxílio, desastres já aconteceram. Se multiplicaram os delitos, os roubos, já pode ter acontecido qualquer coisa.

Entendo
Essa é a questão. Mas, nós estamos preocupados com a fronteira.

RoboCup: the World Championship on robotics!

21 July 2014

www.robocup.org

RoboCup was founded in 1997 with the main goal of “developing by 2050 a Robot Soccer team capable of winning against the human team champion of the FIFA World Cup”. In the next years, RoboCup proposed several soccer platforms that have been established as standard platforms for robotics research. This domain demonstrated the capability of capturing key aspects of complex real world problems, stimulating the development of a wide range of technologies, including the design of electrical-mechanical-computational integrated techniques for autonomous robots. After more than 15 years of RoboCup, nowadays robot soccer represents only a part of the available platforms. RoboCup encompasses other leagues that, in addition to Soccer, cover Rescue (Robots and Simulation), @Home (assistive robots in home environments), Sponsored and @Work (Industrial environments), as well as RoboCupJunior leagues for young students. These domains offer a wide range of platforms for researchers with the potential to speed up the developments in the mobile robotics field.

RoboCup has already grown into a project which gets worldwide attention. Every year, multiple tournaments are organized in different countries all over the world, where teams from all over the world participate in various disciplines. There are tournaments in Germany, Portugal, China, Brazil, etc.  In 2014, RoboCup will be hosted for the 1st time in South America, in Brazil.

‘Livro da cura’ reúne conhecimento sobre plantas medicinais da tribo Huni Kuin, do Acre (O Globo)

RIO – Na entrada da oca de dez metros de altura feita de madeira e palha, uma placa tem os dizeres hanlishli kayanai. É um “espaço de cura” esse lugar erguido em pleno Parque Lage, no Jardim Botânico, Zona Sul do Rio, para abrigar uma série de eventos que começa hoje e gira em torno do lançamento de “Una Isi Kayawa — Livro da cura” (Dantes Editora), uma publicação que apresenta informações detalhadas sobre o poder medicinal de plantas usadas há gerações pelo povo indígena Huni Kuin, do Acre.

São 32 tribos com cerca de 7.500 pessoas da etnia em torno do rio Jordão. Ontem, chegaram alguns de seus representantes e integrantes do projeto. Com rostos pintados, colares de miçangas e trajes de linhas coloridas, eles se reuniram para um canto de chegada. De mãos dadas, o pajé José Matus Itsairu puxava um rito, seguido pelos demais.

— É um canto para agradecer pela nossa vinda, além de chamar as forças dos espíritos para proteger esse lugar — explicou.

Itsairu é filho do pajé Agostinho Ïka Muru, o idealizador do projeto, que morreu em 2011 ainda durante a fase de pesquisa. Ele tinha cadernos de anotações cheios de desenhos de plantas, e seu sonho, conta Itsairu, era sistematizar e difundir o conhecimento ancestral não só para seus pares, mas abri-lo à sociedade.

— Agostinho era um cientista da floresta. Ele vinha há mais de 30 anos registrando informações e tinha medo de que o saber fosse perdido — comentou o taxonomista Alexandre Quinet, que se incumbiu da difícil tarefa de fazer a ponte entre o conhecimento indígena oral e a ciência tradicional. — São lógicas diferentes, por isso o que fizemos foram transcrições literais das palestras gravadas. Até porque o livro também é para eles.

Pintura. O casal Maria e Adelino Kaxinawá se prepara para o início dos eventos. Eles estão pela primeira vez no Rio e aproveitaram para conhecer o mar, – Agência O Globo

Não à toa, os primeiros mil exemplares foram produzidos com papel feito de garrafas PET para resistir à umidade das florestas. Foram necessárias várias viagens e oficinas, além de registros fotográficos e audiovisuais. Das 351 amostras dos cadernos do pajé, 109 estão descritas no livro, com informações catalogadas por taxonomistas do Instituto de Pesquisas Jardim Botânico.

REGISTRO DA TRADIÇÃO MILENAR

Há um mês, a presidente Dilma Rousseff encaminhou ao Congresso um anteprojeto de lei obrigando empresas interessadas nos conhecimentos de povos indígenas a obter a autorização deles. Esse livro, diz Quinet, dá poder às etnias e registra oficialmente sua sabedoria.

A programação intensa se estende de hoje ao dia 27 e inclui conversas, cantos, exposição fotográfica e exibição de vídeos de Zezinho Yube, ativista indígena:

— Eles contam a história do nosso povo, que vivia em malocas, teve contato com seringueiros no início do século XX, começou a trabalhar com isso e, depois, recuperou seu território e está revitalizando sua cultura.

Até o final da estada, o grupo aproveitará para conhecer o Rio. A primeira atividade do casal Adelino e Maria Kaxinawá (outro nome dado à tribo) foi ver o mar pela primeira vez:

— Era exatamente o que imaginava: o som, o movimento. Ficamos gratos com a experiência.

Map reveals worldwide impacts of climate change (Science Daily)

Date: July 17, 2014

Source: University of Southampton

Summary: A new map, which shows the impact climate change could have on the whole planet by the end of the century if carbon emissions continue to increase, has been developed by scientists. Temperatures on the warmest days of the year are rising by 6°C or more across Europe, parts of Asia and part of North America, it shows. Also an increase in risk of flooding across 70 per cent of Asia, and the number of days of drought increasing in parts of South America, Australia and Southern Africa are illuminated by the new map.

Scientists from the University of Southampton have helped to create a new map, which shows the impact climate change could have on the whole planet by the end of the century, if carbon emissions continue to increase.

The Human Dynamics of Climate Change map, launched at the Foreign and Commonwealth Office was developed by the Met Office Hadley Centre with specific contributions from universities, Government and science organisations.

The map shows a range of potential impacts:

  • Temperatures on the warmest days of the year rising by 6°C or more across Europe, parts of Asia and part of North America
  • An increase in risk of flooding across 70 per cent of Asia
  • The number of days of drought going up by more than 20 per cent in parts of South America, Australia and Southern Africa
  • Maize yields falling by up to 12 per cent in Central America
  • Sea temperatures rising by up to 4°C in some parts of the world
  • Millions of people flooded due to sea level rise, particularly in East, Southeast and South Asia

The map illustrates how climate change could affect the global economy as regions connected by trade are affected by changes in crop yield, droughts, flooding and high temperatures. It also shows how many already water-stressed regions of the world could face an increase in the frequency and duration of droughts, at the same time as an increase in demand for water for agriculture and for the consumption of a growing population.

Professor Robert Nicholls and Dr Sally Brown, from Engineering and the Environment at the University of Southampton, contributed data and research which shows the number of people in coastal regions around the world that could potentially be flooded in the future as sea levels rise.

Dr Brown says: “We know that rising sea levels are already having profound impacts in many parts of the world. We hope that this tool will help scientists, policy makers and governments better understand the threat that climate change poses to our collective future prosperity and security and what actions are needed.”

Foreign Office Minister, Mark Simmonds said: “This map shows how the impacts of climate change on one part of the world will affect countries in other parts of the world, particularly through the global trade in food. This reinforces the point that climate change is a global problem: no country is immune, and we all need to work together to reduce the risks to our shared prosperity and security.”

Dame Julia Slingo, the Met Office Chief Scientist, said: “We’ve used the latest science to assess how potential changes in our climate will impact people around the world. This map presents that information together for the first time. While we see both positive and negative impacts, the risks vastly outweigh any potential opportunities.”

Is the universe a bubble? Let’s check: Making the multiverse hypothesis testable (Science Daily)

Date: July 17, 2014

Source: Perimeter Institute

Summary: Scientists are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never mind the Big Bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate — bubbles formed.

Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.

Never mind the big bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate — bubbles formed.

Each bubble contained another vacuum, whose energy was lower, but still not nothing. This energy drove the bubbles to expand. Inevitably, some bubbles bumped into each other. It’s possible some produced secondary bubbles. Maybe the bubbles were rare and far apart; maybe they were packed close as foam.

But here’s the thing: each of these bubbles was a universe. In this picture, our universe is one bubble in a frothy sea of bubble universes.

That’s the multiverse hypothesis in a bubbly nutshell.

It’s not a bad story. It is, as scientists say, physically motivated — not just made up, but rather arising from what we think we know about cosmic inflation.

Cosmic inflation isn’t universally accepted — most cyclical models of the universe reject the idea. Nevertheless, inflation is a leading theory of the universe’s very early development, and there is some observational evidence to support it.

Inflation holds that in the instant after the big bang, the universe expanded rapidly — so rapidly that an area of space once a nanometer square ended up more than a quarter-billion light years across in just a trillionth of a trillionth of a trillionth of a second. It’s an amazing idea, but it would explain some otherwise puzzling astrophysical observations.

Inflation is thought to have been driven by an inflation field — which is vacuum energy by another name. Once you postulate that the inflation field exists, it’s hard to avoid an “in the beginning was the vacuum” kind of story. This is where the theory of inflation becomes controversial — when it starts to postulate multiple universes.

Proponents of the multiverse theory argue that it’s the next logical step in the inflation story. Detractors argue that it is not physics, but metaphysics — that it is not science because it cannot be tested. After all, physics lives or dies by data that can be gathered and predictions that can be checked.

That’s where Perimeter Associate Faculty member Matthew Johnson comes in. Working with a small team that also includes Perimeter Faculty member Luis Lehner, Johnson is working to bring the multiverse hypothesis firmly into the realm of testable science.

“That’s what this research program is all about,” he says. “We’re trying to find out what the testable predictions of this picture would be, and then going out and looking for them.”

Specifically, Johnson has been considering the rare cases in which our bubble universe might collide with another bubble universe. He lays out the steps: “We simulate the whole universe. We start with a multiverse that has two bubbles in it, we collide the bubbles on a computer to figure out what happens, and then we stick a virtual observer in various places and ask what that observer would see from there.”

Simulating the whole universe — or more than one — seems like a tall order, but apparently that’s not so.

“Simulating the universe is easy,” says Johnson. Simulations, he explains, are not accounting for every atom, every star, or every galaxy — in fact, they account for none of them.

“We’re simulating things only on the largest scales,” he says. “All I need is gravity and the stuff that makes these bubbles up. We’re now at the point where if you have a favourite model of the multiverse, I can stick it on a computer and tell you what you should see.”

That’s a small step for a computer simulation program, but a giant leap for the field of multiverse cosmology. By producing testable predictions, the multiverse model has crossed the line between appealing story and real science.

In fact, Johnson says, the program has reached the point where it can rule out certain models of the multiverse: “We’re now able to say that some models predict something that we should be able to see, and since we don’t in fact see it, we can rule those models out.”

For instance, collisions of one bubble universe with another would leave what Johnson calls “a disk on the sky” — a circular bruise in the cosmic microwave background. That the search for such a disk has so far come up empty makes certain collision-filled models less likely.

Meanwhile, the team is at work figuring out what other kinds of evidence a bubble collision might leave behind. It’s the first time, the team writes in their paper, that anyone has produced a direct quantitative set of predictions for the observable signatures of bubble collisions. And though none of those signatures has so far been found, some of them are possible to look for.

The real significance of this work is as a proof of principle: it shows that the multiverse can be testable. In other words, if we are living in a bubble universe, we might actually be able to tell.

Did a focus on local life leave Neanderthals perilously isolated? (Image: Elisabeth Daynes/SPL)

The idea of human as networker is fast replacing the idea of human as toolmaker in the story of the human brain, claim two new books on our evolution

“HELL is other people,” goes Jean-Paul Sartre’s famous line. It is a hell that may have created us and our culture, judging by two new books. They show that the idea that we are defined by our struggles to deal with our fellow humans is shaking up archaeology and how we think about the key force driving human evolution.

The first book is Thinking Big by archaeologists Clive Gamble and John Gowlett and evolutionary psychologist Robin Dunbar. It is the story of a seven-year project – From Lucy to Language – that confronted archaeologists with the social brain hypothesis of human evolution.

The result is a dramatic demolition of the “stones and bones” approach to archaeology, which keeps researchers firmly fixed only on the physical evidence they dig up, and a move towards a grand look at the evolving human mind. There is “more to humanity than the bits of chipped bone”, write the authors as they seek a framework for all human psychological traits, from kinship and laughter to language and ceremony. Old dogma is derided as never moving beyond “WYSWTW” (What You See is What There Was).

The second book is a solo effort by Dunbar, the key thinker behind the social brain hypothesis. In Human Evolution, he lays out the big ideas that the archaeologists later took up. At its heart is the observation that as brains grew bigger, so did the groups we live in: bigger brains were built for and by social life. Modern humans have a cognitive limit of about 150 friends and family (the well-known “Dunbar’s number”). Within that circle are an average of five “intimates”, 15 best friends and 50 good friends. Chimps have an average community size of 55.

Studies of living, non-human primates show why you might need bigger brains to live in bigger groups. The more others are around, the more likely you are to be bullied out of a juicy food patch or a safe sleeping site. Such stress can be hell, especially for low-ranking females, who can be driven into infertility. To cope, primates create cliques of allies which they sustain through the pleasurable endorphin rush induced by regular mutual grooming. This solution fails if groups grow bigger, for there is not enough time for one-on-one attention. Bigger brains are key to developing smarter ways of dealing with others, the theory goes.

For Dunbar, these included laughter and singing, both great endorphin-releasers within groups. There was also fire, which gave light so evenings could be used for cooking and more “social grooming”. Then came language, together with a growing ability to read others’ intentions, which ultimately made it possible to tell stories, maintain far-flung relationships and usereligion to bind communities.

The Thinking Big archaeologists take from Dunbar the grand hypothesis that social life drives human change, switching from a view of “man the toolmaker” to “man the networker”. Alongside that, the proven relationship between brain sizeMovie Camera, group size and mental skills makes it possible to estimate the size of groups our ancestors lived in and their capacity to interact with others.

A fresh look at the Neanderthals is telling. They dominated Europe for 250,000 years, much longer than modern humans. They were skilled hunters, toolmakers and had mastered fire. Their brain size suggests they lived in groups of about 110 and had the cognitive skills to understand the feelings of others. That fits well with archaeological evidence that older and disabled Neanderthals were cared for: they perhaps knew compassion.

So why did they vanish so fast during a time of changing climate, when modern humans prospered? It may be that their mental skills were not quite adequate to maintain relationships beyond immediate group members, something we can do easily. That may have been crucial to our success: in hard times, bigger networks can mean gaining help from distant friends who are still doing well, and who you’ll help in turn. Without that “social storage” of resources, local extinction may loom. Archaeological evidence again tallies with the social brain theory: one study shows that 70 per cent of the raw materials of Neanderthal tools travelled less than 25 kilometres, while 60 per cent of those of contemporaneous humans had travelled more than 25 kilometres.

The two books fit well together but are very different. Thinking Big inspires, but much wonderful research is passed over too briefly amid general argument. An exception is a story from Beeches Pit, a 400,000-year-old site in the east of England. Archaeologists there painstakingly reassembled the flint flakes struck from a rock in the process of making a hand axe. Two flakes were found burnt bright red; they had fallen into a fire just in front of the axe-maker. We can almost see our ancestors working around what must have been a communal fire, for no one person could have gathered enough wood to keep it burning.

Dunbar’s solo work, Human Evolution, however, is a must-read. It has the great strength of showing you the inner workings of an imaginative mind, while allowing you the freedom to think, and even to disagree about whether that hellish social pressure really has given us our distinct cognitive design, along with science and the arts.

Meet Jibo, the cute social robot that knows the family (New Scientist)

14:00 16 July 2014 by Hal Hodson

It doesn’t just recognise you – it can field your phone calls and chat to you at dinner

IN SUITE 712 of the Eventi Hotel, high above the sticky June bustle of Midtown Manhattan, New York, one of the world’s most advanced consumer robots awaits command.

“Wake up, Jibo,” says Cynthia Breazeal, his creator. The robot’s round head shakes awake. He lets out a tinkling noise, then a yawn. Jibo’s two-part body twists and stretches and his face, with a single digital eye, switches on and turns to look at us. He looks like a Pixar character come to life.

Jibo is the first robot designed to be used by the whole family. He’s not a niche robot with a single purpose, like a Roomba, nor is he a toy. Available for $499 through an Indiegogo crowdfunding campaign that starts this week, Jibo is designed to tap into the social fabric of a household and help out. The first model, which will ship in 2015, will perform simple tasks like taking voice reminders, fielding phone calls and messages – connecting to the family’s phones through Wi-Fi. He will also act as the heart of the home connecting to iPads, TVs and games consoles. More complex skills include automatically identifying the faces in a room and taking pictures on request and reading a story to a child.

Breazeal chats casually to the robot: “How are you doing, Jibo?”

“I’m great, thanks for asking,” he says, cocking his head slightly as his digital eye curves into a grin. Jibo explains all the different things he can do, after a quick dance to Simon and Garfunkel’s 59th Street Bridge Song.

“I would say this is the first social, personal robot,” says Illah Nourbakhsh, a roboticist at Carnegie Mellon University in Pittsburgh. Jibo’s body language and expressions are designed to convey emotional states in the same way humans do, while his sensors and programming are tuned to our presence. Jibo knows when someone enters a room, and can identify who it is if he can see their face or hear their voice. The idea is that Jibo’s social skills help him to fit seamlessly into the household.

Jibo’s body and head movements are complex and smooth enough to convey convincing human-like body language but he cannot move around. For that, he relies on the humans in the household to pick him up – he weighs a mere 2.7 kilos – and move him from place to place. Jibo charges up via wireless pads plugged in around the house, or he can run on batteries for about 30 minutes away from a power source. When he joins the family at the dinner table, for instance.

Jibo turns to face whoever is talking, so an absent family member can use him to video chat as the rest of the family sit around the table. “With Jibo, you feel like you’re really part of the group dynamic,” says Breazeal.

“I think that’s enormous, I love it,” says Ken Goldberg, a roboticist from the University of California in Berkeley. Goldberg works on robots that can move around their environment and manipulate it, more in line with the traditional notion of the home robot. But such tasks are difficult to perfect: the dream of the robot butler is a long way off. “Right now, the most state-of-the-art robot still takes a good 20 minutes to fold a small towel,” Goldberg says.

Breazeal’s research at the MIT Media Lab, along with that of Bilge Mutlu at the University of Wisconsin-Madison, has shown how important it is for robot-human communication that robots can express emotion. “The ability to turn your head around and pay attention to something else has been taken for granted, but it’s huge,” says Mutlu.

Breazeal is also opening Jibo up to developers as a platform on which to build new kinds of apps, such as ones that let the robot place takeaway orders for “the usual” on request, or that control the lighting and heating in a home, or even keep an eye on activity patterns to make sure that senior household members are moving enough.

But socially aware robots raise new ethical questions. Would it be appropriate, for instance, for Jibo to announce that the senior family member he has been watching has fallen down and cannot get up? “We’re going to have a really interesting dilemma about when a robot can violate privacy to save a life,” Nourbakhsh says.

“The big deal with this is its optimisation for sociality,” says Nourbakhsh. “For the first time in history, we humans are going to have complex interactions with machines.”

Animals and Cultural Diplomacy (Huff Post)

Posted: 07/09/2014 4:22 pm EDT Updated: 07/09/2014 4:59 pm EDT

It was almost a decade after the Puritan government of England had executed King Charles I, and the country had begun to descend into chaos. Oliver Cromwell, who ruled as Lord Protector silenced criticism by banning newspapers, intercepting letters, and employing a network of secret police. In his History of Four-Footed Beasts, Serpents and Insects, Reverend Edward Topsell wrote, “Would it not make all men reverence a good king set over them by God, seeing the bees seek out their king if he lose himself, and by a most sagacious smelling sense, never cease till he be found out and then bear him upon their bodies if he be not able to fly. . . .” Topsell then tried to add a bit of balance by continuing, “And what king is not invited to clemency and deterred from tyranny, seeing the king of bees hath a sting but never uses the same.” We have no reason to think Topsell was a political dissident, in fact he may really have believed that he was simply recording the ways of bees. Consciously intended or not, a subtext comes through, and the English Parliament apparently agreed with it, since, two years later in 1660, it invited Charles II, son of the beheaded king, back to rule, requiring, however, that he not use his office for revenge against the regicides. Simply by speaking of animals, one participates in an ongoing process of cultural, and often political, negotiation.

J. J. Grandville, “Beehive,” 1842

The world of animals here appears parallel to that of human beings, and differences of species may stand in for those of tribe, gender, class, profession and so on. This is a sort of vision that we associate with “totemism,” which the anthropologist Claude Levi-Strauss explained in the mid-twentieth century as the application of structures initially found in the natural world, especially among animals, to human culture, as a means of representing social distinctions among indigenous peoples. Apart from the vastness of their scale and the complexity of their organization, nations are essentially tribes, and the relations between them follow many of the same dynamics. Animal symbolism is so deeply embedded in human culture that it is almost impossible to talk about animals without, simultaneously, speaking indirectly about human beings.

Levi-Strauss’ notion of totemism has been qualified, challenged and refined by subsequent thinkers, but, without trying to tease out all possible implications, it still serves as a rough working model for understanding how animals and nature may contribute to cultural diplomacy. This is apparent in the beast fables from the tradition of Aesop, a half-legendary storyteller from the Greek isle of Samos in the seventh century BCE. Several of the stories commonly attributed to him such as “The Tortoise and the Hare” or “The Fox and the Grapes” are still familiar to contemporary people from childhood. Behind the moralistic tales of talking lions and foxes, we can discern a tribal religion, with its animal totems, deities, sages and tricksters, largely deprived of their numinous qualities yet, nevertheless, in ways not terribly different from those of many indigenous peoples of Africa or the Americas.
2014-07-09-FoxGrapes_Heighway004.jpg

From very early times, the fable has been primarily, though by no means exclusively, a form associated with slaves. Aesop, Phaedrus and Babrius – the three most celebrated fabulists of the ancient world, were all slaves, as was Uncle Remus, the mouthpiece for Afro-Indian tales in the Aesopian tradition, collected by Joel Chandler Harris in the deep south of the United States just after the Civil War. The fable enabled slaves, as well as people of other social orders, to indirectly express things which might otherwise be sensitive or forbidden.

Totemism became even more overt in the High Middle Ages, with the development of heraldry. This was initially a system of emblems painted on shields to identify knights in jousts, when their faces and bodies were completely covered by armor. In the most literal way, heraldic symbols were a substitute for the human face. Heraldry was gradually extended to feudal families, and then to states, businesses, clubs and almost all other institutions. These symbols were by no means confined to animals and vegetation, but creatures such as boars, wolves, bears, lions and eagles figured very prominently. Heraldry represented identity in terms of abstract relationships among symbolic objects, which are joined in fantastic patterns with no regard for common sense. They are deliberately esoteric, pointing to the mystery which is ultimately at the core of identity.

Crest of Britain with the Lion of England and the Unicorn of Scotland

In some contexts at least, modern societies have identified with animals with constancy comparable to that of tribal peoples. These creatures need not necessarily be indigenous, wild, contemporary, or even real. England is represented by the lion, which is not indigenous, or the bulldog, which is a domestic breed. The animal representing Mauritius is the extinct dodo, while Scotland is represented by the mythical unicorn. Those are simply animals that ─ whether for historical, folkloric, commercial or geographic reasons ─ seem to embody a nation’s uniqueness. Underlying this totemic practice is an implicit analogy between the diversity of human cultures and that of all living things.

The animals in fables of the Renaissance, such as those of La Fontaine, and of political cartoons, are essentially those of heraldry. The totemic notion that animals constitute a world parallel to that of people was also responsible for the practice of physiognomy, which held that the character of a person could be read by the resemblance of his features to certain animals, so there would be wolf people, pig people, bat people and so on. That tradition, without the theoretical underpinnings, continues in caricatures and, most especially, political cartoons up through the present day, as well as in literary works such as Orwell’s Animal Farm.

One might perhaps think that the stylized animals of literary fables, heraldry and editorial cartoons are too detached from their original models for their representation to have much impact on relationships between human beings and the natural world; experience suggests otherwise. White-tailed deer, turkeys and Canada geese, though on the brink of extinction in the early twentieth century, may now be more common in the United States and Canada than they were in preColumbian times. Bald eagles, moose, beaver, buffalo, and coyotes are making significant comebacks as well. These resurgent animals are precisely those that have great iconic importance in both Amerindian and immigrant cultures. The bald eagle is the national animal of the United States, and the beaver of Canada. The turkey is an old symbol of the New World, the buffalo of the Great Plains, and moose of the far North. All of the others as well are closely identified with certain regions, landscapes or peoples.

To be sure, iconic status in human culture can often endanger animals. In the United States immediately following the Civil War, the American buffalo were deliberately hunted almost to extinction, in order to dishearten the Plains Indians, in whose lives they had a central role. In Asia today, the South China tiger is being hunted to extinction in large part because of the central role that its body parts play in folk medicine. But such events simply show another aspect of the way cultural and natural concerns are inextricably bound together.

The United States Bureau of Fish and Wildlife currently lists about 500 species as “endangered” and about another 200 as “threatened.” The many thousand additional species have been proposed for these lists. Having a local species listed can bring publicity and status as well as money for conservation, as well as less-tangible psychological satisfactions, but there is no clear criterion for either categorization. Inclusion is, therefore, a subject of continual lobbying, in which it is not always easy to tell cultural or economic motives from environmental ones.

The mediation performed by animals in human affairs is continuous, if seldom noticed, like the sound of crickets on an autumn day. In the past, this process has occasionally emerged from the background, as when Harun al Rashid gifted two leopards to Charlemagne or, in 1972, when the government of China presented a mated pair of pandas to the National Zoo in Washington, D. C. It is hard to say how much ecological awareness, if any, is reflected by either of these gifts. But the presents were at the least a reminder to the recipient that the distant land contained not only wealth and people but also natural wonders.

My broader point is that environmental problems are also cultural, in fact one cannot address one apart from the other. In general, we can say that the representation of people in terms of animals and nature, an essentially totemic tradition, can place human concerns in a broader perspective, diffusing tensions and helping us to:
• Look beyond immediate personal or collective interests;
• Comment indirectly on subjects that might otherwise be too sensitive;
• Eliminate evasive political rhetoric;
• Unite people around shared concerns such as conservation and sustainability.
Like other forms of cultural diplomacy, this may remain primarily beneath the threshold of awareness, but can be made more effective through conscious appreciation.

The borders between nations are mapped out with great precision, but boundaries among cultures are fundamentally poetic. Literary, artistic and architectural accomplishments help to distinguish human cultures from one another. Interaction with the natural world, also embodied in customs from funerals to foodways, further differentiates them from domains that are still largely beyond human understanding or control. These frontiers, in turn, are constantly in flux, a bit like wetlands that shift with the weather, season and tide. Like the elements, cultures are engaged in a perpetual negotiation. Cultural diplomacy is essentially a natural process, which requires only a hospitable environment.

Topsell was not the only person who used bees to comment on human institutions. Socrates, in Plato’s dialogue “Phaedo,” suggested that people who lived as good citizens might be reincarnated as bees. Virgil upheld the bees to his fellow Romans as models of austere living and martial valor, especially because they would sting intruders at the cost of their own lives. In the Middle Ages, people thought of the hive as a sort of monastery, but, in the early modern period, Bernard de Mandeville satirized it as an imperiled feudal state that had failed to adapt to the ways of commerce, an idea that eerily anticipates the way honey bees are dying out today. Napoleon chose bees as his emblem, because of their association with industry but also with the early medieval rulers of France. At the beginning of the twentieth century, Maurice Maeterlink stated that bees were the most intelligent animals after man, and thought of them as socialists. On learning that the so-called “king” was actually a queen, some feminists have upheld the hive as a model of matriarchal society. These various philosophies and social systems might seem to have little in common, yet they are based on essentially the same imagery.

Standard of Napoleon III

Suppose, then, that one were to hold a conference on the current dying out of bees ─ together with its agrarian, cultural, spiritual and economic implications ─ and invite representatives of groups with radically opposing social, religious and political views, from the tea party to the communists. I cannot predict what the various factions might say or what the final outcome would be, but that is precisely why such a meeting might be beneficial. You would likely to encounter some surprising coalitions and novel initiatives. All would be compelled to think beyond their accustomed rhetoric, and probably to articulate some of their core values, thus extending the mediation to other problems.

Campanha internacional criada por brasileiros chama atenção para o desaparecimento de colmeias e seu impacto sobre o ambiente e a segurança alimentar dos humanos

A notícia de que a população mundial de abelhas tem se reduzido pode até ser novidade para alguns, mas não aqui na CH On-line. Esses insetos vêm desaparecendo nos últimos 60 anos e 13 espécies foram extintas do planeta – das cerca de 20 mil existentes. O que parece uma boa notícia para os alérgicos é, no entanto, preocupante para o futuro da humanidade. Por isso, pesquisadores brasileiros lançaram uma campanha global para divulgar o sumiço de abelhas batizada de Bee or not to be? – um trocadilho em inglês com o verbo ‘ser’ (to be) e a palavra ‘abelha’ (bee) baseado na famosa frase de William Shakespeare: “Ser ou não ser, eis a questão.”

Os pesquisadores chamam a atenção para um fenômeno mundial denominado ‘síndrome do desaparecimento das abelhas’, decorrente de um problema no sistema nervoso desses insetos que faz com que eles ‘esqueçam’ o caminho de volta para sua colmeia e morram ao relento. Essa alteração está relacionada principalmente ao uso na agricultura de uma classe de pesticidas à base de nicotina, os neonicotinoides. Ao tentar polinizar os vegetais tratados com esses pesticidas, as abelhas se contaminam e desenvolvem o problema.

Cientistas pedem limite à criação de vírus mortais em laboratório (O Globo)

JC e-mail 4991, de 17 de julho de 2014

Falhas em unidades americanas elevam riscos de surtos

Um grupo multidisciplinar de cientistas de importantes universidades em diferentes países publicou ontem um alerta sobre a manipulação, em laboratórios norte-americanos, de vírus que podem se espalhar e infectar homens e outros mamíferos. A preocupação vem na esteira de seguidas notícias sobre falhas de envolvendo micro-organismos potencialmente perigosos.

“Incidentes recentes com varíola, antraz e gripe aviária em alguns dos mais importantes laboratórios dos EUA nos faz lembrar da falibilidade até das unidades mais seguras, reforçando a necessidade urgente de uma reavaliação completa de biossegurança”, escreveu o autodenominado “Grupo de Trabalho de Cambridge”, composto de pesquisadores das universidades de Harvard, Yale, Ottawa, entre outras.

No alerta, eles relatam que incidentes com patógenos têm aumentado e ocorrido em média duas vezes por semana em laboratórios privados e públicos do país. A informação é de um estudo de 2012 do periódico “Applied Biosafety”.

– Quando vemos algum caso na imprensa, dá a impressão de que são episódios raros, mas não são – comentou Amir Attaran, da Universidade de Ottawa, um dos cientistas que assinou o documento. – Estamos preocupados com as experiências perigosas que estão sendo feitas para projetar os mais infecciosos e mortais vírus da gripe e da síndrome respiratória aguda grave (Sars). Achamos que essa ciência imprudente e insensata pode ferir ou matar um grande número de pessoas. O Centro de Controle de Prevenção de Doenças, na semana passada, admitiu que laboratórios de alta segurança perderam o controle com algumas amostras.

No último caso, frascos de varíola foram encontrados por acaso num depósito inutilizado de um laboratório federal em Washington. Estima-se que eles estivessem ali há mais de 50 anos.

Attaran comparou o pronunciamento do grupo ao que cientistas fizeram em 1943, antes dos bombardeios de Hiroshima, na Segunda Guerra Mundial. E disse que o risco dessas experiências são maiores do que os possíveis benefícios dessas pesquisas, citando a recriação in vitro do vírus da gripe espanhola, de 1918, que matou 40 milhões de pessoas. Em 2006, cientistas fizeram a experiência num laboratório americano.

– Não é para ficarmos alarmados aqui – garante Volnei Garrafa, coordenador do Programa de Pós-Graduação em Bioética da UnB e membro do Comitê Internacional de Bioética da Unesco. – Mas a preocupação deles é válida, sempre há riscos, e o governo precisaria se posicionar.

LEIA O DOCUMENTO NA ÍNTEGRA:
Incidentes recentes envolvendo varíola, antraz e gripe aviária em alguns dos mais importantes laboratórios dos Estados Unidos nos faz lembrar da falibilidade até das unidades mais seguras, reforçando a necessidade urgente de uma reavaliação completa de biossegurança. Tais incidentes têm aumentado e ocorrido em média duas vezes por semana com patógenos regulados em laboratórios privados e públicos do país. Uma infecção acidental com qualquer patógeno é preocupante. Mas riscos de acidente com os recém-criados ‘patógenos potencialmente pandêmicos’ levanta novas graves preocupações.

A criação em laboratório de novas cepas de vírus perigosos e altamente transmissíveis, especialmente de gripe, mas não apenas dela, apresenta riscos substancialmente maiores. Uma infecção acidental em tal situação poderia desencadear surtos que poderiam ser difíceis ou impossíveis de controlar. Historicamente, novas cepas de gripe, uma vez que comecem a transmissão na população humana, infectaram um quarto ou mais da população mundial em dois anos.

Para qualquer experimento, os benefícios esperados deveriam superar os riscos. Experiências envolvendo a criação de patógenos potencialmente pandêmicos deveria ser limitada até que haja uma avaliação quantitativa, objetiva e confiável, dos possíveis benefícios e oportunidades de mitigação de riscos, assim como a comparação contra abordagens experimentais mais seguras.

Uma versão moderna do processo Asilomar, que define regras para pesquisas com DNA recombinante, poderia ser um ponto de partida para identificar as melhores medidas para se atingir os objetivos de saúde pública global no combate a doenças pandêmicas e assegurar os mais altos níveis de segurança. Sempre que possível, a segurança deve ser prioridade em detrimento a ações que tenham risco de pandemia acidental.

Brasil vacila em ratificar protocolo sobre biodiversidade (Greenpeace)

indigenas Brasil vacila em ratificar protocolo sobre biodiversidade

 

A demora do Congresso Nacional em votar a ratificação do Protocolo de Nagoya, assinado pelo País em 2010, pode custar a cadeira brasileira na mesa de discussões da COP-12

O Brasil foi um dos primeiros países a assinar o Protocolo de Nagoya, proposto na 10ª Conferência das Partes da Convenção das Nações Unidas sobre Biodiversidade (COP-10), em 2010, como alternativa para regulamentação do uso de recursos da biodiversidade do planeta.

Depois de quatro anos, no entanto, o País acaba de perder a chance de participar ativamente da discussão sobre o assunto. As propostas contidas no protocolo não foram ratificadas pelo Congresso Nacional. Para entrar em vigor, 50 dos 92 signatários da Convenção sobre a Diversidade Biológica (CDB) precisavam confirmar sua validade, incorporando-o a legislação, até junho deste ano. O que aconteceu nesta segunda-feira 11, sem a participação do Brasil.

“O Brasil perdeu uma grande chance deixando de votar este projeto, uma vez que o País foi protagonista da proposta, junto com o próprio Japão. Mas se em casa a gente não consegue aprovar o que sugerimos internacionalmente, isso mostra que fomos muito bons de papo e pouco eficientes na ação”, avalia Marcio Astrini, coordenador da Campanha da Amazônia do Greenpeace Brasil. “De certa maneira isso é um reflexo da visão ambiental do atual governo, que ao invés de ver no Meio Ambiente uma oportunidade, vê nele um empecilho”, completa Astrini.

Parado desde 2012 no Congresso Nacional, o projeto foi designado para uma comissão especial, que nunca foi criada. O assunto sofre forte resistência por parte da bancada ruralista, que acredita que a ratificação da proposta poderia aumentar os custos do agronegócio no Brasil.

Um dos pontos mais polêmicos refere-se ao pagamento de royalties a países pela repartição de benefícios aos detentores de conhecimentos tradicionais associado ao uso de recursos genéticos oriundos da biodiversidade, como povos indígenas e comunidades tradicionais. “O objetivo central do protocolo é aumentar a proteção sobre as reservas naturais do planeta e, para isso, deve criar uma série de regras para controlar a utilização dos recursos, estabelecendo, inclusive regras econômicas. Isso vai no caminho do que precisa ser feito no mundo todo e precisamos participar desta discussão”, observa Astrini.

O Brasil concentra aproximadamente 20% de toda a biodiversidade do planeta. A regulação contribuiria para o combate a biopirataria, com ganhos no campo da ciência e também para as populações tradicionais, que teriam seus saberes reconhecidos e valorizados.

Outro ponto importante do protocolo é o plano estratégico de preservação, que aumenta as áreas terrestres e marítimas a serem protegidas no planeta. As regiões terrestres protegidas passariam de 10% para 17% e as zonas marítimas de proteção ambiental passaria de 1% para 10% de seu total. O próximo encontro dos signatários da CDB será na 12ª Conferência das Partes (COP-12) da CDB, em Pyeongchang, República da Coréia, de 6 a 17 de outubro deste ano.

Telescópios investigam relação entre ciclo do Sol e clima (Fapesp)

Equipamentos serão sincronizados para monitorar a atividade solar de forma ininterrupta e registrar informações que podem ser associadas à variação climática (foto:divulgação)
17/07/2014

Por Diego Freire

Agência FAPESP – Pesquisadores da Universidade Estadual de Campinas (Unicamp) e da Universidade Federal Fluminense (UFF) construíram dois telescópios que vão funcionar de forma sincronizada na detecção contínua de partículas derivadas da radiação do Sol para investigar possíveis relações entre os ciclos solares e as variações climáticas da Terra.

O trabalho é resultado da pesquisa “Detecção e estudo de eventos solares transientes e variação climática”, realizada no âmbito de um acordo de cooperação entre a FAPESP e a Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro (Faperj) que tem como objetivo apoiar projetos cooperativos e intercâmbio de pesquisadores e estudantes em áreas ligadas às mudanças climáticas globais.

De acordo com o coordenador da pesquisa na Unicamp, Anderson Campos Fauth, professor associado do Instituto de Física Gleb Wataghin, já se sabe que os ciclos solares e suas flutuações apresentam alguma relação com a intensidade com que os raios cósmicos atingem a Terra, apesar de não serem considerados uma das principais causas das mudanças climáticas globais.

“Não existe um consenso sobre o mecanismo que relaciona a atividade solar e as mudanças climáticas. Há uma hipótese de que o aumento do fluxo de raios cósmicos pode estar associado ao surgimento de nuvens baixas, que globalmente exercem um efeito de resfriamento e, nas regiões polares, onde a incidência da radiação solar é baixa, têm impacto contrário, provocando aquecimento”, disse.

Fauth explica que cientistas têm observado que certos fenômenos climáticos – oceanos mais quentes, maior quantidade de chuvas tropicais, menos nuvens subtropicais, circulação mais intensa de ventos – parecem estar em parte associados ao ciclo de atividade solar, que dura em média 11 anos.

“Entretanto, esses estudos estão em fase inicial e é necessário fazer novas observações das radiações emitidas pelo Sol, principalmente quando surgem atividades como as explosões solares, e monitorar suas variações sazonais”, ponderou.

Diante disso, o trabalho da Unicamp e da UFF com os telescópios foca em um dos sinais do ciclo solar: a presença e o comportamento das partículas múons na atmosfera terrestre.

O múon é a mais abundante partícula com carga elétrica presente na superfície da Terra, representando cerca de 80% dos raios cósmicos com carga elétrica em altitudes próximas ao nível do mar. A cada segundo surgem, aproximadamente, 140 múons por metro quadrado.

O fato de a partícula quase sempre possuir trajetória retilínea facilita sua detecção com um arranjo de poucos detectores. “Essas partículas permitem estudar os eventos solares em uma região de energia que os satélites e os monitores de nêutrons posicionados na superfície terrestre não observam”, explicou Fauth.

O ano de 2014 é propício à detecção de múons pelos telescópios da Unicamp e da UFF. Ao longo deste período, o ciclo atual do Sol atinge sua máxima atividade: o número de manchas solares observadas aumenta consideravelmente e os flares – explosões que ocorrem na superfície do Sol – irrompem com grande intensidade, libertando milhões de toneladas de gás magnetizado.

Além disso, Campinas e Niterói, onde os telescópios estão instalados, têm localização privilegiada para a detecção de partículas derivadas da radiação solar, pois estão próximas à região central da Anomalia Magnética do Atlântico Sul (SAA, da sigla em inglês), onde a resistência magnética para entrada de partículas carregadas vindas do espaço é muito baixa.

A maioria dos detectores de partículas solares energéticas está instalada próximo às regiões dos polos porque, nas outras regiões, o campo magnético da Terra desvia as partículas carregadas. Mas na região da SAA há uma intensidade magnética muito inferior, uma espécie de buraco na magnetosfera que se comporta como um funil.

Muonca

O telescópio construído na Unicamp, que recebeu o nome Muonca, iniciou em abril a tomada de dados contínua, utilizando quatro detectores de partículas. Os detectores da UFF entraram em funcionamento em junho, no modo monitor – quando se realiza a contagem dos múons, sem determinar ainda sua direção de chegada.

O Muonca utiliza quatro detectores de partículas idênticos. A partícula múon, ao atravessar o cintilador do detector, produz uma luz que permite o registro de sua passagem. Um computador é utilizado no sistema de aquisição de dados, e as informações brutas são registradas em arquivos diários.

O telescópio da Unicamp foi construído em dois anos, incluindo o tempo para os processos de importação, realização dos projetos, desenhos técnicos das peças, execução por técnicos da universidade e de empresas privadas, montagem por membros do grupo de pesquisa, desenvolvimento do software de aquisição de dados e calibração dos detectores, além da programação dos códigos de análise dos dados.

O experimento opera continuamente, 24 horas por dia, e os pesquisadores desenvolvem agora um sistema que alerte por e-mail e SMS quando ocorrer algum problema ou possível evento solar na aquisição dos dados.

Recentemente, os detectores instalados em Campinas e Niterói registraram simultaneamente uma tempestade geomagnética. De acordo com Fauth, os dados estão sendo avaliados para publicação e os primeiros resultados conjuntos dos dois telescópios serão apresentados em setembro no 34º Encontro Nacional de Física de Partículas e Campos, organizado pela Sociedade Brasileira de Física em Caxambu (MG).

The fight to reform Econ 101 (Al Jazeera)

Economics is a dismal nonscience, but it need not remain that way

July 16, 2014 6:00AM ET

by 

During the last weekend of June, hundreds of students, university lecturers, professors and interested members of the public descended on the halls of University College London to attend the Rethinking Economics conference. They all shared a similar belief: that economics education in most universities had become narrow, insular and detached from the real world.

For a brief period after the financial crisis of 2008, the shortcomings of the economics profession and the way it is taught were recognized. Many economists offered up mea culpas of various kinds and conceded that since they did not foresee the biggest economic event since the Great Depression, there was probably something seriously wrong with the discipline. But as time passed and many economies began to experience gradual, somewhat muted recoveries, the profession regained its confidence.

When I was completing my master’s degree at Kingston University last year, I experienced this firsthand from the more mainstream faculty there. Lecturers offered potted explanations of the crisis using old analytical tools such as supply and demand graphs that cannot incorporate expectations to explain asset price bubbles. The same economists who, just a few years ago, told us that financial markets were the conduits of perfect information began to introduce doublethink phrases in the media such as “rational bubble” (in which investors allegedly act irrationally by bidding up asset prices in full knowledge that prices are heavily inflated but think they can bail out of the market before prices fall) to explain the events of the past few years. There is nothing rational about investors’ acting this way, because they cannot know when the bubble will burst and so cannot time their exit from the market. They cannot know when the herd movement that they are part of will come to an end, so any action that they take to ride the wave will be just as irrational as those of people unaware of the bubble. The entire exercise appeared to be an ad hoc attempt to reinterpret the facts to fit the pet theory — economic agents aware of relevant information act rationally — rather than to alter the theory in light of the facts.

It was difficult not to sense the Soviet-style revisionism that had occurred within the halls of learning: The party had tossed history down the memory hole and introduced a strange, seemingly self-contradictory language that they were busy foisting upon an unwitting public. One Chicago school economist, Ray Ball, argues that the now notorious efficient market hypothesis (EMH), which states that financial markets price in all relevant information, is actually supported by the recent crisis. He argues that the capital flight that led to the bank meltdowns lends support to the EMH because it shows how rapidly financial markets react to new information. But as many will remember, investigations clearly showed that information was not being processed efficiently by market participants in the run-up to the crisis. The most colorful example of this was the Standard & Poor’s employee who, responding to a colleague who said that they should not be rating a mortgage-backed security deal because the estimations of risk were incorrect, said that cows could be estimating the risk of a product and S&P would still rate it.

Shine a light

Despite such attempts to shore up the orthodoxy, students have sensed that something is wrong: Over the past two years, they have been organizing across more than 60 countries with the aim of forcing the vampire that is the economics profession into the light of day. While the students in the movement have a diversity of opinions on various issues, they have all come to believe that the best way to reform economics is to demand that a plurality of approaches be taught. They have rightly identified the key fault with contemporary economics teaching: the monoculture it engenders. Currently only one approach to economics is taught in the vast majority of departments in the U.S. and Europe: what is usually called neoclassical or marginalist economics, epitomized by Harvard’s Gregory Mankiw — a former chairman of the Council of Economic Advisers under President George W. Bush — and Chicago’s Gary Becker, a Nobel laureate. This is the economics of the rational, atomized individual purged of all social context, whose only goal is to maximize a mysterious, effervescent quantity called utility. In this view, the economy tends toward an equilibrium end point, at which everyone has a job and wages and profits are set in line with what each individual contributes to society.

Donald Gillies, a former president of the British Society for the Philosophy of Science, told a stunned audience that he had examined three well-known Nobel Prize–winning papers in economics and could find nothing in them that he could call scientific.

When I spoke with the students, they were struck by how even those who dissented from contemporary economic policies like austerity shared this overarching vision. Paul Krugman, for example, to whom many turned after the crisis to provide context — including many of the students I met — also accepted the orthodox view (although he has not embraced some of the worst excesses echoed by his peers).

True dissenters

The students at the June conference also said that there were true dissenters in the discipline who found that economics was a highly contested field. Cambridge University’s Ha-Joon Chang pointed out that there are any number of schools of economic thought, each with their own approaches and insights. Their opinions range from the Austrians, who believe that government interference in the economy leads to wasted resources, to post-Keynesians, who believe that capitalist economies are inherently unstable and require government intervention to stave off collapse and stagnation, to Marxians, institutionalists, Schumpeterians, neo-Ricardians and so on. Chang argued that none of these schools of thought were inherently right or wrong; they all had insights into the working of the economy, and every one of them had a right to be taught to students as a competing point of view. It was up to the students, he said, to find what they found interesting, useful and credible.

One of the conference speakers pointed out that this is required in all the other disciplines that study people and society. He told an anecdote about being in the psychology department of his university when an inspector from a psychological association turned up to ensure that there was an adequately pluralist approach being undertaken. The speaker quipped that it would be far more likely that an inspector from an economics association would turn up to ensure that the current doctrine was being firmly adhered to.

But what, exactly, constitutes this dogmatic thinking? For starters, the firm belief that economics is a science on par with physics and chemistry. After all, these economists say, only a crank would demand that a plurality of approaches to physics and chemistry should be taught in universities. But the truth of the matter is that economics is not a science on par with physics and chemistry and it never will be. Donald Gillies, a former president of the British Society for the Philosophy of Science, told a stunned audience that he had examined three well-known Nobel Prize–winning papers in economics and could find nothing in them that he could call scientific. Rather, he said, they utilized sophisticated mathematics to hide the fact that they were not saying anything remotely relevant about the real world that could be proved or disproved.

The dirty little secret about economics is that it cannot, like other sciences, undertake proper laboratory experiments. Even the experiments of the behaviorist economists are open to doubt in that it seems unlikely that the manner in which people act in a lab while under observation is identical to how they act day to day. Economics is therefore ill equipped to make claims with the same confidence as bona fide sciences. What economists offer are instead interpretations of the world around them. Once this is understood, it becomes very difficult to argue against a plurality of opinions in the discipline. This was what the students sensed, and this is why their clarion call became one for pluralism.

New curriculum

These students are well organized, and their numbers are growing; their commitment is unlikely to go away anytime soon. They are focused in a manner that is impressive for a protest movement, willing to transcend their political differences in order to fight for a common goal. Every week a new group springs up. At the conference I attended, organizers went around with pads and pens collecting the contact details of sympathetic faculty members and other students in countries where the movement was only partially developed.

Even institutions are hopping on board. Many employers complain that the mainstream departments are churning out employees with mathematical skills completely out of proportion to the jobs they do but who seem unable to undertake basic economic analysis. Often these employees have to be retrained on the job in order to function at their institutions. The chief economist of the Bank of England, Andy Haldane, wrote in the foreword to the students’ international manifesto that “employers of economists, like the Bank of England, stand to benefit from such an evolution in the economics curriculum.” Given that mainstream economists often claim that the consumer is king and competition is sacrosanct, it is increasingly difficult to see how they make a case for their current monopoly over the educational process.

In September another conference will take place in New York, and rumor has it that an enormous international meeting will soon be organized too. If and when the movement reaches that level of international organization, it could start putting real pressure on companies, governments and economics departments to rethink their models and their ways. If the profession wishes to uphold what is left of its credibility, it would do well to pay attention.

O manguezal avança (Fapesp)

01.07.2014

O manguezal da Reserva Biológica de Guaratiba, no Rio de Janeiro, parece estar em migração continente adentro. O movimento é uma resposta à elevação no nível do mar, que pesquisadores do Núcleo de Estudos do Manguezal (Nema), da Universidade do Estado do Rio de Janeiro (Uerj), atribuem a mudanças globais no clima.

O oceanógrafo Gustavo Duque Estrada, do Nema, foi a campo com a equipe de vídeo de Pesquisa FAPESP para mostrar como o grupo vem monitorando essa floresta costeira desde os anos 1990. Na universidade, o coordenador do grupo, Mário Soares, explica o significado dos resultados de pesquisa para entender os manguezais, suas respostas às mudanças ambientais e sua influência sobre o ambiente, incluindo por meio da capacidade de armazenar carbono. “Áreas que antes eram planícies hipersalinas, lá no início da década de 1990, hoje já são florestas de mangue”, conta.

Sem chuva, vale até reciclar esgoto (Página 22)

14 JULHO 2014

Na capital do oeste australiano, nem só de dessalinização vive a gestão da água. No lugar onde a seca é realidade há décadas, a reciclagem tornou-se essencial

Por Flavia Pardini na Página 22

A seca no Sudeste brasileiro pegou muita gente de calça curta no país da enxurrada. Mas no continente mais seco do mundo, a noção de que é preciso gerir a água para o futuro é realidade há décadas.

Na cidade australiana de Perth – onde a vazão para os reservatórios caiu pela metade desde os anos 1970 –, o pilar de longo prazo da política hídrica é a dessalinização, que responde por metade do consumo de 1,8 milhão de habitantes. O outro grande esforço em marcha é o de reciclar.

Um programa de tratamento de “águas residuais” – que vão pelo ralo após o uso em chuveiros, pias e máquinas de lavar – e sua reintrodução no aquífero recebeu luz verde em 2013. No início de março passado, a Water Corporation, empresa que abastece Perth, informou que 3,5 bilhões de litros de água altamente tratada e purificada foram reinjetados nos aquíferos mais profundos da região, onde ficará estocada para uso futuro. O plano é reciclar e reinjetar 7 bilhões de litros por ano, com possibilidade de expansão para 28 bilhões de litros.

O processo envolve ultrafiltragem, osmose reversa e exposição a raios ultravioleta. A reinjeção é necessária para que a população, que prefere um processo “natural” de filtragem, aceite beber água que já foi usada e descartada.

Um porta-voz da Water Corporation informou que a expectativa é de que 1 litro de água reciclada custe “um pouco menos” do que 1 litro de água dessalinizada. Ambientalistas aguerridos contestam as boas intenções da empresa – segundo eles, seria mais barato tornar obrigatório que novas residências captem água da chuva e disponham de seu próprio sistema de reciclagem.

A reciclagem, segundo a Water Corp, tem potencial para responder por até 20% do consumo de Perth em 2060.
