Why Seven African Nations Joined Anti-Monsanto Protests Last Weekend | ThinkProgress - 0 views

  • One of the company’s most compelling arguments for its quest to spread GMOs is that Monsanto products are the solution to world hunger
  • The company’s defenders claim that opposing GMOs is a luxury of Western privilege that denies developing countries vital resources to feed impoverished communities
  • According to Food Sovereignty Ghana, seven African countries held anti-Monsanto rallies on Saturday

  • “GMO will make Ghanaian farmers poor” and “Our Food Under Our Control!!!”
  • Monsanto is also part of the New Alliance for Food Security and Nutrition, a group of private corporations tasked by the G8 to invest in solutions to African hunger over the next decade.
  • Hating Monsanto is “a luxury when you’re surrounded by food 24/7,” writes one defender, who argues that spreading negative sentiment against the company actually “impedes global economic growth.” Even Britain’s Environmental Secretary, Owen Paterson, said organizations fighting the spread of GMOs are “absolutely wicked” and “cast a dark shadow over attempts to feed the world.”
  • But African farmers also have very legitimate concerns about Monsanto’s reputation for investigating, suing, and ruining farmers who try to save GM seeds.
  • ood Sovereignty Ghana warns against the “control of our resources by multinational corporations and other foreign entities,” and the “avaricious calculations behind the proposition that food is just another commodity or component for international agribusiness.”
  • they call for “collective control over our collective resources.”
  • ontroversial GM golden rice, which is supposed to pump up Vitamin A levels in regular rice to make it more nutritious, could well be a promising use of technology
  • However, golden rice is still mainly theoretical after a decade of research.
  • hunger is not caused by a food shortage but by “a lack of purchasing power and/or the inability of the rural poor to be self-sufficient.”

Science: A New Map of the Human Brain - WSJ.com - 0 views

  • The popular left/right story has no solid basis in science. The brain doesn't work one part at a time, but rather as a single interactive system, with all parts contributing in concert, as neuroscientists have long known. The left brain/right brain story may be the mother of all urban legends: It sounds good and seems to make sense—but just isn't true.
  • There is a better way to understand the functioning of the brain, based on another, ordinarily overlooked anatomical division—between its top and bottom parts. We call this approach "the theory of cognitive modes." Built on decades of unimpeachable research that has largely remained inside scientific circles, it offers a new way of viewing thought and behavior
  • Our theory has emerged from the field of neuropsychology, the study of higher cognitive functioning—thoughts, wishes, hopes, desires and all other aspects of mental life. Higher cognitive functioning is seated in the cerebral cortex, the rind-like outer layer of the brain that consists of four lobes
  • ...19 more annotations...
  • The top brain comprises the entire parietal lobe and the top (and larger) portion of the frontal lobe. The bottom comprises the smaller remainder of the frontal lobe and all of the occipital and temporal lobes.
  • research reveals that the top-brain system uses information about the surrounding environment (in combination with other sorts of information, such as emotional reactions and the need for food or drink) to figure out which goals to try to achieve. It actively formulates plans, generates expectations about what should happen when a plan is executed and then, as the plan is being carried out, compares what is happening with what was expected, adjusting the plan accordingly.
  • The bottom-brain system organizes signals from the senses, simultaneously comparing what is being perceived with all the information previously stored in memory. It then uses the results of such comparisons to classify and interpret the object or event, allowing us to confer meaning on the world.
  • The top- and bottom-brain systems always work together, just as the hemispheres always do. Our brains are not engaged in some sort of constant cerebral tug of war
  • Although the top and bottom parts of the brain are always used during all of our waking lives, people do not rely on them to an equal degree. To extend the bicycle analogy, not everyone rides a bike the same way. Some may meander, others may race.
  • You can use the top-brain system to develop simple and straightforward plans, as required by a situation—or you have the option to use it to develop detailed and complex plans (which are not imposed by a situation).
  • Our theory predicts that people fit into one of four groups, based on their typical use of the two brain systems. Depending on the degree to which a person uses the top and bottom systems in optional ways, he or she will operate in one of four cognitive modes: Mover, Perceiver, Stimulator and Adaptor.
  • Mover mode results when the top- and bottom-brain systems are both highly utilized in optional ways. Oprah Winfrey
  • Perceiver mode results when the bottom-brain system is highly utilized in optional ways but the top is not. Think of the Dalai Lama or Emily Dickinson
  • According to the theory, people who habitually rely on Mover mode are most comfortable in positions that allow them to plan, act and see the consequences of their actions. They are well suited to being leaders.
  • People who habitually rely on Perceiver mode try to make sense in depth of what they perceive; they interpret their experiences, place them in context and try to understand the implications.
  • such people—including naturalists, pastors, novelists—typically lead lives away from the limelight. Those who rely on this mode often play a crucial role in a group; they can make sense of events and provide a bigger picture
  • Stimulator mode, which results when the top-brain system is highly utilized but the bottom is not. According to our theory, people who interact with the world in Stimulator mode often create and execute complex and detailed plans (using the top-brain system) but fail to register consistently and accurately the consequences of acting on those plans
  • they may not always note when enough is enough. Their actions can be disruptive, and they may not adjust their behavior appropriately.
  • Examples of people who illustrate Stimulator mode would include Tiger Woods
  • Adaptor mode, which results when neither the top- nor the bottom-brain system is highly utilized in optional ways. People who think in this mode are not caught up in initiating plans, nor are they fully focused on classifying and interpreting what they experience. Instead, they become absorbed by local events and the immediate requirements of the situation
  • They are responsive and action-oriented and tend to "go with the flow." Others see them as free-spirited and fun to be with.
  • those who typically operate in Adaptor mode can be valuable team members. In business, they often form the backbone of an organization, carrying out essential operations.
  • No one mode is "better" than the others. Each is more or less useful in different circumstances, and each contributes something useful to a team. Our theory leads us to expect that you can work with others most productively when you are aware not just of the strengths and weakness of their preferred modes but also of the strengths and weakness of your own preferred mode

The bright side of sadness - 1 views

  • Thomas Jefferson defended the right to pursue happiness in the Declaration of Independence.
  • “Bad moods are seen in our happiness-focused culture as representing a problem, but we need to be aware that temporary, mild negative feelings have important benefits,”
  • One investigation found that people in sad moods have an advantage remembering the details of unusual incidents that they have witnessed. And a little gloominess could help job applicants; lousy moods cut down on the tendency to stereotype others, thus boosting the accuracy of first impressions.
  • ...18 more annotations...
  • Growing evidence suggests that gloomy moods improve key types of thinking and behavior, Forgas asserts in a new review paper aptly titled “Don’t worry, be sad!” For good evolutionary reasons, positive and negative moods subtly recruit thinking styles suited to either benign or troubling situations,
  • Alternatively, good moods trigger a loose mode of thought conducive to creativity and seeing the big picture. Happiness signals that a situation is safe, or at least not immediately threatening,
  • Whether good or bad, moods are relatively low-intensity, background feelings that can last for anywhere from a few minutes to the whole day. A person may feel somewhat good or bad, happy or sad, without knowing why or even being aware of such moods.
  • On “good” days, he reasoned, everything just felt right without any past triumphs coming to mind. On “bad” days, life felt lousy in the moment, without any tragic memories returning for an encore.
  • Individuals aren’t slaves to their moods, Schwarz cautions. A sad person can think outside the box if necessary, say, to solve problems at work. And a happy person can accurately fill out tax forms or complete other detail-heavy tasks.
  • Moods provide surprisingly keen insights into one’s environment, the team concluded.
  • By embracing their moods, superior forecasters gained unconscious access to a vast amount of learned information that informed their predictions, Pham speculated.
  • Many emotion theorists now agree that negative moods direct attention to tasks at hand and promote analytical thinking, whereas positive moods broaden attention and prompt original thinking. Researchers in a field dubbed “positive psychology” have put a lot of recent focus on exploring how happiness profits mind and body.
  • Sad moods also improve eyewitness memory, apparently by lowering the tendency to incorporate false and misleading details into accounts of what was observed. In a 2005 study in the Journal of Experimental Social Psychology, college students witnessed a staged altercation between a lecturer and a woman who angrily interrupted the talk.
  • Sad moods can also make first impressions of others more reliable,
  • Sad folks took longer to read and rate the essays than happy and neutral participants did. That’s probably because feeling sad fostered a more careful appraisal of essays and photos, Forgas suggests. As a result, he proposes, sad volunteers largely rejected the stereotype of philosophers as tweedy, professorial men, helping to minimize the halo effect.
  • In these experiments, moods were induced either by having participants watch happy or sad film clips or by falsely telling volunteers that they had scored extremely well or poorly on a test of spatial abilities.
  • In both conditions, raters determined that sad volunteers communicated more information relevant to the movie scenes and less unrelated information than the other two groups did, especially the happy folks. Those in a sad mood were especially good at keeping accounts brief, clear and to the point.
  • Moods were induced after participants watched movie clips but before they described the scenes, ensuring that the clips didn’t sway their manipulated moods.
  • Sad feelings may influence communication differently in situations where conversation
  • But moods may not engage specific mental strategies as proposed
  • If these findings hold up, happy and sad moods simply signal whether or not to change one’s current thinking style, Huntsinger says, rather than indicating whether to adopt an analytical or playful thinking style. Researchers have yet to test which of these two possibilities best explains mood-related behaviors.
  • much remains unknown about precisely how moods influence thought

Delay Kindergarten at Your Child's Peril - NYTimes.com - 2 views

  • THIS fall, one in 11 kindergarten-age children in the United States will not be going to class. Parents of these children often delay school entry in an attempt to give them a leg up on peers, but this strategy is likely to be counterproductive.
  • Teachers may encourage redshirting because more mature children are easier to handle in the classroom and initially produce better test scores than their younger classmates.
  • This advantage fades by the end of elementary school, though, and disadvantages start to accumulate. In high school, redshirted children are less motivated and perform less well. By adulthood, they are no better off in wages or educational attainment — in fa

  • The benefits of being younger are even greater for those who skip a grade, an option available to many high-achieving children. Compared with nonskippers of similar talent and motivation, these youngsters pursue advanced degrees and enter professional school more often. Acceleration is a powerful intervention, with effects on achievement that are twice as large as programs for the gifted.
  • Parents who want to give their young children an academic advantage have a powerful tool: school itself. In a large-scale study at 26 Canadian elementary schools, first graders who were young for their year made considerably more progress in reading and math than kindergartners who were old for their year
  • school makes children smarter.
  • The question we should ask instead is: What approach gives children the greatest opportunity to learn?
  • These differences may come from the increased challenges of a demanding environment. Learning is maximized not by getting all the answers right, but by making errors and correcting them quickly.
  • Some children, especially boys, are slow to mature emotionally, a process that may be aided by the presence of older children.
  • The benefits of interacting with older children may extend to empathetic abilities. Empathy requires the ability to reason about the beliefs of others. This capacity relies on brain maturation, but it is also influenced by interactions with other children. Having an older (but not younger) sibling speeds the onset of this capacity in 3- to 5-year-olds. The acceleration is large: up to half a year per sibling.
  • children are not on a fixed trajectory but learn actively from teachers — and classmates. It matters very much who a child’s peers are. Redshirted children begin school with others who are a little further behind them. Because learning is social, the real winners in that situation are their classmates.
  •  
    I had never realized how incredibly critical the first years of a child's life were. This situation seems almost like a win-lose one; the younger children are more challenged and thus more prepared later on in life while the older ones will always be less motivated and all-around strong. Does this mean that we must set up our classrooms to have some students be statistically advantaged in life while others might potentially suffer? ARE WE GONNA DO THAT?!

Triumph of the Unthinking - NYTimes.com - 0 views

  • “Words,” wrote John Maynard Keynes, “ought to be a little wild, for they are the assault of thoughts on the unthinking.”
  • It’s true that in practice Mr. Obama pushed through a stimulus that, while too small and short-lived, helped diminish the depth and duration of the slump. But when Republicans began talking nonsense, declaring that the government should match the belt-tightening of ordinary families — a recipe for full-on depression — Mr. Obama didn’t challenge their position. Instead, within a few months the very same nonsense became a standard line in his speeches, even though his economists knew better, and so did he.
  • Like Mr. Obama and company, Labour’s leaders probably know better, but have decided that it’s too hard to overcome the easy appeal of bad economics, especially when most of the British news media report this bad economics as truth.
  • ...5 more annotations...
  • What nonsense am I talking about? Simon Wren-Lewis of the University of Oxford, who has been a tireless but lonely crusader for economic sense, calls it “mediamacro.” It’s a story about Britain that runs like this: First, the Labour government that ruled Britain until 2010 was wildly irresponsible, spending far beyond its means. Second, this fiscal profligacy caused the economic crisis of 2008-2009. Third, this in turn left the coalition that took power in 2010 with no choice except to impose austerity policies despite the depressed state of the economy. Finally, Britain’s return to economic growth in 2013 vindicated austerity and proved its critics wrong.
  • every piece of this story is demonstrably, ludicrously wrong
  • Yet this nonsense narrative completely dominates news reporting, where it is treated as a fact rather than a hypothesis. And Labour hasn’t tried to push back, probably because they considered this a political fight they couldn’t win. But why?
  • Mr. Wren-Lewis suggests that it has a lot to do with the power of misleading analogies between governments and households, and also with the malign influence of economists working for the financial industry, who in Britain as in America constantly peddle scare stories about deficits and pay no price for being consistently wrong. If U.S. experience is any guide, my guess is that Britain also suffers from the desire of public figures to sound serious, a pose which they associate with stern talk about the need to make hard choices (at other people’s expense, of course.)
  • The fact is that Britain and America didn’t need to make hard choices in the aftermath of crisis. What they needed, instead, was hard thinking — a willingness to understand that this was a special environment, that the usual rules don’t apply in a persistently depressed economy, one in which government borrowing doesn’t compete with private investment and costs next to nothing.

Santorum Wants The Pope To Back Off Talking About Climate Science | ThinkProgress - 0 views

  • On June 16, Pope Francis is expected to release an encyclical letter on the environment, the Catholic Church’s strongest statement to date on the moral issues associated with climate change. It’s a move that has environmentalists very excited — and one GOP presidential nominee less than thrilled.
  • “When we get involved with controversial and scientific theories, I think the Church is not as forceful and not as credible,” Santorum continued. “I’ve said this to the Catholic bishops many times — when they get involved in agriculture policy, or things like that, that are really outside of the scope of what the Church’s main message is, that we’re better off sticking to the things that are really the core teachings of the Church as opposed to getting involved in every other kind of issue that happens to be popular at the time.”
  • By releasing an encyclical on climate change, the Catholic Church isn’t involving itself in controversial science — it’s reiterating what a majority of scientists already know: that the climate is changing, and that humans are the cause.

Yes, Religious Conservatives Accept Climate Change - Just Not The Ones You Think | Thin... - 0 views

  • Mooney uses two studies to argue that conservative religious belief can trigger climate change denial — namely, a chart created by Josh Rosenau of the National Center for Science Education and new study conducted by David Konisky and Matthew Arbuckle of Georgetown and the University of Cincinnati, respectively.
  • Although the exact definition of “conservative religious beliefs” is actively debated among religion scholars, these attributes fall squarely under Mooney’s own definition of church-going conservatives.
  • Perhaps most importantly for lawmakers, the survey also found that majorities of all major American religious groups — including 82 percent of Jewish Americans, 76 percent of black Protestants, and 69 percent of Hispanic Catholics — agreed that dealing with climate change now will help prevent future economic problems.

How Scientists Engage the Public | Pew Research Center - 0 views

  • American scientists believe they face a challenging environment and the vast majority of them support the idea that participation in policy debates and engagement with citizens and journalists is necessary to further their work and careers.
  • A survey of 3,748 American-based scientists connected with the American Association for the Advancement of Science (AAAS) finds that 87% agree with the statement “Scientists should take an active role in public policy debates about issues related to science and technology.”
  • These findings come at a time when science topics are increasingly part of the public debate. Pew Research findings from this survey reported last month showed an overall drop among AAAS scientists in how they rate the state of science in general and their particular scientific field. Scientists also express concerns about the precarious state of research funding, some of the influences on how funding is allocated, and difficulties they feel hinder the capacity of science disciplines to attract the best talent to the field.
  • ...2 more annotations...
  • Nearly all the AAAS scientists (98%) say they have some level of interaction with citizens at least from time to time, and 51% have at least some contact with reporters about research findings. In addition, nearly half of AAAS scientists – 47% – use social media to talk about science or read about scientific developments at least some of the time.
  • The scientists who are most likely to be involved in public activities show distinct patterns by age, by the level of public debate and public interest they perceive in their specialty, and by discipline. Virtually all scientists engage with citizens. Mid-career and older scientists are especially likely to speak to reporters. Younger scientists are more likely to use social media. And blogging is something that equally spans the generations under age 65.

Scientists See How Brain Areas Communicate - 1 views

  • Carnegie Mellon Univ. neuroscientists have identified a new pathway by which several brain areas communicate within the brain's striatum.
  • the findings illustrate structural and functional connections that allow the brain to use reinforcement learning to make spatial decisions, such as the dorsolateral prefrontal (DLPFC), orbitofrontal cortex (OFC) and posterior parietal cortex (PPC).

  • ...5 more annotations...
  • The hope is that more knowledge of how the connectivity is related to behavior will help scientists develop therapeutic interventions that focus on strengthening potentially weakened or damaged pathways.
  • They found that the pathways from all three areas projected to similar areas within a forebrain region called striatum, a part of the basal ganglia pathways that are most commonly associated with Parkinson's disease. The patterns were consistent across all participants
  • The results showed that the convergence zones were not only structurally connected but functionally connected as well. More importantly, the areas at the surface of the brain in all three cortical areas showed a high overlap of structure and functional connectivity
  • there may be a structural and functional network in the brain that allows us to integrate information about where we are focusing our attention in our visuospatial environment with reward and punishment signals associated with our past action choices in order to learn how to update and, hopefully improve, our future action decisions,

The Science of Why We Don't Believe Science | Mother Jones - 2 views

  • an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.
  • The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself.
  • reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.

  • Consider a person who has heard about a scientific discovery that deeply challenges her belief in divine creation—a new hominid, say, that confirms our evolutionary origins. What happens next, explains political scientist Charles Taber of Stony Brook University, is a subconscious negative response to the new information—and that response, in turn, guides the type of memories and associations formed in the conscious mind. "They retrieve thoughts that are consistent with their previous beliefs," says Taber, "and that will lead them to build an argument and challenge what they're hearing."
  • In other words, when we think we're reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we're being scientists, but we're actually being lawyers
  • Our "reasoning" is a means to a predetermined end—winning our "case"—and is shot through with biases. They include "confirmation bias," in which we give greater heed to evidence and arguments that bolster our beliefs, and "disconfirmation bias," in which we expend disproportionate energy trying to debunk or refute views and arguments that we find uncongenial.

Rise in Scientific Journal Retractions Prompts Calls for Reform - NYTimes.com - 1 views

  • before long they reached a troubling conclusion: not only that retractions were rising at an alarming rate, but that retractions were just a manifestation of a much more profound problem — “a symptom of a dysfunctional scientific climate,” as Dr. Fang put it.

  • science has changed in some worrying ways in recent decades — especially biomedical research, which consumes a larger and larger share of government science spending.
  • the journal Nature reported that published retractions had increased tenfold over the past decade, while the number of published papers had increased by just 44 percent.
  • because journals are now online, bad papers are simply reaching a wider audience, making it more likely that errors will be spotted.
  • The National Institutes of Health accepts a much lower percentage of grant applications today than in earlier decades. At the same time, many universities expect scientists to draw an increasing part of their salaries from grants, and these pressures have influenced how scientists are promoted.
  • Dr. Fang and Dr. Casadevall looked at the rate of retractions in 17 journals from 2001 to 2010 and compared it with the journals’ “impact factor,” a score based on how often their papers are cited by scientists. The higher a journal’s impact factor, the two editors found, the higher its retraction rate.
  • Each year, every laboratory produces a new crop of Ph.D.’s, who must compete for a small number of jobs, and the competition is getting fiercer. In 1973, more than half of biologists had a tenure-track job within six years of getting a Ph.D. By 2006 the figure was down to 15 percent.

  • “What people do is they count papers, and they look at the prestige of the journal in which the research is published, and they see how may grant dollars scientists have, and if they don’t have funding, they don’t get promoted,” Dr. Fang said. “It’s not about the quality of the research.”
  • Dr. Ness likens scientists today to small-business owners, rather than people trying to satisfy their curiosity about how the world works. “You’re marketing and selling to other scientists,” she said. “To the degree you can market and sell your products better, you’re creating the revenue stream to fund your enterprise.”
  • Universities want to attract successful scientists, and so they have erected a glut of science buildings, Dr. Stephan said. Some universities have gone into debt, betting that the flow of grant money will eventually pay off the loans.
  • “You can’t afford to fail, to have your hypothesis disproven,” Dr. Fang said. “It’s a small minority of scientists who engage in frank misconduct. It’s a much more insidious thing that you feel compelled to put the best face on everything.”
  • , Dr. Stephan points out that a number of countries — including China, South Korea and Turkey — now offer cash rewards to scientists who get papers into high-profile journals.
  • To change the system, Dr. Fang and Dr. Casadevall say, start by giving graduate students a better understanding of science’s ground rules — what Dr. Casadevall calls “the science of how you know what you know.”
  • They would also move away from the winner-take-all system, in which grants are concentrated among a small fraction of scientists. One way to do that may be to put a cap on the grants any one lab can receive.
  • Such a shift would require scientists to surrender some of their most cherished practices — the priority rule, for example, which gives all the credit for a scientific discovery to whoever publishes results first.
  • To ease such cutthroat competition, the two editors would also change the rules for scientific prizes and would have universities take collaboration into account when they decide on promotions.
  • Even scientists who are sympathetic to the idea of fundamental change are skeptical that it will happen any time soon. “I don’t think they have much chance of changing what they’re talking about,” said Dr. Korn, of Harvard.
  • “When our generation goes away, where is the new generation going to be?” he asked. “All the scientists I know are so anxious about their funding that they don’t make inspiring role models. I heard it from my own kids, who went into art and music respectively. They said, ‘You know, we see you, and you don’t look very happy.’ ”

  • “It makes a hostile environment for me,” she said. “But I don’t want to raise my hand and call negative attention toward myself, and become the woman who is the problem — ‘that woman.’ In start-up culture they protect their own tribe, so by putting my hand up, I’m saying I’m an ‘other,’ I shouldn’t be there, so for me that’s an economic threat.”
  • “Many women have come to me and said they basically have had to hide on the Net now,” said Mr. Weinstein, who works on issues of identity and anonymity online. “They use male names, they don’t put their real photos up, because they are immediately targeted and harassed.”
  • “It’s a boys’ club, and you have to try to get into it, and they’re trying as hard as they can to prove you can’t,” said Ephrat Bitton, the director of algorithms at FutureAdvisor, an online investment start-up that she says has a better culture because almost half the engineers are women.
  • Writing code is a high-pressure job with little room for error, as are many jobs. But coding can be stressful in a different way, women interviewed for this article said, because code reviews — peer reviews to spot mistakes in software — can quickly devolve.
  • “Code reviews are brutal — ‘Mine is better than yours, I see flaws in yours’ — and they should be, for the creation of good software,” said Ellen Ullman, a software engineer and author. “I think when you add a drop of women into it, it just exacerbates the problem, because here’s a kind of foreigner.”
  • But some women argue that these kinds of initiatives are unhelpful.“My general issue with the coverage of women in tech is that women in the technology press are talked about in the context of being women, and men are talked about in the context of being in technology,” said a technical woman who would speak only on condition of anonymity because she did not want to be part of an article about women in tech.

Schoolroom Climate Change Indoctrination - WSJ - 0 views

  • While many American parents are angry about the Common Core educational standards and related student assessments in math and English, less attention is being paid to the federally driven green Common Core that is now being rolled out across the country. Under the guise of the first new K-12 science curriculum to be introduced in 15 years, the real goal seems to be to expose students to politically correct climate-change orthodoxy during their formative learning years.
  • The standards were designed to provide students with an internationally benchmarked science education.
  • From the council’s perspective, the science of climate change has already been settled. Not surprisingly, global climate change is one of the disciplinary core ideas embedded in the Next Generation of Science Standards, making it required learning for students in grade, middle and high school.
  • ...3 more annotations...
  • The National Research Council framework for K-12 science education recommends that by the end of Grade 5, students should appreciate that rising average global temperatures will affect the lives of all humans and other organisms on the planet. By Grade 8, students should understand that the release of greenhouse gases from burning fossil fuels is a major factor in global warming. And by Grade 12, students should know that global climate models are very effective in modeling, predicting and managing the current and future impact of climate change.
  • Relying on a climate-change curriculum and teaching materials largely sourced from federal agencies—particularly those of the current ideologically driven administration—raises a number of issues. Along with the undue authoritative weight that such government-produced documents carry in the classroom, most of the work is one-sided and presented in categorical terms, leaving no room for a balanced discussion. Moreover, too much blind trust is placed in the predictive power of long-range computer simulations, despite the weak forecasting track record of most climate models to date.
  • Employing such a Socratic approach to teaching climate change would likely lead to a rational and thought-provoking classroom debate on the merits of the case. However, that is not the point of this academic exercise—which seems to be to indoctrinate young people by using K-12 educators to establish the same positive political feedback loop around global warming that has existed between the federal government and the nation’s colleges and universities for the past two decades.

Smarter Every Year? Mystery of the Rising IQs - WSJ - 0 views

  • That’s because absolute performance on IQ tests—the actual number of questions people get right—has greatly improved over the last 100 years. It’s called the Flynn effect, after James Flynn, a social scientist at New Zealand’s University of Otago who first noticed it in the 1980s.
  • They found that the Flynn effect is real—and large. The absolute scores consistently improved for children and adults, for developed and developing countries. People scored about three points more every decade, so the average score is 30 points higher than it was 100 years ago.
  • The pace jumped in the 1920s and slowed down during World War II. The scores shot up again in the postwar boom and then slowed down again in the ’70s. They’re still rising, but even more slowly. Adult scores climbed more than children’s.
  • ...5 more annotations...
  • Genes couldn’t change that swiftly, but better nutrition and health probably played a role. Still, that can’t explain why the change affected adults’ scores more than children’s. Economic prosperity helped, too—IQ increases correlate significantly with higher gross domestic product.
  • The fact that more people go to school for longer likely played the most important role—more education also correlates with IQ increases. That could explain why adults, who have more schooling, benefited most.
  • The best explanation probably depends on some combination of factors. Dr. Flynn himself argues for a “social multiplier” theory. An initially small change can set off a benign circle that leads to big effects. Slightly better education, health, income or nutrition might make a child do better at school and appreciate learning more. That would motivate her to read more books and try to go to college, which would make her even smarter and more eager for education, and so on.
  • “Life history” is another promising theory. A longer period of childhood correlates with better learning abilities across many species.
  • The thing that really makes humans so smart, throughout our history, may be that we can invent new kinds of intelligence to suit our changing environments.

The 50 Greatest Breakthroughs Since the Wheel - James Fallows - The Atlantic - 0 views

  • Some questions you ask because you want the right answer. Others are valuable because no answer is right; the payoff comes from the range of attempts.
  • That is the diversity of views about the types of historical breakthroughs that matter, with a striking consensus on whether the long trail of innovation recorded here is now nearing its end.
  • The clearest example of consensus was the first item on the final compilation, the printing press
  • ...27 more annotations...
  • Leslie Berlin, a historian of business at Stanford, organized her nominations not as an overall list but grouped into functional categories.
  • Innovations that expand the human intellect and its creative, expressive, and even moral possibilities.
  • Innovations that are integral to the physical and operating infrastructure of the modern world
  • Innovations that enabled the Industrial Revolution and its successive waves of expanded material output
  • Innovations extending life, to use Leslie Berlin’s term
  • Innovations that allowed real-time communication beyond the range of a single human voice
  • Innovations in the physical movement of people and goods.
  • Organizational breakthroughs that provide the software for people working and living together in increasingly efficient and modern ways
  • Finally, and less prominently than we might have found in 1950 or 1920—and less prominently than I initially expected—we have innovations in killing,
  • Any collection of 50 breakthroughs must exclude 50,000 more.
  • We learn, finally, why technology breeds optimism, which may be the most significant part of this exercise.
  • Popular culture often lionizes the stars of discovery and invention
  • For our era, the major problems that technology has helped cause, and that faster innovation may or may not correct, are environmental, demographic, and socioeconomic.
  • people who have thought deeply about innovation’s sources and effects, like our panelists, were aware of the harm it has done along with the good.
  • “Does innovation raise the wealth of the planet? I believe it does,” John Doerr, who has helped launch Google, Amazon, and other giants of today’s technology, said. “But technology left to its own devices widens rather than narrows the gap between the rich and the poor.”
  • Are today’s statesmen an improvement over those of our grandparents’ era? Today’s level of public debate? Music, architecture, literature, the fine arts—these and other manifestations of world culture continually change, without necessarily improving. Tolstoy and Dostoyevsky, versus whoever is the best-selling author in Moscow right now?
  • The argument that a slowdown might happen, and that it would be harmful if it did, takes three main forms.
  • Some societies have closed themselves off and stopped inventing altogether:
  • By failing to move forward, they inevitably moved backward relative to their rivals and to the environmental and economic threats they faced. If the social and intellectual climate for innovation sours, what has happened before can happen again.
  • visible slowdown in the pace of solutions that technology offers to fundamental problems.
  • a slowdown in, say, crop yields or travel time is part of a general pattern of what economists call diminishing marginal returns. The easy improvements are, quite naturally, the first to be made; whatever comes later is slower and harder.
  • America’s history as a nation happens to coincide with a rare moment in technological history now nearing its end. “There was virtually no economic growth before 1750,” he writes in a recent paper.
  • “We can be concerned about the last 1 percent of an environment for innovation, but that is because we take everything else for granted,” Leslie Berlin told me.
  • This reduction in cost, he says, means that the next decade should be a time of “amazing advances in understanding the genetic basis of disease, with especially powerful implications for cancer.”
  • the very concept of an end to innovation defied everything they understood about human inquiry. “If you look just at the 20th century, the odds against there being any improvement in living standards are enormous,”
  • “Two catastrophic world wars, the Cold War, the Depression, the rise of totalitarianism—it’s been one disaster after another, a sequence that could have been enough to sink us back into barbarism. And yet this past half century has been the fastest-ever time of technological growth. I see no reason why that should be slowing down.”
  • “I am a technological evolutionist,” he said. “I view the universe as a phase-space of things that are possible, and we’re doing a random walk among them. Eventually we are going to fill the space of everything that is possible.”

As Interest Fades in the Humanities, Colleges Worry - NYTimes.com - 0 views

  • “Both inside the humanities and outside, people feel that the intellectual firepower in the universities is in the sciences, that the important issues that people of all sorts care about, like inequality and climate change, are being addressed not in the English departments,”
  • nationally, the percentage of humanities majors hovers around 7 percent — half the 14 percent share in 1970. As others quickly pointed out, that decline occurred between 1970, the high point, and 1985, not in recent years.
  • “In the scholarly world, cognitive sciences has everybody’s ear right now, and everybody is thinking about how to relate to it,” said Louis Menand, a Harvard history professor. “How many people do you know who’ve read a book by an English professor in the past year? But everybody’s reading science books.”

  • while it is easy to spot the winners at science fairs and robotics competitions, students who excel in humanities get less acclaim and are harder to identify.
  • “I got the sense from them that it’s not cool to be a nerd in high school, unless you’re a STEM nerd,” he said, using the term for science, technology, engineering and mathematics.
  • “I live in Seattle, surrounded by Amazon and Google and Microsoft,” said Ms. Roberts, a history buff. “One of the best things about the program, that made us all breathe a sigh of relief, was being in an environment where no one said: “Oh, you’re interested in humanities? You’ll never get a job.”
  • since the recession — probably because of the recession — there has been a profound shift toward viewing college education as a vocational training ground. “College is increasingly being defined narrowly as job preparation, not as something designed to educate the whole person,”
  • Many do not understand that the study of humanities offers skills that will help them sort out values, conflicting issues and fundamental philosophical questions, said Leon Botstein, the president of Bard College. “We have failed to make the case that those skills are as essential to engineers and scientists and businessmen as to philosophy professors,” he said.

BBC News - Light shed on how genes shape face - 0 views

  • Working on mice, researchers have identified thousands of small regions of DNA that influence the way facial features develop.
  • The findings, published in Science, could also help researchers to learn how facial birth defects arise.
  • "Somewhere in there there must be that blueprint that defines what our face looks like."
  • ...7 more annotations...
  • The international team has found more than 4,000 "enhancers" in the mouse genome that appear to play a role in facial appearance.
  • "In the mouse embryos we can see where exactly, as the face develops, this switch turns on the gene that it controls.
  • "These mice looked pretty normal, but it is really hard for humans to see differences in the face of mice," explained Prof Visel.
  • "What this really tells us is that this particular switch also plays a role in development of the skull and can affect what exactly the skull looks like," he explained.
  • Understanding this could also help to reveal why and how things can go wrong as embryos develop in the womb, leading to facial birth defects.
  • "And they have severe implications for the kids that are affected. They affect feeding, speech, breathing, they can require extensive surgery and they have psychological implications."
  • Professor Visel added that scientists were just at the beginning of understanding the processes that shape the face, but their early results suggested it was an extremely complex process.

BBC News - New galaxy 'most distant' yet discovered - 0 views

  • The galaxy is about 30 billion light-years away and is helping scientists shed light on the period that immediately followed the Big Bang.
  • "This is the most distant galaxy we've confirmed. We are seeing this galaxy as it was 700 million years after the Big Bang."
  • Astronomers were able to measure how far it was from Earth by analysing its colour.
  • ...5 more annotations...
  • The system is small: about 1-2% the mass of the Milky Way and is rich in heavier elements.
  • astronomers are likely to discover even more distant galaxies when Nasa's James Webb Space Telescope (JWST) is launched and other ground-based telescopes come online.
  • One very interesting way to learn about the Universe is to study these outliers and that tells us something about what sort of physical processes are dominating galaxy formation and galaxy evolution. "What was great about this galaxy is not only is it so distant, it is also pretty exceptional."
  • But it has a surprising feature: it is turning gas and dust into new stars at a remarkable rate, churning them out hundreds of times faster than our own galaxy can.
  • This is an important step forward, but we need to continue looking for more.
