"People tend to conform their factual beliefs to ones that are consistent with their cultural outlook, their world view," Braman says. The Cultural Cognition Project has conducted several experiments to back that up. Participants in these experiments are asked to describe their cultural beliefs. Some embrace new technology, authority and free enterprise. They are labeled the "individualistic" group. Others are suspicious of authority or of commerce and industry. Braman calls them "communitarians." In one experiment, Braman queried these subjects about something unfamiliar to them: nanotechnology — new research into tiny, molecule-sized objects that could lead to novel products. "These two groups start to polarize as soon as you start to describe some of the potential benefits and harms," Braman says. The individualists tended to like nanotechnology. The communitarians generally viewed it as dangerous. Both groups made their decisions based on the same information. "It doesn't matter whether you show them negative or positive information, they reject the information that is contrary to what they would like to believe, and they glom onto the positive information," Braman says.

"Basically the reason that people react in a close-minded way to information is that the implications of it threaten their values," says Dan Kahan, a law professor at Yale University and a member of The Cultural Cognition Project. Kahan says people test new information against their preexisting view of how the world should work. "If the implication, the outcome, can affirm your values, you think about it in a much more open-minded way," he says. And if the information doesn't, you tend to reject it. In another experiment, people read a United Nations study about the dangers of global warming. Then the researchers told the participants that the solution to global warming is to regulate industrial pollution. Many in the individualistic group then rejected the climate science. But when more nuclear power was offered as the solution, says Braman, "they said, you know, it turns out global warming is a serious problem."And for the communitarians, climate danger seemed less serious if the only solution was more nuclear power.

King's comments weren't recorded, but a staffer for Media Matters, who heard the comments, provided TPMmuckraker with an account. The staffer, who requested anonymity because she's not a communications specialist, said that King, an extreme right-winger with a reputation for eyebrow-raising rhetoric, appeared as a surprise guest speaker on an immigration panel at the conservative conference. During his closing remarks, King veered into a complaint about high taxes, and said he could "empathize" with the man who flew a plane into an IRS building last week. During the question and answer session, the Media Matters staffer asked King to clarify his comment, reminding him of his sworn duty to protect the American people from all sworn enemies, foreign and domestic. In response, said the staffer, King gave a long and convoluted answer about having been personally audited by the IRS, and ended by saying he intended to hold a fundraiser to help people "implode" their local IRS office.

Joe Stack's adult daughter, Samantha Bell, spoke to ABC's "Good Morning America" from her home in Norway. Asked during a phone interview broadcast Monday if she considered her father a hero, she said: "Yes. Because now maybe people will listen." Authorities say Stack, 53, targeted the IRS office building in Austin on Thursday, killing employee Vernon Hunter and himself, after posting a ranting manifesto against the agency and the government. He apparently set fire to his home before flying his plane into the office building. Hunter's son, Ken Hunter, said he's alarmed by comments that the pilot was a hero. "How can you call someone a hero who after he burns down his house, he gets into his plane ... and flies it into a building to kill people?" Hunter told ABC." "My dad Vernon did two tours of duty in Vietnam. My dad's a hero." Bell said she offered her deepest condolences to Hunter's family. She said her father's last actions were wrong. "But if nobody comes out and speaks up on behalf of injustice, then nothing will ever be accomplished," she told ABC. "But I do not agree with his last action with what he did. But I do agree about the government,"

During the debate over unemployment benefits, Senator Jeff Merkley, a Democrat of Oregon, made a plea for action on behalf of those in need. In response, Mr. Bunning blurted out an expletive. That was undignified — but not that different, in substance, from the position of leading Republicans.Consider, in particular, the position that Mr. Kyl has taken on a proposed bill that would extend unemployment benefits and health insurance subsidies for the jobless for the rest of the year. Republicans will block that bill, said Mr. Kyl, unless they get a “path forward fairly soon” on the estate tax. Now, the House has already passed a bill that, by exempting the assets of couples up to $7 million, would leave 99.75 percent of estates tax-free. But that doesn’t seem to be enough for Mr. Kyl; he’s willing to hold up desperately needed aid to the unemployed on behalf of the remaining 0.25 percent. That’s a very clear statement of priorities.So, as I said, the parties now live in different universes, both intellectually and morally. We can ask how that happened; there, too, the parties live in different worlds. Republicans would say that it’s because Democrats have moved sharply left: a Republican National Committee fund-raising plan acquired by Politico suggests motivating donors by promising to “save the country from trending toward socialism.” I’d say that it’s because Republicans have moved hard to the right, furiously rejecting ideas they used to support. Indeed, the Obama health care plan strongly resembles past G.O.P. plans. But again, I don’t live in their universe. More important, however, what are the implications of this total divergence in views?The answer, of course, is that bipartisanship is now a foolish dream. How can the parties agree on policy when they have utterly different visions of how the economy works, when one party feels for the unemployed, while the other weeps over affluent victims of the “death tax”?Which brings us to the central political issue right now: health care reform. If Congress enacts reform in the next few weeks — and the odds are growing that it will — it will do so without any Republican votes. Some people will decry this, insisting that President Obama should have tried harder to gain bipartisan support. But that isn’t going to happen, on health care or anything else, for years to come.Someday, somehow, we as a nation will once again find ourselves living on the same planet. But for now, we aren’t. And that’s just the way it is.

Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

Statistical validation of results, as Shaffer described it, simply involves testing the null hypothesis: that the pattern you detect in your data occurs at random. If you can reject the null hypothesis—and science and medicine have settled on rejecting it when there's only a five percent or less chance that it occurred at random—then you accept that your actual finding is significant. The problem now is that we're rapidly expanding our ability to do tests. Various speakers pointed to data sources as diverse as gene expression chips and the Sloan Digital Sky Survey, which provide tens of thousands of individual data points to analyze. At the same time, the growth of computing power has meant that we can ask many questions of these large data sets at once, and each one of these tests increases the prospects than an error will occur in a study; as Shaffer put it, "every decision increases your error prospects." She pointed out that dividing data into subgroups, which can often identify susceptible subpopulations, is also a decision, and increases the chances of a spurious error. Smaller populations are also more prone to random associations. In the end, Young noted, by the time you reach 61 tests, there's a 95 percent chance that you'll get a significant result at random. And, let's face it—researchers want to see a significant result, so there's a strong, unintentional bias towards trying different tests until something pops out. Young went on to describe a study, published in JAMA, that was a multiple testing train wreck: exposures to 275 chemicals were considered, 32 health outcomes were tracked, and 10 demographic variables were used as controls. That was about 8,800 different tests, and as many as 9 million ways of looking at the data once the demographics were considered.

Bloomberg.com has reported that the Obama administration is planning to launch an official complaint against China with the World Trade Organisation (WTO) pertaining to the country's stringent web censorship policies. Illinois Senator Richard Durbin has announced that he plans to pass a legislation that will allow the government to prosecute US internet companies if they violate the human rights of their customers when a foreign government asks them to do so. 

No silver bullets. This is the simple premise of Diane Ravitch’s new book, “The Death and Life of the Great American School System,” which is being brought out this week by Basic Books. Written by one of our nation’s most respected scholars, it has been eagerly awaited. But it has also been, at least in some quarters, anticipated with a certain foreboding, because it was likely to debunk much of the conventional — and some not so conventional — wisdom surrounding education reform.

What of the once-great comprehensive high schools, institutions with history and in some cases a track record of success going back generations? As time moves on, it is fast becoming clear that the new small schools, many with inane themes (how about the School of Peace and Diversity?), can never substitute for a good neighborhood high school, which can become a center of communal life and pride. Ms. Ravitch’s report underscores the fact that the trick is to fix the neighborhood schools beset with problems, not destroy them.

It is not only the foundations that Ms. Ravitch blames for the current crisis: government has also failed in the attempt to reform the schools from above, lacking a clear perspective of how schools work on a day-to-day basis. Thus, the major federal initiative, No Child Left Behind, well intentioned as it may have been, ended up damaging the quality of education, not improving it. While the federal government declares schools as “failing” and prescribes sanctions for schools not meeting its goal of “annual yearly progress,” it is the states that are allowed to write and administer the tests. This has led to a culture of ever easier tests and more test preparation rather than real instruction. More ominously, it led to such scandals as the New York State Education Department lowering the “cut scores” that define the line between passing and failing. Ms. Ravitch suggests that the proper roles of the states and federal government have been reversed under NCLB. Maybe the standards for achievement should be set in Washington, which, after all, administers the National Assessment of Educational Progress , and the solutions found at the local level, using the accurate data provided by Washington. Instead of moving in a different direction from the failed NCLB model of the Bush Administration, the Obama administration has adopted and expanded on them.
