Pop Warner Football Limits Contact in Practices - NYTimes.com - 0 views

  • In response to growing concerns over head injuries in football, Pop Warner, the nation’s largest youth football organization, announced rule changes on Wednesday that will limit the amount of full-speed collisions and other contact allowed in practice.
  • The issue of brain injuries sustained on the football field has forced a reckoning at all levels of the sport in recent years. Pop Warner’s new rules, which will affect hundreds of thousands of youth football players, some as young as 5 years old, were seen as the latest acknowledgment that the nation’s most popular sport poses dangers to the long-term cognitive health of its athletes.
  • Under its new rules, effective for the coming season, which starts in August, contact will not be allowed for two-thirds of each practice — a move prompted by research showing that most of the hardest hits in youth football occur not in games, but in practice. The organization is also forbidding all drills that involve full-speed, head-on blocking and tackling that begins with players lined up more than three yards apart, as well as head-to-head contact.

  • The group was persuaded to take its more drastic step when a study of second-grade football players published in February — which used data from sensors installed in helmets — showed that the average player sustained more than 100 head impacts during the course of about 10 practices and 5 games. Though most of those hits were moderate, some exceeded a force equivalent to a big hit in college football.

Two Worlds Cracking Up - NYTimes.com - 0 views

  • It turns out that Turkey these days is neither a bridge nor a gully. It’s an island — an island of relative stability between two great geopolitical systems that are cracking apart: the euro zone that came into being after the cold war, and the Arab state system that came into being after World War I are both coming unglued
  • The island of Turkey has become one of the best places to observe both these worlds. To the east, you see the European Monetary Union buckling under the weight of its own hubris — leaders who reached too far in forging a common currency without the common governance to sustain it. And, to the south, you see the Arab League crumbling under the weight of its own decay — leaders who never reached at all for the decent governance and modern education required to thrive in the age of globalization.
  • The Syrians failed to build Syria, the Egyptians failed to build Egypt, the Libyans failed to build Libya, the Yemenis failed to build Yemen. Those are even bigger problems because, as their states have been stressed or fractured, no one knows how they’ll be put back together again.

  • Europeans failed to build Europe, and that is now a big problem because, as its common currency comes under pressure and the E.U. goes deeper into recession, the whole world feels the effects
  • In Europe, the supranational project did not work, and now, to a degree, Europe is falling back into individual states.
  • In the Arab world, the national project did not work, so some of the Arab states are falling back onto sects, tribes, regions and clans.

Essay-Grading Software, as Teacher's Aide - Digital Domain - NYTimes.com - 0 views

  • AS a professor and a parent, I have long dreamed of finding a software program that helps every student learn to write well. It would serve as a kind of tireless instructor, flagging grammatical, punctuation or word-use problems, but also showing the way to greater concision and clarity.
  • The standardized tests administered by the states at the end of the school year typically have an essay-writing component, requiring the hiring of humans to grade them one by one.
  • the Hewlett Foundation sponsored a study of automated essay-scoring engines now offered by commercial vendors. The researchers found that these produced scores effectively identical to those of human graders.

  • humans are not necessarily ideal graders: they provide an average of only three minutes of attention per essa
  • We are talking here about providing a very rough kind of measurement, the assignment of a single summary score on, say, a seventh grader’s essay
  • “A few years back, almost all states evaluated writing at multiple grade levels, requiring students to actually write,” says Mark D. Shermis, dean of the college of education at the University of Akron in Ohio. “But a few, citing cost considerations, have either switched back to multiple-choice format to evaluate or have dropped writing evaluation altogether.”
  • As statistical models for automated essay scoring are refined, Professor Shermis says, the current $2 or $3 cost of grading each one with humans could be virtually eliminated, at least theoretically.
  • the cost of commercial essay-grading software is now $10 to $20 a student per year. But as the technology improves and the costs drop, he expects that it will be incorporated into the word processing software that all students use
  • As essay-scoring software becomes more sophisticated, it could be put to classroom use for any type of writing assignment throughout the school year, not just in an end-of-year assessment. Instead of the teacher filling the essay with the markings that flag problems, the software could do so. The software could also effortlessly supply full explanations and practice exercises that address the problems — and grade those, too.
  • “Providing students with instant feedback about grammar, punctuation, word choice and sentence structure will lead to more writing assignments,” Mr. Vander Ark says, “and allow teachers to focus on higher-order skills.”
  • When sophisticated essay-evaluation software is built into word processing software, Mr. Vander Ark predicts “an order-of-magnitude increase in the amount of writing across the curriculum.”
  • the essay-scoring software that he and his teammates developed uses relatively small data sets and ordinary PCs — so the additional infrastructure cost for schools could be nil.
  • the William and Flora Hewlett Foundation sponsored a competition to see how well algorithms submitted by professional data scientists and amateur statistics wizards could predict the scores assigned by human graders. The winners were announced last month — and the predictive algorithms were eerily accurate.
  • wanted to create a neutral and fair platform to assess the various claims of the vendors. It turns out the claims are not hype.”

Business - Derek Thompson - How Americans Lost Two Decades of Wealth, in 1 Graph - The ... - 0 views

  • The typical American family's net worth plunged by 40 percent between 2007 and 2010, from $126,400 to $77,300, wiping out two decades of gains and thrusting the typical family's wealth back to 1992 levels.
  • median household wealth popped in the bubble and collapsed in the bust, as housing prices fell by 30 to 40 percent in the worst-hit metros, in California, Nevada, and Florida. In 2007, barely half of families surveyed by the Federal Reserve reported savings. Just as the boom made families feel richer, the financial shock made families feel poorer. And so falling housing prices led to falling wealth, which led to falling spending, which led to falling private sector revenue, which led to massive job cuts, which dragged down housing prices even further, and around and around we go.
  • this is why stimulus-supporters support stimulus. A nation that controls its currency and has low borrowing costs has not only an obligation but also an easy opportunity to step into the vicious cycle and erect a firewall -- either with (a) massive spending, (b) tax cuts, (c) lower interest rates, (d) higher inflation expectations, or (e) all of the above

The World as We Know It Is About to End, Say Some Really Frightened Scientists - Global... - 0 views

  • A new study by 22 biologists and ecologists has found that environmental changes on our planet are reaching a point of no return that leads to mass extinctions and harms human welfare. The situation, said one scientist, “scares the hell out of me.”
  • How soon do these scientists expect the world as we know it to end? Gillis writes, "within a few human generations, if not sooner." The most frightening thing is that this finding isn't about what will come if we do not act, but that our effects on the planet's environment -- global warming, population growth, and overall resource extraction -- means that we've already passed a "tipping point." This isn't a plea for change. These are things scientists have been warning us about for decades.

Politics - Jonathan Merritt - The Religious Right Turns 33: What Have We Learned? - The... - 0 views

  • As we look back on more than a quarter century of political engagement by the religious right, two things now appear obvious.
  • First, partisan religion is killing American Christianity. The American church is declining by nearly every data point. Christians are exerting less influence over the culture than even a few years ago, organized religion no longer garners the respect of the masses, and two in three young non-Christians claim they perceive the Christian church as "too political." Church attendance is declining, and the percentage of Americans claiming no religious affiliation is rising.
  • The question we must now answer is not, "Can we save this nation?" but "Can we save our faith?" And the only way it seems we will be able to do the latter is through abandoning the partisan, divisive strategies adopted by the Christian right and begin engaging the public

International - Dorian Jones - Evolution Comes Under Fire in Turkey's Higher Education ... - 0 views

  • Critics believe that Turkey's governing Justice and Development Party (AKP), which has Islamist roots, was the real organizational force behind the meeting. Earlier this year, in defense of provisions for classes on the Islamic prophet Mohammed, Prime Minister Recep Tayyip Erdoğan declared that "all children will be brought up as good Muslims.
  • Defenders of evolution have long complained that, during its decade-long rule, the (AKP) government has increasingly downplayed evolution theories in textbooks at the expense of creationist explanations. Officially, teachers are supposed to teach both concepts, but they are given great latitude in their classrooms.
  • "The reason for having this symposium in a university is an attempt on their part to create a perception that being against evolution is supported and acknowledged by universities and the scientific world," charged Suat Bozkurt, director of Egitim Sen's Istanbul branch. The ministry downplayed such claims, saying that Turkish public schools explore all ideas. Cankocak, the physics professor, disputed official assertions, countering that many incoming university students are unfamiliar with evolutionary concepts. "My students did not learn evolution in high schools, so, therefore, in my university 90 out of 100 [students] don't believe or don't know evolution," he complained. "But it's worse in other universities."

  • government support for creationism began after the 1980 military coup d'état, when Turkey's ruling generals vigorously encouraged Islamic beliefs as a counterweight to left-wing political ideas that enjoyed a wide following in Turkey at the time. Along with purging many teachers for liberal or leftist political sympathies, the policy introduced creationism into school textbooks and compulsory religious education.

Who Should Teach Our Children? - NYTimes.com - 0 views

  • college teachers do a good job because of qualities that they already have when they complete their undergraduate education: a high level of intelligence, enthusiasm for ideas and an ability to communicate. In this regard, they are like those who go into other knowledge-based professions
  • Moreover, as in other knowledge-based professions, college faculties can be trusted to do their jobs well with minimal external supervision, assessment and in-service training
  • These reflections lead me to a simple proposal. Adopt the same model for grade school and high school teaching that works for colleges. Currently, few of the best students from the best colleges are grade school or high school teachers. (The most encouraging data merely suggest that high school teachers may be a bit above average, while grade school teachers are considerably below average)

  • Top doctoral programs have far more applicants than they can accept, and many excellent students don’t apply, either because they do not have a high enough level of specialized skills or because they do not want to risk the terrible job market for college teachers. Such students would form a natural pool for non-college teaching
  • There are also many excellent students with no interest in the advanced research that is the focus of doctoral programs who would prefer non-college teaching to less intellectually engaging and less socially useful work
  • So why not make use of all this talent to develop an elite class of professionals — like those who teach in our colleges — and give them primary responsibility for K-12 education?
  • Moreover, it’s important that teachers be — as they now often are not — credible authority figures, a status readily supported by the justified self-confidence and prestige of an elite professional.
  • , the greatest intellectual challenge of teaching at any level is to find ways of presenting the content effectively. Our current system seems often to assume that K-12 teachers will need the guidance of “experts” to tell them how to do this. There’s considerable doubt as to the existence of the alleged expertise.
  • Attracting an elite professional class of K-12 teachers requires more than just higher salaries. We also have to eliminate the oversize classes, lack of discipline and inane bureaucracy that can take the joy out of teaching and will drive away the best college graduates. Can we afford all this? The first response is that we need to overcome our self-destructive aversion to raising taxes to pay for what we desperately need

NFL Concussions Mega-Lawsuit Claims League Hid Brain Injury Links From Players - 0 views

  • NEW YORK — Scores of lawsuits involving thousands of former players touched by concussions and brain injuries have been consolidated into one master complaint, setting up a massive and potentially costly case for the NFL.
  • "The NFL, like the sport of boxing, was aware of the health risks associated with repetitive blows producing sub-concussive and concussive results and the fact that some members of the NFL player population were at significant risk of developing long-term brain damage and cognitive decline as a result," the complaint charges. "Despite its knowledge and controlling role in governing player conduct on and off the field, the NFL turned a blind eye to the risk and failed to warn and/or impose safety regulations governing this well-recognized health and safety problem."

Tests of Parents Are Used to Map Genes of a Fetus - NYTimes.com - 0 views

  • researchers have determined virtually the entire genome of a fetus using only a blood sample from the pregnant woman and a saliva specimen from the father
  • That would allow thousands of genetic diseases to be detected prenatally. But the ability to know so much about an unborn child is likely to raise serious ethical considerations as well. It could increase abortions for reasons that have little to do with medical issues and more to do with parental preferences for traits in children.
  • The process is not practical, affordable or accurate enough for use now, experts said. The University of Washington researchers estimated that it would cost $20,000 to $50,000 to do one fetal genome today. But the cost of DNA sequencing is falling at a blistering pace, and accuracy is improving as well. The researchers estimated that the procedure could be widely available in three to five years. Others said it would take somewhat longer.

Kohr Principles - NYTimes.com - 0 views

  • Geographical size not only influences how countries view themselves; it also determines how they interact. The wrong mix of sizes can be disastrous for international equilibrium. One could argue, for example, that this was a factor in both world wars. Or as Henry Kissinger succinctly put it: “Poor old Germany. Too big for Europe, too small for the world.”
  • Leopold Kohr, a 20th-century Austrian academic whose work inspired both modern political anarchism and the Green movement.
  • “The Breakdown of Nations.” Published first in Britain, in 1957, the book develops his theory of the optimal size of polities: “There seems to be only one cause behind all forms of social misery: bigness.” Size was the root of all evil: “Whenever something is wrong, it is too big.”
  • ...9 more annotations...
  • Kohr’s guiding principle was anarchism, “the noblest of philosophies.” But its inherent nobility, he recognized, also made it utopian:
  • Kohr cleverly turned this utopianism upside down, from weakness to strength: any party, any leader, any ideology promising utopia is automatically wrong, or lying [7]. Acceptance of utopia’s unattainability, in other words, is the best insurance against totalitarianism.
  • The strength of the American federation, Kohr thought, rested in no small part on the genius of its division: into states of roughly equal size. How different American history could have coursed, if the Union had looked like this:
  • Kohr supported the independence movements of Puerto Rico, Wales and Anguilla [8], and opposed grand unification projects like the European Union. He appealed for the breakup of Czechoslovakia and Yugoslavia, long before they happened
  • : “The absolute maximum to which a society can expand without having its basic functions degrade, is about 12 to 15 million people.”
  • One of his 10 basic laws is the so-called Beanstalk Principle: For every animal, object, institution or system, there is an optimal limit beyond which it ought not to grow. In other words: “too big to fail” is a contradiction in terms. The real solution is to make countries (and companies) too small to fai
  • in Kohr’s vision, smaller government should mean, first and foremost, a smaller area to govern.
  • In 1992, Freddy Heineken — yes, he of beer-brewing fame — devised Eurotopia, a Europe divided into 75 regions, based on Kohr’s ideas. And much earlier, revolutionary France produced a proposal for geometrically identical départements [12] prefiguring Kohr’s Europe map.
  • Some other Kohr principles: the Law of Peripheral Neglect (governmental concern, like marital fidelity or gravitational pull, diminishes with the square of distance); the Population Principle (as the size of a population doubles, its complexity quadruples); and the Self-Reliance Principle (self-reliant communities are less likely to get involved in war than those who depend on global trade systems).

More Bad News Piles Up for Facebook - Business - The Atlantic Wire - 0 views

  • nearly half of the respondents now have less favorable opinion of Facebook than they used to simply because the IPO has been such a disappointment. Even thought the declining share price and frustrating technical troubles had zero affect on most Americans (or even the average investor) simply giving off the impression of a bumbling, unpopular company can change the customer's perception of it
  • Part of the reason the stock is struggling is because the public offering has exposed some of the cracks in the armor of Facebook's business model. Ads are awkward and under-performing and revenue is not growing at the rate it once was, particularly when matched against the site gigantic user base. (The site makes a little over a dollar per user, each quarter.) That makes consumers less interested in the site, which depresses the ad market even more, which drives down share prices, which turns off consumers... and so on. The stock opens on Tuesday at $26.90, still well below its IPO price of $38.

Bloomberg Backs Plan to Limit Arrests for Marijuana - NYTimes.com - 0 views

  • The New York Police Department, the mayor and the city’s top prosecutors on Monday endorsed a proposal to decriminalize the open possession of small amounts of marijuana, giving an unexpected lift to an effort by Gov. Andrew M. Cuomo to cut down on the number of people arrested as a result of police stops.
  • Mayor Michael R. Bloomberg, whose Police Department made about 50,000 arrests last year for low-level marijuana possession, said the governor’s proposal “strikes the right balance” in part because it would still allow the police to arrest people who smoke marijuana in public.
  • The governor’s announcement was cheered by lawmakers from minority neighborhoods as well as by civil rights groups, who are increasingly looking to Albany and to Washington in an effort to rein in what they see as overly aggressive tactics on the part of the Bloomberg administration.

  • The one thing that these five schools have in common is that they are full of children from the nation’s wealthiest families.

  • Texas has 15 of the 100 best, placing second over all nationwide, while Florida has 10, the fourth most. This is no doubt due in good part to the reform efforts of George W. and Jeb Bush, who — like Newsweek — have made standardized test results a true measure of academic excellence.
  • Of the nation’s 26,000 high schools, about 2,000 sent data, and of those, 1,000 were named to the list, meaning any school with a little gumption has a 50 percent chance of being a best.
  • My concern is that the lists are stacked. Schools with the greatest challenges can appear to be the biggest failures. At a time when public education is so data-driven, that kind of thinking can cost dedicated teachers and principals their jobs.

This Republican Economy - NYTimes.com - 0 views

  • What do I mean by saying that this is already a Republican economy? Look first at total government spending — federal, state and local. Adjusted for population growth and inflation, such spending has recently been falling at a rate not seen since the demobilization that followed the Korean War.
  • Isn’t Mr. Obama a big spender? Actually, no; there was a brief burst of spending in late 2009 and early 2010 as the stimulus kicked in, but that boost is long behind us. Since then it has been all downhill. Cash-strapped state and local governments have laid off teachers, firefighters and police officers; meanwhile, unemployment benefits have been trailing off even though unemployment remains extremely high.
  • In President Obama’s case, much though not all of the responsibility for the policy wrong turn lies with a completely obstructionist Republican majority in the House. That same obstructionist House majority effectively blackmailed the president into continuing all the Bush tax cuts for the wealthy, so that federal taxes as a share of G.D.P. are near historic lows — much lower, in particular, than at any point during Ronald Reagan’s presidency.

Well, U.S. borrowing costs have just hit a record low. And remember those dire warnings about inflation and the “debasement” of the dollar? Well, inflation remains low, and the dollar has been stronger than it was in the Bush years.
  • Republicans have been warning that we were about to turn into Greece because President Obama was doing too much to boost the economy; Keynesian economists like myself warned that we were, on the contrary, at risk of turning into Japan because he was doing too little. And Japanification it is, except with a level of misery the Japanese never had to endure.
  • the Obama team has consistently failed to highlight Republican obstruction, perhaps out of a fear of seeming weak. Instead, the president’s advisers keep turning to happy talk, seizing on a few months’ good economic news as proof that their policies are working — and then ending up looking foolish when the numbers turn down again. Remarkably, they’ve made this mistake three times in a row: in 2010, 2011 and now once again.

Cyberweapon Warning From Kaspersky, a Computer Security Expert - NYTimes.com - 0 views
