The Importance of Doing Recent History | History News Network - 1 views

  • We argue that writing contemporary history is different from the role historians might play as public intellectuals who draw on their expertise to comment on recent events in the media. Instead, the writing of recent history shifts the boundaries of what might be considered a legitimate topic of historical study. The very definition of “history” has hinged on the sense of a break between past and present that allows for critical perspective. The historians’ traditional task has been to bring a “dead,” absent past back into the present. However, those doing recent history recognize that their subject matter is not fully past, or as Renee Romano puts it in our edited collection about recent history, it’s “not dead yet.”
  • studying the recent past presents real methodological challenges. It untethers the academic historian from the aspects of our practice that give us all, regardless of field or political bent, a sense of common enterprise: objectivity, perspective, a defined archive, and a secondary literature that is there to be argued with, corrected and leaned upon.

No Sign of Methane on Mars; Abstract Thought Melts Political Convictions - Technology -... - 0 views

  • There's a great Louis C.K. routine in which he describes getting flustered by his daughter's incessant question—"why?—to everything he says. "You don't even know who the fuck you are at the end of the conversation," he joked. That's basically what psychologists at the University of Illinois discovered in their research on political convictions. They found that if you just ask a highly partisan person "why" three times, hoping to clarify their stances, they tend to drift into politically moderate territory. "We used the ground zero mosque as a particularly polarizing issue," says University of Illinois professor Jesse Preston. "People feel strongly about it generally one way or the other." But they felt much less strongly about the proposed mosque near grounds zero when asked why they held such strong beliefs three times.
  • We observed that liberals and conservatives became more moderate in their attitudes. After this very brief task that just put them in this abstract mindset, they were more willing to consider the point of view of the opposition." [University of Illinois at Urbana Champaig

A New Kind of Tutoring Aims to Make Students Smarter - NYTimes.com - 1 views

  • the goal is to improve cognitive skills. LearningRx is one of a growing number of such commercial services — some online, others offered by psychologists. Unlike traditional tutoring services that seek to help students master a subject, brain training purports to enhance comprehension and the ability to analyze and mentally manipulate concepts, images, sounds and instructions. In a word, it seeks to make students smarter.

Everyone Should Write - The Dish | By Andrew Sullivan - The Daily Beast - 0 views

  • You should write because when you know that you’re going to write, it changes the way you live
  • the difference between you and a zoologist or you and a botanist is that the botanist, when she looks at a flower, has a question in mind. She’s trying to generate questions. For her the flower is the locus of many mental threads, some nascent, some spanning her career. Her field notebook is not some convenient way to store lifeless data to be presented in lifeless papers so that other scientists can replicate some dull experiment; it’s the site of a collision between a mind and a world.
  • When I have a piece of writing in mind, what I have, in fact, is a mental bucket: an attractor for and generator of thought. It’s like a thematic gravity well, a magnet for what would otherwise be a mess of iron filings. I’ll read books differently and listen differently in conversations. In particular I’ll remember everything better; everything will mean more to me

Nate Silver, Artist of Uncertainty - 0 views

  • In 2008, Nate Silver correctly predicted the results of all 35 Senate races and the presidential results in 49 out of 50 states. Since then, his website, fivethirtyeight.com (now central to The New York Times’s political coverage), has become an essential source of rigorous, objective analysis of voter surveys to predict the Electoral College outcome of presidential campaigns. 
  • Political junkies, activists, strategists, and journalists will gain a deeper and more sobering sense of Silver’s methods in The Signal and the Noise: Why So Many Predictions Fail—But Some Don’t (Penguin Press). A brilliant analysis of forecasting in finance, geology, politics, sports, weather, and other domains, Silver’s book is also an original fusion of cognitive psychology and modern statistical theory.
  • Its most important message is that the first step toward improving our predictions is learning how to live with uncertainty.

  • he blends the best of modern statistical analysis with research on cognition biases pioneered by Princeton psychologist and Nobel laureate in economics  Daniel Kahneman and the late Stanford psychologist Amos Tversky. 
  • Silver’s background in sports and poker turns out to be invaluable. Successful analysts in gambling and sports are different from fans and partisans—far more aware that “sure things” are likely to be illusions,
  • The second step is starting to understand why it is that big data, super computers, and mathematical sophistication haven’t made us better at separating signals (information with true predictive value) from noise (misleading information). 
  • One of the biggest problems we have in separating signal from noise is that when we look too hard for certainty that isn’t there, we often end up attracted to noise, either because it is more prominent or because it confirms what we would like to believe.
  • In discipline after discipline, Silver shows in his book that when you look at even the best single forecast, the average of all independent forecasts is 15 to 20 percent more accurate. 
  • Silver has taken the next major step: constantly incorporating both state polls and national polls into Bayesian models that also incorporate economic data.
  • Silver explains why we will be misled if we only consider significance tests—i.e., statements that the margin of error for the results is, for example, plus or minus four points, meaning there is one chance in 20 that the percentages reported are off by more than four. Calculations like these assume the only source of error is sampling error—the irreducible error—while ignoring errors attributable to house effects, like the proportion of cell-phone users, one of the complex set of assumptions every pollster must make about who will actually vote. In other words, such an approach ignores context in order to avoid having to justify and defend judgments.

Hollywood Seeks to Slow Cultural Shift to TV - NYTimes.com - 0 views

  • a steady push toward viewing on phones and tablets is shrinking the spirit of films. In the past, he said — citing “A Man for All Seasons,” “8 ½,” and “The Searchers” — there was a grandeur to films that delivered long-form storytelling on very large screens.
  • the prospect that a film will embed itself into the cultural and historical consciousness of the American public in the way of “Gone With the Wind” or the “Godfather” series seems greatly diminished in an era when content is consumed in thinner slices, and the films that play broadly often lack depth.
  • After six weeks in theaters “The Master,” a 70-millimeter character study much praised by critics, has been seen by about 1.9 million viewers. That is significantly smaller than the audience for a single hit episode of a cable show like “Mad Men” or “The Walking Dead.”

  • The weakness in movies has multiple roots. Films, while in theaters, live behind a pay wall; television is free, once the monthly subscription is paid.
  • a collapse in home video revenue, caused partly by piracy, drove film salaries down. Television, meanwhile, raised its pay
  • But the number of films released by specialty divisions of the major studios, which have backed Oscar winners like “Slumdog Millionaire,” from Fox Searchlight, fell to just 37 pictures last year, down 55 percent from 82 in 2002,
  • “So, what does that mean for us as a culture?” Ms. Sylte asked of a vacuum that might occur if the better films went away. The hole, Mr. Gazzale said, to whom the question was relayed, would be a large one. “Movies remind us of our common heartbeat,” he said.

What's the secret to learning a second language? - Salon.com - 0 views

  • “Arabic is a language of memorization,” he said. “You just have to drill the words into your head, which unfortunately takes a lot of time.” He thought, “How can I maximize the number of words I learn in the minimum amount of time?”
  • Siebert started studying the science of memory and second-language acquisition and found two concepts that went hand in hand to make learning easier: selective learning and spaced repetition. With selective learning, you spend more time on the things you don’t know, rather than on the things you already do
  • Siebert designed his software to use spaced repetition. If you get cup right, the program will make the interval between seeing the word cup longer and longer, but it will cycle cup back in just when you’re about to forget it. If you’ve forgotten cup entirely, the cycle starts again. This system moves the words from your brain’s short-term memory into long-term memory and maximizes the number of words you can learn effectively in a period. You don’t have to cram

  • ARABIC IS ONE of the languages the U.S. Department of State dubs “extremely hard.” Chinese, Japanese, and Korean are the others. These languages’ structures are vastly different from that of English, and they are memorization-driven.
  • To help meet its language-learning goals, in 2003 the Department of Defense established the University of Maryland Center for Advanced Study of Language.
  • MICHAEL GEISLER, a vice president at Middlebury College, which runs the foremost language-immersion school in the country, was blunt: “The drill-and-kill approach we used 20 years ago doesn’t work.” He added, “The typical approach that most programs take these days—Rosetta Stone is one example—is scripted dialogue and picture association. You have a picture of the Eiffel Tower, and you have a sentence to go with it. But that’s not going to teach you the language.”
  • According to Geisler, you need four things to learn a language. First, you have to use it. Second, you have to use it for a purpose. Research shows that doing something while learning a language—preparing a cooking demonstration, creating an art project, putting on a play—stimulates an exchange of meaning that goes beyond using the language for the sake of learning it.Third, you have to use the language in context. This is where Geisler says all programs have fallen short.
  • Fourth, you have to use language in interaction with others. In a 2009 study led by Andrew Meltzoff at the University of Washington, researchers found that young children easily learned a second language from live human interaction while playing and reading books. But audio and DVD approaches with the same material, without the live interaction, fostered no learning progress at all. Two people in conversation constantly give each other feedback that can be used to make changes in how they respond.
  • our research shows that the ideal model is a blended one,” one that blends technology and a teacher. “Our latest research shows that with the proper use of technology and cognitive neuroscience, we can make language learning more efficient.” 
  • The school released its first two online programs, for French and Spanish, last year. The new courses use computer avatars for virtual collaboration; rich video of authentic, unscripted conversations with native speakers; and 3-D role-playing games in which students explore life in a city square, acting as servers and taking orders from customers in a café setting. The goal at the end of the day, as Geisler put it, is for you to “actually be able to interact with a native speaker in his own language and have him understand you, understand him, and, critically, negotiate when you don’t understand what he is saying.” 
  • The program includes the usual vocabulary lists and lessons in how to conjugate verbs, but students are also consistently immersed in images, audio, and video of people from different countries speaking with different accents. Access to actual teachers is another critical component.

Write My Essay, Please! - Richard Gunderman - The Atlantic - 1 views

  • Why aren't the students who use these services crafting their own essays to begin with?
  • Here is where the real problem lies. The idea of paying someone else to do your work for you has become increasingly commonplace in our broader culture, even in the realm of writing. It is well known that many actors, athletes, politicians, and businesspeople have contracted with uncredited ghostwriters to produce their memoirs for them. There is no law against it.
  • At the same time, higher education has been transformed into an industry, another sphere of economic activity where goods and services are bought and sold. By this logic, a student who pays a fair market price for it has earned whatever grade it brings. In fact, many institutions of higher education market not the challenges provided by their course of study, but the ease with which busy students can complete it in the midst of other daily responsibilities.

Sleight of the 'Invisible Hand' - NYTimes.com - 1 views

  • The wealthy, says Smith, spend their days establishing an “economy of greatness,” one founded on “luxury and caprice” and fueled by “the gratification of their own vain and insatiable desires.” Any broader benefit that accrues from their striving is not the consequence of foresight or benevolence, but “in spite of their natural selfishness and rapacity.” They don’t do good, they are led to it.
  • Smith described this state of affairs as “the obvious and simple system of natural liberty,” and he knew that it made for the revolutionary implication of his work. It shifted the way we thought about the relationship between government action and economic growth, making less means more the rebuttable presumption of policy proposals.
  • What it did not do, however, was void any proposal outright, much less prove that all government activity was counterproductive. Smith held that the sovereign had a role supporting education, building infrastructure and public institutions, and providing security from foreign and domestic threats — initiatives that should be paid for, in part, by a progressive tax code and duties on luxury goods. He even believed the government had a “duty” to protect citizens from “oppression,” the inevitable tendency of the strong to take advantage of the ignorance and necessity of the weak.

  • In other words, the invisible hand did not solve the problem of politics by making politics altogether unnecessary. “We don’t think government can solve all our problems,” President Obama said in his convention address, “But we don’t think that government is the source of all our problems.” Smith would have appreciated this formulation. For him, whether government should get out of the way in any given matter, economic or otherwise, was a question for considered judgment abetted by scientific inquiry.
  • politics is a practical venture, and Smith distrusted those statesmen who confused their work with an exercise in speculative philosophy. Their proposals should be judged not by the delusive lights of the imagination, but by the metrics of science and experience, what President Obama described in the first presidential debate as “math, common sense and our history.”
