Excel Error Contributes To Problems With Austerity Study

quarterbuck writes “Many politicians, especially in Europe, have used the idea that economic growth is impeded by debt levels above 90% of GDP to justify austerity measures. The academic justification came from a paper and a book by Kenneth Rogoff and Carmen Reinhart. Now researchers at U Mass at Amherst have refuted the study — they find that not only was the data tainted by bad statistics, it also had an Excel error . Apparently when averaging a few GDP numbers in an excel sheet, they did not drag down the cell ranges down properly, excluding Belgium. The supporting website for the book ‘This time it is different’ has lots of financial information if a reader might want to replicate some of the results.” The Excel error is making the rounds as the cause of the problems with the study, but it’s actually a minor component. The study also ignores some post-WWII data for countries that had a high debt load and high growth, and there’s some fishy weighting going on: “The U.K. has 19 years (1946-1964) above 90 percent debt-to-GDP with an average 2.4 percent growth rate. New Zealand has one year in their sample above 90 percent debt-to-GDP with a growth rate of -7.6. These two numbers, 2.4 and -7.6 percent, are given equal weight in the final calculation, as they average the countries equally. Even though there are 19 times as many data points for the U.K.”

Study Shows Censorship On Sina Weibo Is A ‘Sophisticated’ And Very Speedy Operation
Posted by Gsurface
on March 27, 2013
No comments
Known as the Twitter of China, Sina Weibo is also infamous in the West for the number of high profile users who have had tweets censored, including Kai-fu Lee. The former head of Google China, who was once booted off Sina and Tencent Weibo for three days, recently made a graph of how often his microblogging posts have been censored. Computer scientists Jed Crandall and Dan Wallach conducted a study on how quickly censorship on Sina Weibo can work, with findings reported by the BBC and originally published on arXiv.org. The two researchers, who believe their study is the first “real-time analysis of Weibo posts,” say they “found a landscape in which a post could be deleted as quickly as five minutes after being put online and where the censors appear not to work a regular day, but seem to take a break when China’s all-important 19:00 news comes on.” Censors work rapidly: most deletions happened within the first hour after a post had been made, with about five percent of deletions happening within the first eight minutes, and 30 percent in the first half hour. Nearly 90 percent were made within the first 24 hours. Crandall and Wallach spent 30 days tracking posts by 3,500 users on Sina Weibo. During that time, they write, 300 of the accounts, or 12 percent of the total, were deleted. Accounts that got censored the most often also had posts censored the most quickly, showing that they might be the target of more scrutiny. Though they could not estimate the exact number of people dedicated to deleting posts on Sina Weibo, the two computer scientists said that Sina Weibo would need to employ at least 4,000 censors every day if none of the process was automated. Crandall and Wallach called censorship a “sophisticated operation,” with “relatively sophisticated programmers who build their censorship tooling.” Automated systems appear to include keyword alerts for sensitive topics, as well as monitors for certain users who write frequently about sensitive issues. Launched in 2010, Sina Weibo has 300 million users, with about 100 million messages sent daily.

Scientists Study Getting an Unwanted Tune Out of Your Head

on March 26, 2013

Hugh Pickens writes writes “Richard Gray reports that scientists have found a way to help anyone plagued by those annoying tunes that lodge themselves inside our heads and repeat on an endless loop — when snippets of a catchy song inexplicably play like a broken record in your brain. The solution can be to solve some tricky anagrams to force the intrusive music out of your working memory allowing the music to be replaced with other more amenable thoughts. ‘The key is to find something that will give the right level of challenge,’ says Dr Ira Hyman, a music psychologist at Western Washington University who conducted the research. ‘If you are cognitively engaged, it limits the ability of intrusive songs to enter your head.’ Hyman says that the problem, called involuntary memory retrieval, is that something we can do automatically like driving or walking means you are not using all of your cognitive resource, so there is plenty of space left for that internal jukebox to start playing. Dr Vicky Williamson, a music psychologist at Goldsmiths, University of London, says that the most likely songs to get stuck are those that are easy to hum along to or sing and found that that Lady Gaga was the most common artist to get stuck in people’s heads, with four of her catchy pop songs being the most likely to become earworms – Alejandro, Bad Romance, Just Dance and Paparazzi. Other surveys have reported Abba songs such as Waterloo, Changes by David Bowie or the Beatles’ Hey Jude.”

UC Davis Study Concludes H-1B Workers Neither Best Nor Brightest

CowboyRobot writes “American companies are demanding more H-1B visas to ensure access to the best and brightest workforce, and outside the U.S. are similar claims of an IT worker shortage. Last month, European Commission VP Neelie Kroes bemoaned the growing digital skills gap that threatens European competitiveness. But a new study finds that imported IT talent is often less talented than U.S. workers. Critics of the H-1B program see it as a way for companies to keep IT wages low, to discriminate against experienced U.S. workers, and to avoid labor law obligations. In his examination of the presumed correlation between talent and salary, researcher Norman Matloff observes that Microsoft has been exaggerating how much it pays foreign workers. Citing past claims by the company that it pays foreign workers ‘$ 100,000 a year to start,’ Matloff says the data shows that only 18% of workers with software engineering titles sponsored for green cards by Microsoft between 2006 and 2011 had salaries at or above $ 100,000.”

NASA launches Landsat 8 satellite to better study the skies above, water below

NASA’s Landsat program recently turned the big four-oh, and what better way to deal with the mid-life crisis by getting a new satellite as a present? Accordingly, the space agency has just launched Landsat 8 into orbit to give its Earth Science program a new injection of youth. The new vehicle improves the accuracy of existing light and thermal sensors while widening the scope to better reflect modern climate studies — number 8 now tracks aerosols in the atmosphere, high cirrus clouds and the telltale signs of water quality and consumption levels. We won’t get the first USGS-derived results from the new satellite until after a 100-day shakedown period, but we’re sure the deeper understanding of our planet will help the Landsat program forget all about those first few gray hairs.

Us humans are surprisingly familiar with Mars’ surface, yet we haven’t studied its higher altitudes — an odd discrepancy when the sky plays as much of a role as the soil in determining the planet’s climate. We’ll get a better balance in our research now that NASA and Lockheed Martin have finished constructing the Mars Atmosphere and Volatile Evolution probe, or MAVEN. The robot craft will learn how quickly the Martian atmosphere is escaping into space and give us a better idea of how the planet’s arid landscape came to be. Lockheed Martin still needs to conduct space simulation tests and ship MAVEN to the Kennedy Space Center, but the ship should launch in November and deliver results roughly a year later; that’s a quick turnaround for a probe that could answer riddles spanning millions of years.

The conclusion: cyber security (by Microsoft’s definition: low rates of malware infection) correlated positively with many characteristics of wealthy nations – high Gross Income Per Capita, higher broadband penetration and investment in R&D and high rates of literacy. It correlated negatively with characteristics common in poorer nations – like demographic instability, political instability and lower levels of education.’”

Stanford seizes 1 million processing cores to study supersonic noise

In short order, the Sequoia supercomputer and its 1.57 million processing cores will transition to a life of top-secret analysis at the National Nuclear Security Administration, but until that day comes, researchers are currently working to ensure its seamless operation. Most recently, a team from Stanford took the helm of Sequoia to run computational fluid dynamics simulations — a process that requires a finely tuned balance of computation, memory and communication components — in order to better understand engine noise from supersonic jets. As an encouraging sign, the team was able to successfully push the CFD simulation beyond 1 million cores, which is a first of its kind and bodes very well for the scalability of the system. This and other tests are currently being performed on Sequoia as part of its “shakeout” period, which allows its caretakers to better understand the capabilities of the IBM BlueGene/Q computer. Should all go well, Sequoia is scheduled to begin a life of government work in March. In the meantime, you’ll find a couple views of the setup after the break.

Pew Study Suggests Libraries (And Print) Still Have A Future In An E-Book World

Pew found that in the past 12 months, 53 percent of Americans who are 16 or older visited a library or bookmobile, 25 percent visited a library website, and 13 percent visited a library website using a smartphone or tablet. Of those “recent library users,” 26 percent said their usage has gone up in the past five years — the most commonly given reasons were the enjoyment of taking children and grandchildren, the need to do research and use reference materials, and plain old borrowing books more. Meanwhile, 22 percent said their usage had gone down, and the biggest reason by far was the Internet.

The committee’s executive director, Paul Teller, sent a memo today disavowing the earlier pro-copyright reform brief. From the memo: ‘Yesterday you received a Policy Brief or [sic] copyright law that was published without adequate review within the RSC and failed to meet that standard. Copyright reform would have far-reaching impacts, so it is incredibly important that it be approached with all facts and viewpoints in hand.’ People who live in districts such as Ohio’s 4th would do well to send letters of support to those who crafted the original brief. I cannot imagine party leadership will be happy with so radical a suggestion as granting copyright protection for the limited times needed to promote the progress of science and useful arts.”
