Study Says World's Stocks Controlled by Select Few | Research - ISNS
"A pair of physicists at the Swiss Federal Institute of Technology in Zurich did a physics-based analysis of the world economy as it looked in early 2007. Stefano Battiston and James Glattfelder extracted the information from the tangled yarn that links 24,877 stocks and 106,141 shareholding entities in 48 countries, revealing what they called the "backbone" of each country's financial market. These backbones represented the owners of 80 percent of a country's market capital, yet consisted of remarkably few shareholders. [..] The results will be published in an upcoming issue of the journal Physical Review E."

Twitter Study Reveals Interesting Results About Usage | Pear Analytics
"So we took 2,000 tweets from the public timeline (in English and in the US) over a 2-week period from 11:00a to 5:00p (CST) and captured tweets in half-hour increments. Then we categorized them into 6 buckets: News, Spam, Self-Promotion, Pointless Babble, Conversational and Pass-Along Value. The results were interesting. As you may have guessed, Pointless Babble won with 40.55% of the total tweets captured; however, Conversational was a very close second at 37.55%, and Pass-Along Value was third (albeit a distant third) at 8.7% of the tweets captured."

Bokode - Camera Culture Group, MIT Media Lab
"Current optical tags, such as barcodes, must be read within a short range and the codes occupy valuable physical space on products. We present a new low-cost optical design so that the tags can be shrunk to 3mm visible diameter, and unmodified ordinary cameras several meters away can be set up to decode the identity plus the relative distance and angle. The design exploits the bokeh effect of ordinary cameras lenses, which maps rays exiting from an out of focus scene point into a disk like blur on the camera sensor. This bokeh-code or Bokode is a barcode design with a simple lenslet over the pattern. We show that an off-the-shelf camera can capture Bokode features of 2.5 microns from a distance of over 4 meters."

The Effect of Country Music on Suicide
"Country music is hypothesized to nurture a suicidal mood through its concerns with
problems common in the suicidal population, such as marital discord, alcohol abuse, and
alienation from work. The results of a multiple regression analysis of 49 metropolitan
areas show that the greater the airtime devoted to country music, the greater the white
suicide rate. The effect is independent of divorce, southernness, poverty, and gun
availability. The existence of a country music subculture is thought to reinforce the link
between country music and suicide."

Napping: the expert's guide | Life and style | The Guardian
A nap of 60 minutes improves alertness for up to 10 hours. Research on pilots shows that a 26-minute "Nasa" nap in flight (while the plane is manned by a copilot) enhanced performance by 34% and overall alertness by 54%. One Harvard study published last year showed that a 45-minute nap improves learning and memory. Napping reduces stress and lowers the risk of heart attack and stroke, diabetes, and excessive weight gain.

Feeling ill? It could be the planets, says govt study- Hindustan Times
The five-year study, nearing completion, is being conducted by the Delhi-based Lal Bahadur Shastri Rashtriya Sanskrit Vidyapeetha’s department of medical astrology. The department has been recording the birth details of patients and their medical history from Delhi hospitals, and has a databank of over 1,000 horoscopes. In nearly 75 per cent cases, a strong co-relation is found between the prediction of occurrence of a disease at a specific time and its occurrence,” Dr Prem Kumar Sharma, head of the medical astrology department, told HT.

poslovni.hr - Vukmir: Stopa piratstva niža za 10% otvara tisuću radnih mjesta
Tako bi, prema IDC Studiji o gospodarskim učincima softverskog piratstva, smanjenjem stope softverskog piratstva za samo 10% Hrvatska do 2009. otvorila više od tisuću novih radnih mjesta u IT sektoru, te bi se nacionalnom gospodarstvu donijelo dodatnih 247 milijuna američkih dolara. Osim toga, prihodi nacionalne industrije povećali bi se za više od 150 milijuna američkih dolara, te bi se ostvarilo dodatnih 63 milijuna USD poreznih prihoda. Općenito, utjecaj intelektualnog vlasništva na gospodarstvo iznimno je velik, što potvrđuje Studija o ekonomskom doprinosu djelatnosti temeljenih na autorskom pravu u gospodarstvu Hrvatske koju je lani objavio Državni zavod za intelektualno vlasništvo, a iz koje je vidljivo da industrije koje svoje poslovanje temelje na autorskim pravima ostvaruju veći prihod u iznosu od 4,42% BDP-a od svih hotela i restorana koji ostvaruju 3,61 posto BDP-a.

Study of Bush's psyche touches a nerve | World news | The Guardian
A study funded by the US government has concluded that conservatism can be explained psychologically as a set of neuroses rooted in "fear and aggression, dogmatism and the intolerance of ambiguity". As if that was not enough to get Republican blood boiling, the report's four authors linked Hitler, Mussolini, Ronald Reagan and the rightwing talkshow host, Rush Limbaugh, arguing they all suffered from the same affliction. All of them "preached a return to an idealised past and condoned inequality". Republicans are demanding to know why the psychologists behind the report, Political Conservatism as Motivated Social Cognition, received $1.2m in public funds for their research from the National Science Foundation and the National Institutes of Health.
The authors also peer into the psyche of President George Bush, who turns out to be a textbook case. The telltale signs are his preference for moral certainty and frequently expressed dislike of nuance.
"This intolerance of ambiguity can lead people to cling to the familiar, to arrive at premature conclusions, and to impose simplistic cliches and stereotypes," the authors argue in the Psychological Bulletin.

My eBay Job | Print Article | Newsweek.com
it concluded that "approximately 1.3 million sellers around the world use eBay as their primary or secondary source of income," with an estimated 630,239 in the United States. Take careful note of the phrasing, however: primary or secondary. That could mean 50,000 use eBay as a primary source and 1.25 million as a secondary source. Or it could mean the split is closer to 650,000-650,000.

Our Own Worst Critic | Print Article | Newsweek.com
We are all called upon everyday to read others, to interpret how we look in their eyes. Whether in a job interview, a musical audition or a first date, it's basic human nature to calculate how we're doing as performers in life. But we so often get it wrong, believing we did far better or far worse than we did in fact. Why are we so poor at intuiting what others think of us?

The Popularity Gap | Print Article | Newsweek.com
Figuring out whether you'll end up being a cool prom king or queen bee--or the kid who eats alone in the cafeteria--is an integral part of becoming a teenager.
Turns out, it doesn't necessarily matter. Whether or not your high class voted you "most popular," teenagers who perceive themselves as well liked are just as socially successful over time as the kids who actually are part of the in-crowd, according to a new study in the May-June issue of Child Development. In fact, the overlap between the kids who believe they're popular and those who are deemed popular by their peers is pretty small. "Certainly there's a subset that feels good about themselves and is also popular, but that isn't the majority," says Kathleen Boykin McElhaney, a research associate in psychology at University of Virginia who conducted the study. Her findings add to a growing body of research suggesting that our perception of how we fit into the social world is just as important--if not more important--than our real-life position in the social world.

Study revives Olympic prospects for amputee sprinter
Specifically, the scientists concluded that:
* Pistorius’ ability to maintain speed over the course of longer sprints--his speed-duration relationship--is essentially identical to that of able-bodied runners, indicating that he fatigues in the same manner as able-bodied sprinters.
* Pistorius’ rates of metabolic energy expenditure do not differ from elite non-amputee runners. In particular, he has nearly the same running economy, or rate of oxygen consumption at submaximal speeds, and a similar maximal rate of oxygen consumption as elite non-amputee runners.
"Based on the data collected at Rice, the blades do not confer an enhanced ability to hold speed over a 400m race," Weyand said. "Nor does our research support the IAAF's claims of how the blades provide some sort of mechanical advantage for sprinting."
“The study commissioned by the IAAF claimed that Pistorius has a 25 percent energetic advantage at 400m race speeds. That claim is specious because anaerobic energy supply cannot be quantified,” Kram said.
In summary, the team of experts unanimously concluded that the IAAF allegations were not scientifically valid.

Weight discrimination "occurs in employment settings and daily interpersonal relationships virtually as often as race discrimination, and in some cases even more frequently than age or gender discrimination," the researchers report in the current issue of the International Journal of Obesity.
Why Apple fans hate tech reporters - Machinist - Salon.com
-
But there is no bigger tribe, and none more zealous, than fans of Apple, who are infamous for their sensitivity to slams, real or imagined, against the beloved company. "It's funny -- even if I write a generally positive piece about Apple, I still get more complaints from Apple partisans" than from opponents, Mossberg says. He has even coined a term for the effect. "I call it the Doctrine of Insufficient Adulation."
Music special: Five great auditory illusions - being-human - 20 February 2008 - New Scientist
-
Here we have compiled five of the most striking auditory illusions discovered so far.
We had a big pool to choose from, from the mysterious quintina (fifth voice) heard in some types of throat-singing, to the saxophone solo that isn't on Lady Madonna (it's actually the Beatles singing into their cupped hands) and the soaring guitar sound of Pink Floyd's Dave Gilmour. Listen to our top 5 below, and read our explanations of the effects involved.
