“I find that companies tend to disclose favorable news just before CEOs leave for vacation and then hold over subsequent news announcements until they return to headquarters.  During periods when CEOs are away from the office, stock prices behave quietly with sharply lower volatility than usual.  Volatility increases immediately when CEOs return to work.”

#essayIs Facebook making us lonely?

“If you use Facebook to communicate..—by using the “like” button, commenting on friends’ posts, and so on—it can increase your social capital.  Personalized messages, or what Burke calls “composed communication,” are more satisfying than “one-click communication”—the lazy click of a like. “People who received composed communication became less lonely, while people who received one-click communication experienced no change in loneliness,” “

#1Read_this_Week – Feltron Report 2010/11

“Philip K. Dick claimed that “a person’s authentic nature is a series of shifting, variegated planes that establish themselves as he relates to different people; it is created by and appears within the framework of his interpersonal relationships.”

The Feltron 2010/2011 Biennial Report explores this notion by overlapping facets of Nicholas’ behavior to visualize how his personality varies based on location and company.”

#big_data – Data Mining You

“He wrote a piece for Wired magazine on a super-secret, $2 billion, one-million-square-foot data center the NSA is building in Bluffdale, Utah.  Focused on data mining and code-breaking and five times the size of the U.S. Capitol, it is expected to house information beyond compare, “including the complete contents of private emails, cell phone calls, and Google searches, as well as all sorts of personal data trails — parking receipts, travel itineraries, bookstore purchases, and other digital ‘pocket litter.’”

 

#Data_Science – How to use ‘I.Q. math’ to solve more murders (or, Chess, Intelligence and Winning Arguments)

“It is also known that the mean IQs of murderers and policemen are 87 and 102, respectively. So successfully solving murders is a puzzle then the “a” coefficient is 0.041, and each IQ point difference is worth 7.2 ELO points. A 3 fold advantage could be had with a 28 point gap between cops and killers. In other words some 31% of outstanding murders could be solved if the USA selected its policemen to have an average IQ of 125 i.e. to be as smart as an average lawyer.

#essayShort note on time scales and ensuing discussion

“So when someone says that Solid State Disks are awesome, it’s because they’re able to turn that slow, unpredictable old sailing ship into a streamlined steam-powered vessel. A good SSD can often make the voyage in less than a week, sometimes in little more than a day. It can also make many thousands more quests for information per year.”
