Sport Is Unrelated To Obesity In Children 594

Posted by kdawson from the who-you-callin-fat dept.
xiox writes "The UK government is planning to stop funding a study to understand obesity in children. The study fits children with accelerometers to measure how much energy each child uses in a day by moving. The results are surprising. Those children who do sports at school do not burn more calories than those who don't. Furthermore there is no correlation between body mass index and the number of calories used! The results are very interesting, suggesting that genetics and diet are the main reasons for childhood obesity, not sport. The UK government is trying to increase the amount of sport in schools."

Natural Language Processing for State Security 132

Roland Piquepaille writes "Obviously, computers can't have an opinion. What computers are very good at, though, is scanning through text to deduct human opinions from factual information. This branch of natural-language processing (NLP) is called 'information extraction' and is used for sorting facts and opinions for Homeland Security. Right now, a consortium of three universities is for the U.S. Department of Homeland Security (DHS) which doesn't have enough in-house expertise in NLP. Read more for additional references and a diagram showing how information extraction is used."

A Fresh Look at Vista's User Account Control 332

Posted by Zonk from the let-me-in dept.
Art Grimm writes to mention a post at Ed Bott's Microsoft Report on ZDNet. There, he talks about Vista's User Account Control, and the issues he sees with the setup as it exists now. From the article: "The UAC prompts I depicted in the first post are those that appear when you install a program, when you run a program that requires access to sensitive locations, or when you configure a Windows setting that affects all users. But as many beta testers have discovered, UAC prompts can also show up when you perform seemingly innocent file operations on drives formatted using NTFS. In this post, I explain why these prompts appear and why some so-called Windows experts miss the obvious reason (and the obvious fix)."
