Software Used To Predict Who Might Kill. eldavojohn writes "Richard Berk, a University of Pennsylvania criminologist, has worked with authorities to develop a software tool that predicts who will commit homicide. I could not find any papers published on this topic by Berk, nor any site stating what specific Bayesian / decision tree algorithm / neural net is being implemented." From the article: "The tool works by plugging 30 to 40 variables into a computerized checklist, which in turn produces a score associated with future lethality. 'You can imagine the indicators that might incline someone toward violence: youth; having committed a serious crime at an early age; being a man rather than a woman, and so on. Each, by itself, probably isn't going to make a person pull the trigger. But put them all together and you've got a perfect storm of forces for violence,' Berk said. Asked which, if any, indicators stood out as reliable predicators of homicide, Berk pointed to one in particular: youthful exposure to violence." The software is to enter clinical trials next spring in the Philadelphia probation department. Its intent is to serve as a kind of triage: to let probation caseworkers concentrate most of their effort on the former offenders most likely to be most dangerous [Slashdot] 5:43:39 PM      Google It!.

OpenDocument Now Published ISO Standard. bobibobi writes "After months of revisions, OpenDocument receives status of a full published standard. The various stages of a standard's "stage code are also online." The OpenDocument standard has been developed by a variety of organizations and is publicly accessible. This means it can be implemented into any system, be it free software/open source or a closed proprietary product, without royalties.[Slashdot] 5:40:50 PM      Google It!.

Taxing Virtual Gaming Assets. rijit writes "It appears very likely that taxation of online games assets is inevitable. Quote: 'That's because game publishers may well in the not too distant future have to send the forms [~] which individuals receive when earning nonemployee income from companies or institutions [~] to virtual world players engaging in transactions for valuable items like Ultima Online castles, EverQuest weapons or Second Life currency, even when those players don't convert the assets into cash.'

Hunting the elusive search strategy. Last night an old friend who runs a small software company confessed a secret. When he and his staff answer technical questions for clients, they are often "only" searching Google. At one point, he even asked a client: "Do you really want us to search Google for you at $100/hour?" Yes, in fact they did. My friend thought that was crazy. I suggested that it's not as crazy as it sounds. Effective search depends on reservoirs of tacit knowledge and unconscious skill. Some people possess much deeper reservoirs, and/or can tap into them more effectively, than others. That makes them valuable. ... [Jon's Radio] 5:27:47 PM      Google It!.

Detecting Tailgaters With Lasers. stoolpigeon writes "Police in Arizona are using laser range finders to detect and ticket tailgaters. An officer can now measure not only the speed of passing vehicles but also how close they are to one another. The detectors described in the article are built by Laser Technology Inc., a company that provides lasers for traffic control, engineering, and even tactical/military solutions. The article mentions how tailgating is connected to many accidents and incidents of road rage."[Slashdot] 5:24:41 PM      Google It!.

Novell "Forking" OpenOffice.org. l2718 writes to mention that In the wake of their recent deal with Microsoft, Novell has announced a new version of OpenOffice.org which will support Microsoft's planned Office formal, Open XML. From the article: "The translators will be made available as plug-ins to Novell's OpenOffice.org product. Novell will release the code to integrate the Open XML format into its product as open source and submit it for inclusion in the OpenOffice.org project. As a result, end users will be able to more easily share files between Microsoft Office and OpenOffice.org, as documents will better maintain consistent formats, formulas and style templates across the two office productivity suites."

Microsoft's Lobbying In Massachusetts. Andy Updegrove writes "Carol Sliwa at ComputerWorld has posted two excellent stories just now on ODF in Massachusetts, based on over 300 emails secured under the Massachusetts Public Records Law (the local analogue of the Federal Freedom of Information Act). The longer and more intriguing article focuses on Microsoft's lobbying efforts in Massachusetts, and confirms, as I reported last week, that Microsoft lobbyist Brian Burke was spearheading an effort to bring pressure on the state's Information Technology Division (ITD) by promoting an amendment that would have taken away much of the ITD's power to make technology policy. The article goes on to describe the back-channel negotiations between State CIO Louis Gutierrez and Microsoft's Alan Yates, and the way that Microsoft played the lobbying card throughout those discussions in an effort to protect its wildly profitable Office software franchise against potential erosion by competing products that support ODF." Andy has a blog entry on the lobbying effort. [Slashdot] 3:08:42 PM      Google It!.

Computer Simulation of Cancer Growth. Roland Piquepaille writes "For a long time now, researchers and scientists have used computer simulations in the physical sciences: physics, chemistry, and engineering. But what about biology? An international team of U.S. and Scottish mathematicians and biologists has built a math model to predict tumor behavior. The researchers say their approach is similar to the one used by weather forecasters. So far, this approach is entirely theoretical. But the scientists see their effort as the beginning of a new era in cancer research — 'a sea change in how biology is being done,' as the lead researcher described it. Read more for additional references and illustrations about this use of computer simulation to predict a cancer evolution." [Slashdot] 3:05:39 PM      Google It!.
