For example, a classroom teacher might drill students repeatedly on the same multiplication problem, with very little delay between the first and second presentations of the problem, ensuring that the student gets the answer correct each time. The idea embedded in this approach is that if students make errors, they will learn the errors and be prevented (or slowed) in learning the correct information. But research by Nate Kornell, Matthew Hays and Robert Bjork at U.C.L.A. that recently appeared in the Journal of Experimental Psychology: Learning, Memory and Cognition reveals that this worry is misplaced. People remember things better, longer, if they are given very challenging tests on the material, tests at which they are bound to fail. This work has implications beyond the classroom.

Mental State Called Flow A number of sources, most recently ProgrammingOutsideTheCube and the RingerTape page, say that many folk find it takes time to get into a state where work flows. Do you plan to get into flow, does it come upon you more as a kind of inspiration, or is it not necessary for you? Do you use tactics to improve your team's ability to flow? Which particular events disrupt flow the most, and how do you solve them? Interesting but difficult to summarize: The mental state that psychologists call "flow", and its impact on your project, are well described in chapter 10 ("brain time versus body time") of PeopleWare. About 20-30 minutes of Zen meditation once or twice per day should be a great help. I find problems draw me into them. Flow to me is evidenced in looking up ten minutes later to find that hours have elapsed. MicroSoft has a tack on this sort of thing. I use to get into flow around 9pm, but nowadays I just get sleepy... Try juggling.

Inside the Data Mine On April 20, 2007, former Qwest telecommunications CEO Joseph Nacchio was found guilty on 19 of 42 counts of insider trading. “For anyone who has ever made a call in Qwest territory, the term ‘convicted felon Joe Nacchio’ has a nice ring to it,” U.S. prosecutor Troy Eid told the press. The mood was fairly universal. One securities lawyer pitched in: “The government has another notch in their belt. They’ve had a tremendous winning streak in these corporate crime cases.” But it would have been more accurate to qualify the statement by saying that the government has had a tremendous winning streak in the corporate crime cases it chooses to pursue. In the wake of the Enron scandal, Nacchio’s verdict could be seen as the continuing triumph of an efficient and unbiased judicial system—one working to protect the people’s interests against unbridled business tycoons.

EU proposes greater data sharing between police forces High performance access to file storage The German Presidency of the European Union wants police forces across Europe to be able to share data more freely and wants a single body to be in charge of overseeing the process. The changes are contained in a framework decision proposed by the Presidency to the European Commission designed to outline the protections citizens can expect when their personal data is handled by police and judicial authorities. The suggested framework decision proposes greater police cooperation on data sharing and the legalisation of more sharing of information on individuals between national forces and between those forces and Europol. The proposal suggests allowing personal data gathered in one state and shared with another to be transferable to a third EU Member State, or even outside of the EU. The proposal does not extend to national security matters which have always been seen as the prerogative of member states. Copyright © 2007, OUT-LAW.com
