Increasing Retention Without Increasing Study Time
ABSTRACT Because people forget much of what they learn, students could benefit from learning strategies that yield long-lasting knowledge. Yet surprisingly little is known about how long-term retention is most efficiently achieved. Here we examine how retention is affected by two variables: the ...

Computers determine when to stop searches at sea
Researchers are developing a new computer model to predict how long someone will survive when lost at sea, which will in turn determine when a search and rescue operation may be stopped. The Search and Rescue Survival Model is being developed by the University of Portsmouth’s Sports Science and ...

'Six Degrees of Kevin Bacon' game provides clue to efficiency of complex networks
The underlying success of this phenomenon called the "small-world paradigm," discovered in the 1960s by sociologist Stanley Milgram, recently provided a source of inspiration for researchers studying the Internet as a global complex network. The result, a study by Mari? Bogu?, Dmitri Krioukov, ...

It just goes to show what studies done with sufficient hard data can "discover". So, what shall one now make ... -

Study finds many motorists don't see need to heed speed limits [high DUH factor warning]
Comment added by JDP on 11/07/2008Ever notice what happens on crowded highways when speed enforcement is merely visible, but even more so when that involves traffic stops? MORE ACCIDENTS (from "rubber-necking" slow downs)! Hence, police in many major cities specifically AVOID busy highways during high traffic times - ... -

An Intuitive Explanation of Bayesian Reasoning
Comment added by Jairo Chapela-Martínez on 10/28/2008I think an Information Theory approach can be useful here in order to understand and quantify evidence and credibility. It's all about computing the mutual information between priors and tests' results.
