Broad community initiatives that use local coalitions to reduce alcohol and drug abuse are largely ineffective and may even have a negative effect for some goals, according to a new study of Robert Wood Johnson Foundations Fighting Back campaign.
"Supporting the activities of local coalitions is both intuitively attractive (bringing the community together to address local problems) and politically popular (spreading the money around)," says Denise Hallfors, Ph.D., of the Pacific Institute for Research and Evaluation in Chapel Hill. "What is not clear is whether coalitions actually reduce substance abuse."
The federal government gave nearly half a billion dollars to local anti-drug coalitions in the 1990s and Fighting Back was the RWJFs largest-ever demonstration program.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
