How can anyone juggle so many complicated decisions? Do those seeking office have a unique approach to decision making? Studies have suggested that power changes not only a person's responsibilities, but also the way they think. Now, a new study in the December issue of Psychological Science, a journal of the Association for Psychological Science, indicates that having power may lead people to automatically think in a way that makes complex decision-making easier. http://phys.org/news148067935.html Medicine & Health Tue, 09 Dec 2008 17:58:55 EST news148067935 A technology that is adapted to the special conditions for wave energy places the wave energy technology from Uppsala on the absolute cutting edge in the world.
