We build a simple model to capture the major virtues and drawbacks of making public officials accountable (i.e., subjecting them to reelection): On the one hand, accountablity allows the public to screen and discipline their officials; on the other, it may induce those officials to pander to public opinion and put too little weight on minority welfare. We study when decision-making powers shoul...

The ability to judge another individual's romantic interest level-both toward oneself and toward others-is an adaptively important skill when choosing a suitable mate to pursue. We tested this ability using videos of individuals on speed dates as stimuli. Male and female observers were equally good at predicting interest levels, but they were more accurate when predicting male interest: Predict...

In this issue of Circulation: Cardiovascular Interventions, Kang et al1 compare intravascular ultrasound (IVUS) parameters against a gold standard of fractional flow reserve (FFR) for evaluating intermediate stenoses. Their work adds another piece of evidence to a debate whose outcome is fundamentally changing interventional cardiology. As encapsulated by the title of the “FFR versus Angiograph...

Self-management, self-connection and selfconfiguration capabilities are emerging as important requirements for a generation of large-scale, highly dynamic, distributed applications. We propose a new solution to manage the connection of the components in a distributed application automatically. Each component in the distributed application is equipped with an autonomous connection unit (ACU). Th...
