...follow when looking for a face, or by showing it a sample set of hundreds, if not thousands, of images and letting it figure out what the ones with faces have in common. In this way, a computer can create its own list of rules, and then programmers will tweak them. You might think the more images - and the more diverse the images - that a computer is fed, the better the system will get, but sometimes the opposite is true. The images can begin to generate rules that contradict each other. "If you have a set of 95 images...

Helping the less fortunate in this context becomes a form of civil and corporate disobedience, and Dodson, a professor of sociology at Boston College, isn't lacking in examples. There's the supervisors who tweak time cards so that employees can take care of their kids, the school nurse who keeps cots in her office so that students in difficult family situations can catch a few hours' sleep, and the doctor who flouts insurance regulations in order to prescribe medicine for an entire household...

Because of this, both Levey and Grimes say the more effective approach to the issue may be educating listeners about the problems that can arise. As president of the American Academy of Audiology, Grimes helped start an initiative called Turn It to the Left, which was aimed at informing people about the dangers of prolonged exposures to loud noise. And Levey says that during her study, talking to people about the risks...
