Article: Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager's intended major, one located near a large city, and a campus where their daughter would be safe. "The safety issue is a big one," says Joe Mahoney, who quickly discovered he wasn't alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer -----"That's not a problem here,"-----Mahoney began to feel uneasy. "No crime whatever?" comments Mahoney today. "I just don't _ it." Nor should he: in 1999 the U.S. Department of education had reports of nearly 400,000 serious crimes on or around our campuses. "Parents need to understand that times have changed since they went to college," says David Nichols, author ofCreating a Safe Campus. "Campus crime mirrors the rest of the nation." But getting accurate information isn't easy. Colleges must report crime statistics by law, but some hold back for fear of bad publicity , leaving the honest ones looking dangerous. "The truth may not always be serious," warns S. Daniel Carter of Security on Campus, Inc., the nation's leading campus safety watchdog group. To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.

Article: It is reasonable to say that every teenager can be affected by peer pressure at some point. Every day, in any high school, peer pressure has a major influence over the behavior of teenagers. It can be as subtle as being persuaded to be late for class or as extreme as a dangerous drug. Whether subtle or extreme, peer pressure can have damaging, sometimes life changing, and even serious results. "Teens don't often consider the long-term results that some behavior can cause," said Terri Price, a researcher. "Peer pressure can be very difficult to handle for many teens because of their fears of not fitting in". Peer pressure has always been part of teen life, but teens experience _ differently than their former generations did in the past. Sources of peer pressure have increased because of the Internet and other electronic communications. Recognizing peer pressure can be as simple as noticing that you have been asked to do something that you are not comfortable with. "Listen to your instinct , which is a sign for whether something is right or wrong. If it feels wrong, then most likely it is. "says Price. Teens are in a time of life when they are still discovering who they are. Many teens are influenced by peer pressure because of their insecurities . This can make them helpless especially when their self-control is weak or they lack healthy support, causing them to take risky behavior or turn to unhealthy support. Dealing with peer pressure is a topic of concern for teens. People can say, "Just say no," but the truth is that the statement is easier said than done.
