(FORTUNE Magazine) – -- It's new student week at Northwestern University. For the members of the class of 1998 . . . orientation means much more than learning where the library is or how to drop an unwanted course. There's a required session on sexual assault. There's another on alcohol and campus safety. There's one on health that covers subjects from safe sex to wearing a helmet when biking or in-line skating . . . Warning students of potential problems . . . is a good defense in a lawsuit- prone age. Officials are unnerved by cases such as the University of Idaho freshman who this year sued the school for nearly $1 million after he fell out a dormitory window while trying to moon students below. -- From an article in the Chicago Tribune.
