NEW BRUNSWICK, N.J. - New Jersey's largest higher education institution is joining a growing number of colleges and universities implementing mobile phone-based warning systems after shootings that left 33 dead at Virginia Tech last week.

Rutgers University said yesterday it would encourage students, faculty and staff on its New Brunswick/Piscataway, Newark and Camden campuses to register their mobile phone numbers with the university so they can receive alert messages during an emergency. The university has created a Web site to record the cell phone numbers, http://alerts.rutgers.edu. "This system is part of our continuing efforts to improve communications at Rutgers and to help keep our community as safe as possible," said Rutgers President Richard L. McCormick.

At Princeton University, the university purchased a mobile phone warning system just days before the Virginia Tech shootings. The new notification system is now in place. - AP
