[简答题]As they do every week, the 90 members of the Sigma Phi Epsilon fraternity at Oregon State University file into their dining hall for a very different kind of frat party. The rows of scrubbed and pressed young men sit down to eat under the watchful eye of the brother who is acting as manners chair. No swearing is permitted. Napkins on laps are required. Small bites are urged instead of gulps. Scofflaws must do penalty push-ups or pay a fine into the piggy bank in the middle of each table.

As colleges continue to crack down on binge drinking, hazing and general hooliganism, some fraternities are redefining the Greek experience in order to save it.
Oregon State’s is among the 256 SigEP chapters nationwide that have adopted the Balanced Man Program, an intensive four-year fraternity experience created 13 years ago
