Brown and Duke universities — two of the nation’s elite schools — are cracking down on illegal behavior at parties this semester, with each college sanctioning fraternities in the past week as part of an effort to curb excessive drinking and address sexual assault. Brown University, in Providence, R.I., sanctioned two fraternities and banned registered events with alcohol in on-campus residences such as Greek system houses, while Duke University has suspended its Alpha Delta Phi fraternity chapter amid allegations of sexual assault in the fraternity’s off-campus house.
