A significant proportion of university students experience violence, under circumstances that often involve alcohol. A new study has found that drinking at a fraternity, sorority or campus residence increases the likelihood of aggression, and that attending parties can especially increase aggression for women.

The culture of a school can dampen - or exacerbate - the violent or disruptive tendencies of aggressive young teens, new research indicates. A large-scale study from the University of Illinois found that while personal traits and peer interactions have the most direct effect on the aggressive behavior of middle school students, the school environment also influences student aggression.
