If you would like to read more about school related violence and the differences in girl and boy motivations for anger etc. take a look at my article (with Sandra Thomas) here entitled "School Connectedness, Anger Behaviors, and Relationships of Violent and Nonviolent American Youth" or if you want a good book on the topic, try Odd Girl Out: The Hidden Culture of Aggression in Girls.
