The 2009 Lipsitt-Duchin Lectures in Child and Youth Behavior and Development, entitled, “Prevention Youth Violence New Strategies for Policy, Practice and Research,” will feature a panel of nationally recognized experts, including pioneers working directly with street gangs, who will discuss the origins and consequences of criminal behavior, including violence. They will address the harm that youthful delinquency can do to the public as well as the youth themselves, and will present evidence-based interventions known to help make children, youth and their communities safer. This event begins at 3:30 p.m. in MacMillan Hall, Starr Auditorium.
