Is street violence an addictive behavior? How does a violence or poverty affect how a child learns, how police deal with crime and how landlords treat tenants? These and other social determinants of health are being studied by Sandra Lane, PhD (at left), a professor of public health at Syracuse University, and Arnett Haygood-El (at right), associate director of the Street Addiction institute Inc. in Syracuse. Health does not exist in a vacuum but as part of a person‘s environment, they explain, and they are seeking solutions to the trauma inflicted by violence and poverty.
