The Visiting Fellowship program allows practitioners and researchers to pursue special areas of study for 6 to 18 months at NIJ. They also have the opportunity to interact with NIJ staff and with national leaders in criminal justice. Among the projects described are a law professor's study of jail masters, a sociology professor's indepth research on privately operated prisons, and a California local official's report on new methods for constructing prisons and jails. Other areas being explored by Fellows include victim decisionmaking, ways to prevent crime in urban ghettos, and legal issues involved in prosecuting and investigating child sexual abuse cases. One Fellow is preparing a manual for practitioners on drug testing of offenders and helping set up the Drug Use Forecasting System. The paper also highlights distinguished alumni of the program and provides information on the application process. Photographs.
