James Hess

Jim Hess is an analyst with the Center for Evidence Based Corrections. He received his Ph.D. from the University of California Irvine School of Social Science in the Program in Social Networks. His dissertation focused on migration, economic development, and globalization, using ethnographic and survey field research in an Orange County immigrant community and across a year’s residence in the Marshall Islands. This project showed the linkage between the dynamics of migration systems and phases in the evolution of globalization, and argued that the sustainability of development projects is a function of regional political economy and international finance, as well as local ecology and institutions. He has also participated in research projects at the Division of Epidemiology, the Center for Public Health and Research, and the UCI Libraries, and has provided consulting on advanced statistical analysis for systematic qualitative data. At the CEBC he is currently focused on recidivism in the parolee population and predictors of the risk of recidivism, with a particular interest in family structures and cohesion, ethnicity, identity, and community/neighborhood effects.
