at Iowa State University. She joined the Iowa State faculty and was named director of the Center in 1994. Her research interests include international and domestic development, community, and the sociology of science and technology, particularly as related to agriculture and participatory change. Her current research includes work on the generation of social capital in community development, community, sustainable agriculture and natural resource management, with particular attention to how class, gender, and ethnicity influence and are affected by technology and policy. Many of her articles have been widely used by nonprofit organizations that work with farmer groups, particularly in sustainable agriculture, to build stronger communities and a stronger economic base. She has held several academic positions and has also been a program officer for the Ford Foundation. In addition to her responsibilities at the Center, she works on international development issues with the World Bank and the U.S. Agency for International Development. Dr. Flora received a BA from the University of California, Berkeley, and an MS and PhD from Cornell University, which recognized her with an Outstanding Alumni Award in 1994.

James C. Hanson is an extension economist at the University of Maryland, College Park. His research interests include sustainable agriculture, cropping systems, organic agriculture, agricultural extension systems, environmental policy, and farm management. He received his PhD in agriculture and resource economics from the University of Maryland, an MS in plant breeding and genetics from the University of Minnesota, and a BS in agronomy from the University of Maryland.

Douglas Jackson-Smith is an associate professor of sociology at Utah State University. Dr. Jackson-Smith joined the faculty at Utah State University in the summer of 2001, where he currently serves as the director of graduate studies in the Sociology Program. His principal teaching and research interests include the sociology of agriculture, natural resources, and the environment; rural community studies; economic sociology; and applied research methods. He is also interested in international development, social studies of science and technology, and political sociology. Currently he is engaged in research focusing on dynamics of economic and technological change in the dairy industry and their effects on farm families, rural communities, and the environment. He has also developed methods to track the spatial dimensions of rural and agricultural land use changes, and has worked with rural governments to develop locally appropriate land use and agricultural plans. Before going to Utah State University, he served as assistant professor of rural sociology and urban and regional planning at the University of Wisconsin-Madison. He also was codirector of the Program on Agricultural Technology Studies (a research and extension unit of the College of Agriculture), which examined the impacts of technological change and public policies on farm families in Wisconsin.

William A. Jury is a Distinguished Professor of Soil Physics in the Department of Environmental Sciences at University of California, Riverside. His principal research interests are measurement and modeling of organic and inorganic chemical movement and reactions in field soils; development and testing of organic chemical screening models; and characterization of volatilization losses of organic compounds. At present, Dr. Jury is conducting research in field measurement and modeling of preferential flow of chemicals, chemical transport at low water content, unstable flow of water in soil, global water management, and sequential reuse of agricultural drainage water. Dr. Jury received his PhD in physics from the University of Wisconsin.
