Book excerpt: Proposes situating theory and practice within contexts of power, recognizing both the ability of dominant groups to control and the potential for marginal communities to resist. Contributors from communication and anthropology explore the global and institutional structures within which agencies construct social problems and interventions, the discourse guiding the normative climate for conceiving and implementing projects, and the practice of strategic interventions for social change. Examines early and emerging models of development, power dynamics, ethnographic approaches, gender issues, and information technologies.
