Using network visualization and the study of the dynamics of marriage choices, Network Analysis and Ethnographic Problems expands the theory of social practice to show how changes in the structure of a society's kinship network affect the development of social cohesion over time. Using the genealogical networks of a Turkish nomad clan, authors Douglas White and Ulla Johansen explore how changes in network cohesion are revealed to be indicative of key processes of social change. This approach alters in fundamental ways the anthropological concepts of social structure, organizational dynamics, social cohesion, marriage strategies, as well as the study of community politics within the dynamics of ongoing personal interaction.
