Multiplexity Matters

Multiplex social ties are social relationships formed via engagement in multiple social roles, exchange, events, and organizations. How do network layers (e.g., family, friendship, advice, affiliation, neighborhood, etc.) strengthen or interfere one another both in magnitude and in topological structure? What are the multiplex structures that facilitate (or retard) a cascade of a targeted health intervention in a community? In this talk, I will challenge the uniplex approach in big-data network analysis that is often hardly generalizable beyond the specific type of social interaction under consideration. I anchor my research with an extensive analysis of complete networks of nearly 30,000 participants in 176 villages in rural Honduras based on 16 name generators. Results show that there is great structural heterogeneity across networks elicited by different name generators, and that different types of social ties play distinct roles in the social life of the communities in influencing both network structure and health knowledge distribution.
