In recent years, the literature has proposed different studies that combine the analysis of node-level attributes alongside topological information of the network. These proposals range from hierarchical clustering algorithms including relational constraints to communities in the context of Subgroup Discovery, and data-driven probabilistic methods on multilayer networks. While these methods...
How do employers, competing in the same markets, come to cooperate? In dyads, cooperation evolves if pairs of actors interact repeatedly, because it is mutually beneficial. Third actors support such dyadic cooperation by circulating information on actors' past behavior allowing actors to avoid non-cooperators. This paper focuses on the role of these third actors in cooperative networks. It...
Even though HIV incidence is falling globally, it remains relatively high amongst South African youth. Despite the availability of free and effective prevention and treatment methods, uptake remains low. Evidence suggests that sexual behaviour is strongly affected by social connections and interventions uptake can be improved by leveraging social networks. We therefore use social network data...
