TL;DR: Stigma-reduction interventions should be targeted not only at thelevel of the individual but also at the level of the network, as directed and meaningful contact with people living with HIV may also reduce HIV-related stigma.

TL;DR: It is found that the partially observed shortest path does not necessarily give an inflated estimate of the length of the process path; in fact, partial observation may, counterintuitively, make the path seem shorter than it actually is.

TL;DR: In this paper, the authors developed and analyzed a tractable empirical model for strategic network formation that can be estimated with data from a single network at a single point in time, where the network formation is modeled as a sequential process where in each period a single randomly selected pair of agents has the opportunity to form a link.

TL;DR: The results imply high context modularity of human altruism and the development of intervention approaches including mindfulness meditation to increase social cooperation, especially among subjects with low baseline willingness to contribute.

TL;DR: A foundational study regarding the diffusion of innovation involved the adoption of tetracycline by doctors in four Midwestern communities in the 1950s, and it is not a coincidence that social scientists keep returning to this particular application of social network analysis.
