Long ties, the social ties that bridge different communities, are widely believed to play crucial
roles in spreading novel information in social networks. However, some existing network …

When people prefer to coordinate their behaviors with their friends--eg, choosing whether to
adopt a new technology, to protest against a government, to attend university--divisions …

How does network structure impact the speed and reach of social contagions? The current
view holds that random links facilitate “simple” contagion, but when agents require multiple …

Empirical social networks are characterized by a high degree of triadic closure (ie transitivity,
clustering), whereby network neighbors of the same individual are also likely to be directly …

The analysis of connection strengths and distances in the mobility network is pivotal for
delineating critical pathways, particularly in the context of epidemic propagation. Local …

The paper studies hospital networks where edges represent physicians' affiliated with
multiple hospitals. Using data from the universe of hospitals in the Brazilian healthcare …

How does social network structure amplify or stifle behavior diffusion? Existing theory
suggests that when social reinforcement makes the adoption of behavior more likely, it …

We highlight a trade-off between speed (the rate at which behaviours propagate in the
population) and resilience (the measure of initial adopters required for spreading) in models …

Ideas, behaviors, and opinions spread through social networks. If the probability of
spreading to a new individual is a nonlinear function of the fraction of the individuals' …

We analyze a game-theoretic abstraction of epidemic containment played on an undirected
graph $ G $: each player is associated with a node in $ G $ and can either acquire …
