In social networks, individuals have relationships with their neighbor nodes (acquaintance contacts) and also randomly contact other nodes without direct links (stranger contacts). However, these two types of contact patterns are rarely considered together. In this paper, we propose a modified SIS (Susceptible-Infected-Susceptible) model in which a node not only contacts neighbor nodes but also...

How is social etiquette performed when offline interpersonal interactions are mediated online? Sixty semi-structured interviews with WeChat users, China's most popular media platform, show that the app's technical designs facilitated a set of online rules which reproduced those acquaintance communities.

Social embeddedness always plays important role in facilitating agricultural technology diffusion. However, China, dramatic changes have occurred the social of rural households transition from ‘acquaintance society’ to ‘semi-acquaintance society’. Could this be reason for debate over embeddedness? What are differences between farmers with different land scales? Based on survey data 583 Zhejiang...

In this short note, we prove a conjecture of Benjamini, Shinkar, and Tsur on the acquaintance time AC(G) of a random graph G ∈ G(n, p). It is shown that asymptotically almost surely AC(G) = O(log n/p) for G ∈ G(n, p), provided that pn−log n−log log n→∞ (that is, above the threshold for Hamiltonicity). Moreover, we show a matching lower bound for dense random graphs, which also implies that asym...
