A network is a representation of connections among a set of nodes and edges.

The concept of social capital describes the benefits individuals derive from their social relationships and interactions: resources such as emotional support, exposure to diverse ideas, and access to non-redundant information. Social capital is embedded in the structure of social networks and the location of individuals within these structures (Burt, 2005). Because social network sites (SNSs) have the potential to reshape social networks and lower the costs of communicating with (and thus contributing to and extracting benefits from) this social network, SNS use may have social capital implications. This study is among the first to explore the relationship between social capital and specific communication practices on the most popular SNS among US undergraduates, Facebook.

We used logistic regression and random forest to predict user behaviors on a Chinese social network, Weibo.

The rapid growth of Uber and analogous platform companies has led to considerable scholarly interest in the phenomenon of platform labor. Scholars have taken two main approaches to explaining outcomes for platform work—precarity, which focuses on employment classification and insecure labor, and technological control via algorithms. Both predict that workers will have relatively common experiences.

There are two complementary perspectives on the importance of friendship maintenance, particularly in the U.S. college-aged population. First, relationships help generate social capital (Lin,1999) and are important components of psychosocial development for emerging adults (Sullivan, 1953). For the college-age populations, sites like Facebook may play a vital role in maintaining relationships that would otherwise be lost as these individuals move from the geographically bounded networks of their hometown. Second, there is also growing evidence that Internet use in general, and social network sites like Facebook in particular, may be associated with a person's sense of self-worth and other measures of psychosocial development, although the positive or negative contributions of Internet use to psychological well-being are hotly debated (Kraut, Patterson, Lundmark, Kiesler, Mukhopadhyay, & Scherlis, 1998; Kraut, Kiesler, Boneva, Cummings, Helgeson, & Crawford, 2002; Shaw & Gant, 2002; Valkenburg et al., 2006).
