social network

Quick Reference

Patterns of interpersonal relationships among individuals based on face-to-face interaction and/or mediated communication. The concept of social networks was introduced by Radcliffe-Brown in 1940. Such networks (based on links rather than individuals) emerge from interaction and can cut across and influence institutions; they can also shape individual behaviour. In sociology and anthropology, kinship and friendship networks have been a key focus; the advent of the internet has stimulated the concept of network societies.
