One approach uses egocentric networks;, which provide a view of the network from the perspective of an actor in the network. The other approach uses whole networking which provide a view of the whole structure of the environment. * egocentric networks: 自我中心網絡。 Egocentric networks build a picture of a typical actor in any particular environment and show how many ties individual actors have to others, what types of ties they maintain, and what kind of information they give to and receive from others in their network.

    結構等值。根據與他人關係的相似聚集行動者。
  3. prominence, indicating who is “in charge,”
    卓越。指出誰是「帶頭負責的人」。
  4. range, indicating the extent of an actor’s network, and
    範圍。
