We might imagine that someone “central” to the network is someone who holds some sort of important, advantaged position in the network. 7 Social Capital: Network Structure and Social Outcomes.5.1 The Foundations of Network Connectivity.4.7 Problems in Understanding Homophily.4.6 Network Composition-Homophily Measures.2.11 Weighted Ties as a Measure of Strength.2.5 Anti-Symmetric Ties and Tree Graphs.2.4 Asymmetric Relations and Directed Graphs. ![]() 2.3 Symmetric Relations and Undirected Graphs.2.2 The Building Blocks of Graphs: Edges and Nodes.2.1 Social Network Analysis: From Relationships to Graphs.1.3 The Two Faces of Social Network Analysis.
