  1. Social Network AnalysisandElectronic Interaction Wireless Technology, New Applications and Social Interaction Clayton Childress Sociology UCSB

  2. Social Network Analysis: A Background • Term Coined by J.A. Barnes in 1954 • Sociometrics • Harvard School • The Manchester School

  3. Early Uses • Small Groups - The Bank Wiring Room (Warner & Mayo) • Larger Networks - The Strength of Weak Ties (Granovetter) - The Rule of 150 (Dunbar) - Small World Phenomenon (Milgram)

  4. Common Uses • Diffusion of Ideas and Diseases • Social Influence • Social Support • Overt and Covert Organizational Structure • Marketing and Management • Social Movements

  5. Reading a Social Networks Graph

  6. Things to Remember When Looking at Social Network Data and Graphs • The structure, not the individual, is the unit of analysis • Many network studies only provide a snapshot view • What are the limits in the breadth of the network measured? • How are nodes and ties being established? • Are the measurements chosen sweeping anything under the rug?
