  5. Time Slices Define a Social Network Network Dynamics and Simulation Science Laboratory

  6. Decreasing fidelity, but invariant degree distribution, in social networks (above) affects disease dynamics (below)

  7. Basic Structural Properties of Portland Social Network * Degree distribution of the (temporal) people-ppl. graph Degree distributions of the bipartite graph Clustering Coefficient * Nature, 13 May 2004

  8. Scaling Laws for Structural Measures* Shattering by high degree people Degree Distribution Cumulative point overlap ratios * ACM SIAM SODA 2004 and DIMACS Issue on Epidemiology
