  • Basic text: Social Networks: An advanced introduction for sociologists and everybody else, by Jeroen Bruggeman. He synthesizes new approaches in network analysis in a lively test that makes the current approaches and materials accessible both at the introductory level and the advanced level

    Related themes for the seminar:

  • Understanding Generative Models for networks, expanding on chapters 3 and 4, including the generative random models, small-word, scale-free and the more realistic social-circles generative network models reviewed in the pdf the social circles generative model 2006 publication
    Networks and Hierarchies provides some foundational model for networks and processes widely useful in network studies.(but the q-exponential example requires correction.
  • Issues and new methods for community-finding, roles, and cohesion

  • Use of Pajek, R from Pajek, Spss, Excel optimizer, MLE estimation, Exponential random graphs (see below), and simulations from generating functions. We meet in a computer lab to facilitate use of software where appropriate. Here are instructions For Rcmdr, the R GUI if you prefer menu-driven R. Pajek to R: Vectors and Matrices
    Pajek How To? How to.PDF, and SNA (see for example The interaction of size and density with graph-level indices; Anderson, Butts, and Carley 1999)
  • Analytic methods and results for network and social dynamics
  • students will present chapters and readings chosen from references below (references on-line suited for a variety of graduate student interests), do exercises from the text, use software in the lab, work on and present a project of their choice


    The UCI Social Network Research Group meets Thursdays an hour after this seminar ends (3-4:00).

    Data and articles on large networks: finding communities in large networks, finding monopolies, origins of capitalism, global and regional trade networks (city and state,and their longitudinal dynamics), networks of civilizations, modeling continent level social networks, cultural diffusion and demography (Australia), supply networks of industrial districts, inter-industry networks, the worldwide biotech industry network, epistemic communities in the sciences, modeling central asian/mid eastern polities based on their kinship and systems, modeling countrywide social class systems as networks, the Bell Labs phone call network (broken down by businesses and residences--63 million calls in one day: what are the network properties?), social movements, and large networks from all over the planet and all the disciplines. All fascinating materials relevant to Sociology, Economics, PoliSci, ICS, MBS, Demography, Anthro, Statistics, History, Business School and marketing students. We will be using excel, pajek and R (see installation, FAQ, its six pdf manuals in the R help menu, and Carter's CRAN pages) as analytic tools, and reading from the new literature on large networks. The course links reach out to all kinds of potential projects, including the European Union project on social and network scaling, the Santa Fe Institute project on civilizations, the International Society/Conferences on Complexity Systems and its living roadmap for complexity sciences, the complexity network in Korea, etc. In addition, signing on to the 1.33 credit colloquium Soc Sci 240B for the Human Sciences and Complexity Videocolloquia provides access to top speakers every two weeks or so. The concise new on-line book, Social Networks Basics for Sociologists and everyone else by Jeroen Bruggeman, covers the latest advances in network analysis.

    Week 4: Historical Dynamics A good starting point for global historical network dynamics would be the Peter Turchin book, 2003, Historical Dynamics: Why States Rise and Fall. Princeton: Princeton University Press, in the series Princeton Studies in Complexity. It has chaps 2-4 on Geopolitics; Collective Solidarity; and Metaethnic frontier theory and a very strong dynamical methodology (see below, NLTSM, and the software download. There is a less formal presentation of these ideas and case studies in Peter Turchin. 2006. War and Peace and War: The Life Cycles of Imperial Nations $18, used for $10. This required reading is the best education in historical dynamics and contemporary issues, emphasizing culture and cooperation, that you will ever get, and it summarizes in a nontechnical way the principles of Turchin's published theories and analysis of culture and historical evolution.

    - REGE (drw REGE, REGD, some other variants describes in a paper soon to be submitted to The journal of mathematical sociology.
    - A function that computes distance in terms of structural equivalence (several options).
    - Generalized blockmodeling (binary (Doriean, Batagelj, Ferljgoj), valued (my), homogeneity(my), implicit (ideas by Batagelj, Ferljgoj))
    - A ploting function for (a partitioned) matrix.

    On the applied side, we can start the network analysis studies with the problem of network position of different sectors in national economies in Europe, for which I have data on six countries five time periods with comparable input-output data. See regular equivalence analysis. That should give some understanding of the dynamics of productive economies; the commonalities or differences in their network topologies; may also lead to a joint publication with a team of researchers in Germany; and we can use the classical regular equivalence program for positional analysis that Dave Smith and used in our global dynamics analysis, 1965-1980 for which the following readings would be in order:
