James Moody to Doug White email: I've put together a social-science coauthorship network (based on all papers listed in Sociological Abstracts, 1965-1999).› The graph has ~128,000 nodes, ~70,000 of which are in the largest component, and ~30,000 in the largest bicomponent.› If you're interested, I've put together a fun visualization of the largest bicomponent.› The problem w. visualizing a network of this size is that the nodes stack up on top of each other, making it impossible to see the underlying structure. In this plot, I use PAJEK to get an optimal 2d layout (took almost a week to finish), then identify the number of nodes in a particular (small) xy space, which leads to the contour plot in the second panel ("density" in this plot is the number of nodes in any cell). The plot is at: http://www.soc.sbs.ohio-state.edu/jwm/bicomp_paj_cont.pdf (file is ~500kb)
In the paper that's forming from this work, I'm contrasting different models of the underlying structure (Watt's small world, Barabasi's Scale-Free nets, and our distributed cohesion model), to see how they compare, and relating this structure to ideas about "invisible colleges".› I hope to have a draft by the end of next month, if so I'll send it your way.
What else?› I just submitted a paper to AJS on weapon carrying among adolescents.› Turns out, that students who are not members of› the largest bicomponent are much more likely (Odds Ratio of about 2) to carry weapons to school, which I interpret as a lack-of-socialization effect stemming from not being part of the substantive community.› Just sent that out the door, so may be awhile before anything comes of it.
