In 1992 Robin Dunbar proposed a rough estimate of 150. But the "Dunbar's number" pretty much doubled in 1998, when Peter Killworth suggested a mean personal network size of 290. And in 2010 that number doubled again, as Matthew Salganik came up with 610 personal. So who says 1,200?... Read more »

Sage journal Body and Society vol 16, n. 4 is finally out! Pardon my enthusiasm, but this issue features my 30-page essay A History of Virulence: The Body and Computer Culture in the 1980s: a killer mix of hackerdom, virality and computer nostalgia that also happens to be IMHO one hell of a contribution to [...]...

So here it is, our little « manifesto for qualitative agent-based simulation » is finally out on the now Sage-published Bulletin of Sociological Methodology/Bulletin de Méthodologie Sociologique. It is just worth stressing the importance of this article in our present research: our effort has been to really provide a comprehensive framework for underdestanding what it means to [...]...

The current state of marriages is well below the social optimum, Swiss sociologists say. So they come up with a mathematical model to "reallocate partners" more efficiently via a shadowy "central agency". Next thing you know, divorces are reduced by 21%, mixed couples become illegal and right-wing nuts triumph...... Read more »

Pretty interesting article just published in JASSS. If you happen to be involved in agent-based simulation design, you know how bad your model can be screwed up by poor visualization. Here are some guidelines you might find useful.
