Graphing the English-speaking university curriculum

Here is a fascinating and ambitious "big data" project that aims at probing and mapping the structure of the disaggregated university curriculum in the United States and other English-speaking countries. The project is called the Open Syllabus Project and is hosted at Columbia University with a team including Joe Kraganis (project director), David McClure (Stanford …

The math of social networks

A social network is constituted by a number of units (nodes) that are connected to each other by a defined relationship -- for example, "x cites y", "x sends 5 email messages a week to y", "x and y belong to an organization in common." There are a few wrinkles -- the units may be …

Social networks as aggregators

We think of social phenomena as "relational" in some important respect. Individuals contribute to social outcomes through structured and dynamic relationships with other individuals. So outcomes are not just heaps of aggregated individual behavior; rather, they are the filigreed result of interlinked, coordinated, competitive and sometimes unintended actions of people who have intentional and structural …

The public sphere

The current issue of Social Science History is devoted to a series of articles in honor of Charles Tilly (link), around the general theme of the "public sphere" (the theme of the Social Science History Association annual meeting in 2007). Tilly was an active presence in the Social Science History Association, and this issue recognizes Tilly's …

Spatial patterns in the US

Here are four interesting graphics representing different kinds of activity in the United States.  The top panel represents population concentrations across the United State.  The second image is air traffic across the country, and the third image is internet traffic across the country.  The final image is a photograph of the United States from space …

Are social networks fundamental?

There are several natural starting points when we begin thinking seriously about the social world and how it works. For example, we can begin with individual agents and try to understand social patterns as the expression of common features of reasoning and motivation by stylized agents. This is roughly the strategy underway in rational choice …

Microstructure of strife

Let's work backwards in thinking about sustained inter-group violence, and begin by considering some of the street-level incidents that constitute a period of violence against or between groups. What factors are necessary to the occurrence of inter-group violence in a region? And how can an understanding of these factors contribute to better strategies of conflict …

Social entrepreneurs

Social entrepreneurs are people who want to bring about non-routine projects, collaborations, or organizations where they didn't previously exist in order to solve a perceived social problem. This is very different from working within an existing organization and using its official resources to bring about a particular result. An example might be a community activist …

The reality of society

We sometimes speak of "global society", we refer to "French society"; and we also think of face-to-face organizations and neighborhoods as small societies or social groups. There is an important conceptual point in the background in these common ways of speaking: what are the features of interaction or relationship that must obtain in order for …

Are there discrete social mechanisms?

McAdam, Tarrow and Tilly direct our attention to the level of the concrete social mechanisms that recur in many instances of social contention (Dynamics of Contention). They specifically refer to escalation, radicalization, brokerage, and repression as examples of social mechanisms that produce the same effects in the same circumstances, and that concatenate into historical processes …
