Universal behavior in a generalized model of contagion.

P. Dodds, D. Watts
Computer Science, Medicine
Physical review letters
29 March 2004

We introduce a general model of contagion which, by explicitly incorporating memory of past exposures to, for example, an infectious agent, rumor, or new product, includes the main features of existing contagion models and interpolates between them. Expand

Measuring the Happiness of Large-Scale Written Expression: Songs, Blogs, and Presidents

1 August 2010

The importance of quantifying the nature and intensity of emotional states at the level of populations is evident: we would like to know how, when, and why individuals feel as they do if we wish to better construct public policy, build more successful organizations, and, from a scientific perspective, more fully understand economic and social phenomena.

We conduct a detailed investigation of correlations between real-time expressions of individuals made across the United States and a wide range of emotional, geographic, demographic, and health characteristics. Expand

A generalized model of social and biological contagion.

P. Dodds, D. Watts
Psychology, Medicine
Journal of theoretical biology
21 February 2005

We present a model of contagion that unifies and generalizes existing models of the spread of social influences and microorganismal infections. Our model incorporates individual memory of exposure to… Expand
