On Universality in Human Correspondence Activity (2009)
Malmgren, R. Dean, Stouffer, Daniel B., Amaral, Luis A. Nunes
Identifying and modeling patterns of human activity has important ramifications in applications ranging from predicting disease spread to optimizing resource allocation. Because of its relevance and...
Poissonian bursts in e-mail correspondence (2009)
Anteneodo, C., Malmgren, R. Dean, Chialvo, D. R.
Recent work has shown that the distribution of inter-event times for e-mail communication exhibits a heavy tail which is statistically consistent with a cascading Poisson process. In this work we...
Characterizing Individual Communication Patterns (2009)
Malmgren, R. Dean, Hofman, Jake M., Amaral, Luis A. N., Watts, Duncan J.
The increasing availability of electronic communication data, such as that arising from e-mail exchange, presents social and information scientists with new possibilities for characterizing...
A Poissonian explanation for heavy-tails in e-mail communication (2009)
Malmgren, R. Dean, Stouffer, Daniel B., Motter, Adilson E., Amaral, Luis A. N.
Patterns of deliberate human activity and behavior are of utmost importance in areas as diverse as disease spread, resource allocation, and emergency response. Because of its widespread availability...
Log-normal statistics in e-mail communication patterns (2006)
Stouffer, Daniel B., Malmgren, R. Dean, Amaral, Luis A. N.
Following up on Barabasi's recent letter to Nature [435, 207--211 (2005)], we systematically investigate the time series of e-mail usage for 3,188 users at a university. We focus on two quantities...
Comment on Barabasi, Nature 435, 207 (2005) (2005)
Stouffer, Daniel B., Malmgren, R. Dean, Amaral, Luis A. N.
In a recent letter, Barabasi claims that the dynamics of a number of human activities are scale-free [1]. He specifically reports that the probability distribution of time intervals tau between...
