AVVISO di SEMINARIO
The Mathematics of Human Contact
Prof. Enrico Scalas University of Sussex
We present a statistical analysis of high-resolution contact pattern data within primary and secondary schools as collected by the SocioPatterns collaboration. Students are graphically represented as nodes in a temporally evolving network, in which links represent proximity or interaction between students. We focused on link- and node-level statistics, such as the on- and off-durations of links as well as the activity potential of nodes and links. Parametric models are fitted to the on- and off-durations of links, inter-event times and node activity potentials and, based on these, we propose a number of theoretical models that are able to reproduce the collected data within varying levels of accuracy. By doing so, we aim to identify the minimal network-level properties that are needed to closely match the real-world data, with the aim of combining this contact pattern model with epidemic models in future work. This is joint work with Stephen Ashton, Nicos Georgiou and Istvan Zoltan Kiss. Relevant preprints: https://arxiv.org/abs/1502.04072 https://arxiv.org/abs/1802.07261
