Time allocation in social networks: correlation between social structure and human communication dynamics

Authors: Giovanna Miritello, Rubén Lara, and Esteban Moro Book: “Temporal Networks”, Springer, 2013. Series: Understanding Complex Systems. Holme, Petter; Saramaki, Jari (Eds.) [PDF]((http://arxiv.org/pdf/1305.3865v1.pdf) Summary Recent research has shown the deep impact of the dynamics of human interactions (or temporal social networks) on the spreading of information, opinion formation, etc. In general, the bursty nature of human interactions lowers the interaction between people to the extent that both the speed and reach of information diffusion are diminished. ...

Are you a social keeper or a social explorer?

In our last (just accepted) paper “Limited communication capacity unveils strategies for human interaction” [link] we have found that we humans have different social strategies when we communicate/interact with people. Specifically, the sociability of a person (the total number of contacts in a time interval) which is usually taken as the connectivity in the social network is actually the result of two different human features: Social capacity: the number of relationships humans can maintain opened and which is limited Social activity: the number of relationships human form and destroy as a consequence of their daily tasks, family, events, etc. ...

The predictability of consumer visitation patterns

Authors: Coco Krumme, Alejandro Llorente, Manuel Cebrian, Alex (“Sandy”) Pentland & Esteban Moro Journal: Sci. Rep. 3, 1645; (2013). LINK Abstract: We consider hundreds of thousands of individual economic transactions to ask: how predictable are consumers in their merchant visitation patterns? Our results suggest that, in the long-run, much of our seemingly elective activity is actually highly predictable. Notwithstanding a wide range of individual preferences, shoppers share regularities in how they visit merchant locations over time. ...

Limited communication capacity unveils strategies for human interaction

Authors: Giovanna Miritello, Rubén Lara, Manuel Cebrián and Esteban Moro Journal: Scientific Reports 3, 1950 (2013). LINK Abstract: Social connectivity is the key process that characterizes the structural properties of social networks and in turn processes such as navigation, influence or information diffusion. Since time, attention and cognition are inelastic resources, humans should have a predefined strategy to manage their social interactions over time. However, the limited observational length of existing human interaction datasets, together with the bursty nature of dyadic communications have hampered the observation of tie dynamics in social networks. ...

Limits of social mobilization

Authors: Alex Rutherford, Manuel Cebrian, Sohan Dsouza, Esteban Moro, Alex Pentland, and Iyad Rahwan Journal: PNAS 110 (16), 6281-6286 (2013) LINK Abstract: The Internet and social media have enabled the mobilization of large crowds to achieve time-critical feats, ranging from mapping crises in real time, to organizing mass rallies, to conducting search-and-rescue operations over large geographies. Despite significant success, selection bias may lead to inflated expectations of the efficacy of social mobilization for these tasks. ...
