| Social media are transforming global communication and coordination and provide unprecedented opportunities for studying socio-technical domains. Here we study global dynamical patterns of communication on Twitter across multiple scales. In particular, we study collective activities across geographical scales, from areas smaller than one square kilometer up to the global scale. Underlying the observed patterns is both the diurnal rotation of the earth, day and night, and the synchrony required for contingency of actions between individuals. We find that urban areas show a cyclic contraction and expansion that resembles heartbeats linked to social rather than natural cycles, mainly determined by daily routines of work, rest and recreation. Different urban areas have characteristic signatures of daily collective activities, varying the shape and location of peaks and valleys of activity. We show that the differences detected are consistent with a new emergent global synchrony that couples behavior in distant regions across the world, in part due to the communication power provided by social media. Although local synchrony is the major force that shapes the collective behavior in cities, a larger-scale synchronization is beginning to occur. | |
