Social media fingerprints of unemployment

Alejandro Llorente, Manuel García-Herránz, Manuel Cebrián and Esteban Moro (2014), arXiV1411.3140 [PDF] Summary: Publicly available social media data can be used to quantify deviations from typical patterns of behavior and uncover how these deviations signal the socio-economical status of regions. Using data from geolocalized Twitter messages, we find that unemployment is correlated with technology adoption, daily activity, diversity in mobility patterns, and...

Macroscopic Response to Microscopic Intrinsic Noise in Three-Dimensional Fisher Fronts

Svetozar Nesic, Rodolfo Cuerno, and Esteban Moro Physical Review Letters 113, 180602 (2014) [APS] Abstract We study the dynamics of three-dimensional Fisher fronts in the presence of density fluctuations. To this end we simulate the Fisher equation subject to stochastic internal noise, and study how the front moves and roughens as a function of the number of particles in the system, N....

Performance of Social Network Sensors During Hurricane Sandy

Yury Kryvasheyeu, Haohui Chen, Esteban Moro, Pascal Van Hentenryck, Manuel Cebrian (2013) [arxiv] Abstract Information flow during catastrophic events is a critical aspect of disaster management. Modern communication platforms, in particular online social networks, provide an opportunity to study such flow, and a mean to derive early-warning sensors, improving emergency preparedness and response. Performance of the social networks sensor method,...
