Social media fingerprints of unemployment

Authors:Alejandro Llorente, Manuel García-Herránz, Manuel Cebrián and Esteban Moro Journal: PLoS ONE 10(5): e0128692 (2014) LINK 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 correctness in communication style. These behavioral metrics serve to build simple, interpretable, and cost-effective socio-economical predictors from these novel digital datasets. ...

From Seconds to Months: multi-scale dynamics of mobile telephone calls

Authors:Jari Saramaki, Esteban Moro Journal: Eur. Phys. J. B (2015) 88: 164 LINK | **arXiv Abstract: Big Data on electronic records of social interactions allow approaching human behaviour and sociality from a quantitative point of view with unforeseen statistical power. Mobile telephone Call Detail Records (CDRs), automatically collected by telecom operators for billing purposes, have proven especially fruitful for understanding one-to-one communication patterns as well as the dynamics of social networks that are reflected in such patterns. ...

Netmob 2015

I had the pleasure to organize last edition of Netmob at MIT Media Lab (together with Sandy Pentland, Vincent Blondel and Yves-Alexandre de Montjoye). Netmob is the primary conference in the analysis of those datasets in social, urban, societal and industrial problems. Netmob 2015 also hosted the final part of theD4D Challenge by Orange. They were 3 amazing days of applications and analysis of mobile phone datasets, preceded by one-day school and 3 days Hackathon. ...

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

Authors:Svetozar Nesic, Rodolfo Cuerno, and Esteban Moro Journal: Physical Review Letters 113, 180602 (2014) LINK Summary 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. Our results suggest that the macroscopic behaviour of the system is driven by the microscopic dynamics at its leading edge where number fluctuations are dominated by rare events. ...
