Modeling Evolutionary Dynamics of Lurking in Social Networks

Lurking is a complex user-behavioral phenomenon that occurs in all large-scale online communities and social networks. It generally refers to the behavior characterizing users that benefit from the information produced by others in the community without actively contributing back to the production of social content. The amount and evolution of lurkers may strongly affect an online social environment, therefore understanding the lurking dynamics and identifying strategies to curb this trend are relevant problems. In this regard, we introduce the Lurker Game, i.e., a model for analyzing the transitions from a lurking to a non-lurking (i.e., active) user role, and vice versa, in terms of evolutionary game theory. We evaluate the proposed Lurker Game by arranging agents on complex networks and analyzing the system evolution, seeking relations between the network topology and the final equilibrium of the game. Results suggest that the Lurker Game is suitable to model the lurking dynamics, showing how the adoption of rewarding mechanisms combined with the modeling of hypothetical heterogeneity of users' interests may lead users in an online community towards a cooperative behavior.Comment: 13 pages, 5 figures.

La recepción televisiva española en la era multipantalla

Este artículo estudia la recepción de la ficción televisiva española mediante una combinación de técnicas de análisis offline (cuestionarios y focus group) y online (comentarios en Internet). Los resultados del análisis offline revelan el carácter complementario y especializado de los dispositivos, aunque el análisis online no aporta evidencias sobre el impacto de las segundas pantallas en los procesos de socialización, ni sobre la construcción de identidad femenina.This article studies the reception of the Spanish television fiction, by combining offline analysis techniques (questionnaires and focus group) and online (analysis of comments on the Internet). The offline analysis reveals the complementary and specialized nature of the devices, but the online analyses do not provide evidence about the impact of the second screen in the socialization process, nor on the construction of feminine identity
