cooperation and emergence of Role Differentiation in the dynamics of social networks
arXiv: Physics and Society, 2007Co-Authors: Victor M Eguluz, Martin Zimmermann, Camilo J Celaconde, Maxi San MiguelAbstract:Models of cooperation grounded on social networks and on the ability of individuals to choose actions and partners aim to describe human social behavior. Extensive computer simulations of these models give important insight in the social mechanisms behind emerging collective behavior. We consider the entangled co-evolution of actions and social structure in a new version of a spatial Prisoner's Dilemma model that naturally gives way to a process of social Differentiation. Diverse social Roles emerge from the dynamics of the system: leaders -individuals getting a large payoff who are imitated by a considerable fraction of the population-, conformists -unsatisfied cooperative agents that keep cooperating-, and exploiters -Defectors with a payoff larger than the average one obtained by Cooperators. The dynamics generates a social network that can have the topology of a small world network. The network has a strong hierarchical structure in which the leaders play an essential Role sustaining a highly cooperative stable regime. The social structure is shown to be very sensitive to perturbations acting on the leaders. Such perturbations produce social crisis described as dynamical cascades that propagate through the network.

cooperation and the emergence of Role Differentiation in the dynamics of social networks
American Journal of Sociology, 2005Co-Authors: Victor M Eguiluz, Camilo J Celaconde, Martin G Zimmermann, Maxi San MiguelAbstract:By means of extensive computer simulations, the authors consider the entangled coevolution of actions and social structure in a new version of a spatial Prisoner’s Dilemma model that naturally gives way to a process of social Differentiation. Diverse social Roles emerge from the dynamics of the system: leaders are individuals getting a large payoff who are imitated by a considerable fraction of the population, conformists are unsatisfied cooperative agents that keep cooperating, and exploiters are defectors with a payoff larger than the average one obtained by cooperators. The dynamics generate a social network that can have the topology of a small world network. The network has a strong hierarchical structure in which the leaders play an essential Role in sustaining a highly cooperative stable regime. But disruptions affecting leaders produce social crises described as dynamical cascades that propagate through the network.

gender and job mobility in postsocialist china a longitudinal study of job changes in six coastal cities
Social Forces, 2007Co-Authors: Yang CaoAbstract:This study examines the gender differences in job mobility in urban China. Conceptualizing China's postsocialist transition as a multi-faceted process, we argue that the emergence of labor markets, gendered Role Differentiation within the family, and the state's declining involvement in promoting women's rights lead to widened gender gaps in job mobility. Event history analysis of data from six coastal cities finds that married women are less likely than their male counterparts to change jobs for career advancements, but are more likely to experience family-oriented job changes and involuntary terminations. The gender gaps in career-oriented job changes and involuntary terminations have also widened considerably during the reform period. We interpret these findings as the joint results of economic, socio-cultural and political processes.
