Kinetics of Social Contagion

2015 - Zhongyuan Ruan, Gerardo Iniguez, Marton Karsai & Janos Kertesz.

Abstract: Diffusion of information, behavioral patterns or innovations follows diverse pathways depending on a number of conditions, including the structure of the underlying social network, the sensitivity to peer pressure and the influence of media. Here we study analytically and by simulations a general model that incorporates threshold mechanism capturing sensitivity to peer pressure, the effect of `immune' nodes who never adopt, and a perpetual flow of external information. While any constant, non-zero rate of dynamically-introduced spontaneous adopters leads to global spreading, the kinetics by which the asymptotic state is approached shows rich behavior. In particular we find that, as a function of the immune node density, there is a transition from fast to slow spreading governed by entirely different mechanisms. This transition happens below the percolation threshold of network fragmentation, and has its origin in the competition between cascading behavior induced by adopters and blocking due to immune nodes. This change is accompanied by a percolation transition of the induced clusters.

Jun 22, 2021 The graduate school "Confinement-Controlled Chemistry" is looking for top-class graduate students with an interest in exploring the influence of geometrical confinement on reactions. Our graduate school offers a three-year-program, starting October 1st 2021 latest (preferably earlier), that combines cutting-edge research with a structured curriculum (in English) of lectures, colloquia and workshops in the fields of theory, spectroscopy, synthesis, and surface science. The program also comprises the opportunity for an integrated three-month research stay, preferably at the University of California.
