Abstract
We investigate the problem of cross-cultural interactions through mass media in a model where two populations of social agents, each with its own internal dynamics, get information about each other through reciprocal global interactions. As the agent dynamics, we employ Axelrod's model for social influence. The global interaction fields correspond to the statistical mode of the states of the agents and represent mass media messages on the cultural trend originating in each population. Several phases are found in the collective behavior of either population depending on parameter values: two homogeneous phases, one having the state of the global field acting on that population, and the other consisting of a state different from that reached by the applied global field; and a disordered phase. In addition, the system displays nontrivial effects: (i) the emergence of a largest minority group of appreciable size sharing a state different from that of the applied global field; (ii) the appearance of localized ordered states for some values of parameters when the entire system is observed, consisting of one population in a homogeneous state and the other in a disordered state. This last situation can be considered as a social analogue to a chimera state arising in globally coupled populations of oscillators.
Highlights
The study of cross-cultural experiences through mass-mediated contact is a topic of much interest in the Social Sciences [1,2,3,4,5]
The collective behavior of either of the two subsets coupled through their reciprocal global fields can be characterized by four phases on the space of parameters (B,q), as shown in Fig. 5 for subset a: (I) a homogeneous, ordered phase, for which Sa1*1 and P1a(Mb)~1; (II) an ordered phase in a state orthogonal to the applied global field, such that Sa1*1 and P1a(Mb)v1; (III) a disordered phase for qwqc, for which Sa1^0; and (IV) a partially ordered phase, where Sa2w0 and Sa1zSa2&1, P1a(Mb)~1, characterized by the emergence of a second largest domain ordered in a state different from field Mb
We have investigated the collective behavior of a system consisting of two populations of social agents, mutually coupled through global fields, as a model for cross-cultural interactions via mass media
Summary
The study of cross-cultural experiences through mass-mediated contact is a topic of much interest in the Social Sciences [1,2,3,4,5].
