“…In addition to above heterogeneity we applied with Pajot, percolation theory to address the problem of coexistence of opposite collective opinions, like for instance with the feeling of safeness, within the same social frame. The possibility of superposition of simultaneous percolation from two different species was analyzed and shown to provide an explanation to such a paradoxical social phenomenon [59].…”

We review a series of models of sociophysics introduced by Galam and Galam et al in the last 25 years. The models are divided in five different classes, which deal respectively with democratic voting in bottom up hierarchical systems, decision making, fragmentation versus coalitions, terrorism and opinion dynamics. For each class the connexion to the original physical model and technics are outlined underlining both the similarities and the differences. Emphasis is put on the numerous novel and counterintuitive results obtained with respect to the associated social and political framework. Using these models several major real political events were successfully predicted including the victory of the French extreme right party in the 2000 first round of French presidential elections, the voting at fifty -fifty in several democratic countries (Germany, Italy, Mexico), and the victory of the no to the 2005 French referendum on the European constitution. The perspectives and the challenges to make sociophysics a predictive solid field of science are discussed.

“…For example, there is considerable current interest in opinion models [16], among which we cite the the Sznajd model [17], the voter model [18], the naming game [19,20] and Galam models [21,22]. But the influence of more than one network has gathered less attention [23].…”

Abstract. -Many real systems are made of strongly interacting networks, with profound consequences on their dynamics. Here, we consider the case of two interacting social networks and, in the context of a simple model, we address the case of political elections. Each network represents a competing party and every agent, on the election day, can choose to be either active in one of the two networks (vote for the corresponding party) or to be inactive in both (not vote). The opinion dynamics during the election campaign is described through a simulated annealing algorithm. We find that for a large region of the parameter space the result of the competition between the two parties allows for the existence of pluralism in the society, where both parties have a finite share of the votes. The central result is that a densely connected social network is key for the final victory of a party. However, small committed minorities can play a crucial role, and even reverse the election outcome.Introduction. -Interacting and interdependent networks have recently attracted great attention [1][2][3][4][5][6][7][8][9][10]. Here, the function of a node in one network depends on the operational level of the nodes it is dependent on in the other networks. Investigated examples range from infrastructure networks as the power-grid and the Internet [1] to interacting biological networks in physiology [10]. Understanding how critical phenomena [11,12] are affected by the presence of interactions or interdependent networks is crucial to control and monitor the dynamics of and on complex systems. In this context it was shown that interdependent networks are more fragile than single networks, and that the percolation transitions can be first order [1].

Adaptation of cultural norms after merger and acquisition based on the heterogeneous agent-based relative-agreement model

The subject of norm formation and diffusion has gained lots of attention in social science and organizational science in the last decade. This paper explores how public dissenters in acquired firms can affect success or failure of merger and acquisition (M&A). In the classical relative-agreement model, all individuals observe their neighbors' behavior and update their own opinion and behavior following the same rule. This paper proposes a new heterogeneous relative-agreement model where individuals update their behavior following different rules after M&A. Simulation experiments show that the time shortly after acquisition is a key period to guide the acculturation in a way consistent with the intent of the acquiring firm, and that the risk of cultural norm reversing after acquisition is influenced by several important factors. Some suggestions for guiding the acculturation process after M&A are also provided.
