Educational institutions have the great challenge and the commitment not only to teach mathematics, science and language. They also must contribute to forming the new citizens. These new citizens should be critical and creative social actors that participate in the construction of better ways of coexistence. In this paper we propose educational strategies based on the use of Internet social net...

The use of social networks as a and educational environment emphasizes an approach to problems (bullying, cyberbullying, sexism, racism) that has emerged in today’s society. Social offer unique opportunity increase channels for communication socialization. aim this study is analyze the adolescents’ attitudes sports practice their extracurricular environment, it highlights importance didactic to...

Pattern formation is crucial for maintaining biodiversity and cooperation in nature and human society. We review recent works on the formation of spatial patterns in the framework of evolutionary games, involving rock-paper-scissors game and social dilemmas. The rock-paper-scissors game, as a basic paradigm for characterizing nonhierarchical cyclical competition in ecosystems, has been widely u...

This paper explores the optimal treatment of an infectious disease in a Susceptible-Infected-Susceptible model, where there are two strains of the disease and one strain is more infectious than the other. The strains are perfectly distinguishable, instantly diagnosed and equally costly in terms of social welfare. Treatment is equally costly and effective for both strains. Eradication is not pos...

We study the optimal subsidy on prevention against premature death in an economy composed of two-person households, where the survival of the spouse matters, either because of self-oriented coexistence concerns or because of altruism. Under a noncooperative household model, the laissezfaire prevention levels are shown to be lower than the first-best levels, to an extent that is increasing in se...

Questions of coexistence are deeply geographical. They are about the challenges of being-together-in-place. My experience of working at some of the difficult interfaces between Indigenous and non-Indigenous Australia – mining, infrastructure development, cross-cultural negotiations and self-government – has shown that there are few customs in common. Peoples’ co-occupation of both space and tim...

We review recent results on the dynamics of social networks which suggest that the interplay between the network formation process and volatility may lead to the occurrence of discontinuous phase transitions and phase coexistence in a large class of models. We then investigate the effects of negative links – links inhibiting local growth of the network – and of a geographical distribution of th...

Coevolutionary dynamics is investigated in chemical catalysis, biological evolution, social and economic systems. The dynamics of these systems can be analyzed within the unifying framework of evolutionary game theory. In this Letter, we show that even in well-mixed finite populations, where the dynamics is inherently stochastic, biodiversity is possible with three cyclic-dominant strategies. W...
