The evolution of cooperation and communication in communities of individuals is a puzzling problem for a wide range of scientific disciplines, ranging from evolutionary theory to the theory and application of multi-agent systems. A key issue is to understand the factors that affect collaboration and communication evolution. To address this problem, here we choose the environmental risk as a com...

The occurrence of cooperation poses a problem for the biological and social sciences. However, many aspects of the biological and social science literatures on this subject have developed relatively independently, with a lack of interaction. This has led to a number of misunderstandings with regard to how natural selection operates and the conditions under which cooperation can be favoured. Our...

This article reviews the trajectory of international cooperation in the light of the adjustments made at the leading international conferences on the topic (Buenos Aires, 1978; Rome, 2003; Paris, 2005; Accra, 2008; and Busan, 2011). This article aligns these new approaches with the practices Fiocruz has adopted, such as “structural cooperation in health,” namely a diplomatic approach that inclu...

Most evolutionary algorithms concerned with a memory of evolution aim at memorizing and reusing the recipes of past successes (e.g. fruitful operators or fruitful mutation directions). The scheme proposed here follows the opposite track, and memorizes the past failures of evolution (unnt oospring) through a virtual individual termed the virtual loser. The underlying metaphor is that oospring sh...

The theoretical description of the evolution of cooperation presented by Bergstrom based on assortative matching with partner choice allows to model the population dynamics in a game of Nonrepetitive Prisoners Dilemma. In this paper we present a short analysis of asymmetric effects brought into the game by self knowledge of the participants, that is the knowledge of one's own strategy. Within t...

Recent experimental results with humans involved in social dilemma games suggest that cooperation may be a contagious phenomenon and that the selection pressure operating on evolutionary dynamics (i.e., mimicry) is relatively weak. I propose an evolutionary dynamics model that links these experimental findings and evolution of cooperation. By assuming a small fraction of (imperfect) zealous coo...

Most readers of Perspectives on Science and Christian Faith are acquainted with the terms “young-earth creation,” “old-earth creation,” and “theistic evolution.”1 These reflect the fact that, among Christians in general and within the American Scientific Affiliation in particular, there is considerable disagreement on how to relate the biblical and scientific data on origins. Some feel that the...

The observations will be used to validate existing models and to develop new models for ripple geometry as a function of forcing hydrodynamics and seabed characteristics. The observations will also have a smaller focus on small scale sediment transport processes over ripples and larger scale wave field variability over spatially variable ripples. The small scale sediment transport process obser...

Cooperation plays an essential role in the evolution of social species, chief among all in humans. In this paper, we study the effects of compassion on the evolution of cooperation in spatial social dilemmas by introducing a payoff redistribution mechanism. In particular, a player whose payoff is larger than the average in its neighborhood will share some it with its comparatively poor neighbor...

at the moment, 14 european talent centres belong to the recently formed european talent support network, which, in the long run, can bring new dimensions to pan-european cooperation in supporting young talented people all over europe.  exchange and adaptation of best practices, spread and application of scientific results, possibilities of mutual visits of young talents, their teachers, mentors...
