标题： Diffusion processes through social groups' dynamics

摘要： Axelrod模型描述了社会中由个体代理构成的一组文化特征的传播。 在社会背景下，个体对特定态度的选择也是社区、群体和政党的形成基础。 加入一个群体完全改变了单个代理的行为，他们开始根据社会身份行事。 群体作为单一实体相互作用，但仍然保持内部动态。 我们表明，在某些社会动态条件下，在文化传播过程中引入群体动态可以避免文化扁平化为单一实体，并保留文化态度的多样性。 我们还考虑了这种动态背景下的扩散过程，展示了信息以及创新在群体选择决定社会结构的情景下如何在人群中传播的条件。 显示英文摘要

摘要： Axelrod's model describes the dissemination of a set of cultural traits in a society constituted by individual agents. In a social context, nevertheless, individual choices toward a specific attitude are also at the basis of the formation of communities, groups and parties. The membership in a group changes completely the behavior of single agents who start acting according to a social identity. Groups act and interact among them as single entities, but still conserve an internal dynamics. We show that, under certain conditions of social dynamics, the introduction of group dynamics in a cultural dissemination process avoids the flattening of the culture into a single entity and preserves the multiplicity of cultural attitudes. We also considered diffusion processes on this dynamical background, showing the conditions under which information as well as innovation can spread through the population in a scenario where the groups' choices determine the social structure.
