同质化、文化漂移与文化群体的共进化
Homophily, Cultural Drift and the Co-Evolution of Cultural Groups
摘要：
在文化分化的研究中，同质性和影响力的联合机制已经能够解释不同的文化群体是如何形成的。虽然这些机制通常导致文化趋同，但异质性的增加可以使它们产生全球多样性。然而，事实证明，这种新兴的文化多样性在“文化漂移”面前是不稳定的-小错误或创新，使文化从内部发生变化。我们开发了一个文化分化模型，将传统的同质性和影响力机制与第三种机制“网络同质性”相结合，其中网络结构与文化互动共同进化。我们发现，如果社会关系被允许改变文化的影响，异质性和文化多样性之间的复杂关系被揭示，在增加异质性可以减少文化群体的形成，同时增加社会联系。我们的研究结果表明，在某些区域的参数空间，这些共同进化的动态可以导致文化多样性的模式，是稳定的文化漂移的存在。
英文摘要：
In studies of cultural differentiation, the joint mechanisms of homophily and influence have been able to explain how distinct cultural groups can form. While these mechanisms normally lead to cultural convergence, increased levels of heterogeneity can allow them to produce global diversity. However, this emergent cultural diversity has proven to be unstable in the face of "cultural drift"- small errors or innovations that allow cultures to change from within. We develop a model of cultural differentiation that combines the traditional mechanisms of homophily and influence with a third mechanism of 2network homophily", in which network structure co-evolves with cultural interaction. We show that if social ties are allowed to change with cultural influence, a complex relationship between heterogeneity and cultural diversity is revealed, in which increased heterogeneity can reduce cultural group formation while simultaneously increasing social connectedness. Our results show that in certain regions of the parameter space these co-evolutionary dynamics can lead to patterns of cultural diversity that are stable in the presence of cultural drift.
