居住隔离与文化传播：阿克塞尔罗德-谢林模型
Residential segregation and cultural dissemination: An Axelrod-Schelling model
摘要：
在阿克塞尔罗德的文化传播模型，我们认为流动性的文化代理商通过引入密度的空站点和代理商在不同的邻居可以移动到他们的可能性，如果他们的平均文化相似性与邻里低于一定的阈值。而对于较低的值的空站点的密度的流动性增强了收敛到一个全球性的文化，它的足够高的值的动态可以导致不同文化的断开域的共存。在这种制度下，最初的文化多样性的增加反而增加了向主导文化的趋同。多样性的进一步增加导致主导文化分裂成不同的领域，在形式和数量上永远在变化，这是文化少数群体无休止的侵蚀活动的结果。
英文摘要：
In the Axelrod's model of cultural dissemination, we consider mobility of cultural agents through the introduction of a density of empty sites and the possibility that agents in a dissimilar neighborhood can move to them if their mean cultural similarity with the neighborhood is below some threshold. While for low values of the density of empty sites the mobility enhances the convergence to a global culture, for high enough values of it the dynamics can lead to the coexistence of disconnected domains of different cultures. In this regime, the increase of initial cultural diversity paradoxically increases the convergence to a dominant culture. Further increase of diversity leads to fragmentation of the dominant culture into domains, forever changing in shape and number, as an effect of the never ending eroding activity of cultural minorities.
