在阿克塞尔罗德的模型中,大众传媒破坏了文化同质性的稳定

Mass media destabilizes the cultural homogeneous regime in Axelrod's model

Lucas R. Peres, José F. Fontanari

摘要:

阿克塞尔罗德的文化传播或社会影响模型的一个重要特征是出现了许多多元文化的吸收国家,尽管事实上,指定代理人互动的地方规则明确旨在减少代理人之间的文化差异。在这里,我们重新审视在阿克塞尔罗德模型的规则中引入外部全球互动--大众媒体--的问题:除了最近的邻居之外,每个代理人都有一定的概率$p$与虚拟邻居互动,其文化特征从一开始就固定了。最令人惊讶的是,这种表面上的文化差异实际上增加了人口的文化多样性。我们表明,与文献中先前的声明相反,即使是一个非常小的值$p$的$p$是足够的稳定非常大的晶格尺寸的均匀制度。

英文摘要:

An important feature of Axelrod's model for culture dissemination or social influence is the emergence of many multicultural absorbing states, despite the fact that the local rules that specify the agents interactions are explicitly designed to decrease the cultural differences between agents. Here we re-examine the problem of introducing an external, global interaction -- the mass media -- in the rules of Axelrod's model: in addition to their nearest-neighbors, each agent has a certain probability $p$ to interact with a virtual neighbor whose cultural features are fixed from the outset. Most surprisingly, this apparently homogenizing effect actually increases the cultural diversity of the population. We show that, contrary to previous claims in the literature, even a vanishingly small value of $p$ is sufficient to destabilize the homogeneous regime for very large lattice sizes.
