积分参数-平均场法
Paradox of integration - mean field approach
摘要:
最近,一个计算模型已经提出了社会融合,如描述的社会学术语彼得布劳。在这个模型中,演员们互相赞扬或批评,这些行为影响他们的社会地位,并引起消极或积极的情绪。那里也讨论了具有高社会地位的演员的自嘲策略的作用。在这里,我们开发了一个平均场的方法,其中主动和被动的角色(赞扬和被赞扬,等等)。是分离的。从友好到敌对情绪的相变已经被再现,类似于先前应用的纯计算方法。对于这两个阶段,我们调查的时间依赖的社会地位的分布。在那里,我们观察到一个扩散蔓延,这-经过一段短暂的时间-似乎是有限的从下面或从上面,这取决于阶段。因此,平均状态流动。
英文摘要:
Recently a computational model has been proposed of the social integration, as described in sociological terms by Peter Blau. In this model, actors praise or critique each other, and these actions influence their social status and raise negative or positive emotions. The role of a self-deprecating strategy of actors with high social status has also been discussed there. Here we develop a mean field approach, where the active and passive roles (praising and being praised, etc.) are decoupled. The phase transition from friendly to hostile emotions has been reproduced, similarly to the previously applied purely computational approach. For both phases, we investigate the time dependence of the distribution of social status. There we observe a diffusive spread, which - after some transient time - appears to be limited from below or from above, depending on the phase. As a consequence, the mean status flows.
