移民是过去尤其是当今全球化文化的一个主要特征，了解移民如何塑造文化群体是文化传播理论实证应用的关键。这里开发的是一个移民同化模型，描述侨民文化的人口层面动态。利用 2009 年至 2010 年在汤加王国和汤加侨民社区收集的民族志数据，估计了模型的关键参数，并模拟了拟合模型，以描述汤加案例中的侨民文化动态。模拟中强调了新移民对人口层面的几种文化特征表达的相对贡献。结果表明，通过移民对汤加故乡作为保守文化来源的依赖是可变的且具有特定特征。对于同化率较高的性状，汤加新移民的贡献很大，而对于同化率较低的其他性状，汤加移民的影响则较小。讨论了解释特定性状同化率的初步假设。 (C) 2013 Elsevier Inc. 保留所有权利。
Migration is a major feature of past and especially today's globalized cultures, and understanding how migration shapes cultural groups is key to the empirical applications of cultural transmission theory. Developed here is a migration-assimilation model describing the population-level dynamics of diaspora culture. Using ethnographic data collected from 2009 to 2010 in the Kingdom of Tonga and a Tongan diaspora community, key parameters of the model were estimated and the fitted model simulated to describe diaspora cultural dynamics in the Tongan case. The relative contribution of recent migrants to the population-level expression of several cultural traits is highlighted in the simulation. Results show that the dependence on the Tongan homeland as a source of conservative culture through migration is variable and trait specific. For traits with higher assimilation rates, the contribution of recent Tongan migrants is substantial, while for other traits with lower assimilation rates, the influence of Tongan migrants is muted. Preliminary hypotheses to explain the trait-specific assimilation rates are discussed. (C) 2013 Elsevier Inc. All rights reserved.
