MIGRATION, CONTRACEPTION, AND SOCIAL NETWORKS

这项拟议的研究利用在泰国Nang Rong收集的一套独特的社会调查，探讨了移民、避孕选择和社会网络之间的相互关系。社会网络，即个人、家庭和社区之间的一系列关系，是信息传播和更普遍的扩散过程的关键。它们也是理解规范、规范压力和一致性的基础。拟议的研究将通过调查来阐明这些机制：(a)原籍地的社会网络以及发现和成功采访外迁者的可能性；(b)来源国的社会网络以及来源国与目的地国之间的联系对汇款流量的数量、构成和方向的影响；(c)社会网络地位对避孕选择的影响。将以亲属为基础的网络与以经济援助和交换为基础的网络以及在多个分析层次上的网络进行比较，将有可能得出一些关于规范压力和信息流在考虑影响方面的相对重要性的推论。此外，与将迁移和生育作为结果的文献相反，拟议的研究还将它们视为社会网络地位和社会网络整体结构的潜在决定因素。拟议的研究将使用1984年、1994年和1995年收集的数据，这些数据是南戎中央经济方案调查和中央经济方案-中央经济方案调查的一部分。数据的创新元素包括前瞻性面板设计；研究村庄内100%的家庭和个人样本；对一部分村庄的外来移徙者的后续行动以及将他们与原籍家庭联系起来的能力；完成多层次、多关系的社交网络数据。最后一种方法将用于发展网络位置（中心性、路径长度、组件成员）和结构（密度、平均路径长度、隔离流行率、组件数量）的定量测量，这些将在基于回归的发现外来移徙者可能性的统计模型中发挥重要作用；他们与原籍户之间汇款流动的构成、金额和方向；以及移民、返乡移民和非移民所做的避孕选择。网络位置的措施将是调查家庭规模和变化对村庄中其他家庭关系影响的模型的重点。所提出的统计技术考虑了聚类的选择性和模式

The proposed research explores interrelationships between migration, contraceptive choice, and social networks using a unique set of social surveys collected in Nang Rong, Thailand. Social networks- i.e., sets of relations between individuals, households, and communities -are key to the dissemination of information and diffusion processes more generally. They are also fundamental to an understanding of norms, normative pressure, and conformity. The proposed research will shed light on these mechanisms by investigating: (a) social networks in the place of origin and the likelihood of finding and successfully interviewing out-migrants; (b) the implications of social networks at the origin and connections between the origin and destination for the amount, composition, and directionality of remittance flows; (c) the effect of social network position on contraceptive choice. Comparisons of kin-based networks with networks based on economic assistance and exchange, and of networks at multiple levels of analysis will make it possible to draw some inferences about the relative importance of normative pressure and information flow in accounting for effects. Further, in contrast to literatures preoccupied with migration and fertility as outcomes, the proposed research will also consider them as potential determinants of social network position and the overall structure of social networks. The proposed research will use data collected in 1984, 1994 and 1995 as part of the Nang Rong CEP and CEP-CPC Surveys. Innovative elements of the data include the prospective panel design; 100 percent samples of households and individuals within study villages; the follow-up of out-migrants from a subset of villages and the ability to link them to origin households; and complete social network data at multiple levels and for multiple relations. The last will be used to develop quantitative measures of network position(centrality, path length, component membership) and structure (density, average path length, prevalence of isolates, number of components) which will be featured in regression-based statistical models of the likelihood of finding out-migrants; the composition, amount and directionality of remittance flows between them and the origin households; and contraceptive choices made by migrants, return migrants, and non-migrants. Measures of network position will be the focus of models investigating the effects of household size and change for the ties with other households in villages. Prosposed statistical techniques take account of selectivity and patterns of clustering
