In this study, the concept of social integration will be rebuilt along arguments from social exchange theory and applied to close ties in social networks. Visiting children at home is part of daily routine–behaviour based on trust and expectations of reciprocity. Two different approaches to longitudinal modelling of ties in network data show that, once initiated, visits-at-home ties strongly tend towards reciprocity. While the intensification of these ties can be explained by E. Lawler’s affect theory of social exchange, their initiation will be regarded as a rational decision based on uncertainty and costs. Both increase when ethnic boundaries need to be crossed. Ethnic-residential segregation and spatial distance reduce the opportunity structure of inter-ethnic visits, and third-party intervention often inhibits ties in these networks.

社会交流和融入家庭访问网络：第三方干预和居住隔离对跨界的影响

在这项研究中，社会整合的概念将根据社会交换理论的论点重建，并应用于社会网络中的密切联系。在家探望孩子是日常生活的一部分——基于信任和互惠期望的行为。对网络数据中的关系进行纵向建模的两种不同方法表明，一旦启动，在家访问关系就强烈倾向于互惠。虽然这些联系的强化可以用 E. Lawler 的社会交换影响理论来解释，但它们的启动将被视为基于不确定性和成本的理性决定。当需要跨越种族界限时，两者都会增加。民族居住隔离和空间距离减少了民族间访问的机会结构，第三方干预往往抑制这些网络中的联系。
