Bounded Solidarity Confirmed? How Korean Immigrants' Mobile Communication Configures Their Social Networks
对美国韩国移民的移动通信使用与社交网络特征进行分层回归分析，发现与同族强关系的短信交流与族群网络中心性显著相关，而与异族弱关系的语音通话则与网络多样性相关，为有限团结理论提供了新证据。
A hierarchical regression analysis of U.S.-based Korean immigrants' mobile communication use (i.e., voice calling and texting) and their social network characteristics (i.e., network size, diversity, and centrality) revealed significant associations between texting with coethnic strong ties and network centrality within the ethnic community. Korean immigrants who texted frequently with both coethnic and host weak ties had larger networks. Network diversity was, however, associated only with voice calling with host ties (both strong and weak). These findings have implications for theories of bounded solidarity. Specifically, the results suggest that mobile communication is significantly associated with (a) denser social networks, and (b) an important and unique source of social capital embedded in immigrant communities.
