The Formation of Transnational Knowledge Networks on Social Media
研究了Twitter上应急管理领域的两个跨国知识网络，发现共享语言和地理邻近性影响网络形成，但组织也会跨越边界寻求高知名度、资源丰富组织的信息，显示社交媒体创建全球知识网络的潜力。
Transnational knowledge networks provide organizations with information useful in addressing shared problems. Social media may enable the formation of those networks, yet their role in the process has received little attention. This article examines the structure and antecedents of two networks facilitated by the microblogging platform Twitter operating in the policy domain of emergency management. One network includes national-level government agencies responsible for disaster response and recovery operations; the other includes nongovernmental organizations in the form of Red Cross and Red Crescent national societies. We use a logistic regression quadratic assignment procedure to test hypotheses derived from related literature. While findings indicate that shared language and geographic proximity shaped network formation, both networks exhibit boundary spanning behavior in which organizations sought out information from high-profile, resource-rich organizations. Those organizations helped to connect otherwise regionally bound clusters and demonstrate the nascent potential of social media to create global transnational knowledge networks.
