Take a look at a recent Maxine Goodman Levin School of Urban Affairs publication:
Cross-Sector Emergency Information Networks on Social Media: Online Bridging and Bonding Communication Patterns by Clayton Wukich, Qian Hu, and Michael D. Siciliano
Document Type: Article
Publication Date: July 2019
A key challenge for public administrators is facilitating communication among diverse actors. This article illustrates the information seeking and sharing preferences of notable emergency information suppliers on social media who operate primarily within four states. Through homophily and brokerage analyses, two basic communication preferences were noted: (a) bridging patterns in which actors interact with diverse sources of information, and (b) bonding patterns in which actors rely on sources from similar backgrounds. Both provide value for practitioners. A crucial task, then, is to balance those approaches and adjust to the shifting demands of the external environment.
