Two studies were performed to research potential exemplification effects throughout various stages of natural disasters. Exemplification theory (Zillmann, 1999, 2002) promotes the use of exemplars, media examples, because of their potential ability to motivate risk related information seeking and their possible influence in optimizing protective action (Zillmann, 2006). Study one examined potential exemplification effect differences between various stages of natural disasters. Study two was designed to test for differences in trust, perceptions of severity, and intentions to volunteer depending on the organization type supplying related exemplars in social media. Results indicate that exemplification effects do not differ depending on disaster stage. However, exemplification effects do depend on the source of the exemplars. Furthermore, differences in perceptions of trust were detected between the two organizations providing the exemplars. And, intentions to volunteer vary depending on the current disaster stage. Specific findings, related theoretical implications, and practical suggestions are discussed.

Public housing structures that are deemed “severely distressed” are being demolished and replaced with mixed-income developments. The current study examines the role that social service organizations play in the relocation of public housing residents. Service organizations tend to locate in areas anchored by public housing complexes where the need for their services is immense. Organizations that lose clients due to relocations run the risk of losing the funding they get for serving that population. GIS mapping and semi-structured interviews were used to answer questions about how redevelopment affects the communication infrastructures of public housing residents. GIS mapping was used to determine how services are spatially distributed in relation to public housing developments in Atlanta. Representatives from a sample of those organizations located near current and former public housing locations were interviewed to examine if a strategic communication plan is in place to retain connections with clients during the relocation process.

In an effort to better understand retention, a survey was developed to ask students at a southern land-grant university how they communicate with each other. Communication Infrastructure Theory (CIT) was previously used to identify communication networks in urban neighborhoods. My thesis adapted this theory and networks to identify the strength of three communication techniques of college students and how it effects a student’s sense of belonging which can impact that student’s intent to stay in school.
