A Multidimensional Approach To Interorganizational Communication Via Emergency Management Organizations And Their Twitter Accounts, Lauren Johnson
A Multidimensional Approach To Interorganizational Communication Via Emergency Management Organizations And Their Twitter Accounts, Lauren Johnson
Theses and Dissertations--Communication
Using an adaptation of O’Connor and Shumate’s (2018) theoretical propositions, this research examines interorganizational communication through the lens of multidimensional networks. Twitter data was crawled from a selection of emergency management organization accounts to measure affinity, representational, flow, and semantic networks. These data included the organizations’ followed accounts, retweets, replies, and mentions. A thematic analysis of the organizations’ mission statements was also conducted in order to inform the examination of the semantic networks. The results show a significant relationship between the number of accounts an organization follows and the likelihood of having its message shared. This research provides a further …
Social Media And Credibility Indicator: The Effects Of Bandwagon And Identity Cues Within Online Health And Risk Contexts, Xialing Lin
Theses and Dissertations--Communication
Three studies were conducted to investigate how social media affordances influence individuals’ source credibility perceptions in risk situations. The MAIN model (Sundar, 2008), warranting theory (Walther & Parks, 2002), and signaling theory (Donath, 1999) served as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. Study One examines whether bandwagon heuristics triggered by retweets would influence individuals’ source credibility judgments. Study Two investigates how bandwagon heuristics interact with different identity heuristics in credibility heuristics on an individual level. Study Three explores bandwagon …

Testing The Message: Making Sense Of Converging Multimodal Messages In A Foodborne Illness Outbreak, Bethney A. Wilson
Theses and Dissertations--Communication
The goal of risk and crisis communication is to reduce and contain the harm inherent in a threat. In order to achieve this goal, risk and crisis scholars call for continued testing of messages surrounding these events; specifically, messages that address the needs of the at-risk message receiver. Previous scholarship suggests that these messages should include adapting and instructing information (Coombs, 2012), and should be designed using pedagogically sound instructional approaches (Frisby, Sellnow, Sellnow, Lane, & Veil, 2011; Sellnow & Sellnow, 2010). In order to meet this call, this dissertation tested an instructionally sound message that includes both adapting and …
