18 pages, Universities must strategically communicate agricultural science to effectively reach millennials skeptical of agricultural innovations and constantly assessing the credibility of online information. Universities are trusted information sources and must maintain credibility on social media platforms such as Twitter, used by millennials to receive and share information. Source credibility seeks to understand message source and recipient characteristics that influence recipients’ perceptions of a source’s expertise and trustworthiness. The purpose of this study was to explore differences in engagement when specific factors affecting source credibility were emphasized when communicating with millennials about agricultural science on Twitter. The purpose was accomplished by describing the level of engagement and the differences in engagement observed between perceived gender, race, and age of university scientists. Over seven months, researchers wrote press releases about published journal articles authored by two or more diverse, university-affiliated scientists. They published multiple tweets about each release, with the only difference being the scientists’ headshots. Scientists were categorized as perceived male versus female, White versus Non-White, and older versus younger. Descriptive analysis of engagement metrics from 32 tweets found those with females performed better than those with males. Non-White scientist tweets performed better with the exception of engagement rate. Tweets featuring younger scientists received more engagement than older. The exploratory results implied tweets featuring young, Non-White females may elicit higher engagement. Future studies should examine if engagement metrics are correlated with source credibility dimensions. Strategically featuring diverse scientists in research communication may be utilized to build engagement in universities’ social media.
21 pages, Because mothers are the primary grocery shoppers for most households, they play a fundamental role in the food their families eat. As such, it is important to understand their perceptions of potential sources of food safety and nutrition information. This study surveyed young mothers (i.e., 18-40 years old) across the United States to assess their awareness, knowledge, and trust of celebrities and social media influencers who communicate about food-related topics. The list of celebrities and influencers consisted of TV chefs, celebrities and influencers who espouse favorable viewpoints of food and agriculture, and celebrities and influencers who espouse more alternative viewpoints of food and agriculture. Respondents were usually more aware and knowledgeable of the celebrities and chefs than the influencers. They also generally trusted the TV chefs the most. There tended to be small-to-medium positive correlations between a respondents’ knowledge of a celebrity/influencer and their trust of that celebrity/influencer but not all were statistically significant. Communicators looking to influence the largest number of people would benefit more from working with celebrities, but social media influencers could still play a role in campaigns that target specific online communities where the influencers’ values align with community members. More research is recommended to expand to other audiences, as well as assessing other celebrities and influencers. Research can also address how consumers use social media to get food-related information, how trust could be affected by communication using different social media platforms, and content analyses of food-related communication by celebrities and influencers on social media outlets.
