22 pages., via online journal., Water is essential for human life, yet safe drinking water is a limited resource. Critical to fighting the global water crisis are public awareness campaigns, including Public Service Announcements (PSAs). While YouTube has become a popular medium for disseminating prosocial content such as PSAs, environmental communication efforts on this platform remain largely uninvestigated. This study examines the content and characteristics of global water crisis PSAs on YouTube by applying two communication models: the Extended Parallel Process Model, and the Elaboration Likelihood Model. These models are used to evaluate the potential effectiveness of the PSAs. Content analysis reveals that threat messages often outweigh efficacy messages in the videos, central route processing cues are more prevalent than peripheral route cues, and a focus on quality or quantity issues differed by sponsoring organization (non-profit, for-profit, government). Implications and avenues for potential future research are discussed.
17 pages, Traditionally, dietary choices are formed through socialization, social norms and the social environment, while news media seemed to have little impact on people’s diets. This article explores whether today’s news media consumption and in particular consuming and sharing information about food on social media are associated with following a vegetarian or vegan diet. The data come from a tailor-made survey carried out in Hamburg, Germany, in 2018 (N = 1,214). Making use of probit regression with multiple equations, we analyse the associations between vegetarianism and individual news consumption, having vegetarians in the social environment, and communicating about food, controlling for individual and family characteristics. We find that both regular news consumption via social media and having vegetarian friends or family members is associated with pursuing a vegetarian diet. Moreover, news consumption via social media comes with increased communication about food, suggesting high relevance of social media for pursuing a vegetarian diet.
