29 pages, via online journal, Using an online between-subject experiment, this study tested the effects of message framing (gain vs. loss), reference point (self vs. other), and modality (text vs. infographics) in the scenario of recycling promotion. The findings identified that modality determines under what circumstances message strategies make a difference in risk perception and optimistic bias. In particular, only when paired with infographics and other-referencing point are loss-framed messages more effective than gain-framed messages in increasing risk perception and reducing the self-other gap in perceived benefits. Moreover, risk perception variables and the self-other risk perceptual gap were significant predictors of promoted behavioral intentions.
30 pages, via online journal, Environmental journalists, as gatekeepers, often become arbiters of risk and benefit information. This study explores how their routine news value judgments may influence reporting on marine aquaculture, a growing domestic industry with complex social and ecological impacts. We interviewed New England newspaper journalists using Q methodology, a qualitative dominant mixed-method approach to study shared subjectivity in small samples. Results revealed four distinct reporting perspectives—“state structuralist,” “neighborhood preservationist,” “industrial futurist,” and “local proceduralist”—stemming from the news value and objectivity routines journalists used in news selection. Findings suggest implications for public understanding of, and positionality toward, natural resource use and development.

14 pages, via online journal, Research on the gateway belief model indicates that communicating the scientific consensus on global warming acts as a “gateway” to other beliefs and support for action. We test whether a video conveying the scientific consensus on global warming is more effective than a text transcript with the same information. Results show that the video was significantly more effective than the transcript in increasing people’s perception of scientific agreement. Structural equation models indicate indirect increases in the beliefs that global warming is happening and is human-caused, and in worry about global warming, which in turn predict increased global warming issue priority.
28 pages, via online journal, While uncertainty is central to science, many fear negative effects of communicating scientific uncertainties to the public, though research results about such effects are inconsistent. Therefore, we test the effects of four distinct uncertainty frame types (deficient, technical, scientific, consensus) on three outcomes (belief, credibility, behavioral intentions) across three science issues (climate change, GMO food labeling, machinery hazards) with an experiment using a national sample (N = 2,247) approximating U.S. census levels of age, education, and gender. We find portraying scientific findings using uncertainty frames usually does not have significant effects, with an occasional exception being small negative effects of consensus uncertainty.
27 pages, via online journal, This study explored whether satire (an emotional blend of humor/indignation) can minimize the emotional tradeoffs researchers have documented for humorous appeals about climate change. Using a sample of U.S. young adults, we conducted a 2 (humor: present/absent) × 2 (indignation: present/absent) + 1 (control) experiment in which we manipulated a climate change segment from Jimmy Kimmel Live! Our evidence suggests that it is possible for a late-night host to affect young adults’ climate change risk perception and behavioral intentions under certain conditions. Moderation analyses indicated that avoiding humor helped close the partisan gap in risk perception between Republicans and Democrats.
23 pages., via online journal., In 2015, the Philippine Supreme Court ruled against the field testing of Bt eggplant, a genetically modified crop. This decision was covered extensively in the local press, forcing scientists to defend their research. We used qualitative, inductive analysis to examine how three news outlets constructed science in their coverage of the issue. We found that science was constructed through four themes: science searched for proof, absolute consensus had to be reached, the characteristics of scientific inquiry are used to discredit scientists, and science is aware of its logical limits. These findings have implications for the public acceptance of innovations.
24 pages., via online journal., The present study investigated the effects of communication styles, source expertise, and audiences’ preexisting attitudes in the contexts of the debate regarding genetically modified organisms. A between-subject experiment (N = 416) was conducted manipulating communication styles (aggressive vs. polite) and the expertise of the communicator (scientist vs. nonscientist) in blog articles. The results showed significant effects of communicator expertise and individuals’ preexisting attitudes on writer likability and message quality, depending on the communication style used. Expectancy violation was found as a significant mediator that explains the differences. These findings provided a plausible explanation for the way in which communication styles work in science communication contexts and offered practical implications for science communicators to communicate more strategically.

34 pages., via online journal, he use of antibiotics in agriculture contributes to antimicrobial resistance. We surveyed German farmers (n = 336) on their intention to adopt alternative antimicrobial agents (AAA) and used the diffusion of innovations approach as a theoretical guide. (1) Farmers’ views regarding the relative advantage and complexity of AAA, (2) their use of and trust in information sources and channels, and (3) various individual and organizational characteristics were entered as predictors in two explorative models. While farmers’ intention to adopt AAA was generally very high, selected variables in all three categories predicted variations in the intensity of the adoption intention.
17 pages, via online journal, Sarcastic content is prevalent in online social media, although little research has explored its effects. In this study, we examine how exposure to one-sided versus two-sided sarcastic perspectives on climate change shapes beliefs about climate change. We find that exposure to one-sided messages that use irony to deride those who believe that climate change is a hoax (presented in The Onion) raises belief certainty in and perceived risk of climate change for those who do not already believe climate change is an important issue (N = 141). The two-sided message (presented by The Weather Channel) does not show any effects.
