11 pages., via online journal., This study compared researchers, extension agents, and farmers’ perceptions of the effect of Information Communication Technology (ICT) on agricultural information access. A simple random sampling technique was used to select 88 researchers, 115 extension agents, and 271 farmers. Data collected through a structured questionnaire were analyzed using means, standard deviation, and one-way analysis of variance. The results showed that, of the 29 statements on the rating scale, researchers, extension agents, and farmers agreed with and were positively disposed to 25, 23, and 19, respectively. A significant difference in the effect of ICT on agricultural information access among researchers, extension agents, and farmers (F = 6.49, p < .05) was observed. Access to agricultural information through ICT will continue to improve, since perceptions are overtly positive among researchers, extension agents, and farmers.
21 pages., via online journal., Scholars are divided over whether communicating to the public the existence
of scientific consensus on an issue influences public acceptance of the
conclusions represented by that consensus. Here, we examine the
influence of four messages on perception and acceptance of the scientific
consensus on the safety of genetically modified organisms (GMOs): two
messages supporting the idea that there is a consensus that GMOs are safe
for human consumption and two questioning that such a consensus exists.
We found that although participants concluded that the pro-consensus
messages made stronger arguments and were likely to be more
representative of the scientific community’s attitudes, those messages did
not abate participants’ concern about GMOs. In fact, people’s premanipulation attitudes toward GMOs were the strongest predictor of of our outcome variables (i.e. perceived argument strength, post-message GMO
concern, perception of what percent of scientists agree). Thus, the results
of this study do not support the hypothesis that consensus messaging
changes the public’s hearts and minds, and provide more support, instead,
for the strong role of motivated reasoning.
16 pages., Via online journal., This study explores potential factors that lead to environmental opinion leadership behaviors such as informing the public about environmental issues and encouraging preventative behaviors among various social groups. Building on the theoretical framework of the diffusion of innovations model, these analyses explore the effects that mass media may have on perceptions of self-efficacy among opinion leaders and how self-efficacy may, in turn, encourage leaders to communicate about aquatic invasive species (AIS) to others in their social networks. Results indicate that mass media and governmental media can have both a positive and negative influence on levels of self-efficacy, and that opinion leaders with higher levels of self-efficacy are more likely to participate in behaviors that could potentially influence their social network(s). These findings not only highlight factors that influence opinion leadership regarding advocacy of environmental behaviors, but also offer insights as to how future campaigns can work with these groups to promote prevention strategies.
9 pages., Via online journal., Intergenerational environmental communication (IGEC) was examined using pre- and post-survey research after child participation in a groundwater environmental education (EE) program. The EE program increased child knowledge, but did not significantly increase parent knowledge. There was also a significant difference between perceived levels of environmental communication (EC) between child and parent, with parents indicating higher levels of EC than their children. Participants reporting low EC levels had significantly less interest in, concern for, or knowledge about environmental issues. Several key factors initiated IGEC between children and their parents, including saving household money by changing environmental behaviors, exposure to media sources that reported environmental news, and school activities such as homework related to environmental issues. Environmental educators should be cautious when implementing EE programs, as additional considerations are essential to determine what influence, if any, child participants have beyond the classroom. Continued research is needed to increase EC between children and their parents with the hope of improving intergenerational approaches to environmental issues.
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.
12 pages., via online journal, We examined how information from multiple communication channels can inform social norms about local food purchasing. The concept of social exposure was used as a guide. Social exposure articulates how information in social, symbolic, and physical environments contributes to normative perceptions. Data was collected from a sample in Wisconsin. Results indicated that information from communication channels representing symbolic, social, and physical environments all contributed to normative perceptions. We also found that for individuals who frequent farmers’ markets, information from some communication channels was relatively less strongly associated with injunctive norms. It may be that when first-hand, experiential information is available to inform norms, individuals rely less on information available through other communication channels. Future work might further explore how farmers’ markets foster information sharing in communities, as such information may contribute to normative perceptions.
