Examining the Impact of Expert Voices: Communicating the Scientific Consensus on Genetically-modified Organisms

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 pre-manipulation 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.     

Diversity of Television Exposure and its Association with the Cultivation of Concern for Environmental Risks

Cultivation theory claims that individuals who watch a greater amount of television are more likely to accept the representation of reality as presented on television. This study introduces the variable of exposure diversity and attempts to investigate if the diversity of television channels viewed plays a significant role beyond the amount of television viewed in the cultivation of concern about environmental risks. Data from the 2002 annual Life Style Study conducted by Synovate for DDB-Chicago was paired with a corresponding content analysis of environmental television coverage. Ordinary-Least-Squares regression suggests that exposure diversity is associated with concern of environmental risks above and beyond both the effects of the amount of television watched and individual differences, suggesting the variable of exposure diversity holds promise for further explicating cultivation theory.     

The Misdiagnosis: Rethinking “Nature-deficit Disorder”

This study examines and critiques “nature-deficit disorder” (NDD), Richard Louv's popular theory of how and why children are alienated from nature. Specifically, I explore NDD within the context of one forest conservation education program that aligns with and operationalizes Louv's message. Underlying Louv's and forest educators' discourses are culturally specific assumptions about human-nature relationships. Both evoke a fall-recovery narrative—that children are separated from nature and must return—and promote science and naming to reconnect. I argue that, in the absence of deeper cultural examination and alternative practices, NDD is a misdiagnosis—a problematic contemporary environmental discourse that can obscure and mistreat the problem. I call on adults to rethink human-nature disconnectedness by returning to the psyche, digging deeper to the problem's cultural roots, and using nontraditional communication practices such as emotional expression and non-naming.     

Communicating in Germany about the Fukushima Accident: How Direct Encounter Beat Media Representations

The Fukushima nuclear accident revived the question of whether current practices of technical communication can fulfill the needs of various audiences during a complex global crisis. In that context, the Institute of Nuclear Technology and Energy Systems in Stuttgart organized a public presentation on the technical aspects of the Fukushima nuclear accident. Its success indicates that direct encounter was preferred to media representations of the accident by Stuttgart's citizens. This event demonstrated that public presentation can provide a successful model for technical communication in situations of global sociotechnical crisis.     

Culture,Progress and the Media: The Shad as Synecdoche in Environmental News Coverage

This essay examined the use of synecdoche in newspaper coverage of a dispute over water rights between the Mattaponi Indians and the city of Newport News, Virginia. The Mattaponi used the shad as a rhetorical trope to explain the tribe's relationship to the river and their fears about the reservoir's impact. The reservoir proponents, however, treated the shad as a representation of the conflict surrounding the reservoir, and this construction was reflected in articles that appeared in The Daily Press, a local daily newspaper. This essay argued that, ultimately, the treatment of a single species as a synecdoche in environmental disputes undermined the Mattaponi's position. The media which are instrumental in defining environmental issues for the public, misinterpreted a rhetorical trope that was proffered as a representation for a complex set of values and instead focused attention on the species itself rather than the values that it represented.     

The environmental impact statement comes to Israel: An initial assessment

Despite obstacles inherent in the structure of government and the lack of a strong national constituency, environmental impact assessment became a policy-making element in the government of Israel in 1982. The Environmental Protection Service formed in 1973 now needs to develop strategies to promote environmental awareness and environmentally informed decision making among the public, private and public developers, and within the Ministry of the Interior.     

Knowledge production and the science–policy relation in Dutch soil policy: results from a survey on perceived roles of organisations

In this paper, we present results from a survey on the perceived roles of organisations on the production and transfer of knowledge in Dutch soil policy. The results are interpreted by applying three theoretical perspectives to this relation: technical communities, epistemic communities and Mode 2 knowledge production. The main research results show that, since the perceived roles of organisations in some cases do not match the intended roles, or are inconsistent, communication of roles by organisations in the policy field is not effective. A second conclusion is that the respondents advocated an increase in interaction among policy levels and between knowledge production and policymaking. From the results, it seems that the Dutch soil policy field is on its way to a mode of socially robust knowledge production, where knowledge production, knowledge transfer and policymaking are integrated. In order to further this development, the paper provides recommendations on the further integration of science and policy concerning soil policy in the Netherlands.With respect to the methodology of survey research on the interaction between science and policy, the paper illustrates the importance of the professional identities of the respondents. The professional identities of the respondents are an important explanatory variable for the perceived roles of organisations.
