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.
8 pages., Via online journal., With growing interest in food system solutions to address poor health outcomes related to preventable chronic diseases, organizations and researchers are examining the value of community gardens as interventions to promote individual and community health. Research suggests that participation in community gardens improves access to fresh, healthy foods and increases fruit and vegetable consumption. In addition to these physical benefits, research also documents a variety of social and communal benefits, by expanding social capital, stabilizing neighborhoods, and cultivating relationships. Unfortunately, most of these studies focus on a specific case, cross case, or intervention studies within a geographically specific locale. Learning lessons from successful community garden programs can be difficult because community gardens often rely on the synergy of a complex network of support agencies that assist in various technical and educational capacities. The purpose of the study was to demonstrate the use of a framework for program development and evaluation that stakeholders, including extension, can adopt to show program outcomes. The framework used a Delphi approach with a diverse panel of community garden stakeholders to reach consensus about program outcomes. The study demonstrated that the panel could reach consensus on a variety of short-, medium-, and long-term outcomes.
