- Notes:
- 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., Policy makers and researchers foresee four investment strategies for conventional pig farmers in contested pork production regions: (1) continue with a cost-price reduction strategy through modernisation and scale enlargement; (2) convert to an intermediate market segment with higher requirements as to animal welfare and environment than conventional; (3) convert to a niche market segment with higher requirements as to animal welfare and environment than intermediate; or (4) quit farming. For policy makers, it is interesting to gain insight in intensive livestock farmer's perceptions regarding these investments and in processes of social interaction that influence farmer decision-making and the potential diffusion of investment strategies over time (Edwards-Jones, 2006). The aim of this explorative study is to analyse the effect of social interaction on diffusion of investment strategies in capital-intensive livestock production systems with groups of Dutch pig farmers, using a simulation game. The game is designed in such a way that contextual factors do not provide a limiting factor. Furthermore, the game is constructed to stimulate interaction and to trigger imagination of participants. Our main research questions for the analysis of the results of the game sessions were: (1) ‘what are differences in diffusion of investment strategies between sessions?’, and (2) ‘to what extent does social interaction affect diffusion of investment strategies?’ A total of seven sessions were played, with 4–8 pig farmers and/or participants who were affiliated to the sector as advisor or successor. All game sessions were video- and voice- recorded, and interaction between participants was transcribed per game session. First, differences in diffusion of investment strategies between sessions were explored. Second, the causes for differences in diffusion between sessions were explored, by looking at the type of investment strategy, communication between participants, and processes of influence. Special attention was given to the influence of opinion leadership. The results of this research show that (1) only investment strategies with a financial benefit did, under influence of social interaction, result in high adoption; (2) for high adoption to occur, communication between participants was necessary; (3) opinion leaders played an essential role in high adoption of investment strategies; and (4) there was a common understanding among participants that favoured scale enlargement. The gaming methodology triggered participants to communicate their tacit knowledge, i.e. assessment criteria that are important in real-life investment decisions, and to experiment with investment strategies.

- Notes:
- 9 pages., Via online journal., Lack of trust is thought to be one of the most significant barriers to the consumption of organic foods, which is an important dimension of sustainable behaviour. Building trust in organic foods is the central objective of this paper. Based on information processing models focusing on what message to transmit and how, and on the premise that to improve trust, two different dimensions (functionality and authenticity) must be managed simultaneously, this paper analyzes the comparative effectiveness of different combinations of message arguments, forms of appeal and sources on consumer trust. To this end, an experiment was designed with a total of 800 participants, in which 36 different treatments were tested. The results show strong interactions between the three variables considered and suggest that the most effective combinations for building trust are: the health argument put across by an expert, the authenticity argument transmitted by a producers’ union, the elitist argument made by an expert and lastly, the social argument transmitted by a public authority, using an emotional form of appeal in all four cases. These results serve to complete the previous literature on the subject, in which communication activities are recommended but the questions of what to say, how to say it and who should say it are not specifically addressed.

- Notes:
- 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.
