20 pages., via online journal., For over 70 years the use of opinion leaders in a two-step communication process has been employed and validated. However, despite the accepted importance of communicating with opinion leaders as a means to cascade information to opinion leaders’ networks of influence there have been few empirical studies specifically examining agricultural and natural resource opinion leader communication channel preferences, particularly from an audience segmentation perspective. The results reported in the study capitalize on previous research data examined from a unique perspective. Specifically, communication channel preferences were analyzed according to opinion leader self-reported demographic categories serving as audience segments. Associations between sex, age, level of employment, level of education and geographical region and communication channel preference were analyzed. The results of the study are descriptive and foundational in nature. Overall, the results indicate a dedicated web page or blog is the most preferred communication channel across all audience segments and conference calls are the least preferred communication channel across the majority of audience segments. The Facebook group communication channel had the most variability between audience segments and the LinkedIn group communicational channel had the largest observed effect sizes among audience segments.
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.
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.
