17 pages., Online via UI electronic subscription, Case study assessing the effects of the 2005 Dietary Guidelines published jointly by the U.S. Department of Health and Human Services and U.S. Department of Agriculture. Findings suggested that release of the guidelines and related media attention increased availability and sales of whole-grain foods. Emphasized the key role of product reformulation, induced by competition among food suppliers.
Authors emphasize how factors that influence media coverage of climate science intertwine and diverge in the United States and United Kingdom. Journalism and public concerns have shaped decisions in climate science and policy , just as climate science and policy have shaped media reporting and public understanding.

18 pages., via online journal., This essay explores the different meanings of the 1960s’ pesticide controversy
as conveyed by the multiple representations of Rachel Carson’s Silent Spring
(1962). I argue that to understand the impact of Carson’s work on a heterogeneous audience in the early ’60s, we must move beyond an examination
of the book, Silent Spring, to consider its other media manifestations, as a
serialization for The New Yorker and as a television expose for “CBS Reports.” ´
Each conveyed a unique message stylized for the audience of that particular
media. This analysis demonstrates the problems and opportunities for scholars
attempting to gauge the influence of a book on the public understanding of
science. This argument also suggests that to understand the transition of
environmentalism from a grass-roots movement to near universal consensus,
we need to examine carefully the role of media in shaping divergent messages
for different audiences—a phenomenon that assisted in transforming local
environmental issues into a matter of national concern.
13 pages., via online journal., Many rice farmers decide to spray insecticides based on their perception of potential damage and losses caused by pest species. Farmers generally overestimate the seriousness of the rice leaf folder from visible damage and apply insecticides early, and therefore, changing perceptions may help reduce the perceived benefits of unnecessary spraying. Farmers in Long An province, Vietnam, were motivated to ‘test’ a heuristic or rule of thumb, ‘insecticide spraying for leaf folder control in the first 40 days after sowing is not needed’, by the distribution of carefully designed communication media materials. The media reached 97% of the farmers in the study sites. Leaflets, radio drama and posters had the most effective reach. Thirty-one months after the media introduction, the number of insecticide sprays dropped significantly from 3.35 sprays per farmer per season to 1.56. The proportion of farmers spraying at early and late tillering and booting stages was reduced from 59%, 84% and 85% to 0.2%, 19% and 30%, respectively. Those who did not use any insecticides increased from 1% to 32%. Correspondingly, farmers' perceptions of leaf folder damage as indicated in a belief index, decreased significantly from 11.25 to 7.62. The proportion of farmers who believed that leaf folders could cause losses was reduced from 70% to 25%, as did those who believed that early season spraying was required, from 77% to 23%, respectively. Farmers' insecticide spray frequencies and the belief index were significantly correlated and were not significantly different between farmers who had attended farmer field school training and those who had not. The cost (insecticide and labour) saving was the most important incentive for farmers to stop early season spraying as cited by 89% of the farmers. A survey of 12 other districts in Long An showed that 82% of the province's 210000 households were reached. About 20% had not applied any insecticides, 77% had stopped early season spraying and the average number of insecticide sprays was 1.6 (compared with 1.55 in study sites). The approach was readily adopted by extension in 15 provinces that launched their own programmes, extending to the whole Mekong Delta of 2 million farmer households.
