20 pages., via online journal., This article analyses whether different institutional sources of scientific information have an impact on its credibility. Through a population-based survey experiment of a national representative sample of the Spanish public, we measure the credibility that citizens attribute to scientific information on the evolution of CO2 emissions disclosed by different institutional sources (business associations, government, non-government environmental organisations, international bodies and national research institutions). The findings show that an institutional credibility gap exists in science communication. We also investigate the factors accounting for the credibility of the different institutional sources by examining variables related to knowledge, interest, trust, reputation, deference, attitudes, values and personal characteristics. Exploratory regression analyses reveal that identical variables can produce different effects on the credibility of scientific information, depending on the institutional source to which it is attributed.
8 pages., via online journal., Recent research and practice in environmental management suggest sentiment analysis of social media communication can be a useful tool in stakeholder analysis of environmental policy. This is certainly the case when it comes to the controversial use of biological controls in dealing with invasive species. Current numerical scored approaches of sentiment may not reveal the reasons for support or opposition to environmental policies in this and other areas. In this study, we examine how the use of more in-depth analysis based on what key stakeholders say about this issue in media at a national, city or regional geographic level. The analysis reveals quite different reasons for support and opposition to the biological control of carp in Australia, and that within each stakeholder group it is possible for individuals to hold conflicting views and attitudes on this issue. We find that there are concerns at the national and city level about the impact of the virus and mistrust of government and science and that the carp species may be viewed as a valuable resource. Those responding to regional media expressed hope that the virus may lead to the elimination of the carp problem, however, they were more interested in the possible impact on the local environment. The multi-scaled social media analysis of stakeholder views about the potential biological control of carp in Australia demonstrated how social media comments can be used to explore the nuanced and multidimensional nature of community attitudes and preferences.
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.
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.
16 pages., via online journal., Synthetic biology will probably have a high impact on a variety of fields, such as healthcare, environment, biofuels, agriculture, and so on. A driving theme in European research policy is the importance of maintaining public legitimacy and support. Media can influence public attitudes and are therefore an important object of study. Through qualitative content analysis, this study investigates the press coverage of synthetic biology in the major Nordic countries between 2009 and 2014. The press coverage was found to be event-driven and there were striking similarities between countries when it comes to framing, language use, and treated themes. Reporters showed a marked dependence on their sources, mainly scientists and stakeholders, who thus drives the media agenda. The media portrayal was very positive, with an optimistic look at future benefits and very little discussion of possible risks.
10 pages., via online journal., The main purpose of this study was to categories and describes the profile characteristics of the women beneficiaries, to determine the use of communication sources by the women beneficiaries, and to explore the relationship between the profile characteristics of the women beneficiaries of RDRS with their use of communication sources. Data were collected using interview schedule from a sample of 112 women beneficiaries selected from the population of 280 by multistage random sampling procedure from five villages of Rajendrapur union under sadar upazila of Rangpur district. Use of communication sources by the RDRS women beneficiaries was determined on three dimensions viz. attitude, contact and application, and finally the use of communication sources index (UCSI) was computed. The UCSI ranged from 45.24 to 277.68 with a possible range of 0 to 300. Based on UCSI, among the 10 communication sources the first five communication sources were husband (277.68), neighbours (219.05), RDRS-worker (205.95), RDRS group meeting (193.45) and relatives (160.42). However, the last five communication sources were RDRS officer (134.82), mobile phone (112.80), television (68.75), inputs dealer (63.99) and SAAOs (45.24). The findings revealed that the highest proportion (38.39%) of the women beneficiaries had medium use of communication sources compared to 33.93% low use and 27.68% high use. Among the ten selected characteristics of the women beneficiaries’ education, farm size, annual income, daily time use, credit received and participation in IGAs showed positive significant relationship while fatalism showed negative significant relationship with their use of communication sources. Age, family size and dependency had no significant relationships. The women beneficiaries of RDRS had moderate exposure with various communication sources so, the concerned Government Organizations and Non-government Organizations engaged in extension activities should make necessary arrangements for improving the use of communication sources by them in income generating activities.
16 pages, via online journal article, This study examined the online content of interdisciplinary agricultural center webpages. Content modification dates, mission statements, and content were determined through a content analysis. Many of the websites did not mention a modification date for the content, while many websites had outdated content mostly older than six months. More than two-thirds of the websites provided PDFs that visitor could download to learn more about topics, by many of the websites lacked any media element that was being coded. Additionally, many websites did not use multiple forms of media. More than half of the websites were coded as lacking any social media content or plugins, but out of the websites that did include social media content, Facebook was the most prevalent. The commonalities between the center’s mission displayed on the website and the content theme were analyzed and chi-square tests provided the degree of association. A significant association existed and an alignment between communication strategies and missions of the centers was concluded, which is important when organizations communicate about agricultural science as indicated by previous literature. It is recommended that centers communicate via their websites in a timely manner and allow modification times to be seen to viewers to show their information is up-to-date. Website media content should also be diversified and communicators of these centers should explore the unique communication opportunities provided by social media. Future research should explore the target audience of interdisciplinary agricultural centers and should analyze the messages centers are using to communicate with those audiences.
