Increasing discussion over the safety of natural resource extraction and transportation to facilitate international energy needs has given rise to controversy over the prospect of large quantities of bitumen and crude oil flowing through trans-national pipelines. This debate, incorporating the voices of industry, government and advocacy groups, has gained traction in the news media, alternately framed as an environmental, economic, trade, human rights or public safety concern. It is possible, however, that such coverage may vary substantially with regional interests and perceptions of costs and benefits, locally or nationally. To uncover how the framing of energy transportation varies with proximity considerations, regional and national media coverage in Canada and the United States of the Keystone XL pipeline from 2010 to 2014 is analyzed. National and local papers frame the pipeline according to different considerations, as do cities near to and distant from the pipeline route.  相似文献

Sea-level rise is a dramatic effect of climate change, with profound implications for societies around the world. In the past few years, a rush of literary non-fiction books have appeared that aim to explain the threat of rising seas to the public. This paper critiques how sea-level rise is framed in many of those books, on two accounts. First, anthropogenic sea-level change is frequently framed by accounts of natural variations of sea level in earth history, focusing on geological rather than societal processes. Second, single and sudden floods are often used to exemplify sea-level rise in ways that draw attention away from incremental environmental change in favour of fast-paced but de-contextualized events. The paper argues that both these frames de-politicize sea-level rise and may steer public understanding and discussion away from relevant social, cultural, and ethical considerations. As examples of climate reductionism, these depictions may obstruct rather than facilitate appropriate negotiations in response to predicted sea-level rise.  相似文献

Hydraulic fracturing, or fracking, is a controversial but popular method of extracting oil and gas in North America. There are a myriad of completing claims about the economic benefits and the environmental costs of the technology. This paper examines news media coverage of fracking in four Canadian and four American newspapers over a five-year period. A comparison is made at the national level as well as at a paired subnational level between jurisdictions where fracking is embraced and where fracking is banned. The paper demonstrates that in both countries the main storyline is about water quality, but beyond that differences emerge as Americans focus more on wildlife and public health and Canadians focus more on moratoriums and energy independence. Moreover, while there were similarities in media coverage of fracking in pro-fracking and anti-fracking jurisdictions, there were notable differences in attention to the topics of public health and economic benefits.  相似文献

Although there is increasing public awareness of global warming, there is a gap between such perception and relevant actions to combat the problem. In order to develop effective strategies for facilitating public actions, in this paper we draw upon framing theory and a dual processing model. Based on an experiment involving 261 participants from a large public university in Taiwan, this study found that by framing global warming as a local issue, communication messages can trigger both analytic (issue relevance) and affective (negative emotions) appraisals, which, in turn, will increase people's intentions to take actions. This study provides important insights for government and environmental groups when designing communication campaigns on this issue.  相似文献

This paper explores a technique for mitigating framing effects in perceptions of global climate change. People's opinions on issues ranging from same sex marriage and the environment to free speech and health care have been shown to be influenced by the way in which the issue is presented: the metaphors, images, and catchphrases that communicate implicit normative messages about the issue. The work described here synthesizes insights from experimental research on moderators of framing effects and sociological research on frame reflection. Based on this synthesis, this paper describes a test of a simple highlighting technique for focusing respondents' attention on the framing operating in political materials. Results suggest that this intervention not only can reduce the opinion-shaping impact of frames but may also reduce ideological polarization. Implications include a better understanding of the mechanisms by which frames operate, techniques for making frame reflection possible among political non-elites, and recommendations for strengthening environmental groups' public communication strategies.  相似文献

Research on frames in climate change (CC) news coverage has advanced substantially over the past decade, but the emerging understanding of the framing role of visual imagery that often accompanies news texts remains fragmented. We report on a set of image frames identified through content analysis of 350 images associated with 200 news articles from 11 US newspaper and magazine sources from 1969 through late 2009. We reliably identified and quantified the occurrence of 118 image themes. We then hierarchically clustered the themes based on their co-occurrence in images to identify an integrated framework of 42 image frames. We highlight frames associated with particular types of images (e.g., photographs and maps) or geographic regions. From among the full set of frames, we identify 15 that commonly appear in US CC news imagery and discuss the ways in which image frames make salient (or render invisible) particular categories of people, geographic regions, aspects of science, and spheres of activity.  相似文献

This paper explores the perceptions of policy makers and rural agricultural producers in respect of policy framing and adaptation to climate change, social learning and stakeholder input (participation) surrounding two successful agri-environmental programmes in Saskatchewan, Canada. Given the record of success of these two programmes in reducing vulnerability to climate change, this study provides an opportunity to explore certain attributes of adaptive management, including: what attributes make policy and programmes responsive; how government can frame programmes facilitating adaptation to climate change; what types of mechanisms can or should be used to engage with producers; and perhaps most importantly, what producers expect of government, government policies and programmes in relation to adaptation to climate change.  相似文献

The development of horizontal hydraulic fracture drilling or “fracking” has allowed for the extraction of deep, unconventional shale gas deposits in various shale seams throughout the USA. One such shale seam, the Marcellus shale, extends through New York State, Pennsylvania, and West Virginia, where shale gas development has rapidly increased within the last decade. This has created a boom of economic activity surrounding the energy industry. However, this bounty comes with risks to environmental and public health and has led to divisive community polarization over the issue in the Marcellus shale region. In the face of potential environmental and social disruption, and a great deal of controversy surrounding “fracking” the oil and gas industry has had to undertake a myriad of public relations initiatives to legitimize their extraction efforts in the Marcellus shale region, and to frame the shale gas boom in a positive light to stakeholders. This article investigates one such public relations initiative, the Energy in Depth (EID) Northeast Marcellus Initiative. Through qualitative content analysis of EID's online web material, this article examines the ways in which the industry presents and frames natural gas development to the general public. Through appeals to patriotism, the use of environmental imagery, and a claimed commitment to scientific reason, the oil and gas industry uses EID to frame the shale gas extraction process in a positive light, all the while framing those who question or oppose the processes of shale gas extraction as irrational obstructionists.  相似文献
