《Environmental Communication: A Journal of Nature and Culture》2013,7(2):255-276
Scholars of environmental communication acknowledge the importance of visual representations in shaping perceptions and actions in relation to environmental affairs. Unlike with other media, including newspapers, television and film, research on the visualization of nature and environmental issues in magazines is rare. This study focuses on the covers of Time magazine, one of the world's most influential news weeklies. A dataset that includes all relevant covers from 1923 to 2011 is examined using a combination of quantitative and qualitative content analysis to analyze the visual representation of nature and environmental issues. The results show that the presence of environmental issues and nature on the covers has increased over the decades. Furthermore, Time takes an advocacy position on some environmental issues, but it is a shallow one that is weakly argued through less-than-engaging imagery and fails to offer much in the way of solutions or agency to the reader. 相似文献

Environmental communication scholarship is critical to the success of sustainability science. This essay outlines three pressing areas of intersection between the two fields. First, environmental communication scholarship on public participation processes is essential for sustainability science's efforts to link knowledge with action. Second, sustainability science requires collaborations across diverse institutional and disciplinary boundaries. Environmental communication can play a vital role in reorganizing the production and application of disciplinary knowledge. Third, science communication bridges environmental communication and sustainability science and can move communication processes away from one-way transmission models toward engaged approaches. The essay draws on Maine's Sustainability Solutions Initiative to illustrate key outcomes of a large project that has integrated environmental communication into sustainability science. 相似文献

PROBLEM: Supervisors are increasingly important to the functioning of manufacturing operations, in large part due to their role as leaders. While supervisors' relations and communication with their subordinates are known to be important in influencing subordinates' behavior, little is known about how these two factors will impact subordinates' safety. This study investigated how much each factor contributes to safety-related outcomes for blue-collar production employees. METHOD: Production employees at five Pennsylvania wood manufacturers completed a survey during their work shift. Five hundred and ninety eight employees provided data on leader-member exchange (LMX), safety communication, and safety-related events. Archival data on OSHA recordables were also obtained from the producers' human resources database. RESULTS: Analyses found that the influence of LMX was greater than that of safety communication in predicting safety-related events. Neither LMX nor safety communication was significantly related to OSHA recordables. Results also demonstrated that employee job satisfaction and demographic variables such as gender and age have safety implications. IMPACT ON INDUSTRY: Results from this study further emphasize the importance of production supervisors and illustrate the potential role of leader-member exchange in enhancing workplace safety. Specifically, organizations should foster positive social exchange between their employees and supervisors and enhance the leadership qualities of supervisors to help reduce workplace injuries. 相似文献

Given progress in policies for pursuing sustainable development, promoting commitment to thinking and acting more far-sightedly has become the primary strategic challenge. In the face of impatience, selfishness, uncertainty, analytical limitations, and vulnerability, strategies for promoting far-sightedness can be identified by assessing how these obstacles can be overcome. Strategies for creating or rescheduling tangible and deference rewards, realigning performance evaluations, implementing cognitive exercises, framing communications, altering decision-making processes, using self-restraint devices both to resist temptation and to enhance credibility, altering institutions to empower the patient, and stabilizing living conditions are the major categories for identifying and assessing the many strategies which arise out of both ordinary and constitutive policy initiatives.

Water information: what is it good for? The use of information in transboundary water management 总被引:3,自引:1,他引:2
Consistent and relevant information on the status of water systems is indispensable for rational and cost-effective water management. This statement has general validity for all types of river basins, but is particularly relevant for transboundary water regions. Information is used to support decision-making and to evaluate the effects of water resources management decisions. Information production however lags behind developments in water management, which becomes clear from the fact that information still focuses on ecological components of water bodies and largely ignores the importance of socio-economic data stemming from human activities taking place in the river basin. Production of improved information is hindered by strong boundaries between different disciplines that are not easily overcome. Moreover, consideration of information needs and the goals of information dissemination prior to producing information is insufficient and the relevant actors are often reluctant to participate in these processes as they are time consuming. Differences in institutional behaviour also hinder cooperation between institutions, while organisational structures are insufficiently tuned to the needs of the external environment. All these issues hinder the use of information as the basis for decision-making. This paper provides an overview of relevant aspects of information from a broad range of perspectives and establishes the need for changes in the production and use of environmental information in support of water management. The paper is largely based on the outcomes of a closed multi-disciplinary specialist meeting on the role and use of environmental data and information in transboundary water contexts held in Arendal, Norway, September 2002. 相似文献

Environmental Reporting by the Fortune 50 Firms 总被引:1,自引:0,他引:1
/ The extent and use of industry-reported environmental data are increasing, warranting an in-depth analysis of this information. This paper reviews the environmental reporting guidelines issued by several business and nonprofit organizations and evaluates the environmental reports published by the Fortune 50 companies, half of which publish reports. After describing the history of environmental reporting and the content of the guidelines, a comparative evaluation is made to indicate the types of companies producing reports, the topics reported, the intended audiences, the scope and depth of the material reported, and the effectiveness of the reports as communication devices. These reports are mechanisms to enhance a firm's image, public relations, and marketing and are aimed largely at concerned individuals, affected communities, and investors. Significant differences in the content and the depth of reports are seen as firms report on topics that are perceived by the public as high risks. The most complete reports are published by industries with poor or controversial public images, e.g., the chemical and timber industries. Still, no report provided information that was sufficient for comprehensive or comparative analyses of environmental performance. Recommendations are provided to increase the quality and effectiveness of environmental reporting.KEY WORDS: Communication; Environmental management; Performance reporting; Reporting; Stakeholder 相似文献

The regulation of protein collection through pollen foraging plays an important role in pollination and in the life of bee
colonies that adjust their foraging to natural variation in pollen protein quality and temporal availability. Bumble bees
occupy a wide range of habitats from the Nearctic to the Tropics in which they play an important role as pollinators. However,
little is known about how a bumble bee colony regulates pollen collection. We manipulated protein quality and colony pollen
stores in lab-reared colonies of the native North American bumble bee, Bombus impatiens. We debut evidence that bumble bee colony foraging levels and pollen storage behavior are tuned to the protein quality (range
tested: 17–30% protein by dry mass) of pollen collected by foragers and to the amount of stored pollen inside the colony.
Pollen foraging levels (number of bees exiting the nest) significantly increased by 55%, and the frequency with which foragers
stored pollen in pots significantly increased by 233% for pollen with higher compared to lower protein quality. The number
of foragers exiting the nest significantly decreased (by 28%) when we added one pollen load equivalent each 5 min to already
high intranidal pollen stores. In addition, pollen odor pumped into the nest is sufficient to increase the number of exiting
foragers by 27%. Foragers directly inspected pollen pots at a constant rate over 24 h, presumably to assess pollen levels.
Thus, pollen stores can act as an information center regulating colony-level foraging according to pollen protein quality
and colony need.
