Marine ecosystems are under high demand for human use, giving concerns about how pressures from human activities may affect their structure, function, and status. In Europe, recent developments in mapping of marine habitats and human activities now enable a coherent spatial evaluation of potential combined effects of human activities. Results indicate that combined effects from multiple human pressures are spread to 96% of the European marine area, and more specifically that combined effects from physical disturbance are spread to 86% of the coastal area and 46% of the shelf area. We compare our approach with corresponding assessments at other spatial scales and validate our results with European-scale status assessments for coastal waters. Uncertainties and development points are identified. Still, the results suggest that Europe’s seas are widely disturbed, indicating potential discrepancy between ambitions for Blue Growth and the objective of achieving good environmental status within the Marine Strategy Framework Directive.Supplementary informationThe online version of this article (10.1007/s13280-020-01482-x) contains supplementary material, which is available to authorized users. 相似文献

为了探索情感性组织安全文化对员工安全风险的作用机理,从发展型心理契约视角出发,设计情感性组织安全文化、发展型心理契约及员工安全风险测度量表,采用结构方程方法分别构建了情感性组织安全文化对员工安全风险直接作用、间接作用和两种作用耦合情形下的作用模型。结果表明:"情感性组织安全文化"对"员工安全风险"有正向影响,"情感性组织安全文化"对"发展型心理契约"有显著正向影响,同时"发展型心理契约"对"员工安全风险"有显著正向影响;在以上直接作用和间接作用耦合情形下,"情感性组织安全文化"对"员工安全风险"不存在直接的正向作用,但"情感性组织安全文化"通过"发展型心理契约"对"员工安全风险"产生正向影响的效果更加显著。研究表明,通过情感性组织安全文化建设降低员工安全风险,融入促进员工发展型心理契约均衡因素,能起到事半功倍的效果。 相似文献

"社区研究"已有约150年的历史,社区的防灾减灾对策是一个综合性的科学问题。充分发挥社区的防灾减灾功能十分必要,确立社区防灾减灾最优对策在中国的现代化建设和可持续发展战略中具有重要意义。利用复杂性科学的理论和模型来处理社区的防灾减灾对策问题,是系统科学或复杂性科学中的一个有意义的发展方向。本文提出并分析了社区防灾减灾对策研究中的4个问题,即如何界定社区防灾减灾应急管理的角色和方向;何为防灾减灾安全社区;如何预警突发性灾难事件;社区防灾减灾系统是如何自组织的。本文引入复杂性科学理论对社区的防灾减灾对策进行了研究,讨论了复杂性科学应用于社区防灾减灾对策的理论框架。 相似文献

ABSTRACTIn science communication, a prerequisite for reaching different parts of a society is to find out how these publics experience and interpret science. Since rural South African publics are perceived to exhibit a large cultural distance to science, the present exploratory study aimed to know in more detail how rural South Africans perceive and understand science in their local and social contexts. Theoretical notions on cultural distance and the methodological approach of segmentation studies were considered. Semi-structured interviews with rural South Africans were carried out in four towns (n?=?52) that differ with respect to having a large scientific installation in their vicinity, or not. Sensitively comparing local and social contexts helped identifying three different publics who differed regarding their perceptions of science; however, the large scientific installations only made a difference in perceptions for those publics who were generally less exposed to and less knowledgeable about science. 相似文献

Science, politics and environmental policy have for several years been encountering social and institutional as well as scientific challenges, national and international. The normative basis of all sciences is pressurised from three sides: by awareness of the public, who claims more transparency and sensibility from the scientific institutions regarding factual or possible impacts of science-based industrial progress; by the industries, which try to speed up and intensify the industrialisation of knowledge; and by the public policies, which want to see the sciences engaged in ways to mitigate unintended consequences of economic, ecological and social developments. At the same time, environmental policy is undergoing a tremendous sea change both in conceptual and practical matters. Since the Brundtland Report in 1987 and accelerated after UNCED 1992, environmental policy has been struggling to become a groundbreaking new paradigm for the capacity of resolving social and political issues as well. Any successful attempt to alter traditional institutional and mental structures in policy-making toward sustainability presupposes a renewed association of co-operation, deliberation and decision making. Results from theory of democracy, studies in science and technology, and evaluation studies in environmental policy and politics can be utilised for this context. 相似文献

Scientists are increasingly using Twitter as a tool for communicating science. Twitter can promote scholarly discussion, disseminate research rapidly, and extend and diversify the scope of audiences reached. However, scientists also caution that if Twitter does not accurately convey science due to the inherent brevity of this media, misinformation could cascade quickly through social media. Data on whether Twitter effectively communicates conservation science and the types of user groups receiving these tweets are lacking. To address these knowledge gaps, we examined live tweeting as a means of communicating conservation science at the 2013 International Congress for Conservation Biology (ICCB). We quantified and compared the user groups sending and reading live tweets. We also surveyed presenters to determine their intended audiences, which we compared with the actual audiences reached through live tweeting. We also asked presenters how effectively tweets conveyed their research findings. Twitter reached 14 more professional audience categories relative to those attending and live tweeting at ICCB. However, the groups often reached through live tweeting were not the presenters’ intended audiences. Policy makers and government and non‐governmental organizations were rarely reached (0%, 4%, and 6% of audience, respectively), despite the intent of the presenters. Plenary talks were tweeted about 6.9 times more than all other oral or poster presentations combined. Over half the presenters believed the tweets about their talks were effective. Ineffective tweets were perceived as vague or missing the presenters’ main message. We recommend that presenters who want their science to be communicated accurately and broadly through Twitter should provide Twitter‐friendly summaries that incorporate relevant hashtags and usernames. Our results suggest that Twitter can be used to effectively communicate speakers’ findings to diverse audiences beyond conference walls. 相似文献

This article describes and assesses the impact of oil spillage and oil well fires on Kuwait and its surroundings. The marine
ecology of the Arabian Gulf is shown to be relatively resistant to damage from oil spillage. The risks of the contamination
of thermal desalination plants by oil and oil products are assessed, and remedies are suggested. Air pollution from burning
oil wells is described and its consequences are predicted.
Editor’s note: Professor Hosny Khordagui worked as a research scientist at the Environmental and Earth Science Department of the Kuwait
Institute for Scientific Research. The Iraqi invasion of Kuwait on August 2, 1990, led to the permanent loss of most of his
data, research reports, and laboratory equipment, and Prof. Khordagui was constrained to live under the Iraqi occupation for
a few weeks. His article “A Conceptual Approach to the Selection of a Control Measure for Residual Chlorine Discharge in Kuwait
Bay” will appear in a forthcoming issue ofEnvironmental Management. 相似文献
