By presenting stakeholders’ competing representations of an extraordinary geological formation, an island with a surface that is comprised of runoff from an infamous mud volcano in East Java, this article explores the communicative openings and closures that arise during an environmental disaster. A particular concern is attuning communicative practices to the diverse human and nonhuman actors that not only produce disasters but also shape our understandings and responses to disasters. Drawing on the work of Bruno Latour, this article suggests that non-anthropocentric modes of inquiry present new communicative and political possibilities for pursuing both social justice and safe environments. While this article focuses on a specific set of incidents in Indonesia, this project develops tools and perspectives that can be applied to environmental conflicts at other places. 相似文献

The main achievements of the debates on deliberative democracy and democratised science are investigated in order to analyse the reasons, meanings and prospects for a democratisation of global environmental policy. A deliberative systems approach, which emphasises the need to explore how processes in societal spheres interact to shape the deliberative qualities of the system as a whole, is adopted. Although science plays a key role in this, its potential to enhance deliberative capacity has hardly been addressed in deliberative theories. The democratisation of science has potential to contribute to the democratisation of global environmental policy, in that it also shapes the potential of deliberative arrangements in the policy sphere. Deliberative arrangements within the policy sphere may stimulate the democratisation of science to different degrees. 相似文献

示踪技术用于气体泄漏扩散模拟的多元线性回归分析 总被引:3,自引:0,他引:3
采用江苏工业学院油气储运安全综合实验模型平台,利用示踪技术(以CO2为示踪剂),模拟了有害气体瞬时泄漏扩散的整个过程.并结合多元线性回归分析的基本方法,定量分析了气体泄漏扩散过程,建立了多元线性回归模型,初步确定了泄漏气体浓度与相关物理量的变化关系,在此基础上得到了2个定量评价指标:确定性系数R=0.991,相关系数r=0.995.研究表明,在实验室建立的试验模型能较好地反映现实情况,模型仿真度较高,数据拟合效果较好.研究可为评价模型的相似性提供理论参考,对有害气体泄漏扩散事故应急救援、实施有效的现场控制,具有一定的科学参考价值. 相似文献

为了研究纳米颗粒通过眼部暴露后进入体内的路径及在体内的分布和代谢情况,实验采用近红外长余辉纳米探针作为示踪剂,对小鼠进行眼部暴露,随后利用活体成像技术观察其进入小鼠体内的过程及分布情况,于暴露第4天收集代谢产物,第7天取重要脏器和血液,并检测纳米探针的存在情况.结果显示纳米探针可由眼经口腔进入胃肠道中,并且纳米颗粒暴露4天后在小鼠的粪便中检测到强荧光信号,而尿液中的荧光信号较弱,暴露7 d后在小鼠的眼睑结膜、胃及眼球中检测到强荧光信号,而其余器官的荧光信号较弱.这表明通过眼部暴露后,纳米颗粒主要分布在眼和消化系统中,最后大部分经消化系统代谢. 相似文献

Fungi are undoubtedly important for ecosystem functioning; however, they have been omitted or given scant attention in most biodiversity policy documents, management plans, and formal conservation schedules throughout the world. This oversight may be due to a general lack of awareness in the scientific community and compounded by a scarcity of mycology‐associated curricula at the tertiary level and a lack of mycologists in research institutions. Although molecular techniques advance the systematic cataloging of fungi and facilitate insights into fungal communities, the scarcity of professional mycologists in the environmental sciences hampers conservation efforts. Conversely, citizen science initiatives are making significant contributions to the mycology discipline by increasing awareness and extending the scope of fungal surveys. Future research by professional and amateur mycologists into the distribution of fungi and their function in ecosystems will help identify wider and more effective conservation goals. 相似文献

Reports of the damage from wolf attacks have increased considerably over the last decade in Georgia (in the Caucasus). We interviewed locals about this problem in two focal regions: the Lanchkhuti area (in western Georgia) and Kazbegi District (in eastern Georgia) where livestock numbers had increased by an order of magnitude owing to dramatic shifts in the local economies over the last decade. This coincided with expanding habitats for wolves (abandoned plantations, for example). We found that the perceived damage from wolves was positively correlated with a poor knowledge of wolf habits and inappropriate livestock husbandry practices. Our results suggest a loss of traditional knowledge contributes strongly to the wolf–human conflicts in Georgia. Restoring traditional, simple but good practices—such as protecting herds using shepherd dogs and introducing bulls into the herds—can help one solve this problem.

随着我国经济社会的不断发展,水资源不足和水质污染引起的水危机已经成为许多地区可持续发展中的重要制约因素。在这种背景下,为了平衡环境、社会和经济多元利益,寻求先进的法律机制来调节平衡、保护流域生态环境、促进流域的可持续发展已成为一种共识。开展流域水资源生态补偿是实现流域上下游之间等相关方利益公平的关键所在。但由于我国缺乏生态补偿立法和相应的制度安排,流域水资源生态补偿目前仍面临许多问题:我国流域水资源生态补偿进展缓慢、法律制度滞后、部分法律法规彼此之间矛盾和相互冲突、流域水资源生态补偿的法律制度缺位、立法模式不适合当今流域生态环境问题解决等。本文通过对我国有关涉水法律中存在问题的分析,提出一些有关流域水资源生态补偿法律制度建设和完善的对策,以期对中国流域水资源生态补偿的推进和进一步实现水资源的可持续利用有所帮助。 相似文献

Green shipping practices in the shipping industry: Conceptualization, adoption, and implications 总被引:1,自引:0,他引:1

There have been increasing concerns about the adverse impacts on the environment caused by cargo movement in international trade. Different stakeholders ranging from shippers and carriers to government bodies and international communities have expressed worries about the environmental impacts brought by shipping related activities. The pollution and waste created in the shipping processes have imposed environmental burdens and accelerated resource depletion. The situation is set to worsen in the face of intensifying trade globalization, which has contributed to sustained growth in international shipping activities. To help protect the environment, many shipping firms have taken the initiative to find ways to lessen the environmental damage of their operations while enhancing their performance. The objective of this study is to examine the environmental awareness and the environmental measures taken in the shipping industry. We propose a conceptual framework for evaluating green shipping practices and develop several propositions stating the conditions under which shipping firms would behave in an environmentally responsible manner. We conclude with managerial and policy implications of the conceptual framework to promote green shipping practices in the shipping industry. 相似文献
