为完善安全科学原理体系,指导安全科学原理研究工作的开展,从方法论角度探讨安全科学原理的研究。结合安全科学、安全科学方法论与方法学,给出安全科学原理及安全科学原理研究方法论的定义,并从方法的角度对安全科学原理进行分类,阐明不同存在状态的安全原理的研究取向,确定安全科学原理的结构三要素。提出以安全现象-安全规律-安全原理为发展主线的第1类未知安全科学原理的一般构建步骤,以及以并列-比较-假设-检验为主线的第2类未知安全科学原理构建步骤,并建立安全科学原理动态研究的范式体系。研究结果使安全科学原理研究的层次思路系统化,并有益于指导安全原理研究工作的进行。 相似文献

Abstract: Debate about the nature and appropriateness of advocacy by environmental scientists is important—it represents understanding the role of these citizens in our society. Much has been written about advocacy by scientists, and that literature describes substantial diversity in reasons why advocacy by scientists is or is not appropriate. Despite the nature of this literature there has been no comprehensive, systematic review of why some favor and others oppose advocacy by environmental scientists. Through a literature review we catalogued, categorized, and critiqued the arguments used for and against the appropriateness of advocacy by environmental scientists. Most arguments, whether for or against advocacy, are characterized by some significant deficiency. From our analysis of the literature an argument emerges that to date has never been fully articulated: that advocacy is nearly unavoidable, and that scientists, by virtue of being citizens first and scientists second, have a responsibility to advocate to the best of their abilities, to improve their advocacy abilities, and to advocate in a justified and transparent manner. We also discuss the meaning and relevance of advocacy being justified and transparent. We suggest scientists expend their efforts to better understand what constitutes appropriate advocacy and spend less effort pondering whether they should advocate . 相似文献

Abstract: Funding for conservation is limited, and its investment for maximum conservation gain can likely be enhanced through the application of relevant science. Many donor institutions support and use science to pursue conservation goals, but their activities remain relatively unfamiliar to the conservation‐science community. We examined the priorities and practices of U.S.‐based private foundations that support biodiversity conservation. We surveyed 50 donor members of the Consultative Group on Biological Diversity (CGBD) to address three questions: (1) What support do CGBD members provide for conservation science? (2) How do CGBD members use conservation science in their grant making and strategic thinking? (3) How do CGBD members obtain information about conservation science? The 38 donor institutions that responded to the survey made $340 million in grants for conservation in 2005, including $62 million for conservation science. Individual foundations varied substantially in the proportion of conservation funds allocated to science. Foundations also varied in the ways and degree to which they used conservation science to guide their grant making. Respondents found it “somewhat difficult” to stay informed about conservation science relevant to their work, reporting that they accessed conservation science information mainly through their grantees. Many funders reported concerns about the strategic utility of funding conservation science to achieve conservation gains. To increase investment by private foundations in conservation science, funders, researchers, and conservation practitioners need to jointly identify when and how new scientific knowledge will lower barriers to conservation gains. We envision an evolving relationship between funders and conservation scientists that emphasizes primary research and synthesis motivated by (1) applicability, (2) human‐ecosystem interactions, (3) active engagement among scientists and decision makers, and (4) broader communication of relevant scientific information. 相似文献

以经典Mincer收入方程为基础。通过引入教育、经验与区域变量。对1990年和2000年我国人力资本收益率及其影响因素进行估计。形成了关于我国人力资本发展阶段特征的基本判断。模型结果支持了正规教育对人力资本的影响由线性向非线性的变化。并且在平均收益率方面中等教育有着潜在优势;在经验因素中。工作前的经验比工作后的经验对收入影响更显重要;东部地区人力资本的形成与其他地区存在显着的差异。而东部以外的地区之间人力资本形成模式差异则不明显。 相似文献

农业生态经济系统的规划思路 总被引:2,自引:0,他引:2
本文旨在依据生态学的“循环再生整体协调”,经济学的“平衡原理”,系统科学的“整体优化原则”等的一致性内核,围绕人类经济活动与自然生态之间相互发展的关系,经过对农业中出现的一系列严重问题的分析,提出在我国建立以现代科技支撑的农业生态经济系统的规划理论思路,它与现有的规划理论方法相比,具有明显的可操作性和适用性。 相似文献

In response to extreme events, researchers have recognised the convergence of volunteers, emergency responders, and other individuals and organisations. In 2000, geographer Paul Routledge presented the concept of convergence spaces as a theoretical means to explain social movements. In applying this concept, this paper explores the geographic space in which organisations and individuals converged immediately following the 11 September 2001 attacks on the World Trade Center. The paper begins to answer the question of whether there were in fact any patterns of convergence among the locations utilised by organisations responding to the attacks. Using data collected from field documents, these geographic locations are mapped over 12 days to help identify possible patterns of clustering. Results of this analysis will begin to provide researchers, policy makers and practitioners with a better understanding of how emergency response evolves geographically following an event. 相似文献
