通过检索庐山研究的电子文献,分析表明1994年后为庐山研究的高峰阶段。核心刊物发表的庐山研究文献相对较少,所占比例且呈逐渐下降的趋势。庐山研究文献的平均合作度和合著率较低,论文第一作者的分布具有广泛性和不均衡性特征,江西省由于地域上的优势而居发文量首位。科研院所是庐山研究的核心力量,庐山管理局以其优越的区位关系占据发文机构的首位。活跃作者群呈现出地域衰减规律,以江西九江为最高,逐次向省内的南昌以及周边省份扩散衰减。庐山研究文献的主题分布依次为文化景观类、旅游类、生物类、地质地貌类和生态环境类。庐山的研究应着力于建立的科学研究体系、培育和谐的研究群体和注重研究方法的创新。 相似文献

This paper examines how scientific literature and policy documents frame the ecosystem concept and how these frames have shaped scientific dialogue and policy making over time. This was achieved by developing a frame typology, as a basis for organizing relevant value expressions, to assess how different frames have altered perspectives of the ecosystem concept. The frame typology and analysis is based on a semi‐grounded and longitudinal document analysis of scientific literature and policy documents using the ecosystem concept. Despite changing discourses and public priorities (e.g., cultural constructs of biodiversity) both science and policy documents are characterized by stable value systems that have not changed substantially since the 1930s. These value systems were defined based on ethical principles that delineate 6 core frames: humans first, dual systems, eco‐science, eco‐holism, animals first, and multicentrism. Specific crises (e.g., climate change) and cross‐disciplinary uptake and re‐uptake of, for example, the ecosystem services concept, have brought new perspectives to the forefront of public discourse. These developments triggered changes in the core frames that, rather than being value based, are based on how the ecosystem is conceptualized under fixed value systems and over time. Fourteen subframes were developed to reflect these longitudinal changes. There are as such clear framing effects in both scientific literature and in policy. Ecosystem research is for instance often characterized by unstated value judgments even though the scientific community does not make these explicit. In contrast, policy documents are characterized by clear value expressions but are principally management driven and human centered. 相似文献

Due to growing environmental concern and increasing awareness among customers, reverse supply chain (RSC) has received much attention among researchers and practitioners. Therefore it is necessary to provide a comprehensive list of references for other researchers (or readers), who are interested in RSC research to help stimulate further interest. In this paper, we present classification schemes and a simple analysis for the reverse supply chain. This literature review was mainly based on journal articles but also included web based documents, conference materials, working papers, etc. A total of 543 articles were reviewed, of which 506 were published between 1967 and 2008 from 100 reputed international journals. Based on the literature review carried out and the nature of research observed in RSC, we have introduced two classification schemes to systematically organise the published articles. The first classification scheme is based on the content related issues on RSC and the second one is based on the solution methodology followed by the researchers. These classification schemes indicate that there is considerable research potential for RSC. The results also show that there is strong growth in RSC research. 相似文献

ABSTRACT: Water resources professionals are being increasingly called upon to address complex problems which require the interaction of several individuals operating as a planning or implementation team. Education for water resources professionals must move to meet the demands of this mode of operation. To best prepare the student, educational programs must focus not only on technical competence but must also incorporate concepts of cooperative problem solving with individuals from a diversity of backgrounds as a part of the curriculum. Among strategies which may work are academic requirements outside of the technical specialty, modification of existing course materials, and inclusion of outside faculty as a part of departmental curriculum preparation. 相似文献
