Why we need theory in the organization sciences

To make the case that theory is a necessary part of research in the organization sciences, I develop three lines of argument. In the first, drawing upon Staw and Sutton's (1995, “What theory is not” Administrative Science Quarterly, 40, 371–384) classic piece, I outline the boundaries of theory and, using a recently published empirical article as an example, demonstrate how research based on literature references and line‐and‐box diagrams instead of explanatory theory can make only a limited contribution to the literature. I next discuss more generally the pitfalls of conducting research without first developing theory, citing the example of malaria. In the final section of the article, I defend the role of theory‐review articles, such as those published in the Academy of Management Review, and illustrate (again by reference to an example) how such articles are critical to advancing organizational research.

马克思恩格斯关于依靠科学技术发展生态农业的思想及其当代启示

马克思恩格斯虽然没有专门论述生态农业的著作,但在他们的理论文本中蕴涵着深刻的生态农业思想。在马克思恩格斯看来,依靠技术,改良耕作方法,可以保持和改良土质;通过在农业中利用现代科学技术能够提高农业生产率,促进农业发展。马克思恩格斯关于依靠科学技术发展生态农业的思想,为我国的农业发展指明了方向。     

化学科学研究与环境保护的机理相关性

环境问题已经引起世界各国政府和全社会的广泛关注。环境保护是利用环境科学的理论和方法,协调人类与自然环境的关系,以保护和改善环境的一切人类活动的总称。本文将首先分析由化学物质引起环境污染的案例,进而给出进行环境友好型的化学科学研究的方法及其重要性,以及通过化学科学的不断发展来解决业已存在的环境污染问题。     

地震新闻报道同质化对策研究

在深入分析地震新闻报道同质化特征及其原因的基础上,本文认为有效解决地震新闻报道同质化的途径有三：一是相关部门要转变思想,明确地震新闻在地震科普中的重要作用;二是新闻媒体要转变地震新闻报道方式,追求差异化报道;三是要引导受众转变新闻消费观念,以刺激新闻生产者的积极性。

Integrated coastal management: the challenge of transdisciplinarity

The Euroconference on Coastal Management Research held in San-Feliu de Guixols, Spain, in December 1997 brought together scientists from a great variety of disciplines in the natural and social sciences, in a search for modes of transdisciplinary cooperation in the context of integrated coastal management. During the conference the participants discussed which interactions among disciplines are required for different coastal issues. Discussion groups each focused on a particular type of coastal environment, characterized by a particular type and degree of development. The group discussions were inspired by background papers which were prepared for this purpose by invited speakers. A selection of these background papers were redrafted on the basis of the conference outcome, and are published in this issue of theJournal of Coastal Conservation. The reports of the discussion groups are published in a conference proceedings booklet issued by EMAPS (1998), the European Polar and Marine Sciences Secretariat. A synthesis of ideas on the challenge of transdisciplinarity, expressed during the discussion group sessions, is presented in this introduction. The statements reflect opinions or suggestions which received broad support from the participants; they should not be taken as proven knowledge.

Prevalence and perspectives of illegal trade in cacti and succulent plants in the collector community

Although illegal wildlife trade (IWT) represents a serious threat to biodiversity, research into the prevalence of illegal plant collection and trade remains scarce. Because cacti and succulents are heavily threatened by overcollection for often illegal, international ornamental trade, we surveyed 441 members of the cacti and succulent hobbyist collector community with a mixed quantitative and qualitative approach. We sought to understand collector perspectives on the Convention on the International Trade in Endangered Species of Wild Flora and Fauna (CITES) and on the threats IWT poses to cactus and succulent conservation. Most respondents (74% of 401 respondents) stated that illegal collection in cacti and succulents represents a “very serious problem” and that the problem of wild plant collection is increasing (72% of 319 respondents). Most forms of illegal collection and trade were seen as very unacceptable by respondents. Self-reported noncompliance with CITES rules was uncommon (11.2% of 418 respondents); it remains a persistent problem in parts of the cacti and succulent hobbyist community. People engaging in rule breaking, such as transporting plants without required CITES documents, generally did so knowingly. Although 60.6% of 381 respondents regarded CITES as a very important tool for conservation, sentiment toward CITES and its efficacy in helping species conservation was mixed. Collectors in our survey saw themselves as potentially playing important roles in cactus and succulent conservation, but this potential resource remains largely untapped. Our results suggest the need for enhanced consultation with stakeholders in CITES decision-making. For challenging subjects like IWT, developing evidence-based responses demands deep interdisciplinary engagement, including assessing the conservation impact of species listings on CITES appendices.     

基于指标规范值的地表水水质的模糊综合评价

传统的模糊综合评价法用于地表水水质评价,当指标数较多时需要设计很多隶属函数,设计和计算工作量皆很大,实际使用不便。在设定指标参照值和规范变换式基础上,将指标按各级标准规范值相近程度进行适当分类,只需分类设计隶属函数即可,大幅减少了计算工作量,使模糊综合评价法应用于地表水水质评价变得简化。
