环境意识是环境保护的思想基础,其水平的高低直接影响着人们环保行为的自觉程度。针对珠三角沿海地区越来越严重的外来生物入侵的环境现象,本研究依据广东省惠州市博罗县为中心的公众环境意识的调查数据,就公众环境意识进行描述性分析。在此基础上利用综合得分法分析性别、文化水平、年龄这三个因素对公众环境意识的影响。结果表明,大部分公众意识或者感受到外来生物入侵现象,然而缺乏足够的环境意识水平;影响因素部分,性别对环境意识水平基本无影响;环境意识水平随文化水平的提高而提高;环境意识水平随年龄的增长而降低。认清珠三角沿海地区公众对外来生物入侵现象的环境意识影响因素,分门别类地开展有针对性的宣传与教育工作,有助于提高相关群体环境保护的意识和能力。 相似文献

环境认知、环境责任感与城乡居民的低碳减排行为 总被引：2，自引：0，他引：2
基于CGSS2010数据,建立定序逻辑斯蒂回归模型,分析城乡居民减排行为的影响因素。研究结果表明:目前我国城乡居民的减排行为总体水平较低。总体而言,环境认知(减排知识、环境污染认知、气候变化原因和危害认知、环境科技观)和环境责任感(环境问题关注度、环保责任意识、环保倾向)显著提升公众的减排行为,传播沟通(媒体接触、环保社团参与)促进公众实施更多减排行为。但这些影响因素存在显著城乡差异,与城市居民相比,农村居民的减排行为更多受到环境责任感的驱动,而环境认知、传播沟通的影响几乎不显著。此外,年龄较大者、收入较低者、教育水平高者、东部和城市居民的减排行为越积极。 相似文献

旅游情境下公众低碳旅游行为影响因素研究——以三亚游客为例 总被引：2，自引：0，他引：2
低碳旅游发展离不开社会公众的积极参与,准确把握公众在特定旅游情境下的低碳行为机理是推动旅游业低碳转型与可持续发展的重要环节。基于对三亚市过夜游客的问卷调查数据,采用结构方程模型分析方法,从微观视角对公众在特定旅游情境下的低碳旅游行为影响因素进行了研究探讨。结果表明:公众的低碳旅游行为由一般行为与积极行为两个维度构成,公众对一般行为的认知和参与度较高,对积极行为的认知和参与度偏低。比较而言,一般行为相似于公众较为熟悉的节能环保行为,易受公众环保价值观和态度的影响;积极行为需要更高的参与热情和能力,相对更易受低碳知识和旅游地低碳情境的影响。同时,社会规范与感知利益对一般和积极低碳旅游行为都具有显著影响。基于此,研究提出了一个旨在引导公众积极参与低碳旅游行为,推动低碳旅游发展的政策框架。 相似文献

企业技术创新是解决环境污染和经济增长矛盾的根本所在,成为实现环境保护和经济发展“双赢”的有效途径.政府环境规制、企业技术创新和公众环境参与是相互影响及制约的利益关系,因此,探究三方利益相关者对企业技术创新行为的影响成为学者研究的重要课题.从演化经济学的视角,运用动态演化博弈理论,构建政府、企业和公众的三方博弈模型,根据演化的仿生学研究,引入Lotka-Volterra模型求稳态均衡解,探究环境利益相关者的规制行为对企业技术创新策略的演化影响,并利用Matlab通过数值模拟进行检验.研究结果表明:环境规制与企业技术创新战略选择是一场混合战略均衡的博弈过程,企业、政府和公众的行为决策受其收益和成本的大小影响,利益相关方的环保措施在一定程度上会促进技术创新.因此,应恰当选择政府环境规制手段和强度水平,合理规划规制成本,不断提高公众环保意识,强化环境监管,促使企业以环保为己任,实施技术创新策略,减少环境污染. 相似文献

A research group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol-a chemical found in the skins of red grapes in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献
