运用极值熵值法以及耦合协调度模型,以2000—2016年可获得的相关数据为基础,对云南省科技进步-经济发展系统耦合协调度进行纵向研究,对云南省与我国东中西部的浙、苏、湘、鄂、贵、桂6省(区)科技进步-经济发展系统耦合协调度进行横向对比,对云南省内16州市科技进步-经济发展系统耦合协调度进行内部分析。研究发现:从纵向看,云南省科技进步、经济发展水平稳步上升,科技进步与经济发展耦合协调度不断上升;从横向看,云南省科技进步水平、经济发展水平、科技进步与经济发展协调度低,科技进步与经济发展的耦合度较高;从云南省内各州市看,科技进步-经济发展系统耦合度分布较为均匀,协调度昆明一枝独秀,其余州市处于中度协调水平以下;专利对云南省科技进步水平的提高相对更重要。据此,从认识观、创新驱动、经济跨越式发展、区域科技经济增长极等方面提出相关政策建议。  相似文献

本研究通过引入点格局分析方法,以湖南省2013年专利数据为研究样本,基于细粒度的专利地址空间数据,分析了湖南省创新活动空间点格局及其影响因素。研究发现:湖南省创新活动呈现以长株潭地区为中心,向外逐渐递减的“核心-边缘”空间异质性结构,且创新活动空间集聚的最佳地理尺度在20km-21km之间。同时创新活动空间分布强度受到每平方公里GDP和最近道路距离两个因素的显著影响,且由于经济活跃度非连续性的存在造成了每平方公里GDP对创新活动的差异影响。文章认为鼓励创新发展的政策应充分考虑区域经济发展的不平衡性,在区域经济发展水平较高的地区,应该加大对自主创新的激励,而在经济不发达地区则强调道路通达性对加强创新溢出和创新融合的影响。  相似文献

为科学规划盘州市社会经济发展任务,实现国土空间有序开发与区域生态、经济、社会和谐可持续发展目标。以贵州省喀斯特地貌广泛发育的盘州市为研究区,运用RS与GIS空间地理信息技术,整合社会与经济发展数据,按照《市县经济社会发展总体规划技术规范与编制导则(试行)》中三类空间划分方法,评价盘州市空间开发适宜性。研究结果表明:盘州市石漠化分布较广,面积达1059. 90 km~2,已发生石漠化等级主要以轻度、中度为主;盘州市适合开发面积共占国土面积26. 08%,市域内土地资源有限且土层浅薄,区域发展潜力小;参考石漠化综合防治治理模式与地方发展实际,提出在轻度以下石漠化-适宜及较适宜开发地区发展刺梨、核桃、软籽石榴等为主的特色规模种植业,特色产品加工业、战略新兴产业、新型建材等产业,在中度以上石漠化-适宜及较适宜开发地区,禁止大规模毁林开山等非国家重大基础设施、非重大民生保障项目建设开发行为等决策建议。  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

Ajoint study by Prof. ZHANG Zhibin from the CAS Institute of Zoology and his co-workers from Norway, US and Swiss have indicated that historical outbreaks of migratory locusts in China were associated with cold spells, suggesting that China's projected climate warming could decrease the pest's numbers. The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.  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

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

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP.  相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence  相似文献
