缩短刊期的实践与效果分析 总被引：1，自引：3，他引：1
通过对《西北植物学报》变更月刊前后两年期刊的影响因子和作者群分析，结果表明：2003年《西北植物学报》变更月刊的影响因子由2002年双月刊的0．390上升到0．607，总被引频次由476提高到824；2003—2004年发表基金项目论文总数占发表论文总数的平均比例由82．25％增加到87．83％，其中国家自然科学基金、国家“973”项目、国家“863”项目、国家“九五”、“十五”项目、中国科学院创新项目等合计平均总数由2001—2002年的331项增加到846项，由占当年发表各类基金项目资助发表论文总数的64．43％增加到67．78％；发表论文第一作者为博士的人数（含在读博士生）平均占当年发表论文总数的比例由40．67％上升到45．94％，院士作者也有所增加。变更月刊两年的实践体会是：在缩短刊期之前，要分析期刊所在学科的发展趋势和期刊在全国同类期刊中所处的发展位置，在论证的基础上实施变更，不宜跟风；期刊缩短刊期以后，要进一步加强编辑出版过程的质量管理，建设网络环境下的信息管理系统，以提高编辑出版工作效率。 相似文献

2003年SCIE收录我国中英文版科技期刊的比较分析 总被引：1，自引：1，他引：1
通过对2003年被SCIE（包括SCI）收录的我国中英文版科技期刊的比较分析，占全部期刊（4497种）95．6％的中文版科技期刊（4299种）中，被SCIE（包括SCI）收录25种，只占了全部中文版科技期刊的0．58％；而仅占全部期刊（4497种）4．4％的英文版的科技期刊（198种）中，被SCIE（包括SCI）收录52种，占了全部英文版科技期刊的26．3％，即进入SCIE英文版期刊的比例数是中文版期刊的比例数的45倍。因此，中文版科技期刊比英文版科技期刊较难被国际重要的检索系统SCIE（包括SCI）收录，中文版科技期刊实施国际化较困难。最后，对中文版科技期刊如何被SCIE等国际重要的检索系统收录的实施标准和国际化问题进行了一些讨论。 相似文献

分析了2000～2002年中国农业科学论文被SCIE，EI，ISTP等国际重要检索系统收录的情况，得出了如下结论：①被国际重要检索系统收录的论文数每年都在增加，2001年增加的幅度最大。纵向增长幅度明显，横向增长幅度基本没变。②在农林牧渔部类主要学科中，农业科学的国内外检索论文总数均位居榜首，且年增长最稳定，被国际重要检索系统收录的比率最大，说明其国际交流能力较强，在国际上的影响力较大。③产出国内检索论文的能力在国内学科领域中处于领先水平（3年产出的论文数在国内40个学科中排名第8），但其产出论文的国际重要检索系统收录率远低于物理学、化学等学科，在国内学科领域还处于比较落后的局面（在国内40个学科中排名第28）。④全国各地论文的收录情况参差不齐。在分析的基础上提出了加大科研力度，产出优质科研论文；创建特色栏目打造精品期刊；找准切入点，拓宽被收录途径等措施，以提高中国农业科学论文的国际重要检索系统收录率。 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

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

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
