As the People's Republic of China plays an increasingly important role in international politics and trade, countries with economic interests there find they need to know more about this nation. Access to primary information sources, including official statistics from China, however, is very limited, as little exploration has been done into this closely controlled repository of information. This study explores major current statistical sources in China through examining (a) the statistical system in Chinese government, (b) the mechanism of statistical data collection, and (c) what statistical information is currently available in both print and electronic format and at what level. It shows that a wealth of statistical information does exist in China, it is systematically compiled, and it is available, although not conveniently, to the public through various channels. This study can serve the need for China's data from the academic and business communities, contribute to a better understanding of China's statistical system, and serve as a collection tool for academic, public, and corporation libraries as well. 相似文献

随着文化产业的快速发展,文化金融成为新兴的研究领域。本文选择2002-2016年CSSCI数据库收录的文化金融相关研究文献,运用词频统计法、可视化知识图谱法、内容分析法等多种文献计量研究方法全面分析国内有关金融支持文化产业发展的研究现状。研究发现:现阶段有关金融支持文化产业发展的研究文献逐年增加,分布期刊和研究机构众多,研究范围较广,研究内容包含国际经验比较、经验分析和实证分析;但目前该领域的研究主题相对分散,研究不够深入,缺乏微观数据支撑和模型研究,缺乏构建金融支持体系操作层面的分析,缺乏对具象产业的差异化分析,这些是未来进一步研究的方向。 相似文献

Test security is not an end in itself; it is important because we want to be able to make valid interpretations from test scores. In this article, I propose a framework for comprehensive test security systems: prevention, detection, investigation, and resolution. The article discusses threats to test security, roles and responsibilities, rigorous training for everyone involved in testing, and an evaluation of current practices in test security. I call on everyone responsible for testing programs—the Association of Test Publishers, Council of Chief State School Officers, National Council on Measurement in Education, U.S. Department of Education, and state assessment program managers, their vendors, and the research community—to collaborate on guidelines and practices for security violation prevention, detection, investigation, and resolution. 相似文献

AbstractThis article reports the results of a quantitative and systematic analysis comparing usage rates between English-language and French-language e-monograph titles at Laurentian University, Canada. Full-text viewings were collected as usage metrics. English-language e-monographs exhibited medium strength linear relationships between collection size and usage. On the other hand, French-language e-monographs exhibited weak linear relationships between collection size and usage. The French-language e-monograph collection experienced a higher rate of full-text use, relative to size. The cost-per-viewing ratio for the English-language e-monograph collection was higher than those that calculated for the French-language collection. 相似文献
