Susan Xue 《Journal of Government Information》2004,30(1):87-109
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

在实际语文教学中,教学目标的陈述普遍存在一定程度的含糊性和随意性。导致这一问题的原因较为复杂,语文教师陈述教学目标缺乏科学理论的指导无疑是其中一个重要原因,因此,从理论上探讨语文教学目标陈述问题十分必要。现代科学心理学有关教学目标陈述的理论主要包括分类分层陈述理论、行为目标理论和行为样品理论。依据这些理论,语文教师在设计教学目标时应该针对学生的语文学习结果分类陈述,针对学生的语文学习过程分层陈述,针对学生的言语行为规范陈述。 相似文献

This study surveys transitions specific to parents of children with autism spectrum disorder (ASD), examines how aspects of relational turbulence vary based on the type of transition experienced, and explores the transition processing activities couples use to navigate marital transitions in this context. The study examined the transition experiences of 298 parents of children with ASD who were currently married. Participants detailed an important transition throughout the life span of their child with ASD using open-ended questions. They completed scales assessing qualities of the relationship during the transition and transition processing communication used to navigate the experience. Results demonstrate significant differences in experiences of relational turbulence based on the type of transition described. In particular, the initial diagnosis received the highest ratings for transition magnitude and relational turbulence compared to other common transitions. Engagement in transition processing communication predicted relational uncertainty and facilitation from a partner, which predicted relational turbulence. 相似文献

This paper analyses the publication patterns of researchers in the field of applied sciences at Universities of Technology in South Africa. Aspects investigated include publications in SCOPUS-listed journals; number of citations and countries of publication. Collaborative research patterns at national and international levels were also investigated. A bibliometric analysis approach was followed using SCOPUS as the main source of data and analysing the articles published in selected applied science disciplines. Results show that researchers in the field of applied sciences in universities of technology have increased their number of publications over the past 10?years and are also working in conjunction with other researchers both nationally and internationally. The analysis is an important addition to the field in South Africa which helps in measuring how institutions are positively responding to government incentives in research. The results are also important to information professionals who are increasingly playing an important role in research impact assessments. 相似文献
