影响高等教育规模的主要因素及其协整关系——基于时间序列数据的分析   总被引：7，自引：0，他引：7  

毛建青 《北京师范大学学报(社会科学版)》2009,(2)

从1999年开始,我国高等教育规模迅速扩大,2007年高等教育毛入学率已达23%。同时,大学生就业难、文凭贬值等问题日益凸显,据此引发了人们对教育"过度"还是"不足"的争论。因此,分析我国历年来高等教育规模及其主要影响因素,并探寻它们之间的协整关系就显得非常有意义。在以往的相关研究中,学者们用最小二乘法实证分析历年高等教育规模及其影响因素之间的关系,但容易出现"伪回归"。运用动态计量经济学中的协整理论进行分析则可以解决这个问题。协整计量的结果发现,高等教育规模与四个影响因素之间确实存在稳定的长期均衡关系,其影响系数从大到小依次为总人口数、恩格尔系数、GDP发展水平和第三产业占GDP的比重。  相似文献

ISM-CMAP-Combine (ICMC) for hierarchical knowledge scenario in quality engineering education     

R. K. Upadhyay  S. K. Gaur  V. P. Agrawal  K. C. Arora 《European Journal of Engineering Education》2007,32(1):21-33

Quality assurance in engineering education is a multifaceted problem further augmented by the stakeholders of engineering education. Students, parents and employers are rightfully questioning the quality of the curriculum, the instructional delivery, the learning environment, accessibility to learning technologies and equipment, employability as well as the possibilities of lifelong learning and the improvement of knowledge (Karapetrovic 2002 Karapetrovic, S. 2002. Why and how to develop a meaningful quality assurance system in engineering schools. Int. J. Engg. Educ, 18(3): 285–294. [Web of Science ®] [Google Scholar]). The purpose of the study is, therefore, to identify the parameters that influence the quality of an engineering education system and develop an integrated model of hierarchical structuring and a concept map for pre-identified concept elements through a process of iterative-interactive consensus-driven methodology, as advocated by second-generation system design paradigm for evolving knowledge scenario of concepts related to quality engineering education.  相似文献

Knowledge maps: A systematic literature review and directions for future research     

《International Journal of Information Management》2016,36(3):451-475

ContextNowadays the concept of knowledge mapping has attracted increased attention from scientists in a variety of academic disciplines and professional practice areas. Among the most important attributes of a knowledge map is its ability to increase communication and share common practices across an entire organisation. However, despite being a promising area for research, the knowledge maps community lacks a widespread understanding of the current state of the art.ObjectiveThe objective of this article is to explore the world of knowledge mapping by reviewing and analysing the current state of research and providing an overview of knowledge mapping’s concepts, benefits, techniques, classifications and methodologies, which are precisely reviewed, and their features are highlighted. In addition, we offer directions for future research.MethodBased on the systematic literature review method this study collects, synthesises, and analyses numerous articles on a variety of topics closely related to a knowledge map published from January 2000 to December 2013 on six electronic databases by following a pre-defined review protocol. The articles have been retrieved through a combination of automatic and manual search, hence extensive quantitative and qualitative results of the research are provided.ResultsFrom the review study, we identified 132 articles addressing knowledge maps that have been reviewed in order to extract relevant information on a set of research questions. We found a generally increasing level of activity during this 5-year period. We noted that while existing research covers a large number of studies on some disciplines, such as systems and tools development, it contains very few studies on other disciplines, such as knowledge maps adoption. To aid this situation, we offer directions for future research.ConclusionsThe results demonstrated that a knowledge map is an imperative strategy for increasing organisations’ effectiveness. In addition, there is a need for more knowledge maps research.  相似文献
