This paper explores ways to enhance overseas Chinese graduate employability by taking Finnish-educated Chinese students/graduates as an example. In so doing, it understands that graduate employability development is a joint effort of multiple stakeholders including students, graduates, academics, program coordinators, employers, and policymakers. Accordingly, it provides arguments and suggestions for how to enhance the employability of these graduates in terms of the labor market context, employers’ beliefs and actions, the responsibilities of higher education institutions, and student/graduate commitment. It also points out two major challenges faced by overseas Chinese graduates as well as their educational providers, which are linked respectively to gaps between what graduates acquire in higher education and what is required in the labor market, as well as gaps from the employers’ perspective: areas where employers need to understand more about universities and catch up with new ideas generated by them.  相似文献

我国中长期教育改革与发展规划纲要(简称纲要)的研制工作,已经进行了很长时间,今年应该面世了。对这个纲要,政府很重视,社会很期待,公众很关注。人们都想知道,这个纲要将给我们传递什么信息,我们将怎样看待这个纲要?其实,最重要的是:纲要如何表达中国教育发展的思路?政府将采取哪些措施促进中国教育的发展?我认为,至少需要从如下几个方面思考和看待这个重要的文件。  相似文献

近期部分收入差距拉大的问题引起人们的普遍重视,有的人甚至认为邓小平同志的“先富”带共富的思想过时了甚至失误了。笔者认为,邓的这一思想并没过时,仍然社会主义初级阶段的主导思想。目前的部分收入差距过大现象的产生有其客观现实的原因,与邓小平同志的“先富”带“共富”的思想并没有直接的因果关系。  相似文献

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献

This study compares the job satisfaction, job burnout and organizational cynicism of 233 early childhood teachers, 141 female and 92 male, with special attention to gender differences. Data were collected using a personal information form, Job Satisfaction Scale, Maslach Burnout Inventory-Educators Survey and Organizational Cynicism Scale, and the data were analyzed via independent-samples t-testing and one-way between-groups MANOVA. Significant differences between the male and female teachers were found across all three of the variables of interest, with the males having a higher level of organizational cynicism and lower mean job satisfaction. Also, males’ job burnout was higher than females’. However, the magnitude of these differences was medium only in the case of job satisfaction, with all other effect sizes being small.  相似文献

Objective: To study the regulation of blood pulse volume via photoplethysmography (PPG) signal detected from toe, while the lower limb is passively raised in different height positions. Methods: Use a modified non-invasive PPG technique to detect the blood pulse signal on toe with infrared (IR) photo sensor. A protocol consisting of two postures, i.e., supine and 45° reclining, was designed to conduct laboratory trial in this study. During the period of performing the protocol of these postures, the lower limb was passively raised from the heights of 10 cm to 60 cm randomly and individually with sponge blocks underneath the foot. Results: In the supine posture, the higher the foot was passively raised, the more the blood PPG signal decreased. In the 45° reclining posture, the blood PPG signal increased at the beginning and then decreased in the foot height position from 10 cm to 60 cm. In both postures the normalized AC signal changes significantly while the normalized DC signal changes little. Conclusion: The toe PPG signals can obviously indicate the regulated blood volume change with the designated postural procedures due to the heart level position.  相似文献
