基于CIM的电力信息管理系统,可以解决电力系统中数据一致性问题:使电力企业各部门、各业务使用的数据保持统一性、完整性、可靠性。电力系统信息管理涉及到不同的软件平台、不同的应用软件、不同的应用模式以及不同的数据类型和格式。不仅仅是将多个应用系统连接起来,而且可以将应用软件的数据交换标准化,以及根据业务处理需求协调不同的应用。 相似文献

新古典主义经济学和凯恩斯主义经济学对就业问题都提出了各自的理论见解.但是,由于这些理论分析范式各异,欠缺合理的对话平台.本文试图根据相关文献中"模型构建不同完成条件"构建一共同分析框架,对这些理论的代表性失业模型进行重新阐释和对比.通过分析比较发现,这两大理论体系关键区别之一在于对定价行为的看法,前者将厂商视为"价格的接受者",而后者将厂商视为"价格的制定者". 相似文献

Culturally responsive instruction has the advantage of helping diverse students make academic gains. The purpose of this study was to investigate the effects of culturally infused mathematics lessons on the academic achievement of five middle school Latino students with specific learning disabilities in a resource classroom. We used an ABACACA multiple treatment reversal design, in which two forms of culturally responsive instruction (B) and its modification (C) were compared with the traditional instruction (A). The results of the study indicated that the modified culturally responsive mathematics instruction (C) was associated with increases in positive gains in participants' daily mathematics quizzes. Limitations and implications are discussed in relation to culturally responsive instruction for middle school Latino students with specific learning disabilities. 相似文献

An "optical space-time coding method" was applied to microfluidic devices to detect the forward and large angle light scattering signals for unlabelled bead and cell detection. Because of the enhanced sensitivity by this method, silicon pin photoreceivers can be used to detect both forward scattering (FS) and large angle (45-60°) scattering (LAS) signals, the latter of which has been traditionally detected by a photomultiplier tube. This method yields significant improvements in coefficients of variation (CV), producing CVs of 3.95% to 10.05% for FS and 7.97% to 26.12% for LAS with 15 μm, 10 μm, and 5 μm beads. These are among the best values ever demonstrated with microfluidic devices. The optical space-time coding method also enables us to measure the speed and position of each particle, producing valuable information for the design and assessment of microfluidic lab-on-a-chip devices such as flow cytometers and complete blood count devices. 相似文献

As a compulsory course at universities throughout the Chinese Mainland, ideo-political education aims to safeguard university
students’ political loyalty to the Communist Party. By employing a qualitative research method, this study investigated a
renowned comprehensive university in southern China. The case study found that students expressed strong resistance to compulsory
ideo-political courses. From the outset, teachers had to work to change students’ overwhelmingly negative perceptions of ideo-political
education. Informants found that they could not attract student interest if they only strictly followed the state designed
textbook, and therefore chose instead to cover topics they found more interesting and to discuss social issues in their lectures.
However, the new curriculum reform and teaching quality assurance mechanism placed further restrictions on teaching and learning.
Whether teachers could maintain enough autonomy to make the above adjustments depended on the understanding and support of
key senior academics. 相似文献

This paper examines the impact of reform policies on the work of Chinese teachers. It explores the policy context in which a fragile teaching profession attempts to develop and discusses the dynamics of interacting societal forces that have created the dilemmas for the teachers. The authors argue that while the continual implementation of reform policies has fostered a new outlook in Chinese schools, calls for profound change in schooling have caused much anxiety among teachers. The teachers' anxiety stems from the incongruence between their professional outlook, which is intimately linked to student academic achievement, and the dictates of state reform measures, which seek to broaden the conception of education to include other areas of human development. Throughout the years of reform, teachers have had to stretch their professional capacity in order to satisfy competing demands engendered by reform measures and educational reality. It is in the tensions caused by the implementation of reform policies that the humanism of teacher professionalism is magnified. In this paper, the authors discuss the educational and social issues that surround the teachers' preference for conventional practices. 相似文献

This article examines how commodification and consumerism have sharpened the discourse of internationalization in Taiwan’s higher education. Given the strong sense of crisis in the less prestigious universities, this article argues that internationalization is only a means to survive instead of a pursuit of excellence to these universities. This empirical finding leads us to rethink the concept of internationalization and its relevance and application to Taiwan’s higher education. This article adopts a case study approach to investigate the practices of internationalization, including program and institutional mobility, overseas networking, curriculum design, teaching, and administrative support. The implications of these internationalization practices for sustainability and quality in higher education development are then discussed. 相似文献

This is a comparative survey study of journalists’ attitudes and perceptions concerning various types of conflicts of interest in Mainland China, Hong Kong and Taiwan. Journalists in all three regions are found to be receptive to freebies in the form of small gifts, meals and trips. However, they almost unanimously agree that monetary benefits from news sources are unacceptable. Compared with freebies, moonlighting seems to be a less serious problem in the three regions. Most journalists think that their colleagues do not commonly practice moonlighting. The journalists strongly agree that they should not solicit advertising on behalf of their employer or work for public relations firms or the government as a second job. With regard to self-censorship, journalists in the three regions unanimously agreed that softening negative coverage of key advertisers was unethical. However, there was considerable disagreement about softening negative coverage of government. The results also show that there is in general a discrepancy between the journalists’ value orientations and perceived reality, especially in Mainland China and Taiwan. 相似文献
