Empowerment or impediment? School governance in the school-based management era in Hong Kong     

Paula Kwan  Benjamin Yuet-man Li 《Asia Pacific Journal of Education》2015,35(3):319-330

Following the international trend in education towards democracy and decentralization, the Hong Kong government introduced a school-based management (SBM) system about two decades ago. It is widely recognized in the literature that decentralization, empowering school level management and marginalizing the influence of the intermediate level of governance, can result in better deployment of school resources and better meet the demands of various stakeholders. However, in the unique historical and cultural context of Hong Kong, the advantages of decentralization claimed in the literature have yet to be fully realized. This paper discusses the contextual factors affecting the implementation of SBM in Hong Kong, and examines their impact on four major stakeholders, namely the government, the principals, the teachers, and the parents in the wake of reform.  相似文献   

Reexamining the Impact of Nonnormality in Two-Group Comparison Procedures     

Yoonjeong Kang  Ming Li 《Journal of Experimental Education》2015,83(2):147-174

The authors performed a Monte Carlo simulation to empirically investigate the robustness and power of 4 methods in testing mean differences for 2 independent groups under conditions in which 2 populations may not demonstrate the same pattern of nonnormality. The approaches considered were the t test, Wilcoxon rank-sum test, Welch-James test with trimmed means and Winsorized variances, and a nonparametric bootstrap test. Results showed that the Wilcoxon rank-sum test and Welch-James test with trimmed means and Winsorized variances were not robust in terms of type I error control when the 2 populations showed different patterns of nonnormality. The nonparametric bootstrap test provided power advantages over the t test. The authors discuss other results from the simulation study and provide recommendations.  相似文献   

A Classroom Exercise to Examine the Trade‐off between Mission Capacity and Life Cycle Cost          下载免费PDF全文

Keebom Kang  Kenneth H. Doerr 《Decision Sciences Journal of Innovative Education》2015,13(1):3-20

This article presents a classroom exercise, centered on a simulation that has been used for 4 years in an MBA program to help students develop an understanding of the trade‐offs involved in managing capital assets in the public sector. Though often ignored in business schools, mission is a key criterion that must be considered when managing such assets, and acts as a surrogate for profit. The case presents a rich environment in which the impact of cost reductions (or additional investments) on mission can be quantified, and trade‐offs can be assessed and discussed. It gives students a chance to develop creative ideas for process improvement, and provides sufficient data for them to analyze the impact of their suggestions in a rigorous way.  相似文献   

Cheating among elementary school children: A machine learning approach     

Li Zhao  Yi Zheng  Junbang Zhao  Guoqiang Li  Brian J. Compton  Rui Zhang  Fang Fang  Gail D. Heyman  Kang Lee 《Child development》2023,94(4):922-940

Academic cheating is common, but little is known about its early emergence. It was examined among Chinese second to sixth graders (N = 2094; 53% boys, collected between 2018 and 2019) using a machine learning approach. Overall, 25.74% reported having cheated, which was predicted by the best machine learning algorithm (Random Forest) at a mean accuracy of 81.43%. Cheating was most strongly predicted by children's beliefs about the acceptability of cheating and the observed prevalence and frequency of peer cheating at school. These findings provide important insights about the early development of academic cheating, and how to promote academic integrity and limit cheating before it becomes entrenched. The present research demonstrates that machine learning can be effectively used to analyze developmental data.  相似文献

Changes in velocity profile according to blood viscosity in a microchannel     

Eunseop Yeom  Yang Jun Kang  Sang-Joon Lee 《Biomicrofluidics》2014,8(3)

Red blood cells (RBCs) are important to dictate hemorheological properties of blood. The shear-thinning effect of blood is mainly attributed to the characteristics of the RBCs. Variations in hemorheological properties alter flow resistance and wall shear stress in blood vessels. Therefore, detailed understanding of the relationship between the hemorheological and hemodynamic properties is of great importance. In this study, blood viscosity and blood flow were simultaneously measured in the same microfluidic device by monitoring the flow-switching phenomenon. To investigate blood flows according to hemorheological variations, the flow rate of blood samples (RBCs suspended in autologous plasma, dextran-treated plasma, and in phosphate buffered saline solution) was precisely controlled with a syringe pump. Velocity profiles of blood flows were measured by using a micro-particle image velocimetry technique. The shape of velocity profiles was quantified by using a curve-fitting equation. It is found that the shape of the velocity profiles is highly correlated with blood viscosity. To demonstrate the relationship under ex vivo conditions, biophysical properties and velocity profiles were measured in an extracorporeal rat bypass loop. Experimental results show that increased blood viscosity seems to induce blunt velocity profile with high velocity component at the wall of the microchannel. Simultaneous measurement of blood viscosity and velocity profile would be useful for understanding the effects of hemorheological features on the hemodynamic characteristics in capillary blood vessels.  相似文献
