马来西亚政府非常重视私立教育,其私立教育发展速度及发达程度非常惊人。马来西亚私立教育中的 "特许课程"和3+0、2+1、1+2等"双联课程"的制定与实施,也是颇具特色的,事实证明其成果是十分显著的。这种 教育的开放性、办学模式的灵活性及管理手段的适应性,都是马来西亚私立教育能在近十几年中得以迅速发展的重 要原因,是应该得到充分肯定的。如何解决发展中国家私立大学发展进程中出现的问题,使私立高等教育得以健康 发展,可以从马来西亚私立大学的发展及特点中得到一些有益的启示。  相似文献

With the proliferation of the Internet and World Wide Web applications, people are increasingly interacting with government to citizen (G2C) eGovernment systems. It is therefore important to measure the success of G2C eGovernment systems from the citizen's perspective. While general information systems (IS) success models have received much attention from researchers, few studies have been conducted to assess the success of eGovernment systems. The extent to which traditional IS success models can be extended to investigating eGovernment systems success remains unclear. This study provides the first empirical test of an adaptation of DeLone and McLean's IS success model in the context of G2C eGovernment. The model consists of six dimensions: information quality, system quality, service quality, use, user satisfaction, and perceived net benefit. Structural equation modeling techniques are applied to data collected by questionnaire from 119 users of G2C eGovernment systems in Taiwan. Except for the link from system quality to use, the hypothesized relationships between the six success variables are significantly or marginally supported by the data. The findings provide several important implications for eGovernment research and practice. This paper concludes by discussing limitations of the study which should be addressed in future research.  相似文献

A novel microstirring strategy is applied to accelerate the digestion rate of the substrate Nα-benzoyl-L-arginine-4-nitroanilide (L-BAPA) catalyzed by sol-gel encapsulated trypsin. We use an ac nonlinear electrokinetic vortex flow to stir the solution in a microfluidic reaction chamber to reduce the diffusion length between the immobilized enzyme and substrate in the solution. High-intensity nonlinear electroosmotic microvortices, with angular speeds in excess of 1 cm∕s, are generated around a small (∼1.2 mm) conductive ion exchange granule when ac electric fields (133 V∕cm) are applied across a miniature chamber smaller than 10 μl. Coupling between these microvortices and the on-and-off electrophoretic motion of the granule in low frequency (0.1 Hz) ac fields produces chaotic stream lines to stir substrate molecules sufficiently. We demonstrate that, within a 5-min digestion period, the catalytic reaction rate of immobilized trypsin increases almost 30-fold with adequate reproducibility (15%) due to sufficient stirring action through the introduction of the nonlinear electrokinetic vortices. In contrast, low-frequency ac electroosmotic flow without the granule, provides limited stirring action and increases the reaction rate approximately ninefold with barely acceptable reproducibility (30%). Dye molecules are used to characterize the increases in solute diffusivity in the reaction reservoir in which sol-gel particles are placed, with and without the presence of granule, and compared with the static case. The solute diffusivity enhancement data show respective increases of ∼30 and ∼8 times, with and without the presence of granule. These numbers are consistent with the ratios of the enhanced reaction rate.  相似文献

Inter-firm social links are always helpful to establish mutual trust for further cooperation, and inter-firm knowledge exchange stresses the relative importance in a technological field. This study first examines the differences and relationships among the networks that are constructed by different exchanged resources, and further explores how a firm’s embedded local cluster resources and the brokerages’ roles in different inter-firm networks shape a firm’s leading position in the technical knowledge field. To construct inter-firm networks, we survey all members in the Taiwan Fastener Industry Association, collecting 87 valid samples for a 67% response rate. We use QAP (Quadratic Assignment Procedure) regressions to examine the relationships among networks, including social network (SN), information network (IN), and knowledge network (KN). We execute a negative binomial regression to investigate the importance of cluster resources and cross-regional brokering roles in SN and IN for gaining a higher position in technical KN. The results first show that the ties in SN and IN help establish cooperative partnerships in exchanging technical knowledge. Second, local cluster resources play a critical role in driving firms to gain a higher position in KN. Third, to have a leading role in KN, the brokerage roles in IN seem to be more important than the brokerages in SN. In particular, cross-regional brokerage roles (e.g., liaison) in IN strengthen their position in KN.  相似文献
