公用企业的管制改革--重塑政府对公用企业的管制结构及管制职能

传统的公用企业管制机制是以所谓的“公用企业合法垄断理论”为依据的。我国的公用企业管制机制也是建立在这种理论基础之上的。这种机制虽然在计划经济条件下有其存在之合理性,但伴随市场经济体制的确立与推进,其理论上与实践上弊害逐渐显明。因此,对公用企业进行管制改革已势在必行,改革的途径是在借鉴西方国家公用企业管制改革经验的基础上,重塑我国公用企业的管制结构及管制职能。

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.     

A four spiral slots microstrip patch antenna for radiotelemetry capsules based on FDTD

Antenna is very crucial to radiotelemetry capsules which can measure the physiological parameters of the gastroin- testinal (GI) tract. The objective of this paper is to design a novel spiral slots microstrip patch antenna for the radiotelemetry capsules communicating with external recorder at 915 MHz located in ISM (Industry, Science, and Medical) bands. The microstrip patch antenna is designed and evaluated using the finite-difference time-domain (FDTD) method. Return loss characteristics and the effect of the human body on resonant frequency are analyzed, and the performances of radiation patterns at different positions of the human alimentary tract are also estimated. Finally, specific absorption rate (SAR) computations are performed, and the peak 1-g and 10-g SAR values are calculated. According to the peak SAR values, the maximum delivered power for the designed antenna was found so that the SAR values of the antenna satisfy the ANSI (American National Standards Institute) limitations.     

“科尔曼报告”述评——兼论对我国解决“上学难、上学贵”问题的启示

“科尔曼报告”是在二战后随着教育平等、教育民主化思潮的出现以及美国民权法案对教育机会均等现状调查的要求而产生的。报告对美国教育机会均等的现状和影响因素进行了科学的分析,认为校际间差距对不同种族的学生有不同的影响,造成儿童学习水平低的原因,主要不是学校的物质条件,而是学校内的社会因素。“科尔曼报告”深刻地影响了教育机会均等的理论研究与政策实践,对分析和探讨当前我国“上学难、上学贵”问题具有重要的借鉴意义。

Development of a plastic injection molding training system using Petri nets and virtual reality

INTRODUCTIONAt present, plastic as a substitute for metals in products is the most important mainstay in industrial raw materials. Furthermore, plastic injection molding is one of the most common and versatile methods for mass production of complex plastic parts with excel-lent dimensional tolerance. Since the technology of injection molding has been widely applied in manu-facturing, training on injection molding is of great importance. The traditional approach is to consult some technica…
