专升本课程设置存在的问题与策略

发展专升本教育既是经济发展的需要,也是适应我国教育发展趋势、完善教育体系的需要。文章从专升本教学现状出发,并围绕"专升本课程设置"这一中心问题展开,探寻提高专升本教学质量的理论依据和实践途径。     

民办高校收费问题与对策

民办高校收费存在项目繁多、审核机构缺失、营销风气浓厚、资金使用模糊、服务滞后等问题。非规范性收费的主要危害在于：改变学校性质、阻碍学生顺利完成学业、损害学校形象、妨碍学校发展。解决非规范性收费问题的主要对策是：加强对非规范性收费危害的认识、合理确定收费标准、成立收费审核机构、规范收费管理、建立公示制度、加强监督检查工作等。     

论中子质量的组成

中子质量是由质子和电子以及它们之间的电场质量相加而成。并且,质量有正负之分,电子质量取负。中子的两种半径对应两种不同状态下的取值,用它们都可计算出中子质量,跟实验值一致。此外,还解出电子半径。     

罪名拟定的原则

罪名拟定必须坚持概括原则、文本原则、协调原则、准确原则。概括原则是指罪名应当简约、精炼。文本原则是指拟定罪名应当尽量使用罪状中的表述词汇。协调原则要求罪名之间应当协调一致,相似、相近罪名应当呈现出规律性。准确原则是指罪名应当反映罪名的本质特征,不能出现罪名的外延大于或者小于罪状的情形,更不能产生歧义。新通过的《刑法修正案(八)》涉及的争议罪名,运用如上四个原则拟定,会得出恰当结论。     

Fuel Burning Rate Model for Stratified Charge Engine

A zero-dimensional single-zone double-curve model is presented to predict fuel burning rate in stratified charge engines, and it is integrated with GT-Power to predict the overall performance of the stratified charge engines. The model consists of two exponential functions for calculating the fuel burning rate in different charge zones. The model factors are determined by a non-linear curve fitting technique, based on the experimental data obtained from 30 cases in middle and low loads. The results show good agreement between the measured and calculated cylinder pressures, and the deviation between calculated and measured cylinder pressures is less than 5%. The zero-dimensional single-zone double-curve model is successful in the combustion modeling for stratified charge engines.     

The history curriculum and its personal connection to students from minority ethnic backgrounds

Whereas history is seen by some as crucial in developing a sense of identity and fostering social cohesion, it is however, often based around narrowly nationalistic views of the past, and yet little is known about how students relate to the past they are taught. Thus, this paper focuses on the history curriculum and the ways in which students aged 12–14, from different ethnic backgrounds, relate to it. Moreover, the small-scale study which enabled this paper, focused, in particular, on whether students enjoyed and valued history and whether they felt any sense of personal connection to the topics studied. Drawing on survey data collected from 102 students and focus group discussions with 42 students, from two high schools, the findings indicate that although many students enjoy history, they fail to fully understand its value. Additionally most students, especially those from minority ethnic backgrounds, feel a lack of personal connection to the past, as they do not see themselves in the history they are taught.     

高职院校市场营销实务课堂教学与开放性作业的衔接研究--市场营销实务课程教学改革研究与实践

课堂教学和课后作业是教与学之中两个最为重要的节点。课堂教学的封闭性使得学生在课堂上消化知识、提高能力的时间和空间十分有限,如果学生课后没有及时巩固、锻炼,那么教师的课堂效能就不会理想,课堂教学的实际作用得不到体现。尝试封闭的课堂教学与开放性作业的衔接,是解决教学效果提升的最好方法。     

高功率Ni/MH电池用AB5型负极储氢合金的研究

研究和开发具有优异高倍率特性的储氢电极合金是发展高功率型Ni/MH电池的技术关键,具有重大的理论意义和商业价值。基于合金热力学和动力学行为的讨论,研究了AB5型储氢电极合金的微结构对其倍率放电性能的影响。结果表明,由于非化学计量(B/A >5 )和高催化活性第二相的引入,B侧添加硼或钼可以显著提高合金的高倍率放电容量和低温放电容量。进一步结合A侧稀土成分优化,发展出一类具有优异倍率性能的MmNi3.55Co0.75Mn0.4Al0.3Bx(Mm为混合稀土)合金。该系列合金有望应用于高功率Ni/MH电池和低温( - 35 oC)Ni/MH电池。     

儒家"经世"与王安石的"致用"

儒家的"经世"基于"知我者其天乎"的强烈信念,"致用"则是一种人文主义的使命感的体现.但是在封建的官僚制度运行中,"经世致用"实际上的运作与实践经历了极为不幸的命运.本文以王安石为例,剖析其与"经世"思想的因果关系和内在逻辑,试图对儒家经世思想发展的一个有代表意义的时段作一个浅显研究.
