高素质新型政工人才培养的举措

高素质新型政工人才的培养是个系统工程，它包括树立新的教育观念，构建多样化的人才培养模式，提高教员队伍的整体素质，建立和完善合力育人机制，营造良好的育人环境。     

新课标下的数学课堂教学

数学课堂教学不仅是传授知识、形成技能、发展智力的过程,而更是教师引导学生经历数学化的过程,是促进学生全面、主动发展的过程,是承认学生差异、张扬学生个性的过程,是学生之间自主交流、合作探索的过程,是落实德育教育的过程,是理论知识和生活问题密切联系的过程,是数学课程资源的开发、利用、拓展的过程,是数学教师专业化发展的过程.     

月亮意象原始及嬗变

我们对月亮神话的分析中看到原始的信息是先民们对生殖的崇拜，赋予月亮阴性特征；随后月亮本身具有的视觉审美特征和女性的月水守信共同衍生了月亮比德入诗，具有爱情忠贞、君子守信的意义；唐以来月亮表达了一种人情结——富有悲剧意识之思，从而月亮学意象内涵便凝固了下来。这三次转变都未脱离月亮的视觉特征，但它们本身又是承传发展的。     

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.     

Multi-objective aerodynamic optimization design of high-speed train head shape

To improve the aerodynamic performance of high-speed trains (HSTs) running in the open air, a multi-objective aerodynamic optimization design method for the head shape of a HST is proposed in this paper. A parametric model of the HST was established and seven design variables of the head shape were extracted. Sample points and their exact values of optimization objectives were obtained by an optimal Latin hypercube sampling (opt. LHS) plan and computational fluid dynamic (CFD) simulations, respectively. A Kriging surrogate model was constructed based on the sample points and their optimization objectives. Taking the total aerodynamic drag force and the aerodynamic lift force of the tail coach as the optimization objectives, the multi-objective aerodynamic optimization design was performed based on a non-dominated sorting genetic algorithm-II (NSGA-II) and the Kriging model. After optimization, a series of Pareto-optimal head shapes were obtained. An optimal head shape was selected from the Pareto-optimal head shapes, and the aerodynamic performance of the HST with the optimal head shape was compared with that of the original train in conditions with and without crosswinds. Compared with the original train, the total aerodynamic drag force is reduced by 2.61% and the lift force of the tail coach is reduced by 9.90% in conditions without crosswind. Moreover, the optimal train benefits from lower fluctuations in aerodynamic loads in crosswind conditions.     

略论加强我国教育行政监督

“教育行政监督是指有关机关对教育行政主体在教育行政过程中是否依法行政进行监督的活动.”在当前我国高等教育快速发展的新形势下,借鉴国外教育行政监督的经验,切实加强我国教育行政监督,对于防止权力滥用,保障高等教育事业健康发展,具有十分重要的意义.     

入世与我国企业人力资源的开发管理

加入世贸会给我国的人才队伍带来冲击，也带来机遇；我们应采取各种措施，积极应对，在全球化的竞争中立于不败之地。     

“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。
