高职院校学生厌学归因及对策思考

学生的学习态度直接影响着学校的学风的形成、教学质量的提高和学生综合素质的提升。而在当前高职院校大学生普遍存在着厌学现象。文章针对这一现象提出大学生厌学的危害,再通过对在校生进行分层抽样问卷调查取得相应数据,运用归因理论对所收集的数据进行外在——稳定、外在——不稳定、内在——稳定、内在——不稳定等四种归因类型的原因分析,最终针对不同的归因类型提出不同的解决对策,以对高职院校学生的学风形成起到促进作用。     

论高校贫困大学生经济援助中的正义观

对贫困生的教育援助是一个关乎社会正义、和谐的问题。要健全和、完善我国高校贫困,大学生资助体系,实现教育公平,就必须将正义观贯穿经济援助的始终,通过调节相应的社会制度,从个人、高校、国家三个层面体现对贫困大学生经济援助的正义。     

大学评价的改进与完善——2009年中国大学及学科专业排行榜出炉

2009年中国大学及学科专业评价的做法有三个新的变化,一是在中国重点大学综合竞争力评价指标体系中,首次引入大学网络影响力指标替代社会声誉指标,占学校声誉指标的50%.结果发现绝大多数重点大学的网络影响力有待提高,各大学需要加大网站建设力度,制定相关政策促进科研成果的数字化、网络化,以便使更多的人能够通过网络获得相关的信息和知识.二是首次明确提出"中国一流大学"的概念、标准和排名结果;三是根据集中与离散分布规律,在学科专业评价结果的表示方面,首次引入星级表示方法.这样改革的效果是使评价方法与评价结果更趋于科学、合理,也更加符合时代发展的需要.

Finite particle method for kinematically indeterminate bar assemblies

This study presents a structural analysis algorithm called the finite particle method （FPM） for kinematically indeterminate bar assemblies. Different from the traditional analysis method, FPM is based on the combination of the vector mechanics and numerical calculations. It models the analyzed domain composed of finite particles. Newton＇s second law is adopted to describe the motions of all particles. A convected material flame and explicit time integration for the solution procedure is also adopted in this method. By using the FPM, there is no need to solve any nonlinear equations, to calculate the stiffness matrix or equilibrium matrix, which is very helpful in the analysis of kinematically indeterminate structures. The basic formulations for the space bar are derived, following its solution procedures for bar assemblies. Three numerical examples are analyzed using the FPM. Results obtained from both the straight pretension cable and the suspension cable assembly show that the FPM can produce a more accurate analysis result. The motion simulation of the four-bar space assembly demonstrates the capability of this method in the analysis ofkinematically indeterminate structures.     

中国城市广场空间设计的问题及对策

分析了当前中国城市广场空间设计的现状,认为中国城市广场的设计趋于同化,失去了城市的个性．同时,中国城市的广场空间出现了过于平面化、绿化面积过小、休闲设施不足、使用时间受限、广场景观统一化等问题．可以通过深度塑造广场立体空间、合理配置绿色植物、完善广场的休闲设施、强化广场空间景观个性的方法缓解以上矛盾．中国城市广场空间的发展潜力巨大,经过精心的规划设计,必将形成一个富有特色的城市景观体系。     

3D wind-induced response analysis of a cable-membrane structure

Wind loading is a dominant factor for design of a cable-membrane structure. Three orthogonal turbulent components, including the longitudinal, lateral and vertical wind velocities, should be taken into account for the wind loads. In this study, a stochastic 3D coupling wind field model is derived by the spectral representation theory. The coherence functions of the three orthogonal turbulent components are considered in this model. Then the model is applied to generate the three correlated wind turbulent components. After that, formulae are proposed to transform the velocities into wind loads, and to introduce the modified wind pressure force. Finally, a wind-induced time-history response analysis is conducted for a 3D cable-membrane structure. Analytical results indicate that responses induced by the proposed wind load model are 10%-25% larger than those by the con- ventional uncorrelated model, and that the responses are not quite influenced by the modified wind pressure force. Therefore, we concluded that, in the time-history response analysis, the coherences of the three orthogonal turbulent components are necessary for a 3D cable-membrane structure, but the modified wind pressure force can be ignored.
