是褒扬“十六大”还是包装“生产力价值论”——再与胡义成先生商榷

我党提出要深入研究和探讨马克思的价值理论,是强调谱写新的理论篇章,是强调要用发展着的马克思主义指导当前的改革开放;十六大报告强调尊重劳动、知识、人才和创造,旨在调动一切积极因素,绝不是对劳动创造价值这一根本观点的否定;社会财富的源泉不等于就是价值的源泉,在价值源泉问题上劳动具有排他性,但在价值形成和价值分配问题上则不然;马克思《资本论》的学术价值以及它对全世界工人阶级解放事业的伟大作用,不容贬低和诋毁;地球上所有的财富和一切商品的价值,从古至今只能靠劳动来创造,非劳动主体创造使用价值和非一般人类劳动成为价值源泉的说教,纯属天方夜谭。     

基于物理元胞自动机的岩石破坏模拟

为了分析岩石材料的非均质性对其破坏演化的影响,根据元胞自动机理论,从能量的角度建立了一种能够从细观层次上对岩石破坏演化进行模拟的物理元胞自动机模型(Mh-PCA模型),模型引用的Weibull随机分布函数对材料的非均质性进行描述.运用该模型,对m分别为1,5,10,15四种不同均质度材料的破坏模式及其破坏过程中的声发射现象进行了模拟分析.结果表明:材料的非均质性对其破坏有重要的影响,均质度越高,破坏过程中的分支裂纹越少,声发射也越集中.物理元胞自动机理论为岩石的破坏研究提供了一种新的研究思路.     

栅格式燃烧器冷风配气特性数值模拟

建立了热风炉栅格燃烧器内空、煤气流动混合过程的三维物理、数学模型,对燃烧器内流场特性和组分浓度均匀性进行了数值模拟。计算结果揭示了燃烧器内空、煤气流场结构及混合过程;得到了燃烧器空气和煤气通道的阻力系数、速度均匀度以及组分浓度均匀度;同时分析了冷风配气均匀度的影响因素,为热风炉燃烧特性的研究奠定了基础。     

完善证券市场,提高资源配置的效率

资源配置是证券市场最基本的功能，应该从证券市场能否最大限度地动员资金并进行有效分配的角度去衡量证券市场的效率。市场失灵和我国证券市场所处的非常时期等主客观因素。造成了我国证堂市场发育不完善，效率低下。为提高我国证券市场资源配置的效率，证券市场需要监管和规范化。     

试析我国居民收入分配存在的问题、原因及对策

本试图对经济改革20余年来我国居民收入分配格局的变化，特别是近年来收入差距不断扩大问题进行初步研究。由于收入分配问题涉及面广，本只集中考察收入分配变化的一些重要方面。考虑到在我国经济转轨过程同现代经济发展过程并行这一特点，本从经济改革、体制调整等角度分析了我国居民收入差距变化的一般原因。章最后，本着公平与效率兼顾原则，就如何提高居民收入分配平等化程度提出某些有针对性的建议。     

湖南兰科兰属植物的研究

湖南兰属植物有7种、2变种和众多的栽培品种。其中3种为中国特有种,它们是蕙兰(Cymbidium faberi)、寒兰(C.kanran)和多花兰(C.floribundum);3种为湖南新记录种,即蕙兰、墨兰(C.sinense)和兔耳兰(C.lancifolium)。本文对湖南兰属植物的分类,地理分布和区系特点等进行了研究。     

合理的利益分配制度与和谐社会的构建

当前,随着社会利益关系的重新调整与组合,各种利益之间的分化和矛盾日趋激烈,利益过度分化影响着社会的和谐稳定．对和谐社会的构建提出严峻挑战。为此,在改革发展进程中应积极建立健全系统的社会利益协调机制,完善分配制度,实现社会的稳定,推动社会主义和谐社会的构建。     

论个人所得税调控功能的完善和发展

个人所得税的基本功能表现为增加财政收入和调节收入分配，随着个人收入差距的逐步拉大，它的征收状况对增加财政收入、满足政府进行宏观调控的财力需要，已经有相当重要的影响力，同时它的调节职能也受到了更多的关注。     

The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.     

中国高校女教师队伍发展的现状分析

This paper examines the changing status of women faculty through an analysis of statistics on China’s universities from 1994 to 2004. This paper first presents the trend of a drastic increase in women faculty members in recent years. Further details on the academic ranks of women faculty, their age and highest degrees obtained are also presented. A comparison of female representation in faculty ranks is made between China and a few selected countries. Lastly, this paper attempts to account for the low percentage of female professors in higher education. Recommendations for the professional development for women faculty are made in the end.
