双轴平动椭圆振动筛设计中的有关问题

本文在首次提出双轴惯性振动筛“力心”概念的基础上,对双轴惯性椭圆振动筛设计中的有关分析进行了讨论,列举了若干算例,编制了相应的计算机软件,可供振动筛研制设计时应用。根据本文所述方法,已经研制成功了具有平动椭圆运动轨迹的PTZS振动筛。     

悲剧文化与生命的双重辩护——青年尼采生存论文化观探析

青年尼采的文化观是生存论性质的。陷于“绝望的真理”中的生命需要辩护,需要文化给予它何以生存的正当理由。希腊日神文化和酒神文化分别赋予了个体生活和永恒生活以正当性,而悲剧文化则同时给予尘世生活和形而上生活双重的辩护。悲剧文化的现代意义在于,在“宗教退潮”之后,它担当了宗教的救世功能。     

Application of numerical interval analysis to obtain self-validating results for multivariate probabilities in a massively parallel environment

Conventional computations use real numbers as input and produce real numbers as results without any indication of the accuracy. Interval analysis, instead, uses interval elements throughout the computation and produces intervals as output with the guarantee that the true results are contained in them. One major use for interval analysis in statistics is to get results of high-dimensional multivariate probabilities. With the efforts to decrease the length of the intervals that contain the theoretically true answers, we can obtain results to any arbitrary accuracy, which is demonstrated by multivariate normal and multivariate t integrations. This is an advantage over the approximation methods that are currently in use. Since interval analysis is more computationally intensive than traditional computing, a MasPar parallel computer is used in this research to improve performance.     

《庄子》同心圆寓言初探

围绕同一寓意而组织起来的若干篇寓言,即同心圆寓言。在对同心圆寓言作了界定的同时,对《庄子》同心圆寓言也进行了分析,认为《庄子》同心圆寓言可分为平列式、嵌入式和公转式三种类型。《庄子》同心圆寓言,既可以形象地表达思想,也能鞭辟入里地进行论辩,还有利于保存寓言珍品。     

当前中国土地市场发展状况及趋势分析

当前中国的土地市场发展很快,市场化程度逐步加深,土地政策作为宏观经济的调控手段的作用日益加强,国家对土地监控力度加大。但原有体制的惯性、现存土地市场的二元性及政府参与土地经营等方面的因素,导致市场发育不是很完备,目前土地市场存在许多急需改革的方面。对此要改变农村与城市分割的二元性土地制度以及相关的国家对城市土地一级市场的垄断现象,改革土地市场的“价格双轨制”,完善管理土地的制度和法律框架,进一步规范政府的行为。     

关于不报、谎报安全事故罪的几点思考

认定不报、谎报安全事故罪,应注意理解"不报或谎报"、"安全事故情况"、"贻误事故抢救"等客观方面的构成要素;本罪与其他安全事故犯罪发生关联适用时,应数罪并罚;本罪与滥用职权罪或玩忽职守罪发生关联适用时,应以本罪论处;本罪属于过失情节犯,而过失情节犯是存在一定的内在冲突的,将本罪规定为过失情节犯属于立法缺陷,因此有必要将本罪中的"情节严重"修改为"造成严重后果",即通过抛弃情节犯、规定过失犯的危害结果要件来完善本罪立法.     

三峡库区农村贫困恶性循环的二元经济结构理论分析

目前中国城乡经济结构的二元化特征非常明显，消除城乡二元差异已成为当前经济工作的重点。针对三峡库区的具体情况．从农村贫困恶性循环入手，揭示库区城乡经济二元化的原因．并提出相应对策。     

沟通民间的叙事策略——论乡土叙述者文学史意义

乡土人物取代知识分子成为叙述者是1990年代后乡土叙事上的一个显著特征，它是90年代知识分子身份反思在文学文体上的应证。乡土叙述者的叙述语言打开了一扇通往乡土世界的大门，是对知识分子启蒙视角中知识分子眼光和思维方式的挑战和颠覆，而这其中《秦腔》中引生这个叙述人的出现尤其具有文学史意义，它基本上实现了叙述意义从民族国家寓言向乡土生活本身的转变。     

Adaptive Strategies,Gender Ideology,and Work‐Family Balance Among Dutch Dual Earners

Using questionnaire data on 149 Dutch dual‐earner couples with young children participating in the European Famwork study, we examine how adaptive strategies and gender ideology relate to parents’ perceived success in balancing work and family. Path analysis indicates that some adaptive strategies may harm individuals’ work‐family balance, particularly when they are made in the domain where the time budget is limited. In the need to succeed in multiple roles, however, endorsement of traits traditionally linked with the opposite gender, that is masculine traits for women and feminine traits for men, seems beneficial. We speculate that two underlying mechanisms — social pressure and time constraints — jointly operate in determining perceived success in balancing work and family.     

Explaining the causes of poverty in the West Indies: A cross-cultural comparison

Research into attitudes towards the poor and lay explanations for poverty have heen primarily concerned with the structure and determinants of these attitudes and explanations. Whereas a number of variables — education, religion, ethnic group — have been shown to relate to explanations for poverty, there have only been a few cross-cultural studies. This study set out to compare the explanations adolescents gave for poverty in two West Indian islands — the relatively wealthy island of Barbados and the relatively poor island of Dominica. The overall economic development/prosperity of the two islands, and the extent and visibility of economic inequality between the two islands appeared to account for the numerous national differences. These results are discussed in terms of the social, political and historical differences between the two islands.
