新时期高校教师素质的探讨

在人类进入 2 1世纪的时候 ,教师的地位和作用已为越来越多的人们所认识 ,教师要适应经济、科技和社会协调发展的需要 ,接受时代的挑战 ,才能培养出社会主义建设者和接班人。高校教师应该具备崇高的敬业精神、广博的文化知识、娴熟的职业技能、高超的教学艺术、现代的教学手段、强烈的竞争意识、健康的个性特征、强烈的创新精神、完美的人格力量和一定的监控能力等十个方面素质 ,才能完成时代赋予的历史任务     

劳动力转移的经济分析

劳动力转移是发展中国家在经济发展与转型中特有的现象,在我国伴随农村剩余劳动力向城市转移形成了不同的利益集团。现从各利益集团之间的矛盾入手,提出不同利益集团之间均衡状态是和谐社会的必要条件。分析农村剩余劳动力向城市转移过程中各个利益集团的利益、目标、手段、能力等特征后,运用利益集团理论建立模型,分析他们之间相互作用的动因、机制并讨论其均衡结果。     

Non-parametric Regression with Dependent Censored Data

Abstract.  Let ( X _i , Y _i ) ( i = 1 ,…, n ) be n replications of a random vector ( X , Y  ), where Y is supposed to be subject to random right censoring. The data ( X _i , Y _i ) are assumed to come from a stationary α -mixing process. We consider the problem of estimating the function m ( x ) = E ( φ ( Y ) |  X = x ), for some known transformation φ . This problem is approached in the following way: first, we introduce a transformed variable     , that is not subject to censoring and satisfies the relation     , and then we estimate m ( x ) by applying local linear regression techniques. As a by-product, we obtain a general result on the uniform rate of convergence of kernel type estimators of functionals of an unknown distribution function, under strong mixing assumptions.     

局部Haar条件下的Chebyshev同时逼近(英文)

本文在局部 Haar 条件下,讨论了紧空间上非线性 Dunham 型 Chebyshev 同时逼近,得到了同时逼近为局部最佳的充分必要条件;给出了与非线性同时逼近问题等价的相关线性同时逼近问题;证明了极小集的存在性,在这个极小集上的局部最佳逼近为局部最佳的;获得了区间上非线性同时逼近的交错定理;证明了非线性同时逼近的α阶(α≥1)的强唯一常数等于其相关线性同时逼近的α阶强唯一常数。     

Children's perceptions of others' understanding of moral transgressions: who should know better and why

The present study examined children's perceptions of other children's ability to make moral judgements. Preschool, kindergarten, first- and second-grade children rated the permissibility of moral transgressions for a same-age peer, a younger child and an older child. Children also were asked why the transgressions were wrong. Preschool and kindergarten children rated transgressions equally wrong for a same-age peer, a younger and an older child, whereas first and second graders rated transgressions for a same-age peer and an older child as more wrong than for a younger child. Preschoolers stated they did not know why the transgressions were wrong for a younger child, while kindergarten children reasoned that a younger child did not know the rules. First and second graders reasoned that a same-age peer and an older child should know ‘better’, but a younger child would not know ‘better’. Results suggest that children's perceptions of others' moral knowledge is related to children's ability to coordinate domains of social knowledge when making judgements of others' moral transgressions.

本文从长期的二元结构所造成的人力资源的知识能力巨大差距出发 ,根据知识经济时代的要求 ,把人力资源的知识能力划分为编码知识与非编码知识 ;并建议成立国家职业技术教育部及其系统机构 ,侧重提高传统农业社区人力的非编码知识能力 ,共同发展现代知识经济。     

综合业务CATV网络

本文提出了一种宽带分布式网络设计,该网络能在CATV电缆上同时进行数据、实时数字话音及模拟电视通信。本系统能支持大量用户间的通信。由于采用了宽带技术和总线网令牌与CSMA/CD的混合协议,从而解决了局域网所面临的距离和时延问题。本文最后对所提出网络的话音性能作了评估,所得结果与相关试验报导数据相符。     

Demography of disaster: Population estimates after hurricane Andrew

Hurricane Andrew blasted through the southern tip of Florida in August 1992, damaging or destroying tens of thousands of homes and forcing hundreds of thousands of persons to move at least temporarily to different places of residence. The hurricane not only disrupted the lives of many Floridians, but destroyed the statistical basis for producing local population estimates in South Florida as well. These estimates are used for many types of decision-making, from the distribution of state revenue-sharing dollars to choosing sites for fast-food restaurants. This article describes the estimation problems created by the hurricane and how those problems were resolved through the use of existing data sources and the collection of new types of data. It closes with a discussion of several conceptual, methodological and procedural issues that will have to be faced in virtually any attempt to estimate the demographic consequences of natural disasters.An earlier version of this paper was presented at the 1994 annual meeting of the Population Association of America, Miami, Florida, USA.     

我们需要什么样的工程哲学

工程在人类活动中的地位变得日益重要的同时,也对社会、政治和环境提出了日益严峻的挑战.思考这些问题,我们应该立足于作为一门有别于传统科学技术哲学的工程哲学.古希腊以来,科学与工程一直被认为代表了西方文化两种不同的传统.但在哲学发生历史主义转向后,两种不同的合理性走向融合.在科学的社会研究变得时髦的今天,我们对工程这种物质性活动进行哲学研究的进路就再也不能采用传统哲学那种单一的规范化方法,而应该将其视为一种特殊的文化活动,从多维外部视点来理解.工程知识和工程实践的特性使得工程哲学应该超越传统的规范化方法,而去描述作为一种社会活动的工程实践,并在容纳各个外部视点后综合每个视点所形成的视图,为工程活动"拼凑一种更好的描述".     

知识经济与高校学风建设

知识经济对现代社会的方方面面将产生巨大的影响,高等学校和高校教育工作者,要结合实际、抓住时机、改变观念,加强教育和引导,促使大学生转变思维、提高思想认识,积极树立良好的学风,建立“终生学习”的观念,培养创新意识。
