大中专在校学生考试分数的正态化线性转换

本文分析了考试记分方法中传统的绝对百分体制的缺陷，给出了一种正态化转换分数的算法，较适合于在校大中专学生学习水平的横向评价。     

基本剩余价值初探

剩余价值在其历史发展中相继地采取了绝对剩余价值、相对剩余价值和基本剩余价值的直接表现形式。基本剩余价值是在绝对剩余价值和相对剩余价值尚未产生或产而复失的历史场合中必须生产的 ,也是在实行绝对剩余价值生产和相对剩余价值生产的历史场合中 ,被它们凸现出来并使它们赖以产生的具有原先既定性 ,或扩张基础性和增生本体性的剩余价值形式。基本剩余价值生产与资本主义生产相始终 ,是资本主义生产目的的基本实现。它和绝对剩余价值、相对剩余价值在质和量及其历史形态上的差异 ,使剩余价值成为一个比较经济范畴     

全球视野内的中国贫困问题研究

中国贫困问题的研究应顺应贫困研究国际趋势其中国贫困走向进行相应调整,即顺应贫困演变趋势,从研究绝对贫困向研究相对贫困转化;改变政策取向,从关注集体贫困向关注个体贫困转化;拓宽研究范围,从研究物质贫困向人文贫困转化;转变研究方法,从一般经济学分析拓宽到制度经济学分析。在对策设计上,应从加强反贫困制度建设、实行瞄准贫困人口的扶贫政策、缩小收入差距和关注人文贫困等方面加以考虑。     

没有场的空间是不存在的——广义相对论的空间概念

本文简述了空间概念的发展历程。经典力学和SR把空间看作虚无,而GR则认为空间是 物质的。从而指出了空间概念是人类思维的自由创造。     

On Schelling＇ s View of Art and Nature

艺术与自然的关系,一直是西方古典美学中一个争论不休的问题。从古希腊到近代德国的美学家们都曾加以思考,并提出了不同的看法。作为德国古典美学代表人物之一的谢林,对艺术与自然的看法与他对艺术本质的理解是一致的。他反驳了两种流行的观点,并提出自己的独特理念。谢林的看法,与康德和黑格尔有所不同。谢林的论述,对我们今天认识艺术与自然、人与自然之关系仍有借鉴意义。     

A Weighted Least Squares Approach to Levene's Test of Homogeneity of Variance

In 1960 Levene suggested a potentially robust test of homogeneity of variance based on an ordinary least squares analysis of variance of the absolute values of mean-based residuals. Levene's test has since been shown to have inflated levels of significance when based on the F-distribution, and tests a hypothesis other than homogeneity of variance when treatments are unequally replicated, but the incorrect formulation is now standard output in several statistical packages. This paper develops a weighted least squares analysis of variance of the absolute values of both mean-based and median-based residuals. It shows how to adjust the residuals so that tests using the F -statistic focus on homogeneity of variance for both balanced and unbalanced designs. It shows how to modify the F -statistics currently produced by statistical packages so that the distribution of the resultant test statistic is closer to an F-distribution than is currently the case. The weighted least squares approach also produces component mean squares that are unbiased irrespective of which variable is used in Levene's test. To complete this aspect of the investigation the paper derives exact second-order moments of the component sums of squares used in the calculation of the mean-based test statistic. It shows that, for large samples, both ordinary and weighted least squares test statistics are equivalent; however they are over-dispersed compared to an F variable.     

Outlier detection and robust variable selection via the penalized weighted LAD-LASSO method

This paper studies the outlier detection and robust variable selection problem in the linear regression model. The penalized weighted least absolute deviation (PWLAD) regression estimation method and the adaptive least absolute shrinkage and selection operator (LASSO) are combined to simultaneously achieve outlier detection, and robust variable selection. An iterative algorithm is proposed to solve the proposed optimization problem. Monte Carlo studies are evaluated the finite-sample performance of the proposed methods. The results indicate that the finite sample performance of the proposed methods performs better than that of the existing methods when there are leverage points or outliers in the response variable or explanatory variables. Finally, we apply the proposed methodology to analyze two real datasets.     

理解黑格尔绝对精神的几个维度

路德的宗教改革与法国启蒙精神产生了德国古典哲学,黑格尔是德国古典哲学的集大成者。黑格尔哲学完成了一个封闭的圆圈,不管黑格尔哲学怎样复杂,其基本上还是一种精神人格的类型学。黑格尔认为是绝对精神成就了顶峰,把顶峰说成为一种精神人格。将几位德国精神的代表与黑格尔作比较是理解黑格尔绝对精神的关键。     

语言的“不可译性”简析

语言的“不可译性”既有“文化不可译性”与“语言不可译性”之分,也有“相对不可译性”与“绝对不可译性”之别,应该具体分析和区别对待。研究语言的“不可译性”,有利于进一步了解不同语言和文化的异同,也有助于进一步探讨翻译理论,尤其是翻译标准。     

审美现代性视野中的米兰·昆德拉

与卡林内斯库的审美现代性理论不同,米兰·昆德拉提出的“欧洲小说”观念,是以审美现代性对抗“资产阶级的现代性”的源头所在。米兰·昆德拉在小说理论和创作实践中展现出了对资产阶级的启蒙现代性的批判,和对审美现代性立场的坚执中产生的反省,阐述了他独特的“欧洲小说观”与审美现代性起源新说。他站在小说家的立场上,以审美现代性的态度,审视和评判现代生活,深入地考察了现代人生存中的一系列现象：媚俗,舞者,轻与重,快与慢,记忆与遗忘,革命、鸟托邦与抒情姿态,等等,犀利地揭示出其中的现代性悖谬。
