道德的经济学——亲缘选择与广义效用理论

早期功利主义者认为效用不仅包括人们获得的物质利益,还包括精神上的追求和道德上的满足感。然而经济学数学化和公理化的趋势使经济学家更愿意把效用解释为物质利益上的满足,这极大地限制了经济学的解释力度。广义效用理论是在现代经济学的框架下对效用含义的扩展。通过对当前广义效用理论的回顾,结合生物学中的亲缘选择理论,提出了一个广义效用模型,并对模型的结果进行了分析。     

河北高等教育对区域经济发展的效应分析

随着经济发展区域化和高等教育地区化,高等教育与区域经济通过良性互动,谋求共同发展已成为必然。一个区域高等教育的实力与水平,很大程度上反应着该区域的经济实力和发展水平。河北高等教育对其区域经济发展的促进效用十分突出,但亟需改进完善的方面也不容轻视。     

Deconvolution methods for non-parametric inference in two-level mixed models

Summary.  We develop a general non-parametric approach to the analysis of clustered data via random effects. Assuming only that the link function is known, the regression functions and the distributions of both cluster means and observation errors are treated non-parametrically. Our argument proceeds by viewing the observation error at the cluster mean level as though it were a measurement error in an errors-in-variables problem, and using a deconvolution argument to access the distribution of the cluster mean. A Fourier deconvolution approach could be used if the distribution of the error-in-variables were known. In practice it is unknown, of course, but it can be estimated from repeated measurements, and in this way deconvolution can be achieved in an approximate sense. This argument might be interpreted as implying that large numbers of replicates are necessary for each cluster mean distribution, but that is not so; we avoid this requirement by incorporating statistical smoothing over values of nearby explanatory variables. Empirical rules are developed for the choice of smoothing parameter. Numerical simulations, and an application to real data, demonstrate small sample performance for this package of methodology. We also develop theory establishing statistical consistency.     

Testing monotonic equilibrium residual entropy of N-State Random Evolution

In this study, we propose an information measure of uncertainty associated with the random equilibrium residual lifetime of a system driven by N-State Random Evolution. A U-statistic test driven by a moment inequality is proposed for testing the hypothesis that the uncertainty of equilibrium remaining life of a system remains unchanged (when system is in the steady state) against the alternative situation when system’s equilibrium residual life has increasing uncertainty over time (i.e., the life distribution has Increasing Equilibrium Residual Entropy property). Some numerical results such as tabulated critical values and empirical power of the proposed test statistic are presented as well.     

论新时期思想政治工作的创新

思想政治工作是我党的优良传统和政治优势,是一切工作取得胜利的可靠保证。面对新世纪、新形势,创新是思想政治工作的时代要求。新时期要真正使思想政治工作的创新积极、主动、稳妥、有效地取得实质性进展,应重点抓好三个方面的创新:观念上的创新、内容上的创新与充实、方法上的创新。     

平实的深刻:论朱自清的《新诗杂话》

《新诗杂话》是朱自清先生研究中国现代新诗的一部著作。朱先生在这部诗学著作中,坚守诗歌文本的分析,坚持对诗歌意义进进缜密详实的“解读”,并认为这是新诗研究的基础。论及范围宽泛,富于创见性,是这部著作的显著特点。以“解诗”为出发点,《新诗杂话》探讨了诗与感觉、诗与哲理、诗与幽默、抗战与诗、诗与建国、诗的形式、歌谣与译诗、新诗的进步性、新诗的发展趋势等诸多关系,平实而深刻,精确而简洁,“将深化为浅”是《新诗杂话》最富于生机与活力的语言叙述原则。     

影响私人轿车拥有的因素分析

轿车进入家庭不是单一因素的结果。通过对影响轿车拥有和使用的因素,即效用、收入、城市结构、城市交通、城市道路设施和政策导向等六个方面的分析,指出应从多层面来研究中国汽车工业作为支柱产业的支撑条件,使汽车工业产出与运行需求均衡发展。     

如何理解价值的两个定义

价值的两个定义——政治经济学定义(支持劳动价值论)和哲学定义(支持效用价值论),各有自己的适用条件和范围,可以并存。正本溯源,价值的政治经济学定义才是价值的定义;在经济学范围,价值的政治经济学定义才是价值的定义;面对今天价值概念泛化的现实,价值的哲学定义才是价值的定义。     

Confidence intervals for treatment effect from restricted maximum likelihood

An explicit form of confidence intervals for the treatment effect in random effects meta-analysis model obtained from Harville–Jeske–Kenward–Roger approach is given. These restricted likelihood based intervals are compared to alternative procedures commonly used in collaborative studies when the number of participants is small and study-specific variances are heterogeneous. Monte Carlo simulation experiments show that the former intervals have quite conservative coverage probabilities and favor the latter intervals.
