Merging information for semiparametric density estimation

Summary.  The density ratio model specifies that the likelihood ratio of m −1 probability density functions with respect to the m th is of known parametric form without reference to any parametric model. We study the semiparametric inference problem that is related to the density ratio model by appealing to the methodology of empirical likelihood. The combined data from all the samples leads to more efficient kernel density estimators for the unknown distributions. We adopt variants of well-established techniques to choose the smoothing parameter for the density estimators proposed.     

福柯的自我建构理论及其教育意义

在当前对福柯理论所进行的探讨中,我们对福柯的诸如权力/知识、话语等理论给予了很多的关注,却很少关注福柯的自我建构理论及其所具有的意义.因此,本文立足于福柯的自我建构理论,通过对自我建构所运用的技术,来指出自我建构理论的实质内涵,以及其深层次下权力/知识、话语的作用,以此来认识自我建构的理论所具有的教育内涵,它对教育所产生的影响,最后对这种理论进行简要的评价.     

编辑主体性简论

编辑活动在中国已有上千年的历史,几乎与文化相伴而生,但又比文化更多几分主观观照。编辑是文明的阶梯,引导人们从蒙昧走向文明,其鲜明的方向性就在于编辑具有主体性。从中国文化发展的历程说明编辑主体性的重要性,阐述了编辑主体性的内涵,最后从中国现代化建设的现实需要出发,指出广大编辑工作者应充分发挥主体性,肩负起对时代的伟大责任。

Weakly implementable social choice rules

Previous investigations have shown that a social choice function which is partially implementable must be characterized by pervasive veto power. This paper investigates how much additional latitude in the design of social choice functions, and how much relief from this vetoers result, can be achieved by examining multi-valued social choice rules and relaxing the requirement of partial implementability to a requirement that we call weak partial implementability. We find that the power structures which characterize partially implementable social choice functions, including the veto properties, also characterize weakly partially implementable social choice rules. The conclusion is that invoking multi-valuedness and implementation of appealing social choice rules in strong Nash equilibria. Our results apparently exhaust the possibilities for implementation in strong Nash equilibrium. If any implementation possibility results are to be achieved, they can apparently come only by weakening the equilibrium requirement.     

Detection and correction of artificial shifts in climate series

Summary.  Many long instrumental climate records are available and might provide useful information in climate research. These series are usually affected by artificial shifts, due to changes in the conditions of measurement and various kinds of spurious data. A comparison with surrounding weather-stations by means of a suitable two-factor model allows us to check the reliability of the series. An adapted penalized log-likelihood procedure is used to detect an unknown number of breaks and outliers. An example concerning temperature series from France confirms that a systematic comparison of the series together is valuable and allows us to correct the data even when no reliable series can be taken as a reference.     

试论新约的死亡观

新约圣经对于死亡有其独特的信念与看法。概括说来 ,新约对死亡的看法包含着几个方面的含义 :灵性的死、旧我的死及身体的死。本文主要探讨了后两个方面的意义 ,认为正是这两个方面构成了新约死亡观的主要特征。首先 ,人可以活着经历自己 (旧我 )的死 ;如果从生存论层面来解释其末世论的意义的话 ,那么这种自我认同的转换正表明了旧我之死的深刻含义。其次 ,身体的死如果意味着人在此世之存在的结束的话 ,新约并没有将其看作是人之生命及其身体的结束。死亡乃意味着是个人生命或身体存在形态的转折点     

大学生自我概念与学业成就关系研究

自我概念是国内外心理学研究的一个中心问题。自我概念水平的高低与心理健康水平的高低成正比。健康的自我概念会对大学生心理、行为产生正面影响。自我概念与大学生的学业成就有着直接关系.应培养学生积极健康的自我概念。     

论刘勰文学批评的“文本”精神

刘勰的文学批评有别于先秦两汉时期的“以德为本”的文学批评。贯穿刘勰文学批评始终的是“以文为本”的精神,“文”是刘勰文学批评理论的核心,也是刘勰文学批评方法论依据。刘勰文学批评中的“文本”精神是我国文学批评走向自觉的重要标志。
