Optimal Block Designs With Interference Effects From Neighboring Units Under a Non Additive Model

Here, the optimality of block design with interference effect from neighboring unit under a general non additive model is investigated, which allows for the presence of interactions among the treatments applied in the adjacent plots. A non additive model with interference × direct effects of treatments is considered as these effects contribute significantly to the response. A class of complete block designs balanced for interference effects from left neighboring unit is shown to be universally optimal for the estimation of direct and interference effects of treatments and two such series of designs have been constructed. Furthermore, considering direct treatment × block non additivity with interference effects, the optimality is studied and the optimal designs are obtained.     

Designs with Repeated Measurements on Any Number of Units over Varying Periods

In the usual repeated measurements designs (RMDs), the subjects are all observed for the same number of periods and the optimum RMDs require specified numbers of subjects, usually depending on the number of treatments to be used. In practice, it is sometimes not feasible to meet these requirements. To overcome this problem, alternative designs are suggested where any number of available subjects may be used and they may be observed for different periods. These designs are based on suitable serially balanced sequences which are shown to be optimal. Moreover, besides the usual direct and residual effects, the model considered has an extra term due to the interaction effect between them. The recommended designs are universally optimal in a very general class.     

张学良对东北抗日义勇军的方针1

九一八事变后,张学良在公开执行“不抵抗”政策的同时,对东北义勇军的抗战,一直坚持暗中支持援助的方针,对义勇军的兴起起到了关键性作用。但这一方针的实行,不具政府行为的支持,力度极为有限,才导致了义勇军的最后失败。既要公开执行“不抵抗”的政策,又暗中实行支持义勇军的方针,使张学良在九一八事变后一直处于两难境地的尴尬状态中。总体上看,张学良对东北抗日义勇军的支持行为没能改变其“不抵抗”政策的本质。     

索绪尔的语言单位观

索绪尔对语言单位非常重视,尽管他没有明确指出有哪些语言单位,但通观其语言学理论,我们认为他总结了语言单位的性质,包括同一性、意义结合、系统性以及现成性。在此基础上,索绪尔智慧地区分了词汇单位和语法单位,前者包括词和熟语,后者包括词形构造模式、词组构造模式和句子构造模式,但后者意义更重大。     

Optimal block designs with non additive mixed effects interference

This paper deals with optimality aspects of block designs balanced for interference effects from neighboring units on both sides under a general non additive model along with random block effects. Here, a class of complete, circular block designs strongly balanced for interference effects has been shown to be universally optimal for the estimation of direct effects and interference effects (left and right) of treatments under a non additive mixed effects model.

论政府职能的第二次转变——政事分开、管办分离改革的理论与实践

对政府职能转变的历史趋势及理论分析表明,我国转变政府职能的改革要实现第二次转变,其突破口是政事分开、管办分离。北京、上海、无锡、苏州等地以各种模式推行的改革探索,证明此项改革可能达到推进行政管理体制改革、深化事业单位改革、优化公共服务等目的。进一步推进此项改革,要探索建立无“婆婆”、有监管、“小政府”、“大市场”、打破垄断、放开准入、统筹规划、整体协调的社会事业新体制。     

一种新的双目标DEA模型

在经济系统的分析研究中,由于资源的有限性,我们总想以最少的投入获得最多的产出。本文给出了决策单元输入总量最小且输出总量最大时的一种双准则DEA模型,并用线性加权和法对其进行了求解,该模型能使所有决策单元同时达到相对效率最优。     

Can Donor PIUs Support Country Systems?

The OECD's Paris Declaration (2005) discouraged donor project implementation units (PIUs) which are not integrated into government. But little is known about the behaviour and effects of PIUs integrated into government. Are they efficient? Do they support country systems? This article responds to these questions using research comparing two streams of implementation of schools investments in Malaysia's Eighth Plan 2001–2005, one via government alone and the other via a World Bank PIU integrated into government. It emphasises the conflicts which can exist within country systems, and how these affect the choices which a donor faces in seeking efficient implementation of a project while supporting country systems.     

中国航空法延误责任限额与华沙体系的协调

华沙公约体系特别规定了旅客运输延误责任限额,中国的航空法体系没有将其与旅客人身伤亡赔偿限额进行区分。中国航空法体系对赔偿责任限额的计算单位与具体国家货币换算所规定的折算方法与华沙公约体系不符,涉及折算货币的规定亦不适当。文章在分析中国航空法体系与国际华沙公约体系的有关规定基础上,对延误的赔偿责任限额制度的有关具体问题予以明晰,以期为中国修改航空法有关规定,实现与华沙公约体系无缝对接提供建议。
