A generating algorithm for linear trend-free and nearly linear trend-free block designs

The theory and properties of trend-free (TF) and nearly trend-free (NTF) block designs are wel1 developed. Applications have been hampered because a methodology for design construction has not been available.

This article begins with a short review of concepts and properties of TF and NTF block designs. The major contribution is provision of an algorithm for the construction of linear and nearly linear TF block designs. The algorithm is incorporated in a computer program in FORTRAN 77 provided in an appendix for the IBM PC or compatible microcomputer, a program adaptable also to other computers. Three sets of block designs generated by the program are given as examples.

A numerical example of analysis of a linear trend-free balanced incomplete block design is provided.     

CDM在河北省秸秆发电项目中的应用研究

河北省是一个农业大省,每年秸秆产量十分可观.通过分析河北省晋州24MW秸秆发电项目,估算出河北省秸秆发电项目经核证的减排量(CERs)的收益;并分析了秸秆发电发展所面临的一系列障碍.若将此类项目开发成为CDM项目,将有助于克服这些障碍.     

Censored Kullback-Leibler Information and Goodness-of-Fit Test with Type II Censored Data

The Kulback-Leibler information has been considered for establishing goodness-of-fit test statistics, which have been shown to perform very well (Arizono & Ohta, 1989; Ebrahimi et al., 1992, etc). In this paper, we propose censored Kullback-Leibler information to generalize the discussion of the Kullback-Leibler information to the censored case. Then we establish a goodness-of-fit test statistic based on the censored Kullback-Leibler information with the type 2 censored data, and compare the test statistics with some existing test statistics for the exponential and normal distributions.

论中国传统死亡观对第三代诗人的潜在影响

儒家的“重生轻死”、道家的“厌生乐死”、佛家的“生死轮回”观深深影响着第三代诗人的思想和创作。他们以对死亡的直面、认同，传达着强烈的对生的关注和思考；以对死亡的想象性体验，表达着对生命本质的观照和认识。“死亡”成了第三代诗人自我认知与个性传达的言说载体。     

论陈抟易学思想的影响

陈抟所开启的宋代象数易学一方面以《周易》的卦爻象数为基础,另一方面又超出卦爻象数之外,创新性地融合易老之说,积极探索自然万物的化生奥秘。陈抟易道相通、太极是一的宇宙本体论,融合了道家本体论和儒家太极说,并与道教内丹学紧密结合。同时,这种宇宙生成模式对邵雍、刘牧、周敦颐等宋儒以思维性启迪和深刻影响。

Entropy Principles in Decision Making Under Risk

This paper considers decision problems where: (1) The exact probability distribution over the states of nature is not precisely known, but certain prior information is available about the possibilities of these outcomes; (2) A prior distribution over the states of nature is known, but new constraint information about the probabilities becomes available. The maximum entropy principle asserts that the probability distribution with maximum entropy, satisfying the prior knowledge, should be used in the decision problem. The minimum cross-entropy principle says that the posterior distribution is the one which minimizes cross-entropy, subject to the new constraint information. The entropy principles have not gone uncriticized, and this literature, together with that justifying the principles, is surveyed. Both principles are illustrated in a number of situations where the distribution is either discrete or continuous. The discrete distribution case with prior interval estimates based on expert opinions is considered in detail.     

人民群众的根本利益：社会主义核心价值体系价值生成的动因

社会主义核心价值体系是社会主义意识形态的本质体现，它的价值生成必然有着“中国特色”的内在动因。依据利益与价值的关系、利益与价值观的关系两层逻辑推衍，并在中国特色社会主义实践中可以得到证明的是：利益是人民群众价值活动的逻辑起点；人民群众的根本利益不仅彰显了社会主义核心价值体系的本旨，而且是社会主义核心价值体系价值生成的“中国特色”的动因。     

A case-based distance method for screening in multiple-criteria decision aid

Screening is a process of multiple-criteria decision aid (MCDA) in which a large set of alternatives is reduced to a smaller set that most likely contains the best choice. We propose screening using a distance model calibrated on the basis of the decision-maker's own judgement. Viewing MCDA as preference aggregation based on consequence data, we define consequence and preference expressions (values and weights) and describe how they are aggregated. Then we define screening and explain some of its properties. Using an appropriate definition of distance, our case-based distance method screens a set of alternatives using criterion weights and a distance threshold obtained by quadratic optimization using the decision-maker's selection of alternatives from a test set. This case-based method can elicit the decision maker's preferences more expeditiously and accurately than direct inquiry. An application in water supply planning is used to demonstrate the procedure.
