A multicriteria assignment problem

Our objective in this paper is to propose a procedure for solving a multicriteria assignment problem. Given qualitative and quantitative data, the proposed procedure makes assignments taking into consideration the multicriteria aspect of the problem. As an illustrative example, we consider the assignment of referees to the football matches in an Italian championship. Copyright © 2003 John Wiley & Sons, Ltd.     

Metaphysical Infinitism and the Regress of Being

This article offers a limited defense of metaphysical “infinitism,” the view that there are, or might be, infinite chains of ontological dependence. According to a widespread presupposition, there must be an ultimate ground of being—most likely, a plurality of fundamental atoms. Contrary to this view, this article shows that metaphysical infinitism is internally coherent. In particular, a parallel with the debate concerning infinitism about epistemic justification is suggested, and an “emergence model” of being is put forward. According to the emergence model, the being of any given entity gradually arises out of an infinite series of progressively less dependent entities—it is not wholly transmitted, as it were, from a basic, ungrounded level to all the dependent ones in a step‐by‐step fashion. Some objections are considered and rebutted.     

Moral priorities under risk

Many moral theories are committed to the idea that some kinds of moral considerations should be respected, whatever the cost to ‘lesser’ types of considerations. A person’s life, for instance, should not be sacrificed for the trivial pleasures of others, no matter how many would benefit. However, according to the decision-theoretic critique of lexical priority theories, accepting lexical priorities inevitably leads us to make unacceptable decisions in risky situations. It seems that to operate in a risky world, we must reject lexical priorities altogether. This paper argues that lexical priority theories can, in fact, offer satisfactory guidance in risky situations. It does so by equipping lexical priority theories with overlooked resources from decision theory.     

An Alternate Method of Deriving Priorities and Related Inferences for Group Decision Making in Analytic Hierarchy Process

Some work has been carried out in the past on statistically deriving priorities in Analytic Hierarchy Process (AHP). In AHP, the aggregated worths of the alternatives, when compared with respect to several criteria, are estimated in a hierarchical comparisons model introduced by Saaty. In this setup, statistical models are used for Saaty's method of scaling in paired comparisons experiments in any level of the hierarchy. At the end, the final priority weights of the alternatives and related inferences are developed with appropriate statistical methods. Existing statistical methods in the literature assume independence of the entries of the paired comparison matrix. However, these entries are highly dependent among themselves. In this article, we propose a statistical method that allows for the dependence among the entries of the pairwise comparisons matrix. The proposed method is then illustrated with a numerical example.

几何线索直接性和显著性对儿童菱形空间再定向的影响

以25名幼儿园中班儿童为研究对象,采用在一个边或角有颜色标记的菱形平面的四个角或边位置中藏物找物的任务,来探究几何线索的直接性和显著性如何影响5岁儿童对几何及非几何线索的利用。研究发现:几何线索优先性并不稳定;几何线索的直接性影响了几何线索的使用;在几何线索直接的条件下,几何线索的显著性影响了几何线索的使用;几何线索直接性及显著性均不影响儿童对颜色线索的使用。     

Causation in a New Old Key

I argue (1) that it is not philosophically significant whether causation is linguistically represented by a predicate or by a sentence connective; (2) that there is no philosophically significant distinction between event- and states-of-affairs-causation; (3) that there is indeed a philosophically significant distinction between agent- and event-causation, and that event-causation must be regarded as an analog of agent-causation. Developing this point, I argue that event-causation's being in the image of agent-causation requires, mainly, (a) that the cause is temporally prior to the effect, (b) that the cause necessitates (is sufficient with necessity) for the effect. Causal necessity is explained as a derivative of nomological necessity, and finally, via a definition of the causal sentence connective, the logic of event-causation is shown to be a part of temporal modal logic.     

全面建设小康社会与思想道德教育的重点

在全面建设小康社会的历史实践中 ,思想道德教育对培育社会主义先进文化和建立社会主义道德体系 ,具有举足轻重的作用。当前 ,思想道德教育的重点环节应放在以下三个方面 :加强对广大农村居民的思想道德教育 ;围绕依法治国和以德治国相结合的治国方略有效开展法治、德治教育 ;在方法论上实现由以义务为起点的思想道德教育转变为以权利为起点的思想道德教育 ,由单纯的思想道德教育转变为以利益赏罚为载体的思想道德教育。     

公平与效率：优先性与制度安排的博弈分析

公平与效率问题是人类社会生活中备受关注的问题之一 ,在社会主义市场经济发展过程中 ,人们的讨论更是激烈。有人说公平优先于效率 ,有人说效率优先于公平。笔者认为公平与效率是分属不同分配领域的优先原则 ,效率相对于生产资料分配领域而言 ,公平则相对于生活资料分配领域而言。笔者运用博弈分析法说明 :公平与效率可以通过科学的制度设计可以达到最佳的结合。
