On the Standard and Rational Completeness of some Axiomatic Extensions of the Monoidal T-norm Logic

The monoidal t-norm based logic MTL is obtained from Hájek's Basic Fuzzy logic BL by dropping the divisibility condition for the strong (or monoidal) conjunction. Recently, Jenei and Montgana have shown MTL to be standard complete, i.e. complete with respect to the class of residuated lattices in the real unit interval [0,1] defined by left-continuous t-norms and their residua. Its corresponding algebraic semantics is given by pre-linear residuated lattices. In this paper we address the issue of standard and rational completeness (rational completeness meaning completeness with respect to a class of algebras in the rational unit interval [0,1]) of some important axiomatic extensions of MTL corresponding to well-known parallel extensions of BL. Moreover, we investigate varieties of MTL algebras whose linearly ordered countable algebras embed into algebras whose lattice reduct is the real and/or the rational interval [0,1]. These embedding properties are used to investigate finite strong standard and/or rational completeness of the corresponding logics.     

实验设计:一种非模式的方法

实验设计通常被当作一种种设计模式．这种方法可称之为实验设计的模式方法。但本文认为,这种常用的方法事实上存在着不少缺点。于此．本文尝试提出了一种新的实验设计方法——实验设计的变量方法。实验设计的变量方法的基本思想是．从实验研究的问题出发,根据实验中变量的性质或特点确定实验设计的具体内容。本文最后讨论了实验设计变量方法的优越性。

市场经济、道德权利与产权伦理

产权伦理是现代市场经济的一个根本性的精神基础,是建立有效的产权制度及其运行机制的重要条件;同时,它是人类道德体系的核心价值理念之一,是基于权利,义务与道德的内在逻辑构建起来的。产权伦理的研究具有重要的理论价值和现实意义,可以构成一门具有特殊的学科特质,研究方法和理论内容的伦理学学科。     

近十年国外罗夏测验攻击变量研究综述

用罗夏测验测量攻击有助于了解个体的攻击性冲动 ,也有助于外显攻击行为的预测和控制。近十年国外文献中有关研究者主要有Holt、Exner、Gacono和Meloy。综述结果表明 ,他们提出的大多数攻击变量都有明确的定义 ,其实证研究也获得了一些支持。但也可以看到 ,目前的研究依然存在不少问题 :(1 )变量的定义有重复、内容有交叉 ;(2 )变量的分类标准不唯一 ;(3 )某些变量的使用和操作欠方便。因而 ,这些变量的定义、分类和使用都还有待于进一步研究支持。     

Countertransference and the female triangular situation3

This paper represents an attempt toward reconciling contemporary changes in psychoanalytic understandings of female development, particularly in respect to separation issues, with their clinical applications to female patients. Psychoanalytic thinking typically has categorized separation conflicts as pre‐oedipal, but the authors suggest that these are an integral part of the triangular situation of the girl. The authors argue that an allegiance to erroneous theory and/or individual blind spots have led to the infantilization, pre‐oedipalization or cultural stereotyping of females, which constrains the effectiveness of their analyses. The authors present a selected review of the literature on gender‐based countertransference biases in both male and female analysts, with reference to female ‘oedipal’ material. Analytic case material of two women is presented which demonstrates how theoretical misperceptions and countertransferences to triangular separation conflicts can produce an impediment to progression in analysis.     

THE ETHICS OF LAND RESTITUTION

Many indigenous communities were dispossessed of their land during the period of colonial rule. This long process resulted in forced demographic removals and perennial poverty. Nowadays these communities, especially Third World groups, seek redress of this situation through legal processes of land restitution. This process is met by resistance from landowners in these countries, the colonial powers of old, as well as from big corporations that benefited from the dispossession. The investigation undertaken in this article addresses the ethics of land reform from a Christian ethical perspective. The policy of land restitution in South Africa is used as a case study, but the results of this research are also applicable to other parts of the world where land restitution is considered. The article first evaluates the biblical teachings of land and land reform and their implications for modern ethics. In the light of these issues, the article addresses the question of whether land ownership can be considered as a fundamental human right. The article also focuses on the legality of expropriation and dispossession of land for the purposes of restitution. Moreover, guidelines for fair and legal restitution within the context of Christian ethics and legal philosophical principles are proposed.     

Libertarianism vs. Marxism: Reflections on G. A. Cohen‘s Self-Ownership, Freedom and Equality

Self-Ownership, Freedom and Equality is G.A. Cohens attempt to rescue something of the socialist outlook on society from the challenge of libertarianism, which Cohen identifies with the work of Robert Nozick in his famous book, Anarchy, State, and Utopia. Sympathizing with the leading idea that a person must belong to himself, and thus be unavailable for forced redistribution of his efforts, Cohen is at pains to reconcile the two. This cannot be done – they are flatly contrary. Moreover, equality is a nonsense principle, calling for such things as equal distribution of natural resources. But resources, as goods, are not natural: all require work to utilize. The only thing exchanged on markets is services, and estimates of value received are relevantly made only by those party to the exchanges in question. Imposition from above on voluntary exchange can only be socially counterproductive.     

Concurrent second-order schedules of reinforcement

Responses on one key (the main key) of a two-key chamber produced food according to a second-order variable-interval schedule with fixed-interval schedule components. A response on a second key (the changeover key) alternated colors on the main key and provided a second independent second-order variable-interval schedule with fixed-interval components. The fixed-interval component on one variable-interval schedule was held constant at 8 sec, while the fixed interval on the other variable-interval schedule was varied from 0 to 32 sec. Under some conditions, a brief stimulus terminated each fixed interval and generated fixed-interval patterns; in other conditions, the brief stimulus was omitted. Relative response rate and relative time deviated substantially from scheduled relative reinforcement rate and, to a lesser extent, from obtained relative reinforcement rate under both brief-stimulus and no-stimulus conditions. Matching was observed with equal components on both schedules; with unequal components, increasingly greater proportions of time and responses than the matching relation would predict were spent on the variable-interval schedule containing the shorter component. Preference for the shorter fixed interval was typically more extreme under brief-stimulus than under no-stimulus schedules. The results limit the extension of the matching relation typically observed under simple concurrent variable-interval schedules to concurrent second-order variable-interval schedules.
