False Though Partly True – An Experiment in Logic

We explore in an experimental spirit the prospects for extending classical propositional logic with a new operator P intended to be interpreted when prefixed to a formula as saying that formula in question is at least partly true. The paradigm case of something which is, in the sense envisaged, false though still partly true is a conjunction one of whose conjuncts is false while the other is true. Ideally, we should like such a logic to extend classical logic – or any fragment thereof under consideration – conservatively, to be closed under uniform substitution (of arbitrary formulas for sentence letters or propositional variables), and to allow the substitutivity of provably equivalent formulas salva provabilitate. To varying degrees, we experience some difficulties only with this last (congruentiality) desideratum in the two four-valued logics we end up giving our most extended consideration to.     

On relative universality and Q-universality

Adams and Dziobiak proved that any finite-to-finite universal quasivariety must be Q-universal, and then asked whether a somewhat weaker hypothesis could lead to the same conclusion. We show that their original hypothesis cannot be weakened to its naturally extreme form.To Professor Ale Pultr on his 65th birthdayThe authors gratefully acknowledge the support of the NSERC of Canada, of the project LN00A056 of the Czech Ministry of Education, and also of the Grant Agency of Czech Republic under the grant 201/02/0148.Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by M.

Distributive Justice and Clinical Trials in the Third World

One of the arguments against conducting human subject trials inthe Third World adopts a distributive justice principle found ina commentary of the CIOM'S Eighth Guideline for internationalresearch on human subjects. Critics argue that non-participantmembers of the community in which the trials are conducted areexploited because sponsoring agencies do not ensure that theproducts developed have been made reasonably available to theseindividuals.I argue that the distributive principle's wording is too vagueand ambiguous to be used to criticize any trial. Furthermore,the mere fact that an experiment does not fulfill this particulardistributive justice principle does not entail that it isunethical.     

绩效、能力、职位对组织分配公平观的影响

旨在探索基于组织分配公平的认知评价和决策行为的影响因素,为此提出了不公平阈限的概念,即在追求公平和谋求自我利益的动机权衡中,个体为了追求公平而愿意放弃的最高限度的个人利益。采用最后通牒博弈和独裁者博弈的二阶段实验范式,样本量为60。结果发现,工作绩效、工作能力均对个体的不公平阈限有显著的影响;对于公平判断和基于公平的回应行为,工作绩效起着首要作用,工作能力的影响次之,再次是对方的提议数额的影响。第一阶段对方提议的分配方案对被试越有利,则第二阶段被试的回应行为越有利于对方。排除能力差别的作用之后,职位差别并未引起不公平阈限的显著差异。根据研究结果,总结出分配公平的三项原则：绩效原则、能力原则和互惠原则     

When does priming justice promote forgiveness? On the importance of distributive and procedural justice for self and others

Two studies show that thinking about justice can both enhance and impede forgiveness, depending on whether thoughts about distributive and procedural justice for self and others are activated. In Study 1 (n = 197), participants expressed more forgiveness towards a prior transgressor when primed to think about justice for self or procedural justice for others, and less forgiveness when primed to think about distributive justice for others. Study 2 (n = 231) used an alternate priming method and replicated these effects by inducing an interpersonal transgression and measuring forgiveness intentions, emotions and behavior. Study 2 also showed that priming justice influences forgiveness especially when the perceived severity of an interpersonal offense is high. The current research shows that activating justice cognitions can enhance or impinge on forgiveness in predictable ways. We discuss contributions to emerging justice theory, potential implications, and future directions.     

Multiple reference points in satisfaction and fairness assessment

Most studies of reference point effects have used a single referent, such as a price, a salary, or a target. There is considerable evidence that the judged fairness of, or satisfaction with, an outcome is significantly influenced by discrepancies from such single referents. In many settings, however, more than one reference point may be available, so the subject may be confronted simultaneously with some referents above, some at, and some below the focal outcome. Little is known about the simultaneous impact of such multiple reference points. We examine here the effects of two referents on ratings of salary satisfaction and fairness. Subjects were presented with a series of scenarios that described a salary offer made to a hypothetical MBA graduate and provided information about the salary offers made to either one or two other similar graduates. For each scenario, subjects judged how fair the focal graduate would feel the offer to be, and how satisfied he or she would be with it. Satisfaction ratings displayed asymmetric effects of comparisons: the pain associated with receiving a salary lower than another MBA is greater than the pleasure associated with a salary higher than the other student by the same amount. Fairness ratings showed a different pattern of asymmetric effects of discrepancies from the reference salaries: the focal graduate's salary was judged somewhat less fair when others received lower offers, and much less fair when others received higher offers. The asymmetric effects occurred for both reference points, suggesting that the focal salary was compared separately to each of the referents rather than to a single reference point formed by prior integration of the referents.

Duality and Canonical Extensions of Bounded Distributive Lattices with Operators,and Applications to the Semantics of Non-Classical Logics II

The main goal of this paper is to explain the link between the algebraic models and the Kripke-style models for certain classes of propositional non-classical logics. We consider logics that are sound and complete with respect to varieties of distributive lattices with certain classes of well-behaved operators for which a Priestley-style duality holds, and present a way of constructing topological and non-topological Kripke-style models for these types of logics. Moreover, we show that, under certain additional assumptions on the variety of the algerabic models of the given logics, soundness and completeness with respect to these classes of Kripke-style models follows by using entirely algebraical arguments from the soundness and completeness of the logic with respect to its algebraic models.     

Motives and Likelihood of Bribery: An Experimental Study of Managers in Taiwan

Many studies of bribery acknowledge the important role of bribe-givers, but their true motives remain unclear. We propose that the likelihood of bribery depends on the willingness of an organization to affiliate with local parties or to be successful in a host country, or to have power over local parties. We further argue that different opportunities, either pervasive or arbitrary, facilitate different types of motives that affect the likelihood of bribery. In addition, we investigate the effect of perceived fairness on the likelihood of bribery. We employ a 3 (motives: affiliation vs. achievement vs. power)?×?2 (opportunities: pervasiveness vs. arbitrariness)?×?2 (perceived fairness: high vs. low) factorial design in experimental settings among Executive MBA students in southern Taiwan. Our findings indicate that, when companies perceive a higher level of distributive fairness, high-achieving organizations are more likely to offer a bribe when the condition is pervasive. When they have a powerful motive, arbitrariness engenders a higher likelihood of bribery. When they perceive less distributive fairness, there are no significant differences between motive and opportunity.     

儿童的分配公平性:心理理论的作用

心理理论是影响儿童分配公平性的重要因素之一。"多重动机"的理论假设认为心理理论能够帮助儿童在不同的动机中权衡利弊,找到满足自我利益和他人需求之间的平衡;其中,感知需求、推断意图、理解情绪是影响独裁者博弈、最后通牒博弈、第三方惩罚中分配公平性的主要成分。未来研究需为此提供更多实证依据,探讨不同类型的公平分配与心理理论各组成成分的关系,以及可否通过训练心理理论能力促进儿童公平概念的发展。     

Rising powers' responsibility for reducing global distributive injustice

Rising powers like India and Brazil have recently been gaining considerable economic and political power. This has led to the emergence of a nascent multipolarity in global affairs. Theorists of global distributive justice, however, continue to focus almost exclusively on the responsibility of the established powers for combating global poverty and neglect whether there is a similar responsibility of rising powers. That focus neglects that great shifts have occurred in the distribution of the economically severely poor over the past three decades. According to recent work by Andy Sumner, 74% of those who live in extreme economic poverty resided in middle-income countries in 2008. This paper explores this lacuna and shows that there are several grounds for attributing a similar responsibility to rising powers. These grounds are familiar from discussions of the established powers' responsibility for global distributive injustice in the writings of John Rawls, Peter Singer and Thomas Pogge. They are the capacity to stop, the contribution to and the benefits from global distributive injustices.
