The anti-Specker property, a constructive version of sequential compactness, is used to prove constructively that a pointwise continuous, order-dense preference relation on a compact metric space is uniformly sequentially continuous. It is then shown that Ishihara's principle BD-ℕ implies that a uniformly sequentially continuous, order-dense preference relation on a separable metric space is uniformly continuous. Converses of these two theorems are also proved.

Various types of continuity for preference relations on a metric space are examined constructively. In particular, necessary and sufficient conditions are given for an order-dense, strongly extensional preference relation on a complete metric space to be continuous. It is also shown, in the spirit of constructive reverse mathematics, that the continuity of sequentially continuous, order-dense preference relations on complete, separable metric spaces is connected to Ishihara's principleBD-ℕ, and therefore is not provable within Bishop-style constructive mathematics (...) alone.

The basic theory of preference relations contains a trivial part reflected by axioms A1 and A2, which say that preference relations are preorders. The next step is to find other axims which carry the theory beyond the level of the trivial. This paper is to a great part a critical survey of such suggested axioms. The results are much in the negative — many proposed axioms imply too strange theorems to be acceptable as axioms in a (...) general theory of preference. This does not exclude, of course, that they may well be reasonable axioms for special calculi of preference. I believe that many axioms which are rejected here may be plausible if their range of application is restricted by conditions which are possible to formulate only in a language richer than that of the propositional calculus, e.g. in one containing modal operators or probabilistic concepts.

This article proposes a general strategy to overcome normative conflicts, namely, paradoxes represented in Standard Deontic Logic. This solution is based on preference relations between norms that circumvent situations of conflict. Pragmatic justifications of the proposed method are also given.

In order to account for non-traditional preference relations the present paper develops a new, richer framework for preference relations. This new framework provides characterizations of non-traditional preference relations, such as incommensurateness and instability, that may hold when neither preference nor indifference do. The new framework models relations with swaps, which are conceived of as transfers from one alternative state to another. The traditional framework analyses dyadic preference relations in terms of (...) a hypothetical choice between the two compared alternatives. The swap framework extends this approach by analysing dyadic preference relations in terms of two hypothetical choices: the choice between keeping the first of the compared alternatives or swapping it for the second; and the choice between keeping the second alternative or swapping it for the first.

According to Wlodek Rabinowicz's fitting-attitude analysis of comparative value, it is possible to analyse both standard and non-standard value relations in terms of the standard preference relations and two levels of normativity. In a recent article, however, Johan Gustafsson has argued that Rabinowicz's analysis violates a principle of value–preference symmetry, according to which for any value relation, there is a corresponding preference relation. Gustafsson has proposed an alternative analysis which respects this principle and which allegedly (...) accounts for the idea that originally motivated Rabinowicz's analysis, namely, that in some cases different preference relations between a pair of items are equally permissible. The goal of my article is to show that the arguments offered by Gustafsson in favour of his account do not succeed. In particular, I argue that Gustafsson faces a dilemma: either he abandons the principle of value–preference symmetry or he cannot make conceptual room for multiple permissible preferences. (shrink)

We investigate in intuitionistic first-order logic various principles of preference relations alternative to the standard ones based on the transitivity and completeness of weak preference. In particular, we suggest two ways in which completeness can be formulated while remaining faithful to the spirit of constructive reasoning, and we prove that the cotransitivity of the strict preference relation is a valid intuitionistic alternative to the transitivity of weak preference. Along the way, we also show that the (...) acyclicity axiom is not finitely axiomatizable in first-order logic. (shrink)

Preference relations are intensively studied in Economics, but they are also approached in AI, Knowledge Representation, and Conceptual Modelling, as they provide a key concept in a variety of domains of application. In this paper, we propose an ontological foundation of preference relations to formalise their essential aspects across domains. Firstly, we shall discuss what is the ontological status of the relata of a preference relation. Secondly, we investigate the place of preference relations (...) within a rich taxonomy of relations (e.g. we ask whether they are internal or external, essential or contingent, descriptive or nondescriptive relations). Finally, we provide an ontological modelling of preference relation as a module of a foundational (or upper) ontology (viz. OntoUML). The aim of this paper is to provide a sharable foundational theory of preference relation that foster interoperability across the heterogeneous domains of application of preference relations.

This paper studies the properties of eight semantic consequence relations defined from a Tarski-logic L and a preference relation ≺. They are equivalent to Shoham’s so-called preferential entailment for smooth model structures, but avoid certain problems of the latter in non-smooth configurations. Each of the logics can be characterized in terms of what we call multi-selection semantics. After discussing this type of semantics, we focus on some concrete proposals from the literature, checking a number of meta-theoretic properties and (...) elaborating on their intuitive motivation. As it turns out, many of their meta-properties only hold in case ≺ is transitive. To tackle this problem, we propose slight modifications of each of the systems, showing the resulting logics to behave better at the intuitive level and in metatheoretic terms, for arbitrary ≺.

Joshua Gert and Wlodek Rabinowicz have developed frameworks for value relations that are rich enough to allow for non-standard value relations such as parity. Yet their frameworks do not allow for any non-standard preference relations. In this paper, I shall defend a symmetry between values and preferences, namely, that for every value relation, there is a corresponding preference relation, and vice versa. I claim that if the arguments that there are non-standard value relations are (...) cogent, these arguments, mutatis mutandis, also show that there are non-standard preference relations. Hence frameworks of Gert and Rabinowicz's type are either inadequate since there are cogent arguments for both non-standard value and preference relations and these frameworks deny this, or they lack support since the arguments for non-standard value relations are unconvincing. Instead, I propose a simpler framework that allows for both non-standard value and preference relations. (shrink)

_ Source: _Page Count 30 Millions of children worldwide could benefit from adoption. One could argue that prospective parents have a pro tanto duty to adopt rather than create children. For the sake of argument, I assume there is such a duty and focus on a pressing objection to it. Prospective parents may prefer that their children are genetically related to them. I examine eight reasons prospective parents have for preferring genetic children: for parent-child physical resemblance, for family resemblance, for (...) psychological similarity, for the sake of love, to achieve a kind of immortality, for the genetic connection itself, to be a procreator, and to experience pregnancy. I argue that, with the possible exception of the pregnancy desire, these reasons fail to defeat a duty to adopt a child rather than create one, even assuming that we do have some leeway to favor our own interests.

In the first section of this paper I draw, on a purely conceptual level, a distinction between two kinds of reasons: content-related and attitude-related reasons. The established view is that, in the case of the attitude of believing something, there are no attitude-related reasons. I look at some arguments intended to establish this claim in the second section with an eye to whether these argument could be generalized to cover the case of preferences as well. In the third section I (...) argue against such generalizations and present a case in favour of accepting attitude-related reasons for preferences. In the fourth section I present an objection to which I react in the fifth section where I try to strengthen my case for attitude-related reasons for preferences. Finally, I discuss and reject criticisms raised by two opponents of the view defended here. (shrink)

(1) This paper uses the following binary relations: > (is preferred to); ⩽ (is not preferred to); < (is less preferred than); ~ (is indifferent to). (2) Savage used primitive ⩾, postulated to be connected and transitive onA (the set of acts), to define the others: [x ~ y ⇔ (x ⩽ y and y ⩽ x)]; [y < x ⇔ notx ⩽ y]; [x > y ⇔ y < x]. Independently of the axioms, this definition implies that ⩽ (...) and > are complementary relations onA: [x < y ⇔ notx > y]. (3) Pratt, Raiffa and Schlaifer used primitive ⩽, postulated to be transitive onL (the set of lotteries), to define the others with a different expression for <: [x < y ⇔ (x ⩽ y and noty ⩽ x)]. Thus, ⩽ and > are not necessarily complementary onL; since ⩽ is not postulated to be connected onL, but connected ⩽ is necessary and sufficient for such complementarity. Since the restriction of ⩽ to the subsetA ofL is connected, ⩽ and > are complementary onA. (4) Fishburn used primitive < onA to define the others with different expression for ~ and ⩽: [x ~ y ⇔ (notx < y and noty < x)]; [x ⩽ y ⇔ (x < y orx ~ y)]. His version of Savage's theory then assumed that < is asymmetric and negatively transitive onA. Thus, ⩽ and > are complementary, since asymmetric < is necessary and sufficient for such complementarity. (5) This analysis provides a new proof that the same list of elementary properties of binary relations onA applies to all three theories: ⩽ is connected, transitive, weakly connected, reflexive, and negatively transitive; while both < and > are asymmetric, negatively transitive, antisymmetric, irreflexive, and transitive; but only ~ is symmetric.

Biochar is a soil—improving substrate made from phytomass pyrolysis. In Southeast Asia, its application decreases due to the long-term growth of biochar cost and thus caused further prolongation of the payback period. In the Euro-American civilization the biochar application is already almost forgotten once it has been much earlier recognized that the crop yields can be increased much faster with higher doses of nutrients and other agrochemicals. The payback period can be expected in decades. Such a long-time investment into soil (...) fertility raises also many ethical questions. The final decision combines issues of social responsibility, risk and other financial indicators as well as personal preferences and more. The attitudes of Western and Central European decision makers in the agriculture business segment were analyzed on the basis of electronic questionnaire survey and a subsequent interview through their local unions. According to the data, most of them did not know about the possibilities of a more environmentally friendly approach to soil enhancement based on the addition of a fertilizer in the form of biochar. Among others, the collected data also shows that the decision makers from Western Europe have a much different ethical approach to the land and financial indicators than the Central Europeans.

The topological structures imposed on the collection of binary relations on a given set by the symmetric difference metric and the Hausdorff metric provide opportunities for learning about how collections of binary relations with various properties fit into the collection of all binary relations. For example, there is some agreement and some disagreement between conclusions drawn about the rarity of certain properties of binary relations using first the symmetric difference metric and then the Hausdorff metric.

Dalālat al-lafẓī al-waḍʿī, is divided into three parts: mutābaqat, taẓam-mun and iltizām. Although there is an agreement among the scholars regar-ding the nature of the mutābaqat, which shows the conformity of the word to its meaning, the indication of taẓammun and iltizām includes certain controversial issues. Among these, some issues related to iltizām, which plays a central role in method and rhetoric, were discussed. Al-Bābertī who wrote al-şurūḥ [commentaries] on the main works that greatly influenced the ones written after him (...) in these two sciences, expressed his opinion on the controversial issues; especially on the issues related to iltizām. These are about whether a mental necessity (al-luzūm al-dhihnī) condition is sought for the rationality and realization of the obligatory indication. In this context, at the beginning of the article, firstly, a general information about dalālat will be given, and in the first part, how the dalālat is handled in works of Bābertī will be explained. Then, in the second part, controversial issues related to dalālat will be discussed; views of Bābertī on these will be revealed after the discussions of scholars are included, especially within the framework of the nature of iltizām.

When is it appropriate to harm a single person to help multiple others? Psychologists have investigated this question through the study of hypothetical “trolley” dilemmas involving extreme physical harm life-or-death situations that contrast outcome-focussed, consequentialist moral reasoning with principle-focussed, deontological moral reasoning. The present studies investigate whether participants’ preference for consequentialism generalises across domains. We administered traditional physical harm dilemmas as well as a trolley-type dilemma involving monetary harm. Across four studies (N = 809), an internal meta-analysis demonstrated that (...) participants’ responses to the traditional dilemmas predicted their responses to the monetary dilemma. Additionally, previous research has uncovered that primary psychopathy predicts consequentialist responses on physical harm dilemmas. The current work uncovers that this association does not generalise to monetary harm dilemmas, suggesting that the association between primary psychopathy and consequentialist reasoning is not related to consequentialist reasoning per se, but to the idiosyncrasies of traditional harm-centric trolley dilemmas instead.

Most of us have two strong intuitions (or sets of intuitions) in relation to fairness in health care systems that are funded by public money, whether through taxation or compulsory insurance. The first intuition is that such a system has to treat patients (and other users) fairly, equitably, impartially, justly and without discrimination. The second intuition is that doctors, nurses and other health care professionals are allowed to, and may even in some cases be obligated to give preference to (...) the interests of their particular patients or clients over the interests of other patients or clients of the system. These two intuitions are in potential conflict. One of the most obvious ways in which to ensure impartiality in a health care system is to require impartiality of all actors in the system, i.e. to give health care professionals a duty to treat everyone impartially and to deny them the ‘right’ to give their patients preferential treatment. And one of the possible side-effects of allowing individual health care professionals to give preference to ‘their clients’ is to create inequality in health care. This paper explores the conflict and proposes that it can be right to give preference to ‘your’ patients in certain circumstances. (shrink)

According to Wlodek Rabinowicz's (2008) fitting-attitude analysis of value relations, two items are on a par if and only if it is both permissible to strictly prefer one to the other and permissible to have the opposite strict preference. Rabinowicz’s account is subject, however, to one important objection: if strict preferences involve betterness judgements, then his analysis contrasts with the intuitive understanding of parity. In this paper, I examine Rabinowicz’s three responses to this objection and argue that they (...) do not succeed. I then propose an alternative solution. I argue that the objection can be avoided if we ‘relativize’ Rabinowicz’s account and define parity in terms of opposite strict preferences between two items that are only relatively permissible, rather than permissible simpliciter. I argue that this account of parity can be defended if we take seriously the distinction between sufficient and decisive reason for a preference relation. I also show that, on the basis of this distinction, we can arrive at a more extensive taxonomy of value relations than the one proposed by Rabinowicz. (shrink)

Objective: To study the preferences of patients for information related to elective procedures.Methods: A survey was carried out using a sample of 187 women. The majority of whom were on a low-income, who obtained obstetric or gynaecological services at St Joseph Regional Medical Center in Milwaukee, Wisconsin, while they were in a waiting room.Results: Many of the complications, including those that are uncommon and less serious, were considered to be relevant to the medical decisions of most patients. Average seriousness ratings (...) associated with complications of various elective procedures were in the range of moderate to high. A frequency of complications of 1:100 or higher would factor into most women’s elective treatment decisions. Women indicated a preference for receiving as much or more information pertaining to complications associated with particular elective obstetric or gynaecological procedures as other elective procedures.Conclusion: Most women wish to be informed of risks and treatment alternatives, rate many complications as serious, and are likely to use information provided to make elective treatment decisions.

In Rabinowicz (2008), I considered how value relations can best be analysed in terms of fitting pro-attitudes. In the formal model of that paper, fitting pro-attitudes are represented by the class of permissible preference orderings on a domain of items that are being compared. As it turns out, this approach opens up for a multiplicity of different types of value relationships, along with the standard relations of ‘better’, ‘worse’, ‘equally as good as’ and ‘incomparable in value’. Unfortunately, (...) the approach is vulnerable to a number of objections. I believe these objections can be avoided if one re-interprets the underlying notion of preference: instead of treating preference as a ‘dyadic’ attitude directed towards a pair of items, we can think of it as a difference of degree between ‘monadic’ attitudes of favouring. Each such monadic attitude has just one item as its object. Given this re-interpretation, permissible preferences can be modelled by the class of permissible assignments of degrees of favouring to items in the domain. From this construction, we can then recover the old modelling in terms of the class of permissible preference orderings, but the previous objections to that model no longer apply. (shrink)

Socially oriented preferences in decision making and their relation with work and home environment The aim of this paper was to create a psychometric instrument for the measurement of socially oriented preferences in economic decisions made in professional and private life as well as at scrutinizing the effects of various environmental variables on these preferences. For this purpose, two surveys were carried out on a group of adult working Poles. The idea of the new questionnaire and the results of factor (...) analysis are described herein, along with the other examinations confirming the accuracy of the new instrument. A significant correspondence between eight situational factors: five in professional life and three in private life, and the intensity of socially oriented preferences in economic decisions was confirmed. Both surveys showed that these preferences undergo significant alterations along with each slightest change in situational factors, even ones not directly connected with the decision at hand. Moreover, the studies indicate that the intensity of socially oriented preferences vary with respect to gender and age. Practitioner Points: Team goal setting strategy, work style, responsibility and non-financial rewards intense socially oriented preferences. Financial rewards are irrelevant for socially oriented preferences. (shrink)

Socioemotional selectivity theory (SST), an influential life-span theory, suggests that older adults prefer persuasive messages that appeal to emotionally-meaningful goals over messages that appeal to knowledge-related goals, whereas younger adults do not show this preference. A mixed-factorial experiment was conducted to test whether older adults (≥65 years) differ from younger adults (25–45 years) in their preference for emotionally-meaningful appeals over knowledge-related appeals, when appeals are clearly developed in line with SST. For older adults we found the expected (...) class='Hi'>preference for emotionally-meaningful appeals for cancer centers but not for grocery stores and travel organizations. As expected, in most cases, younger adults did not show a preference. Implications for SST-based communication research and for practice are discussed. (shrink)

EEGs were analyzed to investigate the effect of experiences in listening to preferred music in dancers and non-dancers. Participants passively listened to instrumental music of their preferred genre for 2 min, alternate genres, and silence. Both groups showed increased activity for their preferred music compared to non-preferred music in the gamma, beta, and alpha frequency bands. The results suggest all participants' conscious recognition of and affective responses to their familiar music, appreciation of the tempo embedded in their preferred music and (...) emotional arousal, and enhanced attention mechanism for cognitive operations such as memory retrieval. The observed alpha activity is considered in the framework of the alpha functional inhibition hypothesis, in that years of experience listening to their favorite type of music may have honed the cerebral responses to achieve efficient cortical processes. Analyses of the electroencephalogram activity over 100s-long music pieces revealed a difference between dancers and non-dancers in the magnitude of an initial alpha event-related desynchronization and the later development of an alpha event-related synchronization for their preferred music. Dancers exhibited augmented alpha ERD, as well as augmented and uninterrupted alpha ERS over the remaining 80s. This augmentation in dancers is hypothesized to be derived from creative cognition or motor imagery operations developed through their dance experiences. (shrink)

We prove a representation theorem for preference relations over countably infinite lotteries that satisfy a generalized form of the Independence axiom, without assuming Continuity. The representing space consists of lexicographically ordered transfinite sequences of bounded real numbers. This result is generalized to preference orders on abstract superconvex spaces.

Non-compensatory aggregation rules are applied in a variety of problems such as voting theory, multi-criteria analysis, composite indicators, web ranking algorithms and so on. A major open problem is the fact that non-compensability implies the analytical cost of loosing all available information about intensity of preference, i.e. if some variables are measured on interval or ratio scales, they have to be treated as measured on an ordinal scale. Here this problem has been tackled in its most general formulation, that (...) is when mixed measurement scales (interval, ratio and ordinal) are used and both stochastic and fuzzy uncertainties are present. Objectives of this article are first to present a comprehensive review of useful solutions already proposed in the literature and second to advance the state of the art mainly in the theoretical guarantee that weights have the meaning of importance coefficients and they can be summarized in a voting matrix. This is a key result for using non-compensatory Condorcet consistent rules. A proof on the probability of existence of ties in the voting matrix is also developed. (shrink)

The tendency of customers’ preference to their local brands over the foreign ones is known as the consumer ethnocentrism, and it is one of the important issues in international marketing. This study aims at identifying the behavioral and neural correlates of Consumer Ethnocentrism in the field of brand preference by using Event-Related Potential (ERP). We sampled subjects from two ethnic groups, the Chinese ethnic group and the sub-Sahara black Africans group from the Zhejiang University. The subjects faced two (...) sequential stimuli, S1 followed by S2. The S1 consisted of 40 pictures of 20 Chinese and 20 Africans black peoples wearing traditional clothes, and S2 consisted of 40 fake brand-logos which were divided randomly into two groups of 20 each. The subjects were informed that the people in the S1 purchased and recommended the products with the brand-logos presented in S2, and the subjects were asked to rate their preference degree toward these logos. The brand-logos were called the “in-group recommended logos” if the recommender in S1 were the same race as the subjects, otherwise, the “out-group recommended logos”.The results revealed that the race of the brand-logo recommender highly impacted the Chinese subjects’ preference for the brand-logos. The N200 component elicited by in-group recommended logos were significantly lower than those elicited by out-group recommended logos. Besides, there was evidence that being familiar with foreign cultures reduces consumer ethnocentrism. The African subjects were familiar with Chinese people and adopted Chinese culture, as a result, they did not differ in showing preferences between in-group and out-group recommended logos. (shrink)
