The purpose of this note is to compute the probability of logrolling for three different probabilistic cultures. The primary finding is that the restriction of preferences to be in accord with the condition of separable preferences creates enough additional structure among voters’ preference rankings to create an increase in the likelihood that a Condorcet winner will exist with both IC and IAC...

This paper describes a method for planning with rich qualitative, temporally extended preferences (QTEPs) using lookahead heuristics inspired by those employed in state-of-the-art classical planners. Key to our approach is a transformation of the planning domain into an equivalent but simplified planning domain. First, compound preference formulae are transformed into simpler, equivalent prefer...

o bjectives: smoking may impact oral self-care (osc) .   this study aimed to analyze the role of smoking in osc among iranian dental health professionals. materials and methods: the cross-sectional data were collected at two annual dental meetings and seven randomly selected dental schools in iran. a total of 1,459 respond- ents composed of 967 general dental practitioners (gdps), 229 dental ed...

We consider voting over combinatorial domains, where alternatives are binary tuples. We assume that votes are specified as conditionally lexicographic preferences, or LP trees. We study aggregation problems of LP tree votes for several positional scoring rules. Our main goal is to demonstrate that answer-set programming can be effective in solving the winner and the evaluation problems for inst...

This article tries to explain the exceptional levels of knowledge creation in certain industrial clusters, levels that are seemingly higher than what is implied by the usual models of atomistic agents who do not internalize externalities. For this purpose, we introduce reference-dependent utility into an OLG model of an industrial cluster where agents allocate resources between consumption and ...

Core-selection is a crucial property of social choice functions, or rules, in social choice literature. It is also desirable to address the incentive of agents to cheat by misreporting their preferences. This paper investigates an exchange problem where each agent may have multiple indivisible goods, agents’ preferences over sets of goods are assumed to be lexicographic, and side payments are n...

Understanding the preferences of patients and health professionals is useful for health policy and planning. Discrete choice experiments (DCEs) are a quantitative technique for eliciting preferences that can be used in the absence of revealed preference data. The method involves asking individuals to state their preference over hypothetical alternative scenarios, goods or services. Each alterna...

In the context of the current debate about teaching reading, research to ascertain primary teachers’ personal and professional reading practices was undertaken. The study explored teachers’ reading habits and preferences, investigated their knowledge of children's literature, and documented their reported use of such texts and involvement with library services. Questionnaire responses were gath...

We derive necessary and sufficient conditions in order for binary voting choices over a finite number of pairs of alternatives to be consistent with voter preferences that admit concave utility representations. These conditions imply simple testable restrictions on the location of voters’ ideal points, and can be used to predict individual voting behavior. On the other hand, if the location of ...

People’s choices can be predicted given information about their preferences. Learning people’s preferences is the inverse problem of inferring preferences from choices. Given the apparent relationship between choice prediction and preference learning, it is natural to ask whether the two are mutually consistent. Given weak assumptions, we show that no single, consistent model of the relationshi...
