We study a model in which voters choose between two candidates on the basis of both ideology and competence. While the ideology of the candidates is commonly known, voters are imperfectly informed about competence. Voter preferences, however, are such that it is a dominant strategy to vote according to ideology alone. When voting is compulsory, the candidate of the majority ideology prevails an...

We prove that a universal preference type space exists under much more general conditions than those postulated by Epstein and Wang (1996). To wit, it is enough that preferences can be encoded by a countable collection of continuous functionals, while the preferences themselves need not necessarily be continuous or regular, like, e.g., in the case of lexicographic preferences. The proof relies ...

We used eyetracking, perceptual discrimination, and production tasks to examine the influences of perceptual similarity and linguistic experience on word recognition in nonnative (L2) speech. Eye movements to printed words were tracked while German and Dutch learners of English heard words containing one of three pronunciation variants (/t/, /s/, or /f/) of the interdental fricative /θ/. Irresp...

In designing intelligent web based educational systems different student needs and preferences should be taken into consideration. Personalization of a system usually results in an increase in its effectiveness, which can be measured by the degree to which learning outcomes are achieved. However, taking into account the individual requirements of each learner and adjusting the system to their n...

Providing adaptivity based on learning styles can support learners and make learning easier for them. However, for providing proper adaptivity, the learning styles of learners need to be known first. While most systems, which consider learning styles, use questionnaires in order to identify learning styles, we propose an automatic student modelling approach, which analyses the actual behaviour ...

This paper focuses on the importance that class-formation of optional subjects in school education can affect learners. And it will point out problems about conventionally 'mechanical' class-formation, and suggest a method of class-formation based on multi attribute utility theory, which is taken into consideration students' preferences. Therefore, this paper exercises experiments by a new meth...

This work incorporates Selectional Preferences (SP) into a Semantic Role (SR) Classification system. We learn separate selectional preferences for noun phrases and prepositional phrases and we integrate them in a state-of-the-art SR classification system both in the form of features and individual class predictors. We show that the inclusion of the refined SPs yields statistically significant i...

Each month many women experience an ovulatory cycle that regulates fertility. Whereas research finds that this cycle influences women’s mating preferences, we propose that it might also change women’s political and religious views. Building on theory suggesting that political and religious orientation are linked to reproductive goals, we tested how fertility influenced women’s politics, religio...

Many preference aggregation problems are not, by nature, one-shot. In these settings, voter preferences need to be repeatedly aggregated as a function of the underlying pool of options that are being voted over. For example, imagine that a firm votes an offer to a candidate. If the offer is declined, then the pool of options shrinks, votes are aggregated once more, and a subsequent offer is mad...
