An approach to deal with user preference relations, instead of absolute ratings, in recommender systems is discussed. User’s preferences are then ratings expressed qualitatively by using linguistic terms. This is a suitable technique when preferences are imprecise and vague. On the other hand, to avoid that the overall item rating may hide the users’ preferences heterogeneity and mislead the sy...

In three experiments, we examined the effect of response-outcome relations on human ratings of causal efficacy and demonstrated that such efficacy ratings transfer to novel situations through derived stimulus relations. Causal efficacy ratings were higher, and probability of an outcome given a response was lower, for a differential reinforcement of high rate schedule than for either a different...

Collaborative filtering based recommender systems exploit users preferences about items to provide recommendations to these users. These preferences are generally ratings. However, choosing a rating is not an easy task for any user ; the rating value may be influenced by many factors and the ratings are thus not completely trustworthy. In this article, we propose a new approach of expressing pr...

Collaborative filtering-based recommender systems exploit user preferences about items to provide them with recommendations. These preferences are generally ratings. However, choosing a rating is no easy task for any user; the rating scale is usually reduced and the rating values given by the users may be influenced by many factors. The ratings are thus not completely trustworthy. This paper is...

BACKGROUND Prenatal cocaine exposure is a marker of developmental risk. Social environmental risk factors may include maternal stress and maternal perceptions of difficult infant temperament. OBJECTIVES To examine factors that may predict or moderate maternal ratings of parenting stress and difficult temperament in cocaine-exposed (CE) infants. METHOD Neonatal behavior, infant temperament, ...

Integrative priming refers to the facilitated recognition of a target word (bench) as a real word following a prime (park). Prior integrative priming studies have used a wide variety of integrative relations including temporal (summer rain), topical (travel book), locative (forest river), and compositional (peach pie) relations. Yet differences in the types of integrative relations may yield di...

Thin slice ratings of personality have been shown to predict a number of outcomes, but have yet to be examined in the context of psychotherapy. In a sample of 66 clients participating in cognitive therapy for depression, we examined the predictive utility of thin slice rated pre-treatment client traits. On the basis of short video clip excerpts (i.e., thin slices) of intake assessments, trained...

This study examines the empirical relations between the governance structure of public corporations in the United States and the rating and pricing of their debt securities. We study an unbalanced panel of 775 unique U.S. firms from 2001 through 2007 and identify several statistically significant relations between corporate governance factors and credit ratings, bond spreads and firm values. We...

The Social Relations Model is well-known for analyses of interpersonal attraction. As a novelty in this paper, the model is applied to assess different effects on likability ratings from speech only. A group of 30 unacquainted participants is considered in our experiment. Their voices were recorded and transmitted through communication channels, and ratings of speech likability and speaker pers...
