We examine the representation of judgements of stochastic independence in probabilistic logics. We focus on a relational logic where (i) judgements of stochastic independence are encoded by directed acyclic graphs, and (ii) probabilistic assessments are flexible in the sense that they are not required to specify a single probability measure. We discuss issues of knowledge representation and inference that arise from our particular combination of graphs, stochastic independence, logical formulas and probabilistic assessments.  相似文献

When possible, Rational Emotive Behavior Therapy (REBT) has always aimed for thorough-going philosophic change. It instructs people to transform their fundamental approach to life and shows them how to become (1) less prone to disturbance and (2) active seekers of that which, for them, constitutes the zoom of living. Rather than spend time telling people the meaning of life, REBT shows them how they may more frequently, more intensely and for longer periods of time have the experience of full and deep living. By doing so, REBT can well be seen as a source of spiritual transformation.  相似文献

This study examined the availability and helpfulness of twenty new employee development tactics and their relationship with seven job attitudes. Bachelor's graduates surveyed twelve months after graduation (n = 378) reported low availability of many tactics but high perceived helpfulness. Multiple regression analyses revealed strong correlations (R = .50–.58) with satisfaction, commitment, intent to quit, psychological success, and post-decision dissonance. The most important tactic was allowing new employees to fully utilize their skills and abilities. Implications for new approaches to new employee development in organizations and for human resource professionals are discussed.  相似文献

We examined the effects of retrieval practice for students who varied in working memory capacity as a function of the lag between study of material and its initial test, whether or not feedback was given after the test, and the retention interval of the final test. We sought to determine whether a blend of these conditions exists that maximises benefits from retrieval practice for lower and higher working memory capacity students. College students learned general knowledge facts and then restudied the facts or were tested on them (with or without feedback) at lags of 0–9 intervening items. Final cued recall performance was better for tested items than for restudied items after both 10 minutes and 2 days, particularly for longer study–test lags. Furthermore, on the 2-day delayed test the benefits from retrieval practice with feedback were significantly greater for students with lower working memory capacity than for students with higher working memory capacity (r?=??.42). Retrieval practice may be an especially effective learning strategy for lower ability students.  相似文献

Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event‐related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty‐six demographically similar adolescents (ages 9–14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (= 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (= 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (= 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment‐related effects on these neural systems.  相似文献

Understanding team adaptation: a conceptual analysis and model   总被引:2,自引:0,他引:2  
This endeavor provides a multidisciplinary, multilevel, and multiphasic conceptualization of team adaptation with theoretical roots in the cognitive, human factors, and industrial-organizational psychology literature. Team adaptation and the emergent nature of adaptive team performance are defined from a multilevel, theoretical standpoint. An input-throughput-output model is advanced to illustrate a series of phases unfolding over time that constitute the core processes and emergent states underlying adaptive team performance and contributing to team adaptation. The cross-level mixed-determinants model highlights team adaptation in a nomological network of lawful relations. Testable propositions, practical implications, and directions for further research in this area are also advanced.  相似文献

Achieving a preventive attitude is the first step in eliminating cancer risk behaviours. This cross-sectional study evaluated the attitude towards the European Code against Cancer, in 3,031 relatives of cancer patients. The study looked for keys to improve attitude by means of educational interventions. Attitude was evaluated using a questionnaire with 63 items and a Likert's scale. Measured from -2 to +2 , the mean score was 0.905 [0.894 - 0.971]. Five per cent had a mean score under 0.38 and another 5% over 1.46. A multivariate analysis found that age, sex and level of education were significantly associated with attitude: young men with a low cultural level were those with the lowest preventive attitude. The family history of cancer was not associated with attitude. Educational interventions should modify the perceived advantages of smoking and drinking, and the disadvantages related to preventive diet and sun and workplace protection.  相似文献

Male humpback whales (Megaptera novaeangliae) produce long, structured sequences of sound underwater, commonly called songs. Humpbacks progressively modify their songs over time in ways that suggest that individuals are copying song elements that they hear being used by other singers. Little is known about the factors that determine how whales learn from their auditory experiences. Song learning in birds is better understood and appears to be constrained by stable core attributes such as species-specific sound repertoires and song syntax. To clarify whether similar constraints exist for song learning by humpbacks, we analyzed changes over 14 years in the sounds used by humpback whales singing in Hawaiian waters. We found that although the properties of individual sounds within songs are quite variable over time, the overall distribution of certain acoustic features within the repertoire appears to be stable. In particular, our findings suggest that species-specific constraints on temporal features of song sounds determine song form, whereas spectral variability allows whales to flexibly adapt song elements.Electronic Supplementary Material Supplementary material is available for this article at .  相似文献

In this article, the authors present a model linking immediate affective experiences to within-person performance. First, the authors define a time structure for performance (the performance episode) that is commensurate with the dynamic nature of affect. Next, the authors examine the core cognitive and regulatory processes that determine performance for 1 person during any particular episode. Third, the authors describe how various emotions and moods influence the intermediary performance processes, thereby affecting performance. In the final section of the article, the authors discuss limitations, future research directions, and practical implications for their episodic process model of affect and performance.  相似文献
