We analyze different separability conditions that characterize the numerical representability of semiorders through a real-valued function and a strictly positive threshold. Any necessary and sufficient condition for the numerical representability of an interval order by means of two real-valued functions is proved to also characterize the Scott–Suppes representability of semiorders provided that a key additional condition of regularity with respect to sequences holds.  相似文献

This study explores the relationships between spiritual meaning and social support from the religious community and problem behaviors, anger and depression in 128 dementia caregivers. The results suggest a mediating role of anger in the relationship between the appraisal of problem behaviors and depression. Support from the religious community is directly and negatively associated with anger, but the relationship between spiritual meaning and anger is mediated by caregivers’ appraisals of problem behaviors, suggesting that spiritual beliefs might help caregivers to find meaning in caregiving experiences and thus appraise care recipients’ behavioral problems as less stressful.  相似文献

Several parameters related to the timing, grip force and load force involved in a precision grasping task were studied in patients with Parkinson's disease (PD) at different moments of medication and healthy controls, using a sensorized anthropomorphic device which was totally adapted to the human hand. The aim of this work was to carry out an accurate study of the reach-load-grip-hold-place-release subtasks to identify any physical motor impairment, its relation to medication and Parkinsonian strategies. Twenty seven patients in ON and OFF-like medication moments, and twenty seven age-matched controls took part in the experiment, which consisted of using the index finger and the thumb to perform a precision motor task involving different experimental objects. Visual cues were used as distracting elements. Results showed several motor parameters impaired in OFF-like medication moment but attenuated in ON state, suggesting a medication effect on the performance of the task.  相似文献

Social support is a variable that has a great influence in the sport context. In fact, this variable not only affects the athlete's performance but it has also shown to be related to psychological disorders such as Burnout Syndrome. The aim of this paper was to illustrate the Spanish adaptation of a social support scale in the sport context. The normative group who took part in the final version of the research was composed of 397 athletes aged between 13 and 64 years old (mean= 19.23 and standard deviation= 6.67). The scale shows: adequate factorial and construct validity, acceptable fit indexes (Kaiser-Meyer-Olkin= 0.785, Root Mean Square Residual= 0.078; Kelly's criterion= 0.075), a negative correlation with the dimensions of burnout and no relationship with respect to self-esteem. In addition, it also shows high reliability (a= 0.88). Furthermore, statistically significant differences have been found in relation to genders - where women require greater social support. In contrast, males tend to display a lower level of social support with team players and international athletes. Moreover, differential item functioning (DIF) was carried out to explore sex bias, however, none of the items exhibit DIF problems.  相似文献

We report three sentence completion experiments in which we manipulate the emotional dimension of the nouns in a complex noun phrase (NP) that precedes a relative clause (RC), as in the classic ambiguity in Someone shot the servant of the actress who was on the balcony. The aim was to see whether nouns such as orgy or genocide affect the well-established preference of Spanish to adjoin the relative clause high in the tree (to servant instead of actress in the example above). We manipulated the valence and arousal of the lexical entities residing in the NP. Our results indicate that (a) the inclusion of either pleasant or unpleasant words induces changes in the usual NP1 preference found in Spanish; (b) the effects of high-arousal words are especially clear, in that they pull RC adjunction towards the NP where they are located, be it the NP1 or the NP2; and (c) in the context of sentence production, these kinds of words seem intense enough to promote changes in (and even reverse) a solid syntactic bias. We discuss these findings in the light of existing theories of syntactic ambiguity resolution.  相似文献

Functional foods and foods derived from genetically modified organisms represent two forms of intervention in the design of foodstuffs that have given rise to distinct political and regulatory dynamics. In Europe, regulatory agencies have tried, unsuccessfully, to affix a definitive legal meaning to these categories of food artificiality. This incomplete process of legal disambiguation has gone hand in hand with the delegation of the responsibility for overseeing new products to consumers, who are asked to continuously consider and assess the qualities of foods when making their choices in the marketplace. In the case of genetically modified foods, we have witnessed strategies of avoidance premised on the consideration of genetic modification as a blemish on the conventional character of foodstuffs. Functional foods, on the other hand, are increasingly mobilized in practices of naturalistic enhancement. What both examples have in common is the open-ended character of their respective regulatory regimes, and the continuous prodding of consumers to involve themselves more intensely in the weighing of their food choices. The result is a particular mode of market activism that we describe as restless consumption.  相似文献

Resumen

En un análisis de la representación debe distinguirse entre el conocimiento registrado a nivel de la memoria semántica y su uso y manipulación a nivel de la memoria activa, la diferenciación funcional de estos niveles es posible si se especifican los sistemas y mecanismos que intervienen en el procesamiento de información. Los efectos de facilitación e interferencia comúnmente hallados en los paradigmas experimentales de anticipación y Stroop permiten describir algunos de los sistemas y mecanismos que subyacen a las imágenes mentales y a las palabras como distintos tipos de representación simbólica. Frente a una teoría interpretativa, una teoría constructiva explica las propiedades emergentes de las imágenes mentales como el resultado de la actualización de su referencia en un determinado contexto. Distinguiendo entre conocimiento registrado y uso del conocimiento es posible rechazar la perspectiva de Pylyshyn en el análisis de las imágenes mentales. En este artículo, a modo de introducción, presentamos algunos de los trabajos que estudian la base funcional de los efectos de facilitación e interferencia. Estos efectos, que también se especifican, se han venido utilizando para caracterizar los mecanismos que intervienen en el procesamiento de palabras y dibujos. Definiendo estos mecanismos pudra precisarse la naturaleza de las imagenes mentales y cómo se lleva a cabo su interpretación semántica. En los artículos que se presentan se pone de manifiesto que el distinto procesamiento estratégico a que se someten dibujos y palabras depende del proceso de decisión y éste a su vez de las demandas de la tarea.  相似文献

Resumen

El objeto de esta investigación es analizar el proceso de decisión de un jurado bajo condiciones de simulación. A través de dos experimentos en que se manipula la forma de presentación de la información, se estudian los efectos de la regla de decisión y de las instrucciones en el veredicto y los efectos de la deliberación. Se defiende la hipótesis de que la regla de decisión y las instrucciones tienen respectivamente efectos informativos y normativos sobre el veredicto, y que la deliberación tiene efectos informativos. Estos efectos, sin embargo, sólo resultan parcialmente evidentes en el contexto de una estrategia de juicio compensatoria que supone el procesamiento analítico de la evidencia aportada en el juicio. Los resultados muestran que los sujetos cambian de estrategia cuando cambia la forma de presentación y el tipo de respuesta solicitada que es holística, de elección y no compensatoria en la presentación simultánea y analítica, de juicio y compensatoria en la presentación secuencial. Sólo cuando la deliberación supone un cambio de estrategia tiene un efecto sobre el veredicto que es más favorable que lo que lo era inicialmente para el acusado. Los resultados parecen adecuarse a un modelo de acumulación de evidencia que afecta a la evaluación de los ítems incriminatorios del caso.  相似文献

Traditionally, the so-called exemplification or the relation between the particular and the universal has been one of the three central problems making up the classical problem of universals: (1) What is a particular? (2) What is a universal? (3) What is the relation between the particular and the universal? I used the expression “classical problem of universals” instead of “the problem of universals” since the classical formulation of the problem could be said to contain a questionable assumption, namely that substance should be the bearer “in” which are the entities of (other) categories. Under these circumstances, a neutral approach to the problem of universals could consist in reformulating the three problems of the classical problem as follows: (4) What is the fundamental bearer of categories? (5) What categories are there? (6) What is the relation between the fundamental bearer and the categories? My purpose in this paper is to answer the latter three questions. In order to accomplish this task, I shall discuss the views of two leading figures in substance-ontology, Aristotle and Jonathan Lowe, and the views of two leading figures in fact-ontology, Gustav Bergmann and Reinhardt Grossmann. I shall answer the first question by claiming that the fundamental bearer of categories is facts; the second, by pointing out that it depends on the answer to the previous one; and the third, by showing that the relation between the fundamental bearer and the categories is the one between facts and its constituents, not between a substance or particular and its accidents or properties. In this connection, I shall argue that the “in” of property exemplification should be categorially reconstructed in order for entities other than properties, say, particulars, relations, connectives, numbers, and even facts, to be “in” facts. This categorial reconstruction will also argued for with respect to the Principle of Exemplification.  相似文献

ABSTRACT

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.  相似文献
