ResumenEl presente trabajo estudia la influencia de la «discusión grupal» sobre los estados afectivos inducidos. Se esperaba que, después de inducir estados afectivos (positivo vs negativo vs neutro) mediante la visión de secuencias de películas, el contexto de discusión grupal (positivo vs negativo), acentuara o atenuara el efecto del método de inducción. Para ello, se utilizó un diseño experimental en el que participaron un total de 60 sujetos, y en el que se analizaron las respuestas de cada grupo experimental en una tarea de asociación libre de palabras. Nuestros resultados demuestran que el efecto del contexto grupal es más potente que el de la visión de películas cortas, originando un número significativamente mayor de palabras originales en el primer caso que en el segundo. Estos resultados son analizados a la luz de recientes teorías sobre cognición y afecto. 相似文献

The history of gambling in post-socialist countries is noticeably different from that of other countries in Europe. The goal
of this study was therefore twofold: Firstly, to systematically review all European epidemiological studies related to excessive
gambling in the general adult population, and secondly, to provide an overview of the state of gambling in Hungary based on
the first ever nationwide representative survey, setting the results against the backdrop of the earlier European studies.
A systematic review was carried out of European gambling studies which focus on a representative adult general population.
Hungarian data was obtained from the National Survey on Addiction Problems in Hungary general adult population survey (N = 2,710). Pathological gambling was measured by the South Oaks Gambling Screen. Lifetime prevalence of excessive gambling
(problem and pathological gambling) in the general adult population of European countries varies between 1.1% (Italy and Spain)
and 6.5% (Estonia). In Hungary, the prevalence of problem gambling is 1.9%, with pathological gambling at 1.4%. The socio-demographic
characteristics of the results are similar to those of other European countries. Using epidemiological data from the general
adult populations of two post-socialist nations, it was possible to compare the results with data from 12 other European countries.
Based on the data available, the extremely rapid liberation of the gambling market in the post-socialist countries has led
to a similarly swift escalation in associated gambling problems. 相似文献

An appropriate alignment between business strategy, manufacturing strategic objectives and manufacturing capabilities reportedly influences business performance positively. However, few papers empirically analyse this proposition for the case of Porter's generic strategies of cost leadership and differentiation, and none jointly considers all four elements. This paper integrates strategies, capabilities and performance in a single model and proposes that both manufacturing competitive priorities and capabilities, articulated in terms of cost and flexibility, are essential for explaining the link between generic business strategies and business commercial and financial performance. Within this analytic framework, we test whether companies that emphasize one business strategy rather than another achieve a better alignment and superior performance. The analyses conducted with a sample of 148 Spanish manufacturers provide general support for these propositions and contribute to a deeper understanding of the role played by functional strategies in understanding the outcomes of business strategy. 相似文献

In this paper we obtain several influence measures for the multivariate linear general model through the approach proposed by Muñoz-Pichardo et al. (1995), which is based on the concept of conditional bias. An interesting charasteristic of this approach is that it does not require any distributional hypothesis. Appling the obtained results to the multivariate regression model, we obtain some measures proposed by other authors. Nevertheless, on the results obtained in this paper, we emphasize two aspects. First, they provide a theoretical foundation for measures proposed by other authors for the mul¬tivariate regression model. Second, they can be applied to any linear model that can be formulated as a particular case of the multivariate linear general model. In particular, we carry out an application to the multivariate analysis of covariance. 相似文献

In this article power divergences statistics based on sample quantiles are transformed in order to introduce new goodness-of-fit tests. Quantiles of the distribution of proposed statistics are calculated under uniformity, normality, and exponentiality. Several power comparisons are performed to show that the new tests are generally more powerful than the original ones. 相似文献

Patriota and Lemonte [24] introduced a quite general multivariate normal regression model. This model considers that the mean vector and the covariance matrix share the same vector of parameters. In this paper we present some influence assessment for this model, such as the local influence, total local influence of an individual and generalized leverage which are discussed. Additionally, the normal curvatures for local influence studies are derived under some perturbation schemes. 相似文献
