The distribution of points (r
n,r
n+s), n = 0, 1, 2,...whose coordinates are terms at distance s of the pseudorandom sequence generated by the Wichmann and Hill method is studied. It is known that for many congruential generators critical values of the distance s exist such that these points, far from being uniformly distributed, are concentrated on very few lines. An algorithm is described for computing the critical distances within the Wichmann-Hill sequence and the results obtained are compared with those of other linear congruential generators. 相似文献

The present longitudinal study examined resting heart rate and heart rate variability and reactivity to a stressful gambling task in adopted adolescents with aggressive, delinquent, or internalizing behavior problems and adopted adolescents without behavior problems (total N=151). Early‐onset delinquent adolescents showed heart rate hyporeactivity to the stress‐eliciting gambling task compared to late‐onset delinquent adolescents and adolescents without behavior problems. Heart rate, heart rate variability, and reactivity to stress were not related to environmental factors such as early‐childhood parental sensitivity, parental socioeconomic status, or adoptee's health status at arrival. We conclude that the distinction between delinquency and aggression and between childhood‐onset and adolescence‐onset delinquency is important for the study of stress reactivity in adolescents. 相似文献

This paper reports a further empirical validation of the Demand-Control-Support Model (DCS model), which was developed by Johnson and colleagues (1988, 1989). Data were collected from a heterogeneous group of health-care professionals (nurses and nurses' aides; n = 249). Three major refinements were made to the validation of the DCS Model. First, all relationships in the model were estimated simultaneously by means of covariance structure modelling (LISREL 8). Second, the control dimension was refined substantially, using a psychometrically more sound assessment of the workers' autonomy. Third, the model was applied to the work of health-care professionals. The data did not confirm the assumption that both job strain and motivation are multiplicative functions of job demands, autonomy and social support. First, the results suggested that high levels of autonomy attenuate the increase of emotional exhaustion due to job demands. These results partially supported Karasek's Job Demand-Control Model (Karasek 1979). Second, high levels of social support proved to attenuate the increase of emotional exhaustion due to autonomy. Finally, the main effect of autonomy on job challenge implied that an increase in autonomy is accompanied by an increase in job challenge (and, consequently, job involvement). In addition, low job demands and a high amount of work-related support seem to reduce feelings of exhaustion and, consequently, health complaints. 相似文献

The distinction between affect and cognition was studied in a sample of early breast cancer patients. As assumed by Mckennell (1978) the change experienced led to a level of affect that was lower than the level of cognition and an increased discrepancy between these two components of quality of life within the first year after surgery. Cognition was stable over time, whereas affect improved (p<0.05). The relation between concommitants of disease and treatment and the types of affect-cognition combination were explored. 相似文献

The aim of this paper is to find an empirical connection between the striking increase in the use of fixed-term contracts in Spain and the observed delay in the age at marriage and maternity. Using the eight waves of individual information from the European Household Panel for Spain, we find that for men, the decision whether to get married is strongly negatively affected by holding unstable contracts or not working, relative to when an indefinite contract is held. However, for women, results suggest that holding fixed-term contracts is not a deterrent for the decision whether to get married. With respect to the decision of whether to enter into parenthood, results indicate that for all childless women, either with no partner, holding fixed-term contracts delays entry into motherhood relative to the holding of indefinite contracts. The discouragement effect is stronger for women with no partner, though.JEL classification: D1, J1 相似文献
