It is shown that certain correlation measures suggested by information theory are simple functions of the determinants of the correlation matrices involved, if multivariate normality is assumed. This illuminates and in a sense strengthens Rozeboom's point in [3], that information theoretical statistics have classical correlational counterparts. 相似文献

Change in cognitive abilities was assessed over a 6-year period in a sample of monozygotic and same-sex dizygotic twin pairs (N = 507 individuals), aged 80 and older (mean age = 83.3 years: SD = 3.1). who remained nondemented over the course of the study. Latent growth models (LGMs) show that chronological age and time to death are consistent predictors of decline in measures of memory, reasoning, speed, and verbal abilities. Multivariate LGM analysis resulted in weak and often negative correlations among rates of change between individuals within twin pairs, indicating greater differential change within twin pairs than occurs on average across twin pairs. These findings highlight several challenges for estimating genetic sources of variance in the context of compromised health and mortality-related change. 相似文献

Participation in leisure-time activities, self-concept perceptions and individual dispositional goal orientations were examined as mediators of relationships between physical coordination and self-evaluations of life satisfaction and general self-concept for 173 boys aged 10-13 years. Participants completed seven-day activity diaries and 12-month retrospective recall questionnaires recording participation in leisure-time activities. Self-report measures of self-concept, global life satisfaction and dispositional goal orientations were also completed. Results showed that boys with moderate to severe physical coordination difficulties had significantly lower self-concept perceptions of physical ability and appearance, peer and parent relations and general self-concept, as well as lower life satisfaction than boys with medium to high levels of physical coordination. The relationships between boys' physical coordination and their self-perceptions of life satisfaction and general self-concept were significantly influenced by individual self-concept appraisals of physical ability and appearance, peer and parent relations. Adopting task-oriented goals was found to positively change the relationship between physical coordination and both general self-concept and life satisfaction. Team sport participation positively mediated the relationship between physical coordination and life satisfaction. The potential for team sport participation and adoption of task-oriented goals to influence life satisfaction for boys with differing levels of physical coordination was discussed. 相似文献

Abstract This paper is based on the authors' experiences of conducting short-term psychodynamic group therapy with university students. The therapy groups focus on common problems among the members, i.e. perfectionism, procrastination, and fear of graduation. Working on their dependency and on their inadequate separation from parental figures typically helps the students cope more creatively with their academic problems. The paper explores technical questions and possible advantages in working within a short time frame using a group analytic approach. 相似文献

This study investigates the characteristics of whistleblowers, the prevalence and nature of whistleblowing, and the occurrence of retaliation after whistleblowing using a randomly selected and representative sample of Norwegian employees. The results showed that 12 per cent self-reported as whistleblowers according to an operational definition. Being a leader, or a union or personnel safety representative was significantly related to whistleblowing. The most frequently reported wrongdoing was harassment conducted by a single colleague. Wrongdoer(s) received mixed responses, from no reaction to reprimand. Even though most whistleblowers were not sanctioned, they reported less job satisfaction and more workplace bullying than did nonwhistleblowers. Only a few were rewarded. For the most part, wrongdoing was stopped or reduced. However, whistleblowing was only partially effective, because whistleblowers reported lack of feedback about the result of their report. Results also showed that the status of the wrongdoer was related to the reaction he or she received afterwards, as were the type of wrongdoing and the effect on the wrongdoing, and the type of wrongdoing and the effect on the wrongdoer(s). Potential explanations for the results, such as the type of sample and power distance, are discussed. Practical implications of the study are also addressed, such as the importance of providing feedback to whistleblowers. 相似文献

We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia. 相似文献

Using Conger’s family stress model as a theoretical framework, a series of mediated associations among economic hardship, perceived economic pressure, parental depression, marital conflict, psychologically controlling parenting, and children’s reticent behaviors in Romanian families were studied. The sample consisted of 121 Romanian mothers and fathers of 4–5-year-old children. Children’s kindergarten teachers living in urban and rural locations evaluated child reticence. Findings generally support the family stress model. Structural equation modeling showed that after controlling for living in a rural location, economic pressure was indirectly linked with marital conflict through depression. Depression was indirectly related to psychological control through marital conflict, and marital conflict was indirectly linked to child reticence through psychological control. Directions for future research and recommendations for interventions and public policy are described. 相似文献
