While much is understood about the outcomes of different leadership styles, less is known about the antecedents of leadership, particularly with regards to how leaders' own psychological well-being impacts leadership behaviors. Using conservation of resources theory as a framework, we investigated the relationship between leaders' depleted resources and their leadership behaviors. Conceptualizing depressive symptoms, anxiety, and workplace alcohol consumption as resource depletion, we predicted that depletion would be associated with lower levels of transformational leadership, and higher levels of abusive supervision, and when taken together, would further exacerbate these effects on leadership behaviors. In a study of 172 leader–subordinate pairs, leaders' depressive symptoms, anxiety, and workplace alcohol consumption separately predicted lower transformational leadership, and higher abusive supervision. Furthermore, partial support was found for an exacerbating effect on transformational leadership and abusive supervision.  相似文献

One of the most stigmatized health areas is mental health, so the feasibility of a self-help organization to assist those with the common mental illness, schizophrenia, was contemplated with some misgivings by the Victorian Mental Health Authority in 1977. However, as it was departmental policy to encourage community involvement in alleviating mental illness and its associated problems, a number of relatives of people with schizophrenia were contacted to assess their reaction to the proposition. The response was positive and eight relatives agreed to become a steering committee to organize a public meeting to put forward the idea of forming a self-help organization centred on schizophrenia.  相似文献

Abstract

“The Incidence of Primary Cardiac Arrest During Vigorous Exercise,” David S. Siscovick, et al. To examine the risk of primary cardiac arrest during vigorous exercise, we interviewed the wives of 133 men without known prior heart disease who had had primary cardiac arrest. Cases were classified according to their activity at the time of cardiac arrest and the amount of their habitual vigorous activity. From interviews with wives of a random sample of healthy men, we estimated the amount of time members of the community spent in vigorous activity.

Among men with low levels of habitual activity, the relative risk of cardiac arrest during exercise compared with that of other times was 56 (95% confidence limits, 23 to 131). The risk during exercise among men at the highest level of habitual activity was also elevated, but only by a factor of 5 (95% confidence limits, 2 to 14). However, among the habitually vigorous men, the overall risk of cardiac arrest—i.e., during and not during vigorous activity—was only 40% that of the sedentary men (95% confidence limits, 0.23 to 0.67).

Although the risk of primary cardiac arrest is transiently increased during vigorous exercise, habitual vigorous exercise is associated with an overall decreased risk of primary cardiac arrest. (New England Journal of Medicine 1984;311:874-7.)

“Osteoporosis in Women with Anorexia Nervosa,” Nancy A. Rigotti, et al. Because estrogen deficiency predisposes to osteoporosis, we assessed the skeletal mass of women with anorexia nervosa, using direct photon absorptiometry to measure radial bone density in 18 anorectic women and 28 normal controls. The patients with anorexia had significantly reduced mean bone density as compared with the controls (0.64 ±0.06 vs. 0.72 ±0.04 g per square centimeter, P < 0.001). Vertebral compression fractures developed in two patients, and bone biopsy in one of them demonstrated osteoporosis. Bone density in the patients was not related to the estradiol level (r = 0.02). Levels of parathyroid hormone, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D were normal despite low calcium intakes.

The patients with anorexia who reported a high physical activity level had a greater bone density than the patients who were less active (P < 0.001); this difference could not be accounted for by differences in age, relative weight, duration of illness, or serum estradiol levels. The bone density of physically active patients did not differ from that of active or sedentary controls.

We conclude that women with anorexia nervosa have a reduced bone mass due to osteoporosis, but that a high level of physical activity may protect their skeletons. (New England Journal of Medicine 1984;311:1601-6.)  相似文献

The present study compared the level of conduct problems at age 17 in a large nonclinical sample of adopted participants placed in infancy and children in non-adoptive families matched to the adoptive families on demographic characteristics. Higher levels of adolescent and parent adoption satisfaction were associated with lower levels of conduct problems. Gender by adoption status interactions were not significant. However, female adopted participants had higher levels of conduct problems than female non-adopted participants, whereas male adopted and non-adopted participants had similar levels of conduct problems. In the overall sample, differences between adopted and matched control participants on all conduct problem measures were nonsignificant.  相似文献

Sport, in particular football, constitutes one of the most dynamic, sociologically illuminating domains of globalization. This paper examines the globalization of football with particular reference to Robertson's theorizations of global processes. We examine football's cultural globalization through the concept of 'glocalization', which highlights the interdependence of local and global processes within the game's identities and institutions. We address economic globalization in football by considering the world's leading clubs as 'glocal' transnational corporations. We assess the political globalization of football with reference to the possible enhancement of democracy within the game's international governance. We conclude by affirming the utility of sport in advancing our empirical and theoretical understanding of globalization processes.  相似文献

This paper examines the political economy of public employment, specifically the impact of labor unions on public employment across 20 OECD nations during the 1965–1983 period. A theoretical paradigm based on exchange theory is used to explain the rationale for organized labor’s role in public employment. A model is then presented and tested to explain variation in public employment levels across the 20 nations. The results of the analyses support the central hypothesis that labor union power is positively correlated with public employment. Following the data analysis, the conclusions and implications of the findings are discussed as they pertain to the political economy in advanced industrial democracies.  相似文献

This paper analyzes the extent to which intimate relationships established by contract differ from, and are more egalitarian than, those established by traditional legal marriage. Three types of intimate contracts are examined: contracts between legally married spouses, contracts written as a prelude to legal marriage, and contracts written by unmarried cohabitors as an alternative to legal marriage. The paper addresses two major questions: (1) To what extent do the relationships established by contract differ from those established by legal marriage? (2) To what extent do these contracts support more egalitarian family forms? While considerable variation by type of relationship was found, with the cohabitors departing the most from the traditional legal model, even the married couples wrote contracts that were significantly different from the model imposed by law. They were much more likely to structure their relationship as a partnership rather than as a hierarchy, and to hold their income and property as community property. Further, they were more likely to share the responsibilities for both economic support and homemaking tasks (in contrast to the legal assignment of these duties on the basis of sex). Thus, when compared to the relationships established by law, the 50 intimate contracts in this sample seemed to support more egalitarian family forms.  相似文献
