The purpose of this investigation was to study the effects of an acute bout of aerobic exercise on state anxiety of women while controlling for iron status (hemoglobin and serum ferritin). Participants were 24 active women, ages 18-20 years (n = 12) and 35-45 years (n = 12). In addition to a nonexercise control condition, participants completed one exercise bout at 60% maximal oxygen uptake (VO2max) and one at 80% VO2max. Each exercise session consisted of a 33-min bout in which participants exercised at their target intensities for a 20-min segment. Immediately before each exercise trial, participants were given the Spielberger State Anxiety Inventory (SAI). The SAI was again administered immediately following the exercise session and at 30, 60, and 90 min postexercise. Data were analyzed using an Age x Intensity x Time (2 x 3 x 5) repeated measures analysis of covariance (ANCOVA) with iron status serving as the covariate. The ANCOVA on state anxiety yielded significant effects for time (p < .0001, eta2(p) = .48), the Intensity x Time interaction (p = .0006, eta2(p) = .19), and the Intensity x Age interaction (p = .04, eta2(p) = .15). All three exercise conditions (including control) showed a decline in state anxiety across time, but the 80% VO2max condition showed a sharper decline. Intensity of exercise conditions did not differ in state anxiety at baseline or immediately after exercise, but a difference favoring the 80% VO2max condition over the control condition emerged at 30 min postexercise. After controlling for iron status, older women who exercised at 80% VO2max exhibited lower SAI scores compared to the control condition. 相似文献

The article sets out to pose the question ‘Is it possible for an archive to aid the process of reconciliation?’ Is the scale of a given event, in some cases, insurmountable in terms of reconciling the parties? The graphic nature of the archives and the issue of psychological impact of an archive on the archivist is explored. It is contended that through outreach and dissemination of the contents of the archive, it is possible to provide to the affected communities the information of what the international community has done in terms of judicial redress. Archives can also fulfil-dual roles and this issue is touched upon in that the purpose and organization of the archive is changing from an active records center or a tool of repression to suit a future audience of researchers or to aid reconciliation. 相似文献

This article reports the results of a study of the extent of management development programmes for managers of universities. The method used was a postal survey of all UK universities, which produced a response of over 60 per cent of universities. According to the responses received, about half of UK universities provide some organised management development for their managers with the other half doing nothing to develop their managers in any systematic way. On this basis, universities provide less management development for their managers than most other UK organisations. A few universities have achieved, and some are intending to seek, the Investors in People standard. Personnel managers within the universities are convinced of the need for management development for those who manage our universities. However, lack of resources and lack of commitment from vice-chancellors and other senior academics are the main barriers to the successful implementation of systematic management development. 相似文献
