Corr JA 《Science of aging knowledge environment : SAGE KE》2004,2004(41):pe38
The use of nonhuman primates, particularly rhesus macaques (Macaca mulatta), as the best model for human physiological and cognitive aging is broadly accepted. Studies employing nonhuman primates to investigate behavioral changes that may occur with increasing age, however, are not common mostly because of the unavailability of appropriate subjects. Recent longitudinal human studies suggest that individual personality might play a large role in aging "successfully" and in the retention of high levels of cognition into old age. As a result of the demographic trend of increasing numbers of aged monkeys and apes in captivity, an opportunity exists to further investigate behavioral aging using the monkey model. 相似文献

The immaturity of the evidence base in some areas of child welfare practice demands that practitioners approach the development and refinement of practice in a systematic way that explicitly seeks to build on and learn from experience. The efforts of public child welfare agencies in Boston and Cleveland show that it is possible to draw on a broader base of knowledge and experience while responding to unique conditions and circumstances in each agency's community. 相似文献

This paper describes a case study in the application of a productivity analysis model in a plant producing industrial gases. Although the process is a relatively simple one, several inputs (labour, electricity, capital and some materials) and several outputs (liquid and gaseous oxygen, gaseous nitrogen, argon and a hydrogen-nitrogen mixture) are involved. The case study demonstrates how measures of total input and total output can be applied and analyses the performance of the plant over a 15-month period in terms of a variety of managerial control ratios. 相似文献

Abstract In a national study of the work environment, physical, and mental well-being of more than 2600 Swedish nurses, 30% reported having experienced violence at work. Possible association between violence and a range of occupational, demographic, and lifestyle characteristics were studied. Stepwise multiple linear and logistic regressions were used to further examine risk factors for violence. Occupational factors with significant correlations to workplace violence were nursing discipline (type of ward or facility), years of work experience, supervisory responsibilities, night work, work dissatisfaction, work-related musculoskeletal injury, and frequency of patient handling. Demographic/lifestyle factors related to violence were age, gender, smoking, coffee consumption at work, and use of alcohol to relax after work. The best fit linear regression model explained 17% of the variance in violence, 13%, of the variance in threat of violence. The logistic regression model confirmed an increased risk of violence and threats in psychiatric and geriatric settings. However, much remains unexplained about the aetiology of violencc in health carc settings. This report provides the basis for a pilot intervention study currently in progress. 相似文献

Abstract This study uses data from a series of comparative case studies to analyse the interorganizational networks of business associations providing workforce development services in the United States. Three aspects of the networks were of particular interest, including (a) the form the partnerships took, (b) the trade-off to involving educational or community vs. business partners in providing workforce development services and (c) the strengths of associations in brokering services to adults or youth. The findings demonstrate that business associations work in intermediary networks or provide their services directly. The conclusions suggest that human resource development professionals should work more actively with local business associations to recruit, train and provide supports for workers in US firms. 相似文献

This paper uses qualitative data from interviews with 118 young Londoners (age 12–18) to examine how the universal provision of free bus travel has affected young people’s independent mobility. Drawing on Sen’s capabilities approach, we argue that free bus travel enhanced young Londoners’ capabilities to shape their daily mobility, both directly by increasing financial access and indirectly by facilitating the acquisition of the necessary skills, travelling companions and confidence. These capabilities in turn extended both opportunity freedoms (e.g. facilitating non-‘necessary’ recreational and social trips) and process freedoms (e.g. feeling more independent by decreasing reliance on parents). Moreover, the universal nature of the entitlement rendered buses a socially inclusive way for groups to travel and spend time together, thereby enhancing group-level capabilities. We believe this attention to individual and group capabilities for self-determination provides the basis for a broader and more child-centred view of independent mobility than the typical research focus upon travelling without an adult and acquiring parental permissions. 相似文献
