The decline in late-life disability prevalence in the United States was one of the most important developments in the well-being of older Americans in the 1980s and 1990s, but there is no guarantee that it will continue into the future. We review the past literature on trends in disability and other health indicators and then estimate the most recent trends in biomarkers and limitations for both the population aged 65 and older and those aged 40 to 64, the future elderly. We then investigate the extent to which trends in education, smoking, and obesity can account for recent trends in limitations and discuss how these three factors might influence future prospects for late-life health. We find that improvements in the health of the older population generally have continued into the first decade of the twenty-first century. The recent increase in the proportion of the younger population needing help with activities of daily living is concerning, as is the doubling of obesity in the last few decades. However, the increase in obesity has recently paused, and favorable trends in education and smoking are encouraging.  相似文献

Abstract

More than 130 million women are subjected to genital mutilation. Despite increasing efforts to reduce the practice, there are many obstacles to eliminating this 2,000-year-old practice, which is based on strong cultural traditions. As college health clinicians provide care to more international students from countries where female genital mutilation is performed, increased awareness and knowledge of the procedure will enable clinicians to understand and manage its complications. We report a case of obstructive uropathy resulting in hydronephrosis secondary to female genital mutilation and review the medical literature regarding this and other complications of genital mutilation “surgery.”  相似文献

Abstract

This study investigated the effects of a 1-h nap on subsequent performance in spatial memory (SM) and logical reasoning (LR) tasks. The objective was to evaluate the duration of the effects of sleep inertia (SI). The performance was measured in two independent groups of subjects. The 1-h nap took place at 00:00 h in group 1 and at 03:00 h in group 2. In each task, the experimental design comprised one no-nap condition in which subjects had no sleep before the night tests, and a nap condition that comprised the 1-h nap followed by the test sessions. To measure the duration of SI effects, the subjects were tested in two 30-min sessions and the data in each session were analysed in sub-units of time of 3 min each. In each task the results showed no effects on accuracy, and no circadian effects of napping were found. In each task, analyses of pooled data of the two groups showed that the performance in the 1-h nap condition exhibited significant reductions of speed immediately following awakening, when compared with no-nap, reflecting SI effects. In SM, the slowing lasted 24 min, and 27 min in LR. Practical implications of the results are discussed.  相似文献

New educational approaches in the preparation of practitioners for the role of change agents in a pluralistic society are examined critically. Necessary changes are the introduction of a crosscultural and change perspective that would permeate the entire curriculum, and the provision of a developmental approach in practice.

Special competence in working with ethnic minorities and cultural groups to understand their aspirations and to formulate policies that would ensure greater justice to them is also necessary. In addition, educational preparation should enhance students' capacity to make judgments in regard to change efforts and strategies and to develop competence in evaluating the effectiveness of social work intervention.  相似文献

Innovating companies increasingly rely on outsourcing to Contract Research Organisations (CROs) for their Research and Development (R&D), which are largely understudied. This paper presents the outcome of a case study in the field of food technology contract research, identifying context specific Key Performance Indicators (KPIs) for a CRO. KPIs were identified with a modified version of the Wageningen Innovation Assessment Tool, with which 72 finished successful and less successful projects were analysed. We developed a benchmarking tool to evaluate starting or running innovation project quality, which allows for direct, in situ project improvements by project leaders at CROs.  相似文献

Abstract

Academic programs in clinical social work often focus on either psychodynamic or systemic approaches. Narrative approaches grounded in postmodern theory also merit attention, as they are well suited for the diverse populations served by social workers. In narrative approaches, practitioners help clients to deconstruct and reconstruct their own life stories, and thereby to empower themselves. This paper compares narrative approaches with psychodynamic and systemic approaches, and suggests ways to integrate their coverage into curricula built around the dominant traditional approaches.  相似文献

Inferences are made concerning population proportions when data are not missing at random.Both one sample and two sample situations are considered with examples in clinical trials.The one samplesituation involves the existence of response related incomplete data in a study conducted to make inferences involving the proportion. The two sample problem involves comparing two treatments in clinical trials when there exists dropouts due to both the treatment and the response to the treatment.Bayes procedures are used in estimating parameters of interest and testing hypotheses of interest in these two situations. An ad-hoc approach to the classical inference is presented for each ofthe two situations and compared with the Bayesian approach discussed. To illustrate the theory developed, data from clinical trials of severe head trauma patients at the Medical College of Virginia Head Injury Center from 1984 to 1987 is considered  相似文献

This paper sets out to investigate the possibility that employees may challenge management through their colonization of work space, facilitated by the transportation of ‘private’ behaviours and activities into the ‘public’ world of organization. It does this within the context of a broader project on the management of emotions within a special care baby unit characterized as a high risk, emergency working environment. Focusing on the experience of night nurses and drawing on the concept of differential space the article seeks to demonstrate how the dominant form of emotion work (characterized as masculine) on the unit may be contested. This is done through the creation of the unit at night as a space of empowerment, achieved through the visible enactment of a feminized form of emotion work. In this sense the analysis explores how the performance of feminine emotion work can be understood as acts of spatial resistance to the authority of the masculine emotion regime. In other words night nurses make the special care baby unit into a space which challenges the masculinist emotion management which dominates the unit. It will be suggested that our understanding of the performance of emotion management practices in particular and management practices in general may be limited if space is ignored.  相似文献
