Hospice organizations are assailed by stiff competition, ever-rising costs, limited funding, and policy changes. Do such pressures stifle the high quality of care these organizations strive to provide? As a case-in-point, we draw from the mid-1990s accounts of caregivers at a nonprofit hospice in a Midwestern city in the United States. We maintain that economic pressures drive organizational restructuring, which then weakens working conditions and, thereby, weakens the staff-client relationship. We discuss effects upon worker behaviors, the worker-client relationship, and client care. This ethnographic case study signals the need to closely examine the threats that current economic and organizational pressures in the United States may pose to the quality of hospice care.  相似文献

This paper applies concepts from the sociology and anthropology of organizations to understand limits to the implementation of a more effective safety culture in the workplace. It highlights unintended consequences of combining bureaucratic control and shared governance and identifies sources of inertia within already existing safety cultures. The data come from focus group interviews with workers in a research and development facility of a multinational corporation in the Western U.S. It is found that safety protocols, rules, and rhetoric, combined with efforts to give workers more responsibility for safety in the workplace, create tendencies toward worker alienation, shame with regard to injuries, complacency, and fear of bureaucratic processes. Therefore it appears that some efforts to create safety culture in the workplace may unintentionally undermine the goal of manufacturing safety.  相似文献

Knowledge Brokering: The missing link in the evidence to action chain?   总被引:1,自引:0,他引:1  
Transferring health care research into policy and practice is a messy and complex process which both policymakers and researchers can struggle with. A potential solution is to use individuals or organisations as knowledge brokers. Using a range of literature, this paper explains the theory behind knowledge brokering, identifies three models of brokering and explores the challenges of brokering. We suggest that clarifying these factors is a significant step towards planning well designed and rigorously evaluated brokering interventions. We also suggest that a clearly defined theoretical framework could help us to find out more about how brokering works and its effectiveness.  相似文献

The Color Additives Scientific Review Panel considered whether there was information sufficient to perform a carcinogenic risk assessment on the colors D&C Red No. 19 (R-19), D&C Red No. 37 (R-37), D&C Orange No. 17 (O-17), D&C Red No. 9 (R-9), D&C Red No. 8 (R-8) and FD&C Red No. 3 (R-3) and to evaluate the assessments sent to FDA as part of the petitions for use of the colors for drug and external uses by the Cosmetic, Toiletry and Fragrance Association (CTFA). There is a lack of human data concerning the colors for making a human health assessment, so the assessments are based upon the extrapolation of animal data. The risk assessments are determined for exposure to single chemicals. Excluded from consideration are possible effects from exposure to multiple chemicals, such as co-carcinogenesis, promotion, synergism, antagonism, etc. In the light of recent efforts in establishing a consensus in risk assessment, the Panel has determined that the CTFA assessments for R-10, O-17, and R-9 are consistent with present acceptable usages, although it questions some of the assumptions used in the assessments. The Panel identified a number of general assumptions made, and discusses their validity, their impact on total uncertainty, and the potential options to address the gaps in understanding that necessitate the assumption. The Panel also derived revised risk estimates using more "reasonable" assumptions than "worst-case" situations, for 90th percentile and average exposure. For those assumptions that are easily quantifiable, the Panel's estimates are less than an order of magnitude lower than the CTFA risk estimates, indicating that the underestimates and overestimates of the CTFA risk estimates tend to balance each other. The impact of most of the assumptions is not quantifiable. The assessment for R-3 is complicated by the fact that there is no good skin penetrance study for this color. It was assumed that the penetrance is similar to that of another water-soluble xanthene color, R-19. It is expected that the absorption of the color is not likely to exceed that of the smaller molecule, R-19. Therefore, the risk estimates are similar to the CTFA estimates, but with different reasoning. The estimates for R-8 and R-37 are different from the others in that there is a lack of any exposure or toxicological information on these colors.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

The perceived severity of the problem of “drift” in the foster care system has encouraged agencies nationwide to accept permanency planning, but perhaps with limited attention to the planning process. This article examines the phenomenon of permanency planning from a planning perspective by focusing on: (a) definition of the permanency planning problem, (b) understanding of issues relevant to permanency planning (caseworker, program and systemic), (c) appreciation of the operational context (political, economic and social factors), and (d) evaluation of available options and possible consequences in developing or improving a permanency planning program. Permanency planning is not a simple, ready-made program applicable to any situation; it involves coordinated efforts by workers, service systems, and society in general, and requires time, commitment and resources. Successful planning for permanency planning can permit more children to grow up in homes providing continuity and stability.  相似文献

This paper explores the contribution of unpaid home activities to the economic welfare of the family. It begins with a review of the conventional economic framework on how household decisions are made. It deals with the modifications which take into account unpaid work in the home. The concept of ‘imputed income’ from home activities (like housework and child care) is then introduced before several possible methods of measuring that income are assessed. The final section of the paper analyses some policy implications which follow from recognizing imputed income as part of family income.  相似文献

The present research examined gender differences in community corrections officers' (CCOs') attributions for child sexual offending. Eighty-five CCOs were asked to write down the reasons why they thought men sexually abused children, and then rate their reasons using Benson's Attributional Dimensions Scale. The results found that CCOs' reasons regarding why men sexually abuse children strongly paralleled current scientific theories on the etiology of child sexual abuse. Also, significant gender differences were found regarding the frequency with which participants cited certain types of reasons for child sexual abuse. Female CCOs were more likely to cite power and control as a reason, while male CCOs were more likely to cite psychopathology as a reason for child sexual abuse. No other gender differences were found. The research, clinical, and educational implications pertaining to these findings are discussed.  相似文献

1. Nursing observation is a key component of psychiatric inpatient nursing care. 2. Patients' experiences of being observed are strongly influenced by the attitudes and behaviors of the observing nurses. 3. Patients prefer to be observed by nurses they know and who talk to them.  相似文献
