The present study uses canonical analysis to examine the contingency model of organizations in the nursing home field. Data on environmental pressures and managerial practices relevant to the decision-making process are analyzed. Results support the theory that managerial practices are contingent on environmental pressures. The implications of these results for health-care decision makers and for future assessments of managerial-environmental relationships are discussed. 相似文献

This paper presents a minimum-cost methodology for determining a statistical sampling plan in substantive audit tests. In this model, the auditor specifies β, the risk of accepting an account balance as correct when it is not, according to audit evidence requirements. Using β as a constraint, the auditor then selects a sampling plan to optimize the trade-off between sampling costs and the costs of follow-up audit procedures. Tables to aid in this process and an illustration are provided. 相似文献

This article examines the relationship between refugees andthe regional dynamics of peacebuilding. It argues that recentapproaches to peacebuilding have adopted a narrow understandingof conflict. The article outlines the links between protractedrefugee situations and regional insecurity to argue that therelationship between peacebuilding and refugees goes beyondrepatriation. Instead, the presence of "spoilers" within therefugee-populated areas, the potential for early and forcedrepatriation, and the politicization of refugees while in exilehave all the proven potential to undermine peacebuilding efforts,while the experience of exile may enable refugees to contributeto the peacebuilding process. 相似文献

This paper examines the evidence base for interventions which seek to enhance social support resources for families with children at risk of adverse developmental outcomes. Substantive and methodological issues related to the implementation of social support interventions are discussed and a research agenda for the development, testing and evaluation of such interventions is presented. 相似文献

The global factory literature suggests that MNCs can take advantage of global operations by extensively offshoring and outsourcing activities. However, the added difficulty for the lead firm to coordinate the resulting complex structure is often underestimated. Evidence could be found in Boeing's 787 Dreamliner project, in which the external complexity disrupted MNC performance. Motivated by the gap between theory and practice, this study focuses on systems of MNCs connected with each other with supplier-client relationships and/or outsourcing. In particular it investigates the interplay of the internal and external complexity in such systems and how their balance affects the system performance. The study models the internal and external complexity by using the NKC-simulation methodology and adjusting it to the specific MNC context. The NKC methodology is widely used in organization theory to study complex systems. Simulations comparing the performance of MNCs that use outsourcing to different degrees indicate that a balanced level of internal and external complexity is beneficial in the context of global factory. 相似文献

Multigenerational households are increasingly affecting both the individual and family as well as community organizations and social policies. Social work and other family studies students can profit from educational modalities that use adult learning applications through a systems life-course perspective, the whole family aging over time. Family simulation software—addressing multigenerational families, such as two or more adult generations living together—builds on a previous paper (Marriage & Family Review, Feb. 2015). Social class, among other demographic and environmental variables, is emphasized. Agent-based family social network simulation of multigenerational families can facilitate experiential learning. An automatically generated life events report, based on both factual data and specific family characteristics, can be used as a classroom case study for role playing and assessing. 相似文献

The Youth Court in Schools Project was implemented in two low-income, violent, racially/ethnically diverse rural counties. This study examined if the presence of Youth Court impacted students’ perceptions of school danger, individual functioning, and interpersonal relationships. Data were gathered from 3454 youth; following multiple imputation, data were analyzed using paired samples t tests. Results indicated that perceptions of school danger increased significantly and self-esteem decreased significantly in the control schools pretest to posttest. Violent behavior, anxiety, friend rejection, and bullying victimization decreased significantly in the Youth Court intervention schools pretest to posttest, but did not change significantly in the control schools. Findings provide preliminary evidence that Youth Court is an effective way of improving school climate, individual functioning, and interpersonal relationships. 相似文献

Certain motor vehicle safety standards stipulate a collision test speed and a set of performance criteria that vehicles must satisfy during or after the collision test. For example, Federal Motor Vehicle Safety Standard 301 requires a 30 mile per hour (mph) barrier collision and specifies a certain maximum allowable limit on the total spillage of fuel. Vehicle designs are required to meet this standard; however, when collision tests are conducted at speeds higher than the standard, vehicles do not always satisfy the performance criteria. This paper develops a mathematical model for estimating the probability of meeting the standard by using a Bayesian framework to incorporate engineering judgment with collision test results. The model is based on the idea that there are random features to a vehicle's ability to meet performance standards in a collision, especially at such elevated speeds. Example calculations are included to illustrate the estimation of the probability of meeting the standard and to compare it with a maximum likelihood approach. 相似文献
