This paper reviews recent developments in the stochastic comparison of order statistics. The results discussed are basically: (l) Stochastic comparisons of linear combinations of order statistics from distributions F and G where G?1 F is convex or starshaped. (2) Stochastic comparisons of individual order statistics and of vectors of order statistics from underlying heterogeneous distributions by the use of majorization and Schur function theory. (3) Stochastic comparison of random processes. Applications to reliability problems are presented illustrating the use and value of the theoretical results described  相似文献

Abstract

In an era of globalization where the migration of long-term care workers is common, foreign live-in home care workers can compensate for the unavailability of family members and, perhaps, even substitute for institutional care in the provision of long-term care services to disabled older persons.

This study examines differences in home care satisfaction between disabled older persons in Israel with “live-in” home care workers and those with “live-out” workers, and explores some differences in socio-demographic and personal characteristics between these two groups. Face-to-face interviews were held with a random sample of 93 older persons in Beer-Sheva.

Older persons with live-in home care workers were more satisfied with their home care service than those with live-out workers. Those with live-in workers were more severely disabled, tended not to have any children living in close proximity, although an adult child was available as an informal caregiver. Communication difficulties between the elderly persons and their home care workers were found not to affect negatively the satisfaction with the service.  相似文献

ABSTRACT

The article tries to answer the question: Is elder abuse in residential care in Israel a myth or a reality? A broad definition of abuse was used, including the ‘classical’ forms presented in the literature, and also violation of rights and any act that infringes on quality of life of residents. As no data exist which directly explored this issue, the analysis was based on: recent laws mandating the report of abuse, governmental surveillance data, court cases, media clippings, and data from quality of life studies. Findings reveal that abuse in its ‘classical’ form exists only in a limited number of small private unlicensed facilities. However, when using the broader definition, abuse is a reality in many settings, exercised mainly by nurses' aides.  相似文献

美国碳关税制度违反了WTO基本规则,包括:最惠国待遇原则、国民待遇原则及约束关税制度。然而要证明该制度最终违反WTO,关键在于进一步证明该制度不符合WTO一般例外条款。按照WTO的司法实践,碳关税制度可以被解释为维护人类、动物或植物生命或健康所必需的措施,也可以被解释为保护可用竭自然资源有关的措施,因此符合一般例外(b)款及(g)款。但是该制度的真实目的是保护美国竞争力,因此不符合序言的规定,在WTO中不具有合法性。  相似文献

In this paper we obtain several influence measures for the multivariate linear general model through the approach proposed by Muñoz-Pichardo et al. (1995), which is based on the concept of conditional bias. An interesting charasteristic of this approach is that it does not require any distributional hypothesis. Appling the obtained results to the multivariate regression model, we obtain some measures proposed by other authors. Nevertheless, on the results obtained in this paper, we emphasize two aspects. First, they provide a theoretical foundation for measures proposed by other authors for the mul¬tivariate regression model. Second, they can be applied to any linear model that can be formulated as a particular case of the multivariate linear general model. In particular, we carry out an application to the multivariate analysis of covariance.  相似文献

A theory of equivariant prediction is developed for predicting the population total in finite populations. Minimum risk equivariant predictors (MREP) are derived under the location, scale and locationscale superpopulation models. Under the general linear model, it is shown that the best(linear) unbiased predictor (B(L)UP) is an MREP.  相似文献
