In the societal debate surrounding voluntary euthanasia or physician‐assisted suicide, there is a concern that older people will be left exposed to any legislation, subject to either faint suggestion or outright coercion from familial or professional carers. Whilst it is critical to take account of older people's potential vulnerability to any current or proposed assisted suicide legislation, there is a parallel strand of research exploring another relationship which older people can have with this debate: one of activism. Sociological research has shown that older people make up the “rank and file” of those active within the right‐to‐die movement. One of the stated motivations of some older people requesting hastened death has been that, in spite of an absence of life‐threatening disease, they feel “tired of life” or that they have lived a “completed life” and feel ready to die. The notion of suicide for reasons of longevity and being tired of life are becoming increasingly significant given the fact of global ageing. This article brings together empirical and theoretical research on the phenomenon of old age rational suicide in order to develop an underexplored area in both the sociology of death and the sociology of ageing. 相似文献

Weighted distributions (univariate and bivariate) have received widespread attention over the last two decades because of their flexibility for analyzing skewed data. In this article, we propose an alternative method to construct a new family of bivariate and multivariate weighted distributions. For illustrative purposes, some examples of the proposed method are presented. Several structural properties of the bivariate weighted distributions including marginal distributions together with distributions of the minimum and maximum, evaluation of the reliability parameter, and verification of total positivity of order two are also presented. In addition, we provide some multivariate extensions of the proposed models. A real-life data set is used to show the applicability of these bivariate weighted distributions. 相似文献

In this article we discuss various strategies for constructing bivariate Kumaraswamy distributions. As alternatives to the Nadarajah et al. (2011) bivariate model, four different models are introduced utilizing a conditional specification approach, a conditional survival function approach, and an Arnold–Ng bivariate beta distribution construction approach. Distributional properties for such bivariate distributions are investigated. Parameter estimation strategies for the models are discussed, as are the consequences of fitting two of the models to a particular data set involving the proportion of foggy days at two different airports in Colombia. 相似文献

The paper entitled “Bivariate and Multivariate Normal Characterizations: A Brief Survey,” by Hamedani, which was published in 1992, covered the published characterizations of bivariate and multivariate normal (MVN) distributions from 1941 to 1991. The present work is a follow-up to the 1991/1992 survey which includes not only characterizations of the bivariate and MVN distributions, but also characterizations of the matrix variate normal distribution, which have appeared from 1991/1992 to the present. 相似文献

This paper presents ideas about community change for diversedemocracy. It provides perspectives on change, identifies threetypes of practice, and examines some of its elements. It drawsupon secondary literature and empirical studies of practicein various communities and concludes with observations aboutfuture work in the field, with the general conclusion that democraticsocieties, especially ones whose populations are becoming morediverse, will depend in part on their ability to both recognizedifferences and also build bridges across cultural boundaries.The paper is based on the belief that strengthening the studyof these phenomena can contribute to their practice. 相似文献

Effective recruitment is a prerequisite for successful execution of a clinical trial. ALLHAT, a large hypertension treatment trial (N = 42,418), provided an opportunity to evaluate adaptive modeling of recruitment processes using conditional moving linear regression. Our statistical modeling of recruitment, comparing Brownian and fractional Brownian motion, indicates that fractional Brownian motion combined with moving linear regression is better than classic Brownian motion in terms of higher conditional probability of achieving a global recruitment goal in 4-week ahead projections. Further research is needed to evaluate how recruitment modeling can assist clinical trialists in planning and executing clinical trials. 相似文献

有许多众所周知的方法可以减少二氧化碳的排放,例如:减少石化燃料的使用、使用太阳能或风力等再生能源、开省油的车子或替代能源车、使用省电的电子产品,并切实做到减量、重复使用和回收等。然而,当前有关全球变暖的辩论几乎都集中在能源及交通运输方面。 相似文献

While researching the history of traditional child care institutions – children's homes, orphanages, industrial schools and reformatories – the author was impressed by the similarities of regimen across the spectrum of traditional care. Underpinning all forms of care was a severe discipline which often became abusive. Sexual abuse was also reasonably common. There were differences but it is the similarities which are stressed in this article, which seeks reasons for the perceived sameness. Children in care came mostly from the same deprived social background, and no matter what the intentions of the carers, traditional care involved a confrontation with cherished working class values which many of the children were bound to resist. Resistance was met by severe staff reaction; hence the violent undercurrent. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献
