Some extensions of Shannon entropy to the survival function have been recently proposed. Misagh et al. (2011) introduced weighted cumulative residual entropy (WCRE) that was studied more by Mirali et al. (2015). In this article, the dynamic version of WCRE is proposed. Some relationships of this measure with well-known reliability measures and ageing classes are studied and some characterization results for exponential and Rayleigh distributions are provided. Also, a non parametric estimation of dynamic version of WCRE is introduced and its asymptotic behavior is investigated. 相似文献

This article spells out the methodological considerations and various procedural and methodological subtleties developed over the author's quarter century of sociological field studies of Russia's peasant worlds. Particular attention is paid to “voices from below”—peasant discursive formats that capture, in natural and undiluted form, the evolution of peasant practices constituting the core of everyday life. In particular, the phenomenon of generational sorrow and a special chronological nostalgia that functions as a “social gyroscope” is identified and discursively captured. This phenomenon is noteworthy and useful for its ability to retain a record of the productively longed for past in a rural community's collective memory and thereby influence new peasant worlds taking shape today. 相似文献

The status quo of Roma communities in Europe is strongly marked by marginalisation and discrimination. Roma people tend to face social exclusion and segregation leading to lack of education, chronic unemployment and limited access to healthcare, housing and public services as well as widespread poverty. Very few studies have been conducted as far as Roma community in Cyprus are concerned and almost none has explored quality of life of this ethnic minority. Therefore, this article examines quality of life dimensions in approximately half of the population (n?=?156) residing in the catchment area. Both quantitative and qualitative results showed poor standards of living, high school dropout rates and high levels of marginalisation. Social work as discipline can foster a more empowering and coordinating role as to enhance Roma’s distinctive identity and improve standards of living. 相似文献

We study objective Bayesian inference for linear regression models with residual errors distributed according to the class of two-piece scale mixtures of normal distributions. These models allow for capturing departures from the usual assumption of normality of the errors in terms of heavy tails, asymmetry, and certain types of heteroscedasticity. We propose a general non-informative, scale-invariant, prior structure and provide sufficient conditions for the propriety of the posterior distribution of the model parameters, which cover cases when the response variables are censored. These results allow us to apply the proposed models in the context of survival analysis. This paper represents an extension to the Bayesian framework of the models proposed in [16]. We present a simulation study that shows good frequentist properties of the posterior credible intervals as well as point estimators associated to the proposed priors. We illustrate the performance of these models with real data in the context of survival analysis of cancer patients. 相似文献

This article considers statistical analysis of dependent competing risks model from Weibull distribution in accelerated life testing, in which copula function is used to examine the dependence structure between competing failure modes. We derive the maximum likelihood estimates, the approximate, and Bootstrap confidence intervals of the parameters. The effects of different dependence structures on the estimates of parameters are investigated. The simulation is given to compare the performance of the estimates when the competing failure modes are dependent with those when the failure modes are independent. Finally, one dataset was used for illustrative purpose in conclusion. 相似文献

In this cross-sectional study, we tested the relationship between sociophysical environment, quality of life (QOL), and perceived social support among elderly in Iran. The sample includes 128 participants recruited in the city of Shahrekord, Iran. We measured Evaluation of Older People Living Environment (EVOLVE); Control, Autonomy, Self-realization and Pleasure scale (CASP-19) and Multidimensional Scale of Perceived Social Support (MSPSS) tools respectively, through home-based observation and interview. A significant relationship was found between several domains of home environment, QOL, and perceived social support. The interaction effect of the home environment and gender in relation to QOL and perceived social support was statistically significant. Our results support that the home physical environment may not be considered a strong predictor of QOL among the Iranian elderly. 相似文献

The ‘digital glimpse’ as imagining home 总被引:2,自引:0,他引:2
This paper proposes the concept of the ‘digital glimpse’, which develops the existing framing of imaginative travel. Here it articulates the experiences of mobile workers digitally connecting into family life and everyday rituals when physically absent with work. The recent embedding of digital communication technologies into personal relationships and family life is reconfiguring how absence is experienced and practiced by workers on the move, and through this, new digital paradigms for life on-the-move are emerging. This paper explores how such social relationships are maintained at-a-distance through digital technology – using evidence from qualitative interviews with mobile workers and their families. Digital technology now enables expressive forms of ‘virtual travel’, including video calling, picture sharing, and instant messaging. This has implications for the ways in which families can manage the social and relational pressures of being apart. Experiences of imaginative travel created through novel media can enrich the experience and give a greater sense of connection for both those who are at home and those who are away. While technology is limited in its ability to replicate a sense of co-presence, ‘digital glimpses’ are an emergent set of sociotechnical practices that can reduce the negative impact of absence on family relationships. 相似文献

The literature on workers in gender atypical occupations has been dominated by a focus on women doing men’s work. Much less attention has been paid to men in women’s work, and even less to the impact of migration. Based on 28 in-depth interviews with migrant men having experiences of working in hands-on social care in England, this article is a contribution to the understanding of migrant men’s entry dynamics into a female-dominated occupation. Focusing on migrant life experiences, it discusses how they actively engage in three entry dynamics: (1) facing barriers and negotiating them, (2) ‘stumbling upon’ women’s work, then developing compensating strategies and (3) migratory/temporary settling into the sector. The article suggests a theory about lifelong ‘travelling’ when entering women’s work: a continuing process of negotiating work options within a specific historical sector context, the intersection of gender and migration being part of this. 相似文献

Previous research suggests that developments in young people's peer relationships may either compound or alleviate the adverse impacts of other major life changes during adolescence. We explored this proposition with respect to young people's educational attainment upon leaving high school, using longitudinal data from a large cohort of Australian secondary school students (n?=?1612) who have taken part in the Our Lives research study between the ages of 12/13 and 19/20 years. Our analysis focused on the role of peer relationship events such bullying, friendship problems, falling in love, and breaking up with someone. Bullying and romantic involvement were associated with lower odds of receiving a competitive tertiary entrance rank at the end of high school. However, close, resilient friendships – in which status and identity conflicts may be more easily tolerated and resolved – may help to offset the role of these other events. As well as reviewing the consequences of our findings for young people's educational and occupational trajectories in the longer-term, we highlight their implications for future research and policy in this area. 相似文献

Becoming alone in old age can be a decisive life event that brings major changes depending on various causes as health status, financial resources, family situation, and available welfare services. This article discusses the situation of older people in Sweden who have transitioned from a two-person to single-person household in recent years and what impact this might have on their everyday lives. Through in-depth interviews with 18 older people, age 67–90, their experiences about life conditions and opportunities were examined. Findings showed large differences between the men and women. They all tried to live as they always had done and they used the same personal life strategies that they always had. But the men could live as before on their own financial merits, while the women needed assistance from children, grandchildren and the welfare system. Transportation options were central and clearly related to both private economy and social services available. Shortcomings in the welfare state's way of caring for the elderly were clearly uncovered. The gap between social policy promises of opportunities for autonomy and independence to live an active life in old age and the everyday reality for older people still seems to be wide. 相似文献
