Using a symbolic interactionist approach, interviews of 10 Black single full-time fathers indicate that these fathers perceive parenting to have had positive results for themselves. Specifically, the employment and income of most of the men had remained stable or improved. While their dating lives had suffered the most, they had sustained social activities with friends and families at a high level. Moreover, their assessments of their parent-child relationships and their own life satisfaction was positive. 相似文献

Background
Centenarians are a growing population in Europe and present significant variability in motor and cognitive functions. The aim of our study was to characterize health status, as well as cognitive and motor functions in a group of Portuguese centenarians. In addition, our study also aimed at analyzing the relationship between cognitive functions and the burden of diseases affecting the elderly.Methods
Fifty-two centenarians were evaluated using the Mini-Mental State Examination, short version. Walking-related parameters (velocity and time spent in the 3 m walk test), grip strength and number of age-related illnesses were also measured. The relationship between cognitive scores and time spent in the three metre walk test, velocity, grip strength and number of diseases was analysed.Results
Cognitive scores showed a positive correlation with both handgrip strength and time spent in the three metre walk. In contrast, no association was found between cognitive scores and the presence/absence of disease, walking velocity or number of diseases present.Conclusions
These results suggest that in centenarians, cognitive functions may be related with motor functions.3.

This paper considers equilibrium quit turnover in a frictional labor market with costly hiring by firms, where large firms employ many workers and face both aggregate and firm specific productivity shocks. There is exogenous firm turnover as new (small) startups enter the market over time, while some existing firms fail and exit. Individual firm growth rates are disperse and evolve stochastically. The paper highlights how dynamic monopsony, where firms trade off lower wages against higher (endogenous) employee quit rates, yields excessive job‐to‐job quits. Such quits directly crowd out the reemployment prospects of the unemployed. With finite firm productivity states, stochastic equilibrium is fully tractable and can be computed using standard numerical techniques. 相似文献

Summary. A recent advance in the utility of extreme value techniques has been the characteri- zation of the extremal behaviour of Markov chains. This has enabled the application of extreme value models to series whose temporal dependence is Markovian, subject to a limitation that prevents switching between extremely high and extremely low levels. For many applications this is sufficient, but for others, most notably in the field of finance, it is common to find series in which successive values switch between high and low levels. We term such series Markov chains with tail switching potential, and the scope of this paper is to generalize the previous theory to enable the characterization of the extremal properties of series displaying this type of behaviour. In addition to theoretical developments, a modelling procedure is proposed. A simulation study is made to assess the utility of the model in inferring the extremal dependence structure of autoregressive conditional heteroscedastic processes, which fall within the tail switching Markov family, and generalized autoregressive conditional heteroscedastic processes which do not, being non-Markov in general. Finally, the procedure is applied to model extremal aspects of a financial index extracted from the New York Stock Exchange compendium. 相似文献

This paper explores the nature of engagement in the therapy process, and proposes that engagement may be facilitated when both client and therapist are able to develop an appreciation of each other's position within the therapeutic relationship. Some ways that a therapist can assist in this process are explored. An experiment is described in which information letters are sent to clients before the initial therapy session, as a possible way to enhance the engagement process. 相似文献

ABSTRACTThe current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review. 相似文献

Penalized likelihood inference in extreme value analyses 总被引:1,自引:0,他引:1
Models for extreme values are usually based on detailed asymptotic argument, for which strong ergodic assumptions such as stationarity, or prescribed perturbations from stationarity, are required. In most applications of extreme value modelling such assumptions are not satisfied, but the type of departure from stationarity is either unknown or complex, making asymptotic calculations unfeasible. This has led to various approaches in which standard extreme value models are used as building blocks for conditional or local behaviour of processes, with more general statistical techniques being used at the modelling stage to handle the non-stationarity. This paper presents another approach in this direction based on penalized likelihood. There are some advantages to this particular approach: the method has a simple interpretation; computations for estimation are relatively straightforward using standard algorithms; and a simple reinterpretation of the model enables broader inferences, such as confidence intervals, to be obtained using MCMC methodology. Methodological details together with applications to both athletics and environmental data are given. 相似文献

There is sometimes a perception in the counselling field that work in the area of disability is qualitatively different from all other work. Counsellors can easily disqualify themselves from thinking they have anything to offer when disability is present. This paper highlights the effects and limitations of the sort of thinking which defines clients according to their membership of a particular clinical population, and challenges counsellors to consider what they have to offer in this area. The paper describes the utilisation of a solution focused framework with families who have a child or adolescent with a disability. Some examples of the use of the ‘miracle’ question are described, with a consideration of dilemmas raised where disabilities are long term and unchanging. 相似文献

Undertaking interview‐based research with victim/survivors of child abuse can be difficult and challenging for researchers. Much has been written about the impact of research on participants, but researcher effects are less explored. This paper reviews the literature on sensitive interview‐based research and child abuse research. The theoretical underpinnings of researcher trauma are outlined and challenges identified and related to child abuse research using researcher reflections from the authors' interview‐based research with children who have been abused and young mothers who were sexually abused in childhood. Strategies and recommendations are developed to minimise child abuse researcher trauma. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
