There is a growing body of evidence demonstrating that sexual activity is important to the quality of life of older adults, and that it can be influenced by physical, psychological, and social factors. However, older adults’ experiences of sexual difficulties remain relatively unexplored. This article draws on qualitative data collected as part of the English Longitudinal Study of Ageing (ELSA). Participants answered a Sexual Relationships and Activities Questionnaire (SRA-Q), which included an open comment box for further details, 1,084 (1/7) of which were completed. These data were analyzed using Template Analysis, and findings on the experiences of sexual difficulties are presented in this article. Sexual difficulties were contextualized within the couple relationship and could be detrimental to the relationship, particularly if the partner would not seek professional help. Participants reported that sexual difficulties could also have a negative impact on psychological well-being, described mainly as frustration, depression, and sadness. For some participants the supportive nature of their relationship buffered these impacts. Few had sought professional help; those who had reported helpful and unhelpful experiences. These findings add to the limited evidence base and have implications for health care in the context of global aging and a growing recognition of older adults’ sexual rights.  相似文献

This paper considers quantile regression for a wide class of time series models including autoregressive and moving average (ARMA) models with asymmetric generalized autoregressive conditional heteroscedasticity errors. The classical mean‐variance models are reinterpreted as conditional location‐scale models so that the quantile regression method can be naturally geared into the considered models. The consistency and asymptotic normality of the quantile regression estimator is established in location‐scale time series models under mild conditions. In the application of this result to ARMA‐generalized autoregressive conditional heteroscedasticity models, more primitive conditions are deduced to obtain the asymptotic properties. For illustration, a simulation study and a real data analysis are provided.  相似文献

We conducted two studies to investigate the item-order effect on life satisfaction judgments. In Study 1, Japanese and American participants completed various life-domain satisfaction items either before or after completing general life satisfaction items. American respondents weighed the best life domains more strongly than Japanese respondents, in particular when they answered domain satisfaction items before making life satisfaction judgments. Overall, Japanese tended to weigh the worst life domains more heavily when making life satisfaction judgments than Americans. We hypothesized that the Japanese patterns of life satisfaction judgments come from the chronic attention to others’ perspective. To examine this hypothesis in Study 2, Japanese participants were exposed to either the “other are not watching” or the “other are watching” manipulation. As expected, when Japanese participants were led to believe that “others are not watching,” they judged their overall life satisfaction based more heavily on the best life domains (like Americans in Study 1).  相似文献

BackgroundSevere perineal tears sustained during childbirth cause significant distress and morbidity amongst women. The objective of this study was to compare the use of straight scissors for cutting an episiotomy with the use of curved scissors, which are designed to curve away from the anal sphincter.MethodsWe used a single-centre, randomised feasibility trial. The intervention was the use of curved scissors. Women were recruited during a prenatal visit and randomised in the delivery suite, when it became clear that an episiotomy was required. The feasibility outcomes were the proportion of women able to be recruited, randomised and followed up. We also calculated the incidence of obstetric anal sphincter injury when either straight or curved scissors were used to cut an episiotomy. Other outcomes assessed were pain, length of hospital stay, perineal infection and perineal dehiscence.ResultsOf the 155 patients recruited in the prenatal period, only 20 (12.9%) were eventually randomised at birth. The main reasons for the high loss were that women either did not have a vaginal delivery (38, 24.5%), or they did not need an episiotomy (72, 46.5%). Rates of obstetric anal sphincter injury and other outcomes were similar between groups.DiscussionAnal sphincter injury during childbirth remains an important problem. Although the use of curved scissors provides a theoretical solution, we found that the high attrition rate made feasibility of conducting a suitably powered, randomised trial using the current design untenable. Alternative strategies have been suggested to make any future study more viable.  相似文献

Using a convenience sample of 318 undergraduate and graduate social work students (193 women and 125 men) from a public university in India, this study examined the differences between Indian social work students' perceptions toward the role of government in addressing social issues in India. Using Predictive Analytics Software (PASW) 18, several statistical procedures were conducted to analyze the relationship between social work students' demographic variables and their perceptions of the government's role in addressing social issues in India. The results indicated that older social work students were more likely to perceive that the government should ensure equal opportunities for citizens. Female social work students were more likely to perceive that the government should ensure housing for citizens. BSW students were more likely to perceive that the government should ensure employment of citizens. Macro social work students were more likely to perceive that the government should ensure equal opportunities, housing, food, employment, and health insurance for citizens. The findings of this study may help social work educational administrators and faculty in India to develop a curriculum that provides social work students with the opportunity to critically examine the complex relationship between age, gender, marital status, number of children, socioeconomic status, educational status, area of concentration, and the role of the government in addressing social issues. Doing so will prepare social work students and professionals to think and engage in a manner that will allow them to challenge and advocate for a change to the status quo.  相似文献

Integrating volunteers into social care is widely expected but rarely successful in practice. This paper discusses how the Community Care Centre Plan organising community volunteers to provide services to the elderly in Taiwan. This plan successfully integrated social workers and volunteers in a national system to offer service in local communities, showing a systemic practice of community care and a unique case of community-based and volunteer-based service. The purposes of this paper are to introduce the programme design and to understand how to integrate the mission of social workers and volunteers’ performance. The governmental policy and requirements, the role of social workers and the provision of voluntary community service which contributed to form the system were examined in this paper.  相似文献

两晋时期军府制度逐渐发展定型,并对以尚书制度为核心的国家政治体制产生重大影响,其表现为:在中央层面,加兵公常领录尚书事,或兼领尚书令;地方镇将常兼领尚书省长官。这样,在国家政治生活中就出现了军府制断尚书事,甚至在非常时期成为替代尚书省的“国务总汇”机构,以及军府掾属权过尚书干涉政务等等不正常的现象。这些现象的产生,在一定程度上表明了两晋时期国家政治体制的孱弱。  相似文献
