Gay men living with HIV/AIDS face a complex of health issues, including those associated with the aging process, long-term HIV infection (25 years or more), and side effects from Highly Active Anti-Retroviral Therapy (HAART). If aging can increase marginalization, this is more likely for the aging HIV positive gay man, who is already marginalized for being queer and living with a stigmatizing disease. This article presents findings from a study of a long-running HIV support group. It locates the members, all gay men living with HIV, in a specific historical and political context to explore how feelings of loss and the struggle to sustain community affect long-term survivors and other older HIV+ gay men. We identify specific challenges presented by aging for men who contracted HIV early in the epidemic, contrasting them with those faced by men infected with the virus later in life. While both groups appear to struggle with a vision of what life could have been, had AIDS not forced loss and change, they also celebrate the community their shared plight has enabled. 相似文献

Samples of size n are drawn from a finite population on each of two occasions. On the first occasion a variate x is measured, and on the second a variate y. In estimating the population mean of y, the variance of the best linear unbiased combination of means for matched and unmatched samples is itself minimized, with respect to the sampling design on the second occasion, by a certain degree of matching. This optimal allocation depends on the population correlation coefficient, which previous authors have assumed known. We estimate the correlation from an initial matched sample, then an approximately optimal allocation is completed and an estimator formed which, under a bivariate normal superpopulation model, has model expected mean square error equal, apart from an error of order n-2, to the minimum enjoyed by any linear, unbiased estimator. 相似文献

We show the second-order relative accuracy, on bounded sets, of the Studentized bootstrap, exponentially tilted bootstrap and nonparametric likelihood tilted bootstrap, for means and smooth functions of means. We also consider the relative errors for larger deviations. Our method exploits certain connections between Edgeworth and saddlepoint approximations to simplify the computations. 相似文献

The difficulties associated with conducting valid family therapy research within a clinical practice discourage many potential researchers. This article will describe collaboration between a group of academics, researchers and clinicians who decided to explore the process and efficacy of systemic family therapy conducted within a working private practice. The specific questions we are addressing are, whether the requests clients bring to their first session of therapy can be reliably classified by practitioners, whether these requests change over time, and whether the nature of the request is associated with therapist and client ratings of therapeutic outcome. Additional questions about the form and nature of the therapeutic alliance as experienced by both client and practitioner are also being explored. This paper will map the passage of the work from inception to its current state where over 140 clients are active participants. In doing so attention will be paid to the obstacles encountered: practical, financial and ethical, and the solutions devised to address these. 相似文献

The paper gives the saddlepoint approximation for the distribution function of the sample quantile. A comparison of the saddlepoint approximations for the distribution functions of the sample quantile and the bootstrap quantile shows that the error of the bootstrap approximation to the distribution of the sample quantile obtained by Singh (1981) as an absolute error is actually a relative error. 相似文献

The Pushcart Prize, established in 1976, has a well-deserved reputation for highlighting the best in small press publication. The authors examined the first thirty volumes, 1976/1977 through 2006, to identify attributes of the items included in each volume and placed the volumes into five time periods of six volumes each to facilitate trend analysis. In order to identify the most productive publications, titles that had fewer than four selections in the thirty volumes and did not appear in at least two time periods were eliminated. The authors examined: press status as independent or affiliated, state and region where published, and type of work (poetry or other). Finally, highly productive titles were reviewed in WorldCat to determine how frequently these were held in the United States.California, Massachusetts, New York, and Ohio have a continuing, substantial presence in the Prize volumes. Most of the publications included were still active and were affiliated with a larger institution. The three small press titles appearing most frequently were Ploughshares, Paris Review, and American Poetry Review. The Pushcart Prize selections most frequently listed in WorldCat were the Hudson Review, the Paris Review, and the American Poetry Review. Each is held by more than eight hundred U.S. libraries. 相似文献

The goal of this study was to examine children's cognitive and language development and social engagement of mother as mediators of the relationship between maternal emotional availability at 15 months and children's empathy at the ages of two and four. Participants were 661 low-income, ethnically diverse mother-child dyads participating in a trial of home visitation in the Denver area. Using home- and lab-based free-play episodes, mothers' emotional availability (15 months) and children's social engagement of mother (21 and 24 months) were assessed. Standardized measures were used to assess children's language development (21 months) and cognitive development (24 months). Empathy was assessed using a simulated injury paradigm at ages two (both 21 and 24 months) and four. The predictive models supported the hypothesis that the child's cognitive and social resources mediate the relationship between maternal emotional availability and children's empathy with respect to empathy at the age of two toward both mothers and an unfamiliar examiner. These results indicate that parental sensitive behavior is not the only important condition for predicting children's empathy, and that children's own internalized resources are a likely mechanism of transmission from parents caring for their children to children learning to care for others. 相似文献

We develop a model to understand the incidence of presidential and parliamentary institutions. Our analysis is predicated on two ideas: first, that minorities are relatively powerful in a parliamentary system compared to a presidential system, and second, that presidents have more power with respect to their own coalition than prime ministers do. These assumptions imply that while presidentialism has separation of powers, it does not necessarily have more checks and balances than parliamentarism. We show that political leaders who prefer presidentialism may be supported by their own coalition if they fear losing agenda‐setting power to another group. We argue that the model is consistent with a great deal of qualitative information about presidentialism in Africa and Latin America. (JEL: D72, P5, O1) 相似文献

There has been a shift in the most recent UK Government's Alcohol Strategy (2012) from personal responsibility towards a model of shared responsibility for young people's drinking. On closer examination of the strategy, however, it appears that rather than exonerating young people from blame, governance is merely extended to include wider partners. Using findings from nine focus groups with young people in Liverpool, UK, we explore who they believe are responsible for their drinking behaviours and how they learn to become ‘good drinkers’. Our findings show that while teenagers were aware of dominant alcohol-related messages and maintained a moral position as responsible citizens; they also negotiated and resisted norms about teenage drinking. Although both boys and girls agreed that parents were the primary responsible authority for regulating their drinking, there was gendered disagreement about personal responsibility. The girls described how they were ultimately responsible for any adverse consequences if they drank too much whilst the boys considered a wide range of partners who would be implicated. However, unlike the girls, the boys described a willingness to either abstain or moderate their alcohol intake in order to remain in control and avoid any alcohol-related trouble or harm. 相似文献
