ABSTRACT The literature on male-to-female transgender myriad problems such individuals face in their day-to-day lives, including high rates of HIV/AIDS, addiction to drugs, violence, and lack of health care. These problems are exacerbated for ethnic and racial minority MTFs. Support available from their social networks can help MTFs alleviate these problems. This article explores how minority MTFs, specifically in an urban environment, develop supportive social networks defined by their gender and sexual identities. Using principles of community-based participatory research (CBPR), 20 African American and Latina MTFs were recruited at a community-based health care clinic. Their ages ranged from 18 to 53. Data were coded and analyzed following standard procedure for content analysis. The qualitative interviews revealed that participants formed their gender and sexual identities over time, developed gender-focused social networks based in the clinic from which they receive services, and engaged in social capital building and political action. Implications for using CBPR in research with MTFs are discussed. 相似文献

In 1998, the research unit of the French Ministère de l'Emploi et de la Solidarité (MIRE) published a bilingual glossary of French and English terms used in social policy. A number of issues, questions and hypotheses, all related to translation and transferability, were raised in the course of this exercise. This article purports to take some of them up again. Although the glossary was a collective venture, the following interpretations are under the sole responsibility of the author. 相似文献

Websites containing information and advice about health are increasingly common and popular. It is important to understand whether the material these sites contain can positively influence individual behavior, and whether populations differ in their response to that material. Participants in an international web-based stop smoking randomized controlled trial (RCT) were screened for major depression; participants whose history and/or depression symptoms were deemed of concern were offered one of two prompts (Strong and Mild) to seek treatment, depending on depression history. Participants from 3 predominantly English-speaking and 3 predominantly Spanish-speaking countries were analyzed. Individuals given a Strong prompt were more likely to seek treatment for depression than those given a weak prompt (16.6% vs. 10.2% of previously untreated individuals reported seeking treatment), controlling for symptom level and other variables. Country-specific differences were observed, with participants from South Africa and Spain departing from the common pattern of Strong prompt leading to higher likelihood of treatment seeking. Older age and female gender, but not symptom level predicted higher likelihood of seeking treatment following a prompt. The results suggest that information provided by the health websites can promote help seeking in affected individuals. 相似文献

AbstractRachel Fleming and Kristin Calvert of Western Carolina University discuss their study of interlibrary loan borrowing requests in the three years surrounding a journal cancellation project. Noting that the impact of such a cancellation on interlibrary loan has not been studied since the 1990s, they examine numerous facets of requests for cancelled and non-cancelled journals, including request per journal, year of article requested, and request history for newly cancelled journals. Though journal cancellations resulted in a 2 percent increase in interlibrary loan requests, this number proved so small that Calvert and Fleming judged that their cancellations caused no undue effects. 相似文献

This article is devoted to the study of tail index estimation based on i.i.d. multivariate observations, drawn from a standard heavy-tailed distribution, that is, of which Pareto-like marginals share the same tail index. A multivariate central limit theorem for a random vector, whose components correspond to (possibly dependent) Hill estimators of the common tail index α, is established under mild conditions. We introduce the concept of (standard) heavy-tailed random vector of tail index α and show how this limit result can be used in order to build an estimator of α with small asymptotic mean squared error, through a proper convex linear combination of the coordinates. Beyond asymptotic results, simulation experiments illustrating the relevance of the approach promoted are also presented. 相似文献

We model the probabilities that a soccer team gets a target, for example, to play the Champions League, the UEFA Europa League or preserve the category. Taking into account the points won until de mth matchday of the competition, when the winter transfer window is closed. We give closed-form expressions for the probabilities of reaching the goals. We also introduce a risk measure which is going to give us the smallest initial points needed to ensure that the probability of getting the target is larger than a given level. 相似文献

It is often critical to accurately model the upper tail behaviour of a random process. Nonparametric density estimation methods are commonly implemented as exploratory data analysis techniques for this purpose and can avoid model specification biases implied by using parametric estimators. In particular, kernel-based estimators place minimal assumptions on the data, and provide improved visualisation over scatterplots and histograms. However kernel density estimators can perform poorly when estimating tail behaviour above a threshold, and can over-emphasise bumps in the density for heavy tailed data. We develop a transformation kernel density estimator which is able to handle heavy tailed and bounded data, and is robust to threshold choice. We derive closed form expressions for its asymptotic bias and variance, which demonstrate its good performance in the tail region. Finite sample performance is illustrated in numerical studies, and in an expanded analysis of the performance of global climate models. 相似文献

Test statistics for checking the independence between the innovations of several time series are developed. The time series models considered allow for general specifications for the conditional mean and variance functions that could depend on common explanatory variables. In testing for independence between more than two time series, checking pairwise independence does not lead to consistent procedures. Thus a finite family of empirical processes relying on multivariate lagged residuals are constructed, and we derive their asymptotic distributions. In order to obtain simple asymptotic covariance structures, Möbius transformations of the empirical processes are studied, and simplifications occur. Under the null hypothesis of independence, we show that these transformed processes are asymptotically Gaussian, independent, and with tractable covariance functions not depending on the estimated parameters. Various procedures are discussed, including Cramér–von Mises test statistics and tests based on non‐parametric measures. The ranks of the residuals are considered in the new methods, giving test statistics which are asymptotically margin‐free. Generalized cross‐correlations are introduced, extending the concept of cross‐correlation to an arbitrary number of time series; portmanteau procedures based on them are discussed. In order to detect the dependence visually, graphical devices are proposed. Simulations are conducted to explore the finite sample properties of the methodology, which is found to be powerful against various types of alternatives when the independence is tested between two and three time series. An application is considered, using the daily log‐returns of Apple, Intel and Hewlett‐Packard traded on the Nasdaq financial market.
