This speculative essay examines ‘invisible’ social identities and the processes by which they are manifested and occasionally sought. Using various literary and academic sources, and loosely informed by an unlikely combination of Stoic philosophy and post-structuralist politics, we argue that invisibility is conventionally viewed as undesirable or ‘suffered’ by individuals or groups that are disadvantaged or marginalised within society. Whilst appreciating this possibility, we argue that social invisibility can also be the result of strategies carefully conceived and consciously pursued. We suggest that forms of social invisibility can be acquired by ethically informed personal action as well as by politically informed collective action. In this context, invisibility can be seen as a strategy of escaping from institutionalised and organisational judgements and which presents a challenge to common notions of voice and identity. 相似文献

Little data exist about the mental health needs of gay and bisexual men. This is due to limitations of existing studies such as small and nonrepresentative samples, failure to assess sexual orientation, and concerns about stigmatization, possibly causing sexual minority individuals to be reluctant to disclose their sexual orientation to researchers. Fenway Community Health is a large urban health center that serves the LGBT community. The large number of gay and bisexual men who present for mental health treatment allows for a unique opportunity to gain insight into mental health, prevention, and intervention needs for this group. The current study is a review of the mental health information from all of the gay and bisexual men who reported that they were HIV-negative during their mental health intake over a six-month period at Fenway Community Health (January to June 2000; N = 92). The most frequent presenting problems were depression, anxiety, and relationship issues. Additionally, presenting problems included current or past abuse, substance abuse, finance and employment, recent loss, and family issues. The most frequent diagnoses were depression, anxiety disorders, and adjustment disorders. These findings support the notion that presenting problems and mental health concerns among gay and bisexual men are similar to those frequently reported by individuals in other mental health facilities, however, specific psychosocial stressors are unique to this population. 相似文献

The authors investigated how low‐income young adults without children understand marriage and fertility. Data come from the Becoming Partners and Parents Study (N = 69), a qualitative study of African American adults aged 18 to 22 in a mid‐size southern city. This is the first study to analyze young, low‐income, childless, and unmarried Black respondents' frameworks (i.e., internal understandings of the world) of marriage and fertility. In contrast to research conducted on parents, this research on childless adults indicated a narrative in which there were close connections between marriage and fertility and an economic bar adhered to both marriage and childbearing. Respondents also believed that childbearing was meaningful and provided purpose, but that it was morally questionable if the parent was not financially stable. The results suggest that prior findings related to meanings of family formation and childbearing for low‐income parents may not extend to those without children. 相似文献

I collect data on how subjects acquire information about risky choices in both real and hypothetical settings using process‐tracing software called Mouselab. On average, there are no significant differences across settings in the amount of time subjects take to make a choice or the completeness of the information they acquire. Subjects also acquire information in sequences consistent with an integration model of decision‐making, such as expected utility theory or prospect theory. I do not find significant differences in risk preferences across settings, on average, but I do find that subjects' risk preferences are related to the completeness of the information that they acquire and where they start their information acquisition.

Recent research suggests that high-stakes standardized testing has played a negative role in the segregation of children by race and class in schools. In this article we review research on the overall effects of segregation, the positive and negative aspects of how desegregation plans were carried out following the 1954 Supreme Court decision Brown v. Board of Education, and the de facto re-segregation that followed the dismantling of many desegregation plans, along with the increase of school choice plans. We then analyze these effects in light of the ways that high-stakes standardized testing has grown in importance and intensity in US education policy and practice, especially during the most recent period of school re-segregation. Based on the evidence we argue that the intrinsic features of high-stakes testing, combined with current systems of school choice, function as mechanisms used for racial coding that facilitate segregation and compound inequalities found in schools. 相似文献

Reliable estimation of long-range dependence parameters is vital in time series. For example, in environmental and climate science such estimation is often key to understanding climate dynamics, variability and often prediction. The challenge of data collection in such disciplines means that, in practice, the sampling pattern is either irregular or blighted by missing observations. Unfortunately, virtually all existing Hurst parameter estimation methods assume regularly sampled time series and require modification to cope with irregularity or missing data. However, such interventions come at the price of inducing higher estimator bias and variation, often worryingly ignored. This article proposes a new Hurst exponent estimation method which naturally copes with data sampling irregularity. The new method is based on a multiscale lifting transform exploiting its ability to produce wavelet-like coefficients on irregular data and, simultaneously, to effect a necessary powerful decorrelation of those coefficients. Simulations show that our method is accurate and effective, performing well against competitors even in regular data settings. Armed with this evidence our method sheds new light on long-memory intensity results in environmental and climate science applications, sometimes suggesting that different scientific conclusions may need to be drawn. 相似文献

Competing risk methods are time‐to‐event analyses that account for fatal and/or nonfatal events that may potentially alter or prevent a subject from experiencing the primary endpoint. Competing risk methods may provide a more accurate and less biased estimate of the incidence of an outcome but are rarely applied in cardiology trials. APEX investigated the efficacy of extended‐duration betrixaban versus standard‐duration enoxaparin to prevent a composite of symptomatic deep‐vein thrombosis (proximal or distal), nonfatal pulmonary embolism, or venous thromboembolism (VTE)–related death in acute medically ill patients (n = 7513). The aim of the current analysis was to determine the efficacy of betrixaban vs standard‐duration enoxaparin accounting for non‐VTE–related deaths using the Fine and Gray method for competing risks. The proportion of non‐VTE–related death was similar in both the betrixaban (133, 3.6%) and enoxaparin (136, 3.7%) arms, P = .85. Both the traditional Kaplan‐Meier method and the Fine and Gray method accounting for non‐VTE–related death as a competing risk showed equal reduction of VTE events when comparing betrixaban to enoxaparin (HR/SHR = 0.65, 95% 0.42‐0.99, P = 0.046). Due to the similar proportion of non‐VTE–related deaths in both treatment arms and the use of a univariate model, the Fine and Gray method provided identical results to the traditional Cox model. Using the Fine and Gray method in addition to the traditional Cox proportional hazards method can indicate whether the presence of a competing risk, which is dependent of the outcome, altered the risk estimate. 相似文献

This article uses longitudinal data to estimate the short‐ and medium‐term economic effects of divorce in the USA, the UK, Switzerland, Korea, Germany and Australia during the first decade of the 21st century. Based on the data collected during the 2000s, in all of the countries studied, divorce had, on average, negative effects on the equivalised household incomes of women. However, the extent and duration of the negative effects of divorce differed markedly between countries. In all of the countries, the effects of divorce on the equivalised household income of men were smaller than for women. Although, using the available data, it is not possible to definitely explain the differences between countries, the analysis presented in this article has demonstrated that the average economic effects of divorce, particularly for women, are heavily influenced by the social security system, the labour market, family models and the family law system of each country. While the social security system and institutional arrangements such as child support and spousal maintenance do influence women's post‐divorce economic outcomes, what is most important in explaining cross‐country differences is women's labour market earnings and the extent to which re‐partnering occurs. 相似文献
