ABSTRACTProfessional ethics compel social workers to address all forms of discrimination and oppression. Microaggressions can contribute to health disparities for marginalized groups; yet, little is known about the frequency, mechanisms, and impact of microaggressions on sexual minorities, cisgender women, and gender minorities—particularly for those with intersecting marginalized identities. This article extends microaggression literature by exploring interrelated constructs of sexual orientation, gender, and gender identity microaggressions, and offering recommendations for future research using an intersectional lens to foster an integrated and complex understanding of microaggressions. Implications of an intersectional microaggression framework for social work education and practice are discussed. 相似文献

Satirical television news programs provide the public with potential sources of information about climate change. This study uses a segment from Last Week Tonight with John Oliver as a test case for exploring how coverage from such programs that features consensus messaging may influence viewers’ perceptions of global warming. The segment presents a “statistically representative climate change debate” to affirm the scientific consensus on anthropogenic climate change and satirize television news coverage “balancing” this consensus with skeptics’ arguments. Results from a randomized experiment demonstrate that watching the segment increased viewers’ own belief in global warming, as well as viewers’ perceptions that most scientists believe in global warming. The latter effect was stronger among participants with low interest in the environment and global warming than among those with high interest. The segment’s impact on perceptions of scientists’ views may have mediated its effects on viewers’ own beliefs about global warming. 相似文献

The present study examines the struggle for hegemony in the public sphere by two different systems, following Hong Kong’s handover to China in 1997. It has been postulated that the new media, particularly social media, has become an important public sphere for the citizens of Hong Kong to engage in an anti-hegemonic struggle against China’s discursive encroachment into Hong Kong since 1997. Given that the public platform provided by legacy media has been bought out or coopted by China, new media has begun to serve as a subaltern public sphere to enable resisting the hegemony imposed by China. This was analyzed through a survey conducted as part of this study, which showed that people who are young, read the Apple Daily, have high expectations of local autonomy, and a high regard for press freedom are prone to using social media to obtain their social and political information. This article analyzes the implications of the emergence of a counter-China hegemonic public sphere. 相似文献

It has been more than 25 years since the Americans with Disabilities Act (ADA) was passed by Congress. Many supporters of the law hoped that it would improve the employment outcomes for people with a disability, yet many scholars argue that it has fallen short in achieving this goal. Such judgments of success or failure are typically offered with little regard for the complex relationship between law and social change. In this paper, I apply a socio‐legal perspective to scholarly research regarding the impact of the ADA on employment. Socio‐legal studies offer a variety of concepts and perspectives, which better capture the complexity of law's impact on social life, and the various paths through which it might have an impact on social change. From this perspective, studies tend to assume that ADA law will either impact social change directly or indirectly. I discuss the findings of both of these approaches and conclude with some directions for future research. 相似文献

In this article, we introduce a new form of distribution whose components have the Poisson or Skellam marginal distributions. This new specification allows the incorporation of relevant information on the nature of the correlations between every component. In addition, we present some properties of this distribution. Unlike the multivariate Poisson distribution, it can handle variables with positive and negative correlations. It should be noted that we are only interested in modeling covariances of order 2, which means between all pairs of variables. Some simulations are presented to illustrate the estimation methods. Finally, an application of soccer teams data will highlight the relationship between number of points per season and the goal differential by some covariates. 相似文献

We show that the mean-model parameter is always orthogonal to the error distribution in generalized linear models. Thus, the maximum likelihood estimator of the mean-model parameter will be asymptotically efficient regardless of whether the error distribution is known completely, known up to a finite vector of parameters, or left completely unspecified, in which case the likelihood is taken to be an appropriate semiparametric likelihood. Moreover, the maximum likelihood estimator of the mean-model parameter will be asymptotically independent of the maximum likelihood estimator of the error distribution. This generalizes some well-known results for the special cases of normal, gamma, and multinomial regression models, and, perhaps more interestingly, suggests that asymptotically efficient estimation and inferences can always be obtained if the error distribution is non parametrically estimated along with the mean. In contrast, estimation and inferences using misspecified error distributions or variance functions are generally not efficient. 相似文献

In this paper, we propose novel methods of quantifying expert opinion about prior distributions for multinomial models. Two different multivariate priors are elicited using median and quartile assessments of the multinomial probabilities. First, we start by eliciting a univariate beta distribution for the probability of each category. Then we elicit the hyperparameters of the Dirichlet distribution, as a tractable conjugate prior, from those of the univariate betas through various forms of reconciliation using least-squares techniques. However, a multivariate copula function will give a more flexible correlation structure between multinomial parameters if it is used as their multivariate prior distribution. So, second, we use beta marginal distributions to construct a Gaussian copula as a multivariate normal distribution function that binds these marginals and expresses the dependence structure between them. The proposed method elicits a positive-definite correlation matrix of this Gaussian copula. The two proposed methods are designed to be used through interactive graphical software written in Java. 相似文献

Despite the tremendous research studying the factors that influence employees’ well-being, the effect of what happens when leisure time is spent with colleagues remains yet unexamined. Building on the Conversation of Resource Theory, we propose that leisure time spent with colleagues could be understood as a resource, especially for those individuals who have few friends at their workplace. In a cross-sectional design, 136 university employees provided information about the number of friends they have at work, the amount of leisure time spent with befriended colleagues, and their life satisfaction. Results suggest that a larger network of friends at work is positively associated with life satisfaction. Furthermore, the effect of the number of friends at work on life satisfaction is moderated by the amount of leisure time spent with befriended colleagues. Employees who have few friends at work report more life satisfaction, if they spend more leisure time with befriended colleagues, whereas such an effect was not found for employees with a large friend network at work. These results are placed into the context of current discussions about work-life-blending. 相似文献

Objectives: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods: Following ethnographic mapping of sex work venues, the authors revisited randomly selected venues to survey MSWs, TSWs and their clients. Results: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention. 相似文献
