Disability at work: Understanding the impact of the ADA on the workplace

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.     

Some contributions on the multivariate Poisson–Skellam probability distribution

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.     

Orthogonality of the mean and error distribution in generalized linear models

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.     

Eliciting Dirichlet and Gaussian copula prior distributions for multinomial models

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.     

Let’s go out for a drink after work! The relation between leisure time spent with colleagues and employees’ life satisfaction

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.     

Sexual Risk,Behavior, and HIV Testing and Status Among Male and Transgender Women Sex Workers and Their Clients in Lima,Peru

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.     

Do perceptions of their partners’ childbearing desires affect young women’s pregnancy risk? Further study of ambivalence

We explore whether young women’s perceptions of their sexual partners’ childbearing desires contribute to their risk of pregnancy. We used weekly journal data collected from 787 young women to measure their childbearing desires and their perceptions of their partners’ childbearing desires. We then conducted hazard modelling to predict pregnancy risk with variables based on interactions between the women’s desires and their perceived partners’ desires. Models that include perceived partners’ desires perform better than one based on women’s desires alone. The best model contains three significant predictors: one confirms the importance of pronatal, ambivalent, and indifferent desires for pregnancy risk; one indicates that the perceived partners’ antinatal desires reduce women’s pregnancy risk; and one suggests that women who both perceive their partners accurately and are in agreement with them have a lower pregnancy risk. The results indicate that perceived partner data can improve prediction and enhance our understanding of pregnancy risk.     

Rejected by Family for Being Gay or Lesbian: Portrayals,Perceptions, and Resilience

A myriad of negative psychosocial outcomes face gay men and lesbians who experience rejection by their family for not being heterosexual. However, what constitutes rejection is not clear, and, more importantly, it is not known how resilience is fostered within such a context. This qualitative study sought to examine these issues by exploring the lived experiences of Australian gay men and lesbians who were previously or were currently experiencing family rejection because of their sexuality. A total of 21 in-depth, semistructured interviews were individually conducted and analyzed. Thematic analysis of the interviews revealed several themes that provided greater understanding of the portrayals and perceptions of family rejection; the impact of family rejection on mental health; and, importantly, how these individuals came to establish resilience in the face of experiencing family rejection. Limitations, directions for future research, and clinical implications of the findings are also discussed.     

Influence of Perceived Maternal Psychological Control on Academic Performance in Chinese Adolescents: Moderating Roles of Adolescents’ Age,Gender, and Filial Piety

Existing studies with East Asian samples have reported inconsistent findings on the association between parental psychological control and academic performance in children and adolescents. A moderation effect is present, when the magnitude or direction of the association between two variables significantly changes with another variable called a moderator. This study explored moderators for the association between maternal psychological control and academic performance. A total of 338 Chinese secondary school students aged 14–20completed self-report measures of perceived maternal psychological control, academic performance, and attitudes toward filial piety. Structural equation modeling suggested that adolescent age moderated the association of interest: the influence of perceived maternal psychological control on academic performance significantly varied between middle adolescents aged 14–17 and late adolescents aged 18–20. Based on the findings, this study offers a possible rationale for the inconsistent findings in studies with East Asian samples and proposes that parenting effect should be assessed developmentally.
