Objective: Research has identified correlates (eg, drug use, risky sex, smoking) of using alcohol mixed with energy drinks (AMEDs). Few studies have investigated common mental health-related concerns (eg, depression, sleep). Participants: Alcohol-using college students (n = 380 never used AMEDs, n = 180 used AMEDs) were recruited in the study during the fall 2011 semester. Methods: The study examined demographics, substance use, depressive symptoms, and sleep problems in association with AMED use. Results: Multivariable logistic regression indicated that alcohol use severity (AOR = 1.24; 95% CI = 1.14+1.34), drug use severity (AOR = 1.20; 95% CI = 1.04–1.39), depressive symptoms (AOR = 1.06; 95% CI = 1.01–1.12), and smoking (AOR = 2.12; 95% CI = 1.22–3.68) were independently associated with AMED use; sleep problems were non-significant. Conclusions: Administrators may consider policies regarding energy drink availability on campus, and campus health personnel may increase screening and education surrounding AMED use to reduce risks among students.  相似文献

Spouses form the largest single category of migrant settlement in the UK, but research and policy making on marriage‐related migration to Britain provides incomplete coverage of the phenomenon, having been dominated by a focus on the South Asian populations that are among the largest groups of such migrants. By bringing together immigration statistics with information from academic and third‐sector sources, this article attempts to provide a more balanced and nuanced portrayal of patterns and practices of marriage‐related migration to the UK. In doing so, it reveals important nationality and gender differences in migration flows and considers how varying marriage practices, social and political contexts, and policies of both receiving and sending countries may work to influence marriage‐related migration streams. It also exposes the limitations and lacunae in existing research on this diverse form of migration, highlighting the danger that immigration policy made on the basis of partial evidence will produce unexpected consequences.  相似文献

This article presents a mathematical model for the Enterobacteriaceae count on the surface of broiler chicken during slaughter and how it may be affected by different processing technologies. The model is based on a model originally developed for Campylobacter and has been adapted for Enterobacteriaceae using a Bayesian updating approach and hitherto unpublished data gathered from German abattoirs. The slaughter process in the model consists of five stages: input, scalding, defeathering, evisceration, washing, and chilling. The impact of various processing technologies along the broiler processing line on the Enterobacteriaceae count on the carcasses’ surface has been determined from literature data. The model is implemented in the software R and equipped with a graphical user interface which allows interactively to choose among different processing technologies for each stage along the processing line. Based on the choice of processing technologies the model estimates the Enterobacteriaceae count on the surface of each broiler chicken at each stage of processing. This result is then compared to a so-called baseline model which simulates a processing line with a fixed set of processing technologies. The model calculations showed how even very effective removal of bacteria on the exterior of the carcass in a previous step will be undone by the cross-contamination with leaked feces, if feces contain high concentrations of bacteria.  相似文献

This paper offers a conceptually informed analysis of fostering and adoption social work and argues for more consistent inclusion of trans and non‐binary people. The conceptual framework through which we explore current policy and practice is set out to provide clarity about the ways in which we employ the concepts of trans, gender diversity, and cisgenderism (a prejudicial ideology). We employ the notion of cisgenderism as a critical lens through which to overview fostering and adoption social work within the context of trans inclusion. Focus is turned to the existing literature relevant to trans parenting, trans‐headed families, and the field of fostering and adopting. We highlight significant knowledge gaps in this regard. We then argue that if fostering and adoption social work is to embody inclusive practice with trans people, a new culture must be embedded to promote collaborative working, enhance knowledge, and improve service provision. The paper concludes by asserting that such an approach must be underpinned by an understanding, acceptance, and appreciation of people who identify as trans and/or as non‐binary.  相似文献

When do children, adolescents, and adults decide to punish fairness violations? Two studies with 9‐year‐old children, 13‐year‐old adolescents, and adults investigated whether the link between unfairness and punishment was mediated by negative emotional reactions (measured through galvanic skin responses and emotion ratings). Study 1 (N = 117) examined this question in the context of second‐party punishment, where the punisher is a direct victim of the violation. Study 2 (N = 119) assessed third‐party punishment, where the punisher is an observer, unaffected by the violation. In each study, participants were presented with seven distributions of points, which differed in how fairly the points were allocated between a proposer and receiver, and had to decide whether to punish these distributions. Although the unfairness of the distribution strongly influenced second‐ and third‐party punishment in all age groups, the mediating role of emotional appraisals (i.e., galvanic skin responses vs. emotion ratings) depended on whether or not the punisher was personally affected by the violation and age. Thus, negative emotions primarily motivate costly punishment when the punisher is affected by the violation or when an unaffected third‐party punisher takes the perspective of the victim of a violation, an ability that develops between childhood and adolescence.  相似文献

Researchers have shown that stigma is a fundamental determinant of behavior, well-being, and health for many marginalized groups, but sex workers are notably absent from their analyses. This article aims to fill the empirical research gap on sex workers by reviewing the mounting evidence of stigmatization attached to sex workers’ occupation, often referred to as “prostitution” or “whore” stigma. We give special attention to its negative effect on the working conditions, personal lives, and health of sex workers. The article first draws attention to the problem of terminology related to the subject area and makes the case for consideration of prostitution stigmatization as a fundamental cause of social inequality. We then examined the sources of prostitution stigma at macro, meso, and micro levels. The third section focuses on tactics sex workers employ to manage, reframe, or resist occupational stigma. We conclude with a call for more comparative studies of stigma related to sex work to contribute to the general stigma literature, as well as social policy and law reform.  相似文献

In industrialized countries musculoskeletal disorders (MSD) play an import role and are often responsible for almost one third of the total sick leave. The changes in the demographic profiles, i.e. aging work forces might even worsen this situation in the future. For a highly productive and sustainable use of human resources in production systems, ergonomics offers high potentials. In the recent years the authors have developed several ergonomic risk assessment tools, especially for the use in automotive industries. These methods may be used during the planning phases in the Tech Centers as well as during the production phase at shop floor level. The tools might also be used for a standardized communication in between the Tech Center and the plants to improve the effects of "lessons learned" for the design and layout of workstations and processes and the optimization of vehicle components. This paper describes suitable risk assessment tools as well as the integration of these tools into the vehicle development process. It introduces a comprehensive management approach for the integration of ergonomics into the management of production systems.  相似文献
