Little is known about the experiences of lesbian, gay, bisexual, and transgender (LGBT) physicians in the workplace. There is little formal education in medical school about LGBT issues, and some heterosexual physicians have negative attitudes about caring for LGBT patients or working with LGBT coworkers, setting the stage for an exclusive and unwelcoming workplace. The current study used an online survey to assess a convenience sample of 427 LGBT physicians from a database of a national LGBT healthcare organization, as well as a snowball sample generated from the members of the database. Although rates of discriminatory behaviors had decreased since earlier reports, 10% reported that they were denied referrals from heterosexual colleagues, 15% had been harassed by a colleague, 22% had been socially ostracized, 65% had heard derogatory comments about LGBT individuals, 34% had witnessed discriminatory care of an LGBT patient, 36% had witnessed disrespect toward an LGBT patient's partner, and 27% had witnessed discriminatory treatment of an LGBT coworker. Few had received any formal education on LGBT issues in medical school or residency. It appears that medical schools and health care workplaces continue to ignore LGBT issues and operate in discriminatory fashion far too often.  相似文献

New Zealand (NZ) Europeans show a unique implicit bicultural effect, with research using the Implicit Association Test consistently showing that they associate Māori (the Indigenous peoples) and their own (dominant/advantaged majority) group as equally representative of the nation. We replicated and extended this NZ = bicultural effect in a small online national sample of Māori and NZ Europeans. The NZ European majority showed a consistent NZ = bicultural effect. Māori, in contrast, showed an automatic ingroup NZ = Māori effect. These results are contrary to predictions derived from Social Identity Theory and System Justification Theory, and instead seem more consistent with a model incorporating the pervasive effects of culture-specific symbols on automatic representations of the national category.  相似文献

To efficiently and completely correct for selection bias in adaptive two-stage trials, uniformly minimum variance conditionally unbiased estimators (UMVCUEs) have been derived for trial designs with normally distributed data. However, a common assumption is that the variances are known exactly, which is unlikely to be the case in practice. We extend the work of Cohen and Sackrowitz (Statistics & Probability Letters, 8(3):273-278, 1989), who proposed an UMVCUE for the best performing candidate in the normal setting with a common unknown variance. Our extension allows for multiple selected candidates, as well as unequal stage one and two sample sizes.  相似文献

This paper argues for a renewed research agenda on the transnational mobility of young people across both youth studies and migration studies. We review key literature across these fields, before arguing for a new conceptual framework that helps to further extend the emerging interdisciplinary space of ‘youth mobility studies’ (Raffaetà, Baldassar and Harris 2016). Our central proposition is that mobility has become an important marker and maker of transitions for youth in many contexts globally. We argue that a conceptual advance is required to understand the unique circumstances of a generation ‘on the move’ as they navigate diverse and non-sequential social, civic and economic practices of ‘adulthood’, and propose the conceptual framework of mobile transitions as a timely new agenda. ‘Mobile transitions’ describes transition pathways under conditions of mobility but also emphasises two key claims around the further development of transnational youth mobility research. The first is the importance of an orientation towards spatio-temporal complexity, multiplicity and fragmentation of both ‘youth transition’ and ‘migrancy’ as scholarly concepts and lived experiences. The second is an argument for understanding ‘mobile transitions’ in relation to three intersecting domains – economic opportunities, social relations and civic practices – rather than through linear notions of the achievement of economic and social autonomy.  相似文献

There are many definitions of new ways of work, but working with a computer at another location than at the office or at the clients' location with Information Communication Technology as a support is becoming more prevalent. A new office having shared desks and facilitating informal meetings along with a changed leadership style is yet another way. Examining the experiences of alternative work styles, telework, between the Netherlands and the USA are especially apparent in the design of office environments as is the emergence of new leadership behaviors to promote safe and healthy work.  相似文献

With the rising number of teleworkers who are working in non-traditional work locations, health and safety issues are even more critical. While telework offers attractive alternatives to traditional work locations, it is not without challenges for employers and workers. A macroergonomics approach or work system design for telework programs is proposed to address these new challenges. This approach explains the impact of organizational, psychosocial and workplace risk factors on teleworker's health and safety. A process for managing the health and safety of teleworkers is presented along with preventive strategies to provide an injury-free working environment.  相似文献

This paper extends our previous discussion on embodied heterosexual masculinities, men’s emotional lives and health ( Monaghan and Robertson 2012 ). First, we foreground writings on men’s health within and outside of heterosexual relationships given the interrelations between masculinities and other structures (e.g. the political economy). Second, we critically consider writings on masculinities, male bodies and emotions in a relational context. In conclusion, we underscore the need for future research. Such research would foreground men’s corporeal meanings, practices and relations while also critiquing global neoliberalisation, a pernicious process that impacts everyday lives within and beyond heterosexual configurations of body‐reflexive practice.  相似文献

In this paper, we extend the use of assurance for a single study to explore how meeting a study's pre-defined success criteria could update our beliefs about the true treatment effect and impact the assurance of subsequent studies. This concept of conditional assurance, the assurance of a subsequent study conditional on success in an initial study, can be used assess the de-risking potential of the study requiring immediate investment, to ensure it provides value within the overall development plan. If the planned study does not discharge sufficient later phase risk, alternative designs and/or success criteria should be explored. By transparently laying out the different design options and the risks associated, this allows for decision makers to make quantitative investment choices based on their risk tolerance levels and potential return on investment. This paper lays out the derivation of conditional assurance, discusses how changing the design of a planned study will impact the conditional assurance of a future study, as well as presenting a simple illustrative example of how this methodology could be used to transparently compare development plans to aid decision making within an organisation.  相似文献

Quality of life (QoL) was an important endpoint in the adjuvant breast cancer trials International Breast Cancer Study Group (IBCSG) Trial VI and VII. Here, QoL was considered as a time-dependent effect. The hypothesis explored is that poorer QoL throughout the trial is associated with poorer disease-free survival (DFS) and vice-versa. Potential bias in the parameter estimates is an important concern associated with missing observations. Standard simple and multiple imputation methods were applied to missing QoL assessments before analysis in a time-dependent Cox model. There was no evidence that the patient's QoL is related to the patient's DFS.  相似文献

Within risk analysis and, more broadly, the decision behind the choice of which modeling technique to use to study the spread of disease, epidemics, fires, technology, rumors, or, more generally, spatial dynamics, is not well documented. While individual models are well defined and the modeling techniques are well understood by practitioners, there is little deliberate choice made as to the type of model to be used, with modelers using techniques that are well accepted in the field, sometimes with little thought as to whether alternative modeling techniques could or should be used. In this article, we divide modeling techniques for spatial transmission into four main categories: population‐level models, where a macro‐level estimate of the infected population is required; cellular models, where the transmission takes place between connected domains, but is restricted to a fixed topology of neighboring cells; network models, where host‐to‐host transmission routes are modeled, either as planar spatial graphs or where shortcuts can take place as in social networks; and, finally, agent‐based models that model the local transmission between agents, either as host‐to‐host geographical contacts, or by modeling the movement of the disease vector, with dynamic movement of hosts and vectors possible, on a Euclidian space or a more complex space deformed by the existence of information about the topology of the landscape. We summarize these techniques by introducing a taxonomy classifying these modeling approaches. Finally, we present a framework for choosing the most appropriate spatial modeling method, highlighting the links between seemingly disparate methodologies, bearing in mind that the choice of technique rests with the subject expert.  相似文献
