ABSTRACTThis study sheds new light on the role of identity in virtual environments when virtual representation of self is in support of disabled individuals and the potential impact of their virtual identity on work opportunities. It is widely understood that individuals who live with disability often experience a lifetime of bullying, exclusion, marginalization and rejection. They often experience workplace bias and discrimination. Yet, when they can create an identity and experience embodiment in virtual environments, the results can be extraordinarily powerful – even life-changing. This research builds on nearly a decade of ethnographic research in 3D online immersive social virtual worlds; seven of those years working with disability communities to answer the following: RQ1: In a virtual world where one can choose any avatar form, how does that visual sense of self-representation influence one’s ability to gain access to a social network, to be a leader in that network, and to find work? RQ2: How does realism in representation influence work experiences in these digital worlds? The results reveal the importance of choice in online representation of avatars in creating work and online social engagement. Implications contribute to our understanding of visual bias in the workplace and how emerging virtual reality technologies may open new avenues for meaningful work and social interactions for people with disabilities. 相似文献

The EPA Health Risk Assessment of Methylcyclopentadienyl Manganese Tricarbonyl (MMT) 总被引:1,自引:0,他引:1
This paper describes the U.S. Environmental Protection Agency's assessment of potential health risks associated with the possible widespread use of a manganese (Mn)-based fuel additive, methylcyclopentadienyl manganese tricarbonyl (MMT). This assessment was significant in several respects and may be instructive in identifying certain methodological issues of general relevance to risk assessment. A major feature of the inhalation health risk assessment was the derivation of Mn inhalation reference concentration (RfC) estimates using various statistical approaches, including benchmark dose and Bayesian analyses. The exposure assessment component used data from the Particle Total Exposure Assessment Methodology (PTEAM) study and other sources to estimate personal exposure levels of particulate Mn attributable to the permitted use of MMT in leaded gasoline in Riverside, CA, at the time of the PTEAM study; on this basis it was then possible to predict a distribution of possible future exposure levels associated with the use of MMT in all unleaded gasoline. Qualitative as well as quantitative aspects of the risk characterization are summarized, along with inherent uncertainties due to data limitations. 相似文献

In this paper we extend the ELSP model to allow for linearly changing demand rates over a fixed planning horizon. This extension of the ELSP research provides a model that can be used in coordinating the production and marketing planning activities in a firm. The model allows the user to evaluate the impact of changes in product demand on production costs and customer service. We solve the model using a standard nonlinear programming package (MINOS) and show through examples based on actual production data how the model can be used to support coordinated production and marketing planning. 相似文献

Virtual communities of practice are an international phenomenon in social work around the world. However, they are rare in social work in the United States. This article describes an online community, the Social Group Work Commons, designed to complement courses in social group work. Using Web 2.0 Internet tools, such as blogs, discussion boards, and chats, the developers employed group work skills to help students establish a vehicle for mutual support as students struggled to integrate course content in their field placements. Examples from course blogs indicate students became increasingly intimate in their online exchanges over time and readily provided each other support in applying course content in their practice. 相似文献

ObjectiveTo undertake a systematic review of the literature to determine whether Asian ethnicity is an independent risk factor for severe perineal trauma in childbirth.MethodOvid Medline, CINAHL, and Cochrane databases published in English were used to identify appropriate research articles from 2000 to 2010, using relevant terms in a variety of combinations. All articles included in this systematic review were assessed using the Critical Appraisal Skills Programme (CASP) ‘making sense of evidence’ tools.FindingsAsian ethnicity does not appear to be a risk factor for severe perineal trauma for women living in Asia. In contrast, studies conducted in some Western countries have identified Asian ethnicity as a risk factor for severe perineal trauma. It is unknown why (in some situations) Asian women are more vulnerable to this birth complication. The lack of an international standard definition for the term Asian further undermines clarification of this issue. Nevertheless, there is an urgent need to explore why Asian women are reported to be significantly at risk for severe perineal trauma in some Western countries.ConclusionCurrent research on this topic is confusing and conflicting. Further research is urgently required to explore why Asian women are at risk for severe perineal trauma in some birth settings. 相似文献

Abstract Objective: Alcohol has been linked to a variety of risky sexual practices, including inconsistent condom use. Due to the high rates of alcohol consumption among underage college women, greater understanding of the role of alcohol in young women's sexual decision making is warranted. Participants and Methods: Female underage (18- to 20-year-old) social drinkers (N = 94) participated in an experiment in which they projected themselves into a written hypothetical sexual situation with a new partner. One half of the situations portrayed alcohol consumption; one half did not involve alcohol consumption. Their appraisals of the situation's sexual potential, impelling and inhibiting cognitions, and sexual behavior intentions were assessed. Results: Results revealed that alcohol's expectancy effects on young women's unprotected sexual intentions were mediated by their cognitive appraisals of the situation. Conclusions: These findings indicate that alcohol expectancies and their influence on women's sexual decisions should be incorporated into sexual risk reduction efforts. 相似文献

Ageist attitudes have been identified across different industries. The nursing profession has a high proportion of older workers. As this facilitates regular contact with, as well as exposure to, older nurses, it may be expected to show less ageism. This study investigated 163 Western Australian nursing recruiters' attitudes toward older nurses. Results showed clear evidence of both negative and positive stereotyping of older nurses. Nursing recruiters indicated that they would be more than likely to hire older nurses and that age was less relevant in making hiring decisions. These findings suggest that enhancing the employability of older workers does not necessarily change ageist attitudes. This is relevant to policy formulation, attitude change interventions, and the well-being of older workers. 相似文献

This paper presents a conceptual framework for viewing social planning and social administration as one “seamless web” of activity concerned with the identification of goals and the development of appropriate administrative structures for their implementation. The major educational implication of this analysis is that curriculum planning should maximize the integration of social policy, social planning, and administration. Alternative approaches to achieving this integration are discussed using data from a recent Council on Social Work Education survey. 相似文献

This exploratory study examined how seasoned White social workers grappled with the presence and effects of White privilege on their clinical practice. Data were collected in focus groups; findings were surfaced through thematic analysis. Five themes emerged: the role of engaging in continuous self-awareness in clinical practice; the complexity of using intersectionality to inform our work; the necessity of addressing White privilege in clinical conversations; the importance of creating strategies for use of power; and the process of engaging in life-long growth. These workers demonstrated awareness of, and accountability for, White privilege. Implications for progressive social work practice are discussed. 相似文献
