This article examines the representation of Black women's weight in contemporary diet advertising and African American film. It positions socioeconomic class as a significant factor that distinguishes between “good” weight and “bad” weight. I argue that there is a distinction to be made between representations of poor and working-class fat Black women and middle-class fat Black women. The increased presence of Black women as diet spokeswomen is also questioned. The social construction and filmic representation of the African American cuisine “Soul Food” and the political economic notion of neoliberalism are used as frameworks to deconstruct how notions of self-discipline, personal responsibility, and citizenship impact upon Black women's bodies. As a case study, I examine the careers of Oprah Winfrey and Gabourey Sidibe and the ways in which their weight has been differently coded based on class, the neoliberal rhetoric of “personal responsibility,” and food. I ultimately critique how contemporary media has helped to shape contemporary discourses on Black women's weight.  相似文献

Despite recent critical analyses of the nature and impacts of social and environmental certification, the increasingly complex landscape of voluntary, industry and third-party codes and certification processes that have emerged in specific sectors is poorly understood. In particular, little is known about the potential threats posed by an increasingly complex and contested ‘ethical’ landscape in undermining radical initiatives designed to bring about improvements to material and social well-being. In response, this paper explores the current dynamics of social and environmental certification in the South African wine industry. Drawing on fieldwork in the UK and Western Cape, the paper analyses the overlapping and sometimes conflictual processes of social and environmental certification, and the role of key drivers in establishing them within the wine industry. It explores whether attempts to capture a portion of the expanding market for ‘ethical’ wines and the expansion of corporate interests in ‘responsibility’ and ‘ethics’ work to depoliticize the meaning and nature of transformation. The implications of the findings are that, in the absence of legislative requirements to transform the wine industry, social codes and civic conventions are likely to remain significant, but that greater understanding is required of the different meanings and outcomes of transformation and empowerment being deployed within the industry. The paper concludes that a significant problem facing transformation and alternative trade in the wine industry, and more broadly, lies in the growing gap between the abstract ethical discourse of corporate actors, on the one hand, and the moral experience of workers on the other.  相似文献

Graph models have long been used in social network analysis and other social and natural sciences to render the analysis of complex systems easier. In applied studies, to understand the behaviour of social networks and the interactions that command that behaviour, it is often necessary to identify sets of elements which form cohesive groups, i.e., groups of actors that are strongly interrelated. The clique concept is a suitable representation for groups of actors that are all directly related pair-wise. However, many social relationships are established not only face-to-face but also through intermediaries, and the clique concept misses all the latter. To deal with these cases, it is necessary to adopt approaches that relax the clique concept. In this paper we introduce a new clique relaxation—the triangle k-club—and its associated maximization problem—the maximum triangle k-club problem. We propose integer programming formulations for the problem, stated in different variable spaces, and derive valid inequalities to strengthen their linear programming relaxations. Computational results on randomly generated and real-world graphs, with \(k=2\) and \(k=3\), are reported.  相似文献

A qualitative study of 24 quilters examined their experiences creating and delivering quilts to wounded service members who served in the Iraq and Afghanistan conflicts. Using Erikson’s (1963) perspective on generativity and Baumeister and Vohs’s (2002) theory of motivation as theoretical frameworks, along with McCracken’s (1988) five-step analysis model, we looked at the part motivation played in this process. The results were that respondents wanted to supply quilts in response to their own family histories of military involvement, to support friends/acquaintances with family in the military, and to make a difference to those who seemed young and badly wounded. Some respondents described being affected by the reactions of quilt recipients and of healing from their own traumas and grief.  相似文献

Firefighters are exposed to a wide range of risks, among them, biological risk. The objective was to analyze working conditions of firefighters in the city of Campo Grande, MS, Brazil, focusing on risk conditions of exposure to biological material. Three hundred and seven (307) firefighters were interviewed for data collection and observed for ergonomic job analysis (AET). Results: 63.5% of the firefighters suffered some kind of job related accident with blood or body fluids. Statistically significant association was found between having suffered accidents at work and incomplete use of personal protective equipment (PPE). About AET regarding the biological risks, 57.1% of all patients had blood or secretions, which corresponds in average to 16.0% of the total work time, based on a working day of 24 h. Besides biological risks, other stressing factors were identified: emergency and complexity of decision, high responsibility regarding patients and environment, and conflicts. Health promotion and accident prevention actions must be emphasized as measures to minimize these risks.  相似文献

Workplace accidents involving machines are relevant for their magnitude and their impacts on worker health. Despite consolidated critical statements, explanation centered on errors of operators remains predominant with industry professionals, hampering preventive measures and the improvement of production-system reliability. Several initiatives were adopted by enforcement agencies in partnership with universities to stimulate production and diffusion of analysis methodologies with a systemic approach. Starting from one accident case that occurred with a worker who operated a brake-clutch type mechanical press, the article explores cognitive aspects and the existence of traps in the operation of this machine. It deals with a large-sized press that, despite being endowed with a light curtain in areas of access to the pressing zone, did not meet legal requirements. The safety devices gave rise to an illusion of safety, permitting activation of the machine when a worker was still found within the operational zone. Preventive interventions must stimulate the tailoring of systems to the characteristics of workers, minimizing the creation of traps and encouraging safety policies and practices that replace judgments of behaviors that participate in accidents by analyses of reasons that lead workers to act in that manner.  相似文献

The article presents a step in the design of an experiment that has an emphasis on the following research question: how to assess the user friendliness of products in use? For this purpose, we developed three different approaches involving the use of products in intuitiveness. In this table, were removed some information regarding the positive aspects. These were broken down into procedures to be performed for an experiment with the same scope.  相似文献

The current article presents the process of situated modeling in the drawing workshop for bobbin lace developed and implemented in the Núcleo de Produ??o Artesanal Rendeiras da Vila, in Ponta Negra, Natal-Brasil. The workshop aimed to rescue the domain over the product in the production of bobbin lace through capacitation of both experienced and novice craftswomen. The modeling of the drawing workshop was grounded on the sociotechnical construction and in the concepts of anthropotechnology and also social technology. The modelling required an intense process of social construction involving the members of GREPE-UFRN (Group of extension and Research in Ergonomics) and the lacemakers od the community. The domain of drawing the lace has enabled the expression of the craftswomen creativity, increasing the amount of works and the sustainable development,thus reducing the risks of extinction of such art in the Village of Ponta Negra.  相似文献

Abstract

The formal conventions of global humanitarianism when performed as melodrama, structured around temporal devices such as peripeteia, deferral, delay, and missed chances, reveal some of its affect-making roles in globalization. The melodramatic flourishing of Live Aid commemorative events and commodities in the twenty-first century suggests there is a melancholic attachment to Euro-American global hegemony, retroactively and repetitively constructed as a missed chance to do good that always meant well. The melodramatic enactment at Live 8 of the ‘end’ of global poverty promised by Live Aid patches over the discontinuities between the era of development internationalism and neoliberal globalization, creating a moralized image of Euro-American globalization as a ‘long-standing’ form of humanitarian power that can be lamented in place of confronting the absence of any alternative explanatory framework for escalating processes of uneven development. By suspending time, melodrama creates a fantasmatic site for aspiration, ambivalence, melancholy, and nostalgia without resolving their contradictions.  相似文献

Using a daily diary design, the current study assessed within‐person associations of work‐to‐family conflict with negative affect and salivary cortisol. Furthermore, the authors investigated whether supervisor support moderated these associations. Over 8 consecutive days, 131 working parents employed by an information technology company answered telephone interviews about stressors and mood that occurred in the previous 24 hours. On Days 2–4 of the study protocol, they also provided 5 saliva samples throughout the day that were assayed for cortisol. Results indicated a high degree of day‐to‐day fluctuation in work‐to‐family conflict, with employed parents having greater negative affect and poorer cortisol regulation on days with higher work‐to‐family conflict compared to days when they experience lower work‐to‐family conflict. These associations were buffered, however, when individuals had supervisors who offered support. Discussion centers on the use of dynamic assessments of work‐to‐family conflict and employee well‐being.  相似文献
