Black male: Advertising and the cultural politics of masculinity   总被引:1,自引:0,他引:1  
During the 1980s, men's bodies began to appear with increasing frequency in television, cinema and billboard advertising. The advertisers’ preferred image of masculinity has generally been young, white, able‐bodied and staunchly heterosexual. This paper explores a partial exception to these generalisations: Ogilvy & Mather's highly successful relaunch of the soft drink, Lucozade. By using selected images of black male bodies and their popular associations with sporting and sexual prowess, Lucozade was able to shake off its long‐established associations with sickness and convalescence, becoming a popular ‘in‐health’ drink with a revitalised and revitalising image. The paper places contemporary representations of black men in British advertising in relation to wider changes in attitudes towards gender, sexuality and ‘race’, arguing that the success of the Lucozade campaign depended not so much on general associations between sport and ‘race’, manliness and muscularity, as on the reader's (socially constructed) knowledge of the particular personalities represented. This assumed knowledge effectively suppresses the more threatening aspects of a stereotypically anonymous and rapacious black male sexuality, provoking desire without evoking dread.  相似文献

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the PN+1DG‐PNDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.  相似文献

One hundred and ninety three glass fragments from the canabae in York were analysed (first to fourth centuries). They fall into six compositional groups: antimony colourless (Sb), high‐manganese (high‐Mn), low‐manganese (low‐Mn), mixed antimony and manganese (Sb–Mn), high iron, manganese and titanium (HIMT) and plant ash. Some groups represent production groups, some of which appear to be in limited supply in this western outpost, but are more prevalent elsewhere, and others reflect changing supply mechanisms. The majority of glasses fall into groups that demonstrate extensive recycling of glass. This has important implications for determining provenance using trace elements and isotopes.  相似文献

Conversations around, and conceptions of, citizenship have changed over time. Assumed initially as a mark of membership, of belonging to a political community (Marshall 1950), the essence of what it means to be a citizen and what the contractual ties of citizenship are have evolved over time. This evolution has been encouraged by processes of migration and increasing mobility. More recently, our ability to traverse geographical and political boundaries has meant that notions of borders and boundaries, of who belongs where and why, have also been subject to dramatic changes. This article investigates the impact of such mobility on the individual lived experience of migrant women who, as a group, have been traditionally excluded from more formal political arenas, and asks questions of what citizenship means for them. Though I do not contest the very political fact of citizenship as status, this article challenges the way in which the nature of this status is assumed or implied for all. This article therefore argues that citizenship itself is a much more fluid concept, incorporating the emotional and lived experience of individuals and that it is in these emotional accounts through which citizenship, and its extended rights and political capabilities, must be understood through a sense of everyday, grounded and personal politics.  相似文献

The extensive analytical focus on how gender relations in working lives, employment, education, political engagement and public life change under modernity needs extension into a consideration of the ways in which kinship and relatedness have also been changing. This article argues that relatedness under modernity tends towards matrifocality. This is explored through looking at broad patterns of social change in kinship practices across a range of societies experiencing transitions towards modernities over the past fifty years, and at how state and NGO development and social protection programmes contribute to this matrifocal turn.  相似文献

A boy’s suit of fawn wool sold by H. J. & D. Nicoll of London, dated c. 1860, in the Fashion Museum, Bath, raises a number of issues. Combining the long trousers worn by adolescents with a jacket associated with younger boys, it marks a turning point in age-related dress codes. Mass produced but with hand stitching, it presents evidence of the exploitative practices Nicoll had been charged with in Henry Mayhew’s Morning Chronicle letters in 1850. The prominent labelling of the suit relates to Nicoll’s publicity strategies and to the importance of boys’ clothing for ready-to-wear retailers. A comparison of the suit with other surviving garments and with marketing documents illuminates the way that Nicoll positioned itself within the retail market. The rarity of this survival and the scarcity of information on a high-profile and long-lasting retailer make this an important case study for investigating the origins of the ready-to-wear clothing trade in Britain.  相似文献
