Presidential Address: The Faculty Time Divide

The time demands of academic life are examined, drawing on data from a large national sample of faculty. I outline the divide between full-time faculty, who work long hours irrespective of rank or institution type, and part-time faculty, who work at low pay with little job security, status, recognition, or fringe benefits. The expectations of academic life in dual-career couples are hard to reconcile with the demands of parenting. This is a common problem because assistant professors are generally too old to wait until they have tenure to have children. The segmentation of academic life into an overworked core and a marginalized periphery tends to perpetuate gender inequality.     

The Design And Analysis of a Mixture Experiment on Glass Durability

This paper discusses the statistical design and analysis of a non–standard constrained mixture experiment on glass durability (the components sum to 1, and there are non–trivial lower or upper bounds on components or combinations of them). It notes some of the difficulties which arose during the study, and shows how the aims and methods of the experiment changed during its execution.

论性别不平等在中国女性就业领域的影响因素及对策——“玻璃天花板效应”分析

玻璃天花板作为当前社会客观存在的现象,阻碍了女性职业发展的道路,这不仅与社会现代化不相符,更不利于社会和谐。本文通过对玻璃天花板含义及现状分析,并从性别平等角度指出玻璃天花板现象产生的原因,提出要从女性自身、企业及政府等各方面应正视两性差异,给与女性公平的职业发展起点与机会,突破玻璃天花板的阻隔,构建两性平等的和谐社会。     

室内设计中玻璃语言的时间性与空间性

浅谈水泥路面“黑色化”的施工技术

水泥混凝土路面经过一段时间的使用后,往往会出现凹凸不平、断板、脱空裂缝、压碎等问题,目前对水泥混凝土路面通常采用沥青混凝土＂黑色化＂的改造方法。本文探讨了沥青混凝土＂黑色化＂改造的一些关键做法,指出既要了解旧的水泥混凝土路况并及时对旧的水泥路面进行病害的处理,又要处理好沥青加铺层的施工。     

Not only men but also migrants in non-traditional occupations

Domestic labour is considered a typical female job, and due to the arrival of large migration flows to Italy it has experienced a massive ethnicized connotation, peculiar of this sector. This paper focuses on how a double and subaltern condition of belonging to a ‘minority group’ affects gender perceptions of male migrant domestic workers and how they construct their masculinity.

This research is based on a comparison between 54 interviews with male and female migrant domestic workers, drawing on an intersectional approach based on gender and nationality. It shows how moving across borders, living in a host society, and working in a non-traditional job can reshape male immigrants' gender division perceptions, often in contradictory and unexpected ways. It also emerges how the ‘racial glass escalator’ allows reaffirmation of characteristics tied to the privileges of masculinity and furnishes an important and useful framework in which to analyse the experience of men in ‘female’ occupations.     

Introduction to critical perspectives and emerging models of inter-American studies

Abstract

Alfred Hitchcock’s Rear Window (1954) has been the subject of much critical attention, but the original story upon which it was based and its author, Cornell Woolrich, less so. This article examines ‘Rear Window’ (1942) in the context of Woolrich’s writing and his life more broadly, in order to reveal the privileged role of fenestral imagery in his work. Through a process which starts with surveillance through glass, and a creative interpretation of ‘real’ events consumed in terms strikingly similar to mass media entertainments, Woolrich’s marginalized protagonist assumes the role of the detective and, in doing so, his identity is enhanced. The Woolrichian window reifies abstract social boundaries. It serves, simultaneously, as a symbol of urban alienation and a fantasy of social integration. It also becomes a trope of consumption and popular culture. Hitchcock’s film has sometimes been praised for the self-conscious way in which it aligns the image of the window with the cinema screen in order to implicate viewers in the protagonist’s voyeuristic practice. This article extends such an analysis to Woolrich’s story, but also takes it a step further, to reveal the ways in which reading similarly might be regarded as a voyeuristic form of cultural consumption.
