Alors que le mouvement nord‐américain des femmes est surtout connu pour ses efforts en vue de transformer les relations sociales entre les femmes et les hommes, ses partisanes ont également mis l'accent sur la reformulation des relations entre les femmes. Utilisant une source de données novatrice, les mémoires du mouvement social, l'auteure souligne la profondeur de la déception que les féministes s'infligent les unes aux autres. Les mémorialistes débattent des notions provenant du mouvement et du courant principal voulant que les femmes soient compétentes socialement. Cet article présente le concept d'«idéation relationnelle» pour décrire la façon dont les mémorialistes féministes analysent d'une manière critique la compréhension de la socialité des femmes tenue pour acquise et aiguisent leurs désirs d'une nouvelle éthique sociale entre elles. While the North American women's movement is most known for its efforts to transform social relations between women and men, its adherents have also focused on remaking relations among women. Using an innovative data source, social movement memoir, this paper indicates the depth of disappointment feminists cause one another. Memoirists dispute notions found in the movement and mainstream that women are socially capable. The paper offers the concept “relational ideation” to describe the way feminist memoirists critically examine taken for granted understandings of women's sociality and amplify their desires for a new social ethic among them.  相似文献

Group technology has been used successfully for a number of years as a setup reduction tool. It is especially valuable in low-volume high-mix manufacturing environments where products and machines may be partitioned into product families and machine cells. The partitioning of machines or processes into cells may be limited by practical constraints, and the partitioning of products is complicated as the number of products and processes increases. In this paper, the authors examine the behaviour of various grouping strategies lauded as being appropriate in situations where machine partitioning and product routeing are determined by technological constraints. Of specific experimental concern in this paper is the effect of the mean and variance of component part commonality between products on system performance under various grouping strategies in a multiple-machine environment.  相似文献

Abstract.  In observational studies treatment may be adapted to the patient's state during the course of time. These covariates may in turn also react on the treatment under study, and so on. This makes it hard to distinguish between treatment effect and selection bias. Structural nested models aim at estimating treatment effect in such complicated situations, even when treatment may change at any time. We show that structural nested models can often be calculated with standard software, by using standard models to predict treatment as a tool to estimate treatment effect. Robins ( Survival analysis, Volume 6 of Encyclopedia of Biostatistics , John Wiley and Sons, Chichester, 1998) conjectured this, but so far it was unproven. We use a partial likelihood approach to choose the estimators and tests as a subclass of the estimators and tests in Lok (math. ST/0410271 at http://arXiv.org , 2004). We show that this is the class of estimators and tests that can be calculated with standard software. The estimators are consistent and asymptotically normal, and have interesting asymptotic properties.  相似文献

Correspondence to Ms C. Taylor, Research Fellow, Social Work Research Centre, University of Stirling, Stirling FK9 4LA. Summary This paper reports on a study carried out in 1991 based on questionnaireswhich asked 169 female and male social work students about theiraspirations and expectations in respect of promotion in theirfuture career. Underlying the study is a concern about the unequalrepresentation of male and female workers at management levelsin social services in the UK, there being at present a predominanceof male managers. The phenomenon is not regarded as unique tosocial services, but as part of the pattern of gender inequalityin the workforce as a whole. The view that women contribute to the phenomenon by a fundamentallack of interest in, or unwillingness to apply for, promotionwill be challenged. It will be argued that the differences inthe aspirations and expectations of male and female employees,which previous research studies have reported, may be an effectof the experience of the organization rather than a cause ofthe scarcity of female employees in promoted posts. The paper will focus on some of the findings, including students'aspirations and expectations, their opinions about the unequalrepresentation of men and women in social work management, theimplications of this for their own career and whether they considerthis issue is, or should be, a significant component of socialwork training.  相似文献

This paper examines the role that work incentives play in the determination of work hours. We use a conventional efficiency wage model to analyze how firms respond to worker preferences regarding wage-hours packages. In contrast to previous work, we study markets in which workers have heterogeneous preferences. In this context we demonstrate that job offers will specify both wages and work hours and many individuals will not be able to work their preferred number of hours. We show that the labor market equilibrium may be characterized by a less than optimal number of short-hour jobs.  相似文献

Une portion importante des écrits contemporains féministes étudie des mythes au sujet de la femme. L'analyse des mythes oraux classiques et l'analyse des mythes littéraires et des images de la femme dans la presse, la radio, et la télévision contribuent à une compréhension de l'élaboration des stéréotypes masculin/féminin dans notre société. L'article analyse une série de caricatures portant sur une ‘dirty old woman’ qui ont paru dans la revue Playboy. Myths about women are examined in an important segment of contemporary feminist writings. Analyses of classical oral myths, of literary myths, and of images of women in the press, radio, and television contribute to our understanding of the construction of male/female stereotypes in our society. This paper analyses a series of cartoons in Playboy magazine which focus on a ‘dirty old woman.’  相似文献
