Jacqueline Ellis 《Feminist Review(on-Line)》1996,53(1):74-94
This article had several purposes. First, I wanted to highlight the work of Esther Bubley, an American photographer whose documentary work for the Farm Security Administration and the Office of War Information in the early 1940s is largely unknown. Second, I wanted to show how her images complicated and undermined the traditional themes of Depression era photography in the United States. Third, by looking at her images of women, my intention was to reveal how she worked against depictions of femininity during the Depression, and in confrontation with one-dimensional portrayals of women as America entered the Second World War. In conclusion, I contend that Bubley's images were fundamentally portrayals of working-class femininity represented as being an individual - rather than a symbolic - experience. Most specifically in the images I have examined, Bubley deconstructs an ideological image of female working-class identity which was central to documentary photography in 1930s America. For example, unlike in photographs by Dorothea Lange, Bubley did not portray working-class women as metaphoric sites of passive endurance which would eventually lead to the rejuvenation of American nationalism. Rather, she showed working-class women to be potentially subversive in the ways they defined themselves against the legacy of 1930s photography and in opposition to the ideological impositions of wartime propaganda. As a result, Bubley's images of working-class women waiting in bars for lonely soldiers, or looking for a future beyond the confines of their boarding house existences while remaining outside the middle-class boundaries defined by capitalist consumerism, set out a pictorial foundation for working-class female identity which exists beyond the context in which the photographs were taken. Consequently, Bubley's work highlights individual self-identity, personal empowerment and self-conscious desire in working-class women which was - and still is - confined and repressed by economic disadvantage and systematic marginalization from an American society defined from a middle-class point of view. 相似文献

The Skinny on Body Dissatisfaction: A Longitudinal Study of Adolescent Girls and Boys 总被引:3,自引:1,他引:3
The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders, parental support deficits, negative affectivity, and self-reported dietary restraint showed significant relations to future increases in body dissatisfaction. Ideal body internalization and body mass index did not demonstrate significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects.

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement. 相似文献

Efficient capillary electrophoretic STR analysis requires rapid, reproducible and robust separation of DNA fragments with reasonable capillary longevity--this is currently accomplished using proprietary commercial polymeric sieving matrices specifically developed for this separation. These matrices, while effective, are costly and do not provide adequate resolution of STR DNA fragments in capillaries with shorter effective separation lengths, increasing the time required to accomplish the separation and minimizing the potential extrapolation to other miniaturized platforms. As the forensic community looks toward next generation microchip technology as a means of processing casework more rapidly, new sieving polymers need to be evaluated for utilization in this platform. The research presented here describes the assessment of commercially-available polymeric sieving matrices for STR analysis, with consideration given to feasibility of incorporation into a microdevice. Polymer composition, molecular weight, and concentration were evaluated, along with an assessment of the effects of buffer composition, separation temperature, and capillary length. These variables were evaluated individually or collectively on the ability to resolve STR DNA fragments and the reproducibility of the separations and the results compared to a proprietary commercial product. A 600,000 Da MW poly(ethylene oxide) (PEO) solution at a 3% (w/v) concentration was determined to be the most suitable matrix for these separations. This polymer, in coated capillaries, provided highly robust and reproducible separations, with near baseline resolution of fragments having single base differences. Reductions in the temperature of the separation, from 60 degrees C to 40 degrees C, and the urea concentration of the buffer, from 7 M to 3.5 M, provided increased longevity of the PEO polymer for repeated separations. Comparison of this polymer with currently specified commercial products used for STR analysis showed that the optimized PEO matrix provided superior separations under all conditions tested. In addition, PEO could be utilized in shorter capillary systems, with a concurrent decrease in analysis time, highlighting its potential for use in shortened capillary or microdevice systems. 相似文献
