In this essay, the authors, all experimental filmmakers, discuss the impact of Born in Flames on their own work, as well as the ways their various projects pick up, extend, or change the political questions raised by the film. The relationships of experimental film to political community and community building are explored, particularly in the context of queer, feminist, trans, anti-racist politics and media.  相似文献

There are complex and interesting representational issues and interpretational practices involved in claiming to ‘know past lives’ and these have particular resonance in feminist terms. These ideas are examined in relation to a particular case study, of the feminist writer and theorist Olive Schreiner (1855-1920), although the discussion contributes to the ‘women's history and post-structuralism’ debate by eschewing taking up an abstract ‘position’ in favour of examining these ideas through a grounded historical example. A range of representations of Schreiner is discussed, including a photograph which her estranged husband contemporaneously had ‘touched up’ before sending it to some of her friends just after her death, and presentday representations of Schreiner in the emergent feminist canon of claimed knowledge about her. The ideas of mimesis and alterity are used both in relation to photographic representation and also in relation to the use of metaphor to stand for perceived facets of Schreiner's character. Representational issues are fundamental and ought not to be excised from feminist discussion; at the same time, the past and its ‘irreducible things that happened’ must also be taken seriously.  相似文献

This study seeks to explain why U.S. local governments utilize environmental sustainability to promote economic development. Economic development and environmental protection need not be competing objectives, but rather, environmental protection can enhance local economic competitiveness. Using data from the ICMA Economic Development Survey, this study tests an empirical model that includes state sustainability initiatives, participation in climate protection networks, and political attitudes toward economic development as predictors of local policy decisions. The findings reinforce a multi-level governance perspective on explaining the balance cities seek to achieve between environmental protection and economic growth.  相似文献

In an effort to increase both adolescents’ engagement with school and academic achievement, school districts across the United States have created small high schools. However, despite the widespread adoption of size reduction reforms, relatively little is known about the relationship between size, engagement and outcomes in high school. In response, this article employs a composite measure of engagement that combines organizational, sociological, and psychological theories. We use this composite measure with the most recent nationally-representative dataset of tenth graders, Educational Longitudinal Study: 2002, (N = 10,946, 46% female) to better assess a generalizable relationship among school engagement, mathematics achievement and school size with specific focus on cohort size. Findings confirm these measures to be highly related to student engagement. Furthermore, results derived from multilevel regression analysis indicate that, as with school size, moderately sized cohorts or grade-level groups provide the greatest engagement advantage for all students and that there are potentially harmful changes when cohorts grow beyond 400 students. However, it is important to note that each group size affects different students differently, eliminating the ability to prescribe an ideal cohort or school size.  相似文献

The understanding of positive development across adolescence rests on having a valid and equivalent measure of this construct across the breadth of this period of life. Does the Positive Youth Development (PYD) construct based on the Five Cs model have satisfactory psychometric properties for such longitudinal measurement invariance? Using longitudinal data derived from the 4-H Study of PYD, we assessed 920 youth (61.6% female) from a racially and ethically diverse sample (67.3% European American) who participated in three waves (Grades 8–10) of data collection. Building on prior findings that the Five Cs (i.e., Competence, Confidence, Connection, Character, and Caring) model of PYD was a robust measure that could be assessed comparably during early adolescence, we tested a hierarchy of second-order confirmatory factor analysis models to assess the extent to which PYD can be measured equivalently across middle adolescence. Evidence was found for strict measurement invariance across three measurement occasions, including equivalence of first-order and second-order factor loadings, equality of intercepts of observed variables, and equality of item uniqueness and disturbances of the first-order factors. These results suggest that PYD can be measured in the same way across measurement occasions, a prerequisite for the study of development. Implications for research and application of being able to measure PYD equivalently across adolescence are discussed.  相似文献
