This paper looks at the relationship between the discourses of racism and sexism and the configuration of school space in an Australian high school. I argue that school space is proliferative of racialised and sexualised divisions. Divisions can be identified between groups of 'Asian' girls, between 'Asian' girls and 'Asian' boys, and between 'Asian' students and 'non-Asian' students. While these divisions are legislated by discourses of racism and sexism, this paper focuses attention on 'Asian' girls response to this situation. I argue that against the experience of social marginality 'Asian' girls tactically reproduce differences. By highlighting the changing dynamics of spatial-social divisions in school, I show how 'Asian' girls contest and rework racialising/sexualising discourses to recompose 'Asian'/femininity.  相似文献

This paper explores the concepts of old‐growth forests, preservation and natural disturbance and demonstrates how contemporary biogeographic theory contributes to successful preservation of old‐growth forests. The case study analyzes the composition, structure, age and growth histories of trees in Big Timber Park, Whistler, British Columbia. Composition. The structure of the forest was diverse and tree ages ranged from 122 to 305 years. The densities of large old Douglas‐fir, shade‐tolerant trees and all snags are indicative of old‐growth forests; however, maximum tree diameters and densities of large snags and logs do not meet quantitative criteria for old‐growth forests. The abundance of tree regeneration and understory vegetation are relatively low. We conclude that some aspects of Big Timber Park are transitional between the mature and old‐growth stages of forest development. In the future, fine‐scale canopy gaps caused by tree senescence and interactions among insects, pathogens and wind are expected to dominate stand dynamics. Forest structure will become increasingly complex, exemplifying the dynamic nature of old‐growth forests. To successfully preserve Big Timber Park and La préservation des forêts other old‐growth forests in Canada requires understanding of natural disturbances. Preservation and the criteria and indicators used to measure successful preservation must explicitly include elements of natural change.  相似文献
