ABSTRACT Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall. 相似文献

It has been 20 years since Robert J. Bursik Jr. published his seminal article outlining some of the problems and prospects in the social disorganization perspective on crime and delinquency. In this study, we review the content of approximately 200 published articles that cite Bursik’s 1988 piece. These studies are systematically examined in terms of their efforts to overcome the problems and pursue the prospects that Bursik outlined. In addition to content analysis, we survey the authors who cite this work. That is, we gather data from the authors directly to assess the influence of Bursik’s article on their own published work. Our research finds that Bursik’s work played a significant role in the revitalization and expansion of social disorganization theory. 相似文献

This study investigated the effect of a single session of resistance exercise on postprandial lipaemia. Eleven healthy normolipidaemic men with a mean age of 23 (standard error = 1.4) years performed two trials at least 1 week apart in a counterbalanced randomized design. In each trial, participants consumed a test meal (1.2 g fat, 1.1 g carbohydrate, 0.2 g protein and 68 kJ x kg(-1) body mass) between 08.00 and 09.00 h following a 12 h fast. The afternoon before one trial, the participants performed an 88 min bout of resistance exercise. Before the other trial, the participants were inactive (control trial). Resistance exercise was performed using free weights and included four sets of 10 repetitions of each of 11 exercises. Sets were performed at 80% of 10-repetition maximum with a 2 min work and rest interval. Venous blood samples were obtained in the fasted state and at intervals for 6 h postprandially. Fasting plasma triacylglycerol (TAG) concentration did not differ significantly between control (1.03 +/- 0.13 mmol x l(-1)) and exercise (0.94 +/- 0.09 mmol x l(-1)) trials (mean +/- standard error). Similarly, the 6 h total area under the plasma TAG concentration versus time curve did not differ significantly between the control (9.84 +/- 1.40 mmol l(-1) x 6 h(-1)) and exercise (9.38 +/- 1.12 mmol x l(-1) x 6 h(-1)) trials. These findings suggest that a single session of resistance exercise does not reduce postprandial lipaemia. 相似文献

Mentoring students through collaborative research can be an effective method for cultivating student development as scholars; but negotiating the division of responsibilities and recognition may be difficult due to the inherent complexities of the relationship between collaborators and the research process itself. A national sample of 440 students and faculty in education and social science disciplines described their positive and negative experiences with authorship determination in student–faculty collaborative research. Qualitative analysis of these responses revealed important themes and informed the development of suggestions for articulating authorship to avoid potential difficulties. 相似文献

Children with Behavioural and Emotional Difficulties: Complex Children,Complex Training for Teachers
This paper consists of two parents’ accounts of their experiences of having children with AD/HD. The article is divided into three distinct sections. In the first section the mother of ‘Simon’ describes her experience of bringing up a child who, from early infancy, presented challenging behaviour. She describes the effect of this on her family and her self esteem as a parent. She goes on to give an account of the process by which ‘Simon’ came to be diagnosed as having AD/HD and the effects of the ensuing treatment programme. In the second section the same writer describes the impact of her experience on her relationships with the extended family. The third section of the paper is provided by a second writer, who is also the mother of a child with AD/HD. This section focuses on the difficulties she experienced in dealing with her child's educational needs and the conflicts which arose between her and staff in her child's school. 相似文献
