We used the Moving to Opportunity (MTO) housing experiment to inform how Housing Choice Vouchers and housing mobility policies can assist families living in high-poverty areas to make opportunity moves to higher quality neighborhoods, across a wide range of neighborhood attributes. We compared the neighborhood attainment of the three randomly assigned MTO treatment groups (low-poverty voucher, Section 8 voucher, control group) at 1997 and 2002 locations (4–7 years after baseline), using survey reports, and by linking residential histories to numerous different administrative and population-based data sets. Compared with controls, families in low-poverty and Section 8 groups experienced substantial improvements in neighborhood conditions across diverse measures, including economic conditions, social systems (e.g., collective efficacy), physical features of the environment (e.g., tree cover) and health outcomes. The low-poverty voucher group, moreover, achieved better neighborhood attainment compared with Section 8. Treatment effects were largest for New York, New York, and Los Angeles, California. We discuss the implications of our findings for expanding affordable housing policy.  相似文献

This article focuses on the organizational factors of environmental sustainability implementation in local government. We investigate the interactions, as well as direct and indirect impacts, of the framing of environmental sustainability and organizational culture and structure on implementation outcomes. We use a survey of 217 city/county planners and managers in 146 randomly selected American mid-sized cities and counties. The survey was specifically designed to tease out organizational features and their impacts. We model these impacts using structural equation modeling. We find that horizontally and vertically integrated organizational structure supports two essential dimensions of organizational culture: innovation adoption and consensus building. These cultural traits positively impact the framing of environmental sustainability at the core of organizations’ logic, which in turn significantly supports implementation outcomes. These findings provide important insights into city/county managers seeking to promote sustainability, and provide a base for future studies of the organizational factors of implementation.  相似文献

Achievement, engagement, and students’ quality of experience were compared by racial and ethnic group in a sample of students (N = 586) drawn from 13 high schools with diverse ethnic and socioeconomic student populations. Using the Experience Sampling Method (ESM), 3,529 samples of classroom experiences were analyzed along with self-reported grades. Similarities and differences in achievement, engagement, and quality of experience among white, black, Latino, and Asian students were examined. The most marked differences found were between black and white students. Consistent with several previous studies, an engagement–achievement paradox was found in which black students reported higher engagement, intrinsic motivation, and affect in classrooms, but lower GPA relative to white students. A similar engagement–achievement paradox was found for students from low SES communities compared to those from high SES communities. Analyses also revealed racial and ethnic differences in the relationship of engagement with on-task behavior and contextual factors. Being on-task when in classrooms had a more positive effect on the engagement of black students relative to white students. The contextual effect of being in school versus home or in public on engagement was also more positive for black students than white students. Contextual factors and measurement issues are emphasized in the interpretation of findings and suggestions for future research.

David J. Shernoff   is an Assistant Professor of educational psychology at Northern Illinois University broadly interested the relationship between human development and education. He completed his doctoral studies at the University of Chicago and the Sloan Center for Working Families, where he applied Mihaly Csikszentmihalyi's theory of flow and Experience Sampling Method (ESM) to the study of engaging educational contexts. From 2000 to 2003, he served as a post-doctoral fellow at the University of Wisconsin, Madison. His recent publications include “Engagement in after-school program activities: Quality of experience from the perspective of participants” in Journal of Youth and Adolescence (Shernoff and Vandell 2007). Jennifer A. Schmidt   is Associate Professor of Educational Psychology at Northern Illinois University. Her research focuses on the nexus of subjective experience, context, and individual development by examining the ways in which social, cultural, and situational circumstances mold experience, which in turn affects development. She earned her PhD. in Psychology: Human Development from the University of Chicago in 1998, where she studied how adolescents’ daily experiences with challenge fosters resilience among adolescents facing adversity. Following the completion of her doctoral studies she was appointed Research Director for the University of Chicago’s Sloan Center on Parents, Children and Work, housed within the National Opinion Research Center. In 2001 she joined the faculty at NIU, where she teaches courses in Educational Psychology and Child Development, Research Design, and Motivation.  相似文献

This paper focusses on the negotiations in which many subaltern peoples engage within contexts of unequal power relations in colonial settings like eighteenth-century Peru. The trial and ‘confession’ of Micaela Bastidas, an indigenous mestiza and wife of the Inca rebel Túpac Amaru II, allows for an analysis of the complexity of her subjectivity and agency, both as products of colonial impositions and Andean notions of gender complementarity and power. As a woman, wife of a noble curaca and member of a conquered indigenous population, she defied rigidly bipolar colonial ethnic and gender norms. Skilfully engaging in ‘rituals of subordination’ through the manipulation of discriminatory colonial expectations, Micaela refused to share what was expected of her, subverting colonial gender and power hierarchies, albeit momentarily.  相似文献

Atherosclerotic calcifications, as calcified atheromatous elements, are markers of cardiovascular disease. However, the literature gives little information regarding their morphological aspect, making their identification very rare in skeletonized cases. In this paper, we document the morphological, histological, and SEM aspects of atherosclerotic plaques collected from unclaimed cemeterial skeletal remains from an identified osteological collection and extracted from well‐preserved cadavers autopsied at the medico‐legal institute of Milan. Each of the three analyses provided similar results: atherosclerotic calcifications are convex‐concave plaques with a stratified structure, a pale‐yellow coloration in autopsy cases and yellow to brown when recovered in dry bone. Histologically, undecalcified and decalcified sections showed a stratified aspect formed by superimposed layers. Lastly, the SEM analysis showed a precise view of the stratified structure of the plaques in transverse section. As markers of disease, atherosclerotic calcifications can provide important antemortem information on the deceased that may be compared to antemortem data.  相似文献

ABSTRACT

In view of the multitude of challenges urban public administration is struggling with, more and more cities are turning towards smart solutions using information and communication technology. Such Smart City approaches revert to data provided in the urban space by sensors, by citizens or by the archives of the authorities aiming at providing public services that increase the quality of life for citizens, optimize mobility within the city or enhance flexibility and responsiveness of public authorities. This article identifies such SC approaches as well as their basic technical requirements for the cities of Vienna, Singapore, and San Francisco and, by compiling the public service portfolios of these cities, creates an integrative, strategic overview of a SC’s range of services. This approach thus helps to create a scientific basis for the evaluation of SC services and to provide a strategic modular toolkit for public managers to plan and design SCs.  相似文献

Commotio cordis secondary to a blunt blow to the chest wall can result in ventricular fibrillation and sudden death in children. While it is commonly reported in adolescents during sporting activities, it may result from non-accidental trauma especially in infants and younger children. We report a case of a 6-month-old baby boy who presented to the emergency department in cardiac arrest. The patient's hospital records, postmortem imaging, and the autopsy results were reviewed. External examination of the infant did not reveal any evidence of trauma. Postmortem imaging revealed multiple healing posterior rib fractures and a metaphyseal corner fracture, both considered fractures highly specific for physical abuse. The autopsy revealed a structurally normal heart with no microscopic abnormalities. The infant's father confessed to hitting the child on the chest after which the child became unresponsive. Given the constellation of postmortem imaging and autopsy findings in addition to the father's confession, the child's death was ruled as a homicide secondary to commotio cordis. Since there are no structural and microscopic abnormalities in the heart autopsy in cases of commotio cordis, timely on-scene investigation and a thorough investigation regarding the mechanism of injury are required to make this diagnosis. Early identification of non-accidental trauma is crucial and can prevent further abuse in other siblings.  相似文献
