Lesbian, gay, and bisexual (LGB) youths are over-represented in the homeless population. To examine why some LGB youths become homeless, this report compares homeless and non-homeless LGB youths. Of the 156 LGB youths, 48% reported ever being homeless (i.e., running away or being evicted from home). Results indicate that sexual orientation awareness and the initiation of sexual behavior occurred earlier in homeless than in non-homeless LGB youths and predated the first homeless episode. Substance use was more frequent and first occurred at an earlier age in homeless as compared to non-homeless LGB youths; however, substance use occurred subsequent to first homelessness. Childhood sexual abuse was associated with homelessness; and, early sexual orientation development was related to homelessness among youths without a history of sexual abuse. Findings suggest that interventions should help youths cope with their unfolding sexual orientation and work to prevent or address the consequences of sexual abuse.  相似文献

This article describes the role that schools are playing in supporting career development for young people. It examines the history of career-related programming in schools, including school-to-work programs, career and technical education, the college and career readiness movement, and current school reform initiatives. This understanding of schools' history, roles, opportunities, and constraints can help practitioners and policymakers think about how to build a system that supports youth development.  相似文献

To assist teachers in fostering students' global citizenship dispositions through service experiences, this article reports findings from a case study that investigated one high school's global service club and its impact on former club members' global awareness and global citizenship dispositions. Data were collected from Web-based documents and interviews with the faculty advisor and four former members. Data were analyzed by using the constant comparison method to elicit the following findings: (1) fundraising and awareness campaigns, when connected to a larger global service network, can act as viable local actions to combat global poverty; (2) club involvement can produce adults who feel more globally aware, but who do not necessary display critical understandings of global issues; and (3) club involvement can have a positive impact on global citizenship dispositions as participants reported feelings of empowerment and personal/social responsibility, yet no former club members continued participation in global service initiates as adults. Findings suggest the need for structural support when establishing high school global service clubs and, to optimize critical justice aims, local service actions should be tied to a more formal global citizenship curriculum.  相似文献

Extended enterprises face many challenges in managing the product quality of their suppliers. Consequently characterizing the quality risk posed by value‐chain partners has become increasingly important. There have been several recent efforts to develop frameworks for rating the quality risk posed by suppliers. We develop an analytical model to examine the impact of such quality ratings on suppliers, manufacturers, and social welfare. While it might seem that quality ratings would benefit high‐quality suppliers and hurt low‐quality suppliers, we show that this is not always the case. We find that such quality ratings can hurt both types of suppliers or benefit both, depending on the market conditions. We also find that quality ratings do not always benefit the most demanding manufacturers who desire high‐quality suppliers. Finally, we find that social welfare is not always improved by risk ratings. These results suggest that public policy initiatives addressing risk ratings must be carefully considered.  相似文献

This paper disentangles the impact of schools and teachers in influencing achievement with special attention given to the potential problems of omitted or mismeasured variables and of student and school selection. Unique matched panel data from the UTD Texas Schools Project permit the identification of teacher quality based on student performance along with the impact of specific, measured components of teachers and schools. Semiparametric lower bound estimates of the variance in teacher quality based entirely on within‐school heterogeneity indicate that teachers have powerful effects on reading and mathematics achievement, though little of the variation in teacher quality is explained by observable characteristics such as education or experience. The results suggest that the effects of a costly ten student reduction in class size are smaller than the benefit of moving one standard deviation up the teacher quality distribution, highlighting the importance of teacher effectiveness in the determination of school quality.  相似文献

This article responds to two questions: first, how are large local governments in East Africa responding to the emerging global economy? Second, is globalization a catalyst in enhancing local governance in Nairobi, Kampala, and Dar es Salaam? The paper is an empirical analysis of strategies adopted by local government organizations in search of meeting challenges brought by a globalization. While there are some similarities in the strategies and processes adopted, the implementation pace varies across the three organizations. At the end, an attempt is made to explain these differences.  相似文献

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.  相似文献
