This article describes and highlights the potential contributions that the constructs multifinality, work hope, and possible selves make for designing career counseling interventions and for better understanding possible career‐related factors associated with academic engagement and achievement among urban minority youth. Multifinality may serve as a superordinate orientation because it conceptualizes development as discontinuous and relatively plastic, allowing for youth deemed at risk to follow more hopeful pathways. Work hope and possible selves emphasize the utility of providing urban minority youth with space to answer questions related to what they might achieve and do in the future and who they might become. Together, multifinality, work hope, and possible selves provide a hopeful conceptual framework for career researchers and practitioners.  相似文献

The purpose of this study that focused on African American high school girls was threefold. First, the relationship of sports participation and victimization was explored. Second, the impact of sports participation on self-esteem was assessed. Third, the role of self-esteem and its disaggregated components (social acceptance, competence, and self-confidence) as mediators of the relationship between sports participation and victimization was examined. In accordance with the sport protection hypothesis, it was hypothesized that sports participation would be related to enhanced self-esteem and reduce victimization. Results suggest that sports participation appears to have some relationship to lower rates of victimization. There was also support for our assertion that sports participation was related to enhanced self-esteem. Finally, overall self-esteem and, specifically, the individual component competence mediated the relationship between sports participation and victimization.  相似文献

This article examines the role that women’s cultures and communities have played in political protest and social change. We argue that women’s cultures, which form around the reproductive roles, labor, and emotional expectations placed on women, have been used to express femininity and as cultural resources or “toolkits” to transform male‐dominated spheres of society. We begin by defining women’s cultures, emphasizing that there is no universal women’s culture because the structural arrangements and cultural meanings of gender vary by race, ethnicity, class, nationality, and political context. We then review research that demonstrates the significance of women’s cultures for the collective identities and tactics deployed in social movements and protest, demonstrating how the study of women’s cultures and gender processes in social movements has contributed empirically and theoretically to understanding social movements. We examine women’s cultures and collective identities in communities as wide ranging as self‐help groups, lesbian communities, feminist organizations, and anti‐feminist groups. We then draw on prevailing theories of cultural change in globalization studies (cultural differentialism, cultural convergence, and cultural hybridization) to understand how women’s cultures have contributed to social change. We conclude by identifying future directions for the study of women’s cultures and social movements.  相似文献

Maya heritage is embraced throughout Yucatán as a crucial component of tourism promotions. This, coupled with an emphasis on multiculturalism, makes the state itself a local actor in the marketing of Maya identity through the creation and funding of community-based tourism projects. This article discusses the shifting role of the state in shaping these communities, referencing a Maya village in the Mexican state of Yucatán as the context. The aim is an understanding of the articulation of local tactics to conceal cosmopolitanism while remaining competent in the eyes of funding agencies and the strategies employed by the state that reinforce the importance of performance for tourists. The desire on the part of state creates situations in which individuals are expected to exist in concurrent states of authenticity and modernity, as both traditional and cosmopolitan.  相似文献

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision.  相似文献

The Japanese “just-in-time with kanban” technique reduces in-process inventory to absolute minimal levels, in concert with the Japanese belief that inventory is an unnecessary evil. Due to the success of Japanese firms that employ this type of system, American firms would like to import this technique and emulate Japanese successes. But this Japanese success may be attributable not only to the just-in-time with kanban technique but also to the production environment in which the technique is employed. This paper simulates the just-in-time with kanban technique for a multiline, multistage production system in order to determine its adaptability to an American production environment that might include such characteristics as variable processing times, variable master production scheduling, and imbalances between production stages. The results have practical implications for those firms considering adoption of the Japanese technique.  相似文献

While the literature is extensive on school districts' revenue sources, less research has been done on the impact of donations on school district funds. In this paper, we extend the theoretical literature on crowding out of private donations by government grants for one type of nonprofit firm, namely charter schools. The theoretical model leads us to focus on the key relationships among fundraising effort, enrollment (which is tied to federal and state funding) and donations. Using a dataset on Texas charter schools we adopt a two-stage approach to examine the empirical relationship between changes in nondonor revenues and the donations received by charter schools. Like the extensive empirical estimates of the effects of government grants on donations for other types of nonprofit firms, we find evidence of crowding-out with respect to our sample of charter schools. We also find a significant, positive effect of fundraising on donations with a $1 increase in fundraising associated to a $0.58 increase in donations, a pattern consistent with overinvestment in fundraising. Enrollments exhibit a robust inverse relationship to changes in nondonor revenues. (JEL H00, H32, H50)  相似文献

We describe inferactive data analysis, so-named to denote an interactive approach to data analysis with an emphasis on inference after data analysis. Our approach is a compromise between Tukey's exploratory and confirmatory data analysis allowing also for Bayesian data analysis. We see this as a useful step in concrete providing tools (with statistical guarantees) for current data scientists. The basis of inference we use is (a conditional approach to) selective inference, in particular its randomized form. The relevant reference distributions are constructed from what we call a DAG-DAG—a Data Analysis Generative DAG, and a selective change of variables formula is crucial to any practical implementation of inferactive data analysis via sampling these distributions. We discuss a canonical example of an incomplete cross-validation test statistic to discriminate between black box models, and a real HIV dataset example to illustrate inference after making multiple queries on data.  相似文献
