This paper explores how remittances influence happiness among migrants and their households of origin. It is based on a novel data set of matched samples of Bangladeshi migrant households (living in the UK and Malaysia) and their origin families in Bangladesh. Empirical findings suggest that remittances play a significant role in stimulating migrants’ happiness. We also find that the households of origin’s life satisfaction not only depends on receiving remittances from the emigrants, but also other factors such as number of migrants from the household living abroad and the migrants’ country of destination.  相似文献

In the film fragment Smart B**ch, two women—a black Sudanese-Australian and a white American-Australian—share what it means to be diasporic travellers and explore their similarities and differences within evolving feminist discourses which have in some ways abandoned the subaltern for the subdivided. No longer content to criticise the ways in which we speak for and to each other, and to accommodate hierarchies of class, race and sexuality, this ethnocinematic dialogue prefers these film personae to speak with each other and their audience using Conquergood and Denzin as performance ethnography guides, while challenging hegemonic notions of diaspora to include such diversities as adoptees, queers, and others.  相似文献

The period 1880–1930 saw women composers achieve unprecedented prominence as composers of large-scale works. This success coincided with the first wave of feminist movements in England, France and Germany. This article views the junctions where these two groups of women met through the vehicle of the feminist press, documenting the tensions and misunderstandings that occurred between emerging women composers attempting to be taken seriously as creative entities and feminists seeking to improve the political, social and professional lot of women. The pervasive aesthetic of male musical genius remained unquestioned by many feminists in spite of examples of female creative brilliance.  相似文献

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners.  相似文献

This study examined the effects of neighborhood context on juvenile recidivism to determine if neighborhoods influence the likelihood of reoffending. Although a large body of literature exists regarding the impact of environmental factors on delinquency, very little is known about the effects of these factors on juvenile recidivism. The sample analyzed includes 7,061 delinquent male juveniles committed to community-based programs in Philadelphia, of which 74% are Black, 13% Hispanic, and 11% White. Since sample youths were nested in neighborhoods, a hierarchical generalized linear model was employed to predict recidivism across three general categories of recidivism offenses: drug, violent, and property. Results indicate that predictors vary across the types of offenses and that drug offending differs from property and violent offending. Neighborhood-level factors were found to influence drug offense recidivism, but were not significant predictors of violent offenses, property offenses, or an aggregated recidivism measure, despite contrary expectations. Implications stemming from the finding that neighborhood context influences only juvenile drug recidivism are discussed.  相似文献

In this study, we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). We utilize an extensive database covering the universe of teachers and students in Florida for a four‐year span to determine the relationship between NBPTS certification and the impact of teachers on student test scores from both low‐stakes and high‐stakes exams. Contrary to some previous studies, we find evidence that NBPTS certification provides a positive signal of a teacher's contribution to student achievement only in a few isolated cases. However, our results do reinforce evidence from previous research that the process of becoming NBPTS certified does not increase teacher productivity. © 2009 by the Association for Public Policy Analysis and Management.  相似文献
