ABSTRACT

This paper analyzes the relative roles of cultural and structural factors in the emergence and solidification of taxi driving as an ethnic occupational niche among Ethiopian immigrants in the Washington DC metropolitan area within the wider context of globalization and immigrant integration. An ethnic occupational niche is the concentration and specialization of members of an ethnic group in a particular occupational activity. Using data from the US Census Bureau and in-depth interviews with 25 (male) Ethiopian cab drivers and three Ethiopian cab company owners, it examines the factors that affected the entrance of first-generation Ethiopian immigrants in this occupation since the 1980s. This research demonstrates that mixed embeddedness or the interplay of structural factors such as blocked mobility as well as cultural factors such as the strong social networks that exist among Ethiopian immigrants were important in the induction of new immigrants into taxicab driving. The demographic composition of the Washington metropolitan area and policies of the DC Taxicab Commission that allow for fairly easy entry of new drivers in the taxicab business also facilitated the emergence of this occupational niche.  相似文献

Terrorist organizations’ physical safe havens continue to shape the terrorist threat to the United States by extending the groups’ longevity and increasing the threat they pose. As a result, eliminating terrorist safe havens has been a key component of U.S. counterterrorism policy since at least 2001. However, some scholars challenged the post-9/11 policy consensus that terrorists find sanctuary in weak states and so-called ungoverned spaces. This article seeks to bridge this gap between scholarship and policy by offering a typology for disaggregating different kinds of terrorist safe havens. Our typology operates on two axes based on host government will (i.e., the host government's posture toward each group with haven inside its borders), as well as government capability, (specifically whether the host government possesses the specific capabilities needed to oust each group). This intersection of will and capability produces three types of havens. We briefly illustrate each type of haven using the exemplar case study of Pakistan—a location often described as an overarching safe haven, but which is actually home to several sanctuaries—and offer policy recommendations for addressing them. A need exists to disaggregate and identify how the United States can approach haven elimination. This typology and the analysis that stems from it offer a starting point for devising such strategies.  相似文献

ABSTRACT

Outcome based policies promote the use performance accountability models. However, the impact these policies have on the ethical culture of public sector organizations has not been adequately assessed. This research examines performance accountability reforms by examining the City of Atlanta’s implementation of federal and state performance policies. The analysis reveals the use of performance models in vulnerable organizations negatively impact employees’ ethical behavior. Teachers and administrators altered test results, delivered threats, misled parents and students about performance outcomes, and were dishonest with state investigators to give the illusion that performance goals had been met or exceeded.  相似文献

The Journal of Political Science Education (JPSE) provides over a decade of research on political science pedagogy, featuring empirical research documenting best practices in the field. This article provides an overview of JPSE-published research on the topics of civic education and engagement. It summarizes the number and scope of articles on this topic and highlights key findings from the journal’s first 12 years. This comprehensive overview of past research is designed to facilitate high quality future research. A detailed exploration of past research provides a useful “jump start” for teacher-scholars eager to advance the scholarship and pedagogy of engagement.  相似文献

This paper adds to our understandings of women’s post-separation experiences of coercive control through the introduction of a new concept—custody stalking. It is defined as a malevolent course of conduct involving fathers’ use of custody and/or child protection proceedings to overturn historic patterns of care for children. The experience of custody stalking is explored through three composite narratives derived from twelve mothers who participated in an exploratory, qualitative study on the involuntary loss of maternal care time following separation. The losses suffered caused these mothers tremendous grief, damaged their psychological wellbeing and had a detrimental effect on their mothering relationships. Yet custody stalking, as a form of malevolent attack, is not well recognised and mothers’ resultant losses are largely culturally invisible. This is in marked contrast to paternal filicides, another form of post-separation avenging attack committed by some fathers that also leads to maternal loss experiences, albeit more absolute.  相似文献

Witnessing inter-parental intimate partner violence has been found to be associated with adolescents’ own relationship abuse. This study investigates the relationship between patterns of inter-parental intimate partner verbal and physical violence victimization reported by parents and their children’s reports of dating abuse experiences and behavior. Latent class analysis was performed on a sample of 610 parents (42% male and 67% white) and their dating adolescent children (ages 12–21 years; 52% male). Parents reported five types of victimization by their partners in the past year, while youth concurrently reported their own victimization and perpetration within their dating relationships. Three profiles of parents’ intimate partner victimization were related to youth relationship abuse experiences and behaviors. Children of parents who experienced verbal abuse were more likely to experience similar patterns in their own relationships, whereas children of parents who report physical and verbal abuse were more likely to report psychological, physical and sexual abusive encounters in their partnerships. Findings indicate that parents’ relationship quality and abusive behaviors may have a long lasting effect on their children as they enter mid and late adolescence. Parents should pay attention to their own relationship quality and behavior even as their teen-age children gain independence.  相似文献

This paper starts with a flood in southern Malawi. Although apparently a ‘natural’ event, those most affected argued that it was made much worse by the rehabilitation of a nearby irrigation scheme. We use this example to interrogate the current interest in resilience from a perspective informed by political ecology and political economy, arguing that a focus on resilience should not be at the expense of understanding the conditions that shape vulnerability, including the ways in which ‘communities’ are differentiated. Complex factors are at play – and the ways in which these combine can result in a ‘perfect storm’ for some individuals and households. These factors include the effects of history combining with ethnicity, of legitimacy influencing voice, and of the interplay of political dynamics at different levels. In particular, processes of commodification have played an important role in shaping how some may benefit at the cost of catastrophic harm to others.  相似文献

Fibromuscular dysplasia is an idiopathic, nonatheromatous, and noninflammatory arterial disease that most commonly affects the renal and carotid arteries. We report a child with subarachnoid and ocular hemorrhage associated with an aneurysm due to fibromuscular dysplasia. Computed tomography following a witnessed collapse revealed diffuse subarachnoid hemorrhage and severe cerebral edema. An autopsy confirmed the radiographic findings and detected bilateral retinal hemorrhages, optic nerve sheath hemorrhages, and a ruptured saccular aneurysm due to focal fibromuscular dysplasia involving the intracranial right vertebral artery. This case documents a fatal subarachnoid hemorrhage in a child with an intracranial saccular aneurysm caused by fibromuscular dysplasia. The associated retinal hemorrhages are easily detected by postmortem monocular indirect ophthalmoscopy.  相似文献
