The Bully-Sexual Violence Pathway theory has indicated that bullying perpetration predicts sexual violence perpetration among males and females over time in middle school, and that homophobic name-calling perpetration moderates that association among males. In this study, the Bully-Sexual Violence Pathway theory was tested across early to late adolescence. Participants included 3549 students from four Midwestern middle schools and six high schools. Surveys were administered across six time points from Spring 2008 to Spring 2013. At baseline, the sample was 32.2% White, 46.2% African American, 5.4% Hispanic, and 10.2% other. The sample was 50.2% female. The findings reveal that late middle school homophobic name-calling perpetration increased the odds of perpetrating sexual violence in high school among early middle school bullying male and female perpetrators, while homophobic name-calling victimization decreased the odds of high school sexual violence perpetration among females. The prevention of bullying and homophobic name-calling in middle school may prevent later sexual violence perpetration. 相似文献

This paper investigates the interplay between the Social Cash Transfer Programme (SCTP) and the Farm Input Subsidy Programme (FISP) in Malawi. We take advantage of data collected from a 17-month evaluation of a sample of households eligible to receive SCTP, which also provided information about inclusion into FISP. We estimate two types of synergies: i) the complementarity between SCTP and FISP, that is whether the impact of both interventions run together is larger than the sum of the impacts of these interventions when run separately, and ii) the incremental impact of receiving FISP when a household already receives SCTP, as well as the incremental impact of receiving SCTP when a household already receives FISP. The analysis shows that there are synergies between the two policy interventions, mainly in terms of incremental impacts of each programme over the other, in increasing expenditure, agricultural production and livestock. 相似文献

Scholars of representative bureaucracy have long been interested in the linkage between passive representation in public agencies and the pursuit of specific policies designed to benefit minority groups. Research in this area suggests that the structural characteristics of those organizations, the external political environment, and the perceptions of individual bureaucrats each help to facilitate that relationship. Work to date has not, however, sufficiently investigated the impact of region on representation behavior, which is surprising given the emphasis that it receives in the broader literature on race and politics. Drawing on that literature, this study argues that, for black bureaucrats, region of residence is an important moderator of active representation because it helps to determine the salience of race as an issue and the degree of identification with racial group interests. It tests hypotheses related to that general argument in a nationally representative sample of more than 3,000 public schools. The results suggest that black teachers produce greater benefits for black students in the South, relative to other regions. A supplementary analysis also confirms the theoretical supposition that race is a more salient issue for Southern black bureaucrats, when compared with their non-Southern counterparts. 相似文献

The intentional withholding of critical work‐related information can have serious negative consequences in public organizations. Yet, few studies have examined why public employees intentionally remain silent about problems and how to prevent such behaviour. This article provides insights into how managers may lower employee silence in government organizations. We develop a model that suggests that empowering leadership by frontline supervisors reduces public employee silence, by improving employee trust in their supervisors, granting employees control over their jobs, and strengthening identification with the organization. We test the model in two cross‐sectional studies with data collected from all employees working in two local governments in the United States. We find empirical support for the model in both studies. We discuss the implications of the research results for public management scholarship and practice. 相似文献

ABSTRACTAlthough India’s cotton sector has been penetrated by various input- and capital-intensive methods, penetration by herbicide has been largely stymied. In Telangana State, the main obstacle has been the practice of ‘double-lining’, in which cotton plants are spaced widely to allow weeding by ox-plow. Path dependency theory primarily explains the persistence of sub-optimal practices, but double-lining is an example of an advantageous path for cash-poor farmers. However, it is being actively undermined by parties intent on expanding herbicide markets and opening a niche for next-generation genetically modified cotton. We use the case to explicate the role of treadmills in technology ‘lock-in’. We also examine how an adaptive locked-in path may be broken by external interests, drawing on recent analyses of ‘didactic’ learning by farmers. 相似文献
