This article provides the first analysis of gendered promotion issues for cabinet ministers using most-similar systems design for three “Westminster-style” governments: Australia, Canada, and New Zealand. Using individual-level data and controlling for biographical, institutional, and country effects we find, in common with earlier literature, that women are more likely to be given less prestigious cabinet posts and be assigned to “feminine” portfolio. Using both sequence and event history analysis, we see the careers of men and women starkly diverge. We find that women are less likely to be promoted than men but find no relationship between prestigious portfolio and promotion. However, feminine portfolio assignments decrease the promotion prospects for women yet increase them for men.  相似文献

In the past two decades, the Journal of Public Affairs has solidified corporate public affairs as a legitimate leadership skillset vital to driving future business growth. Yet, more work at a persistently overlooked gap in the Journal, the intersection of public affairs and family businesses, might shed new light on thriving, trusted, and sustainable business practices. This paper examines the unique contributions of family businesses as trusted influencers. As one of the most prominent forms of business, worldwide, family businesses persistently enjoy unusually high levels of public trust while collectively employing millions of wage earners yet their contributions to corporate external affairs research ostensibly have been largely overlooked. These “silent” community and social influencers offer a potentially new perspective on effective public outreach given their persistent and unique trust advantage. Family business' trust-based capabilities can potentially bring new insights to understanding effective stakeholder engagement, credible communications, and issues management—the sweet spot of corporate public affairs functions. Future research opportunities based on relational- and locational- advantages of trusted family businesses are identified.  相似文献

Children experiencing parental incarceration face numerous additional disadvantages, but researchers have often relied on these other co‐occurring factors primarily as controls. In this article, we focus on the intimate links between crime and incarceration, as well as on the broader family context within which parental incarceration often unfolds. Thus, parents’ drug use and criminal behavior that precedes and may follow incarceration periods may be ongoing stressors that directly affect child well‐being. We also use our analyses to foreground mechanisms associated with social learning theories, including observations and communications that increase the child's risk for criminal involvement and other problem outcomes. These related family experiences often channel the child's own developing network ties (peers, romantic partners) that then serve as proximal influences. We explore these processes by drawing on qualitative and quantitative data from a study of the lives of a sample of respondents followed from adolescence to young adulthood, as well as on records searches of parents’ incarceration histories. Through our analyses, we find evidence that 1) some effects attributed to parental incarceration likely connect to unmeasured features of the broader family context, and b) together parental incarceration and the broader climate often constitute a tightly coupled package of family‐related risks linked to intergenerational continuities in criminal behavior and other forms of social disadvantage.  相似文献

Recently, a sample containing cyclopropylfentanyl was analyzed at this laboratory. Cyclopropylfentanyl began to appear in the United States' illicit drug markets in 2017. Unfortunately, cyclopropylfentanyl presents an analytical challenge due to its mass spectrum being almost identical to that of crotonylfentanyl. There are two possible isomers of crotonylfentanyl, Z- and E- crotonylfentanyl. In order to provide sufficient analytical data to distinguish the two isomers of crotonylfentanyl and cyclopropylfentanyl, crotonylfentanyl was synthesized and fully characterized. Each isomer was analyzed via nuclear magnetic resonance spectroscopy, gas chromatography–mass spectrometry, and Fourier transform infrared spectroscopy. During the synthesis of crotonylfentanyl, an unknown compound was formed. The identification of this compound and the analytical characterization of the two isomers of crotonylfentanyl are presented. Through the comparison of these compounds, it was confirmed that cyclopropylfentanyl can be differentiated from crotonylfentanyl.  相似文献

This study will discuss trends in suicide data compiled over 10 years in Dutchess County, NY, from 2004 to 2013. These data were based on reporting and examination standards recommended by the National Association of Medical Examiners and Department of Justice death investigation standards. Almost 300 cases were analyzed in terms of the deceased's gender, age, race, method of suicide, and weapon used. Results from this study agree with other reports showing significant differences for method of death both in terms of age and gender, with men more likely to choose firearms and women more likely to choose overdose. Furthermore, older persons were more likely to commit suicide by firearms, and the younger persons were more likely to commit suicide by overdose. However, other areas, such as method of suicide, differ from national statistics.  相似文献

Plagiarism in the context of the law is a highly nuanced and complex concept, involving consideration of academic integrity and disciplinary rules and assessments of intent, which colour the responses of both universities and courts when confronted by the misuse of others’ words and ideas without appropriate referencing. Within academia, plagiarism is treated as ‘a capital offence’. In the context of admission as a lawyer, professional admissions boards in Australia use findings of major plagiarism at university as a reason for denying or delaying admission to practice on two grounds: firstly, if it amounts to cheating per se, as being indicative of a character flaw inconsistent with the character requirements of officers of the court; and secondly on the related basis that it is (or is assumed to be) a reliable predictor of future professional misconduct. Given this, Australian universities must educate students about academic integrity and referencing (particularly in the digital age, where sources and opportunities for misconduct are escalating), provide law students with training and practice in appropriate use of others’ material, and provide relevant information to students about the implications of findings of misconduct being made against them. This is important because, while there is a widespread perception that plagiarism ceases to be a consideration after admission as a lawyer, this is not supported by the decided cases.  相似文献

Systems change efforts seek to alter the status quo by shifting the form and function of a targeted system. Evaluation is a critical component, yet little research has examined a collaborative forum as a vehicle for change in the criminal justice system. Over 150 citizens and police were brought together to work collaboratively at improving a Canadian police complaints system. Using survey, participant observation, and focus group data, this study investigates the perceptions of this Forum as a vehicle for systems change in police oversight mechanisms. We find the Forum provided both opportunities for, and barriers to, collaborative systems change work. However, these findings need to be understood within the context of police-community relations as fear and mistrust of police influence problem definitions and potential solutions. Therefore, the collaboratives model is not a one-size-fits-all approach to systems change work in the criminal justice system.  相似文献

A particular source of anxiety for many immigrants is personal safety. This study examines the levels and correlates of perceived risk of crime among two understudied immigrant groups, Arab and Chinese immigrants, who resided in an understudied geographic area, the Detroit metropolitan area. Results suggested several universal and immigrants-specific correlates that are significant predictors of Arab and/or Chinese immigrants' perceptions of crime, including self-defense ability, police effectiveness, neighborhood collective efficacy, language proficiency, expectation of U.S. crime condition prior to arrival, and perception of home society crime. Implications for future research are discussed.  相似文献
