We report the case of a middle‐aged man, without medical history, who suddenly died at his workplace. The autopsy highlighted a pathological heart macroscopically, with multiple small white areas on the left myocardium. Coronary dissection revealed a pseudotumoural fibromyxoid aspect within the anterior interventricular artery (AIVA) and the left main coronary trunk, including reduction in their diameter with tight stenosis. Microscopic examination of these arteries showed fibroinflammatory wall destruction. In the left myocardium, there were multiple focal ischemic areas at different stages of recovery. Our case is an illustration of primary ischemic heart disease due to coronary arteritis, with a pseudotumoural presentation, which was revealed by sudden death. We discuss the cause of death and the etiological diagnosis preceding coronary arteritis.  相似文献

How does a configuration of policing work regardless of the differences among its constituent members, who may relate to various social fields and range from for-profit organizations to law-enforcement and other state agencies? The article aims at providing some of the answers to this critical question in the light of financial policing, at the interface between the fields of finance and security. With the emphasis on money laundering and terrorist financing, financial policing resonates with other policing configurations that are ‘partly detached from the institutions of the police and start referring to a more general associative practice of assembling risk knowledge, technologies and agencies into networks that govern through rendering and distributing risks’ (Huysmans 2014). The paper argues that everyday financial policing is based on a misunderstanding, as both its current condition of possibility and the fundamental structure of communication between the involved parties. This focus on misunderstanding contributes to question traditional interpretations of (national and/or international) partnership against policing-related public problems. To help understand the paradoxical and controversial productivity of misunderstanding as a sine qua non condition of policing, the article draws on a transatlantic perspective with empirical research in the European Union Institutions, the United Kingdom and Canada.  相似文献

Citizens’ attitudes toward the death penalty have been effected by the availability of life without parole (LWOP). Our analysis focuses upon data from a representative sample of Kentuckians on death penalty attitudes. The factors influencing and related to death penalty support and compared to support for LWOP are considered along with a review of Kentucky survey findings from 1989–2016. The results reveal consistent support for LWOP over the death penalty. Male Kentucky residents with a college education were most likely to support life without parole over capital punishment while male conservatives did not.  相似文献

Community-oriented social capital strategies and punitive-oriented policing approaches conflict. Establishing local networking initiatives with community-oriented policing at the centre lends itself to an assets-based policing approach, based on honouring, mobilizing and extending the assets of community members. Scholars argue about the need for comparative research on convergences and divergencies across subcultures on the streets and communities. Based on qualitative data gathered from working class communities in Scotland and Denmark in 2014, the article draws inspiration from community-generated theory of social capital to explore the micro-sociology of experiences and understandings about community–police integration policy initiatives. We use this perspective to argue that the building of positive inter-generational and police–community relationships is the result of social exchanges and officers’ use of what we call ‘constructive investment strategies’. Ironically, our insights from Scotland to Denmark also suggest what appear as positive achievements of community policing may instead intensify residents’ negative perceptions of police officers and organizations. In this way, the article illuminates the tangled and conflicted nature of these embedded symbolic interactions, social capital formations and the latter’s form as a potential positional and ‘tribal’ commodity.  相似文献

This article argues that Amtrak's design as a “quasi-public, for-profit” corporation was seriously flawed from its beginnings. The corporation was isolated from America's private railroads, and isolated from trust-funding financial mechanisms that supported highways, airports, and mass transit. It depended on powerful Democratic congressional patrons and labor union support for protection from Republican executive budget cuts. But these allies pushed Amtrak into running far more costly service than was good for its bottom line. The corporation was already engaged in an internal reorganization designed to bring it closer to its customers, when the Republican victory in the 1994 congressional election launched an external effort to reorient and restructure Amtrak. There are three possible outcomes of the two-sided reinvention process: status quo and continued slow decline; partnership based on new relationships between Amtrak, federal and state governments, and the private sector; and privatization which might still require substantial public expenditures for some time. Synchronizing the opportunities created by both the internal and the external reinvention efforts is the key to whether Amtrak can emerge as a viable and valuable provider of rail transportation in the 21st century.  相似文献

Dating in adolescence plays an integral part in the development of sexual and social identities. This process is particularly salient for sexual minority youth who face additional obstacles to their identity formation due to their marginalized status. We investigated the influence of participating in a same-sex relationship (SSR) or an opposite-sex relationship (OSR) on sexual minority youths’ psychological well-being (i.e., symptoms of depression, anxiety and internalized homophobia, and self-esteem) in an ethnically-diverse sample of 350 youth (55% male) between the ages of 15–19 years, recruited from three GLBT drop-in centers in the New York City area. Using longitudinal data, we examined youths’ SSR and OSR over time. Multivariate regression analyses suggest that involvement in a SSR was positively associated with changes in self-esteem in males, and negatively correlated with changes in internalized homophobia in females. We discuss the implications for positive development in sexual minority adolescent populations.  相似文献

The stages/policy cycle, multiple streams, and Advocacy Coalition Framework (ACF) approaches to understanding policy processes, all have analytical value although also attracting substantive criticism. An obvious direction for research is to determine whether the multiple streams framework and the ACF can be refined and applied to other dimensions of policy‐making set out in the policy cycle model. This article argues that extending and modifying Kingdon's framework beyond the agenda‐setting stage is best suited to this endeavour. Doing so makes it possible to bring these three approaches into alignment and enhances our understanding, although retaining the core insights of each.  相似文献

Abstract

Theology in four voices represents a fitting methodological model for the study of political ideology, given the similarities between religions and ideologies as belief systems with ineliminable, fundamental beliefs. The formal theological voice is dropped from consideration on the grounds that, while the involvement of academic theologians in the theology of ordinary believers is entirely appropriate, political theorists ought not to be involved in seeking to change or refine the ideologies which they research. The normative voice – which we refer to as the established voice – consists of texts which carry authority within a particular ideology, such as The Communist Manifesto in Marxism, or J.S. Mill’s On Liberty in liberalism; the espoused voice represents that which adherents of an ideology explain about what they believe; the operant voice consists of the political action taken by the adherents. While there are potential disadvantages to this method, there are also potential advantages. Firstly, it enables a fuller understanding of an ideology, especially when tensions arise between the three voices. Secondly, it allows the researcher to enter at any one of three points into a circle leading from pre-understanding to understanding. Thirdly and finally, the model presents opportunities to combine different methodological approaches into ideological research.  相似文献

To develop and refine interventions to prevent youth suicide, knowledge is needed about specific processes that reduce risk at a population level. Using a cross-sectional design, the present study tested hypotheses regarding associations between self-reported suicide attempts, emotion regulation difficulties, and positive youth–adult relationships among 7,978 high-school students (48.6 % male, 49.9 % female) in 30 high schools from predominantly rural, low-income communities. 683 students (8.6 %) reported a past-year suicide attempt. Emotion regulation difficulties and a lack of trusted adults at home and school were associated with increased risk for making a past-year suicide attempt, above and beyond the effects of depressive symptoms and demographic factors. The association between emotion regulation difficulties and suicide attempts was modestly lower among students who perceived themselves as having higher levels of trusted adults in the family, consistent with a protective effect. Having a trusted adult in the community (outside of school and family) was associated with fewer suicide attempts in models that controlled only for demographic covariates, but not when taking symptoms of depression into account. These findings point to adolescent emotion regulation and relationships with trusted adults as complementary targets for suicide prevention that merit further intervention studies. Reaching these targets in a broad population of adolescents will require new delivery systems and “option rich” (OR) intervention designs.  相似文献

This article discusses the life of Ann Jebb (1735–1812) in light of recent scholarship on gender and politics in late eighteenth‐century Britain. Wife of the Unitarian political activist John Jebb, Ann was one of the most respected women among ‘enlightened’ Rational Dissenters. In the 1770s at Cambridge, and afterwards in London, she held ‘tea parties’ for reformers, and wrote pamphlets and newspaper articles supporting religious, educational and political reform. Her case sheds light on the activities and status of women in reform circles during the ‘age of cultural revolution’, and further complicates the separate spheres model of gender in the late eighteenth century.  相似文献
