The following is an exchange concerning the concept of ‘illiberal moderates’ and its implications for a new global architecture as well as for a worldview that sees the evolution of a global core of shared values which favour domestic and international security, in sharp contrast to the ‘clash of civilizations’ thesis. The original statement was published in the Cambridge Review of International Affairs (Etzioni 2006). A more extensive treatment can be found in Part III of Security first: for a muscular, moral foreign policy (Etzioni 2007b), which examines texts of four religious and two secular belief systems as well as review of relevant public opinion polls and ‘traveller notes’. Here follows a brief summary of the main thesis, followed by comments from prominent scholars and Etzioni's response to these comments.  相似文献

The French social critic and lapsed sociologist Jean Baudrillard, who died in 2007, is author of the highly acclaimed America and Cool Memories . One of the more poignant observers of America since his compatriot Alexis de Tocqueville roamed these lands, Baudrillard's insights, in the manner of the parochial universalism of Parisian post-Marxist intellectuals, dazzle some-where between the brilliant and impenetrable. Back in 1990, I sat down with him in the haute tacky Royal Palace motel in Los Angeles, which Baudrillard claimed was his favorite city. For him, LA was the closest thing to a center in this heterogeneous, ex-centric world.  相似文献

This essay examines the risks of racialized science as revealed in the American mustard gas experiments of World War II. In a climate of contested beliefs over the existence and meanings of racial differences, medical researchers examined the bodies of Japanese American, African American, and Puerto Rican soldiers for evidence of how they differed from whites.  相似文献

There are a number of forensic cases in which the identification of the epithelial cell type from which DNA originated would provide important probative evidence. This study aimed to develop a technique using histological staining of fixed cells to distinguish between skin, buccal and vaginal epithelium. First, 11 different stains were screened on formalin-fixed, wax-embedded cells from five women. Samples were analysed qualitatively by examining staining patterns (colour) and morphology (absence or presence of nuclei). Three of the staining methods – Dane's, Csaba's and Ayoub-Shklar – were successful in distinguishing skin epithelial cells from buccal and vaginal. Second, cells were smeared directly onto slides, fixed with one of five fixatives and stained with one of the three stains mentioned above. Methanol fixation, coupled with the Dane's staining method, specific to keratin, was the only technique that distinguished between all three cell types. Skin cells stained magenta, red and orange and lacked nuclei; buccal cells stained predominantly orange–pink with red nuclei; while vaginal cells stained bright orange with orange nuclei and a blue extracellular hue. This staining pattern in vaginal cells was consistent in samples collected from 50 women aged between 18 and 67. Identification of cell type from unlabelled micrographs by 10 trained observers showed a mean success rate of 95%. The results of this study demonstrate that histological staining may provide forensic scientists with a technique for distinguishing between skin, buccal and vaginal epithelial cells and thus would enable more conclusive analyses when investigating sexual assault cases.  相似文献

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.  相似文献

In Ashley v Chief Constable of Sussex , the House of Lords ruled that a civil claim in trespass to the person may be sustained against an individual police officer in respect of a fatal shooting, in circumstances where the officer had already been acquitted in criminal proceedings and where liability to compensate in respect of all losses had been conceded. Two members of the majority clearly ruled that trespass torts may have a vindicatory purpose which survives a concession of liability to compensate, thus deepening the connection between tort, and the protection of fundamental rights, and suggesting an intriguing distinction between the functions of civil and criminal law.  相似文献

Abstract: Drawing on a longitudinal study from the early years of implementation of health‐care networks in Quebec, this article describes how public‐sector managers deal with complex challenges when both organizational structures and organizational strategies are radically transformed simultaneously. The new organizations studied had to completely re‐shuffle roles and responsibilities of their management teams while making sense of their new mandate of developing a population‐focused approach to health problems – all the time maintaining day‐to‐day operations. The four health‐care networks studied proceeded somewhat differently to meet these reciprocal challenges. The study reveals the importance of balancing organizing initiatives (focused on structures) with “sense‐making” initiatives (focused on strategies), of developing capacities for sense‐making through the creation of key “sense‐maker/sense‐giver” positions whose occupants are able to ensure that conceptual activities engage people working at different levels, even as organizational structures are in flux, and of mobilizing external constraints and influences as opportunities and resources in sense‐making and organizing. Sommaire : Se fondant sur une étude longitudinale des premières années de la mise en œuvre des réseaux de soins de santé au Québec, cet article décrit la manière dont les gestionnaires du secteur public font face à des défis complexes, alors que les structures et les stratégies organisationnelles sont radicalement transformées simultanément. Les nouveaux organismes étudiés ont dû complètement remanier les rôles et les responsabilités de leurs équipes de gestion et comprendre leur nouveau mandat d'élaborer une approche axée sur la population pour ce qui est des problèmes de santé, tout en maintenant leurs activités au jour le jour. Les quatre réseaux de soins de santéétudiés ont travailléà relever ces défis réciproques d'une manière assez différente. L'étude révèle l'importance de trouver un équilibre entre les initiatives consistant à organiser (axées sur les structures) et les initiatives consistant à interpréter les faits (axées sur les stratégies) ; de perfectionner les capacités à interpréter les faits grâce à la création de postes clés d'«interpréteurs de faits», dont les titulaires veilleraient à ce que des activités conceptuelles fassent intervenir les gens travaillant à différents niveaux même lorsque les structures organisationnelles fluctuent continuellement; et enfin de tirer parti des contraintes et influences externes comme autant d'occasions et de ressources pour interpréter et organiser les faits.  相似文献

In an effort to take positive steps toward coping with problems for families and children created by high levels of separation and divorce, ever increasing civil caseloads and the exposure of children to interparental conflict, court‐affiliated educational programs have emerged in the United States for parents separating from their spouse or partner or going through a divorce. This article will provide an overview of the creation of such programs and their development, which includes a discussion regarding the numerous states currently mandating parents to attend. It will summarize some of the research which has been conducted as to the efficacy of the programs and will provide the results of our nationwide research for each state's parent education status. There is a discussion of domestic violence issues and sensitivities in the context of parent education programs and possible future directions for mandatory parent education.  相似文献
