The post-migration sexual citizenship of Latino gay men in Canada

The Cuéntame! study interviewed 25 Spanish-speaking gay and bisexual men in Toronto. Their migration experiences are traversed by economic rationales, security concerns and the embodied experiences of race, gender, culture and sexuality. Most express narratives of empowered opportunity in distancing themselves from restrictive sexual regimes of their place of origin, but at the same time, many migrants trade a new sense of social acceptance as gay for marginalized statuses defined by diminished social and economic capital. The social participatory rights of citizenship are particularly affected by sexuality and social class. The need and desire to establish social and sexual connections in a new environment often characterized by economic vulnerability shape experiences of social capital and citizenship rights.     

The effect of sodium fluoride on the stability of cyanide in postmortem blood samples from fire victims

Assigning a level of significance to cyanide concentrations found in the blood of fire victims is often hampered by the fact that cyanide is inherently unstable in cadavers and in stored blood samples. A few researchers have proposed that sodium fluoride can be used to minimize the instability of cyanide in blood samples; however, controlled studies have not been performed to support validation of this hypothesis. To test the sodium fluoride hypothesis, both treated and control blood samples from 14 autopsied fire victims were tested over a 25-30 day period. A 2% concentration of sodium fluoride was added to the blood samples at the start of testing and the samples were refrigerated between testing intervals. Cyanide concentrations in the treated and control samples were measured between 9 and 11 days post treatment and between 25 and 30 days post treatment. A statistically significant difference was not present between blood cyanide concentrations in treated and control samples between 9 and 11 days. During this time period, although there were small statistically significant increases in both treated and untreated samples the fluctuations were minor. Since the treated and control samples did not exhibit instability between 9 and 11 days, it is not surprising that the sodium fluoride appeared to have no effect. However, a statistically significant difference between blood cyanide concentrations in treated and control samples was observed between 25 and 30 days. Those samples treated with sodium fluoride showed a reduction in blood cyanide variability with virtually no overall change, over a 25-30 day period when compared to control samples, while unconditioned samples showed a significant, average increase of 35%. Based on the findings of this study, it is recommended that 2% sodium fluoride be added to blood samples obtained from fire victims to reduce cyanide instability due to bacteriological activity.     

Carbon Taxation and Policy Labeling: Experience from American States and Canadian Provinces

A vast economics literature embraces taxation of the carbon content of fossil fuels as the superior policy approach for reducing greenhouse gas emissions. However, experience around the world suggests that carbon taxes face exceedingly difficult political hurdles. Federal experience in the United States and in Canada confirms this pattern. This article reviews sub‐federal policy development among American states and Canadian provinces, a great many of which have pursued climate policy development. With one major exception, explicit carbon taxation appears to remain a political nonstarter. At the same time, states and provinces have been placing indirect carbon prices on fossil fuel use through a wide range of policies. These tend to strategically alter labeling, avoiding the terms of “tax” and “carbon” in imposing costs. The article offers a framework for considering such strategies and examines common design features, including direct linkage between cost imposition and fund usage to build political support.     

Evaluation of pediatric skull fracture imaging techniques

Radiologic imaging is crucial in the diagnosis of skull fracture, but there is some doubt as to whether different imaging modalities can accurately identify fractures present on a human skull. While studies have been performed to evaluate the efficacy of radiologic imaging at other anatomical locations, there have been no systematic studies comparing various CT techniques, including high resolution imaging with and without 3D reconstructions to conventional radiologic imaging in children, we investigated which imaging modalities: high-resolution CT scan with 3D projections, clinical-resolution CT scans or X-rays, best showed fracture occurrence in a pediatric human cadaver skull by having an expert pediatric radiologist examine radiologic images from fractured skulls. The skulls used were taken from pediatric cadavers ranging in age from 5 months to 16 years. We evaluated the sensitivity and specificity for the imaging modalities using dissection findings as the gold standard. We found that high-resolution CT scans with 3D projections and conventional CT provided the most accurate fracture diagnosis (single-fracture sensitivity of 71%) followed by X-rays (single-fracture sensitivity of 63%). Linear fractures outsider the region of the sutures were more identifiable than diastatic fractures, though the incidence of false positives was greater for linear fractures. In the two cases where multiple fractures were present on the same anatomical skull location, the radiologist was less likely to identify the presence of additional fractures than a single fracture. Overall, the high-resolution and clinical-resolution CT scans had the similar accuracy for detecting skull fractures while the use of the X-ray was both less accurate and had a lower specificity.     

资本主义与新兴世界秩序

西方长达两个世纪之久的霸权正在走向终结,曾经推动西方崛起的现代化革命,如今已惠及所有国家。因此,19世纪发展起来并为中心——边缘世界秩序（core-periphery international order）奠定了基础的国家间实力差距（power gap）正在缩小。这一变化带来的结果是世界由有中心的全球体系（centred globalism）向去中心的全球体系（decentred globalism）转变。与此同时,当权力变得越来越分散的同时,主要国家之间意识形态上的分歧程度也正在缩小。事实上,当代世界中所有大国在某种形式上走的都是资本主义道路,在兴起中的世界新秩序中,意识形态上的差异比它在过去一个世纪里所呈现的要小得多。问题是：意识形态上的相对同质性是否将在四种主要的资本主义国家治理类型（自由民主主义体制、社会民主主义体制、竞争性威权主义体制和国家官僚主义体制）中引起地缘经济或者地缘政治上的竞争？民主主义与威权主义类型的资本主义之间政治上的分歧是否会超越它们之间的共同利益？还是它们之间存在的共同利益消弭了彼此的分歧？当代世界会出现像20世纪初那种不同类型而互为冲突的资本主义模式吗？或者会产生某种形式的“协和资本主义”？在未来一段时间里,我们很有可能仍然会处在一个政治上分化的多种类型的资本主义世界。由此,对于决策者来说所面临的重要任务就是要确保地缘经济竞争将不会导致地缘政治冲突的发生。     

Twentieth Century Benchmark Dates inInternational Relations:The Three World Wars in Historical Perspective *

This paper builds on the author’s earlier work on benchmark dates inInternational Relations. The Introduction summarises this work and explains howthis paper extends the analysis from suggestions made, but not developed, in earlierpublications. The second section looks in detail at 20 th century benchmark dates centredon the three world wars (First, Second and Cold). It argues that the changes clusteredaround the Second World War are both deeper and more extensive than those clusteredaround either the First World War or the Cold War. The third section uses theseinsights to open-up a macro-historical perspective on the 20 th century, demonstratingthe ways in which choices in relation to both time and scale affect the constructionof macro-historical perspectives. The fourth section demonstrates the advantages ofa two-century perspective on the 20 th century. Here, and in the conclusion, we arguethat the key issues that underpinned world politics in the 20 th century are best seen asthe downstream consequences of the dynamics and challenges ushered in by the 19 thcentury “global transformation.”     

Adoption Support and the Negotiation of Ambivalence in Family Policy and Children's Services

In this paper ambivalent commitments to parenting and family life by the New Labour government are explored by reference to the example of adoption support. Developments in adoption illuminate contrasting expectations in family policy and children's services more generally. Traditional normative concerns to support family status and parental autonomy are unsettled by contemporary anxieties about child outcomes and social mobility. Impatience with the attitudes and behaviour of parents has led to a 'progressive universalism' in which enhanced parenting services and expectations for all are combined with increasingly insistent and targeted interventions for the particularly needy, reluctant or recalcitrant few. At the same time demands for greater service modernization and professional effectiveness have led government to position parents as (potential) consumers too. The paper discusses these policy and practice tensions and concludes that new spaces are being opened up for the negotiation between parents and professionals about rights and responsibilities in family life and its support.     

Alternatives to NIMBY gridlock: voluntary approaches to radioactive waste facility siting in Canada and the United States

Abstract: Neither Canada nor the United States has sited a new radioactive waste management facility in more than two decades, despite the continuous generation of new waste and the paucity of reliable disposal capacity. Both nations have stirred up considerable political controversy in attempting to site such facilities, with aggressive local collective action consistently blocking proposals. Building on provincial experience in gaining public support for hazardous waste facility siting tlirough a voluntary, comprehensive process, both Ontario and Nebraska Show signs of devi?ting from the classic Not-in-My-Back-Yard (NIMBY) response for low-level radioactive waste. Through a variation of the process used successfully in Alberta and Manitoba for hazardous waste, Ontario and Nebraska have demonstrated the potential applicability of these alternative siting principles for radioactive waste. Sommaire: Ni le Canada, ni les États-Unis n'ont construit de nouvelles installations de gestion des déchets radioactifs depuis plus de deux décennies, malgré la production continuelie de déchets supplémentaires et malgré la faible capacité d'élimination fiable. Les deux nations ont déclenché des controverses politiques considérables en essayant de mettre en place de telles installations, et leurs propositions ont été bloquées systématiquement et agressivement par les collectivités locales. Forts de certaines expériences provinciales pour gagner le soutien du public ewers l'emplacement d'une installation de déchets dangereux grâce à un processus volontaire et extensif, l'Ontario et le Nebraska semblent dévier de la réaction classique “ pas dans ma cour ” en ce qui concerne les déchets faiblement radioactifs. Par l'entremise d'une variante du processus utilisé avec succès pour les déchets dnngereux en Alberta et au Manitoba, l'Ontario et le Nebraska ont démontré qu'on pourrait éventuellement appliqucr ces principes de rechanpe pour l'emplacement des installations traitant les déchets radioactifs.
