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.     

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.
