Global value chains and regimes of urban governance: A comparison of four Canadian gateway cities

Gateway cities are connected systems of transportation infrastructure that support the insertion of the urban region in international production, distribution and consumption networks. In this article, we propose a framework through which to grasp how the governance of gateway cities shapes their physical positioning in global value chains. We argue that specific urban governance configurations are best understood through the dynamic relationships between global economic requirements, local infrastructure assets, institutional arrangements, and the communities directly implicated. We put urban regimes, which are composed of urban coalitions of public and private actors acting at a variety of scales, and their sets of goals and norms, at the centre of these configurations. Focusing on the case of four Canadian city-regions, we use this framework to compare the ways in which the governance of these gateway cities occurs as it pertains to the development of physical infrastructure in support of international trade and global value chains.Les villes-seuils constituent des systèmes d’infrastructure de transport qui permettent l’intégration de régions spécifiques aux réseaux internationaux de distribution, de production et de consommation. Dans cet article, nous proposons un cadre d’analyse afin de comprendre comment la gouvernance des villes-seuils s’organise relativement à leur positionnement territorial dans les chaînes de valeur mondiales. Nous soutenons que chaque configuration de gouvernance organise des relations dynamiques entre les exigences économiques mondiales, les infrastructures locales, les arrangements institutionnels et les communautés directement impliquées. Nous soulignons l’importance des régimes urbains formés de coalitions d’acteurs publics et privés situés à différents niveaux avec leurs normes et objectifs qui sont au coeur de ces configurations. Nous utilisons ce cadre pour comparer comment les questions de développement d’infrastructures à des fins de commerce international s’inscrivent dans les schèmes de gouvernance de quatre villes-seuils canadiennes

Early-stage breast cancer is not associated with the risk of marital dissolution in a large prospective study of women

Background: As breast cancer and its treatment are likely to interfere with traditional expectations of womanhood, it may affect marital stability. Methods: The risk of marital dissolution was analysed with respect to diagnosis of early-stage (T1-4N0-3M0) breast cancer in a cohort of 134 435 married Finnish women followed for a median of 17.0 married years. Age, socioeconomic status, education, number of children, duration of marriage and earlier marriages were taken into account and the effects of surgery, chemotherapy, radiotherapy and endocrine therapy were analysed separately. Results: Women with a diagnosis of early-stage breast cancer did not show increase in marital dissolution (hazard ratio -0.96, 95% confidence interval = 0.79-1.17). Neither the type of surgical procedure nor any of the oncologic treatments was associated with an increase in the risk of divorce. Conclusions: Any evidence of excess risk of marital breakdown after the diagnosis of early-stage breast cancer and its treatment was not demonstrated.Peer reviewe

Listening In on the Past: What Can Otolith δ18O Values Really Tell Us about the Environmental History of Fishes?

Oxygen isotope ratios from fish otoliths are used to discriminate marine stocks and reconstruct past climate, assuming that variations in otolith δ18O values closely reflect differences in temperature history of fish when accounting for salinity induced variability in water δ18O. To investigate this, we exploited the environmental and migratory data gathered from a decade using archival tags to study the behaviour of adult plaice (Pleuronectes platessa L.) in the North Sea. Based on the tag-derived monthly distributions of the fish and corresponding temperature and salinity estimates modelled across three consecutive years, we first predicted annual otolith δ18O values for three geographically discrete offshore sub-stocks, using three alternative plausible scenarios for otolith growth. Comparison of predicted vs. measured annual δ18O values demonstrated >96% correct prediction of sub-stock membership, irrespective of the otolith growth scenario. Pronounced inter-stock differences in δ18O values, notably in summer, provide a robust marker for reconstructing broad-scale plaice distribution in the North Sea. However, although largely congruent, measured and predicted annual δ18O values of did not fully match. Small, but consistent, offsets were also observed between individual high-resolution otolith δ18O values measured during tag recording time and corresponding δ18O predictions using concomitant tag-recorded temperatures and location-specific salinity estimates. The nature of the shifts differed among sub-stocks, suggesting specific vital effects linked to variation in physiological response to temperature. Therefore, although otolith δ18O in free-ranging fish largely reflects environmental temperature and salinity, we counsel prudence when interpreting otolith δ18O data for stock discrimination or temperature reconstruction until the mechanisms underpinning otolith δ18O signature acquisition, and associated variation, are clarified

Breast Cancer, Sickness Absence, Income and Marital Status. A Study on Life Situation 1 Year Prior Diagnosis Compared to 3 and 5 Years after Diagnosis

Background: Improved cancer survival poses important questions about future life conditions of the survivor. We examined the possible influence of a breast cancer diagnosis on subsequent working and marital status, sickness absence and income. Materials: We conducted a matched cohort study including 4,761 women 40–59 years of age and registered with primary breast cancer in a Swedish population-based clinical register during 1993–2003, and 2,3805 women without breast cancer. Information on socioeconomic standing was obtained from a social database 1 year prior and 3 and 5 years following the diagnosis. In Conditional Poisson Regression models, risk ratios (RRs) and 95 % confidence intervals (CIs) were estimated to assess the impact of a breast cancer diagnosis. Findings: Three years after diagnosis, women who had had breast cancer more often had received sickness benefits (RR = 1.49, 95 % CI 1.40–1.58) or disability pension (RR = 1.47, 95 % CI 1.37–1.58) than had women without breast cancer.

Personalized Risk Assessment for Prevention and Early Detection of Breast Cancer: Integration and Implementation (PERSPECTIVE I&I).

Early detection of breast cancer through screening reduces breast cancer mortality. The benefits of screening must also be considered within the context of potential harms (e.g., false positives, overdiagnosis). Furthermore, while breast cancer risk is highly variable within the population, most screening programs use age to determine eligibility. A risk-based approach is expected to improve the benefit-harm ratio of breast cancer screening programs. The PERSPECTIVE I&I (Personalized Risk Assessment for Prevention and Early Detection of Breast Cancer: Integration and Implementation) project seeks to improve personalized risk assessment to allow for a cost-effective, population-based approach to risk-based screening and determine best practices for implementation in Canada. This commentary describes the four inter-related activities that comprise the PERSPECTIVE I&I project. 1: Identification and validation of novel moderate to high-risk susceptibility genes. 2: Improvement, validation, and adaptation of a risk prediction web-tool for the Canadian context. 3: Development and piloting of a socio-ethical framework to support implementation of risk-based breast cancer screening. 4: Economic analysis to optimize the implementation of risk-based screening. Risk-based screening and prevention is expected to benefit all women, empowering them to work with their healthcare provider to make informed decisions about screening and prevention
