Air conditioning and heat-related mortality: a multi-country longitudinal study

2020

Background: Air conditioning has been proposed as one of the key factors explaining reductions of heat-related mortality risks observed in the last decades. However, direct evidence is still limited. Methods: We used a multi-country, multi-city, longitudinal design to quantify the independent role of air conditioning in reported attenuation in risk. We collected daily time series of mortality, mean temperature, and yearly air conditioning prevalence for 311 locations in Canada, Japan, Spain, and the USA between 1972 and 2009. For each city and sub-period, we fitted a quasi-Poisson regression combined with distributed lag non-linear models to estimate summer-only temperature–mortality associ…

Comprehensive database on Induan (Lower Triassic) to Sinemurian (Lower Jurassic) marine bivalve genera and their paleobiogeographic record

2014

Marine bivalve genera that were described or mentioned for Triassic and Lower Jurassic deposits worldwide are reviewed in terms of their validity, stratigraphic range, paleogeographic distribution, paleoautoecology and shell mineralogy. Data were originally compiled at species level and are arranged systematically. A brief discussion for each genus includes synonymy, taxonomic status and included subgenera, as well as current uncertainties about their validity and range. The distribution of each genus is also shown on paleogeographic maps. Type species and first and last appearances of each genus are also mentioned. We recognize as valid 280 genera and their included subgenera, and we furth…

Unequal Attainments: Ethnic educational inequalities in ten Western countries

2014

Western countries have become increasingly diverse in recent decades and these demographic trends are certain to continue. The resulting ethnic diversity is a major challenge to policy-makers, who need to tackle issues of social justice and social integration. Education plays a pivotal role since it is the major stepping stone for the children of immigrants to successful economic integration and also plays a major role in social and political integration more generally since education gives access to the skills, resources and contacts which enable individuals to participate fully in the life of their society. Our central research questions are: Do the descendants of migrants experience equa…

Pathways enabling educational success for vulnerable immigrants in Switzerland, Canada and France

2014

Parcours d'études favorisant l'accès à l'enseignement supérieur des jeunes d'origine immigrée en Suisse, France et au Canada - Les politiques éducatives des dernières décennies ont favorisé les poursuites d'études des élèves jusqu'aux niveaux post-secondaires. Ces politiques devraient contribuer à réduire certaines inégalités connues dans le système éducatif en améliorant la réussite scolaire des groupes défavorisés ou vulnérables tels les enfants d'origine immigrée ou de milieu social modeste. Dans cet article, nous cherchons à préciser non seulement si, mais aussi comment les parcours scolaires, permettent l'accès à l'enseignement supérieur des jeunes d'origine immigrée, en mobilisant tro…

Parcours scolaires, accès aux études supérieures et mobilité sociale : comparaison entre la France, la Suisse et le Canada

2016

Le présent article examine dans quelle mesure l’organisation des trajectoires scolaires et les parcours conduisant à l'enseignement supérieur favorisent la mobilité sociale ou au contraire la reproduction des inégalités. Nous avons comparé trois pays : la France, la Suisse et le Canada. Les résultats obtenus à partir des données tirées des panels d’enquêtes menées dans ces trois pays permettent d’observer deux situations inversées. Plus l’enseignement supérieur est valorisé au détriment de la formation professionnelle, plus les inégalités ont tendance à s’exacerber. La compétition y est telle que ce sont les jeunes de milieu favorisé qui tirent davantage profit de son expansion. Par contre,…

L'accessibilité aux études postsecondaires au Canada : l'influence des facteurs sociaux et scolaires

2013

Au Canada, l'éducation postsecondaire est de compétence provinciale. Chacune des dix provinces possède son propre système, avec ses propres particularités en termes de structure et d'organisation. Afin de favoriser l'accessibilité, les différentes provinces ont mis en avant, à partir des années 1960, des politiques visant à augmenter l'accessibilité, par exemple à travers l'offre (création de nouveaux établissements ou développement de structures existantes) ou par la réduction des barrières financières (p. ex. gel des frais de scolarité, systèmes de prêts et bourses) (Diallo et al., 2009). Pendant cette période, certains groupes jusque-là sous-représentés dans les études postsecondaires, t…

Job Insecurity in Nursing: A Bibliometric Analysis

2021

Nurses are a key workforce in the international health system, and as such maintaining optimal working conditions is critical for preserving their well-being and good performance. One of the psychosocial risks that can have a major impact on them is job insecurity. This study aimed to carry out a bibliometric analysis, mapping job insecurity in 128 articles in nursing, and to determine the most important findings in the literature. The search was conducted in the Web of Science Core Collection database using the Science Citation Index (SCI)-Expanded and Social Sciences Citation Index (SSCI) indexes on 6 March 2020. This field of discipline has recently been established and has experienced s…

The histology of ovarian cancer: worldwide distribution and implications for international survival comparisons (CONCORD-2).

2016

OBJECTIVE: Ovarian cancers comprise several histologically distinct tumour groups with widely different prognosis. We aimed to describe the worldwide distribution of ovarian cancer histology and to understand what role this may play in international variation in survival. METHODS: The CONCORD programme is the largest population-based study of global trends in cancer survival. Data on 681,759 women diagnosed during 1995-2009 with cancer of the ovary, fallopian tube, peritoneum and retroperitonum in 51 countries were included. We categorised ovarian tumours into six histological groups, and explored the worldwide distribution of histology. RESULTS: During 2005-2009, type II epithelial tumours…
