CEO’s Letter Accompanying the Report on Corporate social Responsibility of Canadian Listed Firms: An Analysis of the Content and the Links with Some …

2016

International audience; The disclosure of Corporate Social Responsibility (CSR) by Canadian firms is not mandatory. This provides an ideal context to describe the nature of what is being freely disclosed by large firms and to study the firms’ characteristics which lead to such disclosure. We searched all TSX listed firms to find those which disclose a CSR report accompanied by a letter from the CEO. In the end, we study 89 CEO’s letters; that is, all the firms disclosing both a CSR report and a CEO’s letter. We first looked at the nature of the elements disclosed. We classified them in 3 categories: (1) actual accomplishments in the field of CSR, (2) values and (3) future objectives. The «a…

Oxygen isotope composition of North American bobcat (Lynx rufus) and puma (Puma concolor) bone phosphate: implications for provenance and climate rec…

2015

Feline carnivores are threatened by illegal wildlife trade. Tracing the provenance of unknown felid tissues via stable isotope analysis could provide important information in wildlife crime investigations. The oxygen isotope composition of mammalian skeletal phosphate (δ(18)Op) is widely applied to trace the origin of animal remains and to reconstruct migratory patterns in palaeontological, archaeological, ecological and wildlife forensic applications. Teeth and bones of terrestrial mammals form at constant body temperature in isotope equilibrium with body water, which is predominantly controlled by ingested meteoric water (δ(18)Ow) that varies systematically with latitude, altitude and cli…

Par emigrācijas (no Liepājas uz Kanādu) demogrāfisko ietekmi laika posmā no 1906. līdz 1914. gadam

2021

Darbā tiek apskatīta emigrācijas plūsma no Krievijas Impērijas uz Kanādu caur Libau (mūsdienās – Liepāju) ostu laika posmā no 1906. – 1914. gadam, kad starp Libau un Ziemeļameriku bija tieša jūras ceļu satiksme. Pētījuma pamatā ir oriģinālie kuģniecības manifesti, kas tiek salīdzināti un pretstatīti akadēmiskajiem pētījumiem par dažādām emigrantu grupām Kanādā. Pieejamie dati par galvenajām etniskajām grupām astoņu gadu posmā tiek salīdzināti, pretstatīti un papildināti ar aptaujāto emigrantu, kas emigrējuši no Krievijas Impērijas uz Kanādu šajā laika posmā, pēcteču teikto un Libau ostas apstākļu analīzi šīs emigrācijas laikā, kas balstīta šī laika krievu, britu, amerikāņu, ebreju un latvie…

Flow cytometry diagnosis in myelodysplastic syndrome: Current practice in Latin America and comparison with other regions of the world

2019

Background: Flow cytometry (FC) is a valuable tool for the diagnosis of myelodysplastic syndromes (MDS). We present results of a survey carried out to evaluate FC current practice for MDS diagnosis in Latin America (LA), focusing on markers used and characteristics of the clinical diagnostic report. Compliance to IMDSflow recommendations was also evaluated. These practices were then compared with those used in other countries. Methods: An online survey was sent through the Grupo Latino-Americano de Mielodisplasia to LA cytometrists and other international scientific societies. Results: 91 responses from 15 LA countries were received. The median of the number of markers used was 20 +/- 4.5, …

Cytotoxicity of medicinal plants of the West-Canadian Gwich׳in Native Americans towards sensitive and multidrug-resistant cancer cells

2015

Abstract Ethnopharmacological relevance Traditional medicine of the Native Americans has a long tradition of medicinal plants, which also influenced modern oncology. For instance, podophyllotoxin the active ingredient of Podophyllum peltatum L. (Berberidaceae) used by Native Americans to treat warts led to the development of etoposide and teniposide. In the present investigation, we studied 10 medicinal plants used by the Gwich׳in First Nation of West-Canada, which have been used against diverse diseases including cancer. Material and methods Sensitive and multidrug-resistant (MDR) tumor cell lines expressing various ATP-binding cassette (ABC) transporters (P-glycoprotein/ ABCB1/MDR1 , MRP1…

Démocratisation de l'enseignement supérieur et emprise des parcours

2014

This article looks at how the organization of the education system and the pathways leading to higher education enable social mobility or on the contrary the reproduction of inequalities. We thus compare three countries: France, Switzerland, and Canada. The results using panel data in these three countries show two different situations. The more higher education is valued rather than vocational training, the more inequalities tend to increase. The competition is such that it is the youth with a privileged social background who benefit more from its expansion. On the other hand, when the vocational education and training is more valued, inequalities in higher education could tend to be more …

Localization of quantitative trait loci for diapause and other photoperiodically regulated life history traits important in adaptation to seasonally …

2015

Seasonally changing environments at high latitudes present great challenges for the reproduction and survival of insects, and photoperiodic cues play an important role in helping them to synchronize their life cycle with prevalent and forthcoming conditions. We have mapped quantitative trait loci (QTL) responsible for the photoperiodic regulation of four life history traits, female reproductive diapause, cold tolerance, egg-to-eclosion development time and juvenile body weight in Drosophila montana strains from different latitudes in Canada and Finland. The F2 progeny of the cross was reared under a single photoperiod (LD cycle 16:8), which the flies from the Canadian population interpret a…

Qui suis-je : Discontinuity as part of teacher identity in Canadian French immersion

2020

The scarcity of research on French immersion teachers’ professional identity contrasts with the increasing popularity of French immersion programs in Canada and the concomitant need for French immersion teachers. This study explores the professional identity negotiation of four French immersion teachers in Alberta, Canada, with a focus on discontinuity. Semi-structured interviews conducted face-to-face with the participants were analysed using dialogic narrative analysis. The findings highlight how discontinuity is occasioned by a change in knowledge about the French immersion teaching as a profession, encountering classroom realities, shifting one’s values concerning second language learni…
