Inventing International Students: Exploring Discourses in International Student Policy Talk, 1945 â75
After the Second World War, Canadian parliamentarians showed growing interest in international students coming to Canada. The students became the subject of policy talk, which was shaped by powerful discourses emerging from the larger historical context. From 1945 to 1969, international students were seen as worthy recipients of Canadian aid, an idea that was premised on the belief that they were temporary visitors to Canada who would return to their home countries with both the skills they learned in Canadian schools and with an overall good- will towards Canada, a valuable commodity in the Cold War context. But after the Sir George Williams University affair of 1969, parliamentariansâ tone changed, and international student policy talk became suffused with discourses of fear and danger. In the years after 1969, international students were imagined as both politically and economically dangerous, an attitude that emerged as a reaction to student protest, but also re ected worries among some policymakers that Canadaâs changing immigration system, and its move away from primarily Europeans sources for immigrants, was a threat to the stability of Canadian culture.RĂ©sumĂ©AprĂšs la Seconde Guerre mondiale, les parlementaires canadiens ont montrĂ© un intĂ©rĂȘt crois- sant pour la venue au pays dâĂ©tudiants internationaux. Ces derniers devinrent un sujet de discussions politiques qui donna lieu Ă des discours Ă©mouvants alimentĂ©s par un vaste contexte historique. De 1945 Ă 1969, les Ă©tudiants internationaux Ă©taient vus comme des rĂ©cipiendaires dignes de lâaide canadienne. Cette idĂ©e sâappuyait sur lâimpression quâils Ă©taient des rĂ©sidents temporaires au Canada et quâils retourneraient dans leur pays non seulement avec les com- pĂ©tences acquises dans les Ă©tablissements dâenseignement, mais quâils af cheraient aussi leur bienveillance envers le Canada, une valeur inestimable dans un contexte de Guerre froide. Cependant, aprĂšs lâaffaire de lâUniversitĂ© Sir George Williams, en 1969, le ton des parlemen- taires canadiens a changĂ©. Les discussions politiques sur les Ă©tudiants internationaux furent teintĂ©es par des idĂ©es de peur et dâapprĂ©hension. AprĂšs 1969, on imagina les Ă©tudiants inter- nationaux comme dangereux sur les plans politique et Ă©conomique. Cette attitude fut une rĂ©action aux protestations Ă©tudiantes, mais re Ă©tait Ă©galement les prĂ©occupations de certains politiciens face aux changements du systĂšme dâimmigration qui ne privilĂ©giait plus les Ă©tu- diants venus dâEurope, ce qui prĂ©sentait une menace Ă la culture canadienne.
Genome-wide association studies identify 137 genetic loci for DNA methylation biomarkers of aging
Background Biological aging estimators derived from DNA methylation data are heritable and correlate with morbidity and mortality. Consequently, identification of genetic and environmental contributors to the variation in these measures in populations has become a major goal in the field. Results Leveraging DNA methylation and SNP data from more than 40,000 individuals, we identify 137 genome-wide significant loci, of which 113 are novel, from genome-wide association study (GWAS) meta-analyses of four epigenetic clocks and epigenetic surrogate markers for granulocyte proportions and plasminogen activator inhibitor 1 levels, respectively. We find evidence for shared genetic loci associated with the Horvath clock and expression of transcripts encoding genes linked to lipid metabolism and immune function. Notably, these loci are independent of those reported to regulate DNA methylation levels at constituent clock CpGs. A polygenic score for GrimAge acceleration showed strong associations with adiposity-related traits, educational attainment, parental longevity, and C-reactive protein levels. Conclusion This study illuminates the genetic architecture underlying epigenetic aging and its shared genetic contributions with lifestyle factors and longevity.Peer reviewe
Polycystic ovary syndrome
The document attached has been archived with permission from the editor of the Medical Journal of Australia. An external link to the publisherâs copy is included.Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle changes, medication and potentially surgery for the prevention and management of excess weight, androgen suppression and/or blockade, endometrial protection, reproductive therapy and the detection and treatment of psychological features. This Primer summarizes the current state of knowledge regarding the epidemiology, mechanisms and pathophysiology, diagnosis, screening and prevention, management and future investigational directions of the disorder.Robert J Norman, Ruijin Wu and Marcin T Stankiewic
State of the Art Review: Emerging Therapies: The Use of Insulin Sensitizers in the Treatment of Adolescents with Polycystic Ovary Syndrome (PCOS)
PCOS, a heterogeneous disorder characterized by cystic ovarian morphology, androgen excess, and/or irregular periods, emerges during or shortly after puberty. Peri- and post-pubertal obesity, insulin resistance and consequent hyperinsulinemia are highly prevalent co-morbidities of PCOS and promote an ongoing state of excess androgen. Given the relationship of insulin to androgen excess, reduction of insulin secretion and/or improvement of its action at target tissues offer the possibility of improving the physical stigmata of androgen excess by correction of the reproductive dysfunction and preventing metabolic derangements from becoming entrenched. While lifestyle changes that concentrate on behavioral, dietary and exercise regimens should be considered as first line therapy for weight reduction and normalization of insulin levels in adolescents with PCOS, several therapeutic options are available and in wide use, including oral contraceptives, metformin, thiazolidenediones and spironolactone. Overwhelmingly, the data on the safety and efficacy of these medications derive from the adult PCOS literature. Despite the paucity of randomized control trials to adequately evaluate these modalities in adolescents, their use, particularly that of metformin, has gained popularity in the pediatric endocrine community. In this article, we present an overview of the use of insulin sensitizing medications in PCOS and review both the adult and (where available) adolescent literature, focusing specifically on the use of metformin in both mono- and combination therapy

Border Imperialism and Exclusion in Canadian Parliamentary Talk about International Students
Although there is a rich critical literature examining international student policy in Canada, very little of it considers the views of Members of Parliament. MPs have limited direct influence over international student policy, but their policy talk about international students defines the context within which such policy is developed. For that reason Parliamentary debate deserves study. This paper examines MPsâ discussion of international students between 1984 and 2019, tracing themes in MP policy talk over the globalization era. It finds that MPs evince remarkably consistent attitudes towards international students. Throughout the period MP policy talk shows that Parliamentarians saw international students as outsiders who were only ofvalue to the extent that they could be made to serve Canadaâs economic or political agenda. The uniformity of this attitude and the lack of dissenting voices suggest that MPsâ views may be a significant barrier to reforming international student policy in Canada.Bien quâil existe une riche littĂ©rature critique sur la politique relative aux Ă©tudiants Ă©trangers au Canada, trĂšs peu dâĂ©tudes se penchent sur les opinions des dĂ©putĂ©s Ă ce sujet. Lâinfluence directe de ces derniers en cette matiĂšre est limitĂ©e, mais leurs discussions dĂ©finissent le contexte dans lequel cette politique est Ă©laborĂ©e. Pour cette raison, les dĂ©bats parlementaires mĂ©ritent dâĂȘtre Ă©tudiĂ©s. Le prĂ©sent article examine les discussions des dĂ©putĂ©s au sujet des Ă©tudiants Ă©trangers entre 1984 et 2019. Ce faisant, il retrace les thĂšmes qui les ont traversĂ©es Ă travers lâĂ©poque de la mondialisation. Il en ressort que les dĂ©putĂ©s font montre dâune attitude remarquablement cohĂ©rente en ce qui a trait aux Ă©tudiants Ă©trangers. Sur toute la pĂ©riode,ces discussions dĂ©montrent que les parlementaires ne considĂšrent la valeur des Ă©tudiants Ă©trangers que dans la mesure oĂč ils peuvent servir le programme Ă©conomique ou politique du Canada. La constance de cette attitude et lâabsence de voix dissidentes suggĂšrent que les opinions des dĂ©putĂ©s pourraient constituer un obstacle important Ă une rĂ©forme des politiques relatives aux Ă©tudiants Ă©trangers au Canad
From âfriendly relationsâ to differential fees : a history of international student policy in Canada since World War II
This dissertation examines the development of policy related to international undergraduate students in Canada since the end of the Second World War. It draws on archival materials from the federal, British Columbia, and Ontario governments, and seven institutions: the University of Toronto, Carleton University, Wilfrid Laurier University, Seneca College, the University of British Columbia, Simon Fraser University, and Kwantlen Polytechnic University.
The dissertation unearths the initial proto-policies developed by non-governmental agencies that provided services for international students, and examines how the priorities of these service groups were inherited by institutions as the organizations were formally incorporated into universities and colleges. It follows these early policy makers as they responded to international studentsâ own emerging consciousness, and the transition of students from welcome visitors to dangerous possible immigrants in the eyes of Members of Parliament. Out of this new context emerged differential tuition fees, which were first contested, then embraced by institutions. As differential fees became normalized, they reshaped institutions, driving them to dramatically expand recruitment efforts of international students. The dissertation concludes by examining another unintended emerging policy, as Canadian immigration policy and international student recruitment efforts combine to situate post-secondary institutions as immigrant selectors.
In the process, the dissertation demonstrates the development of international student policy in Canada was uneven and reactive. Policy was crafted informally at the institutional level, or by non-governmental actors, and then formalized by institutions or governments when convenient. Although policies emerged fitfully, Canadian policy makers adopted policies only when beneficial for Canada and Canadian institutions, either politically or economically. Yet international student policies were consistently framed as an expression of the âinternationalismâ of Canadian higher education. However, the different attitudes towards international students embedded in policy demonstrate competing conceptions of internationalism at the institutional and government level. Finally, the dissertation argues that contemporary policy regarding international students, including the 2014 development of a Federal international education strategy, are not a break from this history but instead the culmination of decades of policy debates.Education, Faculty ofEducational Studies (EDST), Department ofGraduat
Pathway Colleges: A New Institutional Form in Canada
Canadaâs public universities seeking to increase their international student recruitment are building pathways that allow students who lack the academic or language credentials needed for direct entry to the university to upgrade their skills and eventually matriculate to the larger institution. These pathway collegesare a new institutional form in Canada, but as yet they have received almost no attention from scholars. This paper offers a brief typology of these emerging institutions and offers some suggestions for future research
