Are there two species of Pygmy Shrews (Sorex)? Revisiting the question using DNA sequence data

Pygmy Shrews in North America have variously been considered to be one species (Sorex hoyi) or two species (S. hoyi and S. thompsoni). Currently, only S. hoyi is recognized. In this study, we examine mitochondrial DNA sequence data for the cytochrome b gene to evaluate the level of differentiation and phylogeographic relationships among eleven samples of Pygmy Shrews from across Canada. Pygmy Shrews from eastern Canada (i.e., Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island) are distinct from Pygmy Shrews from western Canada (Alberta, Yukon) and Alaska. The average level of sequence divergence between these clades (3.3%) falls within the range of values for other recognized pairs of sister species of shrews. A molecular clock based on third position transversion substitutions suggests that these two lineages diverged between 0.44 and 1.67 million years ago. These molecular phylogenetic data. combined with a reinterpretation of previously published morphological data, are suggestive of separate species status for S. hoyi and S. thompsoni as has been previously argued by others. Further analysis of specimens from geographically intermediate areas (e.g., Manitoba. northern Ontario) is required to determine if there is secondary contact and/or introgression between these two putative species.

Salience of Charter Schools in Educational Policy Debates in Three Canadian Provinces: 1993-2010

School choice-the movement towards increased parental and student control over public education-has been endorsed extensively as a means of revitalizing and improving public schools. Part of this movement is the concept of charter schools, which have expanded rapidly in the United States and around the globe. In stark contrast, Canadians have remained relatively content with current educational arrangements; only 13 charter schools currently exist in Canada, all in the province of Alberta. This study sought to identify why charter schools have failed to situate themselves in Canadian education. The study used an agenda setting framework to determine the salience of charter schools as a public issue in three provinces: Alberta, British Columbia, and Ontario. Results largely indicate that over the past 18 years, charter schools have gradually declined as a salient issue. Additional discussion concerning the unique characteristics of Canadian education highlights factors that appear to discourage the expansion of such schools. However, although charter schools do not appear to be a current issue for Canadians, they may still emerge in the future, as parents and teachers continue to seek new ways of improving educational outcomes. Thus, although the impact of charter schools on public education has been minimal to date, they provide an illuminating lens towards better understanding educational reform and policy, as well as the fundamental values that shape education in Canada.

Estelle Cuffe Hawley fonds, 1852-1999, n.d.

Estelle Cuffe Hawley (1894-1995) was an educator, businesswoman and politician, who became the first woman alderman on the St. Catharines City Council. She began her career as a teacher in Peterborough in 1913, and later taught in St. Catharines at Connaught School and St. Paul’s Ward School, where she served as Principal for six years. In 1928-29, she worked as an exchange teacher in Edmonton, Alberta. This would be Estelle’s last year in the teaching profession. She moved back to St. Catharines in 1930 and began a career in business, as an employee of Sun Life Assurance Co. She remained in this profession until around 1952. It was during this period that she became very active in the community and local politics. In 1934 she was elected to the St. Catharines Board of Education, where she advocated for the improvement of teachers’ salaries, the introduction of nursing services in schools, and the inclusion of music in the curriculum. She served as a member of the school board until 1937. The following year, she became the first woman elected to the St. Catharines City Council. As an alderman, she worked to improve the community's social welfare services, serving consecutively as chairman of all committees. She established comprehensive health services (including medical, dental and nursing), in the public, separate and secondary schools of St. Catharines, the first program of its kind in Canada. She was also instrumental in establishing minimum housing standards and engaging the public in local government by arranging a series of lectures by city officials. She remained a member of City Council until 1943. The following year she campaigned unsuccessfully for the mayoralty. In 1953 she married Hubert Hawley and moved to Orillia. She continued to remain active in the community, serving as President of the Ontario Recreation Association from 1950-1953, and editor of their Bulletin from 1955-1961. During the 1960s, she worked with various groups, including the Voice of Women, the Mental Health Association and the Freedom from Hunger Campaign. In addition to this work, Estelle wrote poetry and short stories, some of which were published in the Peterborough Review, the Globe and Mail and the Canadian Churchman. Some of her short stories (often about her childhood experiences) were broadcast on the CBC, as well as her experiences as a Town Councillor (under the pseudonym Rebecca Johnson in 1961). She also broadcast a segment that was part of a series called “Winning the Peace” in April 1944. Estelle was a sought-after public speaker, speaking on topics such as peace, democracy, citizenship, education, and women’s rights. In 1976, Brock University conferred an honorary Doctor of Law degree to Estelle for her leadership as an educator, businesswoman and a stateswoman. Her husband Hubert died that same year, and Estelle subsequently moved to Mississauga. With the assistance of an Ontario Heritage Foundation grant, she began work on her memoir. She later moved back to Orillia and died there in 1995, at the age of 101.

Feeding and oviposition preferences of the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae) on six Brassicaceae host plant species

Plutella xylostella (diamondback moth, DBM) is a globally distributed Lepidopteran that feeds and oviposits almost exclusively on plants in the Brassicaceae family. DBM disperses from the southern United States and Mexico into Canada in the spring and summer. Establishment of DBM in Ontario is partially dependent upon the quantity and quality of host plants available and the preference of DBM for different hosts. Host plants include many crops such as broccoli, canola and cabbage, as well as landscape ornamentals and wild plants. It has previously been established that DBM are attracted to host plants by chemicals, specifically glucosinolates. I examined the preference of DBM among crop, wild and ornamental host plant species and how preference varies with insect life stage (3rd and 4th instar larvae and adults). Experiments included exposing DBM larvae from five populations coming from different locations in Canada to six Brassicaceae species and evaluating the preferences and weight gain over one hour. Then adult females were exposed to these same plant species and their oviposition preferences were examined. Populations from Alberta, Saskatchewan and Ontario were compared to assess differences in preference associated with geographic region or species of host plant. The ultimate goal of my study was to understand the potential of various Brassicaceae species to act as reservoirs to sustain and promote population growth of DBM, as well as sinks that may decrease DBM abundance. Results showed that garden cress (Lepidium sativum) was highly preferred over other species (wintercress, black mustard, aubretia, broccoli and ornamental kale) for both food and oviposition sources. Previous studies report that garden cress contains saponins, chemicals shown to be toxic to developing DBM larvae, however no studies have yet shown a preference for garden cress. These results provide information on a novel host plant with the potential to control DBM population growth. No difference in preferences was found among populations of DBM from various sources in Canada.

The topics of a discussion included proposed gas pipeline and "Indian land claims". He ends his report with "The experience gives new meaning to that advertising slogan 'Canada: Stand together. Understand together.'"

Letter - Cal Cavendish to Sean O'Sullivan, 25 May 1975

A letter from Cal Cavendish of Cavenidish Country in Calgary, Alberta. Cavendish has written a song about former prime minister R. Honourable John Diefenbaker. He has included the lyrics to his song. A few of the lyrics: "...Well it took a little while, but he reached his destiny, He was right, he was wrong, but he ran this big country. He didn't waste much time when he had a job to do, He worked the House of Commons like a prairie thrashing crew. Good old John, we heard you John, when a man got paid for the job when the job got done."

Johns-Manville (Canada) records, 1949-1977 (non-inclusive).

The Johns-Manville Company was founded in 1901with the merging of the H.W. Johns Manufacturing Company and the Manville Covering Company. Both companies made building materials using asbestos. The new company was based in New York, New York, and made products such as insulation and roofing materials, automotive sheet packing for cylinders, asbestos/cement, acoustical and magnesia products. Significant restructuring has occurred over the years as the company shifted from production of asbestos products to other types of building materials, such as fibre glass and forest products. Since 2001, the Johns-Manville Company has been owned by Berkshire Hathaway. The company began operations in Canada in 1918 in Asbestos, Quebec, where the Jeffrey Asbestos Mine was located. A Canadian plant opened in Port Union, Scarborough Township, in 1956, and another in North Bay, Ontario, in 1957. Both of these plants have since closed. The company currently has two plants in Canada, in Innisfail, Alberta, and Cornwall, Ontario.

Providing Genetic Testing Through the Private Sector: A View From Canada

Genetic testing technologies are rapidly moving from the research laboratory to the market place. Very little scholarship considers the implications of private genetic testing for a public health care system such as Canada’s. It is critical to consider how and if these tests should be marketed to, and purchased by, the public. It is also imperative to evaluate the extent to which genetic tests are or should be included in Canada’s public health care system, and the impact of allowing a two-tiered system for genetic testing. A series of threshold tests are presented as ways of clarifying whether a genetic test is morally appropriate, effective and safe, efficient and appropriate for public funding and whether private purchase poses special problems and requires further regulation. These thresholds also identify the research questions around which professional, public and policy debate must be sustained: What is a morally acceptable goal for genetic services? What are the appropriate benefits? What are the risks? When is it acceptable that services are not funded under health care? And how can the harms of private access be managed?

Paper Dinosaurs : field notes as finds in Robert Kroetsch's Badlands

Des dinosaures sur papier : des notes « sur le terrain » comme on en trouve dans le Badlands de Robert Kroetsch passe en revue cette œuvre postmoderne de 1975 portant sur une expédition paléontologique fictive près de la rivière Red Deer, en Alberta, conformément à la récente tendance à exiger la vérification systématique des données à la base des récits métafictifs historiographiques dans la littérature canadienne-anglaise. Inspirée de l’exploration canonique qu’a effectuée John Livingston-Lowes des plus grands poèmes de Samuel Taylor Coleridge par le biais de la mine d’or du Gutch Memorandum Book dans The Road to Xanadu, cette thèse entreprend un nouveau type de recherche qui se démarque des archives conventionnelles et de la tradition documentaire. S’appuyant sur des documents holographes non publiés provenant de dépôts d’archives situés au Québec, en Ontario et en Alberta et écrits par des collecteurs, des géologues et des paléontologues de la Commission géologique du Canada, ainsi que sur des notes « sur le terrain », des notes de recherche et des journaux personnels écrits par Robert Kroetsch pendant la rédaction de son roman Badlands, cet examen critique révèle les strates sous-jacentes inédites d’une œuvre de fiction particulière. Dans pratiquement toute fouille paléontologique, le retrait de ce qui enveloppe un spécimen révèle souvent des données supplémentaires qui peuvent, si elles sont soigneusement interprétées, offrir des indices essentiels sur les environnements paléontologiques. Ainsi, un squelette de dinosaure est rarement retiré d’une carrière stérile dans son intégralité. Il en va de même pour toute recherche sur un processus littéraire. Aucun texte ne s’autosuffit. Comme Kroetsch s’est efforcé de produire son récit sous forme d’interrogation sur la création et la transmission des données historiques, particulièrement grâce à des notes « sur le terrain », une vaste étude de ce « terrain » comprenant des intertextes de l’Antiquité, des sciences, de l’Histoire, de l’histoire populaire, de récits de voyages et de la littérature canadienne et internationale est ici menée. On y fait librement référence à des périodes et à des auteurs très diversifiés, allant de Thomas Jefferson et des tombelles à Bruce Chatwin et sa peau de « brontosaure ». Évidemment, aucune entreprise interdisciplinaire du genre ne peut être exhaustive. Ce projet se veut plutôt une vitrine littéraire réunissant des curiosités autour d’une œuvre principale, soit le Badlands de Robert Kroetsch. Réduites à leur plus simple expression, les notes « sur le terrain » constituent des messages destinés à la postérité. En explorant trois thèmes principaux, cette thèse explique comment ces messages pourraient être transmis. « Saxa Loquuntur ! », ainsi intitulé en référence à l’analogie de Freud avec l’archéologie, traite des métaphores associées aux témoignages de la pierre ; « Good Jones » porte sur les façons dont la taxinomie peut combler le désir d’un chercheur d’os de ne pas tomber dans l’oubli ; « Box 16 » suit une piste documentaire en parcourant les écrits de Kroetsch pour reconstituer tant l’élaboration d’un roman que les notions de temps, d’espace et d’origine d’une œuvre littéraire.

Relevé polarimétrique d'étoiles candidates pour des disques de débris

Le relevé DEBRIS est effectué par le télescope spatial Herschel. Il permet d’échantillonner les disques de débris autour d’étoiles de l’environnement solaire. Dans la première partie de ce mémoire, un relevé polarimétrique de 108 étoiles des candidates de DEBRIS est présenté. Utilisant le polarimètre de l’Observatoire du Mont-Mégantic, des observations ont été effectuées afin de détecter la polarisation due à la présence de disques de débris. En raison d’un faible taux de détection d’étoiles polarisées, une analyse statistique a été réalisée dans le but de comparer la polarisation d’étoiles possédant un excès dans l’infrarouge et la polarisation de celles n’en possédant pas. Utilisant la théorie de diffusion de Mie, un modèle a été construit afin de prédire la polarisation due à un disque de débris. Les résultats du modèle sont cohérents avec les observations. La deuxième partie de ce mémoire présente des tests optiques du polarimètre POL-2, construit à l’Université de Montréal. L’imageur du télescope James-Clerk-Maxwell passe de l’instrument SCUBA à l’instrument SCUBA-2, qui sera au moins cent fois plus rapide que son prédécesseur. De même, le polarimètre suit l’amélioration et un nouveau polarimètre, POL-2, a été installé sur SCUBA-2 en juillet 2010. Afin de vérifier les performances optiques de POL-2, des tests ont été exécutés dans les laboratoires sub-millimétriques de l’Université de Western Ontario en juin 2009 et de l’Université de Lethbridge en septembre 2009. Ces tests et leurs implications pour les observations futures sont discutés.

How to build a bioinformatics service in a year

Introduction: Biomedical scientists need to choose among hundreds of publicly available bioinformatics applications, tools, and databases. Librarian challenges include raising awareness to valuable resources, as well as providing support in finding and evaluating specific resources. Our objective is to implement an education program in bioinformatics similar to those offered in other North American academic libraries. Description: Our initial target clientele included four research departments of the Faculty of Medicine at Universite´ de Montréal. In January 2010, I attended two departmental meetings and interviewed a few stakeholders in order to propose a basic bioinformatics service: one-to-one consultations and a workshop on NCBI databases. The response was favourable. The workshop was thus offered once a month during the Winter and Fall semesters, and participants were invited to evaluate the workshop via an online survey. In addition, a bioinformatics subject guide was launched on the library’s website in December 2010. Outcomes: One hundred and two participants attended one of the nine NCBI workshops offered in 2010; most were graduate students (74%). The survey’s response rate was 54%. A majority of respondents thought that the bioinformatics resources featured in the workshop were relevant (95%) and that the difficulty level of exercises was appropriate (84%). Respondents also thought that their future information searches would be more efficient (93%) and that the workshop should be integrated in a course (78%). Furthermore, five bioinformatics-related reference questions were answered and two one-to-one consultations with students were performed. Discussion: The success of our bioinformatics service is growing. Future directions include extending the service to other biomedical departments, integrating the workshop in an undergraduate course, promoting the subject guide to other francophone universities, and creating a bioinformatics blog that would feature specific databases, news, and library resources.
