La stimulation thêta burst intermittente (iTBS), une technique de stimulation cérébrale non invasive (SNI) basée sur les principes du couplage thêta-gamma dans l'hippocampe, a été introduite comme méthode pour faciliter l'apprentissage, la mémoire et l'excitabilité corticale dans diverses régions du cerveau. La pratique standard consistant à utiliser un seul bloc d'iTBS pour les protocoles de stimulation cérébrale facilitatrice démontre qu'une variabilité substantielle de la réponse iTBS se produit à la fois entre les sujets et au sein d'un même sujet, contribuant ainsi à des résultats incohérents dans la littérature existante. Par conséquent, en suivant la méthodologie du double bloc de …  Lire la suite

As a corollary to The Declaration of Commitment, adopted by the United Nations General Assembly Special Session on HIV/AIDS in June 2001, the international community recently adopted a World AIDS Campaign that seeks to eradicate HIV/AIDS related stigma and discrimination. To this end, the campaign incorporates several educational strategies, such as a poster campaign, that advocate the just and equal treatment of people living with HIV/AIDS. In an effort to develop an understanding of these educational efforts, this study deconstructs the 2002-2003 World AIDS Campaign posters. While the overall results suggest that the campaign has been successful in redefining the …  Lire la suite

The beginning of our knowledge of the vitamin folic acid dates back to the discovery of Wills (1) in 1931 that the macrocytic anemia of pregnancy frequently observed in the tropics responded to oral administration of concentrated extracts of autolysed yeast. This tropical anemia resembled classical Addisonian pernicious anemia in that the bone marrow exhibited megaloblastic changes, but differed from true pernicious anemia in that achlorhydria and neurological changes were absent. A considerable advance was made in the characterization of the unknown hematopoietic factor when it was found by Wills and Stewart (2) that a similar syndrome could be induced …  Lire la suite

This thesis examines the concurrent changes in Turkish identity and in the Turkish language from the early developments in the period of the modernizing Tanzimat reforms to the Anatolian Turkish nationalism and the alphabet and language reform of the Republican era. It looks specifically at how language issues played a large role in the development of Turkish national identity towards the end of the Ottoman period, and also examines the development of Ottomanism and Islamism. Finally it looks at how the desire to promote secular Turkish nationalism in place of the old Ottoman-Islamic identity was the driving force behind the …  Lire la suite

This thesis is a study of the life and work of the nineteenth-century Ottoman Turkish journalist and activist Ali Suavi, best known for his failed attempt to overthrow Sultan Abdülhamit II in 1878. It includes a study not only of Suavi's Turkish newspaper work, but also of his oft-neglected European publications. It also includes a thorough overview of how our image of Suavi has been distorted in various ways over the years, and in particular by Turkish nationalist historiography. Far from being a Turkish nationalist or protonationalist, as many scholars have claimed, Ali Suavi was in fact an Ottoman patriot …  Lire la suite

Creativity, for Wallace Stevens, depends on connections to the natural world which can be examined through garden imagery. Chapters one and two focus on Stevens' private writing, identifying the range of garden environments and natural expanses to which he responded and associating these responses with his aesthetic sensibilities. Continental and Adamic traditions in garden imagery are explored as are contemporary practices in conservation and horticulture. Chapter three concentrates on poems which treat the garden as a locus amoenus of repose and delight where a poet can engage his imaginative faculties with sensual reality. Chapter four analyzes poems whose garden imagery …  Lire la suite

The findings of this thesis are somewhat at variance with the literature on Canadian public policy. The literature tends to accord primary importance in the federal policy-making process to forces such as political parties, bureaucratic groups, pressure groups, and the provinces. This study demonstrates that the political leadership of an individual cabinet minister and, subsequently, the political leadership of the government as a whole were of primary importance in the development of unemployment insurance policy in the 1970's. The policy interests of political leadership took precedence over those of other forces in the policy-making process. Moreover, the input of other …  Lire la suite

The recent advances in the surgical correction of some of the congenital heart defects have made the more accurate diagnosis of congenital heart disease a matter of considerable practical importance. The method of heart catheterization, which has been used extensively by a number of workers in the study of many cardiovascular problems, has recently been adapted to the investigation of congenital heart disease. The present report is based upon the study of 17 children with congenital heart disease in which this approach has been employed. [...]  Lire la suite

Le phosphore (P) est un nutriment agricole essentiel. Le prix des engrais P est très volatil et aucun producteur domestique d'engrais P n’existe au Canada. Cependant, les eaux usées municipales sont très riches en P. Pour respecter les réglementations sur les émissions de phosphore, les stations de purification municipales (WWTP) ajoutent du fer soluble pour précipiter le phosphate de fer à faible solubilité et les solides d'hydroxyphosphate de fer. Les grandes WWTPs digèrent de manière anaérobique ces solides riches en phosphore. Les produits solides finaux sont les "biosolides".À Ottawa, au Canada, les biosolides sont répandus sur le sol comme source …  Lire la suite

Cette thèse sur l'assurance aérienne débute par une présentation de l'histoire de l'aviation et un bref historique de l'assurance en la matière. Les grands principes du droit de l’assurance sont étudiés ici dans le cas précis de l'aviation aux États-Unis. Le caractère particulier du contrat ressort du rôle important de la bonne foi et de la subrogation. L'étude continue avec une analyse des principaux textes de loi qui imposent l'obligation de s'assurer, en particulier dans le transport international ou les États souverains peuvent interdire l'accès ou le survol de leur territoire quand les aéronefs ne sont pas couverts contre les …  Lire la suite

Peer motivational climate, defined as student perceptions of peer behaviours and attitudes that can promote or inhibit individual motivation, is an important feature of postsecondary learning environments. Although existing literature has provided valuable insights into the motivational functions of peers in classroom learning, the study of peer motivational climate is still in its infancy and requires greater methodological guidance, particularly in postsecondary STEM settings. Fortunately, sport psychologists have developed a measurement model of peer motivational climate in team sport settings: the widely-used Peer Motivational Climate in Youth Sport Questionnaire (PMC-YSQ). The aim of the current study was to determine the …  Lire la suite

Eskimo peoples residing along the Bering Strait region of western Alaska and Soviet Chukotka were forcibly separated by the closing of the US-USSR border in 1948. As a result, all communications between these peoples ceased for a period of 40 years. Eskimos on each side were divided into separate streams of Soviet and American jurisdiction, and with the further development of both regions following the second world War, these people became the recipients of new broadcast services. These services, conceptualized and developed from completely differing philosophies concerning the nature, function, and operation of the press, brought Eskimos into the information …  Lire la suite

This study examines long-term Inuit-European and -Euroamerican intersocietal interaction in the central Canadian Arctic. This geographical area encompasses the traditional ranges of the contiguous Copper, Netsilik and Iglulik Inuit societies. Specifically, the study analyzes and discusses changes in intra- and intergroup material trade networks and social relations resulting from indirect and direct contact with the developing capitalist world-system. Through the application of world-system theory and methodology, it is shown that indirect contact in the form of the acquisition of material trade items was a gradual, though constant, process that had a considerable impact on the cultural development of these societies. …  Lire la suite

Le cancer du sein est le cancer le plus répandu chez les femmes et plus de deux tiers des cas expriment le récepteur des estrogènes (ER). De façon significative, le cancer du sein métastatique ER-positif est la principale cause de mortalité pour le cancer du sein. Malgré le succès de l’endocrinothérapie pour traiter les cancers du sein ER-positifs, la résistance au traitement est un problème majeur et la rechute se produit souvent même si les patientes répondent initialement au traitement. Le mutant ERY537S représente l’une des mutations dans ER les plus détectées dans les biopsies métastatiques de patientes atteintes d’un …  Lire la suite

The thesis is a short novel, Prague Summer, with a critical afterward. The novel is an account of Alexandra Adams' journey to Prague the summer after the "Velvet Revolution." Juxtaposed with the narrator's first-person recollections of that time are her meditations about the body, where she explores the degree to which she can rely on her body to speak the truth. Ultimately, the text is both an account of the narrator's idiosyncratic artistic journey and a record of the processes involved in self-transformation. The required critical afterward is in two parts. The first provides a summary of Richard Rorty's account …  Lire la suite

A very wide variety of techniques has been employed in the study of the physical adsorption of vapours on solids. Since the work to be described here concerns attempts to use yet another, practically untried, technique which must be evaluated in terms of those which have been more extensively tested, it seems appropriate to discuss briefly some of the more common experimental methods, the results obtained, and some of the views generally held about the significance of the results.[...]  Lire la suite

Humans live in a world rich in multisensory information. Often information reaching one sense is completely unrelated to information reaching another sense; that is, they are spatially and temporally incongruent. The goal of the research presented in this thesis was to elucidate the behavioral and neural bases of attention to incongruent audiovisual information. Five issues were addressed: (1) developing an appropriate behavioral paradigm to test bimodal attention, (2) understanding the role of crossmodal suppression in unimodal attention, (3) exploring the interaction of auditory and visual sensory cortex during bimodal selective attention, (4) exploring the role of fronto-parietal networks in bimodal …  Lire la suite

The object of the thesis is well described by its title. It is an attempt to describe the founding, history, and organization of the Montreal Stock Exchange. The first three chapters are historical. The first traces the rise of the Stock Exchange as an institution; the second tells of the conditions under which it evolved in Canada. The third chapter describes the growth of the Exchange from its establishment in 1874 up to the present time. [...]  Lire la suite

Labrador's coastal scenery is dominated by evidence of Pleistocene glaciation. Before World War II only a few, generally bread studies touching on this subject bad been made in Labrador. From these the overwhelming effect of continental glaciation became clear. However, the chronology of glaciation had yet to be established, and little regional evidence bad been obtained to support existing hypotheses explaining the character and effects of Labrador-Quebec's glaciation. Expeditions like that of Vainö Tanner (1944) have shown that studies in detail or concentrated in small areas are essential if the deglaciation and emergence of coastal Labrador are to be understood.  Lire la suite

The works of important Anglophone African novelists, in particular those who have contributed to the growing body of literary criticism, support their claim that there is a distinctive African novel. Their novels clearly demonstrate the attachment of the novel form to the specific cultural, social and political milieu in which it is produced. The thematic concerns of Anglophone African novelists have far-reaching effects on their treatment of subject-matter and on their narrative methods. The structures of certain important novels reveal patterns of experience which are typical of African societies. Symbols and motifs which are used to further structural development in …  Lire la suite

The following thesis focuses on the medieval kabbalistic legend of R. Joseph della Reina who, using traditions of esoteric magic, conjured Satan in order to slaughter him in an unsuccessful bid to force the Redemption of Israel. A translation of a version from eighteenth century Amsterdam is presented. Influenced by the heretical ideas of Sabbatianism, this version carries two opposing significations: that of a cautionary tale on one hand, that of a tragic tale of mystical heroism on the other. Based on evidence from the fiction of Isaac Bashevis Singer, the case is made that the modern author, in line …  Lire la suite

The purpose of this thesis is two-fold: (1) to refine understanding of the relationship between anticonvulsant therapy during the first trimester of pregnancy in women with epilepsy and the risk of congenital malformation among their offspring; and (2) to assess the utility of the Saskatchewan Prescription Drug and Hospital Services databases for studies of maternal drug use and certain reproductive outcomes. In the first meta-analysis the malformation risks associated with the use of anticonvulsants in general by women with epilepsy were quantified and clarified. Comparison of the congenital malformation risk among offspring of mothers with epilepsy with first trimester anticonvulsant …  Lire la suite

Almost seventy-five percent of India's one billion people live in villages. Until recently, most of the villages were fairly isolated from external media influence. As these villages continued to modernize and gain access to services once thought to be limited to an urban environment, basic human needs began to change. Television, which used to be thought of as a luxury, has in the past 10--15 years become perceived as a necessity. Rural Maharashtrian villages have suddenly been propelled into the electronic information age. These societies that used to be defined by their own oral traditions and stories are now more …  Lire la suite

Cells are the unit structures of mammalian tissues. Each cell consists essentially of an aqueous interior containing dissolved and suspended materials enclosed within a thin plasma membrane. The plasma membrane is described in the Davson-Danielli model as a bimolecular layer of lipid sandwiched between two protein layers (Davson & Danielli, 1943). Robertson's unit membrane theory (Robertson, 1961) suggests that the bimo1ecular lipid layer is bounded on one side by a mono layer of one kind of nonlipid and on the other side by a mono1ayer of a different kind of non1ipid. This unit membrane is thought to be basic to …  Lire la suite

In an attempt to establish whether or not cardiovascular responses following noradrenaline perfusions into the lateral cerebral ventricle might be correlated with cationic (Na+, Ca++, K+, Mg++) changes in the cerebrospinal fluid, blood pressure, ECG (Lead II), and heart rate changes were recorded before, during and after perfusions with artificial CSF alone and with added noradrenaline. These studies were carried out in vagotomized, chloralosed, artificially ventilated cats. Samples of the perfusates were collected at fixed intervals to analyze the cation concentrations. Perfusions with either CSF alone or low I-noradrenaline bitartrate (NA) concentrations produced no significant changes in either blood pressure, …  Lire la suite

Le harcèlement demeure répandu dans les milieux médicaux canadiens, et a un impact négatif sur le bien-être et le développement des apprenants. Malgré la mise en place de programmes de lutte contre le harcèlement, ces derniers s'avèrent souvent inefficaces, laissant les apprenants inaptes à reconnaître et à réagir lorsque confrontés au harcèlement. Une tendance vers des solutions novatrices, telles que l’apprentissage par simulation, vise à rendre la formation médicale plus efficace et engageante. Cependant, la recherche sur de telles interventions lors de simulations anti-harcèlement en médicine reste largement inexplorée. S'appuyant sur l'efficacité d’études sur l’effet du témoin dans le domaine …  Lire la suite

In the 1790s, the English Jacobin novelists became vital participants in the fiery debates over natural and civil rights. Energized by the success of the American Revolution and inspired by the calls for l'egalite, la liberte, la surete, and la propriete in France, the Jacobin authors contributed their narratives to the British campaigns for reform of parliament and extension of the franchise. In this dissertation, I argue that the Jacobin novel furnishes crucial insights into the development of a theory of juridical rights in the late eighteenth century. Working in the early modern traditions of contract theory, writers such as …  Lire la suite

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of exocrine glands and a 43-fold greater risk for lymphoma development. This condition may occur as an isolated disorder, or in association with other rheumatic diseases. This study investigates the role of the Epstein-Barr virus (EBV) lytic protein p17, an inhibitor of apoptosis, in the pathology of SS. Using an enzyme-linked immunosorbent assay, a small subset (18-40%) of rheumatic patients, regardless of SS status, was found to have an elevated immune response to p17, compared to healthy individuals. Using immunofluorescence analysis, rheumatic patients were found to have an increased …  Lire la suite

This thesis examines the production and mobilization of Inuit knowledge in and beyond the Canadian Arctic in the context of climate change. Drawing on multi-scale, ethnographic research, it focuses in particular on the role of institutions, such as government departments and community-based organizations, in mediating between different understandings of change. Inuit knowledge is increasingly transmitted through land-based programs and supported by grant funding from outside the community. I argue that adaptation to climate change is therefore as much about understanding how to work within political and institutional frameworks as it is about responding to changes in the local environment. I …  Lire la suite

Often operating within a complicated, poorly understood environment, the process of tourism planning can be a difficult and challenging task. Technological aides have often been applied to the problems of planning, with varying levels of success. One computer simulation method used to study complex human social systems, agent-based modeling (ABM), is an approach that is increasingly used as a way to explore planning-relevant problems. Despite this promise, little work has explored the use of ABM to represent tourism dynamics, or as a support for planning, as evaluated by planners themselves. This research addresses these gaps in three steps: 1) by …  Lire la suite

Many adults assume children are colour-blind, but the research literature indicates a rise in prejudice in young children between the ages of 4 and 8 years, which then declines after. As prejudice can have detrimental effects on children's intergroup relations and academic performance, interventions that address it early on are pivotal. The present studies examine the effectiveness of two interventions to improve attitudes towards Black children in young children between the ages of 4 and 8 years, for whom previous interventions have been largely unsuccessful. Reasons for the failure of previous interventions include the lack of sophistication of the theories …  Lire la suite

Barley is one of the most ancient of cultivated plants. Even in the accounts of the earliest historians barley is mentioned. Little is known of the ancient species, however, as the whole group is so much alike that they were classed as one, namely, "barley". As an example of this de Candolle (1882) says, the mention of the occurrence of "wild and cultivated barley" by Berosus, Moses, Chorene, Pansanias, Marco Polo, and more raecently Olivier, in a given country, proves nothing because they made no reference to the species to which they referred.

Background: Sotalol and amiodarone are commonly prescribed antiarrhythmics for the treatment of post-operative atrial fibrillation (POAF), a common occurrence following coronary artery bypass graft (CABG) surgery. Though they have been shown to be effective in maintaining sinus rhythm in this population, little is known about their association with mortality.Objectives: To examine the association between sotalol and amiodarone exposure and total mortality in individuals with new-onset POAF following CABG.Methods: The linked computerised health databases of Quebec, Canada were used to identify all patients over 65 who had undergone CABG surgery and were newly diagnosed with POAF between January 1, 1993 and …  Lire la suite

This thesis examines the representation of alleged African figures on an 11th century ivory casket titled ‘Casket with Warriors and Dancers’ at the Metropolitan Museum of Art, challenging recent assertions made in the “Africa and Byzantium” exhibition. While the exhibition catalogue and wall text label the figures as African based on physical features such as hair texture and facial features, this thesis argues for a cautious approach to such categorizations and questions the reliability of identifying ethnic identities solely based on visual traits. By contextualizing the casket within its broader corpus and considering its material origins, this study proposes a …  Lire la suite
