Conjuring Canadas: Historians and the Quest to Define a Canadian Nation and its Past, 1920-1967

This dissertation examines the various ways in which Canadian historical researchers confronted the “Canada question,” namely the challenge of defining the basis of a unified national community. In doing so, it follows the scholarship and activities of a network of historians and intellectuals centred on the Canadian Historical Review, a quarterly publication founded in 1920. This study examines their scholarship with the aim of identifying not only the various solutions they posed to the problem, but also the philosophical undercurrents that informed their reasoning in the process. It also traces the rise of a rival network in the Revue d’histoire de l’Amérique française, a French-language historical publication founded in 1947 that by its very existence posed a significant challenge to the definition of the nation at the core of the Canadian Historical Review. This dissertation argues that the network bound together by the Review was engaged in a hegemonic project, one that sought to present a particular definition of Canada through a historical narrative that rested upon a liberal logic. Yet the greatest sustained challenge they faced in this endeavour emerged from Francophone historical scholars, who, although proposing vastly different Canadas to those imagined at the Canadian Historical Review, came under the sway of a number of liberal currents of thought as well. A detailed summary of the key traits of these liberal Canadas is found in the conclusion.

Gross and net nitrogen transformation rates and availability in late summer in tall shrub and birch hummock ecosystems of the Canadian low Arctic

Climate change is occurring most rapidly in the Arctic where warming has been twice as fast as the rest of the globe over the last few decades. Arctic soils contain a vast store of carbon and warmer arctic soils may mediate current atmospheric CO2 concentrations and global warming trends. Warmer soils could increase nutrient availability to plants, leading to increased primary production and sequestration of CO2. Presumably because of these effects of warming on shrub ecosystems, shrubs have been expanding across the arctic over the last 50 years, Arctic shrub expansion may track or cause changes in nutrient cycling and availability that favour growth of larger, denser shrubs. This study aimed at measuring gross and net nitrogen cycling rates, major soil nitrogen and carbon pool sizes, and elucidating controls on nutrient cycling and availability between a mesic birch (Betula nana) hummock tundra ecosystem and an ecosystem of dense, tall, birch (B. nana) shrubs. Nitrogen cycling and availability was enhanced at the tall shrub ecosystem compared to the birch hummock ecosystem. Net nitrogen immobilization by microbes was approximately threefold greater at the tall shrub ecosystem. This was in part because of larger microbial biomass nitrogen and carbon (interpreted as a larger microbial community) at the tall shrub ecosystem. Nitrogen inputs via litter were significantly larger at the tall shrub ecosystem and were hypothesized to be the major contributor to the higher dissolved organic and inorganic nitrogen pools in the soil at the tall shrub ecosystem. The results from this study suggest a positive feedback mechanism between litter nitrogen inputs and the enhancement of nitrogen cycling and availability as a driver of shrub expansion across the Arctic.

Single Canadian mothers of Jamaican heritage share experiences about their children's education

This thesis examines the experiences of four single Canadian mothers of Jamaican heritage with respect to their children’s education. Four themes suggested in the literature—beliefs, practices, barriers, and supports—guided the research. The interviews with the mothers largely confirmed previous research in the field. As such, all the mothers believed that it was a shared responsibility between parents and teachers in supporting children’s education. The mothers’ practices included primarily at-home support and to a lesser extent at-school support but did not include strict discipline. The barriers most salient for these mothers were lack of time and resources. To help overcome these barriers, the mothers relied on domestic kin networks. From these findings, the thesis provides implications for both research and practice.

Calling for resistance: The political economy of Indian and Canadian call centre industries

Call centres have in the last three decades come to define the interaction between corporations, governments, and other institutions and their respective customers, citizens, and members. From telemarketing to tele-health services, to credit card assistance, and even emergency response systems, call centres function as a nexus mediating technologically enabled labour practices with the commodification of services. Because of the ubiquitous nature of the call centre in post-industrial capitalism, the banality of these interactions often overshadows the nature of work and labour in this now-global sector. Advances in telecommunication technologies and the globalization of management practices designed to oversee and maintain standardized labour processes have made call centre work an international phenomenon. Simultaneously, these developments have dislocated assumptions about the geographic and spatial seat of work in what is defined here as the new international division of knowledge labour. The offshoring and outsourcing of call centre employment, part of the larger information technology and information technology enabled services sectors, has become a growing practice amongst governments and corporations in their attempts at controlling costs. Leading offshore destinations for call centre work, such as Canada and India, emerged as prominent locations for call centre work for these reasons. While incredible advances in technology have permitted the use of distant and “offshore” labour forces, the grander reshaping of an international political economy of communications has allowed for the acceleration of these processes. New and established labour unions have responded to these changes in the global regimes of work by seeking to organize call centre workers. These efforts have been assisted by a range of forces, not least of which is the condition of work itself, but also attempts by global union federations to build a bridge between international unionism and local organizing campaigns in the Global South and Global North. Through an examination of trade union interventions in the call centre industries located in Canada and India, this dissertation contributes to research on post-industrial employment by using political economy as a juncture between development studies, critical communications, and labour studies.
