River regulation imposes direct changes on flow and sediment delivery, producing a suite of downstream responses in channel morphology. On the Peace River in northern British Columbia and Alberta, the W.A.C. Bennett hydroelectric dam has reduced peak flows while leaving sediment load effectively unchanged. My research aims to identify systematic, regulation-induced patterns of channel gradation in the mainstem Peace and its tributaries below the dam. The significance of regulation within the natural variability of basin hydrology is assessed by comparing actual regulated river flows to simulated flows based on reservoir level fluctuations. Mainstem bed elevation changes are assessed from repeatedly surveyed cross-sections and specific gauge records, supplemented by analysis of channel planform change. Results show degradation to be minimal, due to the naturally armoured gravel bed and elimination of competent flows. The predominant pattern in the upper regulated reaches is one of aggradation below tributary confluences and other sediment sources. In the long term, the Peace River may be raising its proximal bed to compensate for a loss of sediment transport capacity since regulation. Backchannel abandonment and other planform changes appear to be occurring more slowly, and may be less important to river slope adjustment. Data from the lower river are few and inconclusive. Tributary gradation was investigated by means of air photo, field surveys and dendrochronology of young floodplains. These methods reveal a range of responses to regulation, including degradation, aggradation and no apparent change. Degradation due to reduced tributary base level appears to attenuate downstream as the Peace River flood is restored by unregulated tributary flows, though this trend is complicated by other factors such as tributary sediment supply, flood timing between tributary and mainstem, and ice activity. Aggradation due to tributary fan growth may mitigate degradation; it is a less prominent response, though it appears to predominate in the lower Smoky River. Regulation is a secondary effect in the tributaries, and its influence on gradation has been limited. On the mainstem, however, it is a primary change, and the resulting channel gradation will take a long time to complete.

Implementing sustainability initiatives within a post-secondary institution can start with educating and influencing staff and students. It requires thoughtful planning and preparation in order to realistically expect the target audience to accept, implement, and adopt such plans. Assuming education and encouragement towards sustainable behaviour are the foundation of successful implementation, including the stakeholders in the planning process would seem to be a logical approach in educating for sustainable behaviour. Since post-secondary institutions are communities within communities, they provide a logical starting point to research the challenges of implementing a sustainability education initiative. This thesis explores potential implementation barriers of a recently proposed initiative within the 2010- 2014 Olds College Business Plan of educating staff and students of Olds College about sustainability, so that they become engaged participants in the creation of a College-wide sustainability plan.

This study investigated the influence of geomorphic context and flow regulation on cottonwood (Populus) age structure, stand size, recruitment rates, and annual radial growth patterns along the Oldman River in southern Alberta. Dendrochronological techniques were used to age trees, establish population structures, and measure annual radial growth on three reaches in differing geomorphic contexts. Cottonwoods within a narrow, 'constrained' reach were more negatively impacted by partial dewatering of the river, but responded more favorably to increased late-summer flows combined with suitable recruitment conditions than the trees within a wide, 'alluvial' reach. A positive linear relationship between early-summer peak discharge and annual radial growth was found only on the alluvial reach. However, these trees also had the slowest growth rates, likely due to competition between trees because alluvial reaches often support large, dense stands of cottonwoods. This study demonstrates the need to consider the geomorphic context when studying cottonwood responses to river regulation. / xvi, 141 leaves : ill. ; 29 cm.

On 14 February 1933, the citizens of Blairmore, Alberta, elected a Communist town council; this so-called Red administration remained in power until 1936. Best known for their seemingly outrageous actions, the council exists within current historiography as either the result of protracted depression or an example of the success experienced by the Communist Party of Canada during this period. This thesis will challenge both arguments, demonstrating that a series of social, economic, and political experiences resulted in the election of known Communists being socially permissible by 1933. It will be demonstrated that the agenda of council was not strictly “Communist,” rather it represented a balance between radical and populist programs, thus enabling council to challenge capitalist society while providing a practical response to the local effects of the Depression. The deterioration of this balance by 1936, coupled with a series of scandals, was resultant in the council’s electoral downfall. / vii, 161 leaves ; 29 cm.

Morphology related to the South Saskatchewan River in the Outlook Saskatoon region is basically a product of the complex relationships between fluvial activity, glacial and lacustrine history and surficial materials. / During deglaciation, the river experienced numerous major changes before becoming incised in its present location. Channel scars and deltaic-alluvial deposits are widespread. / The present valley proper shows marked local variation in overall width; terrace characteristics; occurrence of slumping, and features of the valley floor including floor and river widths, gradients, braiding, meandering, channel bars and islands, and flood plain characteristics and development. Differences are largely the result of (a) pronounced variations in the resistance to erosion of materials of the valley sides and floor; (b) the influence of an alluvium-filled gut, underlying the river in the south, on width and slumping; and (c) the influence, in the north, of sharp bends which were inherited from a braided network of early high-level channels.

Across Canada, municipalities have been struggling to alleviate the poverty of increasing numbers of homeless people and panhandlers on city streets. Simultaneously, tensions have risen between these street people and the general public. This thesis is a narrative study of the current conflict between panhandlers and other community stakeholders in Calgary, Alberta. This study presents the diverse viewpoints and voices of people who panhandle, homeless people, the general public, the downtown business community, social service providers, city bureaucrats and police officers. This study examines how identity politics and broader social ideologies shape face-to-face street encounters and influence debates over public policy at an institutional level. The relationship between panhandlers and the public is typically one marked by social distance. The current approach to panhandlers involves treating them as "strangers within our midst." This approach undermines their citizenship and heightens tensions within the community more so than would an approach that emphasizes their commonality with the larger society and their rights within civic space.

Los trabajos que requieren capacidad de cómputo intensiva necesitan de un administrador de carga de trabajo especializado, que brinde mecanismos de cola, políticas de planificación, esquema de prioridades, monitoreo y administración de recursos. Cuando los usuarios emiten sus trabajos, el administrador deberá decidir cuándo y dónde ejecutarlos, teniendo en cuenta sus requerimientos, realizar un monitoreo del progreso e informar al usuario cuando haya finalizado su ejecución. Al integrar capacidad de proceso, almacenamiento y acceso a recursos remotos, se podrán ejecutar aplicaciones que no pueden procesarse en una computadora única y así satisfacer demandas de cómputo complejas. En este trabajo se discute el uso de Condor como gestor de recursos disponibles en un entorno de Computación de Alta Disponibilidad ya que es un sistema que ofrece funcionalidades de HTC donde los usuarios no tienen que preocuparse, por ejemplo, dónde enviar sus trabajos para ejecución, ni de tener que enviar manualmente un gran número de ellos cuando así lo requieran.
