Kabuli chickpea (<i>Cicer arietinum</i> L.) has two leaf types, the fern and unifoliate. Yield potential is limited for kabuli chickpea in Saskatchewan. It is limited by a short-season, a semi-arid environment, and end-of-season rainfall. Manipulating plant population, and choosing chickpea cultivars with the best leaf type for biomass production, radiation interception and yield for the early, middle, or late growth season, may increase chickpea yield. Therefore, the objectives of this study were: to (i) determine the relationship between leaf type and key growth parameters of six chickpea cultivars varying in leaf morphology at moderate and high plant population densities; (іі) to characterize the reaction of the fern and unifoliate leaf to altered canopy light environments. Different light environments were created by 50% defoliation at vegetative growth, first flower, and 50% shading from vegetative growth to first flower, as well as two light enrichment treatments initiated at the first flower and pod formation stages.<p> Fern leaf cultivars exhibited higher maximum light interception, seasonal cumulative intercepted radiation and a higher harvest index compared to unifoliate leaf cultivars. However, both leaf type canopies had less than 95% light interception for most of the season. The fern and unifoliate leaf type contributed to similar radiation use efficiency in three out of four location-years. In addition, fern leaf cultivars produced significantly higher seed yield than cultivars with unifoliate leaves.<p>Plant density influenced growth parameters. For example, the 45 plants m-2 treatment had a higher harvest index than the 85 plants m-2 treatment, in two location-years, while both population treatments were similar in the other two location-years. Yield of chickpea was increased by higher plant population in only one location-year, but was not significantly affected by plant population in the other location-years. The effect of canopy light environment manipulation on chickpea yield depended on the stages of plant development when they were applied. Defoliation at vegetative growth and first flower had no effect on yield. However, plants responded significantly to the 50% shade treatment; the crop growth rate, harvest index and yield were less in the shaded treatment compared to the control. Shading also increased plant height. Light enrichment treatments increased the yield. However, the degree of yield increase was greater when light enrichment occurred at first flower, than at the later stage of pod formation. These results highlighted the importance of the amount of irradiance during the flowering stage. It was concluded that chickpea breeders should select lines with fern leaves for improved radiation interception when breeding cultivars for semiarid short-season environments such as in Saskatchewan. Management and breeding practices should ensure that the crop can make efficient use of the solar radiation at flowering to maximize yield. Improvement at the canopy and subsequent yield level is yet to be made in Saskatchewan environments by increased light interception, increased growth before flowering, and increased and stable harvest index.

In the dominant North American imagination, the asylum has always been a place of the other in society. Stories of Saskatchewan asylums and their reincarnations as mental hospitals are filled with early twentieth century horror narratives and redemptive tales of mid-century scientific progress: the monstrousness of the labyrinthine asylum structures and its arcane treatments, the modern marvels of the experimental therapies and the lives saved by the scientific authorities. Still some of the most infamous buildings to haunt provincial imagination, mental hospitals became more than buildings designed to treat disease in Saskatchewan: they were a cultural phenomenon. The hospitals themselves became social objects invested with meanings which shaped social relations.<p> This thesis investigates how the built structure of the asylum and in particular the North Battleford and Weyburn Mental Hospitals were perceived, experienced and theorized in early twentieth century and post-war Saskatchewan society. In analyzing architectural drawings, floor plans, television documentaries, photographs and patients' personal stories, this dissertation takes a critical look at how patients and staff were situated within the built structure at certain points and in particular during the Weyburn Mental Hospitals extensive earlier twentieth century history and its mid-century re-birth as a modern psychiatric research centre. Feminist and post-colonial debates about the history of medicine and eugenics, spatial and socio-practices of power within built structure and the representation of patients and health professionals in colonial and modern society are also examined as a means to situate the discussion of the mental hospital within the broader context of the discussion on spatial discourses.

The late Arthur Silver Morton has contributed immensely to our understanding and preservation of western Canadian history. One of Mortons joys was locating remains of long forgotten fur trade posts. As a result, a large number of the Saskatchewan fur trade posts that we know of were located and recorded by Morton. The majority of Mortons investigations took place throughout the 1930s and 1940s. Morton consulted whatever historic sources were available to him at the time: numerous historic documents, ethnographic accounts and local histories.<p> There has been archaeological evidence that suggests Morton misidentified numerous fur trade post sites. For example, research at the Hudsons Bay Companys South Branch House (1786-1794), which Morton identified in 1944, has sparked some controversy as to whether or not it is that particular post. As a result, this provides the author with an excellent chance to examine how Morton identified Saskatchewan fur trade posts and to determine through archaeological excavations and historical documents the accuracy of Mortons historical site designation at South Branch House.<p> A critical approach to Mortons work will determine how accurate his work is for contemporary archaeological investigations of fur trade posts. Furthermore, this thesis may provide historical archaeologists with insights as to how to go about identifying fur trade posts, which will contribute to our overall understanding of the western Canadian fur trade.

The ruins of the La Colle Falls Hydro Dam encompass two very distinct topographies: the physical landscape of the vast Canadian Northwest, and the complex emotional terrain of the urban mythology of the city of Prince Albert, Saskatchewan. In 1912 the city embarked on the ambitious project, building a dam and shipping lock on the North Saskatchewan River to supply the city with cheap and plentiful hydroelectric power and create a navigable inland shipping route from Winnipeg to Edmonton. The people of the community believed that it was poised to become a new commercial centre of the west, a key manufacturing and industrial metropolis. Instead, the project became an enormous and ruinous financial debacle that embarrassed the residents and crippled the urban growth of the city for nearly a century. Its failure, and the consequent suffering it brought permeate local legend to this day. The solution to this negative residual memory exists in the hydro dam’s own genesis: the spiritual and functional significance of the North Saskatchewan River as a site of traditional Aboriginal healing and a crucial regional amenity. Unable to bridle the waters of the North Saskatchewan, the dam instead comprises a dramatic visual testimony to the effects of an enormous work of construction on the panoramic Saskatchewan landscape, and an ideal setting to address the interface of man, structure, and the human body in the natural world. This thesis uses the ruins of the dam as a physical armature on which to construct a spa complex, an architectural insertion that will complete the dam, and present a positive alternative ending to its story. The spa is viewed as a place of intimate physical contact and remedial personal reflection that acknowledges the dramatic landscapes surrounding it, engages the senses, and simultaneously heals the bodies of the patrons while reconciling the latent negative historical memory of the original hydro dam project.

The latest evidence indicates that 50,000 Canadians will experience a stroke in 2013. The hospital care, rehabilitation, and long term care associated with a stroke places a significant burden on our health care system. Lost productivity and premature death have an immeasurable impact on communities in our province as well as the rest of the country. Small, less populated regions such as Saskatchewan may be underrepresented in national data utilized in the development of national prevention and treatment strategies across the country. The absence of local research has necessitated the use of national information to guide prevention, treatment education and programming in Saskatchewan. The goals of this study was to provide a descriptive profile of stroke and transient ischemic attack cases admitted to Royal University Hospital over the period of April 1, 2009 to March 31st, 2010 and to assess the acute management of these cases as defined in the Canadian Best Practice Recommendations for Stroke Care (Strategy, 2010). A randomized sample of 200 cases 55 years and older was selected for a retrospective descriptive study involving review of adult stroke case records. Personal demographics and healthcare performance through the use of measures provided in The Canadian Best Practice Recommendations for Stroke Care (Canadian Stroke Network (CSN) and Heart and Stroke Foundation of Canada (HSFC), 2010) were evaluated. The results indicated many similarities to available national information on type of stroke, risk factors, gender, and age. Hospital adherence to national guidelines comparing selected indicators was exceeded in some areas, and met in most. The remaining indicators provide an opportunity for improvement and possibly more research. This regional information supplements the available Canadian information and could be used to guide planning and care strategically targeting Saskatchewan residents and increasing their potential for success.

Gardiner Dam is located on the South Saskatchewan River approximately 100 km south of Saskatoon, SK. After the start of construction, the River Embankment experienced downstream movement in the shale portion of the foundation. Observed movements are occurring on a well-defined shear plane within the shale layer. This continuing foundation deformation raises concerns regarding the long-term stability of the structure and the effect of continuing deformation on the integrity of the embankment and ancillary works. The mechanism(s) responsible for the ongoing movements are not fully understood. As such, prediction of on-going deformation has had only a limited success. In the work presented in this dissertation, historic geotechnical instrumentation data was used to identify a potential mechanism of movement within the shale foundation. The potential mechanism thus identified can be briefly described as a combination of elastic deformation and consolidation within the shale. As the reservoir level rises, part of the increase in horizontal thrust is transferred to the shale. Since the shale is relatively stiff and has a low hydraulic conductivity, the increase in loading is; therefore, transferred to the porewater, resulting in generation of excess porewater pressures in shale. When the reservoir is high a portion of the excess porewater pressure dissipates. The observed horizontal movement along the shear zone is then developed from elastic deformation and horizontal consolidation of the shale from dissipation of excess porewater pressure. An analytical model was developed from the proposed conceptual model and had general success predicting the horizontal displacement based on the reservoir level and time period. However, the model was sensitive to the reservoir level and several variables within the shale including the hydraulic conductivity and porewater parameter B. Overall, the material variables such as hydraulic conductivity and B can be refined; however, without having an accurate reservoir prediction into the future, the ability for this model to predict the displacement in the foundation will be limited.

First generation ethanol production has experienced rapid expansion but is now at a crossroads facing impending industry transformation. While Saskatchewan’s ethanol industry has benefited from demand and policy instruments that have guided substantial growth in recent years, changing policy and market dynamics present new challenges which are compelling the industry to adjust. This thesis examines three factors that are suspected to influence ethanol plant locational decisions. The development of an agent-based simulation model in this thesis will ascertain how transportation networks, market synergies, and subsidization influence location stability for an ethanol plant. The long term interaction of these factors is unknown, therefore do tradeoffs exist between these factors or is it conditional for all to be present? Modeling factors that affect location stability through an agent-based approach creates a dynamic framework to understand how location attributes impact an ethanol agent’s longevity. It was found that location stability is affected by an ethanol agent’s distance to both primary transportation networks as well as product markets. Surprisingly, distance to DDGS (dried distillers grain with solubles) markets, a low value by-product of ethanol production, has a profound effect on location stability. Policy instruments and industry subsidization are considered key ethanol development drivers and the surge in ethanol industry growth brought hopes of rural revitalization. In Saskatchewan, policy was developed to support small ethanol plants, those 25 Mmly (million litres per year) or smaller, aimed at increasing farmer investment and alternative markets for wheat. Measuring the effect of subsidization on location stability was fundamental to understanding how a post subsidized ethanol industry may look. The research found that subsidization of Saskatchewan’s ethanol industry dramatically affected economies of scale and location decisions, which left ethanol agents unable to compete in an increasingly competitive ethanol industry.

Water resources in Canada are of major environmental, social and economic value. It is expected that climate change will be accompanied by more intense competition for water supply in water-stressed agricultural areas such as the southern Prairies. Beyond physical impacts, drought can be seen as a socio-economic and political problem which ultimately has implications for community-level vulnerability to climate change. This thesis presents empirical vulnerability case studies focused on the exposure-sensitivity and adaptive capacity of Coronach and Gravelbourg in southern Saskatchewan. The results illustrate the fact that farmers or ranchers are not merely passive victims of drought. They also take an active role in shaping the environment around them, thus affecting their own vulnerability to drought. Therefore, by understanding the causal linkages of the coupled social-environment system, a more comprehensive understanding of community vulnerability is achievable and informed decisions can be made based on this thorough understanding of local conditions. In the second part of this thesis, the potential of soft water path is evaluated as a possible adaptation strategy. Based on the results gathered in the first part of this thesis, adaptation measures are tailored to address specific needs of different sectors in the Town of Coronach and the Town of Gravelbourg while ensuring ecological sustainability. Examples of possible paths (adaptation measures) are suggested in order to increase community adaptive capacity to water shortages in light of future climate changes.

The purpose of this study was to evaluate the sustainability of agroecosystems. The framework developed within this study is systems-based with the dynamic linkages between the system components explicit. The primary objective of the study was to develop a computer model, the Sustainable Agroecosystem Model (SAM), that dynamically integrates the economic and ecological components of an agroecosystem. The model was used to assess the sustainability of agroecosystems, defined by ecodistrict boundaries, in the Brown soil zone of southwestern Saskatchewan. The SAM was comprised of three components: (1) a soils model that simulated soil and crop growth parameters; (2) an economic model that simulated land use and cropping decisions; and (3) a habitat model that calculated habitat and biodiversity parameters. These components were largely self-standing models comprised of important processes of the soil, economic and ecological sectors of the agroecosystem respectively. To simulate the co-evolutionary changes of the agroecosystem the component models were dynamically linked, based on a one year time step, through selected input and output parameters. The output of the component models reflect elements of the natural and man-made capital stock of the target agroecosystems and were used as sustainability indicators. The concept of strong sustainability was adopted in the analysis such that changes in these indicators signal changes in the relative sustainability of the system. The study focused on two types of simulations: (1) the relative sustainability of four ecodistricts was assessed using baseline simulations. This analysis highlighted the importance of biophysical constraints to the sustainability of an agroecosystem. These simulations indicated that the development of production technologies and policy initiatives, targeting agroecosystem sustainability, should explicitly consider the regional biophysical constraints faced by farms; and (2) the relative sustainability of a single ecodistrict subjected to economic (carbon credit and carbon tax policies) and environmental (climate change) perturbations was evaluated. These simulations highlighted the difficulty in identifying a single policy that leads to a sustainable agroecosystem. In general, policies that resulted in improvement in some components of the capital stock caused degradation of other components. The Identification of preferred policy, in terms of agroecosystem sustainability, requires a weighting of system effects based on societal preferences, ethical responsibilities, degradation thresholds and system co-evolution.
