An empirical clarification of motivational variables among Saskatchewan people of Indian ancestry

Harding, David James 15 July 2008 (has links)
A lack of reliable knowledge regarding the problems facing Indian and Metis people has hindered the development of intelligent programs and policies to facilitate their healthy integration into the larger Canadian society. Two large scale studies (Hawthorn, Belshaw, & Jamieson, 1958; Lagassé, 1959) have attempted to alleviate this problem by collecting extensive data on such aspects of Indian and Metis life as the community and family, resources, employment, education, relations with the law, social welfare needs, liquor and administration.<p> These broad studies dealt only indirectly with Indian and Metis philosophies, personalities and modes of thought, areas in which a comprehensive understanding will have to be achieved to thoroughly comprehend the nature of the problems facing people of Indian ancestry. The Hawthorn study stressed that other research which might follow should include topics such as those which lie within the vast area of psychology.

Adaptive governance for fire management planning : a case study on Prince Albert National Park, Saskatchewan

Almstedt, Ǻsa 25 November 2010 (has links)
Fire is a natural ecological process in the boreal forest, but also a threat to human lives, properties and other values at risk. The challenge is to find a way to manage fire where both the positive and negative aspects of fire are effectively balanced. This is especially important since more frequent and intense wildfires are predicted in the future due to climate change. There is also a need for increased cooperation across jurisdictions to improve the efficiency and effectiveness of Canadian fire management. To address the current and future challenges of fire management, this thesis argues that an effective and adaptive governance approach is needed.<p> The purpose of the study was to develop principles, criteria and indicators of adaptive governance and to apply this framework to fire management planning in Prince Albert National Park (PANP), Saskatchewan. Because of the need to include other agencies with fire responsibilities, the study also focused on the interagency cooperation with Saskatchewan Environment (SE), the provincial ministry responsible for wildfires.<p> Principles, criteria and indicators of adaptive governance were identified based on literature on good governance, adaptive management, adaptive governance, and wildfire specific literature. A qualitative research approach was then used to collect data mainly through semi-structured interviews with representatives from Parks Canada (both from PANP and at the national level) and SE, and document analysis of fire plans and strategies.<p> This study shows that many aspects of adaptive governance have already been implemented in PANP, so that principles and criteria of inclusiveness, legitimacy, foresight, leadership, and many aspects of performance-oriented and adaptiveness have been at least partially met. Yet, there is a need to improve information-sharing and communication, especially across jurisdictions. In terms of the interagency cooperation between PANP and SE, having different mandates is the biggest challenge, but it does not prevent cooperation. Throughout the years both agencies have worked out ways to deal with differences in their mandate and fire management strategies. Having a dialogue to try to understand each other�s mandate and respect each other has been and continues to be a key factor in the cooperation. Finally, maintaining and retaining social capital may be crucial to future success in fire management planning, both from an intra- and from an interagency perspective.

Tradition and innovation: official representations of Queen Victoria and Prince Albert by Franz Xaver Winterhalter

Barilo von Reisberg, Eugene A. January 2009 (has links)
The thesis focuses on four sets of official portraits of Queen Victoria and Prince Albert, which were painted by the German-born elite portrait specialist Franz Xaver Winterhalter (1805-1873) between 1842 and 1859. These portraits are examined in detail and are placed within the contexts of the existing scholarship on Franz Xaver Winterhalter, British portrait painting of the 1830s and 1840s, and the patronage of portraiture in Britain during the reigns of William IV and Queen Victoria. The thesis compares and contrasts these works with official representations of Queen Victoria and her husband by British artists; and examines the concept of “gender reversal” within the accepted notion of marital pendants by highlighting Winterhalter’s innovations in the genre of official portraiture.The thesis challenges the perception that Winterhalter’s employment at the court of Queen Victoria was due to the Queen’s alleged penchant for “all things German” by placing Winterhalter’s portraits within the context of the British Royal Collection. It examines the reasons for the artist’s success at the British court, accentuating among others Winterhalter’s ability to conceptualise in his portraits of Prince Albert the hierarchically-complex position of the Prince Consort. The overarching arguments of the thesis focus on two propositions - that by employing a foreign artist as her official image maker, Queen Victoria acquired ultimate control over the production, distribution and popularisation of her own imagery; and that this patronage is illustrative of the emergence of a royal and aristocratic international iconography that overrode the competing concept of ‘national’ schools of art.

Hydrocarbon potential of the Prince Albert Formation, Ecca Group in the main Karoo Basin, South Africa.

Mosavel, Haajierah January 2020 (has links)
Philosophiae Doctor - PhD / This thesis focusses on the hydrocarbon potential of the Prince Albert Formation in terms of its shale gas potential. Unconventional gas production from hydrocarbon-rich shale formations, known as “shale gas”, is one of the most rapidly expanding trends in onshore oil and gas exploration and exploitation today. In South Africa, the southern portion of the main Karoo Basin is potentially favourable for shale gas accumulation and may become a game changer in the energy production regime of the country. The Prince Albert Formation was selected for research, since previous studies in South Africa have focused on shale from the Whitehill Formation, which together with the underlying Prince Albert Formation, occur within the lower Ecca Group in the main Karoo Basin. The petrophysical properties and shale gas potential of the Prince Albert Formation was determined using the parameters of mercury porosimetry, total organic carbon (TOC), vitrinite reflectance, Rock-Eval and residual gas measurements. The lithostratigraphy, rock classification, and depositional environment of the Prince Albert Formation, together with the adjacent parts of the overlying Whitehill Formation and underlying Dwyka Group within the southern part of the main Karoo Basin were addressed. Rock types were characterised using X-ray fluorescence (XRF), X-Ray diffraction (XRD) and statistical analysis. Geochemical proxies and stable isotopes (δ18O, δ13C and δ15N) were used to identify the depositional environment. Additionally, the Dwyka Group, Prince Albert and Whitehill formations were correlated with equivalent Southern Gondwanaland units to understand basin development. The results of the shale gas study of the Prince Albert Formation showed porosities ranging between 0.08 and 5.6%, permeabilities between 0 and 2.79 micro-Darcy, TOC between 0.2 and 4.9 weight % and vitrinite reflectance values between 3.8 to 4.9%. Rock-Eval analysis indicated that the kerogen in the shale was Type III and IV and hydrogen indices were less than 65 mg/g. Free or absorbed gas was not detected in the recently drilled boreholes KZF-01 and KWV-01 used in this study. It is probable that the absence of gas is a result of overmaturity due to tectonic duplication in KZF-01 and thermal degassing associated with dolerite intrusions in KWV-01. Although the porosity and TOC values of the Prince Albert Formation shales across the southern part of the main Karoo Basin are comparable with, but at the lower limits of, those of the gas-producing Marcellus shale in the United States (porosities between 1 and 6% and TOC between 1 and 10 weight %), the high vitrinite reflectance values indicate that the shales are overmature with questionable potential for generating dry gas. A comprehensive rock classification were compiled for the Prince Albert Formation, which consists of shale and minor ferruginous shale ranging between thicknesses of 30 and 168 m based on field work and core descriptions. Mineralogical, geochemical and statistical data, classified collected samples as Fe-shale, phosphatic shale, manganiferous shales, shale, wacke, Fe-sand and litharenite. In unconventional resources, understanding the depositional environment is important in delineating the depositional process and bottom water conditions. The Prince Albert Formation was interpreted as marine forming under dysoxic to euxinic conditions. δ 13C values range between -17.5 and -23.1 ‰ and δ 15N between 8.5 and 11.1 ‰ reflecting marine conditions. Sediments of the Prince Albert Formation were interpreted as middle to outer continental shelf deposits based on various lithologies identified and XRF data (geochemical proxies). Compiled literature of the karoo- type basins in Southern Gondwanaland provides a correlation of the Dwyka Group, Prince Albert and Whitehill formations in South Africa. Based on stratigraphy and radiometric dating, the Dwyka Group, Prince Albert and Whitehill formations have been correlated with lithostratigraphic units in the Falkland Islands, Namibia (Huab, Karasburg and Aranos basins), the Ellsworth Basin of Antarctica and the Sauce Grande and Parana basins of South America. This correlation suggest that the main Karoo foreland system was subjected to very similar tectonic influences present in the other karoo-type basins of Southern Gondwanaland. In conclusion, results from this research indicate that viable conditions for shale gas might exist within the “sweet spot” areas constrained by formation thickness being > 30 m, relative dolerite intrusion of < 20%, relative total organic carbon content > 4 weight %, and maturity of < 3.5%. It is essential that new exploration boreholes be drilled within the “sweet spot” areas to test whether the lower Ecca Group (Prince Albert and Whitehill formations) has the potential to generate viable shale gas.

Analysis of airborne flux measurements of heat, moisture and carbon dioxide, and their correlation with land cover types in BOREAS

Ogunjemiyo, Segun Ojo. January 1999 (has links)
The landscape of the boreal forest in north-central Canada is characterised by mosaics of broad-leaved deciduous trees (aspen, Populus; birch, Betula), evergreen conifers (black spruce, Picea mariana; jack pine, Pinus banksiana; and larch, Larix), fens and lakes. The forest has been cited as the possible location of a global carbon sink, and its likely response in the event of global climate change remains unclear. To improve our current understanding of the links between the boreal forest ecosystem and the lower atmosphere, the Boreal Ecosystem-Atmosphere Study (BOREAS) was executed in a series of field experiments in 1994 and 1996. This thesis documents the efforts made to characterise and map temporal and spatial distributions of the fluxes of heat, water vapour and CO2 over two 16 km x 16 km heterogeneous sites at the BOREAS study sites. / Most of the data in this thesis were obtained from the airborne observations by the Canadian Twin Otter Aircraft, operated by the Institute for Aerospace Research of the Canadian National Research Council, at the BOREAS Northern Study Area (NSA), and Southern Study Area (SSA). The research aircraft was flown at a fixed altitude of about 30 m agl. The data acquired in 1994 were primarily used to develop an objective deterending scheme in eddy-correlation flux estimates, that took into consideration the physical nature of turbulent transport during convective daytime conditions, and to map the spatial distribution of sensible heat, latent heat and CO2 fluxes over three intensive field campaigns. Maps of spatial patterns of the surface characteristics, such as the surface temperature excess over air temperature (Ts-T a) and Greenness index (GI), were also constructed. The mapping procedure involved generation of an array of grid points by block averaging the parameter of interests along the flight lines, spaced 2 km apart, over 2 km windows, with 1 km overlap between adjacent windows. The (Ts-Ta) maps showed, not surprisingly, that surface temperatures were relatively cooler over the mature forests than over the disturbed, regenerating and burn areas. However, they also showed a decoupling between sensible heat flux and T s-Ta not seen in less complex terrain. By contrast, close correspondence was observed between maps of CO2 flux and greenness, suggesting that the potential to infer CO2 exchange from remote sensing observations of the surface is higher than that for energy exchange.

Flux associations and their relationship to the underlying heterogeneous surface characteristics

Brown Mitic, Constance Maria. January 1999 (has links)
This thesis consists of analysis of three different data sets: (i) Aircraft-based eddy correlation data collected above irrigated and non-irrigated agricultural land in Southern California during the California Ozone Deposition Experiment (CODE) summer 1991; (ii) micrometeorological tower data, collected over grape and cotton canopies as part of CODE; (iii) aircraft-based eddy correlation flux data above two grid sites in the Canadian boreal forest during the Boreal Ecosystem-Atmosphere Study (BOREAS), spring and summer of 1994 and 1996. / Results from the CODE aircraft data document composition and size of the dominant structures, which transport heat and gases (H2O, CO 2 and ozone) over water stressed and non-water stressed surfaces, and the relative frequency with which structures carrying only a single scalar, or given combinations of scalars, were encountered along the flight paths. Interpretation of results provides further evidence for the existence of a second (nonphysiological) sink for ozone. The relative preponderance of structures that carry moisture, carbon dioxide and ozone simultaneously, particularly in the gradient-up mode, reflects the importance of vegetation as co-located source/sink for these scalars. The detrending procedures described in this study may help to define a more effective separation between local and mesoscale events in biosphere-atmosphere interaction. / Results from the CODE tower data indicates a single vegetated ozone sink for the grape site, but a vegetated as well as a non-vegetated sink for the cotton site. For both sites, structures simultaneously transporting significant flux contributions of CO2, H2O, heat and ozone dominate during unstable conditions. During stable conditions, unmixed single flux structures dominated over cotton but not over grape. The results of this study contribute empirical evidence about the relationship between ozone uptake and the physical and physiological state of vegetation, as well as the limitations placed on eddy scales in simulation models. / Results from the BOREAS aircraft data shows a decoupling between the surface and the atmosphere, where the patterns of vegetation, greenness and surface temperature may be quite dissimilar to those of the fluxes of sensible heat, latent heat and---to a lesser degree---CO2. Reasons for this lie in the extraordinary boundary layer conditions, high vapour pressure deficit, moist soil and hot canopies, and the response of the vegetation to these conditions. Analysis of the coherent structure compositions to some extent permits the characterization of the different sources and sinks. Overall, this study shows the importance of understanding the various interacting components of soil, vegetation and atmosphere when attempting to design process-based models for predictions in 'micrometeorologiacally' complex ecosystems.

At the edge : the north Prince Albert region of the Saskatchewan forest fringe to 1940

Massie, Merle Mary Muriel 18 January 2011
Canadians have developed a vocabulary of regionalism, a cultural shorthand that divides Canada into easily-described spaces: the Arctic, the Prairies, the Maritimes, and Central Canada, for example. But these artificial divisions obscure the history of edge places whose identity is drawn from more than one region. The region north of Prince Albert, Saskatchewan, is a place on the edge of the boreal forest whose self-representations, local history, and memorials draw heavily on a non-prairie identity. There, the past is associated with the forest in contrast to most Canadians' understanding of Saskatchewan as flat, treeless prairie. This dissertation presents the history of the north Prince Albert region within a framework that challenges common Saskatchewan and Canadian stereotypes. Through deep-time place history, layers of historical occupation in the study region can be compared and contrasted to show both change and continuity. Historical interpretations have consistently separated the history of Saskatchewans boreal north and prairie south, as if the two have no history of interchange and connection. Using edge theory, this dissertation argues that historical human occupation in the western interior found success in the combination of prairie and boreal lifeways.<p> First Nations groups from both boreal forest and open plain used the forest edge as a refuge, and to enhance resilience through access to resources from the other ecosystem. Newcomer use of the prairie landscape rebranded the boreal north as a place of natural resources to serve the burgeoning prairie market. The prairies could not be settled if there was not also a nearby and extensive source for what the prairies lacked: timber and fuel. Extensive timber harvesting led to deforestation and the rise of agriculture built on the rhetoric of mixed farming, not King Wheat. The mixed farming movement tied to landscape underscored the massive internal migrations from the open prairies to the parkland and forest edge.<p> Soldier settlement, long viewed as a failure, experienced success in the north Prince Albert region and gave a model for future extensive government-supported land settlement schemes. South-to-north migration during the 1920s was based on a combination of push and pull factors: drought in the Palliser Triangle; and a strengthening northern economy built on cordwood, commercial fishing, freighting, prospecting and fur harvesting, as well as mixed farming. The economy at the forest edge supported occupational pluralism, drawing subsistence from both farm and forest, reflecting the First Nations model. As tourism grew to prominence, the Saskatchewan dual identity of prairie/forest led to the re-creation of the north Prince Albert region as a new vacationland, the Playground of the Prairies. The northern forest edge drew thousands of migrants during the Great Depression. Historical analysis has consistently interpreted this movement as frantic, a reactionary idea without precedent. Through a deep-time analysis, the Depression migrations are viewed through a new lens. The forest edge was a historic place of both economic and cultural refuge and resilience predicated on the Saskatchewan contrast of north and south.
