Stolen past: Shattered futures, aboriginal justice in Canada

It is acknowledged that Canada's criminal justice system has some major flaws, particularly with respect to its application to various ethnic subgroups. Aboriginal Canadians are one subgroup particularly sensitive to the problems in the system as is reflected by their disproportionately high rates of criminality and incarceration. Over the past 50 years many programs have been developed and recommendations have been made to alleviate the tensions Aboriginals find within the system. However, the situation today is essentially the same. Aboriginals are still overrepresented within the system and solutions that have been brought forward have had little success in stemming their flow into the system. Blame for Aboriginal mistreatment in the system has been placed at all levels from line police officers to high-level officials and politicians and attempts to resolve problems continue as an on going process. However, many of the recommendations and reforms have revolved around culture conflict. Although this thesis recognizes the importance of culture conflict in the overrepresentation of Aboriginals within the Canadian criminal justice system, it has also recognized that culture conflict alone is not responsible for all the flaws within the system as it pertains to Aboriginals. This thesis is of the opinion that in order for reforms to the criminal justice system to be successful, the context in which the system is operating must also be considered. Variables such as geographic isolation, economic disparity and social/political stability are viewed as operating in conjunction with culture, ultimately influencing Aboriginal treatment within the system. The conclusions drawn from this study confirm that when these factors operate together, the overrepresentation of Aboriginals within the Canadian criminal justice system is inevitable. Thus all three variables, culture conflict (social/political stability being part), geographic isolation and economic disparity must be address within the system if any significant changes in the crime rates or incarceration rates of Aboriginals is to be expected. In addition, primary research indicated the influence of cooperation as a factor in moderating the effects of criminality; not just cooperation among Aboriginals and non-Aboriginals, but also cooperation among differing Aboriginal communities. It was argued that when all these issues are addressed, Aboriginal peoples in Canada will have the strength to repair their shattered futures.

Investigating the potential of thecamoebians (testate amoebae) as bio-indicators of impact of oil sands mining operations on freshwater environments in Northeastern Alberta, Canada

Thecamoebian (testate amoeba) species diversity and assemblages in reclamation wetlands and lakes in northeastern Alberta respond to chemical and physical parameters associated with oil sands extraction. Ecosystems more impacted by OSPM (oil sands process-affected material) contain sparse, low-diversity populations dominated by centropyxid taxa and Arcella vulgaris. More abundant and diverse thecamoebian populations rich in difflugiid species characterize environments with lower OSPM concentrations. These shelled protists respond quickly to environmental change, allowing year-to-year variations in OSPM impact to be recorded. Their fossil record thus provides corporations with interests in the Athabasca Oil Sands with a potential means of measuring the progression of highlyimpacted aquatic environments to more natural wetlands. Development of this metric required investigation of controls on their fossil assemblage (e.g. seasonal variability, fossilization potential) and their biogeographic distribution, not only in the constructed lakes and wetlands on the oil sands leases, but also in natural environments across Alberta.

Integrating vitrinite reflectance, rock-eval pyrolysis, flourescence microscopy and palynology of the Athabasca oil sands, Kearl Lake area, northeastern Alberta

Three cores from the Kearl Lake Oil Sands area within the Athabasca deposit of northeastern Alberta have been analyzed to understand the thermal history of the McMurray and Clearwater formations of the Lower Cretaceous Mannville Group. The approach involves the integration of vitrinite reflectance (VR), Rock-Eval pyrolysis, fluorescence microscopy, and palynology. Mean VR varies between 0.21 and 0.43% Ro and indicates thermally immature levels equivalent to the rank of lignite to sub-bituminous coal. Although differing lithologies have influenced VR to some extent (i.e., coals and bitumen-rich zones), groundwater influence and oxidation seem not to have measurably altered YR. Rock-Eval analysis points to Type III/IV kerogen, and samples rich in amorphous organic matter (ADM) show little to no fluorescence characteristics, implying a terrestrial source of origin. Palynology reveals the presence of some delicate macerals but lack of fluorescence and abundant ADM suggests some degradation and partial oxidation of the samples.

A stochastic dynamic programming approach for pricing options on stock-index futures

The aim of this thesis is to price options on equity index futures with an application to standard options on S&P 500 futures traded on the Chicago Mercantile Exchange. Our methodology is based on stochastic dynamic programming, which can accommodate European as well as American options. The model accommodates dividends from the underlying asset. It also captures the optimal exercise strategy and the fair value of the option. This approach is an alternative to available numerical pricing methods such as binomial trees, finite differences, and ad-hoc numerical approximation techniques. Our numerical and empirical investigations demonstrate convergence, robustness, and efficiency. We use this methodology to value exchange-listed options. The European option premiums thus obtained are compared to Black's closed-form formula. They are accurate to four digits. The American option premiums also have a similar level of accuracy compared to premiums obtained using finite differences and binomial trees with a large number of time steps. The proposed model accounts for deterministic, seasonally varying dividend yield. In pricing futures options, we discover that what matters is the sum of the dividend yields over the life of the futures contract and not their distribution.
