Abstract
Many problems in modern computing require a visual component. That is to say, it is fairly common for applications to have a need to see their environments. These applications will typically employ techniques designed specifically to solve the particular task needed for the application, and have little or no relation to the human visual system. Humans generally do not have difficulty interpreting the world around us. When traveling through known environments, we can easily recognize particular walls, doors and other objects in our view. We are not confused by the huge number factors that can complicate an image. The generalization and robustness of the human system would provide a huge benefit to any system that requires more advanced vision than is capable with the ad-hoc methods developed previously. If the underlying principles that make the human visual system so powerful can be identified and implemented programmatically, then a machine could reap the benefits obtained by humans. The purpose of this thesis is to demonstrate that a visual system modeled after the human visual system will be robust and accurate enough to solve real world problems - and to be useful in a non-trivial application. By developing neural networks that directly model the most primitive image processing cells of the human visual system, a platform can be built on which advanced vision systems can be developed.

Abstract
The highly conserved family of RNA-binding proteins known as the VICKZ RNA-binding proteins play an integral role in the formation of cytoplasmic RNPs which leads to the stabilization, localization and translational control of many mRNA transcripts in the cell. The key investigation of this thesis was to analyse the binding ability of the VICKZ protein family member, the coding region determinant-binding protein (CRD-BP), both in-vitro and in cells. CRD-BP has four K-homology (KH) domains and two RNA-recognition motif (RRM) domains. Deletion studies in CRD-BP orthologs have shown that the KH domains, and not the RRM domains, are predominantly responsible for binding to RNA substrates. However, it is still unclear to what extent each of the KH domains play in their physical interaction with RNA molecules, nor is it known if each of the KH domains an play equal role in interacting with different RNA substrates. In an effort to address the above questions, we used site-directed mutagenesis to mutate the first glycine of the G-X-X-G motif in each KH domain separately, and in combinations. We mutated the glycine to an aspartate to introduce both physical and electrostatic hindrance for binding at the G-X-X-G motif. The goal was to determine if such a mutation can disrupt CRD-BP's ability to bind its RNA substrates both in-vitro and in cells. Our results showed that KG single mutants KH2, KH3 and KH4 did not disrupt the CRD-BP-c-myc CRD RNA interaction in-vitro. CRD-BP KH1 single mutant exhibited a modest reduction in binding to the c-myc CRD RNA substrate in-vitro. However, double KH domain mutations (KH1-2, KH1-3, and KH2-4) resulted in a complete abrogation of CRD-BP's ability to bind the c-myc CRD RNA substrate, suggesting these KH domains work in tandem to bind to the c-myc CRD RNA substrate in-vitro. Interestingly, the CRD-BP KH domain double mutant, KH3-4, showed only a modest reduction in the c-myc CRD RNA substrate binding, suggesting that the first glycine in the G-X-X-G motif of KH3 and KH4 doe

Abstract
Highly active antiretroviral therapy (HAART) has significantly improved the health and well-being of many people living with HIV. Successful treatment with HAART requires a very high level of adherence, and continued engagement with health care services. Particular challenges to successful treatment with HAART exist in northern BC, but little research has been done in this region. This study investigated the experiences of those prescribed HAART who live in northern BC in order to identify what barriers and supports exist to optimal adherence, and engagement in HIV-related care. In-depth interviews indicated the complex and intersecting factors which affect adherence and engagement in care. Proximal, intermediate and distal social determinant of health which are relevant to adherence and engagement in HIV-related care were identified. Depression and stress, prioritization, and access to medications and care were identified as mechanisms in which various factors acted as barriers to adherence and engagement in care. --Leaf ii.

Abstract
Grade 1 is markedly the most challenging and exciting time in a child’s school experience. These children are no longer the youngest at school, and chances are they have gained an inch or two in height; in this sense, it is a year to feel big. This also marks a time of learning how to read, one of the biggest milestones during the Grade 1 school year. Learning to read is an essential, and fundamental, component of being a successful student, as it spans across all grades and all curriculum. Guided reading can serve as an effective and practical teaching program in order to effectively support students’ journey of developing reading proficiency. This project describes my development of a guided reading manual for Grade 1 teachers... .

Abstract
Resource companies in Canada operate in remote locations, often hours away from the closest municipality where emergency services such as police, fire and emergency medical services are located. People and equipment use low grade roadways to travel in and out of these locations and deal with the risks of incidents occurring. When an incident such as a motor vehicle collision does occur, the patient can be trapped in the wreckage for hours with no protection from the elements waiting for rescuers to arrive and provide critical interventions. Similarly, tank truck leaks and wildfires that start small can grow in size and severity without quick response actions from trained responders utilizing the appropriate equipment. We will investigate the frequency and severity of these and other incidents occurring in remote locations where resource companies are expanding into and evaluate whether the risks justify the commercial viability of a new service delivery. By analyzing the costs of these incidents to the resource companies in terms of injuries to humans and wildlife, environmental impact and also company reputation, we will see if there is a need for providing a more rapid response model. If the service is indeed justified, at what price point does it become palatable to the resource companies as they weigh the pros and cons of taking on additional costs. Our research will ask the question of the companies and then see if that pricing model will provide sufficient revenue to cover the costs to provide the service and provide a reasonable return on investment for the service provider. Some of the metrics used for the financial analysis will be payback periods to recoup the capital outlay, internal rates of return on the capital investment, and the net present value of the future revenues that are projected to be generated. At the conclusion of the study we can make an informed decision as to whether this venture is truly a wise investment of time, money, and manpower or if the return on investment is not worth the

Abstract
This qualitative analysis examines the effects of gainsharing on both productivity and employee engagement in the British Columbia pulp and paper industry. The pulp and paper industry plays an important role in the provincial economy by contributing four billion dollars annually and employing over 10,000 workers in high-pay unionized jobs. However, the industry has seen a significant decline in the past ten years in the number of facilities operating, which has reduced employment and ultimately tax revenue in the province. The economic importance of the pulp and paper industry highlights the need for unions and management to work together. Management must engage the human capital of its employees in order to achieve a competitive advantage in the global market. Gainsharing is a means to increase productivity more importantly, it is a method of facilitating a cooperative relationship between unions and management. This cooperative relationship not only increases productivity, but also significantly reduces labour relations costs while promoting a sense of satisfaction, loyalty and commitment within the employees. In this project, I develop a model explicitly outlining the impact of gainsharing within the pulp and paper industry. I test the model by reviewing and summarizing existing literature. The results are strongly supportive of the positive impact of gainsharing on productivity, reduced labour relations costs, employee engagement and profitability. I present recommendations for the application for government involvement, which can contribute to the success of this process, thus contributing to the success of the pulp and paper industry. --P. 2.
