2014 — Evaluation of Contaminant Containment at Regina LandfillRésumé
Landfill and waste containment facilities are routinely constructed on natural or engineered low permeability barriers placed above or within the vadose zone to prevent contaminant migration into the groundwater system. Numerical estimates of design lives for assessment of barrier system performance are generally acceptable under numerous landfill regulations. Predictive models work under the general assumption that constructed systems will retain their structural integrity over the design life of the landfill and act as leak proof systems. Contrary to the above assumption, barrier performance, whether natural or engineered, at countless landfills and waste disposal sites across North America suggests that these … Lire la suite

2020 — Genomics-Based Characterization of the Microbial Community and Plasmidome of the Regina Wastewater Treatment Facility and the Surrounding Aquatic EnvironmentRésumé
Wastewater produced from human activity contains high concentrations of contaminants like ammonia, pathogens, and organic compounds with high biological oxygen demand; all of which must be remediated with proper wastewater treatment prior to discharge into the environment. Most large-scale wastewater treatment plants (WWTPs) remove contaminants from wastewater using the activated sludge process, wherein wastewater is mixed with a flocculent slurry of microorganisms that use these contaminants for the production of energy or increasing microbial biomass. The activated sludge environment is a complex microbial ecosystem, containing stable populations of organisms adapted to activated sludge, as well as transient environmental and human … Lire la suite

2018 — Summer Science Camp Instructor Reflections on Personal and Professional DevelopmentRésumé
The purpose of this research was to ascertain how the summer job experiences at the EYES (Educating Youth in Engineering and Science) program impacted former instructors’ personal and professional development. Science, technology, engineering and math (STEM) educational research in a camp environment is mostly focused on student learning and achievement; my research instead focused on the impact on and outcomes for the program instructors, who develop and deliver the educational material for children. The EYES program is a not-for-profit organization based at the University of Regina. It has a mission of sparking curiosity and developing a lasting interest in science, … Lire la suite

2016 — The pollination biology of Haskap (Lonicera caerulea L.: Caprifoliaceae): floral traits and pollinator performance of a new Saskatchewan fruit crop.Résumé
Haskap (Lonicera caerulea L.) is an early flowering fruiting shrub native to northern regions of Europe, Asia and North America. Commercial growth began in Europe and Asia over a century ago, but it has only recently been cultivated in North America. It is self-incompatible, and requires insect pollinators in order to set fruit; however, very little is currently known about its pollination biology, including associated pollinators and important floral characteristics. My research compared the pollinating performance of three groups of bees on Haskap: commercial Apis mellifera and Osmia lignaria, and wild Bombus spp. I found that Bombus queens had the … Lire la suite

2012 — First Time Users of Therapist-Assisted Internet Cognitive Behaviour Therapy: A Qualitative Examination of Psychology Graduate Students in TrainingRésumé
Depression and anxiety are the most commonly experienced mental health conditions in Canada. Research has shown that one of the significant factors in the under-treatment of mental health conditions is a lack of access to providers. Researchers have begun to create novel ways to address the problem of a lack of access to mental health services, such as offering Therapist-Assisted Internet Cognitive Behaviour Therapy (TAICBT). This involves clients reviewing psychoeducational information on the use of cognitive and behavioural strategies for coping with a mental health condition over the Internet. This is combined with communicating with a therapist who provides support … Lire la suite

2015 — A Randomized Controlled Trial of Internet-Delivered Cognitive Behaviour Therapy for Individuals with FibromyalgiaRésumé
Fibromyalgia (FM) is a condition that affects approximately 1,050,000 Canadians. Symptoms of depression and/or anxiety are present in up to three quarters of individuals with FM. A large percentage of individuals with FM, however, fail to seek psychological treatment for these symptoms, suggesting the need for the development of more accessible treatment methods, such as Internet-delivered cognitive behaviour therapy (ICBT). There has been limited research on the use of ICBT for FM and no research within the Canadian context. The focus of the current study was to assess the efficacy of the Pain Course, an ICBT program originally developed for … Lire la suite

2022 — Using Citation Network Analysis to Examine the State of Peer-Reviewed Perceptual-Cognitive Training Literature with a Research Focus on NeurotrackerRésumé
Computer based perceptual-cognitive training is an increasingly popular tool in performance improvement applications yet the academic link between computer training and real-world performance results is tenuous at best. Many commercially available products forge ahead without academic research supporting their product. One perceptual-cognitive training program, NeuroTracker, has differentiated itself by basing its development in academic research. This has resulted in wide use of the program around the world. NeuroTracker holds a leading role in perceptual-cognitive training and this thesis examines the peer-reviewed NeuroTracker literature through citation network analysis to discover the current state of the research. Citation network analysis is a … Lire la suite

2015 — Improvements and enhancements of mps in free surface flow simulation.Résumé
The grid-based Eulerian methods have dominated the CFD (Computational Fluid Dynamics) for decades due to its simplicity. The grids not only used for discretize the simulation domain but also used for the computation, however, due to the inherent disadvantages of the grid-based Eulerian method, the free surface flow cannot be simulated successfully without special numerical techniques. Recently, another numerical approach has been developed for hydraulic simulation, namely, the particlebased Lagrangian approach. In this approach, the domain discretization as well as the simulation procedure differs from traditional Eulerian approach. gridless methods are typical Lagrangian based method, the basic simulation elements used … Lire la suite

2012 — Reducts and Rough Set AnalysisRésumé
Rough set theory offers a mathematical approach to data analysis and data mining. It can be used to learn classification rules that define classes of a classi- fication based on some well defined concepts. The fundamental task of rough set data analysis is to precisely construct and interpret concepts. When applying rough set theory to rule learning, the main tasks involve removing redundant attributes, redundant attribute-value pairs, and redundant rules in order to obtain a minimal set of simple and general rules. Following Pawlak, we can arrange these tasks into a three-step sequential process, called Pawlak three-step approach, based on … Lire la suite

2014 — Living a Curriculum of Tensions: Experiences of Learning to Teach Physical EducationRésumé
This narrative inquiry explored two pre-service teachers’ experiences of learning to teach Physical Education during a 16-week internship. My interest emerged from my experiences as a student, pre-service teacher, teacher, cooperating teacher, supervising faculty, and teacher educator. I began by inquiring into my own stories of experience. Wonders emerged as I explored literature about learning to teach and juxtaposed a Deweyan conception of experience with other research paradigms such as post-positivism, Marxism, and post-structuralism. While traversing these borderland spaces and inquiring into my own stories of experience, a research puzzle was named: how learning to teach is experienced by pre-service … Lire la suite
