2014 — Effect of Emotion Regulation Strategies on the Pain ExperienceRésumé
Pain, an unpleasant subjective and multidimensional experience associated with actual or potential tissue damage, is fundamentally a psychological phenomenon with emotional components. As such, the multi-component coordination of processes by which emotions are moderated, emotional regulation (ER), is of particular interest. Two primary ER strategies are reappraisal and suppression. Few studies have explored the effects of suppression and reappraisal on pain outcomes. The purpose of this study was to examine: 1) differences among suppression, reappraisal, and monitoring-control experimental conditions (i.e., conditions involving verbal instruction to engage in specific ER strategies) on indicators of pain and affect; 2) the relationship between … Lire la suite

2014 — Lifestyles of the Poor and CelibateRésumé
Jesuits are members of the Society of Jesus, an organization of Catholic priests and Brothers. Through their roles as ritual, political, and educational leaders in the Catholic Church, Jesuits in English-speaking Canada participated in building up and maintaining a Catholic moral cosmos. But together with the non-Jesuits with whom they worked closely, Jesuits were also engaged in deliberate, intensive moral work on themselves, often explicitly attending to freedom, sincerity, and the personal appropriation of a range of dispositions and ideas deemed to be properly “Jesuit.” Morality, understood here as the socially laid axes along which persons evaluate themselves and the … Lire la suite

2014 — As Iron Sharpens Iron: Understanding Competitive Processes in Elite Sport TeamsRésumé
The purpose of this thesis was the exploration, definition, conceptualization, and measurement of competition within elite sport teams (i.e., intrateam competition) by using an exploratory sequential mixed-methods design (Creswell, 2006). In Study 1, intrateam competition from coaches’ perspectives was examined. It revealed two distinct competitive processes: situational competition and positional competition. Situational competitions are planned competitive situations that occur during practice (e.g., scrimmages). Positional competition is the vying for the same limited playing time by teammates in the same position. The latter was examined further. In Study 2, athletes’ perspectives of positional competition were explored. The results showed that positional … Lire la suite

2014 — Population Aging and Long-Term Care Policy Change in Canada: A Comparison of British Columbia, Manitoba, and OntarioRésumé
Introduction: Residential long-term care (LTC) is an important component of the care continuum for older adults in Canada. Three factors related to population aging are contributing to an increased demand for LTC services: 1) an increased prevalence of age-related health disorders; 2) reduced societal capacity to provide unpaid care; and 3) a lack of available substitutes for LTC. LTC is not one of Medicare’s insured services and as such great variation in the provision of LTC services exists across provinces. Provincial governments are currently grappling with how best to provide and pay for quality LTC services while also weighing investment … Lire la suite

2014 — Generating Newness: The Third Space Modality in The Buddha Of Suburbia, Fruit of the Lemon and White TeethRésumé
In The Location of Culture, Homi Bhabha introduces his concepts of the third space, in-between spaces, the beyond and hybridity to explore how subordinated people – including colonized people, minorities and migrants – resist the dominant group’s power and generate newness. Newness, as presented by Salman Rushdie in The Satanic Verses, is difference that derives from immigration and hybridity, specifically, constructive changes in the way people think and behave in relation to immigration, hybridity, culture and people of colour. By examining Bhabha’s concepts in relation to the identity crises of four fictional second-generation immigrants of colour – Karim Amir in … Lire la suite

2014 — Determining the Impact of Telehealth on Rural and Remote Health Care Service Delivery in CanadaRésumé
There are disparities in health status and outcomes between rural and remote residents and their urban counterparts, and these disparities are caused in part by inequitable access to health services. For decades provincial and territorial decision makers have implemented numerous health human resource policies, most commonly financial incentives, to attract health providers to rural and remote areas to alleviate the inequity of access. The effect of these policies has been temporary in that health providers responding to these incentives rarely established permanent practices in rural and remote communities. In addition, these policies rarely address the fact that specialized health services … Lire la suite

2014 — Structured Rough Set ApproximationsRésumé
Rough set theory is widely used in many areas, such as artificial intelligence, machine learning and data mining. Lower and upper approximations are two fundamental notions for concept analysis with rough set theory. In rough set theory, one can obtain two kinds of sets in an information table, namely, definable and undefinable sets. Intuitively, a definable set represents some- thing we can describe precisely. On the other hand, for an undefinable set, one cannot describe it precisely due to limited available information. One of the main issues in rough set theory is to approximate an undefinable set by a pair … Lire la suite

2014 — Analysis of Impact Factors for Traffic Noise in urban AreasRésumé
Road traffic noise contributes significantly to outdoor environmental noise, especially in urban areas. The pressure of traffic noise is influenced by many factors such as types of engines, exhaust systems and tires interacting with the road, weather and road conditions. The tire/pavement interaction noise has been proven to be the major source of the traffic noise, especially for cruising driving conditions, which is highly influenced by surface characteristics of road pavement. Traffic flow is also a factor – apart from vehicles, tires and road surface characteristics – in affecting traffic noise pressures. The noise level can increase by about 3 … Lire la suite

2014 — “About Average” A Pragmatic Inquiry into School Principals’ Meanings for a Statistical Concept in Instructional LeadershipRésumé
This mixed methods, sequential, exploratory study addresses the problem, “How significant are statistical representations of ‘average student achievement’ for school administrators as instructional leaders?” Both phases of the study were designed within Charles Sanders Peirce’s pragmatic theory of interpretation. In the first, phenomenological phase, 10 Saskatchewan school principals were each interviewed three times and invited to read aloud three different student achievement reports. Principals generally held a “centre-of-balance” conception for the average, which related to perspectives deriving from their organizational position. Abductive reasoning, a proclivity to act upon “below average” student achievement, leadership through asking leading questions, an inquiry cast … Lire la suite

2014 — Thermodynamic and Experimental Studies of Ethane Solubility in Promising Ionic Liquids for CO2 CaptureRésumé
Natural gas is one of the world’s major energy sources and the demand has increased remarkably in recent years. The production of natural gas often requires treatment processes in order to separate CO2 and H2S. CO2 must be removed in order to meet the heating value specifications for sales gas, whereas H2S is removed due to its toxicity and to reduce the overall release of SO2 into the atmosphere during combustion. Ionic liquids have recently been considered the most economically and environmentally friendly solvents for natural gas sweetening. This research aimed at measuring the solubility of C2H6 in six room … Lire la suite

2014 — Enhanced Solvent Vapour Extraction processes in Thin Heavy Oil ReservoirsRésumé
Solvent-based techniques, such as solvent vapour extraction (VAPEX) and cyclic solvent injection (CSI), have emerged as promising processes to enhance heavy oil recovery. However, there are still a number of technical issues with these processes, such as the theoretical modeling and performance enhancement. This thesis aims at addressing the following major technical topics. Theoretical modeling of VAPEX. Heavy oil−solvent transition zone is where the VAPEX heavy oil recovery occurs. Existing analytical VAPEX models can neither fully characterize the transition zone nor accurately predict its growth. Numerical simulation models use grid sizes that are much larger than the transition-zone thickness (~1 … Lire la suite

2014 — Limiting Operations for Quantum Random Variables and a Quantum Martingale Convergence TheoremRésumé
This thesis builds on the notion of quantum, or operator valued, probability as discussed in Farenick, Plosker, and Smith (J. Math. Phys, 2011) as well as Farenick and Kozdron (J. Math. Phys, 2012) by generalizing classical limiting results to the quantum setting. Mimicking the classical setting, we prove a continuity of quantum expectation result, which is the quantum analogue of Lebesgue's dominated convergence theorem and use it extensively to prove other limiting results. With the quantum limiting results in place, we de ne a quantum martingale and prove a quantum martingale convergence theorem. This quantum martingale theorem is of particular … Lire la suite

2014 — Healing Through Justice: The Application of Holistic Healing to Racialized and Sexualized Violence against Aboriginal Women of SaskatchewanRésumé
Over the last three decades, feminist research has brought violence against women to the attention of policy makers and the general public. In more recent years, researchers have begun to explore the intersection of race, colonialism and gender when examining the issues of violence against Aboriginal women and women of colour (Brownridge 2009, 164-200; Dylan, Regehr, Alaggia 2008, 678-696; Razack 2002, 123-156; 1998, 56-87; Smith 2005, 7-33; Stevenson 1999, 49-80). Aboriginal women in Canada experience exponentially higher rates of violence than non-Aboriginal Canadians do (Amnesty International 2004, 23; Johnson 2006, 14; Sinha 2013, 19). Further, Aboriginal women’s mortality rates as … Lire la suite

2014 — Dynamic and Static CO2 Mass Transfer Processes in Bulk Heavy Oil and Heavy Oil Saturated Porous MediaRésumé
In the petroleum industry, the contribution of solvents to the production of oil has become more cardinal, as production from the reservoirs have advanced from primary oil production to secondary and tertiary methods. Vapour extraction (VAPEX), CO2 flooding, CO2 Huff-and-Puff are some of the solvent based approaches used in the industry to enhance oil recovery performance. These methods involve the injection of a vaporized solvent into the reservoir in order to reduce the viscosity of the oil and increase the oil mobility. The main mechanism that contributes in the solvent-based enhanced oil recovery method is the mass transfer from the … Lire la suite

2014 — Low-Cost Grain Bin Moisture Sensor Using Multiple Capacitive ElementsRésumé
The ability to know the condition of grain stored on the farm is very important. Grains grown in the prairie provinces of Canada are valuable commodities and the farm has become a primary storage location for more and more grain as farming operations have been getting larger and larger. With increased storage, the risk of spoilage is ever present. Both spoilage and the cost of drying grain reduce profit. These factors have created a need for better on farm management of stored grain, and therefore a need for a reasonable cost sensor to continuously monitor the moisture inside the bins. … Lire la suite

2014 — Can a Single Bout of Aerobic Exercise Reduce Anxiety Sensitivity? A Randomized Controlled TrialRésumé
A growing body of research supports the benefits of exercise for a variety of mental disorders, including anxiety. Several mechanisms have been posited for the anxiolytic effects of exercise, including reductions in anxiety sensitivity (i.e., fear of arousalrelated sensations, based on the beliefs that these sensations may have harmful or negative consequences) through exposure to these feared bodily sensations. Studies on aerobic exercise lend support to this hypothesis; however, research comparing exercise to placebo controls and evidence for the dose-response relationship between exercise and reductions in anxiety sensitivity are lacking. The present trial was designed to investigate reductions in anxiety … Lire la suite

2014 — Bivariate Log Location-Scale Model For Interval-Censored DataRésumé
Censored data is very common in survival analyses and experimental observations. In this thesis, I consider a selected bivariate model concerning censored data. I rst review three basic univariate models, leading to corresponding bivariate models, in more complicated forms. Also I will discuss the properties of an actual, selected bi- variate model with interval-censored data. Then, I would like to derive the likelihood form for bivariate data, and give the maximum-likelihood estimation of the parame- ters. At last, the results of some simulation work, using R, will be showed to verify whether my estimation method is good. Lire la suite

2014 — Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,Résumé
In continuous CO2 secondary flooding, severe viscous fingering and early CO2 breakthrough (BT) occur due to an unfavourable mobility contrast between the injected CO2 and the crude oil. The oil recovery is limited after CO2 BT, which is attributed to the gas channeling problem. In continuous CO2 tertiary flooding, the previously injected water helps to control the mobility of the subsequently injected CO2. On the other hand, it hinders the mutual interactions between the residual oil and the subsequently injected CO2 and thus affects the tertiary oil recovery. This thesis experimentally studied the mutual interactions between the light oil/reservoir brine … Lire la suite

2014 — “A Personal Odyssey”: Contrapuntal Heroism in the Works of Diana Wynne JonesRésumé
This study examines one specific aspect of Diana Wynne Jones’ fantasy fiction— her use of multiple, interdependent character identities to craft heroes whose heroic journeys do not necessitate violence or conformity with preset definitions of heroism. These characters’ heroic journeys are inward ones of self-acceptance and empathy rather than outward ones that lead to external conflict. Because their identities are not always fragmented or divided, I use the term contrapuntal to describe them. Counterpoint, in classical music, refers to pieces crafted from two or more similar melodies interwoven together, and thus is a fitting concept to use in describing Jones’ … Lire la suite

2014 — Long-term Neuropsychological and Psychosocial Consequences of Pediatric Mild Traumatic Brain InjuryRésumé
Traumatic brain injury (TBI) is a major health problem affecting thousands of Canadians and their families each year. Little is known about the long-term consequences of pediatric mild traumatic brain injury (MTBI) on psychological functioning in adulthood. There are two major perspectives on this topic. The Kennard Principle asserts that young brains are more plastic and thus better suited to compensate following injury. The Early Vulnerability Hypothesis challenges this assertion with the idea that early damage to the brain may have significant implications for emerging cognitive and social skills. Executive function and social competence are skills that may be especially … Lire la suite

2014 — Retail Price Time Series ImputationRésumé
A regular, discrete time series is an ordered sequence of coarse-grained observations taken at fixed time intervals. Here we consider regular, discrete, retail price time series datasets acquired through crowdsourcing. Crowdsourcing is a means of data collection whereby independent individuals push publicly-available information to an information consolidator who then distributes it back to the individuals for their collective mutual benefit. Crowdsourced datasets are typically incomplete due to missing observations and missing values for important attributes. In this thesis, we consider the problem of filling in missing values in crowdsourced, regular, discrete, retail price time series datasets using data imputation methods. … Lire la suite

2014 — The Impact of a Cardiac Rehabilitation Program and Gender on Depressive Symptoms in Cardiac PatientsRésumé
A cardiac event affects the physical and psychological well being of individuals. Among the psychological consequences, researchers have found that a cardiac event can lead to high levels of depressive symptoms in both males and females (Milani, Lavie, & Cassidy, 1996). To date, research has confirmed the beneficial effects of a cardiac rehabilitation (CR) program on depressive symptoms (Casey, Hughes, Waechter, Josephson, & Rosneck, 2008; Zellweger, Osterwalder, Langewitz, & Pfisterer, 2004); however, there has been a limited focus on how males and females differ in their depressive symptoms both prior to commencing and after completing a CR program. Previous research … Lire la suite

2014 — Saskatchewan Town Hall Opera Houses and Community Performance (ca. 1883-1913)Résumé
The construction of public spaces is just one mechanism by which a community builds and continually negotiates the idea, or mythos, of its identity. Communities, through their dominant groups (including economic, social, political, and religious), seek to adopt a dominant narrative regarding common community ideals and aspirations. Communities in Canada’s “new” West of the late 19th and early 20th centuries provide good examples of such community building where the construction of public spaces went hand in hand with the negotiation of collective ideology and identity. In particular, Town Hall Opera Houses (constructed early in the development of numerous Saskatchewan towns) … Lire la suite

2014 — Battlefords Domestic Violence Treatment Option (BDVTO) Court: Examining the Standpoint of Female VictimsRésumé
Intimate partner violence (IPV) is a serious and complex social issue with potentially fatal consequences. Beginning in the 1990s, specialized domestic violence courts gained prevalence throughout several jurisdictions in Canada as a mechanism to address victims’ needs (i.e. safety, support, participation and empowerment) while, largely by the use of therapeutic jurisprudential tenets, increasing offender accountability. The Battlefords Domestic Violence Treatment Option (BDVTO) began holding bi-weekly docket court on April 10, 2003. This study presents the lived experiences of three female survivors who volunteered to share their standpoint, regarding their involvement with the BDVTO Court. Through the survivors’ detailed first-hand testimonies, … Lire la suite

2014 — Territorial Stigma on the Canadian Prairies: Representations of North Central, ReginaRésumé
The community of North Central, located within the small prairie city of Regina, Saskatchewan in Canada, is known for high crime rates, poor socioeconomic conditions and a large concentration of Aboriginal residents. The area’s negative reputation was furthered when MacLean’s magazine named it “Canada’s Worst Neighbourhood” in 2007. The goal of this research is to offer a richer context for this "reputation" by investigating North Central as a stigmatized territory. Territorial stigma has harmful effects (i.e. negatively impacts the social, economic, physical and mental wellbeing of residents) and as such, the role of representation and stigma must be analyzed so … Lire la suite

2014 — Experimental, Numerical, and Soft Computing-Based Analysis of the Vapex Process in Heavy Oil SystemsRésumé
There are significant heavy oil and bitumen resources in Canada. Considering increasing energy demands, these abundant resources are a potential energy source. Regardless, looking for an economically viable and environmentally friendly heavy oil recovery technique is essential for exploiting not just these resources, but all future heavy oil resources. The problems with highly viscous heavy oil reservoirs—excessive heat loss to the surrounding formations, low permeability carbonate reservoirs, and the large amount of CO2 emitted during these thermal processes—introduce economic and environmental drawbacks for thermal methods. In fact, solvent-based heavy oil recovery methods have recently gained attention due to the potential … Lire la suite

2014 — A Randomized Controlled Trial of a Therapist- Assisted Internet Cognitive Behaviour Therapy Program for Women with Postpartum DepressionRésumé
Postpartum depression (PPD) impacts up to 15% of Canadian women following childbirth. The debilitating disorder not only impacts the woman, but also is related to short- and long-term consequences of her infant‘s development. A systematic review of psychological treatments for PPD demonstrated symptomatic improvements from pre- to post-treatment and superiority to control conditions (Sockol, Epperson, & Barber, 2011). Remarkably, many women suffering from PPD do not receive appropriate treatment. Internet and computer-based delivery formats are an innovative way to improve access to psychological treatment. While therapist-assisted Internet cognitive behaviour therapy (TAICBT) has proven more efficacious than a controlled waitlist condition … Lire la suite

2014 — Variations on a Theorem of Erdös, Ko and RadoRésumé
The Erdös-Ko-Rado theorem, a theorem which gives the size and structure of the largest pairwise intersecting collection of k-subsets from a base set of size n, has inspired many variations on the theme of the maximum size and structure of intersecting families. Some results for intersecting set systems add additional conditions or vary the intersection requirement. For instance, Hajnal and Rothschild allow up to s mutually disjoint sets. Hilton and Milner consider the largest families that do not have an element common to all of the k-subsets. Another variation is to consider objects other than subsets. For each object, a … Lire la suite

2014 — Synthesis and Reactivity of Functionalized Electrophilic Phosphinidene ComplexesRésumé
Electrophilic phosphinidene complexes play an important role in organophosphorus synthesis. The chemistry of neutral phosphinidene complexes has been well studied, but cationic phosphinidene complexes are not as well understood. Therefore, new cationic phosphinidene complexes have been synthesized and their reactivity towards bond activation, cycloaddition and nucleophilic addition has been examined. The terminal chloroisopropyl phosphido complex [Cp*Mo(CO)3{P(Cl)i-Pr}] was synthesized, and abstraction of chloride from it generates the transient cationic alkylphosphinidene complex [Cp*Mo(CO)3{P(i-Pr)}]+, which can be trapped with diphenylacetylene to form a phosphirene complex. Trapping with P(C6H5)3 leads to a phosphine coordinated phosphinidene complex. Trapping with diphenylsilane leads to SiH activation and … Lire la suite

2014 — Every ‘Body’ Has A History: Embodied Values of Ballet TeachersRésumé
This dissertation is an inquiry into the meaning of the teacher’s body in the pedagogy of female dance teachers. It explores how teachers experience their bodies, and considers the values which become embodied and normalized through the style of dance recognized as classical ballet and the international training institution known as the Royal Academy of Dance (RAD). Framed by hermeneutic phenomenology, the research incorporates a poststructural genealogy and related concepts to situate experience as constituted historically, culturally, and institutionally. Feminist concerns inform, and arts-based ways of knowing infuse, both methodology and method. Participants were recruited through a purpose-driven sampling process. … Lire la suite
