Are Health Care Professionals Addressing The Psychological Aspect Of Athletic Injury? A Survey Of Injured Athletes, Hayley C. Russell

Theses and Dissertations (Comprehensive)

Millions of athletic injuries occur annually. Athletic injures involve not only physical distress but psychological distress as well. Nevertheless, injured athletes rarely see a mental health care professional. It has been suggested that health care professionals, such as physicians, physiotherapists, and athletic therapists, are well positioned to address the psychological aspect of injury. Health care professionals report that they sometimes address the psychological aspect of injury with the athletes they treat. There is limited research, however, on what injured athletes perceive to be the role of health care professionals in addressing the psychological aspect of injuries. Therefore the purpose of …

Moral Emotion Expectancies In Adolescence: A Cross-Cultural Perspective, Fanli Jia

Theses and Dissertations (Comprehensive)

Cross-cultural research on moral development has documented reliable cultural differences in people’s evaluations of moral and immoral actions. Prosocial actions are typically viewed as more obligatory and less discretionary in collectivistic cultures relative to individualistic cultures. While past research mostly focused on moral judgments, it largely neglected moral emotions. The present study was aimed at investigating self- and other-evaluative emotions following (im) moral actions in different situational and cultural contexts. It investigated moral emotion expectancies of Canadian and Chinese adolescents and young adults across different situational contexts. For each culture, 179 Canadian and 193 Chinese adolescents from grade levels 7-8, …

Attentional Biases In Social Anxiety: An Investigation Of Rumination, Katie L. Walters

Theses and Dissertations (Comprehensive)

Cognitive models of anxiety posit that socially anxious individuals’ attention is disproportionally biased for threatening information in the environment. One component in the cognitive model of social anxiety that has not been examined, in terms of the attentional bias, is rumination (i.e., the dwelling on perceived inadequacies). The purpose of the present research was to examine the impact that rumination had on attentional biases in social anxiety as measured through the use of a Rapid Serial Visual Presentation (RSVP) stream. When two target stimuli (T1 and T2) are presented amongst distractor stimuli in rapid succession it is hard to process …

Financial Securities Under Nonlinear Diffusion Asset Pricing Model, Andrey Vasilyev

Theses and Dissertations (Comprehensive)

In this thesis we investigate two pricing models for valuing financial derivatives. Both models are diffusion processes with a linear drift and nonlinear diffusion coefficient. The forward price process of these models is a martingale under an assumed risk-neutral measure and the transition probability densities are given in analytically closed form. Specifically, we study and calibrate two different families of models that are constructed based on a so-called diffusion canonical transformation. One family follows from the Ornstein-Uhlenbeck diffusion (the UOU family) and the other—from the Cox-Ingersoll-Ross process (the Confluent-U family).

The first part of the thesis considers single-asset and multi-asset …

Living On Breath And Spirit: Spiritual Intelligence And Spiritual Journey In The Christian Faith Tradition, Maria Zinsstag

Theses and Dissertations (Comprehensive)

In the last decade, one observes an increased interest in applied spirituality that takes into account the fact that spirituality has left the boundaries of religion. Psychologists and neuroscientists postulate a spiritual intelligence. As a scientific concept it adopts an etic perspective on spirituality. It is used in healthcare, management and education. It is interested in spirituality but not in religion. Christian spirituality on the other hand is rooted in a particular religion. Lytta Basset offers guidance for spiritual growth in the Christian faith tradition. Because spiritual growth is very personal, Basset adopts an emic perspective on spiritual experiences. This …

An Apple A Day: Exploring Food And Agricultural Knowledge And Skill Among Children In Southern Ontario, Shannon Alberta Kornelsen

Theses and Dissertations (Comprehensive)

While the literature on food has somewhat addressed rudimentary food skills and their importance in the creation and maintenance of a healthy population, there remains a serious lack of research into the importance of food and agricultural skills and knowledge transference to children, especially given the rise in diet-related illnesses. This study focuses on the perceived importance of food and agricultural education initiatives, as well as the opportunities and barriers that exist within the elementary school classroom to incorporate food and agricultural topics, in the context of southern Ontario, specifically Wellington County. Drawing on Wilkin's concept of ‘food citizenship’ as …

Isolation And Characterization Of Ligands For The Goldfish Testicular Androgen Receptor From Kraft Mill Chemical Recovery Condensates, Philip David Scott

Theses and Dissertations (Comprehensive)

An investigation of cause was started in the 1990s at a bleached Kraft mill (BKM), located in Saint John NB, Canada. The 5th effect chemical recovery condensates waste stream (derived from wastewater generated during the pulping process) was identified as having the greatest potential for affecting mummichog (Fundulus heteroclitus), compared to the rest of the inmill waste streams. A solid phase extraction (SPE) protocol was utilized to isolate the causative chemicals in the condensate stream. Goldfish testicular androgen receptors (ARs) were exposed to five extracts: filter paper non-polar/polar, solid phase extraction nonpolar/polar, and residual condensates. The filter paper …

Plant Isotopes As Indicators Of N Cycling Processes In Agricultural Fields, Eric Thuss

Theses and Dissertations (Comprehensive)

When nitrogen (N) availability exceeds biological demand, excess N, especially nitrate (NO₃), may subsequently pollute ground and surface water. Agricultural practices in Southern Ontario typically supplement soils with organic and inorganic nutrients to aid in crop development, and employ various management techniques to limit nutrient loss. Excess N has several potential fates, which are controlled by the net effects of numerous N cycling reactions in the soil that are often difficult to measure directly. N cycling in soils is controlled in large part by soil moisture, as it affects microbial activity and soil redox conditions. Stable isotope geochemistry …

Carbon Dioxide Exchange In A Permafrost-Dominated Boreal Wetland In The Northwest Territories, Canada, Andrea J. Kenward

Theses and Dissertations (Comprehensive)

Northern boreal wetland complexes are substantial reservoirs for carbon and play a crucial role in both regional and global carbon budgets but they are showing significant signs of impact by climate change. This study examined the carbon dioxide flux of a high boreal wetland during the snowmelt and growing season of 2008 in Scotty Creek Basin, located near Fort Simpson (61°18'N, 121°18'W), Northwest Territories. This basin is not only responding to shifts in atmospheric temperatures, but it is also under additional pressure from increasing permafrost degradation. A dynamic closed-system chamber was used to monitor and quantify mid-day total respiration (R …

Microporous Organic Polymers: Synthesis And Post Synthetic Modifications, Phillip Andrew Kerneghan

Theses and Dissertations (Comprehensive)

Microporous solids are an important class of materials that have been studied extensively. Newer to this field are Microporous Organic Polymers (MOPs) which are networks constructed from smaller organic building blocks and exhibit large surface areas, small pore sizes and low densities. It is due to these characteristics that MOPs have attracted attention because of their potential use in applications such as catalysis, chemical separations and gas storage.

In this thesis is described the synthesis of two novel MOPs, the first of which being a network based on benzenediboronic acid and triptycene building blocks linked together by boronate esters. This …

Investigating The Relationship Between Motor Resonance And Nonconscious Mimicry, Jeremy Hogeveen

Theses and Dissertations (Comprehensive)

Motor resonance refers to the mirroring of observed actions in one’s own motor system. It is possible that motor resonance is the neural mechanism underlying nonconscious mimicry (NCM)—the ubiquitous phenomenon wherein people mimic the behaviour of interaction partners (Chartrand & Bargh, 1999). Previous research has shown that priming interdependent selfconstrual (interSC) increases mimicry (van Baaren et al., 2003). If motor resonance is the mechanism underlying NCM, then a manipulation known to facilitate mimicry (i.e. interSC) should increase motor resonance. In experiment one, we variably primed independent selfconstrual (indSC)—known to inhibit mimicryv—and interSC in a motor priming paradigm. Participants observed videos …

Interviewing Children About Repeated Events: Does Mental Context Reinstatement Improve Young Children’S Narratives?, Donna M. Drohan-Jennings

Theses and Dissertations (Comprehensive)

This study examined mental context reinstatement (MCR) as a technique to increase the quantity and accuracy of information provided by children during repeated-event narratives. Children (N = 46, 4-, 5- and 6-year olds) participated in four repeated laboratory activities and were interviewed 4-7 days later about the last occurrence with a control or MCR interview, including both a free narrative and specific questions about the events. Older children (6-year olds) provided a greater number of accurate instantiations (specific details) compared to 4-year olds. Five and 6-year olds reported a greater number of instantiations than 4-year olds, but this effect …

Administration Of A Cannabinoid Receptor Antagonist Following Chronic ∆9-Tetrahydrocannabinol Induces Physical Withdrawal In The Absence Of A Dysphoric State, Brittany Ford

Theses and Dissertations (Comprehensive)

The selective cannabinoid CB1 receptor antagonist SR141716 has been shown to precipitate physical signs of withdrawal in ∆⁹-tetrahydrocannabinol (THC)-dependent rats; however, the affective state associated with this withdrawal state has not yet been well characterized. Thus, the aim of present study was to examine the physical and affective consequences of SR141716-precipitated THC withdrawal in male Sprague-Dawley rats. Rats were injected with THC (5 mg/kg, i.p.) or its vehicle twice daily for 13 consecutive days, and challenged with SRI 41716 (1 mg/kg, i.p.) or its vehicle 1 h later on days 3, 5, 7, 9, 11, and 13. Consistent …

Poverty And Disability: The Need For Inclusion, Alexis Buettgen

Theses and Dissertations (Comprehensive)

Despite the fact that people with disabilities are disproportionately represented among the world’s poorest, they have been marginalized in poverty research and have had minimal involvement in poverty reduction strategies. The current study addresses this issue, by providing an opportunity for people with developmental disabilities to control and direct the research agenda, and to have an active voice on the topic of poverty and disability. Thus, the present study aims to support the development of poverty reduction strategies by raising key issues and breaking down barriers to participation for people with developmental disabilities. This study utilized a social power framework …

Shape memory alloys (SMAs) belong to an interesting type of materials that have attracted the attention of scientists and engineers over the last few decades. They have some interesting properties that made them the subject of extensive research to find the best ways to utilize them in different engineering, biomedical, and scientific applications. In this thesis, we develop a mathematical model and analyze the behavior of SMAs by considering a one degree of freedom nonlinear oscillator consisting of a mass connected to a fixed frame through a viscous damping and a shape memory alloy device. Due to the nonlinear and …

Understanding Academic Success For Onkwehonwe (Indigenous) Students Through The Use Of An Onkwehonwe'neha (Indigenous Methodology), Ashley Victoria Dorothy Johnson

Theses and Dissertations (Comprehensive)

School-retention rates for Indigenous (Onkwehonwe) students are disproportionately lower than the non-Indigenous population in Canada (Mendelson, 2006). Currently, few studies on Native education acquire the perspectives and knowledge from successful OS. Many nonpersistence factors for OS have been uncovered, but few studies have offered solutions. Additionally, there is minimal (re)search using an Indigenous methodology (Onkwehonwe’neha) in the exploration Onkwehonwe education. This search (study) focused on the perspectives and experiences of six successful OS (i.e., five graduate students and one entering a graduate program). Two of the six participants were Aboriginal student-services coordinators at accredited universities within Ontario, Canada. Through the …

Evaluation Of The Use Of Healing Imagery In Athletic Injury Rehabilitation, Joel Cressman

Theses and Dissertations (Comprehensive)

Healing imagery can be defined as both visualizing affirmative images ofinternal physiological healing occurring in an injured area and visualizing oneselfas healthy and fully functioning (Driediger, Hall, & Callow, 2006). Healing imagery has been found to effectively reduce the time of recovery from various athletic injuries when used in combination with other mental skills, such as self-talk and relaxation (Ievleva & Orlick, 1991). However, the literature remains void of a study that specifically examines healing imagery and the potential benefits that may accompany the regular application ofhealing imagery techniques alone. This study examined the effects ofan imagery intervention on the …

Reconstructing Sex: Women Having Sex With Women, Alixandra Holtby

Theses and Dissertations (Comprehensive)

This study examines the experience of exclusion from the dominant understandings of sex for women who have sex with women, including queer, pansexual, bisexual, and lesbian women. Using ideas of the constructed nature of sex, particularly the use of sexual scripts (Simon & Gagnon, 1973), as well as the (hetero)sexist context in which these scripts are formed, qualitative interviews with 11 queer, pansexual, bisexual, and lesbian women were analyzed regarding their development of their understandings of what constitutes sex, their expectations and experiences of sex, their negotiation of desire and sexual identity, and their perspectives on sex between women and …

Effects Of Chlorpromazine On Feeding And Wheel Running On Rats With Acute Wheel Access, Graham Gregory Parfeniuk

Theses and Dissertations (Comprehensive)

Anorexia Nervosa (AN) is characterized by a self-imposed starvation and is often accompanied by excessive exercise that results in severe malnutrition and sometimes death. Behavioural and pharmacological treatments of AN need to be improved. In rats, acute 3 h daytime wheel access suppresses ad lib feeding over the subsequent night relative to no wheel controls, a phenomenon that has been suggested as an animal model of AN. This acute wheel induced feeding suppression (WIFS), can be induced reliably when rats are given limited wheel access exposure during the light cycle (Lattanzio & Eikelboom, 2003). The acute WIFS is useful because …

Two Sides To Every Trauma: The Role Of Posttraumatic Growth And Decline In Well-Being, Danay C. Novoa

Theses and Dissertations (Comprehensive)

Research clearly demonstrates how traumatic events can damage psychological and physical health (Janoff-Bulman, 1992). However, Tedeschi and Calhoun (2004) argue that posttraumatic growth can also occur following adversity. Although largely well-received, their theory and the posttraumatic growth inventory (PTGI) have been critiqued as well. For instance, Wortman (2004) argues that Tedeschi and Calhoun give insufficient consideration to the negative consequences of traumatic events. Concurring with Wortman, we contend that the PTGI, constructed to measure only growth, does not allow participants the opportunity to report decline in any domain. This scale design may artificially inflate the apparent occurrence of posttraumatic growth …

A Qualitative Examination Of Sport Transitions In First Year Collegiate Female Athletes, Carolyn Mcewen

Theses and Dissertations (Comprehensive)

First year student athletes transitioning from high school to university experience simultaneous transitions in athletics, academics, social lives, family structures, support systems, and peer sport groups. These changes in their personal, social and occupational lives, can impact them cognitively, emotionally and behaviourally (Taylor & Ogilvie, 1994). The purpose of this study was to qualitatively examine the multi-dimensional transition experience of first-year collegiate athletes transitioning to higher level sports. A sample of eleven female varsity hockey, basketball, or volleyball athletes participated in two semi-structured interviews at beginning of the season and midseason. The first series of interviews were conducted face-to-face, with …

Predicting Resilience In Young Adult Turning Point Stories: A Narrative Approach To Understanding Well-Being, Norah Love

Theses and Dissertations (Comprehensive)

One way to understand well-being is through the examination of narrative turning point stories, which are stories about an event or episode that represents an important change in one’s life. To better understand what contributes to the well-being of young adults, this study examined predictors in adolescence of dimensions of turning point stories in young adulthood. Standardized measures of youth’s prosocial behaviour, hyperactivity, selfesteem, family functioning and sense of community in Grade 9 were used to predict the following narrative dimensions of Grade 12 youths’ (n=96) turning point stories: affect transformation, specificity, ending resolution, personal growth, meaning-making and …

Paleolimnological Reconstruction Of Hydrologic Change In The Slave River And Great Slave Lake During The Past Millennium, Matthew Ennis

Theses and Dissertations (Comprehensive)

The Slave River Delta (SRD), NWT, represents a pivotal node in the upper Mackenzie Basin watershed and is a productive northern wetland landscape with a rich natural and cultural heritage. Concerns over environmental consequences of natural and anthropogenic-driven decline in river discharge as well as climate variability have prompted hydroecological sstudies to improve understanding of how this ecosystem functions over time and space. However, long-term natural hydrological variability of the Slave River system is not well documented and needs to be further developed. In order to provide a temperal context for understanding and evaluating the impacts of climate variability and …

Theses and Dissertations (Comprehensive)

The purpose of the current thesis was to investigate the influence of dopamine replacement on performance during bimanual coordination in individuals with Parkinson’s disease (PD) There has been conflicting research on the cause of movement impairments such as coordination deficits, slowed switching and upper limb freezing that occur during coordinated movements It is unclear whether decreased function of the dopaminergic system after withdrawal from dopamine replacement is responsible for these deficits Healthy age-matched control participants were compared to PD participants in two experiments to determine the movement impairments that occurred during three-dimensional wrist flexion-extension bimanual coordination as a result of …

A Time Series Analysis: Exploring The Link Between Human Activity And Blood Glucose Fluctuation, Eric A. Sadowski

Theses and Dissertations (Comprehensive)

In this thesis, time series models are developed to explore the correlates of blood glucose (BG) fluctuation of diabetic patients. In particular, it is investigated whether certain human activities and lifestyle events (e.g. food and medication consumption, physical activity, travel and social interaction) influence BG, and if so, how. A unique dataset is utilized consisting of 40 diabetic patients who participated in a 3-day study involving continuous monitoring of blood glucose (BG) at five minute intervals, combined with measures for sugar; carbohydrate; calorie and insulin intake; physical activity; distance from home; time spent traveling via public transit and private automobile; …

Insights Into Genome Functional Organisation Through The Analysis Of Interaction Networks, Andre Masella

Theses and Dissertations (Comprehensive)

Using computational techniques to identify orthology and operon structure, it is possible to find functional interactions between genes, which, together, define the genetic interactome. These large networks contain information about the relationships between phenotypes in organisms as genes responsible for related abilities are often co-regulated and reasserting of these genes can be detected in the operon structure. However, these networks are too large to analyse by hand In order to practically analyse the networks, a computational tool, gisql, was developed and, using this tool, the connectivity patterns in the genetic interactome can be analysed to understand high-level organisation of …

The Pleiotropic Mutant R50 (Sym16): A Link Between Cytokinin And Starch Metabolism May Explain Its Seed Phenotype, Chengli Long

Theses and Dissertations (Comprehensive)

Cytokinins are a class of adenine-based plant hormones that stimulate cell divisions and are therefore essential for organ growth and development. The role that cytokinin plays in nodulation and that of R50 (syml6) in particular is very complex. In this study, a cytokinin antagonist and a cytokinin oxidase (CKX) inhibitor were used as tools to study the effects of cytokinin perception or cytokinin degradation on nodulation in pea, the cytokinin transduction pathway, especially that induced by CRE1/AHK4, and CKX play a significant role in pea nodulation. Comparison of the full length sequences PsCKX2 cDNAs from Sparkle and R50 …
