Effects And Mechanisms Of Female Sex Hormone Influence On Skeletal Muscle Inflammation, Sobia Iqbal

Theses and Dissertations (Comprehensive)

Previous work from our laboratory has demonstrated that estrogen will attenuate leukocyte infiltration into skeletal muscle following eccentric exercise. However the mechanisms by which estrogen exerts its effects are still uncertain. In experiment one, we investigated the role of estrogen receptor (ER) influence on muscle leukocyte infiltration following eccentric exercise through administration of the ER antagonist ICI 182,780 following downhill running in ovariectomized female rats with (E+) or without (E-) estrogen supplementation. At 24 hours post-exercise, soleus and white vastus muscles were removed and immunostained for HIS48 (neutrophil) and EDI (macrophage) positive cells. The increase in number of fibres positive …

Non-Preferred Limb Performance Following Prolonged Training Periods: Performance And Retention Of Skills, Matthew Thomas Mayer

Theses and Dissertations (Comprehensive)

The purpose of the current study was to examine if a long-term training program could improve non-preferred limb performance on a battery of standard tasks (Annett Pegboard, Grooved Pegboard Place and Remove Phase) and non-standard tasks (Scroll Task and Line-crossing Task). Upon completion of the training sessions, two new tasks were introduced, Finger Tapping and Fitt’s Law Task, to examine if any performance improvements could be transferred. A second purpose of the study was to learn if a training program could increase the perceived comfort in using the non-preferred hand on the same testing tasks. Participants were assigned to a …

The Influence Of Exercise Intensity On Exercise Induced Diaphragm Fatigue In Female Subjects, Anthony Errol Aqui

Theses and Dissertations (Comprehensive)

Exercise induced arterial hypoxemia (EIAH), expiratory flow limitation (EFL) and exercise induced diaphragm fatigue (EIDF) are examples of how the pulmonary system limits endurance exercise. The differences in the female anatomy and hormone fluctuations have been reported to cause differences in the occurrence of EIAH and EFL in males and females. EIDF has been reported to occur in males, but to date no investigations have reported the occurrence of EIDF in females. Therefore the purpose of this study was to determine the occurrence of exercise induced diaphragm fatigue (EIDF) in females identified by significant reductions in transdiaphramatic pressure (P_{di …}

Effects Of Orthotic Intervention During Running Among Individuals With Functional Flatfoot, E. Anne Cunningham

Theses and Dissertations (Comprehensive)

Foot orthotics are commonly prescribed to runners with functional flatfoot (FFF) with the goal of restoring the medial arch of the foot. In addition, treadmills are typically used by both clinicians and researchers in order to measure the lower extremity kinematics associated with running. However the mechanism of orthotic intervention as well as the accuracy of treadmills in representing overground running remains controversial within the literature.

This thesis first compared the lower extremity kinematics between treadmill and overground running among individuals with a subtalar neutral foot type. The results indicated no significant differences with respect to rate of rearfoot angle, …

Evaluation Of The Effects Of Various Exercise Interventions On Parkinson’S Disease, Michael D. Sage

Theses and Dissertations (Comprehensive)

The overall purpose of the current thesis was to evaluate the influence of various exercise strategies on Parkinson’s disease (PD). While countless exercise interventions have been investigated by PD, results have been weak and inconclusive at best. As such, there are currently no scientifically-validated recommendations for an optimal exercise intervention. The four studies comprising this thesis have attempted to address the shortcomings of previous literature, namely, inconsistent use of outcome measures, lack of PD symptomatic measures, varying lengths of exercise interventions, absence of a non-exercise control group, continued assessment of participants after exercise has ended, and verifying replicabilty of findings. …

Theses and Dissertations (Comprehensive)

The purpose of this research project was to qualitatively explore the experiences of live-out assistants in two L’Arche communities in order to better understand what these staff members perceived to be the benefits and challenges of community life in L’Arche. Live-out assistants support individuals with developmental disabilities in L’Arche communities, but do not live in a L’Arche home. This study incorporates theories related to the role of core values in uniting intentional communities and organizational change. Intentional communities face an ongoing challenge of adapting to internal and external changes, while retaining core values and a common purpose. An empowerment approach …

Evaluating Community Participation In Health Care Decision-Making: The Case Of The Airdie/North Rocky View Health Needs Project, Aleisha Dawn Harrington

Theses and Dissertations (Comprehensive)

Rising health care costs combined with limited health resources have made it essential for health agencies around the world to identify successful and affordable ways to prevent disease and promote health. Several national and international documents have proposed that increased community participation in health matters is one potential approach. While many of these reports detail the benefits of and need for community participation in health care decision-making, they provide little information as to how this should be achieved. The result has been a myriad of interpretations, interventions and practices of community participation. According to several scholars, evaluations are needed that …

Preaching As Spirit-Directed Witness, Klaus Sonnenberg

Theses and Dissertations (Comprehensive)

This study seeks to address two specific areas that have been comparatively neglected in modern homiletical writings. Firstly, there has been a reticence to view preaching as witness—which has resulted in what one perceptive homiletician has called “a testimonial vacuum” in much of the preaching that is done in the mainstream churches of the west; and secondly, there has been a scarcity of emphasis on the role of the Holy Spirit in theological writing, including in the crucial area of preaching. Happily, this is beginning to change: there is more and more material being written now in the area of …

Personal Stories Of Empathy In Adolescence And Emerging Adulthood, Kendall M. Soucie

Theses and Dissertations (Comprehensive)

Empathy, the ability to understand and experience the emotions of others, has yet to be investigated from a narrative or life story perspective. The purpose of the present study was, therefore, to examine the ways in which emerging adults and adolescents, through their self-defining stories, process and come to extract meaning from their personal empathic and non-empathic experiences. Twenty-nine adolescents (14–17, M=15.28, SD=.99), and 31 emerging adults (18–20, M=18.23, SD=.56) narrated stories about their empathic (times when they felt sad for someone, times when they put themselves in someone else’s shoes) and non-empathic experiences (times when …

In Search Of The Political Economy Of Oppression And Liberation: Towards Structural Validity For Community Psychology, Sune Sandbeck

Theses and Dissertations (Comprehensive)

Advocating for liberation from oppression through critical research and praxis has become a central concern among community psychologists. In this dissertation, I argue that while community psychology (CP) has had some success in integrating multidisciplinary knowledge, its understanding of oppression and liberation continues to be characterized by an avoidance of economic considerations. I posit the concept of structural validity as being necessary to re-focus our research and praxis on the economic structure of oppression. Within the current global context of systemic inequality, this economic structure is being ideologically driven by the doctrine and discourse of neoliberalism, which has important implications …

Impact Of Diagnostic Labels, Janice E. Dinsmore Czechowsky

Theses and Dissertations (Comprehensive)

To determine whether there was a difference between a physical or mental health diagnosis on well-being, identity, relationship with God, and ability to use faith as a source of support, quantitative and qualitative studies were conducted using surveys and three focus groups. Of the 360 surveys returned 54% failed to indicate whether they experienced a physical or mental health issue, resulting in the quantitative data being unusable. Focus group participants reported feeling safe during the group to disclose their health issue, but not prior, resulting from previous experiences with stigma. Mental health diagnoses still carry stigma. Participants reported a strong …

List Composition Effects For Masked Semantic Primes: Evidence Inconsistent With Activation Accounts, Jennifer C. Major

Theses and Dissertations (Comprehensive)

Priming is the benefit that an event receives when its processing has been preceded by the processing of a related or identical event. Context effects on priming are evident when priming changes as a function of some feature of experimental trials. The most commonly explored context effect is that of relatedness proportion (RP), where it has often been shown that the magnitude of priming (semantic or repetition) is directly related to the proportion of related trials: Increasing the related trials results in greater priming. Although previously thought to depend on strategic processing, recent evidence of context effects from designs using …

Origin Of Intentionality, Darryl J. Murphy

Theses and Dissertations (Comprehensive)

The modern origins of intentionality reside in the early work of Franz Brentano—specifically, his Psychology from an Empirical Standpoint (1876) and the notion of the “intentional inexistence” of the object of consciousness presented therein. “Intentional inexistence”, says Brentano, is the fundamental distinguishing characteristic of the objects that occupy our desires, aversions, thoughts, and all of our conscious activities in general. According to Brentano, “Aristotle himself spoke of this mental inexistence. In his book on the soul he says that the sensed object, as such, is in the sensing subject; that the sense contains the sensed object without its matter; that …

This case study explores the qualitative experience of 4 consumers with a dual disability living in a home specializing in dementia support. Drawing insights from participant observation, daily living log notes, and interviews with 4 each of family/friend caregivers, direct-care staff, and administrators, the study has 3 main goals: (i) to understand how the onset of dementia in people with an intellectual disability changes their needs, what adjustments have to be made in the support practices, and what service barriers and successes are experienced; (ii) to understand how people with dual disabilities experience living in a home specializing in dementia …

Intra-Urban Analysis Of Commercial Locations: A Gis-Based Approach, Christopher D. Storie

Theses and Dissertations (Comprehensive)

The urban landscape is an interspersed mixing of residences, shops, theaters, parks, natural areas, and a multitude of other uses. From the early days of the central markets, to the planned downtown, to the heavily planned super-regional shopping complexes, commercial landscapes evolve. There has been considerable research conducted on analyzing the commercial structure of urban environments in an attempt to better understanding the nature of retailing and its resultant impacts on the geography of the city.

This research has three broad goals: a) to develop a technique that makes operational, in a systematized and objective manner, an approach to analyzing …

The Story Of South African Child Welfare: A History Of The Present, Jeanette Elizabeth Schmid

Theses and Dissertations (Comprehensive)

Though significant transformation has occurred in post-apartheid South Africa, extensive poverty, AIDS and violence present major challenges. The capacity of families and local networks, undermined by apartheid policies, continue to be depleted, leaving children vulnerable. During the apartheid era, the child welfare sector, despite its intention of supporting children and families, utilized interventions that failed to address the needs of the majority and weakened family life. Post-apartheid, government has presented Developmental Social Welfare—with its family-centered, rights-oriented, community-based, participatory, generalist and intersectoral approach—as an indigenous correction to the previous expert-driven, pathologizing, individualistic, discriminatory and costly approaches.

Social Behavior Inventory: To Ipsatize Or Not To Ipsatize, That Is The Question, Carolyn Hoessler

Theses and Dissertations (Comprehensive)

This research extends prior knowledge of the statistical procedure of ipsatization, commonly utilized in interpersonal research to align data with theoretical expectations. The working hypotheses in prior studies have posited that a general factor, representing a response bias with no relevant substantive meaning, alters the data and interferes with analysis and interpretation unless removed by ipsatization. In the first of two studies, we initially investigated whether ipsatization removes important conceptual information from data when it removes a general factor. Three potential meanings of the general factor expected to occur in the Likert-scale version of the Social Behavior Inventory (SBI; Moskowitz, …

Asset-Based Community Development: A Case Study, Suzanne Killing Wood

Theses and Dissertations (Comprehensive)

This case describes an effort toward asset-based community development with an ‘underprivileged’ neighbourhood, including the responsive steps taken to deal with the realities and challenges of community change efforts. Through participant observation and in-depth interviews with key stakeholders, including residents and external supports, this paper examines changes in community activity in association with their newly formed community centre. Through analysis of the community’s challenges four ‘enabling conditions’ necessary for community development are identified including: balancing relationships with issues; effective ‘citizen space’; maintenance of relationships and communication; and community readiness. These key lessons include ongoing considerations of patience, flexibility, and responsiveness …

Self-Reported Acceptance Of Social Anxiety Sypmtoms: Development And Validation Of The Social Anxiety-Acceptance And Action Questionnaire, Meagan B. Mackenzie

Theses and Dissertations (Comprehensive)

Mindfulness-based interventions have been used in the treatment of social anxiety with initial success. Mindfulness is defined as an awareness and acceptance of the present moment. Acceptance when used as a coping strategy is related to reduced distress during anxiety-provoking tasks and increased willingness to experience unpleasant events. The purpose of this research was to examine acceptance, willingness and distress in the context of social anxiety and was threefold. The first study was designed to develop an instrument designed to assess acceptance specific to social anxiety. In Study 1, a sample of 352 undergraduates completed the initial 56-item pool of …

The Application Of Environmental Impact Assessment Legislation To The 2010 Winter Olympic Games Venue And Infastructure Development, Daniel Melbourne Patterson Kellar

Theses and Dissertations (Comprehensive)

Environmental impact assessment (EIA) is a tool which aims to make developments better by identifying, avoiding, and mitigating potential negative environmental impacts of projects and other action. With the 2010 Winter Olympic Games being held in the Vancouver to Whistler (sea-to-sky) corridor many developments have been initiated and EIA has played a role in 2010 site construction. Using case study analysis, legislative and literature reviews as well as open-ended interviews with key participants, stakeholders, and partners in the environmental impact assessment process, this study investigated the application of Canada’s and British Columbia’s environmental impact assessment legislations to the 2010 Olympic …

Trips Down Memory Lane: Recall Direction Affects The Subjective Distance Of Past Events, Kent C.H. Lam

Theses and Dissertations (Comprehensive)

The subjective temporal distance of a past event—how close or far away it feels—is influenced by numerous factors apart from actual time. The present studies extend research on subjective distance by exploring the experience of remembering autobiographical events as part of a stream of related events. It is proposed that a key determinant of subjective distance is the temporal direction in which events are recalled. Five experiments supported the hypothesis that people feel closer to a target event when they recall a stream of related events in a backward direction (i.e., a reverse-chronological order ending with the target event) rather …

Mis-Education And The Crisis In Male Subjectivity: William Godwin’S Middle Novels, 1799–1817, Lisa-Marie Lynn Butler

Theses and Dissertations (Comprehensive)

In the tumultuous period of the 1790s, the English anarchist philosopher William Godwin was a seminal figure whose 1793 Enquiry Concerning Political Justice and Its Influence on Morals and Happiness stood as a touchstone for the reform movement in Britain. Godwin is primarily known today as the author of Political Justice and Things As They Are; Or, The Adventures of Caleb Williams, a 1794 novel which many readers, past and present, have regarded as a fictionalized allegory of the philosophical claims outlined in Political Justice.

Although his fame as a novelist largely rests on this one popular novel, …

Perspectives On The Post-Degree Supervision Needs Of Ontario Social Workers, Heather Jane Hair

Theses and Dissertations (Comprehensive)

The dominant contemporary post-degree supervision literature reflects a long held belief that social workers employed in various practice settings need a combination of further education, support, and administrative guidance from someone more expert than themselves. In spite of these claims, a noticeable gap in knowledge is learning what, if anything, social workers need from supervision to help them provide effective services.

My particular interest is post-degree supervision within the social work landscape of Canada. I chose to focus this research project on the supervision needs of social workers in Ontario, the province where I have spent many years working as …

The Effects Of A Transition To University Intervention Program On Adjustment And Identity Development, Thanh-Thanh Tieu

Theses and Dissertations (Comprehensive)

The transition to university can be a stressful time for many students, whether it is smooth and successful, or full of difficulty. While the transition to university can be taxing enough, it also coincides with the period in which adolescents are said to be developing their sense of identity (Erikson, 1968). Given the stress many students experience, the Transition to University (T2U) Program, a social support focused intervention, was developed to assist students with the adjustment (e.g., Lamothe et al., 1995; Pratt et al., 2000). The purpose of this research was to examine the effects of the T2U Program on …

Hydrological Response Patterns And Solute Flux In Canadian Shield Basins: Role Of Different Physical Features And Antecedent Moisture Conditions, Jessica Mueller

Theses and Dissertations (Comprehensive)

Patterns of stream flow in relatively undisturbed Canadian Shield basins are closely linked to their physical and vegetative characteristics and meteorological conditions. The physical characteristics include topography, soil-till composition, depth and structure, slope morphology and bedrock geology. Hydrological flowpaths through, and in-situ chemical processes in the soil-till matrix are influenced greatly by the composition of these features and by the antecedent hydrological conditions preceding a given storm or snowmelt event.

A long term data set, collected by the Dorset Environmental Science Centre, is used to examine eight forested basins within the Muskoka-Haliburton region of south-central Ontario. The basins have a …
