The Relationship Between Socioeconomic Status And Physical Activity Among Adolescents, Meredith Laurel Stockie

Theses and Dissertations (Comprehensive)

Background: Many Canadian youth are inactive (Active Healthy Kids Canada, 2009). Socioeconomic status (SES) is one factor that influences youth physical activity (PA) levels; however, the factors involved in this relationship are not well understood. Given that numerous quantitative studies suggest there is a positive relationship between SES and PA among adolescents, but offer little insight into why the given relationship exists, the purpose of the current thesis is to study the factors that influence the relationship between SES and PA among youth aged 12–14 years through a qualitative lens.

Methods: Low (n = 2) and high SES (n = …

Using Scripture In Counselling Evangelicals, A. Tim Span

Theses and Dissertations (Comprehensive)

This thesis examines how the Bible can be used beneficially and ethically as a resource in counseling evangelicals. For evangelicals the Bible is their “primary text”—an unequalled source of authority and comfort. Evangelicals begin with the self-attestation of scripture to its own reliability and usefulness (e.g. 2 Tim. 3:16–17). When the scriptures are used in a responsible way using sound exegetical method there can be real dividends for the hearer. With proper preparation and informed consent, the counselor who ministers to evangelical clients can appropriate the message of the scriptures in a way that brings emotional and spiritual health. The …

The Influence Of Propyl Pyrazole Triol On The Post-Exercise Alpha Estrogen Receptor-Mediated Activation Of Satellite Cells In Skeletal Muscle Of Ovariectomized Rats, Amy Elisabeth Thomas

Theses and Dissertations (Comprehensive)

Estrogen has been shown to augment satellite cell activation, proliferation and total number and that this may occur through an estrogen receptor (ER) mediated mechanism. The purpose of this study was to investigate the role of ERs in the postexercise estrogen-induced augmentation of satellite cells in skeletal muscle of ovariectomized rats. Furthermore, the specific role of the ERα was examined through the use of an ERa agonist, propyl pyrazole triol (PPT). Ovariectomized rats were used (n=64) and separated into 4 groups: sham, estrogen supplemented, agonist supplemented and a combined estrogen and agonist supplemented group. These groups were further subdivided into …

Theses and Dissertations (Comprehensive)

The current study was designed to examine the experiences of organizations assisting individuals who are economically vulnerable in Waterloo Region through interorganizational collaboration. Several questions were explored in order to gain a deeper understanding of the definition of collaboration, for whom collaboration is useful, how often and with whom organizations collaborate, techniques used during collaboration, and whether collaboration should be increased and improved. Twenty Executive Directors from organizations most strongly involved in the assistance of those experiencing poverty were asked to participate in face-to-face interviews where they were asked questions based on the above mentioned questions. Qualitative analysis of the …

Models For On-Line Social Networks, Noor Hadi

Theses and Dissertations (Comprehensive)

On-line social networks such as Facebook or Myspace are of increasing interest to computer scientists, mathematicians, and social scientists alike. In such real-world networks, nodes represent people and edges represent friendships between them. Mathematical models have been proposed for a variety of complex real-world networks such as the web graph, but relatively few models exist for on-line social networks.

We present two new models for on-line social networks: a deterministic model we call Iterated Local Transitivity (ILT), and a random ILT model. We study various properties in the deterministic ILT model such as average degree, average distance, and diameter. We …

The Effect On Response Complexity On Task-Switching Behaviour, Christina Shepherd

Theses and Dissertations (Comprehensive)

Research on task-switching has shown that when participants are asked to switch between two different tasks, they are slower than when they repeat the same task. These costs have also been shown to increase when the previous response is repeated; however, very little has been done to investigate the role of response complexity in this relationship. We manipulated response complexity by increasing both the number of stimulus-response pairs and the number of individual response components. We hypothesized that increased response complexity would increase both the switch costs and the response repetition effect. Results indicated that increasing the number of S-R …

Inference, Orthology, And Inundation: Addressing Current Challenges In The Field Of Metagenomics, Gregory Detlev Alexander Vey

Theses and Dissertations (Comprehensive)

The vast increase in the number of sequenced genomes has irreversibly changed the landscape of the biological sciences and has spawned the current post-genomic era of research. Genomic data have illuminated many adaptation and survival strategies between species and their habitats. Moreover, the analysis of prokaryotic genomic sequences is indispensible for understanding the mechanisms of bacterial pathogens and for subsequently developing effective diagnostics, drugs, and vaccines. Computational strategies for the annotation of genomic sequences are driven by the inference of function from reference genomes. However, the effectiveness of such methods is bounded by the fractional diversity of known genomes. Although …

Responding To Change In A Northern Aboriginal Community (Fort Resolution, Nwt, Canada): Linking Social And Ecological Perspectives, Sonia Darienne Wesche

Theses and Dissertations (Comprehensive)

Human and environmental systems in the circumpolar north are particularly affected by the Earth’s changing climate, thus acting as a bellwether for other parts of the globe. Rural indigenous communities are most visibly impacted due to their close relationship with the land. These challenges are compounded by socio-economic transformations typical of peripheral communities within a larger, centrally governed system.

This dissertation links a community-based study of environmental change in Fort Resolution, Northwest Territories, Canada to evolving adaptation science. The study was prompted by local concern about changing environmental conditions caused by climatic, hydrological and resource development drivers. Its collaborative research …

A Systems Theory Examination Of Factors Related To Inclusive Attitudes Towards Newcomers And Racial Minorities, Shannon A. Veurink

Theses and Dissertations (Comprehensive)

The purpose of this study was to examine the relationship between certain social aspects of education and community experiences and how they relate to inclusive attitudes towards ethnic and racial minorities. A self-report, internet hosted survey was administered (N=672) in order to assess participants’ Attitudese Towards Immigration and Tolerance, as well as their educational and community-based experiences. Correlation and regression testing was completed to examine the relationships between education and community system experiences and inclusiveness. The findings of this study support the notio that experiences occurring within various social systems relate differently with inclusive attitudes. Implications and future research directions …

Event Syntax And Event Semantics As Constraints On Availability Of Discourse, Raymond B. Becker

Theses and Dissertations (Comprehensive)

The understanding of how temporal information constrains situation models is far from complete. In tehse two experiments participants read short stories, where the antecedent sentence was manipulated with respect to varying tense, grammatical and lexical verb aspect (Experiment 1), and then by varying grammatical and lexical verb aspect in conjunction with long and short duration events (Experiment 2). We used electrophysiological measures time-locked to the anaphoric referent to investigate how the brain responds to these temporal constraints. The purpose was to investigate teh possibility that these variables have an influence on the availability of discourse concepts in situation models. In …

Moral Emotion Expectancies And Moral Behavior In Adolescence, Megan E. Johnston

Theses and Dissertations (Comprehensive)

In the present research we extended previous studies examining moral emotion expectancies in childhood to investigate the relationship between moral emotion expectancies and moral behavior in adolescence. A secondary goal was to explore the relationships among moral emotion expectancies, the moral self, and moral action. Two hundred and thirty-five adolescents in grades 7, 9, 11, and first year university completed a structured interview assessing moral emotion expectancies in various situations in which a moral norm is either regarded or disregarded. Participants distributed up to 10 plastic chips on nine emotional expressions to indicate how they expected to feel in each …

Strict-Dominance Solvability Of Games On Continuous Strategy Spaces, Andrew Campbell Elkington

Theses and Dissertations (Comprehensive)

The concept of strict dominance provides a technique that can be used normatively to predict the play of games based only on the assumption of individual rationality. Such predictions, unlike those based on Nash equilibria, do not depend on players’ beliefs about the behaviour of others. One strategy strictly dominates another if and only if the payoff from the first strategy is strictly greater than the payoff from the second, no matter how the opponent(s) plays. It is possible for iterated elimination of strictly dominated strategies to remove all but a single choice for each player, in which case we …

Internal And External Triggers For Action, Shannon Matkovich

Theses and Dissertations (Comprehensive)

When the self paced preparation of an action is interrupted by a stimulus prompting the same motor response there is an increase in the reaction time to the stimulus as compared to an external or simple reaction time (SRT) condition (Obhi & Haggard, 2004). Previous studies have suggested that this cost is not attributable to perceptual or attentional factors. Therefore, to investigate the source of this RT cost we varied the motor demands of movements in Experiments one and two. Results indicated that the level of motor programming demands did not influence the RT cost in these experiments. While RTs …

Simulation Studies On Estimation Of Variance Components For Multilevel Models, Sara Vakilian

Theses and Dissertations (Comprehensive)

With the presence of unequal sampling in a multilevel model, the weight inflated estimators for variance components can be biased even though the use of survey weights results in design consistent estimators of the parameters. In this thesis I will carry out a simulation study to examine the performance of current existing methods and I will examine the resampling method for correcting bias of estimators of variance components of a multilevel model with covariates. This study will be based on these three papers: “Weighting for Unequal Selection Probabilities in Multilevel Models” by D. Pfeffermann , C. J. Skinner, D.J. Holmes, …

Understanding Best Practices For Community Engagement In Municipal Contexts, Sherry Mcgee

Theses and Dissertations (Comprehensive)

Engaging citizens in decision making has long been understood as part of the democratic process, most commonly recognized as electoral votership. In recent decades, the benefits of providing citizens a variety of opportunities for community engagement (CE) have been documented. Currently, few studies have explored the role of municipal government in engagement processes, and how engagement should be contextualized within municipal policy structures and practices. The City of Kitchener, located in Ontario, Canada is in the process of formalizing engagement practices through policy. In partnering with the City of Kitchener, five interviews were conducted with four Canadian municipalities and one …

Characterization Of The Interaction Between Arabidopsis Toc159 And Toc33 Gtpase Domains, Wesley A. Farquharson

Theses and Dissertations (Comprehensive)

Protein-protein interactions are critical for many biochemical processes and for cellular function. Understanding interactions between proteins and ligands, as well as other proteins are necessary for the modelling of biological systems. Protein import into chloroplasts is one such system where the understanding of interactions between members of the translocation complex is limited. The translocon at the outer envelope membrane of chloroplasts (Toe complex) consists of three core components: Toc75, Tocl59, and Toc34. Members of the Tocl59 and Toc34 gene families in Arabidopsis thaliana have been shown to assemble differentially into structurally and functionally distinct complexes. More specifically, there is evidence …

Consciousness From A Naturalistic Perspective, Hugh R. Alcock

Theses and Dissertations (Comprehensive)

Despite advances in neuroscience some sceptics, e.g., David Chalmers, Colin McGinn and Thomas Nagel, contend that we are no nearer to achieving a scientific understanding of phenomenal consciousness. These sceptics claim that naturalising consciousness, i.e., subsuming it under our scientific theories, is either impossible, at least without radically reforming our current scientific practices, or perhaps beyond our cognitive grasp. Their scepticism is based on what is called the ‘problem of consciousness’ or the ‘hard problem’. I argue that their pessimism is unwarranted. Their conclusion is based on adopting a nonnaturalistic attitude, according to which our scientific theories must accommodate our …

Knowing Body, Moving Mind: Ritualizing And Learning In Two Buddhist Centres In Toronto, Patricia Q. Campbell

Theses and Dissertations (Comprehensive)

This book explores learning through ritualizing in introductory meditation courses offered at two Tibetan-based, western Buddhist centres in Toronto. Through interviews with several of the centres’ newcomers, experienced members and teachers, it explores students’ reasons for enrolling in meditation classes as well as their attitudes towards religion and ritual. The study's primary focus is on respondents’ experiences of learning through formal practices such as meditation postures and techniques. Ritualizing is interpreted in part through performance theory, an approach which highlights the performative elements of ritual and the physical enactment of ritualized postures and gestures. Learning through ritualized activities creates a …

Globalization Mitigated: Human Rights, Corporations, And The New World Economy, M. Raymond Izarali

Theses and Dissertations (Comprehensive)

In this thesis, I argue for a set of basic human rights to constrain the practices of corporate entities in the context of economic globalization. These basic rights are derived through a concrete interpretation of specific articles in the Universal Declaration of Human Rights. My focus is on constructing a middle-ground approach to economic globalization by building on the work of Peter Singer, Onara O’Neill, John Bishop, and Leo Groarke, but with particular emphasis on Groarke’s notion of a mitigated capitalism. The underlying objective of the middle ground is to secure globalization’s benefits and circumvent its harms. As I am …

Computer Integration In Elementary And Secondary Schools: Variables Influencing Educators, Julie Mueller

Theses and Dissertations (Comprehensive)

Given the prevalence of computers in education today, it is critical to understand teachers’ perspectives regarding computer integration in their classrooms. Research identifying stages of implementation, and literature identifying barriers and supports, fall short of explaining what variables impact an educator’s ultimate decision to integrate technology in their instruction. The current research surveyed a heterogeneous sample of 185 elementary and 204 secondary teachers in order to provide a comprehensive summary of teacher characteristics and variables that discriminate teachers who integrate technology from those who do not. Discriminant Function Analysis (DFA) identified the following variables as making unique contributions to discriminating …

Neural And Behavioural Effects Of The Ginkgo Biloba Leaf Extract Egb 761, Elham Satvat

Theses and Dissertations (Comprehensive)

Numerous studies have documented the cognitive-enhancing effects of standardized Ginkgo biloba leaf extracts (Ginkgo) both in humans and in rodents. In addition to its antioxidant and platelet-activating factor inhibiting properties, Gingko has been shown to protect cellular membrane fluidity, to enhance cerebral blood flow and microcirculation, and to modulate cholinergic system functioning, properties that have been suggested to underlie its cognitive-enhancing effects. However, the possible neurogenic-enhancing effects of Ginkgo on adult hippocampal neurogenesis as a possible mechanism underlying its nootropic effects have not been evaluated. The experiments discussed in the present thesis assessed such a possibility.

Chapter 1 …

The Paradox Of Exclusion Within Equity: Interrogating Discourse At The Canadian Human Rights Tribunal, Delores V. Mullings

Theses and Dissertations (Comprehensive)

Employment discrimination has been a challenge in Canada for many groups and for government agencies who propose to adhere to a human rights agenda. To address this concern, the federal government initiated various anti-discriminatory policies and programs to counteract employment discrimination for four designated groups: Aboriginal people, “visible minorities,” women, and people with disabilities. The Employment Equity Act and the Canadian Human Rights Act were the legislation, and the Canadian Human Rights Commission and the Canadian Human Rights Tribunal the institutions designed to deal with employment discrimination for federal employees. When employees file a claim, it is initially processed at …

The Rules Of Engagement: German Women And British Occupiers, 1945–1949, Barbara Smith

Theses and Dissertations (Comprehensive)

This dissertation is a document based administrative study of the British occupation of Germany, 1945–49, and its impact on specific areas of the lives of German women who were living in the British zone. The study examines the effect of British occupation policy on the regulation of marriage, prostitution and venereal disease, and German women’s organizations. British occupation strategies were unique; although the British worked with the Americans on many levels they maintained separate policy approaches. The British brought their own social perspectives and systems to Germany and attempted to impose them on German social and civil procedures. German women …

Evaluating The Effectiveness Of A Short-Duration Reading Intervention On Grade One Phonological Awareness And Word Reading, Carrie Seward

Theses and Dissertations (Comprehensive)

The purpose of this project was to evaluate the influence of a summer intervention for children showing early signs of reading delay. The project evaluated two intervention components: a two week camp for children and two training workshops for parents. Data were collected for five groups of participants. Three groups participated in one or more intervention components: parent workshops only group, child camp only group, and both parent workshops and child camp group. All children who participated in the interventions were identified by teachers as having difficulty in phonological awareness and word reading skills at the end of senior kindergarten. …

Saltwater Sacraments And Backwoods Sins: Contemporary Atlantic Canadian Literature And The Rise Of Literary Catholicism, Andrew Peter Atkinson

Theses and Dissertations (Comprehensive)

In the 1990s, Canadian readers were offered a new literary trend: the Atlantic Canadian Catholic novel. In this dissertation, I examine works from six authors whose writing reflects the scope of this trend and I argue for a consideration of their collective impact on our social imaginary. The bulk of my argument is devoted to an examination of the Catholic religious content in the five novels and one memoir: David Adams Richards’ Bay of Love and Sorrows (1998); Ann-Marie MacDonald’s Fall on Your Knees (1996); Lynn Coady’s Strange Heaven (1996); Wayne Johnston’s Baltimore’s Mansion: A Memoir (1999); Patrick Kavanagh’s Gaff …

Phantoms Of Old Forms: The Gothic Mode In The Dramatic Verse Of Tennyson And Browning, Michael E. Ackerman

Theses and Dissertations (Comprehensive)

My dissertation, “Phantoms of Old Forms: The Gothic Mode in the Dramatic Verse of Tennyson and Browning” situates Alfred Lord Tennyson and Robert Browning within a lineage of writers who experimented with the Gothic mode in dramatic and verse forms. This study is, in the first instance, an experiment in applying a specific strain of Gothic critical theory, one that addresses issues of gender, to canonical literary materials not ordinarily approached in that light. Definitions of the Gothic are notoriously elusive, and this project is not an assertion that the Gothic is always, in all of its manifestations, about gender. …

Acknowledging The Skeletons In Our Closet: Collective Guilt And Ingroup-Affirmation, Gregory Roy Gunn

Theses and Dissertations (Comprehensive)

Just as people defend against threats to personal identity, they also defend against threats to social identity. In the context of intergroup transgression, the defensiveness against social identity threat has the effect of undermining collective guilt and its prosocial consequences. However, there may be ways for perpetrator groups to alleviate threat without undermining guilt. Five studies examined whether perpetrator groups are more willing to acknowledge collective guilt once social identity threat has been buffered by ingroup-affirmation. As predicted, Study 1 revealed that men accepted greater collective guilt for the mistreatment of women after affirming their ingroup. Replicating this effect, Study …

Keeping Kids Safe In Custody: Youths’ Perception Of Safety While Incarcerated In Canada, Judy Finlay

Theses and Dissertations (Comprehensive)

Keeping Kids Safe (KKS) is a study that presents an integrated model to demonstrate that the interaction between the predisposition of the youth and the institutional environment acts to promote or deter safety among incarcerated youth. The study illustrates that the peer subculture that produces a spectrum of violence within the institution is dependent on both the extra-custody attributes of the youth that affect his attitudes, beliefs and behaviours and on the critical influence of institutional attributes like program resources, staff/youth interactions and practices of social control. A predisposition that includes child maltreatment and exposure to domestic violence was used …

Commanding The Green Centre Line In Normandy: A Case Study Of Division Command In The Second World War, Angelo N. Caravaggio

Theses and Dissertations (Comprehensive)

This thesis examines the experiences of the 4th Canadian Armoured Division as it prepared for and carried out its role in the battle of Normandy and the libeation of France in 1944. The factors that limmited opportunities to practice the formation in large-scale exercises are noted as are the methods used by the General Officer Commanding, Major-General George Kitching, to compensate for the limitations. This thesis argues that through the development of an effective commander-staff dynamic Kitching, his staff and his subordinates commanders, were able to meet the challenges and chaos of combat in the final stages of the Normandy …

The Role Of Geospatial Thinking And Geographic Skills In Effective Problem Solving With Gis: K-16 Education, Niem Tu Huynh

Theses and Dissertations (Comprehensive)

Effective use of a Geographic Information System (GIS) is hampered by the limited geospatial reasoning abilities of students. The ability to reason with spatial relations, more specifically apply geospatial concepts, including the identification of spatial patterns and spatial associations, is important to geographic problem solving in a GIS context. This dissertation examines the broad influence of three factors on GIS problem solving: 1) affection towards computers, geography, and mathematics, 2) geospatial thinking, as well as 3) geographic skills.

The research was conducted with 104 students in Waterloo, Ontario, Canada. Students were drawn from four educational levels: grade 9 students, 13 …
