Assessing the Management of Public Private Partnerships In Infrastructure Procurement: A Complex Evolutionary Systems Theory Perspective

Blair Parsons
This dissertation focuses on the findings of a multi-case study centered around two public-private partnership (P3s) projects in Ontario: the Royal Ottawa Hospital and the Brampton Civic Hospital. Partnerships have become particularly important as a part of infrastructure procurement for all levels of government in Canada. While infrastructure public-private partnerships have grown in popularity, they remain a controversial means of procuring public assets. Considerable questions remain as to whether the mechanisms related to partnerships with...

Physiological and Behavioral Changes in a Rotenone Model of Dopamine Neurotoxicity and Neurodegeneration in Zebrafish

Jonathan Keow
Rotenone is a commercially available pesticide with a variety of industrial applications. However, occupational exposure to rotenone has been implicated in the development of Parkinson’s disease. To explore the mechanism of dopamine neuron death secondary to rotenone exposure, the zebrafish was used as a live animal screening tool for environmentally-induced Parkinson’s disease. After testing a variety of small molecule compounds on embryonic zebrafish for their potential to cause dopamine neuron loss, we identified that rotenone...

Tsunami Vulnerability Assessment of the Canadian Pacific Coast

Isabelle Cheff
The North American Pacific coast, located within the Ring of Fire, is at risk of severe subduction tsunamis. This danger has pushed the United States to make a strong push in tsunami research. Recent advancement has resulted in the implementation of a new chapter in the ASCE 7-16 standards focusing on tsunami structural loads and effects. Within the scope of this new standard, the tsunami inundation hazard of the US West coast has been mapped....

Aerodynamic Characteristics of Yawed Inclined Circular Cylinders

Michael Shane Hoftyzer
The wind-induced vibration of bridge stay cables has been a long studied and documented topic including a vast literature presenting experimental and numerical investigation results. There are several aerodynamic phenomena which can be associated with the wind-induced vibrations of bridge stay cables, such as vortex-induced vibration, rain-wind induced vibrations, buffeting phenomenon, dry cable galloping, and high-speed vortex excitation, to name a few. One of the most critical types of vibrations for slender structures exposed to...

The Untold Stories of Women Soccer Referees

Kamiel Reid
In Canada, women’s soccer has continuously grown and developed, however women continue to be under represented in non-playing roles – particularly as referees (Canadian Heritage, 2013; Canadian Soccer Association, 2013a; Ontario Soccer Association, 2012). Of the 20,507 soccer referees in Canada, only 24% are women (Canadian Soccer Association, 2013a). Moreover, 54% of Canadian soccer referees are registered in Ontario (Ontario Soccer Association, 2012), of which only 9.5% are women (Ontario Soccer Association, 2013). This study...

Representing the Invisible? An Intersectional Analysis of Incarcerated Women in Netflix's Orange is the New Black

Jamie Gesualdo
Criminalized women are becoming more prominent in the prison show genre, outlining the need to examine the possible troublesome portrayals of this often invisible population. This thesis uses intersectionality to conduct a qualitative content analysis to explore themes of race, class, gender, and sexuality in relation to woman characters within the popular series Orange is the New Black (OITNB). It is found that OITNB is a departure from most mass media depictions of criminalized women...

Voltaire's \"Candide\" and the Methodology of Dramatic Adaptation

Catherine Ballachey
This thesis details the search for dramaturgical methodologies of adaptation with the additional component of a creative project used to put those methodologies into practice. In particular, my research has been focused on the methodologies available for transforming static or descriptive moments of literature into compelling works of drama. My discussion on this process begins by tracing the scholarly developments in the field of adaptation studies, which have led away from what Linda Hutcheon calls...

\"But oh, I could it not refine\": Lady Hester Pulter's Textual Alchemy

Pricilla Padaratz
Hester Pulter addresses personal and spiritual transformation in a unique way. The elusive nature of alchemical language allows Pulter to express the incomplete, ongoing process of internal transformation, with all its difficulties and inconsistencies. By means of a rich alchemical lexicon, Pulter stresses suffering rather than consolation, conflict rather than reconciliation, and lack of resolution rather than closure in her poetry. She repeatedly tries to see a divine order in earthly suffering, but she insists...

Investigation of VARTM Resin Flow Through 3D Near Net-Shape Aerospace Preforms

Francois Proulx
The manufacturing of complex aerospace carbon epoxy components remains dominated by processes involving prepreg cured in autoclaves. This manufacturing route is expensive, not only because prepreg precursor materials have short shelf lives and require refrigerated storage, but also because large autoclaves carry very high operating costs and are in very intensive usage, with limited worldwide availability. Vacuum Assisted Resin Transfer Moulding (VARTM) is an interesting alternative for the manufacturing of near net-shape components as it...

L’objectif du projet était de sensibiliser des personnes de 65 ans et plus, hypertendues, en milieu francophone minoritaire aux facteurs de risque de l’hypertension par des ateliers éducatifs. L’impact de ces ateliers a été mesuré par un questionnaire sur la qualité de vie et...

Childbirth Decision Making Processes: Influences on Mode of Birth After a Previous Caesarean Section

Esther Susanna Shoemaker
Background: An increasing proportion of Canadian women are experiencing a Caesarean section (CS) and a subsequent repeat CS. While CS can be necessary and lifesaving for mothers and their infants in some situations, it is also associated with greater morbidity risks to women and infants than vaginal birth. Clinical practice guidelines recommend the involvement of pregnant women in making decisions about mode of birth and shared decision making improves the informed consent process. This research...

The Role of Temperature in Timing of Reproduction and Reproductive Success of Gray Jays, Perisoreus canadensis

Shannon Whelan
Although early reproduction within a breeding season often leads to higher reproductive success in seasonal environments, it is still not well understood how reproductive success can be influenced by climate both indirectly through the timing of breeding or by directly altering parental behaviour. In this thesis, I investigate the role of ambient temperature in reproductive success through its effects on the timing of reproduction and brooding in a population of gray jays, Perisoreus canadensis. In...

Essays in Health and Income Dynamics

Duangsuda Sopchokchai
This thesis consists of two related chapters and one unrelated chapter. The first focuses on the health of immigrants in Canada, using the most up-to-date Canadian Community Health Surveys (CCHS). I re-investigate the previously well-established Healthy Immigrant Effect (HIE)--the finding that upon arrival, immigrants are relatively healthier than the native-born population; but that this health advantage declines over the years after migration. Measures of health used in this study include self-assessed health status, the likelihood...

Evaluation of a Sports-Based Positive Youth Development Program for First Nations Youth: Experiences of Community, Growth and Youth Engagement

Tanya Halsall
In contrast with mainstream Canadian youth, First Nations youth experience many health disparities. Researchers recommended that interventions designed to promote First Nations youth development use a strengths-based lens that recognizes contextual challenges. Furthermore, leadership programming for First Nations youth has begun to show promising outcomes. The overall purpose of this research was to examine the Youth Leadership Program (YLP) program to gain an understanding of program implementation and perceived outcomes related to both individual and...

Group Cognitive Behavioural Therapy for Depression: A Preliminary Analysis of the Role of Feedback and Process in Treatment Outcomes

Mandisa V. Peterson
Background: Group CBT approaches have been shown to be equally as effective as individual CBT for reducing depressive symptoms and preventing relapse; however, the predictors of response are poorly understood. The primary objective of the studies presented in this thesis was to further examine the formal and process factors within group CBT for depression that contribute to various treatment outcomes. The first study investigated the relationship between group CBT for depression and changes in interpersonal...

Gender Performativity in Nursing; Men, Power and the Construction of the Ideal Nurse

Barbara Le Blanc
This study explores the pedagogical experience of male nursing students. Research questions explored male students being subjected to feminine gender performance expectations, and an inequitable exercise of power and discipline and the relation of high attrition rates of male nursing students to feminine gender performativity expectations. The framework utilized included Butler's theory of gender performativity, Foucault's concepts of power and discipline and Queer theory. A Van Manen phenomenological method was utilized, with interviews of 20...

Evaluating Multi-level Risk Factors for Malaria and Arboviral Infections in Regions of Tanzania

Esha Homenauth
Vector-borne diseases, such as those transmitted by mosquitoes, pose a significant public health concern in many countries worldwide. In this thesis, I explored the role of a number of risk factors defined at multiple scales on vector-borne disease prevalence, focusing on malaria and arboviral infections in several regions of North-Eastern Tanzania, with the principal aim of improving the overall diagnosis of febrile illness in this region. First, I investigated the influence of household-wealth on prevalence...

Understanding and Characterizing Excited State Electron Transfers in Catalysis and Nanomaterial Synthesis

Christopher Darrell McTiernan
Over the past decade, there has been an ever-increasing interest in photochemical redox processes as a tool in organic syntheses. While the underlying mechanism of many of these transformations involves free radicals, the complex product mixtures and poor selectivity that are traditionally associated with these types of reaction can be in most cases avoided. In fact there are numerous examples of photoredox catalysis, which demonstrate that under well-selected conditions it is possible to obtain relatively...

Evolutionary Game Theory and the Spread of Influenza

Marc A. Beauparlant
Vaccination has been used to control the spread of infectious diseases for centuries with widespread success. Deterministic models studying the spread of infectious disease often use the assumption of mass vaccination; however, these models do not allow for the inclusion of human behaviour. Since current vaccination campaigns are voluntary in nature, it is important to extend the study of infectious disease models to include the effects of human behaviour. To model the effects of vaccination...

A Field and Petrological Study of Oxide-Facies Algoma-Type Banded Iron Formation, Sherman Mine, Temagami

Stephen Ginley
Banded iron formation (BIF) is the most commonly mined source of iron ore, but the details of its genesis are poorly defined. Algoma-Type BIF is a predominantly chemical sedimentary rock comprising iron-rich phases (hematite, magnetite, chlorite) and chert as distinct laminae associated with deep marine lithologies, especially volcanic rocks and black shales. The iron minerals are thought to be direct chemical precipitates from Fe-enriched bottom waters or formation waters, most probably related to proximal volcanic...

Anisotropic Residual-Based Mesh Adaptation for Reaction-Diffusion Systems: Applications to Cardiac Electrophysiology

Edward Boey
Accurate numerical simulation of reaction-diffusion systems can come with a high cost. A system may be stiff, and solutions may exhibit sharp localized features that require fine grids and small time steps to properly resolve the physical phenomena they represent. The development of efficient methods is crucial to cut down the demands of computational resources. In this thesis we consider the use of adaptive space and time methods driven by a posteriori error estimation. The...

« Préférez-vous votre oeil droit ou votre oeil gauche? » : Langue et religion dans le débat sur la gestion scolaire en Ontario français (1969-1998)

Danika Gourgon
Cette étude fait l’examen de la place de la religion catholique dans le débat sur la création des conseils scolaires francophones et, plus largement, dans le débat public franco-ontarien entre 1969 et 1998. Elle tente d’apporter certaines nuances à la thèse de l’« éclatement » du Canada français et de l’écartement de la référence canadienne-française que la plupart des chercheurs ont soutenue jusqu’à présent. En analysant les discours formulés et les actions menées par les...

Improving the Delivery and Replication of Oncolytic Viruses

Dominic Roy
The optimal route for clinical delivery of oncolytic viruses (OVs) is thought to be intravenous (IV) injection; however, the immune system is armed with several highly efficient mechanisms to remove pathogens from the circulatory system. To overcome the challenges in trying to deliver OVs IV, cell carriers have been investigated to determine their suitability as delivery vehicles for systemic administration of OVs. Here we demonstrate the utility of a Drosophila melanogaster cell platform for the...

Influenza Virus Evades NK Cell Responses by Enhancing Ly49:MHC-I Interactions

Ahmad Bakur Mahmoud
Natural killer (NK) cells are a type of innate immune cell that can identify and eliminate viral infected cells and cancer cells. NK cells express an array of inhibitory and activating receptors such as natural cytotoxicity receptors, the mouse Ly49 or human KIR family, and NKR-P1 family. The integration of signals that NK cells receive through these receptors controls their activation and ability to kill target cells. Both Ly49 and KIR recognize MHC-I molecules on...
