Alone in Power
The thesis uses three case studies of President Nixon’s foreign policy in South-east Asia to analyze presidential domestic-making. The theoretical concept of personality politics is used to analyze the Nixon administration and foreign policy. Nixon’s secretive nature combined with his mistrust of the press and bureaucracy to create an office structure that restricted the involvement and notification of others of his foreign policy. This thesis also takes into account the domestic climate that Nixon was operating within, including significant antiwar opposition, an adversarial media, and an ideologically opposed bureaucracy. Nixon’s foreign policy was ultimately the result of a perfect storm of factors. The president’s natural penchant for secrecy, along with his mistrust of the press and bureaucracy, combined with the American political environment that was in many instances ideologically set against him, also helped shape his foreign policy.

Along the Path
This thesis is written in three parts and supported throughout by feminist critical pedagogical analysis and a narrative methodological approach. In Part I I lay a theoretical groundwork that weaves the Freirean roots of critical pedagogy with its more contemporary theories in application to K-12 schooling, and with feminist thinking, most notably Sara Ahmed whose work has moved me both as a human and a teacher. In Part II, I take a deep dive into autoethnography (Bochner, (2017), Ellis, 1999). In Part III, I offer a memoir of my experience as a classroom teacher over a nearly 20 year period. The story of my work as an activist elementary school teacher oscillates between phases of hope and despair around the potential for forwarding a broad range of social and ecological justice ends through teaching and learning in the Ontario public school system. Finally, in Part IV, I return to conceptual analysis to reflect on the key themes of my memoir including teacher burnout, teacher efficacy, teacher resilience, and the ways in which these interact with teacher learning communities, school cultures and the relationships that underpin the work of teachers and educators.

Alpha and Omega
Game texts present unique and dynamic opportunities for lability: how readers can make choices while reading that alter the narrative's nature or outcome. Labile decisions are neither simply correct nor incorrect--the reader renders judgement to produce a desired outcome. When encountering labile challenges, players employ an interpretive strategy to resolve them. Many game texts tell stories. Games anticipate readers' interpretive strategies to orchestrate a desired result in labile narratives and manipulate players into inhabiting an identity in a variety of different ways. This thesis examines how Fallout 3 does so with periodically opposable intentions, mainly applying an inconsistent moral orthodoxy via the player character's father, but occasionally exhibiting the series' nihilistic philosophy that disdains American exceptionalism, undermining the orthodoxy. This isolates and breaks down the interpretive communities the player inhabits to play the game. Author Keywords: Exceptionalism, Identity, Lability, Morality, Narrative, Video Games
Altered Hippocampal Regulation of Immediate Early Genes after Pentylenetetrazol-Induced Seizures
Seizures induce long-term changes in gene expression in the hippocampus. Experimental evidence has demonstrated a significant effect of epileptic activity on the activity of neurons that participate in complex cognitive and behavioural processes. The present series of experiments involving kindling with subconvulsive doses of PTZ demonstrates a link between seizures and altered immediate early gene expression within the hippocampus and dentate gyrus. In addition, newborn hippocampal neurons were shown to have decreased induction of plasticity-related genes, suggesting deficits in activity-dependent recruitment. These findings may shed light on the mechanisms underlying epileptogenesis and epilepsy-related hippocampal dysfunction in human patients. Author Keywords: hippocampus, IEGs, kindling, neurogenesis, seizures
American Acropolis, American Ruins
Since 1979, photographer and sociologist Camilo José Vergara has taken repeat photographs of American cities in decline, focusing on evolving landscapes of postindustrial decay. Vergara's images subscribe to an aesthetic of ruin while providing a record of America's crumbling ghettos rooted in social documentary concerns. Vergara's work diverges from the ahistorical tendencies of contemporary ruin porn photography: by challenging the photograph's temporal stasis Vergara bears witness to the ongoing reality of disenfranchisement, assembling an archive that takes up the Benjaminian task of doing history in images. Vergara's photographs challenge standard photojournalistic portrayals of violence, particularly the ways in which `violent' African American and Hispanic inner city populations have been erroneously cast as the cause of their own economic misfortune. The Invincible Cities website assists Vergara in drawing attention to forgotten places but also complicates his mandate to engage outside viewers by distancing them from the real-­world environments his photographs portray. Author Keywords: Camilo José Vergara, imagistic history, postindustrial decline, repeat photography, ruin porn, Walter Benjamin
An Analysis of Hafted Biface Variability in the Kawartha Lakes and Trent River Drainage Region
The objective of this thesis is to evaluate the temporal sensitivity of morphological variability in hafted bifaces in the Kawartha Lakes and Trent River drainage region. This provides a base of information that will enable future analyses that address the possible sources of this variability and to test the robustness of existing typological categories of hafted bifaces for relative dating. This base of information is established via the use of a principal component analysis of shape, raw material, and use-life data from a large sample of hafted bifaces in the region, using a new geometric morphometrics method designed to improve the accuracy of shape representation. The results of the analysis indicate that while certain typological categories may represent distinct morphotypes that are temporally sensitive, the majority of typological categories in the sample show high, overlapping morphological variability that cannot be confidently correlated temporally based on shape alone.

An Analysis of Zoning By-laws and Urban Agriculture in the City of Peterborough, Ontario
Urban agriculture (UA) is becoming increasingly prevalent in Canadian cities. Despite this municipal zoning by-laws often do not address UA explicitly. Using eleven interviews of urban agricultural participants a case study of the City of Peterborough’s zoning by-laws and the barriers they might present to UA was conducted. Research suggests that UA can provide many benefits to urban areas. The analysis found that the City of Peterborough’s zoning by-laws do not directly address UA. In order to enable the development of UA in the City of Peterborough its zoning by-laws will need to be redesigned to address and regulate UA directly. Author Keywords: By-laws, food systems, land use, municipal planning, urban agriculture, zoning
An Application of Virgilio Enriquez's Indigenization Method on Filipino-Canadian Discourse
In Disturbing Invisibility (Coloma, McElhinny, Tungohan, Catungal, Davidson, 2012), the most comprehensive book on Filipino-Canadian studies to date, issues were identified in the afterword as to how Filipino-Canadian studies relates to indigenous identity. This thesis attempts to address this issue by applying Enriquez’s (1992) Indigenization Method onto Filipino-Canadian discourse. It attempts to do this by: exploring the colonial context and history in the Philippines and its effect on the formation of a Filipino indigenous identity; exploring Filipino indigenous thought as described by Enriquez (1992) in his seminal book From Colonial to Liberation Psychology; understanding Filipinos in Canada with the inclusion of literature from Filipino-American studies and the Filipino Indigenization movement; and how orienting Filipino-Canadian discourse with the indigenous concepts brought forward by Enriquez might look like, with emphasis on how Filipino-Canadian discourse could interact with Indigenous issues relating to Indigenous People in Canada today. It becomes clear that the Filipino Indigenization movement has reached grassroots Filipino organizations in Canada, and that uncritically ignoring their own Filipino indigenous roots would be denying themselves the unique cultural gifts that those roots provide. As being both Filipino and Canadian, Filipino-Canadians who seek to reclaim their indigenous roots would find that the indigenous concept of kapwa (“the self in the other”) would encourage an examination of issues pertaining to Indigenous People in Canada as commonalities exist in their experiences with colonization. Author Keywords: Canada, discourse, Filipino-Canadians, indigenization, indigenous, Philippines
An Application of the Sinc-Collocation Method in Oceanography
In this thesis, we explore the application of the Sinc-Collocation method to an oceanography model. The model of interest describes a wind-driven current with depth-dependent eddy viscosity and is formulated in two different systems; a complex-velocity system and a real-value coupled system. In general, the Sinc-based methods excel over other traditional numerical methods due to their exponentially decaying errors, rapid convergence and handling problems in the presence of singularities at end-points. In addition, the Sinc-Collocation approach that we utilize exploits first derivative interpolation, whose integration is less sensitive to numerical errors. We present several model problems to demonstrate the accuracy, and stability of the method. We compare the approximate solutions determined by the Sinc-Collocation technique with exact solutions and also with those obtained by the Sinc-Galerkin approach in earlier studies. Our findings indicate that the method we utilized outperforms those used in past studies. Author Keywords: Boundary Value Problems, Eddy Viscosity, Oceanography, Sinc Numerical Methods, Wind-Driven Currents
An Assessment of Spatial Trends in the Accumulation of Oil Sands Related Metals in the Clearwater River Valley and Temporal Trends in Six Northern Saskatchewan Lakes
The objective of this thesis was to assess current spatial trends and historic trends in the accumulation of trace metals related to the Athabasca Oil Sands Region (AOSR). The AOSR hosts some of the largest industrial developments in Canada, yet relatively little is known about the transport and fate of trace metal emissions from the region – particularly in the relatively remote areas to the east of the AOSR. Lichens are widely used as biomonitors and are employed in this thesis to assess the range of metals deposition within the Clearwater River and Athabasca River Valleys. Lake sediment cores can retain a historical record of the long-range transport and deposition of metals but can also respond to large regional metal emissions sources. This thesis used lake sediment cores to assess temporal trends in metals accumulation in six road accessible lakes in NW Saskatchewan that are likely to be used by local residents. Results show that metal concentrations (V, Co, Cu, Ni, Pb, Zn, Zr and Cd ) in lichen decline exponentially with distance from the AOSR and approach background levels within a few kilometers . Results from lake sediment cores show that there was no evidence that metal concentrations had increased due to industrial activities in the AOSR. Author Keywords: Air Emissions, Lakes, Lichens, Oil Sands, Saskatchewan, Trace Metals
An Ecological Analysis of Late Woodland Settlement Patterns in the Rouge River Watershed, Southern Ontario
This thesis seeks to understand the influences of environmental variables on site location selection during the Late Woodland period (ca. A.D. 1000-1650) in south-central Ontario, specifically variables considered to be favourable to maize agriculture. Four analyses were undertaken: a geographic information system (GIS) comparative analysis of Late Woodland sites compared to random points; population estimates of four sites for which settlement pattern data was available; maize consumption estimates for these same sites, and; a maize resources catchment analysis of these sites. The analysis conducted did not produce conclusive results to answer questions related to maize-driven site selection, however it did show that requirements for maize resources at these sites could have been met in catchment areas of a 500 m radius, in one case in 250m. The results led to an important question for future research: if agricultural needs were not driving settlement location selection in this area, what was?

An Emergent Model of the Return to Learn Process for Adolescents with Prolonged Concussion
Current literature on concussion management focuses primarily on the return to physical activity, while the return to learn process is less clearly understood. This knowledge gap is particularly problematic for adolescents, whose primary responsibility is academics. The present study sought to develop a more in-depth understanding of the return to learn process through the perspectives of adolescents who had sustained a concussion and their parents in in-person, semi-structured interviews. A substantive grounded theory of the return to learn process for adolescents that emerged from the data is provided. The basic model is consistent with many speculative, non-empirically based concussion management protocols, but extends these models by emphasizing the central role of parents in managing their child’s recovery process, highlighting the importance of role fulfillment within the concussion management network, and identifying the impact of the adolescent’s capacity and readiness for help-seeking. The results also highlight the vulnerability of concussed adolescents to losing their support structure as they move through key school transitions. Implications for educators, medical professionals, parents, and adolescents in the return to learn process are also discussed. Author Keywords: Adolescent, Concussion, Concussion Management, Multidisciplinary Management, Return to Learn, Return to School
