Branding of the Prime Minister
From 1949-1957, Prime Minister Louis St. Laurent was the face of the Liberal Party. Party branding was wholly devoted to his friendly, ‘Uncle Louis’ brand image. St. Laurent’s image was manipulated and manufactured without public preconception, establishing the modern tactics of personal branding still used by his successors. This thesis studies the elections of 1949, 1953, and 1957, analysing photos, advertisements, speeches, archival documents, memoirs, newspapers, and other sources to show the development of Liberal branding strategy. It employs political scientist Margaret Scammell’s conceptualization of brand theory, showing how marketers used emotional brand differentiators and rational substantive performance indicators to sell ‘Uncle Louis’ to Canadians. The Liberals used St. Laurent and branding tactics to win two massive majorities in 1949 and 1953, and the Diefenbaker Tories used those same tactics to defeat them in 1957. ‘Uncle Louis’ proved the effectiveness of personal branding and leader-centered campaigns in Canadian politics.

'This is where the poetry comes out'
Since 1984, poetry slams have emerged as a politicized expressive movement of performing the personal and political through poetry competitions. Slams are also discursively spatialized, often represented as “spaces” that are “safe,” “inclusive,” etc. In this thesis, I investigate how, why, and to what effect the Peterborough Poetry Slam produces, consolidates, and challenges such “resistant spaces.” Drawing on interviews and participant observation, I consider how the slam’s reiterative practices facilitate its space-making by encouraging performances that resist, reimagine, and sometimes inadvertently reify dominant societal norms. I argue that this space-making is imperfect yet productive: though not resistant space in any straightforward or static way, the slam continuously produces possibilities to challenge norms and confront power. This thesis contributes to scholarship on performative space and creative resistance movements. In an era when political resistance to power structures is often silenced, this research offers insights of potential significance to other resistant space-makings. Author Keywords: Nogojiwanong Peterborough, performative space, poetry slam, resistance, space-making, spoken word
Effects of biodiversity and lake environment on the decomposition rates of aquatic macrophytes in the Kawartha Lakes, Ontario
Decomposition of aquatic macrophytes has an important role in defining lake carbon (C) storage and nutrient dynamics. To test how diversity impacts decomposition dynamics and site-quality effects, I first examined whether the decomposition rate of aquatic macrophytes varies with species richness. Generally, I found neutral effects of mixing, with initial stoichiometry of component species driving decomposition rates. Additionally, external lake conditions can also influence decomposition dynamics. Therefore, I assessed how the decomposition rate of a submersed macrophyte varies across a nutrient gradient in nine lakes. I found decomposition rates varied among lakes. Across all lakes, I found Myriophyllum decomposition rates and changes in stoichiometry to be related to both nutrients and water chemistry. During the incubation changes in detrital stoichiometry were related to lake P and decomposition rates. Aquatic plant community composition and stoichiometry could alter decomposition dynamics in moderately nutrient enriched lakes.

Disability-Mitigating Effects of Education on Post-Injury Employment Dynamics
Using data drawn from the Workplace Safety and Insurance Board’s (WSIB) Survey of Workers with Permanent Impairments, this thesis explores if and how the human capital associated with education mitigates the realized work-disabling effects of permanent physical injury. Using Cater’s (2000) model of post-injury adaptive behaviour and employment dynamics as the structural, theoretical, and interpretative framework, this thesis jointly studies, by injury type, the effects of education on both the post-injury probability of transitioning from non-employment into employment and the post-injury probability of remaining in employment once employed. The results generally show that, for a given injury type, other things being equal, higher levels of education are associated with higher probabilities of both obtaining and sustaining employment. Author Keywords: permanent impairment, permanent injury, post-injury employment
Variation in the δ15N and δ13C composition of POM in the Lake Simcoe watershed
The purpose of this study was to quantify the variation of baseline carbon and nitrogen stable isotope signatures in the Lake Simcoe watershed and relate that variation to various physicochemical parameters. Particulate organic matter samples from 2009 and 2011 were used as representatives of baseline isotopic values. Temporal data from two offshore lake stations revealed that δ15N of POM was lowest mid-summer and highest after the fall turnover. POM δ13C was variable throughout the summer before declining after fall turnover. Spatial data from the lake and the tributaries revealed that POM stable isotope signatures were highly variable. Various physicochemical parameters indicative of phytoplankton biomass were significantly positively correlated with POM δ15N and significantly negatively correlated with POM δ13C. The correlations were mostly significant in the tributaries, not the lake. Moreover, many of the correlations involving δ15N of POM were driven by extreme values in Cook's Bay and its tributaries. In general, it's likely that different processes or combination of processes were affecting the δ15N and δ13C POM in the Lake Simcoe watershed as physicochemical parameters alone could not explain the variability. Measuring the δ15N of ammonium and nitrate, as well as the δ13C of DIC would help discern the dominant nitrogen and inorganic carbon cycling processes occurring in the Lake Simcoe watershed. Author Keywords: δ13C, δ15N, isotopic baseline, particulate organic matter, spatial variation, stable isotopes
Assessing Connectivity of Protected Area Networks and the Role of Private Lands in the United States
Forestalling biodiversity loss through the establishment of protected areas is a universally accepted conservation strategy, yet despite established guidelines for protected area coverage and placement, much of the world is currently failing to meet its commitments to conservation planning and landscape protection. Calls for the United States to protect more land usually focus on the need for strategic selection of land parcels to bolster protected area coverage and network functionality, but to date there lacks focused research on either the role of private protected areas in conservation planning or the factors affecting individual protected area selection and importance. We determined gaps in conservation planning in the contiguous United States by analyzing the connectivity of protected area networks by state, and assessing the importance of private protected areas in improving linkages in protected area connectivity. We found that all states had low coverage from protected areas (average <8.4% of total land mass), and especially private protected areas (average <1.1% of total land mass), and that the overall contribution of such areas to protected area network connectivity also was low. Terrain ruggedness was identified as the main factor affecting the current location of protected areas, and that protected area spatial layout is a primary influence on landscape connectivity. We conclude that establishment of private protected areas could offer a viable conservation tool for increasing protected area coverage and connectivity, but that current efforts are inadequate to either adequately link existing protected areas or to meet established land protection guidelines.

Sustainable Development and Environmental Security in the Canadian Arctic
This study identifies and examines interlinkages between climate change and sustainable development, environmental security, and adaptive capacity through a case study of two communities in the Inuvialuit Settlement Region: Inuvik and Tuktoyaktuk. It seeks to understand how these two communities perceive climate change and define sustainable development, particularly in relation to oil and gas development. This thesis discusses the constraints that may be arising for local communities to benefit from emerging opportunities due to competing notions of sustainable development and environmental security. The findings indicate how notions of environmental security and sustainable development act upon multiple levels to impact the adaptive capacity of communities in the Arctic. The general findings also suggest that regionally specific understandings of sustainable development, sustainability, and environmental security need to be acknowledged in order to develop successful governance coordination and cooperation strategies and paradigms related to economic, social, infrastructure and environmental issues in the NWT and the Canadian Arctic. Author Keywords: Arctic, Beaufort Sea, climate change, Environmental Security, Inuvialuit, Sustainable Development
Ceramic Analysis of Jacob Island 2
The goal of this thesis is to develop an understanding of the history of Middle and Late Woodland settlement at Jacob Island, located in Pigeon Lake in the Trent River region, through analysis of ceramic artifacts recovered during the 2016 excavation program. Using both typological and attribute based analysis. The results indicate a form of seasonal occupation. The ceramic patterning on site is broken down and fully examined for intra-site patterning and compared to concurrent regional examples. The regional comparison is carried out through statistical testing of independence. The results demonstrate both continuity and a pattern that is different than the surrounding region, supporting the concept of different expressions of materiality. These findings place JI-2 in a broader context with contemporary research in the South Eastern areas of Ontario and, in particular, the Trent River region.

Epicentres, Elites, and Entanglement
This thesis investigates the similarities and differences between the tropical epicenters of South and Southeast Asia during the Charter State era, 800- 1400 CE. This study can inform scholars about the relationship between “people and place” by examining the ground plans, activities, and people associated with each epicenter. By using the comparative approach and entanglement theory, this study will examine the ancient states of Central and East Java, Dai Viet in North Vietnam, the Cham in Central Vietnam, the Chola of South India, and the Sinhalese of Sri Lanka. The ancient Maya of tropical Belize will be used as a cross-cultural comparator, which would not have had any contact with the other charter states. An extensive literature review and on-site visitations were necessary to provide the background and date to accomplish these goals. The results indicate striking similarities between tropical epicenters across the Charter States that developed out of the entanglements between humans and things. This thesis will help to further our understanding of tropical urbanism and the nature of epicenters in tropical environments.

Factors Controlling Peat Chemistry and Vegetation Composition in Sudbury Peatlands after 30 Years of Emission Reductions
Peatlands are prevalent in the Sudbury, Ontario region. Compared with the well documented devastation to the terrestrial and aquatic ecosystems in this region, relatively little work has been conducted on the peatlands. The objective of this research was to assess factors controlling peat and plant chemistry, and vegetation composition in 18 peatlands in Sudbury after over 30 years of emission reductions. Peatland chemistry and the degree of humification varies considerably, but sites closer to the main smelter had more humified peat and the surface horizons were enriched in copper (Cu) and nickel (Ni). Copper and Ni concentrations in peat were significantly correlated with Cu and Ni in the plant tissue of leatherleaf, although the increased foliar metal content did not obviously impact secondary chemistry stress indicators. The pH and mineral content of peat were the strongest determining factors for species richness, diversity and community composition. The bryophyte communities appear to be acid and metal tolerant, although Sphagnum mosses are showing limited recovery. Author Keywords: anthropogenic emissions, bryophytes, community comspoition, heavy metals, peatlands, wetland vegetation
GIS-based Spatial Analysis of Visibility and Movement Using the Ancient Maya Center of Minanha, Belize
It has long been hypothesized the location of the ancient Maya center of Minanha was a strategic one based on its ability to control the flow of communication and key resources between major geopolitical zones. Situated in the Vaca Plateau, at the nexus of the Belize River Valley, the Petén District of Guatemala, and the Maya Mountains, Minanha became a Late Classic polity capital that was tapped into a regional economy as well as long-distance trade networks. In this thesis I present a GIS-based spatial analysis that includes viewshed and cost surface analysis (CSA) to model visibility and movement within the north Vaca Plateau and neighboring regions to address specific questions concerning Minanha's strategic value. The results indicate that Minanha occupied a visually prominent location in proximity to major corridors of movement that suggest it was strategically, and in fact ideally located, as a polity capital with the ability to monitor the movement of people and resources. Author Keywords: Belize, GIS, Least Cost Path, Maya, Minanha, Viewshed
Agro-Ecological Zoning (AEZ) of Southern Ontario and the Projected Shifts Caused by Climate Change in the Long-term Future
This thesis proposes an agro-ecological zoning (AEZ) methodology of southern Ontario for the characterization and mapping of agro-ecological zones during the historical term (1981-2010), and their shifts into the long-term (2041-2070) projected climate period. Agro-ecological zones are homogenous areas with a unique combination of climate, soil, and landscape features that are important for crop growth. Future climate variables were derived from Earth System Models (EMSs) using a high emission climate forcing scenario from the Intergovernmental Panel on Climate Change 5th Assessment Report. The spatiotemporal shifts in agro-ecological zones with projected climate change are analyzed using the changes to the length of growing period (LGP) and crop heat units (CHU), and their manifestation in agro-climatic zones (ACZ). There are significant increases to the LGP and CHU into the long-term future. Two historical ACZs exist in the long-term future, and have decreased in area and shifted northward from their historical locations. Author Keywords: Agro-climatic Zones, Agro-ecological Zones, Agro-ecological Zoning, Climate Change, Crop Heat Units, Length of Growing Period
