Controlling the Feminine Body in Public
Within this project, I have identified a new pattern of instruction, surrounding women’s bodies and their movement within the public space, present within didactic literature produced during the reign of Charles VI of France (1368-1422). This pattern, present in the texts Le livre du Chevalier de la Tour Landry pour l’instruction de ses filles, Le Menagier de Paris, Le livre des trois vertus and Mirroir des dames, sought to shame control women’s physical presentation in public through use of imagery, stories and fear of pride. Using modern gendered body theory presented by Luce Irigaray and Judith Butler to examine the rise of this pattern, this project then concludes it represents an attempt of the social authority to present a passive feminine body in the public space in order to display male power during a time of social instability.

Why do landowners restore wetlands? A case study from east central Ontario
Wetlands were once widespread in southern Ontario, but many have been drained through land use changes. Using a case study of twelve landowners in the Kawartha region, I explored motivations for restoring wetlands. Psychological research suggests that people who are more connected to nature and attached to place are more likely to behave sustainably. Results showed that having land available and receiving funding were necessary preconditions. Connectedness to nature and place attachment were motivations, as were personal benefits and having a supportive social community. Challenges included: the Permit to Take Water, paperwork and bureaucracy, delays and timing, and economic restrictions. Positive outcomes were: increased property value and crop productivity; personal enjoyment of wetlands; and improved wildlife habitat and water quality. Negative outcomes were: `nuisance' wildlife, trespassing, and a lack or excess of water. This is a novel study exploring nature connectedness, place attachment and wetland restoration qualitatively in southern Ontario.

Towards a Critical Pedagogy of Globality
In this thesis, I use “Trump’s Wall” between Mexico and the US to resist Eurocentrism and the challenges Eurocentric pedagogy poses to the research-practitioner. In my method, I reimagine C. Alejandra Elenes’ borderlands theory as a zone of empowerment within a multicultural Canadian classroom, and braid it in a hybrid assemblage with the rhizome. The “rhizo-borderlands” assemblage uses selected field notes gleaned from my teaching practice to develop themes of a critical pedagogy of globality in personal, local and international dimensions. These are further braided with a “day-in-the-life” narrative of a fictionalized student (Ellie) who navigates her way towards a world literature classroom where the focus is The Kite Runner by Khaled Hosseini. This assemblage affirms my belief that teaching and learning provides a context where students become “border crossers” and navigate points of intersection between their local and global selves, in order to develop intercultural competencies.

Range dynamics of two closely related felids
Species ranges are changing and the rate at which the climate is warming is faster than anything previously seen in the past, consequently species will need to adapt quickly, track the climate or perish. Cold adapted terrestrial species are the most vulnerable, because they are limited by the availability of land at the cold edge of their range. This means that many alpine, boreal and polar species essentially have nowhere to go as the climate warms. Habitat generalists are widely distributed across the globe and are highly adaptable to anthropogenic change. Our future biodiversity may only consist of several habitat generalists. The Canada lynx (Lynx canadensis) is a boreal species that has limited range expansion potential at the cold end of its range and its range has already contracted by 40%. The lynx has nowhere to go as climate warming progresses in this current century. Therefore, understanding the causes of its range contraction could enlighten us on conservation and management strategies that we might undertake as climate warms. My analyses indicated that the Canada lynx seems to have tracked the habitat that it is adapted to in more northern homogenous boreal forests and the bobcat (Lynx rufus), a habitat generalist, has simply replaced it in the south.

Predictive Digital Mapping of Soils in Kitimat, British Columbia
Soil is an essential natural resource that supports provisioning services such as agriculture, silviculture, and mining. However, there is limited knowledge on forest soil properties across Canada. Digital soil mapping may be used to fill these data gaps, as it can predict soil properties in areas with limited observations. The focus of this study was to develop predictive maps of select soil physicochemical properties for the Kitimat Valley, British Columbia, and apply these maps to assess the potential impacts of sulphur dioxide emissions from an aluminum smelter, on soil properties in the Valley. Exchangeable [Ex.] magnesium, organic matter, pH, coarse fragment, Ex. potassium, bulk density, Ex. calcium, Ex. acidity, and Ex. sodium were all mapped with acceptable confidence. Time to depletion of base cation pools showed that ~240 km2 of the study area had a depletion time of 50 years or less. However, sources of base cations such as atmospheric deposition and mineral weathering were not considered.

Laughing to be Citizens
This study will focus on how immigrants from Sub Saharan African (SSA) countries use humour as a tool for integration and belonging (and ultimately citizenship) in Canada. My aim is to investigate, through a detailed analysis of popular culture productions from immigrant communities, the strategies and techniques of humour that immigrants employ as a mode of communication with fellow immigrants, their immediate host community and the governmental authorities of Canada. I am particularly interested in how African immigrants use their oral background and cultural memory in the production of jokes and other humour products as a way of interacting, first with fellow immigrants as the primary audience and recipients of the humour and, second, with Canadian society at large. Using the ‘Signifying’ theory of Henry Louis Gates (1988) and Mikhail Bakhtin’s (1968) concept of the “Carnivalesque” as the theoretical framework for this study, I argue that immigrants from SSA countries are using humour to question hegemonic regulations that portrays them as victims, while providing alternative narratives of themselves as subjects with human agency. I further postulate that immigrants are taking advantage of the policy of multiculturalism that exists in Canada in a positive manner as an enabler for their humour. In turn, they are using the humour produced to communicate and break down social barriers, while building bridges across communities and social strata. I bolster my arguments with a consideration of humour in three genres of popular culture – literature, standup comedy and film – to show how immigrants rely on their home culture to produce humour in an effort to find belonging in Canada as contributors rather than victims. This thesis is the first work to examine SSA humour, produced by immigrants from these countries, in the context of their immigration and integration into Canada, and the first to present extended literary criticism of the works of immigrant writers, Tololwa Mollel, Yabome Gilpin-Jackson and Segun Akinlolu. This is also the first study on the comedy of Arthur Simeon, originally from Uganda and the film of Phina Brooks, originally from Nigeria. My analysis apprehends the immigrant voice in the writings and productions of these artists and places their works in conversation with Canadian literary/cultural criticism. Until now, there has been no study of the function of humour produced by African immigrants in Canada. It is my hope that this study will not only fill that gap, but also lay the groundwork for future study in this field that I believe holds a lot of socio-cultural promise, especially in the area of cohesive habitation amongst different ethnic groups. This study aims to contribute to conversations on immigration and its impact on Canadian society as part of nation-building and national consciousness.

Soil mineralizable nitrogen as an indicator of soil nitrogen supply for grain corn in southwestern Ontario
Soil mineralizable nitrogen (N) is the main component of soil N supply in humid temperate regions and should be considered in N fertilizer recommendations. The objectives of this study were to determine the potentially mineralizable N parameters, and improve N fertilizer recommendations by evaluating a suite of soil N tests in southwestern Ontario. The study was conducted over the 2013 and 2014 growing seasons using 19 field sites across southwestern Ontario. The average potentially mineralizable N (N0) and readily mineralizable N (Pool I) were 147 mg kg-1 and 42 mg kg-1, respectively. Pool I was the only soil N test that successfully predicted RY in 2013. The PPNT and water soluble N (WSN) concentration (0-30cm depth) at planting were the best predictors of fertilizer N requirement when combing data from 2013 and 2014. When soils were categorized based on soil texture, the relationships also improved. Our findings suggest that N fertilizer recommendations for grain corn can be improved, however, further field validations are required.

Practicing and Rewarding Task-Relevant Motor Variability to Optimize Motor Performance
It is universally accepted that human motor performance is variable in both its timing and spatial qualities. However, it is unclear to what extent motor variability impedes performance when learning a new skill and to what extent it enables our ability to learn. The first experiment examined whether performance during a test task depended on whether participants practiced to constrain or vary the task-relevant parameter. Participants used their right hand to make simple point-to-point movements. Results demonstrated the importance of paying attention to test task demands to evaluate which form of practice is most beneficial. The second experiment examined whether levels of variability could be manipulated using a reward-based paradigm to enhance learning when adapting to a perturbation of a simple visually-guided reaching movement. A reward-based feedback task was designed to encourage exploration along the task-relevant dimension, specifically movement direction variability. Overall, I did not find any significant results.

Application of One-factor Models for Prices of Crops and Option Pricing Process
This thesis is intended to support dependent-on-crops farmers to hedge the price risks of their crops. Firstly, we applied one-factor model, which incorporated a deterministic function and a stochastic process, to predict the future prices of crops (soybean). A discrete form was employed for one-month-ahead prediction. For general prediction, de-trending and de-cyclicality were used to remove the deterministic function. Three candidate stochastic differential equations (SDEs) were chosen to simulate the stochastic process; they are mean-reverting Ornstein-Uhlenbeck (OU) process, OU process with zero mean, and Brownian motion with a drift. Least squares methods and maximum likelihood were used to estimate the parameters. Results indicated that one-factor model worked well for soybean prices. Meanwhile, we provided a two-factor model as an alternative model and it also performed well in this case. In the second main part, a zero-cost option package was introduced and we theoretically analyzed the process of hedging. In the last part, option premiums obtained based on one-factor model could be compared to those obtained from Black-Scholes model, thus we could see the differences and similarities which suggested that the deterministic function especially the cyclicality played an essential role for the soybean price, thus the one-factor model in this case was more suitable than Black-Scholes model for the underlying asset. Author Keywords: Brownian motion, Least Squares Method, Maximum Likelihood Method, One-factor Model, Option Pricing, Ornstein-Uhlenbeck Process
In situ measurements of trace metal species in the Athabasca and Mackenzie Rivers using diffusive gradient in thin films (DGT) devices
This study assesses the bioavailable metal (Cu, Ni, Zn, Pb) species in the Athabasca-Mackenzie watersheds using diffusive gradient in thin films (DGT) devices. Metal toxicity is not only based on the concentration of metal in natural waters, but also on the nature of metal species. Four main forms in aquatic systems are: free ion, inorganic species, DOM bound (humic) species and metal colloidal species. The free ion and inorganic species and very small humic species are known as DGT-labile species and, are considered to be more bioavailable to micro-organisms due to the size and thus may be toxic to microorganisms. In this study, DGT devices were applied to (1) monitor the DGT-labile metal species in the lower Athabasca River and the Mackenzie River watershed and (2) assess the DGT-labile metal concentrations on temporal and spatial scales. In the lower Athabasca River, comparison between the DGT results and the Windermere Humic Acid Model (WHAM) calculation indicated good agreements for all metals when the precipitated iron(III) hydroxide was assumed as an active binding surface. No significant variations in labile species were found over 2003-2012 (RAMP database) despite the development of oil sands. In the Mackenzie River, no significant difference in DGT-labile metal concentrations and DOC concentrations was found in yearly basis 2012-2014. Only DOC was lower in August (6.98 and 3.85 ppm, respectively; p< 0.05) due to dilution from heavy rain events. Spatially, DGT-labile Cu and Ni in the downstream Mackenzie River were higher than upstream (1.79 and 0.58 ppb for Cu, 1.68 and 0.77 ppb for Ni, 4.06 and 6.91 ppm for DOC; p < 0.05). Overall the in situ measurements of metals constitute a benchmark for future studies in water quality and be helpful in environmental management in Alberta and the Northwest Territories in Canada.

Geospatial Analysis of Late Paleoindan Hi-Lo Points in Ontario and New York
This thesis analyzes variability in a sample (n=302) of late Paleoindian Hi-Lo points from Ontario and New York. Biface variability is recorded using landmark geometric morphometrics. Raw material data is used to assess Hi-Lo toolstone usage patterns and the impact of raw material constraints on manufacture. Statistical analyses are used to assess patterning of variability in space. Spatial results are interpreted using cultural transmission theory in terms of their implications for the geographic scale of social learning among Hi-Lo knappers. Results of the spatial analyses are related to theory about hunter-gatherer social networks in order to understand the effects of hypothesized settling in processes on late Paleoindian knappers. Results indicate random spatial patterning of Hi-Lo variability. The absence of spatial autocorrelation for Hi-Lo size indicates that settling in processes were not sufficiently pronounced during the late Paleoindian period to manifest as inter-regional variability within the Hi-Lo type. Author Keywords: Biface Variability, Cultural Transmission, Geometric Morphometrics, Hi-Lo, Late Paleoindian, Ontario
While the Lonely Mingle with Circumstance
Emmanuel Levinas’ philosophy focuses on the idea that no human subject exists outside of their relationship to other people. Each of us holds a profound degree of responsibility to and for all others. Since responsibility is fundamental to human (co)existence, it does not impede on freedom but proves that the sovereign individual is a dangerous myth: any philosophical, political or economic system which places us in antagonism is inherently violent and arguably fallacious. Many instances of injustice and violence can be attributed to advances in technological rationality and other forces of modern egoism with historical roots. By forwarding a somewhat politicized interpretation of Totality and Infinity and drawing on Jacques Derrida’s landmark reading of Levinas, this thesis explores the implications of Levinas’ thought for modern politics and the potential of Levinasian ethics as a remedy for both the alienation of the modern subject and the continued justification of oppression. Author Keywords: Ethics, Levinas, Other, Relation, Responsibility, Subjectivity
