Calming Chaos in the Classroom
Physical activity and classroom design changes are beneficial means to reduce stress, and enhance well-being. Results across some studies however, are mixed. Shanker Self-Reg™ supports the use of physical equipment and design as a means of managing arousal and tension levels. Previous research lacks rich description of educators’ understanding of equipment and design, Self-Reg, and how this understanding affects the way it is implemented. In the current study, educators’ understanding of Self-Reg, how this understanding influenced educators’ approach to the school environment, and if one workshop was enough to inspire individuals to adopt a Self-Reg approach were explored using thematic analysis. Participants included educators from schools with beginner and intermediate-level experience in Self-Reg. The analysis produced eight themes and 8 sub-themes. Participants’ knowledge of Self-Reg influenced their approach to their environments. Although one workshop may have inspired interest in the framework, it was not enough to shift educators’ current practice.

Calving site selection and fidelity in a restored elk (Cervus elaphus) herd in Bancroft, Ontario, Canada
ABSTRACT Calving site selection and fidelity in a restored elk (Cervus elaphus) herd in Bancroft Ontario, Canada. Michael R. Allan Parturition site selection by ungulates is believed to be influenced by forage abundance and concealment from predators. In 2011 and 2012, I used vaginal implant transmitters and movements to identify calving sites for 23 GPS collared elk (Cervus elaphus) from a restored herd. I tested the hypothesis that maternal elk used sites with higher forage and denser concealment compared to pre-calving sites at micro and macrohabitat levels. I detected no significant microhabitat differences from direct measurements of vegetation. At the macrohabitat scale, based on proximity of landcover classes, mean distances to hardwood forests was significantly less for calving (153 m) than pre-calving sites (198 m). Site fidelity is hypothesized to offer security in terms of familiarity to an area. I tested the hypothesis that females demonstrated fidelity to their previous year's location during pre-partum, parturition, post partum, breeding and winter periods. Elk were more philopatric during parturition and post partum than during breeding. Compared to winter elk were more philopatric during pre-partum, parturition and post-partum periods. Expressed as distance between consecutive-year calving locations, site fidelity varied with 27% of females exhibiting high (<1 km), 18% moderate and 55% (>2.9 km) low fidelity. I measured nearest-neighbour distances at calving time, exploring the hypothesis that females distance themselves from conspecifics. Elk increased the average distances to collared conspecifics during parturition; however, sample sizes were small. This strategy might influence calving site selection. Rapid movement prior to parturition, low site fidelity and spacing-out of females during parturition appear to be strategies to minimize predator risk and detection. Little evidence of selection for vegetation structure suggests this may not be limiting to these elk. Author Keywords: calving, elk, fidelity, movement, parturition, selection
Can Shared Platforms Build Sustainability in the Non-profit Sector? Comparing Practitioner Perceptions of Organizational Experience in Non-profit Organizations and Platform Projects
This thesis explores practitioner perceptions of operational and structural experiences of non-profit organizations (NPO) and platform projects (PP) to develop an understanding of how a shared platform governance model can build resiliency and sustainability in non-profit organizations. The objectives of this research are to 1) develop an understanding of NPO and PP operational and structural experiences based on qualitative interviews with practitioners; 2) analyze how a PP model can address challenges facing the NPO sector; and 3) based on a thorough analysis of current literature and research findings, recommend a model that addresses these challenges and builds sustainability in NPOs. A grounded inductive approach was used to identify a thematic narrative. The process was iterative, working between existing literature and interview data. Interviews with eight NPO practitioners and eight PP practitioners revealed four narrative theme areas: Financial, Funder, Organizational, and Emotional Tone. The results document several ways a PP model can provide opportunities to address the perceived funder and organizational challenges of small NPOs.

Canadian Refugee Policy
This dissertation is an inquiry into the politics of the frame in Canadian refugee policy. It is focused on "framing," thereby taking up the stance of critical policy studies while pressing the contribution of Donald Schön and Martin Rein in a critical and politically inflected direction. The dissertation unfolds as a political history of Canadian refugee policy that provides a "contextual mapping," relevant to both inquiry and action in regard to the framing of refugees. The main argument is that twentieth- and twenty-first- century refugee policy in Canada is a story of three shifting meta-frames: beginning with humanitarianism (in the inter-War years and the post-World War II period); shifting to neo-humanitarianism (beginning in the late 1970s, in connection with the rise of neoliberalism); then shifting again (beginning in the 1990s) to securitization. The concept of a meta-frame here is analogous to that of a "metacultural frame" in Schön and Rein, but accents political rather than cultural dimensions. This concept is developed in a manner suitable to a political history by illustrating how meta-frames both become stable and change. With humanitarianism, the refugee was typically portrayed in ambivalent terms - both deserving of and entitled to protection, while also posing a burden for the national interest. In the context of neo-humanitarianism, this ambivalence began to wane, and the refugee was more typically portrayed as a potential criminal. With securitization, especially as it has become entrenched and intensified, the refugee has been more typically portrayed as a potential terrorist. The analysis includes a focus on the particular importance of ambivalence and contingency in the politics of the frame. Securitization has become so deeply entrenched since September 11, 2001 that it appears virtually fixed in place. However, it may still become possible in moments of contingency for refugee advocates to destabilize the securitization meta-frame and help shift the framing of refugees into a more hospitable register.

Canid Predation of Domestic Sheep (Ovis aries) on Ontario Farms
Livestock predation by wild predators is a frequent and complicated issue, often cited as a significant factor in the decline of livestock production and justification for killing predators. Coyotes (Canis latrans) are the primary predators of sheep in Ontario. Some farms appear to be more susceptible to predation than others, despite the use of mitigation techniques. I explored land cover in the vicinity of farms as a potential influence on the level of predation, as coyote abundance and wild prey are correlated with certain habitat types. Using model competition, I show that landscape explains little variation in predation levels over all farms, but can explain 27% of variation in the percent of a flock killed. Total forest edge habitat and distance between forest patches were both positively associated with losses, suggesting a reduction in forest cover surrounding a farm puts the flock at greater risk. In addition, I tested four disruptive deterrents for effectiveness at protecting flocks. A matched-pairs analysis did not show a statistically significant benefit of these non-lethal mitigation tools.

Canoeing through Resurgence
Anishinabai are jiimaan people. The traditional building of wiigwaas jiimaan is a part of a resurgence project that is restoring and maintaining cultural connection to our homelands, the water, and community members. An approach to cultural resurgence, such as the wiigwaas jiimaan, is an attempt to generate a better connection to our homeland, self- determination, and forms of healing within a cultural context. Through diverse research methodologies, this project will open new doors to cultural resurgence methods, Indigenous knowledge and the story telling of the wiigwaas jiimaan. Over the summer of 2018, I built a wiigwaas jiimaan in my home community of Temagami First Nation. It is from this experience that this research shaped. Through the approach of storytelling to my reflective notes, while incorporating an Indigenous knowledge and resurgence methodology. It is important that when you are reading this, that you keep an open mind, sit comfortably and enjoy the interweaving of story and research. The thesis creates a better understanding of resurgence practices, the history of the Teme- Augama Anishinabai, my story and experience with the wiigwaas jiimaan, and the rebuilding of my community through this cultural initiative. Moving forward I hope that this research continues and evolves to other communities, who look for healing and cultural reclaiming through the land. Miigwetch.

Capital Ratios and Liquidity Creation
Using quarterly data from the six largest Canadian banks, we investigate the relationship between regulatory capital ratio and on-balance sheet liquidity created in the Canadian economy by “Big Six”. We find a significant positive relationship between Tier 1 capital ratio and on-balance sheet liquidity creation for Canadian big six banks, implying that large banks in Canada favor risks and rely on capital to fund illiquid assets. In contrast, for smaller banks, the relationship is significantly negative. Our results are robust to dynamic panel regression using 2-Step GMM, two exogenous shocks - COVID-19 crisis and the Global Financial Crisis (2007-2009), mergers & acquisitions activities in the banking industry, and core deposits financing. The COVID-19 pandemic and core deposits adversely impact the Tier 1 capital ratio’s relationship with on-balance-sheet liquidity creation, while the global financial crisis (2007-2009) effect on the association is insignificant.

Carbon Exchange along a Natural Gradient of Deciduous Shrub Coverage in the Low-Arctic
Arctic terrestrial ecosystems have experienced substantial structural and compositional changes in response to warming climate in recent decades, especially the expansion of shrub species in Arctic tundra. Climatic and vegetation changes could feedback to the global climate by changing the carbon balance of Arctic tundra. The objective of this thesis was to investigate the influence of increased shrub coverage on carbon exchange processes between atmosphere and the Arctic tundra ecosystem. In this study a space-for-time substitution was used, referred to as a shrub expansion “chronosequence”, with three sites along a natural gradient of deciduous shrub coverage in the Canadian low Arctic. Leaf-level photosynthetic capacity (Amax) of dominating birch shrub Betula glandulosa (Michx.) was significantly higher (P<0.05) at the site where shrubs were more abundant and taller than at the other sites. For all sites, mean Amax in 2014 was significantly lower than in 2013, in part potentially due to differences in precipitation distribution. Bulk soil respiration (RS) rate was significantly higher (P<0.05) at the site with more shrubs compared with the other sites. The differences in RS across sites appeared to be driven by differences in soil physiochemical properties, such as soil nitrogen and soil bulk density rather than soil microclimate factors (e.g. soil temperature, moisture). The three sites were either annual CO2 sources (NEP<0) to the atmosphere or CO2 neutral, with strongest annual CO2 sources (-44.1±7.0 g C m-2) at the site with most shrubs. Overall this study suggests that shrubs tundra carbon balance will change with shrub expansion and that shrub ecosystems in the Arctic currently act as annual carbon sources or neutral to the atmospheric CO2 and further shrub expansion might strengthen the CO2 emissions, causing a positive feedback to the warming climate.

Carbon and Nitrogen Isotope Changes in Streams along an Agricultural Gradient
Nitrogen is a major constituent of agricultural fertilizers, and nitrogen inputs to stream water via runoff and groundwater lead to a variety of negative environmental impacts. In order to quantify the movement of nitrogen through aquatic food webs, fourteen streams with varying land uses across South-Central Ontario were sampled for two species of fish, freshwater mussels, and water for measurement of isotope ratios of δ15N and δ13C. I found that nitrogen isotopes in fish, water, and mussels were related to the percentage of riparian monoculture, and that carbon isotopes were unrelated to monoculture. Though all species were enriched as monoculture increased, the rate of δ15N enrichment as monoculture increased did not vary between species. This study has improved our understanding of how monoculture affects nutrient enrichment in stream food webs, and assesses the validity of using nitrogen isotopes to measure trophic positions of aquatic organisms across an environmental gradient.

Cartoons Ain't Human
Why show things that aren’t people acting like people? In the field of animation, it’s a surprisingly big “why?”, because it’s a “why?” that doesn’t lead to any sort of doctrine of ontology, of inevitability, of manifest destiny, or of anything like that. But it does lead to another “why?”—“why did anthropomorphic depictions of animals and non-human entities come to define an entire era of American short-form animation?” When we think about ‘classic era’ cartoon shorts, the first names that come to mind are likely to be those of anthropomorphic animal characters—Mickey Mouse, Bugs Bunny, and a list of others so numerous that any machine Wile E. Coyote tried to build to count them all would probably explode. This can make us lose sight of the fact that human characters had their place as well in these films: Bugs and Daffy regularly tangled with Elmer Fudd; the studio that made cartoon stars of Betty Boop and Popeye produced no famous animal characters at all in its heyday. And yet, it’s the animals that steal the show in the animated shorts produced by major studios in America from the 1920s through the 1960s. Part of their appeal lies in the fact that they were useful and recognizable substitutes for humans. Without making things too ‘personal’ for the audience, they could be used to examine and deconstruct social practices in the full-speed-ahead period that took America from World War I to the war in Vietnam. Animals weren’t the only ones to get a full-on anthropomorphic treatment in these shorts. Machines and other artefacts came to life and became sites of interrogation for contemporary anxieties about the twentieth century’s ever-expanding technological infrastructure; parts of the natural world, from plant life to the weather, acted with minds of their own in ways that harken back to the earliest animistic folk beliefs. No matter when or how it’s being used, anthropomorphism in animation is a device for answering, not one big “why?”, but a lot of little “why?”s. What you’re about to read is an exploration of a few of those little “why?”s. Author Keywords: America, Animation, Anthropomorphism, Cartoons, Deconstruction, Popular Culture
Cemeteries and Hunter-Gatherer Land-Use Patterns
The principle aim of this thesis is to evaluate the applicability of the Goldstein/Kelly hypothesis, which proposes that hunter-gatherer cemeteries emerge as a product of resource competition, and function to confirm and maintain ancestral ties to critical resources. My evaluation centres on a case study of the earliest known cemeteries of the middle Trent Valley, Ontario. To determine whether these predictions are true, I investigated the ecological context of local wetland-based foraging, and undertook a locational analysis to determine if the placement of cemeteries correlates with environmental characteristics that reflect the presence of valuable resources that are unique to these locations. The analysis reveals that ancient cemeteries in the middle Trent Valley were located near seasonal riparian wetlands, possibly to secure wild rice and the variety of fauna it attracts. Through the integration of paleoecological, archaeological, and ethnographic information for the region, this research finds support for the Goldstein/Kelly hypothesis.

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.
