Changes in the Representations of Women from the 1980s Turkish Cinema to New Turkish Cinema
The thesis examines the changes in the representations of women in Turkish cinema from the 1980s through the 2000s in terms of semiotic codes. To demonstrate the shifts of the representations of women over three decades, four films directed by two representative filmmakers of the 1980s and the 2000s are analyzed within the context of gender codes: A Sip of Love (Atıf Yılmaz/1984), The Night, Angel and Our Gang (Atıf Yılmaz/1994), The Third Page (Zeki Demirkubuz/1999) and Envy (Zeki Demirkubuz/2009). Using gender as code in deconstructing women’s characteristics and their representations in the films, the research highlights the structural image of women in the semiotic sense. The stereotypical representations in Turkish cinema question social norms, patriarchy, and Islamic norms in Turkey.

Changes in Forms of Uranium in Anoxic Lake Sediments and Porewaters Near an Abandoned Uranium Mine, Bancroft, Ontario
Soluble uranium (U) has been observed continuously in the porewaters of Bentley Lake, a lake with semi-permanent anoxic sediments, despite the fact that reduced U(IV) is known to be insoluble. To be able to predict the fate and mobility of U that has been deposited in lake sediments, it is very important to understand the factors that determine soluble uranium in anoxic environments. Understanding soluble U species is crucial for predicting its behavior in natural systems as well as for the development of U remediation schemes. To explore the factors affecting soluble U in natural environments, anoxic lake sediments and porewaters were tested using two analytic methods, ICP-MS and ESI-HR-MS. Reduced uranium (U(IV)) can be precipitated as U(IV)-NdF3. Using this method revealed that most of the uranium in porewater is not able to be co-precipitated with NdF3. In addition, UO2+ was found using ESI-HR-MS, showing uranyl ions exist in reduced porewater. However, the UO2+ might be attached to some organic groups rather than present as free ions. Seasonal variation and air exposure experiments on the mobility of U between sediments and porewater were observed to test for changes of the redox state of U as a function of sample collection and storage. The results of this study will contribute to better remediation strategies for U tailings and will help U mining operations in the future. Author Keywords:
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.

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.

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.

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.

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.

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.

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.

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
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.

Calcium in the Muskoka River Watershed- Patterns, trends, the potential impact of forest harvesting and steps toward an ecosystem approach to mitigation
Decreasing lake calcium (Ca) concentration, in lakes located in base poor catchments of the Muskoka River Watershed (MRW) in south-central Ontario, is a well- established acid-rain driven legacy effect threatening the health and integrity of aquatic ecosystems that can be compounded by additional Ca removals through forest harvesting. The objectives of this thesis were to assess patterns and temporal trends in key water chemistry parameters for a set of lakes in forested catchments in the MRW in south- central Ontario, to predict the pre-industrial steady state lake Ca concentration and the potential impact of harvesting on lake Ca levels in lakes located in managed MRW Crown forests, and to assess potential effects of various mitigation strategies in Ca depleted managed forests. Mean lake Ca (mg L-1) in 104 lakes across the MRW have decreased by 30% since the 1980's with the rate of decrease slowing over time. Mean Lake SO4 (mg L-1), and Mg (mg L-1) concentration also decreased significantly with time (37% and 29%, respectively) again with a declining rate of decrease, while mean lake pH and DOC increased significantly between the 1980's and the 1990's (16% and 12%, respectively) but exhibited no significant pattern after that. Principal components and GIS spatial analyses of 75 lakes with data from 2011 or 2012 water seasons suggested that smaller lakes, at higher elevation in smaller catchments with higher runoff and minimally impacted by the influence of roads and agriculture are associated with lower Ca concentrations and thus are the lakes at risk of amplified Ca depletion from forest harvesting. Spatial analyses of harvested catchments indicated that, under the proposed 10 year land forest management cut volumes, 38% of 364 lakes in the MRW will fall below the critical 1 mg L-1 Ca threshold compared with 8% in the absence of future harvesting. With respect to potential mitigation measures, soil pH and foliar Ca were indicated by meta-analysis to be more responsive to lime addition studies while soil base saturation and tree growth appeared more responsive to wood-ash addition. Future research should address the spatial extent of lakes at risk and identify when critical levels will be reached under harvesting regimes. Further investigation into the use of Ca-addition as a tool for managing the cumulative effects of past, present and future stressors is recommended. Author Keywords: calcium, harvesting, lakes, lime, Muskoka River Watershed, wood-ash
