ROOSTING SELECTION BEHAVIOUR OF THE EASTERN WILD TURKEY AT ITS NORTHERN RANGE EDGE
As wild turkeys (Meleagris gallopavo silvestris) move farther north, informed management decisions are critical to support the sustainability of this reintroduced species. We tracked roost tree selection and patterns of the network of roost trees, for wild turkeys, over 2 years in Peterborough, ON, using GPS and VHF transmitters. Wild turkeys showed preference for taller and larger roost trees, with winter roosts closer to buildings. The roost network exhibited a scale-free network, meaning certain roosts served as hubs, while other roosts were less frequently used. The fine scale results suggest that roost trees are selected for predator avoidance, and that selection changes with the season, probably because of its influence on foraging ability. At a larger scale, winter roosts were chosen for their proximity to supplemental food sources. These findings demonstrate the dependence of wild turkeys on humans and the supplemental sources we unintentionally provide. Author Keywords:
Racism in Argentina and the Blackness Problem. The Change in Perception of Afro-Descendants in Buenos Aires and the New Dimensions of Blackness in Argentina (1880-1930)
This thesis examines racism in Argentina between 1880 and 1930. The governing elite's efforts to whiten the Argentine population at the end of the nineteenth century led to the erasure and discrimination of anyone who did not have Caucasian features: Afro-descendants, mulattos, mestizos, and creoles. However, in the 1930s, whitening policies proved to have limited success. On the one hand, Afro-descendants were praised by the middle and lower classes of Buenos Aires; on the other hand, the Great Depression's effects made it clear that the Argentine population was made up of an ethnic mixture that had much darker skin tones than the whitening elite preferred. This work will show how the impact of the 1930s global crisis, as well as the enthusiasm for Afro-descendants, reinforced the racism that still existed, and will demonstrate that blackness became more than a racial but also a class connotation.

Radiocarbon Analysis of the Middle to Late Woodland Transition in Southern Ontario
The goal of the thesis is to establish the temporal patterning of the cultural complexes of the Middle to Late Woodland periods in Ontario. To do so I examine the statistical shape and phase boundaries of samples of radiocarbon dates associated with the Princess Point, Sandbanks, Glen Meyer, and Pickering archaeological complexes. The radiocarbon dates used for this thesis were collected through published sources, grey literature, and resources such as the Canadian Archaeological Radiocarbon Database. Each date was put through a data hygiene process and those deemed acceptable were merged into Summed Probability Distributions (SPDs) and further analysed through the r-carbon and OxCal packages. Bayesian statistics were used to estimate the start and end dates per complex, Shapiro-Wilks tests were used to examine the legitimacy of cultural entities, and the amount of geographic, and chronological overlap was determined by randomly sampling between the compared datasets to determine an acceptable threshold of randomness. Results indicate that the Princess Point complex does not meet the requirements of a culturally homogeneous archaeological cultural group. There is no difference in the Glen Meyer and Pickering radiocarbon patterns, which supports combining them into a single cultural designation. It was impossible to evaluate the Sandbanks complex due to a lack of radiocarbon data, although overall it seems to agree with the current understanding of the complex.

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.

Range-Based Component Models for Conditional Volatility and Dynamic Correlations
Volatility modelling is an important task in the financial markets. This paper first evaluates the range-based DCC-CARR model of Chou et al. (2009) in modelling larger systems of assets, vis-à-vis the traditional return-based DCC-GARCH. Extending Colacito, Engle and Ghysels (2011), range-based volatility specifications are then employed in the first-stage of DCC-MIDAS conditional covariance estimation, including the CARR model of Chou et al. (2005). A range-based analog to the GARCH-MIDAS model of Engle, Ghysels and Sohn (2013) is also proposed and tested - which decomposes volatility into short- and long-run components and corrects for microstructure biases inherent to high-frequency price-range data. Estimator forecasts are evaluated and compared in a minimum-variance portfolio allocation experiment following the methodology of Engle and Colacito (2006). Some consistent inferences are drawn from the results, supporting the models proposed here as empirically relevant alternatives. Range-based DCC-MIDAS estimates produce efficiency gains over DCC-CARR which increase with portfolio size. Author Keywords: asset allocation, DCC MIDAS, dynamic correlations, forecasting, portfolio risk management, volatility
Re-Living the Residential School Experience
The residential school legacy is one of the darkest chapters in Canadian history. From the mid-1850s to 1996, thousands of Aboriginal children were taken from their homelands and placed in residential schools. Taken against their will, many dreaded attending these schools. Some attended for as long as ten to fifteen years, only to be strangers in their own communities upon their return. In the past thirty years, survivors began disclosing the loneliness, confusion, fear, punishment and humiliation they suffered within these institutions, and also reported traumatic incidents of sexual, physical or emotional abuse. These childhood traumas still haunt them today. This dissertation examines the four compensation processes (Litigation, Alternative Dispute Resolution, Independent Assessment Process and the Common Experience Process) used by survivors to determine whether the compensation payments made to them assisted in reconciliation of their residential school experience. To complete an analysis of the processes, twenty-four residential school survivors from Ontario, Manitoba and British Columbia were interviewed about their experiences with one or more of the compensation processes. The study begins with a historical overview of the residential school legacy and continues with the residential school healing movement that initiated and finalized a negotiated settlement agreement for all living survivors. This dissertation provides a unique perspective to the residential school legacy by using a cultural framework, Anishinabe teachings and concepts to share the voices of residential school survivors. The pivotal Anishinabe teaching within this study comes from The Seventh Fire Prophecy. This prophecy states that: “If the New People will remain strong in their quest, the Waterdrum of the Midewiwin Lodge will again sound its voice.” In this dissertation the residential school survivors are the New People. As the dissertation unfolds the author utilizes various Anishinabe concepts to illustrate how the compensation processes failed to assist the New People to reconcile with their residential school experience. This study presents a medicine wheel understanding of reconciliation and the Residential School Legacy. It concludes with an important message to the second and third generation survivors to continue the reconciliatory efforts that the New People introduced. It is crucial that the children and grandchildren of the New People begin the reconciliation process not only for themselves but for the next seven generations.

Real-space renormalization group approach to the Anderson model
Many of the most interesting electronic behaviours currently being studied are associated with strong correlations. In addition, many of these materials are disordered either intrinsically or due to doping. Solving interacting systems exactly is extremely computationally expensive, and approximate techniques developed for strongly correlated systems are not easily adapted to include disorder. As a non-interacting disordered model, it makes sense to consider the Anderson model as a first step in developing an approximate method of solution to the interacting and disordered Anderson-Hubbard model. Our renormalization group (RG) approach is modeled on that proposed by Johri and Bhatt [23]. We found an error in their work which we have corrected in our procedure. After testing the execution of the RG, we benchmarked the density of states and inverse participation ratio results against exact diagonalization. Our approach is significantly faster than exact diagonalization and is most accurate in the limit of strong disorder. Author Keywords: disorder, localization, real-space renormalization, strong correlations
Reassessing Bioarchaeological Sex Determination and Research into Gender at the Early Anglo-Saxon Worthy Park Burial Ground Round in Hampshire, England
When bioarchaeologists investigate ancient gender identity, they typically place skeletal remains into one of six sex assessment categories: male, female, possible/probable male, possible/probable female, ambiguous, and indeterminate. However, the study samples are often reduced to male and female reproducing a male/female gender and sex binary prevalent in the "Western" cultural milieu and bioarchaeology when inferences are made about gender and sex in the past. In order to allow for the existence of non-binary cultural genders and biological sexes, this thesis: 1) demonstrates the multitude of ethnographic, ethnohistoric, historic, and medical evidence relating to non-binary sex and gender expression; 2) tests a method inspired by Whelan (1991) that looks at gender as an identity not fully inspired by biological sex; 3) keeps all sex assessment categories used by bioarchaeologists separate in analysis and interpretation; and 4) analyses patterns relating to all available material culture and biological attributes in a mortuary sample to investigate gender identity. This thesis used the Early Anglo-Saxon (470-600 AD) burial ground at Worthy Park in Hampshire to achieve these objectives. This thesis found that when examining all sex assessment categories among all mortuary variables, only the male sex was clearly defined by its mortuary assemblage. This suggests a one gender structure corresponding to linguistic evidence for one gender in Old English.

Reconceptualising the Heteronormative Curriculum Through Autobiographical Methodology - A Study of Heteronormativity within Ontario Ministry of Education Curriculum Documents
This thesis is about the negative impacts on queer identities caused by the lack of diversity related to sexual orientation within Ontario Ministry of Education curriculum documents, both at the elementary and secondary level. Curriculum documents as well as policy documents are analysed and compared in order to address the lack of diverse sexual orientation representation within Ontario’s education system. The study is guided by the question: “who benefits from the current representations of sexual orientation in the curriculum?” This conceptual study advances autobiographical methodology and the concept of Currere in relation to queer theory that allows researchers to analyse their educational experiences throughout the course of their lives and then become agents of social change. The results of my personal curriculum analysis have shown that curriculum documents lack diverse sexual orientation representation and that this has negative impacts how LGBQQ people identify and on the course of their lives.

Reconceptualizing Immigration in Canada
This thesis challenges the contemporary framework of immigration in Canada. Despite Canada’s effort to promote cultural diversity and multicultural citizenship, immigration policy in the last decade has moved towards a model of cultural assimilation. The recent Bill—Strengthening Canadian Citizenship Act—devalues non-European cultures and hinders the successful integration for new immigrants. The problem of contemporary immigration in Canada lies in the narrow and exclusive understanding of immigration. That is, the current immigration framework is rooted in Eurocentrism, which draws exclusively from the economic and cultural values of the West. The Eurocentric understanding of migration not only hinders the successful integration for new immigrants, but it also hinders economic growth and weakens the social cohesion of Canada. For this reason, this thesis offers an alternative framework for understanding immigration. I focus on Chinese migration in Canada and take an interdisciplinary and a conceptual approach in order to present an inclusive understanding of Chinese migration. In particular, I apply the idea of "connected histories" to the context of immigration, and I demonstrate that immigration is a complex and interconnected phenomenon which cannot be reduced to the narratives of economics and ‘Canadian values.’ Instead, immigration should be understood as a process of transnational interactions because it not only allows us to understand benefits that transnational interactions would bring to immigrants, their country of origin and Canada, but it also recognizes different values and the agency of immigrants.

Reconceptualizing a Post-Secondary Program for Students with Intellectual Disabilities
The number of post-secondary programs for students with intellectual disabilities has been on the rise since the early 1990’s (Plotner & Marshall, 2015). However, research focused on student experiences within these programs has been predominantly from faculty, mainstream students and parent’s perspectives without accounting for what the students themselves are experiencing. This thesis however utilizes critical narrative inquiry as a methodology to listen the stories of students with disabilities, in conjunction with the researcher’s personal and professional experiences to reconceptualize the CICE program at Fleming College in Peterborough Ontario in order to provide students with more responsive and inclusive educational experiences. Six themes emerged from interviews conducted in the research: friendship/social opportunities, career/goals, supports, barriers/challenges, independence/freedom and finally identity/inclusion. A critical exploration of these themes is provided to develop programmatic, college and community level changes that forward a reconceptualized view of post-secondary education for adults with disabilities. Author Keywords: Critical disability theory, Critical narrative inquiry, Post-secondary programs for students with disabilities, Student voice
Reconciliation as Relationship
In 2015, Canada’s Truth and Reconciliation Commission called upon Canadians to reconcile relationships between Settlers and Indigenous peoples in Canada. Education for reconciliation is one important element of this process. However, critical questions arise when education is undertaken by and for Settlers such as myself: Are our undertakings actually fostering reconciliation? According to whom? Drawing from reconciliation theory and decolonizing Indigenous methodologies, a reconciliation methodology is created to consider this question in the context of three reconciliation workshops for Settlers. Indigenous perspectives and pedagogies are prioritized. The emerging understandings of reconciliation as relationship and relationship as pedagogy reframe some prevailing Settler thinking about reconciliation, unmask latent assumptions linked to the colonial habits of mind and affirm the need for personal responsibility in the reconciliation relationship. The Indigenous norm of learning in-relation is found to be a powerful experience for Settlers participants offering valuable insights for reconciliation education in Canada. Author Keywords: decolonizing, education, Indigenous, relationship, Settler, Truth and Reconciliation
