Bank Swallow (Riparia riparia) Breeding in Aggregate Pits and Natural Habitats
I examined Bank Swallow (Riparia riparia) colony persistence and occupancy, in lakeshore, river and man-made aggregate pit habitat. Habitat persistence was highest on the lakeshore and lowest in aggregate pits, likely due to annual removal and relocation of aggregate resources. Bank Swallow colonies in aggregate pit sites were more likely to persist if a colony was larger or if burrows were located higher on the nesting face. I also compared nest productivity and health factors of Bank Swallows in lakeshore and aggregate pit habitats. While clutch size was the same in both habitat types, the number of fledglings from successfully hatched nests was significantly higher in aggregate pit sites than from lakeshore sites. Mass of fledgling Bank Swallows did not differ significantly between habitat types, however mass of adults from aggregate pits decreased significantly over the nesting season. Parasite loads on fledgling Bank Swallows were significantly lower in aggregate pits than in lakeshore sites. According to these indicators, aggregate pits appear to provide equivalent or higher quality habitat for Bank Swallows than the natural lakeshore sites, making them adequate and potentially key for this species’ recovery. Aggregate pit operators can manage for swallows by (1) creating longer, taller faces to attract birds and decrease predation, and (2) supplementing their habitat with water sources to encourage food availability.

Barriers and Facilitators to Indigenous Knowledge Incorporation in Policy Making
The inclusion and application of Indigenous Knowledge (IK) has become a central and often demanded element of policy making involving Indigenous peoples. However, there are very few examples that exist in the literature and elsewhere that show how IK can be effectively integrated into decisions, policies, and programs. In response to these challenges, this research explored what processes are used to incorporate IK into policy and their effectiveness through the development of a framework that sought to identify critical factors related to IK inclusion. The framework was then applied to evaluate IK incorporation opportunities in the Nunatsiavut case, focusing on the development of the Nunatsiavut Government's Environmental Protection Act. The case study analysis was used to test and provide adaptations to the initial framework. This research identifies the importance of governance structures and processes, community participation and engagement approaches, and IK research and support programming in enhancing opportunities for IK to be integrated and reflected in policy outcomes. The Nunatsiavut case largely supported, but in some cases challenged critical factors of IK incorporation identified in the framework. The findings of this study are valuable for policy and decision makers (both Indigenous and non-Indigenous) regarding approaches and programs that can assist and support IK inclusion into policy processes and decisions.

Battle of Maldon
The Battle of Maldon: A Medieval Screenplay History and Heroism in the Cinematic Adaptation of an Old English Poem The Battle of Maldon is an artistic representation of a historical event whose style lends itself to being adapted into a screenplay. This project examines how the poem presents a recent event in an epic heroic style, mixing history with legend, and how the heroism of the men in the poem is celebrated. These explorations lead to the creation of a screenplay which imitates the ways that the poet combines fact and fiction and situates the screenplay within the larger realm of medieval film. Author Keywords: Anglo-Saxon history, Byrhtnoth, film, heroism, Maldon, The Battle of Maldon
Becoming Hybrid
Institutional military strategists are developing theories of asymmetric and unconventional warfare that complicate the notion of strategic agency, the idea that military action emanates from a coherent agential source or subjectivity. This thesis attempts to push the conceptual trajectories of the theories of Hybrid War, Unrestricted War and Onto-power towards an even more radical complication of the notion of strategy - towards an ecological understanding of war as an unwinnable, self-perpetuating process. Recent geopolitical events are meticulously examined, as are institutional doctrinal and theoretical frameworks that stop just short of imploding the conventional agential notion of strategy. Insights from the work of Gilles Deleuze and Felix Guattari, as well as Brian Massumi, particularly the concepts of multiplicity, assemblage, and ontopower, are employed in the thesis, which is itself a “heterogeneous assemblage” of elements ranging from Israeli war theory and Chinese military doctrine to etymology and post-structuralist philosophy. Author Keywords: Agency, Assemblage, Deleuze, Hybrid warfare, Multiplicity, Strategy
Becoming and Destiny in Deleuze and Guattari
This thesis is an investigation of the theme of freedom in the work of Gilles Deleuze and Felix Guattari. Chapter One investigates Deleuze and Guattari’s concept of becoming as it is articulated in their book A Thousand Plateaus, and seeks to resolve a problem related to their shifting descriptions of the role of agency in the process of becoming, at times described as voluntary, and at other times described as involuntary. We conclude that chapter with a defense of the claim that their shifting descriptions are unproblematic and are, in fact, attempts to illustrate the paradoxical experience of becoming. Chapter Two investigates Deleuze’s earlier text, The Logic of Sense, and attempts to make sense of his use of the term destiny. Our conclusion in that chapter is that destiny is neither necessity, pure self-authorship, nor passive resignation, but rather consists of a mixture of activity and passivity, willfulness and chance.

Bio-based Polymers from Epoxidized Vegetable Oils Modified by Metathesis
The epoxides of oligomeric self-metathesized soybean oil (MSBO) and cross-metathesized palm oil (PMTAG) and canola oil (CMTAG) containing terminal double bonds were used to produce nonisocyanate polyurethanes (NIPUs) as well as anhydride, amine and thiol-cured epoxies. The synthesized NIPUs displayed metal adhesive properties for CMTAG and MSBO with MSBO being favoured probably due to its plasticizing nature as opposed to CMTAG. The relationship was reversed for the anhydride curing reaction where it was found that CMTAG, due to its lower degree of plasticizing content from the reduced dangling chains, produced higher tensile strengths than MSBO. Both MSBO and CMTAG led to fully cured amine and thiol products that were sticky gels, which prevented physical analyzses of their expected solidified products. PMTAG, due to its low number of reactive groups, was not suitable for the synthesis of these polymers.

Biology and Management of Stratiotes Aloides in the Trent River, Ontario
Invasive aquatic plants can create negative ecological, economic and social impacts when they displace local vegetation, interfere with shipping and navigation and inhibit water-based recreational activities. In 2008, the first North American occurrence of the invasive plant Stratiotes aloides (Water soldier) was identified in the Trent River, Ontario. This research measured offset photosynthesis and turion germination to determine the light compensation point (5.2-5.4m) and maximum depth of colonization (4-6m) for S. aloides propagules using in situ incubations and controlled growth experiments. The effects of spring and fall chemical (Diquat) and physical (hand raking) treatments on S. aloides biomass, local macrophyte recovery and community dynamics in the Trent River were also measured. The target of a 75% minimum reduction in S. aloides biomass was not attained using any of the treatment methods and no perceivable recovery of the local plant community was observed. Significant S. aloides regrowth was recorded for both treatment methods regardless of application timing. Author Keywords: herbicide, invasive species, macrophyte, photosynthesis, propagule
Bioremoval of copper and nickel on living and non-living Eugelna gracilis
This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems results indicate that the sorption reaction occurs quickly (<30 min) in both Cu (II) and Ni (II) mono-metallic systems and adsorption follows a pseudo-second order kinetics model for both metals. Sorption capacity and intensity was greater for Cu than Ni (p < 0.05) and were described by the Freundlich model. In bi-metallic systems sorption of both metals appears equivalent. In non-living systems sorption occurred quickly (10-30 min) and both Cu and Ni equilibrium uptake increased with a concurrent increase of initial metal concentrations. The pseudo-first-order model was applied to the kinetic data and the Langmuir and Freundlich models effectively described single-metal systems. The biosorption capacity of Cu (II) and) was 3x times greater than that of Ni (II). Sorption of one metal in the presence of relatively high concentrations of the other metal was supressed. Generally, it was found that living Euglena remove Cu and Ni more efficiently than non-living Euglena biomass in both mono- and bi-metallic systems. It is anticipated that this work should contribute to the identification of baseline uptake parameters and capacities for Cu and Ni by Euglena as well as to the increasing amount of research investigating sustainable bioremediation. Author Keywords: accumulation, biosorption, Cu, Euglena gracilis, kinetics, Ni
Bringing Knowledges Together
The natural world and environmental issues present critical points of convergence between Indigenous and non-Indigenous people and their knowledge systems. This qualitative study engaged with 18 Indigenous and non-Indigenous environmental practitioners in interview conversations to explore their experiences in cross-cultural environmental collaborations. The research undertakes a complexity theory approach to answer the following research questions: 1.a) What skills, values, knowledges and approaches do environmental practitioners need to enable Western and Indigenous knowledge systems to come together in addressing environmental challenges? 1. b) What does effectiveness and/or success look like in cross-cultural environmental collaboration? 2. How can post-secondary and professional development educational programs impart the skills, values, knowledges and approaches that their students need to effectively engage in work that brings together Indigenous and non-Indigenous people and their knowledge systems in addressing environmental challenges? This study applied multiple lenses to analyze and interpret the data. The author’s own reflections as both a practitioner and researcher working and teaching in crosscultural environmental contexts were a central component of the study. Through this analysis a set of skills, values, knowledges, approaches, attributes, and roles emerged. The findings reaffirm the importance of respect, relationship, responsibility, and reciprocity as central values in Indigenous praxis and identify additional values. The application of a critical theory lens illuminated that subtle racism and microaggressions influence environmental collaboration between Indigenous and non-Indigenous people. The study proposes a curriculum and program design for post-secondary and professional development contexts, that draws upon multiple pedagogies to prepare learners to work cross-culturally in respectful ways. These findings are relevant to environmental practitioners currently working in the field and contribute to a further articulation of an emerging Indigenous Environmental Studies and Sciences (IESS) pedagogy.

Building Individuals, Building the Economy
This thesis explores the neoliberal governmentality approach to education for Northern economic development that was prevalent from 2006 to 2015, during Stephen Harper’s period as Prime Minister of Canada. Using a grounded theory approach, this thesis identifies three themes – Indigenous integration, education, and employment for labour force/ economic development – to direct an analysis on programs and funding supported by the Canadian Northern Economic Development Agency, Employment and Social Development Canada, and Indigenous and Northern Affairs Canada. This examination suggests that Federal programming and funding encouraged neoliberal governmentality approaches to Northern development and education. Specifically, the former Government interest in developing an Indigenous work force to serve labour market needs is brought to light. Author Keywords: Economic Development, Indigenous Education, Labour Force Development, Neoliberalism, Territorial North
Building wind energy landscapes
This thesis project explores landowner experiences of wind energy development through an inductive qualitative case study in Huron County, Ontario. The research included in-depth interviews with landowners focused on landscape and community change, participant observation of Environmental Review Tribunals (ERT), the gathering of participant photos, as well as relevant government and industry documents and media reports. The iterative data gathering and analysis were supported by my observations and reflections while living in affected communities and talking to participants. The study demonstrates how the health debate over wind can inform divisions between neighbours, that local politics have been given a token role as a place for resistance to wind energy development that fails to meaningfully influence projects, and that appeals are legalistic and do not provide an outlet, or place for appellants to be heard. Furthermore, the felt experience of tight knit and fragile communities were disrupted through land leases, as well as changes to the landscape. These disruptions impacted connections to, and associations with place, and are shown to have had negative emotional and physical impacts on some individuals. Supporters of wind development tied their mostly positive views of landscape change to a sense of disruption generally throughout the community. Insights from the research lead to a set of suggested actions that might improve the current situation at the levels of provincial policy, planning, local governance and industry practice. Keywords: wind energy policy, planning, landscape, Ontario, rural communities Author Keywords: Affect, landscape, Ontario, planning, Rural communities, Wind energy policy
Bundles and Bloodletting
This thesis addresses the inclusion of women within Classic Maya works of art, consisting of, for this purpose, private-consumption ceramic vessels and large scale public monuments. Through the use of Feminist and Gender Theory, Performance Theory, and Iconographic Theory, the roles of women in iconographically depicted ceremonial performance is assessed. A Microsoft Access database was constructed in order to look at various aspects of female depiction, including but not limited to, bodily action, costume, and paraphernalia. The context, individual action, and associated paraphernalia of women performing numerous roles were analyzed, in which women were found to participate in many of the same roles as men, although there are some roles from which either men or women are excluded, and certain paraphernalia items with which women are not associated. Author Keywords: Archaeology, Feminism, Gender Theory, Iconography, Maya Art, Performance Theory
