Virtual Voices
A consistent provincial approach to capacity planning for rehabilitative care had been identified as a critical gap in the field of health care in Ontario (Rehabilitative Care Alliance, 2015a). In response, the rehabilitative care alliance (RCA) developed a needs based hip fracture capacity planning canvas together with persons and families. This research utilized computer assisted participation (CAP) to gather additional perspectives from Virtual Voices via an on-line survey. The results of the Virtual Voices survey were compared to Ontario’s RCA hip fracture patient focus group findings. CAP facilitated more voices and more ideas through virtual engagement. The survey method required 97% (10.6 hours) less time than the focus group. The Virtual Voices respondents provided validation of the focus groups’ confirmation of the rehabilitative care needs, locations and most core team members as well as identified new ideas. The results support the implementation of a needs-based capacity plan that enables individualized care planning. This research provides a blueprint for the ongoing engagement of persons and families in the co-creation of a sustainable rehabilitative care system. A dashboard and e-health app would enable ongoing co-design, monitoring and evaluation.

Ethnoarchaeology in the Traditional Villages of Bagan, Myanmar
This thesis investigates the current composition of traditional settlements located in and around the remains of the ancient, walled and moated, regal-ritual epicenter of Bagan, Myanmar. This study also provides some suggestions as to strategies that may be employed by future settlement archaeology projects in the region. To achieve the aims of this study, an ethnoarchaeological approach was employed at ten village sites located on the Bagan plain: Thè Pyin Taw, Thè Shwe Hlaing, Zee Oo, Kon Sin Kyi, Kon Tan Gyi, Minnanthu, Hpauck Sein Pin, Thah Tay Kan, East Pwa Saw, and West Pwa Saw. The data obtained from these villages, compounds, and houses is used to generate a version of the average Bagan village, compound (i.e., house lot), and house. The model Bagan village, compound, and house are in turn used to provide the basis for suggestions to be used in future settlement archaeology projects.

When He Reigns, It Pours
This thesis examines the symbolic meaning and significance that the elite attached to water in ancient Bagan. Through the use of ethnoarchaeological, epigraphic, archaeological, and iconographic data, this study examines the role of water as part of rituals performed by the royal court and the ways in which the royalty of Bagan, in particular King Kyansittha, negotiated, appropriated and disseminated water symbolism to fulfill his interests. Data indicates that the symbolic and religious meaning of water was intricately attached to Buddhist concepts of fertility, wisdom, creativity, and protective powers. Evidence suggests that the royalty employed different techniques to appropriate and disseminate water ritualization, including the performance of water rituals that were closely attached to kingship, power, and ruler legitimacy, the promotion of an alliance with creatures capable of increasing rains and fertility, and the use of analogies that compared the properties of water with the virtues of the king.

Advanced broadband CARS microscopy based on a supercontinuum-generating photonic crystal fiber
I have developed and improved a coherent anti-Stokes Raman scattering (CARS) microscope based on the spectral focusing (SF) technique. The CARS microscope uses an 800 nm oscillator and a photonic crystal fibre module to generate the supercontinuum Stokes. The photonic crystal fibre was originally designed to generate light beyond 945 nm which is useful for CARS microscopy in the CH/OH frequencies but essentially prevents access to the important fingerprint region at lower frequencies. With expert and nontraditional approaches to generating supercontinuum with sufficient power at wavelengths below 945 nm, I substantially extend the usefulness of the module for SF-CARS microscopy deep into the fingerprint region. Moreover, with the invention of a dynamic supercontinuum generation scheme we call "spectral surfing," I improve both the brightness of the CARS signal and extend the accessible CARS frequency range to frequencies as low as 350 cm$^{-1}$ and as high as 3500 cm$^{-1}$---all in a single scan-window. I demonstrate the capabilities of our broadband SF-CARS system through CARS and four-wave mixing hyperspectroscopy on samples such as astaxanthin, lily pollen and glass; liquid chemicals such as benzonitrile, nitrobenzene and dimethyl sulfoxide; and on pharmaceutical samples such as acetaminophen, ibuprofen, and cetirizine. Furthermore, In search of more useful Stokes supercontinuum sources, I compare the performance of two commercial photonic crystal fibre modules for use in SF-CARS applications, ultimately finding that one module provides better spectral characteristics for static supercontinuum use, while the other provides improved characteristics when spectral surfing is implemented.

At the Intersection Between History and Fiction in Biography and Autobiography; A Repositioning, Using the Quest for the Historical Jesus as a Case Study
The modern sense of historicism developed over time that brought different textures at the intersection between history and fiction. The life of Jesus of Nazareth, prolifically researched after Herman Reimarus (1694-1768) right until today – a phenomenon known as The Quest for the Historical Jesus – provides an instructive case study for a wider discussion about the intersection between history and fiction in biography and autobiography. As a result of these centuries of Jesuanic research, one can identify a set predictable challenges which life-writing may need to confront. Furthermore, interesting historiographical criteria to detect factual authenticity versus factual inauthenticity for life-writing were also developed. Nevertheless, the depth of disagreement about a well-researched narrative such as the Jesuanic chronicle can eventually feel almost insurmountable. Pessimism, in fact, has become widespread. Thus, this dissertation raises the question: Is it but a vain attempt to search for truth by attempting to draw a sharp line between fiction and history? Hence, the discussion moves to Mikhail Bakhtin whose insistence on dialogism rather than truth seeking provides a more relational approach to appreciating the intersection between history and fiction in biography and autobiography. Author Keywords: biography, Copernicanism, dialogism, fiction, historicism, monologism
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.

Opportunities for Carbon Dioxide Capture and Storage in Building Materials
The “upfront” embodied carbon (EC) of building materials includes the accumulated greenhouse gas (GHG) emissions resulting from harvesting, manufacturing and transportation processes, and is becoming more widely recognized as a major source of global GHGs. The aim of this study is to demonstrate the potential for buildings to go beyond reduced or zero GHG emissions and to become– at least temporarily – a negative emissions technology, namely places of net storage of carbon. The study examines the EC for two samples of low-rise residential buildings that are representative of the North American wood-framed typology: a single-unit raised bungalow of 185m2 and an eight-unit, four-story of 935 m2. Data from Environmental Product Declarations (EPDs) for a wide variety of materials that could feasibly be used to construct the sample buildings are used to calculate the total EC for four different material assemblies in each building type: High EC, Typical EC, Best Conventional EC and Best EC. Results demonstrate the upfront embodied carbon can vary widely, ranging from a worst-case scenario of 415 kgCO2e/m2 of net emissions to a best case of 170 kgCO2e/m2 of net carbon storage by using biogenic (plant-based) materials. In addition, an energy modeling analysis of the buildings was conducted for the Toronto, Ontario climate to compare the EC with the operational carbon (OC) emissions. The results show that achievable reductions in EC could provide more than four times the overall GHG reductions than energy efficiency improvements to reduce OC between 2020 and 2050. The building model with both the lowest EC and OC is shown to have net carbon storage for several centuries. At the current scale of US residential construction, annual carbon storage in residential buildings as modeled could reach 30,000,000 tonnes, the equivalent of 10 coal-fired power plants. The immediate impact of large-scale GHG reductions from the use of carbon-storing materials is demonstrated to be worthy of consideration for the building industry and related policy makers.

History of Canada's UFO Investigation, 1950-1995
From 1950-1995, the Canadian government investigated the phenomenon of unidentified flying objects (UFOs), amassing over 15,000 pages of documentation about, among other matters, nearly 4,500 unique sightings. This investigation was largely passive and disconnected, spread across a number of federal departments and agencies that infrequently communicated about the subject. Two official investigations, Project Magnet and Project Second Storey, were initiated in the early 1950s to study the topic. The government concluded that the UFO phenomenon did not “lend itself to a scientific method of investigation,” and terminated the projects. After this point, the investigation entered a state of purgatory, with no central communication, and every government department eager to pass the responsibility onto someone else. As such, Canadian citizens writing to the government for straight answers to the UFO enigma were often on the receiving end of what they called “doublespeak.” Citizens were seeing things in the sky and wanted the government to simply tell them what they were. The government was unable and unwilling to do this, and over time frustration grew on both sides. What began for the government, in its own words, as an irritating intrusion into more important matters, became the catalyst for a dynamic of mutually-reinforced mistrust between state and citizen during the postwar period. This dissertation offers a chronological history of the efforts that the Canadian government and citizens made to investigate UFOs, and when and why these efforts came into conflict. The main argument is that the Canadian state attempted to use UFOs as a site to assert its modernity during a time of uncertainty and anxiety over its legitimacy, by drawing on the cultural authority of the scientific community. The project was one of ridding the public of ignorance and creating instead a more rational citizen. This attempt ran up against beliefs and attitudes that some citizens shared, that tapped into a spirit of anti-authoritarianism present during the 1960s and even earlier. These citizens considered themselves to be iconoclasts, unmoved by claims of expertise, and accused the government of conspiracy theory. These approaches fed into one another, contributing to further misunderstanding and conflict. The history of Canada’s UFO investigation is thus more broadly a history of changing attitudes toward authority and expertise in the postwar era.

That '70s Strike Support
This thesis examines three Ontario strikes during the 1970s: the Dare Foods, Ltd. strike in Kitchener, Ontario, 1972-1973; the Puretex Knitting Company strike in Toronto, 1978-1979; and the Inco strike in Sudbury, 1978-1979. These strikes highlight gender issues in the Canadian food production, textile, and mining industries in the 1970s, industries that were all markedly different in size and purpose, yet equally oppressive towards working women for different reasons, largely based on the regional character of each city the strikes took place in. In Kitchener, the women’s movement worked closely with the Dare union local and the left to mobilize against the company and grappled with the difficulties of framing women’s inequality within the labour movement. At Puretex, immigrant women workers were subject to electronic surveillance as a form of worker control, and a left-wing nationalist union needed to look outside of the Canadian Labour Congress (CLC) for allies in strike action. At Inco, an autonomous women’s group formed separate from the United Steelworkers of America (USWA) but struggled to overcome a negative perception of women’s labour activism in Sudbury. Ultimately, these strikes garnered a wide variety of support from working women and feminist groups, who often built or had pre-existing relationships with Canadian and American trade unions as well as the left-wing milieu of the 1970s. This thesis uses these strikes as case studies to argue that despite the complicated and at times uneven relationship between feminism, labour, and the left in the 1970s, feminist and left-wing strike support was crucial in sustaining rank-and-file militancy throughout the decade and stimulating activist careers for women in the feminist movement, in unions, and on the left. Author Keywords: 1970s, feminism, labour, left-wing, militancy, working-class
Indirect Effects of Hyperabundant Geese on Sympatric-Nesting Shorebirds
Rising populations of Lesser Snow and Ross’ geese (hereafter collectively referred to as light geese) breeding in the North American Arctic have caused significant environmental change that may be affecting some populations of nesting shorebirds, which in contrast to geese, have declined dramatically. In this thesis I examine the indirect effects of light geese on sympatric-nesting shorebirds. I first conduct a literature review of the effects of light geese on northern wildlife and outline multiple mechanisms in which geese may affect shorebirds in particular. Using bird survey data collected in plots situated across the Canadian Arctic from 1999 to 2016, I then identify spatial effects of light goose colonies on shorebird, passerine, and generalist predator densities. The densities of cover- nesting shorebirds and passerines were depressed near goose colonies while the densities of open-nesting shorebirds were less so. Next, using habitat data collected at random sites and shorebird nest sites situated at increasing distances from a goose colony on Southampton Island, Nunavut, I outline the effects of geese on shorebird nest site selection. I found that the availability of sedge meadow and amount of lateral concealment increased as a function of distance from goose colony; cover-nesting shorebirds selecting nest sites with less concealment and sedge meadow near the colony. Then, to characterize spatial effects of light geese on predators and risk of predation I used time-lapse cameras and artificial shorebird nests placed at increasing distances from the goose colony. Activity indices of gulls, jaegers, and foxes were all negatively correlated with distance from the goose colony while the reverse was true for artificial nest survival probability. Finally, I relate changes in ground cover to goose use and link these changes to variation in invertebrate communities. I then use DNA metabarcoding to characterize the diet of six shorebird species across study sites and identify inter-site variation in the biomass of dominant shorebird prey items. Prey item biomass was elevated at the two study sites near the goose colony potentially indicating an enhancing effect of goose fecal deposition. Overall, I show that light geese interact with shorebirds in multiple ways and negatively affect their habitat availability, nest site selection, and risk of predation, effects that likely outweigh the positive effects of enhanced prey availability.

Neolithic Resource Use and Adaptation in the Eastern Gobi Desert
Stone axes and adzes first appeared in the eastern Gobi Desert at 8.0 cal BP and were incorporated into the technological package. At the same time, changes in local ecological conditions reflect a transition from continuous grass/shrub-steppe across the Mongolian Plateau to the development of dispersed patches of dune-field wetland oases and high-elevation forests. This thesis focuses on exploring the adoption and function of axes and adzes in the eastern Gobi Desert and their relationship to the development of these new forested ecologies. Using an experimental and use-wear approach, I analyze 29 axes and adzes from four sites in the eastern Gobi Desert of Mongolia and Inner Mongolia. Results indicate that axes and adzes were primarily used for woodworking but include other activities. Furthermore, the adoption and manufacture of axes and adzes represent an increasing investment in producing formal technologies as resources within these new diverse ecological patches were intensively utilized.

Indigenous Knowledge in Contemporary Public Education
This study provides important perspectives and guidance for educators in Ontario to assist in integrating Indigenous content into public education programs – both in schools and other community educational settings. It explores how Indigenous worldviews provide unique insights for holistic education and learning how to live sustainably in place. The study also focuses on approaches to education, comparing Eurocentric and Indigenous philosophies and pedagogies, as indicators of differing value systems. Through a combination of literature review and personal interviews with eleven influential Indigenous and non-Indigenous educators in the Peterborough area, the study explores the potential for Indigenous perspectives to enhance the wellbeing and personal learning journey of all students, regardless of their backgrounds. The research concludes with recommendations for educators on how to begin integrating Indigenous Knowledge throughout programming in appropriate, respectful ways that celebrate diversity, develop positive relationships and build healthier, more sustainable communities. Author Keywords: Education, Environment, Indigenous Knowledge, Pedagogy, Reconciliation, Worldviews
