This collective case study examined the factors affecting the collaborative relationship between teachers and early childhood educators (ECEs) teaching together in elementary schools as Early Learning Teams in the first year of implementation of full-time kindergarten in Ontario. There are six major adjustments required concurrently by the Ontario government’s new policy in all kindergarten classrooms: team-teaching (sharing instruction, not just classroom management); supporting ECEs as new staff; changing from theme-based to inquiry-based; balancing the School District’s literacy goals with provincial play-based curriculum; double the instructional time, and the increased number of children in the classroom (up from 19 to 24-30). Two of the four classrooms studied in a rural Ontario school district were full-day, every day kindergartens (FDK) for 4 and 5 year olds and the other two were alternate full-days. Data were collected through classroom observations and interviews with principals, kindergarten teachers and ECEs. Case study theory guided the collection and analysis of data with open coding of transcripts, active code notes and memos to help answer the question of how to best implement FDK programs in Ontario. Results indicated that the FDK Team relationship itself enabled and constrained classroom instructional strategies, which would in turn have an impact on student outcomes. Collaborative practice involved a process that was affected by both internal factors (such as teacher foreknowledge of ECE skills), and thirteen external factors which arose from government and school district mandates, as well as practices of the school principal. Examples are: planning time, pay differential, hiring practices and adjusting to the new curriculum at the same time as the team adjusts to team teaching. The collaboration of more than 9,500 teacher and ECE teams is key to the success of Ontario’s new full-time early learning program. The education sector needs to adopt the long-established business practice of supporting team development through recognizing progressive teaming stages, such as those identified by Tuckman (1965). Recommendations are made for principals, school districts offices, government policy, FDK teachers, ECEs, and colleges that provide ECE training. A mnemonic for the four attributes evident in high-functioning collaborative integrated teaching teams (RISE) is proposed.
Vulnerability, Care, Power, and Virtue: Thinking Other Animals Anew
Keywords: Vulnerability

Technologies of Power
Technologies of the Self

This thesis is a work of practical philosophy situated at the intersection of bioethics, environmental ethics, and social and political thought. Broadly, its topic is the moral status of nonhuman animals. One of its pivotal aims is to encourage and foster the “sympathetic imaginative construction of another’s reality” and to determine how that construction might feed back on to understandings of ourselves and of our place in this world that we share with so many other creatures. In the three chapters that follow the introduction, I explore a concept (vulnerability), a tradition in moral philosophy (the ethic of care), and a philosopher (Wittgenstein) that are not often foregrounded in discussions of animal ethics. Taken together, these sections establish a picture of other animals (and of the kinship that humans share with them) that can stand as an alternative to the utilitarian and rights theories that have been dominant in this domain of philosophical inquiry. In my fifth and sixth chapters, I extend this conceptual framework by turning to the work of Michel Foucault. Here, I develop a two-pronged approach. The first direction – inspired by Foucault’s work on “technologies of power” – is a broad, top-down engagement that explores many of the social apparatuses that constitute the power-laden environments in which human beings and other animals interact. I focus on the slaughterhouse in particular and argue that it is a pernicious institution in which care and concern are rendered virtually impossible. The second direction – inspired by Foucault’s later work on “technologies of the self” – is a bottom-up approach that looks at the different ways that individuals care for, and fashion themselves, as ethical subjects. Here, I examine the dietary practice of vegetarianism, arguing that it is best understood as an ethical practice of self-care. One virtue of my investigation is that it enables a creative synthesis of disparate strands of philosophical thought (i.e. analytic, continental, and feminist traditions). Another is that it demonstrates the philosophical importance of attending to both the wider, institutional dimension of human-animal interactions and to the lived, embodied experiences of individuals who must orient themselves and live their lives within that broader domain. This more holistic approach enables concrete critical reflection that can be the impetus for social, and self-, transformation.
Demand for Health among Canadians: Roles of Immigration Status, Country of Origin and Year since Migration
Keywords: demand for health

Canada

This thesis investigates the effects of immigration status, country of origin, and duration in Canada on three main health outcomes, namely health care utilization, occurrences of hypertension and heart disease, and body mass index. The first two chapters are cross-sectional studies that utilize data derived from linked national health survey and Ontario databases, whereas the third chapter is a longitudinal study which draws data from the longitudinal National Population Health Survey (NPHS). The first chapter examines the role of immigration status and country of origin in explaining the use of three types of health services: primary care physicians, specialists, and hospitals. The findings suggest that immigrants, especially those who are male and have low educational attainment, use more primary care physicians than comparable non-immigrants. However, immigrants are found to use fewer expensive health services, i.e. specialist and hospital care, compared to Canadian-born residents. Likewise, immigrants from non-traditional source countries make even fewer visits to specialists than do those who came from traditional source countries. The second chapter investigates the associations of immigration status, occurrence of hypertension, and occurrence of heart disease. Findings from this chapter show that immigrants have comparable odds of hypertension and heart disease to those of Canadian-born residents after adjusting for other factors. The third chapter examines the effects of time since arrival in Canada on the change in BMI over the 14-year period. This chapter shows that, holding other factors constant, an additional year in Canada leads to a 0.14% increase in an individual’s BMI. This association is found to be more pronounced for women than men and for married than non-married individuals. The effect of time since arrival in Canada on the change in BMI is reduced to 0.07% after controlling for sample selection bias, suggesting that by ignoring the sample selection issue, the effects of time since arrival in Canada on the change in BMI may be overestimated.
The Development of a Phenotype for Lung Disease Severity in Cystic Fibrosis and its Application in the CF Gene Modifier Study
Keywords: Cystic Fibrosis

Mortality Attrition

Genetic studies of lung disease in Cystic Fibrosis are faced with the challenge of identifying a severity measure that accounts for chronic disease progression and mortality attrition. Further, combining analyses across studies requires common phenotypes that are robust to study design and patient ascertainment. This thesis uses data from the North American Cystic Fibrosis Modifier Consortium (Canadian Consortium for CF Genetic Studies (CGS), Johns Hopkins University Twins and Siblings Study (TSS), and University of North Carolina/Case Western Reserve University Gene Modifier Study (GMS)), to calculate two novel phenotypes using age-specific CF percentile values of FEV1 (Forced Expiratory Volume in 1 second), with adjustment for CF age-specific mortality. The normalized residual, mortality adjusted (NoRMA) was designed for population based samples, while KNoRMA, using Kulich percentiles, is robust to sample ascertainment; both account for the effects of age-related disease progression and mortality attrition. NoRMA was computed for 2122 patients representing the Canadian CF population. KNoRMA was computed for these 2122 patients and also 1137 extreme phenotype patients in the GMS study and 1323 patients from multiple CF sib families in the TSS study. Phenotype was distributed in all three samples in a manner consistent with ascertainment differences, reflecting the lung disease severity of each individual in the underlying population. The new phenotype was highly correlated with the previously recommended mixed model phenotype1; 2, but computationally much easier and suited to studies with limited follow up time. As an example of its use, KNoRMA was used to test the association between locus variants in a previously published candidate gene, Transforming Growth Factor β1(TGFβ1), and lung function in CF, in an attempt to provide insight into discrepant results in the literature. A disease progression and mortality adjusted phenotype reduces the need for stratification or additional covariates, increasing statistical power and avoiding possible interpolation distortions.
Structure and Properties of Nanomaterials: From Inorganic Boron Nitride Nanotubes to the Calcareous Biomineralized Tubes of H. dianthus
Keywords: boron nitride nanotubes

Several nanomaterials systems, both inorganic and organic in nature, have been extensively investigated by a number of characterization techniques including atomic force microscopy (AFM), electron microscopy, Fourier transform infrared spectroscopy (FTIR), and energy dispersive x-ray spectroscopy (EDX). The first system consists of boron nitride nanotubes (BNNTs) synthesized via two different methods. The first method, silica-assisted catalytic chemical vapour deposition (SA-CVD), produced boron nitride nanotubes with different morphologies depending on the synthesis temperature. The second method, growth vapour trapping chemical vapour deposition (GVT-CVD), produced multiwall boron nitride nanotubes (MWBNNTs). The bending modulus of individual MWBNNTs was determined using an AFM three-point bending technique, and was found to be diameter-dependent due to the presence of shear effects. The second type of nanomaterial investigated is the biomineralized calcareous shell of the serpulid Hydroides dianthus. This material was found to be an inorganic-organic composite material composed of two different morphologies of CaCO3, collagen, and carboxylated and sulphated polysaccharides. The organic components were demonstrated to mediate the mineralization of CaCO3 in vitro. The final system studied is the proteinaceous cement of the barnacle Amphibalanus amphitrite. The secondary structure of the protein components was investigated via FTIR, revealing the presence of β-sheet conformation, and nanoscale rod-shaped structures within the cement were identified as β-sheet containing amyloid fibrils via chemical staining. These rod-shaped structures exhibited a stiffer nature compared with other structures in the adhesive, as measured by AFM nanoindentation.
Knowledge, Truth, and Schooling for Social Change: Studying Environmental Education in Science Classrooms

While recent research trends in science education have focussed the collective attention at utilizing the science curriculum as a means towards positive social change, such efforts have largely been predicated on understandings of the nature of knowledge and truth as socially constructed entities. Through this lens of social constructivism, knowledge is said to bear the signature of individuals and institutions in power, and therefore extant knowledge is considered to be the vehicle for further oppression of disadvantaged groups. There are at least two ways in which this argument is deeply flawed—social constructivism accords to itself epistemic positions it denies others, and an intellectually honest application of its principles leads to a position where there is no way to distinguish between better or worse positions on issues. In contrast, the principle of social realism takes a ‘middle path’, acknowledging the social reality of knowledge construction but disavowing the relativism of social constructivism. Through this epistemological foundation, implications arise for curriculum theory—how is it that we may discriminate forms of knowledge for in/ex-clusion into the school curriculum? In this study, I consider the curriculum changes in the Ontario elementary science anxd technology curriculum. I ask two key questions: (i) What are the effects of the curriculum revisions on the knowledge content of the science curriculum? and: (ii) What are the characteristics of science pedagogy in fulfilment of these curriculum changes? I develop instruments to analyze curriculum documentation, and classroom pedagogy. The major findings of this project include: (i) the curriculum revisions have added environmental knowledge expectations with varying degrees of disconnection from the scientific content knowledge; (ii) knowledge expectations removed to accommodate environmental expectations constituted important scientific principles; (iii) environmental pedagogy in science classrooms reflected the disconnection between science and environmental knowledge, most obviously in the upper grades where the degree of boundary maintenance between knowledge forms was strongest; (iv) this disconnection between environmental and scientific knowledge forms inhibited the cumulative modality of knowledge (re)production. A discussion of results and the general principles of the importance of knowledge concludes the project.
Clinical Implications of HIV-1, HSV-2 Co-infection and Opportunities for Intervention
Keywords: HIV
Herpes simplex virus type 2

HSV-2 may have adverse consequences in HIV. I evaluated the impact of HSV-2 co-infection on (highly active antiretroviral therapy)-untreated HIV infection in a systematic review of observational studies (study 1) and a retrospective cohort (study 2). I further evaluated whether HSV reactivation rates in co-infected persons differ by use of suppressive cART (study 3). Study 1 found modest evidence that HSV-2 seropositivity may be associated with accelerated progression to opportunistic infection or clinical AIDS, but not with increased HIV viral load. Some evidence suggests that HSV-2 disease activity is associated with increased HIV viral load and decreased CD4 counts. Study 2 compared rates of CD4 count change by HSV-2 status (Focus HerpeSelect ELISA) among 218 patients with a past period of ART-untreated follow-up using mixed linear regression models. No significant difference in the rate of CD4 count change was observed in HSV-2 seropositives at +13.6 cells/mm3/year (p=0.12) in univariate analysis, and -4.5 cells/mm3/year (p=0.68) in analysis adjusted for sex, HSV-1, oral and genital HSV symptoms, immigrant status, and immigrant*time interaction. These findings support the need for carefully designed and executed studies of HSV-2 suppression as an adjunctive management strategy for HIV disease, but raise questions regarding the exact mechanism of negative synergy between these viruses and the relative importance of HSV-2 latency and replication in driving these effects. In Study 3, 44 cART-naïve and 41 treated (HIV RNA<50 copies/mL) HIV+ adults with HSV-1 and/or 2 co-infection collected oral, genital and anal swabs daily for 28 days. Negative binomial models were used to quantify the relationship between cART and HSV shedding (Roche LightCycler HSV1/2). Overall HSV shedding was low, at a median (IQR) of 3.6% (0, 14.3%) of days. No relationship was seen between cART and HSV-1 or 2 shedding in univariate (RR=1.55, 95%CI=0.83,2.87) or multivariate analysis adjusted for sex, baseline CD4, recent immigrant status, and time since HIV diagnosis (aRR=1.05, 95%CI=0.43,2.58). Null results were also observed for HSV-1 and HSV-2 considered separately. That HSV shedding persists despite cART suggests that trials of anti-HSV drugs for improving HIV outcomes may be warranted in such patients.
Transfer Relations in Essentially Tame Local Langlands Correspondence
Keywords: representation theory
number theory

Let F be a non-Archimedean local field and G be the general linear group GLn over F. Bushnell and Henniart described the essentially tame local Langlands correspondence of G(F) using rectifiers, which are certain characters defined on tamely ramified elliptic maximal tori of G(F). They obtained such result by studying the automorphic induction character identity. We relate this formula to the spectral transfer character identity, based on the theory of twisted endoscopy of Kottwitz, Langlands, and Shelstad. In this article, we establish the following two main results. (i) To show that the automorphic induction character identity is equal to the spectral transfer character identity when both are normalized by the same Whittaker data. (ii) To express the essentially tame local Langlands correspondence using admissible embeddings constructed by Langlands-Shelstad χ-data and to relate Bushnell-Henniart's rectifiers to certain transfer factors.
The Effects of Weather and Climate Variability on the Well-being of a Rural and Urban Aboriginal Group in Ontario, Canada

The role of weather and climate variability on the health of Aboriginal people in Fort Albany and Toronto, Ontario, Canada is explored through four complementary research studies. The first study examined past temperature trends of Fort Albany (using climate records of Moosonee) and Toronto. Temperature variability was found to be greater in Moosonee than in Toronto, and day to day temperature minimum (Tmin) threshold exceedances of 5 degrees Celsius was found to have significantly declined in both Toronto and Fort Albany. The second study explored the effects of climate change on a rural First Nation group in Fort Albany. Observed environmental changes include changes in the timing of seasons, spring melt and ice freeze-up; warmer seasons, an increase in extreme and unpredictable weather, and changes in animal patterns. These changes have affected subsistence harvesting activities and community infrastructure, which have lead to increased health risks, though many community members have exhibited resiliency and adaptation. The third study compared current health status between an urban Aboriginal and non-Aboriginal group. Urban Aboriginal participants were found to be at greater risk to psychological distress and seasonal affective disorder (SAD) than non-Aboriginal participants. Moreover, those who self-rated their health as poor/fair were more likely to exhibit psychological distress than those who self-rated their health as good/very good/excellent. The fourth study compared the effects of weather and seasonal change among a rural First Nation group, an urban Aboriginal group and an urban non-Aboriginal group. Urban Aboriginal participants were most affected by weather while rural Aboriginal (i.e. First Nation) participants were least affected by weather. These studies demonstrate that both urban and rural Aboriginal groups may be at risk to climate change and weather-related changes; though specific implications may differ due to different lifestyles and capacities to adapt to environmental conditions.
The Epistemology of Measurement: A Model-based Account
Keywords: philosophy of science

Measurement is an indispensable part of physical science as well as of commerce, industry, and daily life. Measuring activities appear unproblematic when performed with familiar instruments such as thermometers and clocks, but a closer examination reveals a host of epistemological questions, including: 1. How is it possible to tell whether an instrument measures the quantity it is intended to? 2. What do claims to measurement accuracy amount to, and how might such claims be justified? 3. When is disagreement among instruments a sign of error, and when does it imply that instruments measure different quantities? Currently, these questions are almost completely ignored by philosophers of science, who view them as methodological concerns to be settled by scientists. This dissertation shows that these questions are not only philosophically worthy, but that their exploration has the potential to challenge fundamental assumptions in philosophy of science, including the distinction between measurement and prediction. The thesis outlines a model-based epistemology of physical measurement and uses it to address the questions above. To measure, I argue, is to estimate the value of a parameter in an idealized model of a physical process. Such estimation involves inference from the final state (‘indication’) of a process to the value range of a parameter (‘outcome’) in light of theoretical and statistical assumptions. Idealizations are necessary preconditions for the possibility of justifying such inferences. Similarly, claims to accuracy, error and quantity individuation can only be adjudicated against the background of an idealized representation of the measurement process. Chapters 1-3 develop this framework and use it to analyze the inferential structure of standardization procedures performed by contemporary standardization bureaus. Standardizing time, for example, is a matter of constructing idealized models of multiple atomic clocks in a way that allows consistent estimates of duration to be inferred from clock indications. Chapter 4 shows that calibration is a special sort of modeling activity, i.e. the activity of constructing and testing models of measurement processes. Contrary to contemporary philosophical views, the accuracy of measurement outcomes is properly evaluated by comparing model predictions to each other, rather than by comparing observations.
