Emptying the Den of Thieves: International Fugitives and the Law in British North America/Canada, 1819-1910

This thesis examines how the law dealt with international fugitives. It focuses on formal extradition and the cross-border abduction of wanted criminals by police officers and other state officials. Debates over extradition and abduction reflected important issues of state power and civil liberty, and were shaped by currents of thought circulating throughout the imperial, Atlantic, and common law worlds. Debates over extradition involved questioning the very basis of international law. They also raised difficult questions about civil liberties and human rights. Throughout this period escaped American slaves and other groups made claims for what we would now call refugee status, and argued that their surrender violated codes of law and ideas of justice that transcended the colonies and even the wider British Empire. Such claims sparked a decades-long debate in North America and Europe over how to codify refugee protections. Ultimately, Britain used its imperial power to force Canada to accept such safeguards. Yet even as the formal extradition system developed, an informal system of police abductions operated in the Canadian-American borderlands. This system defied formal law, but it also manifested sophisticated local ideas about community justice and transnational legal order. This thesis argues that extradition and abduction must be understood within three overlapping contexts. The first is the ethos of liberal transnationalism that permeated all levels of state officials in British North America/Canada. This view largely prioritised the erosion of domestic barriers to international cooperation over the protection of individual liberty. It was predicated in large part on the idea of a common North American civilization. The second context is Canada’s place in the British Empire. Extradition and abduction highlight both how British North America/Canada often expounded views on legal order radically different from Britain, but also that even after Confederation in 1867 the empire retained real power to shape Canadian policy. The final context is international law and international legal order. Both extradition and abduction were aspects of law on an international and transnational level. As a result, this thesis examines the processes of migration, adoption, and adaptation of international law.

Semi-volatile Organic Contaminants in the Urban Atmosphere: Spatial and Seasonal Distributions and Implications for Contaminant Transport

Spatial and temporal patterns of semi-volatile organic contaminant (SVOC) concentrations in air and precipitation were investigated at the urban scale in order to improve our understanding of emission sources and factors affecting intra-urban variability. Toronto, Canada was used as a case study. Advances were made in two methods used to examine intra-urban variability, namely passive air sampling and land use regression analysis. The study showed that these methods are useful for assessing local-scale variability, and that passive air sampler concentrations are most reliable when using homologue-specific sampling rates obtained from a co-located low volume sampler. The results of the spatially and temporally distributed sampling demonstrated that the highest atmospheric concentrations of SVOCs were associated with the highest density regions of the urban area. Temporal patterns of elevated concentrations of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) in warm seasons were consistent with temperature-related emission processes such as volatilization and/or ventilation of indoor air. Spatial patterns in air concentrations were influenced by local sources on a scale of <5 km and were explained by factors related to human population activities such as building volume (PBDEs), population density (polycyclic musks, or PCMs), residential, commercial and transportation infrastructure (PAHs), and chemical inventory (PCBs). Industrial activities were not important factors. The link between elevated environmental concentrations and the in-use stock of banned chemicals, such as PCBs and PBDEs, suggest that efforts to control emissions and reduce environmental concentrations must address the removal of current use products, in addition to the bans on new uses of the SVOCs.

A Theoretical Analysis of the Field of Human Simulation and the Role of Emotion and Affect in the Work of Standardized Patients

Standardized Patients (SPs) are lay persons who are employed extensively within health professional education to help teach and assess a range of clinical skills. Individuals trained to take on the physical, historical and emotional aspects of patient stories are integral to the dissemination of collective attitudes, values, and beliefs about what it means to be a competent health professional. As an embodied affective presence literally in front of and often in physical contact with health professionals SPs are a fertile site of knowledge production as well as transformative learning. Their unique contribution is a corollary of both their location as non-clinicians and their pedagogical facility with embodied emotions and affect. SPs in medical education teach about emotion and affect, engage affectively in the presentation of clinical material and as a professionalizing group have developed an educational methodology for facilitating understanding and experience of emotion and affect. In this thesis I examine the field of human simulation and the work of standardized patients (SPs) through critical theoretical perspectives seeking to broaden our understanding of their contributions as a present and future force in health professional education, specifically medical education. Central to my examination is the constitutive role of emotion and affect as they are conceived both within medical education and engaged by standardized patients as media through which different knowledges are produced. My analysis is shaped by poststructuralist feminist writers on emotion, Michel Foucault’s genealogical historical approach, and principally Gilles Deleuze and Felix Guattari’s alternative nomadology as theorized in a thousand plateaus (1987). I intend an alternative reading of the advent of SPs in medical education through a process of mapping rhizomatic networks that include acting, emotion, affect, medicine, and the place of women patients and standardized patients in medical arenas. I have located the current study within an ongoing project of embodied ethical practice and nomadic subjectivity within education specific to human simulation and standardized patients.

Assessing Greenhouse Gas Emissions Mitigation Potential through the use of Forest Bioenergy

Bioenergy production from forest resources offers opportunities to reduce greenhouse gas (GHG) emissions associated with fossil fuel use, reduce non-renewable energy consumption, and provide investment and employment in the forestry sector. These opportunities, however, must be considered within the broader contexts of forest systems. Of particular interest is how bioenergy opportunities impact carbon storage within the forest. This thesis develops a method to integrate life cycle assessment and forest carbon analysis approaches to quantify the total GHG emissions associated with forest bioenergy. Bioenergy production and utilization decisions are then investigated to evaluate opportunities to increase GHG mitigation performance. An accounting method is developed to evaluate the impact of emissions timing on the cost-effectiveness of GHG emissions reductions from biomass-based electricity generation. Applying the integrated life cycle assessment/forest carbon analysis method to a case study of forest bioenergy production in Ontario reveals significant reductions in forest carbon associated with bioenergy production. Wood pellet production from standing trees or harvest residues (displacing coal in electricity generation) would increase total GHG emissions over periods of approximately 40 and 15 years, respectively. Ethanol production (displacing gasoline) would increase GHG emissions throughout the 100-year model period if produced from standing trees; emissions would increase over a period of approximately75 years if produced from harvest residues. Strategic ethanol production decisions (e.g., process energy source, co-location with other processes, co-product selection) can improve GHG mitigation. Co-production of biomass pellets with ethanol performs best among co-product options in terms of GHG emissions; co-location with facilities exporting excess steam and biomass-based electricity further increases GHG mitigation performance. Delayed GHG reductions due to forest carbon impacts the cost of GHG emissions reductions associated with electricity production from forest biomass. Cost-effectiveness is heavily dependent on the time horizon over which global warming impacts are measured and influences the ranking of biomass electricity pathways (biomass co-firing is the most cost-effective pathway between 2020 and 2100; biomass cogeneration is the most cost-effective pathway beyond year 2100). The accounting tools and methods developed within this thesis will to help inform decision-makers in the responsible development of forest bioenergy opportunities and associated policies.

The Past, the Present, and the Practice: An Exploration of the Relationship between Beginning Teachers' Childhood Literacy Experiences and their Literacy Teaching Practices

Abstract This research investigated the influence of the childhood literacy learning experiences of 6 beginning elementary teachers on their literacy teaching practice. This qualitative case study employed 5 interviews and classroom observations of each participant over the first 3 years of his or her teaching. Three main findings emerged from the research. First, participants’ early literacy experiences shaped their identity as students. The participants’ images of themselves as students, in turn, influenced their images of themselves as teachers. Second, the participants’ early literacy learning experiences influenced the types of literacy environments and literacy activities that they provided for their students. Participants employed teaching approaches that had worked for them, or that they believed would have worked for them as students. Third, participants’ early literacy experiences influenced how they understood their students’ learning. The participants who had struggled as students were more focused on detecting and addressing the needs of their students who struggled. Implications for school literacy teaching include understanding and valuing the literacy knowledge and skills that young children bring to school and systematically addressing the needs of students who struggle with school literacy. Implications for preservice teacher education in literacy include an increased focus on supporting student teachers to reflect on how their early literacy learning affects their attitudes and assumptions about learning and teaching, more instruction on how to address the needs of struggling literacy learners, and the provision of a coherent teacher education program that combines theory and practice more effectively. Implications for in-service teacher education in literacy include providing induction programs that are tailored to meet the needs of individual beginning teachers, an expanded range of professional development options, and ongoing opportunities to engage in effective reflective practice. Implications for further research include investigations of the influence of early literacy learning on student achievement and on literacy teacher educators’ practice.

Degradation of Shear Performance of Beams due to Bond Deterioration and Longitudinal Bar Cutoffs

Experimental and analytical research has been conducted to investigate the degradation of shear performance of beams due to bond deterioration and longitudinal bar cutoffs. To achieve the controlled rate of bond degradation, the method of adjustment of the rib height by machining was adopted. Bond behaviour of the milled bars were measured in tension stiffening tests with internally installed strain gauges. Maximum bond stresses for the milled bars were reduced by up to 50% compared to those for normal deformed bar. The bond behaviour of the milled bars were compared with those of the bars subjected to accelerated corrosion. It was confirmed that the stripped bar had the possibility to simulate corroded bars to some extent. Based on the calculations of average tensile stresses in the cracked concrete for each specimen, appropriate tension stiffening factors for each type of bar were suggested and then verified with the 2-dimensional nonlinear finite element analysis program VecTor2. Next, eight simply supported beams were tested. In four of them half of the longitudinal bars were cut off near the supports. Various combinations of normal and machined reinforcing bars were selected for both longitudinal and transverse reinforcement. The predicted shear failure load for the cutoff beam based on the general method for shear design in CSA A23.3-04 was unconservatively estimated. Cutoffs of longitudinal reinforcement resulted in much more significant drops of shear resistance than did bond deterioration of reinforcement. The inclinations of diagonal cracks for the cutoff series were larger than those for the no-cutoff series due to significant concentrations of longitudinal strains near the cutoff locations. Finally modifications to the general shear design method in CSA A23.3-04 were proposed based on the results of VecTor2 analyses for the beam tests. It was found that the influence of bond deterioration on the shear strength of reinforced concrete member can be accounted for by adjusting the tension stiffening factor applied to the equation for β. With respect to bar cutoffs, its influence on shear strength can be expressed by the strain concentration factor applied to the equation for ε_x.

Thanatosensitively Designed Technologies for Bereavement Support

Increasingly, technology impacts how we communicate and behave following the death of a loved one. However, little is known about technology use by the bereaved. This thesis contributes to understanding this phenomenon through three linked studies. These studies establish an appreciation of how technology engages with human mortality, and proposes "thanatosensitive design" (TSD) as an approach for developing such systems. An exploratory study fi rst examines technology use by the bereaved through a survey with follow-up interviews. Findings show that systems for inheriting data and devices are lacking, despite widespread use of technology for remembrance and communication. Using digital assets in social support is selected as a domain for further inquiry. The second study consists of focus groups with bereaved parents at two community organizations complemented by the perspectives of professional bereavement workers. Based on this fieldwork, 6 considerations concerning interpersonal communication, new ways of being, and materiality are presented. These considerations suggest that systems should permit connections with peers, support storytelling activities, and avoid tendencies to "fix" grief, among others. In the final study, I present Besupp - a website that permits bereaved users to engage in online peer-support groups. Besupp applied these design considerations and was deployed in a 10-week study. Nineteen bereaved individuals met in 3 support groups for bereaved parents, partners/spouses, and young adults. Based on system logs/data, questionnaires, and interviews, the study identified barriers to using digital mementos, preferences for online support systems, and issues concerning timing of use. In the discussion, I reflect on the three studies through four thematic lenses: temporality, materiality, identity, and research ethics/methods. I remark on how systems should consider the varying emotional needs of the bereaved over time. In the conclusion, I summarize and reflect on the status of TSD and identify areas for future work concerning social support for the bereaved, and computing's role at the end of life more broadly.

Structural and Functional Aspects of Brain Development in Children with an Autism Spectrum Disorder (ASD)

Research suggests that brain growth follows an abnormal trajectory in children with autism spectrum disorders (ASD). A better understanding of when and how patterns of brain development diverge from that seen in typically developing children could yield insight into the etiology of the disorder, and resulting symptomatology. To investigate this hypothesis, three studies examined the relation between structural and functional brain measures and age in a group of children with an ASD, aged 6 to 14 years. Age by group interactions were found in all three studies, providing further evidence that brain development may follow an atypical trajectory in ASD. Study 1: Differences in the relation between structural indices and age were found in grey matter volume, surface area and thickness, as well as in cortical thickness of specific regions in the left inferior frontal gyrus (BA 44) and left precuneus. These measures of grey matter structure generally decreased with age in the ASD children, compared to little or no change with age in the typically developing children. Study 2: Differences in the relation between age and measures of longitudinal, radial and mean diffusivity were found in frontal, long distant, interhemispheric and posterior white matter tracts; diffusivity decreased with age in the typically developing group, but showed little or no change in the ASD group. Study 3: Differences in the relation between BOLD activation on a set-shifting task and age were found in brain regions important for cognitive flexibility, such as areas of prefrontal, right insula and parietal cortex. These effects were mainly due to decreasing activation with age for the ASD group, but increasing or no age-related change in the TD group. The findings of these three studies provide converging evidence in support of an hypothesis of dysregulated brain development in this population, which could have significant, compounding effects on the development of neural connectivity, and contribute to atypical cognitive development in children with ASD.

Measurements of Water-soluble Composition of Fine Atmospheric Particulate Matter (PM2.5) and Associated Precursor Gases via Ambient Ion Monitor-ion Chromatography (AIM-IC)

Atmospheric fine particulate matter (PM2.5), which is mostly formed in the atmosphere from precursor gases, contributes to numerous environmental and health concerns. Quantifying the ambient concentrations of PM2.5 and precursor gases can be challenging. Hence, many scientific questions about the formation, chemical composition, and gas/particle partitioning of PM2.5 remain unanswered. Ambient Ion Monitor - Ion Chromatography (AIM-IC) was characterized and utilized to measure the water-soluble composition of PM2.5 (dominated by pNH4+, pSO42-, and pNO3-) and associated precursor gases (dominated by NH3(g), SO2(g), and HNO3(g)) during two field campaigns. The AIM-IC detection limits for hourly sampling were determined to be 3 - 45 ng m-3. The response time for “sticky” gases was significantly improved with a nylon denuder membrane. A novel inlet configuration for the AIM-IC, which minimizes sampling inlet losses and carryover in sample analyses, was implemented. Measurements from the BAQS-Met 2007 campaign were utilized to assess the accuracy of the AURAMS model and investigate gas/particle partitioning in SW Ontario. Due to high sulphate levels, NH3(g) was the limiting chemical factor in the formation and gas/particle partitioning of PM2.5. The errors in the predictions of relative humidity and free ammonia were responsible for the poor agreement iii between modelled and measured pNO3- values. The AIM-IC measurements from the CalNex 2010 study were compared to the CMAQ model and utilized to investigate the gas/particle partitioning in Bakersfield, CA. Very high NH3(g) concentrations were observed, and the formation and partitioning of PM2.5 was limited by HNO3(g) and H2SO4. Evidence of rapid removal of HNO3(g) by interactions with super-micron dust particles, and possibly with the alkaline surface was found. CMAQ exhibited significant biases in the predicted concentrations of pSO42-, NH3(g) and HNO3(g).
