This thesis is an examination of how white women in interracial relationships and/or white mothers of biracial children understand race. Through interviews with six self-identified white women who have black-white biracial children, I seek to understand what role racism plays in their lives and whether these women have a heightened consciousness about race as a result of being in an interracial family. Using their narratives and a spatial framework, I explore the concept of white supremacy, whiteness and blackness, representations of white femininity and black masculinity in the media, and how white women in interracial relationships cross the colourline in their everyday lives. I suggest that white women learn about colourlined spaces in public, but that they also learn about blackness and teach their biracial children about antiracism in private spaces. Overall, white women need to negotiate rules and norms within racial hierarchies in order to navigate white supremacy.
Everyday Tension between Collegiality and Managerialism: Administrators at a Canadian Research University

This thesis is an exploratory study focusing on the tension between managerialism and collegiality experience by mid-level academic administrators in Canadian higher education. The study is a constructivist analysis of the every day, lived experiences of the participants working in a single, large university. Semi-structured interviews were conducted with 6 academic administrators that report directly to a Vice-President Academic. The analysis of these detailed interviews suggests that collegiality appears to be alive and well at the university included in this study. Administrators described consultative, collegial processes with shared decision making. However, the activity of developing and managing budgets was described by participants as the responsibility of the dean and these processes were neither collegial nor consultative. There is a need for further research on the experience and work of academic administrators in Canadian higher education.
Storying for Social Justice: A Professional Learning Journey
Keywords: social justice education
developing agency
empowering of students from marginalized communities
curriculum integration
writing

This thesis was an examination of my own practice in critical literacy teaching for social justice in Language Arts. The intention was to evaluate the effectiveness of a teacher inquiry process in improving social justice based instructional practice. Particularly, developing critical literacy skills with students was a focus. Emphasis was placed on the role of “text analyzer”, who “understands that texts are not neutral, that they represent particular views and perspectives, that other views and perspectives may be missing, and that the design of messages of texts can be critiqued and alternatives considered” (Freebody & Luke, 1990). By examining perspectives and points of view in text, students moved toward understanding agency, oppression and empowerment. Learnings included identifying an operational framework for developing a social justice orientation to teaching and integrating social justice teaching across a variety of curriculum areas.
Workplace Learning of Canadian Retail Bank Branch Workers in Conditions of Organizational Restructuring
Keywords: Workplace Learning
Bank workers' learning practices
Financial Sector

Learning and restructuring
Learning and automation

This thesis examines retail bank workers’ informal learning practices in a major Canadian bank under conditions of rapid organizational restructuring and ongoing automation during the mid- to late-1990s. Based on a national survey of bank workers’ learning practices and ethnographic fieldwork in three branches, the thesis’s key findings are as follows. The poor learning environment in the branches, combined with the bank’s adoption of a formal study training policy, are at odds with both empirical surveys of adults’ informal learning practices and with adults’ preferred ways of learning at work – which are predominantly informal in nature. There is also evidence that informal on-the-job learning is being displaced and crowded out by work-related formal study via the “substitution effect” (Livingstone, 2010, 424). The heavy formal study pressures are heightened by the lack of trade unions and job security, and the vulnerable position of many women workers, particularly those without higher education.
The Effects of Body Violation on the Lived Experiences of Young Women
Keywords: Embodiment
women
body
violation

The experience of one’s self as ‘living in and through the body’ has been coined embodiment. The interactions between felt inner states and interactions with one’s environment mutually construct the level and quality of this experience. Embodiment relies on a sense of safety and ownership over one’s body territory. Existing research cites the emotional, psychological,physical, and interpersonal effects of violence against women, yet the underlying disruption to body ownership that follows such violation has largely remained unidentified. Using the framework offered by the groundbreaking Developmental Theory of Embodiment, this study examines the effects of a broader spectrum of violation to body ownership than what has been examined to date. Three interviews of each of seven women, over a period of two years, provide insights into experiences of living in and with the female body as this relates to various forms of trauma.
Tee Peez, Totem Polz, and the Spectre of Indianness as Other
Keywords: Race
Indigenous people
Switzerland
self-determination
power
Foucault

The purpose of this thesis is to destabilize notions that representations of ‘Indians’ as they appear in contemporary Switzerland, Germany, and France are benign. Rather, Europeans in this region rely on ‘playing Indian’ and consuming Indianness to understand themselves as white modern subjects. I demonstrate how this operates through two case studies and argue that colonialism persists through symbolic dialectical processes between North America and Western Europe. Colonial discourse, and regimes of representation, concerning Indianness circulate across geographical locations. I link these symbolic representations to ongoing material struggles of Indigenous peoples for self-determination and land rights. Switzerland’s foreign investments and free trade with Canada for natural resources on unceded Indigenous territories implicates them in a neoliberal colonial paradigm that continues to dispossess peoples of their land. I turn to Indigenous artists and international solidarity networking as potential strategies that address both symbolic and material processes of colonization.
The Career Re-training Experience of Professional Immigrants to Canada: An Existential Perspective
Keywords: career development
new immigrants
existential psychology

New professional immigrants, who come to Canada with significant education and work experience, often find themselves underemployed after immigration. As a result, many immigrants undergo some form of re-training post-immigration. This study was a sub-study of a larger Canada Research Chair project exploring the career development and re-training experiences of new professional immigrants to Canada. This particular study focused on exploring such experiences from an existential perspective. Within a qualitative research framework, 10 semi-structured, in-depth interviews were conducted with new professional immigrants to Canada. A grounded theory approach was adopted for data analysis. Several themes emerged and key findings, including participants’ relationship with the core existential concepts of death, freedom, and meaning are introduced. Results also compare how existential considerations were related to participants’ level of career satisfaction in Canada. Results have theoretical implications for career and vocational psychology and implications for practice, including professional and self-helping.
Exploring the Influence of Optimism and Self-efficacy on New and Professional Immigrants' Retraining Experiences in Canada
Keywords: Immigrants
Retraining
Optimism
Self-Efficacy

The purpose of this study was to examine the retraining and career development experiences of new and professional immigrants in Canada. The study intended to provide an in- depth perspective into the influence of immigrants’ optimism and self-efficacy on their retraining and career development experiences. Using a qualitative methodology, in-depth interviews were conducted and a grounded theory approach was employed to analyze the data. Central themes within participant narratives emerged and key results were introduced. Participants’ experiences included a myriad of barriers and challenges, yet many viewed this experience as a positive opportunity for growth and development. The results explored differences between optimists’ and pessimists’ retraining and career development experiences, as well as the role of self-efficacy within immigrants’ career development. Results have implications for career and vocational psychology literature, practice, and career counselling, and include suggestions for future researchers.
Whose Classroom Is It? Unpacking Power and Privilege in University Women's Studies Classroom Spaces
Keywords: racism

classroom

Women’s Studies students’ accounts of their experiences academically, emotionally and politically in feminist university classrooms will be investigated in this thesis. Central to my work, through an anti-racist feminist and intersectional analysis, is to demonstrate the ways in which Women’s Studies university classroom spaces are neither ‘innocent’ nor are they devoid of racism/white supremacy as it is present in the bodies who are allowed to enter the space, voices allowed to speak and knowledge being taught. As this research is informed by a personal experience in an undergraduate Women and Gender Studies course at a local university, I will use both auto-ethnography and interviews as method in and through anti-racist feminist research methodology. Highlighting the importance of anti-racism education as a call to action in attending to this disjuncture and also to erode superficial notions of sisterhood will demonstrate white feminist supremacy as an implication for the sociology of race.
The Effects of Polo-like Kinase 4 on Cancer Cell Motility
Keywords: Plk4
motility
cancer

Polo-like kinase 4 (Plk4) has been identified as a molecular marker of resistance to therapy in cancer. Our laboratory has recently shown a motility defect in Plk4+/- murine embryonic fibroblasts (MEFs) compared to Plk4+/+. I hypothesized that Plk4 augments cancer cell motility. Plk4 depletion with siRNA in Plk4+/+ MEFs and HeLa cells suppressed invasion compared to control. Transient over-expression of Flag-Plk4 in cancer cell lines did not consistently increase invasion. However, modest Plk4 over-expression using stable clones showed higher invasion rates than non-induced. The RhoGEF Ect2, an important Plk4 substrate, transiently localized to protrusions in MEFs, suggesting a RhoA-based signalling cascade in motility. The effect of Plk4 heterozygosity on metastasis was tested in a transgenic mouse model but there was no significant difference in developing metastasis compared to wild type. Further studies are required to characterize the effect of Plk4 on motility, and its potential as a therapeutic cancer target.
A Low-power Pipeline ADC with Front-end Capacitor-sharing
Keywords: pipeline ADC
20 MS/s
10-bit
front-end capacitor-sharing

This thesis presents the design and experimental results of a low-power pipeline ADC that applies front-end capacitor-sharing. The ADC operates at 20 MS/s, resolves 1.5 bits/stage, and is implemented in IBM 0.13um technology. The purpose of the technique is to reduce power consumption in the front-end S/H. This work is a proof-of-concept and it concentrates on the front-end design. A comparison is conducted between a capacitor-sharing ADC and a regular ADC and as a result, the technique reduces the power consumption in the front-end S/H by 39%. At an input frequency of 9.53 MHz and a sampling rate of 20 MS/s, the fabricated capacitor-sharing ADC consumes 4.7 mW at 1.2 V, and it achieves an ENOB of 8.5 bits and a FOM of 0.68 pJ/step. It has an ENOB as high as 8.67 bits at 0.4 MS/s and a FOM as low as 0.6 pJ/step when sub-sampling at 20 MS/s.
Modeling and Control of a Co-axial Helicopter
Keywords: Co-Axial
Control

This thesis lays the foundations for the development of a small autonomous coaxial helicopter. This is an helicopter with two propellers mounted on the same axis and revolving in opposite directions. To steer the helicopter, this thesis proposes a mechanism that moves the helicopter’s centre of mass. Although such a mechanism has already been investigated experimentally in the literature, it has never been rigorously modeled, and a theoretical analysis has never been performed. This thesis, for the first time, presents an accurate mathematical model of the coaxial helicopter which takes into account the gyroscopic effects of the rotors, the reaction forces and torques exerted by the moving mass actuator on the helicopter body, and the fact that the inertia of the helicopter is time-varying. A nonlinear controller is rigorously derived which makes the helicopter hover at desired positions in three-space. A number of physical prototypes are discussed. None of them is capable of autonomous flight yet, but the experimental and simulation results provide reassurances that the proposed methodology is viable.
The Effect of Low Temperature on the Binding of External Chlorides
Keywords: Chloride Binding
Cement

Designing durable concrete structures is becoming increasingly important with emphasis being placed on extending service life. This project focuses on the effect of low temperatures on chloride binding, chloride binding capacity and ion-binder interactions with respect to hydroxyl ions and pH. Three supplementary cementitious materials were used as well as two w/b ratios, and four curing times. The effect of temperature cycling on chloride binding, binding capacity and ion-binder interaction were also investigated. With temperatures decreasing from 23°C to -15°C, there is a decrease in bound chloride and chloride binding capacity, with GGBFS>GU>MK>SF being the order of binding. When temperature cycling was performed, the binding capacity changed depending on the exposure temperature, with warmer temperatures associated with higher binding capacities. When service life estimates were conducted using Life-365 software, it was found chloride binding capacities determined at 23°C may not be conservative when estimating service life in colder climates.
A Medicago Sativa Draft Genome using Next Generation Sequencing Reads from Reduced Representation Libraries
Keywords: Genomic

Reduced Representation Library

Medicago sativa (Alfalfa) is an important agricultural plant for animal forage and nitrogen fixation, and has potential value in ligno-cellulosic energy production. In the quest to understand the plant, I generated a draft genome sequence of M. sativa via two reduced representation sequencing approaches: methylation-dependent filtration, and high CoT filtration. Libraries created from each approach were sequenced on an Illumina next-generation sequencing platform yielding approximately 2.5Gb of raw data. A combination of reference-based genome assembly approaches using the closely related species, Medicago truncatula as a reference, and de novo genome assembly approaches were performed to assemble the draft genome. The reference-based assembly generated 312,011 contigs with weighted median contig length (N50) of 247 bases, whereas de novo assembly produced 547,304 contigs with N50 of 275 bases. The creation of the M. sativa draft genome is vital for downstream functional analyses such as genome wide gene mining and gene expression profiling.
Valve Interstitial Cell Activation and Proliferation are Associated with Changes in Beta-catenin
Keywords: heart valve interstitial cell
beta-catenin
activation
proliferation

Heart valve interstitial cells (VICs) undergo activation and proliferation in repair and disease, but the mechanisms are not fully understood. We hypothesize that the establishment of N-cadherin/β-catenin cell-cell contacts may decrease VIC activation, and that Wnt3a/β-catenin signaling may increase VIC proliferation. VIC cultures of different densities are stained for α-SMA, cofilin, TGF-β, pSmad2/3, N-cadherin and β-catenin, and probed for phospho-β-catenin by Western blot. Low density VIC cultures are treated with exogenous Wnt3a and measured for cell number, proliferation, apoptosis, α-SMA, β-catenin, and β-catenin-mediated transcription. β-Catenin siRNA knockdown is used to assess β-catenin specificity. Increased staining of α-SMA, cofilin, TGF-β, pSmad2/3, nuclear β-catenin, and increased phospho-β-catenin are associated with few cell-cell contacts. Wnt3a increased VIC cell number, proliferation, nuclear β-catenin and β-catenin-mediated transcription without affecting activation and apoptosis, and proliferation is abolished by β-catenin siRNA. Thus, N-cadherin/β-catenin cell-cell contacts may inhibit VIC activation and Wnt3a/β-catenin signaling may increase VIC proliferation.
Slow Flow of a Viscoelastic Fluid Past a Circular Cylinder
Keywords: Fluid Mechanics
Rheology

Flow around a cylinder is important in the motion of microorganisms found in biological viscoelastic fluids that propel themselves by flagella. Flow around a cylinder experiments are difficult to perform because of the influence of the walls and ends. An approach was developed to measure the drag on a cylinder by correcting for wall and end effects. Cylinders were vertically dipped into fluids in an annular shaped tank, which was rotated to generate a flow. The force acting on a cylinder was measured using a custom force transducer. This method was used for a Newtonian fluid and two Boger fluids. The drag of the Boger fluids was several times that of an equivalent Newtonian fluid. A cavity was observed to develop behind the cylinders once the flow surpassed a critical velocity. Streakline images taken during the experiment confirmed the presence of a wake region behind the cylinders.
Structural Determinants of T Wave Alternans in Patients with Cardiomyopathy

cardiomyopathy

Structural barriers can promote discordant action potential (AP) duration alternans, T wave alternans (TWA) and tachyarrhythmia in animal hearts and simulation studies. We hypothesized that heterogeneous scar (gray zone) and dense midwall scar (midwall core) would promote TWA in patients with cardiomyopathy by slowing conduction and uncoupling transmural APs, respectively. Scar core and gray zone were quantified in 40 cardiomyopathy patients using late gadolinium enhanced cardiac magnetic resonance imaging and related to the results of a clinically validated TWA test. The percentages of gray zone, epicardial core and midwall core were greater in the +TWA group, correlated with TWA magnitude and related to a lower heart rate onset for TWA. These specific scar patterns contribute to the genesis and severity of TWA in cardiomyopathy. Greater knowledge of the substrates that promote TWA in cardiomyopathy patients is valuable in determining those at risk of lethal ventricular arrhythmias.
Effect of Yellow Pea Protein and Fibre on Short-term Food Intake, Subjective Appetite and Glycemic Response in Healthy Young Men

In order to elucidate the component(s) of yellow peas responsible for their health benefits, the effects of 10 or 20 g of isolated yellow pea protein (P10 and P20) or fibre (F10 and F20) on food intake (FI) at an ad libitum pizza meal served at 30 min (experiment 1) or 120 min (experiment 2), blood glucose (BG) and appetite in young healthy males (20-30 y) were investigated. In experiment 1, P20 suppressed FI compared to all other treatments and lowered cumulative FI (pizza meal kcal + treatment kcal) compared to F10. Protein treatments suppressed pre-meal (0-30 min) BG compared to control, whereas only P20 suppressed post-meal (50-120 min) BG. In experiment 2, there was no effect of treatment on any outcome measures. Thus, protein is the component responsible for the short-term effects of yellow peas on glycaemia and FI, but its second-meal effects diminish by 2 hours post-consumption.
Microglia Podosomes: Characterization, Ca2+ Regulation and Potential Role in Migration
Keywords: microglia
podosomes
migration
Ca2+

Microglia, immune cells of the central nervous system, activate in response to pathophysiological stimuli. One of their reactive phenotypes is to migrate to site of injury where they could have either beneficial or detrimental effects. However, little is known regarding the mechanisms underlying microglial migration and how they traverse the unique extracellular environment in brain tissue to reach their destination. Our laboratory first discovered that microglia express structures called podosomes, which can adhere to as well as degrade extracellular matrix. In this study, I further characterize microglial podosomes, and show that they associate with Iba1, Orai1 and calmodulin, proteins not yet observed in podosomes of other cell types. I also present evidence that podosome formation depends on Ca2+ and its entry through store-operated Ca2+ channels. The findings in this thesis contribute to a better understanding of podosome dynamics and their probable roles in microglia migration.
