abstract: Background: Breastfeeding self-efficacy (BSE) predicts breastfeeding outcomes in mothers of full-term infants; however, neonatal intensive care unit (NICU) practices may impede BSE and breastmilk feeding in mothers of preterm infants. Alberta Family Integrated Care (FICare) integrates parents into the care of their infant while in the NICU, by enhancing parent support, parent education and information sharing. The objective of this PhD work was to explore how Alberta FICare works to inform maternal BSE and resultant infant feeding outcomes in mothers of moderate (320/7 – 336/7 weeks) and late preterm infants (340/7 – 356/7 weeks). Methods: I conducted an explanatory sequential mixed-methods sub-study of the Alberta FICare trial. Based on BSE change scores between admission and discharge for mothers in the intervention group, I invited mothers scoring in the top or bottom quintiles to participate in interviews about infant feeding experiences in the NICU. Interviews were analyzed using inductive thematic analysis. To assess the effects of FICare on BSE and breastmilk feeding rates at discharge, I used repeated measures ANCOVA and Chi square. Finally, I used an integration matrix to integrate qualitative and quantitative findings. Results: Overall, I included 457 mothers/infant dyads (70 twins; M = 336/7 weeks gestation) from the FICare trial. Interviews with 14 mothers revealed three major themes: (a) institutional influences, (b) relationship with the pump, and (c) establishing breastfeeding. FICare was effective at improving BSE for mothers of late preterm infants, F(1, 232) = 3.97, p = .048, partial η2 = .017, but not for mothers of moderate preterm infants, F(1, 191) = 0.79, p = .375. Although exclusive breastmilk feeding rates at discharge in late preterm infants enrolled in the FICare group were higher compared to the standard care group, these differences were not statistically significant, 72.3% versus 62.2%, χ2(1) = 2.90, p = 0.089; no notable difference in exclusive breastmilk feeding was observed in moderate preterm infants. Conclusion: FICare is an effective model of care to improve BSE in mothers of late preterm infants at discharge from the NICU. More research is required to understand why FICare did not improve BSE in mothers of moderate preterm infants.

abstract: Dans ses deux demiers romans, Solo d'un revenant (2008) et L 'Ombre des choses a venir (2011 ), Kossi Efoui revient sur une des strategies narratives qui a joue un role important dans ses premiers romans (La Polka et La Fabrique de ceremonies): l'intertextualite. En effet, }'auteur, ainsi que chacun des protagonistes engages dans le recit, et meme le lecteur, recourent, de fa9on implicite ou explicite, a la memoire de leurs lectures comme voie de fusion, de reconfort et de solidarite pour affronter un passe qui peut encore hanter le present. Ce memoire se propose done de developper cette problematique de l'intertextualite dans la fiction de Solo d'un revenant et L 'Ombre des choses a venir, comme un mode specifique d'exorcisme pour faire passer la douleur du passe et la solitude du present, et postuler ainsi que l'intertextualite, dans la demarche de Kossi Efoui, fonctionne comme un exercice cathartique ou, se refugiant dans sa memoire et ses lectures, le sujet angoisse peut affronter ce qui le blesse dans le passe ainsi que dans le present. En effet, a travers le texte et ses dialogues intertextuels, telles les traces litteraires, bibliques et musicales, ainsi que l'auto-plagiat, puis par le narrateur et ses memoires et finalement chez le lecteur et ses savoirs, l'intertextualite devient un univers dans lequel lecteur, narrateur, voire protagonistes renouent avec une autre dimension d'eux-memes et participent volontiers a leur propre exorcisme.

abstract: Systemic Racism in Nineteenth-century Tales of Black Revenge highlights the shifting conception of racial oppression across France, Britain, and the USA through an investigation of stories of black or mixed-race avengers. In Histoire des deux Indes (1770), Denis Diderot wrote that “all Negroes need is a leader, valiant enough to guide them towards vengeance and massacre”. Far from viewing revenge as a private vendetta, Diderot saw revenge as a way for the oppressed black slaves to repair systemic wrong to which they were victims; to strike against the racial structure of society and establish social equilibrium. He was not alone. Many nineteenth-century writers, from Maria Edgeworth, with “The Grateful Negro” (1804), to Alexandre Dumas, with Georges (1843), imagined attempts by people of color to redress racial injustice. Yet while scholarship has examined the meaning of revenge narratives for ideas regarding black agency, it has neglected the conception of systemic racism of such tales. My thesis contributes to previous studies by filling this research gap. Drawing on narrative theory, I distinguish three different kinds of black revenge in nineteenth-century literature: (1) tales from a weak abolitionist movement, which depict systems of oppression as invincible; (2) tales from a strong abolitionist movement, which identify hidden mechanisms that sustain racial injustice, and (3) tales of a post-abolition era, which deny systemic oppression. I also shed light on cultural variations in revenge narratives, notably French works’ reluctance to support black avengers, British texts’ tendency to locate racial oppression beyond their borders and American tales’ struggle to conceptualize black collective action. This thesis thus adds nuance to previous scholarship on nineteenth-century racial tales of revenge, so far emphasizing what such narratives have in common: an apparent desire to silence the political motives of black agency.

abstract: Cranial radiotherapy (CRT) is an important and effective treatment for childhood brain cancers, but is also strongly associated with persistent neurocognitive decline, a heightened risk of secondary radiation-induced malignancies and altered white matter developmental trajectory. These late effects of CRT increase in severity the younger a patient is treated. Despite substantial advances in radiotherapy planning and treatment, late effects remain an issue to the ever-increasing group of childhood cancer survivors. The cellular and molecular mechanisms of these late effects are largely unknown, and the subtleties of how a developing, pediatric brain interacts with the ionizing radiation (IR) requires further investigation. This study aimed to characterize how distinct neural lineages present in a developing brain respond to IR, and how these cells repair DNA damage incurred by IR. Cells of the oligodendrocyte lineage, and particularly, oligodendrocyte progenitor cells (OPCs), exhibit marked radiosensitivity relative to other neural cell types, both post-mitotic and replicative. These OPCs are sensitive to a single dose of IR as low as 0.25 Gy, and display impaired DNA double-strand break (DSB) repair kinetics with a high baseline level of accumulated DSBs. While high in reactive oxygen species, modulation of the oxidative stress levels of OPCs is ineffective in rescuing radiosensitivity or DSB levels at rest. Interestingly, OPCs are profoundly sensitive to small molecules that compromise replication fork stability, and have other indicators consistent with aberrant collapsed replication fork processing and repair. Though the reason for this replication phenomenon remains elusive, it may be related to a baseline difficulty engaging HR-directed fork repair and restart mechanisms. Altogether, these data provide cellular mechanisms for the sensitivity of the developing brain to IR. Highly radiosensitive OPCs, more abundant and proliferative in the pediatric brain, might be ablated by IR at a young age. This may contribute in part to the clinical late effects of pediatric cranial radiotherapy. Further understanding of this sensitive cell type might provide an opportunity to protect the developing brain from IR, decrease the severity of late effects of childhood CRT, and provide the safest, most effective treatment for childhood brain cancers.

abstract: This thesis explores how certain entrepreneurial skills and knowledge are transmitted to Trinidadian youth through family and educational programs. On one hand, government initiatives direct unemployed youth back into the labour market through entrepreneurship education. On the other hand, many youth attending these institutions are already employed, and have pre-existing businesses. This invites reflection on how youth are learning about entrepreneurship outside of formal training, and why they are choosing to pursue formal training anyway. Based on ethnographic fieldwork in Trinidad, this thesis demonstrates that young entrepreneurs engage in both the measured pursuit of profit and the fulfillment of other culturally meaningful desires, and that these internal motivations are influenced by external sources of knowledge and social interactions. Drawing on the literature on economic anthropology, I agree that youth are learning about entrepreneurship from families, and argue that such learning can be effectively supported via public policy and educational institutions.

Chapter 1 contains basic definitions and results which are used in the subsequent chapters. In particular, it includes a fairly detailed account of tensor products of modules and torsion free abelian groups of rank one. Chapter 2 is devoted to the discussion of the endomorphism algebra of a finite dimensional vector space with a finite set of invariant subspaces which satisfy certain distributivity conditions. Among other results we have established original theorems (2.1) and (2.3). Chapter 3 contains· the discussion of Brenner's five-space theorem (see [4]). Finally in Chapter 4, Brenner and Butler's theorem (see [5]), which proves the existence of a certain class of torsion free abelian groups, is established.

abstract: Energy consumption and delay are the key factors influencing users' quality of experience for applications running on wireless devices. In cellular networks, providing a satisfactory user  experience faces several challenges caused by the poor interactions between multiple factors. First, cellular networks suffer from long round trip times and also employ a radio resource control protocol, which keeps the radio of the device in high power state even after completion of a data transfer. Second, in most applications, completing a user action involves many round trips over the high-latency cellular link, which can lead to poor application performance. Moreover, periodic and intermittent traffic pattern exhibited by the majority of applications can result in serious energy inefficiencies. In this thesis, we address these challenges from the network and end device perspectives. First, we design a network-centric solution, called WebPro, that adopts speculative loading and bundling techniques to reduce latency and energy consumption of mobile web browsing. Performance evaluation results obtained through live experiments indicate that WebPro outperforms state-of-the-art, though the degree of improvement varies for different webpages. Then, we focus on energy-delay tradeoff on end devices and design algorithms to balance the energy-delay tradeoff inherent in bundling. Specifically, we formulate a generalized notion of bundling as an online optimization problem. The objective of this problem is to minimize the bundling cost defined as a weighted summation of energy and delay costs. Based on two different energy cost models associated with smartphones and internet of things (IoT) devices, we develop online algorithms to solve the optimization problem. A distinctive feature of our online algorithms is that they do not rely on any assumption about the traffic pattern or nature of applications. We provide theoretical performance bounds for our proposed algorithms by comparing them to an optimal offline algorithm. We evaluate the performance of our algorithms in a range of realistic scenarios using both model-driven simulations and real experiments on a smartphone. Our results show that depending on the delay tolerance level of a user, energy savings ranging from zero to about 100% can be achieved using our algorithms.

abstract: Developing a usable Application Programming Interface (API) is a complex and expensive task. Two major factors play important roles on the usability of an API: its design and the resources made available by designer (e.g. documentation, tutorials). Typically, developers evaluate the usability of an API after implementation, resulting in refactoring tasks that could be avoided if this evaluation were continuously conducted. This thesis explores a process for building usable APIs that combines concepts from an API usability evaluation method (Cognitive Dimensions) and an Agile development methodology (eXtreme Programming). Explored effectiveness of this process and the impact of different resources on usability, I implemented a web-based API and conducted a user study. Results from these two evaluations indicated that: the process was effective to design the API, but ignored some concerns around the resources; and usability was improved when functional examples with source code are provided.

abstract: Canada has a long tradition as an immigrant-receiving country. Women who have recently immigrated to Canada contribute significantly to Canadian population growth, first by migrating to Canada, and second, by bearing children soon after arrival to Canada. Considering the crucial role that women who immigrate contribute towards the population growth of Canada, understanding her pregnancy health needs is of national importance. Surprisingly, there remains a conspicuous knowledge gap in understanding immigrant women’s experiences in pregnancy, in particular, in understanding her experiences establishing pregnancy supports. The aim in conducting this study was to address the current knowledge gap in relation to pregnancy experiences of newcomers to Canada who identify with a non-European ethnic group by identifying (a) facilitative strategies used in primary support formation, (b) the barriers to forming primary supports in Canada and, (c) what supports participants would have wanted but were unavailable to them at the time. Individual in-depth qualitative interviews were conducted with 13 participants using the Enhanced Critical Incident Technique (Butterfield, Borgen, Amundson, & Maglio, 2005). Findings from this study identified systemic barriers to forming pregnancy support networks such as acculturation issues, difficulty accessing information, language barriers, inadequate information on supports available, financial barriers, difficulty accessing maternity leave benefits, and not perceiving adequate attention from health care providers. There were also several factors identified as helpful in pregnancy support formation such as the support of their partner, persistence advocating for pregnancy care needs, pregnancy apps, community programs offering pregnancy supports for newcomers, doctors who showed concern, and mental health care services. Participants identified wanting access to information about supports that they thought would have been helpful but were not available to them at the time. This research informs primary healthcare providers about the social, psychological, and economic factors that contribute to primary support formation during pregnancy as well as specific considerations faced by newcomers to Canada. Findings from this study not only inform interventions specific to newcomers to Canada, many of the findings have elucidated barriers to primary support formations shared by pregnant women, regardless of her country of origin.

abstract: A variant of streptavidin, SAVSBPM32, was previously designed to incorporate mutations that weaken binding to biotin and introduce a cysteine at position 86. Streptavidin-binding peptides have also been re-designed to test the binding capabilities of SAVSBPM32. The primary goal of this project was to crystallize SAVSBPM32 and evaluate its interactions with biotin, a cysteine containing SBP-Tag and a cysteine containing a biotinylation tag (CPFB-2). The crystal structure of SAVSBPM32 in complex with biotin revealed for the first time that the loop bridging the third and fourth b-strands in SAVSBPM32 can adopt a closed or an open conformation. The crystal structure of SAVSBPM32 in complex with CPFB-2 reveals the novel structure of a biotinylated peptide bound to streptavidin while also forming a disulphide bond. These findings confirm key design principles and suggest approaches for further development.

abstract:
The smallest unit of the Philippine Catholic Church is the Basic Ecclesial Community (BEC), a group of families who come together for worship, bible study and reflection on their social circumstances. In many dioceses BECs are encouraged to move beyond mere reflection and act as agents of change, organizing cooperatively for meaningful and peaceful development. A significant corpus of literature has developed around the concept, and it emphasizes the power of small groups to effect change, and the power of a national network of BECs.
In many respects the discourse of development through BECs resembles an ideal postdevelopment scenario but, as numerous commentators have explained, postdevelopment is unachievable due to a myriad of structural pressures pushing on any group. In the Philippines the material reality of poverty and powerlessness stands in the way of most BECs that seek development.
One field season was spent in the Diocese of San Carlos, known nationally for its vigorous development thrust. Qualitative research methods, including in-depth interviews, conversation and participant observation, were employed. The ideal picture framed by the literature on BECs is measured against the reality of development in the rural countryside. Conclusions demonstrate a micro-managed series of programs orchestrated at the Diocese-level, and little semblance of self-sustainable grassroots development at the BEC level.

abstract: Obstructive sleep apnea (OSA) is a common sleep disorder that has been identified as an independent risk factor for the development of cardiovascular and cerebrovascular disease. OSA-induced intermittent hypoxia (IH) has been shown to be the principal mediator of vascular disease, however the specific pathophysiological mechanisms through which IH impacts human physiology is not fully understood. Individuals with OSA have been shown to have impaired cerebral autoregulation (CA), which may be a possible mechanism leading to OSA being an independent risk factor for stroke, however no studies have directly investigated how IH impacts dynamic CA. In addition, the impact of IH on human physiology has been predominately investigated during wakefulness, while individuals with OSA are exposed to IH during sleep. Therefore, the focus of the thesis was to investigate the impact of nocturnal IH on CA in healthy humans, in an effort to further understand the mechanisms by which IH disrupts physiology. The pilot study conducted in this thesis was performed as a secondary data analysis to investigate the effectiveness of the dynamic CA in healthy humans, during the transition from wakefulness to sleep, during one night of nocturnal IH exposure and during acute IH vs prolonged IH exposure, using data previously published (1). The novel findings from this study demonstrated that the dynamic CA effectiveness was similar during non-rapid eye movement (NREM) stage 2/3 sleep as compared to wakefulness; however, the reported decrease in the variability of VP and MAP oscillations during NREM stage 2/3 may help explain why the prevalence of stroke is lower during the first half of sleep. In addition, one night of nocturnal IH exposure does not impair dynamic CA and prolonged nocturnal IH exposure may not impact dynamic CA differently than acute nocturnal IH exposure.

abstract: Unlike the traditional teacher/instructor-centered approach, Learner-Centered Assessment (LCA) promotes students’ active learning that occurs according to the needs of the 21st-century society. The process of creating LCA is not a ready-made solution, making it possible to develop a unique, inclusive model that could be implemented with the same success in different education settings. Research has shown that LCA makes student learning more meaningful by being applied through discovery, creative, and inductive approaches. It enables independent work of learners to be more apparent and better represented and focused on individualization and individual gains. Using LCA, students in undergraduate business programs are expected to develop the following entrepreneurial skills: dynamic strategies, research, creativity, and an entrepreneurial mindset (e.g., the ability to recognize an entrepreneurial culture and effectively manage a team). The characteristics of LCA have been recognized to go above the definition and conceptual delimitation of standardized testing and rote learning. Using LCA, a balanced approach to teaching and learning the necessary 21st-century entrepreneurial skills and recognizing the responsibility of being the mediator of the LCA approach can be manifested through innovative instructional strategies involving the use of technology. In my study of the role of LCA in the development of undergraduate students’ entrepreneurship through the redesign of learning tasks in a course, the mixed methods research design guided my data collection using pre- and post-LCA questionnaires, one-on-on interviews, and observations. The data enabled me to answer research questions pertaining to undergraduate business students’ perceptions of the value of LCA on developing their entrepreneurial knowledge, skills, and mindset, as well as their learning experiences of LCA in the course and the affordances and challenges of incorporating the use of technology into LCA.

abstract: The purpose of this study was to examine the relationships among postpartum depression at 4 months of age, feeding practices and child growth at age 2 years. This study used data from 1881 mothers participating in the All Our Babies Study in Calgary. The mothers participated in five surveys between 24 weeks gestation and 2 years of child age. Multivariable regression analysis was done. Postpartum depression was negatively related to exclusive breastfeeding duration (β = -2.30 weeks, 95% CI: -4.39, -0.22). Postpartum depression and feeding practices were unrelated to child growth at age 2 years. We found mothers with postpartum depression at 4 months terminated exclusive breastfeeding earlier (2.3 weeks) than mothers without postpartum depression whose average exclusive breastfeeding duration was 20.2 weeks. The findings suggest a need for breastfeeding support for mothers with postpartum depression to sustain breastfeeding to the recommended duration.

abstract:
The ability to predict propagation of electromagnetic waves through matter is of great importance in various industries, that include medicine, food, geophysics, oil and gas and
others. Polarizability and conductance, that may also be referred to as dielectric permittivity and electric conductivity, are the two most important properties that govern this phenomenon. These basic properties often depend on frequency of the excitation field, water content, concentrations of charged species, spatial distribution of inclusions and their sizes, surface charge etc. There has been an abundance of dielectric property measurements of various physicochemical systems reported in the literature. However, there has been a lack of measurements reported that would concern isolation of an electrode polarization effect, which manifests itself in a build up of charged species near electrodes at low frequencies. Also, there has been a shortage of studies performed in dynamic systems, that involve measurements of reflection and transmission scatter parameters, and dielectric properties at radio frequencies during immiscible displacement floods in porous media.
Frequency broadband impedance measurements of 9 ferroelectric and magnetic nanosuspensions were performed. Relative dielectric constant and conductivity frequency spectra were extracted using a parallel resistor-capacitor equivalent circuit. Tikhonov’s regularization was used to fit the extracted dielectric spectra by the continuous relaxation Kramer-Krönig model. The electrode polarization effect was removed by zeroing out the two slowest peaks in the resulting time domain relaxation amplitude responses. The effective medium theory, the Gouy-Chapman-Stern-Graham model and zeta-potential measurements were used to validate the proposed electrode polarization removal method.
Water saturation axial profiles and dielectric properties were monitored via electromagnetic sweeps during oil and water floods of confined sands. Breakthrough of advancing and trailing fronts and in-situ emulsification were captured during the imbibition (water) floods. Pressure distributions along sand packs and dynamic capillary pressure curves were calculated for some drainage and imbibition floods. Series, parallel and semi-disperse mixing models were fitted to the extracted dielectric spectra.
In the present work, several applications of the novel electromagnetic sensing method have been demonstrated to dynamically monitor dielectric properties in nanosuspensions and their spatial distributions during immiscible displacements through saturated confined sand packs.

abstract: Little is known about the progression of chronic kidney disease (CKD) during the emerging adulthood period in patients with pediatric onset CKD cared for in primary care. We performed a retrospective cohort study using administrative data from The Health Improvement Network Database to determine the natural history of CKD, the impact of the emerging adulthood period, and the effects of comorbidities including mental health disorders, substance use, and pregnancy on CKD progression. We identified 15,679 patients who met cohort inclusion criteria. We found that kidney function measured using the estimated glomerular filtration rate (eGFR) increased with increasing age. Emerging adulthood was associated with an attenuation in this increase in eGFR. Finally, the presence of mental health disorders, substance use, and pregnancy modified the relationship between age and eGFR resulting in a small, but statistically significant acceleration in the eGFR increase over age, but were associated with lower baseline eGFR.

abstract:
Acoustic seismic impedance inversion is investigated using a migrated, stacked, reflectivity image.  Basic inversion formulae are derived and sensitivity to the bandwidth of the reflectivity is analyzed.  It is shown that high frequencies are responsible for the detail in the impedance image and low frequencies are responsible for the trend, where the low frequencies must be acquired from an external data type.
External data must be matched to the reflectivity image.  Methods for data amplitude balancing and phase rotation are discussed.  A Hilbert envelope calibration algorithm is designed to calibrate the time-depth curves between the seismic reflectivity and the external data.  Both the use of well logs and stacking impedances are explored, and while well logs produce the most accurate images, a combination of the two types is also acceptable.  Inversions are sensitive to the amount of external data that is added and reliable impedance images can be produced by using just 1.5-2.5 Hz of the external data.

abstract:
The increasing implementation of mini and microchannels in industrial or biomedical applications is a source of novel challenges for pressure drop. Pressure loss due to surface roughness for flows in microchannels is reported to deviate from conventional macroscale theory in both the laminar and turbulent regime even for small relative roughness (less than 5% of the hydraulic diameter).
This work aims to characterize the influence of the geometry parameters of Q-type structured surface roughness on the hydraulic performance in two-dimensional rectangular channels under steady laminar flow. The surface roughness is modeled as spatially periodic rectangular elements, which is commonly used for micro heat exchangers. Computational Fluid Dynamics (CFD) is used to solve the governing continuity and momentum equations. The selected roughness parameters are typical for industrial microdevices (e.g. micro heat exchangers) and biomedical systems.
It is shown that the pressure drop is larger in both mini and microchannels when compared to conventional channels for relative roughness less than 5%. Different flow regimes are identified. A novel correlation between pressure drop and roughness characteristics is developed. Predictions are compared to the available literature for similar roughness configuration and results show good agreement. Although the proposed correlation is defined for Q-type structured roughness, the predictions are of acceptable accuracy for other roughness geometries.
The results led to the proposal of a simplified approach for modeling the influence of distributed surface roughness on bulk flow parameters through a prescription of boundary condition on the rough wall for laminar and steady duct flows. This approach promises to predict the averaged velocity profile above the roughness amplitude without detailing flow behavior near the rough wall.

This doctoral thesis develops theory to explain how landholders secure their land and land transactions and why they use or do not use land registration and off-register land-securing strategies in urban and peri-urban Accra, the capital city of Ghana.
This study argues that without understanding the underlying reasons why landholders choose to use land registration systems or off-register strategies to secure their land, it is difficult to target aspects of the land registration system to improve; nor can feasible alternative(s) be developed. Using semi-structured interviews, data for the research include a total of 81 interviews, a workshop and two focus-group discussions from Oyibi and Dansoman which are, respectively, urban and peri-urban communities in Accra. The data collected is analyzed using a land-securing theoretical framework developed in the context of the on-going changes in the land tenure system, drawing upon the Reasoned Action Approach, Technology Acceptance Model, and a Social Change Model. The study revealed the predominant mode of land-securing behaviour follows a waterfall or staircase trajectory, where land-securing behaviours are determined by perceptions of tenure security and escalated in response to the perceived nature of threat to their claim. The theory that emerged from the analysis holds that landholders evaluate many inter-related causal factors that are dialectical and mutually inclusive when choosing a land-securing strategy. In a socially, politically, and economically precarious environment where tenure is highly insecure and entrepreneurial and exploitative activities abound, landholders evaluate their personal beliefs about consequential outcomes, usefulness, accessibility, and ease of use, together with societal norms, and associated factors which they believe could hinder or facilitate the performance of the land-securing behaviour. Additionally, landholders also evaluate the degree of security of their tenure or transactions and the level of threat they face.
This research deepens understanding of land registration usage through the development of theories that explain why landholders do not use land registration in securing land in urban and peri-urban Accra, by constructing a waterfall and staircase model for explaining land-securing strategy usage. Results from the study are useful for improving current (or developing alternative) approaches for securing land rights in Ghana.

abstract: Children with Attention-Deficit/Hyperactivity Disorder (ADHD) face significantly increased risk for poor outcomes across domains; however, not all children with ADHD experience poor outcomes (Lee et al., 2008; Owens et al., 2009).  Resilience perspectives can provide a valuable avenue through which to explore the factors and processes contributing to more positive trajectories among children with ADHD.  The current study took a resilience approach to investigate the role of a potential protective factor, perceived social support, in promoting emotional well-being among children with ADHD.  Social support has long been recognized as an important factor in promoting well-being among both typically-developing and at-risk populations (e.g., Cohen & Wills, 1985; Demaray et al., 2005), but has yet to be explored in this capacity within the ADHD population.  This study specifically examined how school-age children with ADHD perceive support from key individuals in their lives (e.g., parents, teachers, peers, other adults) and the relationships between perceived social support and various indicators of emotional well-being (internalizing problems, self-concept).  Additionally, main versus buffering models of social support were explored by evaluating the relationships of social support and emotional adjustment in the context of lower or higher social preference status.  A total of 55 children ages 8 to 11 with ADHD-C or ADHD-HI and their parents participated in this study.  Overall, results indicate positive and moderate associations between perceived social support and several aspects of self-concept, with parent and classmate support most consistently associated with these outcomes.  Results further support a main effect model of perceived social support, with no interaction detected between social support and social preference status.  Results of this study are discussed within the context of applying a resilience lens to the study of ADHD, and implications for both research and practice are discussed.

abstract: Since the failure of the Charlottetown Accord, there is a widely accepted assumption that constitutional politics has ended. However, given the intensity of constitutional pressures preceding the Charlottetown Accord, it is unlikely that the actors involved would give up their constitutional ambitions. A more reasonable plausible is that these groups would seek out alternative forums to provide them with similar constitutional resources. As such, while macro-constitutional politics (formal amendments) was abandoned, through the processes of micro-constitutional politics Gudicial litigation) and quiet-constitutional politics (federal-provincial agreements and political conventions), the constitutional landscape of Canada has experienced widespread change. These changes are consistent with demands articulated by constitutional actors in the Charlottetown Accord. The post-Charlottetown decade, therefore, is more accurately characterized as a decade of alternative constitutional politics, rather than a decade without constitutional politics.

abstract:
Carbon Capture and Storage is one of the proposed technologies to reduce anthropogenic carbon dioxide emissions. One of the concerns about the feasibility and safety of this technology
is the possible atmospheric leakage of CO2 from geological storage sites. Leakage may intercept shallow aquifers, surface body waters, and escape to the atmosphere, which can be hazardous to both ecosystems and human health.
A system was developed in this study for sampling plumes of CO2 and determining whether they are likely to be from a CO2 storage site. Since atmospheric CO2 levels naturally fluctuate due to photosynthesis, respiration, biomass and fossil fuel combustion, elevations in CO2 concentration do not necessarily represent a leakage. It is possible to differentiate between different sources of CO2 by looking at the ratio of O2 depletion to CO2 elevation of
a plume relative to the background air (dO2/dCO2). A gas analysis system was used to measure differentials in CO2 and O2 concentrations for different plume samples relative to background air.
The CALPUFF dispersion model was used to estimate the location and maximum concentration levels of CO2 in the atmosphere. Then a CO2 leakage from a storage site was simulated by release of pure CO2 with emission rate of about 100 L/min for seven hours at a
measurement site. The dO2/dCO2 of the plume samples were measured relative to background air collected at the site. Measured absolute values of  dO2/dCO2 for plume samples from pure CO2 emissions (0.23 - 0.31) were significantly different from the measured values for plume samples from combustion of different types of carbon based fuels (1.06 - 1.97).

abstract: Hot-wire chemical vapor deposition (HWCVD) is a new and promising technique to fabricate device quality thin films. It is believed that gas-phase reactions play an important role in the deposition of high quality films. In this work, three alkylsilane molecules, namely tetramethylsilane (TMS), trimethylsilane, and hexamethyldisilane (HMDS), were used as single source gases in a HWCVD reactor for SiC film deposition. 118 nm vacuum ultraviolet (VUV) laser single photon ionization (SPI) coupled with time-of-flight (TOF) mass spectrometry were used to study the decomposition products of all three molecules on the hot filament made of tungsten or tantalum under collisionfree conditions and subsequent gas-phase reaction products formed in a HWCVD reactor. It is found that alkylsilane molecules decompose to radicals on the hot filament. Methyl radicals are produced from all three molecules studied. Hydrogen abstraction reactions between the methyl radical and the abundant parent molecules produce more radicals in the HWCVD reactor. Subsequent biradical combination reactions constitute the main secondary gas-phase reaction pathways, resulting in the formation of many alkylsubstituted silanes and silyl-substituted alkanes. In addition, it is believed that several disilacyclobutane compounds have been produced through the cycloaddition of the unsaturated silene intermediates. This provides strong evidence for the existence of the reactive silene species in the reactor. The Si-C bond is found to be the major bond connection in the gas phase reaction products. With Si-Si bonds in HMDS and Si-H bonds in trimethylsilane, more Si-Si bond connections are present in the backbone of the high mass reaction products. Due to the existence of both Si-Hand C-H bonds in trimethylsilane, experiments with its isotopomer, (CH3) 3 SiD, have demonstrated that two H-abstraction reactions exist between CH3 radical and the parent molecule, yielding two secondary radicals with the same mass. This leads to the observation that trimethylsilane has the most complicated gas phase chemistry of the three molecules studied. A study of the effect of TMS partial pressure has shown that source gas decomposition on the filament and secondary gas-phase reactions become less efficient with a decrease in the source gas pressure in the reactor. The experiments with TMS using both W and Ta filaments indicate that the filament material does not affect the decomposition pathway of source gas on the filament. Results with a 0.25% TMS in He mixture suggest that Ta may have a slightly better catalytic capability than W in decomposing TMS.

abstract: This thesis will be an investigation of the relationship between myth and history as it figures in religion in the construction of "feminine" types. While myth and history have been considered separate entities in much contemporary theory and scholarship, this thesis will show that this perceived separation is a relatively modern distinction and that in religion an overlap has often occurred. Such an "intertwining" of myth and history has been an integral part of hagiography and other attempts to provide exemplars or models of ideal types. Two instances of such intertwining are examined: the hagiographical text of Mary of Egypt and the Goddess as she has been presented and constructed by Carol P. Christ. This study demonstrates that in the creation and presentation of such "feminine" figures an imaginative process is employed. This imaginative process draws on elements from both history and myth in order to present a purposefully constructed figure. The work of Paul Ricoeur will be examined in order to help establish the basis of this appeal to imagination and the proposal is made that Ricoeur's hermeneutics of suspicion provides a means of understanding such an imaginative process as well as the extremes that can occur when engaged in this imaginative process.

abstract: Integrative and conjugative elements (ICEs) are autonomous-transferred mobile genetic elements that play a significant role in disseminating antimicrobials between bacteria via horizontal gene transfer (HGT). One recently identified ICE in a clinical isolate of H. somni named ICEHs02 is 72,914 base pairs in length and harbours seven AMR genes which confer resistance to tetracycline (tetR-tet(H)), florfenicol (floR), sulfonamide (sul2), aminoglycoside (APH(3'')-Ib), (APH(6)-Id), and (APH(3')-Ia), and copper (mco). This study investigated the host range of ICEHs02, assessed the effect of antimicrobial stressors on transfer frequency of ICEHs02, and examined effects of ICE acquisition on the host. In vitro conjugation assays were conducted to examine the frequency of transfer of ICEHs02 into other bacteria. PCR and sequence analysis confirmed the presence of ICEHs02 and its circular intermediate in recipient strains. The susceptibility of ICEHs02-carrying recipients was conducted using broth microdilution. The effect of tetracycline and ciprofloxacin on transfer frequency and excision rates was investigated using mating assays and qPCR. Growth curves and competition experiments were conducted to assess the fitness cost of ICEHs02 on the host. ICEHs02 was observed to transfer into H. somni and Pasteurella multocida. PCR assays confirmed the presence of the circular intermediate, ICE-associated core genes and accessory genes in recipient strains. Susceptibility testing confirmed the function of ICEHs02-associated AMR genes in recipient strains. Tetracycline and ciprofloxacin induction significantly increased the transfer rates of ICEHs02. The copy numbers of the circular intermediate of ICEHs02 per chromosome exhibited significant increases of ~ 37-fold after tetracycline exposure, and ~ 4-fold after ciprofloxacin treatment. The acquisition of ICEHs02 reduced the relative fitness of H. somni TG by 28% (w = 0.72 ± 0.04) and P. multocida TG relative fitness was decreased by 15% (w = 0.85 ± 0.01). In conclusion, this study provided information on the host range of the multi-drug resistant ICEHs02, gave insight into the regulatory role of antibiotics on the HGT of ICEs and emphasized the importance of ICEs in the dissemination of AMR between bacteria.

abstract:
Centroid moment tensor (CMT) parameters of earthquakes are routinely estimated to gain information on structures and regional tectonics. However, for small earthquakes (M<4) it is still challenging to determine CMTs due to the lack of high-quality waveform data. In this study, we propose to improve solutions for small earthquakes by incorporating multiple seismic data types in Bayesian joint inversion: polarities picked on broadband signals, amplitude spectra for intermediate frequency bands (0.2--2.0 Hz), and waveforms at low frequencies (0.05--0.2 Hz). Both measurement and theory errors are accounted for by iterative estimation of non-Toeplitz covariance matrices, allowing to objectively determine weights for the different data types in the joint parameter estimation. Validity and applicability of the method are demonstrated on simulation and field data. Results demonstrate that the combination of data, such as a single high quality waveform, a few amplitude spectra and many waveform polarities are able to resolve CMT parameters to comparable quality as if many high quality waveforms were available.

Results of 10 induced events that occurred in northeastern British Columbia between January 2020 and February 2022 indicate predominant strike slip focal mechanisms with low non double-couple components. These events appear to be located at shallow depth with a short duration as expected for induced seismicity. These results are consistent with previous studies. Therefore, we learn that this method reduces the dependency of source inversion on high-quality waveforms and permits to resolve CMTs for earthquakes as small as ML 1.6.

abstract:
Ethylene is a very important feedstock widely used for manufacture of polymers and solvents in modem chemical industry. Commercially ethylene is produced by steam cracking of ethane or naphtha. This process is highly endothermic and relies on the combustion of methane to satisfy its large energy demand. The consumption of methane is a growing concern. Environmentally, it is another source of CO2 emission. Economically, the rising prices of methane will result in loss of profitability of the plants. Consequently, production of ethylene by oxidative dehydrogenation (ODH) of ethane, an exothermic or mild endothermic reaction using either 02 or sulfur as oxidizing agent, has been widely investigated as an attractive alternative to the steam cracking process.
The objective of this thesis is to study the chemistry of ODH of ethane with H2S/O2 combined or elemental sulfur alone as oxidant, and to establish a process that effectively produces ethylene at low energy cost. A series of studies were conducted with feed mixtures of C2HdO2/N2, C2HdH2S/O2/N2 and C2H6/S2/N2 using a tubular reactor in the temperature regime 700 - 850°C over residence time of 0.1 to 3.0 s. Quantitative product analyses were perfonned using GC and GC-MS technology with N2 as internal standard.
For C2H6/O2/N2 system, ethylene yield was observed to be a function of the reaction conditions (temperature-residence time) and the feed composition. Feed composition had a great influence on ethylene formation with low C2H6/O2 ratio or high ethane partial pressure resulting in decreased ethylene selectivity and yield. The highest ethylene yield for gas phase ethane ODH was obtained using C2H6/O2 ratios from 2 to 4, at temperatures of 750 - 850°C with residence time from 3.0 s to 0.5 s for the low and high temperatures conditions respectively. However, the maximum ethylene selectivity obtained at given ethane conversions were lower than the value calculated for the steam cracking using empirically - based forn1ulae.
The addition of H2S increased the selectivity to ethylene in the ODH of ethane. Overall, the maximum ethylene selectivity displayed an average ~20% increase at a given ethane conversion in the 40% to 80% range. Using a mixture of C2H6/H2 S/02/N2 at ratio of
40/10/10/30 over residence time of 0.5 s, selectivity of ethylene up to 90 % with conversion above 70% was obtained at 800°C. Examination of individual H2S/02 and S2/C2H6 reactions confirmed a two step mechanism consisting of initial oxidation ofH2S to sulfur species and oxidation of ethane to ethylene with re-formation of H2S.
Elemental sulfur was observed to oxidize ethane to ethylene with high selectivity. Using a feed composition of C2H6/S2/H2S/N2 at ratio of 60/5/22/13, an ethylene selectivity up to 89% was obtained at ethane conversion of 84% at 850°C over 0.6 s. H2S appeared to be an effective dilutant for this sulfur/ethane reaction. The ethylene yield obtained with direct sulfur/ethane reaction exceeds that when obtained using a conventional steam cracking process. Reaction mechanisms are proposed to explain the results. The study on ethane/sulfur reaction presents the interesting possibility of designing an industrial process in which ethylene is co-generated in major sour gas processing facilities or refineries at a lower energy cost by utilizing sulfur and the waste heat from the Claus process.

abstract: Online support staff workers perfom1 essential services for equipping instructors and students to participate in web-based courses. However, very few studies have either focused exclusively on this staff, or provided excerpts of their own thoughts about their work. This study describes four support staff workers' services for web-based course delivery at a Western Canadian college, and the conditions that support and challenge the staff in their work. The data collection emerged from personal interviews augmented by two observations and a review of relevant college documents. The study revealed that this staff adds extensive value to online course delivery by laying the groundwork for course participants, maintaining a quality learning environment, and preparing for the future of e-leaming. The study further demonstrated that collaboration, support from others, reliable technology and the intrinsic fulfillment of work benefited the staff immensely. Finally, the study revealed that inadequately shared work, uncertainty over funding, performance of sudden and time-consuming tasks, and confusion over boundaries ofresponsibility were challenging to the staffs efforts.

abstract: This dissertation presents theoretical analyses and numerical experiments on buoyancy-driven convection in porous media in the context of geological storage of carbon dioxide (CO2) in deep saline aquifers. One of the main focuses of this study is to investigate the role of the concentration dependent base state density profile in the stability criterion of buoyancy-driven convection and hydrodynamics of the associated convective mixing in different fluid systems. In particular, scaling relations, which allow estimation of the onset of the convective instabilities and the generalization of the base state density dependence of the growth of the instabilities are of interest. Stability criterion of the buoyancy-driven convection in analogue fluid mixtures used in experimental studies of CO2 convective mixing are of particular interest. The density profile dependence of the growth of instabilities in both binary and ternary fluid mixtures is mathematically analyzed and scaling relations that relate the stability criterion of the diffusive boundary layer to the key parameters of the systems is proposed. It is shown that the characteristic behaviour of the base state density profile plays an important role in stability characteristics of the diffusive boundary layer and convective mixing beyond the onset of instability. The results have shown that the choice of an analogue system is critically important in correct representation of the onset of convective instabilities of CO2/water and design of experiments. In particular, it is shown that there are fundamental differences in the evolution of the buoyancy-driven instability and dynamics of convective mixing between CO2/water and typical EG-MeOH/water and PPG/water analogue systems. The developed concepts on the role of density profiles in the stability criterion of the buoyancy-driven convection are applied to multi-component fluid systems with applications to impure CO2 storage. The role of permitted impurities on the characteristic shape of the density profile evolved during the dissolution of impure CO2 in water is mathematically analyzed and a parameter space classification, which allows prediction of general stability behaviour of an impure CO2/water system is proposed. Specifically, a linear stability analysis is conducted to investigate the effect of H2S impurity in CO2 stream on the onset of buoyancy-driven convection associated with impure carbon CO2 storage in deep saline aquifers. Contrary to the common belief, it is shown that an impurity such as H2S has the potential to accelerate the buoyancy-driven instabilities. The theoretical analysis is extended, by means of high-resolution numerical simulations, to characterize the long-term behaviour of density-driven convection and the associated mixing. The key features of the convective dissolution beyond the onset is analyzed by evaluating the finger patterns and convective fluxes at different periods of the mixing process. It is shown that an impure CO2 stream may lead to different convective mixing dynamics at early and late periods of dissolution process depending on the fractional composition of the permitted impurity. Another focus of this study is to develop mathematical models that capture key features of fluid flow and transport in fractured porous media and to characterize the stability criteria of buoyancy-driven convection in fractured aquifers in the context of CO2 storage. Through performing a parametric analysis, by means of a linear stability analysis, the role of physical properties of a fracture network in the stability of the diffusive boundary layer in a saturated fractured porous medium is characterized. Important effects of fracture interporosity flow and fracture storativity on the stability behaviour of the system are demonstrated and scaling relations that can be used to estimate the onset of density-driven instabilities in a dual porosity porous system are reported as a function of the most common physical properties of the fractured porous medium. These findings improve our understanding of density-driven flow in porous media in the context of CO2 storage and are important in the estimation of potential storage capacity, risk assessment, and storage site characterization and screening.

abstract: The reaction of natural organic matter (NOM) with chlorine results in formation of disinfection by products (DBPs), known carcinogens. Fulvic acid (FA), a key component of NOM is likely a precursor to DBPs. Photocatalytic advanced oxidation using TiO2 is efficient under UV irradiation and known to degrade humics with reduction of DBPs. However, TiO2 may be dye “sensitized” for visible light, where the dye excited state transfers an electron to TiO2 conduction band. NOM adsorbs on the surface of TiO2 and sensitizes (“self-sensitization”). NOM undergoes an initial oxidative step upon visible light absorption and transfers an electron to the TiO2 conduction band. Oxygen captures the electron, forming superoxide which can aid in degradation of NOM. Model studies with Suwannee river fulvic acid are reported and then extended to “real water samples” from Southern Alberta. The humic model shows different degradation behavior from ‘real’ samples. In addition to reduction of NOM by “self-sensitization”, the active species also achieve reduction of Total coliform and Escherichia coli. The objective of this research is to treat NOM and simultaneously enhance disinfection.

subject: Engineering--Petroleum SAGD

abstract:
The volume of heavy oil and bitumen in the oil sands deposits in Western Canada is similar to that of conventional crude oil in the Middle East. This resource is vast but difficult and energy intensive to extract because of its high oil/bitumen viscosity, over 1,000 to 10,000,000 cp at original reservoir conditions. Current commercial thermal recovery processes used are Steam Assisted Gravity Drainage (SAGD), Cyclic Steam Stimulation (CSS) and steam flood. In this study, the focus is on the SAGD process.

 Currently most completion designs for SAGD are focused on wellbore and very near-wellbore regions and reservoir simulation history matching and forecasts are done using simple sink/source wellbores. In one case the complications of the geological and reservoir heterogeneity are not considered in the design, and in the latter, the impact of completion components on wellbore dynamics is ignored or oversimplified. This study shows that when reservoir and wellbore modeling are coupled, completion designs, history matching and forecasts may change significantly. The difference grows with increased reservoir heterogeneity and complex fluid saturation and properties distribution.

The impact of counter-current heat exchange in concentric configuration was found to be significant in reducing the energy delivered to a reservoir section during circulation. The application of Vacuum Insulated Tubing (VIT) with properly insulated couplings was shown to be promising in reducing the counter-current heat exchange.

Thermal energy distribution during thermal start up and true SAGD stages is key to obtaining high performance bitumen recovery. A synthetic parameter called Oil Production Potential (OPP) was derived to be used as a guide to distribute energy along the SAGD wells. A novel method/workflow was presented that identifies high and low potential reservoir sections to introduce heat to a reservoir accordingly. This workflow was used to design and implement SAGD wellbore completions in Senlac, Saskatchewan.  The field results supported the design workflow and showed significant improvement over conventional completion design methodologies that emphasize on wellbore and very near-wellbore regions only.

subject: General

subject: trade liberalization, consumer prices, difference in difference

abstract: This thesis examines how the Canada - U.S. Free Trade Agreement (FTA) affects prices. I study two potential effects of the FTA: 1) the impact of the FTA on the border cost between Canada and the U.S. and 2) the impact of the FTA on the domestic consumer price of tradable goods in Canada. I make use of disaggregate CPI data for Canada and U.S. to examine the deviations from the law of one price after the FTA and exploit variations in tariff preference across time, characteristics of goods and exposure to trade with the U.S. to analyze the effect of FTA on consumer prices. In my thesis, with respect to the border cost between Canada and the U.S I find that my result shows that border cost still exists following the introduction of the FTA. In terms of the domestic consumer price, my results show that one percentage point increase in the FTA tariff concession decreases the consumer price of tradable goods in the provinces with average exposure to trade with the U.S. by at least 7.19% to at most 11.60%.

abstract: This thesis is an anthropologtcal study of the lndian powwow in the Canadian province of Alberta. It presents the powwow as the result of the dialectics between social hegemony and Indian culture. Its theoretical aim is to develop, from a Historical Materialist perspective, the categories of ldeology and culture through the anthropological praxis. The first chapter consists of a conceptual construction of the powwow, and of a tentaUYe contribution towards the construction of a Marxist category of tradition. The second chapter traces the development of the powwow in the North American Plains, taking a brief look at the ceremonial forms that preceded and shed their influence on this modern ceremonial. Following a lineal time frame, this chapter aims to provide a general historical context to all subsequent exposition. The third chapter presents the history of the powwow in Alberta. Here the powwow is seen as the result of, on the one hand, larger cultural processes affecting North American Plains Indians in general. on the other hand, the powwow is seen as a product of the specific relationship between Indians and non-Indians in this province, from the first days of non-Indian settlements to the present. The fourth chapter traces the general ideological grounds on which the powwow ceremonial is rooted. It emphasizes the importance of hegemony in the creation of a modem Indian identity, and the perception by non-Indians of lndian ceremonialism as a non threatening, functional activity. Chapter five is a composite description of the powwow. It depicts its internal structure and organization, as well as its internal rules. On chapter six the powwow is approached from a dynamic, functionalist perspective. This chapter is an analysis of the powwow within its own phenomenic limits. Finally, chapter seven draws general theoretical conclusions on the interactions among hegemony, the powwow phenomenon and tradition creation.

abstract: Studies have shown that self-compassion, a positive psychological construct characterized by self-kindness, common humanity, and mindfulness, is negatively associated with body dissatisfaction in women. However, little is known about the relationship between self-compassion and body dissatisfaction among men. Body dissatisfaction in men heavily overlaps with a desire for muscularity and leanness for men in contemporary Western society. Given that young adult men are more vulnerable to body dissatisfaction, this study aimed to examine the unique associations between self-compassion and three body dissatisfaction variables in young men: overall appearance evaluation, satisfaction with distinct body areas (e.g., chest, back, and biceps), and drive for muscularity. A sample of 170 men between 18 to 34 years of age from the United States were recruited from Amazon Mechanical Turk (MTurk). Participants completed a demographics questionnaire, one measure of self-compassion, and three measures of body dissatisfaction (appearance evaluation, body areas satisfaction, and drive for muscularity). The findings revealed that self-compassion was uniquely associated with all three body dissatisfaction variables after accounting for body mass index. The findings suggested a potential protective role of self-compassion against body dissatisfaction in young men. Implications for counselling psychology and research highlight the importance of self-compassion as a protective factor within the sociocultural context of male body image.
