description: Socio-economic challenges of large scale oil and gas development, especially oil sands, within municipal boundaries are not given adequate attention in Alberta’s oil and gas development regulatory framework. There is no forum in the framework that allows a thorough consideration and proactive resolution, by responsible governments, of socio-economic challenges of large scale energy development prior to, or at the time of, project approvals. The jurisdiction of municipal authorities to regulate such development is highly circumscribed. None of the recently adopted initiatives by the province seems to have closed this gap in the regulatory framework. The gap exists because Alberta’s oil and gas regulatory framework adopts the unitary model of governance. Given the critical role of public infrastructure and services in energy resource development, the thesis recommends a reform of Alberta’s legislative and regulatory framework for energy development using federalism and its underlying principle of non-centralization. The thesis recommends a suite of non-centralized intergovernmental mechanisms which can conveniently fit into the regulatory framework and anchored in the energy legislative scheme. Using legally-mandated intergovernmental partnerships, Alberta can proactively obviate severe growth pressures, crippling demands on public infrastructure and services, lower quality of life for workers in the host areas, difficulty in attracting and retaining a workforce, and greater risk to energy resource development and huge private investment. A weather-proof regulatory framework with built-in, federal fail-safe mechanisms that enable energy development projects while preserving the wellbeing of host communities is sine qua non to achieve Alberta’s ambitious global energy leadership goals.

description: Canada contains one of the world’s largest bitumen reservoirs, the mining of which produces huge volumes of tailings stored in ponds where they persist as mature fine tailings (MFT) for decades, releasing up to 43,000 m3 d-1 biogenic methane from a single pond. MFT are typically treated with gypsum or polyacrylamide (PAM) to accelerate densification. Microbial reduction of sulfate and methane formation have been associated with improved densification through an unknown mechanism. Here, calcium nitrate treatment balanced with a carbon and energy source (molasses) was found to inhibit methanogenesis and reduced the number of syntrophs and methanogens present. Nitrous oxide emissions were found to be transient while the microbial cell counts increased suggesting biomass has a stronger influence on enhanced microbial densification than biogenic gas. Microbes associated with PAM treated tailings were found to remove amide groups and in the presence of oxygen create a nitrogen cycle while maintaining PAM flocs integrity.

description: Strengthening and repairing of flexural Reinforced Concrete (RC) members with Near-Surface Mounted (NSM) or Externally Bonded (EB) Fibre Reinforced Polymers (FRPs) has shown promising results and gained general acceptance among civil engineers during past decades. Furthermore, the authors of a number of experimental and analytical studies have discussed that using non-prestressed FRPs for strengthening purposes is not completely efficient in terms of exploiting the full capacity of the high-strength FRP materials. Applying prestressing force to the FRP materials not only makes it possible to exploit the full tensile strength of the FRPs but also enhances the serviceability of the flexural member being strengthened by reducing cracks extent/width and by decreasing deflections. A suitable anchorage system that is capable of applying prestressing force to the FRP material in a safe and simple way can increase the efficiency of the strengthening procedure in terms of reducing time and labour costs. The current study was used to investigate the practicality and effectiveness of two newly developed anchorage systems for post-tensioning FRP material. The developed anchorage systems incorporated the use of SMA bars and proved their capability to act as actuators to post-tension the strengthening material. In the first phase of this study, the first anchorage system was used for both the EB CFRP and the NSM CFRP techniques to strengthen RC beams in flexure. In order to evaluate the efficiency of the first anchorage system, seven RC beams were cast and tested under flexural loading, four of which were strengthened using prestressed CFRP material. Tests results from the beams post-tensioned with this first prestressing system proved the capability of the SMA bars to be used as actuators. Based on the test results derived from the first system, the second phase of the experimental investigation aimed at simplifying the prestressing procedure. Therefore, the first prestressing system’s design concept was completely revised and an innovative, practical, and simple anchorage system was developed to prestress NSM CFRP strips for flexural strengthening of RC beams. The modified anchorage system was used to strengthen a large-scale, initially cracked RC beam. The results derived from the second anchorage system showed that the system is capable of applying prestressing force in an efficient way while simplifying the prestressing procedure. To the author’s best knowledge, the study presented in this thesis on using the SMA bars as actuators to prestress FRP materials for flexural strengthening of RC beams is the first of its kind in the world, and the findings suggest a successful transfer of this technology from the research laboratory to application in the field.
Visual representations of homelessness in the canadian public sphere: an analysis of newspaper and photo voice images

Year: 2012

description: The thesis poses a central question: How do images of homelessness, circulated in the Canadian public sphere, simultaneously bolster or disrupt longstanding discourses surrounding homelessness? The question is addressed through quantitative and qualitative analysis of images related to stories on homelessness published in The Calgary Herald, The Toronto Star, and The Vancouver Sun between 2005-2010. Using the same analytic techniques, images taken by homeless individuals in photo voice projects, and published by advocacy groups within the same time period, are also investigated. Two central theoretical tenets ground the research. First, images do not merely reflect an empirical reality, but gain meaning within discursive and conventional contexts. Second, images have the potential to function as inter-subjective and performative instances of communication. These theoretical considerations underwrite the methodological procedure, which triangulates coded content analysis, interpretive qualitative analysis, and socio-historic discursive contextualization. The analysis shows that both the newspaper data and the photo voice data forward a representation of homelessness that emphasizes the personal culpability and experience of homeless individuals, but primarily neglects the structural and systemic causes of the social issue. Several important distinctions are also detected between the two sets of data. The newspaper data emphasizes an "undeserving" image of homeless individuals, one that easily bolsters a punitive and reformative approach to homelessness. Alternatively, the photo voice data emphasizes the personal agency of homeless individuals and opens the possibility for an expanded definition of the public, one that includes those who are not stably housed. The thesis thus offers three main contributions. In terms of visual and communicative theory, the research demonstrates how images function as important nodes for various discursive, representational, and performative meanings. Methodologically, the work uniquely combines quantitative and qualitative methods in an attempt to bridge the gap between larger social meanings and the expression of those meanings in specific mico-instances of cultural articulation. Finally, and substantively, the thesis provides important insight into how contemporary Canadian society conceptualizes homelessness, but does so through a unique and academically overlooked medium, images.

description: В период пандемии новой коронавирусной инфекции (COVID-19) у 80% пациентов болезнь имеет бессимптомный характер или легкое течение. Поэтому основная нагрузка ложится на врачей амбулаторной практики. Своевременно и правильно проведенные диагностические мероприятия позволяют поставить диагноз и оценить тяжесть заболевания в максимально ранние сроки. Даны обзор действующих рекомендаций по проведению диагностических мероприятий в амбулаторных условиях и практические результаты работы амбулаторного КТ-центра. Для подтверждения текущей болезни COVID-19 необходимы оценка эпидемиологического анамнеза и клинической картины, проведение теста амплификации нуклеиновых кислот (ПЦР тест). При клиническом подозрении на COVID-19, отрицательных ПЦР тестах, положительный иммуноферментный анализ на иммуноглобулин IgG позволяет ретроспективно подтвердить диагноз. Рутинное выполнение как первичных, так и контрольных КТ у бессимптомных пациентов и при легком течении COVID-19 не показано.

description: This research was conducted to find out how strategies primary school age children use to solve simple math problems are related to their understanding of mathematical concepts, how this impacts their ability to solve more complex word problems and what we can learn from analyzing the strategies. This research is important because there is a need to improve mathematics education so that children develop deeper, more connected, mathematical understandings. A multiple case study was used; each case was analyzed to see what could be learned. The data was collected in the form of videotaped interviews. These interviews were analyzed and a storyline was composed. The main finding was that the kinds of strategies children use to solve simple math problems do have an impact on how they approach more complex word problems. The implications are that children need to learn efficient strategies early so they can become successful mathematicians.

description: We report the results of Fourier-accelerated HMC simulations of 2D SU(N) X SU(N) principal chiral models for N = 2, 3, 4, 6, 9. These models share several key properties with 4D QCD, such as asymptotic freedom and dynamical mass generation. Even for modest correlation lengths, we find integrated autocorrelation times are decreased by an order of magnitude relative to standard HMC, with relatively little computational overhead. Our results also suggest that the relative advantage of Fourier Acceleration over traditional HMC decreases as N increases, possibly due to the enlarged group space associated with larger N. Our Monte Carlo results agree with the mass spectra and continuum scaling behaviour predicted by the exact solution obtained using the Bethe ansatz.

Privacy as a Social Concept

subject: Information Technology

description: In this thesis I critically examine the traditional account of privacy as a negative right of non-interference and offer instead an alternative framework based on obligations and trust. Privacy is most often described as a value best protected as a right, more accurately as a negative right of non-intrusion. This means that privacy is associated with the private sphere: the individual should be left to decide when he wants to be alone and what he wants to share with others. I begin with an examination of three different distinctions between the public and the private and then I go on to examine two models of privacy: the separation model, where privacy consists of restricted access, and the control model which consists in individual control over certain aspects of one's life. I argue that these models fail to meet many privacy concerns. This becomes most apparent when examining the privacy challenges associated with information technology and biobanks. My alternative account of privacy recognizes how deeply privacy is embedded in social norms and structure. Privacy does not apply to situations where an individual is in isolation, but rather depends on relations to others. This means that privacy is a relational concept: it is an important value in structuring relations between individuals or social institutions. I argue that the framework of rights does not provide an appropriate framework for protecting privacy. Instead, I introduce a framework based on obligations and trust, inspired by Onora O’Neill’s account of perfect and imperfect obligations.
The child and the gothic body : a study of abjection and nineteenth century influences in selected works of contemporary gothic children's literature
Creators: name: Dunford, Laura
Publisher: name: University of British Columbia
Year: 2010

description: This study explores the development of child-monster figures in a selection of contemporary Gothic children’s novels: Surrender by Sonya Hartnett, The Love Curse of the Rumbaughs by Jack Gantos, and The House of the Scorpion by Nancy Farmer. Using a combined psychoanalytic and historicist approach, drawing on the works of Julia Kristeva and numerous nineteenth-century European theorists, including Cesare Lombroso and Max Nordau, this thesis explores how the experience of abjection has continued to be expressed and understood in contemporary texts through nineteenth-century European pseudo-science. The analysis reveals a connection between current cultural anxieties and nineteenth-century anxieties in Britain in regard to rising technology, specifically technology threatening to affect the human body/species. The three primary texts examined in the thesis use the child-monster’s connection with the maternal body to express anxieties about the future of human reproduction.

description: Background: This study explored the sustainability of Screening for Distress, a program that facilitates distress management, in two cancer clinics six months post-implementation. Methods: A mixed-method cross-sectional design was utilized. To assess program sustainability and explore the barriers and facilitators of sustainability 184 charts were reviewed and sixteen semi-structured interviews were conducted. Results: 163 (88.6%) charts had completed tools and a conversation about the tool took place in 130 (79.8%) of those. 89 (54.6%) tools warranted an intervention and 68 (76.4%) of those had an intervention documented. Five themes influencing sustainability emerged: attitudes, knowledge and beliefs, outcome expectancy, implementation approach, integration with existing practices, and external factors. Conclusions: This study suggests that screening was largely sustained, possibly due to positive attitudes and outcome expectancy. However, sustainability may be enhanced by formally integrating screening with existing practices, addressing potential knowledge gaps, and ensuring engagement with all stakeholder groups.

description: Цель. Описание клинической картины, принципов диагностики и лечения первичного пельвиоперитонита у детей на основании опыта работы единственного детского хирургического отделения в КЧР. Материалы и методы. За период 2002–2019 гг. в детском хирургическом отделении Республиканской детской многопрофильной больницы (РДМБ) находилось 70 девочек с острым первичным пельвиоперитонитом. Было проведено ретроспективное исследование медицинских карт, при этом учитывались клинические проявления, данные лабораторных и инструментальных методов исследования. Результаты и обсуждение. Все дети находились в разных возрастных группах, средний возраст исследуемых составил 6 лет 11 мес. Заболевание всегда начиналось с болевого абдоминального синдрома, гипертермия присутствовала у 33 больных, у 24 больных наблюдалась рвота. Воспалительный процесс быстро прогрессировал с появлением перитонеальных симптомов. Анализ лабораторных данных показал нормальные показатели ОАК у 20 больных. Из 70 больных оперативному вмешательству в разные сроки подверглись 63 (90%). Лишь 10 девочек были консультированы гинекологом и, чаще всего гинекологическая патология исключалась. Заключение. Наш опыт лечения больных показывает трудности раннего диагностирования диплококкового перитонита у девочек, отсутствие четких критериев постановки диагноза. Недостаточный охват эхографическим исследованием и отсутствие согласованного взаимодействия между детскими хирургами и гинекологами оставляет множество нерешенных проблем в диагностике и лечении первичного пельвиоперитонита у детей.

description: We define pure radiation metrics with parallel rays to be n-dimensional pseudo-Riemannian metrics that admit a parallel null line bundle K and whose Ricci tensor vanishes on vectors that are orthogonal to K. We give necessary conditions in terms of the Weyl, Cotton and Bach tensors for a pseudo-Riemannian metric to be conformal to a pure radiation metric with parallel rays. Then we derive conditions in terms of tractor calculus that are equivalent to the existence of a pure radiation metric with parallel rays in a conformal class. We also give an analogous result for n-dimensional pseudo-Riemannian pp-waves.

description: Studying embryonic stem cells (ESCs) can further our understanding of biological processes in developmental biology, transplantation, and transgenesis. Mouse and human ESC lines have been established, yet domestic animal ESC studies are lacking. Recently, a goat ESC line has been reported. The aim of this research was to characterize previously cryopreserved goat embryo-derived cell lines and generate additional goat ESC lines for future studies. Results suggest that the cells lines represent mixed populations of inner cell mass and trophoblast derived cells. Moreover, many embryos used for ESC derivation failed to attach, thus media and feeder cell types were tested for their ability to support embryo attachment, an important first step to ESC derivation. The study findings indicate the need for more studies on culture conditions for embryo attachment and efficient inner cell mass isolation for derivation of domestic animal ESCs.

description: The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although the EDGES experiment reported an absorption profile of this signal, there have been concerns about the plausibility of these results, motivating independent validation experiments. One of these initiatives is the Mapper of the IGM Spin Temperature (MIST), which is planned to be deployed at different remote locations around the world. One of its key features is that it seeks to comprehensively compensate for systematic uncertainties through detailed modeling and characterization of its different instrumental subsystems, particularly its antenna. Here we propose a novel optimizing scheme which can be used to design an antenna applied to MIST, improving bandwidth, return loss, and beam chromaticity. This new procedure combines the Particle Swarm Optimization (PSO) algorithm with a commercial electromagnetic simulation software (HFSS). We improved the performance of two antenna models: a rectangular blade antenna, similar to the one used in the EDGES experiment, and a trapezoidal bow-tie antenna. Although the performance of both antennas improved after applying our optimization method, we found that our bow-tie model outperforms the blade antenna by achieving lower reflection losses and beam chromaticity in the entire band of interest. To further validate the optimization process, we also built and characterized 1:20 scale models of both antenna types showing an excellent agreement with our simulations.

description: The heating of the solar corona is one of the big questions in astrophysics. Rapid pulses called nanoflares are among the best candidate mechanisms. The analysis of the time variability of coronal X-ray emission is potentially a very useful tool to detect impulsive events. We analyze the small-scale variability of a solar active region in a high cadence Hinode/XRT observation. The dataset allows us to detect very small deviations of emission fluctuations from the distribution expected for a constant rate. We discuss the deviations in the light of the pulsed-heating scenario.

description: Химическая структура альфа-липоевой кислоты (АЛК) была расшифрована в 1952 г. Ее основная функция – прямое участие в углеводном обмене (аэробный метаболизм пирувата). АЛК играет важную роль в липидном обмене, способствуя сдвигу спектра липидов крови в сторону ненасыщенных жирных кислот, понижению содержания холестерина и насыщенных жирных кислот в крови, тем самым предотвращая развитие атеросклероза. Кроме того, АЛК усиливает усвоение аминокислоты глицин и синтез белков в печени.

description: Foraging decisions that optimize returns should be favoured by natural selection. Nectarivorous animals face problems associated with foraging in three-dimensional space, including difficulty remembering foraging paths and expending energy to work against gravity. Captive individual bumble bees (Bombus impatiens) were video-taped visiting artificial inflorescences to test the effects of three-dimensional (3D) movements and gravity on their behaviour. Bumble bees responded to increased dimensionality by probing fewer flowers for longer durations and responding to self-imposed variation, as a consequence of depleting flowers, by visiting fewer flowers per floral inspection on three-dimensional inflorescences than on two-dimensional inflorescences. When confronted with inflorescences inclined at angles from 0-degrees to 90-degrees, bees demonstrated that flying upward is less time-consuming than flying downward or horizontally, suggesting that their flight capacity is optimized for upward movement. The results provide new insights on the role of cognition and upward movements in bumble-bee foraging.

description: Устранение болевого синдрома, который является проявлением большинства острых и хронических заболеваний человека, относится к числу первоочередных задач лекарственной терапии. Вследствие этого, препараты, обладающие обезболивающим эффектом, в клинической практике и повседневной жизни используются наиболее часто. Лидирующее место среди них занимают нестероидные противовоспалительные средства (НПВС). Мировой фармакологический рынок насыщен лекарственными средствами класса НПВС, существенно отличающимися по своим фармакологическим и потребительским характеристикам. При этом широкий выбор НПВС предоставляет лечащему врачу прекрасную возможность индивидуального подбора препарата, исходя из особенностей пациента и сложившейся клинической ситуации.

description: While most prior research supports psychosocial intervention for Anorexia Nervosa (AN), it has proven to be largely ineffective, with an average of 54% of patients unable to recover fully and 20% remaining chronically ill at a 12-year follow-up (Steinhausen, 2002). Advances in the treatment of AN are desperately needed to improve the prognosis of AN patients, especially since cases have exponentially risen since 2020 (Katella, 2021). Transcranial Direct Current Stimulation (tDCS) is a non-invasive technique that has been proven to be highly effective for treatment-resistant depression (Leggett, 2015). Although some studies have shown similar efficacy in AN remission (physiological and psychological), it is still unclear whether these improvements should be attributed to the remission of depression (Hecht, 2010). This grant proposal aims to determine whether tDCS treatment can prove effective in non-comorbid AN patients, which account for the majority of the disorder demographic (National Eating Disorders Association, 2022). We propose a 6-week tri-weekly tDCS treatment of non-comorbid AN patients at an eating recovery center. AN symptomology will be measured using Eating Attitude Test (EAT-40), the Rosenberg Self-Esteem Scale (RSE), the Body Uneasiness Test (BUT), and the Body Mass Index (BMI). A repeated measures between-subject and within-subject design will compare outcomes measures, including pre-intervention, pot-intervention, and a 1-month follow-up. The outcomes of this study will help determine whether tDCS can be implemented as a treatment option for all AN patients or whether it is only effective in co-morbid populations.

description: Schramm-Loewner evolution appears as the scaling limit of interfaces in lattice models at critical point. Critical behavior of these models can be described by minimal models of conformal field theory. Certain CFT correlation functions are martingales with respect to SLE. We generalize Schramm-Loewner evolution with additional Brownian motion on Lie group $G$ to the case of factor space $G/A$. We then study connection between SLE description of critical behavior with coset models of conformal field theory. In order to be consistent such construction should give minimal models for certain choice of groups.

Using genetics to detect homologous blood doping
Creators: name: Maghsoodi, Mona
Publisher: name: University of British Columbia
Year: 2010

description: Blood doping refers to any illicit means used to increase the erythrocyte count in the body; thereby, increasing oxygen delivery to the muscles. Anti-doping authorities strongly oppose blood doping, and they have prohibited transfusions and the use of substances that increase hemoglobin levels. Athletes now avoid using erythropoeisis-stimulating agents and have reverted to older doping methods, such as blood transfusions. As blood transfusion become more prevalent, current tests for blood transfusions become more problematic. Homologous blood doping is the transfusion of another person’s blood to increase one’s own hemoglobin levels. The current method for detecting homologous blood doping is flow cytometry; however, this method is invasive, costly and requires proper conditions for storage of the blood samples. This study outlines a test that uses genetic differences among individuals in order to detect doping. The proposed anti-doping test eliminates major limitations of other tests. This study also investigates the feasibility and sensitivity of using genetic variations among individuals to detect homologous blood doping. Blood required for doping must be matched for ABO blood type, but because it comes from another individual it will be mismatched for genetic information (i.e. DNA). Given that an individual carries two copies of any chromosome and consequently two copies of most genes, foreign cell detection can be made possible by the discovery of a third or fourth copy of certain genes. Thus, this detection method identifies the presence of genes that do not belong to the athlete. In this study, doping conditions were simulated by mixing bloods at various ratios, including the 90:10 ratio that is commonly observed in athletic doping. PCR based methods of genotyping were used to detect donor DNA in the recipient’s sample. Genetic markers (D1S80, D1S111, D17S30, APO-B and ACE I/D) were used to detect the heterogeneous blood samples. The test successfully identified a 10% allogeneic cell population using a finger prick of blood (50 µL). As that dilution involved a heterozygous donor, this result demonstrates that the assay is sensitive enough to detect a 5% dilution. Overall, this genetic approach allows for the development of an efficient, sensitive and inexpensive test.

description: We present four new seasons of optical monitoring data and six epochs of X-ray photometry for the doubly-imaged lensed quasar Q J0158-4325. The high-amplitude, short-period microlensing variability for which this system is known has historically precluded a time delay measurement by conventional methods. We attempt to circumvent this limitation by application of a Monte Carlo microlensing analysis technique, but we are only able to prove that the delay must have the expected sign (image A leads image B). Despite our failure to robustly measure the time delay, we successfully model the microlensing at optical and X-ray wavelengths to find a half light radius for soft X-ray emission log(r_{1/2,X,soft}/cm) = 14.3^{+0.4}_{-0.5}, an upper limit on the half-light radius for hard X-ray emission log(r_{1/2,X,hard}/cm) <= 14.6 and a refined estimate of the inclination-corrected scale radius of the optical R-band (rest frame 3100 Angstrom) continuum emission region of log(r_s/cm) = 15.6+-0.3.

description: We study a model of learning on social networks in dynamic environments, describing a group of agents who are each trying to estimate an underlying state that varies over time, given access to weak signals and the estimates of their social network neighbors. We study three models of agent behavior. In the "fixed response" model, agents use a fixed linear combination to incorporate information from their peers into their own estimate. This can be thought of as an extension of the DeGroot model to a dynamic setting. In the "best response" model, players calculate minimum variance linear estimators of the underlying state. We show that regardless of the initial configuration, fixed response dynamics converge to a steady state, and that the same holds for best response on the complete graph. We show that best response dynamics can, in the long term, lead to estimators with higher variance than is achievable using well chosen fixed responses. The "penultimate prediction" model is an elaboration of the best response model. While this model only slightly complicates the computations required of the agents, we show that in some cases it greatly increases the efficiency of learning, and on complete graphs is in fact optimal, in a strong sense.
