description: Monitoring and management of large scale applications has always been a complex task, especially because execution workflow and log (outcome from real-time execution) are modeled in a syntactic manner. This information is quite limited and requires manual interpretation, and hence makes the monitoring and management process slow, cumbersome and hard. We propose our solution by semantically (i.e., highly structured, formalized and expressive) modeling of the execution workflow and logs, and then we use Social Network Analysis, Classification, Clustering and Association Rule Mining based approaches to process the semantic information, to help in automating the monitoring and management process. There have been several related efforts, but these solutions still could not achieve the goal effectively as described in this thesis. Two main reasons are: (1) they do not consider the correlation between the expressive modeling of execution workflow and logs, (2) the methods for processing (for monitoring) execution workflow and log methods are quite weak and limited. To overcome the weaknesses of the approaches described in the literature, our proposed solution helps in automating the process of monitoring and management of large-scale distributed applications. We have designed and developed our unique hybrid approach of partially using formal semantics for logs description, as well as social network analysis and data mining tasks to be able to automatically interpret and process the highly structured information from the logs generated during the execution; this way our approach combines the best characteristics of both. Therefore, it helps in improving the automated monitoring and management of applications. Since the logs are generated based on the execution workflow, our solution takes into account the correlation among both. Further the impact and usefulness of our solution have been demonstrated by applying it on real-life application scenario which was defined in consultation with our research collaborators from the industry. Our recent research publications and collaboration with industry have already shown promising results.

description: Stein conjectured that the Hilbert transform in the direction of a vector field is bounded on, say, $L^2$ whenever $v$ is Lipschitz. We establish a wide range of $L^p$ estimates for this operator when $v$ is a measurable, non-vanishing, one-variable vector field in $\bbr ^2$. Aside from an $L^2$ estimate following from a simple trick with Carleson's theorem, these estimates were unknown previously. This paper is closely related to a recent paper of the first author (\cite{B2}).

description: Mining of bitumen from the oil sands located in Alberta, Canada results in the production of oil sands process-affected water (OSPW). Naphthenic acids (NAs) are a constituent of the acid extractable organic (AEO) fraction isolated from OSPW. Detrimental phenotypic responses are apparent in plants exposed to NAs and AEO fraction. The aim of this thesis is to characterize the responses of plant cell structures after treatment with NAs and AEO fraction. Disruption to microtubules, actin filaments, mitochondria, peroxisomes, Golgi bodies, ER, and cell membranes was observed in onion epidermal cells and Arabidopsis thaliana root epidermal cells. Increasing reactive oxygen levels induced by NA and AEO exposure, and decreased cell viability after AEO exposure was also observed. This research represents the initial characterization of organelle and cytoskeletal responses after NA and AEO exposure in eukaryotic cells, and highlights the potential of cytoskeleton and organelle markers as a biosensor for OSPW toxicity.
HOW PERSONAL NARRATIVES IMPROVE WRITING SKILLS OF EFL LEARNERS

Publisher: name: Zenodo
Year: 2025

description: This study investigates how personal narratives enhance the writing skills of EFL learners by promoting self-expression, coherence, and fluency. Writing personal narratives allows learners to organize their thoughts, develop a unique voice, and improve grammatical accuracy. The study employs a mixed-methods approach, combining pre- and post-writing assessments, classroom observations, surveys, and student reflections to measure the impact of narrative writing. The findings suggest that personal storytelling enhances vocabulary use, syntactic complexity, and overall engagement in writing. Moreover, personal narratives create a student-centered learning environment that reduces writing anxiety and fosters creativity. The study highlights the pedagogical value of integrating personal experiences into EFL writing instruction and recommends using structured narrative tasks to improve learners’ confidence, coherence, and linguistic proficiency.

description: Aging is associated with various changes in the vascular system at different structural and functional levels. These changes include increased arterial wall thickness, luminal dilation and reduced compliance. As a major component of the vascular wall, vascular smooth muscle cells (VSMCs) play an important role in exhibiting proper vascular functions. VSMCs behaviors are significantly modified by vascular aging. In this thesis, we study VSMC phenotypic modulation and polyploidiation in vascular aging through three projects. (1) Vascular aging switches VSMC phenotype from a differentiated to a dedifferentiated phenotype, which is characteristic in atherosclerosis. As an important transcription co-activator, myocardin regulates the expression of SM-differentitation marker genes and acts as a critical regulator in VSMC phenotypic modulation in response to various factors. In this thesis, we showed that GSK-3β positively regulates the expression of SM-differentiation markers in VSMCs. We also found that GSK-3β phosphorylats and enhances myocardin transcriptional activity through increasing the recruitment of myocardin to the promoter of its target gene and positively regulates myocardin gene expression. In conclusion, these results suggest that GSK-3β promotes VSMC differentiation through the regulation of myocardin activity. (2) VSMCs polyploidization is a biomarker of vascular aging. VSMC polyploidization and apoptosis co-exist in the aged or hypertensive vascular wall, but whether polyploidization contributes to VSMC apoptosis remains unknown. In this thesis, we found that nocodazole (ND), a microtubule-interfering reagent, induces VSMC polyploidization and apoptosis in a temporal order. Inhibition of ND-induced VSMC polyploidization abolished further apoptosis, suggesting a causal relatioinship between VSMC polyploidization and apoptosis. Also, we identified that mTOR signaling is involved in ND-induced VSMC polyploidization. (3) Accumulative studies have pointed a potential role of mTOR signaling in aging. To further establish the role of mTOR in VSMCs polyploidiation in aging, we established a T-REx system to overexpress mTOR in VSMCs. Overexpression of mTOR activated mTORC1 signaling and further induced VSMC polyploidization and senescence. We also found that autophagy which is negatively regulated by mTORC1 signaling is not involved in mTOR-induced VSMC polyploidy, although autohphagy has been well-established in VSMC senescence. We conclude that mTORC1 signaling induces VSMC polyploidization and senescence through different downstream effecters.
Investigation into the Roles of Ndel1 in the Postnatal Hippocampus

subject: Spatial learning and memory

description: Ndel1 is a microtubule-associated protein (MAP) widely recognized as an integrator of the cytoskeleton. In the developing brain, Ndel1 impacts neurogenesis, nucleokinesis and neuronal migration through interactions with its binding partners, Lis1 and Dynein. Ndel1 knockout mice are embryonic lethal; therefore, the Nguyen lab created conditional knockout mice for Ndel1 (Ndel1 CKO) in CA1 hippocampal excitatory neurons 1 month post birth, to investigate its roles in the postnatal brain. It has been shown that Ndel1 CKO animals exhibit microtubule (MT) fragmentation in CA1 pyramidal neurons associated with synaptic and dendritic pathology, as well as spatial memory impairment. Additionally, Reelin, a secreted glycoprotein involved in the MTs regulation, synaptic plasticity and cell positioning, is reduced in the hippocampus of Ndle1 CKO mice. Interestingly, a single injection of Reelin reduces the MT fragmentation in CA1 pyramidal neurons as well as the synaptic/dendritic pathology. My thesis investigates the significance of Ndel1 and Reelin in postnatal hippocampal integrity and how it impacts spatial learning and memory. My work shows that cellular/anatomical defects do not lead to cell death in the hippocampus of mutant mice. Additionally, CA1 pyramidal neurons become dispersed postnatally, which is decreased with Reelin supplementation. I found an upregulation of Lis1 in Ndel1 CKO hippocampi. As overexpression of Lis1 in the brief presence of nocodazole (MT destabilization agent) generates fragments of MTs disconnected from the centrosomes (Smith et al, Nat Cell Biol 2000), I reasoned that the MTs fragmentation in CA1 pyramidal neurons of Ndel1 CKO mice involves increased Lis1 dosage. Finally, I found that a single injection of Reelin improves the spatial memory of Ndel1 CKO mice during the Morris Water Task. My work provides insight into the postnatal roles of Ndel1 and Reelin in CA1 integrity and how that ultimately impacts spatial learning and memory in Ndel1 CKO mice.

description: Past and recent observations have revealed unexpected variations in the FIR-mm dust emissivity. In the Herschel spectral range, those are often referred to as a 500μm emission excess. Several dust emission models have been developed to interpret astrophysical data in the FIR-mm domain. However, these are commonly unable to fully reconcile theoretical predictions with observations. In contrast, the recently revised two level system (TLS) model seems to provide a promising way of interpreting the existing data. The newly available Herschel Hi-GAL data which covers most of the inner Milky-Way offers a unique opportunity to investigate possible variations in the dust emission properties both with wavelength and environment. By combining the IRIS 100 μm with the Hi-GAL 160, 250, 350 and 500 μm data, we model the dust emission spectra in each pixel of the Hi-GAL maps, using both the TLS model and, for comparison, a single modified black-body fit. The effect of temperature mixing along the line of sight is investigated. We find a slight decrease in the dust temperature with distance from the Galactic center. We also report the detection of a significant 500 μm emissivity excess in the peripheral regions of the plane (35\circ

Grassland debates : conservation and social change in the Cariboo-Chilcotin, British Columbia
Creators: name: Reid, Joanna Isabel Emslie
Publisher: name: University of British Columbia
Year: 2010

description: This thesis explores how a rural landscape – the area from Lillooet to Williams Lake along the Fraser River in British Columbia’s Cariboo-Chilcotin region – becomes the subject of increasing grassland conservation activity and with what consequences. Along the Fraser River lies the northern extent of a once vast, now endangered ecosystem called the Pacific Northwest Bunchgrass Grasslands. The landscape is the traditional, unceded territory of the Secwepemc, St’at’imc and Tsilhqot’in Nations. Ranchers have occupied and used the land since the late 1860s; for many years, the well-known Gang Ranch was the largest in North America. It is a dramatic and ecologically significant landscape to which many people hold strong attachments. Since the 1930s, scientists, government officials, activists, and academics have travelled the region within a broad framework of conservation; these practices have intensified dramatically since the 1990s. My central research questions are: (a) how has scientific conservation extended over this rural landscape and created new social forms; and, (b) how do different people – conservationists, ranchers, and Aboriginal community members – relate to subsequent changes. I argue that ecological ideas, travelling through conservation networks, change the social meaning of the landscape, though in unpredictable ways. I explore the middle Fraser as a site of growing conservation interest and activity. This work is situated within literatures on resource geography and environmental politics in British Columbia, which emphasize complex interrelationships among environmentalists, Aboriginal communities, and rural, non-Aboriginal people who depend on resource use activities for their livelihoods. I am also interested in the productive, disciplinary nature of scientific and state knowledge, as described in the literature on eco-governmentality. However, I see conservation as a set of discourses and practices, dynamic and emergent in a very active material, social world. In this view, I am influenced by Actor-Network Theory, which emphasizes a decentering of agency. Even as conservation changes the meaning of the middle Fraser, it is always through constant, complex negotiation with many different people and diverse non-human elements.

description: Objective: The aim of this thesis was to determine whether there is evidence of an epidemic of major depression in Canadian adolescents. Methods: Prevalence estimates for major depressive episodes (MDE) were derived from a series of Canadian Community Health Surveys. Meta regression and graphical analyses were used to evaluate trends over time. Results: The findings do not support an increase in MDE prevalence in Canadian adolescents from 2000 to 2014 (=0.0006; p=0.532). Age and sex groups did not modify the observance of trends. A post hoc analysis observed mood disorder diagnosis to increase from 2003 to 2014 (=0.0012; p=0.024). Conclusion: MDE prevalence in adolescents has remained relatively stable over the past 15 years. These results suggest mood disorder diagnosis is increasing, which may contribute to the popular belief of an epidemic in adolescents. Policy makers may need to incorporate increasing need of services into future planning.

description: Recent studies have implicated general anesthetic exposure to long-lasting cognitive impairments in children. However, the mechanisms that underlie anesthetic toxicity remain controversial. Here, I used an in vitro primary neuron culture to determine the effects of two volatile general anesthetics – sevoflurane and desflurane – on neuron development. To this end, I first quantified how general anesthetics affect neuron structural development. I show that sevoflurane and desflurane impair neurite growth, neuron polarization, and mitochondrial morphology. Next, I determined the functional impact of general anesthetics on neuronal synaptogenesis and spontaneous synaptic activity. I demonstrate that both sevoflurane and desflurane impair synaptogenesis and spontaneous synaptic current frequency. Finally, I examined a promising mitochondrial protective compound – Mdivi-1 – and found it to reverse many of the noxious effects of sevoflurane and desflurane. These results show, for the first time, several subcellular impacts of sevoflurane and desflurane, which may underlie the learning and memory deficits seen clinically.

description: We consider joint effects of tunneling and spin-orbit coupling on driven by electric field spin dynamics in a double quantum dot with a multi-level resonance scenario. We demonstrate that tunneling plays the crucial role in the formation of the Rabi-like spin-flip transitions. In contrast to the linear behavior for weak electric fields, the spin flip rate becomes much smaller than expected for the two-level model and shows oscillating dependence on the driving field amplitude in stronger fields. In addition, the full spin flip is very difficult to achieve in a multi-level resonant system. These two effects have a similarity with the Zeno effect of slowing down the dynamics of an observable by its measurement. As a result, spin manipulation by electric field becomes much less efficient than expected.

description: By means of sequential and cotunneling spectroscopy, we study the tunnel couplings between metallic leads and individual levels in a carbon nanotube quantum dot. The levels are ordered in shells consisting of two doublets with strong- and weak-tunnel couplings, leading to gate-dependent level renormalization. By comparison to a one- and two-shell model, this is shown to be a consequence of disorder-induced valley mixing in the nanotube. Moreover, a parallel magnetic field is shown to reduce this mixing and thus suppress the effects of tunnel renormalization.

Applications to the quasi-local definition of Black Holes are discussed, with particular emphasis set onto marginally trapped tubes, trapping horizons and the boundary of the region with closed trapped surfaces. Finally, the core of a trapped region is introduced, and its importance discussed.

description: Intelligent coatings, also called smart coatings, refer to coating systems capable of sensing the generation of corrosive environments, and self-responding to corrosion occurrence in demand. In this research, an intelligent coating technology based on doping of home-prepared nanocontainers pre-loaded with inhibitors- in an epoxy host coating was developed for effective corrosion protection of pipeline steel. The performance of benzotriazole (BTA) inhibitors on preventing corrosion of an X65 pipeline steel was investigated in a bicarbonate solution. A layer of protective inhibitor film with a roughness of nano-meter scale was formed on the steel surface, inhibiting corrosion of the steel. To determine the compatibility of nanocontainers with the host coating, multi-layered Halloysite polyelectrolyte nanocontainers were fabricated and doped in an epoxy coating. The coating containing Halloysite nanocontainers possessed enhanced corrosion resistance. The corrosion resistance of the coating was improved with the increasing content of the Halloysite nanocontainers in the coating. To improve the ability of nanocontainers to encapsulate inhibitors BTA, a SiO2 nanoparticle based polyelectrolyte assembly was prepared as the BTA-encapsulating nanocontainers. At either low or high pH value (e.g., pH 2 or 11), the BTA was released to prevent steel from corrosion in chloride solutions. The Korsemeyer-Peppas model provided an estimation of the inhibitor-releasing rate, which served as the base for prediction of the service life of the intelligent coatings. An intelligent coating was developed by doping the BTA-encapsulated, SiO2 nano-particle-based polyelectrolyte nanocontainers in the epoxy coating. For the pipeline steel coated with the intelligent coatings, the corrosion inhibition was time dependent upon self-releasing of the encapsulated inhibitors from the nanocontainers. With the increasing content of the BTA-encapsulated nanocontainers in the coating, both the coating resistance and corrosion resistance of the steel increase, resulting in a reduced corrosion of the steel. Furthermore, superhydrophobic zinc nano-films were fabricated on X65 pipeline steel. The optimal condition for electrodeposition was under the current density of 100 mA/cm2 for 20 mins. The fabricated superhydrophobic, which had a water contact angle up to 158.4° ± 1.5°, possessed a satisfactory antifouling and self-cleaning ability, and provided an effective corrosion protection to the steel in a chloride solution.

description: The present work investigates numerically in two-dimensions the use of multi-internal impinging jets as one of the heat transfer enhancement tools. A numerical model using the lattice Boltzmann method is developed to study the effect of different parameters on the fluid flow structure and the rate of heat transfer from a hot plate kept at a constant high temperature. These parameters include the effect of the variation of the height of the impinging jets from the hot plate, the effect of the variation of the Reynolds number, and the effect of the number of the impinging jets (i.e. the effect of the distance between the jets). The effect of these parameters on the friction coefficient, pressure drop, and the Nusselt number is presented and discussed. Finally, the findings are concluded and some recommendations and suggestions are given to extend this work.

description: Among the lattice loop models defined by Pearce, Rasmussen and Zuber (2006), the model corresponding to critical dense polymers ($β= 0$) is the only one for which an inversion relation for the transfer matrix $D_N(u)$ was found by Pearce and Rasmussen (2007). From this result, they identified the set of possible eigenvalues for $D_N(u)$ and gave a conjecture for the degeneracies of its relevant eigenvalues in the link representation, in the sector with $d$ defects. In this paper, we set out to prove this conjecture, using the homomorphism of the $TL_N (β)$ algebra between the loop model link representation and that of the XXZ model for $β= -(q+q^{-1})$.

description: In this research lab and field corrosion coupon testing was completed to determine corrosion rates on relevant Steam Assisted Gravity Drainage (SAGD) metals. Evaluating how rates varied with well depth, environment, and a dominating corrosion mechanism. Materials tested in the lab were 1018 carbon steel, Deloro-40 and Stellite-6, TN-55TH, galvanized (GLV) J-55 and K-55. Field coupon materials included L-80, J-55, and a GLV-J55+J-55 couple. Corrosion rates decreased from 0.0178mm/y at the wells bottom to 0.0145mm/y at higher elevations. This corresponded to a decrease in iron sulfide (FeS) scale content from the well bottom upwards formed through a solid-state reaction between aqueous H2S and the metal. High average corrosion rates of 0.263mm/y were measured in the lab, compared to the low 0.0183mm/y in field studies. This difference is due to the inhibiting effects of oil in the field which inhibits corrosion rates and the longer test duration.

description: Research in Human Resource Management (HRM) has helped scholars understand the value of systems of people practices for organizations, but the discipline faces a number of challenges in moving its agenda forward. In particular, understanding and specifying how those systems translate into improved organizational performance has proved elusive. The studies in this thesis examine some of these challenges in dimensions of time, theory linkage and process. The first study, an event history analysis of longitudinal practice data of Canadian companies, finds that HRM practices associated with the strategic agenda are abandoned at a surprising rate over time. The second study, a bibliometric network analysis of HRM and strategy literature, finds that the theoretical links to strategy are not developing in the direction that HRM scholars predicted. The third study, a case study of apprenticeship practices in the industrial construction industry, finds consensus between supervisors and senior management on the ends, but not the means by which those practices are implemented. Each study provides findings that diverge from the expectations found in HRM literature. Taken together, they offer a novel perspective and fruitful paths forward on the challenges facing the field.
Individual Eigenvalue Distributions for the Wilson Dirac Operator

description: We derive the distributions of individual eigenvalues for the Hermitian Wilson Dirac Operator D5 as well as for real eigenvalues of the Wilson Dirac Operator DW. The framework we provide is valid in the epsilon regime of chiral perturbation theory for any number of flavours Nf and for non-zero low energy constants W6, W7, W8. It is given as a perturbative expansion in terms of the k-point spectral density correlation functions and integrals thereof, which in some cases reduces to a Fredholm Pfaffian. For the real eigenvalues of DW at fixed chirality nu this expansion truncates after at most nu terms for small lattice spacing "a". Explicit examples for the distribution of the first and second eigenvalue are given in the microscopic domain as a truncated expansion of the Fredholm Pfaffian for quenched D5, where all k-point densities are explicitly known from random matrix theory. For the real eigenvalues of quenched DW at small "a" we illustrate our method by the finite expansion of the corresponding Fredholm determinant of size nu.

What it Means to be Rational: An Analysis on Knowledge, Rational Deliberation, and Action
Creators: name: Elkin, Lee

Year: 2013
Subjects: subject: Philosophy

subject: Epistemology

description: The following thesis is an analysis on the relation between knowledge and reasoning about how to act. It seems fairly intuitive that one is rational to act on what one knows. But unfortunately, the issue is not so simple. In constructing a normative framework for practical reason, one could either require knowledge to be a necessary requirement for practical reason or one might only hold that knowledge is sufficient for reasoning about what to do, though having knowledge is not a necessary requirement. In this thesis, I will defend the latter.
The modes of limited transpositions in Olivier Messiaen's music : transformational and tonal approaches
Creators: name: Simpson-Litke, Rebecca
Publisher: name: University of British Columbia
Year: 2010

description: This thesis provides a detailed examination of the theoretical structures, compositional possibilities, and musical effects of the Modes of Limited Transpositions, as discovered by Olivier Messiaen and explored throughout his career, but primarily in his early works. In the introductory chapter, I discuss Messiaen’s unique perspective on these collections, including an investigation into the composer’s synaesthetic sound-colour perception and artistic preferences. Taking Messiaen’s own writings as my point of departure, I develop a more systematic method for generating and labeling these transpositionally symmetrical collections, situating each of them within a larger family of augmented-triad-based and/or tritone-based modes. In the main body of the thesis, I explore Messiaen’s use of these modes from three interrelated perspectives—modal, chromatic, and tonal—each requiring distinct analytical tools. In Chapter 1, entitled “A Modal Perspective,” I adapt concepts from transformational theory to create a modal transformational approach. In the analyses of this chapter, musical objects and transformations are considered not in reference to a mod-12 chromatic universe, but within purely modal contexts. (In the accompanying appendix to this chapter, I develop the concept of an abstract Tonnetz, highlighting some ways in which new objects, transformations, and spaces may accommodate a wider variety of analytical contexts.) In Chapter 2, entitled “A Chromatic Perspective,” I describe transformational relationships between modes of different types, and the standard twelve-tone universe is used as the backdrop against which objects and transformations are heard. I create geometric models of the augmented-triad-based and tritone-based families and demonstrate their analytical usefulness. In Chapter 3, entitled “A Tonal Perspective,” I examine ways in which Messiaen exploits the tonal resources of his modes in order to imitate traditional harmonic and melodic structures. I discuss the various ways in which focal centres are created, and how superimposed layers or juxtaposed blocks of music may be unified (or kept aurally distinct) via references to tonality. In the final Chapter 4, then, I show how all three perspectives work together in my analysis of a complete song, in which Messiaen beautifully depicts the sentiments of the text through the creation of a rich fabric of musical relationships.

description: Calculations are performed of the phase shift caused by the spatial modulation in the plasma density due to interference between a strong pump pulse and a weak probe pulse. It is suggested that a recent experiment [Loriot et al., Opt. Express v. 17, 13429 (2009)] observed an effective birefringence from this plasma grating rather than from the higher-order Kerr effect.

Rare Plant Distribution Modelling: Exploring Predictor Datasets - A Case Study in Southeast Alberta

subject: FOS: Biological sciences
subject: species distribution modelling

subject: environmental predictors
subject: Bias
subject: conservation applications

description: Modelling rare plant distribution has challenges, but that does not preclude its use supporting conservation management. Challenges relate to uncertainties in source datasets, rare species ecology, modelling techniques, and how they interact to influence model predictions. Further challenges are introduced when biased model predictions are applied to rare plant conservation efforts. Through a case study modelling the distribution of Moquin’s sea-blite (Suaeda moquinii), a rare grassland plant, study design considerations were framed with emphasis on deriving ecologically relevant habitat predictors and addressing bias introduced during model development. Models performed well and provided insight into Moquin’s sea-blite habitat specificity in southeast Alberta. Biases were reduced in model design through data handling methods, validating predictions with field observations, and comparing different predictor data treatments. Uncertainties associated with a variety of biases persisted and the effects of these on model performance were discussed in the context of two conservation management scenarios.
