Adapting the Kodály Method for Private Piano Lesson Instruction: An Applied Study in Effectiveness
Creators: name: Tan, Jing Wen
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Music

description: As a child, I grew up learning piano with an approach where technical exercises and mastery of repertoire through reading was prioritized over aural training and sight reading. In my own teaching as a young professional, I wanted to explore an alternative approach to learning the piano that would be more holistic to the student and incorporate aspects of the Kodály Method which focuses on building a strong musical foundation through singing, vocalizing rhythms, and body movements. This study aims to test the effectiveness of applying the Kodály Method primarily designed for group music classes to conventional private piano lessons, and there is currently very little research to explain how that might be done. I began with a traditional-narrative literature review to examine the Kodály Method and consider what could be incorporated in the private lesson. Classroom observations of Kodály group music classes were studied and based on these findings, I designed and tested a new curriculum for private piano lessons. Through the integration of these two approaches, this study will provide new contributions that will be beneficial to the field of music education. Keywords: The Kodály Method, private piano lesson, classroom observation.

description: The prevalence of child sexual abuse in Indigenous communities is not an isolated phenomenon but rather a symptom of historical and intergenerational traumas resulting from centuries of colonial violence and residential schools. Child sexual abuse can lead to long-term mental health impacts including depression, addiction, and suicide and is correlated with higher incidences of physical and sexual violence throughout the lifespan. Indigenous women in Canada are seven times more likely to be murdered and three times more likely to be a victim of severe violence or sexual assault compared to non-Indigenous women. This inquiry invited 10 Algonquian women Elders and Grandmothers to share survivance stories and teachings to support wholistic lifeways for Indigenous women survivors of child sexual abuse. This dissertation offers insights for: anti-colonizing narratives of child sexual abuse; reframing healing/trauma-based narratives to wholistic lifeways; a working definition of Indigenous sexual health; culturally informed Indigenous sexual health education; coming to know stories as medicine as an Indigenous storytelling methodology; a relational living collective wisdom bundle holding stories and teachings from 10 Algonquian women Elders and Grandmothers; as well as offering guidance for anti-colonizing social work practice and education. Outcomes from this dissertation seek to guide and inform Indigenous and non-Indigenous social service agencies – social workers, health care practitioners, policy makers and funders – serving Indigenous women survivors of child sexual abuse in their programs and services to improve the wellbeing of Indigenous women, their families and communities.
Shear viscosity from thermal fluctuations in relativistic conformal fluid dynamics

description: Within the framework of relativistic fluctuating hydrodynamics we compute the contribution of thermal fluctuations to the effective infrared shear viscosity of a conformal fluid, focusing on quadratic (in fluctuations), second order (in velocity gradients) terms in the conservation equations. Our approach is based on the separation of hydrodynamic fields in soft and ultrasoft sectors, in which the effective shear viscosity arises due to the action of the soft modes on the evolution of the ultrasoft ones. We find that for a strongly coupled fluid with small shear viscosity--to--entropy ratio $η/s$ the contribution of thermal fluctuations to the effective shear viscosity is small but significant. Using realistic estimates for the strongly coupled quark--gluon plasma created in heavy ion collisions, we find that for $η/s$ close to the AdS/CFT lower bound $1/(4π)$ the correction is positive and at most amounts to 10% in the temperature range 200--300 MeV, whereas for larger values $η/s \sim 2/(4π)$ the correction is negligible. For weakly coupled theories the correction is very small even for $η/s=0.08$ and can be neglected.

On Predictive Modeling for Optimizing Transaction Execution in Parallel OLTP Systems

description: A new emerging class of parallel database management systems (DBMS) is designed to take advantage of the partitionable workloads of on-line transaction processing (OLTP) applications. Transactions in these systems are optimized to execute to completion on a single node in a shared-nothing cluster without needing to coordinate with other nodes or use expensive concurrency control measures. But some OLTP applications cannot be partitioned such that all of their transactions execute within a single-partition in this manner. These distributed transactions access data not stored within their local partitions and subsequently require more heavy-weight concurrency control protocols. Further difficulties arise when the transaction's execution properties, such as the number of partitions it may need to access or whether it will abort, are not known beforehand. The DBMS could mitigate these performance issues if it is provided with additional information about transactions. Thus, in this paper we present a Markov model-based approach for automatically selecting which optimizations a DBMS could use, namely (1) more efficient concurrency control schemes, (2) intelligent scheduling, (3) reduced undo logging, and (4) speculative execution. To evaluate our techniques, we implemented our models and integrated them into a parallel, main-memory OLTP DBMS to show that we can improve the performance of applications with diverse workloads.

description: Grand Canonical Monte Carlo is an important method for performing molecular-level simulations and assisting the study and development of nanoporous materials for gas capture application. These simulations are based on the use of force fields and partial charges to model the interaction between the adsorbent molecules and the solid framework. The choice of the force field parameters and partial charges can significantly impact the results obtained, however, there are very few databases available to support a comprehensive impact evaluation. Here, we present a database of simulations of CO2 and N2 adsorption isotherms on 726 metal-organic frameworks taken from the CoRE MOF 2014 database. We performed simulations with two force fields (UFF and DREIDING), four partial charge schemes (no charge, Qeq, EQeq, and DDEC), and three temperatures (273, 298, 323 K). The resulting isotherms compose the Charge-dependent, Reproducible, Accessible, Forcefield-dependent, and Temperature-dependent Exploratory Database (CRAFTED) of adsorption isotherms.

description: Magnesium hydride has great potential as a solid hydrogen (H) storage material because of its high H storage capacity of 7.6 wt%. However, its slow hydrogenation and dehydrogenation kinetics and the high temperature of 300 $^\circ$C required for decomposition are major obstacles to small-scale applications such as automobiles. The local electronic structure of interstitial H in MgH$_2$ is an important fundamental knowledge in solving this problem, which has been studied mainly based on density functional theory (DFT). However, few experimental studies have been performed to assess the results of DFT calculations. We have therefore introduced muon (Mu) as pseudo-H into MgH$_2$ and investigated the corresponding interstitial H states by analyzing their electronic and dynamical properties in detail. As a result, we observed multiple Mu states similar to those observed in wide-gap oxides, and found that their electronic states can be attributed to relaxed-excited states associated with donor/acceptor levels predicted by the recently proposed "ambipolarity model". This provides an indirect support for the DFT calculations on which the model is based via the donor/acceptor levels. An important implication of the muon results for improved hydrogen kinetics is that dehydrogenation, serving as a $reduction$ for hydrides, stabilizes the interstitial H$^-$ state.

The role of somatostatin expression in hair follicle immune privilege
Creators: name: Breitkopf, Trisia
Publisher: name: University of British Columbia
Year: 2012

description: The hair follicle is a mini-organ, consisting of many different types and groups of cells, capable of frequent remodeling and cycles of growth. Immune privilege (IP) is believed to exist in the anagen growth stage of the hair follicle (HF). Previous studies using immunohistology have illustrated unique downregulation of major histocompatibility complex Class I in the HF bulb, as well as expression of immunosuppressive factors in the bulge region. However, quantitative studies and functional studies to clearly demonstrate IP in HF cells are required. My goal was to examine the middle (hair fiber and sheaths) and lower (bulb) portion of the human HF to identify a novel functional mechanism of IP. My hypothesis was that the bulb and the middle third of the hair follicle have functional immune privilege capabilities. In an in vitro experiment, I found that HF cells appeared to suppress histo-incompatible peripheral blood mononuclear cell (PBMC) IFN-gamma secretion relative to epidermal cells. I screened expression of IP-related genes in HFs relative to interfollicular epidermis by quantitative real-time RT-PCR. Briefly, I found significant downregulation of all Class I and Class II HLAs examined in the bulb and sheaths. There were also several genes coding for immunosuppressant secretory factors significantly upregulated in the sheath. Most notably, somatostatin (SST) was significantly upregulated in the sheath 5.9-fold and in the bulb 94.2-fold relative to non-follicular epidermis. This led me to investigate the hypothesis that SST contributes to IP in hair follicles. I found strong expression of SST in the outer root sheath by immunohistochemistry and significant secretion of SST from HF sheath cells compared to epidermal cells in culture. PBMCs cultured with allogeneic immuno-stimulatory epidermal cells and SST secreted significantly less IFN-gamma than controls. Additionally, a SST antagonist drug appeared to interfere with the immunosuppressive effect of sheath cells in culture with allogeneic PBMCs. In summary, these experiments give further evidence in support of HF IP and show that HF bulb or sheath cells may be beneficial in allogeneic transplantation. In principle, SST may have potential as a treatment for scarring alopecia or other inflammatory hair loss disorders.

description: A key aspect of the precision of a mobile robots localization is the quality and aptness of the map it is using. A variety of mapping approaches are available that can be employed to create such maps with varying degrees of effort, hardware requirements and quality of the resulting maps. To create a better understanding of the applicability of these different approaches to specific applications, this paper evaluates and compares three different mapping approaches based on simultaneous localization and mapping, terrestrial laser scanning as well as publicly accessible building contours.

description: We present our near infrared ESO-NTT Ks band observations of the field of IGR J17448-3232 which show no extended emission consistent with the SNR but in which we identify a new counterpart, also visible in Spitzer images up to 24 μm, at the position of the X-ray point source, CXOUJ174437.3-323222. Multi-wavelength spectral modelling shows that the data are consistent with a reddened and absorbed single power law over five orders of magnitude in frequency. This implies non-thermal, possibly synchrotron emission that renders the previous identification of this source as a possible pulsar, and its association to the SNR, unlikely; we instead propose that the emission may be due to a blazar viewed through the plane of the Galaxy.

"as memory permits": Chasing the Spectre of the Indian Agent through Kin and Archive

subject: Education--Language and Literature

description: “as memory permits”: Chasing the Spectre of the Indian Agent through Kin and Archive is a dissertation in two parts: a mixed-form memoiristic work of creative writing prefaced by an exegesis. The exegesis begins with an historical overview of the elusive figure of the Indian Agent, coupling the extensive historical work of John Steckley and Beth Piatote’s theoretical deconstruction of figure to shape an archetype of colonial power within the greater structure of settler colonialism in Canada. I then delve into the scholarship of archival studies, drawing from Antoinette Burton, Saidiya Hartman, Cystal Fraser, and Zoe Todd (among others) to outline limits of and spaces of potential within the colonial archive. In drawing upon the work Margaret Kovach and Willie Ermine, I consider the ethics of engagement for a settler scholar like myself within spaces like the colonial archive. Finally, the exegesis offers a literature review of biotexts and archival writing which serve as frameworks for my own “archive story” (Burton 6), including Daphne Marlatt’s Ana Historic, Fred Wah’s Diamond Grill, and M. NourbeSe Philip’s Zong!. The creative text which follows is a reflection of my process of searching for traces of my grandfather – and in particular, evidence of his role as an Indian Agent – within various modes of archive, ranging from the national archives in Ottawa to the disappearing archive of my grandfather’s memory towards the end of his life. “as memory permits” necessarily interrogates the elusive “voice” of the Indian Agent in its exploration of my grandfather’s role as District Supervisor for the Department of Indian Affairs and Northern Development Canada. While this project is foremost a work of nonfiction, the manuscript also blends elements of fiction, poetry, and found archival text, ultimately shaping a narrative that complicates its genre. Above all, the text is a self-reflexive inquest of my own position as a settler and a descendant of a primary colonial agent in Canada’s long-baked system of settler colonial oppression.
Benefits and Drawbacks of Digital Platforms with Policy Analysis

description: Digital platforms offer numerous advantages to consumers and businesses. Our first stream of research examines the role of shared platforms that are characterized by offering exclusive services to customers, also known as member-only services. Such services mitigate customers' disutility of online purchasing and enable shared platforms to reduce the risk of losing customers to competitors. Using analytical modelling methodologies, our first research chapter aims to understand the economic and social implications of shared platforms. Our finding in this chapter shows that shared platforms maximize their profits by subsidizing the customer-side of the market. Although digital platforms have enlarged contestability in many markets by allowing small firms to develop innovative solutions to compete with monopolies, they have brought new challenges. The second research stream uses analytical modelling methodologies to study two important challenges of digital platforms: biased intermediation and digital piracy. As digital platforms have grown in size and influence, there are concerns about their engagement in anti-competitive behavior, such as having incentives to offer matches that are more profitable to themselves rather than the most relevant ones to users. This conduct is called biased intermediation. Our first research chapter in this stream quantifies the economic and social impacts of biased intermediation and examines whether imposing taxes on digital platforms' revenue can mitigate the potentially harmful effects of biased intermediation. With the rise of digital platforms, it has become easier for individuals to access and share copyrighted material without permission. This has had a significant impact on the revenues of the entertainment industry, with losses estimated to be in the billions of dollars annually. Thus, policymakers must understand the new market realities of digital platforms and reinterpret traditional regulatory approaches accordingly. The second research chapter in the second stream studies how a policymaker can mitigate the harmful effects of digital piracy by imposing fines on pirates, subsidizing legal purchases, and supporting the publisher through restitution within a balanced budget.

description: Free-electron lasers (FELs) can now generate temporally short, high power x-ray pulses of unprecedented brightness, even though their longitudinal coherence is relatively poor. The longitudinal coherence can be potentially improved by employing narrow bandwidth x-ray crystal optics, in which case one must also understand how the crystal affects the field profile in time and space. We frame the dynamical theory of x-ray diffraction as a set of coupled waves in order to derive analytic expressions for the spatiotemporal response of Bragg scattering from temporally short incident pulses. We compute the profiles of both the reflected and forward scattered x-ray pulses, showing that the time delay of the wave $τ$ is linked to its transverse spatial shift $Δx$ through the simple relationship $Δx = cτ\cotθ$, where $θ$ is the grazing angle of incidence to the diffracting planes. Finally, we apply our findings to obtain an analytic description of Bragg forward scattering relevant to monochromatically seed hard x-ray FELs.

description: We study supersymmetric structure of the self-isospectral crystalline chains formed by N copies of the mutually displaced one-gap Lame systems. It is generated by the N(N-1) integrals of motion which are the first order matrix differential operators, by the same number of the nontrivial second order integrals, and by the N third order Lax integrals. We show that the structure admits distinct alternatives for a grading operator, and in dependence on its choice one of the third order matrix integrals plays either the role of the bosonic central charge or the role of the fermionic supercharge to be a square root of the spectral polynomial. Yet another peculiarity is that the set of all the second order integrals of motion generates a nonlinear sub-superalgebra. We also investigate the associated self-isospectral soliton chains, and discuss possible physical applications of the unusual extended supersymmetry.

description: Abstract
Rail transport is generally considered eco-friendly compared to other transport methods. However, it still contributes to environmental impacts, particularly in relation to air
quality. Transport emissions can be classified into two categories: exhaust emissions from engine combustion processes and non-exhaust emissions, including brake wear,
wheel-rail abrasion, as well as particle resuspension. While environmental regulations have been well-established for exhaust emissions, non-exhaust emissions remain
relatively less explored. This research project focuses on measuring and analyzing non-exhaust particle emissions generated during train braking cycles, with a special
interest on ultrafine particles and black carbon, due to their potential health implications. To accomplish these research goals, this project encompasses a literature review
of non-exhaust-related emissions in train systems, a comprehensive data analysis from the brake test bench utilizing various measuring devices and under multiple
measuring programs following the DIN EN 16452:2019. Different operating conditions were evaluated such as the train mass, initial velocity, and contact force between the
wheels and braking pads to determine the most critical operating condition for the emission of particles, ultrafine particles and black carbon

description: The steady-state cooling of a nanomechanical resonator interacting with three coupled quantum dots is studied. General conditions for the cooling to the ground state with single and two-electron dark states are obtained. The results show that in the case of the interaction of the resonator with a single-electron dark state, no cooling of the resonator occurs unless the quantum dots are not identical. The steady-state cooling is possible only if the energy state of the quantum dot coupled to the drain electrode is detuned from the energy states of the dots coupled to the electron source electrode. The detuning has the effect of unequal shifting of the effective dressed states of the system that the cooling and heating processes occur at different frequencies. For the case of two electrons injected to the quantum dot system, the creation of a two-particle dark state is established to be possible with spin-antiparallel electrons. The results predict that with the two-particle dark state, an effective cooling can be achieved even with identical quantum dots subject of an asymmetry only in the charging potential energies coupling the injected electrons. It is found that similar to the case of the single-electron dark state, the asymmetries result in the cooling and heating processes to occur at different frequencies. However, an important difference between the single and two-particle dark state cases is that the cooling process occurs at significantly different frequencies. This indicates that the frequency at which the resonator could be cooled to its ground state can be changed by switching from the one-electron to the two-electron Coulomb blockade process.

description: Ink-jet printed devices on the flexible substrate are inexpensive and large area compatible as compared to rigid substrates. However, during fabrication and service they are subjected to complex strains, resulting in crack formation or delamination within the layers, affecting the device performance. Therefore, it is necessary to understand their failure mechanisms by correlating their electrical or structural properties with applied strain, supported by detailed microstructural investigations.

description: The spectra of several high-redshift (z>6) quasars have shown evidence for a Gunn-Peterson (GP) damping wing, indicating a substantial mean neutral hydrogen fraction (x_HI > 0.03) in the z ~ 6 intergalactic medium (IGM). However, previous analyses assumed that the IGM was uniformly ionized outside of the quasar's HII region. Here we relax this assumption and model patchy reionization scenarios for a range of IGM and quasar parameters. We quantify the impact of these differences on the inferred x_HI, by fitting the spectra of three quasars: SDSS J1148+5251 (z=6.419), J1030+0524 (z=6.308), and J1623+3112 (z=6.247). We find that the best-fit values of x_HI in the patchy models agree well with the uniform case. More importantly, we confirm that the observed spectra favor the presence of a GP damping wing, with peak likelihoods decreasing by factors of > few - 10 when the spectra are modeled without a damping wing. We also find that the Ly alpha absorption spectra, by themselves, cannot distinguish the damping wing in a relatively neutral IGM from a damping wing in a highly ionized IGM, caused either by an isolated neutral patch, or by a damped Ly alpha absorber (DLA). However, neutral patches in a highly ionized universe (x_HI < 0.01), and DLAs with the large required column densities (N_HI > few x 10^{20} cm^{-2}) are both rare. As a result, when we include reasonable prior probabilities for the line of sight (LOS) to intercept either a neutral patch or a DLA at the required distance of ~ 40-60 comoving Mpc away from the quasar, we find strong lower limits on the neutral fraction in the IGM, x_HI > 0.1 (at 95% confidence). This strengthens earlier claims that a substantial global fraction of hydrogen in the z~6 IGM is in neutral form.

description: Over the past two decades there has been a steady trend towards the development of realistic models of cardiac conduction with increasing levels of detail. However, making models more realistic complicates their personalization and use in clinical practice due to limited availability of tissue and cellular scale data. One such limitation is obtaining information about myocardial fiber organization in the clinical setting. In this study, we investigated a chimeric model of the left atrium utilizing clinically derived patient-specific atrial geometry and a realistic, yet foreign for a given patient fiber organization. We discovered that even significant variability of fiber organization had a relatively small effect on the spatio-temporal activation pattern during regular pacing. For a given pacing site, the activation maps were very similar across all fiber organizations tested.

Understanding X-ray reflection emissivity profiles in AGN: Locating the X-ray source

description: The illumination pattern (or emissivity profile) of the accretion disc due to the reflection of X-rays in AGN can be understood in terms of relativistic effects on the rays propagating from a source in a corona surrounding the central black hole, both on their trajectories and on the accretion disc itself. Theoretical emissivity profiles due to isotropic point sources as well as simple extended geometries are computed in general relativistic ray tracing simulations performed on graphics processing units (GPUs). Such simulations assuming only general relativity naturally explain the accretion disc emissivity profiles determined from relativistically broadened emission lines which fall off steeply (with power law indices of between 6 and 8) over the inner regions of the disc, then flattening off to almost a constant before tending to a constant power law of index 3 over the outer disc. Simulations for a variety of source locations, extents and geometries show how the emissivity profiles depend on these properties, and when combined with reverberation time lags allow the location and extent of the primary X-ray source to be constrained. Comparing the emissivity profile determined from the broadened iron K emission line in spectra of 1H 0707-495 obtained in January 2008 to theoretical emissivity profiles and applying constraints from reverberation lags suggest that there exists an extended region of primary X-ray emission located as low as 2rg above the accretion disc, extending outwards to a radius of around 30rg.

description: Group physical activity can provide physical and social benefits; however, social barriers or a lack of social support may affect participation. This study examined social support needs and barriers among older adults who were not participating in group physical activities. Using interpretive description, semi-structured interviews were conducted with 38 older adults (M = 5 70.9 years; 81.6% women). Themes were grouped into two categories. Category one, expectations and initial impressions, consisted of: (1) groups cannot meet everyone's expectations or interests; (2) groups are intimidating to join; and (3) the need for inclusive programming. Category two, social processes within group physical activity, consisted of: (1) modelling physical activity behaviours; (2) sharing information and suggestions about physical activity opportunities; and (3) encouragement and genuine interest. Outreach to this population should aim to address these barriers and utilize these supportive behaviours to reduce feelings of intimidation and promote participation among older adults.

description: We theoretically study how a scattered electron can entangle molecular spin qubits (MSQs). This requires solving the inelastic transport of a single electron through a scattering region described by a tight-binding interacting Hamiltonian. We accomplish this using a Green's function solution. We can model realistic physical implementations of MSQs by parameterizing the tight-binding Hamiltonian with first-principles descriptions of magnetic anisotropy and exchange interactions. We find that for two-MSQ systems with inversion symmetry, the spin degree of freedom of the scattered electron offers probabilistic control of the degree of entanglement between the MSQs.

description: We consider the setting of a Semantic Web database, containing both explicit data encoded in RDF triples, and implicit data, implied by the RDF semantics. Based on a query workload, we address the problem of selecting a set of views to be materialized in the database, minimizing a combination of query processing, view storage, and view maintenance costs. Starting from an existing relational view selection method, we devise new algorithms for recommending view sets, and show that they scale significantly beyond the existing relational ones when adapted to the RDF context. To account for implicit triples in query answers, we propose a novel RDF query reformulation algorithm and an innovative way of incorporating it into view selection in order to avoid a combinatorial explosion in the complexity of the selection process. The interest of our techniques is demonstrated through a set of experiments.
