description: This thesis builds on the current literature on immigrant well-being by providing a nationally representative examination of how occupation, measured in terms of occupational socio-economic score (OSS), affects immigrant mental health and life satisfaction. Using the Canadian Community Health Survey (CCHS) 2003-2014 linked to the Longitudinal Immigration Database (IMDB) 1980-2018, I used modern mediation techniques to examine how personal income and community belonging act as personal resources that potentially mediate the effect of occupation on the mental health and life satisfaction of economic immigrants (n=8,997), sponsored immigrants (n=4,920), refugees (n=2,033) and non-immigrants (n=190,992). The Stress Process Model (SPM) frames the investigation. I find that OSS does indirectly affect well-being, but the mechanisms through which it operates differ for various immigrant groups, and across the two measures of well-being. Personal income positively links OSS and self-rated mental health for non-immigrants and economic immigrants, but not for sponsored immigrants or refugees. In terms of life satisfaction, income was a significant mediator for economic immigrants, sponsored immigrants, and non-immigrants. On the other hand, community belonging negatively links OSS to both self-rated mental health and life satisfaction for both sponsored immigrants and non-immigrants, but not for economic immigrants or refugees. These findings suggest the heterogeneity of ways through which resources impact the mental well-being of different immigrant groups. Several suggestions for future research and policy implications are also discussed.

description: We compute the six-dimensional effective action of the heterotic string compactified on K3 for the standard embedding and for a class of backgrounds with line bundles and appropriate Yang-Mills fluxes. We compute the couplings of the charged scalars and the bundle moduli as functions of the geometrical K3 moduli from a Kaluza-Klein analysis. We derive the D-term potential and show that in the flux backgrounds U(1) vector multiplets become massive by a Stuckelberg mechanism.

Evaluation of linear segment length and local curvature radius along airfoil leading and trailing edges
Creators: name: Razive, Mohammad Nahid Islam
Publisher: name: University of British Columbia
Year: 2012

description: Airfoil is the basic profile geometry of impeller and turbine blades. The operational efficiency of these blades is governed by stringent tolerance specifications on the airfoils. The specified tolerances are commonly evaluated from discrete coordinate data collected in sections by a touch-probe coordinate measuring machine (CMM). These measurement data are subject to inspection inaccuracies associated with CMM measurement operation. Apart from well-known inspection parameters like profile tolerance, profile thickness and edge radius, the leading edge (LE) and trailing edge (TE) are specified with a unique set of geometric parameters like the maximum linear segment length restriction and the minimum curvature radius restriction. This thesis focuses on evaluating these two localized geometric restrictions along the leading edge and trailing edge of an airfoil. This thesis first presents a robust algorithm to identify the longest linear segment. The main feature of the proposed algorithm is the explicit consideration of measurement uncertainty. The algorithm starts by detecting relatively small linear segments and then merges these segments to determine the longest feasible linear segment under given measurement uncertainty. The effect of measurement uncertainty and data point resolution on the performance of the presented algorithm is demonstrated through case studies. Once the linear segments are identified and excluded, the remaining data points only belong to the non-linear segments. As minimum radius can occur at any location, curvature radius at each point along the non-linear segments is evaluated. Curvature radius at a specific point can only be estimated from its neighborhood. The chosen neighborhood size needs to be balanced between capturing local curvature attribute and effectively considering the effect of measurement uncertainty. An algorithm is thus proposed to evaluate radius via a rolling scheme of five consecutive data points in order to retrieve the local curvature information of the mid-point. A statistical approach is employed where all feasible radii are considered in order to reliably estimate the desired radius. Biarc construction is used as a tool to calculate radius. Compared with existing radius estimation methods, the proposed method has demonstrated to yield better accuracy with varying measurement uncertainty and data point resolution.

description: Electrolysis of hydrogen sulfide (H2S) offers a green and zero-emission process for producing hydrogen and for treating the harmful H2S from oil and gas industries. However, the development of such technology requires an efficient and stable catalyst. Herein, we investigate the mechanism of electrochemical H2S oxidation reaction (H2SOR) over various metal oxides and metal sulfides using Density Functional Theory (DFT) calculations. We demonstrate why RuO2 has been widely reported as an active H2SOR catalyst. We also show that metal oxides are susceptible to sulfur poisoning, which makes their long-term commercial operation challenging. By including surface coverage analysis for S-intermediates, we identify TiO2 as a promising and durable catalyst for H2SOR with 0.49 V calculated overpotential. We also investigated the H2SOR activity of pristine and doped metal sulfides. We show that even doping metal sulfides reduces the overpotential needed to drive the H2SOR and facilitates hydrogen production. This research paves the way for the creation of more effective catalysts by providing a computational understanding of H2S electrolysis over various catalysts.

Genomic Signatures of Within-Generation Selection in Coho Salmon (Oncorhynchus kisutch) under Enriched Hatchery-Rearing Practices and in the Wild
Creators: name: Bull, James Kenneth

Subjects: subject: Genetics

description: Salmonids occupy central roles in the ecological and human communities in which they occur. As such, many salmonid populations are heavily managed for conservation and to support their harvest. This often involves hatcheries, which typically use captured mature adults to produce fertilized eggs which are reared to the smolt life-history stage, with resultant smolts released into the wild. Despite a history of over 150 years of hatchery use, fundamental questions remain about the ecological and evolutionary impacts of hatcheries on released fish and on the wild populations released fish interact with. Chief among these questions is the role and impact of selection in hatchery fish compared to wild fish and if domesticating processes are inevitable. In this thesis, I present a detailed investigation of the population genomics of an integrated hatchery-wild coho salmon (Oncorhynchus kisutch) population subjected to long-term experimental rearing under conventional hatchery environments, and under enriched hatchery environments designed to mimic aspects of the wild environment in efforts to mitigate potential effects of hatchery rearing. Specifically, I investigated (1) if spatial genetic structuring occurs among wild fish in this system, (2) if selection is detectable for survival-at-sea and for survival across the lifecycle within a single generation, and (3) if such selection depends on the rearing environment fish experience in the hatchery. I additionally reviewed what is known about gene expression under domestication in salmonids. I found no evidence for spatial genetic structuring among wild fish, indicating the typical strategy of restricted sampling of wild fish for inclusion in the hatchery broodstock should not drive differentiation between hatchery and wild fish. I also found evidence for within-generation selection for both survival-at-sea and survival across the lifecycle, and most importantly, that these signatures of selection differed between hatchery fish reared under different environments. Notably, signatures of selection for fish reared under enriched environments were not more similar to those observed in wild fish, compared to conventionally reared fish, indicating work remains in designing hatchery environments that mimic those aspects of the wild environment required to produce wild-like fish, and with implications for captive rearing programs more broadly.

description: We systematically analyze the various phase transitions of the anisotropic Dicke model that is endowed with both rotating and counter-rotating light-matter couplings. In addition to the ground state quantum phase transition (QPT) from the normal to the super-radiant phase, the anisotropic Dicke model also exhibits other transitions namely the excited state quantum phase transition (ES- QPT), ergodic to non-ergodic transition (ENET) and the temperature dependent phase transition. We show that these phase transitions are profitably studied not only with the standard consecutive level spacing ratio, but also with the aid of various eigenvector quantities such as von Neumann entanglement entropy, the participation ratio, multifractal dimension and mutual information. For ENET, both the statics and dynamics of the participation ratio offer a consistent and useful picture. An exciting finding from our work is that the ESQPT and the ENET are closely related to each other. We show this with the aid of two characteristic energies in the spectrum corresponding to jumps in von Neumann entropy.

description: Optomechanical cooling of levitated dielectric particles represents a promising new approach in the quest to cool small mechanical resonators towards their quantum ground state. We investigate two-mode cooling of levitated nanospheres in a self-trapping regime. We identify a rich structure of split sidebands (by a mechanism unrelated to usual strong-coupling effects) and strong cooling even when one mode is blue detuned. We show the best regimes occur when both optical fields cooperatively cool and trap the nanosphere, where cooling rates are over an order of magnitude faster compared to corresponding single-sideband cooling rates.

description: Osteoarthritis (OA) is a debilitating musculoskeletal disease affecting approximately one-third of the adult Canadian population. The most common location of OA occurring is at the knee. OA can affect all three compartments of the knee joint. Knee braces are commonly prescribed for knee OA to reduce pain and improve user function. The LevitationTM “Tri-Compartment Unloader” knee brace (Spring Loaded Technology) was designed to reduce forces in all three compartments of the knee by lowering quadriceps muscle activity, a predictor of knee joint contact force. The effect of the Levitation brace on tri-compartment joint contact forces has yet to be fully investigated. The research objective of this study was to preliminarily investigate the effect of the Levitation brace in a healthy subject on 3-dimensional (3-D) joint kinematics and kinetics, and muscle activity, using biomechanical and musculoskeletal (MSK) computer modeling assessments during a step-back lunge movement. An experimental pilot study was performed to assess the effect of the Levitation brace on joint kinematics and kinetics using a novel combined motion analysis and High Speed Biplanar Radiography approach. A musculoskeletal modelling approach was developed to analyze the effect of the Levitation brace on tri-compartment contact forces, resultant joint moments, and simulated muscle activations. The experimental study results indicate that the Levitation brace did not impact knee joint angles between bracing conditions. The brace reduced knee abduction/adduction and internal/external rotation moments when compared to the unbraced condition. The brace’s impact on flexion/extension moments was unclear. The MSK modelling results predict that the Levitation brace reduced peak contact forces in each of the knee compartments when compared to the unbraced condition. The brace increased quadriceps muscle activation and peak knee extension moments compared to the unbraced condition, contrary to what was expected. Together, the experimental and musculoskeletal modelling results provide a 3-D evaluation of the effect of the Levitation brace on tri-compartment knee joint dynamics which can be used to provide further understanding of the brace design efficacy for OA treatment, and can be applied to improve brace product design and provide insights for future product developments.

description: We investigate the variability properties of main sequence stars in the first month of Kepler data, using a new astrophysically robust systematics correction, and find that 60% of stars are more variable then the active Sun. We define low and high variability samples, with a cut corresponding to twice the variability level of the active Sun, and compare the properties of the stars belonging to each sample. We show tentative evidence that the more active stars have lower proper motions and may be located closer to the galactic plane. We also investigate the frequency content of the variability, finding clear evidence for periodic or quasi-periodic behaviour in 16% of stars, and showing that there exist significant differences in the nature of variability between spectral types. Of the periodic objects, most A and F stars have short periods (< 2 days) and highly sinusoidal variability, suggestive of pulsations, whilst G, K and M stars tend to have longer periods (> 5 days, with a trend towards longer periods at later spectral types) and show a mixture of periodic and stochastic variability, indicative of activity. Finally, we use auto-regressive models to characterise the stochastic component of the variability, and show that its typical amplitude and time-scale both increase towards later spectral types, which we interpret as a corresponding increase in the characteristic size and life-time of active regions.

The Mariposa Folk Festival as a Reflection of Canadian Culture

Subjects: subject: History--Canadian
subject: History--Modern

description: The Mariposa Folk Festival was established in Orillia, Ontario in 1961. It was one of the first festivals of its kind in Canada. Although organizers took inspiration from similar events in the United States—such as the Newport Folk Festival—the festival remained a distinctly Canadian cultural institution throughout the 1960s. This thesis argues that the development of the Mariposa Folk Festival throughout its inaugural decade reflected changes in Canadian national identity in this period, most notably in relation to reconsideration of English-Canadian culture as a core component of national identity. By responding to broader shifts in Canadian culture, Mariposa's organizers were able to curate a festival that was consistent with audiences' values and interests while also introducing attendees to music that they may not have previously had exposure to. This thesis explores the festival’s development in three phases, first looking into the period from 1961 to 1964, when the event's organizers primarily focussed on English-Canadian folk music. The festival’s next phase—1965 to 1968—demonstrated influence from the Canadian centennial celebrations taking place around the country at this time. Finally, the years 1969 to 1971 saw a shift towards multiculturalism at Mariposa, demonstrated through an increased focus on Indigenous art and culture and non-Western music.
Molecular dynamics study of effects of geometric defects on the mechanical properties of graphene
Creators: name: Mallika Arachchige, Nuwan Dewapriya
Publisher: name: University of British Columbia
Year: 2012

description: Graphene is a flat monolayer of carbon atoms arranged in a two-dimensional hexagonal lattice. It is the strongest material ever measured with strength exceeding more than hundred times of steel. However, the strength of graphene is critically influenced by temperature, vacancy defects (missing carbon atoms) and free edges. A systematic Molecular Dynamics (MD) simulation study is performed in this thesis to understand the effects of temperature, free edges, and vacancy defects on the mechanical properties of graphene. Results indicate that graphene has a positive coefficient of thermal expansion. However, the amplitude of intrinsic ripples (out-of-plane movement of carbon atoms) increases with increasing temperature, which reduces the net effect of thermal expansion. This is probably the reason for negative values of thermal expansion coefficient observed in some experiments. The MD simulations provide significant insights. At higher temperatures the sheets are observed to fail at lower strains due to high kinetic energy of atoms. Excess edge energy of a narrow graphene sheet is found to induce an initial strain at equilibrium configuration. Free edges have a greater influence on the mechanical properties of zigzag sheets compared to those of armchair sheets. Simulation of sheets with vacancy defects indicates that a single missing atom could reduce the strength by nearly 20%. It is also found that the calculated strength based on Griffith's theory falls below the results from MD simulations. The results obtained in this study are useful to the design and fabrication of graphene based nano-devices.

description: Comprehensive analysis on the light Higgs scenario of the minimal supersymmetric standard model is performed in the framework of the non-universal Higgs mass model (NUHM). The NUHM is known to be the simplest framework realizing the light Higgs scenario with the unifications of gaugino and sfermion masses at the scale of grand unified theory being consistent. All important constraints from collider experiments, flavor-changing processes, and cosmological observations are considered in order to clarify the allowed region of the model parameter space, where the Markov Chain Monte Carlo method is used to obtain the region. We show that the region is excluded by current LHC results for the SUSY particle searches. We discuss possible extensions to save the LHS. Even with such extensions, the measurement of B_s to mu^+ mu^- would enable us to test the LHS in the near future.

description: Thanatechnology is a budding field that explores the nexus of technology within grieving rituals and experiences. Previous research indicates that social media has become part of our everyday communication, and has expanded to our grieving rituals. However, the pandemic acted as a catalyst to adapt the tools we had to cope with loss. This thesis comprised two studies to understand grief communication in digital spaces. In the first study, we conducted a scoping review to grasp what has already been reported on grieving on social media. We extracted 47 peer-reviewed articles based on our inclusion criteria. We were able to identify different domains of information including platform characteristics, the types of users, the transformation of the griever’s relationship to the deceased, community interactions, and functionalities of social media connection. Grieving online can provide a connection to other grievers and maintain a connection with loved ones. The scoping review created a foundation of knowledge in digital grieving prior to the pandemic. We then conducted a second study, a reflexive thematic analysis using naturally occurring data to understand the griever’s experiences during the pandemic. Five discussion threads were extracted from a grieving community on Reddit who lost someone because of the COVID-19 virus. We identified that users discussed the COVID-19 virus as an anthropomorphized “Evil Monster” that took away their loved ones. Other themes identified included unfairness from pandemic loss and restrictions, encountering losses despite extensive safety precautions, understanding of unique pain from COVID-19 loss, sharing the grieving experience online, and finding compassion with other members. This research provides a historic snapshot of the grief experience during the pandemic as our communication shifted. The results of this study are timely in relation to the introduction of artificial intelligence and allude to future directions for thanatechnology studies. Lastly, the ethical responsibility of using social media for data collection is addressed.
Children’s Sensitivity to Emotional Prosody in an Unfamiliar Language: The Role of Referential Context
Creators: name: Waly, Yomna Khaled
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Psychology--Developmental
subject: Psychology--Cognitive

description: Research suggests that preschoolers use emotional prosody to make sophisticated judgements, such as using a speaker’s tone of voice (happy vs. sad) to identify an intended referent (e.g., a broken vs. intact toy). However, 4-year-olds only make these associations in familiar, but not unfamiliar languages. Here, we sought to understand these discrepant findings by investigating the role of referential cues (i.e., cues that signal the speaker’s intended object) in children’s use of emotional prosody to resolve referential ambiguity. Results indicated that 4-year-old children did not use emotional prosody to modulate their looking nor pointing to the target object. Instead, they consistently fixated to the negative object whilst pointing to the positive object. Conversely, 8-year-olds looked at and point to the target object during sad-sounding trials. Their looking and pointing to the negative object was attenuated during happy-sounding trials such that they looked and pointed equally to both objects. Taken together, findings suggest that even in the presence of heightened referential cues, use of emotional prosody in an unfamiliar language remains an emergent skill during childhood.

description: 3D shape completion from point clouds is a challenging task, especially from scans of real-world objects. Considering the paucity of 3D shape ground truths for real scans, existing works mainly focus on benchmarking this task on synthetic data, e.g. 3D computer-aided design models. However, the domain gap between synthetic and real data limits the generalizability of these methods. Thus, we propose a new task, SCoDA, for the domain adaptation of real scan shape completion from synthetic data. A new dataset, ScanSalon, is contributed with a bunch of elaborate 3D models created by skillful artists according to scans. To address this new task, we propose a novel cross-domain feature fusion method for knowledge transfer and a novel volume-consistent self-training framework for robust learning from real data. Extensive experiments prove our method is effective to bring an improvement of 6%~7% mIoU.
Salience-based stakeholder selection to maintain stakeholder coverage in solving the next release problem

description: Stakeholders quantification plays a basic role in selecting the appropriate requirements because their judgement is a major criteria since not all of them have the same importance. Original proposals quantified stakeholders assigning them a weight. Nonetheless, actual projects manage a numerous stakeholders community hindering the inclusion of all their weights. This work proposes grouping strategies as means to reduce the number of stakeholders to manage in requirements selection keeping a proper coverage (i.e. howthe selection fulfils stakeholder demands). Our approach is based on stakeholders' salience, defined in terms of power, legitimacy and urgency attributes. Diverse strategies are applied selecting important stakeholders groups in a specific project. We use k-means}, k-medoids and hierarchical clustering, after deciding the number of cluster (4 and 3) based on validation indices. Either for all the stakeholders and each important group several requirements selection optimization problems have been solved. Tests find no significant differences for coverage when important stakeholders are filtered using clustering, regardless of the technique and number of groups, with a reduction between 66.32% to 87.75% in the number of stakeholders being considered. Applying clustering methods on data obtained from a real-world project is useful to identify the group of important stakeholders. The number of groups suggested matches the stakeholders theory and the coverage values in the requirements selection is kept.

description: Context. The Cepheid mass discrepancy, the difference between masses predicted from stellar evolution and stellar pulsation calculations, is a challenge for the understanding of stellar astrophysics. Recent models of the eclipsing binary Cepheid OGLE-LMC-CEP-0227 have suggested that the discrepancy may be resolved. Aims. We explore for what physical parameters do stellar evolution models agree with the measured properties of OGLE-LMC-CEP0227 and compare to canonical stellar evolution models assuming no convective core overshooting. Methods. We construct state-of-the-art stellar evolution models for varying mass, metallicity, and convective core overshooting and compare the stellar evolution predictions with the observed properties. Results. The observed mass, effective temperature, and radius of the two stars in the binary system are well fit by numerous combinations of physical parameters, suggesting a Cepheid mass discrepancy of 10-20% relative to canonical stellar evolution models. Conclusions. The properties of the observed binary Cepheid suggest that the Cepheid mass discrepancy is still a challenge and requires more specific observations, such as the rate of period change, to better constrain and understand the necessary physics for stellar evolution models to resolve the discrepancy.

description: Following the thermodynamic formulation of multifractal measure that was shown to be capable of detecting large fluctuations at an early stage, here we propose a new index which permits us to distinguish events like financial crisis in real time . We calculate the partition function from where we obtain thermodynamic quantities analogous to free energy and specific heat. The index is defined as the normalized energy variation and it can be used to study the behavior of stochastic time series, such as financial market daily data. Famous financial market crashes - Black Thursday (1929), Black Monday (1987) and Subprime crisis (2008) - are identified with clear and robust results. The method is also applied to the market fluctuations of 2011. From these results it appears as if the apparent crisis of 2011 is of a different nature from the other three. We also show that the analysis has forecasting capabilities.

description: Altar to the Unknown God is an MFA thesis exhibition concerned with twenty-first century spiritual and religious expressions of visual identity, as well as and the academic structures employed when formulating interpretations of their meaning and validity. Informed by a literary analysis on secularism and contemporary art criticism, this studio-led research utilizes a rhizomatic philosophical structure that seeks expansion and connective multiplicities rather than a definitive conclusion. Towards this goal, the literary investigation endeavors to define and demystify the complex interrelations between secularism as a pluralistic cultural condition with the academic challenge behind the formation of a method of theological art criticism. The studio-produced visual artwork is both informed by this analysis and rhizomatically seeks its expansion through an introspective investigative process. This inquiry aims to theorize an academic interpretative language capable of taking visual displays of enchantment as genuine, rather than naive depictions of superstition, thus producing structures and inter-religious dialogue that is inclusive of spiritual identity in the shifting landscape of the twenty-first century.

description: Die vorliegende Arbeit untersucht die Verbreitung (Kenntnis und Anwendung) der diagnostischen Vorgehensweise des dynamischen Testens (Dynamic Assessment) von Logopäd:innen in den drei Logopädiebereichen Frühbereich, Schulbereich und klinischer Bereich in der Deutschschweiz. Das Dynamic Assessment ist eine alternative Möglichkeit, schwierig zu testende Klient:innengruppen, wie beispielsweise mehrsprachige Kinder, diagnostisch zu erfassen, ohne sie mit einer Norm vergleichen zu müssen. Aktuell gibt es noch keine käuflichen Diagnostiken, die dynamisch testen. Das ist ein Hinweis darauf, dass sich diese diagnostische Vorgehensweise im Therapiealltag noch nicht etabliert hat. Dies bestätigt die quantitative Analyse der Daten der im Rahmen dieser Arbeit durchgeführten Online-Befragung von 86 Logopäd:innen. Die Mehrheit der Logopäd:innen, welche das dynamische Testen kennen, wenden es in ihrem Therapiealltag nicht an. Die Auswertungen bestätigen, dass lediglich im Schulbereich das Dynamic Assessment angewendet wird. Weiter wird in der Arbeit aufgezeigt, welchen Einfluss die Berufserfahrung auf den Kenntnisstand hat. Ferner werden Gründe für und gegen die Verwendung des dynamischen Testens bzw. Vor- und Nachteile analysiert und die diagnostische Vorgehensweise von Logopäd:innen ohne Kenntnis des dynamischen Testens beschrieben.

Genetic structure, gene flow and local adaptation in the interior spruce hybrid zone

description: Natural hybrid zones provide a great opportunity to study the evolutionary relationships between closely related species. I have combined ten microsatellites (SSR) and 311 single nucleotide polymorphism (SNP) markers with quantitative data to investigate the genetic structure, interspecific gene flow and adaptation of the economically and ecologically important Picea glauca (white spruce) x P. engelmannii (Engelmann spruce) hybrid zone in western North America. Climate modelling and paleoclimate analysis was used to study the historical evolutionary relationships between hybridizing species; and to predict future patterns of genetic variation in the zone. This modelling suggests these species may have been in contact for as long as 21,000 years. Current levels of admixture and introgression are extensive, as suggested by both the SSR and SNP analyses, with populations showing elevational and latitudinal unimodal clines in admixture. Hybrids occupy intermediate environments in the zone and show a higher genetic contribution from Engelmann spruce than from white spruce on average. Despite a long history of interspecific gene flow, pure species and hybrids are adapted to different environments. Results of the quantitative analysis based on long-term data on growth and survival, as well as bud phenology and cold hardiness, indicate that the white x Engelmann spruce hybrid zone is maintained by adaptation to the length of growing seasons and the persistence of the snowpack (exogenous selection), in which hybrids are fitter than pure species in intermediate environments, fitting the "Bounded hybrid superiority" model of hybrid zone maintenance. I identified 12 outlier SNPs among the 311 SNPs; these were genes responsible for carbohydrate metabolism, signal transduction and transcription factors. These results have significant implications for forest management and breeding of spruce species in British Columbia, where this species complex is managed as one species without considering the complexity in population structure and adaptive differences between pure species and hybrids.

description: Introduction: In 2019 the Royal College of Physicians and Surgeons of Canada added educational experiences in MSUS to the core competencies in rheumatology as an optional training experience. Many Canadian rheumatology programs offer MSUS training for residents, but there is currently no national ultrasound curriculum in Canada outside of externally available courses. Objectives: This thesis had two objectives. Objective one was to explore how educators prioritize competencies while developing educational content for a rheumatology MSUS curriculum. Objective two was to define the expert consensus recommendations for MSUS in Canadian post-graduate rheumatology training programs. Methods: To address objective one, we invited educators with rheumatology MSUS expertise to participate in a modified nominal group technique (NGT) with a sequential mixed methods design. For objective two, we assembled a MSUS working group including educators with rheumatology MSUS expertise, rheumatology residents, and rheumatology program directors. We used a three-stage consensus design including a modified NGT, modified Delphi technique, and structured online focus group to establish consensus among the MSUS working group on MSUS competencies that should be included in a national rheumatology resident curriculum. Results: We identified seven themes that represent key elements educators consider when prioritizing competencies during the curriculum development process, which balance two key factors: clinical utility and learnability. We used these themes to develop a conceptual framework that can be used to help guide educators when curricular content must be prioritized. For the consensus recommendations, key rheumatology MSUS stakeholders agreed that it should be mandatory for all Canadian post-graduate rheumatology trainees to learn basic ultrasound skills; how to perform a focused MSUS exam of the hands, wrists, and feet for features of inflammatory arthritis; and perform a limited MSUS exam of the knee and ankle to identify a joint effusion. Conclusion: This thesis used a hybrid of consensus methods to advance MSUS education in Canadian post-graduate rheumatology training programs. We hope that this work can contribute to the goal of a national MSUS curriculum for all Canadian post-graduate rheumatology trainees.
Correlating lepton mixing angles and mixing matrix with Wolfenstein parameters

description: Inspired by a new relation $θ_{13}^{\rm PMNS}={θ_C}/{\sqrt{2}}$ observed from the relatively large $θ_{13}^{\rm PMNS}$, we find that the combination of this relation with the quark-lepton complementarity and the self-complementarity results in correlations of the lepton mixing angles with the quark mixing angles. We find that the three mixing angles in the PMNS matrix are all related to the Wolfenstein parameter $λ$ in the quark mixing, so they are also correlated. Consequently, the PMNS matrix can be parameterized by $λ$, A, and a Dirac CP-violating phase $δ$. Such parametrizations for the PMNS matrix have the same explicitly hierarchical structure as the Wolfenstein parametrization for the CKM matrix in the quark mixing, and the bimaximal mixing pattern is deduced at the leading order. We also discuss implications of these phenomenological relations in parametrizations.
