description: A medium which is an isotropic chiral medium from the perspective of a co-moving observer is a Faraday chiral medium (FCM) from the perspective of a non-co-moving observer. The Tellegen constitutive relations for this FCM are established. By an extension of the Beltrami field concept, these constitutive relations are exploited to show that planewave propagation is characterized by four generally independent wavenumbers. This FCM can support negative phase velocity at certain translational velocities and with certain wavevectors, even though the corresponding isotropic chiral medium does not. The constitutive relations and Beltrami--like fields are also used to develop a convenient spectral representation of the dyadic Green functions for the FCM.

description: The correlation between ex situ electronic conductivity, oxygen vacancy content, flat-band potential (Efb), and the oxygen evolution reaction (OER) activity for a wide range of perovskite compositions are investigated experimentally and theoretically. It is found that all of these parameters can affect the OER activity; however, none of them alone play a crucial role in determining the electrocatalytic activity. The correlation of one single physicochemical property with the OER activity always presents deviation points, indicating that a limitation does exist for such 2-dimensional correlations. Nevertheless, these deviations can be explained considering other physicochemical properties and their correlation with the OER activity. Hence, this work aims in simultaneously linking the OER activity with several physicochemical materials properties. The concept of the OER/multidescriptor relationship represents a significant advancement in the search and design of highly active oxygen evolution catalysts, in the quest for efficient anodes in water electrolyzers.

description: The Rational Polynomial Camera (RPC) model can be used to describe a variety of image acquisition systems in remote sensing, notably optical and Synthetic Aperture Radar (SAR) sensors. RPC functions relate 3D to 2D coordinates and vice versa, regardless of physical sensor specificities, which has made them an essential tool to harness satellite images in a generic way. This article describes a terrain-independent algorithm to accurately derive a RPC model from a set of 3D-2D point correspondences based on a regularized least squares fit. The performance of the method is assessed by varying the point correspondences and the size of the area that they cover. We test the algorithm on SAR and optical data, to derive RPCs from physical sensor models or from other RPC models after composition with corrective functions.

description: In the context of non-relativistic quantum mechanics, we investigated Shannon's entropy of a non-Hermitian system to understand how this quantity is modified with the cyclotron frequency. Subsequently, we turn our attention to the construction of an ensemble of these spinless particles in the presence of a uniform magnetic field. Then, we study the thermodynamic properties of the model. Finally, we show how Shannon's entropy and thermodynamic properties are modified with the action of the magnetic field.

description: Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open ring, Fano line shapes are observed in the current through the ring, when the electron number in the dot changes by one. The symmetry of the Fano resonances is found to depend on the magnetic flux penetrating the area of the ring and on the strength of the ring-dot coupling. At temperatures above T=0.65 K the Fano effect disappears while the Aharonov-Bohm interference in the ring persists up to T=4.2 K. Good agreement is found between these experimental observations and a single channel scattering matrix model including decoherence in the dot.

description: Der Universalismus steht zunehmend unter Imperialismusverdacht – auch in der Geschlechterforschung. Allzu oft wurde er für fragwürdige Zwecke instrumentalisiert. Beredtes Beispiel ist der vor wenigen Monaten mit dem Abzug der NATO-Truppen zu Ende gegangene Afghanistankrieg. Als dieser vor 20 Jahren begann, wurden zu seiner Rechtfertigung nicht zuletzt Frauen- und Menschenrechte angeführt, die von der damaligen Taliban-Regierung in der Tat verletzt wurden. Leider waren dann, wie in Kriegen üblich, auch die westlichen Streitkräfte wenig zimperlich, Folter und zivile Opfer eingeschlossen.

Nun sind die Taliban zurück an der Macht und die vormals beklagten Verletzungen grundlegender Frauen- und Menschenrechte erneut an der Tagesordnung – und zwar ohne, dass es die heimgekehrten Ex-Besatzer nachhaltig zu stören scheint. Der Umgang mit den einstigen Ortskräften und ihren Familien, von denen Tausende schlicht im Stich gelassen wurden, spricht mehr als Bände, auch wenn es zivilgesellschaftliche Ausnahmen gibt, die Luftbrücke Kabul etwa oder das Patenschaftsnetzwerk Afghanische Ortskräfte e. V., und wenn die eine oder andere Protestnote geschrieben wird.

description: We have considered two classical lattice-gas models, consisting of particles that carry multicomponent magnetic momenta, and associated with a two-dimensional square lattices; each site can host one particle at most, thus implicitly allowing for hard-core repulsion; the pair interaction, restricted to nearest neighbors, is ferromagnetic and involves only two components. The case of zero chemical potential has been investigated by Grand--Canonical Monte Carlo simulations; the fluctuating occupation numbers now give rise to additional fluid-like observables in comparison with the usual saturated--lattice situation; these were investigated and their possible influence on the critical behaviour was discussed. Our results show that the present model supports a Berezinskii-Kosterlitz-Thouless phase transition with a transition temperature lower than that of the saturated lattice counterpart due to the presence of ``vacancies''; comparisons were also made with similar models studied in the literature.

description: Dwarf spheroidal galaxies (dSphs) have been extensively investigated in the Local Group, but their low luminosity and surface brightness make similar work in more distant galaxy groups challenging. Modern instrumentation unlocks the possibility of scrutinizing these faint systems in other environments, expanding the parameter space of group properties. We use MUSE spectroscopy to study the properties of 14 known or suspected dSph satellites of Cen A. Twelve targets are confirmed to be group members based on their radial velocities. Two targets are background galaxies at 50 Mpc: KK 198 is a face-on spiral galaxy, and dw1315-45 is an ultra-diffuse galaxy with an effective radius of 2300 pc. The 12 confirmed dSph members of the Cen A group have old and metal-poor stellar populations and follow the stellar metallicity-luminosity relation defined by the dwarf galaxies in the Local Group. In the three brightest dwarf galaxies (KK 197, KKs 55, and KKs 58), we identify globular clusters, as well as a planetary nebula in KK 197, although its association with this galaxy and/or the extended halo of Cen A is uncertain. Using four discrete tracers, we measure the velocity dispersion and dynamical mass of KK 197. This dSph appears dark matter dominated and lies on the radial acceleration relation of star-forming galaxies within the uncertainties. It also is consistent with predictions stemming from modified Newtonian dynamics (MOND). Surprisingly, in the dwarf KK 203 we find an extended Halpha ring. Careful examination of Hubble Space Telescope photometry reveals a very low level of star formation at ages between 30-300 Myr. The Halpha emission is most likely linked to a 40 Myr old supernova remnant, although other possibilities for its origin cannot be entirely ruled out.

description: This thesis explores the Tiny House Village Model as a critical framework for developing intentional homeless communities, or IHCs, that better serve the housing, service, and social needs of those experiencing homelessness. This research examines different approaches to land ownership, land-use & zoning regulations, and financing tools that allow transitional congregate shelters and affordable tiny house villages to be more easily constructed on land within the urban area. Additionally, this research considers the various aspects of housing and community design that can be used in these projects to give planning and development professionals an idea of how to best create these communities to allow a positive transitional and permanent housing experience. Using lessons from seven case studies across Oregon, Washington, and Texas, this research offers a resource guide for planners and housing leaders in the Austin community to use when thinking about innovative and human-centered approaches to housing the city’s homeless population. This research focuses on the City of Austin and addresses how local government can best support these projects by enacting policies and regulations that provide legal grounding, support, and recognition of this type of housing infrastructure. Results include strategies for creating IHCs through existing and proposed land ownership, regulatory, and financing tools to give the City of Austin the best chance of creating alternative housing types for the unhoused population

description: In modern social media platforms, an effective content recommendation should benefit both creators to bring genuine benefits to them and consumers to help them get really interesting content. To address the limitations of existing methods for social recommendation, we propose Social Explorative Attention Network (SEAN), a social recommendation framework that uses a personalized content recommendation model to encourage personal interests driven recommendation. SEAN has two versions: (1) SEAN-END2END allows user's attention vector to attend their personalized interested points in the documents. (2) SEAN-KEYWORD extracts keywords from users' historical readings to capture their long-term interests. It is much faster than the first version, more suitable for practical usage, while SEAN-END2END is more effective. Both versions allow the personalization factors to attend to users' higher-order friends on the social network to improve the accuracy and diversity of recommendation results. Constructing two datasets in two languages, English and Spanish, from a popular decentralized content distribution platform, Steemit, we compare SEAN models with state-of-the-art collaborative filtering (CF) and content based recommendation approaches. Experimental results demonstrate the effectiveness of SEAN in terms of both Gini coefficients for recommendation equality and F1 scores for recommendation accuracy.

description: Jon walks into a bar and orders a Manhattan. The bartender asks him for twenty USD’s, he coughs them up, and sulks off with his cocktail. Clearly, this everyday interaction both is and involves social phenomena. Although there are many kinds of social phenomena, it’s quite plausible that one kind is fundamental relative to the rest: social groups. Jon is a patron and, so, an ‘element’ of a particular group – a business – of which his cocktail is a product. Moreover, the twenty USD’s he coughs up are printed by one group, the Bureau of Printing and Engraving, and its value is underwritten by another group, the United States Treasury. Even the advertisements, the swank, and the wealth inequality that partly account for Jon’s decision to pay twenty USD’s for a cocktail are deeply related to groups. Advertisements come from agencies, swank from social practices that we practice, and wealth inequality from institutions that systematically disadvantage by groups of folks. Social reality is remarkably complex, but what we do as patrons, producers, and practitioners – how we function as denizens – are at the heart of it. As a result, the question arises: what are groups? In this dissertation, I try to answer this question.

description: Robotics can be defined as the connection of perception to action. Taking this further, this project aims to drive a robot using an automated computer vision embedded system, connecting the robot's vision to its behavior. In order to implement a color recognition system on the robot, open source tools are chosen, such as Processing language, Android system, Arduino platform and Pixy camera. The constraints are clear: simplicity, replicability and financial viability. In order to integrate Robotics, Computer Vision and Image Processing, the robot is applied on a typical mobile robot's issue: line following. The problem of distinguishing the path from the background is analyzed through different approaches: the popular Otsu's Method, thresholding based on color combinations through experimentation and color tracking via hue and saturation. Decision making of where to move next is based on the line center of the path and is fully automated. Using a four-legged robot as platform and a camera as its only sensor, the robot is capable of successfully follow a line. From capturing the image to moving the robot, it's evident how integrative Robotics can be. The issue of this paper alone involves knowledge of Mechanical Engineering, Electronics, Control Systems and Programming. Everything related to this work was documented and made available on an open source online page, so it can be useful in learning and experimenting with robotics.

description: Cities nationwide are grappling with pressing challenges related to affordable housing, climate change, and discriminatory zoning practices. One potential solution at the intersection of these issues is Missing Middle Housing, a term coined by Daniel Parolek in 2010. This housing typology is known for its ability to encourage compact, walkable urban development that was more prevalent in US cities decades ago. With Parolek’s reimagination of housing types with two to nineteen units, cities across the country have begun updating their zoning codes to be more accommodating of Missing Middle Housing. However, Parolek’s narrow definition excludes several housing types that could offer higher densities and contribute to walkable urban neighborhoods at a time where cities need more housing. This report aims to expand the definition of Missing Middle Housing by examining three case studies of housing types that fit within this expanded definition. These case studies highlight a range of urban housing, already existing within cities, which promote the same density and walkability Missing Middle Housing does, without the strict adherence to the existing form of single-family neighborhoods promoted by Parolek. These case studies are then utilized in three future development scenarios in Austin, Texas, to display the potential of incorporating a broader range of housing types in urban planning and development efforts. By considering an expanded definition of Missing Middle Housing, cities can address multiple challenges simultaneously and promote more inclusive and sustainable urban development

Knowlegde of all aspects of the beauty and charm production process, viz. the parton density functions of colliding hadrons, the hard scatter, and the fragmentation of the quarks into hadrons, can aid LHC experimentation. This short write-up concentrates on possible influences HERA data can have and on the current status (and history) of beauty production from both HERA and Tevatron experiments. In general, next-to-leading order QCD gives a reasonable description of beauty production although some regions of phase space such as low p_T show indications of differences.

The dual nature of identity fusion : a unifying force or a source of division?

description: Identity plays a key role in determining what matters to people and what they are willing to fight for. Identity fusion, an extreme form of identification where one's personal self is unified with an abstraction (a group, cause, or other individual), predicts extreme behaviors in defense of the target of fusion. In the face of a perceived threat to one's fused group, fused individuals often react harshly against the source of the threat, such as by endorsing violence against outgroups. However, identity fusion does not necessitate hostility toward outgroups. Indeed, some work suggests that in the absence of threat, fused individuals can be benign towards outgroup members. The demarcation between when fusion might have prosocial outcomes for the larger society as opposed to antisocial outcomes against perceived outgroup members is in need of further exploration, especially in the highly divided modern American political landscape. Therefore, the purpose of this dissertation is to further investigate the nature of identity fusion and when fusion might have a unifying influence as opposed to a divisive one. Across four lines of research, the current work examined (1) whether identity fusion is a more potent predictor of extreme behaviors in the political sphere than rival constructs such as moral convictions or sacred values (Chapter 2), (2) whether fusion with a partisan identity such as a political party positively predicts extreme behaviors that could potentially increase the power of the partisan group, but may be detrimental to the larger society (Chapters 3-5), and (3) whether fusion with a superordinate group such as one's nation or even all of humanity negatively predicts behaviors that may harm the larger society, even if such behaviors might myopically benefit one's political party. Findings from Chapter 2 provide evidence that identity fusion is the strongest predictor of extreme behavior on behalf of a political cause. Findings from Chapters 3-5 show that fusion with a political party or candidate positively predicts support for authoritarian actions against the opposing party, while fusion with the US negatively predicts the same authoritarianism. In Chapter 5, writing about a patriotic memory increased fusion with the US among Republicans, and fusion with the US marginally interacted with the patriotic prime manipulation to predict decreased support for authoritarianism among both Republicans and Democrats. Taken together, these findings shed valuable insight into the dual nature of identity fusion as both a unifying force and a source of division.

description: In this work, we present a methodology for monitoring man-made, construction-like activities in low-resolution SAR imagery. Our source of data is the European Space Agency Sentinel-l satellite which provides global coverage at a 12-day revisit rate. Despite limitations in resolution, our methodology enables us to monitor activity levels (i.e. presence of vehicles, equipment) of a pre-defined location by analyzing the texture of detected SAR imagery. Using an exploratory dataset, we trained a support vector machine (SVM), a random binary forest, and a fully-connected neural network for classification. We use Haralick texture features in the VV and VH polarization channels as the input features to our classifiers. Each classifier showed promising results in being able to distinguish between two possible types of construction-site activity levels. This paper documents a case study that is centered around monitoring the construction process for oil and gas fracking wells.

description: This paper proposes a system for automatic surface volume monitoring from time series of SkySat pushframe imagery. A specific challenge of building and comparing large 3D models from SkySat data is to correct inconsistencies between the camera models associated to the multiple views that are necessary to cover the area at a given time, where these camera models are represented as Rational Polynomial Cameras (RPCs). We address the problem by proposing a date-wise RPC refinement, able to handle dynamic areas covered by sets of partially overlapping views. The cameras are refined by means of a rotation that compensates for errors due to inaccurate knowledge of the satellite attitude. The refined RPCs are then used to reconstruct multiple consistent Digital Surface Models (DSMs) from different stereo pairs at each date. RPC refinement strengthens the consistency between the DSMs of each date, which is extremely beneficial to accurately measure volumes in the 3D surface models. The system is tested in a real case scenario, to monitor large coal stockpiles. Our volume estimates are validated with measurements collected on site in the same period of time.
Improving Canadian teachers' assessment literacy and decision-making through self-directed professional development
Creators: Bulut, Okan
Publisher: name: University of Alberta Library
Year: 2022

SSHRC IG awarded 2023: Educational assessment can be one of the most productive forces for student learning in classrooms or one of the most destructive. The deciding factor is whether teachers can make assessment decisions that can engage and motivate students and enhance their learning. Although new provincial and territorial assessment policies consistently promote a student-centred view of assessment, the lack of assessment literacy continues to be a major drawback that prevents teachers from promoting equitable learning and improving student achievement. This SSHRC study tackles this gap in teacher practice by analysing Canadian teachers' current assessment practices to develop a self-directed professional development (PD) program to improve pre-service and in-service teachers' assessment literacy. The ultimate goal of the PD program is to ensure a productive future for assessment in Canadian schools, one that reduces inequities in learning and benefits all students.

description: We report on size-dependent properties of dithallium selenide, Tl2Se. We have carried out a comparative nuclear magnetic resonance (NMR) study of Tl2Se nanorods and bulk samples, measuring NMR spectra and spin-lattice relaxation rate of 203Tl and 205Tl isotopes. Though bulk Tl2Se was reported to be a metal, the Korringa-like spin-lattice relaxation behavior is observed only at low temperatures and is transformed to an activation regime above ~200 K. This finding is interpreted assuming a two-band model in the semimetallic compound. Our measurements show significant difference in the Knight shift and indirect nuclear exchange coupling for the bulk and nanorod Tl2Se samples, reflecting noticeable distinction in their electronic structure. At that, Tl2Se nanorods are semiconductors and exhibit a characteristic activation behavior in the spin-lattice relaxation rate due to the thermal excitation of carriers to the conduction band. The obtained size dependence of the Tl2Se properties is interpreted in terms of the semimetal-semiconductor transformation due to the quantum confinement.

Creators: Symonds-Brown, Holly
Publisher: name: University of Alberta Library
Year: 2023

SSHRC IDG awarded 2023: People living with dementia are the fastest growing group of disabled people in the world. Currently at least 500,000 Canadians are diagnosed with dementia, a number expected to triple by the year 2050. Despite increased awareness of the need to support social inclusion and citizenship for people living with dementia and their families, we know relatively little about how they make their way through their worlds, find places of belonging and adjust over time to ‘stay in the life’ of their communities. Dementia shapes people’s mobility within their social and material environments and demands new adjustments, strategies, technologies, and routines in everyday life. This ethnographic study will begin a process of developing knowledge about how mobility – or the freedom to move through, and participate in, the world – is shaped and supported over time for people living with dementia and their families at home.

Wellbeing

description: Loneliness, a pressing public health issue, remains prevalent in modern societies, with the Gen Z population experiencing the highest levels (Cigna, 2018). The COVID-19 pandemic, leading to social distancing measures and the widespread adoption of remote learning and working, has further aggravated the feelings of disconnection. The current study examines the impact of social video gaming, social presence during gameplay, gamer identity, and perceived group membership on perceived psychological distress, loneliness, social connectedness, and social support. Findings show social gaming is negatively correlated with emotional loneliness, while gamer identity is positively associated. Perceived group membership is negatively linked to social loneliness. Gamer identity negatively correlates with social connectedness, while negative emotions towards other players through social presence are positively linked to connectedness. Finally, self-investment positively associates with perceived social support. Implications and future research are discussed.

description: Gaussian Processes (GPs) are a class of kernel methods that have shown to be very useful in geoscience applications. They are widely used because they are simple, flexible and provide very accurate estimates for nonlinear problems, especially in parameter retrieval. An addition to a predictive mean function, GPs come equipped with a useful property: the predictive variance function which provides confidence intervals for the predictions. The GP formulation usually assumes that there is no input noise in the training and testing points, only in the observations. However, this is often not the case in Earth observation problems where an accurate assessment of the instrument error is usually available. In this paper, we showcase how the derivative of a GP model can be used to provide an analytical error propagation formulation and we analyze the predictive variance and the propagated error terms in a temperature prediction problem from infrared sounding data.

description: While Traumatic brain injury (TBI) is the leading cause of disability in children, it is unclear how early life stress (ELS) may act as a determinant of long-term recovery in brain-injured children. A murine model of ELS preceding TBI at postnatal day (P)21 addressed the following: regionally specific acute pathogenesis of the hippocampus after ELS+TBI, are these early changes predictive of hippocampal damage and impairment at adulthood. Males and females were exposed to ELS (P2-9) with the limited bedding nestlet (LBN) model, randomized to TBI or sham, and euthanized at P22 or adulthood. At P22, ELISAs revealed an upregulation of IL1B, IL-6, TNFα, and IFNγ in both sexes after injury. ELS+TBI elevated IL-1B, IL-10, TNFα, and IFNγ in males compared to TBI. Iba-1 and caspase-3 were evaluated in hippocampal subregions. While TBI increased microglial density in both sexes, ELS+TBI increased microglial density in male CA2 and CA3 but only in the CA3 in females compared to TBI. Quantification of caspase-3 revealed apoptosis in males and females after TBI. ELS + TBI increased apoptosis in CA1 and CA3 in males and females compared to TBI. Adulthood learning and memory were assessed with the NOR and Barnes Maze. Compared to TBI, ELS+TBI reduced novelty preference in females and increased path length to target in both sexes. Hippocampal neuron loss after ELS+TBI was evaluated at adulthood. TBI significantly reduced neurons in all subregions; ELS+TBI reduced neurons in the CA1 region in females only. These findings highlight hippocampal vulnerability after ELS+TBI and ELS prior to a TBI may enhance acute pathogenesis in males. Correlation matrices determined hippocampal acute pathogenesis is predictive of neuronal loss at adulthood and is associated with learning and memory impairments. Males and females were assessed for all outcomes. Both sexes showed similar vulnerability to secondary pathogenesis following TBI and adulthood impairments in learning and memory; males showed greater vulnerability to acute pathogenesis and females showed greater vulnerability to adulthood outcomes. These findings may advocate for opportunities to tailor therapies specific to each sex. Thus, developing pre-clinical biomarkers to predict long-term recovery may continue to bolster care management.
Re-reading the History of Recreation and Sport: An Online Learning Module
Creators: Tink, Lisa N.
Publisher: name: University of Alberta Library
Year: 2024

SSHRC CG awarded 2024: The purpose of this project is to develop a free online learning module for established and emerging professionals (i.e., scholars, students, practitioners, and policymakers) working in recreation, sport, physical activity, leisure, and other movement cultures. Based on research from the book titled "Fit to be Canadian? The Recreation Industrial Complex in Canada," the module will include 16 interrelated lessons. Collectively, these lessons will provide a re-reading of recreation/sport history by demonstrating how Indigenous genocide, racist immigration policy, and eugenic social programs) have shaped, and continue to shape, our recreation and sporting environments (e.g., playgrounds, swimming pools, urban parks, municipal recreation/sport centres). The module will be developed in partnership with the InMotion Network, an Albertan non-profit organization, to act as a starting point for creating more just, equitable, and meaningful opportunities.
Spin-dependent electronic structure of transition-metal atomic chains adsorbed on single-wall carbon nanotubes

description: We present a systematic study of the electronic and magnetic properties of transition-metal (TM) atomic chains adsorbed on the zigzag single-wall carbon nanotubes (SWNTs). We considered the adsorption on the external and internal wall of SWNT and examined the effect of the TM coverage and geometry on the binding energy and the spin polarization at the Fermi level. All those adsorbed chains studied have ferromagnetic ground state, but only their specific types and geometries demonstrated high spin polarization near the Fermi level. Their magnetic moment and binding energy in the ground state display interesting variation with the number of $d-$electrons of the TM atom. We also show that specific chains of transition metal atoms adsorbed on a SWNT can lead to semiconducting properties for the minority spin-bands, but semimetallic for the majority spin-bands. Spin-polarization is maintained even when the underlying SWNT is subjected to high radial strain. Spin-dependent electronic structure becomes discretized when TM atoms are adsorbed on finite segments of SWNTs. Once coupled with non-magnetic metal electrodes, these magnetic needles or nanomagnets can perform as spin-dependent resonant tunnelling devices. The electronic and magnetic properties of these nanomagnets can be engineered depending on the type and decoration of adsorbed TM atom as well as the size and symmetry of the tube. Our study is performed by using first-principles pseudopotential plane wave method within spin-polarized Density Functional Method.

description: Large models and enormous data are essential driving forces of the unprecedented successes achieved by modern algorithms, especially in scientific computing and machine learning. Nevertheless, the growing dimensionality and model complexity, as well as the non-negligible workload of data pre-processing, also bring formidable costs to such successes in both computation and data aggregation. As the deceleration of Moore's Law slackens the cost reduction of computation from the hardware level, fast heuristics for expensive classical routines and efficient algorithms for exploiting limited data are increasingly indispensable for pushing the limit of algorithm potency. This thesis explores some of such algorithms for fast execution and efficient data utilization. 1. From the computational efficiency perspective, we design and analyze fast randomized low-rank decomposition algorithms for large matrices based on “matrix sketching”, which can be regarded as a dimension reduction strategy in the data space. These include the randomized pivoting-based interpolative and CUR decomposition discussed in Chapter 2 and the randomized subspace approximations discussed in Chapter 3. 2. From the sample efficiency perspective, we focus on learning algorithms with various incorporations of data augmentation that improve generalization and distributional robustness provably. Specifically, Chapter 4 presents a sample complexity analysis for data augmentation consistency regularization where we view sample efficiency from the lens of dimension reduction in the function space. Then in Chapter 5, we introduce an adaptively weighted data augmentation consistency regularization algorithm for distributionally robust optimization with applications in medical image segmentation.
Thinking Historically for Canada's Future
Creators: Peck, Carla
Publisher: name: University of Alberta Library
Year: 2016

SSHRC PG LOI|Stage 1 awarded 2016; Stage 2 not successful: Canada has long struggled with questions of national identity as a result of contested ground over the stories told about its past. Struggles over sovereignty by Quebec Francophones and Indigenous peoples, as well as the continued diversification of the population, mean that a new approach to history education is needed. Citizens face a level of political, social, and cultural complexity that demands, among other things, a solid grounding in the past. Understanding and responding to shared yet often-unacknowledged colonial histories is necessary for reconciliation, social justice, and judicious civic engagement of all Canadians. The proposed partnership will bring together various constituencies involved in history education including academic historians, history education scholars working in faculties of education, Indigenous scholars, graduate students, museum educators, teachers, ministries of education, policy makers, and local, provincial and national history/heritage organizations.
