Sharing Métis women’s stories about moon time and colonial body shame through visiting and berry picking in Buttertown, Alberta
Creators: name: Paul, Hanna M.
Publisher: name: University of British Columbia
Year: 2023

description: Indigenous women’s bodies have been the subject of extractive study through western scholarship, yet Métis women’s bodies and knowledge around experiences with Métis moon time (menstruation) has received little to no attention. I approach my Master’s thesis through the weaving of emergent Indigenous feminist theory, decolonial theory and methods, and Métis methodologies. My project focuses upon: (1) the historical legacy of western menstrual teachings and its effect on Indigenous women and youth’s body images; (2) how Métis teachings can create space for knowing, healing, and identity in my community; and (3) how Métis women’s teachings and bodily connection can help reimagine and dream into existence self-image futurisms for Buttertown, Alberta. Current literature only addresses how colonial and patriarchal concepts of menstruation affect Métis women and young girls (Baldy 2017). Beyond the literature, there is no specific research within Métis communities, specifically Buttertown, near Fort Vermilion, Alberta, which stems from internalized patriarchal frameworks and principles that affect the well-being of women and youth during this monthly ceremony. This project begins with my own experience and with the Métis community of Buttertown. I use autoethnography, Métis storying, Métis oral history, Métis historical archives, and most importantly the social practice of visiting (Flaminio et al. 2020; Gaudet 2018). My metaphoric methodology of saskatoon berry picking grounds my research in Buttertown and parallels my Indigenous research approach to the berry picking process. Through this project, I gain new insights into how reconnection and re-emergence of Métis moon time teachings links to healing and Indigenous concepts of well-being (Gaudet & Caron-Bourbonnais 2015; Zinga & Styres 2013).
A viable relativistic scalar theory of gravitation

description: We build a self-consistent relativistic scalar theory of gravitation on a flat Minkowski spacetime from a general field Lagrangian. It is shown that, for parameters that satisfy the Equivalence Principle, this theory predicts the same outcome as general relativity for every classical solar-system test. This theory also admits gravitational waves that propagate at the speed of light, and the gravitational radiation energy loss in a binary system is shown to be very similar to the GR prediction. We then analyze the strong gravity regime of the theory for a spherically symmetric configuration and find that there is an effective "singularity" near the Schwarzschild radius. The main goal of this work is to show that, contrary to what is commonly believed, there are relativistic scalar theories of gravitation defined on a Minkowski spacetime that are not ruled out by the classical solar system tests of general relativity.

description: We recently studied neutrinos flavor oscillations in vacuum within conformal coupling models. In this paper, we extend that analysis by investigating neutrino flavor oscillations inside matter within a general conformal coupling scenario. We first derive the general formula for the flavor transition probability inside matter in arbitrary static and spherically symmetric spacetimes. The modified resonance formula of the MSW effect is derived and the corresponding adiabaticity parameter of the effect is extracted. An application of our results to the case of two-flavor neutrinos within the well-known chameleon and symmetron conformal coupling models is made.

LwPosr: Lightweight Efficient Fine-Grained Head Pose Estimation
Creators: name: Dhingra, Naina
Publisher: name: arXiv
Year: 2022
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: This paper presents a lightweight network for head pose estimation (HPE) task. While previous approaches rely on convolutional neural networks, the proposed network \textit{LwPosr} uses mixture of depthwise separable convolutional (DSC) and transformer encoder layers which are structured in two streams and three stages to provide fine-grained regression for predicting head poses. The quantitative and qualitative demonstration is provided to show that the proposed network is able to learn head poses efficiently while using less parameter space. Extensive ablations are conducted using three open-source datasets namely 300W-LP, AFLW2000, and BIWI datasets. To our knowledge, (1) \textit{LwPosr} is the lightest network proposed for estimating head poses compared to both keypoints-based and keypoints-free approaches; (2) it sets a benchmark for both overperforming the previous lightweight network on mean absolute error and on reducing number of parameters; (3) it is first of its kind to use mixture of DSCs and transformer encoders for HPE. This approach is suitable for mobile devices which require lightweight networks.

description: Kinetic inductances of superconducting nanostrips with a meander pattern are theoretically investigated based on the London model, and the effect of the current crowding at the turns of the nanostrips is considered. The complex current approach is developed for analytical investigation of the kinetic inductance of nanostrips with turns for thin $d<λ$ and narrow $w\ll λ^2/d$ superconducting strips, where $d$ is the strip thickness, $w$ is the strip width, and $λ$ is the London penetration depth. We show that the current distribution in superconducting nanostrips of $wd\llλ^2$ is identical to that in normal conducting nanostrips of $wd\llδ^2/2$, where $δ$ is the skin depth, and the dependence of the kinetic inductance on the nanostrip geometry is identical to that of the normal resistance. Effects of the edge defects of superconducting strips upon the kinetic inductance are also considered.

HeadPosr: End-to-end Trainable Head Pose Estimation using Transformer Encoders
Creators: name: Dhingra, Naina
Publisher: name: arXiv
Year: 2022
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: In this paper, HeadPosr is proposed to predict the head poses using a single RGB image. \textit{HeadPosr} uses a novel architecture which includes a transformer encoder. In concrete, it consists of: (1) backbone; (2) connector; (3) transformer encoder; (4) prediction head. The significance of using a transformer encoder for HPE is studied. An extensive ablation study is performed on varying the (1) number of encoders; (2) number of heads; (3) different position embeddings; (4) different activations; (5) input channel size, in a transformer used in HeadPosr. Further studies on using: (1) different backbones, (2) using different learning rates are also shown. The elaborated experiments and ablations studies are conducted using three different open-source widely used datasets for HPE, i.e., 300W-LP, AFLW2000, and BIWI datasets. Experiments illustrate that \textit{HeadPosr} outperforms all the state-of-art methods including both the landmark-free and the others based on using landmark or depth estimation on the AFLW2000 dataset and BIWI datasets when trained with 300W-LP. It also outperforms when averaging the results from the compared datasets, hence setting a benchmark for the problem of HPE, also demonstrating the effectiveness of using transformers over the state-of-the-art.

description: We study the acceleration of charged particles by ultra-relativistic shocks using test-particle Monte-Carlo simulations. Two field configurations are considered: (i) shocks with uniform upstream magnetic field in the plane of the shock, and (ii) shocks in which the upstream magnetic field has a cylindrical geometry. Particles are assumed to diffuse in angle due to frequent non-resonant scattering on small-scale fields. The steady-state distribution of particles' Lorentz factors is shown to approximately satisfy $dN/dγ\propto γ^{-2.2}$ provided the particle motion is scattering dominated on at least one side of the shock. For scattering dominated transport, the acceleration rate scales as $t_{\rm acc}\propto t^{1/2}$, though recovers Bohm scaling $t_{\rm acc}\propto t$ if particles become magnetised on one side of the shock. For uniform field configurations, a limiting energy is reached when particles are magnetised on both sides of the shock. For the cylindrical field configuration, this limit does not apply, and particles of one sign of charge will experience a curvature drift that redirects particles upstream. For the non-resonant scattering model considered, these particles preferentially escape only when they reach the confinement limit determined by the finite system size, and the distribution approaches the escapeless limit $dN/dγ\propto γ^{-1}$. The cylindrical field configuration resembles that expected for jets launched by the Blandford $\&$ Znajek mechanism, the luminous jets of AGN and GRBs thus provide favourable sites for the production of ultra-high energy cosmic rays.

description: Memory loss is not always viewed purely as a contingent neurobiological process present in an ageing population; rather, it is frequently related to larger societal issues and political debates. This edited volume examines how different media and genres – novels, auto/biographical writings, documentary as well as fictional films and graphic memoirs – represent dementia for the sake of critical explorations of memory, trauma and contested truths. In ten analytical chapters and one piece of graphic art, the contributors examine the ways in which what might seem to be the individual, ahistorical diseases of dementia are used in contemporary cultural texts to represent and respond to violent historical and political events – ranging from the Holocaust to postcolonial conditions – all of which can prove difficult to remember. Combining approaches from literary studies with insights from memory studies, trauma studies, anthropology, the critical medical humanities and media, film and comics studies, this volume explores the politics of dementia and incites new debates on cultures of remembrance, while remaining attentive to the lived reality of dementia.

description: It is incontrovertible that, with the ravages inflicted on the world by the Covid-19 pandemic, travel by air has been vastly reduced amidst strict quarantine measures imposed on passengers. The resuscitation of air services to the volume that existed in 2019 will not only take a long time but will also require new approaches to connectivity. Trading in air transport will involve more reliance on digital technology and platforms such as the Internet that would promote communication of data and relevant details of route structures and threats posed thereto. Artificial intelligence and the Internet will be essential in providing data and details in a timely manner for both States and their airlines to take effective measures against the spread of another pandemic, the occurrence of which scientists are saying is probable in the foreseeable future. Against this backdrop of ominous reality, the aviation community has no alternative but to lean heavily on spontaneity in the exchange of information to suspend or terminate air services that connect potential hotspots that are likely to spread a virus which infects a particular city and could settle in other cities that are connected by air. This article inquires into the relevance and applicability of technology and the role that the Internet could play in what some call The New Normal.

description: We used the asymmetric superconducting quantum interference device (SQUID) technique to extract the current phase relation (CPR) of a Josephson junction with a 3D-topological insulator (TI) Bi2Se3 nanobelt as the barrier. The obtained CPR shows deviations from the standard sinusoidal CPR with a pronounced forward skewness. At temperatures below 200 mK, the junction skewness values are above the zero temperature limit for short diffusive junctions. Fitting of the extracted CPR shows that most of the supercurrent is carried by ballistic topological surface states (TSSs), with a small contribution of diffusive channels primarily due to the bulk. These findings are instrumental in engineering devices that can fully exploit the properties of the topologically protected surface states of 3D TIs.

description: Software is a critical aspect of large-scale science, providing essential capabilities for making scientific discoveries. Large-scale scientific projects are vast in scope, with lifespans measured in decades and costs exceeding hundreds of millions of dollars. Successfully designing software that can exist for that span of time, at that scale, is challenging for even the most capable software companies. Yet scientific endeavors face challenges with funding, staffing, and operate in complex, poorly understood software settings. In this paper we discuss the practice of early-phase software architecture in the Square Kilometre Array Observatory's Science Data Processor. The Science Data Processor is a critical software component in this next-generation radio astronomy instrument. We customized an existing set of processes for software architecture analysis and design to this project's unique circumstances. We report on the series of comprehensive software architecture plans that were the result. The plans were used to obtain construction approval in a critical design review with outside stakeholders. We conclude with implications for other long-lived software architectures in the scientific domain, including potential risks and mitigations.

Essays on environmental and social issues
Creators: name: Xiao, Zhanbing
Publisher: name: University of British Columbia
Year: 2023

description: Environmental and social (E&S) issues have attracted increasing attention from academics and practitioners. This thesis is a collection of two essays that examine firms’ efforts in these issues and the relevant value implications. The first essay documents a labor channel of firms’ exposure to climate change and studies how firms respond to climate-induced rising labor costs. I focus on firms’ use of outdoor workers and document two channels through which climate change contributes to rising labor costs: physical risk - lower labor supply and productivity in high temperatures; regulatory risk - governments introducing regulations to protect workers against heat hazards. I find that firms exposed to climate change through the labor channel have higher capital-labor ratios, especially when managers believe in climate change or when jobs are easy to automate. After experiencing shocks to physical (abnormally high temperatures) and regulatory (the adoption of the Heat Illness Prevention Standard (HIPS) in California) risks, high-exposure firms switch to more capital-intensive production functions. These firms also respond by innovating more, especially in technologies facilitating automation and reducing labor costs. Furthermore, labor exposure to climate change impedes job creation and hurts workers’ earnings. Overall, the findings highlight that climate change accelerates automation in occupations exposed to rising temperatures. The second essay provides evidence supporting the cash flow channel through which firms’ E&S investments increase value. Using Safegraph’s daily foot-traffic data at the store level, we find a significant decrease in a firm’s store visits following the firm’s violation of E&S standards. The decrease in visits by more E&S-conscious households is nearly four times greater than that by less E&S-conscious households. The reduction in store visits is associated with a reduction in firm sales. On average, one additional E&S incident is associated with a loss of $19.2 million in more E&S-conscious areas and a loss of $9.6 million in less E&S-conscious areas. The findings imply that good E&S performance can enhance firm value by attracting consumers and increasing sales.

description: While visualizations can carry a vast amount of information compared to text and
are often used for validation, references to data and metadata resulting in these visualizations
are not common. To provide such references, the software plotID provides two key modules
that strive to seamlessly integrate into a generic, Python-based research workflow. The
module tagplot generates or accepts a unique ID and anchors it (visibly) as a reference to
a figure or picture. The module publish exports the figure along with the data, code and
parameters used in its creation into folders named by the reference ID for later reuse. The
tools work to provide aid in research data management with simple base functionality as
opposed to encompassing management frameworks. Later features and improvements will
expand the scope and applicability to other programming environments.

description: The introduction of automated deduction systems in secondary schools face several bottlenecks, the absence of the subject of rigorous mathematical demonstrations in the curricula, the lack of knowledge by the teachers about the subject and the difficulty of tackling the task by automatic means. Despite those difficulties we claim that the subject of automated deduction in geometry can be introduced, by addressing it in particular cases: simple to manipulate by students and teachers and reasonably easy to be dealt by automatic deduction tools. The subject is discussed by addressing four secondary schools geometry problems: their rigorous proofs, visual proofs, numeric proofs, algebraic formal proofs, synthetic formal proofs, or the lack of them. For these problems we discuss a lesson plan to address them with the help of Information and Communications Technology, more specifically, automated deduction tools.

description: According to the textbook definition of a customs union, member states of such a union liberalize mutual trade while they adopt a common external tariff or, more broadly, a common trade policy towards third countries. Likewise, art. XXIV of the GATT stipulates that “substantially the same duties and other regulations of commerce are applied by each of the members of the union to the trade of territories not included in the union”. It is – at first sight - surprising to see then that the EU and Turkey negotiate and sign FTAs separately, while being bound by a customs union at the same time. This is the puzzle which is addressed in this short article. We illustrate the actual divergence in FTA policies, show the reasons behind it, and point to the sub-optimality of the current arrangement. We also show the relevance of this case for the post-Brexit EU-UK trade relations.

title: Essays in empirical and behavioral asset pricing
Creators: name: Young, Trevor
Publisher: name: London Business School
Year: 2021

description: This thesis presents three essays. The first chapter examines the information content of aggregate mutual fund alpha. Recent evidence shows that mutual funds collectively buy overvalued stocks. I hypothesize that aggregate alpha arises in part from such stocks becoming even more overvalued, and thus is a measure of market overvaluation. A one-standard-deviation increase in aggregate alpha corresponds to a 0.83 percentage point decrease in the following month's excess market return, and aggregate alpha yields a monthly out-of-sample R2 of 3.64%. Moreover, higher aggregate alpha predicts higher anomaly returns and lower aggregate earnings surprises. The market-return predictability stems from funds with high investment in overvalued stocks, and from small-cap or growth investment styles. The evidence is difficult to reconcile with rational explanations based on benchmarking, flow, or catering. The second chapter, joint with Justin Birru, tests a straightforward time-series prediction of sentiment; sentiment should exhibit its strongest effects on asset prices at times when valuations are most subjective. Consistent with this, we show that a one-standard-deviation increase in aggregate uncertainty amplifies the predictive ability of sentiment for market returns by two to four times relative to when uncertainty is at its mean. For the cross-section of returns, the predictive ability of sentiment for test assets expected to be most sensitive to sentiment and for anomalies is substantially larger in times of higher uncertainty. The final chapter, joint with Justin Birru and Hannes Mohrschladt, provides a unifying explanation for a number of existing risk puzzles. Systematic mispricing primarily affects speculative stocks and tends to take the form of overpricing, predicting lower average returns. Because speculative stocks are typically deemed risky by rational models, failing to control for exposure to systematic mispricing can bias tests of risk-return tradeoffs. Controlling for the effects of systematic mispricing, we recover robust positive risk-return relations for a large number of cross-sectional risk proxies, including many low-risk, distress, and illiquidity anomalies.

Inference at Scale Significance Testing for Large Search and Recommendation Experiments

description: A number of information retrieval studies have been done to assess which statistical techniques are appropriate for comparing systems. However, these studies are focused on TREC-style experiments, which typically have fewer than 100 topics. There is no similar line of work for large search and recommendation experiments; such studies typically have thousands of topics or users and much sparser relevance judgements, so it is not clear if recommendations for analyzing traditional TREC experiments apply to these settings. In this paper, we empirically study the behavior of significance tests with large search and recommendation evaluation data. Our results show that the Wilcoxon and Sign tests show significantly higher Type-1 error rates for large sample sizes than the bootstrap, randomization and t-tests, which were more consistent with the expected error rate. While the statistical tests displayed differences in their power for smaller sample sizes, they showed no difference in their power for large sample sizes. We recommend the sign and Wilcoxon tests should not be used to analyze large scale evaluation results. Our result demonstrate that with Top-N recommendation and large search evaluation data, most tests would have a 100% chance of finding statistically significant results. Therefore, the effect size should be used to determine practical or scientific significance.

In particular, we show that the pinned commuting and pinned stoquastic Local Hamiltonian problems are quantum-Merlin-Arthur–complete. Second, we investigate pinned dynamics and demonstrate that fixing a single qubit via often repeated measurements results in universal quantum computation with commuting Hamiltonians. Finally, we discuss variants of the ground-state connectivity (GSCON) problem in light of pinning, and show that stoquastic GSCON is quantum-classical Merlin-Arthur–complete.

description: SASyLF was released in 2008 and used as a proof assistant in courses at several universities. It proved itself useful and has continued to be used, and each iteration of use has encouraged further development: fixing bugs and adding enhancements. This paper describes how SASyLF was developed while keeping true to its purpose. Most notable are making substitutions explicit, support of "and" and "or," support for mutual and lexicographic induction, and IDE support.

description: Low frequency quasi-periodic oscillations (QPO) with periods between ~10 s and ~0.05 s are often seen in the X-ray flux of accreting stellar-mass black holes. These are often attributed to the Lense-Thirring precession of the inner accretion flow, a General Relativistic effect caused by the spin of the black hole. QPO phase-resolved spectroscopy (measuring how the X-ray spectrum changes with QPO phase) provides the best test of this model against alternative interpretations, since precession leads to a rocking of the ~6.4 keV iron fluorescence line between Doppler red and blue shift over the course of each QPO cycle. I will present the results of our QPO phase-resolved spectral analysis of the bright black hole X-ray binary system GRS1915+105 for which we utilise simultaneous data from NICER and NuSTAR. We constrain the iron line profile to change systematically with QPO phase and are able to attribute this to asymmetric illumination of the accretion disc with >2 sigma statistical significance, along with a changing reflection fraction with >3 sigma statistical significance. This constitutes the best evidence to date that the QPO is a geometric effect, driven by a non-axi-symmetric process, consistent with precession.

description: The 2018 California Current Ecosystem Survey (CCES) was a multidisciplinary survey of the marine ecosystem from southern British Columbia, Canada to northern Baja California, Mexico. CCES 2018 was conducted from 26 June to 4 December 2018 aboard the NOAA ship Reuben Lasker. In this report we present the preliminary results of the passive acoustic monitoring efforts using DASBRs. DASBRs were first used in a broad-scale Passive Acoustics Survey of Cetacean Abundance Levels (PASCAL) in the California Current during 2016, (Keating et al., 2018). Acoustic recordings were analyzed to detect echolocation signals from beaked whales, sperm whales (Physeter macrocephalus), and dwarf and pygmy sperm whales (Kogia spp.). In 2016, the most common beaked whale echolocation pulses were from Cuvier’s beaked whale (Ziphius cavirostris), Baird’s beaked whale (Berardius bairdii), Stejneger’s beaked whale (Mesoplodon stejnegeri), and two unidentified species of beaked whales whose echolocation pulses were referred to as BW43 and BW39V. Here we present analyses of the DASBR deployments from the CCES 2018 project.
