Essays on macroeconomics
Creators: name: Zhang, Dongxiao
Publisher: name: University of British Columbia
Year: 2022

description: This thesis consists of three chapters that study various aspects of the interaction between macroeconomics, family economics, and labor economics, with a primary focus on the economic linkage between parents and children. Chapter 2 presents a theoretical study contributing to the literature on intergenerational occupational persistence. I develop an occupational choice model characterized by information friction and intergenerational transmission of ability to analyze the relationship between parents' and children's occupational choices and the consequence on workers' earnings over their lifetimes. In this model, workers enter the labor market with imperfect information about their innate abilities, learn their abilities from working, and optimize their occupational choices. The model is calibrated to a unique employer--employee-matched data source from Germany to match observed empirical moments and investigate how the information friction could improve the occupation-talent allocation in the labor force through a counterfactual experiment. In Chapter 3, I document a set of novel empirical facts characterizing occupational persistence across generations by using both survey and administrative-level panel data from Germany. The pattern of intergenerational occupational persistence against occupations' wage-premia ranking is identified as U-shaped: a worker is more likely to work in the same occupation as their father if their father's occupation is associated with a high or low wage premium. This U-shaped pattern can be consistently explained by the theory discussed in Chapter 2. The information friction regarding ability plays a critical role in delaying workers' learning processes and leads to occupation-talent mismatches, especially when workers are in their early career stages. Chapter 4 investigates how the one-child policy affects household-level saving and spending behaviors as well as aggregate-level savings and human capital accumulation in China. To answer this question, I propose a life-cycle model with intergenerational transfers and human capital accumulation. This life-cycle model provides channels to understand households' responses to fertility restrictions and the corresponding impact on savings and investments in per-child education. The present theory also provides a feasible approach based on demographic composition changes to understand the linkage between the household-level dynamics and the evolution of savings and human capital accumulation at the aggregate level.

description: The single-site dynamical mean-field approximation is used to solve a model of high-Tc cuprate superconductors which includes both d_{x^2-y^2} and d_{3z^2-r^2} orbitals on the Cu as well as the relevant oxygen states. Both T (with apical oxygen) and T' (without apical oxygen) crystal structures are considered. In both phases, inclusion of the d_{3z^2-r^2} orbital is found to broaden the range of stability of the charge transfer insulating phase. For equal charge transfer energies and interaction strengths, the T' phase is found to be less strongly correlated than the T phase. For both structures, d-d excitons are found within the charge-transfer gap. However, for all physically relevant dopings the Fermi surface is found to have only one sheet and the admixture of d_{3z^2-r^2} into ground state wave function remains negligible (<5%). Inclusion of the extra orbitals is found not to resolve the discrepancy between computed and observed conductivity in the insulating state.

title: Photography and narrative : An investigation of serial imagery
Creators: name: Halliwell, K
Publisher: name: University of Kent
Year: 2022

description: The history of photographic serial imagery cannot be taken in isolation. It shares many features with various ancient and medieval visual serial texts and later painted series. Nor can the conditions for its creation be divorced from the theatre, the magic lantern and film. From its inception photography exploited serial texts, mainly in reportage, advertising, the photoroman, and art practice. There are various problems in the characterisation of narrative. An examination of traditional problematic areas shows that 'visual narrative' depends ultimately on the signification of a state change through the use of a transformational matrix. Narrative, however, works on three levels. The 'text' can be defined according to the traditional features of visual signs which motivate the imaginative construction of the object through the image. Serial narrative texts also require basic signifying conditions which establish relevant differentiations and cohesions, for which the interstice is to be considered as the point of narrative montage. The narrative work also involves organisational features on the level of 'discourse'. Following a Genettian analysis of discourse and story relations indicates where the static visual narrative's strengths and weaknesses lie and where the analysis needs to be extended or reduced. This applies to temporal relations as well as focalisation and modality. The incorporation of the verbal text also needs to be considered. The accompanying verbal can be formally divided into title or text, but functionally it will depend on the strengths and weaknesses of the visual's textual and discursive capabilities. Text and image can only be seen in symbiotic relation. Ultimately, however, a consideration of the role of the reader and the sign as read is vital. One would have to consider other pragmatic and ideological factors which are involved in this activity.
Complex asteroseismology of the hybrid B-type pulsator $γ$ Pegasi: a test of stellar opacities

description: Using the updated oscillation spectrum of $γ$ Pegasi, we construct a set of seismic models which reproduce two pulsational frequencies corresponding to the $\ell=0$, p$_1$ and $\ell=1$, g$_1$ modes. Then, we single out models which reproduce other well identified modes. Finally, we extend our seismic modelling by a requirement of fitting also values of the complex, nonadiabatic parameter $f$ associated to each mode frequency. Such complex asteroseismology of the B-type pulsators provides a unique test of stellar metallicity and opacities. In contrast to our previous studies, results for $γ$ Peg indicate that both opacity tables, OPAL and OP, are equally preferred.

description: By fitting the frequencies of simultaneous lower and upper kilohertz Quasi-Periodic Oscillations (kHz QPOs) in two prototype neutron star QPO sources (4U~1636-536 and Sco X-1), we test the predictive power of all currently proposed QPO models. Models predict either a linear, power-law or any other relationship between the two frequencies. We found that for plausible neutron star parameters (mass and angular momentum), no model can satisfactorily reproduce the data, leading to very large chi-squared values in our fittings. Both for 4U~1636-53 and Sco X-1, this is largely due to the fact that the data significantly differ from a linear relationship. Some models perform relatively better but still have their own problems. Such a detailed comparison of data with models shall enable to identify routes for improving those models further.

Techniques in learning-based approaches for character animation
Creators: name: Ling, Hung Yu
Publisher: name: University of British Columbia
Year: 2022

description: Contemporary computer animation research has benefited substantially from the advancement of deep learning and deep reinforcement learning methods in the past decade. Despite the performance and flexibility of learning-based methods, significant manual effort is still required to tune the training data, algorithms, and environments, especially when computing resources are limited. In this thesis, we develop and evaluate a variety of learning-based methods that enable new skills, and that improve the stability of the learning algorithms and the quality of the synthesized motions. First, we present a framework for learning autoregressive kinematic motion generators and controllers from motion capture data. By disentangling the motion modelling and control tasks, our framework can efficiently synthesize controllable virtual characters by leveraging the strengths of supervised and reinforcement learning. Second, we study the effects of symmetry in learning physics-based locomotion controllers for bipedal characters. We evaluate four possible methods to impose symmetry and show that enforcing symmetry improves the naturalness and task performance of the trained controllers. Third, we explore the role of learning curricula in solving challenging physics-based stepping-stone tasks. The learning is significantly more robust and efficient under a learning curriculum which gradually increases the task difficulty. Finally, we combine simplified models and imitation learning to train brachiation controllers. We show that sparse task objective alone is sufficient for training a controller in an abstracted point-mass brachiation environment. Then, using the point-mass as a reference trajectory for the centre-of-mass, we can learn a control policy for a physics-based 14-link planar articulated gibbon model.

 Remarks. After examining the images of the holotype of P. japonicus Ashmead available on the USNM website, I conclude that the species belongs to the family Perilampidae, genus Chrysolampus Spinola. This is confirmed by Z. Bouček’s identification label from 1989. Thus, the following combination is proposed: Chrysolampus japonicus (Ashmead, 1904), comb. nov.

description: We deploy algebraic complexity theoretic techniques for constructing symmetric determinantal representations of for00504925mulas and weakly skew circuits. Our representations produce matrices of much smaller dimensions than those given in the convex geometry literature when applied to polynomials having a concise representation (as a sum of monomials, or more generally as an arithmetic formula or a weakly skew circuit). These representations are valid in any field of characteristic different from 2. In characteristic 2 we are led to an almost complete solution to a question of Bürgisser on the VNP-completeness of the partial permanent. In particular, we show that the partial permanent cannot be VNP-complete in a finite field of characteristic 2 unless the polynomial hierarchy collapses.

Understanding the social licence to use animals for scientific purposes and the role of institutional transparency
Creators: name: Brunt, Michael Warren
Publisher: name: University of British Columbia
Year: 2022

description: Meaningful societal dialogue about the use of animals for scientific purposes requires a level of transparency regarding the procedures these animals are likely to experience and the processes institutions engaged in using animals employ to determine what is acceptable. The overall thesis objective was to better understand social licence to use animals for scientific purposes and the role of institutional transparency in this process. Analysis of interviews with research animal facility managers and attending veterinarians at Canadian universities showed the interpretation of institutional transparency varied within and between universities, institutional transparency could be influenced by internal and external pressures, and the main barrier to increased transparency was a lack of motivation to change. Transparency was conceptualized in four ways: 1) true transparency; communication of information for the sake of openness, 2) misguided transparency; attempt to educate people about animal research because then they will support it, 3) manipulative transparency; selective release of positive stories to direct public opinion, and 4) fearful non-transparency; not communicating any information for fear of negative opposition to animal research. Given the diverse understanding of the purpose of transparency, I suggest that active and sustained communication between senior administrators, university veterinarians, animal care staff, and scientists is necessary to build a consensus on how to pursue transparency. While generating consensus at the local institutional level is important, substantial progress would likely benefit from involvement of all stakeholders to work collaboratively and agree to a shared vision for transparency. Analysis of a mix-methods survey that requested public input on proposed animal experiments found that many participants provided substantive and nuanced input that could aid in institutional decision making including social policy alternatives. Analysis of a second mix-methods survey found the public expected oversight for invertebrate animals used for scientific experiments and the absence of this oversight decreased public confidence and trust in scientists. In summary, my results suggest that increased information in the public domain about these practices, incorporation of societal values into decision making, and increased opportunities for participation in research animal governance could help institutions maintain social licence for these practices.

description: Using density functional theory we investigate the evolution of the magnetic ground state of NbFe$_{2}$ due to doping by Nb-excess and Fe-excess. We find that non-rigid-band effects, due to the contribution of Fe-\textit{d} states to the density of states at the Fermi level are crucial to the evolution of the magnetic phase diagram. Furthermore, the influence of disorder is important to the development of ferromagnetism upon Nb doping. These findings give a framework in which to understand the evolution of the magnetic ground state in the temperature-doping phase diagram. We investigate the magnetic instabilities in NbFe$_{2}$. We find that explicit calculation of the Lindhard function, $χ_{0}(\mathbf{q})$, indicates that the primary instability is to finite $\mathbf{q}$ antiferromagnetism driven by Fermi surface nesting. Total energy calculations indicate that $\mathbf{q}=0$ antiferromagnetism is the ground state. We discuss the influence of competing $\mathbf{q}=0$ and finite $\mathbf{q}$ instabilities on the presence of the non-Fermi liquid behavior in this material.

(Figs 72–120)
 Teasienna Heydon, 2004: 183 –184; type species: T. eirene Heydon, 2004, by original designation and monotypy.
 Diagnosis. Female clava asymmetric due to large area of microsetation (100%) (Figs 75, 87, 95, 120); male clava symmetric (100%) (Figs 74, 106); propodeum with flange-like projections anteriorly partially concealing dorsellum, with median area smooth, and without plicae (100%) (Figs 80, 98, 109, 118); lateral side of prothorax with visible whitish membranous area between posteroventral corner of pronotum and fore coxa, posteroventral corner of pronotum short, rounded (100%) (Figs 79, 89, 108, 117); posterior margin of gena not carinate (100%); medial ventral margin of scape at least partly carinate (100%) (Figs 75, 87, 113); antenna inserted below middle of face (100%) (Figs 75, 84, 93, 103, 113); both mandibles with 3 teeth, inner mandibular tooth double (100%) (Fig. 103); posterior part of mesoscutellum conspicuously surpassing base of propodeum, with one median spine (100%) (Figs 78, 96, 107, 116); marginal vein much shorter than stigmal vein (100%) (Figs 81, 90, 99, 110,119); notauli complete (100%) (Figs 78, 88, 96, 107, 116). Male: scape without any ventral protuberance (100%) (Figs 74, 106).
 Remarks. Due to its very short marginal vein (Figs 81, 90, 99, 110, 119), Teasienna resembles certain Eutrichosomatinae such as Manineura Bouček and Collessina Bouček, but differs from both genera mostly in having the axillae not advanced, and by a different shape of the clypeus and antenna. For differences between Teasienna and Austroterobia, see comments under the latter genus. Previously known only from one Oriental species, the distribution of the genus now extends to the Afrotropical region, where the species diversity seems much higher. The biology is unknown, but given the gastral structure, which is similar to that of Austroterobia, it is highly possible that the hosts are also scale insects.

In this paper we introduce a central extension $Δ$ of AW, obtained from AW by reinterpreting certain parameters as central elements in the algebra. We call $Δ$ the {\it universal Askey-Wilson algebra}. We give a faithful action of the modular group ${\rm {PSL}}_2({\mathbb Z})$ on $Δ$ as a group of automorphisms. We give a linear basis for $Δ$. We describe the center of $Δ$ and the 2-sided ideal $Δ[Δ,Δ]Δ$. We discuss how $Δ$ is related to the $q$-Onsager algebra.

description: Quantum theory is usually formulated in terms of abstract mathematical postulates, involving Hilbert spaces, state vectors, and unitary operators. In this work, we show that the full formalism of quantum theory can instead be derived from five simple physical requirements, based on elementary assumptions about preparation, transformations and measurements. This is more similar to the usual formulation of special relativity, where two simple physical requirements -- the principles of relativity and light speed invariance -- are used to derive the mathematical structure of Minkowski space-time. Our derivation provides insights into the physical origin of the structure of quantum state spaces (including a group-theoretic explanation of the Bloch ball and its three-dimensionality), and it suggests several natural possibilities to construct consistent modifications of quantum theory.

description: We consider the problem of bandwidth selection by cross-validation from a sequential point of view in a nonparametric regression model. Having in mind that in applications one often aims at estimation, prediction and change detection simultaneously, we investigate that approach for sequential kernel smoothers in order to base these tasks on a single statistic. We provide uniform weak laws of large numbers and weak consistency results for the cross-validated bandwidth. Extensions to weakly dependent error terms are discussed as well. The errors may be α-mixing or L2-near epoch dependent, which guarantees that the uniform convergence of the cross validation sum and the consistency of the cross-validated bandwidth hold true for a large class of time series. The method is illustrated by analyzing photovoltaic data.

Monolithically integrated 940 nm AlₓGa1-ₓAs distributed Bragg reflectors on bulk Si and Ge substrates
Creators: name: Guo, Jia
Publisher: name: University of British Columbia
Year: 2022

description: To address the dramatically increased market demand for vertical-cavity surface-emitting lasers (VCSELs) as light sources in distance and three-dimensional (3D) sensing for consumer and industry products, monolithic integration of VCSELs on bulk Si and Ge substrates was investigated in this work. It has the benefits of much larger wafer size and thus higher throughput, lower manufacturing cost, and the compatibility to integrate with silicon complementary metal-oxide-semiconductor (CMOS) field-effect transistors. Distributed Bragg reflectors (DBRs), the first and fundamental part of VCSELs, were grown on three engineered bulk Si and Ge substrates: GaInAs/Ge substrate, graded-GaAsP/Si substrate, and aspect ratio trapping (ART)-Ge/Si substrate. A conventional bulk GaAs wafer was used as the control sample. Material characterization and optical performance measurement were performed on the fabricated DBRs. The GaInAs/Ge DBRs have comparable surface conditions and optical performance to the conventional bulk GaAs DBRs in terms of surface topology, thickness uniformity, and reflectance spectrum, qualifying GaInAs/Ge substrates for full VCSEL fabrication. The GaAsP/Si DBRs have defected surfaces with a relatively high density of surface bumps and a cross-hatch pattern. Moreover, the GaAsP/Si DBRs have irregular double-peak-shaped reflectance stopbands. The ART-Ge/Si DBRs have the worst surface quality, making them unsuitable for further VCSEL development. A surface scratch test was proposed and conducted to study the impact of the surface cross-hatch pattern on the DBR reflectance spectrum. A similar double-peak-shaped stopband was reproduced by manually introducing cross scratches on the high-quality bulk GaAs DBR surface. It strongly suggests that the cross-hatch pattern on the GaAsP/Si DBR surface is the root cause of the irregular double-peak-shaped stopband. A surface chemical mechanical polishing (CMP) was introduced as a potential solution to flatten the cross-hatch pattern and improve the reflectance spectrum. Data suggests the improvement of the double-peak-shaped stopband by reducing the surface roughness. However, the CMP process was with high variation and introduced new random scratches that affect the overall reflectance. Further epitaxy development and surface improvement are suggested to improve the bulk Si-based DBR performance.
Ping-pong Asylum: Renegotiating the Safe Third Country Agreement
Creators: name: Falconer, Robert

description: From January 2017 to February 2019, approximately 42,000 asylum seekers have been intercepted by the RCMP while crossing the Canada-U.S. border. Asylum seekers intercepted by the RCMP represented just over one third of all asylum claims over this period. Another 70,800 other asylum seekers claimed protection at a Canadian port of entry upon arrival, or at inland office after having resided in Canada with a form of temporary work, study, or visitor status. By contrast, since January 2017, a little more than 607,500 permanent residents arrived in Canada through legal economic, family, and humanitarian channels.

Recent polling suggests that border security is the most salient immigration issue among the Canadian public.4 Despite these perceptions, border crossers represent only a fraction of the total asylum claim backlog, an inventory of pending cases of people seeking protection in Canada on the basis of fear of persecution in their home country. In February 2019, 4,170 new asylum claims were registered, of which 808 individuals were intercepted at the Canada-U.S. border, making those border claims less than 20% of the total in that month.5 In August 2018, during summer months when border crossings tend to be higher, 4,965 new claims were registered, while the RCMP intercepted 1,747 asylum seekers crossing the border (35% of all

claims in August 2018). The comparison of border crossings versus all claims by month is shown later in this report in Figure 5.

One proposal currently being explored by the Canadian government to reduce crossings, is to renegotiate the “Safe Third Country Agreement” (STCA) with the United States. This policy brief outlines possible benefits and drawbacks of renegotiating the STCA. It begins with describing the current backdrop to renegotiation of the Agreement, including the rise and fall of border crossings, as well as how the STCA works in practice. It then describes reasons to why a renegotiated STCA may stem increases to the asylum claim backlog, while also outlining other potential impacts and downsides to a modified Agreement. It concludes by proposing alternative solutions to renegotiating the STCA that do not carry the same potential downsides.

description: Narrow-Line Seyfert 1 (NLS1) galaxies show extreme properties with respect to the other Seyfert galaxies. Indeed, they are thought to be accreting at Eddington rates and to possess low mass black holes. Therefore, they may represent a key class of objects for understanding the co-evolution of black holes and their host galaxies. We propose that NLS1s represent a class of AGN in which the black hole growth is, and has always been, dominated by secular evolution. Firstly, by looking at the NLS1 host galaxy properties in the literature, we show that the evolution of NLS1s is presently driven by secular processes, much more so than for Broad-Line Seyfert 1s (BLS1s). Secondly, we study the bulges of NLS1 and BLS1 galaxies. Our results demonstrate that NLS1 host bulges are pseudo-bulges and are statistically different from BLS1 bulges. This difference points to the particular importance of secular processes in the past evolution of their hosts. We build on this result to understand the implications on their evolution and the duration of their duty cycle. We show that NLS1s are not necessarily in a special phase of black hole growth and that several Gyr are required for their black hole masses to become similar to BLS1s. Finally, in the light of our results, we discuss the location of NLS1 galaxies on the MBH-σplane and speculate about the connection between the NLS1 galaxy properties and their black hole spin.

description: We introduce a new method that allows one to obtain an analytical cross section for the laser-assisted electron-ion collision in a closed form. As an example we perform a calculation for the hydrogen laser-assisted recombination. The $S$-matrix element for the process is constructed from an exact electron Coulomb-Volkov wave function and an approximate laser modified hydrogen state. An explicit expression for the field-enhancement coefficient of the process is expressed in terms of the dimensionless parameter $κ= |{eε_{0}}/{qω_{0}}|^{2}$, where $e$ and $q$ are the electron charge and momentum respectively, and $ε_{0}$ and $ω_{0}$ are the amplitude and frequency of the laser field respectively. The simplified version of the cross section of the process is derived and analyzed within a soft photon approximation.

description: Two and a half years prior to China's M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan. This article shows that static surface loading in the Zipingpu water reservoir induced Coulomb failure stresses on the nearby Beichuan thrust fault system at <17km depth. Triggering stresses exceeded levels of daily lunar and solar tides and perturbed a fault area measuring 416+/-96km^2. These stress perturbations, in turn, likely advanced the clock of the mainshock and directed the initial rupture propagation upward towards the reservoir on the "Coulomb-like" Beichuan fault with rate-and-state dependent frictional behavior. Static triggering perturbations produced up to 60 years (0.6%) of equivalent tectonic loading, and show strong correlations to the coseismic slip. Moreover, correlations between clock advancement and coseismic slip, observed during the mainshock beneath the reservoir, are strongest for a longer seismic cycle (10kyr) of M>7 earthquakes. Finally, the daily event rate of the micro-seismicity (M>0.5) correlates well with the static stress perturbations, indicating destabilization.

description: The ratio of the cross section for $p\bar{p}$ interactions producing a $Z$ boson and at least one $b$ quark jet to the inclusive $Z+{\rm jet}$ cross section is measured using $4.2\ {\rm fb}^{-1}$ of $p\bar{p}$ collisions collected with the \dzero\ detector at the Fermilab Tevatron collider at $\sqrt{s}=1.96$ TeV. The $Z\rightarrow\ell^+\ell^-$ candidate events with at least one $b$ jet are discriminated from $Z+$ charm and light jet(s) events by a novel technique that exploits the properties of the tracks associated to the jet. The measured ratio is $0.0193\pm0.0027$ for events having a jet with transverse momentum $\pt > 20 \GeV$ and pseudorapidity $|η| \leq 2.5$, which is the most precise to date and is consistent with theoretical predictions.

Machine learning for diagnosing functional heart disease in echocardiography
Creators: name: Behnami, Delaram
Publisher: name: University of British Columbia
Year: 2022

description: Heart failure (HF) is associated with poor patient outcomes and burdens healthcare systems and clinicians. Fortunately, therapeutic options are available for managing cardiac dysfunction if diagnosed early. Echocardiography (echo) can be used to assess cardiac function swiftly and detect signs or risk factors of HF. Nonetheless, echo acquisition and interpretation require extensive training and experience, leading to exceeding demand for the available clinical echo services. This thesis investigates the feasibility of machine learning (ML)-based solutions for analyzing heart function based on clinical echo data and available annotations. The goal is to automate measurements of indicators of functional diseases. We focus on guideline-aware supervised learning frameworks for assessing LV ejection fraction (EF), regional wall motion abnormality (WMA), and LV diastolic dysfunction (LVDD). We propose spatio-temporal neural networks to determine EF from echo cine loops. We utilize multi-task learning with observer variability modelling is leverage the label noise and decouple errors in different available EF labels. In the context of regional systolic function, we present an error quantification and visualization framework to evaluate the generalizability of disease-agnostic models on diseased cohorts. We validate segmentation models trained on standard populations in a WMA cohort and report global and local error metrics with weak wall segment labels. This framework enables us to further identify failure modes in trained ML models. Using the errors obtained from the weak labels, we observed that segmentation performance might become jeopardized in the presence of akinetic LV wall segments. Finally, in the most extensive study of its kind, we demonstrate the impacts of the updated clinical guidelines for diastolic function assessment based on measurements derived from echo. We propose a neural network to replicate the latest clinical guidelines for diastolic function classification and extend this model to a regression framework to obtain a novel continuous LVDD scoring system. Increasing the size and diversity of the training and test set for model training and clinical validation is critical to further developing ML-driven heart disease diagnostic tools. Future work may involve ML-based multi-chamber quantification, myocardium localization, and Doppler image analysis toward automatic disease diagnosis.
