description: The α-formalism is a common way to parametrize the common envelope interaction between a giant star and a more compact companion. The α parameter describes the fraction of orbital energy released by the companion that is available to eject the giant star's envelope. By using new, detailed stellar evolutionary calculations we derive a user-friendly prescription for the λ parameter and an improved approximation for the envelope binding energy, thus revising the α equation. We then determine α both from simulations and observations in a self consistent manner. By using our own stellar structure models as well as population considerations to reconstruct the primary's parameters at the time of the common envelope interaction, we gain a deeper understanding of the uncertainties. We find that systems with very low values of q (the ratio of the companion's mass to the mass of the primary at the time of the common envelope interaction) have higher values of α. A fit to the data suggests that lower mass companions are left at comparable or larger orbital separations to more massive companions. We conjecture that lower mass companions take longer than a stellar dynamical time to spiral in to the giant's core, and that this is key to allowing the giant to use its own thermal energy to help unbind its envelope. As a result, although systems with light companions might not have enough orbital energy to unbind the common envelope, they might stimulate a stellar reaction that results in the common envelope ejection.

description: The multi-fold original paper, in its spacetime reconstruction phase, attributes spacetime to the locations concretized by the random walks, and creation, of (massless) particles, resulting into a discrete, (multi-)fractal spacetime that is non-commutative and yet Lorentz symmetric. The fractal or multi-fractal was inferred from the random walks, but it was actually the only part not explicitly derived. Multi-fold universe are expected to probably have a Cantor-like 𝐸-infinity fractal spacetime.
In this paper, we resume these discussions, but now, we provide microscopic interpretations for spatial and temporal, and so spacetime, (multi-) fractal properties of the multi-fold universe, and their observability, only within a range of cosmological scales, as observed in our real universe. We also relate discreteness of spacetime to the complex scalar field of the Higgs boson, and encounter further corroboration of the fundamental role of the massless Higgs boson.
Fractal state space plays a role in interpreting experiments about the Bell theorem, and related hidden variables. The paper discusses two models, which do not imply that the result of Bell experiments would forbid local hidden variables. The Bell Theorem, and handling of EPR entanglements, was the motivation for proposing the multi-fold mechanisms, which implement non-locality with local Physics. Interestingly, with discrete spacetime, the multi-fold W-type hypothesis, massless Higgs boson random walks, and fractal properties, multi-fold universes can support all these models: local physics and hidden variables seem to be reconcilable with the Bell experiments, as was the original intent for the multi-fold theory. And there is no need to give in to super determinism, retro-causality, or to lose free will.

How do citizens develop perceptions of job competition from immigrants? : economic interests and immigration attitudes in Canada
Creators: name: Straughan, Robert William
Publisher: name: University of British Columbia
Year: 2022

description: The incumbent Liberal Party of Canada (LPC) has set ambitious targets for the number of immigrants to be granted permanent residency annually. At the same time, there are no other major Canadian political parties with anti-immigration platforms. Despite this elite consensus on the necessity of economic immigration, the opinions of ordinary Canadian citizens toward immigrants, and in particular, whether Canadians view immigrants as potential competitors for jobs, have not been fully understood. Drawing upon a representative web-based survey in Canada conducted by Professors Matthew Wright from the University of British Columbia and Morris Levy from the University of Southern California in March 2022, this thesis addresses this problem: How do economic interests influence the immigration attitudes of ordinary Canadian citizens? The results suggest that respondents’ perceived economic context shapes their sociotropic job threat from immigration, but not their personal job threat from immigration. In addition, both personal and sociotropic job threat from immigration are influenced by political partisanship, with a stark difference between Liberal and Conservative supporters. Finally, my findings demonstrate that both personal and sociotropic job threat from immigration are associated with Canadians’ preferred level of immigration to Canada. Overall, this thesis validates the role of economic interests in the formation of immigration opinions, and reveals how these economic interests change based on information received by citizens. Economic self-interest, which scholars criticize as irrelevant to immigration attitudes, remains important in shaping public opinion on immigration.
Emotional Engagement among Anxious Language Learners from the Perspective of Flow: An Exploratory Study in a University Classroom in Saudi Arabia
Creators: name: Almukhaild, Haydab A.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: A growing body of evidence suggests that engagement is closely linked to learners’ enjoyment and focus on the task at hand, thereby facilitating second language (L2) development. However, the topic of learner engagement has received scant attention in the L2 field. Facilitating the advancement of knowledge about the emotional dimension of engagement, the research presented in this thesis aims to explore engagement from the perspective of flow among learners with speaking-related anxiety in an English as a Foreign Language (EFL) classroom in Saudi Arabia. The study utilised a mixed methods approach with a qualitative focus. Data were collected in two phases. In the preliminary phase of the study, which addressed questions related to the underlying mechanisms of speaking-related anxiety, the Foreign Language Classroom Anxiety Scale was used to assess learners’ levels of anxiety, followed by conducting classroom observations (11 hours), and semi-structured interviews (n = 30) with students who demonstrated moderate to high levels of anxiety. The second, main phase addressed the practical applicability of flow theory’s principles and assessed the impact of five carefully adapted speaking communicative tasks that meet selected flow principles on anxious learners’ emotional engagement experiences. These speaking tasks were implemented online to a class of 30 students over a period of eight weeks with the aim of reducing anxiety and increasing engagement. Data from the intervention phase were collected using weekly open-response questionnaires (n = 127), stimulated recall interviews (n = 25) and a series of semi-structured interviews with the course teacher (n = 3). The results showed that anxious learners can move towards increased levels of emotional engagement, and in some instances, flow. The findings indicated that task features work together and interact with multiple social contextual factors to produce emotionally engaging task experiences. In light of these encouraging conclusions, implications were proposed, and suggestions were identified for future research.
The quantum hall effect and bulk-edge correspondence on lattice systems
Creators: name: Furlotte, Justin
Publisher: name: University of British Columbia
Year: 2022

description: In this thesis, we investigate the integer quantum Hall effect (IQHE). Discovered in 1980 by Nobel laureate Klaus von Klitzing, the IQHE is a phenomenon in which the conductivity of a 2-dimensional electron gas is quantized in exact integer multiples of q²/h when subjected to a strong magnetic field at very low temperatures. In particular, we provide a rigorous theoretical description of a phenomenon known as bulk-edge correspondence, wherein the value of the Hall conductivity is unaffected by whether or not one considers a system with an edge or a bulk (i.e. edgeless) system. This is accomplished in two settings. First, we ignore interactions between electrons, and then proceed to the more challenging interacting setting.

description: In this paper, we start from an extension of the notion of holonomy on diffeological bundles, reformulate the notion of regular Lie group or Frölicher Lie groups, state an Ambrose-Singer theorem that enlarges the one stated in \cite{Ma2}, and conclude with a differential geometric treatment of KP hierarchy. The examples of Lie groups that are studied are principally those obtained by enlarging some graded Frölicher (Lie) algebras such as formal $q-$series of the quantum algebra of pseudo-differential operators. These deformations can be defined for classical pseudo-differential operators but they are used here on formal pseudo-differential operators in order to get a differential geometric framework to deal with the KP hierarchy that is known to be completely integrable in the sense of Frobenius. Here, we get an integration of the Zakharov-Shabat connection form by means of smooth sections of a (differential geometric) bundle with structure group some groups of $q-$deformed operators. The integration obtained by Mulase \cite{M1}, and the key tools he developped, are totally recovered on the germs of the smooth maps of our construction. The tool coming from (classical) differential geometry used in this construction is the holonomy group, on which we have an Ambrose-Singer-like theorem: the Lie algebra is spanned by the curvature elements. This result is proved for any connection a diffeological principal bundle with structure group a regular Frölicher Lie group. The case of a (classical) Lie group modelled on a complete locally convex topological vector space is also recovered and the work developped in \cite{Ma,Ma2} is completed.

description: Using Scanning tunneling spectroscopy (STS), we report the correlation between spatial gap inhomogeneity and the zinc (Zn) impurity resonance in single crystals of Bi$_{\mathrm{2}}$Sr$_{\mathrm{2}}$Ca(Cu$_{\mathrm{1-}x}$Zn$_{x}$)$_{\mathrm{2}}$O$_{\mathrm{8+}δ}$ with different carrier (hole) concentrations ($p$) at a fixed Zn concentration ($x$ $\sim$ 0.5 % per Cu atom). In all the samples, the impurity resonance lies only in the region where the gap value is less than $\sim$ 60 meV. Also the number of Zn resonance sites drastically decreases with decreasing $p$, in spite of the fixed $x$. These experimental results lead us to a conclusion that the Zn impurity resonance does not appear in the large gap region although the Zn impurity evidently resides in this region.

description: We consider the most general three point function for gravitational waves produced during a period of exactly de Sitter expansion. The de Sitter isometries constrain the possible shapes to only three: two preserving parity and one violating parity. These isometries imply that these correlation functions should be conformal invariant. One of the shapes is produced by the ordinary gravity action. The other shape is produced by a higher derivative correction and could be as large as the gravity contribution. The parity violating shape does not contribute to the bispectrum [1106.3228, 1108.0175], even though it is present in the wavefunction. We also introduce a spinor helicity formalism to describe de Sitter gravitational waves with circular polarization. These results also apply to correlation functions in Anti-de Sitter space. They also describe the general form of stress tensor correlation functions, in momentum space, in a three dimensional conformal field theory. Here all three shapes can arise, including the parity violating one.

description: Scanning tunneling spectroscopies in the subKelvin temperature range were performed on superconducting Silicon epilayers doped with Boron in the atomic percent range. The resulting local differential conductance behaved as expected for a homogeneous superconductor, with an energy gap dispersion below +/- 10%. The spectral shape, the amplitude and temperature dependence of the superconductivity gap follow the BCS model, bringing further support to the hypothesis of a hole pairing mechanism mediated by phonons in the weak coupling limit.

Effects of human activities, environment, and time on eelgrass-associated epifaunal communities
Creators: name: Adamczyk, Emily Mei-Ying
Publisher: name: University of British Columbia
Year: 2022

description: Eelgrass (Zostera marina) is a coastal marine angiosperm found in the Northern Hemisphere and forms expansive meadows in sheltered estuaries and bays, providing habitat for a high diversity of organisms, including algae, invertebrates, microbes, fish, birds, and mammals. It also provides invaluable ecosystem services for humans, including coastal storm protection, carbon sequestration, and nutrient cycling. However, eelgrass meadows are threatened worldwide by numerous anthropogenic activities, including shoreline modification, overfishing, land-based nutrient loading, and climate change. In British Columbia, Canada, eelgrass ecosystems are vulnerable to human activities such as habitat destruction, fishing, and pollution, and warming waters, which can cumulatively lead to negative impacts on eelgrass and associated fauna. To understand how environmental variation and BC-specific human activities affect eelgrass ecosystems temporally and spatially, I used a three-year, monthly observational time series of two trophic groups, statistical modeling, and an experiment to study how eelgrass communities and species interactions vary at the micro and macro scales. I show that eelgrass and epiphytic algae biomass change seasonally, and the timing of their peak biomasses varies interannually and is driven by nutrient availability and mesograzer abundances. I also show that human activities have a negative effect on eelgrass biomass, epiphytic algae, and epifaunal invertebrate abundances and species richness. Lastly, I show the first experimental evidence that eelgrass leaves host a core microbiota, eelgrass leaf-associated microbial communities are primarily driven by their surrounding environment, yet there may be host influence because microbial communities are resistant to environmental change within short periods of time. This research provides new insight to how environmental variability and human activities shape eelgrass-associated epifauna communities. This information can be used to predict how eelgrass ecosystems may change over time, which can help inform management decisions for restoration and conservation practices. Implementing more regulations for coastal anthropogenic activities may help ensure that eelgrass, and the organisms and humans that depend on it, will be sustained well into the future.

description: In this paper, we study the motion of photons around a Kehagias-Sfetsos (KS) black hole and obtain constraints on IR modified Ho$\check{r}$ava gravity without cosmological constant ($\sim Λ_{W}$). An analytic formula for the light deflection angle is obtained. For a propagating photon, the deflection angle $δϕ$ increases with large values of the Ho$\check{r}$ava gravity parameter $ω$. Under the UV limit $ω\longrightarrow \infty$, deflection angle reduces to the result of usual Schwarzschild case, $4GM/R$. It is also found that with increasing scale of astronomical observation system the Ho$\check{r}$ava-Lifshitz gravity should satisfy $|ωM^2|>1.1725 \times10^{-16}$ with 12% precision for Earth system, $|ωM^2| > 8.27649 \times 10^{-17}$ with 17% precision for Jupiter system and $|ωM^2| > 8.27650\times 10^{-15}$ with 0.17% precision for solar system.

Epigenetic Properties of Reproduction and Ageing in Hymenoptera
Creators: name: Brink, Kristiana E.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Epigenetic mechanisms expand the genome’s regulatory flexibility. Whilst these mechanisms are conserved across eukaryotes, insects display high variation in DNA methylation profiles making them an ideal study to infer divergent function and evolution of these mechanisms. This thesis explores the role of DNA methylation and histone modifications in two species of Hymenoptera; the eusocial bumblebee Bombus terrestris and the solitary wasp Nasonia vitripennis. Previous work has demonstrated an association between epigenetic mechanisms and the reproductive plasticity found within social insects. I find, in contrast with previous studies, that chemical alteration to the methylome in B. terrestris workers does not induce reproductive morphology and that discrepancies between studies on the role of DNA methylation is due to greater inter-colony variation in DNA methylation than between castes. I also conduct the first investigation into histone modifications between reproductive castes in B. terrestris and find, like DNA methylation, they vary greatly between colonies. I show through both B. terrestris and N. vitripennis that perturbations to the epigenome via chemical modifiers can be inconsistent and highlight the need to more targeted disruption to untangle the function of these epigenetic markers. Given the confounding effect of the genetic background of colonies, I highlight the use of solitary species such as N. vitripennis to determine the functional role of these mechanisms in insects. Finally, due to the association between DNA methylation and ageing in mammals, I investigate DNA methylation and transcriptomic responses in N. vitripennis with ageing. I find hallmarks of ageing in both the methylome and transcriptome as well as a large sex-bias. Overall, this thesis enhances our understanding of epigenetics in Hymenoptera and sheds light on the need for functional validation of epigenetic modifications to further elucidate their role in regulating gene expression and how this impacts plastic phenotypes such as reproduction and ageing.

description: A functional method to achieve the summation of all Feynman graphs relevant to a particular Field Theory process is suggested, and applied to QED, demonstrating manifestly gauge invariant calculations of the dressed photon propagator in approximations of increas- ing complexity. These lead in a natural way to the extraction of the leading logarithmic divergences of every perturbative order, and to a demonstration of the possible cancellation of all such divergences in the calculation of the (inverse of the) photon's wavefunction renormalization constant Z3. This analysis provides a qualitative understanding of why the measured value of the renormalized fine structure constant is, approximately, 1/137.

description: While humanity has not yet observed any extraterrestrial intelligence (ETI), contact with ETI remains possible. Contact could occur through a broad range of scenarios that have varying consequences for humanity. However, many discussions of this question assume that contact will follow a particular scenario that derives from the hopes and fears of the author. In this paper, we analyze a broad range of contact scenarios in terms of whether contact with ETI would benefit or harm humanity. This type of broad analysis can help us prepare for actual contact with ETI even if the details of contact do not fully resemble any specific scenario.

A theory of extra radiation in the Universe

description: Recent cosmological observations, such as the measurement of the primordial 4He abundance, CMB, and large scale structure, give preference to the existence of extra radiation component, Delta N_nu > 0. The extra radiation may be accounted for by particles which were in thermal equilibrium and decoupled before the big bang nucleosynthesis. Broadly speaking, there are two possibilities: 1) there are about 10 particles which have very weak couplings to the standard model particles and decoupled much before the QCD phase transition; 2) there is one or a few light particles with a reasonably strong coupling to the plasma and it decouples after the QCD phase transition. Focusing on the latter case, we find that a light chiral fermion is a suitable candidate, which evades astrophysical constraints. Interestingly, such a scenario may be confirmed at the LHC. As a concrete example, we show that such a light fermion naturally appears in the E_6-inspired GUT.

Seasonality in the community composition and food web structure of plankton in the Strait of Georgia
Creators: name: McEwan, Nicole
Publisher: name: University of British Columbia
Year: 2022

description: The Strait of Georgia (SoG) is a productive, temperate, and coastal ecosystem in the Northeast Pacific Ocean. Throughout a year in the SoG, plankton productivity and community structure have strong seasonal variations. However, the diverse range of plankton species, trophic processes, and interactions are often over-simplified in food web models. The objectives of this study were to: a) describe the seasonal trends in plankton community composition, biomass, and vertical distribution; b) represent the seasonal food web structure of the plankton community; and c) compare this complex and seasonal modelling approach to a more common and simplified approach. In the spring, diatoms dominate the plankton biomass in the SoG, leading to high primary productivity and fueling zooplankton growth. In summer, primary production is nutrient limited, leading to a decline in diatom biomass and increased mixotrophic flagellate dominance. Zooplankton biomass, dominated by large crustaceans including copepods, amphipods, and euphausiids, peaks and their diets shift to become more omnivorous. In winter, plankton biomass and productivity are low. Based on these seasonal trends, I constructed a food web model for each season (spring, summer, and winter), with the plankton community represented by ten mesozooplankton groups, two mixotrophic microzooplankton groups, one phytoplankton group, one heterotrophic bacteria group, and one detrital group. The spring food web is mostly fueled by high diatom primary production. However, the microbial loop, consisting of detritus, heterotrophic bacteria, and microzooplankton, shifts to become an important energy source for the system under limiting conditions in the summer and winter food webs. These structural changes throughout a year could have important implications and insights for higher trophic levels, such as into the seasonal food availability and quality for plankivorous fish. Finally, I compared this detailed seasonal approach to plankton modelling with an aggregated and year-averaged approach. The microbial loop is often excluded from coastal ecosystem models but is an important component, influencing trophic positions and transfer efficiencies. However, aggregating plankton groups appears to be an adequate approach to ecosystem modelling in the SoG, but modelling decisions should be driven by the research question.
Examining the registration for and unrealized benefits from BC's Fair PharmaCare Plan
Creators: name: Chiu, Candice Man Yee
Publisher: name: University of British Columbia
Year: 2022

description: Background： Fair PharmaCare is a catastrophic public drug plan which is available to all the residents of British Columbia. Coverage is determined by income-based deductibles and therefore requires households to self-register and consent to allowing the Canada Revenue Agency to release their income information to the BC Ministry of Health. In the absence of registration, households are assigned the highest deductible of $10,000. In 2019, the government reduced and eliminated deductibles and family maximum for lower income households. It remains unclear why many households are not registered and whether they could derive additional benefit from registering. Methods： This thesis used administrative data to examine the association between household level, area-based, and needs-based characteristics and time until registration using survival analysis. Interrupted time series analysis was performed to evaluate the impacts of the 2019 policy change on registration rates, as well as the association between registration, drug utilization, and drug expenditures. Simulation methods were used to estimate the unrealized benefits from households not registering. Results： We found a strong association between needs-based factors and registration for Fair PharmaCare. The 2019 policy change that lowered deductibles and coinsurance for lower income households did not result in a change in Fair PharmaCare registration rates, suggesting that there are other factors impacting registration amongst the population not registered for Fair PharmaCare. In the year of registration for Fair PharmaCare, a significant increase in drug expenditures and drug utilization was observed, followed by decreasing drug expenditures and a sustained level of drug utilization over time. If full registration for Fair PharmaCare occurred, we estimated there would be only small changes to private payer savings per household and a very small increase to the PharmaCare budget. Conclusion： Households register for Fair PharmaCare when the need arises, and until the need arises, even if deductibles and coinsurance are lowered, further registration does not appear to occur. The province would not face large expenditures if the full population were to register in Fair PharmaCare. However, the incentive to register amongst those not yet registered is likely small as most households have minimal drug expenditures.

description: In this paper we define distributions on moment spaces corresponding to measures on the real line with an unbounded support. We identify these distributions as limiting distributions of random moment vectors defined on compact moment spaces and as distributions corresponding to random spectral measures associated with the Jacobi, Laguerre and Hermite ensemble from random matrix theory. For random vectors on the unbounded moment spaces we prove a central limit theorem where the centering vectors correspond to the moments of the Marchenko-Pastur distribution and Wigner's semi-circle law.

description: Two measurable characteristics of microwave one-mode photon states are discussed: a rotated quadrature distribution (tomogram) and normally/antinormally ordered moments of photon creation and annihilation operators. Extraction of these characteristics from amplified microwave signal is presented. Relations between the tomogram and the moments are found and can be used as a cross check of experiments. Formalism of the ordered moments is developed. The state purity and generalized uncertainty relations are considered in terms of moments. Unitary and non-unitary time evolution of moments is obtained in the form of linear differential equations in contrast to partial differential equations for quasidistributions. Time evolution is specified for the cases of a harmonic oscillator and a damped harmonic oscillator, which describe noiseless and decoherence processes, respectively.
