An unexpected alliance : a participatory case study of labour-environmentalist collaboration for better transit in the Central Okanagan
Creators: name: Pulles, Kirstin
Publisher: name: University of British Columbia
Year: 2024

description: This thesis investigates the role of Kelowna’s public transit union (the Amalgamated Transit Union Local 1722 – ATU 1722) and a youth-led environmental group (Fridays for Future Kelowna) in the formation of the Okanagan Transit Alliance (OTA). The OTA is a grassroots movement for better public transit in the Central Okanagan. The central research question is, "how can transit unions engage in climate activism?". A participatory activist methodology is employed to study the joint campaign for more accessible, publicly managed, and community-driven transit. The findings are organized into three themes. The first theme is ecosocialism – a political ideology which centers ecological concerns in socialist thought – because the campaign advocates for an ecosocialist goal of ending the private management of Kelowna’s transit. The findings in this area highlight the importance of organizing around people’s basic needs, uncertainty about the role of the government in the campaign, and that engaging in collective struggle is important for developing working-class power. The campaign was co-led by the ATU 1722, and so the second theme, unions, examines their role in the campaign. Under this theme are the findings that the two leading organizations developed a mutually beneficial collaboration, and that the public facing role of bus drivers helped the union build connections with the community. At the same time, contemporary union challenges impacted the ATU 1722’s ability to engage in effective advocacy. Finally, under the third theme of organizing, the research broadly explores organizing tactics to develop the climate justice movement. We found that a welcoming environment and co-creation led to high participation levels, and that relationships were fundamental to the campaign. This thesis highlights the potential of unions to play a pivotal role in climate activism, bridging the gap between labor and environmental concerns. The case of ATU 1722, Fridays for Future Kelowna, and the OTA serves as an inspiring example of how labor organizations can actively contribute to the broader movement for environmental justice and ecosocialist transformation. This study not only informs the ongoing discourse on the intersection of labor and climate activism but also inspires future collaborations for anti-capitalist climate justice.

description: This presentation is a part of the course "Mediating Romance Language Literatures in a Global World" given at the master's level at Stockholm University. The course aims to discuss the historical and social-cultural factors that have contributed to promote or hinder literature mediation from the Romance language area in Scandinavia, especially in Sweden. In this presentation, the focus will be made on some specific editorial strategies with the example of some Francophone writers (Kim Thúy for instance) who were translated into Swedish quite early. Then, a final reflection will be made on the difficulty of categorizing Francophone literature/French literature.

description: This paper describes a near-UV/VIS study of a pyrene:H_2O interstellar ice analogue at 10 K using optical absorption spectroscopy. A new experimental approach makes it possible to irradiate the sample with vacuum ultraviolet (VUV) light (7-10.5 eV) while simultaneously recording spectra in the 240-1000 nm range with subsecond time resolution. Both spectroscopic and dynamic information on VUV processed ices are obtained in this way. This provides a powerful tool to follow, in-situ and in real time, the photophysical and photochemical processes induced by VUV irradiation of a polycyclic aromatic hydrocarbon containing inter- and circumstellar ice analogue. Results on the VUV photolysis of a prototype sample - strongly diluted pyrene in H_2O ice - are presented. In addition to the pyrene cation (Py+), other products - hydroxypyrene (PyOH), possibly hydroxypyrene cation (PyOH+), and pyrene/pyrenolate anion (Py-/PyO-) - are observed. It is found that the charge remains localized in the ice, also after the VUV irradiation is stopped. The astrochemical implications and observational constraints are discussed.

description: Polyglyphanodontians were a dominant terrestrial lizard group during the Cretaceous. They were mainly distributed across Laurasia but show their greatest diversity in the Upper Cretaceous deposits of China and Mongolia. Several of the Asian taxa were comparatively large, with robust skulls and a dentition specialized for herbivory. Two polyglyphanodontian genera, Tianyusaurus from China and Polyglyphanodon from North America, are unusual in having developed a complete, or near complete, lower temporal bar. Here we describe a third polyglyphanodontian with a complete lower temporal bar, Yechilacerta yingliangia gen. et sp. nov., from the Upper Cretaceous of Jiangxi Province, southern China. These deposits have also yielded specimens of Tianyusaurus, but the new genus differs from Tianyusaurus in several key aspects of skull and dental morphology, including the presence of coarse pustulate cranial sculpture, and the absence of maxillary caniniform teeth. Phylogenetic analysis places the new genus and species as the sister taxon to Tianyusaurus, with both taxa nested among East Asian gilmoreteiids. Previous phylogenetic analyses using morphological characters have mostly placed polyglyphanodontians close to extant teiioid lizards, but our analyses, using a constraint tree for squamates based on published molecular phylogenies, placed Polyglyphanodontia closer to Iguania. However, a more comprehensive review is needed to resolve their relationships. http://zoobank.org/urn:lsid:zoobank.org:pub:53B9CE04-E600-48AE-AC98-7476A949BCBD

description: Capacitors are ubiquitous in electronic and electrical devices. In this article, we study -- both theoretically and experimentally -- the charging and discharging of capacitors using active control of a voltage source. The energy of these processes is analyzed in terms of work and heat. We show how to approach the quasistatic regime by slowing down the charging or discharging processes. Conversely, we study the price to be paid in terms of Joule heat when we speed up these processes. Finally, we develop optimal processes that minimize energy consumption for a finite charging time. Our work combines fundamental concepts from thermodynamics, classical mechanics and electrical circuits, thus blurring the artificial frontiers at the undergraduate level between these disciplines. Also, it provides a simple example of a prominent problem in current science, the optimization of energy resources. Moreover, our study lends itself well to an experimental project in the classroom, involving computer control of a voltage source, data acquisition, and processing.

description: We discuss the ill conditioning of the matrix for the discretised Poisson equation in the small aspect ratio limit, and motivate this problem in the context of nonhydrostatic ocean modelling. Efficient iterative solvers for the Poisson equation in small aspect ratio domains are crucial for the successful development of nonhydrostatic ocean models on unstructured meshes. We introduce a new multigrid preconditioner for the Poisson problem which can be used with finite element discretisations on general unstructured meshes; this preconditioner is motivated by the fact that the Poisson problem has a condition number which is independent of aspect ratio when Dirichlet boundary conditions are imposed on the top surface of the domain. This leads to the first level in an algebraic multigrid solver (which can be extended by further conventional algebraic multigrid stages), and an additive smoother. We illustrate the method with numerical tests on unstructured meshes, which show that the preconditioner makes a dramatic improvement on a more standard multigrid preconditioner approach, and also show that the additive smoother produces better results than standard SOR smoothing. This new solver method makes it feasible to run nonhydrostatic unstructured mesh ocean models in small aspect ratio domains.

description: We have combined the thermo-chemical disc code ProDiMo with the Monte Carlo radiative transfer code MCFOST to calculate a grid of ~300000 circumstellar disc models, systematically varying 11 stellar, disc and dust parameters including the total disc mass, several disc shape parameters and the dust-to-gas ratio. For each model, dust continuum and line radiative transfer calculations are carried out for 29 far IR, sub-mm and mm lines of [OI], [CII], 12CO and o/p-H2O under 5 inclinations. The grid allows to study the influence of the input parameters on the observables, to make statistical predictions for different types of circumstellar discs, and to find systematic trends and correlations between the parameters, the continuum fluxes, and the line fluxes. The model grid, comprising the calculated disc temperatures and chemical structures, the computed SEDs, line fluxes and profiles, will be used in particular for the data interpretation of the Herschel open time key programme GASPS. The calculated line fluxes show a strong dependence on the assumed UV excess of the central star, and on the disc flaring. The fraction of models predicting [OI] and [CII] fine-structure lines fluxes above Herschel/PACS and Spica/SAFARI detection limits are calculated as function of disc mass. The possibility of deriving the disc gas mass from line observations is discussed.

Assessment of the stability and quantification of agitated saline contrast to assess blood flow through intrapulmonary arteriovenous anastomoses
Creators: name: Boulet, Lindsey M.
Publisher: name: University of British Columbia
Year: 2024

description: Substantial research has been conducted on right-to-left shunts in healthy humans using transthoracic agitated saline contrast echocardiography (TTSCE), however, TTSCE is limited by an inherent instability and an imprecise method of quantification. The goal of this dissertation is twofold: (1) to assess the stability of TTSCE using an in vitro model of the pulmonary circulation under varying environmental conditions, and (2) to determine the feasibility of measuring shunt fraction by modelling ultrasound contrast data. Study 1 aims to determine if the stability of saline contrast microbubbles is altered under gas conditions that match mixed venous (5.9 % CO2, 4.9 % O2) blood and hyperoxic conditions (100% O2) at varying flow rates (1.8, 2.8, 4.3 & 6.8 l/min). At higher flow rates (4.3 & 6.8 l/min), less ultrasound contrast was lost in the hyperoxic vs mixed venous gas condition whereas no significant difference was observed at low flow rates (1.8 – 2.8 l/min). The purpose of study 2 was to determine if hypobaria (simulated altitude: 5050m) affects microbubble stability. Using the experimental design from study 1, it was determined that reduced barometric pressure did not significantly alter microbubble stability. Finally, study 3 was designed to determine if mathematical modelling can be applied to saline contrast data from TTSCE to quantify a simulated shunt fraction. Saline contrast was injected into an in vitro model of the pulmonary circulation that was adapted to include an adjustable shunt vessel. Results show a good agreement between shunt flow measured using modeled data and actual shunt flow at higher flow rates but was less reliable at low flow rates. In summary, we determined that the stability of saline contrast microbubbles generated using TTSCE is not affected by hypobaria and is only slightly increased in hyperoxic conditions compared to mixed venous conditions suggesting the technique can be employed in a wide variety of environmental conditions. Furthermore, this work demonstrates that mathematical modelling applied to saline contrast ultrasound data can be used to assess shunt fraction, however it loses some fidelity at low flow rates and with small shunt fractions.

description: The buckling behavior of cylindrical shells has gained significant interest over the past century due to its rich nonlinear behavior and broad engineering applications. While the buckling of cylindrical shells under a single load (e.g., compression or torsion) has been extensively studied, the buckling behavior under combined torsional and axial loads remains largely unexplored. In this paper, based on a combination of experiments, theoretical modeling, and finite element simulations, we systematically investigate the buckling and post-buckling behavior of cylindrical shells under combined torsional and axial loads. Three different types of combined loads are considered: compression with pre-torsion, torsion with pre-tension, and torsion with pre-compression. The theoretical model is established within the framework of the Donnell shell theory and solved using the Galerkin method, through which the critical buckling load, critical circumferential wavenumber, buckling pattern, and post-buckling equilibrium path of clamped-clamped thin cylindrical shells under various types of loads can be determined. The theoretical predictions agree well with finite element simulations and qualitatively capture the various buckling phenomena observed in the experiments. It is found that cylindrical shells exhibit quite different post-buckling behavior under combined loads compared to under a single compressive or torsional load. For instance, when a clamped-clamped thin cylindrical shell is subjected to pure torsion or torsion with a relatively small pre-compression, it consistently shows a diagonal-shaped pattern during deformation. However, with a relatively large pre-compression, the shell transitions from a diagonal-shaped pattern to a twisted diamond-shaped pattern.

description: An analytical expression for the spin-averaged amplitude squared of the rare muon decay $μ^+ \to e^+e^-e^+ν_e\bar{ν_μ}$ is calculated. Monte Carlo phase space simulation using the analytical expression for the amplitude has been used to get various differential distributions of charged leptons. The approximate analytical expression for the total energy spectrum of charged leptons near the end point is presented. The dependence of branching ratio on cuts in total energy of charged leptons is studied taking into account an experimental energy resolution. It is shown that the measured branching ratio is very sensitive to the energy resolution.

description: For the first order Metal Insulator Transitions we show that together with the d.c conductance zero there is a second critical point, where the dielectric constant becomes zero and further turns negative. At this point the metallic reflectivity sharply increases. The two points can be separated by a Phase Separation State in a 3D disordered system, but may tend to merge in 2D. For illustration we evaluate the dielectric function in a simple effective medium approximation and show that at the second point it turns negative. We reproduce the experimental data on a typical Mott insulator like MnO, demonstrating the presence of the two points clearly. We discuss other experiments for studies of the phase separation state and a similar phase separation in superconductors with insulating inclusions.

description: The Wealden Group of southern England was deposited by rivers, on floodplains and in lagoons during the Early Cretaceous. Two historically significant ankylosaurs, Polacanthus and Hylaeosaurus, are currently known from its deposits; Hylaeosaurus from the ‘lower Wealden fauna’ and Polacanthus from the ‘upper Wealden fauna’. Here, we describe a new genus and species of ankylosaur from the Wessex Formation of the Isle of Wight, which is characterized by numerous postcranial autapomorphies. Vectipelta barretti gen. et sp. nov. is 6–8 million years older than Polacanthus, and at least 3 million years younger than Hylaeosaurus, suggesting a more complicated pattern of faunal turnover in the Wealden Group than previously realized. Vectipelta does not appear to be closely related to either of the other Wealden taxa, but instead is found in a clade with two Chinese ankylosaurs, suggesting a complex pattern of dispersal to and from Europe, North America and Asia during the Early Cretaceous. The historic practise of cataloguing all ankylosaur material from the Wessex Formation as ‘Polacanthus’ has potentially prevented a diversity of taxa from being discovered, and new and existing material in museum collections should be re-appraised using an autapomorphy-driven approach. http://zoobank.org/urn:lsid:zoobank.org:pub:0B19B56E-971D-4316-A92C-FC9AB29BBC38

description: Quasiparticle calculations are performed to investigate the electronic band structures of various polymorphs of Hf and Zr oxides. The corrections with respect to density-functional-theory results are found to depend only weakly on the crystal structure. Based on these bulk calculations as well as those for bulk Si, the effect of quasiparticle corrections is also investigated for the band offsets at the interface between these oxides and Si assuming that the lineup of the potential at the interface is reproduced correctly within density-functional theory. On the one hand, the valence band offsets are practically unchanged with a correction of a few tenths of eV. On the other hand, conduction band offsets are raised by 1.3--1.5 eV. When applied to existing calculations for the offsets at the density-functional-theory level, our quasiparticle corrections provide results in good agreement with the experiment.

Exploring long-term patient satisfaction with total knee arthroplasty : a mixed methods study
Creators: name: Randall, Ellen C.
Publisher: name: University of British Columbia
Year: 2024

description: Total knee arthroplasty (TKA) is the most common joint replacement surgery in Canada. Despite longstanding high volumes, there is persistent evidence that TKA patient satisfaction is not as high as desired, with studies reporting that 10%–20% of patients are not satisfied. Reducing this percentage is a priority. While research exploring drivers of TKA satisfaction exists, new actionable insights into the high numbers of unsatisfied patients is needed. This mixed methods study brought three lenses (quantitative, qualitative, mixed methods integration) to bear on the question: What factors explain variation in long-term satisfaction following primary TKA surgery? The quantitative component used bivariate analyses to analyze responses (n=314) to a patient questionnaire completed three years post-surgery, assessing associations between predictors and a binary satisfaction measure (satisfied/not satisfied). Variation in satisfaction was associated with symptoms such as pain or mental health conditions such as anxiety. The qualitative component was a grounded theory study in which 27 purposefully sampled members of the quantitative sample were interviewed about TKA satisfaction. Interviewees tended not to reflect on satisfaction, instead describing their knee’s “adequacy”: how it felt, functioned, and met their expectations. Central to their stories was the process of adapting to the TKA knee; experiences adapting shaped perceptions of adequacy. In the integration component, key concepts from the quantitative and qualitative components were compared using an analytic framework to evaluate how these concepts aligned. Quantitative and qualitative components were confirmatory in finding a relationship between current physical symptoms and lower assessments of satisfaction or adequacy, signalling a need for enhanced clinical support for patients whose symptoms don’t abate. Differences in representations of patient expectations in the two components highlights a need for a standard approach to this concept, with a focus on expectation fulfilment. Instances of non-alignment, where a concept was present in only one component, point to opportunities for future research. The integration analysis found complementarity in the concepts of “satisfaction” and “adequacy.” This suggests potential to reconceptualize satisfaction in ways more resonant with the patient perspective, bringing us closer to measuring—and improving—what matters to patients when assessing the success of TKA surgery.

description: Background This research probes probable role of elemene injection on pancreatic cancer employing network pharmacology and experimental validation. Materials and Methods GEO database were used to acquire genes which is differentially expressed between pancreatic cancer tissue with normal tissue. The vigorous energetic ingredients were identified consequent a reading search and the object genes of were obtained from BATMAN-TCM. Subsequently, a Venn diagram was constructed to visualize the common genes. Screening for survival-related genes was performed using the GEPIA database. Moreover, docking and co-immunoprecipitation studies were performed to verify the suggested contact between the elemene components and target genes. In vitro experiments using pancreatic cell lines, including Panc02, Mia PaCa-2, and Capan-1 and in vivo experiments using Panc02-injected C57BL/6 mice were conducted for further validation. Results Twenty-seven target genes that potentially mediate elemene’s effect on pancreatic cancer were obtained. The experiments verified that elemene injection suppresses pancreatic cancer cell expansion, blocks cells in S phase, and causes apoptosis by upregulating EPHX2 and downregulating EFNA5 in vitro and in vivo. Conclusions The mechanism may be related to induced EPHX2 overexpression and EFNA5 hypoexpression. Both EPHX2 and EFNA5 are new targets for pancreatic cancer treatment that require further investigation.

description: The electronic structures of FeAs-compounds strongly depend on the Fe-As bonding, which can not be described successfully by the local density approximation (LDA). Treating the multi-orbital fluctuations from $ab$-$initio$ by LDA+Gutzwiller method, we are now able to predict the correct Fe-As bond-length, and find that Fe-As bonding-strength is 30% weaker, which will explain the observed "soft phonon". The bands are narrowed by a factor of 2, and the $d_{3z^2-r^2}$ orbital is pushed up to cross the Fermi level, forming 3-dimensional Fermi surfaces, which suppress the anisotropy and the ($π,π$) nesting. The inter-orbital Hund's coupling $J$ rather than $U$ plays crucial roles to obtain these results.

description: We investigate the question of distinguishing between different microstates of the D1-D5 system (with charges Q_1 and Q_5), by scattering with an incoherent beam, composed of a supergravity probe, with central energy E_0 and width (ΔE). The scattering is studied in the dual CFT description in the orbifold limit for finite R, where R is the radius of the circle on which the D1 branes are wrapped. When R(ΔE) >> 1, the absorption cross-section is found to be independent of the microstate and identical to the leading semiclassical answer computed from the naive geometry. For smaller (ΔE), the answer depends on the particular microstate, which we examine for both typical and atypical microstates. We derive an upper bound for the leading correction to the cross-section when 1/R >> ΔE >> (the average energy gap 1/{R [sqrt(Q_1Q_5)]}. For a typical state the bound is proportional to the area of the stretched horizon, [\sqrt(Q_1 Q_5)], up to [log (Q_1Q_5)] terms. Furthermore, when E_0 << (ΔE), the proportionality constant is a pure number independent of all energy scales. Numerical calculations using Lorentzian profiles show that the actual value of the correction is in fact proportional to [sqrt(Q_1Q_5)] without the logarithmic factor. We offer some speculations about how this result can be consistent with a resolution of the naive geometry by higher derivative corrections to supergravity.

description: In this paper, we present a distributed implementation of a network based multi-objective evolutionary algorithm, called EMO, by using Offspring. Network based evolutionary algorithms have proven to be effective for multi-objective problem solving. They feature a network of connections between individuals that drives the evolution of the algorithm. Unfortunately, they require large populations to be effective and a distributed implementation can leverage the computation time. Most of the existing frameworks are limited to providing solutions that are basic or specific to a given algorithm. Our Offspring framework is a plug-in based software environment that allows rapid deployment and execution of evolutionary algorithms on distributed computing environments such as Enterprise Clouds. Its features and benefits are presented by describing the distributed implementation of EMO.

description: We present a microscopic model for coherent pion production off nuclei induced by neutrinos. This model is built upon a model for single nucleon processes that goes beyond the usual Delta dominance by including non resonant background contributions. We include nuclear medium effects: medium corrections to Delta$ properties and outgoing pion absortion via an optical potential. This results in major modifications to cross sections for low energy experiments when compared with phenomenological models like Rein-Sehgal's.

description: We propose a new structural model for the Si(111)-(5x2)-Au reconstruction. The model incorporates a new experimental value of 0.6 monolayer for the coverage of gold atoms, equivalent to six gold atoms per 5x2 cell. Five main theoretical results, obtained from first-principles total-energy calculations, support the model. (1) In the presence of silicon adatoms the periodicity of the gold rows spontaneously doubles, in agreement with experiment. (2) The dependence of the surface energy on the adatom coverage indicates that a uniformly covered phase is unstable and will phase-separate into empty and covered regions, as observed experimentally. (3) Theoretical scanning tunneling microscopy images are in excellent agreement with experiment. (4) The calculated band structure is consistent with angle-resolved photoemission spectra; analysis of their correspondence allows the straightforward assignment of observed surface states to specific atoms. (5) The calculated activation barrier for diffusion of silicon adatoms along the row direction is in excellent agreement with the experimentally measured barrier.

description: Numerical simulations of the current and field distribution in thin superconducting films are carried out for a given material law Jc(B) and as a function of the applied field H, taking the sample's self-field into account. The dependence of the critical current density on the applied field Jc(H) is computed for comparison with experiment, considering the geometry of transport measurements. We show that extrapolating the high field power law Jc \propto B^{-α} to the lowest fields results in a finite critical current at zero applied field Jc(H=0), despite the singularity of Jc(B). Moreover, particular features of the experiment, such as a low field plateau in Jc(H), are reproduced and found to be determined by the self-field.

description: O presente documento consiste em uma apostila para as aulas práticas dos cursos de extensão oferecidos pelo Projeto Cores do Nordeste, do Departamento de Geologia da Universidade Federal de Pernambuco. O projeto tem entre seus principais objetivos a pesquisa por pigmentos naturais de fontes diversas e a produção de materiais artísticos artesanais para uso profissional e escolar. O acúmulo de conhecimento envolvendo essas temáticas permitiu a criação e oferta de diversos cursos, tanto para professores da Educação Básica e estudantes de licenciatura, quanto para estudantes e profissionais da área de Artes Visuais, com ênfases diferentes conforme o público:

Para professores e estudantes de licenciatura os pigmentos e materiais artísticos artesanais são apresentados como recursos didáticos para a Educação Básica com ênfase no ensino de Geociências, Química, Biologia, Física, História e Artes.

Para profissionais e estudantes da área de Artes Visuais, os cursos possuem uma abordagem mais técnica e envolvem aprofundamento na produção de materiais artísticos artesanais para uso profissional com pigmentos sintéticos e naturais.

A oferta periódica destes cursos acarretou a necessidade de produzir um material didático próprio, representado por esta apostila. O texto está organizado em quatro partes – Pigmentos, Tintas Artísticas, Pastéis e Materiais Escolares - onde são abordados tópicos como:

Propriedades químicas e físicas de pigmentos para uso artístico

The unequal pandemic: A qualitative study exploring the impact of the COVID-19 pandemic on migrant women in Milan, Italy

COVID-19 pandemic

description: The research presented in this poster starts from the assumption that migrants and women were among the groups most severely affected by the COVID-19 pandemic global disaster. By adopting an intersectional lens it can be inferred that migrant women were particularly vulnerable to its impacts, yet research targeting this group is still scant. Our study aimed to explore the multifaceted impact of the COVID-19 pandemic on migrant women living in Milan, Italy, investigating a broad spectrum of experiences and challenges. We conducted a phenomenological study using semi-structured interviews over the period September 2023 - January 2024 with 19 cisgender migrant women coming from 10 different countries, with a median age of 43 years. At the pandemic’s onset, 12 were undocumented migrants, four were documented, while three had obtained Italian citizenship. Most held informal job positions, primarily as domestic workers, and were impacted by the economic crisis triggered by the pandemic. Both before and during the pandemic, NGOs were the preferred entry point to the healthcare systems. Their psychological well-being was compromised by distance from family members and the extensive COVID-19 media coverage. Most of them disclosed vaccine skepticism, but adhered to the vaccination campaign due to its de-facto mandatory nature. Social isolation was identified as one of the least significant impacts. Overall, migrant women did not perceive themselves as a particularly vulnerable group, in general and as compared to migrant men and Italian women. As distrust emerged as a particularly significant issue, especially towards the Italian healthcare system, establishing trusting relationships beforehand is crucial for the effectiveness of disaster response efforts.
