description: Children with serious illness, including life-shortening and life-threatening illnesses, must contend with significant challenges related to limitations of their illness, the loss of physical functioning, and the threat of death. Social conceptions of childhood and death influence how children and adults understand serious illness and death in childhood. The ways in which children express the complexity of their experiences is not always as simple as making a verbal statement. In this philosophical hermeneutic inquiry, my aim was to explore how we might understand children’s experiences of serious illness from their perspectives and in their own “voices.” Six participants between the ages of seven and 17 years were interviewed to understand how children experience serious illness. Their “voices” included art, metaphor, and silence. The interpretive results generated from this research involve a different conception of children’s “voices,” their experiences of clinical places and relational spaces, physical and psychological apprehension in serious illness, and the silence that expresses inexplicable experiences. I conclude by exploring the practice implications for this research and the possibilities that children recognized for their own lives, despite the significant limitations that serious illness in childhood presents.
"No way to return" : agentic assemblies, switchback resistance, and spatializing Thomas Pynchon's narrative politics in Vineland
Creators: name: Stewart, Anne Catherine
Publisher: name: University of British Columbia
Year: 2012

description: This thesis focuses on one of the least acclaimed novels in Thomas Pynchon’s canon, Vineland. It was reviewed with disappointment by critics like Brad Leithauser, who writes that Vineland falters “chiefly through its failure in any significant degree to extend or improve upon what the author has done before.” I argue against such a reading, and position Vineland as a critical turning point for Pynchon’s work in which his articulation of the relationship between humans and nonhumans is dramatically refigured. I do this by reconsidering the history of American countercultural politics presented in Vineland in two distinct ways. First, attending to Pynchon’s critical interest in landscapes and urban spaces, I argue that the novel’s histories should be read as conceptual objects, materially coded into the landscape in such a way that they speak through these landscapes. Second, continuing to focus on ways in which space and materiality function in this novel, I draw out the nonhuman actors at work in the narrative in order to demonstrate a shift in Pynchon’s conceptualization of the relationship between what he often refers to as the animate and inanimate worlds. While his earlier novels posit an inanimate world that is threatening to humans, Vineland’s human-nonhuman dynamic is far more entangled in terms of its investment in how these actors function in assembly with each other. I pay particular attention to what Jane Bennett calls “agentic assemblages,” groupings of human and nonhuman materialities—a storm or a power grid, a city or a bioregion—that function together to author the spaces that they occupy in this novel. At stake here is a refiguring of historical agency as the product of a web of competing human and nonhuman discursive strategies. I argue that the novel’s narrative politics is one in which nonhumans have an authorial role, and that its form repeats this politics by deploying a spatial and discursive navigational strategy for human actors living in a world which is fundamentally nonanthropocentric. Through this narrative politics, Vineland emerges as a major contribution to late-20th century critical thought on spatiality, political ecology, materialist philosophy, and narrative theory.

description: We study how the presence of a background magnetic field, of intensity compatible with current observation constraints, affects the linear evolution of cosmological density perturbations at scales below the Hubble radius. The magnetic field provides an additional pressure that can prevent the growth of a given perturbation; however, the magnetic pressure is confined only to the plane orthogonal the field. As a result, the "Jeans length" of the system not only depends on the wavelength of the fluctuation but also on its direction, and the perturbative evolution is anisotropic. We derive this result analytically and back it up with direct numerical integration of the relevant ideal magnetohydrodynamics equations during the matter-dominated era. Before recombination, the kinetic pressure dominates and the perturbations evolve in the standard way, whereas after that time magnetic pressure dominates and we observe the anisotropic evolution. We quantify this effect by estimating the eccentricity $ε$ of a Gaussian perturbation in the coordinate space that was spherically symmetric at recombination. For perturbations at the sub-galactic scale, we find that $ε= 0.7$ at $z=10$ taking the background magnetic field of order $10^{-9}$ gauss.

description: This study investigated kindergarten through grade 12 moral education policy in Alberta for the period 2013-2024 with a twofold purpose. The first was to understand what comprised moral education in Alberta through the identification of explicit and implicit moral elements contained within recent and current policies. The second was to examine how moral education in Alberta, as reflected in its policy texts, reflected the pluralistic nature of Alberta society using a perspective grounded in the value pluralism of Isaiah Berlin. Through an interpretive process of conventional qualitative document content analysis, Alberta policy documents, including statutes, regulations, policies, curriculum guides, curriculum, and legislative Hansard, were examined for elements related to moral education. Three primary themes emerged from the data analysis: (a) the individual is viewed as a moral agent who focuses on their own success, others’ well-being and success, and making ethical decisions; (b) the good society is viewed as democratic and civil, embracing pluralism and diversity with some shared values; and (c) the school is a nexus of common and uncommon values in which systems, processes, and structures support common values and guide responses to the convergence of uncommon values present in society. Further, analyzing the identified themes and subthemes using a lens of Isaiah Berlin’s value pluralism showed that Alberta policies failed to substantively address the incommensurability and incompatibility of values. This study identified the need for a robust pluralist moral education that includes: pluralism as a core principal, toleration as an educational aim, engagement with agonistic conflicts, fostering of moral independence, critical dialogue and negotiation, and a focus on striving for a minimal threshold of negative liberty to enable the pursuit of universal values essential for human experience to better prepare them to coexist amongst deep and intractable differences about beliefs, commitments, and ways of life.

description: We consider the evolution of fronts by mean curvature in the presence of obstacles. We construct a weak solution to the flow by means of a variational method, corresponding to an implicit time-discretization scheme. Assuming the regularity of the obstacles, in the two-dimensional case we show existence and uniqueness of a regular solution before the onset of singularities. Finally, we discuss an application of this result to the positive mean curvature flow.

Evolution of Lactase Persistence: Turbo-Charging Adaptation in Growth Under the Selective Pressure of Maternal Mortality?

description: The emergence of the capacity to digest milk in some populations represents a landmark in human evolution, linking genetic change with a component of niche construction, namely dairying. Alleles promoting continued activity of the enzyme lactase through the life-course (lactase persistence) evolved in several global regions within the last 7,000 years. In some European regions, these alleles underwent rapid selection and must have profoundly affected fertility or mortality. Elsewhere, alleles spread more locally. However, the functional benefits underlying the rapid spread of lactase persistence remain unclear. Here, we set out the hypothesis that lactase persistence promoted skeletal growth, thereby offering a generic rapid solution to childbirth complications arising from exposure to ecological change, or to new environments through migration. Since reduced maternal growth and greater neonatal size both increase the risk of obstructed labour, any ecological exposure impacting these traits may increase maternal mortality risk. Over many generations, maternal skeletal dimensions could adapt to new ecological conditions through genetic change. However, this adaptive strategy would fail if ecological change was rapid, including through migration into new niches. We propose that the combination of consuming milk and lactase persistence could have reduced maternal mortality by promoting growth of the pelvis after weaning, while high calcium intake would reduce risk of pelvic deformities. Our conceptual framework provides locally relevant hypotheses to explain selection for lactase persistence in different global regions. For any given diet and individual genotype, the combination of lactase persistence and milk consumption would divert more energy to skeletal growth, either increasing pelvic dimensions or buffering them from worsening ecological conditions. The emergence of lactase persistence among dairying populations could have helped early European farmers adapt rapidly to northern latitudes, East African pastoralists adapt to sudden climate shifts to drier environments, and Near Eastern populations counteract secular declines in height associated with early agriculture. In each case, we assume that lactase persistence accelerated the timescale over which maternal skeletal dimensions could change, thus promoting both maternal and offspring survival. Where lactase persistence did not emerge, birth weight was constrained at lower levels, and this contributes to contemporary variability in diabetes risk.

It was proved by Wagner for fields of positive characteristic, but it remains wide open in the zero-characteristic case. We reduce Podewski's conjecture to the case of fields having a definable (in the pure field structure), well partial order with an infinite chain, and we conjecture that such fields do not exist. Then we support this conjecture by showing that there is no minimal field interpreting a linear order in a specific way; in our terminology, there is no almost linear, minimal field. On the other hand, we give an example of an almost linear, minimal group $(M,

description: The historical relationship between Indigenous people and the Chilean state has been distant, complex, and frankly contentious. Since the colonial period, this relationship has gone through different stages and slowly transformed to include Indigenous actors in formal political spaces in relevant entities, such as the Constitutional Convention, during the 2020-2023 constitutional process. The constitutional process was a novel situation which presented an opportunity for the Chilean State to address some of the historical demands of Indigenous people. This situation, where Indigenous groups accessed a formal political space to participate in the constitutional development to rule the country, turned into an opportunity to examine varied social relations that occur when Indigenous groups enter the formal political arena in Chile. This manuscript-based thesis uses situational analysis to explore the relationships across an array of human elements and discourses during the constitutional process vis-à-vis the political participation of Indigenous people and the recognition of their rights. In my analysis of the constitutional process, I found that the participation of Indigenous people was characterized by the simultaneous promise of greater political involvement and barriers to fully realizing it. The situation included competing discourses regarding the plurinational state as a proposed political model to recognize Indigenous people’s constitutional rights. These discourses were often animated by the potential implications of the model for citizens’ livelihoods and the state organization. Based on the complex sociopolitical dynamics involving Indigenous people in Chile’s constitutional process, this research has various empirical, theoretical, and methodological contributions to Latin American politics, education and situational analysis.

description: Studies on the selection of floral traits usually consider pollinators and sometimes herbivores. However, humans also exert selection on floral traits of ornamental plants. We compared the preferences of bumblebees (Bombus terrestris), thrips (Frankliniella occidentalis), and humans for flowers of snapdragon. From a cross of two species, Antirrhinum majus and Antirrhinum linkianum, we selected four Recombinant Inbred Lines (RILs). We characterised scent emission from whole flowers and stamens, pollen content and viability, trichome density, floral shape, size and colour of floral parts. We tested the preferences of bumblebees, thrips, and humans for whole flowers, floral scent bouquets, stamen scent, and individual scent compounds. Humans and bumblebees showed preferences for parental species, whereas thrips preferred RILs. Colour and floral scent, in combination with other floral traits, seem relevant phenotypes for all organisms. Remarkably, visual traits override scent cues for bumblebees, although, scent is an important trait when bumblebees cannot see the flowers, and methyl benzoate was identified as a key attractant for them. The evolutionary trajectory of flowers is the result of multiple floral traits interacting with different organisms with different habits and modes of interaction.

description: One of the stumbling blocks for studying the evolution of interstellar molecules is the lack of adequate knowledge of the rate co-efficients of various reactions which take place in the Interstellar medium and molecular clouds. Some of the theoretical models of rate coefficients do exist in the literature for computing abundances of the complex pre-biotic molecules. So far these have been used to study the abundances of these molecules in space. However, in order to obtain more accurate final compositions in these media, we find out the rate coefficients for the formation of some of the most important interstellar pre-biotic molecules by using quantum chemical theory. We use these rates inside our hydro-chemical model to find out the chemical evolution and the final abundances of the pre-biotic species during the collapsing phase of a proto-star. We find that a significant amount of various pre-biotic molecules could be produced during the collapsing phase of a proto-star. We study extensively the formation these molecules via successive neutral-neutral and radical-radical/radical-molecular reactions. We present the time evolution of the chemical species with an emphasis on how the production of these molecules varies with the depth of a cloud. We compare the formation of adenine in the interstellar space using our rate-coefficients and using those obtained from the existing theoretical models. Formation routes of the pre-biotic molecules are found to be highly dependent on the abundances of the reactive species and the rate coefficients involved in the reactions. Presence of grains strongly affect the abundances of the gas phase species. We also carry out a comparative study between different pathways available for the synthesis of adenine, alanine, glycine and other molecules considered in our network.

In each case, we estimate the expected Wasserstein distance from the empirical spectral measure to a deterministic reference measure, and prove a concentration result for that distance. As a consequence we obtain almost sure convergence of the empirical spectral measures in all cases.

description: This thesis presents an advanced Intelligent Monitoring System (IMS) specifically designed for comprehensive traffic scene analysis and video anomaly detection. As urban environments increasingly depend on CCTV technology, the demand for automated systems capable of efficiently analyzing vast amounts of video data has become critical. The proposed IMS integrates both appearance and motion analysis modules, enabling the effective monitoring of traffic environments. By extracting features in different levels, the proposed system facilitates accurate detection and localization of objects within dynamic scenes. A key innovation of this research is the development of a novel anomaly detection algorithm that classifies detected anomalies into three categories: point, collective, and contextual. This classification is further enhanced by investigating the underlying causes of anomalies, providing deeper insights into abnormal behaviors within traffic scenarios. The system also employs multiple assessment baselines, allowing for adaptive analysis of incoming video frames, which enables the differentiation of anomalies that may be deemed normal in one context but anomalous in another. Extensive simulations conducted on real-world datasets, including data from the City of Calgary, showcase the significant advancements in detection performance achieved by the proposed methodologies. The proposed IMS not only processes individual frames but also generates comprehensive reports detailing object detection, classification, and motion characteristics. By effectively distinguishing between different types of anomalies and considering multiple baselines, the system provides valuable insights into traffic behaviors and incident responses. Overall, this research contributes a robust end-to-end IMS equipped with a cutting-edge anomaly detection algorithm that surpasses traditional methods, establishing a versatile framework for real-time video monitoring applications. This work lays a strong foundation for future advancements in intelligent surveillance systems, ultimately contributing to improved urban traffic management and safety.

description: Iranian immigrants are among Canada's top ten large immigrant nationalities. Moving to a new country and adapting to a new culture can be stressful and affect immigrants' physical and mental well-being. In order to mitigate these negative effects, social-emotional skills (SE) can equip people with the skills to manage stress, demonstrate emotions in a healthy way, and develop positive relationships. In this regard, parents have a vital role to play in enhancing their children’s social-emotional skills, but supporting skill development may be more challenging for immigrant parents. To fill a gap in the research on this subject, the current study investigated the perspectives of Iranian immigrant parents regarding the development of their children's social-emotional skills. Of interest was their perspectives of what skills they deem important, how SE skills can benefit their children, how they support skill development, and the challenges they face developing skills. This study utilized a qualitative approach with thematic analysis. Six Iranian immigrant parents (five mothers and one father) who met the inclusion criteria participated in semi-structured interviews. In this thesis, the researcher used a Thematic analysis to examine the data, leading in four main themes: (a) essential competencies; (b) benefits of skills; (c) strategies to foster children’s skills; (d) challenges faced by parents. Overall, the current study provides valuable understanding of the needs, values, strategies and challenges of immigrant parents, equipping professionals to support these families more effectively.

description: Abstract: Pdr5, a member of the extensive ABC transporter superfamily, is representative of a clinically relevant subgroup involved in pleiotropic drug resistance. Pdr5 and its homologues drive drug efflux through uncoupled hydrolysis of nucleotides, enabling organisms such as baker’s yeast and pathogenic fungi to survive in the presence of chemically diverse antifungal agents. Here, we present the molecular structure of Pdr5 solved with single particle cryo-EM, revealing details of an ATP-driven conformational cycle, which mechanically drives drug translocation through an amphipathic channel, and a clamping switch within a conserved linker loop that acts as a nucleotide sensor. One half of the transporter remains nearly invariant throughout the cycle, while its partner undergoes changes that are transmitted across inter-domain interfaces to support a peristaltic motion of the pumped molecule. The efflux model proposed here rationalises the pleiotropic impact of Pdr5 and opens new avenues for the development of effective antifungal compounds.
Unifying typical entanglement and coin tossing: on randomization in probabilistic theories

description: It is well-known that pure quantum states are typically almost maximally entangled, and thus have close to maximally mixed subsystems. We consider whether this is true for probabilistic theories more generally, and not just for quantum theory. We derive a formula for the expected purity of a subsystem in any probabilistic theory for which this quantity is well-defined. It applies to typical entanglement in pure quantum states, coin tossing in classical probability theory, and randomization in post-quantum theories; a simple generalization yields the typical entanglement in (anti)symmetric quantum subspaces. The formula is exact and simple, only containing the number of degrees of freedom and the information capacity of the respective systems. It allows us to generalize statistical physics arguments in a way which depends only on coarse properties of the underlying theory. The proof of the formula generalizes several randomization notions to general probabilistic theories. This includes a generalization of purity, contributing to the recent effort of finding appropriate generalized entropy measures.

description: A nonlinear kinetic equation for nonrelativistic quantum plasma with electromagnetic interaction of particles is obtained in the Hartree's mean-field approximation. It is cast in a convenient form of Vlasov-Boltzmann-type equation with "quantum interference integral", that allows for relatively straightforward modification of existing classical Vlasov codes to incorporate quantum effects (quantum statistics and quantum interference of overlapping particles wave functions), without changing the bulk of the codes. Such modification (upgrade) of existing Vlasov codes may provide a direct and effective path to numerical simulations of nonlinear electrostatic and electromagnetic phenomena in quantum plasmas, especially of processes where kinetic effects are important (e.g., modulational interactions and stimulated scattering phenomena involving plasma modes at short wavelengths or high-order kinetic modes, dynamical screening and interaction of charges in quantum plasma, etc.) Moreover, numerical approaches involving such modified Vlasov codes would provide a useful basis for theoretical analyses of quantum plasmas, as quantum and classical effects can be easily separated there.

description: Genomic analyses have become fundamental in advancing our understanding of species conservation. Bull trout (Salvelinus confluentus), a charr native to northwestern North America, face population declines and require protection to ensure their persistence and survival. In my thesis, I used genetic loci known as Single Nucleotide Polymorphisms (SNPs) to investigate the genetic status of bull trout across Alberta. My two main objectives were to: 1) assess the extent of hybridization between bull trout and brook trout (S. fontinalis), and 2) examine the genetic structure and diversity of bull trout across Alberta’s Eastern Slopes. Our results indicate that while hybridization outcomes vary by site, post-F1 hybridization was low. This suggests that a loss of demographic output to F1 hybrids is likely the greatest impact from hybridization on bull trout populations in Alberta. From assessing genetic structure, clear genetic differentiation of bull trout was also observed between the two bull trout Designatable Units, the Western Arctic and Saskatchewan-Nelson, suggesting the presence of two distinct populations in northern and southern Alberta. Additionally, within-watershed diversity was also observed from this analysis, indicating that a high amount of local diversity contributes to bull trout exhibiting a hierarchical metapopulation structure. These findings suggest that management actions should be implemented at a local scale to protect the local adaptations and genetic integrity of bull trout.

description: With the advent of laser frequency combs, coherent light sources that offer equally-spaced sharp lines over a broad spectral bandwidth have become available. One decade after revolutionizing optical frequency metrology, frequency combs hold much promise for significant advances in a growing number of applications including molecular spectroscopy. Despite its intriguing potential for the measurement of molecular spectra spanning tens of nanometers within tens of microseconds at Doppler-limited resolution, the development of dual-comb spectroscopy is hindered by the extremely demanding high-bandwidth servo-control conditions of the laser combs. Here we overcome this difficulty. We experimentally demonstrate a straightforward concept of real-time dual-comb spectroscopy, which only uses free-running mode-locked lasers without any phase-lock electronics, a posteriori data-processing, or the need for expertise in frequency metrology. The resulting simplicity and versatility of our new technique of adaptive dual-comb spectroscopy offer a powerful transdisciplinary instrument that may spark off new discoveries in molecular sciences.

description: Asthma, a chronic respiratory condition affecting 10\% of Canada’s population in 2021, underscores the critical need for equitable and timely access to health facilities, particularly during emergencies. Transportation systems are vital for enabling access to these services; however, socioeconomic disparities and transportation limitations often restrict access for vulnerable populations. This thesis examines how transportation modes influence equitable access to health facilities for pediatric asthma patients, using Calgary as a case study. It explores a framework to improve transportation equity across traffic analysis zones to better serve disadvantaged groups. Two methods were employed to measure accessibility: the reachability-based method and the two-step floating catchment area method. Accessibility indexes were calculated for Calgary’s traffic analysis zones across three transportation modes—personal vehicles, public transit, and taxis—considering five-time slots during the day for emergency and non-emergency scenarios. Different travel thresholds and budgets were analyzed to identify inequities across zones. Equity was evaluated using horizontal and vertical equity techniques. Horizontal equity was assessed through the Gini coefficient, while vertical equity considered socioeconomic factors, pediatric asthma patients, and accessibility indexes to prioritize zones needing improved access to health facilities. The findings show that personal vehicles provide the highest access to health facilities across most time slots and travel budgets, making them the primary mode for accessing health facilities, especially in emergencies. Taxis are unaffordable at low budgets, while public transit often fails to offer sufficient accessibility during emergencies, particularly at night when available health facilities are limited. In non-emergency scenarios, taxis offer comparable accessibility at higher budgets. Vertical equity analysis highlighted zones with significant socioeconomic vulnerability and high asthma rates but low access as priorities for action. This research emphasizes the importance of incorporating equity into transportation planning to enhance public health outcomes. Policymakers should adopt a framework to prioritize underserved zones with greater accessibility needs while addressing both horizontal and vertical inequities. Future studies should address limitations by including weekend data and health facility capacity to provide a more comprehensive analysis of accessibility needs and their equity impacts.

Burning questions : examining the role of the Geoweb in understanding the human impacts of the Okanagan Mountain Park Fire

description: As online technologies evolve, the potential of the Geospatial Web (or Geoweb) to harness the collective knowledge of the general public is beginning to be realized. Using the Geoweb, people can volunteer their geographic information related to their own experiences to enable increased knowledge dissemination and give their fading memory some permanence. In the case of the 2003 Okanagan Mountain Park Fire, a 25,000-hectare forest fire that burned 238 homes and led to the evacuation of almost 30,000 people, these memories need to be captured soon or they will be forgotten. Collaborating with the Kelowna Fire Museum and Education Centre, this project follows the creation of an online participatory map capable of displaying each day of the fire in a stimulating and interactive way. It allows participants to better understand both the fire itself and the wide range of experiences and impacts by allowing participants to contribute their own information, whether photographs, videos, or text, and to comment on the contributions of others. Aside from the practical application of the tool, this community-based participatory research examines influences on an individual‘s willingness to volunteer geographic experiences related to the Okanagan Mountain Park fire through participant observation and six unstructured interview-workshops. Results examine participant engagement in terms of passive or active map use, perspectives of participants-as-experts and broader themes of whether the tool can educate and preserve information about this event for the museum. Results demonstrate that while the mapping tool allows users to engage with the spatial and cultural implications of the fire in an interactive way, it is difficult to encourage passive users to actively add points or discussions to the map. Although designed to be highly case-specific, the research raises broader questions about 'expert-ness' in participatory mapping and participation, which are applicable at a much broader level. Ultimately, this research considers the future of this tool and similar tools and whether volunteered geographic information works.

description: Intervertebral disc degeneration of the cervical spine is prevalent in aging adults with symptomatic cases often requiring surgical intervention. Cervical total disc arthroplasty (cTDA) is a surgical treatment for disc degeneration that aims to preserve natural motion of the spine and avoid adjacent segment degeneration. Despite low re-operation rates associated with cTDA, patient outcomes vary, and kinematic effects remain poorly understood. Understanding these effects via in vivo characterization could help address complications of cTDA and improve patient outcomes. This study implemented dual fluoroscopy to evaluate pre- and post-cTDA intervertebral rotations, translations, and endplate proximities to assess the impact of cTDA on in vivo cervical spine kinematics. Five asymptomatic control participants and two surgical participants undergoing cTDA were recruited. Participants underwent computed tomography and dual fluoroscopy imaging during dynamic movements. Model-based tracking matched subject-specific vertebral bone models to each dual fluoroscopy sequence with high accuracy (0.97 mm and 1.4°) and intervertebral rotations, translations, and bone-to-bone proximities were computed. The control pilot study verified the data collection and processing protocols yielded baseline data consistent with literature, although there was notable variability for some trials. Post-cTDA rotation patterns were similar to those of the controls, suggesting increased mobility at both treated and adjacent motion segments. Translations also increased post-cTDA, with some magnitudes exceeding one standard deviation above the control means, potentially indicating instability. Proximity measures indirectly described local disc height and illustrated the coupled motion patterns throughout movement, further emphasizing the value of three-dimensional in vivo kinematic approaches for studying the cervical spine. These kinematic measures have the potential to elucidate the complex coupled motion of the cervical spine post-cTDA and will be valuable for informing future artificial disc designs.
