description: Systems of housing in the Northwest Territories have long been insufficiently resourced to meet the region’s urgent levels of housing need. Further complications arise from histories of ineffective policy. Housing indicators show a state of crisis that appears to be more extreme than ever, while complex systemic factors challenge the delivery of effective solutions. This research explores the housing system in the Dene community Rádeyı̨lı̨ Kǫ́ (Fort Good Hope), Northwest Territories, as a case study for a ‘non-market’ northern, remote, Indigenous community. The methodology uses qualitative and quantitative analysis, participatory action research, and a design thinking approach. A historical review of housing policy and outcomes identifies how the crisis has evolved, and is followed by a comparative analysis of current housing conditions and key contributing factors. A potential intervention is outlined, in terms of recommendations for a transitional model of homeownership that responds effectively to the economic, social, environmental, and institutional context in the community of Fort Good Hope. The research proposes a framework for resilience in interdisciplinary and multiscalar terms as a response to the profound vulnerabilities of northern housing systems, with the potential for replicability in other communities or contexts.

description: We report evidence for extended gamma-ray emission from the Virgo, Fornax and Coma clusters based on a maximum-likelihood analysis of the 3-year Fermi-LAT data. For all three clusters, excess emission is observed within three degrees of the center, peaking at the GeV scale. This emission cannot be accounted for by known Fermi sources or by the galactic and extragalactic backgrounds. If interpreted as annihilation emission from supersymmetric dark matter (DM) particles, the data prefer models with a particle mass in the range 20-60 GeV annihilating into the b-bbar channel, or 2-10 GeV and >1 TeV annihilating into mu-mu final states. Our results are consistent with those obtained by Hooper and Linden from a recent analysis of Fermi-LAT data in the region of the Galactic Centre. An extended DM annihilation profile dominated by emission from substructures is preferred over a simple point source model. The significance of DM detection is 4.4 sigma in Virgo and lower in the other two clusters. We also consider the possibility that the excess emission arises from cosmic ray (CR) induced gamma-rays, and infer a CR level within a factor of three of that expected from analytical models. However, the significance of a CR component is lower than the significance of a DM component, and there is no need for such a CR component in the presence of a DM component in the preferred DM mass range. We also set flux and cross-section upper limits for DM annihilation into the b-bbar and mu-mu channels in all three clusters.

description: We address a fundamental mismatch between the combinations of dynamics that occur in cyber-physical systems and the limited kinds of dynamics supported in analysis. Modern applications combine communication, computation, and control. They may even form dynamic distributed networks, where neither structure nor dimension stay the same while the system follows hybrid dynamics, i.e., mixed discrete and continuous dynamics. We provide the logical foundations for closing this analytic gap. We develop a formal model for distributed hybrid systems. It combines quantified differential equations with quantified assignments and dynamic dimensionality-changes. We introduce a dynamic logic for verifying distributed hybrid systems and present a proof calculus for this logic. This is the first formal verification approach for distributed hybrid systems. We prove that our calculus is a sound and complete axiomatization of the behavior of distributed hybrid systems relative to quantified differential equations. In our calculus we have proven collision freedom in distributed car control even when an unbounded number of new cars may appear dynamically on the road.

description: Perinatal stroke (PS) is a focal, vascular brain injury that often damages the motor system and can leave patients with lifelong motor disability in the form of hemiparetic cerebral palsy. Current treatment is limited to waiting for the appearance of clinical signs and rehabilitation therapy; however, non-invasive brain stimulation is an emerging area of interest for this population. Transcranial direct current stimulation (tDCS) is a safe, non-invasive method of applying weak electrical current to the brain to enhance motor learning. How tDCS may alter motor cortex chemistry is unclear, however magnetic resonance spectroscopy (MRS) allows us to study brain metabolites and their changes in vivo. It is unknown how γ-aminobutyric acid (GABA), a primary inhibitory neurotransmitter may be altered in the motor cortices of children with PS and how it may change following intervention. Our study investigated the underlying neurochemical changes in children with perinatal stroke following intensive motor therapy and non-invasive brain stimulation interventions. Of those who were recruited and completed the Stimulation for Optimizing Perinatal Stroke Optimizing Recovery Trajectories (SPORT) Trial, data from 49 participants was used in this study. Trial participants (6-18 years) attended a two-week day-camp which included intensive individual motor therapy as well as were randomized to receive either active cathodal or sham tDCS. Motor function assessments and neuroimaging using MRI, including MRS, was completed at baseline, post-intervention, and 6-months following intervention. At baseline and post-intervention, GABA between hemispheres were different (p<0.001; p=0.044 respectively), and at the 6-month follow-up GABA was not different. Motor function significantly increased following the camp (p<0.001), however there was no correlation of GABA to the objective measures of motor function. There was no observed effect of tDCS on GABA over time. This project contributes to an understanding of GABA levels and other brain metabolites in children with perinatal stroke at baseline and following intensive motor therapy and tDCS interventions. Our results support the use of motor therapy for improving motor function in children with PS, however the potential effects of tDCS intervention warrant further investigation.
Mobilizing Female Entrepreneurship Research to Inform Policy

Subjects: subject: entreprenuership
subject: policy

subject: Business Administration--Management

description: Gender and entrepreneurship scholars are increasingly called upon to consider policy implications in both identifying research questions and analyzing research results. Similarly, policy professionals are looking to inform policy with best available evidence. Yet, gaps between policy and gender and entrepreneurship scholars remain in both the availability of policy relevant academic research and the applied use of such research within policy domains. This dissertation represents an attempt to fill at least part of this gap by three diverse methods as represented in chapters two through four. Chapter two leverages qualitative methodology to a real-time policy problem and explores how women entrepreneurs experienced the impact of the COVID-19 pandemic to inform the development of specific policy supports. Chapter three leverages an application of the public organization management science approach to identify policy relevant research questions for gender and entrepreneurship scholars, alongside of a review of current literature. Chapter four advances a particular policy relevant research question of special relevance within the current Canadian context, the impact of institutional support, subnational variation and providing unpaid care on the choice to become an entrepreneur. Collectively, these papers aim to advance theory, policy, and practice in helping to close the gap between the academy and policy professionals. The main limitation of this thesis is scope, as the setting both academically and for policy is limited to Alberta. Despite this, the findings of from this thesis can be broadly applied to both theory and practice. Contributions include an increased recognition of who policymakers are and what they are looking for alongside of an extension to the institutional theory of gender inequality of entrepreneurial entry. Future research can further explore policy-relevant research questions such as implications of subnational variations in institutional context on entrepreneurship.

Transitional Care for Type 1 Diabetes: The Certified Diabetes Educator Perspective
Creators: name: Rossiter, Brittany
Publisher: name: Graduate Studies

Subjects: subject: Nursing
subject: FOS: Health sciences

description: Adolescence is a time when significant growth and development occur. Undergoing typical developmental transitions may include experiences such as academic pursuits, applying to post-secondary education, and striving for increased independence. Adolescents living with type 1 diabetes (T1D) will experience typical developmental tasks and manage an invisible life-threatening chronic disease that requires constant input and thoughtful choices in food, insulin dosing, and more. The transition of care from pediatric to adult diabetes clinics occurs during this fragile period in an adolescent’s life (Allen & Gregory, 2009; de Beaufort et al., 2010). Much research has involved adolescents undergoing transition, their families, and some healthcare provider (HCP) input. However, there is a notable lack of insight from registered nurses (RNs) working as certified diabetes educators (CDEs). RN CDEs are often highly trusted members of the diabetes team and have direct and extensive contact with patients, their families, and other HCPs. Using classic grounded theory methodology, a qualitative study was undertaken to understand the perspective of registered nurses working as certified diabetes educators on the transition of adolescents from pediatric to adult diabetes care programs. Seven CDE nurses from Calgary, Alberta were interviewed. Data analysis was completed using the constant comparative process, coding, and memo-writing. The core category and theory of Adaptation, with supporting categories of Loss, Embrace the New, and Red Tape emerged through analysis. Additionally, nurse participants discussed practical options for improving transitional care for adolescents, their families and healthcare providers in Calgary, Alberta.

Incorporating the Concept of Distance into PageRank's Notion of Teleportation
Creators: name: Bowater, David William
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Complex Networks
subject: Centrality Measures
subject: Engineering

description: Centrality measures are a valuable tool for analysing complex networks because they help us to identify the most important or central nodes in a network. One of the most popular measures of centrality is PageRank which, despite being originally introduced for ranking web pages, has found widespread use in applications far beyond the web due to its simplicity and generality. However, in many real-world networks, the notion of teleportation is counterintuitive because it implies that whatever is moving around the network will jump or 'teleport' directly from one node to any other, without considering how far apart the nodes are. Therefore, the focus of this thesis is to incorporate the concept of distance into the notion of teleportation, which is accomplished by drawing upon recent advances in non-local random walks. First, an existing PageRank-based centrality measure is extended to improve its suitability for urban street networks. Then, a general measure of PageRank centrality is proposed which can be tailored for various real-world networks and applications. To evaluate the proposed measures, experiments on a variety of real-world spatial and social networks are performed. Finally, to improve our understanding of distance-based teleportation in real-world networks, an analysis of the effect of the damping factor on the rating and ranking of nodes is provided.

description: It is shown that a nonclassicality witness, whose expectation value can be measured for all quantum states, can be constructed from every nonclassicality filter. This finding leads to a set of universal witnesses, parameterized by only three real numbers, for the detection of nonclassicality of any quantum state of a harmonic oscillator. An explicit operator expression is given for such a universal witness. The application of the witnesses is demonstrated for a nontrivial example, and its experimental measurement is briefly considered.

Investigating the survivability of an ecological, family-centered positive behaviour intervention with a family of a child with a developmental disability and problem behaviour
Creators: name: Chinn, Stephen
Publisher: name: University of British Columbia
Year: 2012

description: The purpose of this study was to replicate the work of Lucyshyn et al. (2011) and Binnendyk (2009) by investigating the survivability of an intervention based upon an ecological, family-centered positive behaviour support approach to assessment and intervention. The approach integrates child behaviour, parent-child interaction, and family activity settings into an ecological unit of analysis aimed at improving child behaviour, parent-child relationships, and promoting meaningful changes in the functioning of the family. One family of a child with autism and problem behaviour participated. Two home-based family routines were targeted for assessment and intervention. A quasi-experimental, multiple baseline design across two family routines was used to evaluate the association between implementation of the intervention and child behaviour. Results documented substantial improvements at the point of intervention in child problem behaviour and routine steps successfully completed in the two family routines. These improvements maintained up to 8 months post-intervention. Sequential analysis methods were used to examine changes in parent-child interaction across baseline and intervention conditions. Results offer robust, categorical evidence of the transformation of coercive processes of parent-child interaction into constructive processes of interaction following implementation of the intervention. Social validity and goodness-of-fit results indicated that the intervention was acceptable and contextually appropriate within the ecology of the family. A high level of parent implementation fidelity was sustained across the intervention and follow-up phases. Despite positive outcomes, meaningful improvements in family functioning were not reported. Results are discussed in terms of contributions and relationship to the literature, implications, cautions and limitations, and future research.

description: Bloodstream infections (BSI) represent a major burden on modern medicine, annually causing millions of cases worldwide with high mortality rates. Concerted efforts have been made in recent decades to improve BSI diagnostics to treat these dangerous infections more rapidly and precisely. However, these efforts have been hindered by an incomplete understanding of what factors make certain BSIs more severe than others. To address this shortcoming, this thesis applied statistical, machine learning, and epidemiological analyses to systematically investigate patient- and microbe-related traits as biomarkers of BSI clinical outcome. The analyses were facilitated by the Calgary BSI Cohort, a collection of over 35,000 BSI episodes detailing microbial genomic, proteomic, and metabolomic profiles linked to extensive patient medical records. Unsurprisingly, the results demonstrated that patient-related traits (e.g., age and comorbidity) are tightly linked to BSI clinical outcome. Patient mortality, hospital stay duration, and healthcare cost could all be predicted using patient features with areas under the receiver operating characteristic curve exceeding 0.80. Several microbe-related traits such as species classification and virulence factors were also found to be associated — albeit less strongly — with BSI patient mortality risk. Interestingly though, when patient- and microbe-related traits were combined, their predictive performance for BSI patient mortality did not surpass that of patient traits alone. Follow-up analyses revealed a compelling possible explanation: many “predictive” microbial traits may simply report the underlying characteristics of patients that tend to be infected by the pathogens carrying those traits. Taken together, the results suggest that patient-related traits are critically important as markers of BSI clinical outcome. Prompt development of formalized, patient-factor-based BSI risk stratification tools seems warranted to assist physicians in precisely identifying high-risk infections early in the clinical trajectory. In contrast, while microbial characteristics are invaluable for directing clinical therapy of BSIs, they provide little unique predictive information for BSI clinical outcome, making them unsuitable as biomarkers in the context of BSI risk stratification. Future research investigating the diagnostic relevance of the microbe should take great care to adequately correct for confounding patient dynamics.

Habitat selection by foraging northern fur seals : assessing in-situ ocean temperature and links to Oceanographic features in the Eastern Bering Sea
Creators: name: Nordstrom, Chad Andrew
Publisher: name: University of British Columbia
Year: 2012

description: Habitat characteristics and mechanisms that enable predators to successfully forage are poorly understood in open marine ecosystems. I addressed this problem in the eastern Bering Sea using animal-born data-loggers carried by lactating northern fur seals (Callorhinus ursinus) from two populations breeding in distinct oceanographic zones — a declining population on St. Paul Island on the continental shelf, and an increasing population on Bogoslof Island over the oceanic basin. The data-loggers recorded water temperatures, dive depths and animal locations throughout foraging trips that lasted as long as 17 days and extended as far as 460 km from the islands. I contrasted tag-derived ocean temperatures with concurrent shipboard measurements and found that the fur seal data revealed finer-scale hydrographic processes with less estimated error than ship-derived data, particularly in dynamic oceanographic areas. I also identified probable foraging hotspots using first-passage time analysis of at-sea locations of individual females, and linked them to fine-scale hydrographic data using habitat selection models. I found that hot spots were related to thermoclines and surface fronts (although not with water temperature), and that the relationships differed between populations and among foraging strategies. St. Paul Island fur seals that mixed epipelagic and benthic dives focused their effort in areas with deeper thermoclines that may concentrate prey closer to the ocean floor, while strictly epipelagic foragers tended to use waters with shallower thermoclines allowing prey to migrate closer to the surface. Fur seals from Bogoslof Island foraged almost exclusively over the Bering Sea basin and appeared to hunt intensively along the fine-scale fronts that surrounded the island while fur seals from St. Paul Island extended their trips off-shelf to forage in areas with similar oceanographic features. It appears that lactating females rely on fine-scale boundaries in the open ocean to effectively concentrate prey, and that the relative distribution and accessibility of these oceanographic features account for the inter-island differences in foraging patterns. Collectively, my thesis shows that wide-ranging, diving animals such as fur seals can be used to produce detailed maps of marine habitat and demonstrates the importance of fine-scale habitat characteristics to top predators foraging in dynamic oceanographic environments.

description: The blossoming of interest in colloids and nano-particles has given renewed impulse to the study of hard-body systems. In particular, hard spheres have become a real test system for theories and experiments. It is therefore necessary to study the complex dynamics of such systems in presence of a solvent; disregarding hydrodynamic interactions, the simplest model is the Langevin equation. Unfortunately, standard algorithms for the numerical integration of the Langevin equation require that interactions are slowly varying during an integration timestep. This in not the case for hard-body systems, where there is no clearcut between the correlation time of the noise and the timescale of the interactions. Starting first from a splitting of the Fokker-Plank operator associated with the Langevin dynamics, and then from an approximation of the two-body Green's function, we introduce and test two new algorithms for the simulation of the Langevin dynamics of hard-spheres.

That book is a history of the origins and workings of the mandates system of the League of Nations and its impact on the international and imperial order as a whole.  These lectures concentrate more narrowly on Britain’s involvement in the construction of that system and on its unexpected effects on British strategy and power.  The fourth lecture, on British dilemmas around the Italo-Ethiopian crisis, has not been published elsewhere; the third lecture (and to a lesser degree the first and sixth lectures) also incorporate material not found in that book.  A fully international account of all the themes discussed can be found in The Guardians.

description: Dense enough compact objects were recently shown to lead to an exponentially fast increase of the vacuum energy density for some free scalar fields properly coupled to the spacetime curvature as a consequence of a tachyonic-like instability. Once the effect is triggered, the star energy density would be overwhelmed by the vacuum energy density in a few milliseconds. This demands that eventually geometry and field evolve to a new configuration to bring the vacuum back to a stationary regime. Here, we show that the vacuum fluctuations built up during the unstable epoch lead to particle creation in the final stationary state when the tachyonic instability ceases. The amount of created particles depends mostly on the duration of the unstable epoch and final stationary configuration, which are open issues at this point. We emphasize that the particle creation coming from the tachyonic instability will occur even in the adiabatic limit, where the spacetime geometry changes arbitrarily slowly, and therefore is quite distinct from the usual particle creation due to the change in the background geometry.

In order to build a phenomenologically viable model, on top of the two moduli corresponding to the base and the K3 fibre, we demand also the existence of two additional rigid divisors: the first supporting the non-perturbative effects needed to achieve moduli stabilisation, and the second allowing the presence of chiral matter on wrapped D-branes. We clarify the topology of these rigid divisors by discussing the interplay between a diagonal structure of the Calabi-Yau volume and D-terms. Del Pezzo divisors appearing in the volume form in a completely diagonal way are natural candidates for supporting non-perturbative effects and for quiver constructions, while `non-diagonal' del Pezzo and rigid but not del Pezzo divisors are particularly interesting for model building in the geometric regime. Searching through the existing list of four dimensional reflexive lattice polytopes, we find 158 examples admitting a Calabi-Yau hypersurface which is a K3 fibration with four Kähler moduli where at least one of them is a `diagonal' del Pezzo. We work out explicitly the topological details of a few examples showing how, in the case of simplicial polytopes, all the del Pezzo divisors are `diagonal', while `non-diagonal' ones appear only in the case of non-simplicial polytopes. A companion paper will use these results in the study of moduli stabilisation for globally consistent explicit Calabi-Yau compactifications with the local presence of chirality.

description: Colloidal particles can be manipulated under an applied external field, one of which is an electric field, to transport them to their desired location. The movement of charged particles or fluids due to an applied electric field is known as electrokinetics. This has widely been used in drug delivery and electrokinetic soil remediation. This phenomenon allows for an easy way to manipulate charged particles. Previous work investigating the application of drug delivery has focused on porous mediums that is homogeneous and physiochemically different from that found in tissues. The electrokinetic and hydrodynamic transport of nanoparticles in biomimetic porous medium has not been studied extensively. In this work, we have incorporated Gelatin methacrylamide (GelMA) hydrogel in a microfluidic chip to explore the transport of silica nanoparticles through the hydrogel. To accomplish this, we studied the transport of silica nanoparticles at varying crosslinker concentration, pressure driven flow and electric field intensity. Our results indicate that by increasing the crosslinker concentration, the pore size gets smaller and the nanoparticle transport is more constrained. Increasing the flow rate increases the distance that the nanoparticles can travel while also increasing the number of aggregates formed. We also explore the transport of silica nanoparticles at varying electric field strengths. We observed that increasing the electric field strength increases the distance travelled by the nanoparticles through the hydrogel and reduces the number of aggregates formed which benefits the transport of the nanoparticle. The experimental results in this thesis open up routes for electrokinetic drug delivery through heterogeneous porous media, and allow for further investigation of the effect of electric fields and more directed drug delivery.
Spin-phonon coupling effects in transition-metal perovskites:a DFT+$U$ and hybrid-functional study

description: Spin-phonon coupling effects, as reflected in phonon frequency shifts between ferromagnetic (FM) and G-type antiferromagnetic (AFM) configurations in cubic CaMnO$_3$, SrMnO$_3$, BaMnO$_3$, LaCrO$_3$, LaFeO$_3$ and La$_2$(CrFe)O$_6$, are investigated using density-functional methods. The calculations are carried out both with a hybrid-functional (HSE) approach and with a DFT+$U$ approach using a $U$ that has been fitted to HSE calculations. The phonon frequency shifts obtained in going from the FM to the AFM spin configuration agree well with those computed directly from the more accurate HSE approach, but are obtained with much less computational effort. We find that in the $A$MnO$_3$ materials class with $A$=Ca, Sr, and Ba, this frequency shift decreases as the A cation radius increases for the $Γ$ phonons, while it increases for R-point phonons. In La$M$O$_3$ with $M$=Cr, Fe, and Cr/Fe, the phonon frequencies at $Γ$ decrease as the spin order changes from AFM to FM for LaCrO$_3$ and LaFeO$_3$, but they increase for the double perovskite La$_2$(CrFe)O$_6$. We discuss these results and the prospects for bulk and superlattice forms of these materials to be useful as multiferroics.

Discourses of life, machines, and control: How science organisations represent the Earth to the public on Instagram

description: Scientific efforts have prompted significant changes in how the average person understands, and thus interacts with, the Earth. To ensure optimum Earth-human interactions, academic and policy leaders must have a clear accounting of exactly what scientific representatives are telling the public about the Earth. Yet, what little research exists tends to prioritise specific topics–climate change in particular–and media environments–like newspapers–at the expense of representations of the whole Earth or representations via new media environments like social media. Using a Multimodal Discourse Analysis, this study produced an inventory of the ways science organisations represent the Earth to the public through their official Instagram accounts. It found that the Earth is represented through, not just written language, but visual imagery, in a wide variety of ways, like ‘Earth is the water planet’, ‘Earth is beautiful’, and ‘humans are harming the Earth’. Nearly all the representations identified, however, contribute in some way to two dominant messages. That 1) the Earth is the blue water planet upon which life flourishes because of Earth’s many mechanistic life-support systems. Thus, 2) we must use science to wisely control earth to promote and protect, especially human, life. The list of identified discourses was then compared with what the National Science Foundation outlined in 2010 as the ‘9 big ideas about the Earth all citizens should know’. The study found that the current ideas science organisations advance align with the aspirational ‘9 big ideas’ in a few ways, especially in centring life as Earth’s most important and consequential attribute. However, they differ in many more, most notably in their evaluation of Earth’s dynamism. Though science organisations may intend to present Earth’s continually changing states–like Earthquakes and extinctions–as natural, they actually represent it as primarily negative and thus regrettable. Further contributing to the imperative for humans to use science to stabilise, and thus control the Earth.

description: An almost complex structure J on a 4-manifold X may be described in terms of a rank 2 vector bundle E. A splitting of J consists of a pair of line bundles spanning E. A hypersurface M in X satisfying a nondegeneracy condition inherits a CR-structure from J and a path geometry from the splitting. Using the Cartan-Kähler theorem we show that locally every real analytic path geometry is induced by an embedding into C^2 equipped with the splitting generated by the real and imaginary part of the standard holomorphic volume form. As a corollary we obtain the well-known fact that every 3-dimensional nondegenerate real analytic CR-structure is locally induced by an embedding into C^2.
