Unleashing Potential: Harnessing Brain-Computer Interfaces to Empower Children with Severe Physical Disabilities
Creators: name: Kelly, Dion Marie
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Neuroscience

description: Independence, inclusion, and full participation are fundamental human rights. Yet, children with significant physical disabilities like quadriplegic cerebral palsy (QCP) encounter numerous barriers to these rights. Despite their cognitive abilities, these children may struggle to communicate, interact with their environment, and participate in activities that other children take for granted. Brain-computer interfaces (BCIs) offer a potential solution. However, pediatric-focused research in BCI literature is strikingly scarce, underscoring the need for targeted research to optimize this technology for children with severe disabilities. This thesis delves into BCIs tailored for children, specifically those with severe neurological disabilities. We first explored the ability of typically developing children to control BCIs using five different mental control paradigms, refuting earlier assumptions about children's BCI capabilities, and demonstrating that they can competently control BCIs with accuracy similar to adults while highlighting the differential effects of age. We then examined the impact of gamified calibration on BCI performance, discovering that gamification doesn't benefit all children equally, highlighting the need for personalized approaches. Subsequently, we evaluated a novel Home BCI Program for children with QCP and their families, showcasing its feasibility and benefits such as enhanced convenience and social interaction, while highlighting diverse family needs. Our fourth study applied user-centered design principles to illustrate BCIs as an empowering tool for children to achieve home-based personalized goals. Lastly, we probed the feasibility of BCI-facilitated online gaming and its potential psychosocial impacts. We provided evidence that BCIs can enhance the quality of life for children with disabilities by enabling participation in simple, yet meaningful activities from which they are typically excluded. Our research deepens the understanding of pediatric BCIs and underscores their transformative potential for improving the lives of children with disabilities and their families. Moving forward, refining BCI technologies for children and emphasizing collaboration with pediatric end-users and their families is vital.

description: We consider a single molecule circuit embedded into solvent. The Born dielectric solvation model is combined with Keldysh nonequilibrium Green's functions to describe the electron transport properties of the system. Depending on the dielectric constant, the solvent induces multiple nonequilibrium steady states with corresponding hysteresis in molecular current-voltage characteristics as well as negative differential resistance. We identify the physical range of solvent and molecular parameters where the effects are present. The position of the negative differential resistance peak can be controlled by the dielectric constant of the solvent.

In-vivo 3T and ex-vivo 7T diffusion tensor imaging of prostate cancer : correlation with histology
Creators: name: Uribe Muñoz, Carlos Felipe
Publisher: name: University of British Columbia
Year: 2012

description: Diffusion Tensor Imaging has been successfully applied in prostate cancer diagnosis (Kozlowski et al., 2010). It has been well established that the water Apparent Diffusion Coefficient has a lower value in the prostate carcinomas when compared to normal prostatic tissue (Bashar, 2002; Gürses et al., 2008; Kozlowski et al., 2010; Manenti et al., 2007; Pickles et al., 2005; Sato et al., 2005; Xu et al., 2009). However, fractional anisotropy values in prostatic carcinoma have been reported to be higher (Gürses et al., 2008), lower (Manenti et al., 2007), and unchanged(Xu et al., 2009) when compared to the prostate’s normal peripheral zone. Preliminary data from a study involving diffusion tensor imaging measurements in prostate glands, in-vivo and ex-vivo following radical prostatectomy, is presented. Histology whole mount slides were registered to T2 weighted images and diffusion parametric maps using a mutual information voxel intensity registration algorithm using software developed in-house. Regions of interest which included the normal peripheral zone, the normal peripheral zone with enlarged glands, and tumours were taken into account for this study. The tumours were highlighted and graded with the Gleason score grading system by a specialized pathologist. Values of the apparent diffusion coefficient and the fractional anisotropy parameters were calculated. Monte-Carlo simulations of the behaviour of the fractional anisotropy with respect to the value of the apparent diffusion coefficient, the signal to noise ratio, and the b-value of the Stejskal-Tanner equation were performed. The results show lower values of the apparent diffusion coefficient for regions of tumours for the ex-vivo and in-vivo cases. Values of the fractional anisotropy in the prostate carcinomas are slightly higher ex-vivo than in-vivo, which may be explained by the dependence of the fractional anisotropy on partial volume effects and noise. These preliminary results show that the fractional anisotropy does not show significant differences between normal and cancerous tissue, strongly suggesting that it is not likely to contribute significantly to the diagnostic capabilities of diffusion tensor imaging in prostate cancer.

Evaluating Aerobic Exercise to Improve Symptom Burden and Quality of Life in Adults with Persistent Post-Concussive Symptoms

description: Adults who sustain a mild traumatic brain injury (mTBI) and go on to develop persistent post-concussive symptoms (PPCS) struggle to manage their symptoms and return to pre-morbid activity. There are few evidence-based treatments that have shown benefit in improving PPCS. Prescription of sub-symptom threshold aerobic exercise following mTBI has gained attention in recent years; however, the literature has largely focused on adolescents with sport-related mTBI despite the potential role of aerobic exercise in the treatment of adults with PPCS. This thesis begins by characterizing physical activity (PA) and sedentary behavior and their associations with symptom burden and quality of life (QoL) in adults with PPCS. Next, a systematic review describes the evidence for autonomic dysfunction, namely through evaluation of heart rate variability (HRV), following mTBI. Limitations of the literature including confounding variables that may influence interpretation of results are discussed. The next chapter is the protocol of a randomized clinical trial evaluating a sub-symptom threshold aerobic exercise intervention for improvement in symptom burden, QoL, specific symptom outcomes and sleep. In the following chapter, the results of the trial are presented. The thesis goes on to evaluate changes in heart rate, HRV, blood pressure and cardiac baroreceptor sensitivity between adults with PPCS and age/sex-matched controls. In the PPCS group, longitudinal changes in autonomic metrics following an aerobic exercise intervention are also presented. This work builds on our knowledge of PA and sedentary behavior in adults with PPCS and how aerobic exercise may play a role in the treatment of this patient population. Significant improvements in symptom burden, QoL and other specific symptom outcomes were observed following 6-weeks of aerobic exercise. These outcomes did not significantly improve following 6-weeks of stretching. Lower resting HRV in adults with PPCS compared to age/sex-matched controls and blunted response to postural change provides evidence of cardiovascular autonomic dysfunction in this cohort, although improvement in these outcomes was not observed with the exercise intervention. This thesis provides data to suggest adults with PPCS can benefit from sub-symptom threshold exercise and prescription of aerobic exercise should be considered in the chronic phase of injury despite persistence of symptoms.

description: This manuscript-based dissertation was prompted by first and second-year university students' challenges in learning chemistry due to the traditional focus of chemistry labs on recalling information rather than applying critical thinking. The three manuscripts (Chapters 2 to 4) in this dissertation explore the possibility of supporting students’ meaningful learning through the integration of Community Service Learning (CSL) and Reflection in the Analytical Chemistry II lab. This multi-year project analyzes three different cohorts of students. Chapter 2 (Manuscript 1) focuses on the CSL design intervention and students’ attitudes toward the service learning activity. Post-instructional surveys were completed, and the data was analyzed using a mixed methodological approach. All learners self-reported favourable engagement, attitudes, and higher self-confidence after the CSL activity. Chapter 3 (Manuscript 2) builds on the previous chapter by exploring how intentional reflection enhances students’ conscious awareness of their learning. A series of reflective essays were assigned at the beginning, during, and after the CSL activity. Reflective essays, focus group interviews, and student observations were collected from fourteen students using a case study methodology. Students articulated their learning progression across three phases: (a) connection with and contribution to the world, (b) identification of areas that are missing and development of reasoning abilities, and (c) integration in learning. Students reported liking the reflective essays because they enhanced their abilities to develop self-competency in learning. Chapter 4 (Manuscript 3) further extends this research by exploring students' attitudes toward a range of different reflective strategies. Content analysis was selected as both methodology and method to analyze the data from reflective writings, reflective discussions, and scrapbook reflections. The combination of reflective exercises supported students in recognizing the interconnections between the ideas they were learning. In addition, the step-by-step process of teaching reflection increased students’ comfort level and willingness to learn Chemistry. Chapter 5 concludes that the integration of CSL and Reflection can serve an important role in students’ academic enhancement, personal growth, and civic engagement while supporting practical skills and intellectual stimulation in the laboratory.

description: The Gross-Pitaevskii (GP) equation is a long-wavelength approach widely used to describe the dilute Bose-Einstein condensates (BEC). However, in many physical situations, such as higher densities, this approximation unlikely suffices hence one might need models which would account for long-range correlations and multi-body interactions. We show that the Bose liquid described by the logarithmic wave equation has a number of drastic differences from the GP one. It possesses the self-sustainability property: while the free GP condensate tends to spill all over the available volume the logarithmic one tends to form a Gaussian-type droplet - even in the absence of an external trapping potential. The quasi-particle modes of the logarithmic BEC are shown to acquire a finite size despite the bare particles being assumed point-like, i.e., the spatial extent emerges here as a result of quantum many-body correlations. Finally, we study the elementary excitations and demonstrate that the background density changes the topological structure of their momentum space which, in turn, affects their dispersion relations. Depending on the density the latter can be of the massive relativistic, massless relativistic, tachyonic and quaternionic type.

Gringo love : affect, power, and mobility in sex tourism, Northeast Brazil
Creators: name: Carrier-Moisan, Marie-Eve
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation is a feminist ethnography of global sex tourism in Ponta Negra, a tourist area in the coastal city of Natal, Northeast of Brazil that has become the site of important forms of mobilization against sex tourism. It critically examines the ambiguous relationships of love and money between (white) western male tourists and (mixed-race or black) Brazilian women. The methods for the project (conducted 2007-2008) focused on in-depth interviews with Brazilian women, European men, and various stakeholders such as business owners, residents, Non-governmental organization (NGO) workers, feminist activists and state agents; the author also conducted participant-observation in bars and at beaches. She theoretically situates these global ‘sex tourism’ relationships within contemporary political economic structures, historical processes of inequality in Brazil, gendered patterns of mobility and affect, as well as sites of global desire. A major theme in this thesis concerns the politics of the rescue industry as articulated by Brazilian NGOs and through campaigns against sex tourism, which typically locate the problem of sex tourism in the individual (i.e. women as victims; foreign men as deviants). This approach fails to address the complex structural inequalities and global forces that shape the lives of these women, and negates several important aspects of Brazilian women’s and foreign men’s experiences. This research shows that both are invested in ambiguous intimacies that blur affect and interest in complex ways. The main argument in this thesis is that Brazilian women in Natal capitalize on the ambiguities of sex tourism and put their femininity to work in order to establish long-term, legitimate ties with foreigners in the hope of migrating to Europe and marrying up, something they find hard to imagine, much less experience, in Brazil. The appeal for foreigners further reveals a profound sense of dissatisfaction with their social locations. Thus, love with foreigners acts as both an escape and a catalyst to remake themselves as modern subjects in projects of mobility, whether social, spatial or economic.

description: We report the observation in the GeV band of the blazar 1ES 0229+200, which over recent years has become one the primary sources used to put constraints on the Extragalactic Background Light (EBL) and Extragalactic Magnetic Field (EGMF). We derive constraints on both the EBL and EGMF from the combined Fermi-HESS data set taking into account the direct and cascade components of the source spectrum. We show that the limit on the EBL depends on the EGMF strength and vice versa. In particular, an EBL density twice as high as that derived by Franceschini et al. (2008) is allowed if the EGMF is strong enough. On the other hand, an EGMF strength as low as 6x10^-18 G is allowed if the EBL density is at the level of the lower bound from the direct source counts. We present the combined EBL and EGMF limits on as an exclusion plot in two dimensional parameter space: EGMF strength vs. EBL density.

Pandemic Precipitousness: The Predictive Validity of The Duolingo English Test for Student Success

description: Before the COVID-19 pandemic, the Duolingo English Test (DET) was not widely known, and few universities were accepting DET test scores as proof of English language proficiency (ELP) for student admission. Whereas IELTS, TOEFL, and PTE tests have been considered standardized tests based on empirical evidence against academic success in an English-speaking postsecondary environment, the predictive validity of the DET is less researched. Based on this novel situation, this present study compares the measures of ELP for academic achievement and investigates the predictive validity of the DET. This study uses the Assessment Use Argument (AUA) as its theoretical framework, and with a quantitative approach, analyses the correlation between DET scores and student academic performance utilizing Pearson’s correlation coefficient at a large Western Canadian research-intensive university. As with many other measures undertaken during the pandemic, the DET’s adoption occurred with little, if any, consultation with stakeholders most impacted by the decision. Nevertheless, an analysis of students who demonstrated ELP by using the DET for admission (n = 75) was shown to achieve higher Grade Point Averages (GPAs) than those students who demonstrated ELP by IELTS or TOEFL. The correlation between a higher GPA and admission via the DET was seen to be moderate, but statistically significant. The weak predictive ability of IELTS and TOEFL as indicators of student academic performance in this present research confirms the findings of most previous findings. While wider conclusions need to be drawn cautiously given the relatively smaller number of students admitted using DET (n = 75) compared with IELTS (n = 1161) and TOEFL (n = 212), the findings of this limited study may raise questions about the time, cost and inconvenience of more widely known international language tests, given their weak predictive ability of GPA, compared with the relative ease of the DET and its better predictive ability. Additional research is recommended on larger datasets of students demonstrating ELP via the DET, in order to further confirm the findings of this present study.

description: The ability to reliably maximize tire force usage would improve the safety of autonomous vehicles, especially in challenging edge cases. However, vehicle control near the limits of handling has many challenges, including robustly contending with tire force saturation, balancing model fidelity and computational efficiency, and coordinating inputs with the lower level chassis control system. This work studies Nonlinear Model Predictive Control for limit handling, specifically adapting to changing tire-road conditions and maximally allocating tire force utilization. We present a novel hierarchical framework that combines a single-track model with longitudinal weight transfer dynamics in the predictive control layer, with lateral brake distribution occurring at the chassis control layer. This vehicle model is simultaneously used in an Unscented Kalman Filter for online friction estimation. Comparative experiments on a full-scale vehicle operating on a race track at up to 95% of maximum tire force usage demonstrate the overall practical effectiveness of this approach.

description: Understanding the impact of space travel on the brain has become increasingly important as the space industry plans to send humans to Mars within the next decade. Magnetic Resonance Imaging (MRI) research has indicated significant and inconsistent structural changes in the brains of astronauts as a result of spaceflight. Volumetric brain changes in astronauts have the potential to cause significant and even life-threatening consequences. Recently, research has demonstrated that reports of these volumetric changes may be corrupted by the upward shift of the brain within the skull and a redistribution of cerebrospinal fluid (CSF) resulting from microgravity. This CSF shift may create errors in the classification of the dura mater from other various tissue types, producing erroneous claims of volumetric neuroplastic brain changes resulting from spaceflight. This research was developed with the aim of reducing these classification errors through the investigation of a variety of newer MRI scans and protocols that may better account for a physical displacement of the brain and CSF in the skull. Manual tissue segmentation was performed on the standard modality to provide a comparison measure. Automated tissue segmentation was performed in each modality. Dice coefficients were calculated, and a repeated measures factorial analysis of variance was performed, followed by paired-samples t-tests. Total grey matter volume measures were obtained, and a repeated-factorial analysis of variance as well as follow up comparisons were performed for this measure as well. The primary hypothesis for this work was not confirmed, as no certain modality consistently outperformed MPRAGE across all automated software. This research may help inform modality selection for astronauts, as well as caution reporting or interpreting neuroplastic brain changes in astronauts using standard methodology.

description: The annulus fibrosus in patients with degenerative disc disease (degen) and adult spinal deformities, including degenerative spondylolisthesis (dSpondy), isthmic spondylolisthesis (iSpondy), degenerative scoliosis (dScoli), and adolescent idiopathic scoliosis (AIS), often exhibit severely degenerated discs at the time of surgery. These conditions are accompanied by mechanical and structural changes in the annulus fibrosus, which can cause significant pain and affect mobility. In many cases, the patients require surgical intervention. The overarching hypothesis was that surgical patients have mechanical and structural integrity of the annulus fibrosus compared to normal patients. The objective of the study was to quantify the interlamellar mechanics, circumferential tensile mechanics, and collagen damage in samples from these patients. Interlamellar mechanical properties (Peel Stiffness, Peel Strength, and Peel Toughness) were decreased in the surgical patients compared to the normal patients suggesting a loss of integrity of the collagenous interlamellar matrix in surgical patients. Moderate to strong positive correlations between interlamellar properties and Pfirrmann Grade were observed. Circumferential tensile properties (Rate of Change of Tangential Modulus, Linear Elastic Modulus, Yield Stress, and Ultimate Tensile Stress) were decreased in the surgical patients compared to the normal patients suggesting a loss of collagen's mechanical integrity in the circumferential direction. The collagen hybridizing peptide indicated greater average mean fluorescence intensity and average percent positive ROI area in the surgical patients compared to the normal patients suggesting a loss of structural integrity of collagen. In conclusion, the present study demonstrated that compared to normal patients, surgical patients experienced a greater loss of collagen's structural and mechanical integrity in the annulus fibrosus at molecular and tissue scales.

description: This project examines selected poems written by Chinese Australian-Hong Kong poet Louise Ho, and Chinese Canadian poet Rita Wong. The point of convergence in the works of these poets is that both Ho and Wong are the prodigies of an East-West cultural clash. The works of Ho and Wong represent a cross-cultural, cross-continental diasporic experience that is shared by the Hong Kong population, as well as second-third generation immigrants of Canada. The identity crisis faced by the Hong Kong community is one that is often overlooked by postcolonial scholarships. After a 100-year colonial governance under British rule and a forceful turnover to the Chinese P.R.C. government in 1997, the identity crisis in postcolonial and post-handover Hong Kong is an existential agony in which the Hong Kong community is doubly entrapped, not merely in the dual nationality of British and Chinese, but also in an internal division within the culture itself as claims to narrative authority and cultural authenticity are central to the power dynamics between Hong Kong and Mainland China. Similarly, the existential agony faced by the second-third generation descendants of Chinese immigrants in Canada is one that delves in the uncertain space between the dominant white, Anglo-Saxon culture and the native home culture. North American cultural critics of Asian descent like Shu-Mei Shih, Rey Chow, Rita Wong, and Roy Miki, have all expressed concerns over the preservation (or lack thereof) of Asian cultural and language heritage in the predominately white literary space. The proximity between the Hong Kong population and second-third generation Chinese immigrants is that they are minority communities that struggle with preserving a culture-in-disappearance. In this light, my project intends to explore the following queries: How do these Chinese Canadian, Chinese Australian-Hong Kong poets carve out a space for identity validation and self-expression in the Anglo-Saxon poetic space? How do poets like Louise Ho and Rita Wong – themselves the prodigies of an East-West cultural clash – reconcile between their multifaceted identities? How do Ho and Wong reaffirm their self-identification through poetry?

« Résistante de l’intérieur » : Portées critique et politique des écrits de Marie Guyart de l’Incarnation (1599-1672)

description: Cette thèse s’inscrit dans la mouvance des travaux qui visent à renouveler l’importance de l’histoire littéraire de Marie de l’Incarnation, non pas uniquement comme religieuse missionnaire mais également comme femme politiquement engagée et féministe avant l’heure. Elle met en valeur la représentation de l’ethos de la femme religieuse comme stratégie discursive dans la Correspondance ainsi que la Relation de 1633 et celle de 1654, et a pour objectif de montrer comment la construction de l’image de soi institutionnellement codifiée (telle que façonnée par le milieu social, culturel et religieux du XVIIe siècle) est une forme d’obéissance, mais aussi, paradoxalement, une stratégie de résistance individuelle. Par l’adaptation du concept du paradoxe genré que Daniella Kostroun applique aux religieuses jansénistes de Port-Royal, cette étude permet de comprendre le discours de Marie de l’Incarnation telle la médiation d’une parole de femme « subalterne » qui confronte de manière implicite la condition des religieuses du XVIIe siècle, en fonction des rôles genrés qui les maintiennent dans un état de subordination par rapport aux hommes. Privilégier une lecture moderne et féministe des écrits de Marie de l’Incarnation élargit notre compréhension des femmes religieuses de l’époque moderne en montrant la continuité dans les stratégies discursives employées par les femmes, et témoigne d’une politisation progressive des usages et des pratiques d’écriture chez les religieuses. En pleine époque classique, laquelle voit s’affirmer un premier mouvement féministe lié aux salonnières et aux précieuses, Marie de l’Incarnation s’impose au sein d’un féminisme décolonial qui s’étendra alors au-delà des arts et des lettres au XVIIe siècle, pour enfin prendre position au cœur de l’Église de la Contre-Réforme, en France et dans ses colonies. C’est pourquoi cette thèse joint la notion de l’image de soi, empruntée à l’analyse du discours de Maingueneau et Amossy, et la théorie agentiviste de Barbara Havercroft pour évaluer dans quelle mesure les textes de Marie de l’Incarnation sont une lumière nouvelle sur la représentation des femmes dans le discours culturel moderne, tout en restant fidèle aux contraintes et aux possibles de son temps.
Optimal stability polynomials for numerical integration of initial value problems

description: We consider the problem of finding optimally stable polynomial approximations to the exponential for application to one-step integration of initial value ordinary and partial differential equations. The objective is to find the largest stable step size and corresponding method for a given problem when the spectrum of the initial value problem is known. The problem is expressed in terms of a general least deviation feasibility problem. Its solution is obtained by a new fast, accurate, and robust algorithm based on convex optimization techniques. Global convergence of the algorithm is proven in the case that the order of approximation is one and in the case that the spectrum encloses a starlike region. Examples demonstrate the effectiveness of the proposed algorithm even when these conditions are not satisfied.
An Evaluation of an Online Learning Module to Increase the Confidence and Self-Efficacy of Canadian Healthcare Trainees in Vaccine Communication, Advocacy, and Promotion.

description: Introduction: Vaccine hesitancy is a significant threat to public health. Healthcare providers (HCPs) are well positioned to address vaccine hesitancy, however there are few accessible and multidisciplinary educational tools available to teach HCPs how to engage in challenging vaccine conversations. Based on this need, virtual simulation games (VSGs) were developed to improve the confidence and self-efficacy of HCP learners to prepare them for future roles in vaccine advocacy, delivery, and promotion. The objectives of this thesis were to 1) evaluate the impact of the VSGs on HCP learners’ confidence and self-efficacy; and 2) explore HCP learners’ previous experiences and qualitatively evaluate the VSGs prior to dissemination. Methods: This study, which utilized a pragmatic sequential embedded mixed-methods design, involved quantitative evaluation of the effectiveness of the VSGs through a pre-post study with 72 HCP learners, followed by qualitative focus groups with a subset of 22 participants. HCP learners in nursing (n=24), pharmacy (n=30), and medicine (n=18) were included from the University of Calgary and the University of Waterloo. Three key themes were identified through pragmatic thematic analysis. Results: No significant differences in baseline confidence and self-efficacy were identified across the three HCP disciplines. Only 54.2% of participants reported previously learning about vaccine communication in their programs. The VSGs significantly improved these attributes in all disciplines (P<0.001). During focus groups, participants expressed 1) their previous education lacked training on holding vaccine conversations, resulting in uncomfortable experiences; 2) the VSGs increased their confidence by providing novel tools and skills; and 3) participants provided feedback to improve the VSGs. Conclusions: This study supports the use of the VSGs as an effective educational tool as HCP learners showed significant improvement in their self-assessed confidence, self-efficacy, and willingness to engage in vaccine conversations. In particular, the VSGs introduced innovative strategies for HCP to initiate these conversations, and participants appreciated the emphasis on resilience and managing emotions. In combination with existing immunization training, these and future VSGs can be designed and implemented to allow HCP to address vaccine hesitancy more effectively to increase vaccine confidence and uptake.

description: We study the nuclear enhancement of the transverse momentum imbalance for back-to-back particle production in both p+A and e+A collisions. Specifically, we present results for photon+jet and photon+hadron production in p+A collisions, di-jet and di-hadron production in e+A collisions, and heavy-quark and heavy-meson pair production in both p+A and e+A collisions. We evaluate the effect of both initial-state and final-state multiple scattering, which determine the strength of the nuclear-induced transverse momentum imbalance in these processes. We give theoretical predictions for the experimentally relevant kinematic regions in d+Au collisions at RHIC, p+Pb collisions at LHC and e+A collisions at the future EIC and LHeC.
