2025 — Alliances, assemblages, and affect: Teacher activism within and beyond the union in SaskatchewanRésumé
In recent decades, Canadian governments have increasingly drawn upon global neoliberal policies to regulate the work of teachers and their professional organizations (Bascia, 2015; Smaller, 1998). Neoliberalism has radically altered educational policies with respect to curriculum, teaching pedagogy, and teachers’ professionalism (Apple, 2006; Ball, 2003), impeding teachers’ ability to deliver democratic education (Darder, 2019). Viewing teacher activism broadly, this research explored Saskatchewan teacher activists’ resistance to marketdriven educational reforms through their engagement with both the power of grassroots social movements and the institutional authority of their union. Guided by Harding et al.’s (2018) poststructural framework of alliances, assemblages, and affects, … Lire la suite

2025 — Developing photoresponsive lipid nanoparticles for the triggered release of small moleculesRésumé
This thesis will examine numerous photo responsive drug delivery nanoparticles containing two different first-generation (1G) donor-acceptor Stenhouse adduct (DASA) molecules, DOPC, DLPC, cholesterol and lauric acid. The DASA isomerizes upon visible light irradiation, thereby increasing membrane permeability through disruption of the bilayer and releasing cargo. A 1G dioctyl DASA and a new 1G cholesterol-DASA conjugate were synthesized, and their photophysical properties were studied and compared. The dioctyl DASA was studied in DLPC with and without lauric acid, as it was observed that the lauric acid promotes thermal isomerization of the photochrome, eliminating photocontrol of the system. Thus, the incorporation of … Lire la suite

2025 — Learning hypertrees with shortest path queriesRésumé
One branch of computational learning theory focuses on algorithms for learning discrete structured objects from queries. In this context, we consider the problem of learning a labeled hypergraph from a given family of hypergraphs using shortest path (SP) queries. An SP query specifies two vertices and asks for their distance in the target hypergraph. For various classes H of hypertrees, we present bounds on the number of queries required to learn an unknown hypertree from H. Matching upper and lower asymptotic bounds are presented for learning hyperpaths and hyperstars. Moreover, inspired by Hein’s algorithm for learning evolutionary trees with bounded … Lire la suite

2025 — Towards root cause analysis in hybrid dynamic domainsRésumé
Reasoning about actual causes of observed effects is fundamental to the study of rationality. As such, this important problem has been studied since the time of Aristotle, with formal mathematical accounts emerging recently. We live in a world where change due to actions can be both discrete and continuous, i.e., hybrid. Yet, while there has been extensive research on actual primary and indirect causes in discrete dynamic domains, only few recent studies address causation in such hybrid domains. Building on recent progress, in this thesis I propose a first definition of primary cause in a hybrid temporal action-theoretic framework. My … Lire la suite

2025 — New probabilistic approaches for detecting and evaluating concept drift in data streamsRésumé
In modern applications like online shopping, financial forecasting, and real-time fraud detection, data distributions frequently shift, causing predictive models trained on historical data to underperform. This phenomenon, known as Concept Drift (CD), presents a major challenge in adaptive learning environments, necessitating ongoing monitoring and adjustment to accommodate evolving data streams. Active drift detection methods, which track changes in data distribution or model performance, offer a targeted solution by prompting adaptations only when significant shifts are detected. However, existing active methods face challenges: distribution-based approaches may miss subtle drifts or respond to non-critical changes (virtual drift), while performance-based methods, which detect … Lire la suite

2025 — Neurophysiological mechanisms of dual-tasking in people with multiple sclerosisRésumé
Saskatchewan has one of the highest rates of multiple sclerosis (MS) globally, affecting approximately 4,000 people within the province. An emerging topic of study within MS rehabilitation is dual-tasking (i.e., the performance of two tasks simultaneously). Reports on dual-task performance among people with MS (PwMS) vary in the literature, with past research limited by methodological differences and minimal consideration of the underlying neurophysiology. Studies suggest that changes in inhibitory neural activity in the motor cortex may support dual-task performance in healthy adults, as assessed by transcranial magnetic stimulation (TMS) techniques. Other TMS work indicates that MS alters corticospinal inhibition, but … Lire la suite

2025 — Proportional hazards modelling for current lifetime dataRésumé
Current lifetime data represent a unique subset of length-biased data where only the times from the initiating event to the cross-section date are observed without follow-up. We propose an efficient estimation procedure to fit the semi-parametric proportional hazards model using current lifetime data. This estimation procedure is based on the EM algorithm which has two versions based on the support points of the non-parametric baseline hazard function. We apply the method to simulated data and Parkinson’s disease current lifetime data drawn from the Canadian-Open Parkinson Network (C-OPN). We estimate the effects of clinical and epidemiological covariates using the proportional hazards … Lire la suite
