2017 — First Generation Learners in Higher Education: Tales of Shame and PrivilegeAbstract
I am a first generation learner (FGL) in higher education (HE). A FGL is a student who is the first person in their family to attend HE. Academia presents FGLs as students who are defective. FGLs are often defined in the literature as students that lack cultural capital and fail in academia due to their personal, cultural and social deficits. The underlying and insidious message in much of the research around FGLs is that they do not belong in academia. FGLs are depicted as the square peg and the academy as the round hole. In order for FGLs to ‘fit … Read more

2012 — Co-Creating Spaces: A Narrative Inquiry into Belonging, Identity, and Curriculum Making Within Schools,Abstract
This narrative inquiry (Clandinin & Connelly, 2000) inquires into the lives of three teachers, Anne-Marie, Lucy, and me. As three co-researchers we inquired into our stories of experiences which we lived out as children and youth as we participated in art making spaces in school. Throughout our research conversations we shared artistic representations of our experiences. Each of these conversations was audio taped and highlighted tensions we experienced in schools. This unfolding sharing of our stories of experiences led Anne-Marie, Lucy, and me to create visual art pieces that represented the vital place of art making experiences and spaces as … Read more

2019 — Foamy oil viscosity measurementAbstract
The rheological studies of gas-oil dispersion are essential for understanding the foamy oil flow behaviours related to high production rates in many heavy oil reservoirs. The viscosity of gas-oil dispersion is one of the critical parameters that influence the recovery in solution gas drive process. Only a few laboratory experimental studies have been carried out to investigate the effects of live oil viscosity and foam quality on the apparent viscosity of the foamy oil during the depressurization process. As for gas-in-oil dispersion, the continuous phase is the supersaturated live oil during the depressurization process. It is essential to quantify the … Read more

2014 — A Randomized Controlled Trial of a Therapist- Assisted Internet Cognitive Behaviour Therapy Program for Women with Postpartum DepressionAbstract
Postpartum depression (PPD) impacts up to 15% of Canadian women following childbirth. The debilitating disorder not only impacts the woman, but also is related to short- and long-term consequences of her infant‘s development. A systematic review of psychological treatments for PPD demonstrated symptomatic improvements from pre- to post-treatment and superiority to control conditions (Sockol, Epperson, & Barber, 2011). Remarkably, many women suffering from PPD do not receive appropriate treatment. Internet and computer-based delivery formats are an innovative way to improve access to psychological treatment. While therapist-assisted Internet cognitive behaviour therapy (TAICBT) has proven more efficacious than a controlled waitlist condition … Read more

2018 — EEG Feature Extraction and Pattern Recognition Based on Chaotic SystemsAbstract
Nonlinear dynamical systems exhibit a wide variety of dynamic behaviour, including chaotic dynamics. Previous studies have reported the chaotic nature of EEG (Electroencephalogram) signals and various feature extraction techniques for pattern recognition. This work is an effort to investigate the complex underlying dynamics of chaotic systems and to develop a machine learning based pattern recognition and feature extraction of EEG signals for computer aided diagnosis of depression. Chaotic systems which are designed by known equations can be easily controlled and is possible to predict future values, on the other hand, EEG signals are prone to noise and the available data … Read more

2010 — The Erdős-Ko-Rado Theorem for intersecting families of permutations.Abstract
The Erdős-Ko-Rado Theorem is a fundamental result in extremal set theory. It describes the size and structure of the largest collection of subsets of size k from a set of size n having the property that any two subsets have at least t elements in common. Following the publication of the original theorem in 1961, many different proofs and extensions have appeared, culminating in the publication of the Complete Erdős-Ko-Rado Theorem by Ahlswede and Khachatrian in 1997. A number of similar results for families of permutations have appeared. These include proofs of the size and structure of the largest family … Read more

2014 — Variations on a Theorem of Erdös, Ko and RadoAbstract
The Erdös-Ko-Rado theorem, a theorem which gives the size and structure of the largest pairwise intersecting collection of k-subsets from a base set of size n, has inspired many variations on the theme of the maximum size and structure of intersecting families. Some results for intersecting set systems add additional conditions or vary the intersection requirement. For instance, Hajnal and Rothschild allow up to s mutually disjoint sets. Hilton and Milner consider the largest families that do not have an element common to all of the k-subsets. Another variation is to consider objects other than subsets. For each object, a … Read more

2023 — Cellular network KPI prediction on simulated 5G-NR V2N traffic dataset using machine learningAbstract
The arrival of 5G has brought a promise of better connectivity for users, but also a challenge for cellular networks to maintain high-quality service and energy efficiency. To optimize the network and meet user demands, a resource management system is used to allocate resources in the 5G Radio Access Network (RAN). However, manual tuning of this system is complex and time-consuming. By predicting the future behavior of Network Key Performance Indexes (KPIs) of the 5G network using Artificial Intelligence (AI) and its subfield, Machine Learning (ML), this study can automate the operations of the Resource Management system, improve resource allocation, … Read more

2013 — Comparison of the vegetation and seed banks of natural and restored wetlands In the Prairie Pothole Region, Saskatchewan.Abstract
In the early 1970s, many wetlands in the Prairie Pothole Region of Saskatchewan, Canada, were drained to increase the agricultural land base. In the early-mid 1990s, Ducks Unlimited Canada (DUC) restored many of these drained wetlands to their original spill elevations, reverting back to the natural hydrological cycles and relying on any existing seed banks to passively revegetate the basins. This study compared the vegetation communities and seed banks of “Restored” wetlands to those of “Natural” (never drained) wetlands after almost twenty years, and considered whether relict seed banks could successfully restore drained wetlands without reseeding typical wetland vegetation species. … Read more
