All that is carried
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Fine Arts in Visual Arts, University of Regina. vi, 56 p.This paper supports my Master of Fine Arts thesis exhibition, All That Is Carried,
presented at The Fifth Parallel Gallery from November 25 to December 7, 2024.
All That Is Carried concerns ideas of home, longing, displacement, and memory. My
intention is to convey feelings of disorientation and in-betweenness caused by leaving my
family home, and home country. This exhibition addresses the complexity of my transitional
state between homes. The installation consists of unstretched, shaped, and cut fabrics painted
with images of interiors of my former home in Iran. The paintings draw from photographs I
took of my former home. A wooden suitcase filled with folded paintings accompanies the
hung paintings.
Migration is the most significant change of my life. Visiting my family home in Iran,
while living in Rome, was like stepping back in time, but into a timeline that I no longer
belonged to. I was a visitor in my parent’s house. Everything that remained behind: my
family, friends, most significantly, my feelings of home, was altered. What once felt whole
and meaningful was now distant. Yet, the existence of my parent’s house kept these feelings
of home prevalent in my life. Despite living in Rome, I carried the unsettling feeling of being
tied to a home while also separate from it. This state of suspension had me question what
home and belonging mean, especially now that my parents, too, have left that house. This
double loss felt like the centre of my world had disappeared, leaving me adrift. All That Is
Carried remembers and reimagines that house through painting—transforming it into a
tangible memory. The paintings are on a lightweight fabric, like clothes, something I can
pack and carry with me. Through the process of making, I am now at a better understanding
of what my former home provided for me. I can preserve and carry the significance of home
with me.Studentye
Supporting children and families with developmental differences through a trauma-informed and disability justice-oriented approach
No full textA Practicum Report Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Social Work, University of Regina. vii, 77 p.This practicum report summarizes and reflects my learning and experiences at the Alvin Buckwold Child Development Program (ABCDP) in Saskatoon, Saskatchewan, a clinical field practicum in partial fulfilment of a Master of Social Work degree. The purpose of this 450-hour practicum was to gain graduate-level field experience using a trauma-informed care and disability justice-oriented approach while working with children and families accessing support at the ABCDP. In addition to working as a multidisciplinary team member, I engaged in case management, provided therapy to children and caregivers, and became familiar with various programs relevant to children and families with developmental differences. The report begins with a description of the Saskatchewan Health Authority and the ABCDP, a discussion of my learning goals and outcomes, and an overview of child development and family-centred care. A literature review of trauma-informed care and disability justice follows. I then discuss how these frameworks were integrated into my clinical social work practicum, along with social work values and ethical considerations. The report concludes with a summary and reflection on the personal and professional growth I experienced because of my clinical practicum experience.Studentye
Predictors of self-guided internet-delivered cognitive behavioural therapy tailored to public safety personnel
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts (Honours) in Psychology, University of Regina. vii, 69 p.Public safety personnel (PSP) face higher rates of mental disorders compared to the general population. PSP also face many barriers to accessing mental health treatments. To support PSP mental health, PSPNET offers a transdiagnostic internet-delivered cognitive behavioural therapy (ICBT) program delivered in a self-guided format known as the Self-Guided PSP Wellbeing Course. The current study aims to improve understanding of self-guided ICBT by (a) evaluating the effectiveness of the Self-Guided PSP Wellbeing Course at reducing symptoms of GAD, MDD, and PTSD; and (b) examining outcome predictors of the Self-Guided PSP Wellbeing Course. The current study used a longitudinal single-group design with data from 285 Canadian PSP who enrolled in the Self-Guided PSP Wellbeing Course. Measures were completed at pre-treatment as well as 8- and 20-weeks post-enrollment. Paired-samples t-tests and Hedges’ g assessed clinically significant changes and effect sizes on symptoms of anxiety, depression, and posttraumatic stress. Multiple regression analyses assessed outcome predictors. The Self-Guided PSP Wellbeing Course effectively reduced symptoms of anxiety, depression, and posttraumatic stress from pre-treatment to 8-weeks post-enrollment, with small-to-moderate effect sizes. Symptom improvement remains stable at 20-week post-enrollment for symptoms of anxiety and depression. Higher pre-treatment resilience is associated with lower change scores of depression and posttraumatic stress at 8-weeks post-enrollment. Overall, the current study contributes to the growing body of research supporting the use of ICBT among Canadian PSP. With a larger sample, future research should examine whether baseline resilience predicts anxiety changes scores in self-guided ICBT
Eye love arithmetic: an inversion and associativity eye tracking study
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Science (Honours) in Psychology, University of Regina. 47 p.Arithmetic is important for developing the cognitive and problem-solving skills that are fundamental for higher levels of math. As such, it is important that individuals understand arithmetic concepts such as inversion and associativity, which can be reflected in how they solve three-term arithmetic problems. If an adult solves an inversion problem like 27 + 46 – 46 by cancelling the 46s, it suggests they understand inversion and have used an inversion shortcut. Similarly, when adults solve an associativity problem like 3 × 26 ÷ 13 by first computing 26 ÷ 13, they have used an associativity shortcut. To deconstruct why some individuals are better at using shortcuts, the current study used an eye tracker to generate heat maps and compare the visual attention of shortcut users to shortcut non-users. Participants (n =22) solved 32 three-term arithmetic problems while their eye fixations were tracked. Half of the problems were inversion, and the other half were associativity. Problems differed by operators (additive or multiplicative) and their format (conducive or non-conducive). Results support previous findings that adults are more accurate and use more shortcuts on inversion, additive, and conducive problems than associativity, multiplicative, and non-conducive problems. When comparing the eye movements of shortcut users to shortcut non-users, the heat maps indicate that participants focused on different areas. Further visual and statistical analyses are needed to compare the eye movements of shortcut users to shortcut non-users. Continuing to study the visual attention of shortcut users might explain why they perform well on these problems
Forecasting CO₂ emissions and identifying key CCUS factors for achieving net-zero targets in the North American cement, iron, and steel industries
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Applied Science in Industrial Systems Engineering, University of Regina. xiii, 127 p.Emissions of pollutants and their consequences on the atmosphere have received special attention from international organizations in recent years due to the climate crisis previewed in the next decades. In this regard, Carbon Dioxide (CO2) emissions produced in industrial sectors is one of the most concerning compounds because of its impact on global warming and climate change. International organizations have emphasized the necessity of creating a plan to gradually reduce the concentration of this pollutant in the atmosphere. This study employs multi-objective mathematical models combined with machine learning algorithms to predict CO₂ emission trends and evaluate mitigation techniques on Cement and Iron and Steel (I&S) industries. Furthermore, Carbon Capture, Utilization, and Storage (CCUS) technologies are assessed as a potential solution, utilizing Fuzzy and Rough DEMATEL analyses to identify and prioritize factors for successful CCUS deployment in industrial applications. The findings reveal a steady increase in CO₂ emissions in both cement and I&S industries, with an estimated annual growth of 0.58–0.7 MtCO₂ from 2020 to 2050. An improved accuracy in forecasting was obtained through the Generalized Reduced Gradient and Whale Optimization algorithms, achieving up to a 48.13% reduction in Mean Absolute Error. In the same way, findings reveal the prominence order and causal relationships among the main factors associated with each stage of CCUS, based on a comprehensive review of existing literature and validation from seasoned experts on the field. This study aims to provide stakeholders and decision-makers with valuable insights to facilitate the successful implementation of CCUS projects in manufacturing, thereby advancing progress toward the Net-Zero emissions targets set by environmental organizations.

Depicting variable elimination with Bayesian networks
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Science in Computer Science, University of Regina. xii, 55 p.This thesis presents a novel graphical representation of variable elimination in
discrete Bayesian networks (BNs) utilizing the BN’s directed acyclic graph (DAG)
component. This includes methods representing both multiplication and marginalization
operations.
This graphical representation is achieved by introducing what are known as compound
BN nodes, whose presence denotes a compound BN. The key to fitting them into
the pre-existing BN DAG is to re-evaluate what a single node in the DAG represents;
not a single variable, but the left-hand side of a single conditional probability table
(CPT) of the BN. Using compound BNs allows for more descriptive nodes that can
better represent the dependency relationship between variables as they are merged
and marginalized out according to the variable elimination algorithm (VE), which is
used for efficient probabilistic inference using BNs.
This thesis also presents an application which implements the graphical representation
of VE. This implementation follows the introduced d-separation algorithm to
add edges to preserve the dependencies for the elimination target’s parents, children,
and spouse nodes. Node multiplication, as it is conceptually understood, is redundant
in this implementation as it does not need to generate and modify compound
nodes; just delete classic BN nodes and their edges after adding compensatory edges
according to d-separation.
The work presented in this thesis precisely depicts the recursive elimination of
arbitrary variables as classical BNs. This new graphical representation is an improvement
over previous literature, which is currently limited to graphically representing
the probability information as a sub-DAG prior to variable elimination starting or
special cases of variable elimination. Other previous attempts in the literature would
take a non-Bayesian approach to representing arbitrary variable elimination, whereas
this graphical representation is done entirely by utilizing a BN DAG.Studentye
Participation in 12 weeks of the Saskatchewan Health Authority’s Diabetes Wellness Series: Effects on appetite hormone response to a mixed meal tolerance test
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Science in Kinesiology and Health Studies, University of Regina. x, 140 p.Food intake (FI) dysregulation in type 2 diabetes (T2D) may be due to impaired tonic satiety signals (e.g., insulin, leptin) and episodic FI signals (e.g., glucose, acyl-ghrelin [a-ghrelin; appetite-stimulating], active glucagon-like peptide-1 [aGLP-1; appetite-inhibiting]), promoting caloric overconsumption. Research has shown that regular physical activity is associated with more sensitive appetite control. The present thesis aimed to: (1) investigate the acute responsiveness of FI regulatory signals (glucose, insulin, a-ghrelin, aGLP-1) and perception of appetite to a 120-minute mixed meal tolerance test (MMTT) in individuals with T2D, and (2) assess the impact of participation in 12 weeks of the Saskatchewan Health Authority’s (SHA) Diabetes Wellness Series (DWS) program, incorporating exercise (aerobic and resistance) and education (e.g., nutrition, mental health, stress, etc.), on FI regulatory signal responsiveness and perception of appetite to an MMTT.
Data from 21 participants (9M, 12F; age = 68.0±9.8 y; duration of T2D diagnosis = 11.0±10.7 y) was collected for Objective 1; values for blood glucose (6.4±1.7, 7.5±2.2, 8.8±2.2, 9.5±2.6, 9.6±3.1, 8.4±3.0mmol/L), a-ghrelin (251.9±198.5, 189.3±147.5, 151.1±124.7, 159.1±147.7, 129.3±113.2, 213.4±193.5pg/ml), aGLP-1(1.1±1.1, 3.0±2.6, 3.4±4.0, 1.8±1.6, 1.7±2.5, 1.5±1.3 pM), insulin (19.3±9.1, 28.5±19.4, 40.7±31.9, 56.6±40.9, 47.9±33.2, 36.9±28.6 ulU/mL), and average appetite (AA; via visual analog scale) (47.7±22.2, 38.6±23.2, 38.7±19.2, 36.1±17.1, 46.4±20.0, 51.5±16.7 mm) were observed before, and at 15, 30, 60, 90, and 120-mintute after consuming a 237g Boost® (240kcal [56.4% carbohydrate, 24.9% protein, and 18.7% fat]). Repeated measures General Linear Model (GLM) analyses revealed a significant effect of time for all FI regulatory signals and perception of appetite (p<0.05). Compared to the literature on metabolically healthy adults, fasted values of a-ghrelin were low while fasted values of glucose, insulin, leptin, and aGLP-1 were high, and there was an impaired responsiveness to the MMTT. No relationship between FI regulatory signals and AA suggests a disrupted association between FI signals and perception of appetite in T2D.
Sixteen participants (7M, 9F; age = 69.0±11.0 y; duration of T2D diagnosis = 11.0±10.3 y) returned after the 12-weeks of SHA DWS programming. Factorial repeated GLM analyses assessed main effects of training state (pre vs. post) and time (0, 15, 30, 60, 90, 120 minutes) and their interactions; no interactions or main effects of training-state were found; however, a main effect of time was observed for all FI regulatory signals and perception of appetite (p<0.05). Incremental area under the curve (iAUC) analyses showed increased aGLP-1 (p=0.03) and a trend towards decreased a-ghrelin (p=0.07). The hormone ‘sensitivity’ did not change at post-intervention; however, no significant change in the relationships between FI regulatory signals and AA were observed. While 12 weeks of adherence to the SHA DWS had a positive influence on some aspects of FI regulation, it may not have been enough to elicit clinically significant changes. The DWS should continue to be promoted to expose individuals with T2D to exercise programming and education; however, extending the program duration beyond 12 weeks to allow more time for habit formation (i.e., positive lifestyle change), introducing more intensive and frequent exercise sessions, and adopting a more focused approach to nutrition and dietary changes may be necessary to enhance the effectiveness of the DWS. Further, future directions to address the high incidence and prevalence of T2D in Saskatchewan should include prevention in addition to management.Studentye
The role of modular construction and BIM technologies in sustainable construction and demolition waste management
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Applied Science in Environmental Systems Engineering, University of Regina. viii, 73 p.Construction and demolition activities significantly contribute to global waste
generation, necessitating sustainable measures. This thesis explores advanced C&DW
management through Building Information Modeling (BIM) and modular construction
techniques. In the initial phase of the study, a comprehensive text-mining analysis of 493
scholarly publications (2009-2024) reveals key themes and temporal trends. The cooccurrence
analysis identified three distinct clusters centered on C&DW management,
highlighting strong correlations between "sustainability" (Links=41), "BIM" (Links=46),
and "C&DW" (Links=46). Thematic development and evolution analysis indicated that
during the third period (2018-2021), transversal themes included Material Passport
(OCC=92) and Prefabrication (OCC=482). In the fourth period (2022-2024), transversal
themes encompassed Digital Twin (OCC=44), Waste Minimization approaches in BIM
(OCC=64), and Decision-Making Systems (OCC=64). Strategic diagrams and Temporal
evolution mapping generated by SciMAT software illustrate the progressive integration of
BIM tools like digital twins, Material Passport, Prefabrication, and Decision-Making
System, offering avenues to optimize waste reduction. The subsequent part of the study
explores modular construction techniques for their potential to mitigate material waste and
enhance sustainability in building practices. Significant research interest since 2015,
coinciding with the UN Sustainable Development Goals (SDGs), is observed. Keyword
trends have sustained interest in recycling since 2014. Cluster and network analysis
highlight "Recycled Aggregate Concrete (RAC)" as a high-impact theme (confidence
100%).The importance of the mechanical properties of RAC in modular construction is
also emphasized.Studentye
