EF between exercisers and non-exercisers
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts (Honours) in Psychology, University of Regina. 37 p.Background: Physical activity frequency and exercise adherence influence a broad arrangement of cognitive improvements, including increases in executive functioning (EF). While various recreational activities can be employed as prospective interventions to improve EF, an abundance of exercise programs exist with limited comparisons between activities. Past literature examining the correlation between EF and exercise have identified long-distance running (LDR) and yoga as two recreational activities linked to increased executive functioning; specifically, increases in attentional control.
Purpose: Therefore, the objective of the present study is to directly compare separate modes of recreational exercise programming (Yoga, LDR, and Sedentary) and their correlations to EF (Attentional Control).
Method: A total of n = 21 participants’ (Mage = 27.36, SD = 12.98) who participated in yoga, long-distance running, general physical activity, and those who were considered sedentary, were directly compared between groups using task performance on three attentional-control tasks (Stroop, 2BACK, Wisconsin Card Sorting Task), each assessing separate dimensions of EF (cognitive inhibition, working memory, cognitive flexibility).
Results: Multiple One-way ANOVA’s coupled with Tukey post-hoc tests revealed no significant differences in the Stroop task, F(3,26) = 1.625, p = .208; Stroop task error, F(3,26) = 1.201, p = .208, 2BACK, F(3,26) = .310, p = .818; 2BACK error, F(3,26) = 1.864 p = .208, or WCST, F(3,26) = 1.197, p = .331; WCST error, F(3,26) = .336, p = .799.
Implications: Future studies using an adequate sample size are needed to appropriately judge the relationship between EF and exercise.Studentn
Effect of creatine monohydrate supplementation in aging adults with type II diabetes
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. v, 58 p.Sarcopenia generally refers to the age-related reduction in muscle strength and physical performance, with greater decreases found in aging adults with type II diabetes (T2D). Supplementing with creatine, a nitrogen-containing compound formed from reactions involving the amino acids arginine, glycine and methionine, is an intervention which have been shown to increase muscle strength, endurance and physical performance in healthy aging adults. Further, creatine supplementation has been shown to influence glucose metabolism in individuals with T2D. However, the effects of creatine supplementation in aging adults with T2D in unknown. Therefore, the purpose of this study was to examine the effects of creatine supplementation on measures of blood glucose, muscle strength, endurance and tasks of physical performance in aging adults with T2D. Using a double-blind, repeated measures design, participants were randomized to supplement with creatine monohydrate (CR: n = 4; 71 ± 7 years, 94.3 ± 13.9 kg, 165.2 ± 6.0 cm; 0.3 g·kg -1·day -1) or placebo (PLA: n = 3; 74 ± 2 years, 95.2 ± 7.3 kg, 159.3 ± 9.5cm; 0.3 g·kg -1·day -1 maltodextrin) for seven consecutive days. Prior to and following supplementation, variables measured were fasting blood glucose, muscle strength (1-repetition maximum leg press, chest press, hand-grip), muscle endurance (leg press and chest press; maximal number of repetitions performed at 50% baseline 1-repetittion maximum), and tests of physical performance (6-minute walk test, sit-to-stand chair test). Results showed that both groups experienced similar changes in all measures over time. In conclusion, in this preliminary investigation, creatine supplementation had no effect on blood glucose or measures of muscle strength, endurance and physical performance in aging adults with T2D.

Addressing the ethical problem of underdiagnosis in the post-pandemic Canadian healthcare system
No full text Proper diagnosis is essential for effective treatment, yet in Canada health conditions are commonly underdiagnosed at all levels of the health system, meaning that they go undiagnosed or are diagnosed only after a delay. Underdiagnosis leads to inadequate treatment and potentially insufficient recovery and rehabilitation, as well as costly inefficiencies, such as repeat medical visits. Moreover, disparities in underdiagnosis in which vulnerable groups, such as women and Indigenous persons, are properly diagnosed at lower rates worsen existing inequities, which threatens the overall health of the general population. As health leaders and policy-makers seek to strengthen Canada’s strained healthcare system, it will be important to address underdiagnosis and its causes, including systematic bias. Providing timely and accurate diagnoses for all patients is an essential component of delivering high quality, efficient, ethical, and cost-effective healthcare. The Canadian College of Health Leaders’ Code of Ethics offers a framework for addressing underdiagnosis equitably. Utilizing the framework, suggestions are made for actions that can be taken at all levels of the health system to reduce underdiagnosis. </jats:p
"Who did I get to be?" Racialized and gendered discourses and the shaping of Indigenous girls' subjectivities in a northern Saskatchewan high school
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Education, University of Regina. ix, 286 p.This study explores how school discourses of race and gender have shaped the subjectivities of Indigenous girls in a provincial high school in Northern Saskatchewan. Feminist poststructural theory, race critical theories, and spatial theory have been used as theoretical frames to examine how Indigenous female students have taken up racialized and gendered discourses from their high school experiences. This study also examines the relationship between discourses of race and gender and the formation of identity constellations, theorizing that socially constructed identity categories do not operate separately in the constitution of student subjectivities. Specifically, this study focuses on former students of Churchill Community High School (CCHS), a provincial school in La Ronge, Saskatchewan with a large school population of Indigenous students. Interviews were conducted with fifteen former students who identify as both Indigenous and female and who attended CCHS between 2010 and 2016.
Throughout the interviews, the participants discussed experiences with messages of race and gender that circulated in the school during their time at CCHS, reflecting upon how they had responded to those gendered and racialized school discourses. Combining the research methodologies of Foucauldian discourse analysis and feminist poststructural discourse analysis, I analyzed the interviews to further identify and explore discourses of race and gender in the participants’ discussions of their school experiences. I also examined the subject positions made available through those discourses and the ways in which the participants took up, negotiated, or resisted those discourses and subject positions. Lastly, the analysis of the interviews was tied into an examination of various texts that contained wider discourses of gender and race within the historical, social, and educational context of Northern Saskatchewan.Studentye
Intelligent prediction of parameters of electric vehicles using artificial neural networks
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Industrial Systems Engineering, University of Regina. xxxviii, 392 p.This study is laser focused on the use of artificial neural networks for the prediction of parameters of electric vehicles. The study is divided into five segments. The first segment involves the application of an artificial neural network in the prediction of parameters of pure electric vehicles for design simulation purposes. The second segment is based on the application of supervised machine learning for the prediction of fuel consumption in plug-in hybrid electric vehicles. The third segment involves the application of an inverse neural network approach for the prediction of multiple outputs for the design simulation of battery electric vehicles with the aid of supporting decision-making. The fourth segment is about the inverse function based on neural networks for predicting the parameters of the fuel economy label. The fifth part focuses on the application of inverse neural networks for predicting the parameters of a lithium-ion battery.
In the first segment, artificial neural networks were applied to the prediction of parameters of pure electric vehicles. The objective of the study is to develop a model that can predict nine indispensable design parameters of pure electric vehicles. The developed model would assist in decision-making in terms of parameter selection. The categories of vehicles used include two-seater, full-size, compact, subcompact, mid-size, SUVs (standard), and station wagons (small). The accuracy of the model is promising for the predictions of the parameters.
The second segment of the study employed supervised learning approaches to predict the fuel consumption of plug-in hybrid electric vehicles. The study also proposes adding additional parameters to the fuel economy label to make the information on it more comprehensible. The accuracy of the neural network was found to be higher than that of the multiple linear regression model.
In the third segment of this study, an artificial neural network was employed to calculate and simulate the inverse functions of battery electric vehicle parameters. Nine variables were calculated and simulated as the outputs of the inverse function model at the same time. The procedure was completed for the nine cases where each of the augmented input variables of the inverse function model was the output of the direct function model. The accuracy was 142 times higher in terms of mean square error when electrical charge consumption and virtual functions were employed as input variables into the inverse function model. The proposed model will support faster decision-making in the design simulation of battery electric vehicles due to the large number of outputs simulated at once.
The fourth aspect of the study focuses on the simulation of fuel consumption and fuel economy label parameters of plug-in hybrid electric vehicles using the inverse function approach of an artificial neural network. While fuel economy is a key factor in the design of plug-in hybrid electric vehicles, a fuel economy label can educate customers about the economic advantage of purchasing a particular car. The accuracy of the model was 29.1 times greater than that of the conventional inverse artificial neural network model. The fifth segment of the study introduces a feedforward deep inverse neural network for the prediction of parameters of the lithium-ion battery in electric vehicles. The accuracy of the proposed model was 44.43 times higher than in the traditional inverse deep neural network model.Studentye
Two-parameter super-product systems of compact Hausdorff spaces
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 Mathematics, University of Regina. iv, 56 p.The theory of C∗−algebras [1, 7,17] is incredibly rich and provides a great starting
point for exploring various types of operator algebras within the realm of Functional
Analysis. Previous papers [8, 12] have used these algebras to analyze what are called
C∗-product systems and C∗-subproduct systems, as a natural generalization of two parameter
product systems of Hilbert spaces, introduced by B. Tsirelson in [18]. The
Gelfand duality shows that commutative unital C∗-product and subproduct systems
are directly related to certain two-parameter families of compact Hausdorff spaces,
referred to in this paper as compact super-product systems. Building on this, we
define the concept of flattening and show that each compact super-product system
can be flattened through a projective limit construction. Furthermore, we are able
to define a one-parameter “multiplication” induced by this flattening, which behaves
well within the framework of a C∗-product system. Finally, we show that these
results hold when considering the appropriate measures for these spaces, as well as
the various constructions defined within them.Studentye
Trans identities in autistic and ADHD Canadian children and youth
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts (Honours) in Psychology, University of Regina. 30 p.Research suggests that transgender identities are more likely to appear in those with Autism Spectrum Disorder (ASD), and that those with Attention Deficit Hyperactivity Disorder (ADHD) are more likely to identify as transgender than neurotypicals but are less likely than those with ASD. This research is limited by the fact that recruitment for these studies happens primarily at gender clinics. Since some in the transgender community do not want to or cannot seek gender affirming care at these clinics, this method of sampling can not accurately generalize to the transgender community. The current study seeks to correct this by examining transgender identities in a Canada-wide data set of children and youth. Participants were studied to address the rates of transgender identity between those with and without a diagnosis of ASD and/or ADHD. It was found that those with one or both diagnoses were 1.5 times more likely to identify as transgender than those without. The study supported the hypothesis that trans identity is more likely to develop in those with ASD and/or ADHD. Secondary tests were done to see if age of diagnosis was a significant predictor of trans identity in both ASD and ADHD groups. The second hypothesis was also correct, though only for the ASD sample. The rates seen in the first question are lower than the level of previous research, likely due to the combination of the ASD and ADHD samples. This research should be repeated with samples that can accommodate the separation of these two groups.Studentn
Towards a Holistic Model of Care for Moral Injury: An Australian and New Zealand Investigation into the Role of Police Chaplains in Supporting Police Members following exposure to Moral Transgression
No full textPolice members can be exposed to morally transgressive events with potential for
lasting psychosocial and spiritual harm. Through interviews with police members
and police chaplains across Australia and New Zealand, this qualitative study ex-
plores the current role that police chaplains play in supporting members exposed
to morally transgressive events. The availability of chaplains across police services
and the close alignment between the support they offer, and the support sought by
police, indicates they have an important role. However, a holistic approach should
also consider organizational factors, the role of leaders, and access to evidence-
based treatment in collaboration with mental health practitioners.Open Access funding enabled and organized by CAUL and its Member Institutions. This work

The administrative process that created All Nations Healing Hospital: From policy to practice
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Canadian Plains Studies, University of Regina. xvi, 371 p.The All Nations Healing Hospital (ANHH) is a unique medical facility with integrated
health services. This facility is situated in Fort Qu’Appelle, in the Qu’Appelle Valley, on land
where Treaty 4 was signed. The region consists of many First Nations communities, rural
municipalities, as well as many lakes that attract people to the region. These features create a
large catchment area for the ANHH to serve and combine to form a unique facility built within a
unique historical context.
The ANHH consists of Traditional First Nations holistic healing services and the Western
medical models co-existing under one roof. The First Nations holistic approach to healing
focuses on the complete being: not just the body, but the spirit, mind, and emotional aspects of
the individual, along with traditional medicines and culturally-specific services. The Western
medical model largely focuses on the curative aspects of health, but only the portion of the
individual that is ill. There are numerous unique services offered within the facility; one example
is the White Raven Healing Centre, which consists of many First Nations cultural services, like a
Knowledge Keeper and Elders. A medicine room, spiritual room and sweat lodge are also
offered within this portion of the ANHH. The acute care portion offers auxiliary services; a
Midwife and Nurse Practitioners are accessible within the ANHH. A Women’s Health Centre
and a new Chronic Wellness Centre, which contain dialysis units that was developed in 2017.
This facility has received exemplary status from Accreditation Canada and many organizations
from around the world have toured the facility.
The ANHH was opened in June 2004, but no complete history leading to its opening has
previously been undertaken. The transfer of ownership and management of the Fort Qu’Appelle
Indian Hospital (FQIH) to the Tribal Council, which led to the creation of the ANHH, was
limited in its documentation and was worthy of an in-depth study to understand the issues that
needed to be overcome. One of the issues included jurisdictional barriers, since First Nations
health services largely fall under federal jurisdiction due to historical Treaty rights with the
Crown. Matters relating to First Nations self-determination have, in recent years, transformed
First Nations public policies. The issue of First Nations self-determination plays a role in
understanding how and why the ANHH was implemented.
The jurisdictional and governance issues involved in a facility such as the ANHH, which
is located on Treaty Land and is owned and administered by the File Hills Qu’Appelle Tribal
Council (FHQTC), were studied through public policy initiatives and the actors and
organizations involved. This study utilizes John Kingdon’s Policy Window and Agenda Setting
Stage combined with the Five Stages of the Policy Cycle advocated by Howlett, Ramesh, and
Perl (2009) as the theoretical context. My study is in combination of this theory with an
interpretivist methodological framework – its focus is participants in the policy-process
providing their story/memories of their role in creating the ANHH.
The goal of this study was to understand how and why such a facility came about; what
policies were involved in creating this hospital; the unique aspects of the ANHH; and, whether a
facility such as this could be emulated in other regions of Saskatchewan, other locations within
Canada, or even other areas of the world. To understand the implementation process, many of the
major players were interviewed in order to interpret the path that led to the opening of this
unique facility. From these interviews and secondary documentary sources, such as archival
documents and local newspaper articles, it can be said that the ANHH is unique.

Beyond bubble baths and wine: Broadening perspectives on self-care in female social workers in Saskatchewan
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 Social Work in Social Work, University of Regina. vi, 87 p.A basic interpretive qualitative research design was used to explore the definition and application of self-care with five female social workers in Saskatchewan. These social workers volunteered to provide information about their experience as a social worker and the potential impact of self-care in their life. Data was analyzed using thematic analysis and included analysis with a feminist lens. There were seven main themes: shifting perspectives about the meaning of self-care, communication, relationships, proactivity, workplaces, holistic self-care, and therapy/counselling. Within these themes were sub-themes used to clarify the self-care practices. Findings are discussed in relation to current research on self-care in social work with recommendations for further research, and implications for practice are included.Studentye
