Impact of cultural adaptation in digital narrative therapy on psychological distress: a randomized controlled trial
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts (Honours) in Psychology, University of Regina. viii, 73 p.This study delves into how narrative therapy, a tool that empowers individuals to reshape their life stories, intersects with digital methods and cultural considerations to influence mental health outcomes. While we embrace digital mental health tools, cultural intricacies are frequently ignored, potentially impacting the intervention’s effectiveness. This study addresses this oversight, investigating how cultural adaptation links with intervention efficacy, and investigates whether culturally sensitive interventions lead to improved mental health outcomes, uncover unique cultural strengths, influence help-seeking decisions, and resonate more effectively with specific subgroups. Participants in this study included University of Regina students (N=130) aged at least 18 years without significant recent trauma, substance use, mania, or psychosis. A mixed-methods approach was employed, integrating quantitative analysis through paired sample t-tests, one-way analyses of variance (ANOVAs), and multiple linear regressions along with qualitative thematic analysis of responses provided as part of the intervention. Findings revealed a significant improvement in feelings of tenseness and self-confidence post-intervention. However, no significant difference in anxiety scores from pre- to post-test were identified, suggesting that the brief nature of the intervention may not have been sufficient to cause measurable changes in levels of anxiety. Additionally, no significant difference between the outcomes from the culturally adapted and non-culturally adapted groups were found, which implies that mental health professionals can provide their patients with the option to choose between either type of intervention, advocating for a more inclusive and effective mental health treatment landscape

No full textAuthor's accepted version (postprint).
This is an Accepted Manuscript of an article published by Emerald Publishing Limited in International Journal of Educational Management on 9 January 2024. The article was accepted for publication on 13-Dec-2023.
Available online: https://www.emerald.com/insight/content/doi/10.1108/IJEM-07-2022-0249/full/htmlPurpose: This paper explores who, amongst the AACSB categorization of academics, conducts
scholarship of teaching and learning (SoTL) research within business schools and how AACSB accredited business schools capture SoTL research as part of their portfolio of intellectual contributions.
Design/methodology/approach: This study adopts a qualitative-method research design by
collecting primary data through surveys, semi-structured interviews, and secondary data in policy
documents focused on AACSB-accredited business schools in Canada and the United States.
Findings: The findings establish that scholarly and practice academics who possess rigorously
acquired research skills due to their terminal degrees are most likely to conduct SoTL research. The results also reveal an even split among respondents regarding whether their AACSB accredited business school captures SoTL with their journal ranking frameworks.
Practical Implications: Based on the findings, two recommendations are offered to foster more
SoTL research at AACSB-accredited schools. First, higher education leaders (e.g., business school
deans) can further inculcate a culture of SoTL research at the department and institutional levels
by creating communities of practice (CoP). Second, AACSB-accredited business schools could
adopt more inclusive journal ranking frameworks to capture better and incentivize SoTL research.
Originality/value: This is the first known study to explore how AACSB Standards 3 and 8 are
implemented and operationalised regarding SoTL research. Understanding how these Standards
are adopted and implemented could help institutional leaders, standard setters, and administrators
better facilitate SoTL research
Women in social work leadership in Saskatchewan: The myth of shattering the glass ceiling
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, University of Regina. xii, 132 p.The purpose of this qualitative research was to enhance knowledge about the experiences
of women in the 1% of marginalized leadership representation statistics in Saskatchewan in the
field of social work. Through an intersectional feminist framework, based on the interrelatedness
of our social identities, both privileged and oppressed; narrative interviews were completed with
five women. The participants identified as belonging to the LGBTQ2S+, BIPOC, disability
and/or trans communities. Within the social work leadership sector, the women have held upper
management, director, and CEO positions. Data was analyzed through a case-by-case analysis
and a thematic analysis. Several key findings emerged from the research: Social workers in
upper management positions demonstrate a commitment to relational values in their leadership
perspectives. Women encounter micro, mezzo and macro fractures within the profession.
Women face intersecting forms of oppression, and do not relate to the metaphor of the glass
ceiling in leadership. When it comes to leadership styles, humanistic and collaborative leadership
models are embraced by social work leaders. Finally, mentorship is a profound legacy in the
momentum of creating future leaders. This thesis offers a comprehensive exploration of
leadership within the context of social work, focusing on the perspectives of marginalized
women in leadership roles in Saskatchewan. The findings highlight the significance of the
disruption of gendered leadership roles, and the multiple intersecting forms of oppression and
privilege women in leadership contend with in their everyday work. Readers are brought to
consider, through the unique and collective perspectives offered by participants, the importance
of expanding and redefining the meaning of leadership in social work.Studentye
Carbon dioxide and ethane solubility in bis tri (fluromethylsulfonyl) imide-based ionic liquids: Selectivity measurements and modelling
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 Process Systems Engineering, University of Regina. xi, 115 p.The urgent need to address carbon dioxide (CO2) emissions, a critical factor in escalating greenhouse gas levels and global warming, underscores the significance of effective capture and reduction methods. This research investigates the absorption of Carbon Dioxide and Ethane in three ionic liquids: 1-Decyl-3-MethylimidazoliumBis (Trifluromethylsulfonyl Imide) [IL1], 1-Hexadecyl-3-Methyl imidazoliumBis (Trifluromethylsulfonyl Imide) [IL2] and Triethytetradecyl Ammonium Bis (Trifluromethylsulfonyl Imide) [IL3].
Solubility measurements of CO2 were conducted from 303.15K to 343.15K and pressures up to 1.5 MPa, utilizing a gravimetric microbalance. The acquired solubility values were correlated with the Peng Robinson (PR) equation of state (EoS) using three mixing rules: Single - van Der Waals one (VDW1), Binary - van Der Waals two (VDW2), and the Wong-Sandler combined with the non-random two-liquid model (WS-NRTL).
From the experimental findings, the ILs studied in this research showed the lowest Henry's Law constant (H) i.e. higher solubility of CO2 when compared to all Ionic Liquids in the Literature and even Selexol/ Genesorb 1753, a benchmark physical solvent in Industry. It only appeared less effective than 1-octyl-3-methylimidazolium bis (trifluoromethylsulfonyl)imide, a solvent with high molecular weight and viscosity, making them promising solvents for CO2 removal.
[IL2] exhibited the lowest Henry's Law constant (H) i.e. the highest solubility among the studied ionic liquids (ILs) for CO2 absorption, The observed experimental trend wherein [IL1] and [IL3] capture relatively less CO2 than [IL2] up to 1.5 MPa at 30 ℃, 50 ℃, 60 ℃ and 70 ℃, and can be attributed to various factors inherent to the intermolecular structures and properties of these ionic liquids (ILs). Typically, the longer alkyl chains are associated with increased van der Waals interactions and higher solubility for gases like CO2. Thus, the longer alkyl chain in [IL2, 1-Hexa decyl-3-Methyl imidazolium Bis (Trifluromethyl-sulfonyl Imide)] facilitates a more effective CO2 absorption. Additionally, the larger molecular volume and increased surface area of the Hexadecyl-based IL provide more interaction sites for CO2 molecules.
Furthermore, Henry’s law constant for Ethane in [IL1] was the highest (lowest solubility) relative to the two other ILs studied. The selectivity of CO2 over C2H6 was obtained and the overall selectivity was in the following order: [IL1] > [IL3]> [IL2]. Comparing this selectivity data to published ILs revealed they are only attractive when used for CO2 capture with no ethane present as in the case of flue gases.
Furthermore, insights into the enthalpy and entropy of absorption underscored CO2 stronger interactions and higher solubility than Ethane. These results highlight the significant impact of IL structure on CO2 solubility, confirming the potential of tailored ILs for enhanced carbon capture strategies.
In summary, the best ionic liquid amongst the three studied for CO2 capture is therefore [IL2] due to its lowest Henry’s law constant towards CO2 absorption, however [IL1] would be the best ionic liquid provided C2H6 co-absorption is of crucial importance and needs not to be avoided.Studentye

No full textA mixed methods study on barriers and facilitators to exercise for suicidal ideation management
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 Clinical Psychology, University of Regina. xiii, 277 p.Suicide is a leading cause of premature death. Innovative and effective interventions are
needed to prevent suicide deaths. Randomized controlled trials (RCTs) have
demonstrated that a variety of structured exercise programs (e.g., aerobic exercise,
resistance training exercise) improve mental health, including reducing anxiety and
depressive symptoms. Moreover, failure to meet established guidelines for physical
activity is associated with increased odds of experiencing suicidal behaviours. Exercise
may, therefore, be one intervention option to reduce the suicidal behaviours (i.e., suicidal
ideation [SI] and plans for suicide) that often precede suicide. In order to benefit from the
effects of exercise, individuals with suicidal ideation must perceive exercise as an
accessible, acceptable, and effective treatment option, otherwise they are unlikely to
initiate and sustain an exercise program. This mixed-methods dissertation includes two
studies that explored how individuals with SI perceive and experience exercise, with an
emphasis on identifying facilitators and barriers to exercise. In Study 1, grounded theory
methods were used to analyze data from semi-structured interviews with 17 adult
Canadian participants with past-month SI. The overall theory derived from Study 1
suggests that exercise for individuals with SI is complex and should be tailored to each
individual. This theory is made up of a core category of individualization, as well as four
key concepts that relate to three major categories. The four key concepts of the theory are
that facilitators and barriers to exercise (a) have individualized weights/impacts on
exercise decisions, (b) are cumulative, interactive, and opposing forces, (c) are dynamic,
and (d) exist on a spectrum from internal to external. The three major categories included
in the study theory are (a) the cognitive-behavioural cycle, (b) priorities, values, and
identity, and (c) interpersonal factors. In Study 2, 261 Canadian adult participants with
past-month SI completed an online survey. The survey included measures of suicidal
behaviour, facilitators and barriers to exercise (open-ended and closed-ended questions),
past-week physical activity, and demographic and health questions. Due to the
exploratory nature of the study, quantitative analyses were restricted to descriptive
statistics. The qualitative and quantitative results of Study 2 supported and added to the
theory developed in Study 1, including offering additional evidence of the core category,
the four key concepts, and the three major categories. Most participants thought exercise
can reduce SI. Improved health, both mental and physical, was a commonly reported
motivator to exercise, and poor mental health was also a commonly reported barrier to
exercise. Overall, the results of both studies demonstrated the importance of
individualization when it comes to exercise for individuals with SI. Exercise may or may
not be an accessible, acceptable, and/or effective intervention for any given individual
with SI. The results may be used by clinicians, researchers, policy makers, and advocacy
groups considering whether exercise might be an intervention option for individuals with
SI. The results may assist future researchers who endeavor to develop exercise-based
interventions for individuals with SI by providing a theoretical framework to guide
intervention development and study planning (e.g., by highlighting the need to anticipate
and address individual and fluctuating facilitators and barriers).

Responses to hawking attack and distress call sequences by bats 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 Science in Biology, University of Regina. vi, 37 p.Eavesdropping on acoustic signals can be an important decision-making tool for many animals.
Despite how much research has gone into how bats use sound for orientation and foraging,
surprisingly little research has focused on eavesdropping as a decision making and survival tool.
I assessed how four insectivorous bats in North America, the big brown bat (Eptesicus fuscus),
hoary bat (Lasiurus cinereus), silver haired bat (Lasionycteris noctivagans), and little brown bat
(Myotis lucifugus) responded to conspecific and heterospecific call sequences. I played distress
and aerial hawking attack sequences along Battle Creek in Southwest Saskatchewan, Canada and
used acoustic detectors to determine whether there was a change in bat activity during playbacks.
Call collection and playback experiments were conducted between June – August 2022 and
2023. I expected an overall increase in activity when I played back both conspecific and
heterospecific call sequences for both call types, with some species-specific differences based on
size and life history. However, I found that M. lucifugus did not respond to conspecific or
heterospecific distress call or hawking attack sequences. This is in contrast with previous studies
that have concluded M. lucifugus is attracted to conspecific vocalizations. I also found that while
L. cinereus are attracted to conspecific hawking sequences, they are not attracted to conspecific
distress sequences. They are, however, attracted to L. noctivagans distress sequences; but,
repelled by L. noctivagans hawking attack sequences. L. noctivagans do not respond to
conspecific or heterospecific distress calls, but are repelled by L. cinereus hawking sequences.
My research highlights how little we know about how and why bats respond to call sequences
and, by extension, how little we know about bat community relationships in general.Studentye

Role of erythritol catabolism by Rhizobium johnstonii in the rhizospheres of lentil, pea, and vetch
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 Biology, University of Regina. xv, 110 p.Legumes are known for their high protein content and ability to improve soil fertility.
They form a symbiotic relationship with rhizobia through exchange of signaling molecules and
plant exudates, such as carbon sources, which, in turn, enable biological nitrogen fixation
through the formation of nodules. In the rhizosphere, the environment around the roots, bacteria
compete against each other for root colonization and nodulation.
Rhizobium johnstonii is capable of catabolizing erythritol, a known pea root exudate.
Previous deletion mutation of the catabolic genes (Yost et al., 2006) created strains unable or
with reduced ability to grow on media containing erythritol as a sole carbon source.
Subsequently, the mutant strains were impaired in their ability to compete against the wild type
to colonize pea root cells. In this study, I expanded the investigation to include lentils and vetch,
alongside pea, to assess competition between wild type and mutant strains in different legume
plants. It was determined that erythritol catabolism is important for Rhizobium for successful
colonization and nodulation of all three legume species. In this research, I demonstrate that the
capacity to catabolize erythritol is an important trait that is required across all these three plants.
Previous deletion mutations in the transporter genes resulted in strains with reduced
growth rates compared to the wild type when grown on minimal medium with erythritol as the
sole carbon source. Non-specific transporters can sometimes facilitate the uptake of similar
molecules, even if they are not the primary substrate, although their involvement in erythritol
uptake remains unclear. To further explore this, I employed an IN-seq library and TRANSIT
analysis, but these approaches did not reveal any additional specific transporters responsible for
erythritol uptake in Rhizobium johnstonii bv. viciae VF39sm mutants. The IN-Seq approach may
not be effective for identifying erythritol transporters due to the redundancy of alternative
transporter systems. Additionally, metabolic flexibility and compensatory mechanisms might
explain the observed growth on erythritol, as bacteria are able to adapt by upregulating various
transporter pathways under selective pressure.
In 2022, Mullock observed the upregulation of rhi genes (rhizosphere induced genes
involved in a quorum sensing system) in Rhizobium johnstonii bv. viciae 3841 when growing on
erythritol and compared the results with growth of this strain on mannitol, suggesting that
erythritol may act as a signaling molecule in the rhizosphere. Now the key question is whether
erythritol functions as a signaling molecule in the rhizospheres of lentil, pea, and vetch plants, in
addition to serving as a carbon source. To investigate the role of erythritol as a signaling
molecule rather than solely a carbon source, I integrated rhiA promoter-gusA fusions into wild
type, catabolic and transporter mutant strains to measure gene expression through the GUS assay.
rhiA is part of the rhiABC operon, which is involved in the quorum sensing system
of Rhizobium and plays a role in the regulation of genes associated with rhizosphere-induced
proteins. While β-glucuronidase activity was detected, it did not show consistent trends in
expression patterns across strains. Therefore, further investigation is suggested to characterize
the role of erythritol as a signaling molecule for regulation of genes not involved in erythritol
catabolism.Studentye
Analyzing distributions using a systematic programmable approach as persistent homology
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. xi, 100 p.Persistent homology is a tool in mathematics used for analyzing data topologically.
This analysis is made possible through one of its components called a filtered simplicial
complex, which is a sequence of nested simplicial complexes. With this, we can obtain
our persistent π0 (gaps) which is the number of connected components, and also apply
homology on the filtration to obtain the persistent homology.
This thesis focuses on the comparison of three fundamental probability distributions
which are the Normal distribution, Uniform distribution, and Exponential
distribution, using a Python code to derive a filtration, which we analyze to obtain
persistent homology. The comparison enables us to categorize any random data into
a distinct distribution after analyzing its behavior with the Python code.
Firstly, the three distributions are compared statistically, after which a Python
program is developed which is divided into four different sections. The first and
second sections input parameters and generate the distinct probability distribution
data respectively, while the third and fourth sections analyze the data generated from
each distribution to output relevant information which includes the persistent π0 and
the connected components. The connected components are further analyzed to form
a filtration, from which we obtain our persistent gaps and persistent homology.
In conclusion, this project provides worthwhile insights into the behavior and
characteristics of the Normal, Uniform, and Exponential distributions through the
spectacles of topology. These findings create the building blocks for analyzing and
classifying random data and also for better understanding and analyzing various
real-world phenomena governed by these distributions to enhance future research in
diverse fields.Studentye
