From Cuffs To Compassion: The Impact Of Relational Policing De-Escalation Approaches On Public Perceptions Of Safety, Satisfaction, Procedural Justice, And Police Legitimacy., Brook Snider

Theses and Dissertations (Comprehensive)

Academics, policy makers, and the public have called for the prioritization of de- escalation training and use in public-police interactions to reduce police use of force (PUoF) (e.g., Dubé, 2016; Iacobucci, 2014; Todak, 2017; Wortley et al., 2021). In response to various calls to action, the Ministry of the Solicitor General launched the Ontario Public-Police Interactions Training Aid Framework in 2023, which emphasizes the importance of utilizing a relational policing approach in public-police interactions (see Lavoie et al., 2022). However, despite changes in police training frameworks, relatively little is known about PUoF in Canada (Wortley et al., 2021), with similarly …

Impact Of Membrane Lipid Composition On The Structure And Function Of Uncoupling Proteins 1 And 2 From Arabidopsis Thaliana (Atucp1 And Atucp2), Elizabeth Silva

Theses and Dissertations (Comprehensive)

A proton gradient across the inner mitochondrial membrane (IMM) is required for the synthesis of adenosine triphosphate (ATP) via ATP synthase. In other words, generation of the proton gradient is coupled to the synthesis of ATP. Interestingly, uncoupling proteins (UCPs), also located in the IMM, dissipate the proton gradient, meaning that the gradient is not efficiently used for the production of ATP.¹ The mechanism of proton transport activity of UCPs has been hypothesized and widely debated for the past 20 years to also reduce oxidative stress by reducing the production of reactive oxygen species (ROS).² The majority of …

Timing Of Migration And Seasonal Movements Of Arctic Grayling (Thymallus Arcticus) In Relation To Water Temperature In The Kakisa River And Upper Mackenzie River, Nwt: Results From An Acoustic Telemetry Study., Levi Snook

Theses and Dissertations (Comprehensive)

Arctic grayling (Thymallus arcticus) are a cold-water salmonid that inhabit waterbodies throughout the circumpolar regions of the northern hemisphere. In the last decade, Ka'a'gee Tu First Nation members as well as local sport fishers, have observed lower catches of Arctic grayling during their annual spawning run in the Kakisa River, NWT. Many potential causes of this decline have been hypothesized including climate change and over harvesting. Outside of the general annual spawning activity in the headwaters of the Kakisa River, the ecology of the population, including post-spawn habitat use and migratory patterns, remained understudied. To address these knowledge gaps, acoustic …

“I’M Glad You're Alive.” Survivors’ Stories Of Leaving Intimate Partner Violence While Brain Injured, And The Embodied Experience Of Rebuilding Life And Relationships Post Violence., Robyn T. Mahood

Theses and Dissertations (Comprehensive)

Relationships are a fundamental part of the human experience, providing a buffer against stress and helping individuals live longer, happier, and healthier lives. However, survivors of intimate partner violence (IPV) who have experienced a brain injury (BI) encounter barriers to leaving violent relationships and engaging in new, non-violent connections. This qualitative research study drew from Indigenous and non-Indigenous methodologies to establish a blueprint for using storytelling in the IPV-BI population. Intersectionality theory, combined with critical disability theory, was employed as a transformative research paradigm to better analyze and explain the stories. Survivors encountered fear, trust concerns, continued violence from former …

Part 1 will describe the use of the dithiothreitol (DTT) assay to quantify the oxidative potential of PM through DTT consumption of redox-active field …

Terpenes Mitigate Thc-Induced Working Memory Deficits: Behavioural Evidence Of The Entourage Effect Using A 2-Component Operant Memory Task, Lara Mitchell

Theses and Dissertations (Comprehensive)

Most research on cannabis and cognitive function has focused on delta-9-tetrahydrocannabinol (THC). However, this approach overlooks the complex chemical composition of cannabis products consumed by the public, which often includes cannabidiol (CBD) and various terpenes. These additional constituents may interact with THC to modulate its effects, a phenomenon known as the entourage effect. While this theory has gained traction, experimental evidence for the cognitive impact of terpenes in combination with THC remains limited. This study aimed to assess whether terpenes can mitigate THC-induced cognitive deficits using a 2-Component Operant Memory task. Male Sprague-Dawley rats received intraperitoneal injections of either …

Integrating Indigenous Values And Community Strengths To Achieve Indigenous Food Sovereignty And Community Well-Being In The Ka’A’Gee Tu First Nation, Northwest Territories, Jennifer K. Temmer

Theses and Dissertations (Comprehensive)

Northern Indigenous communities face disproportionate impacts from interconnected challenges related to climate change, food security, health, and cultural preservation, that threaten traditional food systems and practices. While there is a growing recognition of the importance of community-driven solutions, existing frameworks fail to integrate Indigenous values and local priorities effectively. This research addresses this gap by exploring how the Ka’a’gee Tu First Nation (KTFN) is responding to these crises through climate change adaptation efforts focused on food system sustainability as a pathway to self-sufficiency and community well-being. To contribute to these efforts, this dissertation uses Participatory Action Research to facilitate community-driven …

Visual Legal Rhetoric In The Age Of Generative Ai And Deepfakes: Renaissance Or Dark Ages?, Michael D. Murray

SMU Science and Technology Law Review

The paradoxical development of visual generative AI tools, such as OpenAI’s DALL-E 3, Midjourney, and Stable Diffusion, simultaneously signals a renaissance and a potential dark age in visual rhetoric and communication. On the one hand, these tools democratize the creation of visual content, empowering attorneys and others to become artists and illustrators of their legal communications without needing to learn how to draw. These AI systems can simplify complex legal concepts, bridge language barriers, and enhance advocacy. But on the other hand, the proliferation of deepfakes presents significant challenges for visual rhetoric. Deepfakes can quickly and easily create realistic but …

The Radical Potential Of Consumer Financial Protection, Vijay Raghavan

Faculty Scholarship

This Article offers a novel retheorization of consumer financial protection that surfaces its radical potential. That retheorization is motivated by two developments. The first is the rise of debtor movements over the last decade demanding the abolition or cancellation of debt, such as the recent national campaigns against student debt and medical debt. The second is an emerging view this Article identifies in sociological and legal scholarship. Recent scholarship understands consumer financial protection as in tension with the radical ambitions of debtor movements and neoliberal in its orientation: it operates to sustain market logics as opposed to contest them.

Long-Term Increases In Wing Length Occur Independently Of Changes In Climate And Climate-Driven Shifts In Body Size, Tiffany Dias, Nathan P. Lemoine, Scott W. Yanco, Marketa Zimova, Rachael A. Bay, Brian C. Weeks

Biological Sciences Faculty Research and Publications

Recent widespread reductions in body size across species have been linked to increasing temperatures; simultaneous increases in wing length relative to body size have been broadly observed but remain unexplained. Size and shape may change independently of one another, or these morphological shifts may be linked, with body size mediating or directly driving the degree to which shape changes. Using hierarchical Bayesian models and a morphological time series of 27 366 specimens from five North American migratory passerine bird species, we tested the roles that climate and body size have played in shifting wing length allometry over four decades. We …

Consciousness Of Octopuses—On Their Own Terms, Jennifer Mather

Animal Sentience

Because cephalopods are so different from the vertebrate lineage, their possible consciousness must be assessed on the basis of their heritage and abilities. Cephalopods have evolved in water, a denser medium than air, and their perception is adapted to it. They have inherited the molluscan mantle cavity and hydrostatic muscle type, which has led to a more distributed motor control system despite a centralized brain, and have evolved a completely novel skin display system. Using these abilities, octopuses can form concepts, plan for the future, generate a cognitive map, and self-monitor for apparent pain and manipulate communication. Most cephalopods use …

Art Therapy | Master's Theses

Through the frameworks of Solution-Focused School Counseling (SFSC) and art therapy, this quantitative research paper compared the potential effects of using a physical versus a digital mandala coloring page with high school students experiencing test anxiety before a final exam. Participants took part in one of two experimental tasks before taking their exam, where they either used colored pencils to color a preset mandala or used a cellphone-based website to color in a mandala digitally. Participants completed a brief pretest-posttest State-Trait Anxiety Inventory (STAI) and answered an independent questionnaire to further understand their experience after artmaking. Data results were analyzed …

Mixed Methods Study On The Impact Of Coloring Mandalas On Emotional Regulation, Mindfulness, And Attachment Style In Adults, Rachel N. Faas

Art Therapy | Master's Theses

Abstract
This mixed methods study investigates the impact of coloring pre-drawn mandalas on adult emotional regulation, mindfulness, and state attachment style. Drawing from Attachment Theory and Art Therapy frameworks, the research evaluates whether adult coloring interventions—specifically structured mandala designs—can serve as accessible tools for improving psychological well-being. A sample of adult participants engaged in a mandala coloring intervention and completed pre- and post-assessments measuring emotional regulation, mindfulness, and attachment style, including qualitative interviews to capture subjective experiences. Results suggest that mandala coloring may promote increased mindfulness and adaptive emotional regulation strategies, with preliminary evidence indicating shifts toward more secure attachment …

Athens, Jerusalem, And Places In Between: Secular Learning And Christian Faith In Historical Perspective, Arlin C. Migliazzo

History Faculty Scholarship

Author's preface:

This novella-length essay began life as an introductory chapter in the draft version of a text on pedagogical practices in church-related higher education. The project was made possible by a $25,000 grant received by the author in 1996 from what was then known as the Lilly Fellows Program in Humanities and the Arts (now the Lilly Network of Church-Related Colleges and Universities). Fordham University Press expressed interest in publishing the book but required that the opening chapter be shortened considerably. Consequently, what eventually became Teaching as an Act of Faith: Theory and Practice in Church-Related Higher Education (New …

Rad Reduction Reveals Therapeutic Potential Of Targeting Cardiomyocyte L-Type Calcium Channel Regulation For Heart Failure, Garrett Elmore

Theses and Dissertations--Physiology

Heart failure (HF) is prevalent and is predicted to increase with the aging population. Dilated cardiomyopathy (DCM) is a common cause of systolic HF. Current therapies fail to address principal issues: compromised systolic function and dysfunctional Ca²⁺ handling. No therapeutic approach exists for direct, positive modulation of cardiomyocyte L-type calcium channels (LTCC). RAD (Ras associated with diabetes) is a key regulator of the cardiac LTCC. RAD is a downstream phosphorylated target of the ß-adrenergic receptor (ß-AR)/cAMP/protein kinase A pathway; phosphorylation augments LTCC activity, contributing to chronotropy, inotropy, and lusitropy. RAD overexpression results in LTCC inhibition, whereas knockout positively modulates …

The Geography Of Rock Glaciers In The American West, Allison Reese Trcka, Andrew G. Fountain, Bryce Allen Glenn

Geology Faculty Publications and Presentations

Rock glaciers are relatively common in conterminous United States west of the 100° meridian, yet their distribution and number are not well known. Using aerial and satellite imagery, we inventoried the population of rock glaciers, yielding 2,257 rock glaciers totaling 234.28 km² with an area of uncertainty of 7 percent. Of these, 1,561 (155.44 km²) are considered intact (moving) and 696 (76.84 km²) relict. Based on published estimates of ice content, total water-equivalent volume is roughly 2.52 km³. Rock glacier elevations increase from the northwest (Washington) to the southeast (Colorado), following a spatial …

Parents With Low Mood And Their Child: Exploring The Effects Of Group Art Therapy, Allison M. Pierce-Gay

Art Therapy | Master's Theses

This qualitative study examines the effects of group art therapy on postpartum depression (PPD) symptoms, specifically focusing on reducing isolation and improving parent–child attachment. The participants included two parents with self-reported low mood and one child (aged 2–2.5 years), and insights from eight multidisciplinary experts (clinicians, educators, and parents) were also gathered. Interventions included a somatic body scan, collage-making, and dyadic handprint painting. The results indicated reduced isolation (Likert scores improved from 3.5 to 4.75) and enhanced attachment through nonverbal co-creation; however, structural barriers (e.g., time poverty) limited sustained impact. Expert interviews identified seven themes, including grief, systemic isolation, and …

Pave Outer Space And Put Up A Parking Lot: Lagrange Points Should Be The Common Heritage Of Mankind, David A. Koplow

Michigan Journal of International Law

Outer space offers a vast array of opportunities, with different locations or regions available for exploitation by diverse users for a growing variety of satellite functions. But not all sectors of space are equally valuable for all applications, and the most desirable venues can become crowded, affording a premium for those who gain access first and impeding the development of a fair and efficient all-inclusive international legal regime.

This article focuses on Lagrange points, a finite series of special locations in space where the gravitational forces from a pair of large celestial bodies interact in unusual ways. These points afford …

The Economic Structure Of Trade Secret Law, Tun-Jen Chiang

Minnesota Law Review Vols. 106:2 onward (2021-present)

The standard economic account of trade secret law focuses on providing incentives for creating new inventions. The incentive-to-invent theory, however, provides little explanation for why the key doctrinal features of trade secret law are structured the way that they are. For example, providing ex ante incentives to invent does not easily explain the requirement that an inventor must take measures to preserve secrecy even after the invention has been created. Nor does it explain why trade secret misappropriation, unlike patent and copyright infringement, requires “improper” conduct by the defendant for liability. This Article gives a different theory of trade secret …

All Wrapped Up: How Choice Of Egg Wrapping Substrate During Oviposition Site Selection Affects Predation And Embryonic Growth In Eastern Newts, Anna Prohofsky

Master’s Theses

Parental care behaviors have a significant impact on the survivorship of offspring and therefore the inclusive fitness of the parent. These behaviors are broad and varied and include defending against predators, acquiring food, and choosing where to lay their eggs. The latter, oviposition site selection, has significant impact on embryo survivorship in oviparous animals, as the chosen sight can impact factors such as incubation temperature, predation risk, and resource availability. For amphibians, oviposition site selection is particularly crucial as their eggs lack a calcareous shell, leaving them more susceptible to environmental conditions and predation. In response to this, amphibians have …
