Lineup Construction Strategies In The Presence Of Within-Person Variability, Abbey M. Greenfield

Student Theses

Photographic lineups are used more frequently than live lineups, but photographs are not always reliable representations of a person’s appearance. Oftentimes, images used in lineups are drawn from mug books, passports, and driver’s license photographs—which may be outdated. As a result, even when a culprit is correctly identified for inclusion in a lineup, the photograph used may differ significantly from their appearance during the event due to natural changes in appearance (Jenkins et al., 2011). Further, the degree of suspect-filler similarity sufficient to achieve optimal discriminability remains a topic of debate (Fitzgerald et al., 2013). We examined the impact differing …

Voltage-Sensor–Targeting Modulators Of Iks: Identifying Critical Functional Groups Of C28 Via Electrophysiology And Sar Modeling, Jiacheng Huang

McKelvey School of Engineering Graduate Student Theses & Dissertations

I_Ks (KCNQ1/KCNE1) channels are essential for cardiac repolarization, and their dysfunction contributes to arrhythmogenic disorders such as Long QT Syndrome type 1 (LQT1). Pharmacological activation of I_Ks has therefore emerged as a promising therapeutic strategy. C28, a recently identified voltage-sensor–targeting activator, has been shown to markedly shift KCNQ1/KCNE1 voltage dependence and enhance current amplitude, validating the voltage-sensing domain (VSD) as a druggable site. However, the structural determinants that underlie C28’s activity remain incompletely understood. In this study, we aimed to identify critical functional groups of C28 by screening a structurally diverse set of C28-like analogs and evaluating their …

Toward Vehicle-Agnostic Driving Signatures For Cognitive Impairment Prediction From Naturalistic Driving Data, Aadarsha Gopala Reddy

McKelvey School of Engineering Graduate Student Theses & Dissertations

This thesis studies whether naturalistic driving data can help predict binary Clinical Dementia Rating (CDR) status while accounting for differences across vehicles. The final analytic dataset comprised 26,968 participant-weeks from 304 participants. Weekly driving features were derived from real-world telematics data and combined with four demographic covariates. Primary model comparisons used leave-one-participant-out (LOGO) cross-validation, with one individual held out at a time and pooled participant-level metrics used as the main reporting surface.

The main comparison includes six model families evaluated on the same dataset under a shared LOGO framework. Performance remained modest overall. GRU-DANN had the highest participant-level ROC AUC …

Improving Semantic Precision In Text-To-Image Diffusion Models Via Latent-Space Optimization And Semantically-Parsed Evaluation, Mohammad Rouie Miab

McKelvey School of Engineering Graduate Student Theses & Dissertations

Text-to-image diffusion models can produce visually impressive images from natural-language prompts, but they often fail to satisfy the detailed semantic constraints expressed in compositional prompts. Typical failure modes include omitted objects, merged entities, incorrect quantities, incorrect attribute binding, and leakage of one entity's attributes onto another. This thesis studies the problem of semantic precision in text-to-image generation: how faithfully a generated image satisfies the structured meaning of its prompt.   The thesis makes two linked contributions. First, it presents a training-free inference-time refinement method for diffusion-based image generation. The method operates directly in latent space during denoising and uses noun-phrase-aware cross-attention …

Interaction-Aware Safe Planning For Human-Robot And Multi-Robot Systems, Haoyi Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Robots operating in shared environments must interact safely not only with static obstacles but also with other decision-making agents, including humans and other robots. In such settings, both safety and task completion depend on the ability to reason about interaction. Two major challenges arise. In human-robot interaction, future human behavior depends on latent internal factors, such as attentiveness and behavioral style, that are not directly observable to the robot. In multi-robot systems, decentralized reactive navigation can fail in cluttered environments when reciprocal interactions create deadlocks that prevent progress through narrow passages or bottlenecks. This thesis investigates these two challenges from …

Temperature And Environmental Implications On Ti3c2cl2 Mxene Degradation Process, Yang Yang

McKelvey School of Engineering Graduate Student Theses & Dissertations

MXenes, a rapidly emerging class of two-dimensional transition metal carbides and nitrides, have attracted considerable attention owing to their exceptional electrical, mechanical, and chemical properties. However, the inherent thinness of their atomic structure and the reactivity of their functional groups render MXenes susceptible to environmental degradation, whereby the lattice integrity is compromised and desirable material functionalities are dimin- ished. In this work, ex situ electron microscopy characterisation is performed on Ti₃C₂Cl₂ MXene specimens subjected to controlled gas environments — nitrogen gas (N₂) and air — at annealing temperatures of 200°C and 600°C, with …

Unfixed Bodies, Soph Shufelt

Theses

This thesis emerges from that tension between protest and living.  It considers what it means to have one’s existence continually framed as resistance, and how that condition reshapes embodiment, temporality, and identity.  By situating my lived experience within broader social and political structures, I examine how bodily autonomy functions not only as a personal necessity, but as a regulated site of power.  The work that follows investigates how queer and transgender bodies navigate visibility and risk, how time is warped through prolonged struggle, and how survival becomes a form of authorship.

Neuroarchitecture: Color Psychology And Its Impact On The Built Environment, Jean Morgan

Theses

Neuroarchitecture merges neuroscience and architecture, examining how built environments affect our emotions, behaviors, and overall well-being. One of the principles of this interdisciplinary topic focuses on Color psychology, which explores the profound influence of colors on human emotions, behaviors, and cognitive responses. In the built environment, the strategic use of color extends beyond aesthetics, shaping user experiences, functionality, and psychological well-being. This thesis explores the interplay between color psychology and architectural design, highlighting how color choices influence mood, productivity, and social interactions within spaces. The main focus will examine the relationship between colors and equal causation in psychological effects. The …

Hiit Vs. Mict: Effects On Predicted Vo2 Max & Body Fat Percentage In Adults (8 Weeks), Rebekah Holden

Doctorate in Kinesiology

The purpose of this study was to investigate the impact of High-Intensity Interval Training (HIIT) compared to Moderate-Intensity Continuous Training (MICT) on predicted VO2 max and body fat percentage in adults over an 8-week period. Despite the World Health Organization’s physical activity recommendations, nearly 1.4 billion people fail to meet these goals, primarily due to time constraints, contributing to a 30% global increase in obesity. Cardiorespiratory fitness (CRF) is a definitive predictor of all-cause mortality; however, research remains divided on whether low-volume HIIT or traditional MICT is superior for metabolic and cardiovascular adaptation in non-clinical populations. This study compared the …

The Use Of Video Laryngoscopy In Pregnant Women Undergoing Non-Obstetric Surgery, Samantha Gastaldo

Doctor of Nursing Practice Scholarly Projects

This quality improvement project looks at the proposed implementation of endotracheal intubation guidelines regarding pregnant patients undergoing non-obstetric surgery and how the use of video laryngoscopy versus the traditional practice will affect the first pass rate of the endotracheal tube intraoperatively. Statistics show that 2% of women undergo non-obstetric related surgery during pregnancy. Physiological changes during pregnancy, including increased laryngeal mucosa swelling and higher metabolic oxygen consumption, result in a heightened risk of apnea and hypoxemia during intubation. Pregnant women experience an eightfold higher incidence of failed intubation compared to non-pregnant populations. The number of patients classified as Mallampati 4 …

Leading A School District During The Covid-19 Pandemic, Teresa M. Murphy Phd

Educational Studies Dissertations

The COVID-19 pandemic altered the conditions of district leadership and required superintendents to make high-stakes decisions amid uncertainty, public scrutiny, and sustained operational disruption. Although scholarship on educational crisis leadership has expanded, fewer studies center superintendents’ own accounts of the knowledge, skills, and conditions that shaped their leadership during COVID-19, and its professional impact. This phenomenological study examined district-level crisis leadership during the first two years of the pandemic, with attention to crisis problem solving, role isolation, crisis communication, and superintendent sustainability. Three research questions guided the study: (1) What knowledge and skills did superintendents perceive necessary for leading during …

Speaking Of Language: The Relationship Between Language As Capital And Minority Language Education, Alex J. Zelaya

Politics Honors Papers

The future of minority languages not only depends on intergenerational transmission but also on support for immersive instruction in minority languages within the educational system. This paper examines the factors that influence support for minority language education, arguing that language policy is shaped by societal attitudes, which in turn reflect dynamics of power. The paper draws upon Pierre Bourdieu’s conceptualization of different types of capital, including his theory on the relationship between economic, social, cultural and symbolic capital. Within this framework, language functions as a form of capital, reflecting and reinforcing social and economic stratification by conveying status or stigma. …

Increasing Safe Driving Among Adults With Neurological Impairments In A Rural Setting, Melissa V. Burt

Occupational Therapy Capstone Presentations

This capstone project examined challenges related to safe driving for adults living in rural communities with neurological impairments. Guided by the Person-Environment-Occupation Model and Toglia's Dynamic Interactional Approach, the project focused on increasing awareness, accessibility, and utilization of occupational therapy (OT) led assessments, community-based services, and educational outreach on driving safety. Clinical skill development was demonstrated through standardized and informal assessments and evidence-based interventions with adults with neurological conditions. Program implementation included driving risk assessments, one-on-one CarFit sessions, the creation of educational pamphlets, and educational presentations to increase community and provider awareness of OT's role in driving rehabilitation. CarFit surveys …

Taking Off The Mask: Development Of A Role Method For Late-Diagnosed Neurodivergent Women, Maria Moutzalias

Expressive Therapies Theses

Neurodivergent women are frequently underdiagnosed, misdiagnosed, or late diagnosed due to gender differences and the prevalence of masking. Masking is the unintentional or intentional suppression of neurodiverse traits to present more neurotypical. Consequences of long-term masking can include increased risk of anxiety, depression, and burnout. This study explores the potential of drama therapy as a modality to support unmasking and increasing self-esteem in neurodivergent adult women. Drawing on existing literature on neurodiversity, masking, and drama therapy, a two staged role-based intervention was developed and implemented within a six weeklong psychotherapy group for five late diagnosed neurodivergent women. All participants were …

Playing The Part Online: A Role-Based Telehealth Intervention Supporting Trauma Integration In Adults, Mary Schwabenland

Expressive Therapies Theses

This study explores a telehealth-adapted, role-based drama therapy intervention designed to support trauma integration in adults. Grounded in trauma theory, experiential approaches, and drama therapy frameworks, the intervention utilized interoceptive awareness, metaphor, and role embodiment to explore emotional material in dramatic reality, with aesthetic distance serving as an adjustable mechanism of activation and containment. A qualitative thematic analysis was conducted on clinical session notes from five adult clients. Five themes emerged from the analysis, including: aesthetic distance and modes of engagement; aesthetic quality and symbolic coherence; role narrative as integration pathway; intervention as catalyst within ongoing process; and therapist positioning …

Reclaiming Identity, Vu Do

Expressive Therapies Theses

This study explores how narrative-informed art therapy supports identity, emotional expression, and social connection among older adults living with early-stage dementia. Traditional talk-based therapies often rely on verbal communication and memory recall, which can limit their effectiveness for individuals experiencing cognitive decline. Art therapy offers a nonverbal, sensory, and visual modality that allows for expression beyond language, while narrative therapy emphasizes meaning-making, identity, and the reauthoring of personal stories. Using a qualitative, narrative-informed art therapy approach, this study followed one older adult diagnosed with early-stage dementia across five sessions involving art-based directives and reflective dialogue. Data was collected through session …

Co-Active Therapeutic Filmmaking: A Methodology Pilot Project, Blair Webber

Expressive Therapies Theses

This pilot project examined the intersection of drama therapy and filmmaking. Drawing on the Co-Active Therapeutic Theater model from drama therapy and digital storytelling and participatory video methods from social work research, this methodology designed and delivered a co-created filmmaking intervention at a residential treatment center for adult men with co-occurring mental health and substance use disorder. Four participants made a seven-minute-long short fictional film based on their definition of active recovery and a theme of recovery they wished to share with an audience. It was screened at the treatment center for staff and their fellow residents. Data collection was …

How Can Art Therapy Intergenerational Groups Support Fostering Connections For Individuals With Memory Loss?, Clara Drew

Expressive Therapies Theses

This thesis explores the question: How can art therapy intergenerational groups support fostering connections for individuals with memory loss? In the study conducted, there were two separate groups, family-based and community volunteer-based. Both included residents of a memory care community. Through the process of this study, a total of seven groups were conducted. These groups explored art activities that focused on fostering connection through sensory and collaborative art processes. The study noted changes in the residents' moods, level of engagement, collaboration and socialization, and post-group affect throughout the day. While the focus was observing these factors for memory care residents, …

Exploring Identity Development In Adolescents Through A Series Of Self-Portrait Making Using Art Therapy, Kayla Lincoln

Expressive Therapies Theses

This study explored how self-portrait making in art therapy can support adolescent identity development. This concept was implemented through a three-part series of self-portrait directives (past, present, and future self) in a group setting at an adolescent partial hospitalization program (PHP). There were a total of 7 participants in this study, ranging in age from 14 to 17 years. Data was collected through note-taking of observations and expressions of participants and their artwork. Using thematic analysis, three themes were identified from the three group sessions: influence of others on identity, identity as an evolving process, and resilience and growth. Findings …

Queer Creativity In A State Of Surveillance: Community Art-Making As Embodied Resistance, Rachel "Frankie" Uhrig

Expressive Therapies Theses

This thesis explores the relationship between community art-making and queer resilience in response to state-sanctioned violence and surveillance. Furthermore, this paper focuses on the impact of visibility/invisibility on individuals within a community that is heavily policed and how less Eurocentric, medicalized approaches to support can serve these individuals. To better study and understand this approach, multiple sessions of community-based open studios were held from the writer’s home. Research was gathered from a group of individuals already in community together through the spectrum of queerness within a roller derby team. Participants were given a variety of materials to work with and …
