First-Year Seminar’S Influence On Thriving In First-Year Students, Chelsea Miller

Dissertations

First-year students struggle with attrition. Prevention of attrition has various interventions on such first-year seminars. Typically, these interventions use academic outcomes to measure effectiveness. Prior research supports that students enrolled in first-year seminar benefit academically from the intervention. However, these outcomes do not fully capture all the possible benefits of this intervention. This leaves room for research on other possible outcomes. Thriving as a construct incorporates both academic and social elements. Thriving is a possible outcome that could capture the benefits of first-year seminars. This study examined how much of the variance in thriving was explained by participation in first-year …

Practices And Strategies Used In Classrooms For Children Who Are Deaf With Autism, Jennifer Anne Hills

Dissertations

Deaf education has a history spanning more than 200 years; however, there remain relatively few evidence-based practices specifically identified for use with children who are deaf or hard-of-hearing (DHH; Cawthon & Carrie, 2021). In contrast, autism as a diagnostic and educational category is a much more recent phenomenon. Just over 80 years ago, Donald Triplett, became the first person diagnosed with autism in the United States (Donovan & Zucker, 2016). The diagnosis and education of autism is a newer phenomenon with strong research underpinnings. Conversely, the field of deaf education has existed for over 200 years, yet few evidence-based practices …

The Use And Efficacy Of Non-Verbal Gestures In Applied Studio Voice Instruction And Vocal Coaching, Mark Eugene Lubas

Dissertations

Despite important innovations in the use of technology in vocal instruction, individualized, faceto- face communication remains the predominant delivery modality for applied voice lessons and vocal coaching. Applied voice instructors and vocal coaches consistently identify non-verbal, gestural communication as a significant dimension of these instructional interactions. Existing scholarship has examined the expressive use of gesture in musical performance, the role of gesture in facilitating pitch accuracy acquisition among young singers, and the neurological responses of singers to gestural input. However, systematic investigation of gesture as a pedagogical instrument from the perspective of the instructor remains underdeveloped in the literature. This …

Reconsidering The Undergraduate Viola Canon: A Skill Based Framework For Repertoire Expansion, Daniella Isabel Angulo Martinez

Dissertations

This research analyses the limitations of the standard undergraduate viola repertoire and proposes a structured, skill-based framework for its expansion. Within collegiate viola programs in the United States, training frequently focuses on a limited group of orchestra-accompanied works, particularly those by Telemann, Stamitz, Bruch, and Walton. While these works have a great pedagogical value, their dominance has contributed to a restricted repertoire that can limit students’ technical development, musical style knowledge, and artistic growth.

Based on the pedagogical standards of the American String Teachers Association (ASTA), this research identifies five core performance domains - technique, rhythm, intonation, tone projection, and …

Feedback Without Content Expertise: Exploring Teacher Perception Of Effective Feedback In Teacher Evaluations With Content Mismatch, Anna Keathley Bergeron

Dissertations

A key element of teacher evaluation systems is to support professional growth by providing teachers with feedback on their instructional practices and identifying opportunities for improvement. Despite this intent, research consistently indicates that teachers often perceive evaluation feedback as vague, generic, or disconnected from their instructional context. These concerns are particularly evident at the secondary level, where evaluators frequently assess teachers outside their area of content expertise. As a result, recent research suggests that a lack of content knowledge may serve as a barrier to providing meaningful feedback.

The purpose of this qualitative instrumental case study was to examine how …

Social Correlates Of Trauma And Posttraumatic Stress Disorder: The Importance Of Context, Lukoye Atwoli, Linnet Ongeri

Internal Medicine, East Africa

Leveraging Code Embeddings To Identify And Address Blind Spots In Benchmark Creation, Charles Moloney

School of Computing: Dissertations, Theses, and Student Research

Formal software verification remains critical for early vulnerability detection, yet benchmarking these tools is costly and often reliant on centralized datasets such as SV-COMP. While such repositories enable standardized evaluation, they introduce risks of overfitting and bias, particularly due to first-party benchmark contributions. To address these limitations, we extend ARG-V, our tool for generating SV-COMP-compatible benchmarks from real-world Java code, with a novel approach of using code embedding techniques to selectively sample from mined code. By leveraging Nomic Embed Code and a cosine-based Minimum Hyperspherical Energy (MHE) objective, we systematically select and transform benchmarks from scraped GitHub code that …

Real-Time Adaptable Residential Kitchen: A Plug-In Standard, Rachel Fuelberth

Masters in Architecture Program: Theses

This thesis looks at how a real-time adaptable standard could be put in place within the modern kitchen to allow for equitable use of the space by numerous members of the household and their differing physical characteristics. The residential kitchen is a fundamentally exclusionary architectural construction designed around able-bodied, average-height adults. This excludes children, the elderly, anyone outside of the average height, and people with mobility differences. The kitchen has never been a place of equity. It has been designed to be used by an average-height female, and it does not account for the discomfort of those outside this norm. …

Design And Development Of A Passive Dust Protection System For Lunar Docking Operations, Simon Thengvall

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Lunar docking systems face a unique set of environmental conditions that can create significant challenges for mechanical design. Among these, the abrasive nature of lunar regolith can impair the kinematic function of traditional terrestrial mechanisms as well as contaminate critical spacecraft components such as environmental seals, causing them to fail. For crew-rated docking systems, failure of these systems not only threatens mission success, but also crew safety, so dust protection is crucial for docking components. To address the concerns of regolith intrusion, the Simple External Attachment for Lunar Openings (SEALO) is developed as a key architecture for mechanism evaluation when …

Decomposition Study Using Pigs In Southeastern Nebraska During The Fall And Winter Seasons, Ryan Bodine

Department of Anthropology: Theses and Student Research

When an individual is found deceased, one of the tools used in the identification process is estimating the post-mortem interval (PMI). This estimate is used to determine how long an individual has been deceased once their remains are found. To estimate an accurate PMI, knowing how decomposition is affected by external factors is key. The transition period from fall to winter in southeastern Nebraska consists of fluctuating temperatures as the seasons transfer from fall to winter. This thesis investigates how decomposition is affected during this transition period while also looking at two different environments that are common in Nebraska, prairies …

Exploring The Biocultural Profile Of The Undocumented Populations Of The Sonoran Corridor: A Skeletal Assessment Of The Prevention Through Deterrence Strategy, Mary A. Vaughn

Department of Anthropology: Theses and Student Research

Over the last thirty years the mortality rate of the undocumented population at the US-Mexico border has risen, requiring methods distinguishing US-born individuals from immigrants to improve the likelihood of identification and repatriation through foreign consulates. Forensic anthropologists with the Pima County Office of the Medical Examiner (PCOME) have advocated for the use of the biocultural profile, combining the biological profile with factors including oral health, osteological stress, and personal effects. The biocultural profile serves two purposes, functioning both as a tool for identification and with which to document structural inequality within communities of origin.

This study examines changes in …
