America The Not Yet Beautiful: Unfulfilled Promises In A Racist-Capitalist Society, Kaitlyn Tibbetts

Theses and Dissertations

This thesis draws from Langston Hughes’s poem “Let America Be America Again” to analyze four American novels that demonstrate the United States’s unfulfilled promises for lower-class individuals and minorities. The four novels examined in this thesis include: The Outsiders by S. E. Hinton, The Nickel Boys by Colson Whitehead, There There by Tommy Orange, and How the García Girls Lost Their Accents by Julia Alvarez. Utilizing theoretical frameworks such as social reproduction theory, intersectionality, and Burden-Shelly’s theorizations on racist-capitalist oppression, this thesis argues that the policies and systems that the U.S. is founded on are designed to primarily benefit economically …

Classifying Mathieu-Zhao Subspaces In Products Of Cyclic Rings, Sarah A. Huber

Theses and Dissertations

Mathieu-Zhao subspaces are a generalization of ideals in an algebra and were introduced by Wenhua Zhao in connection to the Jacobian conjecture and its variants. These subspaces have interesting properties, and often the problem of classification is hard. In this thesis, we investigate the structure of Mathieu-Zhao subspaces of the cartesian product of integers modulo powers of a prime p, Zpr × Zps . We will give a complete classification of the subgroups, maximal subgroups, Mathieu-Zhao subspaces, and maximal Mathieu-Zhao subspaces in these rings.

The Role Of Non-Academic Staff In First-Year Retention At Regional, Comprehensive Universities, Marco A. Krcatovich Ii

Theses and Dissertations

Regional comprehensive universities (RCUs) serve a large share of U.S. undergraduates, yet the role of non‑academic staff in shaping first‑year retention remains understudied. This dissertation examines how staff diversity and staffing structures relate to student persistence using seven years of IPEDS panel data and Linear Mixed‑Effects Models. Analyses were conducted separately for residential and commuter RCUs to reflect their distinct engagement environments. Findings show that staff diversity is significantly associated with retention, though the direction and magnitude vary by campus type and staff role. Staffing structure also matters as higher proportions of full‑time staff are positively associated with retention at …

Reconciliation, Draper Matthews

Theses and Dissertations

This thesis exhibition, Reconciliation, examines how memory, loss, and lived experience shape personal identity over time. Through sculptural works composed of cast, blown, and hot-sculpted glass combined with mixed media, the exhibition explores the pressures that life events place upon individuals and the ways those pressures persist, transform, and become integrated into the self. The work considers identity not as a fixed state but as a continual process of negotiation between past experiences, present circumstances, and future possibilities.

Central to the project is the material analogy between glass and human experience. Glass, a material formed under extreme heat and pressure …

Emotion Regulation Difficulties And Substance Use: The Role Of Conscientiousness, Caitlyn M. Donnelly

Theses and Dissertations

Difficulties in emotion regulation have been consistently linked to substance use among college students. However, individual differences may influence this relationship. Conscientiousness, a personality trait characterized by self-control, planning, and goal-directed behavior, has been proposed as a potential protective factor. The present study examined associations among difficulties in emotion regulation, conscientiousness, and substance use behaviors, as well as whether conscientiousness moderates the relationship between emotion regulation difficulties and substance use. Using a quantitative, cross-sectional, correlational design, data was collected from college students recruited through a university participant pool. Participants completed self-report measures of emotion regulation difficulties, conscientiousness, and substance use …

Theses and Dissertations

This study examined whether student success outcomes and their trajectories over time differed across higher education institutions before, during, and after the COVID-19 pandemic based on prior experience with online education. Guided by Astin’s (1993) Input-Environment-Output (I-E-O) framework, pre-pandemic participation in online coursework was conceptualized as an institutional-level environmental condition. A quantitative, causal-comparative research design was employed, using secondary data from the Integrated Postsecondary Education Data System (IPEDS), to examine longitudinal differences in institutional retention and graduation rates across institutions classified by their pre-pandemic participation in online education. The sample included 528 Title IV-eligible, degree-granting, four-year institutions observed across five …

Examination Of The Effects Aesthetic Enrichment And Music Have On Well-Being And Task Performance In A Workplace Simulation, Emily Budik

Theses and Dissertations

Workplace environments are often designed with a focus on efficiency, yet emerging research suggests that environmental features such as aesthetic enrichment and music may influence employee well-being and performance. The present study examined whether visual aesthetic enrichment and auditory stimulation through music could improve well-being, reduce stress, and enhance task performance within a simulated workplace task. Participants completed a 30-minute in-basket task under one of four conditions: a control environment, music only, aesthetic enrichment only, or a combined aesthetic enrichment and music condition. Measures of stress, well-being, and task performance were collected following task completion. Results indicated that neither aesthetic …

The Acculturation Of International-Born Student Affairs Administrators In The United States, Amber Joy Webb

Theses and Dissertations

This qualitative narrative study explored how international student affairs administrators in the United States experience acculturation. Guided by Berry’s (1997) fourfold model of acculturation, the study examined how participants experienced assimilation, integration, separation, and marginalization as they navigated their professional roles, institutional expectations, and cultural identities. Eight participants, representing diverse countries of origin, institutional types, and professional roles, were interviewed using a semi-structured interview guide. Data were analyzed using Braun and Clarke's (2006) framework. Findings indicated participants employed multiple, context-dependent acculturation strategies rather than adhering to a single strategy. Assimilation emerged as a strategic process for establishing professional legitimacy, navigating …

Parental Behavior, Attachment, And Sibling Outcomes In Asd Families, Bridget W. Mwaura

Theses and Dissertations

Neurotypical siblings of individuals with Autism Spectrum Disorder (ASD) often experience unique challenges, including increased familial stress and differences in parental treatment, which may affect the sibling bond. Grounded in the Attachment Theory and Siblings Embedded Systems Framework, this study examined relationships among attachment security, parenting behaviors and sibling relationship quality. It was hypothesized that secure parental attachment and helpful parenting behaviors would predict greater sibling closeness and lower conflict, and that attachment security would mediate the relationship between parenting behaviors and sibling relationship quality. Results from a sample of emerging adults (N=91) partially supported these hypotheses. Bivariate …

Theoretical Analysis Of Filtering And Smoothing Techniques In Stochastic Time Series, Kaosarat Bola Azeez

Theses and Dissertations

Polynomial-preserving linear filters are fundamental tools for smoothing and trend extraction in noisy time series, particularly when the objective is to reduce short-run variation without distorting underlying low-degree structure. This thesis develops a general framework for such filters based on local polynomial approximation and least-squares estimation. In particular, we establish that the resulting estimators can be represented as symmetric linear filters whose weights satisfy moment conditions that ensure exact polynomial reproduction up to a specified degree. Building on this framework, we derive explicit coefficient vectors for several classical smoothing filters, including the Savitzky-Golay filters SG(5,2) and SG(7,3), as well as …

Create Your Character: Application Of Identity Play Findings From Cosplay And Video Games Onto Tabletop Roleplaying Games, Farhia A. Osman

Theses and Dissertations

Tabletop roleplaying games (TTRPGs) are collaborative, imaginative games in which players create and enact fictional characters within shared narrative worlds. Although research on roleplaying games has expanded in recent years, much of the empirical literature has focused on digital roleplaying games, particularly massively multiplayer online roleplaying games, leaving tabletop roleplaying comparatively understudied. I conducted a study with 173 adult TTRPG players to examine the relations among openness to experience, motivations for playing TTRPGs, and avatar identification. I also explored whether the individual facets to openness to experience predicted motivations for play and avatar identification, and whether players who had portrayed …

Tooth Ablation And The Jōmon - Yayoi Transition In Japan, Laura R. Erickson

Theses and Dissertations

The Jōmon – Yayoi period transition in Japan is marked by many migrants coming through the Korean Peninsula into Kyushu, sparking changes such as the introduction of wet-rice agriculture to the native hunter-gatherer-fisher Jōmon population and decreases in tooth ablation patterns and percentages. Ritual tooth ablation, or the removal of healthy front teeth, is typically seen as a coming-of-age practice, with the Jōmon having a diverse amount of ablation patterns. In this study, I explored how the rates and variation of tooth ablation changed throughout Japan after the arrival of Yayoi migrants from the continent. After calculating ablation rates per …

An Evolution Of Drag In Theatre: A Historical Reflection, Krista Peters

Theses and Dissertations

Transgender Representation In Japanese Video Games And Their Corresponding American Fandoms, Aj Abad

Theses and Dissertations

This thesis explores transgender and gender non-conforming characters within Japanese media and their corresponding American fandoms. In this thesis, I use a methodology named trans negotiated readings, stemming from Stuart Hall’s theory of dominant codes and negotiated readings. Through focusing on two characters from two different Japanese media—Arashi Narukami from Ensemble Stars!! and Mizuki Akiyama from Project Sekai: Colorful Stage Feat. Hatsune Miku, I uncover some of the dominant codes encoded the original source material. After, I also examine their corresponding American fandoms, uncovering the negotiated readings from the fanbase. This thesis attempts to show different cultures’ interpretation of transgender …

Interactive Effects Of Bti Larviciding And Predation On Culex Pipiens And Its Ephemeral Pond Communities, Jaclyn S. Everly

Theses and Dissertations

Populations of adult vector mosquitoes can be controlled by reducing larval mosquito abundances in aquatic habitats. This can be achieved via predation by introduced or naturally-occurring enemies (i.e., biocontrol or conservation control) or by applying pesticides to larval mosquito habitats (i.e., larviciding). The larvicide Bacillus thuringiensis israelensis (Bti) is commonly applied to ephemeral ponds to control populations of Culex pipiens mosquitoes that vector West Nile virus. However, there is concern that Bti may directly or indirectly harm non-target organisms such as dragonfly and damselfly naiads, which provide a natural source of mosquito biocontrol. Bti or predators may also induce positive …

The Effect Of Sex On The Signal Transmission Of Duetting Bay Wrens, Rachel C. Schinzler

Theses and Dissertations

During communication, senders send signals for their benefit to elicit a behavioral response from a receiver. Acoustic signals are efficient for long-distance signaling; however, they are influenced by environmental features, such as foliage density, humidity, temperature, and time of day. Individuals can overcome these challenges by using signals with a trajectory of peak frequency, frequencies, volumes, and timing best suited to signal transmission in their environment. Signal transmission has been studied at the species level; however, not much is known about sex differences within the same species. Duetting species provide a useful system for examining sex-specific challenges in transmission, as …
