Challenging Myths In Speech-Language Pathology: A Scientific Review Of Augmentative And Alternative Communication (Aac) Use, Bilingualism, And Late Talking, Mariah Morris

Undergraduate Honors Capstone Projects

Persistent myths within the field of speech-language pathology continue to influence clinical decision-making and contribute to biases experienced by both providers and clients. This scientific review examines common misconceptions surrounding late talking, bilingualism, and augmentative and alternative communication (AAC) by evaluating current evidence-based research. Specifically, this review addresses three central questions: Do children outgrow late talking? Does bilingualism cause language delay in children? Does AAC hinder speech development? 

An analysis of multiple peer-reviewed studies revealed little statistical support for the belief that bilingualism or AAC use causes language delays. Instead, research indicates that factors such as limited access to language-rich …

Learning From 2002: County-Level Economic Analysis Of The Salt Lake City Winter Olympics And Implications For Utah 2034, Ronan Spencer

Undergraduate Honors Capstone Projects

This paper examines economic and distributional impacts and the existing literature on the 2002 Salt Lake City Winter Olympics to inform policy recommendations for the upcoming 2034 Utah Olympic Games. Using a difference-in-differences (DiD) framework on county-level data from 1995 to 2006, we compare Utah host counties to Colorado counties. Results indicate that the Games generated an average of 1,084 Leisure and Hospitality jobs per host county, suggesting approximately 5,420 total jobs across all five host counties. We saw a positive but marginally significant increase in tourism and hospitality GDP of $37.2 million relative to Colorado controls (p=0.078). We also …

Energy Poverty In U.S.-Mexico Border Communities: A Mixed-Methods Study Of Lived Experiences In El Paso And Laredo, Texas And Quantitative Patterns In Brownsville, Texas, Felipe Israel Martinez

Open Access Theses & Dissertations

Energy poverty in the U.S.-Mexico border region remains understudied, and much of the existing literature overlooks the lived experiences of households in this region. This thesis examines the lived experiences and coping strategies of residents in El Paso and Laredo, Texas, while also analyzing the sociodemographic variables associated with electric disconnection in Brownsville, Texas. The study employs a mixed-methods design that combines a quantitative ZIP code-year panel of electric disconnections in Brownsville, Texas from 2015 to 2024 with 14 qualitative interviews conducted with residents in El Paso and Laredo, Texas who had experienced electric disconnections or shutoff notices. These two …

Public Art And The Future Of Remembrance In Contested Spaces, Rebecca Ann Munoz

Open Access Theses & Dissertations

This dissertation examines the memorial landscape of El Paso, Texas as a contested site of public memory, cultural identity, and community representation. Situated at the U.S.-Mexico border, El Paso functions as a palimpsest of layered histories shaped by colonization, militarization, and ongoing negotiations of belonging. Drawing on memory rhetoric and composition studies, and art history, the paper raises critical questions about community engagement, representational equity, and the politics of visibility in public art processes. The paper ultimately calls for a deeper examination of the rhetorical strategies and institutional frameworks that shape memorial meaning-making at the local level, with broader implications …

Open Access Theses & Dissertations

This autoethnographic study, Bridging Leadership: An Autoethnographic Inquiry into the Governance and Decision-Making Experience of a Latina Rural School Superintendent, examines how governance and leadership are experienced and enacted through the sustained relationship between a superintendent and a school board president in a rural border district along the U.S.-Mexico border, the study explores how power, trust, reciprocity, role expectations, and ethical tension evolve within this leadership partnership over time. Grounded in Relational Leadership Theory, Social Exchange Theory, and Role Theory, the study conceptualizes leadership as a relational and contextually embedded process rather than a function of positional authority. Using autoethnography …

An Analysis Of The War On Terror In Textbooks, Kason Kendall

All Graduate Theses and Dissertations, Fall 2023 to Present

This study analyzes how the War on Terror is presented in history textbooks used in the United States and Brazil. Textbooks play an important role in shaping how students understand major global events, including wars, national security, and international relations. However, these materials do not simply present facts, they also reflect specific perspectives and priorities.

The purpose of this study is to analyze how key topics related to the War on Terror, such as the justification for the Iraq War, domestic security policies, treatment of prisoners, and public dissent are portrayed in textbooks from other countries. By comparing these narratives, …

Equity, Diversity, And Inclusion Infrastructures And Faculty Composition: Associations With Undergraduate Student Outcomes At R1 Universities 2011-2021, Niyonta Nahia Chowdhury

All Graduate Theses and Dissertations, Fall 2023 to Present

This study explores how the structure and composition of research universities relate to student outcomes. Specifically, it asks whether having visible Equity, Diversity, and Inclusion (EDI) infrastructures and diverse faculty representation is associated with who enrolls, who graduates, and how graduation rates differ within racial groups at R1 universities in the United States. Using national data from 2011 to 2021, the project analyzes enrollment and graduation patterns across institutions while accounting for differences in geography, governance, and state political context.

Rather than focusing on individual students, the study looks at institutional patterns. It examines how the racial and gender makeup …

Housing Markets In The American West: A Dynamic Time Warping Analysis Of Inter-City Relationships, Daniel Johnson

All Graduate Theses and Dissertations, Fall 2023 to Present

Housing markets revolve around perhaps the most consequential good to the average person, yet the relationships between local housing markets remain understudied. While major American cities appear to follow similar patterns, the nature of these connections is not fully understood. This project looks at housing markets across the western United States, using Dynamic Time Warping (DTW) to identify which cities tend to lead or lag others in price movements, and look at the overall similarity of their market movements. We also explore whether geographic distance, population growth, and income growth help explain why some markets are more similar than others. …

Great Power Competition In Africa: U.S. Aid Responses To Chinese Aid And Investment, Ebenezer Nana Botsio

All Graduate Theses and Dissertations, Fall 2023 to Present

Over the past two decades, China’s rapid expansion of aid and investment throughout sub-Saharan Africa has raised questions about how the United States responds to growing competition in the region. While the impact of China’s aid has been the subject of considerable study, far less attention has been given to how other donors shift their strategies to adjust. This thesis asks a simple but rather consequential question: does the US change how it gives aid in Africa in response to China’s ever-growing footprint? 

With data from 54 African countries, I find that the United States does not attempt to directly …

Assessing Geomorphic Change From Large Wood Additions In An Intensively Monitored Watershed, Alexander Walt

All Graduate Theses and Dissertations, Fall 2023 to Present

Rivers across the American West are under stress. Over time, human activities have decreased riparian vegetation and removed naturally occurring large wood from fallen trees and beaver dams. Overgrazing, wetland drainage, and artificial barriers like levees and berms have further changed these ecosystems, leaving behind simple channels that lack varied habitat for aquatic species.

Efforts to restore rivers have made some progress, but many projects are small in scale and focus more on reshaping the river rather than restoring the natural processes that keep it healthy. This study evaluates a different approach—Low-Tech Process-Based Restoration (LTPBR)—which works with nature to rebuild …

Environmental Movements In El Paso And Ciudad Juarez: Possibilities And Limitations Of Cross-Border Organization At The U.S.-Mexico Border, Vanessa Maria Almada

Open Access Theses & Dissertations

At the U.S.-Mexico border, the anthropogenic and nationalistic construction of the landscape has accelerated urbanization and unequal development without establishing effective binational institutions for governance over a shared commons. Borderlanders, then, contest unsustainable development with the added complexity of navigating a barrier which creates diverse socioeconomic and political realities that challenge cross-border cooperation. This qualitative research analyzes environmental organizations in El Paso and Ciudad Juarez. Through ethnographic study of mobilization in response to environmental legislation and administrative action in each city, the immediate barriers to cross-border cooperation and limitations of nationalistic institutions in the borderlands can be better understood.

A Systems Engineering-Based Method For Enabling Digital Transformation In A Binational Small Healthcare Enterprise, Manuel Adrian Alvarez Ramirez

Open Access Theses & Dissertations

The year 2020, often described as "the great accelerator" for emerging technologies, marked a period of significant transformation in lifestyles, work patterns, and business strategies. For instance, online meetings have become more convenient than in-person interactions, even with colleagues in neighboring offices. For small businesses, rapid regulatory and technological changes required swift adaptation, including the acquisition of new technologies, tools, and software to ensure survival. This transition also necessitated adopting indirect engagement, revising communication protocols, and digitally transforming information. Small and Medium-sized Enterprises (SMEs) in essential service sectors face also a fundamental paradox: their dependence on the skills, relationships, and …

U.S. Shareholder Activism: Convergence With Japan, Nobuhisa Ishizuka

Faculty Scholarship

To many observers long accustomed to slow, incremental change, the current boom in shareholder activism in Japan comes as a surprise. The opening for U.S.-style activists was created by market conditions that eventually resulted in policy changes that attracted significant numbers of foreign investors. However, even the current market would not have emerged without a parallel evolution in U.S. hedge-fund tactics, which gradually shifted over a number of years to a sophisticated and more nuanced approach, one based on partnership and dialogue with target companies, in contrast to adversarial relationships and public campaigns. This article attempts to place current trends …

Climate Vulnerability In Context: Interpretations Of Risk And Reality In Maine And New Hampshire, Sophie Hope Goodwin

Master's Theses and Capstones

This study examines the relationship between place-based climate vulnerability and belief in anthropogenic climate change in Maine and New Hampshire. While exposure-based models suggest that direct experience with environmental hazards should increase climate belief, sociological research emphasizes the role of political ideology and social context in shaping attitudes. Using county-level measures from the U.S. Climate Vulnerability Index combined with individual survey data from the Pine Tree State Poll and Granite State Poll, this study evaluates whether multidimensional climate vulnerability is associated with belief that climate change is happening now and is primarily caused by human activities. Results from three-step logistic …

Of Dunes And Ice: A Surface-Atmosphere Investigation Of Mars Co2 Sublimation Features And Titan Aeolian Fields, Racine D. Cleveland

Graduate Theses and Dissertations

This dissertation investigates a central question: How do planetary boundary layer processes manifest in observable surface geomorphology, and how can planetary imagery be used to quantify those effects? The planetary boundary layer (PBL) governs near-surface exchanges of momentum, heat, and volatiles, yet direct atmospheric measurements remain spatially and temporally limited on most planetary bodies. By analyzing geomorphic features preserved in high-resolution imagery, this work quantifies how boundary-layer processes leave measurable signatures on planetary surfaces. For Mars, high-resolution images from the Mars Reconnaissance Orbiter (MRO) HiRISE instrument were used to map CO2 sublimation features, or Swiss Cheese Features (SCFs), on the …

Geospatial Analysis Of The Influence Of Wastewater Disposal On The Induced Seismicity In Oklahoma, Usa, Kristine Nagy

Graduate Theses and Dissertations

Seismic records over the past decade and a half have indicated a significant increase of earthquakes in the state of Oklahoma and the evidence has strongly suggested the rise is likely caused by substantial wastewater disposal operations, a subsequent process of oil and natural gas extraction. This study investigated the relationship between wastewater disposal via injection wells, and its influence on inducing earthquakes in Oklahoma by employing Geographic Information System (GIS) tools for geospatial data integration and spatial analysis using United States Geological Survey (USGS) earthquake data and Underground Injection Control (UIC) Class II well data sourced from the Oklahoma …

Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri

Graduate Theses and Dissertations

This thesis examines how Arabic and English literary and intellectual traditions responded to the Black Death as a shared yet differently articulated experience of collective trauma. Drawing on trauma theory, particularly the work of Cathy Caruth and Dominick LaCapra, it analyzes how plague narratives function as cultural mechanisms for processing mass suffering. Through a comparative study of Arabic historiographical, theological, medical, and poetic texts alongside English allegorical, mystical, autobiographical, and satirical writings, this project argues that both traditions developed distinct narrative strategies to render the trauma of plague intelligible. Arabic plague literature, represented by figures such as Ibn Khaldūn, Ibn …

Old-Growth Surveys And Landowner Outreach In The Cross Timbers Of Oklahoma, Jon Webb

Graduate Theses and Dissertations

The Cross Timbers ecoregion represents a critical ecologic transition zone, spanning approximately 17 million acres across Oklahoma, Texas, Kansas, and Arkansas. Situated between eastern deciduous forests and the southern Great Plains, the Cross Timbers are dominated by drought-tolerant post oak (Quercus stellata) and blackjack oak (Quercus marilandica). Despite retaining some of the most extensive old-growth forests in the eastern United States, this ecoregion remains threatened by urban expansion, agricultural conversion, altered fire regimes, and eastern red cedar (Juniperus virginiana) encroachment. This project sought to identify, survey, and document large, previously un-surveyed or unreported tracts of old-growth Cross Timbers in Oklahoma, …

Groundwater Responses To Tidal Restoration At Pelican Marsh And Sea-Level Rise In Elkhorn Slough, California, Julie E. Nelson

Graduate Theses and Dissertations

Coastal wetlands represent a dynamic but vulnerable terrestrial-aquatic interface with future resilience controlled by historic hydrologic alterations, sea-level rise, and groundwater extraction. In diked coastal settings, poor tidal connectivity can degrade habitat from the impoundment of freshwater or hypersaline surface waters. Restoring tidal connectivity could foster marsh revitalization, but altering the surface hydrologic system could lead to unwanted salinity intrusion in shallow aquifers. Saline groundwater intrusion degrades freshwater quality and, while inevitable with sea-level rise, could be accelerated with tidal marsh restoration. To investigate this, I developed a steady-state groundwater flow model of Pelican Marsh, a diked, muted tidal marsh …

Examining Dei-Related Course Syllabi To Assess A College Library Collection: A Case Study, Amy P. Eklund, Joye Cauthen, Andres Cardona

Georgia Library Quarterly

This library collection development project identified courses in the college curriculum that had diversity, equity and inclusion (DEI)-related components and analyzed those courses' syllabi. The results of the project led to the addition of books to the collection that aligned with the library’s collection development policy and funding parameters. Other important outcomes included enhancements to catalog records and strengthened relationships with faculty. This strategy can be replicated to target other areas of study and help continuously develop a library collection.

Biodiversity Risk And Firm Valuation: Regional Heterogeneity And Value-Chain Exposure In Global Capital Markets, Madelein Wentzel

Doctoral Dissertations (DBA)

This study examines whether biodiversity-related risks are priced in global equity markets and whether that pricing varies across regions, using a cross-sectional sample of more than 10,000 globally listed firms with biodiversity and financial data drawn from the fourth quarter of 2025. Consistent with a regional heterogeneity hypothesis, the results show that biodiversity risk is significantly negatively associated with firm valuation in developed markets such as the United States and OECD countries, while the relationship is weaker, insignificant, or even positive in certain emerging regions including Latin America and the Middle East and Africa. The analysis further distinguishes between value-chain …

Good Life Automobility: Cultural/Rhetorical Resistance And Persistence Of Us Car Hegemony, Trinity O. Thompson

Department of Communication Studies: Dissertations, Theses, and Student Research

This project takes the car as a historical signifier of a rhetorical racialization process that enables a hypermobile white, masculine, neoliberal identity that pervades conceptions of mobility in the West. I locate these overlapping social formations under a cultural logic of good life automobility (GLA) that positions cars, a quintessential form of private property, as a motivator for a contemporary “good life” citizenship identity that cultivates neoliberal subjectivities of free movement and market consumption in contempt of socialized and racialized public transit futures. The introduction chapter elaborates on the boundaries of GLA while also contextualizing the two analysis chapters through …

Probing Representational Emergence In Large Language Models, Shawn Ismail

Master's Theses

This thesis investigates whether abrupt behavioral gains in large language models under scaling are accompanied by systematic changes in internal representations. It combines a behavioral screen of 65 tasks per family with targeted layerwise probing across eight decoder-only, open-weight model families. Behavioral emergence is defined for each family-task trajectory using an empirical jump detector, with segmented regression retained only as a diagnostic. The representational follow-up analyzes 27 selected MMLU subtasks shared across all families, spanning 37 checkpoints and 216 family-task units.

For each follow-up checkpoint, frozen linear probes are trained on every layer's hidden states to measure how much task-relevant …

Restorying The Reader: Adolescent Narratives Of Identity, Context, And Motivation, Jennifer R. Gardner

Dissertations

This present study examined how adolescents narrate their reading experiences and what those narratives reveal about reading identity, motivation, and engagement. This study responds to a persistent problem in literacy education: adolescent reading is often framed through disengagement or reduced to isolated constructs, while students’ lived reading experiences across school, home, digital, linguistic, and social contexts remain underexamined. Guided by Self-Determination Theory, Intersectionality, and Reader Response Theory, this study centers on adolescent voices and treats these participants’ stories as the primary avenue of understanding how they experience and interpret their reading lives and selves. Data were collected through narrative interviews, …

Chilling Or Galvanizing: Perceptions Of Controversial Issues In The Social Studies Classroom, Patrick Leahy

Dissertations

This study explores social studies teachers' perceptions of the use of controversial issues in their content and classrooms. Through a case study approach, it explores the decision-making process of social studies teachers in Georgia, contextualized by the current political environment, including the enactment of divisive concepts laws such as Georgia’s HB 1084, the Protect Students First Act, and increasing scrutiny over what is taught in public schools. Findings reveal that while the literature and advocates critical of divisive concepts laws tend to argue that these laws have a chilling effect on the discussion of controversial issues, the reality is more …

Exploring Agricultural Pathways: An Analysis Of Arkansas Community Colleges, Natasha Hightower

Graduate Theses and Dissertations

As demand for a highly skilled agricultural workforce continues to grow, Arkansas must strengthen accessible and clearly defined academic and career pathways to prepare future agricultural professionals. Community colleges serve as a critical entry point into higher education, particularly for rural and first-generation students, and play a vital role in both workforce development and transfer preparation. However, information related to agricultural education offerings, transfer pathways, and faculty at Arkansas community colleges is often decentralized and difficult for students and stakeholders to locate. The purpose of this study was to examine agricultural education offerings at community colleges in Arkansas, specifically agricultural …
