Evaluating Nutrient Uptake Efficiency Of Texas Native Plants In Simulated Constructed Wetland Systems, Angelica Canizalez

Water Resources Science and Technology Theses and Graduate Research Reports (Archived)

Nutrient enrichment from wastewater effluent and runoff is a major driver of eutrophication in freshwater systems, increasing the need for effective and ecologically beneficial treatment strategies. Constructed wetlands (CWs) offer a nature-based solution for reducing nitrogen (N) and phosphorus (P) while simultaneously supporting habitat and biodiversity. However, most CW research has focused on traditional species such as cattails and bulrushes, with limited quantitative data on the performance of Texas native plants. This study evaluated the nutrient uptake potential and stress tolerance of two Texas native species—buttonbush (Cephalanthus occidentalis) and Maximilian sunflower (Helianthus maximiliani)—in simulated, recirculating wetland systems.

Data from nearby monitoring stations containing various water quality parameters typically associated with produced water, including total dissolved solids (TDS), chloride (Cl), sulfate (SO4), and specific conductance was used to perform a statistical analysis of spatial and temporal trends. Spatial comparisons were made between both sites and upstream, tributary, and downstream roles to test for variances in water …

Defining The Causal Contribution Of The Gut Microbiota To Cardiomyopathy Pathogenesis As A Basis For Developing Microbiome-Targeted Therapies, Xu Shi

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Heart failure (HF) is a leading cause of morbidity and mortality worldwide, placing substantial clinical and economic burdens on society. Although advances in therapy have improved patient outcomes, the biological mechanisms that drive HF onset and progression remain incompletely understood. Increasing evidence suggests that the gut microbiota, the trillions of microorganisms residing in the gastrointestinal tract, plays a key role in some forms of heart disease, especially cardiovascular disease. Moreover, gut microbial dysbiosis has been associated with systemic inflammation, metabolic imbalance, and immune dysregulation, all of which contribute to the pathophysiology of HF. Cardiomyopathy, a primary disorder of the heart …

Dolphins ‘Orient-Against-Current’: Foraging In Dredged Channels, Eliza M.M. Mills, Sarah Piwetz, Dara N. Orbach

Marine Science

Bottlenose dolphins (Tursiops sp.) are opportunistic foragers with global distributions that utilize diverse feeding tactics based on environmental factors, habitat features, prey behavior, group dynamics, and genetics. We describe a unique foraging tactic regularly observed in the confluence of dredged shipping channels with high anthropogenic disturbance, and explore potential abiotic (temporal, tidal, habitat) drivers of the behavior. A shore-based digital theodolite was used from 2021 to 2022 to observe common bottlenose dolphins (T. truncatus) foraging within a current in a technique we term Orient-Against-Current (OAC). During OAC, dolphins position themselves facing into the flow of a current, swimming at a …

June 30, 2023: Resurrections And Bad Omens Of A Nadir Court, Zamir Ben-Dan

UC Law Constitutional Quarterly

June 29, 2023 was monumental for racial justice advocates and scholars; the U.S. Supreme Court issued a major decision that eviscerated affirmative action while declaring itself a vanguard of racial equality. The Court’s race-related juridical activities on the following day, June 30th, received far less attention. On June 30, 2023, the Court denied certiorari in five cases directly implicating race. Those denials of certiorari generated five opinions, two concurring in the denial and three dissenting from denial. These five opinions should have created as much buzz as the Court’s affirmative action decision the day prior; examined together, they tell a …

The Role Of Procedural Due Process In Equal Protection And Affirmative Action Analysis: The Narrowly Tailored Prong, Simona Grossi

UC Law Constitutional Quarterly

The Supreme Court’s decision in Students for Fair Admissions v. Harvard College marked the end of affirmative action as traditionally practiced in higher education admissions, forcing universities to seek alternative legal pathways for fostering diversity. At the same time, the Trump administration’s executive orders targeting DEI initiatives have exacerbated the legal uncertainty, raising critical questions about how institutions can preserve fairness in admissions while withstanding both judicial and political scrutiny.

This article argues that Procedural Due Process—when read in conjunction with Equal Protection—provides a constitutionally sound and structurally fair framework for admissions policies that align with strict scrutiny while preserving …

Southern / Appalachian Migrants And Urban Development Politics In Uptown Chicago, 1950-1972, Charles Wayne Dowdy

Electronic Theses and Dissertations

This thesis investigates how ideas of interregional migration were used in service of urban renewal agendas in Uptown Chicago from 1950 to 1972. It argues that The South and Appalachia as regional ideas were impactful in postwar midwestern urban development politics, even as regional identity was less powerful as an adhering force for actual migrants in comparison with factors of race and class. Chapter 1 examines the development and use of the urban enclave model of interregional migration by the Uptown Chicago Commission in the late 1950s. It argues that anxieties around suburbanization and urban decline fueled the production of …

Beyond The Surface: Exploring The Experiences Of Black Female Athletes At Power 4 Institutions, Michonné Leatrice Gamble-Rivers

Participants included 22 students from two accredited high schools in Mississippi, one fully online and one traditional brick-and-mortar school, both of which offered asynchronous social studies courses approved by the state …

Knowing One's Place At The Table: Taste As A Means Of Othering In The American Colonies, 1700-1775, Nicholas Harp

Master's Theses or Doctor of Nursing Practice

This thesis began as an inquiry into a simple question. How did people in the American colonies talk about the food that they ate? This question led to a fascinating look into the social dynamics of the people living in eighteenth century America. Their own personal writings demonstrate how they understood their place in society through the food that they ate. Moreover, they often wrote about the way that other people ate in ways that alienated or discriminated against different ethnic groups. A look into the secondary historiography revealed that other historians had noticed this trend. However, very few addressed …

The Relationship Between Exercise And Prospective Memory: A Meta-Analysis, Shaykhah Salman Alqahtani

Electronic Theses and Dissertations

The comorbidity of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is well documented and associated with elevated risk of aggression and suicidality among certain populations. However, no research to date has examined these associations among adolescents. Using data from the National Comorbidity Survey-Adolescent Supplement (NCS-A), the present study examined whether the presence of AUD was associated with greater outward aggression, suicidal ideation, and attempts, and whether these associations differed across race/ethnicity, in a weighted sample of 737,996 adolescents with PTSD (10.3% Hispanic, 16.4% Black, 73.3% White). AUD presence was significantly associated with higher odds of breaking items, attacking …

A Road Less Traveled: Exploring The Motivators Influencing College Enrollment Decisions Among Youth Who Have Experienced Foster Care, John William Blue

Electronic Theses and Dissertations

Youth who have experienced the foster care system are an underserved student population in higher education. While higher education is an important pathway to upward mobility and civic participation, foster youth consistently face systemic barriers such as unstable placements, limited financial resources, and a lack of consistent adult guidance, resulting in significantly lower rates of college enrollment and degree attainment compared to their peers (Courtney & Okpych, 2020; Salazar, 2013). This three-manuscript dissertation investigates the challenges that youth who have experienced foster care face and the factors that influence them to pursue enrollment in four-year universities in Illinois, while also …

The Lived Experiences Of Lgbtq+ Individuals Living In Male Residential Spaces In The South, Bri Reda

Electronic Theses and Dissertations

While LGBTQ+ visibility on college campuses has increased, LGBTQ+ students still report negative experiences, particularly in residential environments where harassment and unwelcoming attitudes are common (Kortegast, 2017; Pryor, Ta, & Hart, 2016). Previous studies have shown that LGBTQ+ individuals often conceal their identities in residence halls due to discomfort, further diminishing their feelings of safety and connection to the campus community (Blakmon, O’Hara, & Viars, 2020; Pryor, Ta, & Hart, 2016). Despite efforts to implement inclusive policies, little research has explored the experiences of LGBTQ+ individuals in male-assigned residence halls, especially in states like Mississippi with gender-segregated housing requirements (Mississippi …

Reading Teacher Perceptions: The Impact Of Educator Preparation Program Literacy Coursework And Clinical Experiences On Teacher Efficacy In Historically Underrepresented Populations, Emily Taubken

Electronic Theses and Dissertations

Despite research that indicates the critical importance and lifelong impact of early reading proficiency for students, national reading proficiency trends demonstrate most students in the United States are not yet reading at grade level, with disparities existing among historically underrepresented subgroups. Additionally, research shows that preservice and in-service teachers have documented limited feelings of self-efficacy in teaching reading specifically, suggesting limitations in preservice training for educators. To better understand how reading teachers perceive the efficacy of their preservice teacher academic and clinical experiences, especially for those who serve historically underrepresented student populations, this study seeks to document the perspectives of …

Knowledge Acquisition On Mass-Shooting Events Via Llms For Ai-Driven Justice, Benign Ihugba

All Theses

Mass-shooting events pose a significant challenge to public safety because they generate large volumes of unstructured textual data, making it difficult to conduct effective investigations and formulate public policy. The proposed knowledge acquisition system utilized Large Language Models (LLMs) with few-shot prompting to extract vital information from news articles, police reports, and social media content at high speed. The system used entity recognition to detect vital information, which included offenders, victims, locations, and criminal instruments that support legal investigations.

Individual, Family, and Community Education ETDs

This study examines: relations between maternal parenting stress in infancy and preschool-aged children’s internalizing and externalizing symptoms; whether verbal and physical harsh parenting practices mediate these relations; and whether these relations are moderated by child gender. Research links maternal parenting stress to harsh parenting, which is a risk factor for children’s internalizing and externalizing symptoms. But limited research has examined how maternal stress in infancy affects preschool-aged children’s outcomes, or how verbal and physical harsh parenting practices independently affect these outcomes. The study data came from the Future of Families & Child Wellbeing Study. Results indicate maternal parenting stress in …

Distributed Agency And Posthuman Rhetoric In Genai-Assisted First-Year Composition Writing, Bianca E. Guzman

English Department Theses

This thesis explores the dynamic interaction between human and non-human agents in the process and production of writing. In particular, theories on the co-constitutive nature of the human-technological relationship, posthumanist theory, and rhetorical theory are used to reframe first-year writing as an act of distributive agency that always involves people, objects, and their material environments. In recognizing the essential role of “things” in first-year writing, this thesis considers how Generative Artificial Intelligence (GenAI) can be critically conceptualized and utilized as a pedagogical tool by instructors in the college writing classroom. Additionally, this thesis details an IRB-approved research study done at …
