Molecular Dynamics Simulations of the Structure and Properties of Boron Containing Oxide Glasses: Empirical Potential Development and Applications
Authors:   , Deng Lu
Published: February 2025

Potential parameters that can handle multi-component oxide glass systems especially boron oxide are very limited in literature. One of the main goals of my dissertation is to develop empirical potentials to simulate multi-component oxide glass systems with boron oxide. Two approaches, both by introducing the composition dependent parameter feature, were taken and both led to successful potentials for boron containing glass systems after extensive testing and fitting. Both potential sets can produce reasonable glass structures of the multi-component oxide glass systems, with structure and properties in good agreement with experimental data. Furthermore, we have tested the simulation settings such as system size and cooling rate effects on the results of structures and properties of MD simulated borosilicate glasses. It was found that increase four-coordinated boron with decreasing cooling rate and system size above 1000 atoms is necessary to produce converged structure. Another application of the potentials is to simulate a six-component nuclear waste glass, international simple glass (ISG), which was for first time simulated using the newly developed parameters. Structural features obtained from simulations agree well with the experimental results. In addition, two series of sodium borosilicate and boroaluminosilicate glasses were simulated with the two sets of potentials to compare and evaluate their applicability and deficiency. Various analyses on the structures and properties such as pair distribution function, total correlation function, coordination number analysis, Qn distribution function, ring size distribution function, vibrational density of states and mechanical properties were performed. This work highlights the challenge of MD simulations of boron containing glasses and the capability of the new potential parameters that enable simulations of wide range of mixed former glasses to investigate new structure features and design of new glass compositions for various applications.
Catalysts of Women's Success in Academic STEM: A Feminist Poststructural Analysis
Authors:   , Mullet Dianna R.
Published: February 2025

This study analyzes senior women faculty's discourses about personal and professional experiences they believe contributed to their advancement in academic careers in science, technology, engineering, and mathematics (STEM). The purpose of the study is to understand factors that activate women's success in STEM disciplines where women's representation has not yet attained critical mass. A poststructuralist emphasis on complexity and changing nature of power relations offers a framework that illuminates the ways in which elite women navigate social inequalities, hierarchies of power, and non-democratic practices. Feminist poststructural discourse analysis (FPDA) methods allow analysis of women's talk about their experiences in order to understand the women's complex, shifting positions. Eight female tenured full professors of STEM at research-focused universities in the United States participated in the study. Data sources were in-depth semi-structured interviews, a demographic survey, and curricula vitae. Findings will help shape programs and policies aimed at increasing female representation and promoting achievement at senior levels in academic STEM fields.
The Impact of True Fit® Technology on Millennial Consumer Confidence and Satisfaction in their Online Clothing Purchase
Authors:   , Parr Jacqueline N.
Published: February 2025

This study examines the use of True Fit® technology by millennial consumers and its impact on consumer confidence and satisfaction with respect to online sizing. In the apparel industry, there is a lack of size standards among retailers, and as a result consumers will encounter frequent size variations in their clothing size. Difference sizing technology has been developed to address the sizing issue. One is True Fit® which unlike other sizing technologies, uses mathematical algorithms to compile large amounts of data from designers. The purpose of this study was to analyze consumer confidence and satisfaction after True Fit® has been used to make a sizing decision while online shopping. The technology acceptance model (TAM) was used as the basis for the theoretical framework for this study. TAM explores how current advances in technology are influencing consumers' behaviors and attitudes. The variables studies included perceived ease of use, perceived usefulness, attitude, intent to use True Fit®, confidence and satisfaction. The methodology used in the study is a quantitative method consisting of an online survey and a True Fit® task, where consumers were exposed to True Fit® prior to answering questions about the use of sizing technology. The results of the study suggest the dependent variable of confidence and satisfaction with the sizing technology was positively affected by the intent to use True Fit®. Thus, it can be inferred that consumers felt positively about adopting apparel size technology and that technology such as this would have wide application in the future.
To Intervene or Not to Intervene: How State Capacity Affects State Intervention and Communal Violence
Authors:   , Wilson Alexander C.
Published: February 2025

How does state capacity affect the state's ability to intervene in events of communal violence? Communal violence is conflict that occurs between two non-state groups that share a communal identity. The state controls the monopoly on the use of force, so it should be expected that the state will control these violent events. Research on intervention has shown that a state's military is an important indication of their ability to intervene. The study of other elements of state capacity such as the bureaucracy and political institutions have been largely ignored as factors to explain intervention. This paper builds on these elements of state capacity to argue that intervention can be explained by the state's military, bureaucracy, and the institutions that are in place. This argument has support from an empirical analysis conducted through replication data in Sub-Saharan Africa from 1989 to 2010.
Artificially Structured Boundary for Control and Confinement of Beams and Plasmas
Authors:   , Hedlof Ryan
Published: February 2025

An artificially structured boundary (ASB) produces a short-range, static electromagnetic field that can reflect charged particles. In the work presented, an ASB is considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. When used to create an enclosed volume, an ASB may confine a non-neutral plasma that is effectively free of applied electromagnetic fields, provided the spatial period of the ASB-applied field is much smaller than any one dimension of the confinement volume. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space-charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible. A classical trajectory Monte Carlo (CTMC) simulation suite has been developed in C++ to efficiently simulate charged particle interactions with user defined electromagnetic fields. The code has been used to explore several ASB configurations, and a concept for a cylindrically symmetric ASB trap that employs a picket-fence magnetic field has been developed. Particle-in-cell (PIC) modeling has been utilized to investigate the confinement of non-neutral and partially neutralized positron plasmas in the trap.
Same-Sex Parent Families in France: Past, Present, and Future
Authors:   , Griffin Janna Lee
Published: February 2025

This thesis contains four chapters. The first chapter gives an overview of the current situation concerning same-sex parent families in France. This involves discussions of the PACS (Pacte civil de solidarité), adoption, and marriage, as well as the societal influences that caused the massive negative response to the Taubira law. The second chapter goes into more detail concerning portrayals of homosexuality in French media throughout the years. There is a focus, however, on one of the earliest portrayals of lesbianism in French literature: The Nun by Diderot. Lastly, the third chapter involves further explanation of the history of homosexuality and same-sex parent families. This chapter explores these ideas specifically in the context of French history, as well as how conditions for same-sex parent families have changed in recent years. The fourth and final chapter presents conclusions of the research.
Exploring Food Security among Elderly Residents in Carrollton and Farmers Branch, Texas
Authors:   , Paschal Carla
Published: February 2025

Many senior citizens are surviving on minimal Social Security benefits and as a result, struggle with food security. Metrocrest Services in Farmers Branch, Texas, a suburb of Dallas, is a non-profit organization that provides several food programs to residents of the community including some programs that are specifically tailored to the needs of senior citizens. This project was to provide Metrocrest with an assessment of the food security of their senior clientele as well as other elderly residents of the Metrocrest service area and to evaluate the current senior focused programs. The project utilized qualitative research including both Metrocrest clients and residents who were not Metrocrest clients bot whose demographics were similar. The objectives were to determine the coping skills used by senior citizens in obtaining food, to assess seniors' awareness of the programs offered by Metrocrest, to discover barriers to accessing needed resources and to make recommendations of how programs could be improved or modified if needed. Through my research, I was able to present Metrocrest with a number of recommendations to improve their existing programs. I was also able to recommend some potential new programs that could be designed in conjunction with local senior centers to better serve the community.
In Vitro Exploration of Functional Acrolein Toxicity with Cortical Neuronal Networks
Authors:   , Durant Stormy R.
Published: February 2025

Acrolein is produced endogenously after traumatic brain injury (TBI) and is considered a primary mechanism for secondary damage occurring after TBI. We are using frontal cortex networks derived from mouse embryos and grown on microelectrode arrays in vitro to monitor the spontaneous activity of networks and the changes that occur after acrolein application. Networks exposed to acrolein exhibit a biphasic response profile. An initial increase in network activity, followed by a decrease to 100% activity loss in applications ≥ 50 µM. In applications below 50 µM, acrolein was not toxic but generated activity instability with coordinated but irregular population busts lasting for up to 6 days. The increase in activity preceding toxicity may be linked to a decrease in free spermine, a free radical scavenger that modulates Na+, K+, Ca+ channels as well as NMDA, Kainate, and AMPA receptors. Action potential wave shape analysis after 20 and 30 µM acrolein application revealed a concentration-dependent 15-33% increase in peak to peak amplitude within minutes after exposure. For the same concentrations of acrolein (50 µM), the time required to reach 100% activity loss (IT100) was longer in serum-free medium than in medium with 5% serum, in which IT100 values were reduced by a factor of 4. The greater toxicity in the presence of serum may be explained by acrolein adducts on serum proteins. These reaction products have been shown by other labs to be toxic in cell culture. This in vitro system could be used to expand biochemical analyses such as acrolein-induced spermine depletion and may provide an effective platform for investigating cell culture correlates of secondary TBI damage.
Urban Elementary School Students' Conception of Learning: A Phenomenographic Mapping of Variation
Authors:   , English Sherril H
Published: February 2025

For decades, urban public schools have been plagued by systemic and structural challenges that continue today. Scholars, policymakers, and the general public have pointed to problems of learning in urban schools and to low expectations for urban students' learning, but little attention has been given to how urban students themselves conceptualize learning. This study sought to fill the void by asking a group of urban students about their views of learning. A phenomenographic approach was employed to examine the qualitatively different ways in which 20 urban elementary fifth-grade students expressed their conceptions of learning and of their learning approaches. Consistent with phenomenography, the study was intended to understand the collective expressions of individuals' conceptions regarding a phenomenon, and emphasis was on the mapping of variation across the conceptions. Semi-structured interviews with open-ended questions, conducted individually, elicited the students' conceptions of the meaning of learning and their learning approaches. In a "search for meaning" approach, analyses were based on students' transcribed responses forming a pool of quotations. These quotations were divided first into "what" and "how" categories—"what" is learning and "how" does learning occur—and then into subcategories. The results were a set of categories organized in a two-level hierarchy. The three "what" conceptions were as follows: learning as increasing knowledge, learning as growing as a person, and learning as applying knowledge. The three "how" conceptions were the following: learning by persevering, learning by using active learning strategies, and learning by participating in social interactions. These conceptions comprised an outcome space representing the six different ways that these urban school students expressed their conceptions of learning inside and outside of school contexts. Whereas much attention in the educational literature has been directed to teachers setting high expectations for urban students, students in this study seemed to be setting high expectations for themselves, which included college and career. Although prior research has pointed to a need for urban students to develop more positive mindsets regarding engagement and motivation, students in this study tended to express some major metacognitive insights into their own learning. Educational implications are suggested based on the findings.
Effects of Bodily Arousal on Desire to Drink Alcohol among Trauma-Exposed Emerging Adult College Students
Authors:   , Kearns Nathan T
Published: February 2025

Alcohol consumption on college campuses is a major public health concern, particularly among emerging adults. Extant literature has identified trauma exposure and posttraumatic stress as robust risk factors for problematic alcohol use. However, the mechanisms underlying this association are less well-studied. Research indicates that bodily arousal is a fundamental feature of trauma exposure and posits that internal stimuli (e.g., heart pounding) at the time of trauma may manifest into conditioned cues that can trigger posttraumatic responding and related symptomatology, including alcohol use. However, past work supporting these assertions have used paradigms purposefully designed to evoke memories of the trauma, making it difficult to conclude whether the subsequent alcohol craving was due more to the explicit memory cue or the associated bodily arousal. The current study examined whether an implicit, trauma-relevant cue of bodily arousal (via hyperventilation) – independent of any explicit memory cue – would elicit increased desire to drink among 80 (Mage = 20.34; 63.8% female) trauma-exposed, emerging adult students. Results found no statistically significant difference in change in alcohol craving between the hyperventilation and control tasks. However, exploratory analyses indicated that trauma type (i.e., interpersonal/non-interpersonal) may moderate this relationship; more specifically, individuals reporting interpersonal trauma as their most traumatic event evidenced a significantly greater increase in desire to drink following hyperventilation compared to the non-interpersonal index trauma group. Generally, results suggest that bodily arousal, without an explicit trauma reminder, is not a specific and/or powerful enough trauma-relevant cue to reliably influence alcohol cravings across all trauma exposed emerging adult students. Suggestions for future directions to help in identifying at-risk subgroups, as well as methodological and procedural improvements, are discussed.
Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America
Authors:   , Johnson Barbara Ann
Published: February 2025

The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide, concluding that the potential for increased disparities as the aging population grows is very real and rural residents remain vulnerable to a poor(er) aging experience. Recommendations for policy and practice, as well as additional research, are made to address the conclusion.
John Ireland's Piano Sonata (1918-1920) and the Influence of Johannes Brahms
Authors:   , Su I-Shan
Published: February 2025

John Ireland is one of the most important British composers of the twentieth century. Many scholars believe the works of his early period were deeply influenced by Brahms. After graduating from the Royal College of Music, Ireland went on to develop a much more individual musical language, with influence from contemporary French composers. However, the young composer found himself confronted with the challenge of finding a new and personal style without turning wholly to impressionism or to chromaticism. In Ireland's Piano Sonata, Ireland adopted several of Brahms' compositional techniques. This piano sonata is an excellent example of one of Ireland's mature works that still demonstrates Brahms' influence.
Alloy Development and High-Energy X-Ray Diffraction Studies of NiTiZr and NiTiHf High Temperature Shape Memory Alloys
Authors:   , Carl Matthew A
Published: February 2025

NiTi-based shape memory alloys (SMAs) offer a good combination of high-strength, ductility, corrosion resistance, and biocompatibility that has served them well and attracted the attention of many researchers and industries. The alloys unique thermo-mechanical ability to recover their initial shape after relatively large deformations by heating or upon unloading due to a characteristic reversible phase transformation makes them useful as damping devices, solid state actuators, couplings, etc. However, there is a need to increase the temperature of the characteristic phase transformation above 150 °C, especially in the aerospace industry where high temperatures are often seen. Prior researchers have shown that adding ternary elements (Pt, Pd, Au, Hf and Zr) to NiTi can increase transformation temperatures but most of these additions are extremely expensive, creating a need to produce cost-effective high temperature shape memory alloys (HTSMAs). Thus, the main objective of this research is to examine the relatively unstudied NiTiZr system for the ability to produce a cost effective and formable HTSMA. Transformation temperatures, precipitation paths, processability, and high-temperature oxidation are examined, specifically using high energy X-ray Diffraction (XRD) measurements, in NiTi-20 at.% Zr. This is followed by an in situ XRD study of the phase growth kinetics of the favorable H-phase nano precipitates, formed in NiTiHf and NiTiZr HTSMAs, based on prior thermo-mechanical processing in a commercial NiTi-15 at.% Hf HTSMA to examine the final processing methods and aging characteristics. Through this research, knowledge of the precipitation paths in NiTiZr and NiTiHf HTSMAs is extended and methods for characterization of phases and strains using high energy XRD are elucidated for future work in the field.
The Population Genetic Structure of Quadrula aurea (Bivalvia: Unionidae), A Threatened Freshwater Mussel in Central Texas
Authors:   , Mabe Jeffrey A.
Published: February 2025

The anthropogenic alteration of riverine ecosystems has led to declines in the abundance and diversity of freshwater mussels (Bivalvia: Unionoida) worldwide. Central Texas is home to a diverse freshwater mussel fauna including three candidates for federal listing under the Endangered Species Act. Surveys conducted over the last few decades suggest many of the endemic freshwater mussel species in Texas exist in small isolated populations that may be vulnerable to the deleterious effects of genetic diversity loss. Microsatellite primers from two closely related species were used to identify a set of genetic markers that functioned in the Golden Orb (Quadrula aurea). Microsatellite markers were then applied to document the population genetic structure of Q. aurea within and among three connected river drainages in southeastern Texas. Gene flow within existing Q. aurea populations appears high indicating little potential for genetic issues stemming from isolation and inbreeding. Two weakly divergent admixed populations were identified occupying the San Antonio and Guadalupe/San Marcos rivers. Population genetic structure was related to river basin affiliation, but results for environmental factors were unresolved. Current effective population size estimates are large for the Guadalupe/San Marcos drainage and moderately large for the San Antonio drainage and there is no clear genetic evidence of contemporary population declines. Transport in the glochidial phase by a highly mobile host fish, the channel catfish (Ictalurus punctatus), may provide a mechanism for maintaining connectivity among spatially discrete mussel beds and deserves further study. Information on the occurrence and habitat associations of Q. aurea and two other threatened freshwater mussel species was documented. Quantification of the population genetic structure for Q. aurea provides important information needed for the management of this species, a baseline for understanding future changes, and insight into the factors that shape the population genetic structure of other threatened unionids in Texas.
Urban Trees as Sinks for Soot: Deposition of Atmospheric Elemental Carbon to Oak Canopies and Litterfall Flux to Soil
Authors:   , Rindy Jenna
Published: February 2025

Elemental carbon (EC), a product of incomplete combustion of fossil fuels and biomass, contributes to climate warming and poor air quality. In urban areas, diesel fuel trucks are the main source of EC emissions from mobile sources. After emission, EC is deposited to receptor surfaces via two main pathways: precipitation (wet deposition) and directly as particles (dry deposition). Urban trees may play an important role in removing EC from the atmosphere by intercepting and delivering it directly to the soil. The goal of this research was to quantify the magnitude of EC retention in leaf waxes (in-wax EC) and EC fluxes to the soil via leaf litterfall in the City of Denton, Texas. Denton is a rapidly growing urban location in the Dallas-Fort Worth metropolitan area. A foliar extraction technique was used to determine EC retention in leaf waxes. Foliar samples were collected monthly, from April through July, from pairs of Quercus stellata (post oak, n=10) and Quercus virginiana (live oak, n = 10) trees. Samples were rinsed with water and chloroform in a two-step process to determine EC retained in leaf waxes. A Sunset OC/EC aerosol analyzer was utilized to analyze the EC content of extracts filtered onto quartz-fiber filters. From April through July, leaf litter was collected bi-weekly under 35 trees (20 post oak, 15 live oak), and oven dried to determine dry weight. EC retained by tree canopies was estimated by multiplying in-wax EC by canopy leaf area index, while EC flux to soil was estimated by multiplying in-wax EC by leaf litterfall mass. This study shows that through retention of EC in leaf waxes, urban tree canopies represent important short-term sinks for soot in urban areas.
Effect of the Resistance Exercise-Induced Hormonal Changes on Satellite Cell Myogenic State
Authors:   , Luk Hui Ying
Published: February 2025

Skeletal muscle satellite cells are important for muscle repairing and muscle mass growth. For a successful muscle regenerative process, satellite cells have to sequentially undergoing different stages of myogenic process, i.e. proliferative state and differentiation state. To support this process, the presence of different circulating factors, such as immune cells, cytokines, and hormones, at the appropriate time course is critical. Among these factors, hormones, such as testosterone, cortisol, and IGF-1, have shown to play an important role in satellite cell proliferation and differentiation. Studies investigated the effect of testosterone on satellite cell using a supraphysiological dose in human or in cell culture demonstrated that testosterone is critical in satellite cell myogenic process. Due to the anabolic effect of testosterone on muscle, studies had been focused on the physiological means to increase the circulating testosterone concentration in the body to maximize the muscle mass growth from resistance exercise. The acute and transient increase in testosterone has shown to be beneficial to muscle mass growth and strength gain; however, this change in physiological testosterone concentration on satellite cell myogenesis is not known. Therefore the purpose of this dissertation is to first determine the effect of acute change in exercise-induced hormones on satellite cell myogenic state, then to determine if testosterone promotes satellite cell proliferation.

Published: February 2025

Human body is a complex system organized at different levels such as cells, tissues and organs, which contributes to 11 important organ systems. The functional efficiency of this complex system is evaluated as health. Traditional healthcare is unable to accommodate everyone's need due to the ever-increasing population and medical costs. With advancements in technology and medical research, traditional healthcare applications are shaping into smart healthcare solutions. Smart healthcare helps in continuously monitoring our body parameters, which helps in keeping people health-aware. It provides the ability for remote assistance, which helps in utilizing the available resources to maximum potential. The backbone of smart healthcare solutions is Internet of Things (IoT) which increases the computing capacity of the real-world components by using cloud-based solutions. The basic elements of these IoT based smart healthcare solutions are called "things." Things are simple sensors or actuators, which have the capacity to wirelessly connect with each other and to the internet. The research for this dissertation aims in developing architectures for these things, focusing on IoT-based smart healthcare solutions. The core for this dissertation is to contribute to the research in smart healthcare by identifying applications which can be monitored remotely. For this, application-specific thing architectures were proposed based on monitoring a specific body parameter; monitoring physical health for family and friends; and optimizing the power budget of IoT body sensor network using human body communications. The experimental results show promising scope towards improving the quality of life, through needle-less and cost-effective smart healthcare solutions.
A Foot in Two Worlds: Exploring Organizational and Professional Dual Identification
Authors:   , Ostermeier Kathryn
Published: February 2025

Who am I? Who are you? Who are we? These are some of the fundamental questions that identity scholars have grappled with since the 1900s when researchers across multiple disciplines first began to theorize about the self, identity, and identification. While the benefits and consequences of singular identities has been largely studied, recent scholars have argued for the importance of multiple identity research, as multiple identities have become increasingly salient to individuals due to societal and organizational changes including globalization and technological advancements. An important phenomenon within multiple identity research is dual identification, of which I explore a specific type– identification with both one's organization and one's profession. Using a three-study, quantitative design spanning two industries, I studied the effects of dual identification and identity conflict on individual psychological outcomes, turnover intentions, and OCB engagement. Findings from these three studies, holistically, indicate that when individuals experience identity conflict between their organizational and professional identities, they experience negative outcomes. These negative outcomes – increased emotional exhaustion, psychological distress, and turnover intentions, in addition to reduced OCB engagement – have important ramifications for the individuals themselves and their organization. However, post-hoc results indicate that dual identification – through the main effects of organizational and professional identification – itself leads to positive outcomes. Thus, whether multiple identities are a boon or burden might be a result of whether an individual has reconciled these identities. Ultimately, this research adds to the identity literature by providing a more nuanced view of multiple identities and their outcomes.
Student Perceptions of the University of North Texas Campus Police
Authors:   , Stidd Megan D
Published: February 2025

Numerous studies have been conducted to determine predictors of perceptions and attitudes toward police. Less effort has been spent on determining university and college students' perceptions of campus police departments. The purpose of this thesis was to fill this gap in the literature with an added emphasis on exploring potential differences in perceptions between students involved in Greek Life organizations and students not involved in Greek Life organizations. Prior literature found that Greek Life students engage in risk-taking behaviors at higher rates than their counterparts, so it was hypothesized that Greek Life students would have higher levels of distrust in the campus police due to their increased engagement in risk-taking behaviors. The survey questionnaire measuring trust and procedural justice/legitimacy perceptions of campus police was distributed through convenience sampling to university students. Descriptive statistics, bivariate analyses, and multivariate analyses were utilized to analyze the data. The results showed that students overall had positive perceptions of campus police, that Greek Life students had more negative perceptions of the campus police than non-Greek Life students, and that students with prior interactions with the campus police were more likely to perceive the police to be less procedurally just/legitimate. Race/ethnicity was not found to be a predictor in perceptions of trust or procedural justice/legitimacy of the campus police. Limitations, policy implications, and suggestions for future research concerning student perceptions of campus police were also discussed.
Seeds of Disempowerment: Bt cotton and Accumulation by Dispossession in the States of Maharashtra, Telangana, and Andhra Pradesh in India
Authors:   , Hoyt Andrew
Published: February 2025

In 1991, India adopted neoliberalism, a system of political economic practices that promotes private property and free trade, as its political and economic system to promote development in their country. India's neoliberal reform has created issues surrounding human development, resource accumulation, and power struggles. Eleven years later, in 2002, Bt cotton was introduced to the Indian agricultural sector. This research examines how the genetically modified organism Bt cotton is being used to commodify nature in the context of agriculture under neoliberalism. The research focuses on the dispossession of the rural farmers through the commodification of agriculture using Bt cotton. Dispossession of the rural farmers happen through the implications that arise from the commodification of nature. Through Marxist theory of primitive accumulation, this research analyzes accumulation by dispossession and how it neglects the working class and its struggle in rural India. Through this examination, the research will argue alternatives to the dispossession of the working class and the commodification of nature through Bt cotton. Dispossession, in this research, is examined both through working class, but also through the dispossession of biodiversity. Through the loss of biodiversity, the rural farmers are becoming dispossessed from a more sustainable environment. Along with these goals, the research will also incorporate themes of food security through changing landscape of agriculture due to the incorporation of Bt cotton. This research argues the contradictions that are presented through the commodification of agriculture under neoliberalism and provide a contribution to social justice literature, and our understanding of the relationship between technology and the commodification of nature.
Comparison of Heterogeneity and Heterogeneity Interval Estimators in Random-Effects Meta-Analysis
Authors:   , Boedeker Peter
Published: February 2025

Meta-analyses are conducted to synthesize the quantitative results of related studies. The random-effects meta-analysis model is based on the assumption that a distribution of true effects exists in the population. This distribution is often assumed to be normal with a mean and variance. The population variance, also called heterogeneity, can be estimated numerous ways. Accurate estimation of heterogeneity is necessary as a description of the distribution and for determining weights applied in the estimation of the summary effect when using inverse-variance weighting. To evaluate a wide range of estimators, we compared 16 estimators (Bayesian and non-Bayesian) of heterogeneity with regard to bias and mean square error over conditions based on reviews of educational and psychological meta-analyses. Three simulation conditions were varied: (a) sample size per meta-analysis, (b) true heterogeneity, and (c) sample size per effect size within each meta-analysis. Confidence or highest density intervals can be calculated for heterogeneity. The heterogeneity estimators that performed best over the widest range of conditions were paired with heterogeneity interval estimators. Interval estimators were evaluated based on coverage probability, interval width, and coverage of the estimated value. The combination of the Paule Manel estimator and Q-Profile interval method is recommended when synthesizing standardized mean difference effect sizes.
The Biogeographic Distribution of Caddisflies (Insecta: Trichoptera) within the South-Central United States
Authors:   , Perry Heather Ann
Published: February 2025

Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.
Searching for Songs of the People: The Ideology of the Composers' Collective and Its Musical Implications
Authors:   , Chaplin-Kyzer Abigail
Published: February 2025

The Composers' Collective, founded by leftist composers in 1932 New York City, sought to create proletarian music that avoided the "bourgeois" traditions of the past and functioned as a vehicle to engage Americans in political dialogue. The Collective aimed to understand how the modern composer became isolated from his public, and discussions on the relationship between music and society pervade the radical writings of Marc Blitzstein, Charles Seeger, and Elie Siegmeister, three of the organization's most vocal members. This new proletarian music juxtaposed revolutionary text with avant-garde musical idioms that were incorporated in increasingly greater quantities; thus, composers progressively acclimated the listener to the dissonance of modern music, a distinctive sound that the Collective hoped would become associated with revolutionary ideals. The mass songs of the two Workers' Song Books published by the Collective, illustrate the transitional phase of the musical implementation of their ideology. In contrast, a case study of the song "Chinaman! Laundryman!" by Ruth Crawford Seeger, a fringe member of the Collective, suggests that this song belongs within the final stage of proletarian music, where the text and highly modernist music seamlessly interact to create what Charles Seeger called an "art-product of the highest type."
The Role of Mobile Homes in Migration from Mexico to Central North Carolina
Authors:   , Kiesewetter Kimberly Ann Cochran
Published: February 2025

A key consideration in the human migration process to a destination country is the need to secure suitable and affordable housing. As housing costs have increased in the United States in recent decades, mobile homes – also known as manufactured housing or "trailers" – have become a significant source of affordable housing for people living in the United States. In rural communities, mobile homes have become a substantial portion of the available housing stock. This research project explored mobile home living specifically in relation to Mexican migrants who lived in a rural county in central North Carolina. Consideration was given to the practical issues of this type of housing, as well as any influence the American stigma of mobile homes might have had on the ways people experienced their homes and communities.
Original Viola Study Literature: Analyzing the Pedagogical Contributions of Marco Frank
Authors:   , Salinas Ashley
Published: February 2025

Viola pedagogy has historically been closely intertwined with and highly dependent upon violin repertoire. As the viola emerged as an instrument worthy of independent study, many still rely on transcriptions of violin etudes. Fortunately, the efforts of performers, teachers, and scholars have brought forth discoveries of original viola literature and thus shifted toward the perception that viola should begin to embrace its individual pedagogy. Viennese composer and violist Marco Frank contributed three volumes of Viola-Etuden and a method book, Praktische Viola-Schule, which are suitable for the intermediate violist. This document explores and analyzes the usefulness of an original viola series in comparison to the ‘tried and true' violin transcriptions.
A Performance Guide to Se Enkhbayar's Choral Tone Poem Önchin Botog (A Lonely Baby Camel) for SATB Soloists and SATB Chorus (with Divisions) A Cappella
Authors:   , Lin Pei-Chi
Published: February 2025

Se Enkhbayar (b. 1956) is one of the most important contemporary Mongolian composers in China. His choral tone poem, Önchin Botog, integrates the traditional Mongolian musical elements Urtiin Duu (long song) and Khöömii (throat singing) with modern choral music and is one of the most representative works in the genre of modern Mongolian choral music. The purpose of this study is to provide a performance guidance for non-Mongolian musicians on Se Enkhbayar's work, Önchin Botog, by presenting his biographical and cultural backgrounds, discussing the use of traditional Mongolian singing styles, special rhythmic patterns (horse-step rhythm) and Chinese pentatonic scales. For conductors, this guide can shorten preparation time by providing musical analysis for artistic interpretation and practical points for sound effect creation. For solo singers, this guide will enable a Bel Canto singer to sing Urtiin Duu in Mongolian singing style. For Khöömii singers, this guide provides supplementary practical suggestions.
Naples and the Emergence of the Tenor as Hero in Italian Serious Opera
Authors:   , Ekstrum Dave
Published: February 2025

The dwindling supply of castrati created a crisis in the opera world in the early 19th century. Castrati had dominated opera seria throughout the 18th century, but by the early 1800s their numbers were in decline. Impresarios and composers explored two voice types as substitutes for the castrato in male leading roles in serious operas: the contralto and the tenor. The study includes data from 242 serious operas that premiered in Italy between 1800 and 1840, noting the casting of the male leading role for each opera. At least 67 roles were created for contraltos as male heroes between 1800 and 1834. More roles were created for tenors in that period (at least 105), but until 1825 there is no clear preference for tenors over contraltos except in Naples. The Neapolitan preference for tenors is most likely due to the influence of Bourbon Kings who sought to bring Enlightenment values to Naples. After the last castrato retired in 1830 and the casting of contraltos as male heroic leads falls out of favor by the mid-1830s, the tenor, aided by a new chest-voice dominant style of singing, becomes the inheritor of the castrato's former role as leading man in serious Italian opera.
Estrategias Didácticas para la Enseñanza del Enfoque Léxico y las Nuevas Tecnologías de la Información y de la Comunicación (TIC) en la Clase de Español como Lengua Extranjera (ELE)
Authors:   , Reed Stella L

The purpose of this research was to use a lexical approach, and information and communication technologies (ICT) as strategies to facilitate learning to students of Spanish as a foreign language, to answer the research questions: (1) if the use of multiword lexical units improves the lexical competence and (2) whether the use of technology is an effective strategy to facilitate learning. A lesson plan with different activities was designed and put into practice with two groups of students (experimental and control) of the intermediate level of the University of North Texas (UNT). The collected data were analyzed using the quantitative paradigm with the variance model ANOVA with repeated measures, and the qualitative or interpretive paradigm to offer a broader perspective of the learning process of multiwords lexical units (collocations and idiomatic expressions). The results of this investigation answered the research questions and confirmed the effectiveness of the lexical approach and ICT in the teaching-learning process and facilitated the student's acquisition of L2.

Computational Investigation of DNA Repair Enzymes: Determination and Characterization of Cancer Biomarkers and Structural Features
Authors:   , Silvestrov Pavel
Published: February 2025

Genomic integrity is important for living cells' correct functioning and propagation. Deoxyribonucleic acid as a molecule is a subject to chemical reactions with agents that can come from environment as well as from internal metabolism processes. These reactions can induce damage to DNA and thus compromise the genetic information, and result in disease and death of an organism. To mitigate the damage to DNA, cells have evolved to have multiple DNA repair pathways. Presented here is a computational study of DNA repair genes. The structure of the Homo sapiens direct DNA repair gene ALKBH1 is predicted utilizing homology modeling methods and using AlkB and DBL proteins as templates. Analysis of the obtained structure and molecular dynamics simulations give insights into potentially functionally important residues of the protein. In particular, zinc finger domains are predicted, and lysines that could perform catalytic activities are investigated. Subsequent mutagenesis experiments revealed the effect of the residues predicted to form zinc fingers on activity of ALKBH1. Structure and dynamics of AlkD, a Bascillus cereus base excision DNA repair protein is also studied. This protein has been shown to bind DNA with large alkyl adducts and perform excision catalysis without base flipping which is characteristic to other enzymes in the same family. MD simulations of AlkD revealed that B helix, which interacts with DNA, has higher fluctuations when AlkD is not bound to DNA, and thus could have a role in binding and recognition of DNA. For the purpose of finding biomarkers and to further our understanding of a mode of action of DNA repair genes, statistical methods were applied to identify mutations that are linked to cancer phenotypes. Analysis was based on case-control studies of patients with cancers of prostate, breast, pancreas, lung as well as chronic lymphocytic leukemia from NCBI dbGAP database. Those mutations that result in missense mutations were further investigated. In particular, extensive MD simulations and experimental investigations were performed on the mutation in the ALKBH7 gene that was found to be linked to prostate cancer.
Orchestral Excerpts for Conductors

Published: February 2025

"Orchestral Excerpts for Conductors" is a compilation of sixty-five full score excerpts from the orchestral repertory arranged for string quartet and piano. The purpose of this collection is to provide conducting students with a pedagogical resource for learning how to handle technically challenging excerpts in orchestral music. This dissertation serves as a plan for the final publication of the excerpts book; while it includes the full score excerpts, it does not include the arrangements for string quartet and piano.
