Studying the Impact of a Summer Training Course on Teacher Ability to Use and Integrate an Innovative Online Museum Curriculum in Secondary Schools
Authors:   , Preusse David N.
Published: February 2025

This study seeks to answer the overarching question of how the use of a digitally delivered arts curriculum, including a virtual museum environment, affects teacher's perceptions of curriculum integration and whether they believe it is successful in the classroom. This study is based on the analysis of archival data collected during a pilot study that was conducted in the fall of 2016 and spring of 2017. This pilot study used a qualitative, descriptive approach and included the use of surveys, interviews, focus groups, and observations. The main focus of this study was on the experiences of a selection of educators who took part in the pilot study and summer training sessions to determine the successes and challenges they faced as they sought to the implement the experimental digitally delivered arts curriculum. The results of the study should improve the field's understanding of how virtual environments and technology can influence teacher experiences and perceptions of their potential value for learning as they continue to take hold in public schools worldwide.
Desire Lines: Dérive in Heterotopias
Authors:   , Snider Jesse Rhea
Published: February 2025

This study provides an examination and application of heterotopic dérive, a concept that combines spatial theories originated by Foucault and psychogeographical methods advocated by the Situationists, as enacted within theatrical performance spaces. The first chapter reviews theories related to space, place, and heterotopias, as well as the psychogeographical methods of the Situationists, particularly the dérive. The literature review is augmented with accounts of my experiences of serendipitous heterotopic dérive over a period of several years as a cast member in, or a technical director for, theatrical productions in the Department of Communication Studies Black Box Theatre. Based on the review, I postulate that heterotopic dérive is a potentially valuable phenomenon that performance studies scholar/artists can utilize consciously in the rehearsal process for mounting theatrical performances. To test this proposition, I worked collaboratively with a theatrical cast to craft a devised performance, Desire Lines, with a conscious effort to engender heterotopic dérive in the process of creating the performance. This performance served as the basis for the second chapter of the study, which analyzes and discusses of the results of that investigation. This project enhances understanding of the significance of the places and spaces in which performers practice their craft, and argues for the potential of recognizing and utilizing the agency of heterotopic spaces such as the Black Box.
Humility and Attachment Style in Adult Romantic Relationships
Authors:   , Farrell Jennifer Ellen
Published: February 2025

The goal of this study was to investigate the relationship between adult attachment style, humility, and relationship satisfaction in college student couples. Attachment style--given its significant role in predicting how individuals feel, think, and behave in relationships--was expected to be an important predictor of humility, although this possibility has rarely been studied empirically. The current study found that: (a) attachment anxiety and attachment avoidance were significant, negative predictors of total humility, (b) attachment anxiety (but not attachment avoidance) was a significant, negative predictor of both intrapersonal and interpersonal humility, (c) a romantic partner's attachment avoidance (but not attachment anxiety) was a significant, negative predictor of a target person's relationship satisfaction, and (d) a romantic partner's perceived level of humility was a significant, positive predictor of a target person's relationship satisfaction.
Health Disparities among Sexual Minorities: Trends of Health Care and Prevalence of Disease in LGB Individuals
Authors:   , Villarreal Cesar
Published: February 2025

The primary focus of the current study was to identify health disparities between sexual minority subgroups by examining differences of health indicators in lesbians, gay men, and bisexual individuals, and compare these to their heterosexual counterparts. Data was drawn from the National Health and Nutrition Examination Survey (NHANES), and variables examined in sexual minorities were related to health care access and utilization, risky health behaviors, and overall disease prevalence and outcomes. Findings suggest there are still some current health disparities in terms of insurance coverage, access to medical care, substance use, and prevalence of certain health conditions. However, a trend analysis conducted to examine three NHANES panels, suggests a mild improvement in some of these areas. Further findings, discussion, limitations of the study, current implications, and future directions are addressed.
"When We Go to Deal with City Hall, We Put on a Shirt and Tie": Gay Rights Movement Done the Dallas Way, 1965-2003
Authors:   , Wisely Karen S.
Published: February 2025

This dissertation examines the gay rights movement occurring in Dallas, Texas, from the mid-twentieth century to present day by focusing on the work of the Dallas Gay and Lesbian Alliance (DGLA), previously known as the Dallas Gay Political Caucus and the Dallas Gay Alliance. Members of that group utilized a methodology they called "the Dallas Way" that minimized mass protests and rallies in favor of using backroom negotiations with the people who could make the changes sought by the movement. The fact that most of the members of the DGLA were white, professional men aided in the success of their methodology. Particularly useful in this type of effort is the use of legal action. The Dallas community supported several lawsuits that attempted to overthrow various versions of sodomy laws in the Texas Penal Code that criminalized an entire population of gay men and lesbians in the state.
Membrane-Based Energy Recovery Ventilator Coupled with Thermal Energy Storage Using Phase Change Material for Efficient Building Energy Savings
Authors:   , Mohiuddin Mohammed Salman
Published: February 2025

This research work is focused on a conceptual combination of membrane-based energy recovery ventilator (ERV) and phase change material (PCM) to provide energy savings in building heating, ventilation & air-conditioning (HVAC) systems. An ERV can recover thermal energy and moisture between the outside fresh air (OFA) entering into the building and the exhaust air (EA) leaving from the building thus reducing the energy consumption of the HVAC system for cooling and heating the spaces inside the building. The membranes were stacked parallel to each other forming adjacent channels in a counter-flow arrangement for OFA and EA streams. Heat and moisture is diffused through the membrane core. Flat-plate encapsulated PCM is arranged in OFA duct upstream/downstream of the ERV thereby allowing for further reduction in temperature by virtue of free cooling. Paraffin-based PCMs with a melting point of 24°C and 31°C is used in two different configurations where the PCM is added either before or after the ERV. Computational fluid dynamics (CFD), and heat and mass transfer modeling is employed using COMSOL Multiphysics v5.3 to perform the heat and mass transfer analysis for the membrane-based ERV and flat-plate PCMs. An 8-story office building was considered to perform building energy simulation using eQUEST v3.65 from Department of Energy (DOE). Based on the heat and mass transfer analysis, it is found that the sensible effectiveness (heat recovery) stood in the range of 65%-97% while the latent effectiveness (moisture recovery) stood at 55%-80%. Also, the highest annual energy savings achieved were 72,700 kWh in electricity consumption and 358.45 MBtu in gas consumption.
The Double Down: The Autoethnography of Navigating as Black American Male Instructing Preservice Teachers Methods of Teaching Social Studies

Published: February 2025

This inquiry is an autoethnography of my experiences as a Black American male serving as a methods of social studies instructor to preservice teachers. Although some may deem this study as subjective, I have embraced that designation to provide insider information to others that face intersectionality and to inform institutional practices in teacher education programs.
The Construction of Identity through Early Childhood Curriculum: Examining Picturebooks from a Critical Feminist Lens
Authors:   , Medellin Kelly
Published: February 2025

Picturebooks are an important part of the classroom environment in early childhood education. They open doors to new experiences, nurture students' cultural identities, and invite students to explore connections across cultures. In the United States today, many of the picturebooks that are available to teachers and students in preschool classrooms come from the state curriculum that the school district has implemented. Shifting demographic trends have led many educators to recognize a need for more diversity of literature in classrooms. This study was conducted in response to this growing concern that books should better reflect the cultures and identities of the children who read them, with a particular emphasis on young female children of color. The research question guiding this study is: How do picturebook texts and illustrations in an early childhood curriculum represent the identities of female characters of color as viewed through a critical feminist theoretical lens? To investigate this question, I critically analyzed children's picturebooks from a current early childhood curriculum adopted by the state of Texas, focusing on representations of gender and race. The selected books were analyzed using critical content and critical visual analyses to consider how the text and illustrations together represent female characters of color. Although earlier studies of picturebooks have pointed out a deficit of authentic portrayals of female characters of color, this study found that books in the sample did show some attention to authentic cultural themes including motherhood, action and agency, and subjugated knowledge and culture. However, implications for practice and research included the need for more balanced representation of diverse cultures within the curriculum to better reflect preschool demographics, as well as the need for more classroom instruction on books that give voice and agency to young female children of color as they develop their personal and cultural identities.
A Detailed Investigation, Comparison, and Analysis of the Practice Habits of Undergraduate Vocal and Piano Performance Majors
Authors:   , Radziun Barrett
Published: February 2025

For musicians of all kinds, practice is an essential component in establishing and refining their skills. How a musician learns the art of practicing, and at what point in their musical and cognitive development can vary drastically. The purpose of this research is to understand how two groups of musicians, undergraduate vocal performance majors and undergraduate piano performance majors, developed (or consequently failed to develop) their respective knowledge pertaining to effective practice prior to entering the university setting, and how their practice habits changed (or consequently failed to change) after beginning study with a university instructor. This is accomplished by comparing the practice habits of the two groups prior to entering the university setting, and, after gaining admission into the degree program. Findings are supplemented with recent research pertaining to the study of learning and various types of practice.
An Exploration of Elementary L2 Learners' Use of Metacognitive Strategies
Authors:   , McNeel Michele E.
Published: February 2025

This multiple case study examined the experiences of elementary L2 learners who received instruction in either reciprocal teaching or the think aloud strategy (TAS), and identified patterns of use that emerged from participants' employment of the strategies. The three L2 participants took a pre- test and a posttest, were recorded using the strategies, and responded to interview questions about the strategies. Using qualitative data analysis techniques, four themes emerged from analysis of the data, including; talking like a teacher, I know what I know, established strategies, and declines to use the steps in the strategy. Implications from these findings suggest that the discussion facilitated by reciprocal teaching assists elementary L2 participants in better understanding the text and also supports their language acquisition, whereas TAS does not facilitate discussion. Further, even though reciprocal teaching promotes discussion, teacher assistance during discussion is necessary. Finally, it is essential that teachers are mindful of students' understandings of topics and the difficulty of texts used when students are learning the strategies.
A Comparison of Fixed- and Variable-Ratio Token Exchange-Production Schedules with Children with Autism Spectrum Disorder
Authors:   , McNeely Mitchell P
Published: February 2025

The token economy is a widely used and versatile motivational system within applied behavior analysis. Moreover, token reinforcement procedures have been shown to be highly effective in the treatment of children with autism spectrum disorder (ASD). In the experimental analysis of behavior, token reinforcement contingencies are conceptualized as three interconnected schedule components: (1) the token-production schedule, (2) the exchange-production schedule, and (3) the token-exchange schedule. Basic work with nonhuman subjects has demonstrated that the exchange-production schedule is the primary driver of performance in these arrangements, and that variable-ratio exchange-production results in reduced pre-ratio pausing and greater overall rates of responding relative to fixed-ratio exchange-production schedules. However, little applied research has been conducted to assess the generality of these findings within applied settings. The purpose of this study was to determine if fixed- and variable-ratio token exchange-production schedules would exert differential effects on pre-ratio pausing and overall rates of responding for three children with ASD during a free-operant sorting task. The results showed that pre-ratio pausing and overall rates of responding were not differentially effected by the fixed- and variable-ratio exchange-production schedules. Discrepancies between the experimental work and the current study are discussed along with additional limitations.
Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley, 1848-1870
Authors:   , Ballesteros Nicholas A.
Published: February 2025

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley is an examination of the relationships created during the mid-nineteenth century between Anglo and Tejano elites in the five counties that make up the Lower Rio Grande Valley. Conducted through a quantitative lens, the five-chapter study seeks to demonstrate that, although the period between 1848 and 1870 was fraught with conflict and violence, the Anglo and Tejano elite of the Lower Rio Grande Valley came together in cooperation in order not only to survive these troubling times but to prosper. The thesis begins by identifying and analyzing the economic and political elite in the Lower Rio Grande Valley during the 1850s. A new crop of Anglo immigrants arrived with the Mexican-American War, but only a small number willing to assimilate to local Tejano culture were able to leave their mark on the Lower Valley. Chapter 4 relates the effect of the Civil War on the elite of the Lower Valley. It explores the profitable cotton trade during the war and the struggle that both Anglo and Tejano elites faced during Reconstruction. The thesis concludes with a macro-analysis of the twenty-two-year period from 1848-1870. It summarizes overall trends found in both the Anglo and Tejano elite communities and challenges the often-repeated argument of rapid dispossession by Anglos.
Contingency Management of Physical Rehabilitation: The Role of Feedback
Authors:   , Armshaw Brennan P
Published: February 2025

Modern advances in technology have allowed for an increase in the precision with which we are able to measure, record, and affect behavior. These developments suggest that the domains in which behavior analysis might contribute are considerably broader than previously appreciated, for instance the area of behavioral medicine. One way the field of behavior analysis can begin to address problems in behavioral medicine is with biosensor technology, like surface electromyography (sEMG). For sEMG technology to be useful in behavioral medicine, specifically recovery from total knee arthroplasty, a reference value (the maximum voluntary individual contraction-MVIC) must be established. The MVIC value allows for the comparison of data across days and may allow the programming of contingencies. However, current MVIC methods fall short. Study 1 compares MVIC values produced by a participant given the typical instruction only method with two alternative methods: instruction + feedback, and instruction + feedback in a game context. Across 10 participants both feedback conditions lead to higher MVIC values then the instruction only condition. Study 2 applies the MVIC techniques developed during Study 1 to an exercise procedure. Using an MVIC value as the criteria for feedback Study 2 compares the same three conditions, however this time assessing for the conditions under which exercise performance is optimal. Across all 9 participants the instruction + feedback in a game context lead to the participant ‘working harder' and 8 out of 9 participants exceeded the MVIC value more often during this condition then in the other two conditions.
Wrestling with the Past: How National Wrestling Lost Its Regional Heritage
Authors:   , Treadway William T.
Published: February 2025

Through a combination of stringent and deceptive corporate control of sources, as well as an academic blind spot on certain low-brow subcultures, there has been a lack of serious study of the various regional professional wrestling traditions that crossed the United States until the end of the 1980s. An in-depth examination of a wide range of books, newsletters, and interviews shows a rich history with a deep economic, social, and creative diversity that has been largely ignored as the industry has moved towards monopolization under Vincent Kennedy McMahon. The various regions are divided into three groups: those that closed on their own, those that fell in competition with McMahon, and those that survived into the era of national corporate pro wrestling. This organization challenges the narrative that regional pro wrestling came to an end solely due to the business power of McMahon. The first group looks at Northern California, Southern California, Georgia, and North Texas. The second group examines the independent wrestling companies Mid-South Wrestling and the American Wrestling Association, and their attempts to compete with McMahon on a national level. The group also explores how the intense local fan bases in Portland and Memphis buoyed the local pro wrestling promotions for a time from outside competition from McMahon. The third group contains Jim Crockett Productions and the World Wide Wrestling Federation. These two organizations eventually became the two major corporate wrestling entities World Championship Wrestling and the World Wrestling Federation, respectively. A glossary of terms is included.
Untrammeled by Man? An Ethnographic Approach of Outdoor Recreation Management in Charon's Garden Wilderness
Authors:   , Lukins Gabrielle M
Published: February 2025

Charon's Garden Wilderness Area within the Wichita Mountains National Wildlife Refuge in Oklahoma is a landscape that is granted federal protection through the Wilderness Act of 1964. The discourse of wilderness management is influenced by governmental policies and practice which organize knowledge surrounding the natural landscape, like with the formation and semantics of the Wilderness Act. The Wilderness Act establishes characteristics that are designed to monitor and control the landscape and serve as a baseline and criterion for further wilderness preservation. These characteristics render the wilderness space as governable. Conservation management alternatives are identified which bypass the duality of nature from western society suggested by the discourse of environmental policy. These alternatives are understood under two notions of behaviors and perceptions. The project's goal is to uncover wilderness users' recreation behaviors and perceptions of wilderness as a designated space. Through understanding and assessing user's behaviors and perception of wilderness, alternative policies and practices that offer sustainable management practices and recreation opportunities can be developed.
Discovering Solutions: How are Journalists Applying Solutions Journalism to Change the Way News is Reported and What Do They Hope to Accomplish?
Authors:   , Porter Ashley Elizabeth
Published: February 2025

Solutions journalism, rigorous reporting on responses to social problems, has gained great traction in the last decade. Using positive psychology theory, also known as the theory of well-being, this qualitative study examines the impact of reporting while using solutions journalism techniques. Applying the five pillars of positive psychology theory: positive emotion, engagement, positive relationships, meaning and accomplishment (PERMA), this study used interviews and content analysis to investigate how journalists are applying the tools of solutions journalism as well as what they hope to accomplish in the process. Findings revealed that the application of solutions journalism techniques produces hope and community engagement resulting in flourishing and positive change for individuals, communities and all involved in the reporting process.
Establishing Criterion on a Personality-Based Assessment for Employment: A Latent Class Analysis of Faking Behavior
Authors:   , Johnson Casey W.
Published: February 2025

Personality assessments have a long history in psychology and have become the backbone of the human capital management industry, with the Big-Five model being the most prevalent. The central criticism of personality assessments for employment decisions is validity of responses since applicants for employment often endorse items to make themselves more desirable for hire, referred to as faking behavior. The present study examined faking behavior using the Assess Personality Survey (APS). Using a sample of applicant and incumbent data (N = 8,020), the objective was to identify response difference between applicant and incumbents, and the prevalence of faking behavior in applicants. Latent class analysis (LCA) was used to compare groups. Results indicate a clear distinction between applicant and incumbent response patterns. Additional analyses suggest 6 classes of testing patterns among applicants, and results are compared with previous faking identification procedures to improve criteria used to establish faking behavior in respondents.
La ley de memoria histórica en el cine y la novela españoles
Authors:   , Kennedy Tara L
Published: February 2025

This thesis investigates the Spanish identity crisis through structural, political and representational intersectionality by means of the Law of Historic Memory, also known as LEY 52/2007 del 26 de diciembre. This work, written in Spanish, explores relational aspects of various contemporary themes within four post-Franco novels and four Spanish films: Réquiem por un campesino español by Ramón J. Sender and its corresponding film directed by Francesc Betriu; Soldados de Salamina by Javier Cercas and its corresponding film directed by David Trueba; La voz dormida by Dulce Chacón and its corresponding film directed by Benito Zambrano; and Los girasoles ciegos by Alberto Méndez and its corresponding film directed by José Luis Cuerda. Linked by a variety of human elements that affect the individual as much as the collective, the works explore sacrifice, betrayal, indifference and injustice. Each novel and movie pair offers a glimpse of individual memory that, at the same time, belongs to collective memory. Delving into the effects of LEY, this thesis considers the role of the Catholic Church, the general atrocities of war, the role of women in the Spanish Civil War, and the fractured family unit. Lastly, this thesis delineates how these effects apply to the healing of individual and collective memories so as to recover what it means to be Spanish.
Anthropology of Aging: Assessment of Old Age Needs and Ethical Issues regarding the Use of Assistive Technologies
Authors:   , Atibaka Sunday O
Published: February 2025

The main goal of this research has been to investigate elderly people's needs, perceptions, fears, hopes, and expectation regarding elderly care, including ethical issues linked to assistive technologies. As faith seems to take an important place in how some elders face the aging process, the spiritual dimension was also included. Therefore, the research was conducted among 15 church congregants. Results show that most respondents fear the physical and mental decay due to aging, often resulting in becoming a burden to someone else, along with abandonment and lack of financial resources. Most ethnic groups perceive that other cultures take better care of their elders than their own. Faith seems to offer a great support, as it gives the confidence that divine power will always be there for them even beyond death. The respondents in this research suggest that guidance should be provided in a more structured way, more focus should go on the youth and the elderly, more activities should be organized and practical information should be shared. Regarding the ethical issues of assistive technologies, they are not well informed about their possibilities but acknowledge their potential usefulness, combined with human care. They don't want technology to be too intrusive in their daily life, but they are willing to sacrifice (part of) their privacy for more (medical) safety. There is a general concern that the access to qualitative care would be depending on financial resources.
Contribution of Psychopathic Traits in the Prediction of Generalized Prejudice in Males
Authors:   , Mark Daniel
Published: February 2025

Very few studies have investigated how psychopathic traits might contribute to our understanding of prejudicial attitudes. Moreover, previous studies involve a number of limitations which cloud interpretation of their findings. The current study examined the relationship between prejudice and a number of its predictors (e.g., social dominance orientation (SDO) and right-wing authoritarianism (RWA)), while also including psychopathic traits and an innovative new measure of empathy using an online sample. A path analytic framework was employed to comprehensively model relations among psychopathic traits, SDO, RWA, and affective empathy domains in the prediction of generalized prejudice. Overall, there was support for certain psychopathic traits being modest predictors of racial prejudice, although more proximal measures were much stronger predictors. The results revealed a number of novel relationships that may help in further understanding the links between psychopathic propensities, empathy, and social-cognitive variables predictive of racial prejudice.
Development of a Wireless Sensor Network System for Occupancy Monitoring
Authors:   , Onoriose Ovie
Published: February 2025

The ways that people use libraries have changed drastically over the past few decades. Proliferation of computers and the internet have led to the purpose of libraries expanding from being only places where information is stored, to spaces where people teach, learn, create, and collaborate. Due to this, the ways that people occupy the space in a library have also changed. To keep up with these changes and improve patron experience, institutions collect data to determine how their spaces are being used. This thesis involves the development a system that collects, stores, and analyzes data relevant to occupancy to learn how a space is being utilized. Data is collected from a temperature and humidity sensor, passive Infrared sensor, and an Infrared thermal sensor array to observe people as they occupy and move through a space. Algorithms were developed to analyze the collected sensor data to determine how many people are occupying a space or the directions that people are moving through a space. The algorithms demonstrate the ability to track multiple people moving through a space as well as count the number of people in a space with an RMSE of roughly 0.39 people.
Detection of Generalizable Clone Security Coding Bugs Using Graphs and Learning Algorithms
Authors:   , Mayo Quentin R
Published: February 2025

This research methodology isolates coding properties and identifies the probability of security vulnerabilities using machine learning and historical data. Several approaches characterize the effectiveness of detecting security-related bugs that manifest as vulnerabilities, but none utilize vulnerability patch information. The main contribution of this research is a framework to analyze LLVM Intermediate Representation Code and merging core source code representations using source code properties. This research is beneficial because it allows source programs to be transformed into a graphical form and users can extract specific code properties related to vulnerable functions. The result is an improved approach to detect, identify, and track software system vulnerabilities based on a performance evaluation. The methodology uses historical function level vulnerability information, unique feature extraction techniques, a novel code property graph, and learning algorithms to minimize the amount of end user domain knowledge necessary to detect vulnerabilities in applications. The analysis shows approximately 99% precision and recall to detect known vulnerabilities in the National Institute of Standards and Technology (NIST) Software Assurance Metrics and Tool Evaluation (SAMATE) project. Furthermore, 72% percent of the historical vulnerabilities in the OpenSSL testing environment were detected using a linear support vector classifier (SVC) model.
Quantum Coherence Effects Coupled via Plasmons
Authors:   , Moazzezi Mojtaba
Published: February 2025

This thesis is an attempt at studying quantum coherence effects coupled via plasmons. After introducing the quantum coherence in atomic systems in Chapter 1, we utilize it in Chapter 2 to demonstrate a new technique of detection of motion of single atoms or irons inside an optical cavity. By taking into account the interaction of coherences with surface plasmonic waves excited in metal nanoparticles, we provide a theoretical model along with experimental data in Chapter 3 to describe the modification of Raman spectra near metal nanoparticles. We show in chapter 4 that starting from two emitters, coupled via a plasmonic field, the symmetry breaking occurs, making detectable the simultaneous existence of the fast super-radiance and the slow sub-radiance emission of dye fluorescence near a plasmonic surface. In Chapter 5, we study the photon statistics of a group of emitters coupled via plasmons and by the use of quantum regression theorem, we provide a theoretical model to fully investigate the dependence of photon bunching and anti-bunching effects to the interaction between atoms, fields and surrounding mediums.
Reclaiming Female Virtue: Social Hygiene, Venereal Disease and Texas Reclamation Centers during World War I
Authors:   , Bridges Jennifer
Published: February 2025

During the Progressive Era in the United States, social hygiene reformers underwent a fundamental change in their stance toward women accused of prostitution or promiscuous behavior. Rather than viewing such women as unfortunate victims of circumstance who were worthy of compassion, many Progressives deemed them as predatory villains who instead deserved incarceration, forced rehabilitation, and non-consenting medical interference. Texas, due to the many military bases within its borders, became a key battleground in this moral crusade against women as the carriers and proliferators of VD. "Promiscuous" women were seen as not only dangerous to the soldiers but also as a threat to the nation's security, creating an environment that led Texas Progressives to suppress women's civil liberties in the name of protecting soldiers. The catalyst for this change in attitude was World War I. The Great War brought to the forefront an unpleasant reality facing a significant percentage of America's fighting men: venereal disease. While combating sexually transmitted diseases was a serious medical and manpower concern for the military in the era before penicillin, the sole focus on women as the carriers and proliferators of VD led to a nationwide campaign against the "social evil" that demonized women and led to the suspension of thousands of women's habeas corpus rights. This dissertation examines how the twin crusades of Progressivism and the War to End All Wars created conditions in Texas that for many women meant appalling repression rather than progress toward the enjoyment of greater equality.
Fabrication and Study of the Optical Properties of 3D Photonic Crystals and 2D Graded Photonic Super-Crystals
Authors:   , Lowell David
Published: February 2025

In this dissertation, I am presenting my research on the fabrication and simulation of the optical properties of 3D photonic crystals and 2D graded photonic super-crystals. The 3D photonic crystals were fabricated using holographic lithography with a single, custom-built reflective optical element (ROE) and single exposure from a visible light laser. Fully 3D photonic crystals with 4-fold, 5- fold, and 6-fold symmetries were fabricated using the flexible, 3D printed ROE. In addition, novel 2D graded photonic super-crystals were fabricated using a spatial light modulator (SLM) in a 4f setup for pixel-by-pixel phase engineering. The SLM was used to control the phase and intensity of sets of beams to fabricate the 2D photonic crystals in a single exposure. The 2D photonic crystals integrate super-cell periodicities with 4-fold, 5-fold, and 6-fold symmetries and a graded fill fraction. The simulations of the 2D graded photonic super-crystals show extraordinary properties such as full photonic band gaps and cavity modes with Q-factors of ~106. This research could help in the development of organic light emitting diodes, high-efficiency solar cells, and other devices.
Exploring the Conceptualization, Operationalization, and Application of Relational Mindfulness
Authors:   , Sigdyal Pratigya
Published: February 2025

Individuals vary in the level of their mental presence during interactions; some individuals are mentally present with others, while others are mired in their thoughts and emotions. Scholarly work on this area is limited, and we know very little about why some individuals display mental presence better than others. In this dissertation, I explore the concept through a series of three essays. In the first essay, I define relational mindfulness as the ability to be mentally present with others. Further, I propose that relational mindfulness has three essential features: others' focus, thought-switching, and emotional acceptance. I operationalize the scale to measure relational mindfulness and investigate its nomological network by correlating it with different constructs. Data from four different samples provide support for the three-factor structure of relational mindfulness and provide support for the relationship of relational mindfulness with related constructs. In the second essay, I explore the relevance of relational mindfulness for front-line employees by investigating the two pathways through which relational mindfulness can reduce fatigue of front-line employees. In the first pathway, I posited that relational mindfulness would decrease the intensity of surface acting of employees when their customers mistreat them, and thus reduce fatigue of employees. In the second pathway, I posited that relational mindfulness would increase the frequency of positive interactions between employees and customers, and thereby decrease fatigue experienced by employees. I tested the model by conducting two different studies. Overall, the results provided support for the posited hypotheses. In the third essay, I tested whether relational mindfulness can be enhanced through a mindfulness meditation by conducting a quasi-experimental study. Two groups; experimental and comparison groups participated in the pre-test, post-test surveys, and weekly surveys during the experiment. The results suggested that participants in both groups increased their relational mindfulness over time and there was no evidence that individuals in the mindfulness group differed from the comparison group.
Distributed Consensus, Optimization and Computation in Networked Systems
Authors:   , Yao Lisha
Published: February 2025

In the first part of this thesis, we propose a distributed consensus algorithm under multi-layer multi-group structure with communication time delays. It is proven that the consensus will be achieved in both time-varying and fixed communication delays. In the second part, we study the distributed optimization problem with a finite-time mechanism. It is shown that our distributed proportional-integral algorithm can exponentially converge to the unique global minimizer when the gain parameters satisfy the sufficient conditions. Moreover, we equip the proposed algorithm with a decentralized algorithm, which enables an arbitrarily chosen agent to compute the exact global minimizer within a finite number of time steps, using its own states observed over a successive time steps. In the third part, it is shown the implementation of accelerated distributed energy management for microgrids is achieved. The results presented in the thesis are corroborated by simulations or experiments.

Authors:   , McCloud Margie J
Published: February 2025

The purpose of the study was to examine the effects of charter schools on African-American students, this study sought to determine if the practice of connectedness, alignment, rigor, and engagement (C.A.R.E.) influenced academic outcomes. The research methodology employed a meta-analysis in conjunction with a systematic review as a cross-reference and to address variables not covered in the meta-analysis. Utilizing a meta-analysis allowed for a synthesis of the existing quantitative published data to consolidate the results. This produced a specific report of achievement data for African-American students. The results revealed that regardless of region, subject, type of assessment, or school focus charter school do positively influence African-American students' academic outcomes. This study also found the practices connectedness, alignment, rigor, and engagement, the C.A.R.E. model when employed in schools improve academic outcomes, especially when combined and implemented with best practices.

Allowing Students to Have VOICES (Voluntary Options in Chemical Education Schedules) in General Chemistry I
Authors:   , Ford Robyn Lynn
Published: February 2025

The purpose of this investigation (a quasi-experimental design called a non-equivalent design group (NEDG)) was to determine if allowing students in a science majors general Chemistry I course the choice in establishing the due dates that their homework was due to the instructor would improve course averages. This study covered two semesters with a total of 288 students participating with n = 158 in the fall and n = 130 in the spring. The students self-selected the homework group, VOICES, that best fit his/her needs which included (1) the instructor's homework schedule, (2) a student-customized schedule or a schedule that followed the exam schedule, or (3) all homework due by the last class day prior to the final exam. Online homework was assigned and graded with individual assignment and homework average grades collected and analyzed. No statistically significant differences were found among the VOICES groups with respect to final course average. Other results of this study replicated findings in the literature; namely, that there is a higher correlation between mathematics skills and course success. Course averages of students who had completed Calculus I or higher were statistically significantly higher than students with less completed mathematics coursework in all VOICES groups. Also, the percentage of successful students in the on-sequence semester (fall) was higher than the percentage of students in the off-sequence semester (spring). No differences were seen in any VOICES group's student demographics or high school chemistry preparation.
Smart Microgrid Energy Management Using a Wireless Sensor Network

Modern power generation aims to utilize renewable energy sources such as solar power and wind to supply customers with power. This approach avoids exhaustion of fossil fuels as well as provides clean energy. Microgrids have become popular over the years, as they contain multiple renewable power sources and battery storage systems to supply power to the entities within the network. These microgrids can share power with the main grid or operate islanded from the grid. During an islanded scenario, self-sustainability is crucial to ensure balance between supply and demand within the microgrid. This can be accomplished by a smart microgrid that can monitor system conditions and respond to power imbalance by shedding loads based on priority. Such a method ensures security of the most important loads in the system and manages energy by automatically disconnecting lower priority loads until system conditions have improved. This thesis introduces a prioritized load shedding algorithm for the microgrid at the University of North Texas Discovery Park and highlight how such an energy management algorithm can add reliability to an islanded microgrid.
Where are the Women in the Ebola Crisis? An Analysis of Gendered Reporting and the Information Behavior Patterns of Journalists Covering a Health Outbreak

Published: February 2025

Health officials estimate that the 2014 Ebola crisis disproportionately victimized women, who made up 75% of the disease's victims. This interdisciplinary study has two main goals. The first is to evaluate the news media's performance in relation to their representation of women caught up in the Ebola crisis because the media play an important role in influencing public responses to health. This study sought to understand the information behavior patterns of journalists who covered the Ebola crisis by analyzing how job tasks influence a journalist's information behavior. This study employed qualitative methods to study the perceptions of journalists who covered the 2014 Ebola outbreak. Semi-structured interviews were conducted with Liberian and American journalists who covered the outbreak to understand the choices that guided their reporting of the Ebola crisis. A content analysis of The New York Times, The Times, and The Inquirer was also conducted to examine the new media's representation of women in an outbreak which mostly victimized women. The findings suggest that covering a dangerous assignment like Ebola affected the information behavior patterns of journalists. Audience needs, the timing of coverage, fear, and the accessibility of sources, were some of the factors that influenced the news gathering decisions taken by the reporters. The findings also suggest that women were mostly underrepresented by the media as sources, experts and subjects.
Electrically Tunable Absorption and Perfect Absorption Using Aluminum-Doped Zinc Oxide and Graphene Sandwiched in Oxides

Understanding the fundamental physics in light absorption and perfect light absorption is vital for device applications in detector, sensor, solar energy harvesting and imaging. In this research study, a large area fabrication of Al-doped ZnO/Al2O3/graphene/Al2O3/gold/silicon device was enabled by a spin-processable hydrophilic mono-layer graphene oxide. In contrast to the optical properties of noble metals, which cannot be tuned or changed, the permittivity of transparent metal oxides, such as Al-doped ZnO and indium tin oxide, are tunable. Their optical properties can be adjusted via doping or tuned electrically through carrier accumulation and depletion, providing great advantages for designing tunable photonic devices or realizing perfect absorption. A significant shift of Raman frequency up to 360 cm-1 was observed from graphene in the fabricated device reported in this work. The absorption from the device was tunable with a negative voltage applied on the Al-doped ZnO side. The generated absorption change was sustainable when the voltage was off and erasable when a positive voltage was applied. The reflection change was explained by the Fermi level change in graphene. The sustainability of tuned optical property in graphene can lead to a design of device with less power consumption.

The purpose of this research was to investigate the relationships between job satisfaction, work engagement, and turnover intention of health science teachers in the state of Texas. The healthcare profession is one of the largest growing occupations in the U.S. nationwide. The job growth outlook for healthcare professionals is projected to be on average 34% between 2014 and 2024. Despite the growing healthcare job categories, there is a shortage of healthcare professionals in the U.S. This study addressed the shortage of health science teachers in secondary education. Considering the importance of healthcare, especially with an aging U.S. population, it is critical to study the impact of work engagement and job satisfaction on teacher intent to leave the health science teaching profession. Through a correlational survey research design it was found that job satisfaction and work engagement are negatively related to turnover intention. Hierarchical regression analysis indicated that job satisfaction accounted for 39.6% of the variation in turnover intention. Findings also showed that work engagement did not moderate the relationship between job satisfaction and turnover intention. Implications for research and practice are discussed and conclusions are provided.
