The Impact of Commuting on Mental Health
Authors:   , Malek-Ahmadi John
Published: February 2025

The purpose of this research is to explicate the relationship between commuting behavior, stress, and mental health. The overall results from the regression analysis turned out to be inconclusive given the researcher's initial hypothesis. The commute time reported by respondents did not have a statistically significant bearing on mental health outcomes. This was true for both the normal sample, and the sample that was split by gender.
MBE Growth and Characterization of Graphene on Well-Defined Cobalt Oxide Surfaces: Graphene Spintronics without Spin Injection
Authors:   , Olanipekun Opeyemi B.
Published: February 2025

The direct growth of graphene by scalable methods on magnetic insulators is important for industrial development of graphene-based spintronic devices, and a route towards substrate-induced spin polarization in graphene without spin injection. X-ray photoelectron spectroscopy (XPS), low energy electron diffraction LEED, electron energy loss spectroscopy (EELS) and Auger electron spectroscopy (AES) demonstrate the growth of Co3O4(111) and CoO(111) to thicknesses greater than 100 Å on Ru(0001) surfaces, by molecular beam epitaxy (MBE). The results obtained show that the formation of the different cobalt oxide phases is O2 partial pressure dependent under same temperature and vacuum conditions and that the films are stoichiometric. Electrical I-V measurement of the Co3O4(111) show characteristic hysteresis indicative of resistive switching and thus suitable for advanced device applications. In addition, the growth of Co0.5Fe0.5O(111) was also achieved by MBE and these films were observed to be OH-stabilized. C MBE yielded azimuthally oriented few layer graphene on the OH-terminated CoO(111), Co0.5Fe0.5O(111) and Co3O4(111). AES confirms the growth of (111)-ordered sp2 C layers. EELS data demonstrate significant graphene-to-oxide charge transfer with Raman spectroscopy showing the formation of a graphene-oxide buffer layer, in excellent agreement with previous theoretical predictions. XPS data show the formation of C-O covalent bonding between the oxide layer and the first monolayer (ML) of C. LEED data reveal that the graphene overlayers on all substrates exhibit C3V. The reduction of graphene symmetry to C3V – correlated with C-O bond formation – enables spin-orbit coupling in graphene. Consequences may include a significant band gap and room temperature spin Hall effect – important for spintronic device applications. The results suggest a general pattern of graphene/graphene oxide growth and symmetry lowering for graphene formation on the (111) surfaces of rocksalt-structured oxides.
Assessment of Competencies among Doctoral Trainees in Psychology
Authors:   , Price Samantha
Published: February 2025

The recent shift to a culture of competence has permeated several areas of professional psychology, including competency identification, competency-based education training, and competency assessment. A competency framework has also been applied to various programs and specialty areas within psychology, such as clinical, counseling, clinical health, school, cultural diversity, neuro-, gero-, child, and pediatric psychology. Despite the spread of competency focus throughout psychology, few standardized measures of competency assessment have been developed. To the authors' knowledge, only four published studies on measures of competency assessment in psychology currently exist. While these measures demonstrate significant steps in progressing the assessment of confidence, three of these measures were designed for use with individual programs, two of these international (i.e., UK and Taiwan). The current study applied the seminal Competency Benchmarks, via a recently adapted benchmarks form (i.e., Practicum Evaluation form; PEF), to practicum students at the University of North Texas. In addition to traditional supervisor ratings, the present study also involved self-, peer supervisor, and peer supervisee ratings to provide 360-degree evaluations. Item-response theory (IRT) was used to evaluate the psychometric properties of the PEF and inform potential revisions of this form. Supervisor ratings of competency were found to fit the Rasch model specified, lending support to use of the benchmarks framework as assessed by this form. Self- and peer-ratings were significantly correlated with supervisor ratings, indicating that there may be some utility to 360-degree evaluations. Finally, as predicted, foundational competencies were rated as significantly higher than functional competencies, and competencies improved significantly with training. Results of the current study provide clarity about the utility of the PEF and inform our understanding of practicum-level competencies.
Development of a Natural Fiber Mat Plywood Composite
Authors:   , Anthireddy Prasanna Kumar
Published: February 2025

Natural fibers like kenaf, hemp, flax and sisal fiber are becoming alternatives to conventional petroleum fibers for many applications. One such applications is the use of Non-woven bio-fiber mats in the automobile and construction industries. Non-woven hemp fiber mats were used to manufacture plywood in order to optimize the plywood structure. Hemp fiber mats possess strong mechanical properties that comparable to synthetic fibers which include tensile strength and tensile modulus. This study focuses on the use of hemp fiber mat as a core layer in plywood sandwich composite. The optimization of fiber mat plywood was done by performing a three factor experiment. The three factors selected for this experiment were number of hemp mat layers in the core, mat treatment of the hemp mat, and the glue content in the core. From the analysis of all treatments it was determined that single hemp mat had the highest effect on improving the properties of the plywood structure.
Community of Inquiry Meets Critical Discourse Analysis (CDA): A CDA of Asynchronous Computer-Conference Discourse with Seminary Students in India
Authors:   , George Stephen
Published: February 2025

The purpose of this study was to better understand student learning in asynchronous computer-conference discourse (ASD) for non-native speakers of English in India through the Community of Inquiry (COI) framework. The study looked at ASD from an online course taught in the fall of 2015 to 25 students in a seminary in South India. All but one of the students were non-native speakers of English. The class consisted of 22 men and 3 women. Eight students spoke languages from the Dravidian family of languages (Malayalam, Tamil, Telegu and Kannada). Eight students were from the Northeastern states of Manipur, Nagaland and Tripura, where most languages are from the Sino-Tibetan family. Three students were native speakers of Indo-Aryan languages (Odiya and Assamese). Five students were from Myanmar representing several Sino-Tibetan languages. The COI is a framework used to understand learning in ASD, often used in online learning. To study the ASD of this group, critical discourse analysis (CDA) was used with the COI to capture the unique socio-cultural and linguistic conditions of this group. The study revealed that non-native speakers of English often reach the Exploration phase of learning but rarely show evidence of reaching the Resolution phase. This phenomenon was also observed in native English speakers as reported in the literature. Also, the structure of ASD showed that students took an examination approach to discussion shaped in part by their epistemology. This examination approach shaped how knowledge was constructed. CDA also showed that the discourse acquired an instructor-centered structure in which Resolution and Repair were initiated and finalized by the instructor. The study advances the COI framework by undergirding it with a theory of asynchronous discourse using critical discourse analysis and capturing cognitive, social and teaching presence phenomena for non-native speakers that were not observed through the traditional COI framework. These phenomena were driven by cultural, epistemological, and linguistic forces and require a rethinking of the COI for contexts outside of North America. The study also demonstrates that learning for non-native speakers in ASD is challenged by these very same forces. Therefore, design for online learning should account for these phenomena.
The King Arrives: Chinese Government Inspections and Their Effects
Authors:   , Xi Jinrui
Published: February 2025

This dissertation studies a critical facet of Chinese politics, inspections by higher Chinese government to villages. Principally, it looks at how village economic development determines government inspection decisions and how inspections, once conducted, impact village politics. Specifically, I argue that villages perceived as destabilizing to the Chinese regime, villages with higher levels of economic inequality and villages located at the two extremes of economic development, should see more inspections. In addition, I argue that inspections, in return, drive village politics: they increase village leaders' governing efficacy and raise villagers' political awareness. This theory has received strong support from both field work and quantitative empirical tests using the Chinese Household Income Project (2002) dataset.
Mobile-Based Smart Auscultation
Authors:   , Chitnis Anurag
Published: February 2025

In developing countries, acute respiratory infections (ARIs) are responsible for two million deaths per year. Most victims are children who are less than 5 years old. Pneumonia kills 5000 children per day. The statistics for cardiovascular diseases (CVDs) are even more alarming. According to a 2009 report from the World Health Organization (WHO), CVDs kill 17 million people per year. In many resource-poor parts of the world such as India and China, many people are unable to access cardiologists, pulmonologists, and other specialists. Hence, low skilled health professionals are responsible for screening people for ARIs and CVDs in these areas. For example, in the rural areas of the Philippines, there is only one doctor for every 10,000 people. By contrast, the United States has one doctor for every 500 Americans. Due to advances in technology, it is now possible to use a smartphone for audio recording, signal processing, and machine learning. In my thesis, I have developed an Android application named Smart Auscultation. Auscultation is a process in which physicians listen to heart and lung sounds to diagnose disorders. Cardiologists spend years mastering this skill. The Smart Auscultation application is capable of recording and classifying heart sounds, and can be used by public or clinical health workers. This application can detect abnormal heart sounds with up to 92-98% accuracy. In addition, the application can record, but not yet classify, lung sounds. This application will be able to help save thousands of lives by allowing anyone to identify abnormal heart and lung sounds.
A Woman's Place is at Work: The Rise of Women's Paid Labor in Five Texas Cities, 1900-1940
Authors:   , Scott Codee
Published: February 2025

This thesis is a quantitative analysis of women working for pay aged sixteen and older in five mid-size Texas cities from 1900 to 1940. It examines wage-earning women primarily in terms of race, age, marital status, and occupation at each census year and how those key factors changed over time. This study investigates what, if any, trends occurred in the types of occupations open to women and the roles of race, age, and marital status in women working for pay in the first forty years of the 20th century.
A Systemic Model for Family Functioning: Mutual Influences of Spousal Attachment, Marital Adjustment, and Coparenting
Authors:   , Young Anne Michelle
Published: February 2025

The current study examined direct and indirect influences of romantic attachment processes, marital adjustment, and the coparenting relationship on family functioning. Data was collected from a community sample of 86 heterosexual couples with a child aged eight to eleven living in the home. Both spouses completed a demographic questionnaire, the Experiences in Close Relationships Scale, the Dyadic Adjustment Scale, the Coparenting Scale, and the Self-Report Family Inventory as part of a larger study on family processes in middle childhood. Data analysis included multilevel modeling, utilizing the actor-partner interdependence model. Results indicated that marital adjustment mediated the association between attachment processes and family functioning, suggesting that a healthy marital relationship is an important variable that helps explain links between attachment security and the family functioning. Findings also highlighted the benefit of conceptualizing adult romantic attachment, marital, and coparental subsystems within a systemic framework.
Mobile Learning in a Mobile World: Understanding the Views of Parents with Mobile Technology in the Singaporean Elementary Classroom
Authors:   , Riddle Joseph R.
Published: February 2025

Personal handheld mobile technology represents a growing topic of interest for K-12 educators. Devices such as iPads, tablets, and smartphones, in particular, are becoming more ubiquitous in society and prevalent in classrooms of children of all ages. The ease of access, combined with growing functionality and capacity of these devices creates opportunities that were previously unimaginable. Professional educators are beginning to recognize the value such devices offer for enriching and expanding opportunities for learning both inside and outside of the classroom. The views of educators and students regarding mobile technology have been well documented in existing literature. What is less clear is how parents view personal mobile technology when applied to formal and informal learning opportunities. Using quantitative analysis, this study examines the views of parents when mobile technology is utilized in Singaporean third grade classrooms. This study represents a pioneering effort to better understand the evolving role of parents and serves as a foundation for future research to explore the role of parents as partners when personal mobile technology is used for learning. The constructs identified in this study reveal that parents do believe technology skills are important in the modern age of learning and working.
Interactive Networks in Forgotten Lyres: Critical Analysis and Original Composition
Authors:   , Harenda Timothy
Published: February 2025

Forgotten Lyres is a musical response to Percy Bysshe Shelley's poem Mutability, which depicts the fragility and unpredictable nature of human life. Four independent chamber ensembles make up the performing forces of Forgotten Lyres; the musicians evoke the topics of Shelley's text as they interact and coordinate with one another according to a variety of paradigms and without the use of a conductor. This essay focuses on the approaches to coordination within and between ensembles, and the ways in which the musicians' interactions can evoke and convey Shelley's texts. The essay also examines works by Mel Powell, Toru Takemitsu, Witold Lutoslawski, and Pierre Boulez as examples and precursors for the coordination strategies employed in Forgotten Lyres.
Combining Select Blood-Based Biomarkers with Neuropsychological Assessment to Detect Mild Cognitive Impairment among Mexican Americans: A Molecular Neuropsychology Approach
Authors:   , Edwards Melissa L.
Published: February 2025

Mexican Americans face a significant health disparity related to the development of Mild Cognitive Impairment (MCI) when compared to other ethnic groups. Recent work has documented the utility of utilizing blood-based biomarkers in the detection of amnestic MCI among this population. Efforts to enhance the utility of biomarkers in detecting disease through the inclusion of select neuropsychological measures, an approach termed Molecular Neuropsychology, has shown promise. The present study sought to utilize the molecular neuropsychology approach and examine biobanked serum samples as well as neuropsychological assessments from the Health and Aging Brain among Latino Elders (HABLE) study. Random Forest analyses were conducted to determine the proteomic profile of MCI. Then separate linear regression analyses were conducted to determine the variance accounted for by the biomarkers within the select neuropsychological measures. Trail Making Test Part B was identified as having the least amount of variance and was combined with top five biomarkers within the MCI proteomic profile to create a biomarker-cognitive profile for detecting disease presence. This same method was applied to the amnestic and non-amnestic forms of MCI. The overall biomarker-cognitive profile was shown to be 90% accurate in the detection of MCI, with no significant increase when demographic variables were included into the model. Among amnestic MCI cases, the detection accuracy of the biomarker-cognitive profile was 92% and increased to 94% upon inclusion of demographic variables.
The Evolution of Learning Technologies within the UNC German Consortium 2000-2016: A Hermeneutic Phenomenlogical Analysis of German Faculty Member Experiences
Authors:   , Underwood Zackary W.
Published: February 2025

Beginning in 2000 and continuing today, the University of North Carolina (UNC) German Consortium offers online German courses to undergraduate students across sixteen of the seventeen UNC public universities. The delivery of online classes differs per faculty member and little previous research investigated the UNC German Consortium's learning technologies. This dissertation investigates the evolution of learning technologies within the UNC German Consortium over the last sixteen years among German faculty from different UNC public universities. Seven faculty and one administrator shared their experiences through interviews. The methodology for this research was hermeneutic phenomenology. Interviewees shared their experiences with learning technology and teaching in the UNC German Consortium including how learning technologies changed over time. Interviews were transcribed, coded, and analyzed to deduce themes. Themes included the importance of the North Carolina Research Education Network (NC REN) for teaching German online, an asynchronous versus synchronous debate, how professors taught in synchronous courses, the importance of learning management systems (LMS) systems, the resilient characteristics of UNC German Consortium faculty, and the need for continual learning as an instructor.

Crossing Over: Essays on Ethnic Parties, Electoral Politics, and Ethnic Social Conflict
Authors:   , Stewart Brandon
Published: February 2025

This dissertation analyzes several topics related to political life in ethnically divided societies. In chapter 2, I study the relationship between ethnic social conflict, such as protests, riots, and armed inter-ethnic violence, and bloc partisan identification. I find that protests have no effect on bloc support for political parties, riots increase bloc partisan identification, and that armed violence reduces this phenomenon. In chapter 3, I analyze the factors that influence the targeting of ethnic groups by ethnic parties in social conflict. I find some empirical evidence that conditions favorable to vote pooling across ethnic lines reduce group targeting by ethnic parties. In chapter 4, I analyze the effects of ethnic demography on ethnic party behavior. Through a qualitative analysis of party behavior in local elections in Macedonia, I find that ethnic parties change their strategies in response to changes in ethnic demography. I find that co-ethnic parties are less likely to challenge each other for power under conditions of split demography. In fact, under conditions of split demography, I find that co-ethnic parties have political incentives to unite behind a single party because intra-group competition jeopardizes the group's hold on power.
Social and Emotional Learning and Preservice Teacher Education: Assessing Preservice Teachers' Knowledge, Beliefs, and Attitudes
Authors:   , Dolzhenko Inna N.
Published: February 2025

In response to the main federal K-12 law, the Every Student Succeeds Act (ESSA) and the teacher education program standards, teacher education programs have tried to address social and emotional learning (SEL) content in their curricula. Adding information on SEL alone may not be enough to overcome the shortenings of many existing early childhood programs. The current study attempted to address these shortenings through the inclusion of specialized SEL strategies and sample activities in addition to traditional content on social-emotional learning and development. This study was organized within a quasi-experimental design framework. One hundred thirty-nine preservice teachers were divided between control and treatment groups. The treatment group was exposed to the intervention (i.e. additional/special SEL strategies and activities) in the modified Nurturing Children's Social Competence class, while the control group was in the traditional version of the same class (i.e. traditional instruction with no additional/special SEL strategies and activities). All students were surveyed using the SEL Beliefs Scale for Preservice Teachers and the SEL Knowledge and Attitudes Scales for Preservice Teachers. The surveys were conducted at the beginning and at the end of the semester. An exploratory factor analysis, MANOVA, and descriptive discriminant analysis were used to analyze the data. Findings revealed that preservice teachers in the treatment group gained greater knowledge about (a) SEL in general, (b) the development of SEL skills in young children, and (c) implementation of the SEL strategies in the classroom. In addition, preservice teachers in the treatment group developed more positive attitudes toward implementation of SEL strategies and the importance of teaching social and emotional skills to young children. Even though SEL beliefs did not predict treatment / control group differences, there were statistically significant differences in the development of SEL beliefs within each group. Preservice teachers in both groups highly believed that creating a SEL environment in the classroom and schoolwide is essential.
Knowing What is Useful: Rousseau's Education Concerning Being, Science, and Happiness
Authors:   , Gross Benjamin Isaak
Published: February 2025

Is there a relationship between science and happiness and, if so, what is it? Clearly, since the Enlightenment, science has increased life expectancy and bodily comfort. Is this happiness, or do humans long for something more? To examine these questions, I investigate the works of Jean-Jacques Rousseau. Specifically, I focus on the Discourses and the Emile, as he states in the Confessions that these works form a whole statement concerning the natural goodness of man. I agree with the literature that finds happiness, for Rousseau, is a sentiment one experiences when their faculties correspond to their desires, as this produces wholeness. In this dissertation, I find a form of modern science is necessary for humans to experience higher forms of happiness. This form of science is rooted in utility of the individual. To fully explain this finding, I begin with Rousseau's concept of being. By nature, our being experiences a low form of wholeness. I show Rousseau's investigation of being exposes a catch-22 situation for developing it to experience higher forms of wholeness. While freedom allows us to develop reason and judgment, we need reason and judgment to properly direct our freedom to perfect our individual being. I then show how three different types of tutors and educators, which include a scientific education, are directed by the single goal of maintaining wholeness in Emile's being so he can achieve the happiness of romantic love. Finally, I find that Emile's scientific education is an elaboration of the First Discourse and that his relationship with science, even from birth, plays a critical role for achieving romantic love in the future.
Predictors of Music Performance Anxiety in Adolescent Musicians
Authors:   , Edmonson Jordan
Published: February 2025

Music performance anxiety is an issue that affects musicians at all levels but can begin in early adolescence. The researcher investigated three variables and their ability to predict music performance anxiety: catastrophization, self-regulation, and goal-setting style. Catastrophization is a negative thought that amplifies perceived criticism. Self-regulation is a metacognitive skill that allows students to plan strategies and evaluate learning. Goal-setting style refers to a student's framework when establishing learning objectives – whether they are focused on mastering the subject matter, or only trying to avoid being the worst in the class. A sample of adolescent wind musicians (n = 68) were administered four self-reporting measures for the predictor variables and music performance anxiety. Catastrophization, self-regulation, and goal-setting style were all statistically significant in predictor music performance anxiety, with catastrophization alone explaining 69% of the variance in the predictor variable. Overall, the whole model was able to explain 46% of the variance in music performance anxiety.
Eggplant Emoji
Authors:   , Warncke Nicole
Published: February 2025

Eggplant Emoji is a documentary film that reveals a range of feminist perspectives on dick pics, sexting and online sexual harassment. Through intimate and hilarious interviews with women between the ages of 22 and 35, the film harnesses a collective voice that speaks back to the large and small ways patriarchy wields power in modern spaces, especially through sending unsolicited dick pics. By intertwining the testimonies of a dynamic group of female storytellers sitting amongst their close friends, the film provides candid and diverse commentary on this unique moment we are in, where the lines between private and public, online and offline are increasingly blurred. Until there are greater consequences, whether legal, social or otherwise, for men disrespecting women's choices and personal space, the domain of sexting is in a self-policing state and women are left to expend emotional labor to let men know why what they sent is unwanted or violating. Ultimately, the subjects' testimonials coalesce to provide suggestions for respectful, consensual sexting practices and fill in the gaps where sex education often neglects the importance of consent and communication altogether.
Design, Synthesis and Optoelectronic Properties of Monovalent Coinage Metal-Based Functional Materials toward Potential Lighting, Display and Energy-Harvesting Devices
Authors:   , Ghimire Mukunda Mani
Published: February 2025

Groundbreaking progress in molecule-based optoelectronic devices for lighting, display and energy-harvesting technologies demands highly efficient and easily processable functional materials with tunable properties governed by their molecular/supramolecular structure variations. To date, functional coordination compounds whose function is governed by non-covalent weak forces (e.g., metallophilic, dπ-acid/dπ-base stacking, halogen/halogen and/or d/π interactions) remain limited. This is unlike the situation for metal-free organic semiconductors, as most metal complexes incorporated in optoelectronic devices have their function determined by the properties of the monomeric molecular unit (e.g., Ir(III)-phenylpyridine complexes in organic light-emitting diodes (OLEDs) and Ru(II)-polypyridyl complexes in dye-sensitized solar cells (DSSCs)). This dissertation represents comprehensive results of both experimental and theoretical studies, descriptions of synthetic methods and possible application allied to monovalent coinage metal-based functional materials. The main emphasis is given to the design and synthesis of functional materials with preset material properties such as light-emitting materials, light-harvesting materials and conducting materials. In terms of advances in fundamental scientific phenomena, the major highlight of the work in this dissertation is the discovery of closed-shell polar-covalent metal-metal bonds manifested by ligand-unassisted d10-d10 covalent bonds between Cu(I) and Au(I) coinage metals in the ground electronic state (~2.87 Å; ~45 kcal/mol). Moreover, this dissertation also reports pairwise intermolecular aurophilic interactions of 3.066 Å for an Au(I) complex, representing the shortest ever reported pairwise intermolecular aurophilic distances among all coinage metal(I) cyclic trimetallic complexes to date; crystals of this complex also exhibit gigantic luminescence thermochromism of 10,200 cm-1 (violet to red). From applications prospective, the work herein presents monovalent coinage metal-based functional optoelectronic materials such as heterobimetallic complexes with near-unity photoluminescence quantum yield, metallic or semiconducting integrated donor-acceptor stacks and a new class of Au(III)-based black absorbers with cooperative intermolecular iodophilic (I…I) interactions that sensitize the harvesting of all UV, all visible, and a broad spectrum of near-IR regions of the solar spectrum. These novel functional materials of cyclic trimetallic coinage metal complexes have been characterized by a broad suit of spectroscopic and structural analysis methods in the solid state and solution.
Territorial Issue Salience: Escalation, Resources, and Ethnicity
Authors:   , Macaulay Christopher
Published: February 2025

Conflict over territory is a major concern to scholars and policymakers, and much of conflict over territory is driven by the issues that make territory more or less attractive, or salient, to states. I examine the impact that tangible and intangible issue salience has on territorial claims, and in particular, how it drives both conflict and conflict escalation. I argue that intangible issues, such as ethnic or religious kin, plays a greater role in driving more severe forms of armed conflict and conflict escalation, compared to tangible factors such as natural resources. This is theorized to be due to the difficulty in dividing territory with intangible elements, as well as domestic political pressure driving leaders to escalate. These suppositions are supported, with the finding that identity plays a particularly crucial and unique role in driving states to more severe forms of armed conflict. Further, I examine how natural resources may be viewed by states by their type and form of utilization, with certain resources likely to be more valuable or strategic to states based on their rarity, concentration, or ease of substitution, based in part on a state's level of development. The results support a fairly uniform role of natural resources, with particular resources and combinations of resources serving to drive low level conflict, but with generally little impact on severe forms of armed conflict. Development also is found to play a role, driving poorer states to dispute natural resources of certain types. Lastly, I return to the topic of conflict over territory with an ethnic dimension by examining the role of issue indivisibility in the negotiations process, and find that negotiated settlements are harder to reach, and states more likely to favor unilateral action when disputing territory with an ethnic or religious component compared to other types of issues in claimed territory.
Physical Literacy and Intention to Play Interscholastic Sports in Sixth Grade Physical Education Students
Authors:   , Farren Gene L.
Published: February 2025

Prevalence of physical inactivity in children and adolescents and the associated epidemic of obesity are increasing concerns. U.S. national health statistics indicate early adolescence (i.e., 10-14 years) appears to be a period of importance regarding physical activity, sedentary behavior, health-related physical fitness, and obesity trends. Considering a significant portion of their waking hours are spent in school, it is widely held that schools' should play a significant role in increasing students' physical activity and health-related physical fitness. To do this, physical education in schools focus on providing quality physical education programs that produce physically literate individuals who have the knowledge, skills, and confidence to enjoy a lifetime of health-producing physical activity. In effect, a call for developing a comprehensive and valid measure of physical literacy has been aptly expressed. Thus, the purpose of this dissertation was to test the psychometric properties of proposed models of physical literacy, examine correlates of the physical literacy factor, and investigate the significance of the relationship between physical literacy and interscholastic sport intention via structural equation modeling. Participants were 400 (231 female, 169 male) sixth-grade physical education students who completed three brief surveys assessing maturation, self-efficacy, self-esteem, knowledge and understanding, motivation, physical activity and sport participation, and interscholastic sport intention. In addition, students completed a sedentary behavior log, a health-related physical fitness assessment, and an overhand throwing skill assessment. Analyses offered overall support for the proposed physical literacy measurement models. Results also supported positive relationship Physical literacy was statistically significantly positively related physical activity and sport team participation, and significantly negatively related and screen-time sedentary behavior. Results also supported a positive path between physical literacy and interscholastic sport intention. The implications of promoting physical literacy within physical education are discussed in light of the three higher-order underlying factors of physical literacy.
Monolith: A Piece for Midi Piano, Mixed Sextet, and Fixed Electronics
Authors:   , Vaughn Mark
Published: February 2025

Reference to a regular pulse is one of the most common ways of measuring time in music. As the basis for tempo, meter, subdivisions, and even formal symmetry, pulse, or the sonic articulation of regular units of time, is found throughout all levels of music. In this paper, I describe how I used a structure of twelve simultaneous pulses to compose "Monolith," a recent piece for MIDI piano, Pierrot ensemble, and fixed electronics. In the first chapter, I contextualize "Monolith" by briefly examining pulse's relationship to hierarchical structure in music and the possibilities for creativity in pulse-based hierarchical structures. In the second chapter, I analyze the use of pulse in Steve Reich's "Music for 18 Musicians," György Ligeti's "Self-portrait with Reich and Riley (with Chopin in the background), and Conlon Nancarrow's "Study No. 36 for Player Piano." In the third chapter, I describe in detail the relationship between the twelve-pulse structure and the various movements that comprise "Monolith," focusing on the relationship between compositional freedom and prescribed structure throughout the work.
How Attitudes towards Statistics Courses and the Field of Statistics Predicts Statistics Anxiety among Undergraduate Social Science Majors: A Validation of the Statistical Anxiety Scale
Authors:   , O'Bryant Monique J.
Published: February 2025

The aim of this study was to validate an instrument that can be used by instructors or social scientist who are interested in evaluating statistics anxiety. The psychometric properties of the English version of the Statistical Anxiety Scale (SAS) was examined through a confirmatory factor analysis of scores from a sample of 323 undergraduate social science majors enrolled in colleges and universities in the United States. In previous studies, the psychometric properties of the Spanish and Italian versions of the SAS were validated; however, the English version of the SAS had never been assessed. Inconsistent with previous studies, scores on the English version of the SAS did not produce psychometrically acceptable values of validity. However, the results of this study suggested the potential value of a revised two-factor model SAS to measure statistics anxiety. Additionally, the Attitudes Towards Statistics (ATS) scale was used to examine the convergent and discriminant validities of the two-factor SAS. As expected, the correlation between the two factors of the SAS and the two factors of the ATS uncovered a moderately negative correlation between examination anxiety and attitudes towards the course. Additionally, the results of a structural regression model of attitudes towards statistics as a predictor of statistics anxiety suggested that attitudes towards the course and attitudes towards the field of statistics moderately predicts examination anxiety with attitudes towards the course having the greatest influence. It is recommended that future studies examine the relationship between attitudes towards statistics, statistics anxiety, and other variables such as academic achievement and instructional style.
A Decision-Making Model for Safe and Effective Use of Functional Analysis Procedures
Authors:   , Vega Gabrielle M.
Published: February 2025

While functional analysis provides the standard methodology for the assessment of problem behavior, procedures still pose potential risk when assessing severe problem behavior. Previous studies have examined several strategies to improve the efficiency of and reduce risks related to the functional analysis process. The purpose of the present series of studies was to replicate and extend previous research on the assessment and treatment of severe problem behavior for one participant diagnosed with an intellectual disability. By incorporating strategies within a systematic decision-making framework, functional analysis procedures were implemented to conduct the assessment of precursors, determine maintaining contingencies for severe problem behavior, and evaluate the effects of a treatment based on the results of a functional analysis.
Seismic Performance Evaluation of Novel Cold-Formed Steel Framed Shear Walls Sheathed with Corrugated Steel Sheets
Authors:   , Lan Xing
Published: February 2025

This thesis presents experiments and numerical analysis of a novel cold-formed steel framed shear wall sheathed with corrugated steel sheets. The objective of this newly designed shear wall is to meet the growing demand of mid-rise buildings and the combustibility requirement in the International Building Code. The strength of the novel shear wall is higher than currently code certified shear wall in AISI S400-15 so that it could be more favorable for mid-rise building in areas that are prone to earthquakes and hurricanes. Full-scale monotonic and cyclic tests were conducted on bearing walls and shear walls under combined lateral and gravity loads. Though the gravity loads had negative effects on the strength and stiffness of the shear wall due to the buckling of the chord framing members, it still shows promise to be used in mid-rise buildings. The objective of numerical analysis is to quantify the seismic performance factors of the newly design shear wall lateral-force resisting system by using the recommended methodology in FEMA P695. Two groups of building archetypes, story varied from two to five, were simulated in OpenSees program. Nonlinear static and dynamic analysis were performed in both horizontal directions of each building archetype. Finally, the results of the performance evaluation verified the seismic performance factors(R=Cd=6.5 and Ω =3.0) were appropriate for the novel shear wall system.

Liquid chromatography-mass spectrometry (LC-MS) based proteomic methods have provided archaeologists with a powerful tool for the discovery and identification of proteins within artifacts. Traditionally, discovery-based methods have utilized a non-targeted full mass scan method in an attempt to identify all proteins present within a given sample. However, increased sensitivity is often needed to target specific proteins in order to test hypotheses. Proteins present within archaeological materials present a unique challenge, as they are often subjected to a variety of chemical transformations both before and after burial. Any preserved proteins will be present within a complex mixture of compounds, and full mass scans often fail to detect less abundant proteins of interest. Consistent and reliable targeted methods are needed to detect protein biomarkers. Taphonomic experimentation was employed as a means to identify the effect of particular processes and conditions on the preservation of mare's milk proteins. In addition, three LC-MS methods were evaluated for their efficiency in identifying mare's milk-specific peptide biomarkers from experimental pottery samples. The ability to reliably detect the presence of these species-specific peptides can help provide evidence about past cultural groups, including the origins of dairying and animal domestication.

"Momentarium" is a collection of poems that examines the instability of moments. By engaging with photography, the poems examine the strengths and flaws in representation. Qualified accuracy, in other words representations that exact no absolute authenticity, are paradoxically, most accurate. The original poems attempt to express both empathy an end to empathy, "I mean to give you what you cannot keep: a blue twice as true" and "I mean to give you what I cannot." The competing forces animate a contingent moment, before it becomes the past.
Best Practices in Targeted Advertising for Fashion Entrepreneurs

Published: February 2025

A key to a business's success is reaching the target market. This ensures that consumers are exposed to the retailer's offerings and by turn, inspired to purchase. In turn, the business can reach its goal of a profitable organization. The purpose of this paper was to determine the most effective fashion advertising appeals for reaching target markets. To address these issues, this thesis consisted of two studies. The purpose of the first study was to determine the advice given to fashion entrepreneurs regarding effective target market practices. The purpose of the second study was to determine effective advertising strategies fashion entrepreneurs may employ for effectively reaching target markets. Data was collected to test the effectiveness of the advice from Study 1, degrees of brand awareness, attitudes towards advertising, willingness to follow trends, purchase intention, purchase behavior, and shopping involvement. The Theory of Reasoned Action was employed as the theoretical framework of the study. The framework was utilized to predict that attitudes towards targeted advertising and pressure to follow fashion trends would positively relate to intent to purchase which, in turn, would positively relate to purchase behavior. The results of this paper concluded the TRA model provided a proper framework to predict purchase behavior from targeted advertising employed by fashion entrepreneurs.
Predictors of Postsecondary Success: An Analysis of First Year College Remediation
Authors:   , Baker Emmett A.
Published: February 2025

This study was a quantitative multiple regression investigation into the relationships between campus factors of high school students graduating in 2013 who immediately enrolled in first-year college freshman level remedial coursework at a large, Central Texas two-year postsecondary institution. The goal of this study was to determine which high school campus-level factors predicted enrollment into college remedial education coursework. The dependent variable was a continuous variable representing the percentage of students from Texas public high school campuses enrolled into at least one student credit hour of remedial education during their first semester as a first-year college student. Eight high school campus-level independent variables were included in the regression model at the campus-level: at risk percentage, economically disadvantaged percentage, limited English proficient percentage, advanced course/dual-enrollment percentage, college ready math percentage, college ready English percentage, ACT average, and SAT average. Pearson correlations and linear regression results were examined and interpreted to determine the level of relationship between the eight selected variables and first-year college student remedial coursework. The multiple regression model successfully explained 26.3% (F(8,286) = 12.74. p < 0.05, r2 = 0.263) of the variance between first-year college students enrolled into remedial coursework at a large, Central Texas two-year postsecondary institution and the campus-level variables from high schools from which they graduated and indicated campus-level economic disadvantaged percentage and campus-level SAT average to be statistically significant at the p < 0.05 level.
Effect of Surface Treatment on the Performance of CARALL, Carbon Fiber Reinforced Aluminum Dissimilar Material Joints

Fiber-metal laminates (FML) are the advanced materials that are developed to improve the high performance of lightweight structures that are rapidly becoming a superior substitute for metal structures. The reasons behind their emerging usage are the mechanical properties without a compromise in weight other than the traditional metals. The bond remains a concern. This thesis reviews the effect of pre-treatments, say heat, P2 etch and laser treatments on the substrate which modifies the surface composition/roughness to impact the bond strength. The constituents that make up the FMLs in our present study are the Aluminum 2024 alloy as the substrate and the carbon fiber prepregs are the fibers. These composite samples are manufactured in a compression molding process after each pre-treatment and are then subjected to different tests to investigate its properties in tension, compression, flexural and lap shear strength. The results indicate that heat treatment adversely affects properties of the metal and the joint while laser treatments provide the best bond and joint strength.
Social Support as a Moderator of Racial/Ethnic Differences in Subclinical Atherosclerosis: The North Texas Heart Study
Authors:   , García James J.
Published: February 2025

This study examined racial/ethnic differences in pre-clinical disease, social support, and tested whether social support was a moderator of racial/ethnic differences in subclinical atherosclerosis. Participants were NHWs, NHBs, and Latinos (n = 283) from the baseline and cross-sectional sample of the North Texas Heart Study. Results from unadjusted models showed no significant racial/ethnic differences for common or bifurcation intima-media thickness (cIMT). However, unadjusted models for cIMT showed a main effect for race/ethnicity F(2, 229) = 3.12, p = .046, partial η2 = .027, with Latinos demonstrating significantly greater internal cIMT compared to NHB but not NHWs. In minimally adjusted models, there was a main effect for race/ethnicity, F(2, 227) = 3.10, p = .047, partial η2 = .027, with significantly greater internal cIMT in Latinos compared to NHBs but not NHWs. In fully adjusted models, racial/ethnic differences in cIMT were attenuated. Contrary to study hypotheses, no racial/ethnic differences in social support were found and social support was not a moderator of racial/ethnic differences in subclinical disease. In the North Texas Heart Study, few racial/ethnic differences emerged, with fully adjusted risk factor models accounting for these differences.
