Published: February 2025

The growing demand for antimicrobial textiles and environmental concerns over synthetic agents have driven interest in biobased agents like chitosan, an eco-friendly alternative reported with variable effectiveness on textiles. This research investigates the effects of chitosan’s molecular weight, concentration, treatment method, and their interaction effects on the antibacterial and physicomechanical properties of cellulosic nonwovens. The role of culture medium dynamics in antibacterial testing was also examined. Chitosan with low (30 kDa), medium (250 kDa) and high (2100 kDa) molecular weights at concentrations of 1 to 15 g/L was applied using pad-dry and dip-dry methods, with dip coating resulting in higher chitosan deposition. Antibacterial activity against Escherichia coli (E. coli) was assessed using three methods: agar diffusion, a luminescent bacterial biosensor assay, and log reduction of colony-forming units (CFU/mL) in a time-kill test. While the first two test methods showed no antibacterial effect, CFU/mL revealed significant activity with interaction effects showing that the dip-coated, 30 kDa chitosan above a concentration of 5 g/L achieved complete bacterial reduction. The enhanced antibacterial performance of chitosan-coated cellulosic substrates, compared to chitosan in a culture medium, highlighted the role of cellulosic nonwoven in boosting antibacterial effectiveness, likely through improved contact and interaction with bacterial cells. The study demonstrated that chitosan-treated cellulosic nonwovens, particularly with dip-dry coating altered tensile strength and increased the bending resistance and bending stiffness.

Authors: Jangir Gauttam , Joshi Nisheeth , Purohit Gaurav
Published: February 2025

Human brain signal processing and finger’s movement coordination is a complex mechanism. In this mechanism finger’s movement is mostly performed for every day’s task. It is well known that to capture such movement EEG or ECoG signals are used. In this order to find the patterns from these signals is important. The BCI competition 4 dataset 4 is one such standard dataset of ECoG signals for individual finger movement provided by University of Washington, USA. In this work, this dataset is, statistically analyzed to understand the nature of data and outliers in it. Effectiveness of pre-processing algorithm is then visualized. The cleaned dataset has dual polarity and gaussian distribution nature which makes Tanh activation function suitable for the neural network BC4D4 model. BC4D4 uses Convolutional neural network for feature extraction, dense neural network for pattern identification and incorporating dropout & regularization making the proposed model more resilient. Our model outperforms the state of the art work on the dataset 4 achieving 0.85 correlation value that is 1.85X (Winner of BCI competition 4, 2012) & 1.25X (Finger Flex model, 2022).

Overconsumption of fructose is linked to metabolic diseases, which are often associated with reduced fertility. GLUT5 is the most specific fructose transporter. To investigate its role in the testes, we analyzed the male reproductive phenotype of transgenic male mice deficient in GLUT5 (GLUT5−/− or GLUT5 knockout [KO] mice). Glut5 expression was shown in Leydig cells and germ cells, from primary spermatocytes to spermatozoa. We found reduced intratesticular fructose and pyruvate concentrations in GLUT5−/− mice. These mice exhibited 30% lower litter sizes compared with control mice. Histological analysis of the testes revealed some seminiferous tubules with a “Sertoli cell-only” phenotype, although spermatogenesis occurred normally in most tubules. Reduced fertility in GLUT5 KO mice was linked to lower sperm production and impaired sperm quality. Spermatozoa from these mice displayed reduced motility, head abnormalities, and a diminished acrosome reaction, which was associated with reduced cyclic adenosine monophosphate content and impaired phosphorylation of protein kinase A substrates in the acrosome. Unexpectedly, androgen production in GLUT5 KO mice was 3-fold higher than in controls, despite unchanged luteinizing hormone levels. Electron microscopy of Leydig cells revealed a highly developed smooth endoplasmic reticulum, increased lipid droplets, and abnormal mitochondrial structures, suggesting disrupted mitochondrial dynamics. Proteomic analysis identified 155 deregulated proteins in the testicular tissue of GLUT5 KO mice, nearly half of which were associated with sperm motility, germ cell morphology, glycolysis, mitochondrial dynamics, and oxidative stress. In conclusion, the absence of the specific fructose transporter GLUT5 reduced testicular fructose content and led to an asthenozoospermia phenotype accompanied by hyperandrogenism.
The Interaction and Mediation of Physical Activity of Body Mass Index with Cardiovascular Disease: evidence from NHANES and MR Analysis
Authors: Zhao Liang , Zhang Danfeng , Zhang Ting , Wang Chunhun , Han Shuo , Zhang Tengfei , He Zhiqing , Wang Junyu
Published: February 2025

Background

Both insufficient physical activity (PA) and excess body weight are important risk factors for cardiovascular disease (CVD), and PA is closely related to body weight. However, it remains unclear whether PA modifies or mediates the association of body mass index (BMI) with CVD.

Methods

We conducted a cross-sectional study of 35,406 adults participating in the National Health and Nutrition Examination Survey (NHANES). The mediation and interaction effects of PA were assessed using a four-way decomposition approach. An additional two-step Mendelian randomization (MR) analysis was performed to verify the potential causal mediation effect.

Results

A strong association was observed between PA and lower odds of CVD after adjusting for all confounders [Odds Ratio (OR): 0.84; 95% Confidence Interval (CI): 0.74–0.95]. Increased BMI was associated with higher odds of CVD (OR: 1.04; 95% CI: 1.03–1.04). PA showed interaction and mediation effects on the association of BMI with CVD. The overall proportion attributable to interaction was -37.5%, while the overall proportion attributable to mediation was 22.2%. MR analysis further confirmed that PA causally mediated the pathway from BMI to CVD.

Conclusions

PA modified the association of BMI with CVD, suggesting that sufficient PA is needed to lower the impact of high BMI on CVD risk. Moreover, we found that PA served as a causal influence on the association of BMI with CVD, indicating that higher BMI led to a lower level of PA, which in turn increased the risk of CVD.
Trajectories of Burden and Depression in Caregivers Following Traumatic Injury: The Role of Resilience
Authors:   , Agtarap Stephanie D.
Published: February 2025

As part of an effort to understand psychological consequences among family members of patients sustaining a traumatic injury, medical research has turned to the role of resilience – or the ability to bounce back from and maintain psychological well-being in the wake of an adverse event— in mitigating the potential distress (i.e., depression and burden) of caregiving (Bonanno, 2004; Roberson et al., under review). This study sought to examine the ability for trait-resilience to predict trajectories of distress over the course of a year among 124 family members and loved ones of patients admitted to a Level I Trauma Center. A cross-lagged path model examining resilience, burden, and depression at baseline, 3, 6, and 12 months after injury showed that, while depression strongly predicted later burden, resilience was not a significant predictor of either outcome in the model. When depression and burden were subjected to a person-centered analysis (i.e., latent growth curve analysis), two major classes were identified: caregivers with high, chronic distress (33% of the sample) and low-moderate distress that declined over time. A three-class solution for caregiver burden further identified a moderate, increasing trajectory class. Predictive discriminant analyses revealed that trait-resilience was a major differentiating trait between class membership (rs = .23 for depression; rs = .32 for burden); further, presence of PTSD symptoms at baseline, gender, and history of depression were shown to be strong factors in distinguishing class membership across both outcomes. This study helps shed insight into the well-being of caregivers in the wake of a loved one's traumatic injury, in addition to possible identifying risk factors while patients are still admitted in the ICU. Lastly, the study provides alternatives for analyses that focus on longitudinal outcomes, particularly person- vs. variable-centered solutions.
Delivery of CRISPR/Cas9 RNAs into Blood Cells of Zebrafish: Potential for Genome Editing in Somatic Cells
Authors:   , Schneider Sara Jane
Published: February 2025

Factor VIII is a clotting factor found on the intrinsic side of the coagulation cascade. A mutation in the factor VIII gene causes the disease Hemophilia A, for which there is no cure. The most common treatment is administration of recombinant factor VIII. However, this can cause an immune response that renders the treatment ineffective in certain hemophilia patients. For this reason a new treatment, or cure, needs to be developed. Gene editing is one solution to correcting the factor VIII mutation. CRISPR/Cas9 mediated gene editing introduces a double stranded break in the genomic DNA. Where this break occurs repair mechanisms cause insertions and deletions, or if a template oligonucleotide can be provided point mutations could be introduced or corrected. However, to accomplish this goal for editing factor VIII mutations, a way to deliver the components of CRISPR/Cas9 into somatic cells is needed. In this study, I confirmed that the CRISPR/Cas9 system was able to create a mutation in the factor VIII gene in zebrafish. I also showed that the components of CRISPR/Cas9 could be piggybacked by vivo morpholino into a variety of blood cells. This study also confirmed that the vivo morpholino did not interfere with the gRNA binding to the DNA, or Cas9 protein inducing the double stranded break.
The Role of Self-Compassion in Posttraumatic Growth
Authors:   , Connally Melissa Londoño
Published: February 2025

Although the experience of trauma is associated with a great deal of psychological distress, it may also lead to meaningful positive change, known as posttraumatic growth (PTG), evidenced as progression in areas of life appreciation, intimacy in relationships, sense of personal strength, new possibilities, and spiritual development. Utilizing an acceptance and commitment therapy (ACT) perspective, the current study explored whether self-compassion helped to explain the willingness to approach and make sense of a trauma, leading to growth. A sample of 758 undergraduate students completed online self-report questionnaires, and results suggested that self-compassion does partially predict PTG and support for how self-compassion may be understood in relation to PTG is provided. Implications of the current study's findings, as well as suggestions for future research related to trauma within a college population, are discussed.
"Reality" while Dreaming in a Labyrinth: Christopher Nolan as Realist Auteur
Authors:   , Cowley Brent
Published: February 2025

This thesis examines how the concept of an auteur (author of a film) has developed within contemporary Hollywood and popular culture. Building on concepts from Timothy Corrigan, this thesis adapts the ideas of the author and the commercial auteur to examine how director Christopher Nolan's name, and film work, has become branded as "realist" by the Hollywood film industry and by Nolan's consistent self-promotion. Through recurring signatures of "realism," such as, cinematic realism (immersive filmic techniques), technical realism (practical effects and actual locations), subjective realism (spectator access to a character's point of view), psychological realism (relatable motivations) and scientific realism (factual science), Nolan's work has become a recognizable and commoditized brand. Like many modern-day auteurs, Nolan himself has been used as a commodity to generate interest to his working methods and to appeal audiences to his studio films. Analyzing each of Christopher Nolan's films along with the industrial and cultural factors surrounding them, a method for understanding contemporary auteurism in Hollywood is presented. Through a consideration of extra-textual components, including promotional featurette's and journalistic interviews with Nolan, as well as his film crew, this thesis will explore how Nolan might be considered a template for a future of auteur branding.
Investigation of the Effect of Functional Units/Connectivity Arrangement on Energy Consumption of Reconfigurable Architectures Using an Interactive Design Framework
Authors:   , Bhargava Arpita
Published: February 2025

Allocation of expensive resources, (such as Multiplier) onto the CGRA has been of interest from quite some time. For these architectural solutions to fulfill the designers' requirements, it is of utmost importance that the design offers high performance, low power consumption, and effective area utilization. The allocation problem is studied using the UntangledII gaming environment, which has been developed at the Reconfigurable Computing Lab at UNT to discover the design of custom domain-specific architectures. This thesis explores several case-studies to investigate the arrangement of functional units and interconnects to achieve a low power, high performance, and flexible heterogeneous designs that can fit for a suite of applications. In the later part, several human mapping strategies of top and bottom players to design a custom domain-specific architecture are presented. Some common trends that were examined while analyzing the mapping strategies of the players are also discussed.
Religiousness and Spirituality: How Are They Related to Moral Orientations?
Authors:   , Gabhart Elizabeth A.
Published: February 2025

This dissertation examines correlations between religiousness and spirituality, to moral orientations using moral foundations theory as a framework. Using the 2012 Measuring Morality dataset, which provides a representative sample of the population of the United States, I create linear regressions which test associations between religiousness, spirituality, and each of the five moral foundations ((harm/care, fairness, in-group loyalty, respect for authority, and purity). I find that religiousness is negatively associated with concern for harm, and positively associated with respect for authority, a finding which implies that the moral behavior of religious people is rooted in respect for authority more than in any other moral concern. Spirituality is positively associated with concern for fairness. The implications of all findings are discussed, as well as limitations and recommendations for future research.

A Selective Lineage of Mexican Bassoonists
Authors:   , Cruz Jorge
Published: February 2025

Spanish settlers brought the precursor to the bassoon, el bajón, to Mexico in the late sixteenth century. Documentation of the bassoon was intermittently from the sixteenth century on, the current playing traditions were not established until the second half of the twentieth century. Bassoon education in Mexico flourished in the 1970's because several bassoonists became expatriates, and chose to live and work in Mexico for the entirety of their careers. Two major pedagogues, Lazar Stoychev and Jerzy Lemiszka paved the way for the current Mexican bassoon community. This dissertation presents a selective lineage of bassoonists who have held positions in major Mexican orchestras and universities since the mid-twentieth century. The purpose of this study is to recognize the contributions these players and teachers have given to the bassoon world. In recent years, Mexican bassoonists have commissioned hundreds of works for the bassoon and this significant achievement has placed the Mexican bassoon community in an upward trajectory. To place these players in proper historical context, a brief history of classical music institutions in Mexico since the sixteenth century is given. This dissertation documents the history and pedagogy of recent bassoonists in Mexico via a cohesive family tree.
Synthesis and Application of New Chiral Ligands for Enantioselectivity Tuning in Transition Metal Catalysis
Authors:   , Kong Fanji
Published: February 2025

A set of five new C3-symmetric phosphites were synthesized and tested in palladium-catalyzed asymmetric Suzuki coupling. The observed reactivity and selectivity were dependent upon several factors. One of the phosphites was able to achieve some of the highest levels of enantioselectivity in asymmetric Suzuki couplings with specific substrates. Different hypotheses have been made for understanding the ligand effects and reaction selectivities, and those hypotheses were tested via various methods including DOSY NMR experiments, X-ray crystallography, and correlation of catalyst selectivity with Tolman cone angles. Although only modest enantioselectivities were observed in most reactions, the ability to synthesis these phosphites in only three steps on gram scales and to readily tune their properties by simple modification of the binaphthyl 2´-substituents makes them promising candidates for determining structure-selectivity relationships in asymmetric transition metal catalysis, in which phosphites have been previously shown to be successful. A series of novel chiral oxazoline-based carbodicarbene ligands was targeted for synthesis. Unfortunately, the chosen synthetic route could not be completed due to unwanted reactivity of the oxazoline ring. However, a new and efficient route for Pd-catalyzed direct amination of aryl halides with oxazoline amine was developed and optimized during these studies. Chiral binaphthyl based Pd(II) ADC complexes with different substituent groups have been synthesized and tested in asymmetric Suzuki coupling reactions. Although only low enantioselectivities were observed in Suzuki coupling, this represents a new class of chiral metal-ADC catalysts that could be tested in further catalytic.
The Impact of Observational Learning on Physical Activity Appraisal and Exertion Following Experimental Back Injury and the Role of Pain-Related Fear
Authors:   , Guck Adam J.
Published: February 2025

Chronic low back pain (CLBP) is one of the most prevalent and disabling health conditions in the US and worldwide. Biomedical explanations of acute injury fail to account for why some individuals experience remission of pain and restoration of physical function while others do not. Pain-related fear, accompanied by elevated appraisals of physical exertion and avoidance of physical activity, has emerged as a central psychosocial risk factor for transition from acute injury to chronic pain and disability. Research has indicated that these pain-related factors may be maintained through observational learning mechanisms. To date, no studies have experimentally examined the role of observational learning and pain-related fear in the context of actual musculoskeletal injury. Accordingly, the present study examined the impact of observational learning and pain-related fear on activity appraisals and exertion following experimentally- induced acute low back injury. Healthy participants' appraisal of standardized movement tasks along with measures of physical exertion were collected prior to and following a procedure designed to induce delayed onset muscle soreness (DOMS) to the lower back. Following induction of DOMS, participants observed a video prime depicting CLBP patients exhibiting either high or low pain behavior during similar standardized movements. In line with hypothesized effects, participants assigned to the high pain behavior prime demonstrated greater elevation in pain and harm appraisals as well as greater decrement in physical exertion. Further in line with hypotheses, significant changes in appraisal and physical performance following the high pain behavior prime were only observed among participants endorsing high pain-related fear during baseline assessment. Discussion of findings addresses potential mechanisms of action as well as study limitations and direction for future research.
A Convergence Analysis of LDPC Decoding Based on Eigenvalues
Authors:   , Kharate Neha Ashok
Published: February 2025

Low-density parity check (LDPC) codes are very popular among error correction codes because of their high-performance capacity. Numerous investigations have been carried out to analyze the performance and simplify the implementation of LDPC codes. Relatively slow convergence of iterative decoding algorithm affects the performance of LDPC codes. Faster convergence can be achieved by reducing the number of iterations during the decoding process. In this thesis, a new approach for faster convergence is suggested by choosing a systematic parity check matrix that yields lowest Second Smallest Eigenvalue Modulus (SSEM) of its corresponding Laplacian matrix. MATLAB simulations are used to study the impact of eigenvalues on the number of iterations of the LDPC decoder. It is found that for a given (n, k) LDPC code, a parity check matrix with lowest SSEM converges quickly as compared to the parity check matrix with high SSEM. In other words, a densely connected graph that represents the parity check matrix takes more iterations to converge than a sparsely connected graph.
Fabrication of Photonic Crystal Templates through Holographic Lithography and Study of their Optical and Plasmonic Properties in Aluminium Doped Zinc Oxide
Authors:   , George David Ray
Published: February 2025

This dissertation focuses on two aspects of integrating near-infrared plasmonics with electronics with the intent of developing the platform for future photonics. The first aspect focuses on fabrication by introducing and developing a simple, single reflective optical element capable of high–throughput, large scale fabrication of micro- and nano-sized structure templates using holographic lithography. This reflective optical element is then utilized to show proof of concept in fabricating three dimensional structures in negative photoresists as well as tuning subwavelength features in two dimensional compound lattices for the fabrication of dimer and trimer antenna templates. The second aspect focuses on the study of aluminum zinc oxide (AZO), which belongs to recently popularized material class of transparent conducting oxides, capable of tunable plasmonic capabilities in the near-IR regime. Holographic lithography is used to pattern an AZO film with a square lattice array that are shown to form standing wave resonances at the interface of the AZO and the substrate. To demonstrate device level integration the final experiment utilizes AZO patterned gratings and measures the variation of diffraction efficiency as a negative bias is applied to change the AZO optical properties. Additionally efforts to understand the behavior of these structures through optical measurements is complemented with finite difference time domain simulations.
Professional Learning Communities: A Comparative Case Study of Shared Personal Practice
Authors:   , Curtis Anna E.
Published: February 2025

Effective instructional practice has a significant impact on student learning. Shared personal practice within a professional learning team (PLT) is one of the key elements in consistently improved instructional practice. However, this PLT characteristic is often the least evident and the hardest to absorb into PLT culture. This study examined the relational characteristics, facilitating factors, or barriers to shared personal practice within a PLT. Two PLTs in core subject areas across two Texas high school campuses were included in this comparative case study. Data from document analysis, PLC observations, focus group interviews, and in-depth individual interviews were examined thematically to answer the research questions guiding this study. The results of this study revealed that building strong relationships and an emphasis on collective creativity were strong predictors of sharing personal practice. Collective clarity on PLT practices and the purpose of sharing personal practice increased the success and occurrence of sharing personal practice. The results also revealed that the copious tasks of teaching and negative perceptions of being observed by colleagues hindered consistent sharing of personal practice. This study describes the current context of shared personal practice as a foundation for future studies to examine how practice can be transformed.
Developing a Self-Respect Instrument to Distinguish Self-Respect from Self-Esteem
Authors:   , Jefferson Sean G.
Published: February 2025

Throughout the scientific literature, researchers have referred to self-respect and self-esteem as being the same construct. However, the present study advocated that they exist as two distinct constructs. In this quantitative study, an instrument was developed to measure self-respect as a construct, and subsequently distinguish that self-respect is distinct from the construct of self-esteem. Exploratory factor analyses (EFA) indicated 32.60% of the variance was accounted for by the 11-item Jefferson Self-Respect instrument (JSR), which measured self-respect as a unidimensional construct. The reliability estimate of the scores from the JSR reached an acceptable α = .82. Fit indices (RMSEA = .031, SRMR = .037, CFI = .982, and TLI = .977) from the confirmatory factor analyses (CFA) signified a well-fitted hypothesized model of self-respect that existed as a unidimensional construct. Additionally, the CFA revealed that the construct of self-respect, and self-esteem was generally distinct, and the strength of the correlation between the two constructs was moderately positive (r = .62).
Stigma and Psychological Quality of Life in People Living with HIV: Self-Esteem as a Mediating Factor
Authors:   , Wike Alexandra Elizabeth
Published: February 2025

Although the negative impact of HIV stigma is well documented, a gap exists in exploration of constructs that mediate the relationship between HIV stigma and psychological QOL (PQOL). Self-esteem is often conceptualized as a protective factor. We used PLS-SEM to explore the relationships between HIV stigma, PQOL and self-esteem, where PQOL and self-esteem are latent constructs represented by direct observations. Our hypotheses were supported - stigma is negatively related to self-esteem (as measured by self-blame, forgiveness of self, acceptance without judgment and self-esteem), self-esteem is positively related to PQOL (as measured by depression, mental health, QOL and perceived stress) and when the two aforementioned relationships are controlled for, a previously significant relation between stigma and PQOL changes its value significantly. These findings have implications for interventions designed to mitigate the negative psychosocial effects of stigma in PLH.
An Engagement Bout Analysis of the Effects of Effort
Authors:   , Moore Alyssa N.
Published: February 2025

Operant response rate can be viewed as bouts, periods of alternating engagement and disengagement with ongoing schedules of reinforcement. Relatively few studies have examined the role of force and effort on engagement bouts. Moreover, those examining effort have used switch closure devices to define the response. Switch closures tend to overestimate the effect of effort because increasing the force requirement excludes low-force responses that previously activated the switch. In the present study, we examined the effects of effort using a force transducer, which allows us to record criterion responses that meet the force requirement and subcriterion responses that do not. The current study was conducted using four male Sprague Dawley rats. Each rat was run through a series of four conditions, each with a different combination of variable interval schedules (VI 30s, VI 120s) and force requirements (5.6g, 32g). Log survivor analyses of bout structure showed that increased force requirements decreased the rate of bout initiations. Additionally, when log-survivor functions were computed using only criterion responses, shifts in the function were less extreme than when all measured responses were used; the latter finding suggests exclusion of "subcriterion" responses in prior work has overestimated the effects of force on bout structure
How Exposure to Parental Intimate Partner Violence Affects College Students' Dating Violence: A Structural Equation Model with Adult Attachment and Social Information Processing as Mediating Factors
Authors:   , Chong Chu Chian
Published: February 2025

The effects of childhood exposure to parental intimate partner violence (EPIPV) on dating violence (DV) were examined through two layers of mediations. Based on attachment theory, individuals who are exposed to parental intimate partner violence are less likely to experience secure parent-child attachment, which in turn transfers to insecure adult attachment that is prone to perceive significant others as less trustworthy and less reliable as well as higher likelihood of over-reacting and/or staying in an unhealthy relationship. In the second layer of mediation, insecure adult attachment would lead to biased SIP which in turn, would result in an increase of DV. A total of 327 university students participated in the study by voluntarily completing the research questionnaires. Among them, 253 reported having experienced mild to severe DV and were included in the final data set. The data analyses procedures included examinations of the measurement models and structural equation modeling (SEM) analyses. Findings from the final models best supported by the data indicated that EPIPV predicted both dating violence perpetration and victimization and that EPIPV predicted adult attachment anxiety and avoidance, both of which are consistent with existing literature. However, findings revealed that EPIPV did not predict SIP and SIP was not predictive of DV perpetration. In addition, neither adult attachment anxiety nor attachment avoidance was predictive of DV perpetration and victimization. For DV victimization SEM model, adult attachment anxiety predicted SIP, however, SIP did not predict DV victimization. Findings are discussed based on DV literature and attachment theory. Limitations, clinical implications, and future research directions are also outlined.
Selected Works by Female Composers of the Nineteenth and Twentieth Centuries for Advanced Suzuki Violin Students
Authors:   , Edelman Rhea
Published: February 2025

The intent of this dissertation is to identify and analyze several pieces by female composers that are technically suitable for the specific development of an advanced Suzuki violin student studying in Suzuki books 7 or 8. The selected pieces can then be used by trained Suzuki teachers, in conjunction with the male-composer-dominated Suzuki repertoire, to enhance students' technical development while also increasing their well-rounded musicianship by exposing them to female composers. The development of off-the-string bow strokes, string crossings, shifting, left-hand articulation and musical expression will be traced through the first six volumes of the Suzuki repertoire in order to understand a Suzuki student's expected abilities pertaining to these technical elements when beginning the repertoire in books 7 and 8. Pieces by female composers highlighting and enhancing the referenced techniques will be identified and analyzed in a similar manner. These pieces will be compiled into a document for Suzuki students and teachers to use, along with appropriate editorial markings and biographies of the composers. This document can be an inspirational supplement to Suzuki students' musical development and help develop an awareness of female composers.
Self-Enhancement Processes in Couples
Authors:   , Reyna Samuel H.
Published: February 2025

Self-enhancement is a process by which individuals misperceive themselves by viewing themselves in a positively biased manner. Past research indicates that self-enhancement can have both positive and negative effects on romantic relationships. The purpose of this dissertation was to explore the role of self-enhancement in unmarried dating couples (N = 124 couples; 248 individuals) with respect to conflict, dyadic adjustment, causal and responsibility attributions, and possible moderators between self-enhancement and dyadic adjustment. The results are organized in four sections. First, I found a curvilinear relationship between participant self-enhancement and conflict. At very low and very high levels of self-enhancement there were increased levels of conflict. Second, participant self-enhancement was positively associated with positively associated with increased participant dyadic adjustment, but there was no relationship between participant self-enhancement and partner dyadic adjustment. Third, there was no relationship between participant self-enhancement and causal and responsibility attributions. Fourth, forgiveness and commitment did not moderate the relationship between self-enhancement and dyadic adjustment; however, there were main effects for both forgiveness and commitment - both forgiveness and commitment were positively associated with dyadic adjustment. I conclude by discussing limitations, areas of future research, and implications for counseling.
A Guide to Suitable Bass Solo Vocal Repertoire by J. S. Bach for Collegiate Baritone
Authors:   , Chang Chul Woong
Published: February 2025

In the Baroque period, the baritone voice was not yet well-defined, but many composers wrote vocal pieces with a range appropriate for the modern baritone voice. Composers used the general categories of soprano, alto, tenor, and bass for solo voice in their compositions. Johann Sebastian Bach (1685-1750) was no different from other Baroque composers in writing solo works to be performed by one of the four main voice types. The various ranges and tessituras of J. S. Bach's vocal works for bass solo voice are not limited to being sung by low basses, but may also be sung by more medium ranged baritones. The purpose of this research is to guide collegiate voice teachers and their baritone students in selecting appropriate repertoire from the works of Bach on the basis of each students' level of development and to categorize four groups of bass solos by Bach for collegiate baritone students: beginning level for freshmen, intermediate level for sophomores, advanced level for juniors and seniors, and pre-professional level for seniors and graduate students. This research was prepared in conjunction with a DMA lecture-recital of eight bass solos for collegiate baritone voice, selected from the study; two vocal works for each proficiency level.

Published: February 2025

The purposes of this descriptive survey research study were (a) to describe novice band directors' perceptions of the importance of skills/knowledge used n effective music teaching, (b) to describe novice band directors' perception of the difficulty of acquiring each skill or knowledge component, (c) to compare novice band directors' perceptions of the importance and difficulty of the skills/knowledge used in their classrooms, (d) to describe ways that novice band directors perceived university coursework as helpful in acquiring teaching skills/knowledge, and (e) to describe improvements to university coursework that novice band directors perceived could help future band directors. The personal skills/knowledge category (M = 4.64) was rated highest for importance, followed by the teaching (M = 4.60) and musical (M = 4.29) categories. Additionally, participants rated the personal skills/knowledge category (M = 3.57) as the easiest to acquire, followed by musical (M = 3.14), and teaching (M = 3.09) categories. There was a statistically significant difference between teaching importance ratings and teaching acquisition ratings, with the teaching importance category rated higher by participants. Participants perceived secondary instrument instruction, teaching experiences, core music curriculum, and practical skills/knowledge as positive aspects of university coursework. Finally, secondary instrument instruction, field experiences, non-instructional aspects of teaching, and musical pedagogy were reported by participants as areas for possible improvement.
Controlled Vocabularies in the Digital Age: Are They Still Relevant?
Authors:   , Baker William Andrew
Published: February 2025

Keyword searching and controlled vocabularies such as Library of Congress subject headings (LCSH) proved to work well together in automated technologies and the two systems have been considered complimentary. When the Internet burst onto the information landscape, users embraced the simplicity of keyword searching of this resource while researchers and scholars seemed unable to agree on how best to make use of controlled vocabularies in this huge database. This research looked at a controlled vocabulary, LCSH, in the context of keyword searching of a full text database. The Internet and probably its most used search engine, Google, seemed to have set a standard that users have embraced: a keyword-searchable single search box on an uncluttered web page. Libraries have even introduced federated single search boxes to their web pages, another testimony to the influence of Google. UNT's Thesis and Dissertation digital database was used to compile quantitative data with the results input into an EXCEL spreadsheet. Both Library of Congress subject headings (LCSH) and author-assigned keywords were analyzed within selected dissertations and both systems were compared. When the LCSH terms from the dissertations were quantified, the results showed that from a total of 788 words contained in the 207 LCSH terms assigned to 70 dissertations, 246 of 31% did not appear in the title or abstract while only 8, or about 1% from the total of 788, did not appear in the full text. When the author-assigned keywords were quantified, the results showed that from a total of 552 words from304 author-assigned keywords in 86 dissertations, 50 or 9% did not appear in the title or abstract while only one word from the total of 552 or .18% did not appear in the full text. Qualitatively, the LCSH terms showed a hierarchical construction that was clearly designed for a print card catalog, seemingly unnecessary in a random access digital environment. While author-assigned keywords were important words and phrases, these words and phrases often appeared in the title, metadata, and full text of the dissertation, making them seemingly unnecessary in a keyword search environment as they added no additional access points. Authors cited in this research have tended to agree that controlled vocabularies such as LCSH are complicated to develop and implement and expensive to maintain. Most researchers have also tended to agree that LCSH needs to be simplified for large, full text databases such as the Internet. Some of the researchers have also called for some form of automation that seamlessly links LCSH to subject terms in a keyword search. This research tends to confirm that LCSH could benefit from simplification as well as automation and offers some suggestions for improvements in both areas.
Saudi Mothers' Perspectives on the Influence of Acculturation on their Childrearing Beliefs and Behaviors of their Children
Authors:   , Kherais Walaa A.
Published: February 2025

There are a considerable number of Saudi Arabian students who attend U.S. schools. To date, no published studies exist that relate to the Saudi Arabian students, their families, and how they acculturate to the American society. Acculturation affects parents and children in different ways, and it can affect the way parents raise their children. Using semi–structured interviews, this study examined Saudi mothers' perspectives on acculturation to American society and how those perspectives affect their childrearing beliefs and their children's behaviors. The descriptive qualitative study acknowledges mothers' perceptions about adaptation of Saudi children to American society and if those parents observe behavioral changes in their children. The results showed there are some changes that occurred regarding parental beliefs of parents due to acculturation, but there were not any behavioral problems caused by acculturation to the American culture in the Saudi children.

The Relationship between Teacher Attrition and Student Achievement in Reading among Middle School Students
Authors:   , Perkins Gwendolyn Moseley
Published: February 2025

The purpose of this study was to determine whether a significant relationship existed between teacher attrition and student success in middle school reading by conducting a quantitative analysis. Additionally, the inclusion of school demographic characteristics were included in the model to consider previous findings referencing the challenges schools face in attracting and retaining teachers in low performing urban schools with high populations of economically disadvantaged and minority students. In this analysis, the relationship between teacher attrition and student achievement in middle school as measured by the State of Texas Assessments of Academic Readiness (STAAR) for reading among middle school students in Grades 6, 7, and 8, as reported on the Texas Academic Performance Reports (TAPR), were examined. The regression models used to analyze the three research questions addressed in the study include an examination of teacher attrition on campus pass rates, and grade level pass rates for sixth, seventh, and eighth grades as measured by the STAAR Reading assessment. The data utilized in this study were collected from seven North Texas middle schools in a fast growth school district together with their comparable campuses as identified by the Texas Education Agency for the school years 2013-2014 through 2015-2016. The results of the analysis indicate teacher attrition accounts for a significant variance in STAAR Reading pass rates among middle school students. Additionally, the school demographic characteristics defined as percentage economically disadvantaged, percentage English language learners, mobility rates, and percentage white students account for 83.4% of the variance in the average campus pass rates for STAAR Reading when combined.
Teaching Behavior Professionals to Use the Interview-Informed Synthesized Contingency Analysis (IISCA): A Preliminary Investigation
Authors:   , Metras Rachel L.
Published: February 2025

We assessed the implementation accuracy and fidelity of two board certified behavior analysts (BCBAs) using the open-ended interview from Hanley. Participants interviewed a confederate using the open-ended interview, and were then asked to use information gathered from the interview to create operational definitions of target behaviors as well as test and control condition procedures for a subsequent matched test-control functional analysis as is characteristic of the interview-informed synthesized contingency analysis (IISCA) strategy. Brief behavioral skills training (BST) was then implemented with all participants to increase the accuracy of constructing both target behavior definitions and functional analysis procedures. Preliminary results show moderate rates of accuracy of target behavior definitions and functional analysis procedures prior to BST, and high rates of accuracy following BST. The results also suggest high implementation fidelity on the open-ended interview may not be necessary to achieve high accuracy when constructing target behavior definitions and functional analysis procedures.
Kinetic Study of the Reactions of Chlorine Atoms with Fluoromethane and Fluoromethane-d3 in the Gas Phase
Authors:   , Shao Kejun
Published: February 2025

The kinetics of the gas-phase reactions of chlorine atoms with fluoromethane (CH3F) and fluoromethane-d3(CD3F) were tested experimentally. The relative rate method was applied by using CH4 as the reference compound for fluoromethane (CH3F) and CH4 and CH3F as the reference compound for fluoromethane-d3(CD3F). The rate constants for H-abstraction from CH3F and D-abstraction from CD3F were measured at room temperature and a total pressure of 920 Torr using Ar as a diluent. The rate constants are described by the expressions: kH= (3.50±0.52) x 10-13 cm3 molecule-1 s-1 and kD=(5.0±0.51) x 10-14 cm3 molecule-1 s-1. The kinetic isotope effect, equal to the ratio kH/kD, was found to be 7.0±1.2 at room temperature.

This is a collection of two stories, one fiction and one non-fiction, in communication with one another. Both stories explore how trauma can transform a life. In "Tabula Rasa," Mena is unable to recall her past after being beaten and left for dead. She must choose whether to uncover her past or forget it and move forward with her life. Set in a town run by witches, Mena learns that both choices are dangerous. In "Eternal Second," the narrator recounts the aftermath of her husband's suicide. She explores how trauma invades all aspects of her life. In both stories, women must navigate a new life created by the destruction of the old one.
Development and Analysis of a Mobile Node Tracking Antenna Control System
Authors:   , Hensley Phillip H.
Published: February 2025

A wireless communication system allows two parties to exchange information over long distances. The antenna is the component of a wireless communication system that allows information to be converted into electromagnetic radiation that propagates through the air. A system using an antenna with a highly directional beam pattern allows for high power transmission and reception of data. For a directional antenna to serve its purpose, it must be accurately pointed at the object it is communicating with. To communicate with a mobile node, knowledge of the mobile node's position must be gained so the directional antenna can be regularly pointed toward the moving target. The Global Positioning System (GPS) provides an accurate source of three-dimensional position information for the mobile node. This thesis develops an antenna control station that uses GPS information to track a mobile node and point a directional antenna toward the mobile node. Analysis of the subsystems used and integrated system test results are provided to assess the viability of the antenna control station.
