A Mixed Method Approach: The Influence of Military Identity on Person-Organization Fit and Organizational Commitment, and a Proposed System of Military to Civilian Employment Transition
Authors:   , Doyle Alaina M.
Published: December 2023

The evaluation of the transition experiences of veterans to civilian life was conducted. The military to civilian transition (MCT) framework along with theories covering organizational, identity, and systems streams of research situated the study. A mixed methods approach was conducted in two phases: a 28-item survey and 1.5-hour interviews, which helped contextualize and explain survey findings. The multiple regression procedure examined the relationship among three variables: person-organization fit, military identity, and organizational commitment with military identity was included as a moderator. Results indicated a positive relationship between person-organization fit and organizational commitment. Contrariwise, results indicated military identity's relationship between the variables was found to be not statistically significant. Although the moderation effect of military identity was not found to influence the relationships, interviews with veterans indicated a strong connection to their military identity. Veterans shared negative and unpredictable transition stories, positive transition stories, feelings of isolation, and held prevailing military goals, while reporting a lack of backing from support agencies. Veterans perceived differences between the military and civilian environments, veteran turnover and organizational commitment were found to connect and military values and military identity were found to have connections as well. Recommendations for improving military to civilian setting transitions for veterans, civilians, and support agencies are presented. A new system of transition is proposed with the intention of improving the veteran experience as they enter the workforce. Future research and limitations to the research outcomes are also supplied.
Near-Infrared Spectroscopy of High Redshift Quasars: Bringing Distant Quasars into View
Authors:   , Dix Cooper Wilhelm
Published: December 2023

The Gemini Near Infrared Spectrograph - Distant Quasar Survey (GNIRS-DQS) is the largest uniform, homogeneous survey of its kind, covering 260 quasars at 1.5 ≤ z ≤ 3.5. This unique survey, coupled with data from the Sloan Digital Sky Survey (SDSS), enables new investigations into redshifts, supermassive black hole masses (MBH), and accretion rates at high redshift through spectroscopic coverage of important rest-frame UV-optical emission lines. The importance of this survey is highlighted in the fact that the optical emission lines provide more reliable measurements of these quasar parameters than their UV counterpart. With such a unique sample compiled here, I construct prescriptions to calibrate these quasar parameters derived from rest-frame UV emission lines to those derived from rest-frame optical emission lines. These prescriptions provide important insight into how these parameters depend on redshift and are potentially biased as we look out further into the universe. Additionally, all the work completed with this sample will help shape our understanding of how these quasars and their host galaxies co-evolve over cosmic time.
Nothing Short of Really Healthy Children: Mothers, the Children's Bureau, and Disability, 1914 - 1933
Authors:   , Edsall Brooke C.
Published: December 2023

In 1931 the United States Children's Bureau asserted that "nothing short of really healthy children should satisfy parents." This thesis examines how literature published by the Children's Bureau from 1913 to 1933 shaped perceptions of motherhood and of maternal control over the body. As the bureau taught mothers how to care for their children, it also taught them that by following bureau advice, mothers could shape the bodies of their children to adhere to normative body standards. The research considers the relationship between mothers, the state, and the physical body. This thesis is divided into chapters about prenatal care and maternal marking; infant care and maternal policing; and child care and maternal control.
Professional Learning Communities and the Supportive Conditions for Improved Teacher Instructional Practices
Authors:   , Parham Charlene Marie
Published: December 2023

The purpose of the study was to examine and evaluate the extent to which the supportive conditions (collaboration, teacher efficacy, shared leadership, and trust) were present in the district's current professional learning communities (PLCs) model, and whether teachers perceived the supportive conditions to be related to improving their instructional practices. This mixed-methods study used Pearson correlation coefficient, multiple regression, and focus group interviews to concurrently triangulate data to answer the research questions. The sample from this study was identified from 600 middle school teachers. Survey participants included 139 teachers and each of the four focus group interviews contained 6 teachers for a total of 24 teachers. Of the four supporting conditions analyzed, trust generated the highest mean (M = 3.41). Results from this study indicate that the supportive conditions for PLCs have a strong correlation (0.10) with the studied district's current PLC model and each specific supporting condition elicits a targeted aspect of professional learning that has a significant impact on teacher instructional practices. Recommendations for future studies include the expansion of this study to include elementary and high school participants and to extend this study to a larger scope of interested districts seeking to improve their PLC structures for improved teacher instructional practices. Expanding this research could build upon the current body of literature as it relates to PLCs, professional learning, and student achievement.
Suppression of Higher Acoustic Harmonics by Application of Solid-Solid Periodic Layered Structure in Nonlinear Ultrasonics Nondestructive Evaluation Field
Authors:   , Kang Jinho
Published: December 2023

Nondestructive testing (NDT) using ultrasound band 1-5 MHz, has been widely used for the early-stage detection of structural failure; however, it fails to detectf material degradation, fatigue, and microcracks. NDT with nonlinear ultrasound (NLU) can detect a microscopic discontinuity or imperfection that may be a source of the second harmonic in the reflected signal. In this research, we focus on creating a metamaterial band filter that filters out nonlinearities induced by the instrument itself. A 1D elastic superlattice (SL) acoustic filter is designed with a bandgap in its frequency spectrum that covers the frequency range of second harmonic. The SL is made of periodically alternating Cu and Sn-Pb solder layers. We conducted analytical and numerical calculations to obtain the appropriate thickness of each layer. The metamaterial in this study has the pass band for the fundamental frequency of 5 MHz and the first stop band centered near the frequency of 10 MHz; 5 MHz was chosen because the second harmonic at 10 MHz can detect 200μm micro-scale damage. Experiments with aluminum as the reference specimen and with SL filter were conducted. A function-generator generates 3 pulses sine signal, within the frequency range from 2.5 MHz to 20MHz. Spectral analysis of the signal through the SL filter shows 100 times voltage suppression of the second harmonic as compared to the signal transmitted through the Al specimen. By filtering out the device's inherent nonlinearity with the SL ultrasonic filter, one can detect microcracks, fatigue and material degradation with much higher accuracy.
The First Lady of Washington City: Margaret Bayard Harrison Smith, Family, and Politics in the Early Republic
Authors:   , Thweatt William Denton
Published: December 2023

Margaret Bayard Harrison Smith was a prominent member of early Washington City society from the time she and her husband, Samuel Harrison Smith, moved to the blossoming capital in 1800 until her death in 1844. As a longtime resident of Washington, Margaret spent most of her adult life navigating the unique socio-political waters of the capital and developing friendships with many of the most prominent politicians of her time. Mrs. Smith's writings provide firsthand accounts of several important political events including Congress' role in the election of 1800, Jefferson's first inauguration, Madison's first inauguration, and the destruction left by the British after the siege of Washington. Her writings also provide a picture of early undeveloped Washington City, where grand public buildings were largely surrounded by wilderness and connected by muddy roads. While this work looks at the social and political environment that Margaret Smith experienced, it also examines many of the personal concerns that frequented Mrs. Smith's writings. Margaret's views on educating her children, interacting with servants, interacting with the enslaved population of Washington, and dealing with feelings of isolation, due to the distance from her family, are frequently addressed in her letters. Focusing on these aspects of Mrs. Smith's writings allows for a greater examination of the societal norms of her day about gender, class, and race. While Margaret's letters and commonplace books have often been used to examine Washington society and the lives of her prominent friends, there is no biography of Mrs. Smith herself. This dissertation provides the first biography of Margaret Bayard Harrison Smith from her birth until the end of the War of 1812.
Supporting and Retaining Beginning Teachers during COVID-19
Authors:   , Shuffield Austin
Published: December 2023

This explanatory sequential mixed methods study was designed to determine, from the perspective of beginning teachers, the extent to which the COVID-19 pandemic affected their intentions to remain in teaching. There were two additional goals in conducting the study: (a) to determine the key practices, supports, or events that played a role in impacting teachers' intentions to remain in teaching during a crisis; and (b) to determine the key practices, supports, or events teachers believe the district or school could do that might further impact their intention to remain in teaching during a crisis. In Phase 1, a survey was administered to teachers who began employment in the studied district in academic years 2018, 2019, 2020, and 2021. In Phase 2, a semi-structured focus group interview was conducted with volunteer participants who had taken the survey to develop a deeper understanding of the patterns observed from the survey responses. While this study was designed to determine the impact of the COVID-19 pandemic on teachers' intentions to remain in teaching, a statistically significant result was not identified. This study identified practices, supports, and events that impacted beginning teacher retention, focusing on what was effective, ineffective, and could have been added to increase effectiveness. Beginning teachers self-identified that mentorship within their subject and grade level, salary and benefit increases, and supportive cultures were helpful in retention. In contrast, strategies deemed ineffective included a lack of preparation for the challenges that they faced and impractical professional development. Beginning teachers explained that retention might have been increased if school leaders allowed greater opportunities for networking, as well as a greater focus on training teachers in technology and software systems for classroom use.

On Sharp Permutation Groups whose Point Stabilizers are Certain Frobenius Groups
Authors:   , Norman Blake Addison
Published: December 2023

We investigate non-geometric sharp permutation groups of type {0,k} whose point stabilizers are certain Frobenius groups. We show that if a point stabilizer has a cyclic Frobenius kernel whose order is a power of a prime and Frobenius complement cyclic of prime order, then the point stabilizer is isomorphic to the symmetric group on 3 letters, and there is up to permutation isomorphism, one such permutation group. Further, we determine a significant structural description of non-geometric sharp permutation groups of type {0,k} whose point stabilizers are Frobenius groups with elementary abelian Frobenius kernel K and Frobenius complement L with |L| = |K|-1. As a result of this structural description, it is shown that the smallest non-solvable Frobenius group cannot be a point stabilizer in a non-geometric sharp permutation group of type {0,k}.
How Receiving Communities Structure Refugee Settlement Experiences: The Case of Burmese Immigrants in DFW
Authors:   , Stewart Kaitlin Victoria
Published: December 2023

The Dallas-Forth Worth Metroplex (DFW) serves as a diverse resettlement location for globally displaced refugees. While research examines how the nation impacts refugee resettlement, studies that examine the role of the city and community in placemaking are still lacking. In city resettlement investigations, research often focuses broadly on advocacy and political movements rather than the impacts of local-level structures and policies. In this paper, I develop an evaluation model using Jenny Phillimore's categories for successful refugee resettlement that examines how structural barriers, community interactions, and resource accessibility affect space and place for refugee populations. Through an ethnography of Chin and Rohingya refugee communities in DFW, I explore the differences between community-settled and state-settled refugee groups and the idea of an integrated resettlement program. Additionally, I argue that refugees who choose their settlement location in the United States are empowered and thus have a stronger connection to their host community than state-settled refugees. For example, in interviews, the Chin emphasized their ownership of Lewisville and feelings of home, while the Rohingya expressed feelings of placelessness and dispossession in Dallas. As governments push towards an entirely privatized system of refugee resettlement, this research argues for an integrated method that draws upon federal resources and community connections. Through the experiences of Lewisville's Chin community, this research demonstrates the potential of such a program in the United States.
Bridging the Gap between a Healthy Diet and Agroecology in General Pacheco, Argentina
Authors:   , Meave Anya Yvonne
Published: December 2023

This study explores the role Comunidad Milpa (Milpa) plays in implementing agroecology food systems in Comunidad Pacheco, Argentina. From teaching residents about food cultivation practices, to the importance of a healthy diet and developing relationship with local agroecology producers, the method builds upon the idea of food sovereignty and self-governance. Research conducted for this study focused on obstacles residents encountered while seeking to incorporate local agroecology foods into their diet. Incentives encouraging residents to support area agroecology efforts were also investigated, as well as barriers producers experienced while marketing their products. Design methods used for the investigation included both qualitative and quantitative methods in the form of surveys and interviews with members and participants of Milpa. Data gathered through both methods resulted in identifying the perspective Milpa participants have of the organization, their food practices and choices, and obstacles food producers encounter within the community.
Development of Biomimetic Human Lung Alveolus Chip
Authors:   , Man Kun
Published: December 2023

The potential of physiologically relevant in vitro cell culture models for studying physiological and pathophysiological phenomena has been widely recognized as replacements for animal and conventional in vitro models. To create models that accurately replicate the structure and function of tissues and organs, it is essential to comprehend the biophysical and mechanical features of the extracellular matrix (ECM) and incorporate them into the in vitro cell culture models. Therefore, we first aimed to investigate how nanotopography can modulate cell behaviors by studying cell behaviors on nanostructures of various aspect ratios on a cobalt-chromium-molybdenum (CoCrMo) alloy surface. We also explored the impact of nanofibrous membranes on the formation of alveolar epithelium, which is critical for lung alveolar interstitium chips. In addition, we investigated the effect of mechanical stretch on cell behaviors and focused on how the dimensionality of the stretch affects cell behaviors. To create physiologically relevant in vitro models based on our findings, we engineered a stem cell niche using a combination of nanofibrous membranes, mechanical stretch, and a soft substrate, and evaluated its impact on stem cell behaviors. Finally, we created a biomimetic human lung interstitium chip for application in physiological and pathophysiological in vitro studies.
Exploring Texas Music Educators' Health Literacy, Musician Health Literacy, and Intentions to Address the Health-Related Fine Arts TEKS in Ensemble Instruction Using the Newest Vital Sign, MHL-Q19, and Integrated Behavior Model
Authors:   , Taylor Meghan S.
Published: December 2023

This study assessed music educators' health literacy, musician health literacy, and intentions to teach the health-related Fine Arts TEKS in ensembles. An online survey was developed using the integrated behavior model, Newest Vital Sign (NVS), and Musician Health Literacy Questionnaire (MHL-Q19). Texas music educators who taught secondary band, choir, or orchestra were recruited via email and social media. Results: This survey yielded N = 207 respondents, with 43%, 29%, 14.5%, and 13.5% teaching band, choir, orchestra, and multiple ensembles, respectively. Most participants (67.6%) demonstrated adequate health literacy by answering at least four items correctly on the NVS. Attitude (p =.47) and personal agency (p =.30) were significant predictors of behavioral intention, while perceived norm was not (R2 =.484). Including NVS total score and MHL-Q19 total score in the model showed that while both factors improved the model (ΔR2=.038), only NVS total score was significant (p =.26) in predicting behavioral intention. Music educators in this study had adequate health literacy, which may contribute to their intentions to teach health concepts in ensembles. However, future efforts to improve these intentions should focus on bolstering perceived norms and personal agency by providing music educators with opportunities to take charge of implementing these concepts in their classrooms while showing that other stakeholders (i.e., campus administration, parents of students, and music educator colleagues) are also invested in presenting health concepts to student-musicians.
Self-Governance in a CPR Game: An Empirical Assessment of Elinor Ostrom's Eight Design Principles
Authors:   , Smith Alexandra Zachary
Published: December 2023

Nobel laureate and economist Elinor Ostrom earned a Nobel prize in economic sciences in 2009 for her research on a community's ability to self-govern a common pool resource with the use of eight design principles. While Ostrom's accumulated efforts to analyze these principles and apply them to community resources have earned widespread recognition, these principles have yet to take off on a grand scale as a blueprint for self-governance systems globally. There is also a lack of empirical evidence that supports these principles as empirical investigations have yet to manipulate the principles individually or as an intervention package as independent variables. The purpose of the present study is to empirically test Ostrom's eight design principles in a tabletop game model of a community utilizing a common pool resource (CPR) by implementing as well as removing the principles within an adapted version of the board game Catan. In three groups, the CPR almost always fully crashed in baseline but not when Ostrom's principles were in place as game rules. Results indicated that Ostrom's design principles may organize participant responses and maintain resource levels over time more effectively than without Ostrom's rules applied.
In-situ Electrochemical Surface Engineering in Additively Manufactured CoCrMo for Enhanced Biocompatibility
Authors:   , Mazumder Sangram
Published: December 2023

Laser-based additive manufacturing is inherently associated with extreme, unprecedented, and rapid thermokinetics which impact the microstructural evolution in a built component. Such a unique, near to non-equilibrium microstructure/phase evolution in laser additively manufactured metallic components impact their properties in engineering application. In light of this, the present work investigates the unique microstructural traits as a result of process induced spatial and temporal variation in thermokinetic parameters in laser directed energy deposited CoCrMo biomedical alloy. The influence of such a unique microstructural evolution in laser directed energy deposited CoCrMo on electrochemical response in physiological media was elucidated and compared with a conventionally manufactured, commercially available CoCrMo component. Furthermore, while investigation of the electrochemical response, such a microstructural evolution in laser directed energy deposited CoCrMo led to in-situ surface modification of the built components in physiological media via selective, non-uniform electrochemical etching. Such in-situ surface modification resulted in enhanced biocompatibility in terms of mammalian cell growth, cell-substrate adhesion, blood compatibility, and antibacterial properties indicating improved osteointegration, compared to a conventionally manufactured, commercially available CoCrMo component.
Positioning a Composer's Voice: Embodied Inquiry, Musical Analysis, and Educational Guides on Four Choral Works by Dr. Zanaida Stewart Robles
Authors:   , Stenson McKenna
Published: December 2023

In this dissertation, I study four choral works by Dr. Zanaida Stewart Robles through musical, thematic, and theoretical analysis to synthesize her compositional style. In addition to analysis, I created supplemental educational guides for each piece. These guides are intended to facilitate an intentional teaching process that leads to meaningful performances that engage the community. I investigate Robles' intersectional approach to composition as it reflects her identity as a Black, female composer. This project contextualizes Robles' voice and her impact on 21st-century choral music. I selected four works for study—"Umoja," "No Fairy Tale Here," "Can You See?" and "Psalm 61"— to represent three overarching themes in her oeuvre: spirituality, mental health awareness, and social justice. This research provides greater insight into Robles' choral works and serves as a thought-provoking introduction to commissioning works from underrepresented communities.
Examining the Links between Narcissism Domains and Self-Concept Clarity, Self-Esteem, Attachment, Emotion Regulation, and Aggression
Authors:   , Guillot Skyler Trace
Published: December 2023

Narcissism is currently being redefined as a multidimensional construct. While some researchers hold that narcissism remains a unidimensional phenomenon, others have suggested that bi- and tridimensional conceptualizations may better represent the construct as well as align more succinctly with the experiences of individuals with varying levels of narcissistic traits. Also, since the latter conceptualizations offer a broader assessment of narcissistic tendencies, they may provide greater accuracy in identifying differing narcissistic phenotypes (e.g., malignant vs vulnerable). Given the variety in conceptualizations of narcissism, it remains an open area as to how their respective domains are associated with various risk factors and behavioral outcomes, particularly within antagonistic forms of narcissism. This thesis explored the multidimensional approaches to defining narcissism and examined the associations between narcissistic traits and attachment style, self-concept, self-esteem, emotion regulation, and aggression. Also, the current study explored how differences in college degree (business vs. psychology) and gender may influence the expression of narcissism and associations with attachment style. Overall, the study provides results relevant for a tridimensional view of narcissism and adds to the literature on narcissism's link with factors involved in personality pathology, gender, and choice of college degree.
Annihilators of Irreducible Representations of the Lie Superalgebra of Contact Vector Fields on the Superline
Authors:   , Goode William M.
Published: December 2023

The superline has one even and one odd coordinate. We consider the Lie superalgebra of contact vector fields on the superline. Its tensor density modules are a one-parameter family of deformations of the natural action on the ring of polynomials on the superline. They are parameterized by a complex number, and they are irreducible when this parameter is not zero. In this dissertation, we describe the annihilating ideals of these representations in the universal enveloping algebra of this Lie superalgebra by providing their generators. We also describe the intersection of all such ideals: the annihilator of the direct sum of the tensor density modules. The annihilating ideal of an irreducible non-zero left module is called a primitive ideal, and the space of all such ideals in the universal enveloping algebra is its primitive spectrum. The primitive spectrum is endowed with the Jacobson topology, which induces a topology on the annihilators of the tensor density modules. We conclude our discussion with a description of the annihilators as a topological space.
Racial and Ethnic Differences in Trait vs Occasion Unipolar Depression
Authors:   , Gonzalez Zapata Deisy
Published: December 2023

Unipolar depression is a leading cause of disability and overall burden of disease for millions of individuals across the world. Depressive symptoms (e.g., depressed mood, anhedonia, fatigue, feelings of worthlessness, difficulties concentrating, etc.) can drastically affect an individual's life leading to occupational, social, and personal impairment. Past research shows significant ethnic and racial differences in depression rates and treatment. Moreover, previous literature has also begun to explore the multidimensional nature of depression, investigating its occasion-like (or episodic) and trait-like (or stable) factors. However, prior studies have not explored differences in occasion and trait depression by race or ethnicity, nor have they explored these questions in nurses, a group that faces substantial workplace stressors. To redress these gaps, the current study investigated trait and occasion depression in a large sample of nurses (N = 390) tracked across 12 months and aimed to understand whether trait versus occasion rates of depression differed by racial and ethnic minority status. Findings indicated substantially more trait depression (65.93%) than occasion depression (34.11%) across the year in nurses. However, there were no significant differences based on racial and ethnic minority status. Results highlight the importance of understanding depression as a much more stable aspect of an individual's personality, instead of merely viewing it as a direct response to changes in an individual's external environment. Additionally, findings suggest that focusing on adaptation of more long-term skills to target trait-like depression may be more helpful for nurses experiencing depression.
A Performance Guide for Five Mezzo-Soprano Arias from Chinese Operas
Authors:   , Xu Jingye
Published: December 2023

In the West, operas in Czech, English, French, German, Italian, Spanish, and Russian are the best known in collegiate and professional classical music settings. Given the changes in social climate in recent decades, however, attention is being given to the study and performance of under-represented minorities. There have been operas composed in the West on Asian topics, but one does not yet hear operas in Asian languages programmed as part of a regular season in major opera houses in the United States. The challenge for Western singers is threefold: access to the music, reading and pronouncing the language, and understanding the nuance of the rich Chinese culture in the libretto. This study presents the following five arias: "We Have to Be Apart," from The Dawns Here Are Quiet (这里的黎明静悄悄) by Tang Jianping; "The Daughter of Yimeng" and "Milk, Tears and Blood," from The Mountain of Yimeng (沂蒙山) by Luan Kai; "Forgetting Everything While Turning," from Saying Goodbye to Cambridge Again (再别康桥) by Zhou Xue Shi; and "Lullaby," from the opera The Orphan of Zhao (赵氏孤儿) by Lei Lei. It includes a brief biographical introduction to the composer and librettist for each opera, a synopsis of the plot, a description of the character singing the aria, transcriptions and romanizations of the text, IPA, word-by-word and poetic translations, translations of all musical directions in the score written only in Chinese, explanations of the cultural context, and vocal recommendations for performance. The purpose of the current dissertation is to study five arias for mezzo-soprano from Chinese operas with a view to making them accessible to Western singers.
The Ideal of Moral Cosmopolitanism and Human Rights in Edward Manukyan's "A World Without War"
Authors:   , Williams Krause Lyndi
Published: December 2023

The cantata A World Without War (2009), by Armenian-born composer Edward Manukyan (b. 1981), was written, in part, to support increased awareness of human rights issues. Based on a quote from linguist and philosopher Noam Chomsky (b. 1928), the narrative of the cantata states: "We can, for example, be fairly confident that either there will be a world without war or there won't be a world." In addition to Chomsky's words, the cantata excerpts quotes of two additional literary giants advocating human rights, Bertrand Russell (1872-1970), and Andrei Sakharov (1921-1989). The purpose of this dissertation is to focus attention on human rights activism; using Manukyan's A World Without War, I highlight moral and ethical questions at the center of this work and explain how this cantata embraces the ideal of moral cosmopolitanism. I strongly believe in the importance of human rights for all citizens of the world, and the role music plays in advancing its cause through performance arts.
Leadership Support for Teachers' Classroom Management and Student Behavior Professional Learning
Authors:   , Leonardo Melanie C.
Published: December 2023

Student behavior and classroom management are consistently identified as top reasons teachers leave the profession. A descriptive phenomenological study was conducted in a suburban school district in north Texas to identify how teachers perceive the deficits in their classroom management knowledge and to provide school leaders with data to guide plans for professional learning about effective classroom management strategies. Findings are based on both teachers' and principals' perceptions of supports that are needed or provided. Nine teachers (three elementary, three middle, and three high school) and six administrators (two elementary, two middle, and two high school) were interviewed using semi-structured interview protocols. Data were analyzed using seven a priori codes from which themes were developed. The findings showed that teachers generally do not feel well-prepared to address student behavior and classroom management. Emerged themes from both teacher and principal interviews identified deficits in professional learning received from their teacher preparation program, campus leaders, and district leaders. The top reasons why teachers struggled with student behavior and classroom management were: (a) application of learning, (b) deficits in support, (c) deficits in training, (d) physical and emotional toll, and (e) student deficits in social skill development. To help teachers feel better prepared to address student behavior and classroom management, they need: (a) to spend time with a first-and second-year teacher cohort, (b) be part of a campus with a growth mindset culture, (c) increased campus administrator support, (d) increased coaching support, (d) increased district administrator support, (e) revamped teacher preparation programs with relevant learning, and (f) differentiated, targeted professional learning.
Faulty Stimulus Control and Reduced Treatment Integrity: An Analysis of Position Biases
Authors:   , Nielsen Leif Erik
Published: December 2023

When learning conditional discriminations, it is possible that faulty sources of control develop and interfere with acquisition. In 2021, Bergmann et al. reported the effects of different integrity levels (i.e., to what degree an intervention is implemented correctly) on undergraduate students' mastery of an arbitrary matching to sample task. They found that participants in the reduced integrity conditions at or below 80% were more likely to show stimulus biases (i.e., selecting a particular incorrect stimulus in the presence of a sample stimulus) than participants in integrity conditions at or above 85%. Bergmann et al. did not investigate whether participants were likely to show responding that was biased by position. A position bias is a type of faulty stimulus control that involves allocating more responses to one or a few positions (e.g., first, second, middle, left). We conducted a secondary analysis of data from Bergmann et al., and we used a chi-square goodness of fit test to identify which participants showed a position bias. We found 25 participants out of 168 with potential position biases. We used a chi-square test of independence to analyze the distribution of participants with biased responding by condition and did not find a statistically significant difference. We discussed potential explanations for these findings and describe connections to behavior-analytic practice.
Modeling of Hypertrophic Cardiomyopathy Using hiPSC-Derived Cardiomyocytes with Static Mechanical Stretching
Authors:   , Rogozinski Nicholas
Published: December 2023

The heart is a dynamic environment that is constantly experiencing some degree of remodeling from the point of development, all the way through adulthood. While many genetic components may contribute to the overall presentation of hypertrophic cardiomyopathy (HCM), mutations occurring in sarcomere components such as myosin binding protein C3 (MYBPC3) are of the greatest popularity for study. Aiming to understand the mechanisms underlying heart diseases and to develop effective treatments that circumvent the need for direct patient study, we investigated the use of a platform to mimic the unique physiological conditions of HCM within an in-vitro setting. Following the induction of mechanical stretch on three human induced pluripotent stem cell derived cardiomyocyte (hiPSC-CM) cell lines containing mutations for MYBPC3 (WT, HET, HOM), all displayed HCM like reactions in calcium waveform. In conclusion, this system demonstrated the potential to apply a constant, static strain to healthy and mutated hiPSC-CMs for the MYBPC3 protein to model HCM in-vitro.
Chicana Decolonial Feminism: An Interconnectedness of Being
Authors:   , Gómez Maricruz Yvette
Published: December 2023

Chicana decolonial feminism asks us to re envision a world that allows for various forms of beings, creating identities based on political coalitions, having an active compassion that translates into direct action that seeks to dismantle binaries that reinscribe colonialism. Chicana decolonial feminist thought actively seeks to dismantle sexism, to dismantle racism, to focus on personal experience as theory, to focus on the body as knowledge, reconceptualize knowledge, envision new ways of being, and writing that is accessible to all. I use two concepts active compassion and interconnectedness of being that are central to chicana decolonial feminism. Chicana feminist texts and newspaper articles from the 1970s are analyzed to demonstrate how chicana decolonial feminism is seen in these texts.
An Evaluation of the Effects of Trauma-Related Stimuli on Behavior during Preference Assessments and Functional Analysis with People with Intellectual Disabilities
Authors:   , Houck Elizabeth Joy
Published: December 2023

People with intellectual disabilities (ID) face a high risk of experiencing adverse events including abuse, neglect, and serious medical issues. Access to effective interventions for people with moderate to severe ID is limited because of communication deficits that are characteristic of this population. Some of the negative effects of exposure to trauma for people with ID can include increases in problem behaviors. Behavior analysts have developed robust assessments and treatments to address these problem behaviors for people with ID; however, when these behaviors arise after a traumatic event, specialized assessments may be necessary to ensure effective treatment and decreased risk of re-traumatization. Specifically, if trauma-related stimuli (TRS) differentially affect preferences and functions of behavior, assessments of the effects of these stimuli may be critical to mitigate those effects. In my first experiment I found that TRS differentially affected behavior (including heartrate) during preferences assessments. In my second experiment I found that TRS differentially affected heartrate and the function of problem behavior for two of three participants. I discuss implications of these findings, including 1) that measuring some of the physiological effects of TRS using commercially available heart rate monitors could improve behavior analytic assessments for people with potential trauma histories; and 2) the presence of TRS can differentially affect the function of problem behavior in such a way that treatment plans developed and evaluated in either the presence or absence of TRS may be ineffective in the alternate setting.
Relevance Criteria when Searching and Evaluating Online Video for Informational Use
Authors:   , Dewitt-Miller Erin
Published: December 2023

Relevance is a core concept in the field of Information Science and a common term in everyday vernacular that generally refers to the usefulness of information. However, relevance has not been sufficiently or consistently defined or explored in the information science literature. Relevance criteria are the factors that information users employ when determining whether information they encounter is relevant. Identifying relevance criteria is a crucial step to understanding relevance. Relevance criteria employed with newer information formats like online video are especially important to study. Online video is now widespread, and people are increasingly likely to rely on video for information. This study identifies relevance criteria employed during relevance assessments of online video through a explanatory sequential mixed-methods study of frequent online video users including students, faculty, librarians, and video professionals. Methods included an online survey and interviews.
Onboarding Learning Modalities and the Relationships with Onboarding Experience, Locus of Control, Self-Efficacy, and Employee Engagement
Authors:   , Rieder Aubrey Taylor
Published: December 2023

Online and hybrid onboarding, or new-hire training and assimilation, has grown increasingly common in corporate settings, especially since the COVID-19 pandemic. This study explores how perceived onboarding experience, work locus of control, occupational self-efficacy, and employee engagement differed between those who onboarded with in-person, hybrid, or online methods. This study also explores how work locus of control could moderate these relationships and examines the relationships between employee engagement and onboarding experience, locus of control, and self-efficacy. This study used qualitative research methods in the form of a self-administered online questionnaire aimed at corporate employees who had onboarded within the previous 18 months. One hundred fifty-three employees completed the survey. It was found that no significant difference in the variables existed between modalities, except for the task characteristic subscale of perceived onboarding experience in which scores were lower for those onboarded in-person. However, work locus of control was found to significantly moderate the relationships between onboarding modality and experience, locus of control, and self-efficacy. Additionally, employee engagement was increased with higher perceived onboarding experience, more internal loci of control, and higher self-efficacy. In addition to the research questions, demographic data were also explored. It was found that perceived onboarding experience was negatively correlated with age, education level, and employment level, locus of control was negatively correlated with age, and work-related self-efficacy was positively correlated with employment level. Further, males were found to have more internal loci of control while females had more external loci of control. Women were also found to have statistically significant lower employee engagement. Overall, this study found that, while onboarding modality itself is not a predictor of employee experiences, other characteristics of onboarding and individuals' attributes could impact the success of onboarding programs and employees' experiences.
A Schenkerian Analysis and Interpretation of Joseph Jongen's Eclectic "Vingt-quatre petits préludes dans tous les tons pour piano," Op. 116 (1940-1941)
Authors:   , Liu Yi
Published: December 2023

Belgian composer Joseph Jongen (1873-1953) was an eclectic composer who successfully maintained his own unique musical vocabulary—particularly in his piano compositions. Jongen composed very little between 1940-1941—the period in which he and his family fled to the countryside of Mazères, France, living as refugees for several months before returning to Sart-lez-Spa, Belgium, due to the outbreak of WWII. Reflective of this time in his life, Vingt-quatre petits préludes dans tous les tons pour piano, op. 116 is composed in a particularly intimate and despairing way. Through a complete Schenkerian analysis and outline of the musical framework of op. 116—Jongen's last collection of piano pieces—this dissertation sheds light on the technique, imagination, and uniqueness of Jongen's WWII-period piano compositions. More specifically, this research outlines the deep-level tonal and formal structures, investigates the cryptic semantic meaning and intimate personal expression, and defines the aesthetic achievements of Jongen's Twenty-four Little Preludes in All Keys for Piano, op. 116.
Brazilian Adaptations of Baroque and Classical Elements in the Piano Sonata in F Minor, Op. 9, by Alberto Nepomuceno (1864–1920)
Authors:   , Wu Qifan
Published: December 2023

Alberto Nepomuceno was one of the leading figures in developing Brazilian art music at the turn of the twentieth century. He became widely known for his Brazilian art songs and kept promoting Brazilian music and the use of Portuguese as an "art language" throughout his life. Nepomuceno has widely been seen as a nationalist composer, yet some of his works adopt a more European style. In this study, I argue that Nepomuceno incorporates European musical languages in his Piano Sonata in F Minor, Op. 9. I display the rich interaction of Brazilian national identity and European influence within Nepomuceno's musical life. I also provide a thorough formal analysis of this piano sonata to argue that in some of his music he adopted a distinctively European musical language, including baroque and classical elements. In addition to analyzing the sonata-form and rondo-form elements, this dissertation discusses the use of several important topics in the work, including the Siciliano rhythm, contrapuntal writing, pedal points with organ effects, and impact of Brahms on Nepomuceno's piano writing. Moreover, I analyze how Nepomuceno assimilated European musical styles as the basis for his own compositions, as well as the innovations with which he augmented those styles. An analysis of this sonata can enhance our understandings of how musical training in Europe shaped the production of Latin American composers.
Diversity, Equity, and Inclusive Behaviors of School Librarians: Perceptions during Times of Crisis
Authors:   , Gill Diane
Published: December 2023

School librarians create an atmosphere where learners feel empowered. Moreover, school library programming should support diversity, equity, and inclusive learning opportunities to facilitate student success. Thus, school librarians are expected to model and advocate for equitable learning spaces while considering the universal design for learning approach to improving accessibility, utilization, and relevance for all library patrons. Although it has been established that school library standards support diversity, equity, and inclusion (DEI), more is needed to know about the impact of a crisis on school library programming and services. In addition, extensive research has not been conducted to determine school librarians' responsiveness and strategies to provide services for their school communities during disruptive times. This study examines school librarians' perceptions of the opportunities and challenges encountered while endeavoring to engage in DEI practices during crises.
Quantification of the Seasonality and Vertical Dispersion Environment of PM2.5 Variation: A Comparative Analysis of Micro-Scale Wind-Based Buffer Methods
Authors:   , Ray Noah R.
Published: December 2023

Increasing PM2.5 (particulate matter smaller than 2.5 micrometers) poses a significant health risk to people. Understanding variables critical to PM2.5 spatial and temporal variation is a first step towards protecting vulnerable populations from exposure. Previous studies investigate variables responsible for PM2.5 variation but have a limited temporal span. Moreover, although land-use classes are often taken into account, the vertical environment's influence (e.g., buildings, trees) on PM2.5 concentrations is often ignored and on-road circle buffers are used. To understand variables most critical to PM2.5 concentration variation, an air pollution sensor and GPS unit were affixed to a bicycle to sample for variables over three seasons (spring, summer, fall). Samples were taken on a route during the weekdays at four targeted hours (7AM, 11AM, 3PM, and 7PM) and joined with meteorological data. 3D morphology was assessed using LiDAR data and novel wind-based buffers. Wind speed only, wind direction only, and wind speed and direction buffers were computed and compared for their performance at capturing micro-scale urban morphological variables. Zonal statistics were used to compute morphological indicators under different wind assumptions in seasonal ordinary least squares regression models. A comprehensive wind and buffer performance analysis compares statistical significance for spatial and temporal variation of PM2.5. This study identifies the best wind parameters to use for wind-based buffer generation of urban morphology, which is expected to have implications for buffer design in future studies. Additionally, significant exposure hotspots for UNT students to PM2.5 pollution are identified.
