Examining the Links between Narcissism Domains and Self-Concept Clarity, Self-Esteem, Attachment, Emotion Regulation, and Aggression
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.

Expansion of Pianism through a Reinterpretation of Bartók's Dance Suite for Solo Piano (1925)
This project offers a comprehensive performance guide to Bartók's Dance Suite for solo piano based on a renewed interpretation of the piece. The Dance Suite (Táncszvit/Tanz Suite) is a unique work in Bartók's oeuvre, presented by the composer in two versions: one for orchestra (1923) and one for solo piano (1925). There has been little research done on this piece to enhance its popularity even though it may be a piece that illuminates one of Bartók's compositional philosophies: the unity of all cultures and folk song. Pianists must interpret this piece not only through the eyes of a soloist, but also as a musician who makes careful decisions—as if one were undertaking the making of a piano reduction of an orchestral score oneself. The methods presented intend to help pianists acquire and maintain a curious and flexible mind where freedom of interpretation is concerned, and hone inquisitive minds to overcome challenges when holding the reins of an orchestra across the eighty-eight keys of the piano towards limitless expansion and development of pianism and musicianship.

Experience Effects on Risk Perception and Protective Action Decision Making when Facing a Rare Tornado Threat
Damaging tornadoes are possible in all U.S. regions beyond the traditionally recognized "tornado alleys" in the southern plains and mid-south. Hence, this research examines how study participants respond to rare tornado events. Specifically, how disaster experiences affect risk perceptions and protective actions when facing a rare tornado event. This study used the protective action decision model (PADM) as the theoretical lens to investigate this issue. The PADM shows that personal characteristics, including personal disaster experience, could affect risk perceptions and how protective action decisions are made. This study applies the theory by recruiting 136 human subjects from the state of Washington to participate in a social experiment. The participants take part in a study that includes hypothetical tornado scenarios, ranging from thunderstorm warning to a tornado emergency then answering questions regarding the presented scenarios. Findings suggest that disaster experience and demographics influence how people perceive and respond to tornado disasters. Overall, people with direct and indirect tornado experiences showed significantly lower risk perceptions in the early stages of the threat when compared with those without any tornado experiences. Their tornado risk perceptions later increased when the threats were higher, and they tended to be more complacent regarding protective actions. This …

Exploring Asian American and Pacific Islander Youth Identity Development in a Community Based Youth Program
Community based youth programs play a significant role in promoting positive youth identity development outside of the classroom. This can be particularly important for racialized groups such as Asian Americans and Pacific Islanders (AAPI). Based on ethnographic research conducted at Asian American LEAD, this thesis explores the effect of a five week summer program on AAPI youth identity development. Data collection methods include participant observation, a pre- and post- survey, and semi-structured interviews with staff, participants, and program alumni. The research findings highlight how ethnic and racial identity development is fostered through the creation of safe spaces, shared struggles with peers and staff, and recognition of one's AAPI identity.

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
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 …

Exploring Undergraduate Nursing Students' Experiences with Interruptions: The Impact of Computer-Based Simulation on Their Knowledge and Satisfaction
The purpose of this study was to evaluate the impact of computer-based simulation on prelicensure senior second semester undergraduate baccalaureate nursing students' knowledge and satisfaction. The goal was to explore the current state of nursing education in relation to the nursing student's experience with interruptions and interruption management as interruptions and interruption management are an underexplored area of the nursing education experience, yet interruptions impact nursing performance and patient safety. Including effective interruption management in nursing education is the ultimate aim of this effort. The design of the study was a descriptive case study with mixed methods including quantitative and qualitative data collection and analysis. The quantitative analysis encompassed pretest and posttest drug calculation knowledge tests and a satisfaction survey. The qualitative portion of the study involved a focus group discussion relating to the nursing student's experience with interruptions and interruption management. The study results demonstrated that the participants were satisfied with the computer-based simulation. Furthermore, the results demonstrated that the professional nursing education of the study participants was devoid of interruption and interruption management education in the classroom, lab, and high-fidelity simulation. The themes that emerged from this study describe the current state of the second semester nursing student's …

Extending the Capabilities of Continuum Embeddings in First-Principle Simulations of Materials
In recent years, continuum models of solvation have had exceptional success in materials simulations as well as condensed matter physics. They can easily capture the effects of disordered systems, such as neutral liquids or electrolytes solutions, on material interfaces without the need for expensive statistical sampling. The Environ library (www.quantum-environ.org) implements different continuum models and correction schemes, which is the focus of this presentation. Recently refactored into a stand-alone library, many changes have been introduced in Environ, making it more flexible and computationally efficient. Introduction of a double-cell formalism allows for faster ab initio DFT calculations while reparameterization of soft-sphere continuum model allows for smaller density cutoffs. Furthermore, Environ's periodic boundary conditions correction schemes have been expanded by including the AFC90 library, which allows for faster DFT calculations of partially periodic systems, such as slabs, wires, and isolated molecules. Finally, stand-alone Environ can now provide atomic and molecular descriptors, which can be used to characterize solvated interfaces, e.g. in machine learning applications. The specific details of the implementations are reviewed as well as their efficiency and some choice applications for different calculation setups and systems.

Faulty Stimulus Control and Reduced Treatment Integrity: An Analysis of Position Biases
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. …

The First Lady of Washington City: Margaret Bayard Harrison Smith, Family, and Politics in the Early Republic
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 …

Greater, Lesser, Guessers: A Look into the Hybridization of Greater and Lesser Prairie-Chickens
My thesis focuses on the conservation consequences of the hybridization of Lesser Prairie-Chickens in Kansas. Specifically, examining how past land management practices altering the species ranges impact the distinctiveness of Lesser Prairie-Chickens. Each chapter is an individual publication that addresses if the Greater and Lesser Prairie-Chicken are distinct when applying the morphological and biological species concepts. Chapter 2 compares the evolutionary history and morphological construct of Lesser Prairie-Chickens and other Galliformes using morphometric analysis. Chapter 3 uses low-resolution microsatellite data to reflect recent changes at the population level. This study aims to observe the Greater and Lesser Prairie-Chicken using the morphological and biological species concepts, two of the many species concepts, to determine the distinctiveness and rate of hybridization for these closely related species.

Healing Miracles in Ancient Jewish and Early Christian Literature
Jesus was a healer, but what may not be as obvious is that he started a legacy of healing. He passed on his skills and abilities to his followers at least three times. Though not as frequently, they continued to heal through the Book of Acts. The legacy continued in the Apocryphal Acts and other apocryphal materials spanning the early centuries of the common era. Secondary literature looks at modern scholarship and leans heavily into Rabbinic literature. Up to this point, other English-language works in healing have sorely lacked luster in providing. The exploration of the healing legacy of Jesus shifted to meet the skills and needs of the healers, patients, and communities involved. Further, the healings had a substantive resultant impact on various levels of socioeconomics for the parties, which is explored by reexamining each group type of healings, from lameness and paralytics to possession and resurrection, and more. The hope is that taking a holistic approach to these healings as possible will allow readers a new way of experiencing the early common era and these events that permeated everyone's lives at one time or another.

"Her Terrible Splendor"
Her Terrible Splendor is a poetry collection that transports the Greek witch-goddess Circe from her mythical island of Aeaea to modern-day East Texas, where I was raised. By locating Circe in the Piney Woods, I heighten the strangeness that I identify with that setting and open up new contexts for considering Circe as a woman, as an enchanter, and as figure of retelling and revision. Circe appears in an array of roles—friend, lover, mentor, alter-ego, muse—as the poems view her through different lenses, including ekphrastic responses to visual art, rewritings of myths, and "portrait" poems that cast people from the human speaker's life as the goddess herself. A powerful mythic woman who works alone and creates a haven for strange creatures and lost humans, Circe offers a way for the manuscript to consider the complex, multifaceted process of coming of age as a woman, self-making as myth-making.

Hochschild Cohomology of Finite Cyclic Groups Acting on Polynomial Rings
The Hochschild cohomology of an associative algebra records information about the deformations of that algebra, and hence the first step toward understanding its deformations is an examination of the Hochschild cohomology. In this dissertation, we use techniques from homological algebra, invariant theory, and combinatorics to analyze the Hochschild cohomology of skew group algebras arising from finite cyclic groups acting on polynomial rings over fields of arbitrary characteristic. These algebras are the natural semidirect product of the group ring with the polynomial ring. Many families of algebras arise as deformations of skew group algebras, such as symplectic reflection algebras and rational Cherednik algebras. We give an explicit description of the Hochschild cohomology governing graded deformations of skew group algebras for cyclic groups acting on polynomial rings. For skew group algebras, a description of the Hochschild cohomology is known in the nonmodular setting (i.e., when the characteristic of the field and the order of the group are coprime). However, in the modular setting (i.e., when the characteristic of the field divides the order of the group), much less is known, as techniques commonly used in the nonmodular setting are not available.

How External Instructional Design Consultants Do Their Work: A Case Study
The purpose of this qualitative case study was to define and describe the work of external instructional design consultants. Study participants included seven instructional designers with varied educational backgrounds and work experience who work in a variety of contexts supporting clients in the design and delivery of learning experiences. All seven participants completed an initial survey with demographic and background questions. Five participants then took part in semi-structured interviews. Collected data was coded using both deductive and inductive methods with each case considered individually before combining the data for analysis across cases. Study findings support previous research suggesting that the work of instructional designers is dependent on context. Results further indicated that external instructional design consultants regularly engage in project management, communication and collaboration, and the analysis and evaluation components of the instructional design process, all in keeping with existing literature. External instructional designers differed in that they do more sales-related work, and, in the analysis process, focus more on client needs than learner characteristics. Study participants were invested in creating high quality, engaging learning experiences, while also willing to accommodate the unique challenges facing any given client. The study findings suggested that prospective employees' instructional design knowledge is of …

How Receiving Communities Structure Refugee Settlement Experiences: The Case of Burmese Immigrants in DFW
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 …

The Ideal of Moral Cosmopolitanism and Human Rights in Edward Manukyan's "A World Without War"
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.

"Idle Flux": A Composer/Choreographer Collaboration
The following thesis documents the collaboration process behind Idle Flux, a collaboration between Samuel A. Montgomery, a graduate composer at University of North Texas, and Emily Jensen, a graduate choreographer at Texas Woman's University. Comprising an 18-minute stereo fixed media composition and choreography for seven dancers, Idle Flux seeks to challenge the traditional spatial relationship between audience members and performers through restructuring seating and stage arrangements while featuring immersive sound design in multiple venues. This thesis considers multiple sources of inspiration, including Immersive Van Gogh® Exhibit Dallas, John Jasperse's Canyon, Zoe | Juniper's BeginAgain, Francisco López's installations, Alexander Ekman's A Swan Lake, Imagine Dragons' "Enemy," Son Lux's "Dream State (Dark Day)," and Ryan Lott's dance compositions. This thesis also examines the interdependent collaborative relationship between composer and choreographer by considering the issues of autonomy and creative control, examining previous collaborative models proposed or implemented by Van Stiefel, José Limón and Norman Lloyd, John Cage and Merce Cunningham, Doris Humphrey and Norman Lloyd. In addition, this thesis discusses the creative process and foundational concepts behind the fixed media composition, including the use of sound samples, exploration of timbre through synthesizers, development of motives and musical language, and the spatialization of sound …

The Impact of Culturally Relevant Pedagogy and Social and Emotional Learning Programs on Black Students
The study of culturally relevant pedagogy (CRP) within a social and emotional learning (SEL) program is timely as it supports the increasing body of literature on narrowing the educational gaps prevalent among Black students. Current research is lacking regarding if and how educators utilize CRP to support the learning of SEL competencies with Black students. For this study, the tenets of cultural relevance, SEL competencies, and the leadership practices of one urban district seeking to increase its overall accountability rating as deemed by the state of Texas were examined. The purpose of this study was to determine the adequacy of the district's response to the needs of Black students in terms of cultural relevance when selecting a SEL program and developing a support plan for the program's implementation at the campus level. A secondary purpose was to examine the extent to which the district embedded CRP practices into their adopted SEL program. A qualitative exploratory research design and case study research approach were utilized. Documents related to the SEL program chosen by the district were analyzed. In addition, semi-structured interviews with district leaders and a focus group with campus administrators were conducted. It was found that there were no direct …

The Impact of Invasive Salmonids on Ecosystem Functioning in South America's Sub-Antarctic Inland and Marine Waters
Invasions from coho salmon were first reported in the Cape Horn Biosphere Reserve (CHBR) in 2019 which is the most southern distribution registered to date. The CHBR is known for its high number of endemic species and unique biodiversity, such as the native fishes Galaxias maculatus and Aplochiton taeniatus. There are now three invasive salmonid species in the rivers of CHBR and are a potential threat to the native fish taxa. Stable isotope and gut content analysis were used to understand resource utilization by both native galaxiid and invasive salmonid taxa, as well as aquatic macroinvertebrates and riparian spiders. The natural laboratory study approach applied to this research, allowed for comparisons of differences within streams that contain conditions in which fish do not occur naturally, to sites in which high densities of invasive salmonid exist. Analysis of the trophic niche and diet in this study showed the importance of marine resource use by the native galaxiid and coho salmon juveniles supported with elevated δ15N and δ34S ratios. Diet analysis also confirmed there was the highest similarity between the coho salmon juveniles and the native fish. Altered behavior and habitat use was shown through the isotope and diet analysis for the …

The Impact of Reading Intervention on Student Achievement in Mathematics
With high stakes testing in public schools, pressure for success prompts schools to implement intervention programs for reading and mathematics, often at the expense of extra-curricular and elective activities. Previous literature indicated a correlation between reading comprehension and mathematical understanding. This study examined the specific intervention programs being utilized by two rural Texas school districts and the impact these programs had on student mathematic scores as measured by the State of Texas Assessment of Academic Readiness (STAAR). STAAR scores and student Response to Intervention (RtI) status were collected and identified over a five-year period for students Grades 3-7. Difference in scores for RtI and non-RtI and growth over time were examined using independent sample t-tests and one-way ANOVAs, respectively. Contrary to previous research, no significant impact was found on student math scores as a result of the reading enrichment programs utilized by the districts in the study. Results suggest current reading enrichment programs may not be the most effective for closing the achievement gap in mathematics and emphasized a need for further research to identify specific reading enrichment programs that could impact both reading and mathematics scores to increase both efficacy and efficiency of district intervention programs.

Implementing the Multicultural and Social Justice Counseling Competencies with Black, Indigenous, and Womxn of Color
The purpose of this descriptive multiple case study was to explore how counselors implement multicultural and social justice counseling competencies (MSJCC) when providing therapy to Black, Indigenous, and Womxn of Color. This study was informed by critical theory and intersectionality theory to capture the complex dynamics of identity and power through semi-structured interviewing, observations of archived counseling sessions, review of archived client case records, and administration of the Multicultural Awareness, Knowledge, and Skills Survey–Counselor Edition–Revised (MAKSS-CE-R), and the Social Justice Scale (SJS). The six doctoral student co-researchers provided rich portrayals of their experiences implementing the MSJCC, the role of identity, and the impact of power relations. Data revealed one overarching theme (the omnipresence of cultural humility), five themes (learning is a process, it starts with me: the catalyst of self-awareness, this is my identity, understanding clients in context: attending to power and intersectionality, and social justice is awareness: advocacy is intentional and active), and eight corresponding subthemes. Co-researchers provided insight into their experiences of barriers, oppression, resilience, and advocacy. Implications and conclusions from this research provide recommendations for mental health counselors, education programs, and research.

In-situ Electrochemical Surface Engineering in Additively Manufactured CoCrMo for Enhanced Biocompatibility
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.

Industry Challenges for an Under-Skilled Workforce
This study examined the challenges companies encounter attempting to fill job vacancies with applicants having the requisite skills. Of the 115 journals evaluated as part of the literature review, 64% of the documents identified issues related to workplace skills development deficiencies in industry and academia. Additional findings related to vocational training programs, training for youth, training content issues, and investments in skills training are evaluated. The literature review suggests both industry and academia struggle with developing and training students and the workforce with the new technology skills demanded in today's workplace. A research study, conducted in an industrial manufacturing company, was performed based on two data sets (defect quantities and repair hours). Each of the data sets consisted of production performance data collected during three time periods (pre-treatment, proximal treatment, and distal post-treatment). The Treatment consisted of the development of a training course focused on the assembly and installation of electrical harness assemblies into electronic equipment cabinets. Specific industrial assembly requirements and process outcomes were addressed in the curriculum design. The statistical analysis of the quantitative data indicated there was a statistically significant outcome associated with the proximal treatment of the repair hours data set. However, the applied treatment did …
