An Introduction to Contemporary Violin Techniques: A Practical Guide with Exercises for Students and Teachers
Authors:   , Detwiler Mia
Published: January 2025

Violin repertoire composed in the late twentieth and early twenty-first centuries placed new demands on performers. While numerous pedagogues have written etudes and treatises analyzing traditional techniques, far fewer have thoroughly examined contemporary techniques. Many of the existing etudes and exercises inspired by contemporary violin repertoire are of a very high difficulty level and may seem unapproachable to students with little to no experience performing the music of recent decades. As a result, many violin students are unacquainted with the language of new music. This dissertation is intended to help fill a gap in the pedagogical literature by serving as a resource that familiarizes advanced students with the notation and proper execution of the non-traditional techniques commonly found in contemporary violin music. This document includes a survey of violin repertoire written since 1970, an analysis of the non-traditional techniques used most often in the works examined, methods for approaching specific technical problems that arise in them, and nine etudes originally composed by this author. The etudes focus on nine contemporary techniques, ranging from contact point variations to changing subdivisions, and are intended for study by advanced violinists interested in performing contemporary music.
Multi-Omics Based Investigation of Distinct Early Oxidative Stress Responses of Saccharomyces cerevisiae to Various Oxidants
Authors:   , Pandey Prajita
Published: January 2025

The early signaling mechanism(s) that control oxidant perception and signal transduction leading to activation of the antioxidant defense response and survival mechanisms tailored toward specific oxidative insult remains unknown. Here, we identified early changes in metabolome and proteome of S. cerevisiae in response to hydrogen peroxide, menadione, cumene hydroperoxide, and diamide. Firstly, global untargeted LC–MS/MS analysis allowed us to identify 196 proteins in response to hydrogen peroxide, 569 proteins in response to cumene hydroperoxide, 369 proteins in response to menadione and 207 proteins in response to diamide that were significantly regulated at 3 min after exposure. We revealed that each oxidant triggered unique signaling mechanisms associated with survival and repair mechanisms as early as 3 minutes of post treatment with a set of proteins that uniquely responded to the particular oxidant. In addition, our comprehensive pathway analysis revealed signaling pathways and the molecular players that are regulated globally by all oxidants at early time points namely Ran, mTOR, Rho, and eIF2. Additionally, we analyzed metabolic response using targeted GC-MS/MS that allowed us to identity 35 metabolites that were consistently detected in all samples at 3 min of exposure. These metabolites showed distinct response to the four oxidants in carbohydrate metabolism, tricarboxylic acid, amino acid metabolism and glutathione cycle. Furthermore, temporal analysis showed targeted metabolites significantly regulated at different time points by different oxidants suggesting specificity in the response to oxidants having different mode of actions.

Gabriel Pierné's Sonata in D Minor, op. 36: A Study of the Work's Compositional Language and Context, Focusing on the Composer's Transcription for Flute
Authors:   , Le Huong Thu
Published: January 2025

There are very few significant sonatas for flute and piano written between 1880 and 1918, a period of unusually rich stylistic diversity. Gabriel Pierné composed his Sonata in D Minor, Op. 36 for piano and violin in 1900, and later transcribed it for flute and piano. Unfortunately, the work has not been embraced to a significant extent by either violinists or flutists. The wealth of violin sonatas from this period might explain it not becoming part of the canon for violinists, but this is not the case for the flute repertoire, where it seems that it should hold a place of genuine importance. Since little has been written about Pierné as a composer or about this piece in either of its versions, this project is intended to promote an understanding of the work in its historical and theoretical context and to advocate for more frequent performances. This document also suggests an alternate version of several particular passages so it can better represent the characteristics of today's flute and its modern techniques. This research will help other flutists and flute professors to introduce and spread an awareness of its existence and ideally helping to establish its place in the flute repertoire. From a historical standpoint, this dissertation also offers a case study of Gabriel Pierné's place, both stylistically and institutionally, in the history of French music in fin-de-siècle. Both of these goals fill important gaps in the existing research literature.
François Couperin's Neuvième Concert, "Ritratto Dell' Amore": A Performance Guide and Edition for Flute and Keyboard
Authors:   , Wong Ieng Wai
Published: January 2025

François Couperin (1668-1733) was one of the earliest French Baroque composers to merge the Italian style into the French tradition. He had great influence on the development of French Baroque music from the end of the seventeenth century until his death. Couperin's four Concerts Royaux and the ten Concerts Nouveaux (published in 1722 and 1724) were written for the enjoyment of Louis XIV. Those suites were popular in the court before they were published, as they were requested to be performed every Sunday during the years 1714 and 1715 to give pleasure to the king. Rittrato dell'amore is the ninth suite out of the fourteen suites. The purpose of this study is to provide a performance guide and a practical edition of François Couperin's Neuvième Concert Ritratto dell' amore. It also contrasts Italian style and French tradition in the Baroque period, and how Couperin blended both styles together in his Neuvième Concert. In addition, this dissertation summarizes the general principles of Baroque performance practice that one may encounter in Neuviéme Concert, including notes inégales (unequal notes), ornamentation, over-dotting, and other issues. It is especially important for one to understand the performance style of French Baroque music in order to perform these works appropriately, since its notation did not adequately notate rhythmic expectations as traditionally understood and the realization of ornamentations in this period and style is highly specific. The tradition was indeed lost in terms of aural transfer and has been reconstructed through published scholarly work in the last century that is based on treatises of the time. Ongoing scholarly and artistic work should bring us ever closer to the ideals of the period.
Ethnic-Racial Socialization, Ethnic-Racial Identity, and Psychosocial Functioning
Authors:   , Hasan Faraha
Published: January 2025

The current research recruited 200 college students from the University of North Texas to explore the direct and indirect effects of familial ethnic-racial socialization on selected psychosocial variables (i.e., general self-efficacy, life satisfaction, and psychological distress) via ethnic-racial identity variables: exploration, affirmation, and resolution. The results indicated that cultural socialization from family predicted life satisfaction via exploration and resolution, predicted general self-efficacy via affirmation and resolution, and predicted psychological distress via affirmation. Additionally, patterns between exploration, affirmation, and resolution were explored through cluster analyses, and six ethnic-racial identity clusters were identified. The amount of familial ethnic-socialization and general self-efficacy reported by participants varied significantly among the identified ethnic-racial identity clusters. Implications of the findings for therapeutic interventions, university programs, and ethnic-racial identity measurement as well as limitations and future research directions are discussed.
Change, Longing, and Frustration in Djent-Style Progressive Metal
Authors:   , Sallings Patrick Nolan
Published: January 2025

The progressive metal style "djent" emerged in the mid-to-late 2000s with bands that modeled their use of extended range instruments and complex rhythmic cycles after that of Swedish metal band Meshuggah. The addition of a new vocabulary of melody and harmony by bands such as Periphery, Tesseract, and Animals as Leaders has come to define djent in a new way and provided fruitful ground for voice-leading and metrical analysis. In this dissertation, I approach analysis in two steps. The first step is the production of detailed transcriptions of four djent songs. The process of transcription has allowed for the development of Transcription Preference Rules, modeled after Lerdahl and Jackendoff's preference rule approach in their Generative Theory of Tonal Music. The Transcription Preference Rules account for the selection of key signatures, time signatures, and other features of the scores that may affect analysis. Second, using these scores, I examine the connection between the textual topic of change and the voice-leading and metrical structures in Periphery's "Insomnia" and Tesseract's "Of Matter." I show how this topic is reflected by techniques such as change melodic direction, multidimensional metrical dissonance, and auxiliary cadential events. Finally, I apply voice-leading and metrical analysis to Animals as Leaders's "Tempting Time" and Mute the Saint's "Sound of Scars" in order to show what these analytical techniques reveal about instrumental djent pieces. I show how shifts in meter in "Tempting Time" can be represented cyclically. I conclude by showing how the interaction of metal and North Indian Classical techniques produces a unique representation of Mute the Saint's topic of longing and frustration in "Sound of Scars."
Viability Study of Nylon-12 Carbon Fiber Filaments for Use in the Construction of a Powered Lower Body Exoskeleton via Fused Deposition Modeling by Means of Computer Simulation
Authors:   , Joiner Michael Andrew Lown
Published: January 2025

Members of the elderly population is disproportionately prone to experiencing mobility impairment due to their aging bodies and as a result have frail bodies that are at a higher risk of grave injury due to falling. In order to combat this assistive mobility devices such as exoskeletons have been developed to help patients enhance their range of motion. With additive manufacturing techniques, such as fused deposition modeling (FDM), becoming a more mainstream form of design, the inclusion of lightweight polymers such as nylon 12 as primary construction materials for these devices has increased. In this thesis computer aided design (CAD) software was used to design a prototype lower body exoskeleton and simulation software was used to give the device the characteristics of Stratasys' nylon 12 carbon fiber FDM material to verify it if could be used as the primary construction material for this device when extruded from a FDM printer on either the XZ or ZX printing plane. From the simulations it was found that the material printed along the XZ plane could create a device that could withstand the weight of an average elderly male patient (200 lbs.) as well as the 35 lbs. of force applied to the device by a linear actuation motor that would be used to extend and contract the exoskeleton leg.
Locke and Penal Labor
Authors:   , McGuffee Alaina Grace
Published: January 2025

Interest and concern about penitential labor practices has been growing among scholars recently. The relationship of these practices to the principles of American liberalism, and in particular its Lockean roots, have not been thoroughly studied. The present investigation traces contemporary practices to features of Lockean liberalism, and offers suggestions for how to respond to widely acknowledged deficiencies while remaining within the broadly accepted principles laid out by Locke. The advantages of such an approach include political stability.
Probabilistic Modeling for Whole Metagenome Profiling
Authors:   , Burks David
Published: January 2025

To address the shortcomings in existing Markov model implementations in handling large amount of metagenomic data with comparable or better accuracy in classification, we developed a new algorithm based on pseudo-count supplemented standard Markov model (SMM), which leverages the power of higher order models to more robustly classify reads at different taxonomic levels. Assessment on simulated metagenomic datasets demonstrated that overall SMM was more accurate in classifying reads to their respective taxa at all ranks compared to the interpolated methods. Higher order SMMs (9th order or greater) also outperformed BLAST alignments in assigning taxonomic labels to metagenomic reads at different taxonomic ranks (genus and higher) on tests that masked the read originating species (genome models) in the database. Similar results were obtained by masking at other taxonomic ranks in order to simulate the plausible scenarios of non-representation of the source of a read at different taxonomic levels in the genome database. The performance gap became more pronounced with higher taxonomic levels. To eliminate contaminations in datasets and to further improve our alignment-free approach, we developed a new framework based on a genome segmentation and clustering algorithm. This framework allowed removal of adapter sequences and contaminant DNA, as well as generation of clusters of similar segments, which were then used to sample representative read fragments to constitute training datasets. The parameters of a logistic regression model were learnt from these training datasets using a Bayesian optimization procedure. This allowed us to establish thresholds for classifying metagenomic reads by SMM. This led to the development of a Python-based frontend that combines our SMM algorithm with the logistic regression optimization, named POSMM (Python Optimized Standard Markov Model). POSMM provides a much-needed alternative to metagenome profiling programs. Our algorithm that builds the genome models on the fly, and thus obviates the need to build a database, complements alignment-based classification and can thus be used in concert with alignment-based classifiers to raise the bar in metagenome profiling.
Activating Artistry: Community Engagement Resources and Teaching Artist Strategies for the Bassoonist
Authors:   , Spring Staci
Published: January 2025

This document examines current practices and opportunities in the music performance field related to artistic citizenship, community engagement, and the field of teaching artistry. The relationship of musicians to their audiences and communities has shifted significantly in the twenty-first century, and there is an increasing need to redefine the essential skills of the professional musician. Derived from the field of teaching artistry, the concept of "activating artistry" suggests that our greatest strength and power as artists lies in drawing out individual artistic expression in other people, and it is with this power that artists as a workforce can create meaningful change in society. This intention could be manifested in many different contexts during the course of a given music career, however, developing the tool kit necessary for engaging in such work is not widely emphasized in the training of musicians. What tools can be provided for students and professionals to help them navigate both traditional and evolving career paths in music? How are bassoonists doing as a field in addressing the imperative of community engagement and artistic citizenship? How might we explore more collaborative ways to engage with our diverse communities – ways that value their perspectives? These questions guide an exploration of current practices in the bassoon field, with an overall goal of providing practical examples, resources, and inspiration for engaging in the work of activating artistry. Central to the discussion is the intersection of the professional bassoonist with the teaching artist field. Examples of lesson plans/strategies and ideas for curating educational performances demonstrate potential uses of the bassoon and its repertoire in teaching artist residencies and other community engagement settings.
Structural Analysis and Finite Element Modeling of Aluminum Honeycomb Sandwich Structures
Authors:   , Doukoure Maimouna
Published: January 2025

The objective of this research is to determine how the sandwich's physical characteristics have an impact on the mechanical properties, determine under what conditions the specimens will be lighter and mechanically stronger, and determine if the use of an aluminum honeycomb sandwich as a construction material is feasible. The research has aimed at the use of aluminum sandwiches as light and strong material. The study of the structural layers' damage resistance and tolerance demonstrated that the top and bottom layers play a crucial role. The thesis presents three test results from aluminum honeycomb sandwich compression horizontal, compressive vertical, and bending tests. Also, each group was displayed mechanically and simulated in Abaqus. The study determines the mechanical properties such as maximum elastic stress-strain, ultimate stress-strain, fracture point, density, poison ration, young modulus, and maximum deflection was determined. The energy absorbed by the FEA, such modulus of elasticity, resilience, and toughness, the crack propagation, the test's view shows aluminum honeycomb behaved like a brittle material with both compression test. And the maximum deflection, crack propagation, shear forces, bending moment, and images illustrated that the layers play a crucial role in the 3-point bend test.
Adult Attachment Anxiety and Relationship Satisfaction: The Role of Dedication and Constraint Commitment
Authors:   , Chao Wan Ju
Published: January 2025

Adult attachment has been found to play an important role for romantic relationship satisfaction. Specifically, the existent literature generally suggests that attachment anxiety is negatively related to relationship satisfaction. However, the underlying mechanism for this link still needs further exploration. The present study examined the direct and indirect effect of attachment anxiety on relationship satisfaction via two distinct relationship commitment variables: constraint commitment and dedication commitment. The final sample included 146 unmarried participants who were in a romantic relationship for at least three months. Results of multiple regression analyses on the indirect effect model indicated that attachment anxiety had a significant direct effect on relationship satisfaction as well as a significant indirect effect on relationship satisfaction via constraint commitment. However, the hypothesized indirect effect through dedication commitment was not supported. Findings are discussed from the adult attachment perspective. Counseling implications, limitations, and future research directions are outlined.
An Introduction to the Piano Works of William Mason (1829-1908) and a Performance Guide to Selected Repertoire for Intermediate Students
Authors:   , Chen Ying-Chieh
Published: January 2025

William Mason (1829–1908) was a well-known American composer, pianist, and pedagogue. Researchers have mainly focused on Mason's career as a pedagogue in the United States and his pedagogical treatises, which are widely considered and used as the conceptual core of teaching materials on the nineteenth century. However, there has been only an annotated catalogue of Mason's music works, and no performance guide to his piano compositions. This dissertation is designed to be the first performance guide to his solo piano repertoire and act as an introduction to his music through an examination of selected works suitable for the intermediate student. This study provides instruction for students on how to practice these works through the analysis of the elements of practice – pedaling, phrasing, technique practice, touch, and musical expression – which were all considered as essential by Mason himself for a good performance. The five piano works selected are: Three Preludes, Op. 8, No. 1; Ballade et Barcarole, Op. 15; Valse Caprice, Op.17; Spring-Dawn, Mazurka–Caprice, Op. 20; and Spring Flower–Impromptu, Op. 21.
The Impact of a Long Term, 5E Inquiry-Based Professional Development on Content and Pedagogical Knowledge in Eighth-Grade Science Teachers
Authors:   , Waid Julie
Published: January 2025

The purpose of this mixed-methods study was to examine the impact of a long-term, 5E inquiry-based professional development on content and pedagogical knowledge in eighth-grade science teachers in Texas. Qualitative and quantitative data were collected via university designed reflective prompts, science content pretests and post-tests, and a classroom observation instrument. Results showed the professional development had a statistically significant impact on teachers' content knowledge in earth science, less significant impact in content knowledge in physical science and that teachers' levels of inquiry-based practice were in the early stages. The teachers' reflections of the professional development's impact indicated self-identified growth in their content knowledge and an impact on their understanding of inquiry-based classroom instructional practice. The findings suggest inquiry-based professional development has an impact on teachers' content and pedagogical knowledge, specifically regarding conveying content effectively, concept interconnection, lesson design, and teachers' opportunities to experience inquiry-based learning themselves before implementing it in their classrooms. The study's implications for further research include examinations of professional learning opportunities at local district and campus levels to identify and incorporate science teachers' existing levels of content and inquiry-based pedagogical knowledge and provide opportunities for practice to incorporate the pedagogy in classrooms.
A Novel Thermal Regenerative Electrochemical System for Energy Recovery from Waste Heat
Authors:   , Gray David B
Published: January 2025

Waste-heat-to-power (WHP) recovers electrical power from exhaust heat emitted by industrial and commercial facilities. Waste heat is available in enormous quantities. The U.S. Department of Energy estimates 5-13 quadrillion BTUs/yr with a technical potential of 14.6 GW are available and could be utilized to generate power by converting the heat into electricity. The research proposed here will define a system that can economically recover energy from waste heat through a thermal regenerative electrochemical system. The primary motivation came from a patent and the research sponsored by the National Renewable Energy Laboratory (NREL). The proposed system improves on this patent in four major ways: by using air/oxygen, rather than hydrogen; by eliminating the cross diffusion of counter ions and using a dual membrane cell design; and by using high concentrations of electrolytes that have boiling points below water. Therefore, this system also works at difficult-to-recover low temperatures. Electrochemical power is estimated at 0.2W/cm2, and for a 4.2 M solution at 1 L/s, the power of a 100 kW system is 425 kW. Distillation energy costs are simulated and found to be 504 kJ/s for a 1 kg/s feed stream. The conversion efficiency is then calculated at 84%. The Carnot efficiency for a conservative 50% conversion efficiency is compared to the ideal Carnot efficiency. Preliminary work suggests an LCOE of 0.6¢/kWh. Industrial energy efficiency could be boosted by up to 10%. Potential markets include power stations, industrial plants, facilities at institutions like universities, geothermal conversion plants, and even thermal energy storage.
Factors that Affect HIPAA Compliance: A Bibliometrics Study
Authors:   , Drayden Craig M.
Published: January 2025

According to the U.S. Department of Health and Human Services (HHS), patients and providers do not understand the Health Information Privacy and Accountability Act (HIPAA). Non-compliance with HIPAA is primarily due to confusion, along with insufficient understanding. HSS has taken measures to simplify the language they use to communicate HIPAA, however, they have not taken steps that consider if one's culture, religious and social perspectives, institutional training, credentials, and comprehension of legal terminology affects medical providers and non-clinical administrative personnel's abilities to understand HIPAA. This research uses bibliometrics to examine the literature from January 2010 – September 2020 that addresses HIPAA's use of legal terminology, literacy level, and institutional training, along with religious and social perspectives, and credentials of medical providers and non-clinical administrative personnel. A total of 107 articles were examined, 42 were assigned article influence scores with values that were less than 1.00, which is a below-average influence score for the article. There were 29 articles with values equal to or above 1.00, which translates to an equal or above-average influence score. The remaining 36 articles did not have article influence scores and were assigned values as not available. Results of the review of the literature indicate that legal terminology, literacy level, training, credentialing and religious and social perspective had no or little effect in understanding HIPAA.

Investigation of Porous Ceramic Structure by Freeze-Casting
Authors:   , Bakkar Said Adnan
Published: January 2025

The design and fabrication of porous ceramic materials with anisotropic properties has, in recent years, gained popularity due to their potential application in various areas that include medical, energy, defense, space, and aerospace. Freeze-casting is an effective, low-cost, and safe method as a wet shaping technique to create these structures. To control the morphology of these materials, many critical factors were found to play an important role. In this dissertation, the processing parameters of the magnetic field-assisted freeze-casting method were optimized with a focus on comparing the structure obtained using vertical and horizontal magnetic fields and understanding the mechanisms that occur under different freezing modes. More specifically, this processing method was used to produce Al2O3 and B4C porous ceramics materials with unidirectionally-aligned pore channels. The effect of the vertical and horizontal magnetic field strength and direction, concentration of magnetic material (Fe3O4), cooling rate, and freezing time were examined. The resulting ceramics with highly aligned pore channels were infiltrated with molten metal to create metal matrix composites. The mechanical properties of these structures were measured and were subsequently correlated to their morphology and composition.
Development and Exploration of End-User Healthcare Technology Acceptance Models
Authors:   , Wei Xinyu "Eddy"
Published: January 2025

This dissertation consists of three studies that collectively investigate the factors influencing the consumer adoption intention towards emerging healthcare technologies. Essay 1 systematically reviews the extent literature on healthcare technology adoption and serves as the theoretical foundation of the dissertation. It investigates different models that have been previously applied to study healthcare technology acceptance. Meta-analysis method is used to quantitatively synthesize the findings from prior empirical studies. Essay 2 posits, develops, and tests a comprehensive biotechnology acceptance model from the end-user's perspective. Two new constructs, namely, perceived risk and trust in technology, are integrated into the unified theory of acceptance and use of technology. Research hypotheses are tested using survey data and partial least square – structural equation modeling (PLS-SEM). Essay 3 extends the findings from the Essay 2 and further investigates the consumer's trust initiation and its effect on behavioral adoption intention. To achieve this purpose, Essay 3 posits and develops a trust model. Survey data allows testing the model using PLS-SEM. The models developed in this dissertation reflect significant modifications specific to the healthcare context. The findings provide value for academia, practitioners, and policymakers.
Alloy Design, Processing and Deformation Behavior of Metastable High Entropy Alloys
Authors:   , Frank Michael
Published: January 2025

This dissertation presents an assortment of research aimed at understanding the composition-dependence of deformation behavior and the response to thermomechanical processing, to enable efficient design and processing of low stacking fault energy (SFE) high entropy alloy (HEAs). The deformation behavior and SFE of four low SFE HEAs were predicted and experimentally verified using electron microscopy and in-situ neutron diffraction. A new approach of employing a minimization function to refine and improve the accuracy of a semi-empirically derived expression relating composition with SFE is demonstrated. Ultimately, by employing the minimization function, the average difference between experimental and predicted SFE was found to be 2.64 mJ m-2. Benchmarking with currently available approaches suggests that integrating minimization functions can substantially improve prediction accuracy and promote efficient HEA design with expansion of databases. Additionally, in-situ neutron diffraction was used to present the first in-situ measurement of the interspacing between stacking faults (SFs) which were correlated with work hardening behavior. Electron transparent specimens (< ~100 nm thick) were used in order to resolve nanoscale planar faults instead of the thicker sub-sized specimens (on the order of millimeters in thickness) which exhibit the classical stages III work hardening behavior characteristic of low SFE metals and alloys. The present study demonstrates these characteristic dimensions of SFs can be tracked in real-time using neutrons or high-energy x-rays. SFs have also been shown to act as barriers to dislocation motion and thus contribute to strengthening and sustained work hardening during deformation.

Modeling, Characterization, and Magnetic Behavior of Transition Metal Nanosystems Synthesized in Silicon Using Low Energy Ion Implantation
Authors:   , Singh Satyabrata
Published: January 2025

Magnetic nano-clusters in silicon involving iron and cobalt were synthesized using low energy (50 keV) ion implantation technique and post-implantation thermal annealing. Before the irradiation, multiple ion-solid interaction simulations were carried out to estimate optimal ion energy and fluence for each experiment. For high-fluence low-energy irradiation of heavy ions in a relatively lighter substrate, modeling the ion irradiation process using dynamic code SDTrimSP showed better agreement with the experimental results compared to the widely used static simulation code TRIM. A saturation in concentration (~ 48%) profile of the 50 keV Fe or Co implants in Si was seen at a fluence of ~ 2 × 1017 ions/cm2. Further study showed that for structures with a curved surface, particularly for nanowires, better simulation results could be extracted using a code "Iradina" as the curve geometry of the target surface can be directly defined in the input file. The compositional, structural, and magnetic properties were studied using Rutherford backscattering spectrometry, X-ray photoelectron spectroscopy, X-ray diffraction, atom probe tomography, and vibrating sample magnetometry. Irradiation of high-current (~ 2 μA/cm2) 50 keV Fe ions into Si at a fluence of 2 × 1017 ions/cm2 showed the formation of Fe5Si3 nano structures in the near-surface region of the substrate. Post-implantation thermal annealing in vacuum at 500 οC for one hour showed a significant enhancement in structural and magnetic properties. Similar high-current irradiation of 50 keV Co with a fluence of 3.2 × 1016 ions/cm2 into Si substrate showed the formation of superparamagnetic structure even at room temperature in the as-implanted samples. The simulation results for irradiation of Co and Fe on the curved surface were validated by ion irradiation on pre-fabricated Si nano tip followed by atom probe tomography analysis.
Collaboration among Conflict Management Practitioners and Human Rights Advocacy Groups
Authors:   , Akyol Seyma N.
Published: January 2025

In a civil war, conflict management practitioners are concerned with bringing the conflict to an end and providing security for civilians. Similarly, human rights advocacy groups are also concerned with minimizing civilian harm. Given the similar intentions of these actors in civil war states, this dissertation explores under what circumstances conflict management practitioners and human rights advocacy groups collaborate. First, I compare to what extent mediation and peacekeeping cases differ with regards to showing signs of interaction; second, I compare how the level of interaction changes depending on whether peacekeeping missions are deployed by the United Nations or regional intergovernmental organizations. I find that human rights groups are more likely to interact with peacekeeping missions, especially when the missions are deployed by the United Nations. Moreover, I analyze to what extent the interaction between human rights groups and peacekeeping operations impacts how human rights groups carry out their advocacy efforts. The findings reveal that the way human rights groups use their advocacy efforts depend on whether the third parties providing peacekeeping operations respond to their requests.
Social Media Usage among First Responders to Hurricane Harvey
Authors:   , Spinuzzi Lacey Cook
Published: January 2025

Social media plays an important role during multiple phases of a disaster. While it is widely known that citizens turn to social media during disasters to gain information and send help requests, there is a significant gap in our knowledge of how, or if, first responders use social media to conduct disaster response operations. To help address this gap this study employed qualitative, semi-structured interviews with a sample of first responders (N = 20) who were deployed to Hurricane Harvey in 2017. The interviews sought to gain a better understanding of how social media was used to conduct response operations and identify both limitations and advantages of social media as perceived by first responders. Through a systematic coding process the analysis identified four themes related to social media usage among first responders to disasters: (1) more than just Twitter; (2) rumor has it; (3) one size does not fit all; and (4) timing is everything. The findings of this research highlight the importance of social media for both organizations and individuals involved in responding to disasters.
Hybrid Optimization Models for Depot Location-Allocation and Real-Time Routing of Emergency Deliveries
Authors:   , Akwafuo Sampson E
Published: January 2025

Prompt and efficient intervention is vital in reducing casualty figures during epidemic outbreaks, disasters, sudden civil strife or terrorism attacks. This can only be achieved if there is a fit-for-purpose and location-specific emergency response plan in place, incorporating geographical, time and vehicular capacity constraints. In this research, a comprehensive emergency response model for situations of uncertainties (in locations' demand and available resources), typically obtainable in low-resource countries, is designed. It involves the development of algorithms for optimizing pre-and post-disaster activities. The studies result in the development of four models: (1) an adaptation of a machine learning clustering algorithm, for pre-positioning depots and emergency operation centers, which optimizes the placement of these depots, such that the largest geographical location is covered, and the maximum number of individuals reached, with minimal facility cost; (2) an optimization algorithm for routing relief distribution, using heterogenous fleets of vehicle, with considerations for uncertainties in humanitarian supplies; (3) a genetic algorithm-based route improvement model; and (4) a model for integrating possible new locations into the routing network, in real-time, using emergency severity ranking, with a high priority on the most-vulnerable population. The clustering approach to solving dept location-allocation problem produces a better time complexity, and the benchmarking of the routing algorithm with existing approaches, results in competitive outcomes.
Perceptions of Purity Messaging on Women and Secular Society
Authors:   , Hurd Madison
Published: January 2025

Purity culture was a movement created by evangelical Christian organizations in the United States and backed by marketing campaigns, media, churches, and sex education beginning in the 1990s. This movement was founded on the idea that young men and women should remain abstinent before marriage, thereby remaining in a state of "purity" for their future spouse. In purity culture messaging, women were positioned as sexual gatekeepers while men were framed as having little or no control over their sexual impulses, causing most of the purity expectation to fall on women. While the concept of remaining "pure" is not new, purity culture taught a new generation of women to feel ashamed and fearful of their sexuality and existed alongside an increasingly sexualized media landscape. This study analyzes purity culture and anti-purity culture themes that exist within television shows as well as how women perceive purity culture messaging and the effects this messaging had on their lives.
The Impact of Exclusionary Discipline on Students' Academic Performance in Title I Elementary Schools
Authors:   , McDaniel Lindsey G.
Published: January 2025

Exclusionary discipline is a consequence of behavior for students who break the student code of conduct. Extensive research about the effects that exclusionary discipline can have on secondary students, as evidenced by reduced graduation rates, has been conducted; but, research studies investigating the potential impact that exclusionary discipline can have on the academic outcomes of students at the elementary level have yet to be conducted. The use of exclusionary discipline is overrepresented in students with low socio-economic (SES) backgrounds; large populations of low-SES students are educated at Title I schools that receive federal funding to support academic growth. The purpose of this causal-comparative, non-experimental study was to investigate the impact that exclusionary discipline consequences had on fifth-grade students who attended all of the elementary schools within one north Texas school district during the 2018-2019 school year. In conjunction with the examination of the effect that the assignment of exclusionary discipline consequences can have on the academic outcomes of fifth-grade students, student-specific variables such as attendance at a Title I or non-Title I campus, student race, timing of exclusionary discipline assignment, and students in various educational programs were investigated to determine the potential impact of exclusionary discipline on fifth-grade students by student subgroup. Archival data such as the number of days a student spent in exclusionary discipline, student demographics, and students' scores on the State of Texas Assessments of Academic Readiness (STAAR) standardized test scores in reading and mathematics were utilized. A summary of findings, implications for administrators and schools, and recommendations for future research is also presented.
Teachers' Technology Adoption in Cross-Cultural Classroom: A Transformative Perspective
Authors:   , Meng Nanxi
Published: January 2025

In the current globalizing society, teachers are provided opportunities to move across their national borders to seek learning, professional development, and working opportunities. Technology-related professional development is particularly valued for teachers' sojourn to the technology intensive cultures. This qualitative cross-case study explored the K-12 Chinese language teachers' changes of teachers' application and perspective toward educational technology in cross-cultural teaching context through the lens of transformative learning theory. The qualitative data is collected from the interviews with 20 teacher participants in the four stages of cross-cultural sojourning: pre-departure, currently sojourning, post-sojourn, and immigrated. A qualitative cross-case analysis is conducted to compare the characteristics of teachers in different cases, and developed the complete process of the cross-cultural technology adoption and perspective. Factors contributed to the changes are also identified. Five issues related to the process are discussed. Implications and future directions were also included.
Factors Impacting Multicultural Teaching Competence among Counselor Educators: Ethnic/Racial Identity Development and Social Justice Orientation
Authors:   , Laird Amber N
Published: January 2025

Multicultural (MC) counseling and social justice (SJ) are foundational parts of counselors' professional identity, and they are fostered through a developmental process that counselor educators facilitate. The purpose of this study was to explore the relationship between counselor educators' ethnic/racial identity development (ERI), their social justice orientation (SJO) and their multicultural teaching competence (MCTC). MCTC was examined using the constructs of knowledge and sensitivity. Data was collected from a nationally distributed online survey. Data were analyzed using four hierarchical regression models in order to control for socially desirable responding. Results indicated that ERI was a significant predictor of MCTC-Knowledge (p < .001) and that SJO was a significant predictor of MCTC-Sensitivity (p < .001). Socially desirable responding was not significantly related to MCTC. Results suggest the importance of attending to ERI and SJO as separate processes in training future counselor educators.
King of the Merchandise: How Showa Era Paratexts Forever Changed the Godzilla Franchise
Authors:   , Cooper Dalton
Published: January 2025

The Godzilla media franchise is one of the longest running media franchises, which means the character himself has gone through many changes throughout the years. However, in American pop culture, the characters of Godzilla is perceived as a hero, a friend of humanity and defender of Earth. This reputation comes from the Showa Era, where Godzilla often fought on the side of humanity, rather than trying to destroy them as depicted in the original Gojira. In recent years, Toho, Godzilla's corporate owners, have been steering the King of the Monsters back into the villain role. Despite this tone shift by Godzilla's owners, American Godzilla paratexts still generally depict Godzilla as a hero. These depictions of Godzilla are used to maintain his status as a family friendly heritage brand and keep a door open for parents to introduce their children to the brand. Such a strategy allows Godzilla to survive into the modern day as an international powerhouse franchise.
Investigating the Effects of Sketchnoting on Undergraduate Students' Learning Strategies
Authors:   , Yang Xue
Published: January 2025

This study investigates the effects of sketchnoting, a visualized approach of notetaking, on learning strategies. The main questions asked were: What are the effects of sketchnoting on learners' learning strategies, including cognitive strategies (rehearsal, elaboration, organizational) and metacognitive strategies? Forty-eight undergraduate participants were divided into two groups, an experimental group, and a control group. Findings demonstrated a significant increase in cognitive learning strategies and metacognitive strategies in the experimental group. Other findings revealed that the aesthetic appeal of sketchnoting is the major reason motivating participants' sketchnoting behavior and the corresponding connection between design strategies and the learning strategies is the key of positive impacts of sketchnoting on learning strategies. Additional insights and implications are discussed.
Queerness, Futurity, and Desire in American Literature: Improvising Identity in the Shadow of Empire
Authors:   , Vastine Stephanie Lauren
Published: January 2025

This dissertation deploys queer theory and temporality to investigate the ways in which American authors were writing about identity at the turn of the twentieth century. I provide a more expansive use of queer theory, and argue that queerness moves beyond sexual and gender identity to have intersectional implications. This is articulated in the phrase "queer textual libido" which connects queer theory with affect and temporal theories. Queerness reveals itself on both narrative and rhetorical levels, and can be used productively to show the complex navigation between individual and national identity formation.
