Weaponized Nature: How the Environment Saved the Allies at Bastogne, December 16-23, 1944
Authors:   , Reader Darrell Ray
Published: February 2025

Many histories written by professional historians discuss the Battle of the Bulge; however, none of them incorporate the growing field of environmental history as a lens of analysis. This paper aims to address that hole in the scholarship by evaluating the impact that environmental factors exerted on the American army's ability to fight in and around Bastogne and St. Vith, Belgium during the first week of the battle. Had it not been for the environmental factors and the Americans' ability to make better use of the natural and manmade conditions than the Germans, the Allies would not have been able to achieve eventual victory. In the historiography of the battle, weather conditions are usually referenced only as the setting in which the fighting occurred. This paper goes further than simply using the environment and climate as a stage set. By looking at the way environmental conditions impacted strategic, operational, and tactical issues, a new perspective is opened up. The role that these environmental factors played is emphasized and shows that they had a greater effect on the outcome than scholars have previously credited. This paper uses first person accounts from participants, from the command level to the soldier in his foxhole, as well as unit histories, oral histories, and the vast amount of secondary sources to focus on and synthesize the effects that the environment had. Without exploiting the environmental factors that existed in the Ardennes, the American army would not have been able to hold off the German offensive.
Applications of a Model-Theoretic Approach to Borel Equivalence Relations
Authors:   , Craft Colin N.
Published: February 2025

The study of Borel equivalence relations on Polish spaces has become a major area of focus within descriptive set theory. Primarily, work in this area has been carried out using the standard methods of descriptive set theory. In this work, however, we develop a model-theoretic framework suitable for the study of Borel equivalence relations, introducing a class of objects we call Borel structurings. We then use these structurings to examine conditions under which marker sets for Borel equivalence relations can be concluded to exist or not exist, as well as investigating to what extent the Compactness Theorem from first-order logic continues to hold for Borel structurings.
Application-Focused Investigation of Monovalent Metal Complexes for Nanoparticle Synthesis
Authors:   , Kamras Brian Leon
Published: February 2025

Over the last 20 years, there has occurred an increase in the number, scope, and impact of nanomaterials projects. By leveraging the Surface Plasmon Resonance of metallic nanoparticles for labelling, sensing, and treatment, researchers have demonstrated the versatile utility of these nanomaterials in medicine. The literature provides evidence of use of simple, well-known chemistry for nanomaterials synthesis when the focus is new applications of nanomaterials. A case in point, is the synthesis of metallic nanoparticles, whereby HAuCl4, CuCl2, Cu(acac)2, and AgNO3 are typically employed as nanoparticle precursors. Unfortunately, the use of these precursors limits the number of applications available to these materials - particularly for AuNPs in medicine, where the byproducts of nanoparticle synthesis (most often surface-adsorbed reductants, toxic stabilizers, and growth directors) cause nanoparticles to fail clinical trials. Despite the several thousand publications detailing the advancements in nanoparticle therapeutics, as of 2017, there were only 50 FDA-approved nanoparticle formulations. Less than 10 were based on metallic nanoparticles. This is a problem because many of these nanoparticle therapeutics demonstrate potent cell killing ability and labeling of cells. A solution to this problem may be the use of weakly coordinated, monovalent metal complexes, which require only one electron to reduce them to their metallic state. Further, by designing nanoparticle syntheses around these monovalent complexes, we can employ weaker, environmentally friendly stabilizers. This strategy also forgoes the use of exogenous reducing agents, because the monovalent complexes can be reduced and stabilized by one reagent. Herein we investigate the use of Au(Me2S)Cl, [Cu(MeCN)4]BF4, and AgBF4 with green stabilizers to synthesize a variety of nanomaterials. We find that a range of sizes of spherical particles, as well as a range of sizes of gold triangular prisms can be synthesized by using techniques that follow this strategy.
Turkish Gazis' (Injured Veterans) Transition into Civilian Life
Authors:   , Celebi Mehmet
Published: February 2025

The aim of this study was to describe the dimensions of Turkish Gazis' transition to civilian life, to explore the main factors that make this process easier or more difficult, and their psychological integration, that is, specifically, satisfaction with their life. To that end, this study examined the impact of combat-related traumatic stressor (e.g., functional limitations), personal resources (social support, sense of mastery), perceived mental health on Turkish veterans' adjustment into civilian life and their psychological integration. The data was collected in Turkey in 2015 by the researcher with the help of Türkiye Harp Malulü Gaziler Şehit Dul ve Yetimler Derneği, a non-profit veteran organization. The final sample included 240 Turkish Gazis. The level of perceived transition into civilian life and veterans' life satisfaction were the dependent variables in this study. A series of ordinary least squares (OLS) regression was conducted. Hayes' PROCESS macro 3.0 was utilized to measure the direct, indirect and moderation effects of variables on transition and life satisfaction among Gazis. The results demonstrated that perceived available social support, perceived sense of mastery and mental health partially mediated the association between Gazis' functional limitations and transition into civilian life and they fully mediated the association between functional limitations and life satisfaction. Among control variables, only household income predicted transition into civilian life, and place of residence was the only significant predictor of life satisfaction. However, neither social support nor mastery had moderation effect on the relationship between functional limitations and dependent variables. Policy implications and suggestions for further studies are also provided at the end of the dissertation.
Healthy Eating in College Students: 24-Hour Dietary Recall and the Theory of Planned Behavior
Authors:   , Douglas Megan E.
Published: February 2025

The transition to college is marked by poorer eating behaviors. The Theory of planned behavior (TPB) represents a promising tool for predicting eating behaviors through the examination of attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), and intention (INT). Despite prior application of the TPB, there exist several key methodological issues in the literature addressing eating behaviors. The present study utilized an enhanced dietary assessment methodology, the ASA24 dietary recall, and a short-term prospective design to assess the healthy eating behaviors of emerging adults in college. Dietary recalls of 68 participants (average age = 20.76 years; 70.6% female; 70.6% non-Hispanic, 48.5% White, 22.10% Black/African American, 13.20% Asian) were analyzed using the Healthy Eating Index (HEI)-2010 scoring system. Results revealed that very few college students are meeting recommended dietary guidelines. Linear regression indicated that the indirect TPB variables (ATT, SN, and PBC) were related to INT (F[3,64] = 19.67, p < .001), although SN did not account for unique variance. Further, the direct TPB variables (INT and PBC) were related to HEI-2010 scores (F[2,65] = 4.00, p = .023); however, only PBC accounted for significant variance. Overall, findings suggest that more favorable attitudes relate to intention, but only perceived behavioral control consistently relates to actual healthy eating behavior.
Optimizing Production System Maintenance Policies when Cyber Threats are Considered
Authors:   , Ta Anh
Published: February 2025

In a production environment, physical and cyber-related failures become unavoidable because of the complexity of highly connected manufacturing systems and a finite equipment life cycle. The main purpose of this thesis is to investigate optimal maintenance outsourcing and replacement policies in the presence of cyber-threats, as well as policies to achieve channel coordination via cost subsidization. Although well-developed maintenance outsourcing literature has addressed many advanced and trending issues such as the costs and benefits of new technology adoptions, learning effects, forgetting effects, and systems with back-up machines, no study has looked at the effect of cyber threats on connected production systems. Besides filling this gap, this thesis addresses the most common replacement policies including preventive maintenance with minimal repairs and age replacement. The advent of the Internet of Things (IoT) has enabled the creation of "smart" manufacturing systems, However the resulting connected format makes these systems potential targets for cyber-attacks. Manufacturers have to face a difficult decision as to whether they should adopt costly security technologies or let the manufacturing systems be vulnerable to cyber-threats. This study develops a model addressing this dilemma by providing some insights into the effects of cost subsidization and installation of security systems on the system profit. Our findings suggest that a manufacturer can trade off cost subsidization to gain flexibility in the maintenance decision-making process. The study also provides evidence that, for a "smart" manufacturing system, the existence of a security system guarantees at least a marginal increase in system profit. With the help of an extensive numerical study, we provide guidelines for optimizing system profit and addressing the effect of various model parameters (such as a monetary parameter, failure rate and a cyber-attack related parameter) on the value of a security system.In the second part of this thesis, we build analytical models to deal with cyber-threats in the context of a production system that utilizes the age replacement policy. We propose two different scenarios involving cyber-threats. First, cyber-attacks do not disrupt the physical production system. In this case, we replace the broken components either when the system has a physical breakdown or when a predetermined amount of time (T) elapses. Second, we need to replace the system right after it suffers from a successful cyber-attack. Thus, we replace the system components if one of three following events happen, whichever comes first: (1) a successful cyber-attack, (2) a physical breakdown, or (3) a predetermined time (T) elapses. We analytically provide optimal policies to minimize the expected cost for these scenarios. Finally, we carry out sensitivity analyses to show the effect of different model parameters on the value of a cyber security system.
Perceptions of Associates to Embrace Technology Used in Teams in the Workplace
Authors:   , McGowan Michael T.
Published: February 2025

This study explores employees' desire to embrace both a legacy operating system and a new workflow engine utilized in the workplace. The goal is to better understand the partnership and relationship the users build with the technologies and how that impacts usage behavior. The research is centered on a mixed-method case study using survey and episodic interview techniques of data collection. Models and methodologies providing the foundation for this study include Venkatesh and Davis's technology acceptance model 2 (TAM 2) and Venkatesh, Morris, Davis, and Davis' unified theory of acceptance and use of technology (UTAUT) model, coupled loosely with concepts from Brooks and Atkinson's StructurANTion Theory. A new, adapted model is created to capture and understand the anthropomorphic characteristics users apply to the technology. This study yields important information for the future theoretical frameworks as elements such as trust and control, and descriptive variables like age and tenure have not factored into existing theoretical frameworks and models. Users can often anthropomorphize technology, viewing it as part of the social team to help improve their work. Through this lens, users expect information systems to be controllable and trustworthy to respond to their needs both alone and within the function of the team.
Hermeneutics, Environments, and Justice
Authors:   , Utsler David
Published: February 2025

Recent years have seen a growing interest in and the publication of more formal scholarship on philosophical hermeneutics and environmental philosophy--i.e. environmental hermeneutics. Grasping how a human understanding of environments is variously mediated and how different levels of meaning can be unconcealed permits deeper ways of looking at environmental ethics and human practices with regard to environments. Beyond supposed simple facts about environments to which humans supposedly rationally respond, environmental hermeneutics uncovers ways in which encounters with environments become meaningful. How we understand and, therefore, choose to act depends not so much on simple facts, but what those facts mean to our lives. Therefore, this dissertation explores three paths. The first is to justify the idea of an environmental hermeneutics with the hermeneutic tradition itself and what environmental hermeneutics is specifically. The second is to demonstrate the benefit of addressing environmental hermeneutics to environmental philosophy. I do this in this dissertation with regard to the debate between anthropocentrism and non-anthropocentrism, a debate which plays a central role in questions of environmental philosophy and ethics. Thirdly, I turn to environmental justice studies where I contend there are complementarities between hermeneutics and environmental justice. From this reality, environmental justice and activism benefit from exploring environmental justice more deeply in light of philosophical hermeneutics. This dissertation is oriented toward a continuing dialogical relation between philosophical hermeneutics and environments insofar as environments are meaningful.
Adult Attachment, Cultural Orientation and Sacrifice in Couples: A Comparison between American and Chinese Samples
Authors:   , Zhu Wenzhen
Published: February 2025

The present study examined the effects of adult attachment and cultural orientation on sacrifice behaviors and the corresponding emotional reactions, using a cross-cultural sample in the U.S. and China. Strain-tests protocol was utilized in this study, in which an individual (i.e., the asker) was asked to share with their romantic partner a personal goal that required a major sacrifice from their partner (i.e., the responder), and then entered a discussion to process their plan of carrying out this goal. The final sample included 115 couples from the U.S. and 99 couples from China. Results indicated that responder's attachment avoidance was negatively associated with sacrifice offered to their partners and they reported more positive emotions as a result. The interaction between attachment anxiety and nationality was significant. Specifically, in the U.S. sample, individuals with high attachment anxiety were more likely to offer sacrifice for their partners, but this effect was reversed in the Chinese sample. In addition, interdependent self-construal (ISC) was a significant moderator for the relation between attachment anxiety and sacrifice behavior. Individuals who endorsed higher ISC and higher anxious attachment were less likely to make sacrifice for their partner. Furthermore, when individual offered more sacrifice, they reported more positive emotions in general, but this effect was stronger in the Chinese sample than the U.S. sample. In addition, it was found that responders who endorsed higher ISC offered more sacrifice to their partner when asked to. These results advanced our understanding of the complex role of adult attachment in negotiating situations when partners in romantic relationships have different goals, as well as possible cultural differences in the expression of the attachment influences. The findings also highlighted the systemic perspective in understanding the roles of both partners' individual traits (i.e., attachment) and cultural values (i.e., interdependent self-construal) on their behaviors (i.e., sacrifice) in romantic relationships. Counseling implications, limitations, and future research directions were discussed.
Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review
Authors:   , Kabakci Maside
Published: February 2025

Researchers and publishing guidelines recommend reporting confidence intervals (CIs) not just along with null hypothesis significance testing (NHST), but for many other statistics such as effect sizes and reliability coefficients. Although CI and standard errors (SEs) are closely related, examining standard errors alone in simulation studies is not adequate because we do not always know if a standard error is small enough. Overly small SEs may lead to increased probability of Type-I error and CIs with lower coverage rate than expected. Statistical simulation studies generally examine the magnitude of the empirical standard error, but it is not clear if they examine the properties of confidence intervals. The present study examines confidence interval investigating and reporting practices, particularly with respect to coverage and bias as diagnostics in published statistical simulation studies across eight psychology journals using a systematic literature review. Results from this review will inform editorial policies and hopefully encourage researchers to report CIs.
Lithic Production at the Mesilla Phase Placitas Arroyo Site Complex Doña Ana County, New Mexico
Authors:   , Younger Alexandra Carla
Published: February 2025

This study of lithic analysis shifts attention from typological studies to explicitly behavioral analyses, complimenting studies of both intrasite and intersite patterns of variability and change. Analysis of several assemblages from the Placitas Arroyo site complex reveals changing patterns of raw material procurement and selection, core reduction strategies, as well as tool production and discard. The most striking result thus far is the quite uniform emphasis on flake production from well-prepared cores, and the near absence of manufacture or maintenance of bifacial tools, especially projectile points. Associated with common ground stone artifacts, the flaked stone materials may well represent intensive food processing. Regardless, the technological patterns being revealed by this approach illustrate a productive new means to gain insights into changing behaviors in the Jornada Mogollon cultural tradition.
A Survey of Solo, Chamber Music and Orchestral Excerpts Selected and Organized Pedagogically for the Intermediate Cellist
Authors:   , Zhou Lejing
Published: February 2025

The use of orchestral excerpts from standard music repertoire as a pedagogical means has been adopted by many instrumental pedagogues to train the advanced instrumentalist. This dissertation presents an innovative idea among the excerpt tradition by drawing excerpts from solo, chamber music and orchestral music to function as etudes for the intermediate level cellist. 320 music excerpts are drawn and organized under the headings of different technical categories in order to train the techniques within the context of quality music. The purpose of the dissertation is to introduce the young player to the concept that techniques and musical expression are not two separated entities, rather, techniques serve as a medium to convey the music.
A Global Spatial Model for Loop Pattern Fingerprints and Its Spectral Analysis
Authors:   , Wu Di
Published: February 2025

The use of fingerprints for personal identification has been around for thousands of years (first established in ancient China and India). Fingerprint identification is based on two basic premises that the fingerprint is unique to an individual and the basic characteristics such as ridge pattern do not change over time. Despite extensive research, there are still mathematical challenges in characterization of fingerprints, matching and compression. We develop a new mathematical model in the spatial domain for globally modeling loop pattern fingerprints. Although it is based on the well-known AM-FM (amplitude modulation and frequency modulation) image representation, the model is constructed by a global mathematical function for the continuous phase and it provides a flexible parametric model for loop pattern fingerprints. In sharp contrast to the existing methods, we estimate spatial parameters from the spectral domain by combining the exact values of frequencies with their orientations perpendicular to the fingerprint ridge flow. In addition, to compress fingerprint images and test background Gaussian white noise, we propose a new method based on periodogram spacings. We obtain the joint pdf of these m-dependent random variables at Fourier frequencies and derive the asymptotic distribution of the test statistic.
Igor Stravinsky: An Analytical Study of Programmatic Design of His Symphony in Three Movements
Authors:   , Anderson Rachel
Published: February 2025

Stravinsky seldom explained the intended theme of his works; however, he chose to do so with his Symphony in Three Movements. Stravinsky describes the first movement as a reflection on war films documenting scorched-earth tactics in China. He also states that the third movement is a reflection on the newsreels of goose-stepping soldiers, depicting the plot of the war in its entirety. In his descriptions, Stravinsky left out the second movement of the work. However, the movement already had a life of its own. The second movement expands a theme Stravinsky originally wrote for the movie The Song of Bernadette. The author, Franz Werfel, asked Stravinsky to compose music for the film when the two discussed the work and its central ideas. Although it did not appear in the film, Stravinsky recycled the music for the Symphony in Three Movements. In my opinion, the ideas of hope depicted in Werfel's novel are used by Stravinsky to evoke ideas of the importance of faith in the fallen world. My analysis aims to show the musical means used by Stravinsky to allow the central ideas from The Song of Bernadette to pervade the entirety of the Symphony in Three Movements.
From Property to Person: Understanding the Mediating Role of Control on Ovulation in the Female Consumer Experience
Authors:   , Njoroge Lydia
Published: February 2025

My aim is to design a research program that emphasizes inclusivity through empiricism rather than anecdotes and benevolent sexism. To accomplish this goal, I review and build on the work assessing the influence of fertility in the female consumer experience (FCE). Fertility, especially menstruation, has been used anecdotally for too long. This research was designed to address the gap in knowledge around the way in which women perceive advertisements. More specifically, the role fertility plays in the process women go through when assessing advertisements and offerings. Does a woman's desire to seek variety become reduced when she sees a rival endorsing the offering? If this is the case, then there is a need to find a mediating variable that can overcome this effect. Internal locus of control, the level a person feels they are in control of the outcomes in their lives, was selected as a starting point. Having a high internal LOC should buffer a person's perceptions of another as a threat. A cross-sectional design from a convenience sample of university students was used to address a series of five research questions: 1) Does fertility status influence locus of control, 2) Does fertility status influence rival assessment, 3) Does locus of control mediate rival assessment, 4) Does rival assessment influence advertisement assessment and purchase intent, and 5) Does external locus of control have more than a single factor? The results from the multiple one-way ANOVAs and linear regressions were not significant, but it was promising given the limitations of the study. Namely, the rate of unusable data combined with the rate of birth control use limited the final analyses to a sample of 62 cases. Additional considerations and future research directions are outlined in chapter 5.
A Pedagogical Guide to Brass Quintet Repertoire for the Trumpet
Authors:   , Bailey Megan
Published: February 2025

In today's rapidly changing performing arts market, trumpet players are required to be more versatile than ever. Trumpet performing jobs are diversifying and for a trumpeter, employment often requires the multi-faceted skill set that includes the ability to perform in all styles and settings ranging from jazz to classical, solo to large ensemble and brass quintet. As the demand for the brass quintet medium has grown, the study of chamber music repertoire has also become a common requirement in collegiate music programs. However, coaching in chamber music is limited, sometimes to as little as one hour per week. This coaching time is generally in the format of a single coach instructing the full chamber group, and therefore one-on-one instruction/attention is limited or nonexistent, leaving the onus of learning on the students, for whom these collegiate chamber music ensembles are their first exposure to the medium. While students have ample access to concentrated instruction for orchestral, band, and opera excerpts through the multitude of existing excerpt books, such a resource for trumpet players learning brass quintet repertoire does not yet exist. The purpose of this project is to create a succinct guide to the performance of the trumpet parts of standard brass quintet repertoire.

Authors:   , Jang Hyeyoun
Published: February 2025

Entr'actes and Sappho Fragments (1964) by English Composer Harrison Birtwistle represent extended notation, complex meters, and extended instrumental techniques. After World War II, the style and techniques of musical composition evolved considerably and musical trends began to continuously change. Conducting contemporary compositions requires new approaches in conducting methods. This paper examines a) introduce important elements of Birtwistle's compositions in the 1960, b) include an updated score of Entr'actes and Sappho Fragments (notated by the author), and c) provide a performance guide to the work.
Intergenerational Influences of Aggression: Social Cognitive Processes in Perspective-Taking and Aggressive Behavior in Young Adults' Romantic Relationships
Authors:   , Shamji Jabeen
Published: February 2025

The focus of the current study was to determine if SIP biases and perspective-taking serve as mediators between parental intimate partner violence (IPV), aggression, and interpersonal dominance in emerging adults' romantic relationships. We analyzed archival data comprised of self-report measures and TAT stories administered to 84 undergraduate students (women n = 62, M age = 21.73) between the ages 18 and 35. To test our hypotheses, we modified the social information processing model by incorporating perspective-taking, as measured through Interpersonal Decentering. Overall, we did not find significant association between witnessing parental IPV and Interpersonal Decentering maturity in college students. However, women's father-to-mother IPV was significantly negatively associated with Interpersonal Decentering maturity. For our mediation model, SIP aggressive responding biases were significantly associated with Interpersonal Decentering (average of story average scores) and with the presence of aggression in current romantic relationships; however, Interpersonal Decentering was not significantly predictive of aggression in current romantic relationships. Gender differences, study strengths and limitations, and future research directions are discussed.
The Impact of Technology-Based Music Classes on Music Department Enrollment in Secondary Public High Schools in the Northeastern United States
Authors:   , Freedman Barbara Ann
Published: February 2025

The purpose of this study was to examine if the implementation of a technology-based music class in public high schools in the northeastern United States had any significant impact on the overall music department enrollment and on enrollment in traditional performance ensemble courses, such as band and chorus, as they are the courses most offered in high schools in the United States. The two phases of the study included identifying eligible schools and collecting data from schools. A six-year history of music department and school enrollment data was collected from participating schools (n = 12). Individual music classes in each school were categorized as Band, Chorus, Orchestra, Technology-based, or Other Music Classes. Results found a statistically significant increase in overall Music Department enrollment and no statistically significant change in enrollment in Band or Chorus after the implementation of a technology-based music class. Reductions in enrollment did occur in Other Music classes. No significant change to the number of teachers in music departments was found. This study suggests that implementing a technology-based music classes may help increase overall music department enrollment without negatively impacting enrollment in traditional performance ensembles and may not necessitate funding for additional faculty.
Understanding the Micromechanism of Cyclic Loading Behavior of Ultrafine Grained Alloys
Authors:   , Shukla Shivakant
Published: February 2025

In the current study, we have investigated the cyclic loading behavior of conventional as well as novel alloy system exhibiting fine and ultrafine-grained structure. While in case of conventional alloy systems (here aluminum alloy AA5024), the effect of three different grain sizes was investigated. Improvement in fatigue properties was observed with decreasing grain size. The unique microstructure produced via Friction stir processing was responsible for the improved fatigue response. Additionally, microstructures consisting of a high fraction of special boundaries within the fine and ultrafine-grained regime were also subjected to cyclic loading. The hierarchical features introduced in the eutectic high entropy alloy deflected the persistent slip bands, responsible for fatigue cracking, thus resulted in delayed crack initiation and improved fatigue life. The selective nature of fatigue was learnt in the fine grain Al0.5CoCrFeNi, where the introduction of hierarchical features did not result in improved fatigue properties. The weak links in the microstructure, while not affecting the tensile properties, got exposed during cyclic loading. Further study on the medium entropy alloy revealed the inherent reason for the improved fatigue properties. The medium entropy alloys utilized the benefit of UFG single-phase FCC matrix. The UFG matrix showed signs of transformation of FCC phase into the HCP phase during fatigue deformation and hence exhibited improved work-hardening. Alongside atomic scale transformation, stacking faults and nano-twins can also be attributed for obtained cyclic properties.
The Public Health Response to an Ebola Virus Epidemic: Effects on Agricultural Markets and Farmer Livelihoods in Koinadugu, Sierra Leone
Authors:   , Beyer Molly
Published: February 2025

During the 2013/16 Ebola virus disease outbreak in West Africa, numerous restrictions were placed on the movement and public gathering of local people, regardless of if the area had active Ebola cases or not. Specifically, the district of Koinadugu, Sierra Leone, preemptively enforced movement regulations before there were any cases within the district. This research demonstrates that ongoing regulations on movement and public gathering affected the livelihoods of those involved in agricultural markets in the short-term, while the outbreak was active, and in the long-term. The forthcoming thesis details the ways in which the Ebola outbreak international and national response affected locals involved in agricultural value chains in Koinadugu, Sierra Leone.
Crystal Clear: A Performance Guide and Electronic Accompaniment of Mario Lavista's Marsias for Oboe and Crystal Glasses
Authors:   , Thompson Jonathan
Published: February 2025

Mario Lavista (b. 1943) is a dominant figure in Mexican classical music. In the second half of the twentieth century, he promoted the use of contemporary techniques, leading to a series of collaborations with expert instrumentalists to explore extended techniques. Marsias for Oboe and Crystal Glasses is one of those pieces. Due to the nature of contemporary techniques, different oboes and reed styles produce different effects with the same fingerings. This document analyzes the contemporary fingerings in the two published editions of the work in consideration of the long-scrape reed style and oboes commonly used in the United States. The contemporary techniques were played on twelve professional oboe models as a way to collect data on how the printed fingerings work. The data is the foundation for the performance guide, which details every contemporary technique in the work. The performance guide also provides comprehensive information about the crystal glass logistics. The document also presents an electronic accompaniment created with Max/MSP in the event that the crystal glasses or crystal glass players are unavailable.
Identifying Community Access to Veterinary Services in Southern Dallas
Authors:   , O'Neill Skye J
Published: February 2025

The Society for the Prevention of Cruelty to Animals of Texas in Dallas, Texas offers an array of services and programs to residents in southern Dallas and other areas. However, interest in the state of access to veterinary care has been questioned for southern Dallas residents. In an area that faces certain compounding stressors, such as food deserts and transportation difficulties, a lack of access to veterinary care for pet owners is considered an additional possible stressor. Pet owners in southern Dallas, along with the SPCA of Texas, contemplate how to best provide medical care for local pets. In this body of work, I describe community access to veterinary services in southern Dallas. I provide a resident-centered explanation based on in-depth interviews with locals that discuss the current state of access to veterinary services while simultaneously analyzing the links between access to veterinary care, the area of southern Dallas itself, and ongoing issues with roaming and stray dogs.
A Comparative Study of Polyphonic Techniques in Chang-Lei Zhu's Ballade for Solo Piano
Authors:   , Rong Xing
Published: February 2025

In Chinese contemporary piano music, large-scale piano compositions featuring innovative polyphonic musical languages are rarely found. Chang-Lei Zhu's Ballade for Solo Piano represents his development of contrapuntal techniques passed on from J. S. Bach and Dmitri Shostakovich in their polyphonic works for solo keyboard or piano. This study focuses on an analysis of Zhu's Ballade as an idiosyncratic composition that makes a significant contribution to the Chinese contemporary piano music repertory. Comparative analysis is made of Zhu's Ballade and J.S. Bach's Well-Tempered Clavier Books 1 and 2, as well as Dmitri Shostakovich's 24 Preludes and Fugues for Solo Piano, Op. 87. Zhu, a living Chinese composer born in 1976, uniquely writes the twenty variations of his Ballade based on the opening theme, a single melody in ten subphrases. This research lays out the close relationship of the opening theme with twenty variations in the Ballade. This study also illustrates how Zhu is an innovative voice in Chinese contemporary piano music literature. This comparative study constitutes the first scholarly study of Zhu's Ballade. Chapter 1 is an introduction to my comparative study. In chapter 2, comparisons on selected excerpts are conducted between Zhu's Ballade and J.S. Bach's WTC, Books 1 and 2, as well as Dmitri Shostakovich's Op. 87. Taking into consideration the pedagogical function of the Ballade, this study includes how the work can be used in Zhu's Ballade in piano pedagogy as an addition in chapter 3.
Critical Essay and Musical Score Accompanying the Original Music Composition, "East is East, and West is West (and Never the Twain Shall Meet)"
Authors:   , Buehler Alex
Published: February 2025

This document accompanies and explains the concepts used in the development of the composition, East is East, and West is West, (and Never the Twain Shall Meet). The process for generation and development of much of the musical content of the composition East is East, and West is West, (and Never the Twain Shall Meet) is the use of quoted musical materials. The second process, but equally as important, for development of the composition relies heavily on the idea of parallel development of modular ensembles and how the interactions created between them by sharing instrumentation can be a tool for development, as well as a challenge to the development of each module. Each module has an influence on at least one other module and is also influenced by at least one other module, creating a puzzle of interactions that must be navigated carefully when generating each individually. Both quotation and modularity are concepts employed by other composers, so this document also briefly explains how other composers have approached these concepts in their works in order to establish a historical relationship within the canon of western classical music to East is East, and West is West, (and Never the Twain Shall Meet).
Exploring Caffeyl-Lignin Biosynthesis in Cleome hassleriana and Polymerization of Caffeyl Alcohol in Arabidopsis thaliana
Authors:   , Harkleroad Aaron Djuanell
Published: February 2025

C-lignin (caffeyl-lignin) is a novel linear lignin polymer found in the seed coats of several non-crop plants, notably Vanilla planifolia (Vanilla), Jatropha Curcas (Jatropha), and Cleome hassleriana (Cleome). C-lignin has several advantages over normal G/S-lignin, found in the majority of lignocellulosic biomass, for valorization in the context of bioprocessing: less cross-linking to cell wall polysaccharides (less recalcitrant biomass), ordered linkages between monomers (homogeneous polymer), and no branching points (linear polymer). These properties make C-lignin an attractive replacement for native lignin in lignocellulosic biomass crops. The seed coats of Cleome hassleriana (Cleome) synthesize G-lignin during early seed maturation, then switch to synthesis of C-lignin during late maturation. This switch to C-lignin in Cleome seed coats is accompanied by loss of caffeoyl-CoA 3-O-methyltransferase (CCoAOMT) and caffeic acid 3-O-methyltransferase (COMT) activities, along with changes in transcript abundance of several lignin related genes. The focus of this research thesis is to understand the biochemical changes leading to C-lignin deposition in Cleome hassleriana seed coats, and to explore the ability of Arabidopsis thaliana seedlings to polymerize caffeyl alcohol to C-lignin. In this thesis, candidate transcripts were implicated in C-lignin biosynthesis by differential gene expression analysis of transcripts in seed coat tissues at 8-18 days after pollination (DAP) and in non-seed coat tissues. Three candidate genes were selected for recombinant expression and their in vitro kinetic properties were measured with potential substrates. Of the three candidates, a cinnamyl alcohol dehydrogenase (ChCAD5) was found to have high transcript levels during C-lignin formation and have a novel preference for converting caffealdehyde to caffeyl alcohol, the precursor of C-lignin. To determine if accumulation of caffeyl alcohol is sufficient for polymerization of C-lignin, Arabidopsis seedlings grown in a xylem induction system were supplied caffeyl alcohol. Polymerization of caffeyl alcohol was not found to occur in this Arabidopsis system, suggesting the need for a C-lignin specific polymerization mechanism.
Perceptions of Principals Learning to Lead Professional Learning Communities in a Fast-Growth District

Published: February 2025

The role of the principal has become increasingly complex and challenging. Recent emphasis has been placed on the role of principals as leaders who can build a culture of learning in schools to close the student achievement gap. Outside factors such as fast-growth in Texas have caused schools to change and grow quickly, which increases the learning demands placed on principals as they seek to develop the knowledge and skills needed for effective leadership. Developing and sustaining a professional learning community is a powerful strategy that has been found to improve teaching and learning, however developing professional learning communities requires skilled leadership. Limited research exists regarding how principals learn to implement and sustain professional learning communities within fast-growth districts, therefore, with this phenomenological qualitative research, I explored the lived experiences of seven principals within one fast-growth district in Texas to explore how they learned to develop and sustain a professional learning community.
Improving College Readiness: An Analysis of School-Level Factors

Published: February 2025

While much of the literature regarding college readiness focuses on student-specific factors, such as the individual's academic achievement; scores on college readiness assessments; and high school GPA, more research is needed to understand which school-level factors have the most influence on the percentage of college-ready graduates. The purpose of this research study was to explore the impact of various school-level factors (i.e., student demographics, college entrance exam facts, course offerings, and school characteristics) on the percentage of college ready graduates from Texas public high schools serving Grades 9-12 over a 3-year period. A multiple regression analysis conducted for each year's data resulted in three regression models, which identified various predictors (e.g. per-pupil instructional expenditures, teacher years of experience, taking advanced and/or dual credit coursework) of the percentage of college-ready graduates for schools accounting for 91.7%, 79.5%, and 65.6% of the explained variance in 2013, 2014, and 2015, respectively. Findings from this study provide educational leaders with data that could help them to make better-informed decisions regarding potential college readiness initiatives that, ultimately, could improve student performance.
Leadership Practices for Effective Equitable Learning Environments: A Case Study of Opportunity Gaps in a Rural District
Authors:   , Palazzetti Lisa A
Published: February 2025

In rural, low socioeconomic public schools, the diversity of the student population challenges teachers beyond their means to meet the wide-ranging needs of students, and therefore creating opportunity gaps. The purpose of this study was to explore one district's leadership support of teachers to create an equitable learning environment for all students. The present study built on existing literature by discovering leadership practices and perceived necessary supports for closing achievement gaps in K-12 classrooms. Through interviews with district and school administrators, classroom teachers, and observations of leadership meetings, the research for this case study included data collection and analysis. From the interview questions and observations, six themes emerged. The themes revealed from the data collected and analysis for this qualitative study aligned with the components of the conceptual framework, a sequence of initiative requirements for equitable learning environments. Developing a sequence of initiatives among all levels of educators could benefit sustainment of an equitable learning environment in Rural ISD. Recommended for further research is professional development to both leadership and teachers about professional learning communities (PLCs). In addition, study of parent education programs and how relationships achieve more parental involvement requires further research. A final recommendation for collegiate education preparation programs should include parental involvement, differentiation, and small group instruction as a requirement for teacher development when planning instruction for equitable lessons resulting in student achievement.
Is it Really a Different World? Colorism Then and Now in Black Sitcoms
Authors:   , Johnson Jasmine Cherese
Published: February 2025

This study focuses on dark-skinned, Black women's representation in Black sitcoms. Through a mixed-methods use of a comparative textual analysis and focus group, the content and context of episodes from A Different World and Dear White People are explored to illustrate portrayals of dark-skinned, Black women and how these portrayals affect dark-skinned, Black women's self-esteem. Its findings contribute to colorism research by exploring colorism in Black sitcoms. Because this topic is largely unexplored, this study seeks to begin a conversation about dark skinned, Black women's representation in Black sitcoms. The main objective is to ultimately improve their depictions and roles in Black sitcoms and hold Black creatives responsible for the role they play in promoting colorism and its ultimate effect on Black women's self esteem.
Biomedical Semantic Embeddings: Using Hybrid Sentences to Construct Biomedical Word Embeddings and its Applications
Authors:   , Shaik Arshad
Published: February 2025

Word embeddings is a useful method that has shown enormous success in various NLP tasks, not only in open domain but also in biomedical domain. The biomedical domain provides various domain specific resources and tools that can be exploited to improve performance of these word embeddings. However, most of the research related to word embeddings in biomedical domain focuses on analysis of model architecture, hyper-parameters and input text. In this paper, we use SemMedDB to design new sentences called `Semantic Sentences'. Then we use these sentences in addition to biomedical text as inputs to the word embedding model. This approach aims at introducing biomedical semantic types defined by UMLS, into the vector space of word embeddings. The semantically rich word embeddings presented here rivals state of the art biomedical word embedding in both semantic similarity and relatedness metrics up to 11%. We also demonstrate how these semantic types in word embeddings can be utilized.
