Keep Calm and Play On: The Effects of Grit, Mindfulness, and Goal Orientation on Sport Anxiety and Performance
Authors:   , Auerbach Alex
Published: February 2025

Achievement motivation theory suggests there are two primary approaches to achievement tasks: to appear competent or to develop a skill. These two different approaches to performance yield different affective and behavioral responses. Athletes holding a performance goal orientation tend to respond to challenges with behaviors exemplifying learned helplessness and increased anxiety. Athletes holding a mastery goal orientation tend to respond to challenges with greater effort and experience less sport-related anxiety. Individual athlete factors, such as grit, mindfulness, and achievement orientation may influence how athletes experience their environment and their levels of sport anxiety, and may interact with athletes' achievement motives to influence performance. I used hierarchical multiple regressions to test the main effects of feedback and mindfulness, and feedback and goal orientation, to determine if either mindfulness or goal orientation moderated the effects of feedback on performance. I also used simple regression to determine the relative predictive strength of mindfulness, grit, and goal orientation on athletes' experience of sport anxiety. Mindfulness, but not goal orientation, was a significant moderator of the feedback-shooting performance relationship, but particularly for athletes low in mindfulness; mastery-goal orientation, independently of feedback, was also a significant predictor of task performance. Mindfulness also emerged as the strongest predictor of reduced sport anxiety. These results suggest that, for athletes low in mindfulness, mastery-involving feedback may be especially helpful. Further, mindfulness may also reduce athlete's sport-related concentration disruption, worry, and somatic anxiety.

Authors:   , Free Corinne
Published: February 2025

The quality of care of residents in nursing homes receive is an important issue facing our society, and reliable methods to assess and measure important indicators of quality of care are necessary to ensure that nursing homes are providing adequate services. Previous researchers have developed methodologies to evaluate indicators of quality of care, including environmental conditions, resident conditions, resident activities, and staff activities using momentary-time sampling procedures across a variety of settings and populations. The purpose of the present study was to replicate and extend the time-sampling methodology used in previous research in two units in a nursing home.
Command Unity and the Air War against Germany
Authors:   , Truxal Luke
Published: February 2025

Starting in August 1942 the United States and United Kingdom started waging a strategic bombing offensive against Germany. Throughout the course of the 1942 and 1943 campaigns, American and British air forces struggled to gain the upper hand in the European air war. By November 1943 American and British defeats at the hands of the German Air Force, or Luftwaffe, had placed the air war in doubt. By February 1944, the air war had turned around in favor of the Allies. This dramatic turn of events has been explained by historians in a number of ways. The most popular narrative is that the introduction of the long range escort fighter, the P-51 "Mustang," turned the tide in the air war. Another narrative is that there was a change in the fighter tactics. Starting in January 1944, American fighters stopped defending the bombers and started aggressively pursuing German fighters. Yet, these analyses do not include a major command changes that took place from November to January 1944. After his appointment to command of Supreme Headquarters Allied Expeditionary Force, General Dwight D. Eisenhower used his position centralize all of the major air commands in Europe under his control. By unifying the air commands, the Allies were able to better coordinate and concentrate their air against Germany. In February 1944 the Allies focused their air forces against the Luftwaffe ultimately wearing down German fighter strength. After finally removing a major obstacle impending the strategic air war against Germany, the Allies concentrated their air forces against transportation and oil targets. The destruction of these two major economic systems crippled Germany's ability to fight the Allies in 1944 and 1945. By changing the command structure, Eisenhower was able to use his air forces in successful coordinated strategic air offensives that the Allies had previously been incapable of accomplishing.
Rearranging an Infinite Universe: Literary Misprision and Manipulations of Space and Time, 1750-1850
Authors:   , Tatum Brian Shane
Published: February 2025

This project explores the intersection of literature and science from the mid-eighteenth century to the mid-nineteenth century in the context of this shift in conceptions of space and time. Confronted with the rapid and immense expansion of space and time, eighteenth and nineteenth-century philosophers and authors sought to locate humans' relative position in the vast void. Furthermore, their attempts to spatially and temporally map the universe led to changes in perceptions of the relationship between the exterior world and the interior self. In this dissertation I focus on a few important textual monuments that serve as landmarks on this journey. During the eighteenth and nineteenth centuries, the intersection of literary and scientific texts transformed perceptions of space and time. These transformations then led to further advancements in the way scientific knowledge was articulated. Imagination became central to scientific writing at the same time it came to dominate literary writing. My project explores these intersecting influences among literature, astronomy, cosmology, and geology, on the perceptions of expanding space and time.
On-Loom Fabric Defect Inspection Using Contact Image Sensors and Activation Layer Embedded Convolutional Neural Network
Authors:   , Ouyang Wenbin
Published: February 2025

Malfunctions on loom machines are the main causes of faulty fabric production. An on-loom fabric inspection system is a real-time monitoring device that enables immediate defect detection for human intervention. This dissertation presented a solution for the on-loom fabric defect inspection, including the new hardware design—the configurable contact image sensor (CIS) module—for on-loom fabric scanning and the defect detection algorithms. The main contributions of this work include (1) creating a configurable CIS module adaptable to a loom width, which brings CIS unique features, such as sub-millimeter resolution, compact size, short working distance and low cost, to the fabric defect inspection system, (2) designing a two-level hardware architecture that can be efficiently deployed in a weaving factory with hundreds of looms, (3) developing a two-level inspecting scheme, with which the initial defect screening is performed on the Raspberry Pi and the intensive defect verification is processed on the cloud server, (4) introducing the novel pairwise-potential activation layer to a convolutional neural network that leads to high accuracies of defect segmentation on fabrics with fine and imbalanced structures, (5) achieving a real-time defect detection that allows a possible defect to be examined multiple times, and (6) implementing a new color segmentation technique suitable for processing multi-color fabric defects. The novel CIS-based on-loom scanning system offered real-time and high-resolution fabric images, which was able to deliver the information of single thread on a fabric. The algorithm evaluation on the fabric defect datasets showed a non-miss-detection rate on defect-free fabrics. The average precision of defect existed images reached above 90% at the pixel level. The detected defect pixels' integrity—the recall scored around 70%. Possible defect regions overestimated on ground truth images and the morphologies of fine defects similar to regular fabric pattern were the two major reasons that caused the imperfection in defect pixel locating. The experiments showed the defect areas on multi-color fabrics could be precisely located under the proposed color segmentation algorithm.
The Influence of Visual Sources of Nutrition-Oriented Information on Young Adults' Dieting Efforts
Authors:   , Stark Hillary Lynn
Published: February 2025

The goal of this study was to investigate visual sources of nutrition information relied upon by young adults, specifically college-aged students between 18-30, as this is an under-represented population within current academic literature. A sample of more than 700 18- to 30-year-old college students were surveyed regarding their use of nutrition-driven information, with specific questions regarding the participants' awareness and use of the Food and Drug Administration's standardized nutrition facts labels, as well as the use of smartphone applications for tracking one's food and beverage consumption on a regular basis. Using structural equation modeling, a statistically significant theoretical model was developed with regards to individuals finding greater long-term satisfaction in their dieting efforts if they tracked their consumption on a regular basis, with even greater significance being found through the aid of smartphone applications for recording consumption. An analysis of the content of three online diet and exercise-driven brands was also conducted to determine the currently optimal social media platform for nutrition information exchange, and to identify the type of diet-driven information that generates the greatest amount of engagement within an online network. Of the social media platforms analyzed, Instagram proved to be the most optimal for nutrition information-exchange, and that humorous and relevant content shared by dieting brands generated the greatest engagement within their online networks. These studies confirmed that formal visual sources of information, specifically the FDA's nutrition fact labels, are not regularly acknowledged nor implemented within this population, but rather informal visual sources of information, such as content shared across social media channels and the use of smartphone applications, are heavily relied upon when dieting within the young adult population. These research implications are relevant and timely to academics, health professionals, and governmental entities, as they support the need for greater educational endeavors towards increasing the public's nutrition and food literacies, as well as provide an improved strategy for individuals who are dieting through a model for increased satisfaction in one's dieting efforts.
Educator Perceptions of Forces Influencing Implementation of a Statewide Writing Portfolio Assessment
Authors:   , Morgan Christi A.
Published: February 2025

Leaders of the 84th Texas Legislature drafted and ratified HB 1164 (2015), prompting the Texas Education Agency to pilot a portfolio assessment option for assessing student writing growth and proficiency. The purpose of this study was to identify the perceptions, characterize the experiences, and identify the forces that influenced initial implementation of the statewide writing pilot. Through interviews with district leaders and the collection of open-ended questionnaires from participating educators, a collective case study method was conducted and allowed for analysis of cross-case themes. The identification of restraining and driving forces affecting implementation of the statewide pilot program provided insight into considerations for next steps in the evaluation of student writing achievement and growth. Three primary perceptions emerged as restraining forces influencing implementation: influences of inadequate funding, inconsistencies of implementation, and navigation of multiple assessment systems. Six primary themes related to driving forces influencing implementation were identified: using sociocultural and authentic methods, engaging in reflective practices, increasing volume and variety of writing opportunities, assessing student growth, aligning methods of instruction and assessment, and reducing stress for students. Effective professional development, dependent upon funding and staffing allocations; two-way channels of communication for participant reflection and feedback; and effective assessment structures must be aligned with the purpose and goals of a student-centered assessment system, which requires collaborative conversations between policy makers, state-level decision makers, and educators.
Assessing and Treating Oral Reading Deficits in Children with Developmental Disabilities
Authors:   , Braun Emily Catherine
Published: February 2025

A brief reading assessment and preference assessment were conducted with three participants with developmental and learning disabilities (i.e., two participants were diagnosed with Autism, the third participant was diagnosed with intellectual disability) who did not acquire fluent reading in previous individualized instruction. The results of the brief reading assessment were analyzed in an alternating treatment design and a preference assessment was conducted to determine the participants' preferred reading intervention. Following the results of the two assessments, a reading intervention that matched effectiveness with preference when possible or favored effectiveness when a match was not possible. The selected interventions (and later combined interventions) were implemented for each participant using an A-B-A-C or an A-B-A-C-D design. The results suggest that the four reading strategies are effective options for improving reading fluency. Also, a brief reading assessment can help identify an effective reading strategy. The results are discussed in the context of fluency gains, limitations, and implications for future research.
Lipogenic Proteins in Plants: Functional Homologues and Applications
Authors:   , Cai Yingqi
Published: February 2025

Although cytoplasmic lipid droplets (LDs) are the major reserves for energy-dense neutral lipids in plants, the cellular mechanisms for packaging neutral lipids into LDs remain poorly understood. To gain insights into the cellular processes of neutral lipid accumulation and compartmentalization, a necessary step forward would be to characterize functional roles of lipogenic proteins that participate in the compartmentalization of neutral lipids in plant cells. In this study, the lipogenic proteins, Arabidopsis thaliana SEIPIN homologues and mouse (Mus Musculus) fat storage-inducing transmembrane protein 2 (FIT2), were characterized for their functional roles in the biogenesis of cytoplasmic LDs in various plant tissues. Both Arabidopsis SEIPINs and mouse FIT2 supported the accumulation of neutral lipids and cytoplasmic LDs in plants. The three Arabidopsis SEIPIN isoforms play distinct roles in compartmentalizing neutral lipids by enhancing the numbers and sizes of LDs in various plant tissues and developmental stages. Further, the potential applications of Arabidopsis SEIPINs and mouse FIT2 in engineering neutral lipids and terpenes in plant vegetative tissues were evaluated by co-expressing these and other lipogenic proteins in Nicotiana benthamiana leaves. Arabidopsis SEIPINs and mouse FIT2 represent effective tools that may complement ongoing strategies to enhance the accumulation of desired neutral lipids and terpenes in plant vegetative tissues. Collectively, our findings in this study expand our knowledge of the broader cellular mechanisms of LD biogenesis that are partially conserved in eukaryotes and distinct in plants and suggest novel targets that can be introduced into plants to collaborate with other factors in lipid metabolism and elevate oil content in plant tissues.
Development of an Observation System to Measure Narratives of Teaching Interactions
Authors:   , Hines Dalai C
Published: February 2025

Having a measurable way to analyze how staff members describe teaching interactions is important for staff training and building a community of effective and caring practice. The purpose of this project, part of a larger program, is to develop a measurement system that captures descriptions of connected events (narratives) during teaching interactions. This project involved development of a reliable measurement system that discriminates between experienced and novice narratives of teaching interactions (contingency arrangements) across multiple cases of instruction. The participants were employees of a non-profit agency serving children with autism and their families. They volunteered to participate in the study. The development of the code included the systematic selection of high quality autism intervention video clips and asking participants to view the clips and describe events, and then coding responses. The participant narratives were then categorized by themes and analyzed. The results are described in the context of usefulness and limitations of the measurement systems. A mutielement design comparing responses across stimulus conditions was used to evaluate the sensitivity of the measurement system in discriminating between novice and experienced interventionists.
A Text Analysis of Data Science Career Opportunities and U.S. iSchool Curriculum
Authors:   , Durr Angel Krystina
Published: February 2025

Data science employment opportunities of varied complexity and environment are in growing demand across the globe. Data science as a discipline potentially offers a wealth of jobs to prospective employees, while traditional information science-based roles continue to decrease as budgets get cut across the U.S. Since data is related closely to information historically, this research will explore the education of U.S. iSchool professionals and compare it to traditional data science roles being advertised within the job market. Through a combination of latent semantic analysis of over 1600 job postings and iSchool course documentation, it is our aim to explore the intersection of library and information science and data science. Hopefully these research findings will guide future directions for library and information science professionals into data science driven roles, while also examining and highlighting the data science techniques currently driven by the education of iSchool professionals. In addition, it is our aim to understand how data science could benefit from a mutually symbiotic relationship with the field of information science as statistically data scientists spend far too much time working on data preparation and not nearly enough time conducting scientific inquiry. The results of this examination will potentially guide future directions of iSchool students and professionals towards more cooperative data science roles and guide future research into the intersection between iSchools and data science and possibilities for partnership.
A Random Walk Version of Robbins' Problem
Authors:   , Allen Andrew
Published: February 2025

Robbins' problem is an optimal stopping problem where one seeks to minimize the expected rank of their observations among all observations. We examine random walk analogs to Robbins' problem in both discrete and continuous time. In discrete time, we consider full information and relative ranks versions of this problem. For three step walks, we give the optimal stopping rule and the expected rank for both versions. We also give asymptotic upper bounds for the expected rank in discrete time. Finally, we give upper and lower bounds for the expected rank in continuous time, and we show that the expected rank in the continuous time problem is at least as large as the normalized asymptotic expected rank in the full information discrete time version.
Friction Stir Welding of Dissimilar Metals
Authors:   , Wang Tianhao
Published: February 2025

Dissimilar metals joining have been used in many industry fields for various applications due to their technique and beneficial advantages, such as aluminum-steel and magnesium-steel joints for reducing automobile weight, aluminum-copper joint for reducing material cost in electrical components, steel-copper joints for usage in nuclear power plant, etc. The challenges in achieving dissimilar joints are as below. (1) Big difference in physical properties such as melting point and coefficient of thermal expansion led to residual stress and defects. (2) The miscibility issues resulted in either brittle intermetallic compound layer at the welded interface for miscible combinations (such as, aluminum-steel, aluminum-copper, aluminum-titanium, etc.) or no metallurgical bonding for immiscible combinations (such as magnesium-copper, steel-copper, etc.). For metallurgical miscible combinations, brittle intermetallic compounds formed at the welded interface created the crack initiation and propagation path during deformational tests. (3) Stress concentration appeared at the welded interface region during tensile testing due to mismatch in elastic properties of dissimilar materials. In this study, different combinations of dissimilar metals were joined with friction stir welding. Lap welding of 6022-T4 aluminum alloy/galvanized mild steel sheets and 6022-T4 aluminum alloy/DP600 steel sheets were achieved via friction stir scribe technology. The interlocking feature determining the fracture mode and join strength was optimized. Reaction layer (intermetallic compounds layer) between the dissimilar metals were investigated. Butt welding of 5083-H116 aluminum alloy/HSLA-65 steel, 2024-T4 aluminum alloy/316 stainless steel, AZ31/316 stainless steel, WE43/316 stainless steel and 110 copper/316 stainless steel were obtained by friction stir welding. The critical issues in dissimilar metals butt joining were summarized and analyzed in this study including IMC and stress concentration.

Induced Water Drinking during a Discrete Trial Procedure Using a Variable-Ratio Schedule of Reinforcement with a Canine
Authors:   , Frier Tracy
Published: February 2025

Falk's pivotal 1961 study showed that rats would drink excessive amounts of water when exposed to a time based schedule of reinforcement. Since then, schedule-induced drinking or polydipsia, has been demonstrated with several species and with a variety of different behaviors. Rats, the most commonly used animal, have been shown to drink excessive amounts of water under a variety of different time based schedules of reinforcement; exclusively during a free operant procedure. The current study shows that water drinking can be induced during a discrete trial procedure, and instead of using a time-based schedule of reinforcement, this study used a variable-ratio schedule of reinforcement. The results showed that excessive water drinking was induced under these conditions with a canine.

The Effects of Modeling and Coaching on Verbal Narratives of Teaching Interactions by Novice Behavior Analysts
Authors:   , Lambert Lindsey L
Published: February 2025

Research has shown that well-trained staff within early and intensive behavioral intervention (EIBI) provide more effective treatment. An important part of training is learning the vocabulary and concepts of treatment. This aids in conceptual understanding of the principles and procedures. The process of learning behavioral concepts also develops the necessary verbal repertoire needed to communicate among members of a community of practice; a group of people who have common reinforcers and are working toward a common goal. Learning to tact a series of sequential descriptions, or verbally narrate, exemplary teaching interactions should be a goal when teaching behavior analysis because it is how we, as a community, interact and establish an understanding of behavior analysis. The purpose of the current study is to train novice behavior analysts to narrate exemplary intervention sequences that are responsive, flexible, and effective teaching interactions. The effects of the training were evaluated using a multiple baseline design across training conditions, replicated across 3 participants. The results suggest that the training was effective in increasing the number of narrative statements as well as the number of narrative statements related to five critical features of a teaching interaction and the relations between those features. The results are discussed in the context of future research directions, including studies of correspondence between verbal behavior and teaching interaction performance.
Strategies for the Creation of Spatial Audio in Electroacoustic Music
Authors:   , Smith Michael Sterling
Published: February 2025

This paper discusses technical and conceptual approaches to incorporate 3D spatial movement in electroacoustic music. The Ambisonic spatial audio format attempts to recreate a full sound field (with height information) and is currently a popular choice for 3D spatialization. While tools for Ambisonics are typically designed for the 2D computer screen and keyboard/mouse, virtual reality offers new opportunities to work with spatial audio in a 3D computer generated environment. An overview of my custom virtual reality software, VRSoMa, demonstrates new possibilities for the design of 3D audio. Created in the Unity video game engine for use with the HTC Vive virtual reality system, VRSoMa utilizes the Google Resonance SDK for spatialization. The software gives users the ability to control the spatial movement of sound objects by manual positioning, a waypoint system, animation triggering, or through gravity simulations. Performances can be rendered into an Ambisonic file for use in digital audio workstations. My work Discords (2018) for 3D audio facilitates discussion of the conceptual and technical aspects of spatial audio for use in musical composition. This includes consideration of human spatial hearing, technical tools, spatial allusion/illusion, and blending virtual/real spaces. The concept of spatial gestures has been used to categorize the various uses of spatial motion within a musical composition.
Process Improvement of Surface Preparation of Structuraly Bonded Helicopter Detail Parts
Authors:   , Tafoya Keirsten Breann
Published: February 2025

The objective of this study was to increase the bond strength at the surface interface of a thin stainless-steel panel for structural bonding on a helicopter. To achieve this objective, six activation methods for applying the coating to the panel in the surface preparation process are presented and explored. Adhesion and roughness tests were conducted to determine which method consistently initiates the etch and improves the bond at the surface. Based on the test results, three methods proved to be effective in initiating the etch. Of the three effective methods, only one method exhibited significantly improved bond strength at the surface interface as well as consistently initiated the etch in solution. The applicability of this method is discussed, and recommendations are presented for further study.
The Effects of an Instructional Package on the Emergence of Novel Intraverbals in Children with Autism
Authors:   , Macias Heather A.
Published: February 2025

We evaluated the effects of an instructional package on the emergence of novel intraverbals in children diagnosed with autism. Participants were two boys with a diagnosis of autism who had tact and listener repertoires for common objects and events, some intraverbal responses, and showed an ability to learn new intraverbal responses through direct instruction prior to participating in the study. Tact training, listener training, sorting training, and mixed training (listener and tact training) were conducted with each participant, with a probe to test for emergent intraverbals following each training step. If some emergence was seen during a probe following a training step, probes were conducted with the remaining sets to test for emergence in those sets as well. Multiple-exemplar training was conducted following the training steps if all targets within a set did not meet the criterion for emergence during probes. Results showed that for one participant, all four training steps, in addition to multiple-exemplar training, were needed to see emergence in all targets during probes for two sets, with the last two sets requiring only tact training before all targets had emerged during probes. The second participant required only tact training during three sets, with listener training required for one target in one set before all targets in all sets emerged during probes.
Comparative Study of Thermal Comfort Models Using Remote-Location Data for Local Sample Campus Building as a Case Study for Scalable Energy Modeling at Urban Level Using Virtual Information Fabric Infrastructure (VIFI)
Authors:   , Talele Suraj Harish
Published: February 2025

The goal of this dissertation is to demonstrate that data from a remotely located building can be utilized for energy modeling of a similar type of building and to demonstrate how to use this remote data without physically moving the data from one server to another using Virtual Information Fabric Infrastructure (VIFI). In order to achieve this goal, firstly an EnergyPlus model was created for Greek Life Center, a campus building located at University of North Texas campus at Denton in Texas, USA. Three thermal comfort models of Fanger model, Pierce two-node model and KSU two-node model were compared in order to find which one of these three models is most accurate to predict occupant thermal comfort. This study shows that Fanger's model is most accurate in predicting thermal comfort. Secondly, an experimental data pertaining to lighting usage and occupancy in a single-occupancy office from Carnegie Mellon University (CMU) has been implemented in order to perform energy analysis of Greek Life Center assuming that occupants in this building's offices behave similarly as occupants in CMU. Thirdly, different data types, data formats and data sources were identified which are required in order to develop a city-scale urban building energy model (CS-UBEM). Two workflows were created, one for an individual scale building energy model and another one for CS-UBEM. A new innovative infrastructure called as Virtual Information Fabric Infrastructure (VIFI) has been introduced in this dissertation. The workflows proposed in this study will demonstrate in the future work that by using VIFI infrastructure to develop building energy models there is a potential of using data for remote servers without actually moving the data. It has been successfully demonstrated in this dissertation that data located at remote location can be used credibly to predict energy consumption of a newly built building. When the remote experimental data of both lighting and occupancy are implemented, 4.57% energy savings was achieved in the Greek Life Center energy model.
Multi-Function and Flexible Microwave Devices
Authors:   , Zhou Mi
Published: February 2025

In this dissertation, some multi-function and flexible RF/microwave devices have been studied to solve the issues in the modern microwave system designs. First, a power divider with two functions is proposed. The first function is a zero-phase delay power divider using zero-phase impedance transformer. The second function is a power divider with impedance transforming property. To achieve the first function, the two arms are treated as zero-phase impedance transformers. When the phase requirement is relaxed, the second function is obtained. Shunt transmission line stubs are employed to connect the isolation resistor, which provides great flexibility in the design. Then, a balun with transparent termination impedance and flexible open arms is designed. The design parameters of the balun are independent to the port impedance. This property allows the balun to work with different system impedances. Furthermore, the two output ports of the balun do not need to be connected together, which enables the device to have a very flexible structure. Finally, the continuous research of a tunable/reconfigurable coupler with equal output impedance is presented. In addition to the tunable/reconfigurable responses, unequal output impedance property is added to the microstrip line coupler. To shrink the size at the low frequency and make it easy for fabrication at higher frequency, the coupler is redesigned using lumped components. To validate the design theories, simulations are carried out. Moreover, prototypes of the power divider and the balun are fabricated and characterized. The simulation and measurement results match well with the theoretical calculation.
Enlightening Dark Tourism in Nepal
Authors:   , Thapa Magar Asha
Published: February 2025

This study aims to examine the motivation, experience and benefits of Nepalese domestic tourists visiting the seismic memorial sites after the 25 April 2015 earthquake (known as Gorkha earthquake). A total of 403 surveys was gathered from seismic sites of Nepal (Kathmandu, Bhaktapur and Patan). Data were tested to analyze why the tourists are interested in disaster sites and how their experience during their visit impact the benefits of the visits. Additionally, partial least square structural equation modeling (PLS-SEM) was employed to test the relationships among tourist motivations, experiences, and perceived benefits at the dark tourism sites in Nepal. Among the five motivational factors discovered, the empirical results depict that emotional reaction is the strongest factor of the dark tourism motivation, affecting both cognitive and affective experiences. Additionally, this study confirms that cognitive experience is more influenced by dark tourism motivations than affective experience. Among the four experience factors examined in the study, self-reflection is found to have the strongest impact of three aspects of perceived dark tourism benefits, such as knowledge gain, fulfillment, and appreciation. Overall, the findings of the study provide important implications to the management sectors of dark tourism sites, enhancing the importance of providing cognitive experiences (i.e. distributing the educational materials about the dark tourism events and offering the knowledgeable tour guide who can guide the sites) and affective experience of the tourists (storytelling about the events, organizing educational and volunteering programs at the sites). Further, this study contributes to the limited literature in the context of dark tourism and provide important managerial and practical implications based on the case of Nepal earthquake in 2015.
Shaping Hagiography through Liturgy: Music for the Patron Saints of Three Cathedrals in Medieval Aquitaine
Authors:   , Recek Andrea
Published: February 2025

While the development of hagiography over time has long attracted the attention of medievalists, scholars have not fully explored the critical role of the liturgy in prompting and transmitting these changes. This dissertation examines the liturgies for the patron saints of three musical and ecclesiastical centers in medieval Aquitaine: the cathedrals of Saint-Trophime in Arles, Saint-Just-et-Saint-Pasteur in Narbonne, and Saint-Étienne in Toulouse. Through the music, texts, and ritual actions of the liturgy, the clerical communities of these three institutions reinforced some aspects of their patron saint's legendary biography and modified others. Yet the process unfolded differently at each cathedral, revealing the particular preferences of the canons of each community as well as their changing circumstances during the Middle Ages. In Arles, the office for St. Trophime, which was likely composed at the cathedral, shows dramatic changes in the saint's hagiography. The clerics in Narbonne also composed an office for their patron saints but did not substantially change the details of Justus and Pastor's legendary biography. In Toulouse, the canons selected from among the preexisting repertoire of chants and texts available for St. Stephen, crafting liturgies that were particular to Saint-Étienne within a clearly Aquitanian context. By revealing the ways in which the clerics of Saint-Trophime, Saint-Just, and Saint-Étienne shaped the legendary biographies of their patron saints, my work provides new insights into the ways in which clerical communities throughout Latin Christendom shaped and reshaped the hagiographic portraits of their patron saints through the creation, compilation, and celebration of new liturgies.
A Multi-Methodology Study of the Historic Impact of Soft Systems Methodology and Its Associated Data Visualization Approach in the Context of Operations and Business Strategy
Authors:   , Warren Scott Joseph
Published: February 2025

The purpose of this three-essay dissertation was to expand knowledge and theory regarding soft systems methodologies (SSMs) and data visualization approaches in business, engineering, and other social sciences. The first essay depicts a bibliometric analysis study of the historic impacts of SSM from 1980-2018 on business, engineering, and other social sciences fields. This study found 285 articles that described or employed SSM for research and included outcomes such as top SSM authors, author citation impacts, common dissemination outlets, time-bound distribution of publications, and other relevant findings. This study provided a picture of who, what, why, when, and where SSM has had the greatest impact on academic thought and practice. The second essay presents research on the academic impact of Systemigrams, an associated data visualization approach, finding examples of conceptual or research development that employed Systemigrams to depict complex problem situations. Recommendations for improvement of designing these data visualizations to increase their field use resulted from this study. The final essay leverages a selection of the articles as use cases to produce a grounded theory study to identify phenomena that arose from the use of SSM for operations and firm strategy research. This study identified two broad themes including (i) scope, structure, and process challenges and (ii) performance and evaluation limitations. These themes were explained by six patterns that emerged from the publications. Each produced change recommendations for SSM process, practice, and reporting to support its continued viability and adoption in business and operations research.

Published: February 2025

The purpose of this study was to investigate direct and interaction effects of cultural intelligence and social support on the adjustment of international students to U.S. higher education. Hierarchical multiple regression analyses were conducted to test (a) if cultural intelligence was a predictor for adjustment of international students to U.S. higher education; (b) if social support was a predictor for adjustment of international students to U.S. higher education; and (c) if there was an interaction effect between cultural intelligence and social support on international students' adjustment to U.S. higher education. The participants included 262 international students from a southwestern university. The results found only social support from the university was a significant predictor of international students' adjustment. There was no interaction effect between cultural intelligence and social support from any sources on international students' adjustment.
An Instructional Guide to Teaching Dan Beaty's Woodsprite and Waterbug Collection for Intermediate Piano Students and Instructors
Authors:   , Hung Sophie
Published: February 2025

The purpose of this dissertation is to offer a pedagogical guide to Woodsprite and Waterbug Collection (1977) by Dan Beaty (1937-2002) through an analysis of its pedagogical values and teaching applications. This set consists of twelve short, intermediate-level pieces, featuring various contemporary idioms. Each piece is also pedagogically written to help intermediate students to refine specific pianistic techniques beyond the elementary level. In addition, Beaty's collection expands students' musical vision and musicianship for more advanced studies via the incorporation of contemporary music theory and techniques.

Authors:   , Farmer Shelley Kristine
Published: February 2025

To improve online learning pedagogy within the field of paralegal education, this study investigated how paralegal students and paralegal instructors perceived the effectiveness of synchronous and asynchronous online paralegal courses. Survey results were analyzed using independent samples t-test and correlational analysis, and indicated that overall, paralegal students and paralegal instructors positively perceived synchronous and asynchronous online paralegal courses. Paralegal instructors reported statistically significant higher perceptions than paralegal students: (1) of instructional design and course content in synchronous online paralegal courses; and (2) of technical assistance, communication, and course content in asynchronous online paralegal courses. Instructors also reported higher perceptions of the effectiveness of universal design, online instructional design, and course content in synchronous online paralegal courses than in asynchronous online paralegal courses. Paralegal students reported higher perceptions of asynchronous online paralegal course effectiveness regarding universal design than paralegal instructors. No statistically significant differences existed between paralegal students' perceptions of the effectiveness of synchronous and asynchronous online paralegal courses. A strong, negative relationship existed between paralegal students' age and their perceptions of effective synchronous paralegal courses, which were statistically and practically significant. Statistically significant relationships existed between paralegal instructors' perceptions of effective synchronous online paralegal course and the number of courses taught by the paralegal instructor. Lastly, this study provided practical applicability and opportunities for future research.

The contact patterns among individuals can significantly affect the progress of an infectious outbreak within a population. Gathering data about these interaction and mixing patterns is essential to assess computational modeling of infectious diseases. Various self-report approaches have been designed in different studies to collect data about contact rates and patterns. Recent advances in sensing technology provide researchers with a bilateral automated data collection devices to facilitate contact gathering overcoming the disadvantages of previous approaches. In this study, a novel unilateral wearable sensing architecture has been proposed that overcome the limitations of the bi-lateral sensing. Our unilateral wearable sensing system gather contact data using hybrid sensor arrays embedded in wearable shirt. A smartphone application has been used to transfer the collected sensors data to the cloud and apply deep learning model to estimate the number of human contacts and the results are stored in the cloud database. The deep learning model has been developed on the hand labelled data over multiple experiments. This model has been tested and evaluated, and these results were reported in the study. Sensitivity analysis has been performed to choose the most suitable image resolution and format for the model to estimate contacts and to analyze the model's consumption of computer resources.
Silver(I) and Copper(I) Complexes from Homoleptic to Heteroleptic: Synthesis, Structure and Characterization

A plethora of novel scientific phenomena and practical applications, such as solid-state molecular solar cells and other optoelectronic devices for energy harvesting and lighting technologies, have catalyzed us to synthesize novel compounds with tunable properties. Synthetic routes, single crystal structures, and spectral and materials properties are described. Reactions of Ag(I) and Cu(I) precursors with various types of ligands -- including the azolates, diimines, and diiphosphines -- lead to the corresponding complexes in high yield. Varying the metal ions, ligands, synthetic methods, solvents, and/or stoichiometric ratio can change the properties including the molecular geometry or packing structure, reactivity, photophysical and photochemical properties, semiconducting behavior, and/or porosity of the functional coordination polymers obtained. For solar cells purposes, the absorption energy can be extended from the ultraviolet (UV) region, through the entire visible (Vis) region, onto a significant portion of the near-infrared (NIR) portion of the solar spectrum with high absorption coefficients due to the infinite conjugation of Cu(I) with diimine ligands. Twenty-eight crystal structures were obtained by conventional crystal growth methods from organic solvents, whereas their bulk product syntheses also included "green chemistry" approaches that precluded the use of hazardous organic solvents. The resulting products are characterized by powder x-ray diffraction (PXRD), Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), UV/Vis/NIR absorption/diffuse reflectance/photoluminescence spectroscopies, and thermogravimetric analysis (TGA). Regarding the scientific phenomena investigated, the highlighting work in this dissertation is the discovery of novel bonding/photophysical/optoelectronic properties of the following materials: a black absorber with absorption from 200- 900 nm, a very stable compound with a bright green luminescence obtained by a solventless reaction, and a novel coordination polymer showing uncommon interaction of Ag(I) with three different types of diimine ligands simultaneously.
