The Effect of Professional Learning Communities on Perceived Teacher Self-Efficacy
Authors:   , Prince Coryn Elizabeth
Published: February 2025

This qualitative case study examined the effect of PLCs on teacher self-efficacy, and whether the type of PLC structure on each campus affected efficacy. The overarching research question that guided the study was, to what extent does perceived teacher self-efficacy change as a result of the practice of PLCs? Participants were selected using purposive and convenience sampling. Ten teachers and two principals on two different campuses participated in teacher focus groups and one-on-one principal interviews, respectively. The available literature on the topics of professional development, professional learning, teacher collaboration, and teacher self-efficacy yielded the discovery that collaborative practices can be used to improve a school and/or district or used to enhance positive practices that already occur. This study adds to the body of research as it develops the area of teacher efficacy and influence of PLCs. Using the coding software, NVivo, focus group data were coded into themes and further comparisons were made with categories derived and saturated until conclusions were drawn. The data show teacher self-efficacy increases as a result of PLCs when teachers are able to experience positive feedback from teammates, shared leadership, trust and honesty, and a freedom to fail. For those teachers who are not on a campus where PLCs are present, the data suggest they created their own PLCs as the need arose. These teachers experienced all of the same benefits of those teachers on a campus where a formal PLC structure exited; however, their stress level was higher.
Socially Just Principals' Pursuit of Cultural Proficiency
Authors:   , Kelly Elizabeth
Published: February 2025

The purpose of this research was to explore how the personal and professional experiences of school leaders strengthened or hindered their ability to engage in social justice leadership to advance educational equity and encourage culturally proficient practices in their schools. I employed a descriptive multi-case study and the research was viewed through a conceptual framework that included social justice, equity, and the five elements of cultural proficiency. Five principals from three different school districts were selected as participants. They represented elementary, middle and high schools. Interviews consisted of semi-structured face to face interviews with each principal participant and one focus group interview with five participants. Each participant also provided a cultural autobiography. Findings revealed while principals may care deeply about providing equitable opportunities for students, the interest does not supplement knowledge, skills, experience, and support. The information gained from this study can inform the practice of school leaders, and the way in which districts and programs of educational leadership prepare school leaders to serve and address the needs of all students as public schools become more culturally diverse.

Authors:   , Sulaiman Ahmad M.
Published: February 2025

Isolating novel phages using Streptomyces azureus, which produces antibiotic thiostrepton, as a host, and characterizing the genomes may help us to find new tools that could be used to develop antibiotics in addition to contribute to the databases of phages and specifically, Streptomyces phages. Streptomyces phages Alsaber, Omar, Attoomi, Rowa, and ZamZam were isolated using during this study. They were isolated from enriched soil and sequenced by Illumina sequencing method. They were isolated from three different geographical regions. They are siphoviridae phages that create small clear plaques with a diameter of approximately 0.5-1 mm, except for Rowa which has cloudy plaques, and they have varied sizes of their heads and tails. ZamZam was not characterized at this time. The sequencing shows that they are circular genome with 3' sticky overhang and various genomes' sizes with high percentage of GC content with the average of 66%. Alsaber was classified under sub-cluster BD3, while Omar was categorized under sub-cluster BD2. They share the same cluster of Cluster BD. Rowa was placed in Cluster BL and Attoomi is currently a singleton that does not fit into an established cluster. Alsaber yields 76 putative genes with no tRNA, Omar 81 putative genes with 1 tRNA. Attoomi 53 putative genes with no tRNA, and Rowa with 61 orfs and 7 tRNA. Rowa also was a putative temperate phage due to its lysogenic activity, and Row was not able to reinfect the lysogenic strain, S. azureus (Rowa). All of the isolated phages infected S. indigocolor, while only Attoomi and Rowa were able to infect S. tricolor. Upon completion of this project, we acquired more data and understanding of S. azureus phages and Actinobacteriophage in general, which will expand the scale of future research of Streptomyces bacteriophages.
Contemporary Double Bass Techniques: An Advanced Technical Approach
Authors:   , Meyer Mariechen
Published: February 2025

Diverse practicing methods are evidence of the importance of applying creativity in our practice regimes. Regardless of a player's technique - traditional or modern - it must be regularly practiced and then applied. One of the most common ways to do that is through practicing technical exercises, which generally means the practice of scales, arpeggios and etudes. These exercises generally function as a warm-up regime for all musicians, but this regime doesn't necessarily provide enough reference for the player in the learning process of a new piece. Adapting exercises to address technical difficulties in a newly learned piece can provide the player with a wide range of practice methods to use, to be creative, to be more aware while practicing, and to build a solid technical foundation for the newly learned piece. Two well-known pedagogues who applied this approach are German bassist Ludwig Streicher and Czech violinist Otakar Ševčik. By implementing analytical studies and composing exercises based on the standard repertoire, Ševčik and Streicher became highly influential teachers in the 20th century. Their work serves as a model in achieving the purposes of this dissertation: the assessment of technical difficulties and compilation of a technique booklet based on six unaccompanied contemporary solo pieces written as required works for the solo competition of the International Society of Bassists' biennial convention since 2007.
An Ethnographic Inquiry and Evaluation into the Student's Perspective and Experience with Improvement Science at Algoma School District
Authors:   , Williams Jodi M.
Published: February 2025

Using ethnographic research in the form of an outcomes assessment, this project aims to unpack and evaluate the experiences of students and significance of the key concepts shared during the Live Algoma-Improvement Science course/and associated projects during the 2015-2016 and 2016-2017 school years. Through the use of evaluative techniques such as interviews, focus groups, and a survey, I endeavor to both strengthen and inform the work Live Algoma is doing and highlight to the community and other stakeholders the valuable impact of this initiative on the students. As part of the Improvement Science course, students from the Algoma School District were trained on key concepts such as failing forward, PDSA, and ways of being to empower them to better handle individual project management, life challenges, and goal setting. While this project was expansive in overall scope, this outcome evaluation sought to understand the retention and internalization by program participants of key concepts imparted from the Improvement Science course and related projects. The findings provide strategic and targeted insights into the success of the course and opportunities for refinements in future Improvement Science courses and school and community projects with Live Algoma and the Algoma School District.
Changes in Student Borrowing at Private Not-for-Profit Four-Year Institutions in the United States
Authors:   , Namalefe Susan A.
Published: February 2025

Trends in tuition and financial aid policy have increased the number of students who borrow for higher education and the aggregate debt students acquire. Most research on student borrowing over the years has analyzed the effects of borrowing and the prospects of indebtedness on individual students' choices and persistence. However, dynamics at the institutional level such as the need to ensure a stable flow of resources may accelerate or slow down student borrowing. Drawing on resource dependence theory, this study examined changes in student borrowing at private not for profit four year institutions in the US to identify trends and implications. A fixed effects regression analysis was applied to panel data from the Delta Cost project and the National Association of College and University Business Officers. Analytical focus was on the financial and enrollment characteristics of private not for profit four-year institutions, the relationship between these characteristics and student borrowing, and whether these relationships are stable or change over time. Findings revealed that the financial and enrollment characteristics of private not for profit institutions during the study period were characterized by gradual variation. The results also revealed that most of the financial characteristics were predictive of student borrowing and that these relationships vary with time. Evidence from this study cautions higher education policy makers that high tuition dependence and the attendant student loan burden may disadvantage some students. Policy makers concerned about providing equitable access to higher education to all student subpopulations should try to moderate competition among institutions and tuition rises that intensify student borrowing. Institutional practices such as tuition maximization and selective price discrimination must be moderated so that financial aid, including loans, can realize the objective of encouraging fairness and choice in higher education entry.
Population Dynamics and Community Structure of Mosquitoes (Diptera: Culicidae) Recorded in Denton, Texas from 2005 to 2015
Authors:   , Hambrick Bethany Lynn
Published: February 2025

A population survey was conducted on the mosquito species recorded in Denton, Texas for the years of 2005 to 2015. Data used in this project were obtained from an ongoing, long-term surveillance program led by the City of Denton and conducted through the University of North Texas. Research focused on the population dynamics and community structure of mosquitoes collected within urban areas of Denton, Texas in relation to certain environmental variables. A total of 80,837 female mosquitoes were captured and represented 38 species found under the following genera: Aedes, Anopheles, Coquillettidia, Culex, Culiseta, Mansonia, Orthopodomyia, Psorophora, Toxorhynchites, and Uranotaenia. Culex quinquefasciatus was the most abundant species followed by Aedes vexans. Seasonal patterns of the most abundant species revealed high variability throughout the study. Container breeders were most abundant in August and those that breed in floodwaters were most abundant in the months of May and September. Samples were tested for arbovirus presence through the Texas Department of State Health Services in Austin, Texas and multiple pools tested positive for West Nile virus throughout the study. Stepwise multiple regression and Spearman's rank correlation analyses were performed to examine the relationship between the mosquito community and environmental variables. Data revealed that temperature, precipitation, and dew point were the most important variables influencing the mosquito population in the City of Denton.
Detecting Component Failures and Critical Components in Safety Critical Embedded Systems using Fault Tree Analysis
Authors:   , Bhandaram Abhinav
Published: February 2025

Component failures can result in catastrophic behaviors in safety critical embedded systems, sometimes resulting in loss of life. Component failures can be treated as off nominal behaviors (ONBs) with respect to the components and sub systems involved in an embedded system. A lot of research is being carried out to tackle the problem of ONBs. These approaches are mainly focused on the states (i.e., desired and undesired states of a system at a given point of time to detect ONBs). In this paper, an approach is discussed to detect component failures and critical components of an embedded system. The approach is based on fault tree analysis (FTA), applied to the requirements specification of embedded systems at design time to find out the relationship between individual component failures and overall system failure. FTA helps in determining both qualitative and quantitative relationship between component failures and system failure. Analyzing the system at design time helps in detecting component failures and critical components and helps in devising strategies to mitigate component failures at design time and improve overall safety and reliability of a system.
Hauntology Man
Authors:   , Wright Adam Michael
Published: February 2025

Hauntology Man, a 48-minute documentary, follows former UNT Professor, Dr. Shaun Treat, as he leads a walking ghost tour of downtown Denton, Texas. As the expedition moves from storefront to storefront, each stop elicits a new tale. But, as Dr. Treat points out, the uncertainties of history are the real ghosts. That is, rather than simply presenting a "haunted history" of Denton, it's more accurate to say this movie's center resides at the precipice of a "haunting history." Not all ghost stories need spectres. Sometimes not knowing is ghost enough.
The Identification and Participation of Latino Students in Advanced Mathematics Courses
Authors:   , Blanchard Myrna Elizabeth
Published: February 2025

Using a phenomenological approach, this qualitative study examined the perspectives of Latino parents and their involvement in the decision of their child to enroll in an advanced mathematics course in sixth grade. Since enrollment in Algebra I in high school is said to be a strong predictor of college attainment and with the growing number of Latino students across the nation, this study has the potential to help district and campus leaders establish whole-school systems for communicating with Latino parents to encourage their children to enroll in advanced mathematics courses at earlier grades. Participants in this study included four sixth-grade students enrolled in an advanced mathematics course, four enrolled in regular mathematics, their mother or father, two mathematics teachers, a school counselor, and two district administrators. Data analyzed included audio recordings of semi-structured interviews of each of the participants. The findings suggested that the district has proactively developed a systematic process of creating that includes six data points to create a student profile of students that will do well in advanced mathematics. This process is helping the district close the gap between total Latino school enrollment and the enrollment of Latino students in advanced mathematics. The findings also suggested that specific communication with parents about the importance of enrollment trajectories might influence the enrollment of students into advanced mathematics courses at earlier grades.
Evaluating Sea-Level Rise Hazards on Coastal Archaeological Sites, Trinity Bay, Texas
Authors:   , Elliott Patrick
Published: February 2025

This study uses the predictive modeling program Sea-Levels Affecting Marshes Model (SLAMM) to evaluate sea-level rise hazards, such as erosion and inundation, on coastal archaeological sites with a vertical rise of sea level of .98 meters from 2006 to 2100. In total 177 archaeological site locations were collected and georeferenced over GIS outputs maps of wetlands, erosion presence, surface elevation, and accretion. Wetlands data can provide useful information about characteristics of the wetland classes, which make a difference in the ability for coastal archaeological sites to combat sea level rise. Additionally, the study evaluated predicted erosion of archaeological sites by presence or absence of active erosion on a cell-by-cell basis. Elevation map outputs relative to mean tide level allowed for a calculation of individual archaeological site datums to use NOAA tidal databases to identify the potential for their inundation. Accretion maps acquired from the SLAMM run determined the potential for the archaeological site locations to combat rising sea levels and potentially provide protection from wave effects. Results show that the most significant hazard predicted to affect coastal archaeological sites is inundation. Approximately 54% of the total archaeological sites are predicted to be inundated at least half the time by 2100. The hazard of erosion, meanwhile, is expected to affect 33% of all archaeological sites by the end of the century. Although difficult to predict, the study assumes that accretion will not be able to keep pace with sea-level rise. Such findings of hazards prove that SLAMM is a useful tool for predicting potential effects of sea-level rise on coastal archaeological sites. With its ability to customize and as it is complementary, it provides itself not only an economical choice but also one that is adaptable to many scenarios.
Three Essays on Information Security Risk Management
Authors:   , Ogbanufe Obiageli
Published: February 2025

Today's environment is filled with the proliferation of cyber-attacks that result in losses for organizations and individuals. Hackers often use compromised websites to distribute malware, making it difficult for individuals to detect. The impact of clicking through a link on the Internet that is malware infected can result in consequences such as private information theft and identity theft. Hackers are also known to perpetrate cyber-attacks that result in organizational security breaches that adversely affect organizations' finances, reputation, and market value. Risk management approaches for minimizing and recovering from cyber-attack losses and preventing further cyber-attacks are gaining more importance. Many studies exist that have increased our understanding of how individuals and organizations are motivated to reduce or avoid the risks of security breaches and cyber-attacks using safeguard mechanisms. The safeguards are sometimes technical in nature, such as intrusion detection software and anti-virus software. Other times, the safeguards are procedural in nature such as security policy adherence and security awareness and training. Many of these safeguards fall under the risk mitigation and risk avoidance aspects of risk management, and do not address other aspects of risk management, such as risk transfer. Researchers have argued that technological approaches to security risks are rarely sufficient for providing an overall protection of information system assets. Moreover, others argue that an overall protection must include a risk transfer strategy. Hence, there is a need to understand the risk transfer approach for managing information security risks. Further, in order to effectively address the information security puzzle, there also needs to be an understanding of the nature of the perpetrators of the problem – the hackers. Though hacker incidents proliferate the news, there are few theory based hacker studies. Even though the very nature of their actions presents a difficulty in their accessibility to research, a glimpse of how hackers perpetrate attacks can be obtained through the examination of their knowledge sharing behavior. Gaining some understanding about hackers through their knowledge sharing behavior may help researchers fine-tune future information security research. The insights could also help practitioners design more effective defensive security strategies and risk management efforts aimed at protecting information systems. Hence, this dissertation is interested in understanding the hackers that perpetrate cyber-attacks on individuals and organizations through their knowledge sharing behavior. Then, of interest also is how individuals form their URL click-through intention in the face of proliferated cyber risks. Finally, we explore how and why organizations that are faced with the risk of security breaches, commit to cyberinsurance as a risk management strategy. Thus, the fundamental research question of this dissertation is: how do individuals and organizations manage information security risks?

Identity and Career Maturity in Kinesiology Students
Authors:   , Johnson Malia
Published: February 2025

The purpose of this study was to explore athletic identity, identity foreclosure, and career maturity in a sample of undergraduate college students currently enrolled in kinesiology and physical education classes at a university in the southern United States. Students were provided with an internet link that requested them to complete a demographic survey, the Athletic Identity Measurement Scale (AIMS), the foreclosure subscale of the Extended Objective Measure of Ego Identity Status, and the Attitude Scale (Form A-2) of the Career Maturity Inventory. Examination of the Pearson moment correlations indicated that the higher the sport participation during high school, the greater the athletic identity and identity foreclosure, and lower the career maturity attitudes. ANOVAs were performed to examine differences between males (n = 123) and females (n = 183), kinesiology (n = 181) and non-kinesiology majors (n = 125), and white (n = 144) and non-white students (n = 162) on athletic identity, identity foreclosure, and career maturity. Results showed that males scored significantly higher on athletic identity and identity foreclosure, and significantly lower on career maturity than females. Kinesiology students had scores significantly higher on athletic identity and identity foreclosure, and lower on career maturity. Finally, individuals that identified their ethnicity as White had higher athletic identity, lower identity foreclosure, and significantly higher career maturity than individuals who identified as an ethnicity other than white. Although the relationships in this study are in line with what has been found in previous research, the relationships among this sample of undergraduate students were weak. Future research should replicate the study using a measurable level of sport skill level. Future research should also consider introducing an intervention with a career development program, and track participants' athletic identity, identity foreclosure, and career mature before, during, and after implementation of the program.
Identification of the Neurobiological Basis of Hemodynamic Responses Correlated with Cognitive Stroop Task Performance After an Acute Bout of Aerobic Exercise
Authors:   , Pal Amrita
Published: February 2025

Cardiovascular activities may increase the brain blood flow improving neuronal activities leading to improved cognition. Consequently, the effects of an acute bout of moderate intensity aerobic exercise on brain hemodynamics and its correlation with cognitive color-word Stroop task performance were tested. The Stroop tasks were congruent (color matches word) and incongruent (color does not match word). Prefrontal (PFC) and motor cortex (MC) blood flow was recorded by fNIRS (functional near-infrared spectroscopy) while the subject was performing the Stroop tasks before and after the 30 minutes of exercise or equivalent time of rest controls (checking for practice effects). Ninety human subjects of age 24± 6, 20 ADHD (attention-deficit hyper-activity disorder), 27 High-BMI (>25), 29 males were recruited. Reaction time ‘RT' decreased (p<0.05) after exercise for both the congruent (12%) and incongruent (10%) Stroop tasks, compared to 8% with practice alone. Accuracy did not change after practice or exercise. HR changes after exercise correlated (p<0.05) with better accuracy and faster RT for the incongruent Stroop task. In general, a metabolic lag occurred in the neuronal deoxy- hemoglobin (Hb) signals behind the systemic oxy-Hb signals. PFC showed the highest effect sizes of Stroop task-responsive systemic hemodynamic changes compared to baseline irrespective of rest or exercise. Yet, PFC showed most significant (p<0.001) neuronal hemodynamic changes between the before and after exercise sessions, and these changes were opposite for right and left PFC, and opposite for congruent and incongruent Stroop tasks. Correlating the RT and mistakes with hemodynamics for both the Stroop tasks revealed that, after exercise, neuronal hemodynamic changes occurred at both PFC and MC associated with faster RT (p<0.05), and systemic hemodynamic responses occurred at PFC correlated (p<0.05) with mistakes. Overall, it was concluded that exercise changed the neuronal hemodynamic changes affecting speed; however, neuronal metabolic changes did not occur sufficiently to help improve accuracy in all subjects.
Computational Approaches for Analyzing Social Support in Online Health Communities
Authors:   , Khan Pour Hamed
Published: February 2025

Online health communities (OHCs) have become a medium for patients to share their personal experiences and interact with peers on topics related to a disease, medication, side effects, and therapeutic processes. Many studies show that using OHCs regularly decreases mortality and improves patients mental health. As a result of their benefits, OHCs are a popular place for patients to refer to, especially patients with a severe disease, and to receive emotional and informational support. The main reasons for developing OHCs are to present valid and high-quality information and to understand the mechanism of social support in changing patients' mental health. Given the purpose of OHC moderators for developing OHCs applications and the purpose of patients for using OHCs, there is no facility, feature, or sub-application in OHCs to satisfy patient and moderator goals. OHCs are only equipped with a primary search engine that is a keyword-based search tool. In other words, if a patient wants to obtain information about a side-effect, he/she needs to browse many threads in the hope that he/she can find several related comments. In the same way, OHC moderators cannot browse all information which is exchanged among patients to validate their accuracy. Thus, it is critical for OHCs to be equipped with computational tools which are supported by several sophisticated computational models that provide moderators and patients with the collection of messages that they need for making decisions or predictions. We present multiple computational models to alleviate the problem of OHCs in providing specific types of messages in response to the specific moderator and patient needs. Specifically, we focused on proposing computational models for the following tasks: identifying emotional support, which presents OHCs moderators, psychologists, and sociologists with insightful views on the emotional states of individuals and groups, and identifying informational support, which provides patients with an efficient and effective tool for accessing the best-fit messages from a huge amount of patient posts to satisfy their information needs, as well as provides OHC moderators, health-practitioners, nurses, and doctors with an insightful view about the current discussion under the topics of side-effects and therapeutic processes, giving them an opportunity to monitor and validate the exchange of information in OHCs. We proposed hybrid models that combine high-level, abstract features extracted from convolutional neural networks with lexicon-based features and features extracted from long short-term memory networks to capture the semantics of the data. We show that our models, with and without lexicon-based features, outperform strong baselines.
The Design and Development of Lightweight Composite Wall, Roof, and Floor Panels for Rigid Wall Shelter
Authors:   , Artman Jeremy J
Published: February 2025

This thesis presents a research effort aimed at developing a stronger, lighter, and more economic shelter using rigid wall panels. Reported herein is insulation research, wall and roof panel design and testing, floor section modeling and strength calculations, and cost and weight calculations. Beginning stages focus on developing solid wall and roof panels using cold-formed steel corrugated sheathing and members, as well as polyurethane spray foam for insulation. This research includes calculating uniform load density, to determine the overall strength of the panel. The next stage focuses on the flexural strength of the wall and roof panels, as well as finalizing the floor design for the shelter. This includes determining maximum flexural strength required to meet the standards set by the project goal. Direct strength method determined the correct thickness of members to use based on the dimension selected for the design. All Phases incorporated different connection methods, with varied stud spacing, to determine the safest design for the new shelters. Previous research has shown that cold-formed steel corrugated sheathing performs better than thicker flat sheathing of various construction materials, with screw and spot weld connections. Full scale shear wall tests on this type of shear wall system have been conducted, and it was found that the corrugated sheathing had rigid board behavior before it failed in shear buckling in sheathing and sometimes simultaneously in screw connection failures. Another aspect of the research is on the insulation of the wall panels. Research was conducted on many different insulation options for the mobile facilities. Specifically, insulation made of lightweight material, is non-combustible, added rigidity to the structure, and has high thermal properties. Closed cell polyurethane spray foam was selected for full-scale testing in this research. Closed cell polyurethane adds extra rigidity, is lighter than common honeycomb insulation, and has a higher R-value. Several polyurethane foam companies were studied for this research, and promising products were identified. The research focuses on the impacts of the polyurethane foam to the structural performance of the wall panels. Both shear and 4-point bending tests were completed to investigate the strength and behavior of the cold-formed steel framed wall panels with polyurethane foam insulation. Comparing the cost and weight of the current shelter, and the new design is reported herein. The material studies, specimen details, and test results are reported in this thesis.
Framing the DREAM Act: An Analysis of Congressional Speeches
Authors:   , Koo Yilmin
Published: February 2025

Initially proposed in 2001, the Development, Relief, and Education for Alien Minors Act (DREAM Act) continues to be relevant after nearly 20 years of debate. The year 2010 was significant because there seemed to be some possibility of passage. This study investigated the ways in which the DREAM Act discourse was framed that year by supporters and opponents. Selected Congressional speeches of three supporters and three opponents were analyzed using the approach to frame analysis developed by Schön and Rein. Accordingly, attention went to each individual's metacultural frame (i.e., culturally shared beliefs), policy frame (i.e., identification of problem and presentation of possible solution), and rhetorical frame (i.e., means of persuading the audience). Attention also went to the shared framing among supporters and the shared framing among opponents as well as differences in framing across the two groups. Although speakers varied in framing the issue, there were commonalities within groups and contrasts between groups. For supporters, the metacultural frame emphasized equity/equal opportunity, fairness, and rule of law; for opponents, the metacultural frame stressed rule of law, patriotism, and national security. For supporters, the policy frame underscored unfairness as the problem and the DREAM Act as the solution; for opponents, the policy frame emphasized the DREAM Act as the problem and defeating the DREAM Act as the solution. Rhetorical frames also differed, with the supporters making much use of testimonial examples and the opponents making much use of hyperbole. The study illustrates (1) how the same named values and beliefs can have dramatically different interpretations in metacultural framing, as were the case for rule of law and American dream in this discourse; (2) how the crux of an issue and its intractability can be seen by looking at how the problem is posed and how the solution is argued, and (3) how speakers strengthen their claims with particular kinds of rhetorical devices. Through descriptions of political positioning on the DREAM Act, the study contributes to understandings of ongoing issues regarding the lives of undocumented young people who have received and are receiving education in the U.S.
Exploration of Information Sharing Structures within Makerspaces: A Mixed Methods Case Study of Dallas Makerspace and Its Users
Authors:   , Hadidi Rachel
Published: February 2025

Makerspaces are a popular, new concept being implemented in public, academic, and school libraries, and as stand-alone spaces. The literature reflects the newness of the topic with a limited number of articles and studies and even less about the users of makerspaces themselves. This study explored information sharing behaviors in the Dallas Makerspace as an informal learning environment and described their preferred method of information transfer from one member to another. It employed a mixed methods methodology using surveys, interviews and observations. The study identified how the rules and policies in place at the makerspace influence the information seeking process and how the Dallas Makerspace exchanges information effectively. Dallas Makerspace is one of the largest non-profit work groups in its size, and this research study answers how information is exchanged in an informal environment.
Fence, Flavor, and Phantasm: Balancing Japanese Musical Elements and Western Influence within an Historical and Cultural Context
Authors:   , Desjardins Kelly
Published: February 2025

Given the diversity found in today's Japanese culture and the size of the country's population, it is easy to see why the understanding of Japanese wind band repertoire must be multi-faceted. Alongside Western elements, many Japanese composers have intentionally sought to maintain their cultural identity through the addition of Japanese musical elements or concepts. These added elements provide a historical and cultural context from which to frame a composition or, in some cases, a composer's compositional output. The employment of these elements serve as a means to categorize the Japanese wind band repertoire. In his studies on cultural identities found in Japanese music, Gordon Matthews suggests there are three genres found within Japanese culture. He explains these as "senses of 'Japaneseness' among Japanese musicians." They include Fence, Flavor, and Phantasm. Bringing a new perspective to the idea of Japanese influence, I trace the implementation of these facets of Japanese music through the wind band music of Japanese composers. I demonstrate that Japanese wind band genres are the result of a combination of Japanese musical elements and Western influence and argue that the varying levels of this combination, balanced with historical and cultural context, create three distinct genres within the Japanese wind band repertoire.
Resilience of Microgrid during Catastrophic Events
Authors:   , Black Travis Glenn
Published: February 2025

Today, there is a growing number of buildings in a neighborhood and business parks that are utilizing renewable energy generation, to reduce their electric bill and carbon footprint. The most current way of implementing a renewable energy generation is to use solar panels or a windmill to generate power; then use a charge controller connected to a battery bank to store power. Once stored, the user can then access a clean source of power from these batteries instead of the main power grid. This type of power structure is utilizing a single module system in respect of one building. As the industry of renewable power generation continues to increase, we start to see a new way of implementing the infrastructure of the power system. Instead of having just individual buildings generating power, storing power, using power, and selling power there is a fifth step that can be added, sharing power. The idea of multiple buildings connected to each other to share power has been named a microgrid by the power community. With this ability to share power in a microgrid system, a catastrophic event which cause shutdowns of power production can be better managed. This paper then discusses the data from simulations and a built physical model of a resilient microgrid utilizing these principles.

The primary aim of this research is to answer how health education information is accepted and interpreted based on cultural definitions of diabetes to inform diabetes management strategies.
Hybrid Approaches in Test Suite Prioritization
Authors:   , Nurmuradov Dmitriy
Published: February 2025

The rapid advancement of web and mobile application technologies has recently posed numerous challenges to the Software Engineering community, including how to cost-effectively test applications that have complex event spaces. Many software testing techniques attempt to cost-effectively improve the quality of such software. This dissertation primarily focuses on that of hybrid test suite prioritization. The techniques utilize two or more criteria to perform test suite prioritization as it is often insufficient to use only a single criterion. The dissertation consists of the following contributions: (1) a weighted test suite prioritization technique that employs the distance between criteria as a weighting factor, (2) a coarse-to-fine grained test suite prioritization technique that uses a multilevel approach to increase the granularity of the criteria at each subsequent iteration, (3) the Caret-HM tool for Android user session-based testing that allows testers to record, replay, and create heat maps from user interactions with Android applications via a web browser, and (4) Android user session-based test suite prioritization techniques that utilize heuristics developed from user sessions created by Caret-HM. Each of the chapters empirically evaluate the respective techniques. The proposed techniques generally show improved or equally good performance when compared to the baselines, depending on an application under test. Further, this dissertation provides guidance to testers as it relates to the use of the proposed hybrid techniques.
Examination of Magnetic Plasma Expulsion

Published: February 2025

Magnetic plasma expulsion uses a magnetic field distortion to redirect incident charged particles around a certain area for the purposes of shielding. Computational studies are carried out and for certain values of magnetic field, magnetic plasma expulsion is found to effectively shield a sizable area. There are however many plasma behaviors and interactions that must be considered. Applications to a new cryogenic antimatter trap design are discussed.
Implementation of Compressive Sampling for Wireless Sensor Network Applications
Authors:   , Ruprecht Nathan Alexander
Published: February 2025

One of the challenges of utilizing higher frequencies in the RF spectrum, for any number of applications, is the hardware constraints of analog-to-digital converters (ADCs). Since mid-20th century, we have accepted the Nyquist-Shannon Sampling Theorem in that we need to sample a signal at twice the max frequency component in order to reconstruct it. Compressive Sampling (CS) offers a possible solution of sampling sub-Nyquist and reconstructing using convex programming techniques. There has been significant advancements in CS research and development (more notably since 2004), but still nothing to the advantage of everyday use. Not for lack of theoretical use and mathematical proof, but because of no implementation work. There has been little work on hardware in finding the realistic constraints of a working CS system used for digital signal process (DSP). Any parameters used in a system is usually assumed based on stochastic models, but not optimized towards a specific application. This thesis aims to address a minimal viable platform to implement compressive sensing if applied to a wireless sensor network (WSN), as well as address certain parameters of CS theory to be modified depending on the application.
Conducting from the Piano? A Tradition Worth Reviving?
Authors:   , Marshall Eldred

This thesis aims to utilize data analysis and predictive modeling techniques and apply them in different domains for gaining insights. The topics were chosen keeping the same in mind. Analysis of customer interests is a crucial factor in present marketing trends and hence we worked on twitter data which is a significant part of digital marketing. Neuroscience, especially psychological behavior, is an important research area. We chose eye tracking data based on which we differentiated human concentration while watching controllable (video game) videos and uncontrollable (sports) videos. Currently, cities are using data analysis for becoming smart cities. We worked on the City of Lewisville emergency services data and predicted the vehicle-accident-prone areas for development of precautionary measures in those areas.
Processing-Structure-Property Relationships of Spark Plasma Sintered Boron Carbide and Titanium Diboride Ceramic Composites

The aim of this study was to understand the processing – structure – property relationships in spark plasma sintered (SPS) boron carbide (B4C) and B4C-titanium diboride (TiB2) ceramic composites. SPS allowed for consolidation of both B4C and B4C-TiB2 composites without sintering additives, residual phases, e.g., graphite, and excessive grain growth due to long sintering times. A selection of composite compositions in 20% TiB2 feedstock powder increments from 0% to 100%, was sintered at 1900°C for 25 minutes hold time. A homogeneous B4C-TiB2 composite microstructure was determined with excellent distribution of TiB2 phase, while achieving ~99.5% theoretical density. An optimum B4C-23 vol.% TiB2 composite composition with low density of ~3.0 g/cm3 was determined that exhibited ~30-35% increase in hardness, fracture toughness, and flexural bend strength compared to commercial armor-grade B4C. This is a result of a) no residual graphitic carbon in the composites, b) interfacial microcrack toughening due to thermal expansion coefficient differences placing the B4C matrix in compression and TiB2 phase in tension, and c) TiB2 phase aids in crack deflection thereby increasing the amount of intergranular fracture. Collectively, the addition of TiB2 serves as a strengthening and toughening agent, and SPS shows promise for the manufacture of hybrid ceramic composites.
Students' Perceptions on the Impact of Teacher Expectation Bias on Classroom College Readiness Opportunities
Authors:   , Wellman Kristen Suzanne
Published: February 2025

As increasing emphasis is being placed on student college and career readiness, instructional approaches seek to develop content and skill proficiency. I gathered student perspectives on teacher expectations and instructional opportunities in core content classes in order to determine if expectation bias influences college readiness preparation in the classroom. Student academic self-concept and college readiness were examined alongside beliefs about teacher expectations and instructional opportunities in a conceptual framework for student perceptions. In this qualitative study, I utilized four focus groups of high school students from two cohorts to analyze perceptions across students from mostly on-level core classes and those from mostly advanced core classes. Findings showed students held high expectations of their own current and future performance, as well as perceived teachers generally hold high expectations, though this was shown through the development of relational capacity rather than instructional opportunities to develop college readiness skills or connect to students' future ambitions. The results of the study provide insight to educators seeking to create stronger connections for students between current educational experiences and future postsecondary opportunities.
Electrodeposition of Molybdenum-Based Coatings from Aqueous Alkaline Solutions for Enhanced Corrosion Resistance
Authors:   , Zhou Ting
Published: February 2025

Zn-Mo coatings are very promising environment friendly anticorrosive coatings as replacement materials for cadmium and chromium (VI) based conversion layers. Electrodeposition has become a favorable technique in fabricating coatings due to its low cost, ease of use, and overall experimental control of coating quality. Very little research so far has been done for the electrodeposition of Zn-Mo coatings under alkaline conditions. In this work, Zn and Zn-Mo coatings were electrochemically deposited on stainless steel from an aqueous alkaline citrate solution. An organic compound, vanillin, was added to the electrolyte as a leveling agent for improving interlayer adherence and corrosion resistance of Zn-Mo coatings. Ni-Mo alloys have been known to possess high tensile strength and excellent corrosion protection of steels, and MoTe2 layers have a potential for the application in anticorrosive coatings due to their hydrophobic properties. In this study, MoTe2-Ni-Mo coatings were deposited on stainless steel using both sputtering and electrodeposition methods. These coatings with high corrosion resistance and other desirable properties are in demand in the oil and gas industry since they can protect and thus extend the lifetime of the underlying materials when exposed to aggressive environments. The Zn-Mo and MoTe2-Ni-Mo coatings were evaluated for chemical composition and corrosion behavior using different types of instrumental and electrochemical techniques. The addition of vanillin to the electrolyte did not change the crystalline structure or composition of the Zn-Mo coating, however, the corrosion resistance of the coating was significantly improved by the leveling effect of vanillin during the electrodeposition. The corrosion resistance of the Ni-Mo coating was also enhanced by applying the hydrophobic MoTe2 monolayer on the top surface.
