Improving Software Quality through Syntax and Semantics Verification of Requirements Models
Authors:   , Gaither Danielle
Published: February 2025

Software defects can frequently be traced to poorly-specified requirements. Many software teams manage their requirements using tools such as checklists and databases, which lack a formal semantic mapping to system behavior. Such a mapping can be especially helpful for safety-critical systems. Another limitation of many requirements analysis methods is that much of the analysis must still be done manually. We propose techniques that automate portions of the requirements analysis process, as well as clarify the syntax and semantics of requirements models using a variety of methods, including machine learning tools and our own tool, VeriCCM. The machine learning tools used help us identify potential model elements and verify their correctness. VeriCCM, a formalized extension of the causal component model (CCM), uses formal methods to ensure that requirements are well-formed, as well as providing the beginnings of a full formal semantics. We also explore the use of statecharts to identify potential abnormal behaviors from a given set of requirements. At each stage, we perform empirical studies to evaluate the effectiveness of our proposed approaches.
Information Seeking in a Balkan Country: A Case Study of College Students Seeking and Use of Information
Authors:   , Kabashi Artemida
Published: February 2025

Using a case study approach this study investigated how college students in Vlore, Albania seek and use information resources for academic and personal needs and whether they follow a pattern similar to Brenda Dervin's sense-making, or Marcia Bates' berry-picking information seeking models. Influencing factors studied were economic factors, information communication technologies and information culture/policy. A literature review showed that no previous published research has studied information seeking behavior of college age students and faculty in Albania. Thirty-four college students and two full time faculty completed a survey and a smaller group were interviewed. The results of the study indicate that Google is the main source for seeking information for both academic and personal purposes. College students are not introduced or taught on how to evaluate information sources. The information communication technology needs improvement to support information needs. The library as a major information resource was not apparent to most students. College students utilize berry-picking as the information seeking model and faculty use sense-making, as a model of information seeking. This study adds to the knowledge of the information seeking behavior of college students in a developing country, the need for information literacy courses at the university level, and the identification of additional areas of research regarding information communication technologies, information policy, and literacy for developing countries.
Exploring Growth Kinematics and Tuning Optical and Electronic Properties of Indium Antimonide Nanowires
Authors:   , Algarni Zaina Sluman
Published: February 2025

This dissertation work is a study of the growth kinematics, synthesis strategies and intrinsic properties of InSb nanowires (NWs). The highlights of this work include a study of the effect of the growth parameters on the composition and crystallinity of NWs. A change in the temperature ramp-up rate as the substrate was heated to reach the NW growth temperature resulted in NWs that were either crystalline or amorphous. The as-grown NWs were found to have very different optical and electrical properties. The growth mechanism for crystalline NWs is the standard vapor-liquid-solid growth mechanism. This work proposes two possible growth mechanisms for amorphous NWs. The amorphous InSb NWs were found to be very sensitive to laser radiation and to heat treatment. Raman spectroscopy measurements on these NWs showed that intense laser light induced localized crystallization, most likely due to radiation induced annealing of defects in the region hit by the laser beam. Electron transport measurements revealed non-linear current-voltage characteristics that could not be explained by a Schottky diode behavior. Analysis of the experimental data showed that electrical conduction in this material is governed by space charge limited current (SCLC) in the high bias-field region and by Ohm's law in the low bias region. Temperature dependent conductivity measurements on these NWs revealed that conduction follows Mott variable range hopping mechanism at low temperatures and near neighbor hopping mechanism at high temperature. Low-temperature annealing of the amorphous NWs in an inert environment was found to induce a phase transformation of the NWs, causing their crystallinity to be enhanced. This thesis also proposes a new and low-cost strategy to grow p-type InSb NWs on InSb films grown on glass substrate. The high quality polycrystalline InSb film was used as the host on which the NWs were grown. The NWs with an average diameter of 150 nm and length of 20 μm were shown to have hole concentration of about 1017 cm-3 and mobility of about 1000 cm2V-1s-1. This thesis also proposes a strategy for the fabrication of metal-semiconductor nanocomposites. InSb NWs grown by electrochemical deposition were decorated with nanometer sized Au and Ag nanoparticles to form the nanocomposite.
Demand and Supply Explanation: Nonprofit Size in Homeless Service Area
Authors:   , Kilic Gorunmek Hediye
Published: February 2025

This study explores the demand and supply oriented factors that may contribute to the size of nonprofit organizations in the U.S. communities. This research tests demand theory, which indicated that nonprofit organizations grow more in communities where large service demand exists and when there is a service gap between community demand and government service supply. On the other hand, supply theories contend that nonprofit organizations are prevalent where a community carries the supply of human capital and financial resources and these supply of human and economic capital will mobilize nonprofit organizations to fulfill civic duties. For the scientific test of demand and supply theories, this study employs hierarchical linear model (HLM) and develops a longitudinal data set from multiple sources such as Department of Housing and Urban Development and National Charitable Center for Statistics, and Census. The proposed model analyzes how demand and supply indicators explain homeless serving nonprofit organizations size. The size of homeless service nonprofit was measured by three indicators: number of nonprofits, revenue of nonprofits and number of shelter beds. The findings of HLM analyses confirmed some of demand and supply factors that contribute homeless service nonprofit size. The communities with higher level of chronic homeless population have more nonprofit organizations when we control community size. Also, we found the communities with a greater number of educated individuals are more likely to invest in nonprofit organizations. And it was noteworthy that the higher education institution was a positive supply factor for the nonprofit size in our communities.
Elementary Students' Perceptions of Their Authentic Engagement when Using iPads in the Classroom
Authors:   , Hayunga Kelly Lynn
Published: February 2025

The purpose of this study was to examine the impact of a 1:1 iPad initiative on student engagement in the classroom, as perceived by students. The design of this case study consisted of a purposeful sample of six, 5th grade students from a suburban elementary school in North Central Texas who participated in surveys, individual interviews, and focus group discussions. Two research questions guided this study: (1) How do elementary school students perceive they are authentically engaged when using iPads in the classroom? (2) What types of instructional strategies do elementary school students perceive to be most relevant and meaningful? Data collected to answer the research questions was analyzed using thematic analysis, which entailed identifying recurring themes within the data, comparing, coding, combining, and then reporting them. The findings from the research suggested that 1:1 initiatives can foster engaging learning experiences that are meaningful to students and that the iPad provided students a more personalized learning experience which had a positive effect on their engagement. Additional findings disclosed that the type of assignments and schoolwork that students were able to do with the iPad also positively impacted their engagement and interest in the content and their learning. The conclusions reached in this study also supported findings from other studies on 1:1 programs and student engagement.
Compartmentalization of Jojoba Seed Lipid Metabolites
Authors:   , Sturtevant Drew
Published: February 2025

Seeds from the desert shrub Simmondsia chinensis (jojoba) are one of the only known natural plant sources to store a majority of its oil in the form of liquid wax esters (WE) instead of triacylglycerols (TAGs) and these oils account for ~55% of the seed weight. Jojoba oil is highly valued as cosmetic additives and mechanical lubricants, yet despite its value much is still unknown about its neutral lipid biosynthetic pathways and lipid droplet packaging machinery. Here, we have used a multi-"omics" approach to study how spatial differences in lipid metabolites, gene expression, and lipid droplet proteins influence the synthesis and storage of jojoba lipids. Through these studies mass spectrometry analyses revealed that WEs are compartmentalized primarily in the cotyledonary tissues, whereas TAGs are, surprisingly, localized to the embryonic axis tissues. To study the differences in gene expression between these two tissues, a de novo transcriptome was assembled from high throughput RNAseq data. Differential gene expression analysis revealed that the Jojoba Wax Synthase, which catalyzes the formation of wax esters, and the Diacylglycerol O-Acyltransferase1, which catalyzes the final acylation of triacylglycerol synthesis, were differentially expressed in the cotyledons and embryonic axis tissues, respectively. Furthermore, through proteomic analysis of lipid droplet proteins from lipid droplets of the cotyledons and embryonic axis, it was estimated that each of these tissues contains a different proportion of the major lipid droplet proteins, oleosins, steroleosins, caleosins, and lipid droplet associated proteins. The Jojoba Olesosin1, Lipid Droplet Associated Protein 1, and Lipid Droplet Associated Protein 3, were identified as potential lipid droplet proteins that could be important for storage of wax esters. The coding sequences of these genes were transiently expressed in N. benthamiana leaves individually, and with co-expression of Mus musculus diacylglycerol acyltransferase 2, and in all cases were able to induce neutral lipid accumulation. These data also suggest a Lipid Droplet Associated Protein 1 has a specialized role for wax ester accumulation in the cotyledons, whereas Lipid Droplet Associated Protein 3 may have a more generalized role for the storage of triacylglycerols. These differences in compartmentation suggests that the cotyledons and embryonic axis of jojoba have evolved tissue-specific sets of genes for neutral lipid assembly and lipid droplet accumulation. It may be important to consider this tissue context for genetic engineering strategies designed to introduce genes from jojoba into other oilseed crops.
Ontology Based Security Threat Assessment and Mitigation for Cloud Systems
Authors:   , Kamongi Patrick
Published: February 2025

A malicious actor often relies on security vulnerabilities of IT systems to launch a cyber attack. Most cloud services are supported by an orchestration of large and complex systems which are prone to vulnerabilities, making threat assessment very challenging. In this research, I developed formal and practical ontology-based techniques that enable automated evaluation of a cloud system's security threats. I use an architecture for threat assessment of cloud systems that leverages a dynamically generated ontology knowledge base. I created an ontology model and represented the components of a cloud system. These ontologies are designed for a set of domains that covers some cloud's aspects and information technology products' cyber threat data. The inputs to our architecture are the configurations of cloud assets and components specification (which encompass the desired assessment procedures) and the outputs are actionable threat assessment results. The focus of this work is on ways of enumerating, assessing, and mitigating emerging cyber security threats. A research toolkit system has been developed to evaluate our architecture. We expect our techniques to be leveraged by any cloud provider or consumer in closing the gap of identifying and remediating known or impending security threats facing their cloud's assets.
Radically Early College Entrants on Radically Early College Entrance: A Heuristic Exploration
Authors:   , Jett Noel
Published: February 2025

Despite the fact acceleration has been studied thoroughly as an educational practice for the gifted, early entrance to college specifically has been overlooked. Not only this, but a large portion of this research pertains to early college entrance programs, which provide resources that many early college entrants may not have. The lived experiences and perceptions of radically early college entrants (three or more years advanced) were explored through interviews and heuristic inquiry. The interviews addressed affective aspects of early college foremost, with additional discussion of academic experiences, college choice, and career outcomes. Findings support that radically early college entrants are happy with their choice overall, though more specific findings elaborate on the benefits and limitations of early college, possible regrets, and the social issues this population faces.
Child-Centered Play Therapists' Experiences Delivering Shortened Session Lengths
Authors:   , Edwards Joshua Michael
Published: February 2025

This phenomenological study examined the experiences and perceptions of child-centered play therapists who deliver shortened sessions in the clinic setting. Using the phenomenological analysis procedures based on Moustakas' modified Stevick-Colaizzi-Keen method, a coding team of three doctoral students found 10 themes related to child-centered play therapists' (N = 5) experiences delivering shortened session lengths. Each theme is defined and further described using verbatim transcript examples. This study has practical and clinical implications for child-centered play therapist development and training. The results of this study point to the need for further research in child-centered play therapists' experiences delivering play therapy-as-usual. Finally, future research regarding the change process in child-centered play therapy theory is also implicated.
A Conductor's Guide to Hyo-Won Woo's Choral Music as Reflected in "Oh! KOREA"
Authors:   , Noh Wonil
Published: February 2025

The choral music of Hyo-won Woo, the composer of Oh! KOREA, is being widely performed by universities and professional choruses in Korea, as well as throughout the world. The work exhibits Woo's remarkable compositional style, which displays traditional Korean musical influences. Hyo-Won Woo's Oh! KOREA consisting of four movements, is for chorus, two pianos, and both Eastern and Western percussion instruments. Woo's Oh! KOREA employs an excellent introduction to the Korean choral repertoire for Western audiences, rooted in traditional Korean folk tunes. As today's choral conductors, singers, and audience cannot fully appreciate the value of this traditional Korean work and will likely not understand its intended context, it is therefore necessary to provide an in-depth investigation of this work for any conductor considering a performance of this piece. This study includes influences of traditional Korean elements within Oh! KOREA and rehearsal and performance consideration for Western choir directors.
Kaikhosru Sorabji's Rapsodie Espagnole de Maurice Ravel, Transcription de Concert pour piano: A Comparison of the Two Versions from 1923 and 1945
Authors:   , Chu Fang-Yi
Published: February 2025

Kaikhosru Shapurji Sorabji (1892-1988) was an English composer-pianist of Parsi descent. Although he composed many works for piano, these compositions remain largely unknown to the public due to the composer's self-imposed 40-year ban on public performances of all his works and the immense technical difficulty of his music. This research proposes a comparative study of Sorabji's two versions of Rapsodie espagnole de Maurice Ravel-Transcription de concert pour piano (1923, 1945). These transcriptions are based on Ravel's orchestral work and are different in terms of the style of their arrangements: the 1923 version is more of a literal transcription, whereas the 1945 version has been expanded upon the former. This dissertation compares the differences between the two versions, as well as identifying how Sorabji infused his own style into the 1945 transcription. This study relies on primary sources including writings and manuscripts of Sorabji, and secondary sources such as articles on interpreting Sorabji's piano works and biographies about Sorabji.
Lollardy and Eschatology: English Literature c. 1380-1430
Authors:   , Regetz Timothy
Published: February 2025

In this dissertation, I examine the various ways in which medieval authors used the term "lollard" to mean something other than "Wycliffite." In the case of William Langland's Piers Plowman, I trace the usage of the lollard-trope through the C-text and link it to Langland's dependence on the Parable of the Wheat and the Tares. Regarding Chaucer's Parson's Tale, I establish the orthodoxy of the tale's speaker by comparing his tale to contemporaneous texts of varying orthodoxy, and I link the Parson's being referred to as a "lollard" to the eschatological message of his tale. In the chapter on The Book of Margery Kempe, I examine that the overemphasis on Margery's potential Wycliffism causes everyone in The Book to overlook her heretical views on universal salvation. Finally, in comparing some of John Lydgate's minor poems with the macaronic sermons of Oxford, MS Bodley 649, I establish the orthodox character of late-medieval English anti-Wycliffism that these disparate works share. In all, this dissertation points up the eschatological character of the lollard-trope and looks at the various ends to which medieval authors deployed it.
Effects of Transition Metal Oxide and Mixed-Network Formers on Structure and Properties of Borosilicate Glasses
Authors:   , Lu Xiaonan
Published: February 2025

First, the effect of transition metal oxide (e.g., V2O5, Co2O3, etc.) on the physical properties (e.g., density, glass transition temperature (Tg), optical properties and mechanical properties) and chemical durability of a simplified borosilicate nuclear waste glass was investigated. Adding V2O5 in borosilicate nuclear waste glasses decreases the Tg, while increasing the fracture toughness and chemical durability, which benefit the future formulation of nuclear waste glasses. Second, structural study of ZrO2/SiO2 substitution in silicate/borosilicate glasses was systematically conducted by molecular dynamics (MD) simulation and the quantitative structure-property relationships (QSPR) analysis to correlate structural features with measured properties. Third, for bioactive glass formulation, mixed-network former effect of B2O3 and SiO2 on the structure, as well as the physical properties and bioactivity were studied by both experiments and MD simulation. B2O3/SiO2 substitution of 45S5 and 55S5 bioactive glasses increases the glass network connectivity, correlating well with the reduction of bioactivity tested in vitro. Lastly, the effect of optical dopants on the optimum analytical performance on atom probe tomography (APT) analysis of borosilicate glasses was explored. It was found that optical doping could be an effective way to improve data quality for APT analysis with a green laser assisted system, while laser spot size is found to be critical for optimum performance. The combined experimental and simulation approach adopted in this dissertation led to a deeper understanding of complex borosilicate glass structures and structural origins of various properties.
Roles of Primary Cilia in the Oligodendrocyte Lineage
Authors:   , Subedi Ashok
Published: February 2025

Primary cilia are nonmotile, hair-shaped organelles that extend from the basal body in the centrosome. The present study is the first investigation of this organelle in the oligodendrocyte lineage in vivo. I used immunohistochemical approaches in normal and cilia-deficient mutant mice to study cilia in relation to oligodendrogenesis and myelination. Primary cilia immunoreactive for Arl13b and ACIII were commonly present in NG2+ oligodendrocyte progenitor cells (OPCs), in which cilia-associated pathways control proliferation, differentiation, and migration. The loss of primary cilia is generally associated with enhanced Wnt/β-catenin signaling, and Wnt/β-catenin signaling has been shown to promote myelin gene expression. I examined whether the lack of cilia in the oligodendrocyte lineage is associated with elevated Wnt/β-catenin activity. I found that absence of a primary cilium was associated with with higher levels of TCF3, and with β-galactosidase in Axin2-lacZ Wnt reporter mice. This evidence supports the proposal that cilia loss in oligodendrocytes leads to enhanced Wnt/β-catenin activity, which promotes myelination. Cilia are dependent on the centrosome, which assembles microtubules for the cilium, the cytoskeleton, and the mitotic spindle. Centrosomes are the organizing center for microtubule assembly in OPCs, but this function is decentralized in oligodendrocytes. I found that the intensity of centrosomal pericentrin was reduced in oligodendrocytes relative to OPCs, and γ-tubulin was evident in centrosomes of OPCs but not in mature oligodendrocytes. These decreases in centrosomal proteins might contribute to functional differences between OPCs and oligodendrocytes. The importance of cilia in the oligodendrocyte lineage was examined in Tg737orpk mice, which have a hypomorphic IFT88 mutation resulting in decreased cilia numbers and lengths. These mice showed marked, differential decreases in numbers of oligodendrocytes and myelin, yet little or no change in OPC populations. It appears that sufficient cells were available for maturation, but lineage progression was stalled. There were no evident effects of the mutation on Wnt/β-catenin. Factors that might contribute to the abnormalities in the oligodendrocyte lineage of Tg737orpk mice include decreased cilia-dependent Shh mitogenic signaling and dysregulation in cilia-associated pathways such as Notch and Wnt/β-catenin.
A Control Theoretic Approach for Resilient Network Services
Authors:   , Vempati Jagannadh Ambareesh
Published: February 2025

Resilient networks have the ability to provide the desired level of service, despite challenges such as malicious attacks and misconﬁgurations. The primary goal of this dissertation is to be able to provide uninterrupted network services in the face of an attack or any failures. This dissertation attempts to apply control system theory techniques with a focus on system identiﬁcation and closed-loop feedback control. It explores the benefits of system identification technique in designing and validating the model for the complex and dynamic networks. Further, this dissertation focuses on designing robust feedback control mechanisms that are both scalable and eﬀective in real-time. It focuses on employing dynamic and predictive control approaches to reduce the impact of an attack on network services. The closed-loop feedback control mechanisms tackle this issue by degrading the network services gracefully to an acceptable level and then stabilizing the network in real-time (less than 50 seconds). Employing these feedback mechanisms also provide the ability to automatically conﬁgure the settings such that the QoS metrics of the network is consistent with those speciﬁed in the service level agreements.

Does the Method of Financing Stock Repurchases Matter? Examining the Financing of Share Buybacks and Its Effect on Future Firm Investments and Value
Authors:   , Peabody Stephen Drew
Published: February 2025

Recent increases in stock repurchases among U.S. corporations coupled with a historically low cost of debt since the Global Financial Crisis has created media speculation that firms in recent years are paying for their expanding share buyback programs with debt. Repurchasing stock by increasing leverage, instead of using internal funds, implies that managers may speculate on current low interest rate environments at the expense of shareholders. Recent studies find that stock repurchases are associated with reductions in future firm employment and investments such as capital expenditures and research and development expenses. This study expands on prior studies by evaluating how debt-financed stock repurchases affect firm investment, investigating the likelihood of these repurchases in low interest rate environments and assessing the effects on firm value. Results confirm that, in recent years, debt-financed repurchases have increased substantially and the probability of debt-financed repurchases increases in the presence of low interest rates. This relationship is especially pronounced in the years following the Global Financial Crisis. Debt-financed repurchases are associated with small reductions in firm investment; however, these reductions are significantly less after adjusting for industry conditions. Finally, there is little evidence that the method of financing repurchases affects firm value nor does it increase a firm's operating performance.
Building Relationships between a Free Clinic and Its Donors
Authors:   , Nalin Emma R
Published: February 2025

This thesis presents qualitative research conducted in summer 2017 at the Finger Lakes Free Clinic, which provides free medical and holistic care to people without insurance in upstate New York. The primary goal of this research was to strengthen the relationship between a free clinic and its donors by gathering donor concerns and perceptions regarding federal healthcare policy. Data from 32 interviews with donors, staff, board members, and volunteers, along with 100 hours of participant observation revealed that donors to this clinic were concerned about the potential impact of Congressional healthcare reform yet did not consider federal policy a strong influence on their donations. Rather, donors cited dedication to local giving and personal connections with the clinic as their primary motivations. These motivations suggest the value of viewing the clinic-donor relationship as a relationship of reciprocity. From this framework, the research identifies opportunities for the clinic to reciprocate donor generosity while expanding services in response to a growing need. Insights from the research will guide the clinic's response to federal policy changes and support the clinic's vision of becoming a national model for integrative care.
Use of Digital Fabrication Tools and Curriculum with Gifted Students in Rural Middle Schools
Authors:   , Moore Vince
Published: February 2025

This study focuses on the use of American Invention Kits from the Smithsonian Institute in conjunction with a 3D printer. In conjunction with a large dataset from a study funded by the National Science Foundation (NSF), this innovative research focuses on the effect the digital fabrication curriculum unit has on gifted and talented students' knowledge and affinity toward the fields of science, technology, engineering, and mathematics (STEM). Students from two rural middle schools in north-central Texas (N = 190) took part in this quantitative study; the students were divided among four subgroups: gifted-contrast (n = 12), gifted-treatment (n = 8), nongifted-contrast (n = 76), and nongifted-treatment (n = 94). The surveys utilized include the STEM Semantics Survey, TIMSS-Limited, and a knowledge assessment for the specific curriculum unit focused on the solenoid. The STEM Semantics Survey is divided into five subsets. Thirty-two separate one-way repeated measures ANOVAs were performed across the surveys and subgroups. Statistically significant results were found on four comparisons. This research holds implications in the areas of advocating for gifted education, collecting field data, utilizing large datasets, and understanding rural schools.
Investigation, Interpretation and Internalization in Concerto Piccolino for Vibraphone by Milton Babbitt
Authors:   , Yakas James
Published: February 2025

Written in 1999, Concerto Piccolino is a part of the Composer's Guild of New Jersey Vibraphone Commission, which contains a collection of twelve soli written exclusively for vibraphone. Concerto Piccolino presents vibrant opportunities for both performer and listener to experience the compositional world of Milton Babbitt. With its limited register, ability to control duration and create extreme dynamics, the vibraphone serves as an appropriate vehicle for Babbitt's multi-dimensional style. The intent of this study is to first situate this work into Babbitt's compositional output as well as referencing Babbitt's other works for solo percussion. Next, an investigation into the background structure will provide a recommended analytical framework. Included is a performance guide for how these structures should be realized via surface materials throughout the interpretive and internalization stages of the work. Examining a recommended progression from analysis through performance will demonstrate Concerto Piccolino's significance and proper place in the standard repertoire of percussion. The study concludes with discussing connections to pedagogy and how the importance of Babbitt's work, as well as other composers of serious music, is vital to the forward progress of music performance.
William's America: Royal Perspective and Centralization of the English Atlantic
Authors:   , Woodlock Kylie Michelle
Published: February 2025

William III, Prince of Orange, ascended the throne of England after the English Glorious Revolution of 1688. The next year, the American colonists rebelled against colonial administrations in the name of their new king. This thesis examines William's perception of these rebellions and the impact his perception had on colonial structures following the Glorious Revolution. Identifying William's modus operandi—his habit of acceding to other's political choices for expediency until decisive action could be taken to assert his true agenda—elucidates his imperial ambitions through the context of his actions. William, an enigmatic and taciturn figure, rarely spoke his mind and therefore his actions must speak for him. By first establishing his pattern of behavior during his early career in the Netherlands and England, this project analyzes William's long-term ambitions to bring the Americas under his direct control following the 1689 rebellions and establish colonial administrations more in line with his vision of a centralized English empire.
Critique, Hope, and Action: A Critical Content Analysis of Teacher-Selected Literature for the Elementary Classroom
Authors:   , Edwards Jessica Lee Lavina
Published: February 2025

The purpose of this study was to analyze teacher-selected children's literature for its potential use with critical pedagogy in the elementary classroom. This multi-analytical study uses tenets from critical multicultural analysis (CMA) and components from visual analysis (VA) to guide a critical content analysis of teacher-selected children's literature. Since it is the only nationally-recognized book list solely selected by educators, the texts for this study were selected from the Teachers' Choices Reading List titles. Although prior research on teacher-selected literature for the potential use of critical pedagogy in the elementary classroom does not exist, the results of this study show many opportunities for such within the last three years of the Teachers' Choices Reading List. A discussion on these results is presented through Paulo Freire's concept of critical pedagogy, as described in three stages: critique, hope, and action. Implications for practice and research are suggested based on the results of the study.
Chronic Homelessness and the Aging Population: Findings in a Homeless Sample from Arkansas
Authors:   , Chekuri Lakshminarayana
Published: February 2025

Understanding underlying mechanisms and pathways that lead to chronic homelessness would help develop intervention strategies that could help prevent subsequent episodes of homelessness. Quantitative data for this cross-sectional study was gathered by interviewing individuals who were homeless in the State of Arkansas, using a structured survey between 2007 and 2011. Qualitative data was gathered using semi-structured interviews between 2016 and 2018. Chi-square statistics and a multivariate logistic regression model was used to analyze the quantitative data, while phenomenological methods were used to analyze the qualitative data. Nearly half of the study participants identified themselves as being chronically homeless. Chronically homeless adults in this region were significantly more likely to be older men with no family ties, more likely to be victims of domestic violence, have higher rates of physical health problems, and have alcohol and substance abuse problems. Results from the multivariate nominal regression revealed that individuals who reported themselves as chronically homeless were more likely to be in the 50 years or older age group. In addition, study findings highlighted a dynamic interplay between three biopsychosocial risk factors for homelessness. Fostering development of inclusive sustainable communities, intergenerational relationships, and shared housing practices could help ease such social inequities and prevent problems such as chronic homelessness in older homeless adults.
Design Principles for Metal-Coordinated Frameworks as Electrocatalysts for Energy Storage and Conversion
Authors:   , Lin Chun-Yu
Published: February 2025

In this dissertation, density functional theory calculations are performed to calculate the thermodynamic and electrochemical properties of metal coordinated frameworks for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Gibb's free energy, overpotential, charge transfer and ligands effect are evaluated. The charge transfer analysis shows the positive charges on the metal coordinated frameworks play an essential role in improving the electrochemical properties of the metal coordinated frameworks. Based on the calculations, design principles are introduced to rationally design and predict the electrochemical properties of metal coordinated frameworks as efficient catalysts for ORR and OER. An intrinsic descriptor is discovered for the first time, which can be used as a materials parameter for rational design of the metal coordinated frameworks for energy storage and conversion. The success of the design principles provides a better understanding of the mechanism behind ORR and OER and a screening approach for the best catalyst for energy storage and conversion.

We developed this solution using the latest deep learning technique called convolutional neural networks. This system uses blink detection to initiate the recognition process, Convex Hull-based hand segmentation with adaptive skin color filtering to segment hand region, and a convolutional neural network to perform gesture recognition. An ensemble of four convolutional neural networks are trained with a dataset of 25254 images for gesture recognition and a feedback unit called head pose estimation is implemented to validate the correctness of predicted gestures. This entire system was developed using Python programming language and other supporting libraries like OpenCV, Tensor flow and Dlib to perform various image processing and machine learning tasks. This entire application can be deployed as a web application using Flask to make it operating system independent.
Improving Photovoltaic Panel Efficiency by Cooling Water Circulation
Authors:   , Joseph Jyothis
Published: February 2025

This thesis aims to increase photovoltaic (PV) panel power efficiency by employing a cooling system based on water circulation, which represents an improved version of water flow based active cooling systems. Theoretical calculations involved finding the heat produced by the PV panel and the circulation water flow required to remove this heat. A data logger and a cooling system for a test panel of 20W was designed and employed to study the relationship between the PV panel surface temperature and its output power. This logging and cooling system includes an Arduino microcontroller extended with a data logging shield, temperature sensing probes, current sensors, and a DC water pump. Real-time measurements were logged every minute for one or two day periods under various irradiance and air temperature conditions. For these experiments, a load resistance was chosen to operate the test panel at its maximum power point. Results indicate that the cooling system can yield an improvement of 10% in power production. Based on the observations from the test panel experiments, a cooling system was devised for a PV panel array of 640 W equipped with a commercial charge controller. The test data logger was repurposed for this larger system. An identical PV array was left uncooled and monitored simultaneously to compare the effect of cooling, demonstrating that the cooled array provided up to an extra 132W or 20% of maximum power for sunny weather conditions. Future expansion possibilities of the project include automated water level monitoring system and water filtration systems.
Understanding Employability Development Skills through Co-Curricular Activities
Authors:   , Cleveland Rachel
Published: February 2025

Employability skill development is being increasingly investigated among higher education scholars, corporate hiring managers, and governments around the world. Understanding employability skill development is important because it has implications on educational policy, teaching techniques, curriculum designs, and recruitment practices. This study was conducted at a public research university in a southwestern state of the United States. It was designed to understand the difference in employability skill development among students who participated in a leadership development program compared to those who did not. Additionally, the study investigated what skills were seeing the most change among student participated in the leadership development program, and if a student's major of study played any role in their overall employability development over the course of a year. Eight employability skills were tested in a pre- and post-test model. Results indicated that students in leadership development programs are more likely to see an increase in employability skill development. From the skills tested among participates, those in the leadership program found the most change over time in the area of problem solving skills. Finally, the results also indicate that a student's major does have an impact on their overall employability skill development. Students who major in business had significantly higher employability scores than those in other majors at the university.
A Model of Treatment Compliance Behavior of Patients with Chronic Disease in the Age of Predictive Medicine: The Role of Normative Beliefs
Authors:   , Imhonde Benjamin A.
Published: February 2025

The purposes of this study are: a) to understand the treatments compliance behavior of the patient with chronic disease at the behavioral level, particularly, the relationship between treatments compliance behavior and normative beliefs; b) develop a behavioral model of patient's treatments compliance behavior that could be used for predicting, combating, treating, tracking and controlling the treatments compliance behavior of the patients with chronic disease. Seventy-two patients from senior daycare centers in the Dallas area, who suffer or had suffered from at least, one chronic disease, participated in the study. Data gathering was conducted using paper-based questionnaire. The most significant finding of this study is the relationship between normative beliefs and the treatments compliance behavior of the patient with chronic disease. Normative beliefs were found to have significant impact on the treatments compliance intent and behavior of the patients with chronic disease. Another important finding showed that side-effects of prescribed treatments have little or no influence on the treatments compliance behavior of the patient with chronic disease. A relationship between the effectiveness of medicine, particularly, predictive medicine, and treatments compliance behavior was established. The design of the study was intended to provide coverages for a set of constructs that may be the interacting units in the environment of any chronic disease treatments decision. It depicts relational, information communications links between the constructs. The Imhonde model of treatments compliance behavior was designed to include cultural norms and other beliefs that are significant for real-time human ailments decisions behaviors. It is recommended that further studies may include the use of a larger population of participants from diverse cultures and localities in multiple states and countries, with the object of finding the differences that culture and local environments may have on the normative leaning for treatments compliance behavioral decisions in chronic disease cases.
Creative Matter: Exploring the Co-Creative Nature of Things
Authors:   , Hood Emily Jean
Published: February 2025

This dissertation is about new materialism as it relates to art education. It is a speculative inquiry that seeks to illuminate the interconnectivity of things by considering the ways in which things participate in generative practices of perceiving and making. To do so, the dissertation pioneers an arts-based methodology that allows for broad considerations about who and what can be considered an agent in the process of art making. In this inquiry, the researcher is an artist-participant with other more-than-human and human participants to construct an (im)material autohistoria-teoría, a revisionist interdisciplinary artwork inspired by the work of Anzaldúa. The term w/e is developed and discussed as new language for expanding upon Braidotti's posthumanist subjectivity. New theories called thing(k)ing (including found poetry) and (im)materiality are discussed as movements towards better understanding the contributions of the more-than-human in artmaking practices.
Object Recognition Using Scale-Invariant Chordiogram
Authors:   , Tonge Ashwini
Published: February 2025

This thesis describes an approach for object recognition using the chordiogram shape-based descriptor. Global shape representations are highly susceptible to clutter generated due to the background or other irrelevant objects in real-world images. To overcome the problem, we aim to extract precise object shape using superpixel segmentation, perceptual grouping, and connected components. The employed shape descriptor chordiogram is based on geometric relationships of chords generated from the pairs of boundary points of an object. The chordiogram descriptor applies holistic properties of the shape and also proven suitable for object detection and digit recognition mechanisms. Additionally, it is translation invariant and robust to shape deformations. In spite of such excellent properties, chordiogram is not scale-invariant. To this end, we propose scale invariant chordiogram descriptors and intend to achieve a similar performance before and after applying scale invariance. Our experiments show that we achieve similar performance with and without scale invariance for silhouettes and real world object images. We also show experiments at different scales to confirm that we obtain scale invariance for chordiogram.
The Acceptance and Use of Cloud Computing Services by Small and Medium Enterprises in Lagos, Nigeria
Authors:   , Azogu Olajumoke Oluwaseye
Published: February 2025

This study explored the acceptance of cloud computing (CC) services by small and medium enterprises (SMEs) in Lagos, Nigeria, which has been missing from CC services literature. It aimed to understand the motivations for adoption, the uses of the services, and the benefits they derive from it. The uses and gratification theory was applied as the theoretic framework for this endeavor. An online survey with close-ended and open-ended questions was distributed to 1200 randomly selected participants through email. In total, 392 valid responses were collected and analyzed using descriptive statistics and categories. The results found that SMEs in Lagos, Nigeria had a low level of awareness and appreciation of CC services. The adoption rate was also low. Unlike their counterparts in other regions, SMEs primary concerns were service downtime, stable power supply, and better internet access. The study found that SMEs were not taking full advantage of the capabilities of CC services. Some sections, however, were doing better than others, such as the information and communications sub-sector. This study suggested that targeted interventions should be conducted to raise the awareness of CC services in SMEs, and to improve their efficient and effective use of CC services. The uses and gratification theory was appropriate for guiding this study to understand the acceptance and use of CC services by SMEs in Lagos, Nigeria.
A Selected List of Music for Solo Clarinet and Clarinet with Piano by Taiwanese Female Composers Composed between 1986 and 2015: The Investigation of a Neglected Repertory with an Annotated Bibliography
Authors:   , Wang Yi-Wen
Published: February 2025

Clarinet works by Taiwanese female composers are not well researched or catalogued, and to date, and no comprehensive research codifies this subcategory in Taiwan or elsewhere. A comprehensive research and bibliography is necessary to the international community. It is hoped that through this annotated bibliography, readers will gain a deeper understanding of this genre. This study contains a brief history of Taiwan's Western music history, the female composers' history in Taiwan, and literature review. A total of twenty compositions by eighteen different Taiwanese female composers are discussed in the annotated bibliography, including thirteen for unaccompanied clarinet and seven for clarinet and piano. Information includes a brief biography of the composer, the date of composition, duration, premiere, dedication, commission, location of the score, difficulty and commentary on the piece.
Partition Properties for Non-Ordinal Sets under the Axiom of Determinacy
Authors:   , Holshouser Jared
Published: February 2025

In this paper we explore coloring theorems for the reals, its quotients, cardinals, and their combinations. This work is done under the scope of the axiom of determinacy. We also explore generalizations of Mycielski's theorem and show how these can be used to establish coloring theorems. To finish, we discuss the strange realm of long unions.
