A Comprehensive Investigation of Photoinduced Electron Transfer and Charge Transfer Mechanisms in Push-Pull Donor-Acceptor Systems: Implications for Energy Harvesting Applications
Donor-acceptor systems exhibit distinctive attributes rendering them highly promising for the emulation of natural photosynthesis and the efficient capture of solar energy. This dissertation is primarily devoted to the investigation of these unique features within diverse donor-acceptor system typologies, encompassing categories such as closely covalently linked, push-pull, supramolecular, and multi-modular donor- acceptor conjugates. The research encompasses an examination of photosynthetic analogs involving compounds such as chelated azadipyromethene (AzaBODIPY), N,N-dimethylaminophenyl (NND), phenothiazine (PTZ), triphenylamine (TPA), phenothiazine sulfone (PTZSO2), tetracyanobutadiene (TCBD), and expanded tetracyanobutadiene (exTCBD). The strategic configuration of the donor (D), acceptor (A), and spacer elements within these constructs serves to promote intramolecular charge transfer (ICT), which are crucial for efficient charge and electron transfer. The employment of cutting-edge analytical techniques, such as ultrafast transient absorption spectroscopy, is integral to the study. Furthermore, a comprehensive suite of analytical methodologies including steady-state UV-visible absorption spectroscopy, fluorescence and phosphorescence spectroscopies, electrochemical techniques (including cyclic voltammetry and differential pulse voltammetry), spectroelectrochemistry, and density functional theory calculation (DFT), collectively contribute to the comprehensive characterization of push-pull donor-acceptor systems, with a particular emphasis on their potential as highly effective solar energy harvesting application.

The Effect of Developmental Hypoxia on Cardiac Physiology in Three Species: Alligator mississippiensis, Chelydra serpentina, and Danio rerio
In this dissertation, I explored the effects of developmental hypoxia on heart contractility in three separate species of ectotherms: the common snapping turtle (Chelydra serpentina), the American alligator (Alligator mississippiensis), and the zebrafish (Danio rerio). I began with the common snapping turtle and tested whether the utilization of the sarcoplasmic reticulum was altered in response to developmental hypoxia. In the next two chapters, developmental hypoxia of the American alligator was explored studying how the cardiac tissue was affected, specifically in physiological stressors, sarcoplasmic reticulum utilization and sensitivity to pharmacological increases in contractility. The last chapter explored how zebrafish heart contractility was altered in response to chronic hypoxia from egg to adult. Findings from these chapters suggest that while developmental hypoxia did alter cardiac contractility, it did not alter the response of the heart to physiological stressors such as increased heart rate or under hypoxia. Overall, these findings contribute to increasing the current understanding of how developmental hypoxia alters the cardiovascular system but with an emphasis on the cardiac tissue level.

Neural Network Classifiers for Object Detection in Optical and Infrared Images
This thesis presents a series of neural network classifiers for object detection in both optical and infrared images. The focus of this work is on efficient and accurate solutions. The thesis discusses the evolution of the highly efficient and tiny network Binary Classification Vision Transformer (BC-ViT) and how through thoughtful modifications and improvements, the BC-ViT can be utilized for tasks of increasing complexity. Chapter 2 discusses the creation of BC-ViT and its initial use case for underwater image classification of optical images. The BC-ViT is able to complete its task with an accuracy of 99.29\% while being comprised of a mere 15,981 total trainable parameters. Chapter 3, Waste Multi-Class Vision Transformer (WMC-ViT), introduces the usefulness of mindful algorithm design for the realm of multi-class classification on a mutually exclusive dataset. WMC-ViT shows that the task oriented design strategy allowed for a network to achieve an accuracy score of 94.27\% on a five class problem while still maintaining a tiny parameter count of 35,492. The final chapter demonstrates that by utilizing functional blocks of BC-ViT, a simple and effective target detection algorithm for infrared images can be created. The Edge Infrared Vision Transformer (EIR-ViT) showed admirable results with a high IoU …

Memories of Troy in Middle English Verse: A Study of "Sir Gawain and the Green Knight," "Troilus and Criseyde," and the "Troy Book"
This thesis explores the influence of the legend of Troy on Sir Gawain and the Green Knight, Chaucer's Troilus and Criseyde, and Lydgate's Troy Book. This study seeks to understand why medieval English Christians held the pagan myth of Troy in such high regard beyond the common postcolonial critique of Trojan ancestry as a justification for political power. I begin by demonstrating how Vergil's Aeneid presents a new heroic ideal much closer to Christian virtue than Homeric values, Aeneas submitting his will to fate and earning his piety through suffering. I then turn to Sir Gawain and the Green Knight, assessing how Gawain is not only descended from Aeneas but how the major events of his quest echo Aeneas' journey, especially in both heroes' submission of their wills to fate. Next, I reveal how Chaucer's Troilus enacts a platonic ascent from a state of ignorance to a state of truth, but as Troilus' name is also linked to the city of Troy itself, the fate of Troilus becomes the fate of Troy. In this way, Chaucer dramatizes the spiritual ascent of his Trojan ancestors in that they move from sin to salvation as a culture. Finally, I investigate how Lydgate …

Social Exchange Theory in the Context of X (Twitter) and Facebook Social Media Platforms with a Focus on Privacy Concerns among Saudi Students
The current research examines the use of social media and its security settings using the Social Exchange Theory (SET) within a Saudi student environment. This research includes an introduction, literature review, methodology, results, and conclusion with the results section presenting the findings from the three essays. The first essay employs the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology of SET. PRISMA's systematic and exhaustive approach to literature evaluation increases the likelihood of obtaining high-quality, reproducible findings. In the second essay, which focuses on awareness of X's (Twitter) security settings, a quantitative research approach was utilized. A sample of former and current Saudi students (graduate and undergraduate) at the University of North Texas participated in the investigation. This research provides an empirical examination of the use of X (Twitter) and its security features within this community by employing statistical analysis of the data from respondents. Likewise, the same sample of Saudi students from the University of North Texas was used for the third essay in which the use of Facebook's security settings was examined. Having a consistent sample across both studies enables a comparison and a greater understanding of the security awareness and practices of this group across …

Teacher Preparation Programs: A Critical View
Individuals who desire to pursue the teaching profession have two primary paths for preparation: either completing a traditional college-based program or an alternative program. A generic qualitative inquiry methodology was used to explore the perspective of novice teacher participants on how prepared they felt based on the preparation program they participated in. Data gathering was accomplished through a novice teacher survey and seven one-on-one semi-structured interviews. The data from the novice teacher survey revealed that college-based preparation participants felt sufficiently prepared 33% of the time, while the alternative preparation participants felt adequately prepared 59% of the time. College-based preparation participants in the semi-structured interviews reported that observing veteran teachers was invaluable in preparing for the first year of teaching. The alternative certification program participants revealed that teaching was significantly more demanding and that teachers face challenges beyond delivering effective lessons. The alternative preparation program offered an extensive library of lessons and learning modules; however, there was little to no guidance on selecting which lessons and learning modules to review. Participants indicated that improvement in the support provided to the novice teacher during the first year is vital when transitioning from theory to practice. Continued examination of teacher preparation programs is …

"Have You Ever Had a Broken Heart?"
Have You Ever Had Broken Heart? is a collection of essays that interrogate memory, loss, and grief through the intersection of personal narrative, films, the actress Frances Farmer, and woman saints and mystics from the twelfth through seventeenth centuries who were punished for daring to speak to G-d. The essays engage with autotheory and include a myriad of forms, such as segmented, one sentence, and hybrid works. The films discussed range from the philosophical, such as Ingmar Bergman's Winter Light (1963), to Graeme Clifford's biopic, Frances (1982), to catechize the grief of the persona losing her mother and sister to a hit and run car wreck in June 2022. The persona traverses the realm of the mystics and saints, including Marguerite Porete, Sor Juana Inez De La Cruz, and Joan of Arc, examining their respective quests to experience the unseen and often silent divine, while questioning her longing for G-d, and simultaneously believing G-d cannot exist. Yet, within this confusion, she finds herself immersed in memories which carry the presence of her mother's love.

The Politics of F. Scott Fizgerald
F. Scott Fitzgerald is valued for his contribution to literary arts, culture and his discussion of the American Dream. I argue that his discussion of the American Dream was a lens through which he gave readers access to political insights and an education about political philosophy, American politics, virtue, and reasoning. The American Dream, at its greatest, for Fitzgerald is a nation building myth but at its lowest is a dull materialistic construct. Throughout his works Fitzgerald connects philosophic ideas to the American Dream in attempts to educate and ennoble his readers. The ability to judge well is a critical piece of self-government that was a focus of Fitzgerald's throughout his body of work. In The Beautiful and Damned, by giving weight to Platonic ideals of beauty and goodness, and Platonic heuristics like the allegory of the cave he attempted to negate the detrimental effects of nihilism in America at his time and after. In The Great Gatsby, by presenting virtue of the contemplative life that could be cultivated by his readers, in his time, and including esoteric teachings on those virtues and values he attempted to negate the detrimental effects of materialism on the American dream. Finally, in The …

An Empirical Investigation of the Medical Supply Chain and Its Impact on Human Solid Organ Transplantation
The objective of this dissertation is to first identify if there are any academic research gaps in our understanding of the medical supply chain and secondly to understand the role and impact of logistics on the human organ transplant process. The first essay identifies the current status of medical supply chain literature and provides future direction for improving the medical supply chain. This was accomplished by preforming a systematic literature review and a bibliometric analysis from 2,160 publications was conducted. The second essay explores how logistical aspects impact transplant logistics performance and the quality of life for the transplant recipient. Survey data was collected from medical professionals and analyzed using structural equation modeling. The third essay identifies the factors are influencing the number of donor kidneys discarded each year. A retrospective analysis of all deceased donor kidneys procured in hospitals in UNOS region 4 (Texas and Oklahoma) from January 1, 2001, to June 28, 2021, was conducted. Data was analyzed using multinomial logit regression and panel data analysis. As a result, we identified several medical and logistics factors that have influenced the number of donor kidneys discarded in the United States.

Needs Analysis for the Implementation of Supplemental Educational Videos in the Training of Surgical Residents
This dissertation aimed to research the possibility of integrating a supplemental video system in a surgical residency for educational use. A needs analysis was to be conducted in order to find if current stakeholders would accept such a system within a surgical residency: (a) surgical residents, (b) teaching physicians, and (c) administrators. The study aimed to research factors that complicate the current educational setting for surgical residents, such as time allotted for learning, fatigue during learning opportunities, teaching physicians time and effort into teaching responsibilities, and the cost of such systems and their perceived value to administrators. Also investigated was the type of learning theories best suited to creating a supplemental video system in a hospital setting. After this, a set of interviews was conducted amongst the stakeholders to evaluate the needs of the residency and the willingness of all parties to accept the system into their educational structure. What was found was a high level of interest in a more centralized learning management system, which is the central depository for all educational materials to be used by the residents. Most agreed that the learning environment lacked structure and optimally required something more substantial than adding supplemental videos to the …

An Evaluation of the Utility of Fixed Ratio 1 Schedule Contingent Reinforcement on Variability to Increase the Diversity of Activity Selections and the Treatment of Problem Behavior Occasioned by Interruption Routines
Adults with autism spectrum disorder (ASD) and intellectual disability (ID) are the majority of population in residential settings. Many clients in residential settings engage in problem behavior that interferes with their daily routine and work requirements. Restricted and repetitive behavior are one of the features of ASD diagnosis, typically in the form of invariable responding and predictable responses. Differential reinforcement has been used to produce and maintain response variability. I evaluated the utility of a fixed ratio 1 (FR1) schedule on variability to increase the diversity of activity selections in the treatment of problem behavior occasioned by the interruption of routines. Chase engaged in problem behaviors in his bathroom routine, no matter by himself or with his housemate. Results demonstrated a reinforcement-based treatment increased both variable and novel selections while decreasing the rate of self injurious behavior.

Nitrogen Reduction Reaction: Deposition, Characterization and Selectivity of Transition Metal (V, Co and Ti) Oxynitrides as Electrocatalysts
The electrocatalytic nitrogen reduction reaction (NRR) is of considerable interest due to its potential for less energy intensive and environmentally friendly ammonia production which is critical for agricultural and clean energy applications. However, the selectivity of NRR compared to the hydrogen evolution reaction (HER) often poses challenges for various catalysts, including Earth-abundant transition metal oxynitrides like Ti, V, and Co. In this work, a comparative analysis of the selectivity of these three metal oxynitrides was conducted, each having different metal oxophilicities. A combination of electrochemical, surface characterizations and density functional theory (DFT) calculations were employed to directly assess NRR and HER activities under the same reaction conditions. Results show that cobalt oxynitrides exhibit NRR activity at pH 10, involving the electrochemical reduction of both lattice-bound nitrogen and dissolved N2, although more HER activity was observed. In contrast, vanadium oxynitride films displayed HER inactivity at pH 7 and 10 but demonstrated NRR activity at pH 7, while titanium oxynitrides were active at pH 3.2 but inactive under neutral and basic pH conditions. These comprehensive studies highlight substantial variations in HER and NRR selectivity based on transition metal oxophilicity/azaphilicity, indicating distinct mechanisms governing NRR and HER mechanisms.

The Emergence of Arab Nation-State Nationalism as an Alternative to the Supranational Concept of Ummah
In this dissertation, I examine the political shift or reorientation of Arabs and Muslims from the supranational Ummah to the Western form of nation-state by attending to modern Arabic novel in the period between World War I and World War II. I explore the emergence of secularism in Arab national formation. One of my central arguments is that Arab nationalism is indeed a misleading phrase as it gives the impression of unity and coherence to a complex phenomenon that materialize in a number of trends as a form of struggle. In the first chapter, I defined the scope of my argument and the underlying structure and function of nationalism as a form of representation masked by nationalist ideologies. To investigate the reorientation of Arabs and Muslims from Ummah to adopting nation-state, I utilize Spivak's criticism of the system of representation along with Foucault's theorization of discourse. I argued along Edward Said that although the Western national discourse might have influenced the Arab nationalists, I do not believe they prevented them from consciously appropriating nationalism in a free creative way. I also explained that the Arab adoption of a secularist separatist nationalism was more an outcome than an effect in the …

An Evaluation of Cross-Function Stimuli in the Treatment of Automatically Maintained Problem Behavior
Noncontingent reinforcement (NCR) is a possible alternative to differential reinforcement of other behaviors (DRO) that may operate through a similar mechanism. In the research, the participant's problem behaviors were maintained by automatic reinforcement or even multiply maintained. NCR is the method to intervene with the participant who had no clinical effect on using sensory integration therapy (SIT) to reduce problem behaviors in the previous study. The results showed that NCR is an effective way to decrease the problem behaviors without extinction burst.

California Public Schools and Employees' Negligence of Supervision on School Property
We live in a culture where school systems are accused of being negligent or at fault for any undesired outcome. This can leave school districts and their employees anxious about potential consequences, regardless if the negligent claim is warranted or not. Therefore, there is a need for all educators to understand their responsibilities to provide a safe learning environment, and this may look different from state to state across the United States. The purpose of this study was to analyze how California state courts have interpreted the concept of sovereign immunity and tort claims filed against California public-school districts and their public-school employees related to negligence of supervision on school grounds. This legal research case study design was guided by the following research question: what are the exceptions to sovereign immunity regarding negligence related to the supervision of students as required by California statute? This study analyzed twelve various cases of California public-school districts and employees involving negligence in supervision claims on school grounds after the 1963 California Tort Claims Act was enacted. Based on the issue, rule, application, and conclusion of the twelve cases, eight were ruled in favor of the plaintiff or appellant, and four cases had final …

Leadership Practices and Processes that Close Opportunity Gaps for Socioeconomically Disadvantaged and Minoritized Students: A Case Study of a High-Needs Title 1 Elementary School
The purpose of this qualitative, single case study was to identify leadership practices and processes that contributed to the success of a single High Needs, Title 1 elementary school that has experienced acknowledged superior academic success, particularly for its minoritized and low socioeconomically disadvantaged students, as indicated by the school's success on the State of Texas Assessment of Academic Readiness (STAAR) tests. The study sought to explore the principal's and teachers' conception of leadership for success and to examine what effective practices and processes were employed at a high-needs, high-performing campus that accounted for its success. The study applied the culturally responsive school leadership (CRSL) framework to analyze the practices employed at the school. Results of the study, from interviews with the principal and a focus group of three teachers, indicated that not only did they apply the principles of the CRSL framework, which employed the critical self awareness, culturally responsive curricula and teacher preparation in a culturally responsive and inclusive school environment which engaged parents and students in community contexts, but they also enhanced their effectiveness through the provision of additional resources for teachers and students, with a heavy reliance on data to guide academic decisions.

Conditional Disclosure of Secrets and Storage over Graphs
In the era of big data, it is essential to implement practical security and privacy measures to ensure the lawful use of data and provide users with trust and assurance. In the dissertation, I address this issue through several key steps. Firstly, I delve into the problem of conditional secret disclosure, representing it using graphs to determine the most efficient approach for storing and disclosing secrets. Secondly, I extend the conditional disclosure of secrets problem from a single secret to multiple secrets and from a bipartite graph to an arbitrary graph. Thirdly, I remove security constraints to observe how they affect the efficiency of storage and recovery. In our final paper, I explore the secure summation problem, aiming to determine the capacity of total noise. Throughout the dissertation, I leverage information-theoretic tools to address security and privacy concerns.

Testing the Perceived Efficacy and Value of a Solar-Powered MoodleBox to Provide Sustainable Educational Support to Underdeveloped Areas
The dissertation aims to expand access through a low-cost technological innovation system S-MLS to learners in underdeveloped areas with difficulties in accessing education. Technology is advancing rapidly. However, many parts of the world need access to educational advances, which are hindered due to war, political situations, and low literacy and income. A qualitative phenomenological approach explores the lived experience using the solar-powered computing and learning management system (LMS) to support the development of educational access in underrepresented societies, developing countries, and rural areas where access to proper classroom education is non-existent. Proof of concept is used with a group of students in a rural area, a developing country, and within an underrepresented population to check the feasibility of using the equipment in a real-world setting. A technology acceptance model would be used to identify the user's perceived interest and user acceptance. The community of inquiry theory would find the first-hand experience and point of view of the learner. The student group interviews would be through semi-structured interviews. Observations, surveys, video/audio recordings, and artifacts would be gathered for further analysis. The data collected would be analyzed using interpretative phenomenology analysis (IPA), close examination, and management of development themes through thoughts, observations, …

Kinetics and Atmospheric Chemistry Studies of Halogenated Species
Quantitative information about halogenated hydrocarbons is important for understanding their impact on atmospheric ozone chemistry and climate change, their regulation, and the devising of improved substitutes. The Montreal Protocol aimed to regulate the utilization and manufacturing of hydrochlorofluorocarbon compounds (HCFCs), contributing to ozone layer depletion. The 2016 Kigali Amendment to the Montreal Protocol agreement, Annex C listed 274 HCFCs. Only 16 of them have been measured experimentally. The rest were set to zero by default. These reported global warming potentials (GWPs) play a crucial role in formulating policies for gradually reducing the usage and production of HCFCs to prevent atmospheric impact. Here we are studying 1-chloro-1-fluoro-ethane (CH3CHFCl) as a test of past theory. There are no prior experimental measurements of the reactivity of CH3CHFCl with hydroxyl (OH) radicals, which primarily determines its atmospheric lifetime, nor of its infrared (IR) spectrum. Saturated hydrofluorocarbons (HFCs) are non-ozone depleting substitutes for chlorofluorocarbons deprecated under the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, but they exhibit high global warming potentials (GWPs) and the Kigali Amendment adopted in 2016 outlines their phase down. Unsaturated HFCs offer more reactive alternatives, whose likely short atmospheric lifetimes would imply small GWPs. Because their GWPs are …

An Analytical Study of the Suite for Violin and Piano (1935), Op. 6, by Benjamin Britten (1913-1976)
The Suite for Violin and Piano, Op. 6 is one of the least-known compositions by Benjamin Britten. It has been considered unfavorably by critics and scholars due to its puzzling mixture of tonal and post-tonal elements. However, this dissertation argues that the suite is composed with a clear tonal framework, and its unique mixed tonal-post-tonal language justifies an in-depth analysis. This analytical study utilizes a linear progression technique - the voice leading produced by passing tones and neighbor notes around focal pitches - to identify tonal areas of the suite.

Cyber Addiction and Information Overload and Their Impact on Workplace Productivity
The research examines the relationship between cyber addiction (excessive use of the Internet, CA), information overload (IO), and assesses their impact on workplace productivity. A multi-methods approach is used employing the Internet Addiction Test (IAT) and a quantitative survey design to assess and test the stated hypothesis. The study used random sampling methods targeting 150 respondents from different information technology departments of various organizations. The study hypothesizes that CA and IO have a reciprocal association, which adversely affects workplace productivity and employee performance. From the findings, IAT scores increase with an associated possibility of reporting burnout, fatigue, and other components associated with CA and IO. Also, CA and IO were significantly correlated, as evaluated by the chi-square test, although the same approach did not yield significant associations between CA and perceived internet dependence. Other findings CA components, such as social media use, significantly associated with task postponement and burnout. As well, CA affected IO with substantial impacts on workplace productivity. The paper highlights managerial aspects that organizations should consider in optimizing the output of their staff. Recommendations include wellness programs, altering the leadership and management styles, and sensitizing the employees on the adverse effects caused by the two variables.
