Improving Engagement Through Readers' Theater: A Systematic Literature Review And Teacher Process Portfolio With Program Proposal, Karen K. Crum

Theses and Dissertations

This project investigated the impact of Readers’ Theater on elementary students’ attitudes toward reading, the teacher’s perception of effectiveness of Readers’ Theater as a tool to improve reading comprehension, and students’ test-related anxiety, within the context of the Mississippi Academic Assessment Program (MAAP) mandated by the Literacy-Based Promotion Act. While existing literature has highlighted Readers’ Theater as an effective instructional strategy that engages reluctant readers and enhances both reading fluency and comprehension through repeated, performance-based readings, gaps in current research exist regarding Readers’ Theater effectiveness as an instructional strategy to mitigate reading- and test-anxiety. Through research questions focused on how …

Social Validity Of Functional Analysis Variations, Rita M. Druffner

Theses and Dissertations

The functional analysis was developed to systematically identify the antecedent and consequent conditions mediating challenging behavior. Modifications to the traditional procedures have been developed to address barriers to implementation, including duration, environmental control, and safety. Much of the research surrounding functional analyses addresses effectiveness, barriers to implementation, and practitioner acceptability. However, there is a lack of research assessing caregiver social validity of functional analysis procedures. Social validity is the assessment of the goals, procedures, and outcomes of behavior analytic practice. Even though there has been advocacy for including measures of social within behavior analytic research and practice, there is limited …

Evaluation Of Furrow-Irrigation And Agronomic Management In Mississippi Rice (Oryza Sativa L.), Thomas W. Eubank Iv

Theses and Dissertations

A new non-transgenic rice has been developed called ROXY, which is resistant to formulations of oxyfluorfen. Utilizing the ROXY rice production system in a furrow-irrigated system could help combat troublesome terrestrial weeds and be a viable option for producers.

Theses and Dissertations

Over the past few decades, the National Weather Service (NWS) has continued to improve impact-based decision support services (IDSS) efforts to strengthen communication with core partners. This study addressed how a new spatially hazard-specific vulnerability tool called the Brief Vulnerability Overview Tool (BVOT) may impact how NWS meteorologists tailor messaging to their core partners. It was found that relationship building between NWS meteorologists and core partners is key to enhancing trust, especially during blue sky days. This was done by learning core partners’ needs, thresholds, and communication styles when presenting weather information. Core partners also noticed cues from NWS meteorologists …

Towards Applying Artificial Intelligence To Solve Np-Complete Problems Using Quantum Computing, Andrew Robert Haverly

Theses and Dissertations

This dissertation explores the methodology for more thoroughly entangling artificial intelligence and quantum computing. This is explored through a background search of problems solved using Grover’s quantum algorithm, a new quantum protein folding and drug discovery algorithm, using Grover’s algorithm to train quantum artificial neural networks, using quantum artificial neural networks for reinforcement learning, mapping classical assembly instructions to quantum circuits to make quantum programming easier, and using prompt engineering to get a classical artificial intelligence agent to solve an NP-Complete problem using a Grover’s algorithm. This method not only simplifies the creation of algorithms but also opens new avenues …

Tabletop Role-Playing Games As A Therapeutic Intervention: Translating Ttrpgs To Therapy, Joanne Adelle Hillerman

Theses and Dissertations

The purpose of this study was to examine the aspects of tabletop role-playing games, or TTRPGs, that are appealing to therapists, aspects of TTRPGs that may be challenging for therapists to implement, and to identify outside factors that may associated with therapists’ interest in using TTRPGs. This study used the technology acceptance model (Davis, 1989) as a theoretical framework. A sample of therapists and mental health workers (N = 102) answered survey questions on their perceptions of the ease-of-use and usefulness of TTRPGs in therapy, their likelihood to use TTRPGs in therapy, and additional items measuring outside influences on their …

Topnet R1: A Multi-Stage Ai Framework For Topic Discovery In Scientific Abstracts, Md Elias Hossain

Theses and Dissertations

Scientific abstracts are rich sources of knowledge, yet extracting meaningful topics remains challenging due to limitations in existing topic modeling techniques. Traditional methods often struggle with interpretability, scalability, and contextual understanding. To overcome these issues, we introduce TopNet R1, a multi-stage ensemble framework that integrates traditional topic models with contextual embeddings from Bidirectional Encoder Representations from Transformers (BERT) and Generative Pre-trained Transformer 4 (GPT-4) large language models (LLMs). Top- Net R1 operates in three phases: (1) topic generation using Latent Dirichlet Allocation (LDA), Non-Negative Matrix Factorization (NMF), Latent Semantic Analysis (LSA), and Hierarchical Dirichlet Process (HDP); (2) LLM-assisted pattern recognition …

Documenting Children’S Use, Physical Activity, And Social Play In Tom Lee Park’S Playscape, Laurel Kelton

Theses and Dissertations

The benefits of nature and physical activity on children’s health and development are well documented. However, many children lack access to nature and physical activity. Researchers have found that “innovative playgrounds” —which, by definition, are more likely to include natural elements that facilitate nature immersion— are associated with increased physical activity and duration of stay. This thesis is a case study of a public innovative playground at Tom Lee Park. It sought to understand the playground’s areas and physical characteristics that have higher levels of use, physical activity, and social play and longer durations of stay. Data was collected over …

Synthetic Mrna Induced Tf1.17-Specific Antibody Response Against Tritrichomonas Foetus For Preputial Delivery In Bulls, Kenzie Mcatee

Theses and Dissertations

Bovine trichomoniasis, caused by Tritrichomonas foetus, remains a persistent reproductive disease in cattle due to asymptomatic carriage in bulls and lack of effective treatments. This thesis evaluated the use of synthetic mRNA to drive expression of TF1.17- specific antibodies, targeting a conserved surface adhesin essential for parasite colonization. Membrane-anchored and secreted IgG1 constructs were transfected into bovine kidney cells, resulting in time-dependent antibody expression verified via NanoLuc luminescence. In vivo, aerosolized mRNA administration to bull calves led to localized antibody expression in preputial secretions. Although immunofluorescence assays detected fluorescence signal, high background limited interpretation of specific binding to T. foetus. …

Family Matters: How Caregiver Influence And Internal Locus Of Control Relate To Academics, Maia Mclin

Theses and Dissertations

Academics in college predicts life outcomes; students from lower socioeconomic status (SES) backgrounds often face greater challenges. One such population, consisting of many individuals from marginalized backgrounds, are those raised by nontraditional parents. This study investigated predictors of academics among 357 college students, examining authoritative parenting style, intrinsic motivation, academic locus of control (LoC), SES, and caregiver type (parental vs. non-traditional). Academics was assessed using two composite scores: 'academic knowledge' (GPA/ACT) and 'compensatory attention' (working memory via n-back task accuracy and attention/concentration via SMALSI-C). Hierarchical regressions revealed that higher authoritative parenting, higher SES, and being raised by biological parents significantly …

Unboxing The Black Box: Graph-Based Interpretability In Transformer Models, Ramak Nassiri

Theses and Dissertations

This thesis introduces a novel interpretability framework for transformer encoder models by hypothesizing that their internal embedding updates define a state transition system. We propose that transformers implicitly learn token-to-token influence dynamics, which can be analyzed using graph-theoretic methods. To validate this, we construct transition graphs from embedding changes and rank token importance using the PageRank algorithm. We develop two transformer models from scratch: a self-supervised model that incorporates serotype tokens to learn contextualized embeddings, and a supervised model initialized with these embeddings. Cosine similarity analysis of their token influence patterns reveals strong structural alignment, with values exceeding 93%. This …

Augmenting Healthcare Communication: Context-Aware Ai Frameworks For Clinical Decision Support And Automated Summarization, Subash Neupane

Theses and Dissertations

Healthcare communication is plagued by fragmented medical knowledge, patient misunderstanding of care plans, and clinician burnout from documentation burdens. These inefficiencies cost the U.S. healthcare system over $300 billion annually due to preventable nonadherence and administrative waste [47, 19]. While Artificial Intelligence (AI) technology like Large Language Models (LLMs) offer potential solutions, existing systems fail to deliver personalized, context-aware guidance or automate documentation without sacrificing accuracy. This dissertation addresses these gaps through three novel context-aware AI frameworks such as MedInsight, ClinicSum, and ClinicDuo. MedInsight leverages a multi-source context augmentation approach to synthesize patient centric medical responses by integrating Electronic Health …

Decision-Making And Execution Skill Estimation In Continuous Action Space Domains, Delma I. Nieves-Rivera

Theses and Dissertations

In many real-world domains with continuous action spaces, an agent’s performance is driven by two key factors: its decision-making skill, or ability to select high-quality actions, and its execution skill, or precision in carrying out these actions. However, accurately evaluating these skills, particularly when direct information about the agent’s intentions is unavailable, remains a challenging problem. This research addresses this need by developing a theoretical framework and proposing novel estimation methods to assess both decision-making and execution skills based solely on observable data: executed actions and their associated rewards. The work consists of six core studies focused on developing and …

In Good Times & Bad: Measuring Ambivalence In Custodial Grandparents, Marin Gail Olson

Theses and Dissertations

Like other forms of caregivers, custodial grandparents experience both the joys and trials of raising their grandchildren. This culmination of positive and negative feelings is called “caregiver ambivalence." It has only recently been studied in relation to caregiver burden and wellness in the form of caregiver ambivalence theory (CAT). By collecting data from approximately 395 custodial grandparents via an online survey, the current study aimed to test if custodial grandparents’ feelings of burden influence their perceived well-being and if feelings of ambivalence mediate this relation. Implications of this research include identifying areas of strength and growth within custodial grandparents and …

A qualitative study was designed to examine the key components of the perceptions of job satisfaction, the motivating factors leading to it, and the perceptions of the position through the lens of the teacher assistant. Five elementary teacher assistants from a single school in a southern state participated in semi-structured interviews. Key …

The Effectiveness Of Positive Behavioral Interventions And Supports (Pbis) In Title I Secondary Schools, Robyn Rush-Grace

Theses and Dissertations

Positive Behavioral Interventions and Supports (PBIS) is grounded in behaviorist theories, particularly Skinner's operant conditioning, which suggests that positive reinforcement can shape behavior over time. PBIS uses a tiered system to address student behavior, providing universal support for all students (Tier 1), targeted interventions for students who need more support (Tier 2), and intensive, individualized interventions for the few students who exhibit the most significant behavioral challenges (Tier 3). The literature on PBIS generally supports its effectiveness in reducing office discipline referrals, suspensions, and expulsions, as well as improving student behavior and overall school climate. Research specific to Title 1 …

Mastering Skills Together: Effects Of Video Modeling On Parent-Implemented Academic Intervention, Chelsea S. Thorpe

Theses and Dissertations

Reading proficiency is a fundamental skill for academic success and long-term developmental outcomes. Yet, despite ongoing efforts to strengthen literacy education, a significant number of students continue to face reading difficulties that hinder comprehension, critical thinking, and overall academic achievement. National data demonstrate the urgency of this issue. The 2024 National Assessment of Educational Progress (NAEP) reported that 40% of fourth-grade students and 33% of eighth-grade students scored below the Basic level in reading, marking the highest rate on record for eighth graders. Early reading challenges can often lead to other academic and psychosocial challenges such as low achievement, low …

Estimating Reliability Of Electric Vehicle Charging Ecosystem Using Principle Of Maximum Entropy, Himanshu Tripathi

Theses and Dissertations

This thesis addresses the challenge of estimating electric vehicle (EV) charging system reliability against unpredictable threats like cyberattacks and extreme weather, where traditional methods fail. We utilize the Principle of Maximum Entropy (PME), a statistical tool that provides unbiased risk estimates using limited information. Applied to the EV charging ecosystem, our case study shows how PME models stress factors to predict failures and optimize maintenance. This approach extends beyond EVs to other complex systems with scarce data, such as smart grids or healthcare devices. By linking uncertainty directly to reliability, PME offers a universal method to improve decision-making under unpredictable …

Academics Vs Athletics: Prioritizing The Students In Student-Athletes And The Importance Of Their Return To The Classroom, Stephen Walker

Theses and Dissertations

The Mississippi High School Activities Association (MHSAA) aims to enhance student- athletes' educational experiences but Law 6.5.1 inadvertently causes students to miss 300 hours of academic instruction annually. This dilemma forces school districts to choose between robust sports programs and rigorous academic schedules, ultimately creating a disadvantage for students. While participation in sports has been linked to improved academic performance, the current structure disproportionately allocates resources to athletics over academics, with only 51% of schools offering after-school academic programs compared to 77% for sports. This paper discusses the benefits of sports, including higher attendance and graduation rates, but also highlights …

An Examination Of Potential Occupational Horizons And Site Integrity Through Site Formation Processes At Aklis, St. Croix, Jesse Weaver

Theses and Dissertations

The Aklis Site, located in the Sandy Point National Wildlife Refuge on St. Croix, contains both an artifact-dense shell midden and numerous human burials actively eroding into the Caribbean Sea. Here I examine the records and collections from the site through the lens of site formation theory to ask: (1) Are there detectable occupational horizons within the midden?; (2) To what extent have cultural and non-cultural transforms affected the integrity of the midden? and; (3) If detected, are these occupational horizons of sound enough integrity to allow for future radiocarbon dating that might clarify culture chronology for the greater West …

The optical trapping system used in this work is based on the universal optical trap (UOT), which is capable of trapping and manipulating a wide variety of particle types. These include both transparent …

The Interplay Of Biomarkers And Psychosocial Variables In Ipv Perpetration, Arturo L. Cantos, María L. Mondolfi, K. Daniel O'Leary

Psychological Science Faculty Publications

Relevant biopsychosocial factors, including testosterone (T) and cortisol (C) levels, adverse childhood experiences (ACEs), and difficulties in emotion regulation, have been implicated in IPV perpetration. However, further research is needed to clarify how biomarkers and psychosocial variables interact. The authors herein predicted that emotion regulation difficulties would moderate the association between ACES and IPV perpetration. The sample consisted of 30 IPV perpetrators aged 18 to 51 (M = 30.80, SD = 8.43) and 30 control non-perpetrator participants aged 18–35 (M = 24.13; SD = 4.28). All participants provided saliva samples to assess T and C levels and completed a sociodemographic …

The Relationship Between Hindrance Demands And Work Engagement: The Moderating Role Of Resilience, Adoré Davis

Master's Theses

The coronavirus pandemic decreased work engagement globally due to increased hindrance demands. Many organizations were motivated to increase work engagement, which is positively correlated with beneficial organizational outcomes. The intention of this study is to examine if personal resources like resilience moderate the relationship between hindrance demands and work engagement. Hindrance demands are refined from job demands and hindrance stressors, which are stressors that impede progress in employees. Resilience is a personal resource correlated with pro-social behavior, internal locus of control, and higher levels of empathy. Resilience as a personal resource has mainly been studied as a predictor of work …

More Than A Ramp: Rethinking School Design For Sensory And Cognitive Inclusion, Andrew Ho

University Honors Theses

This thesis advocates for the integration of the ASPECTSS framework, developed by Magda Mostafa, into legislative standards that would govern the design of educational environments that accommodate students with Autism Spectrum Disorder (ASD). Drawing on evidence from a case study demonstrating significant improvements in student behavior and overall satisfaction through ASPECTSS-based interventions, the thesis highlights the urgent need for these principles to move beyond voluntary adoption and rather, toward enforceable design mandates.

The ASPECTSS framework includes the seven following criterias; Acoustics, Spatial Sequencing, Escape Spaces, Compartmentalization, Transitions, Sensory Zoning, and Safety. This model provides a comprehensive and actionable approach to …

We Who Are Not Cared For: Social Death, The Lie Of Educational Equity, And A Radical Replanting Praxis, Chantell Wesley

University Honors Theses

This thesis examines how the concept of social death, as theorized by Orlando Patterson and expanded by Frank B. Wilderson III and Christina Sharpe, can serve as a transformative foundation for culturally informed care practices within academic institutions. Arguing that traditional equity efforts and even critical race interventions often fall short by focusing on reform within inherently anti-Black systems, I propose a new framework: Radical Replanting Praxis. Using the metaphor of education as a tree, this praxis calls for a shift in attention from reforming institutional "roots" to transforming the "soil"--the relational, ideological, and everyday conditions in which …

Artificial Transneurons Emulate Neuronal Activity In Different Areas Of Brain Cortex, Rivu Midya, Ambarish S Pawar, Debi P Pattnaik, Eric Mooshagian, Pavel Borisov, Thomas D Albright, Lawrence H Snyder, R Stanley Williams, J Joshua Yang, Alexander G Balanov, Sergei Gepshtein, Sergey E Savel'ev

2020-Current year OA Pubs

Rapid development of memristive elements emulating biological neurons creates new opportunities for brain-like computation at low energy consumption. A first step toward mimicking complex neural computations is the analysis of single neurons and their characteristics. Here we measure and model spiking activity in artificial neurons built using diffusive memristors. We compare activity of these artificial neurons with the spiking activity of biological neurons measured in sensory, pre-motor, and motor cortical areas of the monkey (male) brain. We find that artificial neurons can operate in diverse self-sustained and noise-induced spiking regimes that correspond to the activity of different types of cortical …
