Automated Scoring Of Prosody In Oral Reading Fluency: Integrating Acoustic And Sentence/Chunk-Level Silence Features With Machine Learning, Kuo Wang

Education Policy and Leadership Theses and Dissertations

Prosody, the ability to read with appropriate variation in pitch, duration, pausing, and stress, is an important (and challenging to measure) dimension of oral reading fluency (ORF) and comprehension. ORF prosody is currently measured through human raters and rubric-based scoring systems (e.g., the National Assessment of Educational Progress (NAEP) or the Multidimensional Fluency Scale (MDFS scales). The rating process is labor and resource-intensive and introduces rater bias. Recent work has shown acoustic features to predict prosody ratings; however, their models had low generalization performance on cross-domain data (unseen passages and student samples).

The present study investigated the automated assessment of …

Conflict-Mediated Group Size Regulation: A Theory Of Supraoptimal And Suboptimal Group Size, Eric Schniter

ESI Working Papers

Observed group sizes rarely match the size that would maximize what each member gets from belonging. We propose a two-part theory in which group size is regulated by two related conflicts: insider-outsider conflict over admission, and within-group conflict as crowding, competition, and social tensions intensify with size. Three strategies are available: admission, exclusion, and fission. The first part shows that even when exclusion is unavailable, fission dynamics alone drive group size away from the optimum in both directions, with the pattern set by how prospective joiners encounter groups and by the geometry of fission. When joiners compare groups across a …

Corn Yield And Tissue-Potassium Response To Potassium Fertilization, Wyatt A. Rongey

Graduate Theses and Dissertations

Potassium (K) deficiency is an increasingly important yield-limiting factor for irrigated corn (Zea mays L.) in Arkansas, where below optimum soil-test K (STK) acreage is increasing and visible K deficiencies or hidden K hunger threaten yield and profitability. Improving K management for modern, high-yielding hybrids require refining soil-test-based fertilizer recommendations and defining growth-stage-specific tissue-K sufficiency ranges that diagnose deficiency before irrecoverable yield loss occurs. This research aimed to i) quantify corn grain yield and yield component responses to K fertilization across a wide range of STK levels; ii) determine the frequency and magnitude of agronomically and economically meaningful yield responses …

Remote Sensing-Derived Urban Heat Islands And Land Surface Phenology, Raihan Sorker

Graduate Theses and Dissertations

Thermal remote sensing has been widely applied to characterize urban heat islands (UHI) and their relationship to land use; however, few studies have explored the relationship between land surface temperature (LST) and land surface phenology (LSP). This study focused on the relationship between LST and LSP in the metropolitan region of Kansas City, Missouri, USA using Landsat 8 satellite images from 2015 to 2024. Thermal and normalized difference vegetation index (NDVI) time series were processed using Google Earth Engine to derive annual LST metrics alongside phenological indicators including timing of green-up and senescence as well as growing season length. Individually, …

Localizing And Repairing Backdoor-Sensitive Layers In Pre-Trained Language Models For Secure Fine-Tuning, Sunanda Das

Graduate Theses and Dissertations

Task-agnostic backdoor attacks can contaminate pre-trained language models (PLMs) in a way that survives downstream adaptation, even under full fine-tuning, making it difficult for practitioners to trust third-party checkpoints. Existing defenses often rely on privileged assumptions (e.g., access to poisoned data or trigger/target knowledge), thereby limiting their applicability in realistic settings. We present DiSec (Disentanglement of potentially adversarial weights for Secure fine-tuning), a robust and label-efficient purification framework that uses only clean auxiliary text and does not rely on downstream supervision or attack signatures. DiSec elicits model-internal signals from this clean data to separate suspicious parameter components that are inconsistent …

Classical Liberalism And Property, Thomas W. Merrill

Faculty Scholarship

Classical liberalism is characterized by several key attributes. Its central normative criterion is the well‑being of the individual, not some aggregate like society or the nation‑state. Individuals are presumptively regarded as responsible actors, capable of judging their own best interests and accountable for their actions that interfere with the well‑being of others. Because individuals are presumptively regarded as responsible actors, there is a strong preference for imposing only minimal obligations on them through the power of the state, and these usually involve general negative duties that are universal in character, chiefly to forbear from using force or fraud to interfere …

There Is No Free Benchmark: An Institutional View Of Legal Ai Benchmarking, Neel Guha, Andy K. Zhang, Christine Tsang, Christopher D. Manning, Julian Nyarko, Daniel E. Ho

Faculty Scholarship

Despite substantial excitement around the use of AI in law, little information exists on the performance and associated risks of the domain’s widely marketed tools. Recent work, for instance, has demonstrated the significant potential for “hallucinations” — wherein models make up facts, law, and precedent — leading Chief Justice Roberts to spotlight this risk in his annual report on the judiciary. We argue that there is a need for public AI benchmarking in law. First, relative to other AI application domains, the legal AI ecosystem lacks legibility — there is little information about the design and performance of many commercial …

Alternative Methods To Improve Livestock Performance While Grazing Low-Quality Forages., Ivan Raynard Thomas Jr

Graduate Theses and Dissertations

Stocker cattle producers in the southeastern part of the U.S. heavily depend on traditional forages such as bermudagrass [Cynodon dactylon] pastures during the warm season for grazing. Summer annual forages offer stocker cattle operations a valuable alternative source of forage. These forages have high yield potential and can help extend the grazing season. This is particularly beneficial during the summer months when traditional forage sources may be limited. Warm-season annual grasses may experience a decrease in crude protein concentrations during late summer and early fall. As a result, it may be necessary to find alternative sources of crude protein or …

A Dual Analysis Of Generic Stereotypes, Shaoneng Xu

Graduate Theses and Dissertations

In my thesis, I provide a dual-analysis on generic stereotypes, including a semantic analysis that focuses on the truth conditions of generic sentences as well as a pragmatic analysis that focuses on the normative force of generic stereotypes. The thesis contains two parts: In the first chapter, I make a semantic analysis of generic stereotypes based on Lemeire’s (2020) paper. I unpack the general concept of generic sentences and their truth-conditions. I also discuss Lemeire’s rebuttal strategies to offensive generic stereotypes, and add to it by indicating that generics can also carry normative forces. In the second chapter, I make …

Evaluation Of A High Protein Low Oligosaccharide Soybean Meal In Poultry Production, Kasey Matusik

Graduate Theses and Dissertations

The purpose of this study was to evaluate the influence of feeding a high protein, low oligosaccharide soybean meal to optimize poultry nutrition by the effects of feeding the soybean meal to roosters, broiler chickens, and turkeys. Two research objectives were evaluated to determine whether high protein, low oligosaccharide soybean meal would have increased nutritional value. The first objective assessed the metabolizable energy (ME) content of a high protein, low oligosaccharide soybean meal compared to a conventional soybean meal. Using roosters, broiler chickens, and turkey poults, three bioassays were conducted to evaluate the ME of the soybean meal. Results demonstrated …

The Role Of Speculators In The Agricultural Futures Market And Their Impact On Prices, Clement Asamoah

Graduate Theses and Dissertations

The study evaluates the impact of speculative activity on agricultural commodity returns, specifically in the corn, soybeans, rice, and oats markets. The study also analyzed the influence commodity returns have on speculative positions. Weekly data from the Commodity Futures Trading Commission were used as a proxy for speculative activity, and futures data were also retrieved from Barchart. Vector Autoregressive models and the Granger Causality tests were estimated to identify the relationships between returns and speculation. The paper found that speculative positions do not Granger-cause returns over the course of a week except for rice Tuesday results, which recorded a statistically …

Making Meaning In Gender Affirming Therapy: Voices Of Transgender And Gender Diverse Individuals, Shelby Freeman

Graduate Theses and Dissertations

Transgender and gender diverse (TGD) people frequently seek out counseling services and experience greater mental health difficulties than the general population. Oppressive political and social structures are often cited as a main contributor to mental health disparities. As antitransgender laws and sentiments increase in the U.S., the likelihood of mental health professionals encountering TGD clients will also increase. This requires specific competencies in how to provide effective gender-affirming mental health services. Affirming MHPs are more accessible to TGD clients now than ever due to increases in provider training and improved attitudes. However, previous research revealed that MHPs who identify as …

Advancing Social Media Analytics And Personalized Generation Via Transfer Learning, Discourse-Aware Modeling, And Collaborative Modeling, Gibson Nkhata

Graduate Theses and Dissertations

Social media platforms have become central to information exchange, shaping public opinion across social, political, and economic domains. However, the massive volume of user-generated content, combined with its informal, nuanced, and often noisy nature, presents significant challenges for automated analysis and generation. Tasks such as stance detection, rumor verification, and personalized content generation are further complicated by sarcasm, evolving discourse structures, and diverse user preferences. Addressing these challenges requires models that can effectively leverage linguistic nuance, conversational dynamics, and collaborative user signals. Transfer learning has emerged as a powerful paradigm for improving performance in low-resource and complex language understanding tasks. …

Effectiveness Of Pcit With Toddlers In A Community-Based Sample: Special Considerations For Youth With Neurodevelopmental Conditions, Rebecca Scott Bradley

Graduate Theses and Dissertations

The early caregiving environment serves as the context in which young children develop emotional regulation abilities. While supportive, responsive caregiving is crucial for helping children regulate their own emotions in times of stress, disruptions to the parent-child relationship may set the stage for poor emotion regulation throughout childhood. Emotional and behavioral problems, particularly in children with neurodevelopmental conditions, may stem from early difficulties with emotion regulation. If left untreated, emotion dysregulation in children can mark a trajectory towards continued social-emotional concerns and family disruption; as such, the toddler years represent an ideal time for intervention. Parent-Child Interaction Therapy for Toddlers …

Challenges And Opportunities In Dry Aging: Producer Perspectives And Valorization Of Dry- Aged Waste Products, Peyton Scout Arnold

Graduate Theses and Dissertations

Despite the projected increase in the dry aging market, producers may be hesitant to incorporate dry aging practices. This thesis aims to identify primary concerns faced by producers in implementing a dry aging program. Semi-structured interview surveys were conducted via Qualtrics (N = 100). Results indicated that an “advanced” level of dry aging knowledge correlated with a higher importance in the use/sale of dry aged products (P = 0.02). Cost, demand, and sourcing were the top three concerns of producers practicing dry aging. Those considering implementation were concerned with cost, processing parameters, safety, demand, and sourcing. No significant differences were …

Design, Fabrication, And Testing Of A Pdms-Based Nanochannel Using Nano Embossing, Cooper James Haskamp

Graduate Theses and Dissertations

DNA sequencing has become increasingly important in the field of biomedical research and clinical applications. Currently, the most well-established sequencing technique is ‘Sequencing by Synthesis’ with accuracy in the range of 99.2% to 99.74% and sequencing lengths of only 300 base pairs. Sequencing by Synthesis is a lab-based method that requires expensive equipment and fast parallel computing. It is not suitable for portable, on-site applications. A new technique known as ‘nanopore’ was developed to meet these requirements. Nanopore is an electrical sequencing method that relies on the translocation of a DNA molecule through a nanoscale pore, where the blockage current …

Arkansas’ Crippled Children’S Homes & The Politics Of Polio, Rylie Ford

Graduate Theses and Dissertations

Most of the work in the field of disability history has centered on the Northeastern part of the United States and regions with large urban centers, therefore, excluding Southern and rural perspectives. This omission is particularly problematic when roughly 79% of the Black population in the United States lived in the South in 1940. The aim of this study is to contribute a Southern perspective to disability studies and Black medical history by tracing the development of services and aid for children with physical disabilities in Arkansas. Employing the frameworks from the social model of disability and Black disability politics, …

Religious Higher Education In Prison In The United States: The Importance Of Well-Being, Robin L. Labarbera

Journal of Global Education and Research

A growing body of scholarship suggests that incarcerated individuals who participate in education programs, particularly those grounded in faith, are better positioned for lasting community reintegration and positive long-term outcomes. Using a mixed-methods evaluation design, the author examines two interrelated questions: whether faith-based higher education is associated with enhanced well-being among current participants and whether program graduates carry those well-being gains into post-release life. Drawing on group interviews with 109 incarcerated men and women across six U.S. facilities and surveys from 157 participants in four states, the study found that participation in a prison-based theological education program was associated with …

Sputtered Transport Layers Enabling Ambient-Air Processed Cspbi3 Perovskite Solar Cells, Shamik Datta, Md Abdul Kuddus Sheikh, Md Shazarul Islam, Mohammed Jasim Uddin, Hasina Huq

Electrical and Computer Engineering Faculty Publications

Perovskite solar cells offer promising efficiency compared to traditional technologies. In this study, NiOx and ZnO were employed as charge transport layers using a magnetron sputtering process within a p-i-n architecture (ITO/NiOx/CsPbI3/ZnO/Au). This approach produced uniform, low-defect interfaces and supports low-temperature, scalable fabrication suitable for flexible substrates. Our investigation, using techniques such as X-Ray Diffraction (XRD), UV-Visible spectroscopy, Scanning Electron Microscopy (SEM), and Atomic Force Microscope (AFM), revealed the formation of uniform layers deposited by the magnetron sputtering process. The photoactive CsPbI3 layer was deposited via a spin coating solution process. UV-Visible spectroscopy revealed strong absorbance in the wavelength range …

Spatially Dissecting Drivers Of Inter- And Intra-Tumoral Heterogeneity In Kenyan Breast Cancer, Mustapha Abubakar, Shahin Sayed, Hela Koka, Scott Lawrence, Karun Mutreja, Xing Hua, Petra Lenz, Samuel Anyaso-Samuel, Rosemary Kamau, Beryl Ooro

Pathology, East Africa

Despite growing evidence on the impact of intra-tumoral heterogeneity (ITH) in breast cancer (BC), its biological drivers and clinically relevant mitigation strategies remain poorly characterized, particularly in low-resource settings where spatial profiling is rarely applied. To address this gap, we conducted a comprehensive, multiplatform spatial profiling study of BC in a Kenyan population. Using the NanoString GeoMx™ Digital Spatial Profiler, we quantified 44 protein markers across 707 spatially defined, PanCK-segmented Areas of Illumination (AOIs) from 31 tumors. All tumors exhibited measurable ITH, with one-third showing marked heterogeneity. Sixteen patients exhibited two or more intrinsic subtypes within their tumors, three of …

INTRODUCTION: Declining nicotinamide adenine dinucleotide (NAD+) may elevate risk of Alzheimer's disease.

METHODS: We conducted a 12-week double-blind, randomized, placebo-controlled pilot study to evaluate the safety, tolerability, and preliminary efficacy of the NAD+ precursor, nicotinamide riboside (NR), for enhancing cognitive function and cerebral blood flow (CBF) in adults with amnestic mild cognitive impairment (aMCI).

RESULTS: 42 participants completed the study (NR = 22, placebo = 20). Adherence was similar between groups with no serious adverse effects. Blood NAD+ increased twofold in the NR group. There were no improvements in cognitive function (primary outcome), total CBF, or blood pressure (secondary outcomes). …

Examining The Effectiveness Of Nature Metaphor Patterns For Cultivating Intimacy, Acceptance, Relationship Satisfaction, Self-Compassion, And Positive Communication In Couples, Jenna Rice, Sarah Fraher, Elizabeth Engelkamp, Melissa Mcternan, Hannah Grigorian, James Cordova

Psychology

Effective couple interventions, such as Integrative Behavioral Couple Therapy and the Relationship Checkup, include the labeling of common relationship patterns. This study hypothesized that a micro-intervention using nature metaphors, such as “Porcupine–Turtle,” would produce greater improvements in relationship health relative to descriptive labels such as “Approach–Withdraw.” Twenty-five couples were presented with nature metaphor patterns, while 24 couples were presented with descriptive patterns. Several measures of relationship health showed significant improvements across both groups, while other measures showed significant improvements for descriptive patterns only. Generally, nature metaphor patterns were initially rated as more novel and more resonant. Broadly, these results add …

Design And Evaluation Of A Distributed Ticket Booking System Using Cqrs And Hybrid Consistency Models, Tai Nguyen Vo, Sangwhan Cha

Harrisburg University Other Works

This paper presents the design and evaluation of a Distributed Ticket Booking System (DTBS) built to handle extreme concurrency in high-traffic digital environments. Motivated by real-world failures such as the 2022 Taylor Swift Eras Tour sale—where 14 million simultaneous requests overwhelmed Ticketmaster—the system addresses the fundamental conflict between strong consistency and high availability under massive demand. The proposed solution adopts the Command Query Responsibility Segregation (CQRS) pattern to decouple read and write operations, and applies a hybrid consistency model grounded in the CAP theorem: a CP-oriented booking subsystem with Redis-based distributed locking, and an AP-oriented search subsystem using Elasticsearch for …

Advancing Sensing And Structural Health Monitoring Of Non-Conventional Space Structures, Scott Bender

Doctoral Dissertations and Master's Theses

Future lunar and deep-space missions will require new structural concepts that reduce mass while maintaining reliability. Two technologies that have received significant attention are inflatable habitats and additively manufactured structures; however, challenges remain in their characterization, validation, and long-term monitoring. This dissertation investigates methods to improve the testing and sensing of these non-conventional aerospace structures through the use of advanced photogrammetry and embedded distributed fiber-optic sensors. A color-filtering digital image correlation technique was developed to isolate orthogonal strain directions in woven inflatable structures, providing improved characterization of biaxially loaded softgoods. In addition, methods were developed to embed distributed fiber-optic sensors …
