From Innovation To Interaction: Processes Shaping Animal Assisted Therapy Implementation In Outpatient Settings In The United States, Rachel Rachlinski

LSU New Orleans Theses and Dissertations

Animal assisted therapy (AAT) is an emerging mental health specialty marked by rapid growth, inconsistent training pathways, and the absence of regulatory oversight. Although professional organizations have published competencies and guidelines, no regulatory body ensures that educational programs or licensed practitioners adhere to these standards, leading to wide variability in practice and potential risks to clients and animals. This constructivist grounded theory study examined the processes shaping how licensed mental health providers understand and implement AAT in outpatient settings across the United States, with attention to the influence of training, supervision, and prior clinical experience.

Autonomous Deficiency Detection And Vision-Language Summarization For Underground Infrastructure On Embedded Edge Systems, Johny Lopez

LSU New Orleans Theses and Dissertations

Aging underground infrastructure poses significant risks to public health and environmental safety, yet structural condition assessment remains bottlenecked by labor-intensive manual CCTV inspections. This thesis proposes a comprehensive algorithmic framework enabling fully autonomous, real-time deficiency detection, geometric assessment, and natural language reporting on resource- constrained edge computing platforms. Three core components address this challenge. First, RAPID-SCAN, a novel semantic segmentation architecture utilizing a Dynamic Feature Pyramid Network and Channel-Spatial Attention, achieves real-time, pixel-precise defect localization with dramatically reduced parameters. Second, an Edge-Optimized Vision-Language Model pipeline employing LoRA and 4-bit QLoRA quantization compresses Phi-3.5 for local deployment, en- abling autonomous technical …

The Role Of Floodplain Connectivity In Shaping The Abundance, Size-Class Distribution, And Schooling Behavior Of The Associated Fish Assemblage, Adam H. Quade

LSU New Orleans Theses and Dissertations

The life histories of many Louisiana fishes are closely tied to the timing, magnitude, and duration of the Mississippi River flood pulse, which regulates the ecological connectivity and productivity of adjacent floodplain habitats. Anthropogenic modifications such as levee construction and water-control structures have disrupted these natural hydrologic linkages, altering habitat quality and community structure across the Lower Mississippi River Basin. This dissertation used high-resolution imaging sonar to investigate how fish assemblages, species, and collectives respond to changes in floodplain connectivity within the Richard K. Yancey Wildlife Management Area prior to hydrologic restoration. In the first chapter, I applied imaging sonar …

The Unitary Executive And The Federal Reserve, Lev Menand

Faculty Scholarship

The U.S. Supreme Court may soon embrace an interpretation of the U.S. Constitution that would significantly expand the power of the president over federal administrators and invalidate key provisions in dozens of federal statutes. A critical question is whether this interpretation — known as the unitary executive theory (UET) — would also render unconstitutional central bank independence (CBI), an arrangement where a country’s monetary policy is formulated by a semiautonomous body of experts insulated from partisan political pressure. Several justices have suggested that it would not, and a growing scholarly literature has proposed ways for the Court to distinguish the …

Metrics Not Thresholds: How To Regulate Ai And Other Expert Methods For Use In Criminal Investigations And Proceedings, Rebecca Wexler

Faculty Scholarship

Should regulators set performance thresholds for AI tools used in the criminal legal system? This Article draws on U.S. evidence law for guidance. Its answer is ... don’t. Instead of gatekeeping with ex ante performance thresholds, regulators should require or incentivize metrics of reliability that can be clearly communicated to end-user decisionmakers.

Sticky Charters? The Surprisingly Tepid Embrace Of Officer-Protecting Waivers In Delaware, Jens Frankenreiter, Eric L. Talley

Faculty Scholarship

This article examines the response to Delaware’s much-heralded 2022 legal reform that permitted corporations, for the first time, to adopt charter provisions exculpating corporate officers from liability for breaching their fiduciary duty of care. Contrary to widespread predictions that corporate actors would swiftly adopt officer exculpation provisions, our analysis — using both traditional and generative artificial intelligence (AI) methods — reveals a surprisingly low rate of uptake, over three years after the reform’s enactment.

Our study makes both methodological and substantive contributions. Methodologically, we present a novel application of large language models (LLMs) to identify and interpret technical clauses in …

Effect Of Composition On Grain-Boundary Chemistry And Fracture Behavior In High-Entropy Carbides, Caleb Schenck, Marium Mostafiz Mou, Elizabeth Pritchett, Fu Yun Tsai, Josephine Hartmann, Michael Lastovich, Sam Daigle, Kayla Yano, Matthew J. Olszta, Sanjit Bhowick, Elizabeth Kautz, Gregory E. Hilmas, William G. Fahrenholtz, Donald W. Brenner

Materials Science and Engineering Faculty Research & Creative Works

High-entropy carbides (HECs) are often treated as a single material class defined by configurational entropy; however, their properties are governed by composition-specific defects and grain-boundary chemistry. This study demonstrates that substituting a single element can qualitatively change grain-boundary structure and fracture behavior in HEC ceramics. Two HECs, (Cr,Hf,Ta,Ti,Zr)C (HEC-Cr) and (Hf,Ta,Ti,W,Zr)C (HEC-W), were examined via electron microscopy, atom probe tomography, and molecular dynamics simulations. Simulations predict preferential segregation of Cr, W, and Zr to grain boundaries. Experiments confirmed Cr enrichment at grain boundaries and the formation of W-rich nanograins along boundary networks. Mechanical testing revealed that these compositional differences translated …

Evaluating The Integration Of Bio-Based Waste Into Cement Production: A Pathway To Sustainable Building, Anja Terzić, Suzana Filipović, Adriana Peleš Tadić, Jelena Živojinović, Ivana N. Jelić, Nina Obradović, William G. Fahrenholtz

Materials Science and Engineering Faculty Research & Creative Works

Rapid urbanization has increased the demand for building materials, depleting natural resources used in cement production and prompting the use of alternative and waste materials. This research verifies that eggshell powder waste can fully replace limestone in clinker synthesis. Five clinkers were produced using eggshell powder, aluminum sources (bentonite, zeolite, fly ash, and kaolinitic–illitic clay), Fe-slag, and quartz sand, with mechanical preprocessing (10–30 min) before sintering at 1300 °C. Experimental tests assessed the effects of mix design and mechanical activation on clinkerization, phase formation, temperature, and mechanical properties. XRD, FTIR, and SEM/EDS confirmed consistent phase compositions and primary cement minerals. …

Modeling Bicycle Ridership In Northwest Arkansas, Nelofar Qulizada

Graduate Theses and Dissertations

In a global comparison, the U.S. ranks second lowest in bicycle use for urban trips, surpassed only by Brazil. This underutilization signals missed opportunities to improve public health, environmental sustainability, and community connections. In Northwest Arkansas (NWA), a region actively investing in active transportation infrastructure, efforts were underway to reverse this trend. However, a key question remained: Were these investments effectively boosting bicycle ridership? To address this question, communities required reliable methods to measure cycling activity. Traditionally, this involved stationary counters placed at strategic locations to monitor ridership patterns. While accurate, these counters had limited spatial coverage. In contrast, emerging …

The increased usage of unmanned aircraft systems (UAS) for various applications has broadened access to high-resolution aerial imaging, a field with deep roots in geography, remote sensing, and geospatial science. Radiometric correction in satellite imagery has its origins in the early decades of Earth observation, with foundational work beginning alongside the launch of the first multispectral satellites and evolving through decades of research into atmospheric correction, sensor calibration, and reflectance modelling. As UAS adoption grows, research into atmospheric attenuation effects on UAS imagery becomes necessary. Empirical line calibration converts digital number values to surface reflectance and is used here to …

Design And Evaluation Of A Single-Gate Multi-Threshold Null Convention Logic Architecture For Area Efficiency, John Edward Swaim

Graduate Theses and Dissertations

Asynchronous circuit design paradigms, such as NULL convention logic (NCL) and Multi-Threshold NCL (MTNCL), offer increased energy efficiency over synchronous equivalents and robust pipelines with minimal timing analysis. However, their dependency on dual-rail signal encoding causes significant overhead compared to single-rail equivalents. Previous single-gate and single-rail NCL paradigms have sought to reduce circuit area, but most compromise their quasi-delay-insensitivity and correct-by-construction nature with logic gate and system-level design choices. This thesis presents Single-Gate MTNCL (SG-MTNCL), a register controlled, single-gate, and dual-rail asynchronous architecture to improve the area efficiency of MTNCL without compromising the reliability of previous paradigms. The benefits of …

Dutiful Wife, Grieving Mother: Examining Medieval Joban Allusion Through A Matricentric Affective Lens, Morgan Lee

Graduate Theses and Dissertations

This thesis uses concepts of matricentrism and affect to examine the legacy of Job and its frequent medieval allusions in stories featuring grieving mothers. It specifically analyzes how, in order to be considered noble, steadfast sufferers, women were expected to relinquish their maternal grief and adopt a stoic affect. This was often to the benefit of or in the direct service of their husbands. The analysis covers three women in particular: Job’s wife (who is examined through the medieval commentary written about her), Prudence from Chaucer’s "Tale of Melibee," and Griselda from Chaucer’s "Clerk’s Tale." This thesis utilizes medieval conduct …

Privacy Protection In Machine Learning: Methods For Structured And Unstructured Data, Karuna Bhaila

Graduate Theses and Dissertations

As machine learning models become increasingly integrated into data-driven decision-making, the protection of sensitive information throughout the model lifecycle is a paramount concern. As these models process and memorize sensitive, proprietary, or personal data, they risk leaking information through their outputs or internal states, especially in domains such as healthcare and finance. The protection of data in machine learning has thus been a crucial field of study. Within this paradigm, researchers have studied theoretical and application-oriented mechanisms for realizing privacy protections for various data formats. Nonetheless, privacy in machine learning still has many open problems, especially with the emergence of …

Efficient Deep Neural Networks For Autonomous Perception, Reeshad Khan

Graduate Theses and Dissertations

Autonomous perception systems must operate reliably under uncertainty arising from noisy observations, incomplete supervision, and hardware constraints. This dissertation investigates the design of efficient deep neural networks for autonomous perception through a unified perspective that treats uncertainty, efficiency, and sensing as interconnected challenges. The first contribution develops adaptive extensions of unbiased risk estimators, including eSURE and ePURE, enabling unsupervised training of deep neural networks for magnetic resonance image denoising under Gaussian and Poisson noise. However, these methods rely on known noise assumptions, which motivates the second contribution: a unified diffusion and Bayesian risk framework that estimates and adapts to unknown …

Misusing Mariátegui: The Strategic Use Of José Carlos Mariátegui By Peru’S Sendero Luminoso, Shaylee Luedders

Graduate Theses and Dissertations

The Peruvian Communist Party - Sendero Luminoso (SL) was a violent communist guerrilla group that was active in Peru in the 1980s and early 1990s. SL’s guiding ideology was “Gonzalo Thought,” named for the Party’s leader, Abimael Guzmán, who was known to his followers as Presidente Gonzalo. Greatly inspired by Marxism-Leninism-Maoism, Gonzalo Thought also drew heavily from the work of José Carlos Mariátegui, an early 20th-century socialist Peruvian intellectual. One of Mariategui’s key ideas held that the Inca Empire was communist and that living Indigenous Peruvians retained this pre-modern “communist spirit.” For him, this meant that authentic Peruvian institutions and …

Sedimentary Provenance Of The Pliocene – Pleistocene Giant Foresets Formation, Offshore Taranaki Basin, Aotearoa New Zealand, Anurag Kulkarrni

Graduate Theses and Dissertations

Sediment input and dispersal in the Taranaki Basin, offshore New Zealand’s North Island, was influenced by a complex interplay of ocean currents and sea level fluctuations over the late Neogene. This period of time was recorded in the Pliocene-Pleistocene Giant Foresets Formation (GFF) that represents a rapid progradation of the western continental shelf into the basin. High sedimentation rates during this time were likely a major contributing factor to the emplacement of multiple, large-scale (up to ~3,500 km3) mass-transport deposits (MTD) that were caused by shelf and slope collapse within the GFF of similar scale to that of the well-studied …

Developmental Mathematics As A Potential Barrier To Degree Completion In Community Colleges, Cynthia Bernice Fletcher

Graduate Theses and Dissertations

Developmental mathematics is often seen as a barrier to student progression in community colleges, especially for students pursuing Associate of Science degrees requiring math coursework. This quantitative, ex post facto, non-experimental study examined how developmental mathematics factors predicted Associate of Science degree completion at a two-year community college in the West South-Central United States. Specifically, it assessed how academic performance in developmental mathematics, placement method, math pathway, and number of developmental math courses related to Associate of Science degree completion, as well as differences across student subgroups. Archival institutional data were used for first-time-in-college students across four cohorts: 2018, 2019, …

Genre Prediction Using Rnns And Llm-Enhanced Video Game Review Data, Gabriel Young

Graduate Theses and Dissertations

LLMs (Large Language Models) are powerful tools for engaging with textual data, carrying many advantages over classical NLP (Natural Language Processing) and ML (Machine Learning) approaches. However, a classical ML model can still be faster, more efficient to run, and accessible than an LLM. We seek to gain the benefits of LLM text comprehension and preserve them in a classical ML model, a hybrid approach. The LLM operates on text to surface relevant information and associations in our problem space, then the ML model trains on the LLM output. The model may learn from the LLM and provide a more …

An Efficient Implementation Of Gibbs-Duhem Integration For Solid-Liquid Phase Coexistence In Binary Lennard-Jones System With Relevance To Aav Capsid Separation, Muhi Muntaka

Graduate Theses and Dissertations

Gene therapy using adeno-associated viruses (AAVs) holds promise for treating genetic diseases, but high manufacturing costs limit its widespread use. A major challenge is separating functional (full) AAV capsids from non-functional (empty) ones, which are produced in similar amounts and have nearly identical structures. Conventional purification methods, such as density gradient ultracentrifugation and chromatography, face drawbacks like low yield, poor scalability, and high cost, often requiring multi-step processes. Recently, selective crystallization has emerged as a promising alternative, offering improved efficiency, scalability, and product quality. However, optimizing this method requires a deep understanding of thermodynamic phase behavior in multicomponent systems. In …

Unveiling Factors Influencing Extract Yield From Milled Rice In Brewing, Matthew Aitkens

Graduate Theses and Dissertations

Rice (Oryza sativa L.) presents a locally sourced, climate-resistant starch source for the brewing industry. As barley faces increased uncertainty due to rising temperatures, Arkansas-grown rice offers a more stable and cost-effective alternative starch source. However, the use of milled adjunct rice by brewers has remained limited, largely due to knowledge gaps about cultivar-specific properties relative to brewing. Chapter 1 provides an overview of rice as a brewing adjunct, reviewing the physiochemical properties important to brewing success. These properties include kernel size, kernel breakage, amylose content, and gelatinization temperature. Mashing strategies for multiple different brewing layouts are overviewed, showing practical …

From Phenology To Yield Zones: Functional Clustering Of Satellite Time Series For Crop Growth Monitoring, Ikram Morso

Graduate Theses and Dissertations

Remote sensing and land surface phenology provide a strong basis for characterizing crop development, but their usefulness for within-field yield-zone delineation depends on whether crop development is analyzed as a phenological trajectory and whether the resulting zones are evaluated with spatially defensible statistics. These questions are especially relevant in soybean production because soybean is one of the most important row crops in the United States and the country’s dominant oilseed crop. This relevance is strong in Arkansas, where soybean is a major component of agricultural production. In soybean production, within-field yield variability reflects the combined influence of soil properties, stand …

Ꭰꮎꮰꭶ (Missing): A Phenomenological Study Of Native American Student Experiences In The Law School Setting, Christina Allene Shaw

Graduate Theses and Dissertations

The legal landscape for Native American people in the United States is ever evolving and highly nuanced, with its historical foundation anchored into the classical pilasters of American legal jurisprudence. Federal Indian law scholars place that historical foundation within the written opinions of Chief Justice Marshall dating back to the 1820s and 1830s (Fletcher, 2024). Although few law students will likely find themselves closely examining the unassigned readings of the Marshall Trilogy or contemporary federal Indian law, there is one small group of students in law school doing exactly that: Native American law students. American Indians and Alaska Natives are …

Coloniality Disrupted: Critical Knowledge Interventions Shift Decolonial Attitudes Among White Americans Via Collective Responsibility & Moral Outrage, Mejdy Jabr

Graduate Theses and Dissertations

Epistemologies of ignorance and critical knowledge dialectically shape how individuals psychologically and politically orient themselves within oppressive social systems. Across three studies, I investigated the psychological mechanisms through which critical-historical knowledge about Indigenous peoples relates to and causally shifts support for (or opposition to) decolonization among America’s foremost settler population, White Americans. Study 1 utilized an Indigenous history test to assess the relationship between critical knowledge and support for decolonization (i.e., decolonial policies and practices; DCPPs), finding that critical-historical knowledge is positively associated with DCPP support and that this relationship is mediated by collective responsibility. Studies 2 and 3 built …

Structural Relaxation In Glass-Forming Liquids At Extreme Pressure: Photon-Correlation Spectroscopy And Constrained Thermodynamic Surface Modeling, Kevin Wayne Lyon

Graduate Theses and Dissertations

Structural relaxation in glass-forming liquids is strongly dependent on both temperature and pressure, yet direct measurement of structural α-relaxation under multi-gigapascal compression has remained experimentally challenging. This work extends depolarized photon correlation spectroscopy (DPCS) to pressures approaching 5 GPa in a diamond anvil cell, representing the highest-pressure implementation of this technique and enabling direct measurement of the structural α-relaxation in a pure liquid at extreme compression. This capability provides access to dynamical regimes previously unexplored by photon correlation spectroscopy and establishes a platform for probing glassy dynamics at high pressure. To describe these measurements, a constrained relaxation-time surface framework is …

From Classroom To Courtroom: How Educational Strains Shape Juvenile Delinquency, Hailey Elizabeth Houston

Graduate Theses and Dissertations

Juvenile delinquency is a significant social issue with consequences that extend into adulthood and impact future success of youth. Although prior research has explored various factors that affect juvenile delinquency, notable gaps remain – notably a lack of literature on how educational strain effects juvenile delinquency with a focus on rural areas. This study addresses these gaps by examining the effects of educational strain, such as poor academic performance and lack of teacher support, on rural adolescents’ engagement in juvenile delinquency. Data for this study was obtained from the 2023 National Survey on Drug Use and Health (NSDUH), an online …
