The Statistical Distribution Of U.S. Corn And Soybean Futures Prices, Chiamaka D. Osigwe

LSU Master's Theses

This thesis investigates the best-fit empirical distribution for daily U.S. corn and soybean futures price changes and examines how distributional choices affect Value-at-Risk (VaR) and Expected Shortfall (ES) estimates. The dataset comprises daily nearby futures prices for corn (11/16/1994–04/23/2025) and soybeans (10/16/1979–02/15/2023), yielding 7,626 and 10,853 observations, respectively. An ARCH-LM test confirms the presence of Autoregressive Conditional Heteroskedasticity (ARCH). Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models were estimated, and to account for potential asymmetric effects, an EGARCH model was used. EGARCH (1,1) estimation reveals an inverse leverage effect, where positive price shocks generate higher volatility. Six heavy-tailed distributions were evaluated, and …

To Be Closer, Sarah Moschel Miller

LSU Master's Theses

to be closer explores the intersection of yearning and unease. This series of works uses the visual language of the body and its thresholds to explore how each of us builds interpersonal relationships and understandings of self. Pulling from abjection theory, the abject comes from the internal becoming external, the crossing of a bodily or personal threshold. My sculptures, vessels, and prints translate the visual language of the border of the body into a discussion of emotional ones. to be closer uses these corporeal thresholds and the language of the uncanny as vehicles to discuss the crossing of emotional …

Commissioning And Validation Of An Electron Treatment Planning System: Following Mppg.5.B Guidelines, Hailey N. Reaux

LSU Master's Theses

Methods: The eRT beam model was configured using commissioning data from an Elekta Infinity linear accelerator at Mary Bird Perkins Cancer Center (MBPCC). Validation measurements were performed for …

Distributed File Carving, Brad J. Baudin

LSU Master's Theses

File carving is a fundamental technique in the digital forensics community, enabling analysts to recover deleted files from disk images without relying on filesystem metadata; however, as storage capacities continue to increase, modern file carving tools face significant scalability challenges, with carving time growing substantially alongside disk image size, particularly in the presence of file fragmentation. Fragmentation, a common behavior in modern filesystems, distributes file data across non-contiguous disk blocks to maximize space utilization, and in large disk images this distribution can span wide logical distances, increasing the search space and reducing carving efficiency, causing traditional approaches to struggle within …

Building Early Reading Foundations In Prekindergarten: Preparing Students For Kindergarten, Denise Rueter, Laura K. Simmons, Cynthia Dicarlo

Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators

Preparing children for the transition to kindergarten literacy instruction requires intentional support of foundational early reading skills in prekindergarten classrooms. At the same time, early childhood educators must balance explicit instruction with developmentally appropriate practices (DAP) that emphasize play, exploration, and child-centered learning. This article describes instructional practices that support the development of emergent reading skills, particularly letter recognition and phoneme identification, within prekindergarten settings. Drawing on research in early literacy development, the article outlines a small-group instructional routine that includes shared storybook reading with print referencing, phonemic awareness activities, and multi-sensory, play-based practice opportunities. Examples of center-based activities that …

Building The Foundation For Stem In Toddler Classrooms: Practical Strategies For Novice Teachers, Melissa L. Johnson

Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators

Young children are natural explorers, and even in the toddler years, they demonstrate the inquiry behaviors foundational to later science, technology, engineering, and mathematics (STEM) learning. However, early STEM experiences are often underutilized in toddler classrooms, primarily due to misconceptions about children's capabilities and a lack of developmentally appropriate resources. This article, written for novice educators, offers practical strategies and examples to help integrate STEM into toddler classrooms. Drawing on current research, national standards, and classroom-based implementation strategies, this piece outlines how to create engaging environments that support toddlers' curiosity and emerging STEM thinking across science, technology, engineering and mathematics.

Techno-Economic Assessment And Life Cycle Analysis Of Electrocatalytic Reduction Of Co2 To Ethanol., Omotolani Elizabeth Oduyebo

LSU Master's Theses

This study presents a techno-economic analysis (TEA) and life cycle assessment (LCA) of the electrocatalytic reduction of CO₂ to ethanol, a multi-carbon (C₂) product with significant market value. Prior TEA studies have relied on simplified lump-sum separation cost estimates, and prior LCA studies have rarely examined the combined effect of CO₂ source and electricity supply on carbon intensity gaps that this work addresses through process-simulation-grounded analysis. An Aspen Plus process simulation was developed for an anion-exchange membrane (AEM) electrolyzer system coupled with an extractive distillation separation train using ethylene glycol as the entrainer, achieving 99.9 wt.% ethanol purity …

Models, Agency, And Expectations: A Mixed-Methods Study Of How Character Develops In Middle School, Aaron J. Schwindt

LSU Doctoral Dissertations

This explanatory sequential mixed-methods study investigated how character develops among middle school students at an international school recognized as a "National School of Character." Despite significant investment in character education (CE), a lack of formal evaluation exists, particularly regarding the process of development during the critical middle school years, a period of intense neurological and social change. Grounded in Bandura's Social Cognitive Theory (SCT), this study aimed to (1) understand how character develops, (2) compare development before and after program enhancements, and (3) assess the program's impact on discipline. Phase 1 collected Character Growth Index (CGI) survey data from students …

Within These Walls, Nicholas J. Roberts

LSU Master's Theses

I was raised to understand home through labor. In the working-class household I grew up in, in rural Southeastern Pennsylvania, value was earned through work, identity took shape through trade, and rest was often an afterthought. That framework was not chosen. It was inherited. And it has not been easy to see it clearly from the inside.

The Exhibition, Within These Walls, examines that inheritance through printmaking and sculpture, using the material and spatial language of domestic construction as both subject and method. Through fragile paper structures that resemble wood but cannot hold weight, a staircase that cannot be climbed, …

Silent No Longer: Pedro Albizu Campos And The Fbi, Noah D. Dubroff

LSU Master's Theses

This thesis explores the Puerto Rican revolutionary, Pedro Albizu Campos, and how he evolved from a typical independence-minded young man into a radical who actively rebelled against the colonial rule of the U.S. because of the pressures applied by law enforcement agencies, especially the Federal Bureau of Investigation.  The United States annexed Puerto Rico in 1898 at the conclusion of the Spanish-American War. Ever since, many Puerto Ricans have strongly advocated for their independence from the continental U.S., shaping the relationship into the present day. This article argues that the pressure and strain of such an imperial relationship influenced Albizu …

Climate Change Attributable Flooding And Post-Disaster Housing Market Dynamics: Evidence From Hurricane Harvey, Kaylynn Larrison

LSU Doctoral Dissertations

Climate change is increasing the frequency and severity of extreme weather events, yet the social consequences of climate change attributable impacts remain relatively underexplored. This dissertation examines whether flooding attributable to climate change was associated with distinct post-disaster recovery outcomes following Hurricane Harvey in Harris County, Texas. To explore this link, parcel-level flood model outputs are integrated with Harris County Appraisal District parcel data and OpenFEMA records on tract-level flood insurance policies and post-Harvey aid. Response variables are operationalized as change scores to capture differences between pre- and post-storm conditions and outcomes are measured over a five-year post-storm period. Across …

Momentum Space Algorithm For Electronic Structure Of Double-Incommensurate Trilayer Graphene, Kenneth Silver Beard

LSU Doctoral Dissertations

Numerical algorithms for computing the electronic structure of incommensurate 2D-materials using ab initio models are critical for predicting material properties and guiding experiments. For bilayers, momentum space and continuum models have been introduced to approximate observables of ab initio tight-binding models using a momentum description, despite the lack of periodicity in the tight-binding model required for Bloch theory. A similar structure has been introduced for double-incommensurate trilayers using a continuum model, where the three lattices are mutually incommensurate. However, this description leads to a four-dimensional lattice space, and numerical convergence of the density of states has been observed to be …

Greedy Algorithms And Matroids, Kiri M. Strack

LSU Master's Theses

In a connected graph with weights on the edges, a minimum-weight spanning tree can be obtained by repeatedly choosing minimum-weight edges while avoiding choosing the edge set of any cycle. This algorithm is known as Kruskal’s Algorithm, although it was first introduced by Boruvka in 1926. Prim introduced an alternative algorithm in which, at each step, the chosen set of edges forms a connected graph. Both of these algorithms make locally optimal choices that eventually yield a global optimum. This thesis considers how these algorithms can be extended to matroids. In particular, it is shown that matroids are exactly the …

Noncontingent Parental Attention Leads To Independent Play And Is Preferred By Toddlers Over Screen Time, Kristen Newell

LSU Doctoral Dissertations

Caregivers often rely on screen media to occupy young children during periods when caregiver attention is unavailable, despite evidence linking early screen exposure to adverse developmental outcomes. An alternative approach is to provide high-quality, noncontingent attention (NCA) during play prior to independent activity. Although NCA reduces attention-maintained challenging behavior, the optimal duration of NCA and children’s preference for caregiver interaction relative to screen time remain unclear. This study evaluated the effects of varying durations of caregiver-delivered NCA on young children’s independent play, attention-seeking behavior, and preference for NCA compared to screen time. Three caregiver–child dyads participated in a multielement design …

A 2 x 2-meter excavation was placed north of Building …

Comparing The Effects Of Suicide Stigma Reduction Interventions On Adult Help-Seeking Intentions: An Experimental Investigation, Max Stivers

LSU Master's Theses

With relatively few individuals who experience suicidal thoughts and/or behaviors (STB) engaging in formal treatment, one critical aspect of bridging the treatment gap is to reduce barriers to their seeking help (WHO, 2014). Stigma regarding suicide and mental health help-seeking has been identified as a barrier to care, inspiring development of interventions and public health campaigns targeting stigma reduction as a means of increasing help-seeking attitudes, intentions, and behavior (Corrigan et al., 2004). However, because efforts focusing specifically on reducing stigma may fail to address other logistical and psychosocial barriers to engaging with treatment, their broader impact in promoting help-seeking …

Analyzer-Less X-Ray Interferometry With Super-Resolution Methods, Murtuza S. Taqi

LSU Master's Theses

X-ray interferometry provides valuable information on attenuation, small-angle scattering, and differential phase contrast. This multi-modal contrast can aid in many clinical applications, such as lung diseases and breast cancer. However, standard inter- ferometry has an analyzer grating that can increase the dose requirement to maintain the same image quality as a standard X-ray. We propose the use of super-resolution methods for X-ray grating interferometry without an analyzer, with detectors that fail to meet the Nyquist sampling rate needed for traditional image recovery algorithms. Detector phase- steps are used to nominally recover the sampling and iteratively recover the visibility and the …

Recent Wetland Elevation Dynamics In Coastal Louisiana, Usa, Elizabeth Harris

LSU Master's Theses

Coastal marshes globally are increasingly vulnerable to accelerating relative sea-level rise (RSLR), which threatens their capacity to maintain elevation through feedbacks among sediment supply, vegetation productivity, hydrology, and soil processes. Although many marshes can persist under moderate rates of sea-level rise through vertical accretion and belowground biomass production, this resilience is strongly constrained by sediment availability and subsurface processes such as autocompaction and organic matter decomposition. High accretion is often assumed to confer marsh resilience; however, subsurface processes, particularly autocompaction driven by surface loading, can substantially offset elevation gains. Coastal Louisiana experiences among the highest rates of RSLR worldwide due …

Setbacks And Stigmas: The Career Consequences Of Mental Health Treatment For Soldiers In Combat Roles, Micah Mark Marchand

LSU Master's Theses

This study examines how potential career consequences, perceived stigma, and confidentiality concerns influence mental health help-seeking among United States Army Soldiers, with particular attention to differences across Military Occupational Specialty (MOS) categories. Despite the availability of behavioral health services, many service members delay or avoid treatment due to fears that seeking care may negatively impact their careers, including risks to promotion, deployment eligibility, and retention. Guided by Systems Theory, this research explores how interconnected military structures, policies, and cultural norms shape these perceptions and behaviors.

Using a confidential survey design, data were collected from current service members and recently separated …

Public Understanding Of Ai-Enabled Cyber Threats And Its Impact On Cybersecurity Governance In The United States, Charlotte M. Barbrick

LSU Master's Theses

Artificial intelligence is spreading quickly in workplaces and everyday life, and that fast growth is creating cybersecurity and privacy risks that current laws and organizational practices do not fully address. This thesis asks whether AI-specific knowledge shapes public support for cybersecurity governance of AI-enabled systems in the United States. Using nationally representative survey data from the Pew Research Center’s American Trends Panel (ATP) Wave 119, fielded December 12--18, 2022, I estimate weighted regression models to test how objective AI knowledge shapes support for cybersecurity governance. I also test whether concern about data misuse helps explain that relationship and whether AI …

The Right-To-Work Debate In Louisiana: How A Moment Of Violence Changed Law, Emma K. Thigpen

LSU Master's Theses

These two projects focus on the rise of business communities in twentieth century politics of the South and how they shaped national visions of the United States’ economic future. Chapter 1, a primary source project about how labor violence led to a Right-to-Work law, examines the actions of the La. AFL-CIO, led by Victor Bussie, and the Louisiana Association of Business and Industry, led by Edward Steimel, as they pursue alternate visions of economic progress and the “American way.” A major theme of this chapter is how violence was manipulated and refashioned to legitimize a lobbying organization and legislation intended …

The Effects Of Dietary Protein Manipulation On Operant Demand, Brianna R. Lilly

LSU Master's Theses

Previous work with dietary protein restriction in rodents has demonstrated that rodents fed a low protein diet exhibit physiological effects such as lower rates of weight gain and increased levels of circulating fibroblast growth factor 21 (FGF21). Dietary protein restriction also produces behavioral effects. Compared to rodents that are not protein-restricted, rodents that are protein-restricted exhibit increased food intake and higher preference for a protein vs. carbohydrate solution. Additionally, protein-restricted rodents will respond at higher levels for a protein reinforcer than non-restricted rodents. The current study assessed the effect of dietary protein restriction on operant protein demand during and after …

Implantable, Sensor-Embedded Vascular Graft Towards Wireless Monitoring Of Stenosis, Nnamdi Dike

LSU Master's Theses

Arteriovenous (AV) grafts are commonly used to provide vascular access for hemodialysis in patients with end-stage renal disease. Despite their widespread use, AV grafts are prone to complications such as stenosis and thrombosis. Early detection of these conditions remains challenging with current monitoring methods too costly or insufficient. This work presents the design, fabrication, and validation of an LC pressure sensor embedded within a model AV graft to enable real-time monitoring. The proposed system integrates a parallel-plate capacitive pressure sensor with a spiral inductor to form an LC circuit embedded within an elastomeric graft wall. The Ecoflex 00-30 dielectric layer …

Exploring Perspectives Of Autistic Individuals And Caregivers On Autism Inclusive Services In Public Libraries, Ayva J. Rose

LSU Master's Theses

Public libraries are increasingly recognized as important community hubs designed to promote literacy, learning, language, family engagement, and inclusivity. Despite this, autistic individuals may experience language, literacy, sensory, and social differences that could impact their ability to participate in literacy-based programming in libraries. Librarians currently report a desire to provide services that not only include but meaningfully support autistic children in their families; however, little research has examined how key stakeholders within the autism community perceive autism-inclusive programming within libraries. This research seeks to explore these perspectives and identify (1) perceived barriers to attending children’s library programs, (2) accommodations and …
