Transcription Factors Daf-16/Foxo And Hlh-30/Tfeb Form A Regulatory Axis To Control Tubular Lsysosomes Formation In C. Elegans, Cristian Ricaurte

LSU Doctoral Dissertations

The development of therapies that can be applied in human health care to promote longer and healthier lives is one of the main goals of aging research. However, many of the interventions currently available have serious adverse effects that limit their translational potential. Thus, new strategies are urgently needed to promote healthy aging in humans. Here, we reveal a functional interaction between the insulin signaling pathway and mTOR pathway that promotes healthy aging in C. elegans via lysosomal tubulation. Their respective transcription factors, DAF-16/FOXO and HLH-30/TFEB cooperate, to drive the formation of tubular lysosomes (TLs) under various contexts, which contributes …

Quantifying And Integrating Community Hardship Into Two-Stage Stochastic Grid Reliability Optimization With Battery Storage, Fredrica Arthur

LSU Master's Theses

Traditional reliability planning for conventional distribution systems is largely utility-oriented, with a focus on collective system performance metrics like Expected Energy Not Supplied (EENS), where implicitly all unserved energy is considered of equal weight in terms of post-outage economic hardship. Yet, it is well understood that extended outage durations cause an uneven level of hardship to socioeconomically disadvantaged communities. This thesis proposes a community-informed reliability planning framework where the hardship caused by outages is explicitly considered in the battery energy storage system (BESS) location and sizing problem. First, a hardship-weighted Energy Not Supplied (WENS) measure is proposed, where income, education, …

Time-Robust Evaluation For Multi-Dataset Intrusion Detection Reveals Temporal Shortcuts And Strong Baselines, Kyle A. Mccleary

LSU Master's Theses

Pooled multi-dataset benchmarks are an attractive way to evaluate intrusion detection systems (IDS) across heterogeneous public corpora, but they can quietly reward shortcut features tied to capture schedules and dataset identity. This work introduces TRACER, an auditable benchmark specification that standardizes seven public IDS corpora into a shared transaction-window prediction unit and a shared label ontology, enabling controlled comparisons between compact sequence backbones and strong tabular baselines under matched splits, training budgets, and scoring rules.

Under this protocol, absolute clock time is a strong shortcut under pooled random splits. Enforcing time-robust controls (timestamp rebasing, circular shifts, and schedule-token masking) reduces …

Evaluating Eastern Wild Turkey (Meleagris Gallopavo Silvestris) Behavioral Ecology In The Southeastern United States, Chad Argabright

LSU Doctoral Dissertations

The wild turkey (Meleagris gallopavo spp.) is a game bird species in North America who are one of the great success stories in restoration and conservation. Wild turkeys were extirpated from most of their range in the early 20th century, but through habitat restoration and translocation efforts the population was restored to the point of being sustainably harvested in 49 U.S. States by the late 20th century. However recent declines in wild turkey population indices have necessitated ongoing research on the behavioral ecology of wild turkeys to help counteract these declines. East Texas specifically for the past century has …

Biogeochemical Controls On Phosphorus Transport And Legacy Storage Across A Coastal Watershed, Lee Potter

LSU Doctoral Dissertations

Excess phosphorus (P) loading is a key driver of eutrophication and harmful algal blooms (HABs) in aquatic systems worldwide. This relationship is of increasing concern in coastal Louisiana, where climate variability, altered hydrology, and land-use change converge, resulting in increased hydrologic and nutrient loading into coastal systems. This dissertation examines controls on P cycling in the Lake Pontchartrain Basin through a multi-scale framework linking estuarine processes, watershed loading, climate and weather patterns, and sediment dynamics. The dissertation begins with an overview of the study region, P dynamics, and changes in hydrology and nutrient loading patterns. Chapter 2 presents a spatial …

Engaging Underrepresented 11- To 14-Year-Olds In Music: An Autoethnographic Case Study Of A New Inner-City Afterschool Group Piano Program, Eden A. Brown

LSU Doctoral Dissertations

Research in music education has documented the underrepresentation of Black students in formal music study in the United States, shaped by economic and cultural barriers (Elpus & Abril, 2024; Alegrado & Winsler, 2020). Access to piano instruction is often limited by the high cost of lessons and instruments, inequitable school funding, and the absence of culturally responsive curricula that reflect the experiences of minority students and families. Traditional piano pedagogy rarely addresses this absence, leaving the piano both symbolically and practically distant for many potential musicians in the United States. This autoethnographic case study chronicles the development, launch, and first …

"By The Sweat Of His Brow"?: Master Mechanics And Class Position In Antebellum New Orleans, Caleb G. Roark

LSU Master's Theses

This thesis argues that New Orleans’s skilled laborers profited alongside or from enslaved laborers. Proponents of free labor ideology, largely relegated to the North, charged that the skilled mechanic was the prototypical “free laborer.” In contemporary and modern portrayals, the systems of free and enslaved labor were considered antithetical. This thesis posits that these views are incorrect. Free and enslaved labor flourished together in the Crescent City. Despite their absence in historical understandings of the antebellum South, skilled laborers succeeded in New Orleans. I track societal debates across Louisiana’s newspapers concerning the status and success of mechanics across the state. …

An Examination Of Trends And Factors Influencing Teen Retention In 4-H Youth Development Program: A Case Study, Bethany R. Corona

LSU Master's Theses

Teen participation in 4-H has declined nationally in recent years, raising concerns about long-term program sustainability and youth engagement. Understanding the factors that influence teens’ decisions to remain involved in 4-H is critical for informing program design and delivery. Guided by the theory of planned behavior, this qualitative study explored teen perceptions of 4-H programming, youth voice, social influences, communication, and barriers to participation. Data were collected through two group interviews with teen 4-H members representing multiple parishes. Interviews were audio recorded, transcribed verbatim, and analyzed using the constant comparative method through a three-phase coding process consisting of open, axial, …

Developments Of New Metal-Free Batteries And Self-Charging Batteries For Sustainability, Abhishek Paudel

LSU Doctoral Dissertations

The growing concerns over the limitations and environmental impact of conventional lithium-ion batteries (LIBs) have driven the search for more sustainable energy storage solutions. Metal-free batteries, such as those utilizing ammonium ions (NH₄⁺), offer a compelling alternative due to their non-toxic nature, abundant availability, and unique electrochemical properties. The NH₄⁺ ion's lower molar mass and distinct tetrahedral structure enable efficient charge transfer and intercalation, distinguishing it from traditional metal ions and potentially improving battery performance. Self-charging batteries, which integrate piezoelectric materials to harvest ambient mechanical energy, present a significant advancement in energy storage technology. By capturing and converting mechanical energy …

Dynamical Analysis Of A Stochastic $Sei_{U}I_{R}Rs$ Epidemic Model With Vaccination And Log-Normal Ornstein-Uhlenbeck Process, Qun Liu

Faculty Publications

In this study, we develop and investigate a stochastic $SEI_{u}I_{r}RS$ (Susceptible-Exposed-Undetected infected-Detected infected-Recovered-Susceptible) epidemic model with vaccination of newborns and the disease transmission rate driven by a log-normal Ornstein-Uhlenbeck process. By establishing a series of Lyapunov functions, we derive sufficient conditions for persistence in the mean of the disease in the long term under the condition $\mathcal{R}_{0}>1$ and these criteria are applied to guarantee the existence of an invariant probability measure of the stochastic system. Subsequently, we also derive sufficient conditions for eradication of the disease when the parameters $\mathcal{R}_{0}< 1$ and $\mathcal{R}_{0}^{E}< 1$. Finally, two numerical examples are given to confirm the theoretical results. This work can help us implement interventions to regulate the disease dynamics.

A Qualitative Examination Of The Motivations For Homeschooling Among Black Americans, Portia J. Witt

LSU Doctoral Dissertations

This qualitative phenomenological study explored the motivations and lived experiences of African American homeschooling families. Twelve Black parents from multiple states participated in semi-structured interviews. Data were analyzed using Moustakas’ (1994) Modified Stevick–Colaizzi–Keen method and coded thematically using NVivo. Nine themes emerged: autonomy, holistic education, community belonging, online networks, public resources, curriculum gaps, personal values, effective learning, and legacy of harm. While racialization in schools—including tracking, microaggressions, and misidentification—contributed to participants’ decisions, motivations also reflected intersectional factors such as faith, disability, mental health needs, giftedness, and a desire for cultural protection and flexible learning. Findings suggest homeschooling serves as a …

Effects Of A Group Contingency Arrangement Of Synchronous Reinforcement On Disruptive Behavior In Elementary Classes, Gabriela Gomes

LSU Master's Theses

Synchronous schedules of reinforcement are a type of schedule of covarion in which the onset and offset of the response are aligned with the onset and offset of the reinforcer. In this study, we used multiple baseline across classes and reversal designs to determine the effects of a synchronous reinforcement schedule, arranged as a group contingency, on disruptive classroom behavior and time spent following rules during independent work periods in three elementary classrooms: 2 first grade and 1 fourth grade. Additionally, we compared the effects of a synchronous reinforcement schedule with a continuous noncontingent schedule in the fourth-grade classroom. The …

Improving Stem Assessments: Strategies For Increasing The Accessibility And Adoption Of Two-Stage Exams, Kristina Callaghan

LSU Doctoral Dissertations

Over three decades of research have shown that students taught using active learning strategies achieve better learning outcomes compared to those taught using traditional methods. Two-stage exams, which pair a traditional exam with a group component, are an increasingly popular method for incorporating active learning within the assessment component of a course. Previous studies have shown this assessment strategy provides a variety of benefits for students, including increased engagement and collaboration, immediate feedback, and potentially increased content retention. However, the unique circumstances of each instructor can pose a non-trivial barrier to the implementation of two-stage exams. In this thesis, we …

Legacy Phosphorus Dynamics In Subtropical River Sediments: Impacts Of Dredging And Water Column Aeration Status, Lee Potter, John R. White

Faculty Publications

Excessive loading of phosphorus (P) in coastal systems has been a growing concern for watershed managers due to the link with harmful algal blooms. In particular, legacy P creates a persistent challenge for eutrophication management in a range of aquatic systems, including wetlands, lakes, and estuaries, as a source of indirect, internal P loading. Following reductions in external P loads, internal sediment sources have been known to release bioavailable P back into the water column, undermining nutrient restoration goals. This study investigates the flux dynamics and longevity of sediment legacy P in three subtropical rivers—Amite, Tangipahoa, and Tickfaw—draining into the …

Increasing Wave Heights In The Gulf Of Mexico Driven By Swell Waves, Jesbin George, Matthew Hiatt, Clinton S. Willson

Faculty Publications

This study analyzes the climatology, spatial and temporal trends of wind speeds and significant wave height (Hs) of combined wind-seas and swells and Hs of separated swells and wind-seas on annual and seasonal scales in the Gulf of Mexico (GoM) using 50 years of atmospheric reanalysis data. The Hs data showed strong agreement with in-situ measurements, with minimal bias (+/-< 0.08 m) and high correlation (r > 0.9) across both deep and shallow regions, although a slight underestimation is noted for wind speed data. Wind speeds showed seasonal variability in the GoM, though they did not exhibit significant long-term increases, except for a notable decrease (~ -1.0 …

Rosenwald Rural School Libraries, Suzanne Marie Stauffer

Faculty Publications

The Rosenwald Rural School Libraries Program was created as an adjunct to the Rosenwald Rural Schools Program, which funded the construction of 4,977 rural Black school buildings in fifteen Southern states, 395 of them in Louisiana. However, it soon became apparent that providing textbooks was not enough to promote literacy and develop self-directed reading among students. The officers and agents of the Fund realized fairly early in the Rural Schools Program that there was a want of reading materials in the South in general. Beginning in 1927, the Rosenwald Fund began providing collections of graded fiction and non-fiction books to …

Understanding The Diagenetic History Of Vertebrate Teeth From A Key Permian Ecosystem, Anthony Chiasson

Distinguished Undergraduate Researcher Program

Rare earth elements (REE) have been recognized within the last decade as important markers of diagenetic activity in fossil apatite. However, little work has been done to explore the influence of diagenesis on bioapatite in continental red bed settings. This study analyzed the REE preserved in a set of preserved Dimetrodon and Eryops teeth from the Clear Fork Formation, a set of Permian red beds near Seymour, Texas. Both Electron Probe Micro-Analysis (EPMA) and Laser-Ablation – Inductively-Coupled Plasma – Mass Spectrometry (LA-ICP-MS) were used to identify the constituent elements of the teeth. Chemical data from the EPMA indicate that the …

Bragging Rights: How Women Candidates Use Endorsements In Strategic Messages, Eva Carter, Tyhlar Holliway

Distinguished Undergraduate Researcher Program

This research analyzes the methods and terminology employed by men and women candidates when they talk about their political endorsements in strategic campaign communication. While existing literature addresses topics such as educating uninformed voters, the influence of endorsements in political campaigns, messaging ethics, celebrity endorsements, and the correlation between money and endorsements, analyses of gender differences in the use and types of endorsements remain underdeveloped. We argue that women candidates, due to the unique vulnerabilities they face in campaigns (Bauer 2015; Lazarus and Steigerwaltz 2018), will be more likely than men to highlight their endorsements in campaign ads. We record …
