Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond
Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond
Distinguished Undergraduate Researcher Program
Over the course of embryonic development, the ectodermal cell layer gives rise to a vast array of neurons and glia patterned across the central nervous system (CNS). Neurulation and specification is achieved in the ectoderm through temporospatial patterns of transcription factor (TF) expression, many of which are conserved across evolutionary history. These conserved regulatory motifs allow the use of Drosophila melanogaster to study the mechanisms of neurodevelopment across the animal kingdom. The huckebein (hkb) gene encodes a conserved SP1/KLF TF known to play important roles in cell cycle regulation, tissue morphogenesis during tubular organ development, and gut specification in Drosophila. …
Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal
Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal
Distinguished Undergraduate Researcher Program
Historically, low insulin levels were the signaling event considered responsible for metabolic adaptations to starvation, such as increased sympathetic outflow and increased serum levels of ketones, glucagon, and free fatty acids. Leptin, a hormone produced by adipose tissue, is known to decrease in response to caloric restriction. Recent work in the field suggested that leptin infusion in the final hours of a 48-hour fast reversed all metabolic adaptations to starvation, thus raising questions about an underappreciated role of leptin in the starvation response. This study tested whether physiological leptin replacement, maintaining fed plasma leptin concentrations, during a 72-hour fast in …
Still A Boy’S Club: Women Journalists & Political News Coverage, Khaleel Oudraogo, Elise Strain
Still A Boy’S Club: Women Journalists & Political News Coverage, Khaleel Oudraogo, Elise Strain
Distinguished Undergraduate Researcher Program
We investigate the level of gender parity in political news reporting at the New York Times. We apply a media sociology approach to examine how gender stereotypes, women in media leadership, and women in political leadership interact to affect the extent to which women journalists appear in bylines about domestic and foreign affairs news. We leverage an original data collection of nearly 3,000 news articles published from 2007–2020. We find several key results. First, women are more likely to appear in bylines about domestic political news than foreign affairs news. Second, we find that during Jill Abramson’s tenure as executive …
Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman
Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman
Distinguished Undergraduate Researcher Program
The act of passing would seem to be the opposite of activism because it is an act meant to avoid detection. While the language of passing is, itself, problematic, African-descended people passing as white might be read as attempting to capitulate to a racial binary. Similarly, trans people passing as cis or cishet might be read as attempting to capitulate to the gender binary rather than challenging it. But this paper explores the potential for reading passing as a surprising act of activism that foregrounds resistance, resilience, and solidarity rather than disappearance. I focus on Leslie Feinberg’s groundbreaking trans novel …
Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes
Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes
Distinguished Undergraduate Researcher Program
Rapid urbanization is an ongoing challenge to the natural ecosystem across Louisiana as the state invests in development to accommodate the challenges of flooding in nearby towns and cities. Across Louisiana waterways, flooding from urban developments along with coastal subsidence and relative sea level rise increase the transport of complex organic matter into local water channels. These events lead to higher concentrations of nutrients, specifically bioavailable carbon which can be lost from breakdown of soil organic matter in water. To better understand and predict organic matter transportation due to flooding events caused by urbanization, we studied the availability of organic …
Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim
Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim
Distinguished Undergraduate Researcher Program
Plastic pollution in aquatic environments has increased, raising concerns about the toxicity of microplastics (MPs) and their additives to developing organisms. Additives from the MPs can desorb into the surrounding environment, generating leachates that may impact early development. This study evaluated the effects of early developmental exposure to MP leachates on early developing zebrafish (Danio rerio), quantifying effects on larval survival, development, activity, and behavioral responses to acute stressors. MPs—acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyamide 66 (PA66), and reinforced glass fiber (MIX)—were processed into particles (< 500 µm) and incubated in embryo media for 24 hours under UV-C, 35 °C, and agitation to generate leachates. Zebrafish embryos were exposed from 6 to 120 hours post-fertilization (hpf) to varying leachate dilutions (corresponding to 0.063 to 10,000 mg MPs/L). At 120 hpf, larvae were assessed for survival, prevalence of morphological defects, overall growth, baseline activity, and behavioral responses to acoustic, visual, and peripheral irritant stressors. MIX leachate significantly increased mortality, while PET leachate exposure reduced growth. No significant morphological defects were observed across treatments. ABS, PA66, and PET leachates altered larval activity and behavioral stress responses. These preliminary findings suggest that MP leachates pose varying developmental and behavioral risks to developing organisms at critical exposure concentrations. Understanding these risks is crucial for assessing the environmental impact of MPs pollution and informing regulatory policies.
Semantic Control In The Prefrontal Cortex: An Ale Meta-Analysis, Francesca Thomassee, Christopher Cox
Semantic Control In The Prefrontal Cortex: An Ale Meta-Analysis, Francesca Thomassee, Christopher Cox
Distinguished Undergraduate Researcher Program
Semantic control is the ability to manage our knowledge about the world to ensure that the information produced is appropriate to a given context (Lamdon Ralph et al., 2017). While the left inferior frontal gyrus (LIFG) has been found to be significantly involved in semantic control (Jackson, 2021), it remains unclear if there is a region of the LIFG that is specific to semantic control and is not involved in any other executive tasks. To investigate this, we employed an activation likelihood estimate (ALE) meta-analysis of prior PET and fMRI research including strong-weak association and feature selection tasks. Based on …
Bird Diy: Building An Rfid System To Study Behavior In Free-Living Starlings, Raedan Stephens, Keegan Stansberry, Christine Lattin
Bird Diy: Building An Rfid System To Study Behavior In Free-Living Starlings, Raedan Stephens, Keegan Stansberry, Christine Lattin
Distinguished Undergraduate Researcher Program
Radio Frequency Identification (RFID) technology can be effectively utilized to gain insights into animal behavior, such as avian responses to environmental change. In our established field system of free-living European starlings (Sturnus vulgaris), we sought to implement a new system of RFID readers with antennas encircling the entrances of bird boxes and RFID leg bands with unique identifiers that record when birds pass through the antennas. To limit costs, we used Arduino RFID readers built by Eli Bridge and Jay Wilhelm and constructed the rest of the system components ourselves. We designed and 3D printed a new device to efficiently …
Imposter Syndrome And Coping-Motivated Cannabis Use: The Impact Of Race, Lan Qiu, Katharine Thomas, Julia Buckner
Imposter Syndrome And Coping-Motivated Cannabis Use: The Impact Of Race, Lan Qiu, Katharine Thomas, Julia Buckner
Distinguished Undergraduate Researcher Program
Cannabis use among college students has become increasingly prevalent, with coping being
one of the primary motives for use. Imposter syndrome, characterized by persistent self-doubt
and fear of being exposed as a fraud despite evidence of competence, is particularly common
among students. Given its association to social anxiety and social anxiety’s relation to coping
motives and cannabis-related problems, imposter syndrome may contribute to coping-motivated
cannabis use and related problems. Yet, no known research has examined the impact of race
on the relation of imposter syndrome and cannabis use behaviors among Black and non-
Hispanic/Latine White students. The current sample included …
Bayou Bride: Combining Alligator Leather And Digital Textile Printing In Bridalwear, Martha Rigney, Casey Stannard
Bayou Bride: Combining Alligator Leather And Digital Textile Printing In Bridalwear, Martha Rigney, Casey Stannard
Distinguished Undergraduate Researcher Program
Alligator leather is attractive to luxury consumers because of its unique texture and beauty. However, due to the shape of alligator hides, differing scale patterns, and the hardness of the leather, it is less appealing for usage in apparel. One strategy to retain the visual appeal of alligator leather while improving comfort and versatility is to create photo-realistic digitally printed “alligator” textiles alongside real leather. Discovering new ways to use alligators is crucial to the alligator industry, which is experiencing a price slump. This project focused on the bridal market; the utilization of sublimation dye printing allowed me to experiment …
Memory For Everyday Chores In Younger And Older Adults, Cameron Mccleary, Katie Cherry
Memory For Everyday Chores In Younger And Older Adults, Cameron Mccleary, Katie Cherry
Distinguished Undergraduate Researcher Program
This study examined episodic memory performance for everyday household chores in younger (18-32 years) and older adults (65-79 years). With the increasing older adult population in the United States, understanding age-related memory differences and identifying strategies to enhance memory performance in later life is needed. Building on previous research demonstrating the pictorial superiority effect and benefits of semantic encoding across the adult lifespan, this study utilized a 2 × 2 × 2 between-groups factorial design to investigate the effects of age group (younger, older), encoding task (standard intentional learning, semantic elaboration), and stimulus format (text only, text with pictorial illustrations) …
Relearning Language: A Meta-Analysis Of Syntactic Priming In Aphasia, Ally Miller, Willem Van Boxtel
Relearning Language: A Meta-Analysis Of Syntactic Priming In Aphasia, Ally Miller, Willem Van Boxtel
Distinguished Undergraduate Researcher Program
Background: Despite the importance of grammatical skills for participation
in daily life, treatments for sentence–level abilities in aphasia
are comparatively scarce. The psycholinguistic paradigm of syntactic
priming has recently been advanced as a potential assessment and
treatment for grammatical skills, and existing evidence on priming in
aphasia is highly promising. Nevertheless, a comprehensive analysis of
the strength of priming effects in aphasia, as well as treatment components
which might amplify these effects, has not been reported.
This meta–analysis synthesizes existing findings on syntactic priming
in aphasia, aiming to provide a comprehensive picture of priming
effects and their potential application for …
Motor Planning And Execution During Feeding In Autistic Children, Iresa Lincoln
Motor Planning And Execution During Feeding In Autistic Children, Iresa Lincoln
Distinguished Undergraduate Researcher Program
Autism is one of the most common pediatric developmental disability diagnoses, diagnosed in approximately 1 in 31 children in the U.S. and 1 in 100 children globally. Autism is often characterized by differences in social communication and repetitive patterns of behavior, activities,
or interests; however, prevalence of clinically significant motor differences in autistic individuals is between 50-95%. These motor differences often interfere with activities of daily living and community participation. Research assessing motor control in autism has yielded mixed findings as to whether the motor differences observed in autistic individuals are associated with differences in motor planning or motor execution. …

Evaluation Of Liberty® Herbicide For Zygosity Verification In Transgenic Maize (Zea Mays) Expressing The Bar Gene From Streptomyces Hygroscopicus, Isabel Hau
Distinguished Undergraduate Researcher Program
Maize (Zea mays) is a major global crop cultivated for food and feed. Most commercial varieties grown in the United States contain herbicide-resistant traits to facilitate weed management. One such herbicide trait is Liberty-Link, which contains the bialaphos resistance (bar) gene from Streptomyces hygroscopicus that confers resistance to glufosinate-ammonium, the active
ingredient in Liberty herbicide. This bar gene is also widely used as a selectable marker in plant transformation. In non-transgenic plants, glufosinate-ammonium inhibits plant glutamine synthetase by acting as a glutamate analog, thereby disrupting amino acid biosynthesis and leading
to plant death. In contrast, transgenic plants expressing the bar …

From Millionaires To Marsh Island: Origin And Development Of Wetland Conservation Efforts In Louisiana, Roan Guidry
Distinguished Undergraduate Researcher Program
Wetlands are protected, managed, and restored worldwide to provide a range of ecosystem services, including (i) habitat for plants and animals, (ii) carbon storage, (iii) improving downstream water quality, and (iv) reducing flooding by river and coastal waters. When did such conservation begin, and how do early conservation efforts shape recent public policy? This thesis identifies some of the earliest recorded examples of private efforts in Louisiana and analyzes how these early efforts shaped State and Federal Government action in the realm of conservation. The earliest wetland protection efforts in Louisiana began in the 1910s to sustain continental populations of …
Analyzing And Understanding America’S Involvement In The Global War In Terror Through The Oral Histories Of Its Veterans And Other Sources, Bryce Edwards
Distinguished Undergraduate Researcher Program
From 2001 to the early 2020s, the United States and its allies have consistently engaged in political, military, counterinsurgency, and nation building operations in nations such as Afghanistan and Iraq. The efforts of this coalition first rallied to combat the threat of global terrorism after September 11th, yet it would then develop in decades-long assignment to rebuild these countries and their institutions with fundamental (and foreign) western values. This thesis intends to examine the conflict by conducting oral histories of its many veterans, to better understand their lived experience. These interviews will be supported by scholarly works from those involved …
Droplet Microfluidics Integrated With Machine Learning Reveals How Adipose-Derived Stem Cells Modulate Endocrine Response And Tumor Heterogeneity In Er+ Breast Cancer, Calley Chauvin, Braulio Andres Ortega Quesada, Elizabeth Martin, Adam Melvin
Droplet Microfluidics Integrated With Machine Learning Reveals How Adipose-Derived Stem Cells Modulate Endocrine Response And Tumor Heterogeneity In Er+ Breast Cancer, Calley Chauvin, Braulio Andres Ortega Quesada, Elizabeth Martin, Adam Melvin
Distinguished Undergraduate Researcher Program
Approximately 70% of breast cancer (BC) diagnoses are estrogen receptor positive (ER+) with ∼40% of ER+ BC patients presenting de novo resistance to endocrine therapy (ET). Recent studies identify the tumor microenvironment (TME) as having a key role in endocrine resistance in which adipose-derived stem cells (ASCs) play an essential role in cancer progression. Prior studies have indicated that ASC characteristics such as age and BMI may play a role in cancer progression. Unfortunately, most studies on ASC-BC cross talk have relied on established two-dimensional (2D) culture systems or the use of conditioned media that cannot replicate the complexity of …

Incorporating family engagement into preschool programs is not merely beneficial but essential for promoting holistic child development in programs where children feel safe, cared for, and secure. In this article, we share the benefits of effective family engagement activities for families with young children and describe how we celebrated the National Association for the Education of Young Children's 2025 Week of the Young Child.
Understanding And Supporting Sustained Attention In Young Children: What Research Tells Us About Choice, Play, And Teaching Conditions, Cynthia F. Dicarlo, Carrie L. Ota
Understanding And Supporting Sustained Attention In Young Children: What Research Tells Us About Choice, Play, And Teaching Conditions, Cynthia F. Dicarlo, Carrie L. Ota
Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators
This article examines how sustained attention develops in young children and how different teaching conditions influence engagement during play. Drawing on studies with two-, three-, and four-year-olds, the findings show a developmental progression in which toddlers benefit from limited, adult-guided choices, while preschoolers sustain attention best when given autonomy to select their own materials. The article highlights how play, intentional choice-making, and age-appropriate scaffolding support children’s emerging self-regulation and engagement. Practical strategies are provided to help teachers design environments and interactions that promote deeper focus and independent learning.

Nonlinear Proudman Resonance Under Moving Atmospheric System, Chunyan Li
Nonlinear Proudman Resonance Under Moving Atmospheric System, Chunyan Li
Faculty Publications
A nonlinear theoretical model with an exact solution is developed to critically examine the Proudman resonance problem. In this framework, a moving atmospheric pressure system forces a wave governed by the square of the wave Froude number (n=F2). Proudman’s classical linear solution, although widely cited, diverges to infinity at resonance (n=1), limiting its physical realism. This work extends the linear regime into the nonlinear by solving the governing equations exactly. The resulting solution remains finite at resonance. The first-order approximation recovers Proudman’s solution, while the second-order approximation already yields a finite resonant response—providing a more accurate and physically …
Cultural Synthesis In Iranian Graphic Design: A Fusion Of Tradition And Modernity, Maryam Mehrabadi
Cultural Synthesis In Iranian Graphic Design: A Fusion Of Tradition And Modernity, Maryam Mehrabadi
LSU Doctoral Dissertations
This thesis examines Iranian graphic design as a politically embedded and semiotically charged field wherein visual form operates as a site of ideological negotiation, cultural memory, and symbolic resistance. Focusing on the works of Ghobad Shiva and Morteza Momayez, the study situates graphic design within the sociopolitical constraints of the Pahlavi monarchy and the post-1979 Islamic Republic. It argues that Iranian design practices cannot be understood outside the country’s enduring identity crisis—shaped by the unresolved tension between three coexisting cultural strata: ancient Persian heritage, Islamic civilizational identity, and Western modernity. Drawing on the work of Edward Said, the thesis also …
