Social Stories To Shape Impulsive Behaviors To Increase Self-Regulation In Preschoolers, Caroline Claire Hargrave

LSU Master's Theses

ABSTRACT

BACKGROUND: Students need to be able to self-regulate their behavior within the classroom, thus not interrupting instruction and keeping the classroom running smoothly. Self-regulation is a critical skill children need to succeed in multiple aspects of life. Poor self-regulation skills can lead to challenges academically as well as socially. Contrary to self-regulation is impulsivity, which surrounds not thinking before doing. Impulsivity is a common factor seen within the preschool setting, which surrounds multiple behavior variations deemed unsuitable for classroom learning. Previous research indicates that social stories can be implemented within the classroom to decrease inappropriate behaviors in preschoolers with …

Impact Of Glufosinate On Sugarcane Yield And Yield Components When Applied Post-Directed And Its Efficacy In Controlling Emerged Itchgrass (Rottboellia Cochinchinensis), Warner R. Simon

LSU Master's Theses

Weed control is extremely important in the Louisiana sugarcane (Saccharum spp.) industry, as it is a perennial crop that grows back after each harvest. Fields are kept weed free using mechanical and chemical methods to prevent weed-crop competition and further establishment of weed populations. The weed itchgrass (Rottboellia cochinchinensis) has become problematic for Louisiana sugarcane producers. Sometimes, itchgrass can still emerge after farmers have made a pre-emergence (PRE) herbicide application. These weeds are usually controlled using the herbicide paraquat dichloride (paraquat) in post-emergence (POST) directed applications. In recent year, 2016-2024, the United States Environmental Protection Agency …

The Design, Construction, And Testing Of Mrna Vaccine Against Equine Herpes Virus, Bhawana Devkota

LSU Master's Theses

Equine Herpesvirus-1 (EHV 1) is a worldwide significant pathogen that causes respiratory illness, abortion, and neurological disorders in equine. Current vaccines, including live attenuated, inactivated, and subunit platforms, do not prevent viral latency, mucosal shedding, or cross-strain immunity, requiring alternative approaches. To address these gaps, this project explores the design, synthesis, and in vitro testing of an mRNA vaccine targeting immunogenic EHV 1 glycoprotein (gB, gC, gD, gG, and gM). Epitopes were computationally predicted using the Immune Epitope Database (IEDB), codon-optimized for Bos taurus, and cloned into pUCIDT vectors using SP6/T7 promoters. In vitro transcription (IVT) used nucleotide modifications …

Desired Student Learning Outcomes For Middle School Agricultural Education: A Modified Delphi Study, Jacob P. Englin

LSU Doctoral Dissertations

Middle school agricultural education programs across the U.S. have continued to increase, but modern systems have failed to provide support for the preparation of middle school agricultural education teachers. For instance, middle school teachers have expressed concern regarding the development and implementation of middle school agricultural curriculum. In response, this investigation sought to identify learning outcomes related to agricultural content, technical skills, and career readiness for middle school agricultural education. A modified, three-round modified Delphi study was used to identify these learning outcomes. The expert panelists consisted of 19 middle school agricultural education teachers who completed a teacher certification program …

Variation In Response To Phosphorus Among Sweetpotato (Ipomoea Batatas L.) Cultivars, Jeffrey Cole Denis Gregorie

LSU Doctoral Dissertations

Phosphorus (P) is essential for plant growth and is often a major limiting nutrient in agriculture. In sweetpotato (Ipomoea batatas), studies on the role of P on storage root yield have been limited because of the lack of response and inconsistent results across cultivars and years. Growing evidence shows that current phosphate (Pi) fertilizer rates can be reduced while maintaining productivity. Newly published molecular evidence shows differential expression of phosphate starvation response genes among sweetpotato cultivars, further supporting the hypothesis of cultivar-specific Pi sensitivity. The research herein sought to characterize root system architecture and yield response to Pi …

The Metaphysics Of Frank Herbert's Dune And God Emperor Of Dune: On Time And Language, Garrett J. Busshart

LSU Doctoral Dissertations

This dissertation studies the metaphysics of time and rhetoric in the science fiction novels Dune (1963) and God Emperor of Dune (1981) by Frank Herbert. The first chapter critiques the protagonist’s sense of temporality, an ideology in which the future consists of multiple possible choices while each decision of one forecloses a still larger set. Jean-Pierre Dupuy calls this a “supermarket” model of temporality, as if the future were a contingent-free menu of possibilities a subject is free to pick between. My assertion is that this sense of temporality—the Western norm—matches the protagonist’s, Paul Atreides’s, rhetoric. In disclosing Paul’s sense …

Investigating Spatial Mapping Of Lipid And Protein Alterations Within Cells And Tissues Using Raman Microspectroscopy, Elnaz Sheikh

LSU Doctoral Dissertations

The progression of various diseases is associated with alterations in the microenvironment of cells, consisting of a variety of metabolites like lipids and proteins. It is well known that lipids and proteins are potential biomarkers for indicating alterations within the cell microenvironment induced by disease, and various methods are frequently used for their examination. To understand the chemical composition and spatial distribution of constituents in tissues and cells, confocal Raman spectroscopy and microscopy, as non-destructive tools, have shown potential for monitoring abnormalities at the cellular level with high resolution and can facilitate detection through targeting multiple biomarkers. The application of …

Climate change could irreversibly modify Southern Ocean ecosystems. Marine ecosystem model (MEM) ensembles can assist policy making by projecting future changes and allowing the evaluation and assessment of alternative management approaches. However, projected changes in total consumer biomass from the Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) global MEM ensemble highlight an uncertain future for the Southern Ocean, indicating the need for a region-specific ensemble. A large source of model uncertainty originates from the Earth system models used to force FishMIP models, particularly future changes to lower trophic level biomass and sea-ice coverage. To build confidence in regional MEMs …

Climate change is affecting ocean temperature, acidity, currents, and primary production, causing shifts in species distributions, marine ecosystems, and ultimately fisheries. Earth system models simulate climate change impacts on physical and biogeochemical properties of future oceans under varying emissions scenarios. Coupling these simulations with an ensemble of global marine ecosystem models has indicated broad decreases of fish biomass with warming. However, regional details of these impacts remain much more uncertain. Here, we employ CMIP5 and CMIP6 climate change impact projections using two Earth system models coupled with four regional and nine global marine ecosystem models in 10 ocean regions to …

Evaluation Of Soybean Response To Sulfur Fertilizer Rates And Sources, Md Enamul Haque Moni

LSU Master's Theses

Sulfur (S) deficiency has become a significant concern for producers due to over 90% reduction in atmospheric-S deposition since the “Clean Air Act” was established. Soil organic matter, another key source of S, is steadily declining due to continuous tillage. So, we evaluated soybean [Glycine max (L.) Merr.] yield and leaf-S concentration responses to six fertilizer-S rates (0, 11, 22, 34, 45, and 67 kg S ha⁻¹) across 50 site-years, and six fertilizer-S sources (no-S check, Ammonium Sulfate (AMS), Sul4r-Plus/Gypsum, K-Mag, Tiger90CR, and Poly4) across 9 site-years in Louisiana from 2023-2024. In S rate study, soybean yield responded positively to …

Our study presents a data-driven analysis across 312 bacterial species and 154 unique metabolites to enhance the understanding of underlying metabolic processes in gut bacteria. The focus of the study was to create a strategy to generate a theoretical (negative) set for binary classification models to predict the consumption and production of metabolites in the human gut microbiome. Results: Our models achieved median balanced accuracies of 0.74 for consumption predictions and 0.95 for production predictions, highlighting the effectiveness of this approach in generating reliable negative …

Butterfly Species Vary In Sex-Specific Sodium Accumulation From Larval Diets, Luis Y. Santiago-Rosario, Alexander M. Shephard, Emilie Snell-Rood, Achim D. Herrmann, Kyle E. Harms

Faculty Publications

Sodium is essential for animals, and its heterogeneous distribution can cause a range of phenomena, from sodium-seeking behaviours to impacting their performance. Although sodium content in soils and plants is relatively well documented, data for higher trophic levels are limited. Knowledge of the variation in sodium in lower trophic levels could have implications for understanding the behaviour and physiology of species at higher levels. We investigated the variation in tissue sodium concentration between males and females of four butterfly species. Puddling behaviour of Lepidoptera suggests sodium needs of males are generally greater than females, thus, we predicted males would accumulate …

Increased Expression Of The Small Lysosomal Gene Svip In The Drosophila Gut Suppresses Pathophysiological Features Associated With A High-Fat Diet, Brennan M. Mercola, Tatiana V. Villalobos, Jocelyn E. Wood, Ankita Basu, Alyssa E. Johnson

Faculty Publications

Lysosomes are digestive organelles that are crucial for nutrient sensing and metabolism. Lysosome impairment is linked to a broad spectrum of metabolic disorders, underscoring their importance to human health. Thus, lysosomes are an attractive target for metabolic disease therapies. In previous work, we discovered a novel class of tubular lysosomes that are morphologically and functionally distinct from traditionally described vesicular lysosomes. Tubular lysosomes are present in multiple tissues, are broadly conserved from invertebrates to mammals, are more proficient at degrading autophagic cargo than vesicular lysosomes, and delay signs of tissue aging when induced ectopically. Thus, triggering tubular lysosome formation presents …

The Eastern Oyster Behavioral Response To Low Salinity And Hypoxia In Controlled And Natural Settings, Siyah Yongue

LSU Master's Theses

Oyster aquaculture is expanding in the northern Gulf of Mexico, but climate change may challenge the sustainability of this industry. Projected increases in the frequency and intensity of low salinity and low dissolved oxygen (DO) periods could impact the behavior, metabolism, growth, and survival of oysters. Characterizing how oyster behavior links to environmental stressors could help better identify thresholds in their tolerance and inform predictive tools for aquaculture professionals. In this research, the effect of separate and concomitant exposures to low salinity and DO on the behavioral response of oysters was examined in the lab. The impact of other environmental …

Ghost Fishing Due To Derelict Crab Traps In Louisiana’S Barataria Basin, Emma C. Villemarette

LSU Master's Theses

Ghost fishing, the unintentional entrapment of sea life by derelict fishing gear, is an ecologic and socioeconomic concern in Louisiana's crabbing industry (blue crab, Callinectes sapidus). These ghost fishing traps cause unknown and unaccounted for mortality in blue crab and bycatch species. I aimed to track changes to derelict crab trap catch and trap deterioration over seasons and between habitats. I set and monitored 33 simulated derelict crab traps over 367 soak days in three varying habitats along Barataria Bay, Louisiana. Traps were checked once every two weeks and an additional daily check for five days per season. Blue …

The Impact Of Seasonal Hydrological Disturbances On The Presence And Formation Of Toxic Cyanobacteria Blooms In Coastal Louisiana, Courtney Nicole Hammond, Sibel Bargu, Caitlin R.R. Turner, Matthew Hiatt, John R. White

Faculty Publications

Estuaries in the Gulf, especially Lake Pontchartrain Estuary in southeastern Louisiana, USA, are experiencing significant changes due to climate change and coastal restoration efforts. Lake Pontchartrain Estuary receives nutrient-rich Mississippi River water through a controlled diversion called Bonnet Carré Spillway (BCS), which has been associated with toxic cyanobacterial blooms (cyanoHABs). This study examines the seasonal factors influencing cyanoHABs in the Lake Pontchartrain Estuary when the BCS is closed, addressing gaps in the understanding of HABs related to other physical drivers. Field samples collected in 2021, during the closure of the spillway, revealed significant evidence of seasonal variations in cyanoHAB formation. …

Photogrammetric Determination Of Movement Speed Of Invasive Indo-Pacific Lionfish In The Florida Keys, Neal Kolonay, Cassandra N. Glaspie

Faculty Publications

As a key determinant of how efficiently lionfish (Pterois sp.) locate and capture prey, swimming speed plays a crucial role in shaping the predator-prey interactions and broader ecological dynamics within the invaded ecosystems. Swimming speed on a small temporal and spatial scale is difficult to measure because of the need for precise measurements of both distance and duration of the behavior. Using photogrammetry by way of stereo-camera setups is ideal for analyzing the minutiae of lionfish behaviors because it can include the benefits of remote video traps coupled with precise measurements of movements in three-dimensional space and time. The primary …

Comparison Of Two Benthic Assemblage Sampling Gears For Use On Intertidal Oyster Reefs In Louisiana, Finella M. Campanino, Stephanie K. Archer, Jillian C. Tupitza, Cassandra N. Glaspie, Megan K. La Peyre

Faculty Publications

Background: Estuarine biodiversity plays a vital role in supporting ecosystem functions yet remains threatened by climate change and anthropogenic activity. Tracking and identifying estuarine biodiversity trends helps management ensure long-term provisions of human and environmental benefits by contributing to the estimation of habitat loss and the monitoring of restoration and conservation progress. However, results obtained using different sampling gears and different biodiversity metrics may lead researchers to reach different conclusions, which can lead to uncertainty in the actual state of the ecosystem-level biodiversity. Sampling benthic biodiversity in complex estuarine habitats, such as oyster reefs, is particularly challenging because no one …

Kalimantan comprises nearly three quarters of the island of Borneo and is the place where scientific study of Bornean birds began. We describe the history of bird research in Kalimantan from its beginning, highlighting the ornithologists who explored the region and how their interests and methods changed over time, from a concentration on specimen collection, to examinations of community ecology, to conservation in the face of habitat change and species depletion, to the latest investigations using satellite, genetic, and digital technology. We also highlight some future directions for research, especially the need for more work on basic ecology and biogeography. …

Complex Models Of Sequence Evolution Improve Fit, But Not Gene Tree Discordance, For Tetrapod Mitogenomes, Benjamin S. Toups, Robert C. Thomson, Jeremy M. Brown

Faculty Publications

Variation in gene tree estimates is widely observed in empirical phylogenomic data and is often assumed to be the result of biological processes. However, a recent study using tetrapod mitochondrial genomes to control for biological sources of variation due to their haploid, uniparentally inherited, and non-recombining nature found that levels of discordance among mitochondrial gene trees were comparable to those found in studies that assume only biological sources of variation. Additionally, they found that several of the models of sequence evolution chosen to infer gene trees were doing an inadequate job of fitting the sequence data. These results indicated that …

Mathieu-Campbell, Jennifer Irving, Oluwafeyikemi Ogunmusi, Jennifer Richmond-Bryant, Slawomir Lomnicki, Lavrent Khachatryan, Stephania A. Cormier, Tammy R. Dugas

Faculty Publications

Environmentally persistent free radicals (EPFRs) are stable free radicals formed on particulate matter (PM) through processes such as combustion and pyrolysis. These free radicals are generated on transition metal oxide surfaces in the presence of aromatic precursors. Exposure to EPFRs occurs primarily via inhalation of PM deriving from combustion, traffic, industrial activities, and both indoor and outdoor burning. Other environmental factors that might generate EPFRs are radon, electronic and tobacco cigarettes. EPFRs exhibit unexpectedly long half-lives, ranging from several weeks to, in some cases, several years. EPFRs may be carbon-centered, oxygen-centered or mixed, identified by g-values exhibited in electron paramagnetic …

What ‘Unexplored’ Means: Mapping Regions With Digitized Natural History Records To Look For ‘Biodiversity Blindspots’, Laymon Ball, Sheila Rodríguez-Machado, Diego Paredes-Burneo, Samantha Rutledge, David A. Boyd, David Vander Pluym, Spenser Babb-Biernacki, Austin S. Chipps, Rafet Öztürk, Yahya Terzi, Prosanta Chakrabarty

Faculty Publications

We examined global records of accessible natural history voucher collections (with publicly available data and reliable locality data) for terrestrial and freshwater vascular plants, fungi, freshwater fishes, birds, mammals, and herpetofauna (amphibians and reptiles) and highlight areas of the world that would be considered undersampled and sometimes called ‘unexplored’ (i.e., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. We also question what ‘unexplored’ may mean in these contexts and explain how replacing the term in favor of more nuanced phrasing (e.g., ‘biodiversity blindspots,’ which emphasizes the lack of publicly available data about specimens) can …
