The Effects Of Disclosure Of Genai Use In The Production Of Advertising In High And Low Involvement Settings, Shawn Griffin

LSU Master's Theses

This study explores the effects of GenAI disclosure on advertising effectiveness and how these influences interact with consumers’ involvement in advertised products using a 2×2 experimental design with 83 participants, manipulating AI disclosure (disclosed vs. not disclosed) and involvement level (high vs. low). Findings indicate that disclosure negatively impacts brand attitude but has no significant effect on ad attitude, purchase intention, or sharing intention. An interaction effect was also found that in high-involvement conditions, disclosure increased the intention to share the ad. These results, framed through the Elaboration Likelihood Model (ELM) and Persuasion Knowledge Model (PKM), offer insights into the …

On Unavoidable Infinite Hypergraphs, Samuel Weiner

LSU Doctoral Dissertations

Ramsey's Theorem states that every infinite graph contains either K_∞ or $\overline{K_∞}$ as an induced subgraph. For this reason, K_∞ and $\overline{K_∞}$ are often referred to as the unavoidable infinite graphs. Many similar results have characterized the unavoidable members for various classes of infinite graphs; perhaps the most notable of these is König's Infinity Lemma, which states that every infinite, connected, locally finite graph contains a ray as an induced subgraph. From these findings, one can easily deduce that every infinite, connected graph contains an infinite clique, star, or ray as an induced subgraph; …

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 …

Silent Period Versus Selective Mutism In Young Bilingual Children: A Case Study, Blake Alley

LSU Master's Theses

Intro: It is difficult to distinguish between typical bilingual communication behaviors and those of monolinguals with communication disorders. One difficulty is distinguishing between a silent period and selective mutism. A silent period refers to a relatively brief period of time during which a bilingual refuses to speak in unfamiliar language contexts. Selective mutism refers to a refusal to speak for a long period of time in any language context. The purpose of this study is to disentangle selective mutism from a silent period for a 4 year 10-month-old Spanish English bilingual female.

Methods: This study will include questionnaires, and seven …

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 …

Bayesian Network-Based Framework To Uncover Social Inequities In Flood Risk: Application To East Baton Rouge Parish, Louisiana, Fuad Hasan

LSU Master's Theses

Regional flood risk assessment requires understanding the complex interplay of sociodemographic, socioeconomic, hydrogeologic, built environment, and climatic variables that impact flood vulnerability. Traditional studies often focus on large-scale units, overlooking localized variations and disproportionate exposure within populations. To address these gaps, a methodological framework of flood risk assessment using the Bayesian network was proposed and applied to East Baton Rouge Parish, Louisiana, for the August 2016 flood event to identify relationships between flood risk variables at the housing unit level. Flood exposure representativeness (FER) was determined using the Bayesian network's inference capabilities to identify over- or under-represented groups. This study …

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 …

An Interdisciplinary Analysis Framework For Found Object Experimental Music, Erin Demastes

LSU Doctoral Dissertations

Found object experimental music consists of compositions and performances created with objects not intended for musical performance. Found objects can range from appliances and household items to power tools and consumer products to souvenirs and heirlooms. Although these objects are used with the intent of creating musical compositions, new characteristics that are not found in traditional music emerge. One major characteristic that differentiates found object music from traditional music is that the objects have inherent cultural associations and meaning outside of their use in the composition. While an analysis of the sonic structures and scores of found object experimental music …

Infrared Laser Ablation Of Biomolecules From Formalin-Fixed Tissue, Blessing Chisom Egbejiogu

LSU Doctoral Dissertations

In the research described in this dissertation, a high-precision infrared laser ablation microsampling method was utilized for spatially resolved proteomic and lipidomic analyses of formalin fixed paraffin embedded (FFPE) tissue, a widely used archival sample in biomedical research. Despite its extensive use, FFPE tissue presents challenges for proteomic analysis due to protein cross-linking and modifications introduced during fixation, which can hinder extraction and identification. Developing a streamlined high-resolution method to recover biomolecules from FFPE samples is critical for advancing biomarker discovery, retrospective studies, and multi-omics research. To address these challenges, this study employs an infrared (IR) laser ablation microdissection system …

Trans-Arg: Predicting Antibiotic Resistance Genes With A Transformer-Based Model And Pretrained Protein Language Model, Mohd Manzar Abbas, Amit Ranjan, Aixin Hou, Supratik Mukhopadhyay

Faculty Publications

Antibiotic resistance presents an emerging challenge to global health by reducing the efficacy of antibiotics administered to treat bacterial infections. Traditional approaches for detecting antibiotic resistance genes (ARGs) involve alignment-based sequence similarity techniques, which are time-consuming and resource-intensive. This signifies the necessity for developing advanced computational methods to detect ARGs early. To address this challenge, we introduce Trans-ARG, a novel multi-head attention transformer-based model designed to predict potential ARGs. Our approach leverages the pretrained ESMFold model to extract embeddings from protein sequences, capturing intricate structural and functional information. Protein sequences labelled as ARG or non-ARG were used as the dataset. …

Sensitivity Of Spatial And Temporal Precipitation Patterns To Aerosol Loadings During An Extreme Precipitation Event, Wenjia Cao, Robert V. Rohli, Paul W. Miller

Faculty Publications

Aerosols are important modulators of the precipitation-generating process, with their concentrations potentially affecting the precipitation process in extreme events. Existing literature suggests that, through microphysical processes, additional aerosols lead to a larger number of smaller cloud droplets, which eventually redistributes the latent heat and the precipitation process. This research addresses the question of how sensitive the spatial and temporal patterns of heavy precipitation events are to aerosol concentration. National Centers for Environmental Prediction (NCEP) Global Data Assimilation System (GDAS) final (FNL) data were used as input to the Weather Research and Forecasting (WRF) model, to simulate the case study of …

Urban Sprawl Drives Heterogeneous Flood Exposure Patterns Along Socio-Demographic Gradients: A Case Study In The Amite River Basin During The 2016 Louisiana (Usa) Floods, Israt J. Tama, Thomas Douthat, Kevin Smiley, Rebeca De Jesús Crespo

Faculty Publications

The impact of floods may be exacerbated due to urban sprawl, which leads to residential development in naturally flood-prone areas. In the United States (US), urban sprawl has been historically tied to racial segregation, while flood-prone suburban development has been facilitated by flood insurance. While previous studies have found links between flood exposure and socio-demographic inequities, no research has addressed this question by looking at watershed-level segregation and the location of properties relative to flood-prone areas. We evaluate socio-demographic patterns of flood impact during the 2016 Floods in Louisiana (LA), USA, and whether these impacts differed inside or outside the …

From The Mountains To The Beach: Water Purification Ecosystem Services And Recreational Beach Use In Puerto Rico, Maya Corridore, Rebeca De Jesús Crespo, Mariam Valladares-Castellanos, Thomas Douthat

Faculty Publications

Recreational beach use is important for coastal economies and is influenced by water clarity, a trait that may be maintained by water purification ecosystem services (ESs). However, few studies have addressed these linkages. In this study, we ask the following questions: (1) Do watershed-scale water purification ecosystem services influence coastal water quality? (2) Does coastal water quality help explain beach visitation rates? To address these questions, we focused on Puerto Rico (PR), where coastal tourism has economic and cultural importance. We estimated water purification ESs using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), coastal water quality using long-term …

Faculty Publications

We have conducted a comprehensive investigation into the magnetic properties of the chiral multiferroic material CoTeMoO6. In contrast with the previous claim of canted antiferromagnetic order with ferromagnetic components [Y. Doi, J. Solid State Chem. 182, 3232 (2009)10.1016/j.jssc.2009.09.008], our investigation reveals an antiferromagnetic ground state with compensated moments, providing an interesting platform for exploring exotic material properties. Through careful measurements of magnetization under a series of applied fields, we demonstrate that there exist two sequential field-induced magnetic transitions in CoTeMoO6, with one occurring at Hc1=460 Oe along the a axis, and the other at Hc2=1.16 T with the field along …

Religious Nationalism: Narendra Modi’S 2019 Election Victory Speech, Nihar Sreepada

Faculty Publications

The ideology of nationalism is permeating and ascending across societies, eventually manifesting materially in several nations across the world. In this essay, I analyze the religious manifestation of nationalism within the context of India’s Hindu nationalism. I argue that Modi, in his 2019 election victory speech, constructs a grand narrative of Hindu nationalistic unification by positioning himself as a Hindu sanyasi (ascetic) and by alluding to Hindu mythologies. First, I present the historical context of India’s Hindu nationalism (Hindutva). Second, I explicate the formation of an ideological discourse through Kenneth Burke’s focus on identification and the constitutive rhetoric of calling …
