In Knowledge We Trust(Ed): A Case Study In Abolition Theatre, Misty Dawn Saribal

LSU Doctoral Dissertations

This dissertation argues for performance art’s role(s) in growing abolition on higher education campuses. After defining abolition’s intersections with higher education, and discussing why performance is often diminished and overlooked, I examine a university abolitionist performance I co-directed that highlighted prison labor on our university’s campus titled ‘In Knowledge We Trusted: Red Tape, White Institutions, and Blue Students.’ A rationale for abolition performance and an abolition performance praxis is detailed with attention to avoiding the pitfalls of authenticity policing in prison abolition and genre policing in abolitionist art. Conclusions about how the performance contributed to and embodied abolition politics and …

Numerical Flume For Wave Dissipation By Mangrove Prop Roots, Rebecca L. Schurr

LSU Master's Theses

Mangroves provide shorelines with many beneficial engineering services, including shoreline stabilization, wave attenuation, and damage mitigation during tsunami or tropical cyclone events. This research focuses on wave attenuation rates and drag coefficients, and how they are affected by mangrove prop roots. Previous lab research using a physical wave flume has quantified wave height decay and drag coefficients for synthetic mangrove forests and confirmed that attenuation does indeed increase as mangrove forest density increases. This research will use a 3D numerical flume model developed in Proteus, a Python package, to simulate prior physical model experiments. This work will attempt to validate …

Times Of Crisis: A Comparative Discourse Analysis Of U.S. And Mexican Presidential Rhetoric, Kassandra Gonzalez-Ramos

LSU Master's Theses

Language is a communicative tool that in the possession of politicians holds the power to be persuasive and aggressive, empowering and uniting, or disruptive and dividing. Previous research has relied on numerous methodological approaches to analyze political discourse from different viewpoints to reveal the manner in which politicians as part of political institutions transform and manipulate language. The current investigation performs a critical discourse analysis (CDA) based on the framework developed by Van Dijk (1993,1997) in order to demonstrate the speech act realization in a total of 14 political speeches delivered by American presidents Biden, Trump, and Obama and Mexican …

The Non-Apprehension Of Selfhood And Metaphysical Freedom, Christopher Rinderle

LSU Master's Theses

In this work I take on one of the most axiomatic assumptions humans possess. The sense of self is embedded so deeply inside each one of us that to question it seems utterly ridiculous. Fortunately, I do not outright reject the notion of selfhood. I investigate what it is and is not through multiple angles – ancient and contemporary – which leads to investigations of free will and responsibility.

In the first chapter, I discuss the Buddhist anātman or non-self. I argue that the historical Buddha did not endorse the idea that the self must be overcome through enlightenment – …

Evaluating The Pesticide-Induced Outbreak Of Soybean Looper, Chrysodeixis Includens (Walker) (Lepidoptera: Noctuidae), In Louisiana Soybean, Scott Lee

LSU Doctoral Dissertations

Soybean looper, Chrysodeixis includens (Walker), has established itself as the primary lepidopteran defoliator in Midsouth soybean agroecosystems. Pesticide-induced outbreak events associated with this pest have been observed by soybean producers. The insecticides believed to prompt these incidents are routinely used for the control of other co-occuring pests, such as stink bugs. Outbreak conditions present soybean producers with conflicting management decisions for pests. Laboratory, greenhouse, and field experiments were conducted to provide a better understanding of insecticide usage impact on populations of C. includens and the arthropod community. To discern the potential mechanisms behind C. includens outbreak, a baseline for the …

The Abolitionist Spectator: Resistant Readings Of Punishment, Rehabilitation, And Reform At The Louisiana State Penitentiary, Kathryn Marie Morris

LSU Doctoral Dissertations

For the majority of the twenty-first century, Louisiana has been the global leader in rates of incarceration. Despite its prevalence, many people encounter prisons and punishment only through representations in movies, television, and the news, remaining distant from the actual processes of punishment and prisons built in remote areas. The Louisiana State Penitentiary at Angola, however, is unique in the number of opportunities it presents for the public to enter the prison for large-scale events like the famous Angola Prison Rodeo, select drama club performances, or to visit the Angola Prison Museum. These opportunities are often read cynically, as moments …

The Global Transcription Factor Fur Is Activated By Binding A [2fe-2s] Cluster To Maintain Iron Homeostasis In Escherichia Coli, Chelsey Rene Fontenot

LSU Doctoral Dissertations

Iron is an essential element for biological functions. Organisms have developed specific mechanisms to acquire, store, and export iron to manage intracellular iron homeostasis. These mechanisms are crucial not only for providing the cells with adequate iron for biological processes but also for ensuring that cells are not overloaded with excess iron, which is highly toxic. The Ferric uptake regulator (Fur) is a global transcription factor for maintaining intracellular iron homeostasis in bacteria. Previously, it was postulated that when the intracellular iron content is elevated, Fur binds ferrous iron to down-regulate the iron acquisition genes and up- regulate the iron …

The Regulation Of Autoimmunity Genes In Pancreatic Β-Cells By Nf-Κb, Thomas Malone Martin

LSU Doctoral Dissertations

Type 1 diabetes (T1D) is an autoimmune disease where the immune system targets the pancreatic islet beta-cells, which are responsible for insulin production and secretion, leading to a state of insulin insufficiency. Many of the molecular details of disease onset and progression remain poorly understood, including key aspects of cytokine signaling. Therefore, we have examined some of the consequences of inflammatory cytokine signaling as a critical module relevant to T1D. Using interleukin-1 (IL-1) signaling as a well-defined paradigm for inflammation, we investigated key components of this signaling pathway in pancreatic beta-cells. We identified ICAM-1, one of the proteins expressed in …

Effects Of Task-Switching On Proactive Control And Metamemory Regulation, Jessica Hacker

LSU Doctoral Dissertations

Past researchers have proposed a relationship between cognitive control and metamemory and several studies have provided the most support for a relationship between task-switching and metamemory regulation. Nevertheless, the evidence has been correlational. To my knowledge, the present study was the first to include an experimental manipulation incorporating a dual-task that required task-switching within a feeling of knowing (FOK) paradigm to directly observe the effects of task-switching on FOK accuracy. Research on cognitive control has demonstrated that engaging in proactive cognitive control typically leads to better performance in cognitive tasks and that young adults are naturally biased to engage in …

Dose Calculation And Prediction Methods For Gamma Knife Stereotactic Radiosurgery, Payton Hayes Stone

LSU Doctoral Dissertations

Implementation of automation routines leveraging deep learning (DL) methods has been a growing topic of interest. The focus of this work is on the Gamma Knife (GK) workflow, specifically the approximation of dose distributions from GK plan parameters and the prediction of dose distributions using DL. These works contribute towards the larger goal of treatment plan prediction and are seen as intermediate steps towards that end. The approximation of dose distributions was motivated by the closed nature of the GK system, which causes complications with the evaluation of the predictions made by the DL models. The approximation utilizes a superposition …

Examining Framing Of Local And National Media Coverage Of Sandy Hook And Robb Elementary School Shootings, Gabrielle L. Debruler

LSU Master's Theses

There have been over 350 K-12 school shootings since the shootings at Columbine High School in 1999 (Cox et al., 2023). Thousands of journalists cover these attacks each in their own way with unique motives. This information goes to the public, and it is up to that person how they want to consume the story and view the shooting. National and local journalists tend to cover school shootings quite differently throughout time with unique frames. The shootings at Sandy Hook Elementary and Robb Elementary Schools illustrate this framing distinctively.

Through a qualitative study of national and local coverage of the …

Quantifying Mud Settling Velocity As A Function Of Turbulence And Salinity In A Deltaic Estuary, Michael W. Mcdonell

LSU Master's Theses

Mud settling velocity is controlled by flocculation, which in turn strongly depends on turbulence and on the chemistry and biology of the water-sediment mixture. As a result, mud settling velocity can be poorly constrained in coastal areas and vary in space and time by orders of magnitude. Here we quantified mud settling velocity in Barataria Basin, a deltaic estuary in Louisiana (USA), using three independent methods: eddy covariance (one station for 200 days), floc cameras (4 stations at one time), and Rouse profile inversion (14 stations, replicated 10-30 times each). Eddy covariance indicates that settling velocity increases with turbulence, at …

Exploring The Interactive, Linguistic, And Conceptual Dimensions Of Parent Input And Their Role In Children's Pragmatic Development, Nickolas T. Day

LSU Master's Theses

The development of children’s pragmatic language, which can be defined as conversational competence in social contexts, has been attributed to variation in the language they hear in their environment. When studying the impact language input has on pragmatic development, it is important for clinicians and linguists to measure both the quantity and quality of this language input. Measures of quality, however, are much more relevant when studying the development of pragmatic language, as discussed in Zhang (2020) and Hirsh-Pasek et al. (2015). Rowe and Snow (2016) discussed three dimensions of language quality: interactive, linguistic and conceptual. There is a current …

A New Test Of The News: An Examination Of The New York Times And Cnn Coverage Of The War In Ukraine, Hannah Ross

LSU Master's Theses

Russia launched a military invasion of Ukraine on 24 February 2022, setting off Europe’s largest war since World War II. The war captured the attention of American news organizations, which gave the conflict unprecedented levels of coverage. This thesis tested the coverage of the war in Ukraine by two major American news outlets: The New York Times and CNN. This study used qualitative content analysis to examine the top four front-page stories of the Times and CNN Newsroom show. Two timeframes were used to analyze these materials: February 24, 2022, to March 9, 2022, and September 17, 2022, to September …

Identifying Key Language Research Priorities In Autistic Children According To Parents, Taylor Hale

LSU Master's Theses

The lack of involvement of the autistic community and its stakeholders in autism research has led to a call to action. At present, autism researchers have limited knowledge about stakeholders’ priorities for research. The current study aimed to bridge the disconnect between the extant autism research and the recent neurodiversity movement by surveying key stakeholders – parents of autistic children – on their perspectives on autism research that focuses on language. Twenty-six parents of autistic children completed an online survey on their views on autism language research with an option to participate in a follow-up interview. Six parents participated in …

Matroid Generalizations Of Some Graph Results, Cameron Crenshaw

LSU Doctoral Dissertations

The edges of a graph have natural cyclic orderings. We investigate the matroids for which a similar cyclic ordering of the circuits is possible. A full characterization of the non-binary matroids with this property is given. Evidence of the difficulty of this problem for binary matroids is presented, along with a partial result for binary orderable matroids.

For a graph G, the ratio of |E(G)| to the minimum degree of G has a natural lower bound. For a matroid M that is representable over a finite field, we generalize this to a lower bound on …

A Study Of Max Reger's Four Sonatas For Solo Violin, Op. 42, No. 1: Analyzing Musical Structure And Exploring Performance Approaches, Hayoung Cho

LSU Doctoral Dissertations

This dissertation examines four sonatas for solo violin op.42, no.1 by Max Reger, a composer relatively unknown in the modern era despite his significant contributions to the violin repertoire. Reger's lack of popularity as a composer for the violin and the infrequency of his solo violin sonatas' performance and recording are the main reasons for this study. The research is based on a comprehensive analysis of Reger's musical language and violin works focusing on his use of polyphonic textures, rhythmic and melodic phrasing, and ornamentation. By examining Reger's compositional techniques, this study aims to shed light on his unique approach …

News(?)Papers: A Typology Of Fake News, 1880-1920, Olivia G. Romaguera

LSU Master's Theses

“Fake news” is a malleable concept. It can be beaten and reshaped to fit many different contexts. One widely accepted definition of fake news is false information purporting itself to be factual. Another is information that is factual but called “fake” in order to discredit it. Concern over the spread of fake news increased in recent years. But preoccupation with what is happening today has left a gap in our understanding of the phenomenon, specifically its roots in the past. “Fake news” was present when news technology was relatively primitive; it is not essentially a function of such modern advancements …

Contribution Of The Microbiome On Reproductive Outcomes During Pregnancy, Kalie Beckers

LSU Doctoral Dissertations

A series of translational comparative studies were performed to investigate the effects of the maternal microbiome on reproductive function and outcomes. With the launch of the human microbiome project in 2007, the next generation sequencing of microbiomes is booming. It is not only in the human medicine field, but also in veterinary species. This study specifically investigates the fecal microbiome in blood pressure high sublime 5 (BPH/5) mouse model that spontaneously develops preeclampsia (PE) and obesity. Additionally, the equine reproductive tract microbiome was explored and compared to microbiome of other host body sites. The BPH/5 mouse is a translational model …

Did The Rapid Transition To Online Learning In Response To Covid-19 Protocols Result In Forced Disclosure By Faculty Members With Invisible Disabilities, Charles Edward Ethridge

LSU Doctoral Dissertations

In December of 2019, the SARS-CoV-2 virus, now commonly referred to as COVID-19, was first identified in Wuhan, China. The virus proved highly contagious and quickly spread around the globe. By April 7, 2020, Stay-at-Home orders and/or directives regarding the closures of non-essential businesses and schools had been issued throughout the US. While there has been considerable research since 2020 regarding the impact of COVID-19 on higher education, nearly all the research has focused on the effects on students, the economic impact on institutions, and the future landscape of higher education. However, there is little research regarding the effect on …

Health Service Utilization And Conduct Problems: The Role Of Callous-Unemotional Traits And Juvenile Justice System Processing, Julianne Speck

LSU Master's Theses

Previous research indicates that youth with conduct problems, who are overrepresented in the juvenile justice system, are at risk for utilizing a disproportionate amount of health services compared to youth without these problems. The present study investigates self-reported antisocial behavior, juvenile justice system processing type, and callous-unemotional (CU) traits as predictors of health service utilization (medical and mental health service use and out-of-home placement) across adolescence in a sample of justice-involved males from the Crossroads Study. A total of 766 participants provided data at ten appointments over a period of seven years. A series of linear multiple regressions were used …

Is There A Balance Between The U.S. Government Secrecy Regime And Free Speech Rights Of Government Employees?: The Legal Landscape Of The U.S. Government Control Of Information, Qinqin Wang

LSU Doctoral Dissertations

This dissertation explores the tension between the U.S. government’s control of information and government employees’ claims to free speech rights. The U.S. government prepublication review is a censorship system that requires former and current federal government employees to submit any materials intended for publication to their agencies for prior review before they attempt to make any external communication or proceed with any publications. The prepublication review regime has become an essential means by which the U.S. government controls internal information, and has long been controversial because of its censorship nature. Specifically, this dissertation focuses on legal disputes between the U.S. …
