My Favorite Murder As Discursive Performance, Taylor Dawson

LSU Doctoral Dissertations

My Favorite Murder as Discursive Performance uses performance-centered discourse analysis to explore the major narratives informing the popular true crime comedy podcast, My Favorite Murder (MFM). Hosts, Karen and Georgia draw from podcast, comedy, true crime, feminist, and mental health discourse to create a unique discursive space where “murderinos” (fans of the podcast) express and explore aspects of their own life experiences. I explore the performative strategies MFM uses and the effects of those choices, drawing on some of my own experiences as a murderino. Ultimately I argue that a performance lens reveals some of the imperfect but powerful ways …

Infrared Investigation Of Lithium Ion Electrolytes: Characterization Of Structure And Dynamics Via Linear And Nonlinear Spectroscopy, Jeramie Christopher Rushing

LSU Doctoral Dissertations

Lithium ion batteries are widely employed in energy storage, but the connection between the molecular interactions in their electrolytes and the macroscopic properties remains elusive. Across three vastly different electrolytes, speciation and dynamics were studied via linear and nonlinear infrared spectroscopy to shed light on this relationship. The impact of mixed solvation on ionic speciation was studied from the perspective of the anion, which revealed a significant energetic favorability for the formation of contact ion pairs in linear carbonate solvents over cyclic carbonates. Infrared spectroscopy and density functional theory calculations described a complete inversion of the speciation due to solvent …

Connecting The Dots: Transmission Of Stony Coral Tissue Loss Disease From The Marquesas To The Dry Tortugas, Thomas Dobbelaere, Daniel M. Holstein, Erinn M. Muller, Lewis J. Gramer, Lucas Mceachron, Sara D. Williams, Emmanuel Hanert

Faculty Publications

For the last 7 years, Florida's Coral Reef (FCR) has suffered from widespread and severe coral loss caused by stony coral tissue loss disease (SCTLD). First observed off the coast of Miami-Dade county in 2014, the outbreak has since spread throughout the entirety of FCR and some areas of the Caribbean. However, the propagation of the disease through FCR seemed to slow down when it reached the western end of the Marquesas in August 2020. Despite being present about 30 km (similar to 20 miles) from the Dry Tortugas (DRTO), SCTLD was not reported in this area before May 2021. …

One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges and taxonomic difficulties connected to the species concept definition, the global numbers of species, including those of important and well-studied life forms such as trees, still remain largely unknown. Here, based on global ground-sourced data, we estimate the total tree species richness at global, continental, and biome levels. Our results indicate that there are ∼73,000 tree species globally, among which ∼9,000 tree species are yet to be discovered. Roughly 40% of undiscovered tree species are in South …

Inhibition Of Biotin Carboxylase By Three Antibacterial Compounds, Matt Craft

LSU Doctoral Dissertations

The rise of antibacterial resistant bacteria is a major problem in the United States of America and around the world. Millions of patients are infected with antimicrobial resistant bacteria each year. Novel antibacterial agents are needed to combat the growing and present crisis. Acetyl-CoA carboxylase (ACC), the multi-subunit complex which catalyses the first committed step in fatty acid synthesis, is a validated target for antibacterial agents. However, there are at present, no commercially available antibiotics that target ACC. Ethyl 4-[[2-chloro-5-(phenylcarbamoyl)phenyl]sulfonylamino]benzoate (SABA1) is a compound that has been shown to have antibacterial properties against Pseudomonas aeruginosa and Escherichia coli. SABA1 inhibits …

Faculty Publications

Aims. The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpose of identifying the origin of the anomaly.

Methods. We model the light curve under various interpretations. From this, we find four solutions, in which three solutions are found under the assumption that the lens is composed of two masses (2L1S models), and the other solution is found under the assumption that the source is comprised of binary stars (1L2S model). The 1L2S model is ruled out based on the contradiction that the …

Tale Of A Non-Interacting Additive In A Lithium-Ion Electrolyte: Effect On Ionic Speciation And Electrochemical Properties, J C. Rushing, C M. Stern, N Elgrishi, D G. Kuroda, J C. Rushing

Faculty Publications

New lithium electrolytes compatible with high energy density cells are critical for lithium metal battery applications, but dendrite formation associated with the use of dilute organic electrolytes complicates their realization. High-concentration electrolytes mitigate some of the issues of the electrolytes but introduce additional problems, such as low conductivity and high cost. Hence, pseudo-concentrated electrolytes, wherein a co-solvent is added to a dilute electrolyte, have been presented as a possible alternative to both dilute and concentrated electrolytes. However, the effect that the co-solvent has on the electrolyte properties at both macroscopic and microscopic levels is unknown. Here, a study of the …

A Bayesian Phase I/Ii Biomarker-Based Design For Identifying Subgroup-Specific Optimal Dose For Immunotherapy, Beibei Guo, Yong Zang

Faculty Publications

Immunotherapy is an innovative treatment that enlists the patient's immune system to battle tumors. The optimal dose for treating patients with an immunotherapeutic agent may differ according to their biomarker status. In this article, we propose a biomarker-based phase I/II dose-finding design for identifying subgroup-specific optimal dose for immunotherapy (BSOI) that jointly models the immune response, toxicity, and efficacy outcomes. We propose parsimonious yet flexible models to borrow information across different types of outcomes and subgroups. We quantify the desirability of the dose using a utility function and adopt a two-stage dose-finding algorithm to find the optimal dose for each …

Intact, Commercial Lithium-Polymer Batteries: Spatially Resolved Grating-Based Interferometry Imaging, Bragg Edge Imaging, And Neutron Diffraction, A J. Brooks, D S. Hussey, K Ham, D L. Jacobson, A J. Brooks, N Kardjilov, L G. Butler

Faculty Publications

We survey several neutron imaging and diffraction methods for non-destructive testing and evaluation of intact, commercial lithium-ion batteries. Specifically, far-field interferometry was explored as an option to probe a wide range of autocorrelation lengths within the batteries via neutron imaging. The dark-field interferometry images change remarkably from fresh to worn batteries, and from charged to discharged batteries. When attempting to search for visual evidence of battery degradation, neutron Talbot-Lau grating interferometry exposed battery layering and particle scattering through dark-field imaging. Bragg edge imaging also reveals battery wear and state of charge. Neutron diffraction observed chemical changes between fresh and worn, …

Predator-Pest Dynamics Of Arthropods Residing In Louisiana Soybean Agroecosystems, Scott T. Lee, Chaoyang Li, Jeffrey A. Davis

Faculty Publications

Over the past two decades, management practices within Louisiana soybean production have shifted. Successful application of an integrated pest management (IPM) strategy requires an understanding of how these changes have affected predator-pest dynamics. Surveys monitoring foliage-foraging arthropod populations in soybean took place across six locations within Louisiana over six years (2012–2014 and 2015–2018). Temporal associations of pest groups, defoliating and piercing-sucking, and predator groups relating to soybean phenology were observed. Additionally, soybean maturity groups (III, IV, and V) were also evaluated to delineate potential differences. Results indicated higher abundances of piercing-sucking pests compared to defoliating pests across both datasets (2012–2014 …

Optimal Eco-Compensation For Forest-Based Carbon Sequestration Programs: A Case Study Of Larch Carbon Sink Plantations In Gansu, Northwest China, Wei Yew Chang, Zhuolun Li, Kefei Lu, Sun J. Chang

Faculty Publications

This study investigated the potential financial benefits that private forest famers can derive when participating in a larch carbon sink plantation project in the northwestern Chinese province of Gansu. A decision matrix was developed to help forest farmers justify participation in forest carbon sink projects relative to the traditional land-use goal of timber production under various carbon trading prices, site conditions, and contract terms. The results showed that when the carbon trading price is at the theoretically optimal carbon price (CNY 110/tCO2e, equivalent to USD 17/tCO2e), Chinese business entities are willing to pay for forest carbon credits under the current …

Exercise Reduces The Protein Abundance Of Txnip And Its Interacting Partner Redd1 In Skeletal Muscle: Potential Role For A Pka-Mediated Mechanism, Alec B. Chaves, Edwin R. Miranda, Jacob T. Mey, Brian K. Blackburn, Kelly N.Z. Fuller, Blaise Stearns, Andrew Ludlow, David L. Williamson, Joseph A. Houmard, Jacob M. Haus

Division of Basic Science Faculty Publications

Thioredoxin-interacting protein (TXNIP) negatively effects the redox state and growth signaling via its interactions with thioredoxin (TRX) and regulated in development and DNA damage response 1 (REDD1), respectively. TXNIP expression is downregulated by pathways activated during aerobic exercise (AE), via posttranslational modifications (PTMs; serine phosphorylation and ubiquitination). The purpose of this investigation was to determine the effects of acute AE on TXNIP expression, posttranslational modifications, and its interacting partners, REDD1 and TRX. Fifteen healthy adults performed 30 min of aerobic exercise (80% V_ O2max) with muscle biopsies taken before, immediately following, and 3 h following the exercise bout. To explore …

Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation-prone asthma, who contribute disproportionately to disease burden. Extensive deep phenotyping has revealed the heterogeneous nature of severe asthma and identified distinct disease subtypes. A current challenge in the field is to translate new and emerging knowledge about different pathobiologic mechanisms in asthma into patient-specific therapies, with the ultimate …

Interpretation And Inference For Altmetric Indicators Arising From Sparse Data Statistics, Lawrence Smolinsky, Bernhard Klingenberg, Brian D. Marx

Faculty Publications

In 2018 Bornmann and Haunschild (2018a) introduced a new indicator called the Mantel-Haenszel quotient (MHq) to measure alternative metrics (or altmetrics) of scientometric data. In this article we review the Mantel-Haenszel statistics, point out two errors in the literature, and introduce a new indicator. First, we correct the interpretation of MHq and mention that it is still a meaningful indicator. Second, we correct the variance formula for MHq, which leads to narrower confidence intervals. A simulation study shows the superior performance of our variance estimator and confidence intervals. Since MHq does not match its original description in the literature, we …

Faculty Publications

The Aurora Subglacial Basin (ASB) catchment contains 3–5 m of sea-level equivalent ice volume that drains to the Sabrina Coast, East Antarctica via the Totten Glacier system. Observed thinning and retreat of Totten Glacier indicate regional sensitivity to oceanographic and atmospheric warming. Paleoclimate studies of climatically sensitive catchments are required to understand the evolution of the East Antarctic Ice Sheet (EAIS) and its outlet glacier systems. Recent seismic and sediment studies from the Sabrina Coast document the evolution of the EAIS in the ASB catchment, suggesting that the region has long been sensitive to climatic changes. This study presents new …

Faculty Publications

Catheters integrated with microcoils for electromagnetic steering under the high, uniform magnetic field within magnetic resonance (MR) scanners (3-7 Tesla) have enabled an alternative approach for active catheter operations. Achieving larger ranges of tip motion for Lorentz force-based steering have previously been dependent on using high power coupled with active cooling, bulkier catheter designs, or introducing additional microcoil sets along the catheter. This work proposes an alternative approach using a heat-mitigated design and actuation strategy for a magnetic resonance imaging (MRI)-driven microcatheter. A quad-configuration microcoil (QCM) design is introduced, allowing miniaturization of existing MRI-driven, Lorentz force-based catheters down to 1-mm …

The Effects Of Team Surface-Level Diversity On Creativity & Innovation, Roman Mitchell

Faculty Publications

During the last 20 years, the global marketplace has become more competitive due to increased globalization, aggressive market competition, and changing customer demands. This has forced organizations to assemble teams with diverse knowledge, skills, and abilities to remain competitive. However, previous meta-analytic investigations examining the relationship between team surface-level diversity (i.e., race or gender identity), creativity, and innovation have indicated a small negative relationship. Despite the said positive effects of team diversity, theory and empirical evidence suggests that increased surface-level team diversity leads to decreased team collaboration, team cohesion, and diminished creativity and innovation (Bell, 2007).

An Investigation Of How Previous Diagnoses Affect The Developmental Functioning Of Children At Risk For Autism Spectrum Disorder, Michaela Brown

LSU Master's Theses

Research has shown that children with autism spectrum disorder (ASD) often have co-occurring medical and/or psychiatric disorders. This current study aimed to investigate how previous diagnoses, which may become comorbidities of ASD if diagnosed, affect the developmental functioning of children presenting as at risk for ASD compared to those presenting with no risk. Developmental areas such as communication, motor, adaptive, cognitive and social, as well as overall developmental functioning, were considered in the analysis. 11,970 children under the age of three were studied. Results found that the presence of previous diagnoses significantly predicted developmental functioning, particularly in the motor functioning …

Three Essays On Climate Smart Agriculture And Multidimensional Poverty In Uganda, Sarah Kagoya

LSU Doctoral Dissertations

Agriculture is the backbone of the Ugandan economy. It contributes about 23.1% to the gross domestic product and employs approximately 72% of the total labor force (World Bank, 2021). However, Uganda suffers from low agricultural productivity resulting from pests and diseases, changing climate, deteriorating natural resources, and lack of modern factors of production. In addition, land deterioration and fluctuating weather patterns lead to reduced crop productivity and cause food insecurity in the country. Climate-Smart Agriculture (CSA) can help transform the agricultural system and ensure food security in the country.

The dissertation is written in a three-essay format. The first essay …
