From Empowerment Movement To Hijacked Hashtag: A Thematic Analysis Of #Shoutyourabortion, Sidney R. Reynen Nov 2023

From Empowerment Movement To Hijacked Hashtag: A Thematic Analysis Of #Shoutyourabortion, Sidney R. Reynen

LSU Master's Theses

This study delves into the digital landscape of the contentious abortion debate, focusing on the use and hijacking of the Shout Your Abortion hashtag. Drawing parallels to previous research on digital feminism, hashtag activism, and hashtag hijacking, this study further expands such literature by revealing shifts in anti-abortion rhetoric and strategies post-Dobbs. I identified seven themes within the supportive discourse: abortion narratives, pro-choice and other feminist rhetoric, calls to action, feminist art and shareables, reproductive health information and resources, positive-to-neutral mentions of the movement, and engagements with anti-abortion users. Within the hijacked posts, I identified five themes: Shout …

Translation Speed Influence On Tropical Cyclone Storm Tide And Surge Generation Along The Gulf Of Mexico Coast, Samantha L. Camarda Nov 2023

Translation Speed Influence On Tropical Cyclone Storm Tide And Surge Generation Along The Gulf Of Mexico Coast, Samantha L. Camarda

LSU Master's Theses

This research examines tropical cyclone translation speed as a factor in storm tide and surge height upon landfall on the United States Gulf Coast. Understanding the effect of translation speed on peak storm tide/surge height is needed to better prepare for and predict future damage from tropical cyclone events. Tropical cyclone data are taken from hourly interpolated best-track HURDAT2 data from 1970–2021. This study uses the HURDAT2 hourly interpolated observation data points (24-hours) pre-landfall to landfall. Translation speed is calculated based on the distance traversed between hourly points. Peak storm tide and storm surge data are taken from SURGEDAT from …

Containerized Satsuma Mandarin Production Under Protective Screens As A Management Strategy, Anna Timmerman Nov 2023

Containerized Satsuma Mandarin Production Under Protective Screens As A Management Strategy, Anna Timmerman

LSU Master's Theses

Many of the world’s citrus growing regions are experiencing challenges related to citrus greening, also known as Huanglongbing (HLB) caused by the presumed bacterial agent Candidatus Liberibacter spp. HLB is vectored by the Asian citrus psyllid (Diaphorina citri) and through propagation of infected citrus material. HLB impacts tree health as well as fruit development, ripening, and quality of the resulting citrus fruit, often leading to an unmarketable product. Producers are growing citrus in high density orchards underneath protective screening material that excludes the Asian citrus psyllid, preventing new HLB infections. Four ultra-high containerized tree spacings of 2 feet …

A Membrane Protein Of The Rice Pathogen Burkholderia Glumae Required For Oxalic Acid Secretion And Quorum Sensing, Asif Iqbal, George Nwokocha, Vijay Tiwari, Inderjit K. Barphagha, Anne Grove, Jong Hyun Ham, William T. Doerrler

Faculty Publications

Bacterial panicle blight is caused by Burkholderia glumae and results in damage to rice crops worldwide. Virulence of B. glumae requires quorum sensing (QS)-dependent synthesis and export of toxoflavin, responsible for much of the damage to rice. The DedA family is a conserved membrane protein family found in all bacterial species. B. glumae possesses a member of the DedA family, named DbcA, which we previously showed is required for toxoflavin secretion and virulence in a rice model of infection. B. glumae secretes oxalic acid as a “common good” in a QS-dependent manner to combat toxic alkalinization of the growth medium …

Faculty Publications

Denitrifying bioreactors (DNBRs) are a sustainable and cost-effective practice commonly used at the edge of fields to reduce nitrate from agricultural runoff. The hydraulic retention time (HRT) is a crucial variable that affects nitrate removal rate (NRR, g N m−3 d−1), nitrate removal efficiency (NRE, %), and nitrate concentration reduction per length (Nrd, mg N L−1 m−1). In this study, two nonlinear models, the developed Michaelis-Menten (MM) model and the Mitscherlich (MT) model, were developed to characterize the relationship between nitrate removal indices (NRR, NRE, and Nrd) and HRT. This study first utilizes nonlinear models to quantitatively understand the relationship …

Bariatric Surgery Alters Mitochondrial Function In Gut Mucosa, Robert C. Ross, Elizabeth C. Heintz, Elizabeth R.M. Zunica, R. Leigh Townsend, Amanda E. Spence, Philip R. Schauer, John P. Kirwan, Christopher L. Axelrod, Vance L. Albaugh

Division of Basic Science Faculty Publications

Background: The obesity pandemic has worsened global disease burden, including type 2 diabetes, cardiovascular disease, and cancer. Metabolic/bariatric surgery (MBS) is the most effective and durable obesity treatment, but the mechanisms underlying its long-term weight loss efficacy remain unclear. MBS drives substrate oxidation that has been linked to improvements in metabolic function and improved glycemic control that are potentially mediated by mitochondria—a primary site of energy production. As such, augmentation of intestinal mitochondrial function may drive processes underlying the systemic metabolic benefits of MBS. Herein, we applied a highly sensitive technique to evaluate intestinal mitochondrial function ex vivo in a …

Oxidation 1-Methyl Naphthalene Based On The Synergy Of Environmentally Persistent Free Radicals (Epfrs) And Pahs In Particulate Matter (Pm) Surface, Ajit Ghimire, Farhana Hasan, Xia Guan, Phillip Potter, Chuqi Guo, Slawo Lomnicki

Faculty Publications

Studies of the environmental fate through the interactions of particle-associated polycyclic aromatic hydrocarbons (PAHs) with environmentally persistent free radicals (EPFRs) are presented. The formation of PAHs and EPFRs typically occurs side by side during combustion-processes. The laboratory simulation studies of the model PAH molecule 1-Methylnaphthalene (1-MN) interaction with model EPFRs indicate a transformational synergy between these two pollutants due to mutual and matrix interactions. EPFRs, thorough its redox cycle result in the oxidation of PAHs into oxy-/hydroxy-PAHs. EPFRs have been shown before to produce OH radical during its redox cycle in aqueous media and this study has shown that produced …

A Descriptive Study Of Louisiana 4-H 8th Through 12th Graders' Perceptions Of Career And College Readiness, Carrie M. Lane Nov 2023

A Descriptive Study Of Louisiana 4-H 8th Through 12th Graders' Perceptions Of Career And College Readiness, Carrie M. Lane

LSU Master's Theses

As youth leave primary education and enter college or a career path, preparing those youth to ensure success has fallen, in large part, upon formal and non-formal youth educators. Encouraging students to apply and complete college has been a focus of education professionals for many years. Historically, gauging college and career readiness (CCR), academic institutions have relied on academic performance in areas of English Language Arts and Mathematics (Mattern, et. al, 2014). The use of academic focused measures instead of student-based evaluation had its drawbacks. While core education is important, measuring soft skills needed for the workforce and college environment …

Entorhinal Cortical Delta Oscillations Drive Memory Consolidation, Juhee Haam, Suman Gunin, Leslie Wilson, Sydney Fry, Briana Bernstein, Eric Thomson, Hayden Noblet, Jesse Cushman, Jerrel L. Yakel

Faculty Publications

Long-term memories are formed by creating stable memory representations via memory consolidation, which mainly occurs during sleep following the encoding of labile memories in the hippocampus during waking. The entorhinal cortex (EC) has intricate connections with the hippocampus, but its role in memory consolidation is largely unknown. Using cell-type- and input-specific in vivo neural activity recordings, here we show that the temporoammonic pathway neurons in the EC, which directly innervate the output area of the hippocampus, exhibit potent oscillatory activities during anesthesia and sleep. Using in vivo individual and populational neuronal activity recordings, we demonstrate that a subpopulation of the …

Μconadapter: Reinforcement Learning-Based Fast Concurrency Adaptation For Microservices In Cloud, Jianshu Liu, Shungeng Zhang, Qingyang Wang Oct 2023

Μconadapter: Reinforcement Learning-Based Fast Concurrency Adaptation For Microservices In Cloud, Jianshu Liu, Shungeng Zhang, Qingyang Wang

Faculty Publications

Modern web-facing applications such as e-commerce comprise tens or hundreds of distributed and loosely coupled microservices that promise to facilitate high scalability. While hardware resource scaling approaches [28] have been proposed to address response time fluctuations in critical microservices, little attention has been given to the scaling of soft resources (e.g., threads or database connections), which control hardware resource concurrency. This paper demonstrates that optimal soft resource allocation for critical microservices significantly impacts overall system performance, particularly response time. This suggests the need for fast and intelligent runtime reallocation of soft resources as part of microservices scaling management. We introduce …

Yeast Crf1p: An Activator In Need Is An Activator Indeed, Sanjay Kumar Oct 2023

Yeast Crf1p: An Activator In Need Is An Activator Indeed, Sanjay Kumar

LSU Doctoral Dissertations

Ribosome biogenesis is an energetically costly process, and tight regulation is required for stoichiometric balance between components. This requires coordination of RNA polymerases I, II, and III. Lack of nutrients or the presence of stress leads to downregulation of ribosome biogenesis, a process for which mechanistic target of rapamycin complex I (mTORC1) is key. mTORC1 activity is communicated by means of specific transcription factors, and in yeast, which is a primary model system in which transcriptional coordination has been delineated, transcription factors involved in regulation of ribosomal protein genes include Fhl1p and its cofactors, Ifh1p and Crf1p. Ifh1p is an …

Faculty Publications

We report an enantioselective synthesis of cyclic ketones with full substitutions at the α-positions in a highly diastereoselective manner. Our method is achieved by subjecting substrate motifs in 2-allyloxyenones to chiral organomagnesium reagents, which trigger the Claisen rearrangement upon direct 1,2-carbonyl addition. The observed diastereoselectivity of the allyl migration is proposed to originate from the intramolecular chelation of the magnesium alkoxide to the allyloxy moiety.

Problem Recognition In Culturally Diverse Parent Mental Health Help Seeking, Grace Chen Oct 2023

Problem Recognition In Culturally Diverse Parent Mental Health Help Seeking, Grace Chen

LSU Doctoral Dissertations

There is evidence of a disparity between mental health prevalence rates in children and service utilization. Thus, many children are not receiving support for their mental health needs despite prevalent symptoms and high levels of psychopathology. This disparity is even greater for children from culturally diverse families who face unique stressors in comparison to their White peers. Given the known positive and preventative effects of early intervention, this places culturally diverse children at disproportionate risk for adverse mental health outcomes. Parents are gatekeepers responsible for responding to their child’s mental health needs. Thus, it is necessary to study the unique …

Proud Of Your Boy: Toxic Masculinity, Boyhood, And The American Musical, Aaron J. Wood Oct 2023

Proud Of Your Boy: Toxic Masculinity, Boyhood, And The American Musical, Aaron J. Wood

LSU Doctoral Dissertations

This project traces the cultural historiography of the phrase "boys will be boys" and examines the pattern of white male excusal it embodies through a case-study based survey of onstage depictions of boyhood in musical theatre. I argue that the generational idea of manhood as aggressive, competitive, and violent is continually reasserted through our passive acceptance of white boy violence. This dissertation looks to the musicals Newsies, West Side Story, Heathers, and Dear Evan Hansen as case studies for exploring the cultural lineage of the phrase “boys will be boys.” Like the works of Aaron Thomas, Raymond …

Structural And Functional Characterizations Of The Two Mini-Ferritins In Pseudomonas Aeruginosa Revealed The Coexistence Of A Classic Dps (Pa0962) And A Dps-Like (Pa4880) Protein, Rajapaksha Pathirannahalage Nimesha Hansani Rajapaksha

LSU Doctoral Dissertations

In the P. aeruginosa genome, gene PA0962 codes for a probable DNA-binding protein from starved cells (Pa Dps). Pa Dps is assembled from 12 monomers, each consisting of a four-helix bundle fold typical of Dps proteins. A subunit dimer of Pa Dps harbors two ferroxidase centers. Assembly of a dodecameric structure of Pa Dps is favored by the presence of divalent metal ions and at pH 6.0 in the absence or presence of divalent cations. Pa Dps is unable to form the large DNA-protein complexes typical of many Dps proteins. Instead, Pa Dps acts on plasmid DNA to form relaxed …

Building Solidarity Between Minority Groups, Seonwoo Kim

LSU Doctoral Dissertations

Although a considerable number of scholars agree that an intergroup coalition among minorities will be more powerful in changing biased perceptions, regulations, and policies (e.g., Burson & Godfrey, 2020; Lane et al., 2019), cross-minority solidarity is challenging due to the inherent difficulties in establishing a shared goal and reaching a consensus on methods and tactics (Gawerc, 2021; Rogers, 2004) and competing policy stances and stereotypes (Hope, 2019; Nopper, 2006). Numerous instances of social movements that failed due to the failure of coalitions to form have been documented in the literature (e.g., Almeida, 2010; Ferree & Roth, 1998; Gelb & Shogan, …
