"Airbnb Go Home:" Tourism Frictions And Short-Term Rentals In New Orleans, Madeline R. Fussell

LSU Master's Theses

This thesis examines the concerns and conflicts around short-term rental (STR) properties in New Orleans neighborhoods. Using data from collected from critical discourse analysis, semi-structured interviews and social media posts, this paper analyzes the ways the city of New Orleans, residents of the city, STR hosts, and platforms like Airbnb discuss issues of safety, displacement, rising costs of living, as well as responsible STR practices. To understand the complexities of the issues people, have with short-term rental properties, this project approaches STRs from a housing and gentrification lens to understand the role these properties play within in the daily atmospheres …

Mixed (F)Ixed Messages, Lauren A. Verrett

LSU Master's Theses

Many individuals have an understanding that our lives have a timeline, and this timeline is full of objectives that we perceive as absolutes. Through personal observations it has become apparent that there are many amazing men and woman that are stagnant because they were raised to believe that meeting these goalposts are a priority. In an age of individualism, it is evident that every individual has control of their own life through their actions. However, in this same age of technology and social media, the anxiety of not meeting certain requirements or standards is even more apparent than previous generations. …

Power Structures, Michael A. Whitehead

LSU Master's Theses

Power Structures is a series of drawings and prints inspired by my fixation with the intricate utilitarian architecture and dystopian atmosphere of Louisiana’s petrochemical corridor. The architectural forms within this body of work juxtapose components of disparate industrial sites to form ruinous monuments to power and progress. The Power Structures are composites of photographs, technical drawings, and memories I have made in my time studying Cancer Alley. I introduce machined aircraft components, gate valves, and various fasteners into the architectural forms of petrochemical plants as elements of misdirection, blurring the line between reality and memory, fact and fabrication.

[Thoughts On] The Painter & The Act Of Painting, Samantha Rosado

LSU Master's Theses

In the satirical manifesto that accompanies my work, humor, and sarcasm play an important role in understanding the narrator’s tone. The information included is both factual and imagined, pulled from stories and experiences of a group of painters. My hope is to help aspiring painters develop their own rules and philosophies based on what they learn through the canon of art history. As a writer I aim to motivate those who feel under-represented in the world of fine art and craft to reject feelings of inadequacy. As an artist I make with the intention of being vulnerable and honest.

Neverending Loop, Joseph Nivens

LSU Master's Theses

The intention of NeverEnding Loop is to depict the trauma of queer adolescense contrasted by the shadow of the closet that follows LGBTQ+ children into adulthood. The reality for queer people is that coming out is a process that never ends and a task that can create a lonely existence for those that are different from the norm. The artwork aims to convey the very real and confusing struggle of finding your identity as a queer person existing in a heterosexual world.

NeverEnding Loop explores loops and cycles in short animations, sculptural forms with repeating imagery, and mixed media forms …

Assessment Of Endogenous Biomass Decay As A Source Of Precursors For Microbially-Mediated Toluene And P-Cresol Production, Samuel J. Reynolds

LSU Master's Theses

The research reported in this thesis was conducted to investigate whether protein hydrolysis associated with endogenous decay of biomass produced following the addition of a readily fermentable substrate is a potential source of precursors that can ultimately be transformed to toluene and p-cresol in environments undergoing enhanced bioremediation.

A packed column intended to represent a laboratory-scale section of an aquifer was seeded with groundwater and then supplied with molasses-amended groundwater for a two-day interval. The injected molasses concentration and surface loading rate were selected to be representative of conditions in the vicinity of injection wells at a Superfund Site …

Body/Mind:Matter, Mary Ellen Ratcliff

LSU Master's Theses

Body/Mind:Matter presents the unfiltered experiences of living in a period of momentous instability. Three life-sized figurative sculptures stage my emotional journey towards mindfulness as a direct response to the pandemic and my growing concern for our collective future. A winding network of crocheted yarns and growing vines interweave the troubled figures to signify our complex dependencies upon one another and our environment.

The condition of the encumbered bodies is a result of the worried mind. Revitalized matter proposes reconciliation by introducing a sense of hope; decaying surfaces reveal new life; fused wires hold up under immense pressure; and soft woven …

Hello Again يا اهلا A Study Of Grief, Diana Abouchacra

LSU Master's Theses

Grief is an unwanted visitor who we all come to know throughout our lifetime. Although every person reacts differently to bereavement of a loved one, almost always the lost other becomes etched into our being for the remainder of our lives (McClocklin & Lengelle, 2017). In today’s society, we are encouraged to say “Good-bye”, but what if instead, we allow ourselves to keep those who have passed on close to our hearts and say hello again? Hello Again يا اهلا is a body of work that explores my experience with grief. The artworks made for this exhibition investigate my process …

Evidence For Perchlorate-Coupled Molybdenum And Nickel Carbon Monoxide Dehydrogenase Co Oxidation And Characterization Of Novel Perchlorate-Reducing Haloarchaea, Marisa Russell Myers

LSU Doctoral Dissertations

Carbon monoxide (CO) has been exploited as a microbial energy source for much of life’s evolutionary history. A phylogenetically diverse array of microorganisms can oxidize CO using two distinct CO dehydrogenases, molybdenum-dependent (Mo-CODH) and nickel-dependent (Ni-CODH). Aerobes and facultative organisms contain Mo-CODHs which allow them to utilize oxygen as an electron acceptor in addition to alternatives such as nitrate and sulfate. Obligate anaerobic organisms contain Ni-CODHs, which oxidize CO at elevated concentrations, but cannot utilize oxygen. In systems where organic matter deposits are limited or absent, atmospheric trace gases such as CO are thought to assist in supporting the growth …

The Role Of School Sociocultural Factors On The Mental Health And Academic Competence Of Elementary Aged Children, Aijah Kai Baruti Goodwin

LSU Doctoral Dissertations

Due to the diversification of school systems, schools are being challenged to engage in more culturally responsive practices to meet the needs of diverse students. Therefore, this study utilized Gay’s (2002) model of culturally responsive teaching to assess the relationship between sociocultural factors and the academic competence and mental health of elementary-aged children. This study also aimed to investigate the mediating and moderating relationship that culturally responsive classroom practices play on children’s academic competence and mental health. One hundred thirty-one diverse parents (97.7%), and legal guardians (2.3%) with children in elementary school (M_age = 8.05) were recruited for participation …

Fan Fiction And The Trojan War: Contemporary Euripidean Perspective On The Treatment Of Enslaved Women In The Silence Of The Girls, A Thousand Ships, And For The Most Beautiful, Richard K. Sheldon

LSU Master's Theses

This study examines three contemporary novels of fan fiction, authored by women, that retell the Trojan War: Emily Hauser’s For the Most Beautiful (2016), Pat Barker’s The Silence of the Girls (2018), and Nathalie Haynes’ A Thousand Ships (2019). This study offers a reading of contemporary Homeric reception by analyzing the conversations that the novels initiate between each other, Homer’s Iliad, and Euripides’ tragedies, Hecuba (424 BCE) and Trojan Women (415 BCE). The study establishes a connection between the three authors and Euripides by treating the novels as works of fan fiction. In so doing, the study identifies …

Characterizing The Northern Hemisphere Circumpolar Vortex Through Space And Time, Nazla Bushra

LSU Doctoral Dissertations

This hemispheric-scale, steering atmospheric circulation represented by the circumpolar vortices (CPVs) are the middle- and upper-tropospheric wind belts circumnavigating the poles. Variability in the CPV area, shape, and position are important topics in geoenvironmental sciences because of the many links to environmental features. However, a means of characterizing the CPV has remained elusive. The goal of this research is to (i) identify the Northern Hemisphere CPV (NHCPV) and its morphometric characteristics, (ii) understand the daily characteristics of NHCPV area and circularity over time, (iii) identify and analyze spatiotemporal variability in the NHCPV’s centroid, and (iv) analyze how CPV features relate …

Bio-Mediated Ground Improvement For Fine-Grained Soil, Guantao Cheng

LSU Master's Theses

The research explored the use of microbially induced carbonate precipitation (MICP) to improve the mechanical properties of fine-grained soil and rapidly repair soil cracks on embankment slopes. Slope failures are often induced by surface cracks on the embankment slopes. To date, most rapid repair methods for slope failures (e.g., geosynthetics, soil nails, plastic pins, and lime treatment, etc.) involve large earthwork, special installation equipment, and unique construction processes, which may require extended construction time, disturb traffic, or increase the total construction cost. This research explored the feasibility of using bio-cement (MICP) to improve soil mechanical properties, seal the soil cracks, …

Hydrometeorological Responses To Abrupt Land Surface Change Following Hurricane Michael, Shannon Alexis Nelson

LSU Master's Theses

While many of the destructive environmental conditions associated with tropical cyclones are well recognized, tropical cyclone-induced defoliation, a reduction in green leaves and mature vegetation, has been largely overlooked as a source of environmental stress following tropical cyclone passage. The land surface change associated with defoliation reduces evapotranspiration and shade, thus altering boundary layer moisture and energy fluxes that drive the local water cycle, for many months after tropical cyclone passage. Understanding the potential for any hydrometeorological impacts arising from such abrupt land surface change is important for guiding future post-hurricane preparedness and recovery planning in coastal communities.

The United States Department of Agriculture’s Summer Food Service Program (SFSP) provided children under the age of 18 in low-income areas 145 million free meals in 2018 through summer feeding sites. Food safety issues arise for Louisiana feeding sites due to time-temperature controlled foods served, weather patterns in Louisiana, seasonal staff and short operation time, and lack of equipment. The purpose of this study was to assess food safety practices at Louisiana feeding sites through observational study with intention to compare food practices at institutional and noninstitutional sites. A rubric following USDA food safety guidelines based on categories: hot holding, …

Musical Gesture Through The Human Computer Interface: An Investigation Using Information Theory, Michael Vincent Blandino

LSU Doctoral Dissertations

This study applies information theory to investigate human ability to communicate using continuous control sensors with a particular focus on informing the design of digital musical instruments. There is an active practice of building and evaluating such instruments, for instance, in the New Interfaces for Musical Expression (NIME) conference community. The fidelity of the instruments can depend on the included sensors, and although much anecdotal evidence and craft experience informs the use of these sensors, relatively little is known about the ability of humans to control them accurately. This dissertation addresses this issue and related concerns, including continuous control performance …

Single-Well Gas-Assisted Gravity Draining Process For Oil Recovery, Dandina N. Rao, Bikash D. Saikia

College of Engineering Patents

Disclosed is a less expensive, more efficient process for enhanced oil recovery, particularly useful in high cost environments such as offshore. This process is known as single well gas assisted gravity drainage (SW-GAGD). The process comprises the steps of drilling from a single wellbore one or more horizontal laterals near the bottom of a payzone and injecting a fluid displacer such as nitrogen or carbon dioxide through injection points. The injectant sweeps the oil and other produced fluids in the reservoir towards other producing perforations in the single well.

Virtual Worlds: Social Interactions Among Online Gamers Through Voice Chat, Omar Bradley Ictech Ii

LSU Doctoral Dissertations

Online gaming scholarship has rarely focused on the micro sociological aspects of virtual worlds as much of the research on online games is undertaken by psychologists and scholars in other fields. When a sociological lens is employed in analyzing social interactions that occur in virtual worlds, new understandings of social phenomena in virtual worlds can come to light. My research draws upon multiple sociological theories to make sense of data collect via in-depth interviews and participant observations in an attempt to understand how voice chat influences relationship formation and maintenance, gender relations among online gamers, and how online gamers use …

Modeling Hydraulic Fracturing Initiation And Propagation In Porous Rock Formationsl, Chang Huang

LSU Doctoral Dissertations

Hydraulic fracturing has long been introduced to the oil and gas industry since the early nineteenth century for both reservoir characterization and reservoir stimulation. Despite the progress made in the last two decades, many challenges still have not been tackled regarding not only the propagation problem but also the initiation problem due to its complexity. The dissertation is divided into two stages, i.e., before and after fracture initiation. The first stage of the research aimed at improving the accuracy in solving the poro-mechanical response of wellbore during fluid injection before a tensile fracture occurs, which is crucial to determine the …

Delivering Bad News: Crisis Communication Methods In Academic Libraries, Brittany O'Neill, Rebecca Kelley

Faculty Publications

This exploratory study analyzed the specific crisis communication methods of academic libraries. A survey was sent to library staff at Association of Research Libraries-member colleges and universities to describe if, who, when, and how they communicated bad news to their stakeholders for major, minor, and emerging crises. The findings show that respondents used multiple communication strategies, which varied based on the crisis. The data show that libraries communicated journal and database cancellations and health and safety emergencies more slowly than access issues and were more likely not to communicate those crises at all. Respondents also more frequently chose to communicate …

Performance Measurements Within Asynchronous Task-Based Runtime Systems: A Double White Dwarf Merger As An Application, Patrick Diehl, Dominic Marcello, Parsa Amini, Hartmut Kaiser, Sagiv Shiber, Geoffrey C. Clayton, Juhan Frank, Gregor Dais, Dirk Pfluger, David Eder, Alice Koniges, Kevin Huck

Faculty Publications

Analyzing performance within asynchronous many-task-based runtime systems is challenging because millions of tasks are launched concurrently. Especially for long-term runs, the amount of data collected becomes overwhelming. We study HPX and its performance-counter framework and autonomic performance environment for Exascale to collect performance data and energy consumption. We added HPX application-specific performance counters to the Octo-Tiger full 3-D adaptive multigrid code astrophysics application. This enables the combined visualization of physical and performance data to highlight bottlenecks with respect to different solvers. We examine the overhead introduced by these measurements, which is around 1%, with respect to the overall application runtime. …

Citations Versus Expert Opinions: Citation Analysis Of Featured Reviews Of The American Mathematical Society, Lawrence Smolinsky, Daniel S. Sage, Aaron J. Lercher, Aaron Cao

Faculty Publications

Peer review and citation metrics are two means of gauging the value of scientific research, but the lack of publicly available peer review data makes the comparison of these methods difficult. Mathematics can serve as a useful laboratory for considering these questions because as an exact science, there is a narrow range of reasons for citations. In mathematics, virtually all published articles are post-publication reviewed by mathematicians in Mathematical Reviews (MathSciNet) and so the data set was essentially the Web of Science mathematics publications from 1993 to 2004. For a decade, especially important articles were singled out in Mathematical Reviews …

Conceptus Metabolomic Profiling Reveals Stage-Specific Phenotypes Leading Up To Pregnancy Recognition In Cattle†, Constantine A. Simintiras, José M. Sánchez, Michael Mcdonald, Elena O'Callaghan, Ahmed A. Aburima, Patrick Lonergan

Faculty Publications

Reproductive efficiency in livestock is a major driver of sustainable food production. The poorly understood process of ruminant conceptus elongation (a) prerequisites maternal pregnancy recognition, (b) is essential to successful pregnancy establishment, and (c) coincides with a period of significant conceptus mortality. Conceptuses at five key developmental stages between Days 8-16 were recovered and cultured in vitro for 6 h prior to conditioned media analysis by untargeted ultrahigh-performance liquid chromatography tandem mass spectroscopy. This global temporal biochemical interrogation of the ex situ bovine conceptus unearths two antithetical stage-specific metabolic phenotypes during tubular (metabolically retentive) vs. filamentous (secretory) development. Moreover, the …
