17O-excess is a relatively new water isotope parameter that could potentially provide useful information about the hydrological cycle. Previous works focusing on 17O-excess in polar regions suggest that it primarily tracks moisture source relative humidity, but little is known about how to interpret 17O-excess data in lower latitudes. Here we present quasi-hourly triple oxygen isotope data of precipitation collected from two tropical cyclones in Texas and Louisiana in 2020 to understand the impacts of environmental and meteorological processes on the 17O-excess of low-to mid-latitude precipitation. We find that at both hourly timescales and the event scale, 17O-excess is strongly correlated …
Effects Of Social Media Use Disparities On Community Resilience To Disasters, Kejin Wang
Effects Of Social Media Use Disparities On Community Resilience To Disasters, Kejin Wang
LSU Doctoral Dissertations
With the rapid development of social media, many researchers chose to use social media data to conduct studies of disaster resilience. This dissertation addresses three fundamental challenges related to social media use and disaster resilience analysis including: how the spatial analysis scale affects the results of social media use disparity and its impacts on disaster resilience; how different vulnerability and resilience measurement methods can generate very different results; and how social media use disparity can be identified to help improve the fairness of AI-based emergency rescue model development. Therefore, the first part of the dissertation measured the relationships between disparities …
"In The Footsteps Of Hercules": The Influence Of Classical Antiquity On Eighteenth-Century Militaries, Scott Madere
"In The Footsteps Of Hercules": The Influence Of Classical Antiquity On Eighteenth-Century Militaries, Scott Madere
LSU Doctoral Dissertations
This project examines the pervasive influence of ancient Roman and Greek figures, historical events, literature, and military methods on the leaders and practitioners of eighteenth-century warfare. Rulers, generals, military theorists, and officers frequently consulted classical histories and literature for solutions to the common military problems of the period – tactical, operational, and strategic – showing remarkable faith in ancient military methods despite their growing dependence on gunpowder weaponry and related technologies. This dissertation examines why this was the case and concludes that classical antiquity not only maintained the credibility of its wisdom in the context of modern warfare, but also …

In the field of natural language processing (NLP), there have been various pre-training language models in recent years, with question answering systems gaining significant attention. However, as algorithms, data, and computing power advance, the issue of increasingly larger models and a growing number of parameters has surfaced. Consequently, model training has become more costly and less efficient. To enhance the efficiency and accuracy of the training process while reducing the model volume, this paper proposes a first-order pruning model PAL-BERT based on the ALBERT model according to the characteristics of question-answering (QA) system and language model. Firstly, a first-order network …

Mangroves are one of the most carbon-dense forests on the Earth and have been highlighted as key ecosystems for climate change mitigation and adaptation. Hundreds of studies have investigated how mangroves fix, transform, store, and export carbon. Here, we review and synthesize the previously known and emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood accumulation, soil carbon sequestration, root and litterfall production), transformations (food web transfer through herbivory, decomposition), and losses (respiration as CO2 and CH4, litterfall export, particulate and dissolved carbon export). We then review the technologies available to measure carbon fluxes in mangroves, their potential, …

Humans have profoundly impacted the distribution of plant and animal species over thousands of years. The most direct example of these effects is human-mediated movement of individuals, either through translocation of individuals within their range or through the introduction of species to new habitats. While human involvement may be suspected in species with obvious range disjunctions, it can be difficult to detect natural versus human-mediated dispersal events for populations at the edge of a species' range, and this uncertainty muddles how we understand the evolutionary history of populations and broad biogeographical patterns. Studies combining genetic data with archaeological, linguistic and …
Gendered Perceptions And Socio-Economic And Spatial Determinants Of Fear Of Crime: An Empirical Analysis In Szczecin, Poland, Natalia Sypion, Arkadiusz Kołodziej, Michael Leitner, Marek Dutkowski
Gendered Perceptions And Socio-Economic And Spatial Determinants Of Fear Of Crime: An Empirical Analysis In Szczecin, Poland, Natalia Sypion, Arkadiusz Kołodziej, Michael Leitner, Marek Dutkowski
Faculty Publications
The study of the fear of crime phenomenon provides a socially and politically important research question. Many studies show that gender differentiates the fear of crime, which is why we examine this phenomenon in a spatial perspective. The female versus male perspective of feelings of safety in residential areas were significantly different. The research was carried out using the CAWI technique in the city of Szczecin, in Poland (n=346). The research also examined which factors influenced the fear of crime the most: darkness, socio-economic characteristics, type of violations, number of registered crimes, or the assessment of police work. The research …

As a source of protein and other nutrients for a growing population, edible insect production offers environmental and sustainability advantages over traditional meat production. Although around 2 billion people consume insects worldwide, Western consumers are still reluctant to practice entomophagy, hindered largely by neophobia and negative emotions. In addition to sensory quality and safety, an informational component may be crucial to consumers’ decision making involving insect consumption. In this study, three different information types, namely text, image, and a tangible product, were used to convey information about chocolate chip cookies (CCCs) containing cricket flour. The nature of the information was …

Background: Gamification represents a promising approach for facilitating positive social interactions among groups of individuals and is increasingly being leveraged in physical activity (PA) interventions to promote enhanced intervention engagement and PA outcomes. Although African American (AA) adults experience disparities associated with health conditions that can be ameliorated with increased PA, little is known about how best to culturally target PA gamification strategies for this population. The purpose of this study was to gather perspectives from AA adults residing in the Southeast United States and subsequently identify themes to help inform the cultural adaptation of an existing electronic and mobile …
Death, Dreaming, And Diaspora: Achieving Orientation Through Afro-Spirituality, Liz Johnston, Jaime Elizabeth Johnston
Death, Dreaming, And Diaspora: Achieving Orientation Through Afro-Spirituality, Liz Johnston, Jaime Elizabeth Johnston
LSU Doctoral Dissertations
Enslavement, colonization, and the systems that uphold racial injustice were and still are a series of new, unfathomable, and challenging experiences that prompt individuals within the diaspora to seek orientation. How does a human cope with centuries of attempts at the systematic destruction of their humanity, culture, and identity? How can they reclaim that identity, especially when so much of it seems lost? I address these questions by utilizing texts from the expansive body of work regarding ethnographic-historical-religious studies on Afro-spiritual practices to better analyze instances in literature in the ongoing practice of diasporic orientation. In this project, I argue …
The Relationship Between The Saharan Air Layer, Convective Environmental Conditions, And Precipitation In Puerto Rico, P. W. Miller, C. Ramseyer
The Relationship Between The Saharan Air Layer, Convective Environmental Conditions, And Precipitation In Puerto Rico, P. W. Miller, C. Ramseyer
Faculty Publications
The Saharan Air Layer (SAL) is a hot, dry, and dust-laden feature that advects large concentrations of dust across the Atlantic annually to destination regions in the Americas and Caribbean. However, recent work has suggested the SAL may be a contributing factor to high-impact drought in the Caribbean basin. While the SAL's characteristic dust loadings have been the focus of much previous research, fewer efforts have holistically engaged the co-evolution of the dust plume, its associated convective environment, and resultant rainfall in Caribbean islands. This study employs a self-organizing map (SOM) classification to identify the common trans-Atlantic dust transport typologies …

Time, Place, & Purpose: The Performance Of Creole Identity In Louisiana, Rachel N. Aker
LSU Doctoral Dissertations
Though much of the early development of Louisiana Creole culture can be found in New Orleans, the culture spread and continued to grow throughout the rest of South Louisiana in both similar and different ways. Expanding beyond Joseph Roach’s treatment of Creole cultural performances in New Orleans in Cities of the Dead (1996) and journeying across land and water, this project identifies more Creole cultural performance as they emerge across place and time. I present Louisiana and the Gulf South as a kind of inland archipelago, with the currents of culture-creation moving in and around distinct community enclaves. The flow …

One of the world’s largest “blue carbon” ecosystems, Louisiana’s tidal wetlands on the US Gulf of Mexico coast, is rapidly being lost. Louisiana’s strong legal, regulatory, and monitoring framework, developed for one of the world’s largest tidal wetland systems, provides an opportunity for a programmatic approach to blue carbon accreditation to support restoration of these ecologically and economically important tidal wetlands. Louisiana’s coastal wetlands span ∼1.4 million ha and accumulate 5.5–7.3 Tg yr−1 of blue carbon (organic carbon), ∼6%–8% of tidal marsh blue carbon accumulation globally. Louisiana has a favorable governance framework to advance blue carbon accreditation, due to …

Environmental History In Focus, Kennon H. Keiser Jr.
Civil War Book Review
The book reviews in this winter 2024 issue of the Civil War Book Review emphasize the role of the environment during the Civil War Era. While our two feature essays take us out of the realm of environmental history and into the world of politics, the primary focus of this winter issue is the role of nature in history. In recent years, historians have added to our knowledge of the environment’s role in the past. Nowhere is this more clear than in the Civil War Era. As historian Stephen Berry explained, “Like the Columbian Exchange, the Civil War was a …
The Key To The Shenandoah Valley: Geography And The Civil War Struggle For Winchester, Johnathan M. Ward
The Key To The Shenandoah Valley: Geography And The Civil War Struggle For Winchester, Johnathan M. Ward
Civil War Book Review
The Key to the Shenandoah Valley offers a substantial military study of the topographical and environmental features surrounding the town of Winchester, Virginia during the Civil War. Edward McCaul focuses on six specific battles for control over the town of Winchester, but he examines these military struggles in a much larger context to indicate how the geography of the Valley was crucial to Civil War strategy. In so doing, he effectively combines environmental history, military history, and political history to reveal the importance of Winchester and its terrain.

Upper Bounds For The Lagrangian Cobordism Relation On Legendrian Links, Joshua M. Sabloff, David Shea Vela-Vick, C. M.Michael Wong
Faculty Publications
Lagrangian cobordism induces a preorder on the set of Legendrian links in any contact 3–manifold. We show that any finite collection of null-homologous Legendrian links in a contact 3–manifold with a common rotation number has an upper bound with respect to the preorder. In particular, we construct an exact Lagrangian cobordism from each element of the collection to a common Legendrian link. This construction allows us to define a notion of minimal Lagrangian genus between any two null-homologous Legendrian links with a common rotation number.

Sea-level rise and settlement are investigated at Ta’ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves …
