Examining The Effectiveness Of “Turn Around Don’T Drown”, Chance D. Bryant

LSU Master's Theses

Extreme heat is the deadliest weather hazard in the U.S. Flooding is the second worst, and flash flooding is the deadliest form of flooding. The nature of these flood deaths contains a human element that deserves greater study. Since 2004, the National Weather Service has attempted to educate the public with its slogan, ``Turn Around Don’t Drown". Vehicle related mortality rates in Texas since 1996 were examined to answer the question of whether ``Turn Around Don’t Drown" has been effective. The slogan has a large footprint on the social media platform Twitter, with most of the Tweets coming from private …

What The Shell? The Zooarchaeology Of Cerro San Isidro, Peru, Monica Fenton

LSU Master's Theses

Zooarchaeologists have documented the importance of marine resources in the ancient Andes, and the first field season at Cerro San Isidro (Ancash, Peru) proves no different. The multi- component hilltop archaeological complex lies in the agriculturally rich Moro Pocket of the middle Nepeña Valley, at least an eight-hour walk from the ocean on the north-central coast. Between June and August 2019, members of the Proyecto de Investigación Arqueológica Cerro San Isidro carried out the first scientific excavations at this important ancient human settlement. Block excavations focused on a hypothesized elite compound, documenting intermittent occupations from the Late Formative (c. 600 …

Blue Carbon In South Florida's Mangroves: The Role Of Large Roots And Necromass, Zoë I. Shribman

LSU Master's Theses

Blue carbon sequestration and storage in mangroves largely result from belowground biomass allocation in response to flooded anaerobic soil conditions and nutrient availability. Biomass allocation to belowground roots is a major driver of mangrove soil formation and organic matter accumulation leading to blue carbon storage potential. Belowground biomass sampling in mangroves is labor intensive, limiting data availability on biomass stocks, particularly for large roots (>20 mm diameter) and necromass (dead roots). The mangrove nutrient model (NUMAN) uses mostly literature values to parameterize a soil cohort approach to simulate depth distribution of root mass and organic carbon concentration. We evaluated …

Causes And Characteristics Of Electrical Resistivity Variability In Shallow (<4 M) Soils In Taylor Valley, East Antarctica, William S. Gutterman

LSU Master's Theses

The McMurdo Dry Valleys are the largest ice-free region in Antarctica and are characterized as a polar desert environment. Soils in the region are typically very dry (<1% soil water by weight) and remain frozen for most of the year. Increases in air temperature and incoming solar radiation during the austral summer generate meltwater from glaciers, ground ice, and snow patches supplying moisture to soils and altering the physical and chemical makeup of the subsurface. Previous studies have utilized airborne electromagnetic surveys (AEM) to analyze groundwater systems in the deep subsurface but have not yet examined soil moisture in the shallow (<4 m) subsurface. Here, I used electrical resistivity data from two AEM surveys (2011 and 2018) and soil geochemical data from three transects to characterize the spatial heterogeneity of soil properties in the near-subsurface of lower Taylor Valley. Soil resistivities from 2011 and 2018 range from 33.2 Ωm to 3535 Ωm with low elevations of <100 meters above sea level (masl) typically displaying the lowest resistivities and high elevations displaying greater resistivities. Liquid brine fractions were empirically estimated from electrical resistivity values using Archie’s Law and range from 0.3% to 68.2% for soils with resistivities <200 Ωm. Additionally, soil transect data show greater percentages of fine-grained sediments (<63 µm) exist at elevations <100 masl where soil resistivities begin decreasing. Resistivity variability in the subsurface is ultimately controlled by the site history, local and regional climate, soil salinity, soil moisture, soil lithology.

A Semiotic Approach To Visual Analysis Of Dress: Symbolic Communication Of Clothing Color, Cut, And Composition Through The French Film Costumes Of Anaïs Romand, Leigh Danielle Honeycutt

LSU Master's Theses

This study examines the communicative role of clothing in film. Using the skillful costume canvas of French designer Anaïs Romand, we explore the possible visual messages and potential cultural and linguistic meanings that clothing choice conveys. This analysis uses Roland Barthes’ Theory of the “Five Codes” from his book S/Z as well as psychological sources about color analysis as its methodological basis. Images from each of the five period piece films were chosen and analyzed using semiotics. The costumes in all five films chosen for analysis were designed under the direction of Anaïs Romand and were all either nominated for, …

A Geospatial And Statistical Analysis Of Dropout In Louisiana Public High Schools, Michael D. Stein

LSU Master's Theses

Students dropping out of high school is a nationwide problem, plaguing communities and often greatly reducing the prospects of a quality life for those students who do not complete their high school educations. Louisiana consistently has among the highest public high school dropout rates in the United States, and often the highest. This geospatial and statistical study aims to identify the factors that correlate with high school dropout in Louisiana public high schools, specifically, and to produce detailed maps of the dropout rates across the state to identify the schools most afflicted.

Extensive school-level data from five academic years (2014-15 …

Environmental Perception In Colombia's Páramo Protected Areas, Juliana Delgado

LSU Master's Theses

This thesis analyzes the gap between farmers' environmental perceptions in Téquita, a small village in Colombia, and the definition of protected areas has led to a conflict for the use of natural resources. I examine if the protected area's policies have dealt with the social and ecological issues in the páramos and recognized the social construction of the landscape, farmers' identities, and their interpretations about work and land. The case study focuses on Güina High Mountain in the Guantiva-La Rusia páramo complex, which recently the Colombian government declared as a protected area. In light of anthropologist Tim Ingold's meaning of …

Non-Destructive Trace Element Analysis Of Burials From Moho Cay, Belize, April Alyce Walton

LSU Master's Theses

The study of skeletal material macroscopically and microscopically can yield a plethora of information about interments’ lives. Studying bones at an elemental level can provide further details regarding dietary habits, residency, and migration patterns, which are important areas of research for Maya archaeology. Currently, research on bone composition is conducted through destructive methods, especially for archaeological bone. The use of non-destructive methods for testing bone composition such as with a portable x-ray fluorescence machine can also be suitable for the study of archaeological bone. This study has two main goals: to understand the interments' lives through strontium trace element and …

Ancient Pottery Making At Cerro San Isidro, Nepeña Valley, Peru, Kaitlyn M. Lowrance

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 …

Penguins Past And Present: Trace Elements, Stable Isotopes, And Population Dynamics In Antarctic And Sub-Antarctic Penguins And Seals, Allyson K. Kristan

LSU Master's Theses

Antarctica and the sub-Antarctic are remote regions where the impacts from climate change and anthropogenic activities are increasingly apparent. Previous studies show that the Antarctic is warming and has been affected by anthropogenic contaminants. Marine predators such as penguins and seals are commonly used in these regions as sentinels of ecosystem health as predator tissues can be used as non-invasive proxies of diet, population trends, and contaminant exposure. This thesis includes two separate studies which investigate the influence of climate change and human activity on Antarctic and sub-Antarctic ecosystems. First, Adelie penguin (Pygoscelis adeliae) eggshell samples were collected …

Through these interviews, we seek to establish the importance of costume in reflecting and constructing a sense of community within the group.

While the existing literature focuses on the history of second line parades and their importance in Louisiana’s culture, this research intends to explore costume’s meaning and significance. The purpose of this work is to complement the existing literature in …

Effects Of Historical Land-Use Change On Surface Runoff And Flooding In The Amite River Basin, Louisiana, Usa Using Coupled 1d/2d Hec-Ras–Hec-Hms Hydrological Modeling, Alexandre G. H. Cowles

LSU Master's Theses

The Amite River Basin is a largely rural watershed spanning parts of four counties in southern Mississippi and seven parishes in southeast Louisiana, with basinwide imperviousness increasing from 0.82% in 1938 to 3.85% in 2016. The Basin has been the subject of significant research interest since catastrophic flooding in 2016 caused 13 deaths and widespread damages. Rapid development in recent decades has led to an expansion of impervious surfaces in Baton Rouge and surrounding areas, encroaching on floodplains and wetlands. At the basin scale, differences in flooding due to impervious cover changes were found to be somewhat limited, particularly along …

"The Face Of The Agency": Interviews With Death Investigators In South Louisiana, Natalie H. King

LSU Master's Theses

According to the American Board of Medicolegal Death Investigators, “the role of the medicolegal death investigator is to investigate any death that falls under the jurisdiction of the medical examiner or coroner, including all suspicious, violent, unexplained and unexpected deaths” (American Board of Medicolegal Death Investigators [ABMDI], n.d.). As such, a death investigator has a job that is highly intense and stressful at a level similar to that of doctors, nurses, emergency medical technicians (EMTs), and firefighters. The majority of the literature written about death investigators focuses on procedural issues, while there seemingly is a lack of literature focused on …

Voice Therapy: Racial Disparities In Adherence And Clinically Significant Outcomes, Amber D. Burks

LSU Master's Theses

Voice therapy is evidence-based, behavioral intervention that can reduce functional and organic voice disorders. Despite its proven effectiveness, non-adherence to voice therapy is still an issue. Research shows that an estimated 65% of patients who initiate voice therapy drop out before reaching therapeutic goals. Voice therapy outcomes are largely dependent on patients’ adherence to treatment regimens, but there is limited information concerning factors that may be associated with voice therapy adherence and therapeutic outcomes for patients who successfully complete voice therapy.

The purpose of this study was to investigate which demographic factors could be associated with higher adherence rates to …

Sea-Level Rise And Settlement At Ta’Ab Nuk Na, Belize: Analyses Of Marine Sediment From The I-Line, 4m Transect, Conner B. Flynt

LSU Master's Theses

The ancient Maya of Mesoamerica created a culture with writing, religion, and vast trade networks. These trade networks are evident on the southern coast of Belize, where archaeologists have found sites dedicated to salt making. One of these sites, Ta’ab Nuk Na, was the subject of this thesis. Sediment and charcoal samples were collected from this site by the Underwater Maya Research Group led by Heather McKillop and E. Cory Sills. For my thesis research, I subjected these samples and components within them to loss-on ignition, radiometric dating, and microscopic analysis. Loss-on ignition was used to ascertain organic material percentage …

The Bioarchaeology Of The Lake St. Agnes Mound (16av26) Site: Exploring Diet From Fragmentary Remains, Kenneth Tremblay

LSU Master's Theses

The Lake St. Agnes Mound (16AV26) site, located in central Louisiana, is composed of two, temporally distinct burial components; one, a Coles Creek period component, at the base of the mound (~780-880 CE), and the other, a Plaquemine subperiod component, at its apex (~1400 CE). These burials, though heavily fragmented, commingled, and representing small sample sizes, are valuable for studying the transition to agriculture in the Lower Mississippi River Valley. It is now clear that for the Coles Creek period, maize was likely only a ceremonial crop rather than a staple food source (Kidder, 1993; Listi, 2011). The reliance on …

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …

Using The Seventh Rib Length And Depth Measurements As A Method To Estimate Ancestry And Sex In Adults, Alexandria M. Amaki

LSU Master's Theses

This study tested the correlation of dimensions of the left seventh rib (L7) to ancestry and sex in adult humans. The first hypothesis, based on Bergmann’s theory, is that Black (African-American) individuals will have smaller L7 dimensions than White individuals (Americans of primarily European descent). The second hypothesis is that males, due to sexual dimorphism, will have larger ribs than females. 299 individuals from the Hamann-Todd Skeletal Collection were used in the study, approximately evenly distributed among sex and ancestry groups. Five variables were examined, including three measurements (length, width, and width point), and two calculations (area and ratio). A …

Mapping Louisiana's Missing: Spatiotemporal Profiling Of Louisiana's Missing Persons- An Experimental Application Of Geographic Information Systems And Forensic Anthropology, Liam J. Johnson

LSU Master's Theses

The growing number of unresolved unidentified and missing persons cases in the United States is this nation’s ‘silent mass disaster’ (Ritters, 2007). In addition to contextualizing biocultural traits of these cases, forensic anthropologists are uniquely qualified to address this underrecognized humanitarian crisis due to their proven ability to bridge conflicting stakeholders in often complex sociopolitical environments and to create improved opportunities for community collaboration. This project explores local and state demographic trends of missing persons cases and how this information can be used to assist investigative agencies with their missing population, analyzes gaps in identification data, and selects optimal locations …

Typing Tornadoes By Storm Mode In The Southeast United States, Marisa R. Karpinski

LSU Master's Theses

Existing work has noted three major, radar-derived, storm modes associated with tornadoes: supercell, quasi-linear convective systems, and tropical systems. I examine the long-term frequency and seasonality of each storm mode between 1996 and 2017 in the Southeast United States. The Southeast is chosen as a focus for this work due to its well-known and unique combination of tornado vulnerability and exposure. Expanding our knowledge of the radar presentation of tornado-producing thunderstorms in this region could assist in the operational interpretation of these events. In this study, a climatology of F/EF1+ tornadoes (1996 - 2017) is generated for the study area …

The Yangtze River has been the primary support of the resources and transportation of China. Its basin covers an area of 1.8 million square kilometers. The Three Gorges Dam and Reservoir on the Yangtze River is one of the world's largest dams. After the dam construction in 1997, the reservoir started injecting the reservoir to a size of over 600 km². The influence caused by the dam and reservoir on the river system has been overwhelming and destructive. The possible influence of this vast water body and the operation to maintain this waterbody's size and water level on …

Do Ground Layer Microhabitats In Old-Growth Pine Savanna Influence Recruitment Of Longleaf Pine?, Matthew Blanchard

LSU Master's Theses

Savanna tree populations typically share two demographic characteristics, high mortality of juvenile stages and low mortality of established trees. Juvenile savanna tree species escape demographic bottlenecks when they reach a safe size and annual mortality becomes low. Longleaf pine (Pinus palustris Mill.) is the dominant tree species in pine savannas of the southeastern United States. The seeds and juvenile seedlings experience bottlenecks to recruitment to a safe size, the grass stage. Low intensity, frequent savanna fires facilitate establishment of seedlings, but also kill juvenile seedlings that have not grown sufficient above ground biomass. We hypothesized that juvenile seedlings escape the …

Reconsidering The Obstetrical Dilemma: Correlations Between Head And Pelvic Size, Kelsey Catrice Fox

LSU Master's Theses

The Obstetrical Dilemma (OD) theory has become canon in biological anthropology. The OD posits that i] dystocia results from bipedal mothers and encephalized infants, ii] contrasting selection for bipedality and obstetrics hinders locomotive efficiency, and iii] the contradicting requirement of the fetus being small enough to pass through the birth canal yet being cognitively advanced enough to cling to its mother after birth. Females, theoretically, exhibit deficient gait efficiency for the sake of successful childbirth. An obstetric advantage theory has been posited where taller individuals with a larger head size have larger pelves. If the distance between the acetabulae increases …

The Strange Death Of American Democracy: Judicial Supremacy And The New Constitutional Politics, 1910-1916, Logan Istre

LSU Master's Theses

American constitutional politics reached a crisis point during the Progressive Era. At the center of the crisis was the question as to what the Constitution meant and who had the final word in interpreting it: The Supreme Court or the People of the United States. That fundamental question came to a head in the presidential election of 1912. The result of that contest was the confirmation of judicial supremacy in constitutional interpretation and a mortal blow the nation’s traditional popular constitutional politics. The ensuring consensus of judicial supremacy has defined the nation’s constitutional politics since, which has resulted in the …

This …

Water, Waste, And Race: Designing For Change On The Shelby County Landfill, Elizabeth Peterson

LSU Master's Theses

Historically, landfills have been viewed through an environmental lens as sites for technical remediation, employing scientific or engineering strategies for testing, mitigation and capping. They are more rarely viewed as cultural landscapes, places with histories of habitation and use, or as potential sites for design. This thesis investigation examines the Shelby County Landfill in Memphis, Tennessee from a cultural landscape perspective, opening up a dialog and opportunity to think about this site and other waste sites in a more layered and culturally rich way.

This research contributes to discussions within the field of landscape architecture that present waste landscapes as …
