An Oral History Of Marching Band Traditions At Historically Black Colleges And Universities, Claire Milburn

LSU Master's Theses

This study investigated the development of marching band traditions at Historically Black Colleges and Universities (HBCUs), as told through the rivalry between Southern University (SU) and Jackson State University (JSU). Marching bands at HBCUs developed a distinct style where pageantry is a priority. These bands have similar pre- and post- game traditions, and an overall spirit of fierce competition. This study is an oral history account taken from interviews with influential band directors from these programs. Band directors from JSU include Dowell Taylor, Paul Adams, Lewis Liddell, and Lowell Hollinger. These band directors all have established reputations as innovators and …

The Generalization Of Fear Condition Between Viewed And Imagined Percepts, Lauryn Michelle Burleigh

LSU Master's Theses

Mental images can provoke intense emotional states (Holmes & Matthews, 2010). Imagery and perception have common neural and physiological mechanisms, including activation of the early visual areas (Albers et al., 2013). We tested the prediction that individuals can acquire fear to imagined percepts and if this fear transfers to viewing percepts, using fMRI and self-reported measures to determine participants’ fear. The participants completed a task in which they viewed and imagined two stimuli, and were fear conditioned when imagining the CS+. Participants are only told that mild electrical stimulation will be paired with one of the stimuli, but not which …

The growth of kid meat goats and their carcass and meat characteristics with monensin sodium or decoquinate coccidiostats in feed were studied. Seventy-three goats of various breeds were divided into six groups with the treatments of control, monensin and decoquinate. Half of the goats were harvested at day 45 and the rest at day 60. The second harvest monensin group had a larger percentage of the goat carcass as the hind leg (P

Supplementation of permanent pasture with sunn hemp forage or concentrate feed were compared for influences on growth, carcass traits, and meat properties of kid meat goats. Goats …

Suspended Sediment Transport Revealed By Patterns In Turbidity And Electrical Conductivity Curves In Three Cave Systems In Missouri, Usa., Caroline M. Mierzejewski

LSU Master's Theses

In cave streams, the movement of sediment as suspended and bed loads are linked to the occurrence of precipitation events on the surface. During precipitation events, the discharge of the streams in the basin increases. As those surface streams flow into cave streams via sinkholes or fissures, the discharge in cave streams increase. In addition to changes in discharge, the response of the surface and cave streams to precipitation include changes in turbidity and electrical conductivity of the stream water.

Changes in turbidity (Tu), electrical conductivity (EC), and discharge (Q) of water in the cave stream can be used to …

Ale Beer Containing Free And Immobilized Lactobacillus Brevis, A Potential Delivery System For Probiotics, Kriza Faye Albacite Calumba

LSU Master's Theses

Probiotic products can improve gastrointestinal health and probiotics in ale beer may be attractive to health-conscious consumers. However, the alcohol in beer may decrease probiotic viability. A powder produced from durian fruit (Durio zibethinus) rind, a by-product that is currently unutilized, contains large amounts of fiber which can be used to immobilize probiotics. The objective of this study was to produce ale beer with free Lactobacillus brevis (FLB) and immobilized cells (ILB) on durian rind powder (DRP) as a potential delivery system for probiotics. L. brevis was immobilized in DRP then the morphology of FLB and ILB was …

American Waste, Jason Allen Christian

LSU Master's Theses

American Waste is an interlinking story cycle told in the first person by a character called Rice. The stories follow Rice from his childhood (in rural Oklahoma) into adulthood, first when lives in a “punk house” with other young punk rockers in Oklahoma City, and later as he travels by freight train around the country. While he travels he reports on what he sees and experiences in the subculture that he is part of, whose members are called gutter punks and crusties. Theirs is a lifestyle bent on risk and adventure and also often plagued with drug and alcohol addiction. …

Multi-Purposeful Water Design For Monte Sano Park In Baton Rouge, Yuta Masakane

LSU Master's Theses

Today, water-related disasters, including hurricanes, flood, and stormwater surge, are occurring more frequently than in the past due to extreme weather brought by climate change all over the world. In August 2016, Baton Rouge had a historic heavy rain which brought flood and negative economic impacts specifically on the north Baton Rouge area. To mitigate the negative impact of future flooding, in Monte Sano Park and its neighborhoods in north Baton Rouge, it would be helpful to implement green infrastructure which utilizes natural infiltration process of soils and plants to slow, store, and treat the stormwater as well as enhances …

A Retrospective Analysis And Method Validation Of Postmortem Interval Estimation In Louisiana, Sophia Reck

LSU Master's Theses

Forensic anthropologists are often called upon to assess the postmortem interval (PMI; i.e. time since death) of remains in varying states of decomposition and skeletonization. These assessments rely on familiarity with general taphonomic sequences and processes, in addition to experience with how these processes present in local environments and conditions. Assessment using such qualitative methods is a subjective process. Therefore, some researchers have developed formulae whose purpose is to estimate PMI in an objective format. In these instances, the resultant PMI estimation formulae were developed using local data and therefore have the potential for local applicability. Additionally, for some regions, …

Twitter Use In Hurricane Isaac And Its Implications To Disaster Resilience, Kejin Wang

LSU Master's Theses

Disaster Resilience is the capacity of a community to ‘bounce back’ from disastrous events. Most studies rely on traditional data such as census data to study community resilience. With the advent of social media era, the new data source gives us an opportunity to explore the application of Twitter data to better understand disaster resilience. A research question is: does Twitter use correlate with disaster resilience? In other words, will communities with more Twitter users be more resilient to disasters, presumably because they are more likely to be better informed? The underlying issue is that if there are social and …

The New British Christianity Of C.S. Lewis, Thomas Kemp

LSU Master's Theses

The emergence of C.S. Lewis as a popular author known for Christian content during the second half of the twentieth century provides an ideal case study for the transformation of religiosity within Britain. As religious behavior shifted from institutional adherence to private experience, Lewis became a ‘popular theologian’ who represented Christianity both for Christians – who looked to him for spiritual inspiration– and for non-Christians – who treated his views as representative of contemporary Christianity. By analyzing the reception, representation, and use of Lewis (his figure and his work) throughout the twentieth-century and into the twenty-first, it becomes clear that …

Effects Of Dietary Sugars And Sugar Alcohols On Mortality And Thermal Tolerance In Culex Quinquefasciatus And Aedes Aegypti, Madeleine Chura

Aedes aegypti (L. 1762), the yellow fever mosquito, and Culex quinquefasciatus Say 1823, the southern house mosquito, are prevalent in tropical and subtropical areas worldwide and are responsible for the spread of a number of devastating diseases to humans and livestock. The development of new control methods, as well as continued study of mosquito biology, is vital for improving human health. This study aimed to examine the efficacy of sugar alcohols as a novel means for mosquito control, as well as how sugar alcohols and other factors are involved in thermal tolerance in mosquitoes.

No-choice tests with the sugar alcohols …

Naus, Justin Greene

LSU Master's Theses

A collection of poems and nonfiction vignettes, naus entails a navigation of my experience with Tourette Syndrome and, consequently, what it can mean to have a noisy body. Rather than situate noise as a negatively construed iteration of sound, I contend that, following the work of Michel Serres, it is instead a disruption within a system, a parasitical interception, an affective force that has the potential to alter the positions and orientations of a given constellation of bodies, human or otherwise. Similar to how sound, as a verb, can be understood as “to fathom” or “to make sense of,” naus …

Estimating Sex Using The Human Mandibular Canine, Brittney Blevins

LSU Master's Theses

Sexual dimorphism can be quantified in human mandibular canines; therefore, these teeth can be used to estimate sex of skeletonized individuals. This study complements and expands previous research by comparing mesiodistal diameter (MD), buccolingual diameter (BL), and crown area of human mandibular canines. Measurements were taken from a sample of skeletal individuals from the Terry Collection (n=677), the Maxwell Museum of Anthropology Skeletal Collection (n=86), and a random sample of dental casts from the James K. Economides Orthodontic Case File (JKE, n=624), for a total study sample of 741 males and 677 females. Both left and right canines were measured, …

The Lowly Ones, Cassie Meredith Benson Grillon

LSU Master's Theses

The Lowly Ones is a collection of short stories that interrogates the meaning of beatitudes written about in Luke 6:20–23 in the Bible. The characters in these stories navigate complex moral situations that examine the meaning behind the values presented in the beatitudes: mercy, sorrow, persecution, etc. These women face the challenges of faith in surprising ways, through the notoriety of a dead sister, the fascination with a lower-class neighbor, and the mysterious purchase of an exotic bird. This collection thoroughly erases the fictitious line religion and society draw between saints and sinners.

Using Entheseal Length To Infer Locomotor Type, Antonio R. Otero

LSU Master's Theses

An enthesis is a marking (tuberosity or impression) on bone where a muscle or tendon attaches and it can be influenced by age, sex, physical activity, and muscle size. This study ascertains whether entheses, long bones, and their respective ratios can be used as an indicator for mode of locomotion in four primate species: Ateles geoffroyi (Geoffroy’s spider monkey), Colobus guereza (mantled guereza), Hylobates lar (lar gibbon), and Macaca mulatta (rhesus monkey). Seven entheses on four long bones were chosen based on importance of the muscle in relation to specific locomotor types, use in other studies, and …

Evaluation Of Reproductive Phenology And Ecology Of Eastern Wild Turkey (Meleagris Gallopavo Silvestris) Across The Southeastern United States, Nicholas W. Bakner

LSU Master's Theses

Avian reproduction is known to be a driver of population dynamics across species and systems. Behavioral decisions during incubation such as habitat selection and nest attentiveness are thought to affect nest success. The incubation process is a costly period during which individuals are sedentary and must balance survival with reproductive success and overall fitness. Current understanding of Eastern wild turkey incubation behavior provides a limited view of the incubation period. Using GPS data collected from Eastern wild turkeys (n = 220), I evaluated nest fate as it relates to recess frequency, distance travelled during recess, and habitat selection during …

Adaptation To Climate Change Through Genetic Accommodation And Assimilation Of Plastic Phenotypes, Morgan Kelly

Faculty Publications

© 2019 The Author(s) Published by the Royal Society. All rights reserved. Theory suggests that evolutionary changes in phenotypic plasticity could either hinder or facilitate evolutionary rescue in a changing climate. Nevertheless, the actual role of evolving plasticity in the responses of natural populations to climate change remains unresolved. Direct observations of evolutionary change in nature are rare, making it difficult to assess the relative contributions of changes in trait means versus changes in plasticity to climate change responses. To address this gap, this review explores several proxies that can be used to understand evolving plasticity in the context of …

Infrared Laser Ablation For Biomolecule Sampling, Kelin Wang

LSU Doctoral Dissertations

In this research, an infrared laser at a wavelength of 3 µm was used to ablate material from tissue sections for biomolecule analysis. Pulsed infrared (IR) irradiation of tissue with a focused laser beam efficiently removed biomolecules, such as proteins, enzymes, DNA, and RNA from tissue sections for further analysis. In a proteomics project, matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) was used to determine regions of interest (ROI) for laser ablation. The matrix was then washed off. By overlaying the MSI generated heat-map, the section was sampled using IR laser ablation and custom stage-control software. Two ROI were selected …

Fragments And Flânerie: Modernity, Cosmopolitanism, And The Art Of Wandering, Charla Allyn Hughes

LSU Doctoral Dissertations

This dissertation argues that wandering, whether across cities (flânerie) or across geographic regions and countries (travel), is a process of not only finding meaning but also one of confronting alienation and dislocation, conditions of the fragmentariness of modern life, which is signified by transnationalism, media, technology, and consumerism. This examination of flânerie, travel, and cosmopolitanism investigates three women writers’ representations of navigating an alienating, fragmented world—or, more simply, of the search for a sense of home and/or belonging. Transatlantic writers Mary McCarthy, Elizabeth Bishop, and Zadie Smith not only consider specific places and suspended in-betweens but also …

The Rhetoric Of Sickle Cell Anemia, Raquel Mcfarland Robvais

LSU Doctoral Dissertations

My dissertation examines the rhetorical treatment of sickle cell anemia as synecdoche, representing a preoccupation with racialized discourses of disease and the affective registers manifested in public life. From its inception SCA has taken on cultural meanings to satisfy ideological arguments about the nature of black bodies.

It has been appropriated to create “categories of difference and belonging” (Schramm et al). I examine how SCA is gathered by rhetors to serve varying ideological purposes and cultural communities. It is utilized to invite different readings that conceptualize the black body as an object of scientific experimentation, as an agent for resistance …

Development Of Sheath Blight-Resistant Breeding Lines For Southern U.S. Environments And Morphological And Genetic Survey Of Giant Salvinia Populations In Louisiana And Texas, Dominique Clark Galam

LSU Doctoral Dissertations

The southern US environment is a very conducive environment for agriculture and fisheries. Rice farming, shrimping and water related activities help drive the local economy. However, there are several factors that impede the success of these activities. Sheath blight (SB) disease caused by Rhizoctonia solani is one of the major biotic constraints to high grain yield and quality for most commercial U.S. rice varieties. Although different breeding lines with high levels of "partial resistance" have been developed none has been used directly as a commercial variety. The first research objective of this research was to identify and develop advanced breeding …

Effect Of Environmental Factors And Residual Sanitizers On Survival And Attachment Of Indicator Organism And Human Pathogens On Fresh Produce, Vijay Singh Chhetri

LSU Doctoral Dissertations

A comprehensive understanding of the behavior of microbial contaminants on produce surfaces in agricultural farms and during post-harvest activities is essential for the development of produce safety risk management strategies. Our studies investigated the survival and the attachment of E. coli on watermelon surfaces in agricultural settings with different levels of vegetation, and the effect of residual sanitizers on the survival and the attachment of E. coli O157: H7 and L. monocytogenes on spinach leaves. The attachment strength (S_R) of the E. coli cells on watermelon surfaces significantly increased (P<0.05) from 0.04 to 0.99 in the first 24 h, which was primarily due to the decrease in loosely attached population, given that the population of strongly attached cells was constant. The daily die-off rate of E. coli ranged from -0.12 …

Improving Coupled Enzyme Assays With Capillary Electrophoresis, Thu Hoai Nguyen

LSU Doctoral Dissertations

The goal of this project is to address limitations of coupled enzyme assays using capillary electrophoresis (CE). In some enzyme assays, it is ineffective to directly detect products and substrates spectroscopically (absorption or fluorescence). Coupling the enzyme-catalyzed reaction of interest with another enzyme-catalyzed reaction allows for indirect detection of product formation or substrate depletion for the target enzyme. While conventional coupled enzyme assays are facile for kinetic measurements, they can be problematic for inhibition screening due to spectral and inhibitor interferences. To address these limitations of coupled assays, CE has been used to develop enzyme assays for acetyl-coenzyme A carboxylase …

The Garbage That We Eat: Metabolizing Food-Waste In New Orleans, Louisiana, Kelly L. Haggerty

LSU Master's Theses

The 2017 Climate Action for a Resilient New Orleans report strives to divert 50 percent of waste by 2030. In the same year, waste companies had only managed to divert 5 percent of the total annual waste in Orleans Parish. Nearly a decade away from 2030, city officials have not even tested or implemented strategies to reach this goal. While city officials scramble to launch pilot projects, community and grassroots organizations center around recovering and transforming garbage and food waste. Using interviews and surveys with food-waste organizers from May to August 2018, this paper reveals that managing food-waste on a …
