Caliche As A Geologic Repository For Atmospheric Sulfate, Katie Jane Howell Jan 2006

Caliche As A Geologic Repository For Atmospheric Sulfate, Katie Jane Howell

LSU Master's Theses

Recent studies demonstrate that important information on sulfur source, oxidation pathway, transport pattern, and reaction kinetics of the oxidation reactions of reduced sulfur gases in the atmosphere may be uncovered by measuring multiple sulfur and oxygen isotope compositions of the oxidation product — secondary atmospheric sulfate (SAS). SAS from Earth’s distant past, however, is rarely preserved in the rock record because of its high solubility and small quantity. Caliche, a pedogenic carbonate formed in arid to semi-arid continental settings and common in the geologic record, could serve as a repository for ancient SAS. Two major groups of caliche samples: 1) …

Language Classification And Manipulation In Romania And Moldova, Chase Faucheux Jan 2006

Language Classification And Manipulation In Romania And Moldova, Chase Faucheux

LSU Master's Theses

Linguistic classification is a scientific methodology for categorizing the languages of the world. However, the tools and methods of linguistic classification have been used to various degrees by political entities to further nationalistic agendas. This thesis assesses the role of linguistic classification in nationality and politics, and addresses the disjunct between true linguistic classification, based on genealogical, areal, and typological features, and language designation, based on political and nationalistic motives. This thesis uses the Romanian language as a vehicle for illustrating both linguistic classification methods as well as how these methods have been manipulated for non-linguistic reasons both internally by …

Cost-Efficacy Of Wetland Preservation And Restoration In Coastal Louisiana, Christiane Aust Jan 2006

Cost-Efficacy Of Wetland Preservation And Restoration In Coastal Louisiana, Christiane Aust

LSU Master's Theses

Louisiana faces a tremendous crisis of coastal wetland loss, where an estimated 1,900 square miles of coastal land has been lost in the past century. The Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) has been the largest single source of restoration funding, providing approximately $560 million for more than 155 restoration projects since 1991. Recently reauthorized by Congress to the year 2019, current spending under CWPPRA constitutes less than 10% of the funding required to sustain coastal Louisiana as it exists today. A descriptive analysis of selected projects (n=109) was conducted to analyze the economic efficiency associated with various …

Laboratory And Field Measurements Of Bioturbation By Macrofauna In A Coastal Setting, Skyler Neylon Jan 2006

Laboratory And Field Measurements Of Bioturbation By Macrofauna In A Coastal Setting, Skyler Neylon

LSU Master's Theses

Two ophiuroid species, Hemipholis elongata and Ophiophragmus spp. were studied in laboratory microcosms to elucidate patterns of sediment mixing for key bioturbators in the Mississippi Sound, Mississippi. The effects of bioturbation on artificially stratified sediments in microcosms were traced via time-series digital x-radiography. Preliminary results indicate that for three population densities of the brittle stars (comparable to field densities), a steady state volumetric bioturbation rate of 1-2 cm3/d is reached within two months of introduction to a fresh system. The preservation quotient, q, a fractional measure of preserved primary fabric, reached a minimum of 0.5 during the 16-week experiment. Maximum …

Effects Of Terraces On Submerged Aquatic Vegetation In Shallow Marsh Ponds In Coastal Southwest Louisiana, Christopher Dean Cannaday Jan 2006

Effects Of Terraces On Submerged Aquatic Vegetation In Shallow Marsh Ponds In Coastal Southwest Louisiana, Christopher Dean Cannaday

LSU Master's Theses

The wetlands of coastal Louisiana are disappearing at a rate of 65 to 80 km2yr-1. Most of the loss is the conversion of emergent marsh to shallow marsh ponds. Terracing is one restoration technique that has been used frequently in recent years. Terraces are small intertidal ridges built in shallow marsh ponds to reduce wave action. It is assumed that this will slow erosion of adjacent emergent marsh and increase Submerged Aquatic Vegetation (SAV) production, a key habitat component for many marsh fauna. Yet both relevant previous studies failed to show that terraces increased SAV abundance. …

Biopolitics Or The Legislation Of Life: A Foucauldian Analysis, Marina Basu Jan 2006

Biopolitics Or The Legislation Of Life: A Foucauldian Analysis, Marina Basu

LSU Master's Theses

Michel Foucault uses the term biopolitics to highlight the focus on life that is at the center of contemporary politics. Biopower or biopolitics is the maximization of life through various regulatory apparatuses that monitor, modify, and control life processes. I elucidate and exemplify Foucault's framework in order to show how the medical discourse exercises a certain kind of power over bodies in the name of health. My argument is that through the mechanisms of biopower, the juridico-medical discourse simultaneously makes pregnancy into an object of study and the pregnant woman into a subject of power. With the help of a …

Quality Characterization Of Cholesterol-Free Mayonnaise-Type Spreads Containing Rice Bran Oil, Karen Melissa Garcia Jan 2006

Quality Characterization Of Cholesterol-Free Mayonnaise-Type Spreads Containing Rice Bran Oil, Karen Melissa Garcia

LSU Master's Theses

Traditional mayonnaise is manufactured with soybean oil (SBO) and egg-yolk containing ingredients. About 1/4 of American consumers have some forms of cardiovascular disease, accounting for >40% of all deaths in USA. Rice bran oil (RBO), a healthy lipid source, has cholesterol-lowering effects, and could be used to replace SBO in mayonnaise preparation. To take advantage of the health benefits associated with RBO, food products containing RBO need to be developed and characterized. Cholesterol-free mayonnaise-type spreads containing RBO were developed using a constrained mixture design. Two studies were performed to determine sensory attributes driving acceptance and purchase intent and to optimize …

Food Purchasing Behaviors, Dietary Energy Density, Perceived Health Status, And Perceived Nutrition Knowledge Of Female Food Stamp Recipients Living In Southeast Louisiana, Carrie Marie Elks

LSU Master's Theses

Purchase and consumption of energy-dense nutrient poor [EDNP] foods by low-income individuals contributes to the lower diet quality and increased risk of chronic disease (e.g. obesity, type 2 diabetes) in this population. Food purchasing behaviors, dietary energy density [ED], perceived health status, and perceived nutrition knowledge were assessed in 22 female food stamp recipients in Southeast Louisiana. Two 24-hour recalls (at the beginning and at the end of the month) and food expenditure receipts were collected; participants also completed several questionnaires. Fifty percent [%] (n=11) of study participants were food secure, and fifty percent (n=11) were food insecure. Sixty-four % …

Distribution And Biogeography Of Central American Howling Monkeys (Alouatta Pigra And A. Palliata), Amrei Baumgarten Jan 2006

Distribution And Biogeography Of Central American Howling Monkeys (Alouatta Pigra And A. Palliata), Amrei Baumgarten

LSU Master's Theses

Central America has two howling monkey species: the widespread mantled howling monkey (Alouatta palliata) and the endemic and endangered black howling monkey (A. pigra) limited to southeastern Mexico, northern Guatemala and Belize. Studies that verify the distribution of these species are needed, especially in their contact zones where sympatry is reported. Their evolutionary history remains controversial. My study examines their distribution at a local scale in a potential contact zone in eastern Guatemala through direct observations and interviews and at a regional scale across the entire isthmus using data from museum specimen localities, study sites, historic records and field surveys. …

The Body Politic: Splitting Gender Medically In Eighteenth-Century Philadelphia, Sarah Sally Carraher Jan 2006

The Body Politic: Splitting Gender Medically In Eighteenth-Century Philadelphia, Sarah Sally Carraher

LSU Master's Theses

Before the rise of clinical medicine, Western medicine was undergoing several prerequisite shifts in epistemology and methodology - moving from an eighteenth-century practice of spaces and classes, wherein the symptom is synonymous with the disease, toward a nineteenth-century science of signs and cases, in which symptoms are symbols, or products, of a deeper disease (Foucault 1973). During the former age of classes, about mid-century, a particular shift in the medical perception of sex differences appears in the literature, without any great advances or revisions in human anatomical knowledge or treatment methods. This thesis looks at hospitalization of in-patients at Pennsylvania …

Winter Diet, Seed Preferences And Foraging Behavior Of Henslow's Sparrows (Ammodramus Henslowii) In Southeastern Louisiana, Jennifer K. Dimiceli Jan 2006

Winter Diet, Seed Preferences And Foraging Behavior Of Henslow's Sparrows (Ammodramus Henslowii) In Southeastern Louisiana, Jennifer K. Dimiceli

LSU Master's Theses

Henslow's Sparrow (Ammodramus henslowii) is a grassland bird whose population is declining throughout its range, mainly due to habitat loss. The Longleaf Pine forest ecosystems in which Henslow's Sparrows spend their winters are reduced to 5% of their former range. The winter ecology of Henslow's Sparrow remains understudied, especially regarding important aspects of diet and foraging behavior. To determine winter diet, I collected fecal samples from Henslow's Sparrows during banding operations in southeastern Louisiana pine savannas from October 2003-March 2004 and October 2004-April 2005. I then analyzed the samples for presence of seeds and arthropod parts, identified them to the …

Effects Of Fire On Habitat Associations, Abundance, And Survival Of Wintering Henslow's Sparrows (Ammodramus Henslowii) In Southeastern Louisiana Longleaf Pine Savannas, Erik Ivan Johnson Jan 2006

Effects Of Fire On Habitat Associations, Abundance, And Survival Of Wintering Henslow's Sparrows (Ammodramus Henslowii) In Southeastern Louisiana Longleaf Pine Savannas, Erik Ivan Johnson

LSU Master's Theses

The Henslow’s Sparrow (Ammodramus henslowii) is the fastest declining short-distance migrant and fastest declining grassland bird in North America. Declines in longleaf pine (Pinus palustris) savannas, its primary wintering habitat, have exceeded 97%. Other than basic habitat requirements, very little is known about its wintering ecology. I examined habitat associations of wintering Henslow’s Sparrows resulting from fire in longleaf pine savannas in southeastern Louisiana during two winters. Because it is important to understand the relative importance of habitat parameters, which include structure, species composition, and food availability, I measured these to determine their relative importance to Henslow’s Sparrow densities. I …

The Discursive Practices Of Chemical Discipline, Roger L. Pippin Jan 2006

The Discursive Practices Of Chemical Discipline, Roger L. Pippin

LSU Master's Theses

This project examines the history of science and its relationship to the popular, or lay, audience, a problem of rhetorical inquiry since Aristotle. This project also explores the implications of the emerging trend in lay literature on Attention Deficit Hyperactivity Disorder (ADHD) to transform the causal mechanism underlying ADHD so that it is isomorphic in structure and parallel in content to the most contemporary and fetishized sciences of the human body. In other words, how ADHD was once a problem of brain chemistry, and is now a problem of genetics is not simply a matter of scientific practice on the …

Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger Jan 2006

Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger

LSU Master's Theses

The Southeastern United States has the most diverse and imperiled freshwater mussel (Unionidae) fauna in the world. The community structure and decline of these organisms is the result of complex interactions between biotic and abiotic factors, but the limited spatial scale of most community studies has failed to elucidate the underlying mechanisms shaping community structure. Basing community assessments solely on microhabitat variables alone has lead to stark contradictions in management recommendations and opposing definitions of habitat requirements for these organisms. However, with the introduction of GIS technology into aquatic management, it is now feasible to include variables from larger spatial …

Experimental And Computational Analysis Of Random Cylinder Packings With Applications, Wenli Zhang Jan 2006

Experimental And Computational Analysis Of Random Cylinder Packings With Applications, Wenli Zhang

LSU Doctoral Dissertations

Random cylinder packings are prevalent in chemical engineering applications and they can serve as prototype models of fibrous materials and/or other particulate materials. In this research, comprehensive studies on cylinder packings were carried out by computer simulations and by experiments. The computational studies made use of a collective rearrangement algorithm (based on a Monte Carlo technique) to generate different packing structures. 3D random packing limits were explored, and the packing structures were quantified by their positional ordering, orientational ordering, and the particle-particle contacts. Furthermore, the void space in the packings was expressed as a pore network, which retains topological and …

The Regulation Of Genes Involved In Trichome Development, Matthew Lloyd Brown Jan 2006

The Regulation Of Genes Involved In Trichome Development, Matthew Lloyd Brown

LSU Doctoral Dissertations

Arabidopsis thaliana is an organism that can be used as a model for most of the processes that occur in flowering plants. The leaf hairs, or trichomes, of Arabidopsis thaliana are macroscopic single cells that have been used as a model system for cell fate determination, cell expansion, cell cycle regulation, cell wall deposition, as well as other processes. Initiation of the trichome cell fate is controlled by a complex of genes including GLABRA1 (GL1), TRANSPARENT TESTA GLABRA (TTG), and GLABRA3 (GL3). This work examines the role of GL3 in trichome initiation and uses plants expressing varying levels of GL3 …

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li Jan 2006

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li

LSU Doctoral Dissertations

In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich literature in modeling methods, the sample size/power analysis methods for such mixed effects models are sparse. The sample size/power analysis method for the logistic-normal regression model is not readily available. This study is to develop a power analysis/sample size estimation method for the logistic-normal regression model. Extended from the sample size method for the likelihood …

Nutrient Constraints On Plant Community Production And Organic Matter Accumulation Of Subtropical Floating Marshes, Guerry O., Jr. Holm Jr. Jan 2006

Nutrient Constraints On Plant Community Production And Organic Matter Accumulation Of Subtropical Floating Marshes, Guerry O., Jr. Holm Jr.

LSU Doctoral Dissertations

In the cycle of delta growth and decay, peat-forming wetlands span a time and space continuum. Later in the delta cycle, freshwater floating marshes become increasingly removed from external sediment subsidy and internal nutrient cycling controls plant productivity and organic matter accumulation. An interesting question is whether increased external nutrient loading can affect the basic processes that lead to peat formation—plant production and organic matter decomposition. I conducted several field studies to understand whether belowground organic matter accumulation and decomposition were affected with increased nutrient exposure; in addition, the plant community was monitored over three years. A laboratory soil respiration …

Spectral Analysis Of Total Suspended Solids Mixtures For Solids Composition Determination, Curtis W. Sutherland Jan 2006

Spectral Analysis Of Total Suspended Solids Mixtures For Solids Composition Determination, Curtis W. Sutherland

LSU Doctoral Dissertations

Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of those solids are time-consuming and expensive. The research reported herein investigates the use of instrumental analysis using reflectance spectra of TSS as an attractive alternative to sufficiently characterize and identify TSS in a more rapid and economical method that could be used to study TSS transport and to identity TSS points of origin. For this investigative …

Stage(D) Mothers: Mother-Daughter Tropes In Twentieth-Century American Drama, Kristin Hanson Jan 2006

Stage(D) Mothers: Mother-Daughter Tropes In Twentieth-Century American Drama, Kristin Hanson

LSU Doctoral Dissertations

The relationship between mother and daughter is an important one for many women. In learning how to best become a successful member of society, daughters look to their mothers to demonstrate the behaviors and beliefs appropriate to a female. Such explicit and implicit instruction makes the mother-daughter relationship a central one in the socialization of women. Because it is such a powerful site, the mother-daughter relationship has received attention in the world of representation. Of particular import to this study is the representation of the mother-daughter relationship in Twentieth-Century American drama. Recent scholarship has shown that such representations can, however, …

Say It Loud! I'M Black And I'M Proud!: A Study Of Successful Black Female Students Educated In An Urban Middle School, Menthia P. Clark

LSU Doctoral Dissertations

"Acting White" (Fordham & Ogbu, 1986) is a common term among researchers who study academic achievement and racial identity among minority students which signifies the tension some academically successful minority students experience as they excel in school. Black students who contend with such tension may be teased, alienated, or rejected by their peers who view academic achievement as characteristic of White people. In order to avoid the accusation of "acting White," many Black students underachieve, conceal their academic talents, or make no efforts to pursue academic goals. For Black female high-achieving students, "acting White" is laden with gender-specific strategies of …
