Evaluation Of Vetiver Oil And Alate Biology As Preventative Measures Against The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki (Isoptera: Rhinotermitidae), Karen Elizabeth Nix Jan 2005

Evaluation Of Vetiver Oil And Alate Biology As Preventative Measures Against The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki (Isoptera: Rhinotermitidae), Karen Elizabeth Nix

LSU Master's Theses

The Formosan subterranean termite, Coptotermes formosanus Shiraki, is responsible for over $1 billion in property damage, repairs, and control in the United States. Presently, control of this exotic pest depends mainly on chemical methods. There is an increasing interest in using natural products in pest control because of their low mammalian toxicity and environmental safety. Chemical components of the roots of vetiver grass, Vetiveria zizanioides (L.) Nash, have shown to be effective repellents and toxicants to Formosan subterranean termites. Objectives of this research were to evaluate: 1) vetiver grass root growth and its oil distribution; 2) vetiver oil, nootkatone, and …

Denitrification And Greenhouse Gas Emissions From Cultivated And Wetland Alluvial Soils, Sami Ullah Jan 2005

Denitrification And Greenhouse Gas Emissions From Cultivated And Wetland Alluvial Soils, Sami Ullah

LSU Doctoral Dissertations

Agricultural development in the Mississippi River Basin has contributed to an 3-fold increase in NO3 loading of the river. Increased NO3 loading is a primary cause of eutrophication in the northern Gulf of Mexico. Identification of best management practices (BMPs) to reduce NO3 loss and wetlands restoration to remove NO3 through denitrification are critically needed. The objectives of this research were to determine factors controlling denitrification potential of different landscape units in an agricultural watershed and quantify the effects of BMPs and organic C amendments on denitrification rates of cultivated lands and restored forested wetlands. N2O, CH4 and CO2 emissions …

Detection Of Biologically Important Molecules, Kyukwang Kim Jan 2005

Detection Of Biologically Important Molecules, Kyukwang Kim

LSU Doctoral Dissertations

Anions play important roles in biological systems. The design of anion sensors has been of great interest. The selective detection of a specific anion is particularly challenging. In the first chapter, I describe the synthesis of a TBS-protected fluorescein dye (1.1) and its use for the selective detection of fluoride. Solutions of 1.1 either in DCM or in aqueous media at physiological pH show the excellent selectivity towards fluoride to afford color formation while solutions of other interfering anions remain colorless. The monitoring of homocysteine (Hcy) and cysteine (Cys) levels is important since they are biomarkers associated with Alzheimer’s and …

Liquid Architectures: Marcos Novak's Territory Of Information, Camile A. Silva Jan 2005

Liquid Architectures: Marcos Novak's Territory Of Information, Camile A. Silva

LSU Master's Theses

The idea of interactivity between humans and their environment no longer represents the only way of exploring new experiences. Equally passé is the idea that information constitutes the means for this interaction. However, this paper presents that the contemporary idea for interaction has embraced new understandings of the content of experience and the structure of space. New electronic technologies and advanced digital media have separated realities from the realm of the body and transformed experiences into a ubiquitous event. The architectural discourse, that once has been largely a discourse of form and style, has finally overcome those limitations and has …

La Madame Et La Mademoiselle: Creole Women In Louisiana, 1718-1865, Katy Frances Morlas Jan 2005

La Madame Et La Mademoiselle: Creole Women In Louisiana, 1718-1865, Katy Frances Morlas

LSU Master's Theses

In Louisiana during the eighteenth and nineteenth centuries, a unique group of people known as Creole created a culture that differed from the rest of the United States. Descendants of the first French and Spanish settlers, Creoles both black and white struggled to maintain their heritage despite an influx of Anglo-American Protestants into Louisiana; women in particular sought to preserve their culture. Although black Creole women have received significant attention, their white counterparts remain virtually absent in scholarship. This thesis focuses on the lives of white Creole women in the River Parishes and New Orleans and seeks to recreate the …

The Free World Confronted: The Problem Of Slavery And Progress In American Foreign Relations, 1833-1844, Steven Heath Mitton Jan 2005

The Free World Confronted: The Problem Of Slavery And Progress In American Foreign Relations, 1833-1844, Steven Heath Mitton

LSU Doctoral Dissertations

Enacted in 1833, Great Britain’s abolition of West Indian slavery confronted the United States with the complex interrelationship between slavery and progress. Dubbed the Great Experiment, British abolition held the possibility of demonstrating free labor more profitable than slavery. Besides elating the world’s abolitionists, always hopeful of equating material with moral progress, the experiment’s success would benefit Britain economically. Presented evidence of the greater profits of free labor, slaveholders worldwide would find themselves with compelling reason to abandon slavery. Likewise, London policymakers would proceed with little need—and no economic incentive—to promote abolition in British foreign policy. British hopes foundered on …

The Evolution Of Prezygotic Reproductive Isolation In The Drosophila Pseudoobscura Subgroup, Sheri Dixon Schully Jan 2005

The Evolution Of Prezygotic Reproductive Isolation In The Drosophila Pseudoobscura Subgroup, Sheri Dixon Schully

LSU Doctoral Dissertations

Newly forming species that have differentiated in allopatry may evolve numerous barriers that prevent the interbreeding when they come back into contact with each other. The objective of this dissertation is to evaluate some mechanisms of prezygotic reproductive isolation in the D. pseudoobscura subgroup. I begin by evaluating how the evolution of female preferences and male sexual characters lead to reinforcement between Drosophila pseudoobscura and its congener D. persimils. In particular, I will evaluate two alternative hypotheses; Preference Evolution and Discrimination Enhancement, to determine how selection reduces hybridization between these sister species. Both hypotheses predict a reduction in the overlap …

Tonality And Drama In Verdi's "La Traviata", David Bradley Easley Jan 2005

Tonality And Drama In Verdi's "La Traviata", David Bradley Easley

LSU Master's Theses

Scholars hold opposing views concerning the importance of large-scale key relations in Verdi's operas. Julian Budden states that, since Verdi often allowed transpositions of his music in performance, one must take care in assigning structural importance to Verdi's key schemes. Others, including David Lawton, place much significance on Verdi's choice of keys. Lawton describes methods by which Verdi intensifies dramatic situations through associative tonality and recurring musical themes. In La Traviata, several recurring musical themes undergo transposition, a device that Wagner scholar Robert Bailey calls expressive tonality, which is the repetition or recall of a passage transposed by semitone …

Civil War Prisons In American Memory, Benjamin Gregory Cloyd Jan 2005

Civil War Prisons In American Memory, Benjamin Gregory Cloyd

LSU Doctoral Dissertations

The memory of Civil War prisons has always been contested. Since 1861, generations of Americans struggled with the questions raised by the deaths of approximately 56,000 prisoners of war, almost one-tenth of all Civil War fatalities. During the war, throughout Reconstruction, and well into the twentieth century, a sectional debate raged over the responsibility for the prison casualties. Republican politicians invoked the savage cruelty of Confederate prisons as they waved the bloody shirt, while hundreds of former prisoners published narratives that blamed various prison officials and promoted sectional bitterness. The animosity reflected a need to identify individuals responsible for the …

Reciprocal Peer Tutoring And Treatment Integrity Of Elementary School Students, Brian M. Esteve Jan 2005

Reciprocal Peer Tutoring And Treatment Integrity Of Elementary School Students, Brian M. Esteve

LSU Master's Theses

Academic concerns are the most common reason students are referred for special services in schools. This obviously leads to the necessity for schools to have secondary prevention services in place to address the needs of students who are struggling. Peer tutoring, in its various forms, has been well documented as an effective and inexpensive intervention for all academic areas. Despite the promise of peer tutoring, research evidence suggests that teachers may not consistently carry out their roles in the peer tutoring process with sufficient accuracy to ensure positive outcomes. One possible solution to this problem is to have a consultant …

Mapping The Other Truth In The Shintech Case: Emancipatory Mapping For Environmental Justice In South Louisiana, Charles Allen Flanagan Jan 2005

Mapping The Other Truth In The Shintech Case: Emancipatory Mapping For Environmental Justice In South Louisiana, Charles Allen Flanagan

LSU Doctoral Dissertations

This dissertation presents an alternative mapping approach which challenges the hegemony of abstract space and instrumental reason propagated by the U.S. Environmental Protection Agency (EPA) in its 1998 study of the Louisiana Department of Environmental Quality's (DEQ) permitting process. The "other truth" is presented through application of concepts from critical theory, critical geography, and the works of Henri Lefebvre to a specific environmental justice struggle in St. James Parish, Louisiana. In 1996 Shintech, Inc. proposed building a polyvinyl chloride facility in St. James Parish, Louisiana. The community, concerned about the considerable toxic burden already present in the area, formed a …

Oxygen Uptake Efficiency Slope And Functional Physical Performance In Elderly Adults, Scott Eric Fuller Jan 2005

Oxygen Uptake Efficiency Slope And Functional Physical Performance In Elderly Adults, Scott Eric Fuller

LSU Master's Theses

Background: The Oxygen Uptake Efficiency Slope (OUES) attained during submaximal treadmill exercise is a reliable index of cardiorespiratory capacity in older adults. This investigation compares OUES values derived during treadmill walking and performance of the Continuous Scale Physical Function Performance test (CS-PFP). Method: A Cosmed portable metabolic cart was used to collect breath gases in 36 older adults (age: 81.8 +/- 7.8 years). Twenty-one subjects performed both the incremental treadmill test and the CS-PFP while an additional 15 subjects performed the CS-PFP, only. Results: The regression of log Ventilation vs. VO2 reveals similar correlations for the CS-PFP and treadmill …

Ceo Succession Processes And Agency Costs, Zeynep Ayca Altintig Jan 2005

Ceo Succession Processes And Agency Costs, Zeynep Ayca Altintig

LSU Doctoral Dissertations

In the 'passing the baton' succession process, the incumbent CEO/Chairman relinquishes the CEO title, but retains the Chairman title to facilitate monitoring the new CEO during a probationary period. The new CEO eventually wins the Chairman title if he is successful during the probationary period. We argue that this type of succession process can lead to managerial conformism and conservatism because reputation concerns give the retiring CEO incentives to pressure the new CEO to continue existing policies and to avoid making major changes that could substantially improve performance or increase firm value. Consistent with this hypothesis, we find no changes …

Cognitive Adaptation's Implication On Diabetic Adherence, Martin Ancona Jan 2005

Cognitive Adaptation's Implication On Diabetic Adherence, Martin Ancona

LSU Master's Theses

Diabetes, affecting more than 18 million people in the United States, is an epidemic problem. The illness is usually progressive, leading to neuropathy, blindness, and limb amputation. The most common type of the illness, Type 2 diabetes, is usually controllable through a strict combination of diet, exercise, and medication. However, non-compliance, rather than compliance, to prescribed diabetes regimens is the norm. Although past research has uncovered many of the reason that diabetics may fail to adhere to their regimen, the whole puzzle has not yet been solved. This study looked at the Cognitive Adaptation Theory in relation to diabetic adherence. …

Electrodeposition Of Magnetic Nanowires And Nanotubes, Despina Mehedintu Davis Jan 2005

Electrodeposition Of Magnetic Nanowires And Nanotubes, Despina Mehedintu Davis

LSU Master's Theses

The current perpendicular to the plane giant magneto-resistance (CPP)-(GMR) effect makes multilayered nanowires of huge interest as magnetic sensor materials. GMR showing multilayer nanostructures are composed of alternating ferromagnetic and nonmagnetic nanometric layers. The giant magnetoresistance (GMR) property is described as a change in electrical resistance when an external magnetic field is introduced. Electrodeposition is the most efficient method for fabricating magnetic nanowires. In addition to the cost-effectiveness, electrodeposition is one of the few methods that can overcome the geometrical restrictions of inserting metals into very deep nanometric recesses, making it the favored method for nanowire and nanotube fabrication. In …

Assessment Of Water Conservation Technique In Rice Culture To Develop Water Use Policies, Manoch Kongchum Jan 2005

Assessment Of Water Conservation Technique In Rice Culture To Develop Water Use Policies, Manoch Kongchum

LSU Master's Theses

The rapid growth of world population has resulted in significantly increased global water demand. According to a recent report on limited water supply, conservation techniques and water use policies are needed to preserve water resources. Worldwide agriculture is the largest consumer of water, particularly for growing rice. Water use for rice production was chosen because rice will continue to be a staple crop for the majority of the world’s population and because of its pervasive use of water. Hence, this thesis was designed to investigate water conservation possibilities for rice production in two water management regimes: alternate flooding and drying, …

The Abolition Of Wealth Transfer Taxes: Lessons From Canada, Australia And New Zealand, David G. Duff Jan 2005

The Abolition Of Wealth Transfer Taxes: Lessons From Canada, Australia And New Zealand, David G. Duff

All Faculty Publications

When the United States acted to phase-out its estate tax by 2010, it joined a small but growing group of countries which have also repealed their wealth transfer taxes. In Canada, federal gift and estate taxes were repealed in 1972 and provincial wealth transfer taxes were abolished in the 1970s and 1980s. In Australia, State and Commonwealth wealth transfer taxes were repealed in the late 1970s and early 1980s. New Zealand followed suit in the 1990s, reducing estate tax rates to zero in 1992 and repealing the tax in 1999. This paper reviews the abolition of wealth transfer taxes in …

Effects Of Gender Role On The Judgment Of Masculine Signs, Joseph C. Mitchell Jan 2005

Effects Of Gender Role On The Judgment Of Masculine Signs, Joseph C. Mitchell

LSU Doctoral Dissertations

Masculinity is a multi-dimensional, fairly pliable construct that some scholars approach from a biological perspective, others approach from a social constructionist perspective, and others approach from a unifying perspective. Part of the environment that informs the meaning of masculinity to a given culture is the mass media. This study takes the constructivist theoretical perspective, which attempts to explain the activation of schemata. The schematic process for this study concerns how people perceive, process, and judge masculine signs. This study seeks to explain gender role orientation’s influences on the development of schemata for masculinity as evidenced by differences in assessments of …

Three Views Of Anomaly And Their Heuristic Utility, Robert Rose Jan 2005

Three Views Of Anomaly And Their Heuristic Utility, Robert Rose

LSU Master's Theses

This thesis presents three views of anomaly in explanation: the linguistic view, the perceptual view, and the mechanistic view. The linguistic view is based on the notion that an anomaly is an instance of logical inconsistency. According to the perceptual view, an anomaly is a perceptual event which consists of a phenomenon deviating from a paradigmatic set of expectations. Lastly, the mechanistic view defines anomaly as a phenomenon which reveals the predictive failure of a model of the mechanism underlying the phenomenon to be explained. Each view is evaluated in terms of its heuristic utility, in two ways: first, according …

By The Numbers: The Region Votes Its Fate, Richard A. Clucas, Alton Straub Jan 2005

By The Numbers: The Region Votes Its Fate, Richard A. Clucas, Alton Straub

Institute of Metropolitan Studies Publications

The author examined how the residents in the five-county region of the metropolitan area (Clackamas, Columbia, Multnomah, Washington, and Yamhill) voted in the 2004 general election on selected ballot measures in order to understand the political values of the neighborhoods in which we live. Using geographic information systems (GIS), we mapped the distribution of votes by election precinct on what we thought were three of the most revealing measures: the constitutional amendment banning same-sex marriages (Measure 36), the initiative requiring state and local governments to pay landowners when land-use restrictions reduce property value (Measure 37), and the constitutional amendment limiting …

Incompressible Finite Elements Via Hybridization. Part Ii: The Stokes System In Three Space Dimensions, Bernardo Cockburn, Jay Gopalakrishnan Jan 2005

Incompressible Finite Elements Via Hybridization. Part Ii: The Stokes System In Three Space Dimensions, Bernardo Cockburn, Jay Gopalakrishnan

Mathematics and Statistics Faculty Publications and Presentations

We introduce a method that gives exactly incompressible velocity approximations to Stokes ow in three space dimensions. The method is designed by extending the ideas in Part I (http://archives.pdx.edu/ds/psu/10914) of this series, where the Stokes system in two space dimensions was considered. Thus we hybridize a vorticity-velocity formulation to obtain a new mixed method coupling approximations of tangential velocity and pressure on mesh faces. Once this relatively small tangential velocity-pressure system is solved, it is possible to recover a globally divergence-free numerical approximation of the fluid velocity, an approximation of the vorticity whose tangential component is continuous across …
