A Comparison Of A High-Resolution Survey And A Three-Dimensional Seismic Survey In A Feature-Rich Region Of The Green Canyon Area, Gulf Of Mexico, Bruce Miles Samuel Jan 2004

A Comparison Of A High-Resolution Survey And A Three-Dimensional Seismic Survey In A Feature-Rich Region Of The Green Canyon Area, Gulf Of Mexico, Bruce Miles Samuel

LSU Master's Theses

Recent advances in Autonomous Underwater Vehicle (AUV) technology have revolutionized the positioning and accuracy of high-resolution deep sea mapping tools. Geologic hazard and engineering surveys by AUV’s are producing high-resolution data sets of a quality that has never before been seen. Three-dimensional (3D) seismic data, though traditionally used for only deep subsurface mapping of large areas, is now being reprocessed at a higher resolution and utilized in well site investigations and geologic hazard assessments. This study makes a comparison between a 3D seismic survey and an AUV high-resolution survey in order to determine the strengths and weaknesses of both of …

The Portrayals Of Minority Characters In Entertaining Animated Children's Programs, Siobhan Elizabeth Smith Jan 2004

The Portrayals Of Minority Characters In Entertaining Animated Children's Programs, Siobhan Elizabeth Smith

LSU Master's Theses

The purpose of this study is to note, categorize, and discuss the stereotypes of African Americans in animated children’s cartoons. The purpose is also to compare them to see how they changed. A content analysis of two cartoons finds that characters do act in stereotypical ways. A quantitative analysis of 76 cartoons supports these findings. Overall, The Proud Family, a cartoon of the 21st century, is more stereotypical than Fat Albert and the Cosby Kids, a cartoon from 30 years ago. Though primary characters display the same amount of stereotypical behavior, secondary characters show an increase in the amount of …

The Influence Of Ethnic Embeddedness On The Gender Role Attitudes And Division Of Household Labor Of Married Hispanic Women, Susana Guerra Jan 2004

The Influence Of Ethnic Embeddedness On The Gender Role Attitudes And Division Of Household Labor Of Married Hispanic Women, Susana Guerra

LSU Doctoral Dissertations

In this study I examine the effects of both network structure and network function on the gender role attitudes and division of household labor among Hispanic women. Using a representative sub-sample drawn from the first wave of the National Study of Families and Households, I determine to what extent network processes help explain the gender role attitudes and behaviors of Hispanic women. Specifically, I focus on how embeddedness within a Hispanic community, as well as a woman’s level of social support exchange with kin and non-kin help explain her current gender role attitudes and household labor allocation. I found that …

Development Of A Neural Network Approach For The Assessment Of The Performance Of Traffic Sign Retroreflectivity, Nagajyothi Swargam Jan 2004

Development Of A Neural Network Approach For The Assessment Of The Performance Of Traffic Sign Retroreflectivity, Nagajyothi Swargam

LSU Master's Theses

The goal of the research was to develop a new predictive tool for assessing the performance of traffic sign retroreflectivity and to compare the developed tool with the existing linear regression models. Retroreflectivity decreases as sign sheeting ages. Currently Louisiana Department of Transportation and Development (LADOTD) replace signs with low reflectivity based on driver complaints. This practice might have resulted in premature sign replacement (removal of signs with several years of in-service life still remaining) or in non-replacement of signs that are not in compliance with LADOTD minimum reflectivity standards. In this study, both neural network models and regression models …

Black Women Writing Black Mother Figures: Reading Black Motherhood In Their Eyes Were Watching God And Meridian, Alexis Durell Powe Jan 2004

Black Women Writing Black Mother Figures: Reading Black Motherhood In Their Eyes Were Watching God And Meridian, Alexis Durell Powe

LSU Master's Theses

This research explores connections between Zora Neale Hurston's Their Eyes Were Watching God and Alice Walker's Meridian, two important novels in the African American canon rarely studied in conjunction. I examine the novels' portrayals of Black mothers, comparing and contrasting Nanny Crawford and Mrs. Hill as central mother figures. I also examine Leafy Crawford, Meridian Hill, and other minor Black mother/women characters. Though Hurston's and Walker's presentations of Black mothers differ, both authors work toward dismantling traditional stereotypes of Black motherhood, particularly the Black superwoman stereotype, and, thereby, ultimately redefining Black womanhood. In defending this claim, I explore Hurston's …

The Topography Of Syntactic Islands, Danielle Rachel Alfandre Jan 2004

The Topography Of Syntactic Islands, Danielle Rachel Alfandre

LSU Master's Theses

The Adjunct Island Constraint proposed by Ross (1967) together with Chomsky’s Barriers (1986) are not sufficient to account for the ungrammaticality of wh-extraction out of adjunct clauses, nor do they address the instances of grammatical extraction out of such constructions. Extraction out of Adjunct Islands is now completely predictable using a combination of Chomsky’s Minimalist Program (1995) and Kehler’s Coherence Theory (2002). The combination of these two theories gives an account of both the grammatical and ungrammatical instances of wh- extraction out of adjuncts. The principles of the Minimalist Program together with evidence from Old English adverbial clauses determines the …

Electrodeposition Of Feconicu Quaternary System, Qiang Huang Jan 2004

Electrodeposition Of Feconicu Quaternary System, Qiang Huang

LSU Doctoral Dissertations

Electrodeposition is a cost-effective method to produce thin film materials, which have been used widely in the microelectronic industry, and is advantageous to fabricate metal deposits into recessed and curved areas. In this dissertation, FeCoNiCu quaternary alloy system was investigated, both experimentally and theoretically, for fabrication of multilayers, grating structures, and nanowires. Multilayer structures are composed of alternating ferromagnetic and nonmagnetic nanometric layers, and are of interest due to the giant magnetoresistance (GMR) property it possesses, a change in electric resistance in the presence of an external magnetic field. In addition, the compositional modulation, or the composition contrast, in multilayer …

The Importance Of Fluent Component Skills In Mathematical Comprehension, Chisato Komatsu Jan 2004

The Importance Of Fluent Component Skills In Mathematical Comprehension, Chisato Komatsu

LSU Master's Theses

The primary question to be addressed by the present study was whether fluency on component skills is important in the development of overall competency in mathematics. Reading fluency has served as an excellent predictor of one’s reading comprehension. However, few studies have investigated whether the fluency on component skills is essential in the development of overall competency in mathematics. In fact, there has been a push for instructional strategies to deemphasize the importance component skills. In the current study, 140 students in second- through fourth- grade classrooms from general education participated. Each student took three curriculum-based measurement probes (a single-skill …

The Gender Gap In Political Knowledge: A Comparison Of Political Knowledge Levels In The United States, Canada, And Great Britain, Emily Marie Guynan

LSU Master's Theses

Previous research indicates that there is a gender gap in political knowledge. I examine whether the gender gap exists in the United States and what the significant determining variables are aside from gender. I also examine whether the gender gap exists in other countries and whether the variables that are significant in the United States are significant in other countries. I examine political knowledge levels in the United States, Canada, and Great Britain. By utilizing crosstabulations and multiple regression models, I find that a gender gap does exist in the United States as well as in Canada and Great Britain. …

Processing, Microstructure And Mechanical Behavior Of Nanocomposite Multilayers, Zuqiang Qi Jan 2004

Processing, Microstructure And Mechanical Behavior Of Nanocomposite Multilayers, Zuqiang Qi

LSU Doctoral Dissertations

Nanoscale multilayer coatings have high potential for numerous engineering applications because they can exhibit enhanced properties due to nanoscale effects and combine different properties from individual components. At present, scale effects on the mechanical behavior of multilayers are not well understood. Three multilayer nanocomposite systems, namely Al/Al2O3, Ti/TiN, and Cr/a-C, have been synthesized by using a dual-gun e-beam physical vapor deposition, to investigate the effect of layer thickness, the nature of components and their microstructures on the mechanical behavior. The deposited Al and Ti nanolayers were found to have polycrystalline fcc and hcp structure, respectively, the Cr and TiN layers …

Herbivore Movement And Spatial Population Dynamics In A Heterogeneous Landscape, Kyle Jonathan Haynes Jan 2004

Herbivore Movement And Spatial Population Dynamics In A Heterogeneous Landscape, Kyle Jonathan Haynes

LSU Doctoral Dissertations

To date, few metapopulation studies have isolated the effects of the intervening matrix from other attributes of landscape structure (e.g., patch geography or quality) that might influence dispersal among patches. Furthermore, there has been little exploration of the mechanisms underlying effects of the matrix on the spatial ecology of species. In this dissertation, I examine how the movement and distribution of the planthopper Prokelisia crocea within and among host-plant patches (prairie cordgrass, Spartina pectinata) is affected by the composition of the matrix (the invasive grass smooth brome [Bromus inermis], native non-host grasses, or mudflat). First, using a mark-recapture study in …

Service Recovery And The Elusive Paradox: An Examination Of The Effects Of Magnitude Of Service Failure, Service Failure Responsiveness, Service Guarantee And Additional Recovery Effort On Service Recovery Comes, Anthony Hugh Kerr

LSU Doctoral Dissertations

Service failure and recovery remain critical issues for both academicians and marketing practitioners. Defined as a service provider’s response to a failed service, service recovery can mean the difference between a firm’s success and failure, for increasing customer retention and limiting customer defection are integral components of organizational growth and profitability. The purpose of this dissertation was two-fold: (1) to test the effects of magnitude of service failure, service failure responsiveness, and the presence of a service guarantee on customer satisfaction levels and other service recovery outcomes (Study 1); and (2) to test the effects of additional recovery effort and …

Bees Associated With Louisiana Longleaf Pine Savannas, Chanda Sara Bartholomew Jan 2004

Bees Associated With Louisiana Longleaf Pine Savannas, Chanda Sara Bartholomew

LSU Master's Theses

Longleaf pine savannas are perhaps the most threatened ecosystems in North America. Despite a well documented and highly diverse flora, little has been published on insects in general and, in particular, on bees that provide the valuable service of plant pollination. Thus, the aims of this study were to: 1) survey bees found in two savanna types in southeastern Louisiana; and 2) contrast the diversity and species composition of these two savanna types. An ancillary goal was to contrast two collecting protocols for bees in the savanna habitat. Overall, a total of 3,407 bees were collected representing 125 species. Of …

Paul Durand-Ruel And The Market For Early Modernism, Marci Regan Jan 2004

Paul Durand-Ruel And The Market For Early Modernism, Marci Regan

LSU Master's Theses

This thesis examines the art sales and marketing of Impressionism in the late nineteenth century, focusing on the dealer Paul Durand-Ruel. Throughout the nineteenth century in Paris, the Académie des Beaux-Arts wrote the history of art by supporting certain artists who followed its ideas of what art should look like. The artists that the Academy chose to support had lucrative careers; they were offered commissions from both the church and state to paint grand historical pictures. Throughout the nineteenth century and until World War II, Paris was the artistic center of the world, and the birthplace of many avant-garde groups. …

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier Jan 2004

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier

LSU Doctoral Dissertations

The late modern and postmodern theme of homecoming permeates the philosophy of Martin Heidegger, who grapples with the topic throughout the various phases of his lifelong meditation on Being. Heidegger continually gave thought to the relationship between Being and the place or site in which it becomes manifest, whether it is a system of references and manipulable entities (Being and Time), language (An Introduction to Metaphysics), or aesthetic works of art (“The Origin of the Work of Art”). Taking as its point of departure Heidegger’s persistent and dynamic search for home (Heimat), this study will examine the political implications of …

The Relationship Between Social Behavior And Mealtime Behavior Problems In Individuals With Severe And Profound Mental Retardation, David E. Kuhn Jan 2004

The Relationship Between Social Behavior And Mealtime Behavior Problems In Individuals With Severe And Profound Mental Retardation, David E. Kuhn

LSU Doctoral Dissertations

One of the defining features of mental retardation is a problem in adaptive functioning. An area of adaptive skills commonly deficient in this population is social functioning, often characterized as behaviors that provide individuals with the means to interact effectively and appropriately with others. Researchers in this area have generally focused on improving appropriate social behavior and/or decreasing behavioral excesses that interfere with social interactions. Few studies have examined the effects of improving social behavior on collateral behaviors. The current study examined the relationship between social behavior and feeding and mealtime problem behavior in individuals with mental retardation. Individuals across …

Development Of A Predictive Model For Student-Athlete Retention And Graduation At Louisiana State University, Mary Allyn Boudreaux Jan 2004

Development Of A Predictive Model For Student-Athlete Retention And Graduation At Louisiana State University, Mary Allyn Boudreaux

LSU Doctoral Dissertations

The National Collegiate Athletic Association through its member institutions has implemented academic standards governing initial athletic eligibility and has led reform initiatives tying the ability to compete athletically to student-athlete retention and graduation. Louisiana State University (LSU), like many Division I institutions, admitted its scholarship athletes using these initial eligibility standards as a minimum qualification for admission. However, as NCAA requirements have become less stringent, the admissions requirements at LSU have increased. Concerns about the retention and graduation of student-athletes and an increasing gap between the academic credentials of the student body and student-athletes led administrators to question the wisdom …

Modeling Longleaf Pine (Pinus Palustris Mill) Wood Properties Using Near Infrared Spectroscopy, Brian Kipling Via Jan 2004

Modeling Longleaf Pine (Pinus Palustris Mill) Wood Properties Using Near Infrared Spectroscopy, Brian Kipling Via

LSU Doctoral Dissertations

This research demonstrated model development for important wood properties using near infrared spectroscopy (NIR); it considered the effect of outside sources of error, and the ability of NIR to measure fiber morphology. Strength, stiffness, and density were successfully modeled from wood samples taken throughout 10 longleaf (Pinus palustris Mill) trees. Principal components and multiple linear regression were compared for performance in prediction of density, strength, and stiffness. I found both modeling techniques to yield similar prediction accuracies. However, I found that density could be estimated through Beer-Lambert’s law since the absorbance at all wavelengths increased with density. Also, 5 of …

Tissue Interactions With Lasers And Liquid Nitrogen: A Novel Cryopreservation Method, Deepak Kandra Jan 2004

Tissue Interactions With Lasers And Liquid Nitrogen: A Novel Cryopreservation Method, Deepak Kandra

LSU Master's Theses

The importance of the imposed cooling rate in cryopreserving native cells and tissues has been long recognized in the field of cryobiology. When biological tissues are subjected to cooling rates in excess of thousands of degree C per minute, the characteristic structural and physical manifestations of the ice formed are such that the traditional damage due to ice formation at lower cooling rates are suppressed. Hence, achieving high cooling rates in tissues and cells of biologically relevant sizes (mm’s and cm’s) has been a long standing research problem. In the present study, we present a novel technique to achieve high …

Detection And Mapping Of Quantitative Trait Loci That Determine Responsiveness, Janet L. Mueller, E. A. Ellenberger, Linda K. Vaughn, John K. Belknap, Raymond M. Quock

Biomedical Sciences Faculty Research and Publications

Exposure to 70% N2O evokes a robust antinociceptive effect in C57BL/6 (B6) but not in DBA/2 (D2) inbred mice. This study was conducted to identify quantitative trait loci (QTL) in the mouse genome that might determine responsiveness to N2O. Offspring from the F2 generation bred from B6 and D2 progenitors exhibited a broad range of responsiveness to N2O antinociception as determined by the acetic acid-induced abdominal constriction test. QTL analysis was then used to dissect this continuous trait distribution into component loci, and to map them to broad chromosomal regions. To this end, …

Interactive Regulation Of Dissolved Copper Toxicity By An Estuarine Microbial Community, Christina L. Dryden, Andrew S. Gordon, John R. Donat Jan 2004

Interactive Regulation Of Dissolved Copper Toxicity By An Estuarine Microbial Community, Christina L. Dryden, Andrew S. Gordon, John R. Donat

OES Faculty Publications

Cultured marine microorganisms under copper stress produce extracellular compounds having a high affinity for copper (copper-complexing ligands). These ligands are similar in binding strength to those found in natural waters, but few studies have examined the relationship between copper, copper-complexing ligand concentrations, and natural microbial populations. A series of in situ experiments in the Elizabeth River, Virginia, revealed that an intact estuarine microbial community responded to copper stress by production of extracellular, high-affinity copper-complexing ligands. The rate of ligand production was dependent on copper concentration and resulted in a reduction of the concentration of free cupric ions, Cu2+, …
