A Genetic Bayesian Approach For Texture-Aided Urban Land-Use/Land-Cover Classification, Wenxue Ju Jan 2008

A Genetic Bayesian Approach For Texture-Aided Urban Land-Use/Land-Cover Classification, Wenxue Ju

LSU Doctoral Dissertations

Urban land-use/land-cover classification is entering a new era with the increased availability of high-resolution satellite imagery and new methods such as texture analysis and artificial intelligence classifiers. Recent research demonstrated exciting improvements of using fractal dimension, lacunarity, and Moran’s I in classification but the integration of these spatial metrics has seldom been investigated. Also, previous research focuses more on developing new classifiers than improving the robust, simple, and fast maximum likelihood classifier. The goal of this dissertation research is to develop a new approach that utilizes a texture vector (fractal dimension, lacunarity, and Moran’s I), combined with a new …

Richard Rorty's Map Of Political Misreading, Shaun Kenan King Jan 2008

Richard Rorty's Map Of Political Misreading, Shaun Kenan King

LSU Master's Theses

For more than a quarter century, Richard Rorty was one of the most controversial writers. Critics of Rorty have often clustered their remarks around distinct themes within Rorty’s body of literature. Is Rorty’s criticism of the correspondence theory of truth valid and what standard of validity could confirm that? Does Rorty’s treatment of pragmatists such as William James and John Dewey accurately reflect their writings? Is Rorty’s brand of liberalism defensible when it assumes no non-circular form of justification can be proffered? These are the questions most often addressed by Rorty’s critics. He responded to their objections for two decades. …

The Gallant Six Hundred: Performing The Light Brigade Into A Heroic Icon, Elizabeth Carrick Cawns Jan 2008

The Gallant Six Hundred: Performing The Light Brigade Into A Heroic Icon, Elizabeth Carrick Cawns

LSU Doctoral Dissertations

History is not so much what actually happened as how we have received and disseminated what happened. This reception and dissemination take place through a variety of media, many of which are not the purview of the traditional historian. It is in the trifles of daily life that we find the patterns of cultural norms – the ethos of the society that is as unnoticed by that society as the air it breathes. Society makes choices that affect the future based on what has been disseminated, rather than on the original event. This is especially true of such military disasters …

Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera Jan 2008

Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera

LSU Master's Theses

The concept of forest certification, a relatively recent development in forestry, is based on the use of market-based incentives to encourage sustainable forest management practices. Since the majority of forests in US South are privately owned, certifying forests owned by non-industrial private forest (NIPF) landowners is an important issue. From the demand perspective of certification, pressure from non-governmental environmental organizations and consumer awareness has prompted major wood products retailers to state preferences for certified wood products. In the US, wood product demand in the retail home centers sector is second only to the home building industry. In addition, home center …

Synthesis Of Disubstituted Amino Acids And Peptide Inhibitors Of Amyloid Beta Aggregation, Gregory Todd Mccandless Jan 2008

Synthesis Of Disubstituted Amino Acids And Peptide Inhibitors Of Amyloid Beta Aggregation, Gregory Todd Mccandless

LSU Master's Theses

The aggregation process of amyloid beta from monomeric peptide to oligomers and fibrils is believed to be connected with the neurological disorder Alzheimer’s disease. The focus of this research is the synthesis of alpha, alpha-disubstituted amino acids and peptide inhibitors of amyloid beta aggregation. The inhibitors are designed to interrupt (or alter) this process by binding to amyloid beta’s central hydrophobic core region (residues 17-20, Leucine-Valine- Phenylalanine-Phenylalanine). Target specificity is achieved via self recognition by basing the inhibitors on the sequence in this region. The inclusion of disubstituted amino acids in the sequence of the inhibitors will provide a blocking …

Ancient Greek And Ancient Hebrew Agrarianism: An Ecocritical Study Of Hesiod's Works And Days And The Book Of Proverbs, Ernest Nathan Manning Jan 2008

Ancient Greek And Ancient Hebrew Agrarianism: An Ecocritical Study Of Hesiod's Works And Days And The Book Of Proverbs, Ernest Nathan Manning

LSU Master's Theses

The subject of this thesis revolves around the “Western” view of nature and its social origins. The author advances the subject through a comparison of two ancient texts: Hesiod’s Works and Days and the Old Testament book of Proverbs. He concludes that the Western view of nature gestated in agricultural societies of small-farmers who saw themselves as being both part of and separate from the natural world. Their ability to control nature being limited, they saw civilization as fulfilling a limited agricultural role in the cosmos, as being different but part of and not controlling the whole. In the last …

Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao Jan 2008

Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao

LSU Doctoral Dissertations

Rice straw fiber can be considered as important potential reinforcing filler for thermoplastic composite because of its lignocellulosic characteristics. It is thus of practical significance to understand and predict the thermal decomposition process of rice straw fibers. A method proposed by Málek, Šesták, and co-workers was used to investigate and model thermal decomposition process of common natural fibers with detailed analysis on rice straw system. Assuming a global model occurring within the entire degradation of natural fibers with consideration of fiber as one pseudo-component, model can be used to describe both isothermal and non-isothermal degradation process of most selected fibers …

Redutive Dehalogenation Of Chlorinated Alkanes By Novel Bacteria At The Petroprocessor Of Louisiana Inc. Superfund Site, Jun Yan

LSU Doctoral Dissertations

A reductively dehalogenating enrichment culture was established using chloroalkane-contaminated groundwater from the PetroProcessors of Louisiana, Inc. (PPI) Superfund site. Two novel, strictly anaerobic bacterial strains, designated as BL-DC-8 and BL-DC-9, were isolated from the enrichment culture. These strains represent the first bacteria known to anaerobically dehalogenate 1,2,3-trichloropropane, the degradation pathway of which was determined. Both strains could be cultured in completely defined basal medium and were also able to dehalogenate a variety of other vicinally chlorinated alkanes including 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane, 1,2-dichloroethane, and 1,2-dichloropropane via dichloroelimination reactions.

Application Of The Hyman Model To Evaluate The Water And Salt Budgets In Three Mangrove Sites Along Shark River, Everglades, Cheng-Feng Tsai

LSU Master's Theses

Mangrove trees play an important role in the maintenance and sustainability of coastal wetlands due to their ability to adapt and survive in a wide range of saline and tidal conditions. Hydrologic processes (e.g., inundation frequency) and salinity are important regulators controlling the growth and productivity of mangrove forests. To quantify how changes in landscape-level hydrology will influence these regulators in mangrove forests, the hydrology model (HYMAN) was applied to three sites with distinct tidal forcings along the Shark River estuary in the Everglades National Park. HYMAN model uses mass balance equation to determine daily water and salt budgets as …

Evaluation Of Three Methods For Teaching Intraverbals To Children With Language Delays, Nicole Trosclair-Lasserre Jan 2008

Evaluation Of Three Methods For Teaching Intraverbals To Children With Language Delays, Nicole Trosclair-Lasserre

LSU Doctoral Dissertations

Direct instruction is often necessary to develop language or expand language use in individuals with language delays. Previous research has begun to identify certain training conditions that result in more efficient use of instructional time devoted to language development. Specifically, incorporating mands into the instructional arrangement, increasing the quality of reinforcement delivered for interspersed tasks, and including instructive feedback stimuli into the consequences of learning trials have all demonstrated more efficient learning of targeted language skills. The purpose of the current investigation was to compare three methods for teaching intraverbals (i.e., conversation skills) to individuals with deficits in this area. …

The Mise En Scène Of Rossini's Le Siège De Corinthe And The Conventions Of Staging At The Paris Opéra In The 1820s, Tina Huettenrauch

LSU Master's Theses

Shortly before 1800, the publication of livrets de mise en scène, short manuals including information regarding costumes, set designs, and blocking (i.e., the movement of characters on stage), became increasingly popular in France. While theater scholars (Gösta M. Bergman, Marvin Carlson, Hellmuth Christian Wolff) have recognized the value of these documents for the history of staging (and blocking in particular), musicologists have tended to focus on their impact on visual aspects and realization of drama. Those who have looked at staging (H. Robert Cohen, Rebecca S. Wilberg, M. Elizabeth C. Bartlet) have largely ignored the period prior to 1827, …

Comparative Roles Of Herpes Simplex Virus Type 1 (Hsv-1) Glycoproteins In Cytoplasmic Virion Egress, Hyuncheol Lee Jan 2008

Comparative Roles Of Herpes Simplex Virus Type 1 (Hsv-1) Glycoproteins In Cytoplasmic Virion Egress, Hyuncheol Lee

LSU Master's Theses

HSV-1 acquires its final envelope by budding into cytoplasmic vesicles thought to be derived from Trans-Golgi Network (TGN) membranes. This process is facilitated by interactions among the carboxyl termini of viral glycoproteins and tegument proteins. To investigate the relative importance of different viral glycoproteins in cytoplasmic virion morphogenesis, a set of recombinant viruses were constructed silencing expression of the glycoprotein E (ΔgE), the carboxyl terminus of glycoprotein D (gDΔcp), and the membrane protein UL20 (ΔUL20). In addition, recombinant viruses were constructed having the ΔgE+gDΔcp, and the ΔgE+ΔgM (glycoprotein M) deletions. These recombinant viruses were constructed using the double-red, site-directed mutagenesis …
