Elizabeth Bishop's Poetic Personae: The Dark And The Bright., Joan Louise Fields Jan 1996

Elizabeth Bishop's Poetic Personae: The Dark And The Bright., Joan Louise Fields

LSU Historical Dissertations and Theses

The intrigue of Elizabeth Bishop's poetic texts lies in the design of her sonic elements, vocalized by her dramatic personae as she directs her play of words. She manages a cohesion among her concept or content, the phonemic nature of her chosen words, and the rhythmic phrasing of her lines. Her poetic texts convey an enigmatic, yet natural, tonal quality that is produced by the juxtaposition of opposite strains or "strands" of voice--one shadowed, darker; the other light, brighter. These strands include the voice of a little girl as well as mature male and female speakers. Beneath, yet interwoven with …

A Hierarchical Approach To Equilibrium Cycle Nuclear Fuel Analysis., Jon Juneau Jan 1996

A Hierarchical Approach To Equilibrium Cycle Nuclear Fuel Analysis., Jon Juneau

LSU Historical Dissertations and Theses

This research involved developing an expert system that allows a nuclear fuel engineer to quickly provide answers to strategic nuclear fuel management questions, which are typically broad based. Current nuclear fuel analysis research concentrates on getting more accurate and precise answers at the expense of using large computer programs to get answers that are too specific to answer the broad based questions. The expert system brings together several artificial intelligence techniques to allow a nuclear fuel engineer to consider several scenarios in a general way in order to quickly answer the fuel management questions asked. The expert system is based …

Groundwater Flow With Heat And Solute Transport In Sedimentary Basins., Guichang Lin Jan 1996

Groundwater Flow With Heat And Solute Transport In Sedimentary Basins., Guichang Lin

LSU Historical Dissertations and Theses

Numerical experiments were undertaken to understand (1) heat and fluid transport in an uplifted foreland basin where fluid flow is driven by topographic gradient, and (2) effects of expulsion of geopressured fluids on the thermodynamic system in salt basins. Thermal evolution of an uplifted foreland basin is strongly affected by thermal buffering of basement rocks. Thermal buffering by basement rocks does not permit constant heat flow along the sediment-basement contact, in contrast to many previous numerical studies. Ignoring basement effects can result in serious errors in temperature prediction, such as a false transient thermal pulse in the discharge area. Carbonaceous …

"It Is Leviathan": Family, Feminism, And American Drama., Janet Vanderpool Haedicke Jan 1996

"It Is Leviathan": Family, Feminism, And American Drama., Janet Vanderpool Haedicke

LSU Historical Dissertations and Theses

American drama has ever occupied a stepchild position in scholarship, its denigration rooted in the lure of domestic realism for even the most resistant of our playwrights. Maligned as solipsistic and regressive, this "leviathan" of mainstream American theatre putatively upholds through its content the unity of the mythologized family and through its form the closure of classical realism. Yet the legacy of this leviathan is an epistemological subversion and a transformative impulse. Those very plays which apotheosize American domestic realism ironically undermine its foundation in psychological causality, narrative linearity, transparent language, unmediated consciousness, and unified meaning. Destabilizing that objective reality …

Poverty And Social Control In Early Modern England: Exeter, 1558-1625., Connie S. Evans Jan 1996

Poverty And Social Control In Early Modern England: Exeter, 1558-1625., Connie S. Evans

LSU Historical Dissertations and Theses

Poverty has always been, and continues to be, one of the most pressing social problems, and one to which a number of solutions have been proposed through the ages. The present work is an examination of the problem and the responses to it in early modern England, and is set in the local context of the city of Exeter. Prior to the reign of Elizabeth I, the majority of poor law legislation was punitive in nature. rather than rehabilitative. That the nature of poor law legislation changed under Elizabeth was due to a number of factors, not least of which …

American Literary Environmentalism, 1637-1872., David Mazel Jan 1996

American Literary Environmentalism, 1637-1872., David Mazel

LSU Historical Dissertations and Theses

The American environment is a mythic narrative that has served to mystify the social and economic relationships linking people and place. This study examines the early writing of the environment, from the 1637 Pequot War to the creation of the first national parks in the late nineteenth century. Chapter 1 draws on the work of Michel Foucault and Edward Said to theorize "literary environmentalism" as a knowledge-power formation that functions as a domestic Orientalism. Chapter 2 theorizes the narratological and psychosociological bases of environmental constructions generally before analyzing two colonial texts whose literary environmentalism is paradigmatic: John Underhill's Newes from …

School Social Climate And Individual Student Achievement In Rural High Schools., Leslie Faye Jones Jan 1996

School Social Climate And Individual Student Achievement In Rural High Schools., Leslie Faye Jones

LSU Historical Dissertations and Theses

This study examined the relationship of individual student achievement with four variables--school social climate, race, gender, and socioeconomic status. Each of these variables was expected to be significantly related to student achievement. Student achievement was measured by the LEAP sores (averages of mathematics, language arts, and writing components of the test). School social climate was measured by the Brookover (1969) school social climate questionnaire. Researchers have searched for years for an explanation of the differences in student achievement levels. The differences in student achievement levels were noted as early as the 1800's, and many studies have been done linking various …

The "Sacred Harp" In The Urban North: 1970-1995., Mark David Johnson Jan 1996

The "Sacred Harp" In The Urban North: 1970-1995., Mark David Johnson

LSU Historical Dissertations and Theses

In 1994 the Sacred Harp, a southern, shape-note tunebook, entered its 150th year of continuous use. First compiled in 1844 by B. F. White and E. J. King, and updated numerous times, The Sacred Harp books in the "Denson" tradition, including The Sacred Harp: 1991 Edition, are today the most popular and widely used twentieth-century revisions of any nineteenth-century tunebook. Sacred Harp singing has been a largely rural, Southern tradition and in the years between 1844 and the early 1970s several hundred separate singings were founded, many of which continue to be active. In the early 1990s the Sacred Harp …

Xanthomonas Albilineans Detection, Identification And Infectivity Titration In Sugarcane., Silvio Aparecido Lopes Jan 1996

Xanthomonas Albilineans Detection, Identification And Infectivity Titration In Sugarcane., Silvio Aparecido Lopes

LSU Historical Dissertations and Theses

A PCR method with primers for t-RNA gene spacers was used for detection of Xanthomonas albilineans (Xa), the causal agent of leaf scald disease of sugarcane. A DNA segment of approximately 170 bp was amplified for Xa strains, but also for X. campestris pv. campestris, X. campestris pv. translucens and two sugarcane bacterial endophytes. Good agreement between PCR and isolation to detect Xa from sugarcane sap was observed. PCR was faster allowing pathogen detection in less than one day. Both methods resulted in low detection frequencies from asymptomatic plants, which may contain Xa below detection limits. The lowest limit for …

Reflection On Teaching: An Ethnographic Study Of Preservice Teachers' Beliefs And Practices., Thomasine Haskins Mencer Jan 1996

Reflection On Teaching: An Ethnographic Study Of Preservice Teachers' Beliefs And Practices., Thomasine Haskins Mencer

LSU Historical Dissertations and Theses

The purpose of this study was to explore the relationship between preservice teachers' expressed beliefs, their practices, and how they described the two. Particular emphasis was given to factors that influenced the preservice teachers' expectations of students. The preservice teachers were in the graduate year of a five year teacher education program that embraced reflective practice. In many ways, the two preservice teachers conformed to the mold of the typical American teacher in that they were middle class, Anglo Saxon, females who were high achievers from small towns. However, the pair differed in their experiences with diversity. The preservice teachers' …

Neighborhood Characteristics And Crime Specific Victimization Rates: A Sociological Analysis., Esther Celeste Jones Jan 1996

Neighborhood Characteristics And Crime Specific Victimization Rates: A Sociological Analysis., Esther Celeste Jones

LSU Historical Dissertations and Theses

This dissertation examines the influence of ecological, institutional, and cultural variables on neighborhood victimization rates of assault, burglary, and robbery in 30 urban neighborhoods. Ordinary least square regression analysis is sued to determine which variables are most predictives of these rates. Based on social disorganization theory, social control theory, and subculture of violence theory, an integrated model is developed. The integrated model includes elements of all three theoretical orientations, clearly indicating that crime is not unidimensional, and that different variables are predictive of specific types of crime at the neighborhood level. It was found that assault and robbery were best …

Discontinuous Technological Change And Institutional Legitimacy: A Morphological Perspective., Robert Nicholas Mcgrath Jan 1996

Discontinuous Technological Change And Institutional Legitimacy: A Morphological Perspective., Robert Nicholas Mcgrath

LSU Historical Dissertations and Theses

Technological innovation is an important consideration to many strategic managers and thus is important to research in Strategic Management. Deepening the field's understanding of what technology is and how it works can be facilitated by participating in a growing dialogue between the Strategic Management and Management of Technology communities. This dissertation considers elements of both fields and examines the premise that at the industry level, incumbents act to manipulate the "share of mind" or "cognitive legitimacy" of the performance and cost/price characteristics of product-technology innovations that, in aggregate, portend to either enhance or destroy prevailing industry competences. A forecasting technique …

Experimental Lymphatic Filariasis In Gerbils (Meriones Unguiculatus): Molecular Cloning And Expression Of Gerbil Cytokines And Measurement Of Cytokine Gene Expression During A Primary Infection Of Brugia Pahangi., Zhiming Mai Jan 1996

Experimental Lymphatic Filariasis In Gerbils (Meriones Unguiculatus): Molecular Cloning And Expression Of Gerbil Cytokines And Measurement Of Cytokine Gene Expression During A Primary Infection Of Brugia Pahangi., Zhiming Mai

LSU Historical Dissertations and Theses

Cytokines play an important role in regulation of T cell responses. Two T helper cell subsets have been identified in some species and are defined by their cytokine secretion profiles. Th1 cells produce IL-2 and IFN-$\gamma,$ whereas Th2 cells express IL-4, IL-5, and IL-10. Precursor T cells that express a mixture of these cytokines are considered Th0 cells. It is hypothesized that primary infections of Brugia pahangi in gerbils induce an initial Th0 or Th1 like response which with time becomes a Th2 like response. To test this dynamic parasitism induced shift in cytokine profile, it is necessary to measure …

Variability Of Eddy Heat Fluxes Over The Northwestern Gulf Of Mexico., Varis Ransibrahmanakul Jan 1996

Variability Of Eddy Heat Fluxes Over The Northwestern Gulf Of Mexico., Varis Ransibrahmanakul

LSU Historical Dissertations and Theses

Eddy heat flux variability over the Louisiana-Texas shelf was investigated using satellite-derived surface velocity and temperature data between October 1993 and October 1994. Assuming the product of sea water density and specific heat is relatively constant, velocity-temperature covariance reflects eddy heat flux (the fluctuating part of the 1 x 1 degree, 90 day mean heat flux). Available velocity and temperature fields, however, are not synchronous. Temperature "observations" at velocity positions were optimally estimated using the Gauss Markoff Theorem. The error-estimate is comparable to the error resulting from the application of the widely accepted SST correction algorithm. The trend that instantaneous …

Breeding Ecology Of Songbirds In Bottomland Hardwood Forests Of Louisiana., Keith Ouchley Jan 1996

Breeding Ecology Of Songbirds In Bottomland Hardwood Forests Of Louisiana., Keith Ouchley

LSU Historical Dissertations and Theses

I examined productivity, survivorship and nest-site habitat characteristics of small terrestrial landbirds breeding in bottomland hardwood forest study sites in Louisiana. Bottomland hardwood forests are the dominate ecosystem of riverine floodplains in the southeastern United States, and these forests support a diverse bird community. Over 80 percent of this forest type has been lost, primarily due to agricultural clearing, and the relative abundance of many bird species that breed in these forests has also declined. The outcomes of 790 nests of 33 species were determined. For most species, productivity was greater in large forest tracts than in small tracts. Predation …

Le Temps Dans Les Oeuvres De Jorge Luis Borges, Edouard Glissant Et Saint-John Perse., Valerie Irene Loichot Jan 1996

Le Temps Dans Les Oeuvres De Jorge Luis Borges, Edouard Glissant Et Saint-John Perse., Valerie Irene Loichot

LSU Historical Dissertations and Theses

This dissertation compares conceptions of time as they appear in the works of Jorge Luis Borges, Edouard Glissant and Saint-John Perse. It attempts to stage a series of encounters among these writers, encounters or "relatings" in the sense of correlation and narration. The first relation is that expressed by Paul Ricoeur, who states that time becomes human only when it is articulated in narration and narration becomes human only when it describes the features of temporal experience. The second relation, or set of relations, occurs in the plural, interrupted, yet interconnected topos of the Americas. Through an analysis of the …

Inflammatory Responses Of The Jird To Brugia Pahangi: Parasite Stage Specificity And Role Of The Macrophage., Carmen Nasarre Jan 1996

Inflammatory Responses Of The Jird To Brugia Pahangi: Parasite Stage Specificity And Role Of The Macrophage., Carmen Nasarre

LSU Historical Dissertations and Theses

The host systemic and peritoneal inflammatory responses against different stages of Brugia pahangi were compared in intraperitoneally infected-jirds. Systemic inflammatory responses were assessed by measuring the pulmonary granulomatous response to B. pahangi antigen-coated beads (PGRN). Peritoneal inflammation was characterized by enumeration of different cell types in peritoneal exudates following infection. Further, the toxoplasmacidal activity and TNF-$\alpha$-like production of peritoneal macrophages were also characterized. Infection with L3, L4, male worms, female worms, microfilariae (MF) or dead adult worms induced a rapid PGRN. This response decreased to levels of controls in jirds inoculated with living parasites at the chronic time period, indicating …

Micellar Electrokinetic Remediation Of Tnt From Soil., Mohd Raihan Taha

LSU Historical Dissertations and Theses

An assessment of the feasibility of micellar electrokinetic (EK) remediation of TNT from soils is presented. Batch solubilization tests and bench scale EK tests were conducted to select the best candidate surfactant and to evaluate the efficiency of removal of TNT from a real world soil. From batch tests, it was found that SDS gave the best desorption results among a group of candidate surfactants, which includes DOWFAX 8390 (anionic), Tween 80 and Brij 35 (nonionic) and CTAB and CTAC (cationic). Unenhanced and surfactant enhanced EK tests was unable to move substantial amounts of TNT across the specimen to the …

A School For Utopia: Marietta Johnson And The Organic Idea., Janet Ruie Mcgrath Jan 1996

A School For Utopia: Marietta Johnson And The Organic Idea., Janet Ruie Mcgrath

LSU Historical Dissertations and Theses

This history, written from a feminist perspective, uses historical materials which trace unusual social and educational experiments in Fairhope, Alabama, in the early twentieth century. The early development of the utopian Fairhope community, founded by E. B. Gaston and a group of like-minded midwestern social reformers, is reviewed. Gaston's resolve to alleviate the worst inequities of monopolistic capitalism through practicing the single tax principles of Henry George is placed in historical context. Both the social experiment and its ideologically complementary Organic School are situated within the period known as the progressive era which followed closely upon the industrial revolution. The …

Biological Control Of Pythiaceous Fungi Causing Death Of Longleaf Pine Seedlings During Cold Storage., Xiaoan Sun Jan 1996

Biological Control Of Pythiaceous Fungi Causing Death Of Longleaf Pine Seedlings During Cold Storage., Xiaoan Sun

LSU Historical Dissertations and Theses

Pythium dimorphum Hendrix & Campbell and other Pythium species were determined to be pathogenic fungi that cause the death of longleaf pine seedlings during cold storage. Pathogenicity of these Pythium isolates as determined by infecting newly-germinated slash pine seedlings in vitro was confirmed in field evaluations. An in vitro dual culture screening system was effectively used for selecting Trichoderma isolates capable of killing P. dimorphum. Selected Trichoderma isolates and Gliocladium virens produced volatile and/or non-volatile antibiotics on solid media and in liquid cultures, but antibiotic production could be affected by medium type, pH, and culture age, depending on species or …

Teacher Preferences For And Actual Use Of Service Delivery Options: A Study Of Possible Influential Variables., Angela Michelle Waguespack

LSU Historical Dissertations and Theses

Variables influencing teacher preference for and actual use of two service delivery options, consultation and referral for evaluation, have previously been studied in isolation using varying methodologies. In this study, several variables including teacher attributions, organizational characteristics, child characteristics, and classroom behavior were studied in a comprehensive format. The relationship between these variables and teacher outcome expectancies, preference for services, and use of consultation versus referral was investigated. Sixty-seven teachers (grades K-8) seeking assistance for a student with behavior problems participated in the study. Teachers completed a demographic questionnaire, and measures of attributions, perceptions of problems, outcome expectancies, and preference …

The Generalized Kompaneets Equation., Kunyang Wang Jan 1996

The Generalized Kompaneets Equation., Kunyang Wang

LSU Historical Dissertations and Theses

In the dissertation, the generalized Kompaneets equation$${\partial u\over\partial t}={1\over\beta(x)}\lbrack\alpha(x)(u\sb{x}+ku+F(x,u))\rbrack\sb{x}$$(for $x,t>0)$ is studied. For the linear case, when $F\equiv0,$ a complete theory is given. A brief discussion is carried for the nonlinear case when $F(x,u)=f(x)g(u).$. For the following equation,$$v\sb{t}=\varphi(y,v\sb{y})v\sb{yy}+\psi(y,v,v\sb{y}),$$Goldstein and Lin's result is extended to degenerate case. Also, for the following linear operator,$$Au=\alpha(x)u\prime\prime+\beta(x)u\prime$$(for $x\in \lbrack 0,$ 1)), Clement and Timmermans' result is extended to the case of discontinuous coefficients $\alpha$ and $\beta$.

Image Analysis Quantification Of Decondensation Of Bovine Spermatozoa And Pcr Amplification Of A Y Chromosome Specific Sequence., Hilde Christina Steinholt Jan 1996

Image Analysis Quantification Of Decondensation Of Bovine Spermatozoa And Pcr Amplification Of A Y Chromosome Specific Sequence., Hilde Christina Steinholt

LSU Historical Dissertations and Theses

The first objective of this research was to develop a decondensation treatment for bovine spermatozoal DNA that worked consistently across bulls and breeds. The second objective was to use the decondensed DNA for polymerase chain reaction analysis of levels of Y-bearing spermatozoa in different ejaculates and in sex sorted spermatozoa. Decondensation of spermatozoa with dithiothreitol and potassium hydroxide was compatible with in vitro amplification and did not inhibit amplification. The polymerase chain reaction and image analysis were used to differentiate between proportions of Y spermatozoa by measuring fluorescent intensities of electrophoresed, polymerase chain reaction-amplified DNA. There were differences in intensities …

Modeling Physical And Chemical Nonequilibrium Transport Of Herbicide In Soils From Different Tillage Systems., Shikui Xue Jan 1996

Modeling Physical And Chemical Nonequilibrium Transport Of Herbicide In Soils From Different Tillage Systems., Shikui Xue

LSU Historical Dissertations and Theses

The physical and chemical nonequilibrium transport of alachlor were studied in a surface Gigger soil from different tillages through tracer studies, and batch and miscible displacement experiments. Batch experiments indicated initially fast reaction followed by slow adsorption. Adsorption and desorption results indicated time dependent hysteretic behavior and was best described by a multireaction model incorporating nonlinear equilibrium reaction, a reversible kinetic mechanism, and a consecutive irreversible mechanism. The model predicted alachlor hysteresis and adsorption-desorption kinetics satisfactorily based on parameters obtained from adsorption experiments. Tracer (Eosin Y and Blue FCF dyes) studies showed non-uniformly stained areas in undisturbed soil cores (6.4 …

Pilot-Scale Solvent Sublation For The Removal Of Hydrophobic Compounds From Wastewaters., Jeffrey Scott Smith Jan 1996

Pilot-Scale Solvent Sublation For The Removal Of Hydrophobic Compounds From Wastewaters., Jeffrey Scott Smith

LSU Historical Dissertations and Theses

Solvent sublation is a nonfoaming adsorptive bubble process which exploits the surface active nature of organic compounds in their removal from aqueous systems. Gas bubbles are introduced into an aqueous media and are buoyed upward to an immiscible organic solvent. As the bubbles rise, organic materials are selectively adsorbed from the aqueous phase and transported to the overlying, quiescent solvent layer. This dissertation studied three-phase, continuous solvent sublation of pyrene and pentachlorophenol from simulated wastewater at the pilot-scale. Steady-state removal efficiencies as high as 96% for pyrene and 94% for pentachlorophenol were demonstrated and were significantly greater than the corresponding …
