Electron-Pair Analysis For Doubly Excited Ridge States, Lijun Zhang, A. R.P. Rau Jan 1992

Electron-Pair Analysis For Doubly Excited Ridge States, Lijun Zhang, A. R.P. Rau

Faculty Publications

The two-electron Schrödinger equation is analyzed in hyperspherical coordinates, with the electrons described throughout as a pair. In contrast to the current adiabatic hyperspherical method, which reverts at large distances to a description in terms of individual electrons, the pair aspect is preserved also asymptotically. Whereas the adiabatic potential wells converge to single-ionization limits, we develop potential wells converging to the double-ionization limit of the system, and doubly excited states are then viewed as eigenstates of the pair in these wells. At the simplest level, we get series converging to the double-ionization limit which are described analytically by the pair-Rydberg …

A Study On Low-Frequency Variability In Current And Sea Level In The Lombok Strait And Adjacent Region., Dharma Arief Jan 1992

A Study On Low-Frequency Variability In Current And Sea Level In The Lombok Strait And Adjacent Region., Dharma Arief

LSU Historical Dissertations and Theses

Current meter data in the mid-Lombok Strait region in 1985 show that 42% of the variance in the currents is within the intraseasonal frequency band (10-100 day-1). It is about two times the variance of the tidal currents. This intraseasonal variability appeared as episodic northward flows of 20 to 80 cm/s recurring every 20 to 60 days. Our data indicate these northward flows are driven by episodes of sea-level rise south of the Lombok Strait which are controlled by large scale westerly wind events in the Southeastern Indian Ocean. These northward flow events occur almost simultaneously with either a cyclone …

Modeling Three-Dimensional Groundwater Flow And Solute Transport By The Finite Element Method With Parameter Estimation., Fang Xin Yu Jan 1992

Modeling Three-Dimensional Groundwater Flow And Solute Transport By The Finite Element Method With Parameter Estimation., Fang Xin Yu

LSU Historical Dissertations and Theses

A general, systematic and improved numerical formulation for the three-dimensional (3-D) groundwater flow and solute transport problems was derived, using the finite element method. In the numerical formulation, a hidden mistake, which has appeared in many textbooks and journal papers dealing with the advective term of the general 3-D solute transport equation, was found and corrected. Some simpler and practical expressions for the leaky boundary condition, surface flux condition, and sources and sinks were proposed. To improve the conventional formulation for the time derivatives, a combination of the Galerkin method and the collocation method was developed. A more accurate scheme …

The Keepers And The Kept: The First Hundred Years Of The Tennessee State Prison System, 1830-1930. (Volumes I And Ii)., Larry D. Gossett Jan 1992

The Keepers And The Kept: The First Hundred Years Of The Tennessee State Prison System, 1830-1930. (Volumes I And Ii)., Larry D. Gossett

LSU Historical Dissertations and Theses

Tennessee built its first state penitentiary in Nashville in 1830 on Sixteenth and Church Streets on land that is now a downtown parking lot. Revisions in the criminal code made many offenses punishable by imprisonment instead of corporal or capital punishment, and the convict population grew steadily. Continuing concern was expressed by the General Assembly that the penitentiary be self-supporting, and much effort was expended at all levels of government to accomplish that end. This study covers the history of approximately the first one hundred years of the Tennessee State Prison System. It begins with an overview of the criminal …

Improvement Of The Data Analysis Algorithm By Applying The Decision Tree Method., Won Chan Jung Jan 1992

Improvement Of The Data Analysis Algorithm By Applying The Decision Tree Method., Won Chan Jung

LSU Historical Dissertations and Theses

Data analysis (reconstructability analysis) is an area used on a data set which has several variables and a function value to find the most important factor that causes the function values to fall within a desired range. Normal data analysis algorithm (1) finds the most important factor in O (2$\sp{n})$ time. This dissertation introduces a newly developed system of algorithms called the Data Analyzing Tree (DAT) which is designed to either reduce the time complexity or produce more accurate results. DAT-1 uses O $(n\sp2)$ time to produce the same results as the normal data analysis method, and DAT-2 produces the …

Normal And Pathological Breakdown In Arabic., Sabah Safi-Stagni Jan 1992

Normal And Pathological Breakdown In Arabic., Sabah Safi-Stagni

LSU Historical Dissertations and Theses

The grammatical structure of Arabic allows for significant cross-linguistic comparisons in the study of Slips-of-the-tongue as well as aphasia. The dissertation presents a case study of the aphasic deficit in the speech of a speaker of Arabic, in particular, the Hijazi dialect spoken in the Western Province of Saudi Arabia, with a subsequent comparison with regular slips-of-the-tongue in the same dialect collected and analyzed by the same author. Both the slips-of-the-tongue data and the aphasia data have been collected in the city of Jeddah, Saudi Arabia, by the present investigator. It was observed that in such a highly inflected language, …

Stratigraphic Architecture Of An Extensional Orogen: The Mojave Extensional Belt, Southern California., Christopher John Travis Jan 1992

Stratigraphic Architecture Of An Extensional Orogen: The Mojave Extensional Belt, Southern California., Christopher John Travis

LSU Historical Dissertations and Theses

Field-based studies and quantitative models provide new insights into the stratigraphic architecture of a developing continental extensional orogen. The early Miocene age Mojave Extensional Belt of southern California (MEB) exhibits a tripartite stratigraphy, consisting of (1) pre- to early synextension volcanic deposits, unconformably overlain by (2) syntectonic basement-derived megabreccia and breccia with local finer-grained units, overlain by (3) a posttectonic fining-upward sequence of gravel, sand, shale, and limestone. On a more local scale, stratigraphy and sediment dispersal within the MEB reflect the evolution of the major tectonic elements of the belt: (1) Breakaway zone. Strata of the western Newberry Mountains …

Internal Labor Markets: Labor Process And Market Power Effects., Rebecca Grace Long Jan 1992

Internal Labor Markets: Labor Process And Market Power Effects., Rebecca Grace Long

LSU Historical Dissertations and Theses

This study contends that previous investigations into the nature of internal labor markets have been hampered by their dependence on various macro-level variables (e.g., sectors, industries, strategies) that ignore the often wide variation of employment arrangements within individual firms. It proposes that a better understanding of the employment arrangements associated with individual jobs may be gained by not only examining a job's technological components, but also the relative power of a firm's various coalitions. The data used in the reported study were acquired from the headquarters of the U.S. Bureau of Employment and Training's Occupational Field Analysis Centers in Raleigh, …

Musical Invention And Poetry In The Late Vocal Works Of Anton Webern., Melanie S. Kronick Jan 1992

Musical Invention And Poetry In The Late Vocal Works Of Anton Webern., Melanie S. Kronick

LSU Historical Dissertations and Theses

From the time of his composition of Op. 23 (1933-34) until his death, Anton Webern composed a series of important twelve-tone vocal works whose texts are drawn exclusively from the poetry of Hildegard Jone. Yet Webern scholars typically ignore the texts of these works when analyzing the scores in which the poems are embedded. My discussion shows, however, that Webern made important musical choices as a result of the poetic content of his texts. While Jone's poems are plentiful in metaphors of natural phenomena and images from German romantic poetry, I argue that they are concerned as much with poetic …

Behavioral Influences On Predator-Prey Interactions Between Juvenile Teleosts And Meiofauna., John Nathan Mccall Jan 1992

Behavioral Influences On Predator-Prey Interactions Between Juvenile Teleosts And Meiofauna., John Nathan Mccall

LSU Historical Dissertations and Theses

Predator-prey relationships between post-larval and juvenile teleosts are greatly influenced by the manner in which feeding behavior of fish interacts with the behavior of meiofaunal prey. Juvenile starry flounder (Platichthys stellatus Pallas) in a southeastern Alaskan bay fed disproportionately on the harpacticoid copepod Microarthridion littorale (Poppe), particularly on males. This apparent selectivity was not due to differing vertical distribution of harpacticoid species or to feeding in other locations. Comparison of ingested prey to harpacticoid assemblages collected by various techniques (including near-bottom collections) suggested that the prey selection shown by starry flounder may be the result of emergent behavior of its …

A Computational Framework For Efficient Error Correcting Codes Using An Artificial Neural Network Paradigm., Maung Maung Htay Jan 1992

A Computational Framework For Efficient Error Correcting Codes Using An Artificial Neural Network Paradigm., Maung Maung Htay

LSU Historical Dissertations and Theses

The quest for an efficient computational approach to neural connectivity problems has undergone a significant evolution in the last few years. The current best systems are far from equaling human performance, especially when a program of instructions is executed sequentially as in a von Neuman computer. On the other hand, neural net models are potential candidates for parallel processing since they explore many competing hypotheses simultaneously using massively parallel nets composed of many computational elements connected by links with variable weights. Thus, the application of modeling of a neural network must be complemented by deep insight into how to embed …

Monopoles And Confinement In Lattice-Gauge Theory., Vandana Singh Jan 1992

Monopoles And Confinement In Lattice-Gauge Theory., Vandana Singh

LSU Historical Dissertations and Theses

The mechanism by which quarks, believed to be the fundamental constituents of matter, are prevented from existing in the free state is still unknown. The phenomenon of quark confinement is one of the fundamental problems in physics. One of the most viable candidates for a hypothesis of confinement is the dual superconductor mechanism that likens quark confinement to the Meissner effect in superconductors. The peculiarities of quark interactions make a numerical approach to the subject a necessity, and therefore, much of the work in this area has been done through the methods of lattice gauge theory, with the simplicities afforded …

A Study On The Aquic Conditions Of Two Natraqualfs In The Coastal Plain Of Louisiana., Ariel Alejandro Szogi Jan 1992

A Study On The Aquic Conditions Of Two Natraqualfs In The Coastal Plain Of Louisiana., Ariel Alejandro Szogi

LSU Historical Dissertations and Theses

This study had the purposes of investigating the aquic conditions of two selected Natraqualfs to define the relationship between wetness and morphological properties and prediction of major soil processes. The proposed criteria for aquic conditions as defined by the International Committee on Aquic Conditions (ICOMAQ) were identified by: (i) presence of redoximorphic features, and (ii) measurement of saturation and reduction. They were used to locally verify morphological inferences used to predict the aquic conditions. Morphological properties and laboratory analysis were used to predict the periodicity and duration of saturation and reduction. Soil and ground water analyses were used to understand …

Studies On Escherichia Coli Cell Division: Overexpression, Purification, And Quantitative Determination Offtsa Protein., Haichao Wang Jan 1992

Studies On Escherichia Coli Cell Division: Overexpression, Purification, And Quantitative Determination Offtsa Protein., Haichao Wang

LSU Historical Dissertations and Theses

FtsA is an essential cell division protein which is synthesized in minute amounts in Escherichia coli. To study the effects of overexpressing ftsA on the phenotype of E. coli cells, DNA fragments encoding the ftsA gene were subcloned downstream of a lac or a tac promoter in two plasmids. High-level expression of the ftsA gene from these promoters inhibited normal cell septation and caused the cells to become long, nonseptate filaments. Continued overexpression of ftsA resulted in the filaments developing spherical bulges up to 4 um in diameter. It is suggested that these bulges may emanate from septation sites because …

Codependency Issues In Selected Contemporary American Plays., Jill Stapleton Bergeron Jan 1992

Codependency Issues In Selected Contemporary American Plays., Jill Stapleton Bergeron

LSU Historical Dissertations and Theses

Codependency is defined in this study as a disease characterized by individual adult inability to function in everyday life, in particular regards to personal relationships with others, in a healthy and self-loving manner. The study points to the works of several prominent theorists and practitioners in this field, such as John Bradshaw, Sharon Wegscheider-Cruse, Anne Wilson Schaef, and John and Linda Friel, as authoritative resource material on the subject. Being progressive in nature, codependency eventually leads to a host of severe personality and physical disorders, and usually to some form of suicide. The study points to abusive treatment in childhood--either …

Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton Jan 1992

Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton

LSU Historical Dissertations and Theses

Although some of the most recent work in the field of multicultural education has acknowledged and begun to theorize about what has been called the new cultural politics of difference, problems concerning the very notions of marginality, boundaries, and their accompanying "essentialist" thought remain undertheorized. It is my intention to bring discussions about marginality and essentialism from literary theory, feminist psychoanalytic theory and poststructuralist philosophy more explicitly into the conversation about multicultural curriculum theorizing. In this study I have attempted to further develop this conversation around notions of "translation" as generated by philosophers Michel Serres (1982) and John Rajchmann (1991) …

Soot Suppressing Mechanisms Of Iron In Premixed Hydrocarbon Flames., David Worthington Hahn Jan 1992

Soot Suppressing Mechanisms Of Iron In Premixed Hydrocarbon Flames., David Worthington Hahn

LSU Historical Dissertations and Theses

In-situ light scattering measurements are combined with chemical analysis of sampled soot particles to elucidate the mechanisms through which iron addition affects soot formation and growth processes in fuel-rich, premixed propane and oxygen flames. Soot particle optical inhomogeneity resulting from the addition of iron is accounted for in the light scattering analysis using an effective refractive index model. The influence of iron addition on soot particle diameters, number densities, volume fractions, surface areas, and specific growth rates is investigated. In addition, X-ray photoelectron spectroscopy was used to determine the chemical state of iron species throughout the flame. The analysis revealed …

Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory Jan 1992

Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory

LSU Historical Dissertations and Theses

It has been suggested that human beings do not possess social reality so much as they actively and cooperatively construct it by means of language in interaction with others. The manipulation of symbols, the creation of inferences, the posturing of one's personal identity all work together to enable participants (both speakers and hearers) in a given speech event to create social reality and reaffirm and maintain their social relationships. In religious speech communities, like the one investigated in this study, participants seek to create a different kind of social reality--one that encompasses all of the individual and corporate experiences of …

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford Jan 1992

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford

LSU Historical Dissertations and Theses

Automatic history matching is refined in this work by expanding the objective function and incorporating reservoir characteristics in the process of parameter selection. Iso-value contours are used to incorporate reservoir characteristics within history-matching parameters. These improvements are implemented in an automatic history-matching algorithm, OPTIM, that is coupled with BOAST II. Case histories of both hypothetical and real reservoirs demonstrated the effectiveness of incorporating reservoir characteristics in automatic history-matching parameters.

Diagnostic Techniques For Detection Of Permethrin-Resistant Soybean Loopers, Pseudoplusia Includens (Walker), Determination Of The Impact Of Insecticide Treatments On Age-Specific Mortality And Feeding Activity, And Estimation Of Field Control., Jeffrey Scott Mink

LSU Historical Dissertations and Theses

A glass vial bioassay was developed to detect permethrin resistance in soybean looper, Pseudoplusia includens (Walker), larvae. Third, fourth, fifth, and sixth instar soybean loopers from laboratory (susceptible) and field strains were exposed to several concentrations of permethrin in 20 ml glass vials. LC$\sb{50}$'s for third, fourth, and fifth instars from each field strain were not significantly different. A discriminating concentration of 0.5 $\mu$g permethrin per vial was identified for detection of permethrin resistance in soybean looper field populations. Field strains from cotton-soybean agroecosystems exhibited higher levels of resistance than strains from soybean-corn agroecosystems. The reliability of the vial bioassay …

A Comparison Of Language And Graphic Products Of Students From Kindergarten Classrooms Differing In Developmental Appropriateness Of Instruction., Jean Germany Mosley

LSU Historical Dissertations and Theses

This study examines the ways in which kindergartners from more and less developmentally appropriate classrooms negotiate the process of graphic communication. Both quantitative and qualitative aspects of this process are examined. Eighty-one kindergarten children from four classrooms were asked to tell a story both verbally and graphically. They were encouraged to include drawing, writing, or both on their paper. Then they were asked to tell the story that they had produced graphically. The children were students in one of four classrooms from a single school system that were identified as: (a) most developmentally appropriate beliefs and practices; (b) developmentally appropriate …

The Stability Of Thick, Self-Gravitating Disks In Protostellar Systems., John William Woodward Jan 1992

The Stability Of Thick, Self-Gravitating Disks In Protostellar Systems., John William Woodward

LSU Historical Dissertations and Theses

We perform a computational survey of the stability of protostellar systems which contain a self-gravitating disk. The systems are initially represented by a point mass $M\sb{c}$ at the center and a geometrically thick, axisymmetric disk of mass $M\sb{d}$ that supports uniform specific angular momentum and obeys an n = 3/2, polytropic equation of state. The equilibrium disk structure is uniquely defined upon the specification of two key dimensionless system parameters: $M\sb{d}/M\sb{c}$ and $T/\vert W\vert$ (the ratio of rotational kinetic energy of the disk to the gravitational potential energy of the system). The focus of this work is the identification of …

American Civil Religion And The Presidential Rhetoric Of Jimmy Carter., Michael James Adee Jan 1992

American Civil Religion And The Presidential Rhetoric Of Jimmy Carter., Michael James Adee

LSU Historical Dissertations and Theses

Scholars have long speculated about the role of American civil religion and political discourse. Of particular interest to rhetorical scholars is the function of a civil religion idiom within presidential discourse. The cornerstone of this study is founded upon Rod Hart's ideas in The Political Pulpit (1977) wherein the nature of American civil religion is described through the metaphor of a legal contract. A rhetorical approach to civil religion provides the framework for this study. Nine major public speeches by Carter as candidate and president, from 1974 to 1979, are examined in order to locate and identify the symbolic breeches …

The Rhetoric Of Redemption: A Development Of Kenneth Burke's Theory Of Guilt-Purification-Redemption And Its Application To Martin Luther King, Jr.'S "I Have A Dream" Speech., David A. Bobbitt Jan 1992

The Rhetoric Of Redemption: A Development Of Kenneth Burke's Theory Of Guilt-Purification-Redemption And Its Application To Martin Luther King, Jr.'S "I Have A Dream" Speech., David A. Bobbitt

LSU Historical Dissertations and Theses

This dissertation presents an exposition and development of Kenneth Burke's theory of guilt-purification-redemption (also referred to as the "redemption drama"), and then an application of that theory through a critical analysis of Martin Luther King, Jr.'s "I Have a Dream" speech. King's speech is treated as the "representative anecdote" of the moderate wing of the first phase of the civil rights movement. The speech became an authorizing text on race relations and provided the movement with an articulation of its logic and narrative form. Usually Burke's theory is seen as positing two primary modes of purification of guilt: victimage and …

The Theatre Of Religion: Jimmy Swaggart Within American Myth Discourse., Terry Grant Byars Jan 1992

The Theatre Of Religion: Jimmy Swaggart Within American Myth Discourse., Terry Grant Byars

LSU Historical Dissertations and Theses

This study explores the myth of the self-made man in American popular culture and how Jimmy Swaggart, the renowned televangelist, manipulates this myth in representing himself as an American hero. Central to such inquiry is Swaggart's use of theatrical device in promoting his heroism. Three fundamental questions provide the focus for investigation: (1) How in general does the creation of myth serve the needs of culture? (2) How specifically does the myth of self-made-ness benefit American culture? and (3) How is Swaggart able to participate in this powerful myth (especially using theatrical modes) in order to gain cultural sanction? In …

Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell Jan 1992

Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell

LSU Historical Dissertations and Theses

Western culture, in large part, is a product of scientific inquiry, technological development and the ability to harness some of nature's resources. Much of society looks to science for technology-related solutions to many of its ills. As it develops new technology, science necessarily seeks to understand and control the forces of nature. Although science assumes a prominent role in contemporary society, that prominence does not necessarily translate into cultural consensus on the progress achieved by technological developments. Another perspective is represented by those who contend that continued technological advancement is the source of existing problems, not the solution. As these …
