The Prediction Of Financial Turnaround Of Financially Distressed Firms., Leslie B. Fletcher Jan 1993

The Prediction Of Financial Turnaround Of Financially Distressed Firms., Leslie B. Fletcher

LSU Historical Dissertations and Theses

There is little extant accounting research on the turnaround phenomenon, when a financially distressed firm regains its financial health rather than merging with another firm or filing for protection under the Bankruptcy Act. The goal of this research was to determine whether financial and other publicly available information could be used to predict whether or not a distressed firm would turn around. To achieve that goal, a sample of distressed firms was identified based on their initial rather than final financial condition. A measure external to the firm--Standard and Poor's earnings and dividend ranking for common stock--was used to identify …

Analysis Of A Multidimensional Model Of Body Image Disturbance Using Structural Modeling., David Hunter Gleaves Jan 1993

Analysis Of A Multidimensional Model Of Body Image Disturbance Using Structural Modeling., David Hunter Gleaves

LSU Historical Dissertations and Theses

Although there has been a wealth of recent research on the construct of body image disturbance, it is still a highly controversial and poorly understood phenomenon. Much of previous research has treated body image disturbance as if it were a unidimensional construct. Recently, a multidimensional model was proposed which incorporated the concepts of body size distortion, preference for thinness, body dissatisfaction, and fear of fatness. The purpose of the present investigation was to examine this multidimensional model in an attempt to establish its validity and resolve many of the current controversies regarding body image disturbance. The LISREL 7 program was …

Reliability And Validity Of The Teen Substance Abuse Rating Scale., Brett Elliott Hemstreet Jan 1993

Reliability And Validity Of The Teen Substance Abuse Rating Scale., Brett Elliott Hemstreet

LSU Historical Dissertations and Theses

This study used 57 adolescent substance abusers receiving treatment and 510 adolescent controls in a validation of the Teen Substance Abuse Rating Scale (TSARS; Hemstreet, 1991). The TSARS was originally designed as a relatively brief, easy to read self-report questionnaire to discriminate between adolescent substance abusers and nonabusers. The 92 items of the TSARS represent specific behaviors that are answered in a Yes/No format. The TSARS was examined to determine if it would meet validity criteria presented by Winters (1990) and Swadi (1990), as well as those presented in the Standards for Educational and Psychological Testing (APA, 1985). A principal …

Highly Resolved Studies Of Vacuum Ultraviolet Photoionization Dynamics., Sandeep Kakar Jan 1993

Highly Resolved Studies Of Vacuum Ultraviolet Photoionization Dynamics., Sandeep Kakar

LSU Historical Dissertations and Theses

We use measurements of dispersed fluorescence from electronically excited photoions to study fundamental aspects of intramolecular dynamics. Our experimental innovations make it possible to obtain highly resolved photoionization data that offer qualitative insights into molecular scattering. In particular, we obtain vibrationally resolved data to probe coupling between the electronic and nuclear degrees of freedom by studying the distribution of vibrational energy among photoions. Vibrationally resolved branching ratios are measured over a broad spectral range of excitation energy and their non-Franck-Condon behavior is used as a tool to investigate two diverse aspects of shape resonant photoionization. First, vibrational branching ratios are …

The Phylogeny Of The Prasinophyceae And Pleurastrophyceae (Chlorophyta) Inferred From Ribosomal Rna Genes And Morphology., Thomas Sinclair Kantz Jan 1993

The Phylogeny Of The Prasinophyceae And Pleurastrophyceae (Chlorophyta) Inferred From Ribosomal Rna Genes And Morphology., Thomas Sinclair Kantz

LSU Historical Dissertations and Theses

The phylogeny of the problematic green algal classes Prasinophyceae and Pleurastrophyceae (Chlorophyta) sensu Mattox and Stewart (1984) was inferred from ultrastructural and biochemical data, and from ribosomal RNA gene sequence data. Analysis of a data set of ultrastructural and biochemical characters (with a predominance of flagellar and cell covering features) revealed a monophyletic Pleurastrophyceae and a monophyletic Prasinophyceae. Rerooting experiments indicated that the ancestral flagellate was likely Pedinomonas-like or Mamiellales-like. The cladograms generated from the ribosomal RNA gene sequence data show that the Pleurastrophyceae is not monophyletic; however, pleurastrophycean taxa are more closely related to the Chlorophyceae than to any …

Optimal Design Of A Fully Parallel Robot Manipulator., Chan Soo Kim Jan 1993

Optimal Design Of A Fully Parallel Robot Manipulator., Chan Soo Kim

LSU Historical Dissertations and Theses

Optimal design of a six degrees-of-freedom, fully parallel manipulator, called a Stewart platform is investigated. In order to optimize the mechanism, new performance measures are introduced since use of the previous methods suffer from lack of physical meaning due to dimensional inhomogeneity. To overcome the dimensional inhomogeneity problem, an Euclidean norm definition of each output space with homogeneous dimension is used to find input-output norm relation. As a result, four sets of eigenvalues are obtained which characterize translational and rotational velocity, force and torque, and position and orientation accuracy. From the four sets of eigenvalues, four determinant measures are defined, …

Magnetic Field Dependence Of The Specific Heat Of A Heavy Fermion System., Jai Won Kim Jan 1993

Magnetic Field Dependence Of The Specific Heat Of A Heavy Fermion System., Jai Won Kim

LSU Historical Dissertations and Theses

One of the distinguishing characteristics of heavy Fermion materials is the extraordinarily large size of the electronic specific heat at low temperatures. It is also observed that in some cases, the specific heat is reduced drastically by an external magnetic field. We show that this behavior can be simulated by using the non-degenerate lattice Anderson model on a 4-site tetrahedral cluster. Interactions included in the model are the on-site Couloumb repulsion between electrons in the f-orbital and the off-site spin conserving hybridization between electrons in the conduction and the f-orbitals. Our calculation is done by using the exact diagonalization method. …

A Blackboard Integration Of Manufacturing Databases Using An Intelligent Interface., David Anderson Koonce Jan 1993

A Blackboard Integration Of Manufacturing Databases Using An Intelligent Interface., David Anderson Koonce

LSU Historical Dissertations and Theses

The explosion of computer applications into the world of manufacturing along functional lines has produced the often mentioned "islands of automation." Although many issues and problems are involved in interfacing and integrating the databases that serve these applications, we can extract valuable data from these independent systems to provide important information to decision makers. This research resulted in the development of MIMIR (Multiple Integrated Manufacturing Information Resources), a decision support system based upon the blackboard architecture. The blackboard architecture extends the common expert system design to include multiple expert systems, termed Knowledge Sources (KS's), which combine to solve problems too …

Two Essays On Liquidity Suppliers' Gross Profits., Jie-Haun Lee Jan 1993

Two Essays On Liquidity Suppliers' Gross Profits., Jie-Haun Lee

LSU Historical Dissertations and Theses

The purpose of this dissertation is to examine the strategic behavior of the specialist proposed by Glosten (1989) and its implications for price volatility and market liquidity. The extant literature suggests that the bid-ask spread is responsible, at least in part, for the greater volatility and more negative autocorrelation at the open than at the close. We find that these phenomena are not related to the bid-ask spread, but related to pricing errors quoted by the specialist or by limit order traders around the open. We use George, Kaul, and Nimalendran's (1991) model, which is less biased than Roll's (1984) …

A Study Of Collaborative Consultation Versus Traditional Methods Of Special Education Service Delivery., Jane Nell Guyer Luster Jan 1993

A Study Of Collaborative Consultation Versus Traditional Methods Of Special Education Service Delivery., Jane Nell Guyer Luster

LSU Historical Dissertations and Theses

This study examined the attitudes and perceptions of general and special educators engaged in collaborative consultation and those utilizing traditional self-contained or resource methods of special education service delivery. A difference in collaborative consultation and traditional educators was predicted on autonomy, as measured by Charters' (1974) Sense of Autonomy Scale (SAS), zone of acceptance, as measured by the Professional Zone of Acceptance Inventory (PZAI) (Kunz and Hoy, 1974), and pluralistic ignorance, as measured by the Pupil Control Ideology (PCI) form developed by Willower, Eidell, and Hoy (1967). School climate was measured using the Organizational Climate Description Question-Revised Elementary (OCDQ-RE) (Hoy …

Personal Narrative: Revealing Self And Reflecting Other., Charla Lee Markham Shaw Jan 1993

Personal Narrative: Revealing Self And Reflecting Other., Charla Lee Markham Shaw

LSU Historical Dissertations and Theses

Self-presentation is a response to internal and external demands for self-verification. The telling of personal narratives is one form of presenting self to others that begins early in life, and crosses racial, ethnic, and cultural boundaries. Not only do we present ourselves through narrative, those with whom we are socially involved present us to others through narrative. The primary purpose of this study was to examine how well one's perception of self is communicated to familiar others. Secondarily, this study explored the impact of sex differences and relationship type on the success of this communication. One hundred targets each brought …

Linkage By Generically Gorenstein Cohen-Macaulay Ideals., Heath Mayall Martin Jan 1993

Linkage By Generically Gorenstein Cohen-Macaulay Ideals., Heath Mayall Martin

LSU Historical Dissertations and Theses

In a Gorenstein local ring R, two ideals A and B are said to be linked by an ideal I if the two relations A = (I: B) and B = (I: A) hold. In the case that I is a complete intersection, or a Gorenstein ideal, it is known that linkage preserves the Cohen-Macaulay property. That is, if A is a Cohen-Macaulay ideal, then so is B. However, if I is allowed to be a generically Gorenstein, Cohen-Macaulay ideal, easy examples show that this type of linkage does not preserve the Cohen-Macaulay property. The primary purpose of this work …

Positionality, Structure, And Conflict In The International System., Michael Henry Murdoch Jan 1993

Positionality, Structure, And Conflict In The International System., Michael Henry Murdoch

LSU Historical Dissertations and Theses

This dissertation brings a disaggregated structural approach to bear on two dependent variables--trade protectionism and interstate war. In trade, I utilize cross-sectional data on tariffs and non-tariff barriers to test the theory that states are positional actors who use protectionist measures in an attempt to acquire or defend comparative advantage in industrial sectors. States and two-digit SITC industrial sectors are positioned in the international division of labor. A model is developed that predicts how states should distribute their protection across sectors if protection is a function of state positionality, as opposed to state institutions or other non-structural variables. Although the …

Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles Jan 1993

Concept Circle Diagrams: A Metacognitive Learning Strategy To Enhance Meaningful Learning In The Elementary Science Classroom., Connie Sue Nobles

LSU Historical Dissertations and Theses

The purpose of this study was to explore the use of concept circle diagrams, a newly developed metacognitive strategy (Wandersee, 1987), for meaningful science learning. Two research questions were: (a) Do concept circle diagrams enhance the identification and learning of science concepts more than traditional learning methods? and (b) Do concept circle diagrams evolve in quality within and across three sequences of direct explanation, guided practice, and independent practice? This study builds upon earlier research on two important metacognitive strategies, Vee diagrams (Gowin, 1981) and concept mapping (Novak & Gowin, 1984), used in science education. Participants were members of two …

Phase Transitions And Flux Distributions Of Su(2) Lattice Gauge Theory., Yingcai Peng Jan 1993

Phase Transitions And Flux Distributions Of Su(2) Lattice Gauge Theory., Yingcai Peng

LSU Historical Dissertations and Theses

The strong interactions between quarks are believed to be described by Quantum Chromodynamics (QCD), which is a non-abelian SU(3) gauge theory. It is known that QCD undergoes a deconfining phase transition at very high temperatures, that is, at low temperatures QCD is in a confined phase, at sufficient high temperatures it is in a unconfined phase. Also, quark confinement is believed to be due to the string formation. In this dissertation we studied SU(2) gauge theory using numerical methods of LGT, which will provide some insights about the properties of QCD because SU(2) is similar to SU(3). We measured the …

The Absent Father In Modern Drama., Paul Nagim Rosefeldt Jan 1993

The Absent Father In Modern Drama., Paul Nagim Rosefeldt

LSU Historical Dissertations and Theses

Theories of modern drama point out the powerful sense of loss and alienation that is woven into the very fabric of modern drama. This sense of loss is connected with the death of God and the destruction of absolute value systems. This study, however, takes the theory of loss one step further, tying the absence of God in modern drama to the absence of the father. The psychoanalytical theories of Sigmund Freud, Jacques Lacan, and Carl Jung view the father as a disembodied presence standing above and outside of culture. These psychological theories of the father can be connected to …

The Dynamics Of Collective Farming: A Case Study Of Fish Farm Cooperatives In The Prefectures Of Butare And Gikongoro, Rwanda., Alphonse Rubagumya Jan 1993

The Dynamics Of Collective Farming: A Case Study Of Fish Farm Cooperatives In The Prefectures Of Butare And Gikongoro, Rwanda., Alphonse Rubagumya

LSU Historical Dissertations and Theses

Cooperative fish farming not only insures a wider distribution of land and fish farming technology resources to larger segments of the population, but also makes possible the integration of limited individual resources into sizable and economically more viable production and marketing units. On the basis that more efficient internal organization can lead to greater cooperative performance, the purpose of this study is to identify organizational attributes and practices associated with effectiveness of fish farming cooperatives in Rwanda. Data for the study were obtained from a sample of 200 fish farm groups selected in the prefectures of Butare and Gikongoro, Rwanda. …

Remagnetization Of Carbonates In The Appalachian Basin., Barbara Saffer Jan 1993

Remagnetization Of Carbonates In The Appalachian Basin., Barbara Saffer

LSU Historical Dissertations and Theses

Paleomagnetic and rock magnetic data from two transects of southern and northern Appalachian Basin carbonates demonstrate different patterns of Late Paleozoic remagnetization and magnetite concentration. Samples were collected in Ordovician and Mississippian carbonates of Tennessee and Alabama and in Devonian carbonates of New York and Ontario. In the southern basin, Paleozoic carbonates of the Nashville Dome and of the fold-thrust belt near Chattanooga were remagnetized during the Late Paleozoic Kiaman period. These remagnetized carbonates contain more magnetite than do unremagnetized carbonates in the intervening basin. The unremagnetized carbonates demonstrate only a present field magnetization except for one Mississippian site in …

Three-Dimensional Large-Scale Coherent Structures In A Developing Plane Mixing Layer., Taewon Seo Jan 1993

Three-Dimensional Large-Scale Coherent Structures In A Developing Plane Mixing Layer., Taewon Seo

LSU Historical Dissertations and Theses

A theoretical investigation of the role of three-dimensional large-scale structures and their mutual interactions in a developing, plane mixing layer subjected to external forcing is presented. Large-scale structures are decomposed into 3 fundamental and 2 subharmonic wave modes. Two fundamentals and one subharmonic are three-dimensional. Linear stability of the three-dimensional, viscous shear layer is formulated and solved as the basis for the solution of a nonlinear formulation based on an energy method. This method leads to a set of nonlinearly-coupled, ordinary differential equations governing the evolution of modal energies and phases, and of the shear layer thickness. A parametric study …

Effect Of Planting Date And Other Management Inputs On Production Of Wheat., Syed Asif Hussain Shah Jan 1993

Effect Of Planting Date And Other Management Inputs On Production Of Wheat., Syed Asif Hussain Shah

LSU Historical Dissertations and Theses

Intensive cereal management (ICM) can optimize the yield and performance of winter wheat (Triticum aestivum L. emend. Thell.). Planting is often delayed beyond the optimum date along the Gulf Coast due to frequent precipitation. Field experiments were conducted at four locations in 1991 and two locations in 1992 to evaluate the effects of intensive management practices on performance of wheat planted at recommended and post-recommended dates. Seeding rates of 84 or 168 kg ha$\sp{-1}$ and topdress N rates of 90 or 90 + 45 kg ha$\sp{-1}$ were evaluated for an early and a late-maturing cultivar planted at a recommended date …

Dynamic Properties Of Interacting Electrons., Lun Tan Jan 1993

Dynamic Properties Of Interacting Electrons., Lun Tan

LSU Historical Dissertations and Theses

The spectral weight functions and the optical conductivity of a highly correlated electronic system described by a simple Hubbard model are studied. The calculations are carried out for a small system, a cubic cluster of eight sites, by means of exact diagonalization using symmetrized basis functions. The spectral weight functions of a single hole (or electron) placed in an otherwise half-filled band are obtained. The density of states at different interaction strengths, ranging from weak to strong couplings, is studied. We observe the spreading of the spectral weight associated with some single-particle eigenstates over a large range of energies, and …

A Monte Carlo Method In Contribution Response Transport., Charles Habib Aboughantous Jan 1993

A Monte Carlo Method In Contribution Response Transport., Charles Habib Aboughantous

LSU Historical Dissertations and Theses

A contribution response Monte Carlo method is developed and successfully applied to a sample deep penetration shielding problem. The random walk is simulated in most of its parts like in conventional M.C. by introducing the concept of a fictitious response particle. The scoring is peculiar to the proposed method and it need not be made at the detector itself so that computing time can be reduced by an order of magnitude or more depending on the geometry of the problem. The probability density functions are natural. They possess properties not encountered in conventional M.C. methods currently in use. The selection …

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander Jan 1993

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander

LSU Historical Dissertations and Theses

"The Poetry In-Between: Presence and Absence in Whitman, Rimbaud, and Hopkins" analyzes three major nineteenth-century poets and their development of a poetics which has as its chief focus of concern the issue of presencing an eternal and universal "Other" by which to assess self identity. After the Kantian critique and the seeming reduction of human knowledge to phenomenal perceptions, early nineteenth-century poets and theorists feared the entrapment and isolation of the self in subjective awareness. The romantics, such as Friedrich Schlegel, sought ways to overcome such alienating subjectivity and ultimately conceived of the poet as a privileged spokesman and arbiter …
