Wavelet-Based Registration Of Medical Images., Raj Sharman
Wavelet-Based Registration Of Medical Images., Raj Sharman
LSU Historical Dissertations and Theses
Registration is the process of spatially aligning two objects and is normally a preprocessing step in most object recognition algorithms. Registration of images and recognition of signatures of objects in images is important for clinical and diagnostic purposes in medicine. Recognizing structure, potential targets for defense purposes and changes in the terrain, from aerial surveillance images and SAR images is the focus of extensive research and development today. Automatic Target Recognition is becoming increasingly important as the defense systems and armament technology move to use smarter munitions. Registration of images is a preprocessing step in any kind of machine vision …
Vocational Education And Recidivism At The Louisiana Correctional Institute For Women., Henry Elbert Sanders Jr
Vocational Education And Recidivism At The Louisiana Correctional Institute For Women., Henry Elbert Sanders Jr
LSU Historical Dissertations and Theses
Recidivism is a phenomenon causing growing concern. When released criminals return to crime, the costs become immeasurable. Victims can never be adequately compensated for personal losses, and the nation cannot halt the spiraling costs of maintaining prisons housing mostly repeat offenders. The nation is spending upwards from 98 billion dollars on crime, annually. Public opinion opposes education for inmates, yet, with the nation's prisons operating near capacity, a millennium approaches that promises another wave of prison construction resulting in exponential leaps in the costs of incarceration. A marketing concept asserts that attracting people to a product is half the battle. …
Form: The Fortran Object Recovery Model. A Methodology To Extract Object-Oriented Designs From Imperative Code., Bonnie Lynn Achee
Form: The Fortran Object Recovery Model. A Methodology To Extract Object-Oriented Designs From Imperative Code., Bonnie Lynn Achee
LSU Historical Dissertations and Theses
A majority of legacy systems in use in the scientific and engineering application domains are coded in imperative languages, specifically, COBOL or FORTRAN-77. These systems have an average age of 15 years or more and have undergone years of extensive maintenance. They suffer from either poor documentation or no documentation, and antiquated coding practices and paradigms (Chik94) (Osbo90). The purpose of this research is to develop a reverse-engineering methodology to extract an object-oriented design from legacy systems written in imperative languages. This research defines a three-phase methodology that inputs source code and outputs an object-oriented design. The three phases of …
Living Arrangements Of The Elderly In The United States: Comparing Whites, Blacks, Hispanics, And Asians' Households., Kiyomi Ando
Living Arrangements Of The Elderly In The United States: Comparing Whites, Blacks, Hispanics, And Asians' Households., Kiyomi Ando
LSU Historical Dissertations and Theses
My dissertation analyzed the living arrangements of the elderly, focusing on differences across gender and racial/ethnic lines. Drawing upon rational choice and family solidarity theoretical perspectives. I derived hypotheses dealing with the effects of individual resources, cultural characteristics, and geographic context on the elderly's living arrangements. These hypotheses were empirically tested using logistic regression models to estimate the odds of the elderly choosing from among three options of living arrangements--independent living, joint living, and dependent living. Separate models were applied to non-Hispanic white, African American, Hispanic, and Asian subsamples. Data were from the 1990 Census Public Use Sample (PUMS-L). The …

A Normative Study Of The Psychopathology Instrument For Mentally Retarded Adults (Pimra)., Kelley Lynne Francis
LSU Historical Dissertations and Theses
Indices were established for the Psychopathology Instrument for Mentally Retarded Adults (PIMRA) to signify that a particular score warranted further assessment. The subjects were 431 individuals with mild and moderate mental retardation in state schools and developmental centers in Texas and Louisiana. Almost 65% of the sample met the cutoff for further assessment using the newly established criteria, while approximately 40% of the sample had elevations on two or more of the subscales. Critical items were identified for the Schizophrenia, Affective Disorders, Somatoform Disorders, and Adjustment Disorders subscales. No significant differences were noted for gender with respect to the subscales. …

The Clarity Of The Modern: Or, The Ambiguities Of Henry James And Wallace Stevens., Gregory Angelo Marks
The Clarity Of The Modern: Or, The Ambiguities Of Henry James And Wallace Stevens., Gregory Angelo Marks
LSU Historical Dissertations and Theses
Clarity, in all its various guises, was before the advent of Romanticism looked upon as an unquestioned focus of attention and irrefutable goal of human endeavor. Conversely, ambiguity was seen negatively: it was in language an obstacle to communication; in ethics, an indecisiveness failing action; and in ontology and aesthetics, a slovenly disorder. With Romanticism, this basic consensus regarding these terms ends. No longer an expression of censure, ambiguity is imagined as a liberatory force. Clarity, if attainable at all, is dismissed as mere rigidity. The works of Americans Henry James and Wallace Stevens embody and enact this tension and …
The Interactions Among The Subunits Of The Mcrbc Restriction System In E. Coli., Loganayaki Ganesh
The Interactions Among The Subunits Of The Mcrbc Restriction System In E. Coli., Loganayaki Ganesh
LSU Historical Dissertations and Theses
The McrBC system of Escherichia coli K12 restricts DNA containing modified cytosines within specific sites. The modified cytosines recognized may be 5-hydroxymethylcytosine, N$\sp4$-methylcytosine or 5-methylcytosine. In the mcrBC operon, the mcrB gene is expressed to produce the McrB$\sb{\rm L}$ protein (51 kDa) and the McrB$\sb{\rm S}$ protein (33kDa), which is translated from an inframe internal translation start site and lacks the N-terminal 161 amino acids of the long product. The McrC protein is a 39kDa protein and is required for the cleavage of most methylated substrates. Using a MalE-McrB$\sb{\rm L}$ fusion protein, the endonucleolytic McrB$\sb{\rm L}$ subunit was shown to …
Predicting Driving Ability In Alzheimer's Disease Patients., Judith Rosemary O'Jile
Predicting Driving Ability In Alzheimer's Disease Patients., Judith Rosemary O'Jile
LSU Historical Dissertations and Theses
Studies have shown that individuals with Alzheimer's disease have a greater number of automobile crashes than normal elderly controls. Assessment of driving ability is usually conducted by use of an on-the-road examination. These examinations are costly, time intensive, and sometimes dangerous. Finding other measures that are predictive of driving ability will enable screening of patients to decrease the number of on-road examinations. Alzheimer's disease patients and normal elderly control subjects were administered neuropsychological measures as well as the Driver Performance Test (DPT) and Driver Risk Index (DRI), both videotaped tests of driving knowledge and risk assessment. Driving histories based on …

Daniel Pratt Of Prattville: A Northern Industrialist And A Southern Town., Curt John Evans
LSU Historical Dissertations and Theses
This dissertation explores the life of Daniel Pratt, one of the South's most important industrialists. Daniel Pratt was born in Temple, New Hampshire on July 20, 1799. In 1821, he migrated to Jones County, Georgia, where he worked as a carpenter-architect for ten years. He married Esther Ticknor of Connecticut in 1827 Samuel Griswold hired Pratt in 1831 to superintend his cotton gin factory in Jones County. Two years later, Pratt migrated to Autauga County in central Alabama, where he started his own gin shop. In 1839, Pratt founded Prattville, located fourteen miles from Alabama's capital, Montgomery. The next year, …

The Structure And Stability Of Selected, 2-D Self-Gravitating Systems., Saied W. Andalib
The Structure And Stability Of Selected, 2-D Self-Gravitating Systems., Saied W. Andalib
LSU Historical Dissertations and Theses
Models of radially and vertically extended self-gravitating disks orbiting around a central point mass are relevant to the dynamics of astrophysical systems and are thought to be common in many galaxies. The gravity driven instabilities in these accretion disks are now believed to be a possible mechanism for star formation via disk fragmentation (Shu, Adams, & Lizano 1987, Adams, Rudin & Shu 1989; Christodoulou 1995). We quantify these regions of instability using a simple toroidal model of an accretion disk. We choose the two-dimensional axisymmetric, incompressible slender disks to examine and map out these principal modes of gravity driven instabilities. …
Structural Characterization Of Beta Carbonic Anhydrases From Higher Plants., Michael H. Bracey
Structural Characterization Of Beta Carbonic Anhydrases From Higher Plants., Michael H. Bracey
LSU Historical Dissertations and Theses
It is the goal of this dissertation research to reveal some aspects of the physical nature of spinach carbonic anhydrase as a representative $\beta$CA using the techniques of sequence comparison, molecular biology, and biophysics. Though both $\alpha$ and $\beta$ carbonic anhydrases are zinc dependent metalloenzymes, it is clear that the two isoforms do not adopt the same mechanism for coordinating the active site metal. While $\alpha$CA binds zinc through three histidine ligands, $\beta$CA cannot due to a lack of evolutionarily conserved histidines. Instead, the $\beta$ family has adopted a ligand scheme incorporating a single histidine and two cysteines. This has …
Locus Of Reform: From Reflection To Effectiveness Through The Voices Of Novice Teachers., Patricia Babin Caillouet
Locus Of Reform: From Reflection To Effectiveness Through The Voices Of Novice Teachers., Patricia Babin Caillouet
LSU Historical Dissertations and Theses
This descriptive multiple-case qualitative study focused on the professional and personal experiences of five novice teachers--three preservice student teachers and two first-year teachers. Research conducted in two exemplary elementary schools examined the following questions: (a) How do preservice and first-year teachers use reflective practice and self-assessment to develop effective teaching practices? (b) How do the preservice and first-year teachers' approaches to effective literacy instruction compare? (c) Why does reflection not translate into effectiveness? and (d) How is effectiveness perceived in the professional, social school environment of novice teachers? Results of the case studies determined that teacher education programs must go …
Evaluation Of The Toxicological Consequences Of Dietary Exposure To Individual Classes Of Polycyclic Aromatic Hydrocarbons Or A Mixture In The Fischer-344 Rat., Mary Durand Boudreau
Evaluation Of The Toxicological Consequences Of Dietary Exposure To Individual Classes Of Polycyclic Aromatic Hydrocarbons Or A Mixture In The Fischer-344 Rat., Mary Durand Boudreau
LSU Historical Dissertations and Theses
There is special concern about the potential health effects of by-products released into the environment after combustion or conversion of fossil fuels. Polycyclic aromatic hydrocarbons (PAH), while initially released largely into the atmosphere, are subsequently deposited in soil and water and on foods. Although the significance of PAH contamination with regard to environmentally caused diseases and cancer in humans is difficult to estimate, it is suggested that the potential hazards may be underestimated. In an effort to understand the potential adverse health effects of PAHs, a comprehensive study was undertaken to determine the metabolic fate of selected PAHs as individual …
On The Second Stiefel-Whitney Class Of Scaled Trace Forms Of Central Simple Algebras., Rosali Brusamarello
On The Second Stiefel-Whitney Class Of Scaled Trace Forms Of Central Simple Algebras., Rosali Brusamarello
LSU Historical Dissertations and Theses
In this work we compute the second Stiefel-Whitney class $w\sb2$ of the scaled trace form $Q\sb{A,a}(x)={\bf tr}\sb{A/k}(ax\sp2),$ where A is a central simple algebra over a perfect field k of characteristic different from two, $a\in A$ is a fixed element, and ${\bf tr}\sb{A/k}$ is the reduced trace. The first three chapters provide background material about quadratic forms, central simple algebras, group cohomology, and representations of linear algebraic groups. The fourth chapter presents two known results about the second Stiefel-Whitney class of trace forms: Serre's formula for the case of etale algebras and Saltman's formula for the case of central simple …
The Control Of Time In Renaissance England: Marlowe, Shakespeare, Jonson, And Donne., Eric C. Brown
The Control Of Time In Renaissance England: Marlowe, Shakespeare, Jonson, And Donne., Eric C. Brown
LSU Historical Dissertations and Theses
While critics have much analyzed the idea of time, they have left largely unchronicled an important Renaissance conception. Time the destroyer or devourer and time the creator or revealer of truth are familiar early modern tropes. But the inversion of this power structure--humanity not controlled by but controlling time--was equally pervasive. Especially apparent are inversions in which time is acted upon as an instrument objectified for use and abuse. Marlowe, Shakespeare, Jonson, and Donne all explore this notion of time as controllable instrument, alternately condemning or glorifying time's debasement, enfeeblement, subjugation, and manipulation. For Marlowe, the control of time manifests …
The Effects Of Fiscal Structure, Leviathan, And Interdependent Demands On Local Public Spending Behavior., Rebecca J. Campbell
The Effects Of Fiscal Structure, Leviathan, And Interdependent Demands On Local Public Spending Behavior., Rebecca J. Campbell
LSU Historical Dissertations and Theses
Understanding the fiscal behavior of subnational governments is increasingly important as fiscal responsibilities are devolved. In order to get a clearer picture of subnational government behavior, we employ a median voter model and local government data to perform tests of the fragmentation, decentralization, fiscal illusion, and overlapping jurisdictions hypotheses. A key theoretical result is that estimating horizontal effects of the leviathan and fiscal illusion models without accounting for the interdependent demands for the services of overlapping jurisdictions will result in upwardly biased estimates. We find that controlling for the overlapping jurisdictions relationship is important. This dissertation estimates each model using …
Dietary Nitrogen And Energy Metabolism In The Ruminant: Effect Of Source Of Nitrogen., Angelica Maris Chapa
Dietary Nitrogen And Energy Metabolism In The Ruminant: Effect Of Source Of Nitrogen., Angelica Maris Chapa
LSU Historical Dissertations and Theses
Three experiments were conducted to determine the effects of dietary nitrogen on the energy status of ruminants and the feasibility of using L-carnitine to prevent the negative effects associated with overfeeding nitrogen. The objectives of the first experiment were to monitor the nitrogen and energy status of cows grazing ryegrass pastures through the measurement of key blood metabolites and insulin and to determine the protein supplementation scheme which would maximize milk yield and maintain plasma urea nitrogen levels below dangerous levels. In the first experiment, the protein supplement that supplied excess total protein exerted negative effects on body condition and …
The Effects Of Gender And Race On Physician Treatment Of Patient Emotion., Vaughn A. Decoster
The Effects Of Gender And Race On Physician Treatment Of Patient Emotion., Vaughn A. Decoster
LSU Historical Dissertations and Theses
This study established theoretical and empirical foundations for the investigation into how physicians deal with (treat) patient emotion. The questions posed, "Do physicians employ specific strategies to treat patient emotion?" and "What are the effects of physician-patient social characteristics (gender and race) on emotion treatment?" Coalescing two seemingly incongruent perspectives (social constructionism and Kemper's social relational theory), I clarified the conceptual basis for the emotion management of other people. From these perspectives, I developed a three stage theory to describe and explain the physician treatment of patient emotion (triaging, diagnosing, and treatment), as well as appreciate the effects of social …
Supplemental Organic Chromium For Dairy Calves., Christopher L. Depew
Supplemental Organic Chromium For Dairy Calves., Christopher L. Depew
LSU Historical Dissertations and Theses
In Exp. 1, 42 calves were fed milk replacer and then starter either with or without 1 ppm supplemental chromium (Cr) as Cr-picolinate. Neither Cr nor sex affected growth performance. With the exception of plasma nonesterified fatty acid concentrations (NEFA), weekly plasma metabolites were not affected by Cr or sex. Pre- and postfeeding plasma NEFA concentrations were lower in Cr-fed calves, but were not affected by sex. AU calves seemed to become less insulin sensitive with age, as plasma glucose became lower and insulin higher as calves became older. During i.v. glucose tolerance tests (IVGTT), calves cleared glucose faster at …
An Investigation Of The Relationship Between Teachers' Orientations In Reading Process And Instruction: Four Case Studies., Carrice Lou Cummins
An Investigation Of The Relationship Between Teachers' Orientations In Reading Process And Instruction: Four Case Studies., Carrice Lou Cummins
LSU Historical Dissertations and Theses
The beliefs that teachers hold about how children learn are often reflected in the instructional practices they use to help children become readers. The purpose of this study was threefold: (a) to identify teachers' beliefs regarding how reading takes place and how reading develops, (b) to examine the instructional reading practices implemented in teachers' classrooms, and (c) to explore the relationships between teachers' theoretical beliefs and their instructional practices in providing appropriate reading instruction. Qualitative methods informed this study by providing case studies of four primary grade teachers, giving detailed accounts of their theoretical beliefs--process and instruction. Two of the …
The Role Of The Bass Trombone In Haydn's "Die Schoepfung", Beethoven's Ninth Symphony, And Brahms's Fourth Symphony: A Tutorial Focusing On Historical Background And Preparation Suggestions., Cassandra R. Fulmer
LSU Historical Dissertations and Theses
For bass trombonists today, as with other instrumentalists, the preparation of orchestral excerpts for auditions forms a vital part of training for a professional career. While there is ample information available on tenor trombone orchestral excerpts, little detailed study has been devoted specifically to excerpts for the bass trombone. Although research on the bass trombone has increased since the 1940s, there is a great need for concentrated study in the area of orchestral preparation strategies and performance. The purpose of this monograph is to provide a tutorial for undergraduate bass trombonists in the preparation of three orchestral works, developing practice …
A Knowledge-Based System For Reliability-Centered Maintenance In The Chemical Industry., Daniel Jesus Fonseca
A Knowledge-Based System For Reliability-Centered Maintenance In The Chemical Industry., Daniel Jesus Fonseca
LSU Historical Dissertations and Theses
An innovative new framework for the implementation of reliability centered maintenance (RCM) in industrial settings was developed and implemented during this study. Fuzzy reasoning algorithms were designed to evaluate and assess the likelihood of equipment failure mode precipitation and aggravation. Furthermore, an alternative to the traditional RCM decision tree for prioritizing equipment failure modes was defined through the development of an approximate reasoning scheme. This priority scheme not only takes into account the relevancy of failure modes on local and product effects, but also their possibility of occurrence, as well as associated negative consequences on adjacent machinery. The new RCM …

Characterization Ofp53 Gene Sequence In Exons 5-8 Of The Western Mosquito Fish, Gambusia Affinis., Neeraja Kondapi Erraguntla
LSU Historical Dissertations and Theses
Cancer is a multistage disease that involves both genetic and epigenetic factors. The number of physical and chemical agents with which human beings come in contact on a regular basis is increasing everyday. Somatic mutations can result due to such exposures and trigger uncontrolled cell division resulting in cancer. The p53 tumor suppressor gene has been identified in several vertebrate species ranging from man to fish. In addition, inactivation of p53 has been observed in a wide variety of tumors. Fish models are becoming increasingly popular for assessing environmental exposure. Low background incidence of mutations, relatively low cost tumor studies, …
Adjective Acquisition: Developmental Changes In The Use Of The Shape Bias, Syntax, Shape Consistency, And Semantic Attributes., Lenore Carol Frigo
Adjective Acquisition: Developmental Changes In The Use Of The Shape Bias, Syntax, Shape Consistency, And Semantic Attributes., Lenore Carol Frigo
LSU Historical Dissertations and Theses
When learning vocabulary, children must determine the meaning of each word that they hear. In hypothesizing about word meanings, children follow certain principles that simplify vocabulary acquisition. Among these principles are several that lead children to follow a shape bias. Under the shape bias, children assume that words extend to objects that share a common shape. This shape bias is useful for learning count nouns, which often include whole-object shape as an important aspect of meaning. However, the shape bias is not useful for the development of other word classes, such as adjectives. In this study, several variables were examined …
Analysis Of Taper-Taper Adhesive-Bonded Joints In Composite Plates Under Tension And Cylindrical Bending., Jack Elwin Helms Jr
Analysis Of Taper-Taper Adhesive-Bonded Joints In Composite Plates Under Tension And Cylindrical Bending., Jack Elwin Helms Jr
LSU Historical Dissertations and Theses
A taper-taper adhesive-bonded joint between two composite plates has been analyzed under tension and cylindrical bending. Two tension models were derived. The first model was based on mechanics of materials and the second model used laminated plate theory and shear correction factors. For the mechanics of materials model the condition of plane strain was assumed for the adherends and adhesive. Average stresses were used in the adherends and point-wise stresses were used in the adhesive. The model derived consisted of four second-order ordinary differential equations with variable coefficients. The adherends were characterized by the extensional Young's modulus. The equations were …
Parallelization And Implementation Of Approximate Root Isolation For Nonlinear System By Monte Carlo., Ebrahim Khosravi
Parallelization And Implementation Of Approximate Root Isolation For Nonlinear System By Monte Carlo., Ebrahim Khosravi
LSU Historical Dissertations and Theses
This dissertation solves a fundamental problem of isolating the real roots of nonlinear systems of equations by Monte-Carlo that were published by Bush Jones. This algorithm requires only function values and can be applied readily to complicated systems of transcendental functions. The implementation of this sequential algorithm provides scientists with the means to utilize function analysis in mathematics or other fields of science. The algorithm, however, is so computationally intensive that the system is limited to a very small set of variables, and this will make it unfeasible for large systems of equations. Also a computational technique was needed for …
Localization And Biochemical Characterization Of The Cell Division Protein Ftsa In Escherichia Coli., Anand Immaneni
Localization And Biochemical Characterization Of The Cell Division Protein Ftsa In Escherichia Coli., Anand Immaneni
LSU Historical Dissertations and Theses
Cell division protein, FtsA, is an inner membrane protein with a putative ATP binding motif. Although FtsA has been studied genetically, it has not been characterized biochemically. Immunoelectron microscopy with FtsA polyclonal antibodies permitted FtsA to be within the cell. Since native FtsA is present in low amounts, the cellular level of this protein was increased by induction of ftsA from an overexpression plasmid before processing the cells for immunogold labelling. The immunogold particles localized FtsA to the inner cytoplasmic membrane. Immunogold labelling of cells overproducing C-terminal deleted FtsA, displayed the gold particles throughout the cytoplasm. This suggested that the …
