Natalie Vivian Scott: The Origins, People And Times Of The French Quarter Renaissance (1920-1930)., John Wyeth Scott Ii Jan 1999

Natalie Vivian Scott: The Origins, People And Times Of The French Quarter Renaissance (1920-1930)., John Wyeth Scott Ii

LSU Historical Dissertations and Theses

This is the interwoven story of Natalie Vivian Scott, war hero, author, adventurer and humanitarian, and the French Quarter Renaissance during the 1920s, when Natalie Scott was a vital member of the talented coterie of writers and artists whose talents prospered there, including Sherwood Anderson, William Faulkner, William Spratling, Lyle Saxon, Roark Bradford, Oliver La Farge, John Dos Passos, Hamilton Basso, Meigs Frost, among others. This work's premise is that the decayed, crumbling French Quarter, falling into irreversible decline, was saved during the early 1920s by an outburst of local creativity and organizational energy that inspired restoration and a unique, …

Design Recovery And Data Mining: A Methodology That Identifies Data-Cohesive Subsystems Based On Mining Association Rules., Carlos Montes De Oca

LSU Historical Dissertations and Theses

Software maintenance is both a technical and an economic concern for organizations. Large software systems are difficult to maintain due to their intrinsic complexity, and their maintenance consumes between 50% and 90% of the cost of their complete life-cycle. An essential step in maintenance is reverse engineering, which focuses on understanding the system. This system understanding is critical to avoid the generation of undesired side effects during maintenance. The objective of this research is to investigate the potential of applying data mining to reverse engineering. This research was motivated by the following: (1) data mining can process large volumes of …

Magnetism Of Magnets: The Impact Of High School Magnet Programs On Desegregation And School Improvement In East Baton Rouge Parish., Alonzo Ray Luce

LSU Historical Dissertations and Theses

The movement of school desegregation plans from mandatory means to voluntary means has led to a fierce debate. The school desegregation problem is encapsulated by two competing strategies: making a plan that enforces racial balance, and making a plan that stops white flight. The purpose of this study was to describe how high schools in East Baton Rouge Parish implemented court approved magnet programs, and to examine the results brought about at each of the high schools in terms of desegregation and school improvement. The study was designed to answer the following research questions: (1) How have high schools in …

Petroleum Reservoir Simulation Using 3-D Finite Element Method With Parallel Implementation., Husam M. Yaghi Jan 1999

Petroleum Reservoir Simulation Using 3-D Finite Element Method With Parallel Implementation., Husam M. Yaghi

LSU Historical Dissertations and Theses

Modeling fluid flow around wellbores with conventional reservoir simulators is inaccurate because radial flow occurs in the vicinity of the wellbore and these simulators use cartesian coordinates. In this research, we present a more accurate wellbore simulation by incorporating the finite element method (FEM) to simulate the radial flow in the vicinity of the wellbore and interfacing this finite element wellbore model with an existing finite difference method (FDM) reservoir simulator. Although this technique was developed for a vertical well, it could also be used to accurately model a horizontal wellbore. This "hybrid" solution is for three dimensional---triphasic fluid flow …

A Novel Approach To Dna Sequencing Employing Near -Ir Fluorescence Detection Coupled With Microscale Reaction Vessels With Capillary Gel Separations., Daryl Clifford Williams Jan 1999

A Novel Approach To Dna Sequencing Employing Near -Ir Fluorescence Detection Coupled With Microscale Reaction Vessels With Capillary Gel Separations., Daryl Clifford Williams

LSU Historical Dissertations and Theses

Electropherograms of oligonucleotides labeled with near-IR fluorescent dyes, separated by capillary gel electrophoresis (CGE) and detected using an ultrasensitive near-IR fluorescence detection system will be presented. A Universal M13 sequencing primer was labeled on the 5' end with a near-IR dye containing an isothiocyanate functional group. Comparison of the on-column detection limits in capillary gel electrophoresis for the near-IR-labeled sequencing primer to that of a visible fluorescein-labeled primer indicated improved sensitivity for the near-IR case. The detection limit was found to be 3.4 x 10-20 moles (SNR = 3) for the near-IR-labeled primer while the on-column detection limit for the …

Executive Compensation And The Investment Opportunity Sets Of Initial Public Offerings., Tanya S. Nowlin Jan 1999

Executive Compensation And The Investment Opportunity Sets Of Initial Public Offerings., Tanya S. Nowlin

LSU Historical Dissertations and Theses

This study examines how the components of CEO compensation contracts vary with characteristics of initial public offering firms (IPOs). There are two major steps in the analysis. The first step investigates whether IPOs exhibit variation in characteristics that theory predicts affect compensation contracts. The second step investigates whether these differences across firms are related to the use of accounting versus non-accounting performance evaluation measures, levels of base salary and cash bonuses, and the value of stock options for CEOs. Results from this study support the importance of modeling compensation components separately. Theoretical constructs differ depending on the type of compensation …

Relating Process Philosophy To The Classroom: An Exploration Of Alfred North Whitehead's Educational Vision., Janis Pardue Hill Jan 1999

Relating Process Philosophy To The Classroom: An Exploration Of Alfred North Whitehead's Educational Vision., Janis Pardue Hill

LSU Historical Dissertations and Theses

This dissertation is an exploration of the connections between the process philosophy and the educational thinking of Alfred North Whitehead. It develops the theory that Whitehead's philosophy of process is evident in "embryonic" form in his earlier educational writings, as well as The Aims of Education and Other Essays (1929), and that the complexities of process thinking are as intertwined and interconnected with the principles of process educational thought as the actual entity is intertwined and interconnected with the complex relations involved in its concrescence. The ultimate aim is to provide a clear picture of Whitehead's vision of education and …

College Students' Understanding Of Stereochemistry: Difficulties In Learning And Critical Junctures., Gary Lester Lyon Jan 1999

College Students' Understanding Of Stereochemistry: Difficulties In Learning And Critical Junctures., Gary Lester Lyon

LSU Historical Dissertations and Theses

Because stereochemistry is an important part of both high school and college chemistry curricula, a study of difficulties experienced by students in the learning of stereochemistry was undertaken in a one-semester college organic chemistry course. This study, conducted over the course of two semesters with more than two hundred students, utilized clinical interviews, concept maps, and student journals to identify these difficulties, which were then tabulated and categorized. Although student journals were not a productive source of information, the types of difficulties that emerged from the concept maps were compared and contrasted with those that emerged from the clinical interviews. …

College Choice: Psychological Factors Influencing *Postsecondary Aspirations And Expectations Of Ninth-Grade Students., Stuart Earle Johnson

LSU Historical Dissertations and Theses

The purpose of this study was to explore relationships between several variables which help to explain the process by which adolescents decide to pursue a college education. Previous models were enhanced by including important theoretical constructs well documented in social cognitive and attributional theories as elements of human agency. The psychological constructs, self-efficacy and locus of control were the primary focus of attention as independent variables and for their significance as mediating variables affecting the relationship between previously identified factors attributed to students' postsecondary attendance decisions, and students' college aspirations and expectations. Particular attention was given to the college choice …

Out Of Sight, Out Of Mind: A Gis Study Of Changes In Cemetery Locations In Southeastern Louisiana From An Archaeological And Geographical Perspective, 1930--1997., Cindy Ann Nance Jan 1999

Out Of Sight, Out Of Mind: A Gis Study Of Changes In Cemetery Locations In Southeastern Louisiana From An Archaeological And Geographical Perspective, 1930--1997., Cindy Ann Nance

LSU Historical Dissertations and Theses

Cemeteries in southeastern Louisiana are in varying stages of use---from presently in use and maintained to no longer visible on the surface. The abandonment of traditional cemeteries in southeastern Louisiana illustrates evolving settlement patterns. Earlier settlement patterns were dependent on physiographic and cultural landscape features. As settlement patterns evolve, the preferred locations of cemeteries change. As a recent participant in the nationwide preference for urban-associated Memorial Parks, is Louisiana in the process of abandoning traditional cemetery landscapes? Six factors that contribute to the abandonment of traditional cemeteries from 1930 to 1997 are presented in this study. Evolving communities, demographic shifts, …

Instantaneous Learning Neural Networks., Kun Won Tang Jan 1999

Instantaneous Learning Neural Networks., Kun Won Tang

LSU Historical Dissertations and Theses

Instantaneous learning is a desirable feature in neural networks. This type of learning enables the network to be trained very quickly, typically in just one or two passes of the training set as opposed to hundreds or even thousands of passes for networks trained by an iterative process, such as the error backpropagation (BP) algorithm. This dissertation first reviews several existing types of neural networks with instantaneous learning capability. It then proposes a new network called the Fuzzy Classification (FC) Neural Network that can be trained with two passes of the training samples. The first pass assigns the synaptic weights …

Multimillion Atom Molecular Dynamics Simulations Of Adhesion And Nanoindentation Of Silicon Nitride., Phillip Judson Walsh Jan 1999

Multimillion Atom Molecular Dynamics Simulations Of Adhesion And Nanoindentation Of Silicon Nitride., Phillip Judson Walsh

LSU Historical Dissertations and Theses

Multi-million atom molecular dynamics (MD) simulations of nanoindentation of silicon nitride and amorphization and fracture of silicon diselenide nanowires are performed on massively parallel architectures. System sizes range from 75,803 atoms to over 10 million atoms. The process of amorphization and fracture in silicon diselenide nanowires is followed using configuration space images in smaller wires and local stress and temperature calculations in larger wires. A structural transformation in the nanowire cross sections is investigated. The nanowires are found to contract in one direction perpendicular to the applied strain while expanding in the other, so that initially circular nanowires are transformed …

Machine -Cell Location Problems For Multiproduct Flowlines., Junfang Yu Jan 1999

Machine -Cell Location Problems For Multiproduct Flowlines., Junfang Yu

LSU Historical Dissertations and Theses

Jobs (parts) and machines are usually grouped into part-families and machine-cells in a flexible, cellular manufacturing system to minimize the flows of all work-in-processes (WIP). As a result of this grouping, some parts may need processing on some machines that are not in their own cells. The parts requiring machines in other cells are called 'exceptional parts,' and the corresponding machines are called ' bottleneck machines.' Usually, there are two ways to deal with this inter-cell flow problem: using a material handling system to move the exceptional parts among the cells or duplicating the bottleneck machine(s) for the corresponding exceptional …

Importance Of Convection And Damping On Rates Of Convergence For The Lax-Wendroff Method, Joseph Kolibal Jan 1999

Importance Of Convection And Damping On Rates Of Convergence For The Lax-Wendroff Method, Joseph Kolibal

Faculty Publications

It is well known that in solving steady state problems using hyperbolic time-stepping methods the intent is to drive the transients to zero as quickly as possible. In this paper the convergence to steady state of the Lax-Wendroff method applied to solving the equations of gas dynamics is analyzed for the Laval nozzle problem by comparing the relative rates of damping and convection using a linearized eigenmode analysis. This analysis is developed for the simpler isenthalpic system and then extended to the full Euler equations. Finally, this allows a comparison between these systems. For both models, useful analytical information can …

Racial And Ethnic Studies, Political Science And Mid-Wifery, Vine Deloria Jr., David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

One of the major fallacies of Western civilization, according to Alfred North Whitehead,' was the propensity of Western thinkers to assume that ideas generated within their intellectual landscape were indicative of reality itself. Although some phases of Western science, notably physics and philosophy, have transcended their parochial origins, aspects of the old medieval synthesis still remain in the Western worldview. The gradual fragmentation of the old categories of natural history and theology into the isolated sciences and disciplines of today has produced a myriad of separate bodies of knowledge complete with their professional priesthoods and has allowed considerable slippage in …

Y51k And Still Counting: Some Hindu Views Of Time, Vasudha Narayanan Jan 1999

Y51k And Still Counting: Some Hindu Views Of Time, Vasudha Narayanan

Journal of Hindu-Christian Studies

At the beginning of every religious ritual conducted in Hindu brahmanical modes, the officiating priest and those doing the ritual formally declare the co-ordinates of the land and the time in which the rite takes place. These words are part of the sankalpa or the declaration of intention to do the ritual. Such co-ordinates are in cosmic frameworks; the land is identified with one of the dvipas or islands in puranic cosmology and the timespan is given as a moment that occurs in a span of millions of years. The celebrant first announces the name of the kalpa (a span …

Investigating The Allosteric Behavior Of Malate Dehydrogenase From Escherichia Coli, Eman M. Ghanem Jan 1999

Investigating The Allosteric Behavior Of Malate Dehydrogenase From Escherichia Coli, Eman M. Ghanem

Masters Theses

Regulatory mechanisms of malate dehydrogenase from E.coli (eMDH) involving NADH as an allosteric effector were investigated. The reaction was studied in both directions: malate oxidation and oxaloacetate reduction. When malate was the variable substrate, a plot of rate against substrate concentration was sigmoidal in the presence of 0.065 mM NADH, which indicates the presence of an allosteric site for NADH on the enzyme. Binding of NADH at the allosteric site causes conformational changes in the active site and, thereby, changes the catalytic activity of the enzyme. An increase in Km value, from 1.3 to 3.9 mM malate was observed, …
