Three Essays On The Determinants And Effects Of Public Sector Bargaining Laws., Melissa S. Waters Jan 1989

Three Essays On The Determinants And Effects Of Public Sector Bargaining Laws., Melissa S. Waters

LSU Historical Dissertations and Theses

The theoretical foundation of this model is the economic theory of regulation as developed by Stigler; in addition, modifications of the economic or special interest theory implied by the Public Choice school of thought are employed. A synthesis of these two theories of regulation, then, provides the framework upon which to develop a general model of the causes and consequences of laws regulating the bargaining rights of state employees. Topic One is devoted exclusively to the determinants of state-wide bargaining rights laws. The data are pooled over two years, and state laws are classified into one of three possible categories: …

Essays On The Components Of The Bid-Ask Spread., Pei-Hwang Wei Jan 1989

Essays On The Components Of The Bid-Ask Spread., Pei-Hwang Wei

LSU Historical Dissertations and Theses

The presence of the bid-ask spread causes equilibrium prices to deviate from transaction prices. More importantly, the components of the spread--the order component, the inventory component, and the information component--have different impacts on transaction prices. In general, the order and the inventory components induce negative correlation in successive transaction price changes. On the other hand, transaction prices will form a martingale if only the information component exists. This dissertation is composed of three related essays that utilize this general relationship between transaction prices and the components of the spread. The first essay employs a cross-sectional analysis that relates components of …

Pro Bono Publico: New Orleans Politics And Municipal Reform In The Progressive Era, 1912-1926. (Volumes I And Ii)., Terrence Walter Fitzmorris Jan 1989

Pro Bono Publico: New Orleans Politics And Municipal Reform In The Progressive Era, 1912-1926. (Volumes I And Ii)., Terrence Walter Fitzmorris

LSU Historical Dissertations and Theses

Social prejudice and moral consideration did not form the basis of city politics and municipal reform in New Orleans during the Progressive Era. The Regular Democratic Organization, the so-called political machine and the civic reformers of New Orleans were more concerned with issues of expanding and centralized municipal authority, regulation of private and public corporations, completion and expansion of public services, "living wages" and decent working conditions for organized labor, equitable taxation and assessment rates for property holders, and city planning and development. Admittedly, the principal leadership of the municipal reform movement came from the "upper crust" of New Orleans …

Non-Newtonian Fluid Flow In Eccentric Annuli And Its Application To Petroleum Engineering Problems., Mustafa Haciislamoglu Jan 1989

Non-Newtonian Fluid Flow In Eccentric Annuli And Its Application To Petroleum Engineering Problems., Mustafa Haciislamoglu

LSU Historical Dissertations and Theses

The fluid flow in the annular gap in oilwells is a complex problem. The geometry of the annulus is customarily simplified to concentric annular flow. In this study, a fluid flow model is developed allowing annulus to be eccentric: inner pipe located anywhere in the annulus. Thus, a more realistic representation of the actual geometry is obtained. An equation of motion that defines flow of non-Newtonian fluids in eccentric annuli is derived. A numerical solution of this equation is presented. The velocity profiles, the viscosity profiles, and the flow rate vs frictional pressure loss gradient relationship are calculated for varying …

A Density-Based General Greedy Channel Routing Algorithm In Vlsi Design Automation., Tai-Tsung Ho Jan 1989

A Density-Based General Greedy Channel Routing Algorithm In Vlsi Design Automation., Tai-Tsung Ho

LSU Historical Dissertations and Theses

One of the most important forms of routing strategies is called "channel routing". This approach allows us to reduce the extremely difficult VLSI layout problem to a collection of simpler subproblems. For channel routing problems, most frequently mentioned heuristic algorithms use parameters derived from experiments to approach the routing solution without carefully considering the effect of each selected wire segment to the final routing solution. In this dissertation, we propose a new channel routing algorithm in the two-layer restricted-Manhattan routing model (2-RM) in detail. There are three phases involved in developing the new routing algorithm. In the first phase, we …

Optimal Design And Control Of Distribution System Capacitors., Nugroho Iwan Santoso Jan 1989

Optimal Design And Control Of Distribution System Capacitors., Nugroho Iwan Santoso

LSU Historical Dissertations and Theses

The rapidly escalating costs of generation and transmission facilities as well as energy production have focussed attention on the need to optimize system capacity release and energy losses. The problem is generally solved by controlling the voltage or reactive power which also has a pivotal role within the distribution automatization schemes. A review of reactive power compensators and methodologies in designing and controlling distribution capacitors is given. In the presence of voltage source harmonics, a local load reactive power compensation method, cost-constrained power factor optimization using an LC compensator, is discussed. A new methodology based on a piecewise method for …

Model-Based Three-Dimensional Object Recognition And Localization Using Properties Of Surface Curvatures., Wu Wang Jan 1989

Model-Based Three-Dimensional Object Recognition And Localization Using Properties Of Surface Curvatures., Wu Wang

LSU Historical Dissertations and Theses

The ability to recognize three-dimensional (3-D) objects accurately from range images is a fundamental goal of vision in robotics. This facility is important in automated manufacturing environments in industry. In contrast to the extensive work done in computer-aided design and manufacturing (CAD/CAM), the robotic process is primitive and ad hoc. This thesis defines and investigates a fundamental problem in robot vision systems: recognizing and localizing multiple free-form 3-D objects in range images. An effective and efficient approach is developed and implemented as a system Free-form Object Recognition and Localization (FORL). The technique used for surface characterization is surface curvatures derived …

Models And Tests In Functional Morphology: The Significance Of Description And Integration, Dominique G. Homberger Dec 1988

Models And Tests In Functional Morphology: The Significance Of Description And Integration, Dominique G. Homberger

Faculty Publications

SYNOPSIS: Functional-anatomical work on complex structural systems is handicapped by several difficulties: (1) Lack of established guidelines on how to select the structures that are relevant for the intended study, (2) lack of methods to check the accuracy of the description of a system's morphology, and (3) the need to integrate a large mass of results obtained through a variety of approaches taken from different disciplines, such as anatomy, physiology, physics, biochemistry, ecology and evolutionary biology. Suggestions to alleviate some of the problems include (1) to use information on the physiological and physical properties of the tissues in a system …

The UNISOR on-line nuclear orientation facility (UNISOR/NOF) consists of a3He-4He dilution refrigerator on line to the isotope separator. Nuclei are implanted directly into a target foil which is soldered to the bottom accessed cold finger of the refrigerator. A 1.5 T superconducting magnet polarizes the ferromagnetic target foils and determines the axis of symmetry. Up to eight gamma detectors can be positioned around the refrigerator, each 9 cm from the target. A unique feature of this system is that the k=4 term in the directional distribution function can be directly and unambigously deduced so that a single solution for the …

Independent Oscillator Model Of A Heat Bath: Exact Diagonalization Of The Hamiltonian, G. W. Ford, J. T. Lewis, R. F. O'Connell Oct 1988

Independent Oscillator Model Of A Heat Bath: Exact Diagonalization Of The Hamiltonian, G. W. Ford, J. T. Lewis, R. F. O'Connell

Faculty Publications

The problem of a quantum oscillator coupled to an independent-oscillator model of a heat bath is discussed. The transformation to normal coordinates is explicitly constructed using the method of Ullersma. With this transformation an alternative derivation of an exact formula for the oscillator free energy is constructed. The various contributions to the oscillator energy are calculated, with the aim of further understanding this formula. Finally, the limitations of linear coupling models, such as that used by Ullersma, are discussed in the form of some critical remarks. © 1988 Plenum Publishing Corporation.

The Systematics Of Nerodia Clarkii And Nerodia Fasciata, Patrick Allan Myer May 1988

The Systematics Of Nerodia Clarkii And Nerodia Fasciata, Patrick Allan Myer

LSU Historical Dissertations and Theses

The systematic relationship between the Gulf saltmarsh snake, Nerodia fasciata clarkii. and the freshwater subspecies, N. f. confluens. N. f. fasciata, and N. f. pictiventris, is re—evaluated using morphological characters that reflect head shape. Changes in character-states are analyzed from areas of contact into the populations of the freshwater forms. Beyond the narrow zones where intermediates are found there is no morphological evidence suggesting genetic introgression of clarkii genes into the freshwater populations. Discriminant analysis of the head scale measurements also suggests the significant division of the saltmarsh and freshwater forms. Ecological analysis reveals that interbreeding between the forms is …

A Behavioral Test Of The Affinity-Seeking Model: Nonverbal Tactics Among Strangers And Acquaintances., Dominique Marie Gendrin Jan 1988

A Behavioral Test Of The Affinity-Seeking Model: Nonverbal Tactics Among Strangers And Acquaintances., Dominique Marie Gendrin

LSU Historical Dissertations and Theses

This research examined the Affinity-Seeking model devised by Bell and Daly (1984). Two components of the model were considered: preinteraction expectancies constraining a social encounter and the competency of the individual as an affinity-seeker. It was hypothesized that strangers would approach a friendly target through the reciprocity strategy and an unfriendly target through the compensatory strategy by increasing behavioral cues of immediacy (e.g., eye-gaze, smiling/laughter, verbalizations, and proximity). It was hypothesized, on the other hand, that acquaintances would not increase their behavioral involvement in view of a friendly expectancy while they would compensate for an unfriendly one. The findings revealed …

The Impact Of The Anticipated And Unanticipated Components Of Public Debt On Output., Patricia A. Freeman Knight Jan 1988

The Impact Of The Anticipated And Unanticipated Components Of Public Debt On Output., Patricia A. Freeman Knight

LSU Historical Dissertations and Theses

This dissertation examines the impact of the anticipated and unanticipated components of government debt on real output when Barro's equations for debt growth and money growth are used as the starting points in specifying anticipated debt and money growth equations using an atheoretical statistical technique. The unanticipated debt and money variables are defined as the residual of the anticipated debt and money growth equations, respectively. Output equations are specified using the same criteria that are used to specify the anticipated debt and money growth equations, and Barro's equation for real GNP is used as the starting point in the specification. …

The Time Course Of Acoustic/Phonemic Cue Integration In The Sensorineural Hearing-Impaired., Donald Joseph Schum Jan 1988

The Time Course Of Acoustic/Phonemic Cue Integration In The Sensorineural Hearing-Impaired., Donald Joseph Schum

LSU Historical Dissertations and Theses

It has been documented that phonemic featural information is differentially distributed across time in the speech waveform. It is also known that listeners with sensorineural hearing impairment often make errors on phoneme identification tasks. However, there is little documentation available that describes how the hearing-impaired listener uses the various sources of phonemic information which are distributed in the speech waveform. In this investigation, a group of normal hearing listeners and a group of sensorineural hearing-impaired listeners (with and without the benefit of amplification) identified various consonant and vowel productions that had been systematically varied in duration. The consonants (presented in …

Star Formation, Using Three-Dimensional Explicit Eulerian Hydrodynamics., Harold Alden Williams Jan 1988

Star Formation, Using Three-Dimensional Explicit Eulerian Hydrodynamics., Harold Alden Williams

LSU Historical Dissertations and Theses

Evolutions of rapidly rotating, self-gravitating objects initially in axisymmetric equilibrium have been studied using a 3-D Newtonian hydrodynamic computer code with an eye toward understanding angular momentum transport in dynamically evolving protostars. First, a number of evolutions have been modeled using an existing explicit, Eulerian, finite difference code that is accurate to first-order in its spatial differences. The bar-mode dynamic instability has been explored by considering several models with different degrees of compressibility. This instability occurs in models having $\beta > \beta\sb{d} \equiv$ 0.27, where $\beta$ is the ratio of the rotational to the gravitational potential energy. A two-armed spiral, with …

Stein-Like Estimation And Inference., Lee Chester Adkins Jan 1988

Stein-Like Estimation And Inference., Lee Chester Adkins

LSU Historical Dissertations and Theses

The dissertation addresses three issues in the use of Stein-like estimators of the classical normal linear regression model. The St. Louis equation is used to generate out-of-sample forecasts using least squares. These forecasts are compared to those produced by restricted least squares, pretest, and members of a general family of minimax shrinkage estimators using the root-mean-square error criterion. Bootstrap confidence intervals and ellipsoids are constructed which are centered at least squares and James-Stein estimators and their coverage probability and size is explored in a Monte Carlo experiment. A Stein-like estimator of the probit regression model is suggested and its quadratic …

The Relation Of Teacher Feedback To Student Achievement In Learning Selected Tennis Skills., Tony Eghan Jan 1988

The Relation Of Teacher Feedback To Student Achievement In Learning Selected Tennis Skills., Tony Eghan

LSU Historical Dissertations and Theses

This study assessed the impact of teacher feedback on student achievement in learning three tennis skills (forehand, backhand, and the serve). It also described teacher feedback patterns in teaching beginning tennis. Subjects consisted of a professional tennis instructor and 40 undergraduate male and female students enrolled in two beginning tennis classes. Fifteen 30-min instructional sessions were videotaped and audiotaped within a 10-week period. Subjects were pretested and posttested on the three tennis skills. The tapes were coded for type and frequency of teacher feedback. The mean occurrence of teacher feedback directed to individual students was about 1 (M = 1.4, …

Soil Sorption And Plant Uptake Of 2,4,6-Trinitrotoluene., Judith Carol Pennington Jan 1988

Soil Sorption And Plant Uptake Of 2,4,6-Trinitrotoluene., Judith Carol Pennington

LSU Historical Dissertations and Theses

Potential environmental hazards are posed by the presence of 2,4,6-Trinitrotoluene (TNT) contamination in soils of US Army Ammunition Plants (AAPs). Adsorption and desorption studies were conducted on soil samples collected from 13 AAPs. Soils were found to be primarily silt loams, low in organic carbon. TNT reached a steady state of adsorption with test soils within 2 hrs of contact. Desorption also reached steady state within 2 hrs with more than half of the adsorbed TNT being removed. Batch adsorption isotherms were best fit by the Langmuir adsorption model. Average adsorption coefficients (soil concentration to solution concentration), or K$\sb{\rm d}$, …

An Algorithmic Framework For Robot Navigation In Unknown Terrains., Nageswara S. V Rao Jan 1988

An Algorithmic Framework For Robot Navigation In Unknown Terrains., Nageswara S. V Rao

LSU Historical Dissertations and Theses

The problem of navigating a robot body through a terrain whose model is a priori known is well-solved problem in many cases. Comparatively, a lesser number of research results have been reported about the navigation problem in unknown terrains i.e., the terrains whose model are not a priori known. The focus of our work is to obtain an algorithmic framework that yields algorithms to solve certain navigational problems in unknown terrains. We consider a finite-sized two-dimensional terrain populated by a finite set of obstacles $O$ = $\{O\sb1,O\sb2,\...,O\sb{n}\}$ where $O\sb{i}$ is a simple polygon with a finite number of vertices. Consider …

Intensional Query Processing In Deductive Database Systems., Il Yeol Song Jan 1988

Intensional Query Processing In Deductive Database Systems., Il Yeol Song

LSU Historical Dissertations and Theses

This dissertation addresses the problem of deriving a set of non-ground first-order logic formulas (intensional answers), as an answer set to a given query, rather than a set of facts (extensional answers), in deductive database (DDB) systems based on non-recursive Horn clauses. A strategy in previous work in this area is to use resolution to derive intensional answers. It leaves however, several important problems. Some of them are: no specific resolution strategy is given; no specific methodologies to formalize the meaningful intensional answers are given; no solution is given to handle large facts in extensional databases (EDB); and no strategy …

Neural Networks With Asynchronous Control., Michael Christopher Stinson Jan 1988

Neural Networks With Asynchronous Control., Michael Christopher Stinson

LSU Historical Dissertations and Theses

Neural network studies have previously focused on monolithic structures. The brain has a bicameral nature, however, and so it is natural to expect that bicameral structures will perform better. This dissertation offers an approach to the development of such bicameral structures. The companion neural structure takes advantage of the global and subset characteristics of the stored memories. Specifically we propose the use of an asynchronous controller C that implies the following update of a probe vector x by the connection matrix T: $x\sp\prime$ = sgn (C(x, TX)). For a VLSI-implemented neural network the controller block can be easily placed in …

Online Detection And Estimation Of Parameter Jumps., Fahmida Nilufar Chowdhury Jan 1988

Online Detection And Estimation Of Parameter Jumps., Fahmida Nilufar Chowdhury

LSU Historical Dissertations and Theses

In many dynamic systems, the parameters are subject to jumps at unknown points in time. The jumps may be the result of some change in the operating system, or plant failure. In this work a method has been developed for fast detection of these jumps and estimation of the post-jump values. The proposed method is called the Combined Filter Algorithm. It is based on the conventional Kalman filter. Single-sample hypothesis test is used to determine the presence or absence of jumps. Small jumps, missed by the hypothesis test, are traced by a Random Walk Model Kalman filter. This is made …

Studies On The Reactions Of Polycyclic Aromatic Hydrocarbons With Nitrogen-Dioxide In Aprotic Solvents., Giuseppe Luciano Squadrito Jan 1988

Studies On The Reactions Of Polycyclic Aromatic Hydrocarbons With Nitrogen-Dioxide In Aprotic Solvents., Giuseppe Luciano Squadrito

LSU Historical Dissertations and Theses

There is recent evidence that free radical nitration reactions occur in polluted urban air, and that the nitrated polycyclic aromatic hydrocarbons (NO$\sb2$-PAH) produced by this reaction pathway account for a substantial amount of the total NO$\sb2$-PAH found in ambient particulate organic matter. The nitration of PAH with nitrogen dioxide in solvents of low polarity has been studied as a model for the reactions occurring in the atmosphere (gas phase). While vast amounts of data are available for the electrophilic ionic nitration and its mechanism of reaction is considered well-established (and often included in sophomore Chemistry books), the literature documents relatively …

Amino Acid Responses Of Olfactory Bulb Cells In The Channel Catfish., Hilary Winfield Thompson Jan 1988

Amino Acid Responses Of Olfactory Bulb Cells In The Channel Catfish., Hilary Winfield Thompson

LSU Historical Dissertations and Theses

Amino acid (AA) responses of olfactory bulb (OB) mitral cells (MC) in the catfish, Ictalurus punctatus, were studied electrophysiologically. A total of 63 cells were recorded in 28 fish in two separate experiments. For the first study, 27 cells in 22 fish were studied with olfactory tract (OT) intact during stimulation with 10$\sp{-6}$ M to 10$\sp{-2}$ M concentrations of 11 AA. MC responses were quantified by interspike interval (ISI) variables sensitive to inhibition (maximum ISI) and excitation (number of action potentials (AP), minimum ISI). APs were also counted in subdivisions to produce a measure sensitive to MC response temporal patterning. …

A Comparison And Application Of Select Teaching Methods For The Flute By Henri Alt\`Es, Paul Taffanel - Philippe Gaubert, Marcel Moyse, And Trevor Wye., David Eugene Etienne Jan 1988

A Comparison And Application Of Select Teaching Methods For The Flute By Henri Alt\`Es, Paul Taffanel - Philippe Gaubert, Marcel Moyse, And Trevor Wye., David Eugene Etienne

LSU Historical Dissertations and Theses

Since c.1860, the Paris Conservatoire has employed a succession of master artist/teachers of the silver Boehm flute. This tradition is so distinctive that the term "French Flute School" is used to refer to flute teachers and pupils of the Paris Conservatoire. Certain exponents of the French Flute School have written classic method books which have remained important to Boehm flute players throughout the world. The style and quality of flute literature changed significantly from the mid-nineteenth century to the present and when musical style changed so did demands on the performer. Although studies and exercises are not intended for public …
