The Effects Of The Tax Reform Act Of 1986 On The Real Estate Capital Markets And Its Differential Effects On Entity And Functional Forms: An Empirical Investigation., Evelyn C. Hume
LSU Historical Dissertations and Theses
Differences of opinion exist in the literature regarding the relationship between changes in tax policy and changes in the value of firms' capital stock. The purpose of this study was twofold. One aim was to determine whether the real estate capital markets react to public information regarding proposed or actual changes in tax law. The second and primary objective was to test the traditional economic theory that a direct relationship exists between changes in tax law and the value of the firm. Changes in cost recovery rules for real property and in corporate tax rates were the tax provisions of …
The Impact Of The Anticipated And Unanticipated Components Of Public Debt On Output., Patricia A. Freeman Knight
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. …
Estimation Of The Renewal Function., Binshan Lin
Estimation Of The Renewal Function., Binshan Lin
LSU Historical Dissertations and Theses
The computation of the renewal function when the distribution function is completely known has received much attention in the literature. However, in many cases the form of the distribution function is unknown and has to be estimated nonparametrically. Several nonparametric estimators for the renewal function for complete data were suggested by Frees (1986) and Schneider et al. (1988). In many cases, however, censoring of the lifetime might occur. In this study, estimators of the renewal function based on randomly censored data is discussed. We introduce nonparametric estimators of the renewal function and show that the estimators compare well with a …
The Historical Geography Of Rice Culture In The American South., Jeon Lee
The Historical Geography Of Rice Culture In The American South., Jeon Lee
LSU Historical Dissertations and Theses
The South Atlantic Hearth was the dominant rice producer during the colonial and antebellum periods. Rice production in the region declined after the outbreak of the Civil War, but the region kept the leading position until the 1880s. Along the Lower Mississippi River in southern Louisiana a remarkable amount of rice was produced from the antebellum period, reaching a peak in the 1890s. A major regional shift occurred when rice culture on a large-scale, commercial basis developed in southwestern Louisiana during the 1880s by transplanted Midwesterners. From there it spread into southeastern Texas during the last decade of the nineteenth …
Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman
Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman
LSU Historical Dissertations and Theses
A study of talented characters reveals that three of the most influential novelists in English dealt with the often disabling image of the artist they had inherited from their Romantic forebears by insisting on dialectical tension between the artist and society as essential to the creation of literary art. The various talented characters in Hawthorne's short fiction, such as Aylmer, Rappaccini, Oberon, the Canterbury poet, the portrait painter of "The Prophetic Pictures," the woodcarver Drowne, and Owen Warland, fail to create art unless they retain certain links with their societies of origin. This tension between artist and society appears as …

The Influence Of Calonectria Crotalariae On Population Development Of Heterodera Glycines On Resistant And Susceptible Soybeans., Charles Overstreet
The Influence Of Calonectria Crotalariae On Population Development Of Heterodera Glycines On Resistant And Susceptible Soybeans., Charles Overstreet
LSU Historical Dissertations and Theses
Calonectria crotalariae enhanced root penetration of Lee 74 (susceptible) and Centennial (resistant) soybeans by juveniles of race 3 of Heterodera glycines. The presence of the fungus resulted in greater numbers of females and both soil and root cysts on Lee 74 during the first 30 days. Greater numbers of soil cysts were recovered from Lee 74 at 80 and 120 days and from Centennial at 120 days after inoculation with both pathogens. Root colonization by the fungus increased from 19% to 57% at 40 days on Lee 74 and from 58% to 86% on Centennial at 120 days in the …
How Forgetting Facilitates Remembering: An Analysis Of The Contextual Interference Effect In Motor Learning., Carol Cosgrove Poto
How Forgetting Facilitates Remembering: An Analysis Of The Contextual Interference Effect In Motor Learning., Carol Cosgrove Poto
LSU Historical Dissertations and Theses
The experiments reported here were designed to test a hypothesis regarding why the contextual interference (CI) effect in retention of motor skills occurs. It was hypothesized that the high-CI or random group performs better on a retention test than the low-CI or blocked group because the random schedule has included practice in retrieving motor tasks from long-term memory (LTM). This is the same information-processing activity required for successful retention test performance. In essence, both groups learn the motor task to the same extent, but the random group also learns to recall the task from LTM on demand. In the first …
The Systematics Of The Genus Thyanta Stal (Hemiptera:Heteroptera:Pentatomidae)., David Allen Rider
The Systematics Of The Genus Thyanta Stal (Hemiptera:Heteroptera:Pentatomidae)., David Allen Rider

The pentatomid genus Thyanta Stal is one of several large genera in the nominate subfamily and tribe. Thyanta belongs among those genera of Pentatomini lacking a spine or tubercle at the base of the third (second visible) abdominal sternite. The genus is divided into two subgenera: Phacidium Breddin, containing a single species, T. aeruginosa Berg; and the nominate subgenus, containing 36 species and one subspecies. The subgenus Thyanta is further divided into four species groups based primarily on differences and similarities in male and female genitalia. The perditor species group contains nine species and one subspecies, the maculata species group …
Statistical Mechanical And Experimental Studies Of Thermodynamic Behaviour Of Aromatic Hydrocarbons., Wahyudi Budi Sediawan
Statistical Mechanical And Experimental Studies Of Thermodynamic Behaviour Of Aromatic Hydrocarbons., Wahyudi Budi Sediawan
LSU Historical Dissertations and Theses
Statistical mechanical studies of aromatic hydrocarbon liquids have been conducted. Aromatic rings are modeled as oblate ellipsoids interacting with a modified gaussian overlap potential. This approach has been tested by molecular dynamics simulations and shown to work well for benzene and naphthalene. Addition of quadrupolar interactions further improves the results. More molecular dynamics simulation data for the gaussian overlap potential, the modified gaussian overlap potential, and a dumbell of the modified gaussian overlap potential have also been generated, to test an existing non-spherical based perturbation theory (Fischer's theory) and a newly introduced sphericalized potential method. Both approximations work qualitatively well …
Studies On The Reactions Of Polycyclic Aromatic Hydrocarbons With Nitrogen-Dioxide In Aprotic Solvents., Giuseppe Luciano Squadrito
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 …
The Dark Side Of Paradise: Race And Ethnicity In The Novels Of F. Scott Fitzgerald., Felipe Smith
The Dark Side Of Paradise: Race And Ethnicity In The Novels Of F. Scott Fitzgerald., Felipe Smith
LSU Historical Dissertations and Theses
According to author and scholar Ralph Ellison, the writers of the early twentieth century (with the exception of Faulkner) adopted Mark Twain's stylistic innovations in pursuit of their personal myth instead of "recreating and extending the national myth" by continuing Twain's development of "the Negro as the symbol of man." To Ellison, these writers had capitulated to a strong current prevalent in American thought: American self-definition in racially exclusive terms. They presented as reality stereotyped portrayals of blacks and other ethnic minorities which served as "key figure (s) in a magic rite by which the white American seeks to resolve …
An Investigation Of The Fungus, Balansia Cyperi Edg., And Its Effect On Purple Nutsedge, Cyperus Rotundus L., Mary Elizabeth Stovall
An Investigation Of The Fungus, Balansia Cyperi Edg., And Its Effect On Purple Nutsedge, Cyperus Rotundus L., Mary Elizabeth Stovall
LSU Historical Dissertations and Theses
This study was designed to investigate host specificity of the fungus Balansia cyperi Edg. on Cyperus rotundus L. (purple nutsedge) and to determine the effect of fungus presence on the biology and ecology of the sedge. Isolates of epiphytic Balansias from C. rotundus and C. virens had similar cultural characters, conidium morphology, and extracellular enzyme activity in artificial culture. However, B. cyperi from C. rotundus had a faster growth rate, greater conidium production, and higher temperature optimum than did the isolate from C. virens. Artificial infection of C. rotundus by B. cyperi from C. rotundus was far more successful than …
Site-Directed Mutagenesis In Fructose 6-Phosphate-1-Kinase From Bacillus Stearothermophilus And Molecular Cloning And Sequencing Of A Partial Human Muscle Fructose 6-Phosphate-1-Kinase Gene., Benigno Calderon Valdez
Site-Directed Mutagenesis In Fructose 6-Phosphate-1-Kinase From Bacillus Stearothermophilus And Molecular Cloning And Sequencing Of A Partial Human Muscle Fructose 6-Phosphate-1-Kinase Gene., Benigno Calderon Valdez
LSU Historical Dissertations and Theses
Fructose 6-phosphate-1-kinase (PFK: EC. 2.7.1.11) catalyzes the phosphorylation of $\beta$-fructose 6-phosphate (Fru 6-P) to $\beta$-fructose 1,6-bisphosphate. The first part of this dissertation shows that PFK from Bacillus stearothermophilus (BsPFK) unlike the major PFK from E. coli (EcPFKA) exhibits a hyperbolic profile with respect to Fru 6-P concentration in the absence of phosphoenolpyruvate (PEP). BsPFK is sensitive to inhibition by high ATP concentrations and competitively inhibited by GDP or ADP. Arg-252 residue of BsPFK has been proposed to be involved in the binding of Fru 6-P. Mutation of this residue to alanine (RA252) increases BsPFK affinity for its inhibitor PEP (a …
An Initial Identification Of Parasite Specific Immune Responses In The Jird (Meriones Unguiculatus) Infected With Brugia Pahangi., Rita Gaskin Farrar
An Initial Identification Of Parasite Specific Immune Responses In The Jird (Meriones Unguiculatus) Infected With Brugia Pahangi., Rita Gaskin Farrar
LSU Historical Dissertations and Theses
Brugia pahangi infections in the jird (Meriones unguiculatus) is an accepted experimental model for the study of human lymphatic filariasis. Initial identification of parasite specific immune responses in jirds infected with B. pahangi are reported here. Antibody reactivity in sera from singly and multiply infected jirds against different stages of B. pahangi was determined using an indirect fluorescent antibody technique. All life cycle stages of the parasite were examined. Antibodies recognizing all stages were present in all serum samples. Removal of antibody reactivity by absorption of jird sera with B. pahangi antigen coated beads indicated that the antibodies were parasite …

Platelet-derived growth factor (PDGF) mRNA, and mRNA for its receptor, have been localized to specific cell types within the human atherosclerotic plaque, using in situ hybridization. The predominant cell types found to express PDGF A and B chain mRNA are mesenchymal-appearing intimal cells and endothelial cells, respectively, with little or no expression detected in macrophages. The distribution of PDGF receptor mRNA containing cells was also examined and found to be localized predominantly in the plaque intima.

The authors discuss the use of CDxs (Cyclodextrins) to enhance selective detection via EEM (Excitation Emission Matrix) measurements. Particular emphasis will be placed on the enhanced measurement of luminophors complexed with CDxs in the presence of select alcohols and quenchers. In addition, the use of solvent extraction and data analysis to reduce the dimensionality of the acquired EEM will be discussed. The use CDxs and quenchers can produce a single- or dual-component system from a more complex mixture, which can then be used as model component spectra. This type of data analysis scheme is presented and discussed. In this study, …

Thermal Properties Of A Series Of Side-Chain Liquid Crystalline Poly(Methacrylates)., R. Duran, D. Guillon, Ph Gramain, A. Skoulios
Faculty Publications
The thermal behavior of a series of side-chain liquid crystalline poly(methacrylates) has been investigated by thermogravimetry, differential scanning calorimetry, polarizing optical microscopy, and dilatometry. The DSC study has shown that long times are required to reach equilibrium even at temperatures above the glass transition. The thermotropic polymorphism has been determined as a function of the length of the flexible spacer. Glass transitions in the mesomorphic state have been discussed. Dilatometry has shown that, for the 'glassy' mesomorphic phases, the partial specific volume of the flexible spacer is close to that corresponding to the crystal and the isotropic liquid; and that, …

Determination Of The Range In Binding-Site Densities Of Rat Skin Heparin Chains With High Binding Affinities For Antithrombin., A. A. Horner, M. Kusche, U. Lindahl, C. B. Peterson
Faculty Publications
Rat skin heparin proteoglycans vary markedly in the proportions of their constituent polysaccharide chains that have high binding affinity for antithrombin. As the proportion of such chains in a proteoglycan rises, their degree of affinity for antithrombin also increases [Horner (1987) Biochem. J. 244, 693-698]. The antithrombin-binding-site densities of such chains have now been determined, by measuring heparin-induced enhancement of the intrinsic fluorescence of antithrombin and by chemical analysis for the disaccharide sequence glucuronosyl-N-sulphoglucosaminyl (3,6-di-O-sulphate), which is unique to this site in heparin [Lindahl, Bäckström, Thunberg & Leder (1980) Proc. Natl. Acad. Sci. U.S.A. 77, 6551-6555]. Antithrombin-binding-site density ranged from …

Divergence Of The Recent Trends In Coronary Mortality For The Four Major Race-Sex Groups In The United States, C. Sempos, R. Cooper, M. G. Kovar, M. Mcmillen
Faculty Publications
Since 1976 there has been a leveling off or slowdown in the rate of decline in coronary heart disease (CHD) mortality. The age-adjusted absolute annual rate of decline in CHD mortality rates during 1968-75 (Δ rate/100,000 population/year) was virtually identical for White males (-7.54), Black males (-7.85), and Black females (-7.20), and somewhat lower for White females (-4.25). During 1976-85, however, the secular trends diverged considerably. Age-adjusted rates continued to decline at the same annual rate for White males, while the decline was approximately half as steep for the other three race-sex groups. During 1976-85 there was also a leveling …

Integrated Semigroups And Their Applications To The Abstract Cauchy Problem, Frank Neubrander
Integrated Semigroups And Their Applications To The Abstract Cauchy Problem, Frank Neubrander
Faculty Publications
This paper is concerned with characterizations of those linear, closed, but not necessarily densely defined operators A on a Banach space E with nonempty resolvent set for which the abstract Cauchy problem u′(t) = Au(t), u(0) = x has unique, exponentially bounded solutions for every initial value x ∈ D(An). Investigating these operators we are led to the class of "integrated semigroups". Among others, this class contains the classes of strongly continuous semigroups and cosine families and the class of exponentially bounded distribution semigroups. The given characterizations of the generators of these integrated semigroups unify and generalize the classical characterizations …

A Community Sample's Knowledge Of, Judgment Of, And Attitudes Toward Childrearing And Child Abuse., Harriet Schoenberg Williams
LSU Historical Dissertations and Theses
The present study addressed an important void in the literature of child abuse prevention. The challenge in empirical development of preventive education in child abuse to the public lies in the identification of specific target behaviors which are (1) related to potential child abuse, and (2) amenable to education. This investigation examined individual's expectations, attitudes and beliefs toward childrearing, as well as individual's knowledge of childrearing and behavioral child management techniques. Data generated in this study also evaluated the presence of differential judgments of child abuse in a community sample. Two hundred and eighty-two community volunteers participated in this study. …
