Fluorescence Accompanying Photoionization In Polyatomic Molecules And The Relationship To Photoelectron Motion: A Global View., Jiahui Wu Jan 1996

Fluorescence Accompanying Photoionization In Polyatomic Molecules And The Relationship To Photoelectron Motion: A Global View., Jiahui Wu

LSU Historical Dissertations and Theses

Measurements of dispersed fluorescence from electronically excited photoions are used to study fundamental molecular scattering phenomena. Our experimental advances make it possible to obtain vibrationally resolved data that offer qualitative insights into photoionization dynamics in polyatomics. In particular, vibrationally resolved data are measured to probe the correlation of electronic and nuclear degrees of freedom via studying the vibrational distributions of photoions and ionic fragments. Vibrational branching ratios are mapped out over an extremely broad energy range ($\rm3\leq E\sb{k}\leq 200 eV$) for N$\sb2$O (7$\sigma\sp{-1}$) ionization channel. The origin of the non-Franck-Condon behavior is tentatively interpreted as shape resonances and Cooper minima. …

The Association Between Chronic Aerobic Activity And Heart Rate Variability In Patients With Coronary Artery Disease., Robert Howard Wood Jan 1996

The Association Between Chronic Aerobic Activity And Heart Rate Variability In Patients With Coronary Artery Disease., Robert Howard Wood

LSU Historical Dissertations and Theses

Poor heart rate variability (HRV) among patients with coronary artery disease (CAD) is predictive of future incidence of sudden arrhythmic and all-cause death. Furthermore, mental stress appears to further depress HRV in these patients. Chronic aerobic activity level appears to be positively related to HRV among the general population; however, the extent to which this relationship exists among patients with CAD is not clear. Therefore, this study investigated the association between level of chronic aerobic activity and HRV among CAD patients during conditions of paced respiratory control and during the Stroop Color-Word Conflict Test (CWCT). CAD patients were assigned to …

The Alteration Of Komatiitic And Basaltic Rocks From The Barberton Greenstone Belt, South Africa., Xiaogang Xie Jan 1996

The Alteration Of Komatiitic And Basaltic Rocks From The Barberton Greenstone Belt, South Africa., Xiaogang Xie

LSU Historical Dissertations and Theses

Presented are three papers on the aspects of crystal chemistry, structure, and formation conditions of IIb trioctahedral chlorite and actinolite (tremolite) of low-grade metamorphism and metasomatism in the Archean Barberton greenstone belt. A fourth paper reports the pressure effect on the Na-K geothermometer, which results from the study of fluid-rock interaction during low temperature geological processes. The chemical compositions of the two Fe-Mg minerals show strong associations with the MgO$\sb{\rm Rock}$ because MgO$\sb{\rm Rock}$ was the least available stoichiometric component during the crystallization of the minerals. All major cation abundances in both minerals are strongly correlated with each other. A …

Microsatellite-Based Paternity Analysis In Hexaploid Sweetpotato (Ipomoea Batatas (L.) Lam.)., Mario Ignacio Buteler Jan 1996

Microsatellite-Based Paternity Analysis In Hexaploid Sweetpotato (Ipomoea Batatas (L.) Lam.)., Mario Ignacio Buteler

LSU Historical Dissertations and Theses

The use of genetic markers for paternity identification was investigated in hexaploid sweetpotato. Traditional sweetpotato breeding relies on the open pollination of numerous parents and the visual selection of progeny. Previous empirical and theoretical evidence shows this type of breeding system is extremely inefficient. Typically, only a few of these maternal parents routinely produce superior progeny. A similar scenario exists for the paternal parent. Identifying specific parental combinations which produce superior progeny would improve breeding efficiency, hence the need to identify paternity in superior progeny. A computer simulation study established the minimum number of alleles and loci required for paternity …

Bureaucrats, Bureaucracy And Utility Maximization: Empirical Evidence From Taiwan., Chinkun Chang Jan 1996

Bureaucrats, Bureaucracy And Utility Maximization: Empirical Evidence From Taiwan., Chinkun Chang

LSU Historical Dissertations and Theses

An important issue in public finance is concerned with finding an appropriate choice-theoretic model for explaining state and local government fiscal behavior. Economists have traditionally viewed state and local expenditure and tax decision-making processes "as if" they were the results of utility maximization subject to a budget constraint. This approach provides a convenient device for applying the neoclassical demand theory to state and local public sector fiscal behavior. The appropriateness of making such an assumption has, however, not been directly addressed in the literature. This research fills the gap by empirically testing whether the assumption of utility maximization holds in …

Movements, Habitat Use, And Survival Of Female Northern Pintails In Southwestern Louisiana., Robert Ripley Cox Jr Jan 1996

Movements, Habitat Use, And Survival Of Female Northern Pintails In Southwestern Louisiana., Robert Ripley Cox Jr

LSU Historical Dissertations and Theses

I developed portable platforms for setting rocket nets in open-water habitats, and used them to capture 1116 waterfowl of 7 species during winters 1991-92 and 1992-93 in southwestern Louisiana. Distance and duration of evening flights of female northern pintails (Anas acuta; hereafter pintails) from Lacassine National Wildlife Refuge increased with date within wintering period, and generally were greater than previously reported estimates for wintering waterfowl. I found that diurnal use of refuges by females increased during hunting seasons, contradicting Tamisier's hypothesis that use of refuges by pintails in southwestern Louisiana is not influenced by hunting. Female pintails extensively used privately …

An Analysis Of Witold Lutoslawski's "Variations On A Theme By Paganini" For Two Pianos And An Original Composition "Concerto For Two Pianos And Orchestra"., Ling Chao Chen Jan 1996

An Analysis Of Witold Lutoslawski's "Variations On A Theme By Paganini" For Two Pianos And An Original Composition "Concerto For Two Pianos And Orchestra"., Ling Chao Chen

LSU Historical Dissertations and Theses

The dissertation is divided into two parts. Part I is an analysis of Witold Lutoslawski's "Variations on a Theme by Paganini" for Two Pianos. This consists of a detailed analysis preceded by a brief introductory discussion of Witold Lutoslawski's life and musical background. The composer has followed Paganini's model faithfully as far as the basic thematic material is concerned. However, his addition of supporting harmonies, imitative and free countermelodies, and rhythmical accompaniments make this setting an original composition. This analysis focuses on harmony, dynamics, counterpoint, rhythm, form and general texture of the piece. The main issues to be discussed are …

Molecular Systematics Of Red Algae., Jeffrey Craig Bailey Jan 1996

Molecular Systematics Of Red Algae., Jeffrey Craig Bailey

LSU Historical Dissertations and Theses

Phylogenetic analyses of nucleotide sequences for the nuclear-encoded small subunit ribosomal RNA (SSU) gene were used to test current hypotheses of relationships within the Corallinales and among the florideophycidaean orders of red algae. Analyses of SSU gene sequences indicate that the order Corallinales includes four major lineages. The Sporolithaceae is resolved as the earliest-diverging lineage within the order and forms the sister group to a monophyletic Corallinaceae. The molecular data also support the monophyly of the subfamilies Melobesioideae and Corallinoideae. The latter subfamily is inferred as sister to a fourth lineage including non-geniculate and geniculate species classified in the subfamilies …

Women Who Lead High Schools: A Missing Element In Leadership Theory., Kristy Brock Hebert Jan 1996

Women Who Lead High Schools: A Missing Element In Leadership Theory., Kristy Brock Hebert

LSU Historical Dissertations and Theses

I addressed the problem that leadership theory is lacking in regard to how women lead high schools. My primary purpose was to contribute to the limited literature that exists regarding the leadership practices of women who are high school principals. I explored the notion of a female culture of school leadership and situated that culture among quintessential theory dictated by organizational research. I conducted this study in two phases. In Phase One I reported the demographics of 44 female high school principals in Louisiana along with their self-reported values on 32 leadership characteristics. Most important to their leadership were: communication, …

Role Of Hurricane Disturbance In The Dynamics Of The Southern Mixed Hardwood Forest: A Case Study In Northern Florida., William Bennett Batista Jan 1996

Role Of Hurricane Disturbance In The Dynamics Of The Southern Mixed Hardwood Forest: A Case Study In Northern Florida., William Bennett Batista

LSU Historical Dissertations and Theses

The objective of this dissertation was to characterize the role of hurricanes in the dynamics of old-growth Southern Mixed Hardwood Forests from the coastal plain of the northern Gulf of Mexico. First, we used data from five stands to describe the structure, composition, and disturbance regime of these forests. All five stands have Magnolia grandiflora and Fagus grandifolia among the dominant species, and have been affected by frequent but relatively mild hurricanes (4-6 per century, windspeed $<$200 km/h). Second, we examined the changes in tree recruitment, growth, and mortality occurred in Woodyard Hammock, northern Florida, after this forest was affected by Hurricane Kate in 1985. The analysis was based on data from biennial censuses of a 4.5 ha plot conducted between 1978 and 1992. Hurricane Kate produced extensive canopy disruption but limited tree mortality. This disturbance prompted a phase of increased recruitment, growth, and survival of understory trees, and decreased growth and survival of overstory trees. Release of small understory individuals appeared to be critical for the persistence of three short-lived dominant species, Pinus glabra, Ostrya virginiana and Carpinus caroliniana. However, persistence of the longer-lived dominants Magnolia grandiflora, Fagus grandifolia, Liguidambar styraciflua, Nyssa sylvatica, and Ilex opaca, appeared to depend primarily on resistance to hurricane damage. Third, we used matrix population models to test specific hypotheses about mechanisms of persistence of F. grandifolia in Woodyard Hammock. These models showed that, both before and after Hurricane Kate, this population was close to equilibrium. This result supported the hypothesis that persistence of F. grandifolia has resulted from hurricane resistance. Sensitivity analyses of the models suggested that the key for hurricane resistance has been the high survival of medium-size trees. Life-history strategies involving resistance and survival to hurricane disturbance, rather than release and rapid growth, appear to have been prevalent in these forests. However, the hurricane regime would have resulted in coexistence of species with the two types of strategy. Hurricanes would have been frequent enough to secure the persistence of species dependent on release, and mild enough not to compromise that of species dependent on resistance.

The Moderating Effect Of Combinations Of Dissimilar Shoppers' And Sellers' Ethnicities On A Model Of Dyadic Sales Encounters: Shoppers' Perceptions Of Ethnically Different Retail Salespersons., Andrew D. Banasiewicz Jan 1996

The Moderating Effect Of Combinations Of Dissimilar Shoppers' And Sellers' Ethnicities On A Model Of Dyadic Sales Encounters: Shoppers' Perceptions Of Ethnically Different Retail Salespersons., Andrew D. Banasiewicz

LSU Historical Dissertations and Theses

An empirical assessment of the moderating effect of combinations of ethnically dissimilar shoppers and sellers on the nature of retail sales encounters is undertaken. Following the similarity-attraction paradigm (Bochner 1982; Byrne 1961), it is theorized that ethnically similar shoppers and sellers are more attracted to each other than ethnically dissimilar ones, resulting in shoppers' perceptions of sellers' behaviors and personality traits being adversely effected. Operationally, the entire model of sales encounters is moderated by combinations of ethnically dissimilar shoppers and sellers (global moderation hypothesis), or dyadic ethnic dissimilarity. A 2 x 2 experimental design is employed, with the levels of …

Immobilization Of P. Digitatum And Bioconversion Of Limonene To Alpha-Terpineol., Qiang Tan Jan 1996

Immobilization Of P. Digitatum And Bioconversion Of Limonene To Alpha-Terpineol., Qiang Tan

LSU Historical Dissertations and Theses

The parameters of bioconversion of limonene to $\alpha$-terpineol by Penicillium digitatum were determined. This bioconversion was carried out stereo-specifically and selectively by this fungus. (R)-(+)-limonene was selectively converted to (R)-(+)-$\alpha$-terpineol by mycelia of this fungus during early growth phase. Immobilization of the fungal mycelia for use in continuous production of this product was possible. Aeration was critical to this bioconversion. The optimum aeration was about 1.6 mg/L for growing cells and immobilized cells. Substrate inhibition of the bioconversion was not observed when the substrate concentration was below 4% (v/v). End product inhibition was observed. The $\rm Ki\sb{app}$ was 12.08 mM. …

Reduction And Management Of Vibrio Vulnificus In Gulf Coast Oyster (Crassostrea Virginica)., Yu-Pin Chen Jan 1996

Reduction And Management Of Vibrio Vulnificus In Gulf Coast Oyster (Crassostrea Virginica)., Yu-Pin Chen

LSU Historical Dissertations and Theses

The AmeriPure Process (AmeriPure Oyster Company, New Orleans, Louisiana), which is a mild heat treatment for a specific time period, proved effective in eliminating Vibrio vulnificus from the Gulf Coast oysters (Crassostrea virginica), thus reducing the risk of possible V. vulnificus infections. The treatment was effective in the reduction of V. vulnificus in both $1.5\times10\sp5$ MPN/g (high artificially contaminated level) and $2.4\times10\sp3$ MPN/g (low artificially contaminated level) to undetectable level (MPN $<$ 3/g). The mild heat treatment also reduced naturally occurring V. vulnificus $(8.9\pm3.7\times10\sp4$ MPN/g) present in shellstock oysters harvested in warmer months to undetectable levels. The D value for V. vulnificus present in shellstock oyster averaged 45.6 $\pm$ 3.3 seconds at the AmeriPure Process temperature. Mild heat treatment can also control aerobic plate count numbers during refrigerated storage (0-2$\sp\circ$C) and extend the shelf-life of raw oysters for at least 7 days over unprocessed samples. Mild heat treated oysters need to be refrigerated (${<}4\sp\circ$C) to ensure the safety and quality, as well as shelf-life. Oysters treated according to the AmeriPure Process when exposed to an average room temperature of 27$\sp\circ$C were found unacceptable after 24 hours due to the high number of aerobic plate count (10$\sp7$ CFU/g) and were considered not safe to eat. Although there was a slight lightening in color, sensory panels, composed of both traditional raw oyster consumers and infrequent consumers, found the treated product to be comparable in flavor, texture and smell to untreated oysters. According to the result of sensory evaluation, the good oyster flavor of treated samples increased and the off-flavor and off-odor of the treated oysters were significantly lower than the control samples after 7 days of storage on ice. Possible temperature variations, which could occur during the transportation and storage were studied in a temperature abuse study. The result showed that no Vibrio vulnificus was recovered and no significant microbiological quality change was observed after 10 hours of exposure to the room temperature of $22\pm2\sp\circ$C.

Synthesis Of Novel Amino Acids With Incorporation Into Peptides And Synthesis Of Peptides With Novel Aggregation States., Scott Michael Cowell Jan 1996

Synthesis Of Novel Amino Acids With Incorporation Into Peptides And Synthesis Of Peptides With Novel Aggregation States., Scott Michael Cowell

LSU Historical Dissertations and Theses

Peptides exhibit properties based on the amino acids present in the peptide and structure the peptide assumes in its environment. For example, peptides have been shown to be antimicrobial when they are amphipathic and in an $\alpha$-helical shape. The mechanism for this antimicrobial activity is subject to dispute. One theory states that the peptides work by forming a "pore" through the cell membrane which causes a depolarization of the membrane and the cell lysis because of osmosis. Another theory states that the peptides merely compromise the integrity of the membrane by solubilizing the membrane. In order for the "pore" theory …

Genetic Components Of (Co)Variance For Postweaning Growth, Carcass Composition And Meat Quality Traits Among Brahman-Influenced Beef Steers., D. H. Denny Crews Jr

LSU Historical Dissertations and Theses

A genetic analysis was conducted on preweaning and postweaning growth and carcass composition records from steers produced in two long-term crossbreeding studies. In phase I, Angus (A), Brahman (B), Brangus (BR), Charolais (C) and Hereford (H) sires produced straightbred, F$\sb1$, back-cross, three-breed cross and 2- and 3-breed rotational crossbred steers (N = 708) from 1960 to 1968. Straightbred, F$\sb1$, back-cross, three-breed cross and 2-, 3- and 4-breed rotational crossbred steers (N = 1530) were produced from 1970 to 1988 by A, B, C and H sires in phase II. Direct and maternal additive and non-additive genetic effect contrasts were obtained. …

Analysis Of Host-Parasite Cospeciation: Effects Of Spatial And Temporal Scale., James W. Demastes Jan 1996

Analysis Of Host-Parasite Cospeciation: Effects Of Spatial And Temporal Scale., James W. Demastes

LSU Historical Dissertations and Theses

All species of pocket gophers (Geomyidae) are parasitized by at least one species of chewing louse (Trichodectidae), and recent genetic studies have demonstrated that a pattern of cospeciation exists between these hosts and parasites (Hafner and Nadler, 1988; Hafner et al., 1994). Little work has been done on this host-parasite system at lower taxonomic (intrageneric) levels. Although cospeciation is evident in a study of pocket gophers within the genus Geomys and their chewing lice (Geomydoecus), reticulate evolution and retention of ancestral lineages obscure the pattern (Chapter 2). One key to understanding how these patterns of cospeciation are produced and how …

The Piano Improvisations Of Chick Corea: An Analytical Study., Daniel Alan Duke Jan 1996

The Piano Improvisations Of Chick Corea: An Analytical Study., Daniel Alan Duke

LSU Historical Dissertations and Theses

Though the number of theoretical studies of jazz has increased in recent years, detailed analysis has been applied to only a small fraction of the body of jazz music. Chick Corea's Piano Improvisations are of particular interest: high quality transcriptions are available, the pieces have never been dealt with in detail, and they embody an intriguing mixture of classical and jazz styles. Analysis of Corea's Piano Improvisations raises issues as to what methods are appropriate in the analysis of jazz. There are currently two, somewhat conflicting, schools of thought. Some believe that analytical techniques traditionally applied to classical music (e.g. …

Foraging Behavior And Habitat Selection Of Insectivorous Migratory Songbirds At Gulf Coast Stopover Sites In Spring., Chao-Chieh Chen Jan 1996

Foraging Behavior And Habitat Selection Of Insectivorous Migratory Songbirds At Gulf Coast Stopover Sites In Spring., Chao-Chieh Chen

LSU Historical Dissertations and Theses

Abundance of some species of Nearctic-Neotropical migrants has been declining dramatically since 1970. Most literature about Neotropical migrants is from the breeding grounds, and some is from the wintering grounds; very little is from stopover sites. I studied foraging behavior and habitat selection of insectivorous migratory songbirds at three stopover sites along northern coast of the Gulf of Mexico during spring migrations of 1993-1995. Each migrant species had its unique combination of foraging behavior and habitat use during stopover. Migrants selected certain habitat strata and plant species and avoided others. The decrease of understory vegetation in the reduced plots had …

Synthesis Of Phosphonate Derivatives And Phosphonate Peptide Analogues., Maria De Fatima Fernandez Jan 1996

Synthesis Of Phosphonate Derivatives And Phosphonate Peptide Analogues., Maria De Fatima Fernandez

LSU Historical Dissertations and Theses

A general method for the preparation of a wide variety of phosphonate derivatives, including phosphonamides, thiophosphonamides, thiosphonates, and dithiophosphonates, from reduced phosphorus intermediates has been developed. Esters (or thioesters) of H-phosphinates are converted to the highly reactive phosphonochloridites by non-oxidative activation with dichlorotriphenylphosphorane. The phosphonochloridites react readily with alcohols, amines and thiols and after in situ oxidation or sulfurization, phosphonate derivatives can be isolated in moderate to very good yields (47-85%). This method was used to synthesize a thiophosphonate dipeptide, Boc-Val-$\Psi$(P(S)(OtBu)O) Ala-OCH$\sb3$ (15b), two thiophosphonamide dipeptides, Boc-Val-$\Psi$ (P(S)(OtBu)NH) Gly-OCH$\rm\sb2CH\sb3$ (16b) and Fmoc-Aib-$\Psi$ (P(S)(OBn)NH) Gly-OCH$\rm\sb2CH\sb3$ (20), and two phosphonate dipeptides, Fmoc-Aib-$\Psi$ …

Adaptive Harmonic Blocking Compensators., Shih-Min Hsu Jan 1996

Adaptive Harmonic Blocking Compensators., Shih-Min Hsu

LSU Historical Dissertations and Theses

This dissertation explores a new method of adaptive compensation and harmonic suppression in distribution systems. The compensator under development and investigation integrates a harmonic blocking compensator (HBC) with an adaptive balancing compensator (ABC) resulting in an adaptive harmonic blocking compensator (AHBC). Such a compensator can be used for compensating reactive power, for symmetrizing supply currents, for protecting the distribution system against load generated current harmonics and, consequently, the voltage harmonic distortion caused by non-linear loads. Harmonic blocking compensators are designed for compensating fixed loads, and they are not adaptive devices, while the adaptive capability of compensators is becoming more and …

An Information Integration Theory Analysis Of Tax Preparers' Perceived Risk Of Reporting Aggressively On Clients' Income Tax Returns., Velmer Carlene Eddlemon Jan 1996

An Information Integration Theory Analysis Of Tax Preparers' Perceived Risk Of Reporting Aggressively On Clients' Income Tax Returns., Velmer Carlene Eddlemon

LSU Historical Dissertations and Theses

Prior research shows that income tax return preparers influence the income tax compliance decisions of their clients. Information about the risk that income tax return preparers perceive in reporting aggressively on their clients' income tax returns may help the Internal Revenue Service (IRS) reduce the tax gap that exists in the United States today. This study investigates the cognitive algebra that income tax return preparers use to combine the probability of the IRS's assessing penalties for misstatements on their clients' income tax returns with the consequences (penalties, etc.) of those decisions in forming risk perceptions for reporting aggressively on their …

Physical And Functional Characterization Of Long Terminal Repeat Of Equine Infectious Anemia Virus., Soo Ho Kim

LSU Historical Dissertations and Theses

The U3 region of long terminal repeat (LTR) of equine infectious anemia virus (EIAV) contains transcriptional regulatory elements. To identify the elements in prototype (P), fetal donkey dermal cell-adapted (A), and two variant (V) EIAV LTRs, DNase I footprinting, gel shift, and transient gene expression assays were performed. The assays used U937 monocytic cells which can be induced into macrophages by 12-O-tetradecanoylphorbol-13-acetate (TPA). For study of AP1 sites, c-Jun/AP1 was also used. Footprinting with nuclear extracts from TPA-induced and uninduced U937 cells localized methylated DNA-binding protein (MDBP), PEA2, AP1, PU.1, and CCAAT enhancer-binding protein (C/EBP) sites as common elements in …
