Genetic Population Structure Of A Species Complex Of Blue Mussels (Mytilus Spp.)., Shane Kevin Sarver Jan 1993

Genetic Population Structure Of A Species Complex Of Blue Mussels (Mytilus Spp.)., Shane Kevin Sarver

LSU Historical Dissertations and Theses

Mussels representing two species (Mytilus trossulus and M. galloprovincialis) were collected from 28 littoral locations on the Pacific coast of the USA, and examined for genetic variation at 15 allozyme loci. Eleven samples from a region of suspected hybridization between the two species were also analyzed for variation in seven shell characters. Analysis of allozyme data by principal components analysis revealed three groups based on first principal component scores, and were identified as M. trossulus, M. galloprovincialis and hybrids. Canonical discriminate analysis of seven shell characters was less successful in separating mussels based on morphological criteria alone. To explore the …

Reliability Analysis Of The Hypercube Architecture., Sieteng Soh Jan 1993

Reliability Analysis Of The Hypercube Architecture., Sieteng Soh

LSU Historical Dissertations and Theses

This dissertation presents improved techniques for analyzing network-connected (NCF), 2-connected (2CF), task-based (TBF), and subcube (SF) functionality measures in a hypercube multiprocessor with faulty processing elements (PE) and/or communication elements (CE). These measures help study system-level fault tolerance issues and relate to various application modes in the hypercube. Solutions discussed in the text fall into probabilistic and deterministic models. The probabilistic measure assumes a stochastic graph of the hypercube where PE's and/or CE's may fail with certain probabilities, while the deterministic model considers that some system components are already failed and aims to determine the system functionality. For probabilistic model, …

The Southern Baptist Convention Reformation, 1979-1990: A Social Drama., William Stanley Stone Jr Jan 1993

The Southern Baptist Convention Reformation, 1979-1990: A Social Drama., William Stanley Stone Jr

LSU Historical Dissertations and Theses

From Michael Thompson, Richard Ellis, and Aaron Wildavsky's cultural theory perspective, the authoritarian and the individualistic ways of life have coexisted in the Southern Baptist Convention (SBC) for more than a century. In 1979, Southern Baptist fundamentalists began a concerted movement to reform the SBC according to authoritarian beliefs and social practices. From Victor Turner's dramaturgical perspective, the 1979-1990 Southern Baptist controversy was a social drama that transferred power and reshaped Southern Baptists' perception of the past, present, and future. Rhetorical strategies facilitated each stage of the fundamentalists' reformation movement and the moderate counter movement. The present study symbolically explicates …

New Approaches And Techniques For Drawing Lines On Raster Devices., Philip Arthur Graham Jan 1993

New Approaches And Techniques For Drawing Lines On Raster Devices., Philip Arthur Graham

LSU Historical Dissertations and Theses

Two basic approaches to drawing lines on raster devices are discussed and improved upon. The first is the recursive bisection algorithm, a method recently proposed by John Rankin, which uses a fractal approach to draw lines. The second is the double-step algorithm, a method proposed by Xiaolin Wu and Jon Rokne, which is based on the traditional Bresenham approach to drawing lines. Although a number of line drawing algorithms exist, the algorithms presented are of interest because the double-step algorithm is one of the fastest line drawing algorithms. Furthermore, since lines are self-similar and fractals have been found to be …

Tectonic Implications Of Fission-Track Thermochronology And Amphibole Thermobarometry Studies Of The Northern Peninsular Ranges Batholith, Southern California., Peter Gillham George Jan 1993

Tectonic Implications Of Fission-Track Thermochronology And Amphibole Thermobarometry Studies Of The Northern Peninsular Ranges Batholith, Southern California., Peter Gillham George

LSU Historical Dissertations and Theses

Fission-track data from the San Jacinto Mountains and the Palomar Mountain-Escondido study area indicate that the Late Cretaceous history of the Peninsular Ranges batholith is marked by a series of major cooling events. Coupled with geobarometry measurements and field observations, these data allow for a greater understanding of the nature and timing of both local and regional tectonic events. In the eastern Peninsular Ranges, west-vergent thrusting along the Santa Rosa mylonite belt at $\sim$99-94 Ma was followed by major extensional faulting between $\sim$94 and 92 Ma. Amphibole geobarometry of mylonites indicate that $\sim$10-18 km of crustal thickening occurred as a …

Performance And Organized Labor In Depression America: Community And Contestation. (Volumes I And Ii)., Kirk Wayne Fuoss Jan 1993

Performance And Organized Labor In Depression America: Community And Contestation. (Volumes I And Ii)., Kirk Wayne Fuoss

LSU Historical Dissertations and Theses

This study investigates the relationship among cultural performance, community, and contestation in two depression-era, organized labor social dramas. The major arguments developed in the study are summarized in the following three contentions. First, performances are inherently contestatory. Second, contestation and community stand in an interdependent rather than oppositional relationship to one another. Third, a dialectical relationship exists between performance and community whereby communities not only produce but are produced by performances. Chapter one defines key concepts and offers a rationale for the study. Two rationales for exploring the relationship among cultural performances, contestation, and community are advanced. First, despite the …

A Study Of Deoxyribooligonucleotide Duplexes Containing An Unpaired Base Or Mismatched Base Pairs Using: (I) Molecular Modeling, And, (Ii) Proton Exchange Measured With Nuclear Magnetic Resonance Spectroscopy., Bonnie Mary Gunn-Tolson Jan 1993

A Study Of Deoxyribooligonucleotide Duplexes Containing An Unpaired Base Or Mismatched Base Pairs Using: (I) Molecular Modeling, And, (Ii) Proton Exchange Measured With Nuclear Magnetic Resonance Spectroscopy., Bonnie Mary Gunn-Tolson

LSU Historical Dissertations and Theses

Mismatched base pairs have been implicated in mutations and arise from transitions or transversions of the base pairs during replication. An oligonucleotide duplex containing adjacent G$\cdot$A and A$\cdot$A mismatches, d(GCGAAT)$\cdot$d(ATAAGC), has been investigated using molecular mechanics and dynamics. Experimental NMR data obtained for a related molecule was used to constrain the model which suggested an unusual hydrogen-bonding for both mismatches. Between the G$\cdot$A and A$\cdot$A mismatches, defined by the unusual base pairing, there is a large twist angle. The remainder of the base pairs are B-DNA conformations. The effect of an unpaired base on the local geometry of an oligonucleotide …

The Role Of Pre-Response And Post-Response Augmented Learning Variables In Motor Skill Acquisition., M. Jerome Hand Jan 1993

The Role Of Pre-Response And Post-Response Augmented Learning Variables In Motor Skill Acquisition., M. Jerome Hand

LSU Historical Dissertations and Theses

Verbal instructions, modeling, videotaped replay (VTR), and knowledge of performance (KP) are augmented learning variables that practitioners commonly present to learners to facilitate the acquisition of motor skill. Two experiments are reported that sought to determine how each of these variables affect skill acquisition and the cognitive representations responsible for producing such skill. Learning variables were classified as pre-response (verbal instructions and modeling) or post-response (VTR and KP), depending whether the information given pertained to the subsequent trial or the previous trial, respectively. Experiment 1 investigated the effects of each variable separately, while Experiment 2 examined whether a combination of …

High Performance Software Reconfiguration In The Context Of Distributed Systems And Interconnection Networks., Vinayak Gajanan Hegde Jan 1993

High Performance Software Reconfiguration In The Context Of Distributed Systems And Interconnection Networks., Vinayak Gajanan Hegde

LSU Historical Dissertations and Theses

Designed algorithms that are useful for developing protocols and supporting tools for fault tolerance, dynamic load balancing, and distributing monitoring in loosely coupled multi-processor systems. Four efficient algorithms are developed to learn network topology and reconfigure distributed application programs in execution using the available tools for replication and process migration. The first algorithm provides techniques for transparent software reconfiguration based on process migration in the context of quadtree embeddings in Hypercubes. Our novel approach provides efficient reconfiguration for some classes of faults that may be identified easily. We provide a theoretical characterization to use graph matching, quadratic assignment, and a …

A Performance-Centered Approach To Leslie Marmon Silko's "Ceremony"., Randall Thomas Hill Jan 1993

A Performance-Centered Approach To Leslie Marmon Silko's "Ceremony"., Randall Thomas Hill

LSU Historical Dissertations and Theses

This study argues that in Ceremony Leslie Marmon Silko rehearses her Laguna-Keres culture and her culture's interactions with others. She accomplishes this rehearsal by employing representations of performances from the Laguna people as well as other cultures. To establish the context of my argument, first I offer a brief exploration of the current critical interest in Native American arts and cultures, review questions involved in defining the parameters for a study of Native American novels, examine the significance of Native novels for performance scholarship, and review performance studies scholars' responses to Native texts. Second, I review methodologies from a variety …

Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman Jan 1993

Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman

LSU Historical Dissertations and Theses

As a dimension of privacy regulation, self-disclosure is the means through which individuals manage the psychological boundary area between the inner, private world and the outer, public world of interaction with others. In communication research, a gap has been noted between self-disclosure as defined by scientific method and self-disclosure as it is experienced by people in their daily life. This study reduces that gap by investigating disclosure decisions about a major life experience through the thick perspectives of the individuals themselves. Disclosure is examined as a context-embedded communicative process. To provide a thick description of disclosure decisions, an ethnographic methodology …

Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu Jan 1993

Toward Understanding Post-Structuralism And Curriculum., Wen-Song Hwu

LSU Historical Dissertations and Theses

This dissertation describes extensions of post-structuralism in contemporary curriculum discourses. Post-structuralist thought is mainly associated with the seminal work of Michel Foucault, Jacques Derrida, Gilles Deleuze, Jean-Francois Lyotard, and Michel Serres. Post-structural criticism and analysis challenge prevailing structuralist approaches and question the fundamental assumptions upon which these approaches rest. A key assumption of structural approaches is that all phenomena are constituted by an underlying structure. In curriculum, these structural assumptions (often scientific) remain unacknowledged and thus are immunized against criticism; rather, they are incorporated into the preferred structural analyses, interpretations, and organizations promoted by the promise of order and rationality. …

In Situ Determination Of Capillary Pressure And Relative Permeability Curves Using Well Logs., Adel Afifi Ibrahim Jan 1993

In Situ Determination Of Capillary Pressure And Relative Permeability Curves Using Well Logs., Adel Afifi Ibrahim

LSU Historical Dissertations and Theses

A pressure profile obtained from the formation tester defines the wettability, free water level, and hydrocarbon and water densities as well as the capillary pressure above the free water level. Correlating the pressure values to the water saturation values determined from the resistivity logs results in a capillary pressure/water saturation, $\rm P\sb{c}(S\sb{w}),$ curve characteristic of the reservoir. A relative permeability curve then can then be derived from this $\rm P\sb{c}(S\sb{w})$ curve using empirical relationships. This approach was tested in the laboratory using an eight-foot vertical sandstone core to simulate the formation. The core was fitted with electrode arrays, and resistivity …

Partial Purification And Characterization Of A Naturally-Occurring Inhibitor Of Viral Polyprotein Processing., Shaffina John Jan 1993

Partial Purification And Characterization Of A Naturally-Occurring Inhibitor Of Viral Polyprotein Processing., Shaffina John

LSU Historical Dissertations and Theses

An inhibitor activity that prevents the proteolytic processing of Cowpea Mosaic Virus (CPMV) polyprotein has been discovered in crude wheat germ extracts. CPMV is a comovirus that replicates via the synthesis of two polyproteins which are subsequently cleaved by a viral proteinase to yield the functional viral proteins. Since this scheme of replication is common to many other viral groups, a potential target for antivirals is the proteinase responsible for polyprotein processing. A partial purification of this wheat germ inhibitor activity has been accomplished by classical protein purification methods which include ammonium sulfate precipitation, heat treatment, ion exchange, size exclusion …

Synthesis, Isolation, Characterization And Homogeneous Catalytic Reactions Of Racemic- And Meso-Metal Binucleating Tetraphosphine Complexes., Booker Washington Ochieng Juma

LSU Historical Dissertations and Theses

The tetraphosphine ligand Et$\sb2$PCH$\sb2$CH$\sb2$P(Ph)CH$\sb2$P(Ph)CH$\sb2$CH$\sb2$PEt$ \sb2$ (to be referred to as et,ph-P4) was designed to both bridge and chelate two metal centers and hold them in general proximity to investigate bimetallic cooperativity in homogeneous catalysis. The internal phosphines of et,ph-P4 are chiral, thereby generating a pair of diastereomers: the racemic, and the meso. These are produced in approximately equal amounts from the ligand synthesis. This project has concentrated on the separation and isolation of diastereomerically pure forms of et,ph-P4 to determine individual hydroformylation catalytic activity of each bimetallic complex. Complexes of Ni(NCS)$\sb2$ with et,ph-P4 were effective in accomplishing this separation by …

On The Characterization Of Finite Dimensional Hida Distributions., Kyoung Sim Lee Jan 1993

On The Characterization Of Finite Dimensional Hida Distributions., Kyoung Sim Lee

LSU Historical Dissertations and Theses

The mathematical framework of white noise analysis is based on an infinite dimensional analogue of the Schwartz distribution theory. The Lebesgue measure on $\IR\sp{k}$ is replaced with standard Gaussian measures $\mu$ on infinite dimensional spaces. There is an infinite dimensional analogue $({\cal E})\subset L\sp2({\cal E}\sp*,\mu)\subset({\cal E})\sp*$ of a Gel'fand triple ${\cal E}\subset E\subset{\cal E}\sp*$ which is obtained from ${\cal S}(\IR\sp{k})\subset L\sp2(\IR\sp{k})\subset{\cal S}\sp*(\IR\sp{k})$ in a general setup. There are spaces $({\cal E}\sp\beta),({\cal E}\sp\beta)\sp*, \beta\in\lbrack 0,1)$ with $({\cal E}\sp\beta)\subset({\cal E})\subset L\sp2({\cal E}\sp*,\mu)\subset({\cal E})\sp*\subset({\cal E}\sp\beta)\sp*.$. The compositions of Schwartz distributions and Gaussian random variables have been discussed. A new Gel'fand triple ${\cal H}(\IR\sp{k})\subset{\cal …

The Tio Family: Four Generations Of New Orleans Musicians, 1814-1933. (Volumes I And Ii)., Charles E. Kinzer

LSU Historical Dissertations and Theses

Thomas Louis Marcos Tio (1828-c1881), and his uncle, Louis Hazeur (c1792-1860), were active musicians in the antebellum free-colored society of New Orleans. Two of Thomas Tio's sons, Louis (1862-1922) and Lorenzo (1867-1908), in turn became involved as clarinetists and arrangers in the marching bands, minstrel shows, and pit orchestras of late nineteenth-century New Orleans. The most widely known of the Tios, however, was Lorenzo, Jr. (1893-1933), who exerted a prime influence on the development of the early style of jazz clarinet performance. The teacher of Sidney Bechet and Barney Bigard, he performed with many jazz groups in New Orleans, Chicago, …
