The New South Gubernatorial Campaigns Of 1970 And The Changing Politics Of Race., Donald Randy Sanders Jan 1998

The New South Gubernatorial Campaigns Of 1970 And The Changing Politics Of Race., Donald Randy Sanders

LSU Historical Dissertations and Theses

In 1970 four young racially moderate Democrats won the governor's chairs of Arkansas, Florida, South Carolina and Georgia. These southern gubernatorial elections and the subsequent inaugural speeches signaled a transformation of racial politics in the region. As the campaigns began, however, persistent ambivalence concerning the pace of integration and court-ordered busing of school children to achieve racial balances tempted many politicians to exploit these concerns. Their efforts failed; southerners had decided to obey the law. The successful candidates understood that the electorate had come to this decision with varying degrees of enthusiasm and that their campaigns must reflect this ambivalence; …

Diagnosis Of Poor Pdc Bit Performance In Deep Shales., John Rogers Smith Jan 1998

Diagnosis Of Poor Pdc Bit Performance In Deep Shales., John Rogers Smith

LSU Historical Dissertations and Theses

This study was performed to diagnose the cause of poor PDC bit performance in deep, overpressured shales. Deep, overpressured wells account for a disproportionate share of all drilling costs, about 27 percent. The effect of bit performance on this cost is significant, about $2.9 billion annually in overpressured formations alone. Bit performance in deep, overpressured formations when using water-based muds is especially poor, adding at least \$500 million annually to worldwide drilling costs. This problem is described as the slow drilling shale problem and is shown to exist worldwide. Potential causes of this problem identified in the technical literature include …

Education For Liberation As (An) African-American Folk Theory., Denise Marie Taliaferro Jan 1998

Education For Liberation As (An) African-American Folk Theory., Denise Marie Taliaferro

LSU Historical Dissertations and Theses

African American people have historically expressed great faith in education as a path toward liberation. It is an idea--education for liberation--that is pervasive in African American discourse. It is well documented in research that focuses on the efforts of African Americans to educate themselves despite slavery, the fall of reconstruction, a brutal Jim Crow system, and desegregation in lieu of integration (Anderson, 1988; Lerner, 1972; Watkins, 1993). Yet despite our faithful proclamations, we have been represented otherwise in mainstream educational discourse. Intellectual inferiority, cultural deprivation, underachievement, and at-risk have been some of the terms used to explain the consistent and …

The Solo Piano Music Of Violet Archer: A Study Of Selected Didactic Works., Angela Sue Willoughby Jan 1998

The Solo Piano Music Of Violet Archer: A Study Of Selected Didactic Works., Angela Sue Willoughby

LSU Historical Dissertations and Theses

Canadian composer Violet Archer has made contributions to virtually every genre of musical composition. Her avid interest in orchestral music manifests itself in the large number of instrumental works she has composed, and her love of setting poetry and scripture can be seen in her music for voice and chorus. The works for solo piano span the entire length of her career and represent a significant portion of her total output. Aside from a scant number of brief analytical sketches of various pieces in periodicals and biographical sections of books, there is no comprehensive study of Archer's music for piano. …

Magnetic Field Evolution In Neutron Stars., Erik Jordan Young Jan 1998

Magnetic Field Evolution In Neutron Stars., Erik Jordan Young

LSU Historical Dissertations and Theses

Magnetized neutron stars provide the basic model for radio pulsars. They also play a fundamental role in the theory of pulsating X-ray sources and explaining the origin of millisecond radio pulsars. In an effort to better understand these interesting and fundamentally important astrophysical systems, this dissertation studies the magnetic evolution of neutron stars with a dipole field supported in the crust. We explore their evolution both as isolated systems and as accreting objects in binary systems. We investigate how the incorporation of the gravitational field of the neutron star core into the spacetime occupied by a dipole field in the …

Origins Of Black Catholic Parishes In The Archdiocese Of New Orleans, 1718-1920., John Bernard Alberts Jan 1998

Origins Of Black Catholic Parishes In The Archdiocese Of New Orleans, 1718-1920., John Bernard Alberts

LSU Historical Dissertations and Theses

During the early eighteenth century, Capuchin missionaries as well as Ursuline nuns built and maintained churches and schools for all people in south Louisiana, no matter their race or social status. Under French and Spanish colonial rule, black Catholics supported all efforts towards interracial worship. After 1803, the diocese's inclusive practices continued. By 1861 proselytization of large numbers of free people of color and slaves resulted in Catholic congregations with roughly equal numbers of blacks and whites. When parishes were officially created in 1861, they had an integrated membership. Interracial parishes survived the traumas of the Civil War and persisted …

A Methodology To Identify Stranded Generation Facilities And Estimate Stranded Costs For Louisiana's Electric Utility Industry., Robert Frank Cope Iii Jan 1998

A Methodology To Identify Stranded Generation Facilities And Estimate Stranded Costs For Louisiana's Electric Utility Industry., Robert Frank Cope Iii

LSU Historical Dissertations and Theses

The electric utility industry in the United States is currently experiencing a new and different type of growing pain. It is the pain of having to restructure itself into a competitive business. Many industry experts are trying to explain how the nation as a whole, as well as individual states, will implement restructuring and handle its numerous "transition problems.". One significant transition problem for federal and state regulators rests with determining a utility's stranded costs. Stranded generation facilities are assets which would be uneconomic in a competitive environment or costs for assets whose regulated book value is greater than market …

The Role Of Curved Dna In Bacillus Subtilis Rna Polymerase-Promoter Interactions., Murad Mohammed Odeh Jan 1998

The Role Of Curved Dna In Bacillus Subtilis Rna Polymerase-Promoter Interactions., Murad Mohammed Odeh

LSU Historical Dissertations and Theses

Intrinsically curved DNA upstream of promoters was shown to affect the Bacillus subtilis RNA polymerase-promoter interactions leading to transcription initiation. The Alu156, a B. subtilis bacteriophage dependent on the curved DNA located immediately upstream of the $-$35 region, and modified forms of Alu156 were used. Promoters were examined using gel retardation and DNase I footprinting assays. DNase I footprinting analysis of the Alu156 promoter demonstrated a unique pattern of DNase I hypersensitive and protected sites characteristic of DNA wrapped around the protein. This wrapping was observed upstream of the curved DNA. To examine the nature of curved DNA, the native …

Cloning And Identification Of Chlamydomonas Reinhardtii Genes And Proteins Upregulated Under Low Carbon Dioxide Conditions., Aravind Somanchi Jan 1998

Cloning And Identification Of Chlamydomonas Reinhardtii Genes And Proteins Upregulated Under Low Carbon Dioxide Conditions., Aravind Somanchi

LSU Historical Dissertations and Theses

A mechanism that concentrates CO$\sb2$ in cells of Chlamydomonas reinhardtii, is induced when cells are grown at low CO$\sb2$ conditions. This mechanism increases the CO$\sb2$ concentration at the site of RuBisCO, and thereby improves the efficiency of C$\rm\sb{i}$ uptake and fixation. Cells adapting to low CO$\sb2$ show significant physiological changes. Few of the genes encoding proteins needed to produce these changes have been identified. A cDNA library has been constructed from C. reinhardtii to identify genes involved in these changes. The cloning and identification of several cDNAs that are upregulated under low CO$\sb2$ conditions are reported here. The possible roles …

Directed Search In K-System Reconstruction., Christopher W. Branton Jan 1998

Directed Search In K-System Reconstruction., Christopher W. Branton

LSU Historical Dissertations and Theses

K-systems analysis is a factor analysis technique created through the generalization of key reconstructability analysis definitions and algorithms. The method is applied to functions on systems of discrete variables to discover a set of factors which can explain the bulk of the function's variation from the mean. K-systems analysis uses principles of information theory to reveal interactions which are often masked by the assumptions implicit in traditional methods. The method has been used successfully to analyze systems in several disciplines. Despite the success of k-systems analysis, obstacles to the creation of a mature methodology still exist. Some issues and open …

An Exploratory Study Of The Impact Of Hypermedia-Based Approach And Science-In-Fiction Approach For Instruction On The Polymerase Chain Reaction., Lynda A. Britton

LSU Historical Dissertations and Theses

Exploration of meaningful learning of the polymerase chain reaction (PCR) followed instruction by a researcher-developed hypermedia computer program that incorporated human constructivist principles and a "science-in-fiction" chapter of a novel that described PCR. Human constructivism is the Ausubel-Novak-Gowin (1997) meaningful learning theory that supports science learning through graphic representations and multiple examples. Science-in-fiction is a new genre of fiction introduced by the prominent scientist, Carl Djerassi, to engender an appreciation for science, and its ethical dilemmas. Chapter 19 of Djerassi's 1994 novel, The Bourbaki Gambit, was placed into hypermedia format to standardize the presentation. As part of a clinical microbiology …

Purification Of Porphobilinogen Deaminase And The Sequencing And Expression Of Thehemc Gene Of Rhodobacter Capsulatus., Keith A. Canada Jan 1998

Purification Of Porphobilinogen Deaminase And The Sequencing And Expression Of Thehemc Gene Of Rhodobacter Capsulatus., Keith A. Canada

LSU Historical Dissertations and Theses

Rhodobacter capsulatus uses the common tetrapyrrole pathway to synthesize heme, bacteriochlorophyll, siroheme and vitamin B-12. As part of our studies on the regulation of this pathway, the product of the hemC gene, porphobilinogen deaminase was purified approximately 200-fold. The molecular weight, isoelectric point, pH optimum and Km of the enzyme were all similar to other porphobilinogen deaminases. The stoichiometry of the enzyme was found not to be the expected four porphobilinogens used per one uroporphyrin formed. Rather a 9:1 ratio was typically seen. Further study of this atypical ratio uncovered evidence of possible in vivo regulation of porphobilinogen deaminase dependant …

An Examination Of Automatic Versus Strategic Semantic Priming Effects In Broca's Aphasia., Janice Feagin Del Toro Jan 1998

An Examination Of Automatic Versus Strategic Semantic Priming Effects In Broca's Aphasia., Janice Feagin Del Toro

LSU Historical Dissertations and Theses

The ability to recognize words is frequently investigated using a lexical decision (LD) priming task in which subjects make rapid yes/no judgements as to whether visually presented letter strings (targets) are words or not. A well established finding is that words are recognized faster when preceded by related words. This "semantic priming effect" is believed to represent both automatic and conscious, strategic driven processes. One factor that influences the degree to which subjects recognize words automatically or consciously, is the time interval between the presentation of the prime and the presentation of the target. This is referred to as the …

Subterranean Echoes: Curriculum Theory As Cultural Studies., Toby Allan Daspit Jan 1998

Subterranean Echoes: Curriculum Theory As Cultural Studies., Toby Allan Daspit

LSU Historical Dissertations and Theses

Cultural studies has emerged in recent decades as a popular realm of academic inquiry (During, 1993). Giroux (1994), while noting the field's increased acceptance, ponders why cultural studies has yet to permeate critical analyses of education and simultaneously questions cultural studies' reticence in considering schools as an important site of cultural production. Edgerton (1996) concurs with Giroux and notes that cultural studies' use in colleges of education is extremely rare. The realm of popular culture, one of the central foci of cultural studies, has especially been marginalized in academic discourses. My project is to explore the implications of curriculum theory …

The Nature And Extent Of Species Interactions With The United States Gulf Menhaden Fishery., Janaka Anthony De Silva Jan 1998

The Nature And Extent Of Species Interactions With The United States Gulf Menhaden Fishery., Janaka Anthony De Silva

LSU Historical Dissertations and Theses

I employed categorical techniques to explain patchy data on the releasable bycatch in the U.S. Gulf of Mexico menhaden fishery looking for species and areas of potential concern and potential solutions. For fishing grounds east of the Mississippi River, the odds of observing sets with high bycatch in spring and summer were greater than in the fall. Furthermore, spring bycatch rates were higher east of 89°W than in areas west of 93°W. Correspondence analysis indicated that the fate of the releasable bycatch could be classified into three major species-fate groupings. Two distinct bycatch species assemblages from April through August that …

Materials Fluxes Across Different Scales Of Time And Space In The Rhone Delta, France., Philippe Francois Hensel Jan 1998

Materials Fluxes Across Different Scales Of Time And Space In The Rhone Delta, France., Philippe Francois Hensel

LSU Historical Dissertations and Theses

A study of materials fluxes across different scales of time and space was conducted in the Rhone Delta, France, to test the applicability of a conceptual model of deltaic ecosystem function in a scenario of accelerated sea-level rise to a mediterranean delta which has been heavily altered by human activities. Natural pulsing events such as tides, river floods and storms cause sediment surfaces to maintain elevation in the face of relative sea level rise through the process of soil formation. These pulses also enhance ecosystem function through habitat creation, food production, materials transformation, water quality and storm and flood protection. …
