Rhetoric And Institutional Environments: The Legitimation Of Higher Education In Twentieth Century America., Thomas J. St. Antoine Jan 1999

Rhetoric And Institutional Environments: The Legitimation Of Higher Education In Twentieth Century America., Thomas J. St. Antoine

LSU Historical Dissertations and Theses

This dissertation seeks to discover and analyze the divergent ways that higher education has been legitimated by American discourse in the twentieth century. Institutions of higher learning have been able to survive and flourish because they have been seen as essential to the health of a democracy, of a free-market economy, and of religious institutions. However, the explanations for such legitimacy have been diverse and varied. Bormann's fantasy theme analysis can account for the values and beliefs that form the institutional environments shaping and legitimating organizations such as colleges and universities. Fantasy themes expressed in popular discourse are expressions of …

Measurement Of Inclusive Charm Production In Two -Photon Collisions At Lep., Alan L. Stone Jr Jan 1999

Measurement Of Inclusive Charm Production In Two -Photon Collisions At Lep., Alan L. Stone Jr

LSU Historical Dissertations and Theses

The cross section of inclusive charm production in two-photon collisions se+e-→e +e-cc&d1;X is measured at the Large Electron Positron (LEP) collider at the European Center for Nuclear and Particle Physics (CERN). The data was obtained with the L3 detector at the center-of-mass energy of 91 GeV (LEP1) and for the first time at the center-of-mass energies from 130--183 GeV (LEP2). Charmed hadrons are identified by electrons and muons from semileptonic decays. The measured cross section agrees with next-to-leading order (NLO) QCD calculations. The direct process gg→cc&d1; is found to be insufficient to describe the data. The measured cross section values …

Musing The Garden: A Poetics Of Place And Emplacement., Scott Parker Smiley Jan 1999

Musing The Garden: A Poetics Of Place And Emplacement., Scott Parker Smiley

LSU Historical Dissertations and Theses

A walk through a garden is an immersion into a wealth of sensory and relational experiences of place. Plant varieties, color, texture, flowers, forms, pathways, light, benches, ornaments, and other experiential qualities of place work upon one's consciousness to draw one into intimate contact with the place "Emplacement" is this intimate, immersed engagement with a place, a process and state of being that erodes the boundaries we so often erect between self and environment. Traditional systematic forms of inquiry, based upon the Cartesian idea of an essential separation between object and subject, are not applicable to the study of emplacement …

Religious Art: Reflectors Of Change In The Catholic Church In New Mexico, 1830--1910., Shirley Jean Sands Jan 1999

Religious Art: Reflectors Of Change In The Catholic Church In New Mexico, 1830--1910., Shirley Jean Sands

LSU Historical Dissertations and Theses

In 1846, the United States of America began a war with the Republic of Mexico. When it was over, one of the results was the acquisition of much of current California, Arizona, Nevada, Utah, southern Colorado and New Mexico. The region was occupied by Catholic Mexicans, a fact not lost on the American Catholic hierarchy. The result is the sending of a new religious administration and the founding of what would become the Archdiocese of Santa Fe. The clergy sent were French with French notions of civilization, culture, and proper Catholic theology. These views and notions were contrary to those …

Petroleum Reservoir Simulation Using 3-D Finite Element Method With Parallel Implementation., Husam M. Yaghi Jan 1999

Petroleum Reservoir Simulation Using 3-D Finite Element Method With Parallel Implementation., Husam M. Yaghi

LSU Historical Dissertations and Theses

Modeling fluid flow around wellbores with conventional reservoir simulators is inaccurate because radial flow occurs in the vicinity of the wellbore and these simulators use cartesian coordinates. In this research, we present a more accurate wellbore simulation by incorporating the finite element method (FEM) to simulate the radial flow in the vicinity of the wellbore and interfacing this finite element wellbore model with an existing finite difference method (FDM) reservoir simulator. Although this technique was developed for a vertical well, it could also be used to accurately model a horizontal wellbore. This "hybrid" solution is for three dimensional---triphasic fluid flow …

A Novel Approach To Dna Sequencing Employing Near -Ir Fluorescence Detection Coupled With Microscale Reaction Vessels With Capillary Gel Separations., Daryl Clifford Williams

LSU Historical Dissertations and Theses

Electropherograms of oligonucleotides labeled with near-IR fluorescent dyes, separated by capillary gel electrophoresis (CGE) and detected using an ultrasensitive near-IR fluorescence detection system will be presented. A Universal M13 sequencing primer was labeled on the 5' end with a near-IR dye containing an isothiocyanate functional group. Comparison of the on-column detection limits in capillary gel electrophoresis for the near-IR-labeled sequencing primer to that of a visible fluorescein-labeled primer indicated improved sensitivity for the near-IR case. The detection limit was found to be 3.4 x 10-20 moles (SNR = 3) for the near-IR-labeled primer while the on-column detection limit for the …

Risk Management Of Aflatoxin Through Mutagenic Potential Modification And Toxin Formation By Intrinsic Components In Food., Syed Shahid Ali Jan 1999

Risk Management Of Aflatoxin Through Mutagenic Potential Modification And Toxin Formation By Intrinsic Components In Food., Syed Shahid Ali

LSU Historical Dissertations and Theses

Aflatoxins are the secondary metabolites of Aspergillus flavus and their presence in food and feed crops is unavoidable. This study evaluates the antimutagenic properties of phytic and linoleic acids in aflatoxin-affected food. A reduction in the number of revertants was a function of an increased concentration of phytic/linoleic acids and phosphotidylinositol in the Salmonella/microsomal mutagenicity assay (tester strains TA-100 and TA-98) with and without metabolic activation (S-9). Linoleic acid (10 and 100 mug/plate) and phosphotidylinositol (25mug/plate) were antimutagenic against most of the mutagens tested. Although a reduction in the number of revertants was observed in the phytic acid treatments, the …

Comprehensive Income And Its Relation To Firm Value And Transitory Earnings., Carol Callaway Dee Jan 1999

Comprehensive Income And Its Relation To Firm Value And Transitory Earnings., Carol Callaway Dee

LSU Historical Dissertations and Theses

The distinction between permanent and transitory earnings is important when using accounting earnings to predict future dividends. To the extent that net income includes transitory items, it is less useful in predicting future dividends, and thus, less useful in valuing the firm. If comprehensive income includes more transitory items than net income, it is less useful than net income in valuing the firm. This study contributes to the literature in two ways. First, a definition of permanent earnings is developed that is based on the relation between earnings and expected future dividends. The study illustrates the relation between permanent, transitory, …

Increased Nutritional Value And Oxidative Stability Of Restructured Beef Roasts With Purified Extracts From Rice Bran., Joo-Shin Kim Jan 1999

Increased Nutritional Value And Oxidative Stability Of Restructured Beef Roasts With Purified Extracts From Rice Bran., Joo-Shin Kim

LSU Historical Dissertations and Theses

The effects of semi-purified extracts of rice bran were studied in restructured beef roasts to increase nutritional value and oxidative stability. Crude rice bran oil at 0, 1, and 2% (w/w) was added to restructured beef roasts that were stored at 4°C and analyzed at 0, 7, and 14 d. Saturated fatty acid to unsaturated fatty acid (SFA/UFA) ratio decreased, vitamin E vitamers increased (p < 0.05), and cholesterol decreased in the beef roasts with rice bran oil. Thiobarbituric acid reactive substances (TBARs) numbers were lower (p < 0.05) in the beef roasts with rice bran oil after 7 days of storage and the cholesterol oxidation product, 7-ketocholesterol, decreased in a similar manner. The addition of 2% rice bran oil (RBO) was effective in increasing nutritional value and reducing the level of oxidative degradation. Beef roasts containing either rice fiber (RF) or RF/RBO had higher oxidative stability (p < 0.05) during storage (0, 4, and 8 d) compared to control roasts, with no additive. TBARs value and 7-ketocholesterol of beef roasts with RF and RF/RBO were lower (p < 0.05) than those of the control during storage. SFA/UFA ratio was significantly reduced in beef roasts with additives, whereas vitamin E vitamers and UFA were higher (p < 0.05) in the roasts with RF/RBO. Beef roasts containing RF and RBO were acceptable to consumers in sensory attributes. Cholesterol autoxidation was examined in an aqueous meat model system with different levels of nonsaponifiable fraction from rice bran (0, 700, 1400, and 2100 ppm). The effect of nonsaponifiable fraction was determined at 4 h intervals for 16 h at pH 5.5 and 80°C. Increased oxidation time reduced (p < 0.05) total vitamin E vitamers and cholesterol concentration. Oryzanol was not significantly reduced with the 2100 ppm treatment after 4 h cholesterol oxidation. An increase in the nonsaponifiable fraction resulted in a decrease (p < 0.05) in the formation of 7-ketocholesterol. The highest level of additive (2100 ppm) was the most effective in inhibiting cholesterol autoxidation; the order of inhibition was 91.7% (2100 ppm) > 81.8% (1400 ppm) > 63.1% (700 ppm).

Performing Dracula: A Critical Examination Of A Popular Text In Three Sites Of Performance., Jonathan Matthew Gray Jan 1999

Performing Dracula: A Critical Examination Of A Popular Text In Three Sites Of Performance., Jonathan Matthew Gray

LSU Historical Dissertations and Theses

Dracula is a significant example of a popular phenomenon with a long and ongoing history of productive circulation in Anglo-American culture. While theorists of popular culture often use the term "performance" in their explanations of the popularity and meaningful operations of such phenomena in a culture, they do not always provide concrete definitions of what they mean by performance. This study provides an analysis of the roles performance plays in a specific popular culture phenomenon. Identifying Bram Stoker's Dracula as a nexus for a broader cultural activity, this study examines articulations of Dracula in performances and texts that both precede …

Folk Housing In Northeastern Mexico: A Key To Culturogeographic Regionalization., Scott Stuart Brown Jan 1999

Folk Housing In Northeastern Mexico: A Key To Culturogeographic Regionalization., Scott Stuart Brown

LSU Historical Dissertations and Theses

Folk housing is one of the elements of material culture which geographers often employ in understanding the cultural aspects of regional studies. As one of the most obvious features of the cultural landscape, folk housing serves as a tool in the determination of culturogeographic regions, the final objective of this study. In this atomistic regional approach, geometry is the principle feature of interest. In other words, the one-dimensional plan type and the three-dimensional form class are the elements of focus in order to distinguish regionality. As opposed to other sub-systems of structural analysis, geometry, especially house from, distinguishes regions of …

Executive Compensation And The Investment Opportunity Sets Of Initial Public Offerings., Tanya S. Nowlin Jan 1999

Executive Compensation And The Investment Opportunity Sets Of Initial Public Offerings., Tanya S. Nowlin

LSU Historical Dissertations and Theses

This study examines how the components of CEO compensation contracts vary with characteristics of initial public offering firms (IPOs). There are two major steps in the analysis. The first step investigates whether IPOs exhibit variation in characteristics that theory predicts affect compensation contracts. The second step investigates whether these differences across firms are related to the use of accounting versus non-accounting performance evaluation measures, levels of base salary and cash bonuses, and the value of stock options for CEOs. Results from this study support the importance of modeling compensation components separately. Theoretical constructs differ depending on the type of compensation …

Beyond Black And White: The Civil Rights Movement In Baton Rouge, Louisiana, 1945--1972., Mary Jacqueline Hebert

LSU Historical Dissertations and Theses

The civil rights movement in Baton Rouge, Louisiana, went beyond a battle between blacks and whites over segregation. Within each racial group, factions developed along class, generational, and educational lines. Interactions among these groups shaped the nature and pace of change in the city. In 1945, black World War II veterans launched the movement. Committed to working within the legal system, they established voter registration schools, participated in the 1953 bus boycott, and sued to equalize teachers' salaries and to integrate public schools. In the 1960s, black college students rose to prominence in the movement and used direct action, including …

Characterization Of Solidification/Stabilization Of Chromium Wastes In Cement Matrix., Aijun Zhang Jan 1999

Characterization Of Solidification/Stabilization Of Chromium Wastes In Cement Matrix., Aijun Zhang

LSU Historical Dissertations and Theses

A cement-based solidification/stabilization (S/S) system of Cr wastes treatment has been studied in this program. A combination of the two techniques; namely reduction of Cr(VI) to Cr(III) and simultaneous immobilization within a cement matrix, has been found to be effective and practical to treat Cr wastes. Cr(VI) can not be easily and effectively-immobilized in the S/S system unless being reduced to Cr(III). Ferrous compounds are used as reducing reagents. The reduction not only removes the toxic Cr(VI) species but also results in the low-solubility precipitation of (CrxFe 1-x) (OH)3(s) in the S/S system. Long-term and short-term samples were tested through …

Molecular Genetics And Functions Of Herpes Simplex Virus Type 1 (Hsv-1) Glycoprotein K (Gk) In The Morphogenesis Of Infectious Virion Particles., Timothy Paul Foster

LSU Historical Dissertations and Theses

Herpes simplex virus type 1 (HSV-1) specifies at least 11 glycoproteins that are expressed in infected cells and in virions. HSV-1 enters into cells via fusion of the viral envelope with cellular membranes and can spread to adjacent cells via fusion of cellular membranes. Glycoproteins gB, gD, gH, and gL are known to be essential for virus entry, virus spread, and virus induced cell-to-cell fusion. The majority of spontaneous single amino acid changes that cause extensive cell fusion map within the UL53 gene encoding glycoprotein K (gK); however, the role of gK in virus entry and virus egress had not …

Relating Process Philosophy To The Classroom: An Exploration Of Alfred North Whitehead's Educational Vision., Janis Pardue Hill

LSU Historical Dissertations and Theses

This dissertation is an exploration of the connections between the process philosophy and the educational thinking of Alfred North Whitehead. It develops the theory that Whitehead's philosophy of process is evident in "embryonic" form in his earlier educational writings, as well as The Aims of Education and Other Essays (1929), and that the complexities of process thinking are as intertwined and interconnected with the principles of process educational thought as the actual entity is intertwined and interconnected with the complex relations involved in its concrescence. The ultimate aim is to provide a clear picture of Whitehead's vision of education and …

Family Portraits: Contemporary Women Novelists And The Nuclear Family., Tamra Lynn Horton Jan 1999

Family Portraits: Contemporary Women Novelists And The Nuclear Family., Tamra Lynn Horton

LSU Historical Dissertations and Theses

A society whose economy becomes increasingly dependent on commodity fetishism cultivates obsessive materialistic desire in its subjects. The demand for mass consumerism buoys reification, a mania wherein human beings are analogous to goods and vice versa. Successful reification depends upon hegemonic apparatuses: social, legal, and political agencies of dominant ideology. Reification is perhaps most fully realized in the form of fetishized human relationships. In the United States today, the most coercive and unassailable hegemonic apparatus is the institutionalized nuclear family, a social and legal affiliation between individuals so dogmatically fetishized as to have become compulsory. Contemporary American women writers are …

Factors Influencing Effectiveness Of Exhibit Displays On Family Learning In A Public Aquarium., Kodi Rae Jeffery

LSU Historical Dissertations and Theses

An important goal in science education reform is to create a scientifically literate society. The American Association for the Advancement of Science (1989b) has stated that for people to understand biology, they must first have personal experiences with it. There are severe limitations on the types of firsthand biology experiences available in the classroom. Informal learning institutions, however, are not limited by these constraints. Visitors enjoy a free-choice environment, where they can thoroughly explore things unavailable in most classrooms. Thus, museums are key resources that may help society achieve scientific literacy. This study asked what aspects of the Aquarium of …
