The Rhetoric Of Lee Iacocca: The Man, The Myth, The Message (Michigan)., Jayne Margaret Megginson

LSU Historical Dissertations and Theses

The purpose of this study was to analyze the rhetoric of Lee A. Iacocca as expressed in the thoughts and actions of the man; to explore rhetorical aspects of his popular myth-hero qualities; and to examine the rhetorical strategies Iacocca used in presenting his message. Criteria for the study were based on the rhetorical theories of Ernest Bormann, Lloyd Bitzer, and Kenneth Burke, with an emphasis on two of Aristotle's canons. In addition, the pattern for the myth-hero as presented by Joseph Campbell was a guide. These concepts blended into an interrelationship which helped illuminate the dimensions of Iacocca's rhetorical …

An Exploration Of The Type A Behavior Pattern In Chronic Headache Sufferers., Neil Bruce Rappaport

LSU Historical Dissertations and Theses

Recently, investigations have examined the possible link between the Type A Behavior Pattern (TABP) and chronic headache. Several studies have indicated a significant relation between Type A, as measured by the Jenkins Activity Survey (JAS), and headache frequency. As well, several researchers have noted the similarities in the descriptions of the Type A individual and those characteristics of the "migraine personality." To date, no prospective study has examined whether that set of characteristics ascribed to migraineurs is in fact the TABP. The second focus of this investigation was to provide a comprehensive description of the psychological functioning of Type A …

Glyphosate Catabolism By Pseudomonas Sp. Pg2982., Dean Lee Shinabarger

LSU Historical Dissertations and Theses

The pathway for the degradation of glyphosate (N-phosphonomethylglycine) by Pseudomonas sp. PG2982 has been determined using metabolic radiolabeling experiments. Radiorespirometry experiments utilizing 3-('14)C glyphosate revealed that approximately 50-59% of the C3 carbon was oxidized to CO(,2). Fractionation of stationary phase cells labeled with 3-('14)C glyphosate revealed that from 45-47% of the assimilated C3 carbon is distributed to proteins and that the amino acids methionine and serine are highly labeled. The nucleic acid bases adenine and guanine received 90% of the C3 label that was incorporated into nucleic acids, and the only pyrimidine base labeled was thymine. These results indicated that …

The Type A Behavior Pattern And Acth Response To The Stress Of Cardiac Catheterization., Marie Carmen Veitia

LSU Historical Dissertations and Theses

There is substantial evidence to indicate that the Type A Behavior Pattern is associated with an increased risk of coronary heart disease. Recent research has shown that Type As, as compared to Type Bs, demonstrate enhanced biochemical and cardiovascular responses to stressful situations. These findings have led researchers to postulate that physiological reactivity may be one of the mechanisms through which Type A behavior confers coronary risk. The present study was designed to investigate physiological and psychological reactivity in Type A and Type B cardiac patients exposed to a cardiac catheterization. The effects of drugs (i.e., none versus beta-blockers and …

Tolerance, Bioenergetics And Biochemical Composition Of The Blue Crab, Callinectes Sapidus Rathbun, Exposed To The Water-Soluble Fraction Of South Louisiana Crude Oil., Shiao Yu Wang

LSU Historical Dissertations and Theses

The tolerance, bioenergetics, growth, molting frequency and biochemical composition of juvenile blue crabs, Callinectes sapidus, exposed to the water-soluble fraction of South Louisiana crude oil were determined during a 21-d exposure period. Blue crabs were highly tolerant to petroleum hydrocarbons; the LC50 was 3927 ppb on day 21. Rates of energy intake decreased with increasing hydrocarbon concentration. Although energy expenditure rates of crabs exposed to 2504 ppb were not significantly higher than that of control crabs, they were significantly higher than those of crabs exposed to 820 and 1476 ppb. The resulting decrease in scope for growth was thus due …

The Hepatotoxicity And Urinary Metabolites Of 2,4- And 2,6-Dimethylaniline In The Rat And Dog (Aromatic Amines)., Marcia L. Hardy

LSU Historical Dissertations and Theses

This study was designed to investigate the hepatotoxicity and urinary metabolites of 2,4- and 2,6-DMA in the dog and rat and the covalent binding of the two isomers in the rat as differences in metabolism may be related to the divergent hepatic responses. Male Beagles were orally dosed for 1 or 10 days with 2,6- or 2,4-DMA at 25 mg/kg. Male Fischer 344 rats were gavaged with 2,6- or 2,4-DMA at 25% of their respective LD50's (262.5 mg/kg; 117/mg/kg) for the same time period. The effects of phenobarbital (PB), 3-methylcholanthrene (3MC) and SKF-525A on the hepatotoxicity and metabolites of 2,4- …

Heritability Of Flowering In Sugarcane., Imran Mohammad

LSU Historical Dissertations and Theses

Heritability and other genetic effects for the date of first flowering, date of maximum flowering, average flowering date, percent flowering, pith and brix in sugarcane were estimated in a diallel cross experiment. A three year study indicated that the date of first flowering, date of maximum flowering, average flowering date, and percent flowering were highly heritable characters. The heritability estimates of pith and brix were very low and variable. Partitioning of total direct response in parental lines into average direct and average maternal genetic effects indicated that average maternal genetic effects of the early and late lines were larger in …

Sociologists And The Vietnam War: A Historical Document Analysis (Commodification, Post-Industrial)., Robert Earl Sanderson

LSU Historical Dissertations and Theses

Textbooks are important representative statements of certified and legitimated knowledge within an academic discipline, and the manner in which introductory sociology textbooks assess society reflect the power and sophistication of theories in discerning social patterns and structures. That the pivotal historical event of the Vietnam War and its implications for contemporary American social institutions was virtually omitted in our sample of one hundred-twenty textbooks raises critical issues for sociology. Content analysis of Vietnam War era textbooks (1954-1975) revealed 75% of the sample, divided among four major research orienting paradigms extant in sociology, ignored mention of the war and only the …

Spectroscopic Studies Of Bacterial Iron-Sulfur Proteins (Electron Paramagnetic Resonance, Magnetic Circular Dichroism)., Deborah Ellen Bennett

LSU Historical Dissertations and Theses

Iron-sulfur proteins play a vital role in metabolism; mediating such life-sustaining processes as aerobic and anaerobic respiration, nitrogen fixation, and photosynthesis. This work employs low temperature magnetic circular dichroism (MCD), electron paramagnetic resonance (EPR), and UV-visible spectroscopy to characterize the iron-sulfur clusters of the following bacterial proteins: Azotobacter vinelandii ferredoxinI, Thermus thermophilus ferredoxin, Escherichia coli nitrate reductase and the rubredoxin and ferredoxin from Clostridium pasteurianum. Novel 3Fe-xS clusters were identified in A. vinelandii FdI, T. thermophilus Fd, ferricyanide treated C. pasteurianum Fd, and E. coli nitrate reductase. The uniformity of the magnetic and electronic properties of these clusters in both …

The Christian Preacher As Poet: A Method For Exposition Of Narrative Portions Of Scripture Based On Aristotle's "Poetics"., William Sherman Phillips Jr

LSU Historical Dissertations and Theses

It is the thesis of this study that Aristotle's Poetics provides the basis for a method of exposition that is "distinctively appropriate" for preaching upon the narrative portions of Scripture. The relationship between Aristotelian poetics and narrative exposition of Scripture is examined in terms of the following two questions: (1) How does Aristotelian poetics meet the expository or interpretive need for narrative exposition of Scripture? (2) How does Aristotelian poetics meet the exhortatory or applicative need for narrative exposition of Scripture? The following arguments are made: (1) Aristotelian poetics provides the basis for a method of narrative exposition that unifies …

Locus-Specific Detection Of Hla-Dq And -Dr Antigens By Antibodies Against Synthetic N-Terminal Octapeptides Of The Β Chain, Thomas Deufel, Anne Grove, Hans Kofod, Åke Lernmark

Faculty Publications

Antibodies against synthetic peptides representing the class-II antigen HLA-DR and -DQ β chain N-terminal sequences were prepared in rabbits. The two octapeptides only share two amino acids and enzyme-linked immuno-assays showed the antisera only to bind to its own antigen. Both peptide antisera detected a 29 kDa component in immunoblots of Raji and AL-34 cell plasma membrane proteins separated by SDS gel electrophoresis. The binding of either N-terminal peptide antiserum was selectively inhibited only by the peptide used as antigen. Indirect immunofluorescence.analysis by flow cytofluorometry showed specific surface immunofluorescence in 1:100-1:1000 dilutions in lymphoblastoid and blood mononucleated cells. In the …

Water Quality Dynamics In Commercial Crawfish Ponds And Toxicity Of Selected Water Quality Variables To Procambarus Clarkii, Thomas Michael Hymel

LSU Historical Dissertations and Theses

Water quality in five southern Louisiana commercial crawfish (Procambarus clarkii and P. acutus acutus) ponds was monitored from November 1982 through May 1983. Two ponds were planted with rice (Oryza sativa) and three ponds had volunteer terrestrial and semi-aquatic vegetation as crawfish forage.

Water quality was poorest in November, April, and May when water temperatures exceeded 18"C. However, only dissolved oxygen (DO) attained concentrations low enough (<1.0 mg/liter) to be acutely toxic to crawfish. Free carbon dioxide (CO2) attained levels (12.0 mg/liter) that could potentially harm crawfish during periods of low DO (<2.0 mg/liter). The temperature, pH, free CO2, nitrate, total phosphorus, biochemical oxygen demand (BOD), chlorophyll a, total hardness, and total alkalinity did not differ significantly among rice ponds and ponds with volunteer vegetation. The DO, nitrite, total nitrogen, and chemical oxygen demand (COD) were highest in rice ponds (P<0.05). The soluble inorganic phosphorus (SIP) and conductivity were highest in ponds with volunteer vegetation (P<0.05).

Free CO2, SIP, conductivity, and total alkalinity levels were positively correlated with an increase in macrophytic biomass (P<0.10). Nitrite, total nitrogen, COD, BOD, turbidity, temperature and DO decreased with increased vegetative biomass. Crawfish catch was positively correlated with total ammonia, BOD, COD, and water temperature, and negatively correlated with total phosphorus, total nitrogen, SIP, total alkalinity, and DO.

The toxicity of hydroxyl and hydrogen ions (i.e., pH), ammonia, and nitrite to juvenile P. …

Modification Of Rice Flour And Its Potential Use In The Food Industry., Samir Sideek Alhusaini

LSU Historical Dissertations and Theses

Rice flour was modified with either 0.1, 1.0 and 5.0% acetic or succinic anhydride for 1, 6 and 18 hr under basic conditions. The pH was maintained above 7.0 using either sodium hydroxide or sodium carbonate. The results showed that modified rice flours had lower fat content as compared with the unmodified rice flour (control). The type of anhydride significantly influenced the fat content of rice flour. Ash content of rice flour increased significantly due to the anhydride concentrations and alkali type. Significant differences were also found in the protein content of modified rice flours due to the use of …

Assessment Of Dairy Product Quality Utilizing Bacterial Enumeration And Metabolite Detection., Jay Russell Bishop

LSU Historical Dissertations and Theses

A study was conducted to investigate the use of bacterial numbers and metabolites as estimators of the potential shelf-life of perishable dairy products, i.e., whole milk, skim milk and cottage cheese. The study was conducted in three phases. In the first phase, a method of impedance detection was performed at two incubation temperatures (18(DEGREES)C and 21(DEGREES)C), and its ability to estimate shelf-life of 100 commercially purchased milk samples compared to standard plate count (SPC), psychrotrophic bacteria count (PBC), modified psychrotrophic bacteria count (mPBC) and Mosely keeping quality test (MSPC). MSPC appeared to possess an adequate relationship to shelf-life (R = …

Response Transfer In Biofeedback Training., Lynn Pendarvis Clemow

LSU Historical Dissertations and Theses

The physiological effects and processes of biofeedback procedures are important issues in relaxation training. The purpose of this study was to assess the extent of cross-system generalization and the processes by which it may occur. Specifically, do different biofeedback tasks produce different patterns of response across systems and, are the physiological processes different for each biofeedback task, or are they similar processes in all tasks? Forty-eight volunteers participated in three one-hour sessions and randomly assigned to one of four groups as follows; (1) increase hand-temperature, (2) decrease frontalis-EMG, (3) decrease hand-temperature, and (4) control.

The Population Ecology And Nutrient Transport Of Gulf Menhaden In Fourleague Bay, Louisiana (Mortality, Growth, Feeding, Production, Migration)., Linda Ann Deegan

LSU Historical Dissertations and Theses

An ecological study of the young-of-the-year of three year-classes of gulf menhaden (Brevoortia patronus) was conducted from July 1981 to December 1983 in Fourleague Bay, Louisiana. This study documented gulf menhaden population ecology and the importance of gulf menhaden in the nutrient and energy balance of estuaries. Young-of-the-year gulf menhaden immigrated in winter and moved to tidal creeks and ponds, where they remained until midsummer. They then moved into open bays, where they remained until the fall. This migration pattern coincides with sequentially available, but spatially separate, productivity peaks in marsh and open bays. In the fall, they emigrated to …

Metal Ion, Protein, Phytic Acid Interactions., Elaine Thompson Champagne

LSU Historical Dissertations and Theses

Insight into the mineral, protein, phytate relationships in rice bran was gained by examining the solubility behavior of these components. Solubility profiles of the phosphorus and nitrogen components as a function of pH did not correspond, except in the pH 1.0-2.0 range. This is evidence that association between protein and phytate only occurred in this low pH range. Potassium, magnesium, and calcium solubilities as a function of pH corresponded to those of the phytic acid salts of these minerals. Soluble magnesium and potassium phytates were isolated on Sephadex G-25-50 and identified by ICP, confirming their presence in rice bran. The …

Molecular Studies Of Thamnophiine Snakes., Robin Lawson

LSU Historical Dissertations and Theses

Variation in alleles at gene loci encoding proteins was used to determine zoogeographic and evolutionary differentiation in thamnophiine snakes. Differentiation among populations within a species, among species within a genus, and among genera was investigated. In the southern banded water snake, Nerodia fasciata, analysis by F-statistics and genetic distances of allele frequencies indicated that extensive differentiation has occurred between those forms adapted to a saltwater environment (N. f. clarkii and N. f. compressicauda) and those adapted to a freshwater environment (N. f. fasciata, N. f. confluens, and N. f. pictiventris). Habitat disturbance is imputed as the causal agent in the …

The Biology Of Egg Production In The House Cricket, Acheta Domesticus L., Craig William Clifford

LSU Historical Dissertations and Theses

Oogenesis commenced on day 3 (day 0 = adult ecdysis) in Acheta domesticus L., which, based on degeneration of the flight muscles, was approximately when juvenile hormone was released. Starvation did not prevent the onset of oogenesis, although egg production was greatly reduced. Virgin females did not oviposit and the oviducts filled with eggs by day 15. Compaction appeared to be a factor limiting oogenesis. The digestive tract was compressed and feeding reduced, which might be the primary factors terminating oogenesis. The concentration of juvenile hormone esterase (JHE) did not change as virgins filled with eggs, which indicated that JHE …

Host Responses To The Phenolic-Glycolipid-1 Antigen Of Mycobacterium Leprae (Elisa, Leprosy, Epidemiology, Armadillo, Human)., Richard W. Truman

LSU Historical Dissertations and Theses

Antibody responses to the apparently species specific phenolic-glycolipid-1 (Phen-Gl-1) antigen of Mycobacterium leprae were examined in humans and armadillos using enzyme-linked immunosorbent assays (ELISA). Statistical definitions for the interpretation of positive and negative reactions were derived. A retrospective serological survey of armadillos indicated that leprosy in the wild armadillo is a naturally acquired zoonosis. Presently 12.5% of the armadillos in 2 parishes in south central Louisiana have detectable IgM antibodies to Phen-Gl-1. Approximately 2.7% of these histologically exhibit clinical disease. Antibodies were not detected in Florida armadillo sera. Variations in prevalence rates were noted, and may be due to environmental …

Individual Differences And Their Relation To Social Structure In Domestic Cats., Rena Durr Mister

LSU Historical Dissertations and Theses

Two groups of domestic cats with established social structures were tested for their response to novel stimuli in a variety of test situations. Clearly observable individual differences in responses were seen which were consistent over a series of test sessions and remained stable despite regular environmental disruptions. Individual differences in behavioral response were found not to be related to object dominance (food competition) or social dominance (freedom of movement in social encounters) unlike similar studies with social animals. No relationship was found in either group between rank in object dominance and rank in social dominance. Significant correlations were demonstrated between …

Metabolic Responses Of The Estuarine Gastropod Thais Haemastoma To Hypoxia (Energy Charge, Opine Dehydrogenase,Survival, Adaptation, Respiration)., Martin A. Kapper

LSU Historical Dissertations and Theses

The hypoxia tolerance (LC-50) of Thais haemastoma was inversely related to acclimation temperature but was not related to acclimation salinity between 10 and 30(DEGREES)C and 10 and 30('o)/ooS. T. haemastoma is moderately tolerant to anoxia, the LT-50 (time to 50% mortality) being 12-22 days. Oxyregulatory ability varies from poor to good, and varies inversely with temperature. The oxygen consumption rate was lower after 28 days exposure to hypoxic conditions than at full oxygen saturation at all salinities at 20 and 30(DEGREES)C. Oxygen consumption was low at 10(DEGREES)C regardless of ambient PO(,2). Oxyregulatory ability in T. haemastoma did not show acclimation …
