The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett Jan 1992

The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett

LSU Historical Dissertations and Theses

The United States, as other nation-states, claims legitimacy as an agency for the expression of the aspirations of its people. This political structure appeared as part of a historical process that implied a transfer of authority from ruling elite(s) to the public. However, U.S. foreign policy discourse evidences an incomplete relocation of authority. In matters of sovereignty and national interests, the policy establishment considers itself more capable of decisions than ordinary people. The establishment tends to view citizens as masses disinterested in and incapable of understanding vital decisions of the state. The policy establishment assumes the public's role is best …

Molecular Cloning, Expression And Site-Directed Mutagenesis Of A Complementary Dna Encoding Rabbit Muscle Fructose 6-Phosphate-1-Kinase., Jau-Yi Li

LSU Historical Dissertations and Theses

This dissertation contains three parts based on my research project which investigates three aspects of rabbit muscle phosphofructokinase (ATP: D-fructose-6-phosphate-1-phosphotransferase, EC 2.7.1.11; PFK). The first part reports the isolation and characterization of two full-length rabbit muscle PFK cDNAs. The DNA sequences of these two cDNAs (cDNA-A and cDNA-B) show an identical coding sequence but heterogeneous 5$\sp\prime$untranslated regions. cDNA-A is formed by removal of a 1.7 Kb upstream intron while cDNA-B retains the 3$\sp\prime$region of this intron. The second part describes the expression of the cDNA in several bacterial hosts. Recombinant rabbit muscle PFK has been expressed at a significant level …

Water cooled probes are used to obtain continuously gas temperatures and species concentrations within the kiln and afterburner, and existing facility instruments are also monitored. The kiln rotation rate is varied and turbulence air (air injected into the kiln to improve mixing) is added or turned off. Conditions at …


Taxonomic Treatment Of Indigofera L. (Fabaceae: Faboideae) In The New World., Alan Wayne Lievens Jan 1992

Taxonomic Treatment Of Indigofera L. (Fabaceae: Faboideae) In The New World., Alan Wayne Lievens

LSU Historical Dissertations and Theses

The current taxonomic study of Indigofera (Fabaceae) as it occurs in the New World has several aims. The first addresses taxonomic and nomenclatural issues related to North American taxa. Because such issues have not been well understood for many of these taxa at various ranks, a synopsis of all taxa known to be referable to North America is presented along with a thorough discussion of nomenclatural issues (including synonymy) for each. This discussion is initially placed within the framework of the species groups proposed by Rydberg in 1923. A preliminary cladistic analysis of these North American species groups is presented. …


Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian Jan 1992

Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian

LSU Historical Dissertations and Theses

Raw milk samples were analyzed to determine the bacteriological quality by the standard plate count (SPC), adenosine-5$\sp\prime$-triphosphate (ATP) assay, preliminary incubation counts, and the psychrotrophic bacteria count (PBC). In a comparison of SPC and ATP content, an overall correlation coefficient of 0.97 was found between the two methods. The correlations between ATP content and SPC of fresh raw milk samples at zero hour and after preliminary incubating these samples at 12.8 and 15.6$\sp\circ$C for 18 hours were.96,.97, and.97, respectively. The regression coefficients for all types of milk samples were highly significant ($P <$.01). High correlation coefficients demonstrated that the ATP measurement in combination with preliminary incubation practices could be a rapid technique for the determination of bacteriological quality of milk at receiving stations and milk processing plants. Median SPC for 175 fresh raw milk samples was 36,000/ml. The bioluminescence technique is reported previously to have a good correlation with SPC in the range of 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp{10}$ bacteria/ml. The commingled milk coming at the receiving stations sometimes have a bacterial count that is less than 1.0 $\times$ 10$\sp{5}$ bacteria/ml. A correlation coefficient of.87 was calculated between the SPC and ATP values for the overall data while lowering the SPC range from 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp4$ bacteria/ml. This range is more practical as a quick screening of raw milk at dairy processing facilities since 81 percent of all raw milk samples fell in this range. An equation (SPC = $-$1642213 + 6751(ATP)) was developed from the combined experimental data which could estimate the SPC of raw milk samples using their ATP content. Another phase of the experiment was to ascertain if the Petrifilm$\sp{\rm TM}$ technique could be effectively used in place of agar method to estimate PBC. The correlation coefficient between the Petrifilm$\sp{\rm TM}$ and the agar plate method for both the fresh and preliminary incubated raw milk samples was.99. A high linearity of relationship shows that one method can be substituted with the other. However, the Petrifilm$\sp{\rm TM}$ technique took longer than the usual time of 25 h to develop red colonies at 21$\sp\circ$C because of the slow reduction of the dye reagent triphenyl tetrazolium chloride (TTC) at this temperature.


Modeling Of Circulation And Transport In Terrebonne Bay, Louisiana And Its Implications For Oyster Harvesting Management., Ellen J. Prager Jan 1992

Modeling Of Circulation And Transport In Terrebonne Bay, Louisiana And Its Implications For Oyster Harvesting Management., Ellen J. Prager

LSU Historical Dissertations and Theses

Contamination of oyster-rich waters in south Louisiana by sewage-related wastes is believed to occur on a seasonally varying basis, and pose a serious threat to both human welfare and the local economy. Fluctuations in the meteorologic and oceanographic conditions in the region are believed to be responsible for the variability observed in bacterial concentrations. To gain a better understanding of the relationship between transport processes, environmental forcing, and the potential for contamination, a combined program of in situ measurements and numerical modeling techniques was conducted in the nearshore waters of Terrebonne Bay, Louisiana. A finite element model based on the …


A Multi-Criterion Transactional Model., Bradley Shawn O'Hara Jan 1992

A Multi-Criterion Transactional Model., Bradley Shawn O'Hara

Influences On The Instream Distribution Of Astyanax Fasciatus In A Small River In Costa Rica., Cecil Kelly Swing Jan 1992

Influences On The Instream Distribution Of Astyanax Fasciatus In A Small River In Costa Rica., Cecil Kelly Swing

LSU Historical Dissertations and Theses

The instream distribution of the tetra, Astyanax fasciatus, was investigated through approximately 700 hours of field observations in a small Costa Rican stream on the southwestern Pacific coast near Golfito. Individuals tended to remain in particular pools where they subsisted primarily on a diet of terrestrial insects. These fish were able to migrate, and only as many individuals stayed in any pool as could be sustained there by available food resources. Because the water intercepted insects fairly uniformly over its surface, the biomass of fish occupying any particular pool was proportional to its surface area (r$\sp2$ = 0.652). The amount …


Effects Of Vertebrate Herbivory On Louisiana Coastal Marshes., Katherine Lynn Taylor Jan 1992

Effects Of Vertebrate Herbivory On Louisiana Coastal Marshes., Katherine Lynn Taylor

LSU Historical Dissertations and Theses

The disturbances of herbivory, simulated "eat-outs" (clipping and removal of above-ground biomass), and burning were examined for their effect on total biomass, individual species abundance, and species richness in several different marsh communities. Herbivory significantly reduced the total community biomass of all the marshes studied. Simulated "eat-outs" reduced the total biomass of the freshwater marsh but had no persistent effect on the total biomass of either the oligohaline or mesohaline marshes of the Pearl River. Both the oligohaline and the mesohaline marshes were able to recover from a removal of above-ground biomass (simulated "eat-out") within two years. The freshwater marsh …


Interference, Management, And Growth Response Of Wild Poinsettia (Euphorbia Heterophylla L.) In Soybean., Teresa Summerford Willard Jan 1992

Interference, Management, And Growth Response Of Wild Poinsettia (Euphorbia Heterophylla L.) In Soybean., Teresa Summerford Willard

LSU Historical Dissertations and Theses

In field studies conducted in Louisiana in 1990 and 1991, area of influence, density, and duration of interference methodologies were used to evaluate wild poinsettia (Eupborbia heterophylla L.) interference in soybean (Glycine max (L.) Merr.). In 1990, soybean seed yield within 10 cm of wild poinsettia was similar to distances of 10 to 20 and 20 to 40 cm, but was less than that for distances greater than 40 cm from the weed. In contrast, soybean yields in 1991 growing within 10 cm of the weed were less than at greater distances. Weed interference resulted in a 9.4 and 18% …

This research studied dialogue journal writing, as it occurred between a teacher and twenty-one students in a French III high school. Results on attitude questionnaire indicated that dialogue journals helped students overcome their fear of the written form and increase their self-confidence and willingness to write. By demystifying the writing process, writing in their dialogue journals helped these students develop positive attitudes. The results on writing proficiency pre and post-tests indicated that students performed as well or better than students after four years of a foreign language in a high school setting or four semesters of college instruction. The dialogue …


Characterization Of Gentamicin Resistance In Enteric Bacteria Isolated From Pseudomys Scripta-Elegans From Commercial Turtle Farms., Michelle Anne Brassett Jan 1992

Characterization Of Gentamicin Resistance In Enteric Bacteria Isolated From Pseudomys Scripta-Elegans From Commercial Turtle Farms., Michelle Anne Brassett

LSU Historical Dissertations and Theses

Several genera of aminoglycoside resistant enteric bacteria were isolated from commercial turtle farms. Citrobacter freundii and Proteus vulgaris were the most prevalent organisms. Gentamicin resistance, measured by minimum inhibitory concentrations (MIC), ranged as high as 100 $\mu$g/ml. While resistance to other antibiotics was detected in gentamicin-resistant isolates, no correlation was observed between antibiotic resistance and plasmid content. Spontaneous mutation to gentamicin could not account for the high levels of gentamicin resistance found in the original isolates. Regions of chromosomal DNA encoding gentamicin resistance of 100 $\mu$g/ml were obtained from two Citrobacter freundii, two Proteus vulgaris, and two Salmonella enteritidis strains. …


The Use Of Hydrologically Altered Wetlands To Treat Wastewater In Coastal Louisiana., Andree Marie Breaux Jan 1992

The Use Of Hydrologically Altered Wetlands To Treat Wastewater In Coastal Louisiana., Andree Marie Breaux

LSU Historical Dissertations and Theses

Two major environmental problems currently affecting Louisiana are a high rate of coastal wetland loss and high levels of surface water pollution. The application of secondarily treated wastewater to wetlands is proposed as a means of dealing with these problems. The benefits of wetland wastewater treatment include improved surface water quality, increased accretion rates to balance subsidence, improved plant productivity, and decreased capital outlays for conventional engineering treatment systems. Wetland treatment systems can be designed and operated to restore deteriorating wetlands to previous levels of productivity. Hydrologically altered wetlands in the Louisiana coastal zone have been selected as appropriate for …

Re-Thinking Readings And Writing In The Study Of Literature., Mary Ann Doyle Jan 1992

Re-Thinking Readings And Writing In The Study Of Literature., Mary Ann Doyle

LSU Historical Dissertations and Theses

While the field of academic literary studies continues to engage in contested debate over defining and revising its curricula (Graff, 1987), teachers remain situated at the sometimes contradictory and often isolated intersections of theory and practice. Decisions made about writing in literature classes, selecting texts for course syllabi, and pedagogical style are most often negotiated at the level of the individual teacher, who may or may not be responding to an increasing incidence of departmental restructuring, recommendations, prohibitions, or political pressures. Though there is no scarcity of disagreements and accusations about what revisionary approaches 'mean', (Fieldnotes, Spring 1992), there is …


Synthesis Of Novel Metallocenes: Asymmetric Hydrogenation Catalysts To Conductive Polymers., Mark Steven Erickson Jan 1992

Synthesis Of Novel Metallocenes: Asymmetric Hydrogenation Catalysts To Conductive Polymers., Mark Steven Erickson

LSU Historical Dissertations and Theses

The goal of this research was to synthesize conductive polymers based on repeating ferrocene units. During the course of this study, the design of the conductive polymers evolved from the initial model based on "stacked" ferrocenes where ethano bridged cyclopentadienyl rings are linked by iron(II), to the latest ferrocene-diene model where ferrocene units were linked by double bonds. In the pursuit of these elusive monomers, attempts at their synthesis led down dead-end routes, even though new molecules were synthesized. Some of these dead-ends proved productive as in the synthesis of chiral titanocene derivatives. All the work reported in this dissertation …

Regional Comparative Advantage And Inefficiency In Production: Methodological And Empirical Issues., Barun Kanti Kanjilal

LSU Historical Dissertations and Theses

The general objective of this study was to provide a methodological framework for evaluating stochastic comparative advantage of a crop in a multi-region multi-crop framework and its link with inefficiency at the firm level. In the first stage, regional comparative advantage, defined in terms of relative profitability, was theoretically analyzed on the basis of a firm's behavior under uncertainty. The empirical application involved derivation of a comparative advantage index for major crops produced in different regions of Louisiana. The results revealed heterogenous survival potential of each crop across regions. Sugarcane was found to have comparative advantage over rice and soybeans …


Pistols And Politics: Planter And Plain Folk Relations In The Piney Woods South, The Florida Parishes Of Louisiana, 1810-1899. (Volumes I And Ii)., Samuel Claiborne Hyde Jr Jan 1992

Pistols And Politics: Planter And Plain Folk Relations In The Piney Woods South, The Florida Parishes Of Louisiana, 1810-1899. (Volumes I And Ii)., Samuel Claiborne Hyde Jr

LSU Historical Dissertations and Theses

The Florida parishes of Louisiana experienced a peculiar pattern of development. Following successive periods of English and Spanish domination and an armed insurrection resulting in the shortlived Republic of West Florida, the region stabilized under the control of delta parish planters. A fierce tradition of Jeffersonian republican values encouraged the plain folk to assert themselves politically during the 1830's and 1840's. Yet by employing a series of enemies common to southern whites, and by expanding their control over the means of access to market, the planters stifled the aspirations of the plain folk insuring white unity on the eve of …


A Novel Process For The Production Of Clinical Dextran., Doman Kim Jan 1992

A Novel Process For The Production Of Clinical Dextran., Doman Kim

LSU Historical Dissertations and Theses

A new process for the production of clinical (or controlled size) dextran was developed. This process is simpler, cheaper and more economical than traditional methods. It involves the use of a mixed culture fermentation with a dextranase producing strain (Lipomyces starkeyi ATCC 74054) and a dextransucrase producing strain (Leuconostoc mesenteroides ATCC 10830). The new process produced 84% (w/w) of theoretical yield clinical dextran with an average polydispersity between 1.2 and 1.5. The mechanism of clinical dextran formation is the competitive production of acceptors from newly formed dextran molecules by dextranase. The acceptors compete for the existing glucosyl portion of sucrose, …


Theatrical Intervention In The Aids Crisis: Performance, Politics, And Social Change., Cindy J. Kistenberg Jan 1992

Theatrical Intervention In The Aids Crisis: Performance, Politics, And Social Change., Cindy J. Kistenberg

LSU Historical Dissertations and Theses

This purpose of this study is to assess the efficacy of performance as a means of social change by focusing on performances that have arisen out of the AIDS crisis. Working from a cultural studies perspective, I attempt to delineate both the possibilities and limitations for this perspective on social change. By comparing the various forms these performances have taken, I offer an explanation as to how these forms inhibit or enhance the ability of a performance to challenge the dominant discourse on AIDS, and create and mobilize communities that can act in the fight against AIDS. I begin by …


Learning Horn-Clauses As Classification Rules For Relations., Mary Pamela Langley Jan 1992

Learning Horn-Clauses As Classification Rules For Relations., Mary Pamela Langley

LSU Historical Dissertations and Theses

Explanation-based learning (EBL) has been applied numerous times in many different domains using as much background knowledge as possible to guide the learning process. We design and implement a new EBL based algorithm called FORGE (FOrming Rules from Ground Explanations) which operates utilizing limited background knowledge. The input to the FORGE algorithm consists of examples and counterexamples of the target concept in the form of ordered tuples along with example tuples of base relations. This limited input is used to construct explanation trees which produce ground rules. These ground rules are then generalized and evaluated using simple cover counts. Different …
