The Production Of Triploid Oyster Larvae (Crassostrea Virginica (Gmelin)) In Louisiana., John Eric Supan Jan 1995

The Production Of Triploid Oyster Larvae (Crassostrea Virginica (Gmelin)) In Louisiana., John Eric Supan

LSU Historical Dissertations and Theses

Gonadal recycling of oyster broodstock, salinity effects during induction, and cytochalasin B (CB) dosage were investigated as factors affecting the production of triploid oyster larvae in Louisiana. These factors were studied at an oyster hatchery on Grand Isle, LA during 1992-1994 to help transfer triploid oyster technology to the Gulf region. Oyster broodstock were held nearshore in Caminada Bay, Louisiana and histologically analyzed between induced spawnings and during the winter of 1992-1993. Gametogenesis was analyzed qualitatively by developmental staging and quantitatively using mean gonad/body ratios (GBR) per section. The monthly percent occurrence of the developmental stages, as well as histological …

The Pueblo Region As A Linguistic Area: Diffusion Among The Indigenous Languages Of The Southwest United States., Catherine Bereznak Jan 1995

The Pueblo Region As A Linguistic Area: Diffusion Among The Indigenous Languages Of The Southwest United States., Catherine Bereznak

LSU Historical Dissertations and Theses

The goal of this dissertation is to investigate whether the Pueblo region of the Southwest United States is a legitimate linguistic area (LA). The Pueblo region has long been recognized as a cohesive culture area, but an in-depth examination of the Pueblo region as a linguistic area has not previously been done. Because a linguistic area is by definition an area in which linguistic features have spread through diffusion, traits which are widespread for other reasons (e.g., genetic inheritance or independent parallel development) must be eliminated as evidence for a Pueblo LA. The methodological approach which I adopt emphasizes the …

Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole Jan 1995

Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole

LSU Historical Dissertations and Theses

Interest in dysfunctional consumption behaviors, such as compulsive buying, is a fairly recent development in the marketing literature. The purpose of this dissertation was to develop and test a theoretical model of the structural relationships among potential antecedents of compulsive buying behavior. In this dissertation, an extensive literature review identified several key constructs in the development of compulsive buying. These constructs include a family environment factor (parental influence), obsessive-compulsive trait, trait self-esteem, generalized anxiety, impulsive behavior, and anxiety reduction through shopping motivations. Seven studies were performed, including pretest and final studies with national non-student samples. Using LISREL, a structural model …

A Comparison Of Preference Responses Of White And African-American Students To Musical Versus Musical/Visual Stimuli And Their Relationship To Same- And Other Group Attitudes., Steven Joseph Morrison Jan 1995

A Comparison Of Preference Responses Of White And African-American Students To Musical Versus Musical/Visual Stimuli And Their Relationship To Same- And Other Group Attitudes., Steven Joseph Morrison

LSU Historical Dissertations and Theses

It was the purpose of this study to examine the role of same- and other-group identification in musical preference decision-making and the relationship between preference decisions and attitude-oriented responses to hypothetical social encounters with same- and other-group members. Subjects were African-American (n = 189) and white (n = 280) sixth, seventh and eighth grade music students. To measure musical preference, each subject responded along a 9-point Likert scale to 10 instrumental music excerpts, five performed by African-American jazz artists and five performed by white jazz artists. The examples were presented according to one of three conditions: (1) music only, (2) …

The Molecular And Morphological Systematics Of Subfamily Epidendroideae (Orchidaceae)., Malcolm Ray Neyland Jan 1995

The Molecular And Morphological Systematics Of Subfamily Epidendroideae (Orchidaceae)., Malcolm Ray Neyland

LSU Historical Dissertations and Theses

The current project undertakes the first molecular-based phylogenetic study of subfamily Epidendroideae (Orchidaceae). Approximately 1,200 nucleotide bases (from the 3$\sp\prime$ half of the ndhF chloroplast gene) for 34 orchid taxa, and a lilioid monocot, Clivia miniata, (Amaryllidaceae) were subjected to phylogenetic analysis using parsimony methods. Oryza sativa (Poaceae), a nonlilioid monocot was designated as outgroup. Using unweighted ndhF sequences, the strict consensus cladogram of 531 most-parsimonious trees supports the hypothesis that the large subfamily Epidendroideae is monophyletic, with Listera (Neottieae) as sister. Although subtribal-level relationships in subfamily Epidendroideae ate well resolved in this analysis, tribal-level relationships are resolved poorly. A …

Changes Of Amylases And Carbohydrates In Sweetpotatoes During Storage And Their Effects On Viscosity Of Sweetpotato Puree., Xiangyong Liu Jan 1995

Changes Of Amylases And Carbohydrates In Sweetpotatoes During Storage And Their Effects On Viscosity Of Sweetpotato Puree., Xiangyong Liu

LSU Historical Dissertations and Theses

A critical problem associated with the production of sweetpotato puree is the inconsistency of final product. Two possible factors, amylase activity and carbohydrate content in sweetpotatoes during storage, were investigated. It was found that $\alpha$- and $\beta$-amylase activities do not significantly change during storage, and have no significant effects on viscosity of sweetpotato puree. The inconsistent products in sweetpotato puree processing are mostly due to the change of alcohol insoluble solids (AIS) in sweetpotatoes during storage. The decrease of AIS is partially due to respiration that converts starch into CO$\sb2$ and H$\sb2$O. A new bio-processing method was proposed to improve …

Myoglobin And Lipid Stability Of Meat And Liposome Model Systems With Modified Atmosphere Packaging., Nai-Yun Huang Jan 1995

Myoglobin And Lipid Stability Of Meat And Liposome Model Systems With Modified Atmosphere Packaging., Nai-Yun Huang

LSU Historical Dissertations and Theses

The influences of lipid peroxidation and pigment autoxidation in beef and liposome model systems were examined in modified atmosphere packaging containing oxygen (O$\sb2).$ Ground beef of 75 and 90% lean were packaged in 80% nitrogen (N$\sb2){:}20\%$ carbon dioxide (C$\sb2)$ for distribution and storage atmospheres were exchanged for 80% $\rm O\sb2{:}20\%\ CO\sb2$ at 15, 18, 20, 22, 25, 27 or 29 days postpackaging before retail display. On the same postpackaging day, samples from longer gas exchange, but shorter display times had lower lipid oxidation, psychrotrophic growth, metmyoglobin formation, discoloration and odor scores when compared with samples from shorter gas exchange times …

Management Of Bollworm, Helicoverpa Zea (Boddie), And Tobacco Budworm, Heliothis Virescens (F.), With Transgenic Bt Cotton Genotypes, Microbial Insecticides And Conventional Insect Resistance Traits In Cotton., Charles Andrew White

LSU Historical Dissertations and Theses

Studies were conducted to determine the effectiveness of Bacillus thuringiensis (Bt) insecticides and transgenic Bt cotton in controlling the bollworm (BW), Helicoverpa zea (Boddie) and tobacco budworm (TBW), Heliothis virescens (F.), complex. Laboratory tests indicated that rates $\ge$1.17 liters (form)/ha caused TBW mortality significantly higher than the untreated control 2 hours after treatment (HAT). Dipel ES$\sp\circler$ at 4.68 liters (form)/ha and Condor OF$\sp\circler \ge$ 0.58 liters (form)/ha caused significantly higher TBW mortality than the untreated control at 72 HAT. TBW mortality levels did not significantly increase as Dipel ES$\sp\circler$ or Condor OF$\sp\circler$ dosage rates increased. Results of a persistence study …

Popular Theatre In Eighteenth- And Nineteenth-Century Vienna: Stage Characters And Performance Sites., Gregory John Dykhouse Jan 1995

Popular Theatre In Eighteenth- And Nineteenth-Century Vienna: Stage Characters And Performance Sites., Gregory John Dykhouse

LSU Historical Dissertations and Theses

This dissertation pursues a relationship between the changing venues of the Viennese popular theatrical tradition, or Wiener Komodie, and the evolution of the comic figure from the performances of Josef Anton Stranitzky (1676-1726) to Johann Nestroy (1801-1862). This study follows a procedure of reconstructing the major venues associated with the Viennese comic tradition and analyzing the changes in the depiction of the comic character as they relate to the changes in the venues. This presentation of Viennese performance sites and stage characters ultimately explores the relationship between physical space (object of material culture, such as a purpose-built theatre) and theatrical …

Habitat Use, Movement, And Production Ecology Of The Crayfish Procambarus Vioscai, Christopher David Barcza Dec 1994

Habitat Use, Movement, And Production Ecology Of The Crayfish Procambarus Vioscai, Christopher David Barcza

LSU Historical Dissertations and Theses

I conducted three studies during the year of 1993 in order to investigate the ecology of the crayfish Procambarus vioscai in the streams of the Kisatchie National Forest. The first study was designed to determine the factors that effect the microdistribution of this crayfish. A direct and positive relationship between the variation in leaf accumulation and crayfish biomass in a location was observed in the study streams. Laboratory observations of the behavior of the crayfish associated with leaf litter and a regression model for structure volume versus crayfish biomass indicated that exploitation of leaf accumulations by P. vioscai is a …

Cloning And Functional Characterization Of Lcr-F1: A Bzip Transcription Factor That Activates Erythroid-Specific, Human Globin Gene Expression, John J. Caterina, David Donze, Chiao Wang Sun, Dominic J. Ciavatta, Tim M. Townes Jun 1994

Cloning And Functional Characterization Of Lcr-F1: A Bzip Transcription Factor That Activates Erythroid-Specific, Human Globin Gene Expression, John J. Caterina, David Donze, Chiao Wang Sun, Dominic J. Ciavatta, Tim M. Townes

Faculty Publications

DNase I hypersensitive site 2 (HS 2) of the human β-globin Locus Control Region (LCR) directs high level expression of the β-globin gene located 50 kilobases downstream. Experiments in cultured cells and in transgenic mice demonstrate that duplicated AP1-like sites in HS 2 are required for this powerful enhancer activity. A cDNA clone encoding a basic, leucine-zipper protein that binds to these sites was isolated and designated Locus Control Region-Factor 1 (LCR-F1). This protein is a member of a new family of regulatory factors that contain a 63 amino acid 'CNC domain' overlapping the basic region. This domain is approximately …

Multiple Elements In Human Β-Globin Locus Control Region 5′ Hs 2 Are Involved In Enhancer Activity And Position Independent, Transgene Expression, John J. Caterina, Dominic J. Ciavatta, David Donze, Richard R. Behringer, Tim M. Townes Mar 1994

Multiple Elements In Human Β-Globin Locus Control Region 5′ Hs 2 Are Involved In Enhancer Activity And Position Independent, Transgene Expression, John J. Caterina, Dominic J. Ciavatta, David Donze, Richard R. Behringer, Tim M. Townes

Faculty Publications

The human β-globin Locus Control Region (LCR) has two important activities. First, the LCR opens a 200 kb chromosomal domain containing the human ε-, γ- and β-giobin genes and, secondly, these sequences function as a powerful enhancer of ε-, γ- and β-globin gene expression. Erythrold-specific, DNase I hypersensitive sites (HS) mark sequences that are critical for LCR activity. Previous experiments demonstrated that a 1.9 kb fragment containing the 5′ HS 2 site confers position-independent expression in transgenic mice and enhances human β-giobin gene expression 100-fold. Further analysis of this region demonstrates that multiple sequences are required for maximal enhancer activity; …

The Value Of Salt Marsh Edge Vs Interior As A Habitat For Fish And Decapod Crustaceans In A Louisiana Tidal Marsh, G. W. Peterson, R. Eugene Turner

Faculty Publications

Flume nets of various lengths and a 3-m seine were used to sample the fishes and macrocrustaceans using a flooded Louisiana salt marsh and the adjacent tidal creek. The experiment allowed for species-specific comparisons of the flooded marsh at the creek edge versus the interior. Of the 37,667 organisms collected in flume nets from January through November 1989, 89% were decapods (nine species) and 11% were fish (29 species). An additional 18,539 organisms (75% decapods and 25% fish) were collected from concurrent seine samples taken from July through November. Comparison of catches among different flume lengths and low tide versus …

Faculty Publications

The coronavirus strain HECV‐4408 was isolated from diarrhea fluid of a 6‐year‐old child with acute diarrhea and propagated in human rectal tumor (HRT‐18) cells. Electron microscopy revealed coronavirus particles in the diarrhea fluid sample and the infected HRT‐18 cell cultures. This virus possessed hemagglutinating and acetylesterase activities and caused cytopathic effects in HRT‐18 cells but not in MDBK, GBK and FE cells. One of four S‐specific monoclonal antibodies reacted in Western blots with HECV‐4408, BCV‐L9 and BCV‐LY138 but not with HCV‐OC43, and two reacted with BCV‐L9 but not with HECV‐4408, BCV‐LY138 and HCV‐OC43. One S‐specific and two N‐specific monoclonal antibodies …

Associations Of Methanotrophs With The Roots And Rhizomes Of Aquatic Vegetation, G. M. King Jan 1994

Associations Of Methanotrophs With The Roots And Rhizomes Of Aquatic Vegetation, G. M. King

Faculty Publications

Results of an in vitro assay revealed that root-associated methane consumption was a common attribute of diverse emergent wetland macrophytes from a variety of habitats. Maximum potential uptake rates (V(maxp)) varied between about 1 and 10 μmol g (dry weight)-1 h-1, with no obvious correlation between rate and gross morphological characteristics of the plants. The V(maxp) corresponded to about 2 x 108 to 2 x 109 methanotrophs g (dry weight)-1, assuming that root-associated methanotrophs have cell- specific activities comparable to those of known isolates. V(maxp) varied seasonally for an aquatic grass, Calamogrostis canadensis, and for the cattail, Typha latifolia, with …

Comparative Hepatic Oxidative Biotransformation In Domestic Avian Species., June Lynn Sutherlin

LSU Historical Dissertations and Theses

This study characterized the oxidative biotransformation capacity of the hepatic cytochrome P-450 system of selected avian species representing the Galliformes (chicken, turkey and Japanese quail) and Anseriformes (goose, Pekin duck, Khaki Campbell duck, and Muscovy duck) orders. Two objectives were addressed; first, important biotransformation pathways were evaluated in economically major and minor food-producing avian species to provide a framework on which to base drug approval decisions in these species. Second, the potential use of the selected species as sentinel organisms utilizing cytochrome P-450 induction as a biomarker of environmental chemical exposure was evaluated. The male rat was utilized for the …

Effects Of Dietary Boron In Rats Fed A Vitamin D-Deficient Diet, J. N. Dupre, M. J. Keenan, M. Hegsted, A. M. Brudevold

Faculty Publications

Although boron has long been known to be a required nutrient for plants, it was not until recently that there was any suggestion of a nutritional requirement for animals and humans. Addition of boron to the diet of vitamin D-deficient chicks indicated that boron may play a role in animal nutrition. Studies with rats have demonstrated that supplemental dietary boron has most marked effects when the diet is deficient in known nutrients. We observed higher apparent-balance values of calcium, magnesium, and phosphorus for rats fed a vitamin D-deprived diet with dietary supplemental boron (2.72 ppm), than for rats fed the …

Murderous Historian: Henry Adams, Modernity, And The Problem Of Subjectivity. (Volumes I And Ii)., Martha Moseley Regalis

LSU Historical Dissertations and Theses

This study traces Henry Adams's evolution from an enlightenment historian to a prescient postmodern theorist, and explores how he came to regard his own intellectual history as paradigmatic of the arc of subjectivity in the West from the Middle Ages to Nietzsche and Bergson. Adams was a self-conscious philosophical nominalist, and he believed that his radical doubts about the capacity of language for embodying meaning had their origin in medieval nominalism. Adams found the seeds of modernity and the problem of subjectivity which were the focus of his own musings on the nature of the self and history in Abelard …
