Quantifying Sustainability In Aquaculture Production., Rex Hall Caffey Jan 1998

Quantifying Sustainability In Aquaculture Production., Rex Hall Caffey

LSU Historical Dissertations and Theses

Despite increasing institutional focus in aquaculture, sustainability remains an amorphous and much debated concept. Little consensus has been identified on the issue beyond the general recognition that the concept should contain environmental, economic, and sociological considerations. This study addressed the specific, relevant question of whether politically diverse aquacuiture interests can collectively develop and agree on production-level goals and indicators of aquaculture sustainability. The research partitioned sustainability into its three subcategories: environmental, economic and social. This division facilitated the use of existing conventions of measurement and expression in each subcategory. Employing a modified Delphi technique, over 100 aquaculture stakeholders in the …

Apoptosis, Pcna, And P53, In Fundulus Grandis Fish Liver After In-Vivo Exposure To Mnng And 2-Af., Uriel Blas-Machado Jan 1998

Apoptosis, Pcna, And P53, In Fundulus Grandis Fish Liver After In-Vivo Exposure To Mnng And 2-Af., Uriel Blas-Machado

LSU Historical Dissertations and Theses

Dysfunction in homeostatic mechanisms of cell death and proliferation are considered to be important in carcinogenesis. The p53 gene has been implicated in the regulation of cell death and proliferation. The host response was measured through sequential immunohistochemical (IHC) detection of apoptosis, PCNA, and p53 in livers of Fundulus grandis fish exposed to MNNG or to 2-AF, two known carcinogens. Studies performed determined the stability of MNNG in saltwater, the suitability of different fixatives on IHC detection of apoptosis, PCNA-PC10, and p53 (various clones), and frequencies of expression of apoptosis, PCNA, and p53. A total of 996 fish specimens were …

All Blues: A Study Of African-American Resistance Poetry., Anthony Jerome Bolden Jan 1998

All Blues: A Study Of African-American Resistance Poetry., Anthony Jerome Bolden

LSU Historical Dissertations and Theses

Since the beginning of the twentieth century, critics of African-American poetry have disagreed vehemently about poetic form. Some, like J. Saunders Redding, for instance, have expressed skepticism about poetry based upon oral forms. Others, like Sterling Brown, have argued that a viable poetics can be developed from black expressive forms. This dissertation analyzes the debate over black poetic form and traces the development of modernist and postmodernist poetics that have been shaped by the specific contours of African-American vernacular culture. Yet this study is not merely formalistic. Although "All Blues" describes a blues aesthetic by examining intersexual relationships between the …

Molecular Systematics Of Selected Members Of The Black Basses, Genus Micropterus, With Concentration On The Spotted Bass (M. Punctulatus) Species Complex., Belinda Fuller Jan 1998

Molecular Systematics Of Selected Members Of The Black Basses, Genus Micropterus, With Concentration On The Spotted Bass (M. Punctulatus) Species Complex., Belinda Fuller

LSU Historical Dissertations and Theses

This study examined genetic relationships among selected populations of black basses. These centrarchid fishes, separated by both physical barriers (land formations) and distance, have shown varying degrees of differentiation, but retain many morphometric characters in common. Eight populations representing four taxa and geographical extremes in the genus Micropterus, with concentration on the spotted bass complex, were selected and evaluated for biochemical genetic characters. This study examined two species and two subspecies of spotted basses. The type species from Kentucky represented Micropterus punctulatus punctulatus; a population from Alabama represented M. p. henshalli. A Texas population, previously classified as conspecific with spotted …

A Validation Study Of The Assessment Of Dissimulation Scale Using Criminal And Civilly Committed Participants., Jill Suzanne Hayes Jan 1998

A Validation Study Of The Assessment Of Dissimulation Scale Using Criminal And Civilly Committed Participants., Jill Suzanne Hayes

LSU Historical Dissertations and Theses

Dissimulation malingering, unlike simulation malingering, refers to downplaying actual psychological difficulties in order to achieve secondary gain. Although several psychological tests have subscales designed to detect dissimulation, only the Assessment of Dissimulation Scale (ADS) has been specifically designed for this purpose. This screening instrument had limited usefulness, as it was validated only with college students. The purpose of this study was to determine whether the ADS was effective in detecting dissimulation in criminal and civilly committed populations which are likely to be the clinical targets for such a scale, and to establish a cut-off score on the ADS above which …

Effects Of Anesthesia And Potential Antispastic Agents In An Experimental Model Of Spasticity., Heather Colleen Mosser Jan 1998

Effects Of Anesthesia And Potential Antispastic Agents In An Experimental Model Of Spasticity., Heather Colleen Mosser

LSU Historical Dissertations and Theses

Spasticity is a common motor disorder in spinal cord injured-patients. Therapeutic agents used to treat the motor abnormalities exist but are often unsatisfactory. Tests of potential pharmacotherapies are routinely conducted in anesthetized intact or acutely spinal animals, conditions which do not accurately simulate the human situation. The purpose of this dissertation was to develop, validate and use the chronic spinal rat as a model of spasticity that closely approximates the human spastic syndrome to evaluate antispastic agents. The main goals of this research project were to: (1) demonstrate the development of spasticity in the chronic spinal rat; (2) determine effects …

Questions About Behavioral Function (Qabf): A Behavioral Checklist For Functional Assessment Of Aberrant Behavior., Theodosia Renata Paclawskyj Jan 1998

Questions About Behavioral Function (Qabf): A Behavioral Checklist For Functional Assessment Of Aberrant Behavior., Theodosia Renata Paclawskyj

LSU Historical Dissertations and Theses

Functional assessment is a tool in behavior therapy used to identify the functional relationships between a behavior of interest and the individual's environment. A functional assessment identifies variables that both occasion and maintain a particular behavior. Traditional functional assessment methodologies have relied on experimental techniques in which analog sessions are designed to mimic situations in the individual's environment. However, these techniques are time-consuming, require extensive training, and rely on the availability of numerous resources in the individual's setting. Development of a brief functional assessment checklist would circumvent these difficulties and make a significant contribution to applied behavioral psychology. The proposed …

Significance Of The Effect Of Nitrogen Application On The Engineered Bioremediation Of Crude Oil In A Salt Marsh., Paul Timothy Tate Jan 1998

Significance Of The Effect Of Nitrogen Application On The Engineered Bioremediation Of Crude Oil In A Salt Marsh., Paul Timothy Tate

LSU Historical Dissertations and Theses

The biodegradation of the crude oil in a salt marsh was monitored by tracking the decline of the ratio of various components in the crude oil to a stable marker, hopane. In studies of mesocosms, addition of nitrogen as ammonium nitrate resulted in more rapid biodegradation of the oil at 0.10 significance. In field plots, addition of nitrogen was found to not significantly increase the rate of oil degradation over the rate in the control plots. The degradation of the oil is best described by a first order decay equation. The kinetic rate parameter k was 0.0054/day in the control …

Functions Of Liminality In Literature: A Study Of Georges Bataille's "Le Bleu Du Ciel", Julien Green's "L'Autre", And Assia Djebar's "L'Amour, La Fantasia"., Malynda Strother Taylor Jan 1998

Functions Of Liminality In Literature: A Study Of Georges Bataille's "Le Bleu Du Ciel", Julien Green's "L'Autre", And Assia Djebar's "L'Amour, La Fantasia"., Malynda Strother Taylor

LSU Historical Dissertations and Theses

The term "liminality" originated in the work of two socioanthropologists, Arnold van Gennep and Victor Turner; it is descriptive of the middle phase in a rite of passage. Whereas the "betwixt and between" transitional pattern is temporary in tribal societies, it often becomes a way of life in the twentieth century. Although their projects differ greatly, Victor Turner's and Jacques Derrida's mutual interest in border spaces brings them both into this discussion. Some of the same phenomena described by the sociological term, liminality, is discussed philosophically as "undecidability" and "aporia." Liminality functions to link and to investigate three disparate twentieth-century …

Bioremediation Of Petroleum Hydrocarbons In Louisiana's Saltwater Marshes: Sediment Oxygen Demand Model., Won Sik Shin Jan 1998

Bioremediation Of Petroleum Hydrocarbons In Louisiana's Saltwater Marshes: Sediment Oxygen Demand Model., Won Sik Shin

LSU Historical Dissertations and Theses

Laboratory core studies were conducted to determine sediment oxygen demand (SOD) in petroleum hydrocarbon contaminated salt marshes. Natural degradation processes in salt marshes such as aerobic respiration, nitrification and sulfate reduction were investigated to quantify SOD. Oxygen demand in oiled/fertilized cores was greater than control and fertilized cores due to increased oxygen consumption by oil degradation and oxidation of reduced chemicals; sulfide and ammonium. SOD under non-flooded condition was greater than flooded condition due to an increased area of oxic-anoxic interface during air exposure. This may indicate that significant biodegradation of crude oil only occurs when the surface of the …

Association Of Environmental And Climatic Factors In The Epidemiology Of American Visceral Leishmaniasis In Northeast Brazil Using Remote Sensing And Geographical Information System Methods., Roland Alexander Thompson

LSU Historical Dissertations and Theses

This study associated climatic and environmental factors with the incidence of visceral leishmaniasis (calazar) in Northeast Brazil. Remote sensing (RS) techniques permitted evaluation of spatial and temporal landscape features to stratify the region and define the target population for this vector-borne disease. The Municipality of Caninde, Ceara, Brazil was divided into 873-- 2 x 2 km2 squares centered on coordinates from a Universal Transverse Mercator projection (scale 1:100,000, 1994) and geo-referenced with 2 Landsat T.M. (TM) scenes (September 26, 1976 and July 2, 1996). The assignment of squares into foothills, plains or city strata was based on vegetative categories determined …

Feeding Of Sciaenid (Pisces: Sciaenidae) Larvae In Two Coastal Lagoons Of The Gulf Of Mexico, Alberto Ocana-Luna, Marina Sanchez-Ramirez

Gulf and Caribbean Research

Stomach contents analyses showed that Leiostomus xanthurus (8.50-12.90 mm SL) had a wide trophic spectrum (15 food categories) with copepods and eggs of invertebrates as main components. In contrast, Micropogonias undulutus (6.65-12.20 mm SL) ingested only six food categories (copepods, eggs of invertebrates, crustacean nauplii, bamacle nauplii, amphipods and other crustaceans). There is an overlap of 73.2 to 83.0% in the diet of these two species. Bairdiella chrysoura (1.17-1.92 mm SL) fed primarily on juvenile pelecypods, crustacean nauplii, eggs of invertebrates, including gasteropods and copepods. Cynoscion nebulosus (1.50-2.42 mm SL) ingested juvenile pelecypods, copepods, crustacean nauplii, eggs of invertebrates and …

Effects Of The Burrowing Brittlestar, Microphiopholis Gracillima (Echinodermata: Ophiuroidea), On The Flux Of Lithium, An Inert Tracer, Across The Sediment-Water Interface, Timothy H. Shepherd, Stephen E. Stancyk, Timothy J. Shaw Jan 1998

Effects Of The Burrowing Brittlestar, Microphiopholis Gracillima (Echinodermata: Ophiuroidea), On The Flux Of Lithium, An Inert Tracer, Across The Sediment-Water Interface, Timothy H. Shepherd, Stephen E. Stancyk, Timothy J. Shaw

Gulf and Caribbean Research

Burrowing and ventilation activities of infaunal organisms have been shown to affect geochemical processes in sediments and at the sediment-water interface. Although burrowing brittlestars are dominant in many benthic environments, their role in these processes is poorly known. We tested the effect of the amphiurid brittlestar, Microphiopholis gracillima, on the flux of lithium ion from the sediment to the overlying water by using sediment cores with false bottoms for continuous flow of a Li+1-seawater solution. Brittlestars at densities of 300 and 600 individuals m-2 caused a twofold increase in the rate that Li was transported through …

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling Jan 1998

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling

Faculty Journal Articles

We explored the ability of older (60-80 years old) and younger (18-23 years old) musicians and nonmusicians to judge the similarity of transposed melodies varying on rhythm, mode, and/or contour (Experiment 1) and to discriminate among melodies differing only in rhythm, mode, or contour (Experiment 2). Similarity ratings did not vary greatly among groups, with tunes differing only by mode being rated as most similar. In the same/different discrimination task, musicians performed better than nonmusicians, but we found no age differences. We also found that discrimination of major from minor tunes was difficult for everyone, even for musicians. Mode is …

Evaluation Of Toxicity, Bioavailability And Speciation Of Lead, Zinc And Cadmium In Mine/Mill Wastewaters, Mujde Erten-Unal, Bobby G. Wixson, Nord Gale, Jerry L. Pitt

Civil & Environmental Engineering Faculty Publications

The toxicity of common compounds of lead, cadmium and zinc was evaluated in waters similar to that found in the world's largest lead producing area in Missouri. Static, acute toxicity tests were performed using fathead minnows (Pimephales promelas) and water fleas (Daphnia magna) respectively. Test organisms were subjected to varying amounts of sulfide, carbonate, chloride and sulfate salts of lead, zinc and cadmium mixed in hard, alkaline waters typical to this region. Median lethal concentrations were calculated using nominal versus measured metal concentrations. Measured metal concentrations included four different metal fractionation (extraction/filtration) techniques at different pH …

Can Patents Deter Innovation? The Anticommons In Biomedical Research, Michael Heller, Rebecca S. Eisenberg Jan 1998

Can Patents Deter Innovation? The Anticommons In Biomedical Research, Michael Heller, Rebecca S. Eisenberg

Faculty Scholarship

The "tragedy of the commons" metaphor helps explain why people overuse shared resources. However, the recent proliferation of intellectual property rights in biomedical research suggests a different tragedy, an "anticommons" in which people underuse scarce resources because too many owners can block each other. Privatization of biomedical research must be more carefully deployed to sustain both upstream research and downstream product development. Otherwise, more intellectual property rights may lead paradoxically to fewer useful products for improving human health.
