Interrelationships Between Mitochondrial Function, Maximal Oxygen Consumption, Running Economy, And Diet In Elite Male And Female Runners, Ryan Peyton Mcmillan

LSU Master's Theses

The relationships between maximal oxygen consumption (VO2max), mitochondrial function and running economy were investigated in a population of twenty-one endurance trained males and females (range=18-54 yrs). The purposes of this study were: 1) to determine whether mitochondrial oxidative capacity, as defined by the maximal activities of citrate synthase (CS), cytochrome c oxidase (COX), and beta-hydroxyacyl-CoA dehydrogenase (BHAD), is a significant determinant of maximal oxygen consumption in endurance trained men and women, and 2) to observe the relationship between maximal oxygen uptake and running economy in the same population. Muscle biopsy samples were taken from the vastus lateralis prior to a …

New Programs In The Old Asylum: The Deinstitutionalization Of Long-Term Psychiatric Hospital Patients In Argentina, Erica Dillon

LSU Master's Theses

Large psychiatric hospitals with inpatients interned for decades are still the norm in Argentina, where deinstitutionalization and community-based mental health care is almost inexistent. This thesis focuses on some changes taking place in a centenary psychiatric hospital in Buenos Aires province: the externación of long-term psychiatric patients through new programs planned and run from inside the institution by health professionals compromised in making a change in the old asylum. Can long-term inpatients with serious mental illness such as schizophrenia leave the asylum and integrate in the society having a recovered life? Do the new externación programs make this possible? What …

Smc3 Knockdown Triggers Genomic Instability And P53-Dependent Apoptosis In Human And Zebrafish Cells., Giancarlo Ghiselli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: The structural maintenance of chromosome 3 (SMC3) protein is a constituent of a number of nuclear multimeric protein complexes that are involved in DNA recombination and repair in addition to chromosomal segregation. Overexpression of SMC3 activates a tumorigenic cascade through which mammalian cells acquire a transformed phenotype. This has led us to examine in depth how SMC3 level affects cell growth and genomic stability. In this paper the effect of SMC3 knockdown has been investigated. RESULTS: Mammalian cells that are SMC3 deficient fail to expand in a clonal population. In order to shed light on the underlying mechanism, experiments …

Tracing Nitrogen In Volcanic And Geothermal Volatiles From The Nicaraguan Volcanic Front, James A. Walker, L.J. Elkins, T.P. Fischer, D.R. Hilton, Z.D. Sharp, S. Mcknight

Faculty Articles, Papers, and Other Scholarship

We report new chemical and isotopic data from 26 volcanic and geothermal gases, vapor condensates, and thermal water samples, collected along the Nicaraguan volcanic front. The samples were analyzed for chemical abundances and stable isotope compositions, with a focus on nitrogen abundances and isotope ratios. These data are used to evaluate samples for volatile contributions from magma, air, air-saturated water, and the crust. Samples devoid of crustal contamination (based upon He isotope composition) but slightly contaminated by air or air-saturated water are corrected using N2/Ar ratios in order to obtain primary magmatic values, composed of contributions from upper mantle and …

Impacts Of Red Imported Fire Ants (Solenopsis Invicta Buren) On Native Faunal Communities In Two Pine-Dominated Forests, Lee A. Womack

LSU Master's Theses

Impacts red imported fire ants (RIFA) exert on native faunal communities were monitored in two pine-dominated ecosystems in Louisiana. After suppression of established RIFA populations with Amdro®, cotton mice (Peromyscus gossypinus), herpetofaunal, ground-dwelling invertebrate, Lycosidae, and non-target ant communities were compared between untreated-control and treated plots with respect to possible ecological impacts of RIFA on these communities. Efficacy of Amdro® (A. I. 0.7% hydramethylnon) was tested at Alexander State Forest and Sandy Hollow WMA, and was found to be effective at both sites for 99-42.3% and 97-48%, respectively, suppression of RIFA on treated plots, for three to seven months, with …

Three Theories Of Substantive Due Process, Daniel O. Conkle

Articles by Maurer Faculty

Substantive due process is in serious disarray, with the Supreme Court simultaneously embracing two, and perhaps three, competing and inconsistent theories of decisionmaking. The first two theories, historical tradition and reasoned judgment, have explicit and continuing support in the Court's decisions. Under the theory of historical tradition, substantive due process affords presumptive constitutional protection only to liberties that are "deeply rooted in this Nation's history and tradition." By contrast, the theory of reasoned judgment is far more expansive, permitting the Court to identify rights independently, through a process that amounts to philosophical analysis or political-moral reasoning. The third theory, evolving …

Experimental Analysis Of Mechanical Seal Design With Enhanced Thermal Performance, Ainsworth Gidden

LSU Master's Theses

For industries that use pumps and mixers in their process operations, it is of paramount importance to control the leakage from these equipments. The leakage presents safety hazards and economic loss. It is widely believed that the majority of downtime associated with a pump or a mixer is the result of a mechanical seal failure. Therefore, it is important for these industries to have a mechanical seal that is a reliable performer and enables a longer operational life than what exist in the market at present. The aim of this research was to design and test a mating ring with …

Lashing Reason To The Mast: Understanding Judicial Constraints On Emotion In Personal Injury Litigation, Jody L. Madeira

Articles by Maurer Faculty

Arguing from the premise that personal injury plaintiffs and injury evidence do not taint proceedings by encouraging jurors to adjudicate based on emotion rather than evidence, this article reviews and challenges judicial attempts to constrain jurors' emotive responses to an injured plaintiff in three areas of personal injury litigation: voir dire, admissibility of evidence, and restrictions on damages arguments and assessment. The judicial abhorrence of sympathy as a ground for substantive decision making during some phases of the trial clashes with judicial tolerance of the emotion during others, giving rise to a pattern of sympathy in, sympathy out where the …

A Comparative Study Of Household Demand For Meats By U.S. Hispanics, Carlos Ignacio Garcia

LSU Master's Theses

The general objective of this research project was to study the consumption behavior of U.S. Hispanics for meat products. A comprehensive review of literature on the studies of U.S. Hispanic consumers was performed by means of a systematic survey; different sources of information useful in studying Hispanic consumers were documented. The simultaneous increase in population and income of Hispanics in the United States is attractive to food companies, and makes more relevant the study of their consumer behavior patterns for discovering future market opportunities. Censored incomplete demand systems of the LinQuad form were used for recognizing the consumption patterns by …

The Effect Of Music Tempo On Movement Responses Of Preschool Children, Melanie Woods Alexander

LSU Master's Theses

The purpose of this study was to examine the effect of tempo on movement responses of children ages one to three. For two weeks, 17 children between the ages of 22 and 36 months were videotaped twice per week to observe and measure their movement responses to fast and slow musical stimuli. During these sessions, the children were videotaped in their classrooms, engaged in either free play or in a quiet group activity. The videotaped sessions were then analyzed using a Motor Observation Form. Once all of the tapes had been viewed and scored, overall percentages of movement and no …

Information Analysis Of Dna Sequences, Riyazuddin Mohammed

LSU Master's Theses

The problem of differentiating the informational content of coding (exons) and non-coding (introns) regions of a DNA sequence is one of the central problems of genomics. The introns are estimated to be nearly 95% of the DNA and since they do not seem to participate in the process of transcription of amino-acids, they have been termed “junk DNA.” Although it is believed that the non-coding regions in genomes have no role in cell growth and evolution, demonstration that these regions carry useful information would tend to falsify this belief. In this thesis, we consider entropy as a measure of information …

Petrological And Geochemical Investigations Of Deep Sea Turbidite Sands In The Pandora And Moresby Troughs: Source To Sink Papua New Guinea Focus Area, Luke Jeremiah Patterson

LSU Master's Theses

The Moresby and Pandora Troughs of the northern Coral Sea are components of the deep-sea depositional system that is the ultimate sink for the Source to Sink Papua New Guinea (PNG) Focus Area. Cores collected from the R/V Melville during March-April 2004 reveal marine volcaniclastic and terrigenous turbidites deposited in these troughs during the Quaternary. Constraining the spatial, temporal, and provenance characteristics for these terrigenous sands through mineralogical, chemical, and textural analysis is the primary focus of this study. All cores contain thinly-bedded sandy turbidite packages interlayered with hemipelagic marls and typical centimeter-to-meter-thick turbidite sequences. The Moresby Trough core JPC22 …

Nutrient-To-Cost Comparisons Of Daily Dietary Intake, Food Security Status, And Body Mass Index In Female Food Stamp Recipients Residing In Southeast Louisiana, Shanna Lundy

LSU Master's Theses

Diets are typically poorer and risk of chronic disease is greatest in low-income populations. A relationship has been established in the literature between food costs and diet quality, where lower cost diets are generally those of the poorest quality. Food group intake, energy/nutrient intake, and diet cost were assessed in 64 female food stamp recipients in Southeast Louisiana. From one 24-hour dietary recall collected at the beginning of the monthly resource cycle (Day 1) and one at the end (Day 2), nutrient intakes and diet costs were able to be analyzed between different time frames. Participants were divided among food …

The Effects Of Contextual Interference On The Acquisition, Retention, And Transfer Of A Music Motor Skill Among University Musicians, Leslie Paige Rose

LSU Doctoral Dissertations

The contextual interference hypothesis holds that simple motor skill tasks are best learned when practiced under blocked, or repetitive conditions, but that retention and transfer are best accomplished when the skill has been practiced in varied conditions. The purpose of this study was to measure the effects of contextual interference practice conditions on the acquisition, retention, and transfer of a complex task—right hand lead percussion sticking technique among university musicians. All participants (N = 120) demonstrated rhythmic competency for the task, and were necessarily unable to perform the sticking technique with accuracy at the start of treatment. Three treatment groups …

Biopolitics Or The Legislation Of Life: A Foucauldian Analysis, Marina Basu

LSU Master's Theses

Michel Foucault uses the term biopolitics to highlight the focus on life that is at the center of contemporary politics. Biopower or biopolitics is the maximization of life through various regulatory apparatuses that monitor, modify, and control life processes. I elucidate and exemplify Foucault's framework in order to show how the medical discourse exercises a certain kind of power over bodies in the name of health. My argument is that through the mechanisms of biopower, the juridico-medical discourse simultaneously makes pregnancy into an object of study and the pregnant woman into a subject of power. With the help of a …

Green Hydrogen: Site Selection Analysis For Potential Biomass Hydrogen Production Facility In The Texas-Louisiana Coastal Region, Bryan Michael Landry

LSU Master's Theses

Hydrogen and the “Hydrogen Economy” are increasingly becoming buzzwords in discussions regarding future U.S. energy scenarios. Hydrogen energy offers a multitude of economic and environmental advantages over the current world energy structure. Despite this attention, there have been very few geographical studies of a possible transition to a hydrogen system. Even these studies have been limited in scope to demand-side analyses. This thesis attempts to rectify this situation by broadening the scope of geographical studies of hydrogen through the analysis of supply-side scenario. This study is a site selection model for a biomass hydrogen facility in the Gulf Coast of …

Albert Camus's Meditative Ascent: A Search For Foundations In The Plague, Brian James Blanchard

LSU Master's Theses

Albert Camus's concept of absurdity states that human existence is fundamentally chaotic and meaningless. Despite this appraisal of existence, Camus tirelessly campaigned for human rights at a time when many intellectuals ignored the atrocities perpetrated by ideological compatriots. Scholars admire Camus's courage and foresight, but few have attempted to systematically examine Camus's philosophical development of values. Eric Voegelin argues that Camus's writings take the form of a philosophical meditation in which Camus conducted an analysis of existence through the medium of fictional creation. This meditation, which Voegelin likens to a Platonic periagoge, allowed Camus to establish a foundation of values …

Why Kelo Is Not Good News For Local Planners And Developers, Daniel H. Cole

Articles by Maurer Faculty

When the Supreme Court announced its 2005 decision in Kelo v. City of New London, few legal scholars were surprised at the outcome, which was premised on precedents extending back to the middle of the 19th century. Legal scholars were surprised, however, by the intense political reaction to Kelo (fueled substantially by Justice O'Connor's hyperbolic dissent), as property-rights advocates, legislators (at all levels of government), and media pundits assailed the ruling as a death knell for private property rights in America.

Kelo's combination of relative legal insignificance and high political salience makes it an interesting case study in cross-institutional dynamics, …

Links Between Environmental Mercury, Special Education, And Autism In Louisiana, Jessica Rury

LSU Master's Theses

The number of children born every year with neurological disorders is increasing and some of this increase may be attributed to mercury exposure. Pregnant women ingest contaminated fish, which transfers high mercury concentrations to the unborn fetus. This exposure may result in methyl mercury buildup in the brain of the unborn fetus. Symptoms ranging from minor to severe may be observed as special educational needs in school systems. These include learning disorders, developmental delays, and autism. Louisianans are especially susceptible to mercury contamination because fish and shellfish are a major portion of their cultural diet. This study, through the use …

A Semiparametric Assessment Of Export-Led Growth In The Philippines, Lorna E. Amrinto

LSU Master's Theses

This study contributes to the literature on the export-led growth (ELG) hypothesis by adopting a semiparametric approach under two levels of temporal aggregation to investigate the ELG hypothesis in the Philippines. To assess the impact of model specification on the ELG hypothesis, parametric and semiparametric ECMs are estimated using Philippine annual and quarterly data on GDP, exports, exchange rates and gross fixed-capital formation, focusing on the role of exchange rates. The causal relationship between exports and economic growth is examined using the Granger-causality procedure. It can be concluded that for the Philippines, the ELG hypothesis is (a) sensitive to model …

Instantaneously Trained Neural Networks With Complex And Quaternion Inputs, Adityan V. Rishiyur

LSU Master's Theses

Neural network architectures such as backpropagation networks, perceptrons or generalized Hopfield networks can handle complex inputs but they require a large amount of time and resources for the training process. This thesis investigates instantaneously trained feedforward neural networks that can handle complex and quaternion inputs. The performance of the basic algorithm has been analyzed and shown how it provides a plausible model of human perception and understanding of images. The motivation for studying quaternion inputs is their use in representing spatial rotations that find applications in computer graphics, robotics, global navigation, computer vision and the spatial orientation of instruments. The …

Enhanced Degradation Of Phenanthrene And Benzo(A)Pyrene In A Field-Contaminated Sediment Inhabited By Ilyodrilus Templetoni: A Microcosm Study, Marilou Montevirgen Nabatilan

LSU Master's Theses

The influence of the oligochaete Ilyodrilus templetoni on the degradation of phenanthrene and benzo(a)pyrene present in a field-contaminated sediment was studied in microcosm experiments. Results indicate an enhanced degradation of phenanthrene and benzo(a)pyrene in microcosms inhabited by I. templetoni. Total phenanthrene reduction was observed at an average of 9.78 % in worm microcosms, while no reduction was observed in the control microcosms. Benzo(a)pyrene reduction, on the other hand, was determined at 78.60 % and 30.04 % in worm and control microcosms, respectively. The lowest concentrations of these PAHs at the end of 97-day study were observed well below the surface …

It is a 3 by 2 by 3 by 8 study where each statistical or data mining method has been employed to build a model for each of 8 different sample sizes and two different sampling methods. The effect of sample size on the overall performance of each model against two sets of test data are observed and compared. It is …

Ice Sheet Grounding Zone Deposits On Ross Sea Continental Shelf (Antarctica): Seismic Facies Analysis And P-Wave Reflectivity Attributes, Adeniyi Adewumi Saanumi

LSU Master's Theses

Subglacial till and overlying glaciomarine deposits are difficult to distinguish because the physical properties of subglacial till may vary depending on the drainage conditions of the rock directly beneath the ice sheet. Based on approximately 120 kilometers of multi-channel seismic data, detailed seismic facies analysis and amplitude variation with offset (AVO) analysis are carried out to examine the distribution of ice sheet grounding zone deposits on the continental shelf of the Northern Basin, Ross Sea (Antarctica) and infer the physical properties of interpreted subglacial till. Seismic facies analysis led to the differentiation of distinct sub-environments around a grounded ice sheet: …

Asymmetry Of Tidal Plume Fronts In An Eastern Boundary Current Regime, David A. Jay, Jiayi Pan, Philip M. Orton, Alexander R. Horner-Devine

Civil and Environmental Engineering Faculty Publications and Presentations

The Columbia River tidal plume or near-field is formed twice daily by the ebb outflow of the Columbia River. It is a part of a larger, anticyclonic plume bulge, which in turn is embedded in far-field plume and coastal waters. Because of the mixing caused directly and indirectly by plume fronts, the interaction of the tidal plume and bulge with the California Current upwelling regime plays a vital role in coastal productivity on the Oregon and Washington shelves. The tidal plume is initially supercritical with respect to the internal Froude number on all stronger ebbs. It is separated from the …

Export-Led Growth In Southern Africa, Ramona Sinoha-Lopete

LSU Master's Theses

The objective of this thesis was to examine the validity of the Export-Led Growth (ELG) hypothesis in nine Southern African countries using annual data for the period 1980-2002. The thesis used time series econometric techniques to test for the causal linkage between exports and economic growth in Southern Africa. Dynamic econometric models were estimated to test for time series properties: unit root (ADF and PP tests), cointegration (Johansen’s procedure), and Granger-causality (Likelihood Ratio test-LR). The results of the unit root tests show that most of the series are stationary in first differences (series in levels have unit root—I(1)). Co-integration and …

The Macarthur-Bates Communicative Development Inventory As An Assessment Tool For Low-Income, African American Children, Elizabeth Waters Wooden

LSU Master's Theses

The purpose of this study was to examine the usefulness of the MacArthur- Bates Communicative Development Inventory (CDI) as an assessment tool for low-income, African American (AA) children. The data were from eighty-seven typically developing AA children, aged 8 to 30 months; these children were recruited from childcare centers that served low-income populations in Baton Rouge, Louisiana. Each participant’s primary caregiver completed a biographical sketch and a CDI inventory. Two analyses were completed. The first analysis examined the distribution of the CDI scores relative to the child’s age, gender, birth order, and level of maternal education. The second analysis involved …

Positional Effects Of Trna Genes: Transfer Rna Genes As Chromatin Boundaries In Saccharomyces Cerevisiae, Tiffany Anne Simms

LSU Master's Theses

Recently, much evidence has been brought forth into the scientific community supporting the idea that RNA Polymerase III transcribed regions of DNA may serve as chromosomal landmarks for silencing. Transfer RNA genes are known to involve themselves in several extra-transcriptional functions within the chromosome, including the pausing of replication forks, Ty element integration, tRNA position effects (repression of neighboring genes), acting as a barrier to the spread of heterochromatin, and over-riding nuclosome positioning sequences. Our results suggest that many tRNA genes may serve these functions as well as exhibiting behavior similar to metazoan insulators. Also, ETC (Extra TFIIIC) sites within …
