Preferences And Values For The Gulf Coast Ocean Observing System, Cody Lynn Plummer Jan 2017

Preferences And Values For The Gulf Coast Ocean Observing System, Cody Lynn Plummer

LSU Master's Theses

Integrated Ocean Observing Systems (IOOS) provide real time oceanic data and sea state forecasting information that is utilized by numerous public and private sectors engaging in maritime activities. The U.S. Gulf Coast constituent of this system (GCOOS) consists of 321 platforms, buoys, and sensors that provide measurements of wind speed, wave height, water quality, and other parameters. Government entities have proposed an expansion of this infrastructure by 40% at an estimated cost of $35 million for installation and $33 million annually for maintenance. As part of a larger project commissioned to estimate monetized benefits of this expansion, this study applied …

Cathartic Ethics In Psychoanalysis, Dylan Timothy O'Brien Jan 2017

Cathartic Ethics In Psychoanalysis, Dylan Timothy O'Brien

LSU Master's Theses

This thesis examines the complex role of ethics within Psychoanalytic theory, finding not a prescriptive ethics, but a reference to ethics in the cathartic methodology that I argue underpinned Psychoanalytic thought from the very beginning. The introduction provides the reader with the necessary background to the material to be covered. The first chapter examines the neglectful attitude found throughout the foundational writings of Psychoanalytic theory in the work of Sigmund Freud, as well as covering two different methods by which ethics are often reduced, and which Freud successfully avoided. The second chapter seeks the origin of an alternative ethics in …

Measuring The Effects Of Recycled Water On The Growth Of Three Algal Species: Tisochrysis Lutea, Chaetcoeros Calcitrans, And C. Muelleri In A Commercial-Scale Oyster Hatchery, Lisa Marie Bourassa Jan 2017

Measuring The Effects Of Recycled Water On The Growth Of Three Algal Species: Tisochrysis Lutea, Chaetcoeros Calcitrans, And C. Muelleri In A Commercial-Scale Oyster Hatchery, Lisa Marie Bourassa

LSU Master's Theses

Algal production is often the limiting factor in large-scale oyster hatcheries, and constant, reliable production is required to grow enough algae to support all oyster larvae and broodstock grown and conditioned in a hatchery. The algal rooms in the Michael C. Voisin Oyster Hatchery at Grand Isle, LA are temperature-controlled to maintain consistent temperature, but this hatchery is also unique in its ability to recycle natural seawater pumped from the northern Gulf of Mexico. Effects of recycling seawater on algal production in an oyster hatchery, however, are undocumented. In this study, Tisochrysis lutea, Chaetoceros calcitrans and C. muelleri were grown …

Development And Test Of A Sweet Sorghum Feedstock Separation Technology And The Effect Of Trash On Fermentable Sugar Yield In Juice And Syrup, Edgar Jose Tobias Corado Jan 2017

Development And Test Of A Sweet Sorghum Feedstock Separation Technology And The Effect Of Trash On Fermentable Sugar Yield In Juice And Syrup, Edgar Jose Tobias Corado

LSU Master's Theses

In the recent years, processing sweet sorghum feedstock to obtain syrup for biofuels production is an option that has gained attention, especially where sugar cane milling infrastructure is already available; however, the leafy matter and panicles (trash) in the feedstock could negatively impact the process. Therefore, it seems sensible to reduce the trash level in the feedstock prior to milling and expand the current knowledge on the effect of trash in the juice and syrup. In this project, a pneumatic system to separate the leaves from sweet sorghum harvested with a sugar cane billet harvester was tested and a panicles …

Developmental Functioning Of Infants And Toddlers With Autism And Cerebral Palsy, Xinrui Jiang Jan 2017

Developmental Functioning Of Infants And Toddlers With Autism And Cerebral Palsy, Xinrui Jiang

LSU Master's Theses

Children with Autism Spectrum Disorder (ASD) often have one or more comorbid medical conditions including cerebral palsy (CP). Due to the overlaps between ASD and CP symptomatology (e.g., impairments in speech, repetitive movements, atypical sensory issues), co-occurring CP often leads to delayed diagnoses of ASD interfering with early interventions and subsequently affecting functional outcome. Utilizing the Baby and Infant Screen for Children with aUtIsm Traits-Part 1 (BISCUIT-Part 1) and the Battelle Developmental Inventory, Second Edition (BDI-2), this study assessed and compared ASD symptomatology and developmental functioning in three groups of infants and toddlers, namely, those with ASD only, those with …

Pharmacokinetics Of Micronized Progesterone Administration In Female Dogs, Raphael Anthony Malbrue Jan 2017

Pharmacokinetics Of Micronized Progesterone Administration In Female Dogs, Raphael Anthony Malbrue

LSU Master's Theses

Hypoluteoidism in the bitch is described as a reproductive condition in which insufficient levels of endogenous progesterone are present resulting in failure to maintain a functional secretory endometrium. This condition can prevent normal embryo implantation, development, and ultimately end in pregnancy loss. Hypoluteoidism in the bitch is a rising concern in small animal theriogenology and current medical therapies available to veterinarians are limited. The aim of this study was to determine the pharmacokinetics (PK) of intravaginally (Crinone®, Serono Laboratories, Norwell, MA) and orally delivered micronized progesterone (Prometrium®, Solvay Pharmaceuticals, Inc., Marietta, GA) in the bitch. We hypothesized that both vaginal …

Biology And Ecology Of Crapemyrtle Bark Scale, Acanthococcus Lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), Zinan Wang

LSU Master's Theses

The crapemyrtle bark scale, Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an exotic pest on crapemyrtles, Lagerstroemia spp. (Myrtales: Lythraceae). Because of its recent arrival in the US, little is known about its biology and ecology. The purpose of my thesis was to improve the knowledge about A. lagerstroemiae in four aspects involving its thermal tolerance, physiological adaptations to cold temperatures, temperature-dependent development and host range. Thermal tolerance was determined to understand how temperature extremes constrain the distribution of A. lagerstroemiae in the US. Results suggested that A. lagerstroemiae can tolerant high heat, but its potential distribution to the northern US …

Soil Properties' Response To Wheat And Corn Stubble Residue Management In Louisiana, Autumn Danielle Acree Jan 2017

Soil Properties' Response To Wheat And Corn Stubble Residue Management In Louisiana, Autumn Danielle Acree

LSU Master's Theses

Crop residue plays an important role in improving soil fertility. Crop residue affects soil biological and chemical properties by increasing soil organic matter, nutrient status and availability, and microbial activity. The degree of the effects of crop residue on soil fertility depends on the crop residue management practice. Samples were collected in 2014 in wheat (Triticum spp.) stubble and corn (Zea mays) stubble residue. A second soil sample collection under wheat stubble residue was taken in 2015 in the prescribed fire and no-till sections. A total of 342 soil samples (0-2.5cm) were collected across conventional tillage, no-till, and prescribed fire …

Gender Beyond Birth: Gender Non-Conforming Students Lived Experiences Residing On-Campus In The Southeast, Tiffany Marlene Shierling Jan 2017

Gender Beyond Birth: Gender Non-Conforming Students Lived Experiences Residing On-Campus In The Southeast, Tiffany Marlene Shierling

LSU Master's Theses

In this study, using a qualitative approach, gender non-conforming students lived experience living on campus in the south is being investigated. “Trans* students remain largely invisible through college records as no data is collected consistently on their enrollment” (Nicolazzo, 2016 p. 539). Although this is true of all gender non-conforming students, it is even more relevant to those that attend universities in the Southeast. Gender non-conforming students are attending universities in higher numbers than every reported before and yet, student affairs still does not have a theory that relates to these students when teaching their graduate students. The psychological literature …

An Investigation Of The Relationship Between Seizures And Autism Symptomology In Young Children, Claire O. Burns Jan 2017

An Investigation Of The Relationship Between Seizures And Autism Symptomology In Young Children, Claire O. Burns

LSU Master's Theses

Autism spectrum disorder (ASD) is a condition that consists of deficits in social communication as well as restricted, repetitive interests or behaviors. Individuals with ASD also often have comorbid psychiatric and medical disorders. One such concern is high rates of seizures and epilepsy. Researchers have found that rates of seizures tend to be higher in individuals with ASD who also have more impaired functioning. However, few studies have examined how the presence of seizures is related to symptoms of ASD. The current study aimed to expand the extant literature by investigating whether a history of seizures is associated with ASD …

Susceptibility Of The Southern House Mosquito, Culex Quinquefasciatus, In East Baton Rouge Parish To Larval Insecticides, Nicholas Alexander Delisi Jan 2017

Susceptibility Of The Southern House Mosquito, Culex Quinquefasciatus, In East Baton Rouge Parish To Larval Insecticides, Nicholas Alexander Delisi

LSU Master's Theses

Mosquito control districts in Louisiana focus their efforts on Culex quinquefasciatus, the primary vector of West Nile virus in the southern United States, with rigorous larvicide treatments. However, the development of resistant populations of Cx. quinquefasciatus in response to extensive insecticide application has been demonstrated repeatedly. Examining changes in insecticide susceptibility and larvicide efficacy in real world scenarios can help inform mosquito control districts as to whether or not their treatments are killing mosquitoes. We hypothesized that frequent larvicide applications for the control of mosquitoes in East Baton Rouge Parish had lowered susceptibility of wild Cx. quinquefasciatus to insecticides, and …

Non-Metric Cranial Differentiation Between Asian And Native American Populations For Ancestry Assessment, Dominique Marie Bodoh Jan 2017

Non-Metric Cranial Differentiation Between Asian And Native American Populations For Ancestry Assessment, Dominique Marie Bodoh

LSU Master's Theses

Assessing ancestry from skeletal remains provides important information to aid in personal identification. However, trying to specify ancestry for Native American and Asian populations in the United States is a current challenge in laboratory analyses. Both Native American and Asian populations are still often combined in research for a variety of reasons: small sample sizes, skeletal similarities and less emphasis in contemporary literature. Historically, Carlton Coon, in 1939, and Riesenfield, in 1956, refer to this combination of both Native American and Asian populations as “Mongoloid,” a term which is deemed by many as an offensive and inaccurate categorization of both …

Occurrence And Phenology Of Polistine Wasps (Hymenoptera: Vespidae) In Southern Louisiana, Scott Nacko Jan 2017

Occurrence And Phenology Of Polistine Wasps (Hymenoptera: Vespidae) In Southern Louisiana, Scott Nacko

LSU Master's Theses

Phylogenetic studies suggest that historically all paper wasps (Vespidae: Polistinae) in North America have tropical origins. However, paper wasps have adapted to thrive in temperate conditions. Subtropical and temperate climates allow for a study of adaptive traits which can be retained or lost within populations, and ultimately help elucidate the process of social wasp evolution. Additionally, species occurrence patterns can help us to understand partitioning and resource use within populations. We investigated the occurrence and phenology of each Polistine species found at four sites in southern Louisiana around Baton Rouge, and also examined the occurrence and behavior of a closely …

Oblivion, Michael Stumbras Jan 2017

Oblivion, Michael Stumbras

LSU Master's Theses

I am fascinated by the myriad ways humans construct meaning in the face of existential uncertainty. For the exhibition Oblivion, I endeavor to provide a gallery experience, a body of metaphorically charged functional vessels, and a number of ritualistic accoutrements that address death, futility, and the passage of time as it inexorably flows toward obsolescence. The process of handcraft and the method of firing that I employ highlights the absurdity of the endeavor of the handmade: the seemingly futile and interminable quest for perfection and meaning. This futilitarian pottery exaggerates the errors of the hand and flaunts artifacts of the …

Chronicle & Character, Taryn Moller Nicoll Jan 2017

Chronicle & Character, Taryn Moller Nicoll

LSU Master's Theses

In this thesis paper, I argue that the works in the exhibition 'Chronicle & Character' aim to demonstrate artistic citizenship and can contribute positively to society by provoking conversation about universally applicable (but often uncomfortable) topics. Experts such as David J. Elliot state that being an artistic citizen means that one’s concerns as an artist must shift from issues constrained to the artist alone to those of the artist’s surrounding community. The exhibition 'Chronicle & Character' contains works that serve as detailed chronicles of the medical or physiological experiences of my loved ones. This body of work presents how three …

A Vast Injustice: The Public Debate And Legislative Battle Over Compulsory Eugenic Sterilization In Louisiana, 1924 -- 1932, Adelaide Hair Barr Jan 2017

A Vast Injustice: The Public Debate And Legislative Battle Over Compulsory Eugenic Sterilization In Louisiana, 1924 -- 1932, Adelaide Hair Barr

LSU Doctoral Dissertations

From 1924 to 1932, Louisiana lawmakers considered five bills that would have granted superintendents of state institutions and some private hospitals the authority to forcibly sterilize their patients. Based on similar legislation passed in thirty-six other states, the bills cited eugenics as evidence that stripping these patients of their ability to reproduce would prevent the conditions such as feeblemindedness from passing on to the next generation. Although none of the bills passed both houses of the Louisiana legislature, a couple of them came dangerously close to becoming law. The debate among legislators, professionals, and social reformers provides a greater understanding …

Patterns Of Diversification In A Neotropical Radiation Of Birds (Aves: Furnariidae), Glenn F. Seeholzer Jan 2017

Patterns Of Diversification In A Neotropical Radiation Of Birds (Aves: Furnariidae), Glenn F. Seeholzer

LSU Doctoral Dissertations

Ecology and the role of natural selection in lineage diversification has been a central topic in evolutionary biology since Darwin. At the macroevolutionary scale, this idea is embodied in the ecological theory of adaptive radiation, which posits that rapid diversification is driven by ecological adaptive radiation in which speciation is coupled with niche divergence. Within species, the theory of ecological speciation proposes that local adaptation drives speciation by reducing gene flow among populations occupying different environments either by directly reducing migration or by reducing the fitness of migrants. Much progress has been made testing these predictions in a multitude of …
