Modulation Of Cholinergic Signaling In Embryonic Zebrafish: Anatomical And Behavioral Consequences, Evdokia Menelaou

LSU Doctoral Dissertations

Smoking during pregnancy remains a major health concern in the United States. Nicotine is one of the main ingredients of cigarettes and a neurotoxicant which has been purported to affect many aspects of nervous system development causing long-term abnormalities in the offspring. We took advantage of the zebrafish model to investigate the effects of nicotine in nervous system anatomy and function. It was previously reported that embryonic nicotine exposure causes pathfinding errors in secondary motoneuron (SMN) axons through the activation of nicotine acetylcholine receptors (nAChRs). However, the nicotine-induced effects on SMN pathfinding coincided with muscle degeneration. We hypothesized that nicotine …

In Sickness And In Health: Experiencing Medical Spaces In Mbarara (Uganda), Kara E. Miller

LSU Master's Theses

This thesis is a contribution to cross-cultural studies on health and medicine explored through the material and symbolic facets of health care in a region of Southwest Uganda. Research conducted in the healing spaces of Mbarara reflects traditions in the anthropology of the body and brings a lived perspective to conditions of sickness and wellness. By tracing the biographies of treatment spaces, the medical landscape is evaluated in terms of participants’ perceptions, convictions, and knowledge sets. Phenomenological methodology is employed in this exploration of ill states and curative places, which braids concepts and academic work in the areas of medicine, …

The Population Of Sap And Tsap Isomers In Cyclen-Based Lanthanide(Iii) Chelates Is Substantially Affected By Solvent, Kyle J. Miller, Ali A. Saherwala, Benjamin C. Webber, Yunkou Wu, A. Dean Sherry, Mark Woods

Chemistry Faculty Publications and Presentations

The square antiprism/twisted square antiprism ratio in LnDOTA-tetraamide chelates is a critical parameter in governing water-exchange kinetics and ultimately the utility of a chelate as a PARACEST MRI contrast agent. In LnDOTA-tetraamide chelates with tertiary amides, this ratio and the rate of interconversion between these two structural isomers are found to be dramatically dependent upon the solvent and possibly other local environmental factors.

Polymeric Paracest Mri Contrast Agents As Potential Reporters For Gene Therapy, Yunkou Wu, Christiane E. Carney, Michael Denton, Elaine Hart, Piyu Zhao, Daniel N. Streblow, A. Dean Sherry, Mark Woods

Chemistry Faculty Publications and Presentations

Gene therapy is a potentially powerful treatment approach that targets molecular remedies for disease. Among other challenges it remains difficult to monitor gene delivery and its downstream metabolic consequences. Approaches to MRI gene reporters have been reported but few have the potential for translation beyond isolated cell systems. Herein, we report a polycationic polymer MRI contrast agent that binds to DNA in a ratio of one monomer unit per phosphate group of DNA. Significantly, this binding event diminishes the MR contrast signal from the agent itself potentially providing a platform for imaging delivery and release of a gene into cells …

Cest And Paracest Mr Contrast Agents, Ileana Hancu, W. Thomas Dixon, Mark Woods, Elena Vinogradov, A. Dean Sherry, Robert E. Lenkinski

Chemistry Faculty Publications and Presentations

In this review we describe the status of development for a new class of magnetic resonance (MR) contrast agents, based on chemical exchange saturation transfer (CEST). The mathematics and physics relevant to the description of the CEST effect in MR are presented in an appendix published in the online version only. We discuss the issues arising when translating in vitro results obtained with CEST agents to using these MR agents in in vivo model studies and in humans. Examples are given on how these agents are imaged in vivo. We summarize the status of development of these CEST agents, and …

An Annotated Catalogue Of Selected Cuban Piano Works From The 18th-20th Centuries, Nikie Oechsle

LSU Doctoral Dissertations

The piano music of Cuba encompasses a large body of valuable music that is yet to be explored fully on the international scene by performers and teachers. The purpose of this volume is to provide a guide that will enable performers and teachers to quickly reference, and more fully investigate the available music of Cuban composers. This is accomplished by providing description and levels of selected Cuban piano works from the eighteenth through twentieth centuries in catalogue format, as well as by providing descriptions of dances and dance forms found in the included literature.

Dopaminergic Input To The Equine Pituitary: Seasonal And Estradiol Effects, Sarah Case Clavier

LSU Master's Theses

Two experiments were conducted to study the effects of season and estradiol administration on dopaminergic input to the equine adenohypophysis. Experiment 1 began in the spring with 8 mares and 8 stallions and was repeated again in the summer, fall, and winter. Horses were given sulpiride injections of eight incremental doses (0.25 to 32 µg/kg BW). Within each group of 8 horses, half received the sulpiride in an increasing manner, the other half in a decreasing manner. Prolactin concentrations peaked in the first 15 to 30 min in all horses in all seasons. Prolactin areas under the curve increased (P < 0.001) with increasing doses of sulpiride, and were highest (P < 0.05) in March for stallions, but in June for mares. The calculated half-maximum values, which should be proportional to the dopaminergic input to the pituitary, were lowest (P < 0.05) in June and greatest in September. The variation in half-maximum values with season indicated a change in dopaminergic input to the pituitary, with lowest input occurring in June in both sexes. Experiment 2 was designed to determine if the degree of dopaminergic input to the adenohypophysis is altered by estradiol administration. Twelve geldings were used. On day 0, geldings received an i.m. injection of either estradiol cypionate (ECP; n = 6) or vegetable oil (n = 6) at one of two dose volumes (2 vs. 10 mL). On day 6, all geldings received an injection of sulpiride at 0.082 µg/kg BW in saline. Sulpiride injections were repeated every other day with the dose increasing each day, from 0.164 to 100 µg/kg BW. Estradiol pretreatment increased (P < 0.05) the prolactin response to sulpiride at the 2.56 µg/kg dose and higher. However, the half-maximum values for ECP-treated and control geldings did not differ, indicating that the amount of sulpiride needed to counterbalance the amount of dopamine reaching the pituitary was unaltered by estradiol treatment. It was concluded that estradiol likely stimulates prolactin production and secretion after sulpiride directly at the lactotrope level, rather than by decreasing hypothalamic dopamine input to the lactotropes.

"To Liberate Communication": The Realist And Paul Krassner's 1960s, Terry Joel Wagner

LSU Master's Theses

Paul Krassner began publishing a small-circulation magazine called The Realist in New York City in 1958 because he believed there existed excessive restraints on speech in American culture. The publication began with a combination of earnest critiques and good-humored satires on such topics as organized religion, sexual mores, Cold War paranoia, and civil rights. By the mid-sixties, the magazine was enlarging the space not just for what opinions could be expressed but also for the way those opinions were expressed and, in the process, testing the boundaries of obscenity. As Krassner became a bitter opponent of the Vietnam War and …

Knowledge Gap And Cable Music Television: A Survey Of Mtv, Bet, And H1 Target Audience Members, Katharine Claire Gavin

LSU Master's Theses

American youth and adolescents have the highest rate of teenage pregnancy and sexually transmitted infections in the industrialized world. Entertainment media, the preferred genre of today’s adolescents, depicts sex, drugs, and alcohol use at a greater rate than any other genre of programming. What are health communication strategists doing to counter the widespread, inaccurate portrayals often depicted in this type of programming? With previous knowledge gap and health communication research failing to examine youth oriented and racial targeted entertainment programming, this study utilizes a survey to analyze BET, MTV, and VH1 audiences’ health knowledge, recall, and attitude toward PSAs to …

Cooling-Off And Secondary Markets: Consumer Choice In The Digital Domain, Michael Mattioli

Articles by Maurer Faculty

This article studies the law and economics of cooling-off periods and secondary markets for online media. The discussion is fueled by a current debate: In July 2009, the online retail juggernaut, Amazon.com, remotely deleted literary classics from consumers’ portable “Kindle” reading devices. The public outcry and class-action lawsuit that followed have reinvigorated an ongoing debate about how much control digital media distributors should wield. Pundits and plaintiffs argue that too often, digital distributors like Amazon impair consumer freedom by misusing Digital Rights Management (DRM) software systems. However, these same systems could also provide significant benefits that have largely gone ignored. …

Characterization Of Rock/Fluids Interactions At Reservoir Conditions, Dayanand Saini

LSU Doctoral Dissertations

In this study, interfacial phenomena of spreading, wettability, and rock/oil adhesion interactions in complex rock/oil/water systems were characterized at reservoir conditions of elevated pressures and temperatures. Capabilities of both ambient and reservoir condition optical cells were used for measuring the oil/water interfacial tension and dynamic (the water-receding and the water-advancing) contact angles for various complex rock/oil/water systems. Well known sessile oil drop volume alteration method was successfully used in this study for evaluating the applicability of the modified Young’s equation for characterizing the line tension in complex rock/oil/water systems at reservoir conditions. This appears to be first time when rock/fluids …

German Enemy Aliens And The Decine Of British Liberalism In World War I, Ansley L. Macenczak

LSU Master's Theses

After the start of World War I in 1914, the British government began internment of enemy alien men, disrupting the large German population settled in the country. This move seemed to be in complete contrast in comparison to the lax immigration laws during the long nineteenth century, when Great Britain had one of the most liberal immigration laws of any country in Europe. The British public was proud of this tradition and Britain’s image as an open haven for refugees and individuals seeking a better life. Foreigners were attracted to Britain by its liberal traditions, most clearly exemplified by the …

The Legal Challenge Of Protecting Animal Migrations As Phenomena Of Abundance, Robert L. Fischman, Jeffrey B. Hyman

Articles by Maurer Faculty

Animal migrations are as familiar as geese in the sky on a fall afternoon and as mysterious as the peregrinations of sea turtles across thousands of miles of open ocean. This article discusses the distinguishing attributes of animal migrations, why they are important to biodiversity conservation, and the legal challenges posed by migration conservation. In particular, the article focuses on those aspects of migration conservation that existing law, dominated by imperiled species protection, fails to address. It consequently suggests law reforms that would better conserve animal migrations. A step toward serious legal efforts to protect the process and function of …

Where Cultures And Sovereigns Collide: Balancing Federalism, Tribal Self-Determination, And Individual Rights In The Adoption Of Indian Children By Gays And Lesbians, Steve Sanders

Articles by Maurer Faculty

This article analyzes the complex interplay between adoption (traditionally a matter reserved to state family law) and the federal Indian Child Welfare Act in the context of adoptions by gays and lesbians.

As a federal statute that partially preempts state law for the benefit of Native Americans, ICWA implicates three sovereigns: the United States, the state where the adoption petition is brought, and the tribe whose child is the focus of the proceeding. This interplay of sovereigns in itself makes Indian child welfare law complicated and interesting. Beyond these sovereign interests, also to be considered are the interests and rights …

Impeach Brent Benjamin Now!? Giving Adequate Attention To Failings Of Judicial Impartiality, Jeffrey W. Stempel

Scholarly Works

In Caperton v. A.T. Massey Coal Co., Inc., 129 S. Ct. 2252 (2009), the Supreme Court by a 5-4 vote vacated and remanded a decision of the West Virginia Supreme Court of Appeals in which Justice Brent Benjamin cast the deciding vote in favor of Massey, a company run by Don Blankenship, who had provided $3 million in support to Benjamin during his 2004 election campaign.

Despite the unsavory taste of the entire episode, the Court was excessively careful not to criticize Justice Benjamin. Overlooked because of this undue judicial civility and controversy about the constitutional aspects of the decision …

Completing Caperton And Clarifying Common Sense Through Using The Right Standard For Constitutional Judicial Recusal, Jeffrey W. Stempel

Scholarly Works

In Caperton v. A.T. Massey Coal Co., the U.S. Supreme Court vacated a state supreme court decision in which a justice who had received $3 million in campaign support from a litigant cast the deciding vote to relieve the litigant of a $50 million liability. The Court reached this result, one I view as compelled by common sense, through a 5-4 vote, with the dissenters, led by Chief Justice John Roberts and Justice Antonin Scalia, minimizing the danger of biased judging presented by the situation and questioning the practical feasibility of the Court's approach as well as the wisdom of …

Surfactant-Induced Flow Behavior Effects In Gas Condensate Reservoirs, Bikash Deep. Saikia

LSU Master's Theses

Natural gas, which accounts for a quarter of world’s energy, has been a major energy source because of its abundance and less impact on environment. With explorations at higher depth, pressure and temperature, the share of gas condensate reservoirs to global gas production is increasing. A unique production challenge associated with these reservoirs is the condensate blockage problem, which is the buildup of condensate liquid saturation around wellbore as a result of drawdown below dew point pressure. Mitigation of this problem requires in depth understanding of the multiphase flow of liquid and gas. Surfactants are well known in the literature …

What Content Makes People Want To Use Sports Websites?, Cara Francesca De Carlo

LSU Master's Theses

This study looked at sports websites to see how the variables information, humor, entertainment, community, and credibility affected sports website users’ intentions to use and re-use sports websites. Three groups of 25 and one group of 30 participants each completed a website viewing activity and corresponding survey. There were four website viewing activities (one for each group). The activities led participants on tours of ESPN.com, Deadspin.com, Football Outsiders, and Yahoo! Sports. Furthermore, the tours were designed to expose participants to the variables (as defined under disposition theory and uses and gratifications). Likewise, the corresponding survey assessed participants’ intentions to use …

A Performance Guide To Lori Laitman's Living In The Body, Kathryn Mary Drake

LSU Doctoral Dissertations

The purpose of this document is to provide a complete performer’s guide to American composer Lori Laitman’s Living in the Body, a song cycle consisting of six songs for soprano and saxophone set to the poetry of Joyce Sutphen. Living in the Body is one of very few cycles written for soprano and saxophone, and the combination is both unusual and interesting to investigate. The cycle explores letting go of the past and focusing on what will happen in the second half of life. The text is set expertly for soprano, bringing important words to the listener’s attention while keeping …

Friction And Wear At Elevated Velocities, Adam Lodygowski

LSU Doctoral Dissertations

Severe contact stress problems generate high temperature and create thermomechanical gouging and wear due to high velocity sliding between contacting materials. The major consideration is to develop an experimental and theoretical model for the material constitutive behavior in order to better characterize and predict the internal failure surroundings the gouging and wear events and understand the physical behavior of high speed contact environment. An enhancement of an existing tribometer device developed by Philippon et al. [2004] is made up of a dynamometer ring and a load sensor that allows to apply an apparent normal force on specimens and measure frictional …

Hamilton-Jacobi Theory For Optimal Control Problems On Stratified Domains, Richard Charles Barnard

LSU Doctoral Dissertations

This thesis studies optimal control problems on stratified domains. We first establish a known proximal Hamilton-Jacobi characterization of the value function for problems with Lipschitz dynamics. This background gives the motivation for our results for systems over stratified domains, which is a system with non-Lipschitz dynamics that were introduced by Bressan and Hong. We provide an example that shows their attempt to derive a Hamilton-Jacobi characterization of the value function is incorrect, and discuss the nature of their error. A new construction of a multifunction is introduced that possesses properties similar to those of a Lipschitz multifunction, and is used …

Post-Diaster Family Resilience: The Use Of Humor As A Coping Strategy, Bridgette Boe O'Connor

LSU Master's Theses

The purpose of this study was to investigate the use of humor as a coping strategy among Hurricane Katrina survivors. The data for this study were collected in the first wave of a larger project on families and disasters. Using Geographic Information Systems (GIS) by combining Census data with storm damage estimates and purposive sampling, 50 participants affected by Hurricane Katrina from a single suburban community in Southern Louisiana in early spring 2006 were recruited and interviewed. When the interviews were qualitatively analyzed with a focus on humor, it became clear that families used humor even at such a devastating …

The Feminization Of Private Investigation: A Sociological Analysis, Jessica Simpson Pearce

LSU Doctoral Dissertations

This dissertation outlines the occupation of private investigation and the role that females play within that profession. The difficulties women experience in male-oriented occupations remains noteworthy in sociological research today. Progress has been made, yet many barriers still exist for women. These include structural, social, and cultural factors that influence women and/or the jobs that they hold. With the completion of interviews with twenty-six female private investigators, I was able to analyze the existing structural, interactional, and gender barriers which moderate the number of women that work as private investigators. Few studies have examined this occupation and this gap may …

Stereotype And Representation Of Near And Middle Eastern Peoples In La Bande Dessinee, Brandon Matthew Thomas

LSU Master's Theses

Representation of social groups in the comics is serious. In 2006, a series of twelve cartoons published in a Danish newspaper sparked a controversy that precipitated the deaths of hundreds of people. The images depicted Mohammed and other images that supposedly mocked Islam. All across Europe, the Middle East, and North Africa protesters paraded through the streets, some calling for the death of the cartoonists. Trials in Europe over the publication of these cartoons resulted in several firings. Counter protests have also arisen. These protesters found grievance with the firings, claiming that the freedom of the press was being violated …

Low Co-Cultivation Temperature At 20oc Improved Agrobacterium Tumefaciens-Mediated Transformation Of Tobacco Leaf Disks, Guiying Su

LSU Master's Theses

I investigated the effect of co-cultivation temperature and binary Ti vectors on the fresh weight yield of leaf disks of tobacco (Nicotiana tabacum L. cv. Xanthi (nn, Smith) after Agrobacterium tumefaciens-mediated transformation. I concluded that the temperature at 20ºC during co-cultivation of leaf disks with A. tumefaciens was the most critical factor on the reproducible enhancement of fresh weight yield. The highest fresh weight increase and presumably transformation efficiency was achieved under the following experimental conditions: A. tumefaciens strain LBA4404 containing pLSU binary Ti vector was grown overnight at 28oC in liquid Agrobacterium medium and the concentration was adjusted to …

Influences On Public Support For Green Infrastructure: An Examination Of Urban Wetland Restoration In Post-Katrina New Orleans, Lynette C. Overholser

LSU Master's Theses

The research examines patterns of likely support for urban wetland restoration in the Greater New Orleans area. Through multi-variate statistical analysis of responses derived from an original survey of homeowners in New Orleans, key factors are identified that explain variation in residents’ willingness to accept such areas and their perceptions of ecological benefits associated with a theoretical wetlands restoration design for the Gentilly area. Further, the analysis determines the extent to which direct experience with Hurricane Katrina may influence public support for this and other green infrastructure projects. The results of the data collected show that many people in New …

Creating Brands Online: Third Party Opinions And Their Effect On Consumers' Trust In Brands And Purchase Intentions, Pavel Mrazek

LSU Master's Theses

Consumer lack of trust in online vendors and brands is identified as one of the biggest obstacles in the growth of e-commerce. This study examined how third-party product reviews help in building consumers’ trust, in consumers’ perception of product quality, their brand attitudes and consumers’ purchase intention. The six cell experimental design tested the effect of consumer and expert online product reviews on fictitious web sites for high-involvement and low-involvement products. The findings indicate that online consumer product reviews perform better than online expert product reviews and no product reviews. Online product reviews affected visitors to a web site with …

Paths Of Most Resistance: Navigating The Culture Industry In William Faulkner, Richard Wright, Delmore Schwartz, And Eudora Welty, Jason Dupuy

LSU Doctoral Dissertations

This dissertation explores how four modernist writers of the 1930s and 1940s—William Faulkner, Richard Wright, Delmore Schwartz, and Eudora Welty—used their works to present ways to resist and navigate what they present as the frequently reductive worldview offered by the culture industry. Faulkner tends to show the culture industry as selling easy answers that focus on the end result, which allows his characters to approach the culture industry with a sense of fatalism. To resist this, Faulkner stresses a step-by-step, complex dialectical understanding of the culture industry, one that shows the fissures in its seemingly straightforward narratives and allows the …

Social Shopping For Fashion, Jiyun Kang

LSU Doctoral Dissertations

In spite of the significance of social shopping in the context of fashion consumption, its definitions, boundaries, and explanations have not yet been systematically established in literature. The purpose of Study 1 was to develop a reliable and valid scale of social shopping for fashion. With the scale, Study 2 aimed to develop and test a structural model of social shopping process. In Study 1, a three-step procedure for scale development was followed: item generation, scale purification, and scale validation. As a result, a five-dimensional scale, along with sixteen behavioral items, was developed representing distinctive dimension of social shopping for …
