Foreign News And Public Opinion: Attribute Agenda-Setting Theory Revisited, Asya A. Besova

LSU Master's Theses

This study contributes to the body of research on public opinion and media coverage of foreign news by examining the coverage of nine foreign countries in The New York Times and The Times. Media coverage and the public opinion about foreign nations were strongly correlated. Specifically, negative coverage tends to have more agenda-setting effects than neutral and positive coverage. The findings also suggest that media portray foreign countries in a unidimensional fashion, by limiting the coverage around a few policy issues. Finally, the U.S. and the U.K. media coverage of foreign nations were very similar.

Entertainment Media And "Backstage" Event Framing: How 24 Defines Torture, Skye Chance Cooley

LSU Master's Theses

The purpose of the current study is to examine how the prime time television show 24 frames torture by US government officials almost exclusively in scenarios of high-consequence, high-confidence that are not supported by public opinion polls, provide contextual rationalizations that are unrealistic, show torture methods as a viable means to gain needed information, and show enemy combatants torturing U.S. citizens. Through a quantitative content analysis of torture on the television series 24 and an analysis of focus groups’ reactions to select episodes of 24 portraying torture in such scenarios, the study seeks to investigate the role of entertainment media …

Richard Rorty's Map Of Political Misreading, Shaun Kenan King

LSU Master's Theses

For more than a quarter century, Richard Rorty was one of the most controversial writers. Critics of Rorty have often clustered their remarks around distinct themes within Rorty’s body of literature. Is Rorty’s criticism of the correspondence theory of truth valid and what standard of validity could confirm that? Does Rorty’s treatment of pragmatists such as William James and John Dewey accurately reflect their writings? Is Rorty’s brand of liberalism defensible when it assumes no non-circular form of justification can be proffered? These are the questions most often addressed by Rorty’s critics. He responded to their objections for two decades. …

Grinding The Axe Body Spray: Linking Gamer Experience And Brand Recall In Guitar Hero Iii, Miranda Coy Lemon

LSU Master's Theses

The growth in popularity of social video games that appeal to a wide variety of audiences offers new opportunities for in-game advertisers to reach beyond the traditional gamer market. The current study aimed to test the effectiveness of in-game advertising placements in the popular video game, Guitar Hero III, based on the Limited Capacity Model of Mediated Motivated Message Processing (LC4MP). The Limited Capacity Model predicts that experienced gamers utilize fewer mental resources when playing video games because the repeated action of playing video games eventually becomes automatic. An experienced gamer would therefore have a greater capacity to remember in-game …

Titian, The Pesaro, And The Frari: Different Strokes For Different Folks, Carl Edward Blyskal

LSU Master's Theses

This thesis parses two early paintings by the Venetian High Renaissance artist Titian. The discussions analyze the circumstances and patronage, compositional elements, iconography, and meanings of each work that lead through a maze of often contradictory art historical scholarship. This journey concludes by my proffering greater insights for each extraordinary painting by this internationally renowned artist. The earliest extant work by Titian--St. Peter Enthroned, with Donor and Pop--is a wonderful, if somewhat awkward, completion of a commission begun by Giovanni Bellini. Dating controversies over the centuries are examined, and a secure time-frame of 1506 to the first half of 1507 …

Iron And Zinc Physiology In Sweetpotato, Mary Catherine Singleton

LSU Master's Theses

Sweetpotato [Ipomoea batatas (L.) Lam.] is an important provider of nutrition in developing countries. High productivity in the form of starch and beta carotene richness underlies its potential. A sweetpotato with adequate levels of iron and zinc would greatly aid efforts to reduce dietary deficiencies of iron and zinc. The objective of this work is to document the physiological accumulation of iron and zinc in sweetpotato during development and the mechanisms responsible for iron uptake. Six varieties (‘IPS 163, ‘Beauregard’,‘Koto-puki’, ‘Pung-mi’, ‘Duanyanghon’, and ‘Xushu 18’) were compared to understand iron and zinc accumulation during development. Results showed that micronutrient content …

Airlift Assisted Wastewater Treatment, Brian Sidney Johnson

LSU Master's Theses

Static low density media (SLDM) filtration has been received with great admiration in the aquaculture industry and consequently spawned into the domestic wastewater setting on the pilot scale. This method of granular filtration uses plastic beads to facilitate the roles of both clarification and biofiltration into one compact unit. The fundamental operating principles utilized in this form of treatment can be greatly enhanced when they are coupled with self contained recirculation from airlift pumps. Recirculation of this type in a SLDM unit has the ability to provide multiple passes of the substrate in the wastewater through the bead bed to …

Experimental Investigation Of Unsaturated Soil Stiffness, Ananth Bukkapatnam Tirumala

LSU Master's Theses

Soil stiffness is a strain dependent non-linear parameter. Stiffness is the measure of soil deformation under a particular working load. It can used for predicting ground deformation in engineering earthworks such as highway embankments and foundations. Non-linear analyses for ground behavior have been widely used for developing models to predict the small –strain characteristics of the soil (Atkinson, 2000). This thesis provides a new insight into the behavior of soil stiffness. We used the wave propagation technique to determine the stiffness and term it as the small strain shear modulus (Gmax) of the soil. The objective of the thesis was …

Creatures Del Monte, Alejandro Arauz

LSU Master's Theses

To visually represent the multifaceted hybrid identity; a multidimensional artistic approach was necessary. I considered all the physical, psychological and cultural truths of my family. I explored our relationships, our behaviors and our responses as we simultaneously identify with the Latino and Anglo North American cultures and exist within its ever-changing parameters. Two streams of thought emerged in my artwork. One explores the characteristics and bi-cultural composition of my immediate family. The other looks at recalling past and distant members of my extended family as our points of origin while identifying the visible and invisible forces that shape our characters. …

Transcriptional Control Of The Adiponectin Gene By Stat5a, Joel Maier

LSU Master's Theses

Adiponectin is a hormone secreted from adipocytes that plays an important role in insulin sensitivity and fatty acid oxidation. The secretion of adiponectin from adipose tissue has been shown to be attenuated by treatment with prolactin (PRL). PRL is a potent STAT5 activator, and studies have indicated that it can modulate the expression of several genes in adipocytes. In this study, we demonstrate that 3T3-L1 adipocytes treated with PRL exhibit a reduction in adiponectin levels. Furthermore, we identified three putative STAT5 binding sites in the mouse adiponectin promoter and show that only one of these, located at -3809, binds nuclear …

Influences On Effective Local Wildfire Mitigation Programs, Kimberly Ann Geaghan

LSU Master's Theses

The purpose of this research is to identify key components of community wildfire risk reduction programs and potential influences on the adoption of these program elements. Community wildfire programs have been developed to educate and encourage property owners to adopt “vegetation management” practices such as creating defensible space around structures, landscaping with fire-resistant plants, and removing potential wildfire fuels such as trees and shrubs. The analyses are based on a survey conducted by investigators from Louisiana State University in conjunction with the U.S. Forest Service. This survey was distributed to wildfire mitigation program managers listed on the National Wildfire Programs …

Photocatalytic Oxidation Of Ethanol Using Macroporous Titania, Gibert Merle Magpantay

LSU Master's Theses

Photocatalytic oxidation (PCO) using TiO2 is a potential means of remediating poor indoor air quality that is attributed to low levels of volatile organic compounds (VOC). In this work, ethanol is chosen as a simple compound representative of VOC’s. The aim of this research is to establish a baseline for the photocatalytic activity of TiO2 in ethanol PCO as well as the photonic efficiency of the photoreactor. The PCO conversion could then be enhanced by using photocatalyst having a macroporous structure. A flat plate photoreactor, UV light delivery and a flow system was designed in this work to accomplish ethanol …

We Believe In The Systems That Keep Us Alive, Ezra Kellerman

LSU Master's Theses

ABSTRACT We Believe In the Systems That Keep Us Alive is a body of work that uses parallels identified between writing and media critique of contemporary events. The parallels are labeled as four specific systems: nutritional, administrative, life-support, and nurturing. Through a combination of interactive and object based sculpture, each system is represented with visual metaphor and allegory to place the viewer in a direct and specialized paradox. Paradoxes audience members encounter are intended to illustrate to the audience what conflicts can arise by being included in a system where governing agency of any sort does not meet with individual …

Ethanol Production Using Continuous Multi-Staged Microbe Bioreactors: A Laboratory Study, William Bruce King

LSU Master's Theses

Alternative fuels are important for the United States to reduce their dependence on fossil fuels. Currently, ethanol is the only renewable fuel that is produced in commercial quantity. The demand for ethanol is increasing throughout the world. The production of ethanol is limited by the available feedstocks and processing technology. Corn is the primary feedstock for ethanol in the United States. It is processed in either the wet milling or dry milling process. Both processes use either the batch or continuous fermentors. Both batch and continuous systems have operational restrictions with maintaining a good growth of yeast and preventing contamination …

Poinsettias are the number one flowering potted plant in the U.S. and it is the most popular Christmas plant sold. Miniature roses have become an increasingly important flowering potted plant. However, growers must overcome production problems to produce a quality finished plant and avoid disease incidence. Supplemental calcium has been proven to increase the amount of good quality flowers and increase disease resistance. Silicon can increase plant growth and crop quality and decrease disease pressures. Two experiments were conducted on miniature rose cultivars ‘Sonya’ and ‘Alto.’ The objective of experiment 1 was to determine the effects of preharvest application of …

Revolutionizing Genomic Analyses: Mutation Analyses Using Novel Enzyme-Based Assays With Laser-Induced Fluorescence And Polymeric Microfluidic Devices As Electrophoretic Platforms, Rondedrick Deshaun Sinville

LSU Doctoral Dissertations

Polymer-based microelectrophoresis was investigated to analyze known (mutation detection) and unknown (mutation scanning) low-abundant mutations in genomic DNA with high diagnostic value for colorectal cancers. For our mutation detection assays, point mutations in the K-ras oncogene were identified using the ligase detection reaction (LDR). For the mutation scanning assay, which searches for sporadic mutations, an EndoV-LDR assay was utilized with mutations in the p53 tumor suppressor gene used as a model. A poly(methylmethacrylate), PMMA, microchip filled with a 4% linear polyacrylamide (LPA) gel was used to electrophoretically sort products formed from LDRs, which produced oligonucleotides <65 bp in length. Using microchip electrophoresis with the LPA, a 44 bp ligation product was resolved from a 100-fold molar excess of unligated primers (25 bp) in approximately 120 s, which was ~17 times faster than conventional capillary gel electrophoresis. In order to simplify the electrophoretic process and further reduce development time, the LDR products were sorted in the absence of the sieving gel using free solution conjugate electrophoresis (FSCE). FSCE incorporated polyamide “drag-tags” onto LDR primers, which provided DNA fragment mobilities in free solution that were dependent upon their size. LDR/drag-tagged (LDR-dt) products could be formed in a multiplexed format for mutant-to-wild-type ratios as low as 1 to 100 with single base resolution. Separations were conducted using capillary array electrophoresis (CAE) and PMMA microchips filled with only a TRIS buffer. Analysis times for the LDR-dt products were less than 11 min using CAE and ~85 s for PMMA microchips with high reproducible migration times within and between microchips. PMMA-based microchips were also evaluated for the identification of sporadic mutations using an endonuclease V – LDR (Endo V/LDR) technique. Endo V cleaves heteroduplexed DNA one base 3’ of single-base mismatched sites as well as nicking DNA at some matched sites as LDR reseals miscleaved sites to reduce false positive signals. Results suggested that Endo V/LDR products from p53 mutations could be successfully separated and detected using a PMMA microfluidic chip filled with a sparsely cross-linked replaceable polyacrylamide gel in less than 6 min, which was approximately 10-fold shorter compared to CAE.

Neonatal Respiratory Virus Infection Shapes Pulmonary Function In Adult Mice, Dahui You

LSU Doctoral Dissertations

Respiratory syncytial virus (RSV) and influenza are the two most common causes of acute lower respiratory tract infections in infants. Epidemiological data suggest that both severe RSV and influenza infections during infancy are associated with long-term pulmonary function abnormalities. Despite of the severe burdens of RSV and influenza infections in infants, no efficacious vaccines are available for RSV and the current vaccine strategy for influenza is inconvenient due to the fact that vaccines are made annually based on the prediction of circulating strains in the next season. New strategies in vaccine development have been slow to arrive partly due to …

The Songs Of Black (Women) Folk: Music, Politics, And Everyday Living, Rasheedah Quiett Jenkins

LSU Doctoral Dissertations

The field of folklore in general, but specifically Africana folklore studies can be enriched by greater analyses of Black female contributions. In this study, I position folk music as the primary interest and chosen location to acknowledge Black women’s participation from beyond the margins. My inquiry reveals folk music as a lens into the myriad ways in which Black women have translated vernacular traditions into a means to deconstruct the master narrative as well as interrogate racist patriarchy. Specifically, this study examines how Nina Simone, Tracy Chapman, and Lauryn Hill have appropriated the folk aesthetic as a vehicle for social …

Reservoir Characterization Using Seismic Inversion Data, Subhash Kalla

LSU Doctoral Dissertations

Reservoir architecture may be inferred from analogs and geologic concepts, seismic surveys, and well data. Stochastically inverted seismic data are uninformative about meter-scale features, but aid downscaling by constraining coarse-scale interval properties such as total thickness and average porosity. Well data reveal detailed facies and vertical trends (and may indicate lateral trends), but cannot specify intrawell stratal geometry. Consistent geomodels can be generated for flow simulation by systematically considering the precision and density of different data. Because seismic inversion, conceptual stacking, and lateral variability of the facies are uncertain, stochastic ensembles of geomodels are needed to capture variability.

A Rhetoric Of Existentialism, Zachary Gershberg

LSU Doctoral Dissertations

Existentialism is often viewed as a morbid philosophy but adapting it to a rhetorical framework reveals a consistent interest in the ontological function of communication. The exchange of discourse and symbols is what ties humans together and existentialism examines the meaning that abounds in life as opposed to attempting to discover the meaning of life. As a rhetorical construct, existentialism provides a critical and unique view of agency and edification as a method of rhetorical practice.

From The Mountains To The Podium: The Rhetoric Of Fidel Castro, Brent C. Kice

LSU Doctoral Dissertations

This dissertation examines the rhetoric utilized by Fidel Castro that Castro used in order to maintain his tenure as the sole leader of Cuba for almost 50 years. Castro employs identification through division with an enemy, and he is able to perpetuate this division through an ongoing, dynamically perceived narrative. This narrative takes shape in the form of “the revolution,” a rhetorical construction designed to create a collective Cuban identity, which, in turn, is furthered through ideology by Castro’s elimination of competing points of views. Castro’s unique role as narrator has allowed him to adapt to events and maintain this …
