Characterization And Utilization Of Rice Defense Associated With Partial Resistance To Bacterial Panicle Blight: An Emerging Rice Disease Problem In The Southeastern United States, Bishnu Kumar Shrestha Jan 2011

Characterization And Utilization Of Rice Defense Associated With Partial Resistance To Bacterial Panicle Blight: An Emerging Rice Disease Problem In The Southeastern United States, Bishnu Kumar Shrestha

LSU Master's Theses

Rice is a staple food for much of the world’s growing population. Rice production is limited by a number of abiotic and biotic factors. These factors have direct effects on food security because less food is available to growing population. Bacterial panicle blight (BPB), caused by the bacterium Burkholderia glumae, is an emerging disease that causes grain rot, panicle discoloration, and unfilled grains in rice. Up to 70% of yield reduction has been reported in severely infected rice fields. No completely resistant rice cultivars have been identified, however, a medium-grain cultivar, Jupiter, showed a high level of partial resistance …

Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins Jan 2011

Assessing Attentional Bias And Cerebral Laterality In Specific Phobia Using A Dichotic Listening Paradigm, Whitney Shay Jenkins

LSU Master's Theses

Researchers have found fear to impact a variety of cognitive variables in individuals with specific phobia. Attentional bias is a cognitive variable that has received considerable attention in the specific phobia literature; however, the existing literature follows only one line of attentional bias—bias as encoded through images, words, or other content presented visually. This study aimed to expand on this area by assessing attention and cerebral laterality in individuals with specific phobia using a dichotic listening paradigm (i.e., via auditory means). Results indicated that participants with specific phobias do not significantly differ from controls in terms of the number of …

Vessel Manifest, Jessie Marie Hornbrook Jan 2011

Vessel Manifest, Jessie Marie Hornbrook

LSU Master's Theses

Vessel Manifest explores vessel forms and their pathways through time and experience. In using semiotic definitions to define the term vessel I investigate the ways in which it has become profound in my life. In seeking comfort and in searching for an explanation for the process of life and death, I look to the ways in which a vessel can manifest itself, physically, emotionally, mentally, and metaphysically. Memories of life spent on the water and theories and tenets of Tibetan Buddhist Philosophy are sewn together through images of physical vessels and abstract vessel forms. The large-scale intaglio prints incorporate multi-media …

Trials & Tributaries: Myth And Disaster In Southern Louisiana, Hannah March Campbell Sanders

LSU Master's Theses

Trials and Tributaries examines recent disasters occurring in southern Louisiana, interpreted through the Greek myths The Twelve Labors of Herakles. Mankind’s false sense of control over Louisiana’s resources leaves us vulnerable to nature’s powerful acts of reclamation: hurricanes, floods and the ground sinking beneath our feet. While researching the details and origins of The Twelve Labors, I found a plethora of similarities with local culture, politics and natural disasters. The characters in these narrative prints include hybrid monsters drawn from Greek mythology, which I have then further augmented with various forms of local south Louisiana fauna and contemporary political figures. …

I Can Has Thesis? A Linguistic Analysis Of Lolspeak, Jordan Lefler Jan 2011

I Can Has Thesis? A Linguistic Analysis Of Lolspeak, Jordan Lefler

LSU Master's Theses

Lolspeak, which I characterize as an internet dialect of English that is used in conjunction with images of cats, exhibits distinctive variations and patterns which differ from those of standard English. Lolspeak has influenced other language use and may have a significant impact on the English language, due in part to the internet’s role in the evolution of English (Crystal “Language and the Internet,” 2006:26-27). To approach this data, I created a multi-modal discourse transcription technique for analyzing Lolspeak utterances within the context of their images based on Grounded Theory (Glaser and Strauss “The Discovery of Grounded Theory” 2007:9).

Emotion And Rhetoric In Bioshock, Jason Liban Rose Jan 2011

Emotion And Rhetoric In Bioshock, Jason Liban Rose

LSU Master's Theses

In this paper, I tie four concepts together to form a defense both of videogames as art, and of rhetoric as a value-neutral tool of expression, that can be both positive and useful for society. (1) In the first chapter, I explain the Platonic view of rhetoric as an “empty knack” and how it differs from other accounts of rhetoric, ancient and modern. (2) In the second chapter I present a nuanced understanding of the role emotion plays in practical moral reasoning under a computational model of the mind, as described by Antonio Damasio’s neurological somatic marker theory in Descartes’ …

Nietzsche, Unconscious Processes, And Non-Linear Individuation, Damon Paul Mcgregor Jan 2011

Nietzsche, Unconscious Processes, And Non-Linear Individuation, Damon Paul Mcgregor

LSU Master's Theses

This thesis attempts to create an ontology of the self using Nietzsche’s concept of will-to-power forces, which operate in the individual unconsciously, leading to non-linear individuation resulting from responding or participating in chance events. Individuation results non-linearly because of Nietzsche’s claim that the “Deed has no doer” and that subjects and thoughts rely on fictitiously created causal chains, but that in actuality there are nothing but chance events and competing forces of nature which shape the individual into non-linear directions. The individual can only respond as creatively as possible to moments which arise, once loss of ultimate control is embraced. …

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks Jan 2011

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks

LSU Master's Theses

This thesis seeks to understand the emotional geographies of American garage sales, which I argue are liminal. Through a methodology of narrative surveys (open-ended questionnaires), mental maps, participant-observation, and interviews, I make the case that garage sales, through absent and/or present items, narratives, and exchanged histories, can reveal much in terms of identity, values, and cultural practices. These archives on the margins hold stories, artifacts, and performances of a distant or near past, giving geographers an innovative lens through which to explore the intricacies of materiality, place, and representation. This thesis provides a range of theoretical and practical perspectives on …

Transport Properties Of Nanometer-Sized Assemblies Through Nanofluidic Channels With Single Entity Electrical Detection, Franklin Ifeanyichukwu Uba

LSU Master's Theses

Recently, there have been reports on biological and solid-state nanopores that identify single biopolymers or their constituent monomers by analyzing changes in ionic current blockades when they block the flux of buffer ions while travelling through the nanopores. Nevertheless, there have been several limitations in their application, especially as DNA detectors; Poor confinement of the DNA strand within the nanopore (~0.1 % of a 10 kilobase (kb) DNA), poor signal sensitivity and random motion experienced by the DNA in solution that results in a large amount of noise in the signal. These have led to the development of nanochannel-based devices, …

Comparison Of Disk Diffusion, Agar Dilution, And Broth Microdiultion For Antimicrobial Susceptibility Testing Of Five Chitosans, Lin Jiang Jan 2011

Comparison Of Disk Diffusion, Agar Dilution, And Broth Microdiultion For Antimicrobial Susceptibility Testing Of Five Chitosans, Lin Jiang

LSU Master's Theses

Chitosan is a polysaccharide biopolymer with excellent biocompatibility, biodegradability, and low toxicity, which allows for potential wide applications. Recently, antimicrobial activities of chitosan against foodborne pathogens have been studied; many used disk diffusion to determine the activity. However, this method is unable to obtain minimal inhibitory concentrations (MICs), i.e., not quantitative. The objective of this study was to compare disk diffusion with agar dilution and broth microdilution, two quantitative methods used routinely in clinical laboratories, to determine MICs of chitosan against foodborne pathogens. Five chitosan compounds with molecular weights ranging between 43 and 1,100 kDa were tested against 36 representative …
