Tracing The Development Of Willie Stark And Its Place In American Opera, Betsy Marie Uschkrat

LSU Doctoral Dissertations

Highly praised American composer Carlisle Floyd (b. 1925), well known for his musical dramas Susannah (1955) and Of Mice and Men (1970), wrote Willie Stark (1981), commissioned by the Kennedy Center for the Performing Arts and later Houston Grand Opera. Floyd’s libretto and musical score was based upon Robert Penn Warren’s Pulitzer Prize-Winning novel All The King’s Men. Despite the vast amount of publicity it received at the premiere, this opera has only occasionally been performed in the last 35 years. Chapter One discusses Carlisle Floyd’s creation of Willie Stark. Chapter Two discusses the workshop performance of the piece. Chapter …

Relay Selection Strategies For Multi-Hop Cooperative Networks, Hui Sun

LSU Doctoral Dissertations

In this dissertation we consider several relay selection strategies for multi-hop cooperative networks. The relay selection strategies we propose do not require a central controller (CC). Instead, the relay selection is on a hop-by-hop basis. As such, these strategies can be implemented in a distributed manner. Therefore, increasing the number of hops in the network would not increase the complexity or time consumed for the relay selection procedure of each hop. We first investigate the performance of a hop-by-hop relay selection strategy for multi-hop decode-and-forward (DF) cooperative networks. In each relay cluster, relays that successfully receive and decode the message …

Study Of Resistivity And Shear Wave Velocity As A Predictive Tool Of Sediment Type In Levee Foundation Soils, Louisiana Gulf Coast Levee System, Derek Stephen Goff

LSU Master's Theses

Geotechnical sediment type of levee foundation soils may be estimated by using cross-plots of shear-wave velocity and electrical resistivity for Louisiana levees. Best-fit polynomial models for estimating soil type in Japanese levees have been created using cross-plots of shear-wave velocity and electrical resistivity. A similar study or model for flood protection structures in the Mississippi River delta plain or other major river delta does not exist. We make the soil-type estimation model more relevant to the foundation soils in the Louisiana Coastal Zone by identifying silt in addition to sand and clay, and eliminating gravel as a dominant soil type. …

Silicon Fertilization In Rice:Establishment Of Critical Silicon Level And Its Impact On Availability Of Nutrients In Soils Of Louisiana, Wooiklee Sundayboy Paye

Molecular Simulation Study Of Oil Hydrocarbons, Dispersants And Other Organics In Atmospheric Air/Water Interfaces, Zenghui Zhang

LSU Doctoral Dissertations

The main objective of this dissertation is to study the interfacial properties of organic contaminants, in particular green leaf volatiles (GLVs), oil hydrocarbons [mainly intermediate-volatile organic compounds (IVOCs) and semi-volatile organic compounds (SVOCs)], as well as surfactant species (i.e. DOSS and Span 80) from Corexit dispersants at atmospheric air/water and air/seawater interfaces. All these compounds can significantly contribute to the formation of secondary organic aerosols (SOAs). Furthermore, our simulation work on IVOCs, SVOCs and Corexit surfactants, combining with experiments from the Valsaraj group, suggests that these compounds can be adsorbed on the surface of seawater droplets and aerosolized into the …

Ultrafast And Nonlinear Spectroscopy Of Colloidal Nanomaterials, Tony Eugene Karam

LSU Doctoral Dissertations

In the first part of this dissertation, the adsorption isotherms, resonance coupling, and fluorescence of molecular dyes on the surface of plasmonic nanoparticles are investigates. SHG is also used to investigate the growth of a silver shell on the surface of gold nanoparticles in real time. Additionally, gold-silver-gold core-shell-shell nanoparticles possess extinction peak wavelengths that can be controlled over the visible and near-infrared regions and enhanced photothermal effect. Transient absorption measurements determine that the phonon-phonon scattering lifetime is considerably faster in the core-shell-shell nanoparticles than in the gold nanospheres and gold nanorods, which contributes to the higher photothermal efficiencies. Transient …

Phylogeography Of Oculina Corals And Their Algal Symbionts: Insights Into The Origin And Expansion Of Oculina Patagonica In The Mediterranean, Karine Eliane Posbic Leydet

LSU Doctoral Dissertations

In a world of rapidly changing environmental conditions, species must effectively respond to their changing habitat or risk extinction. The goal of my dissertation is to elucidate the origins and mechanisms underlying the recent successful population expansion of the invasive coral Oculina patagonica in the Mediterranean Sea. To do this, I have utilized nuclear markers and next-generation sequencing data for the coral host and its algal symbiont as well as environmental data. Although only recently first described from the waters of the Mediterranean, genetic, historical demographic, and fossil evidence suggests that O. patagonica has not been anthropogenically introduced from the …

Role Of An Adenylyl Cyclase Isoform In Alcohol's Effect On Cyclic Amp Regulated Gene Expression In Mammalian Cells, Rebecca Ann Hill

LSU Doctoral Dissertations

Research suggests that the cyclic AMP (cAMP) signaling pathway including CREB-CRE regulated expression of various genes is implicated in the predisposition to and development of alcoholism in humans. Alcohol also induces changes in inflammatory and immune responses; these changes increase the incidence of pneumonias and other infections, which can negatively affect recovery from infections. Cyclic AMP (cAMP) is known for its immunosuppressive effects and is also required for proper development of the immune system. Previous work in our laboratory has demonstrated that ethanol enhances the activity of adenylyl cyclase (AC) in an isoform-specific manner; type 7 AC (AC7) is most …

The Spirituality Of Faith In The Gospel Of Matthew (Chapter In Matthew And Mark Across Perspectives), Nijay Gupta

Faculty Publications - Portland Seminary

Excerpt: "In this essay, I wish to pay respect to Dr. Barton's important contribution to the theological study of the Gospels by looking at the Gospel of Matthew with a similar interest in the First Gospel's spirituality. In his chapter on Matthew, Barton rightly notes Matthew's interest in discipleship, righteousness, purity/integrity, and radical love. To this we will add Matthew's interest in 'faith'. In the study of the Synoptic Gospels in particular, despite the ubiquity of the language of faith, there has been little study of this subject. When it comes to the spirituality of the Gospels, though, there can …

Cb1 Receptor Antagonism Blocks Stress-Potentiated Reinstatement Of Cocaine Seeking In Rats, Jayme R. Mcreynolds, Elizabeth M. Doncheck, Oliver Vranjkovic, Geoffrey S. Ganzman, David A. Baker, Cecilia J. Hillard, John R. Mantsch

Biomedical Sciences Faculty Research and Publications

Rationale

Under some conditions, stress, rather than directly triggering cocaine seeking, potentiates reinstatement to other stimuli, including a subthreshold cocaine dose. The mechanisms responsible for stress-potentiated reinstatement are not well defined. Endocannabinoid signaling is increased by stress and regulates synaptic transmission in brain regions implicated in motivated behavior.

Objectives

The objective of this study was to test the hypothesis that cannabinoid type 1 receptor (CB1R) signaling is required for stress-potentiated reinstatement of cocaine seeking in rats.

Methods

Following i.v. cocaine self-administration (2 h access/day) and extinction in male rats, footshock stress alone does not reinstate cocaine seeking but reinstatement is …

Persuasive Strategies In A Chauvinistic Religious Discourse: The Case Of Women's Ordination, Eun-Young Julia Kim

Faculty Publications

Currently one of the most divisive issues in some Christian communities centers on women’s ordination. This study critically analyzes a religious discourse which defends and justifies the Southern Baptist Convention’s opposition to women’s ordination by using a sociocognitive approach as an underlying theoretical framework. The analysis aims to illustrate how a religious text both assumes and tries to formulate unified mental models to control the beliefs of the audience and promulgate dominance by assigning sovereign values to certain interpretations so that readers will understand certain texts as they see them. In doing so, the current study also hopes to demonstrate …
