Interpretation And Expressive Imagery In The Butterfly Lovers Violin Concerto On Double Bass: Transcribed By Yung-Chiao Wei, Min-Tzu Chao

LSU Doctoral Dissertations

The purpose of this research paper is to show the interpretation of the Chinese piece—The Butterfly Lovers Violin Concerto—through expressing imagery. The concerto is composed by Chen Gang (陳鋼) and He Zhan-hao (何占豪) in 1959. In 2004, Yung-Chiao Wei, a double bass professor at Louisiana State University transcribed the piece for double bass. It is a very useful repertoire for double bass players to experience Chinese music through the plot’s expressing imagery. The Chinese musical language is different from Western music language in the concept of pentatonic scale, tone color, and tempo. I believe that double bass players can effectively …

Essays On The Random Parameters Logit Model, Tong Zeng Jan 2011

Essays On The Random Parameters Logit Model, Tong Zeng

LSU Doctoral Dissertations

This research uses quasi-Monte Carlo sampling experiments to examine the properties of pretest and positive-part Stein-like estimators in the random parameters logit (RPL) model based on the Lagrange Multiplier (LM), likelihood ratio (LR) and Wald tests. First, we explore the properties of quasi-random numbers, which are generated by the Halton sequence, in estimating the random parameters logit model. We show that increases in the number of Halton draws influence the efficiency of the RPL model estimators only slightly. The maximum simulated likelihood estimator is consistent and it is not necessary to increase the number of Halton draws when the sample …

Costs And Benefits Of Induced Responses In Soybean, Amanda K. Accamando Jan 2011

Costs And Benefits Of Induced Responses In Soybean, Amanda K. Accamando

LSU Master's Theses

Herbivorous insects are known to negatively impact plant fitness, such that plants have evolved defense strategies to reduce the preference and performance of herbivores on those plants. However, a plant’s investment in defense may be costly when herbivores are absent from the environment. Defense traits that are induced only upon herbivory can mitigate costs associated with defense maintenance. Although costs and benefits of induced responses are generally assumed, empirical evidence for them is equivocal. We examined the fitness costs and benefits of jasmonic acid-induced responses by soybean (Glycine max L. Merr.) in the absence and presence of soybean loopers (Chrysodeix …

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’ …

Dyadic Meta-Accuracy In Leader-Member Exchanges: An Examination Of Antecedents And Relational Outcomes, Jared A. Ledoux Jan 2011

Dyadic Meta-Accuracy In Leader-Member Exchanges: An Examination Of Antecedents And Relational Outcomes, Jared A. Ledoux

LSU Doctoral Dissertations

Work organizations are inherently social entities, dependent upon the social interactions between supervisors and subordinates. This study examined the role of interpersonal processes within organizational settings, focusing upon subordinates‟ accuracy in judging their supervisors‟ impressions of the subordinates‟ personality. This phenomenon, dyadic meta-accuracy, is examined within exchange relationships between supervisors and subordinates, drawing upon Leader Member Exchange (LMX) theory and the metaperception literature. A theoretical framework proposed potential antecedents of subordinate meta-accuracy, including: communication frequency, physical proximity, psychological closeness, and trait visibility. In addition, subordinate meta-accuracy was proposed as a determinant of the relational quality between subordinate and supervisor and …

An African American Discourse Community In Black & White: The New Orleans Tribune, Kristi Richard Melancon Jan 2011

An African American Discourse Community In Black & White: The New Orleans Tribune, Kristi Richard Melancon

LSU Doctoral Dissertations

In An African American Discourse Community in Black & White: The New Orleans Tribune, an archival study of the first black-owned daily newspaper in the United States, I argue that the newspaper rhetorically constructed a literate African American discourse community worthy of citizenship and equal political rights within the public sphere of Reconstruction United States. Although contemporaneous media in the South depicted blacks as both unable to read and write and as culturally illiterate, I demonstrate how articles across the lifespan of the Tribune represented, as well as encouraged and enabled, multiple literacies within the African American community. I ultimately …

Climate Change Displacement And Global Governance: A Case Study Of Three Intergovernmental Organizations And The Conflict Between The Member States And Bureaucracy, Andrea C. S. Berringer

LSU Doctoral Dissertations

Climate change is a topic most often broached by environmental scientists and activists and its effects are discussed in terms of animal populations and atmospheric events. However, its direct effect on human life is yet to garner such attention. A changing climate will affect how people are able to use their environment, if at all. Sea level rise and desertification will force a shift in human habitation. How the world seeks to deal with this shift is yet to be seen. The global governance of climate change-induced displacement is currently at the stage of ad hoc development. Legal and conceptual …

"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 …

Analysis Of Major Hydrologic Events In Ascension Parish, La, Jessica Irene Mason

LSU Master's Theses

Ascension Parish is located in Southern Louisiana and is characterized by low slope and low elevation. This combination allows for much hydrologic storage during a flood event. Because Ascension Parish is one of the most rapidly growing areas in the United States, it is necessary to accurately predict the hydrologic and hydraulic properties of flow and accurately model them. Several processes within a hydrologic model greatly influence the output flow hydrographs so selecting correct methods and parameters is important. Transform methods describe how excess precipitation is transformed into runoff. There are several methods that can be used as a transform …

Modeling Effects Of Coupled Convection And Co2 Injection In Stimulating Geopressured Geothermal Reservoirs, Tatyana Plaksina Jan 2011

Modeling Effects Of Coupled Convection And Co2 Injection In Stimulating Geopressured Geothermal Reservoirs, Tatyana Plaksina

LSU Master's Theses

Geopressured geothermal brines are a vast geothermal resource in the US Gulf of Mexico region. In particular, geopressured sandstones near salt domes are potential sources of geothermal energy because salt diapirs with high thermal conductivities may pierce younger, cooler strata. These characteristics enhance transfer heat from older, hotter strata at the base of the diapir into shallower strata. Moreover, widespread geopressure in the Gulf region tends to preserve permeability, enhancing productivity. As an example, the Camerina A sand of South Louisiana was chosen as a geomodel for a numerical simulation study of effects of CO2 injection and coupled convection as …
