Data-Aware Workflow Scheduling In Heterogeneous Distributed Systems, Dengpan Yin Jan 2011

Data-Aware Workflow Scheduling In Heterogeneous Distributed Systems, Dengpan Yin

LSU Doctoral Dissertations

Data transferring in scientific workflows gradually attracts more attention due to large amounts of data generated by complex scientific workflows will significantly increase the turnaround time of the whole workflow. It is almost impossible to make an optimal or approximate optimal scheduling for the end-to-end workflow without considering the intermediate data movement. In order to reduce the complexity of the workflow-scheduling problem, most researches done so far are constrained by many unrealistic assumptions, which result in non-optimal scheduling in practice. A constraint imposed by most researchers in their algorithms is that a computation site can only start the execution of …

Development Of A Monte Carlo Based Correction Strategy For A Tg-43 Based Brachytherapy Treatment Planning System To Account For Applicator Inhomogeneities, Bobby Chon Mathews

LSU Master's Theses

Purpose: The purpose of this work was to investigate the use of pre-calculated Monte Carlo (MC) ovoid and source-based attenuation-correction factors that would correct a commercially-available brachytherapy treatment planning system (TPS) generated plan in order to account for any dosimetric effects due to the presence of intracavitary brachytherapy (ICBT) applicators during treatment delivery. Methods: A MC model of an ICBT CT-MR compatible ovoid applicator set was confirmed utilizing radiochromic film (RCF). MC was used to simulate dose distributions resulting from eight source-dwell-positions within the ICBT applicator. Also, the American Association of Physicist in Medicine Task Group 43 Report (AAPM TG-43) …

Soft Sediment Relay Zones: A High Resolution Seismic Survey Livingston Parish, Louisiana, Erin T. Elliott Jan 2011

Soft Sediment Relay Zones: A High Resolution Seismic Survey Livingston Parish, Louisiana, Erin T. Elliott

LSU Master's Theses

The southern coast of the United States, bordering the Gulf of Mexico, is home to several down-to-the-south, listric, normal fault systems striking parallel to the coast. One of these, the Baton Rouge–Tepetate Fault System located in southern Louisiana, consists of a series of near-surface, reactivated growth faults and relay ramps– a broad area of ductile strain, with contemporaneous sedimentation. Evidence of recent fault and relay ramp movement is seen in surficial fault line scarps and offset roads. This thesis utilizes two near-surface (<500 >m), high-resolution (10 - 300 Hz), continuous seismic reflection profiles (360 m and 480 m long, 3 …

Catalytic Process For The Conversion Of Synthesis Gas To Ethanol For Use As An Alternative Fuel, Nitin Kumar Jan 2011

Catalytic Process For The Conversion Of Synthesis Gas To Ethanol For Use As An Alternative Fuel, Nitin Kumar

LSU Doctoral Dissertations

Higher alcohols are increasing as a proportion of the transportation fuel market, and can be used as neat fuels, or as blends with conventional fuels. For a number of reasons, these C2+-alcohols will be of interest in the foreseeable future. Large-scale production of higher alcohols will likely be carried out via syngas, which can be produced from a number of feedstocks, including coal, natural gas and biomass. Rhodium-based catalysts have been found to be the most active/selective for higher alcohols. However, the literature shows that the yields of C2+-alcohols that can be achieved with current catalysts, even the most active/selective, …

From Global To Polycentric Climate Governance, Daniel H. Cole Jan 2011

From Global To Polycentric Climate Governance, Daniel H. Cole

Articles by Maurer Faculty

Global governance institutions for climate change, such as those established by the United Nations Framework Convention on Climate Change and the Kyoto Protocol, have so far failed to make a significant impact on greenhouse gas emissions. Following the lead of Elinor Ostrom, this paper offers an alternative theoretical framework for reconstructing global climate policy in accordance with the polycentric approach to governance pioneered in the early 1960s by Vincent Ostrom, Charles Tiebout, and Robert Warren. Instead of a thoroughly top-down global regime, in which lower levels of government simply carry out the mandates of international negotiators, a polycentric approach provides …

Rights, Needs, And The Creation Of Ethical Community, Natalie Susan Gaines Jan 2011

Rights, Needs, And The Creation Of Ethical Community, Natalie Susan Gaines

LSU Doctoral Dissertations

Despite a half-century of dominance by the rights discourse, the supremacy of rights in theories of human obligation has recently come under attack from political theorists. Though scholars have questioned the ability of rights to explain satisfactorily the responsibility we have for the well-being of others, there are few viable alternatives offered. In this dissertation, I argue that a theory of needs provides a better explanation of the intellectual and moral foundations of obligation. Human need is deeply rooted in subjective potentiality, but studies in human psychology have also provided an increasingly universal picture of the needs human beings experience. …

Framing Empire: Victorian Literature, Hollywood International, And Postcolonial Film Adaptation, Jerod Ra'del Hollyfield Jan 2011

Framing Empire: Victorian Literature, Hollywood International, And Postcolonial Film Adaptation, Jerod Ra'del Hollyfield

LSU Doctoral Dissertations

This dissertation examines how adaptations of Victorian literature made in Hollywood by postcolonial filmmakers contend with the legacy of British imperialism and Hollywood’s role as a multinational corporate entity. Highlighting the increased number of postcolonial filmmakers adapting Victorian literature in Hollywood, the project demonstrates how film adaptation has become a strategy for, in the words of Salman Rushdie, “writing back” to imperial powers. Placing such adaptations of Victorian literature within the tradition of postcolonial rewritings of classic British texts, I bridge fidelity criticism, the auteur theory, and contrapuntal readings of source texts with studies of political economy in order to …

The Contribution Of Implicit Stereotypes To The Overrepresentation Of African Americans In The Special Education Category Of Emotional Disturbance, Tai A. Collins Jan 2011

The Contribution Of Implicit Stereotypes To The Overrepresentation Of African Americans In The Special Education Category Of Emotional Disturbance, Tai A. Collins

LSU Master's Theses

The overrepresentation of African Americans in special education is a problem that has plagued the field since its inception, yet very little progress has been made in alleviating the issue. The problem is especially troubling because of the host of negative outcomes associated with special education in general, as well as placing African American students into special education specifically. The current study sought to examine the contribution of implicit racial stereotypes to the overrepresentation problem. Participants were randomly assigned to conditions where they viewed vignettes about either an African American or Caucasian problem student, after which they completed a questionnaire …

The Story Of Kleppe V. New Mexico: The Sagebrush Rebellion As Un-Cooperative Federalism, Robert L. Fischman, Jeremiah Williamson Jan 2011

The Story Of Kleppe V. New Mexico: The Sagebrush Rebellion As Un-Cooperative Federalism, Robert L. Fischman, Jeremiah Williamson

Articles by Maurer Faculty

The story of Kleppe v. New Mexico dramatizes how assertion of federal power advancing national conservation objectives collided with traditional, local economic interests on public lands in the 1970s. This article connects that history with current approaches to natural resources federalism. New Mexico challenged the Wild Free-Roaming Horses and Burros Act, which diminished both state jurisdiction and rancher influence over public rangelands. In response, the Supreme Court resoundingly approved federal authority to reprioritize uses of the public resources, including wildlife, and spurred a lasting backlash in the West. Further legislation passed in the wake of Kleppe transformed this unrest into …

An Euler Solver For Nonlinear Water Waves Using A Modified Staggered Grid And Gaussian Quadrature Approach, Qi Fan Jan 2011

An Euler Solver For Nonlinear Water Waves Using A Modified Staggered Grid And Gaussian Quadrature Approach, Qi Fan

LSU Master's Theses

A structured, finite-volume Euler solver for non-hydrostatic, free surface flows is developed to simulate coastal nonlinear dispersive water waves. A semi-implicit projection method which splits the pressure term into hydrostatic and non-hydrostatic parts is employed. A vertically shifted, staggered grid is designed to accommodate a new Gaussian discharge calculator and to facilitate the enforcement of a non-hydrostatic free-surface boundary condition. The Gaussian discharge calculator on the shifted grid increases the dispersion accuracy compared to traditional approaches that calculate discharges on a regular staggered grid. Numerical results are presented to demonstrate the improvements of these methods.

An Examination Of Errors Of Coherence In Adolescent Sentence Combining, Ginger Gunter Collins Jan 2011

An Examination Of Errors Of Coherence In Adolescent Sentence Combining, Ginger Gunter Collins

LSU Doctoral Dissertations

Young adolescents should be able to write organized multi-paragraph compositions that develop a central idea and unfold in logical and sequential order, unified through the use of transitional words and phrases. In other words, the compositions should not just consist of a string of related sentences, but represent a dynamic text that has coherence. It is important that speech-language pathologists develop quick and reliable methods for assessing coherence to aid in making data driven decisions and progress monitoring consistent with principles of Responsiveness to Intervention. Yet, the holistic quality of coherence makes it difficult to assess, both within a composition …

Interpretation And Expressive Imagery In The Butterfly Lovers Violin Concerto On Double Bass: Transcribed By Yung-Chiao Wei, Min-Tzu Chao Jan 2011

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 …

A Survey Of Rudy Davenport's Byna: Life Songs Of A Southern Appalachian Woman Of Cherokee Indian Descent (A Chamber Work For Soprano, Piano, Oboe And Cello), Tiffany I. Bostic-Brown

LSU Doctoral Dissertations

Composer Rudy Davenport aims to create music that is more relatable than the atonal compositions often associated with 20th century composers. Inspired by his own Appalachian and Cherokee heritages, Davenport, in collaboration with librettist Delilah Elsen, developed his own musical genre called “Appalachian Romanticism”. This genre is evident in his work BYNA: Life Songs of a Southern Appalachian Woman of Cherokee Descent for Soprano, Piano, Oboe & Cello. The purpose of this study is to understand and describe Rudy Davenport’s view on 20th century composition. To obtain this information I interviewed Davenport posing questions about his biography and musical preferences, …

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 …
