Decentralized Scheduling For Many-Task Applications In The Hybrid Cloud, Brian Lyle Peterson Jan 2017

Decentralized Scheduling For Many-Task Applications In The Hybrid Cloud, Brian Lyle Peterson

LSU Doctoral Dissertations

While Cloud Computing has transformed how we solve many computing tasks, some scientific and many-task applications are not efficiently executed on cloud resources. Decentralized scheduling, as studied in grid computing, can provide a scalable system to organize cloud resources and schedule a variety of work. By measuring simulations of two algorithms, the fully decentralized Organic Grid, and the partially decentralized Air Traffic Controller from IBM, we establish that decentralization is a workable approach, and that there are bottlenecks that can impact partially centralized algorithms. Through measurements in the cloud, we verify that our simulation approach is sound, and assess the …

Characterization Of Dehalogenimonas Strains From A Louisiana Superfund Site That Reductively Dehalogenate Polychlorinated Alkanes, Trent Anthony Key Jan 2017

Characterization Of Dehalogenimonas Strains From A Louisiana Superfund Site That Reductively Dehalogenate Polychlorinated Alkanes, Trent Anthony Key

LSU Doctoral Dissertations

The research described in this dissertation was aimed at expanding understanding of the diversity and functional roles of microorganisms able to anaerobically transform chlorinated compounds. During the course of the research, a novel strictly anaerobic bacterial isolate originating from chlorinated solvent contaminated groundwater at a Superfund Site in south Louisiana (USA) was characterized. Phylogenetic analysis based on 16S rRNA gene sequencing placed the newly isolated strain, designated as NSZ-14 T, within the genus Dehalogenimonas but within a separate lineage from previously described species. Like previously described species within the genus Dehalogenimonas (i.e., D. lykanthroporepellens and D. alkenigignens), strain NSZ-14T was …

Remembering In Spite Of All: The Construction Of Collective Memory Of State Terrorism In Mexico, Argentina, And Chile, Telba Espinoza-Contreras

LSU Doctoral Dissertations

This dissertation seeks to contribute to the understanding of the formation of collective memory of State violence in Argentina, Chile, and Mexico. By comparing these three cases, I pursue to discern how citizens can challenge the silence and amnesia that the groups in power want to impose on society after a period of State terrorism. In order to examine the process of formation of collective memory, this dissertation highlights two important figures from which citizens have been able to build counter-hegemonic narratives, that is, los exiliados and los desaparecidos. I will highlight how they become lenses through which citizens can …

Improved Protein Characterizations Using Ionic Liquids: Page And Maldi-Ms, Punprabhashi Vidanapathirana Jan 2017

Improved Protein Characterizations Using Ionic Liquids: Page And Maldi-Ms, Punprabhashi Vidanapathirana

LSU Doctoral Dissertations

Protein separation by polyacrylamide gel electrophoresis (PAGE) and identification by matrix assisted laser desorption ionization-mass spectrometry (MALDI-MS) are primary tools of protein analysis. In these techniques, surfactants are used in protein sample preparation in order to enhance the protein solubility. Conventional surfactants have shown limitations in protein analysis due to the structural complexity of proteomes, resulting in low resolution. The research goal of this dissertation is to address some of these limitations by applying novel cationic ionic liquid surfactants (ILS), N-alkyl-4-methyl pyridinium bromide (CnPBr where n=4, 8, 11). The ILS would be suitable candidates to be used in PAGE protein …

The Roles Of Avr4 In Fungal Virulence,Cercosporin Biosynthesis And Its Potential Use In Host Induced Gene Silencing For Controlling Cercospora Leaf Blight Disease Of Soybeans, Josielle Santos Rezende Jan 2017

The Roles Of Avr4 In Fungal Virulence,Cercosporin Biosynthesis And Its Potential Use In Host Induced Gene Silencing For Controlling Cercospora Leaf Blight Disease Of Soybeans, Josielle Santos Rezende

LSU Doctoral Dissertations

The AVR4 effector, secreted by Cladosporium fulvum, has been demonstrated to be involved in pathogen virulence. Recent studies further demonstrated that Avr4 is highly conserved among several Cercospora species, indicating a potential important role of this gene in fungal virulence. Therefore, investigation to determine whether this fungal effector gene is present in Cercospora cf. flagellaris (previously known as C. kikuchii), the causal agent of soybean cercospora leaf blight (CLB) disease, and whether it plays any role in CLB disease development, is of great interest. In the present study, the Avr4 gene from C. cf. flagellaris was cloned and mutants lacking …

Organizational Misconduct Within The National Collegiate Athletic Association, Khirey Bennie Walker Jan 2017

Organizational Misconduct Within The National Collegiate Athletic Association, Khirey Bennie Walker

LSU Doctoral Dissertations

Prior research on organizational misconduct within intercollegiate athletics focuses on the penalties administered by the NCAA and types of violations committed by member institutions, rather than the engagement of misconduct and the role of the NCAA as a social-control agent. Consequently, the purpose of this dissertation is to analyze the relationship between social-control agents and potential wrongdoers (i.e., organizations), in addition to how the relationship affects the evolving line separating right from wrong. A three-paper multiple method examination has been conducted, including a historical analysis of NCAA enforcement, a qualitative framing analysis on the detailing of NCAA major infractions to …

"Leave All That You Have, That You May Take All:" What Hugo Distler's Totentanz Reveals About His Life And Music, Alison Elizabeth Allerton Jan 2017

"Leave All That You Have, That You May Take All:" What Hugo Distler's Totentanz Reveals About His Life And Music, Alison Elizabeth Allerton

LSU Doctoral Dissertations

Hugo Distler (1908-1942) has been described as the most important composer of Protestant Church music in Germany in the early twentieth century—a remarkable epithet given that he was a professional church musician and composer for only about twelve years before his life was abruptly ended with his suicide in 1942. Though he is more well-known in Germany, in the United States public perception of Distler is often limited to two basic “facts:” (1) he is a neo-Baroque composer whose works emulate Heinrich Schütz, and (2) his suicide was an act of resistance against the hated National Socialist regime. This study …

Analytical Solutions And Multiscale Creep Analysis Of Functionally Graded Cylindrical Pressure Vessels, Jasem Amjad Ahmed Jan 2017

Analytical Solutions And Multiscale Creep Analysis Of Functionally Graded Cylindrical Pressure Vessels, Jasem Amjad Ahmed

LSU Doctoral Dissertations

This study deals with the time-dependent creep analysis of functionally graded thick-cylinders under various thermal and mechanical boundary conditions. Firstly, exact thermoelastic stress, and iterative creep solutions for a heat generating and rotating cylindrical vessel made of functionally graded thermal and mechanical properties are proposed. Equations of equilibrium, compatibility, stress-strain, and strain-displacement relations are solved to obtain closed-form initial stress and strain solutions. It is found that material gradient indices have significant influences on thermoelastic stress profiles. For creep analysis, Norton’s model is incorporated into rate forms of the above-mentioned equations to obtain time-dependent stress and strain results using an …

Bonaparte's Dream: Napoleon And The Rhetoric Of American Expansion, 1800-1850, Mark Ehlers Jan 2017

Bonaparte's Dream: Napoleon And The Rhetoric Of American Expansion, 1800-1850, Mark Ehlers

LSU Doctoral Dissertations

Between 1800 and 1850, the United States built a continental empire that stretched from the Atlantic seaboard to the Pacific Ocean. As scholars have come to realize over the past three decades, this expansion was not a peaceful movement of American settlers into virgin wilderness. Instead, it involved the conquest and subjugation of diverse peoples in Louisiana, Florida and the northern provinces of Mexico, and forced the United States to interact aggressively with the European empires of Great Britain, France, Spain, and eventually Mexico. My work helps to explain how Americans in the early republic reconciled this militant expansion with …

Sediment Transport And Slope Stability In The Northern Gulf Of Mexico, Jeffrey Blake Obelcz Jan 2017

Sediment Transport And Slope Stability In The Northern Gulf Of Mexico, Jeffrey Blake Obelcz

LSU Doctoral Dissertations

Sediment transport and slope stability are fundamental organizing agents of the geological record. These processes have been extensively studied along the northern margin of the Gulf of Mexico basin for both basic and applied purposes, but our knowledge of them is limited by the spatial and temporal sampling capabilities of traditional geologic oceanographic surveying tools such as coring, single-beam echosounders, and sidescan sonar. This dissertation seeks to update the state of knowledge regarding northern Gulf of Mexico sediment transport and slope stability from annual to millennial timescales, primarily using relatively high-resolution acoustic geophysical tools such as swath bathymetric echosounders and …

Deterritorializing Dichotomies In Teacher Induction: A (Post)Ethnographic Study Of Un/Becoming An Elementary Science Teacher, Maria Ferris Greene Wallace Jan 2017

Deterritorializing Dichotomies In Teacher Induction: A (Post)Ethnographic Study Of Un/Becoming An Elementary Science Teacher, Maria Ferris Greene Wallace

LSU Doctoral Dissertations

Un/becoming an elementary science teacher is a dynamic phenomenon, yet the process is often intentionally limited to several taken-for-granted assumptions in research on science teacher induction. Inherent to research on beginning science teacher induction is also the construction of certain truths beginning science teachers, science teacher educators, and researchers think, feel, and live. This study complicates prevailing truths shaping notions of beginner, novice, induction, and traditions of inquiry as an ethicopolitical commitment to those implicated. In doing so, this study illuminates more expansive ways science teacher educators and those studying induction might study and understand the experiences of beginning science …

Maori Preserved Heads: A Legal History, Robert K. Paterson Jan 2017

Maori Preserved Heads: A Legal History, Robert K. Paterson

All Faculty Publications

For the first three decades of the nineteenth century New Zealand remained untouched by outside law. Foreign contacts mostly involved visits by traders, whalers, and missionaries. The latter sought to discourage the Maori practice of tattooing (ta moko), while the former quite soon began to see opportunities for trade in preserved tattooed heads. Early accounts of New Zealand described these heads and their mode of preservation. Ob-servers noted that both the heads of enemy warriors slain in battle, along with those of deceased chiefs and others of high rank, were preserved. The process involved the removal of interior soft tissue …

The Role Of Ethics Online And Among Social Media Designers, Meredith James Jan 2017

The Role Of Ethics Online And Among Social Media Designers, Meredith James

Schnitzer School of Art + Art History + Design Faculty Publications and Presentations

As communication designers, our roles have changed greatly with the technological advancements of the Internet and social media. With these vastly changing roles are equal (and often problematic) demands on designers to act as ethical interventionists. In specific, designers are more and more frequently finding themselves in roles of arbitration and decision-making surrounding ethical concerns. Such decisions span everything from what is to be considered “allowable content” (breastfeeding, for example) to deciding how our devices respond to crisis (Miner, et al., 2016). I intend to present several case studies of designers placed in authority positions centered around ethics and new …

Using Blog Comments As Feedback To Promote The Metacognitive Development Of Creativity, Mark Mcmahon, Heather Joseph Jan 2017

Using Blog Comments As Feedback To Promote The Metacognitive Development Of Creativity, Mark Mcmahon, Heather Joseph

Research outputs 2014 to 2021

Creativity can be viewed, not just as a set of skills and strategies, but as an overarching metacognitive skill that integrates a range of subordinate generic skills. Key to developing creativity is to engage in a cycle of ideation, reflection and adjustment, within a feedback rich environment. Blogs have the ability to garner external comments that can prompt these processes. Case study research was undertaken to explore what forms of feedback promote metacognitive development and how those forms can best be elicited within a blog. Findings indicated that blog comments can motivate, provide information, enhance quality and promote reflection, and …

Valuing Users Of Needle Syringe Exchange Programs: Design Approaches Within The Healthcare Sector, Samantha Pekaar, Hanadi Haddad Jan 2017

Valuing Users Of Needle Syringe Exchange Programs: Design Approaches Within The Healthcare Sector, Samantha Pekaar, Hanadi Haddad

Research outputs 2014 to 2021

Injecting drug users are among the most marginalised and stigmatised groups in society. This is a wicked problem exacerbated by multifaceted assumptions, misconceptions, and stereotypes surrounding injecting drug users. Stigmatisation results in injecting drug users being frequently denied basic human rights and subjected to severe social isolation (AIVL, 2003). Human-centered research approaches are particularly pertinent when conducting research in healthcare. The application of design approaches to define and address the perceived issues can result in more empathic and relevant designed outcomes (see Clarkson et al., 2010; Lamb, Zimring, Chuzi, & Dutcher, 2010; Loscin & Nagji, 2009; Razzouk & Shutre, 2012; …

Anaemia Of Chronic Kidney Disease: What We Know Now, Anoushka R. Krishnan, Debbie Trinder, Anita C. G. Chua, Aron Chakera, Grant A. Ramm, John K. Olynyk

Research outputs 2014 to 2021

Our understanding of the pathophysiology of the anaemia of chronic kidney disease (CKD) has improved considerably in the last decade with the discovery of the iron regulatory peptide hepcidin. Reduced clearance of hepcidin and the presence of a chronic inflammatory state contribute to elevated hepcidin levels in kidney disease. The recent discovery of the various factors and signalling pathways regulating hepcidin has opened up an exciting avenue for research into the development of newer agents that could treat anaemia of CKD. This review highlights our current understanding of iron metabolism in health, the regulators of hepcidin, issues associated with the …

Drilling Reconfigurable Machine Tool Selection And Process Parameters Optimization As A Function Of Product Demand, Ana Vafadar, Kevin Hayward, Majid Tolouei-Rad

Research outputs 2014 to 2021

Special purpose machines (SPMs) are customized machine tools that perform specific machining operations in a variety of production contexts, including drilling-related operations. This research investigates the effect of optimal process parameters and SPM configuration on the machine tool selection problem versus product demand changes. A review of previous studies suggests that the application of optimization in the feasibility analysis stage of machine tool selection has received less attention by researchers. In this study, a simulated model using genetic algorithm is proposed to find the optimal process parameters and machine tool configuration. During the decision-making phase of machine tool selection, unit …

Over-Provision Of Discretionary Foods At Childcare Dilutes The Nutritional Quality Of Diets For Children, Ruth M. Wallace, Leesa N. Costello, Amanda Devine Jan 2017

Over-Provision Of Discretionary Foods At Childcare Dilutes The Nutritional Quality Of Diets For Children, Ruth M. Wallace, Leesa N. Costello, Amanda Devine

Research outputs 2014 to 2021

The childcare setting can significantly influence the lifelong eating habits and health outcomes of children.It is ideal for health-promoting interventions that optimise the provision of nutritious food and nutrition education. Unfortunately, these interventions are neither offered nor promoted in many childcare settings. Recent studies have indicated an increased risk of overweight/obesity with childcare attendance, which if present in early life is associated with increased risk of chronic disease and reduced psychological wellbeing.

The Patient Survey Programme: Transforming The Patient Experience In Irish Healthcare, Vivienne Byers, D. Fahey, C. Mullins, C. Roe

Articles

For more than a decade, health policy in Ireland has pushed the centrality of the patient in the delivery and management of healthcare services, including the development of a National Strategy for Service User Involvement in the Health Service 2008–2013 (Health Service Executive, 2008). More recently, the need to provide a ‘patientcentred’ (Department of Health, 2012, 2013, 2014) or ‘person-centred’ (Department of Health, 2016) service has been a guiding principle of health policy documents. The National Service Plan 2017 (Health Service Executive, 2016) also outlines the importance of increasing the rates of service user engagement and feedback across the health …

AndréS Segovia’S Unfinished Guitar Method: Placing His “Scales” In Historical Context, Andreas Stevens Jan 2017

AndréS Segovia’S Unfinished Guitar Method: Placing His “Scales” In Historical Context, Andreas Stevens

Soundboard Scholar

For over sixty years, guitarists of my generation have been familiar with the so-called Segovia Scales—the systematic scale fingerings advocated by the Andalusian maestro. They have been an influential—some might say a definitive—bestseller since their first USA publication in 1953. Countless guitar students have incorporated them into their daily practice routines. For the publisher, Columbia Music, they seem to be the goose that laid the golden egg. Are they everything that Segovia wanted them to be? Two books of recent date on guitar technique attest to their enduring value and relevance. Thomas Offermann wrote in 2015: “The fingerings of the …

A Newly Discovered Letter Of 1827 By Fernando Sor, Erik Stenstadvold Jan 2017

A Newly Discovered Letter Of 1827 By Fernando Sor, Erik Stenstadvold

Soundboard Scholar

This article discusses a hitherto unknown letter, written by Sor in Saint Petersburg in April 1827. It provides new insight into the publishing and personal relationship between Sor and his Paris publisher, Antoine Meissonnier, to whom the letter was addressed. We learn about three airs with variations Sor was busy composing at the time; he was particularly pleased with the variations Meissonnier later published as op. 30. The letter also mentions some unknown Sor works, including a book of drafts at Málaga, and it reveals that Meissonnier had published, without Sor’s knowledge, music that he had received from sources other …
