Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm Jan 2011

Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm

LSU Doctoral Dissertations

Core stability is a concept in the health and fitness professions which became popular in the early 1990s. Despite its popularity, core stability remains a generalized term, which is poorly understood and lacks a universal definition and gold standard assessment. This makes it difficult to identify the role of core stability in athletic injury prevention and performance. To better assess core stability, the objective for this dissertation was to construct a reliable core stability index using measurements which best define and evaluate core stability. The purpose of our first experiment was to introduce and determine the intra-tester reliability of clinical …

Agnolo Gaddi: Issues Of Patronage And Narrative In The Selection Of The True Cross Cycle At Santa Croce, Florence, Tracey Hirstius Barhorst Jan 2011

Agnolo Gaddi: Issues Of Patronage And Narrative In The Selection Of The True Cross Cycle At Santa Croce, Florence, Tracey Hirstius Barhorst

LSU Master's Theses

Agnolo Gaddi’s Legend of the True Cross fresco cycle in the sanctuary of Santa Croce, Florence, represents an unusual artistic program. Initiated by the Franciscans around 1388, Gaddi’s is the earliest monumental True Cross program; it set the standard for similar works into the sixteenth century. The objective of this thesis is to shed light on this unusual narrative sequence and the reasons for the selection of the True Cross legend as its subject matter. The unique choice for the narrative program provokes several questions: Why was it chosen? What purpose did it serve? What truths did it attempt to …

Use Of Condensed Tannins Supplementation And Inorganic Copper As Deworming Agents In Naturally Infected Ewes And Lambs, Moara De Santana Martins

LSU Master's Theses

Sheep production is an important socioeconomic activity for the small producers and it can represent their primary income source. Gastrointestinal parasites have become the principal limiting factor for this industry around the world, especially because of the anthelmintic resistance phenomenon that has been increasing worldwide. The negligent use of anthelmintics has been reported as the main factor in the development of resistance. Among the parasites that infect sheep, H. contortus is considered the most harmful and also the parasite responsible for the fastest development of nematode resistance in small ruminants. Due to the economic impact this parasite may bring upon …

Development And Validation Of Biomechanical Models To Quantify Horse Back Forces At The Walk In Three Horse Breeds, Laxmi Raghunandana Kaidapuram Jan 2011

Development And Validation Of Biomechanical Models To Quantify Horse Back Forces At The Walk In Three Horse Breeds, Laxmi Raghunandana Kaidapuram

LSU Master's Theses

Therapeutic horseback riding is a common component of physical therapy programs. Quantification of the horse back forces will provide vital information to match therapeutic riders with equine partners. To meet this medical need, a model to quantify the horse back forces from ground reaction forces was developed to test the hypothesis that the forces transferred to a static weight on the horse’s back can be predicted given horse breed and weight. Simultaneous, real time kinetic, kinematic, and back force data on a static weight were collected from 7 adult horses: 3 thoroughbreds, 3 quarter horses, and 1 paso fino. An …

An Aloha State Of Mind: Performing Hawaiian Cultural Identities, Kirsten E. Ogden Jan 2011

An Aloha State Of Mind: Performing Hawaiian Cultural Identities, Kirsten E. Ogden

LSU Doctoral Dissertations

There are many Hawaiian identities currently in effect. This dissertation explores several representative and contested Hawaiian identities, and how these identities develop through key performances, plays, and other representational practices by Hawaiians and by Locals. Due to its unique situation as one of only two U.S. states formerly with its own government, and as one of only two U.S. states not connected to the main land-mass of the United States, Hawaiian identity is complicated by multiple factors: sanitized historical constructions, sovereignty, intermingling ethnic identities, tourism, and reclaimed cultural practices. Additionally, Hawaiians as a native people hold a unique place in …

Structural And Functional Insights Of Human 5-Lipoxygenase, Nathaniel Carson Gilbert Jan 2011

Structural And Functional Insights Of Human 5-Lipoxygenase, Nathaniel Carson Gilbert

LSU Doctoral Dissertations

This work describes the structure of human 5-lipoxygenase (5-LOX) (Gilbert, Bartlett et al. 2011) and the techniques required to ascertain the structure. 5-LOX is a notoriously unstable enzyme with important biological functions. The human 5-LOX has been implicated in many disease states including asthma, atherosclerosis and cancer. Part of 5-LOX biology is the inherent instability of the enzyme, which is thought to help regulate the production of its pro-inflammatory products, the leukotrienes. Our objective was stabilizing the enzyme for in vitro studies without affecting catalytic fidelity. I was able to quantitate stabilizing and destabilizing point mutations of 5-LOX by thermal …

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). I …

Rapid Identification Of Oil Contaminated Soils Using Visible Near Infrared Diffuse Reflectance Spectroscopy, Somsubhra Chakraborty Jan 2011

Rapid Identification Of Oil Contaminated Soils Using Visible Near Infrared Diffuse Reflectance Spectroscopy, Somsubhra Chakraborty

LSU Doctoral Dissertations

Initially, 46 petroleum contaminated and non-contaminated soil samples were collected and scanned using visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) at three combinations of moisture content and pretreatment. The VisNIR spectra of soil samples were used to predict total petroleum hydrocarbon (TPH) content using partial least squares (PLS) regression and boosted regression tree (BRT) models. The field-moist intact scan proved best for predicting TPH content with a validation r2 of 0.64 and relative percent difference (RPD) of 1.70. Those 46 samples were used to calibrate a penalized spline (PS) model. Subsequently, the PS model was used to predict soil TPH …

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 Jan 2011

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. …

Measurement Of Spatial Variation Of Density Of Compacted Powder Using Synchrotron Microtomography, Yi Yang Jan 2011

Measurement Of Spatial Variation Of Density Of Compacted Powder Using Synchrotron Microtomography, Yi Yang

LSU Master's Theses

This research considers density change in powder metallurgy when compacting a powder blend in a die. In order to provide insights into particle behavior during compaction, atomized aluminum powders with an average particle size of 100 µm were used in two different compaction configurations. The compaction dies are cylindrical in shape: compaction configuration I displays an upper punch, a die, a lower punch, and a spacer. Compaction configuration II displays an upper punch, two dies, a lower punch, and a spacer with different geometry. The Synchrotron Microtomography scans were conducted on both compaction configurations. For compaction configuration I, the scan …

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 …
