The Sports Appeal: Are Atheletics A Viable Academic Marketing Vehicle In Higher Education?, Reagan Thomas Chenevert Jan 2004

The Sports Appeal: Are Atheletics A Viable Academic Marketing Vehicle In Higher Education?, Reagan Thomas Chenevert

LSU Master's Theses

Universities are beginning to brand themselves. The days when the doors to higher-ed opened and students flooded into the classrooms are no more. Colleges have to find ways to separate themselves from each other in a noisy marketplace. Also there is a decline in newsroom resources for academic coverage, which leaves university marketers searching for ways to communicate their messages. However, universities have another available marketing outlet, which is not seeing declining media attention: sports. College sports are a big business, which generate national media attention. The Southeastern Conference had revenues of over $100 million from the marketing of its …

Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi Jan 2004

Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi

LSU Master's Theses

Researchers and clinicians have long treated autism as though it were a disorder that only affected children. As a result, little literature is available on the diagnosis, assessment, and treatment of adults with autism. One of the first issues to address in this population is diagnosis. While several rating scales and diagnostic systems exist for surveying autistic behavior in children, researchers have not demonstrated the reliability of these scales for adults. The present study focused on two commonly used instruments, the Childhood Autism Rating Scale (CARS) and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In the …

Bezier Curves For Metamodeling Of Simulation Output, Harish J. Kingre Jan 2004

Bezier Curves For Metamodeling Of Simulation Output, Harish J. Kingre

LSU Master's Theses

Many design optimization problems rely on simulation models to obtain feasible solutions. Even with substantial improvement in the computational capability of computers, the enormous cost of computation needed for simulation makes it impractical to rely on simulation models. The use of metamodels or surrogate approximations in place of actual simulation models makes analysis realistic by reducing computational burden. There are many popular metamodeling techniques such as Polynomial Regression, Multivariate Adaptive Regression Splines, Radial Basis Functions, Kriging and Artificial Neural Networks. This research proposes a new metamodeling technique that uses Bezier curves and patches. The Bezier curve method is based on …

Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts Jan 2004

Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts

LSU Master's Theses

Northern bobwhite (Colinus virginianus) populations have been declining throughout their range during the past 30 years primarily because of a result of loss of early successional habitat. Specifically, intensive silviculture practices and reduction in the use of prescribed fire has led to this loss. I studied effects of management practices (selective herbicides, mowing, and prescribed fire) on male and covey distribution, and brood-rearing habitats on Jackson-Bienville Wildlife Management Area (JBWMA). Specifically, I used calling surveys to assess landscape characteristics associated bobwhite distribution. I also measured vegetation and arthropod response, using imprinted bobwhite chicks, pitfalls, and sweep nets, to different habitat …

The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt Jan 2004

The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt

LSU Master's Theses

These studies were conducted to elucidate the regional analgesic effect that is observed clinically after treatment of orthopedic disorders with application of extracorporeal shock waves in horses. Regional analgesia after treatment with extracorporeal shock waves presents a concern because it may eliminate protective limiting mechanisms and may place equine athletes with predisposing lesions at risk of sustaining career- or life-ending injuries. Direct percutaneous application of non-focused extracorporeal shock waves to palmar digital nerves in the pastern area of horses resulted in decreased sensory nerve conduction velocities compared with untreated control nerves at 3, 7, and 35 days after treatment. Transmission …

Trajectory And Window Width Predictions For A Cased Hole Sidetrack Using A Whipstock, Harshad Prakash Patil Jan 2004

Trajectory And Window Width Predictions For A Cased Hole Sidetrack Using A Whipstock, Harshad Prakash Patil

LSU Master's Theses

The Trackmaster system manufactured by Smith Services consists of a multi-ramped whipstock and a trimill assembly used to perform a sidetrack from a cased well. Smith Services has observed evidence that the trimill assembly may prematurely leave the face of the whipstock and build excess inclination and dogleg severity or may fall into the original well immediately after leaving the end of the whipstock ramp thus creating a need to predict the borehole trajectory for sidetracking operations. The goal of this project was to predict the borehole trajectory and the window profile cut in the casing by the sidetracking equipment …

Investigation Of Accuracy In Quantitation Of 18f-Fdg Concentration Of Pet/Ct, Yuri Ishihara

LSU Master's Theses

The PET/CT scanner has been recognized as a powerful diagnostic imaging modality in oncology and radiation treatment planning. Traditionally, PET has been used for quantitative analysis, and diagnostic interpretations of PET images greatly relied on a nuclear medicine physician’s experience and knowledge. The PET data set represents a positron emitter’s activity concentration as a gray scale in each pixel. The assurance of the quantitative accuracy of the PET data is critical for diagnosis and staging of disease and evaluation of treatment. The standard uptake value (SUV) is a widely employed parameter in clinical settings to distinguish malignant lesions from others. …

A Meta-Analysis Of Randomness In Human Behavioral Research, Summer Ann Armstrong Jan 2004

A Meta-Analysis Of Randomness In Human Behavioral Research, Summer Ann Armstrong

LSU Master's Theses

This work analyzes the concept of randomness in binary sequences from three different perspectives: mathematically, statistically, and psychologically and examines the research on human perception of randomness and the question of whether or not humans can simulate random behavior. Generally, research shows that human subjects have great difficulty producing random sequences, even when they are instructed and motivated. We survey some of the literature and present some leading theoretical proposals. Finally, we present some basic statistical tests that can be used to evaluate randomness in a given binary sequence.

Migmatization Of Archean Aluminous Metasediments From The Eastern Beartooth Mountains, Montana, U.S.A., Andrew T. Maas Jan 2004

Migmatization Of Archean Aluminous Metasediments From The Eastern Beartooth Mountains, Montana, U.S.A., Andrew T. Maas

LSU Master's Theses

Geothermobarometry, mineral compositions and textures, and thermodynamic models suggest biotite dehydration melting occurred in the peraluminous rocks of the eastern Beartooth Mountains. These Archean metapelitic migmatites are metatexites and diatexites, and have typical metamorphic assemblages of Qtz + Pl + Kfs + Bt + Sil +/- Grt +/- Crd. The subsequent in situ crystallization of the magma derived from the biotite dehydration created migmatitic leucosomes in the rocks. These leucosomes are primarily composed of quartz, plagioclase and potassium feldspar. Water derived from the dehydration of biotite was dissolved in the melted phase. Crystallization of the magma reintroduced this water to …

Evaluation Of New Methods For Processing Drilling Data To Determine The Cause Of Changes In Bit Performance, Jaime Solano Jan 2004

Evaluation Of New Methods For Processing Drilling Data To Determine The Cause Of Changes In Bit Performance, Jaime Solano

LSU Master's Theses

Drilling operations represent the major cost in finding and developing new petroleum reserves. Poor drilling performance when drilling deep shale and strong rocks, as evidenced by slow rate of penetration (ROP), has a significant detrimental impact on drilling costs. Also, it has been concluded that bit balling is the main cause of low ROP when drilling deep, clay-rich shale with water-based mud. In addition, it is estimated that a potential saving in drilling cost of hundreds of millions of dollars a year can be obtained if bit balling is mitigated and ROP is improved. Several methods have been developed in …

Overlap Zones, Growth Faults, And Sedimentation: Using High Resolution Gravity Data, Livingston Parish, La, Carrie Alison Cazes Jan 2004

Overlap Zones, Growth Faults, And Sedimentation: Using High Resolution Gravity Data, Livingston Parish, La, Carrie Alison Cazes

LSU Master's Theses

In south Louisiana, parallel to the coast of the Gulf of Mexico, are belts of east-to-west trending, listric-normal faults with associated contemporaneous sedimentation and fault movement. The Tepetate-Baton Rouge Fault system in south-central Louisiana contains individual fault segments which are arcuate and overlap each other in map view, as seen on LiDAR data. Gravity survey data, with a sample spacing of 20 to 50 m, was collected across normal fault scarps. Structural ramps may form in the area between overlapping normal fault segments creating an east-to-west gradient. This gradient change may divert streams and provide areas for coarse-grained sediments to …

The Impact Of Brief Intervention On Adherence To Medication Regimen Of Low-Income Adults With Type 2 Diabetes, Kathleen E. Kendra Jan 2004

The Impact Of Brief Intervention On Adherence To Medication Regimen Of Low-Income Adults With Type 2 Diabetes, Kathleen E. Kendra

LSU Master's Theses

Patient nonadherence with medication regimen is a common problem facing health care providers treating adult patients with Type 2 diabetes. Poor glycemic control, diabetes related complications, and increased utilization and health care costs are among the outcomes of poor compliance with medical regimen. Prior research indicates moderate success with several techniques to improve medication adherence when used alone. However, the literature suggests a need for an intervention providing a multi-component technique, implementing self-motivating skills and follow-up prompts. Using a 15- minute single exposure intervention, the current study attempted to combine these two procedures (brief intervention including motivational interviewing with follow-up …

An Evaluation Of Multiple Branch Predictor And Trace Cache Advanced Fetch Unit Designs For Dynamically Scheduled Superscalar Processors, Slade S. Maurer Jan 2004

An Evaluation Of Multiple Branch Predictor And Trace Cache Advanced Fetch Unit Designs For Dynamically Scheduled Superscalar Processors, Slade S. Maurer

LSU Master's Theses

Semiconductor feature size continues to decrease permitting superscalar microprocessors to continue to increase the number of functional units available for execution. As the instruction issue width increases beyond the five instruction average basic block size of integer programs, more than one basic block must be issued per cycle to continue to increase instructions per cycle (IPC) performance. Researchers have created methods of fetching instructions beyond the first taken branch to overcome the bottleneck created by the limitations of conventional single branch predictors. We compare the performance of the multiple branch prediction (MBP) and trace cache (TC) fetch unit optimization methods. …

Optimal Test Case Selection For Multi-Component Software System, Praveen Babu Kysetti Jan 2004

Optimal Test Case Selection For Multi-Component Software System, Praveen Babu Kysetti

LSU Master's Theses

The omnipresence of software has forced upon the industry to produce efficient software in a short time. These requirements can be met by code reusability and software testing. Code reusability is achieved by developing software as components/modules rather than a single block. Software coding teams are becoming large to satiate the need of massive requirements. Large teams could work easily if software is developed in a modular fashion. It would be pointless to have software that would crash often. Testing makes the software more reliable. Modularity and reliability is the need of the day. Testing is usually carried out using …

Development Of A Neural Network Approach For The Assessment Of The Performance Of Traffic Sign Retroreflectivity, Nagajyothi Swargam Jan 2004

Development Of A Neural Network Approach For The Assessment Of The Performance Of Traffic Sign Retroreflectivity, Nagajyothi Swargam

LSU Master's Theses

The goal of the research was to develop a new predictive tool for assessing the performance of traffic sign retroreflectivity and to compare the developed tool with the existing linear regression models. Retroreflectivity decreases as sign sheeting ages. Currently Louisiana Department of Transportation and Development (LADOTD) replace signs with low reflectivity based on driver complaints. This practice might have resulted in premature sign replacement (removal of signs with several years of in-service life still remaining) or in non-replacement of signs that are not in compliance with LADOTD minimum reflectivity standards. In this study, both neural network models and regression models …

Black Women Writing Black Mother Figures: Reading Black Motherhood In Their Eyes Were Watching God And Meridian, Alexis Durell Powe Jan 2004

Black Women Writing Black Mother Figures: Reading Black Motherhood In Their Eyes Were Watching God And Meridian, Alexis Durell Powe

LSU Master's Theses

This research explores connections between Zora Neale Hurston's Their Eyes Were Watching God and Alice Walker's Meridian, two important novels in the African American canon rarely studied in conjunction. I examine the novels' portrayals of Black mothers, comparing and contrasting Nanny Crawford and Mrs. Hill as central mother figures. I also examine Leafy Crawford, Meridian Hill, and other minor Black mother/women characters. Though Hurston's and Walker's presentations of Black mothers differ, both authors work toward dismantling traditional stereotypes of Black motherhood, particularly the Black superwoman stereotype, and, thereby, ultimately redefining Black womanhood. In defending this claim, I explore Hurston's …

The Topography Of Syntactic Islands, Danielle Rachel Alfandre Jan 2004

The Topography Of Syntactic Islands, Danielle Rachel Alfandre

LSU Master's Theses

The Adjunct Island Constraint proposed by Ross (1967) together with Chomsky’s Barriers (1986) are not sufficient to account for the ungrammaticality of wh-extraction out of adjunct clauses, nor do they address the instances of grammatical extraction out of such constructions. Extraction out of Adjunct Islands is now completely predictable using a combination of Chomsky’s Minimalist Program (1995) and Kehler’s Coherence Theory (2002). The combination of these two theories gives an account of both the grammatical and ungrammatical instances of wh- extraction out of adjuncts. The principles of the Minimalist Program together with evidence from Old English adverbial clauses determines the …

The Importance Of Fluent Component Skills In Mathematical Comprehension, Chisato Komatsu Jan 2004

The Importance Of Fluent Component Skills In Mathematical Comprehension, Chisato Komatsu

LSU Master's Theses

The primary question to be addressed by the present study was whether fluency on component skills is important in the development of overall competency in mathematics. Reading fluency has served as an excellent predictor of one’s reading comprehension. However, few studies have investigated whether the fluency on component skills is essential in the development of overall competency in mathematics. In fact, there has been a push for instructional strategies to deemphasize the importance component skills. In the current study, 140 students in second- through fourth- grade classrooms from general education participated. Each student took three curriculum-based measurement probes (a single-skill …
