Effect Of Adapted Phonic Faces Story Books On Phonological Skills Of Children With Severe Expressive Language Disorders, Meher Hormazd Banajee

LSU Doctoral Dissertations

Although No Child Left Behind (2001) encourages the inclusion of all children within the regular curriculum, children with severe speech and physical disabilities rarely are provided with the literacy education provided to grade-level peers. This study taught alphabetic skills to three children with severe speech and physical impairments in the context of traditional alphabet books versus Phonic Faces Storybooks. Both storybooks were converted into e-books using Microsoft Office PowerPoint (Microsoft Office, 2003) and accessed using a single rocking lever switch. Two graphemes were selected based on incorrect responses from the pretest administration of the The Phonological Awareness Test (Roberson & …

The Vulnerability To Coaching Across Measures Of Malingering, Adrianne M. Brennan

LSU Doctoral Dissertations

Neuropsychologists are increasingly called upon to conduct evaluations with individuals involved in personal injury litigation. While the inclusion of malingering measures within a test battery may help clinicians determine whether a client has put forth full effort, attorney coaching may allow dishonest clients to circumvent these efforts. The purpose of this study was to determine the degree to which frequently used measures of effort are susceptible to coaching as well as to explore and classify strategies undertaken by coached analogue malingerers. Additionally, potential improvements in the external validity of the simulation design were explored.

Evaluating Precision Agricultural Technologies In A Louisiana Cotton Insect Pest Management System, Joshua Heath Temple

LSU Master's Theses

Twenty-two SVI applications were made to test fields from 2002-2005 using two aircraft …

A Liquid Lens Based On Electrowetting, Jihwan Park

LSU Master's Theses

A primary goal of this work is to develop and characterize a novel liquid lens based on electrowetting. A droplet of silicone oil confined in an aqueous solution works as a lens. Electrowetting then controls the shape of the confined silicone oil, and the focal length may be varied upon an applied electric potential. The planar lens design is employed for easy integration of a lens system into a microfluidic device. The achievements of this work are to develop an electrowetting-based planar liquid lens without an off-the-plane electrode structure and to demonstrate the planar liquid lens with variable focal length …

The Apologia Of Franchino Gafurio: A Critical Edition And Translation, Patrick Joseph Kaufman

LSU Master's Theses

Franchino Gafurio’s Apologia (Turin, 1520) is one musical treatise in a series of works that constituted the famous “pamphlet war” between he and Giovanni Spataro. The dispute originated with the publication of Bartholomeo Ramis de Pareia’s Musica practica (Bologna, 1482). Unconventional and unapologetically critical, Ramis rejected venerated musical traditions in an attempt to align music theory with contemporary music practice. He opposed the Pythagorean division of the monochord and Guidonian solmization syllables, and instead proposed a division which produced pure thirds, and a solmization system based on the octave. His iconoclastic proposals and his highly sarcastic tone called forth a …

The Influence Of Controllability On College Women's Efficacy And Attributions In Physical Activity, Julie Franks Gill

LSU Doctoral Dissertations

There is evidence that individuals’ attributional patterns are important determinants of behavior. Controllability had been identified as an influential dimension of causal attributions. When individuals believe their actions have an effect, or control, on the outcome of an event, they are more likely to engage in a behavior. Contingency of feedback can be used to manipulate perceptions of controllability. The purpose of this study was to investigate the effect of controllability on causal attributions, efficacy, and performance in an exercise setting, using a design that accounts for explanatory styles. It was hypothesized that non-contingent outcomes on an initial task would …

In Defense Of Mandatory Arbitration (If Imposed On The Company), Jean R. Sternlight

Scholarly Works

Having spent much of her academic life battling companies' mandatory imposition of binding arbitration on consumers and employees, the author now switches gears. This Article contemplates whether mandatory binding arbitration is acceptable if imposed by the government on companies (governmental mandatory arbitration) rather than by companies on their employees and consumers (private mandatory arbitration). Specifically, the Article considers the possibility of statutes that would provide little guys (consumers and employees) with an opportunity to take their disputes to binding arbitration rather than litigation. If the little guys chose arbitration over litigation, post-dispute, companies would have to agree to such arbitration, …

Free Women Of Color And Slaveholding In New Orleans, 1810-1830, Anne Ulentin

LSU Master's Theses

Many free women of color lived in antebellum New Orleans. Free women of color tried hard to improve their lives, and engaged in a wide range of economic activities, including slaveholding. Numerous records show that free women of color owned slaves. It is hard to determine why free women of color engaged in such business. Free women of color’s relations with their slaves is controversial as it is difficult to assess why free black women would own slaves, but also buy, sell, and mortgage slaves. Free women of color’s status was exceptional due to specific patterns of manumission in Spanish …

Dna Multiplex Hybridization On Microarrays And Thermodynamic Stability In Solution: A Direct Comparison, Daniel J. Fish, M. Todd Horne, Greg P. Brewood, Jim P. Goodarzi, Saba Alemayehu, Ashwini Bhandiwad, Robert P. Searles, Albert S. Benight

Chemistry Faculty Publications and Presentations

Hybridization intensities of 30 distinct short duplex DNAs measured on spotted microarrays, were directly compared with thermodynamic stabilities measured in solution. DNA sequences were designed to promote formation of perfect match, or hybrid duplexes containing tandem mismatches. Thermodynamic parameters DeltaH degrees , DeltaS degrees and DeltaG degrees of melting transitions in solution were evaluated directly using differential scanning calorimetry. Quantitative comparison with results from 63 multiplex microarray hybridization experiments provided a linear relationship for perfect match and most mismatch duplexes. Examination of outliers suggests that both duplex length and relative position of tandem mismatches could be important factors contributing to …

America's Decision To Drop The Atomic Bomb On Japan, Joseph H. Paulin

LSU Master's Theses

During the time President Truman authorized the use of the atomic bomb against Japan, the United States was preparing to invade the Japanese homeland. The brutality and the suicidal defenses of the Japanese military had shown American planners that there was plenty of fight left in a supposedly defeated enemy. Senior military and civilian leaders presented Truman with several options to force the surrender of Japan. The options included the tightening of the naval blockade and aerial bombardment of Japan, invasion, a negotiated peace settlement, and the atomic bomb became an option, once bomb became operational. Truman received recommendations, advice …

Role Of Heparanase And Heparanase-Degraded Heparan Sulfate In Brain-Metastatic Melanoma, Madhuchhanda Roy

LSU Doctoral Dissertations

Cancer metastasis is a frequent manifestation of malignant melanoma progression. Successful invasion into distant organs by tumor cells must include attachment to microvessel endothelial cells, and degradation of extracellular matrix. Heparan sulfate proteoglycans are ubiquitous macromolecules associated with cell surface and extracellular matrix of a wide range of cells and tissues. Heparanase is an extracellular matrix degradative enzyme which degrades the heparan sulfate chains of heparan sulfate proteoglycans. To investigate effects of changes in heparanase gene expression in metastatic melanoma cells, we constructed adenoviral vectors containing the full-length human heparanase cDNA in both sense (Ad-S/hep) and anti-sense orientations (Ad-AS/hep). We …

A Comparison Of Social Skills Profiles In Intellectually Disabled Adults With And Without Asd, Jonathan Wilkins

LSU Master's Theses

Although there has been a recent increase in research directed toward autism spectrum disorders (ASD), the study of intellectually disabled adults with ASD has gone relatively neglected as efforts have focused largely on young children. Current diagnostic and assessment procedures were created for and validated on this latter group. Many intellectually disabled adults with ASD have not been diagnosed due to the novelty of such instruments and the overlap between symptoms of ASD and severe intellectual disability (ID). A new assessment instrument, the Autism Spectrum Disorders-Diagnostic Scale for Intellectually Disabled Adults (ASD-DA) has been shown to make this fine distinction. …

Alphabetic And Phonemic Awareness In Toddlers, Pamela A. Terrell

LSU Doctoral Dissertations

The ability of 20-24 month-old toddlers to recognize graphemes and phonemes was investigated by reading a Phonic Faces (PF) alphabet picture book. Phonic Faces iconically picture a letter in the mouth of a character producing the sound (the curve of the P looks like the top lip popping the /p/ sound). The book was composed of nine letters and was read individually to experimental subjects three times weekly for six weeks. The control group received no treatment, but engaged in individual play activities for comparable time. Following six-weeks the groups alternated so the former control group now received the alphabet …

Transcendental Eigenvalue Problems Associated With Vibration, Buckling And Control, Jayaram Subramanian

LSU Master's Theses

The static and dynamic analysis of structures requires us to obtain solutions of their espective governing differential equations subject to appropriate boundary conditions. The dynamic analysis of non-uniform continuous structures is of primary interest, as most traditional methods take the help of discrete models to analyze them. Well established discrete model methods lead to an algebraic eigenvalue problem, the characteristic equation associated with which is a polynomial. The spectral characteristics of a continuous system nevertheless are represented by transcendental functions and cannot be approximated by polynomials efficiently. Hence finite dimensional discrete models are not capable of predicting the response of …

Predictive Data Compression Using Adaptive Arithmetic Coding, Claudio Jose Iombo

LSU Master's Theses

The commonly used data compression techniques do not necessarily provide maximal compression and neither do they define the most efficient framework for transmission of data. In this thesis we investigate variants of the standard compression algorithms that use the strategy of partitioning of the data to be compressed. Doing so not only increases the compression ratio in many instances, it also reduces the maximum data block size for transmission. The partitioning of the data is made using a Markov model to predict if doing so would result in increased compression ratio. Experiments have been performed on text files comparing the …
