Integration Of Paleotempestology With Coastal Risk And Vulnerability Assessment: Case Studies From The Dominican Republic And Nicaragua, Devyani Kar

LSU Doctoral Dissertations

Hurricanes account for a significant portion of damages, injuries, and fatalities in the Caribbean. The Dominican Republic has had 3 major hurricane strikes in this century resulting in loss of lives for thousands of people and billions of US $ in economic loss. Major hurricanes had been relatively infrequent in north-eastern Nicaragua’s modern history until Hurricane Felix, a Category 5 storm, made landfall in the north-east in 2007. It caused 130 confirmed deaths and brought devastation to many villages. These events highlight a need for re-evaluation of hurricane risk based on a more comprehensive and long-term hurricane history. Using paleotempestological …

The Relationship Between Social Skills And Challenging Behaviors In Children With Autism Spectrum Disorders, Jonathan Wilkins

LSU Doctoral Dissertations

The autism spectrum disorders (ASD) are among the most serious and debilitating conditions with onset in early childhood. Deficits in social interaction skills are considered to be the hallmark set of symptoms and are given the most weight in current diagnostic systems. Although not considered among the core symptoms of ASD, challenging behaviors in the form of physical aggression, property destruction, and self-injury also commonly occur. Challenging behaviors of this nature are a salient feature of ASD because of their potential to cause harm to self and others as well as limit a child’s access to opportunities in community and …

The Effect Of Directed Attention Score Study Procedures On Music Majors' Error Detection In Three-Part Instrumental Music, Amanda Lynn Schlegel

LSU Doctoral Dissertations

The purpose of this study was to determine the effects of directing participant (N = 60) attention to one voice in three-part homophonic and polyphonic instrumental music on music majors’ detection of pitch and rhythm errors. Directed attention participants studied one voice prior to studying the entire score through either visual or aural methods. Visual group participants (n = 20) studied the voice of directed attention (VDA), which was color highlighted, in silence. Aural group participants (n = 20) studied the VDA in a three-phase treatment: sight-singing the VDA, using a piano and their own singing to correct any errors …

Improving Software Quality Using An Ontology-Based Approach, Yixin Luo

LSU Doctoral Dissertations

Ensuring quality in software development is a challenging process. The concepts of anti-pattern and bad code smells utilize the knowledge of reoccurring problems to improve the quality of current and future software development. Anti-patterns describe recurring bad design solutions while bad code smells describe source code that is error-free but difficult to understand and maintain. Code refactoring aims to remove bad code smells without changing a program’s functionality while improving program quality. There are metrics-based tools to detect a few bad code smells from source code; however, the knowledge and understanding of these indicators of low quality software are still …

The Effect Of A Planned Instructional Program On The Empathy Levels Of Registered Nurses At A Metropolitan Hospital In Southern Louisiana, Deborah K. Charnley

Dynamic Acromiohumeral Interval Changes During Scapular Plane Arm Motions, Melissa Deen Thompson

LSU Doctoral Dissertations

This purpose of this dissertation is to explore changes in the acromiohumeral interval during dynamic motion in the scapular plane. All of the experiments were completed in the Football Operations Athletic Training Room at Louisiana State University. The first experiment which investigated dynamic acromiohumeral interval changes in baseball players during a loaded and unloaded scaption exercise from 0°-75°, has been accepted for publication by the Journal of Shoulder and Elbow Surgery (in press, 2010). The mean acromiohumeral interval (AHI) for unloaded and loaded scaption decreased significantly (p<.001) from the arm at the side until 45° and loaded scaption narrowed AHI at 60° (p=.005) and 75° (p=.003). The second experiment investigates AHI and scapular upward rotation (SUR) changes in baseball and softball players during scaption exercises from 0°-75°. Significant load related narrowing of the AHI at 45°(p=.005), 60°(p=.001), and 75°(p<.001) and a significant load-position interaction (p=.001) at 0° and 75°was observed for all subjects. No gender differences in SUR or AHI were found. AHI and SUR displayed moderate positive correlations at 30° for both the unloaded scaption (r=.648, p=.001) and the loaded scaption (r=.445, p=.038) however, no significant relationships were present at 0°, 45°, 60° or 75°. The third experiment compared dynamic acromiohumeral interval and scapulohumeral rhythm changes in trained and untrained females during scaption exercises from 0°-90°. In general, AHI was maximal with the arm at the side and declined significantly (p<.001) during arm elevation until 60°, but increased significantly (p<.001) between 60° and 90°. Significant load related narrowing of the AHI at all positions (p<.05), a more negative SUR at 0° (p<.001) and a more positive SUR at 90° (p=.009) was observed for all subjects. Female athletes had significantly stronger external rotators (p<.001), larger overall AHI (p=.003) and more SUR (p=.008) than untrained females. Significant positive correlations (p<.05) between AHI and SUR were observed at 0°, 30°, and 60° during both loaded and unloaded scaption.

Relationship Between Dissimilar Cognitive Styles, Use Of Coping Behavior And Use Of Learning Strategies, Chevanese Latoya Samms

LSU Doctoral Dissertations

Research on teacher learning styles and teaching styles have explained that teachers inadvertently mirror their own styles as they teach (Sternberg, 1994; Zhang, 2002) and as such apply teaching strategies that fit personal preference. With this one-style-fits-all approach, students’ individual differences are often ignored and teaching methods are rarely varied to accommodate (McKeachie, 1995) the student. This relationship between one’s preferred style and his or her teaching style may also influence student learning (Zhang, 2001) based on findings which pointed out that students who had similar styles like those of their instructors were more comfortable with the techniques the instructor …

"Do It For Me, My Dear": Structuration And Relational Dialectics Among Mother-Daughter Dyads In Lebanese Arranged Marriages, Khaled Nasser

LSU Doctoral Dissertations

This research applied a two-step triangulation approach to the study of mother-daughter communication in arranged marriages among the religious Sunnis of Beirut, Lebanon. Combining the theory of structuration and relational dialectics in one theoretical framework, the study investigated the role of mother-daughter interactions in the socialization of the daughter into the marital experience. The study investigated the process of marital socialization by first surveying 199 mother-daughter dyads, representing 398 individuals. In the second step, in-depth interviews were conducted with 12 families (three interviews per dyad), randomly selected out of the 199 surveyed pairs. The dyadic data analysis of the surveys …

The Evolution Of Freeze Tolerance In A Historically Tropical Snail, Alice B. Dennis

LSU Doctoral Dissertations

Geographic range differences among species may result from differences in their physiological tolerances. In the intertidal zone, marine and terrestrial environments intersect to create a unique habitat, across which physiological tolerance strongly influences range. The snail Melampus bidentatus occurs in coastal salt marshes in the western Atlantic and Gulf of Mexico. I have used sequence data from one mitochondrial (CO1) and two nuclear markers (histone H3 and a mitochondrial carrier protein, MCP) to identify three cryptic species within Melampus bidentatus, and to infer their relationships to other Melampus. To identify microhabitat differences between two cryptic species, I modeled their distributions …

Quantum Light For Quantum Technologies, William Nicholas Plick

LSU Doctoral Dissertations

In this thesis we will theoretically investigate three potentially useful physical systems, after first developing the theoretical framework necessary for studying them. First, we will study the multiphoton absorption properties of maximally path entangled number (N00N) states. This is directly relevant to quantum lithography, and beating the Rayleigh diffraction limit. Next, we will develop a new scheme for quantum interferometry: dubbed coherent-light boosted super-sensitive quantum interferometry, which has the potential to reach below the shot noise limit for high photon fluxes, and requires no esoteric detection protocol, or technological elements that have yet to be developed. Finally we propose a …

Target Eccentricity Effects For Defensive Responses, Taegyong Kwon

LSU Doctoral Dissertations

Defensive actions involving goal-directed responses to visual stimuli presented in different parts of the viewing field commonly include movements either toward (TOWARD) or away from (AWAY) the actual stimulus. One can categorize the type of defensive movements by outcome or the level of stimulus-response (S-R) compatibility, where a congruent response corresponds to a response in the TOWARD condition and an incongruent response corresponds to a response in the AWAY condition. In an effort to better understand defensive responses, which have received less attention in the literature than offensive movements regardless of their importance in combative situations, we studied the responses …

Computer Simulation Of Ion-Induced Nucleation In The Presence Of Single Ions And Ion Pairs, Samuel Keasler

LSU Doctoral Dissertations

Atmospheric aerosol particles play an important role in climate and human health. Despite their importance, the mechanisms of their formation are still poorly understood. Ion-induced nucleation may play a role in the process, but details are lacking about how the nucleation rate depends on the size, charge, and number of ions in the cluster. In order to better understand the role that ions might play in new particle formation, we have performed a series of AVUS-HR simulations of the water nucleation in the presence of both single ions and ion pairs. These simulations have shown that the location of the …

A Study Of The Interactions Of Lipid Bilayers And Dendrimers Using Small Angle X-Ray Scattering And Freeze Fracture Transmission Electron Microscopy, Derek R. Dorman

LSU Doctoral Dissertations

Lipids are fundamental to all life forms, a key component of cell walls, and essential to proper respiratory function. They are amphiphilic molecules and readily form bilayers. Dendrimers are designer molecules that can be tailored to provide a variety of endgroup moieties, sizes, and charges. The interaction of liposomes and dendrimers can provide information on how medicine interacts with cells and an array of unique structures can be imagined from their assembly into superstructures. Polypropylenimine tetraamine (DAB-Am) and 1-directional arborol dendrimers have been studied in different molar concentrations with 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) bilayers. One-directional arborols are amphiphilic dendrimers with a hydrophilic …

Crossroads And Signposts: The Ada Amendments Act Of 2008, Jeannette Cox

School of Law Faculty Publications

Although the apparent purpose of the 2008 amendments to the Americans with Disabilities Act (ADA) is solely to broaden the ADA 's protected class, the manner in which the amendments achieve this purpose erodes the statute's explicit textual support for understanding persons with disabilities as a politically subordinated minority. The amendments also strengthen the statutory link between the biological severity of a person's disability and that person's right to sue for ADA accommodations. Accordingly, for some courts, the amendments will reinforce the perception that the ADA differs from traditional civil rights law.

Federal courts' understanding of the ADA 's relationship …

The Auxiliary System Of Typically Developing Children Acquiring African American English, Brandi Lynette Newkirk

LSU Doctoral Dissertations

This study’s purpose was to examine the acquisition and use of BE, DO, and modal auxiliaries by African American English (AAE)-speaking children. The impetus for this work was the lack of information regarding the developmental trajectory of these auxiliary types and their use, in AAE relative to what is known about auxiliary acquisition and use in Mainstream American English (MAE). The study used two datasets of language samples: one that contained 48 language samples from 3 ½-year-old children and one that contained 36 longitudinal language samples of five children who were between 18 and 51 months of age.

Paths Of Most Resistance: Navigating The Culture Industry In William Faulkner, Richard Wright, Delmore Schwartz, And Eudora Welty, Jason Dupuy

LSU Doctoral Dissertations

This dissertation explores how four modernist writers of the 1930s and 1940s—William Faulkner, Richard Wright, Delmore Schwartz, and Eudora Welty—used their works to present ways to resist and navigate what they present as the frequently reductive worldview offered by the culture industry. Faulkner tends to show the culture industry as selling easy answers that focus on the end result, which allows his characters to approach the culture industry with a sense of fatalism. To resist this, Faulkner stresses a step-by-step, complex dialectical understanding of the culture industry, one that shows the fissures in its seemingly straightforward narratives and allows the …

The purpose of Study 1 was to develop a reliable and valid scale of social shopping for fashion. With the scale, Study 2 aimed to develop and test a structural model of social shopping process. In Study 1, a three-step procedure for scale development was followed: item generation, scale purification, and scale validation. As a result, a five-dimensional scale, along with sixteen behavioral items, was developed representing distinctive dimension of social shopping for …

In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon

LSU Doctoral Dissertations

Brucellosis, a zoonotic disease caused by Brucella spp., presents both health and economic difficulties for livestock, wildlife, and humans. While brucellosis is nearly eradicated in the United States, the disease remains detrimental in many countries worldwide. Attempts to produce a safe and effective small ruminant vaccine have been met with limited success. The current vaccine for bovine brucellosis in the United States is B. abortus RB51. This strain transiently colonizes the host and induces a cell-mediated immune response. Levels of protection have not been demonstrated in goats and thus it is considered a relatively poor caprine vaccine that probably does …

"Teach Us Incessantly": Lessons And Learning In The Antebellum Gulf South, Sarah L. Hyde

LSU Doctoral Dissertations

Before 1860 people in the Gulf South valued education and sought to extend schooling to residents across the region. Southerners learned in a variety of different settings – within their own homes taught by a family member or hired tutor, at private or parochial schools as well as in public free schools. Regardless of the venue, the ubiquity of learning in the region reveals the importance of education in Southern culture. In the 1820s and 1830s, legislators in Louisiana, Mississippi, and Alabama sought to increase access to education by offering financial assistance to private schools in order to offset tuition …

In 1913 it moved to Lafayette, Louisiana, and in 1947 began admitting males as well as women. It closed in 1993. Through much of its history, this secondary school was staffed primarily by the Sisters of the Holy Family, the second oldest order of African American nuns in the United States, and the Divine Word Missionaries, one of the earliest groups of Catholic priests to accept African American candidates for the priesthood. In 1992, Gerard …

Retrotransposon-Mediated Genomic Dynamism, Thomas Joshua Meyer

LSU Doctoral Dissertations

Retrotransposons, a class of mobile elements, generate new copies in host genomes using RNA intermediates and reverse transcribing new copies into new loci. As such, the copy numbers of many active retrotransposon families increase dramatically over time. For example, ~42% of the human genome is comprised of retrotransposon sequences. The insertion activity of these elements, and the high degree of identity existing between the copies, have been shown to significantly impact the structure and stability of genomes, contributing in various ways from exon shuffling to inversions and from non-allelic homologous recombination to altering gene regulation. The two most successful mobile …
