The Sociomoral Atmosphere Rating Template (Smart): An Investigation Of Reliability And Validity, Richard Sean Durham Jan 2007

The Sociomoral Atmosphere Rating Template (Smart): An Investigation Of Reliability And Validity, Richard Sean Durham

LSU Doctoral Dissertations

This study describes the development of the Sociomoral Atmosphere Rating Template (SMART), an instrument designed to rate the sociomoral atmosphere in early childhood classrooms, and an investigation of the instrument's reliability and validity. Results indicate that individuals can be trained to reliably use the SMART and that the measure is internally consistent. In addition to its face validity, results indicate that the SMART has convergent validity when compared to the Early Childhood Environmental Rating Scale - Revised (Harms, Clifford, & Cryer, 1998) and the Teacher Interaction Scale (Arnett, 1989). Comparisons at the subscale level suggest discriminant validity. Implications and plans …

An Architecture For Embedded System Communication, Chakradhar Medavarapu Jan 2007

An Architecture For Embedded System Communication, Chakradhar Medavarapu

LSU Master's Theses

Time is a major constraint in the development of most embedded systems. In many cases, the development of embedded software is directly dependent on the development of the embedded systems. This calls for a development framework that enables embedded software and hardware to be developed in parallel. In an attempt to solve the problem, a concept prototype hardware-in-the-loop (HIL) simulation methodology has been proposed and implemented at the Ohio State University for the TMS320LF2407A DSP board. We build on top of that HIL system by rewriting the low level device drivers that allow data and control information to be set …

Evaluation Of Compliance With The Long Term 1 Enhanced Surface Water Treatment Rule, Racquel Rena Douglas

LSU Master's Theses

Cryptosporidium is a common protozoan parasite that causes cryptosporidiosis, a severe gastrointestinal disease. Currently, there is no antibiotic available to treat the disease. Cryptosporidium has been responsible for several waterborne disease outbreaks in the United States. The largest cryptosporidiosis outbreak in United States history occurred in Milwaukee, Wisconsin in spring 1993. The vulnerability of the United State drinking water supply to waterborne disease outbreak is still prevalent nearly 15 years after the Milwaukee outbreak. In order to effectively control Cryptosporidium, the EPA has strengthened the regulations on turbidity control for filtration performance by implementing the Long Term 1 Enhanced Surface …

Relationships Between Macroinvertebrate Communities And Environmental Characteristics Of Headwater Streams In Central Louisiana, Adrienne Viosca Jan 2007

Relationships Between Macroinvertebrate Communities And Environmental Characteristics Of Headwater Streams In Central Louisiana, Adrienne Viosca

LSU Master's Theses

Headwater streams are an integral part of any watershed system because they strongly influence the physical, chemical, and biological components of downstream reaches. Little information exists about macroinvertebrate community structure, spatiotemporal variation, or their relationships with environmental factors in low-gradient headwater streams of the subtropical coastal plain region in the Southern US. These headwater streams are typically slow moving, capable of accumulating large amounts of organic material, and often become intermittent during the dry season. Research is needed to understand the effects of these unique characteristics on stream health and ecology. This study aimed to determine aquatic macroinvertebrate community structure, …

Unwelcome Neighbors? Industrial Growth And Water Pollution In Lake Charles, Louisiana, 1940-1960, Jonathan Zachary Delaune Jan 2007

Unwelcome Neighbors? Industrial Growth And Water Pollution In Lake Charles, Louisiana, 1940-1960, Jonathan Zachary Delaune

LSU Master's Theses

This paper focuses on the industrialization of Lake Charles, Louisiana during World War Two and the resulting shifts in pollution-related policy and public perceptions of pollution. A major impetus for the industrialization of the South was federal investment during the war. This is especially true for Lake Charles, a city where industrial agglomeration began with war-time financing of manufacturing plants to combat the shortages of aviation fuel and rubber. By tracing the public response to offensive pollution and the resulting shift in public policy, this paper will reveal a fundamental conflict between development-minded government institutions and a population interested in …

Behavior Problems Exhibited In Institutionalized Persons With Intellectual Disabilities And Schizophrenia Spectrum Disorders, Ryan Thorson Jan 2007

Behavior Problems Exhibited In Institutionalized Persons With Intellectual Disabilities And Schizophrenia Spectrum Disorders, Ryan Thorson

LSU Master's Theses

Although our understanding of dual diagnosis has improved in recent years, a deficit exists in our knowledge of how schizophrenia spectrum disorders (SSD) manifest themselves in individuals with intellectual disabilities (ID). We also know very little about the behavioral problems present with the ID population based on the existence of psychopathology. The present research attempted to extend the literature by comparing behavior problems of individuals with intellectual disability with SSD, any form of psychopathology, and no psychopathology. Utilizing the Behavior Problems Inventory (BPI), three areas of problem behaviors were examined (self-injurious behavior, stereotypic behavior, and aggressive/destructive behavior) and a total …

Parenting Experiences Of Eastern European Immigrant Professionals In The U.S.: A Qualitative Study, Olena Nesteruk

LSU Doctoral Dissertations

In 2004, the nation’s foreign-born population numbered approximately 35 million comprising about 12% of the total U.S. population (U.S. Census Bureau, 2005). Most studies of immigrants primarily research the two largest immigrant groups, those from Latin America and Asia, while little has been done with the less visible population of immigrants from Eastern Europe. Also, we know much about the experiences of low-income immigrants of color, but little about the experiences of white immigrant families in the professional ranks. A qualitative study was conducted with immigrant professionals from Eastern Europe to explore their experiences with raising children in a new …

Using Power Spectra To Look For Anisotropies In Ultra-High Energy Cosmic Ray Distributions, Megan Alicia Mcewen Jan 2007

Using Power Spectra To Look For Anisotropies In Ultra-High Energy Cosmic Ray Distributions, Megan Alicia Mcewen

LSU Doctoral Dissertations

The origins and compositions of ultra-high energy cosmic rays (UHECR) remains a mystery to this day. The Pierre Auger Observatory (PAO) is being constructed now in the hopes that it will help solve this mystery by detecting more UHECR than any previous experiment. In this dissertation, I will discuss this experiment, and analyze the data collected so far by comparing it with simulated data from possible source distributions. In these simulations, I will track antiprotons, along with other possible cosmic ray primaries, through various models of galactic and extragalactic magnetic fields. Once they reach a certain distance, I will record …

Georges De La Tour's Flea-Catcher And The Iconography Of The Flea-Hunt In Seventeenth-Century Baroque Art, Crissy Bergeron Jan 2007

Georges De La Tour's Flea-Catcher And The Iconography Of The Flea-Hunt In Seventeenth-Century Baroque Art, Crissy Bergeron

LSU Master's Theses

This essay performs a comprehensive investigation of the thematic possibilities for Georges de La Tour's Flea-Catcher (1630s-1640s) based on related artworks, religion, and emblematic, literary, and pseudo-scientific texts that may have had a bearing on it. The results of my research are grouped into two categories that embrace the range of interpretations for the work: religion and sexuality. While religious iconography characterizes most of La Tour's extant creations, the hypothetically religious content of his Flea-Catcher is difficult to discern. However, it is possible to analyze the iconography, as well as some of the ancillary motifs found in La Tour's painting, …

Building A Better Mousetrap, Jonathan Pellitteri Jan 2007

Building A Better Mousetrap, Jonathan Pellitteri

LSU Master's Theses

ABSTRACT To me the phrase “building a better mousetrap” implies that a needless change has been made to something that already sufficiently serves its purpose. These words identify my thoughts about how over the past three years I have begun to replace trusted means of communication with newer technologies. My thesis work examines my relationship to these new modes of communication and how, as I see others around me making them useful parts of their lives, I am continually snared by the promise of their convenience. Ultimately, however, they distract and frustrate me with the countless hours I allow them …

Phylogenetic Systematics, Biogeography, And Evolutionary Ecology Of The True Crocodiles (Eusuchia: Crocodylidae: Crocodylus), Jamie Richard Oaks

LSU Master's Theses

Modern crocodylian systematics has been dominated by investigations of higher-level relationships aimed at resolving the disparity between morphological and molecular data, especially regarding the true gharial (Gavialis). Consequently, no studies to date have provided adequate resolution of the interspecific relationships within the most broadly distributed, ecologically diverse, and species-rich crocodylian genus, Crocodylus. In this study, Bayesian and ML partitioned phylogenetic analyses were performed on a DNA sequence dataset of 7,282 base pairs representing four mitochondrial regions, nine nuclear loci, and all 23 crocodylian species. The analyses were performed on a suite of partitioning strategies to investigate the modeling effects of …

An Exploration Of The Impact Of Picture Book Illustrations On The Comprehension Skills And Vocabulary Development Of Emergent Readers, Judy Lavender Nicholas

LSU Doctoral Dissertations

The formal instruction process of teaching reading to emergent and beginning readers needs to incorporate a much more multimodal approach. People today, not only in America but in many other countries as well, are more graphically oriented than any other generation has ever been. Children in our society expect to experience pictures and images in almost everything they encounter. This graphic orientation needs to be taken advantage of and incorporated into the educational process in ways that can be beneficial to the learning environments of children in our schools. Reading programs need to forego one-dimensional teaching methods and learn how …

An Investigation Of Maternal Psychopathology As A Moderator Of Child Response Following Hurricane Katrina, Ann Wingate Spell Jan 2007

An Investigation Of Maternal Psychopathology As A Moderator Of Child Response Following Hurricane Katrina, Ann Wingate Spell

LSU Doctoral Dissertations

Previous disaster research has focused on possible risk factors that contribute to child psychological distress following disaster exposure. One of these factors, parental psychopathology, has consistently been indicated as associated with and predictive of child functioning post-disaster. In related areas of violence exposure, researchers have gone beyond correlation and prediction in their attempt to elucidate the relationship between parental psychopathology and child functioning post-trauma. Such researchers have investigated and confirmed parental psychopathology as a moderator variable in the relationship between child violence exposure and child functioning. Thus, in considering the status of research regarding risk factors of child functioning post-disaster …

Narratives In Music: Schelmo, Hebraic Rhapsody For Cello And Orchestra, Asu Perihan Karadut

LSU Doctoral Dissertations

Born in July 1880, in Geneva, Switzerland, Ernest Bloch became one of the leading composers of the 20th century. He wrote series of works, which he called “The Jewish Cycle.” They represented a new, distinctive musical language, in which Bloch combined eastern and western music traits. Schelomo, Hebraic Rhapsody for Cello and Orchestra (1915-16) was the last composition from the cycle. It showed mastery of a style Bloch had been developing since his earlier compositions. This project will show Schelomo’s place in “The Jewish Cycle” and its importance on Bloch’s departure from the popular trends of the early 20th century. …

Local Norms And Innovations Within The System Of Locative Prepositions In Cajun French, Sibylle Maria Noetzel Jan 2007

Local Norms And Innovations Within The System Of Locative Prepositions In Cajun French, Sibylle Maria Noetzel

LSU Doctoral Dissertations

Cajun French presents variable use of linguistic features, as any other variety of French does. Many Cajun French features are considered as deviant from the French norm or triggered by attrition although fluent speakers of Cajun French have always used them. In this sociolinguistic study, we analyze the use of locative prepositions. We add two important dimensions to existing studies: real-time evidence for a diachronic descriptive perspective, and a methodological tool, measuring the degree of exposure to French (MDI). This approach allows us to establish the local prepositional norm of Cajun French and phenomena due to attrition. Large amounts of …
