Debussy And The Fragment., Linda Page Cummins
Debussy And The Fragment., Linda Page Cummins
LSU Historical Dissertations and Theses
The dissertation identifies and studies fragmentary structures---structures that give the impression of incompletion or interruption---in the music of Claude Debussy. Although fragments---which play a decisive role in nineteenth- and twentieth-century aethetics---have been discussed extensively in literature and the visual arts, relatively little critical attention was paid to them by musicologists until Daverio and Rosen, in the 1990s, investigated the romantic musical fragment. The dissertation traces the history of the literary fragment from the late middle ages through the nineteenth century. With this history as background, it places Debussy's fragmentary musical structures in relation to those of composers like Schumann and …
Pathobiology Of Streptococcus Iniae Infections In Cultured Tilapia., Alvin Cyril Camus
Pathobiology Of Streptococcus Iniae Infections In Cultured Tilapia., Alvin Cyril Camus
LSU Historical Dissertations and Theses
Streptococcus iniae was first isolated in 1972 from an Amazon River dolphin. It reappeared as a fish pathogen in Japan several years later. Since then it has steadily increased in incidence and host range worldwide, and is a known zoonotic agent. In the United States it is the most significant pathogen affecting growth of tilapia aquaculture. Histopathologic descriptions are incomplete and little is known concerning pathogenesis of the disease or virulence mechanisms of the organism. A composite of lesions was compiled from diseased tilapia evaluated by the Aquatic Animal Disease Diagnostic Laboratory, Louisiana State University from 1995--2001. In common with …
A Study Of The Measurement And Sources Of Teachers' Self And Collective Efficacy Beliefs In Professional Learning Environments., Amy Marie Barrilleaux Dellinger
A Study Of The Measurement And Sources Of Teachers' Self And Collective Efficacy Beliefs In Professional Learning Environments., Amy Marie Barrilleaux Dellinger
LSU Historical Dissertations and Theses
This study examined relationships between sources of efficacy information available in teachers' professional learning environments and teacher self-, work-group collective and faculty collective efficacy beliefs. An argument is presented that teachers' individual and collective efficacy beliefs are vital factors that mediate linkages between professional learning and meaningful change in schools. School professional learning environments are hypothesized to provide efficacy information that may serve to enhance teachers' beliefs in their abilities to accomplish tasks that are linked to effective teaching and learning. Social cognitive theory and triadic reciprocal causation provided the framework for this research. Self-efficacy theory, a sub-theory of social …

Plant Uptake Of Desorption Resistant Organic Chemicals From Sediments., Cesar Miguel Gomez Hermosillo
LSU Historical Dissertations and Theses
Two types of wetland plants, a woody species, black willow ( Salix nigra), and a non-woody, the macrophyte three-square bulrush (Scirpus olneyi), were used in laboratory studies to evaluate relationships between sorption, plant uptake, translocation and transpiration of phenanthrene, a model polycyclic aromatic hydrocarbon and chlorobenzene, a model chlorinated benzene from the reversible and desorption-resistant compartment of a sediment for Phenanthrene (PHEN) and a wetland soil for chlorobenzene (CB). The wetland soil is from The Petro Processors Inc. site (PPI), a 77-acre CERCLA facility located about 10 miles north of Baton Rouge, Louisiana. Other studies have evaluated the plant uptake …
The Development Of An Instrument To Assess Strategical Information Processing Style., Beverly Allain Farrell
The Development Of An Instrument To Assess Strategical Information Processing Style., Beverly Allain Farrell
LSU Historical Dissertations and Theses
Underpinned on the theories of individual differences and the information processing paradigm, the author hypothesized that there were five different strategical information processing styles (SIPS) that individuals prefer to use when processing information. The five constructs are visuo-spatial, analytical, social, categorical, and verbal. Based on this hypothesis, the researcher developed a self-assessment instrument containing specific measurable descriptors for each of the five hypothesized constructs. However, in this study the empirical evidence verified only four strategical information processing styles: visuo-spatial, analytical, social, and categorical. Although the verbal style is theoretically appealing, it did not prove to be a valid construct in …

Atomic And Electronic Structure Of Ultra-Thin Metal Epitaxy On Metal And Semiconductor Surfaces., Dustin Alexander Hite
Atomic And Electronic Structure Of Ultra-Thin Metal Epitaxy On Metal And Semiconductor Surfaces., Dustin Alexander Hite
LSU Historical Dissertations and Theses
The fundamental study of heteroepitaxy has proved to have profound influences on technological applications of thin films, particularly due to the reduced dimensionality and quantum mechanical effects found in these unique nanostructured systems. In this study, particular attention is given to the correlations between atomic-scale morphology and the consequential electronic structure of heteroepitaxial systems that exhibit deviations from traditional growth modes in the initial stages of growth. Surface-confined systems are especially interesting because they exhibit properties that are fundamentally different from the bulk and often have no bulk analogs existing in nature. The surface-sensitive techniques of variable-temperature scanning tunneling microscopy …
Robust Control Of Uncertain Time -Delay Systems., Yun-Ping Huang
Robust Control Of Uncertain Time -Delay Systems., Yun-Ping Huang
LSU Historical Dissertations and Theses
Time-delay systems are common in industries. Direct analysis and synthesis of control systems with time delays are complicated and approximation methods such as Pade approximation are usually applied. However, the issues of control system robustness with respect to model uncertainties and approximation errors have not been sufficiently addressed. This dissertation focus on robustness of time-delay systems, especially robustness with respect to time delays, which has been discussed extensively using Lyapunov second method. We propose two methods in this dissertation to reformulate the problems into standard mu or Hinfinity problems. The first method involves representing the systems in linear functional transformation …

Testing Theories Of Government Growth In The Fifty States, 1945 To 1998., Branwell Dubose Ravenel Kapeluck
Testing Theories Of Government Growth In The Fifty States, 1945 To 1998., Branwell Dubose Ravenel Kapeluck
LSU Historical Dissertations and Theses
This dissertation explores the determinants of government growth in the American states. Understanding the causes of public sector growth is important as the administration of government programs is increasingly devolved to the states. Past research has typically been on national-level growth. However, the variety in state institutional structures, resource bases, and population needs makes for an ideal "comparative laboratory." With some exceptions, state-level studies have had a public finance approach that often exclude relevant political and demographic factors that can lead to increased public sector size. My analysis of state government growth tests thirteen models covering both traditional political explanations …
Obstacles In Recruiting African Americans For Clinical Trials., Betty Monroe Kennedy
Obstacles In Recruiting African Americans For Clinical Trials., Betty Monroe Kennedy
LSU Historical Dissertations and Theses
Previous abusive clinical trials have caused several obstacles in recruiting African Americans for clinical trials today. The memory of the Tuskegee Syphilis Study alone remains a hard pill to swallow and is a constant hindrance to recruiting potential African Americans specifically males, for clinical trials. The basic trust that African Americans have for physician researchers, U.S. government doctors, U.S. government-sponsored research, and biomedical research in general has been seriously, although not irrevocably, breached. The purpose of this study was to gain an understanding of the knowledge, attitudes, and beliefs African Americans have that support decisions to either participate or not …

Wavelet Analysis And Classification Of Urban Environment Using High -Resolution Multispectral Image Data., Soe Win Myint
Wavelet Analysis And Classification Of Urban Environment Using High -Resolution Multispectral Image Data., Soe Win Myint
LSU Historical Dissertations and Theses
Attempts to analyze urban features and classify land use and land cover directly from high-resolution satellite data with traditional computer classification techniques have proven to be inefficient. The fundamental problem usually found in identifying urban land cover types from high-resolution satellite imagery is that urban areas are composed of diverse materials (metal, glass, concrete, asphalt, plastic, trees, soil, etc.). These materials, each of which may have completely different spectral characteristics, are combined in complex ways by human beings. Hence, each urban land cover type may contain several different objects with different reflectance values. Noisy appearance with lots of edges, and …

Sources And Types Of Formal And Informal Assistance: Patterns Among Louisiana's Welfare Population., Alison Kay Neustrom
LSU Historical Dissertations and Theses
My purpose in this dissertation is to examine the extent to which recipients report social capital in the form of social support and what I call informal assistance. I define informal assistance as those assets that assist in the daily lives of welfare recipients. This dissertation examines the role of residence, human capital, family of origin, and current household structure on informal assistance. I also compare the forms of assistance and instrumental resources of non-metropolitan and metropolitan welfare recipients to determine whether geographic context mediates the use of informal assistance. Data for this study were from the Louisiana State University …

Pyrrole -Terminated Dendrimers For Use In Polymerizable Monolayers And Guest Encapsulation Systems., Charles Oakley Noble Iv
LSU Historical Dissertations and Theses
This work demonstrates the use of pyrrole-terminated dendrimers (PTD)s for the oxidation-state-dependant encapsulation and release of various guest molecules. In order to achieve the goals of this research, a two-step approach was taken. The first portion of this doctoral work involved synthesis of low-generation (small number of peripheral groups) PTDs having a simple structure (DAB-Py x, X = 4, 8, 16) and studying the intramolecular oligomerization of the terminal pyrrole groups by well-known electrochemical methods. After the proof-of-concept study with low-generation PTDs, the next step involving more complex, high-generation PTDs (DAB(COCyPy)x, Y = 3 or 5, X = 32 or …
The Anxious *Double: Twins In Plays Of The 1970s, 1980s, And 1990s., Shellie Kaye O'Neal
The Anxious *Double: Twins In Plays Of The 1970s, 1980s, And 1990s., Shellie Kaye O'Neal
LSU Historical Dissertations and Theses
Twin characters have consistently appeared in dramatic literature throughout history. Playwrights from Shakespeare to Goldoni have employed twins in works which usually rely upon the device of mistaken identity. However, twin characters who have appeared in plays of the last thirty years have been employed with more weighty intentions. This dissertation analyzes recent playwrights' portrayals of twins and the playwrights' detailed explorations of the anxieties which drive the twins' relationships with each other and society. Recent playwrights have also employed twins to symbolize fears peripheral to the phenomenon of twins: anxieties which plagued these three decades play heavily into these …
Breaking The Silence: Toward An Understanding Of Speaking Up In The Workplace., Sonya Fontenot Premeaux
Breaking The Silence: Toward An Understanding Of Speaking Up In The Workplace., Sonya Fontenot Premeaux
LSU Historical Dissertations and Theses
Although management scholars and practitioners emphasize the importance of employee input to organizational success, research suggests that many workers are hesitant to express an opinion or voice a view because they fear repercussions. In this dissertation, I focus on the issue of employee workplace expression, introducing the concept of speaking up. I define speaking up as "openly stating one's views or opinions about workplace issues." Speaking up is distinguished from several related concepts that fall within a common construct space. Drawing on expectancy theory (Vroom, 1964) and the theory of planned behavior (Ajzen, 1988, 1991), I explain the process believed …
The Effect Of Calcium Silicate On Rice Yield And Sheath Blight Disease., Chris Raymond Robichaux
The Effect Of Calcium Silicate On Rice Yield And Sheath Blight Disease., Chris Raymond Robichaux
LSU Historical Dissertations and Theses
Sheath blight caused by fungal pathogen Rhizoctonia solani can cause significant yield loss in rice, especially in warm, high rainfall environments. Integrated pest management (IPM) is the key to sheath blight control. This system utilizes disease resistance, pesticides, cultural practices and biological control to control multiple pests. Silicon fertilization is an additional cultural practice that can reduce sheath blight severity and increase grain yield. Studies were conducted in the greenhouse and field to determine the effect of calcium silicate on sheath blight severity, rice grain yield, and leaf silicon concentration. Results in the greenhouse study showed that sheath blight severity …

Understanding The Connections Between High-Stakes Test Consequences And School Literacy Experiences., Deborah Karen Setliff
LSU Historical Dissertations and Theses
The purpose of this ethnographic study was to connect the remedial summer school experiences of two fourth-grade students and four fifth-grade students with their school literacy experiences the following year. Understanding the students' experiences and connecting the experiences with school personnel provided a link between the students' and school personnel's perceptions of high-stakes testing consequences. Bridging these perceptions through cross-case analysis revealed the physical, emotional, and philosophical effects high-stakes testing is having on the students, school administrators, classroom teachers, and reading curriculum and instruction at the two elementary schools studied. Integrating the findings at the two schools helped develop a …

Oral Poetry In A Literate Culture: A Performance Ethnography Of Poetry Slams., Ramon Lavelle Sibley Jr
LSU Historical Dissertations and Theses
Poetry slams are competitive poetry performances that have drawn increasing public attention in the last decade. Despite their widespread popularity, few people outside the poetry slam community understand the nature of the slam's appeal. This study examines the organizational culture of poetry slams, and attempts to define the characteristics that contribute to its meaning, value and success for those who participate in them. This study describes four poetry slams that took place in Baton Rouge, Louisiana, during the months of June and July, 1999. An ethnographic approach is used to describe these events in terms of three variables: (a) the …
