Models Of Professional Development For Teachers: Factors Influencing Technology Implementation In Elementary Schools., Marilyn Hill Catchings

LSU Historical Dissertations and Theses

This qualitative multiple case study explored factors which contribute to the implementation of technology in elementary schools. This research had a phenomenological focus because there was a concentration on the structure and essence of the experiences of the teachers and leaders in the phenomenon, the implementation of technology in the school. The four schools chosen for the study were judged to have outstanding technology implementation by state technology leaders and a researcher screening process. They were selected because the researcher determined that these cases were the ones from which the most could be learned. These particular schools had ample technology …

Advanced Oxidation Processes For Remediation Of Explosives -Contaminated Soils., Elizabeth Covington Fleming

LSU Historical Dissertations and Theses

Explosives contamination in soils is an environmental concern for the public due to their toxic effects. The United States Department of Defense (DoD) is particularly concerned with explosives contamination in soils due to the thousands of sites for which it is responsible for remediating. To date, the most common technology utilized for remediating explosives contamination in soils has been incineration. However, costs for incineration have been estimated to range from approximately $250 to $3250 per ton and are generally inversely related to the volume of soil. The use of advanced oxidation processes (AOPs), including dark and illuminated forms, was evaluated …

Validation Of A Screening Instrument For Exposure To Violence In Children: The Kid -Save., Anise Lavaun Flowers

LSU Historical Dissertations and Theses

Children in the United States have an increasing rate of exposure to chronic community violence. Research on children exposed to community, domestic, and war-related violence has demonstrated the traumatic effects of violence on children. The KID-SAVE was developed as an empirically-based self-report measure of violence exposure for children in grades three through seven. During an initial development study, the KID-SAVE demonstrated excellent reliability and preliminary construct validity data. The purpose of the present study was to provide further validity data on the KID-SAVE. A sample of 188 children (96 boys and 92 girls) and their parents participated in the study. …

Human Caring, Self-Efficacy Beliefs, And Professional Organizational Culture Correlates Of Employee Retention In Child Welfare., Alberta June Shelinbarger Ellett

LSU Historical Dissertations and Theses

This study was designed to explore individual and organizational factors useful in explaining retention of professional staff in public child welfare agencies. The study examined linkages among a set of theoretically grounded personal/psychological and organizational variables and child welfare professionals' expressed intentions to remain employed in child welfare. Typically, studies in human services organizations have focused on issues pertaining to employee turnover and burnout. Alternatively, this study addressed personal and organizational factors related to employee retention in child welfare. The study used large sample survey and quantitative data analysis methods to examine relationships among elements of professional organizational culture, human …

Indices Of Exposure To Polycyclic Aromatic Hydrocarbons In A Bioindicator Species: Point Mutation Detection In The Cotton Rat., Christine H. Lemarchand-Carpentier

LSU Historical Dissertations and Theses

Release of energy-related contaminants occurs ubiquitously in the environment. Cancer induction by polycyclic aromatic hydrocarbons (PAHs) and aromatic amines have been well recognized in the workplace and are also suspected among the general population. Environmental PAHs exposure and effects have been investigated using biomarkers in aquatic and, to a lesser extent, terrestrial animals. Attempts to monitor the presence and effects of PAHs through the detection of point mutations in genes involved in carcinogenesis (p53 and K-ras) would yield interesting clues regarding possible etiologic agents and their potential effect. The identification of a mutation type, known to be G→T transversion predominantly …

The Sociolinguistic Situation Of Creoles In South Louisiana: Identity, Characteristics, Attitudes., Megan Elizabeth Melancon

LSU Historical Dissertations and Theses

Most of the research done on the Louisiana Creole community has concentrated on the vocabulary and folklore of Creole French. To date, there has been no methodological examination of other parameters enveloping the community. In this dissertation, the previous findings will be extended by analyzing the results of a survey on the linguistic attitudes and cultural, ethnic, and racial identity of the African-Americans in South Louisiana who identify as Creole. Due to the presence of several varieties of French in the state, the ethnic and racial admixture among the people who speak these dialects, and the overwhelming presence of English …

Infrared Dust Emission In Starburst Galaxies: Self-Consistent Modeling From The Uv To Far Infrared., Karl Anthony Misselt

LSU Historical Dissertations and Theses

In the first part of this thesis, the ultraviolet extinction from dust in the Large Magellanic Cloud is re-analyzed. Differences in the extinction properties between different lines of sight, as well as between the LMC, SMC, and Milky Way are discussed in the context of their implications for the constitution and size distributions of the dust grains. The UV extinction curves derived in this work, along with those from other studies, have been used to constrain dust models used as inputs to dust heating models. Next, the DIRTY model, a Monte Carlo radiative transfer code from the ultraviolet to the …

Francis Hayman: An Artist Reading British Literature In The 1740s., Stephen Alan Raynie

LSU Historical Dissertations and Theses

The on-going comparison of the sister arts (poetry and painting) in the eighteenth century recommends a reassessment of Francis Hayman's role as an artist reading and interpreting literary texts. A founding member of the Royal Academy in 1768, Francis Hayman began his artistic career as a scene painter at the Goodman's Fields and Drury Lane theaters. Although Hayman was one of the most prolific book illustrators in mid eighteenth century Britain, relatively little critical attention has been devoted to his work. Moreover, his circle of friends included such Old Slaughter's and St. Martin's Lane Academy regulars as Henry Fielding, William …

Pathogenesis Of Bartonella Henselae In The Domestic Cat: Use Of A Pcr-Based Assay For The Detection And Differentiation Of B. Henselae Genotype I And Genotype Ii In Chronically Infected Cats., Alma Faye Roy

LSU Historical Dissertations and Theses

Bartonella henselae is a zoonotic agent in which the domestic cat serves as the natural reservoir, and humans acquire potentially serious infections associated with this microorganism. The purpose of this research is to contribute to the understanding of the pathogenesis of B. henselae in the domestic cat using a molecular approach. Using sequence differences in a portion of the I 6S rRNA gene between B. henselae genotype I, and B. henselae genotype II, a nested polymerase chain reaction (nPCR) was designed and used to investigate various phases of feline bartonellosis. The nPCR detected 3.2 organisms per milliliter of blood which …

"A Secret! A Secret!": Confession And Autobiography In The Poetry Of Robert Lowell, Sylvia Plath, And Ted Hughes., Helen Lynne Sugarman

LSU Historical Dissertations and Theses

This study explores the impact of changing definitions of confession on the critical reception and interpretation of the poetry of Robert Lowell, Sylvia Plath, and Ted Hughes. In light of the ongoing criticism concerning "confessional poetry" in the forty-one years since Robert Lowell's Life Studies (1959) was published, it may seem difficult to justify yet another study of confessional poetry. However, the term has been so thoroughly assimilated into our critical vocabulary that we have lost an authentic sense of its meaning. "Confessional poetry" is in some ways an arbitrary term that has a very tenuous connection with the poetry …

Boron -Uptake Mechanisms And Boron Nutrition Of Rice., Xiaohe Yu

LSU Historical Dissertations and Theses

There are very few studies on B deficiency in rice (Oryza sativa L.). Reported critical values of B deficiency in rice are contradictory and mechanisms of B uptake by plant are not understood. Objectives of this study were to determine B effects on rice grown in hydroponics and soil; to determine critical values of B deficiency in rice tissues, hydroponic solution and soil; and to explore B-uptake mechanisms in both monocots (rice) and dicots (soybean (Glycine max L.)). Rice was grown to maturity in an acid Caddo silt loam at 0 and 1 kg B ha--1 in a greenhouse study, …

Structuring Work And Family Lives: Flexible Employment Patterns Among United States Families., Melissa Oliver Stainback

LSU Historical Dissertations and Theses

This dissertation focuses on how working families use flexible employment to manage multiple demands associated with combining work and family responsibilities. I argue that flexible employment outcomes are family adaptive strategies and decisions about these strategies are embedded in the household and occur in a context in which husbands and wives make joint decisions about their career trajectories, family obligations and community commitments. Therefore, I expect household models, rather than individual models, to provide a richer understanding of decisions about family and employment outcomes. These models explore more fully how couples may diversify employment participation. Furthermore, household level variables provide …

Evaporative Mass Transfer Of Hydrophobic Organic Compounds From Exposed Contaminated Sediment And Dredged Materials., Raghunathan Ravikrishna

LSU Historical Dissertations and Theses

Dredged sediment materials stored in confined disposal facilities (CDF) contain several hydrophobic organic compounds (HOC) such as polynuclear aromatic hydrocarbons (PAH), some of which are suspected carcinogens. The primary objective of this study was to evaluate the volatilization of HOCs from contaminated, exposed sediment dredged materials and contribute to the risk assessment framework being developed by the U.S. Army Corps of Engineers. Laboratory experiments were performed to measure HOC tracer emissions to air from contaminated sediments (laboratory inoculated and field aged) placed in a specially designed flux chamber. Flux was influenced by a number of factors such as relative humidity …

Environmental Education Programming For The Louisiana Cooperative Extension Service., John William Branch

LSU Historical Dissertations and Theses

Environmental education is a component of community-based education programs. Environmental education in the United States and in Louisiana was described (Objectives 1 and 2). Because of rapid changes in environmental science, and the responses of citizens to environmental topics, extension faculty need additional programming techniques and more process and strategic skills training. Programming techniques and skills training were reviewed (Objective 3). Extension has included representatives from key state and federal agencies with expertise in, and responsibility for, environmental topics on its environmental education advisory committees. The Delphi technique was utilized in this study, with agency representatives as panelists, to determine …

Alcohol Abuse And Violent Crime: A Contemporary Examination And Comparison Of Adult Male And Female Violent And Nonviolent Criminal Offenders., Don Randall Haley

LSU Historical Dissertations and Theses

The focus of this study was to investigate the relationship between violent criminal activity and alcohol abuse, and to further extend the knowledge about these phenomenon which currently appear in the literature. The association between these two variables has been asserted for many years, but few definitive correlations have been established using representative data. This study sought to determine if a statistical relationship exists between alcohol abuse rates of inmates serving time in Louisiana and their convictions for violent crimes. The research design used to investigate the relationship between alcohol abuse and violent criminal behavior was non-experimental and correlational. Interviews …

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe

LSU Historical Dissertations and Theses

Obesity, a recognized health problem, is associated with cardiovascular disease, diabetes and hypertension. Removal of adrenal steroids by adrenalectomy (ADX) slows the development of obesity. Leptin decreases food intake through effects initiated by activation of the JAK-STAT pathway. Defects in leptin signaling lead to obesity, which is associated with hyperleptinemia and leptin resistance. In chapter 4, leptin induces phosphoenolpyruvate carboxykinase (PEPCK) mRNA expression and increases glucose production in hepatocytes from lean but not obese Zucker rats. This suggests that hyperleptinemia in obesity causes hyperglycemia. In chapter 5, ADX decreased the levels of PEPCK mRNA, and increased leptin receptor mRNA expression …

Regulation Of Signal Transducers And Activators Of Transcription (Stats) By Effectors Of Adipogenesis: Coordinate Regulation Of Stats 1, 5a, And 5b With Peroxisome Proliferator-Activated Receptor-Γ And C/Aaat Enhancer Binding Protein-Α, William C. Stewart, Ron F. Morrison, Sherry L. Young, Jacqueline M. Stephens

Faculty Publications

We have recently demonstrated that three signal transducers and activators of transcription (STAT) family members are induced during adipocyte differentiation (Stephens et al., J. Biol. Chem. 271 (1996) 10441- 10444). Since STATs 1, 5A, and 5B are induced during adipocyte differentiation, we have examined the ability of these proteins to be regulated by components of the differentiation cocktail. In addition, we have examined the effects of potent effectors of differentiation on STAT protein expression during adipogenesis. A negative effector, tumor necrosis factor-α (TNFα), and a positive effector, a thiazolidinedione, were used in these experiments. Our results demonstrate that the expression …

Phytochelatin Synthase Genes From Arabidopsis And The Yeast Schizosaccharomyces Pombe, Suk Bong Ha, Aaron P. Smith, Ross Howden, Wendy M. Dietrich, Sarah Bugg, Matthew J. O'Connell, Peter B. Goldsbrough, Christopher S. Cobbett

Faculty Publications

Phytochelatins (PCs), a family of heavy metal-inducible peptides important in the detoxification of heavy metals, have been identified in plants and some microorganisms, including Schizosaccharomyces pombe, but not in animals. PCs are synthesized enzymatically from glutathione (GSH) by PC synthase in the presence of heavy metal ions. In Arabidopsis, the CAD1 gene, identified by using Cd-sensitive, PC-deficient cad1 mutants, has been proposed to encode PC synthase. Using a positional cloning strategy, we have isolated the CAD1 gene. Database searches identified a homologous gene in S. pombe, and a mutant with a targeted deletion of this gene was also Cd sensitive …

Interpretative Planning For A Neglected Historic Site In Istabul, Turkey, Ulvi Erhan Erol

LSU Historical Dissertations and Theses

In the 20th Century, war and other misfortunes have taught us to protect our historic and archeological past, in terms of both buildings and landscapes. While the world has already lost much of the past, much remains to be discovered, protected and interpreted. In the small pocket of urban open space located in Istanbul, Turkey that is the subject of this study, for example, the past usage's have been obliterated by contemporary employment of the site for automobile parking. This study presents an alternative way to use the site that takes better advantage of its central location among world-famous antiquities. …

Dark Phoenix: The Representation Of Black Woman In Je Suis Martiniquais By Mayotte Capecia And Mon Examen De Blanc By Jacqueline Manicom, Sybil Shevron Jackson

LSU Historical Dissertations and Theses

Black women writers in the French West Indies were conspicuously absent from the literary canon during the negritude movement in the 1940's. Mayotte Capecia was one of the few who managed to write during this time. Capecia was criticized severely for her novel Je suis Martiniquais by Frantz Fanon and accused of betraying her race because of the inter-racial love affair between her heroine and a French soldier. Jacqueline Manicom, her literary descendant who wrote Mon Examen de Blanc in 1972, was ostracized from the medical profession for her political beliefs concerning women's rights.

Diet Overlap Of Native And Translocated Northern White-Tailed Deer In Southeastern Louisiana, Brian Matthew Zielinski

LSU Historical Dissertations and Theses

I used microhistological analysis of fecal pellets to estimate and compare seasonal diet compositions between free-ranging, southern and translocated. northern woodland white-tailed deer (Odocoileus virginianus) on Golden Ranch Hunting Farm, Gheens, Louisiana,. over four consecutive seasons, from January 1997 through January 1998. I analyzed pellet groups with Near Infrared Reflectance Spectroscopy (NIRS) and wet chemistry techniques to evaluate and compare crude protein levels between populations of deer and provide indices of diet quality. On average, native and translocated deer diets were 87.65% similar during the entire study, and were significantly associated during all seasons ( P < 0.0000 I ). suggesting that deer fed on similar plant species in like quantities throughout the year. Few differences were found in plant selection frequencies per fecal sample. hut significant differences were detected (P 0.00 l) among deer populations in the use of Berchemia scandens and Vitis rotundifolia during spring. Northern deer also ingested a greater diversity of plants (P < 0.05) during spring and winter; and fecal crude protein levels were similar (P > 0.05) in all seasons …

The Boundaries Of The Silenced Hmr Domain In Saccharomyces Cerevisiae, David Donze, Christopher R. Adams, Jasper Rine, Rohinton T. Kamakaka

Faculty Publications

The chromosomes of eukaryotes are organized into structurally and functionally discrete domains that provide a mechanism to compact the DNA as well as delineate independent units of gene activity. It is believed that insulator/boundary elements separate these domains. Here we report the identification and characterization of boundary elements that flank the transcriptionally repressed HMR locus in the yeast Saccharomyces cerevisiae. Deletion of these boundary elements led to the spread of silenced chromatin, whereas the ectopic insertion of these elements between a silencer and a promoter blocked the repressive effects of the silencer on that promoter at HMR and at telomeres. …
