Coping With Stress In Children, Tolonda Age Dec 2006

Coping With Stress In Children, Tolonda Age

LSU New Orleans Theses and Dissertations

Unique stressors can prompt child adjustment difficulties. Coping strategies and emotion regulation that impact the adjustment of children in general and military family children were investigated. Eighty children, 36 with deployed parents, their parents and teachers participated. All experienced stress related to hurricane Katrina. Correlational analyses indicate that children with more hurricane-related losses or moves, use some coping strategies less often; hurricane-related child distress is related to lower maternal support; and parental hurricane-related distress is associated with high levels of child externalizing problems. When dealing with general stressors, some coping strategies were positively associated with child internalizing problems. Analyses indicate …

Land Loss: Attachment, Place And Identity In Coastal Louisiana, David Burley Dec 2006

Land Loss: Attachment, Place And Identity In Coastal Louisiana, David Burley

LSU New Orleans Theses and Dissertations

This dissertation explores how people frame environmental change. Specifically, this work explores the identity loss that residents of coastal Louisiana experience due to coastal land loss. I rely on 126 in-depth interviews of residents from communities in six coastal parishes (counties). Respondents convey the meanings they give to land loss through constructing a narrative of place. A phenomenological approach is employed that focuses on how stories are told and the subjective interpretations of societal members. First, Louisiana's coastal communities hold a significant attachment to place that in many cases has been developing for close to three centuries. For most residents, …

Trade Relations Between Southern U.S. Cities And Latin America: A Study Of How The Port Cities New Orleans, Houston, And Miami Fare Against One Another Amid Increasing Competition For Trade With Latin America, Bethany Comboy Dec 2006

Trade Relations Between Southern U.S. Cities And Latin America: A Study Of How The Port Cities New Orleans, Houston, And Miami Fare Against One Another Amid Increasing Competition For Trade With Latin America, Bethany Comboy

LSU New Orleans Theses and Dissertations

Globalization has affected decentralization and greater centralized control and management within governments traditionally unconstrained by international change, city governments. City governments must be increasingly active internationally to survive in a politically decentralized global environment, especially in international trade. Trade is important to cities because it affects growth, jobs and standard of living among other contributors to local economies. The effects of globalization at the local level are manifested in three Southern U.S. cities with business-generating ports linked to Latin American and world markets: New Orleans, Houston, and Miami. This comparative case study considers the competition among New Orleans, Houston and …

(Re)Building Cultural, Community, And Academic Identity: Freshman Composition After Katrina, Russo Celeste Del Dec 2006

(Re)Building Cultural, Community, And Academic Identity: Freshman Composition After Katrina, Russo Celeste Del

LSU New Orleans Theses and Dissertations

Composition studies has become increasingly focused on the connection between place, identity, and the act of writing, maintaining, as theorist Nedra Reynolds states, that “where writing instruction takes place has everything to do with how” (20). Considering the social, political, and cultural contexts of a post-Katrina Southeastern Louisiana, administrators and instructors at the University of New Orleans must begin to question how our freshmen writing program can best serve our students as they enter into the future of a "new" New Orleans. Implementing a "localized pedagogy" into the freshmen composition classroom--that is, a community-based pedagogy that draws from local resources, …

The Mechanical Thermal And Microstructural Behaviors Of The Strip Silicates Reinforced Epoxy-Based Nanocomposites, Man Wai Ho Dec 2006

The Mechanical Thermal And Microstructural Behaviors Of The Strip Silicates Reinforced Epoxy-Based Nanocomposites, Man Wai Ho

LSU New Orleans Theses and Dissertations

Ten different sets of epoxy samples with compositions from 0wt% to 8wt% nanoclay were prepared by mechanical stirring and then casting to mold dog-bone shape samples for tensile and other tests. A gradual trend of changes upon mechanical, thermal and microstructural behaviors were investigated. Introduction of strip silicates inside the epoxy matrix contributed to higher tensile strength, flexural strength and Vickers' hardness. From tensile tests, the ultimate tensile strength of samples from 0wt% to 8wt% nanoclay ranged from 42MPa to 46MPa. The epoxy samples with 1wt%, 4wt% to 6wt% nanoclay had a stepwise increase in the ultimate tensile strength of …

Fair Housing Goes Nuclear: In Suburban Chicago The Cold War Meets A Civil Rights Protest In 1967, Ryan Mattingly Dec 2006

Fair Housing Goes Nuclear: In Suburban Chicago The Cold War Meets A Civil Rights Protest In 1967, Ryan Mattingly

LSU New Orleans Theses and Dissertations

In December of 1966 the United States government decided to place a $375 million atomic accelerator in the all-white, rural town of Weston, Illinois. The small town was located 30 miles west of Chicago, within an affluent suburban county named DuPage. Residents of DuPage were thrilled to receive the atomic installation because it would spark new economic growth in the area. However, the National Committee Against Discrimination in Housing (NCDH) immediately protested the approval of the Weston site. They opposed the site choice because of a documented history of racial housing discrimination in and around Weston. In 1967, the NCDH …

Purification Of Global Regulator, Spx, And Rna Polymerase From Staphylococcus Aureus For Use In In Vitro Transcription Of Redox Genes, Jane Mcbride Dec 2006

Purification Of Global Regulator, Spx, And Rna Polymerase From Staphylococcus Aureus For Use In In Vitro Transcription Of Redox Genes, Jane Mcbride

LSU New Orleans Theses and Dissertations

Spx is a global regulator discovered in Bacillus subtilis to suppress basal growth and development processes and activate transcription of genes involved in thiol homeostasis when a cell encounters oxidative stress. Its activity relies on reversible thiol-disulfide bond formation and binding RNA polymerase rather than DNA. The discovery that Staphylococcus aureus global virulence regulator, SarA, is more active upon cysteine reduction suggests that redox response could mediate virulence in this important human pathogen. We describe the cloning of spx from S. aureus strain RN6390, overexpression in Escherichia coli, and purification of native protein. Antibodies against Spx were raised for western …

Fire & Flood: How The Lessons Of The Past Can Apply To The Present To Build The Future, Jared Munster

LSU New Orleans Theses and Dissertations

On August 29, 2005 the most destructive natural disaster to ever befall the United States made landfall initially near Buras, Louisiana and then ultimately near the mouth of the Pearl River. The associated storm surge caused New Orleans' protective levee system to fail, inundating the City with brackish floodwaters for weeks on end. This was not the first time the City of New Orleans was crippled by disaster. In 1788 and 1794, the city suffered two major fires; the first burning 856 buildings and the second 212. These were significant losses in a city that had a building stock of …

Novel Synthetic Routes To Formation Of Magnetic Nanocomposites, Anindya Pradhan Dec 2006

Novel Synthetic Routes To Formation Of Magnetic Nanocomposites, Anindya Pradhan

LSU New Orleans Theses and Dissertations

Novel synthetic routes to formation of gold-magnetite nanoparticles have been designed by sonochemistry. Treatment of preformed magnetite nanoparticles with ultrasound in aqueous media with dissolved tetrachloroauric acid resulted in the formation of gold-magnetite nanocomposite materials. These materials maintained the morphology of the original magnetite particles. The morphology of the gold particles could be controlled by adjusting experimental parameters, including the addition of small amounts of solvent modifiers such as methanol, diethylene glycol, and oleic acid. Further experiments were conducted with silver and titanium. Morphology and properties of nanocomposites were analyzed by transmission electron microscope (TEM), energy dispersive spectra (EDS), superconducting …

Identification And Characterization Of A New Class Of Bilin Lyases In Synechococcus Sp. Pcc 7002, Nicolle Saunée

LSU New Orleans Theses and Dissertations

The goal of this research is to identify and characterize the enzymes (lyases) responsible for chromophore (bilin) attachment to phycobiliproteins (light harvesting) in cyanobacteria. Candidates for these lyases were first identified in Fremyella diplosiphon as cpeS and cpeT. In Synechococcus sp. PCC 7002, there are three cpeS-like genes (named cpcS, cpcU, and cpcV) and one cpeT-like gene (named cpcT). These genes were cloned, overexpressed, and purified from E. coli. The CpcS and CpcU proteins form a 1:1 complex and catalyze the addition of phycocyanobilin (PCB) to â-82 cysteinyl residue on phycocyanin (PC) in vitro. Tryptic digestion and C18 RP-HPLC confirmed …

A Parallel Architecture For Analog-To-Digital Conversion With Improved Dynamic Range, Brandy Sausse Dec 2006

A Parallel Architecture For Analog-To-Digital Conversion With Improved Dynamic Range, Brandy Sausse

LSU New Orleans Theses and Dissertations

In this thesis, a parallel architecture for Analog-to-Digital Converters (ADCs) is developed to increase the system dynamic range. The proposed architecture is a critical component for a Continuous Wave Stepped Frequency (CWSF) radar system. Existing Commercial Off-The-Shelf (COTS) components are inadequate to meet the demands of a high sample rate and a high dynamic range specification. The proposed parallel architecture meets the design criteria by extending the upper voltage limit of high sample rate converters. Extensive simulation study verifies that the desired high sample rate and increased resolution is achieved.

Anthony Eden, The Egypt Committee, And The Politics Of Prestige During The Suez Crisis, Alexander Shelby Dec 2006

Anthony Eden, The Egypt Committee, And The Politics Of Prestige During The Suez Crisis, Alexander Shelby

LSU New Orleans Theses and Dissertations

The impact of the Gamal Abdul Nasser's nationalization of the Suez Canal on Anthony Eden's policy making during the Suez Crisis is the bases of this research. Using data from the Cabinet records of Eden's Egypt Committee, this research will demonstrate that Eden and the Egypt Committee acted irrationally during the Suez Crisis and by doing so created a schism in the Atlantic Alliance. This rift would force President Dwight Eisenhower to side with the Soviet Union against Britain to resolve the conflict. The effects of the crisis caused the British to lose their prestige as a world power and …

Which Events Constitute Criteria A1 Of Ptsd? The Phenomenology Of Psychological Trauma In Youth, Leslie Katherine Taylor Dec 2006

Which Events Constitute Criteria A1 Of Ptsd? The Phenomenology Of Psychological Trauma In Youth, Leslie Katherine Taylor

LSU New Orleans Theses and Dissertations

The aim of this study was to explore the phenomenology of psychological trauma in youth. It was hypothesized that events reported as traumatic could be classified into one of seventeen trauma categories, that levels of impairment in traumatized youth would be higher than levels of impairment in non-traumatized youth, and that traumatic events reported would be differentially related to Posttraumatic Stress Disorder (PTSD) symptoms and types of cognitive errors. Information regarding traumas and PTSD symptoms was collected through The Child PTSD Checklist from a sample of youth aged 6 to 17. A coding system was developed for classification of traumatic …

Analysis Of Two Neighboring Miocene Paleo-Turbidite Systems In A Complex Deep-Water Environment: Implications For Biostratigraphic Techniques Used In Gulf Of Mexico Petroleum Exploration Studies, Andrew Tipton Dec 2006

Analysis Of Two Neighboring Miocene Paleo-Turbidite Systems In A Complex Deep-Water Environment: Implications For Biostratigraphic Techniques Used In Gulf Of Mexico Petroleum Exploration Studies, Andrew Tipton

LSU New Orleans Theses and Dissertations

Biostratigraphic techniques are commonly used in shallow environments of the Gulf of Mexico basin for depositional history modeling in petroleum exploration applications. Extending these interpretations to deep-water settings, where the structural and depositional history is more complex, is problematic. A localized study area was used for a case-analysis of a typically complex deep-water study area. A dataset of seismic, well-log, and biostratigraphic information was used to: (a) assess accuracy of the biostratigraphic interpretations produced by Fillon (2005), (b) determine specific pitfalls of micropaleontology as a tool in this environment, and (c) provide guidelines for the application of biostratigraphic data in …

Statistical Methods For Kinetic Modeling Of Fischer Tropsch Synthesis On A Supported Iron Catalyst, Brian L. Critchfield Dec 2006

Statistical Methods For Kinetic Modeling Of Fischer Tropsch Synthesis On A Supported Iron Catalyst, Brian L. Critchfield

Theses and Dissertations

Fischer-Tropsch Synthesis (FTS) is a promising technology for the production of ultra-clean fuels and chemical feedstocks from biomass, coal, or natural gas. Iron catalysts are ideal for conversion of coal and biomass. However, precipitated iron catalysts used in slurry-bubble column reactors suffer from high attrition resulting in difficulty separating catalysts from product and increased slurry viscosity. Thus, development of an active and selective-supported iron catalyst to manage attrition is needed. This thesis focuses on the development of a supported iron catalyst and kinetic models of FTS on the catalyst using advanced statistical methods for experimental design and analysis. A high …

Möbius: For Orchestra , Anthony Dominic-Paul Cipolone Dec 2006

Möbius: For Orchestra , Anthony Dominic-Paul Cipolone

LSU New Orleans Theses and Dissertations

Möbius: for Orchestra attempts to explore an alternative use of the material that typically appears in the development section of a piece composed in sonata form. By using the modified themes in the recapitulation rather than disregarding them entirely, the A-B-A' form of the basic sonata becomes more of an A-B-(A'+B'). Much like the mathematical function this piece is named after – a loop whose ending is never identical to its beginning and whose mirror-image lacks symmetry – the listener is brought to a new ending with familiar, non-repeated material. Many times throughout the piece, the listener will hear up …

Energy Efficient Cluster Head Selection In Fixed Wireless Sensor Networks, Irfanuddin Ahmed Dec 2006

Energy Efficient Cluster Head Selection In Fixed Wireless Sensor Networks, Irfanuddin Ahmed

LSU New Orleans Theses and Dissertations

Energy is the main bottleneck for wireless sensor networks and it has dominating effects on network lifetime. Sensors have finite energy and during the process of sensing and transmitting data to the cluster head they lose energy. Sensors that are furthest away from the cluster head require more energy than the closer ones. These losses of energy cause sensors to die faster, lower coverage area and hence network death. In this paper we investigate techniques to maximize the network lifetime by selecting the most optimal cluster head. The proposed technique is in context of cluster-based wireless sensor networks, the others …

Acoustic Seabed And Target Classification Using Fractional Fourier Transform And Time-Frequency Transform Techniques, Madalina Barbu Dec 2006

Acoustic Seabed And Target Classification Using Fractional Fourier Transform And Time-Frequency Transform Techniques, Madalina Barbu

LSU New Orleans Theses and Dissertations

An approach for processing sonar signals with the ultimate goal of ocean bottom sediment classification and underwater buried target classification is presented in this dissertation. Work reported for sediment classification is based on sonar data collected by one of the AN/AQS-20's sonars. Synthetic data, simulating data acquired by parametric sonar, is employed for target classification. The technique is based on the Fractional Fourier Transform (FrFT), which is better suited for sonar applications because FrFT uses linear chirps as basis functions. In the first stage of the algorithm, FrFT requires finding the optimum order of the transform that can be estimated …

Modern Foraminiferal Bio-Facies Within A Transgressive Saline Influenced Deltaic Headland, South-Central Louisiana, Chandra Dreher Dec 2006

Modern Foraminiferal Bio-Facies Within A Transgressive Saline Influenced Deltaic Headland, South-Central Louisiana, Chandra Dreher

LSU New Orleans Theses and Dissertations

Incorporating improved preparation techniques, modern taxonomy, and quantitative analysis of environmental variables known to influence marsh foraminifers in other coastal regions refined marsh foraminiferal biofacies of the Mississippi delta region. Elevation, pore water salinity, total carbon, and mean grain size were compared with foraminiferal distributions in a transgressive marsh system of the lower Lafourche headland of the south-central delta plain. Cluster analysis aided definition of two biofacies, one from the marsh interior and one from the marsh edge. The marsh edge biofacies was further subdivided into levee crest and bayou margin biofacies. Correlation analysis suggested that seven of the 21 …
