The Chicano Mural Movement Of The Southwest: Populist Public Art And Chicano Political Activism, John Kenny Dec 2006

The Chicano Mural Movement Of The Southwest: Populist Public Art And Chicano Political Activism, John Kenny

University of New Orleans Theses and Dissertations

This work examines an art movement that was a direct outgrowth of a populist civil rights movement of the late 1960’s in the Southwest United States. This art, the Chicano Murals created as part of el Movimiento in San Diego, California was intended primarily as a didactic communication medium to reach into the barrios and marginalized neighborhoods for the primary purpose of carrying a resistance message to the semiliterate mestizo population within. Its secondary purpose was to bring a message from within these minority neighborhoods outward to the privileged elite, both Anglo and Hispanic, that within the confines of the …

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

University of 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 …

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

Novel Synthetic Routes To Formation Of Magnetic Nanocomposites, Anindya Pradhan

University of 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 …

Becoming And Un-Becoming, Monica Zeringue Dec 2006

Becoming And Un-Becoming, Monica Zeringue

University of New Orleans Theses and Dissertations

My work is about becoming and un-becoming. I seek to capture a time of transition and possibility. The pre-pubescent girls in my drawings are actually reduced versions of me, going back to a time of innocence and potential, and I multiply them as a means of selfexploration. They split apart, re-combine, and re-configure, trying to make a new whole. They are rendered with detailed accuracy, yet the world around them is empty, like a partially recalled memory. In this thesis, I will explore the use of the self-portrait, twinning, and re-configuration as they relate to identity, memory, and nostalgia. I …

Detecting Routing Misbehavior In Mobile Ad Hoc Network, Kejun Liu Dec 2006

Detecting Routing Misbehavior In Mobile Ad Hoc Network, Kejun Liu

University of New Orleans Theses and Dissertations

Routing misbehavior in MANETs (Mobile Ad Hoc Networks) is studied in this thesis. In general, routing protocols for MANETs are designed based on the assumption that all par- ticipating nodes are fully cooperative. However, due to the open structure and scarcely available battery-based energy, node misbehaviors may exist. One such routing misbehavior is that some selfish nodes will participate in the route discovery and maintenance processes but refuse to forward data packets. Therefore, we propose the 2ACK scheme that serves as an add-on technique for routing schemes to detect routing misbehavior and to mitigate their adverse effect. The main idea …

Government Ownership, Firm Value And Choice Of Seo Methods--- Evidence From Privatized Chinese Soes, Ohannes Paskelian Dec 2006

Government Ownership, Firm Value And Choice Of Seo Methods--- Evidence From Privatized Chinese Soes, Ohannes Paskelian

University of New Orleans Theses and Dissertations

In 1991, the Chinese government started the privatization process. A distinguishing feature of this privatization process is the presence of the government as a major shareholder in the privatized SOEs which creates a unique ownership structure that affects the firm performance, and, in turns its choice of equity issuing method. This dissertation investigates the relation between ownership structure, firm value, and the choice of equity offering method of the Chinese semi-privatized former state-owned enterprises. The dissertation consists of two essays. The first essay examines this relationship during the period 1993-1998 when the Chinese stock exchanges were at the infancy stage. …

Digital Dissection Of Radiographs, Using The Early Cretaceous Bird Confuciusornis And Photoshop Cs2tm, Sirelious White Dec 2006

Digital Dissection Of Radiographs, Using The Early Cretaceous Bird Confuciusornis And Photoshop Cs2tm, Sirelious White

University of New Orleans Theses and Dissertations

In the past, radiographs (x-ray "shadowgraphs") have been used by paleontologists as ways to identify and capture bone images. Primarily, this was done to examine the skeletal elements without having to remove the surrounding matrix. Radiographs have so much three-dimensional information compressed onto a two-dimension image that it is often impossible to understand the entire skeleton. Obviously, it would be desirable to strip away the readily interpretable skeleton elements and examine those less well understood. An initial set of experiments were performed on a particular section of a radiograph of Confuciusornis sanctus, as a subject, while utilizing Photoshop CS2TM to …

Onset And Persistence Of Biogenic Meromixis In A Filling Pit Lake-A Limnological Perspective , Oscar Flite Dec 2006

Onset And Persistence Of Biogenic Meromixis In A Filling Pit Lake-A Limnological Perspective , Oscar Flite

All Dissertations

Open pit mining usually results in a void that, over time, fills with water and becomes a pit lake. The goal for pit lakes is to create sustainable systems that positively contribute to local and regional watersheds. One long-standing hypothesis for attaining the goal of sustainability has been to create and maintain meromictic lakes (lakes that do not completely mix on a yearly cycle). It is believed that meromixis minimizes atmospheric oxygen exposure to pit walls and concomitant acid generation and minimizes reentrainment of metals to the upper waters during seasonal mixes. This seems to be a reasonable goal but …

A Program Of Self-Esteem Development For Deaf Children In Rural Areas, Candi Daviton Dec 2006

A Program Of Self-Esteem Development For Deaf Children In Rural Areas, Candi Daviton

Theses

Deaf children in rural areas often lack the development of self-esteem essential to their overall development of social and academic skills. Deaf children in rural communities generally have low interpersonal communication and leadership skills. Being isolated with no role model for their identification (deafness) could limit their language acquisition and identity development. The purpose of this project is to develop a special curriculum project which would help initiate a program that would enable deaf children in rural areas to develop self-esteem skills through a one week summer camp program focusing on learning about themselves and related essential self-esteem skills through …

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

University of 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 …

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

University of 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

University of 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 …

Bloom Filters For Filesystem Forensics, Rachel Bourg Dec 2006

Bloom Filters For Filesystem Forensics, Rachel Bourg

University of New Orleans Theses and Dissertations

Digital forensics investigations become more time consuming as the amount of data to be investigated grows. Secular growth trends between hard drive and memory capacity just exacerbate the problem. Bloom filters are space-efficient, probabilistic data structures that can represent data sets with quantifiable false positive rates that have the potential to alleviate the problem by reducing space requirements. We provide a framework using Bloom filters to allow fine-grained content identification to detect similarity, instead of equality. We also provide a method to compare filters directly and a statistical means of interpreting the results. We developed a tool--md5bloom--that uses Bloom filters …

Protecting Mobile Ad Hoc Networks From Spurious Cts Attacks 'Carrier Sensing Based Deferral Mechanism', Sreekanth Pagadala Dec 2006

Protecting Mobile Ad Hoc Networks From Spurious Cts Attacks 'Carrier Sensing Based Deferral Mechanism', Sreekanth Pagadala

University of New Orleans Theses and Dissertations

The Request-To-Send (RTS)/Clear-To-Send (CTS) mechanism is used to combat Hidden/Exposed node problems in Mobile Ad Hoc Networks (MANETs). The popular implementation of the RTS/CTS mechanism may lead to virtual blocking of the wireless medium. Problem arises if a malicious node randomly sends out a large number of spurious CTS frames in order to falsely block regular nodes in its neighborhood. Such an attack is termed as spurious CTS attack. In this thesis, we investigate the effects of such spurious CTS attacks and propose a solution to mitigate the problem. Our proposed solution, Carrier Sensing based Deferral (CSD) mechanism, asks nodes …

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

University of 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 …

Coping With Stress In Children, Tolonda Age Dec 2006

Coping With Stress In Children, Tolonda Age

University of 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

University of 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, …

Nanocrystalline Transition Metal Ferrites Synthesis, Characterization And Surface Functionalization, Daniela Caruntu Dec 2006

Nanocrystalline Transition Metal Ferrites Synthesis, Characterization And Surface Functionalization, Daniela Caruntu

University of New Orleans Theses and Dissertations

In this thesis, a new synthetic methodology for the high yield synthesis of spineltype transition metal ferrite nanoparticles has been developed. This approach is based on the complexation of the first-row transition metal cations with diethylene glycol (DEG) followed by the hydrolysis of the resulting chelate iron alkoxide complexes in the presence of an alkaline hydroxide. Due to the passivation of their surfaces with DEG molecules, the as-prepared nanoparticles are stable against agglomeration and can be easily dispersed in polar protic solvents (water, alcohols, etc.). Alternatively, a postsynthesis passivation with carboxylate ions can render the iron oxide nanocrystals highly dispersible …

Transformation Of Gossypium Hirsutum And Gossypium Barbadense By Rhizobium Rhizogenes: Hairy Root Induction And Gossypol Production, Stephanie Moss

University of New Orleans Theses and Dissertations

Gossypol and its methylated derivatives are produced in the leaves, seeds, stems, and roots of cotton plants. Although gossypol is toxic to many animals, other uses for gossypol are actively being investigated. To develop an experimental model for gossypol biosynthesis, a project to produce hairy root cultures from cotton was initiated. Hairy root cultures from two cotton species, Gossypium hirsutum (DPL 90) and Gossypium barbadense (Sea Island) were developed in this study. Gossypol was synthesized and retained by hairy root tissue at levels similar to that found in cottonseed. Cultures originating from a single transformation event were more similar in …
