Active Response Of Polymer Materials From External Stimuli – Solvents And Light; Grafting Reactions On Perovskite Layers, Jianxia Zhang

LSU New Orleans Theses and Dissertations

The active response of a series of polymeric materials was investigated. Both solvent activated and light activated thin films and wire systems show dynamic behaviors when exposed to different stimuli.

Solvent mediated fluxional behavior of polymer thin films involved extensive, rapid curling both on infusion and evaporation of good solvents. These films can be either lab-fabricated ones or commercial ones, and the curling behavior can be as fast as seconds. Conditions including polymer materials, chosen solvents, and film geometry can affect the behavior.

Methods that allowed for the creation and retention of distorted wire structures were also developed; the asymmetric …

Controlled Attachment Of Nanoparticles To Layered Oxides, Yuan Yao

LSU New Orleans Theses and Dissertations

A series of oxide materials were modified with different nanoparticles (NPs). Novel cobalt@H₄Nb₆O₁₇ nanopeapod structures were fabricated and magnetic NPs modified oxide nanosheets and nanoscrolls were prepared. Both aqueous method and two-phase method were applied to prepare gold NPs onto oxide nanosheets, nanoscrolls and other nanocrystals.

The combination of H₄Nb₆O₁₇ nanoscrolls and cobalt NPs generate a novel method to fabricate nanopeapod structures. Cobalt NPs were synthesized in the presence of exfoliated H₄Nb₆O₁₇ nanosheets and the resulting magnetic chain structures, formed due to the dipole-dipole interaction, …

Phylogenetic Relationships And Character Evolution Of The Neotropical Butterfly Genus Hamadryas (Nymphalidae: Biblidinae), Ivonne J. Garzon

LSU New Orleans Theses and Dissertations

The butterflies in the genus Hamadryas are popular and noticeable representatives of the Neotropical Lepidoptera fauna. After a thorough taxonomic revision, 20 species were acknowledged within the genus, however no hypothesis of their phylogenetic relationship was proposed. The present dissertation provides a step further into the understanding of this fascinating group of butterflies not only by proposing the first phylogenetic hypothesis for the genus based on morphological and molecular data, but also by exploring for the first time in a group of butterflies the potential effect of venation associated with an specific behaviour on wing shape. Furthermore, this dissertation provides …

Racial Reproductive Control Logics And The Reproductive Justice Movement, Nicole Jolly

LSU New Orleans Theses and Dissertations

The reproductive justice movement gives a voice and representation to women of color whose experience of reproductive control is impacted by intersecting layers of oppression. This thesis uses an intersectional approach to develop the concept of racial reproductive control logics, which describes the relationship between racial logics and racial patterns of reproductive control. The study uses qualitative interviews and content analysis of organizational material to explore how the reproductive justice movement is influenced by racial reproductive control logics.

An Investigation Of The Combined Assessments Used As Entrance Criteria For A Gifted English Middle School Program, Colleen D. Lindsey Ph.D.

LSU New Orleans Theses and Dissertations

The purpose of this study was to determine if the four assessments for entrance into an academic middle school gifted English program were accurately predicting success, as measured by students’ grades each nine-week grading period. Some students were dismissed from the program each year because they could not maintain the required minimum average of 80%. The four entrance assessments evaluated were the Cognitive Abilities Test (CogAT), Naglieri Nonverbal Ability Test (NNAT), STEP Writing test, and the Iowa Test of Basic Skills: Reading (ITBS). The sample consisted of 150 sixth, seventh, and eighth grade students studied longitudinally over the span of …

When Is It Our Time?: An Event History Model Of Lesbian, Gay, And Bisexual Rights Policy Adoption, Megan E. Osterbur

LSU New Orleans Theses and Dissertations

Gays and lesbians have long struggled for their rights as citizens, yet only recently has their struggle been truly politicized in a way that fosters mobilization. When and why social movements coalesce despite the many obstacles to collective action are fundamental questions in comparative politics. While examining social movements is worthwhile, it is important to examine not only when and why a social movement forms, but also when and why a social movement is successful. This dissertation tackles the latter of these objectives, focusing on when and why social movements have success in terms of their duration from the time …

The Closure Of New Orleans' Charity Hospital After Hurricane Katrina: A Case Of Disaster Capitalism, Kenneth Brad Ott

LSU New Orleans Theses and Dissertations

Abstract

Amidst the worst disaster to impact a major U.S. city in one hundred years, New Orleans’ main trauma and safety net medical center, the Reverend Avery C. Alexander Charity Hospital, was permanently closed. Charity’s administrative operator, Louisiana State University (LSU), ordered an end to its attempted reopening by its workers and U.S. military personnel in the weeks following the August 29, 2005 storm. Drawing upon rigorous review of literature and an exhaustive analysis of primary and secondary data, this case study found that Charity Hospital was closed as a result of disaster capitalism. LSU, backed by Louisiana state officials, …

Factors Impacting Principals' Career Decision Making, Wylene M. Sorapuru

LSU New Orleans Theses and Dissertations

Abstract

Federal legislation and educational programs such as No Child Left Behind (2001) and Race to the Top (2009) identify school leaders as one of the major catalysts to improving academic achievement. Increasing accountability demands call for replacement of the principal when adequate gains in student achievement are not met, yet research indicates that it takes at least five years to affect change (Fullan, 2006). Why then would any principal remain in an appointment as principal in a chronically low-performing school?

New principals generally stay no more than five to ten years in any one position (Dancy, 2007; NAESP, 1998). …

Pattern Recognition Of Power System Voltage Stability Using Statistical And Algorithmic Methods, Varun Togiti

Characterization Of Altered Epithelial Cell Turnover And Differentiation In Embryonic Murine Lungs That Over-Express Receptors For Advanced Glycation End-Products (Rage), Jeffrey Alan Stogsdill

Theses and Dissertations

Receptors for advanced glycation end-products (RAGE) are multi-ligand cell surface receptors highly expressed in the lung that modulate pulmonary inflammation during disease. However, the contributions of RAGE signaling are unknown during pulmonary organogenesis. In order to test the hypothesis that RAGE misexpression adversely affects lung morphogenesis, conditional transgenic mice were generated that over-express RAGE in alveolar type II cells of the lung. When RAGE is over-expressed throughout embryogenesis, severe lung hypoplasia ensues, culminating in perinatal lethality. Flow cytometry and immunohistochemistry employing cell-specific markers for various distal cell types demonstrated anomalies in key epithelial cell populations resulting from RAGE up-regulation through …

Validation Of 3'-Deoxy-3'-[18f]-Fluorothymidine Positron Emission Tomography For Image-Guidance In Biologically Adaptive Radiotherapy, Marian Axente

Theses and Dissertations

Accelerated tumor cell repopulation during radiation therapy is one of the leading causes for low survival rates of head-and-neck cancer patients. The therapeutic effectiveness of radiotherapy could be improved by selectively targeting proliferating tumor subvolumes with higher doses of radiation. Positron emission tomography (PET) imaging with 3´-deoxy-3´-[18F]-fluorothymidine (FLT) has shown great potential as a non-invasive approach to characterizing the proliferation status of tumors. This thesis focuses on histopathological validation of FLT PET imaging specifically for image-guidance applications in biologically adaptive radiotherapy. The lack of experimental data supporting the use of FLT PET imaging for radiotherapy guidance is addressed by developing …

A Multigroup Analysis Of The Psychological Factors That Contribute To Persisting Working Attention Problems In Mild Traumatic Brain Injury And Chronic Pain, Kelly L. Curtis

LSU New Orleans Theses and Dissertations

A significant subset of mild traumatic brain injury (mild TBI) and chronic pain (CP) patients report, and sometimes show objective evidence of, persisting cognitive problems. Despite differences in injury mechanisms, there is considerable overlap in the types of persisting cognitive symptoms that are reported by the two populations. Psychogenic, rather than physiogenic, factors are thought to play an important role in the maintenance of these persisting symptoms. The current investigation examined the contributions somatization, depression, and anxiety had on an objective measure of “working attention.” In order to best elucidate the influences these psychological factors had on attentional performance, only …

Synthesis And Biological Evaluation Of Rigid Analogues Of Methamphetamines, Andrea N. Forsyth

LSU New Orleans Theses and Dissertations

A series of rigid azetidenyl-based methamphetamine analogs were synthesized from commercially available N-Boc-azetidinone. The benzylideneazetidine analogs were prepared via a Wittig olefination via the ylides generated from the corresponding triphenylphosphonium benzylhalide salts. The substituted benzylazetidine analogs were synthesized from the corresponding benzylideneazetidienes via hydrogention over palladium and platinum catalysts. The benzylideneazetidine and benzyliazetidine analogs were evaluated at monoamine transporters as a part of preliminary structure-activity study for the development of novel monoamine transporter ligands. The binding affinities of the azetidine analogs were determined at dopamine (DAT) and serotonin (SERT) transporters in rat brain tissue preparations. The preliminary in vitro …

Software For Estimation Of Human Transcriptome Isoform Expression Using Rna-Seq Data, Kristen Johnson

LSU New Orleans Theses and Dissertations

The goal of this thesis research was to develop software to be used with RNA-Seq data for transcriptome quantification that was capable of handling multireads and quantifying isoforms on a more global level. Current software available for these purposes uses various forms of parameter alteration in order to work with multireads. Many still analyze isoforms per gene or per researcher determined clusters as well. By doing so, the effects of multireads are diminished or possibly wrongly represented. To address this issue, two programs, GWIE and ChromIE, were developed based on a simple iterative EM-like algorithm with no parameter manipulation. These …

Deep Play, Urban Space, Adolescent Place: A Multi-Sited Study Of The Effects Of Settings On Adolescent Risk/Reward Behavior, Benjamin A. Shirtcliff

LSU New Orleans Theses and Dissertations

The extant literature on the play behavior of youth normalizes adolescent behavior in public space as transgressional, resistant, and in need of social control. The dissertation counters this trend by looking to see if physical qualities, peer effects, and neighborhood context of settings play a deeper role in youth behavior. The study documented urban context, peer effects, physical features, and play behavior across 21 urban settings in New Orleans. Unobtrusive observations employed a highly innovative technique based on YouTube videos and analyzed using hierarchical linear modeling. Coded observations of risk-taking and prosocial behavior demonstrated some stability in behavior amongst adolescents—“youth” …

Fish Assemblage Dynamics And Red Drum Habitat Selection In Bayou St. John And Associated Urban Waterways Located Within The City Of New Orleans, Louisiana, Patrick W. Smith Mr.

LSU New Orleans Theses and Dissertations

Bayou St. John (BSJ) and City Park Lakes and Lagoons (CPLL) are urban waterways in New Orleans, Louisiana. I studied habitat selection of red drum in BSJ, and fish assemblage change in BSJ and CPLL over 40 years. Temperature was found to be the best predictor of red drum habitat selection in Bayou St. John, while salinity and change in depth also were found to be good predictors for certain sites. Potential prey item abundance did not appear to influence habitat selection. Using data from 1971 – 2010, nearshore habitats in CPLL were affected by Hurricane Katrina, but have sense …

Examining The Relationship Between Louisiana Principals' Self-Efficacy Beliefs And Student Achievement, Jonathan C. Williams

LSU New Orleans Theses and Dissertations

Abstract

The purpose of this study was to examine the relationship between Louisiana Principals’ self-efficacy beliefs and student achievement. This study was grounded in the research of Bandura’s model of triadic reciprocal causation and more recent research on principals’ self-efficacy beliefs. Using the Principals’ Sense of Efficacy Scale (PSES) (Tschannen-Moran & Gareis, 2004) measures of principals’ self-efficacy were collected and analyzed for (1) instructional leadership, (2) management, and (3) moral leadership.

Principals across the state of Louisiana were emailed a link to the PSES and were asked to provide the names of their schools and asked for the number of …

Synthesis And Characterization Of Sugar Based Low Molecular Weight Gelators, Hao Yang

LSU New Orleans Theses and Dissertations

Low molecular weight gelators (LMWGs) have gained great attention over the past two decades. These compounds form self-assembled fibrous networks like micelles, cylindrical, sheets, fibers, layers and so on. The fibrous network entraps the solvent and form gel. LMWGs are interesting compounds with many potential applications in material and biomedical sciences.

Many different structures have been found to be good LMWGs. Our interests focus on the carbohydrate based LMWGs. Previously, we have found that several ester derivatives of methyl 4, 6-O-benzylidene-α-D-glucopyranoside are good gelators for organic solvents and aqueous solutions. In this study, in order to understand the …

Synthesis Of S-Ribosyl-L-Homocysteine And Analogs Modified At The Homocysteine-C3 Position, Ruoyi Liu

Master's Theses

Quorum sensing (QS) is a process of bacterial cell-to-cell communication that conveys population density information in order to coordinate gene expression to produce synchronized behaviors. QS regulates the expression of virulence genes in many species of bacteria; hence, the manipulation of QS pathways may lead to treatment options against many bacterial diseases. The LuxS enzyme converts S-ribosyl-L-homocysteine (SRH) into homocysteine (HCys) and 4(S),5-dihydroxypentane-2,3-dione (DPD), which is the precursor of autoinducer-2 (AI-2). Thus, inhibitors of LuxS could prevent QS by halting the conversion of SRH to AI-2 rendering the cell “uncommunicative”. This work shows the successful chemical synthesis …

Mitochondrial Haplotype Variation In Lake Sturgeon, Acipenser Fulvescens (Rafinesque, 1817), Of The Great Lakes Basin, Michelle Lynne Weatherell

Theses

Lake sturgeon, Acipenser fulvescens, is one of twenty-five extant species of sturgeon; five of which reside in North America. Despite being a part of one of the most ancient lineages of modern vertebrates (Actinopterygii: Acipenseriformes) and having a vast geographic range, their populations are dwindling. Without knowing if these populations are genetically diverse or impoverished, it is difficult to determine how conservation efforts should be continued to help save the "dinosaur" fish species. The hypothesis of this study was that populations of lake sturgeon, residing throughout the Great Lakes Basin and their tributaries are genetically depauperate; few mitochondrial haplotypes are …

The Effects Of Rhes, A Striatal Specific Protein, On The Expression Of Behavioral And Neuropathological Symptoms In A Transgenic Mouse Model Of Huntington's Disease, Brandon A. Baiamonte

LSU New Orleans Theses and Dissertations

Huntington's disease (HD) is a neuropsychiatric disorder characterized by choreiform movement of the limbs, cognitive disability, psychosis and dementia. It is untreatable, incurable, and ultimately fatal. HD is invariably associated with an abnormally long CAG expansion within the IT15 gene on human chromosome 4. Although the mutant huntingtin protein (mHtt) is ubiquitously expressed in HD patients, cellular degeneration occurs only in neurons within the striatum and cerebral cortex. The Ras homolog Rhes is expressed very selectively in the precise brain areas affected by HD. Recent work using cultured cells suggests that Rhes may be a co-factor with mHtt in cell …

The Persistence Of Vengeance From Early Modern England To Postmodern New York, Dominic M. Sevieri

LSU New Orleans Theses and Dissertations

As a passing glance at the popular texts of any given period reveals, the subject of vengeance is nearly inescapable; on billboards, websites, and year end lists, revenge represents a curious constant even amid disparate media. This study explores the cultural commonalities that align revenge texts of the English Renaissance and exploitation films of late 20th century America. As in-depth inquiry reveals, numerous ideas and narrative tropes popularized during the Early Modern period are pushed to their logical extremes in these films. The central factor that aligns London during the Renaissance and New York at the cusp of the 1990s …

Growing Support: Localism, Nonprofits, And Food Access In Post-Katrina New Orleans, Brent Tranchina

LSU New Orleans Theses and Dissertations

Problems with food insecurity, such as a lack of access to healthy and affordable food in low-income neighborhoods, has been an ongoing challenge in New Orleans. The damages inflicted by Hurricane Katrina and subsequent citywide flooding on the local food system reduced the numerical count of operational full-service supermarkets and grocery stores throughout the city. The result has been a widespread presence of food deserts and grocery gaps, particularly in low-income neighborhoods. This thesis explores the emergence of food localism practices by food advocacy professionals as a capacity-building tool for New Orleans residents to increase community food security and develop …
