Theoretical Approaches To The Characterization Of Water, Aqueous Interfaces, And Improved Sampling Of Protein Conformational Changes, Alexis J. Lee

LSU New Orleans Theses and Dissertations

Methods to advance the understanding of water and other aqueous systems are devel- oped. This work falls into three areas: The creation of better interaction potentials for water, improved methods for sampling configurational space, and the applications of these methods to understand systems of interest. Charge transfer has been shown by ab initio methods to be important in the water–water and water–ion interactions. A model for treating charge transfer in liquid water and aqueous systems is presented in this manuscript. The model is called Discrete Charge Transfer (DCT) and is based on the commonly-used TIP4P/2005 model, which represents the charge …

The purpose of this dissertation is to examine the experiences of St. Bernard Parish, La., residents as they coped with the impact of the catastrophe of Hurricane Katrina on August 29, 2005. An estimated 50,000 St. Bernard Parish residents relocated to a new home one year after Katina in 2006, and many of those residents moved again. This study examines the effects of the decisions of St. Bernard residents to relocate or to return on their social connections. The utility, adaptability and durability of social networks of these residents will be explored to enrich our knowledge about the social effects …

Working Towards The Sustainability Of New Orleans’ African American Indigenous Cultural Traditions, Ethan K. Ellestad

LSU New Orleans Theses and Dissertations

New Orleans indigenous cultural traditions such as Mardi Gras Indians, Social Aid and Pleasure Clubs and second line parades were born out of the disenfranchisement of the African American community. Though the practices have existed for over a century and provide social benefits, they have faced hostility from the police department, indifference from elected officials and city planners, as well as economic exploitation, denying them the ability to thrive. With a restructuring of public policy and outside assistance, these cultural traditions will be able to help revitalize the economically depressed areas where they continue to be practiced.

Corporate Governance, Performance And Risk-Taking In The U.S. Banking Industry, Jennifer Osullivan

LSU New Orleans Theses and Dissertations

In this dissertation, we first examine the relationship between performance of the bank holding company and several board characteristics. We use five proxies for bank performance including Tobin’s Q, ROA, loan loss reserve ratio, non-performing asset ratio, and net charge-offs ratio. Board characteristic variables we include are board size, proportion of outsiders, CEO power, CEO tenure and board tenure. We find that a large board enhances bank performance, as proxied by Tobin’s Q and loan quality variables. We find no evidence that board structure or CEO power influences firm performance. We see that CEO and board tenure have a positive …

Design, Synthesis And Biological Evaluation Of Novel Cannabinoid Antagonist, Abha Verma

LSU New Orleans Theses and Dissertations

This study was aimed at the development of novel CB1 cannabinoid receptor antago­nists that may have clinical applications for the treatment of cannabinoid and psychostimulant addiction. The rationale for the design for our target was to incorporate a bioisosteric 1,2,3-triazole ring into the vicinal diaryl group revealed in the prototypical antagonist/inverse agonist SR141716 (Rimonabant) that was pre­sumed to interact with a unique region in the CB1 receptors. Based on our prelimi­nary results we identified a novel series of 1,2,3-triazole ester and keto deriva­tives as lead compounds for biological evaluation. Here in the design rationale, syn­thesis and CB1 receptor affinity for …

A Framework To Annotate The Uncertainty For Geospatial Data, Zhao Yang

LSU New Orleans Theses and Dissertations

We have developed a new approach to annotate the uncertainty information of geospatial data. This framework is composed of a geospatial platform and the data with uncertainty. The framework supports geospatial sources such as Geography Markup Language (GML) with uncertainty information. The purpose of this framework is to integrate the uncertainty information of data from the application users and thereby ease the development of processing uncertainty information of geospatial data. Having well organized data and using this framework, the end-users can store the uncertainty information on the current geospatial data structure. For example, a GIS user can share the error …

Two Essays In Financial Economics, Jatin Ravikant Malhotra

LSU New Orleans Theses and Dissertations

In the first chapter of this dissertation, I examine the relationship between hedging and diversification effects on CEO compensation in the Real Estate Investment Trust (REIT) industry. The REIT industry is suitable for this investigation for various reasons; primarily being that the REIT sample represents a relatively clean sample to study the effects of diversification and hedging on compensations. I find a positive and significant relationship between the interaction variable which reflects the effects of both hedging and diversification and CEO pay-for-performance sensitivity. This is consistent with the notion that managers are in a better position to manage firm risk …

Surface Functionalized Water-Dispersible Magnetite Nanoparticles: Preparation, Characterization And The Studies Of Their Bioapplications, Haiou Qu

LSU New Orleans Theses and Dissertations

Iron oxide magnetic nanoparticle synthesis and their surface functionalization hold a crucial position in the design and fabrication of functional materials for a variety of biomedical applications. Non-uniform nanoparticles with poor crystallinity, prepared by conventional methods, have only limited value in biological areas. Large scale synthesis methods that are able to produce high quality, mono-dispersed iron oxide nanoparticles using low cost and environment friendly chemicals are highly desirable. Following synthesis, appropriate surface functionalization is necessary to direct the dispersibility of nanoparticles in aqueous solution in order to provide them with acceptable colloidal stability against the ion strength and many biomolecules …

Trouble Every Day, Nina E. Schwanse

LSU New Orleans Theses and Dissertations

My interests lie in the intersection of the public and private, the corporate and personal, especially with regard to self-representation within cultural power structures. Utilizing video and web technologies, performance, and painting, I create imagined realms of fantasy, desire, obsession, and anxiety. Operating within, but not bound by, feminist discourse, my work explores the vehicles and effects by which both analog and digital technologies influence the relationship between the self and the object of desire (whether physical or virtual, interior or exterior to the body) and have produced both progressive and regressive offspring. By performing the role of both producer …

Ii-Vi Core-Shell Nanowires: Synthesis, Characterizations And Photovoltaic Applications, Kai Wang

LSU New Orleans Theses and Dissertations

The emergence of semiconducting nanowires as the new building blocks for photovoltaic (PV) devices has drawn considerable attention because of the great potential of achieving high efficiency and low cost. In special, nanowires with a coaxial structure, namely, core-shell structures have demonstrated significant advantages over other device configurations in terms of radial charge collection and cost reduction. In this dissertation, several core-shell nanowire structures, including ZnO/ZnSe, ZnO/ZnS, and CdSe/ZnTe, have been synthesized and the photovoltaic devices processed from a ZnO/ZnS core-shell nanowire array and a single CdSe/ZnTe core-shell nanowire have been demonstrated.

By combining the chemical vapor deposition and pulsed …

Municipal Wastewater Disinfection With Electromagnetic Waves Using Escherichia Coli Concentration As Measurement Of Quantification, Lauren M. Cagle

LSU New Orleans Theses and Dissertations

Wastewater treatment is essential to protecting the environment and human welfare. Although chlorination is widely used, the environmental and health concerns associated with chlorine are growing. Treatment facilities are implementing alternative technologies, though the cost and efficiency associated with these practices leave much room in the wastewater field for innovation.

Hydropath Technologies Limited introduced a piece of equipment that uses the properties of a transformer to pass an alternating electric current through the pipe and into the contents of the channel. Hydroflow claims that the charged microorganisms react with the oppositely charged water molecule to force osmosis and kill the …

Completely Recursive Least Squares And Its Applications, Xiaomeng Bian

LSU New Orleans Theses and Dissertations

The matrix-inversion-lemma based recursive least squares (RLS) approach is of a recursive form and free of matrix inversion, and has excellent performance regarding computation and memory in solving the classic least-squares (LS) problem. It is important to generalize RLS for generalized LS (GLS) problem. It is also of value to develop an efficient initialization for any RLS algorithm.

In Chapter 2, we develop a unified RLS procedure to solve the unconstrained/linear-equality (LE) constrained GLS. We also show that the LE constraint is in essence a set of special error-free observations and further consider the GLS with implicit LE constraint in …

The Role Of Community Land Trusts In Preserving And Creating Commercial Assets: A Dual Cae Study Of Rondo Clt In St. Paul, Minnesota And Crescent City Clt In New Orleans, Louisiana, Elizabeth Sorce

LSU New Orleans Theses and Dissertations

As the community land trust (CLT) movement in the United States approaches its 50^th anniversary, CLT members, practitioners and researchers are exploring and pushing the boundaries of the model. CLTs offer an alternative model of land use tenure that permanently removes properties from the speculative market for the ongoing common good of the community. Most frequently associated with the provision of affordable housing in strong real estate markets, several CLTs across the country are now expanding into the commercial realm. This thesis compares the incipient commercial development efforts underway in St. Paul, Minnesota and New Orleans, Louisiana in order …

Returning To Post-Katrina New Orleans: Exploring The Processes, Barriers, And Decision-Making Of African Americans, Kim Mosby

LSU New Orleans Theses and Dissertations

This qualitative case study explores the post-Katrina experiences of African Americans in Houston and in New Orleans. When the levees failed, residents from New Orleans were scattered across the country. Houston housed the largest population of displaced low-income African Americans from New Orleans. As the rebuilding process began, housing, employment, education, and healthcare policies in New Orleans changed. These institutional changes employed urban revitalization and poverty removal strategies adapted to disaster recovery. This study differs from previous research by examining these changes with an intersectional approach. It explores how African Americans frame obstacles as they attempt to return to a …

“Bury Your Head Between My Knees And Seek Pardon”: Gender, Sexuality, And National Conflict In John Okada’S No-No Boy, Patricia A. Thomas

LSU New Orleans Theses and Dissertations

In “‘Bury Your Head Between My Knees and Seek Pardon’: Gender, Sexuality, and National Conflict in John Okada’s 1957 novel, No-No Boy,” I analyze the ways in which the complexities of gendered sexuality expressed by protagonist Ichiro Yamada intersect with post-World War II and Internment-era national identifications for American nisei. I demonstrate that this apparent story of one man’s pursuit to resolve his conflict over national identity is, in reality, a tour de force of literary subversion that not only destabilizes the subterfuge that surrounded internment but also—in its deliberate failure to resolve questions of national conflict on the …

Understanding Land Use Grain: An Evaluation Of Meaning And Measurement, Benjamin N. Williams

LSU New Orleans Theses and Dissertations

Land use grain is a commonly-used measure of the mixture of land uses in the urban environment in transportation planning and public health, but there is no standard measurement practice in place. This thesis examines the meaning and common measurements of land use grain in these subfields. The entropy-based equation, the jobs-to-housing ratio, and the Herfindahl-Hirschman Index (HHI) are among the most common measures of land use grain, but results from these metrics differ depending upon how researchers choose a sample area and upon how land use categories are defined. All three metrics are performed, in a single context with …

Birds In Residential Metropolitan New Orleans Neighborhoods And Their Relationships To The Batture And Yard Vegetation, Ruth A. Guymon

LSU New Orleans Theses and Dissertations

Metropolitan New Orleans Neighborhoods were surveyed in order to determine how bird populations responded to distance from the batture, percent canopy cover, stem counts, and understory vegetation. Surveys were conducted in the spring and summer of 2010. It was found that batture birds, urban birds, and pooled birds all had greater species richness and abundance in the spring in areas with more canopy cover, higher stem counts, more understory vegetation, and distances closer to the batture. In the summer, batture birds had greater richness and abundance in areas with more canopy cover, higher stem counts, and more understory cover. This …

Electronic Transport In Thermoelectric Bismuth Telluride, Westly Nolting

LSU New Orleans Theses and Dissertations

An experimental investigation of the electronic transport properties of bismuth telluride nanocomposite materials is presented. The primary transport measurements are electrical conductivity, Seebeck coefficient and Hall effect. An experimental apparatus for measuring Hall effect and electrical conductivity was designed, constructed and tested. Seebeck coefficient measurements were performed on a commercial instrument. The Hall effect and Seebeck coefficient measurements are two of the most important tools for characterizing thermoelectric materials and are widely used in the semiconductor industry for determining carrier types, carrier concentration and mobility. Further, these transport parameters are used to determine the thermal to electrical conversion efficiency of …

Comparing Newly Built Wetlands In The Atchafalaya Bay, Louisiana And Sacramento-San Joaquin Delta, California, Lindsay L. Dunaj

LSU New Orleans Theses and Dissertations

This research investigated patterns in elevation change in newly built wetlands in the Atchafalaya delta, and newly restored wetlands in the Sacramento-San Joaquin River delta. RSETs were used to measure small changes in elevation, and soil cores were processed to examine mineral and organic contributions.

Elevation change was highly variable, responding to influences from water level, river discharge, storms and vegetation. Mineral matter consistently added more to the marsh soil through volumetric and gravimetric contributions. Organic contributions were not significantly different across sites, suggesting the type of emergent vegetation at a site may not be the most important factor.

RNA-seq experiments generate hundreds of millions of short reads for each DNA/RNA sample. There are many existing bioinformatics tools developed for the analysis and visualization of this data, but very large studies present computational and organizational challenges that are difficult to overcome manually. We designed a comprehensive pipeline for the analysis of RNA sequencing which leverages many existing tools and parallel computing technology to facilitate the analysis of extremely large studies. RNA CoMPASS provides a web-based graphical user interface and …

Synthesis And Characterization Of Sugar Derivatives As Functional Gelators, Michael J. St Martin

LSU New Orleans Theses and Dissertations

Systems formed by the supramolecular assemblages of organic molecules known as organogelators and hydrogelators are currently, and only recently, a subject of great attention and promise. In this context, low molecular weight gelators (LMWGs) are of particular interest because they provide a bottom-up approach to the formation of supramolecular architectures through self-assembly. Gelator molecules do so via the initial formation of a one-dimensional array of individual molecules bound non-covalently through forces such as: hydrogen bonds, electrostatic forces, Van der Waals interactions, and other weak forces such as π-π interactions. These interactions then lead to secondary structure formation through a similar …

Transforming Sustainability Thru Adaptive Co-Management: A Critique Of Louisiana’S Coastal Master Plan, Melanie G. Sand

LSU New Orleans Theses and Dissertations

To achieve true sustainability, planners must balance the interests of environmental protection, economic development, and social equity. In a critically changing, complex ecosystem such as Louisiana’s coast, challenges to achieve the perfect equilibrium are further compounded. Following the logic of emerging adaptive co-management literature, the planning framework for Louisiana’s Coastal Master Plan could be transformed into a more collaborative, democratic process. Adaptive co-management is a regime which provides power to local citizens, often in possession of invaluable traditional ecological knowledge. In general, it focuses on constant learning and collaboration. Through power-sharing and participatory action, we embrace science, but step back …

Come As You Are, As I Want You To Be: Grunge/Riot Grrrl Pedagogy And Identity Construction In The Second Year Writing Program, Rory J. Callais

LSU New Orleans Theses and Dissertations

A look at how artists in the grunge and Riot Grrrl movements constructed public identities that typically appealed to the economic, cultural, and social conditions of the early 1990s. These public personas -- perceived as “honest” -- were defined by negotiation with mainstream culture, the notion of the “confessional,” and gender construction. By examining how these identities were constructed, composition students can see how cultural influences mediate their own identity construction. A “grunge/Riot Grrrl” pedagogy is proposed that encourages students to look at how identities are constructed across a multimedia landscape, reflecting the way grunge and Riot Grrrl artists built …
