Measuring Access To Employment To Guide And Evaluate Public Transit Service Planning In New Orleans, Kevin Harrison

LSU New Orleans Theses and Dissertations

New software and technology is making it easier than ever before for public transportation planners to evaluate how quickly residents can reach jobs and other destinations. Because in the past it was difficult to measure access to opportunities, these concepts remained primarily in the theoretical and academic realms of research. This thesis reviews methods that could be used to evaluate routine bus service improvements and performs a comparative analysis of different methods in the context of New Orleans. There are many different variables in how the analysis could be performed, but this thesis focuses on the role that time of …

Practical Application Of Fast Disk Analysis For Selective Data Acquisition, Sergey Gorbov

LSU New Orleans Theses and Dissertations

Using a forensic imager to produce a copy of the storage is a common practice. Due to the large volumes of the modern disks, the imaging may impose severe time overhead which ultimately delays the investigation process. We proposed automated disk analysis techniques that precisely identify regions on the disk that contain data. We also developed a high performance imager that produces AFFv3 images at rates exceeding 300MB/s. Using multiple disk analysis strategies we can analyze a disk within a few minutes and yet reduce the imaging time of by many hours. Partial AFFv3 images produced by our imager can …

Phylogenetic Relationships And Evolution Of Snakes, Alex Figueroa

LSU New Orleans Theses and Dissertations

Snakes represent an impressive evolutionary radiation of over 3,500 widely-distributed species, categorized into 515 genera, encompassing a diverse range of morphologies and ecologies. This diversity is likely attributable to their distinctive morphology, which has allowed them to populate a wide range of habitat types within most major ecosystems. In my first chapter, I provide the largest-yet estimate of the snake tree of life using maximum likelihood on a supermatrix of 1745 taxa (1652 snake species + 7 outgroup taxa) and 9,523 base pairs from 10 loci (5 nuclear, 5 mitochondrial), including previously unsequenced genera (2) and species (61). I then …

Feats And Failures Of Corporate Credit Risk, Stock Returns, And The Interdependencies Of Sovereign Credit Risk, Uche C. Isiugo

LSU New Orleans Theses and Dissertations

This dissertation comprises two essays; the first of which investigates sovereign credit risk interdependencies, while the second examines the reaction of corporate credit risk to sovereign credit risk events. The first essay titled, Characterizing Sovereign Credit Risk Interdependencies: Evidence from the Credit Default Swap Market, investigates the relationships that exist among disparate sovereign credit default swaps (CDS) and the implications on sovereign creditworthiness. We exploit emerging market sovereign CDS spreads to examine the reaction of sovereign credit risk to changes in country-specific and global financial factors. Utilizing aVAR model fitted with DCC GARCH, we find that comovements of spreads …

Sustainable Ambient Air Quality Monitoring System, Poojitha Aleti

LSU New Orleans Theses and Dissertations

Deterioration of air quality is a growing concern in the world. Air pollution causes serious health problems and also can sometimes result in death. In order to assess air quality, long term and continuous monitoring of pollutant levels in ambient air are needed, such monitoring is often expensive, cumbersome, and resource intensive and so the monitoring programs often fail to succeed.

This research focused on designing an ambient air monitoring system by integrating (1) low-cost sensor with a battery, (2) repurposed materials to fabricate all-weather housing for air monitors, and (3) electronics needed to download the data to an on-site …

3d Post-Stack Seismic Inversion Using Global Optimization Techniques: Gulf Of Mexico Example, Elijah A. Adedeji

LSU New Orleans Theses and Dissertations

Seismic inversion using a global optimization algorithm is a non-linear, model-driven process. It yields an optimal solution of the cost function – reflectivity/acoustic impedance, when prior information is sparse. The inversion result offers detailed interpretations of thin layers, internal stratigraphy, and lateral continuity and connectivity of sand bodies. This study compared two stable and robust global optimization techniques, Simulated Annealing (SA) and Basis Pursuit Inversion (BPI) as applied to post-stack seismic data from the Gulf of Mexico.

Both methods use different routines and constraints to search for the minimum error energy function. Estimation of inversion parameters in SA is rigorous …

Two Essays In Corporate Finance, Youngha Ki

LSU New Orleans Theses and Dissertations

For more than a decade, to reduce the agency problem, various ways have been examined on how to align the interest of manager with shareholders. Evidence and empirical findings are conflicting on the agency problem. Recently, deferred compensation as one incentive compensation draws the attention as a means to incentivize CEOs to make them work for the firm. However, it is still not evident if deferred compensation has effect on aligning CEOs with the firm’s goal possibly due to the issue on data. Therefore, the first essay investigates if deferred compensation has the effect on the agency problem and on …

Habitat Suitability Modeling For The Mississippi Sandhill Crane, Grus Canadensis Pulla, Linda C. Salande

LSU New Orleans Theses and Dissertations

In this study, I modeled the suitability of habitat on the Mississippi Sandhill Crane National Wildlife Refuge for the federally endangered Mississippi Sandhill Crane (Grus Canadensis pulla). Habitat type and suitability changed over time due to seasonality of vegetation and succession in the absence of burning. Cranes used highly suitable habitat more in the non-growing than in the growing season, and may have been more constrained by resource availability during winter months. Cranes used some less-suitable areas including cypress drains, which provide roosting sites, and supplemental food plots. The mismatch between predicted quality and crane use suggests that …

“On The Cusp Of Half-Remembered Prophecies”: Interpreting Prophecy In George R. R. Martin’S A Song Of Ice And Fire, Patrice A. Loar

LSU New Orleans Theses and Dissertations

The prophecies in George R. R. Martin’s A Song of Ice and Fire series are unclear and often appear to have multiple possible fulfillments, or none at all. In addition, some of these prophesied events occur before they are introduced, which further contributes to the lack of clarity in interpreting them. My thesis will discuss the methods by which Martin offers readers clues to a prophecy’s fulfillment and argue that Martin’s use of these imprecise prophecies challenges high fantasy tropes about prophecies.

Coastal Louisiana: Adaptive Capacity In The Face Of Climate Change, Tara Lambeth

LSU New Orleans Theses and Dissertations

Extreme weather events can result in natural disasters, and climate change can cause these weather events to occur more often and with more intensity. Because of social and physical vulnerabilities, climate change and extreme weather often affect coastal communities. As climate change continues to be a factor for many coastal communities, and environmental hazards and vulnerability continue to increase, the need for adaptation may become a reality for many communities. However, very few studies have been done on the effect climate change and mitigation measures implemented in response to climate change have on a community’s adaptive capacity.

Neural Mechanisms Of Action Switching Moderate The Relationship Between Effortful Control And Aggression, Eric L. Rawls

LSU New Orleans Theses and Dissertations

Aggression and violence are social behaviors that exact a significant toll on human societies. Individuals with aggressive tendencies display deficits in effortful control, particularly in affectively charged situations. However, not all individuals with poor effortful control are aggressive. This study uses event-related potentials (ERPs) to decompose the chronology of cognitive functions underlying the link between effortful control and aggression. Specifically, this study investigates which ERPs moderate the effortful control - aggression association. We examined three successive ERP components (P2, N2 and P3) for stimuli that required effortful control. Results indicated that N2 activation, but not P2 or P3 activation, moderated …

Comparing Methods Of Euthanasia And Gill Culture For Hypoxia Research On The Gulf Killifish, Fundulus Grandis, Kristina M. Farragut

LSU New Orleans Theses and Dissertations

Aquatic hypoxia, or low dissolved oxygen, is a growing environmental concern and has detrimental effects on many fishes. Research on fish responses to hypoxia includes whole animal studies as well as organ culture systems. In this thesis, the gulf killifish, Fundulus grandis, was used to determine the interaction between hypoxic exposure and four common euthanasia techniques on selected blood and gill variables and to develop an in vitro gill incubation system. Euthanasia techniques had differential effects on blood and gill, with the common fish anesthetic MS-222 having the greatest effects, but none altered the response to hypoxia. During the …

Surviving In The Land Of Opportunity: Outcomes Of Post-Crisis Urban Redevelopment In The United States, Brianna D. Foster

Engineering Nanoarchitectures From Nanosheets, Nanoscrolls, And Nanoparticles, Taha Rostamzadeh

LSU New Orleans Theses and Dissertations

The ability to encapsulate/insert different kinds of nanoparticles (NPs) in scrolled nanosheets (NSs) may lead to the formation of new nanocomposite materials that yield novel properties. These nanostructures resemble “peapods” that consist of NPs chains (“peas”) located in a hollow space of desired nanoscrolls (“pods”). Depending on different combinations of “peas” and “pods” diverse families of nanopeapods (NPPs) can be synthesized which may exhibit interesting properties not accessible from the individual components. Though there exist various synthetic methods for the formation of NPPs, more development in terms of simplicity, flexibility, and productivity of synthetic approaches are needed so that different …

Exposing The “Shadow Side”: Female-Female Competition In Jane Austen’S Emma, Melissa M. Lyman

LSU New Orleans Theses and Dissertations

Many critics have examined the shifting nature of female friendship in Jane Austen’s Emma from cultural and historical angles. However, a comprehensive scientific analysis of female-female alliance and competition in the novel remains incomplete. The Literary Darwinist approach considers the motivations of fictional characters from an evolutionary perspective, focusing primarily on human cognition and behaviors linked to reproductive success, social control, and survival. While overt physical displays of male competition are conspicuous in the actions of the human species and those of their closest primate relatives, female aggression is often brandished psychologically and indirectly, which makes for a much more …

Spice: A Software Tool For Studying End-User’S Insecure Cyber Behavior And Personality-Traits, Anjila Tamrakar

LSU New Orleans Theses and Dissertations

Insecure cyber behavior of end users may expose their computers to cyber-attack. A first step to improve their cyber behavior is to identify their tendency toward insecure cyber behavior. Unfortunately, not much work has been done in this area. In particular, the relationship between end users cyber behavior and their personality traits is much less explored. This paper presents a comprehensive review of a newly developed, easily configurable, and flexible software SPICE for psychologist and cognitive scientists to study personality traits and insecure cyber behavior of end users. The software utilizes well-established cognitive methods (such as dot-probe) to identify number …

An Alternate Trawling Method: Reduced Bycatch And Benthic Disturbance Achieved With The Wing Trawling System, Geoffrey Udoff

LSU New Orleans Theses and Dissertations

The Wing Trawling System (WTS) was tested as an alternative to traditional shrimp capture methods in the Gulf. Compared to an otter trawl, this trawl was conceived to reduce bycatch, retain shrimp catch, and minimize seafloor disturbance. Through seventy-one paired tows, the WTS was assessed against a standard otter trawl. The WTS was found to reduce bycatch by 63-65% and reduce shrimp catch by 30-35%. Additionally, I measured the depth of the scars produced by both trawls and quantified the turbidity of the plumes behind them. The scars left by the WTS and the otter trawl were between 9.9 …

Unearthing Real Women: Reclaiming Sylvia Plath And Virginia Woolf From Their Suicide Narratives, Jessica Dunn

LSU New Orleans Theses and Dissertations

Virginia Woolf and Sylvia Plath are two well-known women writers of the twentieth century who committed suicide. The narratives created by their deaths have in some instances become as important as the canonical work they produced. In an effort to understand their motivations and struggles, critics and the public alike have sometimes reduced these women to victims of the patriarchy, mental illness, or even themselves.

Beginning with my own discovery of this issue in the legacies of Plath and Woolf combined with my personal dealings with suicide in my family, I recount how I lost these two women as exemplary …

Purification And Characterization Of Antibodies Against Killifish Hif-1Α, Janet Gonzalez-Rosario

LSU New Orleans Theses and Dissertations

Many fish face low oxygen concentrations (hypoxia) in their natural environments, and they respond to hypoxia through a variety of behavioral, physiological, and cellular mechanisms. Some of these responses involve changes in gene expression. In mammals, the hypoxia inducible factor (HIF) family of transcription factors are the “master regulators” of gene expression during hypoxia, but the study of HIF in fish has been hampered by the lack of reagents to detect this protein in non-mammalian vertebrates. The goals of this thesis are to affinity purify antibodies against HIF from the killifish Fundulus heteroclitus and use them to recover and quantify …
