Septotemporal Variation In Theta Rhythm Dynamics: Effects Of Speed And Habituation, James Hinman

Master's Theses

Theta (6-12 Hz) field potentials and the synchronization (coherence) of these potentials present neural network indices of hippocampal physiology. Theta signals within the hippocampal formation may reflect alterations in sensorimotor integration, the flow of sensory input and/or distinct cognitive operations. While the power and coherence of theta signals vary across lamina within the septal hippocampus, limited information is available about variation in these indices across the septotemporal (long) or areal axis. The present study examined the relationship of locomotor speed to theta indices at CA1 and DG sites across the septotemporal axis as well as in the entorhinal cortex. Our …

Reconstituting Land-Use Federalism To Address Transitory And Perpetual Disasters: The Bimodal Federalism Framework, Blake Hudson

BYU Law Review

Scholars analyzing the intersection of federalism and disaster law and policy have primarily focused on the difficulties federalism poses for interjurisdictional coordination of disaster response. Though scholars have highlighted that rising disaster risks and costs are associated with “land-use planning that exacerbates, rather than mitigates, disaster risk,” a more holistic analysis of land-use-related disaster law and policy is needed. This Article provides a more comprehensive framework within which to analyze prospective mitigation or prevention of disaster risk and costs through a rebalancing—or reconstituting—of the respective roles of the federal and state governments in land-use planning. The federal government does not …

Role Of Pseudomonas Produced Hydrogen Cyanide In Biological Control Of Plant-Parasitic Nematodes, Haytham Aly

Dissertations

Plant-parasitic nematodes are among the most devastating pests world-wide, causing extensive damage to important agriculture crops. The management of nematodes is challenging. Current methods used for nematode control rely mostly on using chemical nematicides and naturally resistant plants. Because of serious health and environmental problems associated with chemical control and over use of resistant plants resulting in resistant breaking strains of nematodes, alternative nematode-control methods are needed. Several potential nematode-biocontrol agents, including bacteria and fungi, have been studied for their antagonistic effect toward plant-parasitic nematodes. However, a concise picture about the biological agent’s mechanisms used to antagonize nematodes remains elusive. …

Positive Solutions For Rural Solid Waste Management, Jessica L. Meyer

Rural Development

Rural solid waste management is and will continue to be one of the leading environmental problems facing the twenty-first century. As the global south, under developed, and developing countries progress, proper solid waste management must be a priority to keep humans and ecosystems healthy and safe. This study provides an overview of the Republic of Macedonia's solid waste management and the discoveries of public and environmental health risks as a result of unsanitary landfills and illegal dumping. These problems are caused by low enforcement of environmental laws, minimal governmental and public support, as well as lack of funding and infrastructure. …

Reproductive Ecology And Morphometric Subspecies Comparisons Of Dunlin (Calidris Alpina), An Arctic Shorebird, Heather River Gates

Biological Sciences

The Arctic region provides globally important breeding and migratory habitat for abundant wildlife populations including migratory shorebirds. Due to their remote breeding locations, basic information on breeding ecology, annual productivity, and factors that regulate their populations are poorly studied. Wildlife biologists managing migratory bird populations require detailed information on avian breeding biology, in addition to information on migration ecology including connectivity of migratory stopover and wintering locations. To address information gaps in fecundity, I conducted an experimental study investigating the renesting ecology of Dunlin (Calidris alpina arcticola) by removing clutches at two stages of incubation and by following adults marked …

Terrestrial Invertebrate Prey For Juvenile Chinook Salmon: Abundance And Environmental Controls In An Interior Alaska River, Laura Gutierrez

Biological Sciences

Terrestrial prey subsidies can be a key food source for stream fish, but their importance and environmental controls on their abundance have not been widely documented in high latitude ecosystems. This study investigated terrestrial invertebrate prey availability and predation by age-0+ juvenile chinook salmon (Oncorhynchus tshawytscha), overlap between terrestrial infall and drift to diet, and the relationship between diet to stream temperature and discharge in the Chena River, Interior Alaska. Terrestrial infall, drift, and juvenile chinook diet varied widely through the summers (May-September) of 2008 and 2009. Drift was comprised of 33% terrestrial and 67% aquatic invertebrate mass, while juvenile …

This thesis research involved a reinvestigation of the Teklanika West (HEA-001) archaeological site, central Alaska. It focused on understanding and expanding upon the site formation processes, dating, and characterizing cultural components at the site. Analyses were designed to address the preceding research purposes, while inter-relating research objectives. Twelve and a quarter square meters were excavated within five blocks located across the site. These excavation blocks yielded dateable materials in clear association with chipped-stone technology. Both environmental and cultural data obtained at the site have produced a more complex understanding of the site and surrounding landscape. Multiple components ranging in age …

Considering Predation By Humpback Whales In The Mystery Of The Failed Recovery Of Pacific Herring In Prince William Sound, Alaska, Suzanne F. Teerlink

Fisheries

In Prince William Sound (PWS) in the early 1990s, biomass of an important forage species, Pacific herring (Clupea pallasii), crashed and has since failed to recover. This thesis explores the role that predation by humpback whales (Megaptera novaeangliae) may have in limiting this recovery. This was done by modeling the historic (1980-2009) relationship between these two species using existing data. Mark-recapture estimates of abundance were combined to form the first time series of humpback whale abundance for this area. This time series was then integrated into the age-structured assessment model used by Alaska Department of Fish and Game to manage …

The Use Of Aerial Imagery To Map In-Stream Physical Habitat Related To Summer Distribution Of Juvenile Salmonids In A Southcentral Alaskan Stream, Jeff Perschbacher

Fisheries

Airborne remote sensing (3-band multispectral imagery) was used to assess in-stream physical habitat related to summer distributions of juvenile salmonids in a Southcentral Alaskan stream. The objectives of this study were to test the accuracy of using remote sensing spectral and spatial classification techniques to map in-stream physical habitat, and test hypotheses of spatial segregation of ranked densities of juvenile chinook salmon Oncorhynchus tschwytscha, coho salmon O. kisutch, and rainbow trout O. mykiss, related to stream order and drainage. To relate habitat measured with remote sensing to fish densities, a supervised classification technique based on spectral signature was used to …

Refined Liquid Smoke: A Potential Antilisterial Supplement To Cold-Smoked Sockeye Salmon (Oncorhynchus Nerka), Naim Montazeri Djouybari

Fisheries

Listeria monocytogenes, the causative agent of listeriosis can contaminate cold smoked salmon (CSS) and make it a high-risk ready-to-eat food product. Due to the lack of a critical control point in the cold-smoking process, a post-process elimination is essential to ensure product safety. The goal of this project was to improve safety of vacuum-packaged CSS supplemented with commercially refined liquid smoke (LS). Gas chromatography-mass spectrometric analysis showed the LS were high in carbonyl containing compounds and low in phenol derivatives. The LS (AM-10 and AM-3) producing the greatest inhibition against L. innocua in a paper disk diffusion assay were applied …

Characteristics Of The Sulukna River Spawning Population Of Inconnu, Yukon River Drainage, Alaska, David Andrews Esse

Fisheries

Inconnu Stenodus leucichthys are large migratory whitefish harvested in subsistence and sport fisheries in Alaska. Research on the Sulukna River spawning population of inconnu was conducted in September and early October from 2007 to 2009. Samples were collected to verify maturity and spawning readiness, and to determine age distributions of mature males and females. Spawning abundance was estimated and post-spawning migration timing was identified. Otoliths were analyzed optically to determine age and chemically to determine amphidromy. Maturity sampling indicated that all sampled fish were in spawning condition or had recently spawned. Abundance estimates were 2,079 and 3,531 inconnu in 2008 …

Animal Companionship And Identity Construction In The Middle English "Ywain And Gawain", Robert E. Byers

English

As a relatively recent field within literary cultural studies, "animal studies" has the potential to ask sophisticated new questions about the central and privileged place of the humanist "cogito." Through an examination of the human-animal companionship found in the Middle English romance "Ywain and Gawain", this thesis aims to contribute to the project of animal studies by tracing how questions about humanity and animality both construct and deconstruct a subject's identity. In the poem, Ywain, a knight in Arthur's court, is exiled from society and befriends a lion, who travels and fights alongside him. The dynamics of their bond highlight …

Ecosystem Management And Its Application At The Local Level: Apnep, Cama And Local Land Use Planning In North Carolina, Traci L. Birch

LSU New Orleans Theses and Dissertations

A fundamental purpose of state-mandated growth management has been to infuse regional environmental concerns into local land use planning. Similarly, collaborative ecosystem planning efforts have attempted to encourage local communities to participate in regional planning efforts, and to adopt regional environmental goals and objectives into local land use plans. This paper presents results from a study of state-mandated local planning and collaborative regional planning, addressing in particular local ability to adopt and implement ecosystem planning initiatives for development management.

I found that a state mandate not only achieves plans from communities that would not otherwise plan, but also the plans …

Data Exploration Interface For Digital Forensics, Varun Dontula

LSU New Orleans Theses and Dissertations

The fast capacity growth of cheap storage devices presents an ever-growing problem of scale for digital forensic investigations. One aspect of scale problem in the forensic process is the need for new approaches to visually presenting and analyzing large amounts of data. Current generation of tools universally employ three basic GUI components—trees, tables, and viewers—to present all relevant information. This approach is not scalable as increasing the size of the input data leads to a proportional increase in the amount of data presented to the analyst.

We present an alternative approach, which leverages data visualization techniques to provide a more …

Analysis Of Biomass/Coal Co-Gasification For Integrated Gasification Combined Cycle (Igcc) Systems With Carbon Capture, Henry A. Long Iii

LSU New Orleans Theses and Dissertations

In recent years, Integrated Gasification Combined Cycle Technology (IGCC) has become more common in clean coal power operations with carbon capture and sequestration (CCS). Great efforts have been spent on investigating ways to improve the efficiency, reduce costs, and further reduce greenhouse gas emissions. This study focuses on investigating two approaches to achieve these goals. First, replace the subcritical Rankine steam cycle with a supercritical steam cycle. Second, add different amounts of biomass as feedstock to reduce emissions. Finally, implement several types of CCS, including sweet- and sour-shift pre-combustion and post-combustion.

Using the software, Thermoflow®, this study shows that utilizing …

Milneburg, New Orleans: An Anthropological History Of A Troubled Neighborhood, Betty A. Smallwood

LSU New Orleans Theses and Dissertations

For nearly 200 years, there has been a neighborhood in New Orleans, Louisiana named Milneburg, which has been constantly reimagined by its inhabitants and others. From its inception as a port of entry in 1832 until the 2011, it has been called a world-class resort, the poor-man's Riviera, a seedy red-light district, a cradle of jazz, a village, a swath of suburbia and a neighborhood. It has been destroyed eight times due to storms, fires, and civic or governmental neglect. Each time its residents have rebuilt it. In its last iteration as a post-Katrina neighborhood, the residents reestablished the Milneburg …

N'Awlins Po Boy, Warren J. Graffeo

LSU New Orleans Theses and Dissertations

Abstract

N’Awlins Po Boy draws heavily on the author’s memories and recollections of growing up in the New Orleans of the 1940s and 1950s, but it is a work of fiction. Although the settings and scenes are rendered as accurately as memory allows, the circumstances, situations and people are entirely fictional. During the immediate post-WWII decade, the city went through a rapid series of changes, some calm and nearly unnoticed, others turbulent and upsetting to the natural order that had prevailed for more than two centuries. This is an account of those changes as they might have been seen through …

Factors That Contribute To Susceptibility Of The Placebo/Nocebo Effect In Experimentally Induced Ischemic Arm Pain, Steve T. Brewer

LSU New Orleans Theses and Dissertations

Placebo’s (positive expectancies producing positive outcomes) and nocebo’s (negative expectancies producing negative outcomes) are real and measurable effects. Real as these effects may be, predicting individuals that may be susceptible to placebo/nocebo effects has been inconsistent. The present study examined whether measures designed to assess somatization (MSPQ), catastrophizing (PCS) and childhood trauma (CTQ) would predict placebo and nocebo membership. In addition, measures designed to assess anxiety (ASI) anxiety about pain (PASS) and depression (BDI) were evaluated to determine whether anxiety or depression mediates responsiveness. The Hargreaves Thermal Withdrawal test and the submaximal effort tourniquet technique were employed as pain vehicles …

Snap, Nathan Feuerberg

LSU New Orleans Theses and Dissertations

The term ‘snap’ can be defined as breaking under tension as well as a sudden sharp noise. Both definitions lend themselves to the content of this short story collection and its theme of self-realization (the awakening from an illusionary self-identity or ego).

Snap is a progression of stories that revolves around waking up. Novels such as Ralph Ellison’s Invisible Man, Margaret Atwood’s Surfacing, and Paul Auster’s The New York Trilogy have all examined the issue of finding identity through a breaking of the protagonist. In each case, the protagonists come to a point where they completely separate themselves …
