A Systematic Investigation Into Relationships Within Mexican Pocket Gophers, Thomomys Umbrinus (Rodentia Geomyidae), Amber Gates

LSU Master's Theses

In the genus Thomomys, external phenotypic differences account for much of the variation among currently named species. Allozyme and mitochondrial studies of the Mexican species, T. umbrinus, have shown strong discordance between genetically defined clades and current species taxonomy. In this study, I analyzed mitochondrial and nuclear DNA sequences, chomosomes, and morphological characters, and used ecological niche modeling to investigate the phylogenetic status of a phenotypically divergent subspecies of T. umbrinus, T. u. atrovarius. Although quantitative morphometrics provided little discrimination among groups within T. umbrinus, the molecular data indicated that there are three allopatric clades. The Pacific coastal clade (T. …

Assessing Linkages Between Petroleum Platforms And Pelagic Fishes Using Telemetry With Emphasis On Blue Runner (Caranx Crysos), Harmon Brown

LSU Doctoral Dissertations

Petroleum platforms number greater than 4,200 in the Gulf of Mexico and Caranx crysos (blue runner) is one of the most abundant fish species around these platforms. Forty-six blue runner were tagged with acoustical transmitters in August 2005, though the study was terminated prematurely due to the impending arrival of Hurricane Katrina. Nineteen blue runner were tagged in September 2006 and tracked for up to two months. Blue runner exhibited limited site fidelity around the platforms in 2005. The home range of twenty-three blue runner was calculated in 2005. A significant difference was found between the fork length of the …

Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans

LSU Master's Theses

Considerable research has been conducted comparing the effect of continuous and some form of rotational stocking method on animal and forage performance, but most research utilizes put-and-take stocking rates. The purpose of this research was to determine the effect of 12-paddock rotational stocking method (ROT) or continuous stocking method (CONT) of winter wheat (Triticum aestivum) and annual ryegrass (Lolium multiflorum) pastures on beef heifer and forage performance while maintaining a continuous stocking rate of 3.7 heifers/ha. Two experiments were conducted and analyzed separately due to confounding year and location. Heifer ADG and WG/ha tended to be increased by ROT compared …

Reductio Ad Hitlerum: Trumping The Judicial Nazi Card, Gabriel H. Teninbaum

Suffolk University Law School Faculty Works

Hitler was a vegetarian, as was Gandhi. Therefore, Gandhi, like Hitler, was evil.

The absurdity of the above statement will be apparent to most readers. Indeed, the ability to understand why these premises do not lead to the conclusion following them is fundamental to being able to understand or perform legal analysis. Nonetheless, judicial opinions commonly include arguments that compare people and institutions with honorable intentions and authority derived from legitimate sources to Hitler, other Nazis or Nazism. For example, in considering whether a Miami police department acted lawfully when it randomly boarded buses and asked passengers for permission to …

The Relationship Between Preexisting Gastroesophageal Reflux Disease In Lung Transplant Recipients And The Development Of Post-Transplant Bronciolitis Obliterans, Heidy Abuan David-Robinson

UNF Graduate Theses and Dissertations

Lung transplant is a treatment modality for patients with end stage lung disease. Bronchiolitis obliterans syndrome (BOS) is the number one cause of morbidity and mortality in patients the first year after lung transplant. There are many risk factors which have been identified to increase the risk of BOS including acute rejection, lymphocytic bronchitis, medication non-compliance, bacterial or viral infections, older donor age, extended ischemic time, donor antigen-specific reactivity, human leukocyte antigen (HLA) mismatch, underlying disease and gastroesophageal reflux disease (GERD).

Advanced practice nurses can help in the primary prevention of BOS through the assessment and treatment of pre-transplant patients …

The Effect Of Electronic Feedback On Anesthesia Providers' Timely Preoperative Antibiotic Administration, Jonathan Pabalate

UNF Graduate Theses and Dissertations

The growing presence of electronic anesthesia record keeping and perioperative informatics systems is contributing to a database of valuable information that can significantly improve patient care and patient outcomes. Efforts such as the National Surgical Quality Improvement Project and the Surgical Care Improvement Project have analyzed quality measures that directly correlate to patient outcomes. Several of these quality indicators are influenced by the performance of anesthesia providers’ activities in the perioperative period. These programs promote timely administration of preoperative antibiotics. One of their guidelines states that preoperative antibiotic should be given within an hour prior to surgical incision. Surgical site …

Potential For Range Expansion Of The Invasive Green Mussel, Perna Viridis, In The Southeastern United States, Alyson Goodwin Urian

UNF Graduate Theses and Dissertations

Cold temperatures are thought to be among the most important determining factors of geographic distribution for tropical and sub-tropical marine invertebrates. The Asian green mussel, Perna viridis, has been introduced into coastal waters of Florida where its current distribution is hypothesized to be limited by low temperatures during winter. Lethal and sublethal effects (heat shock protein/ Hsp70 expression) of cold water and air temperatures were analyzed in two size classes of P. viridis from Florida in an effort to determine the effects of current and forecasted temperatures on the potential for range expansion. Mussels were exposed to water temperatures …

Quantum Algorithm For Bose-Einstein Condensate Quantum Fluid Dynamics: Twisting Of Filamentary Vortex Solitons Demarcated By Fast Poincare Recursion, Jeffrey Yepez, George Vahala, Linda L. Vahala

Electrical & Computer Engineering Faculty Publications

The dynamics of vortex solitons is studied in a BEC superfluid. A quantum lattice-gas algorithm (measurementbased quantum computation) is employed to examine the dynamical behavior vortex soliton solutions of the Gross-Pitaevskii equation (ø⁴ interaction nonlinear Schroedinger equation). Quantum turbulence is studied in large grid numerical simulations: Kolmogorov spectrum associated with a Richardson energy cascade occurs on large flow scales. At intermediate scales, a new k^-6 power law emerges, due to vortex filamentary reconnections associated with Kelvin wave instabilities (vortex twisting) coupling to sound modes and the exchange of intermediate vortex rings. Finally, at very small spatial scales a …

Bottom Boundary Layer Physics And Sediment Transport Along A Transgressive Sand Body, Ship Shoal, South-Central Louisiana: Implications For Fluvial Sediments And Winter Storms, Daijiro Kobashi

LSU Doctoral Dissertations

Ship Shoal, a shore-parallel sand body, was recently recognized as having a unique physical and biological environment and also as a potential sand resource for coastal restoration in coastal Louisiana. Little is known regarding such dynamics, in concert with fluvial sediments and winter storms, influenced in unique ecosystems, and likely in future potential sand mining. This dissertation addresses such the morphodynamics and sedimentary processes and their implications for the mining from the shoal using field measurements and numerical modeling studies. During the winter-spring season, fluvial sediment plumes shifted from the prevailing west to southeast during the post-frontal phases, resulted in …

Multiple Dataset Visualization (Mdv) Framework For Scalar Volume Data, Gaurav Khanduja

LSU Doctoral Dissertations

Many applications require comparative analysis of multiple datasets representing different samples, conditions, time instants, or views in order to develop a better understanding of the scientific problem/system under consideration. One effective approach for such analysis is visualization of the data. In this PhD thesis, we propose an innovative multiple dataset visualization (MDV) approach in which two or more datasets of a given type are rendered concurrently in the same visualization. MDV is an important concept for the cases where it is not possible to make an inference based on one dataset, and comparisons between many datasets are required to reveal …

Nutrition And Eating Habits In Adolescent Television Programs: A Content Analysis Of Food And Beverage Consumption On Popular Teen Television, Carly Nicole Dickson

LSU Master's Theses

Media research often argues that viewing certain media can significantly increase the likelihood someone will develop an eating disorder or become obese. This study uses social cognitive and drama theory to discuss how adolescents may learn nutrition information and eating habits by watching television programs. Since adolescence is when people form eating habits, this exploratory study will analyze the nutrition content in three top teen television shows. This quantitative content analysis found that the characters in teen television primarily have a healthy body size but consume unhealthy items. This may be sending a message to adolescents that unhealthy nutrition maintains …

Comorbid Psychopathology In Individuals With Autism Spectrum Disorders And Intellectual Disabilities, Santino Vincent Lovullo

LSU Master's Theses

While there has been an abundance of research investigating Autism Spectrum Disorders (ASD) in children, very little emphasis has been placed on ASD in adults, especially in regards to comorbid psychopathology. This is of great concern considering that ASD often co-occurs with intellectual disability (ID), and that both may serve as risk factors for additional psychopathology. While instruments exist that measure comorbid psychopathology in adults with ID, these scales are not targeted to the unique expression of comorbidity in adults with ID and ASD. The Autism Spectrum Disorders-Comorbidity for Adults (ASD-CA) was devised for this reason. This paper begins with …

Can Overeating Induce A Conditioned Taste Avoidance In Previously Restricted Rats?, Amanda Louise Hertel

Theses and Dissertations (Comprehensive)

While feeding is rewarding, the feeling of satiation has been theorized to be aversive under certain conditions. Using a food-restriction model of overeating developed in our laboratory the results presented here suggest that overeating, and the resulting experience of satiation, is capable of supporting a conditioned taste avoidance.

Rats had either ad lib (n=8) or restricted (n=24) food access (receiving 50% of the food eaten by ad lib fed rats) for 8 days. All rats were then given 24 hr access to a 0.1% saccharin solution, and two groups of food-restricted rats were given access to either 100% of the …

Population Density, Circulating Testosterone And Dawn Chorus Behaviour In White-Throated Sparrows (Zonotrichia Albicollis), Simon Richard Hall

Theses and Dissertations (Comprehensive)

An integrative approach to biological research has facilitated the study not only of specific phenomena, but of the connections between these phenomena. A particularly striking example is that of the relationships between testosterone, social behavior, and social context. Increased levels of testosterone increase the frequency of aggressive behaviors and reduce the quality of parental care in many songbird species, and these changes in behavior can affect the surrounding social environment. Different social contexts, population density as a readily studied example, affect the cues that control the release of testosterone into the bloodstream. The distinct tan-stripe and white-stripe phenotypic morphs of …

Mitigating Risk For Anxiety Among Preschool-Age Children Living In Poverty: Evaluating The Impact Of Adult-Provided Social Support On Autonomic Stress Reactivity, Brian Cory Wolff

Electronic Theses and Dissertations

Poverty increases children's exposure to stress, elevating their risk for developing patterns of heightened sympathetic and parasympathetic stress reactivity. Repeated patterns of high sympathetic activation and parasympathetic withdrawal place children at risk for anxiety disorders. This study evaluated whether providing social support to preschool-age children during mildly stressful situations helps reduce reactivity, and whether this effect partly depends on children's previously assessed baseline reactivity patterns. The Biological Sensitivity to Context (BSC) theory proposes that highly reactive children may be more sensitive than less reactive children to all environmental influences, including social support. In contrast, conventional physiological reactivity (CPR) theory contends …

Phantoms Of Old Forms: The Gothic Mode In The Dramatic Verse Of Tennyson And Browning, Michael E. Ackerman

Theses and Dissertations (Comprehensive)

My dissertation, “Phantoms of Old Forms: The Gothic Mode in the Dramatic Verse of Tennyson and Browning” situates Alfred Lord Tennyson and Robert Browning within a lineage of writers who experimented with the Gothic mode in dramatic and verse forms. This study is, in the first instance, an experiment in applying a specific strain of Gothic critical theory, one that addresses issues of gender, to canonical literary materials not ordinarily approached in that light. Definitions of the Gothic are notoriously elusive, and this project is not an assertion that the Gothic is always, in all of its manifestations, about gender. …

Constructed Identity, Subjective Identity And Inter-Subjective Transformation: An Exploration By Way Of Motherhood And Canadian Maternity Benefits, Patricia Van Katwyk

Theses and Dissertations (Comprehensive)

When identity is conceptualized as a fluid and ongoing process that is mutually influenced by subjective and constructed experience, an interplay can occur that engenders and signifies collective life. With an acknowledgement of motherhood as a politically and emotionally charged identity experience, and asserting the capacity of social policy to sustain a constructed ideology, this paper explores a conversation that occurred between 28 mothers in Canada. The site of this conversation was an on-line journal (blog). Using a participatory narrative action method of research, the mothers participated as co-researchers, conducting a narrative analysis of one another’s narratives and a policy …

Toward A More Holistic Approach To The Conservation Management Of Southern Ontario’S Small Protected Areas, Wilfred Gregory Tschirhart

Theses and Dissertations (Comprehensive)

Within Southern Ontario’s highly fragmented greater natural ecosystem, there remain numerous relatively small scattered areas which bear at least some resemblance to their former pre-European/Canadian settlement natural ecosystem. In their present state they serve as reservoirs of their particular ecoregion’s indigenous plant and animal species. In proportion to their limited spatial areas, degree of isolation, existing ecological integrity, and long-term ecological carrying capacity they are stores of natural capital, which is beneficial to both nature and society. They co-exist with Southern Ontario’s well developed socioeconomic/cultural system, on whose stewardship their long-term integrity is becoming increasingly dependent, which creates increased environmental …

Responding To Change In A Northern Aboriginal Community (Fort Resolution, Nwt, Canada): Linking Social And Ecological Perspectives, Sonia Darienne Wesche

Theses and Dissertations (Comprehensive)

Human and environmental systems in the circumpolar north are particularly affected by the Earth’s changing climate, thus acting as a bellwether for other parts of the globe. Rural indigenous communities are most visibly impacted due to their close relationship with the land. These challenges are compounded by socio-economic transformations typical of peripheral communities within a larger, centrally governed system.

This dissertation links a community-based study of environmental change in Fort Resolution, Northwest Territories, Canada to evolving adaptation science. The study was prompted by local concern about changing environmental conditions caused by climatic, hydrological and resource development drivers. Its collaborative research …

S. Barnett, H. C. Martin, J. H. Seagraves, M. W. Matthews, R. Winterringer, C. Osborne, Alan D. Christian, N. J. Wentz

Journal of the Arkansas Academy of Science

We analyzed stream inventories, phylogeographic studies, community and population estimates, life history and reproductive biology research, and suitable habitat investigations conducted from 1997-2008, as well as the Arkansas Natural Heritage Commission mussel database, to update the conservation status for all native freshwater unionoid bivalves thought to occur in Arkansas. Prior to this study, Harris et al. (1997) reviewed the distribution and status of 75 freshwater mussels considered native to Arkansas and ranked 22 species as endangered, threatened or special concern. We now recognize 85 mussel taxa in Arkansas; however, some of those have yet to be described or their nomenclature …

Journal of the Arkansas Academy of Science

Currently, few data exist for the mussel assemblages of the Tyronza River, Arkansas. The goal of this project was to inventory the freshwater mussel assemblages of the Tyronza River and determine the status of the federally endangered Potamilus capax. We qualitatively and quantitatively sampled mussel assemblages and documented the occurrence of S1 (extremely rare), S2 (very rare), and S3 (rare to uncommon) species. A total of 70.4 river kilometers were sampled in 2006 and 2007 resulting in 363 sampling sites, 4030 live individuals, and 25 species. We observed a total of 1 S1, 2 S2, and 9 S3 species. Mean …

An Occupational Therapist's Manual For Animal Assisted Therapy With Emotionally Distrubed Adolescents, Ann Marie. Bilek, Hannah Osborne

Occupational Therapy Capstones

According to the comprehensive literature review, animals are currently being used as an effective tool during therapy and have been reported to promote improvement with communication, behaviors, quality of life, and self esteem of different treatment populations. Since emotionally disturbed adolescents often lack appropriate skills in the areas of communication, social interactions, self-esteem, independence, and boundaries, it can be challenging for occupational therapists to provide opportunities for development of these skills. Animal assisted therapy may be a tool that can assist in bridging the gap between the adult therapist and emotionally disturbed adolescents and provide a medium to promote skill …

An Occupational Therapists' Guide To Guillain-Barré Syndrome, Kelsey Hewitt, Stephanie White

Occupational Therapy Capstones

Guillain-Barre syndrome (GBS) is a rare polyneuropathy that affects 2,720 people per year in the United States (NIH, The National Women’s Health Centre, 2004). Guillain-Barre syndrome has a rapid onset that causes the patient to lose sensation and muscle strength within 48-72 hours. This project provides a resource for occupational therapists treating Guillain-Barre Syndrome (GBS) to access information regarding the etiology, incidence/prognosis, assessments, and course of medical treatment. The Occupational Adaptation model serves as a foundation for treatment of the product-a guide for occupational therapy intervention. Interventions are organized to be compatible with the Occupational Therapy Practice Framework (American Occupational …
