The Effects Of A Valproate Fatty Acid Prodrug On The Inositol Biosynthetic Pathway, Gina Kang

Honors Theses

Bipolar disorder is characterized by alternating episodes of mania and extreme depression. Compounds such as omega-3 fatty acids and valproate individually treat symptons of bipolar disorder, one of which is elevated inositol levels. Lithium and valproate are known to reduce iniositol levels. The goal of this project is to combine linoleic acid (an omega-3 fatty acid substitute) with valproate and observe the prodrug's effects on the inositol biosynthetic pathway using Saccharomyces cervisiae yeast as the model system. Since inositol is required for growth, the effects of the prodrug on the inositol biosynthetic pathway was determined by comparing its impact on …

Never Two Ladies Lov'd As They Do: Queer Theory And As You Like It's Celia, Theron L. Calkins

Honors Theses

Though most performances of William Shakespeare's As you like it focus on the comedy of Ganymede/Rosalind's interactions with Orlando, director Des McAnuff's 2012 Stratford Shakespeare Festival production instead manifests homoerotic tension between Celia and Rosalind. Shakespeare's textual allusions provide ample evidence to support this homoerotic reading which McAnuff actualizes between Cara Rickett's Celia and Andrea Runge's Rosalind through blocking and speech inflection. My analysis encompasses a detailed investigation of this particular production as well as a study of homoerotic desire between women, faciliating a critique of the methods of queer theory by engaging and refining its generalized critical principles.

Reproductive Success Of Gulls In The Larus Glaucescens-Occidentalis Complex On Protection Island, Washington, Libby C. Megna

Master's Theses

Glaucous-winged Gulls (Larus glaucescens) and Western Gulls (Larus occidentalis) hybridize extensively where their ranges meet along the coasts of Washington and Oregon, producing a continuum of phenotypic intergrades between the two parental species. Previous work has shown that hybrids can experience greater reproductive success than parental types by combining adaptive behaviors, such as nest site selection, of both parental species, although success of hybrids may be affected by shifts in the ecotone between marine upwelling and non-upwelling environments. I investigated whether there is a correlation between phenotype, reproductive success, and nest site choice for gulls in Protection Island National Wildlife …

Effect Of Velvetleaf Root Exudates On Indole-3-Acetic Acid Production By Rhizobium Rubi At3-4rs/6, Amy Nadane

Honors Theses

Rhizobium rubi AT3-4RS/6 was isolated from the velvetleaf rhizosphere and is being tested as a potential biological control of velvetleaf. The purpose of this research is to test the levels of indole-3-acetic acid (IAA) produced by Rhizobium rubi AT3-4RS/6 after exposure to and incubation in velvetleaf root exudates. IAA production has been found in other rhizobacteria that are deleterious to weed growth. Velvetleaf seeds were sprouted and the roots suspended in a sterile mineral solution, which was then recovered and inoculated with R. rubi. Levels of IAA and numbers of viable bacterial colonies were then determined. The average level of …

The Effect Of 4-Aminopyridine On Phonotactic Selectivity In Female Crickets, Lauren Martin

Honors Theses

My research project was designed to explore the effects of 4-aminopyridine (a potassium channel blocker) on phonotactic selectivity in female crickets, Acheta domesticus. These crickets underwent pre-tests for selectivity on a non-compensating treadmill during which their response to a range of male calling songs (30-90ms syllable periods) was recorded. A solution of 9.2 nl of saline or 10(-5)M 4-aminopyridine was nanoinjected into the supraesophageal ganglion. After a ten-minute recovery period, post-tests were performed, identical to the pre-tests. There was no significant effect of 4-aminopyridine on the females' selectivity.

An Evaluation Of Electrical Conductivity As A Practical Tool In Mastitis Detection At Andrews University Dairy, Carrie Mesiar

Honors Theses

An infection in a cow's udder, also known as mastitis, has been a persistent problem for the U.S. dairy community. Mastitis not only decreases milk production, but also shortens the productive life of dairy cattle and can be fatal if left untreated. Mastitis presents in both subclinical and clinical forms - clinical is easy to diagnose and treat, whereas subclinical cases are much harder to detect as they present no physical symptons, yet can still become clinical in time. At the Andrews University Dairy, part of the milking system includes electrical conductivity (EC) determination which measures the ionic composition of …

Developing An Intracellular Neurobiology Lab Sequence For Use In An Interdisciplinary Neurobiology Course, Aleksandra Kozlova-Harris

Honors Theses

The goal of my research was to evaluate procedures currently used in the Intracellular Leech Lab in order to modify the Neurobiology ZOOL475 Lab to increase the rate of successful intracellular recordings for future Neurobiology students. Two approaches were used: the first was to evaluate the possibility of using a less expensive leech species in order to allow students unlimited attempts at recording from ganglia without budget constraints. The second was to evaluate various raising conditions (water, temperature, and age) to optimize the quality of the leech ganglia. Both approaches provided useful information to improve lab success.

The Effects Of Chloro Linoleate Acylal Prodrugs On The Inositol Biosynthetic Pathway In Saccharomyces Cerevisiae, Steffie-Ann Dujon

Honors Theses

Bipolar disorder is a debilitating mental illness characterized by recurrent episodes of mania and depression. FDA-approved drugs lithium and valproate, are the most common treatments for this disorder. Currently, omega-3 fatty acids are being researched as an alternative treatment, free of the negative side effects valproate and lithium exhibit. The mechanisms by which valproate and lithium work are unclear, however they effectively lower intracellular inositol levels. Valproate and omega-3 fatty acids similarly inhibit yeast cell growth as well as protein kinase C activity. We hypothesize that omega-3 fatty acids can also decrease inositol levels. A prodrug combining structural properties of …

No. 334: A Visual Exploration Of Race And Identity, Naudline Pierre

Honors Theses

Throughout history, humans have invented several methods of classification - most of which are unsettling. The human need to classify is one that is deeply rooted in the search for identity. The need to fit, the need to explain, and the need to rationalize the world around us is a powerful incubator in which the process of human classification takes place. Although this thesis project involves a substantial amount of research, it is essentially a documentation of my journey to finding my identity through the lens of human classification based on physical attributes. Through the research of various human classification …

The Effects Of Pyrilamine On The Selectivity Of Phonotaxis, Kristin Chung

Honors Theses

Hormones modulate phonotactic behaviors of female crickets (Acheta domesticus). This project seeks to observe the changes in phonotactic behavior when anti-histamine is injected in the prothoracic ganglion. The anti-histamine used, pyrilamine, resulted in older, unselective females becoming more selective to the male calling songs. Females injected with saline (controls) remained unselective. The experiments with pyrilamine (anti-histamine) validates histamine's proposed role on phonotactic selectivity by enhancing inhibition of syllable period selective neural circuits in the prothoracic ganglion.

Intraindividual Variation In The Calling Songs Of The Cricket Gryllus Pennsylvanicus, Lauren Van Putten

Honors Theses

The goal of this project was to examine intraindividual variability in the calling song of the male cricket, Gryllus pennsylvanicus. We evaluated syllable period and chirp period lengths under both constant and changing temperature conditions. Significant variability in chirp and syllable period length was found under constant conditions, suggesting males are subject to internal variability without any effects from the environment. Significant variability was also seen in chirp and syllable period length for crickets under changing temperature condtions. There was a two to five minute delay in response to the temperature change.

Mating Patterns And Breeding Success In The Larus Glaucescens-Occidentalis Complex, Protection Island, Washington, Andre E. Moncrieff

Honors Theses

Glaucous-winged gulls (Larus glaucescens) and Western gulls (Larus occidentalis) are found along the Pacific Coast. Where their breeding ranges overlap in Oregon and Washington they hybridize, producing a continuum of phenotypic variation. Whereas most colonies containing these hybrids are found on islands along the coast, several, including a large colony on Protection Island National Wildlife Refuge, WA, are located in the Salish Sea. In 2010 I scored the henotypes of 81 gull pairs at the Protection Island cology using an index based on plumage melanism and bare-part coloration. Gulls from the entire range of phenotypes in the L. glaucescens-occidentalis complex, …

Ethnic Group Affiliation And Social Exclusion In Cornwall; Analysis, Adjustment And Extension Of The 2001 England And Wales Census Data, Kerryn Husk

School of Law, Humanities and Social Sciences Theses

This thesis provides a critical understanding of the size and relative position of the Cornish in Cornwall, a county in the south-west of the UK. Cornwall is a region which has experienced increased levels of disadvantage for a prolonged period of time. The indigenous people, whilst seeing a rise in their inclusion in ethnicity variables in the region, have remained under-researched in terms of their socio-economic position relative to the non-Cornish in the same geographic area. This thesis addresses this gap in the literature and represents the first in-depth examination of the group. The 2001 Census included an option to …

Toward A Holistic Interdisciplinary Model Of Human Being: A Hebraic-Christian Perspective Of The Human Observer And Its Beneficial Impact On The Theology-And-Science Dialogue, Society, And The Environment, Karen K. Abrahamson

Dissertations

Problem

A challenge faced by the theology-and-science dialogue is how to effectively communicate across disciplinary lines. The community assumes that there is a methodology or cluster of methodologies that allows for interdisciplinary conversation to take place. However, the community is not in agreement about how this process should occur or the hermeneutical principles that should guide it. Is it possible to surmount the problem of methodological compatibility and to generate mutually beneficial and fruitful dialogue through seeking a point of commonality between all the disciplines of the theology-and-science dialogue?

Purpose

The purpose of this dissertation is to discover a philosophical …

Temporal Dynamics Of Galapagos Marine Iguna (Amblyhynchus Cristatus) Haulout, Brianna Gale Payne

Master's Theses

Galápagos marine iguanas (Amblyrhynchus cristatus) briefly forage in marine habitats but spend their remaining time hauled out on land. A wide range of diurnal activities, from social and thermoregulatory behaviors to sleep and food processing, occurs during haulout. To understand the dynamics of haulout and foraging in relation to environmental factors, I fit compartmental models derived from ordinary differential equations to field data collected daily from 30 April to 16 May 2011 at two sites—one Sandy and one Rocky—at Cabo Douglas, Isla Fernandina. The best model for haulout at the Sandy site accounts for 77–80% of observed variability and includes …

Fabrication And Mechanical Properties Of Chitosan Composite Membrane Containing Hydroxyapatite Particles, Hr Le, S Qu, Re Mackay, R Rothwell

School of Biological and Marine Sciences

This paper described the development of chitosan composites containing precipitated hydroxyapatite particles for potential applications in orthopaedic surgery or waste water treatment. The synthetic process and morphology of hydroxyapatite were reported. The effects of hydroxyapatite content on the microstructure and mechanical properties of composites were investigated. It was found that the Young’s Modulus of the composites decreases with hydroxyapatite content while the failure strength and strain increase with the hydroxyapatite content.

There Is No Evidence For A Temporal Link Between Pathogen Arrival And Frog Extinctions In North-Eastern Australia., Ben L. Phillips, Robert Puschendorf, Jeremy Vanderwal, Ross A. Alford

School of Biological and Marine Sciences

Pathogen spread can cause population declines and even species extinctions. Nonetheless, in the absence of tailored monitoring schemes, documenting pathogen spread can be difficult. In the case of worldwide amphibian declines the best present understanding is that the chytrid fungus Batrachochytrium dendrobatidis (Bd) has recently spread, causing amphibian declines and extinction in the process. However, good evidence demonstrating pathogen arrival followed by amphibian decline is rare, and analysis of putative evidence is often inadequate. Here we attempt to examine the relationship between Bd arrival and amphibian decline across north-eastern Australia, using sites where a wave-like pattern of amphibian decline was …

Impacts Of A Parenting Newsletter On Fathers Of Kindergarten Children, Sean E. Brotherson, Erin Kramer Holmes, Christopher J. Bouwhuis

Faculty Publications

This study is the first assessment of the perceived effectiveness of a parenting newsletter written specifically for fathers or father figures. The Father Times newsletter was distributed weekly for six weeks to all families of kindergarten children at a local school. Once hundred seventy-seven fathers responded to a self-report questionnaire regarding usage of the parenting newsletter, perceptions of the newsletter as a resource, and impacts of fathers' attitudes, knowledge, behaviors, and father–child relationship quality. Two-thirds of fathers in the sample reported changing at least "somewhat" in all nine outcomes explored. Neither father age nor number of children in the home …

Theism And Psychological Science: A Call For Rapprochement, Michael J. Vogel, Tyler A. Gerdin, Mark R. Mcminn

Faculty Publications - Doctor of Psychology (PsyD) Program

The authors offer two arguments for the inclusion of theism in natural science. First, an argument against excluding theism is offered. Though early roots of science promoted a view that it is a way to accumulate knowledge that is untainted by presuppositions and traditions, postmodern critiques call this into question. Scientists have sometimes rejected religion as a context-dependent, tradition-based way of knowing, yet science itself is also context-dependent and tradition-based. Second, an argument for including theism in psychological is offered. Theistic beliefs are relevant insofar as they are part of human experience for many, they represent a form of human …

Bad News For John Marshall, Gary S. Lawson, David Kopel

Faculty Scholarship

In "Bad News for Professor Koppelman: The Incidental Unconstitutionality of the Individual Mandate," we demonstrated that the individual mandate’s forced participation in commercial transactions cannot be justified under the Necessary and Proper Clause as the Clause was interpreted in McCulloch v. Maryland. Professor Andrew Koppelman’s response, "Bad News for Everybody," wrongly conflates that argument with a wide range of interpretative and substantive positions that are not logically entailed by taking seriously the requirement that laws enacted under the Necessary and Proper Clause must be incidental to an enumerated power. His response is thus largely unresponsive to our actual arguments.

Awareness With Accuracy: An Analysis Of The Representation Of Autism In Film And Television, Lacreanna S. Young

Research Papers

This was a study analyzing accuracy and stereotypes about autism representation in Rain Man, Mercury Rising, Parenthood, and Arthur. The autistic characters were viewed a minimum of five times. Their behaviors were compared with common myths about autism as presented by the Autism Research Institute. Autistic characters were labeled as dispelling or reinforcing the five myths analyzed. Production efforts to be scientifically accurate and autism representation since the release of Rain Man were also analyzed. While the media analyzed did utilize various efforts to represent autism accurately, this study found that each medium relied upon many …

Hospital Loneliness And The Patient-Physician Relationship: A Preliminary Analysis Of Associations With Recovery In Bone Marrow Transplant Patients, Lindsay E. Balfour

UNF Graduate Theses and Dissertations

The purpose of the present study was to examine general loneliness, hospital loneliness, and the patient-physician relationship in regards to their associations with Bone Marrow Transplant (BMT) recovery outcome variables (days until engraftment and quality of life). Fifteen (66.7% female, 33.3% male; 93.3% white, 6.7% Black/African American; average age 61.73) individuals who had an allogeneic or autologous BMT at The Mayo Clinic of Jacksonville completed the FACT-BMT, UCLA-Loneliness Scale Version 3, the CARE Measure, and provided disease and treatment information at the 6 month posttransplant date (+/- 30 days). Patients recovering from BMT indicated significantly higher scores of hospital loneliness …

Abundance, Distribution, And Habitat Use Of Sharks In Two Northeast Florida Estuaries, Michael Philip Mccallister

UNF Graduate Theses and Dissertations

Sharks are considered top predators in many marine ecosystems, and can play an important role in structuring those communities. As a result, it is necessary to understand the factors that influence their abundance and distribution. This is particularly important as fishery managers develop fishery management plans for sharks that identify areas that serve as essential fish habitat (EFH). This includes nursery habitat where sharks are born and juveniles spend the early part of their life. However, our understanding of shark habitat use in the northeast Florida waters is limited. The goal of this thesis was to characterize the abundance and …

Nutrient Transport By Shrimp Hepatopancreas, Tamla A. Simmons

UNF Graduate Theses and Dissertations

Purified brush border membrane vesicles (BBMV) were isolated to characterize primary cellular transport mechanisms for white shrimp. The ultimate goal is to determine the effective components of a shrimp’s diet, thereby enhancing growth, as well as nutrient content. Juvenile shrimp are dependent on plant material as a food source. Potassium is a key component of plants, thus it may play a role in nutrient transport. In addition, divalent metals have been shown to act as co-transporters in several other organisms, thus they may serve as a transport mechanism for shrimp.

Fresh, live, white or brown shrimp were obtained, and from …
