An Investigation Of The Management Options Available To Secure A Future For The Pony On Dartmoor: A Behavioural And Opinion Based Evaluation., Robyn Jessica Petrie-Ritchie

Other Faculty of Science and Engineering Theses

Abstract Robyn Petrie-Ritchie AN INVESTIGATION OF THE MANAGEMENT OPTIONS AVAILABLE TO SECURE A FUTURE FOR THE PONY ON DARTMOOR: A BEHAVIOURAL AND OPINION BASED EVALUATION. The management of the pony (Equus Caballus) herds on Dartmoor commons has become a contentious issue between all stakeholders. There are three types of pony being bred on common land and only one of these is the recognised Dartmoor breed. However all originate from the same stock thought to have been introduced by Phoenician traders around 2000 years BCE. Recent changes to export laws and consequently market demand have meant the unhandled pony from Dartmoor …

The Effects Of Lateralisation On Detour Based Problem Solving In Horses (Equus Caballus), Hannah Savin

Other Faculty of Science and Engineering Theses

Potential impact of motor laterality on equine performance has resulted in research into this aspect of equine behaviour. Many studies demonstrate that equids exhibit a preference for one side over the other but there is little evidence for directional biases. In modern day equestrian practices, equids are frequently required to manoeuvre around objects and laterality preferences may hinder or aid in this movement. The aim of this study was to investigate if horses consistently show a directional preference during a detour task. Twenty three horses of various breeds, ages and sexes were required to obtain a goal, a piece of …

Reanimating The Wound: Dermatilliomanic Practice And The First World War, Camilla Nock

Other Faculty of Arts, Humanities and Business Theses

This research project uses an exploratory painting practice to examine a melancholic shadow cast by the First World War. The mode of inquiry is predicated upon the persistence of the past in the present, and upon a personal need to purge a persisting familial grief. To inform this stance there is systematic engagement with cathartic and redemptive artworks of the twentieth century, and with the poetry of the First World War. Developments of process and emotional register are specifically prompted by the writings of William Morris, Edmund Blunden, and Ivor Gurney, and reflections on practice are sub-divided accordingly. Wilfred Owen’s …

Ecological Understanding Through Transdisciplinary Art And Participatory Biology, Brandon Ballengée

Other Faculty of Arts, Humanities and Business Theses

In this study evidence is presented that suggests transdisciplinary art practices and participatory biology programs may successfully increase public understanding of ecological phenomenon. As today’s environmental issues are often complex and large-scale, finding effective strategies that encourage public awareness and stewardship are paramount for long-term conservation of species and ecosystems. Although artists and biologists tend to stay confined to their professional boundaries, and their discourses largely remain inaccessible to larger audiences, arguments here are presented for a combined approach, which may disseminate knowledge about ecology to non-specialists through novel art-science participatory research and exhibitions. Moreover, historically several scientists utilized varied …

Pudu Jail's Graffiti: Beyond The Prison Cells, Khairul Ismail

The aim of this thesis is to examine and analyse the images of graffiti contained within the portfolio of ‘Pudu Jail’s Graffiti (PJG)’, documented work from the abandoned prison facility in Kuala Lumpur, Malaysia, between 2002 and 2003. The objective has been to discover whether the ‘Pudu Jail’s Graffiti’, has a distinct visual narrative(s) compared with other prison graffiti research, concluding that its qualities lies in the complexity of visual cultures brought within the space of the prison cells. The prison graffiti retrieved from this portfolio has been analysed through a process of qualitative review; in order to find its …

Using Geographical Information Systems To Investigate Access To School Mental Heath Services, Heather L. Mcdaniel

Theses and Dissertations

Many youth present emotional or behavioral difficulties at levels that necessitate mental health services, yet few receive these needed services. However, school mental health services are thought to improve access to mental health services for youth and families over and above traditional community mental health centers. The purpose of the current study was to expand on existing research by examining community-level and geographic predictors of the utilization of school mental health or community mental health services. Within the context of a large, federally funded trial, I examined how community rurality, ethnic/racial makeup and drive time predicted the use of either …

“Tal Vez Sueña De Estas Cosas/ Maybe He Dreams Of These Things:” Envisioning Possibilities For Multilingual Learners In The Culturally Responsive Rural Classroom, Evelyn Spradley Stockdale

Theses and Dissertations

Meeting the needs of multilingual learners is a growing concern for many classroom teachers across the nation as school-age populations in the United States continue to become more ethnically, culturally, and linguistically diverse. Teachers often have little understanding of diverse learners and frequently express misconceptions about these students and their cultures. The purpose of this qualitative multiple case study was to explore the social, cultural, and linguistic resources multilingual learners draw upon and the literacy practices they enact during reading and writing workshop when culturally responsive pedagogy (CRP) is implemented. This study also examined how culturally relevant (CR) texts and …

Evidence Of Things Not Seen: A Semi-Automated Descriptive Phrase And Frame Analysis Of Texts About The Herbicide Agent Orange, Sarah Beth Hopton

USF Tampa Graduate Theses and Dissertations

From 1961 to 1971 the United States and the Republic of South Vietnam used chemicals to defoliate the coastal and upload forest areas of Viet Nam. The most notorious of these chemicals was named Agent Orange, a weaponized herbicide made up of two chemicals that, when combined, produced a toxic byproduct called TCDD-dioxin. Studied suggest that TCDD-dioxin causes significant human health problems in exposed American and Vietnamese veterans, and possibly their children (Agency, U.S. Environmental Protection, 2011). In the years since the end of the Vietnam War, volumes of discourse about Agent Orange has been generated, much of which is …

Assessment Of The Impact Of Attention Deficit Hyperactivity Disorder On Type 1 Diabetes, Kellee Miller

USF Tampa Graduate Theses and Dissertations

Individual day-to-day management and effective control of type 1 diabetes (T1D) is ultimately driven by decisions made by the individual. Individuals with attention deficit hyperactivity disorder (ADHD) have a higher tendency to be inattentive, impulsive, and hyperactive. Attention deficits and impulsivity among adolescents and adults with T1D could result in poor diabetes management through infrequent self-monitoring of blood glucose and inadequate insulin dosing – key components of achieving optimal glycemic control.

This study included 7,380 adolescents and young adults, ages 13-25 years, participating in the T1D Exchange clinic registry (median age 17.4 years, duration 7.7 yrs, 50% female, 81% white). …

Exploring The Interactive Effects Of Social Learning Theory And Psychopathy On Serious Juvenile Delinquency, Brandy Barenna Henderson

USF Tampa Graduate Theses and Dissertations

Social learning theory continues to be one of the most enduring theories of crime. Psychological criminology, on the other hand, tends to explain crime in terms of behavioral propensities. This research is specifically focused on the generality of social learning theory as it varies across a measure of criminal propensity- in this case, psychopathy. Prior studies have tested various theories with the use of measures of propensity, but the theory is rarely social learning, and the measure of propensity has never been psychopathy. The current study examines three components of social learning theory (definitions, differential association, and differential reinforcement) to …

Impacts Of Agrochemical Pollution On Aquatic Communities And Human Disease, Neal T. Halstead

USF Tampa Graduate Theses and Dissertations

The global human population is expected to exceed 9 billion individuals by 2050, putting greater strain on the natural resources needed to sustain such a population. To feed this many people, some expect agricultural production will have to double and agrochemical use will have to increase anywhere from two- to five-fold relative to the turn of the century. Although industrial agriculture has provided many benefits to society, it has caused declines in biodiversity, both directly (e.g., through conversion of habitat) and indirectly (e.g., through contamination of adjacent natural habitats). Agricultural activity has also been linked to increased prevalence and intensity …

Neural Correlates Of Inhibitory Function Following The Implicit Processing Of Emotional Faces, Lorri A. Kais

Master's Theses

Emotion and cognitive function interact to play a central role in determining

human thought and behavior. Attention to emotion can facilitate or hinder cognitive

control efforts based on the given contextual demands of the task at hand. This study used

scalp electroencephalography (EEG) methods to examine the link between valence of

facial stimuli and neural changes associated with emotional face processing and

subsequent inhibitory response. 20 participants completed a gender discrimination stop-

signal task using emotional faces. Facial valence did not differentially modulate the P200

event-related potential (ERP), indicating that happy and sad faces recruit similar neural

resources in the …

The Effects Of Stress And Alcohol On Hiv-1 Latency, Sarah Ilene Talley

Master's Theses

A major barrier to HIV eradication is the persistence of latent viral reservoirs that exist despite antiretroviral therapy. In order to develop effective therapeutics, a comprehensive understanding of latency and factors driving the formation of the latent reservoir is needed. As stress and alcohol are common comorbidities associated with HIV infection, the goal of this research was to determine how stress and alcohol could affect HIV-latency. Specifically, we hypothesized that the ability of latent proviruses to be reactivated by “shock and kill” approaches would be altered by glucocorticoid and ethanol treatments, and prolonged ethanol exposure would affect the size of …

Utilizing Galectin 3 As A Marker Of Ruptured Vesicles In Vivo, Jonathan London

Master's Theses

Ruptured vesicles have been associated with pathological forms of α-synuclein during the development of PD. Galectin 3 (Gal3) is readily recruited to these ruptured vesicles, making it a potentially useful marker of vesicle rupture in PD and other diseases associated with vesicle rupture and lysosomal dysfunction. We were able to visualize and quantify the differences in Gal3 levels during infection with pathological α-synuclein in the rat brain. Having significantly high basal levels of Gal3, we found that the differentiated monocytes showed a nearly100 percent increase in intercellular levels of Gal3 after treatment with pathological α-synuclein. By expressing only the Carbohydrate …

Characterization Of Exopolysaccharide (Eps) Produced By Bacillus Subtilis Mutants, Alexander Argianas

Master's Theses

Bacillus subtilis is a probiotic bacterium that can protect against the murine-

specific attaching and effacing (A/E) pathogen Citrobacter rodentium. C. rodentium displays many features observed with the human pathogen enteropathogenic E. coli (EPEC). Protection by B. subtilis is mediated by exopolysaccharide (EPS), which is encoded by the epsA-O operon that contains 15 genes. Disruption of one of these genes, epsH, which appears to encode a putative glycosyltransferase, leads to the loss of protective capacity by B. subtilis and by EPS. EPS is a major component of the B. subtilis biofilm and the ΔepsH mutant is unable to form a …

Role Of Heat Shock Proteins In Maintenance Of The Gut Barrier Following Burn Injury, Abigail Rhea Cannon

Master's Theses

Introduction: Burn injury remains a prominent clinical problem. Patients suffering from burns often succumb to secondary infectious complications leading to sepsis and widespread tissue injury ending in Multiple Organ Dysfunction. However, the mechanism behind the onset of these extraneous symptoms following burn injury is not fully understood. The integrity of the gut barrier is of critical importance as it harbors the largest bacterial reservoir in the body. Following burn injury, we observed a breakdown of the gut barrier resulting in increased gut leakiness and bacterial translocation. Under homeostatic conditions, heat shock proteins (HSPs) stabilize tight junction proteins. Particularly, HSP72 is …

Separating Autoimmune And Anti-Tumor Responses With Hsp70iq435a, James Mahon

Master's Theses

Vitiligo and melanoma are both melanocyte-derived diseases; vitiligo progresses through the autoimmune-targeted destruction of healthy melanocytes while melanoma results from uncontrolled proliferation of cancerous melanocytes. Treatment of vitiligo with HSP70iQ435A inhibits the DC-mediated auto-immune response against melanocytes in vitiligo mouse models; this raises the concern that treatment with this modified HSP may also inhibit natural anti-tumor responses against melanocyte-derived melanoma tumor cells.

We hypothesized that HSP70iQ435A prevents migration of melanocyte-antigen reactive T cells to the skin in a way that is mechanistically different from anti-tumor responses to melanoma and therefore would not have a negative effect on anti-tumor responses. We …

Anthropogenic Litter And Microplastic In Urban Streams: Abundance, Source, And Fate, Amanda Rae Mccormick

Master's Theses

The accumulation and ecological effects of anthropogenic litter (AL) and microplastic are well-documented in marine ecosystems, but these materials’ abundances in rivers is unknown. AL enters rivers from recreation, runoff, and illegal dumping. Microplastic fibers and pellets are abundant in wastewater treatment plant (WWTP) effluent which enters rivers. Our objectives were to: (1) quantify AL abundance and composition in urban streams, (2) measure AL flux, accumulation, and export, and (3) measure riverine microplastic concentration and analyze its bacterial communities. We collected AL from 5 urban streams and observed greater AL density in riparian habitats and greater mass in benthic habitats. …

The Role Of Central Metabolism And Electron Transport In Biofilm Formation By Vibrio Fischeri, Jakob Michael Ondrey

Master's Theses

Biofilms protect bacteria from environmental threats, including antibiotics; thus, biofilms formed during infections pose an increasing threat to human health. A natural model used to study biofilm formation in the context of a host is the symbiosis between Vibrio fischeri and its host, the squid Euprymna scolopes. Successful colonization depends on the formation of a biofilm and genes involved in making the polysaccharide matrix component, syp. In culture, biofilm phenotypes, including the formation of wrinkled colonies, similarly depend on syp. However, little is known about other factors that contribute to this phenotype. To expand the utility of currently available genetic …

Malaria Transmission Blocking Vaccines, Lukasz Jacek Sewera

Master's Theses

Malaria affects 198 million people and kills 584,000 each year, predominantly in Sub-Saharan Africa (WHO). The most severe form of malaria is caused by the protozoan parasite Plasmodium falciparum. Development of a vaccine against P. falciparum has been hindered by its complex life cycle with multiple antigenically distinct human and mosquito stages. To effectively prevent disease and reduce the parasite burden in populations, a vaccine will need to target multiple stages, including blocking transmission at the mosquito stage.

Antibodies generated against P. falciparum mosquito stage antigen Pfs25 can prevent parasite transmission from humans to mosquitoes. However, Pfs25 is poorly immunogenic …

The Influence Of Eastern Oyster (Crassostrea Virginica) Reef Restoration On Nitrogen Cycling In A Eutrophic Estuary., Michael Hassett

Master's Theses

Oysters (Crassostrea virginica) are functionally extinct in the urbanized Hudson-Raritan estuary (HRE) in New York City, however, oyster restoration is promoted to mitigate nitrogen (N) pollution via oysters' filtration and excretion. Seasonally, I took 12 sediment cores (45 cm2) adjacent to and 10 m away from a recently constructed reef in the HRE. Cores were incubated in flow-through chambers with site water containing (1) no amendments, (2) 15N-ammonium, or (3) 15N-nitrate, from which I calculated coupled nitrification-denitrification and direct denitrification as isotope-enriched N2. Coupled denitrification was minimal at all sites while direct denitrification was elevated near the reef, suggesting organic …

Investigating The Role Of Cysteine In Biofilm Formation By Vibrio Fischeri, Priyanka Abhishek Singh

Master's Theses

Biofilms are an important area of medical research because bacterial biofilms can form on implants such as catheters and are highly resistant to antibiotics and other antimicrobials. The symbiosis between Vibrio fischeri-Euprymna scolopes, is good model to study biofilm. V. fischeri has 18 gene polysaccharide locus, syp, that is required for biofilm formation and colonization. A recent mutant study suggested the possibility that cysteine biosynthetic genes were involved in biofilm formation by V. fischeri, including cysH, cysJ, cysK, and cysN. My results supported a role for cysK and, to a lesser extent, cysH in biofilm formation. Finally, I have data …

Moral Injury In Veterans : A Theoretical Investigation Of The Psychic, Moral And Social Sequelae Of War Trauma, Sarah C. Towers

Theses, Dissertations, and Projects

Although the idea that a violation of deeply held moral and ethical values can result in a profound psychic, social and spiritual wounding is an ancient one, the exploration of the phenomenon of moral injury in the field of mental health has only recently gained traction. Moral injury is increasingly being regarded as its own psychological phenomenon, one that shares symptomology with PTSD, but is also distinct, and as yet not sufficiently accounted for in current PTSD criteria. This theoretical thesis charts the evolving clinical construct of moral injury and draws on two bodies of theory, narrative theory and adult …

The Domestication And Migration Of Zea Mays L. In Association With Holocene Climatic Variance, Kelsey L. Salmon Schreck

Senior Independent Study Theses

Maize is known to have originated in Mesoamerica from which it spread north and south, adapting to many varied climatic and environmental conditions. This study details the origin of the species Zea mays L. The teosinte hypothesis and the concepts of seasonality and scheduling are employed to discuss the domestication of maize by means of human selection. This information is used to highlight the basic circumstances necessary for maize agriculture to be adopted by a human population. Furthermore, climate is examined through the minimum and ideal environmental conditions needed for the successful growth of maize. Environmental cues play a profound …

Learning Emotions: A Software Engine For Simulating Realistic Emotion In Artificial Agents, Douglas Code

Senior Independent Study Theses

This paper outlines a software framework for the simulation of dynamic emotions in simulated agents. This framework acts as a domain-independent, black-box solution for giving actors in games or simulations realistic emotional reactions to events. The emotion management engine provided by the framework uses a modified Fuzzy Logic Adaptive Model of Emotions (FLAME) model, which lets it manage both appraisal of events in relation to an individual’s emotional state, and learning mechanisms through which an individual’s emotional responses to a particular event or object can change over time. In addition to the FLAME model, the engine draws on the design …

Masculine Space: The Final Frontier; A Historical Analysis Of The Spatial Politics Of Gender Through The New Woman’S Access To Brassieres, Bicycles, And Higher Education In The United States From 1890-1930, Shelby Kirst Goldman

Senior Independent Study Theses

1890-1930 was a time of major social and cultural shifts as the Victorian conventions clashed with progressive and changing ideas of gender, race, and class, resulting in the liberated American New Woman. This thesis examines the transition of the opportunities for increased physical movement for women allotted by the popularization of the brassiere, bicycle, and access to higher education. Examining the brassiere and bicycles’ impact on women’s liberation lends insight into how the physical placement and movement of female bodies confronted gender norms, while expansion of women’s education made women intellectual threats to the patriarchal structure. My analysis of advertisements …

Selective Processing By The L3 Auditory Interneuron In Acheta Domesticus : Juvenile Hormone Iii And Protein Kinase C, Ashley Ranae Lynch

Master's Theses

Juvenile Hormone III (JHIII) is a prolific and essential hormone in insects, controlling many aspects of insect physiology such as egg development, nymphal and larval maturation, diapause and metamorphosis. In female crickets, Acheta domesticus, JHIII increases selectivity in phonotactic behavior, narrowing phonotactic choices for Syllable Periods (SPs) of the Calling Songs (CSs) that most closely resemble the natural call of the male. JHIII has been suggested to work through a pathway that activates the protein kinase C (PKC) molecule. Chelerythrine Chloride (CC) is a potent inhibitor of PKC action. This study analyzes the responses of the L3 auditory interneuron, which …
