Mirrors, Wolves And Tornadoes-Oh My! An Intertextual Exploration Of Guillermo Del Toro's Pan's Labyrinth, Pamela Painter Decius

USF Tampa Graduate Theses and Dissertations

I argue that Guillermo Del Toro is a modern day storyteller, writing his film script as Ovid, The Grimms, or even Baum would pen their tales. I expand the idea of intertextuality to include not only conversations, thoughts, architecture, emotions, bodily activity, sounds, and innumerable other signifiers, but also analyzing the film "inter-imagically." By considering the film in this way it encourages a world conversation that can influence socio-political transformations in our world.

I use the stories and images in myth, fairy tale and children's literature to support the importance of agency, agency in regard to finding your own voice, …

The Role Of Abiotic And Biotic Factors In Suspension Feeding Mechanics Of Xenopus Tadpoles, William G. Ryerson

USF Tampa Graduate Theses and Dissertations

As a comparison to the suction feeding mechanics in aquatic environments, I investigated buccal pumping in an ontogenetic series of suspension feeding Xenopus laevis tadpoles (4-18 mm snout-vent length) by examining the morphology, kinematics, fluid flow, pressure generated in the buccal cavity, and effects of viscosity manipulation. Investigation of the dimensions of the feeding apparatus of Xenopus revealed that the feeding muscles exhibited strong negative allometry, indicating that larger tadpoles had relatively smaller muscles, while the mechanical advantage of those muscles did not change across the size range examined. Buccal volume and head width also exhibited negative allometry: smaller tadpoles …

Determining Fort Walton Burial Patterns And Their Relationship Within The Greater Mississippian, Gabrielle Shahramfar

USF Tampa Graduate Theses and Dissertations

The objective of my research was to compile all known burial data from the Fort Walton culture located in northwest Florida (A.D. 1000 to contact) to determine any patterns in burial practices. A thorough literature review of all published material was conducted to obtain the burial data. I also reviewed burial practices of other contemporaneous late prehistoric cultures in the Southeast, including the Pensacola and Rood cultures. The burial data clearly indicate that Fort Walton burial practices varied greatly; 14 different burial types were identified from all of the sites. A similar pattern is seen among Pensacola, Rood and Mississippian …

Can Waters Around Durney Key, Pasco County, Florida, Support Coral Recruitment To Artificial Substrates?, Kelley L. Anderson

USF Tampa Graduate Theses and Dissertations

To determine whether an artificial reef installation is feasible, there must be a thorough characterization of the habitat. An understanding of both small-scale and large-scale environmental processes is needed to determine factors that potentially will influence the reef. Large-scale processes include coastal circulation, wave climate, and sediment dynamics that take place over spatial scales of tens to hundreds of kilometers in the region of the reef. Small-scale processes include the physical characteristics in the immediate vicinity of the reef - the local current, wave and tide characteristics, temperature, salinity, and suspended and bottom sediments at a proposed reef site.

Involvement Of 5-Ht2a Receptor In The Regulation Of Hippocampal-Dependent Learning And Neurogenesis, Briony J. Catlow

USF Tampa Graduate Theses and Dissertations

Aberrations in brain serotonin (5-HT) neurotransmission have been implicated in psychiatric disorders including anxiety, depression and deficits in learning and memory. Many of these disorders are treated with drugs which promote the availability of 5-HT in the synapse. Selective serotonin uptake inhibitors (SSRIs) are known to stimulate the production of new neurons in the hippocampus (HPC) by increasing synaptic concentration of serotonin (5-HT). However, it is not clear which of the 5-HT receptors are involved in behavioral improvements and enhanced neurogenesis. The current study aimed to investigate the effects of 5HT_2A agonists psilocybin and 251-NBMeO and the 5HT_{2A/C …}

Monocytes As Gene Therapy Vectors For The Treatment Of Alzheimer’S Disease, Lori Ann Lebson

USF Tampa Graduate Theses and Dissertations

The accumulation of amyloid-ß; protein (Aß) in Alzheimer's disease (AD) is a well known pathological event. Decreasing the production or increasing the degradation of Aß; is therefore thought to serve as a potential therapeutic intervention in AD. Recent in vitro and in vivo studies have suggested that certain proteases may be involved in the catabolism of Aß; and defects in the degradation of Aß; could contribute to AD disease progression. Studies implicating the homing of monocytes to regions of CNS damage have led to the idea that it may be possible to use genetically modified monocytes to carry exogenous genes …

Modeling Upper Body Kinematics While Using A Transradial Prosthesis, Derek J. Lura

USF Tampa Graduate Theses and Dissertations

The prostheses used by the majority of persons with upper limb amputations today offer a limited range of motion. Relative to anatomical joints transradial (below the elbow) prosthesis users lose at least two of the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer active degrees of freedom. In order to perform activities of daily living, an amputee must use …

Contradictions In A Distance Content-Based English As A Foreign Language Course: Activity Theoretical Perspective, Irshat Madyarov

USF Tampa Graduate Theses and Dissertations

This study explores six English as a foreign language students in an English content-based course of critical thinking delivered via distance at the Bahá'í Institute for Higher Education (BIHE) in Iran. Framed within cultural-historical activity theory, the study seeks to shed light on the complex nature of students' course-related activities with a particular focus on contradictions that underlie any human activity. The construct of contradictions provides a theoretical lens to understand the complex web of relationships among a number of elements in the course taking activity situated in a cultural-historical setting beset with political controversies, technological challenges, and demands of …

The Biomechanics And Evolution Of Shark Teeth, Lisa Beth Whitenack

USF Tampa Graduate Theses and Dissertations

Measuring the effects of morphology on performance, and performance on fitness, is necessary to gain a full picture of selection, adaptation, ecology, and evolution. The performance of an organism's feeding apparatus, of which teeth are an integral part, has obvious implications for its fitness and survival. Extant shark teeth encompass a wide variety of shapes, and are often ascribed qualitative functions without any biomechanical testing, employing terminology such as gripping, piercing, crushing, cutting, or tearing. Additionally, teeth also comprise the vast majority of the fossil record of sharks. Therefore to understand the evolution of the shark feeding mechanism, we must …

Blank Power: The Social And Political Criticism Of Blank Fiction And Cinema, Ashley Minix Donnelly

USF Tampa Graduate Theses and Dissertations

This dissertation explores a style of literature known as "blank" fiction that became popular in the United States in the mid-1980s, focusing on its stark, limited form, its minimal plots, its focus on commodification, and its scenes of graphic violence. The author presents the argument that filmmakers were producing pieces of cinema during the same time period that are similar in both form and content to the works of blank fiction. These films are a part of a style she labels "blank" cinema.

Blank fiction and cinema are politically charged and highly critical of the social and political situation in …

Investigation Of Visual Fields And Visually-Mediated Behavior In The Bonnethead Shark (Sphyrna Tiburo), Amy L. Osmon

USF Tampa Graduate Theses and Dissertations

The goal of this dissertation was to further examine the visual system and its importance to the bonnethead shark (Sphyrna tiburo). This species of hammerhead shark possesses the least amount of lateral cephalofoil expansion. Better understanding of their visual system and potential visually-mediated behaviors may increase understanding regarding adaptive benefits of their unique head shape. The dissertation revealed four factors regarding this species' visual system: 1) the extent of their optical visual fields span between 68-72 degrees laterally and cover their visual horizon, 2) they possess a fairly large (approximately 112 degree) blind spot directly in front of …

Prey-Size Selectivity In The Bivalve Chione In The Florida Pliocene-Pleistocene: A Reevaluation, Shubhabrata Paul

USF Tampa Graduate Theses and Dissertations

Previous study of drilling predation on the bivalve Chione during the late Neogene of Florida suggested that prey-size selectivity of predators was disrupted by species turnover and morphological change within the prey genus. More recent experimental work, however, showed that at least some of these changes can be attributed to the confounding effects of facies shifts between naticid-dominated, muricid-dominated, and mixed predator assemblages. As muricids have the most abundant and continuous fossil record and are most responsible for predation on the Chione bivalve in modern benthic ecosystems of Florida, we use new criteria to isolate the muricid component of the …

Microsphere-Aided Characterization Of Stimuli-Responsive Polymer Networks, Carlos A. Bello

USF Tampa Graduate Theses and Dissertations

The fabrication and characterization of surface-anchored hydrogel microstructures are described. The hydrogel structures are constructed from poly(N-isopropylacrylamide), or poly(NIPAAm), which is a well-known thermoresponsive polymer that swells and contracts with changes in temperature. When patterned on a surface, these structures can experience a variety of shape changes induced by nonuniform swelling. Depending on the aspect ratio, patterns can, for instance buckle upon swelling and form wave-like patterns. Such structural changes replicate oscillatory motion of the smooth muscle cells and can be used to transport objects in microfluidics. The work, herein, investigates methods of pattern production and introduces a new technique …

Aging With Identity: Integrating Culture Into Senior Housing, Christine Sanchez

USF Tampa Graduate Theses and Dissertations

There is an underlying hope that those whom are elderly can exist in a place of happiness, comfort, security and familiarity; and can do so by aging in a place which complies with an understanding of their needs as older adults. However, along with aging comes a negative association of dependence and deterioration. Therefore, it is intuitive to have a connection between both the aging process and the design process. Creating a product which brings a positive association with senior housing and aging in place is the underlying goal within the project and overall design.

With the increasing population of …

An Ethologically Relevant Animal Model Of Post-Traumatic Stress Disorder: Physiological, Pharmacological And Behavioral Sequelae In Rats Exposed To Predator Stress And Social Instability, Phillip R. Zoladz

USF Tampa Graduate Theses and Dissertations

Post-traumatic stress disorder (PTSD) is a debilitating mental illness that results from exposure to intense, life-threatening trauma. Some of the symptoms of PTSD include intrusive flashback memories, persistent anxiety, hyperarousal and cognitive impairments. The finding of reduced basal glucocorticoid levels, as well as a greater suppression of glucocorticoid levels following dexamethasone administration, has also been commonly observed in people with PTSD. Our laboratory has developed an animal model of PTSD which utilizes chronic psychosocial stress, composed of unavoidable predator exposure and daily social instability, to produce changes in rat physiology and behavior that are comparable to the symptoms observed in …

The Acquisition Of Procedural Skills: An Analysis Of The Worked-Example Effect Using Animated Demonstrations, David Lewis

USF Tampa Graduate Theses and Dissertations

While many educators suggest active, rather than passive learning, this is not always the best solution, especially when learners are novices. Sweller and Cooper found learners who passively studied worked examples were significantly more efficient than those who actively solved problems (Cooper & Sweller, 1987; Sweller & Cooper, 1985) later described as the "worked-example effect" (Sweller & Chandler, 1991).

The current study tested the claims of Lewis (2005) who suggested animated demonstrations act as worked examples. It compared the performance of groups of preservice teachers who: studied animated demonstrations (demo); studied animated demonstrations and practiced procedures (demo+practice & demo2+practice), or …

The Virtual Landscape Of Geological Information Topics, Methods, And Rhetoric In Modern Geology, Sarah Elizabeth Fratesi

USF Tampa Graduate Theses and Dissertations

Geology is undergoing changes that could influence its knowledge claims, reportedly becoming more laboratory-based, technology-driven, quantitative, and physics- and chemistry-rich over time. This dissertation uses techniques from information science and linguistics to examine the geologic literature of 1945-2005. It consists of two studies: an examination of the geological literature as an expanding network of related subdisciplines, and an investigation of the linguistic and graphical argumentation strategies within geological journal articles.

The first investigation is a large-scale study of topics within articles from 67 geologic journals. Clustering of subdiscipline journals based on titles and keywords reveals six major areas of geology: …

Socializing Housing Phased Early Response To Impromptu Migrant Encampments In Lima, Peru, Raul E. Mayta

USF Tampa Graduate Theses and Dissertations

Every year hundreds of people migrate from the highlands of Peru to the coastal capital of Lima searching for economic and social stability. These groups of people have similar characteristics that keep them together they come from the same city, are members of the same family, have the same religion, have similar goals, and so on. Once in Lima they take possession of the only free areas left in the city: the mountains. Due to a lack of economic resources, poor urban planning and unsuitable site conditions the settlements grow for years in a disorderly, unsafe and unsanitary way, creating …

Talking With Exotic Pet Owners: Exploratory Audience Research On Wildlife Television And Human-Animal Interactions, Susannah L. Smith

USF Tampa Graduate Theses and Dissertations

This qualitative grounded study explores the potential relationship between wildlife TV viewing and human-animal interactions for exotic pet owners. The method involved 13 in-depth interviews and a qualifying open-ended questionnaire with 37 individuals. The interviews gathered viewers' interpretations of two different human-wildlife interactions on TV and served as a launching point for discussion. Findings supported the literature in that wildlife TV was an important source of information, emotion, and contradictory messages. Themes also emerged regarding participants' characterizations of their relationships with their pets. Drawing from social cognitive theory, this thesis suggests the following potential motivators for participants to model animal …

Eco_Urbanism Restitching Clearwater's Urban Fabric Through Transit And Nature, Daniel P. Uebler

USF Tampa Graduate Theses and Dissertations

Downtown Clearwater has grown to be disconnected from its surroundings due to an adjacent buffer area and the lack of a transit system to bring people into the city. The downtown core is also separated from its neighboring residential areas by an area of vacant land that holds in it the potential to become a gateway into the city. On a macro scale the city has grown to be separated from the Tampa Bay area due to the lack of a mass transit system.

The goal of this project is to create a new "new urbanism" in which transit and …

Protecting The Self: An Ethnographic Study Of Emotion Management Among Child Protective Investigators, Aaron Christopher Howell

USF Tampa Graduate Theses and Dissertations

The question that I investigate here is what emotion work is performed by child protective investigators in order to be successful at their work, and how do they manage these emotional challenges within a community of their peers? Many different workers, from airline employees (Hochschild, 1983) to mortuary science students (Cahill, 1999) to 911 operators (Shuler & Sypher, 2000), have been studied to examine strategies and effects of emotion management. Yet scholars do not agree on whether emotion management at work is positive or negative.

For my research, I conducted interviews with ten investigators and observed a night unit of …
