Playing-With The World: Toy Story's Aesthetics And Metaphysics Of Play, Jonathan Hendricks
Playing-With The World: Toy Story's Aesthetics And Metaphysics Of Play, Jonathan Hendricks
USF Tampa Graduate Theses and Dissertations
Pixar’s Toy Story (John Lassiter, 1995) is not just a story about toys and the children that play with them, but a demonstration of how we interact with the world. This thesis looks at the way in which both main children, Andy and Sid, interact with their toys and how this interaction is one that is structured by way of what Martin Heidegger calls “Enframing.” In this modality of playing, toys and other things and entities in the world, and the world itself, appear to the children as on-hand resources for use at any time and can be molded, as …
Zonation Pattern And Spatial Arrangement Of A Geukensia Granosissima Population In A Mixed Mangrove Forest Of Tampa Bay, Derrick Shane Hudson
Zonation Pattern And Spatial Arrangement Of A Geukensia Granosissima Population In A Mixed Mangrove Forest Of Tampa Bay, Derrick Shane Hudson
USF Tampa Graduate Theses and Dissertations
Here I provide the first report on Geukensia granosissima patterns of abundance along a tidal gradient within a mixed mangrove stand located in Tampa Bay, Florida, USA. Specifically, I examined 1) the relationship between G. granosissima size and density with mangrove root type (e.g. prop root, pneumatophore), and of density within the intertidal zones; and 2) the possible role of predation in shaping the lower zonation patterns displayed. Transect surveys located along the lower and upper population limit boundaries were conducted every two months over a ten-month period. Variables measured include size distribution, density of mussels, above ground mangrove prop …
A Novel Abi-Domain Protein Controls Virulence Determinant Production In Staphylococcus Aureus, Stephanie Michelle Marroquin
A Novel Abi-Domain Protein Controls Virulence Determinant Production In Staphylococcus Aureus, Stephanie Michelle Marroquin
USF Tampa Graduate Theses and Dissertations
A major factor in the success of Staphylococcus aureus as a pathogen is its vast arsenal of virulence determinants and, more importantly, the tight and precisely- timed regulation of these factors. Here we investigate the product of the S. aureus gene, SAUSA300_1984, encoding a putative transmembrane protein. This as yet uncharacterized protein belongs to the Abi (abortive infection) family, which are commonly annotated as CAAX-proteases, and are significantly understudied in prokaryotes. In S. aureus the disruption of SAUSA300_1984 results in a drastic reduction of proteolytic and hemolytic activity, as well as diminished pigmentation. This phenotype appears to be mediated through …
Consistency Of Structural Color Across Molts: The Effects Of Environmental Conditions And Stress On Feather Ultraviolet Reflectance, Rebecca Lynn Windsor
Consistency Of Structural Color Across Molts: The Effects Of Environmental Conditions And Stress On Feather Ultraviolet Reflectance, Rebecca Lynn Windsor
USF Tampa Graduate Theses and Dissertations
Across avian systems, plumage ornamentation is often considered a signal of individual fitness, condition, sex, or status, and varies due to genetics or environmental sources. In species with structural coloration, plumage variation results from differences in the amount of energy allocated to feather growth during molt, presenting a unique opportunity to study the link between individual quality and ornamentation. In cooperative breeding species, such as the Florida Scrub-Jay (Aphelocoma coerulescens), the role of structural color as a signal is particularly important because helpers may delay breeding for one to several years and competition for space is high. Florida Scrub-Jay juveniles …
Land Use, Stream Stability, And Benthic Invertebrates In A Dry Forest Watershed Of Western Costa Rica, Jacqueline Ann Demko
Land Use, Stream Stability, And Benthic Invertebrates In A Dry Forest Watershed Of Western Costa Rica, Jacqueline Ann Demko
USF Tampa Graduate Theses and Dissertations
There is a paucity of data on dry forests, the most threatened biome in the tropics. The Nandamojo is a tropical dry forest watershed in Western Costa Rica that has been impacted by varying degrees of human induced modifications. This research was conducted to examine the influence of land use and channel characteristics on invertebrate communities within a sub basin of the Nandamojo watershed. This study addressed three hypotheses: (1) sites with low tree cover and small riparian buffer zones will have high erosion, (2) macroinvertebrate abundance will be lower at sites with low channel stability values, and (3) benthic …
Mechanisms Of Ikbke Activation In Cancer, Sridevi Challa
Mechanisms Of Ikbke Activation In Cancer, Sridevi Challa
USF Tampa Graduate Theses and Dissertations
Cancer is the second leading cause of death in the USA and it is expected to surpass heart diseases making it important to understand the underlying mechanisms of cancer. The efforts to target single signaling molecule showed little success in increasing the patient survival and it can be due to increased compensation for cell survival by alternative pathway activations. Hence comprehensive understanding of the alternative signaling pathways may help us treat cancer better. Chronic inflammation is attributed to increased risk of cancer and emerging studies show the growing importance of both canonical and non-canonical IκB kinases such as IKKα, IKKβ, …
Changing The Pathobiological Paradigm In Myelodysplastic Syndromes: The Nlrp3 Inflammasome Drives The Mds Phenotype, Ashley Basiorka
Changing The Pathobiological Paradigm In Myelodysplastic Syndromes: The Nlrp3 Inflammasome Drives The Mds Phenotype, Ashley Basiorka
USF Tampa Graduate Theses and Dissertations
Note: Portions of this abstract have been previously published in the journal Blood, Basiorka et al. Blood. 2016 Oct 13, and has been reproduced in this manuscript with permission from the publisher.
Myelodysplastic syndromes (MDS) are genetically diverse hematopoietic stem cell malignancies that share a common phenotype of cytological dysplasia, ineffective hematopoiesis and aberrant myeloid lineage maturation. Apoptotic cell death potentiated by inflammatory cytokines has been considered a fundamental feature of MDS for over two decades. However, this non-inflammatory form of cell death cannot account for the inflammatory nature of these disorders. We report that a hallmark of lower-risk …
