Investigation Of Sediment Ridges Using Bathymetry And Backscatter Near Clearwater, Florida, Lewis Stewart

USF Tampa Graduate Theses and Dissertations

Changes in sediment morphology on the West Florida Shelf is investigated over a 14-year time period using multibeam bathymetry and backscatter in water depths between 10 m and 20 m, off the coast of Indian Rocks Beach, Pinellas County, Florida. Bathymetric surveys collected in 2002 (Kongsberg EM 3000 at 300 kHz) and 2016 (Reson 7125 at 400 kHz) were processed using CARIS Hips and Sips to create bathymetric maps and backscatter images. These data were then interpreted and compared in order to test hypotheses and answer questions related to sediment migration and sediment volume change.

The following questions prompted this …

Characterizing Benthic Habitats Using Multibeam Sonar And Towed Underwater Video In Two Marine Protected Areas On The West Florida Shelf, Usa, Jennifer L. Brizzolara

USF Tampa Graduate Theses and Dissertations

This study investigates a way to characterize the geology and biology of the seafloor in two Marine Protected Areas on the West Florida Shelf. Characterization of benthic habitats needs to include sufficient detail to represent the complex and heterogeneous bottom types. Characterizations can be interpreted from multiple data sets and displayed as benthic habitat maps. Multibeam sonar bathymetry and backscatter provide full spatial data coverage, but interpretation of such data requires some form of ground truth (to characterize the habitat). Imagery from towed underwater video provides continuous transects of seafloor data, which provide a more efficient method than data from …

Alba As Eternal Mother: Violent Spaces And The ‘Last Woman’ In Manuel De Pedrolo’S "Mecanoscrit Del Segon Origen", Pedro Nilsson-Fernàndez

Alambique. Revista académica de ciencia ficción y fantasía / Jornal acadêmico de ficção científica e fantasía

The ambitious literary project of Catalan author Manuel de Pedrolo i Molina (1918-1990) has generally been perceived as belonging to the tradition of popular literature, a label often reinforced by the unprecedented success of his minor work Mecanoscrit del segon origen. This has clearly damaged Pedrolo’s status in the Catalan literary; as Kathryn Crameri highlights, “(w)hen authors such as Manuel de Pedrolo championed more popular genres such as crime fiction” –or science fiction as far as this study is concerned– “they had to endure criticisms of the quality of their writing” (Crameri, 2008, p. 23). This article will challenge …

Geospatial And Negative Binomial Regression Analysis Of Culex Nigripalpus, Culex Erraticus, Coquillettidia Perturbans, And Aedes Vexans Counts And Precipitation And Land Use Land Cover Covariates In Polk County, Florida, Joshua P. Wright

USF Tampa Graduate Theses and Dissertations

Although mosquito monitoring systems in the form of dry-ice bated CDC light traps and sentinel chickens are used by mosquito control personnel in Polk County, Florida, the placement of these are random and do not necessarily reflect prevalent areas of vector mosquito populations. This can result in significant health, economic, and social impacts during disease outbreaks. Of these vector mosquitoes Culex nigripalpus, Culex erraticus, Coquillettidia perturbans, and Aedes vexans are present in Polk County and known to transmit multiple diseases, posing a public health concern. This study seeks to evaluate the effect of Land use Land cover …

Longitudinal Awareness: A Study Of Vulnerability To Flooding In Polk County, Iowa, Kerri A. Dickey

USF Tampa Graduate Theses and Dissertations

Flooding has become a problem of national proportion and many scholars have started to take note of the human impacts in this area. This study will focus on the social vulnerability framework in tandem with the environmental justice theoretical frameworks being applied to Polk County Iowa so that information can be added to the body of works within a Midwestern U.S. context. This research will contribute to the current geographical knowledge in natural hazards, environmental justice, and vulnerability to flood hazards. Taking into consideration the scarcity of county or sub-county studies in the Midwest U.S. measuring spatial tendencies in hazards …

3d Cave And Ice Block Morphology From Integrated Geophysical Methods: A Case Study At Scărişoara Ice Cave, Romania, Jackson Durain Hubbard

USF Tampa Graduate Theses and Dissertations

Scărişoara Ice Cave has been a catalyst of scientific intrigue and effort for over 150 years. These efforts have revealed and described countless natural phenomena – and in the process have made it one of the most studied caves in the world.

Of especial interest is the massive ice block located within its Great Hall and scientific reservations. The ice block, which is the oldest and largest known to exist in a cave, has been the focus of multiple surveying and mapping efforts, typically ones utilizing traditional equipment. In this study, the goals were to reconstruct the ice block/cave floor …

Testing The Medical Arms Race Hypothesis: A Spatial Approach, Robyn M. Kibler

USF Tampa Graduate Theses and Dissertations

The surgical robot experienced rapid uptake throughout hospitals in the US despite lack of clinical evidence that it is superior to existing methods and undeterred by its high cost. This type of technology may be a “weapon” in the medical arms race hypothesis which asserts that competition among hospitals may be welfare reducing wherein it encourages resource use that is not commensurate with beneficial health outcomes. This paper is a case-study of the diffusion of the surgical robot among hospitals in Florida. We address the medical arms race hypothesis directly by investigating whether a hospital’s decision to adopt a robot …
