Locating, Characterizing, And Comparing Submerged Precontact Site Hubbard Spring To Other Submerged Spring Sites Throughout Florida, Madison Day

USF St. Petersburg campus Honors Program Theses (Undergraduate)

The rise of sea level over the past 20,000 years has led to the submersion of nearly half of Florida’s original land mass, causing freshwater springs hypothesized to have been a gathering spot for prehistoric people to become submerged. As the water rose, humans lost touch with their ancestors’ ways of life and migratory patterns. In recent years, however, interests in the potential significant cultural, archeological, and paleontological resources at submerged spring sites on the West Florida Shelf have spiked among geo-archeologists, historical experts, biologists, and geologists.

The goal of the WF2305 research cruise aboard the R/V Western Flyer was …

Understanding Bicycle Signal Operations And Leading Bicycle Interval (Lbi) Implementations, Yaye Keita, Shubhankar Shindgikar

CUTR Internal Grant Research Program

Bikes are among the sustainable modes of transportation and bicycling can help decrease congestion, reduce emissions, and enhance health. Due to their numerous benefits, they are currently one of the promoted modes in the United States. Yet, bicyclists are vulnerable roadway users and are subject to safety concerns. The safety challenges faced by bicyclists are more evident when looking at serious crashes. Although only 1.9% of total crashes are bicycle related, bicycle crashes account for 5.6% of fatal crashes (Alluri et al., 2017).

For years, Florida has had the largest number of bicyclist fatalities in the nation. As a result, …

Klimchouk’S Impact On The Development Of Speleogenetic Models For Castile Evaporites: West Texas And Southeastern New Mexico, Usa, Kevin W. Stafford

International Journal of Speleology

Due to the pioneering work of Alexander Klimchouk (2007), hypogene karst is now recognized as being complex and extensive throughout Permian strata of the greater Delaware Basin in West Texas and southeastern New Mexico (USA). Klimchouk heavily influenced our current understanding of hypogene speleogenesis in the Permian Ochoan Castile Formation where we now recognize diverse hypogene manifestations that include vertically-extensive breccia pipes, laterally-extensive blanket breccias, morphologically-varied caves, diagenetically-altered sulfates, and unique venting structures. Underlying Bell Canyon strata provide the transmissive zone for delivery and removal of solutionally aggressive fluids to the conformably overlying Castile evaporites. Current speleogenetic models indicate that …

The Effect Of Fixed Time Delays On The Synchronization Phase Transition, Shaizat Bakhytzhan

USF Tampa Graduate Theses and Dissertations

Nature is full of synchronization phenomena, which are essential to many scientific fields like biology, chemistry, physics, and neuroscience. The Kuramoto model is a well-known theoretical model that helps explain the fundamental ideas behind synchronization dynamics [6]. Nevertheless, in practical situations, systems frequently display intrinsic latency, which can greatly impact their behavior during synchronization. This insight inspired our work, which looks at the results of adding temporal delays to the Kuramoto model. In particular, we investigate how the system’s synchronization dynamics are affected by delays. We shed light on the mechanisms underpinning synchronization in the face of temporal delays and …

Slot Machine Addiction: The Untold Story Of Contradictions Between Self And America's Neoliberal Risk Society, Melanie C. Falconer

USF Tampa Graduate Theses and Dissertations

The ability to take risks is nothing short of heroism in the modern United States which thrives on a diet of hyper mobility, technological progress, and globalized, deregulated “free” markets. Such relentless instability affirms scholarly contentions that the U.S. is now a “risk society.” Indeed, in Gambling with the Myth of the American Dream: The Pokerization of America, rhetoric scholar Aaron Duncan suggests that media stories of modern poker tournaments signify a collective desire to grapple with this heightened modern “chanciness” within our established gambling lore and make it cohere with our deeply cherished notions of American individualism. While Duncan …

A New Nature Is Coming. We Will Be Repossessed, And The Spectres Of The Post-Natural Will Take The World. Predictions Of A New Symbiotic Earth In "Fafner" (2018) By Daniel Perez Navarro, Miguel Angel Albújar-Escuredo

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

This paper engages in the debates about decentralizing the role of men in the world we live in. Byproducts of this new mindset are concepts such as the “Posthuman” (Braidotti 2012); the status of “Holobiont” (Haraway 2016), and the experiencing of a new “Coexistence” with the non-human (Morton 2018). I suggest the novel Fafner (2018) as a perfect sample of this intellectual debate from an artistic and fictional view. Using concepts from diverse fields of thinking and applying them to literary analysis, this paper will review the in-depth transformation of nature portrayed by Fafner’s narration. Additionally, it will accomplish …

A Republic Of Pawprints: The Rise And Reign Of The Alaskan Sled Dog, 1870-1970, Christopher David Adkins

USF Tampa Graduate Theses and Dissertations

This dissertation charts the career of the Alaskan sled dog: how it was used as an engine of development, how it became a symbol for early American Alaska, and how it fell victim to obsolescence as newer and faster means of conveyance became available. The figure of the sled dog in the Arctic is complex. Because it was closer to the wolf in phenotype both it, and Alaska, were buffeted by the same White settler expectations and Darwinian chauvinism which afflicted its Indigenous peoples. This would intensify during the baptisms by fire of the gold rushes. Dog abuse – overwork, …

Time-Scale Of Groundwater Recharge In Coastal Plain Soils, Qing Du

USF Tampa Graduate Theses and Dissertations

Understanding and modeling the timing and magnitude of groundwater recharge fromrainfall infiltration through vadose zone percolation is important for many reasons but especially because the flux is being acted on by root zone evapotranspiration (ET) and very little of rainfall infiltration ever becomes water table recharge. This study elaborates on the considerable time of the wetting front arrival and ultimate bulk recharge of rainfall infiltration in shallow water table fine-sandy soils typical of coastal plain environments such as Florida. Calibrated Hydrus-1D modeling of Florida (Myakka) soil was evaluated at varying depths of water table and hydraulic conductivities to bracket the …

Dispersion Of Artificial Tracers In Ventilated Caves, Claudio Pastore, Eric Weber, Frédéric Doumenc, Pierre-Yves Jeannin, Marc Lütscher

International Journal of Speleology

Artificial CO₂ was used as a tracer along ventilated karst conduits to infer airflow and investigate tracer dispersion. In the karst vadose zone, cave ventilation is an efficient mode of transport for heat, gases and aerosols and thus drives the spatial distribution of airborne particles. Modelling this airborne transport requires geometrical and physical parameters of the conduit system, including the cross-sectional areas, the airflow and average air speed, as well as the longitudinal dispersion coefficient which describes the spreading of a solute. Four gauging tests were carried out in one mine (artificial conduit) and two ventilated caves (natural conduits). …

Comparative Analysis Of Time Series Models On U.S. Stock And Exchange Rates: Bayesian Estimation Of Time Series Error Term Model Versus Machine Learning Approaches, Young Keun Yang

USF Tampa Graduate Theses and Dissertations

This study presents a comparative analysis of contemporary applications of time series models, focusing on the Bayesian approach. In contrast to many nonparametric studies, the Bayesian approach circumvents the common issue of bandwidth selection by offering systematic estimation and avoiding ad hoc methods. Specifically, we delve into the Bayesian approach for estimating the autocovariance function of a time series model’s error term. Traditional time series models often make the unrealistic assumption of a constant error term. Furthermore, models such as autoregressive conditional heteroskedasticity (ARCH) and general autoregressive conditional heteroskedasticity (GARCH) address the limitation of constant variance by assuming an autoregressive …
