Determining Potential Uptake Pathways Of Persistent Organic Pollutants And Heavy Metals In Jobos Bay National Estuarine Research Reserve, Puerto Rico, Ashley Huber
USF St. Petersburg campus Master's Theses (Graduate)
Fiddler Crab (U. rapax) tissue, mangrove tissue and sediment from crab burrows were collected in Jobos Bay National Estuarine Research Reserve, Puerto Rico, to quantitate Persistent Organic Pollutants (OCs, PCBs, PBDEs) and selected heavy metals (cadmium, barium, mercury, lead, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic and selenium). Once quantified, the concentrations were applied to a bioconcentration factor equation to determine potential uptake pathways of the target analytes. Bioconcentration factors determined that fiddler crabs were the most efficient at concentrating OC pesticides, while mangroves were the most efficient at concentrating PCBs and heavy metals.
Mangrove Encroachment Into Ecologically Restored Salt Marshes: Quantifying Vegetative And Soil Carbon In Tampa Bay, Florida, Emma E. Dontis
Mangrove Encroachment Into Ecologically Restored Salt Marshes: Quantifying Vegetative And Soil Carbon In Tampa Bay, Florida, Emma E. Dontis
USF St. Petersburg campus Master's Theses (Graduate)
Coastal wetlands are one of the world's most productive and valuable ecosystems. Mangrove forests, salt marshes, and salt barrens are the dominant coastal wetlands in the Tampa Bay estuary. These "blue carbon" sinks absorb carbon dioxide and store organic carbon (OC) in their vegetation and underlying sediments, allowing them to partially mitigate climate change. However, the global areal extent of these ecosystems has declined by 25-50%, so restoring critical coastal wetland habitats has become imperative. Created coastal wetlands in the Tampa Bay area are first planted with salt marsh vegetation, but often transition into mangrove forests, a process known as …
The Effects Of Binaural Beats On Emotion And Cognition, Olivera Petrovich
The Effects Of Binaural Beats On Emotion And Cognition, Olivera Petrovich
USF St. Petersburg campus Master's Theses (Graduate)
When two tones of similar frequencies are presented in each ear, the brain responds by perceiving a third tone, known as a binaural beat. Binaural beat technology is marketed as a self-improvement tool to reduce stress, improve mood, increase cognition, deepen meditation, and alter states of consciousness. The purpose of this study is to explore the effects of binaural beats with delta and theta frequencies to determine if these changes can improve mood and creativity using a pre- and post-test experimental design. Participants completed the Positive Affect and Negative Affect Schedule (PANAS) to measure mood by identifying how closely they …
Do Spoilers Change A Person's Enjoyment Of A Television Show?, Olivia M. Leal
Do Spoilers Change A Person's Enjoyment Of A Television Show?, Olivia M. Leal
USF St. Petersburg campus Master's Theses (Graduate)
Previous research has demonstrated that story spoilers - explaining how a story ends before the person has had a chance to discover it themselves - can either make the story more enjoyable or less enjoyable. This study examined the potential moderating effects of individual differences regarding need for cognition and need for affect. In this study, participants complete 2 individual difference measures and watched an episode of TI1e Twilight Zone. Participants were randomly assigned into one of four conditions: spoiler and explicit, no spoiler and explicit, spoiler and not explicit, no spoiler and not explicit. There was no effect found …
Mos2 Doped Tio2 Nanomaterial And The Enhancement Of Photocatalytic Properties For Solar Disinfection, Timothy Mccolgan
Mos2 Doped Tio2 Nanomaterial And The Enhancement Of Photocatalytic Properties For Solar Disinfection, Timothy Mccolgan
USF St. Petersburg campus Master's Theses (Graduate)
This research project focused on the synthesis, characterization, and environmental application of a photocatalytic nanomaterial composed of molybdenum (IV) disulfide [MOS2] doped titanium dioxide [TiO2]. Extensive research has been conducted on the electronic uses of nanocrystalline MoS2 as a phototransistor and absorptive species (Yin et al., 2012), as well as the photocatalytic effects of TiO2 (Diebold, 2003). Research has also been performed into the generation of oxidizers from TiO2 nanocomposites (Zhang et al., 2015), but as of yet no research has been conducted on a practical application of this material. This project fills that void by evaluating its effectiveness while …

Free Speech And Defamation In Kuwait And U.S. Law: Historical Dimension Of Jurisdictions And Law In A Social Context, Ahmad Shehab Alshehab
Free Speech And Defamation In Kuwait And U.S. Law: Historical Dimension Of Jurisdictions And Law In A Social Context, Ahmad Shehab Alshehab
USF St. Petersburg campus Master's Theses (Graduate)
This legal comparative study aims to explore how the U.S. and Kuwaiti legal formants, such as legislators and judges, achieve balance with individuals' reputational rights and freedom of speech and the press. It also examines the factors contributing to their differing views about defamation and free speech limitations. The law-in-context method and the Theory of Legal Formants were applied to achieve the study objectives. Traditional, religious, and historical factors have made significant impacts on Kuwaiti laws. The results show some contradiction between the laws as written, as interpreted, and as applied in the country. The first step in reforming these …

Factors Affecting Hiv Testing Among Youth In Kenya, Allison Nall
Factors Affecting Hiv Testing Among Youth In Kenya, Allison Nall
USF St. Petersburg campus Master's Theses (Graduate)
With the high prevalence of HIV among youth in sub-Saharan Africa, it is vital to better understand factors affecting HIV testing among this population; this is the first step in the HIV treatment cascade. Using existing data from the SEERs (Stigma-reduction via Education, Empowerment, and Research) Project, a community-based participatory research program targeting 13-24 year olds in Kenya, the purpose of this study was to examine factors related to behavioral intentions regarding HIV testing. It was hypothesized that HIV knowledge, social support, subjective well-being, and mental health would serve as facilitators to HIV testing while projected stigma and substance use …
Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern
Spatial And Temporal Levels Of Microplastics In Tampa Bay Surface Waters, Laurinda Kinsley Mceachern
USF St. Petersburg campus Master's Theses (Graduate)
This study focused on collecting microplastics in Tampa Bay estuarine surface waters in order to identify temporal and spatial differences. While there have been many studies of microplastic contamination in the marine environment over the past decade, quantifying microplastics in urban estuaries is constrained. This study provides an understanding of the abundance, distribution, and composition of microplastics at twenty sites in Tampa Bay as well as four ancillary tributary stations. The objectives of the study were to identify how surrounding land use type, freshwater sources, seasonal changes in precipitation, and wastewater treatment plant discharge affect microplastic concentrations. Water samples were …
Soil Accumulation, Accretion, And Organic Carbon Burial Rates In Mangrove Soils Of The Lower Florida Keys: A Temporal And Spatial Analysis, Amanda R. Chappel
Soil Accumulation, Accretion, And Organic Carbon Burial Rates In Mangrove Soils Of The Lower Florida Keys: A Temporal And Spatial Analysis, Amanda R. Chappel
USF St. Petersburg campus Master's Theses (Graduate)
This study compared the temporal variability in rates of soil accumulation, accretion, and organic carbon (OC) burial from three sites in the Lower Florida Keys using two different radiometric dating techniques (210Pb, 14C). Comparison of these rates across various timescales (decadal, centurial, and millennial) permitted examination of temporal responses and drivers. Further, spatial variability was measured for these associated site rates. Differences in geographic location and site morphologies as predicted, were supported by spatial variability in all rates across sites with the exception of centurial rates of accretion. All rates were greater when assessed over shorter (e.g. decadal) timescales. The …
