Fate Of Polybrominated Diphenyl Ethers During Wastewater Treatment Process Producing Reclaimed Water, Kristy Siegel

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs), flame retardants, have been applied to consumer goods, such as furniture, electrical devices, textiles, and appliances for decades. Due to their physico-chemical properties, PBDEs are semi-volatile and easily leach off the consumer good during aging, stress, or normal wear and tear of the good. Once airborne, they pose an environmental health threat because they can adsorb onto dust particles, soil, or other particulates that can be inhaled, ingested, or come into contact with the dermal layer. Additionally, PBDEs have a molecular structure similar to other persistent organic pollutants, such as polychlorinated biphenyls and polychlorinated dibenzo-p-dioxins and …

Polybrominated Diphenyl Ethers In Sediments Within The Hillsborough Bay Watershed, Candice Simmons

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs) are a widely used class of flame retardants that are important sources for contamination in the marine environment. Sediments serve as a large reservoir for PBDEs due to their large sorption capacity. This research assessed the presence and distribution of PBDEs in Hillsborough Bay, a subdivision of Tampa Bay, FL, by determining levels in surface sediment samples, creating a historical profile of the contaminant in a sediment core taken from within the bay, and investigating sediment characteristics that control their distribution. Compositional patterns and temporal distributions of 8 of the 209 congeners of PBDEs (BDE-28, -47, …

Development Of A Confirmatory Pcr Assay To Detect Onchocerca Volvulus In Pools Of Vector Black Flies, Alex Jeanne Talsma

USF Tampa Graduate Theses and Dissertations

Onchocerciasis, or river blindness, has historically represented one of the significant neglected tropical diseases on the planet in terms of socio-economic impact. The discovery that ivermectin was a safe and effective treatment for onchocerciasis, together with the decision of the manufacturer to donate the drug for the treatment of this disease became the basis for several large international programs to control and eventually eliminate the infection. These programs have managed to virtually eliminate transmission of the parasite causing Onchocerca volvulus from many foci in Africa and the Americas. Verifying that transmission has been halted requires sensitive and specific assays to …

Examination Of The Relationship Of Community College Opticianry Student Outcomes With Instructional Delivery Method And Student Age, William Brent Underwood

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine whether student outcomes are a function of participation in different modes of delivery in an Opticianry program at the community college level. First, the intent was to determine whether differences in instructional delivery methods and background characteristics impact student performance in an Opticianry program. The three instructional delivery methods were traditional face-to-face instruction, online delivery, and a hybrid format where students take theory courses online and attend face-to-face laboratories on campus. A second objective was to determine the role of background variables such as student age, which was the age when entering …

Development Of An Investigator-Designed Questionnaire Concerning Childbirth Delivery Options Based On The Theory Of Planned Behavior, Chun-Yi Tai

USF Tampa Graduate Theses and Dissertations

This study responds to the globally increasing rate of caesarean section, and specifically to the very high rate of elective caesarean section among Taiwanese mothers as evidence suggests that such elective caesareans pose potential health risks for mothers and babies. The purpose of this study was to develop and evaluate a multi-component instrument based on the theory of planned behavior (TPB) to better understand Taiwanese pregnant women's decisions regarding their childbirth delivery options (spontaneous vaginal delivery or elective caesarean section). The study was a four-phased mixed method design. First, the TPB guided item development and instrument drafting. Second, pretesting and …

Complete Genome Sequences And Phylogeny Of West Nile Virus Isolates From Southeastern United States, 2003-2012, Crystal Wedin

USF Tampa Graduate Theses and Dissertations

The study of the evolution and phylogeny of West Nile virus (WNV) has been an important area of research since the introduction of WNV in 1999. However, genome sequencing of isolates from the Southeastern part of the United States has been somewhat limited. To determine how WNV has evolved at a more localized level, ten isolates from Florida and Georgia from 2003-2012 were completely sequenced using Illumina's next-generation technology. In addition, a phylogenetic comparison of both the complete genome and select partial genomes was completed to ensure consistency among the results. This study further demonstrated the dominance of the North …

Chlorophyll Fluorescence And Thermal Stress In Archaias Angulatus (Class Foraminifera), Heidi M. Toomey

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Benthic foraminifers that host algal symbionts are similar to corals in that they rely on their algal endosymbionts for their energy needs, calcify prolifically, and are sensitive to changes in environmental conditions. They are abundant in the benthos of coastal coral-reef areas and are found throughout the tropical and subtropical regions. Pulse Amplitude Modulated (PAM) chlorophyll fluorometry and chlorophyll a extraction techniques were used to quantify and compare the photosynthetic responses of the benthic foraminiferal, Archaias angulatus and their isolated endosymbionts, Chlamydomonas hedleyi, to short-term changes in temperature. Maximum quantum efficiency (F_v/F_m) and rapid …

Influence Of Maternal Thyroid Dysfunction On Infant Growth And Development, Ronee Elisha Wilson

USF Tampa Graduate Theses and Dissertations

Thyroid dysfunction is one of the most common endocrine disorders in women of childbearing age and the obstetric consequences of abnormal thyroid hormone levels during pregnancy have been established. Less understood is the implication of the presence of maternal thyroid autoantibodies on infant outcomes among women who are euthyroid during pregnancy. The objective of this study was two-fold: 1) to examine the influence of antenatal thyroperioxidase (TPO) status on fetal/infant brain and body growth measurements at delivery and 2) to explore the relationship of antenatal TPO status and maternal postpartum thyroid dysfunction (PPTD) on early infant growth and neurocognitive development. …

Predation, Competition, And Nutrient Levels Affect The Survival Of Escherichia Coli, Enterococci And Enteric Pathogens In Aquatic Habitats, Pauline Wanjugi

USF Tampa Graduate Theses and Dissertations

Fecal indicator bacteria (FIB) such as Escherichia coli and enterococci are used to assess microbiological water quality in recreational waters worldwide. FIB are used with the assumption that their presence correlates with that of fecal-associated pathogens in recreational waters. In aquatic habitats, several factors can interfere with the predictive relationship between FIB and pathogens including extended survival of FIB in secondary habitats such as sediment, vegetation and sand. Furthermore, many biotic (e.g. predation from bacterivorous protozoa and competition from indigenous bacteria) and abiotic factors (e.g. temperature, salinity, ultraviolet (UV) light irradiation, and nutrient availability) can influence the fate of FIB …

Improving Implementation Of A Regional In-Line Chlorinator In Rural Panama Through Development Of A Regionally Appropriate Field Guide, Benjamin A. Yoakum

USF Tampa Graduate Theses and Dissertations

Access to safe drinking water has a direct effect on improving human health and their quality of life. One country still struggling with providing access to safe drinking water to all of its population is Panama. Panama's largest indigenous group, the Ngöbe people, is disproportionately affected by lack of access to safe drinking water. One way Panama's Ministry of Health (MINSA) is attempting to increase access to safe drinking water to the Ngöbe people is by disinfecting the water already captured by rural gravity fed water systems constructed within in the Ngöbe-Bugle reservation. This is accomplished using an in-line chlorinator …

Synoptic To Interannual Variability In Volumetric Flushing In Tampa Bay, Fl Using Observational Data And A Numerical Model, Monica Wilson

USF Tampa Graduate Theses and Dissertations

This research provides insight into changes in volumetric flushing of the Tampa Bay estuary caused by synoptic scale wind events. The two main studies of this dissertation involve 1) using wavelet analysis to investigate the link between the El Niño-Southern Oscillation (ENSO) and the frequency and strength of volumetric flushing driven by synoptic variability and 2) using a multi-decadal model simulation to examine how extratropical/winter storms and hurricanes affect the overall flushing rates for Tampa Bay, FL.

In the first study, two analyses are performed on 55 years of observational data to investigate the effect of multiple small wind events …

High-Frequency Stimulation Of Nucleus Accumbens Changes In Dopaminergic Reward Circuit, Na Yan, Ning Chen, Honghua Zhu, Jianguo Zhang, Moira Sim, Yu Ma, Wei Wang

Research outputs 2013

Deep brain stimulation (DBS) of the nucleus accumbens (NAc) is a potential remedial therapy for drug craving and relapse, but the mechanism is poorly understood. We investigated changes in neurotransmitter levels during high frequency stimulation (HFS) of the unilateral NAc on morphine-induced rats. Sixty adult Wistar rats were randomized into five groups: the control group (administration of saline), the morphine-only group (systematic administration of morphine without electrode implantation), the morphine-sham-stimulation group (systematic administration of morphine with electrode implantation but not given stimulation), the morphine-stimulation group (systematic administration of morphine with electrode implantation and stimulation) and the saline-stimulation group (administration of …

Generational Differences And Fly-In-Fly-Out (Fifo) Employee Turnover, Pattanee Susomrith, Alan R. Brown, Glenda B. Scott, Helen B. Sitlington

Research outputs 2013

Fly-in, fly-out (FIFO) mining has experienced significant growth in the past decade and is now a typical form of employment in the sector in Australia. Evidence suggests that there are relatively high turnover levels amongst these employees. Whilst there are many contributing causes to this, there may be variances between different generational cohorts at work as arguably their workplace expectation differs. This paper investigates whether turnover intentions vary between different generations of employees. Using a questionnaire, employees were asked about their turnover intentions and this was compared against the groups of Baby Boomers, Generation X and Generation Y. Findings show …

Using Research Informed Approaches To Strategic Hrm Teaching, Alan J. Coetzer, Helen B. Sitlington

Research outputs 2013

This paper outlines research that was guided by the broad question: What teaching and learning (T&L) strategies should be employed in SHRM? This question was answered using data gathered in three focus groups involving T&L specialists, business strategy and HRM academics, and HRM practitioners. Through a process of successive focusing, potential T&L strategies were initially identified and then tested and refined in the focus groups. Drawing on literature and input from the participants, we contend that SHRM can be effectively taught through a combination of primarily problem-based and case-based approaches. We also argue that process worksheets are an effective method …

Could On-The-Job Embeddedness Help Bind Fifo Workers To Their Jobs?, Glenda B. Scott, Helen B. Sitlington, Pattanee Susomrith, Alan R. Brown

Research outputs 2013

Fly-In Fly-Out (FIFO) employees in the mining industry in Western Australia have had high levels of turnover, resulting in high costs in recruitment, training and lost production. This research is seeking to understand the reasons for high turnover in this somewhat unusual group of employees. Whilst the research has utilised the more traditional approach to understanding labour turnover, that is that dissatisfaction with job or company and the availability of viable alternatives lead to intention to quit, preliminary results indicate that job embeddedness theory, may provide a better understanding of why FIFO workers choose to stay in their jobs. This …

Nutritional Narratives: Cultural And Communications Perspectives On Plant-Based Diets, Julie S. Dare, Leesa N. Costello, Lelia R. Green

Research outputs 2013

This paper responds to a range of popular materials circulating in the public sphere asserting a plant-based (PB) diet is of benefit to humans and a protection against many chronic diseases. Although directed at a lay audience, books such as The China Study (Campbell & Campbell) are based upon extensive academic research, and highlight multiple health, environmental and social advantages of PB diets over traditional western diets. Arguments advocating PB nutrition, however, generally struggle to achieve traction in the public sphere. Narratives around PB food choices, and difficulties in shifting mainstream eating patterns, reflect the cultural symbolism attached to food, …
