Ground-Coupled Air Waves: A Seismological Case Study Of The Explosion Quakes Of The 2007 Eruption Of Pavlof Volcano, Alaska, Cassandra Marie Smith

USF Tampa Graduate Theses and Dissertations

An abnormally high number of explosion quakes were noted during the monitoring effort for the 2007 eruption of Pavlof Volcano on the Alaskan Peninsula. In this study we manually counted the explosion quakes from their characteristic ground-coupled air waves. This study makes an effort at better quantifying the number of explosion quakes and how the characteristic ground-coupled air waves are affected by wind direction and wind speed. Additionally this study investigates how the ground coupled air waves might be used in a monitoring or analysis effort by calculating energy release and gas mass release. Over 3.2x10⁴ quakes were recorded. …

Population Dynamics Of The Little Gulper Shark (Centrophorus Uyato) And Community Analyses Of Elasmobranch Species In The Northern Gulf Of Mexico, Jacquelin Joye Hipes

USF Tampa Graduate Theses and Dissertations

In chapter 1 I describe the population dynamics of an understudied species of gulper shark, Centrophorus uyato (common name, the Little Gulper), found in the Northern Gulf of Mexico. Sharks in the family Centrophoridae are mid-sized, demersal fish, with seven species identified in North American waters. These deepwater species can be difficult to study due to the extreme depths at which they occur. During four longlining cruises from 2012-2014, 593 sharks were landed, predominantly in the Mississippi Canyon off the Louisiana coast. Mean depth of capture was 290 m. Supplementing these data are catch records for C. uyato from a …

Comparison Of Gastropod Assemblages From Natural And Phosphate Mine Lakes Of Central Florida, William A. Mailand

USF Tampa Graduate Theses and Dissertations

Investigations were made examining the relationships between gastropod species richness and abundance across 20 phosphate and 20 natural lakes in Central Florida. In additional to lake category, age of phosphate lakes was used to determine if phosphate lakes ever approximate natural lakes. Additional physical, chemical, and biological parameters, including chlorophyll a, Ca, secchi, phosphorous, conductance, fish predation, and recreational lake use were investigated in order to determine if they affected gastropods with lake age. Comparisons were also made between gastropod species richness and average abundance and two groups of dominant vegetation categories: Panicum, a structurally complex macrophyte, and Typha …

Tell Sir Thomas More We've Got Another Failed Attempt: Utopia And The Burning Man Project, Gracen Lila Kovacik

USF Tampa Graduate Theses and Dissertations

Burning Man, a weeklong experience in Black Rock Desert, Nevada, has become an oasis for those looking to escape the corporatized grasp of modern culture. Burning Man serves as a reprieve from judgment and allows participants to embrace and perform their inner identities. The intensions of Burning Man have been widely debated, from scholars concentrating on the rejection of consumerism to analyzing sacred space and religious connectivity for festivalgoers. What deserves further analysis, however, is the utopian nature of the event. I will explore previous utopian attempts--literary, political, etc.--and define what characteristics from those societies were present during the inception …

Multiple Stain Histology Of Skeletal Fractures: Healing And Microtaphonomy, John Wellington Powell

USF Tampa Graduate Theses and Dissertations

The forensic examination of wounds is one of the key elements of analysis performed by forensic anthropologists and forensic pathologists. Gross examination and histological analysis can be used to determine the timing of the wound and its cause. While forensic pathologists are trained to analyze hard and soft tissue wounds, forensic anthropologists, bioarchaeologists, and paleopathologists, focus on hard tissue. Forensic anthropologists have the added benefit of potentially working with residual soft tissue and would benefit from the incorporation of microscopy techniques that take advantage of the soft tissue to better understand perimortem events. Little research has been published that examines …

Ecological Sanitation In Uganda: Promotion Through Demonstration Facilities And Potential For Ascaris Reduction By Free Ammonia Inactivation Using Stored Urine, John Thomas Trimmer

USF Tampa Graduate Theses and Dissertations

As Uganda works to transform itself into an industrialized, middle-income country in the coming decades, the country is faced with a number of problematic trends that could hinder this transition. High population growth and urbanization are quickly forcing small towns to deal with issues of limited space and the aesthetic conditions within sanitation systems, while declining soil fertility in surrounding rural areas calls into question the future nutritional security of the growing population. Ecological Sanitation (Eco-San) systems, which are designed to recover nutrients from human excreta, may help to address these trends.

Improved sanitation coverage in Uganda is currently estimated …

Sexual Functioning And Body Image In Younger Breast Cancer Survivors, Carly Lynn Paterson

USF Tampa Graduate Theses and Dissertations

Younger breast cancer survivors often report problems related to sexuality following surgical and adjuvant treatment that often lead to sexual distress and body image distress. This research was conducted as an exploratory study within a larger R01 trial with the purpose to evaluate sexual distress and body image related-distress in younger women with breast cancer and to examine the extent to which the Mindfulness-Based Stress Reduction-Breast Cancer (MBSR(BC)) was efficacious in improving distress related to sexuality, i.e. sexual distress and body image related-distress. The aims of this study were to: 1) evaluate the efficacy of the MBSR(BC) program in improving …

Silicone Elastomer-Based Combinatorial Biomaterial Gradients For High Throughput Screening Of Cell-Substrate Interactions, Greeshma Mohan

USF Tampa Graduate Theses and Dissertations

Biomaterials have evolved over the years from the passive role of mere biocompatibility to an increasingly active role of presenting instructive cues to elicit precise responses at the molecular and cellular levels. Various characteristics common to synthetic biomaterials in vitro and extracellular matrices in vivo, such as immobilized functional or peptide groups, mechanical stiffness, bulk physical properties and topographical features, are key players that regulate cell response. The dynamics in the cell microenvironment and at the cell adhesive interface trigger a web of cell-material and cell-cell information exchanges that have a profound impact in directing the ultimate cell fate …

A Framework For Determining Building Water Cycle Resilience Using A Dynamic Water Resilience Assessment Model (Wram), Caryssa Joustra

USF Tampa Graduate Theses and Dissertations

The aim of this project was to quantitatively measure the resilience of the building water cycle. In order to accomplish this goal, a framework was developed that outlines how building water resilience can be evaluated. The framework presented assumed that resilience describes the fulfillment of system functions; in this case, the system functions considered are those actualized by the building water system. A building water resilience assessment model (WRAM) was developed with the ability to simulate different building water cycles and resilience scenarios. Resilience is dependent on the type and magnitude of a disturbance. Therefore, unique disruption scenarios were developed …

Analytics And Healthcare Costs (A Three Essay Dissertation), Lina Bouayad

USF Tampa Graduate Theses and Dissertations

Both literature and practice have looked at different strategies to diminish healthcare associated costs. As an extension to this stream of research, the present three paper dissertation addresses the issue of reducing elevated healthcare costs using analytics. The first paper looks at extending the benefits of auditing algorithms from mere detection of fraudulent providers to maximizing the deterrence from inappropriate behavior. Using the structure of the physicians' network, a new auditing algorithm is developed. Evaluation of the algorithm is performed using an agent-based simulation and an analytical model. A case study is also included to illustrate the application of the …

Hpv Vaccine Decision-Making Among Male Sexual Minorities: An Integrative Theoretical Framework For Vaccine Promotion, Christopher W. Wheldon

USF Tampa Graduate Theses and Dissertations

Men who have sex with men (MSM) are at increased risk of anal cancer as a result of anal HPV infection. Routine HPV vaccination is recommended for all MSM up through age 26; however, vaccine uptake among this population is low. The Integrative Model of Behavioral Prediction (IM) was used to identify, describe, and explain psychosocial factors related to HPV vaccine decision-making for young MSM. A sequential mixed-methods approach consisting of semi-structured interviews, a quantitative survey, and a qualitative open-ended survey was used to address the following aims: (1) Determine salient outcome, normative, efficacy, and control beliefs related to HPV-vaccination …

Fabrication Of Tissue Precursors Induced By Shape-Changing Hydrogels, Olukemi O. Akintewe

USF Tampa Graduate Theses and Dissertations

Scaffold based tissue reconstruction inherently limits regenerative capacity due to inflammatory response and limited cell migration. In contrast, scaffold-free methods promise formation of functional tissues with both reduced adverse host reactions and enhanced integration. Cell-sheet engineering is a well-known bottom-up tissue engineering approach that allows the release of intact cell sheet from a temperature responsive polymer such as poly-N-isopropylacrylamide (pNIPAAm). pNIPAAm is an ideal template for culturing cell sheets because it undergoes a sharp volume-phase transition owing to the hydrophilic and hydrophobic interaction around its lower critical solution temperature (LCST) of 32°C, a temperature close to physiological temperature. Compared to …

A Comparative Evaluation Of The Learner Centered Grading Debriefing Method In Nursing Education, Marisa J. Belote

USF Tampa Graduate Theses and Dissertations

The nursing discipline lacks a consensus on a best practice method for debriefing students following simulation-based training. A recognized, standardized method does not exist and various methods are utilized within the domain. The similarities between aviation and healthcare are well documented. Training members of both disciplines require standardization and methods of best practice. The aviation industry through the Federal Aviation Administration has found Learner Centered Grading (LCG) to be a successful educational format. The utilization of the LCG Debriefing method in simulation-based training is the standardized debriefing format for a technologically dynamic industry.

The aim of this research was to …

Validity Testing Of A Preschool Reading Screening Device For Pediatricians, Erika Elaine Blue

USF Tampa Graduate Theses and Dissertations

Despite efforts to improve access to early literacy intervention in the United States, there are still children entering kindergarten that are not adequately prepared for school and are unlikely to catch up to their peers (National Education Association, 2014). Preschool programs are actively involved in screening their students for potential literacy difficulties; however, there are children who do not attend preschool and may not have their literacy development assessed. One solution to this problem is to involve other individuals who routinely see preschool age children. Pediatricians are one such group as children come to them for their wellness visits and …

Robust, Low Power, Discrete Gate Sizing, Anthony Joseph Casagrande

USF Tampa Graduate Theses and Dissertations

Ultra-deep submicron circuits require accurate modeling of gate delay in order to meetaggressive timing constraints. With the lack of statistical data, variability due to the mechanical manufacturing process and its chemical properties poses a challenging problem. Discrete gate sizing requires (i) accurate models that take into account random parametric variation and (ii) a fair allocation of resources to optimize the solution. The proposed GTFUZZ gate sizing algorithm handles both tasks. Gate sizing is modeled as a resource allocation problem using fuzzy game theory. Delay is modeled as a constraint and power is optimized in this algorithm. In GTFUZZ, delay is …
