Modeling And Parameter Study Of Bistable Spherical Compliant Mechanisms, Chester Smith

USF Tampa Graduate Theses and Dissertations

The bistable spherical compliant mechanism (BSCM) is a novel device capable of large, repeatable, out-of-plane motion, characteristics that are somewhat difficult to achieve with surface micromachined microelectromechanical systems. An improved pseudo-rigid-body model (PRBM) to predict the behavior of the BSCM is presented. The new model was used to analyze seven different versions of the device, each with a different compliant joint length. The new model, which adds torsion, is compared with a finite element analysis (FEA) beam model. The new model more closely approximates the results yielded by FEA than previous models used to analyze the BSCM. Future work is …

Evolution/Creationism Controversy: Analysis Of Past And Current Policies In Public Schools And The Practice Of Allowing Students To Opt-Out Of Learning Evolution Concepts, Jacquelyn Hoffmann Speake

USF Tampa Graduate Theses and Dissertations

Recent anti-evolution legislation, in the form of Academic Freedom bills, has been introduced in many state legislatures over the last three years. The language in the proposed Academic Freedom bills may allow different interpretations of what can be taught in the science classrooms, and possibly spur parents to take advantage of their perceived parental rights to request their child be opted-out of class when the scientific theory of evolution is taught. Five research questions guided the analysis of participant responses to questions and perception statements focusing on secondary school administrators' actions, perceptions, and awareness as they relate to their decision …

Perspective Shifting In Relative Clauses By Elementary-Aged Spanish-English Bilinguals: A Cross-Linguistic Study, Xigrid Tayri Soto

USF Tampa Graduate Theses and Dissertations

Language-specific theories of sentence processing suggest that individuals interpret sentences based on the characteristics of their native language (e.g., Bates & MacWhinney, 1989). As such, competing linguistic cues are taken into account (including word order, morphology, and animacy) and the cue selected is most likely to yield a correct interpretation in the native language. However, research in this area has produced conflicting results. MacWhinney (2005) has proposed that examining the role of perspective shifting in sentence comprehension may demonstrate how cognitive and syntactic factors work together to facilitate sentence comprehension. The aim of the current study is to investigate the …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

El Poder / The Power: Latino/A Literature Inclusion In The Florida High School Language Arts Classroom As A Contributing Deterrent To The Latino/A Dropout Rate, Monica Adriana Sleeter

USF Tampa Graduate Theses and Dissertations

Curricula throughout the country, specifically in the School District of Hillsborough County (SDHC), do not encompass diverse subject matter as it relates to Latino/a students. The primary argument posed in this thesis is that consistent engagement to Latino/a writings in the English language arts classroom can be a positive force that contributes to an increased rate of retention of Latino/a youths in high school and a higher percentage of Latino/a high school graduates. This Latino/a literature can be in the form of supplementary reading material that teachers will have access to that will include Latino/a literature from various authors that …

Pilot Assessment Of Novel Membrane Bioreactor Processes - Improvements In Biological Nutrient Removal And Membrane Operation, Shaleena Smith

USF Tampa Graduate Theses and Dissertations

With increasing water reuse applications and upcoming stringent regulations for treated wastewater effluent discharge, wastewater plants need to consider alternative technologies beyond conventional treatment processes. The new regulations, Numeric Nutrient Criteria (NNC), may regulate discharge nitrogen and phosphorus concentrations to as low as 0.5 mg/L as N and 10 μg/L as P respectively. To meet these target requirements, system retrofitting to incorporate chemical or advanced nutrient removal systems possibly with membrane technology will most likely be required. Although microfiltration/ultrafiltration membranes coupled with biological processes, otherwise known as membrane bioreactors (MBR), remove contaminants and suspended solids, nutrient removal is minimal to …

USF Tampa Graduate Theses and Dissertations

Spanish Indian is a generic term that has been used repeatedly in written documents over the past three centuries to describe a range of different social, ethnic, and economic groups in the southeastern United States. In this thesis, a comparative analysis of the material culture from Cuban fishing ranchos of the eighteenth and nineteenth centuries on the west coast of Florida addresses the ways in which specific Spanish Indian artifact assemblages fit into the archaeological record. Three archaeological assemblages from known Rancho sites are detailed and analyzed. In addition, this thesis details a public archaeology project undertaken in conjunction with …

Predictors Of Body Dissatisfaction, Eating Disturbance, And Depressive Symptoms In Mothers, Steffanie Sperry

USF Tampa Graduate Theses and Dissertations

Body image, eating disturbance, and depressive symptomatology have been examined extensively in the general population. The assessment of these variables within the postpartum period has also been a target of recent research. Unfortunately, no existing studies have examined the intercorrelations among these factors in mothers of young children, despite increasing media pressure for moms to maintain a slim, pre-pregnancy body. The current study examined predictors of body dissatisfaction, eating disturbance, and depressive symptoms in mothers of children aged 0-5. Simple correlations were followed by a series of linear multiple regressions incorporating sociocultural predictors alongside covariates identified in the extant literature. …

National Identity, Gender, And Genre: The Multiple Marginalization Of Lotte Reiniger And The Adventures Of Prince Achmed (1926), K. Vivian Taylor

USF Tampa Graduate Theses and Dissertations

Contemporary American visual culture is saturated with animation, from websites and advertisements to adult and children's television programs. Animated films have dominated the American box office since Toy Story (1995) and show no signs of relenting, as demonstrated by Up (2009) and Alice in Wonderland (2010). Scholarly interest in animation has paralleled the steady rise of the popularity of the medium. Publications addressing animation have migrated from niche journals, such as such as Animation Journal and Wide Angle, to one of the most mainstream English-language publications, the Modern Language Association's Profession, which included Judith Halberstam's article "Animation" in …

Growing Up With Hiv: Disease Management Among Perinatally Infected Adolescents, Barbara J. Szelag

USF Tampa Graduate Theses and Dissertations

Children born with HIV in the 1980s and 1990s are surviving into adolescence and adulthood, due to the availability of highly active antiretroviral therapy (HAART). Growing up with a chronic and stigmatized disease presents considerable challenges as young people explore their sexuality, develop relationships, and take steps to become independent and productive adults. Adherence to HAART is an essential and life-long practice for the maintenance of health and longevity. For adolescents born with HIV, a daily medication schedule is one aspect of disease management that also includes medical visits, HIV status acceptance, bouts of illness, and disclosure of HIV status …

Asymmetric Passive Dynamic Walker Used To Examine Gait Rehabilitation Methods, John Sushko

USF Tampa Graduate Theses and Dissertations

Testing gait rehabilitation devices on humans can be a difficult task, due to the effects of the neurological controls of the human body. This thesis advances the use of a passive dynamic walker (PDW) tuned to have asymmetric gait patterns similar to those with physical impairments to test rehabilitation devices. A passive dynamic walker is a multipendulum system that has a stable gait pattern when walking down a slope without any energy inputs except the forces due to gravity. A PDW model is better suited for testing rehabilitation devices because it has been shown to resemble human gait and separates …

Sisters In Arms: A Case Study Of The Experiences Of Women Warriors In The United States Military, Carmen Teresa Stein-Mccormick

USF Tampa Graduate Theses and Dissertations

Presently there are few studies that describe the current experiences of women warriors relative to issues such as sexual hostility, sexual harassment, and other uncommon experiences during their military careers. Very little is known about how being a woman in a male-dominated military may affect women warriors' choices between making the military a career or returning to civilian life. With better understanding of women warriors' military experiences, mental health professionals, educators, and other human services professionals may have a better understanding of the issues that may affect women in the military. To date there are limited studies that have examined …

Indicators Of Early Adult And Current Personality In Parkinson's Disease, Kelly Sullivan

USF Tampa Graduate Theses and Dissertations

Introduction: Previous epidemiologic studies suggest that the personality of Parkinson's disease (PD) patients differs from that of controls, and laboratory evidence supports a potential common pathophysiology of personality traits and PD. One nested case-control study found that PD cases were significantly more anxious than controls before the clinical onset of the disease, and additional data suggest that certain occupations may be risk factors for the disease. Additionally, the latent period that precedes the onset of motor symptoms of PD is unknown.

Objectives: The objectives of this study were to evaluate the association of PD with objective indicators of current and …

The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman

USF Tampa Graduate Theses and Dissertations

This paper describes a sequence of experiments addressing basic questions about the control of visual attention and the relationship between attention and object recognition. This work reviews compelling findings addressing attentional control on the basis of high-level perceptual properties. In five experiments observers were presented with a rapid sequence of object photographs and instructed to either detect or selectively encode a verbally cued object category. When these object categories (e.g. "baseball") were preceded by contextual images associated with a given object category (e.g. "baseball diamond"), observers were less likely to accurately report information about the target item. This effect obtained …

Patient Safety In Nursing Homes, Kali Thomas

USF Tampa Graduate Theses and Dissertations

Safety of residents has gained increased popularity in recent years following a report from the Institute of Medicine attributing 98,000 hospital deaths each year to errors by staff. As a result, regulatory agencies, advocates, and health care providers have shifted their focus to understanding patient safety and developing a culture that promotes safety. However, nursing homes lag behind other health care providers in their adoption of a patient safety culture and understanding what factors affect safety in resident care. These insights are needed to ensure that nursing home residents receive the safe care.

Drawing upon 20 in-depth interviews with second generation Haitian young adults, I examined the ethnic identities and the involvement in ethnic organizations of the respondents. This study pays particular attention to how involvement in ethnic organizations influenced how the second generation Haitians believed the earthquake affected their identities and how they ultimately responded to the earthquake. Several of the findings revealed differences in how and why the respondents chose to ethnically identify such as Haitian, Haitian-American, black Haitian. The respondents' choice to join an ethnic organization was driven by different desires but the perceived influence of the organization on their …

The Abjection Of The Pythia, Alaina Dyann Tackitt

USF Tampa Graduate Theses and Dissertations

Recent academic research has garnered considerable popular interest on the matter of whether the Pythia, the Oracle of Delphi, was high. Current findings aim to prove that vapors emitted from beneath the tripod on which the Pythia prophesied were intoxicating, thereby causing her frenzied state and statements. Contemporary scientists’ intense interest in proving that the Pythia was not prophetic evokes the question of why the once widely accepted, now generally rejected, idea that a female body can serve as a vessel for the words of the immortal deity holds such significance for modern science. When this curiosity is considered in …

People In Between: The Value Of Life Stories In Exploring The Needs Of Colombian Asylum Seekers, Poonam R. Valliappan

USF Tampa Graduate Theses and Dissertations

The long, protracted civil war, spanning nearly fifty years, in the South American nation of Colombia has displaced almost four million civilians in as much time. Tens of thousands of refugees were resettled in Ecuador, Panama, Venezuela and other neighboring countries. Some, still threatened in their country of first asylum, and resettled to the United States (US) with their families, must learn to navigate the often complex systems of life and living in America. Resettlement programs that focus primarily on immediate needs such as employment and accommodations are aware of the growing need for more long&ndashterm assistance. However, while there …

A Comparison Of Latina Women In Centeringpregnancy And Individual Prenatal Care, Tara E. Trudnak

USF Tampa Graduate Theses and Dissertations

CenteringPregnancy is a model of group prenatal care that replaces routine, individual prenatal care. The program brings women together into small groups to receive their care and prenatal education, and is based on three components: risk assessment, education, and support. The model is client-centered, designed to empower pregnant women and support persons, and involves the woman in small group discussions of 8-10 other women of similar gestational age. The group discussions provide support, help women educate each other, and invoke self-monitoring. Currently, there have been few publications that closely examined maternal weight and obesity and associated outcomes in women involved …

The Role Of Brca1 Domains And Motifs In Tumor Suppression, Aneliya Velkova

USF Tampa Graduate Theses and Dissertations

Individuals that carry deleterious mutations in the breast and ovarian cancer susceptibility gene 1 (BRCA1) have much more elevated risk to develop breast and/or ovarian cancer than the individuals from the general population. The BRCA1 gene product has been implicated in several aspects of the DNA damage response, but its biochemical function in these processes has remained elusive. In order to probe BRCA1 functions we conducted a yeast two-hybrid screening to identify interacting partners to a conserved motif (Motif 6) in the central region of BRCA1. In this dissertation, we report the identification of the actin-binding protein Filamin A (FLNA) …

A Discrete-Continuous Modeling Framework For Long-Distance, Leisure Travel Demand Analysis, Caleb Van Nostrand

USF Tampa Graduate Theses and Dissertations

This study contributes to the literature on national long-distance travel demand modeling by providing an analysis of households' annual destination choices and time allocation patterns for long-distance leisure travel purposes. An annual vacation destination choice and time allocation model is formulated to simultaneously predict the different destinations that a household visits and the time it spends on each of these visited destinations, in a year. The model takes the form of a Multiple Discrete-Continuous Extreme Value (MDCEV) structure (Bhat, 2005; Bhat, 2008). The model assumes that households allocate their annual vacation time to visit one or more destinations in a …

Despite the plethora of information regarding cellular crowding and its importance on modulating protein function the effects of confinement on biological molecules are often overlooked when investigating their physiological function. Recently however, the encapsulation of biomolecules in solid state matrices (NafionTM, sol-gels, zirconium phosphate,etc.) has increased in importance as a method for examining protein conformation and dynamics in confined space as well as novel applications in biotechnology. Biotechnological applications include, but are not limited to, bioremediation, biosensors, biocatalysts, etc. In order to better utilize solid state materials as substrates for biological molecules an understanding of the effects of encapsulation on …

Modeling Direct Runoff Hydrographs With The Surge Function, Denis Voytenko

USF Tampa Graduate Theses and Dissertations

A surge function is a mathematical function of the form f(x)=ax^pe^-bx. We simplify the surge function by holding p constant at 1 and investigate the simplified form as a potential model to represent the full peak of a stream discharge hydrograph. The previously studied Weibull and gamma distributions are included for comparison. We develop an analysis algorithm which produces the best-fit parameters for every peak for each model function, and we process the data with a MATLAB script that uses spectral analysis to filter year-long, 15-minute, stream-discharge data sets. The filtering is necessary to locate the …
