Evolution And Functional Morphology Of The Cephalic Lobes In Batoids, Samantha Lynn Mulvany

USF Tampa Graduate Theses and Dissertations

Cephalic lobes are unique structures derived from the anterior pectoral fins, found in select myliobatid stingrays. Many benthic batoids utilize undulatory locomotion and use their pectoral fins for both locomotion and prey capture. Pelagic myliobatids that possess cephalic lobes utilize oscillatory locomotion, using their pectoral fins to locomote and their cephalic lobes for prey capture. Despite differences in habitat usage and locomotor modes, these batoids feed on very similar benthic organisms. The purpose of this study was to 1.) compare the morphology of the cephalic lobes and anterior pectoral fins in lobed and lobeless species, looking at skeletal elements, musculature …

Using Habit Reversal To Decrease Filled Pauses And Nervous Habits In Public Speaking, Carolyn Joanne Mancuso

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Public speaking is a challenge faced by people from all walks of life. Research in the area of public speaking has focused on examining techniques to reduce public speaking anxiety. Very little research, however, has focused on the acquisition of public speaking skills. While presenting speeches, many people engage in nervous habits that have the potential to decrease the effectiveness of the speech and their credibility as a speaker. This study evaluated the effectiveness of simplified habit reversal in reducing three of these nervous habits: filled pauses, tongue clicking, and inappropriate use of the word like. Following baseline, participants …

An Exploration Of Threatened Harm As A Type Of Maltreatment And Its Relation To Recurrence Of Maltreatment, Roxann Mcneish

USF Tampa Graduate Theses and Dissertations

There were no studies found in the literature that primarily focused on threatened harm as type of maltreatment. This study utilized Florida's child welfare administrative data to explore threatened harm as a type of maltreatment, particularly as a predictor of recurrence of maltreatment within six and 12 months for children who had a verified report of maltreatment in FY2005-2006. Threatened harm was examined in three ways; when it was reported as the only maltreatment, the initial maltreatment, and in situations where there was a prior report. The most prevalent acts of threatened harm were examined separately. It was examined as …

Contrast Adaptation In The Lateral Eye Of Limulus Polyphemus, Tchoudomira Valtcheva

USF Tampa Graduate Theses and Dissertations

Luminance and contrast adaptation are neuronal mechanisms that the retina applies for continuous adjustment to light sensitivity though a collection of cellular and synaptic mechanisms distributed across the retinal network, thus accommodating the wide input range of the visual system within the constricted output range of retinal ganglion cells. Luminance mean adaptation has been demonstrated in the output neurons of the invertebrate eye (eccentric cells), and the aim of the study was to investigate whether the homology in visual processing extends to luminance variance (contrast) adaptation as well. The spike trains of individual eccentric cells were recorded from live horseshoe …

Factors Influencing Vaccination Decisions In African American Mothers Of Preschool Age Children, Chauntel Mckenzie Mcnair

USF Tampa Graduate Theses and Dissertations

Rates and coverage levels of immunizations of African-American children are reduced compared to other races. Few studies have identified factors that influence vaccination decisions of African-American mothers. This study assessed the mothers' vaccination decisions using a self-administered questionnaire and a screening instrument for determining health literacy. This instrument is called Rapid Estimate of Adult Literacy in Medicine (REALM). The sample was 92 African American mothers, recruited from a large metropolitan church in Jacksonville, Florida, who had at least one child under the age of seven. A cross-sectional research design was used to administer survey instruments to identify and interpret parental …

A Three Dimensional Scaffold For Anticancer Drug Development, Yvonne Girard

USF Tampa Graduate Theses and Dissertations

Attrition rates for anticancer drugs are much higher than any other therapeutic area. Only 5%#37; of the agents that demonstrate anticancer activity in the preclinical stages of development demonstrate clinical efficacy in phase III trials. This high attrition rate becomes alarming when we consider that the cost of research and development can amount to 1 billion dollars. To exacerbate this problem, many new cancer drugs are being discontinued, withdrawn or suspended. The reasons for this high attrition rate are complex and may be partly attributed to suboptimal preclinical strategies such as the use of two-dimensional (2D) cell culture systems to …

Referral Tracking Pilot And Referral Outcome Rates For The School Health Program In Panama, Jesica Eileen Candanedo

USF Tampa Graduate Theses and Dissertations

Background: The School Health Program (SHP) in the Republic of Panama includes preventive healthcare services delivery and referral issuing at elementary schools nationwide. Despite these early prevention efforts, a majority of referrals are apparently not achieving their desired outcome. This idea is supported by the SHP data showing preventable diseases on the rise. Thus, learning the outcome rates of particular referral outcomes may provide a basis for appropriately targeted action.

Methods: Three focus groups were conducted with health workers, medical records staff, and teachers, respectively. Following systems thinking and framework analysis, a pilot plan for referral tracking and referral outcome …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to explore patients' perception and knowledge regarding hypertension and hypertensive guidelines on sodium intake and lifestyle modifications in a work environment in the Republic of Panama. Hypertension is important not only because of its high prevalence but also because it is a major modifiable risk factor for cardiovascular diseases. In Panama the prevalence of hypertension is about 38.7% and uncontrolled hypertension is almost 50%.This number may translate into complications for the general population. For instance 52.8% of the population has had an ischemic disease and death by ischemic disease climbed from third place to …

African Americans And Hospice: A Culture-Centered Exploration Of Disparities In End-Of-Life Care, Patrick Dillon

USF Tampa Graduate Theses and Dissertations

As the United States' population ages and grows more diverse, scholars and practitioners have grown increasingly concerned about persistent disparities in the cost and quality of end-of-life health care, particularly with regard to African Americans. Although a variety of factors may influence these disparities, most scholars agree that the underutilization of hospice care by this population is an important contributor. Drawing from the culture-centered approach to health communication and narrative theory, the present study explores African American patients and caregivers' experiences with hospice care and takes an initial step toward addressing disparities in end-of-life care. I begin this study, first, …

Universal Tumor Screening For Lynch Syndrome: Identification Of System-Level Implementation Factors Influencing Patient Reach, Deborah Le Cragun

USF Tampa Graduate Theses and Dissertations

Lynch syndrome (LS) is the most prevalent cause of hereditary colorectal cancer (CRC) and confers high risks for several other types of cancer. Universal tumor screening (UTS) of all newly diagnosed patients with CRC can improve LS identification and decrease associated morbidity and mortality among patients and family members. However, for UTS to be effective, patients who screen positive must pursue genetic counseling and confirmatory germline testing (i.e., high patient reach). The purposes of this study were to characterize UTS programs, identify barriers and facilitators to implementation, document whether there have been negative outcomes, and determine institutional and implementation conditions …

Toxoplasma gondii is an intracellular parasite that is common in the Middle East and has been reported to cause changes in personality and behavior.

The purpose of the current study was to examine relationships between T. gondii antibody titer and socioeconomic variables, dysphoric moods, and risk-taking behaviors in a sample of 70 female veterans. Blood samples were collected and analyzed for T. gondii antibody titer and …

Cost Of Treatment Of Asthma Attacks In A Tertiary Level Healthcare Hospital In Panama, Nydia Flores Chiari

USF Tampa Graduate Theses and Dissertations

Asthma is a chronic respiratory disease characterized by inflammation of the airway and the presence of recurrent attacks (exacerbations) of breathlessness, wheezing, cough, chest tightness, or some combination of these symptoms. In the US, about 53% of people with asthma had an asthma attack in 2008, and 57% of these, were children. One in ten children (10%) had asthma in 2009, and boys were more likely than girls to have asthma. Internationally, the prevalence of asthma varies widely in different countries, but the disparity is narrowing due to rising prevalence in low and middle income countries. Unfortunately, we do not …

The Water Culture Beliefs Of Embera Communities And Maternal And Child Health In The Republic Of Panama, Ilenia Anneth Forero

USF Tampa Graduate Theses and Dissertations

Water has cultural and spiritual values to indigenous people. These beliefs expose them to unsafe water sources and make them vulnerable to waterborne diseases. This background is not taken into account when countries write their water legislations, therefor imposing a management of water not readily accepted by them. The Embera group is one of the indigenous groups from the Republic of Panama, who have strong water beliefs. They live along the shore of rivers in houses built on high stilts away from urban areas. The purpose of this cross-sectional community based study is to describe through a survey the relation …

Prevalence, Predictors, And Correlates Of Patient Concealment Of A Lung Cancer Diagnosis, Brian David Gonzalez

USF Tampa Graduate Theses and Dissertations

Most cases of lung cancer have a commonly-understood behavioral etiology. Thus, individuals with lung cancer are often blamed for their illness by others and may therefore seek to avoid this blame by concealing their diagnosis from others. This study sought to determine the prevalence of diagnosis concealment, examine potential predictors of concealment, and test parts of a cognitive-affective-behavioral model of the effects of concealing a concealable stigma among individuals receiving treatment for lung cancer. With regard to predictors of concealment, it was hypothesized that concealment would be positively associated with male gender, introversion, and trait social anxiety and would be …

Exploring The Relationship Between Physical Activity And Everyday Cognitive Function In Older Adults: Within- And Between- Person Variability, Christine Haley

USF Tampa Graduate Theses and Dissertations

Research suggests that physical activity may play a role in preserving cognitive function in older adulthood. However, the exact nature, direction, and magnitude of observed associations remain unclear. The current study utilized a microlongitudinal design to repeatedly assess cognitive function and physical activity across five days. Two studies examined relationships between physical activity, physical fitness, and cognitive function among community-dwelling older adults. The first study examined associations between baseline performance in a measure of everyday cognition and multiple measures of physical activity and physical fitness. Bivariate analyses revealed that objectively measured physical activity of moderate-to-vigorous intensity, repeated chair stand time …

Supply Chain Optimization Of Blood Products, Serkan Gunpinar

USF Tampa Graduate Theses and Dissertations

Major challenges in the management of blood supply chain are related to the shortage and wastage of the blood products. Given the perishability characteristics of blood which can be stored up to a limited number of days, if hospitals and blood centers keep an excessive number of blood units on inventory, wastages may occur. On the other hand, if sufficient number of blood units are not stored on inventory, shortages of this resource may cause the cancellations of important activities and increase the fatality rates at hospitals. Three mathematical models have been developed with the goal to improve the efficiency …

Evaluation Of Pulmonary Risks Associated With Selected Occupations, Stephen Casey Harbison

USF Tampa Graduate Theses and Dissertations

Occupational health surveillance programs are designed to evaluate and reduce injury, illness, and deaths related to workplace hazards. In the state of Florida, there are numerous industries where workers are potentially exposed to airborne hazards from gases, vapors and dusts. Airborne occupational exposures to irritants, vesicants, and fibrogens have the potential to cause pulmonary function impairment if exposures are not properly controlled for high-level acute exposure as well as chronic exposure. For occupations that demand workers be exposed to substances known to be associated with pulmonary function impairment, respirators may be a principal method for exposure

control. OSHA requires pulmonary …

The Relationship Between High School Coaches' Beliefs About Sports Injury And Prevention Practice Readiness, Siwon Jang

USF Tampa Graduate Theses and Dissertations

Although sports and other forms of physical activities are associated with numerous health benefits, adolescent sports injury has emerged as an important public health problem. As the most immediate caregivers for athletes, coaches are expected to play an important role in preventing and reducing injuries, -considering that sports medical staff, such as athletic trainers are not always available to care for athletes. However, research on coaches' beliefs and practices related to injury prevention has been limited to coaching competency issues, in which injury prevention is considered only one component. Therefore, the purpose of the study was to describe the coaches' …

The Translational Machinery As A Target For Radiosensitization, Thomas John Hayman

USF Tampa Graduate Theses and Dissertations

Current approaches aimed at improving the efficacy of radiation as a cancer treatment modality involve the development and application of molecularly targeted radiosensitizers, a strategy that requires a thorough understanding of the fundamental processes comprising the cellular radioresponse. Recent data indicating that radiation modifies gene expression primarily through translational control rather than transcriptional events suggests that mRNA translation contributes to cell survival after irradiation. The overall goal of this project is to determine whether the regulatory/rate-limiting components of the translational machinery provide targets for tumor cell radiosensitization. The majority of translation in mammalian cells occurs in a cap-dependent manner and …

Evaluating The Effectiveness Of A Tablet Application To Increase Eye Contact In Children Diagnosed With Autism, Tricia Jeffries

USF Tampa Graduate Theses and Dissertations

Studies have shown that increasing eye contact can be accomplished by using reinforcement, prompting, shaping, functional movement training, punishment, and self-monitoring. However, there is a lack of research that evaluates the use of technology as a way to increase eye contact. This study tested the effectiveness of a tablet application at increasing eye contact in children diagnosed with autism. The application requires the child to look at a picture of a person's face and identify the number displayed in the person's eyes in order to receive reinforcement. Data was collected immediately after training, one hour after training, and in the …

Does The Use Of Personally Relevant Stimuli In Semantic Complexity Training Facilitate Improved Functional Communication Performance Compared To Non-Personally Relevant Stimulus Items Among Adults With Chronic Aphasia?, Stephanie Karidas

USF Tampa Graduate Theses and Dissertations

This study investigated the influence of semantic complexity treatment in individuals with fluent aphasia on discourse performance. Semantic treatment is an effective way to improve semantically based word retrieval problems in aphasia. Treatment focused on the semantic application of the Complexity Account of Treatment Efficacy (CATE) (Thompson, Shapiro, Kiran, & Sobecks, 2003) promotes training of complex items resulting in generalization to less complex, untrained items. In addition, research has shown that the personal relevance of treatment material can increase treatment efficacy. This study investigated the effect of semantic treatment of atypical personally relevant items among individuals with aphasia on discourse …

The Role Of Acquired Capability As A Differentially-Specific Risk Factor For Disordered Eating And Problematic Alcohol Use In Female College Students: A Measure Development And Validation Study, Christa D. Labouliere

USF Tampa Graduate Theses and Dissertations

Traditional college students are members of an age bracket noted for high levels of risky behavior, and research has shown that certain risky behaviors, such as disordered eating and problematic alcohol use, are particularly common among undergraduates. It is well established that certain events in the learning history predispose vulnerable persons to engage in maladaptive risky behaviors. What is less clear is why some persons facing these events go on to develop maladaptive behavior while others do not, or why people facing similar events develop different varieties of maladaptive behaviors. Current research has focused extensively on risk factors that are …

The Experiences Of Mothers Of Children With Autism In Jamaica: An Exploratory Study Of Their Journey, Angela R. Mann

USF Tampa Graduate Theses and Dissertations

Autism Spectrum Disorders (ASDs), also referred to as Pervasive Developmental Disorders (PDDs), are characterized by deficits in verbal and nonverbal communication, social interaction, and repetitive or restricted interests and behaviors. To date, much of the literature on ASDs has been conducted from a western perspective, although interest in ASDs from a global perspective has dramatically increased in recent years. Over the last decade, there have been numerous conceptual papers attempting to explain how autism might be experienced in other parts of the world. However, in actuality, little research has been conducted in this area, and further exploration of the experiences …
