A Geographic Information System For Dynamic Ridematching, Sasha Dos-Santos

USF Tampa Graduate Theses and Dissertations

The Online Transportation Option System (OTOS) is a Geographic Information System (GIS) that addresses many of the limitations associated with traditional dynamic ridematching applications. The main improvements are in the areas of trip scheduling and match searching. OTOS is unique in its ability to accept trips with schedules that can not be expressed in terms of a regular weekly trip. OTOS also distinguishes itself in its use of spatial analysis techniques to locate matches. Specifically, the use of a shortest path solver enables the ridematching algorithm to perform a search along the path of a user’s trip, in addition to …

Re-Engineering Graduate Medical Education: An Analysis Of The Contribution Of Residents To Teaching Hospitals Utilizing A Model Of An Internal Medicine Residency Program, Ian M. Elius

USF Tampa Graduate Theses and Dissertations

According to the Institute of Medicine (IOM), the U.S. health care delivery system does not provide consistent, high-quality medical care to all people all the time. As a significant component of the health care delivery system, the state of Graduate Medical Education in the United States has prompted much analysis in recent years due to the general view that desired and actua l outcomes are increasingly at variance with each other. One area of focus has been the implications of change for provider credentialing and funding of graduate medical education.

With this research we test the hypothesis that residents perform …

Hope And Quality Of Life In Hospice Patients With Cancer, Cynthia Brown

USF Tampa Graduate Theses and Dissertations

Hope is considered to have a positive influence upon health. Cancer patients may enter hospice care after a rigorous course of medical treatment, having hoped for a cure or long remission. While the hope for cure is important, hope is no less important at the end of life when the goal of care is quality of life. This study examined the relationship between hope and quality of life in hospice patients with cancer.

Thirty-one patients with cancer, who were alert, oriented, living with a caregiver, and aware of their diagnosis were sampled from a hospice program. The instruments used were …

The Relationship Between Caregiving And Bereavement: A Series Of Three Studies, Allison Burton

USF Tampa Graduate Theses and Dissertations

Spousal bereavement has been consistently demonstrated in the literature to be one of the most highly stressful experiences in an individual’s lifetime. In addition many deaths in the United States are preceded by a period of caregiving, which is also believed to be highly stressful and have a profound impact on bereavement. However the literature has been inconsistent as to the exact nature of the relationship between caregiving and bereavement and there has been some debate as to whether or not positive and negative affect variables are mutually exclusive.

This dissertation sought to further address the issue of the relationship …

The Impact Of Privatization Of Primary Care Programs In Large County Health Departments In Florida, Arlesia Lynn Brock

USF Tampa Graduate Theses and Dissertations

Since the mid-1970s, top managers, politicians, and officials in both public and private institutions have promoted contracting-out services (privatization) as a means of increasing efficiency, flexibility, and quality. The privatization trend has occurred in many public sector organizations particularly in city services and prisons. Public health services are not immune to this trend. Today many county health departments have contracted the provision of public health services like womens health, primary care, and laboratory services. However, very few studies have analyzed the impact of these privatizations on cost, access, and health outcomes. Proponents favoring the private provision of these services argue …

The Assessment Of Appearance Factors Related To Intentional Uv Exposure, Guy Cafri

USF Tampa Graduate Theses and Dissertations

Understanding the motives for sunbathing and indoor tanning is an extremely important public health issue. Skin cancer rates have increased dramatically in recent years and UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors. Motives for sunbathing and tanning salon use have been thought to be related to appearance concerns, yet little research has examined the specific tan appearance attitudes that may contribute to use of these behaviors. Two studies were conducted with the aim of assessing distinct attitudes related to a tan appearance. In the first study items were created based …

Distribution Of Clionid Sponges In The Florida Keys National Marine Sanctuary (Fknms), 2001-2003, Michael K. Callahan

USF Tampa Graduate Theses and Dissertations

In 2001, the Coral Reef Evaluation and Monitoring Program (CREMP) began monitoring the abundance and area covered by three clionid sponges (Cliona delitrix, C. lampa, and C. caribbaea). Subsequently, monitoring has been conducted annually at all 40 CREMP sites throughout the Florida Keys National Marine Sanctuary (FKNMS) and the Dry Tortugas. Between 2001 and 2002, mean clionid area decreased significantly from 7.6 cm2 /m2 to 4.6 cm2 /m2 (Wilcoxon; p= 0.035). Between 2002 and 2003, the decline to 4.5 cm2 /m2 was not significant. Approximately 80% of all clionid colonies recorded at the CREMP stations covered less than 50 cm2 …

Mapping The Major Axis Of Tephra Dispersion With A Mesoscale Atmospheric Model: Cerro Negro Volcano, Nicaragua, Marc A. Byrne

USF Tampa Graduate Theses and Dissertations

Models of tephra fallout are used to assess volcanic hazards in advance of eruptions and in near-real-time. Current models often approximate the wind field using simplistic assumptions of the atmosphere that cannot account for typical variations in wind velocity that occur in time and three-dimensional space. Here, a widely used mesoscale atmospheric model is used to improve forecasts of the location of the major axis of dispersion for erupting plumes. The Pennsylvania State University-National Center for Atmospheric Research fifth-generation Mesoscale Model (MM5) specializes in atmospheric prediction for regions on the order of ten to hundreds of kilometers on a side. …

Eros, Paideia And Arête: The Lesson Of Plato’S Symposium, Jason St. John Oliver Campbell

USF Tampa Graduate Theses and Dissertations

Commentators of Plato’s Symposium rarely recognize the importance of traditional Greek conceptions of Eros, paideia and arête in understanding Plato’s critique of the various educational models presented in the dialogue. I will show how Plato contests these models by proposing that education should consist of philosophy. On this interpretation, ancient Greek pedagogy culminates in a philosophical education. For this new form of education, the dialogical model supplants the traditional practices of kléos and poetic mimēsis, inextricably bound to archaia paideia and traditional forms of education. Plato’s Socrates is searching for knowledge and immortality through an application of the philosophical method, …

Relationship Of Waste Characteristics To The Formation Of Mineral Deposits In Leachate Collection Systems, Antonio J. Cardoso

USF Tampa Graduate Theses and Dissertations

Landfill leachate is generated as a result of reactions between water percolating through the landfill and wastes. Under normal conditions leachate is found at the bottom of landfills and from there, its movement can be controlled with collection systems to be treated, discharged, or recirculated. Landfill leachate collection systems are positioned above the liner and are designed to collect liquid under gravitational flow for the entire active, closure, and post-closure periods. Clogging of any portion of the system can lead to higher hydraulic heads and increase the potential for leakage through the liner.

To reduce the quantity of municipal solid …

Social Construction Of Cervical Cancer Screening Among Women In Panama City, Panama, Arlene Calvo

USF Tampa Graduate Theses and Dissertations

To learn how to address health issues specific to Hispanic cultures in an effort to address health disparities, learning from cultural aspects that affect health from the countries of origin would be most useful.

Qualitative research techniques offer powerful alternatives for public health professionals to develop adequate and directed programs at the community level, especially among underserved communities and those represented by oral/spoken traditions. The study was conducted among 132 working class single and married Mestizo women between the ages of 20-40 living in …

Trade And Plunder Networks In The Second Seminole War In Florida, 1835-1842, Toni Carrier

USF Tampa Graduate Theses and Dissertations

The Second Seminole War in Florida, 1835-1842, was a time of disruption and upheaval for all of those unfortunate enough to occupy the territory of Florida during the seven years of this protracted battle over Seminole removal to the West. Illicit trade was a major factor which enabled the Seminoles to resist removal for such an extended period. Illicit trade requires outside assistance. Documentary evidence suggests that such assistance was rendered by Spanish fishermen, English and American wreckers, slaves, free blacks, Native Americans and white American settlers. This thesis examines the evidence for plunder and illicit trade, and the possible …

The Effect Of Perceived Entitativity On Implicit Image Transfer In Multiple Sponsorships, Francoì?Is Anthony Carrillat

USF Tampa Graduate Theses and Dissertations

This dissertation proposes that in the case of multiple sponsorships (i.e., brands sponsoring concomitantly the same event), the group constituted by the sponsoring brands and the sponsored event will be perceived as an entity; a phenomenon that Campbell (1958) called entitativity. The extent to which a group of brands and a sponsored event is seen as being entitative will result in stereotypic processing of the group members (Brewer and Harasty 1996). Information about an entitative group is abstracted and used to form judgments about every group member (McConnell, Sherman, and Hamilton 1997). Characteristics tied to one brand or to the …

Effects Of Social Skills Training On The Interpersonal Behaviors Of Elementary School Students In An After-School Program, Robert Caples

USF Tampa Graduate Theses and Dissertations

Social skills training was investigated in an after-school program setting with four seven- and eight-year-old males. Two were Hispanic and two were African-American. Social skills training consisted of a direct instruction, behavioral learning model of skillstreaming as described by McGinnis & Goldstein (1997). There were four major components to each social skills training session: (1) an explanation of the skill being taught; (2) modeling by the researcher of the skill being taught; (3) role play by each of the participants; and (4) performance feedback regarding the role plays. Sessions lasted approximately 30 minutes and were held weekly throughout the intervention …

An Evaluation Of The Dopaminergic Systems’ Response To A Natural Reinforcer: A Comparison Between Cocaine Pretreatment In Adolescent And Adult Rats, Briony Catlow

USF Tampa Graduate Theses and Dissertations

The long-term consequences of adolescent drug use in shaping a network primed for addiction is an issue of utmost importance. The use of cocaine during adolescent development could alter the normal growth of the reward system and affect the adult mesolimbic system, however, there is scant literature aimed at finding out if animals are more vulnerable to the adverse effects of drugs during adolescence. The present study investigated whether cocaine pretreatment in adolescent and adult rats produced differences in cocaine-induced neurochemical cross-sensitization to a naturally reinforcing substance in adulthood. To evaluate the responsivity of the mesolimbic system after repeated cocaine, …

Fabrication Of Palladium Nanoparticles And Nanoporous Alumina Templates, Pavani Chennapragada

USF Tampa Graduate Theses and Dissertations

Nanostructured materials have potential technological applications due to their characteristic dimensions. The material performance will depend on the atomic structure, and composition of these materials. This thesis focuses on proposing a reliable method for fabricating nanoporous alumina and palladium nanoparticles inside the templates. Palladium nanoparticles were synthesized in commercial porous alumina templates using electrodeposition. Pores within these nanoporous membranes act as templates for the synthesis of nanostructures of the desired material. Electrodeposition is achieved using a three-terminal set-up and a potentiostat. Different types of deposition techniques were investigated to improve the distribution of the deposit. The nanoparticles were characterized by …

A Co-Orientational Analysis Of Public Involvement Perceptions In The Transportation Process: A Case Study, Kristen E. Carson

USF Tampa Graduate Theses and Dissertations

This study explored public involvement within the Florida Department of Transportation (FDOT) using the co-orientational theory. Effective public involvement gives the public opportunities to be involved early in the planning and implementation of transportation projects that directly affect or may concern them. The co-orientational model looks at what an organization (FDOT) thinks about an issue (public involvement), what the public thinks of the issue, what the organization thinks the public thinks about the issue, and what the public thinks the organization thinks about the issue.

This study investigated whether the FDOT management has an accurate understanding of the perceptions of …

Learning To Dance While Becoming A Dancer: Identity Construction As A Performing Art, Matthew A. Caudill

USF Tampa Graduate Theses and Dissertations

In a university undergraduate dance department, students seem to be learning more than pirouettes and pas de bourées; students are learning how to construct their identities and present themselves as ‘dancers’. As they progress through their undergraduate careers, the students are not only developing technical skills, but they are also learning the ins and outs of how dancers look, speak and behave. Based on three months of observation and in-depth interviews, it seems that developing into a dancer requires developing into an individual who shows unique commitment both to him/herself and to the art of dance itself. While many …

The Predictive Validity Of Four Reading Fluency Measures On A State's "High-Stakes" Outcome Assessment, Jose Michael Castillo

Sound Localization Abilities Of Two Florida Manatees, Trichechus Manatus Latirostris, Debborah E. Colbert

USF Tampa Graduate Theses and Dissertations

Florida manatees (Trichechus manatus latirostris) live in the shallow, often turbid inland and coastal waters of the southeastern United States. Since their vision is poor (Bauer et al., 2003), other senses probably guide orientation. Previous studies have found that manatees can hear over 40 kHz (Gerstein et al., 1999) and have the capacity for rapid auditory temporal processing (Mann et al., 2005). However, it is not known if manatees have the ability to localize underwater sounds.

Two Florida manatees were trained to identify underwater sound source locations using a four-choice discrimination paradigm. Three broad-band signals ( 0.2 - …

The Effects Of Response Cards On The Performance And Generalization Of Parenting Skills, Bennie L. Colbert

USF Tampa Graduate Theses and Dissertations

Previous research has provided convincing evidence of the efficacy of behavior analytic interventions to improve parenting skills with biological parents, however many studies lament generalization failure from training to home settings. Previous research has also examined the effects of response card use with children at various grade levels and with post-secondary students with a sole focus on academic outcomes. This study examined the effects of color coded response cards on active student responding and parenting skills proficiency of three foster parents in a parent training program and generalization of these skills to their homes.
