On the cusp of the organization, shareholder management is a central job of CEOs in the 21st century. This study focuses on CEO presentations to shareholders for American, Delta and Frontier Airlines before …


High School Outcomes Of Middle School Bullying And Victimization, Marissa A. Feldman Mar 2008

High School Outcomes Of Middle School Bullying And Victimization, Marissa A. Feldman

USF Tampa Graduate Theses and Dissertations

Previous research has revealed that bullying behaviors are negatively related to psychological, behavioral, social, and academic development. However, much of what is known has been determined from cross-sectional or year-long longitudinal studies conducted in elementary or middle school. The present study examined the longer-term correlates of bullying and victimization during the critical transition from middle to high school. Archival data from a large southern school district examined the longer-term implications of bullying and victimization of a middle school cohort (N=1,249). Results revealed that, during the initial survey year and over the following four-year period, self-identification as a bully was related …

The Paleoindian Chipola: A Site Distribution Analysis And Review Of Collector Contributions In The Apalachicola River Valley, Northwest Florida, William D. Tyler Mar 2008

The Paleoindian Chipola: A Site Distribution Analysis And Review Of Collector Contributions In The Apalachicola River Valley, Northwest Florida, William D. Tyler

USF Tampa Graduate Theses and Dissertations

At the end of the Pleistocene and the beginning of the Holocene, between 12,000 and 10,000 years ago, humans began to spread throughout North America and into many areas of Florida. These first Floridians are known as Paleoindians, and their culture is largely defined by their lithic assemblage, which includes the well known Clovis point. As the Pleistocene ice age came to a close glaciers melted, rivers experienced a drastic increase in water volume and the landmass of Florida began to shrink as the sea level in the Gulf of Mexico rose. This event likely submerged many early Paleoindian sites …


Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang Mar 2008

Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang

USF Tampa Graduate Theses and Dissertations

Work zone tends to cause hazardous conditions for drivers and construction workers since work zones generate conflicts between construction activities and the traffic, therefore aggravate the existing traffic conditions and result in severe traffic safety and operational problems. To address the influence of various factors on the crash severity is beneficial to understand the characteristics of work zone crashes. The understanding can be used to select proper countermeasures for reducing the crash severity at work zones and improving work zone safety. In this dissertation, crash severity models were developed to explore the factor impacts on crash severity for two work …

Development Of An Ecological Model To Predict Risk For Acquisition Of Clostridium Difficile-Associated Diarrhea During Acute Care Hospitalization, Susan Elaine Steele

USF Tampa Graduate Theses and Dissertations

Background: The traditional model of infection control has failed to stop the spread of emerging infectious diseases such as Clostridium difficile-associated diarrhea (CDAD) in the acute care environment. Ecological models, which rely upon identification of susceptible hosts, offer an alternative to the prevention of deadly outbreaks. Previous epidemiological research has identified a number of risk factors associated with CDAD. Utilization of this body of research by nurses is limited due to methodological issues that introduce bias and confounding, and use of variables that have limited meaning to the practicing clinical nurse.

Aim: The aim of this study was to …


An Electromechanical Synchronization Of Driving Simulator And Adaptive Driving Aide For Training Persons With Disabilities, Rufael Berhane Mar 2008

An Electromechanical Synchronization Of Driving Simulator And Adaptive Driving Aide For Training Persons With Disabilities, Rufael Berhane

USF Tampa Graduate Theses and Dissertations

Cars have become necessities of our daily life and are especially important to people with disability because they extend their range of activity and allow participation in a social life.

Sometimes driving a normal car is impossible for individuals with severe disability and they require additional driving aide. However, it is dangerous to send these individuals on the road without giving them special training on driving vehicles using an adaptive aide.

Nowadays there are a number of driving simulators that train disabled persons but none of them have joystick-enabled training that controls both steering, gas and break pedal. This necessitates …

Investigating The Role Of Appearance-Based Factors In Predicting Sunbathing And Tanning Salon Use, Guy Cafri

USF Tampa Graduate Theses and Dissertations

Understanding the motives for sunbathing and indoor tanning is an extremely important public health issue. UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors for the development of skin cancer. Psychosocial models of UV exposure are often based on theories of health behavior, but theory from the body image field can be useful in understanding motives to UV expose as well. The current study examines models that prospectively predict sunbathing and indoor tanning behaviors using constructs and interrelationships derived from the tripartite theory of body image (Thompson et al., 1999), as well …

Secondary Pre-Service Teachers’ Knowledge And Confidence In Dealing With Students’ First Amendment Rights In The Classroom, Ian Call Mar 2008

Secondary Pre-Service Teachers’ Knowledge And Confidence In Dealing With Students’ First Amendment Rights In The Classroom, Ian Call

USF Tampa Graduate Theses and Dissertations

Every year teachers find themselves involved in conflicts dealing with violations of students' First Amendment rights to freedom of expression and freedom of religion. Students and parents file lawsuits against school districts because they feel teachers and administrators have violated their First Amendment rights. As a result, many teacher preparation programs require pre-service teachers to learn about educational law and the rights students have at school. Yet, little research exists about how well pre-service teachers are prepared to deal with First Amendment issues in the classroom.

The purpose of this study was to investigate how well pre-service teachers are prepared …


The Study Of Compensatory Motions While Using A Transradial Prosthesis, Stephanie Lutton Carey Mar 2008

The Study Of Compensatory Motions While Using A Transradial Prosthesis, Stephanie Lutton Carey

USF Tampa Graduate Theses and Dissertations

Improvement of prostheses requires knowledge of how the body adapts. A transradial prosthesis without a dynamic wrist component may cause awkward compensatory motion leading to fatigue, injury or rejection of the prosthesis. This work analyzed the movements of shoulder, elbow and torso during four tasks: drinking from a cup, opening a door, lifting a box and turning a steering wheel.

The main purpose of this study was to determine if using a basic transradial prosthesis that lacks motion of the forearm and wrist would cause significant compensatory motion of the shoulder, elbow and torso during the tasks. The second purpose …


A Framework For Evaluating The Computational Aspects Of Mobile Phones, David Pedro Aguilar Mar 2008

A Framework For Evaluating The Computational Aspects Of Mobile Phones, David Pedro Aguilar

USF Tampa Graduate Theses and Dissertations

With sales reaching $4.4 billion dollars in the first half of 2006 in the United States alone, and an estimated 80% of the world receiving coverage for their wireless phones in that year, interest in these devices as more than mere communicators has greatly increased. In the mid-to-late 1990s, digital cameras began to be incorporated into cellphones, followed shortly thereafter by Global Positioning System (GPS) hardware allowing location-based services to be offered to customers. Since then the use of mobile phone hardware for non-communication purposes has continued to expand. Some models, such as the Motorola V3M, have been specifically geared …

Computer-Based Instruction And Remedial Mathematics: A Study Of Student Retention At A Florida Community College, Carol A. Zavarella

USF Tampa Graduate Theses and Dissertations

Computer-based instruction including distance learning is fast becoming an integral part of higher education. Much of the current research has found that computer-based instruction is as effective as lecture-based instruction. Despite the wealth of studies that purport that students enrolled in computer-based instruction perform equally well as compared to their lecture-based counterparts, there is a high dropout rate associated with computer-based instruction including distance learning.

The purpose of this study was to examine the differences in students' withdrawal and completion rates in classes delivered via different instructional formats (distance learning, hybrid, or traditional) to determine if student learning style and/or …

A Constant Struggle: Renegotiating Identity In The Aftermath Of Rape, Jo Aine Clarke Mar 2008

A Constant Struggle: Renegotiating Identity In The Aftermath Of Rape, Jo Aine Clarke

USF Tampa Graduate Theses and Dissertations

The academic study of rape has historically ignored the recovery experience of the person being raped. Beyond medical and physical effects, and the possibility of legal prosecution, little attention has been paid. Existing research loses sight of the survivor's experience, ignoring the fact that a rape affects every aspect of life. The trauma is not only physical, but also impinges on the emotional, intellectual and interpersonal spheres. Rape can be, and often is, a life-threatening experience: one that needs to be faced and dealt with before there can be any sort of productive future. While it has been demonstrated that …

Schools As Moderators Of Neighborhood Influences On Adolescent Academic Achievement And Risk Of Obesity: A Cross-Classified Multilevel Investigation, Bethany A. Bell-Ellison

USF Tampa Graduate Theses and Dissertations

Grounded in Bronfenbrenner's (1979) Ecological Systems Theory and through the application of cross-classified random effects models, the goal of this study was to examine simultaneously neighborhood and school influences on adolescent academic achievement and risk of obesity, as well as the moderating effects of schools on these outcomes. By examining concurrently neighborhood and school influences on achievement and risk of obesity, this study aimed to fill gaps in the social determinants literature. For example, it is unclear if where an adolescent lives or where she/he attends school has a stronger influence on academic achievement. We also do not know if …


A Modified Obesity Proneness Model In The Prediction Of Weight Status Among High School Students, Joyce E. Nickelson Mar 2008

A Modified Obesity Proneness Model In The Prediction Of Weight Status Among High School Students, Joyce E. Nickelson

USF Tampa Graduate Theses and Dissertations

The health and well-being of U.S. children is challenged by the immense crisis of obesity. The obesity proneness model, first described by Costanzo and Woody (1985), describes one mechanism by which parents influence obesity development. This model suggests that parents become concerned about their children's weight if their children show signs of becoming overweight and parents value weight highly. Parents communicate their concerns to their children and restrict their children's eating. Children internalize parents' concerns and become unable to regulate their eating. Hence, parents socialize children to be concerned about their weight but do not equip them to regulate eating, …


I Am Warrior Woman, Hear Me Roar: The Challenge And Reproduction Of Heteronormativity In Speculative Television Programs, Leisa Anne Clark Mar 2008

I Am Warrior Woman, Hear Me Roar: The Challenge And Reproduction Of Heteronormativity In Speculative Television Programs, Leisa Anne Clark

USF Tampa Graduate Theses and Dissertations

This paper explores how the "warrior woman" trope in western culture, as portrayed in late 20th century science fiction/fantasy and speculative television, reflects heteronormative/heterosexist discourses of femininity in American culture. First, I will examine feminine discourse in American culture, especially in the late 20th century. Then I will discuss how the tenets of second and third wave feminism influenced western paradigms of "the ideal female" and impacted pop culture by producing "warrior women" who both reflected and challenged heteronormative ideas and feminist principles. By examining several television shows produced in the United States and Great Britain from the late 1960s …
