Virtual Cadaver Navigation System: Using Virtual Reality For Learning Human Anatomy, Abhijit V. Lothe

USF Tampa Graduate Theses and Dissertations

The use of virtual reality (VR) for visualization can revolutionize medical training by simulating real world medical training procedures through intuitive and engaging user interface. Existing virtual reality based visualization systems for human anatomy are based on 3D surface and volumetric models and simulative systems based on model libraries. The visual impact as well as facilitation for learning are inadequate in such systems. This thesis research is aimed at eliminating such inadequacies by developing a non-immersive virtual reality system framework for storage, access and navigation of real human cadaveric data. Based on this framework, a real time software system called …

Effects Of Adoptive Transfer Of Beta-Amyloid Sensitive Immune Cells In A Mouse Model For Alzheimer’S Disease, Daniel Shippy

USF Tampa Graduate Theses and Dissertations

One major therapeutic target for preventing and treating Alzheimer's Disease (AD) is removal of excess β-amyloid (Aβ) from the brain. Both active and passive immunotherapies targeting Aβ have proven effective in reducing brain Aβ levels and improving cognitive function in mouse transgenic models of AD. However, these approaches can induce adverse neuropathologic effects and immunologic over-activation. Indeed, clinical trials of active Aβ immunotherapy in AD patients were halted due to development of meningoencephalitis, apparently resulting from wide-spread neuroinflammation. Here we show that a more restricted and specific immune re-activation through a single adoptive transfer of Aβ-specific T cells can provide …

Investigating Affective Dimensions Of Whiteness In The Cultural Studies Writing Classroom: Toward A Critical, Feminist, Anti-Racist Pedagogy, Allison Brimmer

USF Tampa Graduate Theses and Dissertations

This dissertation seeks to help teachers understand the ways that affect is tied to the dominant ideology of white supremacy in contemporary U.S. society. It argues that affect—the complex confluence of feeling and judgment—is bound intricately to racism, sexism, classism, heterosexism, etc. In this work I attempt to deconstruct the social construction of affect that fuels dominant white ideology— what some scholars call whiteness—in the context of white teachers and students in the cultural studies writing classroom. With the lofty yet ultimately empowering goal of effecting anti-racist change in the classroom and in the profession, I trace affective dimensions of …

Negotiating Curricular Boundaries And Sexual Orientation: The Lived Experiences Of Gay Secondary Teachers In West Central Florida, Jr., James B Mayo Jr.

USF Tampa Graduate Theses and Dissertations

There is little known about the daily lives of gay teachers at school. Studies have been conducted in this area, but the wide range of individual life experiences makes it difficult to define the gay teacher experience. Gay teachers geographic location, gender, age,and race, are a few of those factors that will have a direct influence upon their lives.Therefore, I believe more focused, regional or case studies will yield better understandings of the lives that gay teachers lead at school.

Until now, no other study had investigated the lives of gay teachers in West Central Florida. I decided to focus …

Measuring Transactional Distance In Online Courses: The Structure Component, Cheryl Sandoe

USF Tampa Graduate Theses and Dissertations

Online or web-based courses have become prolific in our educational environment over the past several years. The development of these courses can be guided by systematic design models to ensure quality instructional design. Transactional distance, the theory that claims the distance an online student feels is more of a pedagogical distance than a geographic one, consists of three factors: structure, dialogue, and learner autonomy. Accurate measurement of these three factors is needed in order to substantiate its claims and to best determine the delivery implications. This study produced an instrument that measures the structure component of the transactional distance theory …

Iontophoretic Trans-Dermal Drug Delivery Through Sweat Glands, Vardan Ter-Antonyan

USF Tampa Graduate Theses and Dissertations

Although an iontophoretic trans-dermal drug delivery is known as an effective means for drug transportation through the human skin, it is not widely used because of the various side effects that come to life due to a high applied voltage of up to 80V. This study introduces an alternative means of drug transportation through the skin by means of sweat gland activation and reduction of an applied voltage to ensure that the iontophoresis is safe. The skin conductance studies performed on the pulmar area using 50mM of NaCl showed that the activation of sweat glands led to the increase of …

School Experiences Then And Now: Are Parents' Perceptions Of Their Own School Experiences Related To Their Perceptions Of Their Child's Middle School?, Roxana M. Sanchez-Horn

USF Tampa Graduate Theses and Dissertations

The current study explored the relationship between parents perceptions of their childs middle school and parents perceptions of their own school experiences. Additionally, it was important to research how these relationships differed among variables. The variables explored were (1) race, (2) parents own educational backgrounds (level of education), and (3) socio-economic status. Based on scales commonly used in the study of parent involvement, a survey (i.e., Parent Perceptions of Schooling) was developed. The survey consisted of two parts (i.e., Part I, How I Feel About My Childs School and Part II: Parents Own School Experiences Questionnaire) and a demographic section …

The Voices Of Sex Workers (Prostitutes?) And The Dilemma Of Feminist Discourse, Justine L. Kessler

USF Tampa Graduate Theses and Dissertations

The existence of prostitution has been a longtime concern for many societies. It has also been a complicated issue within feminist discourse. Some women choose sex work as a viable economic option while others are forced into prostitution by traffickers and pimps and some are forced into it due to disadvantaged circumstances. The presence of sex work and prostitution is one of the occurrences that accompany a patriarchal capitalist system. Many feminists indeed argue that prostitution is a byproduct of a patriarchal capitalist system. The migration of women for sex work and the trafficking of women into prostitution cannot occur …

Gender And Generational Differences In The Self-Ratings Of Leadership Practices By Elementary School Administrators Within Four Florida Counties, Michele E. Polk

USF Tampa Graduate Theses and Dissertations

Considerable research has been conducted over time on possible gender differences, with varying results regarding the existence and/or degree of differences. In particular, research on differences in leadership practices of men and women have abounded since the 1970s as women began to make their way into management and supervisory positions.

In todays work force, several generations can be found working together within a single work setting. Possibly, differences in leadership may be more generational than gender related; however, little research has considered both gender and generation as variables. This study adds to literature relating to the existence of gender and/or …

Effect Of Age On 11- To 18-Year-Olds’ Discrimination Of Nuances In Instrumental And Speech Phrase Interpretations, Andrew Sioberg

USF Tampa Graduate Theses and Dissertations

This dissertation was a continuation of study on a theory of a learning window for the perception of expressive qualities in music and speech. The proposed theory suggested that a practice window must overlap a learning window before it closes around the age of 10. This dissertation sought to determine whether children older than the proposed learning window continued to improve in speech and musical discrimination skill, or leveled off in this ability. It also examined the impact of gender and private lesson experience on discrimination ability.

Instrumental music students (n = 292) attending a public magnet school for visual …

General Education Teachers And Classroom-Based Interventions: Knowledge, Training, And Building-Level Influences, Jenine M. Sansosti

USF Tampa Graduate Theses and Dissertations

Intervention assistance (IA) programs have been developed as a mechanism for avoiding costly special education referrals and for supporting teachers in their instruction of students with varying needs within the general education classroom (Safran and Safran, 1996). Although IA programs are designed to be consultative, multidisciplinary approaches to assisting teachers, some studies report that teachers conduct the majority of classroom-based interventions for a given student on their own prior to referring students to an IA team (Wilson, Hagen, Gutkin, and Oats, 1998). It is important to determine what interventions or strategies teachers commonly consider and what factors are associated with …

Experience And Inquiry In John Dewey’S Contextualism, Christopher C. Kirby

USF Tampa Graduate Theses and Dissertations

This paper will focus on two elements, viz. experience and inquiry, which are central to John Deweys philosophy and their relation to the movement known as pragmatism. Although each of these concepts has received extensive treatment by other schools of thought, the pragmatists, and particularly Dewey, did much to redefine each in hopes of alleviating the tension between conflicting philosophical viewpoints. An explication of Deweys view on experience is the first step in understanding his application of the pragmatic method towards reconstructing philosophical thinking. Therefore, this paper will explore the meaning that Dewey gave to each and how that meaning …

More Than Man’S Best Friend: A Look At Attachment Between Humans And Their Canine Companions, Samantha E. Kennedy

USF Tampa Graduate Theses and Dissertations

According to the American Veterinary Medical Association, there are currently more than 60 million pet dogs in the United States. This is an increase of nearly eighteen percent since 1991, coinciding with a growing area of research on human’s relationships with companion animals and companion animals’ place in society.

For years dogs have been thought of as “man’s best friend” because of their loyalty and faithfulness. The increasing popularity of activities such as canine daycare and puppy school suggests that dogs have become more than a best friend to some and even an integral part of the American family unit. …

Cognitive Load Theory And Programmed Instruction, Michael L. Brazas

USF Tampa Graduate Theses and Dissertations

Programmed Instruction was a dominant force in educational research during the 1960’s and early 1970’s. During this period a new cognitively oriented psychology of education arose that eventually replaced the behaviorally driven research into programmed instruction. For some reason little work was done on integrating these two approaches. This study was designed to test a programmed instructional system based on the intrinsic programmed instructional technology of Crowder (1961) but incorporating design elements derived from cognitive load theory (Sweller, 1988). Specifically, this study tested a multimedia programmed instructional system (CLT-PI) based on work by Mayer (2001) against a text based system …

Creative Performance On The Job: Does Openness To Experience Matter?, Victoria L. Pace

USF Tampa Graduate Theses and Dissertations

Finding what is alike among the personalities of creative people has been a dream of many researchers. No single personality type has been discovered as prototypical, yet the promise of common attributes among creative people remains enticing. This study examines one of these promising characteristics - Openness to Experience, a personality factor from the Five-Factor Model. This factor has been shown to correlate positively with creativity in past studies. In the present study this relationship was partially confirmed in a sample of employees whose jobs require technical problem solving, by correlating the employees self-rated Work-specific Openness to Experience and NEO …

The Effects Of Interracial Interaction On Behavior As A Function Of Prejudice And Race, Jason R. Read

USF Tampa Graduate Theses and Dissertations

In a series of two experiments, the first involving 121 participants and the second 114, I investigated whether level of racial prejudice is related to performance on a cognitive task and helping behavior in participants who had just interacted with the target of their prejudice. The moderating effect of control was tested and, unlike previous research, the responses of African-American participants were studied too. It was proposed that when people interact with the target of their prejudice, they will experience stress and the aftereffects of stress will lead to a decrement in Stroop task performance and a lower likelihood of …

The Effects Of A School-Based Social Skills Training Program On Children With Adhd: Generalization To The School Setting, Tricia C. Rudolph

USF Tampa Graduate Theses and Dissertations

A diagnosis of Attention-Deficit/Hyperactivity Disorder is given when a child exhibits developmentally inappropriate levels of inattention, impulsivity and hyperactivity. In addition to academic and behavior problems, these children often have significant social problems. Since social problems are associated with a greater risk for developing problems later in life, a number of interventions have been attempted to normalize the social interactions of children with ADHD. These have included stimulant medication, cognitive-behavioral interventions, behavior modification, and social skills training. Additionally, attempts have been made to maximize the benefits of these interventions by combining them. Typically this involves combining stimulant medication with one …

Neurochemical Analysis Of Cocaine In Adolescence And Adulthood, Kirstie Helen Stansfield

USF Tampa Graduate Theses and Dissertations

Adolescence is a time of high risk behavior and increased exploration. This developmental period is marked by a greater probability to initiate drug use and is associated with an increased risk to develop addiction and dependency in adulthood. Human adolescents are predisposed toward an increased likelihood of risk taking behaviors (Zuckerman M, 1986), including drug use or initiation. The purpose of this study was to examine differences in developmental risk taking behaviors and neurochemical responsivity to cocaine based on these behavioral characteristics. Adolescent and adult animals were exposed to a novel stimulus in a familiar environment to assess impulsivity, novelty …

County Level Predictors Of Homicide And Suicide In The State Of Florida, Kelly K. Browning

USF Tampa Graduate Theses and Dissertations

The present study expands the range of theoretical perspectives and empirical questions that have occupied the recent literature on homicide and suicide. The study examines county-level predictors for homicide and suicide in all sixty-seven counties in Florida. The current examination identifies which county-level variables are most closely related to each other, which variables explain the greatest amount of differences within the Florida counties, as well as which variables are most significantly correlated with the homicide and sucide rate by county. Additionally, the variables included in the present research are driven by the theorectical perspectives of social disorganization and anomie/strain theory. …

The Effects Of Hand Fidgets On The On-Task Behaviors Of A Middle School Student With Disabilities In An Inclusive Academic Setting, Karen S. Voytecki

USF Tampa Graduate Theses and Dissertations

Many students with mild disabilities display off-task behaviors during academic content classes. The off-task behaviors can negatively impact their academic progress. In primarily clinical settings, specific interventions derived from the theory of sensory integration have been shown to increase on-task behaviors in students with mild disabilities. Using a single subject A-B-A-B withdrawal design, the researcher investigated the effects of hand fidgets on on-task behaviors demonstrated by a middle school student with mild disabilities who typically displayed off-task behaviors when participating in an inclusive, academic content class (language arts). Social validity was assessed to evaluate student and teacher perceptions regarding the …

The Effects Of A Parent Intervention On The Phonological Awareness Skills Of Kindergarten Students, Andrea Ofiara

USF Tampa Graduate Theses and Dissertations

This study examined the efficacy of the Sound Foundations program, implemented by parents, for increasing phonological awareness (PA). Three kindergarten students identified with PA deficits and their mothers served as participants. Parents implemented Sound Foundations twice per week for five and a half weeks. The effects of the intervention were evaluated using a multiple baseline across participants design. PA was measured using the Phoneme Segmentation Fluency measure of the Dynamic Indicators of Basic Early Literacy Skills. Results showed that two students showed increases over time in phonemes per minute after the parent intervention. A third student did not show substantial …

The Effects Of The Presence Of A Dog On The Social Interactions Of Children With Developmental Disabilities, Stephanie Walters

USF Tampa Graduate Theses and Dissertations

The effects of the presence of a dog on the social interactions between children with developmental disabilities and their teacher were analyzed in this study. We examined whether the presentation of a dog would improve the social interactions of three children with developmental disabilities. A baseline condition consisting of the child and teacher in the presence of three toys, one of which was a toy dog was followed by an intervention in which a real dog was added to the sessions. A multiple baseline design across participants was employed to assess experimental changes in interactions during the intervention condition.

Giving Voice To Parents Of Young Children With Challenging Behavior, Jonathan Worcester

USF Tampa Graduate Theses and Dissertations

In recent years, there has been increased interest in the science of child development, particularly relative to early childhood (i.e., birth to 5 years) and children with challenging behavior. A broad interest in brain-behavior relationships and prevention services for young children has led to a renewed interest in the developmental significance of early life experiences (National Research Council and Institute of Medicine, 2000). Armed with an increasingly large body of neuroscience research, researchers have begun to examine the efficacy of prevention services and supports for young children and families, particularly those with challenging behavior (i.e., behaviors that interfere with optimal …

Toward A Social-Cognitive Psychology Of Speech Technology: Affective Responses To Speech-Based E-Service, Melanie Diane Polkosky

USF Tampa Graduate Theses and Dissertations

Speech technologies, or technologies that recognize and respond to human speech, have recently emerged as a ubiquitous and cost-effective form of customer self-service (e-service). Although customer satisfaction is regarded as an important outcome of e-service interactions, little is known about users affective responses to conversational interactions with technology. Using a theoretical foundation derived from research in social cognition, interpersonal communication, psycholinguistics, human factors, and services marketing, two studies develop items for a speech interface usability scale, which is then used to examine interrelationships among individual differences (e.g., self-monitoring, need for interaction with a service provider, inherent novelty seeking), usability, comfort, …

Reconstructing Women's Identities: The Phenomenon Of Cosmetic Surgery In The United States, Cara L. Okopny

USF Tampa Graduate Theses and Dissertations

The popularity of cosmetic surgery in the U.S. has increased dramatically over the last ten years - particularly for women, who make up the largest group of cosmetic surgery consumers. Cosmetic surgery can include relatively simple procedures such as permanent hair removal or Botox to more complicated procedures like breast augmentations and face-lifts. The rise in popularity of cosmetic surgery exalts only one kind of beauty and excludes many women from ever attaining this ideal, so while women may feel empowered, surgery acts as a form of assimilation, because the act of cosmetic surgery reifies an exclusionary beauty norm. With …
