Building A Brighter Future Through Education: Student Housing For Single Parent Families, Carrie Cogsdale

USF Tampa Graduate Theses and Dissertations

On the possibilities of a child the Center for Disease Control says, “Every Child

should have the opportunity to reach their full potential”. (CDC) Children who grow up

in low-income families are at risk of falling behind in education before they even enter

kindergarten. Single parents that struggle to provide food and shelter often lack the time

and the resources to provide the early education that their children need. A college

education could provide these parents and their children with a better quality of life.

University student housing could include built in childcare services, educational

assistance and peer support, for …

Dressing Psychic Wounds: Clothing As Metaphor In Paule Marshall's Praisesong For The Widow And Leslie Marmon Silko's Ceremony, Angela D. Tartaglia

USF Tampa Graduate Theses and Dissertations

I investigate the function of dress as it relates to cultural retention in Paule Marshall's Praisesong for the Widow and Leslie Marmon Silko's Ceremony, drawing upon the work of fashion theorists Joanne Entwistle, Alison Lurie and Anne Hollander. My examination of the two novels is informed by several excellent scholarly works which hold that characters' well being is determined by the extent to which they connect with their folkloric roots, the central message in both Ceremony and Praisesong for the Widow. I build on this discourse by demonstrating that the novels' consistent attention to clothing is a device …

Gulliver’S Travels To The Screen, Giant And Tiny, Mark Dekle

USF Tampa Graduate Theses and Dissertations

Gulliver's Travels, by Jonathan Swift, has captured readers' imaginations for almost three hundred years, spawning countless adaptations over several different mediums. As different means of communicating and transforming art have been invented, these adaptations have grown to fill the new mediums and make use of the various possibilities each form has created. Film in particular has created an enormous opportunity to re-imagine Gulliver's Travels, since it can directly show the audience the fictional foreign locations in which Gulliver finds himself.

In this study, I examine seven screen adaptations of Swift's novel to determine what our current culture views as …

The Biomechanics Of Reverse Shoulder Arthroplasty, Sergio Gutiérrez

USF Tampa Graduate Theses and Dissertations

Rotator cuff deficiency with glenohumeral arthritis presents a unique challenge to the orthopaedic surgeon. Under these conditions, total shoulder replacement has yielded poor results as a result of eccentric loading of the glenoid leading to loosening and early failure. Multiple procedures have been recommended to resolve this problem including total shoulder arthroplasty, shoulder arthrodesis, and hemiarthroplasty. Hemiarthroplasty, the current standard of care for this condition, offers only limited goals for functional improvement and only a modest improvement in pain.

Recently, there has been renewed interest in reverse shoulder arthroplasty. The main concept behind the reverse shoulder implant is the stabilization …

Synergy And Resistance Mechanisms In R115777 And Ps-341 Models Of Myeloma And Leukemia, Robert William Buzzeo

USF Tampa Graduate Theses and Dissertations

The farnesyl transferase inhibitor R115777 (Zarnestra, Tipifarnib) has been found to have clinical activity in diverse hematopoietic tumors. Clinical efficacy, however, does not correlate with Ras mutation status or inhibition of farnesyl transferase. To further elucidate the mechanisms by which R115777 induces apoptosis and to investigate drug resistance, we have identified and characterized a R115777-resistant human myeloma cell line. 8226/R5 cells were found to be at least 50 times more resistant to R115777 compared with the parent cell line 8226/S. 8226/R5 cells were insensitive to a diverse group of antitumor agents including PS-341 (Bortezomib, Velcade). Comparison of gene expression profiles …

Southern Rock Music As A Cultural Form, Brandon P. Keith

USF Tampa Graduate Theses and Dissertations

Southern rock bands of the 1970s were a cultural formation that displayed racially and politically progressive views in the post-civil rights South through the cultural form of southern rock music. Southern rock bands, such as The Allman Brothers Band, and Lynyrd Skynyrd, responded to the political and social changes in the South brought forth by the civil rights movement by reconciling pride for southern heritage with progressive racial views through their music. The southern rock era was essentially between the years of 1969, when The Allman Brothers Band released their first album, until 1977, whe n a tragic airplane crash …

The Florida Education Finance Program From 1981 To 2009: A Historical Review And Equity Analysis, Curtis Todd Bowden

USF Tampa Graduate Theses and Dissertations

In 1973, the state of Florida implemented the Florida Education Finance Program (FEFP). The program was developed to distribute available funds to public school districts in a more equitable manner than the Minimum Foundation Plan it replaced. Almost immediately, the Florida Education Finance Program came under attack as less equitable and unnecessarily complex.

The Florida Education Finance Program provides funding to local school districts based on the number students and the types of educational programs in which they are enrolled. Through a system of program cost factors and district cost differentials the Florida Education Finance Program adjusts for the type …

Robots Without Faces: Non-Verbal Social Human-Robot Interaction, Cindy L. Bethel

USF Tampa Graduate Theses and Dissertations

Non-facial and non-verbal methods of affective expression are essential for naturalistic social interaction in robots that are designed to be functional and lack expressive faces (appearance-constrained)such as those used in search and rescue, law enforcement, and military applications. This research identifies five main methods of non-facial and non-verbal affective expression (body movement, posture, orientation, color, and sound). From the psychology, computer science, and robotics literature a set of prescriptive recommendations was distilled for the appropriate non-facial and non-verbal affective expression methods for each of three proximity zones of interest(intimate: contact - 0.46 m, personal: 0.46 - 1.22 m, and social: …

We tracked the evolution of the anisotropy peaks with varying magnetic field, temperature, and interaction strength. The anisotropy peaks of weakly interacting particles appears as non-symmetric peaks and at lower fields …

A Family „Affear‟: Three Generations Of Agoraphobics, Sherri Elizabeth Green B.A.

USF Tampa Graduate Theses and Dissertations

My thesis explores the disabling condition agoraphobia with panic disorder across the life spans of three individuals who are related: 63 year old Grandmother, her daughter - 43 year old Mother, and her grandson - 23 year old Son. As their life stories are told, glimpses of experienced stigma, emotional management, creation of identities, and coping mechanisms are revealed. These are analyzed using the sociological theories of Goffman, Ellis, Cahill, and Davidson. The notion of nature versus nurture is most apparent in Son's story which details the effects of growing up with Grandmother's severe agoraphobic episodes. While each individual does …

Identification And Characterization Of Mitochondrial Genome Concatemers In Aids-Associated Lymphomas And Lymphoma Cell Lines, Felipe Bedoya

USF Tampa Graduate Theses and Dissertations

Despite recent advances in the understanding of the molecular bases of hematological malignancies, the specific mechanisms on how they originate and why some subtypes are more prevalent than others still remain to be elucidated. These two important aspects have been even more difficult to analyze when dealing with individuals under immune suppression because other factors must be considered. Questions still remain as to why individuals with AIDS tend to develop lymphoproliferative disorders differently from those observed in individuals under iatrogenic immunosuppressive therapy. Most of lymphomas occurring in transplant recipients are B-cell neoplasias typically associated with Epstein-Barr virus (EBV) infection. In …

Evaluating The Effects Of Exergaming On Physical Activity Among Inactive Children In A Physical Education Classroom, Victoria A. Fogel

USF Tampa Graduate Theses and Dissertations

Childhood obesity is a serious concern that requires the attention of the behavioral community. The U.S. Department of Health and Human Services (2007) recommends that children engage in physical activity for 60 minutes per day. Children spend the majority of their day in school, making school an ideal environment to increase the opportunity for physical activity. Simple, straightforward interventions that can be applied in the school setting, which take into consideration the environment and focus on maintenance by making the process of engaging in physical activity reinforcing, are greatly needed. Video games have been noted in the literature as a …

Toward Understanding Low Surface Friction On Quasiperiodic Surfaces, Keith Mclaughlin

USF Tampa Graduate Theses and Dissertations

In a 2005 article in Science [45], Park et al. measured in vacuum the friction between a coated atomic-force-microscope tip and the clean two-fold surface of an AlNiCo quasicrystal. Because the two-fold surface is periodic in one direction and aperiodic (with a quasiperiodicity related to the Fibonacci sequence) in the perpendicular direction, frictional anisotropy is not unexpected; however, the magnitude of that anisotropy in the Park experiment, a factor of eight, is unprecedented. By eliminating chemistry as a variable, the experiment also demonstrated that the low friction of quasicrystals must be tied in some way to their quasiperiodicity. Through various …

A Greener Vertical Habitat: Creating A Naturally Cohesive Sense Of Community In A Vertical Multi-Family Housing Structure, Justin Onorati

USF Tampa Graduate Theses and Dissertations

Throughout multiple dense, tropical, urban contexts, high rise residential environments have created a sense of social detachment, where public and private green spaces do not often exist. It is through these varieties of green spaces that social interaction is encouraged, and without these social activities taking place, this vertical community becomes almost a meaningless entity within the urban realm. The issue being addressed within this thesis is the scarcity of public and private green spaces within our high density tropical urban fabrics that help to create a sense of community. The majority of dense urban settings that we inhabit today …

Probing Interactions And Phase Separations Of Proteins, Colloids And Polymers With Light Scattering, Avanish Singh Parmar

USF Tampa Graduate Theses and Dissertations

The broad objective of my research is to investigate the physical characteristics and interactions of macromolecules and nanoparticles, and the corresponding effects on their phase separation behavior using static and dynamic light scattering (SLS & DLS). Light scattering provides a non-invasive technique for monitoring the in-situ behavior of solutes in solution, including solute interactions, sizes, shapes, aggregation kinetics and even rheological properties of condensed phases. Initially, we investigated lysozyme solutions for the presence of preformed aggregates and clusters that can distort the kinetics of protein crystal nucleation studies in this important model system for protein crystallization. We found that both …

Green Local Governments In Florida: An Analysis Of Sustainability And Green Building Policies, Naimish S. Upadhyay

USF Tampa Graduate Theses and Dissertations

Sustainable development is increasingly being integrated within local government planning across United States. Many communities are attempting to translate this general principle into specific and measurable terms. The urban sustainability planning literature has mostly focused on descriptive case studies of pioneering cities that have been characterized as true innovators in their sustainability efforts. Noticeably absent from the literature, however, has been an examination of the sustainable development claims made by local governments undergoing 'green' certifications. This study evaluates the commitment and efforts of municipalities and counties of Florida within the framework of Florida Green Building Coalition's 'Green …

Rape Attitudes And Beliefs: A Replication Study, Rhissa Emily Briones

USF Tampa Graduate Theses and Dissertations

The phenomena of sexual violence have been studied on college campuses for over 50 years. Despite changes in society's attitudes towards women and gains made by women in education and the work force since the 1960s, research reveals that the incidence and prevalence rates of date rape have not changed significantly over the years. Extant literature indicates that endorsement of rape myths has been found to be associated with sexual aggression by males. A review of existing instruments revealed that current assessments of rape supportive attitudes and beliefs appear outdated in their language and may not be geared for today's …
