Topology, Morphisms, And Randomness In The Space Of Formal Languages, David E. Kephart

USF Tampa Graduate Theses and Dissertations

This paper outlines and implements a systematic approach to the establishment, investigation, and testing of distances and topologies on language spaces. The collection of all languages over a given number of symbols forms a semiring, appropriately termed a language space. Families of languages are defined by interrelations among words. The traditional classification begins with the syntax rules or grammar of the language, that is, the word-transformations by which the entire language can be produced from a single axiom, or starting word. The study of distances between languages as objects and of the topologies induced by language distances upon spaces of …

The Rapid Unexpected, Daniel Pantano

USF Tampa Graduate Theses and Dissertations

These lyric poems were written between August 2003 and June 2005 and bear witness to the human condition in all its facets, from birth and the first taste of lemon ice to exile and suicide. Within a landscape that encompasses many locales, the poems included here attempt to portray the particular to denote the universal and are always confronted by the ineffable connection between the two.

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 …

Performance Optimization In Three-Dimensional Programmable Logic Arrays (Plas), Supriya Sunki

USF Tampa Graduate Theses and Dissertations

Increased chip size and reduced feature size has helped following Moores law for long decades. This has an impact on interconnect length, which is resulting in chip performance degradation. Despite the introduction of new materials with Low-K dielectrics for interconnects, their delay is expected to substantially limit the chip performance. To overcome this problem the need for new technology has arrived. One such promising technology is the three-dimensional Integrated chips (3D ICs) with multiple silicon layers.

In this thesis, three dimensional integrated chip (3D IC) technology has been implemented on programmable logic arrays (PLAs). The two-dimensional PLAs are converted to …

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 …

It is well known that acoustic forces generated by a flexural plate wave (FPW) device can cause fluid motion, by the principle of acoustic streaming. Also the proven ability of FPW devices to cause …

Role Of Stat3 In Regulating Hif-1alpha Expression And Tumor Angiogenesis, Jon J. Briggs

USF Tampa Graduate Theses and Dissertations

Increased vascularization (angiogenesis) is a required adaptation for sustained tumor growth, and the primary mediator of de novo blood vessel formation is vascular endothelial growth factor (VEGF). The central transcriptional activator of VEGF is hypoxia inducible factor-1 (HIF-1), a heterodimeric transcription factor composed of an inducible HIF-1α subunit and a constitutively expressed HIF-1β subunit. In addition to HIF-1, it has recently been reported that signal transducer and activator of transcription 3 (Stat3) is required for VEGF production and angiogenesis. Although it is known that Stat3 is an important mediator of many of the oncogenic signaling pathways that regulate HIF-1α, it …

Multi-Agent Workload Control And Flexible Job Shop Scheduling, Zuobao Wu

USF Tampa Graduate Theses and Dissertations

In the make-to-order (MTO) industry, offering competitive due dates and on-time delivery for customer orders is important to the survival of MTO companies. Workload control is a production planning and control approach designed to meet the need of the MTO companies. In this dissertation, a multi-agent workload control methodology that simultaneously deals with due date setting, job release and scheduling is proposed to discourage job early or tardy completions. The earliness and tardiness objectives are consistent with the just-in-time production philosophy which has attracted significant attention in both industry and academic community.

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 …

Dissertations: Past, Present, And Future, Matthew D. Barton

USF Tampa Graduate Theses and Dissertations

Current policies and traditions regulating the dissertation process are responsible for a devaluation of dissertations and fail to recognize the economic and technological developments wrought by the emerging Internet. Some of the problems with the current process involve ideology, such as the insistence that dissertations be single-authored, original, and owned by someone. Others involve adherence to traditions that no longer serve a useful purpose, such as forcing authors to conform to a format better suited to a printed book than an online project. Finally, economical considerations such as the costs involved with purchasing and training authors to use advanced technology …

Robust Algorithms For Property Recovery In Motion Modeling, Medical Imaging And Biometrics, Yong Zhang

USF Tampa Graduate Theses and Dissertations

The past two decades has witnessed growing interest in physics based techniques in computer vision, computer graphics and medical imaging. The main advantage of a physical model is its mathematical rigor and physical soundness, which makes it an ideal tool to study complex nonrigid motion. However, since a model based on continuum mechanics is computationally demanding, an idealized framework is often adopted where physical motion parameters are significantly simplified, which inevitably affects the accuracy and reliability of modeling results.

In this study, a new modeling approach is developed that features the reconstruction of actual material properties such as the Young's …

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 …

Exhaled Breath Nitric Oxide: Is There A Baseline Difference Due To Ethnicity?, Sunita I. Patel M.D.

In Poland World War I Ended In 1923, Kazimierz Robak

USF Tampa Graduate Theses and Dissertations

Poland was erased from European political maps in 1795 and fought in vain for freedom for the next century, until World War I provided another chance for independence. On November 11, 1918, the creation of the Polish Republic was proclaimed, but in an atmosphere of uncertainty, particularly relative to frontiers.

The border with Germany was established in 1920-21 after plebiscites. While peaceful in Masuria, Ermland and Pomerania, there were three violent uprisings of the ethnic Poles in Upper Silesia. The status of Gdansk as a Free City was confirmed at Versailles in 1919. The Southern border with Czechoslovakia was settled …

Assessment Of Invasive Activities Of Ovarian Cancer Cells In Vitro, Hetal Shah

USF Tampa Graduate Theses and Dissertations

The interactions between neighboring cells and between cells and their attached substrate have long been studied in tissue culture. These in vitro studies may provide information regarding cell behavior in vivo including cell movement, cell proliferation, tissue development and wound healing. Transcellular resistance (or impedance) measurements, using various dc or ac techniques have been used to study the barrier function of epithelial and endothelial cell layers. With an appropriate equivalent circuit used for data analysis, junctional resistance between cells and other cellular properties, including cell membrane capacitance, can be determined. However, these techniques have seldom been applied to fibroblastic cell …

Establishing A Farmers Market For A Low-Income Latino Community, Ann L. Bretnall

USF Tampa Graduate Theses and Dissertations

For the past decade, Florida’s Latino population has significantly increased and is now the third largest in the United States. The same trend has also occurred in Hillsborough County. Social and economic disparities are significant as Latinos earn less than non-Hispanic whites and many live in poverty. A major concern of this population is the lack of access to inexpensive fresh fruits and vegetables. Findings from prior research show that the diet of immigrants often change quickly upon their arrival to the United States, with an increased emphasis on fast food and soft drinks and a reduction in the consumption …

Metallic To Insulating Transition In Disordered Pulsed Laser Deposited Silicide Thin Films, Houssam Abou Mourad

USF Tampa Graduate Theses and Dissertations

A metal-to-insulating transition has been observed in iron, iron oxide, iron silicide and cobalt silicide thin films when deposited on Si substrate with a native SiOx layer. This transition produced a change in resistance of 5 orders of magnitude at a temperature of 250 K. To the best of the author's knowledge, this effect has not been reported in the literature prior to this study. This work reports a systematic experimental investigation carried out to understand the fundamental mechanism involved in the manifestation of this metal-to-insulator transition. The films were deposited using the pulsed laser deposition technique (PLD) in a …

Postmodern Narrativity In Absalom, Absalom! And Memento: Examining Telling Similarities In The Techniques Of William Faulkner And Christopher Nolan, Jessica Jain Williams

USF Tampa Graduate Theses and Dissertations

This paper argues that narrative techniques in Absalom, Absalom! demonstrate Faulkners anticipation of postmodern thought and style. Similar techniques in Christopher Nolans film Memento serve to highlight how both writer and director confound the notion of master narrative by disrupting chronology and raising questions about the reliability of the narrators in each work. Nolan orders all events of the film in reverse while threading chronologically ordered events throughout to tell the story of Lennys murder investigation. Faulkner likewise uses "dischronology," such as flashbacks to tell the story of Thomas Sutpen. Both Faulkner and Nolan provide key information through questionable narrators …

Ocean-Atmosphere Interactions On The West Florida Shelf, Jyotika I. Virmani

USF Tampa Graduate Theses and Dissertations

Ocean-atmosphere fluxes on the West Florida Shelf (WFS) coastal ocean region are investigated using observations and derived surface fluxes from an array of buoys deployed between 1998 and 2003. The observed annual cycle shows that water column temperatures increase and are stratified when heat flux is positive, and they decrease and are well mixed when it is negative. Water temperature is minimum (maximum) when heat flux switches sign from negative (positive) to positive (negative) in early spring (autumn). Tropical and extra-tropical events help define the seasonal characteristics of the water temperature. Despite considerable daily and synoptic variability in relative humidity, …

Incorporating Surficial Aquifer Ground-Water Fluxes Into Surface-Water Resource Management Studies, John Mccary

USF Tampa Graduate Theses and Dissertations

For surface-water resource management studies, it is important to quantify all of the mechanisms that contribute to water quantity and influence water quality. In this regard, various methods have been used to ground-water fluxes in lake systems. These have included physical measurements (e.g., seepage meters), flow-net analyses, water budgets, chemical tracers, ground-water flow models, and statistical analyses. The method developed for this study for calculating ground-water inflow uses a simplified, 1-layer (surficial aquifer) ground-water flow model. The test area was on a set of lakes known as the Winter Haven Chain of Lakes in Polk County, Florida. The technique combines …

Professional Wrestling, Embodied Morality, And Altered States Of Consciousness, Lawrence B. Mcbride

USF Tampa Graduate Theses and Dissertations

Much of the scholarly work on professional wrestling is based on the assumption that beyond a simple mimicking of sporting combat, the wrestling show is a spectacle that constructs and interrelates socially situated, morally significant categories. In this thesis, I focus on wrestlers themselves, and treat wrestling as a traditional practice that guides how wrestlers relate to their bodies and how they interact with their audience. This project was carried out using ethnographic methods of observation and interviewing. While participant-observation of three independent wrestling promotions provided context, twelve semi-structured interviews carried out with wrestlers at the Florida Wrestleplex in St. …

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 …
