Transducer Dynamics, Egor Dolzhenko

USF Tampa Graduate Theses and Dissertations

Transducers are finite state automata with an output. In this thesis, we attempt to classify sequences that can be constructed by iteratively applying a transducer to a given word. We begin exploring this problem by considering sequences of words that can be produced by iterative application of a transducer to a given input word, i.e., identifying sequences of words of the form w, t(w), t²(w), . . . We call such sequences transducer recognizable. Also we introduce the notion of "recognition of a sequence in context", which captures the possibility of concatenating prefix and suffix words to each word in …

Suzan-Lori Parks’S The America Play And Its Deconstructive Ontology, Rachel A. Naor

USF Tampa Graduate Theses and Dissertations

I intend to showcase Suzan-Lori Parks's repetitious, supplemental virtuosity, which is a testament to the fluid, indeterminate condition of her concepts. I seek to demonstrate that in textualizing the quality of absence in the written dialogue, Parks's The America Play becomes uniquely deconstructive. For indeed, through the absent "presence" of an historically mythified president and a gravedigger's skewed identity, the play becomes a stage for splinters of historicized, differentiating, repeating signifiers that supplement, even as they redefine, their referential signified. Performing deconstructive thinking, Parks's textuality is accommodated by a content through which she calls attention to the structures of metaphysics …

A Novel Biostable 3d Porous Collagen Scaffold For Implantable Biosensor, Young Min Ju

USF Tampa Graduate Theses and Dissertations

Diabetes is a chronic metabolic disorder whereby the body loses its ability to maintain normal glucose levels. Despite of development of implantable glucose sensors in long periods, none of the biosensors are capable of continuously monitoring glucose levels during long-term implantation reliably. Progressive loss of sensor function occurs due in part to biofouling and to the consequences of a foreign body response such as inflammation, fibrosis, and loss of vasculature.

In order to improve the function and lifetime of implantable glucose sensors, a new 3D porous and bio-stable collagen scaffold has been developed to improve the biocompatibility of implantable glucose …

Synthesis Of Novel Cysteine Peptide Nucleic Acid (Cpna), Mehul J. Ajmera

USF Tampa Graduate Theses and Dissertations

Many diseases are caused due to abnormalities in production of specific protein. Across this protein the conventional lock and key mechanism shows binding at the specific cites of protein. However use of antisense technology can prevent formation of protein. It does so by binding to mRNA and prevents transcription. The structural modifications lead to synthetic molecules with 18-mer units which show significant improvement in binding properties, this gives birth to a new class of oligomers called Peptide Nucleic Acid (PNA). We herein report cysteine based PNA called CPNA.

The Effects Of A Structured Adherence Intervention To Haart On Adherence And Treatment Response Outcomes, Donald E. Kurtyka

USF Tampa Graduate Theses and Dissertations

Background: Adherence to antiretroviral (ARV) medications in excess of 90-95% is necessary for optimal response to suppress HIV replication and to maintain and/or restore immune function. A number of interventions have been shown to improve ARV adherence, but no research has been conducted which evaluates proactive monitoring of pharmacy refill adherence and subsequent intervention when inadequate adherence is identified.

Purpose: The purpose of this project was to compare treatment response, pharmacy refill adherence and self-reported medication adherence between two groups of patients: those participating in an AIDS Drug Assistance Program (ADAP) and those participating in a Medicaid-funded medication access program. …

Privacy In Database Designs: A Role Based Approach, Gary A. Poe

USF Tampa Graduate Theses and Dissertations

Privacy concerns have always been present in every society. The introduction of information technology information has enabled a reduction in the cost of gathering information, management of that information and the permitted that same information to become increasingly portable. Coupled with these reductions of cost has been an increase in the demand for information as well as the concern that privacy expectations be respected and enforced through security systems that safeguard access to private-type data. Security systems enforce privacy expectations. Unfortunately there is no consensus on a definition of privacy making the specification of security often over broad and resulting …

Subconstituent Algebras Of Latin Squares, Ibtisam Daqqa

USF Tampa Graduate Theses and Dissertations

Let n be a positive integer. A Latin square of order n is an n×n array L such that each element of some n-set occurs in each row and in each column of L exactly once. It is well-known that one may construct a 4-class association scheme on the positions of a Latin square, where the relations are the identity, being in the same row, being in the same column, having the same entry, and everything else. We describe the subconstituent (Terwilliger) algebras of such an association scheme. One also may construct several strongly regular graphs on the positions …

Parent-Child Interaction Therapy For Children Diagnosed With Reactive Attachment Disorder, Demetria Soulounias-Arriaga

USF Tampa Graduate Theses and Dissertations

Parent-Child Interaction Therapy is a probably efficacious, evidenced-based

treatment, which has been proven to decrease problem behaviors of children, as well as

improve parent-child interactions. The first phase is the Child-Directed Interaction (CDI),

which allows the child to lead the play session, while parents are taught to interact

without giving demands, asking questions, or providing criticism. According to the

DSM-IV-TR, Reactive Attachment Disorder is a rare diagnosis. Many attachment

therapists indicate that traditional approaches to treatment have not been demonstrated as

being effective with these children. This study will examine the CDI phase of Parent-

Child Interaction Therapy as a …

How Similar Are Personality Scales Of The “Same” Construct? A Meta-Analytic Investigation, Victoria L. Pace

USF Tampa Graduate Theses and Dissertations

In recent years, meta-analytic reviews have estimated validities for the use of personality scales in the prediction of job performance from an array of empirical studies. A variety of personality measures were used in the original studies, and procedures and decisions concerning the categorization of these measures into Big Five personality factors have differed among reviewers. An underlying assumption of meta-analysis is that the predictors across included studies are essentially the same, as is the criterion. If this is not the case, then problems arise for both theoretical reasons and practical applications. If predictors that are not highly correlated are …

"Either You Conquer It, Or It Conquers You": An Applied Anthropological Approach To Veterans With A Spinal Cord Injury, Sherman Chow

USF Tampa Graduate Theses and Dissertations

Veterans with a spinal cord injury (SCI) engage in a complex and, often times, difficult dialogue within and through interactions in American society. That is, American society holds dear certain traditional values (ideals, beliefs, and customs) that promote the steady functioning and fabric of society. Through the process of enculturation and acculturation, likely, the majority of American citizens have already internalized many of these values. These values are cultural constructs of American society that can certainly influence and shape the myriad ways in which individual identity is formed.

By identifying these value sets and analyzing the ways in which SCI …

Reforming Dance Pedagogy: A Feminist Perspective On The Art Of Performance And Dance Education, Jennifer Clement

USF Tampa Graduate Theses and Dissertations

Dancers, in their formal training, are deprived of many basic human experiences and are often not exposed to critical thinking. Expectations about what it means to dance and/or be a dancer shape the classroom environment, performances and both the body and mind of individuals engaged in this particular art form. A professional dancer is expected to plan her day around the dance classroom and this mentality is shared by aspiring professionals as well as dance educators. This structure, in tandem with the expectations for a female dancer to maintain a certain body type- almost always a thin flexible body, toned …

Participatory Fandom In American Culture: A Qualitative Case Study Of Dragoncon Attendees, Katherine L. Fleming

USF Tampa Graduate Theses and Dissertations

With the rise of the mass media over the last century, fame and celebrity seem to have evolved into ever-growing phenomena. Likewise, audience members have sought increasing involvement with people or activities related to the focus of their interest. These individuals are not content to simply watch their favorite actors or films from home. Instead, they take a more active approach, engaging in activities related to their fandom as well as seeking interaction with each other in organized groups (in person and on the Internet), attending conventions, and seeking interaction with celebrities.

This study presents a discussion of fame, celebrity, …

Trace Metals And Stable Isotopes As Tracers Of Life History And Trophic Connections In Estuarine-Dependent Fish From Tampa Bay, Florida, Linae Marie Boehme-Terrana

USF Tampa Graduate Theses and Dissertations

Florida's estuaries support a wide range of species yet little is known about tracemetal cycling among members of this important ecosystem. To examine the flow of trace metals through the Tampa Bay estuary, four fish species representing different trophic levels were analyzed for copper (Cu), zinc (Zn) and stable isotopes of carbon (C) and nitrogen (N). Species selected were the striped mullet (Mugil cephalus), tidewater mojarra (Eucinostomus harengulus), bay anchovy (Anchoa mitchilli), and sand seatrout (Cynoscion arenarius). Juvenile fish were collected from the Alafia, Hillsborough, Palm, and Little Manatee Rivers. Adults were …

Land Use Policy And Practices In Karst Terrains, Spencer Fleury

USF Tampa Graduate Theses and Dissertations

Karst topography is the result of a specific combination of geological conditions, precipitation, biota, and temperature, and is characterized by the gradual solution of the underlying bedrock and the development of underground drainage routes for surficial runoff. Many of these karst landscapes are found in urbanized areas, where the potential for anthropogenic impact is quite high. In many instances, municipalities on karst terrains choose to mitigate these impacts by implementing ordinances that place restrictions on permissible land uses near karst landforms. This dissertation asks the question: are the impacts of karst-related land use regulation on human / social systems significant …

USF Tampa Graduate Theses and Dissertations

Patient care programs such as wellness, preventive care and specifically disease management programs, which target the chronically ill population, are designed to reduce healthcare costs and improve health, while promoting the efficient use of healthcare resources, and increasing productivity. The organizational form adopted by the health plan for these programs, i.e. in-sourced vs. outsourced is an important factor in the success of these programs and the extent to which the core objectives listed above are fulfilled.

Transaction cost economics aims to explain the working arrangement for an organization and to explain why sourcing decisions were made by considering alternate organizational …

The Validity Of Personality Trait Interactions For The Prediction Of Managerial Job Performance, Amy M. Taylor

USF Tampa Graduate Theses and Dissertations

Personality variables have been shown to be significant predictors of job performance (Barrick & Mount, 1991; Tett, Jackson, & Rothstein, 1991). Recent advances in methodology for analyzing personality-job performance relationships indicate that interactions among traits may yield incremental validity. Job types in which performance has been shown to relate to trait interactions include clerical jobs, jobs with high interpersonal components, and jobs in realistic and conventional contexts, (Witt, Burke, Barrick, & Mount, 2002; Burke & Witt, 2002; and Burke & Witt, 2004). This study examined the validity of trait interactions for the prediction of managerial job performance. Hypotheses included a …

Effects Of Nutrients From The Water Column On The Growth Of Benthic Microalgae In Permeable Sediments, Brian P. Darrow

USF Tampa Graduate Theses and Dissertations

In some continental shelf sediments integrated benthic microalgal biomass is greater than the integrated phytoplankton biomass in the overlying water column. In addition, benthic microalgae may account for up to 10% of the primary production responsible for the coastal fishery yield of the eastern United States.

A three-dimensional model of the eastern Gulf of Mexico examines the effects of water-column nutrient sources on the growth of benthic microalgae. To parameterize the exchange of nutrients across the sediment/water interface in these permeable sediments, a non-local exchange submodel was constructed and tested within the framework of the model's grid.

Based on the …

Standing Up With The King: A Critical Look At Stephen King's Epic, Jenifer Michelle D'Elia

USF Tampa Graduate Theses and Dissertations

In this dissertation, it is my intention to show how Stephen King transcends genre, creates and maintains a viable Secondary Reality, and treats capably those literary techniques that critics expect of a serious writer. In addition, I will discuss the ways in which King has secured the loyalty of his Constant Reader. The primary means of my analysis will be through a close reading of the "expanded and uncut" version of The Stand, one of the classics in King's arsenal.

I will begin with an overview of the general set-up in the novel---the start in Arnette, Texas, the actions …

Florida Red Tides: Public Perceptions Of Risk, Sara E. Allen

USF Tampa Graduate Theses and Dissertations

This research integrates the theoretical implications of risk perception, the social amplification of risk, and the role of place-specific contexts, in order to explore the various perceptions surrounding Florida red tides. Florida red tides are a naturally-occurring event, yet most scientists agree that they are increasing in frequency, duration, and severity. This has profound implication for public health, the local economy, and the biological community. While many of the negative impacts are not easily controllable at this time, some of the secondary impacts can be mitigated through individuals' responses. Unfortunately, public perceptions and consequent reactions to red tides have not …

Equilibrium Bidding In Joint Transmission And Energy Markets, Cihan Babayigit

USF Tampa Graduate Theses and Dissertations

Participants in deregulated electric power markets compete for financial transmission rights (FTRs) to hedge against losses due to transmission congestion by submitting bids to the independent system operator (ISO). The ISO obtains an FTR allocation, that maximizes sales revenue while satisfying simultaneous feasibility. This FTR allocation remains in place for a length of time during which the participants compete in the energy market to maximize their total payoff from both FTR and energy markets. Energy markets (bi-lateral, day ahead, real time) continue until the the end of the current FTR period, at which time the participants can choose to modify …

Examining Physicians’ Motivations To Volunteer: An Applied Visual Anthropological Approach, Jess Paul Ambiee

USF Tampa Graduate Theses and Dissertations

In the U.S., the number of persons who cannot afford health care continues to rise. Providing a "safety net" for such persons is becoming increasingly important. Medical professional volunteerism provides access to health care for people who have little or no access to health care otherwise.

At a not-for-profit free health clinic in Tampa, Florida, hundreds of physicians have volunteered their time in an attempt to reduce the health care gap in their community. The clinic sees thousands of persons who have very limited options in regards to their health care. This study investigates the reasons physicians volunteer and the …

Design And Modeling Of A Bistable Spherical Compliant Micromechanism, Joseph Georges Choueifati

USF Tampa Graduate Theses and Dissertations

Compliant bistable mechanisms are mechanisms that have two stable equilibrium positions within their range of motion. Their bistability is mainly due to the elasticity of their members. This thesis introduces a new type of bistable micromechanisms, the Bistable, Spherical, Compliant, four-bar Micromechanism (BSCM). Theory to predict bistable positions and configurations is also developed. Bistabilty was demonstrated through testing done on micro-prototypes. Compared to the mathematical model of the BSCM, Finite element models of the BSCM indicated important qualitative differences in the mechanism's stability behavior and its input-angle-input torque relation. The BSCM has many valuable features, such as: Two stable positions …
