Sedimentation Patterns And Hydrodynamics Of A Wave-Dominated Tidal Inlet: Blind Pass, Florida, David K. Tidwell

USF Tampa Graduate Theses and Dissertations

Blind Pass, a heavily structured wave-dominated tidal inlet on the west central coast of Florida, has undergone substantial morphologic changes in the past 150 years. Initially Blind Pass was a mixed-energy inlet. In 1848 a hurricane opened a new inlet to the north called Johns Pass, which captured a large portion of the tidal prism of Blind Pass. Since then Blind Pass migrated southward until it was structurally stabilized in 1937. The decreasing tidal prism resulted in significant inlet channel filling. The channel has been dredged 12 times since 1937. The present inlet is stabilized by two jetties and a …

Bio-Optical Variability Of Surface Waters In The Northeastern Gulf Of Mexico, Bisman Nababan

USF Tampa Graduate Theses and Dissertations

Bio-optical variability of surface waters in Northeastern Gulf of Mexico (NEGOM) was examined using satellite and in situ data. Relatively high chlorophyll-a concentration (chl>=1 mg m^-3) and high colored dissolved organic mater (a_g443>=0.1 m^-1) were generally observed inshore, near major river mouths, and in plumes of Mississippi River water that extended offshore during the three consecutive summer seasons (1998, 1999, and 2000). River discharge dominated chlorophyll-a concentration variability inshore, particularly near major river mouths. Strong interannual variability in chlorophyll-a concentration was observed inshore from Escambia to Tampa Bay region during …

Associations Between Maternal Depression And Child Social Competence And Display Of Problem Behaviors: A Longitudinal Investigation Of Direct, Indirect And Moderating Effects, Lauren B. Zapata

Postpartum depression is a significant public health problem facing women, children, and families in the United States with an estimated 10-15% of U.S. mothers experiencing an episode of non-psychotic depression within six months of delivery. The purpose of this study was to investigate the associations between maternal depression during the first three years postpartum and child social competence and display of problem behaviors at first grade. The impact of several characteristics of maternal depression were examined including general exposure, timing of initial onset in the postpartum period, severity of symptoms along the trajectory of initial onset, and chronicity of symptoms. …

From Courtly Curiosity To Revolutionary Refreshment: Turkish Coffee And English Politics In The Seventeenth Century, Alexander Mirkovic

USF Tampa Graduate Theses and Dissertations

Why was coffee so fashionable yet so divisive a political symbol during the latter half of the seventeenth century? Historians have offered several answers, including the suggestion that the nascent Orientalism generated its popularity. Undeniably seventeenth century England imported exotic commodities, including coffee and tea, and began to appropriate them for the English culture. Did that also imply maintaining the cultural superiority over the natives? I argue that coffee was symbolically transformed during the political and revolutionary turmoil of the seventeenth century. Coffee was first introduced in the early part of the century to the Stuart court where it was …

A Game Theoretic Framework For Dynamic Task Scheduling In Distributed Heterogeneous Computing Systems, Vasanth Kumar Ramesh

USF Tampa Graduate Theses and Dissertations

Heterogeneous Computing (HC) systems achieve high performance by networking together computing resources of diverse nature. The issues of task assignment and scheduling are critical in the design and performance of such systems. In this thesis, an auction based game theoretic framework is developed for dynamic task scheduling in HC systems. Based on the proposed game theoretic model, a new dynamic scheduling algorithm is developed that uses auction based strategies. The dynamic scheduling algorithm yields schedules with shorter completion times than static schedulers while incurring higher scheduling overhead. Thus, a second scheduling algorithm is proposed which uses an initial schedule generated …

Biomechanical Evaluation Of Injury Severity Associated With Patient Falls From Bed, Bonnie E. Bowers

USF Tampa Graduate Theses and Dissertations

The incidence of falls in the elderly population is a growing concern in the healthcare industry as associated morbidity is high, particularly morbidity associated with falls from bed. Bedrails were implemented as a device intended to reduce the incidence of falls from bed; however, recent evidence may indicate that bedrails contribute to adverse events including entrapment and entanglement. As such, efforts have been made to reduce the use of bedrails and implement alternatives including height adjustable beds and floor mats. An instrumented anthropomorphic test dummy was used in the current study to measure the deceleration profiles of the head, thorax, …

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 …

“They Say That This Clinic Is For Migrants”: Cultural Sensitivity In A Rural Health Center, Nadine I. Ohlinger

USF Tampa Graduate Theses and Dissertations

The growing number of minority populations living in the United States makes it mandatory that all health care organizations seek to be culturally sensitive. There is no consensus on the definition of the term cultural sensitivity. The goal of this thesis is to define what cultural sensitivity means in a rural health center, from the perspective of the staff as well as the Hispanic patient. Anthropological methods, such as participant observation, semi-structured interviews, and archival data analysis, show that the qualities that Hispanic patients value in a clinic are 1) attention, 2) availability of Spanish language, 3) financial assistance, 4) …

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 …

Association Between Area Socioeconomic Status And Hospital Admissions For Childhood And Adult Asthma, Tomas Tamulis

USF Tampa Graduate Theses and Dissertations

Despite an improved understanding of the disease, the prevalence of asthma and asthma-related morbidity continue to rise, particularly among minority and inner-city populations. Despite the growing epidemic of asthma, the surveillance of disease at the state or even local levels is very limited. Such information is very important to identify high-risk population groups and to design more effective community-based preventive interventions or risk management programs that may modify these trends.

The study provided important information about spatial differences by the geographical area of residence and changes in asthma hospital admissions over time in the selected area. Environmental exposure to ambient …

Fantastic Visions: On The Necessity Of Feminist Utopian Narrative, Tracie Anne Welser

USF Tampa Graduate Theses and Dissertations

Works of feminist utopian literature project longing for and predict political change while confronting current social inequities. Often, they effectively interrogate Western models of citizenship and the institutions which reify them, suggesting alternate models. Here, I define Western citizenship as determined by the maintenance of the nation-state through gendered social roles that restrict women to the private sphere and men to the public. This thesis asserts that feminist utopian literature, like politically conscious music, art, and other forms of feminist praxis, is a politically necessary component of feminist consciousness because it facilitates much-needed visions of a more equitable future for …

Alternatively, the system can generate alerting signals without human intervention. Furthermore, recorded historical data can be made available for scientists …

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 …

Comparison Of Hatching Failure In A Wildland And Suburban Population Of The Florida Scrub-Jay (Aphelocoma Coerulescens), Sonya Christine Leclair

USF Tampa Graduate Theses and Dissertations

Egg hatchability has been correlated with many factors, including clutch size, presence of helpers, timing of breeding and predation risk. Hatching failure is higher in a suburban population of Florida Scrub-Jays than in a wildland population, but the reasons for this pattern are unclear. An analysis of long-term demographic data on scrub-jays in both habitats revealed the factors that best explained variation in hatching failure, and an experiment tested whether two potential site factors, ambient temperature and predation risk, could increase hatching failure in the suburbs.

Although a global model was best supported by the data for occurrence of partial …

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 Influence Of Local Rivers On The Eastern Cariaco Basin, Venezuela, Laura Lorenzoni

USF Tampa Graduate Theses and Dissertations

Two oceanographic cruises were conducted during September 2003 and March 2004 in the eastern half of the Cariaco Basin. Specific objectives were to examine the hydrography of the seasonal upwelling plume characteristic of this region, the spatial distribution of particles in the area, and to help determine the source and relative importance of in situ particle production vs. terrigenous particles delivered laterally from the coast.

During September 2003, average surface salinities within the basin were higher (36.6) relative to Caribbean Sea waters outside the basin (35.6). Salinity patterns indicated that the Orinoco and Amazon River plumes did not enter or …

Two Models Of Consensus, Sudarsan Padmanabhan

USF Tampa Graduate Theses and Dissertations

My dissertation titled Two Models of Consensus is based on five arguments. 1. Consensus is asymmetrical. 2. Consensus is partial or limited unanimity. 3. Consensus and democracy do have a concomitant relation. 4. Consensus is not organic to political systems. 5. Consensus depends upon civil society, subsidiarity, and the dominant cultural paradigm of society.

In the first chapter titled "Historical Specificity of the Western Conception of Civil Society" I argue that concept of civil society evolved under certain conditions in a liberal democratic tradition such as shared social imaginaries. As an example of how diversity could lead to hypostatization of …

A Security Constrained Ac Economic Dispatch Framework For Allocation Of Balanced And Unbalanced Financial Transmission Rights, Balaji Rajan

USF Tampa Graduate Theses and Dissertations

In a deregulated power market financial transmission rights (FTR) serve as a mechanism for protecting market participants from price variation resulting from network congestion. Possession of FTRs allows participants to recover congestion related losses resulting from unequal locational marginal prices that arise from out of merit dispatch. There exists different strategies for allocating FTR which are in use in the deregulated market. Designing a comprehensive framework for market specific FTR allocation that includes factors like unbalanced FTR, FTR for losses and AC-OPF is currently a major research issue in the deregulated power industry.

This thesis develops a method for allocation …

An Automatic Code Generation Tool For Partitioned Software In Distributed Computing, Neeta S. Singh

USF Tampa Graduate Theses and Dissertations

In a large class of distributed embedded systems, most of the code generation models in use today target at object-oriented applications. Distributed computing using procedural language applications is challenging because there are no compatible code generators to test the partitioned programs mapped on to the multi-processor system. In this thesis, we design a code generator to produce procedural language code for a distributed embedded system. Unpartitioned programs along with the partition primitives are converted into independently executable concrete implementations. The process consists of two steps, first translating the primitives of the unpartitioned program into equivalent code clusters, and then scheduling …

Design And Fabrication Of A Re-Configurable Micromirror Array For An Optical Microspectrometer, Vandana Upadhyay

USF Tampa Graduate Theses and Dissertations

This thesis presents the design and fabrication of a re-configurable micromirror array which can be used as a component of an optical microspectrometer. In an optical microspectrometer, an array of mechanically positionable micromirrors can be implemented as a reconfigurable exit slit to selectively focus particular wavelengths of a diffracted spectrum onto the detector stage. The signal to noise ratio and response time of an optical microspectrometer can be vastly improved by this technique.

In the approach presented here, a hybrid bulk- and surface- micromachining process is demonstrated for fabrication of a 1XN array of micromirrors. The reconfigurable micromirrors presented here …

Lysogeny: Practical Applications And New Discoveries., Lauren Mcdaniel

USF Tampa Graduate Theses and Dissertations

Part 1:

Prophage induction has been demonstrated to be a sensitive indicator for a wide variety of toxic and mutagenic compounds and, as a consequence, has been utilized for biologically based carcinogen screenings. Fourteen marine bacterial isolates were screened for development into the Marine Prophage Induction Assay (MPIA), for marine samples. The selected isolate (P99-4S3) was identified by 16S rDNA sequencing as Pseudomonas aeruginosa. This isolate demonstrated a log-linear response to increasing dose of mutagens, and sensitivity to known environmental contaminants. Field-testing of the assay over two years demonstrated the MPIA would be a useful screening tool for environmental …

Improving Accuracy In Logarithmic Multiplication Using Operand Decomposition, Mahalingam Venkataraman

USF Tampa Graduate Theses and Dissertations

The arithmetic operations such as multiplication and division in binary number system are computationally complex in terms of area, delay and power. Logarithmic Number Systems (LNS) offer a viable alternative combining the simplicity of fixed point number systems and the precision of floating point number systems. However, the computations in LNS result in some loss of accuracy and thus, are limited to mostly signal processing applications; where in certain amount of error is tolerable. In LNS, the cost of computations can be tradeoff with the level of accuracy needed. The Mitchell algorithm proposed incite[mitchell], is a simple approach commonly used …

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 …
