Perceiving Architecture: An Experiential Design Approach, Ashley Verbanic

USF Tampa Graduate Theses and Dissertations

Perception of the physical environment is largely dependent on a range of criteria which are not always readily identifiable. Such a difficulty to identify how a person perceives an environment creates a situation in which architects and designers can easily neglect this idea of the individual user and their experience.

Through the design of a preschool, this thesis focuses largely on understanding how children and other users perceive and interact with their environments. The design process employed synthesizes user based research and analysis of environmental cues such as light, sound, and smells and their effect on how we interpret a …

Accurate Localization Given Uncertain Sensors, Jeffrey A. Kramer

USF Tampa Graduate Theses and Dissertations

The necessity of accurate localization in mobile robotics is obvious - if a robot does not know where it is, it cannot navigate accurately to reach goal locations. Robots learn about their environment via sensors. Small robots require small, efficient, and, if they are to be deployed in large numbers, inexpensive sensors. The sensors used by robots to perceive the world are inherently inaccurate, providing noisy, erroneous data or even no data at all. Combined with estimation error due to imperfect modeling of the robot, there are many obstacles to successfully localizing in the world. Sensor fusion is used to …

Mubarak’S Machine: The Durability Of The Authoritarian Regime In Egypt, Andrea M. Perkins

USF Tampa Graduate Theses and Dissertations

The Egyptian authoritarian regime is a mammoth machine created and headed by President Hosni Mubarak as an instrument for the exercise of his own power. His ability to influence every facet of the character of Egypt lies in his previous career experience, the involvement in politics of his immediate family, his commitment to unpopular but lucrative foreign policies, and the bureaucratic obstacle course he created for opposition entities to navigate.

Through persistent efforts to prepare himself for national leadership prior to gaining power, then to consolidate his power in the institutions of Egypt, Mubarak has built a state organization with …

Translating Neil Simon‘S The Dinner Party: A Linguistic Approach, Brigitte Philippe

USF Tampa Graduate Theses and Dissertations

Translation is a challenge. More than just words, languages are ways of looking at the world and these unique perspectives make it hard to talk about a reality which might not exist in the language in which we are trying to express it. It becomes a greater challenge when one tackles theater as it is not a genre translation theories have studied extensively, which means the translator cannot rely on tradition. And the challenge reaches a new level when it comes to translating humor: humor is linguistically and culturally determined. Indeed, languages do not express humor using the same tools …

Exploratory Analysis Of Maintenance In Behavioral Parent Training, Claudia Villari

USF Tampa Graduate Theses and Dissertations

A two-part study explored the maintenance effect of Behavioral Parent Training (BPT) featuring multi-component treatments by examining one year follow-up data from a larger study. Participants were ten parents of children (ages 3-5) with developmental disabilities and severe problem behaviors. Parents were also identified as having high levels of pessimism. BPT featuring multi-component treatments was provided in two conditions: Positive Behavior Support (PBS) and Positive Family Intervention (PFI). PBS included a standardized protocol to teach parents how to conduct a functional assessment, develop and implement a multi-component treatment, which includes the following strategies: prevention, teaching replacement skills, and managing consequences. …

Empty Streets In The Capital Of Modernity: Formation Of Lieux De Mémoire In Parisian Street Photography From Daguerre To Atget, Sabrina Lynn Hughes

USF Tampa Graduate Theses and Dissertations

This study proposes the existence of lieux de mémoire in the photographs of Eugene Atget (1857-1927). My framework is based on historian Pierre Nora's definition: a lieu de mémoire is an object or idea which has become a symbolic stand-in for a community's memorial heritage. I suggest that Atget's photographs of the streets of old Paris, in concert with an empty-street aesthetic function as lieux de mémoire for their primary audience, antiquarians and professional archivists who specialized in old Paris.

According to Nora's structure, identification of a lieu de mémoire requires first the establishment of a historical tradition. In the …

Descartes' Bête Machine, The Leibnizian Correction And Religious Influence, John Voelpel

USF Tampa Graduate Theses and Dissertations

René Descartes’ 1637 “bête machine” characterization of nonhuman animals has assisted in the strengthening of the Genesis 1:26 and 1: 28 disparate categorization of nonhuman animals and human animals. That characterization appeared in Descartes’ first important published writing, the Discourse on the Method, and can be summarized as including the ideas that nonhuman animals are like machines; do not have thoughts, reason or souls like human animals; and thus, cannot be categorized with humans; and, as a result, do not experience pain or certain other feelings. This characterization has impeded the primary objective of environmental ethics - the extension of …

Comparing The Effectiveness Of Behavioral Contracts That Use Function Based Reinforcers Versus Highly Preferred Items For Attention Maintained Behaviors, Dánica M. Diáz

USF Tampa Graduate Theses and Dissertations

Behavioral contracts were used to reduce the socially inappropriate and stigmatizing behaviors of adult men diagnosed with an intellectual disability. All three participants were residing in an intensive residential habilitation facility and receiving 24 hour supports due to the intensity of their problem behaviors. A multiple baseline across subjects with a series of reversals within the intervention phase was used to compare and evaluate the effectiveness of two types of behavioral contracts: one based on the function of the behavior and the other based on highly preferred items. Brief functional analyses were conducted to determine the function of the participants' …

Immune Redistribution To Skin In Wild And Domesticated Songbirds, Joshua Ryan Kuhlman

USF Tampa Graduate Theses and Dissertations

Implantation of dental sponges under the skin of lab rodents has been used to evaluate whether acute stress enhances leukocyte infiltration to a surgical site. First, I replicated this technique in house sparrows to test whether transient stressors cause similar immunoredistribution (i.e., movement of immune cells out of circulation and to the periphery) in a wild animal. As placement into captivity alone may serve as a stressor to wild animals, I compared sponge infiltration over different periods of captivity. Second, I compared how domestication affects immunoredistribution by comparing results of wild sparrows to domesticated zebra finches. Zebra finches were chosen …

Semi-Supervised Self-Learning On Imbalanced Data Sets, John Nicholas Korecki

USF Tampa Graduate Theses and Dissertations

Semi-supervised self-learning algorithms have been shown to improve classifier accuracy under a variety of conditions. In this thesis, semi-supervised self-learning using ensembles of random forests and fuzzy c-means clustering similarity was applied to three data sets to show where improvement is possible over random forests alone. Two of the data sets are emulations of large simulations in which the data may be distributed. Additionally, the ratio of majority to minority class examples in the training set was altered to examine the effect of training set bias on performance when applying the semi-supervised algorithm.

Spanish Spelling Errors Of Emerging Bilingual Writers In Middle School, Diana Julbe-Delgado

USF Tampa Graduate Theses and Dissertations

In spite of the significant growth in the Spanish-English bilingual population, there has not been sufficient research on cross-language effects, or how language transfer may affect important components of literacy, such as spelling. Many studies have focused on the influence of Spanish on the acquisition of English spelling skills; however, few studies have focused on how the acquisition of English influences Spanish spelling. The purpose of this investigation was to study the spelling errors of bilingual adolescents as they learn English.

A total of 20 bilingual Spanish-English students in grades 6 through 8 (ages 11 to 14 years) were selected …

Parallel Genetic Algorithm Engine On An Fpga, Mark La Spina

USF Tampa Graduate Theses and Dissertations

The field of FPGA design is ever-growing due to costs being lower than that of ASICs, as well as the time and cost of development. Creating programs to run on them is equally important as developing the devices themselves. Utilizing the increase in performance over software, as well as the ease of reprogramming the device, has led to complex concepts and algorithms that would otherwise be very time-consuming when implemented on software. One such focus has been towards a search and optimization algorithm called the genetic algorithm. The proposed approach is to take an existing application of the genetic algorithm …

Re-Composition: Considering The Intersections Of Composition And Creative Writing Theories And Pedagogies, Danita Berg

USF Tampa Graduate Theses and Dissertations

Maintaining composition studies and creative writing as discrete disciplines may not be in the best interests of either field. But so long as the majority of scholars and practitioners of either field remain largely uninformed about one another, it is unlikely that any progress toward conjoining the two fields will occur. Various important and constructive efforts have been made for more than thirty years to establish a scholarly, interdisciplinary community that dedicates itself to examining points of intersection between composition and creative writing. Initially, such efforts appear to attract the attention from the broader communities of each discipline. Before long, …

Polarization Of Galvanic Point Anodes For Corrosion Prevention In Reinforced Concrete, Margareth Dugarte

USF Tampa Graduate Theses and Dissertations

The polarization performance of two types of commercial galvanic point anodes for protection of reinforced steel around patch repairs was investigated. Experiments included measurement of the polarization history of the anode under constant current impressed by galvanostatic circuits and in reinforced concrete slabs. The tests revealed, for both types of anodes, a potential-current function (PF) indicating relatively little anodic polarization from an open circuit potential at low current levels, followed by an abrupt increase in potential as the current approached an apparent terminal value. Aging of the anodes was manifested by a continually decreasing current output in the concrete tests, …

Optimizing The Imaging Of Multiple Frequency Gpr Datasets Using Composite Radargrams: An Example From Santa Rosa Island, Florida, Stuart W. Bancroft

USF Tampa Graduate Theses and Dissertations

Acquiring GPR data at multiple frequencies is useful because higher-frequency profiles have better spatial resolution, although they suffer from reduced depth penetration. Lower-frequencies can generally resolve to greater depths, but at the cost of spatial resolution. For concise presentation of GPR data, it would be useful to combine the best features of each profile into a composite radargram. This study explores effective ways to present GPR data acquired at multiple frequencies. An example is shown from a survey of hurricane overwash deposits from Santa Rosa Island, Florida.

The methodology used to create a composite radargram is dependent on which of …

An Investigation On Radiometric Measurements Of Subterranean Heat Sources, Rakesh Shirodkar

USF Tampa Graduate Theses and Dissertations

With global warming on the rise and the urge for conserving our natural resources, it becomes very important that proper steps are taken to protect our natural resources and utilize them efficiently. Forest fires are one of the many issues on the charts towards protection of natural resources. The catastrophic aftermaths caused by forest fires are known to all. The causes for these fires could be known/unknown natural causes or human intervention. Remote sensing techniques use the electromagnetic radiation in the RF/Microwave region, emitted from an object. The amount of energy emitted from an object depends on its present conditions, …

Spring Design Optimization With Fatigue, John L. Porteiro

USF Tampa Graduate Theses and Dissertations

The purpose of this work is to look into the fundamental issues regarding spring design and develop a new, easy to use software program that would allow for optimal, flexible spring designs. Most commercial programs that address this function are basic and do not allow the designer much control over the variables hindering design. This is so because most programs start from the premise that the spring is a general purpose part of the system or that other design parameters can be altered to accommodate the chosen spring. In cases where this is not so, such as in hydraulic cartridge …

Empirical comparisons between the constructed and GBM models are outlined.

By analyzing the residual errors, we observed the nonlinearity in the data …

Lithic Technology And Obsidian Exchange Networks In Bronze Age Sardinia, Italy (Ca. 1600-850 B.C.), Kyle P. Freund

USF Tampa Graduate Theses and Dissertations

The Sardinian Bronze Age (Nuragic period) and the factors which created and maintained an island-wide identity as seen through the presence of its distinctive nuraghi have received considerable attention; however the amount of research directly related to the stone tools of the era has been relatively limited despite the wealth of knowledge it is capable of yielding. This thesis hopes to contribute to Sardinian archaeology through the study of ancient technology, specifically obsidian lithic technology, by combining typological information with source data gleaned from the use of X-ray fluorescence spectrometry (XRF). These data are integrated with statistical analyses breaking down …

Development And Testing Of A New C-Based Algorithm To Control A 9-Degree-Offreedom Wheelchair-Mounted-Robotic-Arm System, Ana Catalina Torres Rocco

USF Tampa Graduate Theses and Dissertations

A Wheelchair-Mounted Robotic Arm (WMRA) was designed to aid people with limited or no upper-limb usage to accomplish activities of daily living (ADLs). The primary objective of this research was to enhance the performance of the WMRA by improving the communication protocols and functions between the hardware and software used for its control.

Previously, the control algorithm of the robotic arm was tested in simulation and in the physical arm. These implementations required a combination of Matlab and C++ language and introduced some software instability under Windows operating system. To improve the performance of the WMRA, the programs for hardware …

Influence Of Crosslink Density On Swelling And Conformation Of Surface-Constrained Poly(N-Isopropylacrylamide) Hydrogels, Ryan S. Cates

USF Tampa Graduate Theses and Dissertations

A stimuli-responsive microgel is a three-dimensional polymer network that is able to absorb and expel a solvent (commonly water). These materials are unique in the fact that their sponge-like behavior can be actuated by environmental cues, like temperature, ion concentration, pH, and light. Because of the dynamic properties of these materials they have found applications in drug-delivery systems, micro-assays, selective filtration, artificial muscle, and non-fouling surfaces. The most well-known stimuli-responsive polymer is Poly(N-isopropylacrylamide) or PNIPAAm and it experiences a switchable swelling or deswelling over a critical temperature ( T_c=~32°C). Below the critical temperature, the gel begins mixing with …

Optimization Of A Ball-Milled Photocatalyst For Wastewater Treatment Through Use Of An Orthogonal-Array Experimental Design, Bradley J. Ridder

USF Tampa Graduate Theses and Dissertations

The effects of various catalyst synthesis parameters on the photocatalytic degradation kinetics of aqueous methyl orange dye are presented. The four factors investigated were: i) InVO₄ concentration, ii) nickel concentration, iii) InVO₄ calcination temperature, and iv) ballmilling time. Three levels were used for each factor. Due to the large number of possible experiments in a full factorial experiment, an orthogonal-array experimental design was used. UV-vis spectrophotometry was used to measure the dye concentration. The results show that nickel concentration was a significant parameter, with 90% confidence. The relative ranking of importance of the parameters was nickel concentration > InVO …

Faculty Perspectives On Doctoral Student Mentoring: The Mentor‘S Odyssey, Carol A. Burg

USF Tampa Graduate Theses and Dissertations

In recent years, mentoring has emerged as a research domain, however, the preponderance of mentoring research has been situated first, in the business or organizational settings and second, in the K-12 educational setting, focusing on protégé experiences, using quantitative survey instruments to collect data. Thus, mentoring research literature includes a paucity of formal studies in the arena of graduate education.

Situated in the higher education setting, this study investigated the perspectives of faculty-mentors who provided mentoring to doctoral students who completed the doctoral degree, employing the qualitative research methodology known as phenomenology, as an orthogonal but complimentary epistemology to previous …

Corrosion Of Epoxy-Coated Reinforcement In Marine Bridges With Locally Deficient Concrete, Kingsley Lau

USF Tampa Graduate Theses and Dissertations

Epoxy-coated rebar (ECR) has been used in approximately 300 Florida bridges, in an attempt to control corrosion of the substructure in the splash-evaporation zone. Early severe ECR corrosion was observed in the substructure of several Florida ECR bridges (Group 1) where the substructure was built with permeable concrete of high apparent chloride diffusivity D_App. Other ECR bridges built during the same period and having similar D_App were projected to show corrosion damage starting on the following decade. Examination of several of those bridges (Group 2) confirmed that projection. Other recently examined Florida ECR bridges (Groups 3 and …

Total Internal Reflection Holographic Microscopy (Tirhm) For Quantitative Phase Characterization Of Cell-Substrate Adhesion, William Mason Ash Iii

USF Tampa Graduate Theses and Dissertations

Total Internal Reflection Holographic Microscopy (TIRHM) combines near-field microscopy with digital holography to produce a new form of near-field phase microscopy. Using a prism in TIR as a near-field imager, the presence of microscopic organisms, cell-substrate interfaces, and adhesions, causes relative refractive index (RRI) and frustrated TIR (f-TIR) to modulate the object beam's evanescent wave phase front. Quantitative phase images of test specimens such as Amoeba proteus, Dictyostelium Discoideum and cells such as SKOV-3 ovarian cancer and 3T3 fibroblasts are produced without the need to introduce stains or fluorophores. The angular spectrum method of digital holography to compensate for …

Implicit Affect And Alcohol Outcome Expectancies, John M. Ray

USF Tampa Graduate Theses and Dissertations

Expectancy theory provides a useful framework within which to examine the link between cognitive representations of anticipated alcohol related outcomes and affective processes that ought to shape behavior at the level of implicit, or automatic, processing. The role of affect in alcohol expectancies is an important one as it reflects the approach-avoid contingency associated with reward learning presumed to underlie addictive processes. This study examined the relationship between affect and expectancy operation by using suboptimally presented alcohol related cues to prime affectively congruent evaluations of otherwise unrelated targets. Hypotheses predicted that drinkers who reported higher positive and arousing expectancies for …

Statistical Learning And Behrens-Fisher Distribution Methods For Heteroscedastic Data In Microarray Analysis, Nabin K. Manandhr-Shrestha

USF Tampa Graduate Theses and Dissertations

The aim of the present study is to identify the di®erentially expressed genes be- tween two di®erent conditions and apply it in predicting the class of new samples using the microarray data. Microarray data analysis poses many challenges to the statis- ticians because of its high dimensionality and small sample size, dubbed as "small n large p problem". Microarray data has been extensively studied by many statisticians and geneticists. Generally, it is said to follow a normal distribution with equal vari- ances in two conditions, but it is not true in general. Since the number of replications is very small, …

Bird Communities Of Isolated Cypress Wetlands Along An Urban Gradient In Hillsborough County, Florida, Nathaniel L. Goddard

USF Tampa Graduate Theses and Dissertations

Migratory bird communities are sensitive to landscape alteration. Urban development significantly impacts bird communities on breeding grounds, as well as en-route during migration. One current theory is that Neotropical migratory birds are not limited by breeding or wintering habitat constraints but by food and habitat availability along major migration routes. The eastern flyway is the route taken by neotropical land-birds through eastern North America that follows coastal areas denoted by intense urban development. Coastal areas funnel birds to major departure points along the northern coast of the Gulf of Mexico and the western coast of Florida.

Birds were monitored for …

An Interpretive Policy Analysis Of Bullying Law And The Development Of Bullying Policy In A Central Florida School District, Scott D. Richman

USF Tampa Graduate Theses and Dissertations

Bullying has been an issue in schools and became a major concern for school leaders over the past two decades. Olweus (1993) defined three characteristics of bullying behavior: intent to harm another, repeated offenses, and a perceived or real power imbalance. This study examined the law's provisions concerning bullying in schools; specifically examining the Florida Jeffrey Johnston Stand Up for All Student Act (2008), and the required policy implemented in Hillsborough County Public Schools (HCPS). Discourse theory framed the study, as defined by Habermas (1996) and the derivative Interpretive Policy Analysis was used to analyze the district policy, as defined …

Writing To (Re)New Orleans: The Post-Hurricane Katrina Blogosphere And Its Ability To Inspire Recovery, Daisy Pignetti

USF Tampa Graduate Theses and Dissertations

Nearly every website or software application these days features a feed to subscribe to, a network to join, or a social timeline to track—all of which do their part to influence public opinion, promote products, and bring people closer together. Being a blogger since 2003 exposed me to these user-generated trends, but never did I expect my blog space, or any others, to play such an important role in my emotional well-being; not until Hurricane Katrina hit. Sharing my story as a transplanted New Orleanian watching the disaster unfold from afar in a public forum quickly linked me to other …
