Enhanced Co2 Storage In Confined Geologic Formations, Roland Tenjoh Okwen

USF Tampa Graduate Theses and Dissertations

Many geoscientists endorse Carbon Capture and Storage (CCS) as a potential strategy

for mitigating emissions of greenhouse gases. Deep saline aquifers have been reported to

have larger CO

2 storage capacity than other formation types because of their availability

worldwide and less competitive usage. This work proposes an analytical model for screening

potential CO

2 storage sites and investigates injection strategies that can be employed to

enhance CO

2 storage.

The analytical model provides of estimates CO

An Exploratory Analysis Of The Ecological Validity Of A Performance-Based Assessment Of Attention, Eun- Yeop Lee

USF Tampa Graduate Theses and Dissertations

Executive functions impact everyday functioning. An individual’s ability to adapt

to and navigate their physical and social environments is largely determined by the ability

to organize oneself, to plan and to coordinate activities. Despite the wide variety of

cognitive tests that assess various aspects of executive function, there has been little work

to validate the use of these measures in predicting real world functioning (Sbordone,

Seyranian, & Ruff, 2000), particularly in children where characterization of executive

function is less specified. Evaluating the ecological validity of neuropsychological tests

has become an increasingly important topic over the past decade (Chaytor & Schmitter- …

Literary Bodies: The Novel As Experience, Britt Dienes

USF Tampa Graduate Theses and Dissertations

For my MA thesis I propose to examine a series of novels that combine motifs of the body with structural and linguistic experimentation that parallels the state of the bodies within the text. Using Tsitsi Dangarembga's 1988 "bodybildungsroman" Nervous Conditions, Sherley Anne Williams' 1986 neo -slave narrative Dessa Rose, Samuel Beckett's 1938 existential novel Murphy, Vikram Seth's 1986 poetic novel Golden Gate, and Vladimir Nabokov's 1962 poetic novel Pale Fire, I will argue that these texts portray the body as a readable space of culture, a legible site of conflict or creation.

I contend that these novels …

Martian Modules: Design Of A Programmable Martian Settlement, Craig A. Trover

USF Tampa Graduate Theses and Dissertations

The evolution of human beings is marked

by adaptation. The ability to adapt to and

manipulate our environment is one definer of

intelligence, and ours is unique among life

on Earth. Since moving off of the African

Continent, humans have migrated to inhabit

every part of the Earth. Human existence

and perpetuity in the universe depends upon

the success of this adaptation, and inevitably,

migrating off of this planet. The technological

advances being developed today will change

our way of life, and enable people to travel to

and live permanently on the Moon and Mars.

This study involves the architectural …

A Randomized Trial Of A Dissonance-Induction Intervention To Decrease Tanning Behaviors Among College Females, Sari R. Chait

USF Tampa Graduate Theses and Dissertations

Sun exposure is implicated in the majority of skin cancer cases so it is important to identify interventions that successfully decrease young people's tanning behaviors and increase their sun protection behaviors. Research suggests that interventions that focus on the more immediate appearance related effects of tanning, rather than on future health risks, may be more effective in altering UV-related behaviors. Dissonance induction is a strategy that has been used to successfully alter other health-related behaviors. This study sought to determine if a dissonance induction intervention might be similarly successful in changing UV-related behaviors. The study yielded mixed findings. Relative to …

Hunger Of The Body, Hunger Of The Mind: The Experience Of Food Insecurity In Rural, Non-Peninsular Malaysia, Elizabeth Elliott Cooper

USF Tampa Graduate Theses and Dissertations

Supplementary feeding continues to be a widespread strategy for child health promotion though its efficacy remains contested. The long-standing, Malaysian national food assistance program for children - Program Pemulihan Kanak-Kanak Kekurangan Zat Makanan (PPKZM) - fits this pattern, receiving severe criticism for its limited impact on child nutritional status. Still, the program remains, producing a seeming paradox and prompting questions of how it fits into (1) the larger political context of national health policy and (2) more localized village and clinic environments. This research combines historical inquiry with the in-depth, ethnographic study of two predominantly Malay coastal villages in Malaysian …

Autonomous Vertical Autorotation For Unmanned Helicopters, Konstantinos Dalamagkidis

USF Tampa Graduate Theses and Dissertations

Small Unmanned Aircraft Systems (UAS) are considered the stepping stone for the integration of civil unmanned vehicles in the National Airspace System (NAS) because of their low cost and risk. Such systems are aimed at a variety of applications including search and rescue, surveillance, communications, traffic monitoring and inspection of buildings, power lines and bridges. Amidst these systems, small helicopters play an important role because of their capability to hold a position, to maneuver in tight spaces and to take off and land from virtually anywhere. Nevertheless civil adoption of such systems is minimal, mostly because of regulatory problems that …

Enhancing Nature Of Science Understanding, Reflective Judgment, And Argumentation Through Socioscientific Issues, Brendan E. Callahan

USF Tampa Graduate Theses and Dissertations

There is a distinct divide between theory and practice in American science education. Research indicates that a constructivist philosophy, in which students construct their own knowledge, is conductive to learning, while in many cases teachers continue to present science in a more traditional manner. This study sought to explore possible relationships between a socioscientific issues based curriculum and three outcome variables: nature of science understanding, reflective judgment, and argumentation skill. Both quantitative and qualitative methods were used to examine both whole class differences as well as individual differences between the beginning and end of a semester of high school Biology …

“The Bitch,” “The Ditz,” And The Male Heroes: Representations Of Feminism And Postfeminism In Campaign 2008, Dana Schowalter

USF Tampa Graduate Theses and Dissertations

This study is a textual analysis of the mainstream media coverage of the 2008 U.S. Presidential election, surveying more than 1,000 news stories featuring Clinton, Palin, Obama, Biden and McCain published between January 1, 2007 and November 11, 2008. The central findings of this study are twofold: first, mainstream news sources continue to use stereotypical and sexist news frames that describe women in ways that are at odds with the criteria we set for being a good president; and second, feminism is characterized in ways that divorce the ideas of the movement from the activism necessary to overcome existing injustices. …

Humor And Attitude Toward Homosexuals: The Case Of Will & Grace, Heather Cribbs

USF Tampa Graduate Theses and Dissertations

Data collected from a survey questionnaire disseminated to college students was used to examine the relationship between humor in the mass media on audience attitude. This research study attempted to link the comedic nature of media with a heightened tolerance toward unpopular messages by looking specifically at the show Will & Grace. Results supported the hypothesized positive relationship between humor on attitudes toward the show, as well as attitudes toward real life homosexuals. In addition, distraction and interpersonal communication served as mediators between humor and attitudes. Results supported positive relationships between humor and both distraction and interpersonal communication, and supported …

Evaluating Dissolved Oxygen Regimes Along A Gradient Of Human Disturbance For Lotic Systems In West-Central Florida, Daniel G. Hammond

USF Tampa Graduate Theses and Dissertations

Land uses dominated by human activity can have a significant effect on ecological processes. In Florida, oxygen depletion is the most common impairment in lake, stream, and coastal water bodies. The continual growth and development in Florida, along with a conversion to more human intense land uses warrants study and discussion on impacts to dissolved oxygen regimes along a gradient of human disturbance. This research study is designed to identify observable trends in dissolved oxygen regimes along a gradient of increasing human intensity.

Twenty-six stations in the Tampa Bay area were selected to represent lotic systems in west-central Florida. Data …

Development Of A Mangrove Quality Index In Tampa Bay, Florida, Monetta S. Wilson

USF Tampa Graduate Theses and Dissertations

Mangroves are an important resource. They provide a breeding ground for commercially and recreationally important fish, protect shorelines from erosion and improve coastal water quality. Historically, mangroves were undervalued, leading to a loss of 35% of mangroves worldwide and 44% in Tampa Bay due to anthropogenic stressors. Efforts to protect and restore mangroves have led to a variety of management programs. In Tampa Bay the main management program is the Tampa Bay Estuary Program (TBEP). The program has identified the need for simple and easy to use assessment tools to track mangrove quality and aid in mangrove quality. There are …

The Subjective Experience Of Pms: A Sociological Analysis Of Women’S Narratives, Christiana B. Chekoudjian

USF Tampa Graduate Theses and Dissertations

The phenomenon known as premenstrual syndrome (PMS) has been researched across many disciplines including Psychology, Women's Health, Women's Studies and Sociology. It has been researched as a personal issue, a health issue, a psychological issue, and a political issue. Underlying these approaches to the study of PMS are two basic paradigms: the medical model and the social constructionist model. A rather polarized debate has emerged between the two. While both approaches have contributed to research on PMS, neither paradigm has focused particular attention on what PMS is and what it means from the perspective of the women who experience it. …

Speech Recognition Software For Language Learning: Toward An Evaluation Of Validity And Student Perceptions, Deborah Cordier

USF Tampa Graduate Theses and Dissertations

A renewed focus on foreign language (FL) learning and speech for communication has resulted in computer-assisted language learning (CALL) software developed with Automatic Speech Recognition (ASR). ASR features for FL pronunciation (Lafford, 2004) are functional components of CALL designs used for FL teaching and learning. The ASR features available with the TeLL me More French software provides pronunciation, intonation and speaking practice and feedback. ASR features are examined quantitatively through French student performance of recorded ASR-scored speech and compared with human raters of the same produced speech samples. A comparison of ASR scores to human raters considers the validity of …

Improving Ad-Hoc Team Performance Using Video Games, Jeff David Craighead

USF Tampa Graduate Theses and Dissertations

This dissertation examined the effects of distributed, multiplayer training video games on the performance of distributed teams of robot operators. Two hypotheses were tested, the first hypothesis stated that online, game-based team training will improve the performance of an ad-hoc team versus an ad-hoc team formed of individually trained teammates. The second hypothesis stated that the fractal dimension of a robot's path can be used as an indicator of its operator's skill. Forty-one volunteers participated in an experiment in which they played a distributed, online training game which showed them the basics of operating an Inuktun Extreme VGTV for a …

Establishing Creative Writing Studies As An Academic Discipline, Dianne J. Donnelly

USF Tampa Graduate Theses and Dissertations

The discipline of creative writing is charged "as the most untheorized, and in that respect, anachronistic area in the entire constellation of English studies (Haake What Our Speech Disrupts 49). We need only look at its historical precedents to understand these intimations. It is a discipline which is unaware of the histories that informs its practice. It relies on the tradition of the workshop model as its signature pedagogy, and it is part of a fractured community signaled by its long history of subordination to literary studies, its lack of status and sustaining lore, and its own resistance to reform. …

Six Fifth Grade Students Experiences Participating In Active Gaming During Physical Eduction Classes, Lisa Witherspoon Hansen

USF Tampa Graduate Theses and Dissertations

As technology and sedentary lifestyles have become an integral part of children's lives, so too has the prevalence of childhood obesity. Although video games are often associated with influencing sedentary behaviors, active gaming is a new genre that requires children to become physically active while playing the games. In this inquiry I explored six fifth grade students' experiences participating in active gaming in physical education classes for 30 minutes, twice weekly, during an eight week (16 sessions) study. I used qualitative methods including interviews, journal entries, and observational field notes. Analysis of data revealed students have a "Persistence to Game" …

The Effect Of Celebrity Endorsements On Gift-Giving Purchases: An Application Of The Elaboration Likelihood Model, Christine Anghel

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to determine how effective celebrity endorsements are in regards to the type of gift purchase one decides to make (i.e., buying for someone who has a high significant meaning to the buyer, such as a best friend, versus buying for someone who has a low significant meaning to the buyer, such as a casual friend). The study seeks to extend upon the anthropology research exploring gift-giving and marketing research exploring celebrity endorsements by applying the tenants of the Elaboration Likelihood Model (ELM). This study uses an experimental procedure in order to determine the effect …

This reform technique engaged students to work on guided inquiry activities while working cooperatively in small groups, led by undergraduate peer leaders. These sessions were video recorded and transcribed. The data was evaluated using grounded theory methods of analysis. This study examined the dialog between students and peer leaders, paying specific attention to question types and observed …

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 …

This study examined the effects of a parent training program teaching discrete trial teaching (DTT) and incidental teaching (IT) methods using a parent training manual. Three families with children between the ages of 5-6 diagnosed with Autism Spectrum Disorder (ASD) participated. Both parents received parent training although Parent A received training from the experimenter and Parent B received training from Parent A. The parents taught their children one skill each from three categories: communication, self-care routines and a household expectation. This study sought to expand upon the literature in the realm of combining DTT and IT as well as adding …

Making And Keeping The Peace: An Analysis Of African Union Efficacy, Nicholas Temple

USF Tampa Graduate Theses and Dissertations

The African Union (AU) has pledged to create a continent of peace and solidarity. However, dozens of socio-ethnic conflicts occur across the continent despite the AU's best efforts to prevent them. In this thesis, case studies of Darfur and Western Sahara were used to assess the efficacy of the AU in the realm of peacemaking and peacekeeping. Within each of these studies, AU impediments to peacemaking and peacekeeping on financial, political, and socio-cultural fronts were analyzed. The findings suggest that while socio-cultural conflict continues to proliferate, the AU has neither the financial resources nor the political clout to meet peacemaking …

Studying The Effects Of Motivation On The Emergence Of Untrained Verbal Operants, Alysia Gilliam

USF Tampa Graduate Theses and Dissertations

In Skinner's (1957) analysis of verbal behavior, the tact and mand are suggested to be functionally independent verbal operants. Many studies evaluating the verbal operants have provided results consistent with Skinner's notion of functional independence. For example, previous studies have yielded results showing that responses taught as tacts failed to emerge as mands unless they were directly trained as such. However, in many of the studies evaluating the functional independence of the verbal operants it is unclear whether the mand conditions were designed to actually evaluate that response function. The current study replicated and extended the findings of Wallace, Iwata, …

An Inconsistency-Based Approach For Sensing Assessment In Unknown Environments, Jennifer Diane Gage

USF Tampa Graduate Theses and Dissertations

While exploring an unknown environment, an intelligent agent has only its sensors to guide its actions. Each sensor's ability to provide accurate information depends on the environment's characteristics. If the agent does not know these characteristics, how can it determine which sensors to rely on? This problem is exacerbated by sensing anomalies: cases where sensor(s) are working but the readings lead to an incorrect interpretation of the environment, e.g. laser sensors cannot detect glass. This work addresses the following research question: Can an inconsistency-based sensing accuracy indicator, which relies solely on fused sensor readings, be used to detect and …

In this school district, school psychologists are required to complete documentation for Medicaid reimbursement to the district, but were inconsistent in …

Software Automation For Measurement-Based Behavioral Models Of Microwave, Daniel Sosa Martin

USF Tampa Graduate Theses and Dissertations

This thesis presents a study and implementation of several measurement procedures used to efficiently generate non-linear measurement-based behavioral models primary for microwave amplifiers. Behavioral models are a solution for representing devices that can present linear and/or non-linear behavior when little or no information about the internal structure is known. Measurement-based behavioral models are an advantage since they can be extracted from a direct measurement of the device. This work addresses some of the challenges of these types of measurements. A set of software modules has been produced that combine several modern techniques to efficiently generate practical models using equipment commonly …
