Low-Level Programming Of A 9-Degree-Of-Freedom Wheelchair-Mounted Robotic Arm With The Application Of Different User Interfaces, Punya A. Basnayaka 2010 University of South Florida

Low-Level Programming Of A 9-Degree-Of-Freedom Wheelchair-Mounted Robotic Arm With The Application Of Different User Interfaces, Punya A. Basnayaka

Graduate Theses and Dissertations

Implementation of C++ and Matlab based control of University of South Florida's latest wheelchair-mounted robotic arm (USF WMRA-II), which has 9 degrees-of-freedom, was carried out under this Master's thesis research. First, the rotational displacements about the 7 joints of the robotic arm were calibrated. It was followed by setting the control gains of the motors. Then existing high-level programs developed using C++ and Matlab for USF WMRA-I were modified for WMRA-II. The required low-level programs to provide complete kinematics of the joint movements to the controller board of WMRA-II (Galil DMC-2183) were developed using C++. A test GUI ...


Do You Have A Permit For That?: Exposing The Pseudo-Public Space And Exploring Alternative Means Of Urban Occupation, Adam Barbosa 2010 University of South Florida

Do You Have A Permit For That?: Exposing The Pseudo-Public Space And Exploring Alternative Means Of Urban Occupation, Adam Barbosa

Graduate Theses and Dissertations

In his 1964 work "One Dimensional Man" Herbert Marcuse describes what he believes to be the de-evolution of industrialized society into the single minded pursuit of commerce. Decades later his hypothesis seems even closer to the truth, as much of our social interaction is now based in spaces that are designed to promote consumption. These spaces are in fact privately owned lots masquerading as public space so as to satiate the populace's desire for "public" interaction without sacrificing their effectiveness as places of commerce. The migration of social interaction into these pseudo-public spaces has also further marginalized the city ...


Examining The Interface Between Alcohol Expectancies, Psychophysiological Reactivity To Alcohol Picture Cues, And Risk For Substance Use Disorders, Ashlee C. Carter 2010 University of South Florida

Examining The Interface Between Alcohol Expectancies, Psychophysiological Reactivity To Alcohol Picture Cues, And Risk For Substance Use Disorders, Ashlee C. Carter

Graduate Theses and Dissertations

The study examined the overlap between cognitive and affective measures of alcohol expectancies as they related to risk for developing alcohol use disorders. It was hypothesized that cognitive-based, paper-and-pencil measures and appetitive psychophysiological reactivity to alcohol cues would correlate and independently correlate to drinking behavior in a sample of college drinkers. It was also hypothesized that genetic risk would impact the relationship between upstream and downstream expectancy measures, given that children of alcoholics displayed blunted reactivity to appetitive cues. A sample of 137 college drinkers (67 males; mean age = 20.23 ± 1.61) reporting a range of drinking behavior (mean ...


On The Involvement Of The Low-Density Lipoprotein Receptor In The Pathogenesis And Progression Of Alzheimer's Disease, Jose Francisco Abisambra Socarras 2010 University of South Florida

On The Involvement Of The Low-Density Lipoprotein Receptor In The Pathogenesis And Progression Of Alzheimer's Disease, Jose Francisco Abisambra Socarras

Graduate Theses and Dissertations

Alzheimer's disease (AD) is the most prevalent form of age-associated dementia. Cholesterol dysregulation is linked with AD onset. Besides age, the most important risk factor associated with AD is the inheritance of the epsilon-4 allele of apolipoprotein E, a cholesterol transporter. In addition, while hypercholesterolemia has been shown to be an independent risk factor for AD, the nature of the cholesterol-AD link is still not clear. This gap in our understanding is partly due to a lack of knowledge about cholesterol metabolism in the central nervous system (CNS). The low-density lipoprotein receptor (LDLR) is the main receptor of apoE ...


Self-Potential Response To Rainfall Changes Over Plugged And Unplugged Sinkholes In A Covered-Karst Terrain, Peter B. Bumpus 2010 University of South Florida

Self-Potential Response To Rainfall Changes Over Plugged And Unplugged Sinkholes In A Covered-Karst Terrain, Peter B. Bumpus

Graduate Theses and Dissertations

For the protection of wetland and water resources it would be beneficial to understand when collapse conduits function as recharge points to the underlying aquifer. Inexpensive, noninvasive methods to detect recharge are desirable. Previous studies show negative self-potential (SP) anomalies over sinkholes that correspond to the expected electrokinetic effects of groundwater flowing downward through a conduit. SP surveys are less labor-intensive than high-resolution 3D GPR and resistivity, and continuous long-term monitoring is possible. However, before SP surveys can be reliable indicators of flow, SP contributions from ET, conductivity changes, redox reactions, thermoelectric effects, cultural noise, and lateral flow must be ...


Noise And Multipath Characteristics Of Power Line Communication Channels, Hasan Basri Çelebi 2010 University of South Florida

Noise And Multipath Characteristics Of Power Line Communication Channels, Hasan Basri Çelebi

Graduate Theses and Dissertations

With the recent developments in technology, information and communication technologies (ICTs) are becoming more widespread and one of the basic building blocks of every humans life. The increasing demand in broadband communication calls for new technologies. Power line communication (PLC) is one of the potential candidates for next generation ICTs. Although communication through power lines has been investigated for a long time, PLC systems were never taken into account seriously because of its harsh communication medium. However, with the development of more robust data transmission schemes, communication over the power lines is becoming a strong alternative technology because of the ...


Analysis Of Two Strategies For Structuring Medicare Reimbursement To Maximize Profitability In Acute Care General Hospitals, James D. Barrington 2010 University of South Florida

Analysis Of Two Strategies For Structuring Medicare Reimbursement To Maximize Profitability In Acute Care General Hospitals, James D. Barrington

Graduate Theses and Dissertations

The healthcare literature sometimes cites Medicare as a negative determinant of hospital profitability. However, a review of Florida acute care short-term general hospital data revealed a subset of profitable hospitals with high percentages of their revenue structure comprised of Medicare reimbursements. Some investigators might contend that these hospitals are just better managed; that hospital profitability is not related to patient mix or payer source. Although good management enhances financial health, there are perhaps other reasons why certain hospitals can become profitable with Medicare as their primary revenue source. Research findings indicate there is wide geographic variability shown for per-capita volumes ...


The Relationship Between Fam5c Snp (Rs10920501) Variability, Metabolic Syndrome, And Inflammation, In Women With Coronary Heart Disease, Jennifer L. Cline 2010 University of South Florida

The Relationship Between Fam5c Snp (Rs10920501) Variability, Metabolic Syndrome, And Inflammation, In Women With Coronary Heart Disease, Jennifer L. Cline

Graduate Theses and Dissertations

The leading cause of death among women is coronary heart disease (CHD), a multifactorial disease with polygenic heritability estimated at 50%. Polymorphisms in the family with sequence similarity 5, member C' (FAM5C) gene have been associated with myocardial infarction (MI), and one single-nucleotide polymorphism (SNP) has partially accounted for linkage in an acute coronary syndrome subset. The linkage peak on FAM5C corresponds directly with a quantitative trait locus for the inflammatory biomarker monocyte chemoattractant protein 1, as well as a linkage peak to metabolic syndrome (MetS). Metabolic syndrome increases the risk of developing CHD, and MI has been positively associated ...


Utilizing Contextualized Reading In Career And Technical Education To Enhance Reading Skills, Alan Duane Darr 2010 University of South Florida

Utilizing Contextualized Reading In Career And Technical Education To Enhance Reading Skills, Alan Duane Darr

Graduate Theses and Dissertations

The traditional education system in the United States developed a goal of sending a high number of students to post secondary schools. The expectation of going to college starts at elementary school and continues through high school and is pushed by the school district's hierarchy. Schools annually publish numbers through the Department of Education at state and national levels of students moving to college. College progression has become such a priority that many students feel they have failed if not college bound. Students not considered academic often move toward vocational education with the intent of post-secondary education to support ...


Rem: Relational Entropy-Based Measure Of Saliency, Kester Duncan 2010 University of South Florida

Rem: Relational Entropy-Based Measure Of Saliency, Kester Duncan

Graduate Theses and Dissertations

The incredible ability of human beings to quickly detect the prominent or salient regions in an image is often taken for granted. To be able to reproduce this intelligent ability in computer vision systems remains quite a challenge. This ability is of paramount importance to perception and image understanding since it accelerates the image analysis process, thereby allowing higher vision processes such as recognition to have a focus of attention. In addition to this, human eye fixation points occurring during the early stages of visual processing, often correspond to the loci of salient image regions. These regions provide us with ...


Articulating Social Change In Puerto Rico: Environmental Education As A Model For Youth Socio-Political Development And Community-Led School Reform, Federico Cintrón-Moscoso 2010 University of South Florida

Articulating Social Change In Puerto Rico: Environmental Education As A Model For Youth Socio-Political Development And Community-Led School Reform, Federico Cintrón-Moscoso

Graduate Theses and Dissertations

Recent attempts at developing an environmental education agenda in public schools emphasize the need to foster greater public awareness about environmental rights, issues, and solutions, while producing citizens with the knowledge and skills needed to address the ecological challenges of contemporary society. However, some scholars have argued that the attempt to integrate environmental principles into the school curricula has created a conflict between the politically-oriented goals of environmental education and the more passive practices of uncritical assimilation and reproduction found in many schools today (Stevenson 2007). Moreover, although there is a need for public schools to take on the challenge ...


Faculty Perspectives On Doctoral Student Mentoring: The Mentor's Odyssey, Carol A. Burg 2010 University of South Florida

Faculty Perspectives On Doctoral Student Mentoring: The Mentor's Odyssey, Carol A. Burg

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 ...


The Effect Of A Reasoning Warning On Faking In Personality Testing For Selection And The Perception Of Procedural Justice, T Ryan Dullaghan 2010 University of South Florida

The Effect Of A Reasoning Warning On Faking In Personality Testing For Selection And The Perception Of Procedural Justice, T Ryan Dullaghan

Graduate Theses and Dissertations

A major concern with using personality tests in the selection process is the prevalence of applicant faking behavior which can influence the rank order of applicants such that fakers are hired at an elevated frequency. This study examined the effects of the detection/consequence warning and a more applicant-friendly warning on faking and perceived procedural justice. I hypothesized that a positive warning (reasoning warning) and a detection/consequence warning would show similar mean personality trait levels compared to honest responses, with all means showing less socially desirable responding than no warning prompt. Results suggested that the detection/consequence warning is ...


A Randomized Trial Of A Dissonance-Induction Intervention To Decrease Tanning Behaviors Among College Females, Sari R. Chait 2010 University of South Florida

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

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 ...


Gatekeeping And Citizen Journalism: A Qualitative Examination Of Participatory Newsgathering, Amani Channel 2010 University of South Florida

Gatekeeping And Citizen Journalism: A Qualitative Examination Of Participatory Newsgathering, Amani Channel

Graduate Theses and Dissertations

For nearly sixty years, scholars have studied how information is selected, vetted, and shared by news organizations. The process, known as gatekeeping, is an enduring mass communications theory that describes the process by which news is gathered and filtered to audiences. It has been suggested, however, that in the wake of online communications the traditional function of media gatekeeping is changing. The infusion of citizen-gathered media into news programming is resulting in what some call a paradigm shift. As mainstream news outlets adopt and encourage public participation, it is important that researchers have a greater understanding of the theoretical implications ...


Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick's 2001, A Space Odyssey And Andrei Tarkovsky's Solaris, Keith Cavedo 2010 University of South Florida

Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick's 2001, A Space Odyssey And Andrei Tarkovsky's Solaris, Keith Cavedo

Graduate Theses and Dissertations

The alien encounter has long been a defining and popular subject of science fiction cinema. However, Stanley Kubrick's 2001: A Space Odyssey (1968) and Andrei Tarkovsky's Solaris (1972) are interrogative, complex, and distinct artistic accomplishments that stand apart from and above the conventional science fiction film. 2001 and Solaris not only represent but complicate the alien/human dichotomy; in the end, they destabilize the dichotomy and even suggest a radical synthesis of the dichotomous elements. 2001 and Solaris further emphasize epistemological and specifically anthropocentric limitations when it comes to understanding the alien or attempting to make sense of ...


Regulation Of Positive Regulatory Domain I-Binding Factor 1 And Its Role In Mantle Cell Lymphoma, Shruti Desai 2010 University of South Florida

Regulation Of Positive Regulatory Domain I-Binding Factor 1 And Its Role In Mantle Cell Lymphoma, Shruti Desai

Graduate Theses and Dissertations

The human positive regulatory domain I binding factor 1 (PRDI-BF1/PRDM1) promotes differentiation of mature B cells into antibody secreting plasma cells. In contrast ectopic expression of PRDM1 in lymphoma cells can lead to inhibition of proliferation or apoptosis. However, little is currently known about the regulation of PRDM1. The first study presented demonstrates that in lymphoma cells stimulation through the B cell receptor rapidly induces endogenous PRDM1 at the level of transcription. This study provides evidence that the PRDM1 promoter is preloaded and poised for activation in the B cell lines. The transcription factor PU.1 is shown to ...


Life In The Florida Everglades: Bioarchaeology Of The Miami One Site, Cristina Echazabal 2010 University of South Florida

Life In The Florida Everglades: Bioarchaeology Of The Miami One Site, Cristina Echazabal

Graduate Theses and Dissertations

The bioarchaeology of prehistoric south Florida has been an area of archaeological interest for the last century because of the interplay between ancient populations and the unique environment of the Everglades. The purpose of this study is to analyze the pathology, demography and mortuary practice of the ancient Southeast Florida aboriginal population at Miami One to assess the similarity of Miami One to other south Florida populations during the prehistoric period. The Miami One site (8DA11) is one of many related sites located along the shore of the Miami River. It was continuously occupied from the Late Archaic (ca.1000 ...


Where Christ Dies Daily: Performances Of Faith At Orlando's Holy Land Experience, Sara B. Dykins Callahan 2010 University of South Florida

Where Christ Dies Daily: Performances Of Faith At Orlando's Holy Land Experience, Sara B. Dykins Callahan

Graduate Theses and Dissertations

This manuscript focuses on performances of place and faith inside the Holy Land Experience (HLE), an edutainment complex nestled in the fantasy nexus of Orlando, Florida. A self-proclaimed living-history museum, the HLE includes animatronic Bible characters and musical dramas. The HLE enacts and embodies evangelical narratives of Christianity and Christian faith, and visitors to the park are asked to join the performances, blurring the distinctions between spectators and professional actors. I argue that visitors' performances of faith invest the space of the HLE with sacredness, while the location and design of the HLE infuses the space with elements of the ...


Who Owns Disability?: An Investigation Into The Politics Of Representation, Shelby Forbes 2010 University of South Florida

Who Owns Disability?: An Investigation Into The Politics Of Representation, Shelby Forbes

Graduate Theses and Dissertations

In this thesis, I show how a community of professionals providing equine therapy to individuals with disabilities discursively make sense of their enterprise. A market metaphor illustrates how disability is constructed as the capital sustaining the livelihood of their industry. Disability is a problem-centered concept. It is generally conceptualized according to a medical model which locates disability within the individual, as opposed to understanding it in a sociological sense which accounts for structural, cultural, and communicative factors. Therapy, on the other hand, is problem-determined-it needs to explicitly determine a problem to be treated in order to sustain itself as an ...
