Framework For Self Sustaining Eco-Village, Eric Holtgard

USF Tampa Graduate Theses and Dissertations

Why are modern American cities fundamentally dependant on outsourced resources and dirty power? Why can't modern cities support themselves and their inhabitants without relying on resources from half way across the world? Even within the city itself, community neighborhoods are disconnected and bisected by massive expanses of life endangering highways. Why can't we wake up and open our eyes to the urban reality we are creating for future generations. Future cities must look past immediate gain and focus on long term sustainability rather than compiling L.E.E.D. points or making a selfish profit.

Sustainable Infrastructure is the first step towards freeing …

The Participation Of Ngos In Healthcare: The Case Of Pediatric Cancer Treatment In Argentina, Cecilia Vindrola Padros

USF Tampa Graduate Theses and Dissertations

The deterioration of the Argentine public health system has lead to an increase in non-governmental involvement in the provision of health services. The emerging relationship between these sectors is filled with tensions, contradictions, and negotiations, reflecting the historical trajectory of non-governmental organizations (NGOs) and the transformations of the public health system. These problems are specifically evident in programs that focus on pediatric oncology treatment due to the fact that ideas about childhood, chronic disease, and mortality construct an unusual collaborative framework between governmental and non-governmental healthcare professionals. Pediatric cancer contradicts traditional notions of childhood; it points out the ambivalences associated …

Multimodal Text Designers: A Case Study Of Literacy Events In A Multicultural Context, Mary-Virginia Feger

USF Tampa Graduate Theses and Dissertations

The erasure of Latino/a adolescents' multiliteracies in school settings affects both their views of education and their entry into the community outside of school. Framed by literacy-as-social-practices perspectives and communities of practice theory, this case study explored what happened when a group of 13 Latino/a adolescents and their Latina teacher engaged in a six-week play production in an after-school program and performed the play for parents. It examined the relationship between the participants' discourse practices and their performance, and determined how they validated their performances. Data collected included observations, interviews, students' written reflective responses, a fieldwork journal, and a DVD …

Shell Abnormalities In Archaias Angulatus (Foraminifera) From The Florida Keys: An Indication Of Increasing Environmental Stress?, Heidi Lynne Souder

USF Tampa Graduate Theses and Dissertations

Historically, Archaias angulatus has been a major contributor to foraminiferal assemblages and sediments in coral-reef environments throughout the Caribbean and tropical Atlantic. A variety of anomalous features were observed in the tests of A. angulatus individuals collected live from the Florida reef tract in 2004 and 2005. Six types of anomalies were documented using scanning electron microscopy: microborings, microbial biofilm, pitted surfaces, dissolution, calcification abnormalities, and growth abnormalities. Calcification abnormalities included mineralogical projections, lacy crusts, and repair marks. These abnormalities were found among both juvenile and adult A. angulatus, and similar features were also found among Cyclorbiculina compressa and …

Developing Feminist Activist Pedagogy: A Case Study Approach In The Women's Studies Department At The University Of South Florida, Stacy Tessier

USF Tampa Graduate Theses and Dissertations

In this thesis, I examine the relationship between activism and the two introductory-level Women's Studies classes, Introduction to Women's Studies and Issues in Feminism, and the social justice mission of the Women's Studies department. These two classes are the pillars for the program and are often the first classes that draw students into the program. I propose that the Women's Studies department does promote social justice through the curriculum and there are ways that the department could do more to facilitate activism in the classroom and beyond the classroom.

The Women's Studies department at the University of South Florida is …

Beyond Orthographic Segmentation: Neurophysiological Evidence That Pseudo-Derived Word Stems Are Processed Semantically, Theresa Herbert

USF Tampa Graduate Theses and Dissertations

Morphological segmentation while reading is essential for new vocabulary learning. The study's aim was to investigate semantic-level morphological segmentation using event-related brain potentials (ERPs) in typical young adult readers. Past research has suggested that, because semantically opaque words prime their stems (e.g., corner/corn) similarly to transparent words (e.g., farmer/farm), readers recognize complex words from their constituent morphemes without regard to semantic information. However, this priming effect may be due to orthographic and phonological overlap between prime and target words. The research presented here addressed this possibility by creating five conditions in which orthographic, phonological, and semantic relationships between …

Risk Communication: An Analysis Of Message Source And Function In Hurricane Mitigation/Preparedness Communication, Andrew M. Gallo

USF Tampa Graduate Theses and Dissertations

In September 2008, the National Weather Service (NWS) predicted that Hurricane Ike would make landfall on Galveston Island as a strong category three storm. This led the NWS to release a statement of 'certain death' if people did not adhere to the emergency evacuation messages. Millions of people fled the Texas coast. Using Hazleton and Long's (1993) taxonomy of public relations strategies, experimental methods were conducted with various evacuation messages to test emergency communication. Grunig's (1997) situational theory of publics was used to determine strategy influence. Problem recognition, constraint recognition, and level of involvement were tested. In addition, tests were …

A Multiple Case Study Analysis Of Middle Grades Social Studies Teachers' Instructional Use Of Digital Technology With Academically Talented Students At Three High-Performing Middle Schools, Caroline C. Sheffield

USF Tampa Graduate Theses and Dissertations

Appropriate education for academically talented students incorporates the use of complex thinking skills, and encourages the development of interpersonal and leadership skills. One potential tool to achieve these goals is the use of instructional technology. Siegle (2004a, 2005) suggests that it is particularly appropriate to utilize technology with the highly-able because they often possess skills that are effective when using today's technology, specifically abstract thinking and rapid processing.

This mixed methods multiple case study explored middle school social studies teachers' instructional use of digital technology to teach highly-able students. The participant teachers were from three high-performing schools, as identified by …

The Health Professions Education: A Bridge to Quality (IOM, 2003) proposed strategies for higher education leaders and faculty to transform their institutions in ways that address the healthcare problems. This study provides higher education leaders and faculty with empirical data about the processes of change involved to implement the core competency of healthcare informatics. I chose the core competency of health care informatics as a base from which to conduct semi-structured interviews with faculty and college leaders at three schools of nursing intending to capture their stories about how healthcare informatics has been implemented, what strategies were used, and why …

How Personality And Self-Identity Impact The Effects Of Leader Member Exchange On Role Stressors And Organizational Outcomes, Edward Rickamer Hoover

USF Tampa Graduate Theses and Dissertations

This study investigated how followers' personality and self-identity moderated their leader's ability to influence organizational outcomes through management of role stressors experienced by the follower. Data was obtained through large group testing, sample size equaled 232, with performance measures being provided by supervisors (43% return rate). Results demonstrated that while Leader Member Exchange (LMX) had a linear relationship with role ambiguity and role conflict, it had a curvilinear relationship with role overload. Thus providing evidence that under certain conditions leadership can lead to negative outcomes. Furthermore, it was demonstrated that LMX indirectly influences both affective and cognitive variables through role …

Beyond Academic Reputation: Factors That Influence The College Of First Choice For High Achieving Students, Holly J. Schoenherr

USF Tampa Graduate Theses and Dissertations

Studies that have investigated college choice factors for high-achieving students repeatedly cite academic reputation as one of the top indicators of choice but have not indicated why some high-achieving students choose to attend universities with a less prestigious reputation than the more highly prestigious options available to them. The purpose of this study was to examine whether differences exist between traditional-aged high achieving students who choose to attend higher-tiered universities and their peers who choose to attend lower-tiered universities.

Independent variables were selected based upon Hossler and Gallagher's (1987) three-stage model and previous research findings in the literature and grouped …

Influence Of Temporary Inactivation Of The Prefrontal Cortex Or Hippocampus During Stress On The Subsequent Expression Of Anxiety And Memory, Joshua D. Halonen

USF Tampa Graduate Theses and Dissertations

The neural pathways underlying the symptoms of Post Traumatic Stress Disorder (PTSD) have not been fully elucidated. Intrusive memories, persistent anxiety and other cognitive deficits have been attributed to maladaptive or otherwise aberrant processing in specific brain regions, including the hippocampus, amygdala and prefrontal cortex. Our laboratory has developed an animal model of PTSD which results in the enhancement of memory for a place associated with exposure to a predator, anxiety-like behavior, increased startle and impaired memory in a non-aversive memory task. To better understand how the interaction of the hippocampus and prefrontal cortex contribute to the different symptoms of …

Gender Trouble In Northern Ireland: An Examination Of Gender And Bodies Within The 1970s And 1980s Provisional Irish Republican Army In Northern Ireland, Jennifer Earles

USF Tampa Graduate Theses and Dissertations

With this thesis, I will utilize both feminist and queer theory to highlight the gendered and bodily tactics used by the women of the 1970s/1980s Provisional Irish Republican Army. I will explore how women can both manipulate gender and use their bodies as a response to gender, ethnic, class, and colonial power relations and conflict discourses, the limitations of these approaches, and how these actions can work to reconfigure political movements, local cultures, and create a space for social change and a future beyond conflict which includes women. My methods will include a feminist content analysis of interviews, written records, …

Modulation Of Asic1a Function By Sigma-1 Receptors: Physiological And Pathophysiological Implications, Yelenis Herrera

USF Tampa Graduate Theses and Dissertations

Acid-sensing ion channels (ASIC) are a class of ligand gated plasma membrane ion channels that are activated by low extracellular pH. During ischemia, ASIC1a are activated and contribute to the demise of neurons. Pharmacological block of ASIC1a provides neuroprotection at delayed time points. However, no endogenous receptors have been implicated in the modulation of ASIC1a activity. The hypothesis presented is that sigma receptor activation inhibits ASIC1a function and ASIC1a-induced [Ca²?]i elevations during acidosis and ischemia, which may be a mechanism by which sigma ligands provide neuroprotection following stroke. This hypothesis is based on the following observations: First, sigma receptors regulate …

End-To-End Available Bandwidth Estimation And Monitoring, Cesar Dario Guerrero Santander

USF Tampa Graduate Theses and Dissertations

Available Bandwidth Estimation Techniques and Tools (ABETTs) have recently been envisioned as a supporting mechanism in areas such as compliance of service level agreements, network management, traffic engineering and real-time resource provisioning, flow and congestion control, construction of overlay networks, fast detection of failures and network attacks, and admission control. However, it is unknown whether current ABETTs can run efficiently in any type of network, under different network conditions, and whether they can provide accurate available bandwidth estimates at the timescales needed by these applications.

This dissertation investigates techniques and tools able to provide accurate, low overhead, reliable, and fast …

The Daily Show: Journalism’S Jester, Mark R. Mccarthy

USF Tampa Graduate Theses and Dissertations

The social meaning of television news has been under transformation since the successes of cable news in the final years of the previous century. In their attempts to preserve viewership and to remain relevant, traditional broadcast news outlets increasingly emulate the conventions of cable news. Instead of retaining audiences, the result has been declining news content and a continued loss of viewers. Amid these industry transformations, the concept of “journalist” continues to undergo change. This evolution of the news allows for a decidedly unique response to news programming in The Daily Show With Jon Stewart. Though advertised as a half-hour …

The Modern Community Garden Movement In The United States: Its Roots, Its Current Condition And Its Prospects For The Future, Joshua Birky

USF Tampa Graduate Theses and Dissertations

Numerous researchers have shown that community gardens have the potential to eliminate social, communal, health, agricultural and economic problems that many in the United States and the rest of the world are facing. Yet, throughout history allotment and community gardens have been seen as improper elements of urban landscapes and used predominately for crisis mitigation and not as sustainable solutions. This thesis shows that the current U.S. community garden movement is inherently different than past unsustainable movements and may establish community gardens as sustainable features of many municipalities in the U.S. This is because the modern U.S. movement is supported …

Program Monitoring In A Mandatory-Results Model, Srikar Reddy Reddy

USF Tampa Graduate Theses and Dissertations

In many real enforcement systems, a security-relevant action must return a result before the application program that invoked that action can continue to execute. However, current models of runtime mechanisms do not capture this requirement on results being returned to application programs; current models are limited to reasoning about policies and enforcement in terms of actions alone, without considering the results of those actions. This thesis presents a more general model of runtime policy enforcement in which all actions return (possibly void- or unit-type) results. This mandatory-results model more accurately reflects the capabilities and limitations of real enforcement mechanisms, particularly …

Loyalty Of Online Faculty: A Work Design Perspective Of The Impact Of A Telecommuting Work Environment On Employee Loyalty, Kenneth N. Pereira

USF Tampa Graduate Theses and Dissertations

ABSTRACT This study empirically evaluates the theoretical impact of a telecommuting or online work environment on employee loyalty. While the concept of employee loyalty has been extensively researched, the concept of the impact of the work environment on employee loyalty is fairly new. Specifically, this study operationally defines the work environment characteristics that contribute to employee loyalty and examines the impact of the online or telecommuting work environment on employee loyalty. A survey instrument is utilized to collect perceptual data about the psychological components of the work environment and their impact on employee loyalty from the employee's perspective. Multiple linear …

The Influence Of Parental Support On Antisocial Behavior Among Sixth Through Eleventh Graders, José Ordóñez

USF Tampa Graduate Theses and Dissertations

The primary objective of this study was to explore the influence of parental support on antisocial behavior among 1514 adolescents from Sarasota County (Florida). An integrated multilevel approach was developed considering elements of the social support paradigm and social learning theory. Using Hierarchical Linear Modeling (HLM), the results suggest that both paternal and maternal support were significant factors in the prevention of antisocial behavior. However, paternal support demonstrated to be stronger when students justified school misbehavior. At the school level, the findings suggest that the influence of parental support to reduce antisocial behavior competes with favorable definitions toward crime learned …

A Framework For Resource Assignments In Skill-Based Environments, Luis Daniel Otero

USF Tampa Graduate Theses and Dissertations

The development of effective personnel assignment methodologies has been the focus of research to academicians and practitioners for many years. The common theory among researchers is that improvements to the effectiveness of personnel assignment decisions are directly associated with favorable outcomes to organizations. Today, companies continue to struggle to develop high quality products in a timely fashion. This elevates the necessity to further explore and improve the decision-making science of personnel assignments. The central goal of this research is to develop a novel framework for human resource assignments in skill-based environments. An extensive literature review resulted in the identification of …

A Quasi Yagi Antenna With End Fired Radiation Over A Metal Ground, Sergio E. Melais

USF Tampa Graduate Theses and Dissertations

This dissertation presents a detailed investigation on the development of a quasi Yagi antenna with end fire radiation at 2.4 GHz (ISM band) over a metal reflector. Realization of an end fire radiator on top of a metal ground is very difficult because the reflected waves and image currents from the ground degrade the frequency bandwidth and steer the radiation pattern in the broadside direction. This destructive interference is reduced in this research through two quasi Yagi-ground configurations. The first arrangement utilizes a substrate of suitable thickness (7.5mm-0.19 ?g) to displace the ground away from the antenna. The second design …

Behavioral Skills Training With Teachers: Maintenance And Booster Training, Israel B. Miller

USF Tampa Graduate Theses and Dissertations

Behavioral skills training (BST) has been employed within many different populations to effect change in the way of reduction or acquisition of behaviors. For this study, a multiple-baseline across participants and modified ABAB design were employed. Analogue assessments and in-situ probes were conducted with three teachers following an initial training which occurred several months previously. These pre-assessments were followed by a separate booster training session for each individual teacher which lasted three and a half hours or less. Following the training, analogue and in-situ post assessments were conducted with each teacher. The independent variable was the booster training and the …
