Robots Without Faces: Non-Verbal Social Human-Robot Interaction, Cindy L. Bethel

USF Tampa Graduate Theses and Dissertations

Non-facial and non-verbal methods of affective expression are essential for naturalistic social interaction in robots that are designed to be functional and lack expressive faces (appearance-constrained)such as those used in search and rescue, law enforcement, and military applications. This research identifies five main methods of non-facial and non-verbal affective expression (body movement, posture, orientation, color, and sound). From the psychology, computer science, and robotics literature a set of prescriptive recommendations was distilled for the appropriate non-facial and non-verbal affective expression methods for each of three proximity zones of interest(intimate: contact - 0.46 m, personal: 0.46 - 1.22 m, and social: …

Evaluating The Effects Of Exergaming On Physical Activity Among Inactive Children In A Physical Education Classroom, Victoria A. Fogel

USF Tampa Graduate Theses and Dissertations

Childhood obesity is a serious concern that requires the attention of the behavioral community. The U.S. Department of Health and Human Services (2007) recommends that children engage in physical activity for 60 minutes per day. Children spend the majority of their day in school, making school an ideal environment to increase the opportunity for physical activity. Simple, straightforward interventions that can be applied in the school setting, which take into consideration the environment and focus on maintenance by making the process of engaging in physical activity reinforcing, are greatly needed. Video games have been noted in the literature as a …

Green Local Governments In Florida: An Analysis Of Sustainability And Green Building Policies, Naimish S. Upadhyay

USF Tampa Graduate Theses and Dissertations

Sustainable development is increasingly being integrated within local government planning across United States. Many communities are attempting to translate this general principle into specific and measurable terms. The urban sustainability planning literature has mostly focused on descriptive case studies of pioneering cities that have been characterized as true innovators in their sustainability efforts. Noticeably absent from the literature, however, has been an examination of the sustainable development claims made by local governments undergoing 'green' certifications. This study evaluates the commitment and efforts of municipalities and counties of Florida within the framework of Florida Green Building Coalition's 'Green …

The Neuron-Silicon Carbide Interface: Biocompatibility Study And Bmi Device Development, Christopher L. Frewin

USF Tampa Graduate Theses and Dissertations

Damage to the central nervous system (CNS) leads to the generation of an immune response which culminates with the encapsulation of the damaged area. The encapsulation, known as a glial scar, essentially breaks neural signal pathways and blocks signal transmissions to and from the CNS. The effect is the loss of motor and sensory control for the damaged individual. One method that has been used successfully to treat this problem is the use of a brain-machine interface (BMI) which can intercept signals from the brain and use these signals to control a machine. Although there are many types of BMI …

Structural Polarities In J.R.R. Tolkien's The Lord Of The Rings, Quincey Vierling Upshaw

USF Tampa Graduate Theses and Dissertations

My thesis reflects an assessment of The Lord of the Rings centering on the idea of a structure of opposites. For each place, race, character and object in The Lord of the Rings, J.R.R. Tolkien included an element which serves as an antithesis. In addition, the style, pacing, and language of the work also contain antithetical pairs which continually engage and propel the reader to the work's conclusion. I contend that this deliberate pairing of opposing elements adds depth and verisimilitude to the work.

Tolkien was an avid student of what his contemporaries would have called "fantasy" or "fairy …

Barriers And Facilitating Factors To High School Students’ School Engagement, Amy Green

USF Tampa Graduate Theses and Dissertations

Students who are engaged in their high school environment have higher graduation rates, fewer discipline problems, and lower delinquency rates. In addition, students who are connected to teachers and involved in extracurricular activities consistently experience positive outcomes. However, although the benefits of school resources such as extra-curricular activities and connections to supportive individuals during high school have been well documented, the factors influencing utilization of these resources have not yet been established. Given the known benefits of activity participation and connection to supportive individuals in school settings, and the voluntary nature of their utilization, it is important to investigate factors …

An Empirical Analysis Of Public Perception Of Reclaimed Water Applying The Situational Theory Of Publics, Jessica Voss

USF Tampa Graduate Theses and Dissertations

Utilizing J.E. Grunig's (1989a, 1997) situational theory of publics and Fishbein and Ajzen's (1975) theory of reasoned action, this empirical study examined the public's perception of reclaimed water. Specifically, the three independent variables - problem recognition, constraint recognition, and level of involvement - were separated into internal and external variables to determine their influences on behavioral intention. The independent variables were also used to determine the public's communication behavioral intention.

The findings of this study support the basic premise of the situational theory of publics and contribute to the extension of the theory through the inclusion of some of the …

An Empirical Examination Of The Dark Side Of Relationship Marketing Within A Business To Business Context, Brent L. Baker

USF Tampa Graduate Theses and Dissertations

A large number of empirical studies have illustrated the benefits of adopting and implementing a relational or relationship marketing strategy. However, there is an emergent stream of literature that suggests that despite the recognized benefits associated with this strategy there may also be a dark side that manifests itself between firms as a result of adopting a relationship marketing strategy. However, though this stream of literature recognizes the presence of the dark side, causal antecedents mediating the dark side constructs, or consequences of the dark side have yet to be theoretically derived, explained or empirically tested.

This dissertation constructs theoretical …

Blind Signal Detection And Identification Over The 2.4ghz Ism Band For Cognitive, Omar Zakaria

USF Tampa Graduate Theses and Dissertations

'It is not a lack of spectrum. It is an issue of efficient use of the available spectrum"--conclusions of the FCC Spectrum Policy Task Force.

There is growing interest towards providing broadband communication with high bit rates and throughput, especially in the ISM band, as it was an ignition of innovation triggered by the FCC to provide, to some extent, a regulation-free band that anyone can use. But with such freedom comes the risk of interference and more responsibility to avoid causing it. Therefore, the need for accurate interference detection and identification, along with good blind detection capabilities are inevitable. …

Examining An Acute Environmental Trigger For Dysfunctional Eating: Measuring The Immediate Impact Of Fat Disparagement Media Exposure And Its Effects On Body Dissatisfaction, Negative Affect, Weight Control Practice Intentions, And Sub-Clinical Binge Eating Behavior In College Women, Susan Himes

USF Tampa Graduate Theses and Dissertations

Binge eating is a maladaptive eating practice associated with unhealthy weight control methods (vomiting, laxative abuse) and the development of weight gain and obesity. Isolating psychological and environmental variables that trigger binge eating can prevent or potentially moderate eating disturbance. Previous research implicates media exposure as an environmental contributor to psychological and eating disturbance. The current study sought to uncover whether fat stigmatization media exposure is an acute environmental trigger for psychological disturbance and binge initiation by dismantling fat media messages and experimentally manipulating messages. Undergraduate women (N=197) were assigned to one of four media message conditions: a fat negative …

One Season In An Other’S: Examining Teacher Preparation In Cultural Relevance Literacy Through Intentional And Focused Teaching Case Use, Coleen E. Sams

USF Tampa Graduate Theses and Dissertations

Teacher educators need to develop better teaching methods in order to, ultimately, serve future students in classrooms that are increasing in diversity. It is vital that education majors do more than hear and read about social justice issues facing their prospective students; for them to both understand it and retain it, they need deeper interaction with the issues and alternative strategies for resolving them. This model for using teaching cases may enable teacher educators to demonstrate the relevance of their coursework to their midlevel education students, ultimately enhancing learning gains.

Of equal importance to their professional development, prospective teachers need …

Social shopping is one of the latest trends on the Internet. Websites dedicated to social networking with a focus on shopping have been emerging on the web for a few years. The basic idea is that consumers are looking for product information on the Internet and social shopping sites provide a place for consumers to find this information from other consumers. These sites provide a place for their users to engage in socialization and shopping simultaneously, sometimes following recommendations of premier users, who are labeled from other users. However, purchases aren't made through these sites. So, there may still be …

The Pessimism Of Horror Cinema: A Comparative Study Between Modernist And Postmodernist Horror Cinema, Michael Jeknavorian

USF Tampa Graduate Theses and Dissertations

This qualitative thesis examines levels of pessimism as they relate to modern and postmodern horror cinema. Beyond assumed differences in levels of pessimism between the two genres, the study also examines implicit and explicit moralization of these categories. Specifically, the study questions if postmodern horror cinema's characteristic increase in pessimism is simply a change in the genre's convention, yet a change that is irrespective of either genre's capabilities to moralize. First, the study singularly examines the conventions of each genre as it relates to levels of pessimism. Second, the study discusses works that bridge the two genres. And third, the …

A New Perspective On The Work-Family Interface: Linking Achievement Motivation And Work-Family Balance, Tiffany N. Smith

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to identify whether three achievement motivation variables (LGO, GNS, and AO) were positively related to work-family balance, and to investigate plausible interactions between these variables and work-family stressors on balance perceptions. Relationships of these variables to work-family conflict and facilitation outcomes were also analyzed in order to identify differential relationships. Data were collected from 428 individuals through a web-based survey. Results indicated that all three achievement motivation variables were clearly related favorably to work-family balance and facilitation, while only AO was negatively related to conflict. The relationships between schedule flexibility and all work-family outcomes …

Immunomodulatory Effects Of Novel Therapies For Stroke, Aaron A. Hall

USF Tampa Graduate Theses and Dissertations

Each year, approximately 795,000 people suffer a new or recurrent stroke. About 610,000 of these are first attacks, and 185,000 are recurrent attacks (Carandang et al. 2006). Currently the only FDA approved treatment for ischemic stroke is recombinant tissue plasminogen activator (Alteplase) (Marler and Goldstein 2003). Unfortunately its use is restricted to a short, 4.5 hour, time window. Two promising therapies in the treatment of stroke at delayed timepoints are human umbilical cord blood cells (HUCBC) and the sigma receptor agonist DTG

The first series of experiments were conducted to characterize the effects of sigma receptors on various aspects of …
