The Effects Of Labyrinthula Sp. Infection, Salinity, And Light On The Production Of Phenolic Compounds In Thalassia Testudinum, Jennifer M. Sneed

USF Tampa Graduate Theses and Dissertations

In the fall of 1987, several areas of Florida Bay were severely affected by the sudden die-off of the seagrass Thalassia testudinum Banks ex Konig (turtle grass). Although the cause is still unknown, several factors were suggested as influencing the on-set of the die-off event including increased salinity, light stress due to self-shading, and disease. Blades of seagrass plants found in the area of die-off were infected by Labyrinthula sp, a pathogenic protist. A similar die-off occurred in another species of seagrass, Zostera marina, in the 1930s that was attributed to the pathogenic protist, Labyrinthula zosterae. Zostera …

Reconstructing Writer Identities, Student Identities, Teacher Identities, And Gender Identities: Chinese Graduate Students In America, Peiling Zhao

USF Tampa Graduate Theses and Dissertations

The increasing presence of Chinese international graduate students in American higher education has mandated a closer examination of their multifaceted lives against stereotypes that hinder their efforts to find, transform, or assert their identities in the dominant discourses of American academia and culture.

Cross cultural studies of Chinese international students tend to reinforce stereotypes of their writer identities, learner identities, and teacher identities. Examining these various identities discloses dichotomies that read Chinese students’ traits and behaviors as handicaps and thus characterize them as “abnormal” in relation to the “normal” traits and behaviors of Chinese students’ Western counterparts. Whereas Western student …

One More River To Cross: The Therapeutic Rhetoric Of Race In The Post-Civil Rights Era, Nigel I. Malcolm

USF Tampa Graduate Theses and Dissertations

The rhetoric of W.E.B. Du Bois contributed both to a sense of group failure among blacks and a sense of individual failure. Du Bois also created a need to explain the reasons for the failure of the group, as well as that of individuals within the group, specifically those within a segment of the black population deemed the talented tenth. Today the talented tenth is more generally spoken of as those occupying positions within the black middle class. Explanations for failure among blacks as a group are generally of two kinds. The first posits that the failure blacks experience as …

A Fuzzy Logic Based Controller To Provide End-To-End Congestion Control For Streaming Media Applications, Bay Pavlick

USF Tampa Graduate Theses and Dissertations

The stability of the Internet is at risk if the amount of voice and video traffic continues to increase at the current pace. While current transport layer protocols do work well for most applications, they still present some problems. TCP is reliable, tracks the state of some network conditions and reacts drastically to an indication of congestion. TCP serves data-oriented applications very well but it can lead to unacceptably low quality for streaming applications by multiplicatively reducing the congestion window upon a sign of congestion. The other main transport layer protocol, UDP, provides good service for streaming applications but is …

Perceived Competency In Female Primary Caregivers Of Infants And Toddlers With Medical And/Or Developmental Disabilities, Berney J. Wilkinson

Effects Of Adoptive Transfer Of Beta-Amyloid Sensitive Immune Cells In A Mouse Model For Alzheimer’S Disease, Daniel Shippy

USF Tampa Graduate Theses and Dissertations

One major therapeutic target for preventing and treating Alzheimer's Disease (AD) is removal of excess β-amyloid (Aβ) from the brain. Both active and passive immunotherapies targeting Aβ have proven effective in reducing brain Aβ levels and improving cognitive function in mouse transgenic models of AD. However, these approaches can induce adverse neuropathologic effects and immunologic over-activation. Indeed, clinical trials of active Aβ immunotherapy in AD patients were halted due to development of meningoencephalitis, apparently resulting from wide-spread neuroinflammation. Here we show that a more restricted and specific immune re-activation through a single adoptive transfer of Aβ-specific T cells can provide …

Performance Optimization In Three-Dimensional Programmable Logic Arrays (Plas), Supriya Sunki

USF Tampa Graduate Theses and Dissertations

Increased chip size and reduced feature size has helped following Moores law for long decades. This has an impact on interconnect length, which is resulting in chip performance degradation. Despite the introduction of new materials with Low-K dielectrics for interconnects, their delay is expected to substantially limit the chip performance. To overcome this problem the need for new technology has arrived. One such promising technology is the three-dimensional Integrated chips (3D ICs) with multiple silicon layers.

Measuring Transactional Distance In Online Courses: The Structure Component, Cheryl Sandoe

USF Tampa Graduate Theses and Dissertations

Online or web-based courses have become prolific in our educational environment over the past several years. The development of these courses can be guided by systematic design models to ensure quality instructional design. Transactional distance, the theory that claims the distance an online student feels is more of a pedagogical distance than a geographic one, consists of three factors: structure, dialogue, and learner autonomy. Accurate measurement of these three factors is needed in order to substantiate its claims and to best determine the delivery implications. This study produced an instrument that measures the structure component of the transactional distance theory …

The current study explored the relationship between parents perceptions of their childs middle school and parents perceptions of their own school experiences. Additionally, it was important to research how these relationships differed among variables. The variables explored were (1) race, (2) parents own educational backgrounds (level of education), and (3) socio-economic status. Based on scales commonly used in the study of parent involvement, a survey (i.e., Parent Perceptions of Schooling) was developed. The survey consisted of two parts (i.e., Part I, How I Feel About My Childs School and Part II: Parents Own School Experiences Questionnaire) and a demographic section …

Gender And Generational Differences In The Self-Ratings Of Leadership Practices By Elementary School Administrators Within Four Florida Counties, Michele E. Polk

USF Tampa Graduate Theses and Dissertations

Considerable research has been conducted over time on possible gender differences, with varying results regarding the existence and/or degree of differences. In particular, research on differences in leadership practices of men and women have abounded since the 1970s as women began to make their way into management and supervisory positions.

In todays work force, several generations can be found working together within a single work setting. Possibly, differences in leadership may be more generational than gender related; however, little research has considered both gender and generation as variables. This study adds to literature relating to the existence of gender and/or …

Establishing A Farmers Market For A Low-Income Latino Community, Ann L. Bretnall

USF Tampa Graduate Theses and Dissertations

For the past decade, Florida’s Latino population has significantly increased and is now the third largest in the United States. The same trend has also occurred in Hillsborough County. Social and economic disparities are significant as Latinos earn less than non-Hispanic whites and many live in poverty. A major concern of this population is the lack of access to inexpensive fresh fruits and vegetables. Findings from prior research show that the diet of immigrants often change quickly upon their arrival to the United States, with an increased emphasis on fast food and soft drinks and a reduction in the consumption …

Postmodern Narrativity In Absalom, Absalom! And Memento: Examining Telling Similarities In The Techniques Of William Faulkner And Christopher Nolan, Jessica Jain Williams

USF Tampa Graduate Theses and Dissertations

This paper argues that narrative techniques in Absalom, Absalom! demonstrate Faulkners anticipation of postmodern thought and style. Similar techniques in Christopher Nolans film Memento serve to highlight how both writer and director confound the notion of master narrative by disrupting chronology and raising questions about the reliability of the narrators in each work. Nolan orders all events of the film in reverse while threading chronologically ordered events throughout to tell the story of Lennys murder investigation. Faulkner likewise uses "dischronology," such as flashbacks to tell the story of Thomas Sutpen. Both Faulkner and Nolan provide key information through questionable narrators …

Exhaled Breath Nitric Oxide: Is There A Baseline Difference Due To Ethnicity?, Sunita I. Patel M.D.

The air that humans exhale contains various chemical markers whose levels have been associated with various respiratory disorders. Therefore, measurement of these markers offers a potential method of examining airway disease status. Furthermore, exhaled breath offers the advantage of being easy to collect and non-invasive. Hence, these exhaled breath markers are potentially of significant clinical use in examining airways. Therefore, examination of exhaled breath has become the subject of intense study. Current research is targeting the development of methods and parameters for looking at these markers.

The goal of this cross-sectional pilot study was to consider the variability in the …

Professional Wrestling, Embodied Morality, And Altered States Of Consciousness, Lawrence B. Mcbride

USF Tampa Graduate Theses and Dissertations

Much of the scholarly work on professional wrestling is based on the assumption that beyond a simple mimicking of sporting combat, the wrestling show is a spectacle that constructs and interrelates socially situated, morally significant categories. In this thesis, I focus on wrestlers themselves, and treat wrestling as a traditional practice that guides how wrestlers relate to their bodies and how they interact with their audience. This project was carried out using ethnographic methods of observation and interviewing. While participant-observation of three independent wrestling promotions provided context, twelve semi-structured interviews carried out with wrestlers at the Florida Wrestleplex in St. …

Effect Of Age On 11- To 18-Year-Olds’ Discrimination Of Nuances In Instrumental And Speech Phrase Interpretations, Andrew Sioberg

USF Tampa Graduate Theses and Dissertations

This dissertation was a continuation of study on a theory of a learning window for the perception of expressive qualities in music and speech. The proposed theory suggested that a practice window must overlap a learning window before it closes around the age of 10. This dissertation sought to determine whether children older than the proposed learning window continued to improve in speech and musical discrimination skill, or leveled off in this ability. It also examined the impact of gender and private lesson experience on discrimination ability.

Instrumental music students (n = 292) attending a public magnet school for visual …
