Bacteriophage For The Elimination Of Methicillin-Resistant Staphylococcus Aureus (Mrsa) Colonization And Infection, Angela Clem
USF Tampa Graduate Theses and Dissertations
Methicillin-resistant Staphylococcus aureus (MRSA) is among the most important pathogens affecting the human race in our time. In spite of recent medical advances, our therapeutic choices for MRSA infections remain limited due to the propensity of this organism to develop resistance to antimicrobials. Therefore, there is a continuing need to develop newer methods of treating MRSA infections. This dissertation examines the effects of bacteriophages 88 and 92 on ten clinical isolates of MRSA from the central Florida area. . For the majority of the MRSA isolates, bacteriophages 88 and 92 were unable to induce lysis. However, bacteriophage 88 was found …

Reconstructing 20th Century Sst Variability In The Southwest Pacific: A Replication Study Using Multiple Coral Sr/Ca Records From New Caledonia, Kristine L. Delong
USF Tampa Graduate Theses and Dissertations
Coral-based climate reconstructions typically have not used multiple cores from a region to capture and replicate a climate signal largely because of concerns focused on coral conservation, analytical expense, and time constraints. Coral Sr/Ca reproducibility through the 20th century was investigated using three intra-colony and three inter-colony coral records, from the reefs offshore of Amédée Island, New Caledonia. Different sampling resolutions were examined in coral Sr/Ca (fortnightly and monthly) and delta 18O (fortnightly, monthly, and seasonally) as well as similar scale subsampling of the daily in situ SST record. The mean coral Sr/Ca, delta 18O, and daily SST values do …
The Commodification Of Yoga In Contemporary U.S. Culture, Michelle E. Demeter
The Commodification Of Yoga In Contemporary U.S. Culture, Michelle E. Demeter
USF Tampa Graduate Theses and Dissertations
Yoga is an increasingly visible and versatile commodity in the United States health market. Though its origins stretch to pre-Vedic India and its traditional religious purpose is linked to Hinduism, it is evident that yoga has undergone much change since its transmission to U.S. culture. In its popular, widespread incarnation in the United States, yoga is not usually learned at the feet of a guru, but at exercise centers and gyms. These secular locales of yoga's practice help define the "yoga phenomenon" in contemporary America. This phenomenon has resulted in yoga's wide acceptance and high visibility in American popular culture …

Using Emergent Outcome Controls To Manage Dynamic Software Development, Michael Loyd Harris
Using Emergent Outcome Controls To Manage Dynamic Software Development, Michael Loyd Harris
USF Tampa Graduate Theses and Dissertations
Control and flexibility may appear an unlikely pair. However, I propose that effective management of dynamic environments, such as systems development under conditions of uncertainty, must still provide clear control mechanisms to manage the progress and quality of the resulting products. This dissertation presents research to understand the types of control used in the context of flexible software development processes. The dynamic capabilities extension to the resource-based view of the firm is used to understand dynamic environments. Within those environments, control theory is used to understand how activities are guided and controlled to achieve management objectives. Specifically, control theory acts …

The Relationship Between Nurses' Anxiety And Attitude Related To Pediatric Hospice, Teresa Lyn Hoover
The Relationship Between Nurses' Anxiety And Attitude Related To Pediatric Hospice, Teresa Lyn Hoover
USF Tampa Graduate Theses and Dissertations
To lose a child is a profoundly emotional experience. Even if it is not your own, the experience involves deeply held beliefs about death, the quality of death, ethics, and perhaps personal experience. Left unexplored, these beliefs and the anxiety they may produce, can become barriers to providing quality end-of-life care for children with life limiting conditions and their families. The purpose of this study was to explore the relationship between hospice nurses' attitudes toward providing pediatric hospice care and the level of anxiety they may experience related to pediatric hospice care. A self administered questionnaire was completed by 30 …
Cranial Biomechanics And Feeding Performance Of Sharks, Daniel Robert Huber
Cranial Biomechanics And Feeding Performance Of Sharks, Daniel Robert Huber
USF Tampa Graduate Theses and Dissertations
The elasmobranch fishes possess a remarkable diversity of feeding mechanisms for a group containing relatively few species (~1200). The three most prevalent of these mechanisms involve prey capture during which the predator overtakes its prey (ram), prey is drawn into the mouth of the predator (suction), and relatively stationary consumption of sessile or substrate affixed prey (biting). Biomechanical modeling of cranial force distributions, in situ bite performance trials, and kinematic analysis of prey capture behaviors were employed to identify morphological and behavioral specializations and constraints associated with these feeding mechanisms in lemon Negaprion brevirostris (ram), whitespotted bamboo Chiloscyllium plagiosum (suction), …
Are Respiratory Behaviors Affected In Individuals With Adductor Spasmodic Dysphonia?, Katie Biedess
Are Respiratory Behaviors Affected In Individuals With Adductor Spasmodic Dysphonia?, Katie Biedess
USF Tampa Graduate Theses and Dissertations
Adductor spasmodic dysphonia (ADSD) is a focal dystonia that is characterized by voice breaks due to involuntary contractions of the adductor muscles of the vocal folds. These spasms can interfere with the coordination and balance of the respiratory and phonatory systems interfering with normal voice production. Disruptions in normal respiratory behaviors are well documented in inviduals with laryngeal disorders, including ADSD. Previous research regarding respiratory processes in ADSD has focused on airflow and pressure; however, there are many other parameters that have not been considered and may shed new light on the respiratory behaviors of individuals with ADSD. Therefore, the …
Mathematical Model Of Arsenic Adsorption In A Modified Zeolite / Microfiltration System, Miles B. Beamguard
Mathematical Model Of Arsenic Adsorption In A Modified Zeolite / Microfiltration System, Miles B. Beamguard
USF Tampa Graduate Theses and Dissertations
Carcinogenic health concerns over arsenic in drinking water caused the USEPA to reduce the maximum contaminant level (MCL) from 50 to 10 ppb, effective on January 23, 2006. This has forced many smaller utilities into expensive treatment or discontinuation of water distribution. Researchers throughout the world are working to develop an inexpensive method for arsenic removal to meet this MCL. Aluminum silicates, or zeolites, are naturally occurring ionic sorbents. Modification of a zeolite may enhance adsorption capacities and ion selectivity. This research investigates the arsenic adsorption capacities of a modified Chabazite. This adsorption, coupled with a hollow fiber, microfiltration membrane …
Arts In New Directions The Development And Application Of A Construct That Uses The Arts To Promote Transformation And Self-Actualization In Health Care And Education/Therapy, Alexxis Avalon
USF Tampa Graduate Theses and Dissertations
Artistic methods to evoke relaxation, spark creativity, and change self-perceptions are already being used by therapists, educators, and scientists. Interdisciplinary collaborations among researchers are developing to create new paradigms that incorporate the use of arts to empower individuals. By describing various connections between the arts and participants, researchers are looking at the expressive arts (including dance, music, drama, poetry, and visual arts) for transformation and self-actualization.The problem is that no construct is available to describe the transformation, "the conscious move from one deep structure of knowledge to another" (Wilber, 2004), that occurs when using the arts in health care and …

Adolescent Alcohol Use And Educational Outcomes, Wesley A. Austin
Adolescent Alcohol Use And Educational Outcomes, Wesley A. Austin
USF Tampa Graduate Theses and Dissertations
There is some controversy over whether adolescent alcohol use has deleterious causal effects on educational outcomes. In particular, does drinking reduce academic performance and school enrollment rates and increase truancy, or does the observed negative correlation between drinking and educational outcomes merely reflect common unobservable factors? This dissertation sheds further light on the issue by estimating the causal impacts of alcohol use on various educational outcomes. Specifically, an instrumental variables model is estimated to study the effects of several drinking measures on grades, school enrollment and absenteeism.

A Case Study Of A School Implementing A Constructivist Philosophy, Joseph C. Brown
A Case Study Of A School Implementing A Constructivist Philosophy, Joseph C. Brown
USF Tampa Graduate Theses and Dissertations
Isaacson's (2004) dissertation chronicles the implementation of a constructivist instructional approach at Southwood Elementary School. Southwood's faculty experienced a change of principals, which the Tri-Partite Theory of Organizational Change and Succession, a theory of organizational entropy, predicts could lead to organizational entropy. This study examines the dynamics of the change in principal, as well as Isaacson's recommendation to study teachers' perceptions regarding the maintenance of the constructivist approach. This study answers three questions: 1) Are faculty still using constructivist strategies? 2) What are teacher perceptions regarding the maintenance and support of constructivist philosophy? 3) Is there congruence between what literature …

Cloning And Analysis Of Putative Collagenases Of The U32 Family In Streptococcus Mutans And Streptococcus Agalactiae (Group B Streptococci), Valerie Carson
USF Tampa Graduate Theses and Dissertations
Analysis of the genomic sequences of Streptococcus mutans UA159 and Group B Streptococcus (GBS) strains Streptococcus agalactiae NEM316 and S. agalactiae 2603V/R indicated the presence of two putative collagenase genes in each organism. smcol1 from S. mutans was previously cloned and analyzed and the results indicated that the enzyme belonged to the U32 family of collagenases/peptidases. This enzyme shares homology with the prtC of Porphyromonas gingivalis, one of the principal examples of the U32 family of peptidases. Considering the potential role of these enzymes in the pathogenicity of P. gingivalis (periodontitis or gum disease), GBS (premature rupture of the amniochorionic …
Folk Wiki: The Shared Traditions Of Folk Music And The Wiki Way, Phillip Mark Chamberlin
Folk Wiki: The Shared Traditions Of Folk Music And The Wiki Way, Phillip Mark Chamberlin
USF Tampa Graduate Theses and Dissertations
Wiki is often perceived as representing a revolutionary break from conventional notions of authorship, writing, and textual history. Dialogues concerning Wiki tend to ignore the characteristics that Wiki shares with earlier forms of collaboration, particularly folk music. In both Wiki and folk music, content is often collectively shared and authored, even if specific individuals create and change the content. Many collaborators are anonymous, quasi-anonymous, or pseudo-anonymous, but the perception of this anonymity is, in both genres, problematic. Second, both Wiki documents and folk songs exist in the "Eternal Now," a seemingly perpetual state that makes these texts available for addition, …

Monitoring Water Quality In Tampa Bay: Coupling In Situ And Remote Sensing, Zhiqiang Chen
Monitoring Water Quality In Tampa Bay: Coupling In Situ And Remote Sensing, Zhiqiang Chen
USF Tampa Graduate Theses and Dissertations
Water quality in Tampa Bay was examined using concurrent in situ and satellite remote sensing observations. Chlorophyll and suspended sediment concentrations showed large short-term variability, primarily driven by tide and wind forcing. Superimposed on these high frequency variations were recurrent phytoplankton blooms stimulated by decreases in turbidity 1-2 days after wind-induced bottom sediment resuspension events; the blooms were particularly strong if neap tides occurred after the wind events. The in situ data show that observations once per month are inadequate to sample short-term variability and that therefore the current monthly water quality surveys may have uncertainties of -50 to 200% …

This study was an examination of timbre discrimination and labeling, with specific consideration of the soprano-brass timbres of cornets and trumpets. This study sought to determine whether instrumentalists differed in their ability to label and discriminate cornet and trumpet timbres, and whether these abilities were influenced by the instrumentalists' performing instrument and years of playing experience. Wind, brass and percussion players (n=100) from existing instrumental groups in the Tampa Bay area participated in the study. These groups were collegiate trumpet majors from a large public university school of music, a collegiate wind ensemble from a private university, and a brass …
Behavioral And Auditory Evoked Potential (Aep) Hearing Measurements In Odontocete Cetaceans, Mandy Lee Hill Cook
Behavioral And Auditory Evoked Potential (Aep) Hearing Measurements In Odontocete Cetaceans, Mandy Lee Hill Cook
USF Tampa Graduate Theses and Dissertations
Bottlenose dolphins (Tursiops truncatus) and other odontocete cetaceans rely on sound for communication, navigation, and foraging. Therefore, hearing is one of their primary sensory modalities. Both natural and anthropogenic noise in the marine environment could mask the ability of free-ranging dolphins to detect sounds, and chronic noise exposure could cause permanent hearing losses. In addition, several mass strandings of odontocete cetaceans, especially beaked whales, have been correlated with military exercises involving mid-frequency sonar, highlighting unknowns regarding hearing sensitivity in these animals.Auditory evoked potential (AEP) methods are attractive over traditional behavioral methods for measuring the hearing of marine mammals because they …
