Gender Differences During Heat Strain At Critical Wbgt, Christina L. Luecke Jan 2006

Gender Differences During Heat Strain At Critical Wbgt, Christina L. Luecke

USF Tampa Graduate Theses and Dissertations

Heat stress is influenced by environmental conditions, workload and clothing. A critical environment is the upper limit of compensable heat stress for a given metabolic rate and clothing ensemble. The physiological strains associated with heat stress are core and skin temperatures, heart rate and physiological strain index (PSI). Because heat dissipation mechanisms may differ between men and women, there may be gender differences in the critical environment and the associated physiological variables. Gender differences were explored between acclimated men (n = 20) and women (n = 9) at the upper limit of compensable heat stress. Participants walked on a motorized …


Virginia Woolf And The Persistent Question Of Class: The Protean Nature Of Class And Self, Mary C. Madden Jan 2006

Virginia Woolf And The Persistent Question Of Class: The Protean Nature Of Class And Self, Mary C. Madden

USF Tampa Graduate Theses and Dissertations

From the beginning of her career, Virginia Woolf moves beyond the perspective of her inherited class position to challenge a damaging class system. She increasingly recognizes the extent of her own complicity in the creation and maintenance of class structures supporting patriarchy, war, and British imperialism. Highlighting ambiguities inherent in the very category of class, she acknowledges the limiting "boxes" of language itself in attempts to rethink class. For Woolf, class is not monolithic but internally differentiated by gender and race. Examining Woolf's early work in relation to class theory shows that throughout her career Woolf interrogates the imbrication of …


Investigation Of The Effects Of Increased Levels Of O-Glcnac Protein Modification On Protein Kinase C And Akt, Jason Aaron Matthews Jan 2006

Investigation Of The Effects Of Increased Levels Of O-Glcnac Protein Modification On Protein Kinase C And Akt, Jason Aaron Matthews

USF Tampa Graduate Theses and Dissertations

O-linked N-acetylglucosamine (O-GlcNAc) is an abundant and ubiquitous post-translational modification that has been shown to play a role in regulating a variety of intracellular processes. The pathway responsible for generating the O-GlcNAc modification, the hexosamine biosynthetic pathway (HBP), has also been shown to affect the activity and translocation of certain protein kinase C (PKC) isoforms. To investigate if the effects of HBP flux on PKC translocation observed by others is related to the O-GlcNAc modification, O-GlcNAc levels in human astroglial cells were elevated using four separate O-GlcNAc modulating agents followed by analysis of cytosol and membrane concentrations of PKC-epsilon, -alpha, …

Altered Features Of Female Pigeons (Columba Livia) Elicit Preference Behavior In Male Pigeons, Tadd B. Patton Jan 2006

Altered Features Of Female Pigeons (Columba Livia) Elicit Preference Behavior In Male Pigeons, Tadd B. Patton

USF Tampa Graduate Theses and Dissertations

Previous research has shown that male pigeons (Columba livia) respond with courtship displays to video playbacks of a female pigeon indicating that they 'recognize' the female as a potential mate. Courtship displays significantly decline when the head region of the female is occluded (Shimizu, 1998) suggesting that features located within the head are important for species recognition and mate selection. However, little is known about the exact visual features necessary to elicit displays. The current study examined the preference behavior of male pigeons when given a choice between photographic images of normal looking or altered female pigeon faces. The altered-face …


Clarifying The Cohesion-Performance Relationship In Teams: Backup Behavior As A Mediating Mechanism, Matthew S. Prewett Jan 2006

Clarifying The Cohesion-Performance Relationship In Teams: Backup Behavior As A Mediating Mechanism, Matthew S. Prewett

USF Tampa Graduate Theses and Dissertations

The relationship between team cohesion and team performance has been extensively studied, but behavioral mediators of this relationship have not been adequately assessed. This study proposed that backup behavior mediates the relationship between team cohesion and team performance. In addition, it was also hypothesized that team goal commitment would moderate the relationship between team cohesion and team backup behavior. 138 participants forming 46 teams of three were assigned to one of fours conditions to test this framework: high cohesion/high goal commitment, high cohesion/low goal commitment, low cohesion/high goal commitment, and low cohesion/low goal commitment. Results indicated no significant differences between …


Spin Polarization Measurements And Sensor Applications In Thin Films And Carbon Nanotube-Based Devices, Jeff T. Sanders Jan 2006

Spin Polarization Measurements And Sensor Applications In Thin Films And Carbon Nanotube-Based Devices, Jeff T. Sanders

USF Tampa Graduate Theses and Dissertations

The unique properties of carbon nanotubes (CNTs) show a great deal of potential for nanoelectronic devices, spintronic devices, biosensing and chemical sensing applications. Their applicability as interconnects for spintronic devices derives from their one-dimensionality and theoretically predicted preservation of spin current. In this work, we combine an investigation of spin polarization in materials such as half metallic oxides in thin film and bulk form with studies on several aspects of CNTs for sensing and spin transport applications. These two areas of study are intimately related within the umbrella of spin-electronics and nanoscale sensors that are being pursued with great topical …


The Causal Effect Of Alcohol Consumption On Employment Status, Chanvuth Sangchai Jan 2006

The Causal Effect Of Alcohol Consumption On Employment Status, Chanvuth Sangchai

USF Tampa Graduate Theses and Dissertations

Alcohol consumption may affect labor market outcomes directly through a reduction in productivity and indirectly through human capital accumulation. However, empirical results from previous studies in the economics literature are mixed and inconclusive. While some researchers found negative effects of alcohol use on labor market outcomes, quite a few studies found either positive or insignificant effects. The purpose of this dissertation is to estimate causal effects of alcohol consumption on employment status. It uses three data sets previously unexploited for this purpose and attempts to eliminate any potential estimation problems from previous studies. The results show that previous problematic heavy …


Advancements In Rapid Load Test Data Regression, Michael Jeffrey Stokes Jan 2006

Advancements In Rapid Load Test Data Regression, Michael Jeffrey Stokes

USF Tampa Graduate Theses and Dissertations

Rate-dependent effects introduced during rapid and/or dynamic events have typically been oversimplified to compensate for deficiencies in present analyses. As load test results are generally considered as the basis of performance from which foundations can be designed, it is imperative that the analyzed load test data be as accurate as possible. In an attempt to progress the state of load test data regression, this dissertation addresses two common assumptions made during the regression process: (1) the statnamic damping coefficient is constant throughout the entire load test and (2) the concrete stress-strain relationship is linear-elastic. Also presented is a case study …

“This Is Not A Politburo, But A Madhouse,” The Post World War Ii Sovietization Of East Germany Up To The 1953 Worker’S Uprising, Rush H. Taylor

USF Tampa Graduate Theses and Dissertations

The end of World War II brought forth many problems for the allies that had not been completely resolved by the victors. One of the most important was what to do with the defeated Germany. Within the first decade after World War II, the division of the former German superpower had become the front line of the Cold War between the United States and the Soviet Union. In the first eight years after the war (1945-53) East Germany, the Soviet controlled sector, quickly became 'Stalin's unwanted child' and was the first communist country to rebel against the imposed Soviet style …


Design And Synthesis Of Core Structural Intermediates For Novel Hiv-1 Protease Inhibitors & Synthesis, Biological Activity And Molecular Modeling Of Novel 20s Proteasome Inhibitors, Kiran Kumar Venkata Raja Avancha Jan 2006

Design And Synthesis Of Core Structural Intermediates For Novel Hiv-1 Protease Inhibitors & Synthesis, Biological Activity And Molecular Modeling Of Novel 20s Proteasome Inhibitors, Kiran Kumar Venkata Raja Avancha

USF Tampa Graduate Theses and Dissertations

HIV-1 protease binds to its peptide/protein substrates in extended conformations. Therefore protease inhibitors that are constrained to form extended conformations are likely to produce very active protease inhibitors. This is because they are pre-organized to form favorable interactions with the enzyme environment immediately surrounding the active site. With this hypothesis in mind, we designed a family of structurally related molecules, which contain dipeptide analogs constrained to adopt the extended conformation. Core structural intermediates that are required for the total synthesis of the novel class of HIV-1 protease inhibitors are outlined in Chapter One. Chapter Two discusses the enantioselective synthesis of …

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 Jan 2006

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 Jan 2006

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 Jan 2006

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 Jan 2006

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), …


Fewer Risks, More Benefits: What Governments Gain By Acknowledging The Right To Competent Counsel On State Post-Conviction Review In Capital Cases, Eric M. Freedman Jan 2006

Fewer Risks, More Benefits: What Governments Gain By Acknowledging The Right To Competent Counsel On State Post-Conviction Review In Capital Cases, Eric M. Freedman

Hofstra Law Faculty Scholarship

The acknowledgment that there is a right to the effective assistance of counsel in state post-conviction proceedings would serve the interests of the state and federal governments. Most death penalty states have already decided to provide capital post-conviction counsel but by failing to insist that the representation be competent they have forfeited procedural advantages they would otherwise enjoy in federal habeas corpus litigation, shifted unwarranted costs to the federal government, incurred serious litigation risks for the future, and impaired both the efficiency and the fairness of their systems of criminal justice.
