Auditory Sensitivity Of Sergeant Majors (Abudefduf Saxatilis) From Post-Settlement Juvenile To Adult, Sarah A. Egner

USF Tampa Graduate Theses and Dissertations

There is much evidence supporting the idea that pelagic larvae of coral reef fishes are active participants in their dispersal and return to a reef, however, the mechanisms used to navigate are still uncertain. It has been proposed that sensory cues, such as hearing, play a role. Sound is a potentially important cue for organisms in marine environments, especially in noisy environments like coral reefs. Sensory organs, including otolithic organs, of most coral reef fish form within the first few days of life. The auditory brainstem response (ABR) technique was used to measure hearing on a wide size range of …

Biological Indicators Of Wetland Health: Comparing Qualitative And Quantitative Vegetation Measures With Anuran Measures, Shannon M. Gonzalez

USF Tampa Graduate Theses and Dissertations

Understanding wetland responses to human perturbations is essential to the effective management of Florida's surface and ground water resources. Southwest Florida Water Management District (SWFWMD) Rules (Chapter 40D-2.301(c) FAC) prohibit adverse environmental effects to wetlands, fish and wildlife caused by groundwater withdrawal. Numerous studies have documented the responses of biological attributes across taxa and regions to human disturbance. Biological assessment can provide information about ecological condition. Based on long-term monitoring conducted by the SWFWMD, the anthropogenic changes observed on the Starkey Wellfield are attributed to groundwater withdrawal.

Biological indicators are species, species assemblages, or communities whose presence, abundance, and condition …

The Artist And Her Muse: A Romantic Tragedy About A Mediocre And Narcissistic Painter Named Rachel Hoffman, Rachel Gavronsky Hoffman

USF Tampa Graduate Theses and Dissertations

Imagine a theater. Build one in your mind. I do not care if it is the largest theater in the universe or if it is the size of a shoebox. The theater can be an elaborate construction with gilded cherubs and priceless jewels. If you would prefer the theater to be a minimal design, imagine it that way. Maybe the theater is made out of glass or crystal. You can be all alone in the theater or maybe you are seated next to an alien, a cave man, or a robot.

As the curtain rises an enormous pipe organ is …

Comparative Analysis Of Serologic Assays For The Detection Of Antibodies To Eastern Equine Encephalomyelitis Virus In Sentinel Chickens, Christy L. Voakes

USF Tampa Graduate Theses and Dissertations

Florida's mild climate supports year round enzootic transmission of arthropod-borne (arbo) viruses, such as St. Louis Encephalitis virus (SLEV), West Nile virus (WNV), and Eastern Equine Encephalomyelitis virus (EEEV). First isolated in 1960 from two Florida blue jays, Highlands J virus (HJV) is endemic to the state and vectored by the same mosquitoes as EEEV (Henderson et al, 1962). EEEV and HJV are both alphaviruses, but HJV is not pathogenic to humans, occasionally causes encephalitis in horses, and is a recognized pathogen in some bird species (turkeys, emus, etc) (Cilnis et al, 1996).

The Florida Sentinel Chicken Arboviral Surveillance …

From Just War To Just Peace: Re-Visioning Just War Theory From A Feminist Perspective, Naomi Malone

USF Tampa Graduate Theses and Dissertations

This paper studies the history of just war theory and critiques it from various feminist perspectives. Using a definition of war as inseparable from the system within which it is embedded, the paper contends that just war theory has been incorporated into the realist paradigm that predominates current political thought, making it susceptible to manipulation. Most importantly, this usurpation has shifted just war theory's focus from jus ad bellum to jus in bello considerations, seriously weakening its deterrent effects on war. The paper proposes its replacement with a just peace theory, discussing several existing frameworks and explaining the important part …

Concerning Theories Of Personal Identity, Patrick, Bailey

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory (i.e. a theory about theories) of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the concept of personhood.

By demonstrating that our understanding of personhood is relative to frameworks …

A Control Layer Algorithm For Ad Hoc Networks In Support Of Urban Search And Rescue (Usar) Applications, Venkatesh Ramarathinam

USF Tampa Graduate Theses and Dissertations

Ad hoc networks have gained significant importance and gathered huge momentum within the wireless network research community. We explore the novel idea of applying ad hoc networking for urban search and rescue operations. Several algorithms have been proposed and implemented for routing in ad hoc networks and their performance have been thoroughly analyzed. But none of the prior work deals specifically for search and rescue operations, which entail certain specific criteria such as prevention of node loss, maximizing the area of coverage and constant and instantaneous access to a main controller.

In this thesis, we propose a centralized and adaptive …

The sample included four news Web sites considered to be highly converged with their print and broadcast counterparts (TBO.com, chicagotribune.com, DallasNews.com, and Azcentral.com), one newspaper Web site not affiliated with a broadcast media organization (buffalonews.com), and one broadcast news Web site not affiliated with a print news organization (kfmb.com). A multimedia and interactivity score was given to each Web site based on the quantity of these components each site used. Both kfmb.com (a non-converged organization) …

Ammonia Flux At The Air/Water Interface Of Tampa Bay, Constance Anne Mizak

USF Tampa Graduate Theses and Dissertations

An ammonia emissions inventory discovered that 90% of the ammonia emitted from Pinellas, Hillsborough, and Polk counties, originated from the latter two counties. This finding is significant and suggests that a substantial portion of the ammonia deposited to Tampa Bay is transported with easterly air masses.

Ammonia and ammonium concentrations at the coastal Gandy Bridge site were seasonally and diurnally consistent, but the rural Sydney site showed greater variability. It was determined that wind direction was the most influential parameter affecting the Gandy Bridge site, which supports the hypothesis that an advection of ammonia from the east is a major …

Distribution, Metabolism And Trophic Ecology Of The Antarctic Cydippid Ctenophore, Callianira Antarctica, West Of The Antarctic Peninsula, Kerri M. Scolardi

USF Tampa Graduate Theses and Dissertations

The distribution, abundance, chemical composition, metabolism, and feeding ecology of the tentaculate ctenophore, Callianira antarctica (Chun 1897), were investigated during austral winter 2001and autumn & winter 2002, in the vicinity of Marguerite Bay west of the Antarctic Peninsula. Callianira antarctica had a widespread distribution during autumn and winter, and variable abundance (0.02 to 2.6 ind. m-2) during winter 2001 associated with specific circulation features. Size frequency distributions for autumn and winter suggest that more than half of the C. antarctica population may have experienced 'degrowth' during winter due to low food availability. Callianira antarctica is a fairly robust ctenophore with …

Synthesis And Characterization Of Potential Drug Delivery Systems Using Nonionic Surfactant “Niosome”, Sukit Leekumjorn

USF Tampa Graduate Theses and Dissertations

Niosomes are synthetic microscopic vesicles consisting of an aqueous core enclosed in a bilayer consisting of cholesterol and one or more nonionic surfactants. They are made of biocompatible, biodegradable, non-toxic, non-immunogenic and non-carcinogenic agents which form closed spherical structures (self assembly vesicles) upon hydration. With high resistance to hydrolytic degradation, niosomes are capable of entrapping many kinds of soluble drugs while exhibiting greater vesicle stability and longer shelf life.

In this work, a potential drug delivery system has been designed, synthesized and characterized. For the synthesis of niosomes, a hydration process was developed with varying design parameters such as mass …

The Antidepressant Drug Tianeptine Blocks Working Memory Errors: Pharmacological And Endocrine Manipulations Of Stress-Induced Amnesia In Rats, Adam Marc Campbell

Chemical Investigation Of Three Antarctic Marine Sponges, Young Chul, Park

USF Tampa Graduate Theses and Dissertations

This thesis describes the chemical investigation of three marine sponges from Antarctica and the total syntheses of natural products erebusinone (12) and its derivative, erebusinonamine (52). Investigation of the yellow Antarctic marine sponge Isodictya setifera resulted in the isolation of two secondary metabolites, purine analog (32) and 3-hydroxykynurenine (24). Chemical investigation of Isodictya setifera led to the isolation of six secondary metabolites which included 5-methyl-2-deoxycytidine (25), uridine (28), 2-deoxycytidine (31), homarine (37), hydroxyquinoline (33), 3-hydroxykynurenine (24). The latter two compounds …

Human Topoisomerase Ii Alpha Nuclear Export Is Mediated By Two Crm-1 Dependent Nuclear Export Signals, Joel G. Turner

USF Tampa Graduate Theses and Dissertations

Resistance to chemotherapeutic drugs is a major obstacle in the treatment of leukemia and multiple myeloma. We have previously found that myeloma and leukemic cells in transition from low-density log phase conditions to high-density plateau phase conditions exhibit a substantial export of endogenous topoisomerase II alpha from the nucleus to the cytoplasm. In order for topoisomerase-targeted chemotherapy to function, the topoisomerase target must have access to the nuclear DNA. Therefore, the nuclear export of topoisomerase II alpha may contribute to drug resistance, and defining this mechanism may lead to methods to preclude this avenue of resistance. In the current report, …

Parameterization Of The Light Models In Various General Ocean Circulation Models For Shallow Waters, Hari Warrior

USF Tampa Graduate Theses and Dissertations

Solar energy is incident on the earth's surface in both short-wave and long-wave parts of the spectrum. The short-wave part of the spectrum is of special interest to oceanographers since the vertical distribution of temperature in the top layer of the ocean is mostly determined by the vertical attenuation of short-wave radiation. There are numerous studies regarding the temperature evolution as a function of time (see Chapter 2 for details). The diurnal and seasonal variation of the heat content (and hence temperature) of the ocean is explored in this thesis. The basis for such heat budget simulation lies in the …

A Comparison Of Centrifugal Forces To Reduce The Inhibitory Effects Of Food Matrixes On Reverse Transcriptase Polymerase Chain Reaction For The Detection Of Food Borne Viruses, Kristina Kim Carter

USF Tampa Graduate Theses and Dissertations

The CDC estimated that foodborne infections resulted in approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths per year in the United States (Mead, 1999). There are over 200 known diseases caused by viruses, bacteria, parasites, toxins, metals, or prions that can be transmitted through food. Of these illnesses caused by foodborne disease, the CDC estimates that 38.6 million cases are from identifiable pathogens and 30.9 million of these cases are caused by viruses. Hence, approximately 80% of foodborne illnesses of known etiology result from viral transmission (Mead, 1999). Viral gastrointestinal illness may be caused by virus families such as: …

Weblogs And The Technology Lifecycle: Context, Geek-Chic And Personal Community, James M. Milne

USF Tampa Graduate Theses and Dissertations

Weblogging is an Internet social practice that became known as a technology. This project investigated weblogging (blogging) as an example of a media technology that arose under particular historical circumstances. To investigate this, blogs were examined in detail, participant-observation was used to construct and run a blog, and practicing bloggers were interviewed. The study found that blogging, like all technology, originates within existing social practice (context); has a diffusion process that causes it to spread between people (Geek-Chic); and leads to certain social outcomes (Personal Community). This is seen as a general pattern for the lifecycle of technology, serving to …

Detection And Quantification Of Karenia Brevis By Carbon Fixation Gene Expression Analysis, Michael Alan, Gray

USF Tampa Graduate Theses and Dissertations

Karenia brevis (Davis cf. Hansen & Moestrup = Gymnodinium breve) is the non-peridinin containing dinoflagellate responsible for many harmful algal blooms (red tides) in the Gulf of Mexico. These recurrent blooms can have significant negative ecological, economic, and human health impacts including fish kills, tainting of shellfish, poisoning of marine mammals, loss of tourism revenue due to beach closures, and respiratory distress and food poisoning in humans.

A method for detection of Karenia brevis was developed based upon amplification of the mRNA for the plastid-encoded gene of the carbon fixing enzyme ribulose 1, 5-bisphosphate carboxylase/oxygenase (RuBisCO) large subunit (rbcL). …

Shakespeare’S Midsummer Fairies: Shadows And Shamen Of The Forest, Patricia, Roy

USF Tampa Graduate Theses and Dissertations

Recent interest in environmental crises has inspired literary critics to consider how the history of ideas shapes our current ecological debates. Shakespeare's A Midsummer Night's Dream sets the stage for assessing how Renaissance attitudes towards nature have influenced current ideologies. While the play appears to be a fantasy, it reveals a relationship with nature, both physically and figuratively. The play's excursion into the woods shows an attempt to heal human relationships. Shakespeare's use of the imagery of nature argues in favor of the green world, for it is a world inhabited by shadows and shamen -- or, as Shakespeare calls …

Mechanisms Of Ss-Amyloid Clearance By Anti-Aß Antibody Therapy, Donna Marie Wilcock

USF Tampa Graduate Theses and Dissertations

Alzheimers disease (AD) is defined as a progressive neurodegenerative disorder that gradually destroys a persons memory and ability to learn. There are three pathological hallmarks of the disease which are necessary for diagnosis of AD, these are; extracellular amyloid plaques composed of [beta]-amyloid (A[beta]) protein, intracellular neurofibrillary tangles and neuronal loss. Amyloid plaques exist as both compact deposits which stain with Congo red and more numerous diffuse deposits. Active immunization against A[beta] 1-42 or passive immunization with monoclonal anti-A[beta] antibodies reduces amyloid deposition and improves cognition in APP transgenic mice.

Over several studies of active immunization in APP+PS1 transgenic mice …
