Examining Emotional Reactivity To Daily Events In Major And Minor Depression, Lauren M. Bylsma

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is a debilitating disorder characterized by significant mood disturbance. In laboratory studies, MDD has been characterized by both blunted positive (PER) and negative emotional reactivity (NER). However, mood disordered persons' emotional reactivity has rarely been studied in naturalistic settings, and it is unknown how less severe forms of depression relate to emotional reactivity. To address these issues, the current study utilized two naturalistic sampling methods (the Day Reconstruction Method and the Experience Sampling Method) to examine PER and NER to daily life events in 35 individuals currently experiencing a major depressive episode (MDD), 26 individuals currently …

Boundary And Longing: Narrative Modes In Mary Shelley’S Frankenstein And The Last Man, Marie Hendry

USF Tampa Graduate Theses and Dissertations

Boundary and desire surround the relationships in Mary Shelley's Frankenstein and The Last Man. The narrative modes of Captain Robert Walton relate his separation to the rest of the world and his need for companionship. Yet, not any companionship will satisfy his longing for connection with a human being; his search revolves around the need of common understanding. This further separates the character of Lionel in The Last Man from humanity in that he is unable to find anyone left on earth after a series of plague, war, and atmospheric anomalies apparently wipe out the human race. His survival …

Secret Servants: Household Domestics And Courtship In Eliza Haywood’S Fiction, Marisa C. Iglesias

USF Tampa Graduate Theses and Dissertations

In Eliza Haywood's fiction, as in eighteenth-century Britain, social restrictions repress the sexual desires of upper class women and men. Therefore, the secret desires of this social class often rely on a different group: domestic servants. Sometimes acting as confidants and other times as active players in the scheming, these servants are privy to the inner secrets of the households in which they live. In Haywood's Love in Excess (1719), Lasselia (1723), Fantomina (1725), and The History of Miss Betsy Thoughtless (1751), the servant class plays significant roles in the narratives.

Since the role of the servant is the central …

Isolation And Functional Characterization Of A Dioxin-Inducible Cyp1a Regulatory Region From Zebrafish (Danio Rerio), Gary T. Zeruth

USF Tampa Graduate Theses and Dissertations

Cytochrome P4501A1 (CYP1A1) is a phase I bio-transformation enzyme involved in the metabolism of xenobiotics via the oxygenation of polycyclic aromatic hydrocarbons (PAHs) including the carcinogen, benzo(a)pyrene. Induction of the CYP1A1 gene is regulated at the transcriptional level and is ligand dependent with the prototypical 2,3,7,8,-tetrachlorodibenzo-p-dioxin (TCDD) being the most potent known inducer of CYP1A1 transcription. This process is mediated by the AHR/ARNT signaling pathway whereby ligand binds AHR in the cytoplasm allowing its translocation to the nucleus where it binds with its hertrodimerization partner, ARNT and subsequently binds DNA at cognate binding sites termed xenobiotic …

The Spatial Distribution Of Geoprivacy Concerns In Florida: A County Level Analysis, Joshua W. House

USF Tampa Graduate Theses and Dissertations

Certain types of spatial data maintained and distributed by counties at taxpayer expense can be used with powerful mapping and analysis software, called Geographic Information Systems (GIS), to compromise an indvidual's locational privacy. The kind of privacy at threat here is referred to as geoprivacy, which is concerned with the rights to prevent disclosure of the location of one's home, workplace, or daily activities. While the availability of accessible and accurate geospatial data has increased geoprivacy concerns in recent years, this threat remains virtually unknown to the general public.

Although previous research has explored various components of the geoprivacy …

This study contributes to theory driven research in strategic communications by using an experimental design to test the influence of six distinct corporate social responsibility initiatives, as identified by Kotler and Lee (2005), on the beliefs, attitudes, and behavioral intention of message receivers, using Fishbein and Ajzen's (1975, 2005) theory of reasoned action as a theoretical framework. According to Fishbein and Ajzen (1975), attitudes about an object are the result of …

Impact Of West Nile Virus On The Natural History Of St. Louis Encephalitis Virus In Florida, Christy L. Ottendorfer

USF Tampa Graduate Theses and Dissertations

The emergence of West Nile virus (WNV) has raised important questions about the capacity of the public health infrastructure to implement surveillance and control programs for WNV and other emerging or re-emerging arboviruses in the United States. Florida's mild climate supports year round enzootic transmission of WNV, St. Louis encephalitis virus (SLEV), and Eastern Equine Encephalitis virus (EEEV). It is unknown what effect the establishment of WNV (in 2001) will have on SLEV transmission in Florida, where these closely related flaviviruses share amplifying hosts, habitats, and vectors.

An Arbovirus Isolation Network was formed to obtain and characterize arbovirus strains collected …

Advances In Magnetic Resonance Electrical Impedance Mammography, Nataliya Kovalchuk

USF Tampa Graduate Theses and Dissertations

Magnetic Resonance Electrical Impedance Mammography (MREIM) is a new imaging technique under development by Wollin Ventures, Inc. in conjunction with the H. Lee Moffitt Cancer Center & Research Institute. MREIM addresses the problem of low specificity of magnetic resonance mammography and high false-positive rates, which lead to unnecessary biopsies. Because cancerous tissue has a higher electrical conductivity than benign tissue, it may serve as a biomarker for differentiation between malignant and benign lesions. The MREIM principle is based on measuring both magnetic resonance and electric properties of the breast by adding a quasi-steady-state electric field to the standard magnetic resonance …

Towards Regenerative Development: A Methodology For University Campuses To Become More Sustainable, With A Focus On The University Of South Florida, Richard Keirs Mcdonald Iii

USF Tampa Graduate Theses and Dissertations

The administrations of several universities have developed strategies to reduce the negative environmental effects created by their institutions. Because no single, comprehensive methodology to guide institutions to sustainability exists, these strategies range widely in scope. As well, the definition of "sustainability" differs for these various institutions, resulting in strategies ranging from small-scale recycling programs to major initiatives to incorporate green building and revamping curricula. This study attempts to create the first comprehensive methodology to guide university campuses and processes to become regenerative. Regenerative systems "produce more resources than needed, provide resources for other projects, and enhance [the] environment" (Bernheim 2003), …

Brca1 185delag Mutant Protein, Brat, Amplifies Caspase-Mediated Apoptosis And Maspin Expression In Ovarian Cells, Joshua D. O'Donnell

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is a deadly disease that kills an estimated 15,000 women annually in the United States. It is estimated that approximately 10% of ovarian cancers are due to familial inheritance. The most commonly mutated genes in familial ovarian cancer are BRCA1 and BRCA2. It has been reported that cells carrying the BRCA1 185delAG mutation undergo an enhanced caspase-3 mediated apoptotic response. Here, we report on the transfection of cDNA coding for the putative truncated protein product of the BRCA1 185delAG mutant gene into BRCA1 wild-type human immortalized ovarian surface epithelial (IOSE) cells and ovarian cancer cells. Cells transfected …

A Comparison Of Community-Based Centers Versus University-Based Centers In Clinical Trial Performance, Cynthia R. Stockddale

USF Tampa Graduate Theses and Dissertations

The success of a clinical trial is largely dependent on the clinical sites that enroll the subjects, complete the follow-up visits, and collect the data. Many clinical trials are conducted using multiple site locations. Choosing such sites to participate in a clinical trial is an important aspect of study implementation. In the past, multi-center clinical trials were conducted mainly using university-based centers. In the last few decades, private practice, or community-based, centers have been included more often in clinical trial research. As more community-based centers participate in clinical trials, it is crucial to examine how these centers might differ from …

Cost-Effectiveness Of Epidural Steroid Injections To Treat Lumbosacral Radiculopathy In Chronic Pain Patients Managed Under Workers’ Compensation, Sheila Mohammed

USF Tampa Graduate Theses and Dissertations

No conclusive evidence exists to determine that epidural steroid injections (ESIs) provide lasting improvements in chronic pain due to herniated discs, in the Workers' Compensation population. Recently, an article by Armon et.al was published by the American Academy of Neurology, which stated that the routine use of ESIs is not recommended and that further studies are needed to elucidate this controversy (Armon, Argoff, Samuels, & Backonja, 2007).

In 1998, back pain in the United States was estimated to have incurred total health-care expenditures of $90.7 billion. Medicare part B. claims in 1999 for 40.4 million individuals amounted to $49.9 million …

Counting Or Discounting Television Information: An Examination Of Viewer Perceptions About Old-Age From A Cognitive Processing Perspective Of Cultivation Effects, Lynda Pasteur

USF Tampa Graduate Theses and Dissertations

Cultivation theory (Gerbner & Gross, 1976) suggests that the cumulative effect of heavy exposure to television's underrepresentation and negative portrayal of people 65+ as sexless, insignificant, and comical can cause people to assume such television-like perceptions of the age group in the real world. This study's purpose was to explore not only television's cultivation effect on viewers' perceptions of the number and nature of people 65+, but also the psychological processes that are expected to mediate this effect. As an extension of Shrum, Wyer, and O'Guinn's (1998) study on the role of source discounting in cultivation, this quasi-experiment employed three …
