Source Credibility And Public Information Campaigns: The Effect Of Audience Evaluations Of Organizational Sponsors On Message Acceptance, Deena G. Kemp

USF Tampa Graduate Theses and Dissertations

This study establishes a link between research on organizational source credibility and the effects of public information campaigns. Research has established that source credibility is one factor audiences evaluate when responding to messages and that credible information sources enhance message acceptance, while untrustworthy sources can interfere with desired message effects. Although source credibility studies have typically focused on the person delivering a message, recent studies indicate that audience perceptions of the organization sponsoring a message has a direct effect on message acceptance as well. Additionally, a few studies indicate that non-profit sources of health information are viewed as more credible, …

Crystallization Studies Of Epigallocatechin Gallate, Sheshanka Kesani

USF Tampa Graduate Theses and Dissertations

Flavonoids are a long and well known class of natural products. Their potential health benefits can be attributed to their antioxidant activity, and modulation of cell signaling pathways. Green tea one of the most widely consumed beverages, consist of flavonoids such as catechins and tannins. Epigallocatechin gallate (EGCG) the major catechin of green tea exhibits multiple health benefits due to its antioxidant nature. The radical scavenging activity of EGCG is attributed to its structure. Therefore, a study on molecular features of EGCG would provide valuable information on structural modifications, which may change the physiochemical properties such as bioavailability and solubility. …

Sol-Gel Immobilized Cyano-Polydimethylsiloxane And Short Chain Polyethylene Glycol Coatings For Capillary Microextraction Coupled To Gas Chromatography, Sameer M. Kulkarni

USF Tampa Graduate Theses and Dissertations

Two highly polar sol-gel coatings were developed for capillary microextraction (CME). One of the coatings contained cyanopropyl-polydimethylsiloxane (CN-PDMS) and the other low molecular weight polyethylene glycol. These highly polar coatings were immobilized via sol-gel chemistry allowing for direct chemical bonding to the inner surface of fused silica capillaries. These sol-gel coated microextraction capillaries were employed in CME for solvent-free microextraction and preconcentration of trace analytes (polar, moderately polar, and nonpolar) from aqueous matrices. CN-PDMS and short chain PEG extraction phases exhibit both polar and polarizable characteristics. Therefore, both sol-gel CN-PDMS and short chain sol-gel PEG coatings were able to extract …

The Turn Of The Screw’S Debated Phantasms: The Role Of The Fantastic In The Creation Of Peter Quint And Miss Jessel, Susan Savage Lee

USF Tampa Graduate Theses and Dissertations

When Henry James sat down to write his "amusette" as he called The Turn of the Screw (1898), he created various ambiguities in the text as a means of confusing and surprising his readers or, in other words, catching them off guard. Over a century later, the mysterious ambiance surrounding the novella has not become any clearer. While critics from Edmund Wilson to Edna Kenton have analyzed the work from a somewhat psychoanalytical perspective, stating that the ghosts of Miss Jessel and Peter Quint are merely figments of the governess's imagination, Tzvetan Todorov and Rosemary Jackson examine James's work through …

Faust In Lolita: Composing Sins, Souls, And Rhetorical Redemption, Aurora Mackey

USF Tampa Graduate Theses and Dissertations

Goethe's Faust and Nabokov's Humbert both are erudite, middle-aged European scholars who, experiencing a convergence of academic and existential ennui, set eyes upon a young girl and instantly are consumed with lust. In both works the girls' widowed mothers die as a result of the protagonists' lustful intentions; a cross-country flight ensues; the once-respected scholars are wanted for murder; and Gretchen and Lolita each suffer from their sexual and emotional objectification. But the connections between Goethe's play and Nabokov's novel extend far beyond plot points, or even their decidedly different receptions in early 19th century Germany versus mid-20th century America. …

Achieving Sobriety: A Narrative Investigation Of Women, Identity, And Relationships, Cara T. Mackie

USF Tampa Graduate Theses and Dissertations

In this dissertation, I explore the question of how women alcoholics achieve sobriety. Using narrative inquiry, I focus on the identity transformation that must occur in order to maintain sobriety and how a drinking self is deconstructed and reconstructed as a sober self. Today, alcoholism is still viewed as stigmatizing in our society and in all Western cultures. The stigma of alcoholism makes it difficult for alcoholics to communicate their experiences to people who have not had similar experiences. However, storytelling in the presence of supportive people has been shown to be a prominent factor in the process of recovery …

Cogito Ergo Doceo: A Cross-Case Study Of Latin Teacher Cognition In Technology-Rich Communities Of Practice, Ramã³N Anthony Madrigal

USF Tampa Graduate Theses and Dissertations

This empirical research study investigated the phenomenon of ancient language teacher cognition in the technology-rich contexts of two secondary teachers of Latin. Although one teacher was an inexperienced teacher working in a traditional, face-to-face classroom in an independent school, the other teacher was an experienced teacher working at a public virtual school. Features of teacher cognition, such as pre-active planning and inter-active decision-making were examined from a communities-of-practice theoretical perspective (Wenger, 1998). An exploratory, sequential mixed-methods research design was implemented in this cross-case study. Among the research findings that emerged from this investigation was the notion of the expedient integration …

Ethyl Methacrylate And Methyl Methacrylate Exposure Among Fingernail Sculptors, Adam Marty

USF Tampa Graduate Theses and Dissertations

Fingernail sculptors may be exposed to ethyl methacrylate and methyl methacrylate in their workplace. The literature suggests that these chemicals may cause sensitization in individuals who are exposed to sufficient quantities. Cases of occupational asthma and allergic contact dermatitis have been reported among persons who work with these chemicals. Little personal exposure data exists on nail technicians' exposures to these chemicals, especially ethyl methacrylate. The literature suggests that the industrial hygiene practices used for methyl methacrylate also be applied to ethyl methacrylate since more is known about methyl methacrylate. Previous exposure studies have revealed relatively low exposures to these chemical. …

Moving Thumos: Emotion, Image, And The Enthymeme, Eric D. Mason

USF Tampa Graduate Theses and Dissertations

This dissertation connects classical theories regarding the enthymeme and thumos (a Greek word commonly translated as "heart," "mind," or one's "capacity for emotion") to modern theories of images and emotion in order to reconsider the central role of visual discourse in persuasion, ideology, and subject formation. Since "enthymeme" comes from en and thymos, meaning "in heart," etymologically the enthymeme is an argument that is realized in an individual's thumos.

This dissertation thus attempts to establish the notion of thumos in rhetorical studies by developing a theory of visual enthymemes.The understanding of the enthymeme used within this dissertation works less from …

USF Tampa Graduate Theses and Dissertations

A coupled, three-dimensional, time-dependent numerical model of water circulation, spectral light, plankton dynamics, nutrient/CDOM loadings, and zooplankton grazing provided an assessment of the factors affecting the growth and maintenance of red tides on the west Florida shelf (WFS). The coupled biophysical model consisted of state variable quantities for temperature, salinity, horizontal/vertical velocity components, turbulent diffusion, spectral light, colored dissolved organic matter (CDOM), dissolved organic and inorganic carbon, particulate silica, four dissolved inorganic nutrient pools (nitrate, ammonium, phosphate, and silicate), and four phytoplankton groups (diatoms, microflagellates, non-toxic dinoflagellates, and the red tide organism Karenia brevis).

The model also included a complex …

Depressive Symptomatology, Patient-Provider Communication, And Patient Satisfaction: A Multilevel Analysis, Lorraine Marie Novosel

USF Tampa Graduate Theses and Dissertations

Depression can be a profoundly disabling and costly disorder and is a major public health concern. Despite the efficacy of treatment options, it is often unrecognized, under-diagnosed, and inadequately treated in primary care settings. Research on patient-provider communication supports the connection among the quality of the patient-provider interaction, patient behavior, and health outcomes. The purpose of this study was to systematically examine the impact of patients' depressive symptoms on the patient-provider relationship, patient-provider communication, and patient satisfaction with the primary care office visit. One hundred twenty three patient-provider encounters were audiotaped and coded using the Roter Interaction Analysis System (RIAS). …

The Impact Of Fidelity And Innovations On Healthy Families America Programs, Ashley E. Nixon

USF Tampa Graduate Theses and Dissertations

Fidelity to a program model and innovations added to the program model have been found to positively impact large scale program expansion and implementation (Blakely et al., 1987). Research examining the effectiveness of Healthy Families America (HFA) programs has been hindered by the differences that exist among HFA programs. This study examines the impact program fidelity and innovations have on outcome measures of updated immunizations, primary medical care providers, and participant retention for 102 HFA sites. Factor analysis and regression were used to analyze archival data. Results indicate that fidelity was positively related to percentage of participants with updated immunizations …

Forging Identities Through Style: Elite Interaction And Identity Formation At Late Classic (Ad 650-900) Palmarejo, Northwest Honduras, Claire Novotny

USF Tampa Graduate Theses and Dissertations

The representation of social affiliation is dependent upon material signifiers that can serve as communicative links between individuals or communities. This study evaluates the material manifestation of an elite social identity during the Late Classic (AD 650-900) period at the site of Palmarejo, northwest Honduras. Previous studies on social identity in prehistory point to the importance of site plans, monumental architecture, ceramics, and human burials in conveying sociocultural messages. A regional comparison of these types of data is made between Palmarejo and three coeval sites in northwest Honduras, La Sierra, El Coyote, and Las Canoas. I argue that the chosen …
