Two open-ended interviews were conducted. During the first interview, participants are asked to "Please think of a specific time when you had something important to say, and although it was difficult, you did speak up and say what you thought. In as much detail as possible, describe that experience." During the second interview, each girl was asked if she "... feel[s] …

Sound Localization Abilities Of Two Florida Manatees, Trichechus Manatus Latirostris, Debborah E. Colbert

USF Tampa Graduate Theses and Dissertations

Florida manatees (Trichechus manatus latirostris) live in the shallow, often turbid inland and coastal waters of the southeastern United States. Since their vision is poor (Bauer et al., 2003), other senses probably guide orientation. Previous studies have found that manatees can hear over 40 kHz (Gerstein et al., 1999) and have the capacity for rapid auditory temporal processing (Mann et al., 2005). However, it is not known if manatees have the ability to localize underwater sounds.

Two Florida manatees were trained to identify underwater sound source locations using a four-choice discrimination paradigm. Three broad-band signals ( 0.2 - …

Promotoras Of The U.S.-Mexico Border: An Ethnographic Study Of Culture Brokerage, Agency, And Community Development, Ricardo B. Contreras

USF Tampa Graduate Theses and Dissertations

This study examines promotoras from the U.S.-Mexico border. Promotoras are women who live in colonias throughout the border area and who are employed by service provider and community development organizations to do health-related outreach and education with colonia residents. The role of promotoras can be seen from the perspective of culture brokerage; that is, they are mediators between local communities and external actors such as service providers and agencies of the government. As culture brokers, promotoras facilitate the relationship among the local communities, and the system of services and outside resources. The study proposes a conceptual framework through which programs …

Promoting And Preventing Alzheimer’S Disease In A Transgenic Mouse Model: Apolipoprotein E And Environmental Enrichment, David Antonio Costa

USF Tampa Graduate Theses and Dissertations

Besides age, inheritance of the apoE-ε4 allele is the main risk factor for late-onset AD. To determine the role of apoE in amyloid deposition, we studied mice expressing both mutant human amyloid ß-protein precursor (APP) and presenilin 1 (PS1) that were either normal or knocked-out for apoE. By 7 months, amorphous Aß deposition developed equally in both lines, indicating that Aß alone is sufficient for deposition to occur. In contrast, filamentous amyloid deposition was catalyzed at least 3000 fold by apoE. Electron micrographs further illustrate the filamentous nature of these plaques. These results and other, behavioral, data indicate that the …

The Outsider Within The Victorian Community: Nicholas Bulstrode In Middlemarch And Michael Henchard In The Mayor Of Casterbridge, Marian D. Conklin

USF Tampa Graduate Theses and Dissertations

Many have written about the theme of interconnection in George Eliot’s Middlemarch, where individual lives and fates are woven into the larger life of the community, but few have written about this theme in relation to The Mayor of Casterbridge, Thomas Hardy’s fictional and historical depiction of Dorchester and the larger area of Wessex. Hardy’s novel about “the life and death of a man of character,” is a complex and psychological characterization, but it also is representative of a particular province during a time of rapid change in community structure, just as Middlemarch is. I would like to …

Transformational Leadership, Leader-Member Exchange (Lmx), And Ocb: The Role Of Motives, Patrick W. Connell

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate the impact of employee motives regarding select leadership-OCB relationships. Based on previous research, it was hypothesized that the relationships observed between transformational leadership and various dimensions of OCB would be mediated by subordinate Organizational Concern. In contrast, the relationship between LMX-quality and subordinate Altruism was predicted to be either mediated or moderated by subordinate Prosocial Values.

Two hundred and one part-time and full-time employees (subordinates and supervisors) served as participants in this study, representing a total of 13 organizations in the Southeast United States. Results were based on a final sample of …

The Effects Of Response Cards On The Performance And Generalization Of Parenting Skills, Bennie L. Colbert

USF Tampa Graduate Theses and Dissertations

Previous research has provided convincing evidence of the efficacy of behavior analytic interventions to improve parenting skills with biological parents, however many studies lament generalization failure from training to home settings. Previous research has also examined the effects of response card use with children at various grade levels and with post-secondary students with a sole focus on academic outcomes. This study examined the effects of color coded response cards on active student responding and parenting skills proficiency of three foster parents in a parent training program and generalization of these skills to their homes. During baseline, participants role-played their responses …

The Power Of The Spoken Word: Literature In The American Mass Media Of The 1990s, Codrina Cozma

USF Tampa Graduate Theses and Dissertations

The 1990s saw a climax of literature representations in what Ong called the secondary orality, particularly in film, television, and radio; for instance, the film industry produced a number of adaptations of novels that had been accepted into the American literary canon, while television and radio marketed literature through book clubs and literary shows. All these literary productions mediated through film, radio, and television are referred to in this study as mediatized literature.

The argument of this dissertation is that 1990s U.S. mediatized literature constitutes a post-modern re-enactment of the traditional oral literature that initially emerged on U.S. territory …

Dissecting Out The Contribution Of Cognitive, Social, And Physical Activities To Environmental Enrichment’S Ability To Protect Alzheimer’S Mice Against Cognitive Impairment, Jennifer R. Cracchiolo

USF Tampa Graduate Theses and Dissertations

Retrospective studies suggest that lifestyle activities may provide protection against Alzheimer s Disease (AD). However, such studies can be inaccurate and prospective longitudinal studies investigating lifestyle protection against AD are both impractical and impossible to control for. Transgenic (Tg+) AD mice offer a model in a well controlled environment for testing the potential for environmental factors to impact AD development. In an initial study, Tg+ and non-transgenic (Tg-) mice were housed in either environmentally enriched (EE) or standard housing (SH) from 2-6 months of age, with a behavioral battery given during the last 5 weeks of housing. In the Morris …

Effects Of Hyperoxia In Alzheimer’S Transgenic Mice, April Cox

USF Tampa Graduate Theses and Dissertations

An association between major surgery in the elderly and precipitation of Alzheimer’s disease (AD) has been reported. Hyperoxia (100%) oxygen is commonly administered after surgery to increase the oxygen content of blood. However, hyperoxia is a potent cerebral vasoconstrictor and generator of free radicals, as is β-amyloid (Aβ). This study was aimed at examining behavioral, neuropathological, and neurochemical effects of hyperoxia treatments in APPsw transgenic mice (Tg+), which have elevated brain Aβ levels by 3-4 months of age but are not yet cognitively-impaired. At 3 months of age, Tg+ mice were pre-tested in the radial arm water maze (RAWM) task …

Sample problem sets were written by the author and a few chemical engineering students.

These web pages were then used as a basis to test the effectiveness of the webbased interactive problem sets for two engineering courses. Initial findings are presented illustrating the student’s results along with results …

Assessment Of The Community Healthcare Providers' Ability And Willingness To Respond To A Bioterrorist Attack In Florida, Jeffrey S. Crane

USF Tampa Graduate Theses and Dissertations

Previous findings have demonstrated that the preparedness and infrastructure of the public health system are inadequately developed for a biological and/or chemical terrorism attack. (1-4) Chen et al. reported that those primary care providers that would have to respond to such an attack do not feel prepared to diagnose and manage such an event.(5)

This research was an observational study using e-mail/web based survey to assess the levels of preparedness (PL) and willingness to respond (WTR) to a bioterrorism attack, and identify factors that predict PL and WTR of Florida community healthcare providers. The conceptual framework and questionnaire was designed …

Early Learning Experiences: Education With Coaching And The Effects On The Acquisiton Of Literacy Skills In Preschool Children, Dale Lynn Cusumano

USF Tampa Graduate Theses and Dissertations

Reading to learn becomes a difficult task for children if they have not become proficient at comprehending written text. It was hypothesized that, for some children, reading difficulties may have been averted had they been reared in homes or participated in early childhood settings where literacy-based activities, interactions, or materials were prevalent. The purpose of this study was to examine the impact that training early childhood educators in researchbased early literacy instructional strategies (within the HeadsUp! Reading curriculum ñ HUR) had on the development of early reading skills in the preschool children they taught. Further examination also identified the impact …

Theoretical And Experimental Investigation Of Phase Behavior Of Polymeric Systems In Supercritical Carbon Dioxide And Their Modeling Using Saft, Ratka Damnjanovic

USF Tampa Graduate Theses and Dissertations

Environmentally friendly processing of materials is becoming an increasingly important consideration in a wide variety of emerging technologies. Polymer processing, in particular, has benefited tremendously in this venue from numerous advances achieved using high-pressure carbon dioxide (CO₂) as a viscosity modifier, plasticizing agent, foaming agent, and reaction medium. Polymer processing in supercritical fluids has been a major interest for a portfolio of materials processing applications including their impregnation into porous matrices. Also, SCF solvents are being examined as a media for polymerization processes, polymer purification and fractionation, and as environmentally preferable solvents for solution coatings. Pressurized CO_{2 …}

Coral Reef Assessment: An Index Utilizing Sediment Constituents, Camille A. Daniels

USF Tampa Graduate Theses and Dissertations

Resource managers need inexpensive bioindicators to evaluate the health of coral reef ecosystems and to inform decisions on when and where to utilize more expensive assessment techniques. Following USEPA Guidelines for Evaluating Ecological Indicators, I developed the SEDCON Index (SI), a rapid-assessment protocol which utilizes reef sediment composition to assess the integrity of coral-reef communities. Key advantages of this index are that it entails non-destructive sampling and is applicable to reefs worldwide. The underlying assumption of the index is that community structure is reflected by proportions of recognizable remnants of calcareous shells and skeletal remains of mixotrophic (zooxanthellate corals and …

Investor And Worker Response To Corporate Downsizing Of Esop Companies: Wealth Effects, Productivity, And Performance, Jeanean J. Davis-Street

USF Tampa Graduate Theses and Dissertations

Finance, economic and management literature document the reduced agency problems, increased productivity, and greater financial benefits that accrue to firms that adopt Employee Stock Ownership Plans, (ESOPs). The literature also documents the increased agency problems, decreased employee productivity, and poor operating performance that usually accompany corporate downsizing activity. To date, none of the studies have examined the effect that downsizing decisions have on companies with existing ESOP plans; this dissertation fills that empirical void. In this study, two essays are presented that examine the effect of corporate downsizing on ESOP versus non-ESOP firms.

In the first essay, I investigate the …

Participants in this study were members of professional associations and were recruited from internet listserves. They consisted of 485 employees and 176 co-workers. This study used a matching technique to link participant and co-worker data and was the first study to assess multiple perspectives of marketability. Results demonstrated the relationships of human capital variables, positivity traits, proactive career behaviors, the environment and industry characteristics on internal and external marketability. Interestingly, not all predictors related to both internal and external …

Fire And Ice In The Age Of Innocence, Alisa Mariva Deborde

USF Tampa Graduate Theses and Dissertations

This study will explore the dichotomy of culture and psychological landscape in Edith Wharton’s The Age of Innocence. To lay the foundation for this study, I first consider how Ms. Wharton often employed dichotomy in her own life: her role as socialite and author, woman of old New York and European maverick, and her life as spouse or beloved. Compartmentalizing her life’s roles prevented her from having to compromise the distinct qualities of each paradigm. Similarly, in The Age of Innocence, Ellen and May are completely opposite representations of life and culture in the 1870’s who cannot happily coexist …

Formation Of Nanocoatings By Laser-Assisted Spray Pyrolysis And Laser Ablation On 2d Gold Nanotemplates, Gayan S. Dedigamuwa

USF Tampa Graduate Theses and Dissertations

This thesis describes a new Laser-Assisted Spray Pyrolysis technique developed to grow nanoparticle coatings with controllable particle sizes. In this method, droplets of a precursor formed by a nebulizer are injected into a growth chamber using SF6 carrier gas. An experimental study and a computational model to investigate the particle size dependence on various growth parameters have been carried out. The results show that heating of 1.5µm droplets of metalorganic precursor in a carrier gas using a CO2 laser resulted in the formation of TiC and Fe3O4 particles with diameters in the range of 50- 60nm. Also the results show …

Pacap And Vip Modulation Of Neuroexcitability In Rat Intracardiac Neurons, Wayne I. Dehaven

USF Tampa Graduate Theses and Dissertations

Autonomic control of cardiac function depends on the coordinated activity generated by neurons within the intracardiac ganglia, and intrinsic feedback loops within the ganglia provide precise control of cardiac function. Both pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) are important regulators of cell-to-cell signaling within the intracardiac ganglia, and PACAP and VIP action on these ganglia, mediated through associated receptors, play an important role in the regulation of coronary blood flow, cardiac contraction, relaxation, and heart rate. Results reported here using PACAP and VIP provide direct evidence of some of the complex signaling which occurs in neurons …

Misogyny And (Mis)Representation: The Female Subject In The Poetry Of José De Espronceda, Cristina L. Delano

USF Tampa Graduate Theses and Dissertations

This work explores the portrayal of the female subject in the work of the Spanish Romantic poet. José de Espronceda, This study will analyze the misogynistic representation of women and the denial of female subjectivity.

The first chapter discusses the biographical, historical and literary contexts of Espronceda’s work. This section will discuss Romantic notions of subjectivity, as well as the ambivalence towards the women during the 19th century. This ambivalence produced a conflict that was reflected in the representation of women as either pure angels or vile demons.

The first work that will be discussed is the poem “A Jarifa …

Extrapulmonary Tuberculosis In Hiv-Positive And Hiv-Negative Children In Haiti: A Hospital-Based Investigation, Marie F. Denis

USF Tampa Graduate Theses and Dissertations

Introduction: Globally, one in four persons infected with the human immunodeficiency virus (HIV) who are living with the acquired immunodeficiency syndrome (AIDS) will die of tuberculosis (TB). The estimated number of HIV-infected children who die of tuberculosis, especially extrapulmonary TB (EPTB), in Haiti, is only loosely based on facts or investigation. This study proposes to describe demographics of children with EPTB in a pediatric TB hospital in Haiti. The objectives are two-fold. The first objective is to describe the population of children discharged from Grace Children’s Hospital with a confirmed diagnosis of tuberculosis overall, and broken down by whether or …

Antecedents And Consequences Of Emotional Dissonance: Understanding The Relationships Among Personality, Emotional Dissonance, Job Satisfaction, Intention To Quit And Job Performance, Laurie K. Diamond

USF Tampa Graduate Theses and Dissertations

The primary goal of this research was to explore the antecedents and consequences of emotional dissonance for debt collectors. The antecedents were personality factors (extraversion, anger, conscientiousness and agreeableness) and prosocial factors. The consequences of emotional dissonance were job satisfaction, intention to quit and job performance. A path model was developed to explain the relations among the studyís measures in a sample of 188 full-time debt collectors. The path analysis results failed to show strong relations between personality and emotional dissonance. However, strong relations were found between emotional dissonance, job satisfaction, intention to quit, and performance. Job satisfaction acted as …

Molecular Dynamics And Time Correlation Function Theories, Russell H. Devane

USF Tampa Graduate Theses and Dissertations

The research presented in this thesis makes use of theoretical/computational techniques to calculate nonlinear spectroscopic signals and molecular volumes. These techniques have become more practical with advances in computational resources and now are an integral part of research in these areas. Preliminary results allude to the power of these techniques when applied to relevant problems and suggest that much progress can be made in understanding the complex nature of nonlinear spectroscopic signals and molecular volume contributions. The nonlinear spectroscopy work involves writing the quantum mechanical response functions in terms of classical time correlation functions which are amenable to calculation using …

Anti-Arab Hate Crimes In The Aftermath Of September 11, 2001: Assessing The Influence Of Geographic And Situational Factors, Ilir Disha

USF Tampa Graduate Theses and Dissertations

This study investigates how hate crimes in general and anti-Arab hate crimes in particular were distributed across different regions of the United States during the 2001- 2002 period. The study explores how a historical event – the terrorist attacks against the U.S. on September 11, 2001 – and county population demographics affect the rates of hate crime against Arabs, Muslims or Middle Easterners. It was hypothesized that antiArab or anti-Muslim hate crimes displaced other forms of hate crime and were characterized by open acts of violence. According to the contact hypothesis, anti-Arab and anti-Muslim hate crimes would be more likely …

The Impact Of Gender-Role Stereotypes And The Sex-Typing Of The Professor Job On Performance Evaluations In Higher Education, Jay M. Dorio

USF Tampa Graduate Theses and Dissertations

The present study examined the influences of gender-role stereotypes, gender-role congruity, and the sex-typing of the professor job on performance evaluations of university educators in actual classroom settings. Participants used the Schein Descriptive Index (Schein, 1973) to define gender-role stereotypes, characteristics of their professor/instructor, and the characteristics of an “Effective Professor.” Participants used a behavior summary scale (BSS) formatted student assessment of instruction to evaluate their professor’s/instructor’s performance after a full semester of class participation.

It was hypothesized that a pro-male bias would exist in the sex-typing of the professor job, and that combined with the gender-role stereotypes of participants …

The Effects First Language Use Phonological Difficulty Perception Foreign Accented Speech, Astrid Zerla Doty

USF Tampa Graduate Theses and Dissertations

Listener perception of accentedness has been shown to be influenced by experience with L2 (measured by length of residence in US). However, frequency of L1 use and degree of phonological difficulty (defined by the number of non-native phonetic features targeted) may provide more insight into the role of experience in the perception of accentedness.

Three groups of listeners (monolingual English and Spanish [L1] speakers divided into two groups of high and low use of English [L2]) rated the accentedness of bilingual speakers who spoke with varying degrees of accentedness. The speakers read sentences adapted from Magan (1998) to include phonological …

Autonomous Optical Measurements In Bayboro Harbor (Saint Petersburg, Florida), Chunzi Du

USF Tampa Graduate Theses and Dissertations

Estimating with precision coastal marine properties such as primary production, particulate and dissolved carbon, and red tide concentrations is a challenging but important part of marine research. It benefits not only the local communities, but also provides an important input to various global biogeochemical modeling efforts. Due to the complexity of coastal environments resulting from temporal variability of tidal and riverine influences, it is useful to develop and deploy an automated sensor network that provides real-time feedback. It can be used to validate remote sensing models to retrieve in-water constituents, and provide calibration and validation for atmospheric correction of satellite …
