Pipe Dreams And Primitivism: Eugene O'Neill And The Rhetoric Of Ethnicity, Donald P. Gagnon

USF Tampa Graduate Theses and Dissertations

Eugene O'Neill included within his vision of humanity a series of complex, emotionally and psychologically developed black characters. Despite critical controversy over his methods or effectiveness, from his eerily silent mulatto in "Thirst" through the grandiose incarnation of The Emperor Jones and the everyman of Joe Mott and The Iceman Cometh, O'Neill created characters of African descent that thrilled and infuriated critics and audiences alike.

A closer exploration of the issues involved in his portrayal of ethnically identified characters seems necessary, an exploration that does not limit itself to an interrogation of ethnicity per se in O'Neill's plays, but …

A Distributed Routing Algorithm For Er-Lsp Setup In Mlps Networks, Naga Siddhardha Garige

USF Tampa Graduate Theses and Dissertations

The rapid growth of the Internet, in the last few years, has generated a need to enhance the existing IP networks in the areas of availability, dependability and scalability in order to provide a mission critical networking environment. In contemporary IP networks, data packets are routed as a function of the destination address and a single metric such as hop-count or delay. This approach tends to cause message traffic to converge onto the same link, which significantly increases congestion and leads to unbalanced network resource utilization. One solution to this problem is provided by Traffic Engineering (TE), which uses, bandwidth …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine how to best motivate smokers with schizophrenia or schizoaffective disorder to seek treatment for tobacco dependence. Smokers with schizophrenia or schizoaffective disorder (N=78) were randomly assigned to receive a Motivational Interviewing, Psychoeducational, or Minimal Control intervention. A greater proportion of participants receiving the Motivational Interviewing intervention followed through on a referral for tobacco dependence treatment within one-week and one-month post-intervention. Mixed model Analyses of Variance found no differences between groups at one-week or at one-month with respect to tobacco use or motivation to quit. Within group analyses indicated that participants in the …

Computerized Measurement Of Psychological Vital Signs In A Clinical Setting, Ryan K. Russon

USF Tampa Graduate Theses and Dissertations

Due to the increasing demands of third-party payers to show measurable results in a decreased amount of time, mental health practitioners need new tools and techniques to quickly and efficiently assess their client's current status and progress in treatment. The goal of this study was to develop and validate a brief computerized measure of emotional states and personality traits for use as an assessment tool in a clinical setting. Adapted from the State-Trait Personality Inventory (STPI; Spielberger, 1998), the computerized instrument measured state and trait anxiety, anger, depression, and curiosity. The computerized STPI was examined for equivalence with the traditional …

An Investigation Of Bga Electronic Packaging Moiré Interferometry, Norman Rivers

USF Tampa Graduate Theses and Dissertations

As technology progresses towards smaller electronic packages, thermo-mechanical considerations pose a challenge to package designers. One area of difficulty is the ability to predict the fatigue life of the solder connections. To do this one must be able to accurately model the thermo-mechanical performance of the electronic package. As the solder ball size decreases, it becomes difficult to determine the performance of the package with traditional methods such as the use of strain gages. This is due to the fact that strain gages become limited in size and resolution and lack the ability to measure discreet strain fields as the …

Attention-Deficit/Hyperactivity Disorder: General Education Elementary School Teachers' Knowledge, Training, And Ratings Of Acceptability Of Interventions, Stacey Small M.A.

USF Tampa Graduate Theses and Dissertations

Given that researchers estimate approximately one child in every classroom has Attention-Deficit/Hyperactivity Disorder (ADHD), and that most of these students are served in the general education classroom, it is imperative that general education teachers know how to effectively teach these students. Seventy-two general education elementary school teachers completed a survey containing demographic information, a knowledge of ADHD questionnaire, and a survey on interventions for students with ADHD. Results indicated that teachers scored an average of 57% correct on the Knowledge of Attention Deficit Disorders Scale (KADDS), scoring statistically significantly higher on the Symptoms/Diagnosis subscale compared to the General and Treatment …

The Role Of Individual Differences In Learning Alcohol Expectancy Associations, Howard R. Steinberg

USF Tampa Graduate Theses and Dissertations

Alcohol expectancy theory suggests that genetically influenced personality characteristics may lead to differential acquisition of expectancy information, and that this information then may serve as one mediational pathway for alcoholism risk. Research has already shown that expectancy information can predict and even mediate risk, but it has yet to be shown that personality traits can influence the acquisition of alcohol expectancy information. To that end, personality characteristics known to be risk factors for the development of excessive alcohol use were assessed in 83 male undergraduates. In addition, each participant studied, in a paired-associate learning/cued-recall test paradigm, a list of word …

Dwellness: A Radical Notion Of Wilderness, Martin J. Wortman

USF Tampa Graduate Theses and Dissertations

The contemporary concept of wilderness, which is central to environmental theory and activism, is both a help and a hindrance to government policy and to popular environmental beliefs. The Judeo-Christian religious tradition and Locke's property theory provides much of the western cultural and historical basis of humans' environmental attitudes that basically engender exploitation. I argue that a more precise interpretation of Genesis and of Locke reveals that both sources actually promote environmental stewardship while decrying ecological abuse. Next I analyze the history and shortcomings of various wilderness concepts. These shortcomings are all forms of an exclusionist mentality and result in …

Effects Of Bilingualism, Noise, And Reverberation On Speech Perception By Listeners With Normal Hearing, Dashielle M. Febo

USF Tampa Graduate Theses and Dissertations

The accurate perception of spoken English is influenced by many variables, including the listener's native language, reverberation, and background noise. Few studies of speech perception by bilingual listeners have carefully controlled for second language proficiency and even fewer have presented speech in everyday listening environments that contain noise and reverberation. In the present study, detailed language background, language proficiency information, and individual language samples were collected and the speech stimuli were presented in a variety of quiet, noisy, and reverberant listening environments.

The effects of noise and reverberation on the perception of American English monosyllabic words was examined for two …

Scavenger: A Junk Mail Classification Program, Rohan V. Malkhare

USF Tampa Graduate Theses and Dissertations

The problem of junk mail, also called spam, has reached epic proportions and various efforts are underway to fight spam. Junk mail classification using machine learning techniques is a key method to fight spam. We have devised a machine learning algorithm where features are created from individual sentences in the subject and body of a message by forming all possible word-pairings from a sentence. Weights are assigned to the features based on the strength of their predictive capabilities for spam/legitimate determination. The predictive capabilities are estimated by the frequency of occurrence of the feature in spam/legitimate collections as well as …

Choral Music Education: A Survey Of Research 1996-2002, Amber Turcott

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to review and summarize selected choral music education research published between 1996-2002. Four major research surveys in this area were previously published by Gonzo (1973), Hylton (1983), Phillips (1992), and Grant and Norris (1998). Each of these authors stressed a need for research in all areas of choral music education beyond the dissertation level and called for research that mimicked "real-world" experiences that would benefit choral music educators.

This study investigated the following: (a) whether research studies in choral music education have increased beyond doctoral dissertation studies; (b) whether previous research studies have been …

Performance Verification Of Personal Aerosol Sampling Devices, Steven T. Luecke

USF Tampa Graduate Theses and Dissertations

International standards establish criteria for size-selective aerosol sampling for industrial hygiene. Commercially available aerosol samplers are designed to conform to these criteria. This study uses semi-monodispersed aerosols generated in a vertically aligned test chamber to compare the performance of three commercially available respirable dust samplers, one of which can simultaneously sample for thoracic and inhalable dust fractions. Comparison methods are used to calculate a theoretical fractional value based on the appropriate sampling conventions of the total dust concentration and size distribution of test materials. Performance of actual samplers can be conducted by comparing observed results to the theoretical value. Results …

Body Image As A Function Of Colorism: Testing A Theoretical Model, Alicia V. Hall

USF Tampa Graduate Theses and Dissertations

A Covariate Structure Model was used to examine a possible relationship between colorism as a component of body image and global psychological functioning in the hypothesized model. Two hundred-fifty-five African-American women were recruited from undergraduate psychology and social work classes to participate in the current study from state and community colleges in the southeastern United States, and from social groups and church organizations. The results indicated that the hypothesized model was not a good fit to the data; therefore, the model was re-evaluated. The results of the analysis of the revised model indicated that the revised model was not plausible. …

Evaluation And Implementation Of A Molecular-Based Protocol For The Identification Of Enteroviruses At The Florida Department Of Health – Tampa Laboratory, Matthew Adams Smith

USF Tampa Graduate Theses and Dissertations

The Enterovirus genus within the family Picornaviridae contains over 100 serotypes, of which sixty-four are known to be human pathogens. Infection with this group of RNA viruses produces a myriad of clinical conditions including poliomyelitis, meningitis, encephalitis, respiratory illnesses, and hand-foot-and-mouth disease. Outbreaks have been documented worldwide; significant morbidity and mortality exist to warrant laboratory surveillance.

Traditionally, enteroviruses have been identified to the level of serotype by the serum neutralization assay. However, numerous problems are associated with this assay. The serum neutralization assay is labor intensive, results are often ambiguous, and reagents are becoming difficult to obtain. Recently, molecular-based typing …

Deep Ecology And Heideggerian Phenomenology, Matthew Antolick

USF Tampa Graduate Theses and Dissertations

This thesis examines the connections between Arne Naess's Deep Ecology and Martin Heidegger's Phenomenology. The latter provides a philosophical basis for the former. Martin Heidegger's critique of traditional metaphysics and his call for an "event" ontology that is deeper than the traditional substance ontology opens a philosophical space in which a different conception of what it is to be emerges. Heidegger's view of humans also provides a basis for the wider and deeper conception of self Arne Naess seeks: one that gets rid of the presupposition that human beings are isolated subjects embedded in a framework of objects distinct from …

Informed Consent: Its Origin, Purpose, Problems, And Limits, Nancy M. Kettle

USF Tampa Graduate Theses and Dissertations

The doctrine of informed consent, defined as respect for autonomy, is the tool used to govern the relationship between physicians and patients. Its framework relies on rights and duties that mark these relationships. The main purpose of informed consent is to promote human rights and dignity. Some researchers claim that informed consent has successfully replaced patients' historical predispositions to accept physicians' advice without much explicit resistance.

Although the doctrine of informed consent promotes ideals worth pursuing, a successful implementation of these ideals in practice has yet to occur. What has happened in practice is that attorneys, physicians, and hospital administrators …

Effect Of Presentation Modality On Predictions Of Children’S Communication Ability In The Classroom, Mary Aguila

USF Tampa Graduate Theses and Dissertations

The modified Goodman scale, a hearing loss classification scale, is commonly used to describe audiometric findings for both children and adults (Haggard & Primus, 1999). This scale uses one or two word descriptors for hearing level categories and is based on a pure tone average (PTA), the average of hearing thresholds at 500, 1000, and 2000 Hz. Although these categories were developed from clinical and educational observations (Goodman, 1965), degree of hearing loss has not been shown to reliably predict the educational or language performance of children with hearing impairment (Martin & Clark, 1996). This study was designed to evaluate …

Selection Of Clinical Trials: Knowledge Representation And Acquisition, Savvas Nikiforou

USF Tampa Graduate Theses and Dissertations

When medical researchers test a new treatment procedure, they recruit patients with appropriate health problems and medical histories. An experiment with a new procedure is called a clinical trial. The selection of patients for clinical trials has traditionally been a labor-intensive task, which involves matching of medical records with a list of eligibility criteria.

A recent project at the University of South Florida has been aimed at the automation of this task. The project has involved the development of an expert system that selects matching clinical trials for each patient. If a patient's data are not sufficient for choosing …

The Effects Of Induced Depressed Mood On Recall Of Experiences With Racial Discrimination, Tamra Williams

USF Tampa Graduate Theses and Dissertations

Two studies examined the relationship between reported racial discrimination and depression, and whether this relationship may be due to depressed mood induced influences. In study 1, sixty-four African American undergraduates completed measures of current depression, a racial discrimination index, and rated vignettes that were ambiguous in terms of the presence or absence of racial discrimination. A significant correlation was found between depression and reported racial discrimination. The purpose of Study 2 was to examine the effect of mood on recall of past experiences with discrimination. Groups of subjects were randomly assigned to either a sad mood induction condition or a …

Computerized Dynamic Visual Acuity With Volitional Head Movement In Patients With Vestibular Dysfunction, Erika L. Johnson

USF Tampa Graduate Theses and Dissertations

Patients with non-compensated vestibular dysfunction frequently complain of the ability to maintain dynamic visual acuity during activities which require the movement of the head. When this occurs the patient is experiencing oscillopsia, which is the symptom resulting from a non-functional vestibulo-ocular reflex (VOR). To measure the presence of oscillopsia, tests of dynamic visual acuity (DVA) may be used.

A recent test of DVA has been reported which is administered while patients are walking on a treadmill. Although this test has been shown to be useful in evaluating DVA in patients, there are several disadvantages to treadmill use. These include physical …

Development Of An Aural Rehabilitation Cd-Rom, Sierra Macdonald

USF Tampa Graduate Theses and Dissertations

A need has been established for aural rehabilitation (AR) sessions throughout the years. The literature reviewed here demonstrates that new hearing aid users do benefit from a structured follow-up AR program. However, this need is often not met for a variety of patient and audiologist related factors. Therefore, an AR program that could be viewed at home has been suggested. I have developed a prototype for a CD-ROM based aural rehabilitation (AR) program. Included in the program are communication and speechreading strategies, which are the most prevalent materials in AR. The instructional and interaction portions of the prototype were created …

An Examination Of The Relationship Between The U-Titer Ii And Hearing Aid Benefit, Maura Koenig Kenworthy

USF Tampa Graduate Theses and Dissertations

The aim of this study was to measure the effects of audiologic intervention on self-perceived quality of life in the elderly hearing-impaired population. The tested hypothesis was that hearing aid use would result in improved quality of life as measured by utilities. In this study, utilities were obtained using the U-Titer II, an interactive software program designed to measure an individual's health state preference or utility. This study also examined the issue of numeracy, which is described as an understanding of basic probability, and its effect with an individual's ability to accurately complete utilities.

Data from 54 individuals …

Regulation Of Yy1, A Multifunctional Transcription Factor, Ya-Li Yao

USF Tampa Graduate Theses and Dissertations

Yin Yang 1 (YY1) is a sequence-specific DNA binding transcription factor that plays an important role in development and differentiation. It activates or represses many genes during cell growth and differentiation and is also required for the normal development of the mammalian embryo. Moreover, it has been shown that YY1 may function as a transcriptional initiator. In this dissertation, regulation of human YY1 is analyzed systematically at three levels: At the genomic level, one major transcriptional initiation site of the YY1 gene was mapped to 478 bp upstream of the ATG translational start site. The YY1 promoter was localized to …

Response Of The Threatened Sand Skink (Neoseps Reynolds!) And Other Herpetofaunal Species To Burning And Clearcutting In The Florida Sand Pine Scrub Habitat, Kristie D. Gianopulos

USF Tampa Graduate Theses and Dissertations

Florida scrub habitat is a naturally fire maintained habitat that is highly endangered because of great demand for land for agriculture and real estate. Maintenance of remaining patches ofFlorida scrub habitat requires active management. We experimentally investigated the effects of clearcutting and burning on sand skink populations in three patches of sand pine scrub. Each patch included a clearcut plot, a burned plot, and an undisturbed plot. Treatment plot boundaries were drawn in 1995 such that each plot was no different from any other plot in sand skink densities. The responses of sand skink and other herpetofauna populations were monitored …
