Practical Vibration Evaluation And Early Warning Of Damage In Post-Tensioned Tendons, Jaime Lopez-Sabando

USF Tampa Graduate Theses and Dissertations

Severe corrosion damage and even complete failure was recently discovered in external post-tensioned (PT) tendons of three Florida's pre-cast, segmental bridges over seawater. A key deterioration factor was the formation of large bleed water grout voids at or near the anchorages. Steel corrosion may occur at the grout-void interface or in the air space of the void itself. Since the tendons are critical to the structural integrity of the bridges, reliable and non-intrusive damage detection methods are desirable to manage or prevent future occurrences. In recent years several indirect non-destructive methods have been developed or improved to evaluate the conditions …

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. …

Compliant Pediatric Prosthetic Knee, Sebastian Mahler

USF Tampa Graduate Theses and Dissertations

We have designed and examined a compliant knee mechanism that may offer solutions to problems that exist for infants and toddlers who are just learning to walk. Pediatric prosthetic knees on the market today are not well designed for infants and toddlers for various reasons. Children at this age need a prosthetic that is light in weight, durable, and stable during stance. Of the eleven knees on the market for children, all but three are polycentric or four-bar knees, meaning they have multiple points of movement. Polycentric knees are popular designs because they offer the added benefit of stable stance …

Elements Of Narrative Discourse In Selected Short Stories Of Ernest Hemingway, Gueorgui V. Manolov

USF Tampa Graduate Theses and Dissertations

In the "Art of the Short Story" Hemingway elaborates on his concept of omission as it relates not only to prose writing, but to the special case of writing short stories. Hemingway develops two models to describe his short stories: on the one hand, he describes short stories like "The Sea Change" in terms of omission and exclusion, in terms of leaving the story out of the short story, and on the other, he refers metaphorically to "The Snows of Kilimanjaro" as an airplane loaded with story material which would be enough for four novels. Both models suggest a doubling …

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 …

Minimally Innate Ideas, Michele Merritt

USF Tampa Graduate Theses and Dissertations

This project provides a detailed examination and critique of current philosophical, linguistic, and cognitive accounts of first language acquisition. In particular, I focus on the concept of "innate" and how it is embraced, marginally utilized, or abandoned altogether in efforts to describe the way that a child comes to be a competent user of a language. A central question that naturally falls out of this general inquiry is therefore what exactly is supposed to be "innate," according to various theories? Philosophically, the theory of innate ideas put forth to explain human learning has existed for centuries and hence, this thesis …

The Effect Of Optional Real World Application Projects On Mathematics Achievement Among Undergraduate Students, David Milligan

USF Tampa Graduate Theses and Dissertations

Many undergraduate students enrolled in institutions of higher learning wish to connect their learning to real life experiences. By linking reality to academics, students see first hand the practical value in their studies. The purpose of this study was to critically analyze the practice of application projects in undergraduate mathematics courses to determine if, and if so how, students benefit from optional real world application projects. The study was limited to specific courses within a non-math major's undergraduate mathematics program of study at one large research university. Until the appearance of "The Mathematics Umbrella: Modeling and Education" (Grinshpan, 2005), no …

Construction And Application Of Computationally Tractable Theories Of Nonlinear Spectroscopy, Christine L. Neipert

USF Tampa Graduate Theses and Dissertations

Nonlinear optical processes probe systems in unique manners. The signals obtained from nonlinear spectroscopic experiments are often significantly different than more standard linear techniques, and their intricate nature can make it difficult to interpret the experimental results. Given the complexity of many nonlinear lineshapes, it is to the benefit of both the theoretical and experimental communities to have molecularly detailed computationally amenable theories of nonlinear spectroscopy. Development of such theories, bench marked by careful experimental investigations, have the ability to understand the origins of a given spectroscopic lineshape with atomistic resolution. With this goal in mind, this manuscript details the …

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 …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine the attitudes of high school social studies teachers who had English Language Learners (ELL) mainstreamed in their social studies classes. In the school district in which the study took place, approximately 70% (n=240) of the high school social studies teachers had ELL students in their classrooms. For the quantitative portion of the survey, 344 surveys were given to each social studies department chairperson in the county to be completed by all the teachers who currently had ELL students in their social studies classroom. For the qualitative portion of the study, eight high …

Comparison Of Two Treatments For Finger Tip Amputation: A Retrospective Cohort Study, Karen Olson

USF Tampa Graduate Theses and Dissertations

Purpose: To compare the costs and length of disability for conservative treatment versus skin grafting of distal finger and thumb tip amputations. Methods: Thirty-five zone I finger or thumb tip amputations in thirty-five workers in the Southeastern United States were included in this study. Twenty-four were treated with conservative treatment (bandaging to protect the wound). Eleven were treated with skin grafting. The total cost of medical care, total cost including wage replacement, and the length of disability were compared between the two groups. Impairment at the end of treatment was considered. Results: Even when the cost of wage replacement was …

Key Stakeholder Perceptions Of The Expulsion Process For High School Students Identified As Emotionally Disturbed, Suzanne R. O'Neill

USF Tampa Graduate Theses and Dissertations

This study examined how the expulsion process works for seven male ninth grade students identified as emotionally disturbed and in particular, the perceptions students, their parents, five district representatives, and five high school administrators involved in an expulsion have of the process. Furthermore, the study investigated through in-depth interviews possible differences in perceptions between those students who are expelled, parents, and key education personnel involved in expulsion decisions. Computer-based qualitative data analysis software was used to organize and analyze the collected data. Results of the study indicate that the two primary key stakeholder participants; students and their parents, shared predominately …

Two Essays On Market Efficiency ⎯ Tests Of Idiosyncratic Risk: Informed Trading Versus Noise And Arbitrage Risk, And Agency Costs And The Underlying Causes Of Mispricing: Information Asymmetry Versus Conflict Of Interests, Jung Chul Park

USF Tampa Graduate Theses and Dissertations

I examine the informational efficiency of stock markets by testing the relation between idiosyncratic volatility and equity mispricing. I find that the level of mispricing declines with idiosyncratic volatility consistent with the notion that greater levels of firm-specific risk reflect greater participation of informed traders in the market for the stock. However, I also find that mispricing increases with idiosyncratic volatility for highly volatile stocks, and this is attributed to both noise trading and arbitrage risk. In addition, I investigate the link between agency costs and equity mispricing, and whether it exists due to information asymmetry or the degree of …

An Existential-Phenomenological Investigation Of Self-Cutting Among Adolescent Girls, Amanda A. Privé

USF Tampa Graduate Theses and Dissertations

The present study examined the experience of self-cutting, what stops adolescent girls from engaging in self-cutting, and what message adolescent girls who are self-cutting would want to send to other girls taking part in this behavior. Using an existential-phenomenological method of interviewing, adolescent girls were asked a serious of questions in order to gain insight into their thoughts, feelings, and beliefs about the experience of self-cutting. Each interview was tape recorded, transcribed, and thematized. The participants in this study were labeled co-researchers due to the significant role that they had in the completion of this study. The co-researchers consisted of …

Automatic Geo-Referencing By Integrating Camera Vision And Inertial Measurements, Duminda I. B Randeniya

USF Tampa Graduate Theses and Dissertations

Importance of an alternative sensor system to an inertial measurement unit (IMU) is essential for intelligent land navigation systems when the vehicle travels in a GPS deprived environment. The sensor system that has to be used in updating the IMU for a reliable navigation solution has to be a passive sensor system which does not depend on any outside signal. This dissertation presents the results of an effort where position and orientation data from vision and inertial sensors are integrated. Information from a sequence of images captured by a monocular camera attached to a survey vehicle at a maximum frequency …

A 1400-Year Multi-Proxy Record Of Climate Variability From The Northern Gulf Of Mexico, Julie N. Richey

USF Tampa Graduate Theses and Dissertations

A continuous, decadal-scale resolution multi-proxy record of climate variability over the past 1400 years in the northern Gulf of Mexico (GOM) was constructed from a box core recovered in the Pigmy Basin. Proxies include paired analyses of Mg/Ca and oxygen isotopes in the white variety of the planktic foraminifer Globigerinoides ruber and relative abundance variations of G. sacculifer in the foraminifer assemblages. Two multi-decadal intervals of sustained high Mg/Ca values indicate GOM sea-surface temperatures (SSTs) were as warm or warmer than near-modern conditions between 1000 and 1400 yrs BP. Foraminiferal Mg/Ca values during the coolest interval of the Little Ice …

The Impact Of Organizational Climate Variables Of Perceived Organizational Support, Workplace Isolation, And Ethical Climate On Salesperson Psychological And Behavioral Work Outcomes, Robert J. Riggle

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to build and test a model that integrates the marketing, management, and psychological literature with respect to organizational climate variables and their direct and indirect impact on salesperson psychological and behavioral outcomes, as well as one that answers the overarching research question of how organizational climate variables impact salesperson psychological and behavioral work outcomes. Data were collected during the time period from April 2006 until May 2006. Three hundred survey invitations were sent via e-mail to salespeople at three organizations. The participating organizations included a privately owned publishing firm located in the southeastern United …

An Experimental Study Of Pro-Dieting And Anti-Dieting Psychoeducational Messages: Effects On Immediate And Short-Term Psychological Functioning And Weight Control Practices In College Women, Megan Roehrig

USF Tampa Graduate Theses and Dissertations

While dieting is relatively normative in our society, it is controversial within the fields of eating disorders and obesity. Dieting for weight loss has been touted by the obesity prevention field as a solution to the growing obesity epidemic, yet a body of research in the eating disorders field has also implicated it in the etiology and maintenance of eating pathology. Thus, a divergence in approaches toward dieting has emerged, with both prodieting and anti-dieting messages being recommended. Little is known, however, about the impact of these two types of messages on immediate and short-term psychological functioning and weight control …

The Art Of Existentialism: F. Scott Fitzgerald, Ernest Hemingway, Norman Mailer And The American Existential Tradition, J'Aimã© L. Sanders

USF Tampa Graduate Theses and Dissertations

The purpose of my research is to examine the philosophic influences on three literary works: F. Scott Fitzgerald's The Great Gatsby, Ernest Hemingway's Death in the Afternoon, and Norman Mailer's An American Dream. Through an investigation of biographical, historical, cultural, and textual evidence, I will argue for the influence of several European philosophers---Friedrich Nietzsche, Søren Kierkegaard, and Martin Heidegger---on these authors and on the structures and messages of their works. I will discuss how the specific works I have selected not only reveal each author's apt understanding of the existential-philosophical crises facing the individual in the twentieth century, but also …

The Effect Of Thin-Slicing On Structured Interview Decisions, Gregory F. Schmidt

USF Tampa Graduate Theses and Dissertations

This study examined whether hiring recommendations based on thin slices of a structured interview were associated with recommendations based on the interview in its entirety. After viewing 12 seconds of silent interviewee behavior, participants made hiring recommendations that were significantly correlated with those produced by individuals viewing a still-frame of the interview and the entire interview. In an effort to determine what sources of information participants were using to arrive at their recommendations, nonverbal behaviors were examined in detail. Applicants who appeared attentive, not anxious, competent, confident, dominant, optimistic, and professional were more likely to receive positive hiring recommendations than …

The Impact Of Management’S Tone On The Perception Of Management’S Credibility In Forecasting, Robert D. Slater

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to examine the impact of management altering its tone in communications on participants' perceptions of management credibility. Management's tone in communicating with participants was manipulated using communications from management under two treatment conditions. In period one of the study management's tone was manipulated within the management statement on internal controls as required by the Public Company Accounting Oversight Board's (PCAOB) Auditing Standards No. 2. In period one, participants had no knowledge of management's prior forecasting accuracy. Consistent with predicted hypotheses, the findings reveal that management can increase its credibility with participants by communicating its …

Pricing Models And Analysis Of Corporate Coupon-Bonds And Credit Default Swaptions, Michiru Shibata

USF Tampa Graduate Theses and Dissertations

In this work, pricing models of corporate coupon-bonds and credit default swaptions are derivedand analyzed. Corporate coupon-bonds are priced incorporating both intensity models and structural models, and also jumps introduced by seasonal effects. In deriving the models, we form portfolios to hedge the risk incurred by the instruments, then derive PDE equations using the arbitrage principle and the Ito Lemma for jump processes. The mathematical models are the parabolic-type PDE equations with terminal conditions and boundary conditions. These PDE problems are analyzed and solved by various transformations and incorporation with probabilistic properties. Either a unique solution in the exponential form …

Construct Validity Of Situational Judgment Tests: An Examination Of The Effects Of Agreeableness, Organizational Leadership Culture, And Experience On Sjt Responses, Jonathan Adam Shoemaker

USF Tampa Graduate Theses and Dissertations

Numerous factors are likely to influence response patterns to situational judgment tests, including agreeableness, leadership style, impression management, and job and organizational experience. This research presents background information and research on situational judgment tests and several constructs hypothesized to influence situational judgment test responses. A situational judgment test and manipulations to influence response patterns were developed and piloted with a small sample of management professionals and undergraduate students. Larger samples of management professionals and undergraduate students participated in the experimental research. Participants were asked to imagine that they are applying for a job. Each participant was presented with background information …

"A Woman's Face, Or Worse": Otto Rank And The Modernist Identity, Michael L. Shuman

USF Tampa Graduate Theses and Dissertations

Otto Rank is a significant but generally overlooked figure in the early history of psychoanalysis, and his work provides an illuminating context for the study of subjectivity and modernist culture. The "modernist identity" of my title is intended to represent, first, the concept of the individual self identified and expressed during this period and, secondly, the unique identity of modernist culture developed by artists through creative acts and emanating as the intellectual ambiance of the era. Through an examination of Rank's later theories and the work of prominent modernist artists, including Lawrence, Yeats, and Eliot, this dissertation will show that …

Psychometric Functions Of Clear And Conversational Speech For Young Normal Hearing Listeners In Noise, Jane Smart

USF Tampa Graduate Theses and Dissertations

Clear speech is a form of communication that talkers naturally use when speaking in difficult listening conditions or with a person who has a hearing loss. Clear speech, on average, provides listeners with hearing impairments an intelligibility benefit of 17 percentage points (Picheny, Durlach, & Braida, 1985) over conversational speech. In addition, it provides increased intelligibility in various listening conditions (Krause & Braida, 2003, among others), with different stimuli (Bradlow & Bent, 2002; Gagne, Rochette, & Charest, 2002; Helfer, 1997, among others) and across listener populations (Bradlow, Kraus, & Hayes, 2003, among others). Recently, researchers have attempted to compare their …

Greater Flexibility, Greater Growth: A Comparative Study Of Labor And Capitalist Models In Japan, Germany And The United States, Jay Arthur Thompson

USF Tampa Graduate Theses and Dissertations

After the end of the Second World War, three major economic powers emerged. Japan in Asia, Germany in Europe, and the United States in North America, quickly became the economic engines of their respective regions. Japan, with its "catch-up" and producer centered economy, grew so fast and so large, that there were worries in America that the Japanese would end up winning the economic war. West Germany, supported by the capitalist world, became a miracle economy, and the economic power of the European Union. In the past fifteen years however, these two economies have faltered and stagnated. In Japan, the …

Sensitivity Analysis Of The Transit Boardings Estimation And Simulation Tool (Tbest) Model, Dajana Vuckovic

USF Tampa Graduate Theses and Dissertations

Public transportation, although modest in the United States carrying about 2 percent trips, still serves millions of people as the main and only means of transportation. Recently released data set by Census, the 2006 American Community Survey (ACS) shows the main mode of travel for work commute is not surprisingly the automobile with over 86 percent and public transportation with nearly 5 percent users. Transit agencies strive to provide effective, convenient, and desirable transport. Because of the constant changes in our environment, being able to predict the response of riders to different network or system changes is extremely useful. Ridership …

Local Strategies In A Global Network: Disability Rights Advocacy In Jamaica, Joan A. Tucker

USF Tampa Graduate Theses and Dissertations

The declaration of the International Year of Disabled Persons in 1981 and the international activism of persons with disabilities resulted in the globalization of disability, which involved a new framework for the treatment of PWDs. Although disability activism was being played out globally, it has been about PWDs gaining equality and full participation in their local societies. Therefore, at the heart of an international movement was the strategic organization of PWDs, most of who live in the developing world. This dissertation is based on a case study of activism for disability rights in one particular developing society, Jamaica. The Jamaican …

Uncertainty In The Information Supply Chain: Integrating Multiple Health Care Data Sources, Monica Chiarini Tremblay

USF Tampa Graduate Theses and Dissertations

Similar to a product supply chain, an information supply chain is a dynamic environment where networks of information-sharing agents gather data from many sources and utilize the same data for different tasks. Unfortunately, raw data arriving from a variety of sources are often plagued by errors (Ballou et al. 1998), which can lead to poor decision making. Supporting decision making in this challenging environment demands a proactive approach to data quality management, since the decision maker has no control over these data sources (Shankaranarayan et al. 2003). This is true in health care, and in particular in health planning, where …
