Exploring The Relationship Of Emotional Intelligence To Transformational Leadership Within Mentoring Relationships, Shannon Webb

USF Tampa Graduate Theses and Dissertations

The present study examines the extent to which emotional intelligence is related to transformational leadership within mentoring relationships. One hundred and twelve faculty members responsible for mentoring doctoral students completed the Schutte Self Report Inventory of Emotional intelligence, as well as measures of empathy, self awareness, and self confidence. Transformational leadership ratings for each professor were provided by the doctoral student(s) who were advised by him or her. Study results indicate that emotional intelligence can predict several aspects of transformational leadership, including charisma and inspirational motivation. The predictive power of emotional intelligence was, in several cases, explained by the personality …

Shakespeare’S Midsummer Fairies: Shadows And Shamen Of The Forest, Patricia, Roy

USF Tampa Graduate Theses and Dissertations

Recent interest in environmental crises has inspired literary critics to consider how the history of ideas shapes our current ecological debates. Shakespeare's A Midsummer Night's Dream sets the stage for assessing how Renaissance attitudes towards nature have influenced current ideologies. While the play appears to be a fantasy, it reveals a relationship with nature, both physically and figuratively. The play's excursion into the woods shows an attempt to heal human relationships. Shakespeare's use of the imagery of nature argues in favor of the green world, for it is a world inhabited by shadows and shamen -- or, as Shakespeare calls …

Investigation Of Spatial Filtering For Planar Range-Resolved Pulsed Laser Ablated Plume Imaging, James F. Winslow

USF Tampa Graduate Theses and Dissertations

This thesis presents a study of the intensified charge-coupled device (ICCD) imaging of pulsed laser ablated plumes. Two-dimensional imaging of laser ablated plumes is a very important diagnostic for PLD. ICCD array photography is a useful tool for imaging PLD. The images obtained using the standard technique are characterized and compared with ICCD images of an altered plume, ICCD images intentionally violating standard imaging procedures, and film thickness. The depth resolving properties of a pinhole was investigated with the intention of applying it to PLD plume imaging. This results in a more thorough understanding of the depth resolving property of …

Race, Religion, And Attitudes Toward Capital Punishment: A Test Of Attribution Theory, Sheila M. Schlaupitz

USF Tampa Graduate Theses and Dissertations

The present study attempts to provide a more thorough understanding of public attitudes toward capital punishment. Two theories are tested toward this end, utilizing a random sample taken from the jury pool in Hillsborough County, Florida.

First, An indirect test of reference group theory demonstrates the degree to which faith group, religiosity, and race affect public attitudes toward the death penalty. Surprisingly, there is little, albeit mixed, support for reference group theory as it attempts to explain attitudes toward capital punishment. Using the relationships between religion and capital punishment attitudes that we presumed would emerge from the test of reference …

USF Tampa Graduate Theses and Dissertations

This research attempts to provide an explanation for the firm's choice of using either a dividend or a stock repurchase for distributing cash to its stockholders. It also provides an examination of the impact of the firm's disbursement decision on the stock market's resulting reassessment of the value of the firm.

Before analyzing the disbursement decision, I examine the stock market effects of dividends and stock repurchases using an event study methodology that corrects for the possible variance change effects of cash distribution announcements. I find that the measured wealth effects are statistically significant and similar, for the most part, …

Mediating The Model: Women's Microenterprise And Microcredit In Tobago, West Indies, Cheryl A. Levine

USF Tampa Graduate Theses and Dissertations

From the perspectives of economic anthropology, feminist anthropology, and feminist theory, this applied anthropological study is an evaluation of a popular international development model targeting poor women. Based on the celebrated Grameen Bank of Bangladesh, the so-called "microcredit" model is designed as a poverty alleviation strategy to provide small loans to poor women in rural settings and is designed to facilitate microenterprise development. Due to the popularity of the microcredit model with the international development community, it is being replicated in different settings. Through an analysis of microenterprise development among Afro-Caribbean women, this study presents the argument that successful application …

The Relationship Between Optokinetic Nystagmus And Caloric Weakness, D'Arcy D. Cyr

USF Tampa Graduate Theses and Dissertations

Traditionally, results from caloric testing and optokinetic nystagmus (OKN) testing are analyzed separately because caloric testing is a measure of peripheral function and OKN testing is considered to be a measure of central function. However, there is a connection between the visual system and the vestibular system in the vestibular nucleus of the brainstem. The purpose of this paper was to determine whether a relationship exists between optokinetic nystagmus results and unilateral caloric weakness results. This was determined by conducting a retrospective study of forty patients who exhibited a unilateral caloric weakness greater than or equal to twenty percent and …

Film In The Classroom: Toward A More Effective Pedagogy, Jonathan Godwin

USF Tampa Graduate Theses and Dissertations

The postmodern critique has effectively called on anthropologists to reevaluate ethnographic authority when representing others. However, what is often found lacking in this criticism is an exploration of the ways in which audiences interpret anthropological knowledge. One crucial area that can be easily researched is audience reception of film in introductory anthropology classes. As professors of anthropology increasingly rely on film for illustrating anthropological concepts, we must have an understanding of how this medium is interpreted by student audiences. Film's ability to convey complex information without additional contextualization has yet to be substantiated and previous research has indicated that visual …

Frequency Distributions Of Escherichia Coli Subtypes In Various Fecal Sources Over Time And Geographical Space: Application To Bacterial Source Tracking Methods, Matthew A. Anderson

USF Tampa Graduate Theses and Dissertations

Bacterial source tracking (BST) methods often involve the use of phenotypic or genotypic fingerprinting techniques to compare indicator bacteria such as Escherichia coli isolated from unknown sources against a library of fingerprints from indicator bacteria found in the feces of various known source animals. The predictive capability of a library is based in part on how well the library isolates reflect the true population diversity of indicator bacteria that can potentially impact a water body. The purpose of this study was to compare the behavior of E. coli population structures in the feces of humans, beef cattle and horses across …

Optimizing Long-Term Retention Of Abstract Learning, Danielle Mazur

USF Tampa Graduate Theses and Dissertations

In a distributed learning strategy, study time is spread across multiple study sessions, without increasing total study time. The benefits of distributed practice, also known as spaced practice, on learning of rote-memory tasks (e.g., spelling, addition, and cued-recall of word pairs) are well known. However, few researchers have looked at the effects of distributed practice on the learning of abstract materials (e.g., physics problems, logical deductions, and algebra). We examined the effects of distributed practice on learning the abstract task of matrix multiplication. In Experiment 1, we taught participants matrix multiplication in either a massed (i.e., 0-day interstudy gap), or …

Otherness And Blackness, Chioke A. M I'Anson

USF Tampa Graduate Theses and Dissertations

The purpose of this paper is to provide a phenomenological examination of Otherness as it relates to the experience of being black in the America. The project begins with a summary of the Otherness theories of Emmanuel Levinas, Jean-Paul Sartre, and Simone de Beauvoir. I then compare these accounts to "Black Consciousness" with a criticism of Sartre from Frantz Fanon. I use this criticism to construct new concepts that will help to better understand the experience of blackness.

Towards A Single-Mode Dispensed Polymer Optical Waveguide, Jill Michelle Kalajian

USF Tampa Graduate Theses and Dissertations

Dispensed organic polymer optical waveguides suitable for single-mode operation were recently fabricated. Different dispensing pressures, polymers, and dispensing tips were used in the drawing method.

The waveguides were measured to be approximately 16[mu] wide and 0.8[mu] tall. This is significantly smaller than previously reported dimensions of 300[mu] x 3.5[mu] waveguides fabricated with a similar dispensed polymer method. The waveguides were also found to be suitable for single-mode operation through a series of approximate calculations . This is also something previously not achieved with the larger waveguides.

This novel approach to waveguide fabrication could reduce the expense and time of creating …

Psychological Factors Associated With Skin Cancer Detection Behaviors In Individuals With A Family History Of Melanoma, Lora M. Azzarello

USF Tampa Graduate Theses and Dissertations

Current ACS guidelines recommend routine screening for cancer (ACS, 2002). Motivation to adhere to guidelines may be different for individuals with and without a family history of melanoma (Jonna, et al., 1998). Prior research examining the relationship between family history and skin cancer detection behaviors (Berwick et al., 1996; Friedman et al., 1993; Oliveria et al., 1999) have failed to utilize a theoretical framework to derive hypotheses. The purpose of the present study was to examine the utility of Protection Motivation Theory (PMT) in explaining intentions to engage in skin cancer screening (SCS) and skin self-examination (SSE). In addition, the …

Scheduling Of 2-Operation Jobs On A Single Machine To Minimize The Number Of Tardy Jobs, Radhika M. Yeleswarapu

USF Tampa Graduate Theses and Dissertations

This study focuses on the study of a unique but commonly occurring manufacturing problem of scheduling of customized jobs consisting of two operations on a single multi-purpose machine with the performance objective of minimizing the number of tardy jobs (jobs that are not completed by their due dates). Each customized job to be complete needs one unique operation and one common operation performed on it. We considered a static case in this work. The objective of minimizing the number of tardy jobs is considered where all jobs have equal weights and the maximum tardiness has no effect on the performance. …

Self-Interference Handling In Ofdm Based Wireless Communication Systems, Tevfik Yücek

USF Tampa Graduate Theses and Dissertations

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation scheme that provides efficient bandwidth utilization and robustness against time dispersive channels. This thesis deals with self-interference, or the corruption of desired signal by itself, in OFDM systems. Inter-symbol Interference (ISI) and Inter-carrier Interference (ICI) are two types of self-interference in OFDM systems. Cyclic prefix is one method to prevent the ISI which is the interference of the echoes of a transmitted signal with the original transmitted signal. The length of cyclic prefix required to remove ISI depends on the channel conditions, and usually it is chosen according to the worst …

Using The Ablls With English Language Learners: Implications For Students And Teachers, Lorie G. Schultz

USF Tampa Graduate Theses and Dissertations

English language learners are traditionally behind in academics such as reading, math and science. Hispanics, who make up the vast majority of English language learners, tend to not enroll in pre-school or higher education, have higher dropout rates and as adults earn less than whites. Common instructional strategies used in public schools are not meeting the needs of these students. The field of TESOL (Teachers of English to Speakers of Other Languages) has typically offered a wide variety of poorly defined teaching strategies that are not based on empirical research. Within public schools, assessment tends to serve the purpose of …

The Fleeting Effects Of Retrieval Cue Attributes In The Pier2 Memory Model, Amie L. Wilbanks

USF Tampa Graduate Theses and Dissertations

Processing Implicit and Explicit Representations (PIER2) is a model of memory that makes predictions about memory performance based on the interaction of known and newly acquired information by studying how implicitly activated associates affect episodic memory. Nelson and Zhang (2000) found a significant effect of cue connectivity in a multiple regression analysis of the variables known to affect cued recall, but at that time no manipulational experiments had studied the cue connectivity effect in the laboratory. The present paper presents a series of three experiments designed to investigate the effect of cue connectivity in the context of the PIER2 memory …

The characterization of fine particles is an area of immense significance to many industrial endeavors. It has been estimated that 70% of all industrial processes deal with fine particles at some point in the process. A natural phenomenon occurring in these processes is colloidal aggregation. This study examines aggregation in colloidal systems in order to characterize, examine, and control this occurrence in industrial processes. The study of particle aggregation has been broken into many different areas, such as collision mechanisms, interaction energy etc, but a complete model that integrates these different aspects has never been fully realized. A new model …

Three Dimensional Finite Element Model For Lesion Correspondence In Breast Imaging, Yan Qiu

USF Tampa Graduate Theses and Dissertations

Predicting breast tissue deformation is of great significance in several medical applications such as surgery, biopsy and imaging. In breast surgery, surgeons are often concerned with a specific portion of the breast, e.g., tumor, which must be located accurately beforehand. Also clinically it is important for combining the information provided by images from several modalities or at different times, for the planning and guidance of interventions. Multi-modality imaging of the breast obtained by mammography, MRI and PET is thought to be best achieved through some form of data fusion technique. However, images taken by these various techniques are often obtained …
