Growth Of 3c-Sic On (111)Si Using Hot-Wall Chemical Vapor Deposition, Christopher Locke

USF Tampa Graduate Theses and Dissertations

The heteroepitaxial growth of cubic silicon carbide (3C-SiC) on (111) silicon (Si) substrates, via a horizontal hot-wall chemical vapor deposition (CVD) reactor, has been achieved. Growth was conducted using a two step process: first the Si substrate surface is converted to SiC via a carbonization process and second the growth of 3C-SiC is performed on the initial carbonized layer. During carbonization, the surface of the Si is converted to 3C-SiC, which helps to minimize the stress in the growing crystal. Propane (C3H8) and silane (SiH4), diluted in hydrogen (H2), were used as the carbon and silicon source, respectively. A deposition …

Program Monitoring In A Mandatory-Results Model, Srikar Reddy Reddy

USF Tampa Graduate Theses and Dissertations

In many real enforcement systems, a security-relevant action must return a result before the application program that invoked that action can continue to execute. However, current models of runtime mechanisms do not capture this requirement on results being returned to application programs; current models are limited to reasoning about policies and enforcement in terms of actions alone, without considering the results of those actions. This thesis presents a more general model of runtime policy enforcement in which all actions return (possibly void- or unit-type) results. This mandatory-results model more accurately reflects the capabilities and limitations of real enforcement mechanisms, particularly …

Nanostructure Morphology Variation Modeling And Estimation For Nanomanufacturing Process Yield Improvement, Gang Liu

USF Tampa Graduate Theses and Dissertations

Nanomanufacturing is critical to the future growth of U.S. manufacturing. Yet the process yield of current nanodevices is typically 10% or less. Particularly in nanomaterials growth, there may exist large variability across the sites on a substrate, which could lead to variability in properties. Essential to the reduction of variability is to mathematically describe the spatial variation of nanostructure. This research therefore aims at a method of modeling and estimating nanostructure morphology variation for process yield improvement. This method consists of (1) morphology variation modeling based on Gaussian Markov random field (GMRF) theory, and (2) maximum likelihood estimation (MLE) of …

Loyalty Of Online Faculty: A Work Design Perspective Of The Impact Of A Telecommuting Work Environment On Employee Loyalty, Kenneth N. Pereira

USF Tampa Graduate Theses and Dissertations

ABSTRACT This study empirically evaluates the theoretical impact of a telecommuting or online work environment on employee loyalty. While the concept of employee loyalty has been extensively researched, the concept of the impact of the work environment on employee loyalty is fairly new. Specifically, this study operationally defines the work environment characteristics that contribute to employee loyalty and examines the impact of the online or telecommuting work environment on employee loyalty. A survey instrument is utilized to collect perceptual data about the psychological components of the work environment and their impact on employee loyalty from the employee's perspective. Multiple linear …

The Influence Of Parental Support On Antisocial Behavior Among Sixth Through Eleventh Graders, José Ordóñez

USF Tampa Graduate Theses and Dissertations

The primary objective of this study was to explore the influence of parental support on antisocial behavior among 1514 adolescents from Sarasota County (Florida). An integrated multilevel approach was developed considering elements of the social support paradigm and social learning theory. Using Hierarchical Linear Modeling (HLM), the results suggest that both paternal and maternal support were significant factors in the prevention of antisocial behavior. However, paternal support demonstrated to be stronger when students justified school misbehavior. At the school level, the findings suggest that the influence of parental support to reduce antisocial behavior competes with favorable definitions toward crime learned …

Generation Capacity Expansion In Restructured Energy Markets, Vishnuteja Nanduri

USF Tampa Graduate Theses and Dissertations

With a significant number of states in the U.S. and countries around the world trading electricity in restructured markets, a sizeable proportion of capacity expansion in the future will have to take place in market-based environments. However, since a majority of the literature on capacity expansion is focused on regulated market structures, there is a critical need for comprehensive capacity expansion models targeting restructured markets. In this research, we develop a two-level game-theoretic model, and a novel solution algorithm that incorporates risk due to volatilities in profit (via CVaR), to obtain multi-period, multi-player capacity expansion plans. To solve the matrix …

Temporal Registration Of Mammograms By Finite Element Simulation Of Mr Breast Volume Deformation, Yan Qiu

USF Tampa Graduate Theses and Dissertations

Clinically it is important to combine information provided by mammographic images from multiple views or at different times. Taking regular mammographic screening and comparing corresponding mammograms are necessary for early detection of breast cancer, which is the key to successful treatment. However, mammograms taken at different times are often obtained under different compressions, orientations or body positions. A temporal pair of mammograms may vary quite significantly due to the spatial disparities caused by the variety in acquisition environments, including the 3D position of the breast, the amount of the pressure applied, etc. Such disparities can be corrected through the process …

A Framework For Resource Assignments In Skill-Based Environments, Luis Daniel Otero

USF Tampa Graduate Theses and Dissertations

The development of effective personnel assignment methodologies has been the focus of research to academicians and practitioners for many years. The common theory among researchers is that improvements to the effectiveness of personnel assignment decisions are directly associated with favorable outcomes to organizations. Today, companies continue to struggle to develop high quality products in a timely fashion. This elevates the necessity to further explore and improve the decision-making science of personnel assignments. The central goal of this research is to develop a novel framework for human resource assignments in skill-based environments. An extensive literature review resulted in the identification of …

Power-Control Theory: An Examination Of Private And Public Patriarchy, Jessica Nicole Mitchell

USF Tampa Graduate Theses and Dissertations

The gender difference in crime is indisputable. In an attempt to explain gender differences in adolescents' involvement in crime, secondary data analysis of middle and high school students and their neighborhoods will be examined. Feminists have identified the concept of patriarchy as the root of gender differences in all behavior and particularly in criminal behavior. Hagan's Power-Control Theory incorporates the concept of patriarchy through measures within home to examine how differences in occupational authority between parents affects the gender difference in delinquency through differential controls placed on sons and daughters. However, it has been suggested that the measure of patriarchy …

A Quasi Yagi Antenna With End Fired Radiation Over A Metal Ground, Sergio E. Melais

USF Tampa Graduate Theses and Dissertations

This dissertation presents a detailed investigation on the development of a quasi Yagi antenna with end fire radiation at 2.4 GHz (ISM band) over a metal reflector. Realization of an end fire radiator on top of a metal ground is very difficult because the reflected waves and image currents from the ground degrade the frequency bandwidth and steer the radiation pattern in the broadside direction. This destructive interference is reduced in this research through two quasi Yagi-ground configurations. The first arrangement utilizes a substrate of suitable thickness (7.5mm-0.19 ?g) to displace the ground away from the antenna. The second design …

Behavioral Skills Training With Teachers: Maintenance And Booster Training, Israel B. Miller

USF Tampa Graduate Theses and Dissertations

Behavioral skills training (BST) has been employed within many different populations to effect change in the way of reduction or acquisition of behaviors. For this study, a multiple-baseline across participants and modified ABAB design were employed. Analogue assessments and in-situ probes were conducted with three teachers following an initial training which occurred several months previously. These pre-assessments were followed by a separate booster training session for each individual teacher which lasted three and a half hours or less. Following the training, analogue and in-situ post assessments were conducted with each teacher. The independent variable was the booster training and the …

Review Of Kate Field: The Many Lives Of A Nineteenth-Century American Journalist And Maria Mitchell And The Sexing Of Science: An Astronomer Among The American Romantics, Melissa J. Homestead

Department of English: Faculty Publications

Literary historians writing biographies have increasingly shifted from critical biography (the author’s life as a means to interpret his or her literary works) to cultural biography (an author’s life and works in various cultural contexts). As literary historians whose biographical subjects (both nineteenth-century American women) are not primarily literary figures, Bergland and Scharnhorst represent a further step away from critical biography.

As a journalist (and popular lecturer, advocate of reform, playwright, and actress), Kate Field is a more literary figure than astronomer Maria Mitchell, but Scharnhorst has produced neither a critical nor a cultural biography. Instead, he presents a chronological …

Review Of Axes: Willa Cather And William Faulkner And Violence, The Arts, And Willa Cather, Melissa J. Homestead

Department of English: Faculty Publications

Willa Cather and William Faulkner represent an intriguing and potentially productive pairing for comparative study. Their works and careers are located at the rich intersection between regional ism and modernism, and both early 20th-century writers often looked back to the 19th century in their fiction. Even in the absence of influence or intertextual reference, these commonalities would give a literary historian much to say. However, in her study of these two authors, Merrill Maguire Skaggs exhaustively catalogs similarities and differences as proof of a decades-long competition between the authors at the expense of depth and subtlety in her analysis of …

The Priestly Imagination: Thomas Merton And The Poetics Of Critique, Michael W. Higgins

Mission & Culture Publications

The article looks at the representation of ideals of the poet-priest in the works of Thomas Merton. It provides an analysis of Merton's poetics of critique. For Merton, John the Baptist represents the model anchorite as well as the first Cisterician and the greatest Trappist. The indivisible and comprehensive dimensions of Merton as a whole man are represented by John the Baptist, John of the Cross and John the Beloved. The two types of Merton's poetics of critique are ecclesial/monastic and societal.

One Generation Consuming The Next: The Racial Critique Of Consumerism In George Romero’S Zombie Films, Henry Powell

Honors Theses

The racial and economic hierarchies in Romero’s films are complex. Each film shows a strong connection between wealthy and white, which rules over the poor and black or Hispanic. In each of his films, the Americans he shows us are so ingrained in their consumer or racist identities that they cannot look past them even in a time when the characters should only be doing what is important to survive. In Night, Harry dies because of his blind selfishness and bigotry against the African American man who attempts to look out for the group. Stephen and Roger both die because …

"Ain't You Heard"?: The Jazz Poetry Of Langston Hughes, Kristin Taylor

Theses and Dissertations

It all began with a piano bench. At the age of four, I sat next to my first piano teacher, as she told me the names of the keys. 'This is C, D, E . . . ," she said, her finger touching each key. moving through the entirety of a C-major scale. Afterward she asked, "Now. which one is F?" Though I touched the incorrect key, A instead of F, I remember being fascinated by the realization that I could create music by depressing those keys, making little wooden hammers strike strings in the piano's hidden belly. That fascination …

Caregivers Of Adults With Intellectual Disabilities: The Relationship Of Compound Caregiving And Reciprocity To Quality Of Life, Elizabeth A. Perkins

USF Tampa Graduate Theses and Dissertations

This study investigated the relationship between compound caregiving (i.e. multiple caregiving roles), and reciprocity to the wellbeing of older caregivers of adult children with intellectual disabilities. The study sample was composed of 91 caregivers with a mean age of 60 years. Participants were a convenience sample of caregivers predominantly residing in Florida. Care recipients' mean age was 29 years. Thirty-four were currently compound caregivers. Quality of life indicators used as outcome measures in this dissertation were life satisfaction, depressive symptomatology, physical health, mental health, and desire for alternative residential placement of the care recipient. Compared with the non-compound caregivers, the …

Using Social Stories And Behavior Skills Training Involving Family Members To Increase Social Skills For A Child With Autism, Jamie Leigh Powell

USF Tampa Graduate Theses and Dissertations

This study compared the effectiveness of a social story intervention with a social story plus behavior skills training intervention involving family members for a child with autism. A multiple baseline across siblings design was used to assess the impact of the intervention on social interaction of the child with autism, as well as the social interaction of the child's siblings. The siblings implemented both phases of the intervention. Social validity measures were taken from the siblings and parents, treatment integrity and generalization were assessed as well. The results indicated that the social interactions of the child with autism and the …

Proxy Records Of Climate Change In Subtropical And Tropical Karst Environments, Jason Samuel Polk

USF Tampa Graduate Theses and Dissertations

Understanding the paleoclimate of a region is important, especially when trying to determine the extent of natural climate variability within the context of anthropogenic impacts. Recent anomalous periods of climate change in the Late Holocene, including the Little Ice Age and Medieval Warm Period, could possibly repeat in the future, having significant worldwide consequences. This holds especially true for tropical and subtropical karst environments, where limited paleoclimate proxies provide minimal data regarding past climate change. An investigation into past climate change in Belize using fulvic acids from cave sediments shows periods of drought during the collapse of the Maya society …

Baseband Receiver Algorithms For 4g Co-Channel Femtocells, Mustafa Sahin

USF Tampa Graduate Theses and Dissertations

The growing interest for high data rate wireless communications over the last few decades gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity of frequency spectrum has been forcing wireless system designers to develop methods that will push the spectral elciency to its limit. One such method is to have multiple systems utilize the same spectrum by allowing some unavoidable interference to occur between them. The idea of co-channel systems is tested in the industrial, scientific and medical (ISM) bands and it is found to be a very beneficial approach. Therefore, it can be …

A Natural History Of The Mind : Edwards, Emerson, Thoreau, Melville, Michael Edmund Jonik

Legacy Theses & Dissertations (2009 - 2024)

This project examines how eighteenth- and nineteenth-century American writers drew on European natural science and philosophy - specifically in terms of concepts of form, perception, and experience - to open new possibilities for thinking the relationship between the mind and the physical world. In each of the moments of American intellectual history here considered - the natural theology of Calvinism, the idealistic natural history of Transcendentalism, and the movement towards an evolutionary process-philosophy of Pragmatism - "place" becomes not only geographical location, but a dynamic field of interactions of natural historical, literary, theological, and philosophical knowledge. I trace this through …

Quiet Testimony : The Ethical Impulse Of Silence In Emerson, Douglass, Melville, And James, Shari Goldberg

Legacy Theses & Dissertations (2009 - 2024)

This project proposes that Ralph Waldo Emerson, Frederick Douglass, Herman Melville and Henry James invoke silence in order to make evident, if not audible, the oppression of slaves and the absence of the dead. Challenging the opposition between advocacy and quietism that has largely structured scholarship on nineteenth-century American literature, I argue that these writers produce testimony by engaging voicelessness in their texts. In effect, their work revises the idea that testimony consists in a first-person report of past events. Quiet Testimony consequently suggests that, in signal American texts, political claims may not be explicitly argumentative, a testifying subject bears …

The Cultural And Literary Discourse Of War In 20th Century America, Robert Michael Ficociello

Legacy Theses & Dissertations (2009 - 2024)

In The Cultural and Literary Discourse of War in 2oth-century America, war is re-examined and re-historicized from an American perspective. First, war is contextualized in relation to urban studies, anthropology and literature. The dominant model, war is an extension of politics, for the analysis of war is decentered, and politics becomes the extension of war. In respect to America since the Revolutionary War, the nation is literally birthed from war, and the nation becomes an extension of that war. The perpetual re-writing of that war is seen through the discourses of history, politics, and literature. Therefore, the Cold War can …

Specular Subjects : Technologies Of Vision In The Transatlantic Novel, 1719-1850, Matthew Henry Pangborn

Legacy Theses & Dissertations (2009 - 2024)

Scholars of the long eighteenth century have traced the rise in modern Anglophone culture of an observational, episto-factual standard of truth and value, new techniques of surveillance and disciplinarity, image-based and global networks of consumption and exchange, and a mass culture honing its ostensibly comprehensive power of sight through new media of text and image. While debate has occurred over the origins and meanings of the ascendancy of such an overwhelmingly visual mode of engagement with the world, scholars have tended to examine such topics in isolation, with little attention to the ethical and political consequences of the material practices …

The Willa Cather Archive In The Classroom, Andrew Jewell

University of Nebraska-Lincoln Libraries: Faculty Publications

This essay discusses many of the opportunities for teachers I believe are present in the Willa Cather Archive (http://cather.unl.edu), particularly in the way the Archive makes new materials available or older materials available in a new way. Additionally, this essay suggests some of the implications of the Archive’s digital presentation of resources. However, the place of digital scholarship in academic life is still evolving, and students and teachers are just getting accustomed to using the form. Given this circumstance, many of my thoughts are inconclusive, observations based upon preliminary understandings into how this resource affects our classrooms. I avoid confident …

Female Captivity Narratives In Colonial America, Kathryn O'Hara

The Gettysburg Historical Journal

The female captivity narrative provides a complex view of colonial American history by recounting the experiences of women captured from their colonial homes by Native Americans. Male editors, often family friends or town ministers, generally compiled the experiences of female captives, and separating the voice of the female captive from influence of the male editor presents a challenge. Puritan captivity narratives in particular demonstrate conflict between attempts by Puritan ministers to impose a unified religious message in the sagas and the captives’ individual experiences, which often contradicted Puritan doctrine. During the early colonial era, ministers’ attempts to promote the Puritan …
