Pech Family: Kun Tuy (Middle), Lindsey Gaines

Cambodian American Stories

Imagine a 15-year-old girl forced to work in the fields, seven days a week, from five in the morning until seven at night. In the U.S., such a young woman would be going to school to learn about herself and about life’s opportunities. Kun Tuy dreamed of teaching dance. Instead, she was put to work by the Khmer Rouge in the rice fields of mountainous Cambodia. She received no money and little food for her labor. The Khmer Rouge ruled by suppression and killing in anticipation of establishing a Communist regime in Cambodia…

Effect Of Heat Treatments And Reduced Absorber Layer Thickness On Cu(In,Ga)Se2 Thin Film Solar Cells, Vinodh Chandrasekaran

USF Tampa Graduate Theses and Dissertations

Thin film solar cells with Copper Indium Gallium Diselenide (Cu(In,Ga)Se₂) absorber layers is one of the most promising candidates to emerge as an efficient solar cell technology in the near future. CIGS cells with efficiencies of 19.2 % have already been reported [1]. In this study, CIGS absorber layers are fabricated by a two-stage all-solidstate manufacture-friendly process. In the first stage, designated as precursor deposition, Copper and Gallium are sequentially deposited followed by co-deposition of Indium and Selenium. In the second stage, designated as selenization, the substrate is annealed at high temperatures in a selenium environment during which …

Gary Paul Nabhan, Gioia Woods

Western Writers Series Digital Editions

Between spoonfuls of posole at the Morning Glory Cafe in Flagstaff, Arizona, Gary Paul Nabhan mused about the distinctive character of western American literature. “What is western literature about?” I asked him. Without hesitation, he replied, “It is about a process of disorientation and reorientation.” The mountains, sand dunes, and canyons of the western landscape govern western imagination. That landscape, he believes, is responsible for the dis- and reorientation that characterizes the work of many western writers. Nabhan continued, “I should say that in an odd way, that’s even true of Native American literature [....] Leslie Silko writes about the …

Josephine Miles, Erik Muller

Western Writers Series Digital Editions

“You could say I saw California grow up. Right along with me!” So Josephine Miles linked her life and region (Childress 40). The link between her poetry and California has not always been declared by the poet or detected by her readers. Miles mused upon the problem: “Sometimes there’s a certain kind of critic that says I’m a California poet [. . .] he says I have a lot of loose lines and a lot of locale. But then another critic will say, ‘She’s not to be identified as anything but English because her poetry is rather neat and universal’” …

Louis Owens, Linda Lizut Helstern

Western Writers Series Digital Editions

“'I prefer infinitions to definitions,’” Alex Yazzie, the cross-dressing Navajo anthropologist in Louis Owens’ Bone Game, declares (46). So did Louis Owens. In his life, in his death, and above all in his writing, Louis Owens (1948-2002), novelist, essayist, literary and cultural critic, crossed boundaries and refused definitions. Born in Lompoc, California, Owens came to understand the arid landscape of the west through the lens of his early childhood in the Yazoo bottoms of Mississippi. He was a Native mixedblood who acknowledged not only his multi-tribal heritage, Choctaw on his father's side and Cherokee on his mother’s, but the …

Germans In Sacramento, 1850-1859, Carole C. Terry

Psi Sigma Siren

During the 1850s in Sacramento, German-born immigrants banded together in an ethnically based neighborhood where they created a sub-culture of "German-ness," practicing their own particular rituals and customs. At the same time, these foreign-born joined the Anglo-American majority to addresses the chaos and disorder brought on by the dramatic increase in Sacramento's population due to the discovery of gold in 1849. Contemporary accounts such as newspapers, directories, histories and unpublished manuscripts confirm the existence of this strong community and its attempts to duplicate institutions they remembered in Germany and ethnic settlements in America. Despite their small numbers, they influenced the …

Stigma Cities: Birmingham, Alabama And Las Vegas, Nevada In The National Media, 1945-2000, Jonathan Foster

Psi Sigma Siren

Early in 1994 Time magazine proclaimed Las Vegas, Nevada “The New All American City,” a “city so freakishly democratic” that Americans just could not resist. Twenty-three years earlier, Look magazine had conferred the same title upon Birmingham, Alabama, stressing its progress in race relations. Such media castings of normality must have surprised the American public in both instances. By the time of each city’s designation as “All-American,” the public had long been subjected to stories of their seemingly abnormal internal actions and qualities. Both cities suffered from stigmatized identities in the wider American perception that were fully formed by the …

Dollars, Defense, And The Desert: Southern Nevada’S Military Economy And The Second World War, Robert V. Nickel

Psi Sigma Siren

Modern Las Vegas has come to inhabit a unique place in the American imagination. A neon mirage glittering amid the desolate Mojave Desert, “Sin City” is both celebrated and scorned as an oasis of gambling, nightlife, and entertainment. Consistently ranked among the nation’s fastest-growing metropolitan areas, Las Vegas has experienced sensational economic, infrastructural, and demographic growth in recent years. The dizzying pace of this development makes it difficult to imagine that the city was once anything other than the bustling urban playground it is today. Like many great western cities, Las Vegas came of age during the World War Two …

Stress Diagnostics And Crack Detection In Full-Size Silicon Wafers Using Resonance Ultrasonic Vibrations, Anton Byelyayev

USF Tampa Graduate Theses and Dissertations

Non-destructive monitoring of residual elastic stress in silicon wafers is a matter of strong concern for modern photovoltaic industry. The excess stress can generate cracks within the crystalline structure, which further may lead to wafer breakage. Cracks diagnostics and reduction in multicrystalline silicon, for example, are ones of the most important issues in photovoltaics now. The industry is intent to improve the yield of solar cells fabrication. There is a number of techniques to measure residual stress in semiconductor materials today. They include Raman spectroscopy, X-ray diffraction and infrared polariscopy. None of these methods are applicable for in-line diagnostics of …

Assessing The Issue Of Arbitrariness In Capital Sentencing In North Carolina: Are The Effects Of Legally Relevant Variables Racially Invariant?, Judith Kavanaugh Earl

USF Tampa Graduate Theses and Dissertations

This study analyzed case and sentencing data from 632 capital cases involving Black and White defendants and victims, processed in North Carolina from May 1990 through December 2002. Logistic regression analysis of all cases and race-specific data allowed assessment of the variable effects of jury acceptance of statutory aggravating and mitigating factors on capital sentencing outcomes (death versus life). The purpose was to evaluate the role race plays in shaping jury use of legally defined factors in capital sentencing. Significant variance in the effect of jury acceptance of aggravators was observed between Black and White defendants. Black defendants pay a …

The Impact Of Victim-Offender Familial Relationships On Capital Sentencing Outcomes, Katharine D. Evans

USF Tampa Graduate Theses and Dissertations

This study is an investigation of whether familial relationships among offenders and their victims affect capital sentencing. Using a sample of capital cases from North Carolina restricted to familial homicides, logistic regression models are used while controlling for legal and extra-legal factors that influence decision outcomes. Such models of capital sentencing are developed to (1) determine whether familial-victim cases have unique correlates; and (2) whether there are variations in the effects of these correlates across gender. Contradictory to these hypotheses, results suggest that acquaintance and stranger relationships are less likely to receive a capital outcome when compared to familial relationships. …

Self-Control, Gang Membership, And Victimization: An Integrated Approach To The Risk Factors Of Violent Victimization, Kristina Childs

USF Tampa Graduate Theses and Dissertations

This study integrates one of the most empirically tested individual characteristics (self-control) with situational factors (risky lifestyle) in an attempt to explain the risks involved in violent victimization. Data came from a diverse sample of 3,907 middle school students who participated in the G.R.E.A.T. program during the 1993-1994 school year. Gang membership is used as a proxy variable to measure risky lifestyle. It is hypothesized that 1) gang membership will mediate the effect of self-control on violent victimization and 2) self-control and gang membership will interact to amplify the risk of violent victimization.

Logistic regression was used to analyze the …

Stability Studies Of Cdte Solar Cells Fabricated With Varying Amounts Of Cu In The Back Contact, Swetha Erra

USF Tampa Graduate Theses and Dissertations

Solar energy is one of the abundant, non-polluting renewable energy options in our planet. During the last three decades considerable progress has been achieved in developing technologies to produce electricity from solar radiation, but producing electricity with low cost and low pollution is of concern. The CdTe solar cells are the leading source for the production of cost effective solar cells. The main issue of concern in these CdTe solar cells is degradation observed when stressed at elevated temperatures. The degradation in CdTe solar cells can be attributed to the back contact, which often contains Cu to improve the electronic …

USF Tampa Graduate Theses and Dissertations

The area of particle characterization is expansive; it contains many technologies and methods of analysis. Light spectroscopy techniques yield information on the joint property distribution of particles, comprising the chemical composition, size, shape, and orientation of the particles. The objective of this dissertation is to develop a hybrid scattering-absorption model incorporating Mie and Rayleigh-Debye-Gans theory to characterize submicron particles in suspension with multiwavelength spectroscopy.

Rayleigh-Debye-Gans theory (RDG) was chosen as a model to relate the particles joint property distribution to the light scattering and absorption phenomena for submicron particles. A correction model to instrument parameters of relevance was implemented to …

Multichannel Functional Data Decomposition And Monitoring, Hani Kababji

USF Tampa Graduate Theses and Dissertations

With current advances in sensors and information technology, online measurements of process variables become increasingly accessible for process control and monitoring. Such measurements may take the shape of curves rather than scalar values. The term Multichannel Functional Data (MFD) is used to represent the observations of multiple process variables in the shape of curves. Generally MFD contains rich information about processes. The challenge of process control in MFD is that Statistical Process Control (SPC) is not directly applicable. Furthermore, there is no systematic approach to interpret the complex variation in MFD. In this research, our objective is to develop an …

Characterization Of L-Cysteine Thin Films Via Photoemission Spectroscopy, Roy Gargagliano

USF Tampa Graduate Theses and Dissertations

Using photoemission spectroscopy (PES) the interface between the amino acid Lcysteine and a Au substrate was characterized to determine its electronic and chemical structure. L-cysteine was deposited on a Au substrate in several experiments via dipping into solution or via evaporation. The depositions were performed in several steps. Between deposition steps x-ray photoemission spectroscopy (XPS) and ultraviolet photoemission spectroscopy (UPS) measurements were taken. XPS was used to characterize the chemical interaction at the interface while UPS was used to determine the orbital line-up at the interface and the highest molecular orbital (HOMO) structure of L-cysteine. The results indicate the formation …

Performance Oriented Scheduling With Power Constraints, Brian C. Hayes

USF Tampa Graduate Theses and Dissertations

Current technology trends continue to increase the power density of modern processors at an exponential rate. The increasing transistor density has significantly impacted cooling and power requirements and if left unchecked, the power barrier will adversely affect performance gains in the near future. In this work, we investigate the problem of instruction reordering for improving both performance and power requirements. Recently, a new scheduling technique, called Forced Directed Instruction Scheduling, or FDIS, has been proposed in the literature for use in high level synthesis as well as instruction reordering [15, 16, 6]. This thesis extends the FDIS algorithm by adding …

Rational Fraction Approximations For Passive Network Functions, William Joel Dietmar Johnson

USF Tampa Graduate Theses and Dissertations

In electrical engineering, the designer is often presented with the problem of synthesizing a circuit for which the mathematical specifications are unsuitable for physical realization. Hence, the engineer must approximate as well as possible the prescribed network function by another function which is realizable. This paper describes a new approximation method for solving the problem of realizing passive network transfer functions, where the realization is carried out through the use of passive, reciprocal, lumped, linear, and time-invariant elements.

Optical Response Of Polycrystalline Mercuric Iodide Photoconductive Detectors, Prashant Chegoor

USF Tampa Graduate Theses and Dissertations

Mercuric Iodide in its tetragonal form has received a lot of attention for many years as a prospective room temperature X-ray and y-ray detector. Its basic properties are well suited for this purpose. Its wide band gap of 2.1eV contributes to a high dark resistivity of 10¹²ohm-cm or higher. A high atomic number of its constituent atoms (Hg-80, I -53) and a density of 6.3g/cm³ result in its efficient interaction with incident X-ray or y-ray radiation. Single crystalline mercuric iodide has been thoroughly studied and successfully utilized in commercial radiation detectors. But with the urgent need for …

Leakage Power Driven Behavioral Synthesis Of Pipelined Asics, Ranganath Gopalan

USF Tampa Graduate Theses and Dissertations

Traditional approaches for power optimization during high level synthesis, have targetted single-cycle designs where only one input is being processed by the datapath at any given time. Throughput of large single-cycle designs can be improved by means of pipelining. In this work, we present a framework for the high-level synthesis of pipelined datapaths with low leakage power dissipation. We explore the effect of pipelining on the leakage power dissipation of data-flow intensive designs. An algorithm for minimization of leakage power during behavioral pipelining is presented. The transistor level leakage reduction technique employed here is based on Multi-Threshold CMOS (MTCMOS) technology. …
