The Sociopolitical Construction Of Race And Literary Representations Of The Biracial Subject, Kara Fontenot Jan 2006

The Sociopolitical Construction Of Race And Literary Representations Of The Biracial Subject, Kara Fontenot

Electronic Theses and Dissertations

Twentieth-century American literature incorporates interracial and biracial themes that bring to light the often unnamed and unrecognized biracial identities of many Americans. Unfortunately, despite the potential value for a deeper understanding of the construction of race, these themes have seldom been seriously considered in the context of reevaluating the nature of the system that creates racial labels and categories until the recent emergence of postmodern critical theories. This thesis examines the black-white interracial themes and biracial protagonists in Nella Larsen's Quicksand (1928) and Danzy Senna's Caucasia (1998) in order to explore the texts' representations of systems of hegemonic ...

Modeling Autonomous Agents In Military Simulations, Varol Kaptan

Electronic Theses and Dissertations

Simulation is an important tool for prediction and assessment of the behavior of complex systems and situations. The importance of simulation has increased tremendously during the last few decades, mainly because the rapid pace of development in the field of electronics has turned the computer from a costly and obscure piece of equipment to a cheap ubiquitous tool which is now an integral part of our daily lives. While such technological improvements make it easier to analyze well-understood deterministic systems, increase in speed and storage capacity alone are not enough when simulating situations where human beings and their behavior are ...


Developing Microscopic Toll Plaza Model Using Paramics, Nezamuddin Nezamuddin Jan 2006

Developing Microscopic Toll Plaza Model Using Paramics, Nezamuddin Nezamuddin

Electronic Theses and Dissertations

Simulation modeling is the most cost-effective way of studying real life transportation problems, either existing or anticipated, without disturbing the balance of the transportation system. There is a vast suite of simulation models available in market, ready to choose from macroscopic, mesoscopic, or microscopic in nature, to study different transportation system elements like freeways, highways, signalized and un-signalized intersections. However, most of these network simulation models, like PARAMICS, VISSIM, CORSIM … etc, do not come readily available with built in toll plaza models. On the other hand, many researchers have independently developed toll plaza models, which can only model an isolated ...


Examining Employee Use Of Family-Friendly Benefits With The Theory Of Planned Behavior, Heather Seiser Jan 2006

Examining Employee Use Of Family-Friendly Benefits With The Theory Of Planned Behavior, Heather Seiser

Electronic Theses and Dissertations

The purpose of the present study was to investigate the factors that may be related to employees' decisions to use the family-friendly benefits (e.g., maternity/paternity leave, flexible work schedule) that are offered to them by their employers. Research has shown that both employees and organizations benefit when employees use family-friendly benefits. However, research has also shown that many employees do not take advantage of such benefits. Studies examining this issue are limited, and much of the research that has been conducted is anecdotal and atheoretical. The present study overcame this problem by empirically examining the use of family-friendly ...


Object Association Across Multiple Moving Cameras In Planar Scenes, Yaser Sheikh Jan 2006

Object Association Across Multiple Moving Cameras In Planar Scenes, Yaser Sheikh

Electronic Theses and Dissertations

In this dissertation, we address the problem of object detection and object association across multiple cameras over large areas that are well modeled by planes. We present a unifying probabilistic framework that captures the underlying geometry of planar scenes, and present algorithms to estimate geometric relationships between different cameras, which are subsequently used for co-operative association of objects. We first present a local1 object detection scheme that has three fundamental innovations over existing approaches. First, the model of the intensities of image pixels as independent random variables is challenged and it is asserted that useful correlation exists in intensities of ...


Quantitative High-Angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science, Rumyana Petrova Jan 2006

Quantitative High-Angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science, Rumyana Petrova

Electronic Theses and Dissertations

Scanning transmission electron microscopy (STEM) has been widely used for characterization of materials; to identify micro- and nano-structures within a sample and to analyze crystal and defect structures. High-angle annular dark field (HAADF) STEM imaging using atomic number (Z) contrast has proven capable of resolving atomic structures with better than 2 A lateral resolution. In this work, the HAADF STEM imaging mode is used in combination with multislice simulations. This combination is applied to the investigation of the temperature dependence of the intensity collected by the HAADF detector in silicon, and to convergent beam electron diffraction (CBED) to measure the ...


Simplified Low Copy Number Dna Analysis By Post Pcr Purification, Pamela Smith Jan 2006

Simplified Low Copy Number Dna Analysis By Post Pcr Purification, Pamela Smith

Electronic Theses and Dissertations

Frequently evidentiary items contain an insufficient quantity of DNA to obtain complete or even partial DNA profiles using standard forensic gentotyping techniques. Here, various methods of post PCR purification were evaluated for their effects on the sensitivity of fluophore-based allelic detection. A method of post PCR purification is described which increases the sensitivity of standard 28 cycle PCR such that low copy number DNA templates (<100 pg DNA) can be analyzed. Full profiles were consistently obtained with as little as 20 pg template DNA without increased cycle number. In mock case type samples with dermal ridge fingerprints, genetic profiles were obtained by amplification with 28 cycles followed by post-PCR purification whereas no profiles were obtained without purification of the PCR product. Allele drop-out, increased stutter, and contamination (allele drop-in) typical of LCN analysis were observed. A single incident of contamination was observed in a reagent blank (not duplicated upon re-amplification) however, no contamination was observed in negative amplification controls.


Police Organizational Performance In The State Of Florida:Confirmatory Analysis Of The Relationship Of The Environment And Design Structure To Performance, Jeffrey Goltz Jan 2006

Police Organizational Performance In The State Of Florida:Confirmatory Analysis Of The Relationship Of The Environment And Design Structure To Performance, Jeffrey Goltz

Electronic Theses and Dissertations

To date, police organizations have not been rigorously analyzed by organizational scholars and most analysis of these organizations has been captured through a single construct. The purpose of this study is to develop confirmatory police organizational analysis by validating a multi-dimensional conceptual framework that explains the relationships among three constructs: environmental constraints, the design structures of police organizations, and organizational performance indicators. The modeling is deeply rooted in contingency theory, and the influence of isomorphism and institutional theory on the covariance structure model are investigated. One hundred and thirteen local police organizations from the State of Florida are included in ...


Public Religious Participation: A Comparison Of Three Distinct Birth Cohorts, Diane Prather Jan 2006

Public Religious Participation: A Comparison Of Three Distinct Birth Cohorts, Diane Prather

Electronic Theses and Dissertations

Research has demonstrated that many factors affect levels of religiosity in American religion. This study extends the research on the relationship between cohort membership and public religious participation and individual personal involvement. Most of the research pertaining to the effects of cohort on religiosity has been devoted to comparisons between the Depression Era and Baby Boom Cohorts. This study extends research in this area by including Generation X to the extent possible. Using the General Social Surveys, this analysis employs an age/period/cohort analytical framework to examine religious involvement. Sociodemographic variables that are associated with religiosity are included in ...


A Life Cycle Software Quality Model Using Bayesian Belief Networks, Justin Beaver Jan 2006

A Life Cycle Software Quality Model Using Bayesian Belief Networks, Justin Beaver

Electronic Theses and Dissertations

Software practitioners lack a consistent approach to assessing and predicting quality within their products. This research proposes a software quality model that accounts for the influences of development team skill/experience, process maturity, and problem complexity throughout the software engineering life cycle. The model is structured using Bayesian Belief Networks and, unlike previous efforts, uses widely-accepted software engineering standards and in-use industry techniques to quantify the indicators and measures of software quality. Data from 28 software engineering projects was acquired for this study, and was used for validation and comparison of the presented software quality models. Three Bayesian model structures ...


Performance Efficacy Using A Comparison Of Commerical And In-House Y-Str Multiplex Systems For Operational Use, Kathleen Mayntz-Press Jan 2006

Performance Efficacy Using A Comparison Of Commerical And In-House Y-Str Multiplex Systems For Operational Use, Kathleen Mayntz-Press

Electronic Theses and Dissertations

It is routine for the forensic scientist to obtain a genetic profile of an individual from DNA recovered from a biological stain deposited at a crime scene. In contrast, only a limited number of laboratories in the United States have the capability of performing Y-STR analysis in casework. In order to aid in facilitating the transfer of Y-STR technology to the crime laboratory community for operational use, a comparison between commercial products from three main vendors (Applied Biosystems AmpFLSTR Yfiler PCR Amplification Kit, Promega PowerPlex - Y System, Reliagene Y-PLEX 12) and two in-house Y-STR multiplexes (MPI and MPB) commenced. The ...


General Social Trust And Political Trust Within Social And Political Groups: A Case Study, Weylan Craig Jan 2006

General Social Trust And Political Trust Within Social And Political Groups: A Case Study, Weylan Craig

Electronic Theses and Dissertations

People in society with high levels of generalized social trust and political trust are more likely to engage in civic activism and participation. Therefore, people involved in social and political groups will likely have higher levels of generalized social and political trust than the general public. What lacks in this realm of scholarship is a solid comparison of trust among people involved in social and political groups. This case-study analysis of generalized social trust and political trust among social and political groups shows the trust that is not only generated within each group, but also which types of groups are ...


The Paths To Becoming A Mathematics Teacher, Kimberly Lowry Jan 2006

The Paths To Becoming A Mathematics Teacher, Kimberly Lowry

Electronic Theses and Dissertations

Increasing numbers of mathematics teachers must be recruited in coming years, because of a growing student population, teacher attrition, calls for smaller class size, and the need to replace out-of-subject teachers. Recruitment can be made more effective and efficient, if better information on career paths is provided to decision makers. This study attempts to analyze the academic decisions which lead to the outcome "becoming a mathematics teacher". Four groups were compared and contrasted: mathematics teachers, science teachers, other teachers, and non-teachers. Science teachers were removed from the "other teachers" category because of their many similarities to mathematics teachers on the ...

An equation for the growth of Hypericum cumulicola is developed through analyzing how the distance to and the height of the nearest Ceratiola ericoides (Florida rosemary) affects the growth of Hypericum cumulicola. The hypericums were separated into five separate regions according to the distance to the nearest rosemary plant. The parameters for a basic growth equation were obtained in each of the five regions and compared to each other along ...


Effects Of Atmospheric Turbulence On The Propagation Of Flattened Gaussian Optical Beams, Doris Cowan Jan 2006

Effects Of Atmospheric Turbulence On The Propagation Of Flattened Gaussian Optical Beams, Doris Cowan

Electronic Theses and Dissertations

In an attempt to mitigate the effects of the atmosphere on the coherence of an optical (laser) beam, interest has recently been shown in changing the beam shape to determine if a different power distribution at the transmitter will reduce the effects of the random fluctuations in the refractive index. Here, a model is developed for the field of a flattened Gaussian beam as it propagates through atmospheric turbulence, and the resulting effects upon the scintillation of the beam and upon beam wander are determined. A comparison of these results is made with the like effects on a standard TEM00 ...


Wide Viewing Angle Liquid Crystal Displays, Qi Hong Jan 2006

Wide Viewing Angle Liquid Crystal Displays, Qi Hong

Electronic Theses and Dissertations

In this dissertation, novel phase compensation technologies are applied to the designs of wide viewing angle and high transmittance liquid crystal displays.

Next, to increase the bright state transmittance while maintain the high contrast. Finally, to reduce the cost and improve the applicability of the broadband and wide-view circular polarizer, the device configuration of the broadband and wide-view circular polarizer is significantly simplified by the application of biaxial compensation ...


Between Continents, Mona Hassan Jan 2006

Between Continents, Mona Hassan

Electronic Theses and Dissertations

Between Continents is a collection of thirty-two poems. The most challenging aspect of finding the right voice and the appropriate metaphors in "Between Continents" has been the difficulty in assimilating a diversity of traditions within my own work. The polarity of aesthetic values is a well known feature of contemporary American poetry. Charles Webb in his essay on the competing aesthetics in poetry uses the metaphor of apples and orangutans to point out how exaggerated this difference really is. Jorie Graham sees in the way young writers today are simultaneously influenced by elements of poets whose philosophies mutually exclude each ...


Dynamic Entrepreneurial Networks: An Investigation Of Entrepreneurs, New Ventures And Their Networks, Diane Sullivan Jan 2006

Dynamic Entrepreneurial Networks: An Investigation Of Entrepreneurs, New Ventures And Their Networks, Diane Sullivan

Electronic Theses and Dissertations

Entrepreneurs need resources to organize new venture offerings into marketplace-acceptable forms. Entrepreneurs use others' assistance via networks to obtain these resources. Research indicates that firms face resource dependencies, that likely change over time, where they must respond to those controlling resources. Although some work has investigated implications of new ventures' networks at one time period, little work has investigated the dynamic nature and associated outcomes of networks as they change due to different resource requirements as the venture develops. This research examines the dynamic nature of networks, due different resource requirements over time, and how these changes impact entrepreneurial outcomes ...


On The Use Of Variable Coherence In Inverse Scattering Problems, Erwan Baleine Jan 2006

On The Use Of Variable Coherence In Inverse Scattering Problems, Erwan Baleine

Electronic Theses and Dissertations

Even though most of the properties of optical fields, such as wavelength, polarization, wavefront curvature or angular spectrum, have been commonly manipulated in a variety of remote sensing procedures, controlling the degree of coherence of light did not find wide applications until recently. Since the emergence of optical coherence tomography, a growing number of scattering techniques have relied on temporal coherence gating which provides efficient target selectivity in a way achieved only by bulky short pulse measurements. The spatial counterpart of temporal coherence, however, has barely been exploited in sensing applications. This dissertation examines, in different scattering regimes, a variety ...

Cognitive Training Transfer Using A Personal Computer-Based Game:A Close Quarters Battle Case Study, Michael Woodman Jan 2006

Cognitive Training Transfer Using A Personal Computer-Based Game:A Close Quarters Battle Case Study, Michael Woodman

Electronic Theses and Dissertations

Developers of Commercial off the Shelf (COTS) gaming software are making remarkable strides in increasing the realism of their software. This realism has caught the attention of the training community, which has traditionally sought system and operational replication in training systems such as flight simulators. Since games are designed and marketed for entertainment and not designed for training of tasks, questions exist about the effectiveness of games as a training system in achieving the desired transfer of skills to the actual environment. Numerous studies over the past ten years have documented that PC-based simulation training environments can offer effective training ...
