New Frontiers in American Documentary Film

Nicole Jan Huffman
Despite economic hardships, there was a tremendous impulse in the Depression Era to document actual events and people. One of the new genres of "documentary expression" that emerged during these years was documentary film. Using the camera, artists could capture a worker's revolt, a farmer and his family trying to survive on the overworked land, fighting in the Spanish Civil War, and the impact of the machine on man and the land. No other apparatus...

A Viscoelastic Model for High Strain Rate Loading of the Human Calvarium

Sourabh Boruah
Brain injury resulting from exposure to blast continues to be a significant problem in the military community. In order to understand the response of the human brain under various high-rate mechanical insults to the head, the way in which the load is transmitted through the skull must be accurately characterized. The bones of the human calvarium comprise a sandwich structure with two dense layers of cortical bone separated by porous cancellous bone. Although the high...

Detection of steady state in discrete event dynamic systems : an analysis of heuristics

Mary Alice McClarnon
The choice of initial conditions is a fundamental issue in the experimental analysis of non-terminating, stochastic, discrete-event dynamic systems (DEDS). Because output observations are sequentially correlated, cumulative performance estimators are biased when initial observations are not representative of steady-state operation. A poor choice of initial conditions, at best, requires a larger sample of steady-state operations so as to dilute the initialization bias. At worst, the bias goes undetected, and the result is that insufficient data...

Thomas Cussons Fletcher
Describes the training and education of a typical aspirant to knighthood of the late fourteenth or early fifteenth century. Uses Chaucer's references to squires in the 'Tales' as well as additional material from the contemporary romances and prose works.

Research in Japanese Optical Character Recognition

Trent A. Duewer
The purpose of this project was to explore and learn better ways to do Japanese Optical Character Recognition (OCR). I researched Japanese OCR by writing a simple program that can recognize some Japanese characters. OCR is scanning in a written document and converting the pictures of characters inside the document into text. OCR is a laborsaving device because it eliminates the need to type a written document into the computer. The program developed in this...

Electronic Submission of Undergraduate Theses: A Case Study for the Implementation of a University-Wide Program for the Electronic Submission and On-line Archiving of Theses and Dissertations

Mariahna Moore
The popularity of electronic publishing and electronic libraries rises as the number of people on the World Wide Web increases exponentially every year. Many students are not suitably prepared for on-line world that faces them in their careers ahead. Additionally, the results of hours of time, energy, and research are seemingly lost as theses and dissertations sit on library shelves unavailable to outside students and research communities. Increasingly, discussions of electronic theses and dissertations and...

The MatchMaker DataBase (MMDB): Bringing Businesses and Consultants Together

Roy E. Stephan
In today's technical industries, there is a serious lack of skilled workers. Many companies are resorting to hiring unskilled workers and teaching them the technologies they need to do their jobs. For large or deadline intensive projects, companies rely on consultants. The major problem with this system is that companies cannot find consultants with the skills they need in a timely or efficient fashion. The MatchMaker program is a web-based business tool for putting companies...

An introduction and translation of Vinitadeva's explanation of the first ten verses of (Vasubandhu's) commentary on his \"Twenty Stanzas\" with appended glossary of technical terms Gregory Alexander Hillis.

Gregory Alexander Hillis
In this thesis I argue that Vasubandhu categorically rejects the position that objects exist external to the mind. To support this interpretation, I engage in a close reading of Vasubandhu's Twenty Stanzas (Vimśatikā , nyi shu pa), his autocommentary (vimśatikā-vrtti, nyi shu pa'i 'grel pa), and Vinītadeva's sub-commentary (prakarana- Vimśaka-tīkā-, rab tu byed pa nyi shu pa' i 'grel bshad). I endeavor to show how unambiguous statements in Vasubandhu's root text and autocommentary refuting the...

The Relationship among Housing Instability, Race/Ethnicity, Depressive Symptoms, and Exposure to Intimate Partner Violence among Mothers

Patty Wilson
Background: Mothers who experience ongoing intimate partner violence (IPV) with limited finances, unemployment, and housing instability (HI) may find themselves trapped in situations where they stay in abusive relationships or return to their abuser, increasing their exposure to IPV. The racial disparities in rates of IPV, depressive symptoms, and HI between Black women and White women is alarming. Little is known of the influence that race/ethnicity has on the relationship between HI, depressive symptoms, and...

A Retrospective Evaluation of Traffic Forecasting Accuracy: Lessons Learned from Virginia

Salwa Anam
Understanding the accuracy of techniques for forecasting traffic volumes for a future year, such as extrapolation of previous years traffic volumes, use of regional travel demand models, and use of local trip generation rates, can aid analysts in considering the range of transportation investments for a given location. To determine this accuracy, forecasts from 39 Virginia studies (published from 1967-2010) were compared to observed volumes for the forecast year. The comparison enabled the identification of...

Carbon assimilation by riverine mangroves in the Florida Everglades

Jordan Barr
This dissertation addressed the central hypothesis that Florida Everglades' mangroves are among the most productive of all biomes, in terms of their capacity to assimilate atmospheric carbon dioxide. The hypothesis was evaluated using both a foliage-level gas exchange system and tower-based observing systems operating at the ecosystem-dimension during January through August 2004. Leaf-level controls on gas and energy exchange were investigated for black and red mangrove foliage along the water's edge and inside the canopy...

Capturing the Role of Temperature and Entropy in Crystal Polymorphs Through Molecular Simulations

Eric Dybeck
The presence of multiple stable crystal structures in solid organic materials can limit their commercial viability when two or more observable polymorphs exhibit markedly different physical properties. Unintended restructuring events have hindered pharmaceutical solid form development in numerous therapeutic candidates and have led to costly market recalls. Conversely, intentional synthesis of a metastable form has led to significantly more favorable performance in numerous materials. Current computational methods for predicting polymorphic behavior evaluate candidate crystal structures...

Understanding the Chromatographic Processing of Recombinant Human Papillomavirus Vaccine Using Ceramic Hydroxypatite

Yiran Wang
Virus like particles (VLPs) are novel biopharmaceutical products that have become widely used for vaccines, gene therapy and immunotherapy. The purification of VLPs poses several unique challenges including the handling of their large molecular size and the removal of nucleic acid contaminants. Ceramic hydroxyapatite (CHT), a mixed-mode chromatography adsorbent, has shown promise in purifying VLPs from nucleic acid due to its multimodal adsorption mechanism. This work has two principal objectives. The first is to investigate...

A Revolution (Dis)Placed: Environment and the Creation of Cultural Identity in Fernández, Yáñez, Castellanos, and Poniatowska

Stephanie Gates
Mexican history and culture are particularly illuminating when considering the question of environment and the significance a society places on it. This dissertation analyzes four works from post-revolutionary Mexico that span from the years 1943-1969, by examining how the space in each work interacts with characters to create meaning. Through it, a sense of identity—cultural and historical—emerges which is heavily dependent on environmental space. The works studied in each chapter are: Emilio Fernández’s 1943 film,...

The Use of Impedance Spectroscopy in Characterizing Low Voltage Electrowetting-on-dielectric

Xiaoyu Hu
Being able to control fluid shape and flow using an external electric field alone without any mechanical parts, electrowetting-on-dielectric (EWOD) has drawn a lot of attention from researchers which leads to the the invention of many interesting applications. In the laboratory, EWOD characterization is generally conducted using direct optical observation of the droplet. While being a straight-forward method, optical techniques are laborious, slow, subject to optical distortions, and impractical in devices where the electrowetted droplet...

Multicarrier OFDM with Application to Adaptive Spectrum Utilization: A Design Study

Marc Severo
As the demand for wireless spectrum exceeds regulatory allocation, there is a need to look at new ways to manage and utilize unused spectrum. One method is to use smart, or cognitive radios that are able to sense and utilize unused spectrum. As the bandwidth requirements for these adaptive radios increase, there is a need to aggregate the data over non-contiguous channels over a wide bandwidth. This requirement of both being adaptive and flexible proposes...

The Undiscovered Thurman: The Early Howard Thurman and Religious Liberalism Unfinished Business of Race Relations

Larry Perry
The Undiscovered Thurman: the Early Howard Thurman and the Religious Left’s Unfinished Business of Race Relations (1899 to 1949) is an intellectual and political biography of the early Howard Thurman. While it is a biography of Thurman, it is just as much a biography of the numerous zeitgeists, circumstances, and institutions that produced him. This detailed account of the early Thurman and the world around him points one towards a more politically radical and philosophically...

A Dynamic Model of Multiproduct Firms: Advertising and Product Menu Choice in the Ready-to-Eat Cereal Industry

Jason Price Hulbert
A common assumption in the industrial organization literature is that of exogenous product menus. While this assumption is adequate for short run models of firm behavior, long run analysis of competition requires a model that explains the evolution of the menus upon which the short run competition is based. This dissertation provides such a model. The objective of this dynamic model of multiproduct oligopoly is to understand how firms compete through menu selection in the...

Choice in Washington: the Politics of Liberalized Abortion

Robert Gerald Morrison
This thesis is a study of Washington's statewide referendum on liberalization of abortion held in November of 1970. Indeed, the voters of Washington were the first people to whom so many fundamental political and philosophical questions were put in the form of one decisional act. Thucydides has Pericles tell us that future ages would marvel at the heights which Athenian civilization had attained and at the political institutions and public spiritedness by which the state...

The Influence of Temporal Group Identities on Goal-Pursuit

David Reinhard
In this paper, I examine the psychological and motivational consequences of highlighting connections between past and present generations of an in-group. I hypothesize that connecting the present generation to its collective past causes people to feel connected to something greater than themselves, intensifies motivation to invest in the group, and increases the desire to leave a legacy. I integrate previously unconnected literatures that examine temporal group identities and offer a framework for interpreting their psychological...

Providing early education will empower the patient with tools, resources, and knowledge to self-manage the disease. Purpose: The aim of this study was to determine if providing early self-management education will improve the awareness of chronic kidney disease and increase knowledge regarding the disease process in the primary care setting. Design: A quasi-experimental study was conducted...

Monitoring and Evaluating a Bioretention Filter Enhanced with Zero-Valent Iron and Biochar

Ryan Mahon
Stormwater has become an increasing point of concern in water pollution. Non-point source pollution caused by runoff is one of the largest polluters to waterways, such as the Chesapeake Bay. The EPA and DEQ have created Total Maximum Daily Loads (TMDLs) for the Bay watershed to protect it from high pollutant levels. To comply with state and local TMDLs, increased runoff treatment is necessary. An existing bioretention system in Charlottesville, Virginia, was enhanced with zero-valent...
