Updating Optimal Decisions Using Game Theory And Exploring Risk Behavior Through Response Surface Methodology, Jeremy D. Jordan
Updating Optimal Decisions Using Game Theory And Exploring Risk Behavior Through Response Surface Methodology, Jeremy D. Jordan
Theses and Dissertations
This thesis utilizes game theory within a framework for updating optimal decisions based on new information as it becomes available. Methodology is developed that allows a decision maker to change his perceived optimal policy based on available knowledge of the opponents strategy, where the opponent is a rational decision maker or a random component nature. Utility theory is applied to account for the different risk preferences of the decision makers. Furthermore, response surface methodology is used to explore good risk strategies for the decision maker to approach each situation with. The techniques are applied to a combat scenario, a football …
Computer Simulations Of Glyceraldehyde -3 -Phosphate Dehydrogenase Interactions With Actin And Fructose -1,6 -Bisphosphate Aldolase, And Substrate Binding Dynamics, Victor F. Waingeh
Computer Simulations Of Glyceraldehyde -3 -Phosphate Dehydrogenase Interactions With Actin And Fructose -1,6 -Bisphosphate Aldolase, And Substrate Binding Dynamics, Victor F. Waingeh
Theses and Dissertations
The association of glycolytic enzymes with cytoskeletal proteins such as actin is thought to be a structural basis for compartmentation of the glycolytic pathway. It is also suggested that such interactions bring glycolytic enzymes within close proximity to each other so that substrate transfer between sequential enzymes is faster. Brownian dynamics (BD) simulations were used to study the binding of glyceraldehydes-3-phosphate dehydrogenase (GAPDH) to actin and fructose- 1,6-bisphosphate aldolase (aldolase) in different species, and the dynamics of substrate binding. High-resolution three-dimensional models of the proteins used in the simulations were either obtained from X-ray structures or built by homology modeling. …
Stratification Of Southern Georgia Streams For Rapid Bioassessment Focusing On Differences In Structure And Function Of Black Water And Clear Water Streams, Salini Pradeep Pillai
Stratification Of Southern Georgia Streams For Rapid Bioassessment Focusing On Differences In Structure And Function Of Black Water And Clear Water Streams, Salini Pradeep Pillai
Theses and Dissertations
As part of a rapid bioassessment project for the state of Georgia, relatively unimpaired reference streams and impaired sites were sampled for biological, chemical and physical parameters, and macroinvertebrates were identified. The metrics, biological, physical and chemical metrics, were selected using Ecological Data Application System Version 3.3.2k (EDAS). Discrimination efficiency and correlations were performed to determine the best metrics that separated impaired streams from reference streams and later on to form the index of stream water quality. Principal components analysis of the selected metrics showed that some of the blackwater reference streams and clearwater reference streams are randomly placed over …
System For Collision Detection Between Deformable Models Built On Axis Aligned Bounding Boxes And Gpu Based Culling, David Owen Tuft
System For Collision Detection Between Deformable Models Built On Axis Aligned Bounding Boxes And Gpu Based Culling, David Owen Tuft
Theses and Dissertations
Collision detection between deforming models is a difficult problem for collision detection systems to handle. This problem is even more difficult when deformations are unconstrained, objects are in close proximity to one another, and when the entity count is high. We propose a method to perform collision detection between multiple deforming objects with unconstrained deformations that will give good results in close proximities. Currently no systems exist that achieve good performance on both unconstrained triangle level deformations and deformations that preserve edge connectivity. We propose a new system built as a combination of Graphics Processing Unit (GPU) based culling and …
Addressing Issues In The Detection Of Gene-Environment Interaction Through The Study Of Conduct Disorder, Elizabeth Prom-Wormley
Addressing Issues In The Detection Of Gene-Environment Interaction Through The Study Of Conduct Disorder, Elizabeth Prom-Wormley
Theses and Dissertations
This work addresses issues in the study of gene-environment interaction (GxE) through research of conduct disorder (CD) among adolescents and extends the recent report of significant GxE and subsequent replication studies. A sub-sample of 1,299 individual participants/649 twin pairs and their parents from the Virginia Twin Study of Adolescent and Behavioral Development was used for whom Monoamine Oxidase A (MAOA) genotype, diagnosis of CD, maternal antisocial personality symptoms, and household neglect were obtained. This dissertation (1) tested for GxE by gender using MAOA and childhood adversity using multiple approaches to CD measurement and model assessment, (2) determined whether other mechanisms …
Herbal Medications: Implications For The Operating Room, Tricia Marcuson
Herbal Medications: Implications For The Operating Room, Tricia Marcuson
Theses and Dissertations
US households have an increasing number of people using herbal medications as common self treatments. According to Hodges & Kam (2002), 32-37% of Americans have used herbal medications in the last year. Schmidt (2004) states that 1 in 3 Americans consume herbal products each year. Between 1990 and 1997, the use of herbal medicines increased 380% (Ernst, 2004). The interactions between herbal medications and anesthetic drugs become more important and meaningful due to the wide spread use. There are currently 15 million adults in the United States at risk for a potential adverse interaction with a prescription medication and an …
Techniques For Reclaiming Mined Lands With Native Plants, Maria Elena Melnechuk
Techniques For Reclaiming Mined Lands With Native Plants, Maria Elena Melnechuk
Theses and Dissertations
In this experiment I examined the role of mycorrhizae, seeding rate, and fertilizer in promoting growth of native plants at a reclaimed mine site in central Arkansas. Permanent field plots were established to examine effects of treatments on native plant cover, nonnative plant cover, and bare ground. By the final year of data collection, 18 native species had been newly established at the experimental site. Compared to plots without mycorrhizae, plots with mycorrhizae had significantly higher native plant cover in the first sampling year only. The addition of native seed was important—plots without added seed had significantly lower native plant …
Electronic Media And The Novice-Level Esl Textbook, Jacob Selz Brown
Electronic Media And The Novice-Level Esl Textbook, Jacob Selz Brown
Theses and Dissertations
The past decade had seen a re-evaluation in both foreign language, and English as a Second/Foreign Language, instruction methods due to the new technology available to aide in this instruction. While different institutions have access to different levels of technology, the adoption of basic technology for the classroom will eventually happen in the entire developed world. The purpose of this thesis is to wed the new technology available to a traditional textbook. It offers guided instruction to help a facilitator who may have never taught English as a Second/Foreign Language before, along with the actual electronic media needed to supplement …

The subjects of fear, archetypal symbolism, personal and collective histories were examined through research, archival evidence, video, sound, movement, and installation. reunion, examines not only the powers of personal and collective histories through the symbolic language of archetypes, but also how fear manifests and evolves through time. The culmination of this work was the creation of an installation within the Anderson Gallery at Virginia Commonwealth University. This Thesis was created through the use of Microsoft Word 2004.
The Effects Of Early Postnatal Pcp Administration On Performance In Locomotor Activity, Reference Memory, And Working Memory Tasks In C57bl/6 Mice, Alan L. Pehrson
The Effects Of Early Postnatal Pcp Administration On Performance In Locomotor Activity, Reference Memory, And Working Memory Tasks In C57bl/6 Mice, Alan L. Pehrson
Theses and Dissertations
There is a growing consensus, based on several converging lines of evidence, which suggests schizophrenia is the product of a developmental insult occurring in the late 2 nd or early 3 rd trimester. Additionally, it has been observed that adults who abuse the noncompetitive NMDA antagonist PCP present with symptoms that mimic schizophrenia, such as hallucinations, formal thought disorder, delusions, unstable or flattened affect, social withdrawal, and impaired cognition. Thus, several labs have attempted to use early postnatal PCP administration in rodents as a drug model of schizophrenia. The current study investigated the cognitive effects of early postnatal PCP administration …
Overbite Correction And Smile Esthetics, Kevin Erick Kelleher
Overbite Correction And Smile Esthetics, Kevin Erick Kelleher
Theses and Dissertations
The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate. Pre-treatment, post-overbite correction and post-treatment records were gathered from 32 patients who presented with deep overbite malocclusions to the Virginia Commonwealth University orthodontic clinic. Both groups of patients experienced reductions in overbite and maxillary incisor display as well as maxillary and mandibular incisor proclination and mandibular incisor occlusal movement during treatment. In the intrusion arch group, the center of resistance of …
Role Of Rok And Pkc In Permeabilized Rabbit Femoral Artery, Lyndsay Jacquelyn Clelland
Role Of Rok And Pkc In Permeabilized Rabbit Femoral Artery, Lyndsay Jacquelyn Clelland
Theses and Dissertations
Discoveries made with KCl-induced contractions have elucidated the more complex reactions involved in GPCRs signaling; once the mechanisms of smooth muscle Ca2+ sensitization and desensitization are fully understood, then the development of advanced treatments for vascular disorders such as hypertension, cerebral and coronary vasospasm, and vascular hyporeactivity following hemorrhagic shock may be possible. Studies have shown that KCl-induced contractions induce Ca2+-sensitization. Therefore, we tested the hypothesis that KCl induced Ca2+-sensitization is due to ROK activation by the increase in [Ca2+]i. To test this hypothesis, rabbit femoral arteries were permeabilized with 20µg/ml α-toxin and 1% Triton X-100 and subjected to different …

Toward A New Kinship Constellation, Nellie Helen Frances Appleby
Theses and Dissertations
This thesis attempts to elaborate on my artwork during my graduate studies, while contextualizing it within the framework of the art world and the works of other artists. A main project during this time was to minimize the singular interpretation and framing of a fine art photographic print, while expanding its possibilities of meaning through the addition of important ephemera and objects such as plants, drawings, moving imagery, conversation and the unknown.
