Diverse sociology theoretical constructs serve as the lens to examine the evolution of two popular symbols of US culture in the last 20 years: yellow ribbons displayed as decoration and awareness ribbons worn as personal accoutrement. This research was motivated by society's weakened state of "collective consciousness," whereby shared beliefs and values have declined and some have completely disappeared, and sought to determine whether symbols will survive in a culture without commitment to the social. Invoking Christopher Lasch's Culture of Narcissism, Jean Baudrillard's Simulacra and Simulation, David Riesman's theory of other-directedness from The Lonely Crowd, and Stjepan Mestrovic's Postemotional Society, this work examined the significance of public displays of ribbons (whether on animate or inanimate objects), theorized why cer...
A new model for an adult human gastrointestinal tract (GIT) has been developed for use in internal dose estimations to the wall of the GIT and to the other organs and tissues of the body from radionuclides deposited in the lumenal contents of the five sections of the GIT. These sections were the esophagus, stomach, small intestine, upper large intestine, and the lower large intestine. The wall of each section was separated from its lumenal contents. Each wall was divided into many small regions so that the histologic and radiosensitive variations of the tissues across the wall could be distinguished. The characteristic parameters were determined based on the newest information available in the literature. Each of these sections except the stomach was subdivided into multiple subsections to include the spatiotemporal variations in the s...
Recent debates as to the place of Old South symbols and institutions in the South of the new millennium are evidence of a changing order in the South. I examine -- from a rhetorical perspective informed by Kenneth Burke's theory of identification and division -- four debates that have taken place in the South and/or about the South over roughly the past decade, 1995 to the present. In this decade, Southerners and interested others have debated such issues as 1) admitting women to the Virginia Military Institute and the Citadel; 2) integrating displays of public art in Richmond to feature Confederates and African Americans side by side; 3) continuing to fly the Confederate battle flag in public spaces such as the South Carolina Capitol or including it in the designs of state flags such as those of Georgia and Mississippi; and 4) allow...
Throughout the process industry, the conservation and allocation of mass and energy resources plays a pivotal role in the site wide optimization of a plant. Typically, raw materials are transformed into products, byproducts and wastes through pathways involving heating/cooling, pressure changes, mixing, reactions and separations. These pathways often require the addition or removal of energy from the system. The optimal management of such a system therefore requires conserving resources through the appropriate allocation of materials and energy. In a typical plant, there are both mass and energy objectives that require optimization. This dissertation will focus on optimizing the mass and energy resources present in a utility system. This will entail developing a novel framework of techniques to: target and design steam cogeneration n...
Resource variation and species interactions require organisms to respond behaviorally, physiologically, and morphologically within and among generations to compensate for spatial and temporal environmental variation. One successful evolutionary strategy to mitigate environmental variation is phenotypic plasticity: the production of alternative phenotypes in response to environmental variation. Phenotypic plasticity yields multiple characters that may enable organisms to better optimize phenotypic responses across environmental gradients. In this thesis, I trace the development of thought on phenotypic plasticity and present two empirical studies that implicate phenotypic plasticity in producing morphological variation in response to resource variation. The first empirical study addresses trophic plasticity, population divergence, a...
Hydrocarbon recovery from conventional reservoirs is decreasing and the need to produce oil cheaply from mature, marginal and unconventional reservoirs poses a big challenge to the industry today. Multilateral well technology can provide innovative solutions to these problems and prove to be the most likely tool to propel the industry in the next century. In this research we propose a new multilateral well architecture for more efficient and effective field drainage. We study the architecture from a reservoir engineering point of view and analyze the effect of various design parameters such as branch density and penetration extent of laterals on the performance of the proposed architecture for homogeneous reservoirs. We also analyze the performance in case of anisotropic reservoirs. The numerical simulation results show that the multi...
Phosphofructokinase from Bacillus stearothermophilus (BsPFK) is a homotetrameric enzyme with an average of one active site and one allosteric site per subunit. BsPFK is inhibited by phosphoenolpyruvate (PEP) and how this inhibitory signal is propagated throughout the enzyme is the main question we address through this investigation. By possessing a total of eight binding sites, a potential for twenty-eight total pair-wise allosteric interactions result within BsPFK, ten of which are unique. Of these ten interactions, four are heterotropic interactions, or interactions between unlike binding sites, while the remaining six interactions are homotropic interactions, or interactions between like binding sites. Thus, to address the question of how BsPFK is inhibited by PEP, each of these ten interactions needs to be quantified and their ...
Student affairs practitioners develop a variety of skills in order to serve students and the institutions in which they work. This research study used a newly developed instrument to assess the perceived performance of a variety of skills and the methods that student affairs professionals use to develop those skills.
The population included professional affiliates of Region III of the National Association of Student Personnel Administrators. Faculty members and those not practicing in student affairs were excluded from the surveyed population. The professional affiliates were identified as new professionals, mid-managers, and senior student affairs officers.
The instrument identified 72 skill statements in ten categories: leadership; student contact; communication; personnel management; fiscal management; professional development; res...
Automated detection of geological boundaries and determination of cyclic events controlling deposition can facilitate stratigraphic analysis and reservoir characterization. This study applies the wavelet transformation, a recent advance in signal analysis techniques, to interpret cyclicity, determine its controlling factors, and detect zone boundaries. We tested the cyclostratigraphic assessments using well log and core data from a well in a fluvio-eolian sequence in the Ormskirk Sandstone, Irish Sea. The boundary detection technique was tested using log data from 10 wells in the Apiay field, Colombia.
We processed the wavelet coefficients for each zone of the Ormskirk Formation and determined the wavelengths of the strongest cyclicities. Comparing these periodicities with Milankovitch cycles, we found a strong correspondence of the t...
This research combines a statistical tool called experimental design/response surface methodology with reservoir modeling and flow simulation for the purpose of reservoir characterization. Very often, it requires large number of reservoir simulation runs for identifying significant reservoir modeling parameters impacting flow response and for history matching. Experimental design/response surface (ED/RS) is a statistical technique, which allows a systematic approach for minimizing the number of simulation runs to meet the two objectives mentioned above. This methodology may be applied to synthetic and field cases using existing statistical software tools.
The application of ED/RS methodology for the purpose of reservoir characterization has been applied for two different objectives. The first objective is to address the uncertainties i...
