The Playing Card’S Progress: A Brief History Of Cards And Card Games, Joyce Goggin

Reconstruction: Studies in Contemporary Culture

This article takes as its point of departure the fact that playing and tarot cards have generally been ignored as a topic for scholarly research, and suggests a number of reasons as to why this might be the case. While on the one hand cards are perceived as a trivial object, their long association with the occult and gambling further exacerbates the lack of serious interest taken in them. Moreover, because playing cards were imported into Europe from the East, they have been both directly and indirectly conceptualized as signifiers of oriental otherness and treated as a threat to the …

The Game's Afoot: Images Of Infinite Games In Samuel Delany's Trouble On Triton, Marc R. Zaldivar

Reconstruction: Studies in Contemporary Culture

Games are frequently used in speculative literature as a metaphor for real-world activities. In Trouble on Triton, Samuel Delany uses several sorts of games in order to explore complex systems of modeling and interrelationships between fiction and reality, extending a tradition in science fiction of placing games at the very center of social reality. Zaldivar's essay seeks to define some of the concepts of game theory that can be used to understand this complex novel and its representation of human social life. In particular, Zaldivar explores finite and infinite games and their uses within a deconstructive theoretical framework. A …

Digital Extensions And Performed Players: A Theoretical Model For The Video/Computer Game, Ben Fisler

Reconstruction: Studies in Contemporary Culture

Despite over twenty years of studies, scholars have yet to identify a productive theoretical model for the video game that does not depend on a fragmentary understanding of its form. Following Pierre Bourdieu's contention that the purpose of criticism is to understand cultural products as distinct scientific objects, and Marshall McLuhan's theory that the message and formative power of media are the media themselves, this study attempts to generate a foundational critical understanding of the video game. Building on the most lucrative intrinsic (such as David Myer's 1991 Computer Game Semiotics) and extrinsic (such as Jeffrey Goldstein's 1998 Immortal …

Cold War Games And Postwar Art, Claudia Mesch

Reconstruction: Studies in Contemporary Culture

During the Cold War both “superpowers” used games, particularly chess, in order to construct an ideology of complete conflict and irreconcilable division between East and West. This essay focuses on the broad cultural challenge to divisive Cold War zero-sum mentality issued by a number of artists—André Breton, Marcel Duchamp and Öyvind Fahlström, and Fluxus artists George Maciunas, George Brecht, Robert Watts, Takako Saito and Yoko Ono. These artists, in a second wave of game-focused art, returned to the concerns of surrealist art practice and to earlier cultural game theory. Even conceptual art production was impacted by the predetermined structure of …

In this work, design and implementation of control systems for a Maglev laboratory experiment and a Maglev vehicle under development at Old Dominion University are described. Both plants are modeled and simulated with consideration of issues associated with system non-linearity, structural flexibility and electromagnetic force modeling. Discussion concerning different control strategies, namely centralized and decentralized approaches are compared and contrasted in this work. Different types of electromagnetic non-linearities are considered and described to establish a convenient method for modeling …

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Gis And 3d Analysis Applied To Sea Turtle Mortalities And Navigation Channel Dredging, Bradley A. Shellito, Keith B. Lockwood

Virginia Journal of Science

Between 2000 and 2003 there were an increased number of documented sea turtle mortalities related to hopper dredging in the channels of the Chesapeake Bay. A pilot study was undertaken to create a bathymetric surface and three-dimensional model of the Cape Henry Channel using Geographic Information Systems (GIS) as a visualization tool to examine sea turtle mortalities in relation to the dredging. In Fall 2003, the US Army Corps of Engineers dredged the Thimble Shoals Federal Navigation Channel, and a more refined model was developed using this data. This project examines the growing concerns over sea turtle mortality rates and …

Sulcular Sulfide Monitoring: An Indicator Of Early Dental Plaque-Induced Gingival Disease, Aleksandra Pavolotskaya, Gayle Mccombs, Michele Darby, Kenneth Marinak, Naik N. Dayanand

Dental Hygiene Faculty Publications

Purpose. The purpose of this study was to evaluate the relationship between volatile sulfur compounds (VSC) and gingival health status and to determine if volatile sulfur compounds can detect early dental plaque-induced gingival disease. Methods. A split-mouth design with randomly selected quadrants of the mandibular arch enabled 39 participants to serve as their own controls. At baseline and at three subsequent appointments (days 7, 14, and 21) gingival inflammation (GI), bleeding on probing (BOP), and sulfide levels (SUL) were measured using the Gingival Index and the Diamond Probe/Perio 2000 System. For three weeks, participants refrained from brushing and flossing one …

Red And Black Tides: Quantitative Analysis Of Water-Leaving Radiance And Perceived Color For Phytoplankton, Colored Dissolved Organic Matter, And Suspended Sediments, Heidi M. Dierssen, Raphael M. Kudela, John P. Ryan, Richard C. Zimmerman

OES Faculty Publications

Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is not associated with any particular group of phytoplankton and is strongly dependent on the physiology of the human visual system. Red or brown surface waters can be produced by high concentrations of most types of algae, colored dissolved organic matter, or suspended sediment. Even though light reflected by red tides commonly peaks in the yellow spectral region (570–580 nm), human color perception requires consideration of the entire spectrum of light relative to receptors within the human eye. The color shift from green to red …

Variational Approach To The Volume Viscosity Of Fluids, Allan J. Zuckerwar, Robert L. Ash

Mechanical & Aerospace Engineering Faculty Publications

The variational principle of Hamilton is applied to develop an analytical formulation to describe the volume viscosity in fluids. The procedure described here differs from those used in the past in that a dissipative process is represented by the chemical affinity and progress variable (sometimes called "order parameter") of a reacting species. These state variables appear in the variational integral in two places: first, in the expression for the internal energy, and second, in a subsidiary condition accounting for the conservation of the reacting species. As a result of the variational procedure, two dissipative terms appear in the Navier-Stokes equation. …

A System Equivalence Related To Dulac's Extension Of Bendixson's Negative Theorem For Planar Dynamical Systems, Charlie H. Cooke

Mathematics & Statistics Faculty Publications

Bendixson's Theorem [H. Ricardo, A Modem Introduction to Differential Equations, Houghton-Mifflin, New York, Boston, 2003] is useful in proving the non-existence of periodic orbits for planar systems

dx/dt = F(x, y), dy/dt = G (x, y)

in a simply connected domain D, where F, G are continuously differentiable. From the work of Dulac [M. Kot, Elements of Mathematical Ecology, 2nd printing, University Press, Cambridge, 2003] one suspects that system (1) has periodic solutions if and only if the more general system

dx/d tau = B(x, y)F(x, y), dy/d tau = B(x, y)G(x, y)

does, which makes the subcase (1) more …

On The Existence Of Strong Solutions To Autonomous Differential Equations With Minimal Regularity, Charlie H. Cooke

Mathematics & Statistics Faculty Publications

For proving the existence and uniqueness of strong solutions to

dY/dt = F(Y), Y(0) = C,

the most quoted condition seen in elementary differential equations texts is that F(Y) and its first derivative be continuous. One wonders about the existence of a minimal regularity condition which allows unique strong solutions. In this note, a bizarre example is seen where F(Y) is not differentiable at an equilibrium solution; yet unique non-global strong solutions exist at each point, whereas global non-unique weak solutions are allowed. A characterizing theorem is obtained.

Template-Based Metadata Extraction For Heterogeneous Collection, Jianfeng Tang

Computer Science Theses & Dissertations

With the growth of the Internet and related tools, there has been a rapid growth of online resources. In particular, by using high-quality OCR (Optical Character Recognition) tools it has become easy to convert an existing corpus into digital form and make it available online. However, a number of organizations have legacy collections that lack metadata. The lack of metadata hampers not only the discovery and dispersion of these collections over the Web, but also their interoperability with other collections. Unfortunately, manual metadata creation is expensive and time-consuming for a large collection, and most existing automated metadata extraction approaches have …

Assimilating Non-Probabilistic Assessments Of The Estimation Of Uncertainty Bias In Expert Judgment Elicitation Using An Evidence Based Approach In High Consequence Conceptual Designs, Colin K. S. Barrows

Engineering Management & Systems Engineering Theses & Dissertations

One of the major challenges in conceptual designs of complex systems is the identification of uncertainty embedded in the information due to lack of historic data. This becomes of increased concern especially in high-risk industries. This document reports a developed methodology that allows for the cognitive bias, estimation of uncertainty, to be elucidated to improve the quality of elicited data. It consists of a comprehensive literature review that begins by defining a 'High Consequence Conceptual Engineering Environment' and identifies the high-risk industries in which these environments are found. It proceeds with a discussion that differentiates risk and uncertainty in decision-making …

An Examination Of Differences Between Occupational-Technical Student And Transfer Student Engagement At Small Community Colleges In Virginia, Janet T. Laughlin

Educational Leadership & Workforce Development Theses & Dissertations

This study examined the differences in levels of student engagement between occupational-technical students and transfer students in an attempt to gain insight into why so many students fail to attain their educational goals. Students' engagement or involvement with their educational institution and program of study is considered a major contributor to persistence and graduation. Research on student engagement as it relates to persisters and leavers includes the five student engagement variables benchmarked by the Community College Survey of Student Engagement (CCSSE): (a) active and collaborative learning, (b) student effort, (c) academic challenge, (d) student-faculty interaction, and (e) support for learners. …

Development Of A Nonlinear Estimator-Based Model Of Pilot Performance During Brownout Conditions, Karl Ulrich Schultz

Mechanical & Aerospace Engineering Theses & Dissertations

During conditions of visual occlusion, pilots are forced to rapidly adapt their scan to accommodate the new observable states via instruments rather than the visual environment. During this transition, the provision of aircraft state information via other than visual modalities improves pilot performance presumably through the increase in situational awareness provided immediately following the visual occlusion event.

The Tactile Situational Awareness System (TSAS) was developed to provide continuous position information to the pilot via tactile rather than visual means. However, as a low-resolution display, significant preprocessing of information is required to maximize utility of this new technology.

An increasing number of community college matriculants enter college needing remediation in mathematics. This study examined factors that may affect student retention and academic success in a developmental Algebra I course at a community college, including demographic variables, life demand variables, pre-enrollment academic characteristic, self-regulated learning characteristics, and instructional methodology.

The study ran for two consecutive semesters and included 154 participants. Self-report measures were used to gain demographic information and information about students' beliefs about math and their self-regulated learning characteristics at the beginning of the semester. An elementary algebra pre-test was administered at the beginning of the semester with …

Stability Analysis Of Hybrid Jump Linear Systems With Markov Inputs, Arturo Tejada Ruiz

Electrical & Computer Engineering Theses & Dissertations

In the past two decades, the number of applications that make use of supervisory algorithms to control complex continuous-time or discrete-time systems has increased steadily. Typical examples include air traffic management, digital control systems over networks, and flexible manufacturing systems. A common feature of these applications is the intermixing of the continuous dynamics of the controlled plant with the logical and discrete dynamics of the supervising algorithms. These so-called hybrid systems are the focus of much ongoing research. To improve the performance of these systems, it is important to analyze the interactions between the supervising algorithms and the plant. Few …

The plan is based on two cycles of assessment and evaluation, a short cycle of one year and a long term cycle of three years. …

Electron Scattering From High-Momentum Neutrons In Deuterium, A.V. Klimenko, S. E. Kuhn, H. Bagdasaryan, S. Bültmann, S. L. Careccia, K. V. Dharmawardane, Gail Dodge, G. Gavalian, N. Guler, C.E. Hyde-Wright, A. Klein, R. A. Niyazov, S. Tkachenko, L. B. Weinstein, Et Al., Clas Collaboration

Physics Faculty Publications

We report results from an experiment measuring the semiinclusive reaction ²H(e,e′p_s) in which the proton p_s is moving at a large angle relative to the momentum transfer. If we assume that the proton was a spectator to the reaction taking place on the neutron in deuterium, the initial state of that neutron can be inferred. This method, known as spectator tagging, can be used to study electron scattering from high-momentum (off-shell) neutrons in deuterium. The data were taken with a 5.765 GeV electron beam on a deuterium target in Jefferson Laboratory's Hall B, using the CEBAF …

Measurement Of The Deuteron Structure Function F₂ In The Resonance Region And Evaluation Of Its Moments, H. Bagdasaryan, S. Bültmann, K. V. Dharmawardane, G. E. Dodge, T. A. Forest, G. Gavalian, N.

Physics Faculty Publications

Inclusive electron scattering off the deuteron has been measured to extract the deuteron structure function F₂ with the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. The measurement covers the entire resonance region from the quasielastic peak up to the invariant mass of the final-state hadronic system W similar or equal to 2.7 GeV with four-momentum transfers Q² from 0.4 to 6 (GeV/c)². These data are complementary to previous measurements of the proton structure function F₂ and cover a similar two-dimensional region of Q² and Bjorken variable x. Determination of …

Growth Of Ge Quantum Dots On Si(100)-(2×1) By Pulsed Laser Deposition, M. S. Hegazy, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Self-assembled germanium quantum dots (QDs) were grown on Si(100)-(2×1) by pulsed laser deposition. In situ reflection-high energy electron diffraction (RHEED) and postdeposition atomic force microscopy are used to study the growth of the QDs. Several films of different thicknesses were grown at a substrate temperature of 400 °C using a Q-switched Nd:yttrium aluminum garnet laser (λ= 1064 nm, 40 ns pulse width, 23 J/cm ² fluence, and 10 Hz repetition rate). At low film thicknesses, hut clusters that are faceted by different planes, depending on their height, are observed after the completion of the wetting layer. With increasing film thickness, …

Melting And Solidification Study Of As-Deposited And Recrystallized Bi Thin Films, M. K. Zayed, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Melting and solidification of as-deposited and recrystallized Bi crystallites, deposited on highly oriented 002-graphite at 423 K, were studied using reflection high-energy electron diffraction (RHEED). Films with mean thickness between 1.5 and 33 ML (monolayers) were studied. Ex situ atomic force microscopy was used to study the morphology and the size distribution of the formed nanocrystals. The as-deposited films grew in the form of three-dimensional crystallites with different shapes and sizes, while those recrystallized from the melt were formed in nearly similar shapes but different sizes. The change in the RHEED pattern with temperature was used to probe the melting …

Part 3: Tunnel Vision: Traffic Congestion In Hampton Roads, Regional Studies Institute, Old Dominion University

State of the Region Reports: Hampton Roads

Traffic congestion already is bad in the region; we estimate the cost in 2006 to be $473 million, or $296 per person. If nothing is done to alleviate the situation, this cost will grow to $1.07 billion, or $608 per person in 2015. Our simulations also predict the speed of automobile commuters going through the Hampton Roads Bridge-Tunnel will fall to 7.2 mph in 2015.

Population Dynamics Model Of The Hard Clam, Mercenaria Mercenaria: Development Of The Age- And Length-Frequency Structure Of The Population, Eileen E. Hofmann, John M. Klinck, John N. Kraeuter, Eric N. Powell

CCPO Publications

An individual-based model was developed to simulate growth of the hard clam, Mercenaria mercenaria, in response to temperature, salinity and food supply conditions. Unique characteristics of the model are that: (1) length and tissue weight are related only by condition index, so that weight, up to a point, can vary independently of length, and (2) age is decoupled from length. Tissue weight changes result from the difference in assimilation and respiration. Changes in hard clam condition are determined from a standard length-weight relationship for average hard clam growth. Changes in hard clam length (growth) occur only when condition index is …

Understanding The Success And Failure Of Oyster Populations: Climatic Cycles And Perkinsus Marinus, Thomas M. Soniat, John M. Klinck, Eric N. Powell, Eileen E. Hofmann

CCPO Publications

Perkinsus (=Dermocystidium) marinus is a major cause of mortality in eastern oysters. Crassostrea virginica. Because initiation of infection and progression of disease are favored by high temperature and high salinity, we hypothesized that climatic cycles influence cycles of disease. Analyses of a 10-y time series of disease prevalence and intensity, chlorophyll a, suspended sediments, water temperature and salinity from a Louisiana site, using a wavelet technique, show a teleconnection between the El Nino-Southern Oscillation (ENSO) and oyster disease in the northern Gulf of Mexico. Salinity increases precede increased disease prevalence by several months. The changes in salinity that trigger changes …
