An Empirical Evaluation Of Specialized Law Reviews, Chris Guthrie, Tracey E. George

Vanderbilt Law School Faculty Publications

The sudden, rapid, and widespread increase in the number of specialized law reviews has attracted relatively little scholarly attention even though it is the most significant development in legal academic publishing in the second half of the twentieth century. As a consequence, there is a dearth of information about the proliferation, significance, and status of specialized reviews. In this Article, we attempt to fill this information gap by documenting the rise of the specialized review and by providing an empirical ranking of the top 100 specialized reviews.

Traits Of Instrumentality And Self-Concept As Related To Mathematical Ability In Pre-Adolescent Girls, Bridget Lee Toon

Student Work

This study examined whether the androgynous trait of instrumentality, (otherwise known as having an androgynous gender-type), and having a positive self-concept is related to higher mathematical ability in pre-adolescent girls in the seventh and eighth grades. Since participants were in both honors and average math classes, the additional variable of being in honors math versus regular math was also analyzed. There were 39 participants that were selected from Norris Middle School, which is in the Omaha Public School System. From these 39 participants, 18 were in honors math classes, while 21 were in regular math classes. The Piers-Harris Self-Concept scale …

Trust And Ethics In International Business Negotiations: A Cross-Cultural Analysis, Mohammad Niamat Elahee

Theses and Dissertations - UTB/UTPA

The growing interdependence in the global economic and political arena is resulting in accelerated growth in cross-national commercial relationships. Since some form of negotiation precedes most commercial activities and relationships, the topic of cross-cultural negotiation is of crucial importance to academicians, practitioners, and policy formulators. Despite its importance, research on cross-cultural business negotiation has not been very systematic and most of the empirical studies lack the explanatory power that is necessary for theory building. This study attempts to overcome this shortcoming by systematically linking different dimensions of national culture with different types of negotiation behavior.

This dissertation studies the relationship …

Nitrate Reductase Activity, Nitrate Uptake And Iodine Speciation In The Marine Environment, Chin-Chang Hung

OES Theses and Dissertations

The present method for the determination of new production (NP) by measuring the uptake of added ¹⁵NO₃^– suffers from a number of limitations. In an attempt to improve this situation, this research examined the possibility of estimating ¹⁵NO₃– uptake by measuring the activity of nitrate reductase (NRA). In addition, because it has long been suspected that the biological reduction of IO₃^– to I^– may be mediated by nitrate reductase (NR), this research investigated the ability of NR to catalyze the reduction of iodate to iodide.

An improved method for the determination …

Large Amplitude Pitching Of Supermaneuver Delta Wings Including Flow Control, Yahia A. Abdelhamid

Mechanical & Aerospace Engineering Theses & Dissertations

The unsteady, three-dimensional Navier-Stokes equations are solved to simulate and study the aerodynamic response of a delta wing undergoing large amplitude pitching motion up to 90° angle of attack. The primary model under consideration consists of a 76° swept, sharp-edged delta wing of zero thickness, initially at zero angle of attack. The freestream Mach number and Reynolds number are 0.3 and 0.45 × 106, respectively. The governing equations are solved time-accurately using the implicit, upwind, Roe flux-difference splitting, finite-volume scheme. Both laminar and turbulent flow solutions are investigated. In the laminar flow solutions, validation of the computational results is carried …

Evolving Neural Networks Applied To Predator-Evader Problem, Shivakumar Viswanathan, Ilker Ersoy, Filiz Bunyak, Cihan H. Dagli

Computer Science Faculty Research & Creative Works

The creation of strategies to meet abstract goals is an important behavior exhibited by natural organisms. A situation requiring the development of such strategies is the predator-evader problem. To study this problem, Khepera robots are chosen as the competing agents. Using computer simulations the evolution of the adaptive behavior is studied in a predator-evader interaction. A bilaterally symmetrical multilayer perceptron neural network architecture with evolvable weights is used to model the “brains” of the agents. Evolutionary programming is employed to evolve the predator for developing adaptive strategies to meet its goals. To study the effect of learning on evolution a …

A Blind Deconvolution Approach For Resolution Enhancement Of Near-Field Microwave Images, Ali Mohammad-Djafari, Nasser N. Qaddoumi, R. Zoughi

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper we propose a blind deconvolution method to enhance the resolution of images obtained by near-field microwave nondestructive techniques using an open ended rectangular waveguide probe. In fact, we model such images to be the result of a convolution of the real input images with a point spread function (PSF). This PSF depends mainly on the dimensions of the waveguide, the operating frequency, the nature of the object under test and standoff distance between the waveguide and the object. Unfortunately, it is very difficult to model this PSF from the physical data. For this reason, we consider the …

A Family Of Hierarchical Encoding Techniques For Image And Video Communications, Samah A. Senbel

Computer Science Theses & Dissertations

As the demand for image and video transmission and interactive multimedia applications continues to grow, scalable image and video compression that has robust behavior over unreliable channels are of increasing interest. These desktop applications require scalability as a main feature due to its heterogeneous nature, since participants in an interactive multimedia application have different needs and processing power. Also, the encoding and decoding algorithm complexity must be low due to the practical considerations of low-cost low-power receiver terminals. This requires image and video encoding techniques that jointly considers compression, scalability, robustness, and simplicity.

In this dissertation, we present a family …

The Relationship Between Vocabulary And Reading Comprehension In Junior High Aged Students With Learning Disabilities, Harvey Burkhour

Masters Theses

The purpose of this study was to investigate the relationship between the reading ability, particularly in the area of reading comprehension and the level of reading vocabulary possessed by junior high aged students with learning disabilities. Reading is a complex process involving the simultaneous integrated application of the four cuing systems: (a) graphophonic, (b) syntactic, (c) semantic, and (d) schematic. While most people learn to utilize these systems rather easily, this is not true for everyone. Failure to effectively employ any one or more of these cuing systems can spell disaster for the reader both in school and in many …

Observations And Interpretation Of Gravity Wave Induced Fluctuations In The O I (557.7 Nm) Airglow, G. Schubert, R. L. Walterscheid, Michael P. Hickey Ph.D., C. A. Tepley

Publications

Observations of fluctuations in the intensity and temperature of the O I (557.7 nm) airglow taken at Arecibo in 1989 are reported and interpreted on the assumption that they are caused by gravity waves propagating through the emission layer. The data give the magnitude of Krassovsky's ratio as 3.5 ± 2.2, at periods between about 5 and 10 hours. Comparison with theory shows that the gravity waves responsible for the measured airglow variations must have long wavelengths of several thousand kilometers. The observed phases of Krassovsky's ratio are in good agreement with theoretically predicted values at the long wavelengths and …

Traning Strategy Use And Its Effects On Working Memory Capacity, Jennifer Lynn Scott

Psychology Theses & Dissertations

Two experiments were conducted to examine whether strategy use affects the storage component of a working memory task. In Experiment 1, all 21 participants were given training to create stories from lists of to-be-remembered words (i.e., chaining) within a short-term memory task (i.e., including only a storage task). Short-term memory task performance and working memory span task performance were examined before and after training. Both short-term memory and working memory task performance improved from pretest to post-test. In Experiment 2, the same strategy training was given to 30 participants. In addition, another 30 participants were assigned to a control condition. …

Development And Application Of Adaptive Dynamic Grids For Wake Vortex/Ground Interaction, Ilker Emin Türkgeldi

Mechanical & Aerospace Engineering Theses & Dissertations

An adaptive and dynamic grid approach is developed for the numerical computations of wake vortex flow problems with ground interaction. The unnecessary grid points at the far field of the original, large, single zone grid are removed for computational efficiency. Next, the grid is modified into an adaptive one, where the fine core region keeps track of the vortices and can be split into two regions when the vortex separation distance exceeds a specified limit length. In the final step a multi zonal feature is added to this grid by means of two embedded grids placed at the vortex centers …

Newton Parameter Update Algorithm For Recurrent Neural Networks Applied To Adaptive System Identification And Control, Donald Allen Gates

Electrical & Computer Engineering Theses & Dissertations

This paper shows that the combination of a second-order neural network parameter update algorithm and internal network feedback can be effectively used for adaptive, nonlinear, dynamical system identification and control. Adaptive neural identification and control algorithms are typically utilized for real-time applications where the rate of adaptation is often critical. A fast, adaptive network parameter update algorithm is presented.

Simulation results show that this algorithm is capable of quickly identifying and adapting to changes in system parameters, making it feasible to use for real-time control and fault accommodation applications.

Jet Stability And Noise Computations Using Direct Numerical Simulation, Farouk Owis

Mechanical & Aerospace Engineering Theses & Dissertations

The computations of axisymmetric jet noise with symmetric disturbances are investigated using the direct numerical simulation of the unsteady compressible Navier-Stokes equations. High order accurate numerical schemes are employed for the solution of the governing equations. The investigation shows that MacCormack schemes with operator splitting and minimum dispersion error can be used to predict noise radiated from subsonic and supersonic jets with low and high Reynolds numbers. In addition, different kinds of nonreflecting boundary conditions are used at the inflow and outflow boundaries. These boundary conditions include characteristic boundary conditions, buffer domain technique and perfectly matching layer method. The results …

Investigation Of Resonant Photoemission In Gd With X-Ray Linear Dichroism, Shubhra R. Mishra, Thomas K. Cummins, George Daniel Waddill, W. J. Gammon, Gerrit V. Van Der Laan, Kyle W. Goodman, James G. Tobin

Physics Faculty Research & Creative Works

The constructive summing of direct and indirect channels above the absorption threshold of a core level can cause a massive increase in the emission cross section, leading to a phenomenon called "resonant photoemission." Using novel magnetic linear dichroism in angular distribution photoelectron spectroscopy experiments and theoretical simulations, we have probed the nature of the resonant photoemission process in Gd metal. It now appears that temporal matching as well as energy matching is a requirement for true resonant photoemission.
