The Feasibility Of Computerized Cognitive Testing As A Surrogate Measure For Assessment Center Performance, Leilani M. De Saram

Retrospective Theses and Dissertations

The use of microcomputerized cognitive testing of personnel has thus far been limited to military and environmental stressor applications. The investigation of such testing as a substitute for assessment center performance represents a novel application of this technology. An examination of the relationship between performance on a cognitive test battery and assessment center performance was conducted.

A battery of selected microcomputerized tests measuring cognitive constructs was administered to assessment center candidates in law enforcement occupations. Contrary to expectations, the computerized cognitive measurements did not exhibit significant correlations with assessment center performance measures. It was speculated that the two measures assessed …

A Case Study In Rumor Transmission Based On The Leo Frank Case, George Mark Jackson

Retrospective Theses and Dissertations

The purpose of this study was to examine the process of rumor transmission in an historical context. The basis was a case study of the Leo Frank incident. The editorials of Populist editor Tom Watson, written during Frank's appeal and commutation, were tested for emotional intensity. Significant findings tended to support the anxiety component of the Rosnow/Fine model for rumor transmission. The study was limited as there was no control condition without anxiety.

Effect Of Visual Reminder On The Ttr And Mlu-W Of Oral Hearing-Impaired Students During High/Scope Recall Sessions, Joan S. Kissel

Retrospective Theses and Dissertations

Language samples of sixteen oral hearing-impaired students, aged 3.8 to 10.6 years with a mean SRT average of 27dB, were taken during High/Scope recall sessions under two conditions: with visual reminder (a videotape replay of their session work-time) or without visual reminder (no videotape replay of their work-time). These language samples, taken over a three month period, were analyzed with SALT (Systematic Analysis of Language Transcripts) for flexibility (using TTR) and structure (using MLU-W), and for five other SALT analyses. In each of the seven SALT analyses, improvement was shown for both groups with a trend for greater improvement shown …

Women And Men : Do They Prefer Different Leaders?, Melanie A. B. Lee

Retrospective Theses and Dissertations

A sample of 13 female and 16 male managers from five different businesses completed modified versions of the Hersey/Blanchard Leader Behavior Analysis (LBA) questionnaires. The questionnaires consisted of 20 business-setting scenarios in which a leader must take some action. The managers were asked to choose the action that best described what their 11 ideal" leaders would do in each of the particular situations. The results confirmed the study's hypothesis that the 11 ideal 11 leader descriptions would not differ for the female and male managers. Subordinates of the sample managers completed 11 0ther 11 versions of the LBA, in which …

The Relationship Between Computer Experience And Anxiety In Computer Versus Paper-And-Pencil Administration Of The State Portion Of The State-Trait Anxiety Inventory, Timothy D. Orrell

Retrospective Theses and Dissertations

The effect of computer experience on state anxiety was investigated for both computer and paper-and-pencil administrations. It was hypothesized that, when assessed via computer, subjects having low computer experience would show significantly higher state anxiety scores than their computer experienced counterparts. Sixty undergraduate students were administered the State portion of the State-Trait Anxiety Inventory via paper-and-pencil (P-A-P) and computer (CRT) in counterbalanced design, with pretest levels of computer experience and trait anxiety being premeasured. Results indicated that there were no significant differences between the CRT, P-A-P, and trait anxiety groups. These findings reveal no significant difference between level of computer …

A Student Performance Evaluation Method For An Intelligent Simulation-Based Tutoring System, Camille Marie Dixon

Retrospective Theses and Dissertations

Intelligent simulation-based tutoring systems (ISTS) present intriguing and complex environments for the training of high performance skills. These skills involve the manipulation of objects within time and space constraints.

As with any tutoring system, there must exist a performance measurement methodology. Within an ISTS there is a module which functions as a tutor and a module which functions as a student modeler. These fundamental modules are required to make effective individualized tutoring decisions. However, each of these modules rely on information from a performance measurement system or evaluation system.

The objective of this research was to establish a performance evaluation …

Optimization Of Storm Sewer Construction Costs Using A Microcomputer Program, Dawn E. Fetter

Retrospective Theses and Dissertations

When designing a storm sewer system there is a material and labor cost trade-off between changing pipe diameter for a specific flowrate while keeping physical pipe slope constant, and changing physical pipe slope for the same flowrate while keeping the pipe diameter constant.

To calculate costs associated with every possible combination of pipe diameters and excavation depth to find the optimum design for a storm sewer network without the use of a computer would be a very cumbersome task indeed. In fact, a minimum cost solution may never be found.

This paper presents a microcomputer program which assists the engineer …

The Etiology Of Bulimia Nervosa From A Psychodynamic Socio-Cultural Perspective, Michael John Hryckowian

Retrospective Theses and Dissertations

The present research examined the etiology of bulimia nervosa from a psychodynamic perspective. The Eating Disorder Inventory (EDI) and Bern Sex Role Inventory (BSRI) were used to compare bulimics and controls on a number of personality dimensions including drive for thinness, body shape dissatisfaction, interoceptive awareness (one's lack of confidence in identifying emotions or visceral sensations) and sex role identification. Using the appropriate scales on the EDI, it was hypothesized that bulimics would demonstrate a higher drive for thinness and more body dissatisfaction than controls and that they would possess poorer interoceptive awareness than controls. In agreement with the dynamic …

A New Method For Broadband Surface Acoustic Wave Diffraction Analysis, Jacqueline Hanvey Hines

Retrospective Theses and Dissertations

This thesis describes an innovative technique for determining the impulse response of a SAW device including the effects of diffraction on both isotropic and anisotropic substrates. The approach presented is unique in that it determines the point-to-point impulse response for the isotropic case using the two-dimensional wave equation, and utilizes a double integral reduction technique to determine the tap-to-tap response, thereby significantly reducing the complexity of the calculations involved. An extension is then made to describe the impulse response of two cascaded transducers of arbitrary geometry, along with some simplifying cases. Previous attempts to model diffraction effects generally utilized either …

Parallel Parsing In A Multiprocessor Environment, Dilip Sarkar

Retrospective Theses and Dissertations

Parsing in a multiprocessor environment is considered. Two models for asynchronous bottom-up parallel parsing are presented. A method for estimating speedup in asynchronous bottom-up parallel parsing is developed, and it is used to estimate speedup obtainable by bottom-up parallel parsing of Pascal-like languages. It is found that bottom-up parallel parsing algorithms can attain a maximum speedup of 0 (L^1/2) with (L^1/2) processors, where L is the number of tokens in the string being parsed. Hence, bottom-up parallel parsing technique does not yield good speedup. A new parsing technique is proposed for parsing a class …

Automatically Generating Syntax-Directed Editors For Graphical Languages, Farahangiz Arefi

Retrospective Theses and Dissertations

This research is concerned with the automatic generation of syntax-directed editors for graphical programming languages. A specification technique that is used to uniformly define graphical languages along with their syntax-directed editors is developed. The novel aspect of this specification technique, called a general graph transformation system, is that the graphical languages are described by specifying a family of editing operations. In this manner, a language is defined as a dynamic object which, by applying different editing operations, changes from one form to another, each form representing a sentence of the language. In order to demonstrate this process, the language of …

Generating Multiple User Interfaces For Multiple Application Domains, Mahesh Hassomal Dodani

Retrospective Theses and Dissertations

This Ph.D. dissertation presents a classification scheme for User Interface Development Environments (UIDEs) based on the multiplicity of user interfaces and application domains that can be supported. The SISD, SIMD and MISD [S= Single, I= user Interface(s), M= Multiple, D= application Domain(s)] generator classes encompass most of the UIDEs described in the literature. A major goal of this research is to allow any user to develop a personalized interface for any interactive application, that is, the development of an MIMD UIDE.

Fundamental to the development of such a UIDE is the complete separation of the user interface component from the …

On K - Y - Insensitive Donimation, Teresa Haynes Rice

Retrospective Theses and Dissertations

A connected graph G is defined to be k-1-insensitive if the domination number 1(G) is unchanged when an arbitrary set of k edges is removed. The problem has been solved fork= 1. This Ph.D. dissertation focuses on finding extremal k-1-insensitive graphs on p nodes, fork~ 2. A graph is extremal if it has the minimum number of edges. Two subproblems are considered. The first, which has been solved completely, specifies that the same set of nodes dominates each graph obtained from G by removing k edges. The second requires only that the graph G be connected. This is a much …

A Relational Object-Oriented Management System And An Encapsulated Object-Oriented Programming System, Michael L. Nelson

Retrospective Theses and Dissertations

The purpose of the Relational Object-Oriented Management System (ROOMS) is to show that the relational database scheme is a viable approach for storing objectoriented data. ROOMS is designed so that it can be implemented in any object-oriented language with appropriate I/O commands, or added to any objectoriented database management system that allows userdefined collections of data. Various problems were encountered in developing ROOMS. While these problems have been solved, the best solution is to use the Encapsulated Object-Oriented Programming System (EOOPS) . EOOPS is based upon an inheritance scheme which preserves encapsulation. This encapsulated approach avoids the problems associated with …

Boundary Layer On A Continuous Flat Plate In Parallel Flow With Similar And Non-Similar Boundary Conditions, Vaughn H.M. Faber

Retrospective Theses and Dissertations

This thesis is a computational analysis of the incompressible laminar boundary layer on a continuous moving surface. The skin friction and heat transfer variations on a moving plate with similar and non-similar (constant) mass transfer at the wall are obtained for 210 cases for the similar boundary solution and 60 cases for the non-similar solution.

Both cases were solved numerically using the fourth order Runge-Kutta algorithm. For the non-similarity case, the local non-similarity method as described by Sparrow, Quack and Boerner was used. The analysis shows that the shear stress for both the similar and non-similar cases is higher when …

A Cellular Algorithm For Data Reduction Of Polygon Based Images, Robert James Caesar

Retrospective Theses and Dissertations

ABSTRACT The amount of information contained in an image is often much more than is necessary. Computer generated images will always be constrained by the computer's resources or the time allowed for generation. To reduce the quantity of data in a picture while preserving its apparent quality can require complex filtering of the image data. This paper presents an algorithm for reducing data in polygon based images, using different filtering techniques that take advantage of a priori knowledge as to the images' content. One technique uses a novel implementation of vertex elimination. By passing the image through a sequence of …
