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 …

Computer Science is concerned with the electronic manipulation of information. Continually increasing amounts of computer time are being expended on information that is not numeric. This is represented in part by modem computing requirements such as the block moves associated with context switching and virtual memory management, peripheral device communication, compilers, editors, word processors, databases, and text retrieval. This dissertation examines the traditional support of non-numeric information from a software, firmware, and hardware perspective and presents a coprocessor design to improve the performance of a set of non-numeric operations. Simple micro-coding of operations can provide a degree of performance improvement …

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 …

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 …

Sense Of Humor And Social Anxiety, James E. Fischer

Retrospective Theses and Dissertations

In utilizing humorous intervention within the psychotherapeutic milieu, researchers have indicated that there is a relationship between an individual's sense of humor and stressful emotions, specifically anxiety. However, the nature of this relationship is uncertain. While some scientists propose a direct relationship between humor and anxiety, others hypothesize an inverse relationship. This study was designed to investigate this relationship, hypothesizing that the greater an individual's sense of humor, the more likely the individual would experience anxiety in social situations. The subjects were 143 male and female undergraduates. These volunteers were administered the Situational Humor Response Questionnaire (SHRQ) and the Interaction …

Impulse-Response Of A Multiaperture Vision System Eyelet, Ron Driggers, Carl Halford, Roy Walters

Faculty Bibliography 1980s

Multiaperture vision systems are of interest in the area of robotic vision. A facsimile of the insect eye may be as useful for transmitting information to robotics as conventional cameras, which are analogous to the human eye. A physical model of one multiaperture vision system, the insect apposition ommatidia, has been successfully constructed. To provide an understanding of the multiaperture vision system, the impulse response of a single eyelet, or ommatidium, was developed. Experimental measurements of the impulse response were found to closely match theoretical results.

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 …

Employee Assistance Programs: The State Of The Art In Central Florida, W. Thomas Oldroyd

Retrospective Theses and Dissertations

A considerable amount of literature has been written on Employee Assistance Programs (EAPs), yet the research to date has not proven the effectiveness of such programs. Due to the confidential nature of EAPs, research data are difficult to find. Many elements make up an EAP. The hypothesis tested during this research is that companies incorporating what are considered by many to be the essential elements of EAPs will have more positive opinions of those elements and will save more money when compared to companies that do not have an EAP. The data were collected over a four-week period from 52 …
