All subjects were assessed for fatigue, workload, and boredom proneness. Subjects were then randomly assigned to conditions based upon fragrance and instructional set. One group of subjects was given Peppermint enhanced air and the other was given unscented air. Half of the subjects in each group were told that the fragrance or air would help their performance, while the other subjects were told nothing about the effects …

Comparison Of System Identification Techniques For The Dexterous Orbital Servicing System (Doss), Allan Terrence Morris

Electrical & Computer Engineering Theses & Dissertations

The major contribution of system identification is the development of analytical models of a system. Many identification techniques can adequately describe the input and output map. One of the challenges of these techniques is to correctly infer from the measured data the characteristics of the individual, contributing components producing a more accurate system model.

In this thesis linear, dynamic, multivariable state-space models for three joints of the Dexterous Orbital Servicing System (DOSS) are identified. DOSS is a representative space station manipulator at the NASA Langley Research Center. The dynamic models of the manipulator will first be estimated by applying nonparametric …

The Association Between Perceived Family Support And Psychological Well-Being In Infertile Couples, Linda Marquardt Mintle

Health Services Research Dissertations

A correlational research design utilizing a cross-sectional survey methodology was used to investigate the association between perceived family support and psychological well-being in infertile couples. Family stress theory and the construct of boundary ambiguity were conceptual frameworks applied to the developmental family life cycle. Respondents were 35 married infertile couples with primary infertility recruited from a private For-profit infertility clinic located in Virginia Beach, Virginia. Responses on the Moos and Moos (1984) Family Environment Scale and from the SCL-90-R developed by Derogatis (1977) measured perceived family support and psychological distress respectively. Major findings indicated that infertile couples rated their families …

A Bio-Cybernetic System For Regulating Operator Engagement In An Adaptively Automated, Multi-Task Flight Environment, Lawrence J. Prinzel Iii

Psychology Theses & Dissertations

A bio-cybemetic, closed-loop system was validated for use in an adaptively automated environment. Subjects were asked to perform either one task or three tasks from the MAT battery. EEG was continuously sampled while they performed the task and an EEG index was derived (20 beta/alpha + theta). The system made allocation decisions based upon the level of operator engagement as determined by the EEG index. The NASA-TLX was administered after each trial. The results of the study demonstrated that it was possible to moderate an operator's level of engagement through a closed-loop system driven by the operator's EEG. It also …

Names As Insults Among Middle School Students, Susan M. De Veer

English Theses & Dissertations

The following is a study of playful and insulting name-calling among suburban and rural public middle school males and females in grades six through eight in Tidewater, Virginia. Little is known about the effects of name-calling on self-esteem. Students were asked to rate the comfort level of the names they reported their friends called them. They were also asked to list their favorite television programs, films, and music videos to determine what influence, if any, the media has on name-calling. The 135 participating male and female students completed an anonymous survey administered by their teachers during home bell.

The collected …

Attentional Processing Of Visual Stimuli: What Makes A Face A Face?, Samuel L. Chapman

Psychology Theses & Dissertations

Reaction time (RT) and accuracy have been used to investigate the manner in which humans process visual stimuli for many years. Some researchers have found evidence of serial processing (e.g., Sternberg, 1969a) while others have shown that some visual stimuli are processed in parallel (e.g., Neisser, 1963). There have been very few studies investigating the processing of schematic faces with respect to RT and accuracy. The present study investigates the mechanisms associated with the recognition of schematic faces with respect to RT and accuracy.

Forty-two Old Dominion University students were shown a target face for ten seconds and were then …

Conjunctive Decisions In A Paper-And-Pencil Task, Tracy A. Bean

Psychology Theses & Dissertations

Many situations can have a significant effect on response time. Some situations affecting response time require union decisions - decisions based on the 'or' rule. The Hick-Hyman law, as well as Sternberg's linear relationship, are based on union decisions. Most situations in the real world, however, are based on intersection or 'conjunctive' decisions - decisions based on the 'and' rule. The relationship between conjunctive decisions and reaction time is examined in the present research. One question this study attempted to answer is whether there is a functional relationship between mean response time and display size.

The study consisted of 139 …

Hardiness And Sensation Seeking As Potential Moderating Variables In The Stress-Illness Relationship, William N. Campbell Jr.

Psychology Theses & Dissertations

One hundred and fifteen undergraduate psychology students participated in a study designed primarily to investigate the personality styles characterized by "hardiness" and "sensation seeking" as potential moderators in the stress illness relationship. Subjects completed inventories measuring life-event stress, perceived stress, and illness experienced during the previous year, as well as questionnaires measuring hardiness, sensation seeking, and maladjustment. Correlation analysis revealed significant positive relationships between life-event stress and illness and perceived stress and illness as well as a significant negative relationship between hardiness and maladjustment.

Multiple regression analyses showed that life-event stress, perceived stress, and the two measures used together significantly …

Patient Satisfaction Among Users Of The After Hours Program, Helen L. Larocco

Community & Environmental Health Theses & Dissertations

The problem of increasing health care costs and decreasing access to health care services is a major crisis in the U.S. today. One factor contributing to the rising cost of health care is the inappropriate use of emergency rooms, (ERs). In response to escalating costs a local health care corporation implemented a telephone triage program called the After Hours Program, (AHP). The goal of the program was to reduce inappropriate utilization of emergency rooms, and to educate patients to recognize and treat specific health problems independently, i.e., home treatment.

A program evaluation was completed in which different dimensions of patient …

Demonstration Of A Method For The Development Of A Team Classification System, Ann Marie Yanushefski

Psychology Theses & Dissertations

The purpose of this research was to demonstrate an approach to developing a system for classifying teams. A classification system is important for formulating theories, generating hypotheses, and especially as an aid in generalizing results from one setting to another. Although a number of classifications can be found in the team literature, each was developed in a rational rather than an empirical manner. As an alternative, an empirically derived classification system based on objective, empirical data was considered an improvement. The development of this type of system was the objective of the present study.

The Sundstrom and Altman (1989) classification …

Generalization Metrics For Neural Modeling Applications In System Identification, Denise M. Reeves

Electrical & Computer Engineering Theses & Dissertations

In this thesis a procedure to design multilayer feedforward networks for system identification with good prediction properties is presented. Central to the design procedure is a means to characterize the prediction capabilities of various trained neural networks. Such knowledge will allow for the identification of the best network design. For system identification purposes, a "good" model is one that is good at predicting, In particular, a good model is one that produces small prediction errors when applied to a set of cross-validation data. We formulate and implement a criterion function designed to measure the size of a trained neural network's …

The purpose of the research was to collect evidence regarding the effectiveness of this full-integration program. The results were as follows: (1) Reading and math achievement scores were not affected by the presence of an SPD student in the classroom except for in grade 4 where apparently math achievement was affected adversely. (2) Fourth graders in classes with a fully-integrated SPD student had more positive attitudes about persons with disabilities than students in the control …

Development Of A K-Correction Factor For The Mmpi-A, Jody Jacobson Alperin

Psychology Theses & Dissertations

In 1992, the Minnesota Multiphasic Personality Inventory - Adolescent (MMPI-A) was developed to meet the unique experiences and needs of adolescents. Despite evidence that adolescents often demonstrate response biases in taking the MMPI-A, currently there is no method to systematically "correct" for the effect of test-taking attitude on profile configuration with this age group. The K-correction factor has been widely used to correct for defensiveness or underreporting of symptomatology on the MMPI among adult respondents, although results of cross-validation research on the effectiveness of the K-correction factor have been inconclusive. The present study derived age-appropriate K-weights to determine the degree …

The Effects Of Aerobic Exercise On State And Trait Body Image And Physical Fitness Among College Women, Sherri L. Hensley

Theses and Dissertations in Urban Services - Urban Education

Cumulative evidence shows body dissatisfaction is a salient problem among women, and is linked to various psychological disorders and disturbances. While numerous perspectives regarding the negative body-image phenomenon exist, one area of scientific inquiry is the relationship between physical exercise and body image. With the current sociocultural emphasis on physical fitness and attractiveness, the effects of exercise on body image warrants serious consideration. The present investigation compared 57 women who participated in a 13-week aerobic exercise program to 29 sedentary control women on the following variables: state and trait body image, cardiorespiratory fitness, and body composition. The exercising women were …

Stephen Crane And "The Subtle Brotherhood Of Men", Christian Robert Weisser

English Theses & Dissertations

The purpose of this study is to examine the development of the works of Stephen Crane. Most critical studies define his philosophy strictly within the boundaries of Naturalism. A close examination of his novels and short stories shows a development towards a more melioristic view of mankind, one which endorses the value of brotherhood and group relations. Based on certain biographical, philosophical and cultural factors, Crane's work emerges as progressively more and more concerned with the possibility of effective human solidarity.

The Student Movement At Old Dominion: 1964-1970, Patrick Joseph Pané

History Theses & Dissertations

Old Dominion College, located in Norfolk, Virginia, experienced student unrest during the 1960s. Students at Old Dominion, like their counterparts throughout the country, challenged the university's authority and protested the war in Vietnam. This thesis will examine the student movement at Old Dominion College (which became Old Dominion University in 1969) from 1964 to 1970 and how the reactions of presidents Lewis W. Webb, Jr. and James L. Bugg, Jr. influenced student protest from 1964 to 1970. Lewis Webb, chief executive of the college from 1946-1969, tried to limit the movement's impact on campus. His policies resulted in conflicts over …

Out Of The Air: The Role Of Communications Intelligence In The Strategic Bombing Campaign Against The German Oil Industry And Transportation System In World War Ii, Darrell Nolen

History Theses & Dissertations

During World War II communications intelligence (ULTRA) was used to evaluate the effectiveness of the Allied strategic bombing campaign against the German oil industry and transportation system. In the case of the oil campaign communications intelligence provided confirmation of serious damage inflicted on the German war economy. This conformed nicely to the prewar American doctrine of precision daylight bombardment of critical nodes of an enemy industrial system. The intention of this policy was to cause the collapse of the enemy's military capability. The campaign against the German transportation system did not fit into this doctrinal framework as precisely; consequently, it …

The noncognitive variables were character type, temperament type/preference for learning style, and the Sedlacek Noncognitive Questionnaire …

Self-Esteem, Sense Of Community, And Participation In Organized Sports: A Study Of Rural High School Students On Virginia's Eastern Shore, Michele K. Lee

Sociology & Criminal Justice Theses & Dissertations

Using 1995 Survey data collected from high school students on Virginia's Eastern Shore, this study investigates how rural adolescents view themselves and their communities, and specifically how sports participation may affect self-esteem and sense of community. Adolescents, faced with a transition period between high school and adulthood, must begin to make choices such as attending college or technical school, entering the workforce, and/or moving away from their home communities. These choices are particularly important to the Eastern Shore because its economic vitality is in decline and its social vitality is hard hit by out-migration. Analyses of data from Northampton County …

Presidential Philosophies And American Foreign Policy: From The Long Telegram To The New Look, John R. Moore

History Theses & Dissertations

American foreign policy often undergoes alteration as presidential administrations change. After World War II president Harry S. Truman and President Dwight D. Eisenhower both implemented a foreign policy aimed at containing the Soviet Union, but the philosophical underpinnings of their foreign policies differed greatly. While the demands of partisan and international politics account for some of this difference, the impact on foreign policy of the two men's personalities deserves attention and investigation. In other words, how did the individual backgrounds, personal beliefs and world views of Truman and Eisenhower dictate their approach to foreign policy? The source used in this …

The Relationship Between Machiavellianism, Self-Monitoring, And Adaptiveness To The Performance Of Real Estate Sales Professionals, Dianne Broman Eppler

Theses and Dissertations in Business Administration

The focus of sales management is on insuring the success of the corporation by selling its goods or services. The most significant impact on the firm's success is the ability of the sales force to perform. Research to determine what makes a successful salesperson is extensive; however, the results are inconsistent and disappointing. In light of the significant financial impact the sales force has on the firm, additional research that identifies determinants of sales success is necessary.

The purpose of this dissertation was to examine the relationships between personal characteristics and sales performance. Specifically, Machiavellianism, self-monitoring, and adaptiveness were hypothesized …

A Comparison Of The Utilization Of Health Services In The Presence Or Absence Of Prescriptive Drug Insurance In A Managed Care Environment, Martha Groblewski

Health Services Research Dissertations

The Transference Of Traditional American Indian Oral Narratives Into Contemporary Literature, Barbara A. Baisley

English Theses & Dissertations

This thesis will examine Native American oral narratives and determine what influence western culture has had on the written recording of these stories. By examining traditional literature, I will analyze a trickster myth in order to establish Native American literary patterns. I will then examine Henry Schoolcraft's translations of Chippewa oral narratives and determine what is characteristic of Native American oral narratives and what alterations he made in order to market these narratives to an audience deeply entrenched in western literature.

I will also distinguish between Native American narratives translated into English and English narratives that contain an Native American …

No Other Track: Russell Hoban And The Literary Pilgrim, Eric G. Waggoner

English Theses & Dissertations

This study will examine the novels of Russell Hoban, an American-born writer living and working in London, and their consistent engagement of the idea of pilgrimage: the spiritual and geographical travel towards a particular goal as found in early Christian writing, as well as extant writings of other religions and cultures. After briefly tracing the social and literary history of the pilgrimage, I will examine each of Hoban's novels with an eye towards their secular revision of the pilgrimage motif, a revision which nonetheless retains a measure of spirituality.

Toward A More Functional Analysis Of Aggression, Robert A. Gable, Jo M. Hendrickson, Gary M. Sasso

Communication Disorders & Special Education Faculty Publications

Given the substantial and oftentimes irreversible human loss resulting from aggressive acts, the need for systematic, treatment-linked assessment of aggression in school-aged children and youth cannot be overstated. Based upon recent research, the authors provide a broadly framed model for the functional analysis of aggression in school-age children and youth. Our model incorporates multi-modal data collection and data triangulation to generate credible hypotheses regarding the function(s) of aggression. Three primary data sources—record review and interviews, naturalistic observation, and analogue assessment—form the cornerstone of the model. Key features of our approach to the assessment of aggression include operational definition(s) of target …

Southern Africa And The Themes Of Madness: Novels By Doris Lessing, Bessie Head, And Nadine Gordimer, Nancy Topping Bazin

English Faculty Publications

However different their lives, Doris Lessing, Bessie Head, and Nadine Gordimer share the common heritage of having grown up in southern Africa. All three were profoundly affected by that experience. Their responses to the colonialist, racist, and sexist attitudes that permeated their lives have determined, to a major extent. the nature of their fiction. Their novels reflect the grotesque situations and bizarre human relationships created by prejudice, injustice, and the desire to dominate. These three authors focus on the mad nature of this social and political situation in southern Africa. In their works, dystopian and utopian visions of the future …

Comparing Traditional Statistical Models With Neural Network Models: The Case Of The Relation Of Human Performance Factors To The Outcomes Of Military Combat, William Oliver Hedgepeth

Engineering Management & Systems Engineering Theses & Dissertations

Statistics and neural networks are analytical methods used to learn about observed experience. Both the statistician and neural network researcher develop and analyze data sets, draw relevant conclusions, and validate the conclusions. They also share in the challenge of creating accurate predictions of future events with noisy data.

Both analytical methods are investigated. This is accomplished by examining the veridicality of both with real system data. The real system used in this project is a database of 400 years of historical military combat. The relationships among the variables represented in this database are recognized as being hypercomplex and nonlinear.

The …
