Effect Of Computer Graphics Use On Student Understanding Of Calculus Concepts, Charlene E. Beckmann

Dissertations

Student understanding of selected calculus concepts as developed through use of a Cartesian coordinate graphical representation system were investigated. Subjects (N = 163) enrolled in first-semester calculus sections at Western Michigan University participated in one of four treatment conditions: Graphics (G), exposure to a computer-graphically-developed conceptual course; Graphics Plus (G+), exposure to the same course as G subjects plus provision of computer graphics software and related supplemental assignments; Standard 1 (S1), exposure to a graphically-developed, conceptual course; and Standard 2 (S2), exposure to a traditional skill-oriented course.

Two investigations were undertaken. In Investigation 1, comparisons were made between G and …

The Psychological Needs Of Sex Offenders Of Children As Measured By The Personality Research Form, Shirley Anne Miller

Dissertations

Major contributors in the field of child sexual abuse have agreed that sex offenders who sexually abuse children are not primarily motivated by sexual desire and have proposed that the simultaneous satisfaction of a number of psychological needs is the prominent motivation of sex offenders of children. Few attempts have been made to empirically validate the clinical and theoretical impressions regarding the psychological needs of this group using psychological measures designed to assess needs or motives.

The purpose of this study was to investigate to what extent the assumptions about the psychological needs of sex offenders of children would be …

Intuition In Decision Making By Human Service Administrators, Judith Huber Halseth

Dissertations

The phenomenon of intuition includes insights and hunches, as well as the ability to pick up clues and to see patterns. The role of intuition in interpersonal relationships, in problem solving and decision making, and in creativity makes it an important cognitive faculty. As a complement to more systematic and deductive decision making, intuition provides creative insights, especially when people consciously acknowledge intuition.

This study focused on the experience of intuition as reported by 25 administrators in human service organizations. In face-to-face interviews, the 10 women and 15 men who were known to use intuition were asked open-ended questions about …

An Analogue Of Science, Michael Albert Minervini

Dissertations

There is no science of human behavior, not even an incipient one. The popular conception of applied behavior analysis as a genuine principle-driven technology is mostly an illusion. Two sorts of evidence support this conclusion. The first is an ever widening split between the field's basic and applied realms. The second, thus far unacknowledged, is that when the concepts of operant and respondent conditioning are extended to human behavior, they are often rendered as no more than metaphors. These metaphors are not confined to casual discourse or even to interpretation. In fact, they are the prevailing form of extension in …

Applied Thermoplastic Screw Plastication Theory: Industry Acceptance And Implications For Plastics Processing Education, Paul V. Engelmann

Dissertations

Rapid expansion of the thermoplastics processing industry has increased the need for plastics education and training. Screw plastication is the major method of melting plastics in order to mold or extrude them into useful products. Thus, information about the role of plastication is needed to provide guidance for plastics education and training.

This study sought confirmation of suspected differences existing in the amount of knowledge personnel have about thermoplastic screw plastication, dependent upon: (a) the type of plastics process used, and (b) their job classifications. Furthermore, the study collected data in three additional areas: (1) the extent to which persons …

Effectiveness Of Employee Participation Groups In A Manufacturing Company, John F. Blamy

Dissertations

This case study investigated the short term effectiveness of Quality of Work Life participation groups in a Midwest manufacturing division of a major worldwide automotive corporation. Six traditional procedural measures were used to evaluate performance. These measures of performance were: employee attendance, written grievances, scrap produced, quality audits, customer complaints, and productivity.

Six hypotheses were formulated for this study: (1) Employees in departments with employee participation groups will improve their attendance more than employees in departments that do not have employee participation groups. (2) Employees in departments with employee participation groups will decrease the number of formal grievances more than …

Gas-Phase Reactions Of Methylene Chloride And Methylene Chloride-Trichloroethylene Mixture With Methane In Tubular Flow Reactor And Atmospheric Pressure, Javad Tavakoli-Attar

Dissertations

Reactions of methylene chloride diluted in methane and Argon and a mixture of methylene chloride + trichloroethylene diluted in methane and argon are studied in three flow reactors of different surface to volume ratios 4, 10.5, and 16 mm ID , atmospheric pressure and over a temperature range of 750-1000 °C. Experiments were conducted isothermally, ±5 °C over central 80% of oven length using a three zone oven. Argon was added as a diluent in order to limit carbon (s) formation. The concentration ratios of methylene chloride/methane/argon and methylene chloride/trichloroethylene/methane/argon was held constant at 1:4:10 and 1:1:40:40 respectively, throughout the …

An Evaluation Of An Intervention Program For Juvenile Probationers, Kevin I. Minor

Dissertations

Although the efficacy of correctional rehabilitation was questioned during the early 1970s, recent research has demonstrated that certain intervention programs, when implemented under appropriate conditions, are effective in reducing illegal behavior. The objective of this research was to evaluate the effectiveness of a court-based intervention for juvenile probationers.

The program was developed on the basis of caseworkers' assessments of youths' problems and needs. The theoretical perspective underlying the intervention consisted of a joint combination of critical, social control, and differential association theories. A major implication of theory is that the juvenile court's capacity to facilitate informal social control should be …

Effects Of Task Difficulty, Performance Consequence, And Social Interaction On Physiological Reactivity In Post-Coronary Patients, A. Janelle Maldonado

Dissertations

Three experiments were performed to determine the effects of three task variables and Type A behavior pattern on physiological reactivity to time-limited math and anagram tasks. In the first experiment, ten post-coronary patients performed time-limited computer tasks under two performance consequence conditions: Point Reward or presentation of an Auditory Blast combined with two task difficulty conditions (40% and 60% difficult). The findings of Experiment 1 indicated that while the tasks did produce levels of physiological reactivity comparable to those observed in the literature, there were no significant main effects for either variable for any of the five measures. A significant …

Construct Validation Of The Family Of Origin Scale: A Factor Analysis, Omar L. Mangrum

Dissertations

The major purpose of this two-part study was to contribute to the body of knowledge concerned with the construct validity of the Family of Origin Scale (FOS). The issues of construct and discriminative validity were specifically addressed. The first phase was an attempt to empirically establish the underlying factor structure of the Family of Origin Scale (FOS) through factor analytic techniques. The analysis utilized data collected from a previously studied population (i.e., college students) and a demographically different population (i.e., prison inmates). Results from this study indicate that the FOS appears to measure at least seven distinct factors/constructs, four of …

The Effects Of Using Print Media In Teaching Critical Thinking Skills To Adult Students, Gloria Jean Mccormick

Dissertations

The purpose of this research was to investigate the effectiveness of an educational program in which print media were employed to teach critical thinking skills to adult education students. The major problem of this research was whether or not adult students, who lack a high school diploma, show greater improvement in critical thinking if they participate in a critical thinking skills program using print media, than if they do not. Adult education students in three suburban school districts of Macomb County, Michigan were the subjects of this study.

The methodology used in this study was a non-randomized control group, prettest-posttest …

Stimulus Overselectivity: An Investigation Of Determinants, Margaret T. Mcglinchey

Dissertations

Stimulus overselectivity refers to a phenomenon in which, after discrimination training with a multiple component stimulus, behavior fails to come under the control of all of the components of the stimulus. After a screening process based on past research, a group of children with specific learning disabilities was categorized into one of two groups: overselective and non-overselective. Both groups were exposed to training and testing for generalization. All children in both groups evidenced "stimulus overselectivity" during these tests for generalization. Generalization training subsequently reduced stimulus overselectivity for all students. There were few differences between the two groups. The results suggest …

Relationship Of Quality Circles In Nursing To Leadership, Job Satisfaction, Patient Care, And Cost Containment, Shirley A. Weiglein

Dissertations

The use of quality circles in nursing has been widely espoused in nursing literature as a concept that enhances participatory leadership, promotes job satisfaction, improves the quality of patient care and contributes to cost containment. This study was conducted to examine the relationship between the use of quality circles in nursing units and leadership, job satisfaction, the quality of patient care and cost containment.

Quality circle and non-quality circle units in two midwest hospitals were used for data collection. Staff nurses only were asked to complete the survey. A total of 126 of the possible 295 staff nurses in the …

Assessment Of Autonomic Regulation Of Heart Rate Variability, Shaw-Jyh Shin

Dissertations

Complex demodulation, accompanied by the techniques of interpolation, detrending and zero-phase-shift lowpass filtering were used to examine the effect of both divisions of the autonomic nervous system (sympathetic and parasympathetic) on heart rate by analyzing the heart rate variability signal from dogs under two different classical conditionings: CS+ and CS-, which cause different dynamic pattern changes in the autonomic nervous system to regulate the heart rate.

Unlike power spectral analysis, complex demodulation gives results in the time domain and shows the variation of amplitude and phase over time at a given frequency. The variation of phase indicates the frequency deviation …

Naturalistic Inquiry: An Appropriate Method For Evaluating Customer Training A Case Study Of A Computer System Value-Added Reseller, Barbara Coulter Broderick Edd
