Self-Concept In Home-Schooling Children, John Wesley Taylor V

Dissertations

The home school appears to be in a renaissance. This national study sought to provide an empirical base upon which to formulate viable decisions regarding homeschooling children. The study considered homeschoolers in grades four through twelve. The randomized sample yielded 224 qualified participants.

Conclusions include the following:

1. The self-concept of the homeschoolers was significantly higher (p<.001) than that of the conventionally schooled population on all scales of the Piers-Harris Children's Self-Concept Scale. Half of the homeschoolers scored at or above the 91st percentile on the global scale.

2. Insofar as self-concept is a reflector of socialization, it appears that few homeschoolers are socially deprived.

3. The self-concept of the homeschoolers decreases significantly (p<.01) as age and grade level rise.

4. The factors of gender, number of siblings, locale of residence, prior conventional schooling, number of years …

A Comparative Study Of The Learning Styles Of Southeast Asian And American Caucasian College Students On Two Seventh-Day Adventist Campuses, Sally Lam-Phoon

Continuing Professional Education For Teachers And Its Relationship To Teacher Effectiveness, Gregory Allen Knoblock

Dissertations

In this study, the relationship between continuing education for the teacher and that teacher's effectiveness as measured by an achievement test and an evaluative measure completed by the teacher's students is investigated. The importance that number of hours, currentness, and subject area has upon any relationship with effectiveness, and the relationship between motivation for entry into and satisfaction with graduate/postgraduate work are also studied.

Data necessary to test these relationships were obtained from two sources: a survey of mathematics teachers in Macomb County, Michigan, and the results from two student instruments randomly administered to the classes of those teachers volunteering …

On Common Subgraphs, Hung Bin Zou

Dissertations

A greatest common (induced) subgraph of graphs G(,1) and G(,2) of equal size is a (an induced) common subgraph (without isolated vertices) of G(,1) and G(,2) having maximum size. For a given graph L, a graph G is locally L if the induced subgraph of the neighborhood of each vertex of G is isomorphic to L (L is called a common link). Several topics concerning these concepts are investigated in this dissertation. An historical background to these topics is given in Chapter I.

Chapter II is devoted to the topic on highly connected unique greatest common subgraphs of graphs. We …

An Industrial Ethanol Azeotropic Distillation Process : Modeling, Analysis, And Simulation, Harpreet Singh Chawla

Dissertations

A steady state process simulator with extensive capabilities was developed for the simulation of process plants involving non-ideal multicomponent systems. A comprehensive stand alone program was developed to represent process systems encountering three phases. A computer program was also developed to handle simultaneous regression of vapor-liquid and liquid-liquid equilibria data to estimate the liquid phase activity coefficients via a global set of parameters for the ethanol azeotropic distillation process, using benzene as the entrainer.

An industrial ethanol azeotropic distillation process has been simulated using the developed process simulator (PROSIM). A study of the azeotropic column's aqueous ethanol feed composition reveals …

Ternary Ion Exchange In Fixed Beds : Equilibrium And Dynamics, David W. H. Roth

Dissertations

A model was developed to simulate ion exchange within fixed beds for ternary systems. Models of the fluid phase material balance, phase equilibria, and diffusion of ions through the film and within the resin phase incorporated the latest advances in ion exchange theory. The separate model elements were combined after testing into an overall general model. Non-linear regression support programs were developed to estimate equilibrium parameters and resin phase diffusion coefficients.

A computer program was developed to estimate axial dispersion coefficients from experimental data. General correlations derived from literature sources were tested, and axial dispersion terms were included in the …

A Study Of The Relationship Between High School Graduation Requirements And Student A.C.T. Assessment Scores In Public High Schools In The State Of Michigan, William M. Pritchard

Dissertations

The literature has pointed toward changes in high school curriculum as a contributor to the decline of standardized test scores during the 1960's and 1970's. During the past few years, many schools have increased graduation requirements in various subject areas in an effort to increase learning on the part of students. The purpose of this study was to investigate the effect of the number of years of required study in various subject areas on student achievement.

The population that was studied included all public high schools in the State of Michigan. Two hundred thirty-eight schools were sampled from the population, …

The Relationship Between Nonsupervisory Employees' Self-Assessment Of Their Supervisory Skills And The Amount Of Satisfaction They Believe They Would Receive From Being A Supervisor, Arthur W. Hoffman

Dissertations

This descriptive study investigated the relationship between perceived supervisory effectiveness (competence) and perceived supervisory satisfaction for nonsupervisory professional-technical employees who may aspire to supervisory positions. The study participants are employees of a large industrial company engaged in the engineering and manufacturing of diversified products for the automotive industry. Specifically, the study attempted to (a) collect employee selfassessment data regarding the employee's perceived supervisory job effectiveness and perceived job satisfaction, (b) determine whether a relationship existed between perceived supervisory effectiveness and satisfaction, and (c) determine if the employee's age and educational level were influencing factors.

In order to investigate the relationship …

Personality Predictors Of Academic Success In Underachieving First Year College Students, Carolyn Wilson-Garrison

Dissertations

In this study, the role of nonintellective variables as predictors of academic success in underachieving first year college students was explored. Traditional predictors of college grades, high school grade point average and standardized scores on the American College Testing examination (ACT), were also examined.

The purpose of this study was to assess whether college grades at the end of the first year would differ according to underachieving students' personality styles, expressed concerns, and behavioral correlates thereby offering the possibility that such nonintellective factors may be useful in the prediction of grades.

The sample was a randomly selected group of eighty-seven …

Beyond Contingency Theory: Environment, Structure, And Administrator's Coping Ability In The Public Sector, Shyu-Tu Lee

Dissertations

In the last two decades, organizational-environment contingency theory has attracted much attention. A great deal of research has been done on investigating the impact of environment on organizations, suggesting the appropriate design of organizational structure. In recent years, organizational theorists have moved to investigate proactive approaches to organizational environments.

Most empirical studies, however, have been conducted in the private sector. In order to transfer the knowledge to the public sector, it is necessary to investigate whether public organizations are also subjected to environmental influence and how public administrators interact with the environment.

This study investigated the following three questions: (1) …

Investigation Of Pre-Detection Signal Processing Of Pseudonoise Communication Signals In The Presence Of Additive White Gaussian Noise And Cw And Bursty Interference, Israel Mayk

Dissertations

By comparison to conventional communication systems, spread-spectrum systems are known to be less affected by interference because of their large dimensionality in signal space. Nevertheless, significant performance degradation is experienced when large interference exists in a few or even one signal coordinates. In this case, interference reduction techniques are also known to provide additional processing gain. A novel class of pseudonoise (PN) invariant algorithms is derived to reduce the impact of interference and restore much of the structure of PN signals received in the presence of interference and noise. A PN signal received by a pre-detection signal process (PDSP) implementing …

Kinetic Modeling Of A Laminar-Flow Reactor, Shih-Hsin Chang

Dissertations

The laminar-flow reactor considering radial dispersion for a species incurring first-order homogeneous (bulk) and heterogeneous (wall) chemical reactions was mathematically modeled. The equation was solved both analytically, and by the Crank-Nicolson finite-difference technique.

The response surface method was used to obtain the optimum values of the two rate constants. The optimum values interact because the wall and bulk reactions proceed in parallel. Varied reactor diameters serve to decouple the bulk and wall reactions to locate the true values of the rate constants.

Four dimensionless variables were defined and used to characterize the reacting system. In addition, their values were shown …

The Effect Of A Higher Order Pole On The Optimum Design Of Minimum Threshold Phase Locked Detectors, Bernard Zivotofsky

Dissertations

The phase lockedloop is widely used as an FM demodulator known as a phaselocked detector (PLD). It is particularly useful in the detection of weak signals because lower threshold is possible with a PLD than with a conventional limiter discriminator. An enhanced version PLD known as an extended range phaselocked detector (ERPLD) is capable of further threshold reduction. The most popular PLD is a second order type I system employing a loop filter having one real pole and one real zero.

One implementation of an ERPLD calls for the addition of a differentiator to the standard loop filter which replaces …
