An Examination Of The Relationships Among Locus Of Control, Role Variables, And Perceived Job Satisfaction, Glenn Ellis Liddell

Dissertations

The relationship among locus of control, role conflict, role ambiguity and job satisfaction were examined for chief housing officers of member institutions of the Association of College and University Housing Officers-International with a resident population of under 1,000.

The literature review revealed that high levels of role conflict and ambiguity are related to low levels of job satisfaction and that locus of control affects perceived role conflict, role ambiguity and job satisfaction. Internals (those who believe their fate is controlled by themselves) experience less role conflict and ambiguity and more job satisfaction then do externals (those who believe their fate …

Mathematical Simulation Of Proteins Separation In A Packed Bed, Jing James Huang

Dissertations

The generalized adsorption models are developed to simulate the unsteady state mass transfer behavior in a packed column. Based on the nature of adsorbent particles, the adsorption models may be classified into two categories: (1) the surface adsorption model, (2) the pore diffusion model. In the first model, it is assumed that the internal diffusion is negligible, and the adsorption rate is determined by external diffusion and surface adsorption. In the second model, the effect of internal diffusion is considered as significant as that of external diffusion. For both models, the effect of axial dispersion in fluid phase is emphasized. …

Mathematical Modeling Of Carrier Mediated Mass Transfer Through Liquid Membrane Systems, Keng Chao Wang

Dissertations

Dispersed liquid membrane systems are double emulsion drops. Two immiscible phases are separated by a third phase which is immiscible with the other two phases. The liquid membrane systems were classified into three types: (1) carrier mediated mass transfer, (2) mass transfer with reaction in the receiving phase, (3) mass transfer without any reaction involved. Copper extraction, phenol removal and solvent extraction were used as typical examples for each type of the membrane systems in the derivation of their mathematical models. Models with or without the consideration of film resistances were developed and compared. The models developed in this study …

Mixing Effect On Chemical Reaction In Liquid Phase, Ming-Teh Hsu

Dissertations

Mathematical models for the mixing phenomenon are proposed in this study. First model deals Newtonian and non-Newtonian fluid without chemical reaction. The new terminology " degree of mixing " is define in this model for the time-dependency of mixing toward its completeness. The velocity profile and boundary conditions are given, then the degree of mixing can be calculated by the mathematical model. The degree of mixing is influenced by fluid motion and it is function of time.

Second model deals with first-order reaction effected by mixing. A mean fractional conversion is defined to investigate the rate of bhemical reaction. Results …

A Comparison Of Computer-Assisted Instruction And Traditional Instruction In Braille Transcription, Susan Kay Vlahas Ponchillia

Dissertations

The purpose of this study was to compare the teaching effectiveness of computer-assisted instruction (CAI) with the effectiveness of traditional instruction of braille transcription for sighted persons. Since the traditional method (TM) of teaching and learning braille transcription requires a great deal of time for both instructor and student, it was hoped that computer-assisted instruction would be as efficacious as the traditional method while shortening time requirements for instructor and student. A review of the literature revealed that computer-assisted instruction has been successfully used in teaching many subjects including languages, providing immediate feedback and reducing learning time. In studies where …

The Relationship Between Demographic Factors And Leader Behavior Of Department Chairpersons Of Colleges Of Education In Michigan, John H. Ortyoyande

Dissertations

The purpose of this study was to answer the following questions: (1) What is the relationship between demographic factors; namely, age, gender, educational background, experience, social status, marital status, siblings, career path, professional memberships and publications and leader behavior (measured on two dimensions: Initiating Structure and Consideration)? (2) Can one predict leader effectiveness of department chairpersons prior to their selection? (3) To what extent is there congruence between self-ratings of chairpersons and ratings of their observers? (4) How are chairpersons selected in some public colleges in Michigan?

The research population consisted of 18 chairpersons and 108 randomly selected faculty members …

Stimulus-Reinforcer And Response-Reinforcer Relationships In The Determination Of Response Latency, Bruce Edward Hesse

Dissertations

Response latency is measured from the onset of a stimulus to the onset of a response and is relevant to both respondent and operant control procedures. Previous research has shown response latency to be a sensitive operant dependent variable but the contribution of respondent influences was not known. The present experiment used pigeons, a two-key procedure and a two component FR schedule to study the respondent (stimulus-reinforcer) contributions to the determination of an ostensibly operant response latency. Stimuli associated with each FR component were displayed on one key (stimulus key) while responding for reinforcement was required on a second key …

Mental Health Status Of Malay Students At U.S. Colleges And Universities, Md. Shuaib Che Din

Dissertations

The basic premise of this study was that foreign students are faced with problems during much of their stay in the United States. It was the purpose of this study to determine the effects of everyday life strains on the mental health status of Malay students at U.S. colleges and universities. Specifically, this study looked at the relationships between the symptoms of psychiatric disorders of depression, psychological coping resources of self-esteem and self-mastery, and the background variables. Also this study attempted to determine the levels of depression, self-esteem, and self-mastery; the manifestation of the depressive symptoms according to the domains …

The Relationship Between Women's Levels Of Achievement And Self-Reported Characteristics Using The Bem Sex-Role Inventory, Sandra Kay Ragen

Dissertations

The purpose of the study was to examine the relationship between adult women's perceptions of their sex role and their level of achievement. Sex role was defined by the scores achieved on the Bem Sex-Role Inventory (BSRI), and achievement level was based on an index of education, work role, and salary. It was hypothesized that a significant relationship exists between levels of achievement and self-reported masculine (instrumental) and feminine (expressive) characteristics.

A random sample of 100 females was selected from membership roles (N = 600) in the Kalamazoo Network, Kalamazoo, Michigan, a high-achieving women's group. Seventy-five (75) usable returns provided …

Mathematical Modeling Of Unsteady State Photo-Polymerization, Rong-Fa Liang

Dissertations

Mathematical modeling of unsteady state photopolymerization in an isothermal batch reactor has been investigated. An analytical solution of the distribution of active polymers as a function of reaction time has been determined. It is verified that the quasi-stationary state approximation is valid in the photopolymerization process.

The free radical polymerization of styrene is forced periodically by on-off UV light regulation to the reactor. The effect of operating condition, the ratio of light-off period to light on/off period, on the polydispersity and molecular weight distribution are theoretically and numerically investigated. Significant broadening on molecular weight distribution can be obtained during the …

The Effects Of Pressure On The Kinetics And Mechanisms Of The Bod Reaction, Peter Sereico

Dissertations

The research was concerned with the kinetics and mechanisms of BOD reduction due to pressurization. The initial investigations involved attempts to reproduce and interpret the results of previous investigators. Thereafter, actual wastewater samples were pressurized and changes in the wastewater characteristics were analyzed and recorded. Based on the findings, possible mechanisms for creating the changes noted were proposed.

To test the mechanisms considered, samples of pure compounds were prepared and pressurized. The results of this analysis eliminated all of the mechanisms but the actual one. The mechanism responsible for changes in BOD profile under pressure conditions is the hydrolysis of …

Mathematical Modeling Of Distillation Operation From Non-Equilibrium Approach, Wen-Dow Pan

Dissertations

A new method for mathematical modeling of a distillation operation from non-equilibrium approach has been studied. The primary purpose of the study was to develop a model to simulate the mechanism of mass transfer between a continuous phase and the bubbles of a dispersed phase in a distillation column. The second major purpose of this work was to utilize and test the model of estimating the tray efficiency.

Distillation was considered to be purely a mass transfer process, where the less volatile component is transferred from vapor to liquid phase, and the more volatile component from liquid to vapor phase. …

Use Of An Optical Probe To Measure Bubble Characteristics In Gas Fluidized Beds, Thomas Tai-Pai Chu

Dissertations

A novel optical probe has been developed and used for on-line monitoring of the bubble characteristics in a three-dimensional gas fluidized bed. The probe sensor has a major dimension of 1.8 cm, and contains an LED and a photo-cell separated by a gap of 2.5 mm. Coupled with a non-inverting comparator circuit with hysteresis as a noise filter, the probe has been very effective in characterizing the size distribution, shape and velocity of gas bubbles.

A 96 liter rectangular fluidized bed was used, containing glass beads with a size fraction of 355μ to 250μ. Air was the fluidizing medium, with …

Public Universities And Societal Development – Application Of The Ideal Type Methodology In The Case Studies Of Addis Ababa University And Michigan State University, Solomon Wako

Dissertations

The role of higher education in societal development has been addressed by a number of scholars in various fields including sociology. Though these scholars virtually agree on the importance of university education, they have not identified the type of the university that facilitates the kind of societal development they advocate. Therefore, this study is concerned with the construction of a theoretical model of the ideal type university that will facilitate the conceptualization of societal development for Ethiopia and the USA. The study employs Weber's ideal type methodology which simply refers to the construction of certain elements of reality into logically …

A Comparative Study Of The Career Aspirations, Job Seeking Patterns, And Career Patterns Of Male And Female Doctoral Recipients In Educational Administration, Alice J. Hullhorst

Dissertations

There has been a dramatic increase in the number of women completing advanced degrees in education administration during the past decade. Yet, the number of women administrators has decreased during this same time period. The purpose of this study was to compare career aspirations, job seeking patterns, and career patterns of men and women doctorates in educational administration.

The sample consisted of 118 men and 118 women who received doctorates in educational administration or educational leadership from Mid-American Conference universities between 1976-1980. A mailed questionnaire was used to collect data. The 23 hypotheses were tested using a chi-square test or …
