An Examination Of Self-Efficacy In Master’S Level Counselor Trainees, Matthew G. Rushlau

Dissertations

This research is an investigation into changes in individuals’ belief of self-efficacy as they advanced through master’s-level counselor training. Differences were examined between reported levels of beliefs of self-efficacy for a group of 30 master’s students involved in counselor practicum training and 31 master’s students involved in basic counseling coursework. Participants completed the Counselor Self-Estimate Inventory (COSE) (Larson et al., 1992) at the beginning and end of an academic semester. Data generated by the COSE included an overall score on beliefs of counselor self-efficacy along with five subscale scores of various aspects of counseling, consisting of Micro-Skills, Process, Difficult Client …

The Relationship Of Reading Recovery Teachers' Efficacy To Length Of Service And School System Support, M. Louise Moon

Dissertations

Existing research results directly relate teachers’ efficacy to student outcomes and to continuing staff development and school context; however, little work has been done to investigate these relationships for Reading Recovery teachers. Reading Recovery (RR) is an early intervention program designed to assist first grade children who are having difficulty learning to read and write. This program requires ongoing staff development and an implementation plan designed to provide appropriate school context; therefore, survey data were collected from Reading Recovery teachers to study relationships between teacher efficacy and (a) their length of service in Reading Recovery and (b) support for RR …

A Resource Allocation Mechanism Based On Cost Function Synthesis In Complex Systems, Carlos C. Amaro

Dissertations

While the management of resources in computer systems can greatly impact the usefulness and integrity of the system, finding an optimal solution to the management problem is unfortunately NP hard. Adding to the complexity, today's 'modern' systems - such as in multimedia, medical, and military systems - may be, and often are, comprised of interacting real and non-real-time components. In addition, these systems can be driven by a host of non-functional objectives – often differing not only in nature, importance, and form, but also in dimensional units and range, and themselves interacting in complex ways. We refer to systems exhibiting …

Microwave Heating Of Fluid/Solid Layers : A Study Of Hydrodynamic Stability And Melting Front Propagation, John Gilchrist

Dissertations

In this work we study the effects of externally induced heating on the dynamics of fluid layers, and materials composed of two phases separated by a thermally driven moving front. One novel aspect of our study is in the nature of the external source, which is provided by the action of microwaves acting on dielectric materials. The main challenge is to model and solve systems of differential equations, which couple fluid dynamical motions (the Navie- Stokes equations for nonisothermal flows) and electromagnetic wave propagation (governed by Maxwell's equations).

When an electromagnetic wave impinges on a material, energy is generated within …

A Folder Organization Model For Information Systems : Exploring Its Architectural Expressive Power And Predicate-Based Filing, Simon Doong

Dissertations

This dissertation presents an Internal Folder Organization (I-ORG) which supplements the architectural deficiencies of the existing model - the User Folder Organization (U-ORG), to electronically model a person's filing system in the modern office environment. An I-ORG folder organization gives a logical representation of how documents of the same or different kinds are related and grouped into folders based on predefined premises. Our model is represented by a Rooted Direct Acyclic Graph (RDAG). Each node in the graph represents a folder; and folders are related by "subfolder relationship" (for capturing the "and" relation) and "virtual-folder relationship" (for capturing the "or" …

A Graph Based Process Model Measurement Framework Using Scheduling Theory, Gary Guang-Li Mou

Dissertations

Software development processes, as a means of ensuring software quality and productivity, have been widely accepted within the software development community; software process modeling, on the other hand, continues to be a subject of interest in the research community. Even with organizations that have achieved higher SEI maturity levels, processes are by and large described in documents and reinforced as guidelines or laws governing software development activities. The lack of industry-wide adaptation of software process modeling as part of development activities can be attributed to two major reasons: lack of forecast power in the (software) process modeling and lack of …

Automatic Analysis Of Electronic Drawings Using Neural Network, Yi Shi

Dissertations

Neural network technique has been found to be a powerful tool in pattern recognition. It captures associations or discovers regularities with a set of patterns, where the types, number of variables or diversity of the data are very great, the relationships between variables are vaguely understood, or the relationships are difficult to describe adequately with conventional approaches.

In this dissertation, which is related to the research and the system design aiming at recognizing the digital gate symbols and characters in electronic drawings, we have proposed: (1) A modified Kohonen neural network with a shift-invariant capability in pattern recognition; (2) An …

Influence Of Psychiatric Diagnostic Training On Counseling Students’ Development Of A Model-For-Helping And Professional Identity, Jerry E. Mclaughlin

Dissertations

Over the years, numerous proposals have been made in the counselor education (CE) literature about what counseling philosophy can best lead the profession to a distinctive professional identity (Bauman & Waldo, 1998; Fong & Lease, 1994; Guterman, 1994). An issue in this debate is whether psychiatric diagnostic training forms a part of a counseling philosophy (i.e., model-for-helping) and professional identity that is more focused on client psychopathology than on normal developmental issues. This study explored how training and experience in psychiatric diagnostic categories (PDCs) influenced counselors’ development of their counseling philosophy and professional identity.

Focus-group interviews were held at four …

The main area of interest is the study of Auger decay in atoms utilizing the process known as the resonance Auger effect, where an inner shell electron is excited to an unfilled orbital followed by the ejection of an Auger electron. The measurements in this thesis were performed by using the high resolution Atomic, Molecular and Optical Physics undulator beam line, which utilizes a spherical grating monochromator at the Advanced Light Source at …

A Computer/Tutorial System Compared With A Workbook/Tutorial System For Presenting Instructional Material To At-Risk Elementary School Students, Vincent O. Hodge

Dissertations

Two different ways of presenting instructional material and reacting to students’ responses were compared. One, taking advantage of several features of multimedia instruction involved a desktop computer and various computer-presented consequences of correct and incorrect responses (largely chosen by the student). The other consisted in presenting the same instructional materials (the SRA primary curriculum) in a workbook form with tutors' comments and praise as the main form of response consequence. The two methods were compared with respect to various measures of student and system performance, including student accuracy (percent correct responses), types of errors, amount of correct response repetition (over-responding), …

The Effects Of Counselor Skills Training On Levels Of Counselor Cognitive Complexity, David K. Duys

Dissertations

This study measured the impact of an intensive counseling skills training course on levels of cognitive complexity in novice counselors. Graduate level counseling students were assessed at the beginning of a basic counseling skills training course and again at the end of the course by obtaining written responses to a stimulus questionnaire. A control group was recruited consisting of other graduate counseling students who were taking other courses during the same time interval and who were not exposed to the basic counseling skills course. Participants in the control group were tested using the same instrument and their scores were compared …

Laterality Of The Perception Of Computer Presented Written Sexual Words By Right-Handed Males And Females, Randall W. Stewart

Dissertations

The right hemisphere of males has been shown to possess a greater capacity for accurate perception of emotional non-verbal material (pictures) than the left hemisphere. The same is true for females, but with a smaller difference between the two hemispheres. Some previous research has partially confirmed these relationships using tachistoscopic presentation of emotional words. The present study, using briefly exposed computerpresented sexual words, compared perception accuracy with respect to a sexuality rating of clearly sexual and clearly non-sexual words, in the right versus the left visual field, and with males versus females. As with previous research using verbal stimuli, the …

The Relationship Between Organizational Culture And The Practice Of Program Evaluation In Human Service Organizations, Lorraine Marais

Dissertations

There are many obstacles for human service organizations in evaluating programs. Some of these barriers are the difficulty in defining human behavior and the change that needs to be evaluated, human service programs that take a long time to show results, agency capacity to do evaluation, and cost (Young, Hollister, Hodgkinson, & Associates, 1993). Another subtle yet powerful influence on the practice of evaluation in nonprofit organizations may be organizational culture (Schein, 1990). If an organization is going to employ self-evaluation, an organizational culture may be needed that will support such efforts. This study was designed to assess the relationship …

A Kierkegaardian Understanding Of Self And Society: An Existential Sociology, Chris L. Jakway

Dissertations

In examining the history and development of existential sociology, it becomes clear that in its initial phases it was not intended to oppose traditional sociological research, but to complement it. I intend to show that the contemporary chasm between the methodologies can be narrowed with a reconsideration of their common roots in the work of G.H. Mead and the symbolic interactionists. Existential sociologists today offer a practical synthesis that combines that theoretical heritage with philosophic ontology dating back to the writings of Soren Kierkegaard.

My conceptual goal is reveal how the existential philosophy of Kierkegaard, while not irrational or solipsistic, …

Preparation For The Gre, Corina Groeger

Dissertations

The present research consisted of two empirical studies and a literature review. The first study was a systematic replication of the studies by Miller, Goodyear-Orwart, and Malott (1996) and Vunovich and Malott (1997). Fourteen undergraduate students and one graduate student participated in four intensive, extensive, structured Graduate Record Examination (GRE) preparation courses that met for seven weeks and lasted between 99 and 140 hours. The courses offered a monetary reward for students who met a minimum of 92% for attendance and participation during the course. The results of this study showed statistically significant mean improvements of 145 points for the …

Electron Emission Following The Interaction Of Slow Highly Charged Ions With Solids, Joseph W. Mcdonald

Dissertations

The interaction of highly-charged ions with surfaces involves many excitation processes of the surface atoms and the bulk material. One such process, the emission of electrons from surfaces due to the potential energy of the incident ions has been studied. The experimental results presented here confirm that the majority of electrons emitted as a result of highly-charged ions interacting with a solid surface have energies of about 20 eV. Auger processes contribute a smaller fraction of the total emitted electrons with increasing Z o f the projectile. This contribution to the total electron emission yield is found to be less …

The Effects Of Writing Assignments On Second-Semester Calculus Students' Understanding Of The Limit Concept, Melanie A. Wahlberg

Dissertations

The purpose of this study was to determine the impact of writing assignments on second-semester calculus students’ understanding of the limit concept, using both qualitative and quantitative techniques. The study involved two sections of second semester calculus (n = 37, 34) at Western Michigan University during the fall semester of 1997.

The treatment group completed six writing tasks focusing on the mathematical concept of limit. These conceptually-oriented writing assignments replaced some of the problem sets that the instructor would have normally assigned. The control group did not engage in writing tasks but handed in problem sets more frequently than the …

Disruption Of The Discriminative Stimulus Effects Of (+)-3, 4-Methylenedioxymethamphetamine (Mdma) By (± )-Mdma Neurotoxicity: Protection By Fluoxetine, Thomas B. Virden Iii

Dissertations

It is well established that repeated, high doses of 3, 4-methylenedioxymethamphetamine (MDMA) result in the long-term depletion of serotonin levels and destruction of serotonergic terminals in various locations in the brains of a variety of species. Further, it is also well known that concomitant injections of the serotonin reuptake inhibitor, fluoxetine, prevents this deterioration. It has recently been noted that such MDMA neurotoxicity disrupts stimulus control in rats trained to discriminate MDMA from saline in a drug discrimination procedure (Schechter, 1991a).

In order to extend Schechter's findings to the optical isomers of MDMA and to explore the potential of fluoxetine …

The Comparison Of Selection-Based And Topography-Based Verbal Behavior Across Populations, Carl T. Sundberg

Dissertations

Michael (1985) distinguished between selection-based (SB) and topography-based (TB) verbal behavior. Several studies comparing the ease of learning the two systems have shown conflicting results. The data indicate that subjects with fewer lower verbal skills have done better with TB systems (subjects with developmental disabilities in studies by Hodges & Schwethelm, 1984; Sundberg & Sundberg, 1990; Weirmanski, 1984; Wraikat, 1991; Wraikat, Sundberg, & Michael, 1991; and the bottom half of subjects in Cresson, 1994). The higher functioning subjects have done better (or have not shown a difference) with SB systems. (Bristow & Fristoe, 1984; Stratton , 1992; Tan, Bredin, Poison, …

Fostering Reflective Thinking In First-Semester Calculus Students, Pamela Crawford

Dissertations

This study focuses on the fostering of reflective thinking in students in a reform calculus course through completion of homework assignments incorporating reflective tasks, and the effect of these assignments on student understandings of calculus and conceptions of mathematics. The study, conducted in Fall 1997, involved two sections of first-semester calculus at a large midwestern university and used quantitative (n = 25, 18) and qualitative (n = 7) techniques.

Homework assignments incorporating reflective tasks included asking students to compare and contrast textbook ideas; to write about how obstacles were overcome as they attempted exercises; to develop concept maps organizing and …

Analytical And Experimental Study Of Investment Casting With Laser Stereolithography Models, Wen-Long Yao

Dissertations

This dissertation presents an analytical and experimental investigation of ceramic shell cracking during the burnout process in investment casting with internally webbed laser stereolithography (SLA) patterns. Included in the consideration are the cracking temperature of the ceramic shell, the web link buckling temperature, and the glass transition temperature of the epoxy resin. The hypothesis is that shell cracking will occur when the cracking temperature is lower than the glass transition temperature and the web buckling temperature.

An analytical and experimental study has been conducted, with the cross-sectional area, the span length of the web structure, and the shell thickness being …

Removal Of Volatile Organic Compound (Voc) Vapors In Biotrickling Filters : Process Modeling And Validation With Chlorinated Aromatic Compounds, Christos J. Mpanias

Dissertations

This study dealt with the removal of vapors of volatile organic compounds from airstreams in biotrickling filters (BTFs). A detailed general model was developed for describing the process under steady-state conditions. The model accounts for mass transfer between phases (air, liquid, biofilm) and biodegradation of pollutants in the biofilm. It also accounts for potential kinetic interactions among pollutants as well as potential process limitations by oxygen availability.

The general model was experimentally validated using mono-chlorobenzene (m-CB) and ortho-dichlorobenzene (o-DCB) as model compounds either alone or in mixture with each other. Before BTF experiments were undertaken, a systematic kinetic study was …

Robust Fuzzyclustering For Object Recognition And Classification Of Relational Data, Sumit Sen

Dissertations

Prototype based fuzzy clustering algorithms have unique ability to partition the data while detecting multiple clusters simultaneously. However since real data is often contaminated with noise, the clustering methods need to be made robust to be useful in practice. This dissertation focuses on robust detection of multiple clusters from noisy range images for object recognition. Dave's noise clustering (NC) method has been shown to make prototype-based fuzzy clustering techniques robust. In this work, NC is generalized and the new NC membership is shown to be a product of fuzzy c-means (FCM) membership and robust M-estimator weight (or possibilistic membership). Thus …

Performance Improvements In Wireless Cdma Communications Utilizing Adaptive Antenna Arrays, Weichen Ye

Dissertations

This dissertation studies applications of adaptive antenna arrays and space-time adaptive processing (STAP) in wireless code-division multiple-access (CDMA) communications. The work addresses three aspects of the CDMA communications problems: (I) near-far resistance, (2) reverse link, (3) forward link. In each case, adaptive arrays are applied and their performance is investigated.

The near-far effect is a well known problem which affects the reverse link of CDMA communication systems. The near-far resistance of STAP is analyzed for two processing methods: maximal ratio combining and optimum combining. It. is shown that while maximal ratio combining is not near-far resistant, optimum combining is near-far …

Being Alone: The Experience Of Elderly Homebound Females, Sharon Davis Burt Dnsc, Msn, Rn

Dissertations

Elderly women comprise one of the fastest growing segments of the population in the United States. This growth is due in large part to increasing longevity, and a woman's life expectancy has now reached 79 years. However, along with those added years comes an increase in morbidity and a greater likelihood of living alone. This study describes the life experience of a specific group of elderly women, those who are homebound and living alone. When elderly women are included in research, the same combination of descriptors used for the participants in this study has not been incorporated. Consequently, while much …

The Journey Through Perspective Transformation: Learning Nursing Theory, Judith R. Heggie Dnsc, Ms, Rn

Dissertations

Through the use of grounded theory, educational methods most useful for nurses to achieve a perspective transformation, as exemplified by learning nursing theory were examined. Perspective transformation is a theory originally developed by Mezirow (1978) in a study of older women returning to college for additional education. Mezirow defined perspective transformation as the alteration or change of meaning perspectives. Perspective transformation in an individual can be compared to a paradigm change within a scientific community. Within the nursing literature on perspective transformation, most articles related to the perspective transformation needed for nurses to learn to use nursing theory as the …

The Experience Of Decision-Making Among Telephone Advice/Triage Nurses, Ann Mayo Dnsc, Msn, Rn

Dissertations

The role of the telephone advice/triage nurse is both complex and demanding. All decisions are made while assessing patients without seeing or touching patients. In addition, the role is often developed to decrease health care costs which can be perceived by nurses as being in conflict with their nursing beliefs. The ambiguous nature of the role makes these nurses' daily experiences with decision-making a challenge. Using a phenomenological method, the lived experience of decision-making among telephone advice/triage nurses was explored by conducting multiple interviews with ten nurses. The internal structure of the lived experience was identified through the philosophical perspective …

Major Trauma Outcomes: At What Cost? And For Whom? A Cost-Effectiveness Analysis, A. Elaine Bond Dnsc, Msn, Aprn, Ccrn

Dissertations

The purpose of this triangulated descriptive study was threefold: (a) to identify the financial costs for acute trauma care, including costs for those who die early in treatment, and who pays those costs; (b) to identify the relationship between costs and severity of injury; and (c) to identify survivor functional and psychosocial costs, or quality of life, not only by current health care outcome criteria, but also from patients' and families' perspectives. Retrospective review determined the financial differences (total charges of $9,945,973 and institutional costs of $7,089,962) for 370 patients' severity of injury and functional outcomes at discharge, using the …

Reflections Of Reflections Of Reflections: A Multi-Case Study Of Women Educators' Callings To The High Arctic, Judith Knapp Edd

Dissertations

This study examines the stories of six women educators who were called to teach in remote Aboriginal communities in the Northwest Territories, Canada, from 1970 to 1985. Placed within a historical context, I set out to understand what called each educator to teach in a cultural context so different from her own in Canada's Arctic. In order to arrive at a deeper, more intrinsic understanding of her career decisions, I explored each educators calling through three, increasingly deeper levels of reflection. In Reflections, as “in an instance of reflecting,” I explored each participant's call to teach, specifically her calling to …
