Parallel Simulation Of Microflows By Dsmc And Burnett Equations, Yichuan Fang

Dissertations

The primary objective of this dissertation is to numerically simulate and study the heat transfer and flow characteristics in fluidic microelectromechanical system (MEMS). In typical microfluidic MEMS applications, the ratio of the gas mean-free-path to the characteristic length scale, or the Knudsen number, can be large. The traditional mathematical models of continuum fluid based on the Navier-Stokes equations may become invalid because of their constitutive relations of viscous stress and heat flux.

In this study, the direct simulation Monte Carlo (DSMC) method and the conventional Burnett equations are applied to model the microflows in microchannels from molecular and continuum point …

Group Processes In Group Supervision: A Quantitative And Qualitative Study, Jeremy M. Linton

Dissertations

Although group supervision is widely employed with counselors during their training (Holloway & Johnston, 1985; Prieto, 1998) little research concerning its practice has been offered in the literature. The fact that group supervision practices appear to be based on assumptions that lack empirically-based support has led some researchers to raise ethical concerns regarding its continued use (Hess, 1997; Prieto, 1996). In particular, many have raised concerns regarding counselor educators and supervisors' lack of understanding regarding the role of group processes in group supervision. Accordingly, this exploratory studysought to investigate counselor-trainees' experiences of group processes in group supervision. The study also …

Effects Of Writing Therapy Across Ptsd And Chronic Stress, Jennifer E. Lewis

Dissertations

Research supports the effectiveness of writing therapy in reducing physical health problems and increasing positive feelings (Pennebaker & Beall, 1986). More recently, research indicates that writing about traumatic experiences is as effective as EMDR in reducing symptoms of Post Traumatic Stress Disorder (Largo-Marsh & Spates, 1997). The current study assessed the treatment efficacy of writing therapy for individuals with varying degrees of stress related symptoms. Specifically, this study examined writing treatment for Post-Traumatic Stress Disorder and work-related chronic stress or "burnout."

The study utilized a pretest-posttest comparison group design. Repeated measurements !)n primary dependent variables were collected at pretest through …

Interspecies Encounters: An Ethnography Of A Veterinary Hospital, Dana Atwood-Harvey

Dissertations

There were three broad reasons for this research. The larger goal was to continue to advance the incorporation of 'other' animals and the rest of nature in general in sociological theory and research. The second was to suggest to those who have incorporated 'other' animals into their research, to include them as participants. The third was to redirect the focus of those who have incorporated 'other' animals as participants, to the impact that ideological structures and other social factors have on human-'other' animal encounters. Toward this end, I directed the focus of my study to examine human-'other' animal encounters ina …

Organizational Power And Politics: More Than Meets The Eye In Program Planning, Susan Shaver

Dissertations

Organizational power and politics influence corporate training in ways not often discussed. This study explores the effects of organizational power and politics on program planning and how planning, with its inherent power and politics (see Cervero & Wilson, 1994a), influences the daily practices of corporate trainers.

This study was informed by the literature of systems theory and constructivism. Von Bertalanffy’s (1968) general systems theory, in which the whole of a system is considered to be greater than the sum of its parts, Senge’s (1990) systems view that interrelationships within organizational structures, (not events), underlie complex situations, and Lincoln & Guba’s …

Essential Elements Of An Implementation Process For Grant-Funded Projects/Programs In Nonprofit Organizations, Margaret M. Bernhard

Image Enhancement Techniques Applied To Solar Feature Detection, Artur J. Kowalski

Dissertations

This dissertation presents the development of automatic image enhancement techniques for solar feature detection. The new method allows for detection and tracking of the evolution of filaments in solar images. Series of H-alpha full-disk images are taken in regular time intervals to observe the changes of the solar disk features. In each picture, the solar chromosphere filaments are identified for further evolution examination. The initial preprocessing step involves local thresholding to convert grayscale images into black-and-white pictures with chromosphere granularity enhanced. An alternative preprocessing method, based on image normalization and global thresholding is presented. The next step employs morphological closing …

New Full Wave Theory For Plane Wave Scattering By A Rough Dielectric Surface - The Fictitious Current Method, Byung-Tae Yoon

Dissertations

A new full wave method for scattering of plane waves from a rough dielectric surface is developed. This new theory begins by postulating a zero-order field solution which does not satisfy Maxwell's source-free field equations. The zero-order field, however, is made to satisfy Maxwell's source equations. This is done by introducing a fictitious volume current distribution. Since the original problem does not possess a volume current distribution, its introduction represents a measure of the error in the postulated zero-order solution. To improve this solution, the fictitious volume current distribution is cancelled by the introduction of a second fictitious current distribution, …

Dynamic Multi-Ramp Metering Control With Simultaneous Perturbation Stochastic Approximation (Spsa), Jiangtao Luo

Dissertations

Ramp metering was proven to be a viable form of freeway traffic control strategy, which could eliminate, or at least reduce, freeway congestion. In this study, the development of ramp metering control strategies, models, and constraints (e.g., meter locations, ramp storage capacities, lower and upper bounds of ramp metering rates) are discussed in detail. The pre-timed and demand/capacity metering control strategies were first evaluated, while the potential metered ramps were determined. A Simultaneous Perturbation Stochastic Approximation (SPSA) algorithm is proposed to dynamically optimize multiple-ramp metering control by maximizing the total throughput subject to a number of constraints. The ramp metering …

Goddesses In The Union: A Qualitative Study Of Women In Leadership Positions In College And University Union Settings, Susan H. Payment Edd

Dissertations

The field of university union management attracts individuals that enjoy working in complex, high-energy environments where learning and student development are encouraged. Despite the overwhelming presence of women in today's workforce, the realm of university union management remains dominated by men. A “glass ceiling” appears to exist in this …

The Relationship Between Decision-Making And Accountability: A Case Study Of Two State Community College Systems, Bonnie Ann Dowd Edd, Mba, Bba

Dissertations

Inherent to college governance in many community colleges throughout the nation is the expectation that a collegial or participatory model of decision-making is the appropriate mode of governance. This type of model structures an organization to allow the opportunity for all constituencies to participate in decision-making. Some states, such as California, have mandated a participatory decision-making process, commonly referred to as “shared governance” (AB1725) while others operate in a similar manner but not by legislative mandate. Regardless of the model of decision-making used to govern community colleges, most states are being asked to address educational accountability with regard to student …

Influential Factors Contributing To Exercise Compliance Following A Structured Lifestyle Change Program, Wayne E. Borin Edd

Dissertations

Cardiovascular disease remains the number one cause of death in the United States, with five hundred thousand people diagnosed annually. Even though regular exercise has been shown to dramatically reduce the risk of cardiovascular disease, few hospitals offer programs that focus on the requisite lifestyle changes for participants to maintain long-term exercise programs. In an effort to determine what factors contribute to long-term exercise compliance, this study surveyed 279 participants of the Scripps Ornish/Healing Hearts program, a comprehensive lifestyle change program, to identify the factors that helped explain variation in exercise compliance among program completers. Results of the hierarchical multiple …

The Use Of Quality Indices For Successful Programs For Students With Emotional/Behavior Disorders In The State Of Michigan, Alice Brouwer Hoekstra

Dissertations

Recent research studies have determined that students with emotional and behavior disorders (EBD) are the most difficult to integrate into the general education environment. Students with EBD are most likely to be educated in separate settings and least likely to be found in traditional education environments. However, the mandate of the Individuals with Disabilities Education Act reauthorized in 1997 (IDEA '97) and the Least Restrictive Environment (LRE) regulation indicates all educators, including administrators, have the responsibility to challenge teachers and schools to be more inclusive regarding students with EBD and to provide services that better support students in this setting. …

Development And Psychometric Evaluation Of The Wikoff Spiritual Focus Questionnaire, Karen Luther Wikoff Phd

Dissertations

Spirituality is a concept that has been a part of nursing since nursing began. In every culture spirituality is a component of healing. However, in the United States, nurses seldom assess the concept of spirituality and the patient's spiritual needs are often not addressed. Wikoff Spiritual Focus Questionnaire was designed to help nurses assess and meet the patient's spiritual needs. A review of literature revealed that spirituality was comprised of a relationship between a Higher Power, Self, Others, and Nature which resulted in a sense of being, knowing and life purpose. A fifth dimension of Religion was identified through a …

An Experimental Analysis Of The Effects Of Reading Interventions In A Small Group Reading Instruction Context, Christine M. Bonfiglio

Dissertations

An Analysis Of The Level Of Union Membership In The United States Since The Implementation Of Nafta, David D. Westcot

Dissertations

Union membership in the United States has been in a state of decline over the last two decades and international trade has been cited as one of the reasons. As such, U.S. labor unions perceived the 1994 implementation of the North American Free Trade Agreement (NAFTA) as an assault on organized labor. This perspective is based on the belief U.S. capital and jobs would move jobs south in an effort to take advantage of Mexico's low-wage differentials. With this in mind, the objective of this research was to determine if the percentage of union membership in any of the 22 …

The Extent To Which Teachers And Principals Perceive High Schools As Learning Organizations, Scott Kemple

Dissertations

The purpose of the study was to conduct an assessment of the culture and leadership of a sample of Michigan high schools as perceived by their teaching staff and principals.

The variables of culture and leadership are primary indicators of whether a school is viewed as a learning organization by the faculty, staff and administration of the school (Leithwood et al., 2001). Five primary questions were examined: (1) To what extent are high schools perceived as learning organizations by their principals? (2) To what extent are high schools perceived as learning organizations by their teachers? (3) Is there a difference …

Identifying The Function Of Aberrant Behavior: Comparing Variations Of The Experimental Functional Analysis, Kathryn M. Potoczak

Dissertations

The advent of the experimental functional analysis has had a significant effect on the field of behavior analysis in shifting the focus from topography-based interventions for aberrant behavior to treatment based on function. The original method developed by Iwata, Dorsey, Slifer, Bauman, and Richman in 1982 utilized attention, demand, alone, and play conditions in a multielement design. Its effectiveness in determining the function of aberrant behavior using both antecedents and corresponding contingencies of reinforcement is well established, and it is the most prevalent method of functional assessment used today.

However, an alternative to the Iwata et al. (1982) procedure exists. …

Role That Professional Positioning And Professional Socialization Play In The Career Path Of African American Women Superintendents, Cheryl Celestin

Dissertations

This dissertation examines the professional positioning and professional socialization of African American women school superintendents in the Mid-West area of the United States. Numerous studies revealed that there are very few African American women superintendents (Glass, 2000; Alston, 2000; Brunner, 1999; Ortiz, 1998; and Jackson, 1995). Women educators in general and African American women educators more specifically were not placed in professional paths that normally lead to the superintendency (Alston, 2000; Gardiner, Enomoto and Grogan, 2000; and Shakeshaft, 1987). The ladder to the school superintendency had historically included male dominated line positions such as athletic coaching and band directing with …
