The purpose of this ethnographic research was to discover the influence of President Judith Valles' gender and ethnicity on her leadership behavior at Golden West College in Huntington Beach, California, and to determine if similar influences existed among the other eight Hispanic women presidents of community colleges in the U.S. A composite profile of the nine presidents was developed. More than 100 interviews were conducted from a broad spectrum of participants, including seven of the nine Hispanic women presidents. The researcher became a participant observer at Golden West College for the fall of 1991. All the presidents were strongly influenced …

Valuing A Culturally Diverse Work Force: An Examination Of Intended Changes And Successes As Perceived By Upper And Middle Management, Supervisors, And Line Staff In A Health Care Organization, Cynthia L. Camberg Edd

Dissertations

The growing diversity of the work force is having and will continue to have a significant impact on organizations. The diversity of cultures, lifestyles, and household compositions compels managers and organizational leaders to make a variety of organizational changes. Additionally, the globalization of business, the integration of the world economy, and the rapid changes in corporate life require a reexamination of how organizations are thought of, and how employees are managed (Copeland, 1988; Betters-Reed & Moore, 1988-89; Goldstein, 1988). Since in the past organizations have been based on white male European traditions, a revolutionary response is needed from organizational leaders …

Behavior Of Square And L-Shaped Slender Reinforced Concrete Columns Under Combined Biaxial Bending And Axial Compression, Wen Hu Tsao

Dissertations

A numerical analysis was developed to evaluate the complete load-deflection and moment-curvature relationships for square and L-shaped slender reinforced concrete columns subjected to biaxial bending and axial load. This computer model can be used for any cross section geometry and material properties of normal concrete. The analysis was based on a deformation control and both the ascending and descending branches of curves can be studied. The finite difference method was introduced to calculate the deflections which satisfy the compatibility equations. Six square slender columns and eight L-shaped slender columns were tested to compare their experimental load-deformation results with the analytical …

A Generalized, Parametric Pr-Qmf/Wavelet Transform Design Approach For Multiresolution Signal Decomposition, Hakan Caglar

Dissertations

This dissertation aims to emphasize the interrelations and the linkages of the theories of discrete-time filter banks and wavelet transforms. It is shown that the Binomial-QMF banks are identical to the interscale coefficients or filters of the compactly supported orthonormal wavelet transform bases proposed by Daubechies.

A generalized, parametric, smooth 2-band PR-QMF design approach based on Bernstein polynomial approximation is developed. It is found that the most regular compact support orthonormal wavelet filters, coiflet filters are only the special cases of the proposed filter bank design technique.

A new objective performance measure called Non-aliasing Energy Ratio(NER) is developed. Its merits …

Organizational Development Through The Implementation Of Strategic Plans, Susan M. Eickhoff

Dissertations

Organizations today need effective and efficient total organizational change strategies in order to ensure both short- and long-term organizational health. As a result of an organization being a multi-dimensional entity, the ingredients for its change strategy must necessarily be representative of all its dimensions such as business management, information system, behavior analysis, behavioral systems analysis, total quality management and statistical process control techniques. Those ingredients of a comprehensive change strategy exist but have not been put together into a totally integrated package so far. In the present study, a fully-integrated organizational change strategy was systematically employed with the goal of …

Administrative And Faculty Development: A Study Of Academic Chairpersons, Mary Ann Bowman

Dissertations

The professional development of academic chairpersons has been neglected both by higher education institutions and as a field of study. This study focused on assessing both the perceptions of chairpersons toward administrative and faculty development and their degree of participation in development activities and roles.

A survey instrument was designed to make this assessment and was mailed to 311 chairpersons at eight midwestern public universities classified as Doctorate-Granting Universities I. The response rate was 75%, with 234 questionnaires returned .

The results of the survey showed that although chairpersons view both administrative development and faculty development as important, faculty development …

Integrated Anaerobic-Aerobic System For The Biodegradation Of Highly Chlorinated Aromatic Compounds, Cheng-Ming Kung

Dissertations

A two-step process was developed for the complete mineralization of hazardous chlorinated aromatic compounds. The system consisted of an anaerobic reactor, in which reductive dehalogenation took place, coupled with an aerobic reactor in which the complete mineralization of the products of the anaerobic dehalogenation occurred.

A mixed anaerobic culture from a municipal sewage treatment plant was enriched and then immobilized on silica-based porous beads to treat 2,4,6-trichlorophenol (TCP), which is the model target compound in this work. In the anaerobic reactor, TCP was degraded to 2,4-dichlorophenol which was, in turn, reduced to 4-chlorophenol (4-CP). Stoichiometric amounts of 4-CP were recovered …

Crystallization Kinetics And Polyblends Of Poly(Ethylene Terephthalate) Recycled From Post-Consumer Beverage Bottles, Peming Peter Hsu

Dissertations

In order to reduce waste generation, and comply with state and federal laws, plastic beverage bottles are usually undergoing recycling. Poly(ethylene terephthalate) [PET], which is the main component the bottles are made of, cannot be used for manufacturing new food containers, and has to be used for manufacturing other end consumer products. The recycled PET is a cheap material, but its use is problematic due to the low crystallization rates of PET. The present study investigates ways of accelerating PET crystallization by using inorganic carbonate salts as nucleating agents. This study also explores the possibility of forming polymer blends based …

Effects Of Interactive And Linear Video On Patient Understanding Of Risks In Medical Procedures, Christopher P. Giuliano

Dissertations

Three methods of providing information relevant to informed consent where a vaginal birth after cesarean section was being considered were evaluated; (1) the traditional and common method (physician presentation), (2) Linear Video Tape (LVT), and (3) Interactive Video Disc (IVD). The traditional and common method of presenting information led to only limited acquisition of knowledge resulting in patients making less than fully-informed decisions. Both the linear video tape and the interactive video disc led to significantly greater understanding of the risks and benefits of the procedure than did the physician presentation. The interactive disc and the linear video tape were …

A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak

Dissertations

The growth of specialized schools that emphasize science and mathematics has raised questions about their efficacy in improving performance in various parameters in mathematics and science. In this study, four different components were compared. A science and mathematics experiences questionnaire determined the type and extent of student experiences in science and mathematics during high school, and student interest in science and mathematics careers. The American College Testing Program (ACT) (ACT Registration) sub-scores assessed scholastic achievement, while the determination of student attitudes towards science used the Scientific Attitude Inventory (SAI) (Moore & Sutman, 1970).

Subjects in the study consisted of three …

Contrived Versus Natural Reinforcers In The Acquisition Of A Verbal Repertoire By Adult Learners, Lisa Ann Leblanc

Dissertations

Previous research suggests that by making classroom contingencies for verbal responding more like those in the natural environment, i.e., by using motivative variables to evoke verbal responses which are followed by specific actions on the part of listeners, verbal repertoires can be taught more effectively to children and language impaired individuals. The present study examines the role of specific versus generalized conditioned reinforcement following adult students' question-asking on the acquisition of a verbal repertoire in a classroom setting and on the generalization of this repertoire to a more natural verbal environment.

Subjects were 32 university students in two American Sign …

Mathematical Modeling Of Mass Transfer In Microvascular Wall And Interstitial Space, Daekyung Kim

Dissertations

The dynamics of macromolecular transport across the microvascular wall and into the adjoining interstitial space was studied in the hamster cheek pouch using intravital fluorescence microscopy in combination with digital image processing. Fluorescein isothiocyanate-labe led dextrans (FITC-Dx) of 70,000 and 150,000 daltons were used as tracers. In each experiment, the time-dependent extravasation of FITC-Dx from a leakage site in a blood vessel was videotaped for about 2 hours. The macromolecular transport from individual microvessels was quantified by digital video-image processing. Histograms of the light intensity distributions for selected fields at various times were obtained and then converted to the interstitial …

The Theory Of Bootstrapped Algorithms And Their Applications To Cross Polarization Interference Cancelation, Abdulkadir Dinc

Dissertations

Dual-polarized transmission has become an important method for frequency re-use, particularly in satellite and microwave radio communication. Nevertheless, cross-polarization interference, which is inherent to this method, may cause degradation in system performance.

Different canceler [sic] structures have been proposed to mitigate the effect of cross-polarization. Among these are the diagonalizer, the least mean square (LMS) canceler [sic] and the bootstrapped cancelers [sic]. Bootstrapped canceler [sic] schemes have been proposed and implemented in different applications, such as satellites, tactical communications, and quadrature amplitude madulation [sic] (QAM) dual polarized microwave radio. Nevertheless, no attempt was made in the past to quantify the …

Mathematical Modeling Of Chemical Vapor Deposition Processes And Its Application To Thin Film Technology, Norman W. Loney

Dissertations

A number of workers in the field of Chemical vapor deposition (CVD) have presented mathematical models in the literature. Some workers were able to produce analytical expressions for the interwafer concentration profile. These analytical expressions were based entirely on zero or first order chemical reaction rates. Until now, it appears that a chemical reaction rate expression that is not zero or first order directly, must be handled by a numerical scheme.

Presented herein is a mathematical model with an analytical interwafer concentration profile. This concentration profile is neither zero nor first order but shifts from zero to first order as …

Investigation Of Stagnation Flow Heat Transfer For A Heated Horizontal Round Plate, Ching-Hua Wei

Dissertations

The heat transfer characteristics in stagnation flow are investigated through three cases in this study. The first is forced convection by an array of air jets; the second is free convection of a downward-facing heated round plate; the third is free convection of an upward-facing heated round plate.

The first case is investigated by systematic experiments which examine the heat transfer characteristics mainly by five air jets impinging normally to a flat plate, with varying nozzle diameters, and Reynolds numbers, at different distances between the nozzles and the plate. The empirical formulas of heat transfer around the stagnation point and …

Kinetic Studies On Pyrolytic And Oxidative Decomposition Of Chlorocarbons In A Tubular Flow Reactor, Yang Soo Won

Dissertations

Chloroform decay and product distributions were distinctly different in the absence and presence of added O₂ and/or CH₄. Increases in O₂ concentration were observed to speed reagent loss, with a slower decay of chloroform observed for the CHCl₃/CH4/Ar pyrolysis system. In CHCl₃/CH₄/O₂, the major products were C₂Cl4, CH2CCl₂, C₂HCl₃, CO and CO₂ over a wide temperature range. Minor products included CH₂Cl₂, CH₃Cl, and C2H₃Cl. When CH₄ reactant was not present, …

A Study Of Leadership: A Qualitative Case Study Of Intended Changes Within The County Government Of San Diego, Shelia Quinlan Williams Edd

Dissertations

This research addresses the nature of leadership. Reflecting a sound theoretical base, the researcher studied the people involved in a complex change process, and listened to their perceptions about change and leadership. The study goes beyond the idea of the individual leader into the notion of a leadership relationship. It is a study of the persons who were active in the relationship, a study of their behaviors and language as they changed how the county government served the public. One of the primary purposes of the study is to demonstrate how these insights regarding change and the nature of leadership …

Choice By Rats For Enriched Versus Standard Home Cages Plastic Pipes, Wood Platforms, Wood Chips, And Paper Towels As Enrichment Items, Anita Lynn Bradshaw

Dissertations

The purpose of the present study was to determine whether simple additions to the home cages of rats made those cages preferable to standard housing arrangements. Results indicated that the majority of rats preferred cages with wood platforms, wood chips, and paper towels to otherwise identical cages without these items. Wood chips were not, however, practical with the cages used in the present study. Plastic pipes caused no problems but were not preferred by the majority of individual animals. Both wood platforms and paper towels created no problems and appeared to be useful as enrichment items. The latter were preferred …
