The Relationship Of Teacher Attitudes Toward Evaluation And School Building Climate, Timothy James Lowe

Dissertations

Present management theory divides teacher evaluation into two categories, summative evaluation and formative evaluation. Summative evaluation is used for administrative decision making. Formative evaluation is used for shaping the performance of teachers. Traditionally, the evaluation process has been more summative than formative. Therefore, teachers have regarded evaluation with some apprehension.

In the 1960s, Halpin and Croft suggested that the climate of a school is analogous to its personality. School climate can be defined as the perception incumbents have of the organization. Degrees of climate can be organized along a continuum ranging from closed to open. A closed climate is characterized …

Development And Testing Of An Explanatory Model Of Registered Nurse Empowerment, Marilyn D. Klakovich Dnsc, Msn, Rn, Cnaa

Dissertations

Recent innovations in patient care delivery and nursing governance require an empowered workforce. However, little is known about what combination of organizational, leadership, and personal characteristics maximize the prediction of registered nurse empowerment. The purpose of this study was to develop and test an explanatory model of registered nurse empowerment. The predictor variables included personal characteristics of registered nurses (age, experience, organizational tenure, education, and position level of clinical and/or management responsibility), perceptions of organizational culture, and connective leadership. The study was conducted in a tertiary-care hospital in Southern California. A total of 113 registered nurses completed the Organizational Culture …

Sisters In The Hood, Deborah Burris-Kitchen

Dissertations

This research assembles and organizes the literature in the areas of African-American women, the political economy of racism, the Black feminization of poverty, drug use and distribution, and gang violence. This dissertation explores extant theoretical approaches with a special emphasis on their relationship to the underground economy. The researcher uses ethnographic methods to examine the role that female gang members play in the underclass drug infested community of south central Fort Wayne, Indiana. Of the Black females interviewed, some were drug dealers, others were using illegal drugs, and still others were females who just found themselves in the inner-city, in …

The Role Of Elites In The Quality Of Life In Kalamazoo And Calhoun Counties, Sam S. King

Dissertations

My research examined the role of elites in the quality of life from 1890 to 1990 in two southwestern Michigan communities: Kalamazoo and Calhoun counties. This research is grounded in three research literatures: community power, elites and quality of life. My approach combined a quantitative analysis of six dimensions of quality of life and an historical analysis using case methods to look at the two communities over a 100 year time span.

My assumption at the beginning of this study was that elites play a major role in the quality of life. My data showed that some elites did have …

The Impact Of Mentoring On Leadership Among Young African-American Females, Joyce A. Montgomery

Dissertations

The purpose of this study was to examine the perceived effectiveness of the mentoring relationship on the leadership behavior of female mentees in a community leaders program. More specifically, the researcher was concerned with what effects do the variables age, residence location, and family position have on aggressiveness, amount of influence, respect of knowledge, parental substitute and supportiveness components of leadership behavior among adolescent female mentees.

The target population consisted of 47 African-American adolescent females ages 14 through 18 years old attending the Community Leadership Program (CLP) based in Battle Creek, Michigan. The major data-gathering scale used, The Mentoring Leadership …

Lost In The Fifties: A Study Of Collected Memories, Janelle L. Wilson

Dissertations

This is a study of ordinary people's recollections of the decade of the nineteen fifties. The theoretical concepts of collective memory and collected memories guide design and analysis. Unstructured interviews with 33 individuals who grew up in America in that decade were conducted. The snowball method identified potential informants. The data from these interviews, combined with secondary sources on that time period, served to reconstruct this decade. A number of themes emerged from the data; the decade was seen: as an apolitical time, as fun and innocent, as fearful with respect to atomic weaponry and Communists, as problematic for race …

Public Choice Or Public Spirit: Toward A More Comprehensive Theory Of Regulation, Gary R. Kitts

Dissertations

This study examines the decisions made by state public utility regulatory commissions from the perspectives of two primary theories of regulatory decision making-- the public choice and public spirit models. The public choice model posits that an agency’s decisions are responsive to the pressures placed upon the organization by competing external interest groups. The public spirit model postulates that an agency’s decisions reflect the relative values of those with authority or influence within the organization. The study hypothesizes that each is incomplete and proposes a process model based on variables derived from both theories.

The research analyzed 240 utility rate …

Beliefs And Perceptions Of Michigan Superintendents Toward Females Advancing In The Ranks: Perspectives To Increase The Minority Pool, Dennis J. Stanek

Dissertations

The purpose of this study was to determine potential factors which affect the advancement of females in the role of superintendent. With the research pointing to a variety of causes for the low percentage of female superintendents, the reason for this study was to make various groups in leadership positions aware of such factors.

Three research questions were studied:

1. Do practicing K-12 male superintendents in Michigan possess significantly different beliefs and perceptions toward female superintendents than do practicing female superintendents?

2. What experiences did the respondent have in working with a female superintendent?

3. What perceptions do K-12 superintendents …

An Analysis Of Local Response To State Initiated School Reform Legislation: Michigan Public Act 25, A. Bruce Watson

Dissertations

Educational reform has been a topic of interest to educators, politicians and tax payers for over a century. Michigan’s educational reform legislation, Public Act 25. enacted in 1990, is a shared-responsibility model where the state and local school district share responsibility for implementing four major educational reform components. These components are, core curriculum, annual educational report, school improvement planning and accreditation.

The study was designed to answer the following two research questions. Initially, do elementary principals in Michigan public elementary schools perceive educational reform indicators and conditions to be in enough strength to allow educational reform to continue under Public …

Stress And Healthwellness, A Longitudinal Study, Howard Allen White

Dissertations

The purpose of this dissertation was to compare and examine the self-evaluated general health status of individuals in a five year longitudinal research study. Self-evaluations of health status have been shown to predict mortality, above and beyond the contribution to prediction made by indices based on the presence of health problems, physical disability, and biological or life-style risk factors.

The association between the stressful events of everyday living and the onset of the disease process suggests the importance of understanding the specific relationship under which stress is likely to result in illness. This research investigated the interrelationship of the different …

Community colleges are faced with the challenge of providing educational opportunities to an increasing and diverse population at a time of educational reform and decreasing financial resources. The colleges are expected to meet the changing needs of the communities they serve through open access, a diversity of high quality courses, and with schedules that accommodate the life styles of their students.

The study was designed to answer the following research question: Are there differences between the five leadership role groups, at Michigan’s 29 community colleges, regarding levels of awareness and understanding about distance education as a means of providing courses …

Experimental And Numerical Determination Of Fluid Velocity Profiles And Turbulence Intensity In Mixing Vessels, Chun-Chiao Chou

Dissertations

In this study, both a laser-Doppler velocimeter (LDV) and a computational fluid dynamic (CFD) software package (FL UENI) were used to experimentally determine and numerically predict the velocity distribution of an unbaffled and a baffled mixing vessel. Two types of impellers were employed, namely a flat blade turbine (FBT) and a pitched blade turbine (PBT). These impellers were studied in a single-impeller or multiple-impeller configuration in the unbaffled and baffled vessels. The flow characteristics in the impeller regions were measured by LDV and used as boundary conditions in the numerical computation. Turbulence effects were numerically simulated using either the k-c …

The purpose of this work is to introduce a set of Petri net-based tools and methods to address a variety of problems associated with the design and implementation of flexible manufacturing systems (FMSs). More specifically, this …

Theory, Design And Applications Of Linear Transforms For Information Transmission, Adil Benyassine

Dissertations

The aim of this dissertation is to study the common features of block transforms, subband filter banks, and wavelets, and demonstrate how discrete uncertainty can be applied to evaluate these different decomposition techniques. In particular, we derive an uncertainty bound for discrete-time functions. It is shown that this bound is the same as that for continuous-time functions, if the discrete-time functions have a certain degree of regularity.

This dissertation also deals with spectral modeling in filter banks. It is shown, both theoretically and experimentally, that subspectral modeling is superior to full spectrum modeling if performed before the rate change. The …

With the exception of a limited number of the most elementary radicals, accurate thermodynamic properties of alkyl radicals are either not available or only rough estimations exist. An H atom Bond Increment approach is developed and a data base [sic] is derived, for accurately estimating thermodynamic properties (ΔH_f°₂₉₈, S°₂₉₈ and Cp(T)) for generic classes of hydrocarbon radical species.

Reactions of alkyl radicals with molecular oxygen are one of the major reaction paths for these radicals in atmospheric photochemistry, oxidation of hydrocarbon …

Robust Approach To Object Recognition Through Fuzzy Clustering And Hough Transform Based Methods, Tianxiong Fu

Dissertations

Object detection from two dimensional intensity images as well as three dimensional range images is considered. The emphasis is on the robust detection of shapes such as cylinders, spheres, cones, and planar surfaces, typically found in mechanical and manufacturing engineering applications. Based on the analyses of different HT methods, a novel method, called the Fast Randomized Hough Transform (FRHT) is proposed. The key idea of FRHT is to divide the original image into multiple regions and apply random sampling method to map data points in the image space into the parameter space or feature space, then obtain the parameters of …

Design And Micro-Fabrication Of Tantalum Silicide Cantilever Beam Threshold Accelerometer, Chang Joo Kim

Dissertations

Microfabricated threshold accelerometers were successfully designed and fabricated following a careful analysis of the electrical, mechanical, and fabrication issues inherent to micron-sized accelerometers. A uniform cantilever beam was chosen because of the simplicity of design and fabrication. New models for the electrostatic force exerted on the cantilever beam were developed and calculations were made that accurately predicted the electrical characteristics of the accelerometer. The calculations also provided design guidelines for optimizing the accelerometer dimensions. Computer simulation demonstrated that the error of the electrostatic force, calculated using the most accurate model, was within 2% of the actual force which was obtained …

Electrical Characteristics Of Novel Heterojunction Diodes Of Thin Relaxation Semiconductors/P-Si/, Hyung Joo Lee

Dissertations

The relaxation semiconductor is defined as one in which the dielectric relaxation time (τd;resistivity times permittivity) is greater than lifetime (τo). Non-hydrogenated amorphous Silicon Carbide (SiC) and KrF excimer laser induced disordered Si were used for the relaxation semiconductors. Both semiconductors have high resistivity, wide energy gap, and numerous defects. A novel diode, consisting of those semiconductors on p-type crystalline Silicon (c-Si), was fabricated. In the diode structure, an injecting contact was made on the relaxation material and a Schottky barrier contact was made on the c-Si.

Electrical characteristics of both diodes were found to have interesting …

Analysis Of Plates And Reinforced Concrete Columns By Cubic B-Spline Function, Gang Wang

Dissertations

Applying spline functions to numerical structural analysis has been more common in recent years. The recent increase use of spline functions is mainly due to their excellent characteristics, such as sectionalized continuity, linear combination, flexibility, and easy use for various boundary conditions. The whole deformed shape of some structures or substructures can be described with one displacement function constructed by a series of spline functions. By doing this, the mesh generation and the huge computer memory space are no longer needed because only one single superelement can be used in the whole process. The choice of spline functions as displacement …

On Adaptive Code Division Multiple Access Detectors, Wenping Chen

Dissertations

Several variations of adaptive CDMA synchronous receiver schemes which can automatically adjust to the system parameters, are studied in this dissertation. Unlike their non-adaptive counterparts, these adaptive detectors require no knowledge of the received signals' energies and have similar or better performance.

Minimum energy and decorrelating criterion are used to update the weights. Since weights are updated according to the changes of the detector's outputs, hence no training sequence is required. The convergences of some of the aforementioned adaptive detectors are also disscussed.

The detectors proposed in this dissertation are near-far resistant,thus rendering the high-precision power control unnecessary. Among them, …
