Introduction of Self-Manage Work Teams at a Brownfield Site: a Study of Organization-Based Self-Esteem and Performance

Description: This empirical study is aimed at understanding the patterns of relationships among the organization structure of self-managed work teams in terms of three sets of constructs: 1. organization-based self-esteem; 2. consequent behaviors of intrinsic work motivation, general job satisfaction, organization citizenship, and organization commitment; and 3. performance. The primary significance of this study is that it adds to the pool of empirical knowledge in the field of self-managed work team research. The significance of this study to practicing managers is that it can help them make better-informed decisions on the use of the self-managed work team structure. This study was a sample survey composed of five standardized questionnaires using a five-point Likert-type scale, open-ended questions, and demographic questions. Unstructured interviews supplemented the structured survey and for means of triangulation of results. The variables were analyzed using regression analysis for the purpose of path analysis. The site was a manufacturing plant structured around self-managed work teams. The population was full-time, first-line production employees.

South-East Asia College: History, Development, Problems, and Issues Related to Achieving University Status

Description: The purpose of this study is to describe the history, development, problems, and issues related to achieving university status of South-East Asia College from 1974 to 1993. This historical research used records and documents from South-East Asia College and the Association of Private Higher Education Institutions of Thailand as primary sources. Also interviews with the president, faculty and staff of South-East Asia College were used. Secondary Sources were reports and publications from the Ministry of University Affairs in Thailand. The areas of emphasis in the study were government policies on private higher education, legislation that initiated the founding of the college, the founder, the college's goals, financial sources, curriculum, library, faculty, students, and buildings. It was found that the Thai government encourages the establishment of private higher education institutions. The Private Higher Educational Institution Act of 1979 was enacted to allow private universities to be equal to government universities. South-East Asia College was founded in 1974 by the Khunya Plak Muanpiew Foundation with the purpose of training Thai students for industrial technologies and business sectors. The college requested university status in April, 1987. The first attempt was turned down. Four areas not meeting the requirements were the library, faculty, students, and buildings. The college made a second request in December, 1991, and the change in status of South-East Asia College to South-East Asia University was approved in March, 1992. Suggestion for further study include: (a) the study is limited to one private university; a further investigation should be made of the other private institutions; and (b) a study should be conducted to identify factors which will contribute to the future development of South-East Asia University.

Multiresolution Signal Cross-correlation

Description: Signal Correlation is a digital signal processing technique which has a wide variety of applications, ranging from geophysical exploration to acoustic signal enhancements, or beamforming. This dissertation will consider this technique in an underwater acoustics perspective, but the algorithms illustrated here can be readily applied to other areas. Although beamforming techniques have been studied for the past fifty years, modern beamforming systems still have difficulty in operating in noisy environments, especially in shallow water.

The Monstrance: A Collection of Poems

Description: These poems deconstruct Mary Shelley's monster from a spiritually Chthonian, critically post-structuralist creative stance. But the process here is not simple disruption of the original discourse; this poetry cycle transforms the monster's traditional body, using what pieces are left from reception/vivisection to reconstruct, through gradual accretion, new authority for each new form, each new appendage.

The History of the Bill J. Priest Institute for Economic Development of the Dallas County Community College District

Description: The Bill J. Priest Institute for Economic Development is an entity created in the Dallas County Community College District to serve the community in workforce and economic development. The history of the Priest Institute over the last ten years parallels and illustrates the commitment of community colleges nationally to workforce and economic development. The history also reflects similar goals and trends within the state of Texas and, particularly, in the city of Dallas. The Priest Institute is made up of three distinct entities. One entity is the Edmund J. Kahn Job Training Center; another is the Business and Professional Institute, which provides consulting and training services to business clients. The final service area is the complex made up of the regional North Texas Small Business Development Center and its several related local service operations. This study provides an analytical history of each of these components and the process by which they came together in a model facility in Dallas. This study also describes perceptions of persons within the Institute regarding its present mission and purposes and the efficacy of the current organizational structure both internally and within the district operation as an appropriate structure enabling the Institute to meet its goals.

Transport Processes in Synchrotrons

Description: This thesis examines the evolution of beams in synchrotrons. Following an introduction to accelerator physics in Chapter 1, in Chapter 2 I describe the Fermilab E778 'diffusion' experiment. Families of sextupoles were powered to drive the 2/5 resonance, and a beam was then kicked to populate a nonlinear region of the transverse phase space. The beam was then observed over periods of approximately 30 minutes for a variety of kick amplitudes and physical apertures. In Chapter 3 comments about the analytic treatment of such systems are discussed, including the assumptions inherent in the conventional treatment. I motivate my use of a simplified model in Chapter 4 after examining common computational methods. Deriving the model from the formalism of traditional accelerator physics, I discuss its implementation on a massively parallel computer, the Intel iPSC/860 hypercube, and examine the performance of this algorithm in detail. Using the simple model to perform the numerical experiment equivalent to E778 is the subject of Chapter 5. I derive the parameters needed for the simple model based upon the physical experiment. Both three dimensional cases and cases with reduced dimensionality are run. From power supply ripple data and an electrical model of the magnet string, I compute tune modulation depths, and a subset of these are run. I conclude that tune modulation from power supply ripple is not a significant source of transport for this system. In Chapter 6, the intensities of the beams are used to compare the experimental and numerical runs, using both exponential and algebraic decays, and the algebraic form is seen to provide a better fit. The agreement between numerical and experimental results is best for fully three-dimensional runs, but the numerical results show slower decay than the experimental. Individual particles are examined, whose motion consists of stochastic motion interspersed with regular ...

The Preparedness for Emergency Conditions of Public Schools in Texas

Description: A survey of Texas public schools was conducted to determine the state of their emergency preparedness programs with particular interest in hazard analysis, disaster experience, chain of command of responsibility, personnel training, and inter-agency cooperation. A model emergency management plan was proposed. A stratified random sample of all Texas public school districts was drawn from the twenty education service center regions and university interscholastic league district size classifications. Of the 275 districts sampled, 214 questionnaires were completed for a 78% return. The strong return justified a generalization to the entire population.

Responses of Selected Texas Fishes to Abiotic Factors, and an Evaluation of the Mechanisms Controlling Thermal Tolerance of the Sheepshead Minnow

Description: Low oxygen tolerances of ten fishes were estimated using an original nitrogen cascade design, and reciprocally transformed to express responses as ventilated volume necessary to satisfy minimal oxygen demand (L·mg O2^-1). Values ranged from 0.52 to 5.64 L·mg^-1 and were partitioned into three statistically distinct groups. Eight stream fishes showed moderately high tolerances reflecting metabolic adaptations associated with stream intermittency. Juvenile longear sunfish and two mollies comprised the second group. High tolerance of hypoxia may allow juvenile sunfish to avoid predation, and mollies to survive harsh environmental oxygen regimens. The sheepshead minnow was the most tolerant species of low oxygen, of those examined, explaining its presence in severely hypoxic environments.

Practical Aspects of Playing Domenico Scarlatti's Keyboard Sonatas on the Guitar, a Lecture Recital, together with Three Recitals of Selected Works by W.A. Mozart, M. Ponce, A. Vivaldi, J.S. Bach, J. Turina and Others

Description: The ornamentation in the keyboard sonatas by Domenico Scarlatti is investigated in light of evidence from late seventeenth and early eighteenth century Spanish treatises and collections. Additionally, calligraphic and statistical evidence from the earliest known manuscripts and printed source for the keyboard sonatas is explored. The study is focused on three ornaments--the appoggiatura, trill, and tremulo--and concludes that: the appoggiaturas in this repertoire were short unless cadential or present in a cantabile tempo, in which case they could be one-third to two-thirds the value of the resolution note; trills were begun on the main note unless preceded by a grace note; tremulo was usually an alternation of a main note with its lower neighbor note and this ornament is normally indicated at points of harmonic prolongation. The last chapter discusses general approaches to arranging these works for the guitar and the specific influence of ornamentation on the performance of the sonatas on guitar. Details from eight sonatas arranged for the guitar are used to exemplify the conclusions of the research.

Recognition of Face Images

Description: The focus of this dissertation is a methodology that enables computer systems to classify different up-front images of human faces as belonging to one of the individuals to which the system has been exposed previously. The images can present variance in size, location of the face, orientation, facial expressions, and overall illumination. The approach to the problem taken in this dissertation can be classified as analytic as the shapes of individual features of human faces are examined separately, as opposed to holistic approaches to face recognition. The outline of the features is used to construct signature functions. These functions are then magnitude-, period-, and phase-normalized to form a translation-, size-, and rotation-invariant representation of the features. Vectors of a limited number of the Fourier decomposition coefficients of these functions are taken to form the feature vectors representing the features in the corresponding vector space. With this approach no computation is necessary to enforce the translational, size, and rotational invariance at the stage of recognition thus reducing the problem of recognition to the k-dimensional clustering problem. A recognizer is specified that can reliably classify the vectors of the feature space into object classes. The recognizer made use of the following principle: a trial vector is classified into a class with the greatest number of closest vectors (in the sense of the Euclidean distance) among all vectors representing the same feature in the database of known individuals. A system based on this methodology is implemented and tried on a set of 50 pictures of 10 individuals (5 pictures per individual). The recognition rate is comparable to that of most recent results in the area of face recognition. The methodology presented in this dissertation is also applicable to any problem of pattern recognition where patterns can be represented as a collection of black ...

Orchestral Accompaniment in the Vocal Works of Hector Berlioz

Description: Recent Berlioz studies tend to stress the significance of the French tradition for a balanced understanding of Berlioz's music. Such is necessary because the customary emphasis on purely musical structure inclines to stress the influence of German masters to the neglect of vocal and therefore rhetorical character of this tradition. The present study, through a fresh examination of Berlioz's vocal-orchestral scores, sets forth the various orchestrational patterns and the rationales that lay behind them.

Adult Christian Education for Baby Boomers: a Descriptive Case Study of Three American Churches

Description: American churches seeking to assimilate baby boomers are struggling to meet the adult educational needs of this group. To determine what models of church-based adult education are used to meet the educational needs of this group, three large, growing American churches known for attracting boomers were identified as sites for research. A qualitative case study research design was used and results were compared using cross-case analysis. Initial data collection included a three-day visit at each church. Data were collected in three phases: Phase One consisted of personal interviews with staff and lay leaders; Phase Two focused on observation of adult education events which took place during the visitation period; Phase Three involved gathering materials that described adult education programs. To optimize the reliability and accuracy of the findings data were subjected to examination by peers, collection methods were applied consistently in each research phase, follow-up contacts were made with each church to verify observations and findings, and case records were created for each site. Eleven categories were selected and the data were presented by category. Within each category, data were delineated and organized into three areas: trends among the churches, noteworthy comments about individual programs, and comparison to the literature in the adult education field.

An Analysis of Preferred Equity Redemption Cumulative Stock

Description: This dissertation examines whether Percs, Preferred Equity Redemption Cumulative Stocks, are properly priced regarding to the relevant securities, such as the underlying common stock, the long-term call option of the stock, and so on. Test results indicate that Percs were overpriced with respect to the equivalent packages composed of the relevant securities. Further tests on arbitrage restrictions show that transaction costs would prevent arbitrage profits. This dissertation also examines the market reactions to Percs offerings. Test results reveal that the market reactions to the announcement of Percs offering and the actual issuance are both significantly negative. Compared to the market reaction on common stock offering announcement, the market reaction on Percs offering announcement is weaker. The overpricing of Percs and the weaker reaction of the market suggest that Percs may have advantages in transaction costs, taxes and some corporate finance issues.

Early Childhood Educators' Beliefs and Practices about Assessment

Description: Standardized tests are being administered to young children in greater numbers in recent years than ever before. Many more important educational decisions about children are being based on the results of these tests. This practice continues to escalate despite early childhood professional organizations' calls for a ban of standardized testing for children eight years of age and younger. Many early childhood educators have become dissatisfied with multiple-choice testing as a measure of student learning and are increasingly using various forms of alternative assessment to replace the more traditional testing formats. Teachers seem to be caught in the middle of the controversy between standardized testing and alternative assessment. This research examined what early childhood educators in one north Texas school district believe about assessment of young children and what assessment methods they report using in their classrooms, as well as factors which influence those beliefs and practices. The sample for this study was 84 teachers who taught prekindergarten through third grade. An eight-page questionnaire provided quantitative data and interviews and the researcher's journal provided qualitative data.

The Historical Development of the University of Texas of the Permian Basin, Odessa, Texas

Description: The University of Texas of the Permian Basin (UTPB) is a public university that serves over 4,500 undergraduate and graduate students as a branch of the University of Texas system located in Odessa, Ector County, Texas. The UTPB was established as an upper-division and graduate school on February 4, 1969, and first opened its doors to students in September, 1973. This historical study focuses on the development and progress of the UTPB from its inception until it was elevated from an upper-level institution to a four-year university twenty-two years later. The formation, mission, and curriculum are examined as well as are faculty and student characteristics and support. This study addresses the background history of higher education in the region, the role of community and college leaders in the UTPB's creation and struggle for four-year status, and the UTPB's unique features. The study was conducted by collecting data from available primary and secondary sources. The written data were then subjected to both external and internal criticism to determine the authorship and meaning of the documents. To explain events and put the written documents in context, oral histories, given by participants, were used. The educational opportunities offered by the UTPB have enriched the lives of Ector County citizens as well as the lives of many students from surrounding counties in the region of Texas known as the Permian Basin. Additional research topics related to the UTPB as well as other educational institutions are suggested.

An Empirical Analysis of Stock Market Anomalies and Spillover Effects: Evidence from the Securities Exchange of Thailand

Description: This study examines two interrelated but separate issues: cross-sectional predictability of equity returns in the Stock Exchange of Thailand (SET), and transmission of stock market movements. The first essay empirically investigates to what extent the evidence of three major documented stock market anomalies (earnings-price ratio, firm size, and book-to-market ratio) can be generalized across national stock markets. The second essay studies the price and volatility spillover effects from the New York Stock Exchange (NYSE) to the SET. The first essay, using the Fama-Macbeth procedure and the pooled time-series cross-sectional GLS regressions, finds a weak relation between the beta and average stock returns. The adjustment of estimated beta for the effect of thin trading does not change the implications of the results. Of the three anomalies investigated, the size effect has the most prominent and consistent role in explaining average returns. For the earnings-price ratio, the results indicate that the significance of the E/P ratio variable persists only if the nonfinancial firms are considered. In contrast to the previous empirical results for the U.S. and Japanese stock markets, the book-to-market ratio fails to explain the SET equity returns. The second essay employs a generalized autoregressive conditionally heteroskedastic (GARCH) model with conditional t-distributed errors to investigate the spillover effects. No evidence of price spillover effects is found for the full sample period. However, the spillover effects are significant during the period in which the Federal Reserve Board raised interest rates. Further examinations reveal that information inferred from price changes in the U.S. market influences only the opening price in the SET, not the open-to-close Thai stock market returns. This implies that price in the SET is informationally efficient with respect to the price determined in the U.S. stock market. The evidence is generally supportive of international financial integration and informational efficiency in ...
