Accounting Regulation and Information Asymmetry in the Capital Markets: An Empirical Study of Accounting Standard SFAS no 87
This study uses both basic and self-selection regression models to test three hypotheses about the effect of SFAS 87 disclosures on information asymmetry during 1985- 1987. Both types of models test the hypotheses after controlling for changes in the inventory holding and order processing costs of the spread, while the self-selection models also control for potential self-selection bias.

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

Multiresolution Signal Cross-correlation
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 History of the Bill J. Priest Institute for Economic Development of the Dallas County Community College District
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 …

The Appeal of Fashion Retailing as a Career: Perceptions of Fashion Merchandising Students
This study investigated the (1) relationship of students' family and educational background to their opinions of fashion retailing as a career, and (2) preferences for fashion retail job attributes in relationship the appeal of fashion retail job profiles. A sample of 131 fashion merchandising students from five state-funded universities completed a four-part survey which measured two independent variables: student background and preferences of fashion retail job attributes and two dependent variables: opinions of fashion of retailing as a career and the appeal of fashion retail job profiles. Analyses included multiple regression, t-test, and correlations. For opinions of fashion retailing as a career, parental background was not significant while attendance at a retailing course, semester hours completed and G.P.A. had limited relationships. Fashion retail job attribute preferences were related to the appeal of fashion retail job profiles; the most preferred attribute was high personal freedom.

Early Childhood Educators' Beliefs and Practices about Assessment
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 Monstrance: A Collection of Poems
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.

Relationship of Team Design and Maintenance on Performance and Satisfaction for Self-Directed Work Teams
Five models for designing work teams from the Work Group Design Measure (Campion & Medsker, 1992b) and the models7 relationships to effectiveness criteria were compared using 30 self-directed work teams (SDWTs) in a manufacturing/production setting of a large defense contractor. The models which are from social psychology, socio-technical systems theory, industrial engineering, and organizational psychology include Job Design, Composition, Context/Resources, Potency/Interdependence, and Process. The study also examined distinguishing demographics, team characteristics, and interpersonal processes within the teams that differentiate higher performing teams and/or teams with higher job satisfaction. Effectiveness criteria were performance and job satisfaction. Among the findings, four of the five team design models (i.e., excluding the Composition Model), and the team-oriented interpersonal group processes correlated with performance and SDWT member job satisfaction.

Transport Processes in Synchrotrons
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 …

The Implementation of Transition from Spanish Reading to English Reading Programs in Bilingual Classrooms
The purpose of this study was to describe the actual implementation of the transition process as observed in bilingual classrooms, and in particular, to examine the critical components (policy, curricular, and instructional characteristics) of the Spanish-to-English reading transition policies implemented in bilingual education programs in elementary schools in the Denton Independent School District in Texas. Four research questions drove this study. To investigate these questions, a multidimensional, descriptive research design was employed. The researcher used questionnaires, interviews, and field observations. The 11 educators, 6 bilingual teachers, 2 school-site principals, 2 school-site coordinators, and 1 district bilingual coordinator, were asked several types of questions (open response and closed response) using different types of instruments (questionnaires and interviews). Also, the six bilingual teachers were observed using two types of instruments (field notes and video tapes).

Depression and Heart Rate Variability in Patients with Coronary Artery Disease
Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

Orchestral Accompaniment in the Vocal Works of Hector Berlioz
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.

Factors Affecting Exercise Adherence among Participants, Nonparticipants and Dropouts of a Worksite Health and Fitness Program
This study examines the relationship between exercise adherence and several factors: self-motivation; attitudinal commitment; predisposing, enabling, and reinforcing (PER) factors; and barriers related to exercise. The sample (N=431) consists of employees at Texas Instruments, Incorporated in Dallas, Texas. The sample was placed into six comparison groups: high adherers, low adherers, nonparticipants who exercise, nonparticipants who do not exercise, dropouts who exercise and dropouts who do not exercise. Using a one-way ANOVA, the results show significance (p<.01) among the groups for: self-motivation and barriers. Attitudinal commitment and PER factors did not show significance. The results can be applied to worksite health programs to increase exercise adherence among employee populations.

Contours
Contours is scored for full wind ensemble and percussion, and is approximately nine minutes in length. The title refers to the way melodic shape or contour is used to create unity and variety in the piece. Contours is a single-movement work containing three sections that are unified by thematic and harmonic materials. The melodic material is generated by three twelve-tone rows, which are then used in combination with freely composed material. The first and last sections are highly contrapuntal and rhythmically disjunct. Both sections share common rhythmic and melodic patterns. These sections are contrasted with a slower and more lyric middle section. This section is made of a series of episodes that create an overall A-B-A structure.

Reciprocal Influences of Temperature and Copper on Fathead Minnows (Pimephales promelas)
Acclimation temperature had a significant effect on the lethality of copper to fathead minnows in replicated 96-hour lethality tests. Lowest median lethal copper concentrations (LC50) were recorded at 12 and 22°C, with LC50s at 5 and 32°C at least 140 μg/1 higher. This research found LC50 copper concentrations in the 300 to 500 μg/1 range and a polynomial relationship between LC50s and acclimation temperature. Following a 24-hour exposure to three sublethal concentrations of copper, critical thermal maxima (CTMax) were tested in minnows acclimated to four temperatures. Sublethal exposure to copper significantly decreased the CTMaxs relative to controls at three of the four temperatures. Control CTMaxs ranged from 28.6 to 40.4°C and increased 0.46°C for each 1°C increase in acclimation temperature.

The Wealth Effect of the Risk-Based Capital Regulation on the Commercial Banking Industry
The purpose of this study is to examine the wealth effect of the Risk-Based Capital (RBC) regulation on the U.S. commercial banking industry. The RBC plan was first proposed in January 1986, and its final form was announced on July 11, 1988. This plan resulted from dissatisfaction with the old capital regulation, which did not account for asset risk and off-balance sheet activities. The present study hypothesizes that the new regulation restricted bank optimal behavior and, therefore, adversely affected stock prices. The second and third hypotheses suggest that investors used company specific information, Net Tier 1 and Total risk-based capital ratios respectively, in valuing stocks of the affected bank holding companies. Hypotheses four and five suggest that abnormal returns are proportionally related to the levels of Net Tier 1 or Total RBC ratio. Both the traditional event study and the portfolio time-series regression, with RBC ratios (Net Tier 1 or Total) as the weight factors, are used in this study.

Biodiversity of Caddisflies (Trichoptera) of the Interior Highlands of North America
Caddisflies (Trichoptera) were collected from over 500 different locations throughout the Interior Highlands (Ozark, Ouachita, Arbuckle, and Wichita Mountains) between March 1990 and March 1994. I systematically sampled representative lotic and lentic habitats in 131 natural watersheds that comprise the 17 different physiographic subregions of this area. From my examination of approximately 60,000 specimens, surveys of regional museum collections, and review of literature records, I document 229 species distributed in 16 families and 58 genera. Included in this total are 27 endemic species and 15 new regional records. Descriptions are provided for a species new to science (Cheumatopsyche robisoni), four larvae (Helicopsyche limnella, H. piroa, Marilia species A, Polycentropus crassicornis) and a female (Helicopsyche piroa). Hydropsyche reiseni Denning, previously known only from the Arbuckle Mountains, is reduced in synonymy with H. arinale Ross. Further, I provide illustrated family, generic, and selected species-level keys that reflect this regional biodiversity.
