The Status of Transitional First Grade Programs in Regions 10 and 11 in North Central Texas

Description: The purposes of this study were to identify public school districts that currently offer, or are planning to offer, transitional first-grade programs, to describe existing transitional programs, to describe the genesis of transitional first-grade classes in the North Texas area, and to assist in the establishment of a networking system for schools in the North Central Texas area that currently have, or are planning to have, transitional first-grade classes. The 158 school districts in Regions 10 and 11 were surveyed. The findings of the study indicate that about one-third of the districts offered transitional first-grade programs during the 1988-89 school year, and two-thirds of the districts saw a need for transitional first-grade classes. These transitional programs were implemented to meet the needs of children who had completed kindergarten but were not ready for regular first grade. Transitional first-grade programs focus primarily on language arts and math skills for kindergarten and early first grade. While curriculum materials vary from district to district, language arts is likely to be based on a whole-language approach, and math is likely to focus on manipulatives.. Kindergarten teacher observation is used in the screening procedures in the majority of the districts. A number of instruments are used in the transitional screening process. The Gesell School Readiness Inventory, used in 24% of the districts, is most popular. About one-half of the districts use an informal method of evaluating the transitional program. A pretest-posttest method is used in 32% of the districts, and a longitudinal student tracking method is used in 20% of the districts. Of the 158 districts surveyed, 122, or 77%, of the districts are interested in being included in a networking system to exchange information about transitional first-grade programs.

The Development of Public Administration as a Field of Study in the Kingdom of Saudi Arabia

Description: The purpose of this study was to investigate the evolution and development of the field of public administration in the Kingdom of Saudi Arabia. Factors which brought about programs of public administration and which have been influential in the development of these programs were analyzed. Although the historical roots of Saudi public administration are traced to the recapture of Riyadh by the late King Abdulaziz Al-Saud in 1902, modern public administration in the Kingdom actually began in 1953 with a royal decree which established the Council of Ministers. Factors that led to the establishment of the Institute of Public Administration and the birth of public administration programs at major Saudi universities include the country's rapid socioeconomic growth, rapid administrative expansion, and policies of administrative reform, higher education development, and the ambitious Five-Year Plans. Despite the fact that attention to the field of public administration in the Kingdom of Saudi Arabia dates back to the establishment of the College of Commerce at King Saud University in 1959, the real start of teaching public administration in Saudi universities is considered recent. The field of public administration is paralleled with the establishment of the Departments of Public Administration in King Abdulaziz University in 1971, followed by similar steps at King Saud University in 1978. This study revealed that the Saudi Institute of Public Administration and institutions of higher education offering programs of public administration have played a highly influential role in the development of public administration in the Kingdom. However, current research in the field and practice of public administration at the university level is narrowly focused on faculty promotion. The research conducted for this study did not clarify the degree to which efforts are being made to bring theory closer to actual practice. However, a greater need for coordination between university-based public ...

The Development of the University of the Thai Chamber of Commerce, Bangkok, Thailand

Description: The purpose of this study was to describe the development of Thailand's oldest private university, the University of the Thai Chamber of Commerce, Bangkok, Thailand, from 1963 to 1987. This historical research used records and documents which are primary sources from the University of the Thai Chamber of Commerce and the Association of Private Higher Education Institutions of Thailand together with interviews with the chairman of the Thai Chamber of Commerce, president, faculty and staff of the University of the Thai Chamber of Commerce. Secondary sources were reports and publications from the Ministry of University Affairs and libraries in Thailand. The areas of emphasis in the study were government policies on private higher education, legislation that initiated the founding of the University, the founder, the university's goals, the university's organizational structure, financial sources, admission policies, physical plants, programs, faculty and students. 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. The university of the Thai Chamber of Commerce was founded by the Thai Chamber of Commerce with the purpose of training Thai students for the business sector and promoting the economic stability of the nation. The university's organizational structure is centralized and is self-supporting. The university strives for academic excellence, and thus supports the development of the nation. Suggestions for further study include: (a) the study of private higher education institutions which were established with all of the various fields of study in place, and (b) a study to identify factors that will contribute to the future development of the university of the Thai Chamber of Commerce and other private universities in Thailand.

The Contrast-Inertia Model and the Updating of Attributions in Performance Evaluation

Description: The two problems which motivate this research concern the role of managerial accounting information in performance evaluation. The first problem is that the processing of accounting information by individual managers may deviate from a normative (Bayesian) pattern. Second, managers' use of accounting information in performance appraisal may contribute to conflict between superiors and subordinates. In this research, I applied the contrast-inertia model (C-IM) and attribution theory (AT) to predict how accounting information affects managers' beliefs about the causes for observed performance. The C-IM describes how new evidence is incorporated into opinions. Application of the C-IM leads to the prediction that information order may influence managers' opinions. Attribution theory is concerned with how people use information to assign causality, especially for success or failure. Together, the C-IM and AT imply that causal beliefs of superiors and subordinates diverge when they assimilate accounting information. Three experiments were performed with manufacturing managers as subjects. Most of the subjects were middle-level production managers from Texas manufacturing plants. The subjects used accounting information in revising their beliefs about causes for performance problems. In the experiments, the manipulated factors were the order of information, subject role (superior or subordinate), and the position of different types of information. The experimental results were analyzed by repeated measures analyses of variance, in which the dependent variable was an opinion or the change in an opinion over a series of evidence items. The experimental results indicate that the order of mixed positive and negative information affects beliefs in performance evaluation. For mixed evidence, there was significant divergence of opinions between superiors and subordinates. The results provide little evidence that superior and subordinate roles bias the belief updating process. The experiments show that belief revision in performance evaluation deviates from the normative standard, and that the use of accounting information may ...

Effects of Water Quality, Instream Toxicity, and Habitat Variability on Fish Assemblages in the Trinity River, Texas

Description: The Trinity River flows through the Dallas-Ft. Worth Metroplex in north central Texas where it receives effluents from numerous point sources including seven large regional wastewater treatment facilities. Historically, the Trinity River has been impacted by massive wastewater loadings which often constitute > 80% of the total river discharge during low flow periods. Normally, high mass loadings correspond to the summer months, compounding the effects of a naturally stressful period, characterized by high temperatures and low dissolved oxygen concentrations. Samples from 12 stations were collected quarterly over an 18 month period from the Trinity River and two tributaries. Water samples were analyzed for a variety of water quality variables, including metals, priority pollutants, pesticides, and general water quality parameters. Water samples were also tested for acute and subchronic effects with several test species. Fish were collected at each station and assemblages were characterized using traditional classification techniques and the Index of Biotic Integrity. In addition, sediment samples were assessed for toxic effects which could have adversely impacted fish recruitment and in situ biomonitoring experiments were performed. Quantitative habitat characterization analyses were performed to gain additional information that could possibly explains differences in fish assemblage structure related to habitat variability. Data were analyzed using regression, univariate, multivariate, and descriptive statistical techniques and new approaches for analyzing impact assessment data were discussed. Results indicated that the most substantial impacts on fish assemblages were confined to a segment of the river where a sequence of point sources, in close proximity to each other, were overloading the river's capacity to sufficiently dilute and/or detoxify the effluent. Data also indicated the presence of episodic toxicity from nonpoint sources. In addition, toxic effects in sediment samples and differences in habitat were detected and may have contributed to measured differences among fish assemblages in the Trinity River.

The Impact of Extracurricular Activities on the High School Academic Achievement of Average and Below Average Students During the Implementation of the Texas No Pass-No Play Rule (1983-1986)

Description: The State of Texas implemented the No Pass-No Play Rule within House Bill 72 in the spring semester of 1985. The addition of this section to the state education code was a part of the state's efforts toward educational reform. The perceived rationale implied in House Bill 72 is that extracurricular activities can inspire student motivation and increase student achievement. The No Pass-No Play Rule seems to imply that there is a relationship between student achievement and extracurricular activities, and further implies that a student can be motivated to achieve by the desire to continue to participate in extracurricular activities. The problem of this study was a comparison of academic achievement for high school pupils involved in extracurricular activities and those who did not participate in extracurricular activities under the Texas No Pass-No Play Rule. The purpose of this study was to determine the impact of extracurricular activities on the academic achievement of high school students, specifically looking at the years 1983 through 1986, when the No Pass-No Play Rule was implemented. This study was an ex post facto study with data obtained from a cooperating Texas school district. Students were matched on critical variables, and their scores on a measure of achievement were analyzed to determine if there was any relationship between extracurricular activities and achievement. Repeated measures of achievement were also analyzed to determine if students involved in extracurricular activities scored differently from those not involved in extracurricular activities over this time period in which the No Pass-No Play Rule was implemented. Results indicated that for those students involved in this study, there was no significant difference on a measure of achievement for students involved in extracurricular activities and those who did not participate. Results also indicated that in the years 1983 through 1986 all students involved in ...

Role of Selected Variables on Organizational Commitment in Selected Organizations in a North Texas Metropolitan Area

Description: This study investigated the role of selected variables on organizational commitment in selected organizations in a North Texas metropolitan area. The selected (independent) variables were orientation attendance, unit size, educational level, gender, age, and length of service. Organizational commitment score was the dependent variable. The Organizational Commitment Questionnaire and a demographic questionnaire were administered to 1,055 employees. The Organizational Commitment Questionnaire contained fifteen statements which measured employees' feelings about their organization. Multiple regression was used to determine the relationship between organizational commitment and the selected variables at the .001 level of significance. It was determined that gender and length of service showed the strongest significant relationship on organizational commitment. This model shows that the six independent variables account for only 3 percent of the variance in the relationship between organizational commitment and the selected variables. Therefore, approximately 97 percent of the unexplained variance is accountable for the organizational commitment of the employees at the selected organizations used in this study. Studies using the Organizational Commitment Questionnaire to show the relationship between organizational commitment and other antecedents of organizational commitment are recommended. A follow-up study should also be conducted using the Organizational Commitment Questionnaire to show the relationship between organizational commitment and race. A follow-up study should be conducted using this questionnaire and a work ethic questionnaire to determine the relationship between organizational commitment and work ethics. An orientation attendance questionnaire should be developed and used with the Organizational Commitment Questionnaire to show the relationship between organizational commitment and orientation attendance. Additional research is necessary in other organizations and cultural settings before this study can be generalized to a greater number of employees. Recommendation is made that future researchers administer questionnaires to subjects due to the low reading and comprehension skills of many respondents.

Media Agenda-Building Effect: Analysis of American Public Apartheid Activities, Congressional and Presidential Policies on South Africa, 1976-1988

Description: The mass media's role in informing the American public is critical to public support for government policies. The media are said to set the national agenda. This view is based on the assumption of selective coverage they give to news items. Media coverage also influences the salience the public attaches to issues. However, media agenda effect has been challenged by Lang and Lang (1983). These scholars, in their media agenda-building theory, argued that the success of media effect on national agenda is dependent on group support. In order to test this theory, time-related data on South Africa crises, media coverage"of South Africa, American public reactions, congressional, and presidential apartheid-related activities, between 1976 and 1988, were analyzed. Congressional anti-apartheid policies were the dependent and others, the independent variables. The theory made analysis of the data amenable to the additive adopted to test for the significance of the interactive variables, indicated that these variables were negatively related to congressional anti-apartheid policies. The additive model was subsequently analyzed. The time series multiple regression analysis was used in analyzing the relationships. Given autocorrelation and multicollinearity problems associated with time series analysis, the Arima (p, d, q) model was used to model the relationships. This model was used to indicate support, or nonsupport, for the time series regression analysis. The result of the additive model indicated that South African political crises were negatively related to congressional anti-apartheid actions. It also showed that the relationship between the American public reactions and congressional anti-apartheid policies was greater in comparison to all other independent variables. The presidential actions taken against South Africa were negatively related to Congress' anti-apartheid actions. Television had the greatest relationship with congressional anti-apartheid actions compared to newspapers and magazines.

A Study of the Relationship Between Motive and Structure in Brahms's op. 51 String Quartets

Description: In 1873, Brahms completed the two op. 51 quartets. These were not the first string quartets Brahms composed, hut they were the first that Brahms allowed to be published. He found the string quartet difficult; as he confided to his friend Alwin Cranz, he sketched out twenty string quartets before producing a pair he thought worthy of publishing. Questions arise: what aspect of the string quartet gave Brahms so much trouble, and what in the op. 51 quartets gave him the inclination to publish them for the first time in his career? The op. 51 quartets are essential to understanding the evolution of Brahms's compositional technique. Brahms had difficulty limiting his massive harmony and polyphony to four solo strings. This difficulty was compounded by his insistence on deriving even the accompaniment from the opening main motivic material. This study investigates the manner in which Brahms distributes the main motivic material to all four voices in these quartets, while at the same time highlighting each voice effectively in the dialogue.

Studies of the Mechanism of the Catalytic Subunit of cAMP Dependent Protein Kinase

Description: The kinetic mechanism of the cAMP-dependent protein kinase has been determined to be random in the direction of MgADP phosphorylation by using initial velocity studies in the absence and presence of the product, phospho-Serpeptide (Leu-Arg-Arg-Ala-Ser[P]-Leu-Gly) , and dead-end inhibitors. In contrast to the kinetic parameters obtained in the direction of Serpeptide phosphorylation, the only kinetic parameters affected by Mg^2+ are the dissociation constants for E:phospho-Serpeptide and E:MgADP, which are decreased by about 4-fold. The dead-end analog MgAMPCP binds with an affinity equal to that of MgADP in contrast to MgAMPPCP, which binds weaker than MgATP. The ratio of the maximum velocities in the forward and reverse reactions is about 200, and the Haldane relationship gives a K-eq of (7.2 ± 2) x 10^2. The latter can be compared to the K-eq obtained by direct measurement of reactant concentrations (2.2 ± 0.4) x 10^3 and 31-P NMR (1 ± 0.5) x 10^3. Data for the pH dependence of kinetic parameters and inhibitor dissociation constants for the cAMP dependent protein kinase are consistent with a mechanism in which reactants selectively bind to an enzyme with the catalytic base unprotonated and an enzyme group required protonated for Ser-peptide binding. Preferentially MgATP binds fully ionized and requires an enzyme residue (probably lysine) to be protonated. The maximum velocity and V/K-MgATP are pH independent. The V/K for Serpeptide is bell-shaped with estimated pK values of 6.2 and 8.5. The dependence of 1/K-i for Leu-Arg-Arg-Ala-Ala-Leu-Gly is also bell-shaped, giving pK values identical with those obtained for V/K-Serpeptide, while the K-i for MgAMPPCP increases from a constant value of 650 μM above pH 8 to a constant value of 4 mM below pH 5.5. The K-i for uncomplexed Mg^2+ obtained from the Mg^2+ dependence of V and V/K-MgATP is apparently pH independent.

A Study of the Relationship between Field-Independent and Field-Dependent Cognitive Styles and Social Behaviors during Free-Play of Preschool Children

Description: The problem of this study was to discover the relationship between field-independent and field-dependent cognitive styles and social behaviors during free-play of preschool children in a school setting. This study also compared the field-independent and field-dependent cognitive styles and social behaviors during free-play between age-groups and sex-groups. Thirty-six children from a university child development laboratory were subjects. They were selected from a 3-year-old classroom and a 4-year-old classroom. The research instrument, the Preschool Embedded Figures Test, was utilized to measure field-independent and field-dependent cognitive styles. The children's social behaviors were observed during free-play for four consecutive weeks. The nine categories of social behavior were solitary, parallel, and group play; .unoccupied, onlooker, transitional, and aggressive behaviors; and conversations with teachers and conversations with peers. Correlations between field-independent and field-dependent cognitive styles and social behaviors indicated that field-independence/field-dependence was related to social orientations in preschool children and also related to the choice of play activity. Field-dependent children tended to engage in conversations with teachers more often than field-independent children. Four-year-old children who were field-independent tended to spend more time in solitary play than 4-year-old children who were field-dependent. Four-year-old boys who were field-independent tended to play more often in the manipulative learning center than 4-year-old boys who were field-dependent. There were significant differences between age-groups but not significant differences between sex-groups in field-independence/field-dependence. Some social behaviors were significantly different between age-groups and sex-groups. Three-year-old children participated significantly more in physically aggressive behavior and less in conversations with peers than 4-year-old children. Boys engaged significantly more in aggressive behavior than girls.

Orfeo I: an Analytic Investigation of Thea Musgrave's Work for Flute and Tape, with Performance Guide

Description: This comprehensive study of Thea Musgrave's Orfeo I is the basis for a lecture-recital performed on March 20, 1989, at the University of North Texas, as part of DMA dissertation requirements. It includes: brief bio-background of Musgrave and Orfeo; historical background of both the Orpheus legend and some landmark dramatic works based on it; general development of Musgrave's dramatic language and specific ways in which she uses it in this composition; analysis of the work; performance guide; and annotated appendix listing Musgrave's published and recorded chamber works which include flute. Orfeo I is a major work for flute and electronic tape comprised entirely of manipulated flute sounds. It was commissioned by the British Broadcasting Corporation for James Galway, who recorded the taped material and was the featured performer in the 1976 London premier. An alternate version, Orfeo II, with fifteen strings in place of electronic tape, was premiered by David Shostac in 1976 in Los Angeles, and conducted by the composer. Orfeo's form is programmatically designed, divided into six sections based on Musgrave's "Scenario"of the Orpheus myth. Characters are dramatically depicted through means of "motifs"; that of Orpheus in solo flute, and all others in tape sounds. Musgrave uses quotations from Gluck's opera, Orfeo ed Euridice and Stravinsky's ballet, Orpheus, as basic compositional models. Using her own harmonic language, she combines tonal and chromatic elements in a linear compositional style which ties flute and tape together. Through "controlled aleatory," the soloist is allowed to shape certain aspects of the work. Use of electronic tape places Orfeo I in the realm of intermedia. In addition, Musgrave offers a versatile range of performance possibilities, from highly dramatic (including lighting instructions, option of ballet choreography for solo male dancer, costuming, etc.) to a straight concert rendition.

Pyrolysis Capillary Chromatography of Refuse-Derived Fuel and Aquatic Fulvic Acids

Description: Pyrolysis-capillary gas chromatography combined with FID, ECD and MS detection were used to characterize refuse-derived fuel and aquatic fulvic acids. Different pyrolysis methods and programs were evaluated. Pyrolysis temperatures of 700-800°C produced the strongest signal for organics present in RDF and fulvic acid. Cellulose and fatty acids pyrolyzates were identifiable by GC-MS following preparative pyrolysis fractionation. At organic chloride content of 0.023%, only three halogenated compounds were detected in the GC-MS of the fractions. None of the priority pollutants were detected at lower detection limit of 0.72 to 24 mg/ kg RDF. Selective solvent extraction improves the reproduciblities of the technique and allows the detection of polymeric structures. Pyrograms of polyvinyl chloride and regular typing paper showed some common peaks that are present in the RDF pyrogram. About 65% of the peaks in the RDF pyrogram might be of paper origin. The organic chloride content of the RDF was evaluated by ion chromatography of the trapped pyrolyzates in 2% NaOH trap and it was found to be 221 mg Cl/ kg dry RDF. Pyrolysis conditions and temperature programs for FA were systematically evaluated. Samples included purified FA, methylated FA and HPLC separated fractions. Characteristic pyrograms were developed. Profiles of benzene, toluene, phenol, m-cresol and biphenyl from FA were evaluated. The production of phenol was the largest at 800°C, at concentration of 1.61 mg per gram of FA pyrolyzed. The profiles of benzene and toluene followed the same pathways. Both pyrolyzates had at least two precursors. HPLC fractions of FA showed some regular retention patterns characteristic of polymeric material. DL-proline, seriene and vanillic acid pyrograms showed some peaks with the same retention times as those in FA pyrogram under the same conditions. A reproducibility of 6% relative standard deviation was achieved in the pyrolysis of RDF and 0.91% in the case ...

Detection of the Resonant Vibration of the Cellular Membrane Using Femtosecond Laser Pulses

Description: An optical detection technique is developed to detect and measure the resonant vibration of the cellular membrane. Biological membranes are active components of living cells and play a complex and dynamic role in life processes. They are believed to have oscillation modes of frequencies in the range of 1 to 1000 GHz. To measure such a high-frequency vibration, a linear laser cavity is designed to produce a train of femtosecond pulses of adjustable repetition rate. The method is then directly applied to liposomes, "artificial membrane", stained with a liphophilic potential sensitive dye. The spectral behavior of a selection of potential sensitive dyes in the membrane is also studied.

Commonalities Among Women Superintendents in Texas

Description: The major purpose of this descriptive study was to determine common characteristics and influences among women who were serving as public school superintendents of independent districts in Texas during the 1988-89 school year. Commonalities were determined in (1) personal characteristics, (2) personality traits, and (3) perceived barriers to career mobility. A seventy-item survey was developed, validated, and mailed to the thirty-three women superintendents in Texas. Data from the survey were analyzed to determine if commonalities existed among women superintendents. Based on the findings of this study, the following conclusions seem justified: (1) Commonalities in personal characteristics which exist among women superintendents include age, ethnicity, marital status, parenthood, positive attitudes toward being both mothers and superintendents, preference for husbands in the field of education, demonstration of early leadership traits, and self-perceptions of being assertive and risk-taking; (2) Most women superintendents share common views on subjective measures concerning their own personalities, and they rated themselves highest in areas which include self-esteem, general daily activity level, independence, job satisfaction, ability to operate under pressure and practicality; and (3) Most women superintendents perceive similar internal and external barriers to their career mobility; a lack of professional network and employers' negative attitudes toward women are the most common external barriers.

Romanzas for Clarinet and Piano by Ernesto Cavallini: A Lecture Recital Together with Three Other Recitals

Description: The lecture was given on September 25, 1989. The discussion dealt with the stylistic characteristics of music for clarinet by Ernesto Cavallini and included a performance of four romanzas: La Calma, Un Pensiero, L'Incudine, and Lontano dalla Patria. Cavallini was the foremost clarinet virtuoso of the nineteenth century as well as a prolific composer of music for his instrument. The works presented in the lecture represent Cavallini's proclivity for a performance style combining virtuosity with lyrical expression. Copies of the original publications of Cavallini's romanzas were obtained from the Biblioteca del Conservatory, "Giuseppi Verdi," Milan, Italy. In addition to the lecture recital, three other recitals for solo clarinet were given. The first recital was given on October 29, 1984, and included works by Carl Maria von Weber, Leslie Bassett, Halsey Stevens, and Carl Reinecke. The second recital was given on July 29, 1985, and included works by Bernard Heinrich Crusell, Halsey Stevens, and Johannes Brahms. The third recital was given on October 3, 1988, and included works by Saviero Mercadante, Eugene Bozza, and John Ireland. All four recitals were recorded on magnetic tape and are filed, along with the written version of the lecture materials, as a part of the dissertation.
