Admission Factors Related to Success in Doctoral Programs in Vocational-Technical Education in Texas and Oklahoma

Description: This study identified the admissions criteria for selected doctoral programs in vocational-technical education in Oklahoma and Texas and investigated the relationship of these criteria to success in the doctoral programs. Success in the doctoral programs was identified in terms of cumulative doctoral grade point average. Data were obtained through a questionnaire designed to ©licit both general information concerning admissions criteria for vocational-technical doctoral programs at the selected institutions and to collect specific information on a random sample of twenty doctoral candidates from each of the four selected institutions. Factors considered included birthdates, gender, scores on admissions tests, grade point average in the masters program, the year the latest masters was completed, number of colleges attended, and cumulative doctoral grade point average. A statistical analysis using nine separate one-way analyses of variance determined that four of the nine factors considered proved to be statistically significant at the .05 level or better when correlated with the criterion variable (cumulative doctoral grade point average). Those factors were gender, Graduate Record Examination verbal and composite scores, and masters grade point average. The results of the study basically parallel findings of research concerning admissions criteria and success in graduate programs in other areas. Additional research efforts should address the issue of determining the most appropriate decision logic model for making admissions decisions in programs at the graduate levels.

Alcohol Use among the Elderly in Edmonton, Alberta: a Multivariate Analysis

Description: A model of social stressor variables, social integration variables and demographic control variables was tested to assess their impact on alcohol use among the elderly. A secondary analysis of a survey on alcohol use among the elderly in Edmonton, Alberta, Canada, was conducted to test the major hypotheses of the study. Contingency table analysis, using gamma and partial gamma as correlation coefficients, was utilized in the data analysis. The first hypothesis, in regard to the positive relationship of social stressors with alcohol use, was confirmed. The best predictors of alcohol use among the social stressor variables were usual occupation, length of retirement, annual income, and subjective health status. The second hypothesis, that the social integration variables would be negatively related to alcohol use, received only moderate support. The results of the analysis indicated that six of the ten social integration variables were negatively related to alcohol use. Only three of these variables, retirement status, religious participation, and marital status, were statistically significant. Hypothesis three also was not confirmed. The introduction of the social integration variables did not substantially decrease the strength of the relationship between social stressors and alcohol use. Gender and age were also introduced as control variables for the relationship between social stressors and alcohol use. Age had only a limited impact on the zero-order relationships. Gender demonstrated a strong relationship with alcohol use. Statistical analyses indicated that gender was the strongest predictor of alcohol use of all the variables in the analysis. The nature of the zero-order relationships of four of the six stressor variables changed when gender was controlled, and the partial relationships decreased in strength. It was suggested that future research on alcohol use among the elderly should focus on gender differences.

Alternative Funding Models for Public School Finance in Texas

Description: This study examined different funding methods for financing public education in order to solve the problems associated with large numbers of school districts and great disparities in property wealth without abandonment of property tax as the major revenue source. Using enrollment and State Property Tax Board data for the 1,061 school districts in Texas in 1986-87, four alternative funding plans were studied to compare the equity and fiscal impact of each on public school finance in Texas. The state and local shares of the total cost of education were computed using a combination of three per-pupil expenditure levels and four funding formulas. The per-pupil expenditure levels used were $3,850, $4,200, and $4,580. The formulas used were representative of a full state funding plan, a percentage equalization plan, a power equalization plan, and a foundation school program plan. Since each of the four plans used significantly higher per-pupil expenditure values, all required a greater monetary investment on the part of the state. However, all plans were found to be equalizing in nature if set per-pupil expenditure values were maintained and no local enrichment was permitted. In addition, each of the four plans, as studied, met the fiscal neutrality standard of the 1987 Edqewood v. Kirbv case. The percentage and power equalization plans required less monetary investment on the part of the state than either full state funding or the foundation school program. As a result of the study, it is recommended that the state consider a combination of plans. For example, the state could employ a full state funding model up to the $3,850 per-pupil expenditure level with added permissible local millage being limited and power equalized. In addition, while each of the plans studied reduces inequity, the increased cost of an adequate public school education suggests that the state consider ...

An Analysis as to the Causation of Leadership Style Based Upon Value System Determinants

Description: Leadership behavior has been a popular research topic for many years. Much of this research has focused upon the identification of leader behavior that is interactional or determined by the situation which influences leadership style. Current leadership theories raise the question of the relationships between leadership behavior and personal work values. The problem of this research is to investigate the relationship of leadership style with an individual's values for working. The purpose of this study is to examine the relationship between variables which characterize leadership styles and variables related to working values. The hypotheses hold that work values will correlate positively with leadership style. Data were collected through the administration of three research instruments to ninety-two managers of five business firms. The instruments were the participant cover letter providing demographic characteristics, Leader Behavior Analysis II identifying style of leadership, and Values for Working identifying personal work values. Coefficients of determination were calculated to identify possible relationships between leadership style and personal work values. No significant statistical correlation was found. The conclusion is that leadership style appears to be a function of something other than an individual's work values.

Analysis of Critical Skills Used By Educators of Students With Autism

Description: A review of the literature indicated that critical skills needed by educators of students with autism had not been sufficiently identified. Research efforts using survey instruments appeared to offer a method for gathering data in order to develop and analyze a comprehensive list of critical skills for educators of students with autism. A survey instrument was developed in bifurcate format that required respondents to rate 118 skill items according to Importance and Proficiency. Two Likert-type scales were provided to enable respondents to record their perceptions of Importance and Proficiency. The instrument was mailed to a nationwide stratified sample of educators of students with autism. A total of 90 surveys were mailed with 52 (57%) returned. Four hypotheses and two research questions were developed. Data were analyzed using MANOVA to test for significant differences among the four geographic regions of the United States and within ten skill areas. The findings did not support the hypotheses; therefore, all hypotheses were rejected. In further analysis utilizing the ANOVA and Chi-Square procedures, significant differences among some regions and within some of the skill areas were found. The findings suggest that educators from the four regions tended to differ in regard to Importance and Proficiency for certain skill items. Findings led to recommendations being given relevant to future research on critical skills needed for teachers in the field of autism.

Analysis of PAH and PCB Emissions from the Combustion of dRDF and the Nondestructive Analysis of Stamp Adhesives

Description: This work includes two unrelated areas of research. The first portion of this work involved combusting densified refuse derived fuel (dRDF) with coal and studying the effect that Ca(0H)2 binder had on reducing polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) emissions. The second area of work was directed at developing nondestructive infrared techniques in order to aid in the analysis of postage stamp adhesives. With Americans generating 150-200 million tons a year of Municipal Solid Waste (MSW) and disposing of nearly ninety percent of it in landfills, it is easy to understand why American landfills are approaching capacity. One alternative to landfilling is to process the MSW into RDF. There are technical and environmental problems associated with RDF. This work provides some answers concerning the amount of PAH and PCB emissions generated via the combustion of RDF with coal. It was found that the Ca(OH)2 binder greatly reduced both the PAH and the PCB emissions. In fact, PAH emissions at the ten-percent level were reduced more by using the binder than by the pollution control equipment. If the Ca(0H)2 binder can reduce not only PAH and PCB emissions, but also other noxious emissions, such as acid gases or dioxin, RDF technology could soon be the answer to the current landfill problems. The second portion of this work focused on developing a method to analyze stamp adhesives nondestructively. Using this method, it was fairly easy to differentiate among the three different types of adhesives that have been used by the United States Postal Service: gum arabic, dextrin, and polyvinyl alcohol. Differences caused by changes in chemicals added to the adhesives were also detected. Also, forgeries were detected with as much success, if not more, than by conventional methods. This work also led to the construction of equipment that allows large ...

The Analysis of the Accumulation of Type II Error in Multiple Comparisons for Specified Levels of Power to Violation of Normality with the Dunn-Bonferroni Procedure: a Monte Carlo Study

Description: The study seeks to determine the degree of accumulation of Type II error rates, while violating the assumptions of normality, for different specified levels of power among sample means. The study employs a Monte Carlo simulation procedure with three different specified levels of power, methodologies, and population distributions. On the basis of the comparisons of actual and observed error rates, the following conclusions appear to be appropriate. 1. Under the strict criteria for evaluation of the hypotheses, Type II experimentwise error does accumulate at a rate that the probability of accepting at least one null hypothesis in a family of tests, when in theory all of the alternate hypotheses are true, is high, precluding valid tests at the beginning of the study. 2. The Dunn-Bonferroni procedure of setting the critical value based on the beta value per contrast did not significantly reduce the probability of committing a Type II error in a family of tests. 3. The use of an adequate sample size and orthogonal contrasts, or limiting the number of pairwise comparisons to the number of means, is the best method to control for the accumulation of Type II errors. 4. The accumulation of Type II error is irrespective of distributions.

Antoine Reicha's Theories of Musical Form

Description: Antoine Reicha stands as an important figure in the growing systematization of musical form. While Traite de melodie (1814) captures the essence of eighteenth-century concern with tonal movement and periodicity, Reicha's later ideas as represented in Traite de haute composition musicale (1824-26) anticipate descriptions of thematic organization characteristic of his nineteenth-century successors. Three important topics emerge as crucial elements: melody, thematic development, and schematic categorization of complete pieces.

The Application of Guided Mental Imagery as an Instructional Strategy

Description: The primary purpose of this study was to compare regular classroom instruction which used Guided Mental Imagery (GMI) to a non-GMI teaching method. This comparison was expected to yield data which would provide insights relating to the potential of GMI as a useful and effective instructional strategy. Quasi-experimental research methods were followed. The experimental design was a modified "post-test only control group design." Two-hundred-four students in naturally occurring in tact classes formed the experimental and control groups. All groups received instruction in identical science/health content. Two parallel post-tests were administered to all students. Post-test "A" was given immediately after instruction to measure learning acquisition. Post-test "B" was given four weeks later to measure retention of learning. Means for test scores were grouped according to treatment and sub-grouped by the variables: IQ, handedness, identified learning disability, and intellectual giftedness. T_ tests for differences between independent means were conducted. Students' acquisition of basic academic content, when instructed with GMI methodology, was found to differ significantly from students' acquisition of the same content with non-GMI instruction. No statistically significant differences based on instructional methodology were found for content retention. The investigator concluded that GMI instruction may increase learning. Although measures of retention did not show significant differences between groups, a review of the mean scores revealed a minimal difference. This was interpreted to indicate equality of retention between the two methods. Recommendations for further investigation were offered. Post-testing of subjects at additional intervals, and increased training of students and teachers in GMI prior to collection of data were suggested.

Applications of GIS and remote sensing for the characterization of habitat for threatened and endangered species

Description: Geographic Information Systems (GIS) and remote sensing technologies were used to identify and describe potential habitat for three species endemic to the Southwestern United States; the Golden-cheeked Warbler (Dendroica chrysoparia), the Black-capped Vireo (Vireo atricapillus), and the Texas kangaroo rat (Dipodomys elator). For each species, the computerized classification of digital satellite imagery was integrated with ancillary spatial information (e.g. soils, geology, and land use) to construct a data base to be used for ecological evaluation as well as habitat protection and management measures.

Aqueous solubilities and water induced transformations of halogenated benzenes

Description: Methods of determining the aqueous solubilities of twelve chlorinated benzenes were evaluated in pure and in different water matrices. In pure water, results were comparable with the calculated values. Higher chlorinated tetrachlorobenzenes (TeCBs), pentachlorobenzenes (PCBz), and hexachlorobenzenes (HCBs) gave better precision and accuracy than lower chlorinated monochlorobenzenes (MCBs), dichlorobenzenes (DCBs), or trichlorobenzenes (TCBs).

Aspects of a Late Style in Sergei Rachmaninoff's Variations on a Theme of Corelli, Op. 42: a Lecture Recital, together with Three Recitals of Selected Works of J. Brahms, L. v. Beethoven, F. Chopin, C. Debussy, Zoltan Kodaly, M. Moussorgsky, and S. Prokofiev

Description: This document identifies elements of a stylistic change which occurred in several of the pieces Rachmaninoff wrote during the last years of his life. These elements reflect a progressive trend in his music, which certainly maintained in spite of the change, its characteristic sound. The Variations on a Theme of Corelli, Op. 42 illustrate these new developments in their lean, angular unison sonorities, stripped of chordal padding and virtuosic display, in their percussive, staccato and incisive ostinato rhythmic figures, astringent chromatic harmony and modern air of detachment. The Rhapsody on a Theme of Paganini, Op. 43 confirms this stylistic development in its remarkable similarity to the Corelli Variations. In the last twenty-six years of his life in exile from his homeland, making his way around the world as a concert pianist, Rachmaninoff wrote only six major works. Perhaps his increasing age, separation from homeland, and the musical revolutions surrounding him in the Western world produced this stylistic development.

Assessment of the Relationship of the Peer Assistance and Leadership (PAL) Program on the Self-Concept of At-Risk Students as Measured by the Piers-Harris Children's Self-Concept Scale

Description: The problem of this study was to determine if there was a difference in the self-concept of two groups of ninth-grade students when one group received the services of junior and senior students in a Peer Assistance and Leadership class. The results of the Piers-Harris Children's—Self—Concept Scale were used to determine the difference between the mean self-concept scores of the two groups and also to determine if there was a relationship between the criterion variable of the total self-concept score and eight predictor variables as identified by House Bill 1010: Limited English proficiency, age, school attendance, achievement scores two or more years below grade level in reading and mathematics on a norm-referenced test, failure to master any portion of the Texas Educational Assessment of Minimum Skills, failure in two or more subjects, grade retention, and eligibility for free or reduced-price lunch. A total of 105 students, 50 in the experimental group and 55 in the control group, participated. The findings revealed that there was no significant difference in the mean self-concept scores of the two groups. The correlation revealed that there were significant differences between self-concept and the variables of mathematics achievement scores, failing grades, and eligibility for free lunch.

The Association Between Computer- Oriented and Non-Computer-Oriented Mathematics Instruction, Student Achievement, and Attitude Towards Mathematics in Introductory Calculus

Description: The purposes of this study were (a) to develop, implement, and evaluate a computer-oriented instructional program for introductory calculus students, and (b) to explore the association between a computer-oriented calculus instructional program, a non-computer-oriented calculus instructional program, student achievement on three selected calculus topics, and student attitude toward mathematics. An experimental study was conducted with two groups of introductory calculus students during the Spring Semester, 1989. The computer-oriented group consisted of 32 students who were taught using microcomputer calculus software for in-class presentations and homework assignments. The noncomputer-oriented group consisted of 40 students who were taught in a traditional setting with no microcomputer intervention. Each of three experimenter-developed achievement examinations was administered in a pretest/posttest format with the pretest scores being used both as a covariate and in determining the two levels of student prior knowledge of the topic. For attitude toward mathematics, the Aiken-Dreger Revised Math Attitude Scale was administered in a pretest/ posttest format with the pretest scores being used as a covariate. Students were also administered the MAA Calculus Readiness Test to determine two levels of calculus prerequisite skill mastery. An ANCOVA for achievement and attitude toward mathematics was performed by treatment, level, and interaction of treatment and level. Using a .05 level of significance, there was no significant difference in treatments, levels of prior knowledge of topic, nor interaction when achievement was measured by each of the three achievement examination posttests. Furthermore, there was no significant difference between treatments, levels of student prerequisite skill mastery, and interaction when attitude toward mathematics was measured, at the .05 level of significance. It was concluded that the use of the microcomputer in introductory calculus instruction does not significantly effect either student achievement in calculus or student attitude toward mathematics.

The Association Between Systematic Exposure to Information About Computers and Attitude Changes Among Students Who Are Non-Computer Majors

Description: The problem with which this study is concerned is the association between systematic exposure to information about computers and attitude changes to computers among students who are non-computer majors. The experimental design includes a semester length course in introduction to computers at a small community college in Texas. The study has a twofold purpose. The first is to determine the pre-instruction direction and valence of attitudes of non-computer majors towards computers. The second is to determine the post-instruction direction and valence of attitudes of non-computer majors towards computers. A questionnaire was used to measure attitudes of students towards computers as a pre-test and post-test. The test results were encoded for computer statistical analysis. To determine the valence of changes in attitudes, chi-square tests were applied for each statement of the questionnaire with combinations between pre-test and post-test and each of the variables: gender, age, student performance, and instructor. To determine changes of direction in attitudes, a phi coefficient was applied for each statement of the questionnaire. The following conclusions may be drawn from the data collected for this study. 1. Based upon gender, age, student performance, and the variable of instructor, there was a significant difference in the valence of changes in attitudes towards computers. 2. Based upon gender, age, student performance, and the variable of instructor, there was no difference in the direction of change in attitudes towards computers.

Attitudes Toward the Contemporary Role of the Library Media Specialist in the Overall Elementary School Program in North Central Texas

Description: The purpose of this study, in addition to measuring and comparing attitudes of teachers, principals and library media specialists toward the role of the school library media specialist, was to identify and measure factors contributing to those attitudes. Nine factors were identified. Further path analysis revealed that the performance level of the library media specialist had the most influence on principals' and teachers' attitudes toward the Consultant, Technological and Instructional Roles. For principals and teachers, staff development had the most influence on attitudes toward the Management Role, while involvement in the school-wide program was most influential for library media specialists.

Beethoven's Transcendence of the Additive Tendency in Opus 34, Opus 35, Werk ohne Opuszahl 80, and Opus 120

Description: The internal unity of the themes in a sonata-allegro movement and the external unity of the movements in a sonata cycle are crucial elements of Beethoven's compositional aesthetic. Numerous theorists have explored these aspects in Beethoven's sonatas, symphonies, quartets, and concertos. Similar research into the independent variation sets for piano, excluding Opus 120, has been largely neglected as the result of three misconceptions: that the variation sets, many of which were based on popular melodies of Beethoven's time, are not as worthy of study as his other works; that the type of hidden internal relationships which pervade the sonata cycle are not relevant to the variation set since all variations are, by definition, related to the theme; and that variations were composed "additively," that is, one after another, without any particular regard for their order or relationship to one another. The purpose of this study is to refute all three of these incorrect assumptions. Beethoven was concerned with the order of variations and their relationship to one another, and he was able to transcend the additive tendency in a number of ways. Some of his methods included registral connection, registral expansion, rhythmic acceleration, textural expansion, dynamics, articulation, and motivic similarities. Chapter I contains a discussion of the role of the variation set in Beethoven's overall output. The teachers, composers, and works which may have influenced him are also discussed as well as his training in variation composition. Finally, those factors which Beethoven employed to unify his sets are listed and explained. Chapters II-V are devoted to detailed analyses of four striking variation sets: Opus 34, Opus 35, WoO 80, and Opus 120. Chapter VI presents a summary of the findings. It suggests that each of the sets investigated has a unique form and that each variation has a distinct place ...

The Beginnings of Music in the Boston Public Schools: Decisions of the Boston School Committee in 1837 and 1845 in Light of Religious and Moral Concerns of the Time

Description: The research problems of this dissertation were: 1) A description of the perceived value of music in light of political undercurrents in Boston prior to and during the years under investigation, and 2) the profile of the constituency of the Boston School Committee and Committee on Music in 1837 and 1845. Questions addressed the effect of religious and moral concerns of the day on the decision by the School Committee in 1837 to try music in the curriculum, and the possible effect of religious politics on Lowell Mason's dismissal from the schools in 1845. In the minds of mid-nineteenth century Bostonians, religious and moral values were intrinsic to the very nature of music. Key members on the School Committee portrayed music as being spiritual yet nonsectarian in its influence. Therefore, the findings suggest that music was believed to provide common ground between opposing and diverse religious sects. Reasons given for Mason's dismissal by John Sargent, a member of the Committee on Music, showed parallels to H. W. Day's accusations in the press a year earlier that Mason had managed his position in a sectarian manner. Sargent's background supports the theory that religious politics were at work in Mason's dismissal. Although members of the School Committee of 1845 were religious, only isolated cases support the proposition that any of them would have opposed Mason strictly on the basis of religious issues. Evidence suggests that their passivity to the action by the Committee on Music was probably due to concurrent public criticism of attempts at school reform within the Committee. While under such scrutiny, Committee members' inaction regarding Mason's dismissal may have reflected a desire not to jeopardize their own positions as a political body.
