The problem of this study is to determine the vitamin B-6 status of patients who have chronic obstructive pulmonary disease (COPD). Erythrocyte aspartate transaminase assay was the method for measuring vitamin B-6 status. The vitamin B-6 status was examined in thirty subjects (ten COPD subjects and twenty control subjects). An unpaired t-test was used to compare the vitamin B-6 status of the COPD group versus the control group. Four determinants (percentage stimulation, ratio of basal to stimulated activity, basal activity, and stimulated activity) were used to determine vitamin B-6 status in both groups of subjects. Percentage stimulation and ratio of basal to stimulated activity were not significantly different (control group versus COPD group) at the .05 level. However, two of ten COPD subjects had values for percentage stimulation that were two standard deviations above the mean, indicating a poor B-6 status. In contrast, basal activity and stimulated activity of erythrocyte aspartate transaminase were found to be significantly lower at the .05 level in the COPD group than the control group. Therefore, the COPD subjects as a group had some biochemical characteristics of a lower level of vitamin B-6 than the controls.

The main purpose of this study was to determine the effect of Texas House Bill 72 on equalization of finances in the public school districts of Texas. House Bill 72 is a finance reform bill which was passed by the Texas Legislature during the Summer of 1984. This study involves basically three steps. First, current criteria for equity as defined by school finance "experts" and recent definitive court decisions were determined. Second, financial data from the Texas Education Agency were statistically analyzed for the 1984-1985 school year. Third, the statistical analysis was used to determine if the current Texas school finance plan meets the current criteria for equity. The population used in the study was 1,068 school districts. Based on the findings of this study the following conclusions were drawn. 1. The use of a per capita flat grant by the Texas Public School Finance System contributes to the unequalizing of financial resources available to school districts. 2. School districts with greater property index values are required to exercise very little effort toward the support of their public schools. 3. School districts with high property index values tend to have lower effective tax rates and high per-pupil expenditures. 4. School …

There are 150 million tons of Municipal Solid Waste (MSW) annually produced in the United States, which is approximately equivalent to 150 million barrels of oil. MSW production is inexhaustible, and is increasing on an annual per capita basis of approximately three per cent. After controlling the moisture and adding a binder, the combustible portion of MSW was converted to pellets. The objects of this project were to 1) evaluate the binder, 2) prepare the pellets, and 3) evaluate the pellets with regard to density. The manufacture of pellets was conducted at the Naval Air Station, Jacksonville, Florida. The evaluation of the binders and the pellets was done at North Texas State University (NTSU). There were three procedures for measuring the density. The first, using water displacement, was from the American Society for Testing and Material (ASTM). The second, using wax coating, was also from ASTM. The third, using sharply-cut cylindrical pellets, was developed at NTSU.

This dissertation deals with the problem of manipulating and storing an image using quadtrees. A quadtree is a tree in which each node has four ordered children or is a leaf. It can be used to represent an image via hierarchical decomposition. The image is broken into four regions. A region can be a solid color (homogeneous) or a mixture of colors (heterogeneous). If a region is heterogeneous it is broken into four subregions, and the process continues recursively until all subregions are homogeneous. The traditional quadtree suffers from dependence on the underlying grid. The grid coordinate system is implicit, and therefore fixed. The fixed coordinate system implies a rigid tree. A rigid tree cannot be translated, scaled, or rotated. Instead, a new tree must be built which is the result of one of these transformations. This dissertation introduces the independent quadtree. The independent quadtree is free of any underlying coordinate system. The tree is no longer rigid and can be easily translated, scaled, or rotated. Algorithms to perform these operations axe presented. The translation and rotation algorithms take constant time. The scaling algorithm has linear time in the number nodes in the tree. The disadvantage of independent quadtrees is …

This study examines the effect of class discussion as a pre-writing activity on actual writing performance. The experiment was conducted with all the Level 3 and Level 4 students enrolled in the Intensive English Language Institute of North Texas State University in the Spring, 1986 semester. Cochrans C test was performed to test significant differences between groups at the beginning of this test. Multivariate analysis of variance tests were used to determine the treatment effect between and within groups, and a matched t-test was also utilized to analyze the difference within tests. Pearson product moment correlation coefficient was calculated to determine the relationship between the discussion activity score and the actual writing score. Analysis of covariance tests were used to determine which variance of discussion activities had greater effect on the actual writing score.

The opinions of individuals may be influenced by groups of different gender configurations. This influence was studied by asking college students to respond to a series of statements in pretest and post-test settings. Post-test settings included the use of manipulatively constructed confederate groups to influence the subjects' responses. A pretest was administered in an anonymous nonthreatening environment. Within a week, the subjects were post-tested in a setting with four "confederates" who had previously been instructed to unanimously voice opposite answers to the subjects' initial responses to pretest questions. The objective of this experiment was to determine the number of opinions that were changed when confronted with opposing views. Change of opinions between pretest and post-test were considered to be operational definitions of "conformity."

Because international students are an increasingly significant aspect in American colleges and universities and on the North Texas State University campus in particular, this study was undertaken to explore the intercultural clash which Thai students at North Texas State University experience. Twenty-two Thai students were interviewed in depth using the oral history method. Ten faculty and administrators who work with international students were interviewed concerning their observations of Thai students. The information gleaned from these thirty-two interviews and from an examination of the basic socio-cultural differences between Thailand and the United States resulted in the isolation of the following basic difficulties. 1. Thais do not have command of written and oral English. 2. Americans do not have an appreciation of foreigners and lack tolerance in everyday exchanges with them. 3. Thais avoid becoming involved in American society. 4. Thais are not efficiently prepared for the American classroom. 5. American instructors do not appear prepared to handle the problems of Thai students. The study also developed a number of suggested solutions: 1. Raise the consciousness of Americans concerning Thai students; 2. Provide more effective ways of improving oral and listening skills in the English proficiency of Thai students beginning with American-directed …

The purpose of this study was three-fold: 1. To determine the amount and direction of changes in sources of funding for the Regional Education Service Centers from 1979 to 1984. 2. To determine the percent of change in programming expenditures of the Regional Education Service Centers from 1979 to 1984. 3. To rate the changes in quality of programming as perceived by the superintendents of the local school districts receiving services from 1979 to 1984. A review of the literature and a brief history of the Regional Education Service Centers of Texas were followed by tabular and narrative descriptions of the findings. Deflated data, to account for inflation, were derived by applying Bureau of Labor statistics formulas to dollar amounts supplied by the Regional Education Service Centers. Each of the five Education Service Centers included in the study experienced a decrease in total funds, due chiefly to a cut in federal and state support. Although local contributions increased in four out of five of the Regions during the five-year period, the net result to the Centers was a decrease in funding ranging from 23.2 percent to 51.8 percent. The impact on programming was severe. Of the nine major services on …

The effects of gold sodium thiomalate (GST) on murine spleen cells were investigated using in vitro mitogen blastogenesis techniques. Addition of GST to intact spleen cells resulted in a decreased blastogenic response to the T cell mitogen, concanavalin A (Con A). Thymidine uptake of spleen cells depleted of macrophages and cultured with Con A and GST demonstrated biphasic effects. At 2.5 pg Con A/ml, blastogenesis of macrophage depleted spleen cells was inhibited to a lesser degree than intact spleen cells; whereas, at 0.5 pg Con A/ml, the macrophage depleted spleen cells were inhibited to a greater degree than the intact spleen cells. Addition of GST at intervals ranging from 0 to 48 hours indicated that inhibition occurred within 36 hours following mitogen stimulation. These results suggest that GST inhibits early events of lymphocyte activation by direct interaction with lymphocytes.

The purpose of this study was to determine the role of high school assistant principals as perceived by principals, assistant principals, and teachers. The population in this study consisted of the principals, assistant principals, and teachers in Class 5A high schools in Texas during the 1985- 86 school year. One hundred and twenty of the Class 5A high schools were randomly selected to participate in the study. One principal, one assistant principal, and one teacher from each school were asked to respond to the survey. A questionnaire was designed to measure the perception of the three groups under study and contained seventy-seven job responsibilities which were divided into six major areas. The six areas were school management, staff personnel, community relations, student activities, curriculum and instruction, and pupil personnel. Eighteen items were eliminated through clarity, appropriateness, and reliability studies. Each respondent was asked to rate the degree of involvement of assistant principals for each job responsibility listed in two columns labeled current and ideal. Five hypotheses were developed for the study. Three hypotheses were tested by a multivariate one-way analysis of variance with repeated measures, and two were tested using a univariate one-way analysis of variance. The .05 level of …

This study examined the relationship between the resistance to temptation of three-, four-, and five-year-old children and parental attitudes toward child-rearing. Other variables explored included gender of the children, employment status of mothers, and socio-economic status of families. Fifty-two three-, four-, and five-year-old children from two centers were tested to determine their levels of resistance to temptation as measured by Grinder's Bean Bag Instrument. Parental attitudes toward child-rearing were measured by Schaefer and Bell's Parental Attitude Research Instrument (PARI). To determine the difference between the resistance to temptation scores and socio-economic status, gender, and employment status of mothers, Jt tests were employed. No significant differences were found with regard to these variables. Factor analysis of the PARI resulted in three primary factors: Hostility-Rejection, Authoritarian- Control, and Democratic-Attitude. To determine the difference between the Hostility-Rejection scores, Authoritarian-Control scores, and Democratic-Attitude scores of the mothers and socio-economic status, _t tests were employed. There were no significant differences between mothers of a lower socio-economic level and their Hostility- Rejection and Democratic-Attitude scores. However, mothers of a lower/upper socio-economic level showed significantly higher levels of Authoritarian-Control than mothers of an upper socio-economic level. To determine the difference between the Hostility-Rejection scores, Authoritarian- Control scores, …

Domenico Gabrielli's seven trumpet sonatas are among seventeenth-century trumpet repertoire predominant in the instrumental tradition of the basilica San Petronio, which flourished roughly from the election of Maurizio Cazzati as maestro di cappella in 1657 until the dissolution of the orchestra of the church in 1695. Fostered by numerous occasions for performance, the Bolognese trumpet works tend to exhibit a uniform musical style imposed by musical academies. After a discussion of the probable cause of the termination of the instrumental tradition and of the role of musical academies, this paper will be primarily concerned with formal aspects of fast movements of Gabrielli's sonatas. Despite the fact that the predominant organizing principle of the fast movements appears to be textural, a step toward ritornello form is taken in some of the movements, in which tutti and solo sections are independently developed. In particular, the recurrence of identical material in tutti confirming different keys, the thematic relation between tutti and solo, and the symmetrical and balanced tonal plan are unmistakable seeds of full ritornello form. The text is followed by critical notes and transcriptions of the seven sonatas.

Two phage lambda clones encompassing human tRNA genes have been isolated from a human gene library harbored in bacteriophage lambda Charon-UA. One of the clones (designated as hLeuU) containing a 20-kb human DNA fragment was isolated and found to contain a cluster of four tRNA genes. An 8.2-kb Hindlll fragment encompassing the four tRNA genes was isolated from the 20-kb fragment and subcloned into pBR322 for restriction mapping and DNA sequence analysis. The four tRNA genes are arranged as two tandem pairs with the first pair containing a proline tRNAAGQ gene and a leucine tRNAAAQ gene and the second pair containing another proline tRNAAGG gene and a threonine tRNAuQU gene. The two pairs are separated about 3 kb from each other, and the leucine tRNAAAG gene is of opposite polarity from the other three tRNA genes. The tRNA transcription units were sequenced by a unidirectional deletion dideoxyribonucleotide chain-termination method in the M13mpl8 and 19 vectors. The coding regions of the four tRNA genes contain characteristic internal split promoter sequences and do not encode intervening sequences nor the CCA trinucleotide found in mature tRNAs. The proline t R N A A G G gene is separated from the leucine t R …

The effect of constituent division of reading texts on ESL students was examined to note possible benefits to reading comprehension. An experimental group in each of three ESL proficiency levels was tested on a reading passage divided at the ends of lines at major constituent boundaries. Within each level, the experimental group was compared to a control group in three areas: reading time, test time, and test results. Results of the study do not support the theory that constituent division of reading texts could be beneficial to ESL students. The differences in reading time, test time, and test results of the experimental group and the control group in each level were insignificant.

The purpose of this thesis is to examine the coexistence of time in Gabriel Garcfa Marquez's One Hundred Years of Solitude as a cause of the supernatural events, the hereditary memory, and the solitude and to examine the effects of this mythical time frame on character development, plot, narrative structure, and theme. The thesis is divided into five chapters. The first chapter introduces the parchments as creators of mythical time. The second, third, and fourth chapters investigate the effects of this unconventional time. Supernatural events, clairvoyance, and solitude are all examined as effects. The final chapter correlates the writing of the parchments with the writing of the novel and explains the effects of unconventional time on the reader. Thus, this thesis illustrates how the coexistence of time functions of two levels: the level of the parchments and the level of the novel.

This paper explores the major historical interpretations of Hannah Arendt and analyzes her philosophy of history. Chapter One includes an introduction and a brief survey of the life of Hannah Arendt. Chapters Two and Three examine The Origins of Totalitarianism. The discussion concludes that Arendt's loose use of terms and some of her evidence can be called into question. Nevertheless, her work contains original insights about modern European political history. Chapter Four, a discussion of Arendt's Eichmann in Jerusalem: A Report on the Banality of Evil, emphasizes her portrait of Adolph Eichmann as a shallow, Nazi bureaucrat. Although the work is flawed with inaccuracies, her portrait of Eichmann as a prototypical bureaucratic killer is thought provoking. Chapter Five, an analysis of Arendt's philosophy of history, concludes that Arendt understood the pitfalls of theories of historical causality.

The purpose of this study was to determine the effectiveness of a transitional first grade program. A comparison of reading and math achievement and school attitude was the focus of the study. The study utilized a pretest/posttest design. The group of regular first grade students who qualified for the transitional program but attended regular first grade was the control group. The group of transitional first grade students was the experimental group. The regular first grade students received formal instruction in all academic areas. The experimental group received no formal instruction. All students were pretested and posttested using the Iowa Test of Basic Skills and the Minnesota School Attitude Survey. Testing was administered to small groups of five or less by the researcher. Scoring was done also by the researcher. An analysis of covariance was used to determine if a significant difference existed between the groups. The analysis of covariance did not produce a significant F at the .05 level when applied to the Iowa Test of Basic Skills except for reading for boys in both groups. The numbers in each cell were low and no further comparisons were made. Due to a testing date that was approved late in the …

The purpose of the present study was to determine if psychological stress, defined as academic examination stress, would systematically produce changes in immune parameters (immunoglobulin concentration) and psychological functioning. It was hypothesized that as examination stress occurred there would be an effect on immunological function consistent with heightened psychological activity/stress. Subjects were 23 master's and doctoral students in psychology who volunteered for the research project. All subjects were administered a series of psychological tests to measure stress, personality factors, emotional states, and anxiety levels. All tests were administered and.blood samples drawn over a period of 15 months across two lowstress and two high-stress periods. Immunological tests included white blood cell (WBC) differential count and radial immunodiffusion (RID) for the determination of concentration of different immunoglobulin classes (IgA, IgG, IgM) in serum. Data were treated to a one-way analysis of variance (ANOVA) with repeated measures, t /test for correlated samples correlational matrix between variables across assessments and discriminant function analysis. Results showed (1) increased immunoglobulin levels during periods of stress; (2) immunoglobulin G most consistently related to stress and probably most indicative of the stressed condition and biological resistance to stress; (3) anxiety related to external events; (4) increase in anxiety …

A skill instruction technique based on cognitive behavioral principles was applied to thermal imagery to determine if it could enhance either subjective or physiological responsiveness. The effects of imagery instruction were compared with the effects of muscle relaxation on imagery vividness, thermal imagery involvement, and the finger temperature response. The subjects were 39 male and 29 female volunteers from a minimum security federal prison. The personality characteristic of absorption was used as a classification variable to control for individual differences. It was hypothesized that high absorption individuals would reveal higher levels of imagery vividness, involvement, and finger temperature change; that imagery skill instruction and muscle relaxation would be more effective than a control condition; and that the low absorption group would derive the greatest benefit from the imagery task instruction condition. None of the hypotheses was supported. Finger temperature increased over time during the experimental procedure but remained stable during thermal imagery. The results suggest that nonspecific relaxation effects may best account for finger temperature increases during thermal imagery. Results were discussed in relation to cognitive-behavioral theory and the characteristic of absorption.

The purposes of this study were to determine the role expectations of academic counselors in vocational education as perceived by home economics cooperative education teachers and academic counselors, to compare the extent of agreement between these two groups, and to determine if selected demographic variables caused significant differences in perceptions of role expectations. This study surveyed randomly selected counselors and teachers by means of a questionnaire designed to ascertain role perceptions and to collect demographic data. The Likert-type scale instrument consisted of 46 items that were categorized into six areas of counseling tasks. A total of 45 teachers and 158 counselors returned usable questionnaires.

Prior to the issuance of Financial Accounting Standards Board Statement No. 8 (SFAS No. 8), there was a marked inconsistency in the area of accounting for foreign currency translation. Though designed to make the diverse accounting practices of multinational corporations (MNCs) more compatible, SFAS No. 8 was the subject of a great deal of criticism, eventually leading to the issuance of Financial Accounting Standards Board Statement No. 52 (SFAS No. 52). SFAS No. 52 differs from SFAS No. 8 on objectives and method of translation, and on accounting treatments of translation adjustments. This dissertation provides an empirical examination of the security market reaction to the accounting policy change embodied in SFAS No. 52, and its impact on the volatility of reported earnings of MNCs. The effects of the issuance and early adoption of SFAS No. 52 on security return distributions were determined by both cross-sectional comparisons of cumulative average residuals (CAR) between MNCs and domestic firms and between early and late adopters, and by time-series tests on CAR of MNCs. Two volume analyses were performed to test the effects of SFAS No. 52 on security volume. The first analysis was adjusted to remove the effects of the marketwide factors on …

This study evaluated the school psychologist's perception of effective models of consultation based upon referral problem and parent, teacher, and student response to treatment. Analyses of covariance determined that (a) parents' receptivity and total number of teacher contacts significantly influenced the parents' response to treatment; (b) teacher receptivity and total number of parent contacts significantly affected teachers' response to treatment; (c) students' response to treatment was significantly affected by the model of teacher consultation and the average number of minutes spent with the school psychologists; and (d) students in a Mental Health consultation group responded significantly more favorably than s tudents in Behavioral or Collaborative consultation groups.

Nocturnal op. 70 is one of the most important large-scale works written for guitar in the twentieth century. Brief biographical data and some background information on Nocturnal show how it exemplifies Britten's compositional approach. The focus of the analysis is on three structural aspects: the rhythmic, the intervallic, and the aspect of underlying pitch patterns. The rhythmic analysis discusses the distortion of rhythmic patterns by the use of compression, expansion, elisions, syncopation, and rhythmic dissonance. The pitch set analysis discusses the intervallic character of the work, identifying and correlating set types as they form networks of relationship. The reductive analysis discusses the underlying connections of focal pitches in the linear material of Nocturnal. The conclusion then correlates the results of the preceding analyses, discussing the large-scale unfolding of the form in Nocturnal.

The objective of this study was to explore intramolecular ketene cycloadditions with the anticipated results of developing new synthetic methodology for the synthesis of polycyclic compounds difficult to obtain by other procedures. (o-Alkenylphenoxy)ketenes were initially selected for this study because these ketenes provided a favorable proximity for the intramolecular [2+2] cycloaddition reactions. The difunctional precursors, (o-alkenylphenoxy)- acetic acids, were readily prepared from o-alkenylphenols and ∝-halocarboxylic acids and were converted to the corresponding acid chlorides by reaction with oxalyl chloride. The acid chlorides were dehydrochlorinated to the corresponding (o-alkenylphenoxy)ketenes by treatment with triethylamine. The ketenes undergo a facile intramolecular [2+2] cycloaddition to give polycyclic eye 1obutanones. The (o-vinylphenoxy)ketenes are clearly more reactive than the (o-allylphenoxy)ketenes and provide much better yields of the cycloaddition products because of electronic effects in the transition state in the cycloaddition process. The intramolecular [2+2] cycloadditions of keteniminium salts were included in this study as a more electrophilic alternative to ketenes that will react with less nucleophilic carbon-carbon double bonds. However, the use of keteniminium salts instead of ketenes in Intramolecular cycloadditions does have some limitations. The synthesis of benzofurans via the intramolecular [2+2] cycloadditions of (o-acylphenoxy)ketenes was accomplished. The initially formed ß-lactone cycloaddition products spontaneously underwent …
