This study identified and compared characteristics in the career progression of African-American college presidents of institutions in the continental United States. The study was concerned with personal, educational and professional characteristics of these senior level administrators. From a population of 141 individuals, 73 presidents participated in this study. Frequencies, means, percentages, chi-square, crosstabulations and analysis of variance (ANOVA) were employed in the analysis of data. The level of significance was set at 0.05.

Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.

This study examines the association between the attitudes of students toward computers and their knowledge of the ethical uses of computers. The focus for this research was undergraduate students in the Colleges of Arts and Sciences (Department of Computer Science), Business and Education at the University of North Texas in Denton, Texas.

The problem addressed in this study was to determine if a significant association exists between attributions and academic achievement among students in a program of religious training at a Bible college. The research was designed to ascertain if optimistic attributions are more frequently associated with students in programs of religious education than with students in a public state-supported university environment. No significant correlation was found between optimistic explanatory styles and the academic achievement of Bible college students. A significant positive difference was found to exist between the explanatory styles of students at The Criswell College and students at the University of North Texas. Students in religious courses of study tended toward attributions for negative events that were external, unstable, and specific. The University of North Texas students tended toward attributions for negative events that were internal, stable, and global.

The factors involved in calculating Standard Visual Range (SVR) are discussed, and a comparison is made between the visibility reported by airport observers and the photographic slide/ optical densitometer method of calculating SVR. Using slides of Houston, Texas, from the fall and winter of 1988-89, it was found that the altitude at which the contrast measurements are made significantly affects the SVR. Also an index for predicting high and low humidity was developed using the blue/red ratio of the log exposure of the sky, and sun/shade target condition.

This study explored the attitudes and perceptions of faculty members in Rajamangala Institute of Technology (RIT), Thailand. The purpose of this study was to (a) determine which demographic variables are associated with faculty members attitudes toward the implementation of computers in higher education in Thailand, and (b) determine perceptions among faculty members toward barriers to the widespread use of computers.

The research was designed to test the hypothesis that significant differences exist between Hispanic and non-Hispanic students respecting background characteristics and reasons for enrollment in selected two-year colleges. The findings led to firm conclusions regarding the need for educational institutions to provide remedial and tutorial services, liberal financial aid, culturally sensitive institutional ambience, diversity in faculty, counselors, and staff, and instructional and student development programs responsive to the cultural diversity of all students.

Written in the tradition of American political suspense thrillers such as "Fail-Safe" and "Seven Days In May," "Bearclaw" uses their idealistic and nationalistic elements to tell a story of an American President eager to lead the world's peoples in a quest to achieve man's "highest destiny," the conquest of space. Believing that this common goal will cause mankind to come together in a spirit of brotherhood, he misreads the historical purpose of the United States and, in the end, refuses to recognize the obvious truths of human frailty and ambition even though he has been victimized by them. The Introduction is a brief survey of the sociopolitical and literary forces which combined to create the American political suspense thriller and an attempt to define its place in the literary canon.

Cardiovascular responses and tolerance to an orthostatic stress were examined in eight men before and after eight months of endurance exercise training. Following training, maximal oxygen consumption and blood volume were increased, and resting heart rate reduced. Orthostatic tolerance was reduced following training in all eight subjects. It was concluded that prolonged endurance training decreased orthostatic tolerance and this decrease in tolerance appeared associated with attenuated baroreflex sensitivity and alterations in autonomic balance secondary to an increased parasympathetic tone noted with training.

The purpose of this study was to investigate the interpersonal influences which Bohumil Makovsky, Director of Bands and Chairman of the Music Department at Oklahoma A&M College from 1915 to 1943, had on his students and peers, as confirmed through the perceptions of selected individuals, and to determine what personal characteristics and means he drew upon to induce changes in his students and peers.

This thesis examines the trends in historical interpretation concerning the coming of the American Civil War. The main body of works examined were written between 1950 and 1976, beginning with Allan Nevins' Ordeal of the Union and concluding with David M. Potter's The Impending Crisis, 1848-1861. It also includes a brief survey of some works written after 1976. The main source for discovering the materials included were the bibliographies of both monographs and general histories published during and after the period 1950-1976. Also, perusal of the contents and book review sections of scholarly journals, in particular the Journal of Southern History and Civil War History, was helpful in discovering sources and placing works in a time chronology for the thesis narrative.

Observed and expected heterozygosity (H) levels for ten electrophoretic blood marker loci and expected H for seven red blood cell (RBC) anitgen/antibody loci were examined for 20 years in American Standardbred and 30 years in American Saddlebred horses. Standardbreds were classed by gait, Trotter and Pacer, and evaluated separately in most analyses. 4,404 Trotters and 12,271 Pacers were found to have statistically highly significant losses of mean total observed H through time for the ten electrophoretic loci (P<0.005), although in Trotters the loss was more extreme (P<<0.001). Loss of H in 5984 Saddlebreds was not significant (P=0.259). Correlations of RBC expected H through time showed decreases in all three groups.

This research addresses the question of whether there are personal characteristics of purchasing managers that lead them to make decisions regarding buyer-seller partnerships, and supplier sourcing in particular, that may be suboptimal, therefore affecting the performance of the firm. This question warrants study due to the current business environment, in which business firms have been entering into both formal and informal buyer-seller partnerships as a means of surviving in a highly competitive environment.

This thesis deals with the role of property in the formation of the American Constitution and government. Charles Beard's views on property are compared with writings from the eighteenth century. Beard's writings on property and his critics are examined in the first two chapters. Then, the thesis's two historical contexts are evaluated. Concentrating on the Enclosure Acts, the fourth chapter looks at the importance of land to the former Englishmen. The eighteenth century view of property is the focus of the fifth section. The last chapter contrasts the two different views of property. Beard believed that the Constitution was a conservative document that protected the property of the few over the many. The Founding Fathers actually included liberal protections for property in the eighteenth century.

The primary purpose of this study was to determine if there is a relationship between the bibliographic citation practices of the members of a discipline and the emphasis placed on citation accuracy and purposes in the graduate instruction of the discipline.

The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning.

The purposes of this study were to compare the childrearing attitudes of church-related Korean American immigrant parents and Korean parents as measured by the Parent As A Teacher Inventory (PAAT), and to identify relationships between the PAAT childrearing subsets and demographic variables including sex of child, sex of parent, education of parent, family income level, maternal employment, accessibility to the child, language of parent, and length of residence in America.

Cognitive ratings that use bipolar constructs based upon similarity and contrast have been shown to be biased towards the similarity pole in approximately a 62/38 ratio. This bias has also been known to shift in the contrastive direction for individuals who have psychiatric problems. This quantitative measure of cognitive change has a potential for characterizing cognitive changes that occur during the disease process, including recovery from disease. The present study investigated changes in self-aspect ratings and bipolar construct use in adult male veterans who had undergone coronary artery bypass graft surgery. Results indicated that treatment subjects' self-aspect and construct ratings were more negative than controls'. Results also indicated that all subjects rated core interpersonal self-aspects closest to the expected bias, while self-aspects related to cardiac recovery problems were rated in the most contrastive direction. The results finally suggested that the greatest degree of change for the treatment subjects were in emotionally generated constructs. The results suggested a preliminary validation for characterizing cognitive changes in the disease process by measuring shifts in bipolar construct ratings.

Rhizobia are Gram-negative, rod-shaped, soil bacteria with the ability to fix atmospheric nitrogen into ammonia as symbiont bacteroids within nodules of leguminous plant roots. Here, resident Rhizobium plasmids were studied as possible sources of components for the construction of a cloning vector for Rhizobium species.

Male and female college students were administered scales assessing their daily hassles, negative life events, control, commitment, challenge, psychological symptomatology, psychological distress, and physical symptomatology. Stepwise multiple regression analyses showed that control, commitment, and challenge act in an additive (rather than multiplicative) manner in relation to psychological and physical outcome measures.

The major purpose of this study was to determine if pre-clinical medical school course examinations reflect critical thinking skills. The entire second year class from a medical school in the southwest made up the population. Student examination results from the first two years as well as scores on the Watson-Glaser Critical Thinking Appraisal were used in this study.

This thesis discusses Mexican immigration into Texas, and the communities in which the immigrants settled. The focus is on Dallas, with particular emphasis placed upon the women of Little Mexico, a specific barrio there. Sources include interviews with the subjects and their descendants, newspaper articles, journals, unpublished theses about Little Mexico, and books.

This study identified and defined leader behaviors with two levels of leadership in a self-managed team organization. Job analysis methodology was used. A comparison of task importance values was made within groups and between hierarchical levels in the organization. Identified leader behaviors were compared with effective, traditional leader performance. Qualitative data collected throughout the investigation clarified an integrative model for effective organizations developed from the literature. The model included leader characteristics and team member behaviors when using self-managed teams.
