Chronic ventricular sympathectomy elicits changes in the coronary circulation, myocardial oxygen consumption and size of infarction resulting fromcoronary occlusion. These changes indicate a change occurring in the basic metabolism of the heart in response to the removal of its sympathetic nervous input. This hypothesis was tested using two groups of dogs, a shamoperated control and a ventricular sympathectomized group. The sympathectomy procedure was an intrapericardial surgical technique which selectively removes ventricular sympathetic input. Four weeks after surgery, left ventricular tissue samples were obtained and rapidly frozen to -80°C. Selected metabolic variables were then compared between the two groups.

The problem with which this study is concerned is comparative administrative leadership behavior between municipal and university administrators. The specially designed survey instrument elicited respondents' perceptions of their administrative leadership behavior based on the 12 dimensions of the Leader Behavior Description Questionnaire- XII.

Four aspects of the dynamics of continuous-time dynamical systems are studied in this work. The relationship between the Lyapunov exponents of the original system and the Lyapunov exponents of induced Poincare maps is examined. The behavior of these Poincare maps as discriminators of chaos from noise is explored, and the possible Poissonian statistics generated at rarely visited surfaces are studied.

The overall purpose of this study was to identify the major factors and events that led to the establishment of the Federal Universities of Technology in Nigeria. The study examined and analyzed the growth and development of the three Nigerian Federal Universities of Technology at Owerri, Akure, and Minna.

Learning styles and readiness for self-directed learning were identified for 125 adult employees enrolled in self-paced training courses. The success of the self-paced instruction was measured by confidence to perform learned skills on the job. Confidence scores were compared across learning style types and self-directed learning readiness. It was concluded that self-paced training programs can be effective for a variety of learning style preferences. Additionally, adult employees who are highly self-directed will experience greater success in self-paced instruction than those less self-directed. The implication for businesses and academic institutions seeking to employ technology based, self-instructional programs is that a return on investment can be maximized by an examination of the target audience. Training programs which are self-paced may not generate the desired success which will translate into effective job performance for those adults who are not ready for self-directed learning.

The first objective of this research was to identify whether Asian-Americans having higher than average levels of income and education represent an appropriate target market for four food product categories. Second, the impact of national origin membership, demographic variables, and level of acculturation on food consumption was determined. In addition, perceptions related to sensory and nutritional factors and the cultural acceptability of the products were identified and interpreted to determine if the variables differed among specific groups of Asian-American consumers.

This study was designed to determine the effectiveness of filial therapy as a method of intervention for single parents and their children.

The simplicity and ease of use of the Rasch procedure is a decided advantage. The test user needs only two numbers: the frequency of persons who answered each item correctly and the Rasch-calibrated item difficulty, usually a part of an existing item bank. Norms can be computed quickly for any specific group of interest. In addition, once the selected items from the calibrated bank are normed, any test, built from the item bank, is automatically norm-referenced. Thus, it was concluded that the Rasch quick norm procedure is a meaningful alternative to traditional classical true score norming for test users who desire normative data.

The present study used the Psychoanalytic Rorschach Profile (PRP) to assess differences in personality organization in violent and nonviolent juvenile offenders.

The regulation of short chain fatty acid metabolism has been examined. Metabolism of acetoacetate, and short chain fatty acids such as butyrate and valerate, is predicated upon the expression of genes of the ato operon. Acetoacetate induces expression of a CoA transferase (encoded by the atoDA genes) and expression of a thiolase (encoded by the atoB gene). Metabolism of saturated short chain fatty acids requires the activities of the transferase and thiolase and enzymes of 6-oxidation as well. Spontaneous mutant strains were isolated that were either constitutive or that were inducible by valerate or butyrate instead of acetoacetate.

The purpose of this study was to determine the accuracy of advertised reports by computer software companies claiming to improve critical thinking skills.

The purpose of this study was to survey Algebra II teachers in the State of Texas to determine the extent to which they use technology for the delivery of instruction. Additionally, the study attempted to determine reasons why teachers do or do not use technology when they have a choice.

Prolonged exposure to microgravity is known to invoke physiological changes which predispose individuals to orthostatic intolerance upon readaptation to the earth's gravitational field. Attenuated baroreflex responsiveness has been implicated in contributing to this inability to withstand orthostatic stress. To test this hypothesis, eight individuals were exposed to 15 days of simulated microgravity exposure using the 6° head-down bed rest model. Prior to, and after the simulated microgravity exposure, the following were assessed: a) aortic baroreflex function; b) carotid baroreflex function; c) cardiopulmonary baroreflex function; and d) the degree of interaction between the cardiopulmonary and carotid baroreflexes.

The primary purpose of this study was to find the content and form of movies which conform to the taste of the majority of Thai audiences and, at the same time, are universal enough to attract international audiences. Because film is an extension of other art forms, this required extensive research into the roots of Thai performing arts.

Numerous investigations with college students have found that mild depressives perceive environmental contingencies more accurately than do nondepressives. The present study explores this 'depressive realism' phenomenon in a hospitalized sample.

The purposes of this study were (a) to examine whether social support decreases as the person with HIV disease progresses from asymptomatic HIV to symptomatic AIDS and (b) to examine the extent to which general well-being might be mediated through a religious and/or spiritual support system.

This study examined international education (IE) programs in Texas community colleges to determine how they compare to a general, theoretical model of IE programs discussed in the literature. The study proposed: (a) to describe, through a review of literature, the components of IE; (b) to describe the administration of IE within the Texas community colleges; (c) to identify existing IE instructional activities; (d) to describe the student support services related to IE which are in practice; (e) to describe what community and out of country outreach components are in operation; and (f) to determine how the IE programs in Texas community colleges compare to theoretical components of IE programs as identified in the literature.

This study describes the language behaviors and social strategies of English as Second Language (ESL) and English as Primary Language (EPL) pre-kindergarten students during cooperative Computer Assisted Instruction (CAI) experiences. Thirty-three pre-kindergarten subjects ages four to five years, were videotaped at two personal computers during self-selected center time. The sources of data for this descriptive study were a parent computer survey, videotapes, a subject interview derived from the Young Children's Computer Inventory, and written records.

The application of Gowin's knowledge vee as a means to design instruction for adult Bible study was investigated in this study. The study was designed to determine whether subjects using this instructional approach differed from subjects using traditional instructional materials regarding their attitudes toward Bible study, attendance, knowledge retention, application of study materials to life, and recruitment of new class members.

A primary purpose of the study was to articulate the significance of these compositions to the twentieth century repertoire, with special attention given to Dies Natalis, recognized as an outstanding contribution to English music literature. Overviews and specific analyses, with pertinent performance applications and background data, fulfill this purpose and provide information of merit for the programming and performance of Finzi's songs for high male voice.

There is a limited amount of research dealing with the wealth effects of sale-and-leaseback transactions, but previous research has focused predominantly on the tax effects of these transactions. The results of these studies have often been in conflict with one another. This dissertation shows that tax effects do play a role in determining the wealth effect of sale-and-leasebacks on stockholders, but there exists a framework of finance research that suggests several other factors could play a determining role as well.

The purpose of this study was to try to identify the impact of ambiguity and risk on the auditor's judgment about inherent risk and control risk when planning the audit. A second purpose was to determine how ambiguity tolerance/intolerance affects judgment.

The purpose of this study was to ascertain the image of the University of North Texas as perceived by the University Administration and Board of Regents, Texas Higher Education Coordinating Baord and selected Legislators, and the Boards of Directors of the Metroplex area Chambers of Commerce. The significance of the study was to contribute knowledge that could be used to construct a more direct and cost effective marketing plan.

In "Discourse in the Novel," Mikhail Bakhtin tells us that "Every discourse presupposes a special conception of the listener, of his apperceptive background and the degree of his responsiveness." My study of Wallace Stevens's poetry examines Stevens's "conception of the listener"—in the form of his intratextual readers, their responsiveness, and the shapes that responsiveness takes—and attempts to formulate out of that examination Stevens's theory of reading embodied in his canon of poems.
