This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for …

The purpose of this study was to: (1) identify the sources of job-related stress which create excessive pressures for the directors and faculty of medical record administration and medical record technology programs; (2) identify the strategies that the directors and faculty of medical record administration and medical record technology programs find most helpful in coping with stress; (3) determine the relationship among demographic variables and job-related stressors as perceived by the directors and faculty of medical record administration and medical record technology programs; and (4) determine the difference among the means of five stress factors as perceived by the directors of medical record administration, faculty of medical record administration, directors of medical record technology and faculty of medical record technology programs. Questionnaires were mailed to 403 respondents. The response rate was 81.3%. Within the limitations of this study, the results revealed that "Having insufficient time to keep abreast of current developments in my field"was the highest stressor. The top stress coping strategy was "Social interaction." The relationship between demographic variables and five stress factors of reward and recognition, time constraint, departmental influence, professional identity and student interaction revealed a positive correlation between degree and professional identity factor, and a negative …

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.

Initial velocity studies of O-acetylserine sulfhydrylase-B (OASS-B) from Salmonella typhimurium using both natural and alternative substrates suggest a Bi Bi ping pong kinetic mechanism with double substrate competitive inhibition. The ping pong mechanism is corroborated by a qualitative and quantitative analysis of product and dead-end inhibition. Product inhibition by acetate is S-parabolic noncompetitive, indication of a combination of acetate with E followed by OAS. These data suggest some randomness to the OASS-B kinetic mechanism. The pH dependence of kinetic parameters was determined in order to obtain information on the acid-base chemical mechanism for the OASS-B reaction. A mechanism is proposed in which an enzyme general base accepts a proton from α-amine of O-acetylserine, while a second enzyme general base acts by polarizing the acetyl carbonyl assisting in the β-elimination of the acetyl group of O-acetylserine. The ε-amine of the active site lysine acts as a general base to abstract the α-proton in the β-elimination of acetate. At the end of the first half reaction the ε-amine of the active site lysine that formed the internal Schiff base and the general base are protonated. The resulting α-aminoacrylate intermediate undergoes a Michael addition with HS‾ and the active site lysine donates its …

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.

The increase in the number of nontraditional aged undergraduate students (25 yrs. and older) and students transferring between post-secondary institutions has raised the question of whether effective instruction is viewed the same by these different groups of students. This study addressed this question by analyzing the responses of these different groups to 23 instructional questions on a standard faculty evaluation form.

This study emphasizes the impact of family planning program components on contraceptive prevalence in less industrialized countries. Building on Lapham and Mauldin's "Program Effort and Fertility Decline" framework and policy evaluation's theory, the author developed two models to examine the impact of family planning programs on contraceptive prevalence and fertility under the constraints of socioeconomic development and demand for family planning. The study employed path analysis and multiple regression on data from the 1982 program effort study in 94 less developed countries (LDCs) by Lapham and Mauldin and 98 LDCs of the 1989 program effort study by Mauldin and Ross. The results of data analyses for all data sets are consistent for the most part. Major findings are as follows: (1) A combination of program effort and socioeconomic development best explains the variation of contraceptive prevalence. (2) Among socioeconomic variables, female literacy exerts the strongest direct and indirect influences to increase contraceptive prevalence and indirect influence to decrease total fertility rate. (3) Christianity performs a significant role in reducing contraceptive prevalence. (4) Among program effort components, availability and accessibility for fertility-control supplies and services have the most influence on contraceptive prevalence. (5) When controlling for demand for family planning, female …

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 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.

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.

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.

In the last twelve years there has been considerable research interest in mathematical programming approaches to the statistical classification problem, primarily because they are not based on the assumptions of the parametric methods (Fisher's linear discriminant function, Smith's quadratic discriminant function) for optimality. This dissertation focuses on the development of mathematical programming models for the three-group classification problem and examines the computational efficiency and classificatory performance of proposed and existing models. The classificatory performance of these models is compared with that of Fisher's linear discriminant function and Smith's quadratic discriminant function. Additionally, this dissertation investigates theoretical characteristics of mathematical programming models for the classification problem with three or more groups. A computationally efficient model for the three-group classification problem is developed. This model minimizes directly the number of misclassifications in the training sample. Furthermore, the classificatory performance of the proposed model is enhanced by the introduction of a two-phase algorithm. The same algorithm can be used to improve the classificatory performance of any interval-based mathematical programming model for the classification problem with three or more groups. A modification to improve the computational efficiency of an existing model is also proposed. In addition, a multiple-group extension of a mathematical programming model …

Government investigations into the motion picture industry are well-documented, as is the widespread blacklisting that was concurrent. Not nearly so well documented are the many investigations of musicians and musical organizations which occurred during this same period. The degree to which various musicians and musical organizations were investigated varied considerably. Some warranted only passing mention, while others were rigorously questioned in formal Congressional hearings. Hanns Eisler was deported as a result of the House Committee on Un-American Activities' (HUAC) investigation into his background and activities in the United States. Leonard Bernstein, Marc Blitzstein, and Aaron Copland are but a few of the prominent composers investigated by the government for their involvement in leftist organizations. The Symphony of the Air was denied visas for a Near East tour after several orchestra members were implicated as Communists. Members of musicians' unions in New York and Los Angeles were called before HUAC hearings because of alleged infiltration by Communists into their ranks. The Metropolitan Music School of New York, led by its president-emeritus, the composer Wallingford Riegger, was the subject of a two day congressional hearing in New York City. There is no way to measure either quantitatively or qualitatively the effect of …

This study used a posttest only design to determine the effects of a strategic thinking program on the Cognitive Abilities Test (CogAT, Form 4) scores of seventh graders who received direct instruction in Strategic Thinking Skills (STS) with the scores of seventh graders who did not receive direct instruction in STS. The study was conducted in a large suburban middle school in north Texas.

Hawthorne's metafiction, fabulation, and hermeneutical semiotics are investigated in the tales and in all the novels in chronological order, including his unfinished works.

Whereas scholarly malcontents and naifs in late Renaissance drama represent the actual notion of university graduates during the time period, scholarly tricksters have an obscure social origin. Moreover, their lack of motive in participating in the plays' events, their ambivalent value structures, and their conflicting dramatic roles as tricksters, reformers, justices, and heroes pose a serious diffculty to literary critics who attempt to define them. By examining the Western dramatic tradition, this study first proposes that the scholarly tricksters have their origins in both the Vice in early Tudor plays and the witty slave in classical comedy. By incorporating historical, cultural, anthropological, and psychological studies, this essay also demonstrates that the scholarly tricksters are each a Jacobean version of the archetypal trickster, who is usually associated with solitary habits, motiveless intrusion, and a double function as selfish buffoon and cultural hero. Finally, this study shows that their ambivalent value structures reflect the nature of rhetorical training in Renaissance schools.

The postwar transformation of the international environment has caused economic issues to become a main source of contention among industrial states. The trade imbalance between Japan and its trading partners became a major source of conflict. Reciprocity of access and opening the market of Japan became the main point of debate and the major issue affecting relations between Japan and the United States. While the distinction between the domain of domestic and international politics increasingly is blurred, different domestic political economies create bilateral political and economic conflict. The structure and politics of intercorporate groups or vertical keiretsu are a major feature of Japan's industrial structure and political economy. This case study examines how vertical keiretsu in the automobile and home electric appliance industries affect the Japanese political economy and international trade. A political economy approach focuses on the political context of economic phenomena by analyzing both political and economic variables. Case studies of keiretsu were used in order to gain an understanding of Japan's political economy. A number of propositions or assumptions about the political economy and the dynamics of keiretsu were examined in these studies. It was found that vertical keiretsu influences the industrial sector, trade, and foreign policies …

The purpose of the present cross-sectional study was to examine the effects of ambiguity of loss and type of caregiver-to-patient relationship on anticipatory grief, negative physical and psychological outcomes associated with grief, and boundary ambiguity in family caregivers of chronically ill patients. Questionnaires were completed by 23 parents of ill children and 30 spouses of ill mates. Using an original and a revised concept for level of ambiguity, partial support was found for the prediction that parents and spouses in high ambiguity of loss circumstances would report more anticipatory grief than those in low ambiguity ones. Contrary to prediction, a slight but nonsignificant trend occurred for parents and spouses in low ambiguity situations to report more negative physical and psychological effects associated with grief as well. Level of ambiguity was not found to impact boundary ambiguity as had been hypothesized. Spouses reported more boundary ambiguity than parents, regardless of level of ambiguity of the loss. Contrary to prediction that parents would report less anticipatory grief and more negative physical and psychological outcomes than spouses, generally, no significant differences were found between the two groups. However, using the original concept of ambiguity, parents did tend to recall more past grief than …

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.

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 quantum dynamics of minimum uncertainty wave packets in a system described by the surface-state-electron (SSE) Hamiltonian are studied herein.

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

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.

In this study, the unique style of percussion writing in the chamber works of George Crumb, written between 1960 and 1980, is examined. The principal aspects examined within this study include: the extended instrumental techniques, the use of percussion within the musical imagery, soloistic treatment, compositional and notational procedures, and specific performance problems pertaining to the chamber work Songs, Drones, and Refrains of Death.
