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.

The role of specific amino acid residues in β-ketoadipate succinyl-coenzyme A transferase II from Acinetobacter calcoaceticus was investigated. A 1412 base pair BamiHI-EcoRI fragment carrying the catIJ genes was amplified by polymerase chain reaction and inserted into pUCl9 to generate the plasmid pCATEl9. Escherichia coli DH5α (pCATEl9) carrying only the catlJ genes expressed 3-fold higher enzyme activity than the parent strain. Two mutants were constructed by site directed mutagenesis so that glutamate was replaced by a glutamine at positions Gln155 and Gln193 in the ß subunit of the primary amino acid sequence of the CoA transferase. Both mutants produced transferase that was catalytically active suggesting that Glu155 and Glu193 do not participate directly in catalysis.

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.

The conclusion of the First World War brought the resumption of a struggle of a different sort: a battle between government and labor. Throughout 1919, government and labor squared off in a struggle over hours, wages, and nationalization. The Russian Revolution introduced the danger of the bolshevik contagion into the struggle. The first to enter into this conflict with the government were the shop stewards of Belfast and Glasgow. The struggle continued with the continued threats of the Triple Alliance and the police to destroy the power of the government through industrial action. This thesis examines the British labor movement during this revolutionary year in Europe, as well as the government's response to this new danger.

The study examined the effects of positive verbal reinforcement on intrinsic motivation by determining differential effects over four multidimensions of Ryan's Intrinsic Motivation Inventory (IMI). Subjects (N=60) were 30 male and 30 female college students. The subjects were blocked by gender and randomly assigned to a positive verbal reinforcement group or a control group. The subjects received 10 trials on the stabilometer. The results of the study indicated that there were significant group differences for composite intrinsic motivation and for perceived competence; however, there were no significant gender differences found. Furthermore, no group differences were reported for the underlying factors of interest/enjoyment, effort, or pressure/tension.

The degree of transfer of technical training to workplace behavior was evaluated using a Solomon Four-Group experimental design. Additionally, all groups received retrospective pretests. Subjects were 103 technicians in an electronics company. Supervisors rated technicians on behaviorally anchored rating scales which were developed and labeled as behavior description scales for simplicity. Analysis of variance revealed no effect for training nor pretest. A training-pretest interaction effect was revealed for one dimension (Communication with Support Groups). Analysis of covariance revealed main effects for pretesting for two dimensions (Problem Solving and Communication with Supervisor) and a pretest-training interaction-for one dimension (Problem Solving). Except for one dimension, t tests revealed no significant differences between traditional pretests and retrospective pretests, thus negating a hypothesized response shift bias.

This descriptive study utilized semi-structured interviews and observations to examine the experiences of hospitalized school-age children, and explore the potential of a live, closed-circuit television program as a psychosocial intervention. Among findings, Phase I data from 16 subjects indicates a) concern with painful medical procedures, particularly intraveneous (IV) injections, b) a desire for more information, especially concerning medical equipment, c) a variety of responses to social issues among subjects, d) the importance of activities, and e) the central role of the hospital playroom. Phase II data indicates that live, closed-circuit television can provide ambulatory and room-bound children opportunities for making choices, social interaction, participation, and information on their environment. Conclusions and implications are included.

This study proposes a model for the deconstruction of nationalism. Nationalism is a discursive construct. This construct manifests in ideologies and formalizes order. Individuals should question these institutions in order to achieve legitimate societal participation. This criticism can be accomplished through self-reflection. The model demonstrates that sanctioned individual(s) provide interpretations of events. These interpretations recycle authority. The hermeneutic obscures an individual's understanding of the originating fact. Self-reflection allows an individual, such as Malcolm X in the Nation of Islam, to come closer to discovering the original fact. Critiquing the hermeneutic can reveal the imperfections of the message(s). Revealing the imperfections of an ideology is the first step to the liberation of the individual and society.

The present investigation assessed Health Belief Model (HBM) variables and a measure of physical activity for both younger and older adults. Results of discriminant analyses suggest HBM variables and physical activity can predict age-group membership with 89% accuracy. The younger sample (n = 88; M= 21.5 years) was significantly more anxious about aging, perceived more barriers to exercise, less control from powerful others, and more social support than the older sample (n = 56; M = 71.8 years). For the younger sample, those who perceived more benefits of exercise, had social support, were male, and were less anxious about aging were more active. For the older sample, those who perceived more benefits of exercise were more likely to be active.

This study analyzes effective service delivery in organizations serving the mentally retarded. Qualitative organizational analyses of three community care facilities were compared to assess effectiveness. Data were gathered by systematic observations, field notes, documents, and employee interviews. Program analysis, the funding system of service delivery, and staff attitudes best indicated effective service. I concluded that effectiveness would improve by focusing on individual consumer needs and further defining service delivery.
