Thermal depletion of a geothermal reservoir with both fracture and pore permeability
A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use is justified by comparing the results with solutions of the exact equations. The equations for the temperature decline can be solved quickly. In the model, fractures are characterized by three parameters: aperture w, permeability k/sub fr/, and spacings between fractures D. For certain values of these parameters, cool reinjected fluid in fractures may reach the production wells long before all the warm pore fluid has been tapped, shortening the useful lifetime of the field. The traditional (and important) problems of reservoir engineering, flow rate determination, drawdown, sweep patterns, etc. were ignored. Thus the results are most useful in providing a correction factor which can be applied to lifetime estimates obtained from a detailed simulation of a field assuming porous rock. That correction factor is plotted …

Analysis of a Cylindrical Shell Vibrating in a Cylindrical Fluid Region
Analytical and experimental methods are presented for evaluating the vibration characteristics of cylindrical shells such as the thermal liner of the Fast Flux Test Facility (FFTF) reactor vessel. The NASTRAN computer program is used to calculate the natural frequencies, mode shapes, and response to a harmonic loading of a thin, circular cylindrical shell situated inside a fluid-filled rigid circular cylinder. Solutions in a vacuum are verified with an exact solution method and the SAP IV computer code. Comparisons between analysis and experiment are made, and the accuracy and utility of the fluid-solid interaction package of NASTRAN is assessed.

Feedback as a means of decreasing residential energy consumption. Report PU/CES 34
When residential units are analyzed in human factor terms, it is apparent that the consumption level feedback (typically a bill, calculated once a month, over all appliances) is inadequate to give the resident useful information about his energy consuming actions. The present study tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electric usage would be effective in reducing electric consumption. In the studied homes, central air-conditioning is the largest single source of electric power consumption during the summer. Accordingly, it was possible to predict the household's expected electric consumption in terms of the average daily outdoor temperature. Predicted electric consumption was derived from a previous month's modeling period during which a regression line was fitted to predict consumption from average daily temperature, for each home. Feedback was expressed as a percentage of actual consumption over predicted consumption. Feedback was displayed to homeowners four times a week for approximately one month. The results confirmed the prediction. Before feedback began, the feedback and control groups were consuming electricity at approximately equal rates. During the feedback period, the feedback group used 10.5 percent less electricity. The effectiveness of the feedback procedure was explained in terms of its …

The Impact of Role Playing on Selected Values Claims Held by Third- and Fifth-Grade Students
The problem with which this investigation was concerned was that of determining whether role playing could be used successfully to help elementary school children clarify selected values claims. The changes in children's values claims were measured by using the Semantic Differential developed by Osgood and others. This study had a threefold purpose. The first was to determine if children's values claims in the third grade could be changed by a concentrated program of role playing. The second was to determine whether children's values claims in the fifth grade could be changed by a concentrated program of role playing. The third was to determine if there was a difference in the amount of change in third- and fifth-grade children's values claims after both grades had experienced a concentrated program of role playing. The following conclusions were reached: (1) Role playing experiences can be used successfully to change third-grade children's values claims in respect to the concepts of honesty and consideration of others. (2) Whether role playing can be used successfully with third-grade children to change their values claims in regard to respect for property is open to question. (3) Whether role playing can be used successfully with fifth-grade children to change …

The Use of Concepts of Income Determination by Members of the Agricultural Sector of the Plains Area of Texas
The problem with which this study is concerned is that of determining income concepts employed by members of the agricultural sector to determine change in equity of the owner of an entity. A secondary purpose was an investigation of the factors which influenced the decision model selected to determine income. Major findings of the study indicated that financial data is used differently by members of the sector and the accountant. Respondents did not agree among themselves about the information that should be used in income measurement, nor were they consistent in use of a given concept. Finally, evidence was presented which indicated that changes in terms used to ask for change in equity leads to different responses.

An Evaluation of the Impact of Citizen Participation on the Goals for Dallas Program as Developed and Implemented by the City of Dallas, Texas
This study is designed to evaluate the impact of citizen participation in the Goals for Dallas program on the establishment and accomplishment of the goals. Also evaluated are the impact of community leaders on the program, the extent and degree of citizen participation, factors which encouraged and discouraged participation, the impact of local media, and the impact on citizen participants of participating. Twenty-five specific findings are presented, based on the compilation and analysis of inputs received from the citizens and community leaders. Among the most important of these are as follows. 1) The extent of participation on the part of those citizens who did participate in the program was significant. 2) Related to the total adult population of the city, the extent of total citizen participation was small. 3) The program as designed and implemented did have a substantial impact in assisting to overcome citizen apathy in the city. 4) The key items which tended to encourage citizen participation were publicity, civic duty, neighborhood meetings, and personal rewards. 5) The general factors which discouraged citizen participation were general suspicion of the program, general apathy, lack of publicity, and a general suspicion of government. 6) Citizen participation had a significant impact …

A Study of Community Education in the State of Texas
The problem of this study was to determine the effectiveness of community education in Texas as perceived by the superintendents, community education directors, and selected laymen in the participating school districts. The sources of data included a review of the literature and supplemental materials. The survey technique, employing a jury—validated questionnaire, was used to collect the perceptions of superintendents, principals, teachers, and college professors in the State of Texas. A total of 121 educators and lay participants responded to the questionnaire. As a result of the study, it appears that according to the perception of those surveyed, that the community education programs in Texas are accomplishing at least 83 percent of all the goals purported in the nationally-circulated literature. Based on the study, it appears that the ongoing community education programs in Texas are perceived to be effective by those most closely associated with them and therefore deserve to continue to receive special considerations and funding.

Affecting Children's Value Claims by Using High-Level Questioning Focused on Selected Poetry
This study was to determine the extent to which the use of high-level questioning, through eliciting responses to selected poems, affects children's value claims. Twenty-seven seventh-grade boys comprised the control group, and twenty-seven eighth-grade boys comprised the experimental group. The experimental group took part in values-clarification experiences for sixteen weeks. The control group received no value instruction. The Values Inventory was administered to both groups at the beginning and at the end of the sixteen weeks. Testing of the hypotheses resulted in eight of the hypotheses being significant at the .01 level, indicating that values-clarification experiences using high-level questioning and selected poems did affect children's value claims.

The Effect of Touch on Interpersonal Attraction of Selected Patients in an Initial Interview Held in a Neuropsychiatric Setting
This study was designed to determine the effect of touch on the interpersonal attraction between therapist and patient. Four instruments were used to measure the effect, those measurements included "Client's Personal Reaction Questionnaire," "Attitudes Toward Psychotherapy and Psychotherapists Scale," actual physical distance and actual timed verbal measure. The general nature of the research hypotheses stated that the touch technique would increase the interpersonal attraction of the patients toward the therapist as indicated by the four measures. The results of the study led to the conclusion that touch during a single interview session effects statistically significant change in interpersonal attraction when measured by actual physical distance. However change in interpersonal attraction was not found when measured by the "Client's Personal Reaction Questionnaire," "Attitudes Toward Psychotherapy and Psychotherapists Scale" and an actual timed verbal measure. Implications of the study, based on observations of the experimenter, were that touch is successful in helping hospitalized neuropsychiatric patients increase their interpersonal attraction and that this attraction cannot always be measured by global questionnaires and specific amounts of verbalization. A similar study should be replicated with subjects other than neuropsychiatric patients, such as hospitalized medical patients, college students and children.

The Understanding and Attitudes of Elementary Teachers Toward Economic Education
The purposes of this study are to determine the understanding of economic concepts and attitudes toward economic education of selected elementary teachers, to determine which variables relate to the understanding of economic concepts and attitudes toward economic education, to determine the interaction of selected variables, and to determine if there is a positive correlation between the understanding of economic concepts and attitudes toward economic education. The analysis of data reveals the following: 1. Completion of a recent college level social studies methods course does not appear to have a significant relation to the teachers' understanding of economic concepts. The methods course does appear to have some positive significant relation to teachers' attitudes toward economic education, although not significant at the .05 level. 2. Completion of two or more college level courses in economics does not appear to have a significant relation to the teachers' understanding of economic concepts or their attitudes toward economic education. 3. Participation in a Developmental Economic Education Program (DEEP) workshop appears to have a significant relation to the teachers' understanding of economic concepts, but does not appear to have a significant relation to their attitudes toward economic education. 4. Teaching assignment (classroom organization) does not appear …

A Study of Administrator Perceptions of the Effectiveness of Practices to Facilitate the Desegregation Process of Selected School Districts
It has been just over twenty years since the Brown v. Board of Education of Topeka, Kansas decision was handed down by the Supreme Court. During this period, educators, and in particular, school administrators have found themselves in a unique position between two masters—the public that supports public education through taxes, and the orders of the courts they are legally required to follow. Therefore, school administrators, functioning as social engineers, have devised various practices to provide a smooth transition from segregated to desegregated school systems. This study was designed to determine the practices used by selected school districts to cope with this change and to determine the effectiveness of these practices as perceived by central-staff administrators. Selected large city school districts with enrollments of 30,000 students and above, located in the six southern states under the jurisdiction of the Fifth Circuit Court of Appeals, were selected for this study. These districts, of which there were thirty-four, also had to be under a federal court desegregation order to be included. The survey data reveal that the most effective desegregation practice for students is the provision of alternative schools and programs to assist students unable to cope with the regular school environment. …

Assessing and Influencing the Attitude and Knowledge of Selected Post-Secondary Students Concerning Body Language
This investigation, which was conducted on the post-secondary level and included vocational and academic students, was undertaken to develop an instrument to assess the attitude and knowledge of students concerning body language and to develop a module of instruction in body language to favorably influence their attitude and knowledge concerning body language. Hypotheses were formulated related to the differences in mean effective and cognitive scores of the experimental group who were taught body language and the control group. Additional hypotheses were formulated related to mean differences in the scores of students differing in age, sex, business experience, and prior exposure to body language. The findings of this study included first, the testing of the instrument; second, the testing of the validity of the research design and third, the testing of the hypotheses. The following conclusions are based on the findings of the study: the instrument seems to be acceptable for assessing the attitude and knowledge of post—secondary students concerning body language, the module of instruction in body language seems to be acceptable as a basis for influencing the attitude and knowledge of post—secondary students concerning body language, the mid-management and speech students were comparable in attitude and knowledge concerning body …

An Analysis of the Effects of a Human Relations Component in an Introduction to Education Course on the Self Concept and Interpersonal Relations of Secondary Education Pre-Service Teachers
The problem of this study was to analyze the effects of a human relations component in an introduction to education course on the self-concept and interpersonal relations of secondary education pre-service teachers. The purposes of this study were (1) to develop a human relations component to be used in an introduction to education course; (2) to utilize the component in an actual teaching situation; and (3) to examine the effects of the course on the self-concept and interpersonal relations of secondary education pre-service teachers. The results of the statistical analyses revealed that the differences between the experimental and control groups on measures of the self-concept and interpersonal relations were not statistically significant. No significant gains were made by the experimental group on both criterion measures. Findings derived from personal observations indicated that the experimental group became aware of the affective dimension of the teaching-learning process. It was also evident that factors in addition to increased scores should be considered in research concerning enhancement of the self-concept and interpersonal relations.

Anxiety Relief, Progressive Muscle Relaxation, and Expectancy Relaxation in the Treatment of Speech Phobia
Relaxation procedures and anxiety relief were reviewed. Effects of cognitive and expectancy variables in reduction of avoidance behavior were also extensively reviewed. Various theoretical models for desensitization were presented. Use of symbolic control in classical conditioning and use of self-control methods in anxiety reduction were discussed. Special emphasis was given to self-desensitization and cue controlled relaxation. One goal of the experiment was to determine whether a musical stimulus associated with counter anxiety procedures could reduce or prevent subjects' phobic responses in the presence of the phobic situation. Another goal was to determine the relative efficacy of two counter anxiety procedures (anxiety relief and progressive muscle relaxation) in lowering muscle tension and in reducing or preventing speech anxiety. Several implications were drawn from the study. Relaxation alone may alleviate anxiety and phobic behavior without being paired with phobic stimuli. Cognitive variables such as expectancy and feedback of progress make a substantial contribution to treatment of situational anxiety. Progressive muscle relaxation may not be the technique of choice for producing low levels of muscle tension. Recommendations for future research were specified, including additional measures and control procedures.

A Study of the Contributions of Mary Lizzie McCord to Drama Education at Southern Methodist University
Although in 1915 there was no drama education in Methodist colleges and universities in Texas, today all Methodist schools of higher education in Texas have at least course offerings in drama. Southern Methodist University was one of the first Methodist schools to offer such courses which began with the hiring of Mary McCord to teach public speaking in September, 1915. The problem of this study is to explain the contributions of Mary McCord to the development of drama education at Southern Methodist University. It is recommended that the development of the department after Miss McCord retired be examined, that the students taught by Miss McCord who chose theatre as their life's work be interviewed about the effect of her training on their careers, and that a thorough study of the McCord Theatre Collection be undertaken.

Implementation and Administration of Radical Education in Texas: Politics or Reform in Education from 1870-1873
This study examines the efforts of Radicals (Republicans) to establish a state-wide public school system in Texas between 1870 and 1873. Primary sources cover the chronological fringes of the period being examined. This study follows a chronological narrative with the four chapters examining first, educational trends in the southern states and Texas prior to Reconstruction, followed by examination of the Radical system in Texas, and, finally, its destruction by Conservative Texans. The final chapter focuses on immediate and long range results of Radical education. In examining the Radical educational program, an attempt has been made to dispel ideas popularly held by present-day Texans who believe that the Radical school program was simply another "carpetbagger" scheme for raiding the state treasury and building Radical patronage. This paper contends that the Radicals established as good a public school system as could be created at the time, and that it was administered in an honest and efficient manner. The system was destroyed by politicians and a grass roots revolt of taxpayers who had no faith in its methods, goals, or administrators.
