In order to determine the effect of radiation on the structure of native shortgrass plains vegetation, an 8750 Ci 137Cs source was installed on the Central Plains Experimental Range near Nunn, Colorado; The experimental area was divided into 6 treatment sectors, a control, 2 sectors for chronic exposure (irradiation initiated April 1969 and continuing as of August 1971), and one each for spring, summer and late fall seasonal semi-acute (30 day), exposures which were administered during April, July and December, 1969, respectively. Community structure was measured by coefficient of community and diversity index. Yield was determined by clipping plots in September 1970 and visual estimates in September 1969 and 1970 for the grass-sedge component of the vegetation. Individual species sensitivity was determined by density data recorded in April, June and September of 1969 and 1970 and by a phenological index recorded at weekly intervals during the 1969 and 1970 growing seasons. The response of the vegetation was similar whether determined by coefficient of community or diversity with diversity being a more sensitive measure of effects. In the chronically exposed sectors, the exposure rate which resulted in a 50 per cent reduction in these 2 parameters (CC50 or D50) was still …

The purpose of this study was to determine the interrelationship of self-concept and attitude toward mathematics to academic achievement in the areas of arithmetical computation, concepts, and application.

The problem with which this investigation was concerned was to measure personal adjustment, emotional adjustment, home adjustment, and self-concept changes that took place in junior college students as a result of one-counselor group counseling and male-and-female co-counselor group counseling. The rationale for male-and-female co-counselor group counseling relied on the formation of a simulated family in which individuals could socialize their feelings.

In the southwestern United States there is a delicate balance between the existing grasslands and the rodent fauna. The purpose of this investigation was to determine the influence of secondary succession of native grasslands upon the ecology and distribution of small rodents. Two methods of determining the rodent species were plot quadrates and trap lines using Sherman live traps.

The problem of this study was to determine the value of certain selected aptitude test scores for predicting student achievement in Spanish, French, and German at North Texas State University. Particular emphasis was placed on freshmen enrolled in beginning courses.

This study was undertaken to investigate the predictive value of certain tests in relationship to first grade reading success. The following predictor tests were administered to seventy first grade students during the first two weeks of school: Metropolitan Readiness Test, Naming Letters Test, Light Response Test and Matching Symbol Test. The Teacher's Reading Readiness Rating Scale was filled out by each of the seven teachers at the end of the sixth week. The Wechsler Intelignce Scale for Children was administered to each child during the fall. The seventh predictor test was computed by finding the difference in individual scores of the Light Response Test and the Matching Symbol Test.

The lecture recital was given January 31, 1971. A discussion of Bartok's Out of Doors, a suite consisting of five movements entitled "With Drums and Pipes," "Barcarolla," "Musettes," "The Night's Music," and "The Chase" included biographical material, general analysis of Bartok's musical style, and specific analysis of the suite itself. The suite was then performed by memory. In addition to the lecture recital three other public recitals were performed. Two of these consisted entirely of solo literature for the piano, and the other was a vocal chamber music recital. The first solo recital was on June 7, 1970, and included works of Alfredo Casella, Beethoven, Chopin, Brahms, and Bartok. Part of the preparation included the writing of program notes of a historical and analytical nature.The other solo program, on July 5, 1971, consisted entirely of twentieth-century works by George Rochberg, Sergei Prokofieff, and Maurice Ravel. The chamber music recital was performed with a visiting soprano, Jane Paul, on February 28, 1971. Emphasis was given to German Lieder by Schumann, Joseph Marx, and Alban Berg, but Spanish songs of the Renaissance, by Juan del Encina and Fuenllana, as well as a modern English song cycle by Peter Warlock were also programmed.

This dissertation examines the relationship between computer technology and management science and changes in the role of profit planning within the commercial banking system of the U.S.A. The objective of the study is to develop a generalized profit-planning model which employs the existing decision processes to create pro-forma financial statements for a commercial bank. The study concentrated on the 300 largest commercial banks (ranked by deposits as of December 31, 1969) of the Federal Reserve System. These particular banks held the greatest potential for having a Planning Department, the computing capability necessary for problem solving, and a Management Science Department actively employing management science techniques to profit-planning problems. The research for the dissertation included an in-depth study of secondary sources, an interrogation of commercial bank executives and a detailed questionnaire which was submitted to each of the 300 largest banks. Sponsorship for the Financial Planning Questionnaire was obtained from the Southwestern Graduate School of Banking at Southern Methodist University, Dallas, Texas. The sponsorship helped obtain a large sample return (in excess of 50.0 percent) and thereby increased the statistical reliability of the results of the study.

The lecture recital, "Thema med Variationer, Opus 40, By Carl Nielsen" presented a discussion of the composer's general background and the characteristics of his style. Specific points made were related to the Thema med Variationer; the discussion was followed by a performance of the work in its entirety. In addition to the lecture recital, three other recital programs were organized and public concerts presented to provide the platform for the works studied. Two of these programs were of solo piano music and one was of chamber music with the clarinet and viola in partnership with the piano. All programs were recorded on magnetic recording tape. The spoken portion of the lecture recital in written form is filed with the recordings as a part of this dissertation.

The lecture-recital, The Development of Woodwind Fingering Systems, traces the evolution of devices for controlling the pitch produced by woodwind instruments from prehistoric times to the present. The addition of keys, and the evolution of collections of individual keys into coordinated systems is particularly stressed, as are the various physical, physiological, and cultural forces which determined the directions of development of these systems. The similarities between the fingerings of various woodwind instruments are explained, a system of numbers is introduced in order to clarify these similarities, and a projection of some possibilities for future development of woodwind fingering systems is offered.

The problem with which this study is concerned is that of ascertaining the effects of intensive Remotivation Techniques on institutionalized geriatric mental patients in terms of their ward behavior, self-concept, and visual-motor perceptions and to compare these with the effects of a similar group experience that does not emphasize patient-staff or patient-patient interactions, and a third group which acts a a control. The investigation is designed to answer or obtain information concerning the following questions: (1) Do institutionalized geriatric mental patients in a state mental hospital manifest measurable changes in terms of their (A) ward behavior as defined as raw scores on the Hospital tment Scale (including interpersonal communication and interpersonal relations; self care and social responsibility; level of participation in ward activities, recreation and work therapy; total score), (B) self-concept as defined as Goodenough raw scores on the Draw-a-Person Test, and (C) awareness of environment as defined as Pascal and Suttell raw scores on the Bender Visual-Motor Gestalt Test, as a result of experiencing the social and verbal interactions of intensive Remotivation Techniques? (2) Is the Remotivation Technique more effective in producing these changes than a similar group experience that does not emphasize social and verbal interactions?

The initial intent in regard to the story line for this work was to utilize an authentic Hispanic-Southwestern folk tale. It was found, however, that the predominance of recorded folk tales was lacking in sufficient plot involvement. It was decided therefore, that a plot would be constructed by the composer using Hispanic folk material. Elements of recorded folk tales are used in the story to maintain the folk-like quality. Some of these elements are a mutual respect among family members, an acceptance of superstitious ideas, a dependence upon a person claiming supernatural powers, the embodiment of the devil in a person or animal, and the punishment of the wayward girl by the devil.

Concerto for Piano and Orchestra is a three movement composition. The performance time of the entire composition is approximately nineteen and one-half minutes. Certain melodic similarities are found in the three movements of this composition because some of the pitch successions selected for motives were derived from a twelve tone row. The harmonic sonorities are based on free choice and derivations from the tone row as were the melodic materials. The rhythm in this work is not serialized or in any other way predetermined.

The removal of phenols from the waste waters of wood preserving plants has always presented problems. The purpose of this paper is to investigate the possibility of employing a biological system to reduce the phenol content of effluent from these plants.

The problem with which this study is concerned is the importance of music in the life and poetry of Emily Dickinson. The means of determining this importance were as follows: (1) determining the experiences which the poet had in music as the background for her references to music in the poems, (2) revealing the extent to which she used the vocabulary of music in her poems, (3) explicating the poems whose main subject is music, (4) investigating her use of music in the development of certain major themes, and (5) examining other imagery in her poetry which is related to music.

The problem with which this investigation is concerned is that of determining how Francisco Garcia Pavon's concept the detective novel evolved throughout the period during which he cultivated that literary form. To trace this evolution Garcia Pavon's detective novels and novelettes are studied in chronological order of publication, each work being given a chapter of its own. The character development is analyzed and the style is given consideration in the study.

The problem undertaken is a study of the Senate's right to refuse confirmation of presidential nominations to the Supreme Court of the United States and its interpretation of this constitutional prerogative today.

There are two general approaches to myth, the literal and the symbolic. The literal method considers myth a record of man's responses to factors external to himself, while the symbolic approach evaluates myth as the externalization of internal conflicts. The purpose of this paper is to examine several examples of each type of scholarship and to show the efficacy of both in gaining a complete understanding of the Oedipus myths.

This study involved an evaluation of laboratory manuals available to high schools for use with electricity training systems to ascertain which-were most adequate in meeting curriculum standards for general electricity as specified in Bulletin 615 of the Texas Education Agency.

This study describes meaning changes that have occurred in the native word stock of English. Since no existing studies are devoted solely to investigating semantic change in Old English words, this study tries to illustrate word histories through examples of usage in the past and by a discussion of causes for change.

An attempt was made to further establish the validity of the Polyfactor Test of Marital Difficulties, a relatively new, yet potentially valuable sentence completion, self-rating marital difficulties test. . Another test, the Marital Adjustment Inventory was also used for comparison purposes.

The thesis states that women characters in the works of Ramuz have much more depth, life and variety than first meets the eye. In order to demonstrate this, it was decided to show women characters, main, secondary and in groups, and to look at their presentation in the novels recognized generally as the most important.

This study was an effort to objectify and test empirically Tillich's theory. Its purpose was to investigate certain traditional aspects of religion to see whether their presence was associated with purposefulness in life. The variables used in this study were measures of participation in a faith, belief in an afterlife, belief in God, past and current doubts, religious experiences, commitment implied in the consideration of a church related vocation, and of purpose in life. Tillich would say that participation in a faith, a belief in God, and a commitment of some kind are essential elements of one's ultimate concern. The belief in an after life is a common way of avoiding the anxiety of death, which is an element of the anxiety of meaninglessness of today. Doubt concerning the Ultimate undermines ones meaning or purpose in life.

The purpose of this study is twofold: the first and most important purpose is to examine the various forms of humor; the second is to present views of the author concerning universal topics.
