The problem was to determine the significance of various relationships between job-performance ratings and selected factors associated with the college curricula of junior executive trainees. Job-performance ratings were made by personnel directors and immediate supervisors of college graduates enrolled as participants in junior executive training programs in department stores in Texas.

The main purpose of this paper is to make a detailed study of a certain class T of complex functions. The functions of the class T have a special mapping property and are meromorphic in every region. As an application of this study, certain elementary functions are defined and studied in terms of a special T-function.

Both science and empirical knowledge seem to indicate that anatomical considerations relating to potential muscular interference be established at the incipiency of the serious study of voice. Experience shows that if this aspect of vocal development is not pursued with utmost diligence, an early deterioration of the vocal instrument is possible many years before a normal expectancy. It has been discovered, also, that the study of articulation, pronunciation, modulation, emphasis, gestures and interpretation seem to avoid, primarily, the necessity of muscular training, per. This thesis will not include, in detail, the aspects of the use of the breath, except in a perfunctory manner. The same can be said of resonance and diction. It will endeavor, however, to indicate the muscular differences of the singing and swallowing actions. Furthermore, it will advance some suggestions for the avoidance of constrictive muscular influences which might impede the singing musculature. Finally, a phonatory process will be presented for consideration as a muscular mechanism to be made operative in connection with a direct control procedure.

The problem of the study was to determine the effectiveness of an in-service education program as a means of providing qualified foreign language teachers for elementary schools. Specifically, the problem was concerned with a statistical comparison of the achievement of two groups of pupils. One group was composed of fourth-grade pupils who were taught Spanish by teachers who had had a maximum of three college hours in Spanish and who had participated in an in-service education program. The other group was composed of fourth-grade pupils whose teachers had had a minimum of twelve college hours in Spanish but had not participated in an in-service education program.

By presenting first, statement of theory, and then concrete examples and original exercises, wherever practical, this thesis suggests possible ways to combine linguistic methods with traditional ones to make a more effective approach to teaching language in the ninth grade.

This study is an attempt to determine the effects of proximity to a large urban center on selected changes in agriculture.

The specific goal of the investigation was the measurement, as a function of temperature, of the self-diffusion coefficients of Pb210 and Cl36 in PbCl2-KCl compositions in the region of the first compound, and to calculate from these data the activation energy necessary for the diffusion of these ions.

This study has two divisions: Part I, an historical and analytical summary of the emergence and development of the divertimento and the serenade in the eighteenth century, and Part II, the culmination of these structures in the works of W. A. Mozart. Two primary purposes are envisioned: 1) to further our knowledge of how German Gesellshafts-musik evolved toward its peak in the second half of the eighteenth century, and 2) to furnish a useful analytical handbook of Mozart's works in these genres.

This thesis is a study of fundamental properties of Hilbert space, properties of linear manifold, and realizations of Hilbert space.

Most of Domenico Scarlatti's harmonic progressions are quite orthodox when considered abstractly or free of their positioning in the score. The harmonic movement is given interest by subtle alterations in time; for example, (1) simultaneous upper and lower voices of different lengths, when repeated several times, change their relationship with each other; (2) one voice may be simply delayed so that it lags behind the other voice, thus combining to produce irregular harmonic sound on many succeeding beats; (3) the combination of two or more chords appearing on one beat is similar to number (2) but does not necessarily occur more than once.

Born April 2, 1873, on the estate of Oneg in the province of Novgorod, Russia, Sergei Vassilyvitch Rachmaninoff was the fifth of the six children of Vassili and Lyoubov Boutakova Rachmaninoff. Rachmaninoff's aristocratic descent was traced to the Hospodars Dragosh, rulers of the realm of Molday from the fourteenth to the sixteenth century. One of the daughters from this family had married a son of the Grand Duke Ivan III of Moscow. The son's nephew was named Rachmanin, and from this source the family name originated.1 Rachmaninoff's mother was the daughter of a general, head of Araktcheyev Military College in Novgorod and the owner of a number of estates in the district. It was with a dowry of five of these estates that Lyoubov Boutakova married Vassili Rachmaninoff, and on one of these estates, Oneg, the couple settled down to married life.

"The purpose of this thesis is to examine the age structure of the population of Texas as it existed in 1960, and insofar as possible to trace important changes and trends in the older group from 1900 to 1960. The qualification derives from the fact that at this time not all of the data from the 1960 census are available, and hence many trends can be described only through 1950. Where appropriate, the structure and trends characteristic of the total population will be described, usually for comparative purposes."-- leaf 1.

Undoubtedly, Dostoyevsky's influence upon the novel is great, but, even yet, few concrete studies have been made and no full-length study has been published. It is hoped that this account of Dostoyevsky's reputation in America during the 1920's will be of assistance in the greater task of tracing Dostoyevsky's influence.

In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.

The problem of this study was to determine the effectiveness of student-centered teaching in producing significant changes in certain critical thinking abilities among selected freshmen students at North Texas State College.

"The purpose of this study was to collect and analyze locational data on all branch maufacturing plants established in Dallas County in 1954, 1955, and 1956; these data were acquired through personal interviews in 1957. For comparative purposes the same data on branch plants established in 1959 were obtained in 1960. The following elements of the locational process were determined and analyzed: 1. Origin and character of the new plants; specifically location of home office, types of products, size and location of the plant in Dallas. 2.locational process, including company personnel assigned the task of locating a suitable site and local agencies assisting in the locational process. 3. reasons for establishing the branch plant 4. factors that influenced management to locate the plant inDallas in preference to any other locations."-- leaf 4.

It was the purpose of the present investigation to determine if sensitivity to other antibiotics can likewise be affected by subjecting S. aureus to heparin contact. It is of special interest in this problem to determine whether heparin in some manner affects the combining process of penicillin with the cells of several strains of S. aureus.

The present study was made to determine the relationship between the level of teaching effectiveness of beginning elementary teachers and three individual characteristics of prospective teachers. A secondary purpose was an attempt to improve the service rendered by the School of Education at North Texas State College, Denton, Texas, in the selection and guidance of students who indicate a desire to enter the program for preparing elementary teachers.

The history of the Osages from 1808 to 1839 may be conveniently divided into three major sections, each separated by a cession treaty. The first begins with the cession treaty of 1808 and terminates with the cession of 1818. It covers the Osages' relations with the whites and the eastern tribes during that decade. The second section begins with the 1818 session treaty and ends with the land cession of 1825. It likewise covers the tribe's relations with the eastern tribes and the whites. The concluding division covers the period from the Osages' last major cession treaty to their removal to Kansas in 1839, and includes their relations with the eastern tribes, the western tribes, and the whites. These three sections combined cover the most turbulent period in Osage history, a period in which the United States Government and the powerful eastern tribes took the extensive Osage lands by right of conquest.

The purpose of this paper is to present a study of partly ordered sets. It includes a rigorous development of relations based on the notion of a relation as a set, lattices, and theorems concerning the lattice of subgroups of a group.

The problem of this study was to determine whether there is a significant relationship between certain situational factors and high and low scores on the leadership behavior dimensions of industrial supervisors. The behavior dimensions studies were the two dimensions of Consideration and Initiating Structure, as measured by the instrument used in the study.

This paper investigates the Runge-Kutta method of numerically integrating ordinary differential equations. An existence theorem is given insuring a solution to the differential equation, then the theorem is modified to yield an analytic solution. The derivation of the method itself is followed by an analysis of the inherent error.

It is the purpose of this study to utilize three psychometric measures in order to quantitatively assess the group of subjects on the basis of the trait heterosexuality, as measured by the Edwards Personal Preference Schedule, and in turn make predictions on the basis of these data as to choices made on the Bonney-Fessenden Sociograph.
