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.
