The general purpose of the study was to determine the relationship between college environmental press variables and the attrition characteristics of college freshmen at Southern Methodist University.

The ancient Germanic god that Richard Wagner resurrected in his operatic style Der Ring des Nibelungen was worshiped and feared from Greenland to Asia Minor for 1,000 years after the birth of Christ. This thesis examines the psychological aspects of Wotan as he appears in the opera.

This study examines the development and creation of the clarinet in the seventeenth and eighteenth century, and the start of their use as a solo instrument in the eighteenth century. This explores Mozart's utilization and development for the clarinet to other various composers and their contributions.

Sowerby's compositions based on hymn tunes cover the extent of his career - from 1913 to the time of this study. There are two purposes in selecting them for study: to describe the development of Sowerby's musical style; and to show, from a study of these compositions, the various devices, forms, and techniques which are effective in this area of composition in general.

The principle problem of the present research was to determine the relative effects of two major variables, nature of verbal reinforcement and achievement history, upon the performance of elementary school children on a relatively simple learning task.

This study looks at Aelfric's "Passion of Saint Sebastian, Martyr" from an etymological perspective.

This is a study of families that had pregnancies while they were recipients or potential recipients of public assistance.

The purpose of this investigation was to study the scattering processes of K+ mesons with neutrons. In order to do such a study one must first make certain basic assumptions about the type of interaction involved and then proceed to calculate physically meaningful qualities which describe the processes. Thus, the problem is this: assuming the validity of Feynman's rules for these strongly interacting particles, calculate the differential and total scattering cross sections for the interaction of scalar K+ mesons and neutrons.

Despite the importance of the Slave Trade Question in European diplomacy from 1807-1822, historians of this period have neglected it in order to concentrate on Napoleon and the reconstruction of Europe. Scholars of Negro history generally have traced the slave trade up to 1807 and then have turned to the emancipation movement. This thesis represents an attempt to satisfy the need for a diplomatic study of this issue.

The federal administrative structure has undergone many changes as a result of governmental reorganizations. In analyzing one of these various reorganizations, the author was convinced that though there were many reasons for change, the plans were based on some set ideas, congenial to the efficient working of governmental machinery. This study will demonstrate how the principles of public administration are employed and emphasized in the reorganization plans.

It was the purpose of this study to determine the relationship between a subject's performance as revealed by intellectual indices of the Rorschach, his intellectual ability as revealed by the Wechsler Intelligence Scale for Children, and academic success or failure in the form of promotion or nonpromotion.

The primary purpose of this thesis is to carefully develop and prove some of the fundamental, classical theorems of the differential calculus for functions of two real variables.

Since Djerassi and Scholz found that 2-(aryloxy-methyl)imidazolines and their hydrochloride salts exhibit vasoconstrictive properties, the 1,2-(I) 1,3-(II) and 1,4-bis-(2-imidazolinylmethoxy) benzene (III) analogs (Fig. 1, p.2) were chosen for synthesis in order to test them for their effective vasoconstrictive characteristics and for whatever other physiological properties they might exhibit.

For this work, the decision was made to contrast two serological tests, that of the tube agglutination technique and the fluorescent antibody technique for correlation with the coagulase and other characteristics of Staphylococcus strains. This has been a preliminary survey in the hope that as further knowledge is obtained about the staphylococci, grouping of the organisms will become more routine and relatively less complex.

This thesis describes the rules of prepositions in English adverbial phrases.

It will be the purpose of this thesis to comment upon the five novels by Gironella published to date, with special consideration given to the religious aspects which are found in them. Gironella's attitude toward the Catholic Church and its representatives will also be examined, particularly in regard to the role which the Church and its priests played in the Civil War.

The purpose of this research is to provide a descriptive study of selected social and psychiatric characteristics of adolescent first admissions to a private psychiatric hospital and an analysis of some of the inter-relationships among social, ecological, demographic and psychiatric variables selected for study.

The purpose of this investigation was to study some of the transport effects in a single crystal of arsenic at liquid helium temperatures in a magnetic field up to twenty-four kilogauss. The experimental coefficients determined were the isothermal magnetoresistivity and the isothermal Hall resistivity.

The pyrolysis of sec-butyllithium in solution was studied in an attempt to understand the loss of stereo-specificity and the atypical kinetics that have been reported. Additionally, the effect of added lithium alkoxides was studied to determine their effects on the highly reactive sec-butyllithium substrate.

This research is concerned specifically with the growth of two selected algae found surviving in chlorinated water in outdoor swimming pools. Unialgal cultures were used to determine the free chlorine residuals that these algae were able to tolerate.

The purpose of this study is to investigate the possibility that the handwriting analysis of a particular group of individuals with homogeneous interests and abilities (mathematics majors, music majors, psychology majors, and education majors) could likewise identify and isolate a particular personality variable common to these individuals.

It was the purpose of the present study to compare the effect of intraperitoneal injections of the following drugs on a conditioned approach-avoidance response in mice. These drugs were epinephrine and nor-epinephrine.

This thesis provides a development of integration from two different points of view. In Chapter I, a measure and a measurable function are defined. A theory of integration is then developed in Chapter II based on the measure. In Chapter III, the integral is introduced directly without first going through the process of defining a measure, and a measure is developed from the integral. The concluding chapter shows the equivalence of the two integrals under rather general conditions.

This paper is an introductory, algebraic study of semigroups.
