The purpose of the study was to write a history of the professional career of D. O. Wiley as a music educator from 1921 to 1963. To give focus to the career of Wiley, answers were sought to three questions, stated as sub-problems: (1) What were the important events and influences in the professional career of D. O. Wiley as a college/University band director? (2) What impact did Wiley have on the development of Texas public school bands that earned him the title "Father of Texas Bands?" and (3) What role did Wiley play in the development of the Texas Music Educators Association and other professional music organizations.

Genetic variation and thermal tolerance were surveyed for variation attributed to nonuniform selection pressures for five populations of the red shiner, Notropis lutrensis, collected from regulated and unregulated portions of a Texas river. Populations within 30 km of a hypolimnion-release dam that experience large thermal perturbations were found to have higher levels of heterozygosity, higher levels of polymorphism, significantly depressed levels of upper thermal tolerance endpoints, and greater variances in tolerance endpoints. These populations have evolved enzyme systems differing from the unregulated populations in response to a variable and depressed thermal regime.

The purpose of the study was to examine the relationship between the professional activities of Col. Earl D. Irons and the overall development of bands in the Southwest. The need for the study was determined after researching the related literature, which revealed gaps in the historical record of instrumental music education, and in particular a dearth of biographical studies dealing with music educators in band field.

This empirical study is concerned with the extent to which news announcements affect the performance of common equity securities of oil and gas producing companies. The market effects of news announcements are considered to be of importance in resolving two issues. One concerns financial statement disclosure and the second concerns examination of prior oil and gas industry-related accounting research. This dissertation assumes capital market efficiency and addresses two research questions: do news announcements concerning activities of nonintegrated oil and gas producing companies affect the companies' common stock prices, and are announcements concerning nonintegrated oil and gas companies' financial, personnel, explorational, and developmental and operational activities used equally by investors in their decision-making?
