The eightfold purpose of this study was: 1. to evaluate the programs of boys' clubs sponsored by organizations in McKinney, Denton, and Dallas, Texas; 2. to obtain and study the aims and objectives of the programs of each club; 3. to obtain and study the aims and objectives of the active membership of the clubs; 4. to evaluate the programs in the light of an over-all guidance program; 5. to determine the different activities and their significance of mental, physical, emotional, economical, social, and moral phases of life; 6. to determine the social and economic status of the membership of the clubs; 7. to discover in which clubs there is a definite need for future professional preparation of adult leaders; 8. to discover the carry-over value of adolescent training through clubs into adult life.

It was the purpose of this study to investigate some of the factors related to employers' attitudes toward the hiring of a mentally retarded individual. More specifically, an attempt was made to answer the question, "Why do employers hold favorable or unfavorable attitudes toward the hiring of the retarded?"

The purpose of this study is two-fold: (1) to evaluate an instrument for measuring the self-concept of middle grade children; and (2) to determine the relationship of a middle-grade child's self-concept to his peer status, his classification by the teacher as a problem in behavior or classroom management, and to his academic achievement.

Mental imagery is a common theme in research that clarifies how musical thought relates to musical performance. Unfortunately, minimal information exists regarding mental imagery and singers. The purpose of this study was to probe the role, if any, mental imagery plays in the conceptualization of pitch and vowel. By interviewing singers at differing levels of expertise, basic information was obtained about the mental processes used by singers. Through evaluations of the singers' mental processes, it was concluded that 95% of the singers in the study employed mental imagery. All singers described using kinesthetic imagery, while the majority implemented sensory and auditory imagery. Viso-spatial imagery was implemented among the more experienced singers. The majority of singers also reported: imaging pitch and vowel interactively; imaging from an internal perspective; and utilizing mental rehearsal. Less than half of the singers described using methods other than mental imagery to conceptualize pitch and vowel.

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

This study addresses an individual's performance, relating it to eyesight changes due to the aging of the individual and to color computer screens used for computer-based-instruction not designed specifically for older students. This study determines how existing research in gerontology, human-computer interface, and color use in visual graphics can be applied to the design of computer screen displays containing color text and backgrounds and how various color combinations will affect performance by adult learners forty years of age and older. The results of this research provide software developers and instructional designers guidelines to use when designing computer screen displays for use in instructional computing settings involving older adults.
