This open access book revisits common notions on how to select and recruit the right employees. It reveals that the secret of successful individuals and teams lies in a combination of talent and four important performance indicators, offering an innovative approach that companies can fruitfully adopt. Bas Kodden has studied key performance indicators among over 1,100 executives, senior staff and professionals, including 50 CEOs from leading Dutch companies. His findings put the present recruitment and selection procedures used by many prominent companies in a new light. Moreover, the book not only addresses theory; it also offers a practically applicable model for recruitment, selection and professional development. In closing, the book includes a variety of questionnaires and checklists for HR professionals and executives whose goal is to build sustainable and successful teams and organizations.

Purpose of the study. The purpose of this study was to determine if teacher feedback to sung tonal patterns affected the music self-concept of sixth and seventh grade students. General self-esteem was also tested for correlation with music self-concept. Procedures. One hundred students in sixth and seventh grades from three middle schools in Columbia, Missouri participated in this study. Each student completed the Coopersmith Self-Esteem Inventory and the Self-Concept in Music scale in a large group setting. These two scores for each student were used to place students in one of four subgroups: high general self-esteem/high music self-concept, high general self-esteem/low music self-concept, low general self-esteem/high music self-concept, and low general self-esteem/low music self-concept. The students were then randomly assigned to one of three treatment groups (no feedback, appropriate feedback, positive feedback). The students, in a private session, attempted to echo-sing seven tonal patterns. The researcher responded to each attempt according to the assigned treatment and recorded the singing performance scores. Each student then completed the Self-Concept in Music scale once again. Results. No significant main effects or interactions were found. A low positive significant correlation (r =.37) was found between the scores for sung tonal memory and the posttest scores for music self-concept. A low positive significant correlation (r =.28) was also found between the scores for the music self-concept pretest and the scores for general self-esteem. Conclusions. Results of this study validate that students are able to determine their own perception of ability in music, that this perception is stable after a short-term intervention, and that this perception significantly relates to their general self-esteem.
