The influence of age on volunteer contributions in a nonprofit organization
研究458名志愿者在74个团队中的表现，发现成员选拔质量对年长志愿者的角色内绩效影响更大，培训质量对年龄相似度高的志愿者更有效，且年龄对助人行为的正向作用在平均年龄较大的团队中更强。
Abstract This study examines the role of chronological age and age diversity in relation to the effects of organizational influences on the contributions of 458 volunteers in 74 geographically dispersed teams of a large nonprofit organization. The results indicate that the quality of member selection has a greater positive influence on in‐role performance for older rather than younger volunteers that the quality of training for group members has a greater positive influence on in‐role performance for volunteers who are less dissimilar in age from others in the group, and that the positive effects of chronological age on helping behaviors depend on the mean age of the group such that it is stronger for groups with older age means. The findings are discussed along with their practical implications. Copyright © 2007 John Wiley & Sons, Ltd.
