Cognitive versatility and adaptation to fluid participation in hospital emergency department teams.

Role-based frameworks have long been the cornerstone of organizational coordination, providing clarity in role expectations among team members. However, the rise of "fluid participation"-a constant shift in team composition and skill sets-poses new challenges to traditional coordination mechanisms. In particular, with fluid participation, a team's roles can oscillate between disconnected and intersecting, or between lacking and having overlap in the capabilities and expectations of different roles.

Moral beacons: Understanding moral character and moral influence.

Objective: We introduce the concept of moral beacons-individuals who are higher in moral character than their peers and prominent within their social environment-and examine the degree to which moral beacons increase the moral awareness of their peers.

Background: Using data from cohorts of students in graduate business education across two universities, we applied theory and methods from organizational behavior, personality psychology, and social networks analysis to test two research questions about moral beacons.

Method: We used latent profile analysis of data from personality questionnaires and social network surveys completed by graduate business students at two universities (N = 502) to identify individuals classified as moral beacons.
