• Abstract: Thought leadership plays a crucial role in boosting team performance; thus, teams with more thought leaders may perform better. However, the impact of the number of thought leaders on team performance in a scientific context remains understudied. In this study, we consider the authors of a publication as a scientific team and define authors responsible for conceptual tasks, such as conceived and designed the experiments in the PLOS contribution statement classification system, as thought leaders. Leveraging more than 140,000 papers from PLOS journals, we examine the relationship between the number of thought leaders and two aspects of team performance, namely team impact and team disruptiveness, from both correlational and causal perspectives. The results show that (1) an inverted U-shaped relationship exists between the number of thought leaders and team impact, and (2) teams with more thought leaders tend to produce less disruptive ideas. We also explore how international collaboration, team size, and gender diversity interact with the number of thought leaders in shaping team performance, and find that (3) international collaboration improves team impact but lowers the disruptiveness of team outputs. This study advances scholarly understanding of thought leadership in scientific teams and provides valuable insights for policymakers and team managers.

  We show how individual activities cohere into broad roles of leadership through the direction and presentation of research. The hidden hierarchy of a scientific team is characterized by its lead (or L)-ratio of members playing leadership roles to total team size. We find that relative to flat, egalitarian teams, tall, hierarchical teams produce less novelty and more often develop existing ideas.

  This research examines in depth the relationships between team power and team success in the field of Computer Science.

On the contrary, low-power teams with hierarchical structure is a facilitator of team performance.

  In real-world multiagent systems, agents with different capabilities may join or leave without altering the team's overarching goals. We propose COPA, a coach-player framework to tackle this problem. We 1) adopt the attention mechanism for both the coach and the players; 2) propose a variational objective to regularize learning; and 3) design an adaptive communication method to let the coach decide when to communicate with the players.
