In this paper we address the stabilizing token circulation and leader election problems in population protocols model augmented with oracles. Population protocols is a recent model of computation that captures the interactions of biological systems. In this model emergent global behavior is observed while anonymous finite-state agents(nodes) perform local peer interactions. Uniform self-stabili...

This study advanced knowledge on charisma by (a) introducing a new personality-based model to conceptualize and assess charisma and by (b) investigating curvilinear relationships between charismatic personality and leader effectiveness. Moreover, we delved deeper into this curvilinear association by (c) examining moderation by the leader’s level of adjustment and by (d) testing a process model ...

This paper examines the relationship between a leader’s unconventional behavior and followers’ creative performance at both the individual and group level in an experimental setting. Our results indicate that after transformational leadership and individual intrinsic motivation for creativity are controlled for, unconventional leader behavior (e.g., standing on furniture, hanging ideas on cloth...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

WILL greatly increase our understanding of leadership phenomena if we abandon the notion of "leadership" as a trait, and concentrate instead upon an analysis of the behavior of leaders. It is not easy to accomplish this shift in viewpoint, for our ways of thinking about "leadership" have been encumbered by many beliefs not in accord with be havioral facts. The problem is further exacerbated bec...

This paper presents a state space model for a multiperson ensemble and an estimation method of the onset timings, tempos, and leaders. In a multiperson ensemble, determining one explicit leader is difficult because (1) participants’ rhythms are mutually influenced and (2) they compete with each other. Most ensemble studies however assumed that one leader exists at a time and the others just fol...

We analyze an agency model of political competition to examine whether con‡ict encourages hawkish behavior, and if such behavior can itself aggravate con‡ict. We consider situations of con‡ict between a state and an insurgent group, such as con‡ict over a piece of land. Negotiations are carried out on behalf of the state by a democratically elected leader whose ability and ideology are imperfec...

Mobile robots are envisioned to provide more and more services in a shared environment with humans. A wide range of such tasks demand that the robot follows a human leader, including robotic coworkers in factories, autonomous shopping carts or robotic wheelchairs that autonomously navigate next to an accompanying pedestrian. Many authors proposed follow-the-leader approaches for mobile robots, ...

Here we study the emergence of spontaneous collective leadership in large populations. In standard models of opinion dynamics, herding behavior is only obeyed at the local scale due to the interaction of single agents with their neighbors; while at the global scale, such models are governed by purely diffusive processes. Surprisingly, in this paper we show that the combination of a strong separ...

in last decade, with the entry of spirituality in organizational and managementresearch, spirituality leadership, also, has attracted a considerable amount of attention.in this study, with a developmental approach and after using experts' opinions andliterature for identifying leaders' spiritual traits and behaviors, we aim to model themusing adaptive neural-fuzzy inference systems. e...
