Recent literature models leadership as the process of communication where the rhetorical signals of leaders facilitate followers’ coordination. While studies exist that explored the effects of leadership in experimental settings, there remains a lack of empirical research on the effectiveness of informational tools in real political environments. Using quantitative text analysis of federal and ...

Cooperative localization (CL) is considered a promising method for underwater localization with respect to multiple autonomous underwater vehicles (multi-AUVs). In this paper, we proposed a CL algorithm based on information entropy theory and the probability hypothesis density (PHD) filter, aiming to enhance the global localization accuracy of the follower. In the proposed framework, the follow...

Initiating and sustaining sufficient levels of participation among residents in low-income and urban neighborhoods have become significant focuses of many initiatives that strive to develop healthy communities. This study examines the factors associated with citizen participation levels in resident leaders and followers in seven low-income neighborhoods in one community. Overall, the findings s...

Building on fairness heuristic theory, fairness theory, and trust development models, we argue that unfairly enacted procedures decrease followers' trust in the authority particularly when authorities have high power over their followers. Moreover, we expected trust to mediate procedural fairness effects on followers' attitudes (authorities' legitimacy and charisma attributed to authorities) an...

What is the role of leaders in large organizations? We propose a model in which a leader helps to overcome a misalignment of followers’ incentives that inhibits coordination, while adapting the organization to a changing environment. Good leadership requires vision and special personality traits such as conviction or resoluteness to enhance the credibility of mission statements and to effective...

Thanks to their name recognition and popularity, celebrities play an important role in American politics. Celebrity endorsements could add to the momentum of a politician’s campaign and win the candidate extensive media coverage. There is one caveat though: the political preference of celebrity followers might differ from that of the celebrity. In this paper we explore that possibility. By care...

A number of research efforts on Twitter have been contributed towards understanding various factors that are related to retweetability, analyzing retweeting and diffusion patterns, predicting retweets, etc. One fundamental research question remains untackled: given a user and her followers, which of the followers are likely to spread her tweets to the world (the information spreader identificat...

This paper proposes a control scheme for distributed sensing using a leader/follower multi-agent architecture. The control objective is to make a group of mobile agents cover and sense a sequence of regions of interest. More specifically, when the leaders reach a new target region, they stop until the followers have performed a sensing task. Furthermore, the followers must be contained inside t...

Twitter, a popular social network, presents great opportunities for on-line machine learning research. However, previous research has focused almost entirely on learning from passively collected data. We study the problem of learning to acquire followers through normative user behavior, as opposed to the mass following policies applied by many bots. We formalize the problem as a contextual band...

We study the performance of leader-follower noisy consensus networks, and in particular, the relationship between this performance and the locations of the leader nodes. Two types of dynamics are considered (1) noise-free leaders, in which leaders dictate the trajectory exactly and followers are subject to external disturbances, and (2) noise-corrupted leaders, in which both leaders and followe...
