Studies in human and non-human primates indicate that basic socio-cognitive operations are inherently linked to the power of gaze in capturing reflexively the attention of an observer. Although monkey studies indicate that the automatic tendency to follow the gaze of a conspecific is modulated by the leader-follower social status, evidence for such effects in humans is meager. Here, we used a g...

Human groups are unusual among primates in that our leaders are often democratically selected. Faces affect hiring decisions and could influence voting behavior. Here, we show that facial appearance has important effects on choice of leader. We show that differences in facial shape alone between candidates can predict who wins or loses in an election (Study 1) and that changing context from war...

Meetings are not always perceived as beneficial by employees. However, meetings are important for followers to execute their tasks because they provide a context in which information and other resources can be shared. This research examines whether meeting effectiveness can be explained by the leader behavior that is displayed. Leadership behaviors are studied because leaders often facilitate m...

In this paper, we propose methods and experiment with Flickr network to solve two problems. First, we study how the community in a social network evolves over time. We then report our findings about community evolution and new node behavior in the Flickr network. Second, we define the leader group of a network and propose novel mothods to measure the evolution of leader group. We then propose a...

This article attends to a broad range of practically significant employee motivations and provides insight into how to enhance individual-level performance by examining individual-level state goal orientation emergence in organizational work groups. Leadership and multilevel climate processes are theorized to parallel each dimension of state goal orientation to cue and ultimately induce the cor...

A multi-robot formation composed of autonomous agents may need to maintain an overall rigid shape for tasks such as collective transport of an object. To distribute control, we construct leader-follow formations in the plane that are persistent: designated “leader” robots control the movement of the entire formation, while the remaining “follower” robots maintain directed local links sensing da...

Purpose This study investigated the behaviors of leaders across economically-distressed regions within four countries (Ethiopia, India, Pakistan, Philippines), whether the impact of their behavior would be differentially affected by culture, and the psychometric properties of the Leadership Practices Inventory (LPI) in this setting. Design Health care leaders and their constituents were surveye...

This paper is concerned with the characterization of optimal strategies for a service firm acting in an oligopolistic environment. The decision problem is formulated as a leader-follower game played on a transportation network, where the leader firm selects a revenue-maximizing price schedule that takes explicitly into account the rational behavior of the customers. In the context of our analys...

We introduce and summarize the researches that are categorized into parts on Twitter studied for the past five years. The circulators in Twitter can be divided into two types, mass media source and evangelist, except normal users. If a certain leader has a huge number of retweets, he/she may be seen as an influential leader. The less difference between the number of ‘following’ and ‘follower’ a...

When adopted, wildlife protection policies in Canadian forests typically cover large areas and affect multiple economic agents working these landscapes. Such measures are likely to increase the costs of timber for forestry companies operating area, which may hinder their acceptance unless harvesting remains profitable. We propose a bi-level problem that accounts profit-maximizing behavior an ar...
