Self-sacrificing behavior of the leader and the extent to which the leader is representative of the group (i.e., group prototypical) are proposed to interact to influence leadership effectiveness. The authors expected self-sacrificing leaders to be considered more effective and to be able to push subordinates to a higher performance level than non-self-sacrificing leaders, and these effects wer...

Pedestrian following is a common behavior, and may provide a key link between individual locomotion and crowd dynamics. Here, we present a model for following that is motivated by cognitive science and grounded in empirical data. In Experiment 1, we collected data from leader-follower pairs, and showed that a simple speed-matching model is sufficient to account for behavior. In Experiment 2, we...

The purpose of this paper is to focus first on the literature that links leadership to employee wellbeing within the field of organizational behavior, and then turn the attention to a survey on healthcare professionals’ perceptions of the leadership style in three Italian hospitals. The classification of leader behavior is based on the sharing of decision making between leader and follower in t...

In this paper, we used a two-phase exploratory sequential design consisting of qualitative and quantitative research methods and analysis to assess leadership coaching as a leader and leadership development practice. First, we addressed the need for appropriate outcome variables for leadership coaching. Analysis of a focus group study combined with a review of theory resulted in hypotheses link...

RNA secondary structure analysis was performed to understand the translation function of the adenovirus tripartite leader, a 200-nucleotide 5' noncoding region found on all late viral mRNAs. The tripartite leader facilitates the translation of viral mRNAs at late but not early times after infection and eliminates the normal requirement for the eukaryotic initiation factor 4F or cap binding prot...

This thesis develops a hybrid decentralized formation control framework to coordinate multiple mobile robots with nonholonomic constraints. The proposed approach deploys a control theoretic bottom-up approach where, some low level behavior based controllers are coordinated by a discrete event system with supervisory control. The robots are required to navigate in an unstructured environment wit...

This study tested the recent path-goal leadership theory prediction [House, R.J., 1996. Path-goal theory of leadership: Lessons, legacy, and a reformulated theory. The Leadership Quarterly, 7, 323–352] that leader contingent reward behavior negatively moderates relationships between transformational leadership and subordinate performance and job satisfaction at the individual level of analysis....

Voluntary behaviors (i.e., knowledge contribution and word of mouth) are important to the sustainability and growth of online knowledge communities. Although previous studies have identified various factors leading to knowledge contribution and related behaviors, the underlying psychological processes have rarely been examined. In particular, previous studies have not examined how characteristi...

Ad hoc networks are characterized by high dynamics in particular with respect to the formation of network partitions. This behavior makes it difficult to (s)elect a suitable leader for a given network partition at any given time. However, such leaders or representatives are needed by many protocols for ad hoc networks. In this paper, we will illustrate the leader election process and its influe...
