A strategy for zooming in and out the topological environment of a node in a complex network is developed. This approach is applied here to generalize the subgraph centrality of nodes in complex networks. In this case the zooming in strategy is based on the use of some known matrix functions which allow focusing locally on the environment of a node. When a zooming out strategy is applied new matrix functions are introduced, which give a more global picture of the topological surrounds of a node. These indices permit a modulation of the scales at which the environment of a node influences its centrality. We apply them to the study of 10 protein-protein interaction (PPI) networks. We illustrate the similarities and differences between the generalized subgraph centrality indices as well as among them and some classical centrality measures. We show here that the use of centrality indices based on the zooming in strategy identifies a larger number of essential proteins in the yeast PPI network than any of the other centrality measures studied.

IDA Reports are reviewed by outside panels of experts to ensure their ht!h quality and relevance to the problems studied, and they are released by the President of IDA. Group ReportsGroup Reports recora the findings and results of IDA established working groups and panels composed of senior individuals addressing major issues which otherwise would be the subject of an IDA Report.

ABSTRACT (Maximum 200 words)This paper sets forth a research-based conceptual framework for understanding and addressing battle staff functioning and its relation to the effectiveness of combat organizations. It also develops a concept for maintaining battle staff structure and function under the heavy stress of combat. Together, the melding of structure and function and the notion of functional competence constitute the area of Battle Staff Integration. This paper offers practitioners (military leaders, trainers, and performance analysts) guidance for developing and directing effective battle staffs. The dynamic structure and functioning of military organizations are discussed and the roles of battle staffs are analyzed. An historical and analytical review of organizational theories and concepts is included, and the concept of team work and the characterislics of effective teams are discussed. A conceptual framework is presented for teamwork in problem-solving and decision-making activities within hierarchical organizations. SUBJECT TERMS PREFACEThis paper had its origin in 1963 in a program of research concerned with highlevel leadership conducted for the U.S. Army Command and General Staff College and of which I was project director. During the course of the research, it became apparent that little was known systematically about the dynamics of large military organizations--about what goes on within a combat unit in terms of the dynamic determinants of its effectiveness on the battlefield. The result was a series of intermittent projects over the last 20 years, conducted whenever i...

“…The relation between the two scales follows a feedback loop with the local (i.e., the individual) dynamics shaping the global (i.e., group) dynamics, and vice-versa [21]. The complex interaction among such dynamics can be the key mechanism of several group phenomena, as the emergence of different communication topologies [22][23][24][25], the structuring of the social identity, the ingroup/out-group effects [26,27], as well as of the social influence processes [28][29][30][31].…”

The modeling of opinion dynamics in social systems has attracted a good deal of attention in the last decade. Even though based on intuition and observation, the mechanisms behind many of these models need solid empirical grounding. In this work, we investigate the relation among subjective variables (such as the personality), the dynamics of the affinity network dynamics, the communication patterns emerging throughout the social interactions and the opinions dynamics in a series of experiments with five small groups of ten people each. In order to ignite the discussion, the polemic topic of animal experimentation was proposed. The groups essentially polarized in two factions with a set of stubborn individuals (those not changing their opinions in time) playing the role of anchors. Our results suggest that the different layers present in the group dynamics (i.e., individual level, group dynamics and meso-communication) are deeply intermingled, specifically the stubbornness effect appears to be related to the dynamical features of the network topologies, and only in an undirected way to the personality of the participants.
