Terrorism as Collective Communication: The Collective Communication Model of Terrorism (CCMT)

Social and Personality Psychology Compass, 2010
Abstract This paper proposes that the psychological and behavioral effects of terrorist threat can be understood as a collective communication process that occurs between terrorists and their potential victims. Based on classic communication theory, terrorists are regarded as the senders

Optimization of Collective Communications in HeteroMPI

2007
HeteroMPI is an extension of MPI designed for high performance computing on heterogeneous networks of computers. The recent new feature of HeteroMPI is the optimized version of collective communications. The optimization is based on a novel performance communication model of switch-based computational clusters.

Optimizing Collective Communication in UPC

2014 IEEE International Parallel & Distributed Processing Symposium Workshops, 2014
Message Passing Interface (MPI) has been the defacto programming model for scientific parallel applications. However, data driven applications with irregular communication patterns are harder to implement using MPI. The Partitioned Global Address Space (PGAS) programming models present an alternative approach to improve programmability.

A framework for collective personalized communication

Proceedings International Parallel and Distributed Processing Symposium, 2004
The paper explores collective personalized communication. For example, in all-to-all personalized communication (AAPC), each processor sends a distinct message to every other processor. However, for many applications, the collective communication pattern is many-to-many, where each processor sends a distinct message to a subset of processors.

Harp: Collective Communication on Hadoop

2015 IEEE International Conference on Cloud Engineering, 2015
Big data processing tools have evolved rapidly in recent years. MapReduce has proven very successful but is not optimized for many important analytics, especially those involving iteration. In this regard, Iterative MapReduce frameworks improve performance of MapReduce job chains through caching. Further, Pregel, Giraph and Graph Lab abstract data as a

Collective sorting with local communication

2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005
This paper describes an experimental study of the problem of collective sorting, in which multiple robots under simple reactive control rearrange initially randomly distributed objects of different classes into separate clusters so that each cluster contains objects of only one class.

Communities, Collectivities, and the Ethics of Research

Canadian Journal of Community Mental Health, 1998
Ethical concerns have always placed limits on research, but the spirit of the times has led to an expansion of the territory covered by ethics. This new approach is found in the code of ethics presently in final revision by the three major granting agencies. This code will give unprecedented power to “collectivities” in the research process.

Collective efficacy as a measure of community

Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2005
As human-computer interaction increasingly focuses on mediated interactions among groups of individuals, there is a need to develop techniques for measurement and analysis of groups that have been scoped at the level of the group. Bandura's construct of perceived self-efficacy has been used to understand individual behavior as a function of domain ...

Communication Collective: An Adaptive Multiagent Communication Platform

2019 Winter Simulation Conference (WSC), 2019
A robust, consistent and high-capacity data network is critical in modern society to ensure that governments, businesses and individuals are able to communicate and coordinate disaster relief, just in time deliveries, or to organize how and where to meet friends. Existing terrestrial communication networks are susceptible to being disabled or destroyed
