Prior theory suggests that reputation spreading (e.g., gossip) and punishment are two key mechanisms to promote cooperation in groups, but no behavioral research has yet examined their relative effectiveness and efficiency in promoting and maintaining cooperation. To examine these issues, we observed participants interacting in a four-round public goods game (PGG) with or without gossip and pun...

Determining the network size is a critical process in numerous areas (e.g., computer science, logistic, epidemiology, social networking services, mathematical modeling, demography, etc.). However, many modern real-world systems are so extensive that measuring their poses serious challenge. Therefore, algorithms for determining/estimating this parameter an effective manner have been gaining popu...

Information Communication Technology (ICT) contributes effectively to spreading of all sorts of information, including gossip and rumors. The continuous growth of online communications calls thus for analysis of their mechanisms and consequences, as moral responsibility increases with increasing information. Taking the Information Ethics (IE) perspective we discuss gossip and its role in social...

Global is an optimization algorithm conceived in the ’80s. Since then several papers discussed improvements of algorithm, but adapting it to a multi-thread execution environment only recent branch development [1]. Our previous work focused on parallel implementation single machine sometimes use distributed systems inevitable. In this paper we introduce new version which first step towards fully...

Gossip-based information dissemination protocols are considered easy to deploy, scalable and resilient to network dynamics. Loadbalancing is inherent in these protocols as the dissemination work is evenly spread among all nodes. Yet, large-scale distributed systems are usually heterogeneous with respect to network capabilities such as bandwidth. In practice, a blind load-balancing strategy migh...

Gossip in the workplace has generally been ignored by researchers and often criticized by practitioners. The authors apply a transdisciplinary evolutionary approach to argue that gossip is a natural part of social organizations and that certain conditions can encourage socially-redeeming gossip. They draw on case studies involving cattle ranchers, members of a competitive rowing team, and airli...

P2P networks are becoming increasingly used for wide-scale collaborative information spreading over the Internet. Thus, the ability to share information with large group of network nodes at near-optimal cost may be the one step that will allow P2P networks to replace traditional broadcast. For large groups, there are substantial inefficiencies that result from using deterministic tree-based app...

The gossip mechanism could support reliable and scalable communication in large-scale settings. In large-scale peer-to-peer environment, however, each node could only have partial knowledge of the group membership. More seriously, because the node has no global knowledge about the underlying topology, gossip mechanism incurs much unnecessary network overhead on the Internet. In this paper, we p...

Gossip is a subject that has been studied by researchers from an array of disciplines with various foci and methods. We measured the content of language use by members of a competitive sports team across 18 months, integrating qualitative ethnographic methods with quantitative sampling and analysis. We hypothesized that the use of gossip will vary significantly depending on whether it is used f...

College students ranked the interest value of 12 different gossip scenarios; likelihood of spreading the gossip; and the people to whom they would be most likely to tell the gossip, depending on whether the gossip was about male or female professors, relatives, friends, acquaintances, strangers, or a same-sex rival or a romantic partner. Damaging, negative news about rivals and positive news ab...
