Article history: Received 24 October 2016 Revised 10 January 2017 Accepted 28 February 2017 Available online xxxx Bounded generalized reciprocity (BGR) predicts that people cooperate to maintain a positive reputation with ingroup, but not outgroup, members—and this explains ingroup favoritism in cooperation. We propose that the benefits of maintaining a positive reputation are not limited by gr...

Human-agent interaction for learning with instruction can be viewed on a continuum of instructor/agent control. At one extreme are systems that learn by instructor-driven interactions, such as learning by demonstration, examples, or imitation. The other extreme of the continuum is occupied by systems where instructor interaction is limited to responding to the questions posed by the agent or to...

Reputation systems provide mechanisms through which multiple parties can quantify the trust between one another. These systems seek to generate an accurate assessment in the face of unprecedented community size, while providing anonymity and resilience to malicious attacks. We focus on attacks and defense mechanisms in reputation systems. We present an analysis framework that allows for general...

Many combinations of numbers had mystical implications in ancient times, prompting many mathematicians and historians to believe that the ancients often embraced intricacy for its own sake [...]

Reputation concerns may help to achieve efficiency in cases where imperfect information impedes it. In this paper I highlight the endogenous property of reputation and analyze how it undermines the effectiveness of reputation to achieve efficiency. More reputation implies the possibility of undertaking more activity. At the same time, more activity generates more signals under which reputation ...

Several reputation systems have been proposed for mobile ad-hoc networks in order to stimulate cooperation among mobile nodes. However, whether or not the mobile nodes will agree on the reputation of other nodes is not studied. In this paper, we present a formal specification and analysis of a general class of mechanisms to locally update the reputation of mobile nodes. Given an initial assessm...

In this paper the author discusses how the secret of life was taken care of by our ancients. The contribution of modern research scholars in this fields are also summed up here.

The outcomes of conflicts in many human societies generate reputation effects that influence the nature of later conflicts. Those willing to escalate over even trivial offenses are considered honorable whereas those who do not are considered dishonorable (Nisbett & Cohen, 1996). Here I extend Maynard Smith's hawk-dove model of animal conflict to explore the logic of a strategy which uses reputa...
