According to Sannikov and Skrzypacz (2007), collusion breaks down in public Nash equilibrium. Here, though, firms collude in public communication equilibrium as long as equation (5) in the paper holds. If it fails, this agreement falls apart for the same reason as in Sannikov and Skrzypacz’s result: obedient firms cannot be identified, so discouraging overproduction requires punishing everyone ...

Current research in automated negotiation is lack of a unified technical standard, which is an obstacle for the system to be applied practically. The existing standard KQML (Knowledge Query Manipulation Language) has obvious flaws in its semantics definition; moreover, its function is insufficient for describing negotiation. The contribution of the work is twofold. On one hand, it expands the s...

We propose an online algorithm for planning under uncertainty in multi-agent settings modeled as DEC-POMDPs. The algorithm helps overcome the high computational complexity of solving such problems off-line. The key challenge is to produce coordinated behavior using little or no communication. When communication is allowed but constrained, the challenge is to produce high value with minimal comm...

There is increasing interest in the storage, retrieval, and analysis of email communications. One active area of research focuses on the inference of properties of the underlying social network giving rise to the email communications[1, 2]. Email communication between individuals implies some type of relationship, whether it is formal, such as a manager-employee relationship, or informal, such ...

Online discussion activities are designed for computer-mediated learning activities in face-to-face, hybrid, and totally online courses. The use of asynchronous computer-mediated communication (A-CMC) coupled with authentic workplace case studies provides students in the protected learning environment with opportunities to practice workplace decision making and communication. In this study, com...

The opportunity for online engagement increases possible exposure to potentially risky behaviors teens, which may have significant negative consequences. Effective family communication about safety can help reduce the adolescent behavior and limit consequences after it occurs. Our paper contributes a theory of factors that positively influence teen parent perception provides design implications...

We consider distributed online learning protocols that control the exchange of information between local learners in a round-based learning scenario. The learning performance of such a protocol is intuitively optimal if approximately the same loss is incurred as in a hypothetical serial setting. If a protocol accomplishes this, it is inherently impossible to achieve a strong communication bound...

Four preservice teachers’ online discussion groups of eight randomly assigned participants each were studied to analyze the contribution of individual and social factors in the development of communication networks. Participants shared observations and followup responses in five weekly rounds of data collection. Using a core-periphery social network analysis model (Borgatti and Everett, 1999), ...

"Active listening" is a well-known ingredient in contexts that involve gathering information and solving problems. Demanding both verbal and nonverbal skills, this way of communication improves mutual understanding by using techniques like paraphrasing. The benefits are manifold and crucial for computer scientists. For instance, it avoids misunderstandings, as people verify they do really under...
