Governance can be understood as the system by which actors in society are directed and controlled. Given the trinity "Institution, Market and Organization"a pressing question is: which governance structure minimizes the transaction costs in governing and controlling in the build and service design for organizations similar to a city? We...

Exploiting Graph Properties for Decentralized Reputation Systems

In online communities, users frequently interact with strangers in order to buy and sell products, watch videos, educating themselves, and playing games. Establishing trust among strangers is essential for the functionality of these communities but challenging, as well. Online reputation systems effectively establish trust among strangers by...

Obligations to enforce prohibitions: On the adequacy of security policies

However, it is often unclear what the purpose of such obligations is, and how these can be integrated in the operational processes of the organisation. This can result in policies that may be either too strong or too weak, leading to unnecessary...

Graphs with given diameter maximizing the algebraic connectivity

We propose a class of graphs G?D(n1, n2, ..., nD+1), containing of a chain of D+1 cliques Kn1 , Kn2 , ..., KnD+1, where neighboring cliques are fully-interconnected. The class of graphs has diameter D and size N = ? 1?i?D+1ni. We prove that this class of graphs can achieve the maximal number of links, the minimum average hopcount, and more...
