Fiscal Austerity

British universities are experiencing a climate of fiscal austerity including severe budget cuts coupled with intensifying competition for markets have seen the emergence of audit culture which afflicts the public sector in general. This entails the risk to the integrity of university culture disappearing. This paper seeks to explore the interconnections between developing trends in universities which cause processes likely to undermine the objectivity and independence of research. We question that universities’ alignment with the capitalist business sector and the dominant market economy culture. Despite arguably positive aspects, there is a danger that universities may be dominated by hegemonic sectional interest rather than narratives of openness and democratically oriented critique. We also argue that audit culture embedded in reputation management, quality control and ranking hierarchies may necessarily promote deception while diminishing a collegiate culture of trust and pursuit of truth which is replaced by destructive impersonal accountability procedures. Such transitions inevitably contain insidious implications for the nature of the academy and undermine the values of academic-intellectual life.

Multi Agent

Multi-agent distributed systems are characterized by autonomous entities that interact with each other to provide, and/or request, different kinds of services. In several contexts, especially when a reward is offered according to the quality of service, individual agents (or coordinated groups) may act in a selfish way. To prevent such behaviours, distributed Reputation Management Systems (RMSs) provide every agent with the capability of computing the reputation of the others according to direct past interactions, as well as indirect opinions reported by their neighbourhood. This last point introduces a weakness on gossiped information that makes RMSs vulnerable to malicious agents’ intent on disseminating false reputation values. Given the variety of application scenarios in which RMSs can be adopted, as well as the multitude of behaviours that agents can implement, designers need RMS evaluation tools that allow them to predict the robustness of the system to security attacks, before its actual deployment. To this aim, we present a simulation software for the vulnerability evaluation of RMSs and illustrate three case studies in which this tool was effectively used to model and assess state-of-the-art RMSs.
