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.

Distributed joint congestion control and routing optimization has received a significant amount of attention recently. To date, however, most of the existing schemes follow a key idea called the back-pressure algorithm. Despite having many salient features, the first-order sub gradient nature of the back-pressure based schemes results in slow convergence and poor delay performance. To overcome these limitations, the present study was made as first attempt at developing a second-order joint congestion control and routing optimization framework that offers utility-optimality, queue-stability, fast convergence, and low delay.  Contributions in this project are three-fold. The present study propose a new second-order joint congestion control and routing framework based on a primal-dual interior-point approach and established utility-optimality and queue-stability of the proposed second-order method. The results of present study showed that how to implement the proposed second-order method in a distributed fashion.
