Entry characteristics and academic performance of students in a master of pharmacy degree program in the United Kingdom

Objective. Evaluate the characteristics of a cohort of Master of Pharmacy (MPharm) students upon entry and examine any associations between entry qualifications, type of school attended, socioeconomic deprivation, age and academic performance in the MPharm programme. Methods. A retrospective cohort analysis of data recorded on Aston University’s central database for each individual exiting the MPharm programme during the five year period 2005-6 – 2009-10 (n=644). Results. Entrants were disproportionately drawn from socioeconomically deprived areas and independent (private) schools. Achievement prior to admission was related to the type of school attended but not to deprivation. Performance on the programme was not related to type of school or deprivation but was strongly correlated with prior achievements. Conclusions. Prior achievement is the most important predictor of performance on the MPharm programme but the superior prior achievement of independent school pupils is not seen at the point of graduation. This may have implications for admissions policies.

Message-passing algorithms for optimal utilization of cognitive radio networks

Cognitive Radio has been proposed as a key technology to significantly improve spectrum usage in wireless networks by enabling unlicensed users to access unused resource. We present new algorithms that are needed for the implementation of opportunistic scheduling policies that maximize the throughput utilization of resources by secondary users, under maximum interference constraints imposed by existing primary users. Our approach is based on the Belief Propagation (BP) algorithm, which is advantageous due to its simplicity and potential for distributed implementation. We examine convergence properties and evaluate the performance of the proposed BP algorithms via simulations and demonstrate that the results compare favorably with a benchmark greedy strategy. © 2013 IEEE.
