Learner-Teacher Interaction (LTI): engaging and supporting students in achieving self-regulated learning

This report represents the second stage of a study which was part of a wide-ranging research programme conducted by the Centre for Excellence of Interprofessional Education, Queen’s University Belfast. The study was an investigation into learner-teacher interaction in the education of undergraduate medical and other healthcare students in order to inform how teachers might facilitate learning in a healthcare setting. It focused in particular on clinical and ward-based tutorials and seminars.

In order to give meaning to this second stage of the study, the report will contextualise the learner-teacher interaction study, will describe the research methods and methods of analysis developed and used to explore learner-teacher interaction. It will then focus on this second stage of the research and the results of the analysis of video sessions of clinical and ward-based tutorials and seminars. In particular it will identify examples of good practice and missed opportunities for the engagement of the learners.

Decentralised formation control and stability analysis for cooperative multi-vehicle manoeuvre

Multi-vehicle cooperative formation control problem is an important and typical topic of research on multi-agent system. This paper presents a formation stability conjecture to conceive a new methodology for solving the decentralised multi-vehicle formation control problem. It employs the “extension-decomposition-aggregation” scheme to transform the complex multi-agent control problem into a group of sub-problems which is able to be solved conveniently. Based on this methodology, it is proved that if all the individual augmented subsystems can be stabilised by using any approach, the overall formation system is not only asymptotically but also exponentially stable in the sense of Lyapunov within a neighbourhood of the desired formation. Simulation study on 6-DOF aerial vehicles (Aerosonde UAVs) has been performed to verify the achieved formation stability result. The proposed multi-vehicle formation control strategy can be conveniently extended to other cooperative control problems of multi-agent systems.

Raiffeisenism abroad: why did German cooperative banking fail in Ireland but prosper in the Netherlands?

Why did imitations of Raiffeisen’s rural cooperative savings and loans associations work well in some European countries, but fail in others? This article considers the example of Raiffeisenism in Ireland and in the Netherlands. Raiffeisen banks arrived in both places at the same time, but had drastically different fates. In Ireland they were almost wiped out by the early 1920s, while in the Netherlands they proved to be a long-lasting institutional transplant. Raiffeisen banks were successful in the Netherlands because they operated in niche markets with few competitors, while rural financial markets in Ireland were unsegmented and populated by long- established incumbents, leaving little room for new players, whatever their institu- tional advantages. Dutch Raiffeisen banks were largely self-financing, closely integrated into the wider rural economy, and able to take advantage of economic and religious divisions in rural society. Their Irish counterparts were not.
