Objectives The purpose of this study was to examine cognitive differences between expert and non-expert UE triathletes. Design Twenty-one UE triathletes were stratified according to finishing times into three groups; experts (<9.5 h), middle of the pack (∼12.5 h), and back of the pack triathletes (>14.0 h). Methods Cognition was examined using a think-aloud protocol with the aid of a video montage of segments from an UE triathlon representing periods of high decision-making or cognition. Inductive qualitative analyses supported the classification of athlete cognitions as passive, active, or proactive. Results Expert triathletes reported a greater emphasis on thoughts related to their performance, while middle of the pack and back of the pack triathletes reported a greater number of passive thoughts. Furthermore, experts were more proactive in their approach to performance situations than mid- and back-pack triathletes. Conclusions Expert UE triathletes are cognitively different from non-experts, although future research is needed to determine the role these differences play in promoting expert performance.

Summary: The ‘Six Pack’ forms part of the economic governance reforms which are being implemented in order to prevent a repeat of the current sovereign debt crisis in the Euro Area. This legislative package involves strengthening the Stability and Growth Pact, with stronger financial sanctions and more focus on debt; a new directive on national budgetary frameworks and a new framework to monitor and correct macroeconomic imbalances. Furthermore, the implementation of the ‘Six Pack’ also involves procedural reforms, in particular reverse majority voting, as well as more oversight by the European Parliament. Inter-institutional negotiations on the ‘Six Pack’ took over a year. In the meantime, the sovereign debt crisis had deepened and broadened, implying that the ‘Six Pack’ may have come ‘too late’. The ‘Six Pack’ has also proved to be ‘too little’ to address the crisis and by the time it entered into force, further measures and proposals to strengthen economic governance had to be made. Nevertheless, the ‘Six Pack’ comprises some positive developments. In particular, recognising that fiscal policy is a matter of national sovereignty, it sets a new approach which relies on institutional reforms at national level. As such, it constitutes a first, small step to improve economic governance in the Euro Area.

During three Antarctic expeditions (2004, ANT XXI-4 and XXII-2; 2006, ANT XXIII-6) with the German research icebreaker R/V Polarstern, six different amphipod species were recorded under the pack ice of the Weddell Sea and the Lazarev Sea. These cruises covered Austral autumn (April), summer (December) and winter (August) situations, respectively. Five of the amphipod species recorded here belong to the family Eusiridae (Eusirus antarcticus, E. laticarpus, E. microps, E. perdentatus and E. tridentatus), while the last belongs to the Lysianassidea, genus Cheirimedon (cf. femoratus). Sampling was performed by a specially designed under-ice trawl in the Lazarev Sea, whereas in the Weddell Sea sampling was done by scuba divers and deployment of baited traps. In the Weddell Sea, individuals of E. antarcticus and E. tridentatus were repeatedly observed in situ during under-ice dives, and single individuals were even found in the infiltration layer. Also in aquarium observations, individuals of E. antarcticus and E. tridentatus attached themselves readily to sea ice. Feeding experiments on E. antarcticus and E. tridentatus indicated a carnivorous diet. Individuals of the Lysianassoid Cheirimedon were only collected in baited traps there. Repeated conventional zooplankton hauls performed in parallel to this study did not record any of these amphipods from the water column. In the Lazarev Sea, E. microps, E. perdentatus and E. laticarpus were regularly found in under-ice trawls. We discuss the origin and possible sympagic life style of these amphipods.

Different parameterizations of subgrid-scale fluxes are utilized in a nonhydrostatic and anelastic mesoscale model to study their influence on simulated Arctic cold air outbreaks. A local closure, a profile closure and two nonlocal closure schemes are applied, including an improved scheme, which is based on other nonlocal closures. It accounts for continuous subgrid-scale fluxes at the top of the surface layer and a continuous Prandtl number with respect to stratification. In the limit of neutral stratification the improved scheme gives eddy diffusivities similar to other parameterizations, whereas for strong unstable stratifications they become much larger and thus turbulent transports are more efficient. It is shown by comparison of model results with observations that the application of simple nonlocal closure schemes results in a more realistic simulation of a convective boundary layer than that of a local or a profile closure scheme. Improvements are due to the nonlocal formulation of the eddy diffusivities and to the inclusion of heat transport, which is independent of local gradients (countergradient transport).
