Cognitive Characteristics of Expert, Middle of the Pack, and Back of the Pack Ultra-Endurance Triathletes

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.

Vanishing lines in the sand – Why a new map of the Middle East is necessary. CEPS Commentary, 1 October 2013

As the stalemate in Syria drags on, territorial divisions in the country are becoming more entrenched and the civil war is spreading to Syria’s neighbours; aggravating long-standing sectarian divisions in the whole region. In the view of Steven Blockmans, a lasting agreement cannot be reached in the Middle East if world powers stick to infamous 1916 Sykes-Picot Agreement in which France and the UK secretly dealt with what came to be called the ‘Syria Question’. Any way out of the quagmire will require a grand bargain – one that establishes a new order in the whole region and draws borders accordingly.

The crisis in Iraq and the twists and turns of Turkish Middle East policy. OSW Commentary No. 142, 29.07.2014

The spectacular offensive by Islamic radicals in Iraq this June has led the country to the verge of collapse, and is another scene of the deep crisis in the Middle East, in which Turkey is entangled. The immediate consequence of this is a severe crisis of prestige after the kidnapping by terrorists of Turkish diplomats and Ankara’s inability to resolve the situation; in the long term consequences include escalation of the Kurdish problem, and a further increase in threats to the security of Turkey itself as well as the fundamental principles of its foreign policy. Both Ankara’s options and its political will to actively respond to the crisis are extremely limited. Yet again in recent years, the current crisis, the broader situation in the Middle East, and finally the position of Turkey in the region elude unambiguous assessments and forecasts – these are prevented by the scale and growth of the reappraisals and tensions in the region. The only undoubted fact is that Turkey is strategically and irreversibly entangled in the Middle East’s problems, which are an important factor affecting the transformation of the state which the ruling AKP is implementing; and in the near future, this state of affairs will only deepen.

Turkey and the Kurdish problem; new approaches in the face of the Middle East crises. Point of View No. 30, February 2013

From the Introduction. For almost a hundred years (since World War I and the disintegration of the Ottoman Empire) stability – or rather, the permanent threat to stability – has been a key challenge for the Middle East. One of the central elements of this threat has been the so-called Kurdish problem, that is, the issues that continually arise between the states of the region and the Kurdish minority living in the area, as well as the tensions among the individual states caused by a range of issues related to local Kurds. The country most affected by the Kurdish problem is Turkey.

(Table 1) Grain size results, statistical parameters and magnetic susceptibility values of disturbed sediments from ODP holes 204-1249C and 204-1245B

Soupy and mousse-like fabrics are disturbance sedimentary features that result from the dissociation of gas hydrate, a process that releases water. During the core retrieval process, soupy and mousse-like fabrics are produced in the gas hydrate-bearing sediments due to changes in pressure and temperature conditions. Therefore, the identification of soupy and mousse-like fabrics can be used as a proxy for the presence of gas hydrate in addition to other evidence, such as pore water freshening or anomalously cool temperature. We present here grain-size results, mineralogical composition and magnetic susceptibility data of soupy and mousse-like samples from the southern Hydrate Ridge (Cascadia accretionary complex) acquired during Leg 204 of the Ocean Drilling Program. In order to study the relationship between sedimentary texture and the presence of gas hydrates, we have compared these results with the main textural and compositional data available from the same area. Most of the disturbed analyzed samples from the summit and the western flank of southern Hydrate Ridge show a mean grain size coarser than the average mean grain size of the hemipelagic samples from the same area. The depositional features of the sediments are not recognised due to disturbance. However, their granulometric statistical parameters and distribution curves, and magnetic susceptibility logs indicate that they correspond to a turbidite facies. These results suggest that gas hydrates in the southern Hydrate Ridge could form preferentially in coarser grain-size layers that could act as conduits feeding gas from below the BSR. Two samples from the uppermost metres near the seafloor at the summit of the southern Hydrate Ridge show a finer mean grain-size value than the average of hemipelagic samples. They were located where the highest amount of gas hydrates was detected, suggesting that in this area the availability of methane gas was high enough to generate gas hydrates, even within low-permeability layers. The mineralogical composition of the soupy and mousse-like sediments does not show any specific characteristic with respect to the other samples from the southern Hydrate Ridge.

Sedimentology of the Rio Grande Rise area

Surface sediment samples and three gravity cores from the eastern terrace of the Vema Channel, the western flank of the Rio Grande Rise, and the Brazilian continental slope were investigated for physical properties, grain size, and clay mineral composition. Discharge of the Rio Doce is responsible for kaolinite enrichments on the slope south of 20° and at intermediate depths of the Rio Grande Rise. The long-distance advection of kaolinite with North Atlantic Deep Water from lower latitudes is of minor importance as evidenced by low kaolinite/chlorite ratios on the Mid-Atlantic Ridge. Cyclic variations of kaolinite/chlorite ratios in all our cores, with maxima in interglacials, are attributed to low-and high-latitude forcing of paleoclimate on the Brazilian mainland and the related discharge of the Rio Doce. A long-term trend toward more arid and 'glacial' conditions from 1500 ka to present is superimposed on the glacial-interglacial cyclicity.
