Drill cores from the inner-alpine valley terrace of Unterangerberg, located in the Eastern Alps of Austria, offer first insights into a Pleistocene sedimentary record that was not accessible so far. The succession comprises diamict, gravel, sand, lignite and thick, fine grained sediments. Additionally, cataclastic deposits originating from two paleo-landslide events are present. Multi-proxy analyses including sedimentological and palynological investigations as well as radiocarbon and luminescence data record the onset of the last glacial period (Wurmian) at Unterangerberg at similar to 120-110 ka. This first time period, correlated to the MIS 5d, was characterised by strong fluvial aggradation under cold climatic conditions, with only sparse vegetation cover. Furthermore, two large and quasi-synchronous landslide events occurred during this time interval. No record of the first Early Wiirmian interstadial (MIS 5c) is preserved. During the second Early Wiirmian interstadial (MIS 5a), the local vegetation was characterised by a boreal forest dominated by Picea, with few thermophilous elements. The subsequent collapse of the vegetation is recorded by sediments dated to similar to 70-60 ka (i.e. MIS 4), with very low pollen concentrations and the potential presence of permafrost. Climatic conditions improved again between similar to 55 and 45 ka (MIS 3) and cold-adapted trees re-appeared during interstadials, forming an open forest vegetation. MIS 3 stadials were shorter and less severe than the MIS 4 at Unterangerberg, and vegetation during these cold phases was mainly composed of shrubs, herbs and grasses, similar to what is known from today's alpine timberline. The Unterangerberg record ended at similar to 45 ka and/or was truncated by ice during the Last Glacial Maximum. (C) 2013 Elsevier Ltd. All rights reserved.

Climate model projections suggestwidespread drying in the Mediterranean Basin and wetting in Fennoscandia in the coming decades largely as a consequence of greenhouse gas forcing of climate. To place these and other “Old World” climate projections into historical perspective based on more complete estimates of natural hydroclimatic variability, we have developed the “Old World Drought Atlas” (OWDA), a set of year-to-year maps of tree-ring reconstructed summer wetness and dryness over Europe and the Mediterranean Basin during the Common Era.
The OWDA matches historical accounts of severe drought and wetness with a spatial completeness not previously available. In addition, megadroughts reconstructed over north-central Europe in the 11th and mid-15th centuries
reinforce other evidence from North America and Asia that droughts were more severe, extensive, and prolonged over Northern Hemisphere land areas before the 20th century, with an inadequate understanding of their causes. The OWDA provides new data to determine the causes of Old World drought and wetness and attribute past climate variability to forced and/or internal variability.

The Jewish community in Shanghai was among the first to settle in the Treaty Ports which were opened after the Opium war. Jewish population grew until the rendition of the foreign settlements to the Chinese authorities, and its history broadly consists of three periods.The first Jews came to Shanghai in the XIX century were sephardits from Iraq and India. Among those emigrated to Shanghai following the expansion of the British commerce in China were such famous families as Sassoons, Hardoons and Kadoories.The second wave arrived with the White Russians exodus after the October Revolution; they were askanzits Jews who fled from pogroms and the Russian civil war. The third wave were Jews fleeing from central Europe in the 1930s. This group was the largest of the three.The first settlers saw Shanghai as a port of opportunities, while the others came there seeking refuge.The interwar Shanghai could offer protection and a temporary place of residence for Jewish people. In the 1920s and 1930s Jews coming to Shanghai were helped by local Jewish associations, which supported them in the search for accommodations and jobs. This net of associations was effective until WWII. The war, however, made them face increasing number of contraints. In this constrained situation we should remember that the Japanese authorities, occupying the International Settlement, imposed a ban for new Jewish arrivals to settle in the Hongkou district; while the French authorities under the Vichy government imposed a complete ban on Jewish residents in their concession. Finally, the Jewish immigration to Shanghai had stopped completely in 1942, because there were no more ways to get there.Japanese authorities, however, were not interested in applying the racial laws as their priority lay in the conquest of China. And although the Jews were in an enemy's territory, they were not persecuted. In fact, when the war was over they left Shanghai directly to the United States and Israel.

Existing studies of European Union (EU) enlargement provide few answers to questions concerning continuity and change in the dynamics of the process. This article identifies a number of conditioning factors that have shaped the EU’s approach to eastern enlargement and traces elements of continuity and change in the EU’s handling of Turkey’s membership aspirations. The article focuses on three established factors – member state preferences, supranational activism and EU capacity – and two less prominent factors – public opinion and narrative frame
