Last glacial loess dynamics in the Southern Caucasus (NE-Armenia) and the phenomenon of missing loess deposition during MIS-2Wolf, Daniel, Lomax, Johanna, Sahakyan, Lilit, Hovakimyan, Hayk, Profe, Jörn, Schulte, Philipp, Suchodoletz, Hans von, Richter, Christiane, Hambach, Ulrich, Fuchs, Markus, Faust, Dominik 22 April 2024 (has links)
The Marine Isotope Stage (MIS) 2 is considered the coldest, driest and stormiest period during the last Glacial-Interglacial cycle in large parts of Eurasia. This resulted from strongly decreased northern hemisphere temperature and related maximum extension of northern ice sheets that strongly reinforced large-scale circulation modes such as westerlies and East Asian Winter Monsoon driven by the Siberian High. Normally, this intensified circulation is reflected by maximum loess deposition in numerous loess regions spanning Europe and Asia. However, here we present a new loess record from the Caucasus region in NE-Armenia providing evidence in support of heavily reduced or even lacking loess formation during the MIS-2. Owing to implementations of comprehensible luminescence dating work and a provenance survey using rock magnetic and geochemical data, we are able to define distinct loess formation phases and to retrace sediment transport pathways. By comparing our results to other Eurasian palaeo-records, we unveil general atmospheric circulation modes that are most likely responsible for loess formation in the Southern Caucasus. Moreover, we try to test different scenarios to explain lacking loess formation during MIS-2. In line with other archive information, we suggest that loess formation was hampered by higher regional moisture conditions caused by a southward-shift of westerlies and renewed moisture absorption over the Black Sea. Our results show that modifications of MIS-2 circulation modes induced a very heterogeneous moisture distribution, particularly in the lower mid-latitudes of Eurasia producing a juxtaposition of very dry (morphodynamically active) and moderately dry (morphodynamically stable) areas.

An analysis of Soviet Jewish emigration in the 1970sSalitan, Laurie P. January 1992 (has links)
Domestic, not foreign affairs drove Soviet policy on Jewish emigration during the period of 1968-1989. This study challenges the prevailing view that fluctuating levels of exit from the USSR were correlated to the climate of relations between the USA and the USSR. The analysis also considers Soviet-German emigration for comparative perspective. Extensive historical background, with special emphasis on Soviet nationality policy is provided.

The Socio-political Phenomenon of Qazaqlïq in the Eurasian Steppe and the Formation of the QazaqsLee, Joo Yup 08 August 2013 (has links)
This dissertation is concerned with the formation of the Qazaqs in the context of the custom of political vagabondage known as qazaqlïq in post-Mongol Central Eurasia. More specifically, my study addressed the process whereby the Uzbek nomads inhabiting the eastern Dasht-i Qipchāq bifurcated into the Qazaqs and the Shibanid Uzbeks in the sixteenth century in consequence of the qazaqlïq activities led by two rival Chinggisid families: the Urusids and the Abū al-Khairids.
Qazaqlïq, or the qazaq way of life, was a form of political vagabondage that involved escaping from one’s state or tribe, usually from a difficult social or political situation, and living the life of a freebooter in a frontier or other remote region. The custom of political vagabondage was by no means an exclusively post-Mongol Central Eurasian phenomenon. It existed in other places and at other times. However, it was in post-Mongol Central Eurasia that it became a widespread socio-political phenomenon that it came to be perceived by contemporaries as a custom to which they attached the specific term, qazaqlïq.
During the post-Mongol period, the qazaq way of life developed into a well-established political custom whereby political fugitives, produced by the internecine struggles within the Chinggisid states, customarily fled to frontier or other remote regions and became freebooters, who came to be called qazaqs. Such Chinggisid and Timurid leaders as Muḥammad Shībānī and Temür became qazaqs before coming to power.
The Qazaqs came into being as a result of the qazaqlïq activities of Jānībeg and Girāy, two great-grandsons of Urus Khan (r. ca. 1368–78), and of Muḥammad Shībānī, the grandson of Abū al-Khair Khan (r. ca. 1450–70) that resulted in the division of the Uzbek Ulus into the Qazaqs and the Shibanid Uzbeks in the sixteenth century.
The Tatar and Slavic cossacks (Russian kazak, Ukrainian kozak) who appeared in the Black Sea steppe in the fifteenth and sixteenth centuries were the products of the qazaqlïq, or cossack phenomenon. Significantly, Ukrainian cossackdom led to the formation of the Ukrainian Hetmanate, which eventually contributed to the consolidation of a separate Ukrainian identity.

Geopolitická příslušnost Ruska v současném ruském diskurzu / Geopolitical affiliation of Russia in contemporary Russian discourseKalinová, Olga January 2012 (has links)
The question of Russia's geopolitical affiliation has been a cause of centuries long debate, whether Russia belongs to Europe or to Asia. From the geographical point of view, Russia is predominantly situated in Asia. From cultural and civilisational points of view, Russian people tend to lean towards Europe, even though they capture elements of both civilizations. By examination of the most prominent Russian schools of thought, mainly of geopolitical nature (Slavophilism, Westernism, Atlantisms, Eurasianism, etc.) the work seeks to systemize the answers to this question. At the same time, it seeks to determine through analysis of the contemporary Russian foreign policy, which of these ideological leanings plays a dominant role in foreign policy discourse in Russia since 2000. Thanks to identification of this priority direction and by determining the primary orientation of Russian foreign policy in a particular region, the aim of this work is finally to answer the following question: What is Russia: Europe, Asia, or a separate continent of Eurasia?

Meta-Geopolitics of Central Asia : A Comparative Study of the Regional Influence of the European Union and the Shanghai Co-operation OrganizationAghaie Joobani, Hossein January 2013 (has links)
Central Asia has been the focal point of intense geopolitical power struggle throughout history. At the dawn of the 21st century, Central Asia has undergone major changes as the European Union and the China-led Shanghai Co-operation Organization have emerged as two normative powers, both seeking to influence the patterns of security governance in the region. This study aims to delve deep into ‘the black boxes’ of the EU’s and China’s foreign policies toward five CA republics. It starts from the premise that the bulk of research on Eurasian politics tend to concentrate mostly on realist and traditional geopolitical doctrine, which seem to have failed to properly explain the normative and ideational transformations that have taken place in the region as a result of the presence of these two emerging normative agents. By interweaving both realist and constructivist theories of International Relations (IR) into a new all-encompassing analytical framework, termed “meta-geopolitics”, the thesis seeks to trace and examine how geopolitical as well as normative components of the EU and Chinese regional strategies have affected the contemporary power dynamics in the post-Soviet space. I argue that, in contrast to the geopolitical struggle during the 19th and 20th centuries, a clash of normative powers is brewing in the region between China, under the aegis of the SCO, and the EU. The research also concludes that China has relatively been in a better position in comparison to the EU to render its policies as feasible, effective and legitimate to the Central Asian states.
