Abstract Significant climatic changes over northern Eurasia during the twentieth century are revealed in numerous variables including those affecting and characterizing the state of the cryosphere. In addition to commonly used in situ observations of snow cover such as snow depth and snow courses, synoptic archives in the former Soviet Union contain regular daily and semidaily reports about the state of the ground in the area surrounding the station. Information about frozen, dry, wet, ponded, and snow-covered land, and in the case of snow-covered land, about the characteristics of snow cover, is available in these reports. A new Global Synoptic Data Network (GSDN) consisting of 2100 stations within the boundaries of the former Soviet Union created jointly by the National Climatic Data Center (NCDC) and Russian Institute for Hydrometeorological Information (RIHMI) was used to assess the climatology of snow cover, frozen and unfrozen ground reports, and their temporal variability for the period from 1936 to 2004. Comparison with satellite measurements of snow cover extent is also presented. During the second half of the twentieth century and over many regions in northern Eurasia, an increase in unfrozen ground conditions (5 days since 1956 over the Russian Federation) was observed. The most prominent changes occurred in the spring season in Siberia and the Far East north of 55°N during April and May by 3 to 5 days, which constitute a 15%–35% change in these regions compared to long-term mean values. Since the beginning of the dataset, surface temperature changes in high latitudes have not been monotonic. As a result, linear trend analyses applied to the entire period of observations can lead to paradoxical conclusions. Specifically, changes in snow cover extent during the 1936–2004 period cannot be linked with “warming” (particularly with the Arctic warming) because in this particular period the Arctic warming was absent.

AbstractHistorical snow-depth observations in the former Soviet Union (FSU) during the period September 1960–August 1984 have been analyzed in order to understand the seasonal cycle of snow coverage in the FSU. Snow cover first appears in September in northeastern regions, and spreads over the entire territory before early January. Snowmelt begins in mid-January in the southern regions and then snow cover retreats rapidly northward until it disappears completely before late June. Northward of 60°N, the land surface is snow-covered for more than half the year. The longest snow-cover duration is observed on the central Siberian plateau (about 9.5 months) and along the Arctic coastal regions (about 8.5 months). One of the most conspicuous features of the snow coverage in the FSU is that the length of the snow-accumulation period differs considerably from region to region (2–7 months), while the length of the snowmelt period is rather short and uniform over almost the entire territory (1–2 months). Although the maximum snow depths are 20–50 cm in most regions of the FSU, they exceed 80 cm in the mountainous regions in central Siberia, Kamchatka peninsula, and along theYenisei river valley. Values for the maximum snow depth are very small along the Lena river valley in spite of the air temperature being extremely low in winter. By calculating correlation coefficients between the snowfall intensities and the sea-level pressures or 500 hPa heights, it is shown that deep snow along the Yenisei river valley is caused by frequent migration of synoptic disturbances from the Arctic Ocean. Snowfalls along the Lena river valley are also caused by traveling disturbances from the Arctic Ocean. Snow accumulation is suppressed after the Arctic Ocean has been frozen.

At the end of the twentieth century, questions of a secondary nature suddenly became topical: what do we remember and who owns the memory? Memory as one of the mental characteristics of an individual’s activity is complemented by the concept of collective memory, which requires a different method of analysis than the activity of a separate individual. In the 1970s, a situation arose that gave rise to the so-called "historical politics" or "memory politics." If philosophical studies of memory problems of the 30’s and 40’s of the twentieth century were focused mainly on the peculiarities of perception of the past in the individual and collective consciousness and did not go beyond scientific discussions, then half a century later the situation has changed dramatically. The problem of memory has found its political sound: historians and sociologists, politicians and representatives of the media have entered the discourse on memory. Modern society, including all social, ethnic and family groups, has undergone a profound change in the traditional attitude towards the past, which has been associated with changes in the structure of government. In connection with the discrediting of the Soviet Union, the rapid decline of the Communist Party and its ideology, there was a collapse of Marxism, which provided for a certain model of time and history. The end of the revolutionary idea, a powerful vector that indicated the direction of historical time into the future, inevitably led to a rapid change in perception of the past. Three models of the future, which, according to Pierre Nora, defined the face of the past (the future as a restoration of the past, the future as progress and the future as a revolution) that existed until recently, have now lost their relevance. Today, absolute uncertainty hangs over the future. The inability to predict the future poses certain challenges to the present. The end of any teleology of history imposes on the present a debt of memory. Features of the life of memory, the specifics of its state and functioning directly affect the state of identity, both personal and collective. Distortion of memory, its incorrect work, and its ideological manipulation can give rise to an identity crisis. The memorial phenomenon is a certain political resource in a situation of severe socio-political breaks and changes. In the conditions of the economic crisis and in the absence of a real and clear program for future development, the state often seeks to turn memory into the main element of national consolidation.

Effective counteraction to corruption remains relevant in some countries of Eastern Europe and the former Soviet Union, given that manifestations of corruption are a real obstacle to the realization of human rights, social justice, economic development and jeopardizes the proper functioning of a market economy. However, if such countries of the region, such as Poland, succeeded in ensuring the implementation of an effective anti-corruption policy, a number of post-Soviet countries, in particular Ukraine, faced significant obstacles to overcoming corruption and effectively implementing national anti-corruption policies. Therefore, within this article, a comparative legal analysis of the anti-corruption legislation of these countries has been carried out. The state of implementation of national anti-corruption policies and the formulated conclusions, which provide answers to the questions of improving the implementation of national anti-corruption policy, in particular Ukraine, are considered. Thus, the existence of modern national anti-corruption legislation that best meets the requirements and recommendations on which the state relies on relevant international treaties can be the key to successful anti-corruption efforts.

The article contains a biography of the famous Russian paleontologist V.E. Garutt (1917–2002), the oldest research worker of the Zoological institute of Russian Academy of Sciences, who studied the Pleistocene elephants of Northern Eurasia. He published more than 70 scientific papers on the origin and evolution of elephants of mammoth line, the morphology, changeability and features of the development of ancient proboscides. V.E. Garutt suggested two subfamilies Primelephantinae and Loxodontinae. He is the author of several taxa of fossil elephants of the generic, specific and subspecific levels. On his initiative, the skeleton of the Taimyr mammoth was adopted as the neotype of the woolly mammoth Mammuthus primigenius. He actively defended the independence of the genus Archidiskodon. A number of famous and important for the science paleontological specimens (skulls and skeletons of southern elephants, trogontherine and woolly mammoths, woolly rhinoceroses and elasmotherium) were restored and mounted by V.E. Garutt. They adorn a number of museums and institutes in Russia (St. Petersburg, Stavropol, Pyatigorsk, Azov, Rostov-on-Don) and abroad (Tbilisi, Vilnius, Edersleben, Sangerhausen). In addition, V.E. Garutt was an active popularizer of paleontological science. He collected a scientific archive on the remains of elephants from many regions of the former Soviet Union and some countries of Western Europe, which is now stored in the Azov museum-reserve (Azov). Several grateful pupils began their way in paleontology under the leader ship of V.E. Garutt. And they continue active work nowadays.

The last twenty-five years of the twentieth century were freighted with important moments for historians of economic thought: the collapse of the Keynesian consensus, the rise (and fall) of monetarism, the collapse of the former Soviet Union and the other Marxist-Leninist states in central and eastern Europe, the rise of neo-liberalism, and arguments over the possible emergence of a “New Economy” following the internet investment boom at the end of the 1990s. Each of these moments will require its own history as we slowly move away from the tumult of the times and begin to weigh them for their own significance. But several of the moments have a common iconic face in Margaret Thatcher, the Prime Minister of Great Britain from 1979 to 1990. Few other individuals so readily embody the sense of the times. Thatcher's election—a full year and a half before Ronald Reagan's—marks for many people the moment when Keynesian policies finally and irretrievably lost their legitimacy. Likewise, the timing of her election, just two months before Paul Volcker's selection as the chair of the Federal Reserve Board of Governors in the United States, also means that for many people Thatcher's is the public face of monetarism's ascendancy. Finally, there is probably no one person whose name is so clearly associated with the rise of free market thinking and neo-liberalism during the end of the twentieth century.

When they saw so many ridiculous, ramshackle institutions, survivals of an earlier age, which no one had attempted to co-ordinate or adjust to modern conditions and which seemed destined to live on despite the fact that they had ceased to have any present value, it was natural enough that thinkers of the day should come to loathe everything that savored of the past and should desire to remold society on entirely new lines. —Alexis de TocquevilleThe dissolution of empires has been one of the distinguishing and most consequential characteristics of the twentieth century. The popular struggles for national sovereignty that have helped to destroy these empires have sometimes (although certainly not always) been fused with attempts to change radically the socioeconomic institutions inherited from the imperialists. The result of this fusion has been nationalist revolution—or revolutionary nationalism—another phenomenon largely unique to the present century. Most recently, in the Eastern European satellites of the former Soviet Union, imperial domination not only generated a nationalist opposition but also unwittingly radicalized it—albeit in a very peculiar way that I explain below. Thus, the Eastern European revolutions of 1989, as Pavel Campeanu (1991: 806–7) has pointed out, had “a dual nature: social, since their goal was to destroy the socioeconomic structures of Stalinism, and national, since they aspired to re-establish the sovereignty of the countries in question.”
