For more than twenty years, the Institute of Slavic Studies of the Russian Academy of Sciences celebrates the Day of Slavic Writing and Culture with a traditional scholarly conference.”. Since 2014, it has been held in the young scholars’ format. In 2019, participants from Moscow, St. Petersburg, Kazan, Togliatti, Tyumen, Yekaterinburg, and Rostov-on-Don, as well as Slovakia, the Czech Republic, Hungary, and Romania continued this tradition. A wide range of problems related to the history of the Slavic peoples from the Middle Ages to the present time in the national, regional and international context were discussed again. Participants talked about the typology of Slavic languages and dialects, linguo-geography, socio- and ethnolinguistics, analyzed formation, development, current state, and prospects of Slavic literatures, etc.

Extensive soil sampling and screening assessment of ecosystem risks combined with a multidimensional statistical analysis were used to estimate and spatially characterize the ecosystem risks stemming from the contamination of floodplain soils in the Czech Republic. We proved structural differences in regional pollution patterns where different regional/local pollution sources led to various nature and extent of the environmental load of floodplain soils. The established spatial patterns helped reveal the areas where soils do not meet soil quality standards and where the ecosystem risks were elevated. Furthermore, the results allowed to establish priority contaminants of flood affected areas in various catchments in the Czech Republic. Combining both the magnitudes of estimated ecosystem risks and structural characteristics of pollution profiles, the highest estimated risks showed the localities with high contents of organochlorine pesticides, several samples connected to geochemical anomalies of metallogenic zones (deposits), and localities with a long history of industrial load. Since extreme weather events have recently become more frequent, our results highlight the importance of a continual monitoring of pollutant turnover in floodplain soils with a high flood frequency.

Purpose The purpose of this paper is to evaluate the historical pollution of the Hostivar Reservoir (largest reservoir in Prague) sediment by metals, polyaromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) and identify the trends in pollution of aquatic environment. Design/methodology/approach Core samples, 140 cm long, recording the 45-year history of the reservoir, were separated to 5 cm width subsamples (approximately 1.5 years of sedimentation) and analyzed for metals (Cd, Pb, Cu, Zn, Cr, Ni, Al), PAH and PCB. Following methods were used: US EPA 3051 for metals, US EPA 505 and US EPA 8082 A for PCB, and ISO 18287:2006 for PAH. Findings Most of the contaminants had the highest concentration at the beginning of the existence of the reservoir, suggesting that the contamination results from construction activities. Significant decrease of Pb occurred in the second half of the 1990s. It was caused by termination of the addition of lead as a detonation suppressant to the gasoline. Most concentrations of PAHs, PCBs and metals, except copper do not present eco-toxicological risk. Practical implications The results show the volume of priority pollutants removed from the reservoir by sediment extraction, and point risk to the terrestrial environment due to application of the sediment in the construction of a noise protecting wall. Originality/value The paper presents unique data about historical contamination of the largest reservoir in Prague, the capital of Czech Republic. It shows how the watershed and the construction phase of the dam cause a pollution of the reservoir sediment and possible environmental risk for aquatic biota.

The article deals with the description of football hooligans in the countries of Visegrad Group (Czech Republic, Slovakia, Poland, Hungary). Text describes history of this phenomenon in the central Europe in the context of European Football Championships of 2012 and 2016. Particular hooligans’ groups, the basic characteristics, relations and manifestations of these groups are briefly presented. In the final part there are outlined particular actors participating in tackling with football hooligans, including legislative procedures stemming from European Convention. In the conclusion itself there is discussed also police’ cooperation during big football championships.

The Town

Synanthedon mesiaeformis (Herrich-Schäffer, 1846) has been found in the Czech Republic and in Spain for the first time. The species was found in the south-easternmost part of the Czech Republic, near the town of Břeclav (faunistic quadrat 7267) in May 2008. The holes and pupae were found only in one, solitary growing group of trees about 20 years old. This finding place lies at a distance of more than 250 km from the localities in SW Hungary and about 550 km from the localities in eastern Poland. In June 2008, the species was found also in alders growing in the flat river alluvium on gravel sands between La Jonquera and Figueres in northern Catalonia. This locality is in a close contact with the fin­ding places near Perpignan and Beziers in southern France. The diagnostic morphological characters and bionomics of this species are briefly summarized and figured. The history of its distribution research is recapitulated and the causes of its disjunct range are discussed as follows. The present disjunct range represents a residual of the former distribution over the warmer and moister postglacial period; landscape modifications and elimination of solitary alder trees as „weeds“ from the 18th up to the mid-20th century in large areas of Europe; narrow and partly unknown habitat requirements and specific population ethology; an insufficient level of faunistic investigations in several parts of sou­thern and eastern Europe.

Abstract The article’s aim is to compare the opposite processes of social exclusion and inclusion in South Africa and in the Czech Republic, in the past and at the present time. Even though these societies differ culturally and geographically, the comparison of some important factors, which are causing the exclusion of some people groups, might be interesting. In both cases we will closely follow the social, ethnic and racial groups, which are mostly excluded in the given environment. In South Africa it concerns Black and Coloured Africans, and in the Czech Republic the Roma ethnic minority group, the only ethnic group which is to a high extent excluded. In the history of these two countries we can find a similar historic aspect, both of them had experienced totalitarian regimes. Today, with the benefit of more twenty years, we can see the changes, which both these countries have undergone, and observe as well how these changes influenced the processes of inclusion and exclusion of the given social, racial and ethnic groups.

The book deals with the historical contacts of Czech, Slovak and Russian peoples, the beginning of mass Czech and Slovak relocation to Russia, Russian official policy towards settlers. The author marks the main centers of their residence, pauses in detail on public organizations created by them, ties with the historical homeland, their participation in the Slavic movement. Special attention is paid to the prominent representatives of the compatriots. The monograph analyzes the social, professional composition of the Czech and Slovak diasporas, evaluates their contribution to the economic and cultural development of Russia. It is based on documents published and identified in the archives of Russia, Czech and Slovak republics, printing masters, memories and literature on the topic. The book is intended for specialists in the history of Russia, the Czech Republic and Slovakia, as well as all those interested in the ties of the peoples of the three countries.

Special Circumstances

The article describes a range of features typical of the manner in which Mongolians integrate themselves into an alien culture, particularly their way of life in the Czech Republic. Since the migration history of Mongolian minority living in our country is relatively short, the inquiry into their special circumstances required that we set up several focus groups at those places of Czechia where their populations are largest, namely in the regions of Highland, Pardubice, Zlín and Karlovy Vary. Special attention was paid to their involvement in regional policy in dependence on their numbers. As also follows from what was said above, the number of available interpreters and translators offering a command of both Czech and Mongolian languages is insufficient and does not meet the needs of integration.
