Conodonts are very precise tools for global stratigraphic correlation of Devonian deposits. They can be correlated at the level of standard conodont zones even for basins having very different geological structure. In this paper Devonian conodont correlations between north-western margin of the Kuznetsk Basin (Siberia) and eastern Serbia are demonstrated. The geology of both regions is quite different. East Serbian zone is the southern tip of the Carpathian folded area (Carpatho-Balkanides). Middle Paleozoic carbonate and terrigenous deposits (Silurian, Devonian and Lower Carboniferous) are replaced by Hercynian molasse, and sedimentation continued throughout the Mesozoic and Cenozoic Eras. Rocks were exposed to repeatedly tectonic effects, olistoliths, olistostromes are widespread. Middle Paleozoic sediments, including Devonian, are localized within separate small tectonic blocks, often shifted from its place and form allochthons. In the western part of the Altai-Sayan folded area the Middle Paleozoic sediments have undergone folding and orogeny during the Hercynian phase of tectonic and magmatic activity, but since that time the continental conditions have been dominant in this region. The Devonian deposits are well represented in the marginal parts of the Kuznetsk Basin. In both regions the Devonian rocks have been well studied and the standard conodont zones varcus, gigas (rhenana) - linguiformis, crepida, expansa and praesulcata were established.

Abstract Chełmno is a town in the north-western part of the Chełmno Lakeland. It is one of few towns in Poland to have fully preserved its medieval defensive walls. Its touristic and natural environs make it a popular tourist destination. The town’s location near the escarpment of the Vistula valley mean that the preserved historical structures (including the defensive walls) are under threat. A few years ago a buttress became detached and two sections of the defensive walls collapsed. One part was rebuilt (the site where the studies were conducted), while the second part remains unrestored. Bricks are also progressively coming away. This situation may be the result of several factors, although the authors claim that the most important are the geological structure and the wall foundations (which are shallow, at a depth of 1-2 m, with the wall having been built up higher in the 16th century).

One of the results of the educational reform of the 1860s was the formation of the regular personnel of village teachers. In Vilna educational district the goal was not to invite teachers from central Russia, but to train them on the spot by establishing special seminaries. Trained teachers were supposed to perform the role of «cultural brokers» – the intermediaries between local peasants and the outside world, between the culture of Russian intelligentsia and the culture of the Belarusian people. The article examines how officials and teachers of Vilna educational district saw the role of rural teachers as «cultural brokers» in the context of the linguistic and cultural diversity of the North-Western Provinces. According to them, the graduates of the pedagogical seminaries had to remain within the peasant estate and to keep in touch with their folk «roots». The special «mission» of the village teachers was in promoting the ideas of «Russian elements» and historical proximity to Russia among Belarusian peasants.

In this article I discuss how illegal substance consumption can act as a tool of resistance and as an identity signifier for young people through a covert ethnographic case study of a working-class subculture in Genoa, North-Western Italy. I develop my argument through a coupled reading of the work of the Centre for Contemporary Cultural Studies (CCCS) and more recent post-structural developments in the fields of youth studies and cultural critical criminology. I discuss how these apparently contrasting lines of inquiry, when jointly used, shed light on different aspects of the cultural practices of specific subcultures contributing to reflect on the study of youth cultures and subcultures in today’s society and overcoming some of the ‘dead ends’ of the opposition between the scholarly categories of subculture and post-subculture. In fact, through an analysis of the sites, socialization processes, and hedonistic ethos of the subculture, I show how within a single subculture there could be a coexistence of: resistance practices and subversive styles of expression as the CCCS research program posits; and signs of fragmentary and partial aesthetic engagements devoid of political contents and instead primarily oriented towards the affirmation of the individual, as argued by the adherents of the post-subcultural position.

The traditional view that the Brazilian Amazonia is located in a tectonically stable area since the Cretaceous is changing in front of the increasing documentation of fault reactivations even during the Holocene. How the sedimentary record has responded to these events is an issue that remains to be approached with basis on field data. This work focuses on the stratigraphic correlation of late Quaternary deposits from eastern Marajó Island, with the goal of demonstrating the role of fault reactivation on the origin and preservation of these deposits. Despite the location in a stable platform of a continental passive margin, three studied stratigraphic units display significant vertical offsets that define two depocenters that are better explained through tectonic displacements. This interpretation is reinforced by several morphostructural features related to faults that occur between the studied drills. Without the influence of tectonics, sediment preservation in this characteristically low-lying terrain would have been negligible. The results of the present work motivate to look for other tectonically-influenced areas in Amazonia, which similarly might have acted as sites for sediment accommodation during the late Quaternary. These sedimentary records have great potential to be the source of valuable information for reconstructing Quaternary geological events in Northern Brazil.

An assessment of spatial changes in the timber industry complex in Russia has been carried out. Based on the estimates obtained, it was concluded that the traditional leaders, which include the regions of the North-Western and Siberian Federal Districts, continue to determine the all-Russian trends in the timber industry. In the production of unprocessed wood and sawn wood, there has been a significant spatial shift in favor of the regions of the Siberian Federal District, which entailed an increase in the production of timber products on a national scale. The main factors that influenced the spatial shifts in the timber industry are identified, the leading role of the factors of external markets and internal institutional changes is shown, and their influence on the parameters of regional timber industry complexes is considered

Theoretical and methodological base of the research includes socio-demographic, thesaurus and generational approaches. Scientific and methodical base of the research is a survey held in the Volga Federal District (Republic of Tatarstan) and the North-Western Federal District (Vologda Region). This study reflects the rupture of the family thesaurus, the loss of the authoritarian value system of family relations, which leads to the leveling of responsibility, distortion of the forms of family relations, and orientation to false family values. Transmission of marital and reproductive behavior of Russian men in intergenerational aspect is analyzed on the base of the empiric survey, the role of father in comparative correlation with transmission of value heritage of fatherhood image is discovered. The scientific novelty of the study is to identify, based on the original methodology, problem areas for the implementation of various models of generative behavior of Russian men in the conditions of transformation of family and parenting institutions.
