AbstractThe Carboniferous chronostratigraphic scale is a hierarchy of two subsystems, six series and seven stages developed during nearly two centuries of research. Carboniferous stage nomenclature developed with the proposal of numerous regional stages/substages based primarily on palaeobotanical, foraminiferal and ammonoid biostratigraphy, especially in Western Europe, the former Soviet Union, China and the USA. From the regional stages, seven ‘global stages’ have been identified (in ascending order): Tournaisian, Visean, Serpukhovian, Bashkirian, Moscovian, Kasimovian and Gzhelian. Three of the four ratified Carboniferous GSSPs use conodont evolutionary events as the primary signal for correlation – bases of Tournaisian, Bashkirian and base of Asselian. The GSSP of the Visean base has a foraminiferal event as its primary signal. Issues in the development of a Carboniferous chronostratigraphic scale include the rank of chronostratigraphic units, provinciality, conodont biostratigraphy, palaeobotanical biostratigraphy and the development of astrochronology and other methods of chronology and correlation.

Previous analyses suggest children with tuberculosis (TB) are no more or no less likely to have multidrug- or rifampicin-resistant TB (MDR/RR-TB) than adults. However, the availability of new data, particularly for high MDR/RR-TB burden countries, suggest updates of country-specific estimates are warranted.We used data from population-representative surveys and surveillance collected between 2000 and 2018 to compare the odds ratio (OR) of MDR/RR-TB among children (<15 years) with TB, compared to the odds of MDR/RR-TB among adults (≥15 years) with TB.In most settings (45/55 countries), and globally as a whole, there is no evidence that age is associated with odds of MDR/RR-TB. However, in some settings such as former Soviet Union countries in general, and Georgia, Kazakhstan, Lithuania, Tajikistan and Uzbekistan in particular, as well as Peru, MDR/RR-TB is positively associated with age ≥15. Meanwhile, in Western Europe in general, and the UK, Poland, Finland and Luxembourg in particular, MDR/RR-TB is positively associated with age <15. Sixteen countries had sufficient data to compare over time between 2000–2011 and 2012–2018, with evidence for decreases in the OR in children compared to adults in Germany, Kazakhstan and the USA.Our results support findings that in most settings a child with TB is as likely as an adult with TB to have MDR/RR-TB. However, setting-specific heterogeneity requires further investigation. Further, the OR for MDR/RR-TB in children compared to adults is generally either stable or decreasing. There are important gaps in detection, recording and reporting of drug resistance among paediatric TB cases, limiting our understanding of transmission risks and measures needed to combat the global TB epidemic.

Nepal’s strategic position and open border with India and China have attracted unusually high attention, particularly during the Cold War era, not only from these two large neighbours but also from European countries, the USA and the former Soviet Union. However, despite decades of aid inflows, Nepal remains one of the poorest countries. While debate over aid–growth nexus remains unsettled, our empirical results do suggest that aid fragmentation is detrimental to growth, perhaps due to increased administrative burden to manage a large number of small projects and meet reporting requirements of the donor community. While we find that aid is good for growth, attracting uncoordinated and fragmented aid without the need for assessment can, in fact, do more harm than good. These findings point to the importance of coordinated aid approach not only at the country level but also among the donor community.

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 author explores the phenomenon of today's ethnic conflicts which are less frequently turning into the wars between states. The author uses the cases of the countries of former Soviet Union, Western Europe, Africa in order to examine important aspects of the ethnic conflicts settlement. It is concluded that the heart of the problems is the correlation between two fundamental principles of the international law (usually regarded as antagonists in terms of the settlement of such conflicts). Namely, these are the principle of states’ territorial integrity and the principle of peoples’ right to self-determination.

This chapter begins with a review of the book’s argument and principal findings. It then discusses theoretical and applied lessons for the study of sexual citizenship and the practice of LGBT activism in the new EU member-states of postcommunist Europe. The chapter’s remaining sections reflect on the argument’s implications for other social issues and regional contexts. These include the women’s movement in contemporary Poland, Roma activism in Hungary, and LGBT activism outside the sphere of potential EU applicant-states (especially the former Soviet Union and Latin America). Animating this discussion is the question of how to account for instances when social movements fail to thrive, or even wither, in the face of backlash. A second animating question is what counts as social movement “success,” policy gains or organizational development? The chapter concludes with some speculation about LGBT activism in the US and Western Europe in light of the contemporary turn to populist-nationalist politics in both places.

Purpose – The purpose of this paper is to examine the effect of acculturation on immigrant consumers’ loyalty. The authors posit that the acculturation orientation of immigrants determines their consumer loyalty to both ethnic and mainstream brands and stores. Design/methodology/approach – Using a sample of Hispanic consumers in the USA and consumers from the former Soviet Union in Israel, this study tests a model in which two acculturation continua, original culture maintenance and host culture adaptation, serve as antecedents for immigrants’ consumer loyalty. Findings – Acculturation determines the extent of immigrants’ consumer loyalty. Both acculturation continua are associated with distinct loyalty patterns that are similar across the two immigrant groups. Research limitations/implications – Despite sampling limitations, the paper demonstrates that immigrants’ acculturation orientation influences their loyalty to ethnic and mainstream brands and stores. Shared by ethnic consumers in two culturally diverse markets, this relationship transcends geographic boundaries. Practical implications – The results provide insights for marketers with respect to the development of segmentation and positioning strategies and tactical implementations that address the preferences of ethnic consumers. Social implications – This paper highlights the importance of understanding the unique needs of ethnic consumers and addressing them. Successful integration of immigrant consumers into the marketplace can also help in their integration into the host society at large. Originality/value – Findings shed light on the commonalities and differences among immigrant groups in different national settings. The paper highlights the role of cultural transition as a key experience that affects immigrants regardless of specific environmental or situational circumstances.

AbstractWhile the ever more strongly felt presence of Muslims in western Europe has already stimulated numerous scholars of various social sciences to embark upon research on issues related to that presence, it is apparent that just a few studies and introductory text books have so far dealt with the evolution of Muslim communities in other parts of Europe, especially in countries of central, eastern, and northern Europe. Without appreciation of and comprehensive research into the more than six-hundred-year-long Muslim presence in the eastern Baltic rim the picture of the development of Islam and Muslim-Christian relations in Europe remains incomplete and even distorted. Therefore, this article argues for the necessity of approaching the history of Islam and Muslims in Europe from a different and ultimately more encompassing angle by including the minorities of Muslim cultural background that reside in the countries of the European part of the former Soviet Union—the Baltic states and Belarus. Besides arguing that it is necessary to reconsider and expand the research field in order to develop more profound studies of Islam and Muslims in Europe, the article also outlines suggestions as to why the Muslim history in the eastern Baltic rim has been generally excluded from the history of Islam in Europe.

The spread of nuclear weapons outside the Western world has become the most important nuclear issue since the end of the Cold War. By contrast, the debate about Europe's nuclear strategy has subsided. Nuclear collaboration in Western Europe now seems an unlikely prospect and so too does proliferation, despite instability in the former Soviet Union, and occasional speculation about Germany's nuclear appetite. A very different atmosphere prevailed during the Cold War, when the need for a European nuclear force was endlessly debated, without any prospect of this political demand being fulfilled, and, in the late 1950s and 1960s, several European countries appeared to be at the threshold of obtaining nuclear power.

The past trends in tertiary education attainment of selected post-communist countries are investigated through population projections. Did a common higher education policy manifest itself through attainment levels, and how did the situation change after the collapse of the Soviet regime? The approach is based on comprehensive back-projections ranging from year 2000 to 1970. Descriptive findings for most countries show that the level of tertiary education attainment for women has surpassed that of men sooner than in Western Europe. Results are discussed in light of individual countries’ pre-war higher education models and former communist policy, and possible implications are derived for future study of higher education attainment.
