AbstractRolling stock connection systems are key to running longer and heavier trains as they provide both the connections of vehicles and the damping, providing the longitudinal suspension of the train. This paper focuses on the evolution of both connection and stiffness damping systems. Focus is on freight rolling stock, but passenger draw gears are also examined. It was found that connection systems have evolved from the buff and chain system used in the pioneer railways of the 1800s to the modern auto-coupler connection systems that are in-service worldwide today. Refined versions of the buff and chain coupling are, however, still in use in the EU, UK, South America and India. A wide range of auto-coupler systems are currently utilised, but the AAR coupler (Janney coupler) remains the most popular. A further variation that persists is the SA3 coupler (improved Wilson coupler) which is an alternative auto-coupler design used mainly throughout the former Soviet Union. Restricting the review to auto-coupler systems allowed the paper to focus on draft gears which revealed polymer, polymer-friction, steel spring-friction, hydraulic draft gears and sliding sill cushioning systems. Along with the single compressive draft gear units balanced and floating plate configurations are also presented. Typical draft gear acceptance standards are presented along with modelling that was included to aid in presentation of the functional characteristics of draft gears.

Why Putin Started War Against Ukraine? The author analyzes the causes and consequences of undeclared war of Russia against Ukraine. Among the main reasons – the desire to restore Russian leadership’s geopolitical influence in the former Soviet Union by building a new type of empire. In order to reach it official Moscow uses a wide range of tools - from economic pressure and blackmail to armed aggression on the territories of the former USSR. The author is convinced that the annexation of the Crimea and the undeclared war of Russia against Ukraine were the result of revanchist policy of Russian President Vladimir Putin aimed at the return of influential world power status. Achieving this goal involves prevention of Europeanisation and democratization of post-Soviet countries, the main jewel among which is Ukraine. Exit from the influence of Russia is possible, according to the author, through the integration of Ukraine into the EU and NATO.

The lysis of bacteria by bacteriophage was independently discovered by Frederick Twort and Felix d?Herelle but it was d?Herelle who proposed that bacteriophage might be applied to the control of bacterial diseases. Within the former Soviet Union (FSU), bacteriophage therapy was researched and applied extensively for the treatment of a wide range of bacterial infections. In the West, however, it was not explored with the same enthusiasm and was eventually discarded with the arrival of antibiotics. However, the increase in the incidence of multi-antibiotic-resistant bacteria and the absence of effective means for their control has led to increasing international interest in phage therapy and in the long experience of the Eliava Institute. The Eliava Institute of Bacteriophage, Microbiology and Virology (IBMV), which celebrates its 85th anniversary in 2008, was founded in Tbilisi in 1923 through the joint efforts of d?Herelle and the Georgian microbiologist, George Eliava.

The development of LGBT movements and interest groups in Eastern Europe and the former Soviet Union reflects the region’s unique political development with respect to the experience of communism, the transition to democracy in the 1990s, the expanding influence of international institutions like the European Union (EU), and, most recently, trends of democratic backsliding and even reversion to outright authoritarian rule in some countries. Each of these aspects of the region’s political development has engendered debate among scholars and activists. There is consensus that the experience of communism strongly circumscribed not only the possibilities for activism but also, in some instances, even the possibilities for articulating LGBT identities. Nevertheless, a survey of the scholarship on postcommunist LGBT politics indicates divergent trajectories between countries of the former Soviet Union, where LGBT identities are less established and activism is less organized, and the former satellite states of Eastern Europe, whose experience under communism was shorter and, arguably, less intense. Without ignoring the evident deficits of Eastern Europe’s LGBT activism in the 1990s, its LGBT people benefited relative to counterparts in the former Soviet Union from a generally more successful transition to democracy and a greater degree of exposure to West European institutions, in particular the EU. The process of applying for EU membership, many scholars argue, advantaged these countries’ LGBT movements vis-à-vis their counterparts in the former Soviet Union by pressuring national governments to be more accommodating and by socializing elites and publics to Western Europe’s comparatively tolerant values and LGBT rights norms. Adjusting to these norms was sometimes contentious, but several scholars argue that, where conservative backlash against LGBT rights occurred during the EU’s first round of expansion in 2004 to 2007, it generally helped domestic activism by increasing its visibility and level of organization. Not all are so optimistic about the EU’s impact on LGBT activism, however, particularly those studying Yugoslavia’s successor states, for whom the EU accession process occurred later or is still ongoing. These scholars emphasize the difficulties of squaring EU norms about LGBT rights with national identity, particularly given the EU’s sometimes colonial-like relations with postcommunist societies. Others note that transnational rights advocacy supported by the EU has been matched by the rise of transnational antigay activism, and that the clash of transnational activism stalemates domestic progress on LGBT-friendly policies. Such critiques appear increasingly relevant as trends of democratic backsliding have emerged since the 2010 world financial crisis in former “success cases” of postcommunist transition and EU integration, notably Hungary and Poland. The latter’s democratic backsliding occurs within the larger context of Russia’s reversion to authoritarianism after the brief political opening of the 1990s. Across these three countries, governing elites have shown a readiness to make use of LGBT issues to define their illiberal ideologies and to mobilize voters. Whether these developments portend a narrowing of differences among LGBT movements in the former Soviet Union and Eastern Europe is a key question for future scholars.

Over the past 2 years the Global Initiative on Psychiatry has developed a wide range of initiatives in the fields of prison mental health and forensic psychiatry in Eastern Europe and the former Soviet Union. Both areas, until recently, were either ignored or deliberately avoided. This is not coincidental. The prison systems in the former Eastern bloc are in essence military organisations with a strict hierarchy and a rather tarnished past. Although some reform programmes in this field were implemented or started during the past decade (e.g. by Prison Reform International and the London Institute for Prison Studies), none of these projects has involved mental health services within the penitentiary system. A society that often limits itself to locking away those who have committed crimes or are suspected of having committed them, and pays only little attention to the physical and emotional well-being of those imprisoned, does not see the mental health of these persons as a priority. Equally unimportant seems to be the mental health of those who guard the prisoners and who are under constant stress.

Abstract Support for democratisation and democracy has become one of the leading topics in a wide-ranging debate over the state of democracy in the contemporary world. The European Union became an important player in global politics, one with an ambitious programme for the spreading and supporting of democracy and the process of democratisation in Eastern Europe. Hence the author’s attempt at addressing the following question: what actions and strategies have and are being undertaken by the EU to facilitate the above-mentioned processes? The aim of the paper is to describe and assess the strategies and actions of the European Union in the field of supporting democratisation and democracy in selected countries of the former USSR (e.g. Belarus, Georgia, Moldova and Ukraine), additionally well-fitting to the concept of Eastern Partnership, in the last decade of XX and the first decade of XXI Century. The paper also aims to present which procedures and standards (that are supposed to guarantee their usefulness and effectiveness) are being used by the EU. The emphasis has been placed primarily on the processes of democratisation, their mileage, specificity and possible strategies for supporting democratic development, as well as its potential for consolidation, in the countries of the former Soviet Union. In order to conduct the research it is necessary to assess the political, social and economic conditions in the researched countries. It is to be stressed that one should be aware of the complexity and dynamics of the described processes whilst evaluating the EU’s initiatives. The papers topic was chosen due to the importance and currentness of the researched EU actions and their results.

The effects of divergent historical experiences, of differential exposure to the world outside the former Soviet Union, and of divergent industrial structure–all point in the direction of enormous attitudinal and evaluative cleavages across the regions of Ukraine. When we compare regional differences in perspectives on the political economy in Ukraine and views about whether Russia and Ukraine should be separate states, these differences are readily discernible. By extending the scope of items examined and by making explicit comparisons between data from Ukrainian and Russian samples, however, we achieve a somewhat more optimistic view about the prospects for community building in Ukraine. The relatively consensual assessment of citizenship conditions and the wide range of foreign policy matters about which dispositions of Ukrainians are separable from those of persons from regions reported in this paper provide some evidence of an emerging Ukranian political community.

Why has China been so much more successful than the former Soviet Union and its East European satellites in making the transition away from a centrally planned economy? While other articles address a wide range of explanations of China's success, this one explores the possible contri- bution of China's grass roots social organization, and particularly its family and kinship structures. Attention is drawn to social factors by the obvious fact that China, through its spectacular recent growth, has taken its place among other Chinese (and Chinese cultural orbit) populations in East Asia, reinforcing the position of this region as the most dynamic portion of the world economy. Could China share with other Chinese populations, despite more than 30 years of collectivist socialism, grass roots social structures that are conducive to economic growth under the proper conditions - social structures that are different in strategically important ways from those in the former Soviet Union and Eastern Europe?

AbstractThis paper deals with 'development' — a state discourse formulated initially to transform the ethnic minority societies in China's southwest upon the founding of the People's Republic (PRC) — and how this state discourse has inadvertently served the interests of the ethnic elites in the course of China's current economic reforms. Half a century on, socialism on China's periphery has transformed from being an alien concept to acquiring its present catchphrase-status, underscoring a complex learning process on the part of ethnicminority cadres. Going beyond the conventional static view of binaries (typically, as often seen in English writings, Han versus non-Han and state versus society), this study explores the interaction of a wide range of forces within the political system that shape the dynamics of ethnicity and ethnic relations in China. It shows, as much as ethnic cadres are subject to certain restrictions of the local offices in which they serve, their manoeuvring and creative manipulation of the official language exerts equal constraints on the central state, especially in the context of economic development and nationalities policy. Such a mode of interaction generates, and at the same time mitigates the tension within the bureaucratic system. In this light, the 'embrace' of socialism by the ethnic cadres may indeed be seen as an adaptation through which they justify their relationship with the state. The magic of socialism is, therefore, not the ideology itself, but the policy implementation in its name. In a multiethnic region like southwest China, where ethnic identities remain fluid and local nationalism largely reflects inter-community relations vis-à-vis the state, socialism serves a unique conflict management function. This particular mechanism perhaps offers an explanation for the marked contrast between the former Soviet Union and PRC: in the former, socialism collapsed as a political system but not as a set of values, whereas, in the latter, socialism may have lost its appeal to the majority of the population as a set of values, but has not collapsed as a system.

Since 1997, the EuroSOMNET project, funded by the EU-ENRICH programme, has assembled a metadatabase, and separate experimental databases, of European long-term experiments that investigate changes in soil organic matter. In this paper, we describe the WWW-based metadatabase, which is a product of this project. The database holds detailed records of 110 long-term soil organic matter experiments, giving a wide geographical coverage of Europe, and includes experiments from the European part of the former Soviet Union, many of which have not been available previously. For speed of access, records are stored as hyper-text mark-up language (HTML) files. In this paper, we describe the metadatabase, the experiments for which records are held, the information stored about each experiment, and summarize the main characteristics of these experiments. Details from the metadatabase have already been used to examine regional trends in soil organic matter in Germany and eastern Europe, to construct and calibrate a regional statistical model of humus balance in Russia, to examine the effects of climatic conditions on soil organic matter dynamics, to estimate the potential for carbon sequestration in agricultural soils in Europe, and to test and improve soil organic matter models. The EuroSOMNET metadatabase provides information applicable to a wide range of agricultural and environmental questions and can be accessed freely via the EuroSOMNET home page at URL: http://www.iacr.bbsrc.ac.uk/aen/eusomnet/index.htm.
