Abstract. On 7 March 2014 (UTC), Malaysia Airlines flight 370 vanished without a trace. The aircraft is believed to have crashed in the southern Indian Ocean, but despite extensive search operations the location of the wreckage is still unknown. The first tangible evidence of the accident was discovered almost 17 months after the disappearance. On 29 July 2015, a small piece of the right wing of the aircraft was found washed up on the island of Réunion, approximately 4000 km from the assumed crash site. Since then a number of other parts have been found in Mozambique, South Africa and on Rodrigues Island. This paper presents a numerical simulation using high-resolution oceanographic and meteorological data to predict the movement of floating debris from the accident. Multiple model realisations are used with different starting locations and wind drag parameters. The model realisations are combined into a superensemble, adjusting the model weights to best represent the discovered debris. The superensemble is then used to predict the distribution of marine debris at various moments in time. This approach can be easily generalised to other drift simulations where observations are available to constrain unknown input parameters. The distribution at the time of the accident shows that the discovered debris most likely originated from the wide search area between 28 and 35° S. This partially overlaps with the current underwater search area, but extends further towards the north. Results at later times show that the most probable locations to discover washed-up debris are along the African east coast, especially in the area around Madagascar. The debris remaining at sea in 2016 is spread out over a wide area and its distribution changes only slowly.

Abstract. On the 7th of March 2014 (UTC), Malaysia Airlines flight 370 vanished without a trace. The aircraft is believed to have crashed in the southern Indian Ocean, but despite extensive search operations the location of the wreckage is still unknown. The only part of the aircraft that has been recovered so far is a small piece of the right wing. It was discovered 17 months after the disappearance on the island of Réunion, approximately 4,000 km from the assumed crash site. This paper presents a numerical simulation using high resolution oceanographic and meteorological data to predict the movement of floating debris from the accident. It combines multiple model realisations into a superensemble, and includes the discovery of debris on Réunion to improve the final result. The superensemble is used to predict the distribution of debris at various moments in time. The results for the initial probability density show good agreement with the current underwater search area. Results at later times show that the most probable locations to discover washed up debris are along the African west-coast and the southeast of Australia. The debris remaining at sea from late 2015 is spread out over a wide area and its distribution changes only slowly.

The present paper deals with rituals in a political discourse, namely the rituals employed by the right wing, Hindu nationalist movement, Vishwa Hindu Parishad (VHP), in its campaign for a Rama temple in the north Indian town of Ayodhya. As is probably well-known, VHP is part of a group of organizations known as the Sangh Parivar, or sangh family, which also includes the presently ruling Bharatiya Janata Party (BJP), and the ultranationalistic organization Rashtriya Swayamsevak Sangh, or RSS. The rituals of VHP are instruments of the construction of an ideal Hindu society and part of an encounter between Hindu-nationalist tenets and the secular, political establishment. However, the rituals employed by VHP can not be said to represent a separate ritual genre, since they are not different from similar, traditional Hindu rituals. What makes them different is their context and their motives, the fact that they do not serve ordinary material, eschatological, or soteriological aims, but rather political aims, as well as the fact that the ritual agents in this case do not seem to have a satisfactory juridical legitimacy to perform the rituals.

The article aims at identifying the characteristics shared by the right-wing populist civil movements of Western Europe and the USA and evaluating the possibility to use them for researching right-wing nationalist organizations in Russia. The movements selected for the comparison range from party-like electoral actors to unorganized protesters. They include as follows: The Five-star Movement (Italy), PEGIDA and the like (Germany), the English Defence League (the UK), the Tea Party Movement (the US). The authors identified several interrelated characteristics shared by these movements: (1) dealing with local, usually social, issues, (2) network-like structure of autonomous local groups building the agenda from below, (3) ideological ambivalence leading to replacing ideology with subculture, (4) digitalization of activism. Although in Russia there are no civic movements structurally or functionally identical to Western right-wing populists, the authors demonstrate that local social issues and civic responsibility have become important topics for some Russian nationalists (right-wing radicals) since the mid 2000s. The trends of deideologization and dealing with non-political local issues are researched mainly on the example of the “Frontier of the North” (Komi Republic). The authors conclude that some of the radical Russian nationalists are gradually declining their own independent agenda, following local protests instead. This opens up the possibility for right-wing organizations to become local civil society institutions and to participate successfully in local elections, similar to the “electoral break-through” of right-wing populists in the West. Although it is too early to speak about the deideologization of Russian nationalism, the article suggests that some nationalists are ready to mitigate ideological tensions to secure expanded social support. At the moment, nationalist organizations in Russia remain frozen between right-wing radicalism and emulating Western right-wing populism.

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.

Facing the decisive struggle between Nazism and Soviet communism for dominance in Europe, in 1942/43 Polish communists sojourning in the USSR espoused anti-German concepts of the political right. Their aim was an ethnic Polish ‘national communism’. Meanwhile, the Polish Workers’ Party in the occupied country advocated a maximum intensification of civilian resistance and partisan struggle. In this context, commentaries on the Nazi judeocide were an important element in their endeavors to influence the prevailing mood in the country: The underground communist press often pointed to the fate of the murdered Jews as a warning in order to make it clear to the Polish population where a deficient lack of resistance could lead. However, an agreed, unconditional Polish and Jewish armed resistance did not come about. At the same time, the communist press constantly expanded its demagogic confrontation with Polish “reactionaries” and accused them of shared responsibility for the Nazi murder of the Jews, while the Polish government (in London) was attacked for its failure. This antagonism was intensified in the fierce dispute between the Polish and Soviet governments after the rift which followed revelations about the Katyn massacre. Now the communist propaganda image of the enemy came to the fore in respect to the government and its representatives in occupied Poland. It viewed the government-in-exile as being allied with the “reactionaries,” indifferent to the murder of the Jews, and thus acting ultimately on behalf of Nazi German policy. The communists denounced the real and supposed antisemitism of their adversaries more and more bluntly. In view of their political isolation, they coupled them together, in an undifferentiated manner, extending from the right-wing radical ONR to the social democrats and the other parties represented in the underground parliament loyal to the London based Polish government. Thereby communist propaganda tried to discredit their opponents and to justify the need for a new start in a post-war Poland whose fate should be shaped by the revolutionary left. They were thus paving the way for the ultimate communist takeover

One scenario put forward by researchers, political commentators and journalists for the collapse of North Korea has been a People’s Power (or popular) rebellion. This paper analyses why no popular rebellion has occurred in the DPRK under Kim Jong Un. It challenges the assumption that popular rebellion would happen because of widespread anger caused by a greater awareness of superior economic conditions outside the DPRK. Using Jack Goldstone’s theoretical expla-nations for the outbreak of popular rebellion, and comparisons with the 1989 Romanian and 2010–11 Tunisian transitions, this paper argues that marketi-zation has led to a loosening of state ideological control and to an influx of infor-mation about conditions in the outside world. However, unlike the Tunisian transitions—in which a new information context shaped by social media, the Al-Jazeera network and an experience of protest helped create a sense of pan-Arab solidarity amongst Tunisians resisting their government—there has been no similar ideology unifying North Koreans against their regime. There is evidence of discontent in market unrest in the DPRK, although protests between 2011 and the present have mostly been in defense of the right of people to support themselves through private trade. North Koreans believe this right has been guaranteed, or at least tacitly condoned, by the Kim Jong Un government. There has not been any large-scale explosion of popular anger because the state has not attempted to crush market activities outright under Kim Jong Un. There are other reasons why no popular rebellion has occurred in the North. Unlike Tunisia, the DPRK lacks a dissident political elite capable of leading an opposition movement, and unlike Romania, the DPRK authorities have shown some flexibility in their anti-dissent strategies, taking a more tolerant approach to protests against economic issues. Reduced levels of violence during periods of unrest and an effective system of information control may have helped restrict the expansion of unrest beyond rural areas.

Through a critical appropriation of Hannah Arendt, and a more sympathetic engagement with Theodor W. Adorno and psychoanalysis, this book develops a new theoretical approach to understanding Austrians’ repression of their collaboration with National Socialist Germany. Drawing on original, extensive archival research, from court documents on Nazi perpetrators to public controversies on theater plays and museums, the book exposes the defensive mechanisms Austrians have used to repress individual and collective political guilt, which led to their failure to work through their past. It exposes the damaging psychological and political consequences such failure has had and continues to have for Austrian democracy today—such as the continuing electoral growth of the right-wing populist Freedom Party in Austria, which highlights the timeliness of the book. However, the theoretical concepts and practical suggestions the book introduces to counteract the repression of individual and collective political guilt are relevant beyond the Austrian context. It shows us that only when individuals and nations live up to guilt are they in a position to take responsibility for past crimes, show solidarity with the victims of crimes, and prevent the emergence of new crimes. Combining theoretical insights with historical analysis, The Politics of Repressed Guilt is an important addition to critical scholarship that explores the pathological implications of guilt repression for democratic political life.

The present article examines the place of the Jewish question in the ideology of the monarchist (right-wing, “black hundred”) parties. In spite of certain ideological differences in the right-wing camp (moderate Rights, Rights and extreme Right-Wing), anti-Semitism was characteristic of all monarchist parties to a certain extent, in any case before the First World War. That fact was reflected in the party documents, resolutions of the monarchist congresses, publications and speeches of the Right-Wing leaders. The suggestions of the monarchists in solving the Jewish questions added up to the preservation and strengthening of the existing restrictions with respect to the Jewish population in the Russian Empire. If in the beginning the restrictions were main in the economic, cultural and everyday life spheres, after the convocation of the State Duma the Rights strived after limiting also the political rights of the Jewish population of the Empire, seeing it as one of the primary guarantees for autocracy preservation in Russia, that was the main political goal of the conservatives.

The article examines the main forms and methods of agitation and propagandistic activities of monarchic parties in Russia in the beginning of the 20th century. Among them the author singles out such ones as periodical press, publication of books, brochures and flyers, organization of manifestations, religious processions, public prayers and funeral services, sending deputations to the monarch, organization of public lectures and readings for the people, as well as various philanthropic events. Using various forms of propagandistic activities the monarchists aspired to embrace all social groups and classes of the population in order to organize all-class and all-estate political movement in support of the autocracy. While they gained certain success in promoting their ideology, the Rights, nevertheless, lost to their adversaries from the radical opposition camp, as the monarchists constrained by their conservative ideology, could not promise immediate social and political changes to the population, and that fact was excessively used by their opponents. Moreover, the ideological paradigm of the Right camp expressed in the “Orthodoxy, Autocracy, Nationality” formula no longer agreed with the social and economic realities of Russia due to modernization processes that were underway in the country from the middle of the 19th century.
