Vekua theory for the Helmholtz operator

Vekua operators map harmonic functions defined on domain in \mathbb R2R2 to solutions of elliptic partial differential equations on the same domain and vice versa. In this paper, following the original work of I. Vekua (Ilja Vekua (1907–1977), Soviet-Georgian mathematician), we define Vekua operators in the case of the Helmholtz equation in a completely explicit fashion, in any space dimension N ≥ 2. We prove (i) that they actually transform harmonic functions and Helmholtz solutions into each other; (ii) that they are inverse to each other; and (iii) that they are continuous in any Sobolev norm in star-shaped Lipschitz domains. Finally, we define and compute the generalized harmonic polynomials as the Vekua transforms of harmonic polynomials. These results are instrumental in proving approximation estimates for solutions of the Helmholtz equation in spaces of circular, spherical, and plane waves.

Between the lines: Konrad Wolf's 'Mama, ich lebe' and the dilemmas of betrayal

The article offers a close reading of Konrad Wolf’s anti-fascist Second World War film 'Mama, ich lebe' (DEFA, 1977). 'Mama, ich lebe', like all East German films about the Nazi past, deals with the re-founding of post-war Germany. Unlike the usual approach which focused on political redemption of the past crimes, Wolf’s approach explores rupture and failure of political agency as the pre-condition for a new beginning. The rupture is effected by the defection of four Wehrmacht soldiers who decide to cooperate with the Soviet enemy. Their betrayal of the national collective is ethically motivated and arises from their responsibility for the Soviet ‘other’. Its radicalness opens up a moment of utopian freedom and conciliation for the traitors. Yet the back side of betrayal is insecurity and confliction with regard to their role and roots. While the four meet their role as traitors with self-deception about their ambivalent position, they are eventually forced to acknowledge their position as one of self-defeat. Their ‘ethical betrayal’ (Parikh 2009) does therefore not lead to utopian fulfilment but to the traitors’ expiatory sacrifice as the only form of accountability and self-justification. In Wolf’s film antifascism as a tale of political redemption is thus revised and becomes a tale of necessary individual atonement.

NATO, Britain, France and the FRG: Nuclear Strategies and Forces for Europe, 1949-2000

This is vol. I of my two-volume study of the nuclear strategies/strategy preferences of NATO collectively, and individually of Britain, France, and West Germany in the Cold War. It shows that NATO strategy was a fragile compromise, and that these three countries, all within range of Soviet medium/intermediate range nuclear missiles and thus with less geostrategic difference than in previous military threat contexts, had wildly divergent strategies/preferences which cannot be explained merely by geography. It raises the question of what made them so different, addressed in Volume II "Nuclear Mentalities" (q.v.)

Western Containment Policies in the Cold War; The Yugoslav Case, 1948-1953

Containment, as conceived by the US government official George Kennan, was an aggressive attempt to cause the Soviet Cold War empire to disintegrate. This can is demonstrated by the case study of how the USA, Britain, and France tried to instrumentalise renegade Tito's Yugoslavia as a wedge to break up the cohesion of the Communist regimes within the Soviet sphere. They supported Tito against subversion and planned Soviet-orchestrated military attack from its neighbouring states; Western plans for the support of Yugoslavia included plans for a selective use of nuclear weapons.

‘Victory in a Nuclear War? A Comparison of NATO and WTO War Aims and Strategies’

Given the danger of the unbearable catastrophe of nuclear war, NATO in the mid-1950s abandoned any war aim of achieving victory in an all-out war with the Soviet Union or the Warsaw Treaty Organisation. Instead, it adopted the war aim of a cease-fire or war termination. By contrast, the WTO clung on to the war aim of victory - expressed even in terms of the survival of slightly more Soviet citizens than NATO citizens, after unprecedented losses of life in nuclear exchanges - until the mid-1980s when under Gorbachev the concept of victory in nuclear war was abandoned.

Surviving Objects

Surviving Objects (2012) is a devised multi-media practice-as-research performance based on extensive interviews conducted with my elderly mother and recorded on a hand-held device. Our conversations concern her experiences as a child refugee following violent deportation by the Soviet Army from Eastern Poland to Siberia (1941), and her subsequent route, via Persia, to a British-run refugee camp in Northern Rhodesia, where she remained for 6 years before arriving in the UK. In order to aid my mother’s reflections, our recorded conversations focus on the objects remaining from that period in her life – my ‘inheritance’. The material presence of this handful of objects is central to the ninety-minute performance. Surviving Objects constitutes my attempt to locate a theatrical form through which to root/re-route this engagement with my mother’s marginalised voice. The end-on performance haptically navigates themes of intimacy and failing memory – navigates, indeed, my constantly shifting relationship with my mother. It searches for new cross-medial pathways along which her experience, and my experience of her, can play-out. Surviving Objects involves: 1. live performance (two silent female actors handling/presenting my mother’s objects); 2. Film (two synchronously-playing, large-scale projections exploring the objects by means of a highly-magnifying macro lens); 3. Pre-recorded sound (my mother’s voice, taken from our recorded interviews, which were conducted in Polish, with my own verbal contribution meticulously editorially excised from those conversations); 4. My translation of her stories (appearing periodically as written text that ‘overlays’ - rather than sub- or surtitles - the projected imagery).

Isotype: design and contexts 1925–1971

The work in graphic communication carried out by Otto Neurath and his associates – now commonly known simply as Isotype – has been the subject of much interest in recent years. Conceived and developed in the 1920s as ‘the Vienna method of pictorial statistics’, this approach to designing information had from its inception the power to grow and spread internationally. Political developments in Europe played their part in its development, and production moved to the Netherlands (1934) and to England (1940), where the Isotype Institute continued to produce work until 1971. Bringing together the latest research, this book is the first comprehensive, detailed account of its subject. The Austrian, Dutch, and English years of Isotype are described here freshly and extensively. There are chapters on the notable extensions of Isotype to Soviet Russia, the USA, and Africa. Isotype work in film and in designing for children is fully documented and discussed. Between these main chapters the book presents interludes documenting Isotype production visually. Three appendices reprint key documents. In its international coverage and its extensions into the wider terrain of history, this book opens a new vista in graphic design.

Money laundering and the shadow economy in Kazakhstan

Purpose The purpose of this paper is to assess and highlight the approach taken towards the legal control of illicit money laundering taken in the Republic of Kazakhstan, in particular, the role played by an amnesty on the legalisation of illicit funds. This is particularly important as a basis for a wider discussion about the proper limits of the “criminalising” approaches commonly taken in anti-money laundering regulations. Design/methodology/approach The discussion and evaluation in the paper is based upon a conceptual analysis of the money laundering regime in Kazakhstan, in particular, the legal framework and policies of implementation adopted. Findings The paper demonstrates that the problems that are posed by the shadow economy in post-Soviet transition societies can make the blanket criminalisation of money laundering a self-defeating approach, unless accompanied by measures which allow for the achievement of “market-constituting” effects. Research limitations/implications The paper draws on experience and practice in one jurisdiction only (Kazakhstan); it also limits its focus to one particular example of a money laundering amnesty policy. Both of these limitations, therefore, suggest avenues for further comparative research. Originality/value The paper’s conclusions about the interactions between the shadow economies of transitional societies and the global anti-money laundering agenda have wider application in assessments of international law in this area.

The emergence of Agribusiness in Europe and the development of the Western European broiler chicken industry, 1945-73

This article presents new data on the emergence and growth of the leading Western European poultry industries after 1945. It shows that those countries where poultry output grew most quickly – especially the UK, Italy and Spain – were also the countries where the agricultural sectors adopted US technologies and US agribusiness organizational structures most vigorously. Elsewhere in Western Europe, poultry output grew much less quickly and the adoption of agribusiness structures lagged behind. By contrast, the poultry sector in the USSR was based on the Soviet collectivist system. This was the largest poultry sector in Europe, but also much less efficient. The article suggests therefore that the diffusion of agribusiness and the increase in poultry output were deeply entwined across Europe, with potentially important consequences for the different roles and impacts of agribusiness in Europe.

At the Front: common traitors in West German war films of the 1950s

The article looks at the figure of the traitor in 1950s’ West German films about World War II. It focuses on the representation of Wehrmacht soldiers who entertain relations with the Soviet enemy and are therefore seen to betray their nation. The discussion of three well-known films – 08/15, Der Arzt von Stalingrad, and Unruhige Nacht – shows these ‘traitors’ to have a highly ambivalent function: their narrative punishment is part of German post-war exculpation, yet they are also reminders of German guilt and ethical responsibility towards the ‘other’.

Entrepreneurship and cities: evidence from the post-communist world

While attributing urban success to more abundant supply of entrepreneurship, more recent studies on entrepreneurship have shifted their focus to examining cross-city variation in entrepreneurial activity. Despite a growing number of spatial-oriented studies of entrepreneurship worldwide to our best knowledge no empirical evidence exists on the determinants of cross-city variation in entrepreneurship in the context of the Former Soviet Union (FSU) states. Estrin and Mickiewicz (2010) show that transition economies generally exhibit lower rates of entrepreneurship than observed in most developed and developing market economies. This difference is even more pronounced for the FSU compared to Central and Eastern Europe. This paper investigates variation in entrepreneurial activity across FSU cities, attempting to bridge the city-level gap in spatial-oriented empirical research.

Rethinking the Russian Revolution as historical divide

This monograph is the product of a series of workshops held in the UK and the USA, the premise of which was to suggest that 1917 is the wrong departure point for a full analysis of the social and cultural particularities of the Soviet Union. Breaking away from the binary of ‘change and continuity’, however, we asked how the new and the old (tradition and modernity) came together to make the Soviet experience ‘across 1917’. Building on these workshops, we have gathered 15 scholars from America, Europe, Russia, and the Middle East to contribute to this edition. This volume examines, among other things, the social and cultural frameworks that helped determine Soviet perceptions of social duty, justice, and governance.

Etniska stereotyper på film : med utgångspunkt i amerikansk film med ryska motiv (2008-2011)

Filmmediet idag är den mest populära formen av masskultur. Med sin världstäckande genomslagskraft och sitt stereotypa porträtterande av verklighet, påverkar filmen världsåskådningen för människor runtom i världen. Ett brinnande ämne i amerikansk film har alltid varit Ryssland, på grund av de politiska motsättningarna och den historiska rivaliteten med USA. Studiens syfte är att undersöka hur Ryssland porträtteras i amerikanska filmer från perioden för presidenterna Dmitrij Medvedevs respektive Barack Obamas första mandatperiod. Frågeställningen för uppsatsen är: hur ser stereotypa föreställningar om Ryssland ut i amerikansk film 2008-2011? Trettiotal filmer med ryska motiv valdes ut för undersökningen och analyserades utifrån de visuella och sociala aspekterna. Resultatet visar på att det förekommer tre skikt av stereotyper om Ryssland: de eviga, som har existerat i hundratals år och spridits av resenärer; stereotyper från epoken för det kalla kriget; och stereotyper om det moderna Ryssland inspirerade av medias nyhetsrapporteringar.

Russian Arctic Ports : Problems with the development and management of tourist flows

The potential changes to the territory of the Russian Arctic open up unique possibilities for the development of tourism. More favourable transport opportunities along the Northern Sea Route (NSR) create opportunities for tourism development based on the utilisation of the extensive areas of sea shores and river basins. A major challenge for the Russian Arctic sea and river ports is their strong cargo transport orientation originated by natural resource extraction industries. A careful assessment of the prospects of current and future tourism development is presented here based on the development of regions located along the shores of the Arctic ocean (including Murmansk and Arkhangelsk oblast, Nenets Autonomous okrug (AO), Yamal-Nenets AO, Taymyr AO, Republic of Sakha, Chykotsky AO). An evaluation of the present development of tourism in maritime cities suggests that a considerable qualitative and quantitative increase of tourism activities organised by domestic tourism firms is made virtually impossible. There are several factors contributing to this. The previously established Soviet system of state support for the investments into the port facilities as well as the sea fleet were not effectively replaced by creation of new structures. The necessary investments for reconstruction could be contributed by the federal government but the priorities are not set towards the increased passenger transportation. Having in mind, increased environmental pressures in this highly sensitive area it is especially vital to establish a well-functioning monitoring and rescue system in the situation of ever increasing risks which come not only from the increased transports along the NSR, but also from the exploitation of the offshore oil and gas reserves in the Arctic seas. The capacity and knowledge established in Nordic countries (Norway, Finland) concerning cruise tourism should not be underestimated and the already functioning cooperation in Barents Region should expand towards this particular segment of the tourism industry. The current stage of economic development in Russia makes it clear that tourism development is not able to compete with the well-needed increase in the cargo transportation, which means that Russia’s fleet is going to be utilised by other industries. However, opening up this area to both local and international visitors could contribute to the economic prosperity of these remote areas and if carefully managed could sustain already existing maritime cities along the shores of the Arctic Ocean.
