<p class="Default">Broomrape, caused by <em>Orobanche cumana</em>, has affected sunflowers since the early 20<sup>th</sup> century in Eastern Europe. Currently, it limits sunflower oil production in Southern and Eastern Europe and in some areas of Asia, causing around 50% seed losses when susceptible hybrids are grown. Covered in this review are aspects such as: biological processes that are common to <em>Orobanche</em> spp. and/or particular to <em>O. cumana</em> in sunflower, genetic resistance and its mechanisms, races of the parasite identified in different countries throughout the time and their increasing virulence, and breeding for resistance to some herbicides as a novel control option. The main purpose is to present an updated and, as far as possible, complete picture of the way both the parasitic weed and its host crop have evolved in time, and how they co-exist in the current agriculture. Additionally, we propose a system for determining the races of the parasite that can be internationally adopted from now. In the context of minimal harmful effects on the environment, changing patterns of land use in farming systems, and global environment changes, the final goal of this work is to provide all those interested in parasites from field crops and their integrated management compiled information on the sunflower – <em>O. cumana</em> system as a case study.</p>

AbstractJascha Heifetz (1901–87) promoted a modern brand of musical eclecticism, recording, performing, and editing adaptations of folk and popular songs while remaining dedicated to the standard violin repertoire and the compositions of his contemporaries. This essay examines the complex influences of his displacement from Eastern Europe and assimilation to the culture of the United States on both the hybridity of his repertoire and the critical reception he received in his new home. It takes as its case study Heifetz's composition of the virtuosic showpiece “Hora Staccato,” based on a Romany violin performance he heard in Bucharest, and his later adaptation of the music into an American swing hit he titled “Hora Swing-cato.” Finally, the essay turns to the field of popular song to consider how two of the works Heifetz performed most frequently were adapted for New York Yiddish radio as Tin Pan Alley–style songs whose lyrics narrate the early twentieth-century immigrant experience. The performance and arrangement history of many of Heifetz's miniatures reveals the multivalent ways in which works in his repertoire, and for some listeners Heifetz himself, were reinterpreted, adapted, and assimilated into American culture.

The research on the “Intervision”, used as an empiric case study about the inter-cultural communication between its participants, consists of examining primary sources spread over several archives throughout Europe to collect structural and administrative data, making interviews with contemporary witnesses and evaluating statistics – with mainly the task to widen the perspective on a subject, that was formerly nation-focused or being described with a Western view only. As the preliminary steps of a basic study on the History of the Program Exchange in Eastern Europe during the Cold War, this research became an example, with which challenges one is confronted within an Media Archaeological task.

This chapter explores movement and circulation across the Mediterranean and seeks to contribute to a history of proto-nationalism in the Maghrib and the Middle East at a particular moment prior to World War I. The discussion is particularly concerned with the interface of two Mediterranean spaces: the Middle East (Egypt, Ottoman Empire) and North Africa (Morocco), where the latter is viewed as a case study where resistance movements sought external allies as a way of compensating for their internal weakness. Applying methods developed by Subaltern Studies, and linking macro-historical approaches, namely of a translocal movement in the Muslim Mediterranean, it explores how the Egypt-based society, al-Ittihad al-Maghribi, through its agent, Aref Taher, used the press as an instrument for political propaganda, promoting its Pan-Islamic programme and its goal of uniting North Africa.

This paper shows the principal features of merger control in selected transition economies of Central and Eastern Europe (CEE), namely Hungary, Romania and Slovenia, by applying case study methodology. The presented findings are based on the analysis of Hungarian, Romanian and Slovenian competition law and merger rulings reached by the Competition Offices of these countries. A substantial part of the conclusions is drawn from a sample of 42 merger applications processed by the Office of Economic Competition of Hungary between 1994 and 2000. The results of empirical analysis demonstrate the considerable flexibility of merger control in the studied countries, its orientation towards the future of domestic markets and a close link with industrial policy. The paper also highlights the areas of interdependence of competition policy and transition and argues that merger control in the studied CEE countries may be regarded as currently adequate to the requirements imposed by transition.

Immediately after the Second World War Sweden was struck by a wave of sightings of strange flying objects. In some cases these mass sightings resulted in panic, particularly after authorities failed to identify them. Decades later, these phenomena were interpreted by two members of the Swedish UFO movement, Erland Sandqvist and Gösta Rehn, as alien spaceships, or UFOs. Rehn argued that ‘[t]here is nothing so dramatic in the Swedish history of UFOs as this invasion of alien fly-things’ (Rehn 1969: 50). In this article the interpretation of such sightings proposed by these authors, namely that we are visited by extraterrestrials from outer space, is approached from the perspective of myth theory. According to this mythical theme, not only are we are not alone in the universe, but also the history of humankind has been shaped by encounters with more highly-evolved alien beings. In their modern day form, these kinds of ideas about aliens and UFOs originated in the United States. The reasoning of Sandqvist and Rehn exemplifies the localization process that took place as members of the Swedish UFO movement began to produce their own narratives about aliens and UFOs. The question I will address is: in what ways do these stories change in new contexts? Texts produced by the Swedish UFO movement are analyzed as a case study of this process.

This chapter uses two case studies to explore how historians study language movement and change through comparative historical linguistics. The first case study stands as a short chapter in the larger history of the expansion of Bantu languages across eastern, central, and southern Africa. It focuses on the expansion of proto-Kafue, ca. 950–1250, from a linguistic homeland in the middle Kafue River region to lands beyond the Lukanga swamps to the north and the Zambezi River to the south. This expansion was made possible by a dramatic reconfiguration of ties of kinship. The second case study explores linguistic evidence for ridicule along the Lozi-Botatwe frontier in the mid- to late 19th century. Significantly, the units and scales of language movement and change in precolonial periods rendered visible through comparative historical linguistics bring to our attention alternative approaches to language change and movement in contemporary Africa.
