Simulation der peristaltischen Förderung von Stückgütern als Schüttgut

Im Beitrag wird ein neuartiges Förderprinzip zur federnden Aufnahme und zum Transport von massenhaft anfallenden Paketstrukturen vorgestellt. Das Förderprinzip beruht auf einem flächigen Tragmittel in Form eines veränderbaren, elastischen Verbundes von kleinskaligen Fördermodulen. Das konzipierte Transportprinzip mit peristaltischen Eigenschaften soll entstehende Staus der Pakete schnell auflösen und eine dedizierte Steuerung von Teilmengen zulassen, um den erforderlichen Durchsatz innerhalb eines Materialflusssystems zu erreichen. Diese Lösung ermöglicht eine sinnvolle Verknüpfung von Wirkprinzipien der Schüttgut- und Stückgutförderung zur Aufnahme und Fortbewegung von Pakete als Schüttgut. Die Grundfunktionalität des Förderkonzepts wird durch die numerische Simulation auf Basis der Diskrete Elemente Methode sowie der Mehrkörpersimulation überprüft.

Efficient team actions: Outline of a theory of teams in sport

So far, social psychology in sport has preliminary focused on team cohesion, and many studies and meta analyses tried to demonstrate a relation between cohesiveness of a team and it's performance. How a team really co-operates and how the individual actions are integrated towards a team action is a question that has received relatively little attention in research. This may, at least in part, be due to a lack of a theoretical framework for collective actions, a dearth that has only recently begun to challenge sport psychologists. In this presentation a framework for a comprehensive theory of teams in sport is outlined and its potential to integrate the following presentations is put up for discussion. Based on a model developed by von Cranach, Ochsenbein and Valach (1986), teams are information processing organisms, and team actions need to be investigated on two levels: the individual team member and the group as an entity. Elements to be considered are the task, the social structure, the information processing structure and the execution structure. Obviously, different task require different social structures, communication and co-ordination. From a cognitivist point of view, internal representations (or mental models) guide the behaviour mainly in situations requiring quick reactions and adaptations, were deliberate or contingency planning are difficult. In sport teams, the collective representation contains the elements of the team situation, that is team task and team members, and of the team processes, that is communication and co-operation. Different meta-perspectives may be distinguished and bear a potential to explain the actions of efficient teams. Cranach, M. von, Ochsenbein, G., & Valach, L.

Cosmos and Colonialism. Alexander von Humboldt in Cultural Criticism

Alexander von Humboldt explored the Spanish Empire on the verge of its collapse (1799–1804). He is the most significant German travel writer and the most important mediator between Europe and the Americas of the nineteenth century. His works integrated knowledge from two dozen domains. Today, he is at the center of debates on imperial discourse, postcolonialism, and globalization. This collection of fifty essays brings together a range of responses, many presented here for the first time in English. Authors from Schiller, Chateaubriand, Sarmiento, and Nietzsche, to Robert Musil, Kurt Tucholsky, Ernst Bloch, and Alejo Carpentier paint the historical background. Essays by contemporary travel writers and recent critics outline the current controversies on Humboldt. The source materials collected here will be indispensable to scholars of German, French, and Latin and North American literature as well as cultural and postcolonial studies, history, art history, and the history of science.

"Fascinating Voids: Alexander von Humboldt and the Myth of Chimborazo"

When Alexander von Humboldt reached the village of Calpi in the Andes on 22 June 1802, he was greeted with reverence and enthusiasm. Triumphal arches adorned with cotton, cloth, and silver decorated his path. The natives performed a dance in festive dress. A singer praised the explorer's expedition, which had departed three years earlier from the Spanish port of La Coruña. Like Odysseus on the isle of the Phaeacians, the traveler listened to a local rhapsodist singing about his heroic deeds. Before his adventure ended, it had already spun a popular myth. This episode, which Humboldt recorded in his diary, occurred at a significant moment. One day later, the “Second Discoverer of America” rose to even greater fame on an excursion marking in more ways than one the climax of his enterprise. Humboldt set out to climb Chimborazo (6,310 m/20,702 ft.), the mountain then thought to be the highest in the world. He was accompanied by the French botanist Aimé Bonpland (1773–1858) and the Creole nobleman and future activist Carlos Montúfar (1780–1816), as well as native guides and assistants. They climbed to heights never reached before, setting a new record and catapulting Humboldt to fame on both continents.

Possible earthquake trigger for 6th century mass wasting deposit at Lake Ohrid (Macedonia/Albania)

Abstract. Lake Ohrid shared by the Republics of Albania and Macedonia is formed by a tectonically active graben within the south Balkans and suggested to be the oldest lake in Europe. Several studies have shown that the lake provides a valuable record of climatic and environmental changes and a distal tephrostratigraphic record of volcanic eruptions from Italy. Fault structures identified in seismic data demonstrate that sediments have also the potential to record tectonic activity in the region. Here, we provide an example of linking seismic and sedimentological information with tectonic activity and historical documents. Historical documents indicate that a major earthquake destroyed the city of Lychnidus (today: city of Ohrid) in the early 6th century AD. Multichannel seismic profiles, parametric sediment echosounder profiles, and a 10.08m long sediment record from the western part of the lake indicate a 2m thick mass wasting deposit, which is tentatively correlated with this earthquake. The mass wasting deposit is chronologically well constrained, as it directly overlays the AD472/AD 512 tephra. Moreover, radiocarbon dates and cross correlation with other sediment sequences with similar geochemical characteristics of the Holocene indicate that the mass wasting event took place prior to the onset of the Medieval Warm Period, and is attributed it to one of the known earthquakes in the region in the early 6th century AD.

Die historische und ekklesiologische Tiefe voll ausschöpfen. Respons zum Beitrag von Dorothea Sattler

This contribution responds to Dorothea Sattler’s thoughts about ecclesiology in an ecumenical context. First it describes in short the influence of Kurt Stalder’s theology for his generation of Old Catholic theologians, parish priests and lay people, as well as his contribution to the ecumenical theology in the 20th century. After that the author reacts on the three parts of Sattler’s contribution: on the Petrine function, on the apostolicity of ministry and on contemporary plurality and the unity of the church.

The scholarly networks of Albrecht von Haller and the Economic Society of Bern – a multi-level network analysis

Here, by the example of the transfer of cultivated plants in the context of the correspondence networks of Albrecht von Haller and the Economic Society, a multi-level network analysis is suggested. By a multi-level procedure, the chronological dynamics, the social structure, the spatial distribution and the functional networking are analyzed one after the other. These four levels of network analysis do not compete with each other but are mutually supporting. This aims at a deeper understanding of how these networks contributed to an international transfer of knowledge in the 18th century.

Ist eine wirksame psychosoziale Behandlung von Patienten mit Suchterkrankungen und komorbiden psychischen Störungen eine unmögliche Aufgabe?

Auf der Grundlage von Metaanalysen und umfassenden Überblicksarbeiten werden Schlussfolgerungen über eine wirksame psychosoziale Behandlung von Patienten mit einer Komorbidität von psychischen Störungen und Sucht (Doppeldiagnosen) gezogen. Dabei wird näher auf die Studienergebnisse zu schweren und zu leichten Formen von Doppeldiagnosen eingegangen. Die Heterogenität der Patienten-, Behandlungs-, Settings- und Ergebnismerkmale erschweren allgemeingültige Schlussfolgerungen über die Wirksamkeit psychosozialer Behandlungen. Integrative, gestufte Behandlungsprogramme, die störungsspezifische Interventionen kombinieren und motivierende Gesprächsführung, kognitiv-verhaltenstherapeutische Interventionen, suchtmittelreduzierende Interventionen wie Rückfallprävention oder Kontingenzmanagement und/oder Familieninterventionen enthalten, sind Kontrollgruppen (z.B. Wartegruppen, Standardbehandlungen) meistens, anderen aktiven Behandlungen (z.B. Psychoedukation) manchmal in den drei Ergebnisbereichen (Sucht, psychische Störung und Funktionsniveau) überlegen.

Luxurious Merovingian Textiles Excavated from Burials in the Saint Denis Basilica, France, 6th-7th century

A new examination of the textile fragments found in the Merovingian burials in the basilica of Saint Denis, near Paris, has recently underscored the diversity of fabrics used to make garments in which members of the royal court were buried. Among them, some woolens of fine quality had been dyed with indigotin. The most astonishing fibre found belongs to a mixed textile (not skin) with beaver fibers and wool. Silks contained shellfish purple and in one case kermes? Two dyestuffs associated with royalty and privilege. Along with this was large number of gold threads, probably produced locally and that were used in tablet-woven borders or for embroideries. In addition, several figured silks, of oriental origin, testify to the importance of this "foreign" material and the taste for textiles woven with complex techniques and probably what had originally had beautiful designs. Although none of these designs have been preserved and many colors have been greatly damaged, the technical characteristics of the remnants indicate proveniences as far as Byzantium, Sassanid Persia and the Chinese court. Such precious textiles show the high social status and political power of the Merovingian court, a testament to their ability to access such luxurious and costly textiles through diplomacy and/or trade with other powerful empires. The examination of these rare textiles along with other fine silks and luxury objects from the same period found in France expand our view of the fundamental role of textiles in the political sphere of this early period of European history.

New Philology and the Biogenetics of Texts

The discussion on the New Philology triggered by French and North American scholars in the last decade of the 20th century emphasized the material character of textual transmission inside and outside the written evidences of medieval manuscripts by downgrading the active role of the historical author. However, the reception of the ideas propagated by the New Philology adherents was rather divided. Some researchers considered it to be the result of an academic “crisis” (R.T. Pickens) or questioned its innovative status (K. Stackmann: “Neue Philologie?”); others appreciated the “new attitudes to the page” it had brought to mind (J. Bumke after R.H. and M.A, Rouse) or even saw a new era of the “powers of philology” evoked (H.-U. Gumbrecht). Besides the debates on the New Philology another concept of textual materiality strengthened in the last decade, maintaining that textual alterations somewhat relate to biogenetic mutations. In a matter of fact, phenomena such as genetic and textual variation, gene recombination and ‘contamination’ (the mixing of different exemplars in one manuscript text) share common features. The paper discusses to what extent the biogenetic concepts can be used for evaluating manifestations of textual production (as the approach of ‘critique génétique’ does) and of textual transmission (as the phylogenetic analysis of manuscript variation does). In this context yet the genealogical concept of stemmatology – the treelike representation of textual development abhorred by the New Philology adepts – might prove to be useful for describing the history of texts. The textual material to be analyzed will be drawn from the Parzival Project, which is currently preparing a new electronic edition of Wolfram von Eschenbach’s Parzival novel written shortly after 1200 and transmitted in numerous manuscripts up to the age of printing. Researches of the project have actually resulted in suggesting that the advanced knowledge of the manuscript transmission yields a more precise idea on the author’s own writing process.
