Diese Dissertation stellt innovative Pricing- und Hedging-Modelle für eine breite Klasse von Versicherungsprodukten vor. Eine wichtige Neuerung im Hinblick auf die existierende Literatur ist dabei das Anwenden F-doppelt stochastischer Markovketten, was die Ausarbeitung der Formeln anhand stochastischer Intensitätsprozesse ermöglicht. Für die Prämienbestimmung für Arbeitslosigkeitsversicherungsprodukte werden die Intensitätsprozesse durch mikro- und makroökonomische stochastische Kovariablenprozesse generiert, um Einflüsse und Abhängigkeitsstrukturen innerhalb von Arbeitsmärkten zu untersuchen. Als Preisregel wird die „Real-World“-Preisformel des Benchmark-Ansatzes gewählt. Für die Bestimmung optimaler Hedgingstrategien werden quadratische Hedging-Methoden auf eine breite Klasse von Versicherungsprodukten, u.a. Lebensversicherungsprodukten, angewandt. Die Lösungen werden dabei anhand der Galtchouk-Kunita-Watanabe-Zerlegung jeweiligen der Schadenprozesse bestimmt.
On 18 April 1947, British forces set off the largest non-nuclear explosion in history. The target was a small island in the North Sea, fifty miles off the German coast, which for generations had stood as a symbol of Anglo-German conflict: Heligoland. A long tradition of rivalry was to come to an end here, in the ruins of Hitler's island fortress. Pressed as to why it was not prepared to give Heligoland back, the British government declared that the island represented everything that was wrong with the Germans: 'If any tradition was worth breaking, and if any sentiment was worth changing, then the German sentiment about Heligoland was such a one'. Drawing on a wide range of archival material, Jan Ruger explores how Britain and Germany have collided and collaborated in this North Sea enclave. For much of the nineteenth century, this was Britain's smallest colony, an inconvenient and notoriously discontented outpost at the edge of Europe. Situated at the fault line between imperial and national histories, the island became a metaphor for Anglo-German rivalry once Germany had acquired it in 1890. Turned into a naval stronghold under the Kaiser and again under Hitler, it was fought over in both world wars. Heavy bombardment by the Allies reduced it to ruins, until the Royal Navy re-took it in May 1945. Returned to West Germany in 1952, it became a showpiece of reconciliation, but one that continues to wear the scars of the twentieth century. Tracing this rich history of contact and conflict from the Napoleonic Wars to the Cold War, Heligoland brings to life a fascinating microcosm of the Anglo-German relationship. For generations this cliff-bound island expressed a German will to bully and battle Britain; and it mirrored a British determination to prevent Germany from establishing hegemony on the Continent. Caught in between were the Heligolanders and those involved with them: spies and smugglers, poets and painters, sailors and soldiers. Far more than just the history of a small island in the North Sea, this is the compelling story of a relationship which has defined modern Europe.
Petermann's Maps focuses on the maps published in the famous German journal Petermanns Geographische Mitteilungen. This journal, which still exists today, greatly influenced the development of scientific geography and cartography in Germany in the nineteenth century. Numerous articles have been published by recognized experts in this field, along with a multitude of illustrations, showing maps, prints and photographs. The journal developed into an important publication, setting the standard in the history of the great expeditions and discoveries, and European colonial matters. Petermann's Maps contains a bibliography of over 3400 maps, the complete series of maps published in Petermanns Geographische Mitteilungen between the year of its foundation, 1855, to the end of the Second World War. Besides the bibliography 160 of the most attractive geographical and thematic coloured maps are included in Petermann's Maps. These maps can also be viewed on the CD-ROM accompanying the book.An extensive introduction precedes the cartobibliography proper, placing Petermanns Geographische Mitteilungen in its historical context. The introduction describes the history of geography from the eighteenth century onwards, outlining the development of the study of the science of cartography in Germany. The major role the founder of the journal, Augustus Petermann (1822-1878), and the publishing house Justus Perthes in Gotha played in these developments is discussed at length.
