An argumentation system consists of a set of interacting arguments and a semantics for evaluating them. This paper proposes a new family of semantics which rank-orders arguments from the most acceptable to the weakest one(s). The new semantics enjoy two other main features: i) an attack weakens its target but does not kill it, ii) the number of attackers has a great impact on the acceptability ...

Sowohl die kausale (Causation) als auch die effektuative Entscheidungslogik (Effectuation) werden von Entrepreneuren in verschiedenen Entscheidungssituationen angewandt. Instrumente zur Erfassung, Analyse und Bewertung von kausalem bzw. effektuativem Entscheidungsverhalten sind jedoch unterrepräsentiert. Obgleich bereits agentenbasierte Simulationsansätze zur Erforschung von Causation und Effec...

For L&R this distinction is represented in lexical conceptual structure. In this paper I argue that representing this distinction in the syntax, rather than in the lexicon, allows a crosslinguistically more satisfying theory of ...

We focus on the coupling of two existing and calibrated single currency Libor models into a joint Libor model that allows for pricing of multiple currency based structured interest rate products. Our main contribution is twofold: On the one hand we provide a method for synthesizing two local currency based correlation structures into a correctly defined joint correlation structure that describe...
