Business models are not typically doomed to remain as they are; rather, they may contain a variety of options to be changed or extended. Nevertheless, current approaches for business model representation cannot handle such options, because no appropriate modeling constructs are available. This substantially inhibits the qualitative consideration of options in business model design. Also, it inhibits the integration of options into subsequent quantitative analysis. Our contributions in this context are twofold: at a 'macro-level', we combine business model representations with real options theory from finance. At a 'micro-level', we extend one widely established and applied business model representation, namely e3-value, for handling real options. We develop the graphical notation necessary for option modeling and a corresponding extension of the formal e3-value ontology. Finally, we illustrate in a case study how the proposed extensions can support options reasoning and also serve as a basis for the correct financial analysis of a business model. 45th Hawaii International Conference on System Sciences978-0-7695-4525-7/12 $26.00

Recent work with young adults has shown that, depending on study context access, selective memory retrieval can both impair and improve recall of other memories (Bäuml & Samenieh, 2010). Here, we investigated the 2 opposing effects of selective retrieval in older age. In Experiment 1, we examined 64 younger (20-35 years) and 64 older participants (above 60 years), and manipulated study context access using list-method directed forgetting. Whereas both age groups showed a detrimental effect of selective retrieval on to-be-remembered items, only younger but not older adults showed a beneficial effect on to-be-forgotten items. In Experiment 2, we examined 112 participants from a relatively wide age range (40-85 years), and manipulated study context access by varying the retention interval between study and test. Overall, a detrimental effect of selective retrieval arose when the retention interval was relatively short, but a beneficial effect when the retention interval was prolonged. Critically, the size of the beneficial but not the detrimental effect of retrieval decreased with age and this age-related decline was mediated by individuals' working memory capacity, as measured by the complex operation span task. Together, the results suggest an age-related dissociation in retrieval dynamics, indicating an earlier decline of the beneficial than the detrimental effect of selective retrieval with older age.

The series EmotionCultures is a collection of works centered around current questions raised in interdisciplinary and innovative research on emotions. At the core are empirical studies from Social and Cultural Anthropology that analyze processes of social and cultural modeling of emotions -always in close theoretical as well as methodological connection to various other disciplines. Key topics concern the generation of emotional codes in interaction with socio-cultural, historical, and political structures. Thus, this series ranges from the socialization of emotions in childhood to their transformation with increasing age. It incorporates reconfigurations of emotions against the backdrop of changing life conditions. Furthermore, a particular focus rests upon the emotional dynamics inherent to processes of migration, globalization, and transnationalization.The series is edited by Birgitt Röttger-Rössler and Anita von Poser.
