Appropriation Infrastructure: Mediating Appropriation and Production Work

End User Development offers technological flexibility to encourage the appropriation of software applications within specific contexts of use. Appropriation needs to be understood as a phenomenon of many collaborative and creative activities. To support appropriation, we propose integrating communication infrastructure into software application that follows an“easy-to-collaborate”-principle. Su...

Indeed, if an inventor can appropriate the full surplus from his invention the first best will be obtained. We observe that while full appropriation is sufficient for efficiency, it is not nec...

Value Appropriation and Competition Revisited

One of the foundational questions underlying strategy research relates to identifying characteristics of economic situations that enable value appropriation by firms.

From Boulez to ballads: Training IRCAM's Score follower

This paper describes our attempt to make the Hidden Markov Model (HMM) score following system developed at Ircam sensible to past experiences in order to obtain better audio to score real-time alignment for musical applications. A new observation modeling based on Gaussian Mixture Models is developed which is trainable using a learning algorithm we call automatic discriminative training. The no...
