Goal modeling languages, such as i* and the Goal-oriented Requirements Language (GRL), capture and analyze high-level goals and their relationships with lower level goals and tasks. However, in such models, the rationalization behind these goals and tasks and the selection of alternatives are usually left implicit. To better integrate goal models and their rationalization, we develop the Ration...

This paper adopted a critical perspective to examine IS-enabled IT customer services rationalization project in a UK University context. Informed by Foucaultian framework of rationality/power and ethics the paper seeks to demonstrate how individuals deploy their critical moral reflection to enact ‘the care of the self’ in living with the consequences of IS-enabled services process change. The s...

— We prove a quantitative version of a result of Furstenberg [20] and Deligne [13] stating that the the diagonal of a multivariate algebraic power series with coefficients in a field of positive characteristic is algebraic. As a consequence, we obtain that for every prime p the reduction modulo p of the diagonal of a multivariate algebraic power series f with integer coefficients is an algebrai...

Existing belief merging operators take advantage of all the models from the bases, including those contradicting the integrity constraints. In this paper, we show that this is not suited to every merging scenario. We study the case when the bases are ”rationalized” with respect to the integrity constraints during the merging process. We define in formal terms several independence conditions for...

There are several examples of heuristic rules first proposed from empirical observation, which eventually earned physicochemical validity after the fundamental derivation of a posteriori. This may be the case of Sherwood’s plot – for which a sound rationalization from first principles, entailing enthalpy and mass balances, is provided here; it applies to (fine) chemicals undergoing concentr...
