In this paper we propose a new approach to User Model Acquisition (UMA) which has two important features. It doesn’t assume that users always have a well-defined idea of what they are looking for, and it is ontology-based, i.e., we deal with concepts instead of keywords to formulate queries.

The rise of cloud computing is radically changing the way enterprises manage their information technology (IT) assets. Considering the benefits of cloud computing to the information technology sector, we present a review of current research initiatives and applications of the cloud computing paradigm related to product design and manufacturing. In particular, we focus on exploring the potential...

Secretory granules are specialized intracellular organelles that serve as a storage pool for selected secretory products. The exocytosis of secretory granules is markedly amplified under physiologically stimulated conditions. While granules have been recognized as post-Golgi carriers for almost 40 years, the molecular mechanisms involved in their formation from the trans-Golgi network are only ...

The academic field of information systems has developed because organizations use a specialized body of knowledge about information and communications systems. Teaching and research support these organization needs. The field may be defined in terms of observed information systems in organizations and also in terms of the function or field of activity for system planning, development, managemen...

When real balances have even a very small productive role, contemporaneous and forwardlooking Taylor-Wicksell rules can induce ubiquitous multiplicities of equilibria and lead to consequences that are unintended by policymakers. This raises the issue of whether it is possible to anchor and stabilize the economy through backward-looking rules. We show that the standard uniqueness results that ar...

This paper contributes to the address of two questions emphasized in the recent literature on models of the role of monetary policy in the economy. The …rst concerns the consistency of the New Keynesian sticky price model with the high degree of persistence in in‡ation. The second concerns the possibility that perceived di¤erences in the behavioral relationship between in‡ation, interest rates,...
