Firms depend heavily on trade credit. In the years 1980-2004 about 60% of all inputs to production were purchased with a delayed payment. This paper provides evidence that trade credit connection plays signi cant role in the growth stability of customers by reducing the propagation of rm-level shocks from suppliers onto their customers. On average, customer experiences about 20% lower disruptio...

Coherent structures in the distribution of the Faraday rotation measure of extragalac-tic radio sources are isolated using wavelet transformation technique. A new algorithm of wavelet analysis for data points nonuniformly distributed on a sphere is developed and implemented. Signatures of the magnetic fields in the local (Orion) spiral arm, the Sagittarius and Carina arms, the synchrotron Loop ...

Distributed Processing Environments (DPE) or platforms are regarded as the future telecommunication architecture [1] on which distributed applications such as Multimedia Conferencing (MMC) services will operate. Using the DPE as target telecommunication platform, an important issue for MMC designers is the specification of generic MMC interfaces. This enables MMC users to access, in a distribut...

The Reference Model of Open Distributed Processing (RM-ODP) introduces the notion of an enterprise viewpoint and provides a minimum set of concepts for structuring enterprise language specifications. This paper extends the RM-ODP enterprise concepts by exploring how policy can be modelled within and between communities. A model for enterprise behaviour based on physical and social actions is pr...

This paper proposes design concepts that allow the conception, understanding and development of complex technical structures for open distributed systems. The proposed concepts are related to, and partially motivated by, the present work on Open Distributed Processing (ODP). As opposed to the current ODP approach, the concepts are aimed at supporting a design trajectory with several, related ab...

An additional challenge brought on by the age of the Internet is achieving reuse across distribution channels. I.e. one particular business process which used to serve the desktop (one channel) should now serve Intranet, Internet, WAP, desktop, atm (i.e., different distribution channels). As this challenge is often not addressed, or even not noticed, we tend to see the multiplication of similar...
