This paper purports to analyze a hospital's adoption of both product and process innovation as a quantal choice. The impacts of this decision on physicians, while depending on institutions that differ between the US and continental Europe, are shown to feed back to the hospital, influencing the profitability of the innovation. Recent changes of hospital finance give rise to...

We use data from the German Socio-Economic Panel to investigate how individual happiness is affected by unemployment. Unemployment has a large and negative effect even after controlling for individual specific fixed effects. Nonparticipation, in contrast, is much less harmful to happiness. Further, we decompose the total well-being costs of unemployment and find that well above three...

Many applications require the capability to define and manipulate a collection of related objects as a single unit. Object-oriented database models and systems usually provide the concept of composite object for that purpose. The concept of context that we propose here provides another, more general, way to view and manipulate collections of objects. We compare the two concepts both...

Most distributed systems are built on top of a message exchange infrastructure. Processes coordinate their execution by exchanging messages which are interpreted according to a pre-established set of protocols. We present in this paper a novel way of communicating which does not require the preconfiguration of protocol entities. The host initiating the communication has the ability...

In this document we give an overview of the CO-OPN/1.5 (Concurrent Object-Oriented Petri Nets) specification language and describe the features of each tool provided in the SANDS/1.5 (Structured Algebraic Net Development System) development environment. The CO-OPN/1.5 language is a specification language devised to support the development of large concurrent systems. The underlying...

Mobile software agents require a distributed execution environment in which they can command the use of many resources like memory, CPU time and bandwidth. While current research seems to concentrate on roaming agents at the application level and tries to define suitable high–level environments, we think that such an execution environment must be rooted at a very low-level. We argue...
