    This work is supported by UK EPSRC grants GR/L34433 and GR/L32699Over the past decade a variety of process languages have been defined, used and evaluated. It is now possible to consider second generation languages based on this experience. Rather than develop a second generation wish list this position paper explores two issues: instances and connectors. Instances relate to the relationship between a process model as a description and the, possibly multiple, enacting instances which are created from it. Connectors refers to the issue of concurrency control and achieving a higher level of abstraction in how parts of a model interact. We believe that these issues are key to developing systems which can effectively support business processes, and that they have not received sufficient attention within the process modelling community. Through exploring these issues we also illustrate our approach to designing a second generation process language.Postprin

    "A Theoretical Perspective on Multi-level Systems in Europe: Constitutional Power and Partisan Conflict"

    types: ArticleThis article distinguishes three constitutionally defined categories of multi-level systems – confederations, federal arrangements and regionalized arrangements, which differ in whether their lower-level governments enjoy constitutional protection and whether we find a constitutional hierarchy between central and lower levels of government. We argue that the constitutional category a multi-level system belongs to systematically shapes first, the dominant mode of day-to-day intergovernmental coordination, second, the mode of formal competence (re)allocation; and third, the relative impact of party (in)congruence across central and lower-level governments on these coordination processes, respectively. The article then specifies the indicators used to test the hypotheses across the range of case studies. It finally shows how the multi-level systems covered in this special issue span the confederal – federal – regionalized spectrum and thus allow for an encompassing comparative assessment of multi-level dynamics and their long-term evolution.ESR
