Instances and connectors : issues for a second generation process language

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

Permanent technological unemployment reconsidered

This thesis consists primarily of a critical review of recent literature on the subject of the employment effects of technological change. The analysis of this literature is derived from a 1942 article by Hans P. Neisser, directed against the orthodox denials of the possibility that technological progress could cause "permanent" or unreabsorbed displacement of labour. Arguments classified under one of the Say's Law, neoclassical, or wage fund schools are examined using the Neisser framework. As a secondary aspect, some elaboration is undertaken of the process by which uncompensated technological unemployment could arise. The main conclusion made is that, in agreement with Neisser's appraisal of the literature of his time, modern economic analysis is not able to refute the theoretical possibility that technological change can lead to the creation of a persistent pool of unemployed labour as outlined a by the Marxian schema
