Programmers often code up asynchronous message-passing systems as communicating finite-state actors. An actor in some state listens for messages, responds to those messages, and transitions to another state. Most of these systems allow messages to carry actor addresses. This paper presents a kernel language for implementing and specifying such systems. A specification consists of finite-state m...

extended abstract 1. introduction iran's islamic revolution that was initially started after the coup of 1932 (1955 ad), during the 25 years until 1979, in terms of formation, persistence, and practical and ideological leadership took a direction that major revolutions of 19th and 20th centuries fail to take. these revolutions believed that any change out of their framework was simply impossibl...

Since the publication of Between Facts and Norms, it appears to have gone largely unremarked by crit‐ ical theorists that Habermas has wholly abandoned the neo‐Parsonian systems‐theoretic account of so‐ cial systems developed in his middle period. In this paper, I argue not only that Habermas has developed a new vocabulary and theoretical structure for dealing with social systems ...

Twenty 9to 12-year-olds with specific language impairment (SLI) were compared with 18 agematched controls on auditory discrimination tasks, using a three-interval, two-alternative forced-choice format. The first task used minimal word pairs in silence and in noise. Nonspeech tasks involved discriminating direction of frequency glides and had two versions: (a) the glide moved from 500 to 1500 Hz...

ed, and concrete systems. Differentiating abstracted systems from conceptual systems by suggesting that the former are more likely to have empirically determined components, Miller argues that the unification of the sciences would proceed more rapidly if all of the sciences were oriented to either con115 Easton, op. cit., pp. 65-66. 11o Ibid., pp. 27-30, 33-34, 44-45, 64-66. ur See Alfred North...

In honouring certain achievements of Professor Felix Geyer, this paper explores the idea of ‘Dandyism’. It reminds us that whereas, in the eighteenth-century, a ‘fop’ was a figure identified with femininity and folly through ‘over-dressing'; the dandy originally exemplified elegance and self-restraint. Dandyism therefore epitomised a more masculine balance between fastidiousness and casualness....

Flood conditions present dangers for canoe camping, with the highest risk injury or death related to water submersion of paddlers. Other hazards can exist at high stages as well. This essay discusses preparation risks associated travel during record flood in Alabama’s Mobile-Tensaw River Delta. It examines unique aspects paddling through submerged forests, route detours necessitated by flooding...

ions over hole variables, hole lling simply boils down to (multiple) -reduction. So, in our running example we get ( h: x:x( h x)y)( x:x)! x:x( ( x:x) x)y. In the case of composition, the rewrite relation involves some shifting of abstractions. For example, let C x:2 and D x( y:2) be two -contexts. Then the composition of the two, here denoted by C D, results in the context x:x( y:2). Note that...

Max Weber’s concept of routinization offers a useful framework for understanding the relationship between political economy and the organization of religious movements. Here, we apply this concept to a comparison of Hopewell and Mississippian, two of the most important religious movements in the precolonial Eastern Woodlands. We focus on two archaeological contexts in particular—Mound 25 at the...

locations, e.g. , g for lg and b for lb . To formalize our analysis, we need to introduce a bit more notation. Given a program P , let VarP be the set of variables occurring in P . Let VarO be the set of variables labelling possible object creation points occurring in P . Let d HvalP be the set of abstract heap values of P . Let Pfin be the nite power-set constructor, and let mt(a) denote the m...
