The mirroring hypothesis suggests a correspondence between product, firm and industry architecture, however, empirical support to date has been mixed. Drawing upon an inductive study of the UK pensions industry, we break new ground by investigating extent which architectures correspond in face changing institutional dynamics – most notably dynamic regulatory change. In considering periods both ...

Exceptions are an important feature of modern programming languages, but their compilation has traditionally been viewed as an advanced topic. In this article we show that the basic method of compiling exceptions using stack unwinding can be explained and verified both simply and precisely, using elementary functional programming techniques. In particular, we develop a compiler for a small lang...

Models of argumentation often take a given set of rules or conditionals as a starting point. Arguments to support or attack a position are then built from these rules. In this paper, an attempt is made to develop constraints on rules and their exceptions in such a way that they correspond exactly to arguments that successfully support their conclusions. The constraints take the form of properti...

We demonstrate that the Python programming language is not signal-safe, due to Python’s support for raising exceptions from signal handlers. We examine the approaches that various languages have used when dealing with the combination of asynchrony and exception handling, and propose a modification of the Python language that restores signal safety.
