Self-explanation in adaptive systems

The behaviour of self adaptive systems can be emergent. The difficulty in predicting the system's behaviour means that there is scope for the system to surprise its customers and its developers. Because its behaviour is emergent, a self-adaptive system needs to garner confidence in its customers and it needs to resolve any surprise on the part of the developer during testing and mainteinance. We believe that these two functions can only be achieved if a self-adaptive system is also capable of self-explanation. We argue a self-adaptive system's behaviour needs to be explained in terms of satisfaction of its requirements. Since self-adaptive system requirements may themselves be emergent, a means needs to be found to explain the current behaviour of the system and the reasons that brought that behaviour about. We propose the use of goal-based models during runtime to offer self-explanation of how a system is meeting its requirements, and why the means of meeting these were chosen. We discuss the results of early experiments in self-explanation, and set out future work. © 2012 C.E.S.A.M.E.S.

Design and designing:a critical introduction

Design and Designing provides a broad and critical understanding of what is essentially a practical subject. Designing today is less a craft and more a part of the knowledge economy. It's all about knowing how to acquire knowledge and how to apply it creatively. Design and Designing covers the design process, modelling and drawing, working with clients, production and consumption, sustainability, professional practice and design futures. Chapters are written by expert teachers and practitioners from around the globe, each presenting an accessible and engaging overview of their field of design. Every chapter is highly illustrated with a combination of images and information boxes, which extend or highlight key material. Each section concludes with a design project, a hands-on activity for the reader. Design and Designing covers the full spectrum of design types, from graphic communication to product design, from fashion to games design, setting every type in its aesthetic, ethical and social contexts. With this essential book, readers will learn from today's best practice and best thinking in design, they will develop a critical sense, and become the designers of tomorrow.

Self-explanation in adaptive systems based on runtime goal-based models

The behaviour of self adaptive systems can be emergent, which means that the system’s behaviour may be seen as unexpected by its customers and its developers. Therefore, a self-adaptive system needs to garner confidence in its customers and it also needs to resolve any surprise on the part of the developer during testing and maintenance. We believe that these two functions can only be achieved if a self-adaptive system is also capable of self-explanation. We argue a self-adaptive system’s behaviour needs to be explained in terms of satisfaction of its requirements. Since self-adaptive system requirements may themselves be emergent, we propose the use of goal-based requirements models at runtime to offer self-explanation of how a system is meeting its requirements. We demonstrate the analysis of run-time requirements models to yield a self-explanation codified in a domain specific language, and discuss possible future work.

Contesting labour internationalism:the "old" trapped in the "new" in Volkswagen’s South African plant

During the 1970s and 1980s, close linkages were established between unionists in Volkswagen's Uitenhage plant in South Africa and Wolfsburg in Germany. The ensuing relationship resulted in trade union internationalism and solidarity with South African workers in their struggle against apartheid. After the insertion of the South African plant into the global production networks of the company, a range of new pressures and challenges confronted the union in South Africa. This resulted in the mass dismissal in 2000. In an attempt to garner international support and solidarity, the dismissed workers tapped into existing structures with no success, illustrating the reconfiguration of trade union internationalism away from worker interests to those of the unions and company. © 2010 UALE.

Reflections on race in contemporary Ireland

Any reflection on the category "race" in the contemporary world is inevitably framed by the cumulative layers of meanings and practices attached to bodies and cultures over the previous centuries. If the idea of race resembles anything, it is a palimpsest,1with past interpretations leaking through to make the ink of the present run. Accordingly, I present some historical notes not as a distinct prelude to the "real" story, positing a rupture of past and present, but as the beginning of the story proper.
