This short paper is intended to highlight an interesting psychological phenomenon affecting the accuracy of mental models. It occurs when two events happen as expected by an operator but for reasons that are actually not understood. In other words, a mental model of a problem is erroneously taken to be valid as a result of a mere co-occurrence. We discuss(More)
Classically, humans have been perceived as a source of faults in systems. Modern ergonomic views are promoting a somewhat different idea according to which humans are a factor of safety in unexpected situations. The safety of a system cannot be achieved without taking into account these two sides of cognition which compose what is called cognitive(More)
Supporting independent living for the ageing population in later life is an often-cited application area for ubiquitous computing. Telecare services such as remote monitoring systems are now coming onto the consumer market but there is little knowledge of the impact these technologies may have on relationships between family members and older relatives. We(More)
Dependability frequently focuses on approaches such as rigorous design and fault tolerance. A final software product is strongly influenced by the people who created it. Large variations in individual performance in software development have been observed. Some form of innate programming ability might account for some of the differences. The influence of(More)
This report describes a proof-of-concept study demonstrating the analysis of dynamic coalition policies and structures by means of a tool based on a formal abstract model. The study suggests that such models may be valuable tools in designing for dynamic, adaptive behaviour in coalitions. Previous research has used formal modelling as a way of gaining(More)
The prevalence of location-informing devices such as smart phones brings a lot of benefits, such as the ability to find the right services nearby. Nonetheless, there are also concerns that such devices might infringe our privacy and breach security. This paper discusses both viewpoints by outlining how location information might be obtained, what the(More)
In this paper we discuss the current state of our work regarding the development and planned in-situ testing of a computer-based system to enhance community relations through the Neighbourhood Watch scheme. The system is intended for use in a community to help the residents interact with each other more easily and to encourage the reporting of suspicious(More)

The Fauna Europaea project comprises about(More)
This article outlines the ongoing work in relation to personality and programming ability. Previous work by the author focussed on code review and personality, discovering that certain personality factors were correlated with performance on a code review task. The current work is more concerned with code comprehension ability. In addition to the personality(More)
