In this report the widely-held view that house dust mites benefit from fungal contamination of the dietary substratum is re-examined. The performance of Dermatophagoides pteronyssinus (Acari: Pyroglyphidae) is documented over two successive generations in the presence or absence of the xerophilic fungus Aspergillus penicillioides (Hyphomycetales:(More)
This paper shows the results of a detailed skills audit and skills gap analysis among some 380 people from 38 small or medium sized companies in the South East of England, UK. Most participants reported that their own abilities were consistent with the needs of their jobs in most areas of basic software use (word processing, database use, spreadsheet use(More)
AIM The aim of this paper is to stimulate interest in the practical classroom application of concept mapping strategies as an approach that teachers can easily use to enhance collaborative learning. BACKGROUND Concept mapping has been developed as a tool to support meaningful learning. However, much of the research literature fails to explain how concept(More)
Testing real-time systems under probabilistically distributed stimuli helps uncover faults that elude other forms of testing. In such testing, it is highly desirable that failures be detected rapidly, so that relevant internal states and traces can be collected. This paper describes a real-time validator which monitors inputs and outputs to the system under(More)
This project uses concept mapping and interview techniques to track changes in knowledge and understanding among students and their supervisors in the course of full-time research towards a PhD. The on-going work measures both cognitive change in the specific subjects that are the topic for research and in the understanding of the process of PhD level(More)

This article develops the concept-mapping method as a tool for enhancing teaching quality in higher education. In particular, it describes how concept mapping can be used to transform abstract knowledge and understanding into concrete visual representations that are amenable to comparison and measurement. The article describes four important uses of the(More)
This communication demonstrates unequivocally that the fungi associated with house dust mites do not contribute to mite allergenicity. The evidence is twofold: first, larval mites which lack fungi have allergen profiles indistinguishable from fungus-bearing adult mites. Second, the allergen profile of experimentally-derived fungus-free adult mites and mites(More)
