We describe a novel query interface allowing the construction and manipulation of Description Logic expressions. The construction process is driven by the content of a conceptual model, guiding the user towards appropriate choices and providing a lucid interface.

The dataflow language Lucid applies concepts from intensional logic to declarative ISWIM expressions which are intensionalised relative to the dimension of time, thus introducing the notion of an expression’s history. Lucian, a language derived from Lucid, embeds dataflow into object-orientation allowing the intensionalisation of objects. Lucian introduces the notion of a declarative intensiona...

In the paper we describe how Lucid can be extended to allow user-defined functions and scope conventions, i.e., conventions for limiting the range or scope of the validity of definitions. The new constructs added (they are called clauses) are similar in form to the blocks and procedure declarations of Algol-like languages, but are nevertheless strictly non-imperative, because a clause is actual...

One might pose the question: since adults with dyslexia typically have problems with reading, writing and spelling, why nor simply measure those skills in order to identify the individuals who have dyslexia? The problems with this approach are (a) the differences in literacy skills between dyslexic and non-dyslexic persons are largely quantitative rather than qualitative, and (b) the developmen...

The descriptions of the signs, symptoms and diagnosis, the preand post-operative treatment are lucid and written in a fluent style. On reading the book one gets the impression that the main attentio...

The term “public sphere” conjures in the mind an image of place, whether we see the coffee houses, salons, and debating clubs of seventeent...

Delayed post-hypoxic leukoencephalopathy is a rare clinical phenomenon usually observed in a small number of carbon monoxide poisoning survivors. A similar phenomenon is reported here in a patient who successfully recovered from a large overdose of diazepam and methadone, but then abruptly declined 3 weeks after the initial event. Magnetic resnance revealed confluent white matter hyperintensity...
