Ordnance Survey Maps: Their Meaning and Use

Accuracy of Heights from Ordnance Survey Maps

1) Spot heights at summits have an accuracy of about ±3.3m at all map scales, in agreement with the published figure. 2) Levelled heights from old 6-inch maps can be a few metres below the summit but are unlikely to be more than a few tenths of a metre higher. 3) The accuracy of old and new 1:50k maps is similar, but where heights have changed the old height has a tendency to be too low. 4) Spo...

When objects lose their meaning: what happens to their use?

The 8 patients involved in this study were impaired on tests assessing knowledge of objects and on the demonstration of their use. The patients' success in object use was significantly correlated with their knowledge about the objects, providing further evidence that conceptual knowledge plays a key role in object use. Having a recipient present improved performance in the moderately impaired p...

Recently, a large number of such indirect, or "implicit," measures have emerged. We review research that has utilized these measures across several domains, including attitudes, self-esteem, and stereotypes, and discuss their predict...

Autofunctors and Their Meaning

In the present paper, the meanings of this notion are analysed in the light of a proposed structural-phenomenological interpretation of the theory of categories (Draganescu 2000). The autofunctor may become important for phenomenological categories. It represents an informational and physical process, not only a mathematical notion. It...
