In this case study in knowledge engineering and data mining, we implement a recognizer for two variations of thèbull ¯ag' technical charting heuristic and use this recognizer to discover trading rules on the NYSE Composite Index. Out-of-sample results indicate that these rules are effective. q 2002 Elsevier Science Ltd. All rights reserved.

Scenarios are often proposed as a means of managing innovation in use-centred design. Here we discuss ‘how’. Scenarios allow design spaces to be mapped, both marking and pushing the boundaries of those spaces, and charting paths through the conceptual terrain therein. They achieve this through facilitating two modes of design discourse (backward and forward linking), and mapping the granularity...

Grid cells, border cells, head-directions cells, and conjunctive correlates found in the Medial Entorhinal Cortex (MEC) indicate the presence of highly specialized neural circuits that process allocentric space. New technical advancements, as described by Tang et al. (2014) in this issue, offer an integrated approach to charting the function and organization of these circuits.
