Abstract

This paper reports two experiments which compared the effectiveness of different methods for introducing blind and visually impaired people to the spatial layout of urban environments. In Experiment 1, 30 blind and visually impaired adults learned a long and complex route through an area of central Madrid (Spain) either by direct experience or by a combination of direct experience and a tactile map or a combination of direct experience and a verbal description of the area. Performance on measures of practical spatial knowledge and of representational spatial knowledge was significantly better in participants in the tactile map condition. In Experiment 2, participants learned a similar route in an area of Sheffield (Britain) using either just a tactile map of by direct experience. No significant difference was found between the two conditions using the same measures as in Experiment 1.

Abstract

Probes into the publishing and citing patterns of engineers and technologists of ISRO Satellite Centre, Bangalore as part of a lager information-behaviour study. Analyses publishing productivity of Indian space technologists for over a decade, examines various channels/sources in which they preferred publishing and the channels cited by them. Compares publishing in and citing from Indian with foreign sources. Discusses frequency distribution of number of papers published and number of references cited including self citations for all the publications as well as a separate distribution for Journals as sources of publication and citation to journal articles. Examines availability of the channels/sources used by authors in the primary library and tries to relate ‘use’ in library to publishing and citing. The most popular journals as sources used by Indian space technologists are identified. The source papers and citations of the most productive authors among the group are checked in SCI and results reported. Concludes that unlike other scientists and engineers; space technologists, by their very nature of work, are not much pressed by ‘publish or perish’ syndrome as only one fourth have ever published papers with an average of little over 2 papers per author. Even citations are not rich as 25% of papers had no citations. However, they had higher self citations than scientists in general and the channels used for citing were quite different from those used for publishing.
