Computer assisted communication in the education of the visually impaired

Discussion of the relationship between learning theory and CAL software is as relevant to the visually impaired as it is to other groups. There is, however, a more urgent issue, namely that of communication and the problems faced by the visually impaired in gaining access to the curriculum. It is estimated that 80% of school learning is dependent on visual material and consequently an impairment of vision constitutes a communication handicap and thus a barrier to education. The trends toward the education of the blind and partially sighted together, and toward integration into mainstream schools, have increased the complexity of meeting communication needs. At the same time developments in microtechnology have increased the range of possible aids and created opportunities for the exploitation of auditory and tactile, as well as visual, media. The purpose of this paper is to consider the educational implications of communication, to review significant technological developments and to discuss the facilities necessary to meet the communication needs of the visually impaired in different educational environments.

World tropical wood trade : Economic overview

Tropical wood is attracting global attention in the light of dwindling sources of industrial raw material supplies, increasing concern for conservation and growing requirements for huge investments. This study examines the changing character of the world hardwood trade, and the factors that will affect future supply, demand and price. It also considers the likely implications of recent large-scale attempts to grow tropical species for pulp, developments in microtechnology and biotechnology on wood, and the proposed international commodity agreement for tropical timber. The study emphasizes the need for huge investments on a global scale in afforestation and research to fully realize the potential of the tropical biomass.

Automated manufacturing—Why is it taking so long?

There are strong forces directed towards automated manufacturing with great potential for increases in productivity and efficiency. However, despite these forces, there are barriers preventing the rapid adoption of the new technologies. The author analyses these factors in relation to a study which aimed to identify market opportunities over the next decade in relation to the developments in microtechnology.
