An international structure for library education

The training of information personnel at the middle level in Africa is discussed. The data were derived from the latest issues of the prospectuses of the library schools at the University of Ibadan and Botswana as well as a questionnaire designed to ascertain the characteristics of the trainees in both institutions. The study reveals that the curricula of both schools extend beyond preparing trainees for the techniques and processes of a library. The trainees in both schools have sufficient educational background and library/information work experience to enable them to manage the many one-man libraries scattered all over Africa effectively, after undergoing the diploma training. It is recommended that an amalgam of the curricula of both schools can be made the standard curriculum for any institution involved in a training programme for information personnel at this level.     

Design issues for human-machine platform interface in cable-based parallel manipulators for physiotherapy applications

We outline problems and potential solutions for feasible human-machine interfaces using cable-based parallel manipulators for physiotherapy applications. From an engineering perspective, we discuss the design constraints related to acceptance by patients and physiotherapist users. To date, most designs have focused on mobile platforms that are designed to be operated as an end-effector connected to human limbs for direct patient interaction. Some specific examples are illustrated from the authors＇ experience with prototypes available at Laboratory of Robotics and Mechatronics （LARM）, Italy.     

Making Sense of Number Words and Arabic Digits: Does Order Count More?

The ability to choose the larger between two numbers reflects a mature understanding of the magnitude associated with numerical symbols. The present study explores how the knowledge of the number sequence and memory capacity (verbal and visuospatial) relate to number comparison skills while controlling for cardinal knowledge. Preschool children’s (N = 140, M_{age-in-months} = 58.9, range = 41–75) knowledge of the directional property of the counting list as well as the spatial mapping of digits on the visual line were assessed. The ability to order digits on the visual line mediated the relation between memory capacity and number comparison skills while controlling for cardinal knowledge. Beyond cardinality, the knowledge of the (spatial) order of numbers marks the understanding of the magnitude associated with numbers.     

From splendid isolation to crossed boundaries? The futures of teacher education in the light of activity theory

Many policy documents addressing the future of teacher education do not take into account the fundamental unpredictability of the future, nor the opposing forces that will try to influence that future. Through the analysis of 48 scenario documents on the future of education or teacher education, we identified a set of unpredictable key factors that have to be taken into account when addressing the future of teacher education. We also identified four main futures that may lie ahead for teacher education. We analyzed these four scenarios using the concepts of activity systems, boundary objects, and boundary crossing. This revealed that the extent to which activity systems are open to boundary crossing and are willing to remove institutional boundaries will largely define the future that lies ahead for teacher education. Future scenarios in themselves can play a role as boundary objects that facilitate the dialogue and boundary crossing between these activity systems.
