Maximising the language and learning link in computer learning environments

In studies on the implementation and educational uses of computers there are reports of changes in students' behaviour as a result of working with computers (Rowe, 1993; Crook, 1994). Social, collaborative and dialogic exchanges have been observed as students engage in tasks around computers. This research provides evidence that the computer is a social facilitator in the sense that it provides opportunities for collaboration, group work and interaction which fosters cognitive change (Wild, 1995).
This article recognises the social role of the computer, and supports the view that computers can be used to facilitate learning through language. There is growing awareness that if we are to realise the full potential of computers in education, consideration must be given to their role as catalysts in the learning process, rather than technological tools (Hawkridge, 1990). Computer assisted learning has progressed through many phases, and through investigation of underlying theoretical frameworks it is possible to recognise the change of focus from individual accounts of learning to social perspectives.
Theoretical frameworks which emphasise the social dimensions of learning (Vygotsky, 1978) legitimise the link between computers, language use and learning and indicate that computers must be integrated into the social life of classrooms if their pedagogical benefits are to be realised.     

Longitudinal study of preadolescent sport self-concept and performance: reciprocal effects and causal ordering

Do preadolescent sport self-concepts influence subsequent sport performance? Longitudinal data (Grades 3, 4, and 6) for young boys and girls (N= 1,135; mean age = 9.67) were used to test reciprocal effects model (REM) predictions that sport self-concept is both a cause and a consequence of sport accomplishments. Controlling prior sport performance (performance-based measures and teacher assessments), prior sport self-concept had positive effects on subsequent sport performance in both Grade 4 and Grade 6 and for both boys and girls. Coupled with previous REM studies of adolescents in the academic domain, this first test for preadolescents in the sport domain supports the generalizability of REM predictions over gender, self-concept domain, preadolescent ages, and the transition from primary to secondary school.     

Resource constraints as triggers of radical innovation: Longitudinal evidence from the manufacturing sector

Despite the significant role of radical innovation as a driver of firm growth and performance, the consequences of resource constraints for radical innovation outcomes remain unknown. Our paper addresses this gap. We combine arguments from entrepreneurship theory and the theory of recombinative innovation to construct an overarching theoretical framework that argues why resource constraints can promote, rather than impede, radical innovation. We then build hypotheses on two specific resource constraints, knowledge and financial, and test these by a lagged-variable random-effects Tobit model with longitudinal data from an exceptionally large and detailed innovation survey. Controlling for absorptive capacity, firm age, and firm growth, we find full support for the hypothesis that knowledge constraints spur radical innovation and partial support for the hypothesis that financial constraints spur radical innovation. We discuss the theoretical significance of these findings and point to managerial implications and paths for future research.     

The development of assistive dementia technology that accounts for the values of those affected by its use

Developing technology that accounts for values has been achieved in many areas, including security, gaming, finance, engineering, and many more. The main methodological approach has been that of value sensitive design. But most of the work to date has been on the first of its three stages. The focus of this article is on advances related to its second stage, empirical investigation, and in particular the impact of contextual understanding in that stage. Although lessons can be learnt from other domains, the specific context of dementia means that there are nuances to understanding values, including justice and autonomy, that differ from other areas. The integration of value considerations in the development of assistive technology in dementia is explored in two broad categories: the traditional and ongoing need for fixed decision support, and adaptable decision support technologies. For fixed decision support the A&D Benchmark is particularly useful in design. But for adaptable technologies, that benchmark requires further development, including consideration of the values of additional stakeholders, such as the general public.
