Issues of Digital Ecosystems Approach to Biological Ecosystem Simulation Model Fit Optimization

This study examines the application of digital ecosystems concepts to a biological ecosystem simulation problem. The problem involves the use of a digital ecosystem agent to optimize the accuracy of a second digital ecosystem agent, the biological ecosystem simulation. The study also incorporates social ecosystems, with a technological solution design subsystem communicating with a science subsystem and simulation software developer subsystem to determine key characteristics of the biological ecosystem simulation. The findings show similarities between the issues involved in digital ecosystem collaboration and those occurring when digital ecosystems interact with biological ecosystems. The results also suggest that even precise semantic descriptions and comprehensive ontologies may be insufficient to describe agents in enough detail for use within digital ecosystems, and a number of solutions to this problem are proposed.

Digital access to knowledge in the preschool classroom: Reports from Australia

Australian preschool teachers’ use of Web-searching in their classroom practice was examined (N = 131). Availability of Internet-enabled digital technology and the contribution of teacher demographic characteristics, comfort with digital technologies and beliefs about their use were assessed. Internet-enabled technologies were available in 53% (n = 69) of classrooms. Within these classrooms, teacher age and beliefs predicted Web-searching practice. Although comfortable with digital access of knowledge in their everyday life, teachers reported less comfort with Web-searching in the context of their classroom practice. The findings identify the provision of Internet-enabled technologies and professional development as actions to support effective and confident inclusion of Web-searching in classrooms. Such actions are necessary to align with national policy documents that define acquisition of digital literacies as a goal and assert digital access to knowledge as an issue of equity.

Seamless journeys : enhancing accessibility to work through digital technologies for people with mobility-related impairments

Numerous disruptions and barriers are encountered by persons with mobility-related disabilities in their daily’s experience of going to work and the pressure these exert on gaining and maintaining their employment. The nature and extent of their difficulties to workforce participation entails a requirement for extensive planning and also strategies to address problems of being stranded (for example, when the bus they are waiting for is not accessible). This paper presents the conceptualisation and methods of understanding workforce participation as a journey, and a discussion on the role digital technologies play in helping people with mobility-related disabilities in their journeys to work and mitigating disruptions when these occur. This is presented through an initial case study that helped identify the sequence of supports needed to be in place to make the work journey possible. Importantly, the paper also highlights points of intervention for the use of digital technologies and where design can potentially help to enhance accessibility to work for people with mobility-related impairments by making journeys to work seamless.
