Learners may develop expertise by experiencing numerous different but relevant situations. Computer games and virtual simulations can facilitate these training opportunities, however, because of the relative difficulty in authoring new scenarios, the increasing need for new and different scenarios becomes a bottleneck in the learning process. Furthermore, a one-size-fits-all scenario may not ad...

In this article, the authors report the results of a case study examining a group-based exercise program for older adult men. The purpose of the investigation was to identify the elements of this program responsible for its appeal. Interviews, conducted with a purposely sampled subset of program members, were subject to content-analytic procedures. Participants identified social connectedness (...

The microbiome of the human body represents a symbiosis of microbial networks spanning multiple organ systems. Bacteria predominantly represent the diversity of human microbiota, but not to be forgotten are fungi, viruses, and protists. Mounting evidence points to the fact that the "microbial signature" is host-specific and relatively stable over time. As our understanding of the human microbio...

Thanks to technology-pervaded learning environments, digital natives can experiment new engaging ways of learning together at school. In particular, large displays with multi-touch technology hold new opportunities for the learning process, through the dialogic interaction between students and the simultaneous physical interaction with the screen. Our research suggests the use of a context-awar...

This study draws on data from focus groups involving 50 young people from low-income families in Hong Kong to investigate their school-to-work experiences. In line with the ecological-developmental perspective, our results show that contextual influences, including lower levels of parental involvement and lack of opportunities for further education or skill development, constrain both the formu...

Trends across nations suggest that adulthood in the future will require greater social versatility, including abilities to function in relationships that are less scripted by community norms and that bridge multiple social worlds. This article assesses whether current changes in adolescents’ interpersonal experience are likely to give them the social resources and competencies they will need. C...

What are the strengths, gaps, expectations, and barriers to research engagement in clinical trials as communicated through social media? Clinical trials test treatments to provide reliable information for safety and effectiveness. Trials are building blocks in which what is learned in earlier research can be used to improve treatments, compare alternatives, and improve quality of life. For 20 y...

Many transition and developing economies have reduced direct public involvement in the production and trade of seed and other agricultural inputs. This trend creates opportunities for farmers to realize improved access to inputs, including technology from international private research. Unfortunately, input regulations often derail these opportunities by blocking private entry and the introduct...

Abstract This fundamentals article discusses efficient machine economies in which non-human agents can autonomously exchange information and value. We first identify criteria for achieving Pareto efficiency such by drawing on the Coase Theorem. then translate these economic to technical requirements before developing a framework that characterizes four types of economies. discuss real-life exam...

It has been widely argued that effective citizenship education should focus on more than mere teaching of civic knowledge, but provide a wider range opportunities for the experience participation and development skills, efficacy interest instrumental to active citizenship. Opportunities critical reflection such as open classroom discussions, fairness at school, institutional student school acti...
