S ome vertebrates, such as fi sh, amphibians, and lizards, have the ability to replace lost limbs and regenerate organs. Regeneration requires the reactivation of signaling molecules that were used during embryonic development. Weidinger has spent his career so far studying aspects of zebrafish embryogenesis, including the role of Wnt signaling molecules (1, 2), and has more recently been inves...

This paper focuses on argumentative diagrams for computer-supported collaborative argumentation-based learning. Thirty pairs of students discussed two cases on the topic of Genetically Modified Organisms (GMOs) via the computer. They communicated via chat. Pairs of students were either asked to collaboratively construct a diagram using argumentative labels to describe the boxes in the diagram, ...

This paper takes a slightly light-hearted look at what defines an ethical researcher, and concludes that most of research is done in an entirely unethical way. It shows the way forward for such unethical researchers and makes a contribution to the field of ICT research, where questions about ethics have rarely surfaced, let alone been addressed.

This article presents examples of the monumental contributions of Bill McCune to mathematics, logic, computer science, and especially automated reasoning. The examples are presented in the form of short stories and recollections of the author during his long association with Bill. In addition to Bill’s accomplishments as a researcher, the author provides personal memories giving glimpses into B...

We explored the feasibility and usefulness of collecting peer sociometric data on a sample of children from across southeastern New England who were being followed in a community-based longitudinal study. Applying what has typically been a school-focused research methodology to this child-focused follow-up highlighted challenges faced by applied researchers wanting to make use of this powerful ...

National Statistical Institutes [NSIs] are increasingly investigating new ways of providing access to confidential microdata for research purposes. These innovations are being driven by the requirement for NSIs to ensure the best possible return for their investments in data collection coupled with researchers’ increasing demand for highly detailed microdata. After a long period of decline as N...
