OBJECTIVE Confirmatory randomised controlled trials require solid justifications, especially with regard to whether the experimental intervention is promising. Such evidence is generated in exploratory trials. However, empirical evidence shows that the quality of such trials is still suboptimal. More generally, the development process of healthcare interventions and especially of drugs, remains...

The question of whether environmental heat energy could be utilized as a source ofenergy for biological metabolism is the center this exploratory research. In 1979, thisauthor postulated hypothesis existence thermotrophs that isothermallyutilize their on Earth. Accordingto hypothesis, first primitive forms life in theearly Earth environment. chemotrophs and phototrophs we currently are allwell ...

In this paper, we present a coordination model for exploratory multi-view visualization. We base our work on current research in exploratory visualization and other disciplines. Our model is based on sharing abstract objects such as the visualization parameters of the dataflow model to achieve coordinated exploratory tasks in multiple views. This model describes how current coordinations in exp...

Philosophers of experiment have acknowledged that experiments are often more than mere hypothesis-tests, once thought to be an experiment’s exclusive calling. Drawing on examples from contemporary biology, I make an additional amendment to our understanding of experiment by examining the way that ‘wide’ instrumentation can, for reasons of efficiency, lead scientists away from traditional hypoth...

In our department we have a long history of developing interfaces for learning, which are framed by constructivist and constructionist theories of learning. Thus we try to create effective opportunities for communication, exploratory and collaborative learning and working in common learning spaces. We build this specialization upon software platforms like SuperLogo and Imagine Logo (software en...

Electronic aggression, or cyberbullying, is a relatively new phenomenon. As such, consistency in how the construct is defined and operationalized has not yet been achieved, inhibiting a thorough understanding of the construct and how it relates to developmental outcomes. In a series of two studies, exploratory and confirmatory factor analyses (EFAs and CFAs respectively) were used to examine wh...
