This paper proposes a research methodology, Lab-based Action Design Research, which combines organizational intervention (action research), building innovative artifacts (engineering research) and studies of software development practice (behavioral research) within a laboratory environment. Seven principles for successful Lab-based Action Design Research are proposed – attract funding with a w...

The main goal of microarray experiments is to select a small subset of genes that are differentially expressed among competing mRNA samples. For a given set of such mRNA samples, it is possible to consider a number of two-color cDNA microarray designs with a fixed number of arrays. Appropriate criteria can be used to select an efficient design from such a set of alternative experimental designs...

A primary advantage of functional magnetic resonance imaging (fMRI) over other techniques in neuroscience is its flexibility. Researchers have used fMRI to study a remarkable diversity of topics, from basic processes of perception and memory, to the complex mechanisms of economic decision making and moral cognition. The chief contributor to this experimental flexibility-indeed, to the growth of...
