ACKNOWLEDGMENTS
The authors would like to thank all of the 2001 WISE participants and, in particular, those that submitted articles for consideration in the special issues. The special issues would not have been possible without the understanding of the reviewers and their invaluable feedback to the editors and authors. Finally, we would like to thank John Knight, Steve McConnell, and Warren Harrison for their encouragement of the linked special issues idea, and the editorial staff of both Software and TSE for their support.
