Acknowledgments
In lieu of an abstract, here is a brief excerpt of the content:

Acknowledgments his volume results from a project for which Herman Diederiks took the initiative shortly before his death. In the course of that project, the contributions were discussed in three successive meetings: in Menaggio, Italy (1997), Amsterdam (1998), and Berlin (1999). The project was funded by the Volkswagenstiftung in Germany and the N.W. Posthumus Institute (with funds obtained from the Netherlands Organization for Scientific Research, NWO). The editors greatly appreciate the support given by these institutions. We are also grateful to Bernd Roeck for organizing the meeting in Menaggio and to Heinz Schilling for organizing the one in Berlin. vii T Spierenburg_Vol_1_FM_3rd.qxd 6/22/2004 2:36 PM Page vii Spierenburg_Vol_1_FM_3rd.qxd 6/22/2004 2:36 PM Page viii ...
