( 1999 ): 247 – 260 , https://doi.org/10.1002/(SICI)1097‐0363(19990915)31:1<247::AID‐FLD966>3.0.CO;2‐D . The above article, published online on 14 September 1999 in Wiley Online Library ( wileyonlinelibrary.com ), has been retracted by agreement between the authors; the journal Editor‐in‐Chief, Alina Bruma; and John Wiley & Sons Ltd. The retraction has been agreed due to the authors' discovery that the proper permissions for use of Table 1 and Figures 4, 5, 6, 7, and 8 were not obtained prior to publication. As it was not possible to obtain retrospective permission, the article must therefore be retracted.
