Please, check carefully that the electronic file corresponds to the hard copy of the paper. Extra formatting of the text, such as underlining, borders and frames, small capitals, etc. should be avoided. Also, footnotes should be placed at the end of the paper and not inserted into the text. For references, please follow the instructions for authors.
Tables are often retyped, therefore a hard copy is also necessary.
Figures Electronic figures are welcome. These should be placed in different files than the text file. They should be saved in EPS, TIFF, JPEG formats using standard fonts and high resolution. In case scanning is necessary, please provide good-quality originals for your figures. Parts of diagrams, graphs, should be clearly indicated by different types of hatching.
