Logical organization is essential.
While headings help to structure the content, titles and headings within the manuscript should be as short as possible. Do not use the general masculine pronoun or other sexist terminology. In addition, whenever possible a computer diskette should be included, clearly marked with the name of the file containing the manuscript and the hardware and software used. There are no absolute limits on length of articles, but authors should strive for conciseness. Include a name and postal address for reprint requests.
