Because abstracts are circulated by abstracting agencies, it is important that they represent the research clearly and concisely. Text must be typed double-spaced throughout. Text footnotes should be numbered with Arabic numerals and typed on a separate sheet of paper. Footnote all personal communications, unpublished data, and unpublished manuscripts with full address of the communicator or author, or, as in the case of unpublished data, where the data are on file. Follow the name and year system for citation format.
Authors are responsible for the accuracy and completeness of all citations.
Tables should not be excessive in size and must be cited in numerical order in the text. Headings should be short but ample enough to allow the table to be intelligible on its own. All unusual symbols must be explained in the table heading. Other incidental comments may be footnoted with italic numerals. Use asterisks for probability in statistical data.
