Spanish or Portuguese and French abstracts will be edited by our editorial consultants. Examples can be found in recent volumes of the Journal. Please list as well five key words that characterize the content of your manuscript for indexing purposes. Headings are written in capital letters. If third-order headings are necessary, they are written in capital and lower case letters, indented as in a normal paragraph, and followed by a period.
Text immediately follows a third-order heading.
Do not use more than three orders of headings. This style is permitted occasionally for variety. Generally, titles of published works do not appear in the text. Follow examples below to cite previously published articles, books, and materials. Note that commas separate multiple works by a single author, semicolons separate works by different authors.
