Proofs Authors will be sent page proofs. Essential changes of an extensive nature may be made only by insertion of a Note Added in Proof. Page charges will not be levied. Authors will, however, be charged for extensive changes made in proof and for special items such as color plates. Times Roman is the preferred typeface for printouts of manuscripts.
Copies made by a clearly legible duplication process are preferred.
Please send one original and three copies of your manuscript. Title page, abstract page, references and figure legends should be on separate pages. Tables, figure legends, and furnished art should be grouped together at the end of the manuscript to facilitate processing. Authors should write in clear, concise English. The responsibility for all aspects of the manuscript preparation rests with the authors.
