Guidelines for Submission

SUBMISSION
Manuscripts must be submitted electronically in PDF format, using the Editorial Express Interface.  Correspondence should be sent to the editors.  Contact information can be found above.

COVER LETTER
Along with the manuscript, please upload a cover letter to the editors that indicates that the material has not been offered for publication or published in a similar form elsewhere and, so far as the author(s) knows, does not infringe upon other published material protected by copyright.

TITLE PAGE AND ABSTRACT
Do not include author-identifying information in the manuscript.  However, the Editorial Express interface will ask for author contact information and an abstract.  The abstract should not exceed 100 words.

TEXT PREPARATION
The manuscript should be preapred on 8 1/2" X 11" standard size paper, and all material, including references and footnotes, should be double-spaced with margins of at least 1  inch.  Use 12 point Times or a similar font style and size.

STYLE
Follow the Chicago Manual of Style, 14th ed., University of Chicago Press.

TABLES
Each table should be on a separate page with all material double-spaced. Titles should be short and descriptive.

FIGURES
After a manuscript is accepted, send hard copy originals of figures ready for photographic reproduction. Each figure should be placed on a separate page, and each must have a title. Text within the figures should be in Times or a similar font.

MATHEMATICAL NOTATION
Use only essential mathematical notation. Avoid using the same character for both superscripts and subscripts, using capital letters as superscripts and subscripts, and using overbars, tildes, carets, and other modifications of standard type. Use your word processor's character formatting for bold (vector and matrices), italic (variables), superscript, and subscript styles and use Symbol font whenever possible for typesetting mathematical notation.

FOOTNOTES
In general, the use of footnotes should be avoided. Number all notes consecutively and type double-spaced on separate pages at the end of the manuscript.

REFERENCES
List references alphabetically and unnumbered on a separate page or pages at the end of the manuscript with the heading "References." List only those actually cited. Cite references in the text by the name(s) of the author(s) and the year of the publication. If there is more than one source in a given year, then use, for example, 1981a, 1981b. A style sheet on references and citations is available from the editor.

PAGE CHARGE
A page charge is billed to the department or agency after the article is accepted for publication.
