Figures may only be supplied in black and white. Authors are required to ensure where possible that figures reproduce clearly in grey-scale. Figures should be submitted in electronic format, preferably in MS Word, Excel or PowerPoint. More detailed graphics should be submitted as EPS files with fonts embedded or as TIFF files.
Figures should be referred to in the text and numbered consecutively. They should be supplied separately from the main body of the text, with their approximate final positions, and legends marked within the main text.
Figure legends should describe the figure content and should be understood independently from the text.
Most figures will be set portrait-style (145 mm), or if necessary landscape (210 mm). Figures should be prepared to publication size with all labeling in Times New Roman, no smaller than 10 point. Where possible, a reasonably sized key should be included, ideally in the right-hand corner.
Abbreviations should be avoided in figures. If abbreviations or symbols are used in the figures they should be explained in the figure legend, if they have not been explained in the key.
Line charts, bar charts and pie charts should be two-dimensional, with single categories, a generous margin, and no shading in the background. Appropriate scales should be used and sources should be quoted.
Bar charts should have two categories or more and at least five observations; otherwise the data should be presented in a table. Horizontal lines should be used to mark the major values on the y-axis.
Line charts should show changes over long time spans and should have at least ten observations.
Pie charts should be used to show proportions and have a minimum of four segments, and a maximum of twelve.
Tables should be submitted in electronic form, preferably in MS Word or Excel.
Tables should be referred to in the text and numbered consecutively. They should be supplied separately from the main body of the text, with their approximate final positions indicated in the text.
Each column should have a short heading and, where appropriate, the units should be stated.
Table legends should describe the content and should be understood independently from the text.
Data columns should be right-hand aligned, or aligned by decimal place, where appropriate; data should be sorted where possible.
Footnotes should be included on the same pages as the tables themselves and should be used to explain any abbreviations used in the table and denote them by letter. Footnotes should also be used to quote sources.
