Abstract

We accept most wordprocessing formats, but Word, Word-Perfect or LaTeX is preferred. An electronic version of the text should be submitted together with the final hardcopy of the manuscript. The electronic version must match the hardcopy exactly. Always keep a backup copy of the electronic file for reference and safety. Label storage media with your name, journal title, and software used. Save your files using the default extension of the program used. No changes to the accepted version are permissible without the explicit approval of the Editor. Electronic files can be stored on 3 1 _ 2 inch diskette, ZIP-disk or CD (either MS-DOS or Macintosh). 2. Preparation of text 2.1. Presentation of manuscript General Please write your text in good English (American or British usage is accepted, but not a mixture of these). Use double spacing and wide (3 cm) margins. (Avoid full justification , i.e., do not use a constant right-hand margin.) Ensure that each new paragraph is clearly indicated. Present tables and figure legends on separate pages at the end of the manuscript. If possible, consult a recent issue of the journal to become familiar with layout and conventions. Number all pages consecutively. Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and for-mulae where possible. Author names and affiliations. Where the family name may be unclear (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lowercase superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author. Corresponding author. Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication , also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Abstract. A concise and factual abstract consisting of one paragraph is required (100-200 words). The abstract should state briefly the scope, the principal results and major conclusions. An abstract is often presented separate from the article, so it must be able to stand alone. The abstract should be informative, not descriptive. It should not serve as an introduction, nor contain references. Keywords. Immediately after the abstract, provide a maximum of 5 keywords, avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes. Abbreviations. Define abbreviations that are not standard in this field at their first occurrence in the article: in the abstract but also in the main text after it. Ensure consistency of abbreviations throughout the article. 2.2. Arrangement of the article Subdivision of the article. Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2,. . .), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text.' Any subsection may be given a brief heading. Each heading should appear on its own separate line. Introduction. State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.
