The
work described in your article must have been carried out in accordance with
The Code of Ethics of the World Medical Association
(Declaration of Helsinki) for experiments involving humans
http://www.wma.net/e/policy/b3.htm;
EC Directive 86/609/EEC
for animal experiments
http://ec.europa.eu/environment/chemicals/lab_animals/legislation_en.htm;
Uniform Requirements
for manuscripts submitted to Biomedical journals
http://www.icmje.org. This must be stated at an appropriate point
in the article.
Conflict of interest
All authors are requested to disclose
any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations
within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. See
also
http://www.elsevier.com/conflictsofinterest.
Submission declaration
Submission of an article implies that the work described has not been published previously (except in the form of an abstract
or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication
is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted,
it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the copyright-holder.
Contributors
Each author is required to declare his or her individual contribution to the article: all authors
must have materially participated in the research and/or article preparation, so roles for all authors should be described. The statement
that all authors have approved the final article should be true and included in the disclosure.
Copyright
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more
information on this and copyright see
http://www.elsevier.com/copyright). Acceptance of the agreement will ensure the widest
possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together
with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.
Subscribers may reproduce tables of
contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of the Publisher
is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations
(please consult
http://www.elsevier.com/permissions). If excerpts from other copyrighted works are included, the author(s)
must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted forms for use
by authors in these cases: please consult
http://www.elsevier.com/permissions.
Retained author rights
As an author you (or your employer or institution) retain certain rights; for details you are referred
to:
http://www.elsevier.com/authorsrights.
Role of the funding source
You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article
and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data;
in the writing of the report; and in the decision to submit the paper for publication. If the funding source(s) had no such involvement
then this should be stated. Please see
http://www.elsevier.com/funding.
Funding body agreements and policies
Elsevier has established agreements and developed policies to allow authors whose
articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions
of their grant awards. To learn more about existing agreements and policies please visit
http://www.elsevier.com/fundingbodies.
Language and language services
Please write your text in good English (American or British usage is accepted,
but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission
please visit
http://www.elsevier.com/languagepolishing or our customer support site at
http://epsupport.elsevier.com
for more information. Please note Elsevier neither endorses nor takes responsibility for any products, goods or services offered by outside
vendors through our services or in any advertising. For more information please refer to our Terms & Conditions:
http://www.elsevier.com/termsandconditions.
Submission
Submission to this journal proceeds totally online and you will be guided stepwise through
the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is
used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the
review process, these source files are needed for further processing after acceptance. All correspondence, including notification of
the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.
Accordingly, users need to keep their contact coordinates on the registration page up-todate, using the "UPDATE
MY INFORMATION" option.

>P>There is no submission fee or paper charges.
Use of wordprocessing software
It is important that the file be saved in the native format of the wordprocessor
used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed
and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words.
However, do use bold face, italics, subscripts, superscripts etc. Do not embed "graphically designed" equations or tables, but prepare
these using the wordprocessor's facility. When preparing tables, if you are using a table grid, use only one grid for each individual
table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared
in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier:
http://www.elsevier.com/guidepublication).
Do not import the figures into the text file but, instead, indicate their approximate locations directly in the electronic text and on
the manuscript. See also the section on Electronic illustrations.
To avoid unnecessary errors you are strongly advised to use the
"spell-check" and "grammar-check" functions of your wordprocessor.
LaTeX
If
the LaTeX file is suitable, proofs will be produced without rekeying the text. The article should preferably be written using Elsevier's
document class "elsarticle", or alternatively the standard document class "article".
The Elsevier LaTeX style file package (including
detailed instructions for LaTeX preparation) can be obtained from the Quickguide:
http://www.elsevier.com/latex. It consists
of the file: elsarticle.cls, complete user documentation for the class file, bibliographic style files in various styles, and template
files for a quick start.
Article structure
Subdivision - numbered sections
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.
Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which
may stand alone or form a subsection of a Discussion or Results and Discussion section.
Appendices
If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in
appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on.
Essential title page information
•
Title.
Concise and informative. Titles are often
used in information-retrieval systems. Avoid abbreviations and formulae where possible.
•
Author names and affiliations.
Where the family name may be ambiguous (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 lower-case 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 will 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.
•
Present/permanent
address.
If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address"
(or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work
must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
Abstract
A concise and factual abstract is required. The abstract should state briefly the purpose of the
research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able
to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard
or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Keywords
Immediately after the abstract, provide a maximum of 6 keywords, using either British or American
spelling, but be consistent, and 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.
Acknowledgements
Collate acknowledgements in a separate section at the end of the article before the references
and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided
help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Math formulae
Present simple formulae in the line of normal text where possible and use the solidus (/)
instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of
e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if
referred to explicitly in the text).
Footnotes
Footnotes should be used
sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into
the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes
themselves separately at the end of the article. Do not include footnotes in the Reference list.
Table footnotes
Indicate
each footnote in a table with a superscript lowercase letter.
Artwork
Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office
files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure,
at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether
or not these illustrations are reproduced in color in the printed version.
For color reproduction in print, you will receive information
regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color in print or on
the Web only. For further information on the preparation of electronic artwork, please see
http://www.elsevier.com/artworkinstructions.
Please note: Because of technical complications which can arise by converting color figures to "gray scale" (for the printed version
should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.
Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached
to the figure. A caption should comprise a brief title (
not on the figure itself) and a description of the illustration. Keep
text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Tables
Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the
table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that
the data presented in tables do not duplicate results described elsewhere in the article.
References
Citation in text
Please ensure that every reference
cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full.
Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these
references are included in the reference list they should follow the standard reference style of the journal and should include a substitution
of the publication date with either "Unpublished results" or "Personal communication" Citation of a reference as "in press" implies that
the item has been accepted for publication.
Web references
As a minimum,
the full URL should be given. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.),
should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired,
or can be included in the reference list.
References in a special issue
Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles
in the same Special Issue.
Reference style
Text: Indicate
references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s)
must always be given.
Example: "..... as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ...."
List:
Number the references (numbers in square brackets) in the list in the order in which they appear in the text.
Examples:
Reference to a journal publication:
[1] J. van der Geer, J.A.J. Hanraads, R.A. Lupton, The art of writing a scientific article,
J. Sci. Commun. 163 (2000) 51-59.
Reference to a book:
[2] W. Strunk Jr., E.B. White, The Elements of Style, third ed., Macmillan,
New York, 1979.
Reference to a chapter in an edited book:
[3] G.R. Mettam, L.B. Adams, How to prepare an electronic version of
your article, in: B.S. Jones, R.Z. Smith (Eds.), Introduction to the Electronic Age, E-Publishing Inc., New York, 1999, pp. 281-304.
Reference Style
Text: All citations in the text should refer to:
1.
Single author:
the author's name (without initials, unless there is ambiguity) and the year of publication;
2.
Two authors: both authors'
names and the year of publication;
3.
Three or more authors: first author's name followed by 'et al.' and the year of publication.
Citations may be made directly (or parenthetically).
Groups of references should be listed first alphabetically, then chronologically.
Examples: "as demonstrated (Allan, 1996a, 1996b, 1999; Allan and Jones, 1995). Kramer et al. (2000) have recently shown ...."
List:
References should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from
the same author(s) in the same year must be identified by the letters "a", "b", "c", etc., placed after the year of publication.
Journal titles should be spelled out in full. Personal communications should be cited as such in the text and should not be included
in the reference list. Please note the following examples:
Reference to a journal article:
Anselin, L., Varga, A.,
Acs, Z., 1997. Local geographic spillovers between university and high technology innovations, Journal of Urban Economics 42, 442-448.
Reference to a book:

Citing and listing
of Web references. As a minimum, the full URL should be given. Any further information, if known (Author names, dates, reference to a
source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different
heading if desired, or can be included in the reference list.
References in articles in Special Issues:
Please ensure that
the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special
Issue.
Supplementary material
Elsevier accepts electronic supplementary
material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting
applications, movies, animation sequences, high-resolution images, background datasets, sound clips and more. Supplementary files supplied
will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com.
In order to ensure that your submitted material is directly usable, please ensure that data are provided in one of our recommended file
formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption
for each file. Video files: please supply 'stills' with your files: you can choose any frame from the video or make a separate image.
These will be used instead of standard icons and will personalize the link to your supplementary information. For more detailed instructions
please visit our artwork instruction pages at
http://www.elsevier.com/artworkinstructions.

Use of the Digital Object Identifier
The Digital Object Identifier (DOI)
may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to
a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium
for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The
correct format for citing a DOI is shown as follows (example taken from a document in the journal
Physics Letters B):
doi:10.1016/j.physletb.2003.10.071
When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed never to change.
Proofs
One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do
not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download
the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe
Reader version 7 (or higher) available free from
http://www.adobe.com/products/acrobat/readstep2.html. Instructions on how
to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site:
http://www.adobe.com/products/acrobat/acrrsystemreqs.html#70win.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and
return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then
mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan
the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the
text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission
from the Editor. We will do everything possible to get your article published quickly and accurately. Therefore, it is important to ensure
that all of your corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent
corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of
your article if no response is received.
Offprints
The corresponding author,
at no cost, will be provided with a PDF file of the article via e-mail. The PDF file is a watermarked version of the published article
and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use. Additional paper
offprints can be ordered by the authors. An order form with prices will be sent to the corresponding author.
For inquiries relating to the submission of articles (including electronic submission
where available) please visit this journal's homepage. You can track accepted articles at
http://www.elsevier.com/trackarticle
and set up e-mail alerts to inform you of when an article's status has changed. Also accessible from here is information on copyright,
frequently asked questions and more. Contact details for questions arising after acceptance of an article, especially those relating
to proofs, will be provided by the publisher.
