Ethics in publishing
For information on Ethics in publishing and Ethical guidelines for journal publication
see
http://www.elsevier.com/publishingethics and
http://www.elsevier.com/ethicalguidelines.
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 and verification
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the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language,
including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the
originality detection software iThenticate. See also
http://www.elsevier.com/editors/plagdetect.
Changes
to authorship
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted
manuscripts:
Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange
the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a)
the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from
all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes
confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the
Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform
the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship
has been agreed.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange
author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.
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 article 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://webshop.elsevier.com/languageservices or our customer support site at
http://support.elsevier.com for more information.
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.
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. 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).
Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also
the section on Electronic artwork.
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 any
of the other recognized classes and formats supported in Elsevier's electronic submissions system, for further information see
http://www.elsevier.com/wps/find/authorsview.authors/latex-ees-supported.
The Elsevier 'elsarticle' 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.
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. Contact details must be kept up to date by the corresponding author.
•
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
self-contained abstract (50-100 words) outlining in a single paragraph the aims, scope and conclusions of the paper must be supplied.
Graphical abstract
A Graphical abstract is optional and should summarize the contents of the article in a
concise, pictorial form designed to capture the attention of a wide readership online. Authors must provide images that clearly represent
the work described in the article. Graphical abstracts should be submitted as a separate file in the online submission system. Image
size: Please provide an image with a minimum of 531 × 1328 pixels (h × w) or proportionally more. The image should be readable
at a size of 5 × 13 cm using a regular screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. See
http://www.elsevier.com/graphicalabstracts for examples.
Authors can make use of Elsevier's Illustration and Enhancement
service to ensure the best presentation of their images also in accordance with all technical requirements:
Illustration Service.
Highlights
Highlights are a short collection
of bullet points that convey the core findings of the article. Highlights are optional and should be submitted in a separate file in
the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including
spaces, per bullet point). See
http://www.elsevier.com/highlights for examples.
Keywords
Immediately
after the abstract, provide 5-10 keywords.
Nomenclature and units
The SI system should be
used for all scientific and laboratory data; if, in certain instances, it is necessary to quote other units, these should be added in
parentheses. Temperatures should be given in degrees Celsius. The unit 'billion' (109 in America, 1012 in Europe) is ambiguous and must
not be used.
Artwork
Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your original artwork.
• Save text in illustrations as 'graphics'
or enclose the font.
• Only use the following fonts in your illustrations: Arial, Courier, Times, Symbol.
• Number
the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
•
Provide captions to illustrations separately.
• Produce images near to the desired size of the printed version.
• Submit
each figure as a separate file.
A detailed guide on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions
You are urged to visit this site; some excerpts from the detailed information are given here.
Formats
Regardless
of the application used, when your electronic artwork is finalised, please 'save as' or convert the images to one of the following formats
(note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings.
Embed the font or save the text as 'graphics'.
TIFF: Color or grayscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or grayscale): a
minimum of 500 dpi is required.
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel)
then please supply 'as is'.
Please do not:
• Supply files that are optimised for screen use (e.g., GIF, BMP, PICT,
WPG); the resolution is too low;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately
large for the content.
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
Present tables and figure
legends on separate pages at the end of the manuscript.
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
Reference management software
This
journal has standard templates available in key reference management packages EndNote (
http://www.endnote.com/support/enstyles.asp)
and Reference Manager (
http://refman.com/support/rmstyles.asp). Using plug-ins to wordprocessing packages, authors only
need to select the appropriate journal template when preparing their article and the list of references and citations to these will be
formatted according to the journal style which is described below.
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, 2000a, 2000b, 1999;
Allan and Jones, 1999). Kramer et al. (2010) 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.
Examples:
Reference to a journal publication:
Van der Geer, J., Hanraads, J.A.J., Lupton, R.A., 2010. The art of writing a scientific article. J. Sci. Commun. 163, 51–59.

Video
data
Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who
have video or animation files that they wish to submit with their article are strongly encouraged to include these within the body of
the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body
text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content.
In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file
formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in the electronic version
of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com. Please supply 'stills'
with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard
icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at
http://www.elsevier.com/artworkinstructions.
Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and
the print version for the portions of the article that refer to this content.
Supplementary data
Elsevier
accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional
possibilities to publish supporting applications, 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 provide the data
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. 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.2010.09.059
When you use the DOI to create URL
hyperlinks to documents on the web, the DOIs 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://get.adobe.com/reader. 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/reader/tech-specs.html.
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 – please let us have all your corrections within
48 hours. It is important to ensure that all 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. For an extra charge, paper offprints can be ordered via
the offprint order form which is sent once the article is accepted for publication. 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.
For inquiries relating to the submission of articles (including electronic submission) please
visit this journal's homepage. Contact details for questions arising after acceptance of an article, especially those relating to proofs,
will be provided by the publisher. You can track accepted articles at
http://www.elsevier.com/trackarticle. You can also
check our Author FAQs (
http://www.elsevier.com/authorFAQ) and/or contact Customer Support via
http://support.elsevier.com.
