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
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carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any
other language, without the written consent of the copyright-holder.
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.
Open access
This journal offers you the option of making your article freely available to all via the ScienceDirect
platform. To prevent any conflict of interest, you can only make this choice after receiving notification that your article has been
accepted for publication. The fee of $3,000 excludes taxes and other potential author fees such as color charges. In some cases, institutions
and funding bodies have entered into agreement with Elsevier to meet these fees on behalf of their authors. Details of these agreements
are available at
http://www.elsevier.com/fundingbodies. Authors of accepted articles, who wish to take advantage of this
option, should complete and submit the order form (available at
http://www.elsevier.com/locate/openaccessform.pdf). Whatever
access option you choose, you retain many rights as an author, including the right to post a revised personal version of your article
on your own website. More information can be found here:
http://www.elsevier.com/authorsrights.
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.
Peer review policy
In order to maintain a rapid rate
of review all submitted manuscripts are initially reviewed by the Editor in Chief for completeness and appropriateness to the journal's
stated Aims and Scope. Manuscripts that pass the initial review will be handled by the Editor, sent out to reviewers in the field, sent
to an associate editor for handling, or some combination thereof, solely at the discretion of the Editor.
If for any reason you have
questions about the peer review policy in general or with regards to your paper specifically, please address them directly to the Editor
in Chief, Johnny Matson:
johnmatson@aol.com.
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.
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.
Material and methods
Provide
sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications
should be described.
Theory/calculation
A Theory section should extend,
not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast,
a Calculation section represents a practical development from a theoretical basis.
Results
Results should be clear and concise.
Discussion
This should explore
the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive
citations and discussion of published literature.
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. Similarly for tables and figures: Table A.1; Fig. A.1, etc.
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 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.
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 mandatory for this journal.
They consist of a short collection of bullet points that convey the core findings of the article 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
Abbreviations should be held to a minimum and should appear only after the full length term has
been spelled out once in the text.
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
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
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 and the date when the reference was last
accessed. 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 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: Citations
in the text should follow the referencing style used by the American Psychological Association. You are referred to the Publication Manual
of the American Psychological Association, Sixth Edition, ISBN 978-1-4338-0561-5, copies of which may be ordered from

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.

Additional information
The word
retarded should be used as an adjective rather than a noun;
retardate should be avoided. Terms that are scientifically
precise should be adhered to. Therefore,
mentally retarded will be preferred to retarded because it specifies the type of retardation,
and
intellectually average or
normal intelligence will be preferred over
normal. A similar format should be
followed if other disabilities are involved. It is understood that all investigations have been approved by the human subjects review
committee of the author's institution.
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.
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
