AUTHOR INQUIRIES



The African Journal of Emergency Medicine (AfJEM, ISSN: 2211-419X) is the official journal of the African Federation for Emergency Medicine. It is an international, peer-reviewed journal aimed in particular at supporting emergency care across Africa. AfJEM publishes original research, reviews, brief reports of scientific investigations, case reports as well as commentary and correspondence related to topics of scientific, ethical, social and economic importance to emergency care in Africa. Articles will be of direct importance to African emergency care, but may have originated from elsewhere in the world.

TYPES OF ARTICLES

Authorship

All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

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.

Clinical trial results

In line with the position of the International Committee of Medical Journal Editors, the journal will not consider results posted in the same clinical trials registry in which primary registration resides to be prior publication if the results posted are presented in the form of a brief structured (less than 500 words) abstract or table. However, divulging results in other circumstances (e.g., investors' meetings) is discouraged and may jeopardise consideration of the manuscript. Authors should fully disclose all posting in registries of results of the same or closely related work.

Open access (OA)

There is no publication fee for this journal. On publication, articles are made freely available to all (including non-subscribers) via the ScienceDirect platform. Learn more about Elsevier's pricing policy: http://www.elsevier.com/openaccesspricing

Language and language services

Please write your text in UK English by setting your word processor to English (U.K.). Authors who require information about language editing and copyediting services pre- and post-submission please visit http://webshop.elsevier.com/languageediting or our customer support site at http://support.elsevier.com for more information. Also see Author Assist below.

Author Assist It is the aim of the AfJEM to be representative of all parts of the African continent; we recognise within this that some African researchers in emergency care may be disadvantaged in the available range of journals into which they can publish their work. We are aware that this is due to many reasons, including that topics are concerned with www.afjem.com conditions which are largely irrelevant to other audiences. AfJEM is dedicated to supporting all authors who wish to publish on an African emergency care topic. In order to maintain and produce a high quality, international standard Emergency Medicine journal, AfJEM has devised Author Assist. AfJEM enlists the help of a team of experienced volunteers (Author Assistants) to help improve the quality of manuscripts before peer-review submission. Go to http://www.afjem.com/author-assistance.html for more information.

Submission

Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.

Submit your article
Please submit your article via http://ees.elsevier.com/afjem.

Peer review and Referees

Each paper submitted to the journal is firstly checked for completeness and similarity by the technical editor followed by an initial desk review by one of the editors-in-chief. Papers not suitable for publication are either rejected outright (out-of-scope) or rejected- refer Author Assist (within scope, but poor quality). This is usually done within the first three to five days. Papers accepted for peer review are then assigned to an associate editor who takes responsibility for assigning peer reviewers and providing a synthesis of reviews to the editor-in-chief for a decision. All original content submitted to the AfJEM is peer reviewed by a minimum of two and up to four reviewers. Editorials, op-ed pieces and regular features are reviewed by a single expert reviewer, usually an associate editor of the journal. Peer review is double blinded (authors and reviewers never learn each other’s identities). The latter is specifically required to compliment the Author Assist process. AfJEM operates a strict peer reviewer code of conduct policy. Details can be found in the Reviewer Area on http://www.afjem.com. Authors are encouraged to submit the names and institutional e-mail addresses of several potential referees. For more details, visit our Support site. Note that an editor retains the sole right to decide whether or not the suggested reviewers are used.

Use of word processing software

It is important that the file be saved in the native format of the word processor 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 word processor'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 word processor.

Article Structure

Ensure that author identifiers are not included in the main manuscript file submitted. Inclusion of an abstract in the manuscript is not required. Consult the guidance and checklists described in Types of Articles above to structure your manuscript correctly. Original articles, brief research reports and systematic reviews require the checklist to be submitted as a supplementary file. Where this has not been supplied, the manuscript will be returned to the author.

Subdivision
Divide your article into clearly defined sections as per the guidance given in Types of Articles above. Numbers are not to be used for sections or subsections. Section headings should be in bold. Subsection headings should be in italics. Each heading should appear on its own separate line. Subsections in addition to the sections described in Types of Articles above should be used sparingly.

Clinical trial results
In line with the position of the International Committee of Medical Journal Editors, the journal will not consider results posted in the same clinical trials registry in which primary registration resides to be prior publication if the results posted are presented in the form of a brief structured (less than 500 words) abstract or table. However, divulging results in other circumstances (e.g., investors' meetings) is discouraged and may jeopardise consideration of the manuscript. Authors should fully disclose all posting in registries of results of the same or closely related work.

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, it should be identified starting with Appendix B, C, etc. Do not use Appendix A. Formulae and equations in appendices should be given separate numbering: Eq. (B.1), Eq. (B.2), etc.; in a subsequent appendix, Eq. (C.1) and so on. Similarly for tables and figures: Table B.1; Fig. B.1, etc. All appendices will be considered online material only.

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 phone 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.
Word count. Please provide a word count
Table/figure count. Please provide a table/ figure count

Abstract

A concise and factual abstract of no more than 300 words 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. Non-standard or uncommon abbreviations should be avoided, but if essential, it must be defined at the first mention. With the exception of a submission for Editorials, Practical pearl, Correspondence and Erratum, structured abstracts are required for all article types

Types of abstracts include:

  • Research abstracts should adhere to the following format: Introduction, Methods, Results and Conclusion.
  • Case reports should adhere to the following format: Introduction, Case report and Discussion.
  • Narrative abstracts are acceptable for non-research abstracts (concepts and commentary)

Keywords

The submission system will prompt authors to provide a maximum of 6 keywords, using American spelling 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.

Abbreviations

Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.

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.).

Statistics

Describe statistical methods with enough detail to enable a knowledgeable reader with access to the original data to verify the reported results. References for the design of the study and complex or unusual statistical methods should be to standard works when possible (with pages stated). Commonly used methods such as the chi-square test, t-test, ANOVA, linear and logistic regression need not be referenced. Define statistical terms, www.afjem.com abbreviations, and most symbols. Technical statistical terms should ideally be replaced by simpler terms where possible and referenced if not. Specify the computer software used. The results section must be written so the average reader can understand the findings. The methods section is allowed to be more complex if unavoidable. When possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). For normally distributed data give means and confidence intervals and for data that is not normally distributed give the median and interquartile range. Avoid relying solely on statistical hypothesis testing, such as p-values. If p-values are used, include 2 digits of precision (i.e. p=0.65) for values greater than 0.01. Give 3 digits for values between 0.01 and 0.001 and report values smaller than 0.001 as p < 0.001. Describing non-significant p-values as NS is not acceptable and a numerical value should be given. When using tables consider including counts and percentages. In general, including the chi-square statistic, t statistic, F statistic and degrees of freedom is not useful. Regression output should be limited to the most important findings. Estimates of variance explained (R2, correlation coefficients, and standardised regression coefficients or effect size) should not be presented as the main result of the analysis.

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). Bear in mind that complex formulae, such as log likelihood expressions or symbolic expressions for regression models are often beyond the grasp of the average reader. Consider making this available as an online only appendix.

Footnotes

Footnotes are discouraged and when used should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many word processors 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.

Mandatory statements

Mandatory statements are included in the word count and should be placed just before the reference section.

1. Conflict of interest
If no conflict of interest exists please state: The author(s) declare no conflict of interest Conflicts of interests that require disclosure include, but are not limited to:

  • a. Associations with commercial entities that provided support for the work reported in the submitted manuscript (the timeframe for disclosure in this section of the form is the life span of the work being reported).
  • b. Associations with commercial entities that could be viewed as having an interest in the general area of the submitted manuscript (in the three years before submission of the manuscript).
  • c. Non-financial associations that may be relevant or seen as relevant to the submitted manuscript.

Example: I the author (/We, the authors), declare the following interests: AA has received speaker fees from BBB company. CC has received fees as an advisory board member for DDD company. EE’s institution receives funding from FFF company for a trial in which he is co-investigator

2. Dissemination of resultsNot required for editorials, review articles, regular features, correspondence or erratum. Provide a brief statement on how findings of this research were disseminated to the community from, or within which it was collected.
Example: Results from this study (research/ trail/ etc.) was shared with staff members at AAA hospital emergency centre through an informal presentation. The results were also published in the hospital’s newsletter.

3. Author contributionPlease provide a brief statement to describe the contributions of authors. Please note that according to the ICMJE an author should fulfil all of the following criteria:

  • a. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work
  • b. Drafting the work or revising it critically for important intellectual content
  • c. Final approval of the version to be published
  • d. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Example: AB and BC conceived the original idea. AB and CD designed the experiments. AB carried out analysis of data. AB, CD and BC prepared the manuscript (note that authors’ names are shortened to initials only)

Artwork

Image manipulation
Whilst it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. For graphical images, this journal is applying the following policy: no specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Adjustments of brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Nonlinear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend.

Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your original artwork.
• Embed the used fonts if the application provides that option.
• Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Size the illustrations close to the desired dimensions of the published version.
• Submit each illustration as a separate file.
A detailed guide on electronic artwork is available on our website:

If, together with your accepted article, you submit usable colour figures then Elsevier will ensure, at no additional charge, that these figures will appear in colour on the Web (e.g., ScienceDirect and other sites) in addition to colour reproduction in print. For further information on the preparation of electronic artwork/ figure, please see http://www.elsevier.com/artworkinstructions.

Artwork Figure captions
Ensure that each illustration/ figure has a caption. Supply captions separately, listed at the end of your manuscript after the references, and not included in the separately uploaded artworks/ figures. 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.

Illustration services

Elsevier's WebShop (http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

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.

Text graphics
Text graphics may be embedded in the text at the appropriate position. See further under Electronic artwork.

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.Tables should be placed within the text where it is referenced. The preferred format for tables is as follow. Include tables in the main text of the manuscript. Each table should be labelled at the top with footnotes at the bottom.

Journal names should be abbreviated according to the List of Title Word Abbreviations: http://www.issn.org/services/online-services/access-to-the-ltwa/. The correct abbreviation for AfJEM is: Afr J Emerg Med

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 links to 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 150 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 material

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.

Additional information
Manuscripts should not exceed 30 typewritten pages for original articles and 6 typewritten pages for short communications (incl. tables and fi gure legends). The editors reserve to themselves the right of condensing any paper submitted.

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. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
http://dx.doi.org/10.1016/j.physletb.2010.09.059
When you use a DOI to create links 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 9 (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. 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.

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). For an extra charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. Both corresponding and co-authors may order offprints at any time via Elsevier's WebShop (http://webshop.elsevier.com/myarticleservices/offprints). Authors requiring printed copies of multiple articles may use Elsevier WebShop's 'Create Your Own Book' service to collate multiple articles within a single cover (http://webshop.elsevier.com/myarticleservices/booklets).
