AUTHOR INQUIRIES




Australian Critical Care is the official journal of the Australian College of Critical Care Nurses and publishes peer-reviewed scholarly papers that report research findings, research-based reviews, discussion papers and commentaries which are of interest to an international readership of critical care practitioners, educators, administrators and researchers. Papers should address issues of interest to critical care clinicians and present the paper in the context of the existing international research relevant to the topic. Selection of papers for publication is based on scientific excellence, distinctive contribution to knowledge (including methodological development) and their importance to contemporary critical care practice. The journal does not accept manuscripts containing animal experimentation.




Australian Critical Care is a member of the Committee on Publication Ethics (http://publicationethics.org) and abides by its Code of Conduct and Best Practice Guidelines for Editors, Ethical Guidelines for Peer Reviewers, and Cooperation between research institutions and journals on research integrity cases: guidance from the Committee on Publication Ethics (COPE). It is expected that all authors will abide by the Principles of Transparency and Best Practice in Scholarly Publishing. Submitted material will be handled in confidence except for the purposes of review and investigate possible misconduct, including but not limited to concurrent submissions to multiple journals, high percentage of text matching and concerns around research validity, conduct and reporting.

CONSIDERATIONS SPECIFIC TO TYPES OF RESEARCH DESIGNS

Australian Critical Care prioritises papers which make a substantive contribution to the literature and extend what is known in a particular area. Submitted papers should be relevant to critical care practice. As Australian Critical Care has a global readership, authors should place their paper within the international context. Details of national practices, policies, law, etc. should be in the paper to provide information for all readers. The journal is widely distributed internationally, and for many readers English is a second language, therefore authors are requested to write in plain English and use terminology which is internationally acceptable. While Australian Critical Care accepts manuscripts from a range of health professionals, it is important to recognise that nurses are the primary readers of this journal.

Types of articles

Australian Critical Care publishes original research, reviews, case studies and discussion papers. In addition, we publish letters, editorials and commentaries on existing content with the journal. Where a case is made, we will also publish study protocols. Authors of any papers that do not comply with the guidelines below should make preliminary enquiry to the Editor-in-Chief before submitting the manuscript.

Word limits - Our experience suggests readers find shorter papers more useful than longer ones. Given this, and competition for space in the Journal, papers of between 2,000 and 3,500 words are preferred. Word limits are exclusive of figures, tables and references. Additional information to enhance the manuscript, such as copies of developed tools or additional data, can be made available as supplementary files.

Editorials - 1,000–1,500 words
Authors who have ideas for editorials which address issues of substantive concern to the discipline, particularly those of a controversial nature or linked directly to forthcoming content in the journal, should contact the Editor-in-Chief ([email protected]).

Research Papers - 2,000-3,500 words
Full papers reporting original research can be a maximum of 3,500 words in length, although shorter papers are preferred. In some instances, qualitative and mixed-methods papers may be up to 5,000 words in length, where appropriate. Research papers should adhere to recognised standards for reporting (see above guidance and Author Checklist).

All research papers reporting the development of scales must include a copy of the full scale so it can be published as supplementary online material; Australian Critical Care does not accept scale development papers which are not accompanied by a copy of the full scale. For papers reporting the testing of existing scales, the reference of the original paper reporting the scale should be cited. When the original scale has not previously been published, and where possible, authors are encouraged to obtain written permission from the copyright owner to reproduce the scale, and ensure that it is credited appropriately. If original developers of the scale want to retain copyright they can mark it as reproduced with their permission. If the scale is in a language other than English, it must be accompanied by an English translation. If the scale is a translation of an existing scale then Australian Critical Care requires the author(s) to submit written permission from the copyright owner of the original scale to publish the translated version. Full credit will be given to the original scale. Established processes for quality of translation should be adhered to, including the use of back translation.

Clinical Trials - 2,000-3,500 words
Randomised controlled trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrolment, randomisation, withdrawal and completion, and a detailed description of the randomisation procedure. The CONSORT checklist and template flow diagram are available online. Click here http://www.consort-statement.org/.


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 the 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. Authors should fully disclose all posting in registries of results of the same or closely related work.

Registration in a public trial registry is a condition for publication of clinical trials in this journal in accordance with International Committee of Medical Journal Editors (ICMJE, http://www.icmje.org) recommendations. Trials must be registered at or before the onset of participant enrolment. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects of health outcomes. Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example drugs, surgical procedures, devices, behavioural treatments, dietary interventions, and process-of-care changes). Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

The Clinical Trials number (e.g. ISRCTN) should be included in the manuscript and when answering the appropriate question in the manuscript submission process. While Australian Critical Care operates a blind peer review process, we acknowledge the importance of transparency in reporting the results of clinical trials. Authors should be aware that there is potential for the peer reviewer to be able to identify the authorship team.

Brief Research Report - 1500-2500 words
Australian Critical Care accepts brief research reports which follow the same rigour, format and guidelines as original research studies but are designed for small-scale research or research in the early stages of development. These may include preliminary studies that use a simple research design or small sample size and that have produced limited pilot data and initial findings that suggest the need for further investigation. Brief research reports are not intended to be used for research that would otherwise qualify for a full original research manuscript or for publishing research that lacks significance or is not rigorous.

Reviews - 3,000-6,000 words
Australian Critical Care accepts quantitative, qualitative, integrative and scoping reviews for publication. Preference is given to reviews which have previously been registered with PROSPERO, the International Prospective Register of Systematic Reviews (https://www.crd.york.ac.uk/prospero/) or other platforms such as the Open Science Framework – Registries (https://www.cos.io/products/osf-registries). Authors are encouraged to clearly report the process by which literature was selected for inclusion in the review. Relevant reporting guidelines should be adhered to.

Case Reports - up to 2,500 words
Case reports are valuable to the journal, and should report on a unique clinical situation which is not already well described in the literature. Due to their nature, patients featured in the reports may be highly identifiable. The journal requires that appropriate consent for publication has been obtained and that the individual(s) being reported on, or their proxy, is aware of the possible consequences of that reporting, including the possibility that the individual(s) could be identified.

Authors are required to attest that a Patient Consent Form from their institutions or licensing board has been signed by the patient or a proxy. Patient Consent Forms must comply at the very least with Elsevier's policy around requirement for consent (See: https://www.elsevier.com/about/policies/patient-consent). For privacy and confidentiality reasons, the Patient Consent Form(s) must not be uploaded with the manuscript.


In some cases, your Institution may require you to obtain organisational approval prior to submitting your manuscript. Please seek clarification from the organisations Research Office, Director of Research or other organisational lead before submission. It is the author(s) responsibility to adhere to institution specific requirements. If, after publication, the Journal is made aware that institutional approval was required but not sought, this may result in the paper being retracted.

Letters- 300-400 words


Letters to the Editor specific to papers published in the Journal are welcome and should focus on work previously published in the journal. Letters are not to be used to report small scale studies. Letters to the Editor should be submitted through the online submission process.

Commentaries - 2000 words + 15 references
Contributions that are of general interest, stimulating and meet the standards of scholarship associated with the Journal may be selected for publication in a commentary section or as a standalone contribution. Contributions should be submitted online in the usual way. It is important that commentaries extend thinking and add to the discussion on a particular topic.

Study protocols - up to 3,000 words
Authors should make a case to the Editor-in-Chief for publication of the protocol. Study protocols that include an intervention are required to be registered should include the trial registration number and indicate when the findings are due to be reported.

CONSIDERATIONS BEFORE SUBMISSION

Open access

Authors can choose whether to publish their paper as Open Access. The open access publication fee for this journal is USD 1700, excluding taxes. There is a 20% discount off the open access publication fee for members of the Australian College of Critical Care Nurses (the College). The College member price is USD 1360, excluding taxes. Please visit our Open Access page for more information. Learn more about Elsevier's pricing policy: https://www.elsevier.com/openaccesspricing.

Human rights

The author must ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans https://www.wma.net/policies-post/wma-declaration-of-helsinki-ethical-principles-for-medical-research-involving-human-subjects/ and adheres to the uniform Requirements for manuscripts submitted to Biomedical journals http://www.icmje.org.

All studies must be conducted to the highest ethical standard in accordance with local regulations and standards for gaining ethical approval/clearance. Authors should include a statement in the methods section of the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed. The approving body and (if relevant) approval number should be provided within the paper. On initial submission please redact this information to enable blind peer review. Evidence of ethical approval, or waiver thereof, must be provided at the time of manuscript submission. To provide this evidence, authors are required to upload a letter of ethical approval (or waiver) from the granting institution. This should be uploaded using the file type 'Ethical Statement' so that the document is not made available to peer reviewers. Any waiver of ethical approval must be independently determined. Authors are not permitted to make a determination about whether ethical approval is required or not. If national guidelines provide information on waiver of ethical approval, this information must be provided to the Editor-in-Chief at the point of submission and a statement to this effect included within the methods section of the manuscript. For information on Ethics in Publishing and Ethical guidelines for journal publication see https://www.elsevier.com/authorethics and https://www.elsevier.com/ethicalguidelines.

Authorship

All authors should have made substantial contributions to all of the following: (1) the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work, AND (2) drafting the article or revising it critically for important intellectual content, AND (3) final approval of the version to be submitted, AND (4) 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. You must make a true statement that all authors have approved the final article, agree to be accountable for all aspects of the work and acknowledge that all those entitled to authorship are listed as authors. Sample text of an Author Agreement Statement can be downloaded here.

We ask that roles for each and every author be individually described, with reference to the criteria for authorship. For transparency, we encourage authors to submit an authorship statement on the title page outlining their individual contributions to the paper using the relevant CRediT roles: Conceptualisation; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualisation; Roles/Writing - original draft; Writing - review & editing. Authorship statements should be formatted with the names of authors first and CRediT role(s) following. More details and an example are provided here.

All those individuals who provided help during the research (e.g. collecting data, providing language help, writing assistance or proofreading the article, etc.) who do not meet criteria for authorship should be acknowledged in the paper with their permission. Please include relevant information about acknowledgments on the Title Page. Any acknowledgements should be listed additionally, as described above.

Changes to authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, 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. Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.

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, a published lecture or academic thesis, see 'Multiple, redundant or concurrent publication' for more information), 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 service Crossref Similarity Check.

Other/multiple and parallel publications

The journal seeks to publish original papers that make a substantial innovative contribution. Generally, the ample word limits provided by Australian Critical Care permit authors to publish all aspects of a study within a single paper. We do recognise that larger studies are often complex and lend themselves to more than one publication. In order to aid editorial decisions about distinctiveness and to avoid inadvertent duplication please upload copies of all previous, current and under review publications from this study. All published and in press accounts of a study from which data is referred to in a manuscript, and any relationship between information presented and other publications from the same study, must be made clear. This includes any version of the manuscript which may be previously published on a pre-print server (for example, MedRxiv). It is not sufficient to simply cite a prior publication - the text must state that results are from the same study. Citation of publications 'in press' is acceptable, provided that full details are given, including the DOI if available. Citations in manuscripts under review must be blinded to preserve the peer-review process. Please mark such citations as "Blinded for peer review". On acceptance the full details of the reference must be included. If other publications are under review or in preparation this should be mentioned in your letter to the editor and you should give an undertaking that you will take all possible steps to ensure subsequent publications contain a reference to your publication in Australian Critical Care if you are successful. The study should be referred to by a distinctive name which will be used in any future publications to identify that it is the same study.

Use of inclusive language

Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Content should make no assumptions about the beliefs or commitments of any reader; contain nothing which might imply that one individual is superior to another on the grounds of age, gender, race, ethnicity, culture, sexual orientation, disability or health condition; and use inclusive language throughout. Authors should ensure that writing is free from bias, stereotypes, slang, reference to dominant culture and/or cultural assumptions. We advise to seek gender neutrality by using plural nouns ("clinicians, patients/clients") as default/wherever possible to avoid using "he, she," or "he/she." We recommend avoiding the use of descriptors that refer to personal attributes such as age, gender, race, ethnicity, culture, sexual orientation, disability or health condition unless they are relevant and valid. When coding terminology is used, we recommend to avoid offensive or exclusionary terms such as "master", "slave", "blacklist" and "whitelist". We suggest using alternatives that are more appropriate and (self-) explanatory such as "primary", "secondary", "blocklist" and "allowlist". These guidelines are meant as a point of reference to help identify appropriate language but are by no means exhaustive or definitive.

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 https://www.elsevier.com/funding.

Declaration of interest

All authors must disclose any financial and personal relationships with other people or organisations that could inappropriately influence (bias) their work. Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors must disclose any interests in two places: 1. A summary declaration of interest statement should be included in the title page file. If there are no interests to declare then please state this: 'Declarations of interest: none'. This summary statement will be ultimately published if the article is accepted. 2. Detailed disclosures as part of a separate Declaration of Interest form, which forms part of the journal's official records. It is important for potential interests to be declared in both places and that the information matches.

Queries

For questions about the editorial process (including the status of manuscripts under review) or for technical support on submissions, please visit our Support Center.

Article Preparation

All submissions are to follow the structure for papers submitted to Australian Critical Care as listed below. A manuscript template has been developed to assist you with developing your manuscript and can be accessed here.

Manuscript Text
Font size of 11 or 10 pt, double-spaced, margins 2.5 cm (or 1 inch), and numbered pages. Please do not include line numbers in your manuscript as these will be inserted during the submission process.

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: https://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.

When writing your manuscript please avoid the use of abbreviations unless they are likely to be widely recognised. In particular, you should avoid abbreviating key concepts in your paper where readers might not already be familiar with the abbreviation. Any abbreviations which the authors intend to use should be written out in full and followed by the letters in brackets the first time they appear, thereafter only the letters without brackets should be used. Do not include a separate list of abbreviations.

Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

The following resources may assist you when developing your manuscript.

Elsevier Researcher Academy

Researcher Academy is a free e-learning platform designed to support early and mid-career researchers throughout their research journey. The "Learn" environment at Researcher Academy offers several interactive modules, webinars, downloadable guides and resources to guide you through the process of writing for research and going through peer review. Feel free to use these free resources to improve your submission and navigate the publication process with ease.

Language Services

Please write your text in good English (the journal publishes in British English but manuscripts can be submitted in either American or British English). Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Elsevier's Author Services.

Main Manuscript



Background

Objectives

Methods

Provide sufficient details to allow the work to be reproduced by an independent researcher. The appropriate reporting guidelines should be followed (see https://www.equatornetwork.org) and referenced. Methods that are already published should be summarised and indicated by a reference. If quoting directly from a previously published method, use quotation marks and also cite the source. Any modifications to existing methods should also be described. The trial or review protocol registration number should be inserted into the Methods section but redacted for the purpose of blind peer review.

Statistical analysis should be reported in the methods. Standard methods of presenting statistical material should be used. Where methods used are not widely recognised explanation and full reference to widely accessible sources must be given. Exact p values should be given to no more than three decimal places. Please refer to and follow the SAMPL guidelines for statistical reporting which are available on the EQUATOR NETWORK website (https://www.equator-network.org/2013/02/11/sampl-guidelines-for-statistical-reporting/) and review the following ACC Editorial (https://www.australiancriticalcare.com/article/S1036-7314(20)30028-X/abstract) when writing the statistics section of your manuscript.

Wherever possible give both point estimates and confidence intervals for all population parameters estimated by the study (e.g. group differences, frequency of characteristics).

Identify the statistical package used (please note that SPSS has not been "Statistical Package for the Social Sciences" for many years). All statistical packages should be appropriately referenced in text (e.g. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) and in the reference list (e.g. IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.

Results/ Findings

Results should be clear and concise.

Discussion

This should explore the significance of the results of the work, not repeat them. Avoid extensive citations and discussion of published literature. Limitations should be noted.

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.

Tables

There should be no more than five tables and figures in total and included in a separate file. All tables and figures should be clearly labelled and avoid using bold lettering. Tables should be uploaded in the original application. Do not imbed Tables as images. If your manuscript includes more than five tables in total, or for very large tables, these can be uploaded as Supplementary Material and will be included as such in the online version of your article. 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.

Figures

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.
• Ensure that color images are accessible to all, including those with impaired color vision.

A detailed guide on electronic artwork is available.
You are urged to visit this site; some excerpts from the detailed information are given here.
Formats
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is' in the native document format.
Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, 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 (or PDF): Vector drawings, embed all used fonts.
TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.
TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi.
TIFF (or JPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.
Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Color Artwork

Figures/illustrations can be published in color at no extra charge for the online version. For the print version, color incurs a charge of US$ 312 for the first page and US$ 208 for every additional page containing color. If you wish to have figures/illustrations in color online and black and white figures printed, please submit both versions. If you wish to publish color illustrations and agree to pay the "color charge" check the appropriate box.

Illustration services

Elsevier's Author Services 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.

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.

References

Usually no more than three references should be used to support a single idea. Avoid citation of personal communications or unpublished material. Citations to material in press (i.e. accepted for publication) are acceptable and such references should include details of the digital object identifier (DOI). Citation of material currently under consideration elsewhere (e.g. "under review" or "submitted") is not acceptable.We encourage citation of peer-reviewed research. However, we recognise that there may be situations in which you may find it appropriate to reference research that is based on material not yet fully written as a formal manuscript, that is currently under review, or which may be available on a preprint server. These sources can be cited provided a qualifying statement is included which identified the limitations of the work (e.g. It has been reported that x resulted in y, however these results are at present only available as a non-peer reviewed preprint.)

All publications cited in the text should be presented in a list of references following the text of the manuscript. In text references should be listed as consecutive numbers which are superscript above the text. The full reference should be cited in a numbered list at the end of the manuscript. References should follow the National Library of Medicine's Style Guide for Authors, Editors and Publishers http://www.ncbi.nlm.nih.gov/books/NBK7256/.

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.

For journal articles published online only the Digital Object Identifier (DOI) must be included.

Data references

This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. The [dataset] identifier will not appear in your published article.

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.

Journal abbreviations source

Journal names should be abbreviated according to the Abridged Index Medicus (AIM or "Core Clinical") Journal Titles.

Supplementary Material

Supplementary material such as applications, images, and sound clips, can be published with your article to enhance it. Supplementary files should be identified in the main text of the manuscript (e.g. Supplementary File 1). Submitted supplementary items are published exactly as they are received (Excel or PowerPoint files will appear as such online). Please submit your material together with the article and supply a concise, descriptive caption for each supplementary file. If you wish to make changes to supplementary material during any stage of the process, please make sure to provide an updated file. Do not annotate any corrections on a previous version. Please switch off the 'Track Changes' option in Microsoft Office files as these will appear in the published version.

The submission process

Manuscripts are submitted via Editorial Manager which can be accessed via https://www.editorialmanager.com/aucc/default1.aspx. To avoid unnecessary delay authors should carefully review their manuscript against the Guide for Authors and the submission checklist which can be accessed here.

The review process

This journal operates a single-blind review process. With the exception of Clinical Trials Registration Numbers, no identifying information should be included in the manuscript. This includes identification of the institution at which the research was conducted, citations to authors' previous publications, or author initials to indicate contribution to the work. On acceptance this information must be included at the copyediting stage.

All contributions will be initially assessed by the Editor-in-Chief for suitability for the journal. Papers deemed suitable are then sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. Letters to the Editor and Editorials will have one peer review conducted by a member of the Editorial Committee. The Editor-in-Chief is responsible for the final decision regarding acceptance or rejection of articles. The Editor-in-Chief's decision is final.

Papers which do not meet basic standards or are unlikely to be published irrespective of a positive peer review, for example because their novel contribution is insufficient or the relevance to the discipline is unclear, may be rejected at this point to avoid delays to authors who may wish to seek publication elsewhere. Occasionally a paper will be returned to the author with requests for revisions to assist the editors in deciding whether to send it out for review. Authors can expect a decision from this stage of the review process within 2-3 weeks of submission.

Manuscripts going forward to the review process are reviewed by members of an international expert panel. All such papers will undergo a single-blind peer review by two or more reviewers. We take every reasonable step to ensure author identity is concealed during the review process. We aim to complete this process within 8 weeks of the decision to review although occasionally delays do happen, and authors should allow at least 12 weeks from submissions before contacting the journal. In submitted revisions of the original manuscript you will need to provide clear evidence of the changes within the manuscript by either highlighting the changes or changing the text to a coloured font. Please do not use track changes. Response to reviewer comments should also be included in table format specifying the nature of change or reasoning as to why this change was not undertaken.

RESEARCH DATA
This journal encourages and enables you to share data that supports your research publication where appropriate, and enables you to interlink the data with your published articles. Research data refers to the results of observations or experimentation that validate research findings. To facilitate reproducibility and data reuse, this journal also encourages you to share your software, code, models, algorithms, protocols, methods and other useful materials related to the project. Below are a number of ways in which you can associate data with your article or make a statement about the availability of your data when submitting your manuscript. If you are sharing data in one of these ways, you are encouraged to cite the data in your manuscript and reference list. Please refer to the "References" section for more information about data citation. For more information on depositing, sharing and using research data and other relevant research materials, visit the research data page.

Data linking
If you have made your research data available in a data repository, you can link your article directly to the dataset. Elsevier collaborates with a number of repositories to link articles on ScienceDirect with relevant repositories, giving readers access to underlying data that gives them a better understanding of the research described. There are different ways to link your datasets to your article. When available, you can directly link your dataset to your article by providing the relevant information in the submission system. For more information, visit the database linking page. For supported data repositories a repository banner will automatically appear next to your published article on ScienceDirect. In addition, you can link to relevant data or entities through identifiers within the text of your manuscript, using the following format: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).

Mendeley Data This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols, and methods) associated with your manuscript in a free-to-use, open access repository. During the submission process, after uploading your manuscript, you will have the opportunity to upload your relevant datasets directly to Mendeley Data. The datasets will be listed and directly accessible to readers next to your published article online.

For more information, visit the Mendeley Data for journals page.

Data Statement

To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.

Online proof correction

To ensure a fast publication process of the article, we kindly ask authors to provide us with their proof corrections within two days. Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is like MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors. If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF. We will do everything possible to get your article published quickly and accurately. 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. 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. Please note, that for consistency of style some editorial corrections may be made after you have undertaken the online proof correction.

Offprints

The corresponding author will, at no cost, receive a customized Share Link providing 50 days free access to the final published version of the article on ScienceDirect. The Share Link can be used for sharing the article via any communication channel, including email and social media. 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 Author Services. Corresponding authors who have published their article gold open access do not receive a Share Link as their final published version of the article is available open access on ScienceDirect and can be shared through the article DOI link.
