1. Before you begin
Acadlore fully adheres to the Code of Conduct and Best Practice Guidelines of the Committee on Publication Ethics (COPE). Our editors have zero tolerance for publication ethics issues, such as plagiarism, data falsification, and inappropriate authorship credit, to name but a few. Authors wishing to publish articles in our journals are expected to comply with the best practices of ethical publication:
a) Submit the same manuscript to one journal only.
b) Disclose any fact that may lead to a conflict of interest in the manuscript.
c) Present the research findings accurately, and highlight their significance objectively.
d) Provide enough details on the data and methods, allowing others to replicate and build on published results.
e) Deposit raw data publicly before submission, or at least present the raw data to the reviewers and editor.
f) Ensure the originality of your manuscript and avoid plagiarism:
- Acadlore does not tolerate any form of plagiarism. Others’ work and/or words cannot be used without explicit citation or quotation. Any text, image, data, or idea borrowed from others’ work or even your previous work must be credited to the original source. We reserve the right to screen for unoriginal material through appropriate plagiarism checking tools, e.g., CrossRef and iThenticate. If plagiarism is detected during the peer review, the manuscript will be rejected; if plagiarism is detected after publication, we will launch an investigation and may retract the publication.
g) Do not manipulate images in any way that causes misinterpretation of the information in the original image:
- Do not add, enhance, or remove features from the original image; Do not enhance or obscure some information of the original image by modifying the contrast, brightness, or color balance.
Please refer to Acadlore publication ethics for more details.

Please submit with the manuscript, the names and emails of three potential reviewers with the appropriate expertise to review the manuscript. The suggested reviewers should not be collaborators of the co-authors. You may suggest reviewers from among the authors that you frequently cite in your paper. The journal editor retains the sole right to decide whether to use the suggested reviewers.
During the submission, you are required to add a concise cover letter with the article. The cover letter should preferably provide the following information:
a) The significance of the research contents.
b) The findings placed in the context of previous works.
c) The fitness of the article to the journal.

a) Author name and title.
b) Degree received, year of graduation, and institution information.
c) Work experience.
d) Research directions.
e) Memberships of professional societies and awards received.
a) Preliminary assessment
Once submitted, the article is received by a professional managing editor, who will decide whether the article meets the publication ethics, fits the scope of the journal, and is scientifically sound. The decision will be made in consultation with experts in relevant fields. If the article is deemed as suitable, it will be sent for peer review. Otherwise, it will be rejected, or returned to the authors for revision and resubmission.
b) Peer review
Once the article passes the initial assessment, it will be peer reviewed by at least two independent reviewers selected by our academic editor, with the help from a dedicated in-house assistant editor. The reviewers are preferably experts in the relevant fields. Potential reviewers suggested by the authors may also be considered. The reviewers must be independent from the authors and their institutions, qualified for evaluating the technical aspects of the article, and available to evaluate the article within the required period. The peer review will be double blind, where the authors and reviewers do not know the identities of each other.
c) Review decisions
Every article published in Acadlore journals go through a peer review by at least two reviewers. Review decisions are made by the academic editor, according to the reviewer comments on each article. The dedicated in-house assistant editor will communicate, via our own manuscript processing system, the review decision on your submission, which will be one of the following:
The article is accepted without any further revision. The chance of direct acceptance is extremely rare.
- Accept after minor revision:
The article will be accepted for publication in principle, after it is properly revised according to the reviewer comments. The revised article will not be sent to the reviewers again. The dedicated in-house editor will check if the revision is satisfactory, and the revised article meets the formal requirements. Five days are given for minor revisions.
- Accept after major revision:
The article will have a good opportunity of being accepted for publication, after it is significantly modified according to the reviewer comments. The authors need to respond to the comments point by point, or provide a clear response if they disagree with some comments. Normally, only one round of major revision is allowed. The revised article will be sent to the reviewers for another round of review. The major revisions should be completed within a suitable period.
The article is rejected due to the technical objections raised by the reviewers, e.g., the lack of contribution of the research contents. The rejection is final and cannot be reversed.
Once accepted, the article will be copy-edited by our subeditors to maximize its clarity and enhance its value. The copy-edited version will undergo author proofreading, final corrections, and publication on the www.acadlore.com website.
To expedite copy-editing and publication, authors are encouraged to use the LaTeX template or MS Word template of this journal to prepare their manuscript. The text should be in single-column format. To avoid unnecessary errors, you are strongly advised to use the "spell-check" and "grammar-check" functions of your word processor. Please insert the figures into the main text close to their first citation. The manuscripts prepared in MS Word must be converted into a single file before submission. Please note that using the LaTeX template may require more time for learning and configuration, but it can provide higher quality typesetting and better support for mathematical formulas. While we recommend using the LaTeX template, it is not mandatory and authors may also use the MS Word template for their convenience. Please be aware that during the production stage, our in-house editors will be performing LaTeX typesetting for the final version of the article.
Graphical abstract is a single image designed to help the reader to quickly gain an overview of the article, and ascertain the purpose and results of the work. It could either be the concluding figure from the article, or better still a figure that is specially designed for the purpose in an attention-grabbing way. Note that the graphical abstract must be original and unpublished, without any postage stamps, currency, or trademarked items.
a) The graphical abstract should be sufficiently clear with the width to height ratio of 2:1. The size of the graphical abstract should not exceed 500K.
b) The texts in the graphical abstract should be clear and easy to read, using Times, Arial, or Courier font with a large enough font size.
c) No additional text, outline or synopsis should be included. Any text or label must be part of the image file.
The title should be concise, specific, and informative. Titles are often used in information-retrieval systems, Avoid acronyms, abbreviations, punctuation, or formulae.
The forename and surname of each author must be provided. The initials of any middle names can be added. Complete address information including zip code, city, state/province, and country. Designate one author as the corresponding author, who will handle correspondence at all stages of refereeing and publication, also post-publication, and put his/her email, preferably institutional email, at the end of the affiliation section. One corresponding author is preferred for each manuscript; No more than two corresponding authors are allowed. Please also provide the ORCID of each author.
The Abstract should be a single paragraph of up to 300 words, which does not have references, and does not contain any non-essential abbreviations or acronyms. We encourage authors to follow the style of structured abstracts, but without headings:
(1) Purpose: Place the research question in a broad context, and highlight the research purpose;
(2) Methodology: Describe the main methods applied in the article briefly;
(3) Results: Sum up the main results of the article;
(4) Conclusions: Present the main conclusions or interpretations of the results;
(5) Implications: Briefly explain how the findings contribute to the research question. Do not include results which are not presented and substantiated in the main text or exaggerate the main conclusions. An abstract is often presented separate from the article. It must be able to stand alone.
List five to eight common keywords in the subject discipline, which are specific to the article. These keywords will be used for indexing purposes.
The Introduction section should place the study briefly in a broad context, and clearly define its purpose and importance, including the specific hypotheses being tested. Plus, the current state of the research field should be reviewed carefully, and supported by relevant publications. In addition, the main aim, methodology, and conclusions of the work should be summed up in a concise thesis statement. This section should be written in language that will be comprehensible to readers working outside the topic.
The Methodology section should be written concisely, yet provide enough details to allow others to replicate and build on published results. The well-established methods can be introduced briefly with proper citations. Do not describe these published methods in details. In contrast, detailed descriptions are required for new methods.
The Results section should describe the results concisely and precisely, provide their interpretation, and draw possible conclusions from the results.
The Discussion section should interpret the results in perspective of previous studies and the working hypotheses, and report the research findings and implications in the broadest context possible. Avoid extensive citations and discussion of published literature.
The Conclusions section should clarify the main conclusions of the research, highlighting its significance and relevance. The limitations of the work and the directions of future research may also be mentioned. Please contain nothing not substantiated in the main text.

If there is more than one appendix, they should be identified as A, B, etc. Equations in appendices should be given separate numbering: Eq. (A1), Eq. (A2), etc.; in a subsequent appendix, Eq. (B1) and so on. Similarly for tables and figures: Table A1; Figure A1, etc. All appendices must be cited in the main text.
You can flexibly use tenses, provided that they are proper and clear. Several tenses can appear in the same sentence. As a general guide, the past tense is preferred for the authors' actions, and research results, the present tense is preferred for the title, narrations, and results analysis, and the future tense is preferred for predictions of future research trends.
Acronyms/Abbreviations/Initialisms should be defined the first time they appear in each of three sections: the Abstract; the main text; the first figure or table. When defined for the first time, the acronym/abbreviation/initialism should be added in parentheses after the written-out form. Ensure consistency of abbreviations throughout the article.
All the physical quantities and units of measurement in the paper must comply with the International System of Units (SI) and their abbreviations should be used. Imperial, US customary and other units should be converted to SI units whenever possible.
Wherever the application domain uses a different set of units widely, please minimize the use of non-standard units or non-standard symbols for those units. Please leave a regular space or non-breaking space between each value and the measurement unit. The authors are encouraged to render the numbers specifying the dot as a decimal separator, and the comma as a thousand separator, e.g., 1,000,000.
You are strongly recommended to use MathType or Microsoft Equation Editor to edit equations. Equations should be editable rather than appear in a picture format.
Figures and tables
Create tables using Microsoft Word embedded functions or export Microsoft Excel tables. Do not create tables by hand using multiple spaces or tabs. The size of each figure should not exceed 500K. Authors are strongly recommended to divide each figure into no more than four subgraphs.
All figures and tables should be inserted into the main text close to their first citation, and must be numbered following their order of appearance (Figure 1, Figure 2, etc.; Table 1, Table 2, etc.).
A short, explanatory caption should be placed directly below each figure. Each table must have a descriptive, short, one-line title. Note that citation is not allowed in either figure caption or table title. Reference each table and figure within the text as Table 1 or Figure 1. Ensure that the caption/title is on the same page with the figure/table.
Authors are encouraged to prepare figures in color (RGB at 8-bit per channel). There is no additional cost for online publication of full color graphics. It would be even better if you also submit suable black-and-white versions of all the color figures to avoid technical complications that may arise by converting color figures into grayscale figures (for the printed version).

3. After acceptance
Use of DOI
The Digital Object Identifier (DOI) is a unique string of characters used to cite and link to electronic documents. The DOI assigned to an online document published by Acadlore never changes. Therefore, it is an ideal way to use the DOI to create a URL hyperlink to your published article.
One set of page proofs will be emailed to the corresponding author, or a link will be provided in the email for him/her to download the files themselves. You may mark the corrections in the files, or list the corrections clearly point by point. Please focus on the typesetting, editing, completeness, and correctness of the text. At this stage, significant changes to the article are not allowed. Please send back your corrections in one communication to help us catch up with the publishing schedule. Acadlore may proceed with the publication of your article, if no response is received.
The corresponding author will be provided with a file of the published article via email. If he/she opts for paper offprints, he/she must indicate this preference to the journal editor once the article is accepted. The paper offprints will incur an extra charge.
