All references should be listed in accordance with the Harvard style. Harvard is an Â²author/dateÂ² system, so your in-text citation consists of the author(s) and year of publication. In the end, the authors should be listed in alphabetical order. For more guides, use the online information at http://guides.is.uwa.edu.au/harvard.
If using EndNote, cite according to the Author-Date style.
For Harvard in-text citation, the last name of the author(s) and the year of publication appear in parenthesis beside any quotation or paraphrase of a source.
Number of authors In-text citation example
1 author (Davis, 2019)
2 authors (Davis and Barrett, 2019)
+3 authors (Davis et al., 2019)
When you need multiple citations to appear at the same point in your text â€“ for example, when you refer to several sources with one phrase â€“ you can present them in the same set of parenthesis, separated by semicolons. List them in order of publication date.
(Gillner, et al., 2009; Uda and Creus, 2011; Greenfield and Harlow, 2014; Starus, et al., 2015).
If you cite multiple sources by the same author, which was published in the same year, it is important to distinguish between them in your citations. To do this, insert an â€˜aâ€™ after the year in the first one you reference, a â€˜bâ€™ in the second, and so on.

TPPS follows international regulations against scientific misconduct including fabrication, falsification, plagiarism, etc. Any cases of suspected misconduct will be assessed during the peer-review and publication process based on COPE Guidelines.
Plagiarism happens when someone presents works/ideas of others as his/her own, without full citation or acknowledgement. All submitted manuscripts have to be original and should have less than 20% similarity in text with other publications. Manuscripts will be checked by appropriate plagiarism checking software.
After submission, the authorship confirmation letters will be emailed to all authors. They should notify the Editorial Office if any misconduct has happened. The Editor-in-Chief or section Editors evaluate the submitted files before the peer-review process, and the manuscript will then be sent back to the author if do not have approval criteria or have plagiarism. In this step, authors can revise the manuscript and resubmit it. If they do not revise, the manuscript will be rejected.
If Editors discover any misconduct including fabrication, falsification, and plagiarism after publication, the manuscript will be withdrawn. Authors (at least the Corresponding Author) should have close collaboration and communication with the Editorial Office during the publication process and after, if needed.
According to the ICMJE recommendation, authorship is based on the following four criteria:
Therefore, all authors should make substantial contributions to all of the followings: (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.
Authorsâ€™ Agreement Form
It is mandatory that a signed Authorsâ€™ Agreement Form be sent along with the proofreading by the Corresponding Author. The authors acknowledge that the publisher has the legal right to take appropriate action against the authors for any violation of the terms and conditions as laid down in the Authorsâ€™ Agreement Form.
As part of the submission process, authors are required to check off their submission's compliance with all of the following items. Submissions may be returned to authors that do not adhere to these guidelines.
Changes to authorship
Authors should 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 can be made only before the manuscript has been accepted, only if the journal Editor approves. To request such a change, a letter from the corresponding author should be sent to the Editorial Office, containing: (a) the reason for the change in the 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 on exceptional occasions, the Editor will approve the addition, deletion, or rearranging authorsâ€™ list after the acceptance of the manuscript. The release of the manuscript will be suspended while the editor is reviewing the request. If the manuscript has already been published in an online issue, any request approved by the Editor will result in an erratum.

Ethical considerations of animals and human studies
Authors herein confirm that all human and/or animal studies undertaken are in compliance with the regulations of their institution(s) and generally accepted guidelines governing such work. In any studies that involve experiments on human subjects, work must be conducted in accordance with the Declaration of Helsinki. For the experiments on animal subjects, the compliance with National Institutes of Health Guidelines for the Human Use of Laboratory Animals should be declared in the text.
Peer-review policy (ethics and competing interest)
Invited reviewers are expected to consider the competing interests to accept the reviewing process of the manuscript. Reviewers should have no financial conflicts of interest which means that they may profit or be negatively impacted financially by the submitted research. They also should have no personal relationship or competition with the authors, also, they have not recently worked at the same institution or organization as the authors and have no current collaboration with the authors. They have not published or held grants with the authors during the last 5 years.
Post-publication discussion and correction
If authors or audiences find errors in their published article, especially errors that could affect the interpretation of data or reliability of information presented, they should notify the Editorial office by email at email@example.com.
If, after reading the guidance, authors/audiences believe a correction or retraction is necessary for their article, they should contact the journal by email at firstname.lastname@example.org.
All major errors are accompanied by a separate Erratum that provides clear details of the error and the changes that have been made to the article. This Erratum is electronically linked back to the original version. Also, a footnote on the original article displays the electronic link to the Erratum. This correction will be notified in the online issue of the journal.
Minor errors will not be accompanied by a separate Erratum. The corrected file will be replaced instead of the original version and a footnote will be added to the article detailing to the audience that the article has been corrected. Minor errors do not impact the reliability of, or the readerâ€™s understanding of, the scientific content.
Retraction will be considered if there is clear evidence that the findings are unreliable, either as a result of misconduct (e.g. data fabrication or image manipulation) or honest error (e.g. miscalculation or experimental error), or if the findings have previously been published elsewhere (redundant publication or duplicate publication). If any violation of Ethical consideration becomes evident by the Editorial office, the article will be retracted. In these situations, the â€œRetractedâ€ watermark to the published version of the article will be added.
Allegation of misconduct
If the journal receives a letter raising concerns about any scientific misconduct, such as plagiarism, fabrication, falsification, copyright or intellectual property violation, break of research ethics, authorship disagreements, conflicts of interest, or any other problematic conduct that happens either pre- or post-publication, it will be discussed in the Editorial Board forum. If this misconduct is confirmed, the editor will communicate in writing with the authors stating the details of misconduct that have been claimed against the paper. The authors are given a specified period of time to respond in writing to the allegation.
If the corresponding author does not respond and/or provide sufficient rationale for the raised concern, or if established evidence is provided to the Editor that proves an ethical or scientific violation, regardless of its severity, several corrective actions according to the Editorial Board decision will make, such as publishing an erratum, expression of concern, or retraction of the article.
The authors will be notified of the Editorial Boardâ€™s decision and they may appeal the decision by sending an appeal letter to the Editorial office through email@example.com.
Complaints and appeals
Authors or audiences can submit their complaints about the policies, procedures, or actions of the journal staff by sending an e-mail to firstname.lastname@example.org.
All received complaints and appeals will be handled by the Editorial office, and the Editor-in-Chief will finalize whether any appropriate response or decision change should be made. Re-review of the manuscript may be done. The new decision made after the final considerations of the appeal will be informed to the respected individuals, applied, and announced in the online version of publications.
