Publication Ethics and Malpractice Statement

ALCHEMY Jurnal Penelitian Kimia (p-ISSN: 1412-4092; e-ISSN: 2443-4183) is a peer-reviewed journal published by Universitas Sebelas Maret. This statement defines the ethical responsibilities of authors, editors, reviewers, and the publisher before, during, and after publication, including special issues. It is informed by Committee on Publication Ethics (COPE) guidance and the ACS Ethical Guidelines to Publication of Chemical Research.

Responsibilities of Authors and Authorship

Authors must report their research accurately, explain its limitations, and take responsibility for all submitted content, including work performed by third-party laboratories or service providers. Every author must make a substantial contribution to the research, participate in drafting or critical revision, approve the final manuscript, and accept accountability for their contribution and the resolution of integrity concerns. 

Guest, honorary, purchased, fictitious, and undisclosed authorship are prohibited. The corresponding author must obtain all authors' approval of submission and revisions. Contributions must be described using CRediT; other contributors should be acknowledged with their permission. Authorship changes require written justification, agreement from all affected authors, and editorial approval. Unresolved disputes may be referred to the relevant institutions.

For the CRediT role definitions, contribution-statement example, and acknowledgment requirements, see Authorship and Contributorship. Permitted AI assistance and the corresponding disclosure requirements are detailed in AI Tools Usage Policy in Article Preparation.

Authors must disclose funding, the funder's role, and financial or non-financial competing interests, including an explicit declaration when none exist. Authors must promptly report significant errors and cooperate in correcting the record.

Definitions, disclosure requirements, and procedures for handling competing interests among authors, reviewers, editors, and the publisher are provided in the Conflict of Interest policy.

Responsibilities of Editors

Editors must assess manuscripts fairly on scientific merit, relevance, and compliance with journal requirements, without discrimination or commercial influence. They must protect confidentiality, appoint suitable reviewers, communicate reasoned decisions, and address credible ethical concerns. Editors must not exploit unpublished information or demand irrelevant citations.

Editors must disclose competing interests and withdraw from handling their own submissions or work involving relationships that compromise impartiality. Such manuscripts require independent editorial handling. Guest editors follow the same standards, and the Editor-in-Chief retains oversight of special issues. These responsibilities follow the principles described in the ACS ethical guidelines for editors.

Peer Review and Responsibilities of Reviewers

ALCHEMY applies single-anonymized (single-blind) peer review: reviewers know the authors' identities, while reviewer identities are withheld from authors. Manuscripts passing initial editorial assessment are evaluated by at least three independent reviewers. Editors make publication decisions based on the reports and their own assessment. Special issues follow the same standards.

Reviewers must have appropriate expertise, meet agreed deadlines, disclose competing interests, and provide objective, constructive, evidence-based reports. They must keep submissions and review materials confidential, obtain editorial permission before involving another person, and avoid using unpublished information for personal advantage. Suspected irregularities must be reported privately to the editor. Reviewer impersonation, fabricated reports, collusion, and coercive citation are prohibited. Reviewer conduct is guided by the COPE Ethical Guidelines for Peer Reviewers.

Responsibilities of the Publisher

Universitas Sebelas Maret supports editorial independence, confidential handling of submissions, fair investigation of ethical concerns, and preservation of the scholarly record. Publication fees, advertising, and sponsorship must not determine acceptance. The publisher assists editors in implementing corrections and other notices and arranging independent oversight when necessary. These duties are informed by the Principles of Transparency and Best Practice in Scholarly Publishing.

The institutional arrangements for editorial independence are described in Ownership and Management, while the separation of advertising and sponsorship from editorial decisions is explained in the Advertising Policy.

Originality, Plagiarism, and Citation Integrity

Fabrication, falsification, plagiarism, duplicate submission, redundant publication, and misleading fragmentation of results are prohibited. Authors must disclose related manuscripts and earlier dissemination, including preprints, theses, and conference publications, for editorial assessment. Reused material requires appropriate attribution and necessary permission. References must be relevant and verifiable; citation manipulation is unacceptable.

Manuscripts are screened using Turnitin or an equivalent service before review and before publication. The journal's 20% similarity threshold is a screening criterion requiring assessment of the sources and nature of overlap. A lower score does not establish originality, and a higher score alone does not establish misconduct. Editors may request clarification or revision, or reject manuscripts with substantial ethical problems. Relevant principles are described in the ACS ethical obligations of authors.

The screening stages, originality requirements, self-plagiarism provisions, and possible consequences are explained further in the Plagiarism Policy. These operational provisions complement the ethical principles stated here.

Data Reproducibility and Integrity of Figures

Authors must retain the original evidence supporting their findings and provide it for justified editorial requests, subject to explained restrictions. A Data Availability Statement must identify access to supporting data and code, or explain restrictions and access procedures. Repository deposition is encouraged, consistent with the principles of the ACS Research Data Policy.

Methods must permit assessment and reproduction. Chemistry studies require suitable evidence of substance or material identity, purity, and composition. Relevant spectra, chromatograms, diffraction data, microscopy records, and computational inputs should support the reported claims. Computational studies must identify software, essential parameters, and validation. Measured and predicted results must be distinguished. See the RSC guidance on experimental reporting.

Data exclusions and processing affecting interpretation must be explained. Figures must accurately represent their evidence. Fabricating features, hiding signals, or presenting duplicated images as different experiments is prohibited. Cropping, composites, and reuse must be identified, and original files retained.

Research Ethics and Chemical Safety

Research involving humans, identifiable human materials or data, or animals must obtain appropriate ethical approval before the work begins, where required. Manuscripts must identify the approving body and approval reference and report informed consent, an authorized waiver, or a justified exemption. Identifiable information requires appropriate protection and consent for publication.

Relevant research must follow the Declaration of Helsinki or suitable animal-welfare standards, including ARRIVE. Authors must document necessary sampling and material-use permissions and disclose unusual hazards, relevant precautions, environmental safeguards, and substantial risks of harmful misuse, following the principles in RSC author guidance on safety and research ethics.

For the reporting and investigation of suspected ethical breaches, see Allegation of Research Misconduct. Complaints about editorial conduct and appeals against decisions are addressed in Complaints and Appeals. Scholarly comments after publication are covered by Post-publication Discussions, while formal changes to the publication record are governed by Correction and Retraction.

Allegation of Research Misconduct

ALCHEMY Jurnal Penelitian Kimia is committed to maintaining the accuracy and integrity of the scholarly record by addressing allegations of research misconduct fairly and transparently. Research misconduct includes fabrication, falsification, citation manipulation, plagiarism, and other serious ethical violations in conducting, reviewing, or reporting research.

Allegations of suspected research misconduct should be submitted to alchemy@mipa.uns.ac.id, identifying the manuscript or published article, the nature of the concern, supporting evidence, and any relevant competing interests. Specific and credible anonymous reports will also be considered.

All allegations will be assessed impartially by the Editors or an appropriately independent representative in accordance with relevant COPE guidelines and flowcharts. The initial assessment involves validating the allegations, determining whether they constitute research misconduct, and identifying potential conflicts of interest.

The disclosure and recusal requirements supporting impartial assessment are detailed in the Conflict of Interest policy. Concerns involving textual overlap or inappropriate AI use should also be read alongside the Plagiarism Policy and AI Tools Usage Policy in Article Preparation, respectively.

When credible evidence of potential misconduct is identified, the corresponding author will be contacted and requested to provide a detailed explanation on behalf of all coauthors. The Editors may seek independent expert opinions, involve the Editorial Board, or refer the matter to the relevant institution for formal investigation. Institutions are responsible for investigating research misconduct within their jurisdiction, while the journal retains responsibility for editorial decisions and maintaining the integrity of the publication record.

Editorial actions will depend on the findings and severity of the misconduct. Manuscripts confirmed to involve serious misconduct may be rejected. For published articles, appropriate measures may include corrections, retractions with replacement, or retractions, depending on the circumstances and applicable publication ethics guidelines. Where misconduct is not substantiated, additional explanations, analyses, or corrections may be sufficient. Any published notices will be linked to the original article to ensure transparency.

The grounds for corrections and retractions, the content of formal notices, and preservation of the affected article are explained further in Correction and Retraction.

Throughout the process, confidentiality will be maintained to the extent reasonably possible, relevant parties will be informed of the outcomes, and appropriate records will be retained. Withdrawal of a manuscript does not necessarily terminate an ongoing ethical investigation.

Complaints about the handling of a case or appeals against an editorial decision should follow Complaints and Appeals. That policy complements the investigation procedures described here.

Complaints and Appeals

ALCHEMY Jurnal Penelitian Kimia is committed to providing a fair, transparent, and impartial mechanism for addressing complaints and appeals concerning editorial decisions, peer review procedures, publication processes, and the conduct of editorial personnel.

Complaints and appeals should be submitted to alchemy@mipa.uns.ac.id, clearly identifying the manuscript or published article, the nature of the complaint or appeal, specific reasons, supporting evidence, and any relevant competing interests. Complaints submitted in good faith will be handled without retaliation, and credible anonymous complaints will be considered where sufficient information is provided.

Complaints will be assessed by the Editors or an appropriately independent representative. Complaints involving an Editor or the publisher will be referred for independent assessment to prevent conflicts of interest. The journal may request explanations from relevant parties, consult independent experts, or seek institutional assistance where necessary, following applicable COPE guidance.

The disclosure and recusal requirements that support independent assessment are set out in the Conflict of Interest policy.

Authors who disagree with an editorial decision may submit an appeal supported by specific reasons and relevant evidence. Appeals will be reviewed impartially, considering the original decision, reviewers' comments, editorial assessments, and any additional information provided. An appeal does not automatically guarantee reconsideration or reversal of the original decision.

Any editorial actions or submission restrictions resulting from complaints must be evidence-based, proportionate, and open to appeal. Restrictions, where imposed, will have a clearly defined duration and justification.

Throughout the process, confidentiality will be protected to the extent reasonably possible. Relevant parties will be informed of the outcomes, and appropriate records will be maintained to ensure accountability and transparency.

Where a complaint raises suspected fabrication, falsification, plagiarism, or another research-integrity concern, the reporting and investigation procedures are described in Allegation of Research Misconduct. Any resulting correction or retraction of published work should also be read alongside Correction and Retraction. These policies complement the complaint and appeal mechanism described here.

Post-publication Discussions

The journal recognizes that scholarly discourse continues beyond publication. The journal encourages constructive and respectful discussion of published articles as a means to advance understanding, clarify findings, and refine knowledge in accordance with its focus and scope. Consistent with COPE’s core practices and WAME’s guidance, post-publication discussions should contribute to the accuracy, transparency, and integrity of the scholarly record.

Readers and authors may submit letters to the editor, short commentaries, or evidence-based concerns regarding articles published in the journal. Submissions should be concise, supported by relevant evidence, and directly related to the article under discussion. All submissions will undergo editorial assessment to ensure their relevance, scholarly value, and respectful presentation. Where online commenting is available, comments may be moderated to maintain constructive discussion.

Authors of the original article will normally be given an opportunity to respond to substantive comments or critiques. Accepted commentaries and author responses may be published and linked to the original article to facilitate further scholarly exchange.

Post-publication discussions that identify material errors or concerns about research integrity will be assessed in accordance with the journal’s Corrections and Retractions policy. Depending on the nature and severity of the concerns, appropriate editorial actions may include issuing a correction, publishing an expression of concern, or retracting the article, following the COPE Retraction Guidelines.

Any resulting editorial notices must clearly identify and link to the affected article, explain the reasons for the action, and remain publicly accessible. Retracted articles will normally remain available with clear labeling to preserve the scholarly record. Authors may provide responses or clarifications, although their agreement is not required for justified editorial action.

When a discussion raises suspected research misconduct, the reporting and investigation procedures in Allegation of Research Misconduct provide further guidance. Complaints about editorial handling or appeals against decisions are addressed separately in Complaints and Appeals. These routes complement scholarly discussion and the publication-record measures described above.

Correction and Retraction

ALCHEMY Jurnal Penelitian Kimia is committed to maintaining the accuracy, integrity, and transparency of the scholarly record. Published articles may require corrections, retractions, or expressions of concern when significant errors or issues related to research integrity are identified. Authors, readers, and reviewers are encouraged to report such concerns to the Editor-in-Chief with supporting evidence. All reports will be evaluated impartially in accordance with the guidelines of the Committee on Publication Ethics (COPE) and the recommendations of the World Association of Medical Editors (WAME).

The reporting and investigation of suspected misconduct are described in Allegation of Research Misconduct. The submission and editorial assessment of scholarly comments and author responses are covered by Post-publication Discussions. Together, these policies explain how concerns may be raised and assessed before a formal notice is considered.

Corrections

Corrections will be issued when errors or omissions affect the interpretation or understanding of a published article without invalidating its principal findings or conclusions. Errors originating from authors may be addressed through a corrigendum, while errors introduced during the publication process may be addressed through an erratum.

Each correction notice will clearly describe the error and the amendments made, and will be permanently linked to the original article. Any modifications to the published article will be clearly identified to maintain transparency.

Retractions

Articles published in ALCHEMY Jurnal Penelitian Kimia may be considered for retraction under the following circumstances:

1. There is clear evidence that the findings are unreliable due to major errors (e.g., miscalculations or experimental errors), fabrication of data, or falsification (e.g., image manipulation).

2. The article constitutes plagiarism.

3. The findings have been previously published elsewhere without proper attribution, disclosure, permission, or justification, constituting redundant publication.

4. The article contains material or data used without proper authorization.

5. The article infringes copyright or involves other serious legal issues, such as defamation or privacy violations.

6. The article reports research conducted in violation of ethical standards.

7. The article was published based on a compromised or manipulated peer review process.

8. The authors failed to disclose major competing interests or conflicts of interest that could have significantly influenced the interpretation of the findings or editorial decisions.

Retraction decisions will be based on the available evidence and the need to protect the integrity of the scholarly record. A formal retraction notice will identify the affected article, specify who is retracting it, and explain the reasons for retraction, distinguishing between honest errors and research misconduct where possible. Retracted articles will ordinarily remain accessible but will be clearly marked as retracted and permanently linked to the corresponding retraction notice.

For the underlying standards relevant to plagiarism and undisclosed competing interests, see the Plagiarism Policy and Conflict of Interest policy. Complaints about the editorial handling of a correction or retraction, or appeals against an editorial decision, should follow Complaints and Appeals.

Conflict of Interest

This journal is dedicated to upholding the highest standards of transparency and ethical conduct in academic publishing. This policy provides definitions of conflicts of interest and describes procedures for addressing conflicts of interest involving authors, reviewers, editors, the journal, and the publisher, whether identified prior to or after publication. The journal adheres to the Core Practices established by the Committee on Publication Ethics (COPE).

Definition of Conflicts of Interest

A conflict of interest occurs when an individual or entity has financial, personal, professional, or academic relationships or interests that could influence or appear to influence their objectivity, integrity, or decision-making in the context of research, review, editorial work, or publication processes.

Identification of Conflicts of Interest

All participants in the publication process including authors, reviewers, editors, and others are required to disclose any potential conflicts of interest relevant to the work they are submitting, reviewing, editing, or publishing. These potential conflicts may include, but are not limited to:

Financial interests: Funding sources, stock ownership, employment, consultancy arrangements, or other financial ties related to the research.

Personal relationships: Close personal or familial relationships with individuals involved in the research or publication process.

Academic relationships: Collaborations or academic affiliations that could affect objectivity or create perceptions of bias.

Competing affiliations: Relationships with competing organizations that might have conflicting interests in the research or its outcomes.

Intellectual property: Ownership of patents, copyrights, or intellectual property rights potentially impacted by the research or publication.

Handling Conflicts of Interest

The management will address conflicts of interest with diligence and transparency.

For Authors: Authors are required to disclose all potential conflicts of interest during the manuscript submission process. If a conflict of interest is identified after publication, authors should promptly inform the editorial board. The editorial board will address the conflict transparently and, if necessary, issue corrections or retractions.

The procedures and publication notices used to address errors or omissions in published disclosures are explained further in Correction and Retraction.

For Reviewers: Reviewers must decline invitations to review if they have conflicts of interest that could compromise their impartiality. If a conflict arises during the review process, reviewers should immediately notify the editorial board for appropriate action.

For Editors and Journal Staff: Editors and journal staff involved in the review and publication process must recuse themselves from handling submissions in which they have conflicts of interest. When uncertainty arises, the editorial board will decide on the appropriate course of action.

For Publishers: The publisher must implement policies to address potential conflicts of interest within its organization. The publisher should ensure that editorial decisions and processes are free from financial or competing interests.

Transparency and Disclosure

This journal will clearly outline its conflicts of interest policy and inform all stakeholders of the requirements for disclosure. Disclosures made by authors, reviewers, editors, and other stakeholders will be published alongside the relevant articles, reviews, or editorials to ensure transparency. Additionally, the journal will limit or restrict access to the publication process for editors, reviewers, and stakeholders who co-author articles submitted to the journal.

These disclosure and recusal provisions complement the responsibilities described in Publication Ethics and Malpractice Statement. The separation of commercial interests from editorial judgment is detailed in the Advertising Policy. Complaints involving a conflicted editor or publisher are addressed through the independent assessment provisions in Complaints and Appeals.

Plagiarism

The ALCHEMY Jurnal Penelitian Kimia takes plagiarism, self-plagiarism, and AI-generated plagiarism seriously and applies a strict policy to safeguard the originality and integrity of all published work.

Plagiarism Check

• All submitted manuscripts are screened using plagiarism detection software (e.g., Turnitin).
• The editorial team performs a similarity check twice: before the peer-review process and before final publication.
• The maximum acceptable similarity index is 20%. Manuscripts exceeding this threshold will be returned to the authors for correction and resubmission.

Originality Requirement

• Authors must submit only original manuscripts that have not been published previously and are not under consideration for publication elsewhere.
• Any form of plagiarism, including uncredited use of others’ ideas, text, or data, is strictly prohibited and will result in rejection.

Self-Plagiarism

• Authors must avoid redundant publication or extensive reuse of their previously published work.
• If parts of prior work must be reused, they should be properly cited and acknowledged.

AI-Generated Plagiarism

• Authors must not use generative AI or AI-assisted tools to produce original ideas, data, figures, or substantial text for their manuscripts.
• Generative AI may only be used for language improvement and readability with full author oversight (see link: Declaration of Generative AI policy).
• The editorial team reserves the right to screen manuscripts for inappropriate or undisclosed AI-generated content.

Consequences

If plagiarism or self-plagiarism is detected during the review or after publication, the editorial board will take appropriate action, which may include:

• Rejection of the manuscript
• Retraction of the published article (see link: Retraction)
• Notification to the authors’ institutions or funding bodies

The ALCHEMY Jurnal Penelitian Kimia upholds the highest standards of academic integrity and expects all authors to comply with ethical publishing practices. By submitting a manuscript, authors acknowledge that their work is original, free of plagiarism, and adheres to the principles of responsible research conduct.

The broader ethical duties concerning originality and citation integrity are described in Publication Ethics and Malpractice Statement. Where suspected plagiarism requires an investigation, the reporting and assessment procedures are provided in Allegation of Research Misconduct. The AI and retraction provisions linked above give additional guidance for those specific circumstances.

AI Tools Usage Policy in Article Preparation

Purpose and Scope

This policy establishes ethical standards for the use of Artificial Intelligence (AI) technologies in the preparation, review, and publication of scholarly works in ALCHEMY Jurnal Penelitian Kimia.
The journal follows COPE’s Core Practices, emphasizing integrity, accountability, and transparency in AI usage across research and publication activities.

Definition of Artificial Intelligence (AI) Tools

AI tools include, but are not limited to, large language models (e.g., ChatGPT, GPT-5, Gemini), generative AI for text, images, translation, or data analysis, and AI-assisted software for writing, paraphrasing, or visualization.
Use of such tools is acceptable only when transparent, ethical, and compliant with COPE standards.

Authorship and AI Contributions

Authors must declare any use of generative artificial intelligence (AI) or AI-assisted tools in the writing process of their manuscript at the time of submission. This policy applies only to the preparation of text and does not include the use of AI in data analysis or research methods.

1. Generative AI and AI-assisted technologies may be used only to enhance language, grammar, and readability of the manuscript.
2. Use of such tools must be under human oversight and editorial control. Authors must carefully check, revise, and approve the content, as AI-generated text may be inaccurate, incomplete, or biased.
3. Full responsibility and accountability for the article rests with the authors.
4. Generative AI or AI-assisted tools must not be listed or cited as authors or co-authors.

The contribution-statement, acknowledgment, and human-accountability requirements are described further in Authorship and Contributorship. The originality and attribution requirements that also apply to AI-assisted content are detailed in the Plagiarism Policy.

Declaration of Generative AI in Scientific Writing

A declaration must be included in a separate section before the References list as describe in the Author Guideline and Manuscript Template.

AI Use in Peer Review and Editorial Process

Editors and reviewers must not upload unpublished manuscripts or confidential content into AI tools.

AI may only be used to assist with grammar, summarization, or metadata analysis, ensuring confidentiality and data protection.
Peer review decisions must remain fully human-driven.

Transparency and Disclosure

All AI use in manuscript preparation, data analysis, or visualization must be clearly described.

The journal may request details about the tools used, including version, platform, and prompts.
Undisclosed AI use may trigger a research misconduct investigation.

Data privacy and Intellectual Property

Authors must not input confidential or copyrighted data into AI tools.

AI outputs may lack copyright protection; authors are responsible for verifying ownership and avoiding IP infringement.
The journal is not liable for legal issues from unauthorized AI use.

Generative AI in Figures, Images, and Artwork

Generative AI use in visual materials is subject to strict regulation. Figures, images, and artwork represent an essential component of the scientific record. Improper use of AI-assisted technologies may compromise accuracy, originality, and copyright compliance. Therefore, the journal establishes the following rules:

1. Authors must not use generative AI or AI-assisted tools to create, modify, or enhance images, figures, or artwork in submitted manuscripts.
2. Authors may use AI-assisted tools only when these tools form part of the research methodology (for example, biomedical imaging). In this case, authors must reportthe use clearly in the Methods section by including:
   • The name of the tool or model
   • The version and extension numbers
   • The manufacturer or source
3. Authors must not use generative AI or AI-assisted tools to produce graphical abstracts.

Ethical Oversight and Misconduct

Undisclosed or improper AI use that results in falsification, plagiarism, or misrepresentation constitutes research misconduct.
Cases will be investigated following COPE’s Ethical Oversight Guidelines, which may result in rejection, retraction, or institutional notification.

The reporting and investigation procedures are explained further in Allegation of Research Misconduct. If a concern affects an already published article, the grounds and notice procedures in Correction and Retraction also apply.

Policy Review and Updates

This policy will be reviewed annually by the Editorial Board to ensure alignment with evolving COPE and international publishing standards.
Revisions will be published on the journal’s website upon approval.

Authorship and Contributorship

To enhance transparency in scholarly publishing, ALCHEMY Jurnal Penelitian Kimia encourages authors to clearly specify the contributions made by each co-author using the CRediT (Contributor Roles Taxonomy) framework. This framework provides standardized terminology for describing individual contributions to scholarly research, as outlined below.

Each author's name or initials should be followed by the specific roles they performed. This contribution statement will be included in the published article. At least one author should be designated as the guarantor, accepting overall responsibility for the integrity of the work from its inception to publication.

Example:

FR: Conceptualization, Methodology, Software; TES: Data Curation, Writing – Original Draft; HR: Visualization, Investigation; DLA: Supervision; SDM: Software, Validation; YH: Writing – Review & Editing.

These role descriptions explain how contributions are reported. The criteria for qualifying as an author, approval and accountability duties, prohibited forms of authorship, and procedures for authorship changes are described in Publication Ethics and Malpractice Statement.

Individuals who contributed to the research but do not meet the criteria for authorship, including those providing technical assistance, funding support, general supervision, or scholarly discussion, should be acknowledged in a dedicated Acknowledgments section.

The full names and affiliations of acknowledged individuals must be provided. Authors are responsible for informing these individuals and obtaining their consent before including their names. Where research groups or institutions have contributed collectively, such as clinical investigators or supporting organizations, their contributions should be briefly described.

Any assistance provided by artificial intelligence (AI) tools, including large language models used for drafting, editing, or improving manuscript content, must be explicitly disclosed in the manuscript.

AI tools cannot be credited as authors. Human authors remain fully responsible for the originality, accuracy, integrity, and ethical compliance of all submitted content, including any material generated or modified with AI assistance.

Permitted AI uses and the required declaration are detailed in AI Tools Usage Policy in Article Preparation, while financial and non-financial competing-interest disclosures are addressed in Conflict of Interest. Errors in published authorship or disclosure information should be considered under Correction and Retraction.

Advertising Policy

ALCHEMY Jurnal Penelitian Kimia establishes this advertising policy to regulate any advertising or sponsorship activities related to the journal in order to safeguard the credibility of its scientific content.

Editorial Independence

All advertisements and sponsored content are entirely independent of editorial decisions. The editorial board does not endorse any products, services, or organizations advertised in connection with the journal. Editorial content is never influenced by commercial or financial interests.
