Advertising, Marketing, and Revenue Policy

1. Revenue and Advertising Policy

Prestress Technology maintains a strict separation between commercial content and scholarly content, ensuring that editorial decision-making remains independent of any commercial influence.

Revenue Sources: All publishing costs are borne by the sponsoring institution, Tongji University. The journal has no other commercial revenue sources.

Editorial Independence: Revenue generation, whether from article processing charges, corporate introductions, or other sources, has no influence on editorial decisions.

Corporate Introductions (Print Edition): The print edition of the journal publishes a limited amount of corporate introduction content, limited to relevant companies within the industry. Corporate introductions must comply with the following principles:

• Only general corporate information display (Non-advertising content)
• Completely unrelated to the scholarly manuscripts published in the same issue
• Commercial content and academic decision-making processes are completely separated to strictly ensure the fairness of academic content

Electronic Edition and Website: The electronic edition of the journal and the official website contain no form of advertising or commercial promotional content.

Transparency: All revenue sources are disclosed on the journal's website.

2. Direct Marketing and Solicitation Policy

Prestress Technology is committed to ethical and transparent marketing practices.

Prohibition of Spam Solicitation: The journal does not engage in, nor does it tolerate, the sending of unsolicited, bulk, or spam emails inviting manuscript submissions.

Legitimate Marketing Activities: Acceptable marketing activities include: calls for papers on the journal's website; promotion at academic conferences; targeted invitations to researchers with proven expertise; social media promotion through official channels.

Guest-Edited Special Issues: Special issues are organized through transparent processes. All special issue manuscripts undergo the same rigorous peer review as regular submissions.

Reporting of Spam: The journal encourages the academic community to report any suspicious email solicitations purporting to be from Prestress Technology.

Compliance: This policy aligns with COPE guidelines on ethical marketing.
