Corrections, Retractions, and Editorial expressions of concern Policies

Samara university journals are committed to uphold the integrity of the literature and publishes Errata (Corrections), Expressions of Concerns or Retraction Notices dependent on the situation and in accordance with the COPE Retraction Guidelines. In all cases, these notices are linked to the original article.

When an author discovers a significant error or inaccuracy in his/her own published work, it is the authors obligation to promptly notify the journal editor or publisher and cooperate with the editor to retract or correct the paper.

If the editor or the publisher learn from a third party that a published work contains a significant error, it is the obligation of the author to promptly retract or correct the paper or provide evidence to the editor of the correctness of the original paper.

When errors are identified in published articles, the publisher will consider what action is required and may consult the editors and the authors’ institution(s). 

Errors by the authors may be corrected by a corrigendum, and errors by the publisher — by an erratum (see more).

If there are errors that significantly affect the conclusions or there is evidence of misconduct, this may require retraction or an expression of concern following the COPE Retraction Guidelines. All authors will be asked to agree to the content of the appropriate notice.

CrossMark Policy

The Samara university is the publisher for several journals and is committed to maintaining the integrity and completeness of the published scholarly records and demonstrates this commitment by participating in CrossMark. 

CrossMark is a multi-publisher initiative to provide a standard way for readers to locate the authoritative version of an article or other published content. By applying the CrossMark logo, Samara university is committing to maintaining the content it publishes and to alerting readers to changes if and when they occur.

Clicking the CrossMark logo on a document will tell you its current status and may also give you additional publication-record information about the document.

The Samara university journals content that will have the CrossMark logo is restricted to current and future journal content and is limited to specific publication types (see below). Articles in Press will not have the CrossMark icon for the present.
