*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The main objective of this study was to investigate the suppressed journals in the 2007 to 2014 JCR editions and identify the characteristics and factors of these journals and their performance in various indicators. The number of suppressed journals in the 2007 to 2014 JCR editions totaled 281. After excluding repeating journals, the number totaled 177.
The results of the study reveal that:
(1)The U.S.A had the highest numbers of suppressed journals, the number was 40. Pakistan had the highest proportion of suppressed journals, the proportion was 4.22%. Commercial scientific publishers are the main publisher of suppressed journals (51.26%). The subject area of Engineering contained the most suppressed journals, the number of suppressed journals was 36. Most of the suppressed journals required two consecutive years or one year to change their abnormal citation patterns, the number of suppressed journals was 161. Only one suppressed journal provided the statement of suppression.
(2)During the period of suppression, most of the suppressed journals had IF values between 0.2 and 0.6. Most of the suppressed journals had SJR values between 0.2 and 0.5. Most of the suppressed journals had self-citation rate between 50% and 60% in WoS. Most of the suppressed journals had self-citation rate between 40% and 50% in Scopus. No matter containing the self-cited data or not, the highest difference of IF values was 13 times.
(3)The first factor of suppressed journals are journal self-citation, including the journal self-citation rate is too high or too low, journal editors cite a large number of references in editorial article, the author self-citations lead to journal self-citation rate is too high. The second factor of suppressed journals are citation stacking, including the relationships of the journal editors and editorial board members may have facilitated the citation stacking, the citation stacking of heterogeneous subject areas, the citation stacking of publishers, the citation stacking of authors. The third factor of suppressed journals are coercive citation.
The suggestions for improvement based on the findings of this study are as follows:
(1)The journal publishers should promote the understanding of suppressed journals, and provide relevant publication policy.
(2)The journal editors should remind the editorial board members, reviewers, authors on the suppressed journal issues, and shouldn’t manipulate or distort the citation behavior.
(3)The authors should strengthen the understanding of suppressed journals, and pay attention to academic ethics and integrity.
(4)The national science and technology policy makers should provide suppressed journal list on their website, and improve relevant academic policy.
(5)The academic library should provide suppressed journal issues or list on their website, and promote the topic of academic ethics and integrity in library instructions.
