In this editorial, I specifically share the journal’s achievements since August 2018 in obtaining Scopus’s CiteScore and for being included in Web of Science’s Social Sciences Citation Index (SSCI), which reflect the journal’s continued growth with on-going strong support from researchers and readers internationally.
