This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor. Post-publication, the editor discovered suspicious citation patterns. Blocks of references were cited out of context, and some of the references were far outside of the subject areas. Upon inspection of the submission record, it was discovered that many references were added to the final approved versions during the proofreading stage. In addition, an author was added during revision without the approval of the editor, which is a violation of the journal policy on change of authorship. The editor decided that the findings of the articles could not be relied upon, and the articles should be retracted. The corresponding author agreed to the retractions.
