Preparation of Manuscripts
Submission of an article implies that the work described has not been published previously (in any language), and that it isnot under consideration for publication elsewhere. Although the editors and referees make every effort to ensure the validity of published manuscripts, the final responsibility rests with the authors, not with the Journal, its editors, or the publisher.
The author(s) submitting a manuscript to the journal understand that, if the manuscript is accepted for publication, copyright of the article should be assigned exclusively to the Journal. Upon acceptance of an article, authors will be asked to sign a Disclaimer Form <http://www.hkag.org/ajgg/>. If an author intends to reproduce the published article, either in part or in whole, he or she should obtain permission in written form from the Editor.
