All submissions are subject to peer review and editorial control of length and style.
Indicate clearly whether an article is to be considered for publication as a research article or as a review article. Research articles describe important analytical, experimental, or empirical results which add to our knowledge in one or more of the many problem areas of this subject. Review articles, on the other hand, are intended to present considered and objective assessments of a technology or area of practice. They may be based on analytical or experimental models, but if not, they should offer substantive evidence to support the main thesis. As in the case of research articles, review articles must clearly present the implications for future practice.
