How to deal with the editorial decisions:

Accept: Rare for research articles, would question the peer review process
Revision:
Carefully consider reviewer comments
•Approach a revision decision as an opportunity to develop your paper into the best it can be
•Referee’s comments should not be seen as negative criticisms but development points
•Not all changes have to be made but require convincing arguments for changes not made
Remember! Your response may go back to reviewers. You may need to convince them and the editor!
Reject:
There are many reasons for a rejection, some of the common ones are listed here:
        Technical/scientific issues
Remember that journals generally receive more articles than they can publish. Also in this environment of increasing metricisation titles have to be extremely selective in what is accepted.
A rejection does not necessarily mean that your work is insignificant. There is likely to be a publication that will accepted it.
