* be complete (meaning that you motivate what you do, compare yourself with your peers, and provide a background description in such a way that the reader can follow you up until the state at which you provide your new contribution (i.e., the literature survey),
* be written in a way that it can be understood, and fairly to others - such as in the use and conclusions of numerical experiments,
* and of course you need to motivate that the article should exist at all, i.e., you need to explain very well what you do, how you do it, and why.
These are some of the main rules to follow. I venture to suggest that you might not have followed all those rules. Check your manuscript now that you have read this, and try again, and compare the results from your first attempt with the second one. I think you will be pleasantly surprised!
Kumail - I personally don't agree that 'beginning' researchers manuscripts are rarely accepted. If they are - it's probably more because of inexperience or, sometimes, 'trying to hard to impress'. New researchers who work alone are also more likely to face rejection than if they are collaborating with more experienced researchers/authors.
There are many 'tips and tricks' for increasing chances of successful publication for early, mid and later career researchers. The principles are often general across many disciplines as well. The attached chapter on disseminating research findings may assist.
Dean Whitehead It’s true that many young researchers try to do work alone which leads to rejection and ultimately they get tiered of writing. Research should be started under the supervision of seniors. Thanks for answering.
My first two attempts - with my supervisors - both yielded a publication in quite good journals indeed, albeit after two revisions, but that is still the norm today - even for some hot-shots - so why should we be allowed to sail towards the publication harbour without any problem?
I think that the problem is not related to the journal itself but to the process of review, reviewers and the journal editor. The process of selecting a good article is very selective.
Wassim J. ALOULOU yeah i think selection of topic and then article matters a lot. Experienced researchers have more idea in this regard. That's why there acceptance is higher.
