Writing a paper?
The best guide that I have found to help you do this is:
Kazdin, A. (1995) Preparing and Evaluating Research Reports.Psychological Assessment .Vol. 7, No. 3, 228-237.
Download it here (Copyable and downloadable PDF):
Especially useful is page 232. Read it.
The most of your time and energy should be spent on the section that brings your novelty - what new findings or theories you bring to your field of research. Then literary review, method, and then introduction and conclusion.
