Primary Articles, Review Articles, and the Scientific Peer‑Review Process
When researchers make a written report on data they have collected, that report or manuscript is a primary source of information on the topic that was reached. Before primary source reports can be accredited and published the report goes through screening and then on to a peer review process. The screening is done by the editor where they proofread the report for grammar, readability, and substance of the information therein. The next step is the peer review. This is the main quality control process where other scholars in the respective field review the report and assess its importance to the respective field. The multiple step peer review system consists of written dialog between the editor and the reviewers that require several revisions to the original report. When the process is concluded the report is accepted only then is it published as a primary source article.
Another accepted research source is a review article. Unlike a primary source article, a review article does not introduce new material done by the reviewer. Instead, it is a compilation of summaries, critiques, and comparison of existing primary sources on a specific topic. This type of review is done to identify patterns, gaps in knowledge, disagreements, and agreements on the subject matter. Then all the information or data is compiled and organized. The layout of review articles starts with an abstract to introduce the topic. That is followed by paragraphs of the organized data and questions raised. Then there is a conclusion that highlights the current state of the knowledge in the field and suggests directions for future research in attempts, to fill those knowledge gaps. It is concluded with an extensive reference list.
Similarly, a process that involves quality control of information before publication is the scientific peer review process. Just as with a primary source, and review articles, the report is reviewed by experts in the field. The major difference is the structure of the data presented and the acceptance process. The manuscript / report is submitted to the editor for its initial screening, at his stage manuscripts can be rejected. If the manuscript is not rejected it is sent to reviewers. This is the step where the expert reviewer reviews the data. Their focus is on evaluating the clarity of he over all work. Questions like did the researcher take an original approach, how did they run their experiments and were their experiments designed to produce unbiased information and is there statistical analysis of the data and finally will all of this contribute to the field? The third and last step of quality of data reviewing is the peer review evaluation. The peers who are also experts in the field and have successfully completed this process themselves do another review of the manuscript. This final review determines whether the scientific research methods were followed thoroughly, does the data support the conclusion, is the data clearly stated and will the information contribute meaningfully to the field. Step four is where the editor considers all the reviewers’ comments and make necessary revisions to the manuscript. The fifth and last step is acceptance and publication. when all the reviews and revisions are completed to satisfaction the manuscript is accepted and is published.
