You focus on the findings and conclusions of other researchers and then make a personal conclusion about the topic.It is important to stay neutral and not show your own negative or positive position on the matter.
The types of publications are different in different fields.
For instance, a clinical trial is possible only in the field of medicine, while an empirical study is more common in the field of social sciences.
You should include and cite findings and arguments of different researchers on both sides of the issue, but then favor one side over the other and try to persuade the reader of your side.
Your arguments should not be too emotional though, they still need to be supported with logical facts and statistical data.
Although original research sometimes takes years to complete, it does not mean you cannot have any publications to your credit till the time you complete your research.
There are different types of scholarly literature, some of which require original research (categorized as primary literature) and some that are based on other published work (secondary literature).
Clinical trials also require practical work experience, as well as, high standards of ethics and reliability.
Perspective pieces are scholarly reviews of fundamental concepts or prevalent ideas in a field.
These are detailed studies reporting original research and are classified as primary literature.
They include hypothesis, background study, methods, results, interpretation of findings, and a discussion of possible implications.
