This depends on the particular institutions that are demanding the preparation of the document.
For example, scientific articles, which are given their degree of name and credibility in terms of publication, medium and quality of the same. Academic environments thrive on such publications. Thus, “The scientific article must be organized following the requirements of the publication. The classic structure of the article is: Introduction, materials and methods, results and conclusions. The parts of a scientific article are: Title, author, summary, introduction, materials and methods, results, discussion, conclusion, acknowledgments and bibliographic references. ”(P. 40)
To obtain all this content, it is expected that prior research will be carried out, which will provide possibilities and thoughts around the topic you want to work on. The APA standards audit and filter knowledge as citations and references. Even so, it is important that when inquiring about a topic, an exhaustive investigation is carried out around it, this includes wondering if the topic on which you are going to write was presented by someone else. That is, there are other approaches or approaches to the subject that is going to be exhibited. The foregoing must be evident in the writing of the document, since it denotes the research carried out by the author and also the state of the art of the subject for which it is being investigated.
According to the APA standards, it is unethical to list a problem and not investigate beforehand if it has been developed by another author. Especially in those documents whose demand for innovation or original contribution makes the subject to choose more difficult to find due to the characteristics or requirement demanded by the academic entity.
Therefore, the APA standards require a degree of self-authorship and creativity, supported by relevant citations. A text must have a great innovative content that indicates the skill of the author but also his ethics at the time of writing. Texts that only repeat what is said by other texts are of no use for the evolution of the academic environment, the idea of the knowledge society is that it is unfinished and that new and fresh ideas always arrive for the transcendence of knowledge as utility for the world . The APA standards guarantee, through their guidelines, that knowledge is evaluated even before it is written.
In the case of essays, for example, we note the ability to write prose, where the subjective vision of the author is more important and also his position on any given topic.
