This isn't the world's best sentence, but it's not wrong, and it's not a Valley Girl verbal tic. Of course, there are appropriate uses, especially when "like" is being used as a preposition: Martin was so tired that he looked like a zombie.
I edit them professionally and see it used frequently. Rather, the Introduction, Methods, Results, and Conclusion sections should speak for themselves.
In particular, a "like" phrase can function as an adverb; "he sings like Caruso" is correct.
The difference between "like" and "as" (when they express similarity --- both words have several other meanings) is that "like" is a preposition and "as" is a conjunction.
To make sure that the authenticity is addressed, it is significant to avoid any form of plagiarism and learn the proper citation standards.
Lastly, considering the coherence, one should make sure that a research paper has a clear structure, strongly organized points, and consists of such parts as abstract, introduction, body paragraphs, and a well-built conclusion.
In a research paper one should not use the word “you”.
Unless directly asked from the task the paper should not contain a personal statement either.
One of the things she emphasized a lot (if not the most) as being bad is saying the word “you” in an essay/ research paper.
She said that the only spots appropriate to use the word “you” in your paper is when giving your personal statement (usually in an argumentative essay or one that asks for your views on the matter).For example, it would be correct to write "This simplification is like the one in Eq.(2)." EDIT: What I wrote about the example sentences is right, but the reason I gave, now in brackets ... above, is wrong.There exist many definitions of what is a research paper.Generally, any research paper can be defined as a piece of writing that presents a personal interpretation or evaluation of particular arguments and is based on either or inductive or deductive approaches.The keywords of any traditional research paper assignment are credibility, authenticity, and coherence.Contrary to what one may think, writing a research paper is not only copping some information from the external sources and putting them together. As far as credibility is concerned, a person should read particular literature and get acquainted with many credible sources before starting writing the paper. ]]
