Do not include context for the sake of including context: Rather, provide only what will help readers better understand the need and, especially, its importance.
Consider anchoring the context in time, using phrases such as recently, in the past 10 years, or since the early 1990s.
They are more likely to be cited by other scientists if they are helpful rather than cryptic or self-centered.
Scientific papers typically have two audiences: first, the referees, who help the journal editor decide whether a paper is suitable for publication; and second, the journal readers themselves, who may be more or less knowledgeable about the topic addressed in the paper.
Finally, they structure the content in the body in theorem-proof fashion, stating first what readers must remember (for example, as the first sentence of a paragraph) and then presenting evidence to support this statement.
In the Introduction section, state the motivation for the work presented in your paper and prepare readers for the structure of the paper.You may also want to anchor your context in space (either geographically or within a given research field).Convey the need for the work as an opposition between actual and desired situations.Here are three examples of such a combination: An Introduction is usually clearer and more logical when it separates what the authors have done (the task) from what the paper itself attempts or covers (the object of the document).In other words, the task clarifies your contribution as a scientist, whereas the object of the document prepares readers for the structure of the paper, thus allowing focused or selective reading. " Although papers can be organized into sections in many ways, those reporting experimental work typically include Materials and Methods, Results, and Discussion in their body.The traditional Results and Discussion sections are best combined because results make little sense to most readers without interpretation.When reporting and discussing your results, do not force your readers to go through everything you went through in chronological order.You can similarly prepare your readers for an upcoming division into subsections by introducing a global paragraph between the heading of a section and the heading of its first subsection. Mention these things early in your paragraph, ideally in the first sentence.This paragraph can contain any information relating to the section as a whole rather than particular subsections, but it should at least announce the subsections, whether explicitly or implicitly. If you use a standard or usual procedure, mention that upfront, too.One elegant way to express the desired part of the need is to combine it with the task in a single sentence.This sentence expresses first the objective, then the action undertaken to reach this objective, thus creating a strong and elegant connection between need and task.
