How to explain the novelty of your research (Part 2)

The first post in this series looked at language that can be used when there is a knowledge gap. This post will focus on language you can use when there is an inconsistency in current knowledge, or a problem.

Here are some examples:

• "However the definition of compost and biowaste stability is a matter of some debate." (MacLeod et al. 2008)
• "The effects of sex steroids on the GH-IGF system reported to date are enigmatic." (Hansen et al. 2013)
• "The use of artificial media and amended soils in ecotoxicity studies remains a subject of debate." (Maderova et al. 2009)

To indicate an inconsistency or problem in current knowledge, these examples all use a word that implies some kind of doubt or controversy. A similar word that would also work well is "conflict", as in: "Reports on X appear to conflict." Because these sentences all summarize the state of the art in their field, they would work well at the beginning of a paragraph full of examples, as Maderova et al. do in their article.

EXERCISES 
Read some studies in your field that were written by researchers working in English-speaking countries. Do they make clear what is unknown? How do they make it clear? With the pattern we have seen today, or with different language?

COMING UP
I am going to take a break from writing during the next two weekends, so my next post will be on January 5th, 2014.
