Comments on abstract, title, references

The title is informative and relevant. about the problem: The problem statements agreed with the title and seemed to be of educational significance. The problem was not clearly visible to the average reader, and it required several readings to establish why the researchers felt this study needed to be done. About the references: Relevant and Referenced correctly.

Comments on introduction/background

The manuscript is well-written and nicely presented, with a good balance of descriptive text and discourse. Lack of research hypothesis.

Comments on methodology

The sample chosen is not representative, and the general population of the sample is not present. The methods used for data analysis are not well described.

Comments on data and results

The methods used for data analysis are not well described. The findings were well organized, sectioned, and reported objectively. The tables were well organized but, due to the difficulty of the statistical tests employed, would not stand alone to the average reader.

Comments on discussion and conclusions

The discussion of data citation was good and captured the state of the art well, but I would have liked to see some views on a way forward. Have we solved the basic problem and are now just dealing with edge cases? Is the “just-in-time identifier” the way to go? What are the implications?. the conclusions answer the aims of the study.
