Goodmorning everyone
I know that when you use the same dataset to write more articles you run the risk of not being ethically correct, the phenomenon of salami-slicing research. But what if I had a "hybrid" database made up of already published data and new, never published data? In that case, would it be ethically acceptable?
For example, having published data on the quantitative and qualitative production of apples in northern Italy and now using that data to compare it with that of other apples in central and southern Italy and also other fruits (Plums, peaches...) of the same nation to highlight this time the approval rating of supermarket customers. In this case, in the aim of the paper would be obviously different, but the database would have some raw data already published...
I believe that by explaining the situation in the cover letter to the editor, the problem does not arise, but I would be curious to know other opinions on the matter.
Thanks
The data seems to me not the problem. Data may be used several times if there are new ideas how to analyse, or additional data were obtained which may change the results, or errors in previous analyses were detected, etc. The question is whether there are considerable new results worth to be published.
Matteo Francioni , yes it seems you can do that according to the nature of your study.
Thank you all for the comments. Of course, the data I posted is just an example to simplify the matter, apples are not my research interest, at least not yet
Thanks
I don't see a problem of using data in different paper with different purposes. Even is better to publish first the raw data in a journal focused just in publishing data, and then use it and reference it in those papers related or using the data set.
In this case is also possible that someone use your raw data for its own purpose, referencing it.
Best Regards
