Fred Walumbwa, a management researcher with eight seven retractions, has received three expressions of concern from two journals after he failed to provide raw data following an investigation into potential errors.
In the past, Walumbwa has said he only keeps data until his papers are published, but a lack of raw data has become a common theme in his notices, which now also include four corrections, and one other EOC (making a new total of four). There are no standard rules about how long to store raw data, but one journal that issued two of the new EOCs has since updated its submission policy to require that authors keep data for at least five years.
Here at Retraction Watch, we have a lot of fun exploring all the different kinds of science that cross our paths.
Some, though, we’re just not qualified to understand, like this retracted paper in the Journal of Management Studies, which according to the abstract “demonstrates that the persistence of brokerage positions decreases broker performance.”
What is clear is the retraction: the author already published the conclusion in a Japanese management journal in 2011.
