Concerns attached to three more papers by retraction-laden management researcher

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.

Walumbwa currently works at Florida International University. When concerns about the statistics were raised about five of his papers in Personnel Psychology, the journal conducted an investigation that led to flagging two of those articles, the expression of concern explains:

Management researcher with 7 retractions issues “clarifications” to 2013 paper

The authors of a paper on supportive supervisors just want readers to “better understand the reported findings,” and so have issued multiple “clarifications” in a corrigendum note.

Some of the issues addressed in the note have been raised on PubPeer.

The paper’s author list includes one Fred Walumbwa, formerly an Arizona State University management researcher, some of whose work has succumbed to scrutiny in the the past two years. His current list: seven retractions, a megacorrection, an expression of concern, and now this.

“Unraveling the relationship between family-supportive supervisor and employee performance,” published in Group & Organization Management, has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Here’s the note in full:

Retraction-plagued management researcher hit with expression of concern

OrgBehav_ak13The editor-in-chief of Organizational Behavior and Human Decision Processes has issued an Expression of Concern about a 2011 paper that explores the link between ethical leadership and employee performance.

The paper, “Linking ethical leadership to employee performance: The roles of leader–member exchange, self-efficacy, and organizational identification,” is one of seven that were flagged in a report by Arizona State University (ASU) that investigated the corresponding author, Frederick Walumbwa, for possible research misconduct, as we noted in November.

“The fit statistics reported in the article contain many errors,” the notice says. It goes on to say that “it is difficult to understand the implications of these errors unless the raw data is made available” — but that the authors were not able to provide it. Here’s the full text of the expression of concern: Continue reading Retraction-plagued management researcher hit with expression of concern

The Leadership Quarterly has retracted a trio of papers by Frederick Walumbwa, an “ethical leadership” guru at Florida International University, whose work has come under scrutiny for flawed methodology. And another journal  has pulled one of his articles for similar reasons. That brings his count – as far as we can tell — to seven retractions and a mega-correction.

Meanwhile, Arizona State University, Walumbwa’s former employer, has found

that the preponderance of evidence does not support the charge of research misconduct by Dr. Walumbwa…

but that he engaged in “poor research practice.”

The bottom line, according to the Leadership Quarterly, which first announced problems with the articles in February:

Fred Walumbwa, the leadership researcher at Florida International University who has retracted six papers for what appear to be problematic data, now has an impressive mega-correction in the form of an “addendum.”

The paper, “Relationships between Authentic Leadership, Moral Courage, and Ethical and Pro-Social Behaviors,” was published in Business Ethics Quarterly in October 2011, by Walumbwa and two colleagues, Sean Hannah and Bruce Avolio.

Here’s the abstract for the paper, which has been cited 18 times, according to Thomson Scientific’s Web of Knowledge:

Florida leadership researcher Walumbwa notches sixth retraction

jorgbehavIn February we reported on the case of Fred Walumbwa, a leadership scholar at Florida International University who was poised to lose five papers in the Leadership Quarterly for reasons not entirely clear but which appeared to involve problems with the data.

Now we see a sixth retraction for Walumbwa, this one in the Journal of Organizational Behavior. The article, titled (ironically enough), “Authentically leading groups: The mediating role of collective psychological capital and trust,” had appeared in September 2009. Per the abstract:

Retraction Watch has learned that The Leadership Quarterly, a management journal published by Elsevier, plans to retract five papers by a Florida researcher poised to “rock” the field — but probably not quite in the way a press release intended — whose findings in the articles were questioned by readers.

The scholar, Fred O. Walumbwa, had a “stellar history of excellence and achievement,” according to this August 2013 press release from Florida International University announcing his move from Arizona State: Continue reading Leadership journal to retract five papers from FIU scholar
