It’s not uncommon for us to hear from overworked journal editors that they are faced with a deluge of allegations about a particular author’s papers. And while we think it’s the responsibility of said editors to make sure their publications are as transparent as possible, we’re also sympathetic to the demands that investigations can take.
The Free University of Amsterdam found Peter Nijkamp, one of the nation’s leading economists who has lost several papers for self-plagiarism, has been found guilty of “questionable research practices,” according to the newly released results of an investigation.
Nijkamp has published a strongly worded criticism of the report (at least according to Google Translate, since his writing is in Dutch).
According to independent student publication Ad Valvas, the commission, led by Jaap Zwemmer, a professor emeritus at the University of Amsterdam, found Nijkamp was guilty of “questionable research practices.” University rector Frank van der Duyn Schouten, on the other hand, said in an official statement that there was “insufficient basis” to claim questionable research practices for each article.
The Journal of the American Chemical Society (JACS) has retracted three articles that had earned expressions of concern by chemistry researchers who were under investigation at the University of Texas, Austin.
The newly retracted articles have each been cited more than 50 times, according to Thomson Scientific’s Web of Knowledge.
The three papers are: Read the rest of this entry »
Drug researchers in India have lost their 2013 paper in ACS Medicinal Chemistry Letters because the first author fabricated findings.
The article, by a group from the Maharaja Sayajirao University of Baroda, Vadodara, in Gujarat, was attempting to synthesize and screen novel clot-busting drugs; one compound exhibited the same activity as aspirin or warfarin, but without increasing bleeding time.
Sadly, it appears as if this potential medical advance was not to be. Here’s the retraction notice for “Novel 2-Aminobenzamides as Potential Orally Active Antithrombotic Agents”: Read the rest of this entry »
The authors of a 2011 Science paper that proposed a new way to direct chemical bonds have withdrawn the paper after concerns about the data prompted an investigation and Editorial Expression of Concern last year from the journal. The retraction is the second for the group, which has also had seven other expressions of concern.
After a reader emailed the editors to raise suspicions about the data, corresponding author Christopher W. Bielawski, then based at the University of Texas at Austin, led an investigation of all the figures. It found substantial problems: “In over 50% of the figure parts, the authors deemed the data unreliable due to uncertainty regarding the origin of data or the manner in which the data were processed,” according to the retraction notice.
UT Austin concluded that there had been misconduct, but did not elaborate.
The paper, “Preference for immediate reinforcement over delayed reinforcement: relation between delay discounting and health behavior,” was written by Shane Melanko and Kevin Larkin. It examined whether people who place less importance on the future were also less likely to adopt healthy behaviors, which come with delayed benefits. Melanko, then a doctoral candidate under Larkin, was evidently at one time a psychology student of some promise.
Lawyers one, scientists nil.
Danish judges have overruled scientists in that nation, concluding that a panel of experts erred in finding that physiologist Bente Klarlund Pedersen, of the University of Copenhagen, was guilty of misconduct.
Last September, Pedersen announced that she would fight the ruling of the Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU), which had said she had committed misconduct in four of 12 articles it had examined.
As we reported then, Pedersen’s case is tied to that of another Copenhagen scientist, Milena Penkowa, with whom she had collaborated and who also has been found guilty of scientific misdeeds. (The new ruling does not address Penkowa.) Read the rest of this entry »
Bruce Murdoch, a neuroscientist formerly of the University of Queensland, will appear in court next week to face fraud charges stemming from an investigation that has already led to three retractions, several corrections, and similar charges for one of his colleagues.
The journal Chemical Science has issued an expression of concern over a 2012 article by a pair of Texas researchers whose “unclick reaction” work has been under scrutiny by their institution.
The article, “Homonuclear bond activation using a stable N,N-diamidocarbene,” was written by Kelly M. Wiggins and Christopher W. Bielawski, of UT Austin. It’s the second EoC that we know of for a paper by Wiggins and Bielawski. We covered a previous one, from Science, that appeared in June.
A one-time media favorite is being accused of serious misconduct in three cases where he inserted artificial windpipes into patients and treated them with stem cells. Two of the patients have died; one survives, but needs her airway cleaned every four hours by hospital staff to keep her alive.
A little over two years ago, thoracic surgeon Paolo Macchiarini soared to the top and then sunk to the bottom within days. First, his work implanting artificial tracheas hit the front page of the New York Times. Days later he was placed on house arrest for accusations of fraud and extortion.
We wrote about him a month later, when a paper of his was retracted for plagiarism.
