Troubled article ranking business schools earns expression of concern

jpimAn article that ranked University of Missouri-Kansas City number one in an area of business school training is set to receive an expression of concern. The move follows months of questions over the ranking’s legitimacy, following revelations such as a relationship between the authors and both the school and its top ranked researcher in the field.

In 2011, the business world got a bit of a surprise: In the field of innovation management, the study of how entrepreneurs convert good ideas into profit, the number one school – according to an article in the Journal of Product Innovation Management — was UMKC. Not Harvard, not Stanford, not any other institution that normally tops these types of rankings. UMKC’s Henry W. Bloch School of Management was also home to the number one researcher in that field, Michael Song.

The school, of course, was elated, immediately issuing a press release titled “UMKC Ranked No. 1 in the World.”

But after publication, a UMKC professor raised concerns about the paper’s methodology. An investigation by the Kansas City Star uncovered some issues:

Sticky situation: Paper using honey for healing pulled over data issues

A paper on dressing wounds with honey has been retracted after the journal realized that an outlier patient was throwing off the data analysis.

Honey has been used for millennia as an antimicrobial wound dressing. Doctors can even buy sterile preparations of the sweetener. But the evidence that honey is better than other wound dressings is still inconclusive.

According to the retracted paper, published in International Wound Journal in 2008, Manuka honey has an acidic pH which helps reduce the alkaline environment of chronic woulds. Indeed, the authors found that Manuka honey dressings lowered wound pH and reduced wound size.

Sadly, the paper was pulled in 2014, after someone realized one patient had a particularly large wound that was throwing off statistics. The injury was 61 cm^2 at the beginning of the study, while the others ranged from .9 to 22 cm^2. After removing that patient from the analysis, the results no longer held up.

So you want to be a whistleblower? A lawyer explains the process

We are pleased to present the first in a series of articles by John R. Thomas, Jr., a lawyer at Gentry Locke [Editor’s note, 3/26/19: He has since moved to Haley, Hafemann, Magee and Thomas] who represents whistleblowers in a variety of False Claims Act cases. He writes about how whistleblowers can do the right thing and protect themselves in the process.

As readers of Retraction Watch are well aware, scientific misconduct is a problem for a number of reasons. Science builds upon itself; unfounded scientific results lead to wasted research efforts, ineffective medical therapies, and faulty public policy conclusions. Even one fraudulent paper can have profound effects, such as fueling an anti-vaccine movement.

Research misconduct also erodes public trust in science and endangers ongoing public funding of scientific research. Following the recent discovery of fabricated AIDS research at Iowa State University, Senator Grassley addressed the issue before the U.S. Senate:

Castle made of sand: Self-plagiarism washes away paper on dune particles

sedgeolA group of geologists in China have lost their paper on the aerodynamics of sand particles because the article was mashed together from previous publications.

The article, “The influence of sand diameter and wind velocity on sand particle lift-off and incident angles in the windblown sand flux,” appeared in the May 2013 issue of Sedimentary Geology. It was written by a team from the Key Laboratory of Mechanics on Western Disaster and Environment at Lanzhou University.

Here’s the notice: Continue reading Castle made of sand: Self-plagiarism washes away paper on dune particles

Cell biologists in South Korea retract two papers

jbcA group of researchers at two universities in South Korea have retracted two cell biology papers featuring retinoic acid.

The most recent retraction appears in the Journal of Biological Chemistry. Although, in typical JBC fashion, the reason for it is anyone’s guess.

Here’s the unhelpful notice for “ASXL1 represses retinoic acid receptor-mediated transcription through associating with HP1 and LSD1:” Continue reading Cell biologists in South Korea retract two papers

Warning: plagiarism may be hazardous to your safety paper

12 Process Safety and Environmental Protection (once)A paper on making emergency evacuations more efficient at facilities that handle hazardous materials has been retracted for plagiarism.

According to the Process Safety and Environmental Protection retraction notice, the 2013 paper, by a group at Tsinghua University in Beijing, plagiarized part of a 2007 article by Greek researchers called “Modeling emergency evacuation for major hazard industrial sites.” (The 2007 article has been cited 46 times, according to Google Scholar.)

Here’s the notice for “Emergency Response Plans Optimization for Unexpected Environmental Pollution Incidents using an Open Space Emergency Evacuation Model” (paywalled): Continue reading Warning: plagiarism may be hazardous to your safety paper

Manufacturing paper assembled “almost entirely” from someone else’s 1999 thesis

saeijmmThe SAE International Journal of Materials and Manufacturing has retracted a paper after realizing the authors ripped off a 1999 PhD thesis.

According to the notice, the 2014 paper — about the best ways to set up manufacturing cells in the automobile industry — “is almost entirely taken” from a Durham University, UK student’s PhD thesis. The thesis, “Computer-aided design of cellular manufacturing layout,” was written by Yue Wu. We were unable to track him down after he left the University of Exeter‘s Manufacturing Enterprise Center.

Here’s the notice for “Reengineering the Layout: A CMS Methodological Approach”: Continue reading Manufacturing paper assembled “almost entirely” from someone else’s 1999 thesis

“Irreconcilable difference of opinion” divides math preprint

arxivA fight over a paper posted on preprint server arXiv.org has divided two mathematicians.

The authors initially posted the paper, which looks at the mathematical properties of spheres, in 2013. And that’s when the trouble started.

Apparently, after submitting the paper to a journal and receiving reviewer feedback, co-authors Fabio Tal at the University of São Paulo and Ferry Kwakkel, who got a PhD at the University of Warwick, began to fight over the content of the paper, causing Kwakkel to post his own version, and Tal to withdraw the previous one. “I believe we are severely at odds now,” Tal told Retraction Watch.

In February 2015, Kwakkel, posted a second paper on arXiv.org that he said is his “version” of the 2013 paper, with which it has “substantial text overlap.” Tal requested that the first paper be withdrawn; the note that now appears on “Homogeneous transformation groups of the sphere” cites an “irreconcilable difference of opinion”:

Second cell bio retraction from UPitt investigation of tweaked images

Journal of Cellular Physiology: Volume 229, Number 10, October 2Two researchers, Tong Wu and Chang Han, have lost a second paper as the result of a University of Pittsburgh investigation into image manipulations.

The first retraction, in Journal of Cellular Biochemistry, went live in February. The researchers, currently based at Tulane University, were originally tapped by pseudonymous tipster Juuichi Jigen, who created a website in 2012 to chronicle the allegations.

The blog lists six papers by the pair with supposedly questionable figures. According to Jigen, this latest retraction, in the Journal of Cellular Physiology, contains a figure (2A) that appears to reuse data from another paper, and another figure (3) where the data appear to be manipulated.

Bielawski and Wiggins up retraction count to five with three in JACS

Journal of the American Chemical SocietyThe 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.

Kelly Wiggins and Christopher Bielawski have already received two other retractions and several EoCs.

The newly retracted articles have each been cited more than 50 times, according to Thomson Scientific’s Web of Knowledge.

The three papers are: Continue reading Bielawski and Wiggins up retraction count to five with three in JACS
