Chemometrics and Intelligent Laboratory Systems, an Elsevier publication, has retracted a 2014 paper by researchers in China and the United Kingdom for data misuse and authorship issues.
The article, “Optimization of fluidized bed spray granulation process based on a multiphase hybrid model,” was purportedly written by Dapeng Niu, of the College of Information Science and Engineering at Northeastern University, in Shenyang, China, Ming Li, of De Montfort University, in Leicester, England, and Fuli Wang, a vice-president at Northeastern.
But Niu apparently didn’t perform any experiments, lifted the data from other sources, and published the paper without his co-authors’ okay.
The abstract, about electric impulses in the brain of comatose patients, originally appeared as a poster at the June 2014 joint meeting of multiple Swiss neuroscience societies. It was submitted by first author Alexandre Simonin, who lists his affiliation as the University Hospital of Lausanne, a Swiss hospital.
The meeting proceedings ran in the October issue of Clinical Neurophysiology. Besides the issues of authorship and errors, the notice also says the abstract “potentially conflicts with another publication,” suggesting the data might have already appeared in a paper.
According to the notice, the senior author told the journal that the data came from the lab Li used to work in at the University of Rome Tor Vergata, but the P.I. in Italy didn’t know about the paper.
An environmental journal has retracted a paper on a technology that helps degrade explosives released into soil, because the first author never got the permission of his “co-authors” — oh, and used data that were “illegally obtained,” according to one of the slighted co-authors.
According to the EPA, more than 30 sites around the country are contaminated by decommissioned explosives, including weapons plants and army depots. A major source of the pollution was workers washing out old bombs into “evaporation lagoons” and then burning the resulting sludge.
The site used for the retracted paper was Ravenna Army Ammunition Plant, a decommissioned weapons factory that stored explosive waste in unlined landfills. According to the EPA, “open burning was also a common practice.”
The problems with the paper in Water, Air & Soil Pollution were uncovered after the head of the company, University of Georgia (UGA) professor Valentine Nzengung, found the paper on ResearchGate. He discovered that first author Chunhui Luo had used (now out-of-date) data without permission, and added Nzengung’s name to the paper without his knowledge. The other author is another UGA professor, Walter O’Niell, who told us he was also not informed about the paper.
Nzengung gave us further details via email: Read the rest of this entry »
The paper, “GREB1 Functions as a Growth Promoter and Is Modulated by IL6/STAT3 in Breast Cancer,” came from a team composed of researchers at the Morehouse School of Medicine, Xavier University of Louisiana and the University of Miami School of Medicine. It purported to find that: Read the rest of this entry »
A group of researchers in Singapore has lost two 2013 articles in BMJ Supportive & Palliative Care for problems with their data.
One of the articles was titled “Patients with Dysphagia: Encounters in Taking Medication;” the other, “Issues Associated with Delirium Severity Among Older Patients.” In both cases, the first and second authors were Rajaram S and Chua HC, of Khoo Teck Puat Hospital.
In September, Bruce Murdoch and Caroline Barwood had a paper in the European Journal of Neurology retracted. Earlier this month, the same happened to a paper in Aphasiology.
The retraction announced by the university today is for a 2013 paper in the International Journal of Speech-Language Pathology.
The Journal of Biological Chemistry has an illuminating retraction notice — we’re happy to be able to say — about a 2001 article from a group of researchers at the National University of Singapore.
The paper, “Intracellular acidification triggered by mitochondrial-derived hydrogen peroxide is an effector mechanism for drug-induced apoptosis in tumor cells,” was written by Jayshree L. Hirpara, Marie-Véronique Clément and Shazib Pervaiz.
A neurosurgeon in the UK has lost his 2013 paper on spinal surgery in the British Journal of Neurosurgery for doing what appears to have been an end-run around the folks that did the work.
The article, “The management of spinal dural fistulas: a 13-year retrospective analysis,” was written by Denosshan Sri, of Addenbrooke’s Hospital, in Cambridge.
Here’s the abstract:
The article, “Health of Home-Based Sex Workers and their Children in Rural Andhra Pradesh, India,” appeared in Asian Population Studies and was written by Monique M. Hennink and Solveig A. Cunningham, both of the Rollins School of Public Health at Emory University in Atlanta.
