Data “irregularities” sink paper on water treatment

desal water treatmentDesalination and Water Treatment has retracted a paper it published in January by a pair of Turkish researchers for “irregularities in the methodology and data management.”

The article, “Molecular simulation of Zn2+, Cu2+, Pb2+, and NH4+ ion-exchange in Clinoptilolite,” investigated how well different natural forms of the zeolite Clinoptilolite remove heavy metals from wastewater. It came from the lab of Mehmet Göktuğ Ahunbay, of Istanbul Technical University, accompanied by first author Barış Demir.

BioMed Central retracting 43 papers for fake peer review

bmc logoBioMed Central is retracting 43 papers, following their investigation into 50 papers that raised suspicions of fake peer review, possibly involving third-party companies selling the service.

In November 2014 we wrote about fake peer reviews for Nature; at that point there had been about 110 retractions across several journals. The addition of 16 retractions by Elsevier for the same reason, and today’s 43 from BMC, brings retractions resulting from the phenomenon up to about 170.

BMC has also contacted institutions regarding 60 additional papers that were rejected for publication, but seem to be part of the same kind of scam. Regarding the third-party agents, BMC senior editor of scientific integrity Elizabeth Moylan writes: Continue reading BioMed Central retracting 43 papers for fake peer review

Pain paper scratched for authorship issues

ejacoverA group of pain researchers in Austria has lost their 2014 paper in the European Journal of Anaesthesiology because one of the authors wasn’t, well, one of the authors.

The article, “Intravenous nonopioid analgesic drugs in chronic low back pain patients on chronic opioid treatment: A crossover, randomised, double-blinded, placebo-controlled study,” came from a team at the Medical University Vienna and Evangelical Hospital Vienna.

During the study, the authors tested whether intravenous infusions of nonopioid drugs (such as paracetamol, or Tylenol) helped people with chronic back pain who take opioids regularly. They found that people’s pain levels decreased in the days leading up to treatment, when they were receiving a placebo, but not after the actual infusion. The results likely stem from “expectation-related mechanisms,” they wrote. Continue reading Pain paper scratched for authorship issues

Unkosher reuse of data forces retraction of minced pork paper

foodmicroThe journal Food Microbiology has pulled a 2012 paper on pork processing which, as we reported earlier, contained salami-sliced data.

The article, “Bayesian inference for quantifying Listeria monocytogenes prevalence and concentration in minced pork meat from presence/absence microbiological testing,” came from a group at the Department of Food Science and Technology at the Agricultural University of Athens, in Greece.

Bitter herbs: Parsley paper retracted after authors omit colleague

ljfp20.v018.i06.coverA pair of plant experts at Uludag University, in Turkey, has lost a paper on techniques for drying parsley because they evidently left a key contributor off the manuscript.

The article, “Effect of Vacuum, Microwave, and Convective Drying on Selected Parsley Quality,” was published online in June 2011 by the International Journal of Food Properties.

During the study, the authors subjected parsley (Petroselinum crispum Mill.) to the various drying techniques, then measured how much each degraded the sample.  Ascorbic acid — a particularly “important indicator of quality,” according to the authors — was lowest after convective drying, and highest after using the microwave. “At the end of the study, microwave drying at 750–850 W ensured the shortest drying time and the best overall quality of parsley; thus, it was chosen as the most appropriate technique for parsley drying.”

But as the retraction notice states: Continue reading Bitter herbs: Parsley paper retracted after authors omit colleague

Genetics journal isn’t down with O.P.D. – stealing other people’s data

GMR logoGenetics and Molecular Research, an online-only journal, has retracted two articles about gastric cancer by a group of Iranian researchers who appear to have put their own names on other people’s data.

Both articles were published in 2014. One was titled “Absolute quantification of free tumor cells in the peripheral blood of gastric cancer patients;” the other, “ZNF797 plays an oncogenic role in gastric cancer.” The list of authors on the two papers isn’t identical, but both papers share a few in common, including the same two last authors: F. Ghasemvand and S. Heidari-Keshel.

It turns out, Saeed Heidari-keshel wasn’t down with other people’s data, and alerted the journal to the problem.

Here’s more from the retraction notice for the first article, which was found to be “substantially equal” to another paper: Continue reading Genetics journal isn’t down with O.P.D. – stealing other people’s data

How should journals handle multiple allegations from the same person?

copeIt’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 Committee on Publication Ethics (COPE) offers suggestions for dealing with these issues in a new discussion document. As COPE explains: Continue reading How should journals handle multiple allegations from the same person?

Retraction after education researcher tries to repeat a grade–er, paper

AEHEAn education journal has yanked a 2014 article by a pair of scholars in Asia after discovering one had already published a “substantially similar” article.

The article, “Dynamic nature of washback on individual learners: the role of possible selves” in Assessment & Evaluation in Higher Education, is about how taking a major English test influenced learning in Chinese undergraduate students. Author Ying Zhan is listed at Guangdong University of Foreign Studies, in mainland China; Zhi Hong Wan, at the Hong Kong Institute of Education.

Authors retract PNAS Epstein-Barr virus paper for “anomalous and duplicated” figures

pnas 2515PNAS has retracted a paper on the cancer-causing Epstein-Barr virus just two months after publication, in a notice that fingers a now-former graduate student for manipulating figures.

The paper tries to explain how Epstein-Barr virus blocks the immune system’s attempts to destroy it. According to the notice, the three “nonexperimentalist authors” – identified in the paper as two P.I.’s from University of Texas at Austin and one from the University of California, San Francisco – didn’t know the figures “were not reflective of original Northern blot and immunoblot data.”

That leaves UT Austin PhD student Jennifer Cox under the bus. Her LinkedIn says she pursued a PhD from 2010-2015, though it’s unclear if she’s received a degree. Cox’s name is at the top of P.I. Christopher Sullivan’s list of past lab members, and she’s the only one on the page whose name doesn’t hyperlink to additional information, such as a contact.

The school issued a press release about the study that quoted Cox, which has been removed from the UT site but is still available on Science Daily: Continue reading Authors retract PNAS Epstein-Barr virus paper for “anomalous and duplicated” figures

An end to fake papers? New software to check for SCIgen-created manuscripts

springerSorry, fans of papers by Maggie Simpson and I. P. Freely, your days of chortling may be coming to an end.

Springer, responding to a case last year in which it and IEEE had to eventually retract more than 120 papers created by SCIgen, is making software that detects such manuscripts freely available.
