So, pot may not be as harmless as a recent study suggested

adb-150

Researchers are correcting a widely covered study that suggested chronic use of pot might not put users at risk of problems later in life.

It turns out that initial, unexpected finding — covered by Newsweek, The Washington Post, Quartzand (of course) The Stoner’s Cookbook (now known as HERB) wasn’t quite right, and a reanalysis found users had a small uptick in risk for psychosis. The authors have issued a lengthy correction in Psychology of Addictive Behaviors that includes some supplemental analysis, too.

Not surprisingly, the study’s findings engendered some controversy, which prompted the authors to reanalyze their data, collected from 408 males with varying levels of marijuana use, who were followed from their teens into their 30s.

Now, an American Psychological Association press release that accompanied the initial findings in August contains an editors note explaining why those aren’t quite correct:

Wiley published a biology paper in the wrong journal

Screen Shot 2016-01-04 at 2.47.07 PMWiley Periodicals is withdrawing a biochemistry paper after mistakenly publishing it in the wrong journal.

The mistake took a few months to sort out.  Wiley initially published “Protein Kinase C Is Involved in the Induction of ATP-Binding Cassette Transporter A1 Expression by Liver X Receptor/Retinoid X Receptor Agonist in Human Macrophages” online in Journal of Cellular Physiology in May of last year. The article was posted in the correct journal — Journal of Cellular Biochemistry — in July.

At the very end of 2015, the publisher officially withdrew the version it posted in the Journal of Cellular Physiology.

Here’s the withdrawal note (which is paywalled — tsk, tsk):

Here are the 10 — yes, 10 — reasons PLOS ONE retracted this paper

Screen Shot 2016-01-19 at 10.50.25 AMPLOS One is retracting a paper for overlapping with a Wikipedia page. And for containing material lifted from other sources. And for “language errors.” And for insufficient evidence that authors found the pathogens floating around in hospital air that they claimed to find.

The instances of plagiarism are a “huge problem,” each “enough for retraction on its own,” Jonathan Eisen, a microbiologist at the University of California, Davis, told us. Eisen, who posted several comments to the paper after its publication in October, added that the paper was “simply not technically sound.”

The paper — which even contains a spelling error in its title, “Metagenomic Human Repiratory Air in a Hospital Environment” — describes a gene sequencing method to screen the air in hospitals for pathogens. The retraction note lists 10 concerns with the paper: Continue reading Here are the 10 — yes, 10 — reasons PLOS ONE retracted this paper

Paper on pine tree genetics chopped for duplication

naslovna_vol6_no2A paper on genetic variability in Austrian pine trees apparently didn’t vary enough from other work.

The journal is now retracting the 2012 paper for having significant overlap with another paper published in 2008. Another researcher pointed out the duplication — which was unintentional, according to the note, the result of

an apparent failure in communication between the co-authors on both papers which caused the papers to be overlapped.

The overlapping papers share a first author, Aleksandar Lucic, who works at the Institute of Forestry in Serbia. The other author on both papers is Vasilije Isajev, at the Faculty of Forestry in Belgrade.

Analysis of Genetic Variability of Austrian Pine (Pinus nigra Arnold) in Serbia Using Protein Markers” was published in South-East European Forestry. The journal is not indexed on Thomson Scientific’s Web of Knowledge.

Three expressions of concern added to cancer researcher’s notice list

3.coverQuestions about data and conclusions in papers by a cancer researcher at the University of Maryland have led to three expressions of concern in the Journal of Biological Chemistry.

The notices follow four retractions — two for image duplications and two for unknown reasons — for Anil K. Jaiswal. The three papers under notice are all on mechanisms that regulate gene expression; PubPeer commenters have raised questions about some of the figures in the papers.

The expression of concern on all three papers reads, in full:

Satellite paper grounded for plagiarizing — from the same journal

1-s2.0-S0094576515X00129-cov150hPlagiarism happens; we see it a lot. But some cases stand out from the crowd.

For instance, we just came across an example where authors plagiarized from a paper in the same journal. Specifically, a 2015 paper on satellite orbits was found to have “extensive overlap” with another paper published in Acta Astronautica four years earlier. The last authors of the papers have connections, too — they used to work together at the Vikram Sarabhai Space Centre in India, and in 2006, they co-authored a paper together.

M. Xavier James Raj is author on the retracted paper. He was a PhD student under R.K. Sharma, author of the paper he borrowed from. Sharma currently works at Karunya University in India.

Here’s the retraction note for “Analytical orbit predictions for low and high eccentricity orbits using uniformly regular KS canonical elements in an oblate atmosphere:”

Robot for stroke patients paper copied 3 pages of equations

A 2014 paper on a robotic system for patients who have had a stroke contains three pages of equations that are not original.

According to the retraction note, “Cascade controller design and stability analysis in FES-aided upper arm stroke rehabilitation robotic system” copied the equations from a paper that other researchers presented at a conference in 2012. The papers both describe a system that delivers a boost of electricity to stroke patients’ arms to help them perform a task.

Here’s the note, from Nonlinear Dynamics:

Communications researcher regrets “severe shortcomings” in three publications

3A communications researcher in Switzerland has made a few errors in his efforts to communicate his research.

Peter J. Schulz, who works at the University of Lugano, has lost a paper which did not “appropriately acknowledge” another paper as its primary source. He has also corrected a paper with “severe shortcomings in the references.” Both papers were published in the journal Argumentation. 

In addition, he is facing allegations that a book chapter contains some unattributed material.

Schultz acknowledged the problems in a statement he emailed to us:

I regret very much the severe shortcomings in the three publications.

Here’s the retraction note for “Comments on ‘Strategic Manoeuvring with the Intention of the Legislator in the Justification of Judicial Decisions’”: Continue reading Communications researcher regrets “severe shortcomings” in three publications

Paper claiming GMO dangers retracted amid allegations of data manipulation

FNS2015012717103119A nutrition journal is retracting a paper about potential dangers of eating food containing genetically modified organisms (GMOs) for duplicating a figure, as news stories from Italy are reporting accusations that the last author falsified some of his research.

In the paper, Federico Infascelli, an animal nutrition researcher at the University of Naples, and his colleagues showed modified genes could wind up in the blood and organs of baby goats whose mothers ate GM soybeans. According to our Google Translate version of an article by Italian newspaper La Repubblicaan investigation suggests that Infascelli has manipulated images to suggest GMOs are harmful. He could face fines and be suspended from the university.

La Repubblica reports that a committee appointed by the rector of the university, Gaetano Manfredi, found errors in Infascelli’s data that suggested he had manipulated the results to show GMOs were harmful.

One paper by Infascelli has been retracted from Food and Nutrition Science, Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean.” The retraction note says the paper was pulled for duplication:

Fast-tracked PNAS papers are cited less often — but gap is shrinking

PNASAn analysis of more than 50,000 papers submitted to Proceedings of the National Academy of Sciences (PNAS) shows that those published using its “contributed track” — in which academy members can fast-track their own papers by coordinating the peer-review process themselves — have been cited less often than regular submissions, but that gap is shrinking.

Although the overall average difference in citations between contributed and regular submissions was 9%, the yearly difference has declined from 13.6% in 2005 to 2.2% in 2014, according to the new study, posted before peer review on the preprint server bioRxiv by Phil Davis, an independent researcher and publishing consultant based in New York.

The contributed track is a long-standing editorial practice of PNAS, which has triggered concerns from some academics that say Continue reading Fast-tracked PNAS papers are cited less often — but gap is shrinking
