Science flags immune-boosting paper under investigation

F1.mediumScience magazine has issued an expression of concern for a paper on the discovery of a new immune-boosting protein. The paper’s findings, which received some press coverage when they came out last spring, are now under investigation by Imperial College London.

The expression of concern follows a correction noting a Western blot mix-up. Science Editor in Chief Marcia McNutt told us last month that the mistake resulted from “carelessness” on the part of the authors. But now, an investigation at Imperial College London — where Philip Ashton-Rickardt led the research — is formally looking into the findings.

That investigation is ongoing, according to the expression of concern (signed by McNutt):

PLOS ONE issues editor’s note over controversial chronic fatigue syndrome research

After a request for the original data was denied, PLOS ONE editors have flagged a 2012 sub analysis of a controversial clinical trial on chronic fatigue syndrome with an editor’s note.

The editor’s note — which reads like an Expression of Concern — reiterates the journal’s policy that authors make data and materials available upon request, and notes that staff are following up on “concerns” raised about the study.

There have been numerous requests for data from the “PACE” trial, as the clinical trial is known, which the authors say they have refused in order to protect patient confidentiality. On November 13, James Coyne, a psychologist at the University Medical Center, Groningen, submitted a request for the data from the PLOS ONE paper to King’s College London, where some of the authors were based. According to Coyne’s WordPress blog (he also has a blog hosted by PLOS), the journal asked him to let them know if he “had any difficulties obtaining the data.” He did — KCL denied the request last Friday (the whole letter is worth reading):

The university considers that there is a lack of value or serious purpose to your request. The university also considers that there is improper motive behind the request. The university considers that this request has caused and could further cause harassment and distress to staff.

Last author Peter White at Queen Mary University of London, UK, told us the journal had not asked them to release the data, but he would work with PLOS to address any questions:

We understand PLOS One are following up concerns expressed about the article, according to their internal processes. We will be happy to work with them to address any queries they might have regarding the research.

Here’s the editor’s note for “Adaptive Pacing, Cognitive Behaviour Therapy, Graded Exercise, and Specialist Medical Care for Chronic Fatigue Syndrome: A Cost-Effectiveness Analysis,” in full:

Paper claiming extra CO2 doesn’t always lower plant nutrients pulled for errors

11Authors have retracted a large meta-analysis claiming that rising levels of carbon dioxide don’t always reduce nutrients in plants.

After commenters on PubPeer raised concerns, the authors say they found several unintentional errors in their data that could “significantly change conclusions” of the paper in Plant Ecology, according to the retraction note.

The paper found that the impact of rising CO2 depends on many factors — in some cases, extra amounts of this greenhouse gas could actually increase plant nutrients. Trouble is, some of the papers that cited the now-retracted article came to the opposite conclusion: Increased carbon dioxide levels do decrease plant nutrients.

The retraction note for “CO2 effects on plant nutrient concentration depend on plant functional group and available nitrogen: a meta-analysis” explains some of the specifics of the errors, and says that there was “no evidence of bias:”

Management researcher with 7 retractions issues “clarifications” to 2013 paper

The authors of a paper on supportive supervisors just want readers to “better understand the reported findings,” and so have issued multiple “clarifications” in a corrigendum note.

Some of the issues addressed in the note have been raised on PubPeer.

The paper’s author list includes one Fred Walumbwa, formerly an Arizona State University management researcher, some of whose work has succumbed to scrutiny in the the past two years. His current list: seven retractions, a megacorrection, an expression of concern, and now this.

Unraveling the relationship between family-supportive supervisor and employee performance,” published in Group & Organization Management, has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Study claiming dramatically higher rates of male military sexual trauma is retracted

psychological servicesA study that found a 15-fold increase in the rate of sexual trauma among men in the U.S. military — and sparked suggestions of “an epidemic of male-on-male sex crimes” in the military among conservative media outlets — has been retracted because of a flaw in the analysis.

The study, published just last week, appeared in Psychological Services, an American Psychological Association (APA) journal. In an announcement Sunday titled “American Psychological Association Retracts Article Positing Excessively High Rates of Sexual Trauma Among Military Men,” the APA said that “Scholars raised valid concerns regarding the design and statistical analysis which compromise the findings.” Here’s the text: Continue reading Study claiming dramatically higher rates of male military sexual trauma is retracted

Journal reviewing papers by researcher who sexually assaulted disabled author

Screen Shot 2015-11-03 at 12.10.00 PMA disability journal is “paying significant attention” to papers authored by Anna Stubblefield, a former Rutgers researcher recently convicted of sexually assaulting a disabled man who participated in her research.

Stubblefield was convicted of sexually assaulting “DJ,” a man in his thirties with cerebral palsy who was “declared by the state to have the mental capacity of a toddler,” according to a lengthy piece in the New York Times. Stubblefield and DJ published papers in Disability Studies Quarterly; in one, Stubblefield describes a controversial technique which she claimed helped DJ communicate. But when she eventually used the technique to say DJ was in love with her, his family took her to court, and she was convicted of aggravated sexual assault.

Here is the note from Disability Studies Quarterly, which was published this morningContinue reading Journal reviewing papers by researcher who sexually assaulted disabled author

Cochrane withdraws criticized alcohol misuse report for “major errors”

Cochrane_LogoThe Cochrane Library has withdrawn a criticized 2014 meta-analysis about a technique to help young people avoid alcohol abuse, because of “major errors.” 

The review found that motivational interviewing, a form of counseling to help people change behaviors, showed some effects but had “no substantive, meaningful benefits” in preventing alcohol abuse among people 25 and younger. However, other researchers in the field, including some whose studies were included in the analysis, soon raised concerns about the review’s methods and data calculation, and the authors withdrew it. 

Here’s the brief notice for “Motivational interviewing for alcohol misuse in young adults:”

BMC investigating allegedly copied paper

logoBioMed Central is investigating a recent paper about a potential biomarker for liver cancer, which shows signs it was written using another article as a template.

According to Jeffrey Beall, who exposed the similarities between the two papers on his blog Scholarly Open Access yesterday, the paper in question is “obviously bogus,” and appears to have relied on the “template plagiarism” technique of creating a new article by modifying a previous paper’s text and data.

A spokesperson for BioMed Central, which published the allegedly “junk” paper, as Beall calls it, told us they are looking into the allegations: Continue reading BMC investigating allegedly copied paper

Authors “did not have permission” to use pesticide data

10661An environmental journal is retracting an article about the risks of pesticides to groundwater after determining it contained data that “the authors did not have permission (implicit or explicit) to publish.”

According to the retraction note in Environmental Monitoring and Assessment, the paper said the data came from a non-author’s PhD thesis, but it’s not there. Those mysterious data were used to validate a model for pesticide exposures, described in an excerpt from the abstractContinue reading Authors “did not have permission” to use pesticide data

Cochrane withdraws review on zinc for colds for data concerns

Cochrane_LogoThe Cochrane Library has withdrawn a 2013 systematic review on zinc’s ability to fight the common cold.

Cochrane often marks reviews “withdrawn” once new evidence emerges that renders them out of date — but in this case, the review was flagged while the editors investigate issues “regarding the calculation and analysis of data.”

Here’s the notice.
