University president faces allegations of duplication, institution says no misconduct

The president of the Kyoto Institute of Technology (KIT) has corrected two of his papers and is set to correct another amid allegations of duplication – sometimes inelegantly referred to as “self-plagiarism” – despite a university committee clearing him of misconduct.

Employees at the university have accused president Masahiro Yoshimoto of duplication between 11 sets of his published papers – implicating 34 papers in total.

The employees submitted the allegations to the institution last October, backing their claims with an analysis by plagiarism detection software iThenticate. Two of these employees spoke to Retraction Watch on condition of anonymity, fearing a loss of support from their colleagues if they spoke publicly. Their concerns triggered an investigation at KIT, which cleared Yoshimoto of misconduct in January. However, the whistleblowers still believe the papers should be retracted.

Indonesian university dean dismissed, barred from teaching, asked to apologize

Kumba Digdowiseiso has been dismissed from his position as dean of the economics and business faculty at the Universitas Nasional (UNAS) in Jakarta, Indonesia, following an investigation into claims he used the names of other academics without consent on papers with which they were not involved.

Digdowiseiso had already announced his resignation from the university on April 19, a week after Retraction Watch reported several researchers from the Universiti Malaysia Terengganu (UMT) were accusing Digdowiseiso of using their names on papers without permission.

At the time, the university’s official account on X had reposted Digdowiseiso’s response to our report in a now-deleted tweet from April 11. In the tweet, Digdowiseiso wrote that after an internal meeting with UMT, the institution decided the authorship allegations were “a personal issue” and therefore didn’t need “further intervention/action from both universities or even faculties.” Another UNAS tweet from April 14 that is still online does not include this paragraph.

Caught by a reviewer: A plagiarizing deep learning paper lingers

Last May, Devrim Çavuşoğlu, an engineer at Turkish software company OBSS, was looking at feedback from a conference reviewer of a paper he and his colleagues had submitted. One comment stood out to him: The reviewer had noticed a resemblance between Çavuşoğlu’s work and another paper accepted to a different conference on computational linguistics.

When Çavuşoğlu first skimmed through the other paper, he came across some sections containing an uncanny resemblance to his own ideas. “I thought, it’s like I wrote that,” he recalled. “How could it be so similar, did we think about the same thing?”

He checked the accompanying source code and found the authors of the other paper seemed to have directly copied and built upon his own publicly released code without any attribution – a violation of the license connected to the work. “I was shocked, to be honest,” Çavuşoğlu told Retraction Watch.

Lack of permits, ‘selective’ data halt research at Swedish prosthetics research center

In the late afternoon at a conference in Cartagena last year, a team of Swedish researchers presented their work on a technique that uses machine learning to translate the body’s own electric signals used to move a limb. They had tested it on a minor recovering from a stroke.

Documents from an internal investigation shared by Chalmers University have now revealed, however, that this case study was part of a series of regulatory lapses and suspicious research practices at the Centre for Bionics and Pain Research (CBPR) where the clinical research was conducted. The researchers seem to have conducted the study before Max Ortiz-Catalán, the center’s founder and former manager, had secured regulatory approval from the relevant Swedish agency.

Chalmers, the Centre’s home, has now suspended it after also suspecting that its data and research participants seemed “systematically selected” so that treatments appeared effective, and excluded data when treatments caused health problems. The investigation also uncovered the center had no person responsible for compliance, which is a requirement under Swedish law, and that personal data had been handled poorly.

Exclusive: Psychology researcher loses PhD after allegedly using husband in study and making up data

A psychology researcher already under fire for several questionable studies has had her PhD revoked by a university tribunal that found it likely she fabricated data in her thesis.

Ping Dong, who was a doctoral student at the University of Toronto from 2012 to 2017, had already earned retractions for two papers based on her thesis before the tribunal’s decision to cancel her degree and give the thesis a failing grade. A summary of the case the school has made available online reveals those retractions, which we’ve previously reported on, arose from more serious misconduct than previously publicized and were also subject to an institutional investigation.

Dong’s research concerned how moral violations and unethical behavior, such as tax evasion or adultery, influence consumer choices.. According to the university’s report, her thesis had an “improbable level of duplication” in the answers research participants gave to open-ended questions. Dong also allegedly confessed to a former supervisor that her husband impersonated participants in her studies and that she had failed to properly randomize the results – although the supervisor contests that Dong ever admitted this to her.

The dean who came to visit – and added dozens of authors without their knowledge

Earlier this year, a group of lecturers in Malaysia received a WhatsApp message from a colleague who had made a disturbing discovery.

The colleague, who wished to remain anonymous for this story, was looking through Google Scholar and noticed their name, and many others from their department, repeatedly appeared alongside that of an unfamiliar author: Kumba Digdowiseiso, dean of the economics and business faculty at Universitas Nasional in Jakarta, Indonesia.

“We didn’t even know who this person was,” said Safwan Mohd Nor, an associate professor of finance at the university, Universiti Malaysia Terengganu, adding that he was “extremely angry” when he first found out his name had been used.

High-profile ob-gyn accused of duplicating data threatens to sue critic

Sometime last summer, Ben Mol, an obstetrician-gynecology researcher in Australia, and his colleagues were adapting a European guideline on unexplained infertility when they came across a 2006 paper from Maria Luisa Casini, a pharmacologist in Rome, that gave them pause because of results that were not statistically significant.

When they looked further, they ended in a rabbit hole. Casini’s previous work revealed identical patient data across papers published two years apart, despite purporting to come from different groups of patients. The similarities were striking: In the 2006 paper, the women’s mean height was 165.5 centimeters; in the study published two years earlier that reported having more than triple the number of participants, the women had the exact same mean height, with the same standard deviation.

The guideline update would eventually lead to half of the included trials being flagged for integrity issues, and as a result, left out of the Australian version of the guideline. From that one paper by Casini that had initially raised doubts, the team was able to unearth a trail of suspicious data connected to several ob-gyns in Italy. An Italian medical society and one of the implicated authors have threatened to sue over the allegations, claiming the complaints were made to interfere with a high-profile society election, but the papers are now part of a wider Elsevier investigation.

Rejected paper pops up elsewhere after one journal suspected manipulation

In the autumn of 2022, a researcher in Turkey was reviewing a paper for a cardiology journal when an image of a Western blot caught her eye: A hardly visible pair of “unusual” lighter pixels seemed out of place. Magnification only bolstered her suspicion that something was off.

“This image made me think that the bands were cut one by one and pasted on a membrane background,” Şenay Akin, of Hacettepe University in Ankara, wrote in her comments to the editor of Cardiovascular Drugs and Therapy, a Springer Nature journal. “If this is the case, it indicates a manipulation [of] the results of this study.”

The editor, Yochai Birnbaum of Baylor College of Medicine in Houston, Texas, made a note to check the figure, adding below Akin’s comments in the editorial-management system: “I agree with the reviewer. It could be that the I/R band was manipulated.”

How a sleuth’s email turned a correction into a retraction

On Sept. 2, 2021, a professor at the University of Iowa, in Iowa City, emailed a biochemistry journal asking to correct a paper she had published the previous year. An experiment had “unintentionally” been omitted from a figure, Isabella Grumbach explained, and a comparison of experimental groups contained “a minor error in the degree of statistical significance.” A correction ensued.

But the problems with the article, “Inhibition of CaMKII in mitochondria preserves endothelial barrier function after irradiation,” appear to have been more deep-rooted than the email suggested. An anonymous commenter on PubPeer had first raised concerns about the article, which had appeared in Free Radical Biology and Medicine (FRBM), in July 2021, more than a year after it was published. The commenter claimed error bars between two figures were vastly different, even though they were meant to be related data points.

A cardiac surgeon’s tortuous efforts – including three lawsuits – to get the scientific record corrected

For the past 14 years, a cardiac surgeon in Italy has been trying to blow the whistle on a study written by his former colleagues that has been the subject of several investigations – with two of them finding problems with the data. And despite defeating three defamation lawsuits, two which were brought by authors of the paper, he’s not giving up yet.

The 2006 paper, ‘Relationship between atrial histopathology and atrial fibrillation after coronary bypass surgery’, written by several of cardiac surgeon Vittorio Mantovani’s colleagues at the Ospedale di Circolo in Varese, was published in the Journal of Thoracic and Cardiovascular Surgery. To date, the paper – which has been cited 57 times, according to Clarivate’s Web of Science – has been investigated by at least two institutions as well as the journal. None have resulted in a retraction, despite one university finding that only a little more than half of the patients in the dataset could be matched unambiguously with biopsy samples. One university is also waiting on the journal to act before it considers reopening its own investigation.

For Mantovani, the red flags started appearing in 2010, when he came across a minor discrepancy between two other papers written by him and his colleagues. He thought it was odd that in one dataset, patients were identified by name, but in the other, they were identified using numbers.
