Papers with simpler abstracts are cited more, study suggests

J informetricsResearch papers containing abstracts that are shorter and consist of more commonly used words accumulate citations more successfully, according to a recent study published in the Journal of Informetrics.

After analyzing more than 200,000 academic papers published between 1999 and 2008, the authors found that abstracts were slightly less likely to be cited than those that were half as long. Keeping it simple also mattered— abstracts that were heavy on familiar words such as “higher,” “increased” and “time” earned a bit more citations than others. Even adding a five-letter word to an abstract reduced citation counts by 0.02%.

According to Mike Thelwall, an information scientist at the University of Wolverhampton, UK, who was not a co-author on the paper: Continue reading Papers with simpler abstracts are cited more, study suggests

More retractions bring total to 7 for neuroscience pair, 2 more pending

JOCNAuthors have retracted two papers about visual perception and working memory from the Journal of Cognitive Neuroscience, after the first author admitted to falsifying or fabricating data in four other papers.

The authors have requested another two retractions, as well, which will bring the total for Edward Awh and his former graduate student David Anderson to nine retractions. (Earlier in 2015, they lost a paper due to an error in the analytic code, which Awh told us was unrelated to the misconduct.)

The retraction notice attached to both articles cites a 2015 settlement agreement between the Office of Research Integrity and first author Anderson (the “respondent”), who admitted to misconduct while working as a graduate student in the lab of Awh at the University of Oregon in Eugene. Since then, “additional problems” were discovered in the newly retracted articles, such as removed data points.

Awh, who has since moved to the University of Chicago, sent us a lengthy statement, explaining the concerns about each article: Continue reading More retractions bring total to 7 for neuroscience pair, 2 more pending

Researchers’ productivity hasn’t increased in a century, study suggests

Screen Shot 2016-01-19 at 10.50.25 AMAre individual scientists now more productive early in their careers than 100 years ago? No, according to a large analysis of publication records released by PLOS ONE today.

Despite concerns of rising “salami slicing” in research papers in line with the “publish or perish” philosophy of academic publishing, the study found that individual early career researchers’ productivity has not increased in the last century. The authors analyzed more than 760,000 papers of all disciplines published by 41,427 authors between 1900 and 2013, cataloged by Thomson Reuters Web of Science.

The authors summarize their conclusions in “Researchers’ individual publication rate has not increased in a century:”

Journal bans 8 authors for plagiarism

67

A medical journal has banned eight authors after discovering that they had published plagiarized work.

We don’t see official author bans as often as we see plagiarism (occasionally, and all the time, respectively). That’s why we’re flagging this case, which is a little old — the International Journal of Medical Science and Public Health announced the ban in March 2015, after it retracted three of the authors’ papers for plagiarism.

All three papers — about recovering from orthopedic problems — have a first author in common: Rajesh Valjibhai Chawda, who was affiliated with the CU Shah Medical College and Hospital in India at the time of the research. (We couldn’t find a webpage for him.)

After an author on one of the original articles alerted the journal of one instance of plagiarism, the journal launched an in-house inquiry, the retraction note explains:

Authors retract striking circadian clock finding after failing to replicate

Screen Shot 2016-03-02 at 9.29.28 AMThe authors of a paper showing a “striking and unanticipated” relationship between light and temperature in regulating circadian rhythms are retracting it when the results couldn’t be replicated.

After being contacted by another group who couldn’t reproduce the data, the authors failed to, as well. They “have absolutely no explanation for the discrepancies with the original results,” according to the note in PLOS Biology.

It’s an unfortunate turn of events, but Continue reading Authors retract striking circadian clock finding after failing to replicate

It’s one of multiple papers by lead author Leonard Guarente that have been questioned on PubPeer. Guarente has already retracted one, and plans to address another. Continue reading Popular paper by famous longevity researcher gets mega-correction

We’re using a common statistical test all wrong. Statisticians want to fix that.

ASA-newlogoAfter reading too many papers that either are not reproducible or contain statistical errors (or both), the American Statistical Association (ASA) has been roused to action. Today the group released six principles for the use and interpretation of p values. P-values are used to search for differences between groups or treatments, to evaluate relationships between variables of interest, and for many other purposes.  But the ASA says they are widely misused. Here are the six principles from the ASA statement:  Continue reading We’re using a common statistical test all wrong. Statisticians want to fix that.

PLOS ONE retracting paper that cites “the Creator”

More than half of top-tier economics papers are replicable, study finds

scienceApproximately six out of 10 economics studies published in the field’s most reputable journals — American Economic Review and the Quarterly Journal of Economics — are replicable, according to a study published today in Science.

The authors repeated the results of 18 papers published between 2011 and 2014 and found 11 — approximately 61% — lived up to their claims. But the study found the replicated effect to be on average only 66% of that reported in the earlier studies, which suggests that authors of the original papers may have exaggerated the trends they reported.

Colin Camerer, a behavioral economist at the California Institute of Technology in Pasadena, who co-authored the study, “Evaluating replicability of laboratory experiments in economics,” told us: Continue reading More than half of top-tier economics papers are replicable, study finds

Sample tampering leads to plant scientist’s 7th retraction

Jorge Vivanco
Jorge Vivanco

Plant scientist Jorge Vivanco has earned his seventh retraction, after an investigation found data from soil samples were “intentionally fabricated by a third party.”

Vivanco and his former postdoc Harsh Bais made a name for themselves by discovering the secret behind a nasty invasive plant: It secretes a harmful form of catechin, which kills everything around it, suggesting it could serve as a new herbicide. The findings earned the researchers a story in the New York Times.

In the newly retracted paper, published in 2005, first author Laura Perry — then a postdoc at Colorado State University — further explored the role of the plant-killer, working with Vivanco as the last author. However, when a team working in the building next door had trouble finding catechin in their samples, Perry took another look, and concluded that her samples had been tampered with.

In other words, Perry told us:   Continue reading Sample tampering leads to plant scientist’s 7th retraction
