You’ve been dupe’d: Results so nice, they’re published twice

without comments

obesity surgeryWith retraction notices continuing to pour in, we like to occasionally take the opportunity to cover several at a time to keep up.

We’ve compiled a handful of retractions that were all issued to papers that were published twice by at least one of the same authors — known as duplication. (Sometimes, this can be the publisher’s fault, although that doesn’t appear to be the case in any of the following examples.)

So here are five recently retracted papers that were pulled because of duplication: Read the rest of this entry »

You’ve been dupe’d: Results so nice, journals published them twice

without comments

With so many retraction notices pouring in, from time to time we compile a handful of straight-forward retractions.

Once again, this list focuses on duplications — but unlike other duplications, these authors were not at fault. Rather, these retractions occurred because the publishers mistakenly published the same paper twice — the result of a transfer between publishers, for instance, or accidentally publishing the unedited version of the paper. We’re forced to wonder, as we have before, whether saddling researchers’ CVs with a retraction is really the most fair way to handle these cases.

So without further ado, here’s five cases where the journal mistakenly duplicated a paper, and had to retract one version: Read the rest of this entry »

You’ve been dupe’d: Nice data — let’s see them again

without comments

As we’ve said before, with hundreds of retractions per year, there are simply too many for us to cover individually.

So from time to time we’ll compile a list of retractions that appeared relatively straightforward, just for record-keeping purposes.

Often, these seemingly straightforward retractions involve duplications, in which authors — accidentally or on purpose — republish their own work elsewhere.

Sometimes journals and authors blame this event on “poor communication,” our first example notes:

You’ve been dupe’d (again): Do these data look familiar? They are

with one comment

plant_growth_regulationWe can’t keep up with the growing number of retraction notices, so we’ve compiled a list of recent duplications to update our records.

1. Authors don’t always intentionally duplicate their own work, of course. The first paper on our list was retracted after the authors included a figure from a previous paper by accident, according to the publisher: Read the rest of this entry »

You’ve been dupe’d: Meet authors who like their work so much, they publish it twice

fertility and sterility

When our co-founders launched the site in 2010, they wondered whether there would be enough retractions to write about on a regular basis. Five+ years and three full-time staffers later, and we simply don’t have the time to cover everything that comes across our desk.

In 2012, we covered a group of duplication retractions in a single post, simply because duplications happen so frequently (sadly) and often don’t tell an interesting story. So in the interest of bookkeeping, we’re picking up the practice again.

Here are five unrelated retractions for your perusal: all addressing duplications, in which the same – or mostly the same – authors published the same – or mostly the same – information in two different – or sometimes the same – journals.

So, on the buffet table we offer the following entrees: Read the rest of this entry »

You’ve been dupe’d: Catching up on authors who liked their work enough to use it again

As we’ve noted before, we generally let duplication retractions make their way to the bottom of our to-do pile, since there’s often less of an interesting story behind them, duplication is hardly the worst of publishing sins, and the notices usually tell the story. (These are often referred to — imprecisely — as “self-plagiarism.”)

But that skews what’s represented here — boy, are there a lot of duplication retractions we haven’t covered! — and we might as well be more comprehensive. Plus, our eagle-eyed readers may find issues that we won’t see on a quick scan.

So with this post, we’re inaugurating a new feature here at Retraction Watch, “You’ve been dupe’d.” Every now and then, we’ll gather five of these duplication retractions at a time, and post them so they get into the mix, and into our category listing (see drop-down menu in right-hand column if you haven’t already). Here are the first five: Read the rest of this entry »

A new record: A retraction, 27 years later

with 8 comments

jsbmbIn October, we noted the apparent record holder for longest time between publication and retraction: 25 years, for “Retention of the 4-pro-R hydrogen atom of mevalonate at C-2,2′ of bacterioruberin in Halobacterium halobium,” published in the Biochemical Journal in 1980 and retracted in 2005. (Although an author requested that another 52-year-old paper be retracted, it remains untouched in the literature.)

That record has now been broken. Congratulations to the Journal of Steroid Biochemistry and Molecular Biology and the authors of a December 1985 paper, “Increasing the response rate to cytotoxic chemotherapy by endocrine means.” Here’s the notice, which appears in the January 2013 issue of the journal, making 27 years — and a month, if you’re counting: Read the rest of this entry »
