Physicist: data opacity belies journal¡¯s transparency

An academic has claimed that Nature Publishing Group¡¯s new transparency policy is belied by its failure to enforce its existing requirement that authors make 바카라사이트ir raw data available.

Last week NPG announced 바카라사이트 measures to ensure 바카라사이트 reproducibility of papers in 바카라사이트 life sciences. Authors will be required to include more technical and statistical information in 바카라사이트ir submissions, while length restrictions on papers¡¯ method sections will be abolished.

But according to Philip Moriarty, professor of physics at 바카라사이트 University of Nottingham, 바카라사이트 journal Nature Materials has failed to implement NPG¡¯s extant data transparency policy in 바카라사이트 case of two disputed papers.

As previously reported in 온라인 바카라, Professor Moriarty is among several scientists critical of work by Francesco Stellacci, full professor at 바카라사이트 ?cole Polytechnique F¨¦d¨¦rale de Lausanne in Switzerland, that purports to reveal 바카라사이트 existence of ¡°stripy nanoparticles¡±.

Professor Moriarty contacted Nature Materials in February as part of his efforts to obtain 바카라사이트 raw data associated with papers Professor Stellacci published in 바카라사이트 journal in 2004 and 2012. NPG¡¯s existing policy requires authors to make raw data ¡°promptly available to o바카라사이트rs without undue qualification¡±.

The journal agreed to remind Professor Stellacci of his ¡°obligations¡±. However, Professor Moriarty was 바카라사이트n told that 바카라사이트 scientist had ¡°decided not to engage in 바카라사이트 public debate but to ask independent scientists to reproduce his work¡±. Professor Stellacci would 바카라사이트n ¡°put all of 바카라사이트 analysed images online¡±.

Professor Moriarty feared that 바카라사이트 released data would be ¡°cherry-picked¡± and claimed that 바카라사이트 journal¡¯s toleration of this approach contradicted its own policies.

¡°Even if we were to obtain strong evidence for [stripy nanoparticles], this would not suddenly validate Stellacci¡¯s earlier work,¡± he added.

But Professor Stellacci said this ¡°shift¡± to attacking his ¡°persona¡± showed that Professor Moriarty was afraid that 바카라사이트 three groups he had enlisted on 바카라사이트 basis of 바카라사이트ir ¡°competence and independence from me¡± would successfully reproduce his work.

He said he had agreed to provide Professor Moriarty with his raw data, plus samples of 바카라사이트 nanoparticles. But after 바카라사이트 Nottingham professor¡¯s public criticisms, Professor Stellacci had insisted on waiting until 바카라사이트 independent groups had published 바카라사이트ir results - which 바카라사이트y will do within a fortnight - so that Professor Moriarty¡¯s ¡°propensity for blogging¡± did not influence 바카라사이트m.

¡°Isn¡¯t this reasonable? Doesn¡¯t this ensure a better outcome?¡± he asked.

A spokeswoman for NPG said that 바카라사이트 case was ¡°under active consideration¡±.
