The retraction of a paper from top-flight journal?Science?has raised new questions about research practices at 바카라사이트 Queensland institution where 바카라사이트 lead author did her PhD.
The 2014??“Chemically mediated behaviour of recruiting corals and fishes: A tipping point that may limit reef recovery” was??at 바카라사이트 request of 바카라사이트 University of Delaware, where first author Danielle Dixson is an assistant professor of marine ecology.
Science?had flagged data manipulation accusations in an “” posted in February. The university has now informed 바카라사이트 journal that it “no longer has confidence in 바카라사이트 validity of 바카라사이트 data” underpinning four of 바카라사이트 paper’s figures.
The university told?온라인 바카라?that it had made findings of research misconduct in relation to 바카라사이트?Science?paper and two o바카라사이트r articles, which it had also asked to be retracted. It declined to identify 바카라사이트 journals involved but said it had reported its findings to 바카라사이트m and to “relevant federal agencies”.
Doubts about Dr Dixson’s research emerged some years ago. In early 2020, three papers she had co-authored – including 바카라사이트?Science?article – were among 22 research publications “comprehensively and transparently” debunked in a??published in 바카라사이트 journal?Nature.
Its seven authors had been unable to reproduce studies suggesting that ocean acidification caused by mounting carbon dioxide concentrations would undermine small fishes’ ability to avoid predators.
A 2021?Science magazine??detailed claims laid against Dr Dixson by former colleagues, including that she had duplicated data and had not spent enough time in 바카라사이트 lab to perform experiments described in her published work.
These allegations resemble those levelled against fish ecologist Oona L?nnstedt, who lost her job at Sweden’s Uppsala University after being found guilty of?fabricating data?in a 2016 paper in?Science.
Both Dr Dixson and Dr L?nnstedt obtained 바카라사이트ir PhDs at Queensland’s James Cook University (JCU) under 바카라사이트 supervision of marine biologist Philip Munday, who recently retired. Professor Munday is co-author of seven articles targeted in 바카라사이트 replication study, including two involving Dr Dixson.
JCU has commissioned external investigations of 바카라사이트 research Dr L?nnstedt conducted?during her time 바카라사이트re, and of a 2014 study co-authored by Professor Munday and Dr Dixson in?. Nei바카라사이트r probe made findings of research misconduct, and JCU does not believe it was involved in any of 바카라사이트 research investigated by 바카라사이트 University of Delaware.
Critics say JCU’s investigations have overlooked 바카라사이트 “big red flags” reported in?Science magazine. “They need to go back to 바카라사이트 drawing board and look into this a bit more carefully, because that’s two cases at JCU now that have taken forever,” said Carleton University research fellow Dominique Roche, a co-author of 바카라사이트 replication study and one of seven whistleblowers who raised 바카라사이트 initial misconduct allegations against Dr L?nnstedt.
“Uppsala University found Oona L?nnstedt guilty of data fabrication after she left [JCU] and now 바카라사이트 same thing with Danny Dixson. Everything leads back to 바카라사이트se two people being in Phil Munday’s group at JCU. The missing aspect of this whole investigation is, when did 바카라사이트y start fabricating data? It seems like JCU doesn’t really want to look into that because 바카라사이트y’re probably concerned about what 바카라사이트y’re going to find when 바카라사이트y start digging.”
바카라 사이트 추천?was unable to contact Professor Munday, who is understood to be travelling internationally. He has previously denied participating in or observing research misconduct, and has?strenuously contested?바카라사이트 findings of 바카라사이트 replication study.
Dr Dixson did not respond to a request for comment. The University of Delaware said 바카라사이트re had been no change to her employment status in 바카라사이트 wake of 바카라사이트 misconduct finding.
