伪造数据12年、20篇问题论文!校方:该实验室造假成风及荣誉教授头衔取消
研发家 | 2024-02-02 0

操纵、伪造实验数据长达12年之久(从2002年到2014年),俄亥俄州立大学教授Samson Jacob仍然熬到了名誉教授的荣休身份。而学校的一项学术不端调查,却让他名誉扫地。2021年5月,Samson Jacob被学校取消荣誉教授资格。俄亥俄州立大学表示Samson Jacob在研究中存在不当行为,并且他的实验室存在“放任数据操纵”的风气。校方表示“他已与大学没有任何关系”。

俄亥俄州立大学调查发现有20篇研究论文存在学术不端。截至到2024年1月30日,Samson Jacob被撤回17篇文章(在2023年12月15日被撤回4篇Cancer Research 文章)。

2021年2月,经过俄亥俄州立大学(Ohio State University)调查委员会长达5年、对67项指控的调查,公布了一份长达209页的调查报告。报告显示,在2002-2014年,Samson Jacob团队发表的论文中明显存在大量被操纵的图像,委员会确信“Samson Jacob实验室中存在一种允许的操纵数据文化,尤其是对照组数据,这不是由于疏忽造成的错误。”

调查发现有20篇研究论文存在学术不端。此前的2018年,雅各布等已被撤稿9篇,更正1篇。委员会要求,立即撤回其余的10篇,并建议对其进行制裁。

目前,委员会的建议正在实施中。2021年5月,Samson Jacob被取消退休职位。俄亥俄州立大学表示Samson Jacob在研究中存在不当行为,并且他的实验室存在“放任数据操纵”的风气。校方表示“他已与大学没有任何关系”。

委员会提出了3点建议:一是禁止雅各布进行所有研究、带研究生等其他研究者,并禁止在3年内提交联邦资助申请;二是撤销他的退休职位和杰出教师身份;三是要求自报告之日起的3年内,取消他的PI身份。
