Dentistry student loses travel grant for duplicating his own work

iadrThe International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.

The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.

The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.

The IADR’s page now lists the winners with a note at the bottom: Continue reading Dentistry student loses travel grant for duplicating his own work

Psych paper falls afoul of journal’s plagiarism policy (hint: don’t plagiarize)

jcpharmacopharmThe Journal of Clinical Psychopharmacology has retracted a 2011 paper on depersonalization disorder by a pair of authors in Azerbaijan who got a bit too familiar with their source material without proper attribution. And the journal has offered its readers a handy — if depressingly obvious — admonition about publication ethics.

The article, “Lamotrigine in the immediate treatment of outpatients with depersonalization disorder without psychiatric comorbidity. Randomized, double-blind, placebo-controlled study,” by researchers at the Central Mental Clinic for Outpatients of Baku City, purported to find that: Continue reading Psych paper falls afoul of journal’s plagiarism policy (hint: don’t plagiarize)

Plagiarism charge bites authors of oral pain paper

jiohheader_imgThe Journal of International Oral Health has retracted a 2014 paper on dental pain by a group from India. Although the ostensible reason was plagiarism, we wonder if the offending authors might gone a bit further.

It has yet to be cited, according to Thomson Scientific’s Web of Knowledge. Here’s the abstract: Continue reading Plagiarism charge bites authors of oral pain paper
