Research Integrity and the use of Plagiarism detection software
How to create an iThenticate account?
Go to https://forms.lumc.nl/lumc2/walaeus_iThenticate, enter your LUMC credentials and submit the form. An account will be generated. iThenticate is accessible from any location.
Research Integrity and guidelines
Researchers flourish in a work environment that is characterized by independence and integrity. All employees of Leiden University Medical Center (LUMC), including PhD students, Bachelor and Master students and others, who are conducting research in collaboration with the LUMC, or using LUMC facilities, are expected to perform research according to the highest ethical and professional scientific standards.
From this perspective, scientific manuscripts, Master's theses and doctoral dissertations should be original and free from malversations such as plagiarism, falsification and fabrication.
More information about Research Integrity and guidelines addressing these issues can be found on the LUMC website Good Research Practice & Integrity.
To prevent incorrect citations and unintentional plagiarism there are two important documents available:
- Leidraad (in Dutch) published by Leiden University, containing Dos and Don’ts
- Correct Citation Practice published by the Koninklijke Academie voor Wetenschappen (KNAW).
Plagiarism detection software and what to do with the outcome
Incorrect citation and (unintentional) plagiarism can easily be detected and therefore eradicated by use of dedicated software programs such as Turnitin and iThenticate. Upon submission of a manuscript, these programs search for and report similarities checking an extensive range of scientific literature and education repositories.
At the LUMC, plagiarism detection software is freely available to all Master and Bachelor students (Turnitin) and to all Researchers, including PhD students (iThenticate). They are all expected to check their manuscripts and/or scientific output with this software before formal submission to examiners or journals.
Bachelor and Master students use Turnitin
LUMC’s plagiarism detection software for Bachelor and Master students is Turnitin.
Turnitin is integrated in Blackboard, so there is no need for these students to create a Turnitin account themselves. It has teaching module-specific workflows for students and examiners and also allows (re)submission deadlines, peer marking and grading.
Lecturers who discover possible plagiarism by students, are obligated to report this to the Exam Committee and provide them with the documents concerned, i.e. a paper, thesis or research assignment. The Exam Committee can then take disciplinary actions.
LUMC Researchers, including PhD students, use iThenticate
All research manuscripts and PhD theses should be checked for plagiarism by the authors themselves using iThenticate. iThenticate is from the same brand as Turnitin, but it does not have teaching module-specific workflows and does not allow for annotation, peer marking or grading. It does, however, have a document-sharing facility.
Researchers / PhD students themselves are responsible for scanning their manuscripts .
A "positive" scan result should be solved between the researcher and his/her Principal Investigator or between the PhD student and his/her Doctoral Advisor. If necessary, the Head of the Department may be consulted.
Every positive mark should be evaluated. In case of a citation, a definition, a method or a description etc. no action is needed. In other cases, it is up to the researcher and his supervisor to decide if a revision of the text is necessary.
We strongly advise you to keep the Ithenticate report and make a formal record of the evaluation process.
A PhD student needs to declare that he/she is familiar with the PhD Regulations Leiden University - Leiden University (universiteitleiden.nl) and will comply with the rules regarding a plagiarism-free dissertation and the standards of responsible research conduct, when registering in the Graduate School Management module (Converis).
The thesis should have been checked for plagiarism, before sending the manuscript to the Thesis Committee. After the check the PhD student needs to confirm that his or her research has been conducted in compliance with the given standards and that the manuscript is free of plagiarism. The confirmation is done in the Graduate School Management module (Converis).
How to create an iThenticate account
An iThenicate account must be created at https://forms.lumc.nl/lumc2/walaeus_iThenticate using your LUMC credentials and is accessible from any location.
There is also a training page where more information can be found.
EndNote is a useful software tool for inserting references and generation of a reference list.
The Walaeus Library has books about plagiarism and scientific integrity. These books are located in sections Q 175.37 en Q 180.55.M67. Books about correct citation can be found in section WZ 345.
