Plagiranje kao povreda znanstvene i akademske čestos Plagiarism as a violaon of scienfi c and academic integrity

Plagiarism is unauthorized appropriaon of other people's ideas, processes or text with- out giving correct credit and with intenon to present it as own property. Appropriaon of own published ideas or text and passing it as original is denominated self-plagiarism and considered as bad as plagiarism. The frequency of plagiarism is increasing and development of informaon and communicaon technologies facilitates it, but simultaneously, thanks to the same technology, pla- giarism detecon soware is developing. There are diff erent soware soluons for checking plagiarism. Most of them are based on concor- dance, i.e., comparison of text where program tools isolate and mark correspondent parts of the text and calculate its rate regarding the whole text. Several programs, besides comparing the texts, also search the Internet aiming for text with corresponding content. All programs can compare text wrien in the same language but translingual comparison with plagiarism detecon soware is not yet possible. The soware is available through computer programs (WCopyfi nd) or Web Services (eTBlast, CrossCheck). Their advantage is in the possibility of fi nding the original source paper. eTBlast is the free of charge web based service for searching corresponding and highly similar scien- � fi c paper abstracts (it searches also Medline database), which served as the ground for construct- ing Deja vu database. Web based service CrossCheck is accessible only for members (academic ins� - tuons and journals) and by using computer similarity algorithm iThencate of company iParadigms (Oakland, CA, USA), it checks accordance of the given text with the complete texts in the CrossCheck database. It is organized by collaboraon of journal editorial boards and publishers who pass the published papers to the base and enable searching of content usually protected by subscripon. The importance of recognizing and teaching plagiarism in the academic community at all levels of educaon is enormous. Scienfi c journal editors and sciensts should fi ght together against unethi- cal researches which are opposite to the scienfi c idea and harmful for scienfi c community and so- ciety, crically read and examine scienfi c publicaons, report plagiarism and other suspicious re- search misconduct to journal editorial boards and instuonal authories. 1 Katedra za medicinsku informaku Medicinskog fakulteta Sveucilista u Rijeci 2 Zavod za laboratorijsku dijagnosku Klinickog bolnickog centra Rijeka 3 Klinicki zavod za laboratorijsku dijagnosku Klinicke bolnice Dubrava u Zagrebu
