Chapter III – Definition of Plagiarism

Art. 4 For the purposes of this policy, plagiarism is defined as the unauthorized appropriation of intellectual work, by any means, without proper attribution, as defined by Wachowski and Costa (2016, p. 110):

“[...] essentially an ethical issue that consists of the act of appropriating, by any form or means, an intellectual work of another person, presenting it as one’s own. [...] It is the improper appropriation of a text, a piece of music, a painting, or any other intellectual work, in which the usurper assumes authorship, deliberately omitting credit to the original author.”
