* a.k.a. Anti-plagiarism Thesis seminar lectures, Nov 24th, 2016 Martti Tolvanen 1 * Knowledge does not exist in isolation * but it is related to previous knowledge * Science is a process of creating new knowledge * Hypothesis: an assumption of how something might be * Hypothesis testing: experiments or data analysis * Theory: a larger, consistent framework of proven and unproven hypotheses * When writing, you need to make clear how your work relates to previous theories and tradition * 2 * How to give credit to previous work: * References to publications * How do we know that previous work is valid? * Peer review: other scientists review the manuscripts for journal articles * Books: highly esteemed authors and/or editors * How do you select each reference? * Try to find the most original statement and/or experiment to support what your text says * 3 * Plagiarism: representing somebody else’s ideas or work as your work * Very rare and hard to do at experiment level * Easy to do at the level of writing * But: what is copying, what is paraphrasing? * Self-plagiarism: repeating your own results or text * Ok in ”review articles” * Ok in specific situations * Expanding MSc thesis into PhD thesis * 4 * Science is competitive * ”Publish or Perish” * Reports and rumors circulate of people stealing data and ideas from another research group * and publishing the results first * = intellectual theft * Normally science is collaborative and open * But you should be aware of which of your ”competitors” are considered hostile and which are friendly * 5 * What is the degree of acceptable imitation in text? * In some cultures changing somebody else’s words is seen as disrespect * In the European tradition of science, exact quotes are avoided * What is acceptable in actual work? * Repeating an experiment with small modifications: validation or plagiarism? * Is it more acceptable if the original experiment was yours or somebody else’s? * 6 * In writing, it’s important that you develop your original approach and/or outline * Do not follow somebody else’s train of thought for very long * Whenever you state specific scientific facts, they should be backed by references * Unless ”textbook-level” or ”everybody knows” * You should write in your own words * paraphrasing * 7 * Starting from Jan 2013 (PhD theses) and Aug 2013 (MSc theses) every thesis at the U of Turku requires a check for originality * After the check, you will be required to include this text at the bottom of the title page: * ”The originality of this thesis has been checked in accordance with the University of Turku quality assurance system using the Turnitin OriginalityCheck service.” * 8 * The selected tool for anti-plagiarism check: Turnitin * Market leader, used widely * Including U of Turku and U of Tampere * The student submits his/her text in the system * Interface in Moodle, actual check in the Turnitin servers * Your text is checked against a huge database of existing texts * 9 * Output: a report in which all detected similarities are highlighted * Most similarities are insignificant * The service is trained to note small insertions or deletions, or even changes in word order, so even many well paraphrased ideas are highlighted * Scientific text can not avoid the repetition of precise terms * 10 * 11 * 12 * 13 * 14 * 15 * 16 * 17 * What was not quite right in the previous example? 18 * My opinions * Lazy writing, follows quite closely the original * Well paraphrased, though * Citation not shown together with the statements * What you couldn’t see * Comparison to a non-academic publication? * (Women's Health Weekly, Oct 9 2008) * 19 * What I didn’t see at the time of the check (and neither did TurnItIn) 20 * Further opinions? * Did the Women’s Health author plagiarize the article abstract more heavily than the thesis writer? * 21 * The original article was properly cited a bit later * 22
