学位論文「コピペ当然」の風土をいかに変えるか - 高橋真理子｜WEBRONZA - 朝日新聞社
This title is "How do we change the culture of Japanese-plagiarism?". This article is based on the problem of "STAP cell". The first author who wrote the papers about "STAP cell" was famous for the plagiarism in her doctoral paper, and a lot of plagiarism has found in other researchers' doctoral papers. Some professor said, "It is natural", in this article.
Two roots, I found: Japanese history and Japanese education.
First, Japanese history has composed of "plagiarism". In Meiji-Era, Japanese culture was fully changed by the civilization and enlightenment, from "Samurai" to "Jentle-man". They chose not only to cut his original hair ("Tyon-mage") but to plagiarize cultures. Additionally, "Kyoto" resulted from the plagiarism. The Kyoto as a capital city, called "Heian-kyo" was made up like "Tyooan", Tyooan is the old capital city in China. So Japanese has chosen to plagiarism in the cultural point.
Secondly, Japanese education also compose of "plagiarism". Japanese like only-one answer and dislike the others. Japanese are famous for their accuracy, for example, only 1-second-delay must require the apology in Japan. We can easily and easily hear these apologies in the train or the restaurant. "O-mo-te-na-si" results from the apology. To examine the apology-phenomenon, Japanese like only one answer, "Never delaying".
As a result, Japanese are made to learn only-one-answer in each problems.
In fact, many Japanese students plagiarize at their homework or their test. The ability to copy only-one-answer is only one index in their school and the amount of their work is too much to solve by thierselves.
On Japanese history and education, Japanese plagiarism culture is as a logical consequence.
