Several works of Japanese novelist Kikuchi Kan are thought to be ghostwritten. Serialized novel Junange is one of them. According to the testimony of Kawabata Yasunari, Junange was written by Kikuchi Kan’s pupil, Yokomitsu Riichi. However, this claim remains unsubstantiated due to lack of evidence. In this paper, we verify Junange’s authorship using stylometric methods. We extracted three stylistic features from Junange and 64 novels written by Kikuchi and Yokomitsu. The three stylistic features, which have been reported effective in authorship attribution, are Usage of Comma, Part-of-speech bigram, and Phrase Pattern.

After converting these stylistic features matrices to the relative frequency ones by each work, we used hierarchical clustering analysis and principal component analysis as unsupervised methodologies, and integrated a classification algorithm comprising 7 strong classifiers, including support vector machine, random forest and XGBoost, as the supervised one, to define the authorship of Junange.

According to the results of the analyses mentioned above, we concluded that real author of Junange was Kikuchi Kan.

This research note briefly reviews some ideas about how people’s consciousness is associated with effective environmental protection behavior. This extends to culture, history and religion. Global environmental issues involve many complex factors such as economics, politics, humanitarianism, and religion. Furthermore, scientific measurements of the environment on a global scale are technically difficult and the data obtained are not always reliable. Therefore, many debates on global environmental protection are too complex to decide which is true or false. With all this in mind, we need to act as reasonably as calmly as possible without overreacting to the media and the advertising of extreme activists.

Based on fieldwork from 2013 to 2019 in Beichen Village, this research note examines thepresent situation and changes in China’s rural environment over the past decades. Apartfrom environmental problems such as garbage treatment and water pollution, infrastructure,culture, governmental policies, and rural residents’ consciousness were also reviewed. Thisresearch note aims to provide some basic information regarding local agricultural areas andhighlight certain features of rural environmental consciousness and behaviors. Some cluesregarding the direction of statistical surveys in the future have also been proposed.

In response to the 2030 Agenda for Sustainable Development adopted by the UN GeneralAssembly in September 2015, the government-initiated 17 Sustainable Development Goals(SDGs) and Public Opinions are being implemented in Japan. This is our effort to findsolutions for poverty, hunger, energy shortages, climate change, and all global issues. Basedon the results of several opinion surveys, this paper considers the Japanese way of life, especiallyregarding gender and nature. The research reports discuss our views on feasibleapproaches to achieve the SDGs as well as the recent trend of pro-environment attitudesand awareness in Japan. Working towards the SDGs will allow many countries to focustheir attention on the issues within their borders.
