The Handling of Personal Information in Mobile Games

Stefan Brückner; Yukiko Sato; Shuichi Kurabayashi; Ikumi Waragai

The management of personal consumer information by corporate entities is a politically and socially sensitive subject. This paper examines how personal information is handled by mobile game developers and displayed inside mobile games. 38 mobile games from 29 developers were examined, chosen based on their popularity as expressed by the rankings in the Google Play store. An investigation was made into the type of information that is required during the registration process, what information is optional, and what information is finally displayed in the game and to whom. In a second step, the privacy policies of the 29 mobile game developers were compared, examining them for differences in content. Lastly, the reaction of game developers to written requests for information disclosure and deletion was investigated. Results suggest that how personal information is displayed in-game is largely dependent on the game genre. Privacy policies, while following the same template, differ in how detailed they are held. Lastly, replies to inquiries about information and requests for deletion varied greatly and sometimes were at odds with a company’s privacy policy. This investigation indicates the necessity of accumulating and sharing know-how and best practices for the design of privacy policies and the proper handling of personal information.

Media and religious language — Comparative text analysis in German, English and Japanese about the 3.11 earthquake, tsunami and fukushima catastrophe in Japan 2011

Yukiko Sato; Ikumi Waragai

The choice of expressions used in news reports is dependent on their language, the perspective of the journalist and the purpose of the news. Previous research by Miyata (2002) and Chomsky (2003) shows that religious language has often been used in the media to convey political ideas and legitimize political acts to the public. Based on that theory this research will try to clarify the reasons for utilizing religious language as a method of expression when delivering news articles about the 2011 catastrophe in Japan. Religious language, which in the context of this paper refers to expressions originating from a Christian context, appears in Western news reports, even when reporting about secular events. This study will investigate Japanese, American and German newspaper articles, related to the 2011 Tohoku earthquake in Japan, since Germany and the USA have different cultural as well as religious backgrounds compared to Japan. It aims to analyze the use and function of religious (Christian) expressions, especially religious metaphors and symbols, and to clarify how religious elements can change perception of an article, concerning the Earthquake, Tsunami and Fukushima nuclear disaster. In total 540 articles in Japanese, German and English were analyzed. 37961 words, 2400 sentences and 36 pictures appearing in German and American national newspapers, printed from 2012 to 2016, were taken into account through a critical discourse analysis. 40 religious elements were found. Religious language is mostly used symbolically as well as metaphorically in order to illustrate the devastation caused by the earthquake, tsunami and nuclear disaster, as well as the suffering and hope of the victims. Furthermore, in Germany, religious language employed in news articles concerning the catastrophe in Japan also serves to emphasize domestic social and political problems.
