    This paper examines the impact of civil law system on modern China legal reform. The adontion of the civil law system in modern China began in the late Qing Dynasty. In order to reform the judicature, the Qing government transplanted the western laws on a large scale, especially the laws of Japan. There were an umber of factors involved foreign,social, cultural, political, and legal. On the whole, it can be summarized as two major aspects. On the one hand, the western civil law codes had apparent advantages, and Japanese law system has achieved great success, caught a high degree of attention of the Chinese intellectual circle at the time. On the other hand, through a wide range of translation, introduction and education, civil law system was widely noticed and exerted a great influence, with the help of Japanese legal experts were hired by the late Qing government. The late Qing efforts to adopt the continental law system had an important and far-reaching impact on the development of legal system of Republican China by the initiatires of Nanjing government.東アジアの歴史と動態文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠

    According to previous studies, Japanese compound verb is one of the greatest challenges faced by Japanese language learners, Regarding the acquisition of Japanese compound verb, the criteria of combining the first verb(V 1)and the second verb(V 2)as well as the difference in meaning between a single verb and a compoulld verb have been taking up as crucial issues. Before developing teaching pedagogies and teaching materials, it is necessary to find out what are the difficult compound verbs for the learners.・This paper lnvestlgates the comprehension of compound verbs of learners in Hong Kong who passed level l of the Japanese Language Proficiency Test. From the result, firstly, it is found that there is a difference between the recognition and the usage of compoulld verbs. Besides, between the meaning of V l and V 2 as two single verbs and as a compound verb, there is a gap which makes it difficult to learn. Moreover, there are occasions that learners are unable to distinguish similar compound verbs. Therefore, it is essential to draw out curriculum and guidelines while paying attention to all mentioned above

    本文探究中国股票特质波动率与横截面收益之间的关系,以沪深A股从2000年到2014年共782周的周度收益率数据为样本,结合最新的Fama-French五因子模型,通过滚动窗口回归的方法得到每只股票的特质波动率,再用分组法和Fama-Macheth回归来检验当期的特质波动率对接下来一到五周的股票横截面收益是否有一定的预测能力。研究表明,股票特质波动率与横截面收益率呈正相关关系,但这种相关关系在分组法下并不显著,因此股票的特质波动率在实践中并不能用来预测股票收益率,这从侧面证明了中国股市的有效市场假说
