    本研究は、中国で学ぶ中国語母語話者を対象に、日本語聴解テストにおける選択肢提示形式の影響を考察したものである。研究の目的は、1)選択肢を文字で提示したテストと音声で提示したテストとでは、結果に違いが生じるか、2)文字提示形式と音声提示形式との間で正答率について有意差が確認された項目は、どのような特徴があるか、という点について考察することである。 調査協力者は、文字提示形式のテストを受験した63名と音声提示形式のテストを受験した63名である。テスト項目のうち、実験項目は24項目であった。統計的分析の結果、文字提示形式と音声提示形式、それぞれの得点の平均値には有意差がないことが明らかになった。しかし、実験項目の各項目について統計的分析を行った結果、文字提示形式のほうが正答率が高い項目が4項目、音声提示形式のほうが高い項目が1項目認められた。そこで、この5項目について、その要因を探るために、4名の協力者を対象にインタビュー調査を実施した。その結果、文字条件が有利となる項目は、a)学習者になじみのない語が正答選択肢に含まれている、b)設問から推測される選択肢内容と実際の選択肢内容が異なる、という特徴を有していた。音声提示形式のほうが有利となる項目については、その要因は特定できず、可能性を指摘するにとどまった。本研究の結果は、中国語母語話者にとっては、文字による選択肢が有利に働くであろうという予測を覆すものであった。これは、中国の学習者は、文字を読みながら聞くという言語行動に慣れていない、日本語能力試験の対策を行っているため音声提示形式の聴解問題に慣れている、などの理由が考えられる。This study aims to investigate the effect of multiplechoice option presentation style in written and recorded formats on the results of a Japanese listening comprehension test for native speakers of Chinese studying in China. Sixty-three examinees underwent a listening test consisting of twenty-four items with written response options, and sixty-three examinees underwent a listening test consisting of twenty-four items with recorded response options. The results showed that there was no significant difference in the mean scores of the two styles. However, an analysis of each item revealed that four items appeared less difficult when the response options were printed and one item was perceived as less difficult when the options were presented in a recorded format. Four participants underwent a test comprising these five items and were asked to answer each question after listening to it. The results of the analysis were as follows: (a) items whose correct answer included a word unfamiliar to the examinees were less difficult in the written format and (b) items whose answer students could not discern after listening to the question were less difficult in the written format. The reason for one item being less difficult in the recorded format was not found. Contrary to the hypothesis, the result indicated that the style in which the options were presented in the written format was not less difficult for Chinese learners. A possible explanation for this is that Chinese studying in China are not familiar with listening andreading simultaneously, and are used to listening comprehension tests whose options are presented in a recorded format as practice for the Japanese-Language Proficiency Test

    Could Marine Industry Promote the Coordinated Development of Coastal Provinces in China?

    The marine economy, as an important driving force for economic development in coastal countries and regions, is now generally accepted by the academic world. This article examines the economic impact of the marine industry on China’s coastal provinces and cities and focuses on the narrowing development gap the marine industry faces in the coastal provinces and cities to promote the coordinated development of China’s coastal zone. It will further analyze the spatial and temporal differentiation of the marine industry along with what has driven China’s regional economic growth from 2006 to 2015. The research has proven that the marine economy certainly has a tremendous impact on provincial economic growth in coastal provinces (cities) and that even its degree of promotion is different in different cities. Further findings state that the contribution rate of the marine economy to the provincial economy in Tianjin, Shanghai, Fujian, Shandong, Guangdong, and Hainan is higher than the national average rate. Related findings are conducive to gain a better understanding of how development can be balanced and what best scientific decision-making practices can be utilized by policy-makers and planners in China

    Surfactant-free, H<sub>2</sub>-reduced Pt NPs were successfully fabricated on the surface of Fe<sub>3</sub>O<sub>4</sub>. Characterizations disclosed that Pt NPs (3.1 nm on average) dispersed evenly on Fe<sub>3</sub>O<sub>4</sub>. This catalyst is extremely active and selective for hydrogenation of chloronitrobenzenes, convenient, and suitable for cyclic utilization. The study showed that the activity of Pt depended mainly on its particle size and that the Fe<sub>3</sub>O<sub>4</sub> support is most favorable for this reaction
