Japanese Prime Ministers of the Heisei Era : Portraits of the 16 Leaders
Get PDFThis article is a record of lectures on Japanese prime ministers who appeared in the approximately 30 years of the Heisei era. First, Akio Watanabe amongst other prime ministers, mainly discussed Kiichi Miyazawa, comparing him with Hayato Ikeda and Masayoshi Ohira. Next, Noriko Akiyama talked about her observations on the personalities of Ryutaro Hashimoto, Keizo Obuchi, Junichiro Koizumi, Yoshihiko Noda and, Shinzo Abe, based on her interviews with these leaders. Taizo Miyagi discussed the characteristics of Heisei era in the context of Japanese political history and international relations over the Asia-Pacific region.departmental bulletin pape
What the Highway Remembers : Route 66 and America
Get PDFThis thesis analyzes the harsh reality laid on the reverse side of the American dream that John Steinbeck vividly described in The Grapes of Wrath (1939). Steinbeck obviously underscores that the United States, which is the land of the American dream, has taken the wrong route and put unfortunate people like the Dust Bowl migrants in a cruel predicament. Has this country rightly come back to the path which it was supposed to take from the outset as the promised land, or is it still taking the wrong course even now? Route 66, which the protagonist Tom Joad and his family take in the novel, still winds through people’s fantasies today even after it was officially removed from the United States Highway System in 1985. Why are people still fascinated with this old highway? What has this highway witnessed about American history? Running along this highway with the Joad family, and with Woody Guthrie and Bruce Springsteen who sing for oppressed people, I will examine the present state of the country by analyzing Jessica Bruder’s Nomadland (2017) to see how things have changed since the 1930s. Is the American dream still alive? Is California still a promised land for American people? What lessons have been learned from the Dust Bowl, which dispossessed the Joad family? Route 66 has been a witness to so many aspects of American history. The highway itself carries its own memories while continuing to capture the imagination of so many others even today.departmental bulletin pape
Carbon Dioxide Utilization Techniques Using Concrete Wastes
Get PDFConcrete is widely used as a construction material worldwide. Effective recycling and utilization of concrete waste are of great importance to improve our society. Approximately one third of concrete is chemically reactive and strongly alkaline hydrate cement, which can be used for fixation of CO2 as stable carbonate compounds. In this article, the reaction mechanism and advantages of concrete carbonation are summarized, and an indirect carbonation process for concrete sludge and a direct carbonation process for demolished concrete waste are introduced.departmental bulletin pape
Evaluation of Salt-affected Soil Amelioration by Using Waste Concrete and Cement Fine Powder in China
Get PDFSalt-affected soils are widespread in countries with arid and semiarid regions, and a decrease in agricultural production due to excessive salts is a very serious problem. In China, we have performed a salt-affected soil amelioration with flue gas desulfurization gypsum (FGDG) since 1996. Otherwise, the accelerating urbanization has led to a large number of demolitions of infrastructures in China. Therefore, the need for the recycling and reuse of not only FGDG but also waste concrete (WC) is a pressing issue. In this study, changes in physicochemical properties in the salt-affected soil amelioration with FGDG, cement fine powder (CFP), and waste concrete particles (WCP) were reported. Two high ESP soils in Yinchuan, China were used in the soil amelioration test. The pH and EC values in CFP and WCPs took a higher value than FGDG, and the order of Ca concentration was FGDG > WCP > CFP. In the soil amelioration tests using CFP and WCPs, salt-affected soil decreased drastically in EC and ESP. Moreover, the CFP and WCPs in different particle diameters based on the 1.0 wt% application rate of FGDG were added to the soil. Soil chemical properties before and after mixing with soil amendments were measured, and their properties were evaluated after 3 weeks and 6 weeks. Consequently, soil EC and ESP decreased drastically in all application tests, but soil pH in CFP and WCPs took a high value. And pH, EC, and ESP after 6 weeks took almost the same value immediately after amelioration. WCPs smaller than 2.0 mm could ameliorate a high ESP soil at a lower application rate compared to larger WCPs. In addition, the increase in hydraulic conductivity due to waste concrete application could be confirmed. These results indicated the effectiveness of waste concrete as salt-affected soil amendments.departmental bulletin pape

Pricing around Japanese IPOs
Get PDF日本の株式市場では，1997年に公開価格の決定方法が入札方式からブックビルディング（BB）方式へ変更後は，マザーズなどの新興市場へのIPO銘柄を中心に顕著なアンダープライシング（過小値付け）が見られた。最初に投資家へ提示される想定発行価格がIPOディスカウントなどの影響で低めに設定され，これが初期値として機能するアンカリングが生じている可能性がある。また，機関投資家へのロードショー後に設定される仮条件の上限値で9割以上のIPO銘柄の公開価格が決定される傾向が見られ，上限値を超えて公開価格を決定できないわが国特有のIPO制度の問題点も確認できた。IPO後の中長期的な価格形成については，入札時にはアンダーパフォーマンスが見られたが，BB方式時には，本則市場へのIPO銘柄を中心にむしろオーバーパフォーマンスが見られた。IPO後5年後の累積相対株価水準を基準にして公開価格を逆算したところ，入札時には公開価格が割高であったにもかかわらず投資家の楽観的期待が原因で初値が一層上昇した状況，BB方式時には公開価格が顕著に割安で過小値付けが生じていた状況と整合的な結果が見られた。過小値付けは，資金調達額の目減りという形で発行企業にとって不利に働く。そのため，適正な公開価格を導く意義の再確認を行うとともに，想定発行価格を決定する際のIPOディスカウントの廃止や仮条件の上下限値を超える水準での公開価格決定の解禁などに関する制度改善の必要性については，十分に議論を行うことが望ましい。departmental bulletin pape
