The eruptive sequence of the An-ei eruption of Sakurajima volcano (1779-1782) is revealed by historical records. From the evening of November 7, 1779 (the 29th day of the 9th month in the 8th year of An-ei), Kagoshima and its environs were shaken frequently. At 11 a.m. of the next day, the water in the wells in the island boiled up, spouting at several points and the color of sea became purple. On the noon of the same day, minor white plumes rose up from the Minamidake summit crater. At about 2 p.m., plinian eruption oecurred at the southern upper slope of Minamidake, and several tens of minutes later, at the northeastern flank of Kitadake. The height of eruption column reached about 12000 meters. It is estimated that a pyroclastic flow was generated at 5 p.m. The plinian eruption climaxed from the evening of November 8, to the morning of next day, and later was followed by emission of lava flows. The activity of the southern craters ceased within a few days, but lava emission from northeastern craters lasted for a long period. On November 11, the lava flow from northeastern craters entered into the sea. Since then, submarine explosions occurred repeatedly off the northeastern coast, and it continued to January 18, 1782. Nine small islands produced by this submarine volcanic activity during a year. Submarine explosions caused small tsunamis on August 6 and 15, September 9, October 3 1, November 9, 1780 and April 11, 1781.

This paper uses individual-level data to examine the cause of the sudden decline in turnout in House of Representatives elections in the 1990s.The turnout rate remained flat from 1972 to 1990, but between 1990 and 1996 fell rapidly. In fact, individual-level data show that the electorate's political awareness changed markedly.The analysis utilized in this inquiry first offers a comprehensive explanation for the sudden change in turnout. It then establishes determinants of both voting and abstention through probit analysis, and finally illustrates the cause of the fall in turnout through simulations.The results show that the decline in turnout from 1990 to 1996 was due not to a decrease in mobilization, but rather to a decline in partisanship and low political interest of the electorate. In addition, alteration of the electoral rules had little significant effects.

In recent years, modern radical leaders have been elected in some representative metropolitan municipalities in Japan, such as Tokyo, Osaka, Yokohama, and Nagoya. This article studies a case of Nagoya city, and analyses radical reformist mayor's electoral base. As a result of analysis of survey data, we obtain some empirical findings. (1) The effect of basic social categories is not so strong, but young voters tend to approve Kawamura's job. (2) Not only supporters of Democratic Party, but also active non-partisans approve Kawamura's job, and voters' reformist identity is also significant for job approval. (3) Political organization members and government sector workers don't approve Kawamura's job. In modern Japanese cities, the system has weakened which enables parties to get voters' support through various groups and organizations. A large number of urban voters often demand political reform. This article shows the social base of today's urban political antagonism.

This essay examines contemporary arguments for basic income in view of Marxian theories of political economy. In the first section, it begins with a general definition of basic income as a regular income publicly supplied to all individual social members without means test. This idea has gathered academic and social attention in Western Europe since the 1980s. It reflected a deadlock of traditional welfare policies, as individualistic life style (such as single mothers and elderly singles) became widespread, as well as increasing irregular workers with unstable jobs. It has been supported not just by social democrats among other various ideologists but also by influential Marxian theorists as a policy device possibly to guarantee real freedom for all in a future society via social democracy against the Soviet model. When the idea is introduced into Japan after two decades, however, it is argued mainly within a framework of reformation of the existing social security system in a capitalist society. The possible academic contributions from the view of Japanese Marxian political economy to this contemporary issue still remain to be explored. In the second section, a history of this idea is briefly reviewed. Two types of social thoughts which flowed into the contemporary arguments for basic income are discernible. The first type originates from T. Pain, asserting social need and legitimacy of basic income redistribution upon the premise of capitalist market economy. The second type assumes either centrally planned or market socialist society where some sorts of basic income for social members as communal owners of means of production are easily and duly to be realized. However, full basic income, which is sufficient to maintain an ordinary economic life for individual persons by itself, would not be realizable theoretically even in models of market socialism, not to mention capitalist societies, so long as it would seriously damage functions of labour market and incentive for market labour. In the third section, affinities between ideas of basic income and Marxian political economy are investigated. For instance, Marx's own image of future society beyond capitalism as 'association of free individuals' is clearly closer to the contemporary socialist idea of basic income to achieve real freedom for all individuals rather than to the Soviet model of society. Marxian analysis of contemporary capitalism must serve to clarify the historical necessity and feasibility of basic income as an advanced form of social welfare policy, better and deeper than any other economic schools. On the other hand, contemporary arguments for basic income request reconsideration on some of Marxian thoughts and theories. For example, although Marx formulated that an ideal rule of redistribution 'from each according to one's ability, to each according to his need' is realizable only at the second higher phase of communist society, contemporary Marxian economists began to be aware that redistribution according to one's necessity could be at least gradually and partially realizable already in the form of advanced social security system or its reform program as basic income. Further, if Marx's theoretical treatment of skilled or complex labour is reconsidered as suggested in this essay, Marxian labour theory of value would easily gain affinity with the idea of basic income demanding fundamentally egalitarian redistribution of income. Thus this essay attempts to show that Marxian basic theories of value, surplus-value and economic crisis can serve well as a basic frame of reference also for examining the historical significance of contemporary arguments on basic income.

本稿ではコーホート比較を通じて,未婚化が進行する中での夫婦の学歴に基づく階層結合の趨勢とその変化の要因を検討する.階層結合は開放性指標として検討されてきたが,既存研究は増加する未婚者を考慮に入れてこなかった.そこで本稿では未婚化を考慮に入れた上で日本社会における階層結合の趨勢を検討する.SSM2015年調査データを用いた生存分析から以下の結果を得た.第一に,未婚化はどの学歴にも浸透しているが,近年のコーホートでは四大卒層の40歳時点未婚率の高まりが確認される.第二に,結婚のハザード率を相手学歴別に分解した結果,未婚化と並行して階層結合パターンも相対的に変化している.四大卒女性に関しては,女性の高学歴化にともない高学歴男性の供給量が相対的に低下しており,学歴下降婚が増加している.中学・高校および短大・高専・専門学校卒の女性では大卒男性との結婚が減少し,短大・高専・専門学校卒の男性との結婚が増加しているが,中学・高校卒の男性との結婚は増加していない.以上より,男性稼ぎ主モデルの維持と雇用の不安定化が生じた結果として,晩婚・非婚化が進行しながら,低学歴・高学歴女性における学歴結合が減少している点が示唆される.

「ヨウ素デンプン反応の発色のしくみ」は長い間の謎であった。この謎を解くには,分光法と電子論的解析が欠かせない。すなわち,「なぜ青く呈色するか?」は裏を返せば,「なぜ赤い光を吸収するか?」の電子論的選択則の解明が必須である。「ヨウ素デンプン反応」の主要因はデンプンの直鎖状成分であるアミロースであり,この「アミロース・ヨウ素錯体」に対する物理化学的特性を究明した結果,「錯体の色は,左巻きアミロースらせん糖類中のピラノース環およびグルコシド結合酸素とヨウ素の間での電荷移動およびCH-π相互作用に由来して,結合ヨウ素種I_3^-,I_2各々が折れ曲がり/ねじれ(bent/torque)構造を取り,全体として左巻き配列を取りながらアミロースに内包された発色ヨウ素種I_3^-dimer(I_6^<2->)およびI_3^-・I_2(I_5^-)の励起子間相互作用(exciton-coupling)に起因する」と結論された。口絵11ページ参照。2
