格差や貧困の拡大と,気候危機を背景として,2018年以降,欧米では反緊縮グリーン・ニューディール(GND)が相次いで提案されている.GNDは,環境政策と経済政策を統合させた急進的な政策案である.気候変動防止のために従来提案されていたよりも,早急に炭素排出ゼロ社会への移行を実現するために,巨額の投資の実施を求めるとともに,雇用の「公正な移行」の実現と,富や人種,ジェンダー,世代などに関わる不正義の解消にも注意を払っている.また反緊縮の経済理論に基づき,資金は主に増税によってではなく,年金基金等の巨額の民間資金の誘導と,(通貨発行権を有する国々の場合は)赤字支出でまかなうことを求めている.

In April, 1997, construction of a dike in the inner part of Ariake Sound to close off the innermost area of Isahaya Bay was completed. In June of both 1991 and 2002, benthic surveys were conducted using a Smith-McIntyre grab sampler at 88 stations over the entire sublittoral area of Ariake Sound. The structure of the gammaridean amphipod assemblage was compared between 1997 and 2002 with regard to any change in grain-size composition of the substrates and dissolved oxygen concentration of the bottom waters. No noticeable changes were observed in the distribution of the median particle diameter and silt-clay content, nor in the spatial arrangement of the sediment types of the substrates. Hypoxic water masses were observed in the bottom waters in 1997 in and around Isahaya Bay and in the southern part of Ariake Sound. Other studies also recorded hypoxic water masses in the former area in 1999 and 2001. For the amphipod assemblage, a total of 12, 434 individuals of 94 species belonging to 24 families was collected in 1997; the most dominant species was Photis longicaudata (family Isaeidae). In 2002, those values had changed to 37, 649 individuals, 89 species, and 27 families, with the most dominant species being Corophium sp. A (family Corophiidae). In both years, the amphipod assemblage was dominated by six families, including Isaeidae, Ampeliscidae, Corophiidae, Priscomilitaridae, Melitidae, and Aoridae, although the dominance order changed partially. The amphipod assemblage in both years inclusive was divided into eight groups using group-averaged clustering and non-metric multidimensional scaling. The group with the highest number of stations occupied the largest bottom area, composed of poorly-sorted medium to coarse sand along the longitudinal axis of Ariake Sound; the number of stations in this group increased from 41 in 1997 to 57 in 2002. Increase in individual density and expansion of distribution range of seven species of the superfamily Corophioidea (Corophiidae, Isaeidae, Priscomilitaridae), which occurred around the two hypoxic areas, contributed most to the range extension. For the above-mentioned six most dominant families, density of individuals and proportional composition of number of individuals in each of the two hypoxic areas and other, non-hypoxic areas were compared between the two years. In particular, both values remarkably increased for several members of the Corophiidae, including Corophium sp. A and C. crassicorne, in 2002; the exception was the value for density of individuals in the southern hypoxic area. The Shannon-Wiener species diversity index values were lower in 2002 for both the two hypoxic areas and the combined non-hypoxic areas, and for the three main groups of the amphipod assemblage.

This paper critically deals with an Analytical Marxian Professor Yoshihara's two critiques against the Fundamental Marxian Theorem. One is the possibility of positive profit without positive exploitation, under the condition of joint production and laborer's consumption choice. The other is so-called Generalized Commodity Exploitation Theorem, which claims value and exploitaion concept can be defined for all commodities not only for labor and thus positive profit is identical with exploitation of any commodity not only of labor. I shall show the former demonstration is wrong because it needs negative net production. If we limit net production to be non-negative and permit disposal, then the exploitation of his case turns to be positive. To answer the latter critique, we shall examine the dual system of the value equations and their corresponding optimization problem or utility function. Then we can confirm that if we define net production as the commodities disposable for human being or if we define utility function as that of human being, then the value concept consistent with the presupposition must be labor value and exploitaion concept must be that of labor.

Okishio's way to deal with labour value concept was to separate it from price concept. It is consistent with Marx's fundamental dual view of the reification theory that the nature of the human society in general, which is the mutual labour interdependence among persons, does not appear directly but appears taking the form of the exchange relationship among commodities. The latter, where the price categories hold, alienates from the former, where the bestowed labour(the substance of the value)hold as a key category to grasp the reproduction. It is the existence of gap between price and labour value that this view emphasizes to criticize this structure, rather than the price reflection of labour value. First in the present paper, the alleged compatibility of two "total identity propositions" proposed by the Single System Approach is criticized. It is shown that their value of the labour power is the labour to produce the similar contraction of the net production bundle, which contains commodities workers never buy. And the compatibility of the two total identity propositions holds between any two evaluation vectors, besides labour value and production price. And Marx-Okishio's dual structure of the theory is confirmed. The Hawkins-Simon condition of I-A, where A is the input coefficient matrix, means net production is possible as well as labour value is definable(labour is alocatable). Whereas the Hawkins-Simon condition of I-A_+, where A_+ is the extended input coefficient matrix adding labour force sector to A, means surplus production is possible as well as positive profit exists. The former condition indicates the productiveness of personal interdependence nature of society. The latter condition indicates the productiveness of capitalistic reification form of society. Okishio's Fundamental Marxian Theorem, which states equivalence between positive profit and exploitation of labour, observes profit phenomenon holding at reification world as a fare equivalence of trades, from the stand point of the human interdependence world and then there finds exploitation relationship between humans. So called Generalized Commodity Exploitation Theorem uses bestowed commodity concept other than bestowed labour and finds that exploitation of any commodity is equivalent with positive profit. But we realize that the existence of a positive bestowed commodity vector is identical with some kind of Hawkins-Simon condition. And it is shown that the condition means productiveness for a special "net production" concept, which includes inputs to produce the commodity but does not include workers' consumption. We can interpret a commodity exploitation concept as an interpretation of profit from a stand point on a special understanding of essence of society that grasp society as interdependence relation between the commodity. Labour value concept has been developed from the primitive definition by simultaneous equations to Morishima's labour minimization definition and then to my Minimum Labour with Equal Utility definition. The present paper traces this direction of development, which goes further leaving price concept, and shows my study plan that describe non-profit=non-exploitation state as a normative state for workers' class, which functions as a criterion for the criticism free from the reification. In this state, the bestowed labour concept works as a standard to organize he balanced allocation in the personal inter-dependence world. Then, the relation between this criterion and Roemer's criterion, which considers equal distribution of means of production as normative, is examined. In the short run, under the constraint of endowment of means of production, the means of production claim net products even by the social planning without reification. Thus the equal distribution of the means of production is regarded as normative. In(View PDF for the rest of the abstract.)

According to the rapid progress in the performance of the microprocessors and their cost-down, the Engineering Work Station (EWS) and Personal Computer (PC) have been applied to the various problems in the computational mechanics. The finite element method (FEM) is the relatively popular technique of computational analyses among various numerical methods which are aided by the EWS and the PC. The FEM will require the preprocessing to discretize the analyzed domain into triangles. In the paper, we shall present the development of highly interactive and portable pre-processors for 2-D FEM analysis. The present system works on X Window System Version 11 Release 5 (X11R5) on EWSs. Since that tool makes the best use of Graphical User Interface (GUI), even a novice user can make the mesh data and visualize the calculated results readily. The high portability of this GUI is ensured because we adopted the licensefree Athena Widget set as the fundamental GUI gadgets.

産業連関表を用いたコンベンションの経済波及効果の推計には,公共建設の経済波及効果推計などとは異なる固有の困難がある。「買い物」の支出を,商業マージン部分と原価部分に案分して,それぞれ商業部門と当該製造業部門への最終需要としなければならないこと,最終需要を移輸入の含まれるものとそうでないものに分けなければならないことなどである。本稿では,筆者がこれまで行った久留米地域での七つの事例をとりあげ,福岡県産業連関表の34部門表を用いて,経済波及効果推計の手順を詳述する。
