Three projects on the theories of machines are presented: “mecanology” of the architect Jacques Laffite (1932) inspired by biological evolution; “mecanical analysis ” of Louis Couffignal, a specialist in computing machines (1938), which pre figures functional analysis, and the algebraic theory of machines by the mathematician Jacques Riguet (beginning of the 1950’s). During those years, the three men are members of the Circle of Cybernetic Studies. The article focuses on the dialogue between projects, the axes of unification and divergence, and the styles, strategies and postulates of these three candidates, for generalization converging toward the reference constituted by cybernetics. 相似文献

Cattle festivals and cattle rites are much neglected elements of the Indian cattle complex. This study examines Gopashtami and Govardhan Puja, two cattle festivals identified with the cult of Krishna. Although Krishna assumes several aspects in Hinduism, the pastoral Krishna is one of the most popular forms of the deity. Gopashtami and Govardhan Puja are important festivals in Braj, the traditional homeland of the cowherd god. Their origins can be traced to medieval Hindu texts, but Govardhan Puja contains ritual elements that suggest ancient rites have been absorbed into a later Hindu festival. Gopashtami and Govardhan Puja, like any religious festival, can be interpreted at several different levels. They have symbolic meaning, raising questions of conflicting religious traditions or economic systems in the past. They mirror regional patterns of culture and historical tradition in India. They assume a range of social functions, and in addition, form part of the process by which people are exposed to their cultural heritage. Above all, however, they are festivals dedicated to cattle and to the cowherd god Krishna. The myths and rituals of Gopashtami and Govardhan Puja reflect the strong historical ties between Krishna and the cow, as well as reinforce traditional Hindu concepts concerning the sanctity of the cow. 相似文献

Abstract The purpose of this commentary is to explore the sources of decision-making by President Obama. Specifically, the article notes his strong foundation in legal education, law journal editing, and early occupational activities related to law practice. It is observed that a legalist cast of mind rather than broad statements about race, class, and nation define the Obama early period in office. These considerations are often at the center of presidential options chosen, especially in areas of foreign policy and global challenges. The article claims that “legalism” serves to place serious limits on initiatives and independent actions, but also serves to put a brake on tendencies to impose a new imperial presidency. Such ideological checks and balances show unique dimensions to this president, but also continuity with past limits to extremism. 相似文献

In input-output analysis there are two alternate possibilities between Leontief's mechanism (fixed technical coefficients) and Ghosh's mechanism (fixed allocation coefficients). Testing the long-term consistency of these mechanisms entails comparing input-output matrices over time. This paper challenges the value of proportional filters (separate comparisons of column and row coefficients) and introduces the biproportional filter that allows simultaneous comparison of column and rows. An application is proposed using French input-output tables for 1980 and 1993. The stability of column coefficients cannot be taken for granted and, generally, for any sector, both row and column coefficients are found to change simultaneously. 相似文献
