La révolution scientifique les révolutions et l'histoire des sciences

In the paper Ernest Coumet presented at the conference on Koyré (Paris, 1986), he suggested that the term «scientific revolution» does not denote for Koyré an historical event, but an idealtype, in Weber's sense. First, the author discusses this thesis and presents the arguments Coumet advances to support it. In the second part of his paper, he criticises the use of the notion of revolution in the history of science. In particular, he argues against the distinction between scientific theories and a «scientific thinking», which would be influencedby the «philosophical thinking» and whose changes would produce a revolution.     

Innovation and Change in the Marshallian Industrial District

One of the relatively neglected aspects of studies of industrial districts is that of processes of innovation and structured change. In the paper, a preliminary theorization is offered, with evidence from a case in Tuscany. The paper concludes that creative capacities embedded at the local level may be valuable in this respect.     

On entrepreneur ship,region and the constitution of scale and scope economies

This paper proposes a framework of analysis in which: (1) the constitution of new sources of economies of scale or scope is supported by systemic entrepreneurship; (2) the realization of such economies by incremental entrepreneurship takes the form of external economies, or alternatively of internal economies, together with the prevalence of different combinations of organizations, technologies and regional characters; and (3) the manifestation in the form of external economies is sustained by market rules and focused public intervention, which complement the working of markets, and which can be embedded in regional (or local) relations. Further and more specific conclusions will be referred to in the case of external economies within production systems which are assuming or are reproducing the techno‐organizational characters of flexible specialization. The standard case of the industrial district with final markets largely characterized by differentiated and variable markets falls within such application.     

“Kontakte” – Reflexionen naturwissenschaftlich‐technischer Innovationsprozesse in der frühen Elektronischen Musik Karlheinz Stockhausens (1952–1960)

“Kontakte” – Reflections of Innovative Processes in Science and Technology in Karlheinz Stockhausen's Early Electronic Music (1952–1960). The following article will give an overview of the interdependence of aesthetic and scientific/technical developments in German composer Karlheinz Stockhausen's early works of electronic music. It is an outline of the major steps in his artistic evolution between the works “Etude (Musique concrète)” and “Kontakte”, their relation to innovations in psychoacoustic and sound‐studio technology as well as the impact, that the works from that period had on the fundamental changes in musical aesthetics during the course of the 20th century.     

Visual images in Luigi Galvani's path to animal electricity

The scientific endeavor that led Luigi Galvani to his hypothesis of "animal electricity," i.e., of an electricity present in a condition of disequilibrium between the interior and the exterior of excitable animal fibers, is reviewed here with particular emphasis to the role played by visual images in Galvani's path of discovery. In 1791 Galvani formulated his model of neuromuscular physiology on the base of the image of a muscle and a nerve fiber together as in a "minute animal Leyden jar." This was the last instance of a series of physical models that accompanied Galvani's experimental efforts in the search of a theory capable of accounting for the electric nature of nerve conduction in spite of the many objections formulated in the eighteenth century against a possible role of electricity in animal physiology.     

The Secrets of a long life: The Dutch firm of covens & mortier (1685–1866) and their copper plates

Abstract

Commercial map publishing firms between the mid‐sixteenth and mid‐nineteenth centuries needed to prolong the life of their copper plates for as long as possible. In order to avoid the costs of engraving new plates, the famous Dutch publishing house of Covens & Mortier of Amsterdam (1685–1866) amended existing plates for topographical and politico‐administrative changes, engraving errors, imprint alterations and marks resulting from general wear. Not only were the plates altered, but the printed maps themselves were sometimes also modified: a new title cartouche might be pasted on or a date or part of the text scratched away. In these ways the map publishing firm was a master of creative solutions as regards both the re‐use of old copper plates and the ‘renewal’ of old printed maps.     

The Festival of St John: Norm and Change in Civitella Roveto in Abruzzo (Italy)

This essay describes the festival of Saint John (24 June) at Civitella Roveto in the province of Aquila, Italy. The ritual is analysed as it was at the beginning of the twentieth century and in its contemporary form, in order to reconstruct the norm of the festival and thereby to show the main transformations of the event, and its shifting social context. In addition, the research highlights the connection between the festival and the ritual cycle, investigated in terms of its interaction with the productive cycle of the community and with the cosmic cycle. Finally, the new social and symbolic meanings assumed by the figure of St John and his festival are brought to light.     

Sasanian glass from Veh Ardašīr: new evidences by ICP-MS analysis

Forty-seven glass fragments excavated at Veh Ardašīr, in central Iraq, were analysed by ICP-MS, determining 38 chemical elements; the samples represented finished objects as well as waste and raw glass. The obtained data point to the use of sodic plant ash for the production of glass in the entire Sasanian period (third–seventh century AD), strengthening previous results from another set of fragments from the same site. Magnesium and phosphorus contents give further evidence of the possible use of different kinds of plant ash, while trace element levels and some element correlations suggest the recourse to different silica sources. As a whole, the obtained results allow one to recognize three main glass compositions, related to the use of different silica sources combined with different kinds of plant ash. The occurrence of waste and raw glass in all groups of composition confirms that at least glass working took place in Veh Ardašīr.
