A study by thermal treatment and X-ray powder diffraction on burnt fragmented bones from tombs II,IV and IX belonging to the hypogeic necropolis of “Sa Figu” near Ittiri,Sassari (Sardinia,Italy)

In the course of an anthropological investigation of three tombs of the hypogeic necropolis of “Sa Figu” (near the village of Ittiri in North Sardinia, Italy), numerous burnt bone fragments were collected. In particular, from the whole necropolis we selected a tenth of long bones from tomb IV, a small fragment of femur from tomb II and four fragments belonging to tomb IX. The aim of this work is to determine a temperature range to which the bone fragments were heated, in order to assess a funerary cremation which was presumably used at that time to quickly and hygienically eliminate the flashy parts of deceased people rather than a purification rite with fires inside the sepulchres. We attempted to evaluate the range of temperature to which the bones were likely subjected, making a joint use of thermal treatment and powder X-ray diffraction investigations. From our X-ray line broadening results carried out with a modern approach (Rietveld method), it emerged that a group of five fragmented burnt bones (one specimen belonging to tomb IV, the other four from tomb IX) were subjected to a heat treatment in a temperature range from 600 and 750 °C. Conversely another group of bones (belonging to tombs II and IV) turned out to be subjected to temperatures not higher than 250 °C.     

Paths of an Evolving City: Alternatives and Relevance in Local Policy

This paper builds on some previous results concerning: (1) a view of the industrial district as a learning region, and (2) a typology of features of local development and industrial policies. The aim here is to apply these results to a 'non-district' case study, that is the understanding of the inner logic of the economy and the framing of the local economic policy in an Italian dynamic city (Florence, and its urban system). The interest of such case is two-fold. Firstly, we see how the conceptual framework developed for the analysis of industrial districts can be applied, at least partially, to different types of local systems, and in particular to the important case of complex and dynamic urban systems. Secondly, the complexity itself makes easier, or not avoidable, the consideration of a trade-off in the inputs of local policy's relevance.     

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.

A history of NASA remote sensing contributions to archaeology

During its long history of developing and deploying remote sensing instruments, NASA has provided scientific data that have benefitted a variety of scientific applications among them archaeology. Multispectral and hyperspectral instruments mounted on orbiting and sub-orbital platforms have provided new and important information for the discovery, delineation and analysis of archaeological sites worldwide. Since the early 1970s, several of the ten NASA centers have collaborated with archaeologists to refine and validate the use of active and passive remote sensing for archaeological use. The Stennis Space Center (SSC), located in Mississippi USA has been the NASA leader in archaeological research. Together with colleagues from Goddard Space Flight Center (GSFC), Marshall Space Flight Center (MSFC), and the Jet Propulsion Laboratory (JPL), SSC scientists have provided the archaeological community with useful images and sophisticated processing that have pushed the technological frontiers of archaeological research and applications. Successful projects include identifying prehistoric roads in Chaco canyon, identifying sites from the Lewis and Clark Corps of Discovery exploration, and assessing prehistoric settlement patterns in southeast Louisiana. The Scientific Data Purchase (SDP) stimulated commercial companies to collect archaeological data. At present, NASA formally solicits “space archaeology” proposals through its Earth Science Directorate and continues to assist archaeologists and cultural resource managers in doing their work more efficiently and effectively. This paper focuses on passive remote sensing and does not consider the significant contributions made by NASA active sensors. Hyperspectral data offers new opportunities for future archaeological discoveries.
