The evolution of Lombardy's economic structure and international position led the regional government to build up a network of public and private stakeholders in the effort of promoting the creation of new knowledge and supporting innovation at local level. In this article a technology picture of the region and the main policy actions undertaken in recent years in Lombardy to promote a nest of linkages within actors, moving along the approach of regional innovation systems are presented.  相似文献

In this paper I examine the development of a particular kind of grey stoneware called kamuiyaki which was produced and traded within the Ryukyu Islands, southwestern Japan, in the eleventh to fourteenth centuries. The wares themselves, their chronology, and archaeological context are discussed. The kilns represent the first enterprise in the islands in which a commodity was made for exchange on a substantial scale. The establishment of the kilns in a remote area, with technological borrowing from both Japan and Korea, reflects social and economic trends of the beginning of the Medieval Period in Japan. Greyware production, circulation, and consumption, reconstructed from recent excavations, shows a political economy capable of fostering the development of small states on the island of Okinawa in the thirteenth and fourteenth centuries.  相似文献

Ethnoarchaeology appears nowadays as a poorly formulated field. However, it could become a real science of reference for interpreting the past if it was focused upon well-founded cross-cultural correlates, linking material culture with static and dynamic phenomena. For this purpose, such correlates have to be studied in terms of explanatory mechanisms. Cross-cultural correlates correspond to those regularities where explanatory mechanisms invoke universals. These universals can be studied by reference to the theories found in the different disciplines they relate to and which are situated outside of the domain of archaeology. In the domain of technology, cross-cultural correlates cover a wide range of static and dynamic phenomena. They allow the archaeologist to interpret archaeological facts—for which there is not necessarily analogue—in terms of local historical scenario as well as cultural evolution. In this respect, it is shown that ethnoarchaeology, when following appropriate methodologies and focussing on the universals that underlie the diversity of archaeological facts, does provide the reference data needed to climb up in the pyramid of inferences that make up our interpretative constructs.  相似文献

Level IV of Molodova I, an open-air Middle Paleolithic site in the Ukraine has been described by some researchers as a possible source of evidence for early symbolic behavior. We examined bone objects from this layer that were identified by Ukrainian researchers as exhibiting possible Neandertal produced engravings including two anthropomorphic figures. While we have determined that there is no evidence of symbolic activity at Molodova I, the database we have created, with its systematic recording of traces left by taphonomic agents on faunal remains, provides a better understanding of the overall site taphonomy.  相似文献

In the 18th century, medical practice was essentially based on communication. Cranial trepanation, however, was usually performed on an unconscious person. Here the dialogue ceased. It was the only operation which had to be attempted without the positive consent of the patient. Thus trepanation challenged the surgeon's skill not only with its intricate surgical practice, but also with its unusual social setting. The present paper illustrates possible ways out of the "trap of trepanation" by interweaving two points of view. On the one hand, a general account is given on the basis of surgical publications written by Lorenz Heister and his contemporaries. On the other, the unpublished sources of the Heister correspondence serve to reconstruct the case of Heinrich Wilhelm Bachmann, a German merchant who fell victim to a traffic accident and underwent trepanation in 1753. The case study shows how the physician in charge counterbalanced the patient's inability to communicate by strengthening the remaining network of professionals, and ultimately confirming his decisions by use of the post-mortem.  相似文献

Abstract

The sustainable development model has largely failed to address the social and environmental challenges of the 21st century. True sustainability will only occur when it is valued as a part of the taken-for-granted daily life of individuals and cultures across the globe. This has not yet happened because humanity has not evolved a global consciousness quickly enough to match the global advances in telecommunications and transportation technologies that have created a socially and economically ever-shrinking planet. Travel and tourism contributes to the expansion of global consciousness, although only in a haphazard and unintentional manner. The COVID-19 pandemic is a result of planetary time-space compression and is forcing an expansion in human consciousness that will make humankind better able to address global problems. There will still be considerable diversity on the planet, as now, but the pandemic will stimulate growing numbers of people, businesses and governments to adopt new ways of thinking, behaving and operating that are more closely aligned with the goals of sustainable development. This could be further enhanced if travel and tourism were to adopt the expansion and awakening of global conscious as a fundamental and transformational value in the products and experiences that it offers.  相似文献
