ABSTRACTDigitization and its impact on regions and clusters remains overlooked in the literature, and constitute this present paper’s goal. How does an industrial district transit collectively to the adoption of new radical changes brought about by Industry 4.0? This study explores the role of collective actors and innovation platforms during the early stages of a pilot policy to stimulate a collective transition of an entire MID (Marshallian Industrial District) into Industry 4.0. We posit that institutional isomorphism and the existent social capital in MIDs is a double-sword phenomenon that can also positively constitute an enabler for fostering change on a collective-basis. Technology transitions, such as Industry 4.0, can be supported and led by collective actors that are central in facilitating the adoption of Industry 4.0 in MIDs, enticing innovative firms to engage in that transition, establishing, legitimizing, and embedding a new set of processes, practices and inter-firm arrangements for digitizing and then promoting imitation: the positive leverage of isomorphism. Thus, MID transition is facilitated through capitalizing on the MID logic of cooperation-competition and isomorphism, by developing and promoting a collective understanding of the new paradigm, building a supportive infrastructure, educating in the new technology and avoiding cognitive inertia. 相似文献

ABSTRACTThis paper examines the contribution of microscopic multi-proxy approaches to the study of early husbandry practices and animal diet by integrated micromorphological, phytolith, and calcitic dung spherulite analyses of midden deposits at the three neighbouring Neolithic sites of Boncuklu (9th–8th millennium cal BC), P?narba?? (7th millennium cal BC) and Çatalhöyük (8th–6th millennium cal BC) in the Konya Plain, Central Turkey.The results reveal considerable chronological and contextual variation in human-animal inter-relations in open areas between different communities and sites. At Boncuklu, middens display well-defined areas where phytoliths and substantial accumulations of omnivore faecal matter low in spherulite content have been identified. By contrast, open spaces at the Late Neolithic campsite of P?narba?? comprise large concentrations of herbivore dung material associated with neonatal ovicaprine remains from spring birthing. Here, the deposits represent repeated dung-burning events, and include high concentrations of dung spherulites and phytoliths from wild grasses, and leaves and culms of reeds that, we suggest here, derive from fodder and fuel sources. Late middens at Çatalhöyük are characterised by thick sequences derived from multiple fuel burning events and rich in ashes, charred plants, articulated phytoliths – mainly from the husk of cereals, as well as the leaves and stems of reeds and sedges – and omnivore/ruminant coprolites, the abundance of the latter declining markedly in the latest levels of occupation.The application of this integrated microscopic approach to open areas has contributed to unravelling the complexity of formation processes at these sites, providing new insights into herding practices, diet, and the ecological diversity of Neolithic communities in Central Anatolia. 相似文献

The Radiocarbon Chronology of Southern Spain's Late Prehistory (5600–1000 cal BC): A Comparative Review 下载免费PDF全文

This paper is the first updated review of the scope, depth and problems related to the current radiocarbon chronology of the late prehistory of southern Iberia. The aim is twofold. First, it critically analyses the quantity and quality of radiocarbon dates used to interpret the diverse trajectories of western Mediterranean societies throughout more than four millennia. Secondly, it reviews a set of three different and prominent archaeological phenomena from an inter‐regional comparative perspective: primary and secondary burial practices, domestic stone architecture and ditched enclosures. Our long‐term, geographically wide‐ranging approach locates similarities while highlighting the effects of local and historical conditions in certain divergent circumstances. 相似文献

ABSTRACTThe residents of the Canary Archipelago consumed limpets since the arrival of humans ~2500 yrs. ago, and these harvested gastropods were deposited in large coastal shell middens. This work preliminarily explores shell margin oxygen isotope composition (δ18O) and body size of the black limpet (Patella candei d’Orbigny, 1840) from archaeological sites in the Canary Islands to assess possible seasonal variability and intensity of shellfish collection throughout the late Holocene. The shell margin δ18O values of 100 shells (radiocarbon dated between ~500 and ~1800 cal. yr BP) were analysed to estimate sea surface temperature (SST) at time of death. Paleotemperature estimates suggest shellfish harvesting was not year-round, and was avoided in the cooler months (when SST?<?20°C). This pattern differs from most higher latitude Mesolithic and Neolithic human groups, which gathered shellfish year-round, targeting winter more heavily. Preliminary body-size measurements suggest shell sizes have experienced a decline from aboriginal times to the present, which possibly resulted from increasing anthropogenic pressures. During aboriginal inhabitation, maximum adult shell size remained stable, suggesting that present-day harvesting practices are more intense than harvesting from aboriginal human groups. This intensive collection has likely diminished the average adult size of limpet populations in the islands by ~27%. 相似文献

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art. 相似文献

Hominin presence is well documented in a number of Early Pleistocene and early Middle Pleistocene European localities. However, the evidence currently available indicates that Acheulean handaxes spread in the fluvial basins of Western Europe during MIS 11, ~400 kyr ago, associated with Homo heidelbergensis, although a number of early Middle Pleistocene Acheulean assemblages have been dated from MIS 16 onwards. For this reason, the magnetostratigraphic dating in Southeast Spain of two archaeological localities, the open-air site of Solana del Zamborino (SZ) and the rock-shelter site of Cueva Negra del Estrecho del Quípar (EQ), that put back the appearance of handaxes to the Early-Middle Pleistocene limit (Scott and Gibert, 2009) is of particular interest, as the new ages suggest that H. heidelbergensis was a contemporary of H. antecessor that had the ability to produce Levallois debitage and to control fire during the Early-Middle Pleistocene transition. However, we have detected a number of errors in the interpretation of the archaeological assemblage from the first site as well as striking discrepancies with the original faunal lists published for both localities, with several large mammal species that are omitted or arbitrarily changed to make the assemblages consistent with the new ages deduced from magnetostratigraphy. For this reason, we suggest that: (1) the finding of reverse polarity in the sediments sampled for paleomagnetism in SZ may simply record one of the polarity reversals that took place during the Brunhes Chron, although the use by Scott and Gibert (2009) of a composite stratigraphic column precludes correlating these levels with a specific reversal; and (2) the fauna and tools of EQ correspond to the late Middle Pleistocene sedimentary infillings of this karst site, while the samples taken for paleomagnetism belong to a previous sedimentary cycle during the Matuyama Chron. Such interpretations would be in better agreement with the age estimates provided by biostratigraphy and also with the currently accepted chronology for the appearance of Acheulean industries in Western Europe. 相似文献

This article examines the evolution and transformation of female religious life in Spain under Franco's regime, which began after the Spanish Civil War in 1939 and ended with the dictator's death in 1975. During the dictatorship, the public stance towards Catholicism made consecrated religious life one of the potential social undertakings for women at that time. The Concordat of 1953 corroborated National Catholicism, and women religious abided by a heritage sanctioned by this ideology. The Second Vatican Council parted ways with this tradition, and some women religious reassessed their role as females and consecrated women in their society. This article analyses how the renewal doctrine of the Council was received in Spain, particularly regarding female religious life, revealing the commonalities and differences of opinions and practices resulting from the break with National Catholic schematism, as well as the first manifestations of renewal among women religious. 相似文献
