This paper advances a measure of knowledge complexity to analyse for Ireland whether more complex knowledge is generated by local or foreign firms. Information on assignees, technological structure and global ownership contained within a recently developed Irish patent database forms the basis for distinguishing between technologies developed by local and nonlocal firms. Thereafter, our knowledge complexity index uses a modified bipartite network to link these technologies to their country of origin, i.e. local or nonlocal. Our results indicate that the most complex technologies tend to be produced in a few diverse regions. Furthermore, the majority of complex knowledge is generated in technology classes where the share of foreign activity is greater than local firms.  相似文献

Starting from questions about the nature of cultural diversity, this paper examines the pace and tempo of change and the relative importance of continuity and discontinuity. To unravel the cultural project of the past, we apply chronological modelling of radiocarbon dates within a Bayesian statistical framework, to interrogate the Neolithic cultural sequence in Lower Alsace, in the upper Rhine valley, in broad terms from the later sixth to the end of the fifth millennium cal BC. Detailed formal estimates are provided for the long succession of cultural groups, from the early Neolithic Linear Pottery culture (LBK) to the Bischheim Occidental du Rhin Supérieur (BORS) groups at the end of the Middle Neolithic, using seriation and typology of pottery as the starting point in modelling. The rate of ceramic change, as well as frequent shifts in the nature, location and density of settlements, are documented in detail, down to lifetime and generational timescales. This reveals a Neolithic world in Lower Alsace busy with comings and goings, tinkerings and adjustments, and relocations and realignments. A significant hiatus is identified between the end of the LBK and the start of the Hinkelstein group, in the early part of the fifth millennium cal BC. On the basis of modelling of existing dates for other parts of the Rhineland, this appears to be a wider phenomenon, and possible explanations are discussed; full reoccupation of the landscape is only seen in the Grossgartach phase. Radical shifts are also proposed at the end of the Middle Neolithic.  相似文献

The Western drama High Noon introduces political considerations deeper than the maelstrom of American anticommunism of the 1950s against which it is most often viewed. It presents the central problems of modern political obligation as arising out of an encounter between Aristotelian and Lockean ideas about marriage, friendship, consent and coercion, and religious obligation. The marshal Kane, representing the altered vestige of Aristotelian ideals, desperately seeks help from the Lockean-like community of Hadleyville. The resulting tension lays bare the political ambiguity many find inherent in American political life.  相似文献

The study of settlement patterns must be accompanied by careful evaluation of the processes of formation of the archaeological record and of its recovery. A selective review is offered of Neolithic case studies from central and western Europe, from theLinearbandkeramik culture (fifth millennium bc) to Denmark and Britain (fourth and third millennia bc). The emphasis of the study is upon dispersed settlement patterns. Possibilities of specialization and hierarchy are discussed. Settlement studies should be further exploited for the system, or social rules and contexts, that may be inferred from the patterning of settlements.  相似文献

Perhaps nowhere in European prehistory does the idea of clearly-defined cultural boundaries remain more current than in the initial Neolithic, where the southeast–northwest trend of the spread of farming crosses what is perceived as a sharp divide between the Balkans and central Europe. This corresponds to a distinction between the Vin?a culture package, named for a classic site in Serbia, with its characteristic pottery assemblage and absence of longhouses, and the Linearbandkeramik (LBK), with equally diagnostic but different pottery, and its apparently culturally-diagnostic longhouses, extending in a more northerly belt through central Europe westward to the Dutch coast. In this paper we question the concept of such a clear division through a presentation of new data from the site of Szederkény-Kukorica-d?l?. A large settlement in southeast Transdanubia, Hungary, excavated in advance of road construction, Szederkény is notable for its combination of pottery styles, variously including Vin?a A, Ra?i?te and LBK, and longhouses of a kind otherwise familiar from the LBK world. Formal modelling of its date establishes that the site probably began in the later 54th century cal BC, lasting until the first decades of the 52nd century cal BC. Occupation, featuring longhouses, pits and graves, probably began at the same time in the eastern and western parts of the settlement, starting a decade or two later in the central part; the western part was probably the last to be abandoned. Vin?a pottery is predominantly associated with the eastern and central parts of the site, and Ra?i?te pottery with the west. Formal modelling of the early history of longhouses in the LBK world suggests their emergence in the Formative LBK of Transdanubia c. 5500 cal BC followed by rapid dispersal in the middle of the 54th century cal BC, associated with the ‘earliest’ (älteste) LBK. The adoption of longhouses at Szederkény thus appears to come a few generations after the start of this ‘diaspora’. Rather than explaining the mixture of things, practices and perhaps people at Szederkény with reference to problematic notions such as hybridity, we propose instead a more fluid and varied vocabulary, encompassing combination and amalgamation, relationships and performance in the flow of social life, and networks; this makes greater allowance for diversity and interleaving in a context of rapid change.  相似文献
