In a world where large urban agglomerations are increasingly regarded by scholars and policy-makers alike as the engines of economic development, the options at the disposal of intermediate and peripheral areas are dwindling. Doing nothing is, according to the dominating theories, likely to result in a steady decline which may jeopardize their very economic viability. Adopting active measures is thus the way forward. In this paper, we argue that the main solution being proposed—interactive learning through the promotion of local agglomeration (buzz option)—may yield limited results, if at all, as it would stifle the circulation of new knowledge and lead to lock-in. By contrast, promoting interaction outside the comfort zone of geographical, cognitive, social and institutional proximity (pipeline option) is more likely to succeed in generating interactive learning and in facilitating the generation, diffusion and absorption of innovation. We illustrate this point by resorting to the case of firm innovation in Norwegian city regions.  相似文献

This work focuses on petro-chemical characterisation of the volcanic inclusions often found within the fabric of many ceramic remains from various archaeological sites in eastern Sicily. Petrographic observations and EMP analyses revealed that volcanic glass is strongly influenced by chemical modifications during the firing process, whereas clinopyroxenes keep their original composition unaltered thus constituting an effective tool for provenance attributions. Multivariate statistical analysis of the latter can in fact unambiguously discriminate between different productive areas by comparisons with pyroxenes from volcanics belonging to distinct magmatic provinces. The method proposed here was tested on ceramic remains of different ages and typologies found in southern Italy.  相似文献

Consilience of genetics and archaeobotany in the entangled history of rice   总被引:3,自引:0,他引:3  
Major leaps forward in understanding rice both in genetics and archaeology have taken place in the past decade or so—with the publication of full draft genomes for indica and japonica rice, on the one hand, and with the spread of systematic flotation and increased recovery of archaeological spikelet bases and other rice remains on early sites in China, India and Southeast Asia. This paper will sketch a framework that coherently integrates the evidence from these burgeoning fields. This framework implies a reticulate framework in the phylogeny of early cultivated rice, with multiple starts of cultivation (two is perhaps not enough) but with the key consolidations of adaptations that must have been spread through hybridisation and therefore long-distance cultural contacts. Archaeobotanical evidence allows us to document the gradual evolutionary process of domestication through rice spikelet bases and grain size change. Separate trends in grain size change can be identified in India and China. The earliest centre of rice domestication was in the Yangtze basin of China, but a largely separate trajectory into rice cultivation can be traced in the Ganges plains of India. Intriguingly, contact-induced hybridisation is indicated for the early development of indica in northern India, ca. 2000 BC. An updated synthesis of the interwoven patterns of the spread of various rice varieties throughout Asia and to Madagascar can be suggested in which rice reached most of its historical range of important cultivation by the Iron Age.  相似文献

The use of tooth mark sizes to infer carnivore types when analyzing the modification of faunal assemblages has been criticized on the base of intense overlap in tooth mark size among differently sized carnivores. The present study analyzes this overlap and presents some critical explanations for it. This work is based on the largest collection of tooth pit dimensional data collected to date for some of the most relevant carnivore types. The study empirically shows that small and large carnivores can be clearly differentiated when using tooth pit size, with a higher discrimination when using tooth marks on dense shafts than on cancellous ends. It is argued that most previous studies of tooth mark sizes have reproduced a higher overlap probably because sample sizes were small, and experiments were carried out using small carcasses (which require a smaller bite force) or for a combination of factors.  相似文献

This paper proposes the insertion of cartographic production about the Portuguese possessions into a wider context of interests and need for information experienced by the Hapsburgs during the Iberian Union (1580–1640). I focus on two documents, compiled as a result of two requests made by the monarchs who wished to learn about their domains in India and Brazil: the 1612 Livro que dá razão do Estado do Brasil, written by Captain Diogo Campos Moreno, with maps by João Teixeira Albernaz I, and the Livro das Plantas de todas as fortalezas, cidades e povoações do Estado da Índia oriental, dated 1635, by the official chronicler of the Estado da India, Antonio Bocarro, with city views usually attributed to Pedro Barreto de Resende.

These texts and maps show a shift of interests from India to Brazil. They incorporate the various aspects that the authors considered relevant, interesting or representative of the Portuguese presence in these spaces. At the same time, the royal orders that gave rise to these surveys bring some elements that give specificity to each region, but emphasize the effort to standardize the information and to ensure a common administration over different areas of the empire.  相似文献

This paper investigates the different roles played by universities and technology institutes (TIs) as innovation partners of firms. Comparing the characteristics of Spanish firms collaborating with these agents allows us to better define complementarities among the target groups of these organizations. Our findings show that those firms collaborating with universities are bigger, have higher internal capabilities and are less dependent on their external relationships while firms collaborating with TIs are smaller, have weaker internal capabilities but are more open to their environment and thus more reliant on external sources. We point to the implications of these findings for regional development. Universities have a role as partners of more technologically advanced firms. TIs, on the other hand, partner those firms, which though also quite advanced, require more external help in their innovation processes. These results should help policy-makers in the definition of more complex regional strategies and the provision of tools aimed at different goals. Managers of universities, TIs and client firms should find these results of help in developing more positive collaborations with one another.  相似文献

This article examines the ideational dimension of federalism and its consequences for the analysis of policy development. With this objective in mind, the article offers an explanation for Canada's rejection of the two main aspects of the ‘Australian model’ of equalisation: the assessment of expenditure needs and the existence of an arms-length commission to determine payments. As argued, the ideological prevalence of provincial autonomy in Canada explains why federal officials opted to reject the ‘Australian model’ as they prepared to establish the country's program and why subsequent reforms never introduced a needs-assessment dimension or created an arms-length agency to administer equalisation. At the theoretical level, this article shows how ideational factors can shape policy outcomes.  相似文献
