ABSTRACT We provide a Bayesian spatial Markov Chain Monte Carlo model composition (MC3) analysis of growth rates in European regional patenting activity. Based on theoretical models on innovation and growth, we identify a large set of candidate explanatory variables that characterize regional stocks of knowledge, including: human resources devoted to innovative activity, scientific and technical capabilities, public and private investments, government policies, as well as regional industry structure, and indicators of regional technology gaps that reflect distance from the technological frontier. Our analysis shows that accommodating spatial dependence and heterogeneity leads to different conclusions regarding factors important for technological transfer and knowledge spillovers.  相似文献

Abstract

Over the past three centuries Italy has been the focus of numerous studies by French historians, who have taken advantage of the great wealth of sources available there. While no new synthesis has yet been achieved, we can identify certain main lines of development in French historiography. In the late 1970s and into the 1980s international relations and, especially, the relations between France and Italy were given the greatest attention, before a new focus on forms of sociability and political pedagogy began to be more common. However, the shifting of focus of historical studies to the centres of political decision making often coincided with less attention being paid to social stratification. Beyond these major themes, some researchers have reconstructed ‘global’ historical models, which have been characteristic of the renewal of post‐war French historiography.  相似文献

That people value ‘people’ over ‘things’ is argued often by anthropologists, but how people value specific forms and qualities of relations as they do in the example of bridewealth is less so. I explore the perspective of Papua New Guinean-born fathers in Australia as they advocate innovations in bridewealth traditions and thereby enable daughters to marry for love, cultivate a companionate marriage, and create a Papua New Guinean household. Past generations gauged the worth of traditional bridewealth by the quantity and distribution of items given and the number of exogamous clan connections forged as an index of past and future relations between clans. The current generation judges the value of even alternate forms of bridewealth for making new possibilities for those who share in it. If bridewealth enables the transnational household to emerge as the unit of decision making that replaces the clan, then innovations in bridewealth support, rather than undermine, a new normativity of companionate marriage that empowers that much wider net of kin. Drawing on a theory of value as the importance of social action towards the goal of the new normativity of the transnational household, I show how choosing a spouse is cultivated by women's fathers who refuse bridewealth, as often as it is by their husbands who provide new forms of wealth at marriage.  相似文献

The specialization of city-centres towards more advanced service activities has mostly been studied in the largest city-regions, the case of smaller urban centres being less well documented. In that context, the objective of this article is to analyse the role of sectoral and regional factors in employment growth in Luxembourg between 1994 and 2005. Using statistical data from the Luxembourg General Inspection of Social Security, this contribution distinguishes 12 categories of manufacturing industries and services according to an OECD-Eurostat knowledge-based classification. Five intra-regional areas are distinguished based on morphological and functional criteria in the Luxembourg Metropolitan Area. Using several indexes, this article first analyses the sectoral specialization and geographical concentration of employment. A model of intra-regional employment growth, initially developed by Marimon and Zilibotti and applied at the European level, is then shown to account for 40 per cent of employment growth. An estimation of the contributions of sectoral and geographical factors highlights the primacy of the latter over the former. Finally, the construction of virtual economies confirms the City's overall lower performance as compared to its close periphery. Results underscore a process of functional integration in the Luxembourg metropolitan area: as the core of the city undergoes a specialization process, the urban area benefits from a relocation of activities less sensitive to distance and transaction costs, while the periphery becomes increasingly diversified, notably in the South where traditional industrial activities are being replaced by service activities. These results suggest that the evolution pattern of employment growth in Luxembourg is very similar to that of some larger metropolitan centres, owing to its exceptional financial service activities.  相似文献

Abstract

Since the mid-nineteenth century, the Phunoy in Phongsaly province have been closely linked with the state in Laos through their role in defence, yet state intervention in their affairs has remained minimal. Villages have traditionally organised their own social and economic lives without interference at household or community levels. Since the first half of the twentieth?century, successive states in Laos have attempted to benefit from Phunoy villages, but they have had limited and transient success. For the last 15?years, however, the state has become a more significant reality for villagers, with a swath of policies implemented locally: resettlement, land reform, mandatory commercial plantations, a shifting cultivation ban, a hunting ban, etc. This synergistic cocktail has contributed to drastic and irreversible changes in village livelihoods and the landscape. Surprisingly, the Phunoy have not reacted publicly to this drastic revolution of their livelihood. I investigate whether their apparent lack of resistance is a counter-example to the more widely-debated concept of “Zomia”. I conclude that the Phunoy resist the state at the family level, and move away from their former homes, leaving behind a deserted landscape.

This paper presents new carbon, nitrogen and sulphur isotope data for European fallow deer (Dama dama dama) in Roman Britain and discusses results in light of evidence from classical texts, landscape archaeology, zooarchaeology and the limited available samples of metric data. The new isotope data presented here are from Fishbourne Roman Palace (Sussex), two sites on the Isle of Thanet (Kent) and a further two sites in London. In spite of small sample sizes the data make an important contribution to the very limited corpus of scientific research on the species and provide new resolution to the nature of fallow deer movement and management in Roman Britain.  相似文献
