The shift from the linear to the innovation system-based approach has resulted in the emergence of differentiated regional innovation policy. However, certain common presumptions bind these location-specific policies together. The set of information that is used to design these policies and the set of information excluded are fairly similar. The theoretical sections of this paper provide a critical review on the informational basis of regional innovation policy by contrasting the interpretations of the welfare effects of technological change in the utilitarian tradition and in Sen's capability approach. The empirical sections analyse the correspondence of the innovation capacity and welfare (well-being) situation in a Hungarian micro-regional data set. We conclude that the conventional informational basis of innovation policy is too narrow from a welfare perspective. Not only should the differences in the innovation systems, but also the peculiarities of the region's welfare situation be considered during the design of innovation policy.  相似文献

Fragments of charcoal are present in floodplain alluvium of the San and Strwi?? rivers in the Polish part of the Bieszczady Mountains, Polish East Carpathians. They occur as single clasts or in lenses in the basal part of fine-grained alluvium, together with unburnt wood debris, or in the middle part of the vertical sequence of the floodplain alluvium. 14 samples of charcoal from the upper courses of the San (ca. 50 km) and the Strwi?? (ca. 10 km) were dated with radiocarbon. The obtained dates fall mainly in the 15th through 19th century interval; only one sample is markedly older (9th–10th century). Taxonomic composition of the charcoal source wood was also studied and compared with that of coeval forests. Correlation of the charcoal age with the history of economic development of the studied region indicates that charcoal is of anthropogenic origin: older charcoal from intense slash-and-burn deforestation, while younger charcoal was produced by local industries.  相似文献

The purpose of this article is to explain and discuss the essential operational characteristics of the technology of power (sensu Foucault) perpetrated on the internal frontiers with the Indians in nineteenth-century Argentina. The conquest and colonization of the Pampas took shape in the establishment of military camp structures placed to create a defensive cordon, known as “the Indian frontier line.” These constructions were fortlets defended by gaucho cavalry squadrons (know as Blandengues during the Spanish period, and then Guardias Nacionales after Argentinean Independence). This process is known in Argentinean historiography as “the conquest of the desert.” This particular technology of power existed in this historical context and operated at every social level, impacting strongly on the lower classes that inhabited the incorrectly named “desert.” Its implementation in the military field enabled the existence of an array of micro-powers that surrounded the gaucho, called vago y malentretenido—“a vagrant and lingerer”—and their women's lives. The army as institution was the locus of various forms of coercion and old forms of punishment (such as the stakes, whipping, and public executions) most of which affected peasants, nonresidents, itinerant workers, and the rural youth. This schema was adopted in different areas: in the enrolment and discipline of the gaucho soldiers, in life in the fortlet-prisons, and in the ritualism of power. The alternative chosen by soldiers to evade this technology of power and the fortlet-panopticons was escape through desertion. The utility of those observations is demonstrated, because an important part of the area of research of historical archaeology that has developed with the greatest impetus in Argentina has taken fortlets as its subject of study.  相似文献

Archaeological research in central‐northern Patagonia (Atlantic coast and lower the valley of Chubut river) showed that this area was used since at least the Middle Holocene. Stable isotope analyses (13C and 15N) of human bone samples indicate that hunter‐gatherers living in that area had a terrestrial‐marine diet including guanaco meat, land plants, mollusks and pinnipeds. Despite this general trend, intersite variability and changes through time were noted, especially after the late Holocene. These results have been reinforced by archaeofaunal, technological and bioarchaeological records. In this paper, three hypotheses are examined: (a) the diet of these populations was complete and rich enough to ensure good health status and avoid nutritional deficiencies; (b) carbohydrate consumption increased progressively after 1000 BP, when pottery technology was adopted and (c) this kind of mixed diet would have been qualitatively more nutritious than that of other populations of the region, which would have resulted in better nutritional and healthy conditions. These three hypotheses are compared with dental results obtained from 563 permanent teeth from 45 individuals (34 adults and 11 juveniles from both sexes), rescued from burial sites. Indicators of oral health were assessed through the observation of caries, abscesses, wear, pulpar cavity exposure and ante mortem loss. Features of nutritional status such as enamel hypoplasia, porotic hyperostosis and cribra orbitalia were also examined. Given the availability of direct radiocarbon dating for most of the sample, three temporal series were determined: ‘Before 1000 BP’, ‘1000–5000 BP’ and ‘Post‐contact’. No evidence of alimentary stress or iron deficiency was found in individuals from the three series, which accounts for healthy and good nutritional life conditions. After 1000 BP, the results show a progressive increase in the caries percentage and a decrease in abscesses, dental wear and ante mortem losses frequency. This is possibly related to more consumption of processed foods in the last 1000 years. These results were compared with similar studies based on samples from different environments and latitudes of Patagonia. Evidence suggests that mixed diets (marine‐terrestrial) would have been more appropriate and nutritionally complete than exclusively marine or terrestrial diets.

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献

This paper examines the spatial distribution of the Internet in the European regions. To achieve this aim, our analysis combines a set of non-parametric techniques proposed in the context of the economic growth literature, with various spatial econometric instruments. The results reveal that regional disparities in Internet adoption are greater than territorial inequalities in gross domestic product (GDP) per capita. In addition, our findings show that the distribution under consideration is characterized by the presence of positive spatial dependence, which implies that physically adjacent regions register a similar degree of Internet adoption. Finally, the analysis carried out allows us to assess the role played by variables such as GDP per capita, unemployment rate, stock of human capital and population density, in explaining the spatial distribution of the Internet in the European Union.  相似文献

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.  相似文献

Archaeological evidence shows that populations used to transverse the Sahara Desert throughout the Holocene despite the extreme temperatures and the rough physical terrain. The current paper examines whether the desert inhibited extended gene flow among populations by means of cranial morphology as captured by geometric morphometrics. The examined populations include the Garamantes, a group centered in Southwest Libya and largely controlling trans-Saharan trade, and various Egyptian, Tunisian and Sudanese groups dating to the Middle and Late Holocene. The results showed that most inter-population comparisons were statistically significant and therefore all populations appear more or less distant to each other. The Mahalanobis biodistance measure identified four clusters. The first consists of the Garamantes alone, the second includes the populations from Kerma and Gizeh, the third includes the Badari and Naqada, while the fourth consists of the samples from Algeria, Carthago, Soleb and Alexandria. Moreover, the distance of the Garamantes to their neighbors was significantly high and the population appeared to be an outlier. This is attributed to the location of the Garamantes at the core of the desert, indicating that, despite the archaeological evidence, the Sahara Desert posed important limitations to gene flow between the Garamantes and other North African populations.  相似文献

The problems of interpretation of many overlapping species lists of fossil assemblages are discussed using the example of insect faunas from a late medieval farm site in southern Iceland. Numerical techniques were employed, principally those available within the CLUSTAN package, and it was concluded that a considerable refinement in interpretation was achieved. Such quantitative procedures are suitable for groups other than fossil insects but their employment cannot be regarded as a substitute for, rather than an adjunct to, a sound ecological approach.  相似文献
