Prehistoric pottery decorated with incisions or impressions filled with white and seldom coloured inlays is well documented in the archaeological literature, but the related in-depth archaeometric studies are sporadic. 43 decorated ceramic shards, dating from the Neolithic to the Bronze Age, and an Iron Age fibula from the archaeological site of Castello di Annone (Piedmont, North-Western Italy) were analysed with FTIR, Raman and XRPD for characterization of the ornamental pigments forming these inlays. Few white components were used as fillers, namely talc and bone ash (hydroxyapatite – Bone White), often as a mixture and seldom accompanied by other pigments (i.e. kaolinite and presumably secondary calcite). Comparison with freshly-heated biogenic hydroxyapatite proved that ancient Bone White pigment was calcined at about 900 °C. Such a process was kept separate from pottery firing as these white mixtures show absence of talc degradation by-products and sporadic presence of kaolinite, implying these ceramics were decorated only after firing in furnace. Actual presence of fluorapatite in bone ash could allow dating with the Fluorine Method, but lack of fluorine detection with SEM-EDS causes such an attempt to be impracticable so far. A pilot comparative study with a restricted but representative group (11) of coeval finds from other sites of Piedmont suggests that while recurrence of talc prevails in Castello di Annone from the Neolithic throughout the Bronze age, massive use of bone ash (Bone White) becomes widespread in the close Iron Age settlements, possibly consequent to a more efficient handling of its production technology. 相似文献

We present a preview of our work for a critical anthology of medieval and pre-medieval fantastic folklore narratives about animals in the human body. These are generally referred to among English-speaking scholars as ‘bosom serpent’ legends. In particular, we provide here two of the most ancient texts from the section of the anthology on medieval Scandinavia. We also offer two little-known narratives, a medieval Latin saint’s life and one from the Byzantine Greek world. 相似文献

SummaryThis article deals with laissez faire arguments as distinguishable in Europe between the final decades of the nineteenth century and 1914. The focus is on Herbert Spencer and the British ‘Individualists’, the Italian Vilfredo Pareto, and the Frenchman Paul Leroy-Beaulieu. Analysis concentrates on the relationship between laissez faire formulations and democracy, the latter amounting to the impact of the extension of the franchise on representative government. All the mentioned authors blamed the mechanisms of democratic government for the contemporary growth in state functions. While Spencer focused on the threat of a new class legislation after the demise of aristocratic power, Pareto and Leroy-Beaulieu viewed the pressure of lobbies and parties as the chief cause of the extension of state interventions. This article also aims to detect similarities and differences with more recent formulations. It is argued that Friedrich Hayek's achievement was to reconcile, against earlier perspectives, laissez faire with democracy. The reconciliation rested on a conceptualisation of democracy as a valuable method or procedure, onto which no values should be grafted. 相似文献

This is the first publication reporting systematic analytical research conducted on archaeological metals from Cuba. The main focus of the study consists of beads and small metal objects excavated at the cemetery of El Chorro de Maíta, which comprises some of the richest funerary deposits so far recovered on the island. Some comparative samples from the nearby site of Alcalá were also investigated, with an emphasis made on the manufacture, composition and origins of the different alloys. The resulting picture is that members of the social elite of the indigenous Taíno peoples were buried with beads made of placer gold exploited locally, gold–copper–silver pendants brought from continental South America and, above all, brass lacetags from European clothing that were perceived as sacred metals. The archaeometallurgical approach offers fresh insight into the relationships between Europeans and Taínos, and the impact of colonization on the indigenous customs, values and social structures. 相似文献

The Impact of a Customs Union with the European Union on Internal Migration in Turkey 总被引:1,自引:0,他引:1

Abstract The impact of the recent Customs Union (CU) agreement between Turkey and the European Union on internal migration is studied using an intra‐industry trade Computable General Equilibrium (CGE) model with intersectoral capital mobility under two alternative specifications for the labor market: the traditional Harris‐Todaro approach and the existence of a “wage curve” in the urban sector. Under both specifications, the numerical results show that the CU is welfare enhancing and causes a reduction of the urban‐rural wage gap as suggested by theoretical studies. At the same time, it leads to rural‐to‐urban migration and raises the capital rent, results that are counter intuitive with respect to the dual economy literature. Furthermore, the rise in formal labor demand and the migration response to the CU have not resulted in an increase in urban unemployment (i.e. the “Todaro paradox”), but rather to a fall in the unemployment pool. The study also shows that the Bhagwati‐Srinivasan proposal of maximizing welfare by uniformly subsidizing the entire labor market is impracticable, especially if the high wage union sector can negotiate employment conditions. 相似文献

SummaryThe idea of interdisciplinarity can be articulated in different ways. The aim of the article is to criticise the view that interdisciplinarity is to be treated as a quality of the historian's approach to his subject-matter, and to argue for a constructivist interpretation of that notion. A constructivist account of interdisciplinarity relies on the thesis that the latter is one of the manifold ways in which it is possible to give sense to the historical records of which the historian wants to gain knowledge. In the paper it is maintained that the function of the notion of interdisciplinarity is to account for the clash of languages that can be found when disciplines converge. This new paradigm is highlighted by taking into consideration the history of American pragmatism. 相似文献

This paper examines the level and evolution of polarization in regional per capita income in the European Union between 1977 and 1999. In this analysis, non-parametric estimation techniques are combined with the calculation of various polarization measures. The results obtained suggest a decrease in regional polarization in the European context during the period analysed, as a consequence of various factors, at times working in opposite directions. The findings also reveal the existence of discrepancies between the evolution of polarization and regional inequality. Finally, the analysis carried out highlights the importance of the role played by the national component and the spatial dimension in the formation of homogeneous groups of regions linked by similar development levels in the distribution under study. 相似文献
