In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km. 相似文献

Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired Aguada Portezuelo decorated pottery. Surface paintings in black, white, red, brown, burgundy and ochre were analysed. Major, minor and trace elements were detected by PIXE, whereas XRD and SEM-EDS gave information on the main mineral phases and the characteristic morphology for each analysed pigment. The results obtained indicate that the main colour groups can be easily discriminated by PIXE, and they are characterized by only one pigment for each colour: hematite (red) and manganese mineral oxides (black), respectively, whereas white pigments are characterized by calcite, ghelenite and gypsum. 相似文献

This paper demonstrates the positive effect of immigrant entrepreneurs on manufacturing exports over and above that of diasporas. Using small-scale regional administrative data, our instrumental variable estimates of export gravity models imply that ceteris paribus, that is, holding constant the total number of immigrants, the expected protrade effect of a migrant becoming an entrepreneur amounts to an average increase of US$5,946 in the export flows toward her country of origin. Besides these dyadic effects, immigrant entrepreneurs unlike nonentrepreneurial immigrants raise a region's overall competitiveness and export flows toward other destinations as well. 相似文献

This article contributes to theorising the often unrecognised continuities between the illegalisation of migrant and refugee mobilities as an effect of lawmaking or other state practices of border policing and immigration law enforcement and the illegalisation of the rights, claims, and juridical status of minoritised citizens. Against a backdrop of resurgent right-wing nationalisms, we pursue this transversal analysis of state practices of illegalisation to draw attention not only to labour subordination and disposability but also the more fundamental relationship between law and terror. The making of such regimes of citizenship takes place in obvious ways at the ostensible outer edges of nation-state territories. They are also replicated in the various spatial arrangements that ensure racialised dispossession within global cities, cities that are better understood as reconfigurations of settler-colonial cities. We argue that the study of practices of illegalisation allows critical poverty scholarship to better discern how sociopolitical categories and classifications that are central to wider processes of marginalisation and domination may arise or be reinforced as effects of the state’s legal productions of illegality. 相似文献

Power to the people: when culture works as a social catalyst in urban regeneration processes (and when it does not) 总被引:1,自引:0,他引:1
This article focuses upon the relationship between culture, urban regeneration schemes, and their impact on socio-cognitive assets – namely, social and human capital. It examines three major urban regeneration projects in the districts of Saint Michel (Montreal, Canada), Auburn (Sydney, Australia) and Bicocca (Milan, Italy), where culture has been invoked as a main transformational driver at the economic and socio-environmental levels, but with different approaches and results. Through comparative analysis, we develop a more general reflection on the social impact of culture-led urban transformation processes, questioning the actual role of cultural initiatives – particularly those related to the creation of new cultural facilities and the programming of big cultural flagship events – and participation as a means to improve the local social milieu. We find that a key role for social efficacy is played by projects’ capacity to elicit the commitment of residents through inclusive cultural participation, as opposed to instrumental top-down initiatives mainly addressing city and neighbourhood branding and real estate marketing purposes. 相似文献

AbstractThis article reconstructs the dynamics of delegitimation of political opponents in the Italian Christian Democratic Party (DC), which had a relative majority and almost uninterruptedly led Italy’s governments from 1945 to 1992. The DC built its strategy of delegitimation on two levels, an ideological-religious one and a systemic one, which were only partly interdependent and overlapping. In almost half a century, the DC aimed its rhetoric and politics of delegitimation mainly at those opposition parties it considered as anti-establishment, that is, the Italian Communist Party (PCI) and the neofascist Italian Social Movement (MSI), and the form of delegitimation changed a great deal over this period. However, it is possible to grasp a specific dynamic: from a rigid form of delegitimation, from time to time it became possible to legitimate (at least in part) the opposition parties at different times and in different ways, depending on the changes in the political sphere and in society. It was a process full of contradictions and ambiguities within which the political enemy gradually gave way to becoming a political opponent. 相似文献

HISTORICAL LEGACY AND POLICY EFFECTIVENESS: THE LONG‐TERM INFLUENCE OF PREUNIFICATION BORDERS IN ITALY

This paper investigates the interplay between cultural traditions and policy effectiveness. It explores the differential impact of a large development program (Cassa per il Mezzogiorno), implemented for four decades, starting in the 1950s, to stimulate convergence between Italy's south and the more developed north, on municipalities with different histories. Namely, we consider a sample of municipalities located on either side of the historical border of the Kingdom of the Two Sicilies, whose legacy is considered, from Putnam onwards, to be a prime‐facie cause of Southern Italy's underdevelopment. Having been part of the Kingdom of the Two Sicilies is associated with a negative impact of development policies, but only when the allocation of development funds through the Cassa per il Mezzogiorno suffered from low quality of governance and was driven by political considerations rather than by efficiency ones. 相似文献

THE IMPACT OF LOCAL WAGE REGULATION ON EMPLOYMENT: A BORDER ANALYSIS FROM ITALY IN THE 1950s*

This paper measures the impact of wage zones—compulsory wage differentials at the province level—on Italy's local labor markets during the 1950s. Using spatial regression techniques, it finds that for the industrial sectors covered under wage zones there was an increase in employment when one crossed the border from a high‐wage province into a low‐wage one; the effect diminished, however, as the distance from the boundary increased. The paper also illustrates that the impact on the overall (nonfarm) private sector, which includes both covered and uncovered sectors, was negligible. 相似文献

Grasslands pose a particular problem for archaeological survey involving artifact assessment, as no material is plowed up to the surface. Although finds in molehills are often the only source of information available on sites with such low visibility, an archaeology of molehills has thus far been largely disregarded. Yet, by applying a low-cost and time-efficient methodology, both the potential and the pitfalls of molehill archaeology come to the forefront. At the medieval harbor site of Monnikerede, it was possible to assess material culture and to locate certain structural elements. However, when artifact densities were compared with the underlying geophysical anomalies, a more complex relationship appeared at the level of individual features. 相似文献
