This study is focused on the El Milagro mine (Asturias, Spain) and is part of a large‐scale effort on the measurement of the lead isotopic composition of Spanish copper ores from prehistoric mines in the provinces of Asturias and León, from which no data were available until recently. Lead isotopic values are compared to the published lead data from the El Aramo mine in the same region. The results show that both mines have a very similar lead isotopic composition, apart from some highly radiogenic samples in the El Milagro mine, which are clearly different from those previously reported for the Iberian Peninsula. 相似文献

Handaxes, simple flakes and retouched flakes are three types of stone tools whose adaptive advantages are highly debated. Interpretations of these technologically different tools suggest that their adequacy for butchery is uneven. Although some experimentation has been made in this regard, further research is needed to understand which of these tool types are more efficient for butchery, thus granting adaptive advantages to the hominins who used them. The present experimental work shows that small handaxes provide higher return rates in butchery activities than simple and retouched flakes. Efficiency (measured in time) is significantly positive in handaxes compared to the other tools when defleshing. In contrast, when comparing the three stone tool sets (simple flakes, retouched flakes and handaxes), the return values obtained for disarticulation are very similar. This study also shows that cut marks do not occur randomly and are less stochastic than previously assumed. Defleshing leaves a preferential cluster of cut marks on mid‐shafts from long bones and even on these sections, depending on element type, patterns are statistically demonstrable. 相似文献

Why did Turkey and Iran fail to become close partners in the 1970s even though they had compelling reasons to do so? This article argues that mutual distrust between Turkish and Iranian leaders, domestic turmoil in the two countries, and diverging geostrategic priorities undermined Ankara and Tehran's efforts to deepen their relations. While the shah of Iran saw his country as the policeman of the Persian Gulf and the Middle East, successive governments in Turkey continued to look west for their security. As economic and political turmoil engulfed the two countries, leading to a revolution in Iran in 1979 and a coup in Turkey in 1980, Iranian and Turkish leaders could not forge a lasting partnership. 相似文献

Carbon sequestration in community forests presents a major challenge for the Reducing Emissions from Deforestation and Forest Degradation (REDD+) programme. This article uses a comparative analysis of the agricultural and forestry practices of indigenous peoples and settlers in the Bolivian Amazon to show how community‐level institutions regulate the trade‐offs between community livelihoods, forest species diversity, and carbon sequestration. The authors argue that REDD+ implementation in such areas runs the risk of: 1) reinforcing economic inequalities based on previous and potential land use impacts on ecosystems (baseline), depending on the socio‐cultural groups targeted; 2) increasing pressure on land used for food production, possibly reducing food security and redirecting labour towards scarce off‐farm income opportunities; 3) increasing dependence on external funding and carbon market fluctuations instead of local production strategies; and 4) further incentivising the privatization and commodification of land to avoid transaction costs associated with collective property rights. The article also advises against taking a strictly economic, market‐based approach to carbon sequestration, arguing that such an approach could endanger fragile socio‐ecological systems. REDD+ schemes should directly support existing efforts towards forest sustainability rather than simply compensating local land users for avoiding deforestation and forest degradation. 相似文献

Outright victories against urban elitisation are rare in the current urban revolution. This article highlights how urban elitisation is confronted in Chacao, the most elite and urban part of Venezuela. Initially it reviews how this urban elitisation created the main economic, political and military strongholds of the opposition to the Bolivarian revolution. Then, in contesting it, the urban and Bolivarian revolutions feed each other through women's participation in invited and invented spaces of citizenship. From such spaces, Chacao women in their settler's movement organised struggles of insurgent citizenship to stop elitist urban renewal agendas and develop further forms of insurgent urbanism to conduct an urban renewal from below and establish a New Socialist Community for 600 families. They emerged as a revolutionary class to implement Bolivarian policies addressing the inefficiency and opportunism of the bureaucratic state and contesting urban elitisation with an anti‐capitalist and anti‐imperialist insurgent urbanism. 相似文献

The conceptualisation of intersectionality has been one of the most important contributions to feminism, as it allows for theorisation about multiple and intersecting oppressions. This contributes to a more complex and dynamic understanding of social relations and power structures, and it acknowledges the differences between categories, but it has no methodological direction. I try to take this debate a step forward, by developing what I have called Relief Maps: a new way of collecting, analysing and displaying intersectional data. I consider Relief Maps to be a sound tool for studying the Geographies of Intersectionality, as they show the relationship between three dimensions: power structures (the social), lived experience (the psychological) and places (the geographical). By showing some examples of them, I demonstrate how Relief Maps make empirical work on intersectionality possible and how they are able to take into account both privilege and oppression without using categories in a fixed and rigid way. Taking the spatial dimension as a central part of the analysis, they show how the relationship between power structures varies depending on places and also illustrate how subject formations are done and undone through everyday spaces. Relief Maps aim to take the potentialities of intersectionality and minimise its limitations: they intend to disrupt homogeneous categories while pointing towards the material consequences of oppression. Finally, Relief Maps also provide some insights on intersectionality itself, as they help to think about how power structures relate to each other and the role that experience and place play in these processes. 相似文献

This paper analyses the effects of R&D expenditure in the higher education sector on the scientific production across regions in Europe 15. Our research questions relate to the regional production of science and the role of academic R&D expenditures on regional scientific output. The results show that money affects the production of scientific results in regions. On average, we found different impacts and lags of R&D expenditure according to the level of regional development. Our findings also suggest that scientific specialization is a significant factor affecting scientific outputs, although its effects differ across disciplines and regions. 相似文献

This article deals with the ways in which different political conflicts surrounding the emergence, independence, and consolidation of Castile as a political agent are managed and solved in the Poema de Fernán González. It shows how internal conflicts within the Castilian community are settled by favoring an authoritarian vision of leadership, discouraging consensus and shared decision making. Regarding conflicts with other political domains, the poem legitimizes Castilian independence by means of a narrative that makes natural Castilian claims on Visigothic heritage, while at the same time presenting Castile as following legal procedures and as a victim of external aggression. 相似文献

This paper examines the evolution of regional innovation policy in Emilia-Romagna and Valencia, two regions with similar economic features that implemented close innovation policies in the 1970s and 1980s. We investigate whether their similarities have led to parallel targets, policy tools and governance developments. We show that innovation policy in both regions suffered from the effects of privatization, budget constraints and changes to manufacturing during the 1990s and we highlight the consequences. Although Emilia-Romagna experienced deeper changes to its innovation policy, privatizations and/or the replacement of public funds promoted commercial approaches and induced market failures in both regions. The worst effects of these policies were the implementation of less-risky innovation projects, the shift towards extra-regional projects and markets, and the favouring of large firms. 相似文献
