Examination of stone artefacts from Maiden Castle, Dorset, led to the identification of a Neolithic saddle-quern which originated in central Normandy. While stone axes from Brittany and jadeitite axes from the Alps have long been known from central southern England, the quern is the largest and heaviest Neolithic import yet identified. It has a bearing on the debate about indigenous or immigrant origins for the Neolithic, but also re-opens the question of the type of boat that plied the Channel at this early period. It is argued that logboats, for which there is evidence, should not be overlooked in favour of skin-boats for which there is none.

The Portuguese revolution of October 1910 instituted a civilian revolutionary and ‘progressive’ Republic within the background of a conservative and monarchist Europe, whose core was located in the countries of the Triple Alliance. Since its very beginning, the regime fell short of any foundational consensus and was caught by a wave of conspiracies, upheavals, social protests and civil war menaces. This article sheds light on the shortcuts adopted to overcome the political instability examining political procedures like legislative coups, wishful thinking and ad hoc planning. The final part broadens the debate through the assessment of the time frames and the types of effects that policy failure is able to bring about.  相似文献

We see what we are prepared to see. Scientific research aims at breaking down this situation, analysing its subjects/objects of study from different points of view. Although multiple meanings can be derived from every question and a myriad of positions can be adopted, some are bound to be silenced by traditional criteria of authenticity. Archaeology is not an exception to this: the prevailing agenda severely impacts on our perception of what archaeological practice consists. In turn, its ethos is recreated as part of our own identity processes through our productions, whether by passively accepting monolithic standards or by dynamically proposing alternative positions in response. The study of the prehistoric and colonial periods in America can be a good test bed for surveying the influence of academic background upon the analysis of human history. Here we review two Spanish journals of American studies to discuss the different orientations of the authors according to their provenance. Plotted against the country represented by the authors, we consider his/her research as regards the object of study (ie. artefacts/written sources), its origin, chronology and, finally, the aim of the paper. We found interesting orientations in relation to focus on particular subjects, most probably conditioned by the ontology of the researchers. Although the selection is quite taxative, it may usefully complement studies carried out in the Americas.  相似文献

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.  相似文献

The lithic assemblage from the Middle Palaeolithic site of Payre (Rhone Valley, France) contains a large number of convergent tools and pointed tools of various shapes, sizes and retouch types. These were excavated from several archaeological units, dating from marine isotopic stages 8–5, which also yielded human skeletal remains. Consideration of this large tool kit has led to an improved analysis of Middle Palaeolithic tools with two retouched convergent edges. The 350 tools were not described within the classical typological framework, but, rather, from a lithic technological perspective in relation to a discoid debitage. In addition, an initial macroscopic use-wear analysis aided in establishing whether they were used according to their technical and/or morphological features. The Middle Palaeolithic convergent tools from Payre are shown to be quite diversified, and the question of the significance of the retouch and the definition of the various types is addressed. Initial functional results indicate that a clear relationship between shape and function cannot be easily established, and that these tools were used as hand tools. This study contributes to the debate on the use of stone tip spears in the Early European Middle Palaeolithic.  相似文献

The aim of this paper is to analyse some relevant aspects on productivity distribution in the European Union at regional level. Firstly, the paper examines its external shape and intra-distribution dynamics. Subsequently, an analysis of the factors that might be behind the productivity distribution and its dynamics is carried out. The results, represented by means of a relatively new visualization tool, highlight the role played by factors such as geographical location, compensation per employee and investment per employee in explaining this issue.  相似文献

Recent research has stressed the need to evaluate the economic implications of urban planning policy. In this article, we present empirical evidence on the impact of this policy on the population growth of towns and cities. A simple theoretical model serves to highlight the mechanisms whereby this policy may affect urban growth. The model yields a reduced-form equation which we estimate for the towns and cities of Andalusia (Spain). The empirical model strongly supports the claim that urban planning policy considerably affects urban growth and thus, the distribution of population across space. Our results suggest that urban planning policy is contributing to the reduction of diseconomies of agglomeration in larger cities. On the negative side, we find that urban plans are subject to obsolescence, which slows down growth.  相似文献

Recent research in Paleolithic archeology has stressed the importance of temporal issues in assemblage interpretation. Archeological assemblages are temporal constructs, formed by the addition of an unknown number of depositional events. This temporal dimension is also evident at the artifactual level, since single artifacts may undergo different events of modification and/or uses over time. The recycling of previously discarded blanks for tool production is one of the best examples of the temporal nature of artifacts. The aim of this paper is to evaluate the importance of recycling in a Late Upper Paleolithic site, examining a type of artifact – burned tools – that has up to now been little used to approach this issue. Our results suggest that recycling was probably a significant component of Upper Paleolithic provisioning behavior, with important implications in site formation processes and the typological variability of assemblages. The expedient or curated character of recycling is also discussed.  相似文献

This article comments upon the situation of sprawl in Spain and Madrid, especially residential sprawl. It does not appear to be a serious problem due to its low starting point, but artificial surface and residential sprawl is growing rapidly. For that reason, it may be an issue in the future. Between 2000 and 2006, urban residential land use grew 0.4% in Spain and 0.2% in Europe per year, land use of industrial and commercial areas grew 2.3% in Spain and 0.4% in Europe and total artificial surface grew 2.7% in Spain and 0.6% in Europe (EEA, 2010). Further, we will study the legislation on maximum and minimum urban density in Spain. The highest maximum urban density is established by the Basque Country, with 230 dwellings per hectare, and the highest minimum urban density is established by Catalonia, with 50 dwellings per hectare. In both cases, it is applied to only certain types of territories. Finally, we will analyse what happens in the Region of Madrid in relation to sprawl. It has very similar patterns compared with the rest of Spain, although more pronounced.  相似文献
