Reccopolis was a new urban foundation of the late sixth century AD, built by King Liuvigild during the period of the Visigothic state formation. The city was equipped, alongside other facilities, with an aqueduct built ex novo in the Roman technique. This has only recently been studied. The construction of a new city and a new aqueduct indicates a great economic effort by the Visigothic ruler: the event was in itself also a grand act of propaganda in addition to its obvious functional purpose. The aqueduct is itself unmatched in public constructions of this period.  相似文献

ABSTRACT

This paper analyses the ambiguities of post-Apartheid public cultural policies in South Africa by focusing on the case of the Red Location Museum and Cultural precinct (RLMCP), a multisectoral project for socio-economic development, based on tourism, art, culture, heritagisation and urban regeneration, implemented in Red Location, one of the oldest townships of Port Elizabeth. In the post-Apartheid period, cultural policies have been employed as catch-all policies that could lead to urban renewal, desegregation and development. The case of the RLMCP drives home how efforts to use art and culture as leverages to transform townships into the core of the creative city and into the prototype of a new form of neighbourhood led to exclusionary representations and patterns; moreover, it is an example of how cultural policies enforce gentrification dynamics at the local level, in the name of restructuring urban governance and rescaling the city to the global dimension.  相似文献

Hydrodynamic sorting is a taphonomic process able to transport and scatter bones deposited in archaeological and paleontological sites. This study presents the results of experimentation performed in an artificial flume with guanaco (Lama guanicoe) bones of different ontogenetic development, dry and saturated in water, in hydric flows velocities of 15 and 30 cm/s. The obtained results show that bone global density, the age of the individual, the dry or wet bone state, and the hydric flow velocity influence significantly bone dispersion. In this way, bones from immature individuals with unfused secondary growth centers and relatively low bulk density have better possibility of being transported than fused bones from adult individuals. Taking into account the results obtained in this experimentation and the feasibility of discriminating age categories in fossil assemblages, two bone groups with differential potential transport are presented in this paper. These transport groups constitute a methodological tool to evaluate the role hydric current may had played in the formation of a fossil assemblage.  相似文献

The article reports on the street protests that took over Spanish cities earlier in May and June. The protests have been explained as a response on the part of new media democratic networks to the governance of the economic crises by corrupt political and financial classes. We offer here a tentative chronology of the events, and essay instead an argument about a revitalised municipalist tradition, that sees in the plaza the centrepiece of new forms of do‐it‐yourself political action.  相似文献

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800–3000 cal BC), Chalcolithic (ca. 3000–2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500–2200 cal BC) and the Bronze Age (ca. 2200–1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by evidence of trauma and disease found on numerous skulls in the collection. Since no clear associations of specific grave goods with certain individuals based on sex or age could be determined, the only suggestion of social inequality lies in the burial practice itself, where certain individuals were interred in caves while others were not.  相似文献

Sub-national economic policies increasingly use labor market areas (LMAs) rather than administrative areas for analysis and implementation. How a set of LMAs was defined influences the results of such analyses, and so accurate policy delivery needs appropriately defined LMAs. Multinational bodies need comparable LMA definitions in many countries, calling for a definition method that is transferable across national boundaries. This article applies quantitative metrics to evaluate LMAs defined in three contrasting countries by three methods that represent the main methodological approaches. The deductive approach—based on a center and hinterland—is too inflexible to deal with differing geographical circumstances and cannot cope with statistical zones that are very small, or do not respect settlement structure. The alternative inductive methods tested define appropriate LMAs in each country, with the newer method performing slightly better in statistical terms. The article also exemplifies the usefulness of the metrics for comparisons of alternative regionalizations.  相似文献

ABSTRACT

For many European rural areas, the rural development programmes based on the LEADER approach constitute the main policy for promoting tourism. Going a step further than a rural development programme, LEADER represents an ideal method for overcoming some of the challenges involved in rural tourism development, such as the integration of tourism supply through public-private organizations or the coordination of multi-level policies. Despite its potential, there are difficulties involved in putting this approach into practice. This article aims to provide in-depth understanding of the challenges faced by some managers responsible for developing tourism strategies through the LEADER approach. To do this, semi-structured in-depth interviews have been held with Local Action Groups managers from Castilla-La Mancha (Spain). The main findings reveal that the actions of regional governments lead to the limitation and strangulation of the principle of subsidiarity according with the LAG manager? opinion.  相似文献
