Terrestrial laser scanning intensity data applied to damage detection for historical buildings

This paper presents a methodology to combine the technology of the terrestrial laser scanner with the techniques of digital image processing in order to study damages on stony materials that constitute historical buildings. This methodology has been tested using intensity data from three terrestrial laser scanners with different technical specifications. The unsupervised classification algorithms were used for the classification of 2D intensity images derived from the 3D information obtained from laser scanner equipment. The results obtained show the potential of the use of intensity data from terrestrial laser scanner for the recognition and characterization of certain pathologies in building materials that constitute historical buildings.     

Populism,Hegemony, and the Politics of Natural Resource Extraction in Evo Morales's Bolivia

Is populism necessary to the articulation of counter‐hegemonic projects, as Laclau has long argued? Or is it, as ?i?ek maintains, a dangerous strategy, which inevitably degenerates into ideological mystification and reactionary postures? In this paper, I address this question by exploring the politics of discourse in Evo Morales's Bolivia. While, in the years leading to the election of Morales, a populist ideological strategy was key to challenging neoliberal forces, once the hegemony of the new power bloc was stabilised, indigenous demands for emancipatory socio‐environmental change began to be perceived as a threat to resource‐based accumulation. In this context, the populist signifiers that originated in indigenous‐popular struggles were used by the Morales government to legitimise repression of the indigenous movement. I argue, therefore, that ideological degeneration signals a problem not with populism per se, but rather with the class projects and shifting correlations of forces that underpin it in changing conjunctures.     

DO FEDERAL DEFICITS MOTIVATE REGIONAL FISCAL (IM)BALANCES? EVIDENCE FOR THE SPANISH CASE

This paper studies the vertical and horizontal interactions between federal and regional governments in terms of public deficits. Recent studies commonly restraint budget slippages to the incentives created by the institutional arrangements within a country. Alternatively, we estimate here a fiscal reaction function for the Spanish regions over the period 1995–2010, paying special attention to the impact of the federal fiscal stance on regional fiscal imbalances. Our results indicate that higher public deficits for the central government encourage larger fiscal imbalances at the regional level. This vertical interaction is interpreted in the context of yardstick competition models. We also find a significant impact from fiscal decisions taken by governments at the same decision‐making tier in a specific region.     

Beyond the Anthropocene: Defining the Age of Destruction

The question of the Anthropocene has gained increased notoriety among archaeologists recently. Precisely because of that, it is in need of thorough critique. The aim of this article is not to rule out the concept of Anthropocene, but to point out some of its problems: the relationship of Anthropocenic discourses with the emergence of an all-embracing biopolitical science; the inadequacies of the term, which blames all humans equally for a specific effect of modernity and capitalism; its failure to accept a diversity of origins (but also the problem of accepting overly deep origins), and the shortcomings of adopting a geological framework for archaeology. I thus suggest that the discipline has to define its own eras – also for the contemporary period – and that the Age of Destruction could be an apt archaeological counterpart for the Anthropocene. One of the benefits of outlining an archaeological era is that it brings modernity and capitalism back to the fore, and with them issues of power and conflict that have been largely lost in recent post-anthropocentric debates.     

The Upper Paleolithic Rock Art of Iberia

Nearly 200 rock art sites of Upper Paleolithic age are currently known on the Iberian Peninsula, in both caves and the open air. Over half are still concentrated in Cantabrian Spain and they span the period between c. 30–11 kya, but–tracking the course of human demography in this geographically circumscribed region–many of the images were probably painted or engraved during the Solutrean and, especially, Magdalenian. Dramatic discoveries and dating projects have significantly expanded the Iberian rock art record both geographically and temporally in recent years, in close coincidence with the growth of contemporaneous archeological evidence: cave art loci in Aragón and Levante attributable to the Solutrean and Magdalenian, many cave art sites and a few open-air ones in Andalucía and Extremadura that are mostly Solutrean (in line with evidence of a major Last Glacial Maximum human refugium in southern Spain), the spectacular Côa Valley open-air complex in northern Portugal (together with a growing number of other such loci and one cave) that was probably created during the Gravettian-Magdalenian periods, and a modest, but important increase in proven cave and open-air sites in the high, north-central interior of Spain that are probably Solutrean and/or Magdalenian. Despite regional variations in decorated surfaces, themes, techniques and styles, there are broad (and sometimes very specific) pan-Iberian similarities (as well as ones with the Upper Paleolithic art of southern France) that are indicative of widespread human contacts and shared systems of symbols and beliefs during the late Last Glacial. As this Ice Age world and the forms of social relationships and ideologies that helped human groups survive in it came to an end, so too did the decoration of caves, rockshelters and outcrops, although in some regions other styles of rock art would return under very different conditions of human existence.     

Una relectura de la cronología de los incas de la Miscelánea antártica de Miguel Cabello Valboa (1586)

El presente artículo propone una lectura de la cronología de los incas presente en la Miscelánea antártica (1586) de Miguel Cabello Valboa a la luz de nueva evidencia histórica y textual. La crónica de Cabello ofrece años concretos asociados a la duración y expansión del Tawantinsuyu, razón por la cual fue utilizada por John Rowe (1945) para construir una cronología absoluta para el incario. No obstante el trabajo de Rowe ha sido cuestionado en las últimas décadas por la arqueología, la cronología de Cabello nunca ha sido abandonada del todo. El presente artículo postula que la comparación de fechas entre el registro arqueológico y etnohistórico no es correcta, puesto que parten de premisas distintas. Proponemos que los cálculos de Cabello se basaron en supuestos no empíricos los cuales, más que retratar el pasado verdadero de los incas, buscaban posicionar su historia dentro del providencial esquema que Dios había trazado para la Monarquía hispánica.     

Sustainability of the tourist supply chain and governance in an insular biosphere reserve destination: the perspective of tourist accommodation

ABSTRACT

Small islands in peripheral regions are currently perceived as attractive tourist destinations. Governance plays an important role as a strategy for the revival of such destinations to achieve a more productive, environmental, social and sustainable management structure. ‘Good’ governance of a destination depends on all the actors involved in the tourism network. Such governance requires a redefinition of relations between government and society and minimal boundaries between public and private sectors. This paper has analysed the level of implementation of corporate social responsibility (CSR) in a tourist destination that is a biosphere reserve (BR), the island of Fuerteventura (Canary Islands, Spain), from a comprehensive approach involving a tourism supply chain (TSC) with private and public agents. The focal firms analysed within the TSC have been tourist accommodation establishments in Fuerteventura. The paper shows that the level of involvement of tourist accommodation in CSR is positive. However, this involvement is not sufficiently high to meet the requirements of a destination designated as a BR. Therefore, coordination policies should be developed that promote governance systems and further enhance sustainability in the destination.
