EMERGENCE OF LEAPFROGGING FROM RESIDENTIAL CHOICE WITH ENDOGENOUS GREEN SPACE: ANALYTICAL RESULTS

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.     

Intra-site Spatial Analysis in Ethnoarchaeology

ABSTRACT

The interpretative power of quantitative intra-site spatial analysis has long been recognised by archaeologists. On the contrary, very few ethnoarchaeological works have engaged with the statistical analysis of intra-site pattern of artefacts and ecofacts. Nonetheless, ethnoarchaeology is uniquely placed to guide and assist in the identification of sound techniques and in the development of the methodology of analysis. The possibility to directly connect the distribution of the proxies under study with the activity that generated such distribution, provide the means of fine-tuning the tools we use for identifying these patterns in the archaeological record. As a consequence, archaeological methodology and interpretation both benefit from the application of improved methodologies. In this paper we review some of the most common techniques used to analyse activity areas and we provide examples of the application of such techniques to ethnoarchaeological contexts. The aim is to assess how archaeology can benefit from the intra-site spatial analysis of ethnoarchaeological contexts.     

The Maritime Cultural Landscape of Northern Patagonia

This article is a contribution to the study of the indigenous navigation and its boats in the region of northern Patagonia. This article also aims to contribute to the understanding of indigenous navigation practices and technologies and their origins from prehistoric times to the mid-twentieth century. It presents and discusses the concept of Westerdahl’s Maritime Cultural Landscape in relation to other landscape concepts. This model is applied to northern Patagonia in order to discuss if it is possible to speak of a true maritime culture in the region. For this purpose, archaeological, historical and ethnographic data are presented in an integrative and innovative methodology for the discipline. Finally, the Maritime Cultural Landscape model will allow the integration of aquatic and terrestrial landscapes as routes traveled by native inhabitants of northern Patagonia and southern Chile, and propose an important and diversified maritime, river and lake tradition.     

Cultural rights and their contribution to sustainable development: implications for cultural policy

Abstract

This article aims to analyse the meaning and implications of cultural rights for cultural policies concerned with sustainable development. Although references to both cultural rights and sustainable development have become widespread within cultural policy documents in recent decades, the actual conceptual and operational implications often remain vague, as an ambitious discourse that may conceal a poverty of resources and capacities. As a result, the ideal horizon suggested by cultural rights and sustainable development may not always be achieved in practice, nor are the mechanisms to achieve it always well known. In this respect, the article aims to dissect the actual requirements posed by cultural rights and sustainable development, including their different notions and areas of synergy and intersections, in order to shed light on relevant cultural policy approaches. To this end, a range of examples taken from a variety of contexts will also be examined as areas of expressed needs or areas of possible solutions.     

A Late Neolithic Case of Pott's Disease from Hungary

The aim of this study was to present classic bone lesions caused by tuberculosis, as seen in a Late Neolithic–Early Copper Age osteoarchaeological sample deriving from the site of Alsónyék‐Bátaszék (the western part of Hungary from the 5th millennium bc ). In one particular case of an adult male skeleton, vertebral bodies' destruction, collapse, ankylosis and marked angulation in the lower thoracic and the upper lumbal region of the vertebral column were observed. The collapse resulted in a severe gibbus formation. The paleopathological analysis was carried out using morphological observation supported by radiological analyses. The results from this study increase our knowledge of the early occurrence of skeletal tuberculosis in past populations. Copyright © 2012 John Wiley & Sons, Ltd.     

Reduction Factors for Seismic Design Spectra for Structures with Viscous Energy Dampers

A simple mathematical expression is proposed to estimate spectra reduction damping factors for seismic design of systems with viscous dampers. The expression is obtained from the ratios between ordinates of uniform hazard spectra associated with two different return intervals (50 and 125 years), corresponding to sites with different types of soil within the Valley of Mexico. The expression proposed depends on the dominant period of the soil, and on both the vibration period and damping ratio of the structural system. Values of the damping factors proposed here are comparable to those recommended by different authors and seismic design building codes.     

Polyphasic hydrothermal and meteoric fluid regimes during the growth of a segmented fault involving crystalline and carbonate rocks (Barcelona Plain,NE Spain)

A polyphasic tectonic‐fluid system of a fault that involves crystalline and carbonate rocks (Hospital fault, Barcelona Plain) has been inferred from regional to thin section scale observations combined with geochemical analyses. Cathodoluminescence, microprobe analyses and stable isotopy in fracture‐related cements record the circulation of successive alternations of hydrothermal and low‐temperature meteoric fluids linked with three main regional tectonic events. The first event corresponds to the Mesozoic extension, which had two rifting stages, and it is characterized by the independent tectonic activity of two fault segments, namely southern and northern Hospital fault segments. During the Late Permian‐Middle Jurassic rifting, these segments controlled the thickness and distribution of the Triassic sediments. Also, dolomitization was produced in an early stage by Triassic seawater at shallow conditions. During increasing burial, formation of fractures and their dolomite‐related cements took place. Fault activity during the Middle Jurassic–Late Cretaceous rifting was localized in the southern segment, and it was characterized by hydrothermal brines, with temperatures over 180°C, which ascended through this fault segment precipitating quartz, chlorite, and calcite. The second event corresponds to the Paleogene compression (Chattian), which produced exhumation, folding and erosion, favouring the percolation of low‐temperature meteoric fluids which produced the calcitization of the dolostones and of the dolomite cements. The third event is linked with the Neogene extension, where three stages have been identified. During the syn‐rift stage, the southern segment of the Hospital fault grew by tip propagation. In the relay zone, hydrothermal brines with temperature around 140°C upflowed. During the late postrift, the Hospital fault acted as a unique segment and deformation occurred at shallow conditions and under a low‐temperature meteoric regime. Finally, and possibly during the Messinian compression, NW‐SE strike‐slip faults offset the Hospital fault to its current configuration.     

Degradation Discourse and Green Governmentality in the Xilinguole Grasslands of Inner Mongolia

This article examines discourses about grassland degradation in China as expressed by herders, government officials and researchers, presenting findings from fieldwork in Xilinguole League, Inner Mongolia. Recognizing degradation discourse and grassland restoration policies as key sites of political contestation, this study does not try to arrive at the scientific facts about degradation, but rather seeks to illuminate the mechanisms by which grasslands are identified as degraded, and the implementation of policies to restore and protect the grasslands. A key finding is that policy outcomes are widely divergent and difficult to predict. This is not merely due to differences among actors in terms of their interests, access to resources, power, values or knowledge, but as much a result of contradictions and tensions inherent in key policy goals, opening up spaces for local resistance as well as selective policy implementation. This highlights the open‐ended and contested nature of China's environmental state project.     

The Rejected Candidate: John III Vasa,the Polish-Lithuanian royal elections (1573/1575) and early-modern political decision-making

This article analyses the candidacy of King John III Vasa in the royal elections of Poland-Lithuania in 1573 and 1575. Although the ‘Polish-minded’ policy of John Vasa is commonly known in earlier historiography, Swedish and Finnish historians have not given much attention to John III’s election campaigns in Poland-Lithuania in the 1570s. This article contemplates John III’s candidacy and rejection from the perspective of Poland-Lithuania. The royal elections are analysed as a political decision-making process by the Polish-Lithuanian estates. Thus the article emphasizes the existence of past alternatives and conditions of decision-making in early-modern history.     

External Ties and the Reduction of Knowledge Asymmetries among Clusters within Global Value Chains: The Case of the Ceramic Tile District of Castellon

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.
