Isotopic Composition of Lead in Copper Ores and a Copper Artefact from the La Profunda Mine (León,Spain)

This paper continues the characterization of the lead isotopic fingerprint of ancient copper mines in the north‐west of Spain. In this work, the lead isotopic compositions found in copper ores from the La Profunda mine are presented. Azurites and malachites sampled from this deposit were subjected to lead isotope analysis by multicollector ICP–MS. The results showed a clear radiogenic lead signature compatible with the presence of uranium‐rich minerals (such as zeunerite) in the same mining complex. Moreover, a rare copper artefact, found in the galleries of the mine during its modern exploitation, was also analysed and showed that local mineral was used for its manufacturing.     

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.     

Cost Efficiency,Urban Patterns and Population Density When Providing Public Infrastructure: A Stochastic Frontier Approach

Relying on stochastic frontier analysis we propose a methodology to study the technological characteristics and cost efficiency levels related to the provision of public infrastructure for basic utilities. The methodology assumes a cost minimizing behaviour on the part of public officials when planning the construction of local infrastructure, which is represented by way of a flexible translog cost function. Introducing relevant definitions of scale economies, associated with larger numbers of inhabitants and dwellings, as well as economies of density, brought about by reductions in urban dispersion, we analytically determine the optimal population densities for which average cost is minimized. We illustrate our model with the water cycle sector, including water distribution, sewage collection and cleansing of wastewater, and considering data at the municipality level for the Spanish region of Castilla y León. The obtained results indicate potential cost savings in the form of decreasing average costs, as relevant scale and density economies are present, along with large inefficiency levels. Relevant policy guidelines favouring larger and denser urban sizes are drawn, as the observed cost excess is the result of a general suboptimal urban size in terms of population density, and the negative effects of dispersed settlement patterns.     

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.     

Rethinking Twentieth‐Century Guadalajara

This paper discusses the impact of the conference ‘Las Olvidadas: Gender and Women's History in Post‐Revolutionary Mexico’ that took place at Yale University in May 2001, into my own work on women's political mobilisations. It points out from where I departed and how it changed my perspective from women's history to gender history by focusing on women workers in the tortilla industry, a union cacicazgo (political bossism), civic culture, narratives, cultural memory and female political trajectories after the granting of women's suffrage in 1953 in Jalisco.     

Big Game and Small Prey: Paleolithic and Epipaleolithic Economy from Valencia (Spain)

This study analyzes the faunal assemblages corresponding to the Middle and Upper Paleolithic and the Early Epipaleolithic for the central Spanish Mediterranean Region dated from between 135,000 and 9,000 B.P. To interpret these data, we employ a zooarchaeological and paleoeconomic perspective. Human large and small game hunting systems are analyzed through the identification of the origins of faunal assemblages, bone breackage patterns, and prey selection patterns. Our study shows that hunting systems changed significantly through time, which may be related to the characteristics of the Mediterranean ecosystem and, above all, to cultural changes.
