Evolution of the Territorial Coverage of the Railway Network and its Influence on Population Growth: The Case of England and Wales, 1871–1931

Abstract

The introduction of the railway network brought with it an unprecedented improvement in accessibility. In this work, the authors analyze the evolution of the territorial coverage of the railway network and its influence on the uneven distribution of population. To carry out this research, they used comparable data on total population obtained from census records relating to civil parishes of England and Wales, taken at 10-year intervals from 1871. The hypothesis that they wished to test was that good access to a railway station was related to significant increases in population. This exercise provides a better understanding of regional variations in population growth and allows the authors to identify current differences between urban and rural areas that have resulted from their historical evolution.     

The southernmost records of Anhingidae and a new basal species of Anatidae (Aves) from the lower–middle Miocene of Patagonia,Argentina

New bird fossils from the Santa Cruz Formation (lower–middle Miocene), Santa Cruz Province, Patagonia, Argentina, are described. They represent an indeterminate species of the extinct anhingid Macranhinga and a new genus and species of basal Anatidae Ankonetta larriestrai. The record of the giant darter Macranhinga constitutes the southernmost record for the family, and expands the known stratigraphic range of the genus, previously restricted to the upper Miocene. Based on an analysis of the fossil anhingid record from South America, we hypothesize that giant darters disappeared from South America in the early Pliocene due to climatic deterioration, regression of marine and freshwater environments, the arrival of placental carnivorous mammals, and also probably by competition with phalacrocoracid cormorants. The new anatid Ankonetta is based on an incomplete but informative tarsometatarsus, with superficial similarities to extant Dendrocygna. A brief overview of several fossil ducks from the Patagonian Cenozoic concludes that most pre-Pliocene examples belong to non-anatine taxa, indicating that plesiomorphic ducks were the dominant anseriforms in those times, a pattern also evident on other continents.     

The Competitive Position of the Basque Aeroespatial Cluster in Global Value Chains: A Historical Analysis

In this paper, based on the case study of the aerospace cluster of the Basque Country (Spain), we aimed at analysing how local industries develop a new specialization, that is, how a cluster emerges, and how it evolves over time. For that purpose, apart from considering local factors (both forces that are internal to the cluster and to the territory), we explicitly consider the role of institutional and technological changes, and how they affect industry structure and governance patterns of global value chains (GVCs). We observe that global-scale regulations (deregulation and competition policy) and technological change, together with local factors such as the existence of anchor firms, local policies, related variety and social capital at regional and cluster levels played a significant role in the emergence of the cluster and how it became inserted in the GVCs. Later on, the development of suppliers' capabilities also had a relevant role in the evolution of the governance patterns of GVCs.     

Application of Particle Motion Technique to Structural Modal Identification of Heritage Buildings

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).     

“Urban Ecology Under Fire”: Water Supply in Madrid During the Spanish Civil War (1936–1939)

This paper investigates the critical role of workers to enhance the resilience of water supply services in cities at war through analyzing the case of Madrid and the Madrid water company Canales del Lozoya during the Spanish Civil War (1936–1939). We argue that securing the protection of vital urban flows mediated through infrastructures is a key objective of cities under attack. In doing so we contend that examining how those affected by the interruption of these flows cope with the situation represents a valuable but largely neglected form of water management. We illustrate how quotidian knowledge about the urban geography of water flows may have important repercussions for the war effort itself. In a nutshell, the case of Madrid offers an early account of the critical role of water workers in sustaining “urban ecologies under fire” securing the complex urban metabolism while also contributing to the struggle against invading forces.     

PERFECT REPRESENTATIONS OF SOVIET PLANNED SPACE

The article looks at mono‐industrial cities in the Baltic States during the Soviet era. In terms of economy, ethnicity and their urban appearance these heterotopic towns were outposts in the integration of the occupied European‐like territories into the Soviet Union. Thanks to the principles of planning and state‐favoured development that were applied across the Soviet Union, these towns, built for Russian speaking immigrants, stood out from the surrounding patterns of settlement that had developed naturally over time. The uranium producing town of Sillamäe in Estonia was built in secret and with lightning speed amidst the panic concerning the atom bomb immediately after the war, and provides us with a perfect model of Stalinist urban development. Stu?ka, built in the 1960s near a hydro‐electric power station in Latvia and Snie?kus, built in the 1970s next to a nuclear power station in Lithuania, were less separated from the surrounding landscape, but both provide a perfect example of Soviet modernism, which had been learned from mass‐housing in the West.
