Regional polycentricity: an indicator framework for assessing cohesion impacts of railway infrastructures

Territorial cohesion has become one of the main objectives in transport planning. This has fostered the development of assessment methodologies to quantitatively estimate the territorial impact of major transport infrastructures, which are particularly scarce at the intra-regional level. Linked to cohesion, polycentricity has been defined as the best spatial configuration to achieve balanced regions where population and opportunities are distributed among several entities linked by functional relationships. This paper aims to present a methodology to estimate these impacts based on the use of a new regional composite polycentricity indicator. The proposed indicator is tested by comparing the effects of conventional and high-speed railway (HSR) alternatives in the territorial system of a northern region of Spain. This quantitative assessment is a ranking tool for prioritizing rail network alternatives in terms of achieving the most balanced territory, which is especially relevant in countries where HSR networks follow cohesion goals. Our results show that new HSR links should only be complementary to regional railway services, and that the suppression of secondary lines should be avoided if a reduction in polarization is to be achieved.     

Feasting and Building an Urban Society at Cerro Jazmín,Oaxaca, Mexico

Here we present new excavation data from the urban site of Cerro Jazmín, Oaxaca, Mexico. Based on a comparative analysis of ceramic, faunal, botanical, and architectural evidence collected from a prominent city sector and a contemporary residence, we argue that feasting took place in the Sunken Patio Sector in the Late and Terminal Formative periods. Feasting strategies in an earlier occupation of the city sector employed a largely exclusionary strategy, giving way to a more corporate strategy in a later occupation. We take the findings from the Sunken Patio feasting complex as evidence of the formalization of Cerro Jazmin’s urban, regional role as a site of civic-ceremonial activity. Participation in this meaningful act of food consumption may have served to cement communal ties in a nascent urban society.     

Application of Non-Destructive Techniques in the Inspection of Wooden Structures of Protected Buildings: The Case of Nuestra Señora de los Dolores Church (Isla Cristina,Huelva)

This study describes a thorough inspection of a 20th century church in the town of Isla Cristina (in the province of Huelva, southwestern Spain), which is currently awaiting restoration. The study indicates the damage processes at work in the building structure materials (brick, concrete, steel, and wood), which are closely related to its geographical location, and analyses the deterioration of the wooden roof structure. The analysis of the wooden roof includes the results of an inspection methodology on a protected building based on traditional techniques such as visual inspection and innovative non-destructive inspection techniques (visual classification, ultrasounds and thermography). Fieldwork consisted of the visual classification of the wooden pieces according to Spanish standard UNE 56544:2007 specifications after which ultrasound and thermography techniques were applied on-site. A second stage involved laboratory tests (anatomic identification, density and bending strength) using wood samples extracted from the structure in order to check the values for the physical and mechanical properties previously recorded by non-destructive techniques (NDT). These non-destructive techniques are used in inspections of the wooden roofs of buildings to identify dampness, deterioration, density loss and defects as a means of assessing their conservation status. This work concludes that the use of ultrasound and thermography techniques constitute an accurate diagnostic tool for the on-site inspection of wooden structures and the evaluation of their condition. Thermography identifies different materials and moisture content while ultrasound detects the various degrees of deterioration and density-loss in areas of the wood with high moisture content.     

Modernizing Insecurity: The Land Titling Project in Honduras

The Honduran land titling project (the Proyecto de Titulación de Tierra para los Pequeños Productores), initiated in 1982, was intended to enhance security in land rights, to facilitate credit and to improve agricultural productivity. This study explores how the project has operated in one village, and concludes that it has attained none of its objectives; instead, it has triggered new sources of land conflicts, thus adding to the existing complex of local rules and laws. The authors argue that the failure of the project is not solely a consequence of the organizational incapacity of the bureaucracy, as some evaluations suggest, but that it is rooted in mistaken assumptions about the social organization of property rights and the causes of insecurity. The land titling project is founded on a contradiction: although based on the ideology of the capitalizing family farm in the context of a withdrawing state, its implementation actually requires strong and repressive state intervention. Rather than reducing insecurity in property rights, the project has merely ‘modernized’ the sources which can be used to contest rights in land.     

Language,Science and Globalization in the Eighteenth Century**

Asia, America, and Europe have been intellectually intertwined for centuries. Several studies have been published revealing European scholars’ interest in the “exotic” languages of Asia and America, as well as in ethnographic and anthropological aspects. Some scholars such as Polymath Leibniz (1646–1716), were interested in these languages in an attempt to construct a universal language, while others tried to establish language families, like the Jesuit Hervás y Panduro (1735–1809). However, all acknowledge the importance of language and the circulation of knowledge. This paper analyzes the dissemination of the compilation of eighteenth-century multilingual lexical compilations for comparative purposes as an early globalized project. These compilations were designed by European scholars and subsequently elaborated in different languages by missionaries, explorers, and scientists in the Philippines and America. Taking the correspondence and relations between botanist Mutis (1732–1808) and bureaucrats, European scientists such as polymath Humboldt (1769–1859) and Botanist Linnaeus (1707–1778) among others, and navy officers of the scientific exploration commanded by Malaspina (1754–1809) and Bustamante y Guerra (1759–1825) into consideration, I will analyze how simultaneous projects followed a unified aim, and illustrate their substantial contribution to the study of language in the late eighteenth century.     

The Rise of the “City-region” Concept and its Development Policy Implications

As well as enjoying a rich scientific history, the concept of the “city-region” has also attracted particular attention in recent years. Combinations of an urban core or cores, linked to semi-urban and rural hinterland by functional ties, are increasingly regarded as the “adequate” scale for the implementation of development policies. The popularization and widespread use of the city-region concept for policy-making has important implications for the design and implementation of development strategies. It first signals a change from sectoral to territorial approaches to development and requires the adjustment of development strategies to widely varying contexts, leading to much greater policy diversity and innovation. It also involves a more complex governance structure, characterized by the horizontal and vertical coordination of numerous institutional public and private actors, and enables experimentation with bottom-up and participatory policy-making. This paper evaluates these changes and critically addresses their normative implications, especially in light of the facts that there is still little agreement on how the city-region is defined, that the term has become appropriated by urban elites, and that the problems faced by city-regions may not be that different from those operating at other geographical scales.     

Regional Scientific Production and Specialization in Europe: The Role of HERD

This paper analyses the effects of R&D expenditure in the higher education sector on the scientific production across regions in Europe 15. Our research questions relate to the regional production of science and the role of academic R&D expenditures on regional scientific output. The results show that money affects the production of scientific results in regions. On average, we found different impacts and lags of R&D expenditure according to the level of regional development. Our findings also suggest that scientific specialization is a significant factor affecting scientific outputs, although its effects differ across disciplines and regions.     

Ancient DNA insights from the Middle Neolithic in Germany

Genetic studies of Neolithic groups in central Europe have provided insights into the demographic processes that have occurred during the initial transition to agriculture as well as in later Neolithic contexts. While distinct genetic patterns between indigenous hunter-gatherers and Neolithic farmers in Europe have been observed, it is still under discussion how the genetic diversity changed during the 5,000-year span of the Neolithic period. In order to investigate genetic patterns after the earliest farming communities, we carried out an ancient mitochondrial DNA (mtDNA) analysis of 34 individuals from Wittmar, Germany representing three different Neolithic farming groups (ca. 5,200–4,300 cal bc) including Rössen societies. Ancient DNA analysis was successful for six individuals associated with the Middle Neolithic Rössen and observed haplotypes were assigned to mtDNA haplogroups H5, HV0, U5, and K. Our results offer perspectives on the genetic composition of individuals associated with the Rössen culture at Wittmar and permit insights into genetic landscapes in central Europe at a time when regional groups first emerged during the Middle Neolithic.
