Restoration Techniques Applied to Tile Dome Conservation in the Western Mediterranean. Valencia,Spain

The domes studied, widespread in a large area of the Mediterranean, constitute an architectural heritage of great value to the history of architecture and construction. They were all built using brick masonry and ceramic tile roofs. Restoration work has made it possible to define their geometry, including the construction layouts of the buildings. In addition, on inspection it can be seen that common construction problems tend to be located at specific critical points. The restoration process of different cases sharing the same methodology, construction criteria, and solutions is accurately described. Following international charters, there is minimal intervention and maximum respect for the original solutions, but also a carefully considered incorporation of new materials and technologies to improve the critical points.     

Terrestrial and maritime taphonomy: differential effects on spatial distribution of a Late Pleistocene continental drowned faunal bone assemblage from the Pacific coast of Chile

Site GNL Quintero 1 (GNLQ1), located on the central coast of Chile, is the only documented Late Pleistocene drowned terrestrial site along the Pacific Coast of South America. Faunal evidence at the site is varied, and so far, remains of the following taxa have been found: extinct Camelidae, Cervidae, Equidae, Mylodontidae, Xenarthra, but also Myocastoridae, Canidae and Octodontidae. Both geological and paleoenvironmental data indicate that GNLQ1 developed in a floodplain or low-energy environment during the Last Glacial Maximum (LGM). Prior to the post-glacial rising of the sea level, the site would have been located several kilometres inland as the paleoshoreline was farther out on the continental shelf. In accordance with this background, the present study addresses the analysis of the spatial distribution of the bone deposits of GNLQ1 by considering both scenarios, the terrestrial phase related to the formation and modification of the fossil assemblage prior to the transgression, and the marine phase, subsequent to inundation. Results indicate modifications related to low-energy flow environment and carnivore activity dominated during the terrestrial phase and the action of marine organisms during the marine phase. Other taphonomic modifications are not easily attributable to either one or the other environmental context.     

Hydrogeology of the Krafla geothermal system,northeast Iceland

The Krafla geothermal system is located in Iceland's northeastern neovolcanic zone, within the Krafla central volcanic complex. Geothermal fluids are superheated steam closest to the magma heat source, two‐phase at higher depths, and sub‐boiling at the shallowest depths. Hydrogen isotope ratios of geothermal fluids range from ?87‰, equivalent to local meteoric water, to ?94‰. These fluids are enriched in ¹⁸O relative to the global meteoric line by +0.5–3.2‰. Calculated vapor fractions of the fluids are 0.0–0.5 wt% (~0–16% by volume) in the northwestern portion of the geothermal system and increase towards the southeast, up to 5.4 wt% (~57% by volume). Hydrothermal epidote sampled from 900 to 2500 m depth has δD values from ?127 to ?108‰, and δ¹⁸O from ?13.0 to ?9.6‰. Fluids in equilibrium with epidote have isotope compositions similar to those calculated for the vapor phase of two‐phase aquifer fluids. We interpret the large range in δD_EPIDOTE and δ¹⁸O_EPIDOTE across the system and within individual wells (up to 7‰ and 3.3‰, respectively) to result from variable mixing of shallow sub‐boiling groundwater with condensates of vapor rising from a deeper two‐phase reservoir. The data suggest that meteoric waters derived from a single source in the northwest are separated into the shallow sub‐boiling reservoir, and deeper two‐phase reservoir. Interaction between these reservoirs occurs by channelized vertical flow of vapor along fractures, and input of magmatic volatiles further alters fluid chemistry in some wells. Isotopic compositions of hydrothermal epidote reflect local equilibrium with fluids formed by mixtures of shallow water, deep vapor condensates, and magmatic volatiles, whose ionic strength is subsequently derived from dissolution of basalt host rock. This study illustrates the benefits of combining phase segregation effects in two‐phase systems during analysis of wellhead fluid data with stable isotope values of hydrous alteration minerals when evaluating the complex hydrogeology of volcano‐hosted geothermal systems.     

The Political Economy of Israeli-Palestinian Interdependence

The Israeli and Palestinian economies are asymmetrically interdependent. Some scholars argue that the Palestinian economy cannot be viable alone. Others believe that economic links with Israel will promote peace. Supporters of separation argue that these links distort Palestinian development. I show that the current interdependence is associated with a cyclical Israeli-Palestinian violence and Palestinian economic decline. Assuming that an independent Palestinian state forms in most of the West Bank and Gaza Strip, I argue that Israeli-Palestinian relations require economic separation to be stable. Economic separation will deteriorate Palestinian welfare in the short run. Policies to make it viable are considered.     

Evaluierung in der Diskussion:

Insbesondere in Zeiten knapper ?ffentlicher Finanzen haben Politik, Wirtschaft und Privathaushalte ein Interesse daran zu erfahren, ob die in zahlreichen F?rderprogrammen gebundenen Steuermittel effektiv, zielgenau und erfolgreich eingesetzt werden. über die Erfolgskontrolle von staatlichen Interventionsprogrammen hinaus werden zunehmend auch Institutionen, Instrumente und Beurteilungskriterien auf ihre Wirkung hin untersucht. Daher hat in jüngster Zeit nicht nur in den technischen Disziplinen, sondern auch in den planungsbezogenen und sozialwissenschaftlichen Fachrichtungen verst?rkt die Diskussion um Evaluierungen, ihre wissenschaftliche Genauigkeit, gesellschaftliche Akzeptanz sowie politische Brisanz eingesetzt. Verb?nde und Einrichtungen versuchen, die wissenschaftlichen und ethischen Standards für die Evaluation zu verbessern und neue angepa?te Evaluationsrichtlinien zu entwickeln. Um so erstaunlicher ist es, da? bis heute kaum ein wirklicher Durchbruch einer ausgepr?gten Evaluationskultur in Deutschland zu erkennen ist. So gilt es zu fragen, welche Erfahrungen es in Deutschland diesbezüglich gibt, welche St?rken und Schw?chen sich in der Vergangenheit erkennen lie?en und welche Methoden angesichts ver?nderter Rahmenbedingungen bei welchen Problemstellungen geeignet sind. Schlie?lich empfiehlt es sich, auf die Erfahrungen anderer L?nder zu blicken, um zu lernen, wie wir eine neue Evaluationskultur entwickeln k?nnen. Die Begriffe Evaluation und Evaluierung werden in diesem Text synonym verwendet, wie es auch sonst üblich ist.     

EMPIRICAL STUDIES IN INDUSTRIAL LOCATION: AN ASSESSMENT OF THEIR METHODS AND RESULTS*

ABSTRACT This paper surveys recent evidence on the determinants of (national and/or foreign) industrial location. We find that the basic analytical framework has remained essentially unaltered since the early contributions of the early 1980s while, in contrast, there have been advances in the quality of the data (more firm and plant level information, geographical disaggregation, panel structure, etc.) and, to a lesser extent, the econometric modeling. We also identify certain determinants (neoclassical and institutional factors) that tend to provide largely consistent results across the reviewed studies. In light of this evidence, we finally suggest future lines of research.     

Emergence,collapse and continuity of the first political system in the Guadalquivir Basin from the fourth to the second millennium BC: The long-term sequence of Úbeda (Spain)

Over the last decade, a long-running archaeological project in the Guadalquivir Basin (Spain) has identified the emergence (c. 3000 BC) and collapse (between c. 2500 and c. 2300 BC) of a regional inter-settlement hierarchical system centred on the south-western Pyrite Belt and the Lower Guadalquivir Basin.     

Planning Innovations in Land Management and Governance in Fragmented Rural Areas: Two Examples from Galicia (Spain)

Land fragmentation can be an important drawback for the development of rural areas. Due to the small size of the units, land management and planning are difficult from both the private and the public point of view. In some regions of Europe, land fragmentation can lead to the collapse of land-based activities such as agriculture and forestry. This process triggers land abandonment, which causes social, economic and environmental problems. Traditional interventions such as land consolidation have not worked because of the scale of land fragmentation, which leads to huge transaction costs. New planning instruments and governance structures for land management that balance the relations between property rights, management and labour force can be developed, in order to avoid the problems of land fragmentation. In this paper, we present two innovative examples of land management and governance structures for dealing with land fragmentation in rural areas of Galicia northwestern Spain. They were able to combine the use of individual and common property rights to make land use more sustainable, instead of trying to change land ownership. The new governance structures helped to increase efficiency and sustainability of the land use by, for example, increasing labour productivity, clarifying property rights and diminishing land abandonment.
