Tourism as a vehicle for regional development in peripheral areas – myth or reality? A longitudinal case study of Swedish regions

In the contemporary so-called ‘competition state era’, many rural and peripheral regions are in decline. Tourism is increasingly viewed as being able to alleviate and rejuvenate regions that are facing economic difficulties. The European Union has launched several programmes with the goal of stimulating growth and employment in peripheral areas. These programmes are often used to support tourism development projects. In this paper, a longitudinal analysis of spatial changes in Swedish tourism is conducted. The analysis is based on statistics regarding overnight stays in Swedish commercial accommodation facilities. The aim is to investigate if tourism and tourism policy contribute to the reduction in disparities between regions. Although there are exceptions, the main findings indicate that the potential for creating sustainable rural tourism growth through tourism policy seems to be much less than the popular discourse suggests.     

Coast–inland mobility and diet in the Danish Mesolithic and Neolithic: evidence from stable isotope values of humans and dogs

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ¹³C values surprisingly similar to those seen in marine fish. We propose a model, based on δ¹³C and δ¹⁵N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.     

New excavations at the Barbar Temple, Bahrain

In 2004 excavations at the Barbar Temple dating to c. 2000 BC established that the function of the southeastern subterranean channel connected to the temple pool was to supply the pool with water and not to divert water away from the pool. North and west of the temple the oval terrace wall of its third phase was located. In the centre of the Northeast Temple the remains of a shaft-stairway leading down to a well-chamber was uncovered and shown to be furnished with two subterranean channels leading water into the chamber. South of the Northeast Temple a house with late pottery was excavated. Two stamp seals and two seal-impressed tokens were found.     

3D numerical modeling of hydrothermal processes during the lifetime of a deep geothermal reservoir

Understanding hydrothermal processes during production is critical to optimal geothermal reservoir management and sustainable utilization. This study addresses the hydrothermal (HT) processes in a geothermal research doublet consisting of the injection well E GrSk3/90 and production well Gt GrSk4/05 at the deep geothermal reservoir of Groß Schönebeck (north of Berlin, Germany) during geothermal power production. The reservoir is located between ?4050 to ?4250 m depth in the Lower Permian of the Northeast German Basin. Operational activities such as hydraulic stimulation, production (T = 150°C; Q = ?75 m³ h^?1; C = 265 g l^?1) and injection (T = 70°C; Q = 75 m³ h^?1; C = 265 g l^?1) change the HT conditions of the geothermal reservoir. The most significant changes affect temperature, mass concentration and pore pressure. These changes influence fluid density and viscosity as well as rock properties such as porosity, permeability, thermal conductivity and heat capacity. In addition, the geometry and hydraulic properties of hydraulically induced fractures vary during the lifetime of the reservoir. A three‐dimensional reservoir model was developed based on a structural geological model to simulate and understand the complex interaction of such processes. This model includes a full HT coupling of various petrophysical parameters. Specifically, temperature‐dependent thermal conductivity and heat capacity as well as the pressure‐, temperature‐ and mass concentration‐dependent fluid density and viscosity are considered. These parameters were determined by laboratory and field experiments. The effective pressure dependence of matrix permeability is less than 2.3% at our reservoir conditions and therefore can be neglected. The results of a three‐dimensional thermohaline finite‐element simulation of the life cycle performance of this geothermal well doublet indicate the beginning of thermal breakthrough after 3.6 years of utilization. This result is crucial for optimizing reservoir management. Geofluids (2010) 10 , 406–421     

The Eulau eulogy: Bioarchaeological interpretation of lethal violence in Corded Ware multiple burials from Saxony-Anhalt, Germany

The Corded Ware is one of the major archaeological traditions of Late Neolithic Europe. Its burial customs are characterized by single graves but multiple burials also occur. We present a detailed study of antemortem and perimortem trauma in a group of Corded Ware skeletons from four multiple graves and give the most probable interpretation of the site, based upon all available bioarchaeological evidence. The pattern of observed injuries in male, female, and subadult skeletons, including cranial trauma, arrow wounds, and fractures of the forearm and hands points towards a violent event that resulted in the death of all individuals, most probably a raid. In contrast to comparable Neolithic raid sites, there was no complete extermination of the local population and no use of mass graves. The burials have been arranged with care and detailed knowledge about biological kinship ties [Haak, W., Brandt, G., de Jong, H.N., Meyer, C., Ganslmeier, R., Heyd, V., Hawkesworth, C., Pike, A.W.G., Meller, H., Alt, K.W., 2008. Ancient DNA, strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age. Proceedings of the National Academy of Sciences of the United States of America 105, 18226–18231]. The combination of clear causes of death and the proven biological relationships among some of the individuals, including a nuclear family, provides new and important insights into Corded Ware mortuary customs and the reasons why and how multiple graves have been utilised.     

Knowledge Networks as a Regional Development Resource: A Network Analysis of the Interlinks between Scientific Institutions and Regional Firms in the Metropolitan region of Hanover,Germany

The debate on regional innovation potentials has concentrated in recent times upon the topic of regional knowledge networking. This article presents the findings of the first phase of a detailed network analysis of the cooperation relations between scientific institutions and firms in the “metropolitan region Hanover-Brunswick-Göttingen”. The research concentrated on the regional and supra-regional cooperation relations of approximately 500 science establishments of the region, including their interlinks with private sector firms. This analysis of a polycentric metropolitan region's knowledge networks in different fields of competence produced detailed information on the density of knowledge interlinking within the region, on the degree of connectivity between the region's scientific institutions and private sector firms, and on central network nodes within the regional innovation networks. The case study exemplifies the methodical approach of a regional network analysis and emphasizes the role of knowledge networks as a development resource which is of particular relevance to the region's innovation capacities.     

Dating the Trollesgave site and the Bromme culture – chronological fix-points for the Lateglacial settlement of Southern Scandinavia

The Bromme culture belongs to the Lateglacial, the period when people settled in the recently deglaciated Southern Scandinavia. Until now there have been only a few imprecise fix-points relating to the chronological position of this archaeological culture. This situation can now be improved with the aid of research results from a Bromme culture settlement at Trollesgave in SE Denmark. Using pollen and plant macrofossil data, Lateglacial lacustrine deposits containing waste material from the settlement can be assigned to the end of the climatically mild Allerød period. A series of ¹⁴C dates establishes the age of the settlement as c. 10 826 ± 49 ¹⁴C years BP (12 871–12 590 cal yr BP). By correlation with climate data from the Greenland ice cores, the occupation can be assigned to the early part of the cold climatic zone GS-1, thus demonstrating that the global ice-core climate zones are not absolutely synchronous with the regional division into biozones.
