Near infrared spectroscopy as a tool for archaeological wood characterization

Archaeological wood, as most of natural materials, is slowly decomposing on the archaeological site due to various biological factors. Rapid and accurate estimation of the degradation level is extremely important for optimal restoration and conservation. The goal of this research was to verify the effectiveness of Fourier transform near infrared (FT-NIR) spectroscopy for archaeometry. The important advantage of the NIR spectroscopy is its accuracy, simplicity and ability to perform very high number of tests without needs of any destruction to the workpiece. Five oak pieces of the archaeological wood collected from waterlogged sites in Poland have been used. Cellulose and lignin contents, as well as crystallinity and the degree of polymerization were measured with standard reference methods and compared to the contemporary wood. The near infrared spectra represent all the physical/chemical changes of the wood due to waterlogging. This technique was successfully validated in rapid estimation of the cellulose and lignin contents. The method explored in this research might be a novel tool assisting experts in evaluation of the degradation state of archaeological and historical wooden materials.     

From imperial inclusion to national exclusion: citizenship in the Habsburg monarchy and in Austria 1867–1923

This paper examines the development of citizenship in Austria-Hungary between 1867 and the 1920s. At the beginning, the paper analyses the reform of citizenship laws in both Austria and Hungary after the Settlement of 1867. Whilst the Austrian citizenship law maintained legal traditions stretching back into the first half of the nineteenth century, the new Hungarian citizenship law of 1878 emulated the laws in effect in Wilhelmine Germany. The basis of Hungarian citizenship law was, however, much broader than German law, in order to allow for the effective integration of the non-Magyar population. An evaluation of applications for Austrian naturalisation illustrates the remarkable capacity of Austrian citizenship law to integrate and to uphold a concept of nationality independent from ethnicity, religious denomination, class or gender. Only during, and above all after, the First World War did the inclusive practice of the Cisleithanian bureaucracy give way to the more exclusive policy of the new German-Austrian Republic, as civil servants now introduced the vague notion of ‘race’ as a criterion for naturalisation. In contrast to Tsarist Russia and the Second German Empire, both of which introduced similar agendas for nationalisation in the latter part of the nineteenth century linking citizenship to ethnic and religious identity, the Habsburg Monarchy remained basically untouched by such tendencies and with the constitutionally guaranteed principle of ‘national equality’ upheld its early modern tradition of ethnic and religious tolerance well into the later Imperial period.     

Reclip:more Kleinr?umige Klimaszenarien für ?sterreich

Der letzte Bericht des Intergovernmental Panel on Climate Change (IPCC 2007) erl?utert die weltweiten Auswirkungen des Klimawandels deutlich – allerdings aus globaler Sicht. Um zu kl?ren wie sich das regionale Klima in ?sterreich ver?ndern wird, wurde mit dem Projekt „reclip:more“ (Research for Climate Protection: Model Run Evaluation) eine erste kleinr?umige Datenbasis für Klimaschutz und Klimafolgenforschung für ?sterreich generiert. Klimaszenarien wurden mittels regionaler Klimamodelle (RCMs) für die Alpen als 10 × 10-Kilometer-Raster und mit anschlie?endem Downscaling für ?sterreich mit einer Zielaufl?sung 1 km entwickelt. Die RCMs wurden mit ERA-40 Reanalyse-Daten der Vergangenheit und Daten eines Zukunftsszenarios des globalen Klimamodells (GCM) ECHAM5 angetrieben, um retrospektive (1981 bis 1990) und künftige (2041 bis 2050) Klimadatens?tze für die Alpen zu berechnen und M?glichkeiten und Unsicherheiten der Modelle und Downscaling-Methoden für die Alpen zu evaluieren. Die nun vorliegenden Datens?tze und weitere, die im Folgeprojekt „reclip:century“ für alternative Treibhausgasszenarien bis 2100 berechnet werden, dienen dazu als Basis für Aussagen über ?kologische und sozio?konomische Entwicklungen im Hinblick auf den Klimawandel.     

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.     

Abortion law reforms in Colombia and Nicaragua: issue networks and opportunity contexts

This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes.
