Der Scharlatan auf dem Rechtsweg — und was vielleicht zu seiner Umlenkung getan werden könnte

A number of recent allegations of scientific misconduct in Germany have led to judicial proceedings. Two examples are analyzed in depth, showing evidence for mutual incompatibilities between the legal system and the scientific system. In particular, it seems doubtful whether basic rules of good scientific practice are adequately and consistently taken into account by the courts when assessing the burden of proof. Strengths and weaknesses of some alternatives to judicial proceedings in such cases are discussed.     

Pliny the Elder and Sr–Nd isotopes: tracing the provenance of raw materials for Roman glass production

In Roman and Byzantine times, natron glass was traded throughout the known world in the form of chunks. Production centers of such raw glass, active from the 4th to 8th century AD, were identified in Egypt and Syro-Palestine. However, early Roman primary glass units remain unknown from excavation or scientific analysis. The ancient author Pliny described in 70 AD that besides Egyptian and Levantine resources, also raw materials from Italy and the Gallic and Spanish provinces were used in glass making. In this study, the primary provenance of 1st–3rd century AD natron vessel glass is investigated. The use of combined Sr and Nd isotopic analysis allows the distinguishing and characterizing of different sand raw materials used for primary glass production. The isotope data obtained from the glass samples are compared to the signatures of primary glass from known production centers in the eastern Mediterranean and a number of sand samples from the regions described by Pliny the Elder as possible sources of primary glass. Eastern Mediterranean primary glass has a Nile dominated Mediterranean Nd signature (higher than −6.0 ? Nd), while glass with a primary production location in the western Mediterranean or north-western Europe should have a different Nd signature (lower than −7.0 ? Nd). Most Roman glass has a homogeneous ⁸⁷Sr/⁸⁶Sr signature close to the modern sea water composition, likely caused by the (intentional) use of shell as glass raw material. In this way, strontium and neodymium isotopes now prove that Pliny's writings were correct: primary glass production was not exclusive to the Levant or Egypt in early Roman days, and factories of raw glass in the Western Roman Empire will have been at play.     

‘Caught’ between foreign cultural and development policies: perspectives of German Studies and German as a foreign language in Africa

The promotion of the German language abroad and of German Studies plays a central role in German Foreign Cultural Policy. With regard to Sub-Saharan Africa, otherwise a peripheral region for foreign policy, German as foreign language is firmly established as second language after English. Learners especially in Francophone West and Central Africa have increased over the past decade. Numerous funding programmes and actions are supported by German nongovernmental organizations at college/university levels. But bilateral cooperation between German and African academic institutions are challenged both by negative perceptions of the ‘Global South’ among Western colleagues and by an infrastructure adverse to research and to career development in most African countries. Additionally, North/South relations are traditionally seen in terms of (under-)development by German institutions, effecting cooperation. The paper develops a differentiated picture of African Studies in Africa, and outlines benefits that can be attained through collaboration ‘at eye-level’.
