Conceptualizing the Regional Roles of Universities,Implications and Contradictions

The impact of universities on the economic wellbeing and innovative potential of regions has been the object of intense scholarly and policy interest in the last years. Despite this interest, a clear picture is missing in relation to the roles universities are seen to play, the benefits of university activities and the mechanisms through which they occur. This paper proposes a review and a critique of current views on the role of universities and their associated policy implications. To achieve this, the paper identifies five “models” for universities as they are reflected in the literature, each advocating different set of roles of universities, different spatial aspects of interactions, as well as different mechanisms for university engagement. National and regional innovation and research policies tend to explicitly or implicitly reflect one or a combination of several of these models, giving rise to potential contradictions or conflicts of policy rationales and objectives.     

Western Mediterranean sand deposits as a raw material for Roman glass production

During the Late Roman and Byzantine period, natron glass was made from its raw materials in a limited number of primary production centres in Egypt and Syro-Palestine. For the earlier Hellenistic and Roman period, no primary furnaces have been found and the location of primary production during this era remains unclear. Ancient authors such as Strabo and Pliny the Elder suggest that glassmaking sands were found near the River Belus (Israel), in Egypt, near the mouth of the Volturno River (Italy) and also in Spain and France. However, primary production in the western part of the Mediterranean is not supported by any direct archaeological evidence and possible sand raw materials from these regions have never been evaluated for their suitability to produce glass.
