Estimating the potential impacts of open access to research findings

Advances in information and communication technologies are disrupting traditional models of scholarly publishing, radically changing our capacity to reproduce, distribute, control, and publish information. The key question is whether there are new opportunities and new models for scholarly publishing that would better serve researchers and better communicate and disseminate research findings. Identifying access and efficiency limitations under the subscription publishing model, this paper explores the potential impacts of enhanced access to research outputs using a modified Solow-Swan model, which introduces ‘accessibility’ and ‘efficiency’ parameters into calculating returns to R&D. Indicative impact ranges are presented for Government, Higher Education and Australian Research Council R&D expenditures. We conclude that there may be substantial benefits to be gained from more open access to research findings

Coiled armrings: an Hiberno-Viking silver arm-ring type

The purpose of this paper is to isolate and discuss a distinctive type of Hiberno-Viking silver armring. Here termed the 'coiled armring', it is dated to the late ninth/early tenth centuries. The methods of manufacture, ornamentation, date and origins of the type are discussed and the objects are assessed against the background of hoard-associated material and related types of silver armrings. A descriptive catalogue of the material is provided

Bullion rings in Viking Age Britain and Ireland

This paper examines a simple type of silver ring, here termed the ‘bullion-ring’, that occurs in several Viking Age contexts in Britain and Ireland. It is proposed that the type may be dated to the later ninth and early to mid-tenth century, and that it developed in Ireland as a convenient way of storing silver as a result of inspiration from southern Scandinavia. Its distribution patterns suggest that it may have developed in one of Munster’s Scandinavian settlements rather than in Dublin, the core of the Hiberno-Scandinavian silver-working tradition
