Radiocarbon calibration in the Anglo-Saxon period: AD 495-725

Radiocarbon dating has been rarely used for chronological problems relating to the Anglo-Saxon period. The "flatness" of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against 14C dates. The calibration process, within such a confined age range, however, relies heavily on the structural accuracy of the calibration curve. We have therefore re-measured, at decadal intervals, a section of the Irish oak chronology for the period AD 495–725. These measurements have been included in IntCal04.

Understanding Corporate Governance Reform in South Africa: Anglo-American Divergence, the King Reports and Hybridization

This article investigates corporate governance reform in South Africa in the context of the country’s international links with Anglo-American corporate governance and domestic pursuit of socioeconomic development. Two key questions are evaluated. (a) How has divergence within the Anglo-American model influenced corporate governance reform in South Africa? (b) Can South Africa’s historical closeness to the Anglo-American model be combined with increasing attention to stakeholder issues to produce a hybrid “African model” of corporate governance? Evaluating these questions, the following issues are explored in turn: the contrast between shareholder and stakeholder models, divergence between U.S. and U.K. approaches to corporate governance as exemplified by Sarbanes-Oxley, locating a South African approach in context of the Anglo-American model, the King reports and an emerging “African” model of corporate governance, and the role of international and domestic factors in shaping South Africa’s ongoing reform process.
