    This paper briefly surveys how authorisation in Grid computing has evolved during the last few years, and presents the latest developments in which Grid applications can utilise a policy controlled authorisation infrastructure to make decisions about which users are allowed to perform which actions on which Grid resources. The paper describes the Global Grid Forum SAML interface for connecting policy based authorisation infrastructures to Grid applications, and then describes the PERMIS authorisation infrastructure which has implemented this interface. The paper concludes with suggestions about how this work will evolve in the future

    Il logos inciso nell'argilla. Ricordo di John Chadwick

    No full text
    On the centenary of the birth of John Chadwick (who, together with Michael Ventris, deciphered the Cretan script "Linear B"), the author, who knew him personally and corresponded with him, reconstructs and relates unpublished aspects of how Chadwick arrived at his discoveries, thanks to his military decryption experiences during the Second World War. Philosophy had flourished on Greek soil several centuries after Linear B, yet we cannot help but recognise that its basic constituent, the logos, the word as the expression of (future) thought, was indeed born on the clay tablets of Crete.Nel centenario della nascita di John Chadwick (il quale decifrò insieme a Michael Ventris la scrittura cretese “Lineare B”), l’autore, che lo conobbe personalmente ed ebbe con lui uno scambio epistolare, ricostruisce e riferisce aspetti inediti di come Chadwick giunse alle sue scoperte, grazie a esperienze di decrittazione militare risalenti alla Seconda Guerra Mondiale. La filosofia era fiorita sul suolo greco diversi secoli dopo la Lineare B, eppure non possiamo fare a meno di riconoscere che il suo costituente basilare, il logos, la parola in quanto espressione del pensiero (futuro), era davvero nato sulle tavolette d’argilla di Creta

    Chadwick, Liverpool and the bomb.

    No full text
    The author intends to set out in this thesis Chadwick's scientific and diplomatic contribution to the development of the atomic bombs that ended World War Two. The far-reaching consequences of Chadwick's efforts to establish a nuclear physics research prograrmne, both academic and commercial, in austere post-war Britain are also shown. A brief history of Chadwick's academic career, at Manchester, Cambridge and Liverpool Universities is given, which indicate how his intimate knowledge of atomic and nuclear physics culminated in the building of a state-of-the-art 37" pole diameter cyclotron at Liverpool University. The help that Lawrence and his colleagues generously and freely gave to Chadwick is also acknowledged. The crucial role of the Liverpool cyclotron in determining the necessary nuclear fission cross-section measurements needed to establish the feasibility of an atomic bomb, is also discussed. Chadwick's precise and penetrating insight of the bomb's feasibility, was presented in the final Maud Report that was sent, prior to the bombing of Pearl Harbour, to the U.S.A. It was this Report that convinced the Americans that an atomic bomb was a feasible and obtainable objective and started, as a matter of urgency, American fission bomb research. A brief history of fission and the events surrounding its discovery is also presented, as is a comparative discussion on the German and Japanese progress in atomic bomb research in World War Two. It would not have been possible to give specific details of many of the above events without primary source material to substantiate them The author has located a large number of previously un-published letters, documents and photographs - only some of which have been included - but all of which are being incorporated into a Chadwick Archive at Liverpool University
