The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described. 相似文献

The Copyright Licensing and Administration Society of Singapore was established in 1999. It is now profitable and commercially significant, perhaps uniquely so in Asia. Critical factors in its growth have included a statutory (non‐voluntary) photocopying licence provision for educational institutions in the Copyright Act; and widespread support from the local and international communities of rightsholders. Tentative consensus has been established with educators over a fair level of remuneration for copying. Further work needs to be done to extend or amend the current model for electronic copying, for the private sector and for other countries in the region. 相似文献

During the rewriting of its program in the early 1980s, theRassemblement pour la République (RPR) carried out anumber of opinion surveys. The person in charge of this wasnot a member of the inner leadership circle; he warned the partyleader, Jacques Chirac, that themes forming a coherent ‘liberal’program for the transformation of the relationship between citizens,state, and the economy, were not popular with public opinion,which remained attached to progressive taxation and a comprehensivesocial welfare system. The party leadership ignored these warnings.Rather than attempting to align their policies with voter aspirations,their principal use of political communications techniques aimedat improving their leader's image. The person in charge of thiswork was a stranger to politics whose understanding of the waycultural or political attitudes are changed led him to interpretvery fatalistically the chances of influencing election outcomesby communications techniques. His methods were treated withfrank skepticism by party communications colleagues, his client'spersonality was particularly unamenable to his efforts, andhis one successful initiative—the rejuvenation of theexecutive committee—was operated at the cost of a rowin the party. In the case of the RPR, opinion research seemsto have played no role at all in an important party policy review,the causes of which should be sought elsewhere. 相似文献
