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

This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry.  相似文献

Financing universities in times of increasing demands in all fields of public expenditure is a problem of nearly all European counnies not least because of the ongoing process of European integration. Comparing the different national systems of financing universities may be a means to foster cooperation and competition in a step by step growing network of universities in the European Community. This paper tries to give some insights into the German system; special considerotion is given to its federal structure and its implications for the universities' financthg system, because these problems may be of interest to other countries also. Of course this survey cannot be complete; details must be left to detailed information. The first part of the paper gives a survey of the higher education system in the Federal Republic of Gennany. The second part deals with the sources of funds, including the structure of mong streams to the universities. The third part refffs to the restrictions in using state money in the universities and the problems resulting; the fourth and final part concentrates on problems of the future, especially getring third party finds, and the diversifiation. of financing.  相似文献
