The Development in Germany of Archival Processing – The Vertical and Horizontal Appraisal

Based on a discussion about appraisal which has been going on for over a 100 years, the so-called vertical and horizontal appraisal have been developed and tested since the middle of the 1990s. During this process the tasks, functions and competences of the agencies, which are to be appraised were analysed. The appraisal of the content itself is undertaken only when multiple archival processing has been eliminated by this method and the most significant records identified. Actual tasks and functions of single administrative branches of different institutions (federal government, states, counties, and municipalities) are appraised, apart from already closed records. In this way, agencies creating archives and records today receive written decisions on the appraisal of records, which will be offered to the archives in future. Archivists of different institutions are involved in this appraisal procedure. The experience gained here has continually developed the techniques of vertical and horizontal appraisal. This appraisal procedure is being further developed in a constant balance between theory and practice.     

Trends in the Creation and Appraisal of Government Records in Germany

While archivists in western and eastern Germany may have different traditions, they face the same challenges presented by the use of information technology in government offices in recent years. Documentation strategies and goals in advising agencies must be developed in consideration of current professional debate and limited resources. The following article presents tendencies in governmental records management, advising strategies of archives, and schemes for broad-scale appraisal based on observations at the level of the governments of the German Länder and includes case studies from Saxony.     

A mathematical model for power output in rowing on an ergometer

A mathematical model relating power output of rower to stroke rate on an ergometer (the Concept II Indoor Rower TM, Model C) is studied. The model is used to analyse the ergometer performance of a particular rower. It is determined that he can be more efficient (i.e. decrease power output while maintaining fixed velocity) by decreasing stroke rate, but at the expense of increasing force during the drive. It is also shown that he can be more efficient by increasing the drag factor (using higher vent setting) without increasing force. Dependence of power output on rowing style (the shape of the force curve) is also examined. It is shown that variation of force during the drive has little effect on efficiency, but efficiency is reduced by asymmetry of the force curve that favours the legs.
