    Notes: A highly resistive phonolitic body near Sainerholz / Westerwald in Germany has been investigated for geological mapping using vertical electrical soundings in a Schlumberger configuration. Because of its explicitly three-dimensional shape, conventional 1D and 2D interpretation techniques are not applicable. Therefore, a new 3D finite-difference forward modelling algorithm has been applied to acquire information about its subsurface structure and to explain the observed data. This investigation focuses on two exposed soundings: one located near the centre of the body and the other close to its rim. For the interpretation, data from electromagnetic measurements on the lateral extension of the body are additionally taken into account as well as geological a priori information. A possible 3D conductivity model is presented and evidence for its validity is discussed using model studies and sensitivity analyses. The latter are carried out using a newly developed 3D FD sensitivity modelling code with which the total subsurface response can be decomposed. This permits the determination of the resolution of model parameters, indicating the contribution of different parts of the model to the overall response. The results emphasize the feasibility of 3D forward modelling in practice.

    Notes: Evaluation of an innovative curriculum: nursing education in the next century The present research focused on an interim evaluation of a new nursing curriculum made by first- and second-year undergraduates. Study 1 examined the assessments made by 90 students of the new, actual programme of their studies, as well as an ideal one, on 21 bipolar criteria reflecting the developing changes in health care practices and higher educational processes in western society. The results of study 1 indicated that students perceived the actual programme as compatible with health care changes, but lacking in terms of the learning process. Study 2 investigated the same assessments among 105 registered nurses who evaluated the traditional nursing programme under which they were trained as well as an ideal one. The results of study 2 showed that registered nurses perceived past curricula as lower than the ideal on both health care and process of learning. The results of this interim evaluation imply that the new nursing curriculum follows health care trends, but a shift in the educational process is required.
