We present a general method of generating continuous fractal interpolation surfaces by iterated function systems on an arbitrary data set over rectangular grids and estimate their Box-counting dimension.

A recurrent iterated function system (RIFS) is a genaralization of an IFS and provides nonself-affine fractal sets which are closer to natural objects. In general, it's attractor is not a continuous surface in R3. A recurrent fractal interpolation surface (RFIS) is an attractor of RIFS which is a graph of bivariate continuous interpolation function. We introduce a general method of generating recurrent interpolation surface which are at- tractors of RIFSs about any data set on a grid.

The TRIM.SP program which is based on the binary collision approximation was changed to handle not only repulsive interaction potentials, but also potentials with an attractive part. Sputtering yields, average depth and reflection coefficients calculated with four different potentials are compared. Three purely repulsive potentials (Meliere, Kr-C and ZBL) are used and an ab initio pair potential, which is especially calculated for silicon bombardment by silicon. The general trends in the calculated results are similar for all potentials applied, but differences between the repulsive potentials and the ab initio potential occur for the reflection coefficients and the sputtering yield at large angles of incidence.

Hintergrund und Ziel: Ausgehend von einem Forschungsdefizit im Bereich von Performance-Tests, das von der Arbeitsgruppe um Bührlen et al. (2002) gekennzeichnet wurde, war es das Ziel der Arbeit einen Performance-Tests of lower limb activities (Polla) zu validieren. Methode: In einer Längsschnittstudie wurden die Ergebnisse einer sechswöchigen physiotherapeutischen Behandlung an einem 19-75jährigem orthopädisch-traumatologisch orientierten Patientenkollektiv (n=81) mit dem Polla und dem SF-36 Fragebogen erfasst. Ergebnisse: Die Ergebnisse machen eine gute Absicherung der Teststatistik deutlich. Bei ausgezeichneter Intrarater- (n=29) sowie guter Interrater-Reliabilität (n=32) weist die Konsistenzanalyse eine zufrieden stellende Zuverlässigkeit auf. Die Kriteriumsvalidität macht moderate Zusammenhänge zwischen dem Polla und den Dimensionen Schmerz, Körperliche Rollenfunktion und Körperliche Funktionsfähigkeit des SF-36 deutlich. Über die Standardized Response Mean zeigen die Instrumente eine große Änderungssensitivität, die nur für den Polla auch zum Follow-up (n=26) gilt. Schlussfolgerung: Der Polla ist ein kostenloses Testverfahren mit hoher praktischer Relevanz, wobei aus zeitökonomischen Gründen eine modifizierte Form des Polla mit nur zehn Items und einem gemessenen Test zu empfehlen ist.

Occupations of higher education institutions such as public relations offices, research liaison offices etc. are increasing. A study related to research liaison officers was conducted in Germany to identify activity profiles and qualifications. Results show no standardised education or training, but only learning by doing. From the viewpoint of professionalisation theories a reasonable professionalisation can only be achieved through an organisation of the various occupations in the field of med-level university management as a whole. Proposals for professionalisation were made, such as more systematic education and improved integration into the organisation of HEIs. Staff development is needed as well as more jobs.
