This papers aims to study the influence of water absorption on the mechanical properties of poly lactic acid (PLA) and PLA/Wood composites. Virgin PLA and PLA/Wood double-bone-shaped specimens were prepared by two methods: injection moulding and 3D printing. The results were compared to each other and showed the influence of the production method on the properties of the produced parts.

Morphology studies were done by scanning electron microscopy (SEM) from fracture surfaces of tensile and notched impact specimens of all samples. Tensile properties were analysed by the production and testing of dog-bone-shaped samples. Heat deflection temperature (HDT) was tested, as also was the crystallinity of the tested samples by differential scanning calorimetry.

The values for notched impact strength were higher upon water uptake in the case of injection-moulded specimens, which was not the case with 3D-printed specimens. Tensile properties of the specimens produced by both methods were reduced after water absorption tests. Values of the HDT were also lower after water absorption tests studied for both processing methods.

Morphology studies were done by SEM from fracture surfaces of tensile as well as notched impact specimens of injection-moulded and 3D-printed samples. The effect of water storage on various samples was tested. The two different production technologies were compared to each other owing to their influence of water storage. This study also dealt with NFC compounds and produced NFC composites and the influence of water storage on these samples.

The purpose of this paper is to determine whether political skill is equally effective in its prediction of job performance for different job demands.

This paper uses self‐report sources of employee performance and self‐report of political skill after several weeks along with three ratings of target individuals' job demands.

Results support the hypothesis that Holland's enterprising category (i.e. because of its job demands and requisite job competencies to be effective) will moderate the relationship between political skill and job performance, demonstrating stronger predictability under high enterprising job demands.

The present results suggest that political skill is a better predictor of job performance under situations of high enterprising job demands than under conditions of low enterprising job demands. Furthermore, social and conventional job demands do not significantly moderate the political skill‐job performance relationships, implying that these job demands act as an important boundary condition.

Politically skilled individuals are more likely to succeed in environments (e.g. enterprising jobs) where they have the opportunity to exercise interpersonal influence, and where that interpersonal influence is directly related to their performance.

This paper makes several contributions to theory and practice in vocational achievement and political skill. Perhaps, most significant is the identification of job demands as a boundary condition in the political skill‐job performance relationship.

Die Redeweise von der «touristischen Explosion» in der jüngsten Gegenwart gehört ins «Wörterbuch des Unmenschen». Sie kennzeichnet aber drastisch einen Vorgang, dem eine Sprengwirkung nicht ganz abgesprochen werden kann. Jahrtausendalte Gewohnheiten der Sesshaftigkeit wurden seit rund 20 Jahren durch den Tourismus in einem früher unvorstellbaren Ausmass aufgebrochen. Die Erschütterung erfasste auch die Jugend. Das Beben pflanzt sich fort, zeitlich und räumlich, nicht etwa sich verebbend wie bei einem einzigen Erdstoss. Einmal in Schwung gesetzt, wurde der Tourismus allgemein, somit auch jener der Jugend, zu einem perpetuum mobile.
