Abstract
Common approaches for gamepad-based navigation in desktop 3D games are often not suited for inexperienced players. In particular, novices have difficulties in simultaneously controlling movement and viewing direction in a virtual 3D scene. Here, we compare the currently predominant 3D navigation approach with an alternative approach that is inspired by early 3D games. 20 test users with little or no 3D gaming experience used both approaches to walk along a test course in a virtual 3D scene containing different obstacles. Using the alternative navigation approach, the users finished the course faster and with fewer errors than with the predominant navigation approach. In addition, the pragmatic and the hedonic quality of the alternative approach were rated higher. As a conclusion, the presented alternative approach should be given consideration when designing 3D (serious) games or similar applications for inexperienced players, not only for gamepad-based navigation, but also for comparable interfaces like the typical combination of keyboard and mouse control.

Abstract
Within the past ten to fifteen years the concept of Employer Branding (EB) has established itself as a widely known and highly regarded concept especially among Human Resource Management practitioners. In many organizations the development, implementation and communication of a distinctive and unique employer brand is meanwhile considered an important building block for gaining a competitive advantage in the so called “war for talent”. The paper at hand aims at critically exploring the conceptual foundations of employer branding by reviewing an extensive body of EB-literature consisting of standard references, scientific journal articles, textbooks as well as practitioner-oriented literature. This review reveals several general weaknesses, discrepancies and “blind spots” which cannot simply be attributed to some few single publications but rather call for a skeptical look upon the whole concept of employer branding itself. In conclusion the authors assert that the employer branding concept widely lacks innovative novelty as well as content-related persuasiveness. It should therefore be regarded as neither more nor less than a contemporary remake of what is and has for quite some time been well known as “Internal Marketing” or “HR Marketing”.

Abstract
Recent studies have shown a number of procedural similarities between solving problems in mental and in physical rotation. Such similarities open up the interesting option to study mental rotation indirectly through physical rotation, with the advantage that physical rotation processes can be much more easily observed than mental ones. To better assess where solution processes in mental and physical rotation differ, though, it is important to know what influence any specific interaction method in physical rotation will have. We present results from a comparison of two such interaction methods: a one-handed, touch-based and a two-handed, ball-based method. Our analysis focuses on fixation durations and saccade amplitudes as proxies for mental load. Results show, importantly, that the choice of interaction method seems to matter but little. We therefore suggest that the existing findings of past studies that have compared mental to physical rotation are likely highly comparable, despite the fact that different interaction techniques were used.

Abstract
In this paper, the design of a flexible piston accumulator for application in a hydraulic-pneumatic flywheel system in a wind turbine rotor is presented. The flywheel system enables a wind turbine to vary the inertia of its rotor blades to control the power output and, most importantly, to influence the vibratory behaviour of wind turbine components. The method used for designing the flexible accumulator is based on the one hand on test results of a flexible piston accumulator prototype, and on the other hand, on simulation results of a model of a flexible piston accumulator. As a result, a design of flexible piston accumulators for application in the flywheel system is implemented and compared with the design of conventional steel accumulators. Due to the proposed design of the flywheel system, the impact on the mechanical loads of a wind turbine is analysed. The simulation results show that the new design of the piston accumulators causes a lower impact on the mechanical loads of the wind turbine than a previously published design of piston accumulators. It is further shown that the considered wind turbine can take on the flywheel system without the need for reinforcements in the rotor blades.
