Gesellschaftliche Alterung als Herausforderung für betriebliche Arbeitsmärkte:eine Expertenstudie in ausgewählten Betrieben in der Region Rhein/Ruhr

Die vorliegende Dissertation untersucht, mit welchen betrieblichen Strategien und Konzepten auf den demographischen Wandel und die gesellschaftlichen Alterungsprozesse reagiert werden kann. Die zentrale Frage beschäftigt sich mit den Möglichkeiten, die Unternehmen zur Verfügung stehen, im Rahmen einer generationengerechten Personalentwicklung eine angemessene Antwort auf die demographische Herausforderung zu finden und ihre Wettbewerbsfähigkeit mit alternden Belegschaften aufrechtzuerhalten. Zur Beantwortung dieser Frage werden Handlungsstrategien entwickelt und diskutiert. Aus diesen Strategien wird ein "Integratives Handlungskonzept zur alternsgerechten Personalentwicklung" erarbeitet, das Wege zu einem humanen und ökonomisch sinnvollen Umgang mit den demographischen Herausforderungen aufzeigt. In einer qualitativen empirischen Studie wird das Handlungskonzept anhand von problemzentrierten Experteninterviews mit Praktikern auf seine Akzeptanz und Realisierbarkeit hinterfragt

How to make universal, voluntary testing for COVID-19 work? A behavioural economics perspective

Testing is widely seen as one core element of a successful strategy to curtail the COVID-19 pandemic and many countries have increased their efforts to provide testing at large scale. As most democratic governments refrain from enacting mandatory testing, a key emerging challenge is to increase voluntary participation. Using behavioural economics insights complemented with data from a novel survey in the US and a survey experiment in Luxembourg, we examine behavioural factors associated with the individual willingness to get tested (WTT). In our analysis, individual characteristics that correlate positively with WTT include age, altruism, conformism, the tendency to abide by government-imposed rules, concern about contracting COVID-19, and patience. Risk aversion, unemployment, and conservative political orientation correlate negatively with WTT. Building on and expanding these insights may prove fruitful for policy to effectively raise people’s propensity to get tested

Effectiveness of Actuating on Rectilinear Bicycle Braking Dynamics

The aim of this study is to quantize the effectiveness of actuating on bicycle braking dynamics with focus on critical rectilinear maneuvers, namely wheel-lock and nose-over. Those situations define the physical limits of rectilinear bicycle braking. The objective is to gain a profound understanding of the limits of unactuated vehicle dynamics by creating a multibody model that is parametrized and validated via an instrumented bicycle. A good model accuracy is obtained modeling the rider as a point mass located at the experimentally determined center of gravity and using tire slip curves which are also gained by experiment. In the second step the obtained system knowledge is used to evaluate possible ways of actuation, which on the one hand could assist the rider not to leave the limits of braking dynamics and on the other hand extend them. Researched types of actuation are brake torque modulation, suspension fork locking as well as active manipulation of the riders center of gravity by a seatpost actuator
