However, often these studies overlook the soft factor of employee competences which is critical to adopting technological and organizational changes and to developing the necessary innovation capabilities. This study investigates the theoretical and methodological underdeveloped relationship between technological innovation and social initiated change and the impact on individual competences in a dynamic sector. The setting of our study is the turbulent creative industries as a whole, where creative and artistic expression merges with changing technological progress. In a scenario study we mainly conducted in 2010, we developed a scenario model for competences to combine individual competences with a scenario approach to investigate how competences are important to the sector shift or need to be enhanced in the future. We use primary qualitative data from expert interviews and workshops and secondary data from industry reports to identify thirty-seven influence factors. An influence matrix calculation and a cluster analysis are used to project three different scenarios presenting how future developments of the creative industries will influence the competences needed for creative occupations. Now, five years later, we reflect the accuracy of the developed scenarios via a comparison of today's situation with the situation in the scenarios. We discuss theoretical contributions for the foresight literature and practical implementations for the future of work in general, and in particular for the creative industries case.

Nevertheless, their application to sound synthesis has not yet been fully exploited. In this article we present a systematic approach to sound synthesis based on first-order complex and real ODEs. Using simple time-dependent and nonlinear terms, we illustrate the mapping between ODE coefficients and physically meaningful control parameters such as pitch, pitch bend, decay rate, and attack time. We reveal the connection between nonlinear coupling terms and frequency modulation, and we discuss the implications of this scheme in connection with nonlinear synthesis. The ability to excite a first-order complex ODE with an external input signal is also examined; stochastic or impulsive signals that are physically or synthetically produced can be presented as input to the system, offering additional synthesis possibilities, such as those found in excitation/filter synthesis and filter-based modal synthesis.}, language = {en} }
