TY - JOUR A1 - Mueller-Seitz, Gordon A1 - Reger, Guido T1 - Is open source software living up to its promises? : Insights for open innovation management from two open source software-inspired projects N2 - At present, several virtual initiatives claim to be acting according to the open source software (OSS) arena, which is often deemed a role model for open innovation. Against this background, this research focuses on a comparative case study of two non-profit project networks that attempt to operate in line with the OSS phenomenon: Wikipedia, the online encyclopedia, and the development of an automobile, Open Source car. We show that many parallels to the OSS arena can be drawn in both cases. However, this analysis must be performed cautiously, as several factors limit the applicability of OSS principles to non-software-related arenas. We conclude with a discussion of implications for open innovation research and managerial practice.

JF - Erkenntnisse zum Wissens- und Technologietransfer N2 - Research on entrepreneurial motivation of university scientists is often determined by quantitative methods without taking into account context-related influences. According to different studies, entrepreneurial scientists found a spin-off company due to motives like independency, market opportunity, money or risk of unemployment (short-term contracts). To give a comprehensive explanation, it is important to use a qualitative research view that considers academic rank, norms and values of university scientists. The author spoke with 35 natural scientists and asked professors and research fellows for their entrepreneurial motivation. The results of this study are used to develop a typology of entrepreneurial and non-entrepreneurial scientists within German universities. This paper presents the key findings of the study (Sass 2011).

Die Initiatoren erfolgreicher Gründungsvorhaben sind oftmals engagierte Hochschullehrer, die nicht nur Anerkennung in der Scientific Community suchen, sondern ihre Forschungsergebnisse ebenso in anwendungsorientierte Produkte und Dienstleistungen überführen. Was treibt diese Wissenschaftler an? In welchem Zusammenhang steht die Gründungsmotivation mit der ursprünglichen wissenschaftlichen Motivation? Ist das Initiieren einer Ausgründung mehr als das Lösen eines herausfordernden Rätsels? Der vorliegende Artikel gibt eine Antwort auf diese Fragen und gewährt einen Einblick in die Gründungsmotivation von Hochschulprofessoren aus den Naturwissenschaften. Mit Hilfe einer qualitativen Untersuchung werden verschiedene Gründertypen gebildet.

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.

Using a yeast-two-hybrid (Y2H) screen with prototype FV (PFV) Gag protein as bait we identified human polo-like kinase 2 (hPLK2), a member of cell cycle regulatory kinases, as a new interactor of PFV capsids. Further Y2H studies confirmed interaction of PFV Gag with several PLKs of both human and rat origin. A consensus Ser-Thr/Ser-Pro (S-T/S-P) motif in Gag, which is conserved among primate FVs and phosphorylated in PFV virions, was essential for recognition by PLKs. In the case of rat PLK2, functional kinase and polo-box domains were required for interaction with PFV Gag. Fluorescently-tagged PFV Gag, through its chromatin tethering function, selectively relocalized ectopically expressed eGFP-tagged PLK proteins to mitotic chromosomes in a Gag STP motif-dependent manner, confirming a specific and dominant nature of the Gag-PLK interaction in mammalian cells. The functional relevance of the Gag-PLK interaction was examined in the context of replication-competent FVs and single-round PFV vectors. Although STP motif mutated viruses displayed wild type (wt) particle release, RNA packaging and intra-particle reverse transcription, their replication capacity was decreased 3-fold in single-cycle infections, and up to 20-fold in spreading infections over an extended time period. Strikingly similar defects were observed when cells infected with single-round wt Gag PFV vectors were treated with a pan PLK inhibitor. Analysis of entry kinetics of the mutant viruses indicated a post-fusion defect resulting in delayed and reduced integration, which was accompanied with an enhanced preference to integrate into heterochromatin. We conclude that interaction between PFV Gag and cellular PLK proteins is important for early replication steps of PFV within host cells.

The sediment deposits are approximately 100 m thick at the first test site and approximately 400 m thick at the second test site. We have used an extended physical model based on the diffuse wavefield assumption for the interpretation of the observed microtremor H/V spectral ratio. The extension includes the interpretation of the microtremor H/V spectral ratio observed at depth (in boreholes). This full-wavefield approach accounts for the energy contribution from the body and surface waves, and thus it allows for inverting the properties of the shallow subsurface. We have obtained the multimode phase velocity dispersion curves from an independent study, and a description of the extracted branches and their interpretation was developed. The inversion results indicate that the combined approach using seismic ambient noise and actively generated surface-wave data will improve the accuracy of the reconstructed near-surface velocity model, a key step in microzonation, geotechnical engineering, seismic statics corrections, and reservoir imaging.

We evaluate the time-dependent Casimir-Polder force on the atom and find that it shows an oscillatory behavior from attractive to repulsive both in time and in space. We also investigate the asymptotic behavior in time of the dynamical force and of related local field quantities, showing that the static value of the force, as obtained by a time-independent approach, is recovered for times much longer than the time scale of the atomic self-dressing but shorter than the atomic decay time. We then discuss the evolution of global quantities such as atomic and field energies and their asymptotic behavior. We also compare our results for the dynamical force on the excited atom with analogous results recently obtained for an initially bare ground-state atom. We show that new relevant features are obtained in the case of an initially excited atom, for example, much larger values of the dynamical force with respect to the static one, allowing for an easier way to single out and observe the dynamical Casimir-Polder effect.
