R&D and Employment: Some Evidence from European Microdata

After discussing theory regarding the consequences of technological change on employment and surveying previous microeconometric literature, our aim with this paper is to test the possible job creation effect of business R&D expenditures, using a unique longitudinal database covering 677 European manufacturing and service firms over the period 1990-2008. The main outcome from the whole sample dynamic LSDVC (Least Squared Dummy Variable Corrected) estimate is the labour-friendly nature of companies’ R&D, the coefficient of which turns out to be statistically significant, although not very large in magnitude. However, the positive and significant impact of R&D expenditures on employment is detectable in services and high-tech manufacturing but absent in the more traditional manufacturing sectors. This means that we should not expect positive employment effects from increasing R&D in the majority of industrial sectors. This is something that should be borne in mind by European innovation policy makers having employment as one of their specific aims.manufacturing, employment, innovation, services, LSDVC

Is Open Source about innovation? How interactions with the Open Source community impact on the innovative performances of entrepreneurial ventures

Practitioners generally assert that collaboration with the Open Source software (OSS) community enables young software firms to achieve superior innovation performance. Nonetheless, to the best of our knowledge, scholars have never extensively speculated about this assertion or rigorously tested it. In this paper, we attempt to do so. First, we root on the entrepreneurship literature and on the OSS research stream to discuss and empirically investigate whether entrepreneurial ventures collaborating with the OSS community (OSS EVs) achieve innovation performance superior to that of their non-collaborating peers. Then, we refer to the concept of absorptive capacity to determine which factors make OSS EVs better able to leverage their collaboration with the OSS community for innovation purposes. Our econometric estimates use a sample of 230 firms and indicate that OSS EVs collaborating with the OSS community achieve superior innovation. At the same time, the impact of community collaborations on innovation is stronger for EVs that are endowed with more skilled human capital, have experience with firm- OSS community collaboration, and actively contribute to the community.Entrepreneurial ventures, Open Source, firm-community collaboration, innovation performance

Conceptual Analogies Between Multi-Scale Feeding and Feedback Cycles in Supermassive Black Hole and Cancer Environments

Adopting three physically-motivated scales (micro - meso - macro, which refer to mpc - kpc - Mpc, respectively) is paramount for achieving a unified theory of multiphase active galactic nuclei feeding and feedback, and it represents a keystone for astrophysical simulations and observations in the upcoming years. In order to promote this multi-scale idea, we have decided to adopt an interdisciplinary approach, exploring the possible conceptual similarities between supermassive black hole feeding and feedback cycles and the dynamics occurring in human cancer microenvironment.Comment: Multidisciplinary article on Frontiers of Oncology (published on May 11th 2021

Inertial particles in homogeneous shear turbulence: Experiments and direct numerical simulation

The properties of the transport of heavy inertial particles in a uniformly sheared turbulent flow have been investigated by combining experimental and numerical data at particle Stokes number St ≈ 0.3 ÷ 0.5 respectively. As in isotropic turbulence, particles are observed to avoid zones of intense enstrophy and to cluster in strain-dominated regions, resulting in highly intermittent spatial distributions. Moreover, the anisotropy of the mean flow is found to imprint a clear preferential orientation of the particle clusters in the direction of the maximum mean strain. These features are observed both in the numerics and in the experiments, and have been consistently quantified by a number of complementary statistical tools, such as the Voronoï tessellations and the pair correlation function. The latter quantity has been generalized in the form of the Angular Distribution Function and has allowed to evaluate the anisotropy content of the particle field at each scale. The behavior of this observable exhibits the same trend in the two datasets and suggests that, owing to increased inertia, the particle distribution starts to recover isotropy at scales smaller than the carrier velocity field. A proper rescaling of the two datasets in terms of their respective values of the shear scale allows to account for differences in the Reynolds number of experiments and numerics in the range of scales dominated by the mean shear. © 2013 Springer Science+Business Media Dordrecht
